The purpose of this study was to investigate the salt-related dietary behaviors according to the stage of change model in middle school students from the Gyeongsangbuk-do area. Data were collected from, a total of 253 male and 210 female middle school students through. Self-reporting questionnaire. By stage of salt-related dietary behaviors, the 'Pre-contemplation stage' was comprised of 57.3%, the 'Contemplation stage' of 12.2%, the 'Preparation stage' of 7.4% and the 'Action stage' of 23.2% of students. There were significant differences in the stage of change according to the experience with salt-related nutrition education (p<0.05), wherein differences according to gender and parent's education were not observed. In the salt-related dietary behaviors, there were significant differences according to gender (p<0.05), pocket money (p<0.01), and the stage of change (p<0.001). Males had higher salt-related dietary behavior scores than females, while students who had more pocket money also had higher scores, and the action group had lower scores than the other groups. Among the 10 items of salt-related dietary behaviors, only 4 showed above the average score (2.92/5.00), including behaviors of liking kimchi, completely consuming snacks and instant foods, and drinking the broth of soups. The salt-related dietary score of males was higher than females, while the action group's score was lower than the other stages.

Purpose: The study was performed to identify the process of change, decisional balance and self-efficacy corresponding to the stage of exercise behavior change based on a Transtheoretical Model in middle aged women. Method: The subjects consisted of 317 women by convenience sampling residing in city B. The collected data were analyzed using one-way ANOVA, Scheffe test, and Discriminant analysis by SPSS/WIN program. Result: The subjects were distributed in each stage of change of exercise behaviors: 53 subjects (16.7%) in the precontemplation stage, 86 subjects (27.1%) in the contemplation stage, 88 subjects (27.8%) in the preparation stage, 51 subjects (16.1%) in the action stage and 39 subjects(12.3%) in the maintenance stage. Analysis of variance showed that consciousness raising (F=24.96, p=.00), environmental reevaluation (F=7.l3, p=.00), self reevaluation (F=19.47, p=.00), dramatic relief (F=15.22, p=.00), social liberation (F=4.26, p=.00), counter conditioning (F=26.44, p=.00), a helping relationship (F=13.l7, p=.00), reinforcement management (F=21.25, p=.00), self liberation (F=27.70, p=.00), stimulus control (F=13.49, p=.00), pros (F=14.40, p=.00) and self-efficacy (F=39.9l, p=.00) were significantly associated with the stages of change of exercise behaviors. Through discriminant analysis, it was found that ‘stimulus control’ was the most influential variable in discriminating the five stages of change. Conclusion: This study can provide the basis of a staged matching exercise program using TTM for more effective and useful intervention.

Purpose: This study was carried outto compare dietary self-efficacy, obesity stress, and obesity-related quality of life (OQOL) according to BMI and stages of change in vegetable consumption. Methods: A convenience sample of 326 nursing students agreed to complete a questionnaire. Data were collected from October 7 to October 18, 2013. Results: Obesity stress and obesity-related quality of life were significantly different according to BMI. Dietary self-efficacy showed a significant difference between the pre-contemplation/contemplation stage, preparation stage, and action/maintenance stage (F=50.18, p<.001). With obesity stress, there was a significant difference between the PC/C, P, and A/M stages (F=17.63, p<.001). Dietary self-efficacy had a positive correlation with OQOL (r=.11, p<.001) and a negative correlation with obesity stress (r=-.14, p=.012). And obesity stress had a negative correlation with OQOL (r=-.45, p<.001). Conclusion: These findings emphasize that nutritional-intervention programs for changes in behavior during the PC/C and P stages of change in vegetable consumption need to develop strategies to enhance dietary self-efficacy for nursing students.

The prevalence of obesity is increasing worldwide and has become a serious epidemic health problem. We developed the 'Change 10 Habits' educational program based on obesity treatment and dietary guidelines and examined its effects on customized nutrition education in mildly obese adults. The study was approved by the Institutional Review Board. Study subjects were excluded if they had several major diseases, if had consumed an anti-obesity drug, or if they practiced an obesity-related program within 30 days. The subjects (n=87, $25{\leq}BMI$ <30) were each exposed to the customized nutrition education program with four lessons according to the stage of the transtheoretical model (TTM). The stage-matched program was administered for 12 weeks and was run by a clinical dietitian. Overall, subjects who were in the precontemplation/contemplation stage at baseline made progress in the preparation and action/maintenance stage after 12 weeks (P<0.05). For 'Alcohol is consumed, up to 2 drinks per day', the proportion of subjects who belonged in the action/maintenance stage increased from 34.5% to 49.4% at 12 weeks. In addition, scores of all items significantly increased after the program (P<0.05). 'Chew more than 10 times and eat slowly' score significantly increased from $3.9{\pm}2.4$ to $5.8{\pm}2.3$ (P<0.05). In conclusion, behavioral stage-matched nutrition education using the 'Change 10 Habits' program was effective in improving eating behaviors and enhancing healthy lifestyles in mildly obese adults.

Purpose: The purpose of this study was to review behavior change theories in terms of important variables, concept definitions, and applicability to diabetes self-management behavior. Methods: Six behavior change theories (the Transtheoretical Model, the Health Belief Model, the Theory of Reasoned Action, the Theory of Planned Behavior, Social cognitive theory, and Information-Motivation-Behavioral skills Model) were reviewed which were applied in diabetes self-management interventions. Results: The five key concepts from the five non-stage behavior change theories were delineated. Based on the key concepts, a theoretical framework was formulated as the explanatory model of diabetes self-management behaviors. The four major concepts in Information-Motivation- Behavioral skills Model were included. The cognitive arm of the proposed theoretical framework included constructs related to diabetes knowledge, motivation (beliefs, attitude, social norm), self-efficacy, and intention. Conclusion: The theoretical framework described here includes the key factors of successful diabetes self- management intervention. However, the concept of motivation needs further exploration and clarification for operationalization.

We develop a method to analyze dynamic behavior off multi-stage gear train system. The example system consists of three shafts supported by ball bearings at the ends of them and two pairs of spur gear set. For exact analysis, the meshing tooth pair of gear set is modeled as spring and damper having time-dependent meshing stiffness and damping. The bearing is modeled as spring. The result of this analysis is compared to that of other model having mean mesh stiffness. The effect of the excitation force by the unbalance off rotor off motor is also analyzed. Finally, the change ova natural frequency of the whole system due to the change of an angle between three shafts is compared in each case, and from this analysis, the avoiding angle for design is advised.

Purpose: This study was conducted to examine effects of a small group-based cardiocerebrovascular disease (CVD) prevention education program on knowledge, stage of change and health behavior among male bus drivers with CVD risk factors. Methods: A non-equivalent control group pretest-posttest design was used. Participants were 68 male bus drivers recruited from two urban bus companies. Participants from the two groups were selected by matching age, education and risk factors. Experimental group (n=34) received a small group-based CVD prevention education program 8 times over 6 weeks and 3 times through telephone interviews at 2-week intervals. Data were collected between December, 2010 and March, 2011, and were analyzed using chi-square test, t-test, and repeated measure analysis of variance with SPSS/Win18.0. Results: Experimental group showed significantly higher scores in CVD prevention knowledge (p<.001) and health behavior (p<.001) at 6 and 12 weeks after intervention. Participants in pre-contemplation and contemplation stages made progress to contemplation and action. This was significantly better at 6 and 12 weeks after intervention (p<.001). Conclusion: Results suggest that small group-based education programs for CVD prevention are effective in increasing knowledge, stage of change, and health behavior to prevent CVD among male bus drivers with CVD risk.

Purpose: The purpose of this study is to find taxi drivers' smoking behavior, self-efficacy and expectation level of success in smoking cessation. It will provide useful information for developing nursing interventions in health promotion programs. Method: The subjects of this study were 271 taxi drivers in Seoul and its metropolitan area. Data were collected using a self-reported questionnaire asking smoking history, smoking behaviors, health problem, stages of change for smoking cessation, self-efficacy and the expectation level of success in smoking cessation. Data were analyzed through descriptive statistics. Pearson's correlation, Mann-Whitney U test, Kruskal-Wallis test and Cronbach's a. Results: Of the taxi drivers, 83.8% were current smokers. Stages of change were as follows: 45.8% were in the precontemplation stage, 26.2% in the contemplation stage, 13.7% in the maintenance stage, 12.2% in the preparation stage and 1.5% in the action stage. In addition. 20.3% of the subjects reported health problems such as hypertension, heart disease, diabetes mellitus and respiratory disease. The expectation level of success in smoking cessation was positively related with self-efficacy. There were statistically significant differences in the expectation level of success in smoking cessation according to the number of cigarettes per day and nicotine dependency. In addition. there were statistically significant differences in self-efficacy according to the number of cigarettes per day, duration of smoking (years) and nicotine dependency. Conclusion: The results of this study suggest that taxi drivers' health problems and smoking rate were serious. Therefore more systematic health promotion programs for smoking cessation should be developed and executed by health care specialists at individual taxi companies.
