고진공내의 데칸용매하에서 요오드화메틸이 피리딘 및 α-피콜린과의 착물형성에 관한 연구
김영철,임종완,김명자 漢陽大學校 環境科學硏究所 1992 環境科學論文集 Vol.13 No.-
고진공내의 데칸용매하에서 요오드화메틸의 용해도를 5, 15 25℃에서 피리딘과 α-피콜린이 존재할때와 존재하지 않을 때의 두 경우에 대하여 각각 측정하였다. 데칸용매내에 피리딘과 α-피콜린이 존재할 때 요오드화메틸의 용해도가 존재하지 않을 때 보다 더 크고 α-피콜린과 요오드화메틸과의 상호작용이 피리딘과의 상호작용보다 더 강하게 작용한다는 것을 알 수 있었다. 그리고 피리딘과 α-피콜린이 데칸용매내에 존재할 때 요오드화메틸과 피리딘 및 α-피콜린이 각각 불안정한 Complex를 형성한다고 생각되어 이 Complex를 여러 경우의 비율로 가정하여 게산해 본 결과 1 : 1Complex를 형성한다고 보는 경우의 평형상수 K 값이 비교적 일저한 값을 나타내었다. 그러므로 1 : 1Complex 즉 CH₃I·??과 CH₃I·α-??이 영액속에 형성됨을 알았다. 그리고 피리딘과 α-피콜린의 요오드화메틸과의 Complex의 안정도를 이와 대응하는 요오드화에틸과 요오드화 n-프로필과 비교하여 보았다. 또한 이 Complex의 생성에 대한 엔탈피, 자유에너지 및 엔트로피의 변화도 산출하였다. The solubilities of methyl iodide in decane on high vacuum were measured at 5℃, 15℃ and 25℃ in the presence and absence of pyridine and α-picoline. When pyridine and α-picoline exist in system respectively, the solubilities of methyl iodide in the presence of puridine and α-picoline are greater than in the absence, and the interaction of methyl ildide with α-picoline is stronger than with pyridine. In the presence of pyridine and α-picoline, it could be though that methyl iodide forms unstable complex with pyridine and picoline. The complex was assumed in various ways and it was evaluated that the equilibrium constant K value was relatively constant under the assumption of 1 : 1 complex. Thus, 1 : 1 complexes, CH₃I·C??H??N and CH₃I·α-C??H??N, are formed in the solution. And the stability of the complex of methyl iodide with pyridine and α-picoline are compared with similar complexes of pyridine and α-picoline with ethyl iodide and n-propyliodide. Also, the changes of enthalpy, free energy and entropy for the formation of the complex were calculated.

The purpose of this survey was to investigate health education level of women college students major in dance from health knowledge, health attitude and health behavior aspect, the questionnaire survey was carried out for 320 students of 4 universities of seven other areas respectively. Questionnaire contents covered smoking, drinking alcohol, irradiation by X-ray, cause of cancer, fatigue and necessity of physical examination. The result of the survey showed as follows; 1, 67% of total students responded with proper health knowledge. It showed that the health knowledge more higher level than health attitude and behavior aspects. 2. 54% of total students responded with right health attitude. It showed that the health attitude more higher level than behavior aspects. 3. 52% of total students responded with right behavior aspects. It showed that the behavior aspects smallest level than health knowledge and health attitude. 4. It appeared that inter-relation between health knowledge, attitude and behavior aspects showed a statistically significant difference (P<01).

Background: Recently the health insurance review agency tried to cut off the cost of unnecessary hospital stay. It is important to reduce the prolonged occupation of the hospital beds. However, there are some obstacles of the management for the prolonged bed occupation. We report our experiences and the problems of bed-control. Methods: To increase the rate of effective bed-usage, a task force was made. This team was consisted of 4 dctors, 2 nurses and 2 personnel of the administrative department. From December 20th 2001 to May 17th 2002, the task force analysed the rate, number and causes of the prolonged (more than 60 days, regardless of the disease entities) bed occupation. We announced and explained the necessity of bed-control and actively pressed to reduce the prolonged bed occupation. Results: The number of the prolonged bed occupation was 71 at the beginning of the management. It was reduced to 46 at best, then turned back to 65 at the end. It seems to be impossible to reduce the prolonged bed occupation until there are sufficient numbers of long-term care facilities. Aggressive bed control makes the sick patients to move every two or three months, it is never desirable. Conclusion: We cannot expect any Quality Improvements without improvement of the wrong system. Prior to the management for the prolonged bed occupation, it is necessary to build a sufficient number of long-term care facilities.

<P>Allergic rhinitis (AR) is an allergic inflammatory disease induced by various mediators released by infiltrating inflammatory cells. Vascular endothelial growth factor (VEGF) increases the airway inflammatory response by promoting vascular permeability. Furthermore, it is known that Allium hookeri and one of its constituent compounds, rutin (RU), have anti-inflammatory, antioxidant, and antiplatelet effects.</P>
Effect of Temperature on Persistence of Recombinant Plasmid pCU103 in Different Waters
Kwak, Myong-Ja,Kim, Chi-Kyung,Kim, Young-Chang,Lim, Jai-Yun,Kim, Young-Soo,Lee, Ki-Sung,Min, Kyung-Hee The Microbiological Society of Korea 1995 The journal of microbiology Vol.33 No.3
The recombinant plasmid of pCU103 constructed by cloning pcbCD genes in pBluescript SK(+) was studied for the effect of temperature on its persistence in different waters by the methods of electrophoresis, Southern hybridization, quantification, and transformation. The plasmid was very rapidly degraded out in non-sterile FW water without regards to water temperature, probably due to the effect of biochemical factor such as nucleases. The pCU103 was most persistent at 4$^{\circ}C$ in any water environments, moderately persistant at 15$^{\circ}C$ but least stable at 3$0^{\circ}C$ such results could be explained by the facts that hydrogen bonds in double-stranded plasmid DNAs become unstable and that nucleases are activated by increasing temperature. The intact structure of pCU1-3 was generally observed by gel electrophoresis under the conditions which the plasmid should be 2.0 ng/$\mu\textrm{l}$ or higher in concentration and that about 10$^2$ CFU/ml or more transformant cells should be recovered.
ICT 활용 교육 2 : 사이버가정학습에 대한 소외계층의 만족도 및 효과성 분석 연구

본 연구는 우리나라 초중등 이러닝의 대표 브랜드라 할 수 있는 사이버가정학습에 있어서 소외계층 학생들이 어느 정도 만족도를 나타내는지에 관심을 가지고 시작되었다. 사이버가정학습은 이러닝 활성화라는 교육적 패러다임의 변화에 힘입어 사교육을 감소시키고 공교육을 강화하고자 하는 목적을 가지고 있다. 특히 소외계층에 대한 지원 강화를 통하여 지역간o계층간 교육격차를 해소하고자 하였다. 이에 본 연구에서는 사이버가정학습을 하는 소외계층의 학생들과 일반학생들과의 만족도 및 효과성 비교를 통하여 소외계층 학생들의 사이버가정학습에 대한 만족도 및 효과성 수준이 어느 정도인지를 파악하고자 하였다.
