최병석,오지훈,한성국 한국컴퓨터교육학회 2003 컴퓨터교육학회 논문지 Vol.6 No.4

대부분의 웹 기반의 교육 시스템은 교육 정보 제공에만 중점을 두고 있다. 웹이 점차 교육 정보를 제공하는 보편적인 기반이 되어 감에 따라서, 웹은 이제 정보 제공의 차원을 넘어 다양한 서비스를 제공하는 플랫폼으로 변모하고 있다. 이에 새롭게 변화된 웹 환경에 맞는 교육 서비스 모델이 시급히 요청되고 있다. 본 논문에서는 기존의 웹 기반 교육의 여러 한계성을 해결하기 위하여 새로운 기능형 중재자 기반의 교육자원 서비스 모델을 제시하고자 한다. 본 논문의 기능형 중재자기반의 교육자원 서비스 시스템은 웹상에 산재되어 있는 교육 자원들을 효율적으로 관리하고 사용자의 요청에 맞는 교육 서비스 정보를 제공하여 줌으로써, 교육 서비스 자원들의 재사용 효율과 생산성을 높일 수 있다 Most of web-based education systems are only to supply education information. As the web becomes the common basis to support the effective education, it is used for not only applying education information but also developing to the dimension to provide various services. The education service models prospering to the newly diverse environment are necessary. In this paper, a education resource service system based on functional broker is implemented to overcome the weakness of the traditional Web-based instruction. This paper shows that the web-based education service system such as functional broker can manage the varied education resources efficiently and so contribute to realize the life-long education.

To determine the factors affecting development and recovery of symptomatic vasospasm. the author analysed the results of patients with ruptured intracranial aneurysms treated by nimodipine and prophylactic “triple0H” therapy. From January 1991 to December 1995. 199 patients underwent surgery for ruptured intracerebral aneurysms. Combined hypervolemic hemodilution was initiated at the time of admission. Induced hypertension was added immediately after surgery(aneurysmal neck clipping). All patients received nimodipine intravenously or orally until the 14th day of SAH Sixty patients underwent surgery on Day 0 through 2 after attacks of subarachnoid hemorrhage(Goup A) 105 patients on Day 3 through 14(Group B). and 35 patients after Day 14(Group C). Of 199 patients. 76(38%) patients suffered from symtomatic vasospasm. Symptomatic vasospasm occured in 34% of Group A patients. 33% of Group B patients. and 5% of Group C patients. Symtomatic vasospasm occured more frequently in the older age group. the Fisher group 3 and Hunt & Hess grades 3, 4 and 5 groups. Of 76 patients who suffered from symptomatic vasospasm. 47(62%) patients recovered completely. The author analysed the relationship between recovery rate and sex, age. Hunt & Hess agrde and Fisher group among these 76 patients. Recovery rates between these groups were not significantly different. Based on this experience the author believes that Hunt-Hess grade. Fisher group and age are important factors affecting symptomatic vasospasm development.

배인국,장영남,채수천,류경원,최상훈 한국광물학회 2003 광물과 암석 (J.Miner.Soc.Korea) Vol.16 No.2

삼팔면체형의 스멕타이트계 사포나이트(saponite)를 천연 광물질인 활석을 이용하여 수열법에 의해 합성하였다. 출발물질은 활석에 Na₂CO₃를 첨가하여 공기중에서 800℃로 가열한 후, 화학양론적 조성에 맞게 Al(No₃)₃·9H₂O 및 Mg(No₃)₂·6H₂O 금속염 수용액을 첨가하였고, pH는 7∼12 범위 내로 NH₄OH 수용액에 의해 조절하여 제조하였다. 수열반응 조건은 약 1리터의 수열반응 용기에서 230 ℃, 압력은 25∼75 kgf/㎠의 범위 내에서 10∼60시간이었다. 실험결과, 반응온도 및 회전속도를 230℃와 180 rpm으로 고정시킨 수열조건 하에서 반응시간, 반응압력, pH 조건을 각각 40시간, 25 kgf/㎠, 약 10으로 하였을 때, 그리고, 화학조성을 화학양론적 조성에 필요한 Na₂O의 양보다 200% 과량 추가하였을 때, 양호한 사포나이트가 합성되었다. 또한 압력을 75 kgf/㎠까지 증가시켜도 결정도에 미치는 영향은 미미하였으며, 반응시간이 길수록 더 좋은 결정도를 나타냈다. Saponite was synthesized from talc by hydrothermal method. The starting material was prepared by adding Al(N0₃)₃·9H₂0 and Mg(N₃)₂·6H₂O solution to the talc powder, which was previously activated in air at 800℃ together with Na₂C0₃. The alkalinity of the solution was controlled by NH₄0H solution. The autoclaving was carried out in the closed stainless steel vessel (about 1 liter) for 40 hours under the pressure of 25 ㎏f/㎠ at 230℃. The characterization of the reaction product shows that saponite was crystallized successfully. After the experimental results, pressure was not sensitive parameter in the range of 25-75 ㎏f/㎠, but longer reaction time results in better crystallinity.

정상훈,최장우,김명래,이창국,김선종 大韓顎顔面成形再建外科學會 1996 Maxillofacial Plastic Reconstructive Surgery Vol.18 No.2

With the increasing esthetic requirement in orthognathic surgeries, midfacial corrective surgeries were developed to improve the paranasal depression. Augmentation with autogenous bones has long been the standard in facial reconstruction, however limited graft availability, donor site morbidity, and difficulties in 3-dimensional shaping were led to limited use. Porous high density polyethylene(Medpor) was introduced in the 1970s as an alloplastic implants. It can be used in various size and shapes, and shortend operation time. The purpose of this study is to determine, by means of cephalometrics, the degree of long term stability and gaining of the overlying soft tissue thickness. The results were as followings : 1. There was no evidence of foreign body reaction, infection, and tissue necrosis. 2. Medpor implants had an advantage of clinical use ; easy to contour and adapt to obtain a precise 3-dimensional construction. 3. Cephalometric study of 16 cases of paranasal augmentation revealed an overall increase of soft tissue thickness of approximately 82.1% in 6-months following. 4. The successful results could be obtained under the aseptic handling.

유행과정 이론에 관한 연구

김정실 경원전문대학 1999 論文集 Vol.21 No.-

When examining the topic of fashion for the first time, many people are fascinated with the contrasts in perspectives of the phenomenon. Psychologists speak of fashion as the seeking of individuality; sociologists see class competition and social conformity to norms of dress; economists see a pursuit of the scarce; aestheticians view the artistic components and ideals of beauty; historians offer evolutionary explanations for changes in designs. Literally hundreds of view-points unfold, from a literature more immense than for any phenomenon of consumer behavior. It is presented to show that complete theory that is interesting and imaginative can be organized from the building blocks offered by the behavioral sciences. Comprehensive synthesis of a fashion theory is the next step, and it is the giant step that will elevate fashion to its central and rightful place in the analysis of consumption. In this chapter, I outline a single conceptual model of the fashion process, describe different behavioral science approaches to modeling this fashion process, and show how these varied approaches can be unifield in a general fashion theory.
