The effects of carbon coating onto graphite filler on the structure and properties of carbon foams
Ji-Hyun Kim, Do Young Kim, Young-Seak Lee 한국탄소학회 Carbon Letters 5 Pages
한국탄소학회 Carbon Letters 2017, Vol.21 16 111-115 (5 pages)
Carbon foams (CFms) are of crucial importance in electrical and mechanical devices due to their high thermal conductivity used for eliminating high heat flow and maintaining low temperatures [1]. The most common CFms are types of aluminum alloys, copper and diamond. However, the mechanical properties of metal-based heat sink materials are difficult to control at temperatures over 550°C [2,3]. Thus, CFms are actively investigated as heat sink materials because of their good properties, such as... -

초저주파 대역 수중 자체소음 저감에 관한 실험 연구
이성욱, 이용국, 김성렬, Lee. Seong-Wook, Lee. Yong-Kuk, Kim. Seong-Ryul 한국음향학회 한국음향학회지= The journal of the acoustical society of Korea 5 Pages
한국음향학회 한국음향학회지= The journal of the acoustical society of Korea 2011, Vol.30 No.1 17-21 (5 pages)
수중에서 음향신호를 측정할 때에 청음기 주위에서의 유동에 의해 발생하는 초저주파 대역 자체소음을 저감시키기 위해 청음기 주위에 다공성 발포재를 씌우는 기법의 효과를 해상 실험을 통해 고찰하였다. 두께가 다른 10 ppi 폴리우레탄 발포재를 이용하여 실험한 결과, 2-10 Hz 대역에서 발포재의 두께가 1 cm일 때에는 최대 20 dB 그리고 발포재의 두께가 3 cm인 경우에는 최대 28 dB의 자체소음 저감 효과가 있음을 확인하였다. -
Influence of bronchoalveolar lavage on thoracic radiography in the horse
Ann K. Barton, Thorben Schulze, Marcus G. Doherr, Heidrun Gehlen 대한수의학회 Journal of Veterinary Science 7 Pages
대한수의학회 Journal of Veterinary Science 2018, 제 19권 제 4호 13 563-569 (7 pages)
Bronchoalveolar lavage (BAL) and thoracic radiography are routinely performed diagnostic procedures. We hypothesized that BAL increases the interstitial opacity of caudoventral and caudodorsal thoracic radiographs. Fifty-three horses, including 8 clinic owned and 45 from a referral hospital population, were classified as healthy controls (n = 12), severe equine asthma (recurrent airway obstruction, n = 12) or mild-to-moderate equine asthma (inflammatory airway disease, n = 21) based on the... -
Effects of Vitamin D on Blood Pressure and Endothelial Function
BokyungMin 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 8 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2013, Vol.17 No.5 2 385-392 (8 pages)
Vitamin D deficiency is prevalent, primarily due to limited sun exposure, which may be observed in urban areas, or as a result of modern lifestyles. Common myths about vitamin D persist, including that it is mostly obtained from the diet and is only essential for bone and mineral homeostasis. Nonetheless, advances in biomedical science suggest that vitamin D is a hormone that is integral to numerous physiologic functions in most cells and tissues. Therefore, abnormal vitamin D levels may... -
Screening of Endophytic Antagonistic Bacterium from Phellodendron amurense and Their Biocontrol Effects against Canker Rot
Shujiang Li, Xinmei Fang, Hanlian Zhang, Yanling Zeng, Tianhui Zhu 한국식물병리학회 The Plant Pathology Journal 9 Pages
한국식물병리학회 The Plant Pathology Journal 2019, 35권 3호 5 234-242 (9 pages)
Thirty-four strains of bacteria were isolated from Phellodendron amurense. Using Nectria haematococca as an indicator strain, the best strain, B18, was obtained by the growth rate method. The morphological, physiological and biochemical characteristics of strain B18 and its 16S DNA gene sequence were identified, and the biocontrol effect of strain B18 was assessed in pot and field tests, as well as in a field-control test. Drilling methods were used to determine the antibacterial activity of... -
Disinfection by Ozone Microbubbles Can Cause Morphological Change of Fusarium oxysporum f. sp. melonis Spores

한국식물병리학회 The Plant Pathology Journal 2018, 34권 4호 8 335-340 (6 pages)
To investigate the difference in the disinfectant efficiency of ozone microbubbles (O3MB) and ozone millibubbles (O3MMB), the morphological change of the treated Fusarium oxysporum f. sp. melonis spores was observed with scanning and transmission electron microscopies (SEM and TEM). The disinfectant efficiency of O3MB on F. oxysporum f. sp. melonis spores was greater than that of O3MMB. On observation with SEM, it was revealed that morphological change of F. oxysporum f. sp. melonis spores was... -
Growth Promoting Rhizospheric and Endophytic Bacteria from Curcuma longa L. as Biocontrol Agents against Rhizome Rot and Leaf Blight Diseases

한국식물병리학회 The Plant Pathology Journal 2018, 34권 3호 8 218-235 (18 pages)
Plant growth promoting rhizobacteria and endophytic bacteria were isolated from different varieties of turmeric (Curcuma longa L.) from South India. Totally 50 strains representing, 30 PGPR and 20 endophytic bacteria were identified based on biochemical assays and 16S rDNA sequence analysis. The isolates were screened for antagonistic activity against Pythium aphanidermatum (Edson) Fitzp., and Rhizoctonia solani Kuhn., causing rhizome rot and leaf blight diseases in turmeric, by dual culture and... -
Flexural, electrical, thermal and electromagnetic interference shielding properties of xGnP and carbon nanotube filled epoxy hybrid nanocomposites
Young Sil Lee, Yeon Ho Park, Kwan Han Yoon 한국탄소학회 Carbon Letters 6 Pages
한국탄소학회 Carbon Letters 2017, Vol.24 6 41-46 (6 pages)
The microstructure, flexural properties, electrical conductivity, thermal conductivity and electromagnetic interference (EMI) shielding effectiveness (SE) of epoxy composites filled with multi-walled carbon nanotubes (CNTs), exfoliated graphite nanoplatelets (xGnPs) and CNT-xGnP hybrid filler were investigated. The EMI SE of the CNT-xGnP hybrid composite was higher than 25 dB at 100 MHz while that of the xGnP based composite was almost zero. The flexural modulus of the CNT-xGnP based epoxy...
