본 연구는 청소년 도박행동 실태를 파악하고, 도박행동 경험 유무에 따른 청소년의 특성, 비합리적 도박신념, 스트레스의 차이를 파악하며, 청소년의 도박행동에 영향을 미치는 요인을 확인하고자 시도된 서술적 조사연구이다. 연구대상자는 J도내 4개 고등학교 학생 296명을 대상으로, 2017년 11월 9일부터 15일에 걸쳐 자가보고식 설문조사를 실시하였으며, 수집된 자료는 SPSS 21.0 프로그램을 이용하여 분석하였다. 연구 결과, 대상자 중 최소 0.3%에서 최대 29.1%까지 도박경험이 있는 것으로 나타났다. 대상자의 비합리적 도박신념은 평균 20.72±8.43점, 스트레스는 평균 88.09±28.70점이었다. 도박행동 경험 유무는 성별, 학년, 친구도박행동, 아버지 도박행동 및 자아 스트레스의 정도에 따라 차이가 있었다. 도박행동에는 친구도박행동이 가장 크게 영향을 미치는 요인이었으며, 친구도박행동이 월1회 이상인 경우가 월1회 미만인 경우보다 1.86배 정도 도박행동 가능성이 높은 것으로 나타났고, 본 연구모형의 설명력은 41.3%이었다. 본 연구는 청소년 도박문제를 감소시키고 또래집단 환경의 변화와 도박중독의 폐해와 심각성을 알릴 수 있도록 주기적인 도박문제 예방교육이 시행되어야 할 필요성을 제기하였다는데 의의가 있다. The purpose of this study is to investigate current status of adolescents gambling behavior and to investigate whether irrational gambling beliefs and stresses affect adolescents gambling behaviors. The study examined 296 students who are students in 4 high schools in J-Do. The data was collected from Nov 9 to Nov 15, 2017 using self-report questionnaires. The data were analyzed by the SPSS WIN 21.0 Statistics. Results: It was showed that at least 0.3% to 29.1% of the subjects had gambling experience. The Irrational gambling belief 20.72 points on average, stress was average 88.09 points. Gambling behavior with or without gambling behaviors showed that gender, grade, friend gambling behavior, father gambling behavior, and self-stress affected gambling behavior. For regression analysis, friend gambling behavior were proven to have an significant impact on adolescents gambling behavior. It was found that the probability of gambling behavior was 1.86 times higher than that of less than once a month when the friend gambling behavior was more than once a month. The variance accounted for adolescent gambling behavior was found to be 41.3%. This study is significant that in order to decrease adolescents gambling problem and inform the change of the peer group environment and the harmfulness and seriousness of gambling addition, periodic gambling problem prevention education should be implemented.

This study examined the effect on the education of scientific attitude in the process of primary school education by application of STS teaching-learning method with an unit of 6th grade in primary school environmental pollution and nature conservation. The attitude relating science education, on the other side, is classified into 4 parts; attitude for science, social meaning of science, attitude for science subject and scientific attitude. The study of sexual difference on the above points was examined too. The results was taken as follows. 1. STS Teaching-learning method gives positive effect of the education of scientific attitude more than traditional teaching method, especially on the point of the attitude of science lesson and scientific attitude. 2. STS education has an great influence on the social meaning of the scientific attitude relating science education; investment in science, relation with society, solving social problem, contribution to development of society and technology. 3. STS teaching-learning is thought to be the learning that is more effective for boy than girl. In conclusion The STS Teaching-learning method is preferable in order to increase the scientific attitude of the elementary school students.

自動機械管理上에서 Queues理論의 應用

This paper proposes to indicate with logical analysis a mathematical model to various phenomena arising out of planning and management. I have also tried, with regard to the management of automatic machines, to show different ways of applying the theory of queues in the case of M/M/1 type, and extending the idea, in the case of M/M/s type, thus comparing with many examples various degress of efficiency.

材料疲勞破壞에 對한 數學的 model 硏究

崔春鎬 漢陽大學校 1972 論文集 Vol.6 No.-

Very recently, the theory of probability has been applied in the field of engineering problems. In particular, the problem to decide reasonable maintainability to the system engineering is the one of the most important problems to design structures. To study maintainability, we have two ways to approach to the study of fatigue crack, one is experimental research and the other is analytic method. The experimental method has developed very rapidly. N. E. Frost, A. K. Head, D. A. Dugdale's achivements are distinguishable. In this paper, I study the maintainability by analytic method with a few hypotheses and construct a mathematical model with the theory of birth and death process to the cracks which yield by weight given in the objects. General formulars thus induced are analysed by Laplace transformation with the given assumptions.

環境汚染物質의 許容基準値 決定에 對한 統計學的인 考察

崔春鎬 漢陽大學校 環境科學硏究所 1983 環境科學論文集 Vol.4 No.-

最近 環境汚染問題의 重大性에 따라 여러가지 汚染物質의 許容基準値 決定問題도 多角度로 考察되고 있다. 一般的으로 汚染物質의 測定値는 環境條件의 差異, 偶然的인 誤差等으로 이런 資料에 의하여 處理하는 데는 統計學과 密接한 關係가 있다. 그러나 統計學的인 側面에 대한 關心이 적고 處理方法의 開發 또한 不足한 實情이다. 따라서 이 論文에서는 汚染物質의 許容基準値決定에 測定値를 이용할 때 統計學을 應用하는 一部分을 考察한 것이다. In recent years, as the problems of environmental pollution are becoming increasingly more serious, many studies have been made on how to determine the allowable standard values of pollutants. On the whole, data on pollutants, when they are processend, have close connection with statistics because of differences in the conditions of the environment and eventual errors. But the reality of the matter is that little attention has been given to the statistical aspect of the problem. At the same time, there is much room for further development in the processing method also. Therefore this paper hopes to show how to apply statistics when using data to determine the allowable standard values of pollutants.

통계적발취검사법의 위상적인 一般化硏究

최춘호,김용운 漢陽大學校 1979 論文集 Vol.13 No.-

It is well known that the limit theorems of probability theory, which previously dealt primarily with the theory of summation of independent Radom theorems, have been extended to the theory of stochastic process. The authors attempt a new approach to limit theorems which can be used for many topological spaces in which in general no compleate metric exists. The authors introduced almost convergent topology in the spaces of 1st kind of discontinuous function and generalized the above mentioned results.

計量拔取檢査實施上의 理論硏究

崔春鎬 漢陽大學校 1979 論文集 Vol.13 No.-

The application of statistical theory to sampling inspection by variables was first initiated by Dodge-Roming and later developed further by W.A. Wallis and A.H. Bowker. Based on the test of hypothesis, this theory lays too much emphasis on the construction of a mathematical theory. As a result, the practical application of this theory to curreut industrial conditions runs into many difficulties. The necessity of another practical theory which combines theory with practicality needs no special mention here. In this paper I introduced operating characteristic coustant into sampling inspection by variables in order for it to suit the existing conditions in industries.

Extension of Game solution by G. W. Brown

Choi,Chun Ho 漢陽大學校 1971 論文集 Vol.4 No.-

Game 値存在에 대한 證明은 Game理論의 基本事項이며 Game理論의 展開도 이것에 의하여 成立된다고 할 수 있다. 元來 Game理論 自體가 代數學的인 性格을 갖고 있으므로 Brouwer는 1950年 不動點定理를 使用해서 Game 値存在를 證明하였고, Nash는 convex set의 分離定理를 利用해서 證明하였다. 그러나 G.W.Brown은 이것을 解釋的인 方法 卽 微分方程式을 利用하여 간결하게 證明하였다. 卽 Game matrix인 A??(ij=1,2......m)인 경우의 zero-sum two person Game 의 min-max 定理를 證明하였다. 이 論文에서는 이 方法을 擴張하고서 §4,5,6에서 證明한 것과 같이 일반적인 Game matrix인 A??(i=1,2......p, j=1,2.....q)일 때에 대하여 證明하였으며, 몇가지 性質에 대하여도 付言한 것이다.
