  • Estimating loss rates with the packet traces captured from some point in the middle of the network has received much attention within the research community. Meanwhile, existing intermediate-point methods like [1] require the capturing system to capture all the TCP traffic that crosses the border of an access network (typically Gigabit network) destined to or coming from the Internet. However, limited to the performance of current hardware and software, capturing network traffic in a Gigabit environment is still a challenging task. The uncaptured packets will affect the total number of captured packets and the estimated number of packet losses, which eventually affects the accuracy of the estimated loss rate. Therefore, to obtain more accurate loss rate, a method of strengthening packet loss measurement from the network intermediate point is proposed in this paper. Through constructing a series of heuristic rules and leveraging the binomial distribution principle, the proposed method realizes the compensation for the estimated loss rate. Also, experiment results show that although there is no increase in the proportion of accurate estimates, the compensation makes the majority of estimates closer to the accurate ones.

  • This is a descriptive study that introduces programs that support family caregivers looking after the elderly, by focusing on the case of Georgia, in the United States. The U.S. is one of the few countries that support family caregivers by law. In this study, we focus on the evidence-based interventions implemented through the Alzheimer's Disease Supportive Services Program (ADSSP), a federal policy that complements the National Family Caregiver Support Program (NFCSP). Our findings show that one-on-one evidence-based programs (EBPs) for family caregivers are both economical and effective in assisting caregivers. In our discussion, we highlight how the implementation of the latest EBPs can build an infrastructure to support family caregivers. ADSSP funding is useful as it constructs a caregiver support through the implementation of programs in the local community. The result is the creation of a well-coordinated division of labor among government agencies, academia and NGOs, which produces a synergetic effect in funding, research and development, translation and implementation of programs, and staff training. We conclude that the implementation of EBPs funded by the government is a useful reference for Korea and other rapidly aging countries, if we are to create an infrastructure for caregiver support, which can effectively prevent a crisis in caregiving.

  • Web 2.0 has become the face next generation Web among the business world and research community. Web 2.0 is instant superficial gratification of people. On the other hand, Semantic Web is deep, meaningful and lasting relationship with data. So, it is difficult to apply the Semantic Web to the real world. In this paper, a platform for educational services using the Semantic Web and Web 2.0 is proposed. The proposed platform is based mix of the Semantic Web and Web 2.0, so it is useful to apply in the real world applications. Two services are presented, one is a semantic email system and the other is a cyber study space. The cyber study space adjusted each student is presented. The study environment is called iStudySpace that has personal scheduler, study status plan table, personalized search engine and several gadgets. Finally characteristics and limitations of the Semantic Web and Web 2.0, the organization and components of the platform, evaluation of iStudySpace are shown.

  • The network community provides people a new area which is called a cyber area, not physical area. However, today in the cyber area, the negative function has been causing social problem. In fact, it has not been causing by original function. Specifically speaking, main reason why it's leading to the negative function is that teenagers are logging into inappropriate sites (such as: violent, adult sites) to unnecessary sites (such as: e-mails with unknown signs combined with words, inappropriate language used in certain web board). Not only that, private password and ID's are being used by unknown user to accomplish illegal access. If this problem does not get solved through immediate development of technologies method, the cyber crime will increase in short period of time. The purpose of this paper is to understand each analyzed method which can cope with negative internet function, to discuss suitable management in certain web board an to check with fuzzy intercommunication mood.

  • This study is a qualitative study applied with in-depth interviews and phenomenological analysis. The objective of this study was finding out the function of the elder protection agency by interpreting the meaning developed from the experience of the workers about the role of the elder protective service agency. As a result of the analysis, the essential themes were 'Struggling and working hard', 'Obstacles that cannot be lifted', and 'Reaching the time to be reborn as an organization for the elderly human rights.' The common essence of these themes is 'The road to human rights orientation: a destination that must be reached, though not easy to go.' In order for the meanings to be settled and to fit in to the community, it was suggested it is a situation in which both internal and external renewal of the institution for the protection of the elderly is most needed. In addition, much as it turned out that legal and institutional support must be provided so that the elder protection agency can be reborn as human rights organizations with more professionalism, it was proposed to follow the institutional improvement plan derived from this study.

  • This study aimed to explore the factors explaining the safety of disabled women in the convergence society and was surveyed 374 disabled women nationwide. This study examined the factors that explain the safety of disabled women from the accidents and crimes in terms of individual, familial, and community characteristics. Main findings are as follows: 1) the safety from accident was largely explained by the community type and social capital condition in characteristics of community domain. The material hardship in characteristics of familial domain and disability level in characteristics of individual domain explained the safety from accident also. 2) the safety from crime was largely explained by the material hardship in characteristics of familial domain. And the community type and social support condition in characteristics of community domain and the educational level in characteristics of individual domain explained the safety from crime. Based on the findings, we suggested practical and institutional implications to ensure the disabled women's safety.

  • There have been many previous studies about an effect of anonymity on self control behavior. However the previous studies are on the aspect of results such as the usefulness, the problems of cyber crime or a lack of trust by anonymity. This study identifies the accurate definition of the objective technical anonymity and subjective social anonymity. And it reveals the relationship among technical anonymity, social anonymity, community tie, and self control as an effect of anonymity. The result of survey shows that technical anonymity affects self control through social anonymity and the relationship between technical and social anonymity is affected by community tie. This study presents how the anonymity affects individual behaviors. So it can be used as a reference to the policy on anonymity of the internet.
