The nonlinear signals from an impedance meter for the area average void fraction in two-phase flow have been analyzed to construct a phase space trajectory. The pseudo phase space was constructed with the time delay and proper dimensions. The time delay and the embedding dimension were chosen by the average mutual information and by the false nearest neighborhood, respectively. The attractor-density-map of projected states was used to produce the two dimensional probability distribution functions (2D-PDF). Since the developed 2D-PDF showed clear distinction of the flow patterns, the flow regime identification was made with three rules and with the 2D-PDF. Also, the transition criteria of Mishima-Ishii agree well with the present results.

본 논문에서는 텍스처 매핑을 처리하기 위한 텍스처 유닛 하드웨어 설계에 효율적인 새로운 유동형 소수점 포맷을 제안한다. 기존 고정 소수점 포맷은 하드웨어가 간단한 반면 고품질 텍스처 처리를 수행할 경우 오버플로우/언더플로우가 발생하며 부동 소수점 포맷은 이를 해결할 수 있으나 하드웨어가 복잡하다. 제안한 방식은 오버플로우/언더플로우를 해결하면서 부동소수점보다 하드웨어 크기를 줄여서 본 포맷을 적용한 가산기는 부동소수점보다 26% 작으며 곱셈기는 고정/부동 소수점보다 절반 이상으로 작다. 따라서 제안한 포맷은 100Mhz 이상의 빠른 동작이 가능하며 모바일 3차원 그래픽 가속기의 텍스처 유닛 설계에 효과적이다.

This paper reviews the Insaenggeukjang's history and Insaenggeukjang's play. This paper has been written with a purpose to understand and to examine the members(actors and actresses), the structure, the plays, the performing works, the change process, and the meaning of Insaenggeukjang(life theater) and junggangeug(middle-theater) in 1930s. Insaenggeukjang is Korean theater for the drama in the second half of 1930s. In particular, Insaenggeukjang is a theatrical troupe that led Korean theatrical troupes in 1937 to 1938. This paper intend to examine Insaenggeukjang's history, activity, feature and works. I study Insaenggeukjang and performing works contained in the newspapers and the magazines in 1920-30s, and conference papers and theater-art books published recently.

배구자는 1920~30년대 조선에서 큰 인기를 확보한 무용수이자 연극인이었다. 그녀는 배구자악극단을 창립하여 조선과 해외(일본)를 오가면서 공연을 펼쳤고, 대중들은 그녀의 작품을 보기 위해서 극장으로 몰려들었다. 그녀와 그녀의 극단이 인기를 확보하고 있을 무렵, 그러니까 1931년 배구자무용연구소는 '혁신 공연'을 선언하고 일련의 작품을 발표했다. 당시 공연 작품 중에는 가무극 <파계>가 포함되어 있었는데, 다행히 <파계>는 공연 대본으로 기록되어 현재까지 전해질 수 있었다. 남아 있는 가무극 <파계>를 통해, 배구자무용연구소(나아가서는 '배구자악극단')의 공연 전략과 레퍼토리의 실체를 파악할 수 있을 것으로 기대된다. 조선 근대연극(사)의 주요한 축을 담당한 배구자악극단에 대한 연구는, 일제강점기 조선의 대중극의 다양한 갈래와 그 특성에 대한 이해를 제고할 것으로 전망된다.

Oil hydraulic piston pumps are being extensively used in the world, because of simple design, light weight and effective cost etc. An oil hydraulic pump is likely to have serious problems of high leakage, friction and low energy efficiency according to large time use. In the oil hydraulic piston pumps the clearance between the valve block and piston plays an important role for volumetric and overall efficiency. In this paper, the wear property of the SACM645 material used the hydraulic piston pump has been work out by experimentation with variable heat treatment. To investigate the effect according to the piston surface condition, seven different types specimen were prepared. From the wear test results, induction hardening and nitration were definitely superior to the others. On the whole, nitration was estimated for high strength material to wear resistance.

The purpose of this research was to investigate the immunoregulatory effect and the leukemia cell apoptosis of EtOH extract of OGAPI(OGP). The proliferation of cultured splenocytes, thymocytes and mesenteric lymph node cells were enhanced by the addition of OGP. Splenic and thymic T lymphocytes, especially TH and Tc cells were significantly increased in OGP-administered mice. OGP markedly increased the production of γ-interferon in mice serum and accelerated the phagocytic activity in peritoneal macrophages. OGP treatment enhanced the apoptosis of L1210 mouse leukemia and Jurkat, Molt4 human leukemia cells, and increased the expression of apoptosis-related ICE, c-myc, p53 gene in Jurkat cell. These results suggest that OGP have an immunoregulatory action and anti-cancer activity.

Emulsion polymerization ws carried out using Alkyl methacrylate(RMA) like MMA, EMA, BMA and Styrene Monomer(SM) for core-shell latex preparation. It was synthesized at $80^{\circ}C$ in the presence of anionic surfactant SLS(Sodium Lauryl Sulfate). FT-IR and DSC analysis are used to confirm the synthesized core-shell emulsion latexes. Moreover DSC and TGA were used to investigate the thermal characterisitcs of them. The differences of the decomposition rate and the activation energy from TGA and DSC analysis are not so big. It considers that the pendent group is not affect of the thermal characteristics and stability on core-shell latexes, which is synthesized with RMA and Styrene. For investigating combustion products, LC50 values were calculated by FED(Fractional Effective Dose)from the Pyrolyzer-Mass sepctrometer.

The colony education policy of Japanese Empire was, as a su n.0, ppression on national salvation education of Korean, on the one hand it was liquidation of Korean national spirit and other hand, it has the object to Japanizing Koreans through cramming Japanese language and its culture. During the Japanse occupation of Korea, the libraries had two roles, one was to press Korean and its culture and the other was to civilize Koreans for Japanizing. The purpose of this study is to examine the role of rural-mini libraries whether the former or the latter. From 1932 to The Chosun Governor- General Department (Chosun Chongdokboo) actively spread 'The Movement of Rural Development in Korea. At the same time there were many rural -mini libraries in Korean rural and fishing community. Under the colony of Japanese Empire, colony policy was itself very tough that Japanese Empire did their utmost ideas to win Korean culture over and Japanzing Korean with every possible pressures. Since rural-mini libraries were planned by the chosun Governor-General Department, however, were established by Korean themselves with the property of local education center( Hyanggyo). Therefore, rural-mini libraries were as facilities to promote rural economic development for providing Japanese with some materials which need to conduct a war, and to introduce local people to participate in civilizing activity themselves and farmers and fishermen were forced to group to be educated in Japanese language and its reading. Rural-mini libraries were, as it were, not as facilities for enlightening Korean peoples but as facilities for civilizing Koreans.

Copolymerization of ${\alpha}$-Methylstyrene(AMS) with Acrylonitrile(AN) was carried out with benzoylperoxide(BPO) as an initiator in toluene at $80^{\circ}C$ in a continuous stirred tank reactor. Reaction volume and residence time were 0.6 liters and 3 hours, respectively. The monomer reactivity ratios, $r_{AMS}$ and $r_{AN}$ determined by both the Kele$T{\"{u}}d\"{o}s$ method and the Fineman-Ross method were $r_{AMS}$=0.16(0.14), $r_{AN}$=0.04(0.06). The cross-termination factor ${\Phi}$ of the copolymer over the entire AMS composition ranged from 0.75 to 0.92. The ${\Phi}$ factors of poly(AMS-co-AN) were increased with increasing AMS content. The simulated conversions and copolymerization rates were compared with the experimental results. It was observed that the average time to reach dynamic steady-state was three times the residence time.
