By Chinese growth, economic development and investment of the West-coast are consisting. Specially, the West-coast area need tourist development and tourism Import for the Incheon and the Pyeongtaekhang of the Gyeonggido Province, China trade through the Chungcheongdo Province area. According to such regional special quality, the railroad tourism industry should be activated. Sunset of tourism infra in the West-coast is high value as representative goods of the West coast. Development of the theme railroad tourism industry that utilize the tide may maximize regional advantage of China and capital region. This research is basis investigation to examine development possibility as sunset theme railroad tourism industry of the West-coast. Scope of this research limited by the sunset theme railroad tourism industry for the Chungchongdo Province area.

This study tries to reveal uplift rates inferred from relative and absolute ages on coastal terrace in the West and South Coasts of South Korea. Uplift rate from relative ages on Pleistocene coastal terrace in the West Coast rangesfrom approximately 0.059 to 0.282 m/ky, while a range of approximately 0.020~0.385 m/ky is calculated from the South Coast, suggesting that the South Coast shows higher rate than the West Coast. Based on absolute ages on coastal terrace during MIS 5 in the South Coast, on the other hand, the uplift rates 1 and 4 have ranges of approximately 0.042~0.062 m/ky and 0.051~0.087 m/ky, respectively, indicating that uplift rate in the South Coast is one-third to one-fourth to that in the East Coast. No research on absolute ages in West Coast terrace and lack of relative and absolute ages in the West and South Coasts are considered as the limit in this study.

This study was conducted bimonthly from February to December 2021 to reveal the ecology of Sargassum thunbergii in the intertidal zone along the coasts of Korea. Separate surveys on the period of embryo formation were conducted from February 2021 to December 2022. The growth of S. thunbergii began to increase in February, reached a maximum in June, and was at a minimum in October. Air vesicles were formed from February to June, April to August, and February to August on the east, west, and south coasts, respectively. Receptacles were observed from April to June on the east coast, but from April to August on the west and south coasts. The earliest release of embryos was observed in late May 2022 on the south coast, followed by early June on the east and west coasts. The average size of leaves, stems, and air vesicles was maximum on the east coast and minimum on the west coast, whereas leaf and internode intervals were maximum on the west coast and minimum on the east coast. Plant length, biomass, and the number of branches showed maximum values in the south coast and minimum values in the east coast.

The purpose of this study was to analyze the regional ripple effects and residents' perceptions of the West Coast Highway on four regions of Chung-nam province. The data was collected through questionnaire interviews with 400 residents in four regions of the west coast area. After data cleaning, the statistical methods used were confirmative factor and cluster analysis with 309 sampled from four regions of Dangjin, Boryong, Seosan and Taean. The results of this study were as follows. First, it is classified, according to the residents' perceptions against the opening of the West Coast Highway, into four groups. Group A is the people who haven't lived there long and mainly consists of relatively young (30's-40's) males, while Group B is the people with lower incomes and middle-aged males (40's) who have lived there for 11 to 20 years. Group C is mainly the people who are middle-aged housewives in their 40's and who haven't lived there long and with a relatively higher income. Group D is the people who lived for less than five years and had lower incomes than other groups. The results show that their perceptions against the influence of regional development differ demographically from each other. In conclusion, it was determined that most of them were concerned that it, coupled with the construction of the West Coast Highway, would damage the surrounding countryside but believed it would contribute to the growth of the region's economy. Whereas groups A and B seem to acknowledge the necessity of regional development and environmental protection, groups B and D appear to be more content with the tourism development derived from the West Coast Highway and are paying more attention to such plans than other two groups.

This study used a GPS tracker to determine characteristics of wintering habitat use by black-tailed gulls on the west coast of Korea. Results of this study showed a southward movement in December and a northward movement in March. The wintering habitat was confirmed to include the southwest coastal island area (Group 1), the inland coastal area (Group 2), and China (Group 3). The wintering home range was the narrowest in October and the widest in December. Home range of Group 1 was increased from November, showing the maximum in December, decreased in February, and then tended to increase again in March. Group 2 showed the widest home range in November and a narrow range of home range from December. Home range of Group 3 showed a mixed pattern of group 1 and group 2. The flight rate was the lowest in January and the highest in March. Day and night flight rates showed significant differences by month. This study identified wintering characteristics of the West Coast population of black-tailed gulls on the West Coast, including their wintering areas, migration periods, and use patterns. These wintering characteristics of black-tailed gull in the west coast area are thought to be affected by environmental factors (such as food resources and fishing activities) and geographical characteristics of the West Coast where many islands are distributed.

2007년 12월 7일 HEBEI SPIRIT호 기름유출 사고로 인해 형성된 타르볼이 12월 27일부터 서남해역에 유입되기 시작하였다. 유입된 타르볼은 해경을 중심으로 한 방제세력에 의해 해상 및 해안에서 제거되었으며, 해상 및 해안에 있어서 각각 0.345톤 및 1,739톤의 타르볼이 수거되었다. 서남해역 타르볼 방제에 동원된 방제인력은 약 2만 5천명의 자원봉사자를 포함하여 총 9만 7천명으로 파악되고 있다. 본 연구에서는 뜰채나 그물 등 서남해권내의 해상과 해안에 유입된 타르볼의 방제에 실제적으로 사용되었던 방제방법들을 소개하였다.

서해지역에서 해안구조물을 위한 설계파는 연안지상측후소의 과거 풍속자료로부터 해상풍의 설계풍속을 산정하고 지역별로 결정되는 취송역으로부터 파랑예측모델을 이용하여 결정하는 방법이 제안되었다. 서해에서 설계파를 지배하는 바람은 북서방향(W~N)의 동기계절풍과 남서(WSW~S) 방향의 하기계절풍 및 태풍이며 해상풍의 풍속은 U$\geq$20m/s의 탄풍에 대하여 연안의 지상풍속의 0.8~0.9배를 나타낸다. 서해의 해안지역은 그 위치여건에 따라 세 지역으로 구분할 수 있으며 각각의 지역에 대하여 설계파산정을 위한 취송역을 결정할 수 있다. 수정된 S.M.B. 법에 의하면 서해지역에서 100년빈도 설계파의 심해유의파고는 4.4m~8.3m, 주기는 8.9초~12.0초의 범위를 보인다.

본고는 지난 12년동안 한국연안에 내습한 태풍 및 각 검조소에 출현한 매년의 최고 이상고조와 1970.8.29∼9.2에 있었던 태풍 빌리호 내습시 남 서해안의 각 검조소에서 얻은 자료에 의하여 해면변화에 대한 사례조사를 시도한 것이다. 한국연안은 매년 빈번한 기상교란 (태풍, 저기압등) 에 의하여 이상고조 또는 기상해일현상이 발생, 항만이나 연안지대에서는 적지 않은 피해를 받고 있으나 이에 관한 조사는 전혀 없었으며, 이후 연안지대의 고도이용이나 연안방재를 위하여 먼저 정확한 사례조사가 필요하다고 본다.

There are two principal routes for the Asia-North America containerized cargo, that of Asia-West Coast and Asia-East Coast. On the West Coast, the Asia-Los Angeles, dominate the commerce, whereas on the Asia-East Coast it's the Panama Canal. Each of these routes has different characteristics. All are similar in that each is the door to the commerce of containerized cargo originating in Asia; each combines maritime and overland transportation; each has important intermodal connections and is able to distribute cargo throughout the West and East Coasts of the United States. Each route also has its port of preference that has the necessary infrastructure, equipment and intermodal connections. For example, in the case of the Port of Los Angeles, in spite of some of its advantages, it has several serious problems due to the interminable containerized cargo traffic that must be solved rapidly and satisfactorily in order to progress. In this paper, we would like to show the problems of two main routes.
