농약을 살포하는 농작업자의 농약 노출 측정은 농약의 건강 위해성 평가에서 중요한 부분을 차지하기 때문에 정량적이고 신뢰성 있는 노출량의 측정을 위해서 노출 측정에 사용되는 재료와 기기/기구 및 방법은 포장 노출 시험 전에 미리 검증해야 한다. 본 연구는 유기인계 농약 중에서 살충제 fenthion을 대상으로 농작업자의 노출량 측정을 위한 분석/시험방법의 검증을 수행하였다. LOD는 0.01 ng, LOQ는 0.05 ng로 설정하였고, 표준 검량선의 직선성($R^2$ > 0.999)과 분석재현성(C.V. < 3%)은 매우 우수하였다. 또한 3수준(LOQ, 10LOQ, 100LOQ)으로 수행한 노출 시료(장갑, 양말, 마스크, 패치, 고체흡착제, 유리섬유필터) 중 fenthion의 회수율은 76~113%(C.V. < 3%)이었고, 호흡 노출 실험의 검증 중에서 포집효율은 95~105%이었다. 파과실험 결과 fenthion은 1차 고체흡착제 부분에만 존재하였다. 이와 같은 분석/실험법의 검증을 통하여 실제 포장 실험에서 유래한 노출 시료들을 신뢰성 있게 분석할 수 있는 방법을 확인/검증/확립하였다. 이러한 분석/시험법 검증은 실험실 수준에서 수행할 수 있고, 농약의 종류에 따라서도 크게 다르지 않기 때문에 신체 부위별 평균 체표면적이나, 평균 호흡량과의 조합을 통해서 농약 노출 연구에 적극적으로 활용될 것으로 판단한다.

Coronavirus disease 2019 (Covid-19) poses an important occupational health risk to health workers (HWs) that has attracted global scrutiny. To date, several thousand HWs globally have been reported as infected with the severe acute respiratory syndrome coronavirus 2 virus that causes the disease. It is therefore a public health priority for policymakers to understand risk factors for this vulnerable group to avert occupational transmission. A rapid review was carried out on 20 April 2020 on Covid-19 risk factors among HWs in PubMed, Google Scholar, and EBSCOHost Web (Academic Search Complete, CINAHL Complete, MEDLINE with Full Text, CINAHL with Full Text, APA PsycInfo, Health Source-Consumer Edition, Health Source: Nursing/Academic Edition) and WHO Global Database. We also searched for preprints on the medRxiv database. We searched for reports, reviews, and primary observational studies (case control, case cross-over, cross-sectional, and cohort). The review included studies conducted among HWs with Covid-19 that reported risk factors irrespective of their sample size. Eleven studies met the inclusion criteria. Lack of personal protective equipment, exposure to infected patients, work overload, poor infection control, and preexisting medical conditions were identified as risk factors for Covid-19 among HWs. In the context of Covid-19, HWs face an unprecedented occupational risk of morbidity and mortality. There is need for rapid development of sustainable measures that protect HWs from the pandemic.

산업안전보건연구원에서는 현재 2005년 미국흉부학회(American Thoracic Society, ATS)와 유럽호흡기학회(European Respiratory Society, ERS)의 폐활량검사 표준화가이드를 준용하여 근로자건강진단 폐활량검사를 평가하고 있으며, 2019년 ATS/ERS가이드의 적용을 검토하고 있다. 새로운 평가기준에 따른 결과를 현재 결과와 비교해보고 우리나라 근로자건강진단에 적용하는 것이 적절한지 확인하기 위해 특수건강진단기관으로부터 수집한 325건의 폐활량검사 결과를 검토하였다. 외삽용적, 보정오차, FIVC 등의 평가기준을 더 엄격하게 적용하였음에도 검사의 신뢰성 점수가 상승한 기관이 더 많았다. 주요원인은 FEV1, FVC의 적합성과 재현성을 분리하여 판단함과 동시에 점수를 ATS 등급에 따라 차별 부여하므로 감점 폭이 감소했기 때문으로 파악된다. 새로운 기준을 적용하면 현재 부적합하다고 판단하는 자료의 활용이 가능하므로 검사자와 판정의사의 결과선별과 해석에 대한 이해도를 높인다면 검사자와 수검자 모두가 검사에 대한 부담감을 줄이면서 신뢰성 있는 결과를 얻을 수 있을 것으로 기대한다.

Urbanization rates of population range from about 1% in the developed countries to about 4% in developing countries. For a global population that may reach 10 billion within the next 40 years, pressure has arisen for an increase in the large-scale use of wastes and byproducts in construction. Ironically, most of the wastes that need to be recycled are generated in large cities where the need for constructed facilities to serve large population is high. Waste and recycled materials (WRM) that are used in construction are required to satisfy material strength, durability and contaminant teachability requirements. These materials exhibit a wide variety of characteristics owing to the diversity of industrial processes through which they are produced. Several laboratory-based investigations have been conducted to assess the pollution potential and load bearing capacity of materials such as petroleum-contaminated soils, coal combustion ash, flue-gas desulphurization gypsum and foundry sand. For full-scale systems, although environmental pollution potential and structural integrity of constructed facilities that incorporate WRM are interrelated, comprehensive schemes have not been developed for integrated assessment of the relevant field-scale performance factors. In this presentation, a framework for such an assessment is proposed and presented in the form of a flowchart. The proposed scheme enables economic, environmental, worker safety and engineering factors to be addressed in a number of sequential steps. Quantitative methods and test protocols that have been developed can be incorporated into the proposed scheme for assessing the feasibility of using WRM as partial or full substitutes for earthen highway materials in the field.

The study subjects included the workers who were estimated to have been exposed in a low density of lead-laden glaze from pottery manufacturers. They were evaluated in terms of PbB and PbU as indices of lead concentration in the body, and Hb, Hct, ALAD, and FEP as indices of biochemical lead poisoning. Consequently, the study results revealed the relationship between each of indices and its effectiveness to indicate the degree of occupational lead exposure. 1. The mean of PbB was $22.85{\;}{\mu}g/d{\ell}$(range; $4.2~44.7{\;}{\mu}g/d{\ell}$) and PbU $45.69{\mu}g/d{\ell}$(range; $6.7~87.5{\mu}g/d{\ell}$), to indicate the level of lead exposure in the subjects. 2. While there was a high, linear correlation between PbB, PbU and FEP (r=0.835, r=0.855, respectively), a low correlation existed between PbB and ALAD(r=-0.240). 3. While there was a high, linear correlation between PbU and FEP(r=0.825), a low correlation existed between PbU and ALAD(r=-0.352). The above results suggest that FEP can be used as a highly useful biochemical index of lead poisoning, based on its high correlation with PbB and PbU indicating lead concentration in the body.

Objectives: Radiologists are the service worker with emotional labor who works within a relatively small space of the hospital, dealing with multiple patients. The purposes of this study were to search the turnover intention and job satisfaction through the work of emotional labor of radiologists. Methods: A questionnaire survey was conducted on 109 radiologists working at university hospitals, general hospitals, clinics and other facilities across the domestic. The regions were aggregated according to Quality Function Deployment (QFD) method, which was applied in proportion to the population distribution. A questionnaire was composed of 26 questions which were used in Korean Emotional Laboratory Scale (K-ELS). Results: The overall emotional labor score was $48.3{\pm}15.8$. The most pressing requirement of radiologists to improve emotional labor was the topic about the exchange of colleagues ($75.8{\pm}15.6$ score, ${\beta}=0.78$, p<0.001). Conclusions: In order to resolve the emotional labor of radiologists, it could be necessary to have a meeting through training and workshops where the exchange of colleagues can take place.

Objectives: The objective of the present study was to identify mycobacterial infection in retired dusty workers who were ineligible for medical care benefits for work-related pneumoconiosis. Methods: Sputum samples were collected from 170 retired dusty workers living in Gangwon-do. The mycobacterial culture was grown in 2% Ogawa medium and Mycobacteria Growth Indicator Tube(MGIT). Mycobacterial species were identified using MolecuTech REBA Myco-ID^Ⓡ. Results: Thirty-one(18.2%) out of 170 sputum samples were identified as positive for culture. Among the positive culture samples, eleven(6.5%) were identified as mycobacterial species. The proportion of mycobacteria was M. avium 2.3%(4/170), M. fortuitum complex 1.2%(2/170), M. intracellulare 1.2%(2/170), M. abscessus 0.6%(1/170), M. tuberculosis(MTB) complex 0.6%(1/170), and MYC(NTM except 19 species) 0.6%(1/170). Conclusions: In comparison with previous studies, the incidence rate of tuberculosis(TB) in retired dusty workers who were ineligible for medical care benefits for work-related pneumoconiosis was higher than in close contact with TB patients, workers exposed to silica, and patients with silicosis. And the proportion of non-tuberculosis mycobacteria(NTM) was higher than that of MTB.

Objectives: The aim of this study was to develop an air sampling and analytical method for estimating worker exposure to linear carbonate solvents and to evaluate the method. Methods: The target substances were three linear carbonates: DMC, DEC, EMC. GC/FID was used for sample analysis. Laboratory experiments were conducted to determine desorption solvents and sample capacity, and to evaluate storage stability, accuracy, and precision. Results: Coconut Shell Charcoal (CSC, 100/50 mg) was used as the air sampling media, and a desorption solvent of 5% methanol/95% dichloromethane was selected. Recommended sampling capacities were 1~11 ℓ for DMC, 1~18 ℓ for DEC, and 1~24 ℓ for EMC. The stability of three linear carbonates was demonstrated over 30 days in a refrigerator (4℃). Detection limits were determined as follows: DMC 0.26 ㎍/sample, DEC 0.24 ㎍/sample, and EMC 0.25 ㎍/sample. The total coefficient of variation was calculated as DMC 0.064, DEC 0.079, and EMC 0.07. Conclusions: This sampling and analysis method is suitable for estimating personal exposure to linear carbonates in the workplace.
