PURPOSES : The aim of this study is to analyze economic effect of bike-sharing after its introduction in Korea. METHODS : This study reviews current bike-sharing situations in Korea and other nations. We conduct surveys on bike-sharing system's bike usage patterns and economic benefits in Changwon and Goyang cities where public bikes are the most popular in the nation. Economic benefits are itemized after reviewing relevant previous studies. Then, the survey is implemented using the Contingent Valuation Method (CVM). Then estimated benefit is compared to the cost which is necessary for bike-sharing introduction and operation. RESULTS : Using the average WTP per household, the total economic benefit of bike-sharing is estimated as much as 1.75 billion KRW to 3.75 billion KRW in Goyang and Changwon city. Using estimated benefit, economic effect of bike-sharing are calculated as 0.69 and 1.00, respectively. CONCLUSIONS : The result of this study shows bike-sharing could be useful economic policy in Korea. However, economic effect of bike-sharing differs by city.

Pintle injector is the most suitable injector for thrust control because it can control the area of propellant injection. Accordingly, the combustion test of multiple hole pintle injector and continuous type pintle injector was carried out in this paper using liquid oxygen and gas methane. The combustion performance of the two pintles was verified with the characteristic speed efficiency, and the experimental results were compared according to the O/F and combustion chamber pressure and under similar conditions. The efficiency of the multi hole pintle was generally somewhat higher than continuous pintle when pintle opening distance(the area of dispensing oxidizer) was in a 100% thrust condition.

최근 3D콘텐츠에 대한 주목, N-Screen 환경조성, 종편사업자등장 등의 환경 변화를 배경으로 방송영상콘텐츠산업이 급성장 하고 있다. 그리고 그 중심에 스마트 콘텐츠가 있고, 스마트 콘텐츠를 제작하는 과정에 중요한 역할을 하는 CG, VFX 로 대표되는 특수 영상분야가 주목받고 있다. 고양시는 이러한 시대변화를 앞서 읽고 CG/3D 기업육성, 아쿠아스튜디오 조성 등 타지자체와 차별화된 정책을 추진하여 관련 분야에 경쟁력을 확보하여 지역경제 활성화를 위한 블루오션을 개척하였다. 이에 본 논문은 고양아쿠아스튜디오의 현황 및 향후 가능성을 보고자한다. 고양아쿠아스튜디오가 단순한 개별시설로서 활용되는 것이 아니라 고양시의 방송영상 로케이션, 후반작업 등 문화산업의 가치사슬인 기획-제작-후반작업-배급 등과 연계되어 상승작용 하므로 지역경제 활성화 기여할 수 있는 가능성에 대해 고민하였다. 고양아쿠아스튜디오의 가능성으로 문화산업기반 조성 확대, 폐정수장을 문화산업을 테마로 재활용하는 도시재생의 시범사례 그리고 기업의 방송영상제작환경 제고와 고양아쿠아스튜디오의 테마(Theme)공원화 등을 제시한다.

In this study, it analyses the problems of the Fire Compartment in Goyang Bus Terminal. Based on analysed data, it is confirmed the necessity of the Smoke Compartment installation for Protecting the Smoke Spread in Large-Scale Buildings using of FDS(Fire Dynamics Simulation). In addition it suggest that the necessity of Smoke Compartment application method and Development of Design Guideline.
