李鉉澤,鄭聖寬,林元炫,鄭東煥 慶北大學校 1988 論文集 Vol.46 No.-

This study was to establish a basic theory of facilities. In this study, establishment status, users' actual conditions' senses were investigated about bench in KPNU. The main results of this study were as follows: 1) The bench type was classified 6 types. They were named as bench shape.. Rentangle (87.0%) was established the highest. And concrete(47.0%) was the highest in case of materials. Backboard was all much the same number in case of established(46.5%) and unestablished(53.5%). 2) There was not bench size standard and most of benches were unfit to the humanscale. It indicated that bench, design and construction must consider the humanscale. 3) Bench was used for rest and talks(85.0%). Arrangement direction of bench was considers and more bench for rest was constructed in the future. 4) 2-3 persons (76.0%) was the highest in bench users and 3-4 persons (50.0%) who use the other places was the highest in case of user group. It suggested that bench for 2-4 persons was needed for bench users. 5) In the post-occupancy evaluation, design, color, and number of bench were evaluated below the normal. Especially, concrete bench (non backboard) was evaluated negatively in convenience, harmony with surroundings, design, and quality of material. More benches were needed and design, color, convenience, quality of material, and harmony with surroundings were considered convenience, quality of material, and harmony with surroundings were considered in bench construction. In conclusion, this study was researched only one facilities, but study with various facilities in various sites (school, park, amusement park, street, and parking area) were needed in the future.

대학 공문서 표준화를 위한 SGML DTD 개발

이봉주,강성수,강재관 경남대학교 신소재연구소 1999 論文集 Vol.11 No.-

정보화 시대를 맞이하여 방대한 양의 문서를 어떻게 표준화 전자화할 것인가가 중요한 문제로 대두되고 있다. 본 논문에서는 대학에서 사용되는 여러 가지 공문서에 대한 STMLDTD를 개발하였다. 먼저 대학 공문서의 유형을 분류하고 유형별 공문서에서 논리적 엘리먼트를 추출 정의한 뒤 이용자의 문서 이용 형태를 분석하여 DTD 생성에 반영하였다. 분석된 공문서의 구조는 DTD 저작도구를 이용하여 DTD 문서로 변환하였다. In this paper. prototype SGML DTDs for university official documents are developed. The official documents are first classified according to their attributes. and the most frequently used documents are selected among them for analysis. The structures of the documents are analyzed by document analysis methodology, and their SGML DTDs conformant to IS0 standard are developed. A DTD authoring tool is engaged in parsing the developed DTDs.

이승관,이창규,조경진,김상애,김재영,이국성 高麗大學校 倂設 保健大學 保健科學硏究所 2000 保健科學論集 Vol.26 No.1

Pulsed-field gel electrophoresis (PPGE) has been employed as a tool to study correlation between apparent clinical features and genotyping of Group B Streptococci (GBS) infection. The result of serotyping among 45 isolates showed that serotype la, lb, Ⅲ, Ⅳ, Ⅴ, NT (nontypeable) were 15.5%, 11.1%, 35.5%, 2.22%, 20%, 15.5%, respectively. The result of serotyping for infection group of 26 isolates showed that serotype la, lb, Ⅲ, Ⅳ, Ⅴ, NT were 11.5%, 15.4%, 34.6%, 3.8%, 11.5%, 23%, respectively. The result of serotyping for carrier group of 19 isolates showed that serotype la, lb, Ⅲ, Ⅴ, NT were 21%, 5.3%, 36.8%, 31.6%, 5.3%, respectively. Thus, the predominant serotypes of the infection groups were serotype lb and Ⅲ, and those of the carrier groups serotype Ⅲ and Ⅴ. All isolates were characterized by PFGE analysis. Isolates were assigned to three major phylogenetic Divisions (Ⅰ, Ⅱ, Ⅲ) and subsequently to 16 PFGE groups (A[A1, A2, A3], B[B1, B2, B3], C, D[D1. D2, D3, D4, D5, D6], E[E1, E2], F). Seventy five percentages of Division Ⅰ belonged to the infection group. Seventy eight percentages Division Ⅱ of belonged to the carrier group. One hundred percentages of Division Ⅲ belonged to the infection group. The study on the correlation between genotype and serotype among the isolates showed that serotype Ⅲ was predominant in A1 group (5 of 5 isolates), D1 group (4 of 5 isolates), and F group (2 of 2 isolates). In addition, serotype Ⅴ was the sole serotype in C and D5 group. Those results indicated that serotyping and PFGE group analysis were highly correlated.

중합방법이 다른 의치상 레진의 적합도 평가

이상건,송윤관,송광엽 대한치과기재학회 1999 대한치과재료학회지 Vol.26 No.3

In addition to continuing the search for more accurate and dimensionally stable materials for denture bases, recently several processing methods for denture base resins which may reduce dimensional change during fabrication has been developed. The purpose of this study was to compare the dimensional accuracy of denture bases cured by four denture base processing methods, using the conventional heat-compression molding method, the continuous-pressure injection method, the microwave curing processing method, and the Sulfone system. A metal die simulating a maxillary edentulous arch and a polyvinylsiloxane impression(Reprosil, L. D. Caulk Co. U.S.A.) were used to construct 40 simulated master casts and denture bases with artificial teeth. Forty simulated denture bases 3 to 4㎜ thick were processed by four denture base processing methods following the manufacturer's instructions. The processed denture bases and casts sectioned through the posterior palatal region to allow measurement of its change by means of an travelling microscope. Observations were made on center of posterior palatal sectioned region. One-way ANOVA and paired samples t-tests were employed to compare the differences in distortion after deflasking and after finishing and polishing. The obtained results were as follows; 1. After deflasking, dimensional changes were diminished in order of conventional heat-compression molding, Sulfone system, continuous-pressure injection method, microwave processing method(p<0.05). 2. After finishing and polishing, dimensional changes were diminished in order of conventional heat-compression molding method, Sulfone system, microwave processing method, continuous-pressure injection method. The significant difference was found between conventional hear-compression method, continuous-pressure injection method(p<0.05). 3. The significant difference was found between after deflasking and after polishing in all methods, except continuous-pressure injection method(p<0.05).

유기인제 급성폭로후에 발생한 지연형 신경장애 1례

김탁관,이동철,김상범 동국대학교 경주대학 1993 東國論集 Vol.12 No.-

A relatively healthy 64-year-old man who ingested organophosphorous insecticide in an attempt to commit suicide was brought to the emergency room by his family members showing mental change and respiratory arrest. He suffered from delayed onset of generalized muscle weakness, body balance loss and respiratory difficulty that developed on 3 days after admission, and then he was supported by mechanical ventilation. We concluded that his final diagnosis is delayed neurotoxicity after carefully examining his neurologic status and electromyography. We have no data from nerve and muscle biopsy but we think delayed neurotoxicity in present due to compatible findings of clinical features and electrodiagnosis report.

근원세포 분화조절 유전자의 클로닝

강성구,이채관,김상해,김정락 인제대학교 1992 仁濟論叢 Vol.8 No.2

배아의 근원세포는 분화가 진행 됨에 따라 성체의 골격근 세포로 된다. 이러한 분화단계에는 특정 유전자가 관여할 것으로 추정되며 이전 실험에서 0.8Kb의 cDNA를 확인하였다 (Kang et al., 1992). 이러한 특이 유전자는 계배 부화 9일째부터 발현이 되었으며 성체에서는 발현이 되지 않았다. 특히 12일과 14일 계배의 뇌,간,신장조직에서는 유전자 발현이 되지 알았으며 단지 가슴근육조직에서만 유전자 발현이 되었다. 이 유전자는 계배 골격근 세포의 분화에서 중요한 역할을 할 것으로 추정된다. Embryonic myoblasts become determined to differentiate into distinctive types of muscle cells. Skeletal muscle cell is one of them. We studied the expression of muscle specific 0.8Kb cDNA related to the differentiation of chick embryonic myoblast in various stage of development and in organs. The gene was expressed from 9 day old chick embryo stage, but was not expressed at adult breast muscle. Also the gene was not expressed in brain, liber, kidney but expressed in 12 and 14 day old chick embryonic breast muscle. Therefore, this muscle specific gene(0.8Kb) may have an important role in regulating the diffrentiation of chick embryonic myoblast.
