This study was carried out the group communication program which I had composed of using the Satir's communication family theory and skills. The purpose of this study was to investigate the effects on the dysfunctional communication self-esteem and depression, executed this program for the mothers group with caring the mental disorders. and then for the test of some hypotheses it was devided two groups ; the experimental group(n=20) and control group(n=25). In the control group they were learned two session family education program in the psychiatric clinics of Pusan National University Hospital and in the experimental group they had experienced during the 10 session by the group communication program. In the methods of the statistics on this datas, it was to statistics X²test for the comparison between the experimental group and control group with general characteristics. The effect of the Group Communication Program was to analyse ANCOVA between pre-post test on the disfunctional communication, self-esteem and depression in the control group and experimental group. The conclusions were derived from the results and test of hypothesis as followings ; 1) The results were tested the differentiation between the experimental and control group, and the pre-post test in the experimental group with dysfunctional communication self-esteem and depression. Some hypothesis were tested and supported as followings : It was supported that the level of dysfunctional communication of the experimental group would be lower than the control group (Hypothesis 1) It was supported that the level of self-esteem of the experimental group would be higher than the control group (Hypothesis 2). It was supported that the level of depression of the experimental group would be lower than the control group (Hypothesis 3). 2) The relation of the dysfunctional communication with the self-esteem was presented negative correlation and with the depression was not correlation. The relation of the self-esteem with the depression was presented significantly negative correlation. The relation of the sacrificuny pattern of dysfuntional communication with the self-esteem was presented negative correlation and with the depression positive correlation.

Purpose: The purposes of this study were to: (a) develop a comprehensive communication course combined with a group program for improving communication skills; and (b) examine the effects of the comprehensive communication course on interpersonal communication, relationship change, self-esteem, and depression in nursing students. Method: The experimental group consisted of 82 nursing students, and the control group, 108 nursing students. Both groups each took communication courses from March to June, 2002 and 2003. A group program for improving communication skills was conducted for each 8 subgroups of the experimental group for 90 minutes once a week during the 6 weeks, while the existing communication lecture was conducted for the control group. Both groups were post-tested after the intervention for verifying the difference of variables between the two groups, and the experimental group was also pre-tested for verifying the difference between before and after the treatment. Result & Conclusion: Interpersonal communication score of the post-test in the experimental group was significantly higher than in the control group and the depression score of the post-test in the experimental group was significantly lower than in the control group. Interpersonal communication, relationship change and self-esteem scores were significantly increased and the depression score was significantly decreased in experimental group after the treatment. In conclusion, the comprehensive communication course that was developed in this study had positive effects on communication skills in nursing students.

Group communications are becoming popular in Internet applications such as video conferences, on-line chatting programs, games, and gambling. Secure and efficient group communication is needed for message integration, confidentiality, and system usability. However, the conventional group key agreement protocols are too much focused on minimizing the computational overhead by concentrating on generating the common group key efficiently for secure communication. As a result, the common group key is generated efficiently but a failure in authentication allows adversaries to obtain valuable information during the group communication. After achieving the secure group communication, the secure group communication should generate the group key efficiently and distribute it to group members securely, so the balance of security and system usage must be considered at the same time. Therefore, this research proposes the software architecture model of a secure and efficient group communication that will be imbedded into networking applications.

Purpose - The objective of this study is to identify the effects of the communication cues and anonymity on group polarization in mobile communication settings, both in terms of route and extent. Research design, data and methodology - Laboratory experiments were conducted to achieve the above research objective; the effect of communication cues on group polarization with social presence as mediation and the direct effect of anonymity, social presence, and perceived cohesion were analyzed. The experiments were conducted by the participation of 240 people, who were divided into 48 groups of 5 people. Results - According to the results, the difference in intergroup polarization due to communication cues and anonymity was insignificant. From this analysis, the structural equation model, communication cues and anonymity did not affect group polarization through social presence. Moreover, anonymity did not affect group polarization through perceived cohesion; however, anonymity directly affected group polarization. Conclusions - This research can help to explain the discussions and the related decision-making actions on internet forums, which have recently come to the rise as well as provide foundational basis in newly establishing policies for the forums.

Objectives: Interpersonal stress is a major cause and aggravating factor of Hwabyung. The purpose of this study was to compare communication type and stress coping style between the Hwabyung patients group and non-Hwabyung patients group. Methods: The total number of study participants was 101. Based on the Hwabyung symptom scale, the study participants were divided into Hwabyung patients group (30 patients) and non-Hwabyung patients group (43 patients; control group), and the others were excluded from the study . All included patients were administered the Virginia Satir’s communication type questionnaire and stress coping scale based on Folkman & Lazarus’s theory. The independent t-test was used to determine the statistical significance between the features of communication types and stress coping styles in each group. In addition, Spearman correlation analysis was used to identify the relationship between communication types and stress coping styles. Results and Conclusions: 1. Communication types differed significantly between the Hwabyung patients group and non-Hwabyung patients group. 2. Hwabyung patients scored significantly higher in each dysfunctional communication type than functional communication type. Scores of placating stance and super-reasonable stance, which were subtypes of dysfunctional communication type, were high in the Hwabyung patients group. The non-Hwabyung patients group scored the highest in Congruent stance, classified as functional communication type. 3. Stress coping style was not significantly different between the two groups.

This study explored the influence of two types of conflict(task and relationship conflict) on group creativity and tested this model with a sample of 58 teams. Relationship conflict negatively influenced group creativity but, task conflict did not show the effects on group creativity. Specifically we found the moderating effects of supportive leadership and communication. Supportive leadership style moderated positively both task conflict and relationship conflict on group creativity. But controlling leadership styled moderated negatively relationship conflict and group creativity. Finally the relationship between task conflict and group creativity was moderated by communication. Overall, we suggest conflict is one of the important group process to boost group creativity and supportive leadership and communication are the important moderators to manage conflict successfully and effectively.

Group communication is one of key components supporting object replication. CORBA provides little support for fault tolerance and high availability that can be supported by means of object replication. The existing approaches do not allow transparent plug-in of group communication protocols into CORBA with which CORBA application programmers are able to directly exploit group communication protocols. They either require modification of CORBA or OS, or provide no room for incorporating group communication transport protocols into CORBA. In this paper, we propose a generic group communication framework that allows transparent plug-in of various group communication protocols with no modification of standard CORBA. For this, we extend the Open Communications Interface(OCI) to support interoperability, reusability of existing group communication, and independency on ORB and OS. The proposed approach can also be applied to various group communication protocols.

This study identifies communication patterns of groups using synchronous text communication medium for their group decision-making, and examines how these patterns are associated with creative solutions to problems. Our research suggests that certain communication behavior of groups, when appropriately organized, can be of help in enhancing creative production of outcomes. A qualitative study was conducted on communication patterns based on an analysis of text-based electronic conversation protocols. Specifically this research tried to overcome existing studies on electronic groups by focusing on interactive process of communication among participants. The major study conclusion; are: (1) The production of creative outcome may depend on the process or sequence of discussion among group members with synchronous text communication medium. That is, proper interactive responses and appropriate control of the discussion process are essential to obtain a high level of performance. (2) It is importantto make discuss rules based on meta-cognitive and interactive protocols in the early stage. Explicit rules relating to internal group processes as well as communication medium use are even more important to groups with electronic communication medium than face-to-face groups.

Purpose: The present study was to examine the effects of a communication training program on nursing students' interpersonal communication and relationships. Methods: This study was quasi-experimental research using a non-equivalent pre-post design. The subjects were 40 sophomore nursing students who were divided into an experimental group of 20 members and a control group of 20 members. The communication training program consisted of 8 sessions of small group training and each session lasted 120 minutes. A pretest, posttest and follow-up test (6 months after the program was terminated) were conducted to measure Inter-personal Communication Inventory and Relationships Scale. Data was analyzed by $X^2$-test, independent t-test, paired t-test and Friedman test with SPSS. Results: The communication training program was very effective in enhancing the nursing students' communication and interpersonal abilities. Nursing students' communication ability in the experimental group, however, decreases after 6 months while there is no change in the control group. Nursing students' interpersonal relationships in the experimental group was maintained at the follow-up test. Conclusions: This study supports that a communication training program has a positive effect on improving the nursing students' communication skill and interpersonal relationships.
