The purpose of this study was to determine the effect of a pleasantly designed interior inpro-spatial behavior. For pleasantly designed interior, the existing interior was remodeled through the change of finishing materials for major architectural elements such as wall, floor and ceiling, and changes of furniture and it's arrangement. Prospatial behavior was operationalized as seat arranging behavior and measured through the arranged condition and observable arranging behavior. Time-series design, one of quasi-experimental design was used. The data in this study were extracted from an existing field experimental research. One hundred forty four video tapes recorded during 6 months out of 2 years period ware used. In conclusion , the pro-spartial behavior change was a mid-term positive effect of pleasantly designed environment. In an environmental setting where pro-spatial behavior was most important, a certain time cycle to change the environment needs to be considered.

In this research, we explore how to manage the transition of technology generations considering incremental innovation of the existing technology generation. Firms can slow down decaying of the existing technology by continuous incremental improvements rather than introducing a new generation technology at the first time if the former strategy is better. We characterize optimal technology transition problem by setting up an optimal control model. The model which is originally designed and solved by Thompson(1968) as a ‘Machine maintenance problem’ has been cited to build the main body of our model. With this analytical model, we derive optimal ‘incremental innovation’ strategy which is considering transition to the next technology. Our analysis indicates that there exists an unique ‘stopping incremental innovation timing’. Before the point of time, the decision maker should make his effort at a maximum level to enhance the current technology. However from the stopping timing to the final time horizon where the new technology is introduced, it is found that not to invest to the current technology any more is optimal.

The objective of this study is to interpret a environmental-friendly plan factors of Korean traditional settlement used of existing classification system. The existing classification system framework is six environmental ecological ideas as the adaptation to the adaptation to the availability of land, the eco-space in village, the system of house, the cycling of material and the reasonable energy system, the water resources, prevention of environment pollution. Additional research was undertaken to verify the findings. Through the interpretation, it has been found out that Gu-Rim tradition village has been developed to an environmental ecological rational setting and has the meaningful elements for environmental friendly housing estates.

The usage of beam scanning type laser marker is rapidly increasing in the field of semiconductor equipment. A device called ″beam adjuster″ is employed to adjust the visible diode laser, which points the marking position for various setting. The device is very sensitive to manufacturing tolerance and assembly condition. Axiomatic approach has been applied to the design of the device. An existing design is analyzed based on the Independence Axiom. The existing design is found to violate the axiom. Two new designs are proposed to satisfy the Independence Axiom. The Information Axiom is utilized to evaluate the designs. A design is selected to have the minimum information content. The significance of this research is that a full cycle of axiomatic design is applied to a real engineering product.

By reviewing the current application of Environmental Fiscal Instruments in China, existing policy gaps and weakness, and the feasibility of using EFIs in China, this paper pointed out that the Chinese government faces an historic opportunity for promoting the development of a comprehensive environmental fiscal system. It is proposed that as far as possible the real economic and social costs of pollution and environmental degradation should be reflected in the prices charged for the use of environmental and natural resources. Chinese government should systematize existing environmental fiscal funds and policies, gradually setting up a framework for integrating environmental fiscal instruments into the public financial system.

The Korea-US dispute on telecom standards has shown the inability of existing trade rules that can be applicable to standardization policy in telecom services sector. It has entailed plenty of dissenting but unsolved trade issues, including legal jurisdiction over technical standards on telecom services and their compatibility with WTO agreements. Question remains how US will cope with this tricky trade puzzle. This paper points out that Korea-US negotiations on telecom standards have provided US with a momentum to think seriously over the necessity of further rule-setting on telecom standards, and FTAs are the rescue train for US to ride on for that purpose. That is to say, US is taking advantage of FTA as a means to promote its national commercial goals by creating trade rules, which seek to deprive its trading partners of regulatory autonomy in telecom standardization. Based upon the research output, it is very important for Korean government in the upcoming Korea-US FTA negotiations to ensure facilitating public policy objectives in telecom standardization as possible as it can, and not to adopt the provision of international standards in the existing US' FTAs.

In a heating control system, the indoor temperature controller transfers temperature signals inputed from the temperature sensor and the user to the valve controller. The valve controller recieves these signals then the valve controller controls the valve driving motor on two position control and controls the indoor temperature. When setting up a new valve driving motor from a long distance it is necessary to set up a new valve controller. But occasionary, due to construction, it is impossible to wire between the existing valve controller and the new valve controller. In this situation, the new and existing valve controllers can communicate via power line communication. In this paper it is proposed heating control system controls on two position control via power line communication.

본 연구는 사회복지사의 소진에 대해 그 유발 요인이나 과정에 집중해온 기존 연구들과 달리 의료사회복지사를 소진으로부터 보호하는 요인을 알아보기 위한 연구이다. 이를 위하여 7년 이상의 실무경력을 가진 의료사회복지사 중 동료들로부터 유능하다고 인정받은 10명의 사회복지사들을 대상으로 심층 면접을 하고 그 내용을 질적분석 컴퓨터소프트웨어인 Nvivo2를 활용하여 분석하였다. 그 결과 '전문적 역량', '성취와 보람', '일에 대한 확고한 가치와 신념', '좋은 팀워크', '개인적 자질', '구조적 뒷받침', '가족의 인정과 지원'의 소진보호요인들을 도출하였다. 이러한 결과는 그동안 소진연구의 부수적 결과로 다뤄져온 소진보호요인을 총체적으로 제시하는 것으로서, 의료사회복지사들이 다양한 기제를 활용하여 소진의 위험을 감소시키고 소진을 극복하고 있음을 보여주는 것이다. 이들 소진보호요인은 의료세팅이라는 특수성을 반영하고 있으며, 특히 전문적 역량의 개발 및 관리가 강조된다는 것이 특징적이었다.

This study analyzed visual-perceptual centrality as a measure to solve the confusion that might occur in visitor's movement in analyzing contemporary museums that have recently expand. Also, this study proposed a new methodology to understand the relationships of the occurrence and convergence of visual-perceptual power. The existing visibility graph analysis mostly ends up in identifying nodes corresponding to the physical environment of museums while the newly proposed visibility graph analysis is a methodology that can analyze the landmark on which the visual-perceptual power occurs and converges, by setting visible space elements as analysis variables, which showed a possibility to draw more reliable results in parallel to the existing analysis, and the results of this analysis are as follows. A public museum located in downtown has a limitation that it cannot but be multi-layered as a way to enlarge for the accommodation of a variety of programs on a limited site. Also, this study found that the problem of visitor orientation occurring in the multi-layer process was solved by a major space which was visual-perceptually void. Also, its types can be summarized into two types: One is setting parameter spaces (ramps, staircases, hallways) linked visual-perceptually to the major space and the other is solving the confusion of the visitor's movement by composing a simple exhibition space. In particular, it is judged that the type solving the confusion of the visitor's movement by composing a simple exhibition space also had a relationship with changes in the characteristics of the exhibited works by period. In addition, it was found that the entrance also appeared in two types: dependent type and independent type in the major space according to the characteristics of the major space.

본 연구에서는 양생온도변화에 따른 자기수축의 예측을 위하여 FA 및 SF를 치환한 시멘트모르타르를 대상으로 자기수축변화를 측정하고 이를 등가재령방법으로 해석하고자 하였다. 이를 위해 수화반응의 온도민감도를 고려하는 Ea의 변화에 따라 지수함수모델을 이용하여 자기수축 해석을 실시하였는데, 경화단계의 $E_a$를 이용할 경우 응결단계의 $E_a$를 사용한 경우보다 정확한 해석이 가능한 것으로 나타났는데, 이는 경화의 전단계에 걸친 수화의 온도민감도 영향을 반영한 $E_a$값에 기인된 결과로 사료된다.
