Since the solar radiation is the main input for sizing any solar system, it will be necessary to understand and evaluate the insolation data. The horizontal global insolation data have been measured since May, 1982 and direct normal solar insolation data since December 1990 at 16 different sites all over the country and considerable effort has been made for constructing a standard value from measured data at each station. In the results, the average global total solar radiation of the nation is $3,055kcal/m^2.day(12.79MJ/m^2.day)$ and the average clear day direct normal solar beam radiation was $4,600kcal/m^2.day(19.26MJ/m^2.day)$, which indicates possible solar energy application of medium and high temperature technologies with high concentration.

Objective : Bambusae Caulis in Liquamen has been used by East Asian doctors who approved efficient clinical effects of it since the early stage of medical history. It is commonly used for lifestyle related diseases including stroke in recent days thanks to the increasing number of manufacturers. However, products from pharmaceutical companies as well as food companies are not classified as Bambusae Caulis in Liquamen but Bamboo vinegar. This study aims to discern disparate manufacturing process. Methods : In this study, original texts were searched to corroborate the correct method to produce Bambusae Caulis in Liquamen. It is essential to inspect the original texts thoroughly in the course of modernizing traditional knowledge. Result : Discrimination between the two substances starts from manufacturing process; Bambusae Caulis in Liquamen is made under the temperature of less then $170^{\circ}C$, containing mild fragrance and sweet taste, and the Bamboo vinegar over $170^{\circ}C$ upto $400^{\circ}C$, carrying strong smoky scent and acidness. Although some researches show conforming clinical actions of both products, still there is a possibility that closer clinical study would reveal their discrepancy. Conclusion : Current use of Bambusae vinegar needs speculation. Authenticity in proper manufacturing process can be attained through passed-on medical texts.

본 연구에서는 김수철 사건이후 각계각층의 전문가들의 노력 및 정부의 재발 방지를 다짐하며 학교 안전강화 대책을 연이어 내 놓았지만 외부로부터의 위험은 감소하지 않고 있는 실정이다. 외부로부터의 위험을 예방하고 최소한으로 피해를 줄이기 위해서는 가장 기초적인 안전대책의 강구와 인식의 변화를 통한 안전대책의 재평가와 개선방안이 시급하다. 따라서 학교 안전대책 방안을 위하여 현재 실시하고 있는 배움터지킴이제도와 학교 보안관제도 그리고 더 나아가 경비업체와의 협력과 인력의 확충을 통하여 학교 안전을 도모하고 외부인이 자유롭게 출입을 하지 못하도록 CPTED의 기법을 활용하고 학교 외곽에 외부인이 출입이 자유롭지 못하도록 담장을 설치하고 실제적인 감시와 통한 범죄예방과 대처를 위한 CCTV의 확충과 장치를 보완을 통하여 각각의 안전대책 방안을 효과적이고 통합적으로 운용할 수 있도록 한다.

Since the direct normal insolation is a main factor for designing any focusing solar system, it is necessary to evaluate its characteristics all over the country. We have begun collecting direct normal insolation data since December 1990 at 16 different locations and considerable effort has been made for constructing a standard value from measured data at each station. KIER(Korea Institute of Energy Research)'s new data will be extensively used by concentrating system users or designers as well as by research institutes. From the results, we can conclude that 1) Yearly mean $4,576kcal/m^2.day$ of the direct normal insolation was evaluated for clear day all over 16 areas in Korea. 2) Clear day's direct normal insolation of spring and summer were $4,710kcal/m^2.day$ and $4,960kcal/m^2.day$, and for fall and winter their values were $4,484kcal/m^2.day$ and $4,151kcal/m^2.day$ respectively. So, spring and summer were higher, and fall and winter were lower than the yearly mean value.

The Fuel cell Rubber tired Train (FRT), which is now getting the attention as the next generation vehicle with its environment-friendliness, is the transportation for smooth connections of city traffic. It is the revival of the surface-car system with its revaluation of the function and technological development. Accordingly, fixed time operation and high speed driving became possible. FRT is operated together with other vehicles on the regular drive way. While this vehicle can solve the problem of traffic congestion in the urban area, it also can be cost-effective when it is compared to the cost of subway construction. It is also designed to minimize the underground or elevated traffic lane, to introduce the new construction technology, to reduce a term of works, and to cut down the operation cost by unmanned automatic driving system. Furthermore, it is considered as the alternative measure of other transportation due to its potential for the ecological way of speed improvement and the accessability to the disabled, elderly and children by developing the vehicle with folding steps or by building the high boarding platforms. In this research, I concentrated on the user oriented interior design of the FRT to make it passenger-friendly and safe in order to maximize the utilization of the vehicle so that all users including wheelchaired, user with baby carriage, elderly and children can conveniently use this vehicle.

The Busan shoe industry has been the accelerating overseas transfer of production facilities due to loss of competitiveness in the wake of drastic revaluation of the won, an increase in personnel expenses and the rise of backup developing countries since the late 1980s. On account of changes in the general system of supply and demand caused by a decrease in exports and production, the Industrial structure has been subjected to a transition from export to domestic demand. As a result, the Busan shoe industry, which used to rank second in the world in terms of its shoe export and to account for 16.5% in terms of its market share, started to be regarded as a fast-fading industry. As a domestic companies have a tendency to almost all the tasks on bloc, it is true that their competitiveness is on the rapid decline for they prefer self-reliance on the premise that all the production should be dealt with for themselves. It is outsourcing that is taken into account as a strategic vehicle for converting such self-reliance into the system of low expenditure and high efficiency.

Since the atmospheric clearness index is main factor for evaluating atmosphere environment, it is necessary to estimate its characteristics all over the major cities in Korea Peninsula. We have begun collecting clearness index data since 1982 at 16 different cities in South Korea and estimated using empirical forecasting models at 21 different stations over the North Korea from 1982 to 2008. This considerable effort has been made for constructing a standard value from measured data at each city. The new clearness data for global-dimming analysis will be extensively used by evaluating atmospheric environment as well as by solar PV application system designer or users. From the results, we can conclude that. 1) Yearly mean 63.5 % of the atmospheric clearness index was evaluated for clear day all over the 37 cities in Korea Peninsula, 2) Clear day's atmospheric clearness index of spring and summer were 64.6% and 64.8%, and for fall and winter their values were 63.3% and 61.3% respectively in Korea Peninsula.
