The oriental fruit fly is a major polyphagous insect pest with a worldwide distribution. We investigated the development time, survivorship, longevity and fecundity of B. dorsalis at six different temperatures. We applied the computer programs – TWOSEX-MSChart and TIMING-MSChart - to analyze our data. We obtained the population parameters – adult preoviposition period (APOP), total preoviposition period (TPOP), oviposition days, eggs per reproductive female, first age of survival rate <50%, proportion of male and female individuals, propoortion of N-type individual, and life table parameters (net reproductive rate, intrinsic rate of increase, finite rate of increase, and mean generation time) - and population projection using two computer programs.

The oriental fruit fly is a major polyphagous insect pest with a worldwide distribution. The effects of temperature on stage-specific development were investigated at eight constant temperatures (13.0, 14.4, 16.2, 19.5, 23.8, 27.7, 31.8 and 34.8℃). Stage-specific lower developmental thresholds and thermal constants were determined using linear regression. The lower and higher temperature threshold (TL and TH) were estimated using the Sharpe-Schoolfield-Ikemoto (SSI) model. The daily adult emergence frequency of B. dorsalis was estimated in relation to adult age and temperature. Thermal performance was compared among B. dorsalis populations from different locations in Taiwan.

The dynastid beetle Allomyrina dichotoma has been used as a herbal medicine. Recently, we performed de novo RNAsequencing of Allomyrina dichotoma and identified several antimicrobial peptide candidates based on in silico analysis.Among them, cationic antimicrobial peptide, Allomyrinasin, was selected and we assessed the anti-inflammatory activitiesof Allomyrinasin against mouse macrophage Raw264.7 cells. The results showed that Allomyrinasin decreased the nitricoxide production of the lipopolysaccharide-induced Raw264.7 cells. In addition, quantitative RT-PCR, ELISA and Westernblot analysis revealed that Allomyrinasin reduced cytokine expression levels in the Raw264.7 cells. Taken together, thesedata indicated that Allomyrinasin had anti-inflammatory activity in the lipopolysaccharide-induced Raw264.7 cells.

Although the grasshopper Oxya chinensis sinuosa has long been used as a food in Korea, there is little data on itsfunctional effects. Thus we prepared and analyzed total RNA from the whole body of adult Escherichia coli non-immunizedand immunized Oxya chinensis sinuosa strains. Using an Illumina Hiseq sequencer, we generated a total of 66,555 pooledtranscriptome and singletons with and without Escherichia coli immunization, respectively. Then, we performed in silicoanalysis of the Oxya chinensis sinuosa transcriptome, using bioinformatics tools for screening putative antimicrobial peptides(AMPs) and 38 AMPs were finally selected and tested their antimicrobial activity of Gram positive, Gram negative bacteriaand antifungal activity with radial diffusion assay. As a result, 5 out of 38 AMPs showed the highest antimicrobial activityand antifungal activity against microbes and it also evidenced with no hemolytic activity.

This study was aimed to evaluate the dose-response the effects of nano-encapsulated conjugated linoleic acids(CLAs) on in vitro ruminal fermentation profiles. A fistulated Holstein cow was used as a donor of rumen fluid. Nano-encapsulated CLAs(LF, 5% of nano-encapsulated CLA-FFA; HF, 10% of nano-encapsulated CLA-FFA; LT, 5% of nano-encapsulated CLA-TG; HT, 10% of nano-encapsulated CLA-TG) were added to the in vitro ruminal fermentation experiment. In the in vitro ruminal incubation test, the total gas production on incubation with nano-encapsulated CLAs was increased significantly according to the incubation time, compared with the control(p<0.05). The tVFA concentrations on addition of LF and HT were significantly higher than that of the control(p<0.05). Thus, nano-encapsulated CLAs might improve the ruminal fermentation characteristics without adverse effects on the incubation process. In addition, the population of Butyrivibrio fibrisolvens which is closely related to ruminal biohydrogenation was increased by adding HT, while decreased by adding LF at 12 h incubation. These results showed that nano-encapsulated CLA-FFA could be applied to enhance CLA levels in ruminants by maintaining the stability of CLA without causing adverse effects on ruminal fermentation profiles considering the optimal dosage.

It is very difficult to get the information about semen quality analysis in transgenic pigs because of limited numbers and research facilities. Therefore, in the present study, we analyzed the semen quality of transgenic boars generated for xenotransplantation research. Briefly, the semen samples were collected from 5 homozygous α1,3-Galactosyltransferase knock-out (GalT-/-) transgenic boars and immediately transported to the laboratory. These semen samples were decupled with DPBS and conducted to analyze semen parameters by a computer-assisted semen analysis (CASA) system. The boar semen were examined all 12 parameters such as total motility (TM), curvilinear velocity (VCL), straight line velocity (VSL), average path velocity (VAP), and hyperactivated (HYP), etc. In results, among the 5 GalT-/- boars, three boars (#134, 144, and 170) showed normal range of semen parameters, but #199 and 171 boars showed abnormal ranges of semen parameters according to standard ranges of semen parameters. Unfortunately, #171 boar showed azoospermia symptom with rare sperm counts in the original semen. Conclusively, assessment of semen parameters by CASA system is useful to pre-screening of reproductively healthy boar prior to natural mating and artificial insemination for multiplication and breeding.

In this study, the glass-forming ability and mechanical properties of newly developed Fe-Mn-Cr-Mo-B-C-P-Si-Al bulk amorphous alloys were investigated, and metalloid elements such as B, C, and P were found to have a strong influence on the properties of the Fe-based amorphous alloys. When the total metalloid content (B, C, and P) is less than 5%, only the crystal phase is formed, but the addition of more than 10% metalloid elements enhances the glass forming ability. In particular, the alloys with 10 % metalloid content exhibit the best combination of very high compressive strength (~2.8 GPa) and superior fracture elongation (~30 %) because they consist of crystal/amorphous composite phases.

We propose to extend the research in responsible luxury by identifying situations where Corporate Social Responsibility(CSR) could actually promote luxury brands evaluation. By using social consensus as one of the determining factor, we argue that when CSR with higher social consensus is communicated through right channel, this information can have positive influence on brand evaluation. This research could contribute to literature on consumer responses to CSR, and to responsible luxury in particular and demonstrate how social consensus and CSR information of luxury brands affects consumers’ evaluations of luxury brands. Our research highlights that responsible luxury brands should carefully evaluate how their CSR communication strategy affects brand evaluations.

The fashion industry is one of the most labor intensive industries, and employs over 25 million workers in over 100 countries (Reinhard, Schmidt, Rützel, & Zentgraf, 2013). There have been many concerns regarding the poor working conditions of garment workers, including their long working hours, forced overtime, and hazardous working environments, especially in developing countries. In Korea, competition has intensified within the industry with the emergence of global fashion companies, which has caused many fashion companies to move their production bases overseas in search of cheaper labor (Son, 2007). Thus, the labor problems that have arisen in the fashion industry are mostly about low wages and the poor working conditions of production workers. However, what about the labor problems of fashion industry workers other than those in production factories? Lee, Kim, Shin, Yoon, Lee, Chang, Chung, and Choi (2009) noted in their study that white-collar workers in fashion companies in Korea work longer hours, receive fewer benefits, and have a higher turnover rate than workers in other industries. In 2015, the poor working environment and low or absent wages of fashion industry interns came under public scrutiny (Kim, 2015; Kwon, 2016). In addition, there were cases in which body size was specified when hiring fashion designers, which raised the question of discrimination based on physical appearance (Kim, 2015). These employment conditions are important factors that influence fashion design majors entering the job market. Hence, regarding this and the physical body size discrimination of fashion designers in the Korean fashion industry, the aims of this paper are twofold: 1) to examine the present situation of physical discrimination by analyzing fashion companies’ job advertisements and 2) to explore fashion major undergraduates’ opinions about job criteria that indicate potential physical discrimination. Two approaches were used in this exploratory study to examine potential hiring discrimination tied to job applicants’ body size; 1) investigation of job advertisements by fashion companies and 2) focus group interviews with fashion majors seniors or graduates looking for a work as fashion designers. First, job advertisements for fashion designers placed on major fashion recruiting sites (e.g., www.saramin.co.kr, www.fashionscout.co.kr, and http://cafe.naver.com/fashionworking) in 2015 were reviewed to determine the current situation of which physical conditions or specific body measurements are set as job requirements or preferred qualifications when hiring fashion designers (n=201). Next, five focus group interviews with seven university seniors each(n=35) were conducted. No fashion companies that were looking for experienced fashion designers only (n=65) included a physical body-size requirement in the job advertisement. Thus 136 fashion designer interns or entry-level fashion designer advertisements were used in further analysis. According to the analysis of the “job requirements”, among those 136 advertisements, 51.5% required education and only 16.2% required a related major along with education, 10.3% required fitting capable size (e.g. female fitting size 55) and 13.2% even presented detailed body measurements (e.g. height 175–178 cm). Among the “preferred” qualifications mentioned in the advertisements, fitting capable size accounted for 6.6%, detailed body measurements accounted for 2%. Analysis results showed that physical conditions capable of fitting were presented more frequently than major as requirements or preferred qualifications, indicating that physical conditions capable of fitting was one of the most important factors for hiring fashion designers. Based on the five focus group interviews, participants’ opinion toward body size requirements in job advertisements were summarized into five themes: 1) Discontent over the unreasonable standard— “Why do I have to have a model figure to become a fashion designer?”; 2) Adapting to given circumstances— “I will lose weight to become a fashion designer”; 3) Frustration over reality that can’t be changed with effort— “I can lose weight, but I can’t get any taller”; and 4) Setting practical alternatives—“I can be a children’s clothing designer instead of women’s”. Most respondents shared a sense of discontent over such hiring requirements and unreasonable discrimination on the grounds of appearance, but they also showed reluctant acceptance of the unreasonable discrimination practiced by employers in the fierce job market. The physical restrictions set as requirements by fashion companies fundamentally deny opportunities to some applicants. Importantly, the outright specification of a physical condition that cannot be overcome through personal effort or improved by the cultivation of skills as a hiring requirement is an infringement upon personal rights. The fashion industry should make efforts to improve its awareness of fashion designers as specialists equipped with design competencies instead of treating them as fitting models simply to save costs.

To overcome the hyperacute immune rejection during pig-to-non-human primates xenotranasplantation, we have produced and bred α-1,3-galactosyltransferase knock-out (GalT —/—) pigs. In this study, the somatic cells and tissues from the GalT —/— pigs were characterized by an analysis of the expression of Galα-1,3-Gal (α-Gal) epitope. Briefly, ear fibroblast cell lines of 19 homozygous GalT —/— pigs were established and cryopreserved. The expression of α-Gal epitope in the cells was measured by fluorescence activated cell sorter (FACS) analysis using BS-I-B4 lectin. Also, the homozygous (GalT —/—) cells and tissues samples were immunostained with BS-I-B4 lectin for analysis of α-Gal epitope expression. The results showed that the expression of α-Gal epitope in GalT —/— cells (0.2 %) were significantly (p< 0.05) down-regulated to the range of cynomolgus monkey fibroblast (0.2 %) cells compared to heterozygous (GalT —/+) (9.3 %) and wild type (GalT +/+) (93.7 %) fibroblast cells. In the immunostaining results, while the expression of α-Gal epitope was detected a partly in GalT —/+ cells and mostly in GalT +/+ cells, it was almost not detected in the GalT —/— cells. Also, immunostaining results from various tissues of the GalT —/— pig showed that the expression of α-Gal epitope was not detectable, whereas various tissues from GalT +/+ pig showed a strong expression of α-Gal epitope. Our results demonstrated that α-Gal epitope expressions from GalT —/— pigs were successfully knocked out to prevent hyperacute immune rejection for further study of xenotransplantation.

This study compared the effects of the initial head position (i.e., a HHP versus a relaxed head position) of subjects with and without a FHP on the thickness of the deep and superficial neck flexor muscles during CCF. The study recruited 6 subjects with a FHP and 10 subjects without a FHP. The subjects performed CCF in two different head positions: a HHP, with the head aligned so that the forehead and chin formed a horizontal line, and a relaxed head position (RHP), with the head aligned in a self-selected comfortable position. During the CCF exercise, the thickness of the longus colli (LCo) and the thickness of the sternocleidomastoid (SCM) were recorded using ultrasonography. The thickness of each muscle was measured by Image J software. The statistical analysis was performed with a two-way mixed-model analysis of variance. The thickness of the SCM differed significantly (p<.05) between the subjects with and without FHP. According to a post hoc independent t-test, the change in thickness of the SCM increased significantly during CCF in the subjects with FHP while adopting a HHP compared to that in the subjects without FHP. The change in thickness of the SCM was not significantly different between the two positions in subjects without FHP, and there was no significant change in thickness of the LCo muscle during the CCF exercise according to the initial position in both subjects with and without FHP. The results suggest that CCF should be performed in RHP to minimize contraction of the SCM in subjects with a FHP.
