This study is a measurement of effectiveness to a job process for the hospital information system (HIS) used in the hospital industry. Using the effectiveness scale that I developed in the questionnaire of the ISO9241-11 quality model, I measured the importance level of HIS and its significance on a job practices in the large general hospitals within the country. The questionnaire showed that the importance level of domestic HISs was highest in the system used by staffs(mean=3) and to reduce a job process and increase the efficiency of work.

When a competent employee leaves an organization, the technical skills and know-how possessed by that employee also disappear, which may lead to various problems, such as a decrease in organizational morale and technology leakage. To address such problems, it is important to increase employees' job satisfaction. Due to the advancement of both information and communication technology and social media, many former and current employees share information regarding companies in which they have worked or for which they currently work via job portal websites. In this study, a web crawl was used to collect reviews and job satisfaction ratings written by all and incumbent employees working in nine industries from Job Planet, a Korean job portal site. According to this analysis, regardless of the industry in question, organizational culture, welfare support, work system, growth capability and relationships had significant positive effects on job satisfaction, while time and attendance management, performance management, and organizational flexibility had significant negative effects on job satisfaction. With respect to the path difference between former and current employees, time and attendance management and organizational flexibility have greater negative effects on job satisfaction for current employees than for former employees. On the other hand, organizational culture, work system, and relationships had greater positive effects for current employees than for former employees.

In this paper, we propose an efficient dynamic workload balancing strategy which improves the performance of high-performance computing system. The key idea of this dynamic workload balancing strategy is to minimize execution time of each job and to maximize the system throughput by effectively using system resource such as CPU, memory. Also, this strategy dynamically allocates job by considering demanded memory size of executing job and workload status of each node. If an overload node occurs due to allocated job, the proposed scheme migrates job, executing in overload nodes, to another free nodes and reduces the waiting time and execution time of job by balancing workload of each node. Through simulation, we show that the proposed dynamic workload balancing strategy based on CPU, memory improves the performance of high-performance computing system compared to previous strategies.

In this paper, we analyzed the relationship between employment stability, wage level, welfare system, working condition, job satisfaction and organizational commitment in order to find out ways to develop and competitiveness of the nano-convergence industries. Through this study, we conducted the possibility of deriving organizational commitment by job satisfaction which is given through employment stability, wage level, welfare system, and working condition for continuing their work life. In order to find relationships between each concepts, we used a multiple regression analysis with job satisfaction and commitment as dependent variable and employment stability, wage level, welfare system, and working condition as independent variables. Through this study, it was expected to increase the organizational commitment through the job satisfaction of the employees if a changing method of employees management is centered on some tasks suggested for the sound working condition and efficient utilization policies.

The purpose of this study was to investigate user satisfaction at Defense Medical Information System as it has been utilized as a part of National Defense Information Strategies since Aug. 2000. The subjects of this study were nurse officers and army surgeons of a hospital with 1,000 beds. The results of this study are as follows; First, according to the characteristics of the subjects, there was statistically significant difference in system satisfaction, job satisfaction and information satisfaction at Military Hospital Information System. Second, according to the intention of participation, there was a statistically significant difference in user satisfaction at Military Hospital Information System. Third, according to a level of dexterity at Military Hospital Information System, there was statistically significant difference only in job satisfaction. Fourth, factors to influence system satisfaction were one's duty, using period of Military Hospital Information System, and a level of dexterity at Military Hospital Information System. Factors to influence job satisfaction were a level of dexterity at Military Hospital Information System, one's duty and intention of participation. Factors to influence information satisfaction were one's duty, a level of dexterity at Military Hospital Information System, and intention of participation. As the first study on user satisfaction at Military Hospital Information System, this study suggests the followings. First, a plan to inspire users with intention of participating in information system should be prepared. Second, it is necessary to provide policy activities for job standardization of Military Hospital Information System and legal system improvement.

This paper designed and developed internet based competency developing system for small IT (Information & Technology) companies. The purpose of this system was to provide career development opportunities to small IT business workers for their longstanding employment and self-improvement job skills. This study analyzed job competencies based on job descriptions from two IT companies. The survey was conducted to analyze employees' self-assessed current job competency level and effective ways of improving their current level of competencies. From the results of survey, most of subjects indicated their job competencies were in between mid-level to low level, and they required the need of training programs to improve their job knowledge and experience. Based on the interview from field experts about job competency development, this study designed and developed the internet based competency development system to provide effective and efficient way of improving job competencies and needed training programs for small IT business employees.

Purpose: This study was conducted to identify the level of job stress and to determine factors influencing job stress among nurses currently under Academic Credit Bank (ACB) system. Methods: The participants were 153 nurses who has taken courses of ACB system. Data were collected through self-report questionnaires and then analyzed with t-test, ANOVA, Pearson correlation coefficients, and multiple linear regression with SPSS/WIN 18.0. Results: The score of job stress showed significant differences according to age, marital status, total period of clinical career, and nursing unit. Job stress had significant negative correlation to professional self-concept and organizational commitment. The factors influencing job stress were marital status, professional self-concept, and organizational commitment. Conclusion: The results suggest that various factors should be considered in development and implementation of programs to reduce the job stress of nurses currently under ACB system.

저출산 및 인구 고령화가 가속화되면서, 중장년 퇴직자 등 노동 소외 계층의 취업난 해결은 우리 사회의 핵심 과제로 등장하고 있다. 온라인에는 수많은 일자리 요구 정보가 산재해 있으나, 이를 중장년 구직자에게 제대로 매칭시키지는 못하고 있다. 워크넷 취업 로그에 따르면 구직자가 선호하는 직종에 취업하는 경우는 약 24%에 불과하다. 그러므로, 이러한 문제를 극복하기 위해서는 구직자에게 일자리 정보를 매칭시킬 때 선호하는 직종과 유사한 직종들을 추천하는 소프트 매칭 기법이 필수적이다. 본 연구는 중장년층에 특화된 소프트 직업 매칭 알고리즘과 서비스를 고안하고 개발하여 제공하는 것을 목표로 한다. 이를 위하여 본 연구에서는 1) 대용량의 구직 활동 기록인 워크넷 로그로부터 중장년층의 일자리 특성 및 요구 추세를 분석하였다. 2) 중장년층의 일자리 추천을 위해 직종 유사도 기준으로 일자리 분류표(KOCM)를 재정렬하였다. 이 결과를 이용하여, 3) 중장년에 특화된 인력 고용 소프트 매칭 직업 추천 알고리즘(MOMA)을 개발하여 구인 구직 웹사이트에 적용하였다. 자체 저작한 중장년층 특화 일자리 분류표(KOCM)를 이용한 소프트 일자리 매칭 시스템의 정확도를 측정하였을 때, 실제 고용 결과 기준, 하드 매칭 대비 약 20여 배의 성능 향상을 보였다. 본 연구내용을 적용하여 개발한 중장년층 특화 구직 사이트는 중장년층의 구직 과정에서 입력 정보 부담을 최소화하고 소프트 매칭을 통해 사용자의 요구직종에 적합한 일자리를 정확하고 폭넓게 추천함으로 중장년층의 삶의 질 향상에 기여할 수 있을 것으로 기대된다.
