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.

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.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

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.

An analysis is presented on the influence of the axial force and a moving elastic system at constant velocities on dynamic behavior of a simple beam. The compressive force is consevative, which remain in constant direction. A moving elastic system consists of spring, viscous dampers, a sprung mass, and an unsprung mass. The sprung mass is an elastic body supported at both ends by the suspension unite consisting of springs and viscous dampers, and assumed to be vibrated transvesly. The unsprung masses are the rigid bodies attached to the bottom of the suspension unit and moves, not seperating from a simple beam, at constant velocity on it. As the position of a moving elastic system moves to the right on a simple beam, the deflection of it is increased. The deflection of a simple beam is nearly influenced by the velocities of a moving elastic body in total mode. Since the spring force control the transverse vibration of a simple beam, the large force of spring decrease the deflection unit and a axial force influence infitesimally on the deflection of a simple beam.
