South Korea is recently under serious situation in supplying electricity with enough power reserve. A single fault of power plant at a peak-load time may lead to a total blackout for whole area connected by a single electric grid and isolated from other grids. Despite of the seriousness of blackout, however, there are scarce studies with ex-ante analysis of the economic costs from blackout. In order to evocate the seriousness, we calculate the economic costs for both industrial and household sectors with using some survey data and statistical methodologies. As a result, total economic costs are 39.23 trillion KRW (35.83 trillion KRW for industrial sector, 3.40 trillion KRW for household sector).

In this paper, we propose a window-based mechanism visualization approach as an alternative way to measure the seriousness of the difference among data-insights extracted from a composite biodata point. The approach is based on two components: undirected graph and Mosaab-metric space. The significant application of this approach is to visualize the segmented genome of a virus. We use Influenza and Ebola viruses as examples to demonstrate the robustness of this approach and to conduct comparisons. This approach can provide researchers with deep insights about information structures extracted from a segmented genome as a composite biodata point, and consequently, to capture the segmented genetic variations and diversity (variants) in composite data points.

In effort to help vitalize environmental education which is the most efficient way to preserve environment and solve environmental problems and also to provide necessary basic data, this research was conducted on the primary and secondary school teachers in Daegu for their awareness of the elements of environmental education, for their interests in environment and environmental issues, for their sensitivity on the seriousness of the environmental issues and for their knowledge of environmental vocabulary. Followings are the results: 1. 96% of the teachers supported the necessity of school education on environment, but only 51% went for adopting environment as an independent subject. 2. The majority of 57% said that they came to recognize environment and environmental issues 'through media such as TV and radio'. For the desirable form of environmental education, 64% supported 'field study or experience activity'. As for the undermining factors, the majority of 50% cited 'excessive focus of school education on college entrance' and 29% 'limitations of class hours'. 3. With regard to their interests in environment and environmental issues, they were between 3.43～4.08 point range out of 5 points. For their sensitivity about the seriousness of environment and environmental problems, the survey showed the range of 3.49～4.28 points out of 5 points. 4. There was no remarkable difference in the level of recognition between male and female teacher. But, according to disparity of age, teachers who are in their forties and fifties recognized better than teachers in twenties and thirties. Also, there was a striking difference among primary school, middle school, and high school teachers. High school teachers had the highest recognition level, while, middle school teachers had the lowest recognition level.

Objectives: The purpose of this study is to investigate the factors of oral health beliefs on scaling performance by national health insurance coverage in consumers. Methods: The subjects were 353 people living in Seoul, Incheon, and Gyeonggi-do from September 25 to October 20, 2013. They filled out the self-reported questionnaire after receiving informed consents. The questionnaire included 6 questions of general characteristics, 6 questions of oral health behavior, 6 questions of health insurance coverage, and 1 question of subjective oral health recognition. The oral health belief consisted of 6 questions of seriousness, 6 questions of susceptibility, 8 questions of barriers, 5 questions of benefit, and 3 questions of self-efficacy measure by Likert 5 scale. Cronbach's alpha in the study was 0.759. Data were analyzed using SPSS version 20.0 for frequency analysis, t-test, ANOVA, post-hoc Scheffe test, Pearson's correlation coefficient, and binary logistic regression. Results: The influencing factors of oral health belief model were Seriousness(${\beta}=0.091$), Self efficacy(${\beta}=-0.471$) and age(${\beta}=0.855$)(p<0.05). Those who had highly perceived seriousness and younger age tended to have probability of scaling performance. Higher self-efficacy tended to take more chance to have scaling performance probability. Conclusions: In order to cover the scaling by national health insurance, it is very important to notice the benefit of health insurance coverage of scaling to the consumers. National health insurance coverage enables the scaling practice to be easily accessible to the people. Easy access to scaling by low cost strategy can improve the oral health behavior.

Objectives: This study was done to find factors related with performance of hepatitis B Vaccination among some aged persons through health belief model. Methods: A questionnaire survey was made during September 2004 toward 230 elderly persons using institutions for the elderly of Gwangju City. The relations between subjects characteristics including health belief, mass media contact, hepatitis B experience and performance of hepatitis B vaccination were tested by t test or X2 test. Multiple logistic regression analysis was done to find final significantly related variables. Results: 24.8% of the subjects were vaccinated against hepatitis B. By simple analysis of relation between performance of hepatitis B vaccination and subjects characteristics including health belief, significant variables were chosen as 6 variables including perceived susceptibility, perceived seriousness, perception of benefits, knowledge on hepatitis B, age, experience of hepatitis through family or friend. After adjusting for confounding variables by multiple logistic regression analysis, hepatitis B vaccine performance showed significantly higher rate as the perception of disease seriousness increased(OR: 1.08, 95% CI: $1.03{\sim}1.14$) and in the group contacted with TV or radio information about hepatitis compared with non-contact. The group who experienced hepatitis among family or friends showed significantly higher hepatitis B vaccination performance rate compared with non-experienced. Conclusion: These results suggested that hepatitis B vaccine performance was related with health belief including hepatitis susceptibility, disease seriousness perception, acquisition of information through TV or radio and indirect hepatitis experience from family or friends.

This paper is to study for causality validation of relation of the repair justice and repair satisfaction, relation between repair satisfaction and re-purchasing with South Korea's most important express service users. Through this research, we would like to confirm to seriousness of the failure express service and effects of controlling effectively adjust in relation between repair impartiality and satisfaction of repairs. The results of the study show as below. First, the result shows the justice outcome in express service, interaction justice, outcome justice in the relation of satisfaction with repair have regardful effects to the satisfaction of repair. This result explains that interaction justice has a positive influence. Second, in the relations between the procedural justice in express service and the satisfaction of repair, it is presented that the procedural justice has not regardful effects and results show differences from other leading researches. This result explains that procedural justice has not a positive influence. Third, as analyzing seriousness of the failure express service, controlling regulation effect in the relation of repair justice and repair satisfaction, seriousness of interaction and controlling regulation effect are not regardful effect in this relationship. These results are explained that the seriousness or controlling of the failure express service have not a positive influence to the relation of repair justice and repair satisfaction. Finally, in the relation between repair satisfaction and the intention to use again, repair satisfaction has a regardful effect to intention to use again. This result explained that it has positive influence to repair satisfaction and the intention to use again.

This descriptive correlational study was conducted to identify the factors influencing the uncertainty of patients undergoing chemotherapy for lung neoplasms. One hundred and eleven patients were recruited from the chemotherapy clinic of a university hospital. Data were collected from July 25 to December 31, 2014, and analyzed by descriptive statistics, the t-test, ANOVA, the Scheffe test, Pearson's product moment correlation coefficients and multiple regression analysis with SPSS for Windows Version 18.0. The mean score of the uncertainty of the patients undergoing chemotherapy for lung neoplasms was 2.61(${\pm}0.46$), which was higher than that of the patients with other diseases. The uncertainty was positively correlated with the seriousness of the illness (r=.74, p<.01) and consistency of the symptoms (r=.27, p<.01). Multiple regression analysis showed that the (main) factor influencing the uncertainty was the seriousness of the illness, which explained 54% of the uncertainty of the patients undergoing chemotherapy for lung neoplasms. As a result, nursing interventions are needed to reduce the uncertainty of lung neoplasm patients who are receiving chemotherapy. The seriousness of the illness should be considered when developing nursing interventions to reduce the uncertainty of lung neoplasm patients.

Purpose: This study investigated the level of adherence to vestibular rehabilitation exercise program(VREP) and evaluated how health belief model (HBM) variables are related with adherence to VREP in patients with dizziness. Methods: The data were collected from 150 individuals, who agreed to participate in the study between December, 2012 and May, 2013. Adherence to VREP, severity of dizziness, health belief variables (health belief scale) and self-efficacy (self-efficacy scale) were measured. Results: The result of this study showed poor adherence to VREP. The mean adherence score to VREP was $2.11{\pm}1.05$ (1-5). In multivariate analysis, severity of dizziness (p<.001), taking sedative medication (p<.001), high self-efficacy (p<.001), high perceived seriousness (p=.019) & benefit (p=.036) were independent predicting factors explaining 57.7% of adherence to VREP. Conclusion: Adherence to VREP was poor among these patients. To improve the patient's adherence to VREP, strategies to increase perceived seriousness, benefit, or self-efficacy and to decrease barriers are urgently needed.
