  • 우리나라는 국적외항상선의 수가 2006년 1월 기준으로 546척, 13,716,733 G/T에 이르는 세계 제 8위의 해운강국이다. 선박은 건조시로부터 25년에서 30년 정도 운항하면 그 수명을 다해 다른 용도로 변경되어야한다. 수명이 다 된 노후 선박의 처리방법으로 재활용이 가장 나은 방범으로 대두되고 있으나 여러 가지 환경적 규제와 노동 규제에 의해 현재 선진국에서는 거의 이루어지지가 않고 비교적 법규제가 느슨한 개발도상국으로 옮겨지고 있으나 국제적으로는 선박도 하나의 폐기물로 보고 국가간 이동을 금지하는 추세이다. 본 연구에서는 선박해체산업현장의 열악한 작업환경과 환경피해의 심각성 해결을 위한 국제적인 동향을 알아보고자 하였나. IMO, UNEP, ILO 에서는 선박의 해체 작업에 참여하는 작업자들의 건강과 안전을 보호 하고 환경오염을 방지하기 위하여 선박내의 유해물질을 목록화하여 유해물질을 관리하도록 하는 방안을 마련하고 있으며, 선박의 재활용과 관련한 바젤협약, IMO Guideline, ILO Guideline, IMO Convention Draft를 통해 세계적인 추세를 알아보았다.

  • Background: This study aimed to identify the prevalence of workplace hazards and organizational protection resources according to the size of the enterprise in the manufacturing industry of the Republic of Korea. Methods: We analyzed data of waged workers (weighted N = 5,879) from the Fifth Korean Working Conditions Survey (2017). Enterprise sizes were categorized as "micro enterprises" (less than five employees), "small enterprises" (5-49 employees) and "medium-large enterprises" (50 or more employees). Self-reported exposure to 18 physical, chemical, ergonomic, and psychological hazards were measured. The presence of organizational protection resources such as a labor union, a safety delegate working at the company, designated spaces to deal with safety, and the provision of health and safety information was evaluated. Results: Compared to workers in medium-large enterprises, those in micro enterprises showed a higher proportion of exposure to most of physical, chemical, ergonomic, and psychological hazards, except for exposure to solvents, prolonged sitting, and experiencing a state of emotional unrest. On the other hand, workers in micro enterprises had the lowest proportion of access to organizational protection resources. Conclusion: Our study demonstrates that manufacturing workers at the micro enterprise in the Republic of Korea are exposed to the most hazardous work environment and yet have access to the fewest organizational protection resources.

  • 반도체, 디스플레이 등 IT(Information Technology) 제품 수요 증가로 관련 산업이 확대되고 있다. 이는 생산설비 증설과 화학물질 사용 증가로 이어지며 화재·폭발의 위험성에도 영향을 미치고 있다. 이러한 위험요인에 대해 정부는 오래전부터 인화성 물질을 제조·사용·취급하는 장소의 사고 예방을 위하여 산업안전보건법 및 KS 기준에 따라 폭발위험 장소로 설정하여 관리토록 하고 있다. 그러나, 폭발위험장소를 설정할 때, 중요한 요소인 환기량을 고려하지 않아 실질적인 폭발분위기 조성 가능성을 예측하기는 쉽지 않다. 이 연구에서는 디스플레이 산업에서 주요 공정인 CVD(Chemical Vapor Deposition) 설비에 SEMI S6 Exhaust Ventilation Test 방법을 적용하여 위험한 설비의 환기 성능을 평가하고, 폭발분위기 조성 가능성을 확인하였다. 그 결과, 가상의 시나리오 내에서 환기 성능이 SEMI S6에서 규정한 기준에 적합하였고, 폭발분위기가 조성될 가능성이 낮음을 확인하였다. 따라서, KS 규격뿐만 아니라 공학적 기법으로 폭발분위기의 형성 여부를 예측한 연구 결과를 통해 합리적이고 경제적인 사고 예방에 도움이 될 것으로 기대된다.

  • 본 연구는 흡연시 발생되는 각종 유해오염물질을 효과적으로 저감할 수 있는 친환경 흡연부스를 제작하고, 유해물질의 제거효율 및 효과를 평가하는 것이다. 유입구-HEPA필터-전기집진기(EP)-첨착활성탄-배출구 등의 탈취설비를 갖춘 친환경 자동 흡연부스를 설계 및 제작하여, 흡연연기에 의한 유해오염물질의 제거효율을 측정 및 평가하였다. 측정방법으로는 내부의 배경농도, 설비 가동 시 배출구 농도, 10분 후 흡연부스의 농도를 측정하고, 평가항목으로는 복합악취, 일산화탄소, 미세먼지($PM_1$, $PM_{2.5}$, $PM_{10}$), 총휘발성유기화합물(TVOCs)을 대상으로 하였다. 복합악취 제거효율은 흡연부스 내부에서는 95.37%, 방지설비통과 배출구에서는 97.38%로 우수하였다. 일산화탄소 제거효율은 내부에서는 94.25%, 배출구에서는 98.32%로 나타났다. 또 흡연부스 내부에서의 미세먼지 제거효율은 98.59%이며, 배출구에서는 98.85%로 나타나 미세먼지 제거효율은 매우 우수한 것으로 나타났다. TVOCs는 흡연부스 내부에서는 $26,000{\mu}g/m^3$에서 $5,203{\mu}g/m^3$로 감소하여 79.99%의 제거효율로 나타났고, 환풍기 가동 후 방지설비 배출구에서는 $5,019{\mu}g/m^3$로 측정되어 제거효율은 80.70%로 나타났다. 따라서 본 연구를 통하여 제작, 설계된 흡연부스는 향후 소규모 작업환경 내에서도 각종 유해오염물질들을 제거하는 용도로 적용할 수 있을 것으로 생각된다.

  • Objective: In this review we discuss the health effects among office workers. Background: Even if office workers are not exposed hazardous or harmful environment frequently, some problems could be happened to the office workers. Although serious occupational diseases rarely occur to the office workers, it is important to consider occupational risk factors for the office worker because the portion of the office workers is relatively high in all industries. Method: We divided possible health effects for the office workers into three categories; musculoskeletal disorders, indoor environment, and cerebro-cardiovascular diseases. We reviewed related articles, textbooks, and statistical materials non-systematically and described risk factors, related illnesses, and prevention strategies on each category. Results: Office workers have various musculoskeletal disorders to be intervened. By medical treatment, improving working environment, and ergonomic intervention, office workers can be prevented from musculoskeletal injuries. Poor indoor environment can cause many building-related illnesses or sick building syndrome. Although the etiology of some problems by poor indoor environment is not clear, it helps to maintain adequate humidity, temperature, and clarity of indoor air. Cerebro-cardiovascular diseases are a rising issue because office workers in Korea tend to work for a lot of time. To prevent the diseases, it is needed to work for adequate time, lengthen activity level, and manage other medical risk factors for the diseases. Conclusion: There is no distinct occupational disease for office workers. However, there are some aspects to consider the health effects of office workers and it is important to prevent the possible health problems. Application: A strategy against occupational diseases among office workers can be established by reviewing this article.

  • Working in a research laboratory means exposure to a wide range of hazardous substances. Several studies indicated that laboratory workers, especially working with chemicals, might have an increased risk of certain cancers. However, exposure assessment data in laboratory settings are scarce. This study was performed to examine several approaches for quantitatively assessing the exposure levels to volatile organic compounds (VOCs) among workers in chemistry laboratories. The list of 10 target VOCs, including ethanol, acetone, 2-propanol, dichlormethane, tetrahydrofuran, benzene, toluene, n-hexane, ethyl acetate, chloroform, was determined through self-administered questionnaire for six chemistry research laboratories in a university, a government-funded research institute, or private labs. From September to December 2008, 84 air samples were collected (15 area samples, 27 personal time weighted samples, 42 personal task-basis short-term samples). Real time monitors with photo ionization detector were placed during the sampling periods. In this study, benzene was observed exceeding the action levels, although all the results were below the American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Value (TLV). From the air sampling results, we concluded that (1) chemicals emitted during experiments could directly affect to neighbor office areas (2) chemical exposures in research laboratories showed a wide range of concentrations depending on research activities (3) area samples tended to underestimate the exposures relative to personal samples. Still, further investigation, is necessary for developing exposure assessment strategies specific to laboratories with unique exposure profiles.

  • It is essential to consider the heavy industrial working environment factors which are regarded as harmful to workers' health and safety and suitable work motion factors for the workers' motion while developing the work clothes for painting workers in the machinery and shipbuilding industries. This study suggests the use of 3D virtual clothing simulations as a solution to protect the human body from hazardous working conditions accompanying the development of painting work clothes and assessing the work motion performance associated with the comfort while workers wear them during the work clothes. The initial aim of the study is to examine a male avatar to run work motions simultaneously within a 3D virtual clothing simulator, secondly, to present the simulation images of coverall type men's painting work clothes with the application of two experimental painting work motions and one control motion to the avatar, and finally, to present the distance analysis images of the painting work clothes and the avatar body and air gap rates through the analysis of cross-sections of the avatar body while wearing the coverall work clothes according to the work motions. The results showed that the distance degree of painting work clothes to the avatar body for each part of the human body when performing painting work motions. Moreover, 3D virtual clothing simulations enabled the creation of a male model avatar to run painting work motions together and the painting work clothes developed were found to be suitable for the painting work motions.
