최근들어 1만TEU급 초대형 컨테이너선이 잇따라 시장에 투입되면서 선복과잉이 우려되고 있다. 과연 메가급 컨테이너선이 규모경제의 잇점을 살릴 수 있을지, 아니면 메가급 위기로 다가올지 기대와 우려가 교차되고 있다. 다음은 로이즈 쉬핑 에코노미스트(Lloyd's Shipping Economist)지 2007년 10월호에 실린 스테판 메튜(Stephen Matthews)의 "Mega-risk"를 번역한 것이다.

Environment of marine transportation market is changing rapidly. Due to globalization of world economy, marine transportation of cargos, especially trade using container boxes, is increasing dramatically. Fierce competition in the global market of container transportation forces the shipping industry to seek the economy of scale to reduce transportation cost, and drives the merge and alliance of liner shipping companies. Mega-sized container ships, having capacity over 10,000 TEU, were introduced, and appeared recently, in order to reduce the unit transportation cost. Korean shipping and shipbuilding companies are competitive, and have considerable market share in the global market. Even though both industries are inter-connected through ships and have many common interests in order to enlarge the global market share, inter-relation between two industries is surprisingly insignificant. In this paper current issues in the process of environmental change of marine cargo transportation are reviewed, and inter-relation of shipping and shipbuilding industries is discussed. Suggestions for inter-related development of Korean shipping and shipbuilding industries are given, and means for mutually beneficial collaboration are suggested.

In the country where the population concentrates in the metropolis with the narrow land, development of th ocean space is necessary. Recently, mega-float offshore structure is studied as one of the effective utilization of the ocean space. And very large floating structure are now being considered for various applications such as floating airports, offshore cities and so on. This very large structure is relatively flexible compared with real floating structures like large ships. when we estimate dynamic responses of these structures in waves, the elastic deformation is important, because vertical dimension is small compared with horizontal. And it is necessary to examine the effect of ocean wave eternal force received from the natural environment. In this study, the mat-type large floating structure is made to be analytical model. And the analysis of the dynamic response as it receives regular wave is studied. The finite element method is used in the analysis of structure part of this model. And the analysis is carried out using the boundary element method in the fluid part. In order to know the characteristics of the dynamic response of the large floating structures, effects of wavelength, bending rigidity of the structure, water depth, and wave direction on dynamic response of the floating structure are studied by use of numerical calculation.

Human-being's craving for wealthy life and a change of a culture to consume have created mega discount, stores. Therefore, a convenience for use has been required when people shop at the stores. There is tome inconvenience that customers have to find out goods and to purchase them by themselves. This is the fundamental elements for this study about a Robot design which is able to resolve that kinds of problems when shopping at mega discount stores. This study proposes guidelines for Robot design to help shopping business service. It is based on research material by analysis of consumer behavior and its questionnaire.
