Lysimachia foenum-graecum Herba Extract, a Novel Biopesticide, Inhibits ABC Transporter Genes and Mycelial Growth of Magnaporthe oryzae
한국식물병리학회 The Plant Pathology Journal 8 Pages
한국식물병리학회 The Plant Pathology Journal 2016, 32권 1호 2 8-15 (8 pages)
To identify a novel biopesticide controlling rice blast disease caused by Magnaporthe oryzae, 700 plant extracts were evaluated for their inhibitory effects on mycelial growth of M. oryzae. The L. foenum-graecum Herba extract showed the lowest inhibition concentration (IC50) of 39.28 μg/ml, which is lower than the IC50 of blasticidin S (63.06 μg/ml), a conventional fungicide for rice blast disease. When treatments were combined, the IC50 of blasticidin S was dramatically reduced... -
Influence of hot-pressing pressure on the densification of short-carbon-fiber-reinforced, randomly oriented carbon/carbon composite
Thakur Sudesh Kumar Raunija and Sharad Chandra Sharma 한국탄소학회 Carbon Letters 9 Pages
한국탄소학회 Carbon Letters 2015, Vol.16 No.1 4 25-33 (9 pages)
The prime objective of this research was to study the influence of hot-pressing pressure and matrix-to-reinforcement ratio on the densification of short-carbon-fiber-reinforced, randomly oriented carbon/carbon-composite. Secondary objectives included determination of the physical and mechanical properties of the resulting composite. The ‘hybrid carbon-fiberreinforced mesophase-pitch-derived carbon-matrix’ composite was fabricated by hot pressing. During hot pressing, pressure was varied from 5... -

Ginseng gintonin is an exogenous ligand of lysophosphatidic acid (LPA) receptors. Accumulating evidence shows LPA helps in rapid recovery of corneal damage. The aim of this study was to evaluate the therapeutic efficacy of gintonin in a rabbit model of corneal damage. We investigated the signal transduction pathway of gintonin in human corneal epithelium (HCE) cells to elucidate the underlying molecular mechanism. We next evaluated the therapeutic effects of gintonin, using a rabbit model of... -

The protective effects of baicalein, one of the flavonoids in Scutellaria baicalensis Georgi, were evaluated against 6-hydroxydopamine (6-OHDA)-induced neuronal damage in mice and cultured human neuroblastoma cells. Nigrostriatal damage was induced by stereotaxically injecting 6-OHDA into the right striatum. Baicalein was administered intraperitoneally 30 min before and 90 min after lesion induction. Animals received a further daily injection of baicalein for 3 consecutive days. Two weeks after... -
The effect of the spinning conditions on the structure of mesophase pitch-based carbon fibers by Taguchi method
Zhao Jiang, Ting Ouyang, Xiangdong Yao, Youqing Fei 한국탄소학회 Carbon Letters 10 Pages
한국탄소학회 Carbon Letters 2016, Vol.19 11 89-98 (10 pages)
Taguchi’s experimental design was employed in the melt spinning of molten mesophase pitch to produce carbon fibers. The textures of the obtained carbon fibers were radial with varied crack angles, as observed by scanning electron microscopy and polarized optical imaging. The diameter, crack angle, preferred orientation, and tensile modulus of the produced samples were examined to investigate the influence of four spinning variables. The relative importance of the variables has been emphasized... -
Effects of phosphorus content and operating temperature on the electrochemical performance of phosphorus-doped soft carbons
Eun Hee Kim and Yongju Jung 한국탄소학회 Carbon Letters 5 Pages
한국탄소학회 Carbon Letters 2014, Vol.15 No.4 7 277-281 (5 pages)
A series of high capacity soft carbons with different phosphorus contents were successfully prepared by carbonizing petroleum cokes treated with hypophosphorous acid at 900°C. The effect of phosphorus content on the electrochemical performance of the soft carbons was extensively investigated. The P-doped soft carbons exhibited greatly enhanced discharge capacities and outstanding rate capabilities with increasing phosphorus content. In addition, the influence of temperature on the... -
Double-walled carbon nanotubes: synthesis, structural characterization, and application
Yoong Ahm Kim, Kap-Seung Yang, Hiroyuki Muramatsu, Takuya Hayashi, Morinobu Endo, Mauricio Terrones, Mildred S. Dresselhaus 한국탄소학회 Carbon Letters 12 Pages
한국탄소학회 Carbon Letters 2014, Vol.15 No.2 4 77-88 (12 pages)
Double walled carbon nanotubes (DWCNTs) are considered an ideal model for studying the coupling interactions between different concentric shells in multi-walled CNTs. Due to their intrinsic coaxial structures they are mechanically, thermally, and structurally more stable than single walled CNTs. Geometrically, owing to the buffer-like function of the outer tubes in DWCNTs, the inner tubes exhibit exciting transport and optical properties that lend them promise in the fabrication of field-effect... -
An Expected Crisis : A Case Study of Volkswagen Diesel Crisis

This exploratory case study analyzes the Volkswagen diesel crisis from a crisis communication perspective. The Volkswagen diesel case provides a unique opportunity to examine how a Fortune 500 company managed (or mismanaged) an intentional corporate misdeed, and to understand the shortcomings of existing crisis communication theories. In analyzing the case, this study adopted the theoretical frameworks from the two dominant crisis communication theories, namely Image Repair Theory and... -
