This study aims at determining psychological elements that influence team coordination between a captain and a first officer in a commercial airline cockpit. It also examines how these elements interact between one another in different team membership settings. It was hypothesized that mutual inclusiveness of differential status among pilots enhances psychological safety and engagement in safety improvement efforts. Survey results based on 254 airline pilots suggest that status (captain, first officer) and mutual inclusiveness (openness between team members) influence psychological safety and mutual inclusiveness moderates the relationship between status and psychological safety. The results also suggest that psychological safety is positively associated with engagement in safety improvement efforts and partially mediates the relationship between mutual inclusiveness and improvement efforts. This study provides insights into antecedents of fostering safety improvement efforts in airline crew teams in which cultural differences and professional hierarchy exist.

The purpose of this study is to identify psychological anxiety factors related to firefighters' field activities and suggest improvement measures. To investigate the actual status of psychological anxiety factors, a survey was conducted on approximately 3,500 current firefighters, and the responses of 505 people who participated in the survey were analyzed. As a research method, frequency analysis and cross-analysis were conducted according to the general characteristics of the participants to determine the actual level of psychological anxiety in each work field and the results were analyzed. As a result of the analysis, it was statistically confirmed that firefighters feel a lot of psychological burden due to legal and institutional inadequacies during dispatch, return, or field activities, and frequent friction with civil servants is also a major cause of psychological anxiety. Therefore, based on the results of this study, it is proposed to establish a permanent legal support team in each city and province, designate and operate a hospital dedicated to psychological treatment, and establish a special provision for traffic accidents during the return of fire trucks so that firefighters can concentrate on their duties without psychological anxiety. do.

Background: To investigate the relationship between musculoskeletal disorders and comorbid health problems, including depression/anxiety disorder, insomnia/sleep disorder, fatigue, and injury by accident, and to determine whether certain physical and psychological factors reduce comorbid health problems. Methods: In total, 29,711 employees were selected from respondents of the Third Korean Working Conditions Survey and categorized into two groups: Musculoskeletal Complaints or Musculoskeletal Sickness Absence. Four self-reported health indicators (overall fatigue, depression/anxiety, insomnia/sleep disorder, and injury by accident) were selected as outcomes, based on their high prevalence in Korea. We used multiple logistic regression analysis to determine the relationship between comorbid health problems, musculoskeletal complaints, and sickness absence. Results: The prevalence of musculoskeletal complaints and musculoskeletal sickness absence due to muscular pain was 32.26% and 0.59%, respectively. Compared to the reference group, depression/anxiety disorder and overall fatigue were 5.2-6.1 times more prevalent in the Musculoskeletal Complaints Group and insomnia/sleep disorder and injury by accident were 7.6-11.0 times more prevalent in the Sickness Absence Group. When adjusted for individual and work-related physical factors, prevalence of all four comorbid health problems were slightly decreased in both groups. Conclusion: Increases in overall fatigue and depression/anxiety disorder were observed in the Musculoskeletal Complaints Group, while increases in insomnia/sleep disorder and injury by accident were observed in the Sickness Absence Group. For management of musculoskeletal complaints and sickness absence in the workplace, differences in health problems between employees with musculoskeletal complaints and those with sickness absence as well as the physical and psychological risk factors should be considered.

This study looks at the impact of psychological and physical factors of the working conditions on the health of workers depending on whether technology is used by such workers. The data used for the study is the third work environment survey. Out of 50,032 respondents, a total of 29,711 paid workers were used as analysis subjects. Although it was anticipated that the use of technology was a factor that hindered job autonomy and teamwork autonomy. However, the analysis results showed low levels of job autonomy and teamwork autonomy in the group that did not use technology. The study assumes a regression analysis model about work environment and work organizational practices of workspaces that have an impact on musculoskeletal complaints, stress symptoms and level of work satisfaction by controlling the social demographic variable that represents the level of individual sensitivity. As a result of the study, ergonomic risk had a significant effect on both groups that did or did not use technology with respect to stress symptoms, musculoskeletal complaints and level of work satisfaction. In particular, as workspace practices and work environment had an effect on the development of musculoskeletal complaints in the group that used machines, there is a need to improve such situation. The autonomous team work or level of job autonomy within the group that used technology may act as a risk factor to the health and welfare of workers. However, because it may also act as a buffer factor, there is a need for a change to reduce stress symptoms and increase the level of work satisfaction by improving autonomous team work and the level of job autonomy.

Purposes: This study aims to investigate the determinants of change-oriented organizational citizenship behavior(CO-OCB) of hospital employees and test the mediating effect of the job satisfaction and organizational commitment on the CO-OCB. Methods: Data were collected from the self-administered questionnaire survey for hospital employees of ten hospitals located in five regions, including Seoul. Out of 1,100 questionnaires which were distributed through the administrative routes, a total of 617 copies were returned(response rate 56.1%) and analyzed by frequency analysis, t-tests, correlation analysis, multiple regression, and path analysis using SPSS 21.0 and AMOS 21.0. Findings: The study results revealed that the explanatory power(56.4%) of the model was most significantly increased by the variables of psychological attributes(R²-change 33,5%). Also, the variables of self-efficacy, followed by hope, the organizational climate for innovation, the psychological safety climate, team-member exchange, and leader-member exchange were found to have positive total effects on CO-OCB, through the mediating variables of job satisfaction and organizational commitment. Practical Implications: The study results imply that, in order to improve the CO-OCB of hospital employees, the administrators have to take the integrated approach considering the various domains of factors including the psychological attributes, job characteristics, interpersonal relations, and organizational climate simultaneously.

Background: The Nordic Safety Climate Questionnaire-50 (NOSACQ-50) was developed by a team of Nordic occupational safety researchers based on safety climate and psychological theories. The aim of this study was to develop and validate the Persian version of NOSACQ-50 and assess the score of safety climate on a group of workers in a steel company in Iran. Methods: The Persian version of NOSACQ-50 was distributed among 661 employees of a steel company in Qazvin Province (Iran). Exploratory factor analysis (EFA) and confirmatory factor analysis were used to determine the dimensions of the questionnaire. The reliability of the questionnaire was assessed using Cronbach ${\alpha}$ coefficient. Pearson correlation test was applied to investigate the correlation between different dimensions. Results: The results of EFA showed that the Persian version of NOSACQ-50 consisted of six dimensions. The Cronbach ${\alpha}$ coefficient of the questionnaire was 0.94. The mean score of safety climate in all dimensions was 2.89 (standard deviation 0.60). Conclusion: The Persian version of NOSACQ-50 had a satisfactory validity for measuring safety climate in the studied Iranian population.

2014년 세월호 침몰사고 이후 해상에서의 안전에 대한 국민적 관심이 높아져 왔다. 해상에서 인명구조에 필요한 초기 대응시간을 확보하기 위해 구조기관의 골든타임뿐만 아니라 조난자도 구조대원이 현장에 도착하기까지 필요한 시간을 확보할 필요가 있다. 본 연구는 유류오염방제정(이하 방제정)에 비치된 오일펜스를 활용하여 다수의 인명들을 구조할 때 조난자의 심리적 안정을 유지하고 안전하게 인명을 구조하는 방안에 대한 연구를 진행하였다. 실 해역 실험을 통해 오일펜스의 측면에 구명줄 설치 시 1 m 당 70 kg 성인 2명의 부력을 유지할 수 있고 양측면에는 4명을 유지할 수 있음을 확인하였다. 또한 오일펜스 상부에 탑승 시 8 m 당 성인 3명에 대한 부력이 유지되고 있음을 확인하였다. 구조 방법으로는 방제정에서 설치한 오일펜스 후단을 잡고 고속단정이 조난자에게 접근시키는 것이 가장 신속하고 정확하게 구조하는 방법임을 확인하였다. 이 결과로 오일펜스를 활용하여 구조기관이 구조에 필요한 시간을 확보하고 아울러 조난자가 구조 시까지 심리적 안정을 가질 수 있어 다수의 인명들을 구조할 때 구조 방안으로 활용할 수 있음을 확인하였다.
