Container port is one of the most vital link of the transportation chain that plays an important role in trading with other countries. Having a proper understanding of port operations could change the role of the port from a transportation node to an efficient point in a transportation chain. Development of transportation chains, logistics and progress of these networks have enhanced the sustainable condition and level of transportation. Therefore, evaluating the competitiveness of ports is obligatory for port users to make a decision in investment or exploitation. This paper introduces the use of Fuzzy C-means and TOPSIS for competitiveness comparison among a sample of container terminals in Korea and China and determine how to improve Korean port competitiveness and particularly in Busan port.

The main purpose of this study is to develop air transportation cultural index which is able to estimate the level of them. Generally Speaking, air transportation cultural, a compound word of 'air transportation' and 'culture', is a substantial entity consisting knowledge, art, morality, legality, cultivation, customs, and etc, which comes from aircraft operation sector, airport operation/management sector and user sector. They are classified in a primary scope, as aircraft operation sector relating to flight operation, airport operation/management sector and user sector. The research and analysis were taken approximately 4 months, from June 2004 to October 2004. To evaluate the index, the detailed item for three categories were chosen and quantified. The grades for each items were induced from calculation formula for air transportation cultural index by applying weight values. The final grade of Korea's air transportation cultural index recorded 63.19 points.

In Korea, although the damage from disaster (flood and storm) is increasing, the early stage warning and countermeasure are not in operation rapidly. The research areas of transportation engineering arenot diverse, so once the road is flooded and interrupted, drivers, the system operators and managers are in panic, and nearby roads are in terrible traffic congestion. In case of Korea, the research of evacuation is highly needed, because it is very necessary and easy to apply in real field. In this paper, we establish the concept of transportation disaster prevention system and suggest the directions of it. In addition, based on this research, we choose one example of disasters and establish an example of the transportation disaster prevention system. Our goal is to make steps; prevention, preparation, countermeasure and restoration in the view of minimizing on social chaos and damages emphasizing aspect of transportation countermeasure. This research will be the good precedent of approach, analysis and countermeasure when the disasters are occurred, and a basis of transportation disaster prevention system and manual in Korea.

Spent nuclear fuel, which can degrade during long-term storage, must be transported intact in normal transport conditions. In this regard, many studies, including those involving Multi-Modal Transportation Test (MMTT) campaigns, have been conducted. In order to transport the spent fuel safely, a tie-down structure for supporting and transporting a cask containing the spent fuel is essential. To ensure its structural integrity, a method for finding an optimum conceptual design for the tie-down structure is presented. An optimized transportation test model of a tie-down structure for the KORAD-21 metal cask is derived based on the proposed optimization approach, and the transportation test model is manufactured by redesigning the optimized model to enable its producibility. The topology optimization approach presented in this paper can be used to obtain optimum conceptual designs of tie-down structures developed in the future.

해운 항만산업은 수출입의 최전선이자 무한한 부가가치를 창출하는 국가적 산업이다. 최근의 세계 경제위기로 인해 항만물동량이 둔화되는 등 우리의 해운 항만산업의 어려움을 겪고 있다. 이러한 어려움은 이를 어떻게 준비하고 대응하느냐에 따라서 새로운 도약을 위한 기회가 될 수 있다. 해운 항만 업체 스스로 끊임없는 노력을 통해 경쟁력을 강화한다면 머지않아 국내에도 외국 해운 항만업체와 당당하게 경쟁할 수 있는 대표적인 업체가 생겨날 것이다. 따라서 본 연구에서는 국내 해운 항만 산업의 경제적 파급효과를 산업연관표를 이용하여 살펴보고자 한다. 산업연관표를 이용하여 해운 항만산업의 경제적 효과를 요약하면, 첫째, 2005년 생산유발계수는 항만시설이 1.958로 가장 높고 다음으로 연안 및 내륙수상운송 1.857, 하역 1.842, 기타 운수관련서비스 1.768, 보관 및 창고 1.676, 수상운수보조서비스 1.422, 외항운송이 1.283 순으로 나타났다. 둘째, 부가가치유발계수를 살펴보면, 수상운수보조서비스 0.924, 하역, 보관 및 창고 0.902, 기타 운수관련서비스 0.885, 항만시설 0.832, 연안 및 내륙수상운송 0.752, 외항운송이 0.258로 가장 낮게 나타났다. 셋째, 2005년 중 수입유발계수를 보면, 외항운송 0.742, 연안 및 내륙수상운송 0.248, 항만시설 0.168, 기타 운수관련서비스 0.115, 하역, 보관 및 창고 0.098, 수상운수보조서비스가 0.076으로 가장 낮게 나타났다. 넷째, 기타 운수 관련서비스(1.125)와 하역(0.882)의 감응도계수가 높고, 항만시설과 외항운송이 0.514로 감응도계수가 낮다. 항만시설(1.006)과 연안 및 내륙수상운송(0.954), 하역(0.946), 기타 운수관련 서비스(0.908)의 영향력계수가 높고, 반면 외항운송(0.659)의 영향력계수가 낮다.
