김성원 한국약제학회 1977 Journal of Pharmaceutical Investigation Vol.7 No.1

A study on the mechanism of biliary and urinary excretion of chloramphenicol has been performed in the dog. 1) Chloramphenicol administered intravenously to dogs with ligated renal pedicle, readily appeared in bile greater than in plasma. 6.9% of a 50㎎/㎏ i. v. dose of chloramphenicol were excreted into bile within 100 minutes. During the same periods of above experiment, the bile/plasma concentration ratios(B/P ratios) were 46 to 87. 2) Chloramphenicol injected into the vein of dog was rapidly excreted into urine. 18% of the administered dose were excreted into urine within 70 minutes. In the same periods of this experiment, Ccm/Ccr ratios were greater than 1.0 in most cases. 3) In experiment of simultaneous measurement of biliary and urinary excretion of chloramphenicol, Ccm/Ccr ratios were less than 1.0 and B/P ratios were 50 to 52. 4) In experiment measured simultaneously biliary and urinary excretion both Ccm/Ccr and C^HCm(hepatic clearance) were significantly declined by probenecid, but not affected by 2, 4-DNP and aminophylline although 2, 4-DNP increased only bile flow and aminophylline both bile and urine volume. 5) Ccm/Ccr and C^HCm were increased in proportion to increment of plasma concentration ranging from 3.3 to 30 ㎎% of chloramphenicol. But when plasma concentration were increased to 70㎎%, Ccm/Ccr were not increased and C_HCm were reduced about 30% in comparison with values obtained at 30㎎% of chloramphenicol. 6) Free/Bound(free to bouid from) ratios ranging from 1.0 to 90.0㎎% of chloramphenicol were 76.2+3.72% (mean±S.E.) Above results suggest that chloramphenicol is excreted into bile by a process of active trasport, that excretion of chloramphenicol into urine was made up with dual process, reabsorption and secretion, and that renal secretion was attained by active trasport process although renal reabsorption process could not understand.

우 누의 종교국가건설 노력과 좌절의 원인 : U Nu's Trying To Build A Religion State

김성원 釜山外國語大學校 1997 外大論叢 Vol.17 No.1

A great traditional trend shown in political culture of Myanmar is ‘Disruption’. The backgrounds of this trend are vertical breakdown between the ruling class and the ruled class and a level isolation or disruption tendency of various ethnic groups who have been living for so long in Myanmar. But Buddhism has been a very important role making people in Myanmar being one. So U Nu, the first Premier after independence, tried to build concrete State or Nation through Buddhism. Though the case of Myanmar provides illustrations of a wide spectrum of religio-political phenomena, we must consider “Can Buddhism provide the values needed to create a modern Myanmar national identity?”“Can religion, a vital source of political legitimacy for traditional Myanmar kingship, provide equally effective support for present day military regime?” In terms of these facts U Nu's government-sponsored revival of Buddhism must be examined. at least in part. So the purpose of this study is to illustrate the cause of U Nu's failure to try to build religion state in spite of Buddhism's traditional legitimacy and ration to be state ideologie in Myanmar. And the conclusion of his study is “U Nu's political failure is above all responsible for his political capability.” Because the burmese kings of old, U Nu's government made no attempt to purify the Buddhist religion of beliefs and practices deemed incompatible with orthodoxy. And U Nu mad little effort to adjust buddhism to the modern world, although this was obviously needed. Possibly he sensed the unity and cohesiveness of traditional ideas and values. Almost all he sought legitimacy for this political leadership by associating it with this unbroken network of tradition.

대구ㆍ경북 지역 유치원의 실태에 관한 연구 : 유치원 교육활동을 중심으로 giving importance to the educational activities in the kindergartens

金聖園 대구산업정보대학 1996 논문집 Vol.10 No.1

After 1980, there was a turning point in the arca of the kindergarten education. The kindergarten education that had been considered as the education for the childern of privileged classes has been popularized, and the insterest of parents in it has been increased. A lot of statutes ordain the contents of kindergarten education and facilities and teaching materials in the kindergartens. But actually there are its own contens and methods of education in each kindergarten on the basis of the statutes. For this study on the actual educational activities in the fields, a survey has been performed on the kindergartens in Taegu and Kyungbuk by interviews or mailing questionnaire. The questionnaire are composed of the questions about educational programs, making teaching programs, special educational activities, events in the kindergartens, and presentations about research activities and training for the teachers. As results, data on various activities and events have been obtained. In the case of the special educational activities, the number of the teachers majored in children education is larger than that of the instructors from the outside majored in the special activities as chargers. It seems that the positive attitude toward attending training programs and the activation of the training in the kindergarten are advisable for the improvement of education programs and contents.

As operating temperatures of engines or turbines continually increase for higher efficiency, significant amounts of researches have been focused on finding new materials, which would be alternatives to conventional yttria-stabilized zirconia (YSZ) for thermal barrier coatings (TBCs). In this study, phase evolution and thermo-physical properties of $La_2(Zr_{1-x}Hf_x)_2O_7$ pyrochlore systems are investigated for TBC applications. $La_2(Zr_{1-x}Hf_x)_2O_7$ systems are comprised by selecting $La^{3+}$ as A-site ions and $Zr^{4+}/Hf^{4+}$ as B-site ions in $A_2B_2O_7$ pyrochlore structures. For the developed phases in $La_2(Zr_{1-x}Hf_x)_2O_7$ compositions, thermo-physical properties such as thermal conductivity, thermal expansion coefficient are examined. The potential of these $La_2(Zr_{1-x}Hf_x)_2O_7$ compositions for TBC application is also discussed.

金聖園 대구산업정보대학 1992 논문집 Vol.6 No.-

Taishou-era that succeeded Meiji-era in which Absolutism had been established is very important in the Japanese Modern History. During Taishou-era, all the areas including politics, economy, and culture had been changed. In the area of education, 「Taishou Liberal Education Movement」 had been begun. 「Taishou Liberal Education」 had been affected by Taishou Democracy occured in Taishou-era and the ideas from foreign countries, and it had been developed with the elementary schools affiliated to the teacher's colleges and the private schools as the center. But it had started to decline as Taishu Democracy had declined because of mainly the suppression and the intereference of the Government. However, it has affected the education in the next ages and especially new study methods which had been tried in the area of education method largely affected the developments of the Japanese education.

The objective of this study is at the development of the channel routing model which can be used for flood prediction. Among the routing models, the hydraulic technique of the implicit scheme in the dynamic equation is selected to route the unsteady varied flow in the open channel. The channel routing model is catchment runoff which computed by the conceptual and transfer function model. The conceptual and transfer function model can simulate the catchment runoff accurately. As a result of investigating the channel routing model, the optimal weighting factor θ which fixes two points between time line is chosen. And also, the optimal error tolerance which satisfies computing time and converge of solution is determined in this study.

OFDMA 시스템의 ARQ 기반 멀티캐스트 방법

김성원,Kim, Sung-Won 한국정보통신학회 2009 한국정보통신학회논문지 Vol.13 No.1

한 노드에서 다수의 노드로 데이터를 전달하는 one-hop 통신에 사용되는 매체접속제어(MAC)는 멀티캐스트 기반의 데이터 통신을 사용하는 것이 매우 효율적이다. 유니캐스트와 달리 멀티캐스트에서는 모든 노드들과의 통신에서 우수한 품질을 얻기 위해서는 여러 노드들과의 서로 다른 무선 채널환경과 노드 이동성에 따른 무전 채널환경 변화에 대응할 수 있어야 한다. 하지만, IEEE 802.11에서는 다수개의 노드들과 RTS, CTS, ACK을 교환하는 방법이 정의되어 있지 않아서 신뢰성 있는 멀티캐스트를 지원하지 않고 있다. 이러한 문제를 해결하기 위해서 몇 가지 MAC 계층 프로토콜들이 제안되었다. 하지만, 신뢰성 있는 멀티 캐스트를 구현하기 위해서는 추가적인 오버헤드가 필요하며, 이 오버헤드로 인해서 시스템 성능이 저하하게 된다. 본 논문에서는 OFDMA 시스템에서 신뢰성 있는 멀티 캐스트를 구현하기 위해 필요한 오버헤드를 줄이기 위하여 계층통합적 (cross-layer) 설계기법을 제안한다. 제안된 오버헤드와 시스템 성능간의 관계를 분석하는 방법도 제안한다. Multicast-based data communication is an efficient communication scheme in wireless networks where the Media Access Control (MAC) layer is based on one-hop broadcast from one source to multiple receivers. Compared with unicast, multicast over wireless channel should handle varying channel conditions of multiple users and user mobility to achieve good quality for all users. However, IEEE 802.11 does not support reliable multicast due to its inability to exchange RTS/CTS and ACK with multiple recipients. Thus, several MAC layer protocols have been proposed to provide reliable multicast. For the reliable multicast, an additional overhead is introduced and it degrades the system performance. In this paper, we propose a cross-layer design to reduce the control overhead for reliable multicast in OFDMA systems. We present an analytical formulation of the system throughput associated with the overhead.

치밀화된 Ti(C,N)과 TiC-TiN-Ni 써멧에서의 Ti(C,N) 고용상의 특성평가

김성원,채정민,강신후,류성수,김형태,Kim, Seong-Won,Chae, Jung-Min,Kang, Shin-Hoo,Ryu, Sung-Soo,Kim, Hyung-Tae 한국분말야금학회 2008 한국분말재료학회지 (KPMI) Vol.15 No.6

Ti(C,N) solid solutions in hot-pressed Ti($C_{x}N_{1-x}$) (x=0.0, 0.3, 0.5, 0.7, 1.0) and 40TiC-40TiN-20Ni (in wt.%) cermet were characterized in this study. For hot-pressed Ti(C,N)s, the lattice parameters and hardness values of Ti(C,N) were determined by using XRD (X-Ray Diffraction) and nanoindentation. The properties of hot-pressed Ti(C,N) samples changed linearly with their carbon or nitrogen contents. For the TiC-TiN-Ni cermet, the hardness of the hard phase and binder phase were determined by nanoindentation in conjunction with microstructural observation. The measured hardness values were ${\sim}8.7$ GPa for the binder phase and ${\sim}28.7$ GPa for the hard phase, which was close to the hardness of hot-pressed Ti($C_{0.7}N_{0.3}$).

日本의 早敎育에 關한 一 考察

金聖園 대구산업정보대학 1994 논문집 Vol.8 No.-

Children education has attracted much attention for many years. Recently, early stage education has become popular for learning special skills in the area of music, art and physical activities. This early stage education means the education performed during childhood, while the advance education means that performed in advance thought it is normal to be performed later. But the education that belongs to the area of the advance education is usually treated as the early stage education. Among many opinions regarding various educations for improving one's talents during childhood, the time, the situation, the motive, and the actual condition has been researched for the case of Japan as an example. It is remarkable that various educations for the talent improvement are being performed in kindergartens and nurserys. It seems that children's interests above all are treated with importance for the establishment of education systems. Also it is thought with importance that the persons with professional knowledge should be engaged in the kinds of education.
