According to the modernization of mathematics education, new abstract concepts such as the concept of sets are introduced in many fields of it. The purpose of this thesis is to adopt the concept of sets to "probability" which is included in the curriculum of high school mathematics education. The considerations of the preceding chapter III, and their obvious generalizations to more complicated experiments, justify the conclusion that probability theory consists of the study of sets. An event is a set, its opposite event is the complementary set; mutually exclusive events are disjoint sets, and an event consisting of the simultaneous occurrence of two other events is a sets obtained by intersecting two other sets it is clear how this glossary, translating physical terminology into set theoretic terminology, may be continued. Furthermore, the important theorems of probability; Additional theorem, multiplication theorem, their applications and so on, are proved by the technical operations of sets. Thinking of the mathematics education introduced by the concept of sets is very important in future.

직류 전기아크로를 제어하기 위한 전원장치로서의 AC/DC 공진형 컨버터

유병우,최재호,JaanJarvik 전력전자학회 2003 전력전자학회 논문지 Vol.8 No.1

When solving the problems of electric power quality the converters with high power factor are useful for the DC arc furnace power supply. In this paper, resonant converters of 50(60) Hz AC to DC are described, where in each period of network voltage the capacitor and inductor of an oscillatory circuit are switched from series into parallel and vice versa parametrically. The duration of series and parallel connection and also the transformation ratio are dependent on load. Parallel oscillatory circuit restricts the short circuit current. These converters have high power factor from no-load to short-circuit and fit very well to supply arc furnaces. 전력품질 문제를 해결할 때 직류전기아크로의 전원장치로서 높은 역률을 갖는 컨버터가 요구된다. 본 논문에서는 계통전압의 각 주기에서 커패시터와 인덕터의 공진회로가 부하변수에 따라서 직렬연결상태에서 병렬연결상태로, 혹은 그 반대로 전환하면서 고역률을 유지하는 50(60)Hz 교류에서 직류로 변환하는 공진형컨버터가 묘사된다. 직렬연결과 병렬연결의 기간과 변환비는 부하에 따라서 결정되며 병렬 공진회로는 단락회로를 제한한다. 이 공진형컨버터는 무부하에서 단락회로의 범위까지 높은 역률을 가지며 아크로에 전원공급을 하는 장치로 매우 적당하다.

Phenylpropanolamine 복용후 발생한 뇌경색증 1 예

Phenylpropanolamine, a sympathomimetic amine structrally related to ephedrine and amphetamine, is commonly used as a anorectic agent and nasal decongestant. It releases noradrenaline from sympathetic nerve endings and gives a direct stimulation of alpha-adrenoreceptors in blood-vessels. It causes severe hypertension, cerebral hemorrhage, psychosis and central nervous system stimulntion. But the cases of cerebral infarction are very rare and not well known of it's mechanism. But several studies and clinical review suggest that phenylpropanolamine causes vascular spasm and fibrinoid necrosis result in tissue ischemia. We experienced a case of cerebral infarction in a healthy 18-year old woman who had taken 8 tablets of anorectic pill containing phenylpropanolamine 75mg and caffeine 200mg. She had no history of hypertension or drug abuse. She presented stuporous mental status, convulsion and right sided hemiparesis. And we found cerebral infarction in pons and left occipital lobe on brain MRI.

Although it can be said that the role of language is communicative, when one regards language in a wider perspective, its role carries a grater meaning. Language embodies cultural aspects as well as a great many things not easily verifiable. This is particularly apparent in Christian language. The language of Christians has generally been examined in its application, or in the principles governing its practies. There contains, however, a deeper hidden significance that must be dedicatedly examined, especially in today's ever changing world. While there has recently been an increase in the attention given to linguistic studies and the acknowledgement of their importance, there has been a relative decrease in the sense of a deeper insight or a knowledge of correct usage of language. There has been a cease in true communication: hatred and conflict are the chief antagonists. That is why issues such as the phenomenon of social diseases, the decline of ethical awareness and the breakdown of ethics are raised. But ultimately there lacks a language based on true Christian spirit. Ever since the Tower of Babel, we humans surfer from linguistic confusion through lack of communication, and not only has the extent of understanding been dramatically reduced. But we are also faced with the impossibility of practical communication. This does not confine itself to a superficial confusion in language, for with it comes a confusion in its very ideology and manner of expression. Language is an efficient way of expressing and individual's values and views on the world. It can be said that language is clearly charged with a value-sense and a world-sense. In other world, one's inner self is revealed through language. However, the methods of language usage or other such choices are not important. What is important is the value-sense hidden inside the language, just as the world-sense of the individual in question is more important than any outwardly visible action. Christian language assumes a greater importance in this way, and is without doubt the only type of language that can cure this confused and corrupt world. However, this truly important aspect is invariably overlooked and fails to get due attention. This is not only because of the Original Sin of human beings which emphasizes an external faith while neglecting the inner faith, but also because of narrowness of humans' capability of understanding. A further part is played by a misdiagnosis and false prescription for these problems. Although people initiate various methods and attempt various endeavors to free themselves from the yoke of corruption and irregularities in modem society, they are in fact failing to establish an important and fundamental world-sense for themselves. The fulfillment of his fundamental world-sense can be found within Christian language. What is the most striking characteristic of the language of Christians? Is it that we can only utter words we think good and righteous? Although we talk about proper functions and counter-functions of language, we are ignorant of the fundamental aspects of language. This is also true of what we understand of positive and negative aspects of language. So then what really is most important about Christian language? It is the truthfulness of the value-sense and the world-sense therein contained. The significance of Christian language cannot be recognized in isolation. This is true not only of language but of everything. The significance of everything in Creation is recognized only in respect to its relation to God. Christian language is important not because it is noble or because it is self-worth, but because it reveals things in their relation to God. That is to say that purpose of language is recognized only when it is used in the context of God's value-sense and world-sense. The solution to how language is to be used in this world of ours is not found in polite words or in the mildness of non-injurious words, but can be discovered where the fundamental spirit has its foundation. Therefore the restoration of language and the establishment of the right view of language is in fact a restoration of this fundamental spirit and the establishment of the world-sense. Many people talk about the need for a greater effort in educating the human character and promoting morals, but this is no more than a superficial solution that does not reach the core of the problem. What can be done to solve the problems that we face today? We must restore a Biblical value-sense an use language appropriate to this value-sense. This is only possible when a language which allows us to live a living language, an a language has the capability of being wholly governed by the Holy Spirit, is restored. How can these languages be restored? When the dialogue between ourselves and God is restored, the confusions inherent in language will disappear and true communication can be reestablished. This research paper aims to deal with the foundations of Christian language with that very objective, and to deduce the ethics of Christian language based on those foundations. It is hoped that the true nature of the language of Christians will be revealed through this attempt.
