Human sparganosois was reported more than 100 cases in Korean population. However no case reported yet in Korea as a patient was infected by sparganum from other geographical area, such as Thailand. The case we are reported here is a 38 year-old Korean male who had been suffered from mass being a small, round and soft consistance in upper portion of his right thigh. The patients stated that he had an opportunity to eat living snake in Bangkok, Thailand during trip. As therapy praziquantel (75㎎/㎏/day) was given p.o. for 14 days, but in vain to cure. Following medical treatment, surgical exicision was performed to remove a alive, soft, whitish-milky, mobile and elongated sparganum. Serlogical test by micro-ELISA for sparganum-specific antibody revealed a high serum antibody level of absorbance 0.67 (positive criterion: absorbance 0.22).

유도선수의 체중조절 및 영양관리에 관한 연구

김의환,이명천 龍仁大學校 體育科學硏究所 1998 體育科學硏究論叢 Vol.8 No.1

The purpose of this study was to review and recognize of the weight control and dietary survey of judoists. The reviews of this study suggested that typical weight loss procedures practiced by intercollegiate judoists result in decrease in upper body strength, anaerobic power out put, anaerobic capacity, the lactate threshold, and aerobic power. It can be speculated that judo performance of individuals who practice typical judo hydration techniques will be deleteriously affected. Most of the reviews investigating the rapid regaining(rehydration and refeeding) after making weight showed that performance returns to pre-weight-loss levels despite the nutritional recovery being incomplete. There was a paucity of data concerning the effect of different strategies for nutritonal recovery after the weigh-in on reinstatement of the judoists physiology and performance. The interrelationships among resting metabolic rate, weight regain, and accretion of body fat in judoists were uncler. Also, it was not known whether the behavioral patterns a judoists acquires during participation in the sport have any impact on the nutritional status or chronic disease later in life. Many rule modifications continue to be proposed in an attemped to discourage the practice of weight cutting. These include certification of judoist's at a minimum judo weight, redistribution of weight classes, allowing two competitors for each weight class, making weight-in closer to a match, and allowing only athletes that and in a hydrated state to complete. In addition, the importance of adequate food and fluid intake and their subsequent impact on health and prformance has been emphasized. Limiting the use of the crash weight reduction methods would have positive impacrt on the sport. Future research on wrestling and judo should include investigations of factors associated with elite performance and fatigue. There is no sound evidence that the recommendations are effective in maintaining performance normal growth rate and lean body mass. In evaluating the weight loss performance relationship, biomechenical, and psychological factors should also be considered as a part of the performance measurement.

이명환,채수규,전문진 고려대학교 자연자원대학 1995 자연자원논집 Vol.35 No.2

AlIium속 식물인 마늘을 생것인 상태 및 이들을 통째로, 얇게 썰어서 또는 다져서 동결건조처리에 따른 allicin을 포함한 유용성분의 함량변화와 allinase의 효소활성을 측정한 결과는 다음과 같다. 1. 시료의 전처리 방법에 따른 allicin과 dially1 disulfide의 함량은 생 것인 상태, 통째로 및 얇게 썰어서 및 다져서 동결건조시킨 순으로 감소하는 경향을 나타내었으며, 다져서 동결건조시킬때 약 35.3%의 allicin감소를 나타내었다. 2. pyruvate 함량을 시료 중량대비로 측정한 결과 생것인 상태보다는 통째로, 얇게 썰어서 및 다져서 동결건조시킨 순으로 증가하는 경향을 나타내었다. 3. 마늘의 동결건조방법에 따른 allinase 활성을 측정한 결과, 생마늘의 allinase 비활성은 7.422units/mg protein이었으며, 통째로, 다져서 및 얇게 썰어서 동결건조시킨 순으로 감소하는 경향을 나타내었다. 4. 동결건조시간 경과에 따라서 마늘을 통째로, 다져서 및 얇게 썰어서 동결건조시킬때, 수분함량이 감소하고, allinase활성은 감소한 반면에 puruvate의 함량은 증가하였으며, thiosulfinate 함량은 시간경과에 따라서 감소하는 경향을 나타내었다. The purpose of this study is to investigate changes in the amount of useful compounds including and in the enzyme activities of alliinase as a result of freeze-drying treatment of garlic in whole, sliced or crushed state. The results obtained are as follows: 1. The amount of allicin and diallyl disulfide was decreased: the degree of decrease was in the order of raw, freeze-dried whole, freeze-dried sliced and freeze-dried crushed. Garlic showed 35.3% allicin decrease almost 100% when they were freeze-dried crushed 2. The amount of pyruvate was increased: the degree of increase was in the same order as above. 3. The activity of allinase was reduced as a result of freeze-drying treatment: the degree of reduction was in the order of whole, crushed and sliced. The activity of allinase in raw garlic was 7.422units/mg protein. 4. When garlic was freeze-dried as whole, crushed or sliced, the amount of water and the activity of allinase decreased while the amount of pyruvate increased as time passed. And the amount of thiosulfinate tends to decrease as time passed.

A Clinical assessment of the 25 patients with dilated cardiomyopathy who were admitted to the Department of Pediatrics, Keimyung University Dong San Hospital from January, 1982 to June, 1993 was performed. The result were as follows: 1) Among 25 patients with dilated cardiomyopathy. 8(32%) were younger than 1 year of age at the time of admission. 2) Adriamycin toxicity was the only encountered etiologic factor in 1 patient. 3) On admission, hepatomegaly and tachycardia were noted in almost all patients. 4) The Chest X-rays showed cardiomegalies in all 25 patients, pulmonary vein congestions in 15(60%) and pleural effusion in 2(8%). 5) The electrocardiography showed left ventricular hypertrophy in 72% and supraventricular tachycardia in 32%. 6) The echocardiographic examination showed left ventricular dilatations in all patients and left atrial dilatations in 20(80%). 7) Of 18 patients who had followed mean period of 2.9 years, 10 patients died within 9 months after the diagnosis.

It is useful of the integration of rule systems into DBMS. Because rule-based system supports a eminent inference and analysis power and relational DBMS manages efficiently large data supporting consistency and independency. In this paper, we compares and analyzes the three approach for the integration of rule system into DBMS. Also we design inference system for rule-based database system.

정역석,류명춘,오주환 경운대학교 산업기술연구소 2001 産業技術硏究論文誌 Vol.3 No.2(B)

In this paper we model each cell as a set of the triangle and present the handoff area using a subset of the triangle. So, handoff area can be presented depending on radius-division degree of a cell easily. we predict that a mobile station can go our or not the current cell depending on mobile station' speed, direction. We propose a calculation method of handoff rate and handoff call number using the mobile station' moving speed, direction.

Background : In recent years, gonorrhea has been panedemic and remains one of the most commom STDs in the world, especially in developing countries. Objective & Methods: For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results: In 1996, 139 strains of N. gonorrhoeae were isolated, among which 53(39.0%) were PPNG. Conclusion: Our results suggests that after a peak of 74.3% in 1993, the prevalence of PPNG in Seoul is gradually declining.
