This study was conducted to do a comparative analysis of hunting system in 16 OECD(Organization for Economic Co-operation and Development) countries. Hunting is one of the most advanced types for developing natural resources, esp. wildlife, which is one of major products from forest. There are two types of hunting system ; Revier and/or License System, around most countries which have traditional advanced hunting and higher hunter population. Licence system, which is chosen in Korea, is less efficient ways of hunting for maximizing economical value and wildlife management than Revier system does. Adopting better system for much more efficient economical condition from hunting in Korea in a future is a ultimate goal in this study. The first step for the goal is an analysis of these two system among 16 DECD countries ; United State, Japan, Germany, France, etc. Comparative researches in hunting regulations such as number of hunters, hunter ratio to population, hunting bags, game species, seasons, ammunition and hunting permit are a next step for adopting developed hunting system in Korea. Korea has a smallest hunter ratio to population (1/2,463) among 16 DECD centuries and economical value lead by hunting is estimated still very low. Revier system is a popular one in most DECD countries except United State, Japan, etc, which is useful for wildlife management and maximizing economical value of hunting. And usually rifles are permitted for big game hunting. Hunting examination and/or insurance are compulsory for achieving hunting permit. Depend on game species, yearly hunting bag and season are constructed in most DECD countries.

The water quality of Anyang stream, the first tributary of Han River, was investigated from 2006 to 2010. The concentrations of nutrients and organic contents such as ammonia, nitrite, nitrate, phosphate, and chemical oxygen demand in water were measured by grab sampling analysis. Water samples were collected at the marked point for five years. According to pollutant levels, Anyang stream was divided into six zones. Spatial changes of annual water pollution were demonstrated using zone identification and strip analysis technology.

이 연구에서는 LNG 저장탱크 외조 벽체의 수직 텐던 적용을 위한 2360MPa 고강도 강연선용 수직고정 정착장치의 성능평가를 실시하였다. 콘크리트와 강연선 간의 부착특성과 일반 정착장치의 하중전달 메카니즘에 대한 검토가 이루어졌으며, 이를 기반으로 실 구조물에 적합한 설계제원을 결정하였다. EAD 160004-00-0301의 ‘mechanical anchorage’와 ‘bond anchorage’ 기준을 참고하여 시험체 제작기준을 정립하고 시험체에 대한 하중전달시험을 실시하였다. 시험결과 개발된 수직 고정 정착장치가 EAD 160004-00-0301 수준 이상의 하중전달성능을 확보하고 있음을 확인하였다. In this study, embedded post-tensioning anchorage device for high strength strands was tested for evaluation of its load transfer capacity from strand to concrete block. The bonding characteristics between concrete and strands was investigated. Referring to ‘load transfer test – mechanical anchorage’ and ‘load transfer test – bond anchorage’ of EAD 160004-00-0301, specimens were designed. They were tested up to 95% AUTS. From the test results, its feasibility for use in LNG storage tank was verified.
