效果的인 數學科 學習指導 方法에 對한 考察 : 指導形態를 中心으로
남규창 安東大學 1981 安東大學 論文集 Vol.3 No.1
A teaching method should be based on developing independent judgments of students without recourse to the repetition drill but with vivid experience and insights. What gives an influence on the type of teaching is the character of the course and the subjects of teaching. The type of teaching will vary according to the character of the course to study. As the subjects of teaching are composed of individuals with various indiosyncracies, an effective method which considers the individual`s character should be used. The purpose of this paper is to search for an effective teaching method of mathematics in the elementary and secondary schools through analyzing and estimating the various methods like the lecture-centered teaching method, the student-centered teaching method, and the eclectic method. After applying these methods to actual classes, the writer has reached the following conclusions. The points which should be considered in the teaching methods of mathematics in the secondar schools may be summarized as the followings. 1) The eclectic method using both the lecture-centered and the student-centered teaching method is desirable for the low-grade students who lack fundamental knowledge and skills about mathematics. 2) The student-centered method is better than the lecture-centered method for the high-grade students who have plenty of fundamental knowledge and skills about mathematics.

By the examiation, assumption, and frequency table, the external forms can be realized, but the charcteristic of distribution can not be described in number. There are average, dispersion, shrewdness, kurtosis and moment in describing the characteristic of dictribution in number. The statistic should indicate the characteristic of statistic group best and also it should be reliable and objective as well. The statistic average is helpful in approximating the change in the future. The statistic average is selected at random out of the statistic group as a part of sample and this should be of good representative. When we make a decision on the population in terms of statistic average obtained from the examination of sample, it is natural that there should be some mistakes occuned. And it is very important that the population should be examined exactly. In concision, 1) As we see in Table 3, the relative frequency of quartile mean about mean is more than 99.5%. 2) According as the number of statistic materials is increased, the relative frequency becomes large and the absolute error becomes little. 3) This can be utilized as a basis of getting the other statistic value.

Today with the keen development of science the basic subject of mathematics is advancing quickly too so that effective guidance is necessary. Accordingly for effective guidance in mathematics practice, purpose, content and basic principles must be established and after the examination of an adequate text guidance must be given with various techniques. Accordingly it will be more effective and give more efficient practive if, among the exixting forms which are able to guide with emphasis on the student, teacher, a combination of both, simple test methods, the most effective method is employed, namely, with the teacher central to develop the practice in accordance with the purpose. To achieve this, guidance must be that which involves text research and enthusiasm which does not avoid the focus on practice.

A rational number can produce a variety of fractions, which is all equivalence. And any fraction can be changed into equivalence fraction by multiplying the dinomiator and numerator by the some figures, A certain fraction reverses this process; that is, by Dividing the denominator and numerator into same figures, a fraction can be reduced to its lower terms. A fraction which has no common divisor(the highest common divisor l) of the denominator and numerator is called the irreducible fraction and any fraction can be reduced to its lower terms by the highest common divisor, when the two fractions are reduced to common denominator, they are equivalence, one of the two is high, or the other is low For the comparison of those two fractions. it is convenient for the two denominators to be reduced to common denominator by the least common multiple. When the denominator is factorized in prime factors, and reduced to common denominator by the least common multiple of the deniminator, the figures which should be multiplied remain un done. Another way to realize whether two fractions are equivalence or not is to multiply denominator by numerator roversely and compare its result: if a/b and c/d are equivalence, they prove a×b= b×c. Lastly, we realized that no matter how narrow the difference between the two rational numbers there always exists the third rational number between them. It means that we do not see the number which comes before and after any rational number different from the natural.

代表値에 對한 小考 : A Study on the Teaching of Deductive Inference in the Education of Arithmetic
남규창 安東敎育大學 1975 論文集 Vol.8 No.1
Mean is different from average by the method of culculation a little. As it has a changeable value, it does not metter whichever methods are used. In fact, between the average of sum and that of frequency table, only 0.5 % of error was admitted.

Some Characterizations on Contact CR-Product of a Sasakian Manifold
남규창 安東大學 1985 安東大學 論文集 Vol.7 No.1
최근들어 부분다양체론중 불변부분다양체, 반불변부분다양체, Generic부분다양체의 일반적인 확장인 CR-부분다양체에 대한 연구가 활발히 진행되어져 왔다. 한편 B.Y. Chen(1982)은 Kahler다양체의 CR-부분다양체가 CR-적이 될 필요충분조건을 연구했다. 본 논문은 Sasakian다양체상에서 접촉 CR-적을 정의하고 Sasakian다양체의 접촉 CR-부분다양체가 접촉 CR-적이 될 필요충분조건을 연구했다.

A Capacitance Measuring Technique By Time Constant
Nam, G. C.,Chang, I. L. 安東大學 1988 安東大學 論文集 Vol.10 No.1
RC회로의 충전전압은 V(t)=E(1-exp(-(1)/(RC)t))로 표시된다. 본 연구에서는 시정수 T=RC이므로 시정수를 측정함으로써 Capacitance 를 계산 할 수 있음에 착안하여 이를 측정하기 위한 전자회로를 설계하고 Oscilloscope로 측정실험하였다. The charging voltage for RC network is V(t)=E(1-exp(-(1)/(RC)t)). In this paper, we presented a method for obtaining capacitance by measuring the time constant. Therefore, we designed electronic circuit for measuring capacitance and displayed on an oscilloscope input charging curve and time constant pulse.

A Note on Von Neumann Regular Rings
Nam, Gyu Chang 安東大學 1983 安東大學 論文集 Vol.5 No.1
R. Yue Chi Ming은 1980년에 정칙환과 WP-환과의 관계를 조사하였다. 그리고 1983년에는 CF-injectivity, MP-injectivity를 소개하였으며 정칙환과의 관계를 연구하였다. 본 논문에서는 p-injectivity를 일반화한 CF-injectivity를 도입하여 WCF-환을 정의하고 정칙환과 WCF-환과의 관계를 조사하였다. Non-trivial central idempotent를 포함하는 WCF-환은 정칙환이며, 특히 WCF-환에서 (1) 유한차원, (2)반단순환, (3)Goldie환이라는 것은 동치임을 밝혔다.
