As a part of environmental pollution prevention and resources recycling, the regeneration of waste tire has been largely contributed to national industry. But, the worker has been evaded this regeneration process by reason of the best mischievous process condition among 3D industries. So, the first, the process condition of regenerating waste tire was analyzed. The second, the equipment or system was developed for the improvement of working strength and environment. The last, researchers intend to solve these problems

The article provides an assessment of the dynamics of cancer incidence and mortality in the territory of Aktobe city for the period 2000-2010. The most common cancers were found in the lungs, stomach, esophagus and breast throughout the period, with slight increase in colon cancer and decrease in esophageal cancer being apparent. In an attempt to cast light on effects of environmental pollution, the authors also compared data on total emissions of chemicals into the air. While preliminary, the findings provide a basic picture of cancer burden in this industrialised city in Kazakhstan which should be followed up by more comprehensive monitoring.

In the era of climate change, the feasibility of a 'multi-functional storage facility' was evaluated in terms of various key performance indices such as flooding prevention effects, urban pollution reduction effects, and rainwater harvesting effects. As a result, the Korea Ministry of Environment introduced a new concept of 'multi-functional storage facility' for sewer flooding prevention and urban non-point pollution reduction. Prior to introducing these infrastructure (a large underground storage facility), the more details were needed to be examined carefully in all of technical aspects of construction and management. It was also well known that the validity of installation of 'multi-functional storage facility' was sometimes weakened because of a low B/C ratio.

We performed the two analyses of variance to determine the total quality management practices in the environmental pollution prevention industry by classifying the companies based on the size (large or medium/small) and on the type (manufacturing or service). A few previous studies reveal that in Korea the large companies are not the same as the medium/small companies in the TQM practices while the practices are not alterated by the type of companies whether manufacturing or service. But in the United States the TQM practices are not affected by the size of the company. Su, pp.rting the previous studies on the Korean industry our studies show that the TQM practices are significantly influenced by the company size, but not by the type of the company. Taking the results of our studies into consideration we would also like to propose a revision of examination criteria for National Quality Management Award with special emphasis given to medium/small companies.

본 논문에서는 태양광 전지판을 장착한 LED 가로등을 설계 제작하였다. 제작비용을 고려하여 간단한 구조에서 태양광 전지판에 많은 양의 태양광을 받도록 하고, 태양이 없어 발전을 하지 않을 때는 태양광 전지판에 오염 물질이 적게 부착되게 하며 또 태양광 전지판에 붙은 이물질, 오염 물질을 쉽게 제거 작업을 하게 하기 위하여 태양광 전지판을 접을 수 있도록 구성하였다. 또한 LED 인버터를 사용하지 아니하고 직류를 그대로 사용하게 하므로 전기 변환에 따른 에너지 손실을 방지할 수 있고, 이에따라 시스템의 효율을 기할 수 있었다. 본 연구를 통해 LED 등 설계 및 제작 기술, 인버터 변환 없는 직류 사용 효율 증대 기술, 원격 및 수동 조작 Controller 설계 및 제작 기술, 접이식 Sollar Cell 기구물 개발 기술을 확보하고 향후 태양광 전지판 가로등과 관련된 다양한 연구를 할 수 있는 기반을 마련하였다.

In China, environmental noise policies are composed of correlated laws adopted by the Standing Committee of the National People's Congress and promulgated by the President of the country, regulations promulgated by the State Council and/or local government, standards issued by the Standardization Administration Committee (SAC) under the State Council. The laws mainly include the 'Environmental Protection Law' and the 'Law on Prevention and Control of Pollution From Environmental Noise' Regulations are often applied to a special noise pollution phenomenon of wide influence. They are generally only effective in a given area and/or a specific period. Tens of correlated standards specify the noise level limits of different functional zones of land use and of different equipment, machines, devices, appliances etc., and the measurement methods. In this presentation, a brief introduction to these policies and their operations is given and discussed. The conclusion is that the policies supply an effective legislative basis for environmental noise prevention and control in China, but still a lot of work should be conducted and completed to strive for a quiet society.

After the Sea Prince oil spill accident in 1995, the korean government has taken a measure to establish an emergency response system and equip clean-up capacity against large spill, major contents of which are as follows: First, Korea Marine Pollution Response Corporation has been established as a non-government organization for recovery of spilled oil in order to improve private response capabilities. Second, clean-up equipments, such as large clean-up vessels and oil fences for the open sea operation has been expanded. Third, a national contingency plan on the large spill accidents has been established compliance with the provisions of Article 6 of the OPRC 1990. However, there exist some problems in the national response system, such as clearly roles definition between government and private agencies; propel amendment of the Marine Pollution Prevention Act to incorporate major contents of the OPRC 1990; and training and exercises of clean-up personnel. With the above problems in mind, this paper reviews the current issues on the national oil pollution response system and recommends policy-making to tackle to those problems.

Commercially available fuel oil for power plant contains relatively much sulphur, which means accordingly high content sulphur deoxide in exhaust gas. Sulphur deoxide has been identified as the worst-pollutant caused by thermal power generation. This paper primarily deals with the stack gas diffusion effects of various parameters, namely vertical stability, wind velocity, exhaust gas velocity, stack height, etc., on the ground concentration. thereof the relation between stack height and maximum plant capacity is analyzed from the standpoint of air pollution prevention. The limit capacity is calculated by means of mean concentration introducing Mead and Lowry coefficient respectively.
