Muscle proteins of the Korean gudgeon of the subfamily Gobioninae were investigated by the polyacrylamide gel electrophoresis to determine the relationships among the species and genera studied. The number of bands were varied between 8∼13, and the mobiltiy and density or width of staining were appeared to be specificity. Judging from the genera Pseudorasbora and Puntungia are closely related each other, but Gnathopogon and Squalidus which were previously known to be cospecific genus were conspicuously difference between them. The muscle protein electrophoretic patterns was provided to be confirmed the phyletic groups adopted for the subfamily Gobioninae by Banarescu and Nalbant in 1973.

Traction is the treatment of choice for a small nuclear protrusin. The nucleus is soft and can be influenced by suction. Traction provides a method of improving on recumben-cy-the only effective treatment before traction was devised. The intention is to achieve rapid reduction by distraction the joint surfaces mechanically-a positive purpose-instead of merely avoiding the compression of the upright posture by putting the patient to bed and leaving him there. Recumbency, usually successful in the end, wastes an endless amount of the patient's time and money. Traction carries the further advantage of enabling th epatient to be up and about, attending to his bussiness, during treatment. Traction brings the joint surfaces much farther apart than just lying in bed, a greater centripet force acts on the protruded part of the nucleus. Traction has three beneficial effects; 1. Suction : a sub-atmospheric pressure induces a centripetal effect on the contents. 2. Distraciton : increase the distance between the articular edges. X-rays have shown an increase in width of the joint of 2.5 mm. 3. Ligamentous tightening : the posterior longitudinal ligament tightens which then exerts centipetal forde on a central protrusion.

Markolf and Morris suggests that the deranged disk and torn annulus have an exellent re-covery ability from the position of spine extension, where the posterior annulus is not under stress and the gel can move anterioly. McKenzie explains side gliding as a combination of rotaion and side bending, his clinical studies indicate that side-gliding can gel laterally. In conclusion, the prone unilateral traction on the opposite side from the patient's pain along with the other treatment appered to have helped reduce those patient's pain. The method of treatment described in this report is suggest-ed for Korean physical therapists who treat patients suspected of posterolateral herniated nu-cleus pulposus.

객체지향 개념 모델링에서 OCL에 의한 상속성 원리

이지연,최병문,이영환 대전대학교 기초과학연구소 2003 自然科學 Vol.14 No.1

OOA/D에서는 클래스의 일반화와 특수화의 계층구조 사이에서 상속성의 개념이 어디까지 보장되는지 명확한 규칙이 없다. 예를 들어 상위 클래스의 제약조건이 하위 클래스에도 상속되는지, 상위 클래스의 상태 다이어그램이 하위 클래스의 상태 다이어그램에도 상속되는지, 하위 클래스의 행위는 상위 클래스의 행위를 제한시키는 것인지 확장시키는 것인지 등의 문제가 명확하지 않다. 또한 역할과 하위 클래스 설정 문제도 혼동이 일어난다. 본 논문에서는 Liskov의 치환 규칙에 의하여 정적인 면과 동적인 면을 동시에 고려한 상속성 원리를 OCL을 사용하여 정립한다. 이에 따라 역할, 일반화, 특수화, 집합체와 합성에 관한 개념의 가이드라인도 제시한다. There are no explicit rules in OOA/D to indicate whether or not the generalization and specialization hierarchy on a superclass is inherited by its subclasses. For example, we have relevant questions: ls a constraint on a suerclass is inherited by its subclasses? Does subclasses inherit the state diagram of the superclass? Can it refine this state diagram by adding. removing or redefining states, transitions, or events? Can it restrict the behavior of the generalization classes or extend it both? Many methods do not answer these questions. Also concepts of role and subclass are confused in the problem of structure. In this paper, we give an OCL formalization of inheritance by Liskov's Substitution Principle and propose a general guide-lines of concepts of role, generalization, specialization, aggregation, and composition.

6 pigs suddenly died of severe dyspnea at the piggery in Chungbuk and Daejeon, Korea. Authors diagnosed it as porcine pleuropneumonia resulting in A. pleuropneumoniae on the ground of pathological findings and bacteriological isolation. The clinical signs were high fever, depression, dyspnea, blood-tinged discharge through the mouth and nostrils, cough, sialism. In grossly, congestion and hemorrhage were showed in the acute pleuropneumonia in 4 pigs. In 2 pigs, the chronic pleuropnuemonia characterized by adhesion between visceral pleura and parietal pleura resulting in fibrous exudate was observed. The histopathologic changes were characterized by congestion, hemorrhage, neutrophil infiltration, edema, vascular thrombosis, macrophage activation, and fibrinous exudate in the acute pleuropneumonia. In the chronic stages of this disease, fibrous pleuritis, macrophage infiltration, lymphocyte infiltration, and marked fibrosis around areas of necrosis were observed. Also there were oat cells, the characters of porcine pleuropneumonia. Actinobacillus pleuropneumonia was isolated from pneumonic lesions and biochemical identification was carried out. A. pleuropneumoniae was particularly susceptible in vitro to Amoxicillin/clavulanic acid, Ampicillin, Ciprofloxacin. Norfloxacin, Gentamycin, Tiamulin, Cefazolin, Ceftiofur, and Colistin.

In order to evaluate the mutagenic effects of extractable indoor air pollutants (organic matters), we measured the mutagenic activities by sensitive microsuspension Ames test using new tester strains (YG 1024 and YG 1029). And additionally to evaluate the mutagenic effects on vital cell, we examined the frequencies of micronucleus appearing in lymphocytes from dye handling workers and controls. This study was conducted from Jan. to May, 1995. The extractable indoor air pollutants were collected by low volume air sampler in a general office room and 3 of dye handling factories. And the environment of general office room divided into 3 different groups according to the type of room heaters. To determine the frequencies of micronucleus appearing in lymphocytes, we sampled peripheral venous blood from 20 of dye handling workers and 20 of controls, and cultured, and then examined the lymphocytes. The results obtained were as follows: 1. The indirect mutagenic activities of extractable organic matters from suspended particulates collected in a general office room were higher than the direct one. 2. The strain YG 1024 was the most sensitive, and the increasing order of test strains that showed higher number of revertant were YG 1024, YG 1029, TA 100, TA 98. 3. In the general office room, the room using kerosene heater showed the highest mutagenecity, and the next was buthan gas heater, and non-heating room in order. 4. The mutagenic effects of suspended particulates in dye handling factories on the strain YG 1024 was 1.2 times higher than YG 1029. 5. The frequencies of micronucleus appearing in lymphocyte of the circulating blood of dye handling workers and the control were 5.65±2.97‰ and 4.65±0.97‰, respectively. And the difference was statistically significant.

'가치'의 공유와 '표현'의 공유 : 기업윤리담론의 비판적 고찰 A Critique of the Business Ethics Discourse

송지환 연세대학교 경영연구소 1997 연세경영연구 Vol.34 No.1

요약이 연구는 기업윤리담론에서 근본적인 가정으로 여겨지는 '가치 공유'의 인식을 비판적으로 성찰한다. 특히 기업문화주의가 옹호하는 가치 공유의 가정에 대한 회의에 기초하여, 단지 가치의 표현들만이 공유될 뿐이라는 논지가 전개된다. 이러한 입장은 기업이 표방하는 도덕성이 기업의 필요에 따라 특별한 방식으로 선정되는 '표현'의 순환을 통해 조직구성원들에 의해 조작적으로 專有될 수 있음을 시사한다. 이에 따라 강한 기업문화를 주창하는 기업들이 신경영 기법을 적용한 과정에서 발생하는 표현 공유의 문제점들을 지적한다. 아울러 이 연구에서는 조직구성원들의 윤리적 주관성이 도덕적 가치에의 진정한 헌신과 도덕적 표현의 조작화에 대한 경험 사이의 긴장 상태에서 양면 감정적 태도로 형성됨을 論한다. 결론적으로, 이 연구에서는 기업활동의 현장에서 진정한 도덕적 가치의 공유가 실천되어야 할 것을 역설한다.
