The purpose of this paper are to find the relations between efficient faces and the regions of weights on the objective functions in Multi-objective Linear Programming. First, we define the region of weights corresponding to an efficient face, and find the changing pattern within the region of weights. Second, we find the eqution of the dimensional relation between the efficient face and the region of weight corrsponding to it.

In the descriptive studies investigating people's risk taking behavior, the most used experimental technique has been the simple lotteries which consist of only no possible outcomes. However, these simple lotteries cannot always be an appropriate representation of the real world decision-making situations, where three or more possible outcomes are frequently encountered. The purpose of the present study is to investigate people's risk attitude in various multi-branch lottery games.

The purpose of this study was to analyze the transition of housing facilities and the technicalization of the housing life through the newspaper advertisements between the 1970s' and 1990s'. The modernization on multi-family housing life since 1970s' was come true by functional equipments. Although the improvement on the material environments deteriorated the modernized life to the commercial uniformity.

This paper describes the fundamental investigations on the in-process monitoring techniques focused on Acoustic Emission(AE) based on analytical method. Experiments were conducted on a CNC lathe using conventional carbide insert tools under various cutting conditions. As the result of this study a suggestion is given about the multi-purpose use of AE-signals detected with a single sensor for the monitoring of tool wear, built-up edge and chatter vibration in turning process.

Much of the past work regarding repairable item stockage has concentrated on the development of models and policies for systems in steady state. However, there are important situations in which the transient behavior is most important. A dramatic example of this is the potential dynamic behavior exhibited by demands and service in the deployment of an Air Force squadron at the onset of a conflict. The purpose of this paper is to derive some probability distributions necessary for providing an integrated approach for a multi-echelon inventory system with nonstationary demands and service rates.

The Purpose of this study Is to investigate Open Housing design methods on multi-family housing in the Netherlands and Finland. This study is based on the several actual field survey through visiting eight sites in the netherlands and Finland. we found a lot of design items applied to the Holland and Finnish multi-family housing for Open Housing. Open Housing design items are user participation design, layout flexibility, finishes selection, flexible utilities, interior components and use of modular grid.

The Purpose of this research is to identify management systems that effect to multi-family housing resident's management satisfaction. This study used survey data collected by Korea Reseach Institute for Human Settlement(KRIHS) in 1003. The major findings were as follows: 1) Residents in compulsary management system evaluated housing management higher than ones in optional management system. 2) Quality of mainternanace management and residents' reliability of the representative committee influenced to residents' overall satisfaction of housing management.

The purpose of this study was to explore the attitudes about the management service charge in multi-family housing. Recently, increasing needs of urban families in residential housing management services were apparent in many studies, but the way that they charge for the management services was not dear. Research method was social survey with questionnaire from 484 residents and 84 housing managers of multi-family housing in Seoul and new town area. Research results showed that residents recognized the management services should be free of charge or imposed actual expenses, but managers recognized the management services as charged services. To provide efficient housing management services for residents in multi-family housing, human resources should be inputted. Therefore, this study suggested that the participation of residents in housing management service is recommendable as a way of lessen the economic burden of management service charge, but also to have an opportunity to interest in their community activities.

The purpose of this study was to find whether national identity, value orientation, cultural sensitivity influence Multi cultural competence of secondary school students. The significant result out of this research was that Multi cultural competence were different by its concerned variables. The results of hierarchical regression analysis reveal that changes to each of the models were checked by introducing a new group of variables in each stage. Then the influences of the concerned variables including national identity, value orientation, and cultural sensitivity on multi cultural competence were tested through the influence and significance of the variables and the changing explanatory power of the entire models.
