김원영,김치수,김진수 한국컴퓨터교육학회 2002 컴퓨터교육학회 논문지 Vol.5 No.3

본 논문은 학교현장에서 학습자의 창의력 신장을 위해 멀티미디어 교육을 지원하는 웹 기반 실시간 교육 시스템을 제안하였다. 제안된 시스템은 교수·학습자간의 실시간 상호작용과 개별학습, 학습자의 학습일탈을 방지하기 위한 강제화면 분배를 지원할 수 있게 설계되었다. 본 시스템은 UML을 적용하여 다중 사용자 환경에서의 실시간 메시지 교환과 관리를 위한 모듈을 두어 효율적인 상호작용이 가능하게 하였으며, 학습자의 실험·실습을 위한 시뮬레이션이 이루어지고 실험의 방법과 결과분석 등에 대한 질의 응답을 지원한다. 학습자의 학습진행과 지식형성을 위해 시스템의 교육적 기반을 구성주의에 두었다. In this paper a web-based real-time education system, which is able to support education through multimedia, is suggested for the expansion of learner's creative ability in the school. This system is designed so that it can support three things: 1) a real time interaction between instructors and learners, 2) individual learning through such an interaction, and 3) a coercive distribution of display by instructions for preventing the deviation of learners from learning. Also, this system, which UML is applied to, makes efficient interaction possible through the module for the real-time exchange and management of messages even in the multi-user environment. Through this system, not only the simulation by learners can be made for experiments and practices, but also questions and respondence can be supported on the procedure of experiments and the analysis of their results. This system is built on constructivism, and aimed at helping the learning progress and knowledge formation of learners.

이현숙,김수연,김명희,김정환,방은치,강용인,조경숙,김수연 대한산부인과학회 2000 Obstetrics & Gynecology Science Vol.43 No.12

목적 : 무통분만을 위해 시행한 지속적 경막외제통이 분만에 미치는 영향을 살펴보고자 하였다. 연구방법 : 분만시 통증경감을 원하는 산모를 두군으로 나누어 자궁경부가 3-5cm 개대시 1군 산모 35명은 0.0625% bupivacaine과 0.2㎍/㎖ fentanyl을 혼합하여 지속적 경막외제통을 시행하였고, 2군 산모 43명은 nalbuphine 10mg을 근주하였다. 1군과 2군에서 분만 1기와 2기의 진행시 소요된 시간, 제왕절개술의 빈도, 신생아의 Apgar score 및 체중을 기록하였고 통증 정도는 0-100mm의 시각통증등급에따라 측정하였다. 통계는 모수검정에는 independent t-test, 비모수검정에는 chi-square test를 이용하여 p〈0.05인 경우 통계적 의의를 두었다. 결과 : 1. 1군에서 분만 1기와 2기가 연장되었지만 통계적 차이는 없었다. 2. 신생아의 체중 및 Apgar score는 두 군간에 차이가 없었다. 3. 제왕절개술의 빈도는 1군이 16%(7/35), 2군이 14%(6/43)로 두 군간에 유의한 차이는 없었다. 4. 통증정도는 1군에서 유의하게 낮았다. 결론 : 분만진통시 시행하는 경막외제통은 분만의 진행과정에 지장을 주지 않았고 제왕절개술의 빈도도 높이지 않았다. 경막외제통은 태아나 산모에게 안전하게 시행될 수 있으나 산모선택이나 마취방법, 산과적 수기에 세심한 주의가 필요하다고 사료된다. Background : The effect of epidural analgesia on the progress of labor is controversial. The objective of this study is to determine the effect of analgesia on the outcome of labor, especially cesarean delivery rate in the epidural group and non-epidural group, prospectively. Methods : All the parturients were divided into two groups, group 1(epidural group, n=35) and group 2(non-epidural group, intramuscular nalbuphine, n=43) randomly. Epidural analgesia was maintained with a continuous epidural injection of 0.0625% bupivacaine with 0.2 ㎍/㎖ fentanyl in the group 1 and nalbuphine 10 ㎎ was intramuscular injected in the group 2 when the cervix was dilated to at least 3-5 ㎝. The duration of first and second stage of labor, cesarean delivery rate, Apgar score and body weight of baby were recorded and pain score of parturient was recorded by 0-100 ㎜ visual analog scale. Results : The duration of first and second stage labor were prolonged in the group 1. But there were no significant differences in the duration of first and second stage labor, Apgar score and body weight of baby between the two groups. Cesarean delivery rate was 16%(n= 7/35) in the group 1 and 14%(n= 6/43) in the group 2, so there was no significant difference between the two groups. Pain score was significantly lower in the group 1 than the group 2. Conclusion : Epidural analgesia was not associated with increased cesarean delivery rate and provided safe and effective intrapartum pain control. Maternal-fetal factors and obstetric management, not epidural analgesia, are the most important determinants of the cesarean delivery rate.

Deep burns of the face & lips often lead to scarring and contraction of the circum-oral tissues with a marked reduction in the size of the oral aperture. Such burns most commonly caused by electrical contact, for example, children sucking electric plugs, or as a result of chemical burns and the exposture to flame. Once having burns, burned tissue may contract and reduce considerably the size and mobility of the mouth ; therefore bring up the resultant functional disturbance, verbal difficulty, even disgestive difficulty, and poor appearance, which fall into difficulty in social acceptability, caused by burns. In our department, 2 patients who were complain of functional limitations and esthetic problem owing to scar contracture, were visited, and we treated this microstomia with scar excision, graft and flap technique, and postoperative intensive physical therapy. We obtained relatively favorable results, thus report this cases with literature review.

VRML 구현 모델을 위한 VTADL 개발

김치수,김성현 公州大學校 工學硏究院 生産技術硏究所 2004 論文集 Vol.12 No.-

Software architectures may be described using text-based architecture description language(ADL). The key goals of an ADL are to communicate alternate designs between different stakeholders, to detect reusable structures, and to record design decisions. This dissertation provided a solution to the representation problem by creating a tool for three-dimensional representation of architectural viewpoints. The tool consisted of an architecture description language(VTADL) to first describe the software architectures and viewpoints on the architectures; and a VTADL-to-VRML translater to translate each viewpoint into a separate virtual reality world. The goal of the dissertation was to devise algorithms for translating an ADL into effective VRML representations based on the desired viewpoint. The VRML representations were intended to enhance comprehension on the overall design and to improve communications between diverse stakeholders.

Transbronchial lung biopsy(TBLB) is a relatively simple and convenient diagnostic tool in solitary pulmonary nodule(SPN) on chest radiograph, which is cannot be diagnosed through routine tests. To investigate the diagnostic value and diagnostic rate of TBLB according to the variable factor, we analyzed 69 patients with radiologically SPN lesion on chest radiograph which was confirmed histologically. A histologic diagnosis of TBLB was made in 47 of 69 patients(68.1%), in which 26 of 37(70.3%) with malignancy and 21 of 32(65.6%) with benign lesion. There were no significant differences in diagnostic yield according to age, sex and location of the lesion. The diagnostic rate tended to increase with the more than 5 pieces to acquired by TBLB. When the size of SPN was less than 3 ㎝, it cannot be diagnosed. In conclusion, TBLB is a diagnostic procedure with good yield and safety, but percutaneous needle aspiration, transbronchial needle aspiration, and bronchial washing fluid cytology may be a complementary procedure to overcome the limitation of TBLB and get higher diagnostic yield for SPN.

This study was conducted to investigate quality characteristics of Aster scaber to increase the value of functional food resources. To examine quality characteristics of Aster scaber, various factors such as color, texture, fiber, minerals, tannin, crude proteins, crude lipids and sensory quality were determined using physiochemical methods. The contents of dietary fiber were 0.68 g in each 100 g of Aster scaber (freeze drying base). In mineral contents, iron was the highest value in Aster scaber (freeze drying base). The contents of tannin were 35.6 ppm of Aster scaber (fresh base). Aster scaber was shown significant difference in tannin from freeze drying leaf. From the results of sensory evaluation, the age of 30's and 40's showed a better acceptability in blanching. Functional healthy drinks were made from extracts of Aster scaber for relieving thirst and promoting health. The recipe of drinks were decided to establish manufacture condition through the sensory evaluation, color, flavor, taste, and overall acceptability. The shelf-life was established in 18 months through quality was analyzed such as soluble solids, optical density 480, pH, acidity and microorganisms.

Dens evaginatus is a rare developmental anomaly in which an enamel-covered tubercle projects from the occlusal surface of a tooth. usually lower second premolar. When the tubercle fractures, the pulpal extension into the tubercle may be exposed, which results in early pulpal necrosis, periapical infection and even osteomyelitis. We found the dens evaginatus in 16-week-old fetal mandible. Microscopically, we observed the protrusion of dental papilla into the dental organ and hard tissue formation which will be the tubercle by serial section. This anomaly was reported to be very rare in tooth development of fetus, so we reported this finding with brief review of literatures.
