[OBJECTIVES] The prevalence of child obesity is steadily increasing in Korea, thus government needs to seek for effective intervention programs to counteract current epidemics. This study sought to find proven effective child obesity programs implemented in other countries in order to provide policy recommendation. We report the results of rapid review of child obesity programs which were implemented outside of Korea. [METHODS] A search of multiple databases (NICE Evidence Search, Open Grey, Grey Literature Report, National Cancer institute: research-tested intervention programs) was conducted to identify relevant research articles published after January 2010. [RESULTS] 11 studies met the inclusion criteria after systematic screening. Most of the included studies used physical activity & diet/nutrition at the same time, while school was the most common location for the intervention. 5 studies showed improvement in obesity related outcomes. Interventions contained physical activity & diet/nutrition or physical activity & psychological coaching, and intervention implemented in school, healthcare facility, summer camp, and after-school class were shown effective. [CONCLUSIONS] Considering the results of current review, multi-component intervention which includes physical activity is recommended when designing child obesity program. The location of the intervention should be school to maximize its effectiveness.

The prime objectives of this experimental study is to delineate the pulpal responses to the abutment preparations. In this study, two adult dogs of animal were prepared at the various methods of speeds such as low and high speeds of instruments. The obtained histo-pathological findings were as follows; 1) When the teeth was prepared at the low speed instruments with even water sprays, the pulpal reactions showed mild changes, but severe destructive changes of dental pulp tissues in high speed instruments 2) The vacuolization and irregular arrangements of odontoblast layer was mild affected in the` teeth of low speed instruments without water sprays and high speed instruments with even water sprays, but severely affected in the high speed instruments without water sprays. 3) The alterations of Weil's zone, pulpodentinal membrane, and predentin was present in all experimental teeth exempt for the low speed instruments with water sprays, and severe changes observed in the high speed instruments without water sprays. 4) Capillary hyperemia and infiltrations of inflammatory cells were found in all experimental teeth. 5) Hemorrhage was occurred in high speed levels of instrument with or without copious amounts of water sprays. Capillary congestions and small bleedings of odontoblast layer was occurred in the high speed levels of instruments without water sprays. 6) Mild edematous changes was present in all experimental teeth exempt for in low speed levels of heat reductions (water sprays), but highly severe changes in the teeth of high speed levels without copious amounts of waters.

While the production rate of container cargo and transportation of northeast Asia has risen faster than any other region in the world, currently many of the major ports in the northeast Asia is severe competing to take container cargoes and for survival. I supposed that the purpose of Kwangyang container port development was not only to solve many difficult problems which had faced with short of port facilities and exceed of the cargo capacity, but also to balancing national development in my country, but now Kwangyang container port is coming out various many problems such as the lack of cargo and the low utilization of shippers and fowarders even though Kwangyang port facilities have more than enough. So, now I think it is necessary to investgate and analysis stagnant causes in Kwangyang container port. 최근 동북아의 급속한 경제 성장으로 이지역이 세계의 경제 중심지로 떠오르고 있는 가운데 동북아의 주요 항만들은 물량 확보와 생존을 위해 치열한 경쟁을 하고 있다. 광양항의 개발 목적은 부산항이 안고 있는 많은 문제점들을 해결하고 국토의 균형발전을 도모하고자 하는 처지에서 시작 되었으나 광양항이 개발된 지금 시설은 오히려 남아돌고 있으나 이용율 저조와 물동량 부족으로 국가적으로 큰 과제로 떠오르고 있다. 그래서 본 연구는 광양항의 문제점 진단과 분석을 통해 해결책을 찾고자 한다.
