This paper empirically examines the relationship between inter-Korean trade and inter-Korean relations over the past three decades. It asks two questions: (1) Does inter-Korean trade contribute to improved inter-Korean relations and peace on the Korean Peninsula? (2) Does improved inter-Korean relations lead to increased inter-Korean trade? The study employs a time-series causal relationship analysis methodology to answer these questions. The findings show that during the progressive government's reign, inter-Korean trade was not impacted by inter-Korean relations. This is due to the implementation of a political-economic separation policy towards North Korea. Moreover, the increase in general trade and processing on commission did enhance inter-Korean relations, reflecting the "inclusive policy" aimed at achieving peace on the Korean Peninsula through inter-Korean trade. In contrast, during the conservative government's reign, inter-Korean relations had a direct impact on inter-Korean trade, with deteriorating relations leading to a significant decrease in trade. This was due to the implementation of North Korea policies that were linked to politics and the economy.

This paper deals with inter-relationship change of women's university students on the process of SW development project using social collaboration tool. Inter-relationship is one of the basic vocational competency in NCS(National Competency Standards) of Korea. We redesigned the curriculum of "Software Engineering" subject for this study and composed the project teams of students to develop software. The details of inter-relationship are satisfaction, communication, faith, friendliness, sensitivity, openness and consideration. From the result of this study, faith, openness and consideration have positive effect but satisfaction, communication, friendliness and sensitivity have no meaningful effect. The surveys were conducted in the beginning of semester and the same surveys were conducted again in the end of semester. The results were verified by paired t-test with SPSS 18.0. It is significant that the using of social collaboration tool for team project has positive effect on inter-relationship change, especially faith of women's university students. This study has some limitations for generalization but has meaning as new trial to enlarge the basic vocational competency of students in major subject, "Software Engineering". We expect new study for inter-relationship change of students to evaluate generality based on the proposed method in this paper.

Recognizing the significance of inter-firm cooperation for firm's sustainable competitive advantage in today's business environment, this study investigates the effects of inter-firm cooperation and knowledge sharing on firm competitiveness based on 327 Korean small and medium sized enterprises. We also examines a mediating effects of knowledge sharing on the relationship between inter-firm cooperation and firm competitiveness and moderating effects of environmental factors on this relationship. The environmental factors are conceptualized by intensity of market competition and technological change. The main findings of the study are as follows: First, the paper found that inter-firm cooperation was positively associated with firm competitiveness while there was also a positive relationship between knowledge sharing and firm competitiveness. Second, it also shows that knowledge sharing partially mediated the relationship of inter-firm cooperation and firm competitiveness. Third, we also found that technological change had negative moderating effects on the relationship between inter-firm cooperation and firm competitiveness. This study suggests that understanding of inter-firm cooperation with consideration of environmental characteristics are required for better firm competitiveness.

The purpose of this research is to introduce the concept of "relationship formation factors" in inter-firm relations and to empirically demonstrate that they are effective in improving the relationship results by means of anmediating variable. Therefore, the basic model of this study consists of the independent, mediating, and dependent variables. First, the independent variable, that is, the relationship formation factors, is further classified into three components： transactional, relational, environmental characteristics. Then, the study empirically examines how each of the three components influences the dependent variable, that is, the business performance(Load Factor), by way of the mediating variables, that is, trust and relationship commitment.

In this paper, we drew upon IMP group's Interaction model to investigate the contributing impact of Inter-organizational system (IOS) on performance through enhancing inter-organizational relationship. While most extant literature studied the contribution of IOS from transaction efficiency perspective, the relational aspect of IOS contribution on the supply chain was addressed only by a few researches. As such, we intended to fill this gap of the IOS research stream. The conceptual model was developed, with reference to process theory, to analyze how the relational perspective could be applicable to IOS impact on performance. With the 129 sample data collected at the firm level,structural equation model using the LISREL was employed to validate the proposed research model. The empirical results supported the hypotheses such as the extent of IOS usage positively influences the interaction between the firms, which thereby enhances the extent of inter-firm partnership and performance. The results help better understanding the strategic use of IOS from relationship perspective.

I. OBJECTIVES The aim of this study lies in examining following items: 1. Difference in creativity between boys and girls 2. Inter correlation of the sub-variables of creativity 3. Correlation between parent-child relationship and creativity 4. The relationship between creativity and number of siblings 5. Creativity and birth-order II. METHODS & PROCED URES 1. Instruments: Standardized Creativity Test and Parent-Child Relationship Test for children 2. Objects: 118 boys and 97 girls enrolled in primary schools in Seoul who were selected by random sampling 3. Procedure: (1) The data of the boy group and the girl group were analized by means of M,t, SD. (2)The relationships between creativity and the number of siblings as well as the relationship between creativity and birth order were analyzed by M. (3) Inter-correlations among the sub-factors of creativity were obtained in boys and girls. (4) Complex-correlations between creativity and parent child relationship were produced. III. RESULTS 1. There were no significant differences between boy and girl in creativity. 2. Inter correlation among the sub-factors of creativity Boy: The highest scores were obtained in fluidity, and adaptability, the lowest in originality and openness. Girl: The highest score were obtained in world scribbling and fluidity, the comparatively low were in originality and a match-problem. 3. Inter-correlation between creativity and parent-child relationship a. Father-son: The positive refusal type has the most significant relation and conflict type, discrepancy type, negative type in turn have significant inter-coorelations. b. Mother-son: Discrepancy type, conflict type, positive refusal type have high correlations, while negative refusal type, anticipation type, and anxiety show significance in 5% level. c. Father-daughter: Positive refusal type shows correlation of 5% level significance, while indulgence type shows negative correlation in 1% level significance. d. Mother-daughter: Discrepancy type shows 5% level significance, while indulgence type shows negative correlation in 1% level. 4. Concerning the number of siblings, it was found that, boys and girls alike, those grown among 3 or 5 showed most creativity. 5. Concerning the birth order, it was found that, boys and girls alike, the first child showed the most creativity, and the youngest showed the next to the most, while the middle showed the least creativity.

This study is conducted to provide empirical evidences which support that the problems of social isolation and loneliness of elderly can be alleviated by intervening the inter-generational relationship of the elderly by means of active ageing policy. The major empirical challenge to address this question is the possibility of selection bias caused by reversed causal relationship. To address this challenge, I constructed comparison group with 'Eligible Non-Participants' (ENP), and used instrumental variable method to estimate the empirical model. My findings indicate that inter-generational relationship, both in the aspects of economical solidarity and associational solidarity, is significantly improved as time use pattern of the elderly becomes more active. The improvement effect is intensively observed for the group of elderly who do not live with their adult children. The important policy implication of these findings is that the improvement of inter-generational relationship can be added as a new benefit of active ageing policy.

The aims of the present study are firstly to investigate the amount of bone loss around non-submerged implants placed in the posterior region and secondly to investigate the relationship between inter-implant and implant-tooth distance and peri-implant bone loss. Thirty-one subjects with 60 implants were selected consecutively from the implant patient pool at the department of Chonbuk National University Hospital. To be included in the study subject, the implant should have been functioned more than 6 months after loading. Inter-implant and implant-tooth distance, distance between implant shoulder and the first bone contact with the implant(DIB) were measured from the scanning image of the radiograph of each implant. The result showed that; 1. inter-implant distance has a statistically significant relationship with DIB in Pearson correlation analysis. 2. the DIB at the implant facing surface of the implant was greater than that of tooth facing surface of the implant. Within limitation of this study, it is suggested to place an implant not too closely to adjacent implants, and the presence of a tooth adjacent to an implant may keep the level of tooth-facing surface of the implant. Further studies with a prospective design are needed to elucidate the relationship between bone changes and various dimensions around implants.

This research examines the effect of the relatedness and the gap between Resources and mechanisms on effectiveness of inter-organizational knowledge transfer. According to the literature, there has been a competing theory between two claims; one is that inter-organizational knowledge transfer will be more effective due to the reduction of the transaction cost as the relatedness increases. And the other is that the mutual complementarity of different organizational characteristics will increase synergy. In total, the relatedness and the gap of the Resource and mechanism makes the inverted U-shaped relationship with the inter-organizational knowledge transfer. As the result of empirical analysis about 109 Korean-based Joint Ventures entered country, it shows that the relatedness of parent company's production Resources, learning mechanisms, and coordination mechanisms made the inverted U-shaped relations with the inter-organizational knowledge transfer and the gap of production Resources and adjustment mechanism formed the same relationship. However, the U-shaped relationship has been established in the relatedness of market Resources, but the gap of market Resources and the learning mechanism was not statistically significant. Through this study, I can draw a best conclusion that the inter-organizational knowledge transfer will be more effective when the relatedness and the gap of management resources and mechanisms is in optimal level. However, when it comes to market Resources, it can be inferred that the result could be the opposite because the partner country's market environment would be different.
