단순지지된 슬래브교량의 간편방법에 의한 해석

신철호,한봉구 서울産業大學校 2005 논문집 Vol.54 No.2

The simple supported slab bridges are analyzed by the specially orthotropic laminates theory. This method, however, may be too difficult for some practising engineers. In this paper, the result of analysis for such plate by means of the beam theory with unit width is reported. By using the "correction factor", the accurate solution for the plate can be obtained by the beam theory. The result of this paper can be used for reinforced concrete slab bridges analysis by the engineers with undergraduate study in near future

With a view to examining the habit and method in which old people maintain and improve their health, we consulted 551 men and 444 women who were over 65 years old, and concluded as follows: 1. Habit of eating It's been revealed that most of the old people keep a regular eating hour, control the quantity of meal or eat a little food, and prefer vegetables to meat. 2. Mental health Old people feel the necessity for mental health and most of them (about 80%) keep good mental health without becoming pessimistic. Their chief concenrs have turned out to be about their sons and daughters and their own health and finance. 3. Managing Good Health It has been revelaed that old people do not possess any special kind of secret to keep good health but taking plenty of rest, regular meal, and proper exercise, and many of them (about 60%) have been shown to eat invigorant food that they can easily get around their living area. 4. Physical Functions It has been revealed that many old people are conscious of some symptoms about their parts of body and about to percent of them suffers from neuralgia. Some measures like medical aid especially for old people need to be taken as soon as possible. As we have found that the health-keeping method of old people consists plenty of rest, proper exercise, and appropriate nutrition, we can conclude that the recreatonal and culture facilities and programs for keeping old people in good health should be developed. It is also necessary to study food that contribute to their health and develop ways to get rid of the stresses to which they are exposed in their daily life. Presides, it is natural that government found an administrative department to deal with these matters effectively.

신재옥,구경완,홍봉식 충남대학교 공업교육연구소 1986 論文集 Vol.8 No.3

Dry Oxidation and Wet Oxidation process of (100) P-type silicon have been examined experimentally. The oxidation temperature was 1,100℃ and Oxygen flow rate was changed from 200 cc/min to 1000 cc/min. From the experimental measurements, moxid₄atmon temperature, time and Oxygen flow rate have been graphed for oxide layer 0.24 μ∼0.9 μ in thickness. The optimum value of O₂ flow rate has been found to be 1.4 cm/sec. The quality of the grown oxide layer has been investigated in terms of the dielectric constant, breakdown voltage, fixed surface charge density(Ωf), and mobile ion charge density(Ωm/g). From these measurements, it is concluded that the quality of the oxide layer is sufficient to expect the normal operation of MOS transistors.

The diagnosis and monitoring system of abnormal cutting condition is necessary to realize precision machining process and factory automation, which are final goal of metal cutting. In order to develop this system, the image processing technique has been investigated in machining process. In this paper, the measurement system of tool wear using computer vision is designed to detect the wear pattern by non-contact and direct method and get the realiable wear information about cutting tool. We measured the area of the side and front part of the diamond core drill which is used in 40 kHz ultrasonic vibration machine.

J.-J. Rousseau의 자서전 서술방식에 관하여 : 언술행위 이론을 중심으로

이신철,박종탁,양인봉 東亞大學校 大學院 1990 大學院論文集 Vol.15 No.-

En nous situant au discours vu dans la perspective de l'ennonciation, nous nous proposons, dans notre etude, d'analyser les quelques phrases ou le sujet evoque sa naissance et les relations qu'elle fait entre lui et ses parents. Pour cela, nous nous servons volontiers de procedures linguistiques qui dependent de la notion d'enonciation. A travers la tension entre les protagonistes, telle qu'au moment de l'ecriture le narrateur la restitue, nous pouvons constater que l'ambivalance du pere se refletent dans la double attitude de son fils : au-dela de la tendresse filiale apparaissent l'accusation et la haine, c'est ce qui nous amene donc a croire que c'est le d'esir inconscient du narrateur qui a distribue les roles a l'un rt a l'autre. en nous referant a l'opposition entre temps histor que et temps du discours, nous constatons aussi que le narrateur rapporte un enenement historique, mais en realite cette objectivite n'est qu' apparente. ciest parce que l'evocation subite de la mort de son pere revele la vengeance secrete du narrateur. La conclusions que nous pouvons tirer de notre etude, c'est que notre etude n'est qu'une approche pour atteindre les traces du sujet inconscient qui affleure dans les textes autobiographiques.

김용태,신봉숙 한국수학교육학회 2003 初等 數學敎育 Vol.7 No.1

In late 19C, German mathematician Felix Klein declaired "Erlangen program" to reform mathematics education in Germany. The main ideas of "Erlangen program" contain the importance of instructing the concepts of functions and groups in school mathematics. After one century from that time, the importance of concepts of groups revived by Bourbaki in the sense of the algebraic structure which is the most important structure among three structures of mathematics - algebraic structure, ordered structure and topological structure. Since then, many mathematicians and mathematics educators devoted to work with the concepts of group for school mathematics. This movement landed on Korea in 21C, and now, the concepts of groups appeared in element mathematics text as plane rigid motion. In this paper, we state the rigid motions centered the symmetry - an important notion in group theory, then summarize the results obtained from some classroom activities. After that, we discuss the responses of children to concepts of groups.

전자패키지 μBGA 무연솔더와 무전해 Ni 도금층의 계면 접합특성

The morphology and thermal stability of the interfacial phases in the joints between Pb-free solder (Sn3.5Ag0.7Cu) and electroless Ni-P(14at%P) and electrolytic Ni under bumper metallizations (UBM) were investigated as a function of solid state aging. Samples were prepared by reflowing at 250℃, N_(2) atmosphere and aging in the range of 125 to 170℃ for up to 1000h. After reflow, the interfacial intermetallic compound(IMC) was mostly Ni_(3)Sn_(4) in the electrolytic Ni/solder joint. After relatively short aging time, the interfacial IMC on electrolytic Ni layer developed into the dual layer structure of Ni_(3)Sn_(4)(bottom) and Cu_(6)Sn_(5)(top). But IMC on electroless Ni-P layer were Cu_(6)Sn_(5) and changed into the dual structure only after long aging time of 1000h. The growth rate of IMC with aing was higher on electrolytic Ni layer than on electroless Ni-P. The different behavior of electroless Ni-P/SAC joint came from Ni_(3)P formation between IMC and electroless Ni-P layer which retards interfacial reaction through reducing the diffusion of Ni and Sn. The thickness of Ni_(3)P layer was propositional to that of IMC. For longer aging time, NiSnP layer was found at the interface between IMC and Ni_(3)P layer. Interestingly, in spite of low consumption rate of electroless Ni-P than electorlytic Ni layer by suppressing IMC growth, the interface of Ni-P/IMC was locally hollowed by the accelerated reaction of the Ni-P layer through local thickness reduction of Ni_(3)P and NiSnP layers. This reduced the effective remaining thickness of Ni-P layer.
