South Korea has long been without major earthquakes. But 317 public facilities have been damaged by Po-Hang earthquake. Among them, 103 educational facilities suffered 25.6 billion won worth of damage. This is the most damaging of public facilities. The earthquake damage was mainly centered on non-seismic retrofit educational facilities and masonry architectural wall systems installed on the outer walls of buildings. Therefore, the purpose of this study is to develop a filling material that can be applied to the non-seismic retrofit of masonry architectural wall systems installed on the outer walls of educational facilities. To achieve the objective, first, set the filling material requirements. Second, set the sequence model of experiments and prepare for the experiment. Third, after the experiment, analyze the results obtained through the experiment. Forth, the optimal filling material is selected by comparing the analyzed results with the requirements. As a results, E-S-X sample using epoxy resin were selected for the seismic retrofit of masonry architectural wall systems in educational facilities. In the future, this study can be used as a basic material for developing seismic reinforcement methods guidelines in domestic existing educational facilities.

This paper is about the economic analysis of the replacement of electric facilities in the production facilities. As the interest of energy is increasing, the efficiency of facilities become more important. So, in this paper, we diagnosed facilities, especially electric motors, in the plant and calculated the operating efficiency, power loss with the load factor. And when we replace these facilities into high-efficiency motors, we also calculated new energy efficiency, energy loss and economic analysis through capital recovery factor. As a result, we economically proved that using high-efficiency motor is more beneficial than using non-high-efficiency motors in the model process.

We purpose a decision model to select the optimal facilities for the Decision Making problems with multiple characteristics(nominal-is-best characteristics, larger-is -better characteristics, smaller- is -better characteristics). Using this model, concept of the loss function is used in this comprehensive method of for select the optimal preferred facilities. To solve the issue on the optimal preferred facilities for multiple characteristics, this study propose the loss function with cross-product terms among the characteristics and derived range of the coefficients of the terms.

The purpose of this research is to analyze layout characteristics of community facilities for children in apartment housing, to survey parents, who can understand their children best, in regard to the features of using community facilities for children and their satisfaction level, and eventually to provide basic materials for planning future community facilities for children. For this research, seven apartment housing with over 500 households in Dongtan New City were selected as trial apartment housing. The findings of this research are as follows. First, the findings of the survey of the community facilities for children in the apartment housing showed that the facilities could be categorized into playgrounds, playrooms, libraries, and kindergartens/child care centers. Second, according to the survey, the layout types of community facilities for children showed to have various types such as a central type, a concentration type, a balanced distribution type, a near-entrance type, and a combination type. As for their elevation types, they showed to have a stand-alone type, an aboveground type, and an underground type. Third, As a result of the survey on the usage of the community facilities for children by category, most respondents indicated they were using playgrounds and libraries. On the contrary, the users of indoor playrooms and kindergartens/child care centers were concentrated among infants and kindergarteners, and thus the use rate appeared to be low. Fourth, the satisfaction levels of using community facilities for children appeared to be high in general. Particularly, the satisfaction level for kindergarten/child care centers appeared to be higher than those of other facilities. On the contrary, the satisfaction level of libraries appeared to be low.

On the basis of 2017, the cremation rate in capital area was 89.0% which was much higher than the national average cremation rate(84.6%). Due to the short supply of cremation facilities in accordance with the increased number of cremation cases every year, the demand for cremation from the residents outside of the jurisdiction area with no cremation facilities was increased, so that the residents in the jurisdiction area had difficulties in using the Online Cremation Reservation Service in Funeral Information System. Thus, this study aims to make suggestions for policies as follows.First, on the basis of 2017, the demand-supply rate of cremation facilities in Gyeonggi-do was 139.4%, which means that the demand for cremation largely exceeds the ability to supply cremation. Therefore, first, in the level of Gyeonggi-do, the expanded supply of cremation facilities should be induced by carrying forward policies such as financial support to the basic local governments installing cremation facilities and expansion of incentives support to the residents of regions attracting cremation facilities. Second, it would be necessary for the central government to expansively conduct the support standard price and government subsidy rate(70%) for the new construction of cremation facilities and the establishment of cremation furnaces. Third, there should be some policies to decrease the inflow of residents outside of the jurisdiction area by raising the fee for using cremation facilities outside of the jurisdiction area of Seoul Metropolitan City and also expanding the application of a sliding scale of cremation hours.

The purpose of this study was to examine the relations between using experience of environmental education facilities and attitude toward environmental education in parents who have elementary students in Seattle, U.S. The findings of this study represented that elementary parents have a great understanding about the importance of environmental education. Parents have a strong agreement with the necessity of environmental education in childhood. This research also found the differences between grades and facilities for environmental education in expected effect on environmental education and desirable fields of environmental education. The awareness of the importance of environmental education increased according to frequency in using environmental education facilities. In addition, the more the experiences of using various environmental education facilities, such as museum of natural history, science museum, arboretum, and aquarium expanded, the more educational effects positively increased over time.

The aimed to development general management system that can manage diverse facilities of city using RFID. Defining data format of items in each management, type and code for the urban facilities, the researcher designed database of urban facilities through the process of establishing logic model and data modelling. By inputting designed database into RFID Tag of each urban facilities and using RFID Reader and PDA, the researcher developed system that can efficiently manage the basic attributes and information and management information of urban facilities. Further, it was found that the characteristics of RFID Tag and GPS should improve the optimal hardware combination and PDA performance for the surrounding environmental influence and system performance.

In the future, the sorting machines will be taken charge of the most part of the letter sorting operations. At present, in order to deliver the sorted letters by the next day, many labors are intensively committed in the letter sorting operations. This research analyzes the problem of the facilities layout in registry department of mail center. It presents an improved design of facilities layout in comparison with several alternatives including the current layout using AutoCAD and FactoryCAD. It presents the optimized facilities layout using the algorithm which is embedded in the FactoryOPT. By the result of this research, we expect that the productivity of sorting letter will be improved and the related total labor cost will be minimized.
