Purpose The purpose of this study is to investigate the reason why smartphone users do not use mobile banking based on Status Quo Bias and to find out whether there is a difference between passive resistance and active resistance. Design/methodology/approach This study made a design of the research model based on Status Quo Bias. SPSS 23.0 and SmartPLS 2.0 were used for the analysis. Multiple group analysis was performed to identify differences between groups. Findings According to the empirical analysis result, this study confirmed that inertia and perceived risk affected smartphone users who do not use mobile banking. According to the type of resistance, the active resistance group(64.2%) was more than the passive resistance group(35.8%), and it was confirmed that there was a difference in the reasons for not using mobile banking between passive and active resistance group. That is, the greatest difference between passive and active resistance groups was found to be perceived risk, which is an assessment of risk.

Purpose - The purpose of this research is to examine the differences and interaction effects of perceived risk and product attitudes between Korea and Thailand consumers in accordance with price discount and product types. Research design, data, and methodology - A questionnaire survey was conducted in Korea and Thailand. There were a total of 327questionnaires received, and 322 of them were valid. Respondents consisted of 163 Koreans and 159 Thai consumers. Each question is measured in a Likert-type five-point scale. To verify the difference and interaction effects of perceived risk and product attitudes, ANOVA analysis was carried out. Results - This research found that the perceived risk of Thailand consumers in accordance with price discount and product types is confirmed to be larger than Korean consumers. The difference of product attitudes of Thailand consumers is higher than those of Korean consumers. Thus, product attitudes in accordance with country type and price discount types are verified with the interaction effect. The difference of product attitudes in accordance with price discount type and product types are not founded. The main effect was not verified. Conclusions - The finding of this study can be used as useful information to Korean and Thai retailers looking to enter the global market.

Background: This study analyzed the effect of applying the diagnosis-related group (DRG)-based payment system, which was implemented in July 2012 for hospitals and clinics nationwide, on the cesarean section rate. Methods: The subjects of the study were divided into new groups that participated in the payment system after July 2012 and maintenance groups that participated in the payment system before July 2012. As an analysis method, a difference-in-difference analysis, which is a quasi-experimental design, was used. The risk-adjusted cesarean section rate was used as a dependent variable. Results: Seven risk factors (malpresentation of fetus, eclampsia, multiple pregnancies, problems in the placenta, previous Cesarean section, cephalopelvic disproportion, problems in amniotic fluid) were included in the final risk-adjustment model, and found to have a statistically significant relationship with the cesarean section rate. Results showed that the risk-adjusted cesarean section rate increased significantly in new groups after the application of the DRG-based payment system. Conclusion: Study results provided policy implications for the reorganization of the DRG-based system should that reflects the demands of obstetricians, such as organizing a consultative body with obstetricians and establishing a reasonable fee.

There have been various studies on measurements of flood risk and forecasting models. For river and dam region, PDF and FVI has been proposed for measurement of flood risk and regression models have been applied for forecasting model. For Bo region unlikely river or dam region, flood risk would unexpectedly increase due to outgoing water to keep water amount under the designated risk level even the drain system could hardly manage the water amount. GFI and general linear model was proposed for flood risk measurement and forecasting model. In this paper, FVI with the consideration of duration on GFI was proposed for flood risk measurement at Bo region. General linear model was applied to the empirical data from Bo region of Nadong river to derive the forecasting model of FVI at three different values of Base High Level, 2m, 2.5m and 3m. The significant predictor variables on the target variable, FVI were as follows: ground water level based on sea level with negative effect, difference between ground altitude of ground water and river level with negative effect, and difference between ground water level and river level after Bo water being filled with positive sign for quantitative variables. And for qualitative variable, effective soil depth and ground soil type were significant for FVI.

Usually, a risk can be expressed as a product of likelihood and consequence of a hazard factor. Therefore, conventional risk assessment is carried out by frequency analysis and severity analysis, in turns. However, it is well known that intuitive thinking is another excellent way of thinking of human beings. This study aimed to confirm whether there exist any difference in risk assessment results derived by two different procedures - intuitive and analytical. Thus, the present study showed 10 different illustrations to 30 undergraduate students. Their responses were organized as fuzzy membership functions, and summarized as risk assessments, and compared. The results were also verified with the help of statistical hypothesis testing, which showed no significant difference. On the contrary, however, similarity measure used in fuzzy set theory was not credible as anticipated. Many cases failed to satisfy statistical hypothesis even with similarity measure higher than 0.60 so that only a trend could be accepted. In addition, a subject showed a somewhat consistent logical discrepancy in his response, which implied the necessity of sincere analysis in fuzzy formulations.

Objectives : The purpose of this study was to evaluate the blood flow using doppler ultrasound of the MCA, ACA, PCA, BA, ICA in the patients with risk factor for stroke. Methods : 110 patients with risk factor for stroke were selected who had hypertension, diabetes mellitus, hyperlipidemia, or heart disease, as well as 89 healthy adults who did not have any symptoms of those diseases. To evaluate the blood flow, the Vs and Vm of the MCA, ACA, PCA, BA, and ICA in the two groups were measured. Result : In normal healthy adults, subjects showed a decrease in the Vs and Vm: with advancing in age, there was a significant difference in the Vs of MCA, PCA, BA, and ICA. There was a significant difference in the Vm of MCA, PCA, BA, and ICA. In normal healthy adults, females showed high velocities in all examined vessels. There was a significant difference in the Vs of BA. There was a significant difference in the Vm of BA, and ICA. There was a decrease in the Vs, and Vm of all examined vessels of patients with risk factors for stroke in comparison with normal healthy adults. There was no significant difference in the Vs. There was a significant difference in the Vm of MCA, ACA, and PCA. Results were the same between patients aged under 50 and total patients in the Vs and Vm of examined vessels. There were differences between patients aged over 50 and total patients in the Vs of MCA, PCA, BA and for patients aged over 50; patients with risk factor for stroke who had hypertension, diabetes mellitus, hyperlipidemia, or heat disease has higher Vs than healthy adults. Conclusions : There was a significant difference in the blood flow velocity between patients with risk factors for stroke and healthy adults. However, this result was different from results of comparison of TCD findings between patients and healthy individuals by age. Therefore, more detailed studies about aged patients are needed.
