This study was aimed at investigating the typical pattern of occupational socialization, which could be developed in the continuous process in terms of their longitudinal aspects from before entering National University of Education and through the university period, of prospective elementary school teachers nationwide. Being based upon the assumption that the occupational socialization is a result of continuous and developmental process, main interest of the study was to find how prospective teachers enrolled in National University of Education establish and develop the identity of teaching profession. The variables used in this study are categorized into three groups. Input variables are related to prospective teachers' attitudes and values before their entering to National University of Education. Process variables are related to various experience and values of prospective teachers during National University of Education period. Output variables are identified as willingness to hold teaching profession and satisfaction with the decision to become a teacher. A review of the related literature and survey research were employed in this study. The sample for the survey covered about 2,000 students enrolled in 11 National University of Education nation wide. Collected data was analyzed by descriptive statistics and Analysis of Variance(ANOVA) using SPSS(Statistical Packages for the Social Sciences) to find out the relationship among variables related to the occupational socialization process. Major finding of the study were as follows. 1) Most of students showed their willingness to hold teaching profession and satisfaction with the decision to become a teacher. Also, It was found that willingness to hold teaching profession was closely related with the satisfaction with the decision to become a teacher. 2) Input variables showed close relationships with output variables of occupational socialization of prospective primary teachers. Sub groups showed statistical differences in both their willingness to hold teaching profession and satisfaction with the decision to become teachers in accordance with variables such as motivation of selecting the teaching profession and significant others who reinforced being teachers before entering National University of Education. 3) Many process variables showed close relationships with output variables of occupational socialization of prospective primary teachers. Sub groups showed statistical differences in both their willingness to hold teaching profession and satisfaction with the decision to be teacher in accordance with variables such as significant others who reinforced being teachers during National University of Education life, confidence level for selecting teaching job after on-the-fob practice, attitude toward real education situation after on-the-job practice, overall attitude toward teaching profession. Based upon the results of the study, the following suggestions are drawn out. 1) The student selection policy of National University of Education should put more stresses on applicants aptitude and motivation of selecting the teaching profession to develop them to be professional and effective teachers. 2) Authorities including professors in National University of Education should be concerned with the occupational socialization process of students to help them to be effective teachers with being satisfied with teaching profession in their future career. 3) In terms of the importance of primary education at national level, various studies relating occupational socialization of primary teachers should be followed by. Results of these studies could offer significant information and suggestions to be reflected into policies of each National University of Education.

주게전자가 ONNO인 네자리 리간드, ethylenediamine-N, N'-di-α-isobutyric acid(eddib)를 합성하고 이 리간드의 디클로로 코발트(Ⅲ) 착물을 공기산화법에 의하여 합성하였으며 이 착물의 uns-cis이성체와 s-cis이성체를 이온 교환 크로마토그래피법에 의하여 분리하였다. 그리고 eddib의 디클로로 코발트(Ⅲ) 착물을 용액중에서 Co(eddib)L^n+(L=Cl·H_2O,CO_3^2-, (H_2O)_2)로 치환반응을 시켰을때 이들의 전자흡수 스펙트럼의 흡수띠 위치가 분광학적 계열과 일치함을 알 수 있었다. A new flexible N_2O_2-type tetradentate ligand, ethylendiamine-N, N'-di-α-isobutyric acid (eddib), has been synthesized, and dichloro cobalt (Ⅲ) complex of eddib has been prepared via the airation method. The geometric isomers of the complex, s-cis and uns-cis isomers, have been separated through ion exchange chromatographic method. Aseries of cobalt (Ⅲ) complexes of eddib, [Co(eddib)L]^n+ (L=Cl. (H_2O), Co_3^2-, (H_2O)^2) have been prepared in solution. In their electronic absorption spectra, the absorption maxima and their intensities of the above series of complexes are on the ordinary line of the spectrochemical and hyperchromic series. Elemental analysis, IR, NMR and electronic absorption spectra have been used to characterize the complex and geometries of the complex.

네자리 리간드인 ethylenediamine--N,N'-di-α-butyric acid(eddb)의 디클로로 로디움(Ⅲ)착물을 합성하고 크로마토그래피법으로 분리하였다. Eddb리간드가 로디움(Ⅲ) 이온에 배위될 때 s-cis와 uns-cis기하 이성체가 형성됨이 관찰되었다. 합성된 착물의 구조는 적외선 분광분석법, 핵자기 공명 및 흡수 스펙트럼으로 확인되었다. Dichloro rhodium(Ⅲ) complex of a flexible tetradentate ligand of ethylenediamine-N,N'-di-α-butyric acid(eddb) has been prepared and separated by the chromatographic method. S-cis and uns-cis geometric isomers have been yielded during the preparation of complex. IR, PMR and electronic absorption spectra have been used to characterize the complex.

최승락,전무진,이숭실,천진우 연세대학교 대학원 1990 延世論叢 Vol.26 No.1

Abstract A optically active novel ONNO-type tetradentate ligand, ethylene-diamine-N-N'-di-S-isobutylacetic acid(SS-eniba), has synthesized. During the preparation of cobalt(III) complexes of SS-eniba, [Co(SS-eniba) (H2O)2]+, the ligand has coordinated stereopecifically to the cobalt(III) ion to give three isomers, △-s-cis, △-und-cis and Λ-und-cis, which hove been isolated and characterized via electronic absorpion, circular dichroism and PMR spectroscopy, along with elemental analysis data. The s-cis-[(Co(SS-eniba)L] complexes(L=2NO2, L-ala) have been synthesized via substitution reaction. The absorption maxima of the complexes have been on the ordinal line of the spectrochemical series and the retention configuration has been observed during the preparative reactions.

Palladium(II)-catalyzed carboxylation of chiral olefins 6a-d has been examined under various conditions. In the weak basic condition ($K_{2}CO_3$), 7a-d were obtained in good yields. Alternatively, in the strong basic condition, pyrrolidinones 8a-d were obtained resulting in excellent yields and with high diastereoselectivity.

Y형 제올라이트의 탈알미늄과 그의 특성

최상준,손종락,류삼곤 한국화학공학회 1989 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.27 No.2

Y형 제올라이트를 높은 온도에서 SiCl₄, 수증기 및 EDTA로 처리하여 일련의 탈알미늄화된 제올라이트를 만들었다. SiCl₄로 탈알미늄화된 제올라이트는 수증기나 EDTA로 탈알미늄화된 것에 비하여 결정의 파괴없이 완전하였다. 그리고 탈알미늄화 제법에 관계없이 0-(Si, Al)-0 신축진동에 의한 적외선 흡수 밴드는 단위 세포당의 골격구조의 Al 원자수가 감소함에 따라 높은 파수쪽으로 이동하였다. 높은 파수(3640㎝^(-1))에 있는 수산기 밴드는 골격구조의 Si/Al비가 약5까지는 Si/Al비가 증가함에 따라 거의 선형적으로 저파수쪽으로 이동하였으나 Si/Al비가 5이상에는 변하지 아니하였다. 탈알미늄화됨에 따라 제올라이트의 net 정전기적 하전의 감소 때문에 수분을 흡수하는 능력이 감소하였다. A series of dealuminated Y-type zeolites was prepared by treating zeolites with SiCl₄, steam, and EDTA at elevated temperatures. Y-type zeolites can be dealuminated by reaction with SiCl₄ without collapse of the crystal structure as compared with the treatment of steam and EDTA. Regardless of preparation method, the infrared absorption bands in frequency of the stretching O-(Si, Al)-O vibrations shifted in a linear manner as number of framework Al atoms per unit cell. The high-frequency hydrouy band (3640 ㎝^(-1)) decreased in wavenumber almost linearly with an increasing Si/Al ratio of the zeolite, but beyond a ratio close to 5, the frequency remained virtually unchanged. Upon dealumination the ability of the zeolite to absorb water decreased due to the decrease of net electrostatic charge.
