  • Korea enacted the occupational safety and health law in order to prevent industrial accidents in 1981. Led by ministry of labor, occupational safety and health support services policy has been built through government-affiliated organizations, research institutions and academic research. Korea's accident rate has remained at 0.7% for last 10 years despite continuous efforts over the last 30 years. These results means that the occupational safety and health support services policy conducted by the government have reached their limits. Therefore, the necessity of assessment about occupational safety and health support services policy is proposed. The main objective of this study, through the IPA analysis, is to grasp the point of worker's needs about occupational safety and health support services policy and to help formulate the efficient policy.

  • A cross-sectional study was performed to evaluate associations between lead biomarkers, lead-related symptoms, and ${\delta}$-aminolevulinic acid dehydratase (ALAD) genotype among 598 lead workers and 144 control office workers in storage battery industries, secondary smelting and litharge making industries. Lead inhibits the second enzymes, ALAD, in the heme synthesis pathway. ALAD gene, which codes for one of three isozymic proteins (termed ALAD1-1, ALAD1-2, and ALAD2-2), seems to modify the toxicokinetics of lead. The result as follows; The percents of total workers whose genotype of ALAD1-1 and ALAD1-2 were 88.4% and 11.6%, respectively. The zinc protoporphyrin in blood (ZPP) and ${\delta}$-aminolevulinic acid in urine (ALAU) of lead workers with ALAD1-2 were significantly lower than those of lead workers with ALAD1-1, but there were no significant difference between two genotype for blood lead, age, and work duration. The proportion of ALAD1-2 genotype in control office workers was 13.2%. The proportions of ALAD1-2 genotype of lead workers were 14.0%(their mean air lead level below $0.024mg/m^3$), 10.4%($0.025-0.049mg/m^3$), 11.8%($0.050-0.099mg/m^3$), and 9.4%(above $0.100mg/m^3$), respectively. In the logistic analysis of 15 lead related symptoms, 'arthralgia'(S7) symptom of ALAD1-2 was significantly lower (OR=0.481; 95% CI=0.248-0.932) than that of ALAD1-1, but 'feeling of irritation'(S11) of ALAD1-2 was significantly higher(OR=1.636; 95% CI=1.035-2.586) than that of ALAD1-1 after controlling possible confounder (blood lead, work duration, smoking and drinking habit).

  • This study is to examine the workers' awareness of the safety in logistic centers. For that purpose, the exploratory factor analysis of workers' safety awareness in logistic centers was performed at first, and the 6 variables extracted from the factor analysis were then used to investigate the difference in intergroup awareness of the safety environment in the logistic centers. We administered a survey to 147 workers attending the logistic centers and collected data from them. The results of the study showed that the intergroup awareness of the safety environment turned out to be statistically different from each other in terms of working environment, safe behavior, work risk, safety knowledge and effort, risk justification and compromising attitudes. Experiences in industrial accidents influenced awareness of working environment, work risk and risk justification. The group who experienced accidents is more likely to feel risky and unsatisfied with working place, and their awareness toward risk justification was high as well. It was also observed that there exists awareness difference between manager group and worker group. The group who manages the working place showed more positive awareness of working environment, safe behavior, work risk, safety knowledge and effort, risk justification and compromising attitudes than the worker group. On the contrary, the worker group showed high recognition in risk of working place, and felt that they are willing to compromise on safety for increasing production. The scale of the logistic center produced negative influence on awareness of safety. The group in small logistic center showed the highest awareness in safety, whereas the group in large logistic center with more than 100 workers showed the highest awareness in risk. They are more likely to deviate from correct and safe work procedures due to over-familiarity with the job, as well. The findings suggest that there is a need for the safety management and education to change the workers' understanding and attitudes towards safety.

The stud}' also aimed at' elucidating' the characteristics of the village health worker organizations developed through community participation in this country. The study methods employed were: a review of literature and other existing information related to VHW's activities ; the use of Questionnaire and interview with VHW's on their activities in one selected county in 1992. The major findings obtained are as follows: 1. So far the community health care activities have been carried out by medical colleges, foreign aid agencies and religious organizations with a view to improving health care for the population in rural area. 2. The VHWs employed by the local community health services received remuneratiorin cash or in kind. However, presently no remuneration is paid to VHWs employed by the government village health projects. The training for VHWs is organized by County Health Center once a year for 1-2days regardless of pre-employment or refresher. 3. The needs of care for maternal and child health and family planning has been decline due to the decrease of the target population, but on the other hand, the needs of care by VHW for prevention of infectious diseases, health of the aging, management of geriatric diseases, prevention of poisoning of pesticides and environmental sanitation has beer increased. 4. It was felt strongly that the training for VHWs should be strengthened by means of developing a problem-solving oriented educational program in order to improve practical skills of VHWs.

  • Purpose: This research aims to investigate into company workers' awareness of scaling and related factors and provide basic materials for setting up appropriate policies to improve the hygiene of the mouth of industrial workers and developing training programs for the worker's hygiene of their mouth, as part of researches to establish schemes for improving the workers's hygiene of their mouth. Method: Questionnaire was conducted by convenience sampling for 220 office workers belonging to H Group located in Seoul Metropolitan city over about 5 weeks between December 17, 2007 and January 20, 2008. The questionnaire for this study was constructed in consideration of general characteristics of the subjects, behaviors of the dental management. and scaling. The collected questionnaires were electronically processed using SPSS 12.0. Result: The followings are the findings of this research. First, in general, scaling is experienced by male unmarried worker in their 40s. whose monthly average income is 1.00-1.99 million won and have little interest in the hygiene of their mouth and, consequently. whose hygiene of the mouth is not good. Second, scaling is experienced once every six months by the worker in their 50s or older, who are college graduates and have much interest in the hygiene of their mouth and, consequently. whose hygiene of the mouth is good. Third. scaling is not periodically conducted because of high costs of it in terms of almost every parameter of general characteristics. Fourth, they have correct knowledge of scaling since they regard it as 'removing of plaque and tartar' in terms of every parameter of general characteristics. Fifth, the workers' sex (pE0.05), hygienic condition of the mouth (pE0.05) and knowledge of scaling (pE0.001) have a significant effect on their scaling experience. Conclusion: It is considered that dental health management should be continued by training of the importance of prevention through scaling as measure for dental health promotion of workers.

  • 근래에 작업자의 근골격계 질환이 산업현장의 주요한 논제로 등장하였다. 이러한 문제를 줄이기 위하여 다양한 방법들이 사용되고 있는데 그 중의 하나가 제품설계, 치구설계, 작업장 설계를 할 때 작업자의 안전을 최대한 확보하도록 설계단계에서 개선을 하는 것이다. 최근에 급속히 발전하고 있는 3D 시뮬레이션 기술을 사용하면 작업장을 설계하는 단계에서 제품 및 치구의 3D 도면을 이용하여 가상의 작업공간을 구축한 후 작업자의 작업 자세를 사전에 검증해 볼 수 있기 때문에 작업장 구축 후 발생할 수 있는 많은 문제점들을 사전에 검증하여 설계실패비용을 최소화할 수 있다. 본 논문은 3D 작업자 시뮬레이션을 이용하여 굴삭기 공장의 특정한 공정을 대상으로 개선 및 최적화를 하기위한 연구다. 먼저 CATIA를 이용하여 제품과 치구 등 작업장 구축을 위한 3D 모델을 개발하였다. 그리고 IGRIP, DPM. Human 등의 개발도구를 복합적으로 이용하여 작업장에서의 작업내용을 시뮬레이션 할 수 있는 모델을 개발한 후 작업 자세에 대한 분석을 수행하였다. 분석결과는 작업장을 개선하는데 이용하였다.

  • This study was conducted to evaluate worker exposure to airborne asbestos fibers by industry, and to evaluate polarized-light microscopy for determining airborne asbestos fibers. A total of 11 plants including asbestos textile, brake-lining manufacturing, slate manufacturing, and automobile maintenance shops were investigated. Rsults of the study are summarized as follows. 1. Worker exposure levels to airborne asbestos fibers were the highest in asbestos textile industry, followed by brake-lining manufacturing, slate manufacturing, and automobile maintenance shops, in order. In asbestos textile industry, large variation of asbestos levels was found by plants. The worst plant indicated airborne fiber concentrations in excess of 10 fibers/cc, however, the best plant showed concentrations within 0.50 fibers/cc. 2. Characterization of airborne fibers by industry indicated that fibers from asbestos textile industry were the longest with the largest aspect ratio. Fibers from automobile maintenance shops were the shortest with the smallest aspect ratio. Based on characteristics of fibers and the highest levels of concentrations, it is concluded that workers in the asbestos textile industry are exposed to the highest risk of producing asbestosis, lung cancer, and mesothelioma. 3. Result s obtained using polarized-light microscopy were $43.7{\pm}12.3%$ of the results obtained using phase contrast microscopy. This may be resulted from the worse resolution of polarized-light microscopy than that of phase contrast microscopy. Based on the results, it is recommended that polarized-light microscopy be used for mainly bulk sample analyses and further study be performed to improve the method for determining airborne samples. However, polarized-light microscopy can be used for determining thick fibers.
