코로나19 팬데믹으로 사회적 거리 두기가 확산됨에 따라 원격근무가 확산되면서 정부기관에서도 지난 3월부터 재택근무가 시작되어 현재도 일정 수준을 유지하고 있다. 따라서 비대면 시대의 원격근무 본격적인 확산에 대비해, 정보시스템 성공모형과 기술수용모형을 기반으로 정부기관에서 재택근무 시 필수적으로 사용하고 있는 정부원격근무서비스인 Government Virtual Private Network의 품질요인이 이용자 만족도에 미치는 영향 등을 분석하여 개선방안 마련에 기여하고자 한다.

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.

The munber of private guard on which this study has been conducted in 200, who work at large conmpanies, medium or small companies and the like as located in Seoul and kyonggi. In this study blood lactate, phosphorus and ammonia were measred to see the level of fatigue. There was significant difference in blood lactate, phosphorus ammonia and fatigue between working hours(P<0.05). in view of the results of this study, it can be thought that fatigue is more affected by working hours In summary, these results are interpreted to mean that 1) fatigue levels and blood fatigue induced factor (lactate, phosphorus, ammonia) increase due to a rise in working hours.

Until now, research related to telecommuting has been mainly conducted in information and communication fields such as smart work, and the need for this study emerges in that there are insufficient cases or studies confirming visible job productivity or organizational performance for companies to grasp. The purpose of this study is to investigate how telecommuting affects job performance through job creativity and job satisfaction of members of the organization. As a result of the analysis, it was found that the perception of telecommuting characteristics (communication collaboration, job productivity, work-life balance) had a significant positive (+) effect on both job creativity and job satisfaction. Second, job creativity and job satisfaction were also found to have a positive effect on job performance. Based on the analysis results of this study, it is expected to provide usefulness evaluation indicators for telecommuting to managers and policymakers of companies or institutions that want to introduce and operate telecommuting in the future in the post-COVID-19 era.

The present study was designed to evaluate the effects of staff training in PBS on the behaviors of staff and children with developmental disabilities in an inpatient unit. The perceived significance of children's problem behavior and staff's caring stress significantly decreased with the intervention. A satisfaction survey reported staff's high satisfaction with the process and results of staff training. This study suggests that PBS is a socially valid and positive intervention with problem behavior of children with developmental disabilities. The implications and limitations of this study, with directions for future research, are also discussed.

Due to the COVID-19 pandemic, the global population has experienced drastic changes, one of which is the increase in remote work. Given the ongoing possibility of exposure to infectious diseases and various other circumstances, the expansion of remote work is anticipated. To enhance the efficiency of remote work and address its existing limitations, this study surveyed the perceptions of indoor environments among individuals who worked from home during the COVID-19 pandemic. The study examined how the characteristics of individuals influenced their perceptions of indoor environments. It was found that the number of occupants and rooms, size of the house, and noise sensitivity affected the perceptions of outdoor noise, neighbor noise, and indoor noise caused by cohabitants. The findings can be used as foundational data for designing multipurpose housing that can be utilized not only for residential purposes but also for work and educational settings in the future.

Recently, As ICT technology develops, cyber attacks are becoming more intelligent and advanced. In order to cope with such cyber attacks, the security control system must be maintained 24 hours a day, 365 days a year. Security personnel should be able to respond in real time to cyber attacks through shift work for 24 hours, but the workforce law was revised in 2018 to affect manpower and security control work systems. Therefore, in this paper, we propose an effective security control work system by reducing 52 working hours per week.
