In this paper, we propose a simulation method based on backward simulation and process-oriented simulation to take into account the characteristics of shipbuilding production, which is an order-based industry with a job shop production environment. The shipyard production planning process was investigated to analyze the detailed process, variables and constraints of mid-term production planning. Backward and process-centric simulation methods were applied to the mid-term production planning process and an improved planning process, which considers the shipbuilding characteristics, was proposed. Based on the problem defined by applying backward process-centric simulation, a system which can conduct Discrete Event Simulation (DES) was developed. The developed mid-term planning system can be linked with the existing shipyard Advanced Planning System (APS). Verification of the system was performed with the actual shipyard mid-term production data for the four ships corresponding to a one-year period.

Technostress management is increasingly getting important as ICT advances and infiltrates every job and task. Especially with the advent of COVID-19, workers had to switch to teleworking utilizing ICT extensively. In this study, we developed a research model explaining antecedents and their impacts on technostress in telecommuting context, especially under the COVID-19 situation. The result revealed that techno-complexity, techno-invasion, and techno-overload are the dominant factors that affect the negative psychological responses in the COVID-19 situation. Among them, we found that techno-overload maintain the most significant influence. It is due to the lack of instant feedback on workload allocations in telework and the lack of adjustment period with the sudden shift to telecommuting. In the case of techno-complexity, employees seem to experience difficulty acquiring new technical skills. Finally, the techno-invasion came out significant, signifying the infiltration of working space by home-related activities. The emotion-focused coping strategy had a moderating effect. In contrast, the problem-focused coping strategy had no significant effect, indicating that an appropriate emotional coping strategy is more important for workers undergoing extreme changes in the work environment. Subsequently, practical and theoretical implications, limitations, and future research directions are discussed.

The composition of human resources in industrial sites is becoming global. In Korea, too, the proportion of foreign members in all industrial fields and production sites is increasing. This is the reason why an approach that reflects this reality is needed in the basic unit of competitive sources. Competitiveness starts with value creation, and this progresses through field innovation. Through empirical analysis of this study, it was analyzed that South Korea members showed active actions and attitudes in developing, promoting, and realizing ideas when they strongly recognized the real meaning of empowerment given by leaders. On the other hand, it was found that foreign members do not know the meaning of empowerment itself, so they are often unable to play an active role in the development, promotion, and realization of ideas. In fact, it was analyzed that foreign members generally did not experience positive interactions with LMX and were exposed to simple tasks and controls. In other words, they are being discriminated against in terms of communication problems, compensation system, and work environment. In particular, this phenomenon is exacerbated in the case of small and medium-sized enterprises (SMEs). Situational response to foreign workers through improvement of LMX and empowerment should be evaluated as a key management task in a situation where productivity improvement and job unit innovation are urgently needed.

Background: Industrial accidents can determine the overall level and quality of the work environment in industries and companies that contribute to national economic development. Korea has transformed the country from an international aid recipient to a donor country, but it has ranked first among the Organisation for Economic Co-operation and Development member countries in the number of fatal industrial accidents. Little has been known about the policy effects in terms of the workers' insurance for their industrial accidents and rehabilitation. This study raises two research questions about the influence of workers' personal characteristics and vocational rehabilitation services on their return to workplaces. Methods: The study implements weighted logistic regression analysis using propensity score matching. This research utilizes the relevant dataset (3,924 persons) of Korea's industrial accident and insurance. Results: The findings show that the level of workers' awareness of health recovery and their counseling for rehabilitation by physicians had positive effects on their return to work. Environmental factors such as workers' job stability at the time of industrial accidents and the temporal effects of industrial accidents (e.g., the level of disability, their age) had negative impacts on their return to work. Conclusions: These findings have policy implications that the concentration of rehabilitation services for patients who have been mildly affected by industrial accidents would be effective in the short and medium term. The findings also highlight the necessity of ongoing policies about workers' vocational recovery with concrete evidence about policy impacts.

Maritime transportation is one of the most complicated and hazardous business fileds. Maritime accidents still occur despite several precautions since maritime is exposed to natural factors more than any other industries. In this harsh environment as a part of their job, marine pilots often embark/disembark to/ from vessels and confront life-endangering personal accidents. In the maritime field, several risk assessments are applied. However, all of them could not evaluate occupational accident risk for maritime pilot specifically. This paper performs specific risk analysis using the bow-tie method based on past accident records. This paper aims to qualify root causes and quantify root causes by importance level according to occurrence probability. As a result of analysis, occupational accident occurrence probability is found to be 14%, indicating that accident occurrence rate is significantly high. Hence, the probability of root causes triggering accidents and accident occurrence probability can be ascertained so that preventive measurements can be implemented. Besides theoretical achievement, this paper provides safety awareness to marine pilots, Marine Pilot Organizations, and ship crew who play a key role during marine pilots' transfer.

This study attempted to grasp the current status of field training in the Department of Library and Information Science and the training institutions of the students of the Department of Library and Information Science and to propose a development plan based on this. To this end, a questionnaire survey and survey were conducted on the status of field practice in the Department of Library and Information Science at 4-year and 2-year colleges. As a result of the study, first, it was analyzed that field training has an effect on the employment competitive- ness and employment competency of students, and the field training environment has an effect on career decisions of students in the Department of Library and Information Science. Second, it was found that the library with the most field training was found to be a public library, and it was investigated that in order to allow students to experience various institutions and choose their career path, it was necessary to jointly discover and use field training institutes. Third, the evaluation contents or evaluators of the field training did not show a big difference by school, and it was found that most universities are evaluating the field practice using various scales. Lastly, in order to maintain the level of on-the-job training to some extent, it is necessary to develop a training manual and distribute it to each university.

Purpose: This study was conducted to identify the professional competency of nurses working in emergency medical institutions that use the Korean Triage Acuity Scale (KTAS), and to identify factors that affect them. Methods: This study collected data from 105 nurses working in emergency medical institutions from June to August 2020. For data analysis, descriptive analysis, t-test, ANOVA, Pearson's correlation coefficient, and multiple regression were performed using the SPSS 25.0 program. Results: As for the professional competency in triage, the higher the self-efficacy (β= 0.58, p< .001), the more experience they have in triage-related education (β= 0.30, p< .001), 2-4 years of clinical experience in emergency department (β= 0.19, p= .002), in case of triage alone (β= 0.24, p< .001), the higher the level of education a nurse has (β= 0.19, p= .003), the higher the professional competency in triage. These variables explained professional competency in a total of 64.2% of the participants (F = 38.30, p< .001). Conclusion: To improve nurses' professional competence in triage, introducing manpower expansion, financial support, and the provision of appropriate places is suggested. In addition, it is necessary to repeatedly provide educational opportunities in an environment similar to actual clinical practice by developing various scenarios and introducing simulations and web-based formats.

Purpose: Nurses are exposed to stressful circumstances during the COVID-19 outbreak, which increases their turnover intention. This study aimed to identify predictive factors of turnover intention among nurses during the COVID-19 outbreak. Methods: This study was a cross-sectional design using self-report questionnaires. A total of 164 nurses working at three hospitals participated voluntarily in the study. Questionnaires included nursing professionalism, job satisfaction, control belief and COVID-19 stress. Data were collected from February 1, 2021, to March 15, 2021. Data were analyzed with SPSS WIN 23.0 program using descriptive statistics, x2-test, independent t-test and logistic regression. Results: The turnover intention rate of nurses was 33.5%. Two significant predictors of nurses' turnover intention were identified, including risk acceptance in caring for patients with COVID-19 (odds ratio [OR] 4.24, 95% confidence interval [CI]=1.76~10.49) and nursing professionalism (OR=1.06, 95% CI=1.02~1.10). Conclusion: Hospital administrations should provide an improved work environment, such as individual protective equipment, compensation and protective system to nurses to avoid turnover intention in COVID-19 outbreak.

Purpose: This study was conducted to explore male nurses' experiences of gender discrimination at the workplace using qualitative research methods. Methods: Participants responded to a survey using an online link, and were asked to describe their overall experiences by responding to the question "Please freely describe your experiences of workplace gender discrimination". The qualitative data collected from 118 participants were analyzed using Krippendorff's technique. Data collection was caried out from June 11, 2019, to August 3, 2020. Results: Eleven themes and 24 subthemes were extracted from a total of 277 meaningful statements. Male nurses' experiences of workplace gender discrimination, reasons of gender discrimination, and improvement strategies were presented through the key themes. Conclusion: Male nurses experienced workplace gender discrimination from patients, colleagues, and institutions. Furthermore, strategies to improve gender stereotypes and to emphasize the strengths of male nurses are necessary in order to increase the number of male nurses in the female-dominant nursing field and to reduce job turnover. These strategies will help expand the social role of nurses as professionals and improve the work environment and benefits for all nurses.
