The purpose of this study is to identify the effects of the supportive nursing care for arthritis patients enrolled in a rheumatoid clinic. To achieve this purpose, this study adopted a quasi-experimental, pre- and post-test research design, categorized subjects into experimental and control groups. Outpatient clinic nurse alloted the subjects by experimental and control groups and nurse researcher meets the experimental subject with in-depth, direct personal interview and advices via telephone for 8 weeks. During this pre and after the treatment period, the level of pain, uncertainty, self-efficacy, family support, and perception for health were measured. Analyses for the measured results for pre- and post-test showed that the supportive program conducted during this study decreased the level of uncertainty and increased the perception of family support in experimental group. So, the supportive healing interpersonal communication service proved to be effective and this result justifies the argument that the role of the nursing professionals at out-patient clinic should be extended for the more qualified care for the patient.

Our world has become an increasingly complex place in which, as individuals, We are very dependent on other people and upon organizations. An event in some distant part of the globe can rapidly and significantly affect the quality of life in our home country. This increasing interdependence, on both a national and international scale, has led us to create systems which can respond immediately to these systems are operating all around us in military, civil, commercial and industrial fields. The electronic computre is at the heart of many such systems, but the role of telecommunications is no less important. As we proceed through the 1980s, there will be a further convergence between the technologies of computing and telecommunications. We cannot doubt that the economic and social impact of these concepts will be very significant. Already. advanced systems of communication are affecting both the layman and the technician. Complex functions are being performed by people using advanced terminals which are intended to be as easy to use as the conventional telephone.

With the rapid development of communication technology and widespread uses of internet service, utilization of internet-based medical information systems which transmitts moving pictures of medical objects is becoming a common practice. The internet-based medical information service prvovides richer information than conventional services such as touch-tone telephone, personal computers e-mails, or pagers, because "a picture is worth a thousand words". However, the systems passively transmits moving pictures of the medical objects to the users, and thus the system cannot intelligently adjust itself to provide better service. As the tradeoff exists between transmission speed and quality of the image, there is a need that moving pictures be analyzed to adjust the trnasmission speed and image quality. When very little difference between consecutive images are detected, the system can automatically increase the size of the image files, thus enhancing the quality of image. In contrast, the system should increase the number of images to send more pictorial information by sacrificing the quality of each individual image, when a significant difference is detected. In this paper an adaptive filtering technique is introduced which adjusts the quality of image and transmission speed according to a clinical situation in hospital.

In this paper it Is to suggest that beyond the Previous communication concept of exchange, transmission mounting. and terminal , the call control system function should be added to the call control exchange server, to make an external telephone call available through the internet by connecting the interior line and the Internet. The function evaluation of call control system is found to become stable when the callers are 10 rather than 20 above, as a result of the more than ten times repeated concurrent calls. Furthermore, the evaluation shows that the program responds Quickly within a second, even when there are more than 100 callers as well as secures a stable system operation and mutual inter-feasibility due to a fast connectivity and a superb function.

Voice dialing system can recognize the speaker's command and dial the destinate phone number automatically. Such a system is useful for wireless handsets and portable communication devices. As a personal voice dialing system, all the commands are used to train the HMM for speech recognition based on owner-selected phrases. Its implementation requires much less memory space and computation resource compared to a speaker-independent system. Since only two or three training utterances per command are used in this system, it is difficult to estimate exact state duration distribution to improve the recognition performance. Therefore a post-processor is presented to improve the performance. Experiments which use the database collected through the telephone line showed that the proposed post-processor improves the recognition system performance.

In this study commuter marriage was defined as a family in which working husband and wife, who have professional job having family orientation and job orientation, come and go lived separately for more than days a week for working in different region. This study examined the determinants of living separately the merits and demerits of commuter marriage, relation with family, family finance and household work for twelve case wives fitted for above definition, and the findings are as the following. The main cause of commuter marriage was wife's work place. The merits of commuter marriage were that wives can devote to their own increased time and that they had fresh feeling to their husbands. The demerit were mental burden to mother-in-laws and their mothers who take charge of home management and the high cost of living for double housekeeping. In the area of relation with family, they and their husbands call above one time per day for communication although they live separately for three or four days, do not insist on norms of living together, and overcome difficulties of commuter marriage well. In the area of family six couples used allowances method. They have high living cost like traffic expenses, telephone charges, and housing expenses because of double living. In the area of household work, they mainly manage family life with the help of household helpers like mother-in-laws or their own mothers.

The purpose of this study is to identify the effects of the supportive program for arthritis patients. who are attending a rheumatoid arthritis clinic. To achieve this purpose. this study adopted a quasi-experimental. pre- and post-test research design. comparing experimental group with control one. Supportive program was composed of in-depth. 3 times of direct interview and 2 times of advice using telephone for 8 weeks. The object of these interviews and phone was focused on the improvement of patients' preception for health. During this period. the level of pain, hemato-immunologic indices(ESR, CRP). self-efficacy, depression. and perception for health were measured in both grooups. Data were analysed by $x^2-test$, t-test. repeated measures ANOVA and Pearson's correlations. The results were as follows : 1. There were no significant differences in physiological data. 2. The feeling of self-efficacy was significantly increased in experimental group(P=.012), 3. There was no significant differences in depression. 4. The perception for health status was significantly increased in experimental group(P=.002). Thus, the supportive program. which is focused on the close interpersonal communication. proved to be effective. This result justifies the following suggestion that the role of the nursing professionals in out-patient clinic should be extended for more qualified care for the patients.

The purpose of this study is to describe the health care status of Korean Immigrants in New Zealand. The sample consisted of 155 Koreans who were randomly selected from the Korean Immigrants telephone book in Auckland, N.Z. They had health problems that required health management both physically (50.3%) and psychologically(70.3%). During the previous year, the average rate of medical contact with a general practitioner was 1$\pm$1.29 times. Korean immigrants who had health problems first attempted to resolve the problem through self medication rather than utilize health care services. They would only visit a general practitioner if they had severe subjective symptoms or no relief from self medication. Even if they think they need to visit the health care service, 41.9% of the subjects did not go back for follow-up care. Generally, the person who demonstrated positive health care behaviors was male, a college level graduate or higher, lived in N.Z. longer than 2 years, had a high score on health status by self assessment, and he placed few demands on health care services. Barriers to a healthy lifestyle are communication difficulties in expressing subjective symptoms, understanding the physician's treatment and medication plans, difficulty in accessing the appointment system and the high cost of service.

Voice over IP is a telephone service which sends and receives the voices through the Internet. Because the infrastructure of wireless and mobile communication networks such as 3G, Wi-Fi and WiMAX has expanded, the study about Mobile VoIP, which provides the voice service from wireless network, has been actively in progress. Since Rei 6 HSPA in 3GPP and Rev A lxEVDO in 3GPP2, VoIP through the data channel is more efficient than circuit switch. It is predicted that VoIP over 4G will be more effective and 4G mobile VoIP business will be vitalized in the future. In addition, there are businesses which offer VoWLAN by using software such as Skype and Fring. They provide services which cheapen the price of international calls and long distance calls. This paper will present the Korean and other countries' mobile VoIP trends, its classification along the network connection, the study on techniques, and conditions of mobile VoIP. It also will be described a view of terminal convergence and service convergence.
