Non-ideological information exchange and cooperation based on the scholarly and cultural fields would be the most effective project of south and north Korea for gaining the national homogeneity and trust in the long-term perspective. In this context, this study researched the measures on cultural exchange and cooperation between south and north through national libraries for the unified Korea. Related with that issue, this study analyzed function and limitation of national library in north Korea and evaluated library cooperation between south and north Korea in the frame of cultural cooperation project. So, this study suggested the stepwise model of the library cooperation between south and north based on the five practical measures including the cooperation governance system.

The purpose of this study is to provide academic and practical implications through empirical analysis on the moderating role of SHRM that is relatively lacking in the relationship between CLMRC and performance. In order to achieve the research purpose, data were collected from 123 CEOs of Korean companies. The reliability and validity of the collected data were examined and the hypothesis was verified by hierarchical regression analysis. The results of this study show that CLMRC has a meaningful positive(+) effect on both net profit and sales per person, and SHRM has shown to have a moderating effects between CLMRC and sales per person, CLMRC and net profit. Through this analyzes, CLMRC can enhance the management performance, and in this process, the more strategic the human resource management(HRM) is, the more the impact on the management performance is strengthened. Implications for CLMRC and SHRM, limitations of the study and suggestions for future researches are discussed.

In this paper, we propose coordinated scheduling and beamforming based on limited feedback to overcome the effects of inter-cell interference in multi-cell environment. The goal of this study is to improve a performance of cell-edge area significantly affected by the inter-cell interference and also to guarantee a performance of the entire system. Existing coordinated scheduling and beamforming based on the perfect channel state information generates an overhead for the channel state information feedback and exchange at the users and base stations, respectively. In this study, first we propose a novel codebook to obtain a null space of an interference channel efficiently which can be used to reduce the inter-cell interference. Using the proposed codebook, we propose coordinated scheduling and beamforming to improve the performance of cell-edge area and the entire system. Through the proportional fair scheduling, the performance of the proposed technique is shown as improvement of channel capacity for users located cell-edge area and entire system.

Labor-management relations are essential to corporation to secure competitiveness and a continuous development. However it is difficult to establish labor-management relations. This study focuses on the effect of cooperative industrial relations in trust and commitment of organization and labor union through 300people of 12 companies who belong to the Korean Confederation of Trade Unions. As a result of the study, cooperative industrial relations have a positive effect on the trust in organization and labor-management. Furthermore, the trusts of both organization and labor-management relations have a positive effect toward its commitment. This research result is an important factor to change a strategy of the labor union which cannot break out original roles. The cooperative industrial relations are also necessary for organization.

This study aims to look into factors which exert an important effect on the formation of cooperative employer-employee management systems of enterprises and finally to suggest an alternative for establishing the future's union-management relations. To accomplish the purpose, this research find each of important factors of the formation of cooperative employer-employee management systems through a theoretical consideration of those factors. The importance and priority order of the factors were systematized by the AHP analysis. The analysis showed the following two things. First of all, the management expecting the employees should be strengthened. Then, the establishment of transparent management and union-management systems sharing the enterprise's vision and values play important roles in the formation cooperative employer-employee management systems. In conclusion, this study provided alternative for establishing the future's union-management relations, based on the analysis results.

The purpose of this study is to investigate the impacts of Collaborative Problem solving for Character competency (CoProC) strategy on the practical character competency and collaborative problem solving competency in middle school. For this study, 49 seventh grade students (two classes) were selected for use applying the CoProC strategy (CoProC group) while 46 students (two classes) were used for traditional lecture and experimental class (comparative group). In the result, CoProC group showed a statistically significant result in practical character competency than the comparative group. In the sub items of the competency, the CoProC group showed result statistically significant in cooperation, communication, responsibility, and positive self-understanding than the comparative group. Analysis of the effect size of students' practical character competency showed that the CoProC group results showed more effective than the comparative group in terms of care, cooperation, communication, honesty, responsibility, positive self-understanding, and self-regulation. In addition, we investigated the effect of the CoProC strategy on collaborative problem solving competency. As a result, it showed a large effect in the total score of collaborative problem solving competency. Among the sub items of the competency, 'exploration and understanding of members' showed a small size of effect and 'Establishing and maintaining team organization' showed a medium size of effect. 'Communication' and 'self-reflection' showed a large effect. CoProC strategy embedded in Science subject could improve students' collaborative problem solving competency through the process of scientific communication in the scientific inquiry process.

협력적 추천 알고리즘의 성능향상을 위한 많은 연구들이 진행되고 연구 결과로 다양한 협력적 추천 기법들이 제안되고 있다. 이러한 연구에서는 EachMovie, MovieLens등의 선호도(Rating) 값을 기반으로 하는 데이터를 대상으로 추천의 효율을 높이고자 하고 있다. 그러나 실세계에서 우리가 얻을 수 있는 원 거래 데이터(Raw Transaction Data)는 선호도 값을 갖고 있지 않다. 따라서 실세계의 구매 데이터에 효과적인 추천을 하기 위해서는 기존의 선호도 기반 알고리즘이 아닌 구매 정보만을 기반으로 하는 변경된 협력적 추천 알고리즘이 필요하다. 본 논문에서는 연관규칙 탐사 기법에서 사용하는 확신도(confidence)를 유사도식에 사용하고 이를 기반으로 선호도를 예측하는 구매 기반의 협력적 추천 알고리즘을 제안한다.

우리가 크게 의존하고 있는 미국의 기술이전 기피추세는 우리의 방산국제협력을 제약하는 요인이 되고 있는 반면에, 세계적인 군비축소에 따라 세계무기시장에서 선진공급국간의 경쟁심화는 우리에게 유리한 방산협력기회를 제공하고 있습니다. 변화된 국제협력여건하에서 방산국제협력을 효율적으로 추진하기 위해서는, 안보.경제.기술.통상 등의 제 요인을 고려한 협력 국가간 상호 호혜적인 협력의 중요성을 인식하고 중장기적인 방산국제협력 목표와 전략의 수급이 요구됩니다

This study is a preliminary work in examining how to manage resources for collaboratively interactive help systems. The purpose of this article is to describe significant patterns of behaviors and cognitive state in collaborative problem-solving situation, and further to explore the relationship between the behavior and the perception of service evaluation. Based on the concept of 'cognitive motion' in Dervin's Sense-Making theory, this study conducted a time-line interview. The sample of this study consists of 22 IT personnel helping other person solve IT problems and 36 users being helped for a IT problem-solving. This study presents a model of collaborative problem-solving behaviors and discusses some implications for designing help systems which collaborative interactions can happen.
