본 연구는 낙동강 하구역의 사주섬 중 최서측에 위치하는 진우도를 대상으로 실험구를 구축한 후 해안선의 법선 방향으로 정점 5곳을 선정하여 2012년 3월부터 2013년 1월까지 약 11개월간 관측된 수온, 전기전도도, 압력값을 이용하여 지하수위 변동해석을 하였다. 1) 지하수의 수온, 염분, 수위변동과 조위, 파랑, 강수량 등의 외력조건과의 시계열 분석 및 상관분석을 통하여, 조간대정점에서는 파랑 및 조위의 영향, 식생 및 모래지반 정점에서는..

This paper summarized the results of previous and recent studies on cumulative trauma disorders (CTD) and provides a prevention strategy for CTD and showed the results from a quite extensive survey with tables and figures. This is a follow-up study of Kwon (1993) 〔2〕. From the previous studies, Kwon (1993) showed that many people are exposed on CTD, but they did not only know the clear reasons why they got CTD, but also how to prevent or change their workstation〔2〕. Lee (1996) showed the result from both field survey and medical examination. He found that most frequent symptoms are CTS (nerve disorders) and tendon disorders 〔6〕. From these previous results, it is obvious that CTD patients will increase in Korean industries if we did not pay attention to this CTD problem. Therefore a proper education of Ergonomics, CTD prevention for workers and moderate changes in workplace are necessary. From 1998 and 1999 follow-up studies, there are still many people(23％) did not hear about CTD, CTS, or MSD. Only 42％ of respondents is exercising during or after work for short-time. Therefore, there are many rooms for prevention strategy of CTD and education for preventing CTD.
