통신기술의 발전은 사용자에게 편리하고 다양한 서비스를 제공하여 왔으며, 사용자의 더욱 편리하며 다양한 서비스의 욕구를 만족시키기 위한 통신 기술이 계속적으로 발전해 오고 있다. 본 연구는 초고속정보통신망의 하부구조의 전송방식으로 채택된 ATM(Asynchronous Transfer Mode)기술을 이용하여 화상회의 및 원격교육 등의 멀티미디어 응용 서비스를 지원할 수 있는 서비스 플렛폼의 제시를 목적으로 하고 있다. ATM망은 광대역 종합 정보 통신망 내에서 일반 사용자들이 다양한 형태의 미디어 정보들을 서비스 받을 수 있도록 연결 통로 역활을 한다. 이러한 서비스 기능의 타당성을 보여 주기 위해서는 가입자 단말 장치 간에 다양한 미디어의 정보들의 상호 교환이 원활히 이루어지는 것으로 보여 주어야 한다. 이를 위하여 멀티미디어 기능을 갖는 단말 장치를 갖춘 시험 환경을 구축하며, 시험 환경을 통하여 ATM소형 스위치가 제공하는 점대점 연결 서비스와 이에 따를 멀티미디어 통신 서비스 기능이 정상적으로 이루어지는가를 보여준다. 본 논문에서 구축한 멀티미디어 서비스를 위한 ATM통신망은 현재 제품화된 소형 ATM스위치와 ATM단말기로 이루어진다. 특히 ATM단말기는 Sun SPARC station내에 ATM용 내장카드를 부착하여 구성하였으며, 멀티미디어 서비스의 시연을 위해서 화상 회의용 소프트웨어를 내부에 설치하여 시연을 하였다. 이러한 시연을 통하여 ATM망을 통한 멀티미디어 서비스의 지원 타당성을 시험하였다. Developing of communication technologies, users want the various service, such as text, image and video. The requirements stimulate the development of communication technologies. For the requirements, the communication technologies are continuously enhanced. In the paper, we suggest a service platform to support video conference and long distance education by using of the information infrastructure for B-ISDN(Broadband Integrated Service Digital Network). ATM (Asynchronous Transfer Mode) technology is adapted a basic communication protocol in B-ISDN. The ATM network can support a path to obtain the multimedia services between users. For the effects, we construct a testing environment that is based both ATM terminal and ATM switch for supporting the multimedia service. The ATM switch supports a point-to-point connection service between ATM terminals. The ATM terminals are constructed under SPARC station with ATM Adapted Card. The video conference application for multimedia services are demonstrated by using of the video conference software, i.e. Commuique made by Insoft Inc., ported in the ATM terminals. We verify the possobility of multimedia service based on ATM network.

The transfer matrix method is used to study the influence of the translational spring support on the transverse vibration of the simple curved beam. The translational spring supports are constituted by the middle point and the nine points at regular interval on the curved beam. The influence of the translational spring constants on the natural frequency of the simple curved beam is very much at 1st and 3rd mode and the natural frequency is augmented as increasing of the translational spring constants. Since the amplitude of the curved beam is small at high mode, the translational spring constant has a little influence on the transverse vibration of the simple curved beam. The simple curved beam supported elastically at middle point has high frequency than that supported elastically at nine points at regular interval. If the translational spring constant supporting the simple curved beam become very large, and then since the elastic support is similar to the rigid support, the transverse natural frequencies increase very much at the each mode of the simple curved beam.

Background : Little work has been carried out regarding quality assessment research in a primary care setting, comparing with that of hospitals. This study aims to evaluate the process of diagnosis and management of hypertension by public health doctors on the basis of pre-established clinical guideline, and to identify several modifying factors associated with them. Methods : Hypertension was selected as the target disease, because it is a chronic disease which is of great public health importance. Self-administered questionnaires were mailed to public health doctors practicing at health centers and health subcenters across the nation. The response rate was 20.9%. The questionnaire included the diagnosis and management process such as measuring blood pressure, history taking, physical examinations, and treatment approches and potentially modifying factors such as level of training, duration of practice as a public health doctor, and education on management of hypertension. Results : Public health doctors pay little attention in measuring BP, hypertension related history taking, performing physical examination and laboratory examination. But they devoted much effort in diagnosing hypertension exactly and giving nonpharmacological treatment. Among various antihypertensive drugs, calcium-channel blockers were the most preferred agent(50.8%). Level of training, duration of practice as a public health doctor, and education on management of hypertension made no difference on quality of care(p>0.05). Conclusion : These public health doctors showed poor compliance with the preestablished clinical guidelines, which leaves much to be desired in diagnosion and managing hypertensive patients by public health doctors. This study might be able to contribute to develop some strategies, such as educational programs, which would be able to improve the process of care in hypertensives.

Background: An appropriate use of hospital beds can improve productivity of hospital significanlly. The authors previous study revealed that approximately one third of Korean hospital bed days and one sixth of admissions were inappropritely used, when it was measured by Appropriateness Evaluation Protocol(AEP) and Delay Tool modified into Korean situation by the authors. This study aims to evaluate applicability of the instruments in a new hospital. More specifically the study aims to measure appropriateness of the instruments used by newly trained nurse reviewers at a new hospital setting. Methods: In order to evaluate applicability of these instruments, agreement rates of the scores recorded by newly trained nurse reviewers with by skilled nurse reviewer and also compared with the scores recorded by physician's implicit decision were assessed. Agreement rates were derived from concurrent application of AEP and Delay Tool to 52 admissions and 104 patient days from internal medicine, pediatrics, and general surgery of one university hospital. Oversall agreement rate, specific nonacute agreement rate, and kappa statistics were used to indicate level of agreement. Results: Overall agreement rates on appropriateness between newly trained nurse reviewers and skilled nurse reviewer were 100% in admission and 98% in bed days. Overall agreement rates on reason for inappropriateness between newly trained nurse reviewers and skilled nurse reviewer were 96% in admission and 91% in bed days. Overall agreement rates between newly trained nurse reviewers and physician reviewer were 86% in admission and 87% in bed days. Conclusion: Results indicated that AEP and Delay Tool were applicable to a new hospital in detecting inappropriate utilization of beds and reasoning of the inappropriateness. Thess instruments could contribute to enhance efficiency of hospital use, through continuous monitoring of level of inappropriate hospital use at national or individual hospital level.

국내 중증 만성정신질환자 수를 추정하기 위하여 일 농촌 및 대도시 지역의 지역의료보험 및 의료보호 대상자 중 1993년 1년간 의료기관에서 정신증 상병(ICD-9 code 상 290-299) 및 알콜 남용/중독, 성격장애 및 정신박약 진단하에 치료를 받은 적이 있는 사람에 대해 설문조사를 실시하였다. 연구자들이 개발한 진단도구를 이용하여 진단을 평가하고, Strauss-Carpenter scale 등을 이용하여 기능 장애를 평가하고 유병기간 등을 조사하였다. 결과를 요약하면 다음과 같다. 1) 진단평가상 정신분열병군(61.1%)이 가장 많았으며, 정동장애군(23.7%), 알콜장애군(11.2%), 기질성 정신장애군(4.0%)의 순서이었다. 2) 직업활동정도는 진단군별로 차이가 많았다. 지난 1년간 직업활동이 6개월 미만이거나 전혀 없는 환자 비율이 정신분열병군은 67.2%, 알콜장애군 52.0%, 정동장애20.8%의 순으로 정신분열병군이 가장 불량하였다. 3) 사회활동도 진단군별로 차이가 많아서 지난 1년간 의도적, 사회활동이 없는 비율이 정신분열병군이 가장 높았고(72.3%), 알콜장애군(32.0%), 정동장애군(20.7%)의 순이었다. 4) 국내 의료보험 및 사회복지시설 이용 자료 등을 토대로 본 조사 결과를 적용한 결과 국내중증 만성 정신질환자의 수는 약 8만 7천명으로 추산되었다. Objectives: The purpose of this study was to estimate the number of serious and persistent mentally ill patients in Korea. Methods : Study populations were recruited from medical insurance data of two district areas ; one rural and the other urban areas. Subject were all mentally ill who had ever visited any hospital in 1993 and were diagnosed as having psychosis, personality disorder and drug abuse. We conducted a home visiting survey applying semi-structured diagnostic interview, assessing the level of social adjustment with Strauss-Carpenter Scale, and past psychiatric history by the trained researchers, in October and November,1994. Results : According to diagnostic assessment schizophrenic patients constituted the major portion(61.1%) of study subjects. The distribution of occupational functions and social contacts was variable according to diagnosis. Most schizophrenic patients were unemployed or worked less than 6 months in the previous year(67.2%), and showed poor social contact(72.3%). But affective disorder patients were relatively independent in job maintenance and social relationship. Alcoholic patients lay between those of schizophrenic and affective disorder groups. It was estimated that about 87,000 adult Koreans were suffering from chronic mental disorders which seriously interfere with their daily life. Conclusions : Serious and persistent mentally ill patients were common in Korea. Community support program should be provided for them.
