Views are essential in providing logical data independence for database systems. Object views in object-oriented/object-relational databases have requirements quite different from those of relational databases due to support for object-oriented concepts. Although many commercial object-oriented/object-relational database systems support object views, implementation techniques have not been discussed sufficiently in the literature. In this paper, we devise a technique for implementing views in object-oriented/object-relational databases and apply it to the ODYSSEUS object-relational database system. We first analyze the requirements of object views. Next, to implement object views, we extend the existing query modification algorithm that has been proposed for implementing views in relational databases. Next, we compare the features of the proposed object view with those of object views in commercial object-relational database systems. It is shown that the proposed object view supports all object-oriented concepts such as object identifiers, inheritance, methods, and composite objects, while existing object views support part of them. Last, we propose detailed techniques for implementing the extended query modification algorithm in the ODYSSEUS object-relational database system.

The major purpose of this study was to explore the relation of a child's need for approval, anxiety and anger-in on a child's relational aggression according to gender. The study's participants included 464 boys and girls selected from fifth-and sixth-graders at an elementary school in Busan. A child's need for approval, anxiety, anger-in and relational aggression were assessed with their own self-reports. For data analysis, Cronbach ${\alpha}$, T-test, Pearson correlation coefficients, and Multiple Regression were used. The collected data was analyzed by the SPSSWIN 18.0 program. The major findings were as follows: First, child's anger-in demonstrated a significant difference among sexes. Girls indicated higher points than boys. Second, Boys' need for approval indirectly affected child's relational aggression through anger-in. Boys' anger-in was directly affected by relational aggression. Boys' anxiety was directly affected by anger-in. And boys' anxiety indirectly affected child's relational aggression through anger-in. Third, Girls' anxiety was directly affected by relational aggression. Need for approval and anxiety were directly affected by anger-in. The findings from this study indicates that child's need for approval, anxiety and anger-in are important elements in relational aggression are affected differently depending on the child's gender. Also, this study has meaning in that it can be used as fundamental data to develop a teaching plan and counseling program for children that can decrease relational aggression.

The primary purpose of this research is to develop and test a model that explains the process of how trust in a supplier firm and salesperson through relational commitment influence buyer's positive and desirable behavior. In order to do so, we are empirically to examine how a supplier firm and salesperson trust can reinforce buyer's relational commitment leading to relational citizenship behavior using over 138 buying firms, Through structural equation modeling, we find that trust in a supplier firm and salesperson influence the relational commitment and relational commitment enhance relational citizenship behavior. However, trust in a supplier firm is unrelated to the buying firm's relational citizenship behavior whereas trust in salesperson has direct effect on relational citizenship behavior. Finally, we discuss several theoretical and practical implications, and suggest limitations for the research and future research issue.

This paper examine the roles of social rapport and friendship which are the representative variables of strong emotional bonds between customers and firms in service relationship marketing. As results, social rapport and friendship were confirmed as positive moderators between a relational antecedent variable and a relational mediator variable. In other words, emotional bonds, such as social rapport and friendship, stimulated relationship development in service relationship marketing. Meanwhile, customer-firm emotional bonds seemed to be a negative effect on the stage of a relational mediator variable and a relational outcome variable. This meant that relational mediator variable and emotional bond variables(social rapport and friendship) individually had an positive effect on a relational outcome variable. If emotional bonds between customers and firms had already built, they could have positive influence on the relational outcome, regardless of relational mediator variables. Conclusively, firms' relational efforts focus on the building the emotional bonds with customers, not on the process of relational antecedents, mediators, and consequences.

This study attempted to investigate the impact of relational characteristics just like level of perceived communication, support, conflict and justice between optical franchisor and franchisees on relational performance. Data collected from A Optical Franchisees supported two hypotheses such as communication and relational satisfaction, relational satisfaction and long-term commitment that were proposed. Another result between justice and relational satisfaction in this study shows that the other research and interpretation for this phenomenon was attempted. In accordance with the results, the following conclusion was made: it is very important to communicate with franchisor, and the core mean for that would be the enhancement of the long-term commitment of franchisees through the perceived relational satisfaction of franchisee's in optical franchise system. To accomplish this, to understand characteristics of franchisor and franchisees and fit of their characteristics should be preceded.

In this paper, we present a method to solve a convexly combined fuzzy relational equation with generalized connectives. For this, we propose a neural network whose structure represents the fuzzy relational equation. Then we derive a learning algorithm by using the concept of back-propagation learning. Since the proposed method can be used for a general form of fuzzy relational equations, such fuzzy max-min or min-max relational equations can be treated as its special cases. Moreover, the relational structure adopted in the proposed neurocomputational approach can work in a highly parallel manner so that real-time applications of fuzzy sets are possibles as in fuzzy logic controllers, knowledge-based systems, and pattern recognition systems.

Since XML emerged as a standard for data exchange on the web, it has been widely used for applications like e-Commerce, CRM, and BI. However, it is common that most of business data is stored in relational database systems, and it is expected that business data management would still be centered around the relational database systems. As such, the technique of viewing relational data as XML and processing XML queries against it is required. To meet such a need, in the SQL/XML standard, the functions to publish relational data as XML are provided. In this paper, we propose the techniques of providing an XML view of relational data defined by an SQL/XML statement in DTD(Document Type Definition), and of processing XPath queries against the XML view by translating them into SQL/XML statements, and describe the validation of such techniques through implementation and tests.

The purpose of this study was to describe and understand the characteristics of morphological, contextual as relational aggression among 4-year old children during free play periods. The ethnographic methods included participants observation of children's play interaction behaviors, field notes, video taping and analysis of transcribed date. The results are as exclusion occurred by group power taking the relational attribute, including direct language, while the other would not be revealed easily other than being in line with real relation. Also as follows; proactive relational aggression was more frequently observed in girls, and their major strategies employed against someone they disliked were ignoring them, distorting play-rules, and so on. Major strategies of reactive relational aggression in girls were largely manipulative in nature, for example, 'threatrning their friend' and 'withdrawal of friendship'.

The purpose of this study was to interpret relational aggression strategies in 4 year old young children's interactions in 'Sansae class' in terms of two-fold dimensions of proactivity and reactivity. Following an ethnographical approach, participative observation on young children and in-depth interviews with the teacher were employed, over the course of 30 sessions of 3 hours duration. The results are as follows; proactive relational aggression was more frequently observed in girls, and their major strategies employed against someone they disliked were ignoring them, distorting play-rules, and so on. Major strategies of reactive relational aggression in girls were largely manipulative in nature, for example, 'threatening their friend' and 'withdrawal of friendship'.

We propose an XML document storage system, called XDMS (XML Document Management System), by using an object-relational DBMS. XDMS generates object database schema from XML Schema and stores the XML documents in an object-relational database. SAX parser is used for understanding the structure of the XML documents, and XDMS transforms the documents into objects in the database. Experiment shows that object-relational databases provide more efficient storage and query model compared with relational databases.
