The logistics industry is growing rapidly with China's economic development in recent years. Particularly, the intermodal freight system is becoming the main issue to reduce the logistic costs under the situation that the quantity of cargo transported between Korea and China is continuously increasing. Shift from road transportation to eco-friendly modes such as rail and coastwise shipping is also increasing. The present study suggests technical aspects related to the implementation of intermodal transport system centered on train ferries between two countries with already employed Chinese infrastructure into consideration. Technical assessment of intermodal train ferry system entails not only the vessels but supporting facilities and technologies as well. Port and rail facilities and operating skills for efficient modal shifting, and their standardization is indispensible to the realization of an intermodal train ferry system between the two countries.

A strategic planning to attain a Marine Logistic Transportation Center on the Far-Eastern Pacific is investigated and is being reviewed at the NTRM Vision IV. Utilizing high speed super-sized container carriers, 15,000TEU and 35knots, between the two hub-ports, a western coast city of the United States and Kwangyang/Busan of South Korea, are motivated by now highly successful shipbuilding and maritime industries. SMART, 330MW thermal power plant under planning, will greatly expedite the transfer of cargoes across the Pacific. A sizable effort is required to achieve the goal, but the reward will also be very great, technically, economically, socially and geo-politically.

21세기에 들어서서 새로운 신에너지원으로 각광을 받는 연료전지는 지구온난화의 영향으로 청정에너지를 더욱더 필요로 하는 에너지를 부상시켰다. 2000년을 기점으로 다양한 연료전지기술들이 다양한 응용분야에 기술개발이 이루어지고 있으며 2004년에는 11,000기 이상의 연료전지제품이 출시되는 등 급속한 발전을 거두고 있다. 특히 연료전지 제품의 시장화에 앞장서고 있는 수송용 연료전지는 차세대자동차의 대체 상품으로 지목받으면서 메이커 중심으로 상용화에 노력을 배가하고 있는 실정이다. 본 논문에서는 연료전지의 전반적인 시장구조를 살펴보고, 특히 수송용 연료전지의 시장과 산업에 관하여 분석하고 틈새시장 진입을 위한 전략을 제시하였다.

This study investigated to understand the trend of international commercializing technologies and industrial status of the transportation biofuel based on lignocellulosic biomass. Two major commercializing technologies for the lignocellulosic biofuel are biochemical conversion technology and thermochemical conversion technology. It was reported that a total of 93 industrial companies were using lignocellulosic biomass of all facilities related to advanced biofuel. On the basis of commercial type, the biochemical conversion technology was identified to be the major technology in the lignocellulosic biofuel industries, showing 84% of all. Also the main products of commercial type industrial companies are bioethanol (1,155,000 tons/yr) and bio-oil (120,000 tons/yr), which are in a remarkably inadequate amount to substitute for the transportation biofuel worldwide. It was suggested that the transportation biofuel market was currently in need of further development in both technology and scale, and was in high demands of technological development and commercializing exertion.

A third of primary energy is lost as a waste heat. To improve this inefficient use of energy, systems using chemical reaction have been suggested and studied. In this study, methanol decomposition/synthesis reaction as a chemical reaction was selected for long time heat storage and long distance heat transport system because of safe, cheap and gaseous product. The purpose of this study is to find the optimal conditions in the methanol decomposition and synthesis reactions for long distance heat transport. Several parameters such as reaction temperature, pressure, $H_2$/CO ratio, space velocity, catalyst particle size were tested to find the effects on the reaction rates for the methanol synthesis. And the reaction temperature, space velocity, catalyst particle size were tested to find the effects on the production concentration for the methanol decomposition.

It is connected with various gauges existing in Euro-Asian continents. Such differences impedes the operation seriously as on the contact of railway tracks of different gauge the cargo must be either transshipped or the running assemblies of rail vehicles must be exchanged. Those operations are costly, time-consuming and require extended infrastructure together with very expensive storage and transshipment facilities at border-crossing point. Moreover, those operations extend transportation time considerably. Therefore, effectiveness of railway transportation systems significantly depends on track gauge change 1435/1520mm, which connects with complicated handling-shifting operations. The paper concerns assessment of effectiveness in strategical rail systems with gauge changing. The paper presents short description of transport system with gauge changing and initial assessment of shifting technologies. Method of system assessment comparison based on Life Cycle Cost model is described here as well.

기존 골판지는 제품보호나 수송을 목적으로 사용하나, 소비자의 소비 패턴의 변화 등 시장동향에 따라 포장재의 고급화, 그래픽과 인쇄성의 강조 및 제품수송비용을 절감시킬 수 있는 포장재로서 마이크로플루트 골판지 포장재가 대두되고 있다. 이에 한국골판지포장공업협동조합은 3년여에 걸쳐 조합원사 및 서울대학교와 연계하여 연구과제를 수행하였으며, 그 연구 결과물을 알아보고자 한다.
