Coastal erosion and its impact on human activities as well as the economic damage and environmental conservation of coastal area is one of major concern in the national policies. In this study, we conducted physical investigations to evaluate effects of erosion in the Geojin beach, which is located nearby the Geojin Port, for a detecting of shoreline change and beach cross-sectional area. The results showed that significant coastal erosion of the Geojin beach has occurred by the complex resources of natural factor, such as rising sea level, storm surges, high wave, and man-made construction. Especially, due to the sand supplement from Jasan river, the section which is nearby the estuary of Jasan river is maintained as a stable beach, whereas beach erosion of the other site in GW04 section has been increased indeed. Therefore, we suggest that it is need to continuous monitoring using DGPS and various surveying techniques to prevent beach erosion onto the GW04 section.

Fishermen have higher risk of occupational injuries and disease due to frequent machine usage and direct contact to live biological materials. Moreover, growing elderly workers makes the susceptibility to occupational injuries and disease higher. This study was performed to investigate the occupational safety and health status among fishermen. The interview was carried out at Jumunjin and Geojin ports which were representative port at North East side of Korea. The structured questionnaire were used to interview the fishermen from AM 6:00 to PM 11:00 and total respondent were 97 workers. The results were followed; 7 fishermen of all respondents experienced occupational injuries during their work, 5 fishermen were needed to admission longer than 4 days. The injury types were contusion(4 persons), fracture(1 persons) and amputation(2 persons). The cause of injury might be the lack of caution and the unstability of working condition. These results suggested the ergonomical evaluation of working condition and proper management. But there was limited concern and studies on the policy on occupational safety and health on fishermen. So, further study was required to establish the sound policy of fishermen's occupational safety and health.
