Background/Aims: This study was designed to evaluated the effects of electroacupuncture on the sphincter of Oddi (SO) motility in humans and to correlate the manometric findings with plasma cholecystokinin (CCK) levels. Methods: Eleven patients (M: F= 5: 6) who had various kinds of biliary disorders were enrolled. SO motility was monitored with a conventional low-compliant continuously perfused technique using ERCP (n=9) or percutaneous transhepatic cholangioscope (n=2). After baseline monitoring for phasic wave contractions of SO, electroacupuncture was applied at a specific acupoint, GB 34, in these 11 patients. A nonspecific acupoint 5 cm away from GB 34 was selected as a control. Manometric parameters of SO were also checked in 6 subjects during stimulation of the control acupoint. CCK plasma levels were measured during the time course of electroacupuncture stimulation. Result: All the manometric parameters including the basal pressure of SO, amplitude, frequency and duration of phasic wave contraction of SO were significantly decreased (p< 0.05) during electroacupuncture stimulation. The inhibition of SO contractility was accompanied by increased CCK plasma levels. After removal of electroacupuncture stimulation, restoration of amplitude and duration to basal condition were noted. A tendency towards the return of SO contractility was also observed in basal pressure and frequency. Stimulation of the control acupoint, however, did not affect the SO contractility and plasma CCK levels. Conclusions: Electroacupuncture stimulation of acupoint GB 34 showed reversible inhibition of SO contraction in humans. We speculate that the response of SO to electroacupuncture stimulation may be mediated by some neurohormonal mechanisms including CCK release.

영남대학교 의료원 치료방사선과에서 1988년 6월 15일에 위함 환자의 수술중 방사선치료를 시작한 이래 1992년 8월 30일까지 총 58예에서 시도하여 그중 53예에서 IORT를 실시하였으며, 정기적인 추적검사에서 한명의 국소개발 환자도 보고되지 않고 있다. 출혈(3예), 장관폐쇄(3예), 폐혈증(2예), 골수기능저차(1예)를 포함한 총 9예(17%)의 합병증이 보고되었고, 이중 6예(13%)가 사망하였다. IORT(1500cGy), 외부 방사선치료 (-4500cGy)와 강한 항암제를 병합치료 하였음에도 불구하고 주등(수술과 항암제 치료)의 25.2%, 김등(수술 불가능한 환자에서 항암제 투여)의 18%, 리등(수술)의 18.5%, Kraming등(IORT 2800-3500cGy)의 35.3%에 비해 낮은 합병증을 보여 IORT가 위암의 치료에 공헌할 수 있음을 시사하였다. 그러나 비교적 높은 치사율(11.3%)은 더욱 세심한 수술수기 및 수술 후 환자의 치료가 필요하며 외부 방사선치료와 항암제치료의 적절한 시기 조절 및 치료선량의 가감이 필요할 것으로 생각된다. Local control is the important prognostic factor in cancer treatment because local control decrease the relative risk of metastatic spread and increase distant metastasis free survival. IORT is the modality which could increase local control without increasing complication, combined with curative operation. Eventhough we could achieve significant deacreased local failure by IORT and curative resection, it should not be committed as a main treatment modality without proving acceptable complications. Therapeutic Radiology Department of Yeungnam University Medical Center have tried 58 IORT from June 15, 1988 and performed 53 IORT in patients with gastric cancer. No local failure had been reported including interstinal obstrution, hemorrhage, sepsis, and bone marrow depression. These complications could be comparable to Jo's 25.2% (chemotherapy + operation), Kim's 18% (chemotherapy only in inoperable patients), because our treatment regimen is consisted of IORT (1500cGy), external irradiation (--4500cGy) and extensive chemotherapy (FAM, 5FU + MMC, BACOP). Our data encouraged us to re-inforce further IORT in stomach cancer treatment.

The DMA(Dimethylamine) gas sensors were fabricated with the ZnO-based thin films grown by a RF magnetron sputtering method. We investigated the sensitivity and response time according to temperature variation and DMA gas concentration. The ZnO-based thin film sensors sputtered in oxygen atmosphere showed higher sensitivity than those sputtered in argon atmosphere. The ZnO-based thin film sensors doped with Al_(2)O_(3), In_(2)O_(3) and V_(2)O_(5) and sputtered in oxygen atmosphere showed the maximum sensitivity of 218(working temperature, 250 ℃, DMA gas, 160 ppm) and speedy response time. The ZnO-based thin film sensors doped with Al_(2)O_(3), In_(2)O_(3), TiO_(2) and V_(2)O_(5), sputtered in oxygen atmosphere and aged at 330 ℃ showed the maximum sensitivity of 156(working temperature, 250 ℃, DMA gas, 160 ppm).

通貨와 GNP間의 因果關係 檢證

金相漢,徐正敎 慶北大學校 1992 論文集 Vol.52 No.-

To construct economic models and analyze economic phenomena with them, it is extremely important to make sure the relationship between monetary aggregates and economic activities. The relationship between money and, espacially, GNP has been a focus of the extensive controversies in macroeconomics betwen Keynesians and Monetarists, and there have been lots of both theoretical and empirical works. This paper summarizes the literature on the causality analysis and applies the outcomes in the literature to examining the causality relationship between monetary aggregates (M_1, M_2, M_3, RB, and M_2A) and nominal GNP or its components in Korea. In the preparatory discussion for constructing the model, the following four aspects were focused on. First, each of the two variables (X_t and Y_t) has to take the normal probability distribution. That is, any of the variables has to take constant means and variances. Therefore, in the empirical analysis of this paper we used two types of filtering process : (l-kL)^2 and (l-L)·(l-kL). Second, the filter which is used in the controlled model (in which future-time lags are eliminated) and the noncontrolled model must be the same type of filtering process to eliminate the serial correlation between residuals. It should be the case because any influence on the causality relationship that can occur due to using a different filter should be eliminated. Third, there is a problem of choosing the optimum number of time periods (in the past and in the future) to be used as the explanatory varaibles in the regression equations. In this paper, we considered four quaters of the future, eight quarters of the past, and four quarters of the past from the base time. To make the analysis simple, the same number of time lags were used for an identical regression model. Fourth, the raw data used for estimating a regression equation, in principle, should not be seasonally adjusted. This should be the case for avoiding any spurious causality that can be obtained from a different method of seasonal adjustment. The three causality tests-Sims Test, Granger Test and GMD Test-have been used, and "six steps", unlike the existing test methods, in constructing model were used to improve the statistical significance. The test results strongly suggest that the nominal GNP (or the real GNP) unidirectionally causes monetary aggregates (espicially, M_1 and M_2) in Korea. This outcome raises some significant implications for monetary policy in Korea as follows. The monetary indicators that have so far beenused as the intermediate target of monetary policy should be reconsidered. Regarding the problem of choosing an intermediate target in monetary policy, we should not rely on the monetary indicators that are obtained by the simple-sum monetary aggretates, but on interest rates, or judgments based on overall considerations on various monetary and real variables and expectational behaviors of the private sector followed by flexible and comprehensive policy implimentations. Especially, in Korea where the real-name system of financial transactions is not established yet and so flows of funds are apt to be distorted, a reliable linkage mechanism between the financial sector and the real one is called for as a prerequisite for intermediate targets to be informative variables.

김성교 慶北大學校 齒科大學 1991 慶北齒大論文集 Vol.8 No.1

The purpose of this study was to evaluate the influence of acid etching on the bonding of a composite resin to a light-curing glass-ionomer. After 68 specimens of Vitrabond, a light-curing glass-ionomer were cured in acrylic resin blocks, the specimen surfaces were grinded with 320-grit silicone carbide papers. The specimens were divided into 4 groups, 1 control and 3 experimentals according to the etching period. While specimen surfaces were etched for 15, 30 or 60 seconds with 37% phosphoric acid in the experimental groups, those of the control group were not etched. Scotchbond/Silux, a composite resin was bonded to the treated glass-ionomer surfaces. After each specimen was stored in distilled water at 37℃ for 7 days, shear bond strength was measured. Surface state of each group and failure mode of each specimen were examined under a scanning electron microscope. Correlation between the shear bond strength and the adhesive failure rate was evaluated also. The results were as follows: Acid etching procedure did not increased bond strength, but decreased it. Many voids of 30㎛ in size were found in the unetched glass-ionomer specimens, the size of voids and exposed area of large particles were increased with increasing etching period and small particles of 0.5-0.8㎛ in size were lost. Failure mode of bonded specimens showed more than 50% of adhesive failure rate, and the rate was increased with etching period. There was negative correlation between the bond strength and the adhesive failure rate, but it was weak(r=-0.28). J. Kyungpook Nat. Univ. Sch. Dent. Vol.8, No.1, 1∼17, 1991.
