This study aims to investigate how 65 years old and older men's regular exercise can affect their lymphocyte, monocyte, eosinophil, neutrophil, basophil, IgG, IgA, and IgM using meta-analysis of the related data from 8 literatures and 35 case studies which were published from 2002to 2012. The subjects with no regular exercise experience were selected for the analysis regarding the homogeneity of the background characteristics of elderly subjects. In addition, the exercise treatment was about 60 minutes per exercise three times a week for 12 to 24 weeks. Exercise intensity was a moderate aerobic exercise that the subject could endure. Regular exercise of the elderly had a mean effect size of 0.523 after the exercise. This means that immune variables before exercise increase by about 20% after regular exercise. Since regular exercise by the elderly activates the immune system, it has a beneficial effect on health.

The research of occupational injury for safety and health is a comparatively recent occurrence. As labor activities took place regarding to employee concerns in industrial uprising, human resources health was tried to enhanced as a labor safety subject. Noticing that traditional statistics approach has limitations in learning future forecasting and major factors causing occupational injuries in each industry, Korean Government initiated a quantitative systematic simulation model project to analyze how the annual injury rate has been dropped and stays in a level for recent years. From this motivation and the project, system dynamics models have been developed to explain the mechanisms for reducing annual injury rate, and the mechanisms quantitatively. The main cause effects for the reduction of annual injury rate were due to the government driven investment on safety facilities. In overall viewpoint the gain achievable from these efforts has been reached a saturated level. However, it could reduce the annual injury rate if you chose the industry and size carefully. The model for forecasting, major injury factors, safety budget and allocation are introduced and analyzed, and Analyzing occupational injury related factors can also reduce employee injury and disease related costs, including medical care, quit, and disability assistance costs.

This objective of this study is to thoroughly analyze the policies of international organizations and major advanced countries relevant to the realization of Green port To construct Green ports, there first must be competition to build such ports in sustainable, fixed quantities. Second, there is a great need for cooperation and support networks made binding by mutual agreements on ship recycling. Third, there is a need for scientific research on responses to changes in environmental regulations and on environmental issues. Today, the majority of the world's ports use gasoline or electric energy, and improving capacities for self-sufficiency through development of new and renewable energy is judged to be a pressing task. The conditions for an eco-friendly port is that it must be an important center for economic and industrial activity, and valuable as a site where people live and work, with residences and work places existing in close proximity.

In the US, there are no governing bodies within the federal executive departments dedicated to the arts and cultural affairs. Direct government subsidies for the arts are relatively small compared to other countries with a comparable economy and standard of living. Nevertheless, the US produces artworks, artists, and arts groups, leading the world's arts and culture. Incorporating the concepts of network governance and shared governance, this paper examines the dynamic roles and interrelationships among various for-profit/nonprofit arts organizations, foundations, councils, service organizations, arts advocacy groups, and professional/amateur associations from the federal to local levels that compose the ecology of American arts and culture. Through our evaluation, we conclude that the local/state/federal arts agencies and arts organizations at various levels influence each other via the principle of subsidiarity and isomorphism, creating a unique cultural policy and arts-supporting system that correspond to the political and social structure and environment of the United States.

환경용수는 수질보전, 친수환경 제공, 생물다양성 보전 등을 위하여 하천이나 농업 용수로를 흐르는 물을 말한다. 둑높이기 저수지 사업에 의하여 109개의 농업용 저수지에 증가된 저수용량만큼 2.4억 $m^3$의 환경용수가 창출되었다. 따라서 본 연구에서는 환경용수의 개념을 정립하고 둑높이기 저수지에 창출된 환경용수의 전개방향을 제시한다. 환경용수는 크게 농업적 환경용수와 비농업적 환경용수로 분류할 수 있다. 농업적 환경용수는 농업용수에 내재된 환경용수를 말하며 이를 지역용수라고도 한다. 일본에서는 여러 지역에서 비관 개기의 농업용수 수리권이 인정되어 농업용수가 마을의 생활용수, 환경용수로서 활용되고 있다. 우리나라에서는 충북 청주 무심천을 흐르는 농업용수가 여기에 해당되며, 관개기 동안 $5.0m^3/s$의 유량이 무심천 상류에서 방류되어 시내를 관통한 후 하류에서 취수되고 있다. 농업용수가 청주시내를 관통하면서 수심을 상승시켜 친수환경을 제공하고 있다. 비농업적 환경용수는 수질보전이나 생태계보전을 위한 하천유지용수나 친수환경 개선을 위한 환경개선용수가 여기에 해당된다. 일본에서는 2005년 처음으로 센다이시(仙台市)가 신규 수리권을 취득하여 비관개기에 하천수를 농업용수로를 통하여 수질개선 및 친수환경 제공의 목적으로 공급한 이후, 다수의 환경수리권 취득 사례가 보고되고 있다. 둑높이기 저수지의 농업용수는 관개기에는 관개라는 주목적 외에 내재된 환경용수의 기능을 부수하고 있다. 한편, 새로 확보된 환경용수는 갈수기나 비관개기에 하천 및 농업용수로를 통하여 공급되어야 그 기능을 발휘할 수 있다. 하천으로 방류되면 하천유지용수나 환경개선용수가 되어 하천 환경의 개선에 기여할 것이고, 용수로로 방류되면 지역용수가 되어 농촌마을의 친수 및 어메니티 향상을 위한 용수로서 활용되어 농업의 다원적(공익적) 기능 향상에 기여할 것이다. 농업의 다원적 기능은 OECD(경제협력개발기구)에서 인정된 농업에 존재하는 경제 외부효과로서 홍수조절, 지하수함양, 경관형성, 친수기능, 생태계보전 등을 말한다. 향후의 과제로서 둑높이기 저수지에 확보된 환경용수를 하천과 농업 용수로로 적절히 배분하는 기준의 설정 및 각각의 환경용수량 결정이 대두된다.

Cybersquatting is a type of conflicts between a trademark and a domain, and refers to "behaviors of registering, retaining, transferring, and using the identical or similar domain name in bad faith for the profit from the mark such as trademark". That is, it is preoccupying behavior to abuse the fact that the domain name in the Internet can be freely registered on a first come, first served basis and can't duplicate. Though this should be prohibited, given the reality that most of our daily lives are based in the Internet, this is creating many problems in IT environment beyond social structure in rule of law. Therefore, this study has the purpose that it provides cybersquatting-related information and suggests legislative implications hereafter through the analysis of cybersquatting-related precedent from the Supreme Court.
