팔라디움이 함유된, 시효경화성 치과주조용 고금합금의 연구를 위한 기초자료를 얻기 위하여, 4원계 □ 합금의 등온시효경화 거동과 상변태를 경도 시험, X선회절 실험으로 조사하여, 다음과 같은 결과를 얻었다. 본 합금을 250~350℃에서 등온시효처리하면, 면심정방구조를 갖는 준안정상 AuCu Ⅰ'형 규칙상이 면심정방구조를 갖는 AuCu Ⅰ형 규칙상과 면심입방구조를 갖는 Ag-rich a₁상이 생성되기 전에 생성되었다. 본 합금은 시효처리 온도에 따라 다른 시효경화 거동을 보여주었다. 350℃에서 시효처리를 하면, 경도는 시효 초기에 상승하지 않았고, 최고 경도에 도달하여 유지되고나서 시효시간을 연장함에 따라 경도가 급격히 저하하였다. 250℃에서 시효처리를 하면, 경도는 시효 초기부터 뚜렷히 상승하기 시작하였다. 그 후, 약간의 경도 하강을 보이고나서 경도는 다시 서서히 상승을 지속하였다. 350℃에서 경화는 준안정상 AuCu Ⅰ'형 규칙상의 균일핵생성에 기인하였다. 낮은 시효온도에서의 초기 경화는 다른 상변태에 의해 초래되었고, 이어서 일어나는 경화는 준안정상 AuCu Ⅰ'형 규칙상의 생성에 기인하였다. 시효시간을 연장함에 따라 생기는 과시효 연화는 평형상 AuCu Ⅰ형 규칙상의 생성에 기인하는 것으로 생각된다.

Dispersion stability of nanosized MnFe₂O₄ powders which was produced by glycothermal process were studied in aqueous suspension using ESA(Eletrokinetic Sonic Amplitude). The average particle size of the synthesized MnFe₂O₄was about 30±10nm. The dispersion and rheological behavior of MnFe₂O₄nanoparticles aqueous suspension was investigated using MnFe₂O₄as a disperse agent. The colloidal stability of nanosized MnFe₂O₄aqueous suspensions at different pH values has been investigated by means of zeta potential, sedimentation, average particle size and microstructure of green body. The isoelectric point of MnFe₂O₄powders is at pH around 5.5 and the value of zeta potential is at its maximum near pH 11.

A series of measurements and visualization to investigate the interaction of water sprays with pool fires is presented. Fire source is a small-scale pool burner with methanol, ethanol and gasoline. Measurements of temperatures, <TEX>$O_2$</TEX>, <TEX>$CO_2$</TEX>, and CO concentrations along the plume centerline are carried out to observe pool fire structures without water sprays. Visualization by the Ar-ion laser sheet shows flow pattern of droplets of the sprays above the pool fires. It is observed that in the case of methanol and ethanol, water sprays continuously penetrate into the center of fuel surfaces. The gasoline pool fire allows intermittent penetration of water sprays because of pulsating characteristics of the gasoline flame. To evaluate the cooling effect of the fuel surface by the sprays, the temperature was measured at the fuel surface. As soon as the mists reach the fuel surface of methanol and ethanol, the temperatures of the fuel surface decrease rapidly below the boiling point, and then the fires are extinguished. Due to the application of mist upon the gasoline fire, though the fuel temperature decrease abruptly at the time of the injection, such a rapid decrease do not continue till the extinction point.

China and Soviet opened the way in the 1980's to extensive reconciliation after a 30-years break in relations. This article has written to understand the current status and problems of the Sino-Soviet relationship. In chapter Ⅱ, on has to examine the stage of transformation in the major area of a 30-years history of Sino-Soviet relation. The stage of transformation can be classified by the 4 period. It is the period of friendship and alliance in the late 1950's, the controversary and distrust in the 1960's, the switching period of conflict and reconciliation in the 1970's, reconciliation and cooperation in the 1980's. In chapterⅢ, Sino-Soviet relations are structured by a complex and changing mix of pilitical-Ideoligical foreign policy, and economic consideration. It's attention is to analyze the variables of causes which can foster either firction between the two states or greater cooperation. First, the Ideological factor can play and have played a major role, but as recent trends suggest, friction and conflict are possible even in the absense of significant difference. Secon, The foreign and security policy of the USSR and the PRC are another major factor of Sino-soviet conflict-today as in the past. Especially, Soviet military deployment in Northeast Asia and Afghanistan, Indochina issues including Cambodian problems, and the difference of their Third World policy were and continue to be an important source of friction affection the Sino-Soviet relations. Third, The factor of economic interests can also influence the friction and cooperation between Sino-Soviet relation. In general, it would appear that the trend both of Soviet and Chinese economic policy and economic development is conducive to expanded economic ties in the future. In Chapter Ⅳ, as the conclusion of this article, the prospects for reconciliation and cooperation would be much expanded, although the three obstacle that Chinese see as impending full normalization of relation have not been removed, because the aim of two state policy is to work steadily to broaden the base of contacts and cooperation with each other.

이데올로기論의 體系的 分析

裵漢東 慶北大學校 1982 論文集 Vol.34 No.-

It is often said that the twentieth century is an age of ideology. This is to say that all people in the world are to be placed inevitably under the restrain of certain ideology in their lives, consciously and unconsciously. People want to live free from any kind of ideological burden, but they often become the victims of ideology they have believed in. Needless to say, it is important to study systematically the origin and nature of ideology, and various theories of ideology. However, not many studies in the subject have been endeavoured, and even the few achievements have not been accepted as systematic studies of it. With this perspective, this study investigates, first, various meangings of "ideology" which have appeared in the writings of great thinkers, such as Desttue de Tracy, Karl Marx, and Karl Mannheim: second, categorzing those concepts into the positive and negative ones, and again into the common and extreme ones, it tries to answer the question of "what is ideology": third, it analyzes the origins and sources of various concepts of ideology: fourth, it discusses some arguments about the theory of the "End of Ideology", and the relationship between technology and ideology; fifth and lastly, it tries to single out functions and disfunctions of ideology in psychological and sociopolitical aspects, and raises some questions that should be answered for the future study of ideology.

In general, the viscosity of fluid increases as temperature decreases, and decreases as temperature increases. This phenomenon can be explained by decreasing mobility of molecules as temperature decreases. But, we found the opposite phenomenon that viscosity decreases as temperature decreases in particular mixed surfactant system. To analyze this phenomenon, various experiments have been proceeded such as composition (anionic, nonionic, zwitterionic surfactant), variation of zwitterion surfactants, structure of hydrophobic chains, structure of Hydrotrope, variation of pH. Conclusively, controlling the complex of zwitterion and anionic surfactant, we could control the viscosity of mixed surfactant system on variation of temperature. We analyzed this phenomenon theoretically, and then can complete "The technology of viscosity control by temperatre in micellar phase".

배동환 순천향대학교 1991 논문집 Vol.14 No.2

A comparative clinical study on the effectiveness of bromocriptine and lisuride in suppressing puerperal lactation was carried out in 40 cases of puerperal women, evaluation clinical findings of milk seeretion, breast engorgement and pain, and determining serum prolactin levels. The first group of 20 women took bromocriptine 5㎎ daily and the second group of 20 women took lisuride 0.4㎎ daily for 14days. In the first group, milk seceretion was observed in 20% of the patients on the 3rd day, 10% on the 5th day and none on the 7th day, whereas 5% on the 1st day, 25% on the 3rd day, and none on the 7th day in the 2nd group. After discontinuation of the treatment, rebound lactation was observed in 25% in the 1st group, but 15% in the 2nd group. However, rebound lactation was mild and stopped in both group with further treatment for one week. In both groups, the antepartum serum prolactin levels were about 114∼221ng/m/and after bromocriptine & lisuride therapy, serum prolactine levels were lowered below 37ng/ml within 5days. Lisuride produced no remarkable untoward side effects. In conclusion, there was no statistical difference in the effectiveness on suppression between both groups. but, the 2wk's therapy was effectively inhibited lactation and suppressed the serum prolactin levels.

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.
