Although the weapon systems are becoming more diverse and complex, they are progressing in a short development period and a longer test and evaluation period. The more difficult the given environment is, the more efforts and performance of quantitative target values can be made by development agencies to carry out stable projects. However, these target values of the Integrated Logistics Support are not specified in the requirements and being set during the system development phase. In this paper, application of MOEs, MOPs and TPMs for ILS are presented and provided the basis for carrying out systematic Verification & Validation activities. As a result that MOEs of the ILS were chosen as Availability and MOPs as Mission Reliability, Logistics Reliability, Maintainability and Supportability and TPMs as MTBF, MTBCF, MTTR and so on. In particular, it is appropriate tailoring and apply the TPMs considering the cost, schedule, scope of work and characteristics of the project.

Past studies on the influence of corporate social responsibility (CSR) activities on firms have been inconsistent, highlighting the significance of examining how CSR affects the performance of Malaysian government-linked companies (GLCs). The study aims to investigate the impact of CSR dimensions (economic, legal, ethical, and philanthropic) on firm performance from 2016 to 2020 using a sample of 31 GLCs from the top 100 companies under the Main Board of Bursa Malaysia. A total of 35 GLCs were selected as the study sample size based on the top 100 businesses listed under the board of Bursa Malaysia as of 31 December 2020. The study employed correlation and multiple linear regression models to examine the relationship between CSR dimensions and firm performance. Financial performance is evaluated using accounting-based models of return on assets (ROA) and return on equity (ROE) and market-based models of earnings per share (EPS) and market value (MV). The CSRHub database was employed to collect information on the performance of company CSR dimensions. The findings suggested a significant positive relationship between ethical and philanthropic CSR and firm performance regarding ROE. Thus, GLCs prioritized ethical and philanthropic CSR over other dimensions.

조직의 정보보안을 위해서는 세 가지 유형의 정보보안(기술적, 물리적 및 관리적 보안) 모두가 중요하며 병행 추진되어야 할 것이지만, 본 연구는 관리적 보안대책의 수립 및 추진의 효과성을 보다 높이기 위한 이론적 근거를 확보하는데 연구목표를 설정하였다. 즉, 기술적 및 물리적 보안대책이 철저하게 정비되고 추진된다고 하더라도 이를 준수하고 실행하는 주체는 결국 조직구성원들이므로 기술적 및 물리적 보안대책이 소기의 성과를 이루기 위해서는 이에 부응한 관리적 보안대책이 균형 있게 추진되는 것이 필수적이기 때문에 관리적 보안을 보다 효과적으로 수행할 수 있기 위한 이론적 근거를 확보하는 것은 매우 중요한 의미를 지닌다고 본다. 특히, 본 연구에서는 효과적인 관리적 보안대책의 수립 추진의 핵심과제라고 할 수 있는 조직구성원들의 정보보안기술 사용의도를 향상시키기 위한 방안 마련 시에 적용될 수 있는 이론적 모형을 개발 제시하고자 하였다. 이를 위해 정보보안기술 사용의도에 영향을 미치는 요인들을 주요 관련 이론 및 선행연구들에 대한 체계적 고찰을 통해 도출하고 이들 간의 인과적 관계를 논리적으로 추론함으로써 연구모형 및 가설을 도출하였다. 실증분석을 위해서는 국내 대기업들의 직원들을 대상으로 현장서베이를 통한 자료수집을 하였고 부분최소자승법(PLS: Partial Least Squares)기법에 의한 구조방정식 모형분석을 실시하였다. 본 연구의 유의한 결과는 이론적인 측면에서 관리적 정보보안 분야 연구의 외연을 확대하는데 기여할 수 있다고 보며, 실무적인 측면에서는 제반 조직들이 관리적 정보보안 방안 및 대책 수립을 함에 있어서 업무지침의 일부로 적용될 수 있을 것으로 예상된다.

The main purpose of this research is to measure and analyze how productive the health centers are and how much inputs(or outputs) in the inefficient health centers should be decreased(or increased) for efficiency. The evaluation of the performance of health centers gives a strong incentive to improve resource allocation in regional health planning. It has been, however, implemented very rarely until now. In this regard, this paper measures the performance of the health centers with a single indicator for multiple-outputs in terms of productivity(technical efficiency), based on Data Envelopment method. The 20 Kyungnam health centers which provide clinic services and specific primary health care services were analyzed. The results show that 50.0% of 20 health centers were productive with respective to overall technical efficiency, 65.0% were productive for pure technical efficiency, and 50.0% for scale efficiency. The inefficient group includes Geoje, Mahsan, Miryang, Sahchun, Tongyoung, Gosung, Nahmhae, Euryang, Hahmahn, Hahbchun health centers. The worst case was identified as Tongyoung health center which represented a 47.5% efficiency, compared with productive health centers. The empirical results for input-output analysis indicates that the low-productive health centers have excessive manpower in administration department, producing low outputs in clinical services and vaccination program. These findings imply that a systemic evaluation of the performance of the Korean health centers and the subsequent structural reform are strongly required.

Purpose : The first case of coronavirus disease-2019 (COVID-19) disease outbreak in Korea occurred in January 2020, and the cumulative number of confirmed cases by the Central Defense Response Headquarters of the Quality Management Administration as of November 30 was 34,201. Looking at the incidence trend of domestic confirmed cases by age, the incidence rate of COVID-19 in the age group of 20-29 years, which corresponds to college students, was 27.4 %, the highest compared by age group. Considering the current status of the infection rate, universities will become the centers of new COVID-19 cases if face-to-face lectures are recommenced without preparatory measures and analysis of infection prevention (e.g., infection awareness and education for university students). Thus, this study intended to investigate the level of knowledge, educational needs, and preventive behavior performance of college students about COVID-19 and provide basic data for the development of an education program for the prevention of COVID-19 for college students. Methods : This study is a descriptive correlational study aimed to investigate the correlation between knowledge about COVID-19, educational needs, and degree of preventive behavior performance in 407 college students attending one University in Gyeonggi-do. Results : The subjects' knowledge score about COVID-19 was 12.46±1.39 points, average educational needs score was 29.16±3.14 points, and prevention behavior performance survey result was 35.50±3.61 points. Moreover, positive correlation was observed between the knowledge about COVID-19 and educational needs (r=.203, p<.001) and knowledge and preventive behavior performance (r=.140, p=.005). Further, educational needs and preventive behavior performance demonstrated a statistically significant positive relationship (r=.311, p<.001). Conclusion : Therefore, organizing an educational program to acquire accurate knowledge is necessary to make it a habit for college students to practice preventive behavior against COVID-19.

The major objective of this paper is to empirically examine the effect of process maturity on the performance of industrial R&D projects. Process maturity, a fundamental concept of the Capability Maturity Model developed by Software Engineering Institute, represents the essential of Total Quality Management (TQM). Based on literature, our research model constructs process maturity in terms of structured process, goal setting and controlling, metrics, and process learning; and links it to the R&D performance that consists of technical, commercial and managerial successes. The model also includes firm size as a moderator of different effects that process maturity may have across firms. Measures for process maturity are based on the best practices identified in literature. Data are obtained from 77 successful R&D projects carried out by Korean manufacturing firms. Multiple regression and t-test are used to test proposed hypotheses. Findings are as follows. (1) In the R&D process, process maturity partially contributes to the performance of R&D projects. More specifically, goal setting and controlling-related practices drive both technical and commercial successes, while process learning-related practices drive commercial success. In contrast, traditionally emphasized elements such as structured process or metrics are found not to be significant. (2) The degree of process maturity is significantly higher in large firms. (3) Process maturity impacts on commercial success in the case of large firms, whereas it does on technical success in the case of small firms. The results imply that the TQM principles are partially associated with R&D performance, and the nature of benefit from high maturity could vary according to firm size.

본 연구는 국제원자력기구(International Atomic Energy Agency: IAEA)의 원자로정보시스템(Power Reactor Information System: PRIS)에서 제공하는 원자로 운전실적지표를 이용하여 원전의 안전성에 미치는 기술적 비기술적 요인의 역할을 분석한다. 이를 위해 안전성의 척도로 원전의 고장정지에 따른 발전손실률 (FLR: forced loss rate)을 사용했다. 1970년부터 2015년까지 전 세계에서 운영된 모든 원전으로 구성된 패널자료를 통해 분석한 결과, 기존 연구와 마찬가지로 원전의 전반적인 기술수준과 정비기술수준이 향상될수록 FLR이 하락하는 사실을 확인했다. 하지만 1986년 체르노빌 원전 사고 이후 기술적 요인이 통제된 FLR은 유의적으로 상승했다. 이는 원자력발전사업자가 체르노빌 사고 이후 원자력안전을 위해 보다 많은 기회비용을 지불하고 있다고 해석된다.

Due to design codes and regulations and the variety of building plans in Turkey, it is very often seen that band-type windows are left for ventilation and lightening of the basements of buildings which are used for various purposes such as workplaces and storage. Therefore when the necessary support measures cannot be given, short columns are subjected to very high shear forces and so damage occurs. One of the precautions to avoid the damage of short column mechanisms in buildings where band-type windows are in the basement is to strengthen the short columns with fiber reinforced polymer (FRP). In this study, the effect of the FRP retrofitting process of the short columns around band-windowed structures, which are found especially in basement areas, is analyzed in accordance with Turkish Seismic Code 2007 (TSC 2007). Three different models which are bare frame, frame with short columns and retrofitted short columns with FRP, are created and analyzed according to TSC 2007 performance analysis methods to understand the effects of band windows in basements and the effect of FRP retrofitting.
