The influence of reactant gas composition on the rate of the water gas shift reaction over an iron oxide chromirum oxide catalyst was studied. This method of analyzing experimental tests showed that the rate of initial reaction of the water gas shift reac tion had increased with increasing P_(H_2O), but that had decreased with increasing P_(CO_2). It was found that the mass tranfer affect the rate of the water gas shift reaction except catalyst system. And this experimental results showed that the rate of reaction had increased with increasing P_(CO_2) and P_(H_2O). At this experimental condition, the rate of initial reaction was established γ_0=kP_(CO_2) P_(H_2O)/1+K_(H_2O) P_(H_2O) and the reaction rate constant, K, 225(m㏖/g-cat. hr) and K_(H_2O) is 3.5(atm)^-1.

The study was performed to observe the effects of arthrography on the tissues of temporomandibular joint histopathologically. Among 17 rabbits(34 joints), 2(4 joints) were used as normal control group, others (30 joints) were experimentally arthrographed using 0.03 ml diatrizoate meglumine (Hypaque meglumine 60, Wintrop, U.S.A). The rabbits were sacrificed at 2-hour, 1-, 2-, 4- and 7-day after experiment and the tissues of temporomandibular joint were prepared according to the usual method for light microscopic examination. The results were as follows: 1. There were no changes of the fibrous connective tissues of the condylar fossa, the fibrous connective tissues and hyaline cartilages of the condyle, and the articular disk. 2. In 2-hour experimental group, the proliferation of the surface synovial membrane cells, the congestion and hemorrage of the vessels were observed. 3. In 1 and 2-day experimental group, minimal lymphocytes infiltration was observed with the proliferation of the surface synovial membrane cells, the congestion and hemorrage of the vessels. 4. In 4-day experimental group, the diminution of the proliferation of the surface synovial membrane cells was seen, but there was no vascular changes. 5. In 7-day experimental group, the tissues showed similar appearance to the normal control group.

Many companies are using EDI(Electronic Data Interchange) for the electronic transmission of documents and information to and from other companies. The appearance of Internet can enhance existing EDI systems. Existing EDI systems have several problems such as poor system interoperability and high expense of VAN. This paper proposes a new EDI system utilizing Internet to provide open communication environment by using XML(eXtensible Markup Language) and this applies it to the EDI service for Hospital Demand. XML is a mark-up language extending HTML which is a standard language for expression of WWW(World-wide web) pages. XML is more structural than HTML, thus it is more suitable for the repetitive tasks of EDI and for the maintenance of databases. XML can transmit EDI documents in the open communication environment of Internet and users can easily access the documents with web browsers. Therefore we can provide EDI services within more open environment and we can build an EDI system with lower expense.

This research has been Performed on the purpose to reveal the reaction order and to examine how temperature, mole ratio, activity energy and space velocity on the conversion in using Feerrite cata1yst to convert. CO-gas into CO_2. These catalyst were prepared by copreciption and characterized by means of X-rays diffraction and BET studies. The result of experiment on carbon-monoxide-gas conversion reaction reaction are as follows; a) the conversional reaction of carbon monoxide is the first order reaction. b) Reaction temperature was revealed as range from 553K to 573K. c) the mole ratio of carbon monoxide vs oxygen was showed with in the range of 1.34. d) The activity energy of stronger than of any others was revealed at copper ferrite catalyst.

29 Boy's High school Hockey teams took part in the 36th National Assortment Hockey Championship Series, the 74th national Athletic Meeting and '94 Springtime National man and women Hockey competition which were held in 1993. Investgating the number of shooting and success rate in 43 games, I came to conclusion as follows : 1) In whole shooting, the number of shots in the area D was 48.89%, in the area B was 27.91%, in the area C was 19.07%, in order of shootings (p<.10). Success rate of shooting was about 26% in each A, B and C area, and it was comparatively high. 2) In angle shooting, the area Ⅲ marked 62.78% which was the highest success rate.(P<.10). The area Ⅳ marked 20.37%, and the area Ⅱ 13.19%. The success rate of shooting in the area was Ⅱ, Ⅲ, Ⅳ 23.73%, 23.60%, 20.91% which suggests the balanced distribution. Especially the success rate of shooting in the area I was 50%. and it says that boldness in shooting is very necessary. 3) In many kinds of shootings, penalty corner shooting was 39.44%, assist by pass was 23.89%, loose ball was 14.63%(P< .50). The score of penalty corner shootings was 35.78% which marked the highest goals. In assist by pass, solo dribble, free hit and penalty corner except penalty stroke, the success rate of shooting was 23.75% on the average. 4) At the position of stick used in shooting, fore position was the highest frequeney in use. It was 91.1%(P< .01). One touch action shooting was 59.63% which marked the highest frequency in shooting(P< .05). The rate of score was 51.22%, but in the success rate of shooting, direct action shooting is higher 32.18% than that. 5) Hit and push shooting was 84.07% of the whole shootings. Push shooting was the best in the rate of score(P< .05). In the success rate of shooting, flick shooting(51.35%), was higher than push shooting (27.27%).

This essay treats the theoretical disputes over '4 Dan-7 Jong' theory in 'Ri-ki' philosophy between Lee Toigye (1501∼1570) and Ki Ko-bong (1527∼1572) The controversy begun in 1559 and continued for 7 years, can be devided into 3 periods in its development in content, the first of which, the theoretical developments of the two philosophers, has been treated here in their mutual comparisive aspects. Ki Ko-bong refuted Toigye's theory, and Toigye on his side refuted Kobong's refutation supporting his own theory. I here support Toigye on this point on several grounds. I go on thereafter to present the following problems of importance. (1) the Being, defined as 'Thin' in general, is devided into real and ideal Beings. (2) Everything is derived from, and explained by 'Thing', to which is applied Ri-ki logic, the logic which is plane-level logic, unlike the one which goes through contradiction to unification. (3) The method of philosophy is regarded as the way to the progressive realization of Goodness through introspection; the way includes nothing of the conversion from quantity to quality, but only the quantative development. (4) The principle on which to define good and bad is, here, 'Ju-Ri' (Ri as the main role), or 'Ju-Ki' (Ki as the main role), the theory of mutual appearance of Ri and Ki. (5) The problem of the systemic order of values (goodness). The five problems above are very important in establishing Toigye philosophy on a newer and richer ground.

The modelling of complex dynamic system is one of the most important subjects in engineering. A model is often too complicated to be used in real problems so approximation procedures are often used to achieve simpler models than the original one. The concepts of impulse energy approximation is introduced. The reduced model in obtained from the most significant pairs of alpha and beta parameters. There exists errors because from the most significant pairs of alpha and beta parameters. There exists errors because of the truncation. To overcome this problem an improved impulse energy technique is presented in the paper by appropriately selection alpha and beta parameters. There exists error because of the truncation. To overcome this problem an improved impulse energy technique is presented in paper by appropriately selecting alpha and beta parameters to retain more impulse response of the original system. This algorithm is programed using MATLAB language. A reduced-order model for the excitation system of power plants as an example study is considered This technique seems to be easy to perform and shows a good simulation results.
