The objective of this study is to explore the effects of e-teaming users' self-efficacy and perceived service quality for e-teaming staffs such as instructors or teaching assistants on two main perceptions for e-learning systems in a view of information technology - perceived ease of use and perceived usefulness which have been considered as important antecedents for acceptance of information technology so called in Technology Acceptance Model. For this purpose, we suggest a research model and test it empirically by sampling in students of virtual universities. In result, all hypotheses except the relationship between academic self-efficacy and perceived usefulness are accepted. This result implies that self-efficacy for computers and service quality for staffs such as instructors or teaching assistants should be considered as important ones for success of e-learning systems in addition to those related with information technology.

The role of consumer self-confidence is important in consumer's purchase decision. Nevertheless, the use of self-esteem measures might cause misinformation in the specific situation of the marketing-related point of view. In this study, consumer self-confidence was measured by marketing oriented tools to clarify the dimensions of consumer self-confidence while the influence of consumer self-confidence on clothing satisfaction was also investigated. A total of 325 questionnaires were collected by surveying university students in Seoul and the surrounding metropolitan area using convenient sampling. The data were analysed by factor analysis, ANOVA, t-test, and regression by using SPSSWIN program. The findings of the study were as fellows. First, the consumer self-confidence was composed of 6 sub-scales: information acquisition, personal outcomes decision making, social outcomes decision making, consideration-set formation, persuasion knowledge, and marketplace interfaces. Second, female subjects rated higher on consumer self-confidence than male subjects did in social outcomes decision making and consideration-set formation. Third, higher income was correlated with higher social outcomes decision making and consideration-set formation.

Objectives : The purpose of this study was to examine the impact of the self-efficacy of dental hygienists on their stress-coping method. Methods : The subjects in this study were the dental hygienists in dental institutions that were selected by convenience sampling from Jeonju, Iksan, Gimjei and Gunsan in North Jeolla Province. A survey was conducted by using structured questionnaires. Results : A regression analysis was carried out to see whether self-efficacy would affect stress-coping method, and it's found that those whose overall self-efficacy was better made more use of an overall stress-coping method(p>0.001). General and social self-efficacy exerted a significant influence on a problem-oriented stress-coping method(p>0.001, p>0.01), and general and social self-efficacy had an impact on a stress-coping method of social support pursuit(p>0.01, p>0.01). In addition, general and social self-efficacy exercised an influence on a stress-coping method of wishful thinking(p>0.01, p>0.05). Conclusions : The self-efficacy of the dental hygienists affected their own stress-coping method, and the finding of the study suggests that a lot of efforts should be made from diverse angles to boost the self-efficacy of dental hygienists.

This study was designed to investigate the relationship between the stages of exercise behavior change and physical self-concept and self-efficacy of security employees in hotel casinos. The sampling was drawn from employees at 8 casinos which had more than 30 employees. Participants were selected by convenience sampling method and they completed questionnaires about Physical Self-Concept and Self- Efficacy by self-administration method under supervision of trained researchers SPSS 16.0 (Statistical Package for the Social Science) was used for data analysis in the present study. Reliability and validity were examined for the present study. The principle component factor analysis and varimax rotation were used for the present study. Eigen value 1.0 was the criterion for selecting factors. Chi-square (X) 2 test was utilized for measuring the difference in gender and types of job duties at the stages of exercise behavior change. One-way ANOVA was employed to examine the relationship between the stages of exercise behavior change as an independent variable and physical self-concept and self-efficacy as dependent variables. The Scheffe method was used to determine mean differences of groups as a follow-up test. Multiple regression analysis was utilized to test the difference of physical self-concept as dependent variable and self-efficacy as independent variable. To verify hypothesis for the study, a statistical significance level of $\alpha$=.05 was used. The results were as follow: first, there were differences found for gender and types of job responsibilities in the stages of exercise behavior change. Secondly, as security employees progressed through the stages of exercise behavior change, their physical self-concept and self-efficacy improved. Finally, physical activity and body fat had significant main effects on self-efficacy.

The study aims to explore the empirical effect of social intelligence, integrity, self-efficacy, and affective commitment on job satisfaction, and also to prove the theoretical model regarding affective commitment as a mediator between social intelligence, integrity, self-efficacy, and job satisfaction. This research uses a quantitative approach to the survey method through a Likert scale model questionnaire. The questionnaire for all research variables is reliable with an alpha coefficient > 0.7. The research participants are comprised of 386 teachers in Indonesia selected by accidental sampling. Data analysis uses path analysis supported by descriptive statistics and correlational matrices. The research results indicate that social intelligence, integrity, self-efficacy, and affective commitment have a significant effect on job satisfaction. Besides, affective commitment also indirectly mediates the effect of social intelligence, integrity, and self-efficacy on job satisfaction. Thus, a new model regarding the effect of social intelligence, integrity, and self-efficacy on job satisfaction mediating by affective commitment was confirmed. The research suggested that the teachers' job satisfaction can improve through social intelligence, integrity, self-efficacy, and affective commitment. Therefore, researchers and practitioners can adopt a new empirical model to enhance job satisfaction through social intelligence, integrity, self-efficacy, and affective commitment in the future.

Due to its simplicity and high reliability, the box-counting(BC) method is one of the most frequently used techniques to estimate the fractal dimensions of a binary image with a self-similarity property. The fractal calculation requires data sampling that determines the size of boxes to be sampled from the given image and directly affects the accuracy of the fractal dimension estimation. There are three non-overlapping regular grid methods: geometric-step method, arithmetic-step method and divisor-step method. These methods have some drawbacks when the image size M becomes large. This paper presents a BC algorithm for enhancing the accuracy of the fractal dimension estimation based on a new sampling method. Instead of using the geometric-step method, the new sampling method, called the coverage ratio-step method, selects the number of steps according to the coverage ratio. A set of experiments using well-known fractal images showed that the proposed method outperforms the existing BC method and the triangular BC method.
