      • 폴리프로필렌 纖維用 Carbene染料의 開發에 關한 硏究

        李學沂,林龍進,민경은 慶北大學校 1982 論文集 Vol.33 No.-

        Reactive dyes, which reaction center is carbene, were prepared and the dyeability of polypropylene fiber by those dyestuffs was investigated. Furthermore, a new say of dyeing and an applied technique for pretreating polypropylene with carbenic precursor were studied to improve dyeability. In this experiment, ketones were used as starting materials because these are mostly common functional group in dyes and dyestuff intermediates. Ketones could be changed to tosylhydrazone derivatives by tosylhydrazine in methanol at 0℃ in the presence of aqueous hydrochloric acid. Reactive carbenic dyes were prepared by the reaction of n-butyllithium and these hydrazone derivatives in ethly ether solvent. Dyed polypropylene showed excellent endurance to the light and preserverance to laundry, which were confirmed by means of blue and gray scales. The fact that polypropylene was bonded covalently to dyestuff molecules was confirmed by extraction and reprecipitation. Using the aldehyde as the starting material, carbenic precursor was also prepared analogous route to the dyestuff. After pretreating polypropylene fiber with this precursor, dyeing pattern of fiber in acidic media with butyl orange showed similar adsorption curve which is the typical results of acidic dyeing process. It means that polypropylene could be dyed easily in acidic media if it had pretreated by carbenic precursor.

      • 소련帝國主義 戰略과 그 苦悶

        孫慶學,朴泰岩 대구교육대학교 1982 論文集 Vol.18 No.-

        This paper is attempted to search for the strategy of Russian imperalism and its agony. Over six decades after the establishment of the Soviet state and several decades since Churchill expressed his mystification concerning the mainsprings of Soviet policy, many Western foreign affairs observers and practitioners continue, surprisingly, to ask fundamental questions about the motivations and modalities of soviet international strategy. The Soviet government has looked toward western agriculture, technology, trade and finance in order to relieve the pressing economic problems of eastern Europe and of the Soviet Union itself. The Soviet leadership, Andropov regime is likely to shape it policies for the 1980's in the knowledge that changing public attitudes in the United States can be expected to result in serious efforts to restore both America's defense capability and its deterrent credibility. The apparent military, psychololical and political adventages are likely to diminish as the decade proceeds, the Andropov regime may be tempted to pick up key pieces on the chess board before the West begins to close the perceived "window of Vulnerability". In implementing this line, Soviet leaders are likely to be impelled by their penchant for the initiative, believing that an opponent who seems to be both reacting and trailing can be confronted with particulary unpalatable options.

      • 수지(手指)에 발생한 Glomus Tumor - 치험 2례 보고 -

        신경현,김준영,윤치순,최창욱,김학현 순천향의과대학 1978 Journal of Soonchunhyang Medical Science Vol.1 No.1

        Glomus tbmor of the hand has been well documented lesion that usually presents as painful dermal nodule in the finger. Glomus tumor may be difficult in diagnostic and therapeutic problems because of relatively rare and not easily experienced cases. Normal glomus body presents in the skin and subcutis of the extremity, but the normal body is not more than 1 mm3) in size. Most evidence indicates that the main function of the normal glomus body is to aid in regulation of the skin circulation. The glomus tumor is thought to be an abnormal proliferation of the glomus body and accompained by the classic triad of symptoms : pain, tenderness and temperature sensitivity. This paper reports two cases of glomus tumor occurring in the nail bed and finger pulp. One case was found 30 years later & another case 15 years after the onset in spite of srvere pain, tenderness and lancinating pain when exposed to the cold tempera ture but the excision of the tumor resulted in complete recovery.

      • 더블 니트 편성물의 열차단 효과

        최경은,김학용,이덕래 全北大學校 附設 都市및環境硏究所 2000 都市 및 環境硏究 Vol.15 No.1

        In this study, testing materials were prepared with 50 kinds of double knitted fabrics on sales which 1×1 rib and interlock consisted by different yarn count N_e 30, 40, 45, 50, 60 and P/C 45. The relationship between thermal resistance of double knitted fabrics and structural parameter by statistical analysis was discussed. The regression equations could be obtained between thickness and yarn count of double knitted fabrics by means of multicuervilinear regression analysis. The results were as follows. Clo values were decreased with an increase of thickness, bulk density and weight but increased with porosity, specific volume and permeability in rib knitted fabrics R_(rib) = -0.4669 + 29.395(T) - 0.0034(C) + 0.0001(C^2) - 2.3792(T^2) - 0.0102(CT) R_(Interlock) = -0.1344 + 1.767(T) + 0.0103(C) + 0.0001(C^2) + 0.4364(T^2) - 0.0192(CT) Where R = thermal resistance of the knitted fabrics (㎡/℃/W) T = thickness of knitted fabrics (mm) C = count of knitted fabrics (Ne)

      • 적층형태 및 보강방향에 따른 복합적층판의 종방향 모멘트 무시효과

        이봉학,홍창우,이정호,김경진 江原大學校 産業技術硏究所 1998 産業技術硏究 Vol.18 No.-

        The most of the design engineers for construction has academic background of bachelors degree. Theories for advanced composite sturcutures are too difficult for such engineers and soe simple but accurate enough methods are necessary. The senior athor has reported that soke laminate orientations have decreasing values of D?, B?, D? and B? stiffnesses as the ply number increases. Such plates behave as special orthotropic plates and simple formulas developed by the author can be used. Most of the bridge and building slabs on girders have large aspect ratios. For such cases further simplification is possibe by neglecting the effect of the longitudinal moment terms(M?) on the relvant partial differential equations of equilibrium. In this paper, the result of the study on the subject problem is presented.

        금호강 유역 산림의 경관생태적 패턴분석

        박경훈,정성관,이현택,오정학,김경태 한국지리정보학회 2004 한국지리정보학회지 Vol.7 No.3

        산림의 단편화와 같은 인위적 교란은 유역생태계의 지속성에 영향을 미치기 때문에, 본 연구는 각종 개발사업에 따른 산림의 단편화를 사전에 예방하기 위해서 경관지수와 GIS를 이용하여 금호강 유역에 분포하는 산림구조를 정략화하였다. 소유역 단위의 경관지수값은 인자분석에 의해 전체분산을 또% 정도 설명하는 3개의 공통인자를 단순화하였다. 산림단편화 정도는 소유역별 인자점수를 토대로 계산하였고, 이는 도시지역 면적률(r=0.827, p<0.01, R2=0.685), 고도(r=-0.637, p<0.01)그리고 경사도(r=-0.593, p<0.01)와 상호관련성이 있는 것으로 나타났다. 이상과 같이 본 연구는 금호강 유역관리를 위한 산림경관의 건전성 및 구조적 패턴을 평가하기 위한 방법론과 경관지수값을 제시하였다. 향후에는 경관패턴 및 그 변화가 유역환경의 건전성에 미치는 영향을 규명하기 위한연구가 필요할 것이다. An artificial disturbance like fragmentation in watershed forest has impacted a sustainability of watershed ecosystem, therefore this research quantified the landscape structure in the Geumho river watershed using landscape indices and GIS. Landscape indices were calculated from the forest distributed maps for 24 subwatersheds. Three common factors, which explained about 85% of the variation in the original data, were extracted by a factor analysis. The fragmentation gradient in forest landscape, which was calculated from the factor scores, was correlated with proportion of urban land (rte. 827, p<0.01, R²=0.685). elevation (r=-0.637, p<0. 01) and slope gradient (r=-0.593, p<0. 01) . The result of the study presented that the methodology and the values of landscape indices to assess the structural patterns of forest landscape for the Geumho river watershed management. Future research will be directed towards the detection of impacts of landscape patterns and their changes on the integrity of watershed environments.
