The purpose of this study was to assess the level of quality of life and related factors among the elderly in Korea. In particular, we focused on factors affecting the quality of life of the elderly in long term care. We used the third Korean National Health and Nutrition Examination Surveys (KNHANES) from 2005. We sampled a total of 3,571 (10.5%) elderly from the national survey. We compared the mean of quality of life to socioeconomic status, Activities of Daily Living (ADL), health behavior, and disease variables. We used EuroQol-5D among KNHANES to assess the quality of life. In this study, the mean score of the quality of life among the elderly was 2.57. Logistic regression showed that the elderly who were male, with spouses, with health insurance, and with good ADL levels enjoyed higher quality of life scores and odds ratios than those who were female, divorced, uninsured, and with low ADL levels (p<.05). The quality of life of the elderly was affected by socioeconomic, ADL, health behavior and disease variables. To improve long term care and the quality of life among the elderly, we need detailed research to clarify the effects of these factors.

Grade 91 steel is used for the major structural components of Generation-IV reactor systems such as a very high temperature reactor (VHTR) and sodium-cooled fast reactor (SFR). Since these structures are designed for up to 60 years at elevated temperatures, the prediction of long-term creep life is very important to determine an allowable design stress of elevated temperature structural component. In this study, a large body of creep rupture data was collected through world-wide literature surveys, and using these data, the long-term creep life was predicted in terms of three methods: Larson-Miller (L-M), Manson-Haferd (M-H) and Wilshire methods. The results for each method was compared using the standard deviation of error. The L-M method was overestimated in the longer time of a low stress. The Wilshire method was superior agreement in the long-term life prediction to the L-M and M-H methods.

In Korea, there has been a tendency that multi-family housings are constructed by providers such as constructors or real estate agents for the economical benefits and selling efficiency, using standardized plans, load-bearing wall system, water-based construction method, and uniformized formworks. Especially, the traditional installation works which service equipments are buried into structures cause serious problems such as shortening building life span, increasing times of remodeling during specific period (100 years) and wasting resources. Also the unilateral way of massive distribution by providers for multi-family housings is not appropriate to meet the various social needs of residents. To solve these problems, it is necessary to build long-life housing which can be easily separated installations, interior and exterior finishings from structural parts. Therefore, this paper will examine the present administrative law and the civil law in order to find negative factors that can be obstructions for providing long-life housings and set the direction to revise the regulations.

Purpose: This study was a descriptive study to identify factors affecting the attitude toward life-sustaining treatment of nurses working at long-term care hospitals. Methods: Data were collected through structured questionnaires from August 2nd to 27th, 2019. Study participants consisted of 163 nurses who were working for at least 6 months from 7 long-term care hospitals in B and K city. Data were analyzed using t-test, ANOVA, Scheffe' test, Pearson's correlation coefficients, and hierarchical regression with SPSS WIN v 21.0. Results: There were significantly positive correlations between awareness of good death (r=.46, p<.001) and perception of patients' rights (r=.32, p<.001). The factors affecting participants' attitude toward life-sustaining treatment were awareness of good death (β=.35, p<.001) and their own view of death (β=.24, p=.001), which explained about 27.0% of the attitude toward life-sustaining treatment. Conclusion: Based on these results, it is necessary to develop nursing educational materials that can establish values for deaths, and cultivate legal and ethical knowledge related to attitude toward life-sustaining treatment. In addition, since the severity of a patient's condition varies and the characteristics of the institution vary depending on the type of hospital, a study is needed on the relevance of variables considering the hospital environment.

Most of the Korean multi-dwelling houses have less than 20 years of lifespan. Because the environmental issues such as energy consumption, limited resources, and demolition waste problems became been more and more critical, we now need to focus on long lasting and adaptable buildings. Korean wall bearing apartment buildings are constructed with site cast concrete for core, exterior, and interior together with pipes varied, so when the buildings are old and life style of the users changes, it is difficult to maintain and renovate these buildings. In this study, to resolve the problems described above, two types of Korean long life multi-dwelling housing models which represent improved durability and adaptability responding user's needs and life style changes were proposed with various methods as follows: Either column and beam structure or flat slab structure was used to utilize space better. To make maintenance easier and renovation economical for both public space and each unit, plumbing pipes, ducts, and conduits were clustered at the cores and public corridors with access doors and light weight partitions with steel studs and raised floors or above-ceiling spaces were used in lieu of site cast concrete walls and floor slabs with varied pipes.

As the life expectancy increases resulting in the aged society, the post-retirement life became one of the most important concerns of people. The long-term investment vehicles such as retirement savings and pension plans have been introduced to meet such demand of society. This paper examines the impact of asset allocation strategies on the long-term investment performance. Because of the unusually long investment horizon and the compounding effect, a suboptimal asset mix in a retirement plan can be a very costly and irreversible mistake. Instead of relying on anecdotal evidence to evaluate the merits of different allocation strategies, this paper performs various tests including stochastic dominance tests using both actual data and Monte Carlo simulated data that best fit the historical experience. The results indicate 1) the long-term investments perform better than the short-term investments, 2) the optimal asset allocation strategy for the long-term investments should be highly equity dominated.

The thesis is a comparative analysis of Infill Technologies between Korea's long-life Mock-up House, a study driven by 'Durability and Flexibility of Long-life Housing Technology Development' of R&D, and Japan's KSI experimental house, the major example of Japan's long-llfe housing. In terms of the domestic Mock-up House, a system of building the floor first was applied. The floor material of each housing unit required a development of dry heating component that is partially substitutable in order to avoid conflict with the finishing. Also, a development of a floor system that can counteract against the construction inaccuracy was required. In the Case of an outer wall, need to make the wall with the chassis. In the case of ceiling, need to develop the double ceiling system which is good for sound insulation. Also, in comparison to KSI experimental house in Japan, it would require to develop a wiring system of the ceiling which can react to the movement of the wall. Especially, to assure the flexible nature of an internal wall, it would desperately require the research and development of the products related to components and flexible system of mechanical/electrical/communication parts as well as supporting institutionalized system for this development. Furthermore, for KSI experimental house in Japan, it would be necessary to formulate a construction manual as well as a systematic and practical planning guide to invent a new interface rule which will secure simplicity of assembling, dismantling, installation and replacement of architectural components for which research development is quite insignificant at the moment. This effort will have to continue to give a solid direction for better application of such reference manual during construction and development of long life span apartment by public sector as well as private corporations.
