Companies are facing challenges to have high competitiveness because of continuous oil price rising and CO2 emissions regulations. Thus, companies are trying hard to construct effective logistics and operation system to achieve high customer service quality and saving cost. Also the ec-friendly idustrial complex is needed. Busan is in process to construct GILC(Global Industry Logistics City) in west Busan province to achieve high competitiveness and support lack of industrial complex. To construct this kind of logistics industrial complex, it needs logistics system through proper policy and freight transportation co-operation. Especially, efficient management through logistics hierarchy construction in industrial complex is very important for low cost and eco-friendly point of view. Therefore, this paper aims to analyze logistics system and suggest operation model to present logistics complex construction base data.

The purpose of this paper is to estimate economic benefits for the investment of railway transshipment system with non-powered turntable. The freight transport by railway can have decided advantages over trucks in terms of energy efficiency, emissions and cost for certain freight movements, just as transportation in the metropolitan region can have great advantages over driving truck. But the freight transport by truck should gain significant mobility benefits from a freight railway system. Thus, the railway transshipment system with non-powered turntable which is coupled railway transport advantages with load transport advantages has been developed and used in the european countries. This research has conducted the empirical analysis, by calculating the investment of railway transshipment system with non-powered turntable. The key factor for the economic benefits for the non-powered turntable is the utilizing throughputs. This demand is influenced by the throughput in the railway transshipment system. The main results of this paper are as follows: railway transshipment system with non-powered turntable does not have economic benefit for investment. We recommend that the plan for investment has to be considered the modification.

철도는 대량수송 및 정시제 운행이라는 중요한 역할을 하면서도 다른 한편으로는 철도연변에 거주하고 있는 사람들에게 상당한 소음공해를 미쳐 정온한 생활환경을 누릴 권리를 침해하고 있음에도 불구하고 철도소음을 관리하는 기준이나 대책등이 아직 미미한 실정이다. 향후 5년 내에는 고속철도의 등장도 확실하지만 기존 재래식 철도에 대한 소음 실태 자료마저 충분치 않아 철도연변의 소음진동 문제를 해결하기 위한 기본적 수단인 소음 기준 제시를 위해서는 폭넓은 기초 자료확보와 새로운 관련연구가 요청되었다. 이러한 필요성에 따라 전기기관차를 중심으로 영동선, 중앙선, 태백선, 경인선, 경원선 및 대도시 도심지를 관통하는 호남선 및 경부선 중에서 측정환경이 양호한 22개 지역을 선정하여 기존 철도의 구간별 30분, 1시간, 2시간, 3시간 등가소음도를 측정하였고 선로의 조건, 열차의 종류 및 속도, 거리권별 등에 따른 개별열차 통행시의 소음특성을 조사하여 철도소음의 기준 설정과 방지대책 강구시에 활용할 수 있도록 하며, 열차 통행속도로부터 최고소음도를 추정하여 주변지역의 등가소음도를 산정할 수 잇는 예측식을 도출하여 측정방법 개정에 활용하고, 그리고 선로변에 위치한 공동주택을 대상으로 층별 철도소음 노출도와 열차통과시의 공동주택 실내.외의 소음도를 비교조사하여 벽체 차음 효과를 조사하였고 철도소음에 대한 주민반응 조사를 하였다.

Current competition among companies than regional, the time constraints, it is globalization, Tilt the efforts of many to be operated by building the efficient distribution system to reduce logistics costs and improve customer service it is reality's there. Therefore, the need for industrial complexes environmentally friendly can be cost competitive companies perform cavitation region's increased. To build the distribution center these logistics system through a joint of freight and appropriate policy is required. In particular, efficient operation through the system construction of industrial complexes in the logistics system is very important in terms of friendly low-cost urban logistics, the environment. Since the traffic volume which is Jipufa and utilization of network is transported by a more appropriate technicians and means suitable operating model can efficiency is improved. However, despite these advantages, research network design has not been actively conducted due to the complexity of the problem. Therefore, in this study, by analyzing the logistics system, and presents the operating model through a simulation and basic settings for the model of the logistics complex based on the analysis result, the construction of infrastructure of logistics industry complex it is intended to present the article.

Natural gas hydrates typically contain 85 wt.% water and 15 wt.% natural gas, and commonly belongs to cubic structure I and II. When referred to standard conditions, 1㎥ solid hydrates contain up to 172N㎥ of methane gas, depending on the pressure and temperature of production. Such large volumes make natural gas hydrates can be used to store and transport natural gas. So, the tests were performed on the formation of natural gas hydrate is governed by the pressure, temperature, gas composition etc. The results show that the formation pressure of structure II is lower about 65% and the solubility is higher about 3 times than that of structure I.

전 세계적으로 수소연료전지에 대한 관심이 집중되고 있다. 이미 미국, 일본, 캐나다 등 선진국에서는 수송용, 가정 상업용, 휴대용 등 다양한 용도의 연료전지 기술개발 및 보급에 나서고 있다. 우리나라는 아직 연구개발 및 실증단계에 머물러 있다. 정부는 2012년까지 연료전지 자동차 3,200대, 가정용 1만기, 상업용 2,000기, 분산전원용 300기를 보급하다는 목표로 연료전지 보급을 추진하고 있다. 연료전지 전문가들은 이러한 보급을 통해 급속한 가격인하가 예상돼 경쟁력 있는 기술과 상품으로 거듭날 것으로 전망하고 있다. 특히 동양건설산업이 세계 최초로 경기도 남양주에 연료전지 공동주택을 2010년 준공할 예정이어서 건설업계의 연료전지 주택 보급 활성화의 계기가 될 것으로 예상된다. 연료전지 자동차의 경우 수소충전소가 필요하다. 이러한 점에서 중장기적으로 수소충전소 설비 건설 분야가 설비건설업계의 새로운 시장이 될 가능성을 기대해볼 수 있다. 이번 호에서는 연료전지 기술 및 동향, 시공사례를 살펴본다.

Companies are reluctant to disclose information because of trade secret and corporate identity For the same reasons, logistics companies do not want to operate in the form of a community In urban areas, the loading of vehicles is 100% as the quantity of goods transported is too much. In mountain areas, however, the load condition of the vehicle is not 100% because of the low quantity of goods transported Therefore, the transportation costs will increase as the cost of transport increase, the competitiveness of firms will also decline In this paper, we studied a simulation to measure driving time and volume of cargo according to the change of the quantity of goods transported in the mountain area According to the research results, we got a conclusion that the proposed method makes the operation time be less and the volume of cargo increase compared with the existing operation method.
