Based on the fact that Qingdao port, Tianjin port and Dalian port of the economic circle around Bohai have been the three islands of stability through long-term competition, this paper conducts a system study on the competitive powers of the three ports through AHP model on the analysis of current status of the three ports, and probes deeply into the outer factors and the inner factors affecting on the competitive advantage, and points out the existing problems in competition. We think that the three ports must compete orderly and collaborate closely, and give the forms and approaches developing strategy collaboration in order to obtain an advantageous position in Northeast Asia and improve the international competitive power.

A 3-year-old girl with a primitive neuroectodermal tumor (PNET) and a 6-yearold girl with acute lymphoid leukemia were referred to us because of problems with their implantable central venous ports (Port-A-Cath$^{(R)}$). On physical examination, the ports were upside-down, so a needle could notbe inserted through the membrane of the port. Right lateral side view of the chest radiogram confirmed port inversion in both cases. At operation, the ports were inverted and the transfixing sutures were totally absorbed. The ports were rotated 180 degrees and anchoring sutures placed.

Many countries in the North East Asia are competing with each other in order to become a centre of international logistics activities. The competition to become a hub port in Far East region is now fierce. The anticipated investments on improving port facilities and attracting the mega carriers are immense for all the ports in the region and the extent of the effort could cripple the local ports and region's economy given the limited financial resources. It is, however, impossible to avoid the disastrous possibility that the massive investments could be channeled into the port, which will never become a hub port, as no port is ready to currently admit defeat and settle as a small regional port. In an attempt to minimise such disastrous waste of resources, ports need to verify the eligibility of their own. This paper tests a system dynamics model using the Port of Busan to understand and illustrate the principle guideline of investment decision making for ports.

This paper tries to draw some implications for Korean seaports in terms of management and development of ports with respect to attracting more transshipment container cargoes. For this the results of the Origin-Destination(O-D) analysis between major Korean ports and top 20 Chinese ports were presented. They also contained the O-D analysis between Chinese major ports and their inland hinterlands.

This paper selects length of berth, area of yard, unloading capacity and number of berth as the input indexes, and cargo turnover as output index to research the source of turnover growth of 22 main ports in Korea. We gains the following results: in general, the trade ports in Korea are the stage of expansion period, the sources of turnover growth depends on the growth of factor inputs and could not be supported by TFP and technical progress. Especially in the west and east coast, TFP and technical progress is the block to the turnover growth. Four major factors to the increase of TFP are following: competition between ports, reform of property system, harbor-hinterland economic and international trade, modeling, imitation and innovation in management, technology and system.

This paper is a study of the relationships between trade and transshipment in Korea. Through the analysis of the data collected, a comprehensive model has been developed to analyze and predict relationships between trade and transshipment. By using analyses of port and trade evolution in Asia, the model identifies some important results. An application of the model to forecast developments in selected regions in China is also included in this paper. The paper provides a basis for shipping companies to decide on appropriate transshipment port strategies, and provides important theoretical references for Korean ports' development Supported by Shanghai leading Academic Discipline Project, project Number: T0602.

The paper is devoted to present the Continuum Strong Discontinuity Approach (CSDA) and to examine its capabilities for modeling cracking of concrete. After introducing the main ingredients of the CSDA, an isotropic continuum damage model, which distinguishes tension and compression states, is used to implicitly induce a projected traction separation-law that rules the cracking phenomena. Criteria for onset and propagation of material failure and specific finite elements with embedded discontinuities are also briefly sketched. Finally, some representative numerical simulations of cracking, in plain and reinforced concrete specimens, using the CSDA are presented.

The combustion process is the most important process in the S.I. engine since it determines performance and emissions. As the flame propagates slowly due to EGR or lean mixture, the fast burn system is widely used in the modern engines in order to improve engine performance. As the basic research for the fast burn system of the S.I engine, this study is aimed to identify the effects of the intake port design on the air motion inside a cylinder. In this study various intake ports were designed and tested. Swirl levels for the different intake ports were measured by a swirl meter and LDv.Also transient air motion inside a cylinder is further investigated following the motion of the boston. Out of the various intake ports tested in this study the masked shroud head (MSH) generates the highest swirl while keeping satisfactory volumetric efficiency. The MSH port also produces high level of turbulence by shearing action between cylinder wall and swirl.

중국의 지속적인 경제성장에 따른 중국 물동량의 급속한 성장률은 부산항, 광양항뿐 아니라 동북아 지역의 경쟁상태에 있는 여러 항만들의 환적물동량 유치경쟁을 가속화시키는 원인이 되었다. 따라서 본 연구는 중국으로의 환적화물을 유치하기 위한 효과적인 방안을 제시하는데 목적을 두고 있다. 이를 위하여 첫째, 대중국 환적화 물 유치 경쟁하에 있는 항만들의 선호도를 분석하고 둘째, 대중국 환적화물 유치경쟁하에 있는 동아시아 항만들의 경쟁력을 평가하며 마지막으로 대중국 환적화물 유치를 위한 환적결정요인 중요도 평가를 수행하였다. 본 연구 결과 대중국 환적화물을 유치하기 위한 부산항과 광양항의 가장 우선적인 전략은 시설을 증대하고 서비스의 질을 높이는 것이다. 비용과 지리적 위치는 매우 경쟁력이 있으나 타 경쟁항만에 비해 많은 선호를 받지 못하는 이유는 항만 선호도에 있어서 가장 중요한 요인으로 평가된 시설과 서비스의 경쟁력 부족에 의한 것으로 보인다. 그러므로 부산항과 광양항은 CY의 보관능력을 확장시켜야 하며 충분한 선석과 하역장비를 갖추어야 한다. 또한. 환적화물이 적시에 인도될 수 있도록 필요한 제반 서비스를 제공해야 하며 환적화물에 대한 클레임에도 신속히 반응해야 한다. 그리고 환적화물이 손상되거나 멸실되지 않도록 전체적인 서비스의 질을 높여야 할 것이다.
