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.

Gut (Shaman ritual) in the west coast area is consisted to sanyang-geori (hunting), tasal-geori, gunwoong-geori those describe from hunting process to preparing animal sacrifices to a deity. The characteristic of gut in the west coast area which are represented for mock hunting and animal sacrifice ritual is practicing at the sibamasturi in Japan. This paper aims to compare a shaman ritual in west coast area in Korea and Japanese Sibamasturi from the comparative folklore point of view. Gut in the west coast area is well known for dividing sacrificial offering: vegetable for sinryeong and meat for singyeong. This division of spiritual deity shows it has different background from agriculture and hunting culture. Hwanghae-do gut has been formed under the various life environments. Therefore, each stage is conducted according to the purpose of the ritual. Sanyang-geori (hunting) represents the scene of hunting in the mountain and by catching live animals and it refers to Gunwoonsin, and will be offered. Animal sacrifice is a positive ritual which get rid of bad luck and pleased deity. Sibamasturi is practiced in mountain area where most of people involve in hunting and agriculture. Therefore, this area has both agricultural ritual and hunting ritual. Sibamasturi is practiced in January (lunar) and it also has meaning of beginning of agriculture and hunting in mountain area. Ground burnt off for cultivation way symbolizesfire ritual and mock hunting as well as animal sacrifice together. These rituals match to farmers of mountain area in the south-east Asia. The gut in the west coast area and Japanese Sibamasturi have common point that mock hunting and animal sacrifice are practiced at both rituals, however, the structure for these two ritual are different. In other word, there animal sacrifice has been formed with different cultural back ground.

Data obtained from a cruise from 4~12 December, 1998 was analyzed to estimate the mixing effects of wind, surface cooling, and tide. A band denoting a mixing area with a temperature difference of less than 1$^{\circ}C$ between the sea surface and the bottom extended 40~60 km from the coast into the open sea, following 125$^{\circ}$ 30\` E in longitude. This band was divided into two areas; a well-mixed area close to the coast and a stratified region in the open sea. The mixing effect due to the wind was only 2%, yet the mixing effect due to the tides was about 68%. This indicates that surface cooling and tides were the major factors involved in the mixing mechanism on the west coast during the cooling season.

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.

It is a recent worldwide trend that erosion characteristics of soil, the resistance factor against scour, are quantified and considered in the estimation of scour depths in fine-grained soils. As part of the efforts, local erosion characteristics on fine-grained soils of the West Coast area are analyzed through scour rate experiments, where a lot of sea-crossing long-span bridges are planned and being constructed in recent years. Four sites including Incheon Bridge, Choji Bridge, Hwankyung Bridge, and Janghang area are finally selected for this study and the scour rate tests are performed using 34 undisturbed soil samples from the sites. The critical shear stresses which represent erodibility of the soil tend to be proportional to the undrained shear strength values. The relative ability of cohesive fine-grained soils to resist erosion is assumed to be higher than that of noncohesive soils. Quantified local erosion characteristics of fine-grained soils in the West Coast area are presented in forms of charts showing relationships between scour rates and shear stresses, and suggested as basic data for the estimation of scour depths and design of bridge foundations in the West Coast area.

The climate of a given region is determined by the combination of the various climatic elements. But among them, the temperature is the most important element to classify the climatic type. The author attempted to classify the climatic types in Korea by making a analysis of the characteristics of temperature distribution. To accomplish the study, the author analyzed the daily and yearly range of temperature, the warmest and coldest months, continentality and oceanicity, thermal anomaly, and relative temperature, etc. The data of 153 weather stations are used for the analysis of the above five criteria. As a result of the study, the climate of Korea can be divided into three types, namely, the continental, coastal and intermediate(or transitional) type. The Pronounced continental type is appeared in the northern part of highland area. And the coastal type is limited to the east and south coast areas, and the southern part of the west coast area. The continentality is larger, and the oceanicity smaller, than those of Siberia, Mongolia and the inland area of China where the continental climate is most remarkable in the world. The reason why the west coast area is more continental than the east coast area may be due to the terrain effect and the warm current going north along the east coastline.

We installed the measurement equipment which measure the equivalent Salt Deposit Density(ESDD) of the domestic coast area in the selected 112 place and investigated the influence of the wind which blow at the point of 500m from coast installing a wind vane, wind gauge for realtime measurement. During september${\sim}$december, 2005, ESDD which passively measured at the point of 50m from coast is maximum C grade in the Homigot of Pohang, B grade in the Gochang and A grade in the remaining point. Also ESDD which is measured in the east coast, west coast respectively is the more the distance being far from the coast to inland, the more ESDD rapidly decreasing but each area of the south coast is difficult to identify the decreased tendency because of very low measurements.

Cloud-to ground lightning and total precipitation over Korean peninsula during the summer monsoon season are studied extensively with a special emphasis on the characteristics of convective precipitation. Ten years (1988-1997) lightning and rainfall data and a temporal and spatial scale of one month and 10$^2$ km$^2$ respectively are used to calculate the monthly number of CG lightning flash count. Monsoonal convective activity is higher over the west coast with maxima at two different regions, one in the northern part which increases nortwestward and the other is at the middle west coast of Korea increasing towards the west coast. East coast represents the minimum value of monsoonal convective activity. In the east coast of Korean peninsula, particularly in the region east of Tae-back mountain, the value of Rain yield, (which is defined as the ratio of total precipitation to CG flash count over a common area), is maximum with an average value of 3$\times$10$^{8}$ kg fl$^{-1}$, while the minimum value of rain yield is occurred in the west of Tae-back mountain, with an average value of 0.8$\times$10$^{8}$ kg fl$^{-1}$. Results show in the west coast stations, nearly 82% of the total rainfall is convective in nature, at the middle of the peninsula 53% of the total rain is convective while in the east coast stations 46% contribution from the convective rain is seen. Kanghwa receives the maximum convective rain while at Ulsan the convective rain is minimum. Correlation coefficient between the total precipitation and CG lightning during the summer monsoon season is 0.54.

Background: The objective of this study was to determine the relationship between soil environmental factors and halophyte distribution in the west coast of South Korea. Soils of our study sites were categorized into two groups: salt marsh and estuary marsh. Results: Salinity was higher in the salt marsh group than that in the estuary marsh group. However, total nitrogen, silt, and clay contents were higher in the estuary marsh group than those in the salt marsh group. Although altitude had a wider range in the salt marsh group, the mean altitude was higher in the estuary marsh group than that in the salt marsh group. Annual halophytes of seed propagation species were distributed parallel to the coast line on salt marsh. Higher coverage of vegetation was found in the area closer to the coast line. Plant density was higher near dead parental plants in estuary marsh, showing less difference in area that was more distant from the coast line. Conclusions: Results of canonical correspondence analysis (CCA) for vegetation distribution and sediment environmental factors and germination analysis in the coast line showed significant relationship with halophyte distribution. Therefore, they can be used as an indicator of coastal plant movement due to sea level rise.
