A five year old female Yorkshire terrier dog with a history of hindlimb lameness was referred to the Veterinary Teaching Hospital of Chungnam National University. The patient had been treated surgically two times for patellar luxation in other animal hospital. On physical examination, hindlimb lameness, pain on left hindlimb and Lt/Rt medial patellar luxation (Grade Ⅲ) were observed. On the results of hindlimb radiographs, bilaterally medially luxated patella and degenerative joint disease (DJD) sign at both stifle joints were observed. According to physical examination and radiographs, it was diagnosed as bilateral medial patellar luxation (Grade Ⅲ). The left hindlimb of patient was surgically treated with trochlear wedge resection (TWR), tibial tuberosity transposition (TTT), patellar and tibial antirotational suture and lateral retinacular overlap. After the surgical treatment, the patient was slowly recovered.

생명윤리학의 출현배경과 접근방법

이상목 새한철학회 2001 哲學論叢 Vol.23 No.1

본 연구는 생명윤리학(bioethics)이 출현하게 된 사회ㆍ문화적 배경과 그것의 학제간 성격을 살펴보고, 또한 생명윤리학의 접근 방법론을 알아보았다. 생명윤리학의 출현은 첨단과 학기술의 발달과 문화적 변화에 의해 제기된 도덕적 혼란과 복잡성, 그리고 도전들에 어떻게 대적할 것인가에 대한 철학적 반성이다. 죽음의 판단 기준은 무엇인가 그리고 인간 생명의 조적 가능성과 생명 복제기술의 발달로 인한 인간 복제의 문제 등에 대한 바람직한 해결책이 요구되었다. 이에 대해 전통 윤리이론(공리주의, 의무론 등)은 너무 일반적이고 추상적이어서 이러한 구체적이고 복잡한 사례에 대한 해결책을 제시할 수 없기 때문에, 그 성격이 다른 도덕원리의 필요성에 의해서 나타난 새로운 학문분야가 생명윤리학이다. 그런데 생명윤리학은 어떤 하나의 원리나 담론이 주도하는 학문분야외 달리 철학, 윤리학, 신학, 의학, 법학 등 광범위한 토대를 가진 학제간(interdisciplinary) 탐구로 이루어 졌기 때문에, 그것의 적합한 접근방법이 요구되었다. 이에 따라 크게 세 가지 접근방법이 제안되었다. 하나는 전통 윤리이론과 같은 높은 수준의 근본원리에 의존하지 않고, 네 가지 중간수준의 원칙에 의존하는 접근방법이다. 그것은 인간에 대한 존경의 원칙, 피해 회피 원칙, 선행 원칙, 정의 원칙과 같은 네 가지 중간 수준의 도덕원칙을 우리가 처한 도덕문제에 적용시켜 도덕적 해결책을 추론해 내는 하향적 방법(upward-down)이다. 이러한 연역적 방법론의 대표적 도덕이론은 "원칙주의"(princiolism)이다. 다음엔 사례에 기초한 방법론으로서 이 방법은 우리로 하여금 사례들을 검토 그리고 재검토하도록 요청하고 그리고 그 사례들을 환경에 기초한 적합한 개념 혹은 공통의 도덕 격률 하에 있는 분류법으로 정돈한다. 이 방법은 구체적인 도덕문제에서 일반적인 도덕원리로 나아가는 '상향적 방법'(downward-up)이다. 이러한 귀납적 방법론의 대표적인 도덕이론은 "결의론"(casuistry)이다. 마지막으로 공동체주의에 근거한 방법론으로서 이러한 접근은 생명윤리학의 출발점이 개인보다는 공동체이어야 한다는 것이다. Beginning in the 1960s, the foundations of Hippocratic ethics came under a cross fire of criticism from a variety of sources as followings; Beginning in the 1950s' Remarkable technological developments opened up whole new sets of possibilities in medicine. The era witnessed the development of medical technology such as kidney dialysis, organ transplantation, and effective and safe contraception along with safe abortions. And the 1960s was a time of rebellion against formal authorities. The civil rights movement, the anti-Vietnam war caused large numbers of people to question paternalism in many spheres of life. The autonomy of the physician to determine what constitutes harm and benefit was likewise called into question. These changes significantly influenced the development of the field of bioethics. The discipline of bioethics is not unified by single dominant theory of methodology. It reflects the interdisciplinary features in bioethics. These highly inter-disciplinary discussions brought considerations from every side into the debate. The two disciplines, moral philosophy and moral theory, provided their skills for the debates. Gradually, scholars from the two academic disciplines that had traditionally studied morality, philosophy and theology, began to join the physician. However, They did not submerge the interdisciplinary features in any single ethical theory. Because bioethics has a practical end, to guide decisions and to shape policy, it is not rare that out of the welter argument comes substantial consensus. Many philosophers doubt that there can be a satisfactory ethical theory of the kind that philosophers have traditionally sought, because morality cannit be codified in a set of rules, Some have sought to resolve moral dilemmas by side-stepping these problems confronting foundational methods. One way is to drop the use of traditional ethical theory and guide the resolution of moral controversies by middle-level principles.-"principlism" Another way to approach the problems presented in traditional ethical methods is to address the problems of the specification of principles to particular moral controversies by working with particular moral cases.-"casuistry" And the limitation of different method in bioethics have led some in the field to search of a communitarian basis. This method argues that the starting point for bioethics ought to be the community rather than the individual. However, a consensus on methodological issues in bioethics seems an unlikely accomplishment, because people treat method in several way.

수압저하시 수압과 사용수량의 함수관계를 고려한 배수관망해석

이상목,현인환 대한상하수도학회 2003 상하수도학회지 Vol.17 No.6

The preassure drop below the desired level by pipe failures in water distribution network causes service failure and insufficient water pressure areas. To reduce inconvenience of consumer caused by water pressure drop, these areas need to be predicted accurately. This kind of prediction technique will allow network managers to take appropriate and rapid action, and thus improving the service quality of water supply. For more accurate prediction of the insufficient water pressure area, a functional relationship between water pressure and demand has to be considered. However, the conventional analysis method assumes that all nodal water demands are always constant, even though the water pressure is not sufficient to supply at each node. Therefore, pipe flows can not be estimated correctly, and the insufficient water pressure areas are overestimated than actual. In this study, a new analysis method that can consider the functional relationship between pressure and water demand is suggested. Also, the model network and the real network were analyzed by simulating various pipe failure conditions to compare the results from both methods. As a result, suggested method was found to be more applicable and more accurate for predicting the network behavior under insufficient pressure condition caused by pipe failure in the network.

능동소나에서 다중경로환경을 고려한 표적의 도플러 탐지

이수형,이철목,박상배,이평기 위덕대학교 산업기술연구소 2000 산업기술연구소 논문집 Vol.4 No.1

최근 능동 소나에서는 표적의 탐지 성능을 향상시키기 위하여 "높은 시간-대역폭곱"의 파형들을 사용한다. 표적까지의 거리와 표적의 속도를 추정하는 방법으로 FFT-기반 상관관계 기법이 많이 사용되고 있으나, 다중경로 환경에서는 운용자의 요구를 만족하기에 충분한 결과를 나타내지 못하고 있다. 본 논문에서는 다중경로 환경에서 직접경로 신호의 도플러 변이와 도달시간의 탐지 정확도를 높이기 위한 새로운 기법을 제안하였다. In modern active sonar, so-called "high time-bandwidth product" waveforms are used to obtain processing gain for improved detection performance. FFT-based correlation processing is used to detect doppler shift for velocity of target and arrival time, but obtained results are not enough to satisfy the operational needs in multipath environment. In this paper, the new algorithm is proposed in order to improve detection accuracy of doppler shift and arriving time of direct path in multipath environment. It is achieved since the replica is made with considering multipath.

Biocompatible Osteoconductive Polymer와 吸收性 Hydroxyapatite가 骨化에 미치는 影響에 關한 硏究 : A HISTOLOGICAL STUDY

李敏汀,李相喆,柳東睦 慶熙大學校 齒科大學 1995 慶熙齒大論文集 Vol.17 No.2

The purpose of this study was to observe the osteogenic effects of biocompatible osteoconductive polymer(BOP D.T.I. Co., U.S.A.) and resorbable HA(Osteogen ; Impladent Co., U.S.A.) in bony defected area In order to perform this study, 30 male rabbits, weighing about 2.5kg were selected. The 3x5x7mm sized defects were made on the both sides of the mandibular body and the defect was filled with blood clot in control group and with resorbable HA and BOP respectively in experimental groups. All experimental animals were sacrificed at the 3rd day and the 1st, 2nd, 4th and 6th week after operation. The mandibular body and surrounding tissues were removed out, deminerahzed, dehydrated and embedded. The histological observation of the specimens in light microscopic level was performed after Azan staining. The results were as follows 1. Osteoblasts were observed after a eek both in control group and experimental groups, and fibrous tissues were formed in bony defected area. Especially, new bone formation was observed earlier in BOP experimental group than in any other groups. 2. New bone formation was developed from the adjacent normal bone to bony defected area both in control group and experimental groups. And in experimental groups, new bone was infiltrated rapidly into the graft material than in control group and large amount of bone formation was observed. 3. Both in two experimental groups, the resorption pattern of the graft material was observed after 2 weeks, an materials were almost disappeared after 4 weeks. 4. After 6 weeks, bony defected area was occupied with new bone both in control group and in experimental groups, but bony density in experimental groups was higher than in control group, especially in BOP experimental group which showed more mature heating state.

As a society develops and a standard of living raises, the orthoganthic operation, the purpose of which is the harmony of oral and surrounding tissue, the improvement of the basal bony relations for stable tooth-support, and the improvement of facial appearance, generalized in our society. This is a clinical study on 135 patients who underwent orthognathic operation at the Dept. of Oral and Maxillofacial surgery, College of Dentistry, Kyung-Hee University during the last 5 years. The results were as follows. 1. The ratio of female to male was 1.4 : 1. 2. The age distribution of most patients was the period of 20 years thruogh 24 years. 3. The major reasons for seeking orthagnathic surgery were ethetic complanints(94.8%), and additional reason was functional complaints such as masticatory disturbances, phonetic disturbances, and TMJ discomfort. 4. In order to consult about orthognathic surgery, the patients first visited to the Dept. of oral and maxillofacial surgery at the ratio of 24.0%. 5. The ratio of the patients who underwent the presurgical orthodontic treatment was 79.5%, and the treatment usually required the period from 7 months to 18 months. 6. The setback amount was less than 10mm at the ratio of 85.8%. 7. The orthognathic operations which were practiced were usually composed of ramus osteotomy such as sagittal split ramus osteotomy and vertical ramus osteotomy and additional surgery on mandible at the ratio of 86.7%, and SSRO was done at the ratio of 62.5%, and EVRO was done at the ratio of 37.5%.

Although the use of the antibiotics has minimized the dangers of the spread of odontogenic infection to adjacent important organs, sometimes the fatal cases, such as Ludwig's angina, mediastinitis, intracranial complications from the odotogenic infection, may be occurred. The odontogenic infections or oral and maxillofacial region may involve the intracranial area through systemic circulation or by direct spread into the intracranial cavity. Headache, malaise, loss of appetite, chills, fever, vomiting, apathy, and irritability are usually followed by more specific involvement of the nervous system. We experienced one patient who died of intracranial complication from odontogenic infection. So we report the case and the literatures about intracranial involvements following odontogenic infections and dental procedures.
