In order to ensure the safety of the large-scale public facilities, the analysis of EMC(ElectroMagnetic Compatibility) of electronic systems included in the facilities is very necessary. The reason is that the system-level EMC of the facility could be not guaranteed, even if individual equipments included in the facility are satisfied with their EMC requirements. As a result, the system-level evaluation and analysis of EMC should be carried out in order to establish the reliable operations of safety and mission-critical electronic systems. This paper analyze the relevant legal systems of domestic and other countries, and furthermore case studies of system-level EMC approaches were analyzed in the specific applications of electric railways, building, automobile, petroleum refinery systems. And the introduction of related systems in Korea is proposed, and main parts and problems to be looked at each proposed measures are discussed. The results are expected to be utilized in the introduction of the system-level EMC engineering, and contributed in national security and the protection of people's life, body and their properties.

The objective of the study was to explain the effect of job fit on life satisfaction of wage workers and verify the mediating effect of job satisfaction between two variables. For the purpose, 7,202 research subjects were selected from the 23th data of the Korean Labor and Income Panel Study. Selected data was analyzed by various methods including frequency analysis, descriptive statistics analysis, and correlation analysis. Moreover, the mediating effect was verified by applying SPSS Macro Model Number 4 analysis and bootstrapping method. The major findings are as follows. First, job fit of wage workers was shown to enhance their life satisfaction. Second, work satisfaction of wage workers was revealed to play a complete mediating role in the relationship between job fit and life satisfaction of wage workers. On the basis of the results, the various practical programs to increase life satisfaction of wage workers were discussed.

This study aims to identify the major recent research trends on person-organizational fit, and uses SCOPUS, an academic database, to identify research trends on person-organizational fit over the past 24 years (2000-2023). Frequency analysis showed that organizational was the most important term with 2,789 articles, followed by effectiveness with 2,714 articles, management with 850 articles, performance with 689 articles, organizations with 632 articles, and leadership with 597 articles. The trend analysis shows that research on fit, organization, and job is steadily increasing. The LDA analysis showed that fit, personorganization(po), and job are important topics, which shows that fit, i.e., the alignment of an individual's goals or values with the organization's goals or values, is important in the operation of an organization. The results of this study can be used as a useful guideline for organizations to establish measures to attract and cultivate excellent human resources and create organizational performance.

Proportional hazards model has been widely used for analyzing survival data. This article reviews some well-known goodness-of-fit tests for proportional hazards model. Simulation studies also provide some insights into the properties of these test statistics across several types of survival distributions and degerees of censorship.

In this paper, a test of fit for Weibull distribution on the estimated Kullback-Leibler information is proposed. The test uses the Vasicek entropy estimates, so to compute it a window size m must first be fried, and then is obtained critical values computed by Monte Carlo simulations. The power of the proposed test under various alternatives is compares with that of ocher famous tests. The use of the test is shown in an illustrative example.

For analyzing the performance determinants of ODA projects in a technical and vocational education and training, this research analyzed the performance determinants of effectiveness representing the direct benefit and impact representing the long-term development effects of ODA project using FsQCA. As a result, the effectiveness of ODA project is achieved when relevance, sustainability and impact are high, or relevance, impact and efficiency are high. The impact of ODA project is achieved when relevance, sustainability and effectiveness are high, or relevance, effectiveness and efficiency are high. Two solutions for achieving effectiveness and two solutions for achieving impact show equifinality. The core factors for achieving effectiveness are relevance and impact, and the core factors for achieving impact are relevance and effectiveness. Also sustainability and efficiency are substitutability. A single causal variable can not have an effect on the ODA performance, but combined more than three causal variables can have an effect on the ODA performance. Therefore this research verified that collectives of causal variables rather than single causal variable should be considered to achieve the performance of ODA project in technical and vocational education and training.

The purpose of this study is to analyzed that the perceived price and VMD fitness of the SPA(speciality store retailer of Private label Apparel) brand characteristics impacts on multidimensional commitment consist of affective commitment, calculative commitment and behavioral commitment. Using SPSS 18.0 and AMOS 18.0 by structural equation modeling analysis, we found that perceived price have effects on affective commitment, behavioral commitment and calculative commitment significantly, and VMD fitness have effects affective commitment significant only. Affective commitment and calculative commitment on behavioral commitment was affected significantly. Through this study we found that perceived price and VMD fitness SPA brand maintaining relationships between the consumer and the seller are an important factors.
