Control of an electro-hydraulic servo-controlled winch system which has no distinct performance specifications is investigated in this paper. Because of the lack of the performance specification, the research is focused to finding effective parameters which give clear physical meanings for the behavior of the system. Two new parameters named "settling rotation angle" and "settling safety ratio" are proposed for the control of general winch system. The physical meanings of the two parameters are explained precisely. Performance specifications for the target winch system are derived by using the proposed two parameters and a controller is designed to meet the performance specifications. Simulation results show that the designed controller gives responses which can be accepted for the target winch system. The concepts of the new design parameters proposed in this paper can be applied to any kind of servo-controlled winch systems.

Shoot tip and node segments derived from cuttings of two grape cultivars (Aramon, Aligote) were cultured in vitro on full - and one half strength MS media supplemented with BA, NAA, and 2,4-D alone and in combination, and the growth was investigated. Full strength, shoot tip, and NAA enhanced the shoot growth. BA alone and/or in combination with NAA was favorable for shoot multiplication regardless of media strength and bud position. Varietal differences were recognized in callus formation in favor of Aramon, and all growth regu-lators, especially BA+ NAA+2,4-D, were effective for callus formation in Aramon. Bud position ef-fect was negligible but half stremgth media was more effective. In Aligote, 2,4-D was most effective for callus formation regardless of media strength.

經濟統合에 따른 貿易擴大效果의 實證的 硏究 : EC를 中心으로 focusing the EC

趙鮮雄,金重根 全北大學校 1996 論文集 Vol.42 No.-

The purpose of this study is to empirically examine economic integration and trade expansion effects focusing the EC. We estimate to see the level and time trend in the EC economic integration using the gravity model with yearly data from 1970 to 1994. The main result of the study is that the trend of empirical effects is similar to that of EC's actual trade flow in year and economic integration stage separately. Though the trade expansion effects are increased slightly in the fourth stage('86-'92) and fifth stage('93-'94) due to the Single European Act, the Completing the Internal Market did not contribute to largely increased intratrade in EC because of recession in the EC economy. In the standpoint of increased intra-trade in EC, these result suggest to be proceeded to recover in the EC economy.

To make guideline to the diagnosis and treatment and or the intracranial nodular lesions, the authors made a clinical analysis on 81 pediatric patients who had showed nodular lesions on brain CT scan at Severance Hospital from Mar. 1979 to Feb. 1989 and the results were summarized as follows. 1) The peak incidence of intracranial nodular lesions were found in the 2nd decade(61.7%). There was no sexual difference. 2) The most common clinical symptom was seizure(92.6%) and the predilection site was parietal area. The nodular enhancing type on brain CT scan showed not only the most common type but also the most favorable clinical course. 3) As the etiology of the intracranial nodular lesions, tuberculosis, paragonimiasis, cysticercosis, tumor(meningioma), and aspergillosis were confirmed or suspected, but tuberculosis was the most common. CSF routine examination, chest PA, PNS X-rays, skin test for paragonimiasis and tuberculosis, CSF ELISA test for cysticercosis and paragonimiasis should be routine as the diagnostic studies. 4) We made treatment principle for intracranial nodular lesions. In cases that initial brain CT can show low density or calcified density without contrast enhancement, we treat those patients with anticonvulsants and steroid with regular check-up. If the lesion increase in size or new enhancement develops on follow up CT scan, medications for the suspected etiology should be added. In cases that initial brain CT scan show enhancing lesions, treatment is started with anticonvulsants and medications for the etiology regular check up. If the lesion increase in size on follow up CT scan or seizure is uncontrolled, surgery should be considered.

This paper represents an improved ECG data reduction algorithm which is very useful for real time ECG analysis based-on microcomputer. In order to increase data reduction rate of Turning Point(TP), existing real time data reduction algorithm. The results obtained from the improved Modified Turning point(MTP) data reduction algorithm applied to three different pattern ECG signals. (1) The average data reduction rate of MTP algorithm is 67%, which is increased by 17% than that of TP algorithm. (2) The average percent rms difference(APRD) which is a normalized value that indicates the error between two signals is 9.4% for TP algorithm, while the APRD of MTP algorithm is 6.2% for MTP algorithm. It means that the PRD can be improved by 3.19. Therefore, it gives more excellent resolution than that of TP algorithm.
