Effective internal communication is known to have a positive impact on business performance, but there is a lack of research on the effects of online channels for workplace communication. This study using regression analysis examines how task-technology fit, information richness, self-efficacy, perceived ease of use, and perceived usefulness related to online communication channels affect not only the satisfaction with the tools but also the effectiveness of them. Additionally, we verify how the organizational culture of online and offline communication shows the control effect. As a result, all five variables were positively correlated with internal communication channels satisfaction, and we found that the organizational culture of online and offline communication controls the relationship between online communication channels satisfaction and effectiveness.

미래전에서는 무기체계의 상당부분이 무인체계로 대체될 것이며 이들은 상호 통신으로 연결되어 네트워크중심전으로 변화하고 있다. 이에 따라 무인체계 효과분석이 중요한 이슈가 될 것이다. 하지만 무인체계의 주요통제 수단인 통신장애 상황에서 UGV에 대한 효과분석 연구는 매우 미흡한 실정이다. 본 논문에서는 지형을 고려한 통신장애 상황에서 무인체계의 운용효과분석을 위한 새로운 에이전트기반 모델링 절차를 제시하였다. 추가적으로, 통신장애 상황을 극복할 수 있는 통신중계기를 추가하였을 경우 UGV운용효과의 변화에 대한 분석결과도 제시하였다.

The purpose of this study was to investigate the relationships of early childhood teachers' communication ability, teacher efficacy, and organizational effectiveness of child care centers. The subjects of this study were 397 teachers working at child care centers. The results of this study were as follows. First, differences in the organization effectiveness of child care centers were detected according to teachers' age, career, type of child care center where they were affiliated, and marriage status. Second, the relative effects of the teachers' communication ability and teacher efficacy on the organizational effectiveness of early-childhood educational institutions differed significantly according to each sub-factor; teachers' communication ability's sub-factors - response, analysis, and evaluation - and teacher efficacy's sub-factors - general efficacy and personal efficacy - had partial effects on the organizational effectiveness of child care centers. Of these, personal efficacy had the greatest effects on all sub-factors of organizational effectiveness. This study is significant since it identifies the variables that could affect the organizational effectiveness of child care centers.

Purpose: In this research, we develop an effectiveness analysis simulation model using Agent Based Modeling with Communication Effects for the development of a new weapon system. Methods: To describe the future battlefield that has more complexity, we develop Agent Based Modeling to describe communication Effects. We use the communication theory (Path-Loss Model) and the real map. Results: We have compared simulation model with real map and simulation model without real map. The Blue Survival Ratio of simulation model with real map is worse than one without real map since the performance of communication gets lower. Conclusion: There are many studies about the effectiveness analysis of a weapon system. Most of previous researches assumed no communication error. In the real world, however, it's not appropriate assumption. Therefore, this study considers the communication error and shows that it is important factor in the effectiveness analysis.

Purpose: In the near future, it is expected that UGV(unmanned ground vehicle) will be put into battle due to IT technology and unmanned technology development. In this study, we analyze the combat effectiveness considering communication effect where complex combat information and commands are transmitted. Methods: We use ABM(agent-based modeling) and wireless channel module which provides sophisticated communication effect through geographic information and UGV performance. And UGV combat simulation using wireless channel module is used to grasp the combat effectiveness according to the number of packets, which is a unit for storing all information and commands having high complexity. Results: The result of this study is to derive the optimal number of packets which does not decrease the combat effectiveness and the number of lost tanks. The number of packet increases, the survival ratio of our tanks are decreased. Conclusion: In this study, we reveal that the communication success or failure could affect the combat effectiveness. Also, it helps develope the standard communication protocol between UGVs and could be applied to analyze the cost effectiveness analysis in UGV combat environment.

본 연구의 목적은 기업 및 공공기관의 교육훈련 참여자 특성을 팔로워십, 공동체의식, 성실성으로 구분하고 이들 특성과 조직유효성과의 영향관계를 규명하는 것이며, 또한 커뮤니케이션의 매개효과를 검토해보고자 하는 것이다. 분석결과를 요약하면 다음과 같다. 첫째, 팔로워십과 공동체의식은 커뮤니케이션에 긍정적인 영향을 미쳤으나 성실성은 인과관계가 없는 것으로 조사되었다. 둘째, 커뮤니케이션은 직무만족과 조직몰입에 긍정적인 영향을 주는 것으로 나타났다. 셋째, 교육참여자의 특성과 조직유효성과의 관계에서 커뮤니케이션이 매개하는 것이 입증되었다. 따라서 기업의 교육프로그램은 직무중심 교육에만 치중하지 말고 팔로워십 및 공동체의식을 함양할 수 있도록 종업원 개인의 가치관을 확립하고 조직구성원 간의 의사소통을 강화하는 역할을 할 수 있도록 설계되어야 한다.

A shielding effectiveness of mesh screen filter of plasma display panel (PDP) has been calculated in this paper. Since the screen filter is located near the radiation source, the near field wave impedance of the radiation source, i.e., the PDP electrodes, has been considered to calculate the shielding effectiveness. The near field shielding effectiveness of screen filter at 30${\sim}$300 MHz has been estimated to be more than 65${\sim}$80 dB. The measured shielding effectiveness of screen filter is 10${\sim}$50 dB at 30${\sim}$300 MHz[1]. The resulting discrepancy indicates that there are other EMI emission sources such as emission from PCB and cable besides the PDP electrodes.

IoT utilized network vitalization between objects are being rapidly established within current IT communication environment. Therefore the worth of smart mirrors is rising for it is a tool to allow online network between objects to be possible in human communication environment. For effective IoT generation's communication, this research intends to evaluate the smart mirror's value for practical uses based on the users' experiences. For the UX evaluation according to the locations where it will be used, Peter Morville's Honeycomb model and Jocob Nielsen's usage evaluation principles were referred to analyze effectiveness of 4 factors, utilization convenience, communication effectiveness, mass interest and space adequateness on households, public places and work places. Hence, we have were led to an objective result through statistical analysis method based on survey. As a result, we have confirmed the smart mirror's positive influence on the users' effective communication in all places. Especially in households, utilization convenience and space adequateness appeared to be high that confirmed sufficient users' need for the home-automation services. In public places, the communication effectiveness and space adequateness ranked high to confirm that the smart mirror utilization is adequate to provide location information. Also, in work places, the mass adequateness was high that we were able to confirm that supply of work place-specific service contents would bring meaningful results to the users. The smart mirrors are the adequate method to provide effective communication in IoT generation with high possibilities in further development.

The current study examined the difference of the college students' perceived stress and stress coping style according to the communication competence and communication amount & depth. Firstly, the differences of college students' perceived stress was shown according to their communication competence. Communication time (amount) and depth also affect their perceived stress. In detail, higher appropriateness and effectiveness were, the weaker the stress was. Secondly, the differences of college students' stress coping style was shown according to their communication competence, communication amount and depth. In detail, respondents who have high appropriateness showed the active stress coping style more. And respondents who have high effectiveness showed the active stress coping style more. Limitations and suggestions for future study were discussed thereafter.

융복합 시대에 기업의 문화경영 활동이 직원의 조직시민행동과 이직의도 등 조직 효과성에 미치는 영향에 대해 실증적으로 분석하였다. 특히, 조직 커뮤니케이션의 매개적 역할에 주목하여 기업의 문화경영이 조직 효과성의 행동적 차원에 미치는 영향을 구조적 모델을 통해 검증하여, 기업 문화경영의 가치와 중요성을 입증하였다. 분석결과 기업의 문화경영 활동은 조직 커뮤니케이션과 조직시민행동에 유의한 정적인 영향을 미치는 것으로 나타났다. 조직 커뮤니케이션은 기업 문화경영 활동과 조직효과성 간의 관계에서 매개효과를 갖는 것으로 나타났는데, 특히 기업의 문화경영 활동 자체가 이직의도를 감소시키는 것은 아니며, 문화경영 활동을 도입하는 과정에서 이를 뒷받침할 수 있는 조직 커뮤니케이션이 활성화될 때 이직률을 감소시킬 수 있다는 점을 의미한다.
