Despite decades of work experience, workers at small- and medium-sized enterprises(SME) here have yet to make inroads into the self-employed sector that utilizes the job competency they have accumulated at work after retirement. Unlike large companies, SME do not have a proper system for improving the long-term job competency of their employees as they focus on their immediate performance. It is necessary to analyse the independent variables affecting the job competency of employees of SME to derive practical implications for the personnel of SME. In the preceding studies, there are independent variable analyses that affect job competency in specialized industries, such as health care, public officials and IT, but the analysis of workers at SME is insufficient. This study set the person-job fit and organizational justice based on the prior studies of the independent variables that affect the job competency of SME general workers as a dependent variable. The sub-variables of each variable derived knowledge, skills, experience, and desire for person-job fit, and distribution, procedural and deployment justice for organizational justice, respectively. The survey of employees of SME in Korea was conducted from February to March 2019 by Likert 5 scales, and the survey was retrieved from 323 people and analyzed in a demonstration using the SPSS and AMOS statistics package. Among the four sub-independent variables of person-job fit, knowledge, skills and experience were shown to have a significant impact on the job competency, and desire was not shown to be so. Among the three sub-independent variables of organizational justice, deployment justice has a significant impact on job competency, but distribution and procedural justices have not. Personnel managers of SME need to improve the job competency of their employees by appropriately utilizing independent variables such as knowledge, skills, experience and deployment at each stage, including recruitment, deployment, and promotion. Future job competency modeling studies are needed to overcome the limitations of this study, which fails to objectively measure job competency.

여객선의 안전은 인명의 안전과 직결되므로 이에 발맞추어 국제해사기구 (International Maritime Organization, IMO)는 빈번히 발생하는 선박의 전복 사고로 인한 인명 피해를 최소화하기 위하여 승객탈출분석 (Passenger Evacuation Analysis) 적용 지침을 꾸준히 개정 및 보완하고 있다. 승객탈출분석의 목적은 설계 단계에서의 탈출 설비의 배치 적합성 판단 및 배치된 탈출 설비를 이용하여 지침 상 규정하는 최대허용탈출시간 (Maximum allowable evacuation duration) 내에 탈출이 가능한 지를 분석하는 것이다. 본 논문에서는 승객탈출분석에 관한 지침의 개정 동향 및 최근 개정된 승객탈출분석 지침 (MSC.1/Circ.1533)의 개정 방향에 대하여 소개하고자 한다. 또한 탈출 해석 관점 한국해양과학기술원에서 개발 중인 인명대피안내시스템의 유효성을 검증하기 위하여 2016년 10월 수행 된 인명대피실험과 지침 상 규정하는 고도화 알고리즘 (Advanced algorithm) 기반 승객탈출 시뮬레이션 (Maritime EXODUS)의 비교 결과를 바탕으로 해당 지침 적용 시 고려사항에 대하여 고찰하고자 한다.

This study is of academic significance to investigate the relationship between person-job fit and job-based psychological ownership, which previous studies lacked, and further confirmed for the first time in Korea that job-based psychological ownership mediates the relationship between person-job fit and job performance. In addition, the study supports the expectation theory that competency suitability affects job performance and the social exchange theory that requirement suitability affects job performance.

Existing human resources dispatch systems face various limits for managing increasing information derived from the work-place as it required much time managing the basic data created at the work-place and the data input methods are complicated. This study focuses on how to solve the above mentioned problems by utilizing the cellular phone system, which provides vital connection between the organizations using the dispatched human resources and the resources. The study offers building of a necessary work history data base and its management through development of a mobile human resources dispatch system. In order to optimally place the given resources, the system utilizes deductive analytical process. Utilizing the intelligent, deductive analytical process in properly planning the placing of the right human resources to do the job will result satisfaction in human resources dispatch and management.

본 논문은 폭넓은 전기환경 실증연구가 가능한 실규모 HVDC 시험선로의 설계 및 구축에 대해 소개한다. 국내 실정에 적합한 초고압 가공 직류송전(HVDC)선로 설계를 위해서는 전기적인 환경 장애를 일으키지 않는 환경친화적인 설계 및 건설에 대한 대안이 마련되어야 한다. HVDC 선로의 전기적인 환경영향은 주로 (+)극과 (-)극에서 발생하는 이온의 흐름에 의한 이온전류 밀도, 대전전압, 지표면전계강도 등 이온류(Ion流)의 영향과 초고압 송전에 따른 코로나 영향에 대해 검토하는 것이다. HVDC 실규모 시험선로는 요크, 특수 애자련, 특수 arm을 사용하여 철탑의 극간 배치, 도체 배치 변경 및 지상고 변경이 가능하도록 winch를 채용하여 절연설계 조건의 유동성, 환경, 지지물, 송전기자재, 경제성 및 운용의 효율성을 종합적으로 고려할 수 있도록 특수한 형태로 설계하여 각종 전기환경 실증연구가 가능하며 국내 환경 특성에 적합한 최적 극배치 좌표 도출이 가능하도록 구축되었다. 본 논문은 상용 가공 HVDC 송전방식의 적용에 앞서 현재의 상황을 고려한 전기환경 실증 연구가 가능한 실규모 HVDC 시험선로의 설계 및 구축에 대하여 기술하였다.

Regardless of which country, all public libraries need facilities, collections, and funds. But how well the library system succeeds depends on the staff committed to providing the highest possible level of service to the community. The public library, therefore, should employ the appropriate number of full-time staff. In order to warrant such a work force, this study analyzed the juridical justification, logical validity, realistic fitness, and usefulness of current legal and recommended staffing standards. This study also suggested the revisions of total space of buildings and collection size as crucial variables for library staffing, division of legal service populations, basic staffing level, and additional staff in proportion to service populations for public libraries in Korea.

Demand for text arranged in a circular shape is increasing as devices with round display such as smart watches are now being actively released. Data visualization field is receiving a lot of attention as the era of big data evolves. However, current web standard does not support the drawing of circular text. Therefore, the objective of this study was to extend CSS3 specifications to have circular text layout in web documents. In addition, we implemented a preprocessor so that contents made with CSS3 extensions could be shown in existing browsers. To confirm the wide expression range of CSS3 extension, we prepared some sample contents and analyzed them.

Incorrect deployment of RFID readers occurs reader-to-reader interferences in many applications using RFID technologies. Reader-to-reader interference occurs when a reader transmits a signal that interferes with the operation of another reader, thus preventing the second reader from communicating with tags in its interrogation zone. Interference detected by one reader and caused by another reader is referred to as a reader collision. In RFID systems, the reader collision problem is considered to be the bottleneck for the system throughput and reading efficiency. In this paper, we propose a novel RFID reader anti-collision algorithm based on evolutionary algorithm(EA). First, we analyze characteristics of RFID antennas and build database. Also, we propose EA encoding algorithm, fitness algorithm and genetic operators to deploy antennas efficiently. To show superiority of our proposed algorithm, we simulated our proposed algorithm. In the result, our proposed algorithm obtains 95.45% coverage rate and 10.29% interference rate after about 100 generations.

This study was conducted to analyze the effects of person-environment fit on the job performance in the National Assembly legislative support organization. Job performance was classified into task performance, contextual performance, and adaptive performance. Impacts of each factors on the job performance were identified through structural equation model. From the results of analysis, it was confirmed that supplementary fit of officials of legislative support organization of the National Assembly had a positive effect on task performance, contextual performance, and adaptive performance. However, complementary-fit does not directly affect task performance, contextual performance, and adaptive performance. Rather complementary-fit affects job performance by the mediating role of variable self-efficacy. The implications of this study confirm that it is important to match between organization members and jobs in order to improve the job performance of civil servants in the legislative support organization. The necessity of introducing self-efficacy enhancement program into the education and training process of the legislative support organization was proposed.
