In this paper, we analyzed the present status of the safety manager and safety assurance aspects through a complex analysis on the operational aspects, marketability and electrical safety aspects of photovoltaic power generation facilities. In the analysis of the equipment status, we analyzed the status and operated status of the installed PV system in Korea and the correlation between the safety manager and the accident. In addition, we analyzed the direction of the ESS through the analysis of the installation status of the ESS, and applied it to the interpretation part of the ESS associated with the solar power generation. The status of the electric safety manager can be used to analyze the data for selecting the electric safety manager by capacity by analyzing the accident status, the electric safety manager operation status, the safety management time by capacity, and the electric safety manager market.

This study was conducted to investigate the correlation between golfer satisfaction and the diverse variables of golf course design and operation from the golfer's point of view. It was intended to reflect the various expectations and desires of golfers regarding golf course design and operation. The study was conducted on 119 golf courses in Korea, and 309 questionnaires were collected and analyzed. Results are summarized as follows. First, the most influential operational service variables on golfer satisfaction were "appearance of the golf courses", followed by "staff service", and "greens fee". Second, the most influential course design and maintenance factor variables on satisfaction were "course maintenance status", "teeing ground characteristics", and "landscape architecture". Third, based on the results shown in these two areas, a linear regression analysis was conducted to synthetically explain "operational service" variables and "course design and maintenance" variables. As a result, it was found that the explanation power of the synthetic model was 36.5%, and a model appropriateness test was found to be positive. As a result of a regression analysis of the synthetic model affecting golfer satisfaction, the most influential factors were "course maintenance status" followed by "landscape architecture", "tee characteristics", and "staff service". Regarding coefficient values, course maintenance status had an influence of 21.8% followed by landscape architecture at 20%, tee characteristics at 17.7%, and staff service at 15.5%. These results were found to be different from preceding studies that emphasized golf course operational service.

Development and diffusion of a new and renewable energy are acutely required at domestic energy actualities to be inferior as industrialization is accelerated, and use of information electric appliance is increased rapidly. For the diessemination and practical use of new and renewable energy, this paper presents an unified security management system that is efficiently able to acquire operational status date and control distributed generation facilities. Also, the unified security management system is suggested to protect gathered operational status date from unpredictable problems such as computer virus, spy ware, and any other network problems.

The amount of cargoes by cargo vessels has increased tremendously during the last decade due to the great growth of korea economy. But in spite of this trend, there is rarely the substantial analyzed on the operational status of coastal shipping. In this paper, the characteristics of seaborne cargo and traffic flow of coastal shipping surveyed in detail through the statistical and the origintain and destination (O.D) analysis. Also, the basic ship's tonnage of coastal shipping representing the minimum tonnage which is capable of carrying the given seaborne cargo is suggested through the computer simulation using the data of 1985 year. The results are as follows; 1) the about 80% of total coastal traffic volume is going in/out to the port of Incheon, Busan, Pohang, Samil, Bukpyung, Mukho, Samchuk, and Jeju. 2) The main cargo items such as oil, iron material, cement, anthracite grain, fertilizer, other ore are reached to the about 70% of total amount of coastal trade. 3) ship's tonnage going in/out to the port of Bukpyiung, Busan, Pohang is increasing linearly year by year, and the amount of oil, iron material, cement, anthracite, grain, fertilizer, other ore are also increasing in linear pattern. 4) As a result of simulation, the optimum (basic) ship's tonnage.

There is a growing tendency that it gives the first primacy to inquiry learning as lesson style from lecture or simple experiment in present primary. middle and high school. But in fact. inquiry learning is difficult due to space limit, lack of laboratory, instruments and program for inquiry learning. Therefore, it is very important for science camp which stimulates much interest in science to be activated by doing of scientific activities in out-of-doors. This study is to investigate the present operational status and educational effects of science camp in which Korean and American students and teachers found. The science camps held by Seoul YMCA Chong-Ro BR. and Dongdaemun BR., Bun-Dong middle school, and Cho-Sun IL BO and Inkel corp., were analyzed. The 284 students and 12 teachers who take part in science camps in Seoul YMCA Chong-Ro BR. and Bun-Dong middle school, and 197 students who attending in 6 schools in seoul were questionaired. The 37 American students and 16 teachers in Pennsylvania, were also questionaired, Most students and teachers thought it useful regarding science-program which proceeded at science camps. And it was thought that science program had much relation to science class in school, especially science-camp made it help to arouse interests on science.

Boundary scan architecture test methodology was introduced to facilitate the testing of complex printed circuit board. The boundary scan architecture has a tremendous potential for real time monitoring of the operational status of a system without interference of normal system operation. In this paper, a new type of embedded controller for real time monitoring of the operational status of a system is proposed and designed by using boundary scan architecture. The proposed real time monitoring embedded controller consists of test access port controller and an embedded controller proposed real time monitoring embedded controller using boundary scan architecture can save the hard-wire resource and can easily interface with boundary scan architecture chip. Experimental results show that the real time monitoring using proposed embedded controller is more effective then the real time monitoring using host computer.

The purpose of this study is to propose a method for optimizing heat generation facilities to maximize revenue by investigating their operational status during times of maximum heat demand for district heating. Based on the derived result, this study also proposes a method for determining a given power plant's optimal equipment, such as combined heat and power plant(CHP), peak load boilers (PLB), heat accumulators, and so on, depending on heat demand and facility capacities. It also offers a guide for how to operate facilities more economically by considering the operational status of district heating companies.

Full embroidery industrial accidents in recent years has shown a declining trend. But disaster embroidery of domestic construction industry were more than 20,000 deaths per year is about 500 people. The government has introduced a construction site often changing the recruitment of new construction based on health and safety as an alternative to road safety education training yisuje of construction workers, daily work periods short. Certificate of Basic OSH Training in Constructions had also been evaluated as successful by reducing the accident rate problem. It is conducted in private educational institutions has occurred on the friction between workers and employers and training costs are difficult to approach workers in the education standards for such facilities due to the superintendent. Educational institutions are institutions that have been caused by excessive competition lowered levels of education. There is also a lack of evaluation that the training is limited to the basic safety knowledge. These details are brought formal safety education purposes only and is introducing the results of other self jyeotgi difficult to reap the proceeds to good effect. In this study, we propose a plan for improving operational problems and enemy status based on research data presented after the Certificate of Basic OSH Training in Construction.
