Graft 共重合物의 光褪色에 關한 硏究(第1報) : 白色度 變化에 對하여 for variance of whiteness

趙慶來 한국의류학회 1983 한국의류학회지 Vol.7 No.1

Variance of whiteness after graft copolymerization of acrylonitrile, methylmethacrylate and acrylamide onto bleached cellulose using Ce(Ⅳ) salt as initiators and the effect of homopolymer on the grafted fibers by photo-irradiation were studied. Also, the development of Yellowing were determined after carbon-arc radiation in a Fade-o-meter. The results were as follows: (1) Variation of whiteness of grafted cellulose fibers were influenced by graft-ratio, Inorganic-Organic Balance (IOB) of functional group in used monomers and adhering homopolymers on the grafed fibers. (2) Yellowing was not affected by the concentration of Ceric Ammonium Nitrate directly during reaction (eg. 0.008>0.006>0.014 M).

IEEE 1588 표준을 지원하는 이기종 분산 네트워크 환경에서 시간 동기화를 위한 PTP 알고리즘 기반의 어플리케이션 프레임워크 개발 기법

조경래 (사)디지털산업정보학회 2013 디지털산업정보학회논문지 Vol.9 No.3

In this paper, We proposed an development method of application framework for using the precision time protocol(PTP) based on physical layer devices to synchronize clocks across a network with IEEE1588 capable devices. The algorithm was not designed as a complete solution across all conditions, but is intended to show the feasibility of such a for the PTP(Precision Time Protocol) based on time synchronization of heterogeneous network between devices that support in IEEE 1588 Standard application framework. With synchronization messages per second, the system was able to accurately synchronize across a single heavily loaded switch. we describes a method of synchronization that provides much more accurate synchronization in systems with larger networks. In this paper, using the IEEE 1588 PTP support for object-oriented modeling techniques through the 'application framework development Development(AFDM)' is proposed. The method described attempts to detect minimum delays, or precision packet probe and packet metrics. The method also takes advantage of the Tablet PC(Primary to Secondary) clock control mechanism to separately control clock rate and time corrections, minimizing overshoot or wild swings in the accuracy of the clock. We verifying the performance of PTP Systems through experiments that proposed method.

The English Absolute monarchy was firmly established with the ascension of Henry Ⅶ who founded Tudor monarchy. In order to establish the Absolute monarchy, though the concentration and institutionalization were necessary, the establishment of financial system, wich precedes them, were more indispensable In England, since the middle Age it had been a custom in peace time that "a king lives on his own, accordingly in peace time, a King's expenditure was met by the revenue of a King's estate. But in the war time or in the emergency, The King asked the permission of financial expenditure to the parliament and the conference of prelates. Win then permission, the King met his war expenses. With the strengthening of the King's authority, he needed more financial expenditure to wield the strong political power. accordingly the British Absolute monarchy enlarged its revenue with the enlargement of King's Authority. As a means of the enlargement of the Royal revenve, Henery Ⅶ Confiscated the estated of the peers who were defeated in the wars of the Roses(1455~1485), and Abolished the feudal peers according to the statue of Liveries, and by establishing special count star chamber, suppressed the remaining Feudal remnants. Not only that, Henry Ⅶ bequeathed much wealth to Henry Ⅶ by Morton's Folk, an obligatory Benevolence. Henry Ⅷ also disbanded monastery and Confiscated its property. In the Elizabethan age, the Absolute Royal Authority was firmly established. In the course of securing Royal wealth, many unreasonable acts and injustices were committed, but Royal revenues were increased and so was Royal expenditure. With the strengthening of the Royal Authority, the war expenses were increased because of the expensionism. With the Royal revenue alone, it couldn't meet the war expenses. So the king asked the parliament for more tariffs and Taxes. In the Course of demanding more resources , there arose conflict between the king and the parliament. This conflict resulted, in the lapse of time, in the establishment of the power of the parliament. The parliament's Repulsion of unfair taxation together with citizen's revolted to the Puritan Revolution under the start monarchy.

The English parliament, an equivalent to the parliament in the modern sense of term, was first emerged in the thirteenth century under the reign of King Edward I(1272-1307) However, in the course of its development for many centuries into the modern version of parliament, the parliament had to go through the trials under the Tudor and the Stuart monarchies, and experience the so called puritan and glorious revolution. The parliament in its early stage mainly acted as the financial supporting and cooperating agency to the Kings Court, however, leter assumed the inherent function of the parliament chacking and balancing king's power. During the reigns of Henry Ⅶ and Henry Ⅷ of the Tudor monarchy, the two king's skillful maneuver of the parliament made it to be named "an obedient parliament" The parliament in the era of Queen Elizabeth I grew remarkably to the extent that it claimed the freedom of press and that it actively performed the parliament's own functions. During the Stuart monarchy the parliament became more active and refused to accept the Theory of Divine Right of Kings claimed by James I. The seventeenth century saw opposition and conflict between the kings party and parliament party, with the consequent victory of the letter the puritan revolution, which was conducive to the establishment of the commonwealth, was caused to heppen. After the puritan revolution Oliver Cromwell's protectorote was once instituted, however with the restration by Charles Ⅱ king power again strengthened and caused another revolution to happen, this glorious revolution provided a momento to firmly establish the parliament's functions in England. Through the glorious revolution, the absolute monarchy was dissolved and the constitutional monarchy under the parliament system was created this system cannot be exactly called "Democratic system", however it provided a stride toward democracy. Thus, the English parliament, which is often referred to as the mother of parliament, has been developed though the puritan revolution and the glorious revolution into the modern parliament.

This research survey is to gain the basic data for student guidance and educational development through the accurate measurement of the Senior College Women's attitude. It is obvious that modern education should be pursued by the scientific and carefully planned educatonal activities and student guidance freed from vague idealism. The education policy, on this account, should be established on the basis of the accurate basic data. In other words, without the accurate basic data, the orginal purpose of education can not be achieved and neither can its plan. The purpose of this research survey is to offer basic data for the improvement of the guidance and education of the College Women by surveying the senior student's attitudes. Accordingly, this suvey's done in the form of a questionnaire, which cousists of 35 items for the views on collegelife, marriage, and society. The survey intended for about 1000 senior students of our university war analysed on the basis of the 662 students' answers to the questionnaires given. This is applicable to the third year research survey analysis of S.M. university's annual research plan and it has some different contents in the questionnaire compared to the previous ones but has the some purpose as they had in the way that they offered the basic data for the educational development and the student guidance. It is quite possible that, in several pears to come, we can survey more desirable educational effect by means of these research survey analysis by comparing and analysing the College Women's attitudes, values, and consciousness. In the point of view above, we hope and expect that this survey can be properly used for the educational development and better guidance for the College Women's lives.

조경래,석줄기 전력전자학회 2005 전력전자학회 논문지 Vol.10 No.5

The overall performance of AC servo system is greatly affected the uncertainties of unpredictable mechanical parameter variations and external load disturbances. To overcome this problem, it is necessary to know different parameters and load disturbances subjected to position/speed control. This paper proposes an on-line identification method of mechanical parameters/load disturbances for AC servo system using support vector regression(SVR). The experimental results demonstrate that the proposed SVR algorithm is appropriate for control of unknown servo systems even with time-varying/nonlinear parameters 서보 시스템의 전체 제어 성능은 기계적 상수의 변화와 부하 토크의 영향을 크게 받는다. 그러므로 서보 시스템의 성능을 향상시키기 위해서는 기계적 상수와 부하 토크를 정확히 알 필요가 있다. 본 논문에서는 Support Vector Regression(SVR)을 이용한 기계적 상수와 부하 토크 추정 알고리즘을 제안한다. 실험 결과는 제안된 SVR 알고리즘이 서보 시스템의 기계적 상수와 부하 토크를 정확하게 추정하고 있음을 보여준다.

Europe Nationalism의 歷史的 考察

趙景來 상명대학교 논문집 1984 상명대학교논문집 Vol.14 No.-

In modern society, nationalism has been much emphasized. As Hans Kohn, the prominent scholar of modem nationalism, said modern nationalism is "one of driving forces of the modem society", and another great scholar of this field, proffessor Carlton Hayes, said that modern nationalism is "the obvious driving movement of the modern and contemporary world". The nationalism was first sprouted in the 17th century England and Landed in Western Europe in the enlightement period of the 18th century and spread all over the Europe in the 19th century and all over the world in the 20th century. The nationalism has been modified in the course of historical stages and has acquired its present various characteristics and dominates the modern society. Therefore it is very difficult to difine the modern nationalism in simple terms. As Hans Kohn said in his book "nationalism" because nationalism is the product of history's vital forces, and so is continuously changing and does not assume a difinite form, but a collective body with various characteristics, it involves multiple significances in it. Of course, the nationalism has many factors in its making, that is, race, language, religion, history, tradition, custom and locality. These are important factors in the making of nationalism, but they are not absolutely indispensable. Generally speaking, in the western societies, nationalism is natural, while in the underdeveloped countries in Asia and Africa, it assumes the form of racial nationalism to oppose the imperialistic aggression of developed countries. Therefore, the modern nationalism has undergone many changed in the course of historical stages and has acquired diverse characteristics. So in order to understand modern nationalism, one should scrutinize each period, each locality and each country. But in this paper, the author has put emphasis on the European nationalism, its origin, character, historical background and developments.

Flow cytometry is an electrical detection system that provides precise and diverse optical properties to cells and micro particles. Flow cytometry, which provides multidimensional information including cell size and granularity through light scattering and fluorescence emission generated by the induction of light of a specific wavelength to the fluorescently treated cells or micro particles, plays an important role in biomedical and biophysical fields. However, it has some drawbacks such as high cost, size of the instrument and limitation in selecting fluorescent dyes. Therefore, in this paper, a low cost compact fluorescent detection system is developed using light-emitting diode and microcontroller. The proposed fluorescence detection system has a replaceable the light source/fluorescence filter/photodetector and constructed by 3D printer, so that the user can design a customized system according to the selected fluorescent dyes. The fluorescence intensity was measured by varying the number of fluorescently labeled cells, and the measured intensities showed a high linearity within the tested concentration ranges. 유동 세포 분석법은 세포나 입자에 대하여 정밀하고 다양한 광학적 특성을 제공해주는 전기적 탐지 기술이다. 형광 처리된 세포나 미립자에 특정한 파장의 빛을 가함으로써 발생 되는 광 산란과 형광 방출을 통해 세포의 크기와 입상도를 포함한 다차원적인 정보를 제공해주는 유동 세포 분석법은 생체 의학 분야 또는 생물 물리학 분야에서 중요한 역할을 수행한다. 그러나 유동 세포 분석법은 고가이며 장비 설치에 있어 적절한 공간이 필요하고 형광 염료 선택에 제한적이라는 단점을 가지고 있다. 따라서 본 논문에서는, 상용화된 유동 세포 분석에 사용되는 고가의 레이저와 운영시스템 대신 발광 다이오드, 마이크로 컨트롤러와 광 검출기를 사용한 저가의 형광세포 측정 시스템을 개발하여 사용자가 원하는 형광 염료에 대한 자유도를 높였다. 또한, 3D 프린터를 사용하여 모듈별 소형화 및 경량화를 통한 사용자 맞춤형 제작이 가능하도록 하였다. 그 결과, 형광처리 한 세포의 양에 변화를 주어 발광도를 측정하였을 때, 높은 선형성이 보임을 확인할 수 있었다.
