PURPOSES : This study estimates the effects of traffic safety policies (e.g., the Minsik Act) on the seriousness of traffic accidents in children protection zones. METHODS : A difference-in-differences framework in which the change in the gap of seriousness of traffic accidents occurring in children protection zones and those occurring outside the zone before and after the implementation of the Minsik Act was applied. Furthermore, a placebo test, in which the samples are restricted to a specific period, is irrelevant to the time of students going to school. RESULTS : On average, when the factors causing traffic accidents are not controlled, the degree of damage in traffic accidents in children protection zones appears to be more serious The introduction of the Minsik Act has been shown to reduce the damage from traffic accidents in children protection zones. In particular, illegal U-turns and signal violations increased the severity of traffic accidents in children protection zones, and trucks caused the greatest damage. CONCLUSIONS : The traffic safety policy for children protection zones (Minsik Act) is effective in improving traffic safety by simply “strengthening legal regulations.” This strengthens the importance of traffic safety education to prevent drivers from engaging in driving behaviors such as illegal U-turns and traffic signal violations. It is necessary to ensure the traffic safety of children by establishing a truck operation policy that bypasses children protection zones.

Prior studies focusing on safety behavior have not given sufficient consideration to the potential impact exerted by different leadership styles. Of these various styles, my attention is specifically drawn to the influence of ethical leadership on safety behavior. In this paper, I delve into the influence of ethical leadership on safety behavior, shedding light on both the underlying mechanisms(mediators) and a significant contextual factor(moderator). I probe into the successive mediating roles of employees' trust in the organization and their commitment to it, within the context of the relationship between ethical leadership and safety behavior. Further, I posit that authentic leadership positively adjusts the connection between ethical leadership and organizational trust. My findings underscore that ethical leadership enhances employee safety behavior, facilitated by the chain mediation of trust in the organization and organizational commitment. Moreover, I discover that authentic leadership, as a positive moderator, magnifies the favorable impact of ethical leadership on organizational trust. This paper will also articulate the theoretical implications, practical applications, and limitations of the study.

This study has significance in that it found that exposure to harmful/dangerous factors in the establishment and the workers’ experiences of occupational accidents affect their perception of safety culture and that in particular, ‘worker safety priority’ of the safety cultural factors was an important factor, and it is judged that continuous studies are necessary so that the perceptions of safety culture will spread in the establishment.

This paper is the result of a comparative analysis of crew members' workloads using the EMG and OWAS methods according to the fishing process before and after the improvement of the operating system of the experimental vessel, with the aim of improving operational efficiency and safety work of coastal improved stow net fishing vessels. The target crew members were three people with at least five years of experience on board the same fishing vessel as the experimental vessel. After improving the operating system, such as installing a power block crane and two capstans, change the location of the ball-roller, the time required for setting and hauling work decreased (p < .01), and the evaluation results by OWAS showed that the overall workload for setting and hauling net work decreased. The results of muscle activity analysis showed a decrease in lashing anchor work (p < .01) in the case of hauling net and in anchor dropping work in the case of setting net (p < .001). It is judged that the use of ball rollers in net handling has been reduced; consequently, work safety has been improved.

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.

This study examined the certification effects of safety and health management system (SHMS) on the establishment level of SHMS and accident statistics in construction industry. This study obtained the establishment level of SHMS for 106 construction companies surveyed from our previous study. In addition, three major accident statistics (mortality rate, accidental mortality rate, and injury rate) for the companies were collected from the database in Korean Occupational Safety and Health Agency. The statistical analysis results revealed that the establishment level for SHMS certified companies was significantly higher than those for uncertified or certification preparing companies. Furthermore, SHMS certified companies showed significantly smaller accident statistics compared to uncertified or certification preparing companies. The results of this study support the positive effects of SHMS on reducing major industrial accidents in construction companies.

Nuclear power plant’s safety against seismic events is evaluated as risk values by probabilistic seismic safety assessment. The risk values vary by the seismic failure correlation between the structures, systems, and components (SSCs). However, most probabilistic seismic safety assessments idealized the seismic failure correlation between the SSCs as entirely dependent or independent. Such a consideration results in an inaccurate assessment result not reflecting real physical phenomenon. A nuclear power plant’s seismic risk should be calculated with the appropriate seismic failure correlation coefficient between the SSCs for a reasonable outcome. An accident scenario that has an enormous impact on a nuclear power plant’s seismic risk was selected. Moreover, the probabilistic seismic response analyses of a nuclear power plant were performed to derive appropriate seismic failure correlations between SSCs. Based on the analysis results, the seismic failure correlation coefficient between SSCs was derived, and the seismic fragility curve and core damage frequency of the loss of essential power event were calculated. Results were compared with the seismic fragility and core damage frequency of assuming the seismic failure correlations between SSCs were independent and entirely dependent.

This study examined the effects of ‘Dietary education for children’s health UP’ (DECHUP) on the changes in knowledge, attitudes, and practice (KAP) of nutrition and food safety in 5th grade elementary school students in Incheon. The DECHUP program was conducted from May to October 2018 and consisted of education and activities focusing on the children’s levels of understanding. Data were collected before, immediately after, and 6 weeks after DECHUP using the same method. All data were analyzed using SPSS ver 20.0. The level of knowledge and attitudes of the subjects to nutrition and food safety was significantly higher after than before DECHUP, but the attitude of boys did not show any significant difference after 6 weeks. Although there were no significant differences in the behavior for nutrition in the practice of the subjects, there were significant positive changes in the behavior of food safety. The higher the satisfaction of DECHUP, the more positive the change in knowledge, and the more positive the attitude and practice behaviors. Therefore, DECHUP has positive effects on the KAP of the subjects, and it will be helpful for elementary school students to form desirable eating habits if it can be carried out periodically and continuously.

이 연구는 텃밭활동을 통해 중학생이 학교폭력에 노출되지 않는 건강한 학교생활을 지원하기 위하여 사회적 자본을 고려한 정서수준과 텃밭활동의 관련성을 파악하는 데 그 목적이 있다. 이를 위하여 텃밭활동 여건과 학교폭력 관련 정도에 따라 대구, 수원, 서울 등 3개 지역 4개 학교(일반학교 2, 학업중단 및 학교폭력 관련 특수학교 2)를 대상으로 설문조사를 시행하고 192명의 자료를 분석에 활용하였다. 학생과 가정의 사회적 자본과 지역사회 자본이 학교생활 적응에 영향을 미친다는 선행연구를 토대로 사회적 자본을 고려한 정서수준을 측정하기 위하여 14개 항목으로 구성된 조사도구를 개발하여 활용하였고 조사도구의 신뢰도는 .86으로 신뢰할 만하였다. 또 이에 영향을 미치는 변인은 지역사회 변인, 텃밭 관련 변인, 그리고 개인과 가정의 배경변인으로 구분하였다. 지역과 학교에 따라서는 대구의 특수학교 학생이 수원, 서울지역 일반학교 학생보다 상대적으로 정서수준이 낮았고 학생에 게 관심을 보여주는 이웃여부에 따라서도 영향이 있었다. 현재 학교에서 시행하는 텃밭활동 프로그램에 참여하는 집단은 현재생활에 만족하고 지역사회 자원도 더 신뢰하는 것으로 나타났다. 텃밭활동의 접근성, 텃밭활동에 참여하게 된 계기, 텃밭활동에 기대하는 내용(기대변화)도 정서적 수준에 영향을 미쳤다. 직접 또는 간접적으로 학교폭력을 경험한 경우는 그렇지 않은 경우보다 정서 수준이 낮았다. 외롭고 힘든 일에 대한 대처방법, 현재의 고민, 부모(보호자)의 직업, 학교방문이나 자원봉사활동 참여 등이 정서수준에 영향을 미치는 반면에 성별은 영향을 미치지 않았다. 즉 사회적 자본 관련 변인이 정서수준에 영향을 미치고 텃밭관련 변인들의 유용성을 확인하였다. 이 결과는 학교와 가정과 상호 협력하여 지원할 가능성을 탐색하는 데에도 기초적인 정보를 제공할 수 있으며 앞으로 중학생의 여건과 행동반경을 고려하여 지원할 수 있는 텃밭활동 프로그램을 개발하는 데에도 기여할 수 있을 것이다.

위생적인 수확후처리를 통하여 안전한 농산물 생산을 유도하기 위하여 영양부추를 대상으로 수확후 처리시설 모델을 개발하였으며 개발된 수확후 처리시설 설치와 위생교육이 미생물 안전에 미치는 효과를 검증하고자 본 연구를 수행하였다. 이를 위하여 양주지역 영양부추 생산 농가의 수확 후 처리시설 환경과 영양부추에서 위생지표세균(일반세균수, 대장균군, E. coli)과 병원성미생물(Escherichia coli O157:H7, Salmonella spp., Staphylococcus aureus, Listeria monocytogenes, Bacillus cereus)을 조사하였다. 그 결과, 빗, 칼, 도마 등 수확후 처리시설에서 사용하는 작업도구의 일반세균수 오염수준은 수확후 처리시설 설치농가(A, B)에서 수확후 처리시설 비설치농가(C) 보다 1.44~2.33 log CFU / 100cm² 정도 낮았다. 특히 도마의 경우 A농가에서 1.00 log CFU / 100cm²이하, B 농가에서 2.23 logCFU / 100cm²인데 반해 C 농가에서는 6.03 log CFU / 100cm²로 농가간의 위생 상태에 따라 B. cereus의 오염수준이 차이가 크게 나타났다. 또한 지하수에 침지 한 영양부추에서 침지 전 보다 대장균군이 0.57~1.89 log CFU/g이 증가하였다. E. coli는 영양부추, 침지한 후 지하수, 토양에서 검출되었으며, E. coli O157:H7, Salmonella spp., L. monocytogenes는 검출되지 않았다. 따라서 본 연구의 결과를 통하여 소규모 수확 후 처리시설 설치와 위생교육을 통하여 농가 내 수확후처리 환경의 위생을 개선하는데 효과적이라 판단된다. 이와 더불어 유해미생물에 의한 식중독사고를 사전에 예방하기 위해서는 수확 후에 오염된 유해미생물을 저감화 할 수 있는 세척, 소독 기술의 개발과 도입이 필요할 것으로 사료된다.
