본 논문에서는 자세 교정에 도움을 줄 수 있는 압력센서 기반의 스마트 방석 개발 사례를 소개한다. 스마트 방석은 스마트폰과 블루투스로 연결되며 스마트폰 앱은 사용자의 자세 정보를 분석한 후 자세가 불안정한 징후가 판단되면 알림을 통해 바람직한 자세를 취할 수 있도록 안내한다. 본 시제품 개발에서는 압력센서의 값을 분석한 후 단순한 형태의 자세 추정 방식을 채택하였지만 향후 다양한 실험 및 딥러닝 응용을 통해 정확한 자세 추정을 위한 알고리즘을 개발할 계획이며 알림에 의한 수동적 자세 교정이 아닌 기구 설계, 모터 제어 등을 통해 능동적인 자세 교정을 지원하는 스마트 방석을 개발할 계획이다.

While economic incentives have led to migration, the failure to adapt to a new city and to ease the financial burden to support families have raised migrants' intention to return to their hometowns. Using the 2016 China Migrants Dynamic Survey, this study investigates determinants of migrants' intention to return. Migration at a young age, which is associated with lower barriers to the new culture, and intraprovince migration requiring less effort to adapt to the new city, were associated with lower intention to return. Also, migrants with less burden to support a family tend to have a higher intention to return to rural hometowns. Specifically, migrants with children over 18 years old and fewer family members are likely to return to their hometowns. To revitalize rural economy and reduce the rural-urban disparity, a policy to support migrants with high intention to return will be needed.

Domestic industrial complexes have more loss competitiveness due to their deterioration length and environmental problems. Therefore, it is necessary to suggest the direction of realignment as advanced industrial estates and establish new alternative plans for improving the quality of public and environmental designs as well as reinforcing the competitive power. This study examined the design planning factors affecting the service users' satisfaction in the Seoul Digital Industrial Complex through a PLS regression model. The research result showed that 12 crucial design planning factors out of a total 31 planning factors have a more than 1.0 VIP. In addition, 8 comparatively important planning aspects that were measured between 0.9 and 1.0 were also investigated. These factors were the strategic design planning factors estimating the quantitative priority while enforcing the design improvement project and they should be considered as a useful material for strengthening the competitive power of the Seoul Digital Industrial Complex.

This study tried to derive the elements of the plan, recognizing the importance of taking into account the social weak when construct community facilities. For these, this study found planning indicator around literature review, then re-established indicators by Focus Group Interview. So it can draw following implication through result of analysis. First, planner considering the social weak should make fair space for harmonious communication between users. physical planning is important, but the building is to be vehicle for the social communication. So it needs to compose program without social elimination. Second, it is important to make participation base for the social weak in community facilities. Finally the reinforce of participation base can be indicator which encourage ownership and locality.

To define a small river in Korea. hydrologic- and geographic-characteristics. such as watershed area, channel slope, channel length and time of concentration are investigated and their limits are presented. The current equations of design-width-determination of the small rivers are examined and two equations for the design-width-determination of the small rivers have been suggested in this paper. A small river in Korea can be defined that watershed area is less than $10km^2$, channel length less than 6 km, channel slope over 0.02. time of concentration less than 30 minutes. As Band Q are defined as a design width and a design flood, respectively, the suggested equation to determine the design width is $B=1.235Q^{064}$ for less than $300m^3/sec$ of design flood. and when B and A are defined as a design width and a watershed area, respectively. the recommended equation is $B=8.794A^{0.56}$ for less than $10km^2$ of watershed area.

Land Use Information is the key of the rational decision in urban and regional planning. Although the local and central governments have data related to land use, urban and regional planners can gather the land use information in difficulty. For use the data which the governments have made, they should formally show their needs and applications, On this background, this study try to show the demands of such information for urban planning using questionnaire. Analyzing the result, it can present the hardness of gathering land use information, the high demands, and the needs of the each data field.

This study was performed in order to contributing the conflict factors which largely affects the efficient promotion of Urban Rehabilitation Project. then, it aims to induce conflict factors which affect the business period and business expense through PLS Regression Analysis. The data was build up from union members, tenants and merchants who are living in the completed urban rehabilitation area. In the case of 'Business period', it shows the priority on conflict factors in this order such as the 'Approval and Authorization for union establishment', 'Approval and Plan for business enforcement' and 'Interruption of interest group related to service business such as business delay'. In addition, In the case of 'Business expenses', it shows the priority on conflict factors in this order such as the 'Approval and Authorization for union establishment', 'Selling contract', 'Report of Demolition and Loss' and 'Plan and Authorization of Management disposition'.

The purpose of this study is to understand immigrant women's knowledge of menstruation, attitude towards menstruation and knowledge of contraception. The study employed a descriptive survey. The participants were 120 married immigrant women in Chonnam area. Data were collected through questionnaire and interview from July to December, 2009. The participants had average score in knowledge and attitude of menstruation and knowledge for contraception. There were statistically significant differences in knowledge of menstruation according to nationality, level of satisfaction with current lifestyle, perceived health status, number of children desired, and sources of contraceptive information. There were statistically significant differences in attitude towards menstruation according to age, nationality, perceived health status, and number of children desired. There were statistically significant differences in knowledge of contraception according to level of education, nationality, and dysmenorrhea. According as the attitude toward menstruation increased, the knowledge for contraception decreased. The results of this study suggest a need for multidimensional strategy to raise knowledge of menstruation and contraception for married immigrant women.

The statistical analyzing of environmental-friendly planning elements is getting important because it is getting concerned with the change of residential types and environmental friendly housing. However, in terms of the high-rise residential complex, paper about green building rating system and research about residential satisfaction to residents are lack. Therefore, this paper is analyzing of impotentness and satisfaction about housing subdivision, inside of building, facility, and maintenance. In addition, residential satisfaction(satisfaction, loyalty, preference) and impact relationship of environmental-friendly planning elements are analyzed by PLS structural equation. To sum up, first, improving of green building rating system in housing subdivision is impacted on loyalty if satisfaction was fulfilled. Second, increasing of environmental-friendly planning elements in inside of building is impacted on loyalty if both satisfaction and preference were fulfilled. Third, providing of green building rating system in facility and maintenance is analyzed as preference, but satisfaction hypotheses is not valued.

The $LCCO_2$ evaluation programs previously developed in Korea involve limitations in establishing strategies of reducing environmental loads to optimal level in a way to put in materials directly after designing. Therefore, this study has the purpose to extract and propose elements required for the establishment of highly accurate system by counteracting swiftly in a method with high energy efficiency over cost at planning stage. To that end, existing $LCCO_2$ evaluation programs in Korea and abroad were compared and analyzed, and in the planning stage, GEM-21P and Carbon-navigator intended for the establishment of building energy performance improving strategy were selected as the evaluation program for survey. On such basis, after comparison and analysis between $LCCO_2$ calculating methods and system structures of the two programs, elements required for system establishment that can evaluate life-cycle environmental loads of building in planning stage were proposed.
