SnO2 films were deposited on Coming 7059 glass substrates by chemical vapor deposition (CVD) process. The effects of deposition temperature, deposition time, reactant gas flow rate on deposition rate and structure of SnO2 thin films deposit, have been studied. The formed phase of films was greatly affected by deposition temperature. At 300℃, amorphous phase was developed, whereas crystal phase began to appear at 350℃, and above 400℃ the SnO2 films of perfect tetragonal rutile phase has taken shaped. The grain size and growth of SnO2 films were increased with an increasing deposition temperature, deposition time and gas flow rate. In elevated deposition temperature (about 300 ∼520℃), deposition rate increased, and otherwise above 520℃ deposition rate slightly decreased. From the deposition rate and the change of structure, deposition mechanism was shown to be different between below and over 520℃.

In order to recognize map images automatically and make them in the form of Data Base, hierarchical classification and recognition of various information should be done. In this paper, a method with which map information can be efficiently extracted is proposed where map image is hierarchically classified by each component and those components are supplemented with the use of structural characteristics of each component. The proposed method extracts map information using mixed method among image structure analysis methods. First, character, block and road areas are classified hierarchically from the map image using bottom-up method, and by top-down method character and block areas are supplemented to be appropriate for recognition using structural characteristics of each component. For the evaluation of the algorithm, a map of 1:3,000 is used. It's been confirmed that each component can be efficiently extracted and extracted information make them in the form of Data Base have been confirmed recognition using neural network.

In this paper, a new image coding method is presented, which computes DCT coefficients approximately using multi-stage subdecomposition technique. The performance is confirmed through applying the proposed method to an image coding system. Through experiment using real LENA image, it shows less blocking effect and faster performance than the conventional DCT in the low bit-rate.

아드레날린 수용체 중개에 의한 Catecholamine의 Synaptosome을 통한 칼슘 이동의 조절

조성진,이정수,신용규,이광수 중앙대학교 의과대학 의과학연구소 1988 中央醫大誌 Vol.13 No.1

The presynaptic α-adrenoceptors medicate a negative feedback mechanism which leads to inhibition of neurotransmitter release probably by restricting the calcium available for the excitation-secretion coupling. It is reported that norepinephrine may shorten the duration of plateau phase in action potential by decreasing a voltage sensitive, slow inward calcium current and this action of norepinephrine is antagonized by α-adrenergic blocking agents. It is also suggested that there is a direct linkage between adrenoceptors and Na+-K+ ATPase. In the present study, therefore, effects of norepinephrine, dopamine an 5-hydroxytryptamine on the calcium uptake, Na+-Ca++ exchange and membrane potential in rat brain synaptosomes were investigated. The actions of neurotransmitters on the regulators for cellular calcium transport were also studied by investigation effects of catecholamines on synaptosomal Na+-k+ ATPase, Ca++ ATPase and Na+-Ca++ ATPase activities with or without adrenergic blocking agents. In the reaction mixture containing calcium without potassium, the addition of ATP induced the synaptosomal calcium uptake only slightly. The further addition of potassium is followed by a marked increase in calcium uptake with concomittent development of membrane depolarization. Amounts of calcium uptake were increased with increasing concentrations of potassium but decreased in the presence of extracellular sodium. Norepinephrine, dopamine and 5-hydroxytryptamine inhibited the potassium induced calcium uptake but had no effect on membrane potential. Na+-K+ ATPase, Mg++ ATPase and Ca++ ATPase activities were stimulated by these amines and stimulatory effects of catecholamines were antagonized by phentolamine and propranolol. Ouabain enhanced potassium induced calcium uptake but significantly inhibited Na+-K+ ATPase activity. Diltiazem and dibucaine effectively inhibited the depolarization induced calcium uptake, but had a variable effects on ATPase activities. Dibucaine significantly inhibited Ca++ ATPase. Among various agents tested, dibucaine alone was shown to slow down the development of membrane depolarization. Norepinephrine, dopamine and 5-hydroxytryptamine inhibited both the sodium dependent calcium efflux and Na+-Ca++ ATPase activity. The inactivation of Na+-CA++ ATPase by catecholamines was reversed by phentolamine and propranolol. These results suggest that there is a linkage between presynaptie adrenoceptors and regulatory apparatus for calcium transport across the synaptic membrane. Catecholamines appear to inhibit the calcium transport by the indirect effect on the ATPases, particulary Na+-K+ ATPase at plasma membrane which is mediated by adrenoceptors and also by possible action on the calcium conductance mechanism. On the other hand, adrenergic agonists may affect the Na+ dependent Ca++ efflux in synaptic membranes.
