This study was performed to investigate the relationships among bone mineral densities (BMD), anthropometric data and lifestyle factors in the elderly. Subjects included 138 elderly (male: 38, female: 100) aged over 65 years, who were home-(dwelling in a low-income area of Puchon City. The BMDs of the lumbar spines (LS), femoral necks (FN), Ward′s triangles (WT) and trochanters (TC) were measured by dual energy X-ray absorptiometry. The females showed significantly lower BMDs in four sites (p < 0.0001) . The elderly aged over 75 revealed significantly more decreased femoral BMDs than the elderly aged 65 to 74. Female with BMIs of 20 to 25, showed significantly higher BMDs in LS, FN and trochanter than those with BMIs of less than 20. However, males displayed significantly higher BMDs in only LS with increasing BMIs. THe BMDs of LS correlated with weights (r = 0.543, p < 0.001), heights (r = 0.477, p < 0.001), upper arm circumferences (r=0.368, p < 0.01), waist circumferences (r=0.367, p < 0.001), subscapular skinfold thicknesses (r=0.363, p < 0.001) and flip circumferences (r=0.231, p < 0.01). Non-smokers and non-drinkers shelved significantly higher BMDs in trochanters only in the case of the males. Female milk-drinkers showed significantly elevated LS BMDs. Eighteen percent of the males were assessed as having osteoporosis, as compared to fifty percent of the females. Ninety-three percent of the females and 81.6% of the males responded that they often or always had "difficulty in standing for a long time".

Our country has depended on fossil fuel very much according to the Increasing of the demand of the electric power. For instance, if the reduction and freezing caused by the warm gas in earth by the regulation of international environment happen in Korea it will bring about the result of weakness in industrial activity. As a result, it will cause many problems to compete an advanced country which wants to connect environment with the activity of industrial product in their country. The photovoltaic system outputs have peak about a half past 13 o'clock(before and after) mainly in a good weather. The output decreases rapidly from a half past 17 o'clock and PV output doesn't work at six o'clock before the sun rises. The outputs of PV system stops at that time. The frequent degree of harmonics in dwelling house which lots of people live has peak from 19 o'clock to 22 o'clock Harmonics mainly happens at least at night. In recent, many researches about power quality has been studying very hard in order to solve the question, the voltage fluctuating and harmonics as one compensator. In this paper, I suggest the algorithm which can increase the power quality as a rate of operation of this system. This algorithm proves to have effectiveness through computer simulation.

Since 1960's there have been conducted quite numbers of origin and destination (0-D) surveys in Korea, Most of them, however, were to be said not so successful. In this paper, it was investigated that why the previous 0-D surveys were failed, and that how it could be improved. The findings of this study are: 1. The collection of sample data itself was performed relatively well, but the problem was in the improper expansion methods which were applied. 2. To improve the expansion methods, it should be performed not only the dwelling unit-based sample surveys but also commercial vehicle survey, cordon line survey, screen line counts and other auxiliary travel surveys like transit patronage survey, vehicle miles survey etc. at the same time. 3. To expand the sample surveyed data in a proper way, the adjustment factors should take a disaggregate form and also should be applied not to the specific trips, but to the specific trip makers to avoid the bias which could be caused by the application of adjustment factors in a way that has been used previously. 4. If there is no considerable change in travel patterns, we can synthesize the present 0-D data with past surveyed sample data, using present statistic data in the same way which was developed in this paper when expanding and adjusting sample data.

Purpose: The purpose of the present study was to identify prevalence of excessive daytime sleepiness(EDS) and its associations with sleep habits, sleep problems, depression, subjective health status and obesity in community dwelling adults. Method: Data was collected from adults aged 20-59 years by random sampling. Subjects completed a questionnaire which was composed of the Epworth Sleepiness Scale, Center for Epidemiologic Studies Depression Scale, and questions that included items about sleep habits, sleep problems, subjective health status and sociodemographic characteristics. Height and weight were measured for calculation of body mass index. The statistical analyses was based on 3,302 adults (51.5% males and 48.5% females). Descriptive statistics, univariate logistic regression and multiple logistic regression were used. Result: The prevalence of EDS was 17.1% Multiple logistic regression showed that the associated factors of EDS were depression, obesity, dissatisfaction with sleep time, irregular sleep, and habitual snoring. Depression was the most significant associated factor(adjusted odds ratio for severe depression=2.27, 95% Confidence Interval=1.73-2.96). Conclusion: EDS is a common symptom in adults. Our finding suggested that persons with a complaint of EDS should be completely assessed for depression and obesity as well as sleep problems.

Purpose: This study was to examine the effect of electrical muscle stimulation therapy on chronic knee pain and depression for the aged. Method: Design was one-group pretest-posttest design. Samples were 32 elderly of 60 years old and above with chronic knee pain and depression. Measures were the S-F McGill Pain Questuionnaire for chronic knee pain and the Korean Elderly Depression Scale for depression. Electrical muscle stimulation therapy, experimental treatment, was applied for 12 weeks, 3 times/week, 15 min/time. Data were collected from January 2005 to May 2005. Data were analyzed using SPSS PC+ 12 version. Results: After receiving electrical muscle stimulation therapy, chronic knee pain (t=-88.034, P=.000) and depression (t=-114.659, P=.000) were significantly decreased. Conclusion: Electrical muscle stimulation therapy can be a better effective primary nursing intervention on chronic knee pain and depression for community dwelling elders.

In the domestic housing market, uncompleted lot-solid apartments and unoccupied residences are increasing in the medium-large scale area whose rents and transactions have been unstable, as going through the financial crisis and economical recession. Demands for small-scale housings are steadily increasing by practical consumer group who don't need large places, which are often not needed for the current people who are spending most of their time outside of their houses. Therefore, this study proposes the useful methods for spatial planning for small-scale houses for multiple households, including variable form, levels form, multi-level form, and smart-sizing. For efficient spatial planning for that purpose, here, small-scale housings are not limited to places for families with 1-2 members, but considered as one of broader approaches to graft various households and families. In addition, we examined the existed trends of researches about spatial utility of small-scale places, and did the research about the status of small-scale housing developments, and then proposed the direction for future small-scale housings by analyzing the advanced examples.

Recently housing demands are going to be diversified, and many suggestions are driven for the housing consumer's right of choice and expectation for welfare services. These require the policy change from the clear division between houses and facilities toward more market-oriented concept capable of mixed-use development of houses with facilities. The research explores the possibilities to provide various types of mixed-use developments of houses and facilities in the level of architectural design and political implication. Major case studies focus on the elderly welfare housing with serviced residence with the comparison of similar cases in Japan. The policy implications are, first, expanding the production of elderly housing with more elderly care services, second, challenging time-sharing residence composed of serviced residence and small dwelling units, third, activating the production of small scale housing development with small public facilities. The simulation shows the merits and demerits of this concepts and the efficacy of the policy implications.

The numerous changes made during the Japanese colonial rule became the basis of the current housing in Korea. Therefore, in order to understand the modern Korean housing, it is essential to understand what the Korean traditional life styles admitted or changed, and how the foreign culture of that time influenced the Korean housing under the Japanese colonial rule. Content analysis through literature review was utilized for the study, and specific sources were research papers, books, magazines, newspapers, and novels. The period during the Japanese invasion was the most active era of modernization in the Korean history. For the housing culture, especially, it can be considered as the most significant period that accepted new housing cultures that replaced the old traditional housing. The Japanese and the Western styles of housing were introduced, new materials and collective production methods were used, and the symbol of the current urban housing in Korea, multi-family dwelling, was constructed. In conclusion, the Koreans did not directly use the Japanese and western housing culture, which were constructed during the Japanese colonial period. They were adapted and altered into Korean style, and eventually, produced various eclectic housing styles.

Steven Holl is outstanding architect who has been applied his phenomenological thinking to his works. he has been reported that he had adhered to focus his interest on coherent phenomenological theme and sublimated his architectural concept succesfully. This study focuses on relationship how phenomenological concept has common ground with architectural parts and with the study on phenomenological application methodology of architectonics of Steven Holl. In the case of Holl, with the theme of sense and flesh, he molds phenomenologically sensitive space. His works contains coherent phenomenolgical concepts such as distrust of rationality, synthesis of consciousness, and qeustions of perception. The Methodologies of connection with environment(nature or bridge), regional values, placeness, light and time are considered in his works(books and architectural works) as anchoring, interwining and parallax for phenomenological process in his concepts. His methodologies of enlisted works contain many valuable concepts of phenomenological intuition and would be applicable to contemporary and future architecture for humanism.
