This study has been performed to investigate into the internal oxidation characteristics of steels containing various Ni content with respect to the added amount of air in nitrogen-propane atmosphere after gas carburizing for various times at 930℃. The results obtained from the experiment are as follows ; (1) Optical micrographs have shown that the internal oxidation is unlikely to occur in the gas atmosphere without air and that oxidized zone in the outer surface layer is formed in the gas atmosphere with air, revealing that the depth of oxidized zone increases with increasing the added amount of air, considerably more than 18% of air. (2) The formation of internally oxidized zone in the outer surface layer has been found to be inhibited as Ni content increases, i.e. the amount of alloying element increases. (3) The depth of oxidation has been measured to increase with almost linearly increasing gas carburizing time of up to 6 hours.

The Study has the purpose to find the model for establishing the sound ethic in economics of sports. The results can be summarized as following presentation. 1. Relationship between human and economics of sports should be established by new method and character of economics different from dimension of business which has maintained traditionally in common economical life. 2. Economics of sports should be approached by human, lawful and social movemental level than the classical ideology of capitalism which has pursuited only profits blindly. 3. It is considered that the sound ethic in economics of sports should be established by the ethical integration with potential values of sports and revelational functions of economics which can surmount a various of case of economical deviation in sport world.

Sports has three spheres which is different among life-long sport for developing amusement and physical fitness of human, elite sport for developing technique and specialization of sport, and professional sport for earning the money. But sports had tendency of changing front the ideal function of theirs to the devices of life and popular occupation in modern industrial society gradually. The traditional scholars, which advocated the differentiation between sport and work, insisted that sport should be different from work for livelihood in motivation and purpose of its activity. By the way Lu¨schen, K. Maniel, A. Guttmann and Neo-Marxist advocated the theory of combining work and sport to find five characteristics of work in mordern industrialized society-Achievement, Technology. Training. Commodity and Bureaucratizing-out of internal and manifest characteristics of sport. But the divert phenominon was found in labor market of sport to the contrast of general labor market, which must have proposed the attributes for conquesting their problems. The results can be summarized as following presentation. (1) Labor market of sport has induced to non-perpect competitive market and segmantation labor market because supply and demand of atheletes be not elastic. (2) Discrimination of income and wage in sex, race and items of sport was found in labor market of sport, which should be removed from by structural and political consideration. (3) It is considered that clauses of law should be executed equally to the principle of liberal competition because the law of sport such as non-antitrust act and reserve clause was one--sided beneficial to the producer of sport such as owner and promotor. (4) It is considered that social mobility of atheletes had profound limitation in the choice of new occupation and the life--long of sport activity. (5) It is considered that the ideal model in laborization of sport can be found according as the internal value of sport and the economical effect of labor should be accepted by both in order to conquest self-isolation and disability of human.

This study has been carried out to elucidate the Ostwald Ripening behavior of M?C? type complex carbide precipitated in 13.5% Cr steel during spheroidizing treatment at a range of 650℃ to 710℃ after standarding the initial particle size distribution. The results obtained from the experiment are as follows. 1. Average particle size measurements have shown that based on the results obtained from the relation between the log of average particle radius and the log of spheroidizing time for three different temperatures 650℃, 680℃ and 710℃ the radius of (Cr, Fe)?C? complex carbide is proportional to the cubic root of spheroidizing time. 2. It has been found from the measurements of average particle radius and the number of particles per unit area that the average value of activation energy is obtained to be 53.5Kcal/mole, which shows that the coarsening of complex carbide precipitates is governed by the interdiffusion mechanism of Fe, Cr and C atoms. 3. Complex carbide particle size distribution curves appears to approach the steady state distribution curve obtained for diffusion controlled mechanism and does not reach it within a spheroidizing time of 1800 hours. 4. X-ray diffraction analysis has shown that complex carbide precipitated during spheroidizing treatment is (Cr, Fe)?C? and that for the same spheroidizing time values for lattice parameter increase with increasing spheroidizing temperature.

Local heating transportation pipe has sensor and return lines to detect water- leakage. There are impulse and resistance comparison measurementtypes for a water-leakage detection. The impulse type shows large detection error within a measurement range. Since the resistance comparison type can find a comparative accurate single water-leakage point in the measurement range of heating pipe. it has used to detect water-leakages these days. However if the multi water-leakages are happened in the measurement range of trange of transportation pipe. the resistance comparison type shows a detection error point by the parallel resistance between a detection sensor line and ground. But the detection error will be minimized by the divided transportation pipe loops. In this research, it suggests the design of remote controlled detector which can divide a large pipe loop and a possible single water-leakage measurement process in each divided loops.

N₂O가스 분위기에서 실리콘 기판상에 직접 열산화한 oxynitride막과 10nm 및 19nm 열산화막을 재산화시킨 oxynitride막의 전기적 특성을 연구하였다. 게이트 산화막을 질화한 질산화막은 기존의 열산화막을 대체할 수 있는 유전체로서 촉망받고 있는 재료의 하나이다. 질화의 방식 가운데서, N₂O분위기에서의 열산화는 암모니아 질화에서 나타나는 수소 관련 전자트랩핑을 피할 수 있다. N₂O가스로 산화시킬 때, Si/SiO₂계면에서의 질소 축적(pile-up)이 관찰되었다. Si/SiO₂계면에서의 질소 축적은 산화율을 상당히 감소시키는 산화제 확산 장벽을 작용했다. 그리고 Si/SiO₂계면으로의 질소 도입은 계면에서의 막구조를 강화시켰을 뿐만 아니라 게이트 유전체의 질을 개선시켰다. 이 공정에 의해 형성된 oxynitride막은 Si/SiO₂계면에서의 질소 축적에 기인하여 막성장율이 쉽게 제어되었다. 본 논문에서, oxynitidation은 전기로에서 수행되었으며, oxynitride막의 특성은 AES분석, 성장율, C-V, I-V 및 절연파괴특성을 분석함으로서 조사되었다. Electricial characteristics of gate dielectircs formed by oxidation of bare and oxidized(10nm and 19nm oxide) silicon in nitrous oxide gas(N₂O) have been studied. Nitrogen incorporation into the gate oxide is one of the promising methods as a possible alternatives to thermal oxides. Among the methods of nitridation thermal oxidation in N₂O ambient is capable of avoiding the H-related electron trapping which shown in the NH₃nitridation. During the N₂O oxidation, nitrogen pile-up at Si/SiO₂interface is observed. Nitrogen pile-up at Si/SiO₂interface acted as a oxidant diffusion barrier that reduces the oxidation rate significantly. And the incorporation of nitrogen at Si/SiO₂interface not only strengthens oxynitride structure at the interface but improves the gate dielectric quality. Oxynitride films formed by this process control film growth rate easily due to nitrogen pile-up at Si/SiO₂interface. In this paper, the oxynitridation is performed by the conventional furnace and the properties of the oxynitride films haven been investigated by analyzing the AES(Auger Electron Spectroscopy), growth rate, C-V, I-V and breakdown characteristics.
