Village Renewal(Dorferneuerung) Policy Program in Germany, directly originated from Rural Beutification Movement between mid 18C and mid 19C, has several characteristics as follows. First, we can find out the planned approach in land use and settlement reorganization of Pillage Renewal Program. There are three ways to designate the planning area of the village rearrangement project in countryside. One is to designate the detailed B-plan district by urban plan for the village over some size defined legally. Another is to have a living space of settlement be contained in land allotment project area. In this case, residential areas of several villages related to agricultural land consolidation should be simultaneously designated as the project area. The last is only for the built environment focused on the living space. Second, the emphasis in German village encouragement program can be made on the integral approach through which sets of policy programs of the land allotment, the living environment improvement, the physical landscape management and the cultural resources conservation are intensively implemented together. Third, the bottom-up and community participation approach can be greatly stressed on the planning and implementation process, Community participation, subsidy application to local government by residents themselves, community consensus on architectural style and outdoor spatial form, etc. have been recognized as an effective strategy to accomplish the task of village activity promotion.

This study focused on the architectural plan of the pension to meet modem people's desire for rural life, and the result of the study is as follows: First, the architectural plan for the characteristic of the location must apply the various architectural types considering the suburbs, tour and culture town, and community for the location improvement. Second, the architectural plan for the characteristic of the plot requires the encircled space and courtyard between buildings, the private gardens for the rooms, and the consideration of the surrounding environment. Above all, the plan for the subsidiary facilities is the most important. Third, the architectural plan for the characteristic of the plan requires the close connection with the outside, the wide opened view from the guest room, and the individual entrances for the guest rooms. Fourth, the architectural plan for the characteristic of the decorative design must consider the mass separation plan, the application of the facade design factors and eco-friendly environment materials, the night illumination plan, and the space program for the scenic view.

In the nowadays years our city's housing environment which progresses rapidly social-economical development is posited the role in the nowadays multi-family housing brings about the individualism of the nowadays city, and makes muddy neighborhood meaning, and the quality of the nowadays city dwelling house environment becoming worse. This study was started with the cognition of the need of intermediate-space, in the our life in the neighborhood city. Intermediate-spaces, has same meaning to come into the action of consciousness of the neighborhood. For the improvement of the quality of city housing, we should cleary recognized the individual territory after we set the proper in intermediate-zone in the multi-family housing. Therefore, this study inquires ito the meaning of intermediate-zone, and catches the formation technique of intermediate-zone and the method of plan through the investigation of the use cases of the multi-family housing which is established intermediate-territory. and then I analyze the role of the formative space by this method. By this method, I grope for the effect of the use through the alternative plan of the design method of the intermediate-zone. If the methods of play use the role in the nowadays multi-family housing, high quality will build up.

This paper proposes a sensor-fusion technique where the data sets for the previous moments are properly transformed and fused into the current data sets to enable accurate measurement, such as, distance to an obstacle and location of the service robot itself. In the conventional fusion schemes, the measurement is dependent on the current data sets. As the results, more of sensors are required to measure a certain physical parameter or to improve the accuracy of the measurement. However, in this approach, instead of adding more sensors to the system the temporal sequence of the data sets are stored and utilized for the measurement improvement. Theoretical basis is illustrated by examples and the effectiveness is proved through the simulations. finally, the new space and time sensor fusion (STSF) scheme is applied to the control of a mobile robot in an unstructured environment as well as structured environment.

항공기용, 함정용 레이더에 비해 비교적 정적인 지상 레이더의 운용 환경을 고려하면 정적인 환경에서 경사면을 측정하는 경사계 등에 사용되는 가속도계로 레이더의 정적인 자세각을 측정할 수 있지만, 바람 및 돌풍 또는 회전하는 안테나의 원심력 등에 의해 동적인 움직임이 발생하게 되는 경우 각가속도가 발생하여 자세각 측정에 오차가 발생할 수 있다. 본 논문에서는 위와 같이 발생한 자세각 측정 오차와 표적 위치에 따른 추적 오차에 대해 분석하고, 가속도계만을 사용한 동적 자세각 측정방법을 제시하고 이에 따라 개선된 추적오차를 시뮬레이션을 통해 결과를 나타내었다.

Purpose : Ministry of Health & Welfare started to 'Comprehensive care ward' project for patient hospitalization in order to help the economic and medical By providing comprehensive care services through professional nursing staff since 2013. Many physical environments changes are expected by providing comprehensive care services. The purpose of this study is to investigate the comprehensive care services and identify the problems of the corresponding physical environment usage. Methods : Data were collected through research, field surveys, and expert interviews to analyze and investigate the physical environment of the 'Comprehensive care ward'. Results : Physical environments changes in accordance with the comprehensive care services provided in 'Comprehensive care ward' are being only partially achieved. It have to considered not only ward environmental improvement for nursing services provided directly to the patient, but Including nurses warehousing space, work space. Implications : Comprehensive care ward project is scheduled to be operational even some wards throughout the hospital since 2018. This study is basic research for architectural planning of the future ward with comprehensive care services in public hospital.

Guided by a resource-based theory, this study is the first one that takes a quantitative approach to identify determinants of competitiveness of women-owned small and medium enterprises (SMEs) in Vietnam. The study employs time series data of Vietnamese SMEs extracted from the Vietnam Small and Medium Enterprises Survey conducted biennially from 2005 to 2015 in ten Vietnamese provinces. Firm competitiveness hereby is indicated by revenue, market share, profitability, and export volume. The research reveals a number of determining factors, of all, research and development, labor skills, business environment, technology investment are the most important factors, followed by capital and headcount. It is indicated that the determining factors have different influences on competitiveness obtained by different measurements. Therefore, it is based on specific targets and situations to make wise business decisions. The authors also make comparisons among groups of women-owned enterprises divided by their firm age, location, ownership, export, age, and educational background of business owners. The findings serve as critical empirical evidence and provide policy recommendations for improving the competitiveness of women-owned SMEs in Vietnam. The recommendations range from technology support, education and professional support for female entrepreneurs, access to capital and human resources to business environment improvement.

본 논문은 전투기 레이다 공대공, 공대지 동시 운용 모드에서의 빔 스케줄링 방법을 다룬다. 양질의 전장 상황 인식을 위해 임무들의 우선순위와 더불어 공대공, 공대지 탐색 임무가 교차로 수행되어야 한다는 요구조건을 정립하였다. 그리고 이를 만족하기 위해 WMDD를 개선한 실시간 휴리스틱 빔 스케줄링 방법을 제안한다. 제안된 스케줄링 방법은 실제 레이다 임무 처리 메커니즘 및 측정 모델이 구현된 시뮬레이션 환경에서 비교 분석하였으며 임무 지연시간 관점에서의 성능 향상을 확인하였다.

이동통신 환경에서 송신 다이버시티를 이용하는 STBC-OFDW(Space Time Block Code-Orthogonal Frequency Division Multiplexing) 시스템의 성능은 두 심볼을 전송하는 시간 동안 채널 특성이 변하지 않을 경우, MRRC (Maximal Ratio Receiver Combining)의 다이버시티 이득을 얻는다. 그러나 채널 특성이 변하게 되면 수신단에서 수신 심볼간에 서로 간섭영향을 주기 때문에 MRRC의 다이버시티 이득이 발생하지 않는다. 따라서 이동통신환경에서 송신 다이버시티를 적용한 이동체가 고속으로 이동할 경우 이러한 간섭영향에 의한 성능 감소의 영향을 줄일 수 있는 방안이 필요하다. 본 논문에서는 이동통신 환경에서 개선된 송신 다이버시티를 이용하여 STBC-OFDM 시스템의 성능을 개선시킬 수 있는 수신기 구조를 제안하였다. 제안하는 구조는 수신단에 ZF(Zero Forcing) 알고리즘을 이용한 간섭제거기를 사용하여 전송대역폭의 변화 없이 다이버시티 이득을 얻을 수 있다. 시뮬레이션 결과 도플러 주파수가 클수록 성능 개선 정도가 커지는 특징을 갖는다.
