This study was conducted to verify the impact of hazardous risk factors in manufacturing workplaces on worker safety behaviors, focusing on the mediating effect of safety climate, and to establish safety management strategies in manufacturing workplaces and to suggest practical measures to improve worker safety. For this study, the results of the ‘10th Occupational Safety and Health Survey’ conducted by the Korea Occupational Safety and Health Agency’s Occupational Safety and Health Research Institute in 2021 were used as analysis data for 3,255 manufacturing workplaces with 20 or more regular workers. The data were analyzed using the SPSS 24.0 program for descriptive statistical analysis, validity and reliability verification, correlation and multiple regression analysis, and hierarchical regression analysis. As a result of the study, first, hazardous risk factors were confirmed to have a negative effect on workers' safety behaviors. Second, hazardous risk factors were confirmed to have a negative effect on safety climate. Third, safety climate was confirmed to have a positive effect on workers' safety behaviors. Fourth, it was verified that the safety climate had a partial mediating effect in the relationship between hazardous risk factors and workers’ safety behavior in the workplace. Through this study, it was found that hazardous risk factors had a negative effect on workers’ safety behavior. This emphasizes that efforts to systematically manage and minimize hazardous risk factors in the workplace are important in promoting workers’ safety behavior. In addition, it was confirmed that the safety climate had an important mediating effect in the relationship between hazardous risk factors and workers’ safety behavior. In other words, it can be seen that the safety climate can alleviate the negative effect of hazardous risk factors on workers’ safety behavior. These research results suggest that reducing hazardous risk factors in the workplace and improving the safety climate can have a positive effect on workers’ safety behavior practice, thereby preventing industrial accidents.

This study aimed to quantitatively analyze the risk using data from 329 safety accidents that occurred in aquaculture fisheries management vessels over the recent five years (2018-2022). For quantitative risk analysis, the Bayesian network proposed by the International Maritime Organization (IMO) was used to analyze the risk level according to the fishing process and cause of safety accidents. Among the work processes, the fishing process was analyzed to have the highest risk, being 12.5 times that of the navigation, 2.7 times that of the maintenance, and 8.8 times that of the loading and unloading. Among the causes of accidents, the hull and working environment showed the highest risk, being 1.7 times that of fishing gear and equipment, 4.7 times that of machinery and equipment, and 9.4 times that of external environment. By quantitatively analyzing the safety accident risks for 64 combinations of these four work processes and four accident causes, this study provided fundamental data to reduce safety accidents occurring in aquaculture fisheries management vessels.

This study analyzed effective capacity building education plans for public institution management supervisors. A survey was conducted on 635 management supervisors of public institutions (99 institutions) subject to the safety management rating system to understand the characteristics of educational participants and the impact of educational satisfaction on professionalism improvement after capacity building education. As a result of statistical analysis, the professional improvement according to the affiliation of educational participants was higher in the workplace and construction site divisions than in the research facility division, and the professional improvement according to the working period was higher for more than 15 years than for less than 5 years and less than 15 years. In addition, the quality of education had a significant positive (+) effect on the degree of professional improvement. This study can be used as basic data for further research related to capacity building education for public institution management supervisors

In Korea, from January 2023, the Act on Labeling and Advertising of Food was revised to reflect the use-by-date rather than the sell-by-date. Hence, the purpose of this study was to establish a system for calculating the safety factor and determining the recommended use-by-date for each food type, thereby providing a scientific basis for the recommended use-by-date labels. A safety factor calculation technique based on scientific principles was designed through literature review and simulation, and opinions were collected by conducting surveys and discussions including industry and academia, among others. The main considerations in this study were pH, Aw, sterilization, preservatives, packaging for storage improvement, storage temperature, and other external factors. A safety factor of 0.97 was exceptionally applied for frozen products and 1.0 for sterilized products. In addition, a between-sample error value of 0.08 was applied to factors related to product and experimental design. This study suggests that clearly providing a safe use-by-date will help reduce food waste and contribute to carbon neutrality.

This study analyzed the factors affecting the educational effect of safety innovation education for management of public institutions. A survey was conducted on 294 CEOs and executive directors of public institutions (divided into construction sites, workplaces, and research facilities) subject to the safety management rating system to understand the impact of educational participants' characteristics and behavioral intentions after safety innovation education. As a result of statistical analysis, it was found that the executive director had a higher behavioral intention than the CEO, and the education quality, education instructor, and educational environment all had a significant positive (+) effect on the behavioral intention. This study can be used as basic data for further research related to safety innovation education for management of public institutions

Concerns with colloids, dispersed 1~1,000 nm particles, in the LILW repository are being raised due to their potential to enhance radionuclide release. Due to their large surface areas, radionuclides may sorb onto mobile colloids, and drift along with the colloidal transport, instead of being sorbed onto immobile surfaces. To prevent adverse implications on the safety of the repository, the colloidal impact must be evaluated. In this paper, colloid analysis done by SKB is studied, and factors to be considered for the safety assessment of colloids are analyzed. First, the colloid generation mechanism should be analyzed. In a cementitious repository, due to a highly alkaline environment, colloid formation from wastes may be promoted by the decomposition of organic materials, dissolution of inorganic materials, and corrosion of metals. Radiolysis is excluded when radionuclide inventory is moderate, as in the case of SKB. Second, colloid stability should be evaluated to determine whether colloids remain in dispersion. Stable colloids acquire electric charges, allowing particles to continuously repel one another to prevent coagulation. Thus, stability depends on the pH and ionic condition of the surroundings, and colloid composition. For instance, under a highly alkaline cementitious environment, colloids tend to be negatively charged, repelling each other, but Ca2+ ion from cement, acting as a coagulant, makes colloid unstable, promoting sedimentation. As in the case of SKB, the colloidal impact is assumed negligible in the silo, BMA, and BTF due to their extensive cement contents, but for BLA, with relatively less cement source, the colloidal impact is a potential concern. Third, colloid mobility should be assessed to appraise radionuclide release via colloid transport. The mobility depends on the density and size of colloids, and flow velocity to commence motion. As a part of the assessment, the filtration effect should also be included, which depends on pore size and structure. As in the case of SKB, due to static hydraulic conditions and engineering barriers, acting as efficient filters, colloidal transport is expected to be unlikely. In the domestic underground repository, the highly alkaline environment would lead to colloid formation, but due to high Ca2+ concentration and low flow velocity, colloids would achieve low stability and mobility, thus colloidal impact would be a minor concern. In the future, with further detailed analysis of each factor, waste composition, and disposal condition, reliable data for safety evaluation could be generated to be used as fundamental data for planning waste acceptance criteria.

This study attempted to explore how the perception of the necessity of safety education for adolescents affects fire safety consciousness and whether personality factors control the relationship. To this end, a survey was conducted at a high school in region C, and data of 1,049 people who agreed to the survey and responded faithfully were used for analysis. Hayes’ macro was used to analyze the moderating effect, and as a result of the analysis, adolescents’ awareness of the need for safety education increased, and their relationship was significantly regulated by extroversion, openness, and conscientiousness among the five personality factors. A simple regression line analysis was conducted to find out the specific direction, and it was found that the higher the need for safety education in both the group with high extroversion, openness, and conscientiousness, the higher the awareness of safety education. These results suggest that changes in educational methods and contents are needed to raise awareness of the necessity of education in fire safety education and to improve educational motivation, and that it may be helpful to actively utilize students’ personality strengths in education.

Recently, elevator inspection and self-examination were strengthened through the revision of the Elevator Safety Management Act, but there have been no significant reduction in serious accidents and major failures. Therefore, the government intends to lay the foundation for reflecting the safety quality rating system, which adjusts the elevator inspection cycle, as a policy to induce safety management of preemptive and active management entities. This study systematically reviewed and classified the safety quality rating system for elevator inspection cycle adjustment in previous studies, collected expert opinions, and reconstructed the key items into realistic evaluation items, and evaluated and scored the relative importance of each factor through the AHP technique.

Tuna purse seine fishery (TPF) constitute more than 60% of distant water fishery production in Korea based on a statistic of 2018, and 28 ships from four different companies were under operation at the western and central Pacific Ocean. On this research, common risk factors during TPF were investigated via enumeration of five years Korean fisherman’s insurance payment statement, followed by some counterplans to diminish the accident rate. The accident rate of TPF on the Pacific Ocean peaked by 43.0% in 2014 and constantly decreased to 23.0% until 2018, presenting an average of 33.6%. Meanwhile, the accident rate on the Indian Ocean reached the highest point 55.1% in 2014 and declined to 11.6% in 2016, having an average of 24.7%. The average accident rate of the Indian Ocean scored 8.9% lower than the rate of the Pacific Ocean, but no statistic significance was observed. Depending on the process of operation, ‘casting or hauling of net’ was the most frequent part that people received an injury (40.4%). When the accidents were classified by their types, ‘falling down’ was the most recurrent cause of the injuries (28.5%). At the point of severity, the worst injuries were induced by crush hazard. Considering aforementioned accident frequency and severity, all the factors on the accident type list were divided into three different groups including high risk, moderate risk, and common risk. This study is expected to contribute to the reduction of occupational accidents during the work of fishermen and establishment of a safety management system for distance water fishing vessels.

The purpose of this study is to analyze which factors affect safety awareness of foreign workers and international students. In the correlation analysis, individual characteristics related to the safety awareness of foreign workers were nationality, status of stay(visa types), place of work, educational background, and Korean proficiency while international students were relevant with only the types of residence. There were significant differences in the safety awareness of foreign workers in nationality, status of stay(visa types), region of residence, educational background, place of work, and Korean proficiency. However, there was a significant difference only in the types of residence for the international students. In the regression analysis of factors affecting safety awareness, there were significant differences in nationality, status of stay(visa types), place of work, and Korean proficiency in the case of foreign workers. It was analyzed that nationality and status of stay had a negative (-) effect, and the place of work and Korean proficiency had a positive (+) effect. In the case of international students, it was analyzed that only the types of residence had a negative (-) effect on safety awareness.

Recently, concern regarding disposal of cellulosic material is growing as cellulose is known to produce complexing agent, isosaccharinic acid (ISA), upon degradation. ISA could enhance mobility of some radionuclides, thus increasing the amount of radionuclide released into the environment. Thus, evaluation on the possible impact of the cellulose degradation would be an important aspect in safety evaluation. In this paper, safety assessments conducted in Sweden and UK are studied, and the factors required to be considered for appropriate safety assessment of cellulose is analyzed. SKB (Sweden) conducted safety assessment of cellulose degradation as a part of long-term safety assessment of SFR. SKB determined that ISA would impact sorption of trivalent and tetravalent radionuclides (Eu, Am, Th, Np, Pa, Pu, U, Tc, Zr and Nb) at concentration higher than 10−4–10−3 M, and impact sorption of divalent radionuclides (Ni, Co, Fe, Be and Pb) at concentration higher than 10−2 M. Then, SKB conservatively set the upper limit of ISA concentration to be 10−4 M and conducted cellulose degradation evaluation on each waste package type, considering the expected disposal environment of SFR. Based on the calculated results, some of the waste packages showed concentration of ISA to be higher than 10−4 M, so SKB conservatively developed waste acceptance criteria to prevent ISA being produced to an extent of affecting the safety of the repository. SKB conducted safety assessment only for the repositories with pH above 12.5 and excluded 1BLA from the safety assessment as the expected pH of 1BLA is around 12, which is insufficient for cellulose to degrade. However, SKB set disposal limit for 1BLA as well, to minimize potential impact in future. Serco (UK) conducted safety assessment of cellulose degradation for the conceptual repository, which is a concrete vault with cementitious backfill. Serco estimated that the pH of repository would maintain around 12.4. Serco conservatively assumed that the pH would be sufficient for cellulose degradation to occur partially, and suggested application of appropriate degradation ratio for safety assessment of cellulose degradation. To conduct appropriate safety assessment of cellulose degradation, an appropriate ISA concentration limit based on radionuclide inventory list, and an appropriate cellulose degradation ratio based on the pH of disposal environment should be determined. As for guidance, below pH 12.5, cellulose degradation is not expected, and between pH 12.5–13, partial cellulose degradation is expected. In future, this study could be used as fundamental data to evaluate safety of the repository.

정부(해양수산부) 및 관계기관에서는 안전관리 취약선박의 해양안전 증진을 위한 많은 정책을 시행하고 있으나, 선박의 안전관리에 대한 위험성평가 부재로 각 제도의 효과성에 다소 아쉬움이 확인되었다. 선박의 위험성평가에 대한 국내 선행연구는 대부분 개별적 해양사고 위험성에 대한 단편적 위험성만을 취급하고 있어 포괄적 해양사고 위험성평가를 위한 새로운 방식이 필요하다. 선박의 안전관 리에 대한 포괄적 위험성평가 적용사례로 항만국통제와 노르웨이 해사국의 점검대상 선정방법이 있다. 본 연구에서는 국내 해양사고 및 등록현황의 높은 비중을 차지하고 있는 연근해어선을 대상으로 포괄적 선박안전관리 위험성평가를 위한 지표를 개발하고 적용하였다. 그 결과, 각 선박별 위험성을 계량적 수치로 확인하였고, 개별적 안전관리 취약요소의 순위를 식별하였다.

PURPOSES : In this study, the factors influencing traffic accidents of commercial vehicles in the transportation industry were examined. The evidence observed in this study showed how it contributes to the establishment of safety management policies. METHODS : Safety management data obtained from the Korean Transportation Safety Authority were integrated. A multi-regression analysis was performed by comparing data for the past three years of traffic accident data. RESULTS : Through multi-regression analysis, items that significantly influenced the safety evaluation index (the number of traffic accidents per vehicle owned and the number of dangerous driving actions per 100 km per person) were analyzed. Items with similar patterns observed for various commercial vehicle industries were also analyzed. Monthly average drop off rate, number of law violations per driver, percentage of drivers above 65 years old, percentage of drivers that have completed the compulsory education, number of vehicles owned, and driving distance per vehicle are the variables that influenced the safety evaluation index. CONCLUSIONS : There is a growing need to establish safety management policies and management measures to enhance the voluntary safety management capabilities of the industry. Safety management should be conducted through the analysis of traffic accident impact factors for commercial vehicles.
