정지궤도급 차세대 통신위성에 탑재될 디지털신호처리기에는 디지털 고속통신을 위한 FPGA가 사용된다. 적용된 FPGA는 높은 열소산량을 가지고 있으며, 이로 인한 접합온도의 상승은 부하경감 요구조건을 만족하기 어렵고 장비의 수명과 신뢰도 저하의 주요 원인이다. 지상과는 달리 우주환경에서의 전장품의 열제어는 대부분 열전도를 통하여 이루어지고 있다. CCGA 또는 BGA 형태의 FPGA는 인쇄회로기판에 장착되지만, 인쇄회로기판의 열전도율은 FPGA의 열제어에 효율적이지 못하다. FPGA의 열제어를 위하여 부품 리드와 하우징을 직접 연결하는 히트싱크를 제작하였으며, 우주인증레벨의 열진공시험을 통하여 그 성능을 확인하였다. 높은 전력소모량을 가진 FPGA는 우주환경에 적용하기 어려웠으나, 히트싱크를 적용함으로써 부하경감 온도 마진을 확보하였다.

The purpose of this study was to provide basic data for development of a recipe for muslim-friendly halal Korean foods through investigation of awareness of Korean foods, taste evaluation, and menu preferences. After Korean foods' menu range and standard were set up for the survey and in-depth interviews with three halal food experts were conducted, 35 kinds of halal Korean foods were examined. The present study conducted a survey on 205 foreign Muslims living in Jeonju-si, Jeonbuk and Gimpo-si, Gyeonggi who ate Korean foods. Foreign Muslims were male workers in their 20's residing in company housing, and their monthly mean income was 1.01~2 million KRW. The majority of subjects responded that meal problems were the most difficult in everyday life. Concerning the taste of Korean foods, the response rate of 'sweet' and 'spicy' was high while 'Korean food is healthy' and 'Korean food ingredients is fresh' were high for awareness of Korean foods. 'Bulgogi' was the most preferred among the selected Korean foods, which was in line with the results of previous research. There is a need to provide information on Korean foods that can be made with food ingredients certified as halal and their recipes through various media for foreign Muslims who have limitations on in meals due to religious factors.

The purpose of this study was to gain a better understanding of households with a negative cash flow. The Household Budget Survey conducted in 2000, 2005, and 2010 by the Bureau of Statistics in South Korea were used for this study. The households used in this study were divided into four groups according to their income levels; they were categorized the lowest, low, middle, and high income groups. This study made several findings regarding households with a negative/positive cash flow. Firstly, the demographic and economic characteristics were different between those who have a negative cash flow and those with a positive cash flow. A female household head, a household head age 65 and older, a household head with a lower educational attainment, an unemployed household head, and the presence of a child/children in schools were related with the household deficit. Secondly, the households with a positive cash flow had a higher income level compared to the households with a negative cash flow, while the households with a negative cash flow had a much higher consumption level compared to the households with a positive cash flow. Thirdly, the household deficit to total income ratio of the lowest income group was higher when compared to any other income group. Lastly, the multivariate statistics showed that households including a child/children in schools are more likely to be a household with a negative cash flow. Especially, the expenditures on education and transportation were related with the likelihood of a household deficit.

The goal of this study is mainly to improve the quality of life for the elderly by understanding the actual condition of the home management which includes their family relationship, family finance, and household work carried out in their domestic lives and diagnosing problems possibly restated from the condition. The result includes the following. The characteristics of rural elderly living alone: They have lived in rural area since their marriage which is over 40 years long in average, The tend to be satisfied with living apart themselves. The majority of the families are the first son in their family. In home management regard: First, in family relationship, the way the elderly in their nuclear family state communicate with their spouse is limited, and they hardly speaks together. So it is encouraged for couples to forge their own specific relationship and to plan for their odd age in their younger age. Also, they tend to be satisfied with living separated from their children, but at the same time, the closer they live in distance from their children, the more often they meet their children as well as they talk on the phone. They especially depend on their first son for offerings for ancestors and matters to occur after their death, while they get emotional support from daughters. Second, in family finance, their income varies in range from 200,000 to 3,000,000 won. In the majority f the famines, the wives are in charge of finance. The cost of living is mainly spent on flood, clothing, and housing, or the cost of offerings for ancestors if they are the head family.

A new movement in forming community villages for better living standards is becoming popular. In order to sustain a proper community, it is essential to design proper community programs and facilities, which can encourage the proactive participation of residents. In this study, detailed aspects of the Mindlre (Dandelion) community (including formation process and management of the village) are investigated. The Mindlre community is a successful community village in Korea concerned with residents' participation and community activities. The community is located in Sancheong, Gyungsangnamdo province in Korea. The study methods are references, field trips, and interviews with residents. Six areas were surveyed and investigated: the physical environment of the Mindlre community and eco-friendly elements, respondents' background and the motivation to join, residents composition, residents' participation in the formation process of the community, self-management systems and common activities, and residents's life satisfaction. The mindlre Community was founded on Christian religions faith. The primary idea of this village was building a new hope for rural areas without discrimination. The size of the village was expanded with housing for teachers and students who were linked with the Mindlre School (substitution school). When the community was founded, existing shapes of the village were preserved. The village was physically renovated based on the original environment, in addition nature friendly materials and methods were used. The residents were proactively involved in the community through regular meetings, self-regulation, and community worship. Although the survey results should that most residents were highly satisfied with living standards, there seemed to be no clear division between community facilities and private houses. A systematic and detailed space planning technique was required. In addition, various community facilities are required due to the expansion of the community.

We developed an education program for parents of adolescents titled Parents from Mars getting through to children from Venus. The program consists of five two-hour sessions each with a different theme; (1) parent-child communication, (2) study activities, (3) computer use, (4) children's daily expenses, and (5) children's daily-life plan. The program was test-run with seventeen participants, which included mothers of 4th grade(elementary school) to 9th grade (middle school) children. Based on data analysis, we found that average satisfaction level was 3.80 out of 5.00 and average goal accomplishment level was 3.91 out of 5.00. Most of the participants agreed that the program helped them to understand their children's problems, to look back on themselves as parents, to plan ahead, and eventually to improve their relationship with their children. However, it was also pointed out that the program needed to put more emphasis on practical lessons rather than theoretical lectures. For example, the need for more audiovisual materials, and more practical training during each session was highlighted by participants.

The purposes of this study were to examine low-income households' financial statuses and the socio-economic characteristics of single-person and non-single person households according to the financial indexes used for evaluating financial security and growth status developed based on financial ratios. Using 2009 KLIPS(Korean Labor & Income Panel Survey) data collected by the Korean Labor Institute, the satisfaction levels from the indexes were analyzed and compared between the two household types. The results showed that 46.0% of single-person households were not satisfactory in terms of all financial growth indexes but were partially satisfactory in terms of all financial security indexes. These householders tended to be females and in the their 70s, who lived in Seoul or in a suburb of Seoul, Korea. They reported problems with a lack of financial growth possibilities. 47.0% of non-single person households were not satisfactory in terms of all financial growth indexes but were partially satisfactory in terms of all financial security indexes. These householders tended to be males in their 60s and 70s with no job who were living in Seoul or in a suburb of Seoul, Korea. They reported having low level of liquidity and high level of debt redemption. 42.6% of single-person households were not satisfactory in terms of both financial security and growth indexes partially. These householders tended to be females in their 20s or 70s who were living in rural areas. They reported problems related to an adverse balance between household income and expenditures and a large scale of debt. 43.1% of non-single households were not satisfactory in terms of both financial security and growth indexes partially. These householders tended to be males in their 60s or 70s and homeowners. They reported problem related to an adverse balance of household income and expenditures and high a level of housing expenditures and liquidity. The research findings have implication for policy makers considering financial support programs and welfare programs for low-income householders, considering the recent changes in households structures.

The purpose of this study is to establish the identity of the traditional residential space in Korea and Japan as analyzing the spatial characteristics and sociocultural roles of the 'in-between space' shown in their traditional dwelling space. Although they share culture area, it is meaningful to clarify the identity of both countries with many differences as the point of localization In globalization and the point of presenting the current and future directions of residential culture in both countries. Records and field studies have been carried out for the spatial characteristics and the sociocultural role focused on Ma-dang and Dae-chung in case of the 'in-between space' in Korean traditional dwellings and Inner housing, Doma, and Engawa in Japan. According to these findings, the spatial characteristics in common between Korea and Japan are open, half-open, separation, mitigation, integration, variation, continuation, hierarchy, mediation, and expansion. The 'in-between space', built by the separate Chae and Kan, of Korean traditional dwellings shows the separation by closed walls and the exclusive use by the fixed walls. In case of Japan, the integrated in-between space built by the separation of Kan shows open and connective tendencies and the variableness of walls has the tendency making ambiguous space with spatial softness. The sociocultural role of the 'in-between space' in Korean traditional dwelling space functions as the mitigation between the interior and exterior of the house as well as the male and female. Because the conception for protecting the private life is too weak, the sociocultural role of the 'in-between space' in Japanese traditional dwelling space seldom forms the space for an individual or the specific person among family. The space to welcome a guest functions as the mitigation between residents and outsiders as it is located in the inside of the private dwelling space.
