日本腦炎 virus의 토끼섬유종에 (纖維腫) 대한 억제작용 (抑制作用)
백남은(白南垠),이호왕(李鎬汪) 대한바이러스학회 1972 Journal of Bacteriology and Virology Vol.2 No.1
Certain viruses have been shown to parasitize tumors and cause necrosis of the tumors. It has also been demonstrated that virus III causes suppression or early regression of the rabbit fibroma. The present paper describes the results of a study on the oncolytic action of Japanese encephalitis virus (JEV) against the rabbit fibroma caused by virus. 1. JEV exerted some influences on the fibroma formation of rabbit and showed remarkable oncolytic action. In the control group the fibroma took a course for four to five weeks but was cured after only two weeks in the inoculated one with JEV. 2 In the case where inoculated JEV intramuscularly in day 0 after inoculation with fibroma virus the oncolytic action appeared severer than in the case of day 3 or day 5. And there was no effect in the case injected with heat inactivated JEV. 3. In the case injecting the JEV intravenously or intracutaneously there was also same effect as in the intramuscular injection. It could also confirm that once recovered from rabbit fibroma there was no production of it due to the aquirement of immunity though reinjected the fibroma virus. 4. The experimental group which inoculated a plenty of JEV to the fibroma mass directly showed the rapid recovery as compared with the non-inoculated one. And in the case injecting intramus cularly the JEV in the period of 24 hours after inoculation of fibroma virus it was capable of the detection of plentiful JEV from fibroma mass even in the course of day 10.

It is possible to solve the four species; addition, subtraction, multiplication and division in allrational numbers, because the above four species are not solyed with natural numbers. If there is problem in the four species; subtraction, multiplication and division, it is satis factory with all rational number. In the problem of the continuous number, it is not enough to solve the algebraical eguation χ^2+1=0 with the actual number Gauss found the complex number style expanding the actual number style. Based on this result, an algebracial equation of n order had root of n number certainly. This is basic theorem of algebra and the complex number was expressed with vector.

Born in France in 1814, Catalan was a university professor of mathematics in his manhood and a member of the Belgian Royal Academy. Catalan wrote about 400 pieces of treatises in the field of mathematics, and he won the Belgian Academy prize for "on the Transformation of Variables on the Multiplex Integral Calculus" in 1840. He showed a distinctive quality in the interpreting "Solution d'um Problemede Probabilite Relatif au jeu de vencontre" of his many treatises, using definite difference equation.

The definition of integral is that finite function for finite interval could be integrated. Next when in spite of heing finite in interval integral of infinite funcfcon and integral introducing integral concepts is distinguished with general integral, it is defined as transcase integral, extensive integral and pseudo integral. Though general integral is defined as a utmost limits of Rieman sum, pseudo integral is defined as a utmost limits of general integral

Aggregate consists of such things as numbers points, functions, letters, etc. In general, any kinds of things whch can be the objects for logical consideraton are thought to be the things which compose aggregate. In mathematics, however, as strictness is important, the group of things which are called as aggregate must be the definite things whether they are included in the group of the things on not. also, I described the notations of aggregate, equality of aggregate, suf-aggregate etc. in details.

Of the general prob1ems concerning teaching mathematics, first, I described the general features, second, the particulars, and this time I will describe such and such parents are disired to cooperate with the teaching students at school. A teacher should have good character, sufficient knowledge of his major field, and firm view-point of eduation, of course, and it is most important how the parents cooperate with teacher's teaching for their student's better 1earning. There are many technical problems. A teacher of mathematics should not evaluate his students with zero, and the most important point is the process from which a conclusion is drawn out. The teacher had better give some points to a student required some answers as far as he knows if he cannot solve a question completely. On the contrary a teacher should be strict in evaluating a student with fu1l marks. Parents must not be impatient and they are required to treat their sudent with Jong-sightedness, and they should desert the so-called parent's disposition. There is a famous psychologist's saying,“Praise first and b1ame second.”
