대한민국 총 인구에서 50세 이상 준고령자가 차지하는 비율은 2010년 29.2%에서 2015년 34.8%로 증가하였다. 이에 따라 전체 건설근로자 대비 50세 이상 건설근로자의 비율은 2010년 20.1%에서 2015년 27.0%로 증가하였다. 이러한 노령화 시대에 맞추어 건설업계에서는 장년근로자들에 대한 재해예방대책을 주어진 사업목표, 예산집행 등을 절차에 맞게 충실히 수행해왔으나 근본적인 재해예방에 한계가 있었다. 이는 건설재해예방의 대책들이 아직까지 장년근로자보다는 전 연령을 고려하고 있기 때문이라 판단된다. 본 연구에서는 건설현장에서의 장년근로자의 안전보건실태를 조사하고 재해감소방안을 제시하였다. 특히 급격히 증가되고 있는 장년근로자의 재해를 감소시키기 위하여 관련문헌 및 안전규정과 산업재해원인통계, 산업재해현황통계 등을 고찰하고, 전국 건설현장에서 공사활동에 직접 참여하고 있는 근로자 3,549명을 대상으로 한 설문조사를 통해 안전보건 실태를 조사, 그간의 재해예방사업 추진현황 및 문제점 분석 등을 통한 재해감소 종합대책을 제시하였다. 본 논문에서 제시한 대책을 실제 정책에 반영할 수 있다면 점진적으로 증가추세인 건설현장에서의 장년근로자 재해를 줄일 수 있을 것으로 기대된다.

Objectives: It has been pointed out that there are problems in handling and managing chemicals due to trade secrets of Material Safety Data Sheet(MSDS). To date, some company intentionally leave out of several parts and use an inaccurate expression in MSDS. In particular, with the result of the inspection of the government and labour community, it is required that the 2nd section in MSDS included the composition and information on ingredients has to be provided with comprehensive expression to secure more reliability. Methods: Therefore, this study is aimed: 1) to recognize the current status of trade secrets of MSDS in workplaces with both domestic manufacturers of chemical products and multinational corporations; 2) to make contributions to prevention of the industrial accidents by providing the accurate information of MSDS; 3) to improve the risk communication system related with chemicals; 4) to impress workers on the importance of right of known for MSDS. With the result we analyzed the status of trade secrets in MSDS in 73 companies, such as petrochemistry production, paint production, metal processing oil production, detergent production, and international company related with chemicals, we have found that 38,150 (45.5%) have the trade secrets parts in the total number of 83,832 in MSDS. Also, based on the 288 MSDS gathered by the Occupational Safety and Health Research Institute (OSHRI) from 2005 to 2009, 41.7% of the MSDS are classified into the trade secrets. Conclusions: Therefore, to procure an assurance system of MSDS, we suggest that a MSDS picking up and checking system be legislated in the Occupational Safety and Health Act to protect workers from the unidentified chemical hazards due to the secret trade of MSDS.

The purpose of this study was to investigate the status of the safety system and safety education in institutional foodservices in the Changwon and Masan areas. The survey was conducted from February 1 to March 31, 2009 via questionnaires that were sent to 300 dietitians, and 142 dietitians responded. It was determined that most of the safety managers were 'dietitians (87.1%)', whereas facilities/equipment managers consisted of 'dietitians (45.7%)', 'department of facilities management in the organization (36.4%)' and 'outsourced company of facilities management (17.9%)'. Out of the 11 safety practices, seven safety practices showed less than 50% of total implementation ratio, which meant that the safety systems were not functioning properly. Except for 'non-skid shoes (85.9%)', other safety equipment was seldom used. The survey respondents recognized that safety education was very necessary (4.47 points); however, they responded so-so (3.46 points) to the question of whether or not the actual frequency and time spent on safety education were enough. The average time spent on safety education was 28 minutes 11 seconds. Regarding the difficulties in performing safety education, 'not many safety education materials and media (3.44 points)', 'not many varieties in the subjects and contents for safety education (3.40 points)', and 'not much organizational support on safety education (3.33 points)' showed higher scores than 'lack of education time due to workload (3.20 points)'. The following were cited as education materials that should be developed as it is currently difficult to obtain relevant information and data: 'root causes of musculoskeletal injury and preventive measures (15.8%)', 'healthcare and disease preventive exercises for employees who do simple and repetitive works (14.9%)', and 'instruction on safe handling of chemicals (12.7%)'

The objective of this paper is to suggest a new quantification method for multi-unit probabilistic safety assessment (PSA) that removes the overestimation error caused by the existing delete-term approximation (DTA) based quantification method. So far, for the actual plant PSA model quantification, a fault tree with negates have been solved by the DTA method. It is well known that the DTA method induces overestimated core damage frequency (CDF) of nuclear power plant (NPP). If a PSA fault tree has negates and non-rare events, the overestimation in CDF drastically increases. Since multi-unit seismic PSA model has plant level negates and many non-rare events in the fault tree, it should be very carefully quantified in order to avoid CDF overestimation. Multi-unit PSA fault tree has normal gates and negates that represent each NPP status. The NPP status means core damage or non-core damage state of individual NPPs. The non-core damage state of a NPP is modeled in the fault tree by using a negate (a NOT gate). Authors reviewed and compared (1) quantification methods that generate exact or approximate Boolean solutions from a fault tree, (2) DTA method generating approximate Boolean solution by solving negates in a fault tree, and (3) probability calculation methods from the Boolean solutions generated by exact quantification methods or DTA method. Based on the review and comparison, a new intersection removal by probability (IRBP) method is suggested in this study for the multi-unit PSA. If the IRBP method is adopted, multi-unit PSA fault tree can be quantified without the overestimation error that is caused by the direct application of DTA method. That is, the extremely overestimated CDF can be avoided and accurate CDF can be calculated by using the IRBP method. The accuracy of the IRBP method was validated by simple multi-unit PSA models. The necessity of the IRBP method was demonstrated by the actual plant multi-unit seismic PSA models.

Recently, the domestic construction companies are increasingly using the scaffolding system in order to secure safety although it may increase the construction cost. However since the actual situation of scaffolding system has not been checked yet, no safety standards and work method were made. Hence, various risk factors are involved in the scaffolding system work. Accordingly, this study is intended not only to check the installation/use status of scaffolding system in the domestic construction sites through the in-depth survey and investigation but also to suggest the measures of using the scaffolding system more effectively and systematically while basing the study results.

Based on five types of health KF masks currently being commercialized, this study analyzed results of a survey of 316 male and female college students with experience in wearing health masks in Seoul metropolitan area. By identifying problems and improvement requirements according to current status of wearing health masks, results of this study could be used as basic data for designing ergonomic health mask with improved ease of wearing and satisfaction for human safety protection in the future. SPSS 26.0 statistical program was used for all data analyses, including post-hoc test, χ² test for cross-analysis, frequency analysis, independent samples t-test, ANOVA, and Duncan test. Considering that masks are worn for more than 8 hours a day on average, it is necessary to design masks considering materials, sizes of mask ear straps, elasticity and thickness of straps. The design should minimize contact with lips and cheeks with improved fit and comfort, blocking performance, and aesthetics. According to this survey, nearly 50% of respondents said they were willing to wear masks even after the end of COVID-19. Thus, it is necessary to perform research and improve masks to have excellent colors, designs, shapes, fit, and functions suitable for both pandemic and post-pandemic era when wearing masks is common.
