Computer-mediated communication(CMC) media has various forms through the technical improvements of computer and network, and CMCs communication methods are also comparative free rather than any other existing media without the limitation of time and space. Various CMC media were adopted by a lot of organizations for their communication tool. Thus, it is important to understand relationships of affecting factors to user's communication satisfaction for choosing the effective CMC media in their organizations. In this paper, we identify factors that may affect the communication satisfaction of users that has utilized the CMC media, and validate empirically the relationships between the identified factors in KOPTI. In the research model developed and described herein, perceived media richness was significantly associated with communication satisfaction and perceived usefulness was significantly associated with perceived media richness. Furthermore, perceived ease of use was significantly associated with perceived usefulness.

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.

With the increased use of computers in medical fields, we can consider introducing computer mediated communication into the area of patient care such as medical or health counseling and education. But little was known about what problems can be counseled, what is the main direction of counseling, and what difficulties are met during the computer mediated counseling. So I conducted this study. This is a fundamental study concerning the health counseling by the inter-net. In this study, medical counseling using a method of questioning -answering through a computer mediated communication system was carried out from June 1998 to May 1999. I analyzed the contents of questions and answers by the ICPC classification. The ICPC classification emerged as a standard for information categorization in Primary Health Care within a few years. One of the most prominent features of this classification is the inclusion of the complaints of the patients (symptoms & complaints) and the social problems (Chapter Z). Thus, and for the first time, the demand of patients may be assessed such as it is expressed in the reality. The ICPC list is now an international standard whose validity is not questioned any more. It is translated in more than twenty different languages. The data collected were analyzed by descriptive statistical method, c2 test by cross tabulations. Followings are the results of this study. 1. The 3,054 users composed of 64% of males and 36% of females. The highest number of users was showed in the age group of $25{\sim}29$ (39.4%). 2. During the one-year period, the average number of counseling per user was 2.5 cases and per day was 21.1 cases. 3. In classifying symptoms and complaints by 17 chapter, digestive(17.6%), general and unspecified (12.7%), skin(12.7%) and musculoskeletal system (9.6%) were most common questions. 4. The distribution of diagnosis by 17 chapter, general and unspecified (21.4%), digestive (15.3%), skin (11.9%) and mus- culoskeletal system (8.9%) were most common answers. 5. Many users wanted to know symptoms and complaints(3,609 cases), treatment principles (2,928 cases), prognosis and preventive methods for health problems which were previously diagnosed (284 cases).

Due to the development in computer mediated communication, there are many homepages on the web, which provide medical on health counseling and education. The internet is becoming increasingly important and essential in medicine. But little was known about what problems can be counseled and what difficulties are met during the computer mediated counseling. This study was performed to investigate the content and purpose of health counseling on the web. The data were collected from March 1st, 2002 to February 28th, 2003, from 199 questioners visited one rheumatic center homepage questionary/answering(Q/A) site. Most of the questioners consulted health problems of their own or their families. The 51.3% of them were diagnosed medically Rheumatoid arthritis was the most frequent disease and followed systemic lupus erythematosus, gout and ankylosing spondylitis. Most of the questioners needed to know treatment principles, diagnosing process, and information regarding the clinic. During the one-year period, the average number of users questioning was 29.4 cases and answering was 44.8 cases. Above findings suggest that computer mediated health counseling of rheumatic patients may be useful supplement of health education for them. Communication using internet has become popular, but this kind of approach needs a proper guideline. It is highly recommended that nurses be familiar with the e-health and e-medicine.

Purpose: In the digital age, visual cues in computer-mediated environments are becoming a very popular means of communication. Therefore, it is a very critical market for marketers to utilize for marketing communication and platform providers and manufacturers of mobile devices which create and distribute the visual cues While the prevalent research on visual cue consumption focuses on the positive side, the dark side of consuming visual cues has not been investigated. Therefore, in this research, the dark side of using visual cues, such as difficulties and problems in their application, will be investigated. Research design, data, and methodology: Due to the nature of this study, a netnography approach was adopted. Twitter which the users regularly utilise visual cues in their communications was a prime source for data of this research. Results: This research suggests that visual cue users experience anxiety about the subordination of expression and suffer from the myth of an ideal practice of expression. Conclusions: As the previous research emphasised the complementary role of visual cues, has failed to recognise the problems associated with the extensive and growing dependence on visual cues. This awareness demonstrates that we need to take a careful approach to visual cue usage.

Emojis and avatars are widely used in online communications, but their emotional conveyance lacks research. This study aims to contribute to the field of emotional expression in computer-mediated communication (CMC) by exploring the effectiveness of emotion recognition, the intensity of perceived emotions, and the perceived preferences for emojis and avatars as emotional expression tools. The following were used as stimuli: 12 photographs from the Yonsei-Face database, 12 Memojis that reflected the photographs, and 6 iOS emojis. The results of this study indicate that emojis outperformed other forms of emotional expression in terms of conveying emotions, intensity, and preference. Indeed, the study findings confirm that emojis remain the dominant form of emotional signals in CMC. In contrast, the study revealed that Memojis were inadequate as an expressive emotional cue. Participants did not perceive Memojis to effectively convey emotions compared with other forms of expression, such as emojis or real human faces. This suggests room for improvement in the design and implementation of Memojis to enhance their effectiveness in accurately conveying intended emotions. Addressing the limitations of Memojis and exploring ways to optimize their emotional expressiveness necessitate further research and development in avatar design.

With the rapid development of network and multimedia technologies, computer mediated communication has been realized and there has been a great potential to use and research on asynchronous voice communication systems. This paper reports a case study where 6 groups(3 for documentation work, 3 for software development) of 24 people who used voice mail when carrying out their projects. The purpose of this study is to obtain an overall understanding of usability of voice mail which is a typical example of asynchronous voice communication systems, under a particular situation where project works are performed. Through the study, we came to understand general purposes of usage of voice mail, patterns of using it revealed during the project process, different ways of using it according to different types of projects, and reasons why people are currently not likely to use voice mail. The results hopefully provide systems developers with a guideline to understand the nature of voice mail from users' perspectives.
