  • Garbage cause an environmental pollution, unsightly mess, fouls an odor, and unpleasant feeling. Various measures to solve the problems are studying. And the garbage are collected and treated by the street cleaner. Street cleaner is working for long time in the street from dawn to the night. And many kind of accidents are aroused, like traffic and crushing accident by garbage truck. This kind of accidents is increased every year. To prevent the accident, street cleaner wear a fluorescent light uniform But a count measures for the fallen accident and crushing accident from the garbage truck are insufficient. In addition, a street cleaner dose not like to wear a working uniform because of inconvenience. Therefore this study try to find a safety system of garbage truck for reducing measure of accidents of street cleaner.

  • 본 연구는 미국의 지방자치적 브로드밴드 사업동향을 통해 바람직한 u-City 사업의 추진에 필요한 접근방향을 살펴보고자 하였다. 즉, 미국의 추진사례를 바탕으로 우리나라에서 브로드밴드 사업 추진시 사업운영모델을 만들거나 국내 u-City에서의 적용 가능한 비즈니스 모델에 대한 시사점을 도출하고자 하는 것이다. 미국의 사례를 통해 국내u-City에 고려할 수 있는 부분으로서 민관합작(Pirvate-Public Partnership) 모형에대한 부분을 들 수 있다. 미국의 PPP 모형을 통해 지방정부는 고액의 유지보수 비용문제와 사고발생시 책임소재 문제를 해결할 수 있는 길을 마련하였다. 또한, 거주민에게는 경쟁을 통한 저렴한 가격으로 서비스를 제공하고, 저소득층과 불리한 여건의 거주자들에게 혜택을 제공함으로써 디지털 디바이드 문제를 줄일 수 있었다. 제도적인 면에서 한국과 미국이 브로드밴드 정책에 있어서 차이를 나타내고 있지만, 정책의 변화로 인해 국내에서도 지방자치적 브로드밴드 문제가 논의될 것에 대비하여 준비할 필요는 있을 것이다. 또한, 향후 직면할 문제점들을 사전에 예방하고 대비하는 데 도움이 되었으면 한다.

  • The objective of this study is to investigate the generation rates, composition, propertion and lower heating values of each material in the municipal solid wastes(MSW) as well as the effect of landfill leachate on the environment in Taejon. The results are as follows: 1. The annual average generation rate of MSW in Taejon is approximately 1.7kg/c.d. 2. The weight percent of combustible matters is on average 80 and the lower heating value of MSW is measured to be more than 1,700 kcal/kg after removing the briquette component. 3. It is necessary for us to take a proper management system for leachate treatment in the landfill because it has many problems in the sewage and groundwater. 4. It is recommeded that MSW be treated by multiple methods such as the sanitary landfill, resources and recovery, composting and incineration.

  • In this paper, full-scale loading tests were performed on a rectangular segmental tunnel lining, which was assembled by steel composite segments, to investigate its load-bearing structural behavior and failure mechanism. The tests were also used to confirm the composite effect by adding concrete inside to satisfy the required performance under severe loading conditions. The design of the tested rectangular segmental lining and the loading scheme are also described to better understand the bearing capacity of this composite lining structure. It is found that the structural ultimate bearing capacity is governed by the bond capacity between steel plates and the tunnel segment. The failure of the strengthened lining is the consequence of local failure of the bond at waist joints. This led to a fast decrease of the overall stiffness and eventually a loss of the structural integrity.

  • The purposes of this research were constructed the database, based on graphing the present water pollution in Han-river due to livestock wastewater(LSW). The LSW was below 1% in respect to quantity but about 7% in respect to pollutants loading in overall Han-river. The ratio of untreated LSW is 18% to 28%, which was higher compared to the municipal and industrial wastewater. In other words, LSW was about 0.05 times of municipal wastewater in respects to quantity but 2 times in respect to the ratio of untreated wastewater. So, it was necessary for treating LSW. The pollutants loading due to livestock wastewater of the South Han-river, North Han-river and main stream were 19.7%, 19.4% and 4.0%, respectively. This was about 7% in overall Han-river. We separated the Han-river into upper, mid and down stream. As a result, we found that the livestock wastewater is the main water pollution source of upper Han-river.

  • Modern society has achieved rapid growth in economy and materials whereas it caused such problems as municipal extension and high density of population, Due to rapid change of social environment, it became more complicated and multifarious than ever it before. Helping the people all kinds of routine affairs police box is giving a negative image to the citizens, for its environment doesn't have got rid of its old fashion . It's being an unharmonious factor to its surroundings, a solution is needed. So, this study is focused on recognizing the change of value system with the flow of time, planning a new image of police box for the change and in consequence recovering the trustworthy between people and the nation. For this , by grasping the characteristics of each space and through space-dividing and design corresponding to it, the plan is provided to make a pleasant interior environment of police box and to make it a symbol of local society. As a result of this study, we will have the police box not only as an office providing the locals with security and service but also as eyes of the country which watches the municipal environment.

  • Confronting with series of environmental problems. caused by urbanization and the constantly improving consciousness of the entire society towards environmental protection, it has become an inevitable trend to develop parks and green space planning that guided by the principle of 'respecting nature, preferring ecology' and integrate function, arts and culture of landscape design. Aiming at specific project, humanized design should be laid stress on. With fundamental functional construction serving as the base, the reflection of cultural content and regional landscape as the characters, using various landscape gardening elements reasonably to enrich space design as well as highlighting leisure and sport function and following the concept 'human-centered', parks and green space filled with natural vitality and cultural spirit can be constructed, people, city and the nature could develop together in harmony.

  • The objectives of this study are first, to evaluate the actual performance of the Transportation Impact Assesment System of Korea, second, to find the institutional problems of the system, and third, to seek for the best improvement of the system. Total 70 assessment reports performed in 1988 and judgements of the municipal councils of the reports were inspected. And the legal system of all levels were reviewed. According to the results, there are some needs to expand the number of cities subject to the assessment system. And the several regulations about the qualification of the agents assessing transportation impacts, the composition and operation of the municipal councils, and the timing of assessing the impacts are turned out improper. A proper alternative of amendment of the regulations are recommended. And the establishment of central council for judging assessments of hudge facilities, adoption of joint assessment of facilities bellow the standard, post occupancy assess ent, and transportation fee system were also recommended.

  • The effects of sex and age on the serum transaminase activity of 57 healthy Korean cattle (22 females and 35 males) were observed. Serum glutamic oxalacetic transaminase (SGOT) activity of the female revealed significantly higher value than that of the males. In the females, SGOT activity of 4 and 5 years group was a little decreased than 2 and 3 years, but difference was not recognized. On the other hand, SGOT activity of 4 and 5 years showed high significant increase as compared with that of 2 and 3 years in the males. The effects of sex and age on serum glutamic pyruvic transaminase (SGPT) activity and total protein levels were not found.
