Previous studies related to drinking problems among Korean employees has focused on not 'drinking on the job' but 'drinking off the job'. Thus, little is known about the relationships between 'drinking on the job' and work performance among employees in Korea. The purpose of this study is to examine the relationships between alcohol use including 'drinking on the job' and 'drinking off the job' and work performance among 577 employees working at the health or welfare related agencies in N-gu of Seoul. Analyses were conducted using univariate analyses and multiple regression to examine which alcohol use factors were associated with work performance among employees. As for alcohol use, 49.3% of participants reported 'drinking on the job' in the past 30 days and 48.2% of participants reported 'drinking in a company dinner' in the past 30 days. Univariate analyses on the relationships between alcohol use including 'drinking on the job' and 'drinking off the job' and 'work performance' showed' drinking on the job' was associated with all work performance items except 'being absent' and 'being hurted' were not associated with work performance. Meanwhile, 'drinking off the job' was related to only 'did not do the job well'. Multiple regression analyses demonstrated that gender, subjective health status, service period, and 'drinking on the job'. These findings suggested that there is a need to more concerns about 'drinking on the job', especially 'drinking in a company dinner' among employees in Korea.

Recently, interesting in flexible working has been increased, and some central government and large companies are conducting flexible working. With the conducting of flexible working, workers are able to get a convenience but the cost of managing is increased. In this paper, we suggest a method of reducing the cost and managing efficiently. Our study determines the position of the workers using indoor localization techniques through the Wi-Fi fingerprint and smartphone, and records the office hours. The previous time and attendance systems have to install attendance recording device(e.g. Fingerprint Attendance System, RFID Card Attendance System) and are needed to manipulate manually. Our system doesn't need to install extra devices, and also doesn't need to manipulate manually. Our system automatically records the office hours. Also most of previous time and attendance systems have another weakness. They only record data when workers start and stop work. But our system exactly records office hours for each workplaces. In this paper, We introduce an effective time and attendance system in variety flexible working. Our experiments shows that our system workers' detected office hours accurately. The accuracy of our time and attendance system was 98.7%.

현재 미국은 일일 8시간을 근무하면서 주당 연닷세 근무, 연이틀 휴무하는 근무제도를 통상 사용하고 있어서 이 제도에 대한 최적 휴일 할당 방법이 연구되어 왔다. 그러나 한국은 일일 8시간을 근무하면서 주당 연닷세반 근무, 하루반 휴무제도를 통상 사용하고 있다. 본 연구는 근무업무( service )에 있어서 한국적 휴무제도에 적용될 수 있는 휴무할당 방법을 토의한다. LP기법 및 수식의 도움이 없는 간단한 계산방법이 최적휴무할당을 위하여 사용된다. 이들 방법은 노동소요를 충족하면서 고용인의 유휴 노동기간을 최소로 하는 최적휴무 할당방법임을 토의한다.

Since government institutions begin working 40 hours each week, public libraries in Korea face the challenge of not only enhancing the quality of life for librarians by improving their work environment, but also providing adequate information services for patrons. The purpose of this study is to examine the potential problems which could happen with the 40 working-hours each week in public libraries, and establish the strategies for resolving these problems. For this study, based on the existing research, an attempt is made to review and analyze the following facts: (1) the details of planning for 40 working-hours each week at the government institutions in Korea; (2) the current work environment and service strategies of public libraries in other countries, including the U.S., where librarians work 40 hours each week; (3) the present state of managing public libraries with 40 working-hours each week in Korea; and (4) the strategies of public libraries as a part of cultural infrastructure in preparing for 40 working-hours each week which will be fully implemented at the government institutions in Korea.

최근 병원행정가들의 가장 관심을 끄는 분야 중 하나가 간호사의 이직이다. 본 연구는 실제 이직을 한 간호사를 대상으로 이직요인을 파악하고 이에 대한 이직대책을 제시함으로써 조기에 간호사의 이직을 예방하여 효율적으로 간호인력을 관리하고 간호의 질적 향상을 하는데 도움을 주고자 46개 종합병원에서 1998년 1월${\sim}$1999년 1월 사이에 이직을 한 간호사 369명을 대상으로 조사, 분석한 후향연구이다. 연구결과를 통해 이직결정에는 다양한 요인들이 영향을 미침을 알 수 있었다. 특히 결혼상태가 가장 큰 요인으로 나타났으며, 기혼인 경우는 자식의 양육문제가 가장 원인이었으며, 미혼인 경우는 불규칙한 근무시간이 큰 영향을 미치고 있었다. 그에 대한 해결책으로 자식 양육문제의 경우, 근무병원 내에 탁아시설을 운영하거나 육아양육휴가제도 및 시간제 근무 등의 도입을 심각하게 고려해 볼 필요가 있다. 불규칙한 근무시간은 근무외 수당을 지불하거나 간호사가 스스로 자신의 근무시간을 선택할 수 있는 융통성 있는 스케줄링, 또는 승진평가 제도를 적절하게 할 수 있는 제도의 도입을 제안한다.

This paper presents a prescriptive alternative for establishing a FRMS suitable for us based on scientific data ahead of the introduction and implementation of the FRMS for air traffic controllers in order to meet the International Civil Aviation Organization (ICAO) international standards. I would like to present. Therefore, we confirmed the operation of each air traffic control agency against the current domestic operating standards, and compared and reviewed the operation methods and standards of air traffic control agencies in each country. The controller in Korea defines 10 hours of working hours per day, 8 hours of minimum breaks, and 40 hours per week. Currently, in the case of air traffic control agencies, the daytime and the appropriate working hours are used in the daytime, but in the nighttime, the average time exceeds 5.9 hours. In the case of 40 hours a week, they work an average of 15.7 hours overtime. By adjusting the nighttime work time, this work can be solved by diversifying the form of the worker's input method according to the personal schedule rather than the two-day (day / night) method, as well as the appropriate nighttime time distribution by supplementing the personnel.

The 40-hour work week system has brought positive impact on shortening working hours, eliminating long-time work, increasing leisure-time with family, etc. And this has brought about an increase in leisure-life satisfaction and happiness level. The type of leisure activities has changed from passive activities such as rest to active activities such as sports, tourism. And the 40-hour work week system has positive impact on social activities such as participation in volunteer work and, club activities. Thus all efforts need to be made to establish 40-hour work week system as soon as possible in all workplace. Firstly, 40-hour work week system needs to be introduced to every workplace with less than 5 persons, enlarge 5-day school week system into every primary and secondary school, and create conditions for positive leisure activities. Secondly, labor standards supervision and administration needs to be strengthened to eliminate long-time work over 52 hours per week, below-minimum wage work.
