Methods: Research participants were 130 nurses who worked in the customized home health care of 20 county in Gyeongnam province. Data collection for this descriptive correlational study was done at August 2010 using self report questionnaires, and analyzed using descriptive statistics, t-test, ANOVA, and we analyzed a four step approach in which several regression analyses were conducted and significance of the coefficients is examined at each step. Results: The results from step 1 showed that, the effect of each job stress was significantly related to job satisfaction. In step 2, the direct effect of commitment to organization on job satisfactions were all significant too. Step 3 analysis showed that the total effect of each job stress on commitment to organization symptoms was significant. Step 4 showed the results of controlling for mediating factor (job satisfaction): job demand and insecurity were significantly associated with commitment to organization(p<0.001), the finding supports that others were fully mediated by each job satisfaction, and, the job demand and insecurity were partially mediated by job satisfaction.

기존의 접근 제어 메커니즘인 강제적 접근 제어와 임의적 접근 제어는 무결성을 요구하는 상용 환경의 정보 보안에는 부족하여 이의 대안으로 직무 기반 접근 제어 (RBAC:Role Based Access Control)가 주목 받고 있으며, 직무를 수행하는 사용자의 의무 분리(Separation of Duty)에 대한 연구가 최근 이루어지고 있다. RBAC에서 사용자는 직무에 배정된 접근권한(Privilege) 만을 수행하여야 하는데 상호 배타적(Mutual exclusive)특성을 갖는 직무는 표현 및 접근 권한의 직무 배정과 수행에 있어서 어려움이 있다. 본 논문에서는 RBAC의 기본 특성을 분석하여 직무에 접근권한을 부여하고 사용자를 직무에 배정하는데 따른 안전한 접근 제어를 위하여 반순서 관계를 갖는 직무의 승계 속성에 따라 직무의 계층 형태를 분류하고, 직무에 배정되는 접근권한의 표현과 관리를 용이하게 하기 위하여 객체에 부여된 객체 접근권한을 분석하여 방향성 그래프를 이용하여 기본 접근권한으로 모델링한다. 접근권한 그래프(Privilege Graph)로 표현된 기본 접근권한에 직무를 배정하면 상호 배타적 직무의 접근권한과 의무 분리의 표현 및 관리를 용이하게 할 수 있다. 이를 기반으로 의무 분리를 포함한 RBAC의 안정성 특성과 접근권한 그래프를 이용한 직무의 의무 분리를 위한 직무 관리 알고리즘을 제시한다.

This study was conducted to compare and analyze occupational stress and satisfaction levels of the nurses in two different units to provide data for effective nursing resource management. Survey was conducted in four hospitals in June 2019 and data was obtained from 62 nurses in comprehensive nursing service units (CNSU) and 62 nurses in general units (GU). CNSU nurses had higher level of job satisfaction than GU nurses. Contributing factors included pay, professional status, administration, autonomy, task requirements, and interaction. Job stress level was not significantly different between groups. GU nurses had higher stress levels from nursing practice, conflict with doctors, and patients and caregivers, while CNSU nurses had higher stress levels in working condition. Negative correlation was found between job satisfaction and stress in GU nurses, whereas not in CNSU nurses. Clear definition of task, smaller work load, appropriate reward, and educational support is suggested to enhance job satisfaction.

Currently, in studying the relationship between POPs and burnout there is a lack of researches on certain settings and conditions. The present study examined a model in which relationship between POPs and burnout was mediated by psychological need satisfaction. And also, this study tested moderating role of psychological capital between POPs and need satisfaction. A total of 220 employees in telco and electronic manufacturing company in South Korea participated in this study. The result of this study showed that need satisfaction works as mediating variable between POPs and burnout and psychological capital had moderating effect between POPs and need satisfaction.

Universities or job training institutes need to develop training courses that match up with requirements of enterprises. Therefore, job analysis system that analyzes skills which are needed for job performing and makes it possible to be reflected in the curriculums is requested for deriving generalized curriculum system. In this paper, to develop a curriculum that fulfills the requirements of enterprises, we implemented a series of DACUM(Developing A CurriculUM) based process that performs verification of tasks for workers and roadmap for curriculum, etc. And, we analyzed a instance of this application system. The proposed system is implemented by Java and MS Access database. The system is possible to work with central database realized by MS SQL Server through the Internet.

This study was conducted to determine the relationship between the job stress levels of 669 subway operators in Seoul after the installation of screen doors and their mental health. Data were collected using a structured questionnaire and via web site. A multiple linear regression analysis was conducted using the SPSS 20.0 statistical program. The total score of job stress turned to be higher than the standard score, and physical environment, job demand, insufficient job autonomy, interpersonal conflict and occupational climate were within the top 50% and organizational system within the top 25%. A correlation analysis revealed that job stress was positively correlated with all sub-domains of mental health. In terms of effects of job stress on mental health, there were significant differences according to job demand, organizational system, lack of reward and occupational climate, with an explanatory power of 36.6%. It is expected that this study can provide foundation for the establishment of organizational measures accustomed to job characteristics to prevent job stress of subway operators and the development and implementation of intervention programs for mental health promotion.

The purpose of this study is to investigate the occupational stress of physical therapists. A total of 302 physical therapists participated in this study. All participants were responded to a Korean Occupational Stress Scale-short form to investigate occupational stress. We compared the occupational stress of physical therapists according to the gender, employee type, medical facility, and the department. Occupational stress showed a significant difference only in gender. Overall, the physical therapist showed low occupational stress in this study. However, among the 7 items on the Korean Occupational Stress Scale-short form, the 'Job demand' item score was higher than other items. This study suggests that the hospital administrator needs to provide proper job demand and environment considering the level of the physical therapists in order to effective occupational stress management.

Expenses in the form of personnel expenses in the past, in modern times, machine guards to gradually transition has been. This is because the machine guard is more efficient than personnel expenses. But due to false alarms, despite the high expectations of the effects of electronic security in the operation of the electronic security system due to factors that hinder the development of machine guards growth slows. Defect removal aspects of this paper, using IPA (Importance Performance Analysis) techniques to study the operation of electronic security systems and its importance in the development of machine guards, look at how high the technical aspects of electronic security systems composite type of malfunction to minimize crime sensor are presented.
