Many a man has a tendency to regard the probability as a peculiar field of mathematics. The Object of probability is not Numbers or figures in Algebra or Geometry, but it seems to be a study freating Something like probable called, "phenomena decided by an Accident." But this is not except Axiomatically modern Mathematics Based on reflection of practical lectures with a concept of Probability, here is a Modernized plon of the Theory a Summary.

On Lie-algebras and Semi-simple Lie-algebras
李孝泰,金冕鎬 慶北工業專門大學 1978 論文集 Vol.15 No.-
In this paper, basic facts on Lie algebras and semi-simple Lie algebras are studied. The results obtained here will be applicable for claracterizing the structure of semi-simple Lie algebras.
On cosymplectic Bochner recurrent manifods admitting concurrent or parallel vector fields
Lee, Hyo Tae,Park, Ha Yong 慶北工業專門大學 1981 論文集 Vol.18 No.-
We defined a cosymplectic Bochner recurrent manifold[6]. The present paper is concerned with the case that the cosymplectic Bochner recurrent manifold admits concurrent or parallel vector fields. We show that if a cosymplectic Bochner recurrent manifold is a Ricci recurrent space and admits concurrent vector fields ??, then ??=-α(2n+1) or the manifold is flat. And we show that if a cosymplectic Bochner recurrent manifold is a Ricci recurrent space and admits a parallel vector field ??, then ?? is orthogonal to the recurrence vector ?? or the manifold is flat.

It is very interesting and useful to investigate the properties of figures on reduced drowing. In general we use the reduced scales as some constants. In the present paper the authors investigate the functional reduced scales as, suitable function of the length from origin. At first, we introduce the functional reduced scale on Cartesian coodinate plane, and next we study on the polar coodinate plane.
