This is an experimental study which is designed to identify the joint relationship between communication density and centrality as independent factors to team performance, discovering how they would jointly affect work team performance. Specially different from existing studies, separating team performance into team efficiency and team effectiveness, we identified differential influences to the two independent factors. Findings suggest a competing relationship between communication density and centrality. A framework was proposed to help managers understand the joint effect of density and centrality on performance. Work team has high communication density and low centrality is "Innovating", which is likely to have a great extent of ideas, knowledge and information sharing, and reach high effectiveness. Team with high centrality and low density is characterized as "centralized". Such communication structure may reduce diversity of perspectives and accelerate team decision making. When both density and centrality are low, the team is "Autonomous". To increase external validity, other factors such as leadership, organizational climate influencing on team performance should be reflected in the future research.

1. Introduction The new computing era started with the various computer technologies and services having been used in communication and automation area since 1980's. We call that era information technology(IT) era. In such era, especially communication plays very important roles in every aspect. So Schoderbek named that era the ege of c2. Therefore, communition became widely used in organizations. Now the majority of organizations have computer-aided communication capabilities that facilitate access to people and information, both within and outside organization. So one objective of this study is to assess the effects of these changes in data communication on decision making. Decision making is the essence of management and is too important to organizational success. This dissertation has three basic objectives: 1)to clarify the concept of data communication, who influences on decision making, and the concept of decision types, managerial and operational, may be affected differently by data communication 2)to investigate whether the effects of data communication upon decision making may be organizational variables. 3)to verify that business and decision types may affect different impact on decision making.2. Hypotheses Four attributes are selected to make hypotheses from the information attributes presented by famous scholars. They are as follows. ①effectiveness ②routinization ③communication easiness ④timeliness Hypotheses are developed according to these attributes, which are chosen from the literature study and theory H1 : Data communication is positively related to the effectiveness of DM H2 : Data communication is positively related to the routinization of DM H3 : Data communication is positively related to the communication easiness of DM H4 : Data communication is positively related to the timeliness of information for DM3. Methodology After pilot study, data are collected from the decision makers in 200 companies located at Seoul and the metropolitan area. A random sample of 174 employees sent back their questionnaires(response rate of 87%). Among them, 151 questionnaires was useful to the analysis of this study(useful rate of 75.5%).4. Conclusion and Discussion Among four proposed hypotheses, all hypotheses are fully supported. They are as follows. 1)effectiveness 2)routinization 3)communication easiness 4)timeliness. So, first objective of this study is proved. Namely, to clarify that the effects of data communication upon DM is fully supported. But they are different from the decision types. Second one is not apparently verfied. i.e. the effect of data communication on the decision variables is not moderated by organizational variables. Third is inspected. The effects of data communication differs from the industry and decision types evidently. This study has many limitations to generalize the statistical results. Since the definition of data communication has broad meanings in reality. So allare not contained in this research. Another restrict in this study is like this. Decision types are usually divided into three types-operational, managerial, strategic DM. But in this study, strategic DM is left out.

Communication errors have severe consequences clinical quality and disputes in medical organizations. Thus, clinical communication has become a major practice recently, since clinical and managerial effectiveness can also be enhanced by improving the quality of the physician, medical staff, and laboratories interactions. Both medium and large-sized hospitals are increasingly adopting the philosophy to shorten clinical service time while enhancing higher medical service quality and lower healthcare service costs. From this motivation, this paper studies on the clinical collaborative communication concept and investigates approaches to the philosophy for implementation. The system has been theorized to improve communication and enhancing medical outcome qualities. In addition, to validate the system, the author analyzes the efficiency and effectiveness in S hospital, using statistical survey works.

The purpose of this study was to examine how the interaction between organizational culture and organizational communication factors on the effectiveness of a set of organizations has an effect on organizational effectiveness. For the empirical analysis of this study, we conducted a questionnaire survey on the subjects who participated in the core job training course of SMEs. To test the hypothesis of this study, we analyzed the moderating effects of organizational communication on the relationship between organizational culture type and organizational effectiveness by statistical analysis, correlation analysis, regression analysis, multiple regression analysis, and control effect analysis through statistical program SPSS 20.0. The results of the empirical analysis show that organizational culture type positively influences organizational commitment and job satisfaction, but organizational culture has a positive effect on organizational culture. It exhibited a positive moderating effect. Therefore, this study reviewed the theoretical validity of existing studies by analyzing the moderating effects of organizational communication in the relationship between organizational culture type and organizational effectiveness. On the other hand, the empirical analysis of the interaction effects of variables can be interpreted as the pursuit of integration between prior researches that were performed individually.

The EMI shielding effectiveness of shielding layers thickness was analyzed when the low conductivity shielding layers was placed in the near field of the noise source. A spiral antenna with broadband characteristics was used as the noise source, and graphite was selected as the low conductivity shielding material. Two spiral antennas were constructed to analyze the transmission coefficient between two antennas, and the distances between the transmitting and receiving antennas were 5 cm and 10 cm. The thickness of the shielding layers was changed from 1 um to 200 um. The frequency was changed from 100 MHz to 6 GHz to obtain a maximum SE(Shielding Effectiveness) of 70 dB. In this simulation, electronic shielding was used due to the nature of graphite, which is a shielding film material. Based on these results, we will study how to improve the shielding performance by implementing magnetic shielding in the future.

Objectives: The study aimed to investigate the effect of communication competence on the organizational effectiveness in dental hygienists. Methods: A self-reported questionnaire was completed by 248 dental hygienists in Seoul, Incheon, and Gyeonggido from November 1 to 30, 2014. The questionnaire consisted of general characteristics of the subjects(4 items), job characteristics(10 items), communication competence(49 items), organizational commitment(15 items), job satisfaction(16 items), and turnover intention(5 items). The instrument for communication competence and organizational commitment was done by Likert 5 points scale. Data were analyzed by t test, one way ANOVA, stepwise multiple regression test, and post-hoc Scheffe test using SPSS 18.0 program Results: The average of communication competence was 3.49(${\pm}0.28$). Of the sub-factors of communication competence, interpretational competence had the highest score of 3.65(${\pm}0.33$) followed by self-presentation 3.50(${\pm}0.49$), message conversion 3.50(${\pm}0.47$), role performance 3.44(${\pm}0.37$), and goal setting competence 3.28(${\pm}0.60$). There were significant effects in the organizational commitment including workplace(dental clinic=1, ${\beta}$=-0.254), weekly average working hours($${\leq_-}40$$ hours=1, ${\beta}$=0.182), role performance(${\beta}$=0.163), self-presentation(${\beta}$=0.144), goal setting competence(${\beta}$=0.130), and position(head=1, ${\beta}$=0.137). There were significants effects in the job satisfaction including position(head=1, ${\beta}$=0.217), weekly average working hours($${\leq_-}40$$ hours=1, ${\beta}$=0.204), education level(graduate school=1, ${\beta}$=0.184), job career(3~6 years=1, ${\beta}$=-0.181), goal setting competence(${\beta}$=0.194), and interpretational competence(${\beta}$=0.124). Conclusions: The communication competence of the dental hygienists showed a partial effect on the organizational effectiveness. In order to improve the organizational commitment and job satisfaction and the turnover intention, a variety of efforts must be taken and focused on goal setting competence, role performance, self-presentation, and interpretational competence.
