Effectiveness of Teaching Program on QoL of Elderly Patients

Effectiveness of Teaching Program on QoL of Elderly Patients CHAPTER – 1 INTRODUCTION â€Å"It’s not how old you are, it’s how you are old Live your life and forget your age† Older adults recognize that they have less time in which to continue achieving their goals, so they face their challenges with resilience and determination. Gerontologists are increasingly recognizing that older adults who are aging successfully possess wisdom, which includes factual knowledge, problem- solving strategies, and the ability to manage uncertainty. Because many of the challenges of older adulthood involve health and functioning, older adults need accurate information, not only about aging, but also about interventions to promote wellness. Nurses are ideally positioned to teach older adults about health and aging and empower them to implement problem-solving strategies directed towards wellness, improved functioning, and quality of life (Blazer, Brugman, 2006). With increases in life expectancy, delayed onset of morbidity, and higher expectations for old age, interest in well-being in later life and how to achieve it has intensified. ‘Successful ageing’ has come to the fore as a goal for the ageing population. While an agreed definition of successful ageing remains elusive, there is broad agreement that core constituents include physical health and functioning, psychological wellbeing, and social functioning and participation. As the older population surges both in absolute and relative numbers, well-being in old age has also become a focus for policy-makers as a key indicator of the physical and psychological health, social integration and economic security of the older community (Bowling A, Dieppe P Dec 24). Despite the adverse changes that occur with increasing age, older people typically report high levels of well-being. Most feel younger than their actual age and maintain a sense of confidence and purpose. In the HeSSOP (Health and Social Services for Older People) surveys of older people in Ireland, conducted in 2000 and 2004, over three-quarters of community-dwelling older people scored high on morale (Garavan R, Winder R, McGee H. ; 2001, O’Hanlon A, McGee M, Barker M 2005). In fact, older people are more likely to report satisfaction with their lives than younger people (Strine TW, Chapman DP 2008). Old age, it appears, brings with it an ability to adapt to age- related changes and stresses. One study found, for example, that physical decline did not have an impact on older people’s satisfaction with life, suggesting that they regard it as a normal and relatively acceptable part of ageing (Steverink N, Westerhof GJ .2001). Moreover, older people recognize benefits in old age, such as increased wisdom and maturity, with opportunities for growth and lessening of demands upon them. Research has come to emphasize that ageing is highly specific to each individual, which implies that the pathway of old age is not predetermined. While growing older unavoidably entails losses, some individuals cope better with these losses than others. With this in mind, it aims to shed some light on the personal, material and social circumstances that influence how well people cope. â€Å"Successful ageing† refers to those cases where ageing people are free of (acute and chronic) diseases, do not suà ¯Ã‚ ¬Ã¢â€š ¬er from disability, are intellectually capable, possess high physical à ¯Ã‚ ¬Ã‚ tness and actively use these capacities to become engaged with others and with the society they live in. Concepts which have been used in gerntological research and which emphasize dià ¯Ã‚ ¬Ã¢â€š ¬erent aspects of the ageing process are healthy ageing (Ryà ¯Ã‚ ¬Ã¢â€š ¬, 2009) Gerontology has seen many dià ¯Ã‚ ¬Ã¢â€š ¬erent conceptions of active ageing. A classic deà ¯Ã‚ ¬Ã‚ nition of active ageing was presented by Rowe and Kahn (1997) who used the term successful ageing: â€Å"We deà ¯Ã‚ ¬Ã‚ ne successful ageing as including three main components: low probability of disease and disease-related disability, high cognitive and physical functional capacity, and active engagement with life† (Rowe Kahn, 1997, p. 433; Rowe Kahn, 1987). â€Å"Successful ageing† refers to those who are free of (acute and chronic) diseases and do not suffer from any disability, aged who are intellectually capable and those who possess high physical fitness and actively use these capacities and engage with others and the society they live in. Concepts which have been used in gerontological research and which emphasize different aspects of the ageing process are healthy ageing (Ryff, 2009), productive ageing (Morrow-Howell, Hinterlong, Sherraden, 2001), ageing well (Carmel, Morse, Torres-Gil, 2007). There is a strong normative element in the definition of successful ageing. Successful, healthy and productive ageing are evaluated as the more desirable as â€Å"normal† or even â€Å"pathological† ageing processes. Most people want to grow old without being affected by chronic illnesses and functional disabilities. Despite the efforts are to increase the proportion of healthy life expectancy, a substantial part of the old, and the very old population will have to face dependency and frailty. Hence, attention have to be paid to the fact that normative definitions of â€Å"active ageing† should not lead to the degradation and a discrimination against individuals and groups who do not reach the positive goal of â€Å"active ageing†. (Fernà ¡ndez-Ballesteros, 2008). The WHO deà ¯Ã‚ ¬Ã‚ nition of active ageing was more inclusive in respect to dià ¯Ã‚ ¬Ã¢â€š ¬erent ageing trajectories and the diverse groups of older people: â€Å"Active ageing is the process of optimizing opportunities for health and participation and security in order to enhance quality of life of aged people† (WHO, 2002) The Regional Implementation Strategy for the Madrid International Plan of Action on Ageing, the UNECE members express their commitment to enhance the social, economic, political and cultural participation of the older people and also to promote the integration of older people by encouraging their active involvement in the community and by fostering intergenerational relations (UNECE, 2002). Old age often bring decreasing functional capacity and health problems which may affect the individual’s sense of wellbeing.The goal of health for the elderly in the society may not be free from diseases but the possibility of having a good life despite of illness are in decreasing capacities (Lawton, 1991; Nordenfelt, 1991b; Sarvimaki and Stenbock-Hult, 2000). The Quality of life of the people in a developed country with chronic health condition will have a lower impact rather than the patients with the same disease in a low income country where the resources to ameliorate the disability may be scarce. The subjective and the contextual nature of Quality of life inform the World Health Organization’s definition as: â€Å"an individual’s perception of his/her position in life in the context of the culture and value systems in which he/she lives, and in relation to his/her goals, expectations, standards and concerns† (The WHO QUALITY OF LIFE Group, 1995). Thus Quality of life reflects a extended view of subjective wellbeing and life’s satisfaction that encompasses physical and mental health, material wellbeing, interpersonal relationship within and without the family, personal development, work and activities within the communities, and fulfillment and active recreation (Niemi et al., 1988). There is an important consideration in studying the factors associated with the Quality of life of the elder persons is the multi-dimensional nature of the construct and the possibility that determines from one dimension may be different from those of the other dimension. (Patel et al., 2007). NEED OF THE STUDY Little is known about factors that determine the Quality of Life of the elderly persons living in the developing societies and who are undergoing rapid social changes. Quality of life has become increasingly important as an outcome in medical research. The influence of health status is often emphasized, but other dimensions are important. In order to improve quality of life, there is a need to know what people themselves consider important to their perception of quality of life. The studies that are conducted among the groups of elderly persons have shown that Quality of life and the subjective evaluation of the life satisfaction are determined by several factors (Jakobson et al., 2007). Other than the demographic features such as age and financially status, the health, including social support functional disability and networks are often found to be important in the elderly person’s assessment of their Quality of life. (Bowling, 1994;Low and Molzahn, 2007;Richard et al., 2005 ). Other than functional impairments and the health problems to which most of the elderly persons are vulnerable (Clark and Siebens, 1993), old age may also predispose to some social and economic problems. The ccess to health care is severely limited both by manpower and paucity of health facilities and by out-of-pocket payment arrangement. Traditional family support is decreasing and social network is dwindling as migration and urbanization take the young members of the family away. Social changes are also affecting the position of the elderly in the society and leading to a reduction in their social status and influence in the community (Gureje and Oyewole, 2006). All of these factors affect the Quality of life of elderly. (Hickey et al., 2005) Quality of life is the central concepts in the ageing research. Two different traditions can be distinguished in this respect: Concepts which define quality of life in terms of objective living conditions, and concepts which define quality of life in terms of subjective evaluation (Noll, 2010). Similar distinctions have been made in the context of social gerontology. Objective quality of life can be measured by the extent to which the elderly has access and command over the relevant resources like income, health, social networks, and competencies that serve the individuals to pursue their goals and direct their living conditions. Hence, objective quality of life is high in those cases where the health is good, income is high, social networks are reliable and large and the competencies as achieved by the educational status are high. Objective quality of life can be measured by the external observers (Erikson, 1974). Subjective quality of life, in contrast, emphasizes an individual’s perceptions and evaluations. Individuals compare their (objective) living situation according to different internal standards and values. That means the elderly people with different aspiration levels may evaluate the same objective situation differently. Subjective quality of life depends upon the individual person – and lies in the â€Å"eye of the beholder† (Campbell, Converse Rodgers, 1976). Hence, high subjective quality of life can be defined as subjective well-being (high life satisfaction on, strong positive emotions like happiness, and low negative emotions like sadness). Quality of life has become increasingly important as an outcome in medical research. The influence of health status is often emphasized, but other dimensions are important. In order to improve quality of life, there is a need to know what people themselves consider important to their perception of quality of life. The study was of 141 randomly selected people aged from 67 to 99 years that formed a control sample for a study of suicide among older people. They were interviewed in person about their health, socio-demographic background and, using an open-ended question, what they considered to constitute quality of life. Their answers were grouped into eight categories. In addition, they were asked to choose from a ‘show card’ three items that they regarded as important to quality of life. Functional ability was the most frequently selected domain, followed by physical health, social relations and being able to continue to live in ones present home. It was found that socia l relations, functional ability and activities influence the quality of life of elderly people as much as health status. ( Katarina Wilhelmson ,Christina Andersson, et al., 2004) Since 1970s cardiovascular disease is the leading cause of deaths worldwide, cardiovascular mortality rates have been declined in many high-income countries Age is an important risk factor in developing cardiovascular diseases, though it usually affects the older adults. It is estimated that 87 percent of people who die of coronary heart disease are 60 and older. â€Å"It’s important that this vulnerable group of people doesn’t get overlooked so that they are properly assessed and they receive the best treatments to improve their quality of life.† Newcastle University,British Heart Foundation, (Professor Bernard Keavney, July 25, 2012) A study wasrecently carried out376heart scans calledechocardiogramson 87- 89 year olds in their homes. The results revealed that around a quarter hadundiagnosed heart problemsand are missing out on treatments, which could improve their symptoms and theirquality of life. (Newcastle University,British Heart Foundation, Professor Bernard Keavney, July 25, 2012) The purpose of the present study is to identify the effectiveness of structured teaching program on awareness of quality of life among elderly patients with cardiac disorders, at GKNM Hospital, Coimbatore. The researcher strongly believes that, the result of the proposed study can be used to enhance nursing initiatives, and to establish a teaching strategy for elderly patients attending cardiac and cardio thoracic opd’s at GKNM Hospital and thereby improve their quality of life. STATEMENT OF THE PROBLEM A Study to Assess the Effectiveness of Structured Teaching Program on the Awareness of Quality Of Life among Elderly Cardiac Patients at G.K.N.M Hospital, Coimbatore.

Wireless Vulnerabilities Threats And Countermeasures Information Technology Essay

Wireless Vulnerabilities Threats And Countermeasures Information Technology Essay Introduction to Network Security maintains its focus on the network and its vulnerabilities, protocols, and security solutions. It includes network architecture, the functions of layers in a typical network, and network based attacks including header, protocol, and authentication attacks. Bottom-up approach, it provides understanding of the vulnerabilities and mechanisms of each layer of network security. In any stadium there is network security plan in order to control all the events occurred in the stadium like ticketing selling, consumable purchases, seating arrangement and others. By using the wireless technology and mobiles we can plan the top level network security in the plan, the steps taken in this are all the members in the wireless channel have one wireless mobile. From the mobiles all the members can give the information to channel that means it is a server. All the decisions taken by the empires are by the wireless only, the video channel also very much useful in controlling the stadium. Consider the cricket stadium Chinnaswamy, Cricket Stadium in Bangalore, INDIA. The boundary line of the stadium is marked by the rope and here the boundary line is called as the perimeter of the stadium having field diameter of 140 to 160 yards. Score board has to display scores and sometimes should work as a third empire for keen observation and all this setup should work with wireless technology because wired transmission cannot be implemented over there. This stadium with a seating capacity of 55,000. Features of the stadium: The entire stadium is equipped with the very sensitive digital cameras, short and long distance explosive detectors. Totally it have 29 closed circuit television cameras, in this 29 cameras five of them are very highly sophisticated which are having the 360 degree of vision and all these will covers all the corners of the stadium. Trained marshals will operate the 29 closed circuit television cameras (CCTV), nearly 20 trained marshals are there in the stadium. These marshals having the helmets which are with sensitive cameras and sensitive detectors which are capable for covering the explosives which are happened around of 300 meter, this is called as OSD(on-screen display) camera which in the helmet and it is directly connected to the CMS(central monitoring system) vehicle. This CMS vehicle is standing outside the stadium, so whatever the marshal see and do, each and every point of the stadium and things happening in the stadium are very clearly seen in the CMS (central monitoring s ystem) vehicle. The entire system works on SNMP(simple network management protocol). Total stadium can be seen in the CMS vehicle, and another important thing is that empires decisions for example take the out and not out decisions it can be displayed on the big digital screen. The runs taken by the both the teams will be displayed on the digital screen in stadium. At the heart of the modern stadium is a communications system capable of supporting the innovative new services and applications customers are looking for. Organizing and hosting events requires a complete communications foundation essential to satisfying the communication needs of fans, guests, corporate employees, service and security staff, event organizers, press and media. It is that to provide all the components needed to build a complete, converged, secure and reliable communications system. Security, communication and services are the main aspects at the stadiums now-a- days. The organizers and event managers should be able to satisfy the complete communications foundation essential to satisfying the communication needs of fans, guests, corporate employees, service and security staff, event organizers, press and media. And also the communication system which provides all the components needed to build a complete, secure and consistent communications system. Converged IP/Ethernet Core: Stadiums support the communications needs of events with much number of users. Moreover, the supporting infrastructure is shared by different groups with different needs including stadium corporate users, media and press and event promoters. It is important to the make the event successful with High-speed, consistent and secure communication which doesnt fails. With reliable, secure, high-performance, intelligent Ethernet connectivity the enterprise LANs can intelligently prioritize real-time business communications like voice, video and multimedia services. Voice communications: Voice communications are important in any environment and mainly in the stadiums. IP networks provide the strength and quality of service that voice service requires. Converging voice and data over IP maximizes network efficiency, streamlines the architecture, reduces capital and operating costs, and opens up new service opportunities. It would be secure for organizations of all sizes to use voice over IP (VoIP), with IP PBXs (Private Branch Exchange). Today the global markets have a complete variety of IP phones, including desktop phones with displays, rugged wireless handsets, and PC-based softphones. All of these access devices operate seamlessly across the range of IP-enabled platforms and applications. Mobility: The nature of the stadium environment is mobile. Staff move constantly on making the event successful and provide the security at the top level. For the users, it is essential to have the access to key information and communication tools and allows them to roam and remain in touch no matter where they are. In WLAN IP Telephony services, we have a large choice of mobile desktops and handsets. Voice calls can be placed from laptops or PDAs(Personal Digital Assistant) using soft phones and employees can be equipped with voice over WLAN handsets that support multiple functions extremely useful for stadium staff, such as text messaging, conferencing and a push-to-talk feature that allows groups of handsets to behave as walkie-talkies. With this, the good coverage can be assured in areas which are difficult to reach with public areas. Wireless Mesh Network extends the reach of Wireless LANs securely and cost-effectively for situations where cabling for the LAN network is not in place or too costly to deploy. Implementing new Technologies With a comprehensive communications infrastructure as the base, stadiums have the foundation on which to build an intelligent environment filled with new, media-rich applications and services capable of creating new revenue opportunities and improving the overall fan experience. Wireless ticketing kiosks: Premium seats for sporting events and concerts can be expensive. Stadiums can leverage wireless technology to implement standalone, mobile kiosks that attract fans to upgrade their existing tickets for an event onsite. Digital signage directs patrons to the kiosk during the event. The fan simply inserts his ticket, checks a map of available seats, uses a touch-screen to select the new seat and inserts his credit card to pay. The machine keeps the old ticket and provides the upgrade. The stadium fills the seats closer to the action and generates revenue that would have been lost. It creates a win-win for the guest, the team and the stadium. Stadium owners can use the same kiosk to encourage customers to buy tickets for future events while guests are onsite and in the mood to buy. The kiosk can advertise upcoming events and attract fans waiting to exit after watching a game or seeing a concert. The terminal shows a list of available events and allows users to follow the same simple steps to purchase a ticket. Additionally, stadium owners can use the kiosk to capture and collect valuable information about its customer base. The kiosk can advertise loyalty programs and contests that offer incentives for fans to provide personal data that helps the stadium better understand and communicate with its audience base. Public safety and security: With thousands of people attending major events at one time, public safety and security is critical. Stadiums can leverage the communications system to offer digital security options including digital video surveillance and RFID (Radio-Frequency Identification) tagging and tracking. For example, stadiums can improve security threat detection with high-resolution IP cameras that provide full surveillance of the crowd using pre-sets by section: operators can select a stadium section and automatically receive all video from that section in multiple views. Operations staff can set rules to govern detection of left bags, perimeter entry, threshold crossing and loitering receiving alarms if any of the rules are breached Stadiums can improve event response through video feeds and text alerts that are transmitted manually or automatically to remote PDAs, laptops or offsite responders. All responders can be linked together automatically via dedicated audio conferencing channel. RFID tags can be used to locate and dispatch the closest security personnel to an emergency situation, ensuring a timely response. ABOUT NETWORK SECURITY AND TO FIND THREATS Vulnerabilities, Threats and Countermeasures Wireless networking has many advantages. Network configuration and reconfiguration is easier, faster, and less expensive. But, wireless technology creates new threats and alters the existing information security risk profile. Wireless networking alters the risks associated with various threats to security, the security objectives remain the same as with wired networks, preserving confidentiality, ensuring integrity, and maintaining availability of the information and information systems. Wireless Networks present a host of issues for network managers. Unauthorized access points, broadcasted SSIDs, unknown stations, and spoofed MAC addresses are just a few of the problems addressed in WLAN troubleshooting. Wireless Vulnerabilities, Threats and Countermeasures The wireless networks consist of four basic components: The transmission of data using radio frequencies; Access points that provide a connection to the organizational network and/or the Client devices (laptops, PDAs) and Users. Each of these components provides an avenue for attack that can result in the compromise of one or more of the three fundamental security objectives of confidentiality, integrity, and availability. Wireless Network Attacks Malicious association Malicious associations are when wireless devices can be actively made by crackers to connect to a network through their cracking laptop instead of a access point (AP). These types of laptops are known as soft APs and are created when a cracker runs some software that makes his/her wireless network card look like a legitimate access point. Once the cracker has gained access, he/she can steal passwords, launch attacks on the wired network, or plant trojans. Since wireless networks operate at the Layer 2 level, Layer 3 protections such as network authentication and virtual private networks (VPNs) offer no barrier. Wireless 802.1x authentications do help with protection but are still vulnerable to cracking. The idea behind this type of attack may not be to break into a VPN or other security measures. Most likely the cracker is just trying to take over the client at the Layer 2 level. Ad-hoc networks Ad-hoc networks can pose a security threat. Ad-hoc networks are defined as peer-topeer networks between wireless computers that do not have an access point in between them. While these types of networks usually have little protection, encryption methods can be used to provide security. Identity theft (MAC spoofing) Identity theft (or MAC spoofing) occurs when a cracker is able to listen in on network traffic and identify the MAC address of a computer with network privileges. Most wireless systems allow some kind of MAC filtering to only allow authorized computers with specific MAC IDs to gain access and utilize the network. However, a number of programs exist that have network sniffing capabilities. Combine these programs with other software that allow a computer to pretend it has any MAC address that the cracker desires, and the cracker can easily get around that hurdle. Man-in-the-middle attacks A man-in-the-middle attacker entices computers to log into a computer which is set up as a soft AP (Access Point). Once this is done, the hacker connects to a real access point through another wireless card offering a steady flow of traffic through the transparent hacking computer to the real network. The hacker can then sniff the traffic. One type of man-in-the-middle attack relies on security faults in challenge and handshake protocols to execute a de-authentication attack. This attack forces AP connected computers to drop their connections and reconnect with the crackers soft AP. Man-in-the-middle attacks are enhanced by software such as LANjack and AirJack, which automate multiple steps of the process. What once required some skill can now be done by script kiddies. Hotspots are particularly vulnerable to any attack since there is little to no security on these networks. Denial of service A Denial-of-Service attack (DoS) occurs when an attacker continually bombards a targeted AP (Access Point) or network with bogus requests, premature successful connection messages, failure messages, and/or other commands. These cause legitimate users to not be able to get on the network and may even cause the network to crash. These attacks rely on the abuse of protocols such as the Extensible Authentication Protocol (EAP). Network injection In a network injection attack, a cracker can make use of access points that are exposed to non-filtered network traffic, specifically broadcasting network traffic such as Spanning Tree (802.1D), OSPF, RIP, and HSRP. The cracker injects bogus networking re-configuration commands that affect routers, switches, and intelligent hubs. A whole network can be brought down in this manner and require rebooting or even reprogramming of all intelligent networking devices. Signal-Hiding Techniques In order to intercept wireless transmissions, attackers first need to identify and locate wireless networks. There are, however, a number of steps that organizations can take to make it more difficult to locate their wireless access points. The easiest and least costly include the following: Turning offthe service set identifier (SSID) broadcasting by wireless access points, Assign cryptic names to SSIDs, Reducing signal strength to the lowest level that still provides requisite coverage or Locating wireless access points in the interior of the building, away from windows and exterior walls. More effective, but also more costly methods for reducing or hiding signals include: Using directional antennas to constrain signal emanations within desired areas of coverage or Using of signal emanation-shielding techniques, sometimes referred to as TEMPEST, 1 to block emanation of wireless signals. Encryption The best method for protecting the confidentiality of information transmitted over wireless networks is to encrypt all wireless traffic. This is especially important for organizations subject to regulations. Securing Wireless Access Points Insecure, poorly configured wireless access points can compromise confidentiality by allowing unauthorized access to the network. Use anti-virus and anti-spyware software, and a firewall Computers on a wireless network need the same protections as any computer connected to the Internet. Install anti-virus and anti-spyware software, and keep them up-to-date. If your firewall was shipped in the off mode, turn it on. Change your routers pre-set password for administration The manufacturer of your wireless router probably assigned it a standard default password that allows you to set up and operate the router. Hackers know these default passwords, so change it to something only you know. The longer the password, the tougher it is to crack. Allow only specific computers to access your wireless network Every computer that is able to communicate with a network is assigned its own unique Media Access Control (MAC) address. Wireless routers usually have a mechanism to allow only devices with particular MAC addresses access to the network. Some hackers have mimicked MAC addresses, so dont rely on this step alone. Training and Educating Users Notice that Figure 1 also includes users as the fourth basic component of wireless networking. As is the case with wired security, users are the key component to wireless networking security. Indeed, the importance of training and educating users about secure wireless behavior cannot be overstated. To be effective, user training and education needs to be repeated periodically. The Security Policy To maintain a secured wireless network security, we need to apply these policies, so that the wireless network can be protected by the major threats and vulnerabilities. Computer Acceptable Use. A general document covering all computer use by eventstaff, including desktop, mobile, home PCs, and servers. Password. A description of the requirements for password protecting computer systems, the rules for choosing passwords, and how the password policy is enforced. Email. This policy covers the use of email sent from any email address and received at any computer system. Web. A specification of what browsers may be used, how they should be configured, and any restrictions on which sites event staff can visit. Mobile Computing and Portable Storage. A description of who owns the mobile computing and portable storage on the network, how they are supported, and what specific devices (if any) are authorized for use on the network. Remote Access. A policy stating who can access what information from which locations under what circumstances. Internet. A description of your Internet-facing gateway configuration, stating what is allowed in and out, and why. Wireless. A specification stating how wireless access will be managed on the network and how access points will be plugged in, secured, and maintained; who is allowed to use them; and under what circumstances. Servers. A statement of the standards for servers, what services are enabled or disabled by default, and important distinctions between production, test, and development environments. Incident Response Plan. No policy is complete until it also specifies what to do when defenses fail: what is considered a security incident; who gets called; who is authorized to shut things down if needed; who is responsible for enforcing applicable local laws; who speaks for the company. Standards: Workstations: Approval for workstation connection must be obtained as part of the standard workstation installation process handled by Information Technology Services, or authorized departmental technical personnel. Other devices (including, but not limited to, network components such as hubs, routers, switches, wireless access points, printers and other communication devices): Approval to connect devices other than workstations must be expressly obtained from Information Technology Services/Network Services. Vendors/visitors can obtain a physical connection access to the University network through Information Technology Services on a per visit basis. This access will be granted for a specific period of time Mail servers may not be run outside of Information Technology Services. Guidelines: Accounts Definition and use of departmental accounts and shared accounts should be restricted as much as possible. Only those functions needed by the user should be made available through such accounts. Servers 1. SSL should be implemented on Web servers if account log-in is required. 2. Run intrusion detection system where appropriate 3. Store backups offsite on a monthly basis. 4. Install firewall system where appropriate 5. Application updates must be performed every 30 days. 6. Run file integrity checker such as Tripwire daily. 7. Periodically test backups for integrity. Passwords 1. should not use any words found in dictionary of any language 2. should not use any combination of letters of a users real name, username, initials or nickname 3. should not use any combination of a famous persons name 4. should not use any combination of a spouses, girlfriends, boyfriends, or childs name 5. should not use any personalized numbers Workstations 1. Turn off workstations overnight. 2. Work-related files should be stored on the Novell cluster in the staff members home directory or the departments work directory 3. Implement periodic backups 4. Logging: a. should be enabled to record: i. successful and unsuccessful login attempts. ii. system and application errors. CONCLUSION: We introduce the top level network security plan in the stadium to control the things happening. So by this we can create the safe atmosphere to the audience in the stadium. We can prevent the things inside the stadium only but out side the stadium we cant, so the government have to come forward and give the external security to the stadium. Because of the terrorism attacks the government has to be very careful in giving the security to the stadium. For this each and every person who entering into the stadium is first checked with bomb squad and also by the wireless detector. By this we can provide the safety to people and the players in the match.

Albert Einstein :: essays research papers

What is it that triggers a spark of genius? Is there some encouragement given at the right time that starts the process or helps it along, or does genius simply find its expression despite all odds? At age five, Einstein was given a device that would stir his intellect. It was the first time he had seen a magnetic compass. He lay there shaking and twisting the odd contraption, certain he could fool it into pointing off in a new direction. But try as he might, the compass needle would always find its way back to pointing in the direction of magnetic north. Most kid at his age, including me, would have given up figuring how it worked. "A wonder," he must have thought. The invisible force that guided the compass needle was evidence to Albert that there was more to our world that meets the eye. There was "something behind things, something deeply hidden." Einstein's genius, accompanied by his logic and imagination, succeeded in continuing the work of Newton. Within the frame of the relativity theory, demanding a formulation of the laws of nature independent of the observer and emphasizing the singular role of the speed of light, gravitational effects lost their isolated position and appeared as an integral part of a general kinematics’ description, capable of verification by refined astronomical observations. Moreover, Einstein's recognition of the equivalence of mass and energy should prove an invaluable guide in the exploration of atomic phenomena. Indeed, the breadth of Einstein's views and the openness of his mind found most remarkable expression in the fact that, in the very same years when he gave a widened outlook to classical physics, he thoroughly grasped the fact that Planck's discovery of the universal quantum of action revealed an inherent limitation in such an approach. With unfailing intuition Einstein was led to the introduction of the idea of the photon as the carrier of momentum and energy in individual radiative processes. He thereby provided the starting point for the establishment of consistent quantum theoretical methods, which have made it possible to account for an immense amount of experimental evidence concerning the properties of matter, and even demanded reconsideration of our most elementary concepts. The same spirit that characterized Einstein's unique scientific achievements also marked his attitude in all human relations. Notwithstanding the increasing reverence which people everywhere felt for his attainments and character, he behaved with unchanging natural modesty and expressed himself with a subtle and charming humour.

Introduction of the Strategy :: Business, Administration

Introduction of the strategy No organization can plan in detail every aspect of its current or future actions, but all organizations can benefit from some idea of where they are heading and how they could get there. Put another way, all organizations need some strategic direction.

The Character Hester Prynne in The Scarlet Letter :: Nathaniel Hawthorne

Hester Prynne's choice to control the meaning of the scarlet letter transforms her from a shameful and evil person to a compassionate woman. Her refusal to stop wearing the letter proves the letter has a different meaning rather than adultery. Hester Prynne transforms the meaning through her good deeds and deserved redemption. After some time, society begins to construe the scarlet letter as ?Able? rather than adulteress. From this process Hester creates a passionate identity. The scarlet letter claims Hester Prynne?s past but only she can determine whether it will benefit or hurt her future. Hester Prynne sees herself as a strong and independent woman. She realizes that she has committed a sin, and therefore she refuses to remove the A from her chest. She is determined to change her identity and the Puritan community?s views. For example, Hester Prynne does not attend church, nor does she believe in a religion. She sets herself apart from everyone else and chooses to live on the outskirts of town. Hester Prynne does what she feels is right and intends to wear the A as long as she needs to, to prove she controls the meaning of the scarlet letter and not society. The Puritan community?s views of Hester Prynne change throughout the novel. The community notices that Hester Prynne is a very responsible woman and a good mother. She singularly raises Pearl and makes her own living. Moreover, she sells things to provide for her?s and Pearl?s living costs. Hester Prynne performs many good deeds, such as feeding the poor. The responsibility, independence, and good deeds help change society?s views of Hester Prynne and her scarlet letter. The effects of the scarlet letter lie in the hands of Hester Prynne.

Hebrew History Essay

Question #1 What were the major eras/events in Hebrew history? What importance do they have in Western Civilizations? Is the Bible a reasonably accurate source for the History of the Jewish people from the Egyptian captivity to the Babylonian captivity? The history of the Hebrew people is marked by war, internal conflict and an ongoing struggle for survival. Along the way, the Hebrews have crafted a rich tapestry of accomplishments through perseverance and faith. On more than one occasion, the majority of the Hebrew people have been enslaved. At other times, they were powerful and unquestioned rulers of their domain. A timeline of Jewish history shows these remarkable contrasts. The best contemporary source for the early origins of the Hebrew people is the Bible. This book contains a detailed chronology of the Hebrew people, their culture and their faith over a centuries-long time span. The first five books of the Bible comprise the Jewish Torah. These five books trace the creation of the world, its destruction by flood, the enslavement of the Jewish people, their escape, and the establishment of the nation of Israel. The thriving nation, would not last, though. It was subjugated by the Babylonians in the 700s B.C.E. In between the Egyptian and Babylon enslavements, the Hebrew people took an epic journey. According to the Bible Moses led the Israelites out of Egypt in about 1446 B.C.E. Shortly after, The Ten Commandments were given by God, laying the foundation for all future Jewish law. Thirty years after the Israelites entered Canaan, the Judges began their rule. A spectacular temple was completed in Jerusalem in about 959 B.C.E. A number of brutal wars followed in the next century. Israel itself had become a divided nation by this time. A weakened Israel had fallen captive to the Babylonians by about 586 B.C.E. The Torah is essentially a contemporary account, written by Moses and other early Jewish leaders. It spans from the creation of the world to the entry of the Hebrews into Canaan after escaping the Egyptians. The rest of the Old Testament chronicles the history of the Israeli nation, in addition to containing numerous prayers, songs, prophesies and accounts of miraculous happenings. Apart from the Biblical account, the Jewish people are mentioned in Egyptian texts dating back to 1440 B.C.E. Early Jewish history is intimately tied to the ancient Egyptian empires. Hebrew history has had a profound effect on Western Civilization. The Christian Bible, which contains the Jewish Torah along with centuries of historical accounts of Jewish culture, and is still the most widely read book in the world. Christ himself was Jewish. The Hebrews also contributed technical knowledge to the Western world. For example, the famous glassmakers of Italy were preceded by the Jewish glassmakers of ancient times. It is they who were primarily responsible for introducing this art to the world. For many, the Bible is the only credible source tracing history back to its origins. For Christians and non-Christians alike it shapes perception of the world around us. Orthodox Hebrews never accepted the Bible’s New Testament as doctrine. Instead of being the messiah, Christ is regarded as a prophet or teacher. As Christianity spread around the world, the Hebrew people were increasingly scapegoated for Christ’s death and persecuted for their rejection of him as the messiah. A deep anti-Semitism set in across Europe and spread to the new world. This has resulted in dire consequences throughout history and especially in the twentieth century. The Bible is a detailed and moving account of Jewish history. It is constructed dually as a book of history and a book of faith. Therefore, it cannot be expected to give a complete picture of all the complexities present in the development of the Hebrew nation. It is written from the perspective of a small fraction of the participants. In the following centuries scholars modified some portions of the text. Some other portions were deleted or lost. Given the lack of alternate perspectives in the Bible, it is clear that the writers and caretakers of it took extraordinary care to present and preserve the story as they believed it to be. As a result it gives us a series of signposts that, in many cases, are confirmed by other ancient texts and oral traditions. The details will always be a matter of individual perception, but the Bible does provide a relatively accurate road map to the history of these extraordinary people. The most critical event in the history of Judaism is their deliverance from four hundred years of slavery to the Egyptian Pharaoh. According to the Bible, Moses and his brother Aaron were chosen to lead the Hebrew people on this miraculous escape. After several plagues were put upon the Egyptian people the Pharaoh was finally convinced to let the people go. He soon changed his mind, but the Red Sea swallowed up the Egyptian army as they tried to pursue the Hebrews. The Hebrew tribes lived in the desert for forty years until God allowed them to enter the promised land of Canaan. While the Hebrews were in the desert many of the Jewish rites and traditions were created that are still practiced today. Entering Canaan would not be easy, however. The Israelites waged war and defeated many of the tribes already living in the area. The land was divided into twelve subsections, one for each of the twelve tribes of Israel. Hundreds of years of wars and in-fighting followed as the nation of Israel tried to establish itself. Archaeological evidence found in recent years seems to confirm many events related in the Bible. The evidence also raises more questions, however. Archaeology and modern science has its limitations. Many of the major events in the Bible are backed up by modern evidence. It is more difficult to ascertain why and how these events happened. Question #2 In what way were the economic foundations of the Roman and the Han empires similar? How do you account for the similarity? How were they different? What were the consequences of the differences? During the Han dynasty, the Chinese economy underwent substantial changes. At the beginning of the period the economy was primarily based on subsistence farming. Trading activity was minimal and most farms were small family-run operations. Later in this period, a more substantial trade network emerged. A peasant class somewhat dependent on trade markets became more widespread. Grain and rice were the primary crops of the region. They were often used to pay for other goods and services. Rice crops were particularly robust as farmers constantly improved their farming methods. A trend toward commercialization of these products characterized this period. Industry also began to emerge during this period. Inventors, so prolific during the early part of the dynasty, began to lag behind their counterparts on other continents during the late part of the dynasty. The expansion of trade networks also dried up. The caused an economic vulnerability that enemies would effectively exploit. The Roman Empire became an economic powerhouse based essentially on its continual conquest of new areas. Eventually, this strength would become weaknesses. The Roman economy had several different weaknesses that played a role in the ultimate collapse of the empire. The Roman Empire economy specialized in luxury goods, architecture and infrastructure, and creating war-related materiel’. In pre-conquest times the Roman economy was much smaller, but it was also better balanced. Farms surrounded and supplied a central city-state where merchants, tradesmen and a professional class worked. The expansion of the empire forced the Romans to adopt a new monetary system based on both silver and gold. The availability of these metals varied causing the value of each in relation to the other to change frequently. This creation caused confusion and a lack of full faith in the monetary system in the years when the empire was expanding most rapidly. This, in turn, set the table for further difficulties down the road. As the empire became less centralized the cost of maintaining it rose consistently. Meanwhile income revenues were less dependable and predictable. Emperors began to rely heavily on slave labor and taxation to support the empire. Defending the widespread empire entailed enormous costs. Over time the empire became stretched too thin. In a desperate effort to remain financially viable, the Roman emperors reduced the actual content of silver and gold within their coinage. In other words, the face value of the coins was more than they were actually worth. The creation of a widely practiced monetary system allowed the economy to diversify and innovate. When the monetary system became less reliable the opposite began to occur. Due to slave labor, heavy taxation and other factors, economic innovation in Rome ground to a halt. The Romans could no longer afford to arm and equip their vast army. Far-flung outposts of Roman power became increasingly vulnerable. The â€Å"barbarians† from northern Europe were eventually able to penetrate the heart of the Roman Empire. Essentially, the Roman Empire operated an early example of free market capitalism. Their version of capitalism had several flaws that ultimately led to its destruction. Free market capitalism on this scale would not emerge again for many centuries. The fates of the Roman and Han empires exposed an ironic fact about economics and national security. When trade with outside entities peaked, so did the relative power of the empires. On the other hand, when trade was cut off or simply dried up, the empires were exposed to great risk. Their fates also showed the vulnerability of economies based in a large part on slave labor. In the Roman Empire, slaves were acquired from conquered territories and made to do much of the work that kept the empire operating smoothly. In the Han dynasty, people actually sold themselves and their families into slavery. Slave labor is inherently inefficient. Even for those who willingly sold themselves into slavery, production levels are rarely as great as that of free workers. Both economies eventually frowned on the use of slavery in such a widespread way, but economic stagnation had already set in. Both empires might be viewed as examples of the dangers of over-expansion. This is especially true of the Romans, who primarily relied on their war gains to support their economy. When the pace of conquest slowed, so did the economy. The Han dynasty differs in its initial focus on subsistence farming before converting to a more consumer-based economy. Both economies had their strong and weak points, but the Roman economy was particularly vulnerable to collapse. Question #3 What effects did the Indian Ocean trade have on the societies that took part in it? How is trade related to the dissemination of technology? Define the term â€Å"Africanity† and explain the development of â€Å"Africanity† in terms of Bantu migrations. Ancient Indian Ocean trade not only introduced new goods to various societies; it also began a centuries-long spread of information, technology, religion, language and culture. Trade across the Indian Ocean was well-established at least two thousand years ago. Cities sprung up along the African and Middle Eastern coasts. In this time port cities were primarily isolated from inland areas, meaning that the coastal cities developed unique identities of their own. Kinship and trade among the coastal cities in different regions led to a â€Å"de-nationalization† of these peoples. A sailor was a sailor first, and the citizen of a specific regime second. These sailors often married women in far away points. The wives, in effect, served as bridges between cultures. Generally speaking, using sea routes for trading was much less expensive than moving goods over land. Also overland routes were often blocked or impeded by armed forces or bandits. As Indian Ocean ship building improved, what resulted was an ancient version of globalism. The cross-cultural social and economic effects we see today were present in antiquity on a smaller scale. The relatively vast distances necessary to travel the Indian Ocean gave rise to new techniques and methods in shipbuilding. These methods were diffused across cultures along with improvements in tools, farming methods and other technologies. Ships were capable of transporting goods farther than ever before. There is strong evidence of an ancient trade triangle between Southern Africa, Egypt and India. There is also evidence that early traders ventured as far as Java in the Far East. As today, not everybody in ancient times was content with these cross-cultural influences. As the Islamic empire grew, an increasing number of Africans became affected by their influence. Some were content with this and other outside influences. Others may not have been. In about 1000 B.C.E. the first of several large migrations began. â€Å"Africanity† is a term of identity for the African people. It is distinctly different and less clearly defined than identifiers for other cultures. In fact, African languages have no one specific word for â€Å"identity†. In our language identity refers to an independent individual with clear boundaries from other individuals. In Africa, identity is more complex. Instead of being a static identifier, â€Å"Africanity† refers to an ongoing process of finding one’s identity within the larger culture. There is no singular identity. One’s identity is always being formed and is dependent on interaction with others. Africanity also is expressed discovering one’s differences from others. It is also a come to be a term of resistance to the imposed definitions of identity from the Europeans and others. Africans are not so comfortably identified in terms of a geographic description as Europeans or Americans might be. Identity is a process rather than a label. The Bantu are a large group of Africans loosely defined by language and tribal connections. In several large waves, the Bantu migrated throughout Africa. They diffused their language, culture and technological developments while also absorbing characteristics of the people they came into contact with. The Bantu migrated primarily from north to south over about 1500 years. Their possible reasons were numerous and still somewhat mysterious. Overpopulation and the lack of arable land for agriculture are often cites as reasons for this tremendous population shift. Others have proposed more primal reasons. Were the Bantu migrations an expression of â€Å"Africanity†? Some Bantu were moving away from attacks by outside empires. More pervasive were the encroaching cultural and religious influences that some Bantu may have felt were drawing them away from their own pursuit of identity and forcing outside standards upon them. There is still a lot of debate as to why such a large number of Bantu migrated throughut Africa in successive waves. It may have been strictly economic or there may have been deeper elements involved. Whatever their reason; their integration and diffusion of other African societies and their knack for survival are in their own ways expressions of Africanity. Question #5 Discuss the origins of Islam, and the development of the religion of Islam, the umma, and the three branches of Islam (Sunni, Shiite, and Kharijite). What were the causes of the decline of the caliphate? The faith of Islam is thousands of years old. It traces its history to many of the same characters mentioned in the Bible and the Torah. For instance, Abraham is a central figure in all three texts. Islam would go on to take unique perspectives and characteristics from the other two, partially due to regional differences. As individual religions became the main defining characteristic of competing nation states, wars in the name of religion became commonplace. The primary figure in the development of Islam was the prophet Mohammed. He was born approximately 570 B.C. in the town of Mecca (in modern day Saudi Arabia). He rejected the polytheism commonly practiced around him in favor of one God, called Allah. In his 40s, Mohammed began receiving divine revelations which he dutifully recorded for posterity. These revelations formed the central part of the Qu’ran, the book of faith for the religion of Islam. Lacking acceptance from his peers, and from Jewish and Christian critics, Mohammed moved his ministry to the city of Medina. From Mohamed’s time all the way to the present day differing views on the Qu’ran have caused conflict within the Muslim world. There is a very strict constructionist view of the book that demands adherence to the book’s tenets even when taken to extreme levels. On the other side a more moderate wing of Islamic leaders who believe that contact and cooperation with the non-Islamic world is not living in violation of the Qu’ran. After Mohammed’s death, there was no clear successor to his leadership. Various local sects competed for this leadership with three main groups emerging – Sunni, Shiite and Kharijite. To this day the three groups have doctrinal differences that sometimes result in bitter conflicts. Each group claims a different line of succession tracing all the way back to Mohammed himself. For instance, the Shi’a believe that the legitimate line of leadership must run directly through the family of Mohammed, while the Sunni and others believe that leadership can be politically elected from outside Mohammed’s family tree. During Mohammed’s life the influence of Islam remained primarily within the Arabian Peninsula. Shortly after his death Islamic armies began to conquer nearby regions, eventually reaching Western Europe and Israel. Early Islam also promoted the acquisition of scientific knowledge. As a result, early Islamic society was highly advanced. The Umma is a term that describes a wide variety of Islamic people. It includes Islamic people in all primary spheres of Islamic influence. Most commonly, the Umma refers to all Islamic peoples from Africa to the easternmost point of Pakistan. The term dates back to ancient Islam. The centralization of the Islamic governmental structure lasted about 200 years. By the end of this period powerful emirs began to rule individual kingdoms within the empire. Control by a centralized caliphate was proving to be impractical and unresponsive to the defensive needs of certain localized areas. Eminent scholars argued increasingly that the security of the Umma was at risk under the caliphate system. Many leaders wanted to maintain the caliphate while also delegating more day-to-day management to local authorities. This idea gradually began to take hold. Meanwhile, waves of Turkish and Selijug and other immigrants helped accelerate the process toward local emirates. Economic and security factors eroded the Caliphate and gave rise to a network of smaller emirates.
