This paper addresses a problem of machining route selection in multi-stage process with machine group. This problem is considered the subcontracting and the production in-house such as regular and overtime work. the proposed model is formulated as a 0-1 integer programming constraining the avaliable time of each machine for planning period and total overtimes. The objective of the model is to minimize the sum of processing cost, overtime cost, and subcontracting cost. To solve this model, a genetic algorithm(GA) approach is developed. The effectiveness of the proposed GA approach is evaluated through comparisons with the optimal solution obtained from the branch and bound. In results, the same optimal solution is obtained from two methods at small size problem, and the consistent solution is provided by the GA approach at large size problem. The advantage of the GA approach is the flexibility into decision-making process because of providing multiple machining routes.

This study is on the spacial flexbility of house. In the recent days, it is true that the qualitative aspect of residence rather than the quantitative one has emphasized. But the inhabitants of residence undergo adaptation problems to deal with changing needs constantly. Residence must be the place to satisfy inhabitant's desire to live and dwell. According to changes in family life cylce and personal demand, the flexibility in housing should be beneficial. This study attempts to solve relationships of these need changes and inhabitant's adaptation through the spatial flexibility. Throughout the process of main discourse, some theoretical backgrounds of housing are applied. And to introduce the flexibility of residential space, concepts of flexibility according to 'time' and 'spatial structure' are employed. In addition to functionality and comfort, living should provide a touch of humanity attuned to individual sensibilities. The purpose of this study is to suggest a method can move interior structure by the flexible planning.

As we have come to realize the problems caused by the modern civilization as well as the importance of the preservation of nature. Ecological building and urban design come to attract more attention. Therefore, the object of this study is providing the design factors and improving the design methods for the developments of ecological housing complex, harmonious with environment. Followings are the results of this study: 1. We need to turn to new trend-Ecological architecture which enables the co-exitence of nature and human being to come over the presence and face new decades. 2. Ecological architecture is based on energy-saving system and give people a healty and comfortable atmosphere. 3. In the city area, the house development should be undertaken to minimize the environmental problem through extremely high ehhiciency and technonogy. 4. We need a new development to preserve natural environment in the suburvan and small or medium city. 5. We have to develope the approach method, which is to maintain the frame of present ecological environment, to be in sympathy with geomorphology, to use the natural material in the rural community.

Importation of mass production of building elements with standardization are vital way for environment-friendly architectural planning, which it makes the lifespan of a building longer than normal with easier maintenance and remodeling. The advantage might be magnified here in Korea since typical types of apartment house are dominated in our construction market. For the purpose, a series of pre-manufactured window systems is one of the optimal elements to be prototype building modules. In the design process of the system windows, lots of consideration should be involved and they include aesthetics, thermal performance, noise reduction, airtightness, and so forth. A real survey on the ready-made window systems has been performed and its optical issue related to luminous peculiarity is what is of major interest in this study. In addition, technical review on more advanced window products and their adaptable potential for the integration with fundamental architectural design elements were carried out.

There are many research Papers and experiments indicating that the geomagnetic field affects the people and living organism. People grow up and build up most of their character through living in dwelling space and have relax and refresh at home. Creating healthy dwelling space is being considered very important in architectural planning and design for providing comfortable living environment and improving quality of life. Therefore. it is necessary to investigate the geomagnetic field and people's response in living space. In this study the vertical component(Z value) of geomagnetic field in detached houses was measured, evaluated by related evaluation criteria, compared with interview survey.

This study aims to establish the concept about a new approaching method dor remodeling in the planning step. also, this study sets up the way how to approach in a dimensional way by classifying the conceptual composition of the target housing as a method. The dimensional definition is as below. The one dimensional approach: the spot. the two dimensional approach: the line, the three dimensional approach: the apatial mass, the four dimensional approach: space + time, the n dimensional (multi-dimensional) approach: the space + time + emotion. The research findings are as follows : For the purpose of remodeling, the old housing should be viewed in the three dimensional shape and space. It is defined as multi-dimensional module method to design the shape and space of the target housing in a multi-dimensional point, considering the three dimensional space composition, the emotion of the user, the housing itself. and the time of the user.

In order to provide the basic data for planning of stairways design in elderly housing, the study of Ergonomics were exmined. 3 old women and 3 female subjects were tested: 1) The relations between blood pressure and pulse: In case of the old, blood pressure was the highest at 13 cm and pulse was the highest at 23 cm. But in case of the young, the former was the highest at 23 cm and the latter was at 13 cm. 2) EMG: According to the height of stairs, the significant differences on the statistics were not seen. 3) Riviewing that biological characters according to the finishing materials, in case of the old groups, they feel most stable, as they up the wooden stairs. While they feel very dangerous, as they up the stairs where carpet is on. In the biological characters according to the stairs heights and the finishing materials, the most stable conditions for the old are 15 cm-high-stairs, wooden. And even if the stairs used inside the house, the installment of the handrails at both side must be considered.
