Purpose: This study examined the influencing factors from the Transtheoretical Model on the stage of change in the self-management behaviors, i.e. regular physical activity and diet, among community-residing adults with hypertension in a rural area. Methods: With a cross-sectional descriptive design, 134 adults who had registered and received a prescription for hypertension medication from a public health center in W city were recruited using convenient sampling. The instrument was an interviewer-administered questionnaire on the stage of change, process of change, self-efficacy, and decisional balance of physical activity and diet. The data were analyzed using descriptive statistics, 2-sample t-test, ${\chi}^2$ test, and logistic regression. Results: The results revealed significant differences in the process of change, self-efficacy, and decisional balance of physical activity and diet between those who were in the pre-execution stage (precontemplation, contemplation, preparation) and those who were in the execution stage (action and maintenance). Logistic regression showed that consciousness raising and self-efficacy were significant predictors of the execution stage in physical activity, and self-reevaluation, social liberation and self-efficacy were significant predictors in the diet. Conclusion: The relevant processes of change, differentiated according to the stage of change, along with self-efficacy, should be addressed to enhance the execution of self-management behaviors among hypertensive adults residing in the community.

Purpose: There is little known about teachers' self-efficacy in health teachers even though over 75% of Korean health teachers have offered school health education. The purpose of this study was to examine factors related to teachers' self-efficacy in Korean health teachers. Methods: Data were collected from school nurses from 474 schools such as 236 elementary schools, 140 middle schools and 98 high schools in Seoul with the stratified random sampling method. The associations among school characteristics, health teachers' characteristics, and teachers' self-efficacy were examined by ANOVA (Anlaysis of variable). To identify the possible predictors of teachers' self-efficacy, ANCOVA (Analysis of covariance) was performed. Results: Two factors, school stage (elementary, middle or high schools) and types of school (public or private school), were significantly related to teachers' self-efficacy. Teachers' self-efficacy of health teachers in elementary schools was significantly higher than that in middle and high schools. Health teachers in private school had significantly higher teaching self-efficacy than ones in public school. Conclusion: Given the fact that health teachers in elementary and private school had higher teachers' self-efficacy, an intervention to strengthen teachers' self-efficacy of health teachers in middle and high schools as well as ones in public school is required to help children and adolescents learn good health behaviors.

Objectives: The purpose of this study is to investigate the influencing factors on oral health related self-efficacy and social support in high school students. Methods: The subjects were 750 high school students in Jeonbuk by convenience sampling. A self-reported questionnaire was completed from April 3 to June 4, 2013. Except incomplete answers, 589 data were analyzed using SPSS 18.0 program for t-test, ANOVA, post hoc Scheffe test, and multiple regression analysis. The questionnaire consisted 6 questions of general characteristics of the subjects, 8 questions of oral health related self-efficacy, and 8 questions of oral health related social support. The instrument for self-efficacy was developed by Sherer and Maddux and measured by Likert 4 scale. Interpersonal Support Evaluation List(ISEL) was developed by Cohen and Hoberman and revised by Suh as oral health related social support in high school students, and measured by Liker 4 scale. Cronbach's alpha in self-efficacy was 0.768 and that in social support was 0.772. Results: The good oral health behavior in the high school students was closely related ro self-efficacy and social support. Higher self-efficacy and social support could make the students practice good oral behavior. Conclusions: Higher self-efficacy and social support can influence on the good oral health behavior in high school students. So it is very important to provide the continuous oral health education that can enhance self-efficacy and health promotion.

Objectives: The present study proposed to evaluate 1st-month and 3rd-month health status, depression, self-efficacy and medical expenses of a community-based health promotive self-management program for old Koreans. Method: Participants in the CDSMP were selected from elders in a community health center through convenient sampling. The program included a 3-hour session per week for 14 weeks. Outcomes of evaluation in the 1st month and the 3rd month included modified Self-rated Health Status Scale, Center for Epidemiologic Studies Short Depression Scale, Self-Efficacy for Managing Chronic Disease 6-item Scale, and 1-item Medical Expenses Scale. Results: Self-rate health scores increased significantly just after the intervention (16.22), in the 1st month (17.57) and in the 3rd month (19.04) (x2=32.06. p=.000); Depression scores (reversed) also increased significantly just after the intervention (6.04), in the 1st month (7.75) and in the 3rd month (8.39) ( $x^2=29.92$. p=.000); Self-efficacy score increased significantly just after intervention (12.87) but it decreased in the 1st month (12.73) and in the 3rd month (12.04). But all of the three scores were still higher than those before the intervention (8.65) ($x^2=32.42$. p=.000): Medical expense score decreased at the end of the intervention (1.57) but the cost score increased in the 1st month (2.48) and in the 3rd month (2.39) ($x^2$=7.81. p=.050). Conclusion: CDSMP is effective in increasing self-rate health and self-efficacy and in decreasing depression in the Korean elderly. However, no significant effect of the program was observed in decreasing the medical cost of the Korean elderly.

Background: As self-employed workers are vulnerable to health problems, this study aimed to analyze mental health problems and sleep disturbances among self-employed workers compared with paid workers in Korea. Methods: A total of 34,750 workers (23,938 paid workers and 10,812 self-employed workers) were analyzed from the fifth Korean Working Condition Survey, which included 50,205 households collected by stratified sampling in 2017. To compare mental health problems and sleep disturbance among self-employed workers and paid workers, multivariate logistic regression analyses were performed. Results: The odds ratio in self-employed workers compared with paid workers was 1.25 (95% confidence interval [CI]: 1.09-1.42) for anxiety, 1.11 (95% CI: 1.04-1.17) for overall fatigue, 1.11 (95% CI: 1.04-1.20) for difficulty falling asleep, 1.10 (95% CI: 1.02-1.18) for difficulty maintaining sleep and 1.24 (95% CI: 1.16-1.32) for extreme fatigue after waking up. Conclusions: Self-employed workers in Korea have a higher risk of self-reported mental health problems and sleep disturbances than paid workers. Further studies with a longitudinal design and structured evaluation are required to investigate the causal relationship between health problems and self-employment.

In the conventional interchannel interference self-cancellation (ICI-SC) schemes, the length of sampling window is the same as the symbol length of orthogonal frequency division multiplexing (OFDM). Thus, the number of complex operations to compute the interference coefficient of each subchannel is significantly increased. To solve this problem, we present an approximated mathematical model for the coefficients of ICI-SC schemes. Based on the proposed approximation, we analyze mean squared error (MSE) and computational complexity of the ICI-SC schemes with the length of sampling window. As a result, the presented approximation has an error of less than 0.01% on the MSE compared to the original equation. When the number of subchannels is 1024, the number of complex computations for the interference coefficients is reduced by 98% or more. Since the computational complexity can be remarkably reduced without sacrificing the self-cancellation capability, it is considered that the proposed approximation is very useful to develop an algorithm for the ICI-SC scheme.

The main aim of the paper is to provide an empirical analysis on patient satisfaction as an indicator of service quality in Malaysian public hospitals. Self-administered questionnaires were administered to patients by convenience sampling. Two sets of questionnaires were used, one for inpatient and another one set for outpatient. Selection of hospitals was made according to states in Peninsular Malaysia. 23 hospitals covering all state level hospitals, the National Referral Centre and selected district hospitals were chosen as respondent hospitals. Two dimensions of service quality emerged, namely clinical and physical dimension of service. Both outpatient and inpatient were found to be more satisfied with clinical dimension of service than physical dimension. For outpatient satisfaction, there was positive correlation between waiting time and patient satisfaction. Patient satisfaction was also found to be higher in the smaller district hospitals than in the larger state hospitals. For clinical dimension of service, patients were satisfied with the services of doctors and nurses, while for physical dimension of service, patients were satisfied with the cleanliness of the facilities. The ability of the research to be conducted by random sampling was inhibited by the reluctance of patients to cooperate, which led to the use of convenience sampling. Studies have also shown that patients are reluctant to express their feelings on services provided by their caregivers. The study provides primary data for a nationwide study on patient satisfaction in Malaysian public hospitals, for both inpatient and outpatient.

The purpose of this research is to investigate the factors affecting Thai commercial bank users' behavioral intention towards QR code payment system via mobile banking applications. The researchers conducted the study based on quantitative research approach. Non-probability sampling method such as the quota and convenience sampling was applied as sampling technique. A self-administered questionnaire was distributed. The data was collected from 1,800 respondents living in Bangkok, who have had an experience with QR code payment system with the top-three mobile banking applications in Thailand. This study concentrates on confirmatory factor analysis and structural equation modeling as a statistical tool to examine the data, model accuracy, and influence of critical variables. In addition, the researchers applied the first-order and second-order techniques to examine the relationship between constructs. Adoption readiness and perceived risk were second-order constructs. The results reveled that compatibility has an impact on attitude towards QR code payment. Moreover, adoption readiness, compatibility, attitude, and personal innovativeness are statistically significant that impact behavioral intention towards QR code payment. The strongest antecedents of behavioral intention were compatibility, attitude, adoption readiness, and personal innovativeness, respectively. Surprisingly, perceived risk and perceived trust do not statistically have a significant impact on behavioral intention towards QR code payment.

Objectives: The purpose of this study is to analyze the factors affecting the self-perceived halitosis of adults and to utilize them as basic data for the development of prevention and management program to reduce of self-perceived halitosis. Methods: A questionnaire survey of 301 adults in their 20s and 50s living in Gwangju and Jeonnam selected by convenience sampling from July 1, 2017 to August 31, 2017 was conducted to investigate oral health status and behavior, fatigue and perceived stress. Statistical analysis was performed using frequency analysis, independent t-test, one way ANOVA, Pearson's correlation analysis, and multiple regression analysis. Results: The degree of self-perceived halitosis was higher in married (2.51) and unemployed (2.71), with tongue brushing (2.68), intention to participate in halitosis education (2.57), taking medication (2.73), coated tongue (2.82) and there was both otolaryngology and gastrointestinal disease (2.72) and periodontal disease (2.89) (p<0.05). Fatigue (${\beta}=0.237$), periodontal disease (${\beta}=0.196$), and coated tongue (${\beta}=0.237$) affect the self-perceived halitosis (p<0.001). Conclusions: The self-perceived halitosis in adults was correlated with fatigue and perceived stress. Also fatigue, periodontal disease, coated tongue factors were analyzed as factors influencing self-perceived halitosis. Additional studies such as prevention and management of periodontal disease and coated tongue, which is a factor of self-perceived halitosis in adults, and development of programs to reduce self-perceived halitosis for fatigue management, which is an external factor, are necessary.
