Objectives : Shift work has been known to cause various health problems by making it difficult for humans to adapt to their natural circadian rhythms. In particular, shift workers tend to complain of sleep difficulties associated with work schedules, and sometimes use alcohol as a self-medication to induce sleep. To date, no clear mechanism has been identified regarding the link between shift work and sleep, between shift work and drinking. This study aims to confirm the relationship between shift work and sleep, and to analyze whether the change in sleep caused by shift work causes drinking. Methods : This study included 11360 people (5704 men and 5656 women) among the Korean National Health and Nutrition Survey data in 2014, 2016 and 2018. The work type between 6am-6pm was defined as day work, and other work types were defined as shift work. Using logistic regression analysis, the relationship between shift work and sleep quality, shift work and high risk drinking, drinking amount at 1 time, drinking frequency were analyzed. In addition, we analyzed whether sleep mediates the relationship between shift work and drinking using mediated analysis. Results : Shift work showed a significant negative relationship with sleep quality in men and women (male OR=1.37, 95% CI 1.11-1.70, female OR=1.26, 95% CI=1.05-1.50). There was no significant relationship between shift work and alcohol in the case of men, but in the case of women, there was a significant positive relationship between shift work and the number of alcohol consumption (OR=1.34, 95% CI=1.04-1.72). When mediation analysis was conducted, it was found that women's sleep quality partially mediated the relationship between shift work and the frequency of drinking. Conclusions : The results of this study suggest that shift work causes sleep difficulties, and in the case of women, drinking can be induced through the partial mediating effect of sleep. Considering that women are more likely to choose drinking as a coping method for sleep problems, more active interventions for female shift workers are needed.

해상교통관제 업무는 선박사고 발생 위험에 대한 부담감 및 교대근무 등 불규칙한 근무형태로 인해 스트레스가 많은 직종이다. 특히나 관제 업무는 고도의 주의와 예측능력을 요구하는 업무로 이를 저해하는 인적요인 분석 및 관리 필요성이 절실한 분야지만 관제사의 직무스트레스에 관한 연구가 전무한 실정이다. 관제사의 스트레스로 인한 피로증상은 관제업무수행에 필요한 인지능력이나 의사결정 능력을 저하시킬 수 있고 이로 인해 업무수행에 차질을 빚을 경우 안전사고로 이어질 수 있는 위험이 존재한다. 그러므로 안전과 직결된 관제사의 스트레스는 과학적으로 연구되어야 하며 제도적 마련과 더불어 체계적 관리가 필요할 것이다. 이에 본 연구에서는 한국인 직무스트레스 측정도구를 이용하여 관제사의 직무 스트레스 수준을 파악하고 직무스트레스 관리의 필요성에 대하여 제고해보고자 한다.

세계적으로 선박 교통량 증가와 함께 선박 사고 원인의 90% 이상을 차지하는 인적요인에 대한 심층적인 연구의 필요성이 대두되고 있다. 해상교통관제 업무는 고도의 주의와 예측능력을 요구하며 이를 저해하는 인적요인 분석 및 관리 필요성이 절실한 분야이다. 특히 관제업무는 교대근무 등의 불규칙한 근무형태로 인해 발생되는 피로와 업무 집중력 저하, 스트레스가 많은 업무이다. 무엇보다 관제 업무는 해상안전에 핵심적인 역할을 하는데, 관제사의 피로와 스트레스로 인한 업무 차질은 자칫 안전사고로까지 이어질 수 있는 위험이 존재한다. 이렇듯 인적요인이 중요한 영역임에도 불구하고 관제사들의 체계적인 스트레스 관리에 대한 방안은 미비한 실정이다. 본 연구에서는 직무스트레스 유발요인, 유발결과 및 설문조사를 통하여 관제사들의 직무스트레스 현 실태를 파악하고자 한다. 그리고 연구결과를 바탕으로 관제사의 피로, 스트레스를 관리하기 위한 방안과 더 나아가 효율적인 인적요인 안전관리 방안을 모색하고자 한다.

코로나19 확산으로 기업들이 재택근무와 화상회의 등을 시행하며 업무방식이 획기적으로 변화되고 있다. 재택근무를 시행한 직원들은 편하고 쾌적하다는 의견이 다수였지만, 일부 불편함을 호소하기도 했다. 일부 기업은 재택근무 형태가 긍정적이라고 보고 적극 도입을 검토하기 시작했다. 재택근무의 여러 장점 이면에는 스마트폰, 태블릿 등 스마트 기기의 사용 증가로 보안문제점이 심각하게 대두되고 있고, 스마트워크 환경은 클라우드 기반의 실시간 서비스가 그 생태계를 주도하고 있다. 따라서 이 같은 스마트워크 환경에 따른 법제화와 인사시스템 적용, 그리고 정보보호 및 보안 관련 인증을 통한 스마트워크 서비스의 개선이 절실히 필요하다. 본 논문은 기존 글로벌 시스템의 확산에 대응하기 위해 국내 시스템의 낮은 인지도와 품질 문제 해결을 위한 차세대 기술 개발 및 사용성 강화를 제안한다.

Purpose: This study was conducted to provide baseline data to develop work patterns for nurses that are suitable to Korean hospitals. Shift work patterns and nurses' preferences for working condition were examined. Methods: Questionnaires for nurse departments and nurses were mailed to 478 hospitals from June 1 to July 30, 2012. Nurse departments of 174 hospitals and 1,409 nurses responded to the questionnaire. Data were analyzed using SPSS statistical program. Results: Of the nurses, 89.4% were working three shifts. Of the hospitals, 17.3% had implemented fixed night work. Although 80% of nurses preferred fixed time work, only 24.9% of hospitals had fixed working hours. Of the nurses, 57% agreed with night work as fixed but potential night nurses accounted for only 17% of the respondents. Sixty-three percent of the nurses agreed on short time work during busy hours. There were preference differences according to age, marital status and clinical career. Conclusion: As many nurses reported a preference for various flexible working patterns rather than three shift work, there is a need for new decisions on hospital policy to ensure improved working conditions for nurses and enhanced job security. Legal requirements also need to be considered for various work patterns.

The purpose of this study was to examine the causes of career interruptions among dental hygienists, institutional measures required for their long service and ways of creating a stable employment culture for them in determine how to resolve labor shortage, create stable jobs, and step up the reemployment of idle manpower. In addition, the following suggestions are made for the establishment of a stable employment culture for dental hygienists by analyzing related literature, research materials, and information such as forums for establishing appropriate jobs for female dental workers. First, a system should be set up to prevent career interruption among dental hygienists. The work environment should be improved to prevent career breaks, and the wages, working hours, and working style should be efficiently structured to maintain the tenure of employees. Second, a plan should be devised to make use of idle manpower, and a variety of necessary programs should be developed. With respect to regular working hours, the time conversion system should be used, which reduces the amount of time one would want to work while receiving a national subsidy. Third, dental hygienists working in different occupations for marriage, childbirth, childcare, school and personal hygiene should make a way to return to the dental system immediately when they want. Fourth, the government should take institutional measures and offer down-to-earth support and benefits for women consideration their social characteristics to guarantee a balance between work and childcare.

This study was conducted to compare nurses' job stress, hardness and burnout between general hospitals and advanced general hospitals. Data were obtained through structured questionnaires from 394 nurses(general 198, upgrade general 196) in the C and S city between April and May, 2010. Data analysis was done with independent t test, ANCOVA, ANOVA, Scheffe & Eacute test and Pearson correlation coefficient with SPSS WIN v 17.0. Job stress, hardness, and burnout of nurses in general hospitals were 2.45, 2.11 and 3.70 respectively. Those in advanced general hospitals were 2.69, 2.70 and 3.70 respectively. Job stress and hardness were significantly higher in general hospitals. There was no significant difference of burnout between general and advanced general hospitals. Burnout of nurses in both hospitals was positively correlated with job stress and negatively correlated with hardness. Further studies are necessary for identify factors influencing job stress of general hospitals. Program for enhancing hardness of nurses in upgrade general hospitals should be developed.

This study was conducted to investigate the effects of trust in supervisor, work intensity, and organizational cynicism on organizational silence of clinical nurses. Data were collected from 134 nurses in 6 hospitals in two cities in February 2018. The data were analyzed by t-test, one-way ANOVA, $Scheff{\acute{e}}$ test, Pearson's correlation coefficient, and stepwise multiple regression using SPSS 25.0. There were significant correlations between trust in supervisor, work intensity and organizational silence, r=-.32(p=<.001) and r=.18(p=.043), respectively. The factors that significantly influenced organizational silence were trust in supervisor (${\beta}=-.36$, p<.001), the length of career in current hospital (over 10 years, ${\beta}=-.67$, p=.002), type of work (day only, ${\beta}=-.79$, p<.001; 3-shift, ${\beta}=-.64$, p<.001). In order to reduce clinical nurses' organizational silence, programs should be provided to increase trust in supervisor and to offer changes in work types and work intensity.
