舊韓末 嶺南儒林의 開化敎育觀 硏究

이동기 한국교육철학회 1997 교육철학 Vol.15 No.-

In the final term of Old Korea, that is, from late in the 19th century to early 20th century, Chosun was in the midst of a great social upheaval. To copy with the internal contradictions and the external challenge from the West, the intellectuals of Chosun had tried every means possible. On the one hand, some had trid to keep the traditional Confucian ideology and social system, on the other hand, others had tried to accept the western new knowledgy and technology. This contradictory movement had formed the dual structure of "resistane and acceptance". This dual structure had developed into right-defending and the wrong-expelling, and into the enlightenment movement. The Confucian scholars of Yeungnam District could be classified into two groups; one group was composed of the conservative scholars whose way for overcoming the national crisis was to renew and reconstruct the traditional Confucian ideology and expel the westen ideology and culture, the other group was composed of the progressive scholars whose way for getting over the national crisis was to accept the western new technology positively. The leading scholar of the latter group was Ryu In-sik whose pen-name was Dong-san. Dong-san maintained that the traditional-out of date-ideology should be rooted up Confucianism and the western new technology should be accepted as the basic theory of the national enlightenment and development. To realize these aims, Dong-san emphasized the need of new education and founded the Cooperative School for accepting the western new knowledge and technoloy. To sum up, the above-mentioned dual structure of "resistance and acceptance" had become the basic principle of coping with the national crsis and become the blasting fuse of the independence movement and the resistance movement aganinst Japan.

대학 운동부 지도자의 지도경험과 교육적 의미 탐색

김동기(Kim, Dong?Kee) 한국체육과학회 2018 한국체육과학회지 Vol.27 No.1

This study suggested the categorization of the notion, the factors and process of axial coding deducted through grounded approach as a research to verify the instruction experiences and educational significance of survey of university athletic club coaches. As a result of open coding, first, a total of 135 terms, 22 subcategories, and 11 upper categories were suggested. Second, as a result of axial coding, 6 paradigms were composed in the instruction experiences and education significance of university athletic club coaches. As for the casual conditions, university coach life, becoming a coach after retirement, and charm of the job were suggested, and as to the situational context, it was deducted as the relation formation with athletic students. Furthermore, as a central phenomenon, the professional instruction method was shown. In this connection, instruction contents and experiences are suggested as an interventional condition. As for the interaction, such as communications and successful instructors are found as a strategy of interaction. As a result of this process, it was found that athletic club coaches acquire the educational contents know-how and methods applicable for each level for themselves. Third, as selective coding, the outline of a story about the instruction method specialization process of athletic club coaches were performed, and the core categories were discovered in this process. It was understood that through not only improvement of educational contents but also instruction methods and various curricula about the specialization process, the individual “Know-how” of a coach, namely, empirical knowledge is naturally accumulated.

In this process, EBPA NN was constituted to an output error value of an IM and conspired an input and output. The performance of the self-tuning controller is compared with that of the PH) controller tuned by conventional method (Ziehler-Nichols). The effectiveness of the proposed control method is verified thought the Matlab Simulink and experimental results.

齒科用 Ag-Pd-Cu 3元合金 및 Au添加合金의 時效硬化特性

이기대,곽동주 대구보건대학 1999 대구보건대학 論文集 Vol.19 No.-

The Ag-Pd-Cu alloys containing a small amount of Au is commonly used for dental purposes, because this alloy is cheaper than Au-base alloys for clinical use. However, the most important characteristic of this alloy is age-hardenability, which is not exhibited by other Ag-base dental alloys. The specimens used were Ag-Pd-Cu ternary alloys and Au addition alloy. These alloys were melted and casted by induction electric furnace and centrifugal casting machine in Ar atmosphere. These specimens were solution treated for 2hr at 800% and were then quenched into iced water, and aged at 350~550℃. Age-hardening characteristics of the small Au-containing Ag-Pd-Cu dental alloys were investigated by means of metallurgical microstructures, X-ray diffraction and electron microscope observations, energy dispersed spectra and electron probe microanalysis. Principal results are as follows : The case of hardening in stage Ⅰ was due to the formation of the L1o type face-centered tetragonal PdCu-ordered phase in the grain interior and hardening in stage I was affected by the Cu concentration. In stage Ⅱ, decomposition of the αsolid solution to a PdCu ordered phase(L1o type) and an Ag-rich α₂ phase occurred and a discontinuous precipitation occurred at the grain boundary. From the electron microscope study, it was concluded that the cause of age-hardening in this alloy is the precipitation of the PdCu ordered phase, which has AuCu Ⅰ type face-centered tetragonal structure. Precipitation procedure was α→α+α₂+PdCu→α₁+α₂+PdCu at Pd/Cu =1. Ag-Pd-Cu alloy is more effective dental alloy as ageing treatment and is suitable to isothermal ageing at 450℃.

The chief object of this paper is to study prevention and education of the visual impairement through eye disease, its educational implication, educational approach to visual tests and observations on visual behaviors. The results obtained are summarized as follows: 1. Teachers and parents are required to carefully observe their children's visual aspects on the evaluational criteria such as behaviors, gestures and complaints, etc. 2. The most important thing for the judgement of the visual acuity, etiology and associated handcaps is to do early diagnosis with standardized appliances for visual tests. 3. Systematic legal action should be taken for the visual impairment, which will regulate it obligatory for the children to take visual tests. 4. The tests on visual acuity and visual function should be taken simultaneously, and they should include distance vision and near one for effective medical and educational treatment. 5. The cause of the visual impairment in general should be eliminated through improvement of studying environment, with extreme care against the refractive handicaps such as nearsightedness, farsightedness and astigmatism, etc. 6. Appropriate educational measures to judge and counter visual impairment should be established together with medical ones. 7. Visual Efficiency and visual function should be maintained and further developed through visual function training.

이산 vortex에 의하여 simulate된 vortex shedding과 유동 가속으로 인하여 원주에 작용되는 양력과 항력 계산식

이동기 울산대학교 1992 공학연구논문집 Vol.23 No.2

원주에서의 vortex 유출에 대한 이산화 vortex 해석을 할 때 사용할 수 있도록 원주에 작용되는 양력과 항력 계산식을 유도하였다. 이 식들은 유출된 vortex에 관련된 인수들로 나타내졌으며 확장된 Blasius 정리를 조작하여 구하여졌다. 원주 중심에 vortex가 있다고 보는가 없다고 보는가의 두가지 가능한 Image system을 동시에 다루었다. 어느 경우건 현재까지 주목되지 않은 초생 vortex성장율을 포함하는 새로운 향이 이 계산색에 나타남을 보였다. Formulas to calculate drag and lift exerted to a circular cylinder are derived for use in connection with the discrete vortex analysis of vortex shedding from the cylinder. The formulas are expressed in terms of the parameters concerned with the vortices and are obtained by manipulating the extended Blasius theorem. Two possibilities of the image system for a vortex outside the cylinder are covered simultaneously, the difference between these being whether the image system possesses a vortex at the center of the cylinder or not. In either case, the formulas are shown to have a new term containing the growth rates of the so-called nasecnt vortices which has not been noticed so far.

다중 사본 데이타베이스의 신뢰성 있는 연쇄 갱신 프로토콜

夫起東 慶一大學校 1990 論文集 Vol.6 No.1

This paper presents a reliable protocol that quarantees the transmission of a cascading update message to its destination despite failures in one or more sites in a system of multiple copy databases. This protocol is distinquished by not using extra logging devices or checkpoint facilities that are common to many protocols of its type. Instead, it maintains an appropriate number of copies of the message in sites where the message passes. In the case of a failure, the cascading update protocol locates a copy of the message closest to the destination, and resumes transmission of the message from this location.

金東彦,嚴基善,林漢鍾 고려대학교 의과대학 1985 고려대 의대 잡지 Vol.22 No.1

A study on the indirect fluorescent antibody test(IFAT) using the sectioned egg antigen in the liver of white rats was performed. The antigen used was prepared in 6~8㎛ thickness by frozen section at -20℃ of nonembryonated C. hepatica eggs deposited in the liver tissue after 6 weeks of infection. Fluorescein isothiocyanate (FITC) conjugated anti-rat IgG (Goat) was diluted by 64 fold in phosphate buffered saline (PBS, pH 7.2) and counterstaining with a 1/10,000 solution of Evans blue was effected while the fluorescent conjugate is acting by diluting the labelled antiglobulin in the Evans blue solution instead of in the PBS. A total of 22 white rats (B.W. 150g) was divided into 2 groups (A, B) and 200 and 2,000 embryonated eggs were infected orally. All rats were bled by retro-orbital puncture prior to infection and weeks of 1, 3, 5, 7, 9 and 13 after infection. As negative control sera, 60 normal rats were used. Eggs for infection were cultured at room temparature for 4~5 weeks in 0.5% formalin. IFAT was processed by the modified method of Wilson et al. (1974). The results obtained were summarized as follows; 1. The localization of antigens in frozen section of non-embryonated eggs of C. hepatica detected by IFAT was seen on the inner membrane of egg shell. 2. IgG titers detected by IFAT rapidly increased in 3 weeks after infection, thereafter the titers were kept until 5 weeks and gradually decreased in 7 weeks to 9 weeks, then converted into normal by 13 weeks. 3. IgG titers distributed from 16 to 1,024 and showed highest titers in 3 and 5 weeks. 4. Mean titers of 3, 5, 7, 9 weeks after infection were higher in group B than in group A.
