In the super-aged societies, an increased elderly population living in solitude has been causing many problems. Since the elderly may incur a sense of loss and interest in suicide when living alone, this study investigated the effects of smartphones as well as types of living arrangements on elderly peoples' sense of loss and suicidal thoughts. This study found social roles and relationships were lower for older individuals using smartphones than those using 2G phones. Not surprisingly, those living with family members or a partner had significantly fewer suicidal thoughts than those living in solitude. However, our results indicate subjects' loss of role and relationships was affected more significantly by their smartphone usage (2G phone vs. smartphone) rather than their living arrangements (i.e., living with family or a partner vs. living in solitude). Moreover, smartphone users showed a lower sense of loss in terms of social roles and relationships. Among the elderly, loss of health, social role, and relationships were identified as precedents for increased suicidal thoughts; yet, economic capacity was surprisingly not an indicator of suicidal thoughts.

This study analyzed the current status of care policies and senior citizen issues in Korea, which has entered a super-aging society, and attempted to suggest improvement measures for desirable convergence policies. The problems of the elderly in Korea have emerged as health problems, poverty problems, loss of roles, and care problems due to changes in the concept of family, values, and socioeconomic structure. In addition, poor seniors need jobs and employment policies, and healthy middle-class seniors need policy development to enable leisure activities and volunteer activities. In particular, it is necessary to establish policies to enable people to spend the rest of their lives in elderly care facilities and elderly care hospitals through community care policies. The super-aging society accounts for more than 20% of the total population among those aged 65 or older, and according to the National Statistical Office, it is expected to become a super-aging society by 2025. Elderly welfare policies must provide various programs and the needs and services of elderly care, and in the future, a super-aging society will need to secure a lot of financial resources and maintain a productive population to cover the financial resources. In other words, the human life cycle is from birth to death, and when the ratio of natural deaths of the elderly and infants born is appropriate, the society and the country can be seen as stable, vibrant, and healthy societies.

현재 국내 하천에는 수많은 보가 존재하고 있으며, 하천에 설치된 보는 보 주변 지역에 많은 혜택을 제공한다. 보의 규모가 클 경우 소수력 발전을 위한 용도로 사용되거나, 선박 통행을 위한 수심 확보 목적으로 활용된다. 상수원으로서 농업용수와 생활용수를 공급하며, 홍수 시 상부 저수지를 홍수 조절을 위한 목적으로 활용되며, 지역 주민들에게 여가 활용의 기회를 제공한다. 이렇듯 하천에 설치되어 있는 보는 유용한 역할을 수행하지만 사용하고자 하는 용도가 없어지고, 노후화되어 보의 기능이 점차 약화되는 보들이 하천에 계속 남아있게 된다면, 필요 없이 하천을 막아 흐름을 정체시켜 결국 환경이나 생태적인 측면에서 커다란 손실을 가져오게 된다. 최근 농경지 도시화, 경작 방식의 변화, 취수시설물 통폐합, 시설 노후화 등으로 매년 수십 개 이상의 보가 폐기되고 있으나, 폐기된 보는 대부분 철거되지 않고 하천에 남아 여전히 문제를 발생시키고 있으며, 외국의 경우에는 이미 기능 및 용도를 상실한 보 철거는 하천 생태통로 복원 등의 목적을 위해 하천환경복원의 한 방법으로 널리 활용하고 있다. 특히 보의 기능 상실 여부는 단순한 시설물 노후 여부로 따지는 것이 아니라 본래의 기능을 상실하였을 경우에는 시설물이 노후화되지 않았더라도 적극적으로 철거하고 있다. 본 연구는 보 철거를 통한 하천생태통로 복원 기술 개발을 위한 연구의 일환으로 기능을 상실한 보 철거를 위한 보 철거 선정 체계에 대한 시안을 제시하고자 한다. 철거 대상 보 선정을 위해서는 보 관리주체 및 보 주변지역에 거주하는 주민의 역할이 중요하며, 이에 따라 보 철거 선정 체계는 보 철거를 위해서 보 주변 지역 거주민을 설득하며, 하천의 환경 개선을 위한 합리적인 대안 제시를 목적으로 하고 있다. 선정 체계를 바탕으로 주민 협의 및 대안 제시를 통해 결정된 대상 보는 선정 체계 안에서 보 철거 영향 판단 절차에 따라서 보 철거로 인한 수문, 수리, 지형, 수질, 생태 영향을 판단하게 되며, 이와 더불어 사회 경제적인 영향을 평가하게 된다. 평가결과에 따라서 보를 완전히 철거하거나 다른 대안을 고려하여 보를 부분적으로 철거하거나 개량하게 된다.

최근 경제적 어려움이나 극심한 스트레스로 인해 자살이라는 극단적인 선택을 하는 사람들이 늘고 있다. 우리나라는 5분에 한명씩 자살을 시도하고, 45분에 한명씩 자살로 생명을 잃을 만큼 자살 문제가 심각하다. 우리나라는 2006년에 이미 OECD(경제협력개발기구) 국가 중 가장 높은 자살율을 기록하고 있으며 2009년 통계청 자료에 의하면 인구 10만 명당 31명에 이른다. 특별히 경제난으로 고통 받고 있는 사람들에게 자살분위기가 도미노처럼 번져 나가고 있는 것은 참으로 우려스러운 일이 아닐 수 없다. 인간생명의 존엄성이 상실되어 가는 현실사회의 문제를 떠맡아 기초적인 실마리를 제공하고 해결해야 하는 것은 세상의 빛과 소금의 역할을 해야 하는 교회의 몫이라고 보여 진다.

The purposes of this study were: (a) to examine the relationship between parental/occupational role reconstruction and psychological well-being in middle and old age, (b) to investigate the psychological factors to affect parental/occupational roles reconstruction. The role reconstruction was measured as the extent to obsess with parental and occupational role in transition. Mail survey was conducted on 378 Japanese married men and women in ages between 50 and 69. As results, the hypothetical pathway was identified in women as follows. The obsession with parental and occupational roles raised parental and occupational role loss anxiety. And both of role loss anxiety lower psychological well-being. For men, obsessed with the occupational role was significantly influenced by autonomy, gender role attitude, social support network. For women, gender role attitude significantly influenced on occupational and parental role obsession, and social support networks had significant impact on parental role obsession. Results of this study were discussed in terms of the importance of role reconstruction in middle and old age, gender difference in role reconstruction according to gender role socialization.

ICT education guidelines revised in 2005 reinforce computer science elements such as algorithm, data structure, and programming covering all schools. It means that goal of computer education is improving problem-solving abilities not using of commercial software. So this paper suggests problem-solving method of maze escape through robots' cooperation in an effort of learning these elements. Problems robots should solve are first-search and role-exchange. First-search problem is that first robot searches maze and send informations about maze to the second robot in real time. Role-exchange problem is that first robot searches maze, but loses its function at any point. At this time second robot takes a role of first robot and performs first robot's missions to the end. To solve these two problems, it goes through four steps; problem analysis, algorithm description, flowchart and programming. Additional effects of our suggestion are chance of cooperation among students and use of queue in data structure. Further researches are use of more generalized mazes, application to real field and a talented curriculum.

In this paper we propose a new method of security visualization, VisFlow, using traffic flows to solve the problems of existing traffic flows based visualization techniques that were a loss of end-to-end semantics of communication, reflection problem by symmetrical address coordinates space, and intuitive loss problem in mass of traffic. VisFlow, a simple and effective security visualization interface, can do a real-time analysis and monitoring the situation in the managed network with visualizing a variety of network behavior not seen in the individual traffic data that can be shaped into patterns. This is a way to increase the intuitiveness and usability by identifying the role of nodes and by visualizing the highlighted or simplified information based on their importance in 2D/3D space. In addition, it monitor the network security situation as a way to increase the informational effectively using the asymmetrical connecting line based on IP addresses between pairs of nodes. Administrator can do a real-time analysis and monitoring the situation in the managed network using VisFlow, it makes to effectively investigate the massive traffic data and is easy to intuitively understand the entire network situation.

This study examines the roles of government and reasons of defeat on 9.11 terror, iraq war between 2001 and 2003. The administration functions critical role of national security. And punctual, accurate information supply capability helps policymaker's decision-making. Hence, information of punctuality and accuracy should be given to policymakers. And without two above written factors, it will result in failing. Information concoction on policymaker's pressure, biased informant, inaccurate information and lack of assembly means under the extensive organization and technologized spying means, Fail to keep information objectivity, leads to information failure. In the context of a series of facts, we shall cover the position of government and reasons of calamities. Two incidents deem as information failure by national security service, but concoction of Iraqi mass destruction weaponry is believed as bush administration's deception on account of political gains. For fully functional government role, governing body should reinforce all aspects of gathering, analyzing, and making use of information more objectively in the first place. In particular, information concoction involving policymakers post massive stumbling block to organized outcome. The thesis presents a prospective view of government position under the U.S. secret agent over 9.11 terror and Iraq war.
