린탄나이드 3가〔Dy(Ⅲ), Tb(Ⅲ)〕와 유기리간드들의 착물을 전기화학적인 DC와 DP, SP 그리고 CV방법으로 조사하였다. 란탄나이드 착물들인 Dy(hafc)_3와 Tb(phen)_3의 전기화학적 환원을 비수용매 속에서 연구하였다. 란탄나이드 3가 착물들은 Ag/Agcl전극에서 이들 환원 피이크는 E_pc=-1.15V, 그리고 -1.45V의 비가역적인 일전자 환원과정이었고, 무거운 란탄나이드에서 원자번호가 증가함에 따라 안정도상수는 감소하였다. The electrochemical behavior of trivalent lanthanides, Dy(Ⅲ) and Tb(Ⅲ) Complexes were investigated by the use of direct current, differential pulse, stripping pulse polarography and cyclic voltammetry. The electrochemical reduction of lanthanide complexes 〔Dy(hafc)_3〕and 〔Tb(phen)_3〕were investigated in aprotic media. These reduction peak were irreversible one-electron processes at E_pc=-1.15V and -1.45V Vs. Ag/AgCl electrode and the behavior of the heavier lanthanides were decreased stability constant with increasing atomic number.

원시림이 없는 한국에 산림생태계 이해에 근원이 될 자연림은 매우 중요한 의미를 가진다. 설악산에 존재하는 몇몇 전나무 고목림의 자연성을 판단하기 위하여 국제적으로 통용도는 원시림 혹은 자연림의 특징과 임분 동태학을 산림생태계 변화(천이)의 기본으로 상정하고 조사를 진행하였다. 비록 면적은 좁지만 모든 조사지역은 자연성을 확실히 보이고 있으며 수집된 기초자료는 한국 자연림 연구의 밑거름이 되리라 사료된다. Abstract - Natural forest stand plays a very important role to understand the forest ecosystem in Korea, in which there is no ancient forests are left. Several old growth Korean fir stands were studied to determine their naturalness. Internationally accept- ed criteria for virgin or natural forests were used and the changes in several stages by stand dynamics were applied. Although the areas survey is limited in size, it was discovered that they clearly represent certain characteristics of naturalness. This study and collected data will hopefully be the starting point for the further studies for naturalness of forest in Korea in the future.

This paper is an exploratory study to examine the relation between ability to pay wages and wage level of firm for developing the index of ability to pay wages. When we take the trends of Labor-Management Relations, especially wage negotiation, into consideration, to negotiate wage level rationally the index of ability to pay wages is needed. The procedure followed in the research on which this paper is based was divided into two phases. First, developing probable indices of ability to pay wages conceptually by examining literatures was made. Second, by using published corporate accounting data relations between conceptually probable indices and wage level differences among firms in metal industry are tested empirically. Based on synthesizing conceptual and empirical research results, research results are as follow. First, wage level differences among firms result from firm-by-firm differneces in estimates of their abilities to pay wages. Second, The usable indices of ability to pay wages are net value-added per laborer, total share per laborer, and maximum distributable to laborer per laborer. And each index has high correlation with wage level and there is high correlations among three indices. So these indices are usable selectively. Third, net value-added is better index than gross value-added. Finally the implications in relation with developing indices of ability to pay wages usable for wage level determination are suggested.

This study aims to analyze the antecedent factors of indirect participation programs empirically. After rearranging dimensions of characteristics and antecedent factors of indirect participation programs with focus on Works Council, this study applied questionnaire method to 67 companies with union in metal industry. The results which are found empirically are as follow; First, in sample companies the level of activation of Works Council is generally low. Second, the antecedent factors to be related significantly with dimensions of effective characteristics of Works Council are union's capacity, autocracy, employer's acceptance of participation, employer's effort to make cooperative industrial relations, and union's activation of promoting participation. Third, being different from the existing results of studies, conditions of work, level of opposition in industrial relations, position in market and growth ratio are not the antecedent factors to account for level of activation of Works Council significantly. Based on the these empirical results, the visions and tasks of Korean company's activation of participation in future to be derived are as follow; If possibility to change will be low in the condition that union's capacity is weak and employer's attitude to participation is negative, possibility of activation of participation in Korean companies will be low. Thus in order to activate indirect participation programs, labor movement must seek to strengthen union's capacity and employer must seek to change attitude to participation toward the positive direction. And then, the limitations and suggestions are put forth.

It has been reported several viral diseases in soybean. The occurrence of Bean common mosaic virus and Peanut stunt virus are able to induce severe problem because the main breeding target for viral disease was focused on Soybean mosaic virus. BCMV is a spcies of the genus Potyvirus of the family Potyviridae. BCMV reduces yield by as much as 80% and also adversely affects seed quality in common bean. BCMV has a worldwide distribution because of its high rates 35% of transmission via seeds produced by plants systemically infected prior to bloom. PSV is a species of the genus Cucumovirus of the family Bromoviridae. PSV has been reported to be economically damaging on beans worldwide. Although the virus is reportedly seed transmissible at very low rates, infected plants rarely produce pods with normal viable seeds. The most satisfactory management method of viral diseases such as BCMV and PSV is the use of resistant cultivars and healthy seed. For the overcome of genetic resistance by new virus such as BCMV and PSV, virus diseases monitoring and researches need to study deeply and continually. In this study, we conducted the resistance screen on BCMV and PSV for selection of resistance cultivars. We inoculated on 128 cultivars with PSV and BCMV respectively. These cultivars were classified through pathogenic response such as resistance, necrosis and susceptibility. In addition, 99 and 66 resistant cultivars were confirmed against PSV and BCMV respectively.

Purpose: The purpose of this study was to identify the needs of health education in students, their parents and teachers in the elementary, middle and high schools and the current situation of health education class. Method: The subjects of this study were a total of 9450 persons including students, their parents and teachers from 279 schools throughout the country. They were selected through convenient sampling. Data were analyzed through x^(2)­test and ANOVA. Result: Students, their parents and teachers replied that 18 dimensions of health education class (DHEC) are necessary. The four DHEC - healthier life style, sex education, mental health and safety education - showed high educational needs in students, their parents, and teacher. High school students had higher educational need of 'symptom management for daily living' than elementary and middle school students. Students, their parents and teachers in elementary school had higher educational needs of 17 DHEC that those in middle and high school. The percentages of schools with health education class taught by health teachers were 99.2%, 75.5% and 66.0% respectively in elementary, middle and high schools. Health education was given mainly using physical education classes at elementary schools, and creative class hours at middle and high schools. In general, health education took 1-3 hours per week at elementary schools, and less than an hour at middle and high schools. Conclusion: Therefore, based on the results, systematic health education class should begin from elementary school to meet the need of health education in students, their parents and teachers, and further study should be made on the number of hours required and the amount of contents of 18 DHEC.

We are usually satisfieel with the explanaton of existence of roots in an equation or with the simple analytical expression of the answer which sometimes results in limitless calculation! However when we think of another side of an equation related with the concrete, practical problems in our nature and society, we can't be satisfied wrth the simple thesretical results. In the long run, the answer which is not expresseed by the practieal and concrete figures in the practical, concrete, real problems, is sometimes meaningiess, Accordingiy to solve this problem, the method of practical analysis is to be worked ont and then the real veal value which can't be expressed is to be answered by approximation. It is what I want to discuss in this thesis. I cliel not touch the generalsoluion of an equation. In this thesis I don't want to introduce the unexploi ted field or to discuss and criticize the new theories, but to introduce the general tendency of modern mathematics, Practical analysis is sometines neglected by some mathematcians. Here I want to discuss this problem for the beginers whs are earnestly stndying it first of all prior to this problem, general consideration onpractical analysis has to be mentioned, but Iomitted it on account of space consideration. In Chapter Ⅰ, Main points of discussion and referred books were introduced In Chepter Ⅱ, The method of numerical solution, that is to soy, the method, by tables and iteration, and the methods by Newton, Horner and Graeffe were mentioned, In Chapter Ⅲ, The methods dy Segner and Lill grounded on graphical calculation and methods applying intersection chart and nomogram were introduced. In Chaptor Ⅳ, The methed using calcnlating machine was to be discussed, but I omitted it onaccornt of space consideration, I cdosed my discussion mentioning matters that demand special atlention on practical calculatcon, and modern tendency of mathematic education.
