In the last ten years, marine geological and geophysical survey and research were conducted by Japanese, Russian and American scientists in the East Sea of Korea (Japan Sea). Many research results were published. However, regional research of the geology of the continental margin of the Korean Peninsula was not conducted. This study has made on attempt to classify submarine strata and stratigraphic boundaries. The study has revealed characters of submarine geology and structure. Isopach maps of each identified stratigraphic unit have been constructed as the results of this study. The study was conducted on the basis of analyses of marine seismic surveys carried out in the continental margin of the East Sea between Kangneung and Pohang. Three depositional basins were identified in the study area and they were named as, Mukho Basin, Hupo Basin and Pohang Basin. The Mukho Basin is developed in continental slope and shelf in the area between Kangneung and Samcheog. Quaternary and Pliocene sediments attain a maximum thickness of 900 m. Basement rocks are interpreted as granite and gneiss. They are correlated with granite-gneiss of the Taebaecksan Series of Pre-cambrian age and the Daebo granite of Jurassic age. The Hupo Basin is developed in the continental shelf between Uljin and Youngdeok. Quaternary and Pliocene sediments attain a maximum thickness of 600 m. Basement rocks were interpreted as granite and gneiss and they are correlated with metamorphic rocks of Pre-cambrian age and the Daebo granites, comprising the Ryongnam Massif. The Pohang Basin is developed in the area between Pohang and Gangu. This basin contains Miocene and older sediments. Basement rocks are not shown. Many faults are developed within the continental shelf and slope. These faults strike parallel with the coast line. A north-south direction is predominant in the southern study area. However, in the northern study area the faults strike north, and north-west. The faults are parallel to each other and are step faults down-thrown to the east or west, forming horst and graben structures which develop into sedimentary basins. Such faults caused the development of submarine banks along the boundary between the continental shelf and slope. This bank has acted as a barrier for deposition in the Hupo Basin. Paleozoic sedimentary rocks distributed widely in the adjacent land area are absent in the Mukho Basin. This suggests that the area of the basin was situated above the sea level until the Pliocene time. The study area contains Pliocene sediments in general. These sediments overlie the basement complex composed of metamorphic rocks, granites, Cretaceous (Kyongsang System) sedimentary rocks and Miocene sedimentary rocks. These facts lead to a conclusion that the continental shelf and slope of the study area were developed as a result of displacements along faults oriented parallel to the present coast line in the post Miocene time.

In an environment where manufacturing conditions such as product lines keep changing, manufacturing control systems need to be continually maintained and upgraded according to the change. This requires an effective system implementation methodology. In this paper, a methodology based on the multi-criteria similarity comparison of manufacturing processes is proposed. A newly introduced process is compared with existing ones based on the multi-criteria similarity, and candidates for software reuse are selected from stored modules according to the overall process characteristics. The proposed methodology has been tested for an electronics manufacturing company's manufacturing control system, and the result has been satisfactory in that it can save time and efforts for system implementation.

In service science, it is critical to measure service satisfaction for innovating service processes, which is challenging for service sectors oriented to the usage of IT systems. For that purpose, in this study, a model based on the technology acceptance model and satisfaction measurement model is proposed. The model is empirically tested using data sets from a public service sector (G2B) and a private service sector (internet banking). The purpose of this study is to identify factors which affect the service satisfaction. The result shows that a public service sector is less sensitive to the IT systems on which its services are operated, and that the attitude factor strongly affects the service satisfaction in both sectors.

Business models of e-commerce which have been successfully applied in a developed society do not always guarantee success in other environments where the degree of IT availability differs. This is due to the difference of culture, systems and technological basis among the countries. This study aimed to compare e-commerce system acceptance in countries with different environments and to identify the determining factors for the acceptance of e-commerce. The result shows that, in order to make e-commerce easily accepted in countries with different IT environments, factors such as trust, reputation and usefulness should be addressed more sincerely in the business strategy.

Evaluating a project is one of the key activities in managing projects, and thus it should be implemented as a part of the entire project management system. However, currently deployed systems suffer from deficiencies such as the lack of supporting distributed environment and integrity problems. Web service technology, which enables applications to work inter-operatively under a distributed computing environment, is said to solve such problems. In this paper, the web service technology is applied to evaluation management systems. The process of evaluation is designed based on the web service, data is modeled and a pilot system is implemented to test the feasibility of the technology to the domain of project evaluation.

The Purpose of this study is investigate the trend of sports injury status in the Korean Delegation players during the 5 Olympic Games from 1984 to 2000. The subject of this study is total 1503 members of Korean Delegation Players participated in 5 Olympic Games. The situations of the Sports injury is divided into 9 causes of sports injuries during the Olympic games with double and triple causes and the mechanism of injury is divided into 3 mechanisms and mixed mechanisms according to the previous investigations by the researchers. 1. The Korean delegation players of recent 5 Olympic games are 1503 members and there was no remarkable difference in Sports injury variations between the events. 2. Ages of the participants was vary from 13 to 39 years old, and the average age is 22.99 years old. The biggest age group was from 21 to 24 years old, were 710 members(47.1%) of all players The distribution was no trend to higher or younger, and even wider or closer. It was due to entries of the Olympic games is not always same. 3. The sex ratio of the participants was 988 for male(65.7%) versus 515 for female players(34.3%) Incident rate between sex was 5981% for male, 67.18% for female players. No remarkable difference between the years by sex and events by sex. (p<0.05) 4. The mechanism of injuries was classified into 3types - rotation, stretch, traumatic and its association. rotation injury was 157 cases(10.4%), Stretch injury was 300 cases(20%), traumatic injury cases was 27(1.8%), and it's association - rotation the stretch injury was 275 cases(18.3%). No remarkable difference between the injury mechanism with age and events (p<0.05) 5. The causes of the Sports injury is divided into 9 causes of sports injuries during the Olympic games with double and triple causes according to the previous investigations by the researchers. Sports injury due to single cause was 934 cases (66.4%), double causes was 505 cases(33.6%), triple causes was 78(5.2%). In whole, olympiad sports injury in Korean delegation due to muscular imbalance was 398(26.4%), lack or warming up or warming down was 387(25.7%), over load or fatigue was 180(11.9%), lack of consciousness was 143 cases(9.5%), exercises fitness was 133(8.8%), training errors was 99(66%), foul play was 68 cases(4.5%), technical problem was 57(3.8%), environmental problem was 17(1.6%) cases No remarkable difference between the age and events by injury causes. (p<0.05) 6. The trend of injury mechanism and injury causes was quite similar even in every 4 years of olympic participants. The main problem of Korean delegation of sports injury is still under predictable causes and known mechanism. The soft tissue problems and preparation defects are internal causes.
