The most of former schools facility have been planed and constructed with cement liquid waterproofing which is moth to be desired fir behavior of structure. However. It cause to decline safety for structure and also increase repairing cost that by leakage to behavior for thermal effects, Moreover, It is necessary for establishment fundamental counterplan of maintenance for schools facility to improve educational environment in budget support and proper diagnostic tech. and evaluation, repair reinforcement. In present paper, Firstly, we analyze out leakage and defect of schools facility of ㅇㅇ district office of education. Secondly, suggest the proper diagnostic tech. as leakage factor to develope efficiency of using space for durability and safety from leakage with suggestion the proper diagnostic.

In this paper, a procedure using a genetic algorithm (GA) and a heuristic local search (HLS) is proposed for solving facility rearrangement problem (FRP). FRP is a decision problem for stopping/running of facilities and integration of stopped facilities to running facilities to maximize the production capacity of running facilities under the cost constraint. FRP is formulated as an integer programming model for maximizing the total production capacity under the constraint of the total facility operating cost. In the cases of 90 percent of cost constraint and more than 20 facilities, the previous solving method was not effective. To find effective alternatives, this solving procedure using a GA and a HLS is developed. Stopping/running of facilities are searched by GA. The shifting the production operation of stopped facilities into running facilities is searched by HLS, and this local search is executed for one individual in this GA procedure. The effectiveness of the proposed procedure using a GA and HLS is demonstrated by numerical experiment.

Storage method is one of major measures for reduction of CSOs pollutant loads and several projects have been done nationwide. But systematic analysis of intercepting capacity has not been studied to determine optimum size of storage facility. In this research, not only storage volume but also intercepting capacity which means flow capacity from intercepting facility to CSOs storage facility was studied and optimum sizing method for storage facility was proposed. The result shows that pollutants reduction efficiency can be increased significantly by increasing intercepting capacity and it might reduce storage volume and total construction costs. Intercepting capacity for the study area was evaluated and it was shown as equivalent to 83 % probability rainfall intensity.

Understanding the antecedents of high public usage of national R&D facilities is a critical issue for both academics and facility managers. Previous researchrelated to general service management has identified service quality and user satisfaction as important antecedents of reuse and recommendation intention. The current paper reports findings from a survey which looked into the impact of service quality dimensions and user satisfaction on reuse and recommendation intention in the field of R&D facility public usage. Findings indicate that service quality appears to be linked to user satisfaction, and user satisfaction to be linked to reuse and recommendation intention. Findings also indicate that user satisfaction played as a mediator on the relationship between service quality and reuse/recommendation intentions in R&D facility public usage domain.

Facility location planning (FLP) problem is the strategic level planning in supply chain. The FLP is significantly affected by the operation time of each facility. In most of the FLP researches, operation time of facility has been treated as a fixed value. However, the operation time is not a static factor in real situations and the fixed operation time may lead unrealistic FLP. In this paper, a mixed integer programming (MIP) model is proposed for solving the 3-stage FLP problem and operation times are adjusted by the results from the simulation model and an iterative approach combining the analytic model and simulation model is proposed to obtain more realistic operation plans for FLP problems.

Being rapidly increased in population of the Elderly supporting of the Elderly is no longer family's and personal problems. It is social issue that demand measures by the government. Though many kinds of welfare policies for the Elderly have been established, it is not sufficient both in quality and quantity. In order to support residents of region, welfare facilities which based on community welfare have been supplied. This study is targeted on health facility for the elderly of Japan. First purpose, it is to acheive basic information about health facility. Second purpose of this study is to basic data for planning of facility.

A tree structure model has been proposed for representing the unequal-area facility layout. Each facility has a different rectangular shape specified by its area and aspect ratio. In this layout problem, based on the assumption that the shop floor has enough space for laying out the facilities, no constraint is considered for a shop floor. Objectives are minimizing total part movement between facilities and total rectangular layout area where all facilities and dead spaces are enclosed. Using the genetic code corresponding to two kinds of information, facility sequence and branching positions in the tree structure model, a genetic algorithm has been applied for finding non-dominated solutions in the two-objective layout problem. We use three kinds of crossover (PMX, OX, CX) for the former part of the chromosome and one-point crossover for the latter part. Two kinds of layout problems have been tested by the proposed method. The results demonstrate that the presented algorithm is able to find good solutions in enough short time.

The purpose of this study is to suggest fundamental data for design and planning of university dormitory through the survey of facility condition and resident's satisfaction. The scope of this research is limited to the period from late 1980's to early 2000's. The University Dormitories in Jeollanam-do and Jeollabuk-do are selected as subject. The result of this study is as follow. 1) Even though dormitory's total area is increased than the past, user's satisfaction is still in low level. It's necessary for user to fit a space to life pattern and the difference of human. 2) As a result of comparing of the sexual difference, most men are more active than women in using facility and practice 3) Not only a part of facility but also a part of operation is important element in satisfaction.

One of the major drawbacks of the existing facility layout methods is that most of them were developed based on pre-defined cost functions, and therefore fail to cope with the dynamic aspects of modern manufacturing systems. Another drawback is that due to the poor representation capability of the block diagrams, they are not able to convey the sufficient information needed by facility designers. In this paper, a system for solving facility layout problem considering these matters in cellular manufacturing environment is proposed and implemented using GA approach with embedded simulation module and virtual reality technologies.
