Background: There is considerable evidence that leadership influences workplace safety, but less is known about the relative importance of different leadership styles for safety. In addition, a leadership style characterized by an emphasis and a focus on promoting safety has rarely been investigated alongside other more general leadership styles. Methods: Data were collected through a survey to which 269 employees in a paper mill company responded. A regression analysis was conducted to examine the relative roles of transformational, transactional (management-by-exception active; MBEA), and safety-specific leadership for different safety behavioral outcomes (compliance behavior and safety initiative behaviors) and for minor and major injuries. Results: A safety-specific leadership contributed the most to the enhanced safety of the three different kinds of leadership. Transformational leadership did not contribute to any safety outcome over and above that of a safety-specific leadership, whereas a transactional leadership (MBEA) was associated with negative safety outcomes (fewer safety initiatives and increased minor injuries). Conclusion: The most important thing for leaders aiming at improving workplace safety is to continuously emphasize safety, both in their communication and by acting as role models. This highlights the importance for leadership training programs aiming to improve safety to actually focus on safety-promoting communication and behaviors rather than general leadership. Furthermore, an overly monitoring and controlling leadership style can be detrimental to attempts at achieving improved workplace safety.

The coastal composite fishery has the highest rate of around 30.0% in registered fishing vessels of Korea for the last three years. The risk analysis for the fisher's safety of coastal composite fishing vessels was conducted to serve as a basic data for improving the healthy and safe working environment of fisher using fisher's occupational accidents of the national federation of fisheries cooperatives (NFFC) from 2016 to 2018 (n = 1,105). As a result, the occupational accident occurrence rate of coastal composite fishery was 3.76% in all industries, 7.8 times the rate of that. In addition, death and missing rate was found to have a serious level management to 10.10‱. Among the accidents, 76.0% occurred at sea. The slipping, others and contact with machinery or fishing gear occurred more frequently in order in the frequency of accident occurrence pattern. In the risk assessment using frequency and severity, slipping, contact with machinery and others showed high risk during fishing. The results are expected to contribute to identification and assessment of safety hazard occurred in coastal composite fishing vessels.

Purpose: Cancer patients are at a higher risk of being unemployed or facing difficulty in returning to work (RTW) than individuals without health concerns. The aim of this study is to identify and describe interventions developed specifically to assist cancer patients to RTW after treatment. Methods: A comprehensive search was conducted from September to October 2018 in different international databases: PubMed, Medline, and Embase. Studies using qualitative, quantitative, or mixed designs were included if they satisfied the following criteria: (a) described an intervention to assist cancer patients to RTW during or after treatment; (b) conducted on patients aged 18 and over and diagnosed with cancer; (c) written in English; (d) published in peer-reviewed journals. Results: Fourteen studies met the inclusion criteria. Counseling with physical activity intervention, behavioral training to reduce fatigue, and multi-disciplinary rehabilitation programs were found to be effective. Conclusion: Interventions adopting a multidisciplinary approach were effective for RTW in cancer patients. This literature review emphasizes the need for more tailored interventions based on survivors' needs and characteristics in the RTW field.

Background: The purpose of this study was to identify the influence of workers' perceived workload, accident experiences, supervisors' safety leadership, and an organization's safety climate on the cognitive and emotional risk perception. Methods: Six hundred and twenty employees in a variety of manufacturing organizations were asked to complete to a questionnaire. Among them, a total of 376 employees provided valid data for analysis. To test the hypothesis, correlation analysis and hierarchical regression analysis were used. Statistical analyses were conducted using IBM SPSS program, version 23. Results: The results indicated that workload and accident experiences have a positive influence and safety leadership and safety climate have a negative influence on the cognitive and emotional risk perception. Workload, safety leadership, and the safety climate influence perceived risk more than accident experience, especially for the emotional risk perception. Conclusion: These results indicated that multilevel factors (organization, group, and individual) play a critical role in predicting individual risk perceptions. Based on these results, therefore, to reduce risk perception related with unsafe behaviors and accidents, organizations need to conduct a variety of safety programs that enhance their safety climate beyond simple safety-related education and training. Simultaneously, it needs to seek ways to promote supervisors' safety leadership behaviors (e.g., site visits, feedback, safety communication, etc.). In addition, it is necessary to adjust work speed and amount and allocate task considering employees' skill and ability to reduce the workload for reducing risk perception.

Background: Firefighters are required to use self-contained breathing apparatus (SCBA), which impairs ventilatory mechanics. We hypothesized that firefighters have elevated arterial $CO_2$ when using SCBA. Methods: Firefighters and controls performed a maximal exercise test on a cycle ergometer and two graded exercise tests (GXTs) at 25%, 50%, and 70% of their maximal aerobic power, once with a SCBA facemask and once with protective clothing and full SCBA. Results: Respiratory rate increased more in controls than firefighters. Heart rate increased as a function of oxygen consumption ($V_{O_2}$) more in controls than firefighters. End-tidal $CO_2$ ($ETCO_2$) during the GXTs was not affected by work rate in either group for either condition but was higher in firefighters at all work rates in both GXTs. SCBA increased $ETCO_2$ in controls but not firefighters. Conclusions: The present study showed that when compared to controls, firefighters' hypoventilate during a maximal test and GXT. The hypoventilation resulted in increased $ETCO_2$, and presumably increased arterial $CO_2$, during exertion. It is proposed that firefighters have altered $CO_2$ sensitivity due to voluntary hypoventilation during training and work. Confirmation of low $CO_2$ sensitivity and the consequence of this on performance and long-term health remain to be determined.

Purpose: This study aimed to investigate the correlation between death anxiety, terminal care stress, and job satisfaction of new nurses, as well as to identify factors affecting job satisfaction using descriptive correlations. Methods: This study included 143 new nurses who had 3 to 12 months of experience in terminal care. Data were collected from January to February 2018, and were analyzed using descriptive statistics, t-test, ANOVA, Scheffe? test, Pearson's correlation coefficient, and hierarchical regression analysis. Results: There was a negative correlation between job satisfaction and terminal care stress (r=-.170, p=.043), while death anxiety and terminal care stress were positively correlated (r=.284, p=.001). The following findings demonstrated a significant effect on job satisfaction: lesser the clinical career experience, the lower the job load causing death anxiety and terminal care stress, and the higher the job satisfaction. Furthermore, the explanatory power of these factors was 15.1%. Conclusion: To assist new nurses within three months of joining in clinical adaptation, it is necessary to provide them with appropriate knowledge regarding terminal care through training, and with counseling opportunities for the psychological burdens they experience while caring for dying patients.

Background: Firefighters may experience high environmental temperatures or carry out intensive physical tasks, or both, which leads to increased core body temperature and risk of fatalities. Hence there is a need to remotely and non-invasively monitor core body temperature. Methods: Estimated (heart rate algorithm) and actual core body temperature (ingested telemetric pill) measures were collected simultaneously for comparison during training exercises on 44 firefighter volunteers. Results: Prediction of core body temperature varied, with no specific identifiable pattern between the algorithm values and directly measured body core temperatures. Group agreement of Lin's Concordance of 0.74 (95% Upper 0.75, lower CI 0.73), was deemed poor. Conclusion: From individual agreement data Lin's Concordance was variable (Min 0.11, CI 0.13-0.01; Max 0.83, CI 0.86-0.80), indicating that the heart rate algorithm approach was not suitable for core body temperature monitoring in this population group, especially at the higher more critical core body temperatures seen.

In order to improve the implementation of safety and health education at the site for industrial accident prevention activities, research was conducted to minimize inconvenience and increase utilization by redesigning and developing existing education methods. To date, occupational safety and health education has been conducted without considering the general work characteristics and functional facilities (mechanical, electrical, instrumentation, chemical) of workers (mechanical: turbine, valve, pump, hydraulic system, electrical: generator, breaker, motor, etc.). In particular, plant facilities were classified as mechanical and electrical facilities to improve the methodology for industrial safety and health education for plant maintenance workers. In addition, the "One Page Education Plan" was announced as a learning case because the spread of COVID-19 infectious diseases made it impossible to reduce or control the number of people in all groups and groups. The improvement of this training method will play a major role in improving the effectiveness of safety education in power plant workplaces.

As part of the free semester program, the 'Gardener for a day' program in the Korea National Arboretum was newly developed in 2018. The program was developed as a free semester program reflecting the works of a 'gardener' who performs the planning, preparation, maintenance and management of exhibition gardens. This 'Gardener for a day' program was applied to a total of 106 middle school students in October 2018. Educational elements were extracted from Korea National Arboretum exhibition gardens and career exploration of gardeners. The program was designed to provide education on theory and practices, including watching the gardener video, visiting the gardener booth, meeting with actual gardeners at Korea National Arboretum, visiting two exhibition gardens, and participating in three types of practical training as a gardener. A survey about program satisfaction and education was conducted after the program to analyze the students' satisfaction with the program (contents, management, instructor), free semester program (career planning, occupational attitude, independence), and education (awareness of forest biospecies, preservation will). The analysis showed that the following results: satisfaction with the program (score 4.0), free semester program (score 3.8), and education (score 4.0). Comparative analysis of the pretest-posttest questionnaires showed that there were significant educational effects in career planning, occupational attitude, and awareness of forest biospecies.

Purpose: The purpose of this study was to examine the impact of the working environment on person-centered care for home visiting dementia caregivers. Methods: Participants in this study were 146 caregivers, with the least 6 months of experience working at visiting care centers in Busan, and used a total of 133 questionnaires suitable for analysis. Data were collected from June 9 to July 20, 2023, and were analyzed using descriptive statistics, t-test, ANOVA, pearson's correlation coefficients, and multiple linear regression using IBM/SPSS 27.0. Results: As a result of multiple linear regression analysis, organizational factors (β=-.37, p<.001), job-related factors (β=-.27, p=.001), and religion (β=.18, p<.013) were factors affecting person-centered care of home visiting dementia caregivers, and working environment explained 37% (F=10.63, p<.001) of person-centered care. Conclusion: Based on the results of this study, the exploration of strategies to improve the working environment will be necessary in order to increase person-centered care for home visiting dementia caregivers.
