본 연구에서는 건축공사의 공정별 공정내용을 파악하고 그에 따라 발생하는 각종 유해요인을 분석하여 공정별 유해요인에 따른 작업환경측정대상과 특수건강진단의 정확한 진단항목 대상을 분석한다. 이를 통한 유해 공정에 따른 정확한 유해요인인자의 파악을 통해 작업환경측정 및 특수건강진단을 유해인자별 정기적으로(산업안전보건법 시행규칙 별표23 특수건강진단의 시기 및 주기를 참조)실시한다면 유해 인자에 따라 표적 추적 검사를 통해 보다 유의한 결과를 측정 가능하며 도출된 결과로 관리적, 공학적, 개인적 개선대책을 세워 관리한다면 직업성 질병을 예방하고, 쾌적한 작업환경을 조성하여 근로자의 안전과 보건을 유지증진 할 것으로 판단되었다. 또한 정기적인 특수건강진단으로 직업성 질병의 예방 및 조기발견으로 사후조치를 적절히 하여 근로자 건강 보호와 노동 생산성 향상을 기대할 수 있을 것으로 기대된다.

직업환경의학은 유해인자의 관리와 그로 인한 건강장해의 예방이 가장 중요하다. 그러나 더욱 중요하고, 선결되어야 하는 것은 문화적인 변화이다. 내가 일하는 곳에서 노동의 가치에 대한 변화를 가져오게 하는 것에 소홀했던 것은 아닌가 다시 한 번 돌아보아야 할 시점이다.

여성근로자들이 작업장에서 당면하게 되는 건강문제들은 주로 화학적환경, 물리적환경, 육체적인 근력을 필요로 하는 작업 등으로 구분되어 다루어지고 있다. 이들 중에서도 특히 연(lead) 과 유기용제 그리고 고열등은 이들에 대한 남성과 여성의 감수성이 다르다는 일반적인 견해들로 인하여 대표적으로 다루어지는 작업장 유해인자 들이다. 동시에 해부학적인 체격의 차이로 인하여 발생되는 근력 및 심폐기능과 관련된 지수들의 차이 역시 특히 물건을 다루는 작업(manual ha­ndling job)들에서는 문제시될 수 있으며 월경 및 임신도 작업수행능력에 영향을 줄 수 있으리라는 것이 일반적인 생각이다. 이들 요인들이 실제로 어느정도 남녀에 대하여 다른 영향을 즐길 수 있는지를 개략적으로 살펴 보면 다음과 같다.

Purpose: Workers with chronic health problems find it difficult to maintain their work because of socioeconomic difficulties. The purpose of this study was to evaluate the relationships between physical, ergonomic, and mental health hazards in the workplace and chronic health problems of Korean workers. Methods: A total of 28,807 wage workers participated in the study and were selected using the Fifth Korean Working Conditions Survey (2017). Multiple logistic regression analysis was used to determine the associations between physical, ergonomic, and mental health hazards and chronic health problems. Results: Of the participants, 1,220 (4.23%) had chronic health problems. Even after adjusting the general characteristics, vibration, noise, high temperature, low temperature, dust, chemical and cigarette smoke, fatigue and painful posture, dragging or pushing or moving of heavy objects, repetitive hand or arm movements, working with a computer or smartphone, use of internet or e-mail, and anxiety situations increased the risk of chronic health problems. Conclusion: The study reaffirms that exposure of physical, ergonomic, and mental health hazards in the workplace significantly increases the risk of chronic health problems.

The types of exposure data needed in an industry-based study depend on the diseases of interest and the study design to be used. The best situation occurs when we have quantified personal exposure estimates for the agents of interest, the least informative case occurs when we have only knowledge of the fact of employment in a plant, industry, or trade where exposure probability is high. Exposure information for most industry-based studies falls somewhere between these tow extremes. Job exposure matrices(JEM) are designed to link information on occupation with information on exposure to specific workplace hazards. Some forms of systematic error of bias may be less likely to occur in studies that utilize job-exposure matrices to indirectly infer exposures from job titles than in studies that assess exposures by asking subjects about their past exposure. JEM can be used effectively in industry-based studies for historic cohort studies, case-control study to assist with the retrospective assessment of occupational exposures among workers whose individual exposure histories are unavailable. JEM generally consist of a computerized database that links information about job categories and likely exposures. These two major axes may be stratified by calendar time. This article reviews the design of JEM in support of industry-based studies. Specific matrices may find broader applicability along with the increasing availability of detailed hygienic data.

Renewable energy industries, including sola cell plants, has been ever increasing ones for reducing fossil fuel consumption and strengthening national energy policy. In this paper we tried to identify occupational health hazards in solar cell-related industries operated in Korea. Poly silicon, silicon ingot and wafer, solar cell and module are major processes for producing solar cells. Poly silicon operations may cause hazards to workers from metal silicon, silanes, silicon, hydro fluoric acid and nitric acid. Solar cells could not be constructed without using metals such as aluminum and silver, acids such as hydrofluoric acid and nitric acid, bases such as sodium hydroxide and potassium hydroxide, and solvent and phosphorus chloride oxide. Workers in module assembly process may exposed to isopropanol, flux, solders that contain lead, tin and/or copper. To prevent occupational exposure to these hazards, it is essential to identify the hazards in each process and educate workers in industries with proper engineering and administrative control measures.

PHAs와 같은 유해유기화학물질의 환경노출에 따른 건강영향을 파악하기 위해서 요중대사산물의 배설량, 유전적감수성 등의 생체지표분석법을 동시에 측정하여 정확한 노출량을 평가하고자 하였다. 또한 직업적, 비직업적 노출인구에 영향을 미칠 수 있는 흡연, 음주, 식이 등의 생활습관과의 상호관련성도 평가하였다. 그 결과 비교적 소량의 PAHs에 노출되는 일반인구에서 요중 1-OHP 및 2-naphthol의 배설량에 가장 큰 영향을 미치는 인자는 흡연이었으며 요중 1-OHP의 배설량은 음주여부, GSTM1 유전자의 다형성에 의해서도 영향을 받음을 알 수 있었다.

This study was performed to investigate the knowledge and attitude of workers in small scale industries on health management, and to provide the basic data for more effective service by the group occupational health service system. The knowledge and attitude of 247 workers and 46 health personnel in the industries scattered around Incheon were investigated from December 1992 to February 1993. The results were summerized as follows ; 1. There were significant differences between the workers and the health personnel by age, sex, marriage status, job-position and education level. 2. The recognition level of the workers to contract work related disease was significantly higher than that of health personnel, and recognition level of the workers on environmental hazards and on the utility of measuring hazards were lower than that of health personnel. 3. The recognition level on the content of the group occupational health service system was significantly different between workers and health personnel, 72.6% of the responses from the workers answered that they did not know what the group occupational healthe service system was, but 82.2% of the responses from the health personnel answered that they knew well what it was. And 79.0% of all respondents thought it was necessary for worker's health. 4. Seventy three percent of the respondents from the workers indicated that they had never taken health education. However, 93.0% of all respondents answered positively for the need of health education to promote their health. 5. Current health service system was judged to be insufficient for the demand of workers for better health. Most of the respondents prefered a formal but flexible health service system and they wanted the periodic health examination to be followed up. It was revealed that despite of poor knowledge, the demand of workers for health service was higher than the current supply. Therefore, this study suggests that educating both health personnel and workers to obtain correct knowledge on the hazards to work enviroment and health management is needed for effective occupational health service.

Gingival inflammation is one of the main causes that can be related to various periodontal diseases. Human gingival fibroblast (HGF) is the major constituent in periodontal connective tissue and secretes various inflammatory mediators, such as nitric oxide (NO) and prostaglandin E₂ (PGE₂), upon lipopolysaccharide stimulation. This study is aimed at investigating the anti-inflammatory and antioxidative activities of Lotus Root extract (LRE) in Porphyromonas gingivalis derived lipopolysaccharide (LPS-PG)-stimulated HGF-1 cells. The concentration of NO and PGE₂, as well as their responsible enzymes, inducible NO synthase (iNOS), and cyclooxygenase-2 (COX-2), was analyzed by Griess reaction, ELISA, and western blot analysis. LPS-PG sharply elevated the production and protein expression of inflammatory mediators, which were significantly attenuated by LRE treatment in a dose-dependent manner. LRE treatment also suppressed activation of Toll-like receptor 4 (TLR4)/myeloid differentiation primary response gene 88 (MyD88) and nuclear factor-κB (NF-κB) in LPS-PG-stimulated HGF-1 cells. In addition, one of phase II enzyme, NAD(P)H quinone dehydrogenase (NQO)-1, and its transcription factor, Nuclear factor erythroid 2-related factor 2 (Nrf2), were significantly induced by LRE treatment. Consequently, these results suggest that LRE ameliorates LPS-PG-induced inflammatory responses by attenuating TLR4/MyD88-mediated NF-κB, and activating NQO-1/Nrf2 antioxidant response element signaling pathways in HGF-1 cells.
