Faujasite 제올라이트의 CO 흡착에 대한 양자화학적 연구
김종택,이종렬,박두선 한국화학공학회 1989 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.27 No.5
여러 가지 양이온이 교환된 faujasite type 제올라이트와 CO 분자간의 상호작용과 제올라이트의 전자구조를 교환된 양이온의 종류, 제올라이트 골격 내의 Si/Al의 비에 따라 양자화학적 방법의 하나인 CNDO/2 법을 사용하여 계산하였다. 제올라이트 골격 내의 전자밀도는 Si/Al의 비가 감소할수록 증가하였으며, T-O간의 결합차수는 Si/Al의 비가 감소함에 따라 전반적으로 감소하였다. 제올라이트에 교환되어 있는 양이온과 CO간의 상호작용은 양이온의 정전기적 장의 세기와 밀접한 관계가 있었으며, Be^(2+)>Mg^(2+)>Li^+>Ca^(2+)>Na^+>H^+의 순서이었다. 제올나이드에 CO가 흡착되면 CO의 C-O간 결합차수는 증가하였으며, 이것은 IR 결과와 좋은 상관관계를 나타내었다. The CNDO/2 method was used to investigate the electronic structure and the interaction of CO molecules with the exchanged cations in the zeolites which have various Si/Al ratios. The electron densities of zeolites increased and the bond orders of T-O generally decreased with decreasing the Si/Al ratio. The strength of bond between CO molecules and the exchanged cations in the zeolites increased in the following order:H^+<Na^+<Ca^(2+)<Li^+<Mg^(2+)<Be^(2+). The interaction strength increased obviously with the electrostatic field of cations. The C-O bond orders of CO molecules interacting with the exchanged cations in the zeolites increased compared to those of free CO molecule. This was in a good agreement with IR results.

A one-month old Holstein calf with clinical histories of diarrheal weekness and behavioural abnormality revealed clinical findings of anemia and dehydration. The red blood cells were $1.4{\times} 10^{6}/{\mu}l$ and packed red cell volume was 45%. A blood smear showed a large number of circulating Trypanosoma theileri. To treat Trypanosomiasisi the patient received once a daily oral dosage o$\ulcorner$ 10 mg/kg of the Quinidine sulfate including transfusion (200 ml) for 3 days. After 2 weeks, the calf recovered body condition. These results suggest that Administration of Quinidine sulfate in trypanosomiasis may be a useful treatment approach.

Computer Simulation based of divided element method was done to predict strip shape in20-high Sendzimir Mill and has been used to find a way for preventing quarter waves occurring in the wide and thin gaged strip rolling. The simulation showed that it was difficult to prevent quarter waves by the existing methods of controlling actuators such as the shifting of the first intermediate roll and the profile control of As-U-Roll in back up roll. It was, however, confirmed analytically and experimentally that quarter waves could be effectively reduce by changing taper mode at the barrel-end taper radius of the first intermediate roll. 본 연구에서는 보강롤의 굽힘변형을 고려한 젠지미어 압연기의 롤변형 해석을 통해, 궈터웨이브의 발생을 시뮬레이션하고, 형상제어 수단들의 궈터웨이브 억제에 미 치는 영향을 분석하여 궈터웨이브 감소 방안을 수립하였고, 실제 현장 압연실험을 통 해 그 제어효과를 확인하였다.

호텔마케팅커뮤니케이션의 광고와 판매촉진이 고객만족과 추천의도와의 영향관계
김종택,김석영 동북아관광학회 2010 동북아관광연구 Vol.6 No.1
본 연구는 호텔 마케팅커뮤니케이션의 요인 중에서 광고와 판매촉진이 고객만족과 추천의도에 영향관계를 검증하기 위해 연구 되었다. 이를 위해 이론적 배경으로 선행연구들을 검토하여 연구문제의 해결을 위한 가설을 설정하였으며, 이를 실증적으로 분석하였다. 통계 분석은 SPSS(Ver. 12.0) 통계 프로그램을 이용하여 빈도분석, 요인분석, 신뢰도분석을 실시하였고, 가설을 검증하기 위해서 다중회귀분석을 실시하였다. 연구의 결과, 첫째로 호텔 마케팅커뮤니케이션의 요인 중에서 광고와 판매촉진이 고객만족에 영향을 미쳤다. 둘째, 호텔 마케팅커뮤니케이션의 요인 중에서 광고와 판매촉진이 추천의도에 영향을 미쳤다. 셋째, 고객만족이 추천의도에 영향을 미쳤다. 연구결과를 통하여 호텔경영에 있어서 광고와 판매촉진과 관련하여 관심을 기울려 서비스를 제공해야 하겠고, 고객만족과 주변사람들에게 적극적으로 구전할 수 있도록 하고 서비스와 판매촉진기술 광고를 병행하여 추천의도를 높일 수 있도록 해야 하겠다.

A 14-year-old virgin, female Yorkshire Terrier showed enlarged abdomen after udderectomy was diagnosed with canine mammary gland tumor accompanied with hydrometra. Gross findings appeared a white-yellowish $l0{\times}7{\times}7cm sized solid mass containing cysts filled with various colored mucoid fluids in the udder. Both uteri were distended greatly with white-yellowish watery fluids and their serosal surfaces were translucent. Characteristic micyoscopic findings in the mass of the udder showed great expansion of the mammary lobule and stroma and complete replacement of the glandular elements by prolifaration of myoepithelial cells. The mucosa of the uterus showed severe atrophy of the uterine epithelium.

金宗澤 慶北大學校 東洋文化硏究所 1983 東洋文化硏究 Vol.10 No.-
Expressional structures of modern Korean were compared with those of medieval Korean in this paper. Most materials which are available nowadays are versions of translated literatures from Chinese, consequently it is not surprising to find the massive influence from the source language. Because the two tongues are quite different in their grammatical structures and in their origins, no loaning nor influence were given from chinese in grammatical aspect, despite the large amount of interference. But medieval Korean had greatly influenced in the aspect of expressional structure, because the latter tongue was free in word order to some extent. As a result, we can infer that there were considerable difference between written language and spoken tongue in those days. Each of the following items are considered to be influenced from Chinese to written language in medieval Korean; a) There were many instances that predicate preceds object. (Modern Korean has converse word order.) b) Pro-verb(hata) was used freguently as a result of many quotations. c) Causative and passive constructions are used in the same form as Chinese. d) Quantifiers and Negatives are apt to precede their Heads. (i.e.; Quantifier + Noun phrase; Negative + Verb phrase) e) Other influences were found, for example in the position of Interrogative, in expression of person and thing and in expression of (pragmatic) distence.

意味構造의 普遍性에 關한 硏究 : 時調·絶句·Sonnet의 對照를 통하여 by a contrast of shijo, jeolgwi and sonnet
金宗澤 대구교육대학교 1971 論文集 Vol.7 No.-
"Shijo" is a peculiar set-form verse of Korea. Despite the difference of the cultural surroundings, Korean "Shijo"(時調), Chinese "Jeolgwi"(絶句) and sonnet have the same meaning structures. This identity of meaning structures does not lie in the influence and imitation relation with each other, but based on the universality of human expressional structures. From this point of view, "Shijo" is a peculiar set-form verse which Korean has developed.
