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.

This study identified a candidate area and route for construction of a hub & spork system for coastal passenger ships. For this purpose, the characteristics of the hierarchy structure of other transportation and the operating system of coastal passenger ships were analyzed. Evaluation factors for selecting alternative areas and routes for the construction project were then extracted. Secondly, the relative importance of these evaluation factors for alternative routes were calculated using the Analytic Hierarchy Process (AHP) method. Finally, the importance of these evaluation items and quality of the alternative areas and routes were considered to select a primary candidate area and route. Therefore, four evaluation items such as the number of passenger-ship routes, the number of passengers, the number of cars, and the number of residences were extracted, and the Mokpo area was selected as the target area. In addition, four evaluation items such as he number of islanders, the number of local governments, geographical conditions and passenger ship operators were extracted, and the Yeonggwang route was selected as priority candidates for this construction project. Meanwhile, for the expansive implementation, step-by-step promotion is needed along with the expansion of terminal facilities, the securing of large ships, and the introduction of a semi-public system for coastal passenger ships.

According to the survey data during the Japanese Occupation Period, the length of South Korea's coastline is about 11,542km, including the coastlines of mainland and islands. To accurately revise/renew this coastline data through site survey, it will cost great money and time. Also, various development projects such as reclamation works on public waters, constructions of ports/harbors, etc. This paper used aerial photographs, satellite image data and GPS survey data with certain intervals to monitor the change in coastal areas of Songieong, Haeundae, Kwanganri, Songdo and Dadaepo. The local area subjected for this research was limited to areas near Busan. The specific contents of this research include. Launching qualitative/time series analyses on the change of coastal areas using aerial photographs, satellite image data and RTK-GPS surveys.

Collision accidents happen frequently. The majority of ships involved in collisions in the coastal areas of Korea are middle and small size ships. The proportion of collision accidents is only 9% of all types of marine accidents; however, the number of casualties resulting from collisions is 34.4% of all human life damages. Generally, as reported by the people involved in these collisions, the navigation lights of the opponent ships were poor and invisible when the accident happened even though the weather and visibility were good. Furthermore, there are many insistences for poor navigation light conditions of the opponent ship in the bay or harbor. Therefore, it is necessary to analyze the present conditions and safety of navigation lights. Therefore, in this study, we examined the rules and books of navigation lights and compared it to that of other transportation systems, such as aircraft, trains, and road vehicles. Furthermore, we analyzed the current marine traf ic circumstances and ship collision accidents that happened in the past 5 years. Additionally, a questionnaire was prepared to gather the opinion of ship experts and secure the objectivity for improvement methods of navigation lights. Finally, methods to improve the navigation lights on ships were devised.

It is difficult to expect the service improvements such as increased number of sailing and making new ship due to financial difficulty this is caused by deterioration of island dwellers. In addition, the safety of ship operation is also a problem with the supply of good sailors difficult problem of low wages and lack of safety working environment. T It is necessary to ensure the introduction of public operating system in coastal passenger shipping business to secure the public and safety. There are many practical constraints but if we obtain public sea ways, it will be possible to improve the operating system through the implementation from a subsidized line and taking off business licenses of an insolvent enterprise by enhancing safety control.

For the systematic study of Korean Asteroidea the specimens collected from total 69 localities in the South Sea, Korea during the period from April, 1980 to Apirl, 1992 were indentified. As a result, 23 species, 18 genea, 8 families and 5 orders were identified of which two species, Mediaster brachiatus and Stellaster equestris have not been reported in Korea yet. Asterina perctinifera was the commonest species collected from 43 localities of 69 localities. Fifteen species were found in Korea Strait and Cheju Island area, respectively. Fifteen temperate species, 7 tropical species and 3 boreal species were found to be distributed in the South Sea of Korea. The asteroids known so far in Korea tuned out to be 43 species.

해수면 상승 및 인간의 활동으로 인한 해수 침투 영향 반경의 예측 및 모의에 대한 연구는 활발히 진행되고 있으며, 해수 침투 피해를 완화하기 위한 다양한 대응 방안이 시도되고 있다. 하지만 해수 침투 피해 대응 방안 등을 효율적으로 사용하기 위해서는 해수 침투 피해가 가장 활발히 일어나는 지역을 선정하고, 지역 특성에 맞는 대응 방안을 선정하는 과정이 필요하다. 기존의 해수침투 취약성 평가의 방법은 대수층 매개변수의 불확실성, 자료의 결측이 빈번하게 발생하고 있다. 또한, 평가 인자에 대한 자료 수집이 어렵고, 대수층에 대한 매개변수의 불확실성으로 직관적인 평가가 어렵다. 본 연구에서는 서해안의 도서지역을 제외한 연안지역을 대상으로 해수침투 취약성 평가 기법을 개발하였다. 해수침투에 대한 직관적인 해석을 위해 직접적인 영향을 미치는 수문 성분 중 해수면, 지하수위, 함양량, 지하수 이용량을 지표로 선정하고, 행정구역 단위로 자료를 수집하였다. 각각의 자료에 대한 평균, 기울기를 이용하였다. 각각의 인자에 대해서 객관적 가중치 산정 방법인 엔트로피 방법을 이용하여 가중치를 결정하였다. Technique for Order Preference by Similarity to Ideal Solution(TOPSIS)를 이용하여 가장 취약한 지역을 선정하였다. 객관적 가중치 산정 방법을 이용하여 자료를 통해 직접적인 평가 가능하며, 추세 분석을 통해 앞으로의 해수침투 취약성에 대한 전망도 가능하다. 평가 결과를 이용하여 해안의 지하수자원의 지속가능한 운영 관리를 위한 자료로 활용할 수 있을 것이다.
