One of the fundamental components important to the analysis of spatial objects is to represent topological relationships between spatial features. Users of geographic information systems retrieve a lot of objects from spatial database and analyze their condition by means of topological relationships. The existing methods that represent these relationships have the disadvantage that they have limited information in $R^2$. In this paper, we represent and define the topological relationships between 3-dimensional spatial objects using the several representing methods of 2-dimensional features. We use the diverse representing methods, which include the 4-, 9-intersection, dimension extended and calculus-based method. Furthermore, we discuss OGC's topological relationships and operators for 3-dimensional spatial data.

This study compared preadolescent communication skills and quality of peer relationships by institutionalization, sex, and age and tested the correlation between communication skills and quality of peer relationships. The subjects were 98 institutionalized and 115 homereared preadolescents. Interviews measured the communication skills of persuasive, comforting, and listener-adapted abilities. The quality of peer relationships was investigated through questionnaires consisting of both positive and negative factors. The data were analyzed by SPSS. Differences were found between institutionalized and homereared subjects in quality of peer relationships and in communication skills by sex, and age. There was a positive correlation between communication skills and quality of peer relationships.

This study explores how South Korean citizens evaluate corporate social responsibility (CSR) practices based on communal and exchange relationships. Specifically, it examines whether their evaluations of the two types of relationships are related to their supportive opinions, such as positive attitudes toward corporations and behavioral intentions to purchase products. The findings show that the communal relationship between an energy corporation and its local residents is more related to their supportive opinions than exchange relationship. That is, a communal relationship tends to generate more positive business outcomes than an exchange relationship. This study concludes that corporations should prepare for useful community outreach and CSR programs for their local community. Practitioners need to focus on building communal relationships with community members through their programs.

Objective: The purpose of this study was to examine the effects of parent-teacher relationships on mothers' parenting efficacy especially for toddlers. Methods: 225 mothers of toddlers completed questionnaires on parent-teacher relationships and parenting efficacy. This study used technical statistics, Pearson's correlation analysis, and multiple regression analysis in order to analyze the collected data. Results: First, there was a significant correlation between parent-teacher relationships and mothers' parenting efficacy. Second, the parent-teacher relationships was an important factor in predicting mothers' parenting efficacy. In particular, when a teacher and mother develop practical collaboration for caring for and educating a child, the mothers' parenting efficacy was higher. Conclusion/Implications: These findings indicate that the parent-teacher relationship is a significant factor in order to improve the quality of parenting. The results especially support the importance of collaboration between teachers and parents and suggest that we need to find practical ways for collaborating in the field. Limitations of this study and implications for future research were discussed.

In supply chains, collaboration between buyer and supplier can improve firms' ability of supply chains to their objectives and competitive advantages. A key factor in collaboration in supply chain is to identify buyer relationships and supply relationships as antecedents of the factor collaboration. We analyzed data collected from buyers and suppliers sampled from a mobile networks industry in Korea and found that the level of collaboration comes from strong relationships between two parties and the collaboration enhances the supply chain performances. However, buyer relationships and supplier relationships have indirect impacts on trading partners' performance through collaboration whereas both have direct impacts on one's performance. Therefore to enhance supply chain performances, supplier's operational efficiency and buyer satisfaction, firms of buyers and suppliers should consider pursuing practical and substantial collaboration along with buyer-supplier relationships.

The purpose of this study was to investigate how parental childrearing behavior and children's sibling relationships are related to children's self-esteem. 440 middle class families consisting of two children and their parents were the subjects of this study. The research instruments included a childrearing behavior questionnaire, the Sibling Relationships Questionnaire (Furman & Buhrmester, 1985), and the Self-Perception Profile for Children (Harter, 1985). Analyses of the data included correlation analysis, canonical correlation, regression, stepwise multiple regression, and MANOVA with stepwise discriminant analysis as the follow-up test. The most powerful predictors of children's self-esteem were the Warmth-Acceptance of childrearing behavior and the Warmth-Closeness of sibling relationships. The self-esteem dimension was best predicted by parental childrearing behavior and by children's sibling relationships was Global Self-Worth. Behavioral Conduct was best predicted by the Rejection-Restriction factor of childrearing, and by Conflict (for boys) and Rivalry (for girls) factors of sibling relationships. Children's self-esteem was related more strongly to the Warmth-Acceptance and the Rejection-Restriction of opposite-sex parents. The effects of Permissiveness-Nonintervention were stronger in same-sex parent-child dyads. Parental childrearing behaviors accounted for boy's self-esteem better than girl's with the exception of Behavioral Conduct. Sibling relationships accounted for girl's self-esteem better than boy's. The $2{\times}2$ MANOVA revealed interaction effects of parental childrearing behaviors and sibling relationships on children's self-esteem. Two factors of Rivalry and Conflict in sibling relationships and all three factors of childrearing behaviors showed significant interaction effects, The childrearing factor of Permissiveness-Nonintervention and the sibling factor of Rivalry, which were relatively weak predictors of self-esteem when acting alone, gained power in explaining children's self-esteem within the interactional context.

본청업체와 하청업체간의 관계는 본청업체의 압박으로 하청업체는 강한 종속감을 가지고 있다는 것은 여러 연구를 통해서 입증되어오고 있다. 이러한 관계의 대표적인 분야가 자동차산업이다. 하청업체의 본청업체에 대한 종속감은 여러 요인들이 있지만 특히 부족한 기술력을 들 수 있다. 이러한 연구 안에서 일반적으로 외국기업이 하청업체일 경우에도 같은 결과를 가지고 오는지에 대한 연구는 많지 않다. 본 논문의 연구목적은 외국기업이 하청업체이면서 본청업체가 한국기업인 경우에는 어떤 영향이 있는지, 그리고 그 요인 중에서 특히 R&D 센터를 한국에 소재하고 있는 경우에도 기존의 연구와 같은 결과를 가져오는지에 대한 분석이다. 제 2장에서는 이론적 배경으로서 본청업체와 하청업체간의 비즈니스 관계에 대한 일반적인 특징을 살펴보았다. 제 3장에서는 연구방법을 이어서 제 4장에서는 하청업체로서 대표적인 독일 보쉬 회사가 R&D센터를 한국에 주둔시킴으로써 본청업체와의 비즈니스 관계에 미치는 영향에 대해서 사례분석으로 다루었다. 마지막으로 제 5장에서는 한국정부에 주는 정책적 시사점 및 연구의 한계점을 제시하였다. 본 논문에서 사례분석을 통해서 살펴본 비즈니스 관계는 하청업체가 적극적인 R&D센터 활동을 통해서 본청업체와의 관계를 파트너관계로 발전시킬 수 있음을 볼 수 있었다.

Autonomous system (AS) business relationships and their inference have been widely studied by network researchers in the past. An important application of inferred AS relationships can be the prediction of AS paths between a source and destination AS within a model. However, besides knowing the topology and inferred AS relationships, AS path prediction within a model needs to be understood in order for us to know how we can derive border gateway protocol (BGP) policies from AS relationships. In this paper, we shed light onto the predictive capabilities of AS relationships by investigating whether they can be translated into BGP policies such that inferred AS paths are consistent with real AS paths, e.g., paths observed from BGP routing tables. Our findings indicate that enforcing constraints such as the well-known valley-free property and the widely assumed preference of customer routes always results in a very low consistency for AS path inference. In addition, this is true irrespective of whether customer, peer, or provider routes are preferred. Apparently, applying such constraints eliminates many "correct" paths that are observed in BGP routing tables and that are propagated in a simple shortest path model where AS relationships are ignored. According to our findings, deriving BGP routing policies for predicting with high accuracy AS paths in a model directly from AS relationships is still difficult.
