This study was performed to determine the blood and blood chemical values on captured 16 raccoon dogs (Nyctereutes procyonoides). Hematological examination revealed that RBC, Hb, PCV, MCV, MCH and MCHC values were 7.9±0.8x10^(6)/㎕, 14.0±2 g/dl, 44.1±5.5 %, 56.9±3.8 fl, 18.0±1.4 pg and 31.9±2.9 g/dl. respectively, and also revealed that WBC, neutrophil, lymphocyte. eosinophil and monocyte values were 13.6±2.4x10^(3)/㎕, 8.9±2.1x10^(3)/㎕, 2.7±0.8x10^(3)/㎕, 1.1±0.5x10^(3)/㎕ and 1.0±0.4x10^(3)/㎕, respectively. Blood chemical examination showed that total protein, albumin, globulin and A/G ratio values were 7.9±0.9 g/dl, 3.0±0.3 g/dl, 4.8±0.7 g/dl and 0.6±0.1, respectively, and also showed that ALT, AST, BUN. Creatinine and glucose values were 95.8±57.8 1U/ℓ, 64.4±30.1 1U/ℓ, 20.8±5.4 ㎎/dl, 0.7±0.1 ㎎/dl and 58.5±19.1 ㎎/dl, respectively.

This paper derives a modeling of a wind turbine and generator. and presents a power control algorithm for a full pitch-controlled wind turbine system. The design of a controller. in general. is performed by linearizing the torque in the vicinity of a operating point assuming the tip speed ratio is constant. For power control. however. the tip speed ratio is no longer a constant. In this study. a reference pitch model is derived in terms of a wind speed. angular velocity. and pitch angle. which makes it possible to design a controller without linearizing the non-linear torque model of the blade. The validity of the algorithm is demonstrated with the results produced through sets of simulation.

광양컨테이너터미널의 경쟁력 향상을 위한 항만 마케팅 전략에 관한 연구

정건명,김규환 木浦海洋大學校 2000 論文集 Vol.8 No.1

The marketing for the ports which were considered as a matter of no importance in the past is now becoming a prominent figure for the ports management and operation as there is keen competition in the container ports domestically and internationally. This competition will be increasing as the countries of the world is trying to construct container port in their own territory because it would produce new employment and value added as well as making additional effects to develop the service industry and the manufacturing industry related to the ports. To activate and to try to attract domestic and foreign enterprises Kwang-Yang ports, there needs the overall and continuous marketing strategy to work on positive lines to distinguish their image about the project and to differentiate them from the domestic or the international competitors. Although Kwang-Yang ports has geopolitical advantage in comparison with any other ports, there must be efforts than other competitive ports' around the world to make Kwang-Yang ports as the center of the ports in the far east on the facilities, operating condition and quality of services. By SWOT, the systematic approach for marketing policy of Kwang-Yang port was made. The summery of marketing strategy in this thesis are as fallows; First, Kwang-Yang ports must be given to functional as the capital manufacturing region of new industrial area. Second, self-sufficient local economic bloc should be built up. Third, the function of Kwang-Yang port must be strengthen to be center of the circum-pan-Pacific trade. If the economic cooperation of North and South Korea would grow, and if restoration of broken railroad from Seoul to Sineuijoo and from Seoul to Wonsan which means the terminus of transcontinental railway from Asia to Europe would be made, the importance of Kwang-Yang ports would increase. Forth, urban areas related to concept of megalopolis should be developed, and overall consolidation and extensive expansion of net transportation should be completed. Kwang-Yang ports has to attain competitive superiority as a port of transhipment for the activation of it Especially, to specialize Kwang-Yang ports to be port of transhipment, the port sales should improve as a part of strategy to make Kwang-Yang port the capital harbor in 21st century.

Torque generated by the blade of a wind turbine is a non-linear function of the wind velocity, the angular velocity of the rotor and the pitch angle. Glauert's theory for propellers, though widley used, is not suited to simulate the performance under variable wind speed and pitch angle. Furthermore, the numerical iteration procedure of the theory districts the applicability of a real time control of the wind turbine. We suggest a new method of modeling the torque that can be used in a real time control. Based on Glauert's theory, the power coefficient curve is estimated. In the vicinity of the operating point on the curve, a linearized model is extracted in terms of the wind velocity, the angular velocity and the pitch angle. the usefulness of the model is demonstrated with the results produced by sets of experiments.

물을 전기분해하여 제조한 수소/산소 혼합가스의 특성에 관한 연구

물을 전기분해하여 제조한 수소/산소 혼합가스의 응폭특성과 연소특성에 관해 연구하였다. 자동차용 점화코일을 이용한 고압방전장치를 제작하였으며, 이를 이용하여 응폭실험을 행한 결과에 따르면 강력한 외부로의 폭발이 있고난 후 진공이 형성되면서 응폭현상이 일어남을 확인할 수 있었다. 그러나 응폭특성이 수소/산소 혼합가스만의 유일한 특성인가에 대해서는 현재 결론을 내리기에는 어려운 실정이다. 또한 텅스텐금속의 연소실험결과에 따르면 수소/산소 혼합가스나 산소-LPG가스 모두 텅스텐금속을 연소시킬 수 있으므로,실제로는 대기중의 산소와 텅스텐금속이 산화반응을 일으켜 텅스텐산화물이 형성됨에 따라 녹는점이 1400-1600℃로 낮아진 결과로 판단되지만 보다 정확한 결론을 내리기 위해서는 좀 더 많은 연구가 필요하다고 판단된다.

Interferenz - 그 개념과 독어 습득시 나타나는 Interferenz의 例

金建煥 建國大學校 人文科學硏究所 1988 인문과학논총 Vol.20 No.-

Untersuchungsgegenstand der voriegenden Arbeit ist die Bedeutung des Wortes "Interferenz' und deren Phanomene, mit denen der Koreaner beim Erlernen der deutschen Sprache in Beruhrung kommt. Die Ursachen der Fehlerbildung sind zwar different, der Kausalnexus liegt jedoch zweifelsohne in der Divergenz von Ausgangs-und Zielsprache. Das Wort 'Interferenz' bedeutet den storenden Einflu?? eines Sprachsystems auf ein anderes, der aus der Verwandtschaft und Verschiedenheit sprachlicher Strukturen resultiert und zu unangemessenem Transfer fuhrt. Interferenzen kunnen auf allen Gebieten der Sprache auftreten, d.h. auf phonologischem, morphologischem, syntaktischem und semantischem Gebiet. Die muttersprachlichen Gewohneiten werden unwillkurlich und unbewu??t auf das fremdsprachliche Verhalten ubertragen. Da die Interferenzfehler als negativer Transfer auf der Divergenz zweier Sprachstrukturen beruben, unterscheiden sie sich von paralinguistischen Fehlerquellen, wie z.B. Nachl??ssigkeit oder andere verhaltensbeeinflussende Faktoren der Lerner. Die Interferenzfehler treten meist systematisch und spontan auf. Die kontrastiven analysen koreanisch-Deutsch und Fehleranalysen beim Erlernen der deutschen Sprache durch Koreaner fuhrten zur Feststellung, da es sich bei den meisten Fehlern um Interferenzfehler handelt. Durch eine intensive Beschaftigung mit Interferenz-Phanomenen in Richtung auf postiven Transfer und Fehlerprophylaxis bleibt eine wissenschaftlich fundierte Sprachdidaktik fur den Deutschunterricht in Korea zu erhoffen.

Concept of space is one of endless discussion topics and research's targets until now a days from ancient time. Concept of space in architecture was well-known in late 19th century, and was used as a important principle. Many architects made architectural space from the basis of these concept of space, and made ideation space through window. This study is to interpret existence and possibility of such space called ideological cognitive space which is shown through window.
