Objectives: The purpose of the study was to identify the factors influencing the nursing students' core competencies on disaster nursing. Methods: A sample of convenience was 224 nursing students, and a questionnaire was used to measure their disaster awareness, disaster preparedness, ego-resiliency, and core competencies on disaster. Results: A significant positive correlation was found among core competencies, disaster awareness, disaster preparedness, and ego-resiliency. Disaster preparedness(${\beta}=.413$), grade of which the participant was in(${\beta}=.165$), satisfaction on clinical practice(${\beta}=-.160$), ego-resiliency(${\beta}=.159$), and disaster related education experience(${\beta}=-.120$) were significant predictive variables of which accounted for 38.5% of the variance in core competencies. Conclusions: The results from this study can be used to develop programs for core competencies on disasters nursing.

The aim of this study was to identify the convergence influencing factors on disaster nursing core competencies of nursing students. The subjects of this study surveyed 187 nursing students in D city with a structured self-report questionnaire. Data were analyzed by the SPSS 18.0 program, t-test, ANOVA, correlation and multiple regression. The disaster nursing core competencies average mean score was 3.15(±0.40). Grade and satisfaction of clinical practice were the significant factors related to disaster nursing core competencies in these subjects. Disaster nursing core competencies was positively correlated with disaster perception, disaster attitudes and self-efficacy. The influencing factors on disaster nursing core competencies were self-efficacy(β=0.276), disaster attitudes(β=0.200) and grade(β=0.172). The explanatory power of these variables was 19.1%. Therefore, it is necessary to develop disaster related curriculum and subjects that can improve the disaster nursing core competencies based on the important factors affecting the disaster nursing core competencies.

The objective of this study was to investigate the effect of an education method applying the flipped learning technique for college students. Both self-directed learning readiness and educational performance before and after applying the flipped learning were examined. After applying the flipped learning technique, teacher-student interaction, learning satisfaction, and learning motivation were identified. The correlation of each variable was examined after applying the flipped learning technique to investigate its influence on learning motivation. A total of 68 second-year nursing students enrolled in E University were analyzed. A difference between before and after applying the flipped learning was analyzed by the paired t-test; a correlation between the variables was analyzed via Pearson's correlation coefficient; and an influence on the dependent variable learning motivation was analyzed using the stepwise multiple regression analysis. The results showed that self-directed learning readiness increased before and after applying the flipped learning technique with statistical significance, and the difference of educational performance was not significant. After an education session applying the flipped learning technique, a learning motivation demonstrated a significantly positive correlation with self-directed learning readiness (r=0.33, p=.006), college student educational performance (r=0.51, p<.001), teacher-student interaction (r=0.72, p<.001), and learning satisfaction (r=0.79, p<.001). A significantly positive correlation was also observed between the other variables. Factors influencing learning motivation were learning satisfaction and teacher-student interaction. The explanatory power for learning motivation in the regression model considering these two variables was 71.3% (F=80.66, p<.001). Therefore, to enhance learning motivation in applying the flipped learning technique, it is necessary to increase learning satisfaction and to establish a strategy that further vitalizes the teacher-student interaction.

Micro LED, which is emerging as a next generation display, is difficult to commercialize due to various technical problems to date. In particular, transfer technology that transfers small LED to a display substrate in micro units is a key technology that can bring commercialization and is an important variable. The core of transfer technology is to move the LED quickly and accurately to the desired location. Therefore, it is necessary to pay attention on the transfer technology which is the most important task of Micro LED, and we analyzed and summarized the transfer technology using Elastomer Stamp which is one of the advanced transfer technologies.

최근의 많은 연구에서 정보기술에 대한 서비스제공 및 서비스 질(qualiy)에 대한 평가와 측정도구의 개발이 활발하게 이르어져 왔다(Pitt et al 1998) 또한 서비스 주체가 인적 요인에서 무형의 매체로 전환되고 있으며, 이러한 원인은 정보기술의 응용성에서 찾을 수 있다. 따라서 본 연구에서는 기존의 서비스 관점을 정보기술의 응용분야의 한 핵심이 될 수 있는 정보통신분야의 이동 휴대통신을 중심으로 서비스 질을 평가하여 문제점과 대안을 탐색하고자 하였다. 정보통신분야는 기간산업으로서의 역할과 그 중요성이 더욱 증대되고 있으며, 개별 기업차원에서도 정보기술 인프라는 중요한 경쟁요인이 될 수 있다. 그러나 이 분야에 대한 연구가 미흡하고 단순한 지표를 통한 비교 등의 연구 방법론에 있어서도 미비하다고 볼 수 있다. 따라서 본 연구에서는 정보통신분야의 중요성을 인식하고 초기 단계의 이동 휴대통신 분야의 핵심역량을 규명하고 향후 서비스 전략의 성공요인을 찾아내고자 하였다. 이러한 연구를 수행하기 위해 서비스만족 변수를 대리 측정도구로 이용하여 정보통신 기술 부분, 정보제공 부분, 비용우위 및 차별화 부분을 통해 계층적으로 접근하였다. 본 연구의 결과는 크게 세부분으로 요약된다. 첫째, 정보통신기술 부분에 대해 혁신적이고 안정적일 때 서비스만족도는 우수한 것으로 분석되었다. 또한 통신장비 및 부가장비의 우수성도 서비스부분에 미치는 영향력이 큰 것으로 나타났다. 둘째, 정보제공과 서비스만족과의 관계에서는 필요정보에 대한 서비스 밀착도가 높으면 서비스만족도는 높은 것으로 분석되었다. 또한 정보제공 분야의 서비스 개발력은 서비스만족도에 미치는 영향정도도 크게 작용하는 것으로 나타났다. 셋째, 차별화 및 비용우위와 서비스만족과의 관계도 매우 유의한 것으로 분석되었다. 특히, 비용 및 요금은 서비스만족도에 결정적 영향변수로 나타났으며, 광고 및 홍보부분도 만족도의 영향변수로 분석되었다. 이러한 연구결과는 향후 서비스전략에 응용될 수 있으며, 이동 휴대통신분야의 성공요인을 가시적으로 분석할 수 있다. 본 연구의 한계점은 첫째, 실제 서비스를 제공하는 서비스 주체의 객관적인 평가가 부족하였고 이러한 상횡에서 정보통신 기술 서비스 능력이 잘 반영되지 못했다는 점을 들 수 있다. 둘째, 이동 통신의 분야별 연구를 통해 비교 평가가 세부적으로 이루어지지 못했으며 연구방법상 샘플조사의 한계와 객관적인 응답자료를 확보하기가 어려웠던 점을 들 수 있다. 마지막으로 분석결과에서는 변수간의 유의성이 있는 것으로 볼 수 있지만 측정도구가 미약하며, 향후 지속적인 연구와 측정도구의 개발이 필요하다고 볼 수 있다.

The purpose of this paper is to take a look the effect of the physical security level of companies possessing national core technology on security performance and work efficiency. To this end, a survey was set out for about 200 security officers for a month. In the survey, the independent variable was physical security level, the parameter was security performance, and the dependent variable was work efficiency. Reliability analysis, validity analysis, discriminant validity analysis, etc. were analyzed for causality through SPSS. As a result, "Physical Security Level ⇒ Security Performance, Security Performance ⇒ Work Efficiency" was adopted, but "Physical Security Level ⇒ Work Efficiency" was rejected. Therefore, it was found that the physical security level affects work efficiency through security performance, which is a parameter. However, it was found that the physical security level did not directly affect work efficiency. In order to improve work efficiency in the future, improving security performance should be a priority.

A key issue in the development and application of stated preference nonmarket valuation is the incorporation of unobserved heterogeneity in utility models. Two approaches to this task have dominated. The first is to include individual-specific characteristics into the estimated indirect utility functions. These characteristics are usually socioeconomic or demographic variables. The second employs generalized models such as random parameter logit or probit models to allow model parameters to vary across individuals. This paper examines a third approach: the inclusion of psychological or 'latent' variables such as general attitudes and behaviour-specific attitudes to account for heterogeneity in models of stated preferences. Attitudinal indicators are used as explanatory variables and as segmentation criteria in a choice modelling application. Results show that both the model significance and parameter estimates are influenced by the inclusion of the latent variables, and that attitudinal variables are significant factors for WTP estimates.
