  • The purpose of this study was to assess the effects of self-image congruence on attitudes toward purchase intentions of children's clothing via the Behavioral Intention Model. The empirical study was conducted via on-line survey and data were collected from mothers with children aged 6 to 10 years. A total of 593 respondents answered the questionnaire and 574 usable data were statistically analyzed. SPSS 18.0 was used to conduct descriptive statistical analysis, factor analysis, reliability analysis, cluster analysis, Chi-square test, ANOVA, and multiple regressions. A K-means cluster analysis was conducted based on three dimensions brand images of children's wear. Respondents were divided into four groups: elegant image group, multiple image group, ordinary image group, and childlike image group. Characteristics of consumers and clothing evaluative criteria that mothers considered important differed significantly across groups. Moreover, based on these groups, each dimension of self-congruence had different effects on brand attitude. Brand attitude and subjective norms had different effects on purchase intentions. In conclusion, levels of self-congruence and factors influencing purchase intention varied according to brand images of children's wear.

  • Purpose: This research aims to explain the influence of social media influencer (SMI), electronic word of mouth (EWOM), and perceived quality (PQ) on purchase intention (PI) of beauty products on YouTube. Youtube as the number 1 social media in Indonesia, has an important role as a promotional strategy media for beauty products. Research design, data and methodology: This study used the online survey to 210 female respondents aged 17-30 years who became a subscriber of an Indonesian beauty influencer. Simple regression and multiple regressions were performed to analyze the independent variables towards the dependent variable. Results: The results show that social media influencer, electronic word of mouth, and perceived quality simultaneously have a significant influence on purchase intention. Nevertheless, only two variables individually have a significant influence on purchase intention, which is social media influencer and perceived quality. Conclusions: Perceived quality and social media influencer could be the best strategies to increase consumers when promoting through the influencer's Youtube channel by utilizing a subscriber. While e-WOM can be influential on other social media platforms rather than on the Youtube platform. Therefore, suggested that digital marketer must use multiple social media platforms to increase consumers' purchase intention.

  • Purpose - This study aims to examine the determinants of income management of the public servant. Three independent variables are examined such as attitude towards money, financial capability and debt management while the dependent variable is financial wellbeing of public servants. Research design, data, and methodology - Quantitative research is applied in this study, and data are collected by using cross sectional approach. Survey questionnaires are obtained from 270 respondents, which represents 79% response rate. The multiple regressions are used to examine the influence of attitude towards money, financial capability and debt management towards financial wellbeing. Results - The result of the multiple regression indicated positive influences of attitude towards money and financial capability on financial wellbeing. However, debt management found no significant influence on financial wellbeing. Conclusions - Research findings show that people have different attitudes towards money and different trends of expenditure. It is also crucial to be highlighted that employees' attitude and financial capability have a greater influence on overall satisfaction with employees' financial wellbeing. Some would want to show off their luxury items they bought to close friends or relatives and some are very prudent in making expenditures even for necessity items.

  • In this study, artificial neural network (ANN) and multiple regression (MR) models were developed to predict the critical factor of safety ($F_s$) of the homogeneous finite slopes subjected to earthquake forces. To achieve this, the values of $F_s$ in 5184 nos. of homogeneous finite slopes having different slope, soil and earthquake parameters were calculated by using the Simplified Bishop method and the minimum (critical) $F_s$ for each of the case was determined and used in the development of the ANN and MR models. The results obtained from both the models were compared with those obtained from the calculations. It is found that the ANN model exhibits more reliable predictions than the MR model. Moreover, several performance indices such as the determination coefficient, variance account for, mean absolute error, root mean square error, and the scaled percent error were computed. Also, the receiver operating curves were drawn, and the areas under the curves (AUC) were calculated to assess the prediction capacity of the ANN and MR models developed. The performance level attained in the ANN model shows that the ANN model developed can be used for predicting the critical $F_s$ of the homogeneous finite slopes subjected to earthquake forces.

  • Purpose: The purpose of this study was to identify motivational factors that may influence health behaviors of patients with coronary artery disease. Methods: Structured questionnaires were used with a convenience sample of 164 subjects who were discharged from the hospital. The subjects were recruited for an interview at outpatient clinic in hospitals. The tools for the study were the motivational factors and health behaviors measure for the Elderly with cardiovascular disease. The data were analyzed using frequency, t-test, ANOVA, sheffe, Pearson correlation coefficient and stepwise multiple regressions. Results: There were significant correlations between motivational factors and health behaviors, ranging from r=.192 to .692. Stepwise multiple regression analyses indicated that 51% of variance in health behaviors was explained by self-efficacy and perceived benefits among four motivational factors(F=34.988, p<.01). Self-efficacy contributed the greatest amount of variance in health behaviors(${\beta}=.467$), followed by perceived benefits(${\beta}=.235$). Conclusions: The results of the study indicate that motivation, especially self-efficacy, was very important in predicting health behaviors of patients with coronary artery disease. Thus it would be necessary to include motivational factors in designing rehabilitation program for people with coronary artery disease.

  • The present study established prediction models based on multiple nonlinear regressions (MNLRs) and backpropagation neural networks (BPNs) for the expansion of cement mortar caused by oxidization slag that was used as a replacement of the aggregate. The data used for the models were obtained from actual laboratory tests on specimens that were produced with water/cement ratios of 0.485 or 1.5, within which 0%, 10%, 20%, 30%, 40%, or 50% of the cement had been replaced by oxidization slag from electric-arc furnaces; the samples underwent high-temperature curing at either $80^{\circ}C$ or $100^{\circ}C$ for 1-4 days. The varied mixing ratios, curing conditions, and water/cement ratios were all used as input parameters for the expansion prediction models, which were subsequently evaluated based on their performance levels. Models of both the MNLR and BPN groups exhibited $R^2$ values greater than 0.8, indicating the effectiveness of both models. However, the BPN models were found to be the most accurate models.

  • Purpose: The purpose of this study was to investigate the factors influencing the health-promoting behaviors of the people living with HIV. Methods: Descriptive cross-sectional study design was used. The study participants included 99 people living with HIV recruited via the Korea HIV/AIDS Network of Solidarity from May 15 to August 15, 2012. Self-report questionnaires were used fo data collection measuring perceived stress, depression, self-efficacy, health-promoting behaviors (HPLP-II), and the perceived health status. The analysis was done using SPSS/Win 18.0 program. Descriptive statistics, pearson correlation, t-test, ANOVA and stepwise multiple regressions were used for data analysis. Results: Perceived stress (r=-.21, p=.040), depression (r=-.37, p<.001), self-efficacy (r=.42, p<.001), perceived health status (r=.29, p=.003), and health-promoting behaviors were significantly correlated with each other. The self-efficacy, religion and perceived health status were significant factors, which explained about 26% of the variance of the health-promoting behaviors. Multiple regression analysis showed that a powerful predictor of health-promoting behaviors among people living with HIV was self-efficacy. Conclusion: This study suggested that a focus of nursing intervention program on self-efficacy is necessary in order to increase health-promoting behaviors among people living with HIV.
