Purpose: The purpose of this study is to examine the effects of a competency based safety and quality improving education program for undergraduate nursing students. Methods: A quasi-experimental study of a non-equivalent control group pre and post test design was used. The participants were sixty-eight undergraduate nursing students recruited from the two universities in G and M cities. They were assigned to either a treatment group (n=35) or a comparison group (n=33). A five-day educational program developed based on the ADDIE Instructional Design Model was offered to the treatment group whereas the comparison group did not receive any instruction. Data were collected using self-report structured questionnaires. The data were analyzed using the SPSS/WIN 21.0 with the $x^2$ test, and independent t-test. Results: The students in the treatment group reported significant positive changes for patient safety knowledge, skill and perception of quality and safety competencies. Conclusion: Findings from this study supports that competency based quality improving and safety education program is a useful intervention strategy to promote student's knowledge, skill and perception of quality and safety competencies.

Purpose: Present study was designed to examine the casual relationships among tourism information service quality, value, user satisfaction, and reuse intention in social network service(SNS). Also, we intended to testify the mediating role of value in causal model. We applied path analysis model in order to test the hypotheses and research model. Methods: Survey tool, that is, questionnaire has obtained validity through literature survey, exploratory survey and pretest and sample 272 was selected. For statistical treatment of pretest and main analysis, SPSS18.0 and AMOS18.0 were employed and structural equation model was employed as analysis method. Results: Result of this study shows as follows. Two factors(ease of understanding and structure) have an effect on user satisfaction and reuse intention, and we found that value played a significant and important role in causal relationship. Therefore, value was empirically confirmed as t he import ant fact or preceding user satisfaction and reuse intention. Conclusion: Present study shows that two factors(ease of understanding and structure) in via of value, were important factors that related business companies have to emphasize to raise performance. However, present study has some limitations to additionally research in the future.

The main objective of this study was to test the impact of service quality dimensions on customer satisfaction. The conceptual model proposed in the study postulated that service quality impacts on customer satisfaction directly. The model also postulated that service quality has a positive relationship with customer satisfaction, and tested them through Multiple Regression to find their significance. Questionnaires were distributed to gather data. The SERVQUAL instrument has a useful diagnostic role to play in assessing and monitoring service quality in banks. The results of the study confirmed the five factors of service quality with customer satisfaction were significant in all factors of service quality. Reliability, Responsiveness, Empathy, Assurance, and Tangibles are significant determinants of customer satisfaction. Thus, service quality can be used to predict customer satisfaction. The research has shown a positive relationship between service quality and customer satisfaction. This research concluded that service quality is the basic and also most important factor that impacts customer satisfaction. This finding reinforces the need for banks managers to place an emphasis on the underlying dimensions of service quality, especially on Assurance, and should start with improving service quality in order to raise customer satisfaction.

The pressure drop of a moisture separator in a steam generator is the important design parameter to ensure the successful performance of a nuclear power plant. The moisture separators have a wide range of operating conditions based on the arrangement of them. The prediction of the pressure drop in a moisture separator is challenging due to the complexity of the multi-dimensional two-phase vortex flow. In this study, the moisture separator test facility using the air/water two-phase flow was used to predict the pressure drop of a moisture separator in a Korean OPR-1000 reactor. The prototypical steam/water two-phase flow conditions in a steam generator were simulated as air/water two-phase flow conditions by preserving the centrifugal force and vapor quality. A series of experiments were carried out to investigate the effect of hydraulic characteristics such as the quality and liquid mass flux on the two-phase pressure drop. A new prediction model based on the scaling law was suggested and validated experimentally using the full and half scale of separators. The suggested prediction model showed good agreement with the steam/water experimental results, and it can be extended to predict the steam/water two-phase pressure drop for moisture separators.

The quality of products produced by injection molding process is greatly influenced by the process variables set on the injection molding machine during manufacturing. It is very difficult to predict the quality of injection molded product considering the stochastic nature of manufacturing process, because the process variables complexly affect the quality of the injection molded product. In the present study we predicted the quality of injection molded product using Artificial Neural Network (ANN) method specifically from Multiple Input Single Output (MISO) and Multiple Input Multiple Output (MIMO) perspectives. In order to train the ANN model a systematic plan was prepared based on a combination of orthogonal sampling and random sampling methods to represent various and robust patterns with small number of experiments. According to the plan the injection molding experiments were conducted to generate data that was separated into training, validation and test data groups to optimize the parameters of the ANN model and evaluate predicting performance of 4 structures (MISO1-2, MIMO1-2). Based on the predicting performance test, it was confirmed that as the number of output variables were decreased, the predicting performance was improved. The results indicated that it is effective to use single output model when we need to predict the quality of injection molded product with high accuracy.
