This study examined the relationship among self-control, physical activity, Internet addiction, cyber ethnics, and cyber delinquency. The data from a total of 388 adolescent girls was analyzed by structural equation modeling using the AMOS 20.0 statistics program. First, the level of physical activity affects Internet addiction mediated by self-control. Second, self-control affects Internet addiction and cyber ethnics directly and has an influence on the cyber delinquency mediated by Internet addiction. Third, Internet addiction has direct effects both cyber delinquency and cyber ethnics.

This study aimed to develop the short-form of age-friendly scale which was suitable for the Korean cities and to examine the validity. To develop the scale, WHO and Seoul welfare foundation's age-friendly city guide were compared and analyzed. The data for this study were collected on people aged over 55 years old living in Seoul. The results in exploratory factor analysis showed that seven-factor structure model was appropriate for the scale. Seven factors were outdoor amenity, transportation, leisure activity, social participation, social communication, health and welfare service, social exclusion. The results supported the construct and concurrent validity of the age-friendly scale. Also its good internal consistency was confirmed. The implication and limitation of the study and suggestions for the future studies were discussed.

Objective: The purpose of this study was to evaluate the effects of malocclusion on the self-esteem of female university students. Methods: The subjects were composed of 67 female university students who showed Class 1 molar relation, no missing or supernumerary teeth and has had no orthodontic treatment experience. Each subject was evaluated with Rosenberg's Self-esteem Scale to measure the level of self-esteem and also evaluated the degree of anterior crowding and lip protrusion through model analysis and cephalometric soft tissue profile analysis. Results: The results showed that a protrusive profile and crowding of upper anterior teeth had significant reducing effects on the level of self-esteem. The protrusion and crowding groups showed no significant differences in self-esteem between groups. Conclusions: Malocclusion had significant negative effects on the self-esteem of female university students. Further research to investigate the negative psychological influence of malocclusion and the education of lay people about this influence is necessary.

This article studies the understanding of acid and base concepts of the 3rd-grade students in middle school. An effective teaching strategy for improving their acid and base concepts was designed by considering students' prior knowledge using Lawson's learning cycle method. The control group was adapted by the traditional teaching strategy which isn't considering students' prior knowledge. After the class, understanding of acid and base concepts of treatment group was significantly higher than that of control group. But the level of students' understanding of strong acid, weak acid strong base and the strength of acid in aqueous solution was low even after the class of two groups. This indicates indirectly that the microscopic views of acid and base concepts in aqueous solution are not easy to learn for these students. For the four categories of acid and base concepts, students' responses were reviewed carefully and classified into scientific conceptions and misconceptions. These results will be useful for developing an effective teaching strategy of acid and base concepts.

The purpose of this study was to validate the Korean version of Inventory of Parent Attachment(K-IPA), The first version of K-IPA was developed through the process of translation and tack translation of items of parent attachment from Inventory of Parent and Peer Attachment (Armsden & Greenberg, 1986), content validation test with 30 elementary school children, and content validation test with an expert group. The validation test with 964 students (emementary, middle, high school) confirmed all 25 items(each items were asked for mother and father) were appropriate and reliable, K-IPA consists of three different sub-scales, 10 items for trust scale, 9 items for communication scale, and 6 items isolation across all age groups.

This study aimed to develop a scale to measure physical health behaviors among social work clients using general services. The scale items were constructed based on literature review and FGI of social workers. Exploratory factor analysis and confirmative factor analysis affirmed the factor structure of Physical Health Behavior Scale with two sub-scales: Health Promotion Behavior Scale and Health Hindrance Behavior Scale. Promotion Scale had 7 factors and Hindrance Scale had 5 factors. Both sub-scales showed acceptable ranged goodness-of-fit for the model, and internal consistency test proved that the scale was reliable. The analyses of discriminant validity, convergent validity, and concurrent validity resulted significant validation. Based on those results, the developed Physical Health Behavior Scale were proved well-constructed, reliable and valid. The Scale will be utilized for both clients in general to check their own health related behaviors and social workers to adopt as a tool for assessment in order to perform an evidence based practice.

The purpose of this study was to investigate the relationship among leisure constraints, athletic life satisfaction and self-control of student athletes at physical education high school. By using convenience sampling method of non-provability sampling, a total 217 students athletes from D and G city were selected. Of 217 copies of the questionnaire gathered, 35 were discarded owing to having excessive missing values. Thus by analysing a total of 182 surveys with structural equation modeling through SPSS 20.0 statistics program, this study found the followings. First, leisure constraints have a negative influence on athletic life satisfaction. Second, leisure constraints have a negative influence on self-control. Third, athletic life satisfaction has a positive influence on self-control.

The purpose of this study is to explore physical factor of digital text structure for designing e-Book interface and to develop prototype of e-Book interface by applied these factors. To address this goal, explore factor analysis and confirmatory factor analysis were employed, 237 university students were the participated in this study. According to a result, 29 items for physical feature of digital text structure were developed, 9 factors of digital text structure were also extracted; volume, depth, density, space, layout, format, signal, size, and length. Besides, to identify structure of pre-defined 9 factors, confirmatory factor analysis was conducted. As a result of CFA, the factor structure was supported by all of model fit indices.

The purpose of this study was to examine the effect of social support from friend, senior junior, and coach on student-athletes' stress and deviant behavior. By using convenience sampling method of non-probability sampling, a total of 350 student-athletes from D and G city were selected. Of 217 copies of the questionnaire gathered, 35 were discarded owing to having excessive missing values. Thus, by analysing a total of 182 surveys with structural equation modeling through AMOS 20.0 statistics program, this study found the followings. First, social support has a negative influence on stress. Second, stress has a positive influence on deviant behavior. Third, social support has a negative influence on deviant behavior mediated by stress.

This study explored the factors that decided to choose buffet restaurant. We have identified and recently, developed event factors that are of increasing importance. The event factor demonstrated the relationship between customer satisfaction and behavioral intention. As a result, the event factors had a positive effect on customer satisfaction and behavioral intention. In this study, event factors were derived and measurement questions were developed using semiotic analysis. The developed measurement questions were tested and surveyed to demonstrate the scale.
