Purpose: This study was done to evaluate the operating status of community-based home health center for revitalization of the centers. Method: In this study performance data including organization plan and service utilization plan were evaluated according process theory. Target of evaluation was the community-based home health care center. Results: The vulnerable part of the organization was the information system and financial resources. The home health center introduced PDA (Personal Digital Assistants) in 2005, however home health care nurses did not make full use of it. This service received full support from Seoul city and local government and there were no other sources of income. The vulnerable part of service utilization was service expansion and standardization due to vulnerability of organizational aspects. Conclusions: The home health care center provides high quality services to underprivileged people. In the future, these services should be provided with equity for continuous health care for this population.

Recently, As the construction industry has been growing in size and complexity, the utilization of BIM is increased to improve effective management and integration of information. BIM (Building Information Modeling) has been focused on architecture, engineering, construction and maintenance field. However, There is a lack of BIM research on Interior Architecture fields. So It needs more research in this area. Through a previous study that review on BIM applicability of building interior design, this study propose a process of Plan and utilization planning for building Interior design based on BIM. As a result of this, BIM library, 3D simulation, automation for quantity estimation and information management can improve efficiency of business and help decision making for plan.

The primary purpose of this study is to suggest the policy for the effective utilization of empty classrooms in elementary school. The empty classroom in this study means the classroom that is not used now since the number of students decreases, but can be usable for other needs in future. The following results are obtained through this survey; 1) about forty percent of classrooms are empty classrooms, 2) the ratio of empty classrooms is higher in urban area than rural area, 3) the smaller the size of classroom is, the higher the ratio is, and 4) 56.5% of the schools have one to three empty classrooms and 30.0% have four to six empty classrooms. In conclusion it is suggested that 1) the reutilization plan of empty classrooms be established according to particular situation of each school, 2) the government develop the guidelines for reutilization and administrative procedures for renewal, 3) the reutilization plan be established from the view point of the quality improvement of schooling, and 4) the enlargement and rearranagemt of learning space be considerd when reutilization is planned.

본 연구에서 일반철도의 선로이용율의 범위인 60%를 검토하여, 이용가능한 시간과 이용 불가능한 시간을 수치화 하였다. 또한 선로이용율을 변화시키는 요소인 선로유지보수시간에 대한 계산과 적정한 추정시간을 분석하였다. 적절한 철도운영계획과 원활한 시설유지보수를 통한 열차의 안전을 보장하여야 한다. 동시에 매일 연속되는 열차Dia의 원상회복력도 운영계획에 반영되어야 한다. 이런 사항들을 고려하여 보유 중인 기계장비와 국가철도망에 대한 자료를 활용하여 유지보수작업시간 산출방법을 개선하고, 열차지연에 대비한 여유시간을 확보하도록 검토하였다. 결론적으로 일반철도의 선로이용율과 선로유지보수시간 구성요소를 함께 수량화하여, 선로이용율은 60% 내외가 타당함을 증명하였다.

This study aims to find the perception and utilization of the citizen about the dryness watch warning (DWW) among special weather reports. For this we have made up a descriptive questionnaire including the perception, utilization of special weather reports. Using the SPSS 17.0 program, descriptive statistics, t-test, ANOVA and Scheffe test were used to analyze the collected data. The results are as follows; The perception of DWW is measured by 4 point Likert scale and the average is $15.97{\pm}3.70$ (percentile=57.0). This value shows that the awareness level is not that high and according to the occupation, college students show the lowest awareness and housewives show the highest awareness. According to the age, the teens and twenties show the lowest awareness and fifties and sixties show the highest awareness. Although the perception of the teens and college students are rather poor, there were many positive answers that it is necessary to establish the advanced disaster prevention plan according to the questionnaire about the utilization of DWW. Therefore, if we come up with an effective plan to improve the perception than we can expect a large-effect in terms of fire and forest fire prevention. The perception of DWW can be improved by providing weather information and weather related education program on TV or internet which have the high level of preference. Also, it is necessary to provide online and offline program of advertising education and disaster management education through the weather forecast bureau which is the host organization of delivering weather information.

The government has implemented operating the bus information terminal (hereinafter, 'BIT') to use by building it at a major bus station to solve the problem of traffic congestion. Busan Metropolitan City has been continuously expanding the installation of 'BIT' since 2003. However, there are few research on the factor to use and satisfaction survey on 'BIT' from the perspective of the users. This study, in an effort to inquire into the 'BIT' utilization factor and its vitalization plan, conducted a face to face survey of 172 citizens who had the experience in the 'BIT'. The result of the data analysis showed that usability, convenience, and availability were the critical factors for a BIT use. In addition, the general intention to use 'BIT' was found to be very high as much as 90.7%. The contributions of this study are as follows. The academic contributions is that it proved the relationship between usability, convenience and the intention to use suggested by the information technology acceptance model is supported even in case of 'BIT.' For the practitioners this study provides ground data for a local government to make a plan of a BIT extension.

In this paper, we propose a linear programming model of supply planning process for the supply chain collaboration strategy of a company. The amount of its supplying quantity relies on outsourcing suppliers heavily. Conversely, the revenues of those suppliers are highly dependent on the supplying quota from the supply network planning of the company. In order to keep the supply stable through collaboration, the company builds such a policy to guarantee the fairness on revenue between the supplies. For this, the supply network plan should keep the capacity utilization ratio even for all the suppliers. But the production capacities are different and the distribution of molds is disproportional through suppliers, so the supply network plan is not easily established with simple arithmetic processes. Therefore, we developed the linear programming model with those target function and constraints minimizing the costs for holding inventory and penalty of delayed delivery, simultaneously guaranteeing the even capacity utilization through suppliers. The proposed model has been applied to real case and the evaluation for the planning result from the model would be followed in order to make sure that our model guarantee on extracting the supply network plan subordinated to the policy. Also we mention about further studies for improvement of the model.

The purpose of this study is to identify the problems of the currently used 3D spatial information utilization system to realize a more accurate landscape and to establish a user-oriented environment to improve the utilization plan for future landscape evaluation. As citizens' interest in urban landscapes with strong public characteristics increases and the speed of urban development also increases, more suitable simulation methods for landscape management are required. Nevertheless, there are many cases of inconvenient correction according to development changes along with many errors in various steps for creating landscape simulation. Therefore, in performing landscape deliberation according to development, it is necessary to create more accurate and efficient landscape simulation, and if changes occur after the initial deliberation, a process that can quickly and conveniently correct and supplement data is needed. In addition, it is necessary to create landscape simulation so that the created modeling source can be used by being compatible with other application programs. In this study, a method of constructing a more accurate and efficient simulation at the time of initial deliberation and a method of creating a landscape simulation model for rapid response to a plan that is changed at the time of re-deliberation are described.
