Purpose: The purpose of this study was to construct and test a hypothetical model of self-management in patients with hemodialysis based on the Self-Regulation Model and resource-coping perspective. Methods: Data were collected from 215 adults receiving hemodialysis in 17 local clinics and one tertiary hospital in 2016. The Hemodialysis Self-management Instrument, the Revised Illness Perception Questionnaire, Herth Hope Index and Multidimensional Scale of Perceived Social Support were used. The exogenous variable was social context; the endogenous variables were cognitive illness representation, hope, self-management behavior, and illness outcome. For data analysis, descriptive statistics, Pearson correlation analysis, factor analysis, and structural equation modeling were performed. Results: The hypothetical model with six paths showed a good fitness to the empirical data: GFI=.96, AGFI=.90, CFI=.95, RMSEA=.08, SRMR=.04. The factors that had an influence on self-management behavior were social context (${\beta}=.84$), hope and cognitive illness representation (${\beta}=.37$ and ${\beta}=.27$) explaining 92.4% of the variance. Self-management behavior mediated the relationship between psychosocial coping resources and illness outcome. Conclusion: This research specifies a more complete spectrum of the self-management process. It is important to recognize the array of clinical resources available to support patients' self-management. Healthcare providers can facilitate self-management through collaborative care and understanding the ideas and emotions that each patient has about the illness, and ultimately improve the health outcomes. This framework can be used to guide self-management intervention development and assure effective clinical assessment.

The aim of this study was to determine the extent to which sociodemographic and health related life-style variables explain body weight distribution and to understand weight contol behavior. To study this study 298 students were selected, it was consisted of obesity group(101) and control group(197). The average age of subjects was 14.2 and the prevalence of obesity was 2-3 per class as 5.6% among 1,793. 71% among same subject was showed higher weight pattern than last one year, ovesity group which was obesity both in 93 and 94 was 34%. Correlation between body weight(under weight/obesity) and independent variables including sociodemographic factor and health- related life style tested through Multiple Classification Analysis was very significant, explained 36% of the total variance. Sociodemografic and hereditary factors such as education level, age of father and physical features of parents, life style factors as exercise preference and perceived health status showed highly contribution to body weight. Concretely, there were showed a higher obesity prevalence tendency when education level and age of father was high, physical features of parents was obesity. In otherwise, there were showed a higher underweight prevalence tendency when education level and age of father was low. Experience rates of weight control was 53% generally, 84% in obesity group, and 11% in underweight group. There were utilized weight control behaviors through diet method mainly in obesity group, diet and exercise methods in underweight group. There were showed that underweight group are prefer exercise to obesity group. Conclusionally, These findings suggest that education, age, physical features of parents, exercise preference and perceived health status is important factors related to body weight among middle school girls. Therefore, there will be considered as valuable factors when we practice health education and consultation related to body weight. Furthermore it is necessary to provide of various informations about weight control and to develop systematic weight control program.

Purpose: This study aimed to identify the degree of accident prevention behavior, self-esteem, self-regulation ability, and social support among middle-school students, and investigate factors influencing their practice of accident prevention behaviors. Methods: The participants were 174 students from two middle schools located in J city. Data were collected from December 28, 2017 to February 9, 2018 using self-reported questionnaires. Results: The mean score were $3.08{\pm}0.37$ of 4 for practice of accident prevention behaviors, $3.07{\pm}0.57$ of 4 for self-esteem, $3.69{\pm}0.48$ of 5 for self-regulation ability, and $3.38{\m}0.75$ of 5 for social support. Positive correlations were found among self-regulation ability, self-esteem, social support, and practice of accident prevention behaviors. The factors influencing the practice of accident prevention behaviors were personality (being 'haste') (${\beta}=-.20$, p=.003), self-regulation ability (${\beta}=.48$, p<.001), and social support (${\beta}=.23$, p<.001). These factors explained 39.0% of the variance in practice of accident prevention behaviors. Conclusion: It was found that the middle-school students engaged in prevention behavior to an extent that was insufficient to prevent accidents. Therefore, it is necessary to develop intervention strategies to improve the practice of accident prevention behavior among middle-school students, considering self-regulation ability, social support, and personality, which affect the practice of accident prevention behaviors.
