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.

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.

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).

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.

In this paper, we apply a close loop transmit diversity scheme to IMT-2000 satellite systems, and investigate the performance of the scheme in both ideal and more realistic situations. We verify that the performance of the closed loop transmit diversity scheme is quite sensitive to errors in feedback information. However, we also show that the number of quantization bits for feedback information does not significantly affect the system performance when considering the feedback of phase information only. In addition, 2-bit quantized system achieves the better performance than 4-bit quantized system in terms of slot error rate.

김수관,조세인,권병곤,이상호 대한악안면성형재건외과학회 2002 Maxillofacial Plastic Reconstructive Surgery Vol.24 No.4
The neodymium:yttrium-aluminum-garnet (Nd:YAG) laser is most widely used for treatment of lesions affecting the oral mucosa. A pulsed Nd:YAG laser (SDL-300EN, Samsung Electronics, Korea) with a wavelength of 1.32㎛ was used. In all cases, contact mode was used. Four cases of soft tissue oral lesions are presented to document the clinical aspects. Surgery proceeded without complication and healing was uneventful. This study indicate that the Nd:YAG laser can be used successfully for intraoral soft tissue applications are well tolerated and minimal bleeding.

As the laser becomes more widely available in recent years, the oral and maxillofacial surgeon will have greater opportunity to use it for the treatment of soft tissue and hard tissue pathologies of the mouth. However, little information has been published on the bone. Dental lasers serve as an adjunct to regular treatments and enhancing outcomes in still others. The laser replaces conventional therapies with equal or improved results. Lasers offer new treatment options that heretofore were not available. Laser dentistry is capable of significantly minimizing discomfort, enhancing recovery times, and improving the overall efficiency of the dental office. We describe the basic researches and the developimg laser devices.
