The purpose of this study is to prepare educational contents and criteria for selecting advertisement materials by exploring the necessity of value system education in Korean culture education. Furthermore, the study aims to suggest advertisements that contain meaningful materials through the criteria among the public and commercial advertisements as of 2017. Advertisements have advantages in three aspects as they focus on current culture, cultural implications and the ease of teaching and learning. These advantages indicate the usefulness of advertisements in value education. Also, the research of Hofstede (2010), Kang (2007), and Kim et al. (2011) provide discussion regarding educational contents. Subsequently, the criteria for selecting advertisements are further developed as the main purpose of this study. The criterion are to consider the objectives of culture education, to take into account the learning situation, to find relevance between the contents of the advertisement and the contents for the value system education, and consider expressive methods of advertisements and extensibility to the activities. Next, advertisements were selected for core educational items and the list of 22 is presented according to the value system, educational contents and the criterion of the advertisements discussed in the above.

This study was carried out to evaluate the renewable energy dissemination programs in Korea, using peer-review. Especially, we used the peer review method which was suggested to evaluate the renewable energy program in U.S. by EERE, DOE. Before we implemented the peer review, we modified this method suitable for evaluating the renewable energy dissemination programs in Korea by getting advice from expertise in renewable energy policy. From this procedure, we have verified six evaluation criteria as Quality, Productivity, Accomplishments, Relevance and Management. We interviewed renewable energy policy expertise and corporation to evaluate the programs against these criteria. The result shows that overall programs were performed more than average. In addition, both the policy expertise and corporation perceived that "oan Guarantee Program" and "ompulsory Installation of Renewable Energy Facility in Public building" fulfilled its role to a great extent. However, the respondents pointed out that all of the programs need to be improved on its management.

The measurement of informatization program effectiveness continues to be a central concern of both academics and practitioners. However, most studies of it have been inclined too heavily toward testing validity and reliability of evaluation measure to strengthen the theoretical rigor. Drawbacks of this approach have been pointed out as being unsuitable for evaluating the effectiveness of informatization program due to lack of practical relevance. The paper comprises four sections to solve the problem. 1) Through literature review of theoretical conceptual models in IS effectiveness and the domestic and foreign cases on informatization program, we establish the evaluation framework which consists of evaluation phases, 6 evaluation areas, and 22 evaluation items, and developed evaluation measures of each items. 2) Different researchers have addressed different aspects of attribute of measure. With comparing them to each other, 3 mutually exclusive criteria on coincidence analysis(usability of measurement. reliability of measurement. and validity of content) are identified. 3) Data are gathered from respondents in informatizaiton program-related organizations such as policy agency, management agency, support agency, and recipient agency. 4) The degree of coincidence of each evaluation measure are analyzed by course of an coincidence analysis procedure, which includes the reliability test, arithmetical test, and criteria validity test. The academic implication of this study is that researchers can gain an insight into the coincidence analysis to approach the problem of deciding on an indicator of performance for informatization program. There is also practical implication for applying the potential means of improving the practical relevance of conducting evaluating the informatization program.

Every public agency governing infrastructure has to plan effectively for rehabilitation of existing facilities within the constraints of the capital program. Numerous technical, social, political, financial, and management constraints govern the decision to rehabilitate a facility. However, without a systematic procedure for selecting facilities for rehabilitation, within the prevailing constraints, it is possible that the funds available for rehabilitation might be suboptimized. Therefore, a decision support system that assists the user in selecting facilities for rehabilitation while considering the technical, social, financial, and political and management constraints will be useful in the decision-making process. This paper compares the Analytical Hierarchy Process (AHP) with the Swing Weight method used to prioritize functional criteria for suburban station rehabilitation. This paper also contains a brief discussion about the relevance of the Multi Attribute utility theory in developing a decision model for the problem at hand. The results of this paper provides the user with a decision support system that would prioritize the stations in order of their weights obtained by a systematic evaluation of various criteria and sub-criteria involved in the decision making process

Objective: The Korean Triage and Acuity Scale (KTAS), which was implemented in 2016, needs to be assessed for its validity and reliability. Here we evaluate the relevance of emergency level assessment by analyzing the validity of KTAS as a Korean standardized triage system. Methods: We retrospectively analyzed the medical records of adults who presented to a local emergency room (ER) during an 18-month period. We compared medical resources used, life-saving interventions performed, length of stay (LOS) in ER, admission rate, and mortality at each KTAS level. Results: Among a total of 40,339 patients, most patients were at KTAS 4 (n=19,532, 48.4%) and the longest median LOS in ER was 450 minutes at KTAS 2. As the KTAS level increased, the percentage of medical resources used and lifesaving interventions performed increased significantly. The odds of total admission and intensive care unit admission were significantly higher at KTAS 1 through 4 compared to those at KTAS 5. The odds related to admission and mortality were also significantly higher at KTAS 3 than at KTAS 4. Conclusion: We concluded that the KTAS, as a Korean standardized triage system of emergency level assessment, is relevant. Further, KTAS 1-3 and KTAS 4-5 are appropriate criteria to distinguish emergency and non-emergency patients.

This study aimed to investigate the relevance of cardiovascular disease risk factors AI and AIP, divided into three groups, among 300 individuals who underwent health checkups at the hospital. Various variables such as Age, Sex, BMI, WC, TC, TG, HDL-C, LDL-C, FBS, HbA1C, SBP, DBP, HR, AI (TC/HDL-C), and AIP (log(TG/HDL-C)) were analyzed using statistical methods including frequency analysis, cross-tabulation, one-way ANOVA, Pearson's correlation analysis, and multiple linear regression analysis. The cross-analysis based on cardiovascular disease risk criteria revealed that men and individuals in their 50s had higher cardiovascular disease risk based on AI and AIP. Significant differences were observed in TG, TC, HDL-C, LDL-C, SBP, DBP, AI (TC/HDL-C), and AIP (log(TG/HDL-C)) according to AI criteria. For the AIP criteria, TG, TC, HDL-C, FBS, HbA1C, HR, AI (TC/HDL-C), and AIP (log(TG/HDL-C)) were identified as cardiovascular disease risk factors. FBS and HbA1c showed the highest positive correlation In the correlation analysis, followed by TC and LDL-C. The lowest positive correlation was observed between LDL-C and DBP. In terms of negative correlation, HDL-C and AI had the highest negative correlation, while LDL-C and TG showed the lowest negative correlation. Multiple regression analysis indicated that the AI and AIP risk criteria had explanatory powers of 73.6% and 72.5%, respectively. HDL-C had the greatest negative effect on the AI risk criterion, while TG had the most significant influence on the AIP risk criterion. In conclusion, while other serological variables are important, managing HDL-C and TG levels may help reduce the risk of cardiovascular disease.
