<Objective> This study were carried out to study to assess the relationship between job characteristics, general characteristics,　health behaviors, and psychosocial distress and suggested the preventive oriental medicine approaches in occupational health area. <Methods> We measured job characteristics(job demand, job control, jop insecurity) by The Karasek's Job Content Questionnaire, health behaviors(smoking, drinking, exercise, coffee), general characteristics at work by a self-administered questionnaire. Psycho social distress was measured by PWI(Psychosocial Well-being Index), a 18-item selfadministered instrument. 370 data for research were collected through the process of oriental health examination with questionnaire in workplace. Statistical analysis was done by t test, oneway ANOVA, and hierarchical multiple regression analysis with SPSSWIN (version 10.0) <Results> Among the 152 respondents, the prevalence of high job strain was 27%(41 persons). The Odds ratio of high job strain was 3.11(95 2.12∼4.11), and those of passive group and active group were 2.01(95 0.83∼2.76) and 1.80(95 0.83∼2.76), respectively. Our results supported the association between psychosocial distress and job strain. <Conclusion> The odds ratio of high strain isolated group(high strain group+low social support) was 3.59(95 2.05 5.13), but the odds ratio of high strain collective group was 1.32(95 0.23 2.41). Social support at work was modifing factor of the association between psycho social distress and job strain. Therefore we reviewed the evidence that economic depression was associated with psycho social distress in this study, and that the strength of the social support was important in maintain health.

중력 포텐셜의 해석에 웨이브렛 변환 방법을 적용하였다. 웨이브렛을 만드는 단계 함수가 제안되었다. 단계 함수는 중력 포텐셜에서의 그린 함수로 대치될 수 있음이 보여졌다. 상향연속은 단계함수와의 컨볼루션 곧 웨이브렛 변환으로 표현될 수 있다. 단계인자는 높이 변화를 나타낸다. 다중경계는 각 단계에서의 웨이브렛 변환치의 국부 최대값을 연결하여 구해지며 이는 지층의 불연속면을 나타낸다. 다중경계 방법을 마산 창원지역의 중력자료에 적용하였다.
