In this research, we are trying to develop a framework to evaluate the prevention program for Tsunami disaster based on the Multi-agent simulation model. Tsunami has arisen by the earthquake. It happened after flew minutes or few hours when it occurred. It is clear that Tsunami will come after earthquake and from seashore. If we prevent the damage by Tsunami, we should make people who is in the seashore and lived near the seaside escape from there. Moreover we must forecast the escape activity from Tsunami. Former research of this field, some researches try to forecast the escape activity as macro level. However, people who escape from Tsunami is differ from their physical ability and ability of information processing. It needs a more accuracy model to forecast the escape activity of them. Furthermore they make a decision step by step using the various information. Therefore escape activity from Tsunami will describe using an agent based model which can only treat the information processing of human being. In this paper, we develop the evacuation model from Tsunami disaster using the Multi agent based model. The purpose of this study is to analyze the human action pattern when Tsunami occurred, and to make an accurately assessment for damages by Tsunami. The Fujisawa city government is planning and operating the various prevention program far Tsunami. However nobody assess it, because they do not have any simulation models for Tsunami disaster. If they want to set an effective prevention program for Tsunami, they should have any kinds of simulation model. The results of this study are 1) To develop the Multi agent based evacuees escape activity model. 2) Assess the damage of Tsunami in Fujisawa-City.

해양에서 유용물질을 생산하는 미생물을 분리하기 위하여 경상도 지역의 해안에서 시료를 채취하여 총 371 균주의 해양미생물을 얻었으며 전분, CMC 및 단백질 등과 같은 기질에 대한 분해활성을 측정하여 CMC에 대한 우수한 분해 능력을 가진 30균주를 선별하였다. 이들 30 균주를 배양하여 CMCase의 생산능력이 우수한 12 균주를 선발하였다. 이들 해양미생물을 배양하고 섬유소 분해효소를 생산한다고 알려진 B. amyloliquefaciens DL-3와 CMCase의 활성을 비교하였다. 이 중 다대포에서 분리하여 명명한 A-53 균주가 가장 높은 CMCase 활성을 나타를 생산한다고 알려진 B. amyloliquefaciens DL-3와 CMCase의 활성을 비교하였다. 이 중 다대포에서 분리하여 명명한 A-53 균주가 가장 높은 CMCase 활성을 나타내었다. A-53 균주를 16S rDNA partial sequencing 및 gyrase A partial sequencing하여 동정한 결과, Bacillus subtilis subsp. subtilis로 확인되었으며 B. subtilis subsp. subtilis A-53으로 명명하였다.

본 연구의 목적은 빠른 속도로 고령화과정을 겪고 있는 한국의 장수 현상 및 장수지역의 공간적 특성을 파악하는 것이다. 이를 위해 1966년부터 2000년까지의 인구 자료를 이용하여 각 지역의 고령화 현상과 장수도 변화를 파악하였다. 또한 장수의 지역요인을 알아보기 위해 자연환경 및 대도시에 이르는 거리와의 관련성을 분석하였다. 연구 결과 첫째, 호남권 농어촌지역이 전국에서 가장 높은 고령화 수준을 나타내고 있었다. 둘째, 70년대 남부지역 섬과 해안을 중심으로 높은 장수도를 나타내던 것이 최근 내륙의 소백산맥 산간지역으로 이동 확장되어 장수지역의 공간적 확산이 이루어졌다. 셋째, 지역환경요인 분석 결과 기온보다는 강수량과 평균표고가 장수도와 관련성이 높은 것으로 나타났다. 넷째, 대도시의 경우 자연환경요인이 아닌 다른 사회 경제적 요인들 중에서 장수도 인자를 찾아야 함을 시사하는 결과를 얻었다.

Beopseongpo has been one of the most thriving ports of the Jeolla region since the Goryeo Dynasty (918-1392). During the time of King Seongjong (r. 1469-1494) of Choseon Dynasty, a navy garrison had been deployed and the port was named Beopseongjin, as recorded in the 1485 edition of Grand code for state administration (Gyeongguk daejeon). Dangsan forests and Bibo forests have been maintained by local residents since hundreds of years ago. Dangsan forests have been applied to the scale of government and public offices. The objectives of this study were to understand the characteristics of the "Wooded Fortress of Beopseongjin in Yeonggwang" as "Scenic Site No. 22", and to investigate the conservational problem of the wooded fortress of Beopseongjin and seashore. The "Wooded fortress of Beopseongjin in Yeonggwang" consists of a Dangsan forest and two Bibo forests. But, the presence of the Dangsan forest has not been well known to the public. Although the wooded fortress has been somewhat disturbed by cultural activities, the Dangsan rituals have been held until the present every January 15 by lunar calendar. On the other hand, the seashore in front of Beopseongpo plays an important role as a scenic view. It was one of the reason that the "Wooded fortress of Beopseongjin in Yeonggwang" had been designated as a national cultural property of "Scenic Sites". However, the sandbar was reclaimed in 2009 to build commercial buildings. An integrated plan should be prepared to conserve the landscape of "Wooded fortress of Beopseongjin in Yeonggwang", which requires close partnership among local residents, experts, and local government. At present, four new buildings have been built. Although we have lost the sandbar, it is indispensable to secure the visibility of Wooded Fortress of Beopseongjin at the entrance of the village.

The purpose of this study is to examine potential as a geological field course of Odongdo located to the east of Yeosu city, Korea. The total area and the height from the sea level of Odongdo is about 0.13km2 and 42m, respectively. Odongdo area belongs to the Hallyeohaesang National Marine Park, and is famous for rock scenery in the rocky coast and living of rare plants. For this study, diversity of geomorphology and geology was investigated at the sites called as dragon cave, windy area, seal rocks, sunrise viewing platform, second seashore rocks and first seashore rocks along the coast of Odongdo. The results of this study are as follows: A lot of geomorphological and geological resources like sea cliff, sea cave, strata, various sedimentary rocks(conglomerate, sandstone, mudstone), andesite, fault and examples of rock weathering were found in the rocky coast of the study area. These field resources are pertinent to the field work materials for the teaching and learning of geology units in elementary school science. Odongdo is to be recommended as a site of outdoor geological field course for the elementary school students inhabited in Yeosu city and neighborhood area because each site of the rocky coast in this study area has various field work materials and the wide space for observe activities, and is equipped with the facilities as a trail for rock observation.

In seashore, outdoor insulators are polluted due to salty wind and the pollution causes the flashover and failure of electric equipments. As well known, the pollution has a close relation with meteorological factors such as wind velocity, precipitation, wind direction, relative humidity, dew point, etc. In this paper we statistically analyzed the correlation between the pollution and the meteorological factors including snowfall and freezing. The multiple regression analysis was used for the statistical analysis; daily measured equivalent salt deposit density(dependent variable) and the meteorological data(independent variable) were used. From the results of this investigation, we verified the influence of snowfall and freezing on the ESDD, which has been overlooked in the preceding investigation.

This paper aims to clarify the residential quarter organization and housing spatial form of fishing village in Eocheong-do Island. The results are as follows. First, island residential quarter is formed along the coastline, the detached house and the shop house are mainly located in the front of the coastline. Second, the inclination road which connects the northernmost end part and the seashore road is maintained as a road system of a residential quarter from the Japanese colony term until now. Third, It is the feature that Eocheong-do island has the wide width of the front of a site compared with other island residential quarters. Therefore, the frontage wide of a building is also large. Fourth, the entrance of the building where the frontage is mainly located right in the middle, and each rooms are located in the surroundings of it. Finally, the typical community space of Eocheong-do island is Pyeongsang(平床). Pyeongsang is space which receives various functions in inhabitants' life cycle.

Air pollutants were measured eight times from June 1999 to June 2002 on regular ferries cruising across the Yellow Sea between Incheon in Korea and Qingdao or Tianjin in China. PM$_{10}$ and PM$_{2.5}$ were measured as particulate matters and SO$_2$, CO, and NO$_{x}$ were measured as gaseous pollutants. On each route, sampling was made, starting two hour after departure and ending two hour before arrival. Low concentrations of gaseous pollutants that were not much varied according to sampling period and location revealed that atmosphere over the sea was not directly affected by anthropogenic emissions. However, concentrations of fine particles were generally higher than those measured at Deokjeok Island, 50km west of the western seashore, at similar periods. It was believed that considerable influence of China in the form of secondary pollutants was exerted over the sea.a.a.a.
