  • The objective of this study is to review the methodology of economic analysis of fishing ports by examining the economical feasibilities of a national fishing port (Jeongja Port) in Ulsan. This study utilized market value evaluation method to measure the benefits and costs related to the development of ports. The benefit variables are income effects resulting from the developments while the cost variables are sum of construction costs and maintenance costs. The income effects are measured in two ways: (1) income from individual project resulting from the developments, (2) the income effects by utilizing investment multipliers. The results shows that the BC ratio (Benefits/Costs) of Jeongja port by using (1) income from individual project resulting from the developments was 1.07 while the BC ratio by using (2) the income effects by utilizing investment multipliers was 1.10 due to a relative short period of useful life for investment multipliers. However, the income variable utilizing investment multipliers is more sensitive to the period of duration than the income variable from individual project.

  • In this study, we analysed the state of the fisheries in Chungnam around 1910 from Hangook Susanji. As a result, there were about 30 ports in the west coast area in Chungnam, and we can classify their locations into 5 types Type I is located in small and mid sized rivers. Type II is located in a costal port. Type III is ports facing the open sea, and type IV is ports in a bay. Type V is ports on islands of coast. Species of fish are porges, mackerels, sting rays, croakers, hairtails, shrimps, etc. The base of fishing porge was Jukdo and Yeondo. The fishing banks of croakers are formed from Chilsantan, Jeonlado to the area of seashore, Chungnam. Hairtails were caught near all the areas of seashore. Salt manufacturing is done near all coasts of Chungnam, Seocheon-bay, Ungcheon-bay, Ocheon-bay, Anmyeon island, Taean, Dangjin area, etc represent this work. Especially, the salt which was produced in Taeangun was so famous that it was called ' Taeansalt'. In the Kum-river area there were 32 fishing villages. Freshwater fish were caught in the upper stream area and the mouth of Geumgang, down stream, was the center for producing Baengeo. There were 23 fishing villages, and the species consisted of croaker, hairtail, Forge, gray mullet, sting ray, sharks, anchovy, shrimps, etc in Biin-bay. The coast of Boryeong had about 33 fishing villages, but their fishing industry was not developed more than their good salt manufacturing. Though there are records that Chunsu-bay had 28 fishing villages, Taean peninsula and Garolim-bay had about 70 fishing villages, and Asan-bay area had about 55 fishing villages, they were developed a little, but not more than Weir fisheries or salt manufacture on the base of salt area and the tideland because these areas were just for farming. South of Anmyeon island of West coast island areas is the biggest area of Stow nets on stakes fishing and the island areas down mouth of Kum river were centers for producing porge.

  • Most of fishing ports on the east coast of Korea have constructed around sand beach. Such fishing port structure had caused important effect in erosion of neighborhood sand beach. In order to solve the problems, we have to understand the mechanism through estimations and accurate reproduction beach erosion. Simulataneously, we have to devise a suitable countermeasure for beach erosion to the object coast. This study suggests economically substantial countermeasure for beach erosion around the fishing port and investigates, the preventive effects using a numerical simulation technique.

  • This paper established the analytical model of sea surface oscilation of simple type fishing port with vertical wave absorbor. This model is composed by MAEM(Matched Asymptotic Expansion Method) for wave amplification in fishing port and EEM(Eigen - function Expansion Method) for wave absorbing characteristics against vertical perforated plates. Dimensionless porosity by adopting Darcy's law was introduced to evaluate wave absorbing characteristics of the perforated structure. Using the model, the efficiency of the vertical perforated plates was studied for fishing port tranqulity with number of plates, array method and plate intervals. Optimal design and arrangement of perforated plates can be applied to develop multipurpose fishing ports and villages.

  • This paper suggested the improvement of marine environmental impact assessment in eastern coast as analyzing consultation on the coastal area utilization for development of ports and fishing harbors for 3years in the east coast. The results of survey are only 3cases, 12cases and 16cases each for ocean currents, wave and sounding data. However, for development of ports and fishing harbors in eastern coast, ocean characteristics in eastern coast different than in the West Sea, South Sea is considered to marine environmental impact assessment. For development of ports and fishing harbors in east coast where the influences of ocean currents, wind-driven current and waves are dominant, the effect of the current should be considered to improve the reproducibility of tidal current. The wave should also be considered as an assessment criteria to obtain the validity of project such as harbor tranquility, functionality of breakwaters and stability. In addition, sediment inflow in river and exact water depth data of the ocean should be applied to numerical modeling and set wave-induced current to external force of sediment transport to predict the problems such as the harbor siltation and the coastal erosion considering ocean characteristics in the east coast.

  • This study expresses the necessity of recognizing Pyeongtaek Port as a specific traffic safety area to ensure the safety of the vessels that navigate there using quantitative data. The number of foggy days, pilotage distance, the number of large vessels and the number of fishing vessels that traveled between Pyeongtaek Port and 6 ports chosen as comparative study objects were compared and analyzed. The results showed that Pyeongtaek Port was more frequently affected by restricted visibility. With these perverse conditions, Pyeongtaek Port has a longer pilotage distance than Busan, Busan Newport, Ulsan or Pohang Ports by as much as 3.5-6 times. Especially from May to July, when fisheries were most functional, large vessels were required to navigate in an opposite direction to avoid 35 fishing vessels that were observed, creating an increased possibility for collisions among vessels. Therefore, the navigational safety of Pyeongtaek Port should be further secured by defining the approaching waters as specific traffic safety areas, giving large vessels legal priority over fishing vessels.

  • Most of the short period waves are blocked by the breakwaters when the short period irregular waves propagate into the ports. However, nonlinear irregular wave numerical experiments show that the long waves generated by the nonlinear interaction is predominant in the port. Seiches phenomenon in Geumjin Fishing Port is very similar to 60 and 300 second harbor oscillations. By arranging the inner breakwater of the proper length in the inside of the port, it is possible to effectively reduce seiches, as well as the short-period wave, and significantly improve the harbor tranquility. In the case of rectangular basin type such as the Geumjin Fishing Port, the multi-directional irregular wave numerical model should be used for the investigation and countermeasures for the harbor tranquility.

  • This study describes the spatial distribution of dinoflagellate cyst assemblages from the fishing ports along Jeju Island. Surface sediment samples from 22 stations revealed the occurrence of 29 species involving the Groups Protoperidinioid (44.8%), Gonyaulacoid (31.0%), Calciodineloid (10.3%), Gymnodinioid (6.9%), Diplosalid (3.5%) and Tuberculodinioid (3.5%). The cyst abundance recorded here is very low ($13{\sim}220cysts\;g-dry^{-1}$) as compared to Korean coastal regions. The abundance of heterothophic cysts increased in several fishing pots with fine sediments and anthropogenic tidal pools. And cyst abundance was well correlated with the grain-size composition of surface sediments. The dinoflagellate cyst assemblages in Jeju fishing ports were characterized by the dominant species, cyst of Gymnodinium sp., cyst of Pyrodinium bahamense and cyst of Scrippsiella trochoidea in 2012, Protoperidinium sp. (Brigantedinium sp.), cyst of Scrippsiella sp./trochoidea and cyst of Gymnodinium sp. in 2014, and Protoperidinium sp. (Echinidinium sp. and Brigantedinium sp.) in 2016. The advent of the toxic dinoflagellate, Pyrodinium bahamense were recorded for the first time in Jeju coastal waters. As a results, we are determined should be to monitoring and management measures for new toxic dinoflegallates from tropical or subtropical reigions and anthropogenic tidal pools by industrial activities.
