  • This study examined the association between genotypes of the isocitrate dehydrogenase 3, beta subunit (IDH3B) gene and economic traits in an $F_2$ population of Duroc and Jeju (South Korea) native black pigs (JBPs). The genotypes was determined the presence/absence of a 304-bp insertion/deletion fragment in the promoter region of the IDH3B gene for JBP, Duroc, and their $F_1$ and $F_2$ progeny. Three genotypes (AA, AB and BB) were found in the $F_1$ and $F_2$ populations, but there was no AA genotype found in JBP and no BB in Duroc. Association analysis results showed the significant differences with carcass weights (CW), backfat thicknesses (BFT) and eye muscle area (EMA) (p<0.05), but not with growth traits including body weights and average daily gains at different stages, reproductive traits including teat numbers, and crude fat contents (CFAT) measured in longissimus dorsi (p>0.05). The $F_2$ pigs possessing the IDH3B BB homozygote had heavier CW ($72.92{\pm}11.133kg$), thicker BFT ($25.75{\pm}6.06mm$), and larger EMA ($23.82{\pm}4.825cm^2$) than those from the other genotypes (p<0.05). These results were estimated that there are biological roles related with IDH3B genotypes resulting development of EMA, BFT, and CW but not with intramuscular fat deposition during late period of pig production. Our findings suggest that the 304-bp insertion allele of porcine IDH3B may be a genetic marker for marker assistant selection for improving meat productivity of the Jeju Black pig and Duroc-related molecular breeding systems.

  • Background : Differential diagnosis of pleural malignant mesothelioma from secondary metastatic adenocarcinoma is often difficult. A variety of pathologic techniques have been developed to make a differential diagnosis of carcinoma from mesothelioma. Immunohistochemistry detecting diverse antigenic substances such as CEA, Leu-M1, Bn-3, S-100 protein, vimentin, CK and EMA has been claimed to be of value as a panel in the differential diagnosis of adenocarcinoma from mesothelioma. The aim of this study was to investigate the suitable antibodies to distinguish mesothelioma from metastatic adenocarcinoma and establish candidate markers in a panel. Methods : Complete, one-hour immunohistochemical staining using antibodies against cytokeratin (CK), epithelial membrane antigen(EMA), S-100 protein, vimentin, B72-3, Leu-M1, and carcino-embryonic antigen(CEA) was applied to cell blocks from 7 mesotheliomas and 7 adenocarcinomas which were confirmed by electron microscopic and histpathologic methods. Results : All adenocarcinomas and 71.4% of mesotheliomas expressed the cytokeratin and EMA. S-100 protein and vimentin were expressed in 57.1% and 42.9% of mesotheliomas and 14.3% and 28.5% of adenocarcinomas, respectively. B72-3 was expressed in all adenocarcinomas, but in none of mesotheliomas. Leu-M1 was positive in 71.4% of the adenocarcinoma and 14.3% of the mesotheliomas. CEA was positive in all adenocarcinomas and 42.9% of mesotheliomas. Leu-M1 and B72-3 were coexpressed in 71.4% of adenocarcinomas but in none of mesothelioma. B72-3 and CEA were coexpressed in all adenocarcinomas, but in none of mesotheliomas. Conclusion : We concluded that B72-3 immunohistochemistry or panel staining of B72-3 and CEA could be recommanded for the differential diagnosis of pleural mesothelioma from metastatic adenocarcinoma.

  • Ultrasound measures of back fat thickness (UBF), eye muscle area (UEMA) and marbling score (UMS) and carcass measures of carcass weight (CW), backfat thickness (BF), eye muscle area (EMA) and marbling score (MS) were available on 26,129 Hanwoo steers. Statistically significant differences by regions of the farms location and birth years-seasons for the steers taken ultrasound measures and their carcass measures (p<0.01) were found. Steers in Gyeonggi province showed the highest values in ultrasound measures and carcass traits except in BF compared to steers in the other provinces. Comparing between ultrasound and carcass measures, UBF was thicker in general than BF in all regions except in Daejeon city. UEMA was higher than EMA in all regions except in Gyeonggior in Jeju provinces. Especially, the difference in Jeonnam province between UEMA and EMA was $7cm^2$ while the differences between UMS and MS ranged from 0.9 to 2.26 depending on the regions of steers located. Steers born in spring showed greater ultrasound or carcass values than those born in autumn. However, carcass measures of steers born in autumn were greater than those born in spring, 2009 except MS. The pearson and residual correlations were 0.63 and 0.65 between UBF and BF, 0.31 and 0.32 between UEMA and EMA and 0.56 and 0.56 between UMS and MS, respectively.

  • Emulsion polymerization was carried out using RMA like MMA, EMA, BMA and Styrene(St.) as monomer for core-shell latex preparation. It was synthesized at $80^{\circ}C$ in the presence of anionic surfactant SLS. FT-IR, TGA and DSC analysis are used to confirm synthesized core-shell emulsion latexes and to investigate the thermal characteristics of them. From analysis of TGA and DSC, the differences of the decomposition rate and the activation energy are not so large. It considers that the pendent group is not affect of the thermal characteristics and stability on core-shell latexes, which is synthesized with RMA and Styrene.

  • Electromagnetometers (EMA) have been widely used in articulatory studies as their temporal resolution can capture most speech activities and the fleshpoint information allows one to readily quantify and analyze tongue shape. However, the drawback is that the data lacks details of activity in the pharyngeal region. Several studies have attempted to estimate the unknown pharyngeal shape of the tongue, but few studies are based on unimodal data containing both front and back regions of the tongue at the same time. We use Stone's ball bearing method to obtain fleshpoint data as well as tongue shape. We further introduce a novel way of connecting balls and attaching them onto the tongue to ensure accurate tracking. An Artificial Neural Network is applied to build a map between observable flesh-points, unknown tongue shape, and pharyngeal region and is optimized to efficiently address nonlinearity.

  • We report a rare case of a patient with meningeal solitary fibrous tumor. A 60-year-old woman presented with right leg monoparesis. Brain magnetic resonance imaging demonstrates a well enhancing huge mass, located in left parietal lobe. Cerebral angiography demonstrating increased vascularity in area of the tumor, which had feeder vessels extending from the internal carotid artery and external carotid artery. A presumptive diagnosis of meningioma or hemangiopericytoma was considered. At surgery, the consistency was firm and had destroyed the dura and skull. A gross total resection was performed. Immunohistochemically, tumor was strongly, and widely, positive for CD34 and vimentin. There was no staining for epithelial membrane antigen(EMA), S-100 protein, cytokeratin, and glial fibrillary acidic protein (GFAP). Differential diagnosis of intracranial solitary fibrous tumor includes fibroblastic meningioma, meningeal hemangiopericytoma, neurofibroma, and schwannoma.

  • A case of chordoid meningioma occurring in a 61-year-old woman who did not have a Castleman's disease is presented. The patient had suffered from headache and motor dysphasia. Laboratory findings are normal. The tumor, located in the left frontal region and associated with peritumoral edema, was totally resected. Surgical specimen revealed a solid mass with irregular surface that measured $3.5{\times}4.5{\times}4cm$. Immunohistochemical staining revealed that the tumor cells expressed epithelial membrane antigen[EMA] focally, but not S-100 protein and glial fibrillary acid protein [GFAP], and the Ki-67 proliferative index of the tumor was 9%. The neoplasm was diagnosed chordoid meningioma of the World Health Organization[WHO] grade II. After total resection, her preoperative headache and dysphasia were disappeared.

  • The objective of this paper is to get excitation forces of the engine at each of the brackets for the prediction of the vehicle interior noise by the powertrain. A powertrain geometry model is produced by CATIA and its FE model is made by MSC/Patran. A vibration mode analysis and a running mode analysis are experimentally implemented. After getting a satisfied MAC value by doing a correlation about a measured mode analysis value and analyzed value through MSC/Nastran software, all components are assembled through MSC/ADAMS software which is a dynamic analysis tool. We can predict the vibration of brackets which is the last points to occur the force of the engine combustion by analyzing the combustion force produced by engine mechanism.

  • Noise radiated from the powertrain is an important factor of the vehicle interior noise. In this paper, Finite Element(FE) model and Boundary Element(BE) models were created. The FE model was updated by doing a correlation between experimental modal analysis(EMA) values and finite element analysis(FEA) values. Main bearing forces were calculated using a running modal data. The forced vibration analysis was simulated using the software MSC/NASTRAN, and the radiated noise was predicted using the software LMS/VIRTUAL.LAB.
