In this study, a novel single phase soft switched power factor correction (PFC) converter is developed with active snubber cell. The active snubber cell provides boost switch both to turn on with zero voltage transition (ZVT) and to turn off with zero current transition (ZCT). As the switching losses in the proposed converter are too low, L and C size can be reduced by increasing the operating frequency. Also, all the semiconductor devices operate with soft switching. There is no additional voltage stress in the boost switch and diode. The proposed converter has a simple structure, low cost and ease of control as well. It has a simple control loop to achieve near unity power factor with the aid of the UC3854. In this study, detailed steady state analysis of the proposed converter is presented and this theoretical analysis is verified by a prototype of 100 kHz and 500 W converter. The measured power factor and efficiency are 0.99 and 97.9% at full load.

This paper uses 135 Licensed Operator Event Reports (LOER) from Chinese nuclear plants to analyze how safety culture affects unsafe behaviors in nuclear power plants. On the basis of a modified human factors analysis and classification system (HFACS) framework, structural equation model (SEM) is used to explore the relationship between latent variables at various levels. Correlation tests such as chi-square test are used to analyze the path from safety culture to unsafe behaviors. The role of latent error is clarified. The results show that the ratio of latent errors to active errors is 3.4:1. The key path linking safety culture weaknesses to unsafe behaviors is Organizational Processes → Inadequate Supervision → Physical/Technical Environment → Skill-based Errors. The most influential factors on the latent variables at each level in the HFACS framework are Organizational Processes, Inadequate Supervision, Physical Environment, and Skill-based Errors.

Objectives : To assess the degree of quality improvement (QI) implementation and to identify its associated factors. Methods : A mailed questionnaire survey of the QI staffs at hospitals with 400 beds or more was conducted between September 15 and October 30, 2000. Of the 108 hospitals eligible for inclusion in our study, 79 participated, yielding a response rate of 73.1%. After excluding 12 hospitals that did not perform any QI activities, 117 responses from 67 hospitals were used in our analysis. The degree of QI implementation was measured using the Malcolm Baldrige National Quality Award Criteria (MBNQAC). Factors evaluated for association with the degree of QI implementation were cultural, technical, strategic, and structural factors of the hospitals. Results : The average 01 implementation score across the 7 dimensions of MBNQAC was 3.34 on a 5-point scale, with the highest score for the area of customer satisfaction (3.88) followed by information and analysis (3.59) and quality management (3.35). The results of regression analysis showed that hospitals with a ofter information system (p<0.05) and using scientific and systematic problem solving approach (p<0.01) tended to perform a higher degree of QI implementation. While statistically insignificant, positive associations were observed for the factors of group or developmental culture, the degree of employee empowerment, and the use of prospective strategy. Conclusions : It appears that the most important factors contributing to active implementation of QI in Korean hospitals were the use of scientific skills in decision making, and having a quality information system to produce precise and valid information.

Purpose: The purpose of this study was to investigate the effects of simulation-based training (SBT) for basic life support (BLS) utilizing video-assisted debriefing (VAD) about non-technical skills (NTSs) and technical skills (TSs). The goal of the proposed study is the evaluation of a teaching method about the correct application of cardiopulmonary resuscitation (CPR). Methods: The study design was a control group pre- and post-test non-synchronized experimental design. The sample included twelve teams of 36 nursing students. Both the experimental and the control groups received the SBT for BLS. Only the experimental groups received VAD where as the control groups had a verbal debriefing. Raters who used checklists for TSs and NTSs evaluated both groups. Data were analyzed by the SPSS 20.0 using Cronbach's ${\alpha}$, Intraclass Correlation Coefficient (ICC), Mann-Whitney U test and Willcoxon signed rank test. Results: The experimental groups scored higher than the control groups in both TSs (p=.004) and the NTSs (p=.008). Conclusion: The findings of this study suggest that NTSs are an important factor that lead CPR successfully, so VAD can be used as an efficient teaching-learning strategy in the SBT for BLS for nursing students and nurses.

The objectives of this paper are to identify the causes of the corporate distress and to develop a distress prediction model with the financial information in fishery industry. In this study, the corporate distress is defined as economic failure and technical insolvency. Economic failure occurs by reduction, shut-down, or change of the business and technical insolvency results from failure to pay the financial debt of companies. The 33 distressed firms from 1991 to 2003 were composed by 14 economic failure companies, 15 technical insolvency companies. 4 companies applied to the both cases. The analysis of distress prediction of fishery companies were accomplished according to the distress definition. The analysis was carried out as two steps. The first step was the univariate analysis, which was used for checking the prediction power of individual financial variable. The t-test is used to identify the differences in financial variables between the distressed group and the non-distressed group. The second step was to develop distress prediction model with logistic regression. The variables showed the significant difference in univariate analysis were selected as the prediction variables. The financial ratios, used in the logistic regression model, were selected by backward elimination method. To test stability of the distress prediction model, the whole sample was divided as three sub-samples, period 1(1990$\sim$1993), period 2(1994$\sim$1997), period 3(1998$\sim$2002). The final model built from whole sample appled each three sub-samples. The results of the logistic analysis were as follows. the growth, profitability, stability ratios showed the significant effect on the distress. the some different result was found in the sub-sample (economic failure and technical insolvency). The growth and the profitability were important to predict the economic failure. The profitability and the activity were important to predict technical insolvency. It means that profitability is the really important factor to the fishery companies.

본 연구는 한국소비자원의 2013 한국의 소비생활지표의 원자료를 활용하여 기술적 정보를 제공하는 금융영역에서의 소비자 문제 경험을 확인하고, 이에 영향을 미치는 요소들을 탐색하였다. 금융 영역은 기술적 정보 영역에 해당하여 소비자 문제 경험 분석 시 지식 등 객관적인 역량 중심의 접근이 아니라 기술적 정보 영역의 특성에 근거해 융복합적 관점으로 영향요인을 탐색하는 것이 중요하다. 기술적 정보로서 금융영역에서는 정확한 정보의 제공 및 비교정보에 대한 요구가 높은 것으로 나타났다. 또한 문제경험에의 영향 변수를 탐색한 결과 소비자 개개인의 주관적인 금융 역량이 문제경험을 줄이는 것에 의미 있는 변수로 확인되었으며, 50대 이상의 고령 소비자들은 금융영역에서 더 많은 문제를 경험하고 있는 것으로 확인하였다. 이를 통해 기술적 정보 영역인 금융영역의 경우 금융정보의 효율적인 전달 방안에 관한 모색, 고령자에 대한 판매접점에서의 추가적인 노력 방안이 요구되며, 그 동안 객관적 금융역량을 강화하기 위한 방안에 초점이 맞추어져 있었으나, 향후 주관적 금융역량 강화를 위한 방안에 대한 연구가 요구된다.

Purpose: As the untact culture has spread due to the recent COVID-19, the service industry as well as the beauty salon is shrinking. In order to overcome such a crisis in beauty salons, the lower dimension of beauty salon service quality is divided into servicescape, technical service, and employee service, and actions are taken with the 'perceived value of the customer' as a parameter. In this study, S-O-R(Stimulus-Organism-Response) theory was applied for customer-centered analysis, and gender and regularity were selected as moderator variables to add practical implications. Research design, data, and methodology: All constructs were measured using items developed and used in the previous study. A total of 261 questionnaires were collected online using NaverForm. The data were analyzed using factor analysis, correlation analysis, and measurement model analysis with SPSS 22.0 and AMOS 22.0. After testing the research model and hypothesis for the entire group, a multi-group analysis was conducted by dividing into male and female groups, regular customers, and non-regular customers. Results: First, this study showed that the service environment of beauty salon customers had a negative (-) effect on perceived utilitarian value, and the technical service and perceived hedonic value had a positive (+) effect on the customer's behavioral intention. Technical service and employee service had a positive (+) effect on perceived hedonic value, but perceived hedonic value did not affect customer's behavioral intention. Second, there is no statistically significant difference in each path between male and female groups. Third, there was a statistically significant difference between regular customers and non-regular customers, only the path that the servicescape influences the perceived hedonic value. Conclusion: According to the results of this study, technical service and utilitarian value should be considered in order to induce behavioral intention of customers, and technical service quality should be considered first. Also, operating a beauty salon requires a differentiated approach to the salon servicescape according to the ratio of non-regular and regular customers. The beauty salon servicescape generally showed negative practical value for non-regular customers, but positive for the Hedinic value for servicescape such as comfortable service and clean interior for regular customers.
