Measurements of the electromagnetic lifetime of 2g+ staate in Sm-152 have been made by the TPHC method. Single gamma spectrum of Eu-152 taken with a Ge(Li) detector is analyzed by using DEC PDP-11/23 computer. From the results the energies and relative intensities were obtained. The partial lifetimes of the principal transitions were computed from the previous results. The expressed their results in terms of the reduced transition probabilities (B (E2) and B(M1) of the principal electromagnetic transitions. The present results are compared with calculatins based on the Interacting Boson Approzimation (I.B.A.) model. The values yidlded results in good agreement with I.B.A. model.

To see the possibility of Individualized Study, after analyzing the Unit, 'Force and Movement' I chose appropriate sub-subjects and made the plans of education directions and the materials of individualized study according to the respective sub-subjects. And then, I directed the first grade middle students naming the title 'The Attitude Change of the Middle Students by Individualized Study.' And using the individualized teaching method, teachers are required to prepare the materials which is considered about the level of the students. And it is needed for them to develop various materials themselves and direct their students to use their time efficiently and study science with interest according to their abilities.

The purpose of study is to reveal the true nature of home education in the Yi dynasty, is to its focus on the relation between parents and the home education of children The research project from which we are drawing our present report was directed toward the following four related tasks : 1. To identify of the Social Structure on the Yi dynasty of korea. 2. To examine on the educational role of parents. 3. To examine on the educational role of the brothers and sisters. 4. To identify of the contents on the home education. The conclusion from the study are as follow : First, The basic nature of home is the happiness and love, These are matters which determine all the relationships maintenance and searches of child. Second, The basic nature of home education of parents is the maternal love and paternal fear. Third, The basic nature of brothers and sisters is the brotherhood and social relation. Accordingly we should create our culture a new through a new synthesis, accepting the merits of western culture on foundation of our history tradition and natural features and furthermore set up our home education along the same lines.

이관영,한국희 대구대학교 산업기술연구소 1991 産業技術硏究 Vol.10 No.-

Drainage area is found to be the most important factor in the river morphological characteristics of small river basin. For the analytical study of the characteristics of drainage area, the river basins of Sab-Gyo, Mu-Han and Gok-Gyo Rivers are divided into the equal length along the course of river. This study employs the stream order and analyses the river basins using the statistical theories. The characteristics of run-off and physiography of small river basins havings similar conditions in morphological characteristics are predicted from the selected model of Sab-Gyo river and its branches. The results of this study are as follows: 1) The theoretical ratio of drainage area shows a good agreement with that of actural drainage area when the number of division of river course has the values of 13 of 14. 2) The distribution ratio of drainage area is found to be about O.174-0.189. 3) This analytical method is considered as powerful way for understanding the characteristics of small river basins having mostly a stiff topography.

The purpose of this paper is to aim at Promoting the general level of creative thinking among elementary-school childern and to Consider some of the pedagogical implications of such research, especially regarding the value, feasibility, and Justification of teaching for creative functioning. This paper should be noted that most of the current attempts to develop such teaching materials, that all children can be taught to make fuller and more appropriate use of their capacities by means of systematic and direct training of certain cognitive skills. The Conclusion from the study are as follow; First, The creative child is generally agreed that he is intellectually curious and exploratory, taking an active part in manipulating and reconstructing his environment. Second, The relationship between the Creativity and the I.Q are the relatievly low Correlations The creative factor consist of the fluency, the Flexibility, the Originality, the Elaboration, the Organization. Finally, In order to think Creatively the child have to develop curriculum programs aimed at promoting the general level of (creative thinking

퍼지 가변 스텝 크기 LMS 알고리즘

이철희,김관준 江原大學校 産業技術硏究所 1993 産業技術硏究 Vol.13 No.-

In this paper, a new LMS algorithm with a fuzzy variable step size (FVS LMS) is presented. The change of step size μ, at each iteration which is increases or decreases according to the misadaptation degree, is computed by a proportional fuzzy logic controller. As a result the algorithm has very good convergence speed and low steady-state misadjustment. As a measure of the misadaptation degree. The norm of the cross correlation between the estimation error and input signal is used. Simulation results are presented to compare the performance of the FVSS LMS algorithm with the normalized LMS algorithm.
