The purpose of this study is to analyze the effects of local community resident-participation factor on the local community resident-participation determinant and the formation of social capital. Accordingly, questionnaire method was used for 389 residents in A-dong that have participated in community building projects in Busan region to analyze their demographical factor & residential area factor and local community resident-participation factors of satisfaction of neighborhood environment, satisfaction of administrative support, local attachment and neighbor connectedness effects. The analysis results showed that first, the satisfaction of outside support and neighbor connectedness were found to be the main factors. Second, the satisfaction of outside support, local attachment and neighbor connectedness showed meaningful effects in the state where these factors were controlled. Third, the effects of each social capital sub-element were verified and the results showed that while trust and network had meaningful effects on satisfaction of outside support, local attachment and neighbor connectedness effects, norm of reciprocity showed meaningful effects on gender, house ownership status, local attachment and neighbor connectedness, thereby showing differences. Based on these study findings, implications and suggestions were presented.

This study examined the nature of multi-cultural families' housing problems living in South Korea. A qualitative research was conducted through in-depth interviews with immigrant women from three Southeast Asian countries. The subjects of this study were 15 married immigrants from the Philippine, Cambodia, and Vietnam living in Seoul. The major findings were as follows: firstly, reciprocity for the in-between person and environment: the preferred to blend into Korean society instead of making a community based on national origin. Secondly, intention to housing: all participants were passive about moving and the Vietnamese and Cambodians placed more importance on the family community than the Filipinas. Thirdly, meaning of housing and interaction: for the most important area in the house, the Vietnamese and Cambodians stated that rooms were for a couple and treated family space more importantly than Filipinas who pursuit personal comfort. Fourthly, housing adaptation process: adapting to climate difference between home countries and Korea was the biggest difficulty. Fifthly, residential satisfaction/dissatisfaction: mostly satisfied with housing facilities; however, they were dissatisfied with the number of rooms and house size due to a necessity for personal space. In conclusion, ideas implied from native country of married immigrants in multicultural families did not change significantly in preference of the current environment. The needs for an ethnic community was not great, because they seemed able to assimilate positively by living with a Korean husband and relatives. Gradual assimilation through a cultural acculturation process can be considered desirable.

The present study aims to evaluate the potential accessibility of public healthcare facilities in rural areas. Population is prepared and analyzed in spatially microscopic level using dasymetric mapping method. According to the analysis on the accessibility to public facilities which is conducted using shortest distance, Gun areas and Eup/Myeon areas are 1,845m and 1,777m from residential areas respectively. Areas in Gangwon-do and Gyeongsangbuk-do have relatively low accessibility while Eup areas tend to have higher accessibility. The present study is meaningful in that it shows the status quo of and regional differences of potential accessibility of rural public facilities in Korea. Furthermore, the findings are also meaningful as they can be utilized as fundamental data to locate the facilities and improve the service delivery of medical facilities.

Purpose: Many design index that are using in planning phase have been developed. The most popular things among them are Window to Wall Ratio and Surface to Volume Ratio. However there are some limits. Window to Wall Ratio cannot consider building size and Surface to Volume Ratio cannot do Window to Wall Ratio. Accordingly, in this paper, the Window to Floor Ratio was proposed that it can be considered both building size and Window to Wall Ratio. And analyzed correlation of energy demand. Method: For the test, 16 modules with the size of $6m{\times}6m{\times}4m$ were used to make 35 models with the same volume. The simulation was conducted to 945 cases using the window-to-wall ratio of 30, 50 and 70 % in three areas such as Seoul, Gwangju and Jeju and three kinds of windows. And IES_VE was used. Result: The findings above show that the Window to Floor Ratio that can be considered both building size and Window area have to become as design index. It was found out that design criteria with SHGC is necessary, not with the thermal performance (U-value). It is needed to additional analysis about residential building and the effect of 24-hours heating and cooling condition. It plans to carry out research to establish design indicators for climatic conditions in the country and building applications.

As Power Line has been already installed over 60% of a residential area all over the world, Broadband Service has been possible using high-speed PLC(Power Line Communication) without new access line installed for Internet access. Because of such reason, PLC is researched as the most suitable service for Last Mile Solution. But, Power Line is designed for transmitting electric power, so peripheral Wireless Communication System is affected by a leak of electric wave. In this paper, we propose a High Performance Notch Filter algorithm in comparison with a existing notch filter for reduction of interference between existing Wireless Communication Service and Power Line Service. In addition, we implement the Notch Filter emulator appling a High Performance Notch Filter and using a embedded board.

Objectives: This study aimed to examined the socioeconomic disparities in oral health related behaviors and to assess if those behaviors eliminate socioeconomic disparities in oral health in a nationally representative sample of adults aged 30-64. Methods: Data are from the Korea Third National Health and Nutrition Examination Survey (2005). Behaviors were indicated by smoking, over intake of daily calories from carbohydrate, perceived stress, frequency of daily tooth brushing, use of oral hygiene goods, insufficient oral treatment. Oral health outcomes were self-reported dental caries and periodontitis during the last 12 months and perceived oral health. Education, household income, and employed status indicated socioeconomic position. Sex, age, residential area, marital status were adjusted for in the logistic regression analysis. Logistic regression analysis was used to assess socioeconomic disparities in behaviors. Logistic regression model adjusting and not adjusting for behaviors were compared to assess the change in socioeconomic disparities in oral health. Results: Clear socioeconomic disparities in all behaviors were showed. After adjusting for behaviors, the association between oral health and socioeconomic indicators attenuated but did not disappear. For example, the odd ratios of reporting poorer oral health for persons in no education or elementary school education and middle school education groups, compared with college or higher education group, were 1.77 (95% CI: 1.36-2.29) and 1.56 (1.19-1.97), respectively. After adjusting for all indicators of behaviors, these odds ratios attenuated to 1.54 (1.17-2.03) and 1.48 (1.15-1.91) for those groups, respectively. Conclusion: These findings suggest that the presence of more complex determinants of socioeconomic disparities in oral health should be considered with developing preventive policies for those disparities.

The purpose of this study was to examine factors contributing to financial resources interchange type and amount of the middle aged and the elderly household. For this study, the 6th KLIPS data was used, and sample size was 1,679 households including those with head of household being over the age of 50. Statistical analysis was conducted to examine frequency, percentile, mean and standard deviation, Pearson's correlation, Anova, Duncan's multiple range test and Heckman analysis First, Interchange amount of Benefits type household was significantly different according to the householder's gender, existence or nonexistence of a spouse, age, educational background, home ownership, family type and place of residence. However, interchange amount of provide- type households were significantly different according tohouseholder's gender, existence or nonexistence of a spouse, educational background, whether retired or not, and home ownership. Second, The receptive type of households and net receptive expense of households in terms of the financial resources interchanges and the findings of Heckman analyses suggest that the variables to have a significant effect on the receptive types of financial interchanges were as gender, age, education level, retired or not, and current economics. Factors having an effects on net receptive expense were age, and family type and for the number of receptive of financial resources, whether there is the receptive of financial resources, total income, total asset. Third, The supplying type of households and net supplying expense of households in terms of the financial resources interchanges, whether or not the type of financially supplying households is significant were residential area, total income, house ownership. Factor having an effect net supplying expense were age, family type, whether there is the supplying of financial resources, family satisfaction, and house ownership.

Surface evapotranspiration is one of the most important factors to determine the surface energy budget, and its estimation is strongly related with the accuracy of weather forecasting. Surface evapotranspiration over Daegu Metropolitan was estimated using high resolution LANDSAT TM data. The estimation of surface evapotranspiration is based on the relationship between surface radiative temperature and vegetation index provided by a TM sensor. The distribution of NDVI (Normalized Difference of Vegetation Index) corresponds well with that of land-used in Deagu Metropolitan. The temperature of several part of downtown in Deagu metropolitan is lower in comparison with the averaged radiative temperature. This is caused by the high evapotranspiration from dense vegetation like DooRyu Park in Deagu Metropolitan. But, weak evapotranspiration availability is distinguished over the central part of downtown and the difference of evapotranspiration availability on industrial complexes and residential area is also clear.

Recently, most of residential-commercial buildings and apartment houses which are being constructed in the downtown area mainly adopt hybrid structural systems to compose various spaces. Especially, column-supported wall system which is one of the hybrid systems includes shear wall and rigid frame structure and these structures are connected by the transfer floor. But this system is very disadvantageous from the viewpoint of structural safety and is difficult to find out the stress distribution at the transfer floor. Therefore, this study analyzes the behavior and stress distribution according to the shear wall layout of transfer girder system subject to vertical and static lateral loads. Also, this study recognizes load paths and stress concentration based on the analysis results nearby the transfer floor and presents guidelines for the effective design of wall and transfer girder.

Solid waste collection service is viewed as one of the most important public services in urban area. The purpose of this study is to apply the GIS based regional partitioning and arc routing methods for solid waste collection districting and vehicle routing-scheduling in order to provide waste collection service more efficiently. In this study, solid waste deposit sites are derived from the centroid of each building and the amount of solid waste is deduced based on the number of households and establishments. The regional partitioning procedure is performed based on waste collection zones which are constructed from waste deposit sites. The result of this study shows that solid waste collection districts which are delineated by regional partitioning method are able to increase efficiencies and cut costs in performing solid waste collection services. Also the output of vehicle-scheduling from the analysis of arc routing may provide more efficiently and quickly manage the scheduling of the residential solid waste collection routes, reducing costs with minimal deadheading costs. Therefore, the application of GIS based on regional partitioning and arc routing methods would be very useful to construct a solid waste management system by supplying the important and flexible informations for solid waste collection districts and vehicle routing-scheduling for waste collection.
