Some properties of the Projective Fibre Space
Seo, Gyeong-Sig,Choi, Soong-Sig 全北大學校 基礎科學硏究所 1989 基礎科學 Vol.12 No.1
In the classification theory of algebraic varieties and compact complex spaces it is very important to study the pouricanonical map Φ_L:S→P^N of varieties and in order to study Φ_L more closely, we need the concept of the projective fibre space P(F) associated with a coherent sheaf F on an analytic space X. The purpose of this paper is to syudy the relation between the projective fibre space and the inverse image of the coherent sheaf by the given morphism. A complex space is a c-ringed space (|X|, O_X) satisfying the following conditions : a) |X| is hausdorff. b) for every p∈X, there is an open neighborhood U of p such that (U, O_X|U) is isomorphic to some local model.[2] Y is called a closed complex subspace of X if there is a coherent ideal I⊂O_X such that |Y|= supp(O_X/I) and O_Y = (O_X/I) |Yㆍ([2])

Objective : The purpose of this study is to report the improvement in a patient who had Tourette syndrome treated with Hoeyeoksan based on Shanghanlun provisions. Methods: The symptoms of the patient were checked on days 14, 34, 62, 82, 103, and 119 after administration of Hoeyeoksan. Tourette syndrome was evaluated using Yale Global Tic Severity Scale (YGTSS), and oversleep and constipation were evaluated using visual analog scale (VAS). In addition, new clinical implications for the interpretation of Shanghanlun provision 318 were reviewed. Results: Daily tics occurred ten times a day for 14 days after the initial diagnosis but decreased to eight times a day after 34 days, six times a day after 62 days, five times a day after 82 days, twice a day after 103 days, and once a day after 119 days after administration of Hoeyeoksan. Oversleep and constipation improved together with Tourette syndrome. Conclusions: In this study, we observed that Hoeyeoksan had a therapeutic effect by improving the chief complaint of the patient. Hence, the interpretation of Shanghanlun provision 318 must include a patient's behavioral and sleep patterns as predisposing factors of Tourette syndrome.
『傷寒論』 辨病診斷體系에 근거하여 白虎湯 투여 후 호전된 불면증 증례 1례

Objective: This study aimed to report the improvement of a patient with chronic insomnia who was treated with Baekho-tang based on the Shanghanlun disease pattern identification diagnostic system (DPIDS). Methods: The patient’s symptoms were checked on days 19, 37, and 52 after taking Baekho-tang. Chronic insomnia was evaluated by the degree of insomnia, hours spent asleep, and the number of times the patient woke up during the night, which were all assessed by a visual analog scale (VAS) with the Leeds Sleep Evaluation Questionnaire. In addition, new clinical implications for the interpretation of the 350th Shanghanlun provision were reviewed. Results: After administering Baekho-tang for 52 days, based on the 350th Shanghanlun provision according to the DPIDS, the VAS score decreased from 10 to 1. Conclusions: The patient recovered from chronic insomnia. This case report suggests that the words “滑,” “厥,” and “裏” in the 350th provision of Shanghanlun mean physical and psychological causes of insomnia. In addition, Baekho-tang had a therapeutic effect in improving the chief complaint of the patient. Therefore, the interpretation of the 350th Shanghanlun provision requires a new definition that includes the patient's lifestyle, family conflict, and past history of the patient as a cause of chronic insomnia.
진공분무주조법에 의해 제조한 Nimonic 80A 초내열합금 단조재의 기계적 특성

This study investigates the effect of heat treatment on the mechanical properties of a forged Nibased superalloy called Nimonic 80A. Nimonic 80A ingot samples were fabricated by vacuum spray casting to achieve a fine and homogenized microstructure. The ingot samples were subsequently hot-forged with the diameter of 220 mm at 1373 K. From the center to the surface of the forged Nimonic 80A, its average grain size decreased and its micro-Vickers hardness increased slightly. Solution treatment was carried out at 1353 K with 8 hours of air cooling followed by aging treatment, which was carried out in the range of 873- 1073 K with various times from 0.5 to 256 hours. To set the optimum aging conditions, micro-Vickers hardness tests were performed. The maximum hardness value of 388.0 Hv was obtained by aging at 973 K for 32 hours. Also, tensile tests were performed for optimum aging conditions at room temperature and 873 K. The results can be used effectively to perform reasonable heat treatment of Nimonic 80A superalloy.
