4-비닐피리딘계 이온 교환수지의 합성 및 그의 이온 교환능에 대한 연구
박병관,한동설 木浦大學校基礎科學硏究所 1984 基礎科學硏究誌 Vol.2 No.-
The ion exchangers such as 4-vinylpyridine-vinylacetate-divinylbenzene, 4-vinylpyridine-vinylalcohol-divinylbenzene and 4-vinylpyridine-vinylphosphate-divinylbenzene were prepared and the compositions of the above ion exchangers were confirmed by their infrared absorption spectra. The ion exchange capacities of the ion exchangers were examined and the adsorption properties of metal ion for them were also investigated. The ion exchange capacities of 4-VPVADVB, 4-VPVALDVB and 4-VPVPDVB were 1.8meq/g, 2.5meq/g and 4.1meq/g respectively.

This study is designed to grasp the elements and situations of stage fright in order to propose a part of ways to cope with it. We make 511 top-class high school players, male and female, in the central districts (Seoul, Inchon, Kyungki, Chungbuk, and Kangweon Province) on object of questionnaire, and get the following results. Through players generally have all-round characters they show weakness in the superiority and emotional stability while showing strength in the sonformity. This fact comes to be related to the elements which cause stage fright. Physiological changes also have many effects on the symptom of stage fright. Especially, stage fright increases when players show sensitive reaction to the self-consciousness of final consequence which comes from the tension or uneasiness of sympathetic nerve, Thus, it turns out that players make use of reducing psychological burden by physical exercise or adjusting the level of demanded result in order to release the stage fright.

We have used molecular biology technique to label the side chains and backbone of HBV preS1(1-56) with stable isotope (??) during E. coli over-expression and purified the protein to near homogeneity. The expression level of ?? labelled preS1(1-56) seems to be ∼15% of the total protein. to characterize the secondary structure of the labelled protein, circular dichroism was used. In different buffer conditions including pH 3.3 and pH 7.4 the protein seems to be devoid of any stable secondary structure probably suggesting that the N-terminal portion (preS1(1-56)) of HBV preS1 might be unstructured before binding to its target cells.
藥鍼이 Freund's Complete Adjuvant와 Peptidoglycan Polysaccharide에 의해서 誘發된 白鼠의 關節炎에 미치는 영향
李秉澈,한명관,羅昌洙 圓光大學校 韓醫學硏究所 1997 원광한의학 Vol.7 No.1
最近에 藥鍼療法이 많은 관심을 끌고 있다. 독특한 潤氣·六元의 原理에 依據하여 生體의 機能을 調整하고 病理狀態를 改變시켜, 疾病을 治療하는 新鍼療法중 하나이다. 이런 藥鍼療法은 매우 多樣한 疾患에 應用되고 있는데, 關節炎 治療에도 適用되고 있다. 牛黃·熊膽 藥鍼과 牛黃·猪膽 藥鍼의 效果를 比較 檢討하기 위하여 Freund's complete adjuvant와 peptidoglycan polysaccharide를 使用하여 關節炎을 誘發시킨 흰쥐에게 藥鍼을 施行하여 그 效果를 觀察하였다. Radioimmunoassy에 의한 PGE_2 含量을 測定하여 鎭痛 및 抗炎反應을 살펴보았고, 血液學的 檢査도 施行하였다. 또한 組織學的 所見을 觀察하여 組織의 損傷에 대한 回復程度를 比較檢討하였다. In order to investigate experimentally that Bovis Calculus, Ursi Fei Aqua-acupuncture(BUA) and Bovis Calculus, Susi Fei Aqua-acupuncture(BSA) have an effect on Arthritis in rats, the author inserted Aqua-acupuncture, electro-acupuncture, aspirin at corresponding with Chok-samni(ST36) and Hyunjong(GB39), and observed an concentration of the serum PGE_2 by method of the radioimmunoassay. The author also observed the histological feature of knee joint tissue. The results were as follows: 1. The BUA & BSA & aspirin group were decreased with statistical significance in the concentration of the serum PGE_2 as compared with the control group. 2. The BSA group were decreased with statistical significance in blood WBC as compared with the control group. 3. The control & experimental group were increased in blood RBC, Hb, Hct and decreased MCV, MCH as compared with the control group. 4. According to the histological studies, the BUA & BSA group were showed less than the control group in the damage of synovial cells and the least damage of synovial cells were showed in aspirin injection group.

Try to find a scheme for activation to College Physical Education, this Report informs the various kinds of Survey and process those were projected for improvement of management methods on Cultural Physical Education in Kang Weon National University. From experimentally carried out "Sports events Choosing System" not as usual be inforced "Total practical Skill System", Following Positive effects and sujestions were Presented; 1. "Sports events choosing system" gave birth to more students' interesting and more voluntary participation to the sports events they chose, and sports skill and instruction level was elevated due to charge of expert according to each sports events. This system would be managed continuously hereafter for it related to life sports. 2. This System needs to closed cooperations between College and Community, for the facilities of community are utilized by college. 3. To complete the plan for activation of college Physical Education, additionally, the successional study ; namely "autonomous extracurricular sports activity" should be excuted hereafter.

In this study we demonstrate that a small complex part of a tungsten-based heavy alloy (W-Ni-Cu) can be readily manufactured by utilizing the metal injection molding (MIM) technology. We use a simple thermoplastic binder system, containing low density polyethylene, paraffin wax, and stearic acid. To remove the organic binder from the molded part, we employ the solvent extraction and thermal debinding processes. Densification of debound parts is achieved by sintering in hydrogen atmosphere. The experimental results of the optimization of process variables to manufacture the heavy alloy part are described, with a brief discussion.

The Rayleigh ratio of benzene is a very important physical constant with which the integrated scattered intensity of laser light scattering can be converted into the absolute value. In this study temperature dependence of Rayleigh ratio of this solvent has been investigated with two different methods in the temperature range of 25-75℃. It was found that in the direct measurement the non-linear behavior of its Rayleigh ratio were observed as increasing temperature even if the scattering volume correction was applied to the scattered intensity of benzene. However the result of indirect measurement based upon the invariance of molecular weight of standard polystyrene polymer for any polymer solution temperature showed us that its temperature dependence up to 75℃ could be expressed with the Benoit's linear equation rather than the non-linear one. It seems that the scattered intensity in direct method has more complicate contributions at the elevated temperature. Further research works are necessary in order to solve such discrepancy clearly.
