In order to solve housing shortage, an apartment has been built and supplied in large quantities in Korea. As such a result, the apartment became a typical housing type in Korea. However, the housing became vulnerable to accommodate rapidly changing life-style & life-cycle of koreans and was lost the concept of Korean traditional housing for inheriting and developing Korean traditional culture. Therefore, this paper aims at eliciting of design elements for development on standard model of long-life housing with durability & flexibility based on data derived from housing consumers's questionnaire survey and expert's opinion surveys. We expect that the standard model developed on the basis of open building applying support & infill elements will be used as a standard model for planning future long-life housing with capacity.

This study is a part of research for developing the technologies of long life pavements having more than 40-year design life. The objective of this study is to develop the simplified design procedure for determining the layer thickness and modulus of the long life pavement. A synthetic database was established using the finite element program of a pavement structure with various combinations of layer thickness and modulus. The synthetic database includes the structural and material information, surface deflection, and critical pavement responses. Using the developed synthetic database, this paper suggests the minimum layer thickness and modulus for long life pavements bared on the limited strain level concept. Results demonstrate that the pavement greater than 410mm of total AC layer thickness is considered as the long life pavements regardless of the material characteristics and thickness in each layer. To become a long life pavement, a total thickness of AC layer should be greater than 250mm. The design procedure for determining the layer thickness and modulus of the pavements with AC layer thickness ranging from 250 to 410mm is also presented in this paper.

The purpose of this study was to investigate the correlation between ethical dilemma, end-of-life care stress and burnout of the nurses in long term care hospitals and descriptive correlations to identify factors affecting burnout. The subjects of study were 143 nurses who are working in the seven long-term-care hospitals in G-do and had more than one experience of end-of-life nursing care, understood the research items and agreed to participate in the research. In this study, it was founded that end-of-life care stress, age, job position, and end-of-life care education were found to be influential factors affecting burnout of the nurses in long-term care hospitals. As a result, age and occupation, end - of - life nursing education, and end - of - life stress were found to be factors affecting nurses' burnout. Therefore, in order to prevent and alleviate burnout of long-term care hospital nurses, a systematic intervention program that manages stress related to end-of-life nursing care is needed.

A long life is the desire of many people. The purpose of this study was to describe the thoughts that are held by elderly people about long life as the elderly are approaching the end of life. The research was conducted using an ethnographic method to add understanding to this subject. The field work for this study was done from July, 1991 to August, 1993 in third phases in Chun Buk province. The results of the present study show the following : The thoughts of the elderly about chang su showed three important concepts : In Myoung Sae Chun(lived as life), Su Cheuk Dah Yok(long life is a disgraces, and Transcendence of life: In Myoung Sae Chun showed the thought of limitation of man’s life and realistic thought about the life through free oneself from death and life. Su Cheuk Dah Yok meant experience of physical difficulty, experience of sons and daughter’s death ahead one’s own self. Senility was the most afraid problem for the elderly. Transcendence of life showed pursuit of a continuing life through connected with sons and the family. The conditions promoting chang su were described as clear water, fresh air, adequate eating, deep sleeping, gender(female). In addition it showed that ecological and environmental conditions (heavy work, starvation, vegetable food, physical environment, respection for the elderly). These results showed that the elderly was recognized one’s own self as living being rather than adhered to the life, and will promote understanding the elderly’s desire for long life. Also, suggested to nursing practice that should maintain self-esteem and respect for the elderly, Therefore, these results can be used nursing practice for the elderly.

The purpose of this study was to estimate the shelf-life of Ssanghwa-tang by long-term storage test. Experiments were conducted to evaluate the stability such as the selected physicochemical, pH, identification, heavy metal, microbiological experiment under a long-term storage test of Ssanghwa-tang. The significant change was not showed in pH, heavy metal, microbiological, identification test and quantitative analysis based on long-term storage test. The contents of albiflorin, paeoniflorin, cinnamic acid, liquiritin, and glycyrrhizin in long-term storage test were 66.8-93.1 ${\mu}g/mL$, 429.0-495.0 ${\mu}g/mL$, 3.8-4.4 ${\mu}g/mL$, 32.0-38.1 ${\mu}g/mL$, and 66.8-71.7 ${\mu}g/mL$, respectively. Shelf-lifes by 5 compounds about 3 lots at room temperature were predicted 21-37, 14-21, and 16-72 months, respectively. The suggested shelf-life would be helpful on the storage and distribution of herbal medicine.

This study suggests long-life asphalt pavement method which can save maintenance cost by increasing the design and performance period of pavements. The high modulus asphalt binder developed and then various physical tests are performed. Laboratory performance tests and accelerated pavement test are conducted for the high modulus and conventional mixtures. The test results show that dynamic modulus values of high modulus mixtures are higher than those of the conventional mixtures, The high modulus mixtures yield better fatigue, rutting and moisture damage performance than conventional mixtures. Structural analysis is performed and a database is built up for long life asphalt pavement design. Pavement response model is developed through a multiple regression analysis program, SPSS using the database. A design software for the long life pavements is developed based on the pavement response model and laboratory and field performance tests results. In addition, optimum pavement sections and materials are suggested. The suggested AC thickness of long life asphalt pavement is 29cm. A Life cycle cost analysis(LCCA) is conducted to check the economical efficiency of the long life pavement section. The LCCA result shows that initial construction costs of long life and conventional pavements are almost equal, but long life pavement is more profitable in terms of the LCCA.
