내시경적 역행성 담췌관조영술 후 발생한 급성췌장염의 발생인자로 여러 가지 인자들이 관여하지만 특히 담췌관조영술 시행 후 과도한 췌선방 조영화에 의한 중증의 췌장염 증례를 경험하였기에 보고하는 바이다 Endoscopic retrograde cholangiopancreatography (ERCP) has been considered as a valuable tool for the diagnosis and management of disease of the pancreas and biliary tree. Post-ERCP pancreatitis is the most frequent and clinically significant complication following ERCP. But a few complication associated with this procedure are unforeseeable. Specially, acinarization as a result of a careless cooperation between operator and assistant may be influenced in complications of ERCP. Severe post-ERCP pancreatitis is rare complication, and its prognosis will be poor. Therefore, careful process and good relationship between operator and assistant in ERCP may be prevented this complication, but is not clear. Neglect of acinarization may be resulted in more aggravation of pancreatitis. We have cared for one patient with severe post-ERCP pancreatitis with pseudocyst after water-soluble contrast media spreading into the acini (acinarization) via ERCP in resolving phase idiopathic pancreatitis.
CaO·2Al₂O₃와 인산의 반응을 이용한 화학결합 세라믹스에 관한 연구
김세기,송태웅 경남대학교 신소재연구소 1995 論文集 Vol.5 No.-
인산염계 화학결합 세라믹스를 함성하기 위하여 활성화 CA₂ 클린커와 인산용액을 수열조건하에서 반응시켰다. 소량의 인산의 첨가는 CA₂클린커의 수화를 지연시켰으나 인산농도가 증가할수록 반응은 증가하였다. 150℃에서 경화체는 비정질 gel이었으며 열처리에 의해 gel은 약 900℃에서 AlPO₄로 결정화하였다. 300℃에서 수열처리한 경화제는 α-AH는 약 500℃에서 분해되었고 AlPO₄와 HAp는 온도가 증가함에 따라 결정화가 증가하였다. To synthesize phosphate chemically bonded ceramics, activated CAz-based clinker and phosphoric acid solution were reacted under hydrothermal condition. The small addition of phosphoric acid into water retarded the hydration of activated CAz-based clinker, but a more addition of phosphoric acid accelerated the reaction. The hardened bodies were amorphous gel a t 150 C and by heating, the gel crystallized into AlPO₄at 900 C. At 300 C. the hardened bodies were the mixture of a-AH, AlPO₄and hydroxyapatite. BY heating the mixture, a-AH decomposed at about 500 C and then more AlPO₄and hydroxyapatite were crystallized at higher temperature.
전남 무안군 농촌지역에서의 나비개체군 변동에 관한 연구
현태현,최세웅 7개 국립대학교 환경연구 논문집 공동발행 위원회 2003 공업기술연구 Vol.3 No.-
To examine the dynamics of butterfly population in a rural area of Muan-gun, where is characterized by agricultural land mixed with low-hill mountains, we monitored butterflies from 2001 to 2003 based on a transect method. Forty-two butterfly species were recorded and the most dominant species during the surveyed years was pieris rapae. Total numbers of recorded butterflies were different ranging from 29(year 2003) to 39(year 2001). Monthly changes of indices of heterogeneity and evenness showed more or less straight graph, which was a different pattern from that of Mt. Yudal, Mokpo. Some butterfly species were inconsistently observed during the years: 3 species in 2002 were not listed in 2001's record, 12 species in 2001 were not listed in 2002's record.
Sei-Woong Choi 한국동물분류학회 2008 Animal Systematics, Evolution and Diversity Vol.24 No.3
We report a species of Notodontidae, Odontosia patricia Stichel 1918 for the first time from Korea. Two males of O. patricia were collected at the end of May, 2008 from Quercus mongolica forest of Jirisan Mt., a Korea Long-Term Ecological Research site. The notodontid-moth fauna and population changes of three years (2005-2007) from Q. mongolica forest site are provided.
Sei-Woong Choi,Sung-Soo Kim 한국동물분류학회 2018 Animal Systematics, Evolution and Diversity Vol.34 No.2
One species of Euteliidae, Targalla delatrix (Guenée) and two species of Nolidae, Nola miyanoi Sasaki and Nola semiconfusa (Inoue) are reported for the first time in Korea. Targalla delatrix can be distinguished by the dark brownish forewings that show the transverse antemedial line, the costally rounded postmedial line and the bowl shaped marking on the costal part of subtermen and the dark brownish hindwings. Nola miyanoi can be distinguished by the whitish forewings that have the band-shaped central fascia with the blackish undulating antemedial line and the dark brownish undulating postmedial line and the whitish hindwings with a light blackish discal dot. Nola semiconfusa can be distinguished by the light grayish forewings that show deeply indented antemedial line, medially strongly projected and dentate postmedial line, a dark brownish subterminal line and a dark brownish termen, and the whitish hindwings with a light grayish discal dot. Adults and genitalia are illustrated and briefly described with their biological and distributional notes.
New Records of Seven Eupithecia (Lepidoptera: Geometridae) from Korea
Sei-Woong Choi,Sung-Soo Kim 한국동물분류학회 2015 Animal Systematics, Evolution and Diversity Vol.31 No.2
The genus Eupithecia Curtis is the largest taxon in Lepidoptera (more than 1,500 species worldwide) and the adults of the genus are characterized by small in size, cryptically colored grayish and brownish forewing, and indistinct basal, ante- and postmedial transverse lines mostly with a definite discal spot on the forewing. Forty-four species have been reported so far in Korea. Herein, we present the first report on seven species of Eupithecia: Eupithecia rufescens Butler (1878), Eupithecia costiconvexa Inoue (1979), Eupithecia daemionata Dietze (1904), Eupithecia persuastrix Mironov (1990), Eupithecia actaeata Walderdorff (1869), Eupithecia suboxydata Staudinger (1897) and Eupithecia costimacularia Leech (1897). Diagnosis, descriptions and figures of the available species are provided.
Three New Records of Arctiine Moths (Lepidoptera: Erebidae; Arctiinae) from Korea
Sei-Woong Choi,Sung-Soo Kim 한국동물분류학회 2016 Animal Systematics, Evolution and Diversity Vol.32 No.4
Here, we report three new arctiine moths for the first time in Korea, Siccia shikatai Kishida, Nudaria ranruna Matsumura, and Pelosia angusta (Staudinger). Siccia shikatai is distinguished by grayish forewings with a thick and blackish antemedial line, a thin, dark brown and dentate postmedial line and a black <-shaped discal spot and grayish hindwing with a dark brown discal dot. Nudaria ranruna is distinguished by the whitish fore- and hindwings and a large, blackish discal dot and thick medial lines on the forewing. Pelosia angusta is distinguished by dark grayish fore- and hindwings and a thick, dark brown, curved medial line on the forewing.
