With the rapid aging of the nation's population and the increasing number of elderly people with difficulties in daily life, the elderly care system was implemented for social solidarity. Structural problems in the long-term care system that emerged after the introduction of the system are demanded, and the problem of functional readjustment between nursing hospitals and facilities is raised due to the lack of continuity of care for the elderly by institutional and salary types. In this study, we set up research problems related to personnel, staff, and services to address the problem and conducted FGI. Research has shown that the number of elderly and recognized people in the region, the number of elderly and elderly patients, needs to be reflected in long-term care demand, the direction of appropriate institutional and manpower supply policies, and the establishment of local government goals and plans to strengthen the long-care institutions. It was revealed that non-medical accident arbitration bodies are needed to apply the cost of food insurance, provide programs through links with relevant institutions, and manage the admission smoothly.

With the recent development of IT technology, research and interest in various bio-signal measuring devices are increasing. But studies related to ECG(electrocardiogram), which is one of the most representative bio-signals, particularly arrhythmic signal detection, are incomplete. Since arrhythmia has various causes and has a poor prognosis after onset, preventive treatment through early diagnosis is best. However, the 24-hour Holter electrocardiogram, a tool for diagnosing arrhythmia, has disadvantages in the limitation of use time, difficulty in analyzing motion artifact due to daily life, and the user's real-time alarm function in danger. In this study, an ECG and pulse monitoring device capable of continuous measurement for a long time, a real-time monitoring app, and software for analysis were developed, and the trend of the measured values was confirmed. In future studies, research on derivation of quantitative results of ECG signal measurement analysis is required, and further research on the development of an arrhythmic signal detection algorithm based on this is required.

Objectives : The purpose of this study is to investigate the minor stress in daily life related to undergoing hemodialysis and the relationship between minor stresses, coping skills, and subjective quality of life among the patients with end stage renal disease. Methods : Seventy seven patients on hemodialysis were enrolled in this study. Minor stress was assessed with daily stress inventory-Korean version(K-DSI), ways of coping checklist identified the use of the following coping strategies:problem-focused, seek social support, emotion-focused coping and wishful thinking. Socio-demographic data were obtained and World Health Organization-Quality of Life Scale(brief form) was also administered to subjects. Results : Participants mean age was $55.92{\pm}13.71$ years. The mean of the event, impact and impact/event (I/E) ratio scores of K-DSI were $29.06{\pm}21.57$, $88.69{\pm}75.88$ and $2.92{\pm}1.11$, respectively. These scores were much higher than normative data of K-DSI. Among the 5 categories of this inventory, the scores of cognitive stressors were highest. 5 categories of the inventory showed positive relationship with way of coping subscales, which showed coefficient of correlation between 0.259(p<.01) and 0.495(p<.001). However, no significant correlation was found between minor stress subscales and quality of life. Hemodialysis patients in our study used more emotional-focused coping methods, which was considered as passive way of cope than problem-orientated coping methods. Conclusion : The main findings of this study indicated that patients on hemodialysis showed higher level of perceived minor stress than normal population. The patients treated with hemodialysis tend to use passive way of coping primarily. For assessing the stress in patients on hemodialysis, clinician has to consider both level of perceived minor stress and the ways of coping the patients primarily use.

Objective : This study was designed to identify the effects on the time usage and quality of life of seniors with stroke by applying lifestyle redesign programs on the theoretical basis of the Occupational Balance. Method : A pretest-posttest control group design was conducted for a total of 40 stroke elderly people living in nursing homes(20 experimental and 20 control groups). Prior assessment was conducted for two weeks before the application of the lifestyle redesign program. For the next 10 weeks, the lifestyle redesign program was applied seven times a week. After that, a week of post-evaluation was conducted. The time usage for the subjects was analyzed by Life Time Survey Table of the National Statistical Office(2009) and life quality for them was analyzed by World Health Organization Quality of Life-BRIEF (WHOQOL-BRIEF). Result : The comparison of time usage before and after application of the program demonstrated that for the experimental group, rest and sleep(t=-4.89, p<.001), and leisure(t=-4.67, p<.00b1) showed significant differences. In addition, intergroup comparison results showed that there were also significant differences in rest and sleep(t=-2.24, p<.01) and leisure(t=3.57, p<.01). The comparison of life quality showed a significant difference between two groups(t=6.80, p<.001). If you look at the sub-area of quality of life, a significant difference was identified in physical health(t=6.08, p<.001), psychological health(t=5.21, p<.001), living environment area(t=3.60, p<.01). Conclusion : Lifestyle redesign program actually reduced the time usage for rest and sleep for elderly with stroke living in nursing homes, and increased the time for participating in leisure life resulting in improved quality of life.

Today, the emergence of cyberspace and advancement of globalization caused not only the transformation of our productive and conventional life but also the revolutionary transition of use of destructive violence such as crime and warfare. This transition of environmental condition connects various security threats which separatedly existed in individual, local, national, and global levels in the past, and transformed the mechanical sum of all levels of security threats into the organic sum of multi-dimensional security threats. This article proposes that the sum of multi-dimensional security threats is caused by the interconnectivity of various different levels of security threats and the integrated interdisciplinary perspective is essential to properly understand the fundamental existence of today's security problem and the reality of fear that we face today. The holistic security, the concept proposed here, is to suggest the mode of networked response to multi-dimensional security threats. The holistic security is suggested to overcome the conventional divisional approach based on the principle of "division of labor" and bureaucratic principles, which means more concretely that national security and criminal justice are divided and intelligence, military, police, prosecution, fire-fighting, private security, and etc. are strictly separated into its own expertise and turf. Also, this article introduces integrated security approaches tried by international organization and major countries overseas with the respect of the holistic security. The author have spent some substantial experience of participant observation, meetings, seminar, conference, and expert interviews regarding the issues discussed in the article in various countries including the United States, Russia, Austria, Germany, Canada, Mexico, Israel, and Uzbekistan for the last ten years. Intelligence and information on various levels of security threats and security approaches introduced in this paper is obtained from such opportunities.

COVID-19 is threatening the safety of ships and seafarers by delaying seafarer rotation. Shipping companies and governments have a blindspot in case of the onboard environment of seafarers. An effective, alternative plan should be devised to eliminate the possibility of human accidents in an emergency that threatens the safety of seafarers. According to the survey of former and current seafarers, the most important factor in boarding life was safety, and the most necessary thing during emergencies was to secure smooth seafarer rotation rather than improve wages and welfare. By analyzing the major routes of national shipping companies by continent, ports with a large number of calls and a high Air Connectivity Index were selected as the base port. In addition, the route was designed for effective, domestic seafarer rotation during international shipping. Other countries must be consulted to establish a travel route linking ships, ports, and airports for the safe return of sailors to their home countries during an emergency. In addition, it is necessary to work together for the seafarers who are in trouble of seafarer rotation through cooperation with the International Maritime Organization(IMO). Starting with this, the government should have a monitoring system for the return and non-return routes as well as the number of seafarers on board. If such a system is established, it will be able to determine the response direction of our country's policy in case of an emergency. Along with the shipping company's ef orts to improve the treatment of seafarers, national and social attention will be needed to review domestic laws and improve awareness about seafarers.
