This study was conducted to evaluate the accuracy of the official death registry in rural area. The base data used for the study was 379 deaths registered during the period of 1993 and 1994 in 4 rural townships of Chonnam province. The interview survey for cause-of-death was performed on the next of kin and/or neighbor. Additional medical informations were collected from hospitals and medical insurance associations for the purpose of verification. The underlying cause-of-death of 278 cases presumed by the survey was compared to the cause on official death registry. There was a prominent disagreement of cause-of-death between the survey data and the registry data(agreement rate: $38.9\sim44.6%$, according to disease classification method). These results may be caused by extremely low rates of physicians' certification, which were mostly confined to the poisoning and injury. Symptoms, signs, and ill defined conditions on death registry could be classified into circulatory disease(32.3%), neoplasm(21.2%), digestive disease(7.1%), injury and poisoning(7.1%) and so on. These results suggest that careful attention and verification be required on utilization of death registry data in rural area.

In 1992, the first design standard of quake proof bridge was established. However, most bridge structures which were constructed without considering earthquake in former times need performance of quakeproof property. Quakeproof analysis in current bridges, is based on analysis of load base which just has strength over the load of simple structures but is not checked through simple comparison of strength performance of structures so that we would like to check that ADRS method is reasonable or not using ADRS method(Accleration-Displacement Response Spectrum Method), a analysis method based on displacement of object of performance test. As the result of that, the capacity spectrum method can avoid complex dynamic analysis in analysis based on loads and it efficiently applies to design verification with normal checking for quakeproof performance and aimed performance of new structures. However we can not consider effects of high modes and it has problem that does not consider falling of performance in structures by repeated load.

Purpose : The purpose of this study was to investigate the effectiveness of pain release through the four weeks aquatic exercise among the female subjects aged above 50 and who suffered from arthritis. Methods : The assessment was validated by blood analysis which measured the fluctuations of Erythrocyte sedimentation rate(ESR), C-reactive protein(CRP) and Rheumatoid factor(RF). Among the 50 subjects of this experiment, the control group has only taken a regular treatment from the clinic and the other experimental group has done aquatic exercise. The experimental group has practiced the aquatic exercise 50 minutes a day for one month excluding the weekends. Results : Blood analysis revealed that ESR was decreased in both the control group and the experimental group and the major effect of CRP was diminished only in the experimental group. No significance of RF was found in both the control group and the experimental group. Conclusion : These results indicate that the aquatic exercise is an effective treatment for arthritis that is compatible with the similar results from the previous studies. In line with this, the aquatic exercise program can provide an effective treatment and control of the disease with the arthritis patient. Accordingly, the regular basis aquatic exercise proved to be quite satisfactory treatment in this regard and we contend that it is vital for the arthritis patients.

The goal of this paper is to analyze the Freedom Center Apacle in Seoul designed by Kin Soo Geun who was a leading architect in Korean Modern architecture. Freedom Center was built in 1963, that was the largest monumental building to support military regime during cold war period in Korea. This paper deals with historical background of construction of Freedom Center and its characteristics compared to similar monumental buildings, especially Corbusier's Chandigar and Kenzo Tange's Hiroshima Peace Center. The Monumentality in Freedom Center came from the reference to these two buildings and its site plan. This paper tried to show how similar the layout of buildings between the Freedom Center and Peace Center. The origin of the sublime aura in Tange's linear layout of Peace Center is from Japanese Famous Shrine(Jinku). Kim translated it to serve the ideological purpose to protect from socialist regime in the name of freedom. Its over-scaled roof and weak contents showed Freedom center was a kind of theaterical setting belong to formalist building. But in spite of its symbolic and representational gesture its also had a architectonic physical quality to make it a monument. The change and duration in time testified the autonomous power of architecture in Freedom Center. Freedom Center was also important for using the exposed concrete and its superior finish. It was influenced not from western way of Benton Brut which was usually called New Brutalism but Japanese way of treating expose concrete. In spite of its limits Freedom center achieved new trend and sensibility in Korean Modern Architecture.

Cohousing is based on collaborative network, or fictive kin in the community. It could facilitate the goal of self-sufficiency. This research aims to investigate the motivation of move to cohousing communities in Sweden, and to find out if there are any significant differences according to two different cohousing types; between the +40 cohousing and the mixed-age cohousing. The +40 cohousing is a kind of senior cohousing in which residents are supposed to be aged over 40. Questionnaire survey was applied and 242 collected data were analyzed by SPSS statistical program. Notable differences in demographic and dwelling variables are found between the 2 groups. There are more women, singles, academics, and small dwellings in the +40 cohousing than in the mixed-age cohousing. Referring motivation of move, "sharing common activity" and "idea of cohousing" are commonly noticed as the main reasons why people move to cohousing communities. Major difference between the 2 groups is that residents of the +40 cohousing tend to stress more on social interaction with neighbors than practical merit. On the contrary, ones of the mixed-age cohousing focus more on practical advantage than social interaction. As a conclusion, it is evident that motivation of move to cohousing communities is different by cohousing types, which have different residents' characteristics. Cohousing could contribute to elevate marginal group's quality of life as an alternative living environment. Therefore, cohousing design has to be tailored to adapt residents' specific needs of different life-stages. In order to implement cohousing model into other countries, for instance into Korea, it needs to experiment with the notion of transplanting selected cohousing principles to a public housing development. In the mixed-age cohousing where more dual income families with young children than conventional housing developments reside, residents would need more practical advantage than emotional support in the community, while as residents in the senior cohousing need vice versa.

Background: Most of the epidemiology studies on the effects of sun exposure and prostate cancer were conducted among the temperate countries of North America and Europe. Little is known about the influence on Asian populations. The purpose of current study was to evaluate any association of sun exposure with risk of prostate cancer in Chinese, Malays and Indians who reside in the tropics. Methods: The Singapore Prostate Cancer Study is a hospital-based case-control study of 240 prostate cancer incident cases and 268 controls conducted in Singapore between April 2007 and May 2009. Detailed information on outdoor activities in the sun, skin colour, sun sensitivity and other possible risk factors were collected in personal interviews. Cases were further classified by Gleason scores and TNM staging. Odds ratios (OR) and 95% confidence intervals (CI) were calculated using unconditional logistic regression analysis, adjusted for age, ethnicity, education, family history of any cancers, BMI and skin colour. Results: We found that prostate cancer risk was increased in subjects with black/dark-brown eyes (OR 5.88, 95%CI 3.17-10.9), darker skin colour e.g. tan/dark brown/black (OR 7.62, 95%CI 3.41-17.0), frequent sunburn in lifetime (OR 4.30, 95%CI 1.7-11.2) and increased general sun exposure in adulthood per week (OR 2.03, 95%CI 1.09-3.81). The increased risk was consistent for high grade tumours and advanced stage prostate cancers. Conclusion: The findings from this study suggest that excessive sun exposure is a risk factor for prostate cancer in Asians.

Background: Colorectal cancer (CRC) is an important cause of mortality and morbidity in many communities worldwide. This population based study was conducted to assess determinants of colorectal mortality in Iranian patients. Materials and Methods: A cohort of 1,127 cases of confirmed colorectal cancer registered in a population based registry covering 10 referral hospital in Tehran, Iran, were followed for five years. Information about tumor characteristics, smoking status and family history were collected at base line and survival status were followed every six months by contacting patient or next of kin (if patients died during the follow-up). The cause of death for each case was validated by verbal autopsy and referring to patient medical records at the time of death. The data were analyzed by Stata software using univariate and multivariate analysis (Cox regression). In building the model a p value of less than 5% was considered as significant. Results: The age at diagnosis was $53.5{\pm}14$ years. Sixty one percent were male. Colorectal mortality among the patients was 96.9 person-years among men and 83 person-years among women. Seventy five percent of patients lived for 2.72 years, 50% for 5.83, and 25% for 13 years after the diagnosis of colorectal cancer. The age at diagnosis was significantly different between men and women (p<0.03). Higher tumor grade predicted higher death rate; the adjusted hazard ratios were 1.79 (95%CI, 0.88-3.61), 2.16 (95%CI, 1.07-4.37), and 3.1 (95%CI, 1.51-6.34) for grades II, III, and IV respectively when they were compared with grade I as reference. Ethnicity, marital status, family history of cancer, and smoking were related to survival with different degrees of magnitude. Conclusions: Among many factors related to survival among the colorectal patients, tumor grade and smoking showed the highest magnitudes of association.

Physiological analysis of swimming in 13 (age:16.3 years, freestyle swimming) and 15 (age:17.2 years, breast stroke swimming) high school boys through oxygen uptake and oxygen debt measurements were performed. The following results were obtained. 1. In freestyle swimming oxygen debt was greater and mechanical efficiency was lower in subjects with less speed. In beginner efficiency was only 1.35%, whereas, in a more skilled subject it ranged to 4.28%. The mean efficiency was 2.59%. 2. In freestyle swimming the speed-oxygen debt curve was convex to the speed axis and the curve shifted to the right the more the speed was greater. 3. Maximal oxygen uptake in breast stroke swimming was 2.51 l/min or 41.8 ml/kin/kg and was 79.3% of treadmill running. Maximal pulmonary ventilation in breast stroke swimming was 73.1 l/min and was 87% of treadmill running. Maximal ventilation equivalent was 2.89 liters. 4. In subjects with greater speed of breast stroke swimming maximal oxygen uptake and mechanical efficiency of swimming were greater. The mechanical efficiency of breast stroke swimming averaged 1.08% $(range:0.51{\sim}1.70%)$. The coefficient of correlation between speed and efficiency was r=.87.

This paper examines the history of Korean names, focusing on the structural characteristics and the literal meanings of those for kings and ordinary people. Roughly speaking, the Korean surname system traces its source to China. Historical records show that the Chinese were already using their family names around 1000 B.C. After a millennium or so, the Korean began to follow suit. Initially, however, surnames were in regular use among kings and their kin only: it was not until the late Shilla dynasty, around A.D. 800, that the commoners began to have Heir surnames. And yet, surnames still tended to be limited to men of noble birth, until around A.D. 1000. Though the Korean surname system may be said to have its origin in Chinese, there are no lack of native surnames that have as long a history, e.g., Hae, Bak, Sok, Sol, Ul, and Ol. Typical surnames of Chinese origin that are found during the late Shilla dynasty, around A.D. 900, include Jang (as in Jang Bogo) and Choi (as in Choi Chiwon). Unlike those of Chinese origin, typical Korean names during the age of Three Nations tended to allude to nature or natural phenomena, as can be witnessed in Bit 'light,' Balgum 'bright,' Nuri 'world,' and Soidori where soi means 'steel' and dol 'stone,' Other surnames abound that have to do with river, stream, field, prairie, and so on. King Muryong's original name was Sama, a variant of som 'island,' indicating where he was born. A person skilled in archery was called Jumong or Hwalbo. Baembo was so called because he 'crawls like a snake, baem,' In these last two examples, bo, as well as its variant bu, functions as a suffix, and is also found in Cochilbu, Isabu, Babo, Nolbu, Hungbu, etc. The tradition of using this kind of native Korean names has gradually disappeared, giving place to the names of Chinese style-although very recently we see an on-going movement toward using native names.

Based on social capital theory, this study intends to understand accessed and mobilized social capital of married women with young children and the difference between two types of social capital in terms of their employment status. Factors related to accessed and mobilized social capital are also investigated. The subjects are 571 married women (284 employed and 287 unemployed) who have children younger than 5 years old. Their networks are revealed to show different composition and resource distribution according to the respective employment status. No significant difference is found in accessing social capital depending on the employment status. However, working women are capable of mobilizing more social capital for economic resources and child-care assistance than non-working women. The employment status is significant only in mobilizing social capital related to child-caring assistance. The effects of variables related to social networks of married women differ according to the types of resources sought for. The choices of married women on the employment status and child-rearing are observed in the findings of the ability to mobilize social capital for child-care assistance. The importance of kin ties and various social services for building social capital are discussed.
