The fact that Pyeongtaek Port is located ideally at the central point of the Yellow Sea's Economic Zone and it is very close to the metropolitan area of South Korea which occupies more than 50 percent of the total trade volume in terms of tonnage is providing a good prospect of development for the Port of Pyeongtaek. This study examines the perception of shippers in Kyonggi-do on the development of Pyeongtaek Port, giving some suggestions to the Pyeongtaek Port Authority. It begins with a description of the port such as current economic status, statistics on the economy, trade and investment regarding the Port of Pyeongtaek. According to a particular questionnaire survey conducted in December 2001, the major obstacles to the utilization of the port are as follows: a shortage of liner shipping routes, lack of container handling facilities including container terminal, crane etc., and port sales promotion activity. Therefore the port should make aggressive efforts to attract container cargoes to and from China by expanding port facilities, implementing effective marketing strategies, introducing a customs-free zone/free trade zone, and strengthening port sales etc.

Because of a recent trend of the open and globalized world economy, international trade is getting bigger and there is a trade competition among many countries, resulting in competition between harbor industries. Therefore, as hub-port development of China, Japan and Taiwan is more actively progressing than any other times, Korea should prepare a powerful management system to take the initiative over them. Above all, a new recognition of the governmental officers in charge of political management about hub-port industry and early development of the northeast hub-port are needed. To maximize its distinctiveness from competitive ports, port sale should be actively managed. As well, as port functions are diverse, accompanied site development should be prepared. In conclusion, in order to improve functions of a port and develop the port as a general complex of physical distribution, the government should encourage the accompanied site development and support preparation of a customs-free area and a general system of physical distribution.

There have been many conflicts in Pyeongtaek-Dangjin Port among central government, metropolitan council, and cities over the jurisdiction of reclaimed port area, an international passenger terminal construction and a bridge between the port and Dangjin area. This study found out two causes for the conflicts in terms of governance. First, the current governance structure of Pyeongtaek-Dangjin port has high levels of conflict and disputes among stakeholder. Second, there is no leading agency which is responsible for the future development of the port. It is very important to decrease the possibility of conflict and to establish leading agency. Measures to decrease the likelihood of conflict include establishment of conflict resolution mechanism, the clarification of the facts and applicable law, mutual exchanges between stakeholder. Measures to establish a leading agency include the introduction of a single governance, establishment of Pyeongtaek-Dangjin Port Authority, central-local combined governance, and empowering PA to do all port management.

In order to propose basic references for the policy making of fishing vessel fishery by Jeju Special Self-Governing Province, we have obtained the basic productivity through analyzing operating days and catches of 16 sample fishing vessels registered in Aewol port, the north of Jeju island in the year of 2011. In addition, to compare with the basic productivity of southern sea area in the Jeju island, that of 7 sample fishing vessels registered in Kangjung port was used. Around Aewol port, average operating days during the main catch period from July to October were over 15 days a month. A average daily catch of fishing vessels was minimum 21.0 kg in May and reached to maximum 54.5 kg in December, showing U-shaped catch pattern through the year. The trend formula of the average daily productivity (y) depending on a tonnage (x) of fishing vessels around Aewol port was described by the equation, y = 18.867 ln(x) + 11.001, and that around Kangjung port in the year of 2009 was understood to be y = 23.271 ln(x) + 25.715. As a result, it seemed that the productivity of fishing vessels around Kangjung port, operating in the southern sea area of Jeju Island, was much greater than that of fishing vessels around Aewol port in the northern sea area of Jeju Island. Especially, that of fishing vessels less than 10 tons was 35-40% more.

Mombasa is the principle port of Kenya, serving inland countries in Eastern and central Africa. Mombasa port has undergone a massive infrastructure upgrade and dredging works with an expectation that more vessels and large post Panamax ships will be able to enter Mombasa port. Therefore, it is vital to carry out a marine traffic risk assessment in order to quantify the degree of navigation safety needed in the Mombasa approach channel and also to evaluate the navigation risk imposed on transit traffic by local ferry traffic. In this paper, a marine traffic risk assessment is carried out using the IWRAP mk2, Environmental Stress (ES) model, and the PARK model. Risk assessment results show that Likoni area has an unacceptable stress/risk ranking at 20.7% by the ES model and 38.89% by the PARK model. The IWRAP mk2 model shows that the crossing area has the highest risk of crossing collision and the area at the entrance to the inner channel has a high risk of grounding. The conclusions derived from this study will provide the basis for proposing the most effective countermeasure to improve navigation safety in the Mombasa approach channel.

Gamcheon Port, which is one of three major harbors in the Port of Busan, is being operated to load, discharge and transport a wide range of cargoes, including general cargo, fisheries, steel products, cement, etc,. The harbor, designated as a compulsory pilotage area, provides pilotage services in compliance with relevant laws and regulations for arrival and departure of vessels in the Gamcheon Port area. Some academic research on the marine traffic environment in Gamcheon Port has been conducted. However, the pilotage environment and hazards to pilotage safety in the port have yet to be studied. Therefore, in this research, the pilotage environment and hazards to pilotage safety were identified, and it was confirmed that there are hazards to pilotage safety, such as vessels installed poor facilities including damaged pilot boarding arrangements, vessels blocking pilot's view by her structures and fishing nets, vessels unable to communicate in English, vessels not following VTS's order. The hazards to pilotage safety were also stratified, and the importance of the hazards was verified in accordance with a survey based on Analytic Hierachy P rocess(AHP) for Busan Harbor pilots, and safety measures to secure pilotage safety were examined to secure the safety of vessels calling Gamcheon Port.

As a key component of a Francis turbine facility, the runner performance plays a vital role in the performance of the turbine. It is effective and successful to design a Francis turbine runner blade with good performance by one dimensional hydraulic design method. On the basis of one dimensional hydraulic analysis, there are a lot of parameters of the internal flow passage shapes determined by experience. Among those parameters, the effect of port area of blade on the performance of a Francis turbine is investigated in this study. A given Francis turbine model was selected for investigating the port area of blade on the performance. The result shows that the effect of port area of runner blade on the outflow angle from runner passage on the performance is quite significant. A correct exit flow angle reduces the energy loss at draft tube, which has the best efficiency of the turbine model.
