In this paper, we propose an example of designing and constructing a roof-type solar power plant structure equipped with a Pseudo-BIPV (Building-Integrated Photovoltaic) shape suitable for use as a roof of a small warehouse with a sandwich-type panel structure. As the characteristics of the roof-type solar power generation facility to be installed in the small warehouse proposed in this study, the shape of the roof is not a general A type, but a right-angled triangle shape with the slope is designed to face south. We chose a structure in which an inverter for one power plant and a control facility are linked by grouping several roofs of buildings. In addition, the height of the roof structure is less than 20 cm from the floor, and it has a shape similar to that of the BIPV, so it is building-friendly because it is almost in close contact with the roof. At the same time, the roof creates a reflective light source due to the white color. By linking this roof with a double-sided solar panel, we designed it to obtain both the advantage of the roof-friendliness and the advantage of efficiency improvement for the electric power generation based on the double-sided panel. Compared to the existing solar power generation facilities using A-shaped cross-sectional modules, the power generation efficiency of roofs in this case is increased by more than 11%, which we can confirm, through the comparison analysis of monitoring data between power plants in the same area. Therefore, if the roof-type solar structure suitable for the small warehouse we have presented in this paper is used, the facilities of electric power generation is eco-friendly. Further it is easier to obtain facility certification compared to the BIPV, and improved capacity of the power generation can be secured at low material cost. It is believed that the roof-type solar power generation facility we proposed can be usefully used for warehouse or factory-based smart housing. Sensor devices for monitoring, CCTV monitoring, or safety and environment management, operating in connection with the solar power generation facilities, are linked with the Internet of Things (IoT) solution, so they can be monitored and controlled remotely.

This research categorized EIA target highways into following three types in order to minimize non-point source pollution from highway runoff. 1. Big drainage basin. 2. Small drainage basin. 3. Bridge section. The Natural, Filter and Swirl-Type devices were evaluated in terms of removal efficiency of TSS, BOD, COD, T-N, T-P, compatibility of site selection, economic feasibility, and maintenance convenience through which the final BMP was selected. According to the removal efficiency result, the area of Big and Small Drainage basin and bridge section had higher removal efficiency with natural facility than that of the Filter or Swirl-Type device. To make appropriate selection of highways'BMP for non-point source pollution, this study will aim to contribute to building more environmentally friendly highways by proposing the selection process that is made of 5 stages. 1. Selecting the target drainage basin. 2. Selecting the land for the mitigation facility. 3. Analysing the ease of maintenance. 4. Technically evaluating each installation. 5. Evaluating the effective implementation methods.

최근 해양 시설물용 복합 발전 시스템 개발에 관한 많은 연구가 수행되고 있다. 일반적으로 해양시설물에 사용되는 독립형 전력 공급 시스템은 날씨에 상당히 많은 영향을 받게 된다. 이러한 전력 공급시스템의 효율성을 높이기 위하여 다양한 스위칭 알고리즘을 이용한 충전 기법이 연구되고 있다. 본 논문에서는 다중 레벨 방식을 적용한 전력 시스템의 충전 방식을 제안하고 실험을 통하여 결과를 제시하였다. 다중 레벨 방식의 충전기법을 시뮬레이션한 장치의 실험 결과와 기존에 사용 중인 전력 공급 시스템의 실험 결과를 비교하여 나타내었다. 그 결과, 다중 레벨 방식의 충전기법을 이용하는 경우에 기상 조건에 따라 충전 전력은 5~11%, 충전 가능 시간은 7~47% 정도 향상되었음을 확인하였다.

The purpose of this study is to provide an remodification method for elementary school complex facilities in Seoul Metropolitan city. This study analyzes the questionnaire survey for 568 entire elementary schools and the questionnaire survey for school facility complex project operated 44 elementary schools. Then the result of this study was deduced from the comparison between the 568 entire survey data and 44 survey data in terms of the cognition of school facility complex project, the required type of facility and the problems of complex facility maintenance and operation. Four major findings were revealed as the result of research. First, there is a very high agreement with the school facility complex projects. Second, it was need that the process of planning and design was remodified to enhance participation of parents of students and local residents for selecting an appropriate complex facility. Third, education environment and student safety should be protected from any other school facility complex environments. Fourth, an agreement and regulation is needed for more effective maintenance and operation of school complex facilities.

In the location science, environmental effect becomes a new main consideration for site selection. For the unwanted facility location selection, decision makers should consider the cost of resolving the environmental conflict. We introduced the negative influence cost for the facility which was inversely proportional to distance between the facility and residents. An unwanted facility location problem was suggested to minimize the sum of the negative influence cost and the transportation cost. The objective cost function was analyzed as nonlinear type and was neither convex nor concave. Three GRASP (Greedy Randomized adaptive Search Procedure) methods as like Random_GRASP, Epsilon_GRASP and GRID_GRASP were developed to solve the unwanted facility location problem. The Newton's method for nonlinear optimization problem was used for local search in GRASP. Experimental results showed that quality of solution of the GRID_GRASP was better than those of Random_GRASP and Epsilon_GRASP. The calculation time of Random_GRASP and Epsilon_GRASP were faster than that of Grid_GRASP.

The purpose of the study is to propose a basic data for the performance of related research and work tasks, along with an understanding of the Chinese mental healthcare facility type and support system. Furthermore, it will show a lack of current function management as the changes of mental health concept and demand for services increases, and it is intended to provide implications for the construction of mental health facilities. Methods: This study was conducted by a research on law and regulation of China's mental healthcare delivery service system and mental healthcare facility. The analyzed data are the national standard GB, the optional national standard GB/T, the building construction standard JGJ, and the report issued by the Health Planning and Development Committee. Results: At present mental healthcare facility construction in China is in the period of rapid development and it exposes the layout of medical facilities, which is not currently reasonable and the service does not reach the designated position and so on.

Simulation was conducted using TRNSYS to evaluate the thermal performance of a facility. This facility has a condensing-type heat exchanger which is able to recover the latent energy for the purpose of reducing the heating energy in winter. The boiler and chiller are selected based on the annual peak loads and controlled to maintain the facility at the set temperature of 14~$17^\circ{C}$. Supplied energy by the boiler and recovered energy by the heat exchanger were calculated as a function of number of pass through heat exchanger, kind of fuel and hot water velocity. Simulation results show that about 20% of the total heating load can be recovered by the heat exchanger and the amount of latent heat is increasing with the number of pass. This means that the efficiency of the waste energy recovery system can be increased by using a condensing-type heat exchanger rather than a traditional sensible heat exchanger.

Since the Standard Design Guide in 1962 and "School Facility Facility Standard Regulation" established in 1969, the elementary school facility in Korea has been amended and complemented. The modern pilot school was started in 1991 and every elementary school facility has been designed based on the modern elementary school from 1994. At present, 8 out of 28 closed schools occurred in the downtown area in Daegu. One of them is located in rent and 7 are used by themselves. The rest 20 schools are located in Dalsung-gun and most of them have old buildings of straight plane shapes built in 1940s. The purpose of this basic study is to pursue the changing process of closed schools based on policy changes of curriculum and to seek the qualitative change when using closed schools. In addition, it is to prepare the using measures when the school close is occurred in the downtown area in the future by classifying and analyzing plane types according to their types.
