The purpose of this study is to suggest the improved methods for cost sharing in apartment remodeling projects. Case studies on apartment remodeling projects with different plan type were analyzed and compared. Cost sharing estimated by 'proportional rate method' shows similar results estimated by 'return on investment method' in case of similar area ratio of existing plan to remodeling plan. Otherwise cost sharing estimated by 'proportional rate method' shows great differences comparing the results estimated by 'return on investment method'. Although return on 'proportional rate method' is widely used, it is not proper to estimate cost sharing when each householder's contribution for the project varies, such as considerable differences area ratio of existing plan to remodeling plan. Improved cost sharing method is needed taking into account project contribution and characteristics.

The purpose of this study was to identify current housing status and housing awareness such as housing values, satisfaction, and preferences among households with one child. Data were obtained from a questionnaire completed by both husbands and wives living in metropolitan area and aged between 25 and 45. Selected variables were the age, education level, and employment status of housewives, ideal number of children, monthly income, plan to give birth, and so on. Using purposive sampling method, five hundred questionnaires were administered and 360 questionnaires were analyzed. In accordance with the questions related to housing values, housing satisfaction of respondents was examined. In order to compare the housing values, preferences, and satisfaction among diverse variables of respondents, mean, t-test, F test, Duncan's multiple range test, $x^2$ test, and factor analysis were used. The major findings of this study are as follows: First, there were significant differences in current housing type, tenure type, and floor area according to housewives' age, education level, monthly income, and plan to give birth. Interestingly, households not having a plan to give birth in the future were living in larger house than the households having a plan to give birth. Second, housing values of households with one child were divided into 4 factors-environmental comfort, economy and convenience, social status symbolism, and adequacy of space planning. Items related to privacy showed the biggest difference between housing values and housing satisfaction. Third, most of the respondents wanted larger house than current housing. However, the need for quality of housing including floor area and amenities was significantly higher among households not having a plan to give another birth than households having a plan to give birth in the future.

The purpose of this study was to find out the residents' consciousness of the unit plan on condominium apartment and to contribute to develop a condominium apartment unit plan in Daejeon City. This research was performed by a questionnaire survey method, 464 data was collected from apartment residents lived in about $85\;m^2$ unit with 3 rooms and the apartments was limited to the complexes within 1-4 years of the length of building at Yuseong-gu and Seo-gu. By analyzing those data, findings are as follows: 1) Residents thought living room, kitchen and bathroom were importment space in a unit plan. They needed a storage function in an entrance and a intermediate room, and Anbang(mater bedroom) so did. 2) L-DK plan type was very popular and the type of front DK with L on the floor plan was preferred. This was unique results. 3) Sub-kitchen was needed for a refrigerator of Kimchi, the location of it was related to a main kitchen and a utility. the third room was needed for library, home office and storage space. 3) Bath-tub in An-bang and showe-booth in public bathroom was preferred. This was same to the popular trend of Korean condominium apartment. 4) The enlargment remodeling of balcony was showed livingroom balcony or personal bedrooms at the time of occupancy. They needed the balcony near a kitchen or an utility to equip a storage facility. Additionally, residents were preferred to their taste rather than a choice of interior concept package services.

The aim of this paper is to study on the background and the reasons of the uniformity of housing type and planning, and to find ways of coping with the related problems, focusing on the uniformity of apartment housing and it's excessive typical planning. In this process, I try to take suggestive hints from the case of Japan which already made an issue of uniformity of housing type and promoted the handling measure for the problem in a national level. The result includes that supplied apartment housing in Korea occupies about 80% of total housing supply each year, and the reasons for the increased apartment housing supply are attributed to many interactive influence factors. One of the influence factors is ascribed to mass housing system where many academic theories have supported the system under the interdisciplinary cooperation. In the case of Japan too many supplied condominium housing provoked the uniformity problem, however, the establishment of HOPE plan and a special association board oriented to the study of regional housing planning under Architectural Institute of Japan have considerably relaxed the uniformity problem.

A surface mount device (SMD) assembles electronic components on printed circuit boards (PCB). Since a component assembly process is a bottleneck process in a PCB assembly line, making an efficient SMD plan is critical in increasing the PCB assembly line productivity. Feeder assignment is an important part of the SMD plan optimization. In this paper, we propose a feeder re-assign improvement algorithm for a specific type of SMD machine with a piano type multi-head gantry. Computational results on some real-world benchmark data sets show the effectiveness of our proposed algorithm.

The purpose of this study was to analyze the residential preferences, the type of house, the size of living space, and the region for later life and contributing factors to their housing plan. The sample in this study consisted of 572 aged couple living in Korea. Statistics employed for the analysis were frequencies, means, X2test, logit analysis and multiple regression. The results could be summarized as follows. They preferred 31.2 pyung as living space, the single detacted house(81.1%) and living in middle-small cities or rural area. The present living space, present living area, satisfaction of economic status had significant effects on the living space in later life. Those who had a plan to live in the single detached house were affected by husband's educational attaintment, the type of present house, present and future living region. And the factors affecting furture living region were present living region, household income, household expenditure, total asset and preferred housing type. The affecting factors were different from future residential preferences by occupation and health status.

In this paper, the maximum likelihood estimators for parameters are derived under three step-stress accelerated life tests for Type-I hybrid censored data. The exponential distribution and the cumulative exposure model are considered based on the assumption that a log quadratic relationship exits between stress and the mean lifetime ${\theta}$. The test plan to search optimal stress change times minimizing the asymptotic variance of maximum likelihood estimators are presented. A numerical example to illustrate the proposed inferential procedures and some simulation results to investigate the sensitivity of the optimal stress change times by the guessed parameters are given.

The purpose of this study is to clarify the actual conditions of external space of middle and high schools in Gyeongnam Area. This article discuses about the characteristics of the external space and the site plan type of 49 middle and high schools in Gyeongnam Area. The result of analysis about site plan type, composition state of external space and area ratio of its composition of each middle and high school facilities are as follows: In facilities arrangement of middle and high schools, it shows diverse forms of arrangement from existing uniform straight type, however, most of schools do not being against the simple in their external space. Especially, for the area is small in the composition of external space, a playground is only under $50m{\times}80m$ and outdoor learning space or resting space is not secured sufficiently. Therefore, it requires an expansion of space size and facilities for the change of school life outside class.
