Theoretical Photoionization Spectra for the Mg-like S4+ Ion in the Energy Range Between the S5+ 4s and 4f Thresholds

김대성,권덕희 한국물리학회 2014 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.64 No.5

The partial and the total photoionization cross sections of the Mg-like S4+ ion, leaving the residualS5+ 3l and 4l states from the ground 3s2 1Se and the excited 3s3p 3,1Po initial states, have beencalculated for photon energies ranging from the S5+ 4s to the S5+ 4f threshold. The complexfeatures appearing in the cross sections represent the tangled autoionizing Rydberg resonancesconverging to the different S5+ 4l thresholds. The present results are compared with the availableprevious National Institute of Standards and Technology(NIST) and Opacity Project(OP) results.

Resonant Structures of Overlapping Autoionization Rydberg Series in Photoionization of the N3+ Ion

김대성,김영순 한국물리학회 2007 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.51 No.I

The resonant structures of absolute photoionization cross sections for N$^{3+}$ ion are calculated and compared with the recent experimental measurements and the previous calculations performed in the Opacity Project. We have used a noniterative eigenchannel R-matrix method, which is different from the R-matrix used in the Opacity Project. Comparisons with experimental results for the photoionization of the $^1S^e$ ground state and the $^{1,3}P^o$ excited states of N$^{3+}$ in the photon energy range 62 -- 90 eV show overall good agreement with the present theoretical results. The lower members of the autoionizing Rydberg series converging to each of the N$^{4+}$ $2p$ threshold are identified and discussed The resonant structures of absolute photoionization cross sections for N$^{3+}$ ion are calculated and compared with the recent experimental measurements and the previous calculations performed in the Opacity Project.

A 45-Year-Old Man With Recurrent Dyspnea and Hemoptysis during Exercise: Exercise- Induced Pulmonary Hemorrhage/Edema

김대성,이민혁,권오정,정인범,손지웅,나문준,권선중 대한결핵및호흡기학회 2015 Tuberculosis and Respiratory Diseases Vol.78 No.4

A 45-year-old man presented with dyspnea and hemoptysis during exercise. A chest computed tomography (CT) revealed multifocal diffuse patchy ground glass opacity and interlobular septal thickening in both the lungs. Permeability pulmonary edema or pulmonary hemorrhage was suspected. Serologic studies for autoimmune disorders and vasculitis were negative. There was no laboratory evidence of coagulopathy, other hematopoietic disease or infectious disease. Considering correlation with exercise, we diagnosed exercise-induced pulmonary hemorrhage (EIPH) or exerciseinduced pulmonary edema (EIPE). The patient was managed with antifibrinolytics, antibiotics, and antitussive agent. After a week, follow-up chest CT revealed completely resolved pulmonary hemorrhage. About 2 months after the first event, he visited again with dyspnea and hemoptysis during running. In the present study, we report a case of recurrent pulmonary hemorrhage after exercise.

萬葉假名와 한국 한자음 - 微韻의 반영음 /웨/ -

김대성 한국일어일문학회 2012 日語日文學硏究 Vol.82 No.1

The aim of this study is to propose a new theory “the first era of the period of Wei-Jin North and South Dynasties” against Ancient Chinese Theory and especially Post-Modern Chinese Theory on the fact that Sino-Korean rendered some characters of Wei Rhyme(微韻) of Zhi Rhyme Group(止攝) by /wəi/(웨), not /wi/(위). To sum up, the following grounds can be considered: (1) Because /wəi/ is written in Jungseonghye of Hunminjeongeum Haerye but /wjəi/is not, it is clear that phonological system in Middle Korean lacks the latter. But if /wəi/ represents Post-Modern Chinese, Middle Korean might accept the latter because of its tending to write the nearest original sound like /cujəi/( 嘴) in Junggan Nogeoldae Eonhae.; (2) As Cheobhaesineo, the Japanese study material in Modern Korean has not /e/ but /jə/ ore /jəi/ for Japanese /e/-column orthography,there is a stronger possibility of /wjəi/ than /wəi/ in case of Post-Modern Chinese Theory.;(3) On the grounds of Mandarin /uei/ in Contemporary Chinese being pronounced as [uei] in high-and-level and rising tones, we assume that the vowel of Wei rhyme in the first era of the period of North and South Dynasties might be [e], and it was rendered as /ə/ and became /wəi/.; (4) One of the grounds is the fact that Manyōganas 氣希旣were borrowed for /kë/ or the other /e/-column in Pre-Ancient Chinese instead of being loaned for /kï/ or the other /i/-column in Ancient Chinese.; (5) We suppose the vowel of Zhi(脂) rhyme might be [e] and one of Wei(微) rhyme [e] based on the two reasons,one of which is that Wei rhyme rhymed with Zhi rhyme in the first era of the period of North and South Dynasties by Wangli’s study, and the other is that Zhi rhyme with the other /i/-column in Ancient Chinese was used for /e/-column such as /ke/・/ne/(祁尼)in Pre-Ancient Chinese.

For this data quality analysis case, S finance domain users were questioned and analyzed on the data quality issues. Also, an approach of the information quality improvement based on the 6 sigma was suggested. It suggests ⑴ data quality management process based on the DMAIC, ⑵ factors for data quality management and ⑶ an organization view for managing data quality.

止攝 之韻의 중고음에 대하여

김대성 한국일본문화학회 2012 日本文化學報 Vol.0 No.55

The aim of this study is to verify the validity of my reconstruction Zhi rhyme(之韻) [ i i] and [i i] in Zhi rhyme group(止攝), using the literature on Sino-Korean, Many? Kana or Japanese phonetic alphabet, Sino-Vietnamese and Sino-Tibetan. To sum up, the following grounds can be considered : (1) In fourth division all the initials in Zhi rhyme except apical sibilants that have something to do with Pre-Ancient Chinese are /이/ in Sino-Korean, whereas in third division especially velars and laryngeals are /의/. The fact that Sino-Korean has vowel /으/ of final /의/ in velars and laryngeals implies it had central vowel in Ancient Chinese. ; (2) In third division except velars that have the other /i/ or /i/ in Many? Kana, all the other initials are /i/ in Zhi rhyme, and in fourth division all the initials are /i/. However, in Pre-Ancient Chinese Many? Kanas as 思里已 are /so/·/ro/·/yo/, that is, the other /o/ or /o/, which means that vowels in Zhi rhyme are strong and central [ ]. In Ancient Chinese the weakening of [ ] in [ i i] and [i i] may be suitable for /i/. ; (3) In Sino-Vietnamese and Sino-Tibetan the third and fourth divisions are rendered as /i/ in all the initials except dentals’s [ ] in Sino-Vietnamese. The fact tells us two assumptions: vowel might be weak and ending [i]. In Sino-Vietnamese we can trace the vowel [ ] in Zhi rhyme that may be rendered in Pre-Ancient Chinese.
