Five-coordinated complex of Cu(Ⅱ) complex, [CuCl(1,10-phenanthroline)₂]·Cl·6H₂O·CH₃OH, was synthesized by adding an aqueous solution of Cu(Ⅱ) to a methanol solution of 1,10-phenanthroline. Its crystal structure was detemined by single crystal X-ray crystallography. Crystal data are are as fllow: [CuCl(phen)₂]·Cl·6H₂O·CH₃OH, monoclinic, space group C2/c (#15), a = 23.309(5), b = 30.270(6), c = 7.491(2) A, B = 97.83(2)˚, V = 5236 A³, Z = 8,2745 data with I >3σ(I) (R = 00.64, Rw = 0.087). In the crystal structure of ??, the Cu(Ⅱ)is five-coordianted with four nitrogen and one chlorine atom. The geometry around Cu(Ⅱ) is somewhat distorted trigonal bipyramid and Cu(Ⅱ) is locted nearly (0.0280 A˚) on the least-squares plane of the two nitrogen atoms and one chlorine atom.

Crude saponin(100g) were obtained by extracting the radix(5kg) of Scrophalariae koraiensis Nakai. Crude saponin were positive in the Liebermann-Burchard test. We observed 5 sports by TLC using BuOH saturated with H_2O : ethyl acetate : water(4:1:5, upper phase) as solvent and 1% Ce(SO_4)_2 in 10% H_2SO_4 as a color former. We divided into 3 fractions by common column chromatography using BuOH saturated with H_2O : ethylacetate : water(4:1:5, upper phase) as solvent.

Far East asian history in ancient and the middle ages was expansion of territory by the territorial ambitions and the series of revenge among mutual dynastys of Far East asian continent. Gogooryu dynasty is more offensive than the defensive against foreign country in BC I century and I century and 2 century. Gogooryu dynasty is more defensive than the offensive against foreign country in 3 century. Gogooryu dynasty is more offensive than the defensive against foreign country in 4 century. Gogooryu dynasty's attack and the defensive againast foreign country is same in 5 Century. Gogooryu dynasty is 9 times more offensive than the defensive against foreign country in 6 century. Gogooryu dynasty is 12 times more defensive than the attack against foreign country in 7 century.

The results were obtained with changes according to the surface roughness of work roll and method to make the peak count on the roll in the temper rolling, and factors to affect the work roll surface in actual roiling machine (ie. Temper mill). Conclusions are as follows. 1. E.D.T(Electro-discharge texturing) roll provide more uniform roughness distribution than the shot blasted roll, and it's life time is two times longer than that of shot blasted because it has more sine wave roughness. 2. The higher the peak count of surface roughness, the more time is necessary to work roll texture in shot blasting method, surface roughness is relating to the grit size, impeller speed and hardness of roll material, But it can not control the peak count. 3. In shot blast texturing, Surface roughness of temper rolled strip which is transferred surface roughness of work roll is more than that of E.D.T roll. 4. E.D.T roll has more uniform than the shot blasted roll and has more peak count than that of shot blasted roll. The surface of painted strip to image clarity is superior to that of shot blasted roll because E.D.T roll has more peak count and smooth surface.

This study is on the Korean wooden architecture's Corner Bracket Sets(Gui-kongpo) and one of these elements "Yibang(耳枋)". The Purpose of this study is to understand the relationship between "Yibang(耳枋)" and Korean wooden architecture's structure system. To conduct this research , it is important to analysis its type and structure system in korean wooden architecture "Dapogye". The basic conceptions of "Yibang(耳枋)" are sought, its character and shape is actual surveyed through 140s object buildings in this study. In result, first of all, Using period of "Yibang(耳枋)" is Chosun dynasty and "Yibang(耳枋)" appears in wooden architecture style "Dapogye". Second, the size of roof isn't related with "Yibang(耳枋)", and it's duty is up to Corner Bracket Sets(Gui-kongpo). Third, the buildings with "Yibang(耳枋)" get more 'numerical value ; a2/b' than buildings without "Yibang(耳枋)".
QMF를 이용한 대역 압축 시스템에서의 스크램블링 효과
주언경,蔡鍾吉 慶北大學校 1992 論文集 Vol.52 No.-
Scrambling has been used as a method to encrypt the transmission signal for purpose of service protection from illegal use of unauthorized subscribers in Conditional Access system. More recently it is proposed to be used in a HDTV system such as MIT-CC in order to turn ghost, correlated noise, to uncorrelated white noise. In this paper, band rotation scrambling method using a modified line rotation is proposed for the band-compressed system using QMF. And scrambling effects on conversion of ghost to white noise and service protection are studied and analyzed. As results, effects of whitening ghost and service protection by the proposed method are shown to be superior to the existing line rotation method.

The purpose of this paper is to define the kinds and the characters of pseudo-syntactic construction. Pseudo-syntactic construction is the same as syntactic construction in form but each element doesn't have individual syntactic function and it's a construction that the elements become a unit and has a syntactic function. Because of this formal and functional character pseudo-syntactic construction has a character that is between syntactic construction and morphologic construction. That is, pseudo-syntactic construction has more syntactic restrictions than syntactic construction but less than morphologic construction. So it becomes morpho-syntactic construction. This pseudo-syntactic construction has idiom, modality-adverb construction and catenative construction. Idiom is the one that has new meaning that can't abstract from the two elements. Modality-adverb construction is the construction that co-occurs particular grammatical features and psychological attitude of the speaker. Catenative construction is a construction which later element is dependent and adds grammatical meaning.

The effect of water extract of Poncirus trifoliata fruit (ATFE) on compound 48/80 induced anaphylaxis was studied in the rat. The following results have obtained. 1. Optimal lethal dose of compound 48/80 was 8ug/gm B.W. 2. PTFE was found to exhibit an inhibitory activity on the anaphylaxis induced by compound 48/80. 3. Administration of PTFE 60 min before or 5 min after had a better result than 10 min after anaphylaxis induced by compound 48/80. 4. PTFE also inhibited significantly the serum histamine release in anaphylaxis induced by compound 48/80 in the rat. 5. Administration of PIFE before 30 min decreased PCA reaction induced by anti DNP-IgE and DNP-HSA. This result indicates that poncirus trifoliata suppresses the anaphylaxis induced by compound 48/80 with decreasing the serum histamine release.
C_22-Quinolium(TCNQ) Langmuir-Blodgett 박막의 온도변화에 따른 분광학적 특성
洪彦植 홍익대학교 산업기술연구소 1994 産業技術 Vol.3 No.-
C22-Quinolium (TCNQ) Langmuir-Blodgett films were made and the annealing-temperature dependent optical properties were investigated. UV/visible absorption and FT-IR spectra were measured. It was found that there is a change in chemical structure near 180℃. When the annealing temperature is over 200℃, the chemical structure of the molecules seems to be destroyed.

A cold spot temperature control system for the BAF(batch annealing furnace) has been established in order to reduce energy consumption to improve productivity and stabilize the properties of products. Therefore we confirmed for the improving of material quality (eq. even and consistent tempering, high surface cleanliness, reduced carbon depositing etc.), increasing of output, comparison of annealing cycle time, reducing of annealing cost and distribution of cold spot temperature according toe BAF type. The use of hydrogen instead of nitrogen as the protective gas, combined with high convection in batch annealing furnaces, has shown that considerable increases in furnace output and material quality are attainable. Owing to the low density, high diffusion and reducing character of hydrogen, a better transfer resulting in uniform material temperatures and improved coil surfaces can be achieved.
