  • Surface sediment samples from 31 stations in Jinhae Bay were analyzed to evaluate the pollution by sewage from the spatial distribution of the fecal sterol, coprostanol. The sums of eight sterols (coprostanol, epicholestanol, epicoprostanol, cholesterol, cholestanol, brassicasterol, stigmasterol and $\beta$-sitosterol) were in the range of $2,703-27,154{\cal}ng/{\cal}g$ dry weight. The concentrations of the coprostanol in the sediments, which is a good tracer of sewage-derived organic contamination, were in the range of $76-3,964{\cal}ng/{\cal}g$ dry weight. The levels of coprostanol were much higher (almost one order of magnitude) at stations close to the big cities such as Masan and Jinhae. However, those levels were comparable to or lower than those previously reported in other foreign locations. Some ratios of coprostanol to other sterols and multivariate analysis could provide us with the information on the origin of the sterols being from sewage, plankton, and/or benthos. Those showed sewage dominance at the stations near the cities Masan and Jinhae, plankton dominance at the center of Jinhae Bay and mainly marine fauna origin at the mouth of Jinhae Bay. These results suggest that the contents of sterols and some ratios of these components are quite powerful tracer for the detection of the origin of the organic contaminants in the coastal environments.

  • Comparative studies on the quality of life, a new research specialization,have emerged only in recent years and are experiencing vigorous development in many parts of the world This study is a two year phasing-in project carried out by a jointed research team between Seoul National University and Tokyo University. As the first study of the project series, the aim of the study is to learn how different the quality of life(QOL) between Seoul and Tokyo and how the students of both cities assign the relative weights to parameters of the quality of life in their cities. The study also attempts to illustrate the current state of the art in this new field. Seoul and Tokyo are located very closely bur their physical, socia-economic and cultural aspects are not the same but rather different. Here is our interest and the reason why we started out study. The study is divided into the following two principal parts: (1 ) The survey of the variables influencing the puality of life in Seoul and Tokyo (2) The survey of the attitude of students towards the relative importance of parameter of the quality of life in Seoul and Tokyo. The researches of the variables were carried out utilizing the existing official statistics derived from 1988 Seout Statistical Year Book and 1987 Tokyo Statistical Year Book. Therefore, the choice of indicators was largely limited to data that had been compiled in two yearbooks. The attitude surveys of students were carried out by interview. The questionnaire consists of a face sheet and a question which is designed to produce information on the relative importance of the parameters by the paired comparison method.

  • This study intends to analyze urban peoples' leisure choice attributes of rural areas from a rural demand perspective. For this purpose, this study investigates regional attributes considered in decision making processes for rural tourism destinations of urban residents using a conjoint model as a stated preference model. Based on literature reviews, two questionnaire surveys were conducted. The first questionnaire survey was performed in 4 cities including Seoul, Daejeon, Suwon and Chuncheon with 408 urban residents. The Second questionnaire survey was performed in 5 cities including Seoul, Chuncheon, Daejeon, Jeonju and Busan with about 1,060 urban residents. The study results suggest that the most important attribute in selecting rural ares for tourism are activity programs and convenience of facility, according to part-worth and vector model. The fitness level of model is 0.986, which is very significant. Among the 5 attribute's levels, the rural residents' kindness, the traditional and the ecological programs and the facilities about sign and lodging are more critical factors than other levels. Utilities of each levels decreases as cost and arrival time increases. Regarding the result of market segmentations, respondents having intention to visit can be divided into 4 group; (1) facility or program oriented type, (2) resident's kindness oriented type, (3) arrival time oriented type, and (4) negatively participant type. The results of leisure choice attributes can provide insightful information for regional planning strategies, such as selection of the type of market segments and the key factor of facility and space planning.

  • In rural areas, in spite of the development projects of town and houses has been performed after the New Community Movement, due to rapid industrialization and urbanization, which lasted until the 2000s from the 1980s, out-migration to the cities, changes in the industrial structure, rapid aging was carried. As a result, the gap of housing environment between urban and rural areas became more serious. The meantime, the housing problem is recognized only to the problems of the big cities, mostly urban public housing policy oriented. However, when you check the indicator of the housing environment, such as the percentage of aging housing, rural environment has become a relatively poor compared to the city. In addition, due to a decrease in income and aging of the population living in rural areas of existing infrastructure to improve the living environment is weakened. And inside of the rural areas, changes in the housing environment and polarization phenomenon is becoming increasingly serious. Therefore, in this study, there is a purpose to be presented the improvement direction for efficient implementation of house remodeling support program for underprivileged group in rural areas and requires immediate attention improvement of housing environment. Previously, House remodeling support project in rural areas was carried out at the initiative of local governments and government mainly. For this reason, it is difficult due to limited institutional, to reflect the necessary parts directly to the real life of the residents. And, the demand for improvement of housing environment need modifications to solve the inconvenience of life of residents directly in many cases. It is considered that community-based house remodeling support project is to be carried out through the participation of local residents.

  • Nowadays, global wedding dress companies are interested in the Chinese wedding market because of expectations in consumption patterns of the post 80's generation. Therefore, wedding behavior, selection criteria for wedding dresses, and favored image by segmented groups targeting 20's to 30's Chinese women were studied to help the Korean wedding dress industry to establish their business in China. The survey was conducted in Shanghai city and three neighboring cities-Wuxi, Zhengziang, and Hangzhou-, and the primary data were analyzed using the SPSS program. As results, Chinese women thought that the wedding ceremony should be elegant and dignified, and they wanted to choose their favorite style rather than a recommended style. The criteria of selection were classified into four factors. Overall image and well fitting with their face and body were the most important factors in the selection of wedding dress. The most favored image was unique/novel image. Several favored images for their wedding dress were significantly different by occasion (ceremony day and photo shoot day) and education level. People of higher education level preferred more luxurious and classic image during the ceremony, and a classic and gorgeous image on the photo shoot day. A white dress and a colored dress for weddings were favored more than the Chinese traditional dress on both occasions. There was also a significant difference between general consumers and the wedding business employees in the quantity of wanted wedding dress.

  • This study aims to analyze the design of public libraries which act as anchors in culture-led urban regeneration. They have been built as city's symbols as well as catalysts to revitalize city centers and urban spaces since the 1990s. This study finds that the public libraries play roles in the urban development as cultural icons, multi-functional spaces, and public domain. This study examines the five examples of the libraries and finds their important design qualities as follow. First, public libraries are planned to symbolize local culture and history as cultural icons. The shapes of public libraries are expressed with sculptured cultural icons, while their facades are designed to signify cities' identities and images. Second, public libraries in culture-led urban regeneration have multi-functional spaces which provide diverse activities and experiences to visitors. The libraries often have galleries and theaters for cultural life, cafes and shops for daily uses, educational facilities, as well as public services, parking, and transport systems that connect to urban infrastructure. Third, the public libraries become the anchors of surrounding public spaces and cultural buildings. The libraries have the sequences of approach from entry plazas, transitional zones, and entrances to lobbies. Especially the transitional zones between the libraries and the cities that are covered with giant cantilevers expand the libraries' space and establish attractive urban spaces. Forth, the libraries employ nature and cityscapes in their design. The surfaces and openings of the libraries are adjusted to allow many attractive views to visitors. Fifth, the libraries have big lobby spaces which are the centers of the buildings as well as the public domain. The lobby spaces are designed as in-door spaces like out-doors with vertical and horizontal openness that allow the natural flows of light from ceilings, glass walls and vertical voids.

  • Background: The purpose of this study was to investigate longitudinal changes of the utilization of operational and surgical medical care inside and outside a metropolitan area over 10 years, analyzing the residential areas of patients and the locations of medical facilities for major cardiovascular surgery. Methods: Data analysis was conducted by classifying the addresses of patients and the locations of medical care facilities of metropolitan cities and provinces, using data from the National Health Insurance Corporation from January 2003 to December 2013. Results: There is serious concentration of major heart surgery to medical facilities in Seoul; this problem has not improved over time. There were differences in percentages of surgical procedures performed in the metropolitan areas according to major diseases. In the case of Busan and Daegu provinces, at least 50% of the patients underwent surgery in medical facilities in the city, but there are other regions where the percentage is less than 50%. In the case of provinces, the percentage of surgical procedures performed in medical facilities in Seoul or nearby metropolitan cities is very high. Conclusion: Policies to strengthen the regional capabilities of heart surgery and to secure human resources are required to mitigate the concentration of patients in the capital area. Many regional multi-centers must be designated to minimize unnecessary competition among regional university hospitals and activate a win-win partnership model for medical services.

  • Background: This study uses the relevance index to understand the condition of regional medical service use for cardiovascular surgery and to identify the medical service use imbalance between regions. Methods: This study calculated the relevance index of 16 metropolitan cities and provinces using resident registration address data from the Ministry of Government Administration and Home Affairs and the 2010-2014 health insurance, medical care assistance, and medical benefits claims data from the Health Insurance Review and Assessment Service. We identified developments over the 5-year time period and analyzed the level of regional imbalance regarding cardiovascular surgery through the relative comparison of relevance indexes between cardiovascular and other types of surgery. Results: The relevance index was high in large cities such as Seoul, Daegu, and Gwangju, but low in regions that were geographically far from the capital area, such as the Gangwon and Jeju areas. Relevance indexes also fell as the years passed. Cardiovascular surgery has a relatively low relevance index compared to key types of surgery of other fields, such as neurosurgery and colorectal surgery. Conclusion: This study identified medical service use imbalance between regions for cardiovascular surgery. Results of this study demonstrate the need for political intervention to enhance the accessibility of necessary special treatment, such as cardiovascular surgery.

  • Using data obtained from 1, 473 adults aged 18-68 yrs, residing in large cities and by use of a semi-quantitative food frequency questionnaire, we assessed the relative importance of various foods as indicators of both the amount and the variability of selected nutrient intake to develop a simple food frequency questionnaire. Since Cronba- ch's alpha value of the questionnaire including 78 food items was 0.76, the reliability of this questionnaire was acceptable. A large fraction of the variability of nutrient intake in this population could be explained by the small number of food items. The estimation of dietary nutrient intake such as total calories or protein content, which are derived from almost all foods, will require more food items with nutrients such as calcium or vitamin A, which are concentrated in a few food items. A dietary history ascertaining the intake of as few as 5-19 food items mighted be all needed in order to determent the associa- tion between disease outcome and the intake of a single nutrient. There was certainly a high level of agreement with nutrient intake by the sbujects who were cross-classified by quartiles of nutrient indices based on all the food items(78) and by quartiles of nutrient indices based on food items selected by stepwise multiple regression for selected nutrients. The data provided further evidence that useful information on dietary intake over an extended period can be obtained by a simple and relatively inexpensive food frequency questionnaire.

  • This study investigated the rates and reasons for breakfast skipping according to gender, age, and lifestyle related factors in Korean adults. The survey was conducted using questionnaires and the subjects included 1148 male and female adults aged 19-64. The rate of breakfast skipping (frequency of eating breakfast under 4 times/week) was 41.20% of the total subjects. The breakfast skipping rate of the male subjects was significantly higher than that of the female subjects (p < 0.001). As age and household income decreased, the breakfast skipping rate increased. Residents in small cities more frequently skipped breakfast than those in larger cities. The main reason for breakfast skipping was "lack of time for the preparation and consumption of food" and this reason was especially higher for office workers and younger adults among the participants. In addition, the proportion of habitual breakfast skippers increased with age. Among the answers regarding the person who prepares breakfast in their households, the highest proportion was for "family members" in the males and "myself" for the females. Of breakfast skippers, 77.63% answered that they consumed breakfast substitutes such as breads, dairy and fruits/vegetables. To summarize the results, the gender, age and lifestyle factors of adults were significantly related to the rates and reasons for breakfast skipping. Therefore, to reduce breakfast skipping in Korean adults, a differentiated nutritional education approach relative to gender, age, and lifestyle is needed along with the development of balanced breakfast substitutes.
