본 논문에서는 Cactus와 Globus 기반의 그리드 컴퓨팅 환경에서 응용프로그램 수준의 체크 포인팅을 사용한 동적 재구성(Dynamic Reconfiguration) 기법을 새로이 제안하였다. 기존의 동적 재구성은 특정 하드웨어와 운영체제에 종속적이었으나 제안한 방법은 특정 하드웨어와 운영체제의 지원 없이 동적재구성이 가능하고 응용프로그램도 동적 재구성을 고려할 필요 없이 프로그래밍이 가능하다. 제안한 동적 재구성 기법에서 초기 연산자원의 구성을 갖고 실행되는 작업은 실행 중에 동적으로 발견된 새로운 연산자원을 포함하여 계속 연산을 수행한다. 본 연구에서 제안된 방법은 새롭게 발견된 연산자원의 프로세서 성능과 유휴 메모리를 고려하여, 해당 연산자원을 수행중인 연산에 포함할 것인가 여부를 결정한다 연산중 연산 결과의 실시간 가시화를 가능하도록 하고 운영체제에 종속적이지 않은 응용프로그램 수준의 체크 포인팅 기법을 사용하여 중간 연산결과를 저장한다. 새롭게 발견된 유휴사이트, 유휴프로세서를 포함하도록 연산자원의 구성을 재구성한 후 체크 포인팅 파일을 사용하여 작업을 계속 실행한다. 제안한 동적 재구성 기법은 K*Grid 환경에서 연산시간을 단축함을 확인하였다.

This study is concerned with a job sequencing method using the concept of sampling technique. This sampling technique has never been applied to develop the scheduling algorithms. The most job sequencing algorithms have been developed to determine the best or good solution under the special conditions. Thus, it is not only very difficult, but also taken too much time to develop the appropriate job schedules that satisfy the complex work conditions. The application areas of these algorithms are also very narrow. Under these circumstances it is very desirable to develop a simple job sequencing method which can produce the good solution with the short tine period under any complex work conditions. It is called a sampling job sequencing method in this study. This study is to examine the selection of the good job sequence of 1%-5% upper group by the sampling method. The result shows that there is the set of 0.5%-5% job sequence group which has to same amount of performance measure with the optimal job sequence in the case of experiment of 2/n/F/F max. This indicates that the sampling job sequencing method is a useful job sequencing method to find the optimal or good job sequence with a little effort and time consuming. The results of ANOVA show that the two factors, number of jobs and the range of processing time are the significant factors for determining the job sequence at $\alpha$=0.01. This study is extended to 3 machines to machines job shop problems further.

본 연구는 정확한 중소기업 일자리 정보를 알지 못하는 상황, 선호 기준에 맞는 일자리 파악이 어려운 현실을 브랜드 범주화 이론을 반영한 '고용주 브랜드(Employer Brand)' 관점에서 개선하고자 하였다 이를 위해 청년구직자 700명을 대상으로 위계적 회귀분석을 통해 5가지 가치 요인(Interest Value, Social Value, Economic Value, Development Value and Application Value) 중심의 취업의향 영향요인을 파악하였다. 분석결과 청년구직자는 인재육성이나 제품, 서비스, 경영진 등 기업 측면의 특성보다 구직자 개인에게 직접적 영향을 미치는 업무문화와 환경, 자신의 전공 활용 등에 보다 관심을 가지고 취업의향에 영향을 받는다는 것을 확인하였다. 이는 중소기업 일자리 정책이 기존 양적 지원 중심에서 플랫폼 중심의 일자리 정보 활용을 강화하는 질적 체질 개선으로 변화될 필요가 있음을 시사하고 있다.

의료기관 내 진료실에서 성희롱 문제 해결을 위해 샤프롱 제도를 적용하고 있다. 이에 방사선 업무 특성을 고려하여 방사선 업무에서의 샤프롱 제도 적용을 고려하여 방사선사들의 샤프롱 제도 적용의 요구도와 직무에서 발생할 수 있는 영향을 분석하고자 한다. 2021년 말부터 2022년 초까지 대구 경북지역 방사선사를 대상으로 설문조사를 하였으며, 약 52.9%의 회수된 설문을 통해 분석하였다. 분석 결과 샤프롱 제도 적용을 요구하는 경우는 남성보다는 여성이, 연령이 낮을수록, 학위 수준이 높을수록, 그리고 연차가 낮을수록 높았다. 그리고 샤프롱 제도의 적용에 따른 직무 영향은 요구도가 높을수록 성희롱 감소 및 신뢰도는 향상되지만 직무의 효율성, 전문성, 편의성, 소속감 및 복지는 부정적으로 변화될 것으로 생각하고 있다. 즉, 낮은 연령 및 학식이 높아질수록 샤프롱 제도의 필요성이 높지만 적용하기 전 직무의 보장 및 고용의 안정성을 정책적으로 보완하여야 할 필요가 있다고 생각하고 있다는 것이다. 따라서 향후 방사선 업무에서 샤프롱 제도의 적용을 고려한다면 해당 직종의 직무 보장을 위한 사전 의견 수렴을 충분히 수행할 필요가 있을 것으로 판단된다.

Objective: The aim of this study is to investigate the job rotation implementation at medium- or small-industries and to identify the viewpoint on job rotation as preventive activity of work-related musculoskeletal disorders(WMSDs). Background: Job rotation has been implemented in many industrial areas in order to prevent the WMSDs as one part of ergonomic program. Generally, the cases of implementation of ergonomic program or successful cases of job rotation were reported on the side of major or large company. Therefore, this study tried to inspect the current state of job rotation implementation at medium- or small-industries. Method: Survey was carried out for randomly contacted forty seven mangers responsible for safety. Survey contained the questionnaires on the general state of company, shift-work and job rotation. Results: The ratio of work-shift in medium- and small-industry was 34.0% and the ratio of job rotation was 19.1%. For manufacturing industry, the ratio was 37.9% and 17.2%, respectively. Conclusion: The implementation ratio of job rotation was relatively low considering the results of previous studies. Many managers appealed the quality decreasing of goods and the injuries of workers due to job rotation, though agreed to train the multi-functional worker and to prevent the WMSDs. Application: The results can be used for the fundamental data how the job rotation will be properly implemented in medium- and small-industry as an administrative control for MSDs.

Objective: The aim of this study is to review the job stress measurement for applying in nuclear power plants(NPPs). Background: The standard and guideline to evaluate and manage the job stress is insufficient in NPPs. Although job stress might have a negative effect on task performance particularly it can be related with human error in NPPs. Method/Results: This paper considered the objective and subjective stress measurements. One of the questionnaire(Korean Occupational Stress Scale) and the experiment method was investigated to apply in NPPs. KOSS was analyzed about the inter item consistency and correlation with the workload, and relative importance. In the objective evaluation considered the experiment method for the physical and mental job stress and analyzed from the phased point of view. Conclusion/Application: The measurement and criteria to evaluate job stress for operators must be complemented on the job characters and environments in NPPs. This study may support to confirm and manage the job stress in NPPs. The study of more specific methodology on job stress in NPPs is required on the basis of this paper.

Purpose: The purpose of this study was to examine the relationship of psychosocial wellbeing status and self leadership with job satisfaction of fire officers. The effects of these variables on job satisfaction were also examined. Methods: The study design was a descriptive, correlational design. For this study, data were collected from 189 fire officers in B metropolitan city, K and Y cities. Data were analyzed using descriptive statistics, t-test, one-way ANOVA, and multiple regression analysis with SPSS 21.0 program. Results: The results showed that job satisfaction had a significant correlation with psychosocial wellbeing status (r=-.38, p<.001) and self leadership (r=.26, p<.001). Psychosocial wellbeing status had a significant correlation with self leadership(r=-.47, p<.001). Multiple regression analysis for job satisfaction revealed that the most powerful predictor was psychosocial wellbeing status followed by self leadership. Pychosocial wellbeing status, self leadership, age, marital status and current job task career explained 25.0% of the variance in job satisfaction. Conclusion: Findings indicate that various factors are related to the job satisfaction of fire officers. Based on the results of this study, further development and application of programs to improve fire officers' job satisfaction are needed.
