This study is to investigate the removal efficiency of Cr^(+6) from waste water by using the coprecipitation phenomena. Experiments were performed mainly by using the jar tester at pH range of 8 to 11. Cr^(+6) concentration was 1㎎/ℓ with different concentrations of ammonium ferrous sulfate, which were 5 to 100㎎/ℓ as Fe^(+2). Following conclusion were obtained from the results of this study. Removal efficiency was highly improved compared to the conventional hydroxide precipitation treatment. The optimum conditions for Cr^(+6) removal is at pH range of 9 to 10 and over the ratio(㎎/ℓ Fe^(+2)㎎/ℓCr^(+6)) of 5. The added So₄^(-2) at pH range of 5 to 6 improved on the coprecipitation of Cr^(+6). The added Ca^(+2) at pH range 10 to 11 improved on the coprecipitation of Cr^(+6).

The green development policy advocated by the Lee Myung-bak administration in 2008 has been intended to take considerations on both economic growth and environmental issues. The president can be said to exert a balanced, forward-looking leadership by pushing ahead with the policy. The purpose of this study was to examine how to ensure the growth of sports and the settlement of environmental problems at the same time in line with the green development policy. Relevant theories were analyzed to explore the logical oughtness of green development and strategies for that policy, and then problems with sport environments and relevant disputes were discussed. After discussions on sports and environmental issues were checked, what environmental problems took place in association with the construction and management of large sport facilities such as golf course and ski resort were pointed out, and both of sports and environmental problems were discussed from administrative, legal and ethical perspectives. As environmental problems related to sport activities have a huge impact on hosting international sport events, the urgent necessity of countermeasures for that phenomenon was stressed, and several alternatives were suggested to strike a balance between the growth of sports and the settlement of environmental problems in today's green development era, which involved a spread of environmental awareness equal to that of advanced countries, a procurement of environment-friendly sport spaces, reinforced evaluation of the impact of the environment, mediation of people's basic rights, and a more down-to-earth definition of the environment. 2008년 이명박 정부에 의해 제창된 녹색성장 정책은 경제성장과 환경문제를 동시에 고려하자는 주장으로서 이는 균형감각이 갖춰진 미래지향적 리더십으로 평가할 수 있다. 이에 이 연구는 녹색성장 정책기조의 맥락에서 스포츠의 성장과 환경문제가 동시에 고려될 수 있는 방안을 모색하고자 하는데 목적이 있다. 즉 녹색성장의 추진방향과 과정에 대한 논리적 당위성과 실천전략을 포괄적으로 다룰 수 있는 이론적 체계의 구축을 도모하고 이를 토대로 스포츠 환경의 문제와 쟁점들을 논의하였다. 연구내용의 구성은 스포츠와 환경문제의 논의를 기반으로 하여 골프장과 스키장 등과 같은 대규모 스포츠 시설의 건립과 운영상에서 대두되는 환경문제를 지적하는 한편으로, 스포츠와 환경문제에서 실질적 논쟁의 대상인 요소들을 행정적, 법적, 윤리적 쟁점으로 부각시키고 이를 고찰하였다. 또한 최근 스포츠 활동과 관련한 환경문제가 국제적 스포츠이벤트 유치에 필수적인 요소로 부각되고 있어 이에 대한 대비책 마련이 시급함을 강조하고, 녹색성장 시대에 발맞추어 스포츠의 성장과 환경문제에 대한 균형감각을 이루기 위한 대안으로서 국제적 수준의 환경의식 제고, 친환경 스포츠공간의 확보, 환경영향평가의 강화, 국민 기본권 간의 중재와 타협, 실천적 환경정의의 정초 등을 설정하였다.

The purpose of this study is to explore and discuss some of the environmental management implications, problems and strategies in corporate operation as it adopts new paradigm to survive in changing society. The background and current situation are analysed and future recommendations made. The paper attempted to discuss factors contributing to the circumstances and endeavor to imply possible solutions. In conclusion, the widespread awareness of global environmental problems has put pressure on companies to better manage their environmental responsibilities. Therefore, the companies facing an environmental restraints and pressure of environmental organization needs to adopt environmental management as new paradigm such as environmental management system, environmental auditing and environmental performance evaluation. However, most of domestic companies tend to neglect an investment related to environmental management and have little understanding. The involved companies in environmental management are small and in short of high technology. To overcome these obstacles, some suggestions are as follows: First, companies should set up an effective environment strategy in order to meet the objective of environmental management. Second, it need to establish a detail and practical programs to meet the demands of reality. Third, it is necessary a change of recognition and creating value of environmental management, setting up effective strategy of environmental management and providing its information.

The purpose of this paper is made an experiment of the adsorption rate of NH₄-N and PO₄-P in soil samples. The results obtained were as follows. 1. Influence of particle distribution on the adsorption rate of NH₄-N and PO₄-P is expressed opposite tendency between sand percentage and silt plus clay percentage. adsorption rate of NH₄-N and PO₄-P is not increase in proportion to clay percentage. 2. Adsorption rate of PO₄-P as compared with NH₄-N in soil samples shows a slightly higher rate. 3. Adsorption rate of NH₄-N is affected quite sensitively in order of K^(+)>Ca^(2+)≒Mg^(2+)>Na^(+). 4. Cl ion the adsorption rate of PO₄-P is not affected very much.

The purpose of this paper was to develop the activity of traditional festival for the senior citizens' health in Daegu city. Recently, the positive factors for a local festival has not been revealed because of the cultural extinction, and administrational expedient. These phases distorted the succession of traditional festival and their life. Furthermore, These phases also caused that these senior citizens lost their traditional origin. Daegu city has been regarded one of culturally important city in South Korea. Therefore, this study attempted to practice a political task that people respect and care old people for their health, entertainment and life in Daegu city. Finally, developing their health through providing traditional festival could be able to establish a relationship between senior people and society.

Removal of Phosphorus compounds from food waste water is an important operation, because these compounds play a critical role in lake eutrophication. Emphasis has been given to phosphorus removal for one reason : phosphorus is the mist critical nutrient. The purpose of this paper is made an experiment on the phosphorus removal of food waste water. The results are summarized as follows : 1. The phosphorus removal rate is above 90% in case of Fe^(+3)/PO₄^(-3)-P mole>1.7 and Al^(+3)/PO₄^(-3)-P mole>1.5 on the high phosphorus concentration in food waste water. 2. C.O.D removal rate shows above 90% in case of increasing Al^(+3) dosages. Influence of increasing Fe^(+3) dosages on the C.O.D removal rate is expressed opposite tendency to Al^(+3) dosages, C.O.D removal rate is on the decrease. 3. Suspended Solids in the treated effluent influences phosphorus removal rate and C.O.D removal rate, decreased each removal rate.
