본 연구에서는 우리나라 234개 상장기업을 대상으로 기업의 소유구조와 자본구조의 상호관계가 기업다각화에 미치는 영향을 2단계 최소자승법(2SLS)을 이용하여 분석하였다. 우리나라 기업의 소유구조와 자본구조의 상호관계를 분석한 결과를 요약하면 첫째, 1996년부터 1999년까지의 전기간 분석에서 우리나라 기업은 소유구조와 자본구조 정책을 서로 연계하여 결정하는 것으로 나타났다. 그러나 IMF 경제위기 전후기간으로 구분하여 상호영향관계를 분석한 결과에 의하면 IMF 이전기간에는 소유구조와 자본구조가 상호의존적인 영향관계가 있는 것으로 나타났지만, IMF 이후기간에는 소유구조와 자본구조의 상호영향관계를 발견할 수 없었다. 둘째, 내부자는 부채사용에 따른 재무위험의 부담을 줄이기 위해 레버리지 비율이 높으면 내부지분율을 감소시키는 것으로 나타났다. 넷째, 내부지분율이 높으면 내부자는 자신이 부담해야 하는 재무위험을 줄이기 위해 레버리지 비율을 낮추는 것으로 분석되었다. 한편, 소유구조와 자본구조의 상호관계가 기업다각화에 미치는 영향을 분석한 결과에 의하면, 소유구조와 자본구조의 상호관계가 기업다각화 수준에 영향을 미치지 않는 것으로 나타났다.

As interdependence and conflict are important to the understanding of channel interactions, many researchers have studied their relationship. Identifying the relationship between interdependence and conflict will help understanding an exchange relationship. In social science, the relationship between interdependence and conflict is explained by two contradictory theories, and there are also inconsistent results in marketing science. The authors suggest non-linear relations between asymmetric interdependence and conflict, based on bilateral deterrence theory and conflict spiral theory. Using survey data from industrial market, we demonstrate that there is an inverted U-shaped relationship between asymmetric interdependence and interfirm conflict. The result show, as the magnitude of interdependence is high. the hypothesis on the non-linear relationship between asymmetric interdependence and conflicts is acceptable on both suppliers and distributors. Finally, we discuss several theoretical implications and suggest limitations and future research issues.

The purpose of this study was to examine the relations between the quality of teacher-child relationship, child temperament, and teacher-child interaction. The subjects were 51 3-4 years old children who were attending a preschool in Seoul and their mothers. The mothers of the young children rated child temperament and the head teachers of the children evaluated the quality of teacher-child relationship. The frequency of teacher-child interactions in the classroom was collected through observation during self-selected activities in the classrooms. Observational data included frequency of teacher-initiated interactions and number of child-initiated interactions. The results showed that boys were more likely to have conflictual relationships with teachers and girls were likely to have close relationships with teachers. And lower levels of effortful control were associated with teacher-child conflict. More child-initiated interactions were related to the conflict relationships with teachers. Results suggest that child characteristics and teacher-child interactions contribute to children's relationships with teachers.

The purpose of this study was to investigate how children's temperament and relationships with teachers affect their peer interaction. For this purpose, two surveys were conducted on mothers and teachers of 326 four- and five-year-old children attending four kindergartens in Gyeonggi Province. The data were analyzed by using PASW 18.0 to carry out hierarchical regression and post hocanalyses. The results showed that closeness to teachers moderated the effects of children's emotionality on their positive peer interaction. On the other hand, children's temperaments including emotionality and activity, and their relationship with teachers were directly influential on their negative peer interaction; no interaction effect was found between their temperament and relationships with teachers. It was concluded that the quality of teacher-child relationships could promote children's positive peer interaction while it could also reduce their negative interaction with peers. However, the temperament of children played limited roles in their negative peer interaction.

This paper suggests a method for verification of temporal relations on SMIL 2.0 document using an extended temporal interval model. The SMIL 2.0 document has more asynchronous temporal relations and supports more interactive relations between objects than traditional SMIL document. But it is higher to produce temporal inconsistency by various interactive relations between objects. So the suggested verification method expresses SMIL 2.0 document as functional relations based on an extended temporal interval model and verifies SMIL 2.0 document using interactive relations and temporal intervals between objects. Applications to the verification method are as follows; multiuser interactive contents, online-learning, etc.

This study investigated the relationships of preschool children's interactive peer play, stimulated home environment, and mother-child interaction. A total of 255 children were selected in this study. Data were analyzed with Pearson correlations and covariance structural analysis by using SPSS and AMOS, a statistical program for structural equation modeling. The major findings of this study were as follows: First, interactive peer play was associated with stimulated home environment and mother-child interaction. Second, the results confirmed the pathway from stimulated home environment via mother-child interaction to interactive peer play showing a significantly good model fit. The paths from stimulated home environment to children's interactive peer play were mediated by mother-child interaction.

As mentioned on the paper, this study does not tackle the issue of contention about different media mix. It rather analyzes the capability and intensity of new media created through the correlation of different media, and researches the intermediality relationship among media to create new type of fine quality media. Along with the development of digital technology, the intermediality relationship among painting, video media such as movie and animation has become active. Also, as the study examined, the mix of 'painting and movie', 'movie, animation, game' has blurred the boundary, and formed a mutual inevitable relationship. Thus, this study examined the transfer of media and correlation based on intermediality relationship insisted by Rajewski and Deleuze's theory. Deleuze's theory explains the relationship of being which analyzed the variation of media. As for the intermediality relationship of media, the study examined process of media combining and converting based on 3 types of category of Rajewski, "media combination, media conversion, intermedial relationship matching".

The design of PN(Pseudo Noise) sequences with good cross-correlation properties is important for many research areas in communication systems. Also analyses of cross-correlation frequency between designed sequences have been researched. In this paper we analyze of cross-correlation distribution and properties of non-linear binary sequences family $S^r=\{Tr^m_1\{[Tr^n_m(a{\alpha}^t+{\alpha}^{dt}]^r\}{\mid}a{\in}GF(2^m),0{\leq}t < 2^n-1\}$, where $gcd(r,2^m-1)=1$ with 5-valued cross-correlation.

본 논문에서는 생물학적 실험에 의해 추출된 특정 종의 단백질 상호작용 관계를 다른 여러 종에서 이미 밝혀진 단백질 상호작용 관계들을 통해 검증할 수 있는 방법을 제안한다. 이 검증을 위해 기본적으로 요구되는 이종간 단백질들 사이의 상동성 관계는 Swiss Prot 데이터베이스의 모든 단백질들에 대해 이름 패턴, 키워드, 서열 비교를 통해 구축된다. 즉, 특정 종에 대한 단백질 상호작용 관계를 여러 종의 단백질 상호작용 관계들로 상동화하고, 이 상동화된 관계들이 각각의 종에 어떠한 형태로 존재하는지의 여부를 판단함으로써 검증된다.

현재 우리 나라 약업계에서는 의약분업, 일부 의약품의 슈퍼마켓에서의 판매 등의 급격한 환경변화로 약국경영형태의 혁신적인 변화가 진행되고 있다. 본 논문에서는 현재 약업계에서는 급속히 발전되고 있으나 학문적으로는 연구된 적이 거의 없는 볼런터리 체인형태의 협업체 약국에 초점을 맞추어 가맹약국과 체인본부와의 거래관계의 질과 체인약국 시스템의 효율적인 운영 및 관리방안을 알아보았다. 본 논문에서는 연구목적들을 달성하기 위하여 특정 협업체 약국체인에 참여하고 있는 168개의 가맹약국을 대상으로 자료를 전국적으로 수집하였으며, 구조방정식 모형을 사용하여 연구가설을 검정한 분석결과는 다음과 같다. 첫째, 약국체인시스템에 투자한 가맹약국의 거래특유자산과 기업가정신은 관계규범에 유의한 영향을 주었으나, 환경의 불확실성은 정보교환, 결속력, 운영유연성 등의 관계규범에 유의적인 작용을 하지 못하였다. 둘째, 거래특유자산과 동기적 투자는 체인구성원들간의 상호의존성을 유의하게 높였으나, 대체안의 획득가능성과 관계규범은 상호의존성에 중요한 영향을 미치지 못하였다. 마지막으로, 체인구성원간의 관계규범과 상호의존성이 관계의 질 즉 가맹약국들이 거래에서 느끼는 만족, 체인본부에 대한 신뢰, 약국체인에 지속적으로 참여하려는 몰입에 주는 영향을 분석하였다. 상호의존성은 관계규범과 신뢰에 영향을 주고, 관계규범은 만족을 통하여 신뢰에 유의한 영향을 주었으며, 그리고 신뢰는 몰입에 유의적인 영향을 주었다.
