우리나라의 거의 모든 전화조사는 전화번호부를 표본추출의 틀로 쓰고 있는데 전화번호부의 등재율이 낮아 포함오류(coverage error)가 심각한 실정이다. 전화번호부 기반 전화조사에 대한 대안으로 미국 등에서는 임의번호걸기(RDD: Random Digital Dialing) 전화조사를 하지만 우리나라에서는 아직 하지 않고 있다. 본 연구의 목표는 다음 두 가지이다. 첫째, 우리나라 전화번호 체계에 맞는 RDD 전화조사 방법을 제안한다. 둘째, 실제 RDD 전화조사를 시행하여 전화번호부 등재 응답자와 비등재 응답자의 사회 인구적 특성과 사회 심리적 성향을 비교해 본다. 조사결과를 요약하면 다음과 같다, 1) 전화번호부의 모집단 포함율은 60% 이하로 추정되었다. 2) 비등재 가구의 소득이 등재 가구의 소득에 비해 다소 큰 것으로 나타났다. 3) 비등재 가구의 가구원 수가 등재 가구의 가구원 수에 비해 다소 많았다. 4) 비등재 번호 응답자들이 등재 번호 응답자들에 비해 개인정보에 대한 침해우려 수준이 다소 높았다. 5) 이념성향에서 비등재 번호 응답자들이 등재 번호 응답자들에 비해 진보적인 경향이 있었다. 이와 같은 사실로부터 전화번호부에 기초한 표본추출이 사회경제적 측면에서 편향된 결과를 산출해 내고 있음을 알 수 있다.

Purpose: The purpose of this study was to determine the effects of self-care program using Short message service (SMS), e-mail, or telephone call on self-care compliance and nutritional status in maintenance of hemodialysis patient. Methods: Nonequivalent pretest-posttest control experimental design was used. Ninety-six patients were allocated to control (n=24), SMS (n=24), e-mail (n=24), or telephone (n=24) group from four hospitals. Experimental groups received self-care program about hemodialysis diet, drug administration, exercise, and fistula care by SMS, e-mail, or telephone call respectively at 3 times a week for 4 weeks. Results: Subjective self-care compliance, and objective self-care compliance including interdialytic weight of SMS and telephone groups were significantly increased than those of control groups. However, nutritional status of SMS and e-mail groups were significantly improved than those of control groups in albumin and protein level. Conclusion: Self-care program using SMS and telephone call were effective on promoting self-care compliance, while SMS and e-mail were effective on improving nutritional status. The pop-up remaining effect and easy accessible effect of SMS message in busy daily life was considered as an alarm to control fluid and diet.

Purpose: The main purpose of this study was to examine the effectiveness of a standardized telephone monitoring intervention in addressing the symptom experience and improving self-management ability in patients with heart failure. Methods: A non-equivalent control group pre-post test design was used. There were 17 patients in the experimental group, and 16 in the control group. According to the protocol, patients in the experimental group received 15 to 30 minute-telephone monitoring four times, once a week for 4 weeks. Data were analyzed by ${\chi}^2$-test, Mann-Whitney U test. Results: 1) The experimental group showed a significant increase in compliance with self-management compared to the control group. 2) There was a significant decrease in degree for 3 symptoms(DOE, PND, & continuing fatigue) in the experimental group, after telephone monitoring. However, the experimental group did not show significant decrease in the degree of the total symptom experiences. Conclusions: The results of this study provide evidence that standardized telephone monitoring is effective in relieving symptom experience and improving self-management in patients with heart failure over the course of telephone monitoring.

Objectives : The purpose of the study is to investigate satisfaction, awareness and utilization of dental telephone services in dental clinic patients. Methods : A self-reported questionnaire was filled out by 220 dental clinic patients in G metropolitan city from March 11 to September 27, 2013. The data were analyzed by a descriptive analyses, ${\chi}^2$-test and relevant factors were determined using logistic regression analysis by SPSS 12.0. Results : The experience rate of scaling was 68.0% and the average number was $1.04{\pm}1.13$. The experience rate of regular check-up was 41.0% and the average number was $1.01{\pm}1.29$. Satisfaction and utilization rate of scaling and regular checkup was higher than that in those who did not receive the services. The major variables influencing the experience of scaling were woman, utilization of dental telephone service and regular check-up were awareness, utilization of dental telephone service and reason of utilization of dental telephone service(preventive). Conclusions : The dental telephone service in dental patients improved oral health. Accordingly, it is necessary to develop the professional dental hygiene program for oral health in dental patients.

In this paper, we propose on objective evaluation model of telephone transmission qulity in order to estimate a satisfaction score regarding speech quality in a relephone network. As the degradantion factors of telephone transmission quality, this model takes into account transmission loss, noise, distortion, talker echo and sidetone. A performance index[PI] is introduced for five psychological factors affecting telephone speech qualty, and a Mean Opinion Score(MOS) is estimated from the sum of all Pis. The simulation results indicate theat the MOS obtained from the objective evaluation model is in good agreement with that of subjective evaluation.

Purpose: The purpose of this study is to identify the effects of telephonic counseling on burnout, depression, life satisfaction, and perceived physical health among family caregivers of older adults with dementia. Method: Subjects were randomly assigned into telephonic counseling group (n=21) and the comparison group (n=32). A weekly telephone counseling was conducted by research assistants for 12 weeks. T-test were used to answer the research questions. Result: 1) There were no significant differences between the two groups on the level of burnout, depression, life satisfaction, and perceived physical health after telephone counseling. 2) Spouse caregivers under the telephone counseling tended to report higher perceived physical health than comparison group at the post-test (t=-1.88, p=.08). Spouse caregivers under the telephone counseling tended to report higher emotional exhaustion and lower feeling of self achievement. 3) Daughter-in-law caregivers under telephone counseling showed increased feeling of self achievement, improved physical health condition, and decreased depression. Conclusion: This study showed potential effects of the problem-solving telephone counseling to improve perceived physical health and to reduce the level of burnout and depression. The findings suggest the necessity of screening most vulnerable subgroups of caregivers to increase the effectiveness of nursing intervention such as telephone counseling.

이 연구는 개방형 설문의 사전조사와 온라인 서베이를 사용한 본조사에서 수집된 자료에 근거하여 전화 이용에서 얻어지는 충족, 대인커뮤니케이션 매체로서 전화의 적합성, 그리고 전화의 통화상대와 면대면 접촉 상대간의 중복정도를 실증적으로 살펴보았다. 그 결과, 응답자들은 전화 이용에서 사교 정보 거래 오락 응급 안도 등의 충족을 얻고 있으며, 특히 여성은 남성보다 더 큰 충족을 얻는다는 점이 밝혀졌다. 또한 커뮤니케이션 상대가 윗사람이고, 당면한 커뮤니케이션상황이 부탁이나 조언을 구하는 등 인간관계상 부담이 큰 경우 면대면 접촉을 보다 적합하다고 인식한 반면 친구나 동료에게 단순 정보를 전달할 때는 오히려 이동전화기 더욱 적절하다고 인식하는 것으로 밝혀졌다. 또한 전화보다는 이동전화의 통화상대가 면대면 접촉 상대와의 중복도가 더 큰 것으로 밝혀져 이동전화는 즉시성 직접성이라는 매체 고유의 기술적 강점에도 불구하고 내집단의 경계를 뛰어넘는 집단간 커뮤니케이션보다는 내집단 성원간의 관계를 더욱 굳건히 하는데 주로 사용되고 있음을 알 수 있었다.

인터넷 전화의 사용이 증가하고 있고 최근에는 스마트폰이 보급됨에 따라서 스마트폰을 통한 인터넷 전화 서비스 이용이 급격하게 증가할 것으로 예상되고 있다. 특히 국내의 경우 이미 전국 상당 지역에 설치된 와이브로를 통한 인터넷 전화 서비스의 제공은 와이브로의 활성화로 이어질 수 있는 좋은 기회라 할 수 있다. 그런데 기존의 전화망이나 이동전화망을 통한 전화 서비스와는 달리 인터넷 전화는 서비스 품질이 보장될 수 없다는 문제점이 있고 특히 무선 환경을 통한 모바일 인터넷 전화 서비스의 경우 이 문제점은 더 심각해 질 수 있다. 따라서 보다 더 엄격하고 체계화된 모바일 인터넷 전화 서비스 품질 관리 방안이 마련될 필요성이 있다. 이를 향한 첫 단계로서 본 논문은 와이브로를 통한 모바일 인터넷 전화 서비스의 품질을 관리하기 위한 방안을 제안하고 이를 구현하기 위하여 개발된 소프트웨어의 개발 과정을 설명한다. 개발된 소프트웨어는 사용자 단말에 장착되어 전체적인 모바일 인터넷 전화 서비스의 품질을 VoIP 품질지표, 네트워크 품질지표, 무선 품질지표로 분류하여 측정함으로써 보다 효율적인 품질 관리가 가능하다는 장점이 있다.
