The main purpose of this study is to assess the relationship between communication satisfaction and group creativity. To achieve this purpose, this study has two objectives. First, I will identify the relationship between the satisfaction of communication and idea creation. Second, the relationship between communication satisfaction and problem solving activity will be statistically tested. The major findings of the study can be summarized as follows: First, Statistically significant positive relations were found between the communication satisfaction and idea creation. Especially, sub-construct for supervisor communication$({\beta}=0.14,\;p<.05)$, quality of media$({\beta}=0.13,\;p<.05)$, individual feedback$({\beta}=0.36,\;p<.001)$, organizational prospect$({\beta}0.31,\;p<.001)$ showed the statistically significant positive(+) relationship with construct in idea creation. Second, the measurement of communication satisfaction had showed statistically significant relationship with the problem solving activity. Especially, communication with supervisor$({\beta}=0.21,\;p<.05)$, quality of media$({\beta}=0.21,\;p<.001)$, organizational prospects$({\beta}=0.22,\;p<.001)$, and communication with subordinate$({\beta}=0.37,\;p<.001)$ showed the significant positive(+) relationship with problem solving activity construct. These consequences suggest that communication satisfaction of employee is effective in the improving the group creativity in organization. In the conclusion, this study present the satisfaction factor of employee communication as a incremental factor of group creativity.

The objective of this study is to examine the media richness theory and the social information processing model by analyzing the effect of media experience on media perception and communication process. To accomplish this objective, a laboratory experiment was conducted. The independent variable was text medium experience and a face-to-face medium was added as a control group. The dependent variables were medium perception and communication process. Medium perception includes perceived richness, medium feeling, task satisfaction, and communication satisfaction. Communication processes were also analyzed to compare each treatment group. The results can be summarized into two facts. First, face-to-face group showed higher perceived richness than text medium group. And experienced text medium group perceived their text medium richer than inexperienced text medium group. Second, experienced text medium groups showed more interactions between subjects than inexperienced text medium group. Experienced text medium group also showed more agreements and meta-communication which could be found in face-to-face group. The result of this study supported media richness theory by finding that face-to-face medium was perceived richer than text medium, And the results also proved social information processing model by comparing experienced text medium group and inexperienced text medium group. The text medium, although thought to be the leanest one, could be perceived richer if users had lots of experience on it.

Purpose - This study aims to identify the effects of communication cues, anonymity, and social presence on group polarization in computer-mediated communication (CMC) settings. Extant literature has introduced some theoretical backgrounds of social presence and SIDE (Social Identity model of Deindividuation Effects) to explain the effects of communication cues and anonymity. The concept of social presence emphasized the mediating role on communication cues and anonymity. However, most literature did not measure social presence and compare group polarization of all condition groups. This does not sufficiently explain the result of group polarization. Research design, data, and methodology - We believe that the direct impact of anonymity on group polarization can provide a more admissible and clearer explanation for the results. In addition, this study categorizes anonymity into two levels, as anonymity of group and anonymity of self. To justify the anonymity view, a laboratory experiment was conducted. The experiment was conducted in communication cues settings (visual cue; without visual cue) and anonymity settings (identified; anonymous). Each of the four settings has 10 groups consisting of five subjects each (total 200 subjects). The subjects are undergraduates from a large university, majoring in business. All experimental procedures and calculations of choice shift and preference change follow the literature. Results - First, the removal of visual cues does not produce a significant impact on group polarization, which cannot be explained by the social presence view. Second, the anonymous condition does not significantly affect group polarization, which also cannot be explained by the social presence view. However, the anonymous condition directly affects group polarization. Specifically, anonymity of self has a stronger effect on group polarization than anonymity of group. The result explains about the leading factor affecting group polarization. This study examines another view of how computer-mediated communication may be associated with group polarization. The process and outcome data from the experiment reveal that group polarization is not affected by level of social presence, but by level of anonymity. Group discussions conducted with visual cue CMC setting and identified CMC setting result in weaker group polarization. Conversely, group discussions conducted without visual cue CMC setting and anonymous CMC setting lead to stronger group polarization. The results of the study have the following implications. First, they provide clues for business organizations to design the most appropriate media conditions and preemptive social conditions to implement when making group decisions through CMC, to maximize achievements, generate amicable agreements, or actively share information. Second, this study can be useful in analyzing different adverse effects generated through Internet use. Conclusions - This research can help explain discussions and decision-making actions on Internet forums, which have recently increased, as well as providing a foundational basis in newly establishing policies for the forums. Finally, it should be noted that many other factors such as group size, topics, and group history may affect group polarization. These should be examined in future studies.

Background: Communication training in nursing college students is an integral part of the development of their competency in dealing with patients. However, the traditional lecture style of training delivery may not be desirably effective. Purpose: This study investigated the effects of a communication training program utilizing a small group dynamic on the communication competency and human relationships in nursing college students. Methods: One hundred twenty six freshmen in a university in Seoul participated in this study. The instruments of communication competency (Primary Communication Inventory) and human relationships (Relationship Change Scale) were used at the beginning and conclusion of the training period. Eighty-three students from two nursing classes were assigned to the experimental groups and 43 students from other classes were assigned to the control groups. Each of the 11 small groups was composed of 7 or 8 students. The weekly program that ran during the 2007 fall semester from October 1st to December 11th consisted of effective communication strategies including therapeutic communication skills, Johari's window, empathy, active listening, and transactional analysis. Results: The experimental group of students reported significantly greater improvement in communication competencies, specific nonverbal competencies, and human relationships compared with the control group. Specifically, the experimental students demonstrated greater improvement in nonverbal communication competencies and satisfaction, communication, and awareness of human relationships. Conclusions: Small group based communication training can be an effective alternative method of communication education for college nursing students.

주파수공용통신(TRS: Trunked Radio Service)이란 무선통신을 하는 사람이 특정한 주파수를 이용하던 종래의 무선통신방식과는 달리 중계소에 할당된 소수의 주파수를 다수의 이용자가 공동으로 사용하는 방식을 말한다. TRS 시스템의 가장 큰 특징은 일대 다수의 그룹 및 지령 통신방식이다. TRS 시스템의 구성은 여러 개의 그룹으로 구성되며, 각 그룹은 업무내용에 관련된 유사한 목적을 가진 사용자들의 단말기로 구성된다. 위와 같은 여러 목적에 따라 다양한 형태의 연결이나 그룹 통신이 이뤄질 경우, 여러 가지 형태의 공격에 노출될 수 있으며, 대규모 통신을 위한 키 분배 혹은 설정에 많은 문제점을 가질 수 있다. 본고에서는 TRS 상에서 안전한.통신을 수행하는데 있어 필수 요소인 그룹 키 분배방식을 고찰하며, 통신 횟수를 줄이면서도 참여자 인증을 수행할 수 있는 효율적인 그룹 키 분배 방식을 제안하였다.

Purpose: This study was conducted to examine the effects of a communication empowerment program based on situated learning theory for nursing students. Methods: A non-equivalent control group pretest-posttest design was used. The study participants were 61 nursing students (31 in the experimental group and 30 in the control group) from G city. Data were collected from November 3, 2015 to December 10, 2015. The experimental group received eight sessions of the program, which were scheduled twice a week, with each session lasting two hours. The data were analyzed using chi-square test, Fisher's exact test, and an independent t-test using SPSS/WIN 20.0. Results: There were significant increases in self-efficacy for communication (t=2.62, p=.011), emotional intelligence (t=2.66, p=.010), and interpersonal communication competence (t=2.87, p=.006) in the experimental group compared to the control group. Conclusion: Based on the findings, our study suggests a need to include content from communication curricula or clinical communication training programs for improving undergraduate nursing students' communication skills in practice settings.
