Chemical and Biochemical Characterization of Doenjang （Korean Soy Paste） Supplemented with Glasswort （Salicornia herbacea L.） and Rice （Oryza sativa L.）

引用

Journal of Food Science and Engineering 2012年第5期2卷 283-292页

作者： Bo young Jeon Da Hye joo Doo Hyun Park Department of Biological Engineering Seokyeong University Seou1136-704 Korea

Four types of Doenjang were prepared from 100% （w/w） defatted soybean （DFS）, a mixture of 80% （w/w） defatted soybean and 20% （w/w） glasswort （DFS-G）, a mixture of 80% （w/w） defatted soybean and 20% （w/w） rice （DFS-R）, or a mixture of 60% （w/w） defatted soybean, 20% （w/w） glasswort and 20% （w/w） rice （DFS-GR）. Maturity of the DFS-G doenjang was the highest, which was proportional to total amino acid content. Antioxidative compounds and total amino acids were relatively higher in the doenjang with glasswort （DFS-G, DFS-GR） than those in the other preparations （DFS, DFS-R）. Succinic and pyroglutamic acid were relatively higher but levulinic acid was relatively lower in the doenjang with glasswort compared to those in the others. Mn, Fe, Zn, and Al were relatively higher in the doenjang with glasswort compared to those in the others. Volatile organic compounds were differently produced depending on doenjang type and influenced definitely by addition of glasswort and rice. Some bacterial communities responsible for meju fermentation were changed during ripening for doenjang whereas others were conserved.

Annealing time dependent structural, morphological, optical and electrical properties of RF sputtered p-type transparent conducting SnO_2/Al/SnO_2 thin films

引用

Transactions of Nonferrous Metals Society of China 2014年第S1期24卷 129-133页

作者： Keun young PARK Ho Je CHO Tae Kwon SONG Hang joo KO Bon Heun KOO School of Materials Science & Engineering Changwon National University Photovoltaic and Optoelectronic device center Korea Photonics Technology Institute

Transparent p-type conducting SnO2/Al/SnO2 multilayer films were fabricated on quartz substrates by radio frequency(RF) sputtering using SnO2 and Al targets. The deposited films were annealed at a fix temperature of 500 °C for different time durations(1-8 h). The effect of annealing time on the structural, morphological, optical and electrical performances of SnO2/Al/SnO2 multilayer films was studied. X-ray diffraction(XRD) results show that all the p-type conducting films possess polycrystalline SnO2 with tetragonal rutile structure. Hall-effect results indicate that 500 °C for 1 h is the optimum annealing condition for p-type SnO2/Al/SnO2 multilayer films, resulting in a hole concentration of 1.14×1018 cm-3 and a low resistivity of 1.38 ?·cm, respectively. The optical transmittance of the p-type SnO2/Al/SnO2 multilayer films is above 80% within annealing time range of 1-8 h, showing maximum for the films annealed for 1 h.

Hepatolithiasis and intrahepatic cholangiocarcinoma: A review

引用

World Journal of Gastroenterology 2015年第48期21卷 13418-13431页

作者： Hyo Jung Kim Jae Seon Kim Moon Kyung joo Beom Jae Lee Ji Hoon Kim Jong Eun Yeon Jong-Jae Park Kwan Soo Byun young-Tae Bak Department of Internal Medicine Korea University college of MedicineGuro Hospital

Although the incidence of hepatolithiasis is decreasing as the pattern of gallstone disease changes in Asia, the prevalence of hepatolithiasis is persistently high, especially in Far Eastern countries. Hepatolithiasis is an established risk factor for cholangiocarcinoma(CCA), and chronic proliferative inflammation may be involved in biliary carcinogenesis and in inducing the upregulation of cell-proliferating factors. With the use of advanced imaging modalities, there has been much improvement in the management of hepatolithiasis and the diagnosis of hepatolithiasis-associated CCA(HLCCA). However, there are many problems in managing the strictures in hepatolithiasis and differentiating them from infiltrating types of CCA. Surgical resection is recommended in cases of single lobe hepatolithiasis with atrophy, uncontrolled stricture, symptom duration of more than 10 years, and long history of biliaryenteric anastomosis. Even after resection, patients should be followed with caution for development of HL-CCA, because HL-CCA is an independent prognostic factor for survival. It is not yet clear whether hepatic resection can reduce the occurrence of subsequent HL-CCA. Furthermore, there are no consistent findings regarding prediction of subsequent HL-CCA in patients with hepatolithiasis. In the management of hepatolithiasis, important factors are the reduction of recurrence of cholangitis and suspicion of unrecognized HL-CCA.
