In this study, visual recognition of X-ray images were estimated using hawlet charts. The resolution has achieved excellent result when densities of film were 1.0~1.5. The more thickness of object was increase, the more the resolution was decrease, because scattered X-ray were increased. The more distance of object to film was increase, the more the resolution was decrease, because groedel effect. The more focal spot size was increase, the more resolution was decrease, because unsharpness was increase. The more field size was increase and grid ratio was decrease, the more resolution was decrease, because scattered X-ray were increase. As a result, we could to improve image quality by determination of resolution according to Radiography parameters. And, we proved that hawlet charts were useful for estimate of image quality and set up x-ray radiography.

We have determined the mormal ranges using the probability graph method to the laboratory data. From within ranges there were found that hematolgical normal values and ranges calculated from it were applied to the determination of those, except red blood cells

China, approaching the 21 century, comes to the age of Hu-jintao. These days, the new leaderships in China have lots of domestic and overseas tasks like the senior in the past had. The most important thing among those tasks is to make the national development in 21 century. It aims to make China ultimately powerful and reconstruct the Chinese nation. In order to do such tasks, especially, the prominent imbalance of wealth has to be solved, and they should hush up "the theory of menace in China". By now, it has been seen that the strategies are "harmonious social construction" and "joint development". It is taken notice of whether their aims and strategies are successful or not in the future, and its results will have effects onto Korea as a matter of consequence.
Annealing Polyethylene terephthalate Film의 結晶化度에 관한 硏究 : Polyethlene terephthalate Film
柳德桓 단국대학교 1977 論文集 Vol.11 No.-
Amourphous PET-film being annealing respectively at 80˚C,100˚C,120˚C,140˚C,160˚C,200˚C, and 220˚C in the silicon oil bath, the results measured its crystallinity by the X-ray diffraction method and the density method are as follows. 1) The crystallinity of the resultant PET film gradually increased with the increase of the annealing temperature. 2) The measured-value of crystallinity determined by the X-ray diffraction curves shows to sharpen with the increase of the annealing time and the strongest peak ends at the 30 minutes of the heat-treatment time. 3) With increasing the drawing ratio of PET-film, (11-0) face and (100) face determined by the X-ray diffraction intensity curves along the equator can not practically separat.

프로그래밍 언어에 익숙하지 않은 초보자가 특정 언어의 구문을 쉽게 익힐 수 있도록 도와주는 에디터의 개발은, 날로 증가하는 프로그래머의 수요를 감안할 때 중요한 의의를 갖는다. 본 논문에서는 프로그램의 내부표현인 abstract syntax tree를 중심으로 밀접하게 결합된 도구를 포함하는 구조 중심형 프로그래밍 환경에서 사용 가능한 교육용 에디터의 설계 및 구현에 관하여 논의한다. 구조 중심형 프로그래밍 환경에서 사용자와의 인터페이스를 담당하는 에디터를 설계함에 있어 새로운 도구의 추가로 인한 기능 확장이 용이하도록 고려하였으며, 사용자가 초보자임을 고려하여 에디팅 명령어의 customization이 가능하도록 하였다. 또한 에디터의 구현시 수행상의 효율성을 강조하였다.

Inverter generators are now on the way for further development to eliminate single phase generators and three phase generators. We compared inverter type X-ray apparatus with conventional single phase 2 peak and three phase 12 peak apparatus in the following aspects X-ray output to tube voltage, linearity of X-ray output to mA and exposure time, transmission dose in various thickness of aluminium absorber with different kVp. The output, linearity of inverter type and three phase 12 peak showed increase as compared against of single phase 2 peak X-ray generator. The transmitted doses of inverter type and three phase 12 peak X-ray generators were more increased than single phase 2 peak X-ray generator.
Enzyme 및 Aldali 處理에 依한 Hemp의 精練에 關한 硏究
柳德桓 慶北工業專門大學 1974 論文集 Vol.11 No.-
In order to investigate the retting of bast fibres for hemp stalks, the bacteria named H-1, which was isolated from the various micro-organisms, producing pectinase is applied to retting bast fibres. The results are as follows. 1. In accordance with the time, temperature and pH this bacterial enzyme gives only pectinase activity, but never indicates cellulose hydrolyzing activity. 2. Tensile strengthes of the fibres treated by the enzyme and alkali, were decreased according to increase in time and concentraion. Under decomposition pectin 12.5% the tensile strength is found to be decreased rather than alkali retting. But over the decomposition pectin 12.5% is increased. 3. It is possible to use it as spinning raw materials because it shows better strength than spinning minimum strength value. 4. Whiteness, isolatedness and softness show, in treating sample of enzyme, better than treating sample of alkali.

We have examined the relaxational reponse to the water extract of Angelica gigas Nakai (AG), A. sinensis(Oliv.) Diels (AS), A. acutiloba Kitagawa (AA), and Four-Substance Decoctions (AG-FSD, AS-FSD, AA-FSD) in isolated thoracic aorta from sprague dawley(SD) rat in the presence and absence of endothelium. Rat thoracic aorta was investigated in vessel segments suspended for isometric tension recording by polygraph. Responses to AG, AS, AA and AG-FSD, AS-FSD, AA-FSD were investigated in vessels precontracted with 5-hydroxytryptamine(5-HT) were compared in vasodilation effect. We found that the thoracic aorta segments responded to AG, AS, AA and AG-FSD, AS-FSD, AA-FSD with a dose-dependent vasodilation. The 5-hydroxytryptamine induced contraction at 10-4M were inhibited by 26.3%, 2.7%, 2.1% and 24.6%, 1.1%, 3.2% after addition of the 0.1 g/㎖ water extract of AG, AS, AA and AG-FSD, AS-FSD, AA-FSD. The 5-hydroxytrptamine induced contraction at 10^-4M with and without endothelium were inhibited by 24.6% and 6.9% after addition of the 0.1 g/㎖ water extract of AG-FSD. In conclusion, AG, AS, AA and AG-FSD, AS-FSD, AA-FSD-induced relaxation in the isolated rat thoracic aorta were composed of dose-dependent relaxation. AG-FSD has very potent vasodilation.
