In this paper, the study model, which presents the patterns of how the changing mechanisms are adopted to the changing stages of smoking cessation, was developed by modifying the integrative model of Prochaska et al. (1983) with including seven changing mechanisms which were identified by Oh and Kim(1996). Then the developed study model was exploratively tested with 155 University student between 20 and 29 years of age as subjects. According to the study results. among the five mechanisms. which are significant in explaining the differences between stages. DUNCAN post-comparison showed that the least applied ones were Stimulus Control, Self Determinism, Cognitive Restructuring in the precomplation stage, and Reinforcement and Dramatic Relief. in the relapsed stage. In the comtemplation stage. it was observed that Dramatic Relief is used most frequently and that the other two mechanisms, Information Management and Cognitive Restructuring, showed different results from those inferred in the study hypothesis. In the case of Information Management, it was excluded from the analysis it was not included in explaining significant difference among changing stages, but Cognitive Reconstruction turns out to be a more frequently used mechanism in the action stage rather than in the comtemplation stage. Helping Relationship was also excluded in the post-comparison analysis since it was not included in explaining significant difference among changing stages and Reinforcement was a more frequently used mechanisms in the comtemplation stage. Stimulus Control turns out to be the connecting mechanism which was most frequently used in both the contemplation and action stages. Self Determination was most frequently used in the action stage rather than in both the comtemplation stage and action stage, differing from the presumption of the model. Lastly, subjects in the relapsed stage were utilizing Stimulus Control and Self Determination at the same level as subjects in the precontemplation stage. and the utilization of both Reinformcement and Dramatic Relief was lower than that of the precomtemplation stage, that is, at the lowest level. Only Cognitive Restructuring was used of the same level as the comtemplation stage. The relapsed stage in this study did not represent the preparation for action stage as presumed in the model of Prochaska et. al. (1983) but did show a pattern similar to the initial stage of smoking cessation. However, since this interpretation about the relapser was based on only a small number of relapsers(n=5), this conclusion may not be reliable.

Purpose: This study was conducted to test a path model for the factors related to undergraduate nursing students' clinical practicum stress, based on Lazarus and Folkman's stress-coping model. Methods: This study utilized a path analysis design. A total of 235 undergraduate nursing students participated in this study. The variables in the hypothetical path model consisted of clinical practicum, emotional intelligence, self-efficacy, Nun-chi, and nursing professionalism. We tested the fit of the hypothetical path model using SPSS/WIN 23.0 and AMOS 22.0. Results: The final model fit demonstrated a satisfactory statistical acceptance level: goodness-of-fit-index=.98, adjusted goodness-of-fit-index=.91, comparative fit index=.98, normed fit index=.95, Tucker-Lewis index=.92, and root mean square error of approximation=.06. Self-efficacy (${\beta}=-.22$, p=.003) and Nun-chi behavior (${\beta}=-.17$, p=.024) were reported as significant factors affecting clinical practicum stress, explaining 10.2% of the variance. Nursing professionalism (${\beta}=.20$, p=.006) and self-efficacy (${\beta}=.45$, p<.001) had direct effects on emotional intelligence, explaining 45.9% of the variance. Self-efficacy had indirect effects on Nun-chi understanding (${\beta}=.20$, p<.001) and Nun-chi behavior (${\beta}=.09$, p=.005) through emotional intelligence. Nursing professionalism had indirect effects on Nun-chi understanding (${\beta}=.09$, p=.005) and Nun-chi behavior (${\beta}=.09$, p=.005) through emotional intelligence. The variables for self-efficacy and nursing professionalism explained 29.1% of the Nun-chi understanding and 18.2% of the Nun-chi behavior, respectively. Conclusion: In undergraduate nursing education, it is important to identify and manage factors that affect clinical practicum stress. The findings of this study emphasize the importance of Nun-chi, self-efficacy, emotional intelligence, and nursing professionalism in the development of an educational strategy for undergraduate nursing students.

This study empirically investigates the international transmission of China's uncertainty shocks. It estimates a time-varying parameter Bayesian global structural vector autoregressive model (TVP-BGVAR) using time series data for 33 countries to evaluate heterogeneous international linkage across countries and time. Uncertainty shocks are identified via sign restrictions. The empirical results reveal that an increase in uncertainty in China negatively affects the global economy, but those effects significantly vary over time. The effects of China's uncertainty shocks on the global economy have been significantly altered by China's WTO accession, the global financial crisis, and the recent US-China trade conflict. Furthermore, the effects of China's uncertainty shocks, typically on inflation, differ significantly across countries. Moreover, Trade openness appears crucial in explaining heterogeneous GDP responses across countries, whereas the international dimension of monetary policy appears to be important in explaining heterogeneous inflation responses across countries.

Purpose: The purpose of this study was to determine handwashing-related factors in nurses. Specific purposes of this study were to examine 1) the applicability of the hypothetical model constructed for this study, on the basis of Theory of Planned Behavior(TPB), and 2) relationships between handwashing practice and other variables such as age, career, level of education, and level of recognition about handwashing. Method: Data were collected from 187 nurses in one university hospital in Kyung-Ki province. Result: The hypothetical model based on TPB was revealed applicable, but the degree of the variance explaining handwashing practice was small(26%). Perceived behavioral control(PBC) was the most strong variable explaining handwashing practice, and intention didn't have a significant effect on handwashing practice. Norm and PBC had significant effects on intention, but attitude was not a significant factor of intention. Age, career, and the level of awareness of handwashing practice were significantly related to handwashing practice. Conclusion: The result of this study suggests that we should focus on perceived behavioral control, awareness of handwashing practice and subjective norm about handwashing practice to increase the level of nurses' handwashing practice.

Purpose: The purpose of this study was to determine the relationship among concepts of the salutogenic model - sense of coherence, occupational stress, and health status in clinical nurses. Methods: Participants were recruited from a hospital in Seoul using a stratified random sampling. A total of 349 nurses participated in the study and data were collected using a self-administered questionnaire. The structural equation model was used to assess the relationships among the variables. Results: The results of the study showed that occupational stress and health behavior were significant factors, directly explaining the health status of nurses. Factors explaining occupational stress were: sense of coherence, and social support. Sense of coherence showed higher effects on occupational stress than those of social support. Sense of coherence and the work conditions (work experience and shift work) of nurses had a significant and direct effect on health behavior. Sense of coherence and social support had a significant and indirect effect on health status through occupational stress and health behavior. Conclusion: Strategies to enhance sense of coherence and social support are necessary for successful health promotion programs for nurses.

The disconfirmation paradigm is the earliest researched and the most deeply researched of all the paradigms in marketing. Disconfirmation paradigm deals with the influence of expectation, perceived product performance, and the discord between the two on consumer satisfaction. The GAP-Model is based on the disconfirmation paradigm that tries to understand the effect of the gap between before purchase expectations and after purchase perceptions of the product performance on dependent variables such as customer satisfaction. The purpose of this research is to test whether regression coefficients of a P-Model(performance only model), an E-Model(expectation only model) and GAP(P-E)-Model are equivalent in explaining service value and loyalty. The Chow's F-Test is used to test the excellence of the 3 models. As a result of comparison and analysis, P-Model showed more excellence of service value and loyalty than E-Model or GAP-Model.

Isolation-with-migration (IM) models have become popular for explaining population divergence in the presence of migrations. Bayesian methods are commonly used to estimate IM models, but they are limited to small data analysis or simple model inference. Recently three methods, IMa3, MIST, and AIM, resolved these limitations. Here, we describe the major problems addressed by these three software and compare differences among their inference methods, despite their use of the same standard likelihood function.

In this paper, we present the analytical models for substrate current and gate current of stressed SC-PMOSFET using the change of the lateral electric field distribution due to the trapped electron. Calculated Isub and Ig of stressed SC-PMOSFET agree with experimental data. Our model can be very useful explaining the logarithmic time dependence of Isub and Ig. and also the trapped electron distribution.

This study deals with the concept of Microcomputer Playfulness(MCP), Even though MCP was introduced recently in the MIS research, the concept is expected and empirically supported to be significant in explaining information technology adoption and usage. Based on the Technology Acceptance Model(TAM), this study presented a revised model to explain individual PC use and explored the role of MCP in PC use. The results showed that MCP has a direct influence on PC use rather than a mediator between Self-efficacy and PC use, and that MCP is a better predictor of PC use than Computer Anxiety.

The purpose of this study was to clarify the dynamic relationships among risk factors of arteriosclerosis and to develop and examine a model which could explain this relationship clearly. Data were collected from medical records of 400 male clients who visited a university hospital located in Inchon for physical examinations, from May 1996 to December 1996. Data were analyzed using the LISREL (Linear Structural Relationship) 8 program. To test the fitness of the hypothesized model, chi-square, RMSR (root mean square residual), GFI (goodness of fit index), CN (critical number) and Q-plot were used. Most of the fitness measurements, except the chi-square showed that the hypothesized model complimented the real data. According to the results, there were trends that obesity and hyperlipidemia were prevalent in heavier smokers, higher alcohol intakers, and groups who excercised less. Also, hypertension was more prevalent in older age, higher alcohol intaker, and higher serum lipid level groups. In contrast to the hypothesis, alcohol intake did not significantly affect serum lipid levels. This might be due to the serum lipid measurements (total cholesterol and trigryceride) used in this study to estimate hyperlipidemia. The direct effect of smoking on hypertension was not significant. However, the total effect of smoking on the hypertension was significant since indirect effects of smoking on hypertension, such as obesity and hyperlipidemia, were significant. The total effect of obesity on hypertension was significant since the indirect effect of obesity on hypertension via hyperlipidemia was significant, although the direct effect of smoking on hypertension was not significant. The degree of explaining hyperlipidemia with smoking, exercise, and obesity was high (60%), however, the degree of explaining obesity with age, smoking, alcohol intake, and exercise was very low (7%). On the basis of these results, high risk factors of arteriosclerosis such as hypertension, hyperlipidemia, or obesity are either directly or indirectly correlated each other. Therefore, it is difficult to predict outcomes for increasing or decreasing the risk factors by simply modulating a factor. Smoking, alcohol, and exercise both directly and indirectly affected major risk factors of arteriosclerosis. Therefore, correcting these variables is required to decrease risk factors. Finally, the relationship among other risk factors which have been known to be related with arteriosclerosis (diet, stress or hereditary) should be clarified in further studies.
