본 논문은 미국 포용주택 제도를 중심으로 사회적 혼합 달성가능성을 탐색하는 것을 주 목적으로 한다. 계획고권을 활용한 포용주택 제도의 발생 배경과 운영방식, 사회적 혼합 달성의 효과 및 한계를 검토하여 우리나라 주거정책에 대한 시사점을 도출하였다. 분석 결과, 시장중심적 정책이 우세한 국가임에도, 주택가격이 높고 부담가능주택이 부족한 대도시 중심으로 포용주택 제도가 활성화되고 있으며 용적률 보너스를 포함한 다양한 인센티브를 제공하며 민간의 참여를 유도하고 있었다. 또한 정책대상이 되는 중저소득층이 부담가능하도록 주택을 공급하며 최대한 장기간 저렴하게 유지되도록 의무화하고 있다. 이를 통해 확정적이지는 않지만, 사회적 혼합에 긍정적인 효과가 발견되고 특히 아이들의 교육 성취도가 높은 편이나, 유의미한 사회적 상호작용에 대해서는 여전히 그 성과가 실험중이다. 포용주택을 직접 해당부지에 건설하는 경우와 인근에 건설하는 경우로 나누어 사례분석한 결과 장단점이 모두 존재하는 것이 확인되었다. 이는 주택가격이 높고 빠르게 상승하는 대도시지역에서 중저소득층을 위한 부담가능한 주택공급 가능성의 단초를 제공한다.

최근 해양 수중 산업의 발전으로 수중 센서 네트워크(UWASN: Underwater Acoustic Sensor Network)에 대한 관심이 증대되고 있다. 수중 센서 네트워크를 효율적으로 운용하기 위해서는 노드 간 전송 충돌을 방지하고 통신 자원을 효율적으로 공유할 수 있는 매체 접속 제어(MAC: Medium Access Control) 프로토콜을 적용하는 것이 매우 중요하다. 하지만 수중 채널은 지상 무선 통신 환경과 달리 좁은 대역폭, 긴 전파 지연 시간, 낮은 전송률 등의 특성을 가지므로 지상 환경에서 개발된 비직교 다중 접속(NOMA: Non Orthogonal Multiple Access)의 노드 페어링 기법을 그대로 적용할 수 없다. 따라서 본 논문에서는 수중 채널의 특수성을 고려한 수중 음향 센서 네트워크에서의 비직교 다중 접속 다차원 노드 페어링 기법을 제안한다. 기존의 기법들은 노드 페어링 시 채널 품질만을 고려하였다. 기존 기법과 달리 제안 기법에서는 채널 품질 뿐 아니라 노드 간 공평성, 트래픽 부하, 패킷의 나이를 추가로 고려하여 최적의 노드 쌍(node-pair)을 찾는다. 추가적으로, 송신 노드는 실제 경로 손실 대신 노드 쌍 가능 노드 목록(PNL: Pairable Nodes List)을 활용함으로써 노드 페어링 시의 계산 복잡도를 줄인다. 시뮬레이션 결과에 따르면 공평성 요소까지 고려한 제안 기법이 기존 기법 대비 최대 23.8% 전송률 증가, 28% 지연 시간 감소, 공평성은 최대 5.7% 향상됨을 확인할 수 있었다.

The Fashion Distribution Business (FDB) is thriving to such an extent that the current period is called "The Era of Fashion." This FDB shows tendencies towards specialzation, globalization and expansion. The domestic FDB has been rapidly globalizing, and thus it is time for us to recognize that the fashion business has grown beyond its former role as a production-oriented retail business to include multiple new roles. This strategy to plant Store Identity on customers is just a Visual Merchandising (VMD) Strategy. That is, a strategy to visualize the Product Planning, which can be called a Complex Visual Expressing Technical System that classifies and arranges products in order to be easily seen, chosen, and bought through exhibition and arrangement. My aim is to break away from the conept that has been focused only on display division and to present product scheme correctly and to establish a VMD Plan which can also contribute to sales promotion by providing infirmation and arranging Store Display efficiently for customers. Additionally, this is aimed to present an efficient and sensitive design process.esign process.

Generally part of museum collections are cycled exhibition space centering around preservation space, and that is a important mechanism of collections circulation in a museum. The reason why with a few exception most of collections have been lasting its life during over hundreds of years with adapting itself to natural features, so scheme of preservation facilities should be made up with understanding and analysis generic character of collections, and then establish proper temperature and huminity environment. So, this study is based on a fact that the collections' physical and chemical conditions vary in the relics a degree of transforatiov. And by making a suitable ganering environment, this gradual study is to provide planning factors for an architectural guide to make museum ganering environment organized and resonable.

The purpose of this study is in providing a systematic method for school building color scheme. This study analyzed the cases of color uses in domestic and foreign school buildings. The results from this study tells that the colors in school buildings should take into account the environmental, psychological and functional elements at the same time to effectively function as environmental color, effect color and induction color.

The mission of the TTC system is to acquire and process the telemetry data from the satellite and to provide mission planning and satellite control for the target stellite system. In this paper, the transmission scheme for the Tracking, Telemetry and Command(TTC) system of satelliteis described and determined according to the recommendation of CCSDS, and the channel characteristics are analyzed according to modulation method. Expecially, we introduced the concepts of carrier vs. telemetry data power ratio which causes the channel performance to degrade, and analyzed the effects of transmission performance according to the power ratio of carrier vs. telemetry data and the modulation index. The channel of the LEO TTC sytem is different with usual satellite communication system. So, we have generalized the link budget of TTC sytem for using the link budget of ground station well-known and proposed the determination method of modultion indices for improveing channel performance.

In this paper, a new intelligent moving target tracking and surveillance system basing on the pan/tilt-embedded stereo camera system is suggested and implemented. In the proposed system, once the face area of a target is detected from the input stereo image by using a YCbCr color model and then, using this data as well as the geometric information of the tracking system, the distance and 3D information of the target are effectively extracted in real-time.

Presented in this paper are a CAPP(Computer Automated Process Planning) scheme and a generating method of intelligent NC data for unmaned machining of mold die. Mold die surfaces usually have free-formed geometry of complex shapes. So it is easy to overcut the die surface and to overload the cutting tools. It takes tens of hours to prepare process plans and to generate NC data for each processes. Therefore a classification of unit machining operation(UMO) for mold die manufacture, a backward recursive capp algorithm and a generating method of intelligent NC data are presented in this paper in order to provide a unmaned machining architecture of mold die.

The purpose of this study is to investigate the functions of prefrontal lobe on the formation of conservation scheme of elementary students. In this study, 107 students of 4th to 6th grades were selected from the elementary school in Seoul area. As to the research,4 items for conservation logic test from GALT test sheet were used. The planning ability, inhibiting ability and reasoning ability were measured for the prefrontal lobe functions. About 30% of 4-6 grade students did not have volume conservation logic skills. The formation of conservations was not linear. Inhibiting ability was significantly different in level of conservation. And, conservation logic skills were significantly correlated with cognitive variables. Reasoning ability was significantly explained about 10% of the conservation logic in 4-6 grades.

This paper describes a methodology of mobile robot navigation which is designed to carry heavy payloads at high speeds to be used in FMS(Flexible Manufacturing System) without human control. Intelligent control scheme using fuzzy logic is applied to the navigation control. It analyzes sensor readings from multi-sensor system, which is composed of ultrasonic sensors, infrared sensors and odometer, for environment learning, planning, landmark detecting and system control. And it is implemented on a physical robot, AGV(Autonomous Guided Vehicle) which is a two-wheeled, indoor robot. An on-board control software is composed of two subsystems, i.e., AGV control subsystem and Sensor control subsystem. The results show that the navigation of the AGV is robust and flexible, and a real-time control is possible.
