Generally most sluice gates are closed and opened by a mechanical winch, a winch using an oil-pressure, or a winch mixing both. Because of their size and structure, they should be safely operated with more than two pulling devices helping each other. At the moment of their opening and closing, there usually occur some additional loads to the structure which cannot be exactly measurable at the stage of designing. Such additional loads can cause the sluice gate to be unbalanced and make it hard to open and close the gate, and by also overloading a winch, they can inflict a significant damage to the safety of the sluice gate. This paper explains a FDC(Force-Displacement Control) system which simultaneously considered the oil-pressure and displacement in order to evenly distribute the force and make a winch balanced at the opening and closing motion. This FDC system was implemented by means of the PID(Proportional Integral Derivative) function of XG 5000 program. It was experimented on a model of the sluice gate winch with the hydraulic oil pressure cylinder. The experiments showed that the developed FDC system made the winch of hydraulic oil pressure cylinder open and close cooperatively in spite of various external loads. Therefore the FDC system is proven effective when it is applied to a winch of sluice gate.

This study was a descriptive study to investigate factors affecting quality of life in the Korean elders with diabetes mellitus. A secondary data analysis was conducted using the data of "The Fourth Korea National Health and Nutrition Examination Survey, 2008." The survey included 9774 adults aged over 64 years with diabetes mellitus and 226 samples were used for this study. Data analysis was conducted using SPSS 12.0 program and descriptive statistics, Pearson's correlations, and multiple regression analyses were performed. Correlation analysis showed that quality of life was associated with the amount of alcohol intake, the level of stress awareness, walking time, and suicidal thoughts. The amount of alcohol intake, the level of stress awareness, walking time, and suicidal thoughts accounted for 34.5% of quality of life. These findings suggest that nursing researchers need to consider age, suicidal thoughts, and drinking as important factors affecting quality of life of Korean elders with diabetes mellitus and nursing intervention focusing on the issues needs to be developed.

Objectives: The purposes of this study were to investigate CHPs' knowledge, attitude, and practice regarding UI, and to identify predictors of their UI related practice. Methods: A descriptive-correlational study using self-administered questionnaire was conducted. A total of 330 members of the local Korean Association of CHPs were included in this study. A mailed survey was conducted to collect data. Findings: Of CHPs surveyed, 170(51.5%) returned completed questionnaire. Educational preparation of CHPs regarding UI was limited. The mean correct score of knowledge scale was 68.96%. Overall, CHPs exhibited positive attitudes toward UI. CHPs in this study were not actively participate UI related practice. Contrary to expectation, knowledge was not significantly related to CHPs' practice regarding UI. In the final analysis, CHPs' practice regarding UI was predicted by attitude toward the care of UI clients and educational needs for UI and these two variables explained 9% of variance of UI related practice. Conclusion: The results of this study suggest the importance of attitude and educational needs in shaping UI related practice among CHPs. To facilitate UI related practice among CHPs, efforts for attitudinal change related to UI among CHPs are needed. Moreover, continuing educational program for UI management should be developed, applied and evaluated.

Recently it has been encouraged in developed countries that labor force participation of the elderly is one of the means to cut down the cost of social welfare for them. However, empirical studies have rarely explored how work in later life contributes to national economy. Especially, even though 56.6 percent of elderly workers aged 65 and older engaged in agriculture and forestry in Korea, their contribution has been socio-economically overlooked. This study aims at examining the effect of farming labor in later life on social welfare expenditure. For this purpose, social welfare expenditure was defined as social benefits provided for the elderly by the social security in public sector and measured as transportation allowance, pension, livelihood aid, medical aid, and health insurance in 2003. Data were obtained from National Health Insurance Cooperation and 37 town/village offices and analyzed by 3 age groups; 65~74, 75~84, and 85 and over using SPSS/PC windows program. Results showed that both livelihood and medical support in all age groups were expended more to non-farm than to farm workers. The amount differences per person between them were 113,959~361,132 won in livelihood support and 15,644~51,418 won in medical support. Also, participation in farming influence reduction of livelihood expenditure for the group 65~74 and 75~84 and that of medical expenditure only for the group 65~74. Based on these results, it was estimated the amount of social welfare expenditure reduced by farming labor in later life. The limit of this study and the policy implications of the results are discussed.

This study examined the factors affecting forms of long-term care service use by elderly and the forms of use are classified facility care service, home care service, and unused. It is used data from the 2nd pilot program for the Long Term Care Insurance scheme and it is analysed 5,497 cases. Multi-nominal regression is used. According to the results, women use formal service more than man do, and wowen use facility care than home care. Those who eligible for National Basic Livelihood Security System(NBLSS) are shown to have higher use of formal care(especially facility care) than the middle income class, and the low income class than the middle income class has lower use of formal care. In addition, higher the family care is available, lower the taking part in the service. The big cities and mid sized cities than rural are used the formal service and moreover mid sized cities are used facility care than home care. Furthermore, the level of care need is determinants of service use and function of ADL, IADL, and abnormal behavior is also determinants of formal service(especially facility care). But nursing need and rehabilitation need are not determinants of formal service use. Based on the results, the recommendations are developed and implemented for the improvement the elderly long-term care insurance.

Studying abroad in and of itself should be a unique and transformational learning experience for university students. Too often, "study abroad" is a code word for "faculty vacation" or "easy credit hours". For an international learning experience to be truly transformational it must offer an intense and directed program that maximizes the time the student spends in the accumulation of information that is new or different from what the student has "learned" previously. "Study abroad" may be a misnomer because it is not only about studying in another country or culture, that is, taking courses that usually have an attendance time of a few hours a week, but it is also about living in another country which becomes a 24/7 learning experience. Providing these programs during the Covid-19 pandemic has been a keen opportunity for institutional learning. When this immersion in foreign culture is combined with academic rigor applied to a student's chosen field of study the growth can be exponential. So, what is the relationship between academic and personal growth? The National Association for Study Abroad has found that "students who have studied abroad are better able to work with people from other countries, understand the complexity of global issues, and have greater intercultural learning. One study found that students returned from their study abroad experiences more tolerant and less fearful of other countries, but with a greater sense of nationalism-a phenomenon they called 'enlightened nationalism'." It is often said that "you only really learn to appreciate things that are important to you when they are gone, when you miss them." The international learning environment can provide this opportunity. The restrictions on various societies in the past two years due to the international Covid pandemic have provided existing study abroad programs with a true testing ground for the validity of their programs. At the end of the day, American colleges and universities are not helpless in the face of these developments. A lot depends on how a university positions itself for a future based on the uncertainties of the past. As Winston Churchill was working to form the United Nations after WWII, he famously said, "Never let a good crisis go to waste". In another context, Churchill's insight on human nature can also be applied to the coming semesters and years as studying abroad rebounds. What new strategies will be developed and maintained? Institutional commitment without fear will be necessary to assure that "studying abroad" will continue to develop as a truly unique and transformational learning experience.

Edification in Daesoonjinrihoe is not only a phenomenon that occurs following the differences of religious experience or spiritual development among the community members, which enables the members to share teaching and learning experiences with one another, but also an issue determined as one of the major activities of the religious order and a plan for achieving the purpose of the religious order-Podeokchenha(Wordly Propagation), Gujechansaeng (Salvation of all mankind) and Jisangcheonguk Geonseol(Building of earthly paradise). The purpose of this article is to clarify its concept and provide an example of edification, through considering the historical model for edification to help the cultivators with their work of edification. The archetype of edification of Daesoonjinrihoe was formed and gradually developed in phases by Sangje, Kang Jeungsan, the Supreme God(姜甑山, 1871-1909), Doju, Jo Jeongsan(趙鼎山, 1895-1958) and Dojeon, Park Wudang(朴牛堂, 1917-1995), by the three of whom the Religious Authority was succeeded. Sangje descended to the human world and preached to people to live by the rule of Haewon Sangsaeng(Resolution of grievances for the mutual beneficences of all life) and set an example of abolishing the old customs, living in mutual beneficences and having respect for human being. Doju, in revering the last will of Sangje, established the religious order by setting its creed, rituals and activities, which formed most contents of the archetype of edification. Dojeon set up a religious faith system by firmly establishing the Religious Authority and performed the True Law in accordance with Sangje's program of heaven to educate the cultivators to achieve the goal of self-cultivation following the last will of Doju. Through this, a perfect method to reach the state of Dotong(The Truly Unified State of Dao) is fulfilled. In this way, the archetype of edification was formed in the process of succession of Religious Authority. In conclusion, edification in Daesoonjinrihoe contributes to a 'systematic conveyance and understanding' through the historical archetype of edification, and it can be described as a concept that becomes a model to put into practice the 'True Law' of teachings given by two Sangjes for Dotong. Therefore, edification of Daesoonjinrihoe is drawing attention of its development as an important activity that realizes the ultimate value of the religious order because it solves the problems of immorality(absence of Dao), disorder and disregard of human value generated from the other side of this material civilization, with the truth of Haewon Sangsaeng, and has a function of rebuilding and leading the individuals and the society to the Truly Unified State of Dao through performing of the True Law.
