전병광,손원근,서구원,맹학영,김동철,송해영 충남대학교 공업교육연구소 1994 論文集 Vol.17 No.1

Sulfonated poly(phenylene sulfide)(S-PPS) was prepared by the reaction of poly(phenylene sulfide)(PPS) with fuming sulfuric acid. The sulfonation was confirmed by the high intensity band of the SO_3H group at 1190 cm^-1. Thermally crosslinked S-PPS was used for a cation exchange polymer with high thermal stability. The ion exchange capacity of soluble S-PPS(H-form) and insoluble S-PPS(H-form) was 5.16meq/g and 3.50meq/g, respectively. The ion exchange capacity and IR absorbance at 1190cm^-1 of S-PPS were decreased as the curing temperature was increased.

Worst-case execution time(WCET) is part of the timing analysis of real-time systems. The goal of timing analysis is to validate that a real-time computer system fulfills the specified temporal requirements of a given application in all predicated situation. In this paper, We illustrate a new language, Timing-C, and design a timing tool for predicting WCET in it. Timing-C is added time constraint and a few restriction in the subset of C. Using Timing-C, programmer need not learn a new language and can demonstrate program's timing activity.

The purpose of this study is to identify specification required in the course of applying S/W quality metrics to real-time processing system. The approach this study took to define S/W quality is summerized as follow ; o S/W quality is based on user's need. This need can broken down three orientations, namely, - product operation. - product revision. - product transition. o S/W quality comprises eleven quality factors grouped according to three orientations. Each of these S/W quality factors describes one facet of quality and is comprised of several S/W quality metrics, of S/W quality criteria as they are sometimes called. S/W quality metrics are only useful in a format that lends itself to the persons jobnamely, management, system analyst and programmer-during requirement definition, design and code phase. This study identifies the different jobs and potential ways of presenting S/W quality metrics to aid decision making, product improvement, and quality control. This study identifies quality characteristics in real-time processing system, namely, o reliability and security o eseiness for maintainability o observance of response time o adaptability o secret protection o eseiness for use Each of these characteristics should be concerned with the different S/W quality factors and criteria. Now, I need to make every effort of the research and the method of quantifing S/W quality factors and criteria and developing computer-aided tools for supporting S/W measurement framework.

Fibrous dysplasia is an idiopathic skeletal disorder in which medullary bone is replaced and disturbed by poorly organized, structually unsound fibroosseous tissue, which may produce cortical expansion. When facial bones are involed, considerable esthetic deformity may result. The term monostotic fibrous dysplasia has been applied when one bone is involved : when more than one bone is affected, the term polyostotic used. The polyostotic form may be accomplished by pigmented skin lesion (Jaffe type), or by pigmented skin lesions with endocrine disturbance (Albright syndrome). No general agreement exists on the cause of fibrous dysplasia. A few authors have suggested that fibrous dysplasia arises as a resujlt of trauma. It occurs predominantly in infant, adolescent females and runs a variable clinical course. When several bones are involed, it tends to be unilateral. Involements of alveolar bone may produce displacement of teeth with malocclusion, or loss of teeth, or both. Radiographycally, ti shows an indistinctly delimited osteolytic defect with a bubble - like pattern, but without a sclerotic rim. The preferred treatment is almost always surgery. If the lesion is extensive, surgical intervention with use of recontouring procedures aimed at the correction of esthetic or funtional disturbances is preferred treatment. Now, we present a case of fibrous dysplasia on the left maxilla and the zygoma treated by bony contourign via hemicoronal flap and intraoral approach with good results.

『辨證奇聞』의 醫學的 特徵에 關한 考察 : 傷寒門을 중심으로 In view of ShangHan

이원석,박선동,박원환,김준기,김종대 동국대학교 한의학연구소 1998 東國韓醫學硏究所論文集 Vol.6 No.2

『辯證奇聞』은 淸代(1687年) 陳土鐸이 著述한 醫書로서 126門의 형식으로 이루어져 있다. 내용을 보면 한의학적 理法方藥의 논리체계를 제시하였다고 볼 수 있다. 明末淸初이후 중국에서는 實證的인 學風의 등장에 따라 歷史理論에 대한 비판 및 정리작업이 활발히 이루어지기 시작하였으며, 이 시기에 저작된 『辯證奇聞』은 현재 우리나라 臨床家에서 널리 膾炙되고 있는 秘方과 관련된 醫書중의 하나로 이에 대한 내용을 정리함으로서 현대와의 연계를 도모해 볼 수 있었다. 주로 腑臟辯證論治에 대한 시각에 입각하였고, 「傷寒論」을 보완하면서 비판한면도 찾아볼 수 있었다. 약물은 體內의 津液損傷與否를 살펴 사용하였다. In order to find the characteristic medical mothods of 『BianZhengGiMun』by the author ChenshiTo, we have translated and analyzed the mentioned book. Upon analyses, the following facts were noted: 1) 『BianZhengGiMun』is written and composed of case studies. Prescriptive methods described here differ rather from previously known methods, where as our nation's Oriental medicine practioners refer and consider these methods as miraculous modern methodologies. 2) Book's content has much similarities to 『ShangHanLun』's original text. Moreover, the content is adjusted towards presenting methodologies not covered in 『ShangHanLun』's text, together with adding more information to converse 『ShangHanLun』's methods as well as to critique them. 3) Diagnostic methods mainly follow the ZangFuBianZheng(朧腑辨證)'s pattern, where it's recorded information and theories are valid. 4) 『BianZhengGiMun』's prescriptive methods usually follow BuYinShengJin(補陰生津)'s form, where they were appropriate for that period and circumstances. 5) In consideration of all of the above factors, ChenShihTo grasped ShangHan and WenBing(acute febrile disease due to exogenous factor) as WaiGanReBing(外感熱病)'s double sided characteristics, where this corresponds with the current belief. It is believd that this in turn would provide much practical value to the present time.

본 연구에서는 현재 임상에서 home bleaching을 위해 사용되고 있는 표백 재료들이 치아 법랑질의 투명도에 어떠한 변화를 일으키는지 고찰해 보고자 시행하였다. 실험 대상으로는 하루 전 발거한 우치 (bovine tooth)를 사용하였다. 치아의 순면에 수직되게 다이아몬드 드릴을 이용해 수주 하에서 직경 6 mm의 원통형 치아 시편을 만들어 순면이 노출된 상태로 투명한 아크릭 레진에 포매한 후, low speed diamond saw (Isomat, Buehler Co., USA)를 사용하여 1.2 mm 두께로 절단하였다. 절단된 시편은 순면을 먼저 편평하게 연마하고,절단된 면을 연마하여 두께 1 mm의 시편을 완성하였다. 완성된 시편(우치 25개)을 무작위로 추출하여 3개의 그룹으로 나누고 나머지는 대조군으로 하였다. Opalescence (10% carbamide peroxide, Ultradent, Milford, USA), Rembrandt (10% carbamide peroxide, DenMat, USA) 및 Opalescence F(15% carbamide peroxide with fluoride, Ultradent)를 시편의 순면에 1주일 동안 적용 (표백제는 24시간마다 교체)하였고, 설측면은 증류수를 적신 거즈에 접촉된 상태로 보관하였다 표백제를 적용하기 전과 적용 3, 5, 7일째에 시편의 삼자극치 X, Y, Z 값을 색채색차계 (Color & Color Differencemeter, Model TC-6FX, Tokyo Denshoku Co., Japan)로 백색 배경판과 흑색 배경판 상에서 측정하였다 백색 배경판과 흑색 배경판 상에서 측정된 Y값의 평균값을 이용해 contrast ratio를 계산하였다 얻어진 값을 One Way Repeated Measured ANOVA를 이용하여 통계 처리한 결과 10% Opalescence처치군, 15% Opalescence-F처치군 및 대조군에서는 통계적으로 유의할만한 증감을 보이지 않았고, Rembrandt처치군에서는 Contrast ratio가 증가하였다 (p < 0.01) . This study was done to evaluate whether vital bleaching agents could influence on the translucency of the bovine enamel. The anterior bovine teeth that were extracted one day before and without any gross discoloration were obtained and then were preserved in physiologic saline. 6 mm cylindrical tooth specimens were fabricated with diamond puncher perpendicularly on labial surface of bovine tooth. After embedded in transparent acrylic resin with labial surface being exposed, they were cut to a thickness of 1.2 mm with low speed diamond saw (Isomat, Buehler Co., Lake Bluff, IL, USA). They were smoothly ground to 1 mm thickness of enamel with sandpaper. 24 specimens were randomly divided into 3 groups and control group respectively. Opalescence (10% carbamide peroxide, Ultradent, South Jordan, USA), Rembrandt (10% carbamide peroxide, DenMat, USA) and Opalescence F (15% carbamide peroxide with fluoride, Ultradent, USA) were applied on labial sides of the bovine enamel for 7 days (bleaching agents were reapplied every 24 hours) and the opposite surface was contacted to cotton that soaked in distilled water. The control group was soaked in distilled water. Three stimulus value X, Y and Z were evaluated with colorimeter (Color ' Color Differencerneter, Model TC-6FX, Tokyo Denshoku Co., Japan) on the labial surface of all specimen three times on white and black background plate before the bleaching agents were applied and on 3rd, 5th and 7th day after applied. The degree of translucency was normally assessed by measuring the inverse property, opacity (contrast ratio). 10% Opalescence, 15% Opalescence-F, and control group showed no significant variation in the translucency of bovine enamel, However Rembrandt decreased the translucency of it (p < 0.01).

This study aims to review the research trends concerning apartments and multi-family housings. Apartments and multi-family housings are the big rates of residence in the cities including Seoul in Korea. Since 1970s, it had happened because of overpopulation, the lack of building sites and inflated land prices. It spreaded big cities to the suburbs, starting from the 21st century. The size and the types of housings are becoming more and more various and evolved. People need variegated and efficient places to live because their lifestyle have become complicated and diverse. The requisite for improving the quality of residential environment are not only using luxury materials or enlarging spaces, but also requesting psychological, and social economical satisfaction. It profound studies are demanded about the residence. The residential environment is an area that contains personal lifestyle and directly affects tenants' behavior and expectation. The scope of review is limited to the articles listed in the Journal, Korean Institute of Landscape Architecture and the Architectural Institute of Korea. This research ranges from 1985 to 2006 June, where the studies on apartments were seriously started.
