This study examined the structural relationship among personal belief in a just world, presence of meaning in life, self-control, and aggression in college students. For this research, self-reported data from 427 college students were analyzed by gender, using structural equation modeling. Results indicated that personal belief in a just world predicted aggression regardless of gender. The mediating effect of self-control was non-significant among both women and men groups. The mediating effect of presence of meaning in life and self-control was significant among only women. It means that personal belief in a just world predicted presence of meaning in life and self-control, which consequently contributed to aggression among women. It is noteworthy that this study examined the concrete mechanism to reduce aggression by gender. Based on these findings, intervention strategies were discussed.

The current study was conducted to examine the dual mediating effect of dysfunctional belief and ambivalence over emotional expressiveness in the relationship between the parents' psychological control scale perceived by university students and interpersonal problems. For that purpose, 305 4-year university students in G Metropolitan City and J Province were surveyed to rate the parents' psychological control scale, dysfunctional belief, ambivalence over emotional expressiveness, and interpersonal problems. The data were analyzed using SPSS 22.0 and SPSS Macro. As a result, it was found that dysfunctional belief and ambivalence over emotional expressiveness had a mediating effect in the relationship between the parents' psychological control scale and interpersonal problems. Also, dysfunctional belief and ambivalence over emotional expressiveness had a dual mediating effect on the relationship between psychological control scale and interpersonal problems. As a result of testing the significance of the mediating effect through Bootstrapping, dysfunctional belief and ambivalence over emotional expressiveness had a significant dual mediating effect. The purpose of the current study was to establish a useful theoretical foundation for counseling strategies to efficiently help through counseling the university students who are having difficulties with interpersonal relations due to parental control.

BACKGROUND/OBJECTIVES: The objective of this study was to examine factors affecting cooking behavior at home. We examined components of the theory of planned behavior, perception of cooking skills, and socio-demographic variables affecting cooking behavior at home. SUBJECTS/METHODS: The study sample included 425 women raising elementary school children living in South Korea. They responded to an online structured questionnaire. The variables affecting cooking behavior at home were assessed using hierarchical regression analysis. RESULTS: The frequency of cooking behavior at home was 14.1 meals per week. Most respondents showed an intention regarding cooking behavior. The average score for attitude toward cooking behavior at home was 15.1 points (scale of 1 to 25). Attitude and cooking behavior showed a significant positive correlation (P < 0.01, r = 0.22). The subjective norm was 14.6 points (scale of 1 to 25). The subjective norm showed a significant correlation with cooking behavior (P < 0.01, r = 0.18). The control belief was 2.8 points (scale of 1 to 5). The control belief and cooking behavior showed a significant correlation in all questions (P < 0.01, r = 0.25). The subjects were significant confident about their cooking skills, except for Kimchi. Perception of cooking skills showed a significant correlation with all questions concerning cooking behavior (P < 0.01, r = 0.30). Significant variables for predicting intention regarding cooking behavior were perception of cooking skills, employment status, income, and attitude. Significant variables for predicting cooking behavior were employment status, income, control belief, number of children, and behavioral intention. CONCLUSIONS: In order to provide nutrition education to increase cooking behavior at home, it is necessary to have a positive attitude toward cooking behavior, increase control belief, and improve confidence related to cooking skills. Moreover, differentiated education based on the employment status of women is needed.

The purpose of this study was to assess the causal relationships among belief, subjective norm, moral feeling, attitude, and the intention to consume organic beef. A total of 326 questionnaires were completed by adult in Jeonnam area. Structural equation modeling was used to measure the causal relationships among the constructs. The structural analysis results indicated an excellent model-data fit. The covariance effects of belief and subjective norm, and belief and moral feeling were statistically significant. The effects of belief and moral feeling on attitude and intention to consume were also statistically significant. As expected, attitude had significant effects on intention to consume. Moreover, attitude played a mediating roles in the relationship between belief and intention to consume. Finally, based on structural analysis, a model was proposed for the interrelations among belief, subjective norm and moral feeling towards organic food, attitude and intention to consume. It should be noted that the original organic food consumption model was modified, and should preferably be validated by future research. Other constructs, such as perceived behavior control and consumption, may be incorporated to form models that consist of new antecedent and consequence pairs.

The purpose of this study was to identify the effectiveness of concepts on global warming, practical will and belief on global warming mitigation by experiments based on global warming program. For this study, 60 $6^{th}$ grade students were selected in two elementary schools. They were divided into an experimental group and a control group. The students of the experimental group took part in global warming program focusing experiments for 10 lessons during 2 weeks. The students of the control group were taught according to the regular curriculum of $6^{th}$ grade about global warming. To identify the effects of this program, both groups' students were tested on concepts on global warming, practical will and belief on global warming mitigation before and after the program implementation. Also the students of the experimental group wrote an essay and gave an interview about the program after implementation. The results were that the experimental group gained higher scores than the control group in the concepts on global warming. The programs improved students' practical will and belief on global warming mitigation. Also this program showed that the students systematically understood on global warming than existing classes in the regular curriculum.

High and intermittent loading cycles induce fatigue damage to transmission components, resulting in premature gearbox failure. To identify gearbox defects, numerous vibration-based diagnostics techniques, using several artificial intelligence (AI) algorithms, have recently been presented. In this paper, an optimized deep belief network (DBN) model for gearbox problem diagnosis was designed based on time-frequency visual pattern identification. To optimize the hyperparameters of the model, a particle swarm optimization (PSO) approach was integrated into the DBN. The proposed model was tested on two gearbox datasets: a wind turbine gearbox and an experimental gearbox. The optimized DBN model demonstrated strong and robust performance in classification accuracy. In addition, the accuracy of the generated datasets was compared using traditional ML and DL algorithms. Furthermore, the proposed model was evaluated on different partitions of the dataset. The results showed that, even with a small amount of sample data, the optimized DBN model achieved high accuracy in diagnosis.

Objectives : The purpose of this study was to investigate the association factors of infection control practice based on health belief model in the dental hygienists in dental clinics. Methods : A self-reported questionnaire was filled out by 278 dental hygienists in 160 dental clinics in Gwangju by a proportional stratified sampling method from September 13 to October 7, 2013. Data were analyzed by t-test, ANOVA, correlation analysis, and multiple regression analysis using SPSS version 12.0. Results : In multiple regression analysis, practice scores were significantly higher in aged dental hygienists and those who took infectious disease history from the patients before treatment. With regard to health belief model, perceived barrier was negatively associated with the practice(${\beta}$=-.16, p<.001), importance of infection control in hand hygiene(${\beta}$=.14, p=.026), and use of personal protective equipment(${\beta}$=.17, p=.043). The intention of action was positively associated with the practice(${\beta}$=.13, p=.002). Conclusions : This study will provide the basic evidence for the quality improvement of infection control and prevention. So the dental hygienists will be able to put into practice in infection control management.

Background: Breast cancer is one of the most common cancers among women in the world. Early detection is necessary to improve outcomes and decrease related costs. The aim of this study was to assess the predictive power of health locus of control as a modifying factor in the Health Belief Model (HBM) for prediction of breast self-examination. Materials and Methods: In this cross- sectional study, 400 women selected through the convenience sampling from health centers. Data were collected using part of the Champion's HBM scale (CHBMS), the Health Locus of Control Scale and a self administered questionnaire. For data analysis by SPSS the independent T test, Chi square test, logistic and linear regression modes were appliedl. Results: The results showed that 10.9% of the participants reported performing BSE regularly. Health locus of control did not act as a predictor of BSE as a modifying factor. In this study, perceived self-efficacy was the strongest predictor of BSE performance (Exp (B) =1.863) with direct effect, while awareness had direct and indirect influence. Conclusions: For increasing BSE, improvement of self-efficacy especially in young women and increasing knowledge about cancer is necessary.

In order to determine the effect of individual patient teaching through home visiting on compliance with sick role behavior and the blood sugar level in diabetic patients, to determine if the effectiveness of the education was still present four year later and to inquire as to the effective time for a repeat education program this study was done through two quasi-experimental researches. The subjects consisted of 52 diabetic patients. The results of the study may be summarized as follows ; 1. Hypothesis I, in which the compliance with sick role behavior, the knowledge on diabetes and the health belief of the experimental group who received a diabetic education program will be higher than those of the control group who didn't receive the diabetic education, was supported by both studies in 1984 and 1988, confirming the effect on diabetic patients of the individualized education through home visiting ; In the 1984 study : Compliance(t＝-11.7, p＜.001) Knowledge(t＝-5.41, p＜.001) Health belief(t＝-4.74, p＜.001) In the 1988 study : Compliance(t＝-4.85, p＜.001) Knowledge(t＝-2.85, p＜.01) Health Belief(t＝-2.99, p＜.005) 2. The Hypothesis II, the blood sugar level of the experimental group will be lower than that of the control, was rejected in both studies, 1984 and 1988. 3. The Hypothesis III, the compliance, knowledge and health belief of the expermental group who received the education program in 1984 will not last till 1988, was supported in part, in compliance and health belief, but not in knowledge. In conclusion those who received the education program twice with an interval of 2 weeks, 4 years ago still had knowledge of diabetes but compliance and health belief had disappeared.
