  • 본 연구는 2단계 학습자 개별 적응 평가시스템을 설계하고 구현한 것이다. 2단계 학습자 개별 적응 평가시스템이란 학습자의 학습 상태에 따라 필요한 문제지를 추출하여 동적으로 제공할 수 있도록 단원별 진단평가를 시행하고 학습된 결과를 저장하였다가 그 결과에 따라 기본, 보통, 심화 문제지군(群)을 구성하여 제공하는 단계형 학습자 개별적응 평가(CAT)를 설계하여 구현한 평가 시스템을 말한다. 본 학습자 개별 적응 평가시스템은 웹을 기반으로 하였으므로 지역적으로 흩어져 있는 교사들이 공동으로 문항을 제작함으로써 문항제작에 필요한 노력을 줄일 수 있고 학습자는 이를 이용해 개별학습의 효과를 얻을 수 있다.

  • Computerized spirometer was developed in a form of proto type system. The system consisted of pneumotachometer, flow measurement unit, fan ventilator unit, and software program. Patient's respiratory flow signal was first converted to corresponding pressure drop signal by a screen type pneumotachometer, sensed by a differential pressure transducer, amplified and low pass filtered, and digitized at a rate of 100 Hz, then fed into a PC thru RS-232C serial port. Customized application software controls data acquisition followed by computation of test parameters. The fan ventilator unit dries and eliminates microorganism in the pneumotachometer after each test. The system performs conventional spirometic tests and manages the test results in a database for retrograde research. The proto type system was fully developed and the commercialized system is currently being built up.

  • The purpose of this study was to develop a computerized software program to help for reproductive management in dairy cows. The developed software program in the study is compatible with a window 95/98 or XP system. Data in the system were recorded, stored, and processed from two sources: 1) Data downloaded monthly from the database of the Korean Dairy Herd Improvement Association (milk yields, milk somatic cell counts, milk fat, protein, lactose and urea nitrogen content). 2) Data recorded by the farmer or veterinarians by the time (body condition score, heats, inseminations, veterinary diagnosis and treatments). These data indices after processing by computerized dairy management system were presented by numerical or graphical display. The presented data were obtained from three dairy farms with more than 50 milking cows. The presented reports of this program using milk fat, protein, urea nitrogen, and somatic cell counts enabled the dairy producer and veterinarians to monitor the protein-energy balance and feeding management practice, and for distribution of diseases (mastitis, metabolic and reproductive disorder) in individual cows. The presented analytical reports of this program also included herd average of reproductive indices such as day to first insemination, days open, and inseminations per conception. This software program will assist in analysis, interpretation and demonstrate the results of reproductive trials conducted in dairy herds.

  • 본 연구는 전산화된 임상 데이터를 이용하여 환자 중증도를 분별하는 기법을 고안하고 간호사가 작성한 분류 점수와 비교 분석하여 타당성을 검증하기 위하여 일개 종합병원의 7개 병동 재원환자 348명에게 하루동안 간호사가 수행한 행위를 근거로 환자분류(KPCS-1: Korean patient classification system for nurses) 점수를 간호사가 작성하고, 병원정보시스템에 저장되어 있는 임상 데이터를 이용하여 산정, 수집한 점수와 비교하였다. 간호사가 작성한 점수와 임상 데이터를 이용한 환자 중증도 점수 모두 진료과 및 환자유형에 따라 점수 분포를 비교한 결과 유의한 차이가 있는 것으로 나타나 환자분류의 타당성이 동일하게 검증되었으며, 두 방법 간 에는 상관계수 0.96(p<.001)의 높은 상관성이 있었다. 임상 데이터 기법이 다소 높은 점수를 보였으나 일부 영역의 보완을 거친다면 간호사가 환자분류를 작성하지 않고, 병원정보시스템에 저장된 임상 데이터에 연동하여 자동으로 환자 중증도를 분별하는 시스템 개발이 가능하고 이를 간호인력의 성과관리 및 수급계획 등에 활용 할 수 있을 것으로 기대된다.

  • It is well known that multipoint and computerized intraoperative mapping systems improve the results of surgery for Wolff-Parkinson-White syndrome and show tremendous potential for opening an entirely new era of surgical intervention for the more common and lethal types of supraventricular tachyarrhythmias such as atrial flutter and atrial fibrillation. In addition, the ability to map and ablate the sometimes fleeting automatic atrial tachycardia is greatly enhanced by computerized mapping systems. In this study, we have developed 64 channel computerized data analysis system using microcomputer (Macintosh IIx) for basic research of electrophysiology and electrical propagation. The bipolar electrogram information is acquired from 64 cardiac sites simultaneously at a sampling rate of 1ksamples/sec with continuous and total data storage of up to 30 seconds. When the reference electrogram is selected and reference point is picked up, delay time from the reference point in displayed on two dimensional diagram of the heart. System design permits easy expansion to almost 256 simultaneous sites, This system is expected to enable us to study pathophysiology of cardiac arrhythmia and to improve the results of diagnosis and surgical treatment for cardiac arrhythmia.

  • PURPOSE. Accurate color matching of maxillofacial prostheses to skin is important for esthetics. A computerized color matching system specific to human skin has recently been developed. The purpose of this study was to evaluate the accuracy in color and translucency matching of the computerized color matching system across different skin colors. MATERIALS AND METHODS. The silicone was colored to simulate 28 different skin colors (n=5) to serve as "target skin colors". Using a spectrocolorometer (e-skin), color codes were determined for "replicate skin color" fabrication. CIELAB Delta-E between target skin color-replicate skin color pairs and translucency parameter were calculated. CIELAB Delta-E values were compared with one-way ANOVA and Tukey multiple-comparison. The agreement between $L^*$, $a^*$, $b^*$ and translucency parameter of target skin colors and replicate skin color were calculated by a two-way mixed average measures intraclass correlation coefficient. Translucency parameter of target skin color- replicate skin color pairs were compared with Paired t-test (${\alpha}=.05$). RESULTS. The mean CIELAB Delta-E value was 3.83 and significant differences were found among colors. The intraclass correlation coefficient showed excellent reliability for $L^*$, $a^*$, $b^*$ and good reliability for translucency parameter (P<.001). The mean translucency parameter of replicate skin colors was significantly higher than that of translucency parameter. CONCLUSION. The computerized color matching system specific to human skin was found to be reliable in terms of color and translucency between target skin colors and replicate skin color.
