과거 독립적으로 운영되던 이동통신망과 유선인터넷망이 유무선 통합 서비스의 확대로 상호간의 트래픽이 교환되고 있고 기존의 유선 콘텐츠와 연계된 다양한 서비스들이 등장하고 있다. 현재 이동망과 유선망의 데이터망 간의 트래픽양이 많지 않지만 향후 망 개방 효과의 확대, 유무선 통합서비스 활성화, 통신서비스의 진화에 따라 트래픽 증가에 따른 처리에 대한 유선과 무선 사업자간 상호접속과 관련된 다양한 이슈가 발생할 것으로 예상된다. 본 논문에서는 이동통신망과 유선인터넷망 간의 데이터망 상호접속 현황 및 연동에 따른 수익구조 관계를 분석 한다. 또한 유무선 연동 구조의 가치체인과 관계 사업자를 분석하고 무선인테넷 요금제 유형에 따라 이동통신사, 유선계 사업자, 콘텐츠 사업자 중심으로 상이하게 나타나는 이해관계를 분석하고자 한다.

Utilizing fit theory in strategic human resource management, this study examines the impact of two HR practices on newcomer turnover rates. While there is a growing body of research identifying the linkage between high-performance work systems(HPWS) and improved organizational performance through higer employee commitment, little research addresses how specific mechanisms among the systems deliver different performances to organizations. Using management by objective(MBO) and job rotation in HPWS, we found a strong main effect of each practice-it decreases newcomer turnover rates. This main effect becomes stronger when one practice combined with another, showing synergy exists. Linking HPWS research to turnover, this study provides insightful evidence of interactions between MBO and job rotation for organizational performance.

The purpose of this study was to examine the effect of job-demands on social worker's organizational commitment. Espically this study focused on the moderating effect of LMX between job-demands and organizational commitment. The sample consisted of 189 social workers in 33 Senior Welfare Centers. The date was analyses using descriptive and multiple regression methods. The major findings of the study firstly were job-demands had negative effect on the social worker's organizational commitment and LMX had positive effect on the social worker's organizational commitment. Secondly, LMX had mederating effect between job-demands and organizational commitment. All these findings were discussed on Social Welfare Center and research.

The purpose of this study is to review the relationship between transformational leadership(charisma, individual consideration, intellectual stimulation, inspiration) and knowledge management, and the moderating effect of social(trust and interaction) in small business. In order to verify and achieve the purposes mentioned above, questionnaire data are gathered and analysed from 311 subjects in Kangwon-do province. Multiple regression and multiple hierarchical regression analysis were applied to test these hypotheses: 1) the relationship between transformational leadership and knowledge management, 2) the moderating effect of trust on the relationship between transformational leadership and knowledge management, 3) the moderating effect of interaction on the relationship between transformational leadership and knowledge management. Empirical survey's findings are as follows; First, individual consideration and inspiration leadership appeared to be positively related with all knowledge management(knowledge creation, transfer, application). Second, charisma was verified to be positively related with knowledge creation only. Third, charisma and inspirational leaderships were more positively with knowledge creation in higher trust group than in lower trust group. Fourth, intellectual stimulation and inspirational leaderships were more positively with knowledge creation in higher interaction group than in lower interaction group. Fifth, individual consideration was more positively with knowledge application in higher interaction group than in lower interaction group.

In this paper, we exmined the effect of leaner-tutor interaction model implemented in a Web-based virtual education system. Also, we proposed a new tutor model as a strategy for solving problems found in learner-tutor intraction in Web-based virtual education. Then, based on the results of previous research, we derived the roles of the tutor, and using the roles, modeled components of interaction between the tutor based on existing Web-based virtual education systems to demonstrate the effect. The results showed that the proposed model is efficient for improving the learners' achievements and interactive activities.

지휘통제, 전략전술, 물자관리 등 다양한 분야에서 사용되는 국방정보시스템들은 필요에 따라 원활하게 상호운용 되어야 군 정보화 효과를 극대화할 수 있다. 이 논문은 정보시스템 상호운용 수준(LISI)에 의거해서 국방정보시스템 간의 상호운용 능력을 전자설문 방식으로 측정하고 테스팅을 통해서 확인하는 기법을 제시한다. 제시된 전자설문 기법은 구현옵션 집합과 질의문을 이용해서 정보시스템 간의 잠재적 상호운용 수준을 측정한다. 반면에 테스팅 기법은 전자설문을 통해서 결정된 두 정보시스템 간의 잠재적인 상호운용 수준을 분산 소프트웨어 테스팅 기법을 사용하여 실질적으로 측정한다. 마지막으로 제시된 전자설문 기법과 테스팅 기법을 바탕으로 개발된 상호운용성 평가도구를 소개하고 적용결과를 제시한다.

There has been a claim that Interaction between the cerebral hemispheres could reduce the effect interfering information (Weissman & Banich, 1999). We ran three experiments to show that between-hemisphere separation of target and distractor could be more effective for reducing interference than Interaction between the hemispheres. In experiment 1, a colored box and a rotor name were presented to a single or to separate hemispheres. In experiment 2 and 3, a colored circle (distractor) was presented along with a colored box and a color name which was always printed in black. In experiment 3, a peripheral cue was presented either to the target location(66.7%) or to the distractor location(33.3%) Immediately before the presentation of stimuli. In all experiments, the participants were asked to deride whether the moaning of the color matched the rotor of the box, Ignoring the printed rotor of the word(Exp. 1), or the color of the circle(Exp. 2 & 3). There were three renditions of distractor (congruent, incongruent, and neutral) and two conditions of matching (between- and within-hemisphere matching). If interhemispheric interaction were effective for interference reduction, there should be a decrease in the interference in the between-hemisphere compared to the within-hemisphere matching condition. The results showed that there was no difference in the interference between the two matching conditions in Exp 1. In Exp 2 and in the target-cue renditions of Exp. 3, the amount of interference in the between-hemisphere condition was greater than that in the within-hemisphere condition. These findings are consistent with what we have previously reported (Sohn et al., 1996, Sohn & Lee, 2003). However, when the distractor was precued in Exp. 3, the amount of interference did not differ between the two marching conditions. These results suggest that between-hemisphere separation of target and distractor can be more effective for reducing response interference than interhemispheric communication. It implies a possible role of an interhemispheric shielding mechanism (Merola & Liederman, 1985) to prevent the transfer of task-irrelevant, harmful information across the hemispheres.

This study investigates the interactivity of smart LMS. To this end, smart LMS was used for one semester in the English course for economics majors and the surveys about its interactivity were conducted. The findings show that smart LMS enhanced the interaction between instructors and students, between students and students, and between students and learning contents. Especially in the classroom, the activity bulletin made possible the instructor's immediate feedback about team-based activity outcomes. Also, outside the classroom, Wiki made it convenient for students to collaborate with each other. In addition, activity outcomes in the activity bulletin and course materials uploaded on smart LMS contributed to the interactivity. However, what is recommended to do to increase the interactivity are to prepare instructional strategies for students to get used to using smart LMS and smartphones as their learning tool, to test the target systems of smart LMS in advance, and to take proper actions to solve the problems of smartphone's data and battery.
