  • Softswitch is the core BcN equipment which voice and multimedia switching based on the IP Technologies. It is designed to replace the Class 5(local Exchange) and Class 4(Toll Exchange) switch based on the circuit wired and wireless switching network technologies. Softswitch gets its name because typically it is a software based solution implemented on general purpose computers/servers. While the traditional PSTN switches are rely on dedicated facilities for T and S inter-connection and are designed primarily for voice communications. Packet based Softswitch is divided the control of call and bearer, very different from Public telephone network. Sometimes Call Agent or Media Gateway Controller, a key component in the VoIP solution, is also called Softswitch. This paper will suggest the software architecture of softswitch for performance in call processing part, also suggest the session management model to cover call setup latency.

  • A descriptive study was conducted to describe the content of nursing interventions and incoming telephone calls from the parents whose child was discharged to home or who has planned immunization during the period from March 15, 1995 to November 30, 1995. Detailed notes on 145 telephone calls and 243 nursing interventions were recorded by head nurses on pediatiric nursing units were entered to data collection and content analysis. The results of the study are as follows : 1. Six analysis categories for the records on incoming telephone calls were identified judgement-dependence, dependent -coping, self-initiated coping, support, adjustment and intermediation need. 2. Five analytic categories for the records on telephone interventions were identified : guidance, mediation, facilitating self -care abilities, support, instrumental use. 3. Problems related to physical signs and symptoms, medication, immunization, and vital signs were most often cited as concerns by parents and caregivers. 4. Instruction, suggestion, provision knowledge and information, reassurance related to physical problems, medication, immunization and clinic visits were most often used as an nursing interventions by head nurses on pediatric nursing units. In spite of the fact that the telephone calls were initiated by the parents, dependency of parents during the telephone calls was remarkable. The dependency of parents on judgement and decision making of the pediatric nurses should be understood in terms of the psychosocial content as well as cultural characteristics. Therefore, it is suppested that telephone interventions focus on facilitating the self-care ability of the parents whose children have chronic conditions. The results of this study will be useful as an essential reference in providing effective for children and their families after discharged from the hospital. The results can also be used as reliable data for extended pediatric nursing service in the health care delivery system as well as for the development of telephone intervention service program in responding to the current health care environment.

  • This article describes several clinical usefullness of the telephone in psychotherapy with adolescents through case analysis by Tolchin, and discussed various management problems and some practical guidelines for therapists planning to utilize telephone psychotherapy with adolescents through literature analysis. In general, most adolescent patients in regular treatment benefit from knowing that the therapist can be reached by phone and that their call will be returned that same day. The therapist's telephone availability helps the young patient to develope a positive working alliance. Telephone psychotherapy had it's first widespread application in crisis intervention and suicide prevention. It's current uses also include enhancement of self-control in cases of self-destructive adolescents, and management of anxious, depressive, or anorexic adolescents. In addition, such widely divergent modalities of treatment as follow up of patients discharged from a psychiatric hospital, alcoholic rehabilitation programs, drug hotlines, sex counselling group therapy for visually impaired elderly, control of separation anxiety in girls, resolution of fear on the mental disorders, and helpful modality to continue psychotherapy without geographic barrier during longer periods of separation with therapist are currently available via telephone. But telephone psychotherapy is generally not suitable for more self-defensive and introverted cases, more dependent chronic callers, silent cases, test callers. the cases of telephone scatologias, the cases of intellectualized discussion, of more dependent cases calling phone in order to get attention from therapist. Telephone psychotherapy for adolescents serves as an important and useful method in the therapeutic armamentarium for this most challenging and rewarding population.

  • This study aims to analyze the usefulness of the survey procedures developed for telephone surveys using a random sampling method. We conducted a telephone survey of residents in a local area from October 26 to November18,2009. We applied random sampling procedures with five call-backs. Particular attention was given to the conversion of refusals. Out of 2,454 phone numbers, we succeeded in getting responses from 637 numbers. The absence of residents was the primary cause of non-response. We received responses from 45.7% of those with whom we successfully made contact. One finding of this study is that, contrary to our initial expectations, call-backs do not significantly increase the percentage of responses from young people. Also we cannot find any significant differences in responses to various questions between the responses received from the first round of calls and later responses. However, these results are not conclusive; another survey may produce different results. Therefore, further research is needed.

  • A system to assist call routing task for telephone operators at the Directorate General of Telecommunications (DGT) in Taiwan is reported in this paper. The system was developed based on DGT organization profile with description of its six divisions instead of a corpus of recorded and transcribed call-routing dialogs. An acoustic module and an information retrieval module were built specifically for this task. The construction of IR module was based on term extraction and thesaurus discovery processes. By integrating acoustic and IR module, the system achieves satisfactory performance and provides a promising approach to call routing. Simulation results indicated that the proposed algorithm outperforms standard classification methods. A working system based on the proposed approach has been implemented and experimental results are presented.

  • The development of information and communication technology affects people's life in social, cultural, and economic aspects. When this happens in public sector, it gives way more benefits than in private sector because of its high accessibility by public. Among the technological public services in Korea, call center service which provides administrative services by telephone and internet had been spotlighted as a new type of communication between people in demand and public service provider. Public call center service is expected to be continuously diffused in years due to its accessibility and convenience for public users. This study analyzes diffusion pattern of public call center service in Korea using Bass model and tries to suggest appropriate diffusion strategies. For practical cases, three most popular public call centers in Korea are analyzed in light of diffusion pattern and operating strategies. Our analyses identify that public call centers in Korea are facing continuous diffusion in two years and there exist certain strategies to efficiently expedite the diffusion.
