Nowadays an information exchange on Bn such as B2B electronic commerce is spreading. Therefore the systematic and stable management mechanism for storing the exchanged information is needed. For this goal there are many research activities for connection between XML application and relational database. But because XML data have hierarchical structures and relational database can store only flat-structured data, we need to store XML data in object-relational database that support hierarchical structure. Accordingly the modeling methodology for storing XML data in object-relational database is needed. In order to build good quality application systems, modeling is an important first step. In 1997, the OMG adopted the UML as its standard modeling language. Since industry has warmly embraced UML its popularity should become more important in the future. So a design methodology based on UML is need to develop efficiently XML applications. In this paper, we propose a unified design methodology for In applications based on object-relational database using In. To this goal, first we introduce a XML modeling methodology to design W3C XML schema using UML and second we propose data modeling methodology for object-relational database schema to store efficiently XML data in object-relational databases.

This study examined the effects of young children's effortful control and emotional regulation, teacher-child conflictual relationships on young children's overt and relational aggression. The subjects of this study were 372, 3-5 years old children and their teachers. Young children's aggression, effortful control, emotional regulation, and teacher-child relationships were assessed by a teacher's report. The collected data were analyzed by t -test, Pearson correlations, and pathway analysis. The results were as follows: first, the boys' overt aggression was found to be greater than that of the girls,' while, there was no difference in relational aggression between boys and girls. Second, the boys' and girls' effortful control was found to affect the young children's overt and relational aggression indirectly through emotional regulation, and teacher-child conflictual relationships. For the girls, effortful control was found to affect overt aggression directly. Third, teacher-child conflictual relationships and emotional regulation were found to affect boys' and girls' overt and relational aggression directly and to mediate between boys' and girls' effortful control and overt and relational aggression. Further, for girls, emotional regulation was found to mediate between teacher-child conflictual relationships and overt and relational aggression. Additionally, effortful control was found to be the most important variable predicting boys' and girls' overt aggression, while a teacher-child conflictual relationship was the most important variable for boys' and girls' relational aggression.

This study was performed under the need for systematic analysis about the effect of religious activity of a protestant married women in Korea on the relational satisfaction between her and her family members. It was separately analyzed that church-centered religious activity and home-centered religious activity. The purpose of this study are to propose religious activity that could allow for a satisfactory relationship between all family members of a protestant married women, and to contribute to make a harmonious family through recommended activities for a protestant family and church to accept and carry out. The analyses of the results are in case of the pure explanation power that religious activity has on a protestant married women and her family member’s relational satisfaction, the couple relational satisfaction degree from wife is 4.6%, the one from husband is 4.4%, the mother-child relational satisfaction degree from mother is 2.5%, and the one from child is 1.5%. Therefore effect of religious activity on family member’s satisfaction is more couple relational satisfaction than mother-child relational satisfaction, and the significant variable on all the relationships between the protestant married women and her family members are home-centered religious activity.

A temporal database systems provides timing information and maintains history of data compared to the conventional database system. In this paper, we present a temporal relational database which use an interval-stamping method for instant-based events and for interval-based states. A set of temporal algebraic operators are developed on an instance of time and interval of time so that we can manipulate events and states at a same time. The set of operation is the basis for creating a relational algebra that is closed for temporal relations. And temporal SQL is also suggested as a temporal query relational language for our algebraic operations on temporal relations.

Purpose - Augmented reality (AR) content used in mobile media today can accommodate a wide variety of contextual information. This indicates that making people experience a sense of presence and flow is a very significant factor in augmented reality content. Flow represents a rich immersion potential as representing the progress of emotion and the means to facilitate the operation of the smart phone. Therefore, users will have friendly relational continuance behavior with products and brands that supply this experience. Based on that, the purpose of this study is to investigate the relationships among smart phone AR application traits, presence, flow experience, and relational continuance behavior. First, AR application traits are defined as three categories sensory immersion, navigation, and manipulation, based on preceding studies. This study then examines the influence of AR application traits on the presence and flow experience and looks into the relation among presence, flow experience, and relational continuance behavior. This analysis suggests more detailed and concentrated strategic implications. Research design, data, and methodology - A research model is designed to examine the relation among AR application traits, presence, flow experience, and relational continued behavior. For data collection, questionnaire surveys were composed of multi-items for each component and the direct interview method was used for the interviews. To collect the data, after running the smart phone AR applications, the consumer behaviors of the respondents were generally determined. The questionnaire surveys were conducted for one month, October 2014. A total of 300 questionnaires were distributed with 278 questionnaires used for analysis, excluding the unanswered and insincere questionnaires. The data were analyzed using SPSS ver. 20.0 and LISREL ver. 8.51. Results - The following results are found: First, AR application traits have a significantly positive effect on presence with sensory immersion, navigation, and manipulation all having a significantly positive effect. Second, sensory immersion and manipulation among the AR application traits have a significantly positive effect on flow. However, navigation did not have a significantly positive effect on flow. Third, presence has a significantly positive effect on flow and has a significantly positive effect on relational continuance behavior. Moreover, flow also has a significantly positive effect on relational continuance behavior. This behavior tends to be formed since brands want to encourage relational continuance behavior and positive emotions with the brands being used. Relational continuance behavior accompanies repeat purchasing, positive word-of-mouth and recommendation activities, and forms of trust with the brand. Conclusions - The research results showed that smart phone AR traits had significantly positive effect on presence, flow, and relational continuance behavior. Based on this, smart phone AR application providers should establish an aggressive marketing strategy to accommodate more realistic problems in order to positively influence user behavior. Additionally, the marketers should make efforts to provide fun or convenience in the AR application operation process of the user.

The purpose of this study is to develop and verify the Relational Self Scale(RSS). Based on the theoretical assumptions which relational self is multi-dimensional and constructed in social contexts, 10 categories with 102 items were yielded. In the process of content analysis, item analysis, exploratory factor analysis and correlation analysis by administering 102 items to korean adults, 31 items with 7 factors are extracted. The 7 factors are consisted of 'avoidance of relation', 'consciousness of others', 'agency', 'instrumental relation', 'empathy-care', 'perceived support from relation' and 'over-dependency to relation'. Next, Confirmatory factor analysis was conducted with 649 korean adults aged from 20's to 60's. The results of confirmatory factor analysis showed the RSS as a valid scale. The 7 factors of the RSS fitted well with men and women. The internal consistency of the RSS was proved to be acceptable. The latent mean analysis indicated that the relational self was not significantly different between men and women at 7 factors. Correlation analysis showed that the construct of relational self was significantly related to relational self-construal, self-esteem and attachment to parent and intimacy person. This study has implication in that relational self is defined and assessed as multi-dimensional construct, and that by administering RSS it is possible to evaluate distinctive korean people's relational self.

In order to determine whether there is a significant correlation between relational understanding and creative math. problem finding ability, this study performed relational understanding and problem finding ability tests on a sample of 186 8th grade middle school students. According to the study results, we found a very significant positive correlation between relational understanding and the creativity of the mathematising ability and the combining ability of mathematical concepts in the problem finding ability. Although there was no statistically significant correlation between relational understanding and the extension ability of mathematical facts, the results from analyzing the students response rate and actual scores in each test showed that students with high relational understanding scores also had high response rate and high scores in analogical reasoning and inductive reasoning. Through this study, therefore, relational understanding is found to have a positive impact on the creative mathematics problem finding ability.

This study aims to identify the factorial constructs of the relational benefits perceived by consumers of outdoor wear brands and their impacts on the consumers' trust in and satisfaction with outdoor wear brands. An online survey was conducted with females and males between the ages of 20 and 50 who have experienced buying outdoor wear brands. A total of 420 responses were analyzed by factor analysis, a reliability test, and multiple regression analysis. The results of this study were as follows: first, the results of factor analysis and the reliability test on the relational benefits perceived by outdoor wear brand purchasers clearly showed conceptual constructs that included informational benefits, social benefits, and psychological benefits. The sub-dimension of perceived relational benefits had significant effects on brand trust and satisfaction. Specifically, respondents revealed that they had higher brand trust if they felt psychologically comfortable, were offered useful information by outdoor wear brands, and had a favorable relationship with salespeople when they bought outdoor wear merchandise. Secondly, influences of perceived relational benefits on brand trust and satisfaction were not shown to differ depending on the congruity between outdoor wear brands and the purchaser's self-image. On the other hand, factors of perceived relational benefits revealed to differently have effects on brand trust and satisfaction depending on respondents' gender and age. Practical implications to understand outdoor wear target customers' relational benefits, self-image congruity and demographic characteristics and to enhance trust and satisfaction with outdoor wear brands are proposed.

The purposes of this study were (1) to explore the gender differences in children's overt aggression and relational aggression and (2) to investigate the effects of preschool children's gender, temperament, emotional regulation, and maternal parenting stress on overt aggression and relational aggression. The participants were 173 preschool children and their mothers from three day care center and two kindergarten in Seoul and Gyeong-gi province. The data were analyzed using descriptive statistics, t-test, correlations, and multiple regressions. The results were as follows: (1) There was statistically significant gender difference in preschool children's overt aggression, but there was statistically no significant gender difference in preschool children's relational aggression. Boys displayed more overt aggression than girls. (2) Preschool children's emotional regulation and activity explained children's overt aggression and relational aggression. When preschool children expressed more emotional regulation, they showed less overt aggression and relational aggression. Preschool children, who perceived having more activity from mothers, diaplayed more overt aggression and relational aggression. Gender was found to affect preschool children's overt aggression.
