In January 1983, the writer visited a few universites in Japan to survey the recent trend of studies in cultural and social Sciences. At that time what I researched is as follows; In Japan, many a learned society has been organized and the research activities were very lively. Mass publication of scientific periodicals and prompt translation of foreign writings showed the maturity of scientific atmosphere. It true that their study of literature has been performed on the basis of positivism since 1930'. But now Structuralism which consider's literary works as one organic unity of parts became the main basis of literary studies. And, Learned Society of Educational Law has been organized in Japan. In consequence, the level of researches in educational law could be remarkably high. So, it is necessary for us to study the law of education. For, to make it better, we must know not only the universal principles of education but also specific ones derived from the peculiar characteristics of Korean education. At the same time, in Japan, Department of the Law of Industrial Administration was established in 14 universities including Japan University. And with the help of it, companies could improve the efficiency in dealing with judicial affairs related with industrial administration. So, to be a winner in the international trade competition, it is also required for us to study the judicial affairs of industrial administration.

35Ghz-마이크로스트립 패치 어래이 안테나의 설계

李文秀 慶尙大學校生産技術硏究所 1995 生産技術硏究所論文集 Vol.11 No.-

E면과 H면에서 빔폭 4×4°, SLL-20dB인 35GHz 마이크로스트립 패치 안테나를 설계하였다. 어레이의 전류분포는 Dolph Tchebyshev분포와 Tapered Taylor 분포를 사용하였다. 어레이의 기본 방사소자는 입력임피던스를 줄이기 위해서 인셋(Inset)을 둔 구형 마이크로스트립 소자를 택하였다. 어레이의 크기는 16×16이고 소자간의 간격은 주어진 안테나 크기를 고려하여 0.8λ로 하였다. 횡형 빔을 얻기 위해 각 소자를 동위상으로 급전하는 병렬 급전방식을 사용하였다. 실험결과 SLL이 다소 높게 나타나는 것은 에칭의 오차, 표면파의 영향, 임피던스 부정합, 소자간의 상호결합 등이 원인으로 생각된다.

The Purpose of the Study was to determine whether the glutamate ingestion prior to exercise would reduce the lactat formation and its clearance in exercising mscle tisue during Submaximal and maximal execise. Six elite distance rummers particapated in this study. The Subjects had a half dose of glutamale(15.6mg .Kg?? ??) at 45min and ingested rest dose at prior to exerise. The test Performed twice. One was Performed in the track and the other was in the Lab. Blood Smples were obtained from catheter which was placed in the antecubital vein (Lab test) and finger tip Samples (Feld test) Unaltered blood lactate was observed in both trials, but, tended to less lactate concentration with glutamate ingestion than that of without glutamate ingestion. The recovery rate of blood lactate was markely rapid with glutamate ingestion in the field test. Unchanged in heart rate was founded in both trials. It many Suggest that, the additional supplement st of glutamate can improve execise performance limiting lactate formation or induce its rapid clearance from the muscle fissue.

단형 마이크로스트립 소자의 여파성에 관한 연구

이문수 제주대학교 1984 논문집 Vol.17 No.-

The fdtering properties of microstrip planar networks are explained by introducing the two types of transmission zeros, modal and interaction zeros. A rectangular microstrip element can be represented by its approximate equivalent circuit, from which we are able to realize Cauer-Chebyscheff low-pass filters. Experiment results show a good agreement with the characteristics of the prototype fiiter in the pass-band, but are poor in the stopband due to the higher order modes contniutions which are neglected in deriving the equivalent circuit.

폴리에스테르纖維의 알칼리加工에 있어서 界面活性劑의 影響

李廷玟,李文洙 충남대학교 공업교육연구소 1982 論文集 Vol.5 No.1

This study has been investigated on the effects of weight loss, breaking strength, Hunter whiteness, handle, dry soiling and static charge when polyester fabric was treated with sodium hydroxide solution by conjunct treatment with cationic surfactant such as quaternary ammonium salt. The effect of alkali treatment was increased to more than ten times by conjunct treatment with cationic surfactant. The effective cationic surfactant concentration was between 5g/ℓ and 10g/ℓ in dilute sodium hydroxide solution. According to the increases of concentration of sodium hydroxide and surfactant, breaking strength was decreased and handle was improved. The whiteness of polyester fabric was decreased by conjunct treatment with cationic surfactant. Hydrophilic property of polyester fabric was not increased by alkali treatment. It was found that anti-static finish must be carry out on alkali treatment.

Lateral epicondylitis is characterized by pain at the lateral aspect of the elbow, commonly associated with resisted wrist or finger extension and gripping activities. Lateral epicondylitis is also known such as lateral epicondylosis, tennis elbow, or tendonitis of the wrist extensor muscles, especially extensor carpi radialis brevis. Lateral epicondylitis is a common musculoskeletal lesion in the clinical states, so physical therapist usually meet a patients who has the lateral epicondylitis. But many of physical therapists are treating patients based on a self know-how, so I want to describe a systematically about lateral epicondylitis and give a objective information on the lateral epicondylitis. And now I want that they will be treat patients with lateral epicondylitis not a self-experience but based on a objective information.

The present study examined the characteristics of behavior induced by dopamine agonists following treatment with 6-hydroxydopamine(6-OHDA) unilaterally into left striatum in rats. 6-OHDA was administered at doses of 8.16 and 24 ㎍/2㎕(in 0.1% ascorbic acid) into dopaminergic neurons in left striatum of 7 weeks old rat under anesthetic. Locomotor activity was significantly decreased at 1 week following 6-OHDA-administration in 7 weeks old rats. The contralateral circling behaviour was inducd by apomorphine(5 ㎎/㎏, I.p.) after 1 week following 6-OHDA(24 ㎍/2㎕) treatment, and was further increased by repeated administration of apomorphine at 2, 3 and 4 weeks. The contralateral circling behavior was also induced by lisuride and 1-dopa in a dose dependent manner, but not by SK & F 82526 in 7 weeks old rats treated with 6-OHDA, The contralteral circling behavior ws significantly higher in 21 weeks old rats but significantly lower in 35 weeks old rats when compared with 7 weeks old rats. The contralateral circling behavior induced by apomorphine did not differ significantly in and 35 weeks old male and female rats. These results suggest that 6-OHDA treatment into left striatum causes remarkable destruction of intrastriatal dopaminergic neurons leading to dopaminergic receptor supersensitivity. Thus, the contralateral circling behavior induced by apomorphine may be used as indicator for neurodegenerative diseases.

Zipper CMOS PLA 의 설계 및 테스트

이건기,한석붕,이문수 慶尙大學校生産技術硏究所 1988 生産技術硏究所論文集 Vol.4 No.-

In this paper, a new circuit type, the Zipper CMOS PLA, is described. Then a testable design and testing method for it will be discussed. The Zipper CMOS PLA has the regular structure of PLA and a NAND-NAND logic Zipper CMOS circuit. Therefore it incorporates all the advantages of dynamic CMOS circuit and array logic. In the testable design, feedback loops are formed in Zipper CMOS PLA by adding simple extra circuits. The oscillation, in test mode, occurs through the loops and can be observed at the outputs. By the proposed method, test application and evaluation are easy. The fault coverage is improved. The algorithms are also proposed, which add the extra circuits to the Zipper CMOS PLA and generate the test patterns. The validity of the designs is verified by performing the logic level simulation. Also the proposed algortithms are realized on VAX 11/750(UNIX) in C language.

MMIC 분배증폭기의 잡음지수 해석

李文秀 慶尙大學校生産技術硏究所 1987 生産技術硏究所論文集 Vol.3 No.-

The noise figure of the MMIC distributed amplifier can be analyzed for lossless case when we neglect the losses on the gate and drain transmission lines and for lossy case when we consider the losses on the gate and drain transmission lines of the distributed amplifier. The calculated noise figures in both cases are compared with the experimental results. At higher frequencies the calculated noise figure is quite agreement with the measured one while there is a nice bit of discrepancy between the two noise figures at lower frequencies.

질화 분위기에서 결정화 된 Fe_(73.5)Si_(13.5)B_(9)Cu₁Nb₃ 연자성 합금의 자기적 성질

이기선,박인수,이기안,김문철,장석훈 대한금속재료학회 2003 대한금속·재료학회지 Vol.41 No.11

Amorphous Fe_(73.5)Si_(13.5)B_(9)Cu₁Nb₃ alloy was crystallized in nitriding atmosphere of mixture gas of NH₃ and hydrogen. The crystallization at 823K showed the high electrical resistivity ranging from 494 to 538 mW-cm, which was higher level compared with nano-crystalline Fe_(73.5)Si_(13.5)B_(9)Cu₁Nb₃ alloy with a resistivity of about 110 mW-cm. Through the nitridation treatments, the amorphous alloy was transformed into nano-sized crystalline Fe3Si including iron nitrides such as γ' -Fe₄N phases. EPMA-concentration depth profiles confirmed an existence of nitrogen-rich region on the surface of the alloy ribbon, leading to the preferential formation of g -Fe4N phase. The formation of γ' -Fe₄N phase leaded to an increase of the resistivity and provided stable permeability and a low core loss at high frequency.
