This study investigated the time-dependent dimensional changes of elastomeric impression materials using holographic interferometry. Six commercial impression materials, Permlastic(polysulfide), Xantopren VI, (condensation silicone), low and medium viscosity of Exafine, Provil (addition silicone), and Impregum( polyether), were selected. Steel plate was used as custom tray, and each impression specimen was 20 mm in width, 15 mm in length and 3 mm in thickness. Each impression material was evaluated at 30 minutes, 1, 2 4, 6, 8 and 12 hours after setting using real-time holography. The results were as follow 1. Xantopren VL and Permlastic showed relatively severe and continuous dimensional changes after setting. Low viscosity of Exafine, Provil, Impregum showed relatively slight dimensional changes with function of time and medium viscosity of Exafine showed almost no dimensional change from 2 hours after setting to 6 hours. 2. On initial dimensional changes within 1 hour, the amount of change in low viscosity of Exafine was the least and Xantopren VL was the largest. 3. On dimensional changes at 4 hours after setting, the amount 'of change in medium viscosity of Exafine was the least and the change of Xantopren VL was the largest. 4. In overall dimensional stability during 12 hours, medium viscosity of Exafine was the most stable and Xantopren VL and Permlastic were least stable.

Procaine Amide及 Quinidine이 數種實驗的 不整脈에 미치는 效果에 對한 比

閔祗植 中央醫學社 1962 中央醫學 Vol.3 No.2

The antiarrhythmic and arrhythmytogenic effects of quinidine and procaine amide were investigated on the artificially produced arrhythmias in the whole rabbit and rat. Both quinidine and procaine amide could protect the rabbit from developing suba?rial thythms by the coaction of vagal stimulation and sympathomimetic amine: l-norepinephrine, l-eponephrine or isoproterenol. The comparison of the potency of these amines to produce ectopc beats during vagalstimulation by the smallest dose of each amine revealed isoproterenol to be much more potent than the others, as shown in other species. In the rabbit, quinidine seemed to potentiate the arrhythmytogenic effect of the intravenous aconitine, Whereas procaine amide lessened those of aconitine in some cases. The bradycardia developed by intravenous serotonin in the rat was almost ablished by the pretreament of procaine amide, but quinidine- pretreatment made the serotonin bradycardia more pronounced and prolonged.

This Study is Purposed to search Scientific management and human relations as main theories of human management in organization and estabilish the stratesies of systems approach. Scientific management implies a rational-economic man. The doctrine of rational-economic man Classified human beings into two groups-the untrustworty, money-motived, calculative mass and the trustworthy, more broadly motivated, moral elite who must organige and mange the mass Scientific mangement implies essentially acalculative involement human relations approach is Suchas followings man is basically motivated by social needs and obtains his basic Sense of identify through relationships With others and more responsive to Social forces of the peer group than to the incentives and Controls of management. The manager instead of being the creator of Work, the motivator, and the Controller becomes the facilitator and Symphathetic Supporter Systems approach is presented the doctrine of Complex-man, man is more complex individual than rational-economic, Social, or self-auctualiging man Not only is he more complex with in himself, heing Possessed of many needs and Potenitals but he is also libkely to differ form his neighbor in the patterns of his own Complexity. The sucessful manger in systems approach must be a good diagnostician and must value a spirt of inguiry. Finally he must have the personal flex ibility and the range of skills necessary to vary his own behavior.

企業公開論 : 5·29措置를 中心으로 relative to the 5·29 executive measures in particular

金址郁 건국대학교 1974 樂圓誌 Vol.9 No.1

In view of the fact that the corporations of our country are now being compeled to disclose themselves to the public, the writer tried to define the meaning of disclosure of corporations as being disclosure of accounts along with dispersing or disclosing their stocks to the public. I emphasized that the disclosure of accounts would contribute to protecting the interested parties around the corporations and simultaneously expediting the rationalization of management through the introduction of external audit system. On the other hand, I suggested that through dispersing the stocks of close corporations to the general investors and also financing themselves directly from the stock investors instead of private money lenders, they could not only attain their object of rationalizing their management but also enlarge themselves. I urged, however, that this problem should be solved by the disclosure of accounts prior to the dispersing of stocks and that the disclosure of accounts must be done step by step and not in a hurry from the view point of Korean economic stage. As for the dispersing of stocks, I foresee that it would be achieved by the development of the stock market where stocks will be transacted smoothly under the adequate appraisals of the general investors for the stocks. Thus, I appreciate very highly the current 5.29 executive measures as being a most reasonable policy which will expedite a long stride development of Korean enterprise. However, I consider that it would be more advisable to adopt the method of step-by-step rather than that of a hurry. By C.W.Kim

3 차 의료기관을 내원한 서부 경남지역의 표재성 피부 진균증 환자에 대한 임상적 및 균학적 인구학적 특성별 분포

Linear short fibers are added between laminae in a composite laminate to improve the interlaminar fracture toughness. The interlaminar fracture resistance is determined in terms of fracture energy utilizing the generalized locus method which can evaluate the fracture energy even in highly non-linear materials. The fracture energy of the short fiber reinforced specimens is increased about 20%. From the fracture surface study, it is show that the short fibers added at the interface disturb the progress of the fiber branching between the laminae during the fracture. This interruption behavior of the short fiber is thought to be the main cause of the improvement of the fracture energy.
