An Analysis on Direct-Contact Condensation in Horizontal Cocurrent Stratified How of Steam and Cold Water
Lee. Sukho, Kim. Hho-Jung 한국원자력학회 Journal of the Korean Nuclear Society 11 Pages
한국원자력학회 Journal of the Korean Nuclear Society 1992, Vol.24 No.2 130-140 (11 pages)
동방향 성층이상유동에서의 직접적촉 응축현상을 일차원 모델인 RELAP5/MOD2와 /MOD3를 이용하여 해석하였으며, 해석결과를 Northwestern의 실험결과와 비교·검토하였다. 해석결과 RELAP5의 공유열전달 모델은 동방향 성층이상유동에서 응축율을 비교적 잘 예측하고 있다. 그러나 공유접촉면에 파형이 생기는 경우는 물경계두께 및 국부 열전달계수는 유사한 범위로 일치할분 현상을 예측하는데 상당한 차이가 있다. -
Rapamycin treatment during in vitro maturation of oocytes improves embryonic development after parthenogenesis and somatic cell nuclear transfer in pigs
Joohyeong Lee, Jong-Im Park, Jung Im Yun, Yongjin Lee, Hwanyul Yong, Seung Tae Lee, Choon-Keun Park, Sang-Hwan Hyun, Geun-Shik L 대한수의학회 Journal of Veterinary Science 8 Pages
대한수의학회 Journal of Veterinary Science 2015, 제 16권 제 3호 16 373-380 (8 pages)
This study was conducted to investigate the effects of rapamycin treatment during in vitro maturation (IVM) on oocyte maturation and embryonic development after parthenogenetic activation (PA) and somatic cell nuclear transfer (SCNT) in pigs. Morphologically good (MGCOCs) and poor oocytes (MPCOCs) were untreated or treated with 1 nM rapamycin during 0–22 h, 22–42 h, or 0–42 h of IVM. Rapamycin had no significant effects on nuclear maturation and blastocyst formation... -
A study on chondrogenic potential in mandibular and limb bud mesenchymal cells of human embryos : A possible role of protein kinase C
Yoon-Ah Kook, Eun-Cheol Kim, Sang-Cheol Kim 대한치과교정학회 The Korean Journal of Orthodontics 10 Pages
대한치과교정학회 The Korean Journal of Orthodontics 1996, 제 26권 제 6호 3 667-676 (10 pages)
We have examined the in vitro stage-related chondrogenic potential of human mandibular and limb bud mesenchyme cells using micromass culture, Our results indicate that limb bud mesenchyme cells as early as stage 16 by Carnegie system (37 days), well before the initiation of in vivo chondrogenesis, have chondrogenic potential which is expressed in micromass culture, These results are correlated with stage-related chondrogenic potential of human limb bud in vivo as a result of Alcian blue... -
Ethyl linoleate inhibits α-MSH-induced melanogenesis through Akt/GSK3β/β-catenin signal pathway
Gyeong-AKoSomiKimCho 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 9 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2018, Vol.22 No.1 6 53-61 (9 pages)
Ethyl linoleate is an unsaturated fatty acid used in many cosmetics for its various attributes, such as antibacterial and anti-inflammatory properties and clinically proven to be an effective anti-acne agent. In this study, we investigated the effect of ethyl linoleate on the melanogenesis and the mechanism underlying its action on melanogenesis in B16F10 murine melanoma cells. Our results revealed that ethyl linoleate significantly inhibited melanin content and intracellular tyrosinase activity... -
Biogenic Volatile Compounds for Plant Disease Diagnosis and Health Improvement
Rouhallah Sharifi, Choong-Min Ryu 한국식물병리학회 The Plant Pathology Journal 11 Pages
한국식물병리학회 The Plant Pathology Journal 2018, 34권 6호 1 459-469 (11 pages)
Plants and microorganisms (microbes) use information from chemicals such as volatile compounds to understand their environments. Proficiency in sensing and responding to these infochemicals increases an organism’s ecological competence and ability to survive in competitive environments, particularly with regard to plant-pathogen interactions. Plants and microbes acquired the ability to sense and respond to biogenic volatiles during their evolutionary history. However, these signals can only be... -
Research Notes : Estrogenic Compounds Compatible with a Conditional Gene Expression System for the Phytopathogenic Fungus Fusarium graminearum
한국식물병리학회 The Plant Pathology Journal 5 Pages
한국식물병리학회 The Plant Pathology Journal 2011, 27권 4호 7 349-353 (5 pages)
The ascomycete fungus Fusarium graminearum is an important plant pathogen responsible for Fusarium head blight in small grains and ear rot on maize. This fungus also produces the estrogenic metabolite, zearalenone (ZEA) that causes estrogenic disorders in humans and animals. Previously, we developed a conditional gene expression system for this fungus using a ZEA-inducible promoter (Pzear). In the present study, four other estrogenic compounds, including β-estradiol, estriol, estrone, and... -
Synthesis and characterization of carbon doped TiO₂ photocatalysts supported on stainless steel mesh by sol-gel method
JO. Tijani, OO. Fatoba, TC. Totito, WD. Roos, LF. Petrik 한국탄소학회 Carbon Letters 12 Pages
한국탄소학회 Carbon Letters 2017, Vol.22 6 48-59 (12 pages)
This study synthesized pure anatase carbon doped TiO₂ photocatalysts supported on a stainless steel mesh using a sol-gel solution of 8% polyacrylonitrile (PAN)/dimethylformamide (DMF)/TiCl₄. The influence of the pyrolysis temperature and holding time on the morphological characteristics, particle sizes and surface area of the prepared catalyst was investigated. The prepared catalysts were characterized by several analytical methods: high resolution scanning electron microscopy (HRSEM), energy... -
Adsorption capability of activated carbon synthesized from coconut shell
Md Shariful Islam, Bee Chin Ang, Samira Gharehkhani, Amalina Binti, Muhammad Afifi 한국탄소학회 Carbon Letters 9 Pages
한국탄소학회 Carbon Letters 2016, Vol.20 1 1-9 (9 pages)
Activated carbon was synthesized from coconut shells. The Brunauer, Emmett and Teller surface area of the synthesized activated carbon was found to be 1640 m2/g with a pore volume of 1.032 cm3/g. The average pore diameter of the activated carbon was found to be 2.52 nm. By applying the size-strain plot method to the X-ray diffraction data, the crystallite size and the crystal strain was determined to be 42.46 nm and 0.000489897, respectively, which indicate a perfect crystallite structure. The... -

본 연구에서는 포화수증기와 공기의 혼합기내에서 분무수적으로의 열 및 질량 전달률을 계산하기 위하여 수적의 부분혼합모형과 비혼합모형에 대하여 수적내 과도온 도분포의 해석해를 적용성이 보장되면서도 계산상의 어려움이 수반되지 않는 형태로 구하기 위하여 수적내부의 열전도해석에 있어서 적분법을 적용하였다. 적분법으로 얻어지는 과도온도분포의 해는 유한차의 다항식으로 표시되어 비혼합모형인 경우 각시 간 구간의 경계에서의 온도분포가 연속성을 유지하면서 물성치들의 온도에 대한 종속 성이 쉽게 고려되고 계산도...
