The intradermal test (IDT) has been developed for confirming diagnosis of canine atopic dermatitis (CAD). Prior to performing IDT, rapid immunoassay (Allercept E-screen 2nd generation; ES2G) can detect allergen-specific immunoglobulin E (IgE) antibodies in canine serum. The objective of this study was to evaluate agreement between IDT and immunoassay in diagnosis of CAD in domestic atopic dogs. Forty dogs were diagnosed with CAD in accordance with Favrot’s criteria. Intradermal testing was performed using 39 selected allergens. ES2G detected IgE antibodies specific for three allergen groups, including indoor allergens, grasses and weeds, and trees. Among 19 dogs diagnosed by IDT, the highest positivity was observed in house dust mites, followed by molds, epidermis and inhalants, house dust, and weeds. A total of 28 atopic dogs were evaluated by rapid ES2G immunoassay. Indoor allergens showed the strongest positive reaction, followed by grasses/weeds and trees. IDT and ES2G were performed concurrently in 17 dogs. The results of ES2G showed slight agreement with those of IDT. Level of agreement was highest for indoor allergens, which showed a predictive positive value of 100% in ES2G. These results indicate that a rapid immunoassay may be valuable for predicting the results of IDT in atopic dogs sensitized to indoor allergens.

With the recent hype concerning three-dimensional (3D) printing technology, affordable 3D printers have been launched, enabling individual machine owners to download or create design files and thus produce artifacts. As a design community, Shapeways—which comprises over 300,000 members and 25,000 online shops—commercializes and promotes good ideas using 3D printing technology (Shapeways, 2015). Through Thingiverse, people can globally upload and share design modeling files without cost and print out items as desired. In general, 3D printing communities provide data without charges and witness gradually increasing data sharing rates. Literature on 3D printing mainly focuses on cases of technology-related patents, policies, and intellectual property rights. Thus, there is a paucity of empirical studies on 3D printing users. To overcome the limitations of previous studies, this study first builds on both social cognitive and social capital theories to elucidate the effects of 3D printing community users’ self-efficacy; altruistic tendency; and perceived structural, cognitive, and relational capital on their voluntary knowledge sharing and innovative behaviors. Second, it aims to verify inter-group differences in innovative behaviors of 3D printing community users while considering either high or low levels of fashion innovativeness and fashion involvement. For this verification, antecedents of knowledge sharing are elicited from previous research followed by an interview and a questionnaire survey with 3D printing community users to substantiate such antecedents. Next, the data collected from the interview and survey is analyzed using SPSS 18.0. The results indicate that first, altruistic tendencies influence knowledge sharing, which is consistent with the social cognitive theory, whereas structural, cognitive, and relational capitals affect knowledge sharing, which parallels social capital theory. Second, knowledge sharing in 3D printing virtual communities exerts significant effects on innovative behaviors. This study establishes the antecedents and consequences of knowledge sharing in 3D printing virtual communities and proposes a model for effective knowledge sharing, which is projected to stimulate the application of 3D printing technology in creating and sharing fashion design content and providing substantive data for market formation.

Riptortus pedestris (F.) (Hemiptera: Alydidae) attacks several leguminous crops and its reproductive success is found to be affected by the leguminous host types. Ooencyrtus nezarae Ishii (Hymenoptera: Encyrtidae) is an egg parasitoid of R. pedestris and its quality attributes depend on the host egg quality. We, thus, investigated the performance of O. nezarae on eggs of R. pedestris fed on different leguminous seeds. Eggs collected from R. pedestris female adults obtained from rearing on one of the four hosts such as soybean, adzuki bean, mung bean, and cowpea seeds were exposed as a batch (n=15) to a single 4 to 5 day-old mated female O. nezarae. The eggs exposed were collected after 24 h. Number of parasitized eggs, sex ratio, development times, and adult emergence were recorded. The maximum number of eggs parasitized by O. nezarae were the eggs of mung bean fed R. pedestris. Eggs produced from the adzuki bean fed bugs had the lowest parasitization. There was no difference recorded in the developmental time of parasitoids emerged from the eggs of R. pedestris fed on different legumes. Proportion of male O. nezarae was highest on the eggs of cowpea seed fed adult bugs (26%); the lowest of that was found on the eggs of mung bean fed bugs (22.4%). Ooencyrtus nezarae can successfully parasitize eggs of R. pedestris regardless of hosts food sources. However, eggs of mung bean fed R. pedestris, among the tested legumes, were found to be of the best quality for reproductive success of O. nezarae.

Renal dysplasia is a developmental disorder of the renal parenchyma involving anomalous differentiation. It is characterized by persistent metanephric ducts surrounded by primitive mesenchyme, fetal or immature glomeruli, fetal or immature tubules, interstitial fibrosis, and dysontogenic metaplasia involving tissues such as cartilage. Renal dysplasia has been rarely reported in rats. Here, we observed a small left kidney in a rat used in a short-term repeat toxicity study. The rat showed no clinical signs throughout the study. All parameters, including those reflecting kidney functions, were normal upon hematological examination and urinalysis. Grossly, the kidney was small (5 × 8 mm) and its surface appeared normal. Histological examination revealed that the cortex and medulla were poorly demarcated and contained immature/atrophic glomeruli, immature renal tubules, and mesenchymal cells. The cortex contained immature glomeruli, atrophic glomeruli with cystic dilatation of Bowman’s capsular space, and some atypical tubules. Primitive metanephric tubules in the medulla were larger in diameter than normal collecting ducts, lined by a tall columnar epithelium with pale cytoplasm and basal nucleus, and surrounded by loose mesenchymal cells. Occasional tubules contained pale eosinophilic homogenous material in the lumen. Thus, this was diagnosed as a case of renal dysplasia on the basis of histologic features and is the first reported case of renal dysplasia in Sprague Dawley rats.

Bumblebee, Bombus terrestris is widely used to pollinate various crops, especially tomato, in greenhouses. Mason bee, Osmia cornifrons, which is using as apple pollinator. Here we investigated characteristics on pollinating activity of B. terrestris and O. conifrons at different weather conditions in apple orchard. The foraging activity of O. conifrons was more sensitive than that of B. terrestris at weather conditions including temperature, illumination intensity and wind velocity. The pollinating activity of O. conifrons was very low than that of B. terrestris at a low temperature, cloudy, rainy and windy weather. Therefore, Our results indicated that B. terrestris was suitable for apple pollinator than O. conifrons, especially in low temperature and bad weather.

Virus infections of the honeybee(Apis mellifera) have been increasingly investigated during the last decade. In general, honeybee viruses are widespread and most of them persist as inapparent infections. We screened honeybee colonies for the presence of several bee viruses, including deformed wing virus(DWV), black queen virus(BQCV), Kashmir bee virus(KBV), Israeli acute paralysis virus (IAPV), sacbrood virus(SBV), acute bee paralysis virus(ABPV), using uniplex RT-PCR. Frequently simultaneous infections with different viruses are diagnosed in seemingly healthy bee colonies. Therefore we developed a multiplex RT-PCR assay for the simultaneous detection of multiple bee viruses.

Sacbrood virus (SBV) is one of the most destructive honey bee virus. The virus causes failure to pupate and kills honey bee larvae. The infacted larvae`s color is change to brown. At the end, honey bee colony is destructed. Recently Korean Scabrood virus(KSBV) caused a great loss of Korean honey bee(Apis cerena) colonies for short period. Therefore, We need a highly rapid diagnosis method for rapid detection of KSBV. In this study, We need amicro-scale chip-based real-time PCR system (GeneChecker®). This system was developed for rapid, specific PCR based diagnosis. This system has uncommonly fast heating and cooling system. So We was able to detecting of KSBV in Apis cerena in short time. This system needs small reaction volume(total 10ul). This volume include SsoFast™ Evagreen Supermix and serially diluted cDNA templates showed a high sensitivity of 101copies.That machine can setting each PCR stage time. A specific detection primer set (KSBV-123-F/R) was used to amplify a unique 123bp DNA fragment. This PCR assays using serially diluted cDNA templates showed a high sensitivity of 101 copies. When applied to KSBV-positve samples, the result showed high specifity. The minimum diagnosis time was 9m 47s (30cycle). The amplied positive samples appear red fluorescent color. This novel detection method could be used a PCR-based diagnositic tool (GeneChecker®). The results showed high sensitivity and specifity in short time. And this diagnosis method is expected to be applied to rapidly detect various pathogens.

Sacbrood virus (SBV) is one of the most serious honeybee viruses. The virus causes failure to pupate and death in both larvae and adult bees. Recently, Korean Sacbrood virus (KSBV) caused a great loss in Korean honeybee (Apis cerana) colonies. Although KSBV shows high homology with SBV strains, it has unique motifs and causes different symptoms. Therefore, a simple, sensitive and specific method for detecting KSBV is needed urgently. In this study a reverse transcription loop-mediated isothermal amplification (RT-LAMP) and a novel micro PCR-based detection method, termed ultra-rapid real-time PCR (URRT-PCR) were applied for rapid detection for korean sacbrood virus (KSBV) from honeybees (Apis cerana) infected with SBV in Korea. The LAMP could be detect the virus in RT-LAMP reactions containing 102copies of pBX-KSBV within 30 min, which was 10 times more sensitive than a RT-PCR assay. The URRT-PCR showed high sensitivities which were able to detect 10 copies in the standard assays. In the application of URRT-PCR detection to an KSBV-infected honeybee, the shortest detection time was 10 min 12 sec, including reverse transcription. In addition, these methods could be distinguished between KSBV and other closely-related SBV strains, These rapid methods were rapid molecular-based diagnostic tools and useful tool for the rapid and sensitive diagnosis of KSBV infection of honeybees.

Sacbrood virus (SBV), a causative agent of larval death in honeybees, is one of the most devastating diseases in bee industry throughout the world. Lately the Korean Sacbrood virus (KSBV) induced great losses in Korean honeybee (Apis cerana) colonies. However, there is no culture system available for honeybee viruses, including SBV, therefore, the research on honeybee viruses is practically limited until present. In this study, we investigated the growth and replication of KSBV in cell cultures. The growth of KSBV was demonstrated by RT-PCR, quantitative real-time PCR, TEM and nucleotide sequence analysis. The results demonstrated that SBVshowed the replication signals in mammalian cell lines, including Vero cells without any signs of cytopathic effect (CPE). The results of RT-PCR, quantitative real-time PCR and in vivo infection with KSBV were also indicated the replication. Phylogenetic tree analysis shows our sequence included in distinct group with other SBV strains from China and Korea. It clearly showed the differenciation between field strain and attenuated strain through cell culture. The results of present study demonstrated for the first time that SBV like other animal viruses could be adapted and attenuated in cells through the sequential passages. The sequential adaptation through cell culture could result in discrepancy of pathogenicity of virus and morphological characterization. For this reason, the present results indicated that the cell adapted SBV could be a valuable tool to study the general properties of this emerging virus, including pathogenicity in the future.

The recent development in genetic assisted selection (combining traditional- and genome assisted selection method) and reproduction technologies will allow multiplying elite cow in Hanwoo small farm. This review describes the new context and corresponding needs for genome assisted selection schemes and how reproductive technologies can be incorporated to get more genetic gain for cow genetic improvement in Hanwoo. New improved massive phenotypes and pedigree information are being generated from commercial farm sector and these are allowing to do genetic evaluation using BLUP to get elite cows in Korea. Moreover cattle genome information can now be incorporated into breeding program. In this context, this review will discuss about combining the reproductive techniques (Multiple Ovulation Embryo Transfer; MOET) and genome assisted selection method to get more genetic gain in Hanwoo breeding program. Finally, how these technologies can be used for multiplication of elite cow in small farm was discussed.

Graphene is an attractive material for device applications, but device characteristics are very unstable because the graphene is very sensitive to environmental factors such as charges nearby the graphene, metal contacts, defects, contaminants and other adsorbates. Since the interactions between graphene and environmental factors affect the electrical characteristics of graphene devices, the interpretation of electrical characteristics as simple as current-voltage curves is non-trivial, despite the common practice of using well known electrical characterization methods that have been used in silicon MOSFET. This paper addresses major obstacles in the electrical characterization of graphene devices and offers countermeasures to improve the accuracy of electrical characterization methods.

This paper reports a characteristic motion of a polarity inversion line (PIL) formed at the solar surface, which is newly found by performing a three-dimensional magnetohydrodynamic simulation of flux emergence in the Sun. A magnetic flux tube composed of twisted field lines is assumed to emerge below the surface, forming a bipolar region with a PIL at the surface. A key finding is the successive half-turn rotation of the PIL, leading to the formation of a quadrupolar-like region at the surface and a magnetic configuration in the corona; this configuration is reminiscent of, but essentially different from the so-called inverse-polarity configuration of a filament magnetic field. We discuss a physical mechanism for producing the half-turn rotation of a PIL, which gives new insights into the magnetic structure formed via flux emergence. This presents a reasonable explanation of the configuration of a filament magnetic field suggested by observations.

The gap between the increasing amount of raw sequence data and qualified biological information is widening: it is not possible to provide qualified annotation for new genomes with the same speed at which sequences are generated -- especially with next generation sequencing technologies. Additionally, managing the huge number ofavailable bioinformatics algorithms represents a challenge of its own. Thus, a systemwhich provides maximum annotation quality with approved methods in a minimum of time is absolutely critical as the basis for the R&D pipeline in industrial biotechnology. Also using those various genome annotation, comprehensive knowledge of a fungal’s biosynthetic capacities is the indispensable basis of its usefulness in the biotechnology research. Comparative genomics is on the rise as a potent tool in molecular biology. The publicly available genomes from yeasts and several fungal species are used to comparative genomics method for discovery of functional information in our research. Also we had integrated information from different data sources to dynamically build semantic networks representing up-to-date knowledge, which can then be mined and analyzed. Through those methods, we could inspect the common features and uniques between yeasts and fungal species in the new aspect.

We tested differences in female pheromone production and male response in three species of the genus Adoxophyes in Korea. Females of all three species produced mixtures of Z9-14:OAc and Z11-14:OAc as major components but in quite different ratios. The ratio of Z9-14:OAc and Z11-14:OAc in pheromone gland extracts was estimated to be 100:198 for A. honmai, 100:23 for A. orana, and 100:3880 for A. sp. Field tests showed that males of each species were preferentially attracted to the two-component blends of Z9-14:OAc and Z11-14:OAc mimicking the blends found in pheromone gland extracts of conspecific females. The effects of minor components identified in gland extracts on trap catches varied with species. Addition of 10me-12:OAc or E11-14:OAc to the binary blend of Z9-14:OAc and Z11-14:OAc significantly increased captures of A. honmai males, whereas E11-14:OAc exhibited a strongly antagonistic effect on catches of A. sp. males. Moreover, Z9-14:OH or Z11-14:OH added to the binary blends increased attraction of male A. orana but not A. honmai and A. sp. males, suggesting that these minor components, in addition to the relative ratios of the two major components, play a noteworthy role in reproductive isolation between Adoxophyes species in the southern and midwestern Korea where these species occur sympatrically.
