오늘날의 대부분 의료기관이 성취해야 할 가장 중요한 과제는 의료 관리비용의 절감과 의료 서비스품질의 향상이다. 최근 병원의 대형화 및 병원간의 경쟁 과다로 인하여 환자에 대한 서비스는 호전되었지만, 병원 자체 인력에 대한 효율적 배분 및 인력 운용에 있어서의 형평성 문제는 아직까지 해결되지 못한 부분이 많다. 특히 모든 일을 경제 원리로 풀려고 하는 사회적 풍토 및 현대화, 대형화에 따른 병원 재정의 압박은 병원 운용 인력의 $30{\sim}40\%$를 차지하는 간호 인력에 대한 관심을 소홀히 하고 있다. 이에 본 연구에서는 국내 대형 병원을 사례기관으로 선정하여 기존의 간호사 근무 편성 기준을 분석하고, 이를 토대로 간호사들의 요일별, 시간별 선호도를 고려한 근무 편성표를 작성하여 간호사 근무에 형평성을 기하고자 한다. 또한 기존 휴리스틱에 의거한 근무표와 수리계획법을 활용하여 작성한 근무표 간의 비교를 통하여, 간호사 개인이 특정 근무 기간동안 얻게 되는 만족도를 분석하고자 한다.

This paper is concerned with air traffic controllers' fatigue and stress that they experience during their daily job particularly as being shift workers. Previous researches reveal that the controllers' fatigue and stress increase by several factors including time spent at work, traffic intensity, visibility, etc. The researches also indicate that air traffic controllers' fatigue and stress can be reasonably surrogated by their heart rate. We set three hypotheses relating the influencing factors and the fatigue and stress represented by the heart rates. Using wrist bands, air traffic controllers' heart rates at various situations are collected at Choongju airport. The hypothetical tests explicitly confirm that the heart rate is highly correlated with the traffic level and the time spent at work. In particular, it be shown that even when handling the same traffic level, air traffic controllers' stress level increases as the time they spent at work increases.

The community health practitioners (CHP) play an important role in primary health care services to the underserved population in rural area. Time and motion study of 26 CHPs in Kyungpook Province was conducted through work diary method for 6 consecutive days from the time they arrived until they left the primary health post(PHP) during the past 3 weeks from November 16 to December 5, 1987. The allocation of activity time by working category, service category, location of activity and CHP's function was analyzed according to the characteristics of CHPs i. e., age, marital status and experience as CHP. The major findings are as follows : The mean activity time per CHP in a week was 2,918 minutes. The length of their working hours was longer for older, married and more experienced CHPs than others. About 80% of the CHP's activities took place within the PHP and only about 20% occured outside of the PHP. Working hours for the outdoor activities were longer for younger, single and less experienced CHPs than others. The allocation of activity time by working category showed 46.3% in the technical work and 18.7% in the administrative work. Working hours for the technical activities were longer for younger, single and less experienced CHPs than others. The percentage of activity time revealed greatest as much as 63.1% for direct patient care in technical work and 61.6% for record keeping in administrative work. Of the total working hours in a week, direct patient care and public health activities accounted for 29.2% and 16.2%, respectively. Of the indoor activities, working hours for direct patient care were longer than those for public health activities. However, of the outdoor activities, working hours for public health activities were longer than those for direct patient care. The allocation of activity time by CHP's function showed 49.7% in management of common disease, 31.8% in management of PHP and technical supervision of village health workers, 9.5% in MCH and family planning, 6.6% in community health management and 2.4% in community approach. Based on these findings, it was found that CHPs were mainly working in the PHP with a majority of their time being spent for direct patient care rather than preventive and promotive health cares. To enhance the preventive and promotive health services of the CHPs and to involve the activities for community development, refresher course for CHPs should be reinforced and supervision mechanism of the CHPs should be established and operated in Gun- and province-level.

The study was conducted to identify the perception of patient-safety and the level of safety care activity among nurses in small-medium sized general hospitals. Data were collected at three hospitals among 344 nurses on April 2012 and administered questionnaire regarding the perception of patient-safety and safety-care-activity. Data analyzed by using descriptive statistics, inferential statistics was used to determine comparison, correlation and association (Pearson correlation, t-test, ANOVA, Scheffe test, multiple regression). The results revealed that there were significant differences in the level of perception of patient-safety according to the nurses' career, time of work, and work department in their hospitals. And also there were significant differences in the level of safety-care-activity according to the nurses' age, position, marriage, the nurses' career, time of work in their hospitals. Nurses with higher perceived level of patient-safety performed more safety-care-activities. The findings of the study suggests that in order to improve the nurse's perceived level of patient-safety and safety-careactivities, the hospitals need to establish the policies that support patient-safety, improvement the environmental system, proper working atmosphere to ensure appropriate work time, regulation nurse-patient ratio are also required.

Today, with the development of information technology, hospitals are actively researching hospital information systems that are not limited by time and space to integrate mobile computing technology into the medical field to manage the bulk data of medical information. Nevertheless, most hospitals still spend a lot of time and effort creating manual schedules. In this paper, we studied an optimization model for organizing nurses' shift work and constructed an automated nurse-type job organization system. For nurses working in S hospital, information data, requirements and constraints of nurses were constructed. By applying this, we proposed an optimized scheduling method and built a web-based platform used by head nurses and a mobile app platform used by general nurses to enable real-time interchange and sharing around web servers. Therefore, through the developed nurse needs type automated system, the head nurses will increase the convenience of the nurses to organize the work every month, and general nurses will help them to work more accurately through personal schedule management. It is also expected to increase work efficiency by sharing work schedules among nurses.
