As the cytogenetic developed, cytogenetic study has also developed progressively. This study is a systematical cytogenetic and clinico-hormonal analysis of 20 cases Wp.ere gonadal dysgenesis was diagnosed and deferred to the Dept. of obstetrics and Gynecology, Yonsei University, Medical School from Jan. 1974 to Aug. 1983. Twenty patients with the diagnosis of gonada dysgenesis have been assesed as to possible correlations between clinical, homonal and cytogenic findings. The desults were as follows; l. Gonadal dysgenesis were found in 20 cases, consisting of 15 cases (75%) of turnurs syndrome, 4 case of pure gonadal dysgenesis (20%), 46. XX and 1 case of mixed gonadal dysgenesis, 45,XO/46,XY. 2. Patients with XO karyotype, turner's ryndorme, have a resonably constant clinical picture of sexual infantilism with streak gonads, short status and webbed neck. 3. 17 cases were found primary amenorhea and two cases were noted with 2 ndary amenorrhea. one case has been presented with menstruation. 4. The rudimentary streak gonads were found in 7 cases of 8 cases and one case has a rudimentary streak gonad on one side and a testis on the contralateral side. 5. The study showed that potients with gonadal dysgenesis had an average of about 4-8 times higher basal FSH and about 3-7 times higher basal LH than that of the early follicular phase of normal menstrual cycle. 6. Two cases of three gonadal dysgenesis patieats, who performed LH-RH challage test, showed that the serum FSH levels reached the maximal level at 30 min after injection of CHRH and the serum LH level reached the maximal level at 60 min ofter injection of LHRH one case showed no significant response to LH-RH injection. Thus, bu studying simultoneously the clinical, cytogenic, hormonal aspects and visualization of gonads, we have gained some practical insight into the requirements for proper disgnosis and treatment.

T his paper presents the lateral and longitudinal control algorithm for the driving of a 4WS AGV(Automated Guided Vehicle). The control law to the lateral and longitudinal control of the AGV includes adaptive agin tuning ability, that is the controller gain of the gravity compensated PD controller can be changed on a real-time. The gain tuning law is derived from the Lyapunov direct method using the output error of the reference model and the actual model, And to show the performance of the presented lateral and longitudinal control algorithm, we simulate toe nonlinear AGV equations of the motion by deriving the Newton-Euler Method, The read path is from quay yard area to docking position in loading yard area. The quay yard area is where the quay crane loads the container to the AGV and the docking position is where the container is transferred to the gantry crane. The road types are constructed in a straight line and J-turn. When driving the straight line, the driving velocity is 6㎧ and the J-turn is 3㎧.

공장 내에서 부적절한 배선 및 설치 등에 의하여 검사과정을 수행할 경우 noise나 오결선을 유발시키며, 이는 측정해야할 신호가 부적절한 동작을 발생시키거나 검사가 되어 출하 후에 하지 않아도 될 A/S 지원을 해야 하는 등의 추가 경비가 소요되는 문제까지도 야기시킬 수 있다. 이때, 사용자측에서 발생될 불만에 따른 회사 및 제품의 신뢰도 저하는 더 큰 문제가 아닐 수 없다. 본 개발에서는 GUI(Graphic User Interface) 환경과 통신기술을 접목하여 다양한 제품의 검사를 위한 시스템을 개발하고자 한다.

24 bulls aged 18-20 monthes, representing three cattle breeds, 8 Korean Native Cattle(KNC), 8 Holstein Friesian(H) and 8 Korean Native Cattle×Chrolais(KC) were taken to investigate carcass composition and meat quality. KNC were fatter than the other breeds inspite of lower slaughter weight. H had less body fat with higher bone ratio. but showed no significant difference in retail meat yield from KC. Meats from H were lower in shearforce both on cooked and roasted samples. KNC had finer muscle_ Fiber, higher intramusclar fat and lower collage content. The ratio of muscle fat to body fat of KNC was remarkablly higher than that of the other breeds, which predicted to be better marbled at the same level of body fat. Average palatability characteristics such as juiciness, tenderness and flavor were within acceptable ranges for all cattle breeds, however, meat from H seems to be better in all palatability characteristics.

Although enlargement of the liver occurs in many disease states, Massive hepatomegaly or "Giant Liver" occurs in relatively few disorders. The diseases cited by most authors as capable of producing massive hepatomegaly are: 1. Metastatic carcinoma 2. Amylo
