The purpose of this study is to develope a prototypical unit design for the Information Resource Center(IRC) for K-12 schools in Korea. Literature from various sources were examined. A survey was administered to sixty-three elementary and middle schools in Korea. A case study was conducted to two elementary schools in Korea and one elementary school in Portugal. Design standards and prototypical unit design for the IRC were developed applicable to existing K-12 schools in Korea. The prototypical unit design suggested in this study optimize the needs of the students, teachers, and neighborhoods for the space of information, reading, consultation, graphic production, and group activities. The results of this study indicated that there needs consistent government educational policies, increased financial investment on computers and supporting media facilities, and partnership with the design professionals.

근리주구개념은 도시사회구조를 이해하는 기본적 틀로서 인식되어왔을 뿐 아니라 도시공원의 계획에 따르는 공원체계의 개발 및 도시민의 여가행동 규명에 중요한 하부체계로 사용되어왔다. 80년대를 전후하여 발표된 다수의 논문에서 보고되고 있는 도시공원의 낮은 이용사례는 공원의 소극적 관리 상황 뿐 아니라 계획 그 자체에 문제가 있음을 환기시키고 있다. 본 연구는 미국의 소 도시를 대상으로 지역주민에 의한 근린주구 개념을 파악하고 주민의 근린공원 이용실태를 분석하여 전통적인 근린 공원계획의 설정목표 및 기준상의 문제를 제조명하고자 한다. 연구결과 주민의 근린주구개념의 '동질성'의 사회경제적 기능주의 입장보다는 물리지형적 특성으로 기울어 사회학자 및 공원계획가의 근린주구에 대한 기본전제에서 벗어나고 있으며, 계획가에 의해 임으로 설정된 근린공원의 서비스 영역(0.8km 둘레) 내부에 위치한 주민들의 공원비용은 주민자신에 의해 도출된 근린 주구 영역이 공원의 포함여부에 커다랗게 영향받고 있음이 밝혀졌다. 본 연구는 근린주구의 사회학적 개념과 현상학적 접근방식의 일환으로 Cognitive Mapping 기법에 대한 정리도 제시한다.

We proposed a novel similarity measure using weighted difference entropy (WDE) to improve the performance of the CF system. The proposed similarity metric evaluates the entropy with a preference score difference between the common rated items of two users, and normalizes it based on the Gaussian, tanh and sigmoid function. We showed significant improvement of experimental results and environments. These experiments involved changing the number of nearest neighborhoods, and we presented experimental results for two data sets with different characteristics, and results for the quality of recommendation.

This study shows how community can support the work-family balance and stimulate efforts of community within it. For this purpose, community concepts are defined and its demands and resources are compared with those of work and the family, Furthermore, it will examine the conditions which individuals, couples and neighborhoods need for work since the family balance is examined through the family-friendly community index. Various examples of volunteer activities or movements within the community that will support the work-family balance of the neighbors are also demonstrated. Also, the alternatives fur healthy family support activities in Korea are suggested.

This paper proposes a method of solving a unit commitment problem using parallel tabu search (PTS). The TS is efficient optimization method using meta-heuristic. In this paper, to reduce the computation time for evaluating the neighborhoods, an evaluating method only on changed part and a path relinking method as diversification strategy are proposed. To show the usefulness of the proposed method, we simulated for 10 units system and 110 units system. Numerical results show improvements in the generation costs and the computation time compared with conventional methods. Numerical results show improvements in the generation cost and the computation time compared to previously obtained results.

The purpose of this study was to develop a measurement model for evaluation of residential environment in low-income families. Residential environment means the housing unit itself and neighborhoods and community characteristics. Based on the previous research on housing environment, six factors (comfortable environment in indoor and outdoor, facilities environment in complex and community, sociopsychological environment, management and economic environment) were selected to evaluate residential environment and to provided a foundation for exploring the multidimensional factors of this research. As s confirmatory study, an Analysis of Linear Structural Relationships(LISREL) was utilized to develop the model. Despite of some measurement errors, the goodness of fit of an overall model was acceptable. Facilities environment in complex and sociopsychological environment were the most important factors in residential environmental evaluation of the low income families. the findings showed that housing policies and programs to improve the quality of homes in low-income families seemed to be beneficial to improve residential satisfaction of the residents.

An 1-bit DPCM image coding method is presented. Our method is specially designed to reduce the slope overload which seems to be the major performance degradation factor in 1-bit DPCM. In the present algorithm, based on the classification of neighborhoods by its flatness, slope strength and direction, predictor and quantizer operate adaptively through switching action. Compared with some other methods by computer simulation, proposed method shows improved performance in image quality as well as in signal to noise ratio. This gain mainly comes from the reduced slope overload and seems large to compensate the increased complexity in prediction. As a post processing, Lee filter is used to reduce the granular noise subjectively annoying in flat region.

Drainage noise with making think about what they do disturbs neighborhoods live under source of noise. elbow pipe built in the house. the general elbow pipe has a rectangular elbow because of easiness when the plan set up or executing. therefore, free falling fluid impacts on the wall of the elbow pipe almost at one point. in this paper, to disperse the potential energy, the shock decentralizes from tiny area to large area. And It is considered how the characteristics change according to the noise of transformed shape of pipe, then researched the effectiveness of transformed pipe configuration.

Cohousing is communities balance the traditional advantages of home ownership with the benefits of shared common facilities and ongoing connections with your neighbors. It is characterized by private dwellings with their own kitchen living-dining room etc, but also extensive common facilities. These cooperative neighborhoods are one of the most promising solutions to many of today's most challenging social and environmental concerns. The purpose of this study is suggest planning direction to cohousing as alternative house. It focuses on the planning method through case study. The result of the study are summarized as follow ; Size of cohousing is 20${\sim}$50 family. Location of cohousing is urban. Type of house is detached house+row house. Size per family is 0${\sim}$15m$^2$. Common house makes up kitchen, dining-room living-room, guest room nursery room and so on.

Malodorous gases give discomfort and harm to laborers and residential neighborhoods and therefore, the removing odor materials emitted from plants and industrial facilities is important subject. The main ingredients of alkali odor are $NH_3$ and $CE_3SH$. The adsorption characteristics of odors were studied using four different activated carbon fibers(ACF) and active carbon(AC). Alkali odor was removed by using ACF impregnated with $H_3PO_4$ and $H_2SO_4$ and treated with $HNO_3$ and NaOH. The experimental result showed that ACF has a higher removal efficiency than AC. The adsorption capacity was increased with the impregnation and surface treatment, and $H_2SO_4$ was the best impregnant for the removal of alkali odor.
