Raphiolepis indica (R. indica) is one of evergreen shrubs belonging to the Rosaceae and is grown wildly in Jeju. This study was performed to evaluate the hepatoprotective effect of different fractions (n-hexane, dichloromethane, ethyl acetate, butanol, water) from R. indica. Anti-oxidative effects were determined using 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging activity and total phenol contents. Hepatoprotective effect was identified by 3-[4, 5-dimethylthiazol-2-yl]-2, 5-diphenyltetrazolium bromide (MTT) assay in Huh7 cells. Among various fractions, ethyl acetate and butanol fractions showed the lowest DPPH remained rate reaching approximately 78.7 and 65.5% at 400 μg/mL. Ethyl acetate and butanol fractions showed the total phenolic content at 164.5 and 137.3 mg GAE/g extract. The ethyl acetate and butanol fractions were resistant against oxidative stress in MTT assay and showed higher hepatoprotective effect than other fractions. Therefore, these results suggest that the ethyl acetate and butanol fractions of R. indica might have therapeutic value in liver damage.

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.

We have analyzed the transcriptome of Scolopendra subspinipes mutilans using RNA sequencing and identified severalantimicrobial peptide candidates. Among the peptides, named scolopendrasins, were selected based on the physicochemicalproperties of antimicrobial peptides via an in silico analysis. As a result, we evaluated the antimicrobial activities ofscolopendrasins against Gram positive and negative bacteria including Candida albicans by radial diffusion assay and colonycount assay. We also investigated the cytotoxicity of scolopendrasins through hemolysis assay. We found that the actionof scolopendrasins involved binding to the surface of microorganisms via a specific interaction with lipopolysaccharides,lipoteichoic acid, and peptidoglycans, which are components of the bacterial membrane. These results will provide a basisfor developing therapeutic agents such as peptide antibiotics.

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.

The mesenchymal stem cells (MSC) has been investigated as a source of stem cell therapy to replace and treat damaged cells. Human endometrial epithelial and stromal cells was isolated from hysterectomy tissue and the direct evidence of stem/progenitor cells in the human endometrium was identified. Endometrium derived stem cells (EnMSCs) are known to have a high proliferative ability, genetic stability, lack of tumorigenicity and low immnunogenicity during long-term cultivation. Here, we aimed to identify MSC in canine endometrium and characterize its potential to differentiate into decidua cells. EnMSCs were isolated from thrown-away spayed uterus of adult canine depending on their estrus cycle, and identified by flow cytometry, immunocytochemistry and flow cytometry with MSC specific markers. We then characterized the ability of EnMSCs by the doubling-time analysis, colony-forming units and MSC differentiation assays. Isolated EnMSCs expressed stem cell specific genes (Sox2, Oct4, Nanog, MCAM, Endoglin, Susd2 and IGTB) and MSC surface markers (CD90, CD44 and CD117). EnMSCs are also differentiated into adipogenic, osteogenic and chondrogenic cells morphologically under modified conditions with the expression of lineage specific genetic markers. EnMSCs showed higher proliferation ability than canine amniotic fluid derived MSCs which were used as a positive control. EnMSCs were cultured at low density (10, 20, cells/cm2) and initiated to form small colonies of loosely-arranged cells and gradually formed large colonies of densely-packed cells which underwent self-renewal with high proliferative potential which is similar to the clonogenicity feature of human endometrium-derived stem cells. EnMSCs were then induced to differentiate into decidua cells with 0.5 mM dbcAMP. After 14 days, EnMSCs changed their morphology into the elongated and rounded shape. The induced decidual cells expressed PRL and IGFBP1 which are typically expressed in decidua cells. In conclusion, we successfully isolated and characterized MSC in the canine endometrium which differentiated into decidua cells. These results showed that endometrium may be a promising source of stem cells, and furthermore raise the possibility of canine EnMSCs as a novel hypothetical decidualisation model of infertility associated with decidualisation insufficiency and implantation failure.

The nesting behavior, reproduction, fruit set and shape of O. cornifrons varied significantly with the released sex ratio of O. cornifrons. A female : male sex ratio of 1 : 2 was resulted in a 3.4 to 6.7 fold higher than other sex ratio in a nesting behavior. A ratio of 1 : 2 resulted in a 1.2-fold nesting rate, which was slightly higher than other nesting rates. Releasing only males resulted in a 2.4-fold greater amount of fruit set in non-pollinated sites. A sex ratio of 1 : 2 gave a slightly higher shape index and a 1.2 to 1.6-fold lower asymmetric index than other sex ratios. There was no significant difference between female release numbers in fruit set, and 100 to 200 females gave a slightly higher shape index than 400 females. Thus, we determined that 200 females should be released per 2,000㎡ and that the sex ratio of females to males should be 1 : 2.

Somatic cell nuclear transfer (SCNT) has been considered for preserving genetically valuable or endangered animals. Sapsaree is a Natianal Monument in Korea to maintian a pure pedigree. The aim of this study was to produce azoospermia Sapsaree using SCNT and identify normal reproductive ability of cloned azoospermia Sapsaree. Ear skin biopsy was performed on a thirteen-year-old azoospermia Sapsaree and ear skin fibroblasts were isolated for SCNT as donor cells. The fibroblasts were injected into enucleated in vivo matured oocytes, the couplets were electrical fused by two pulse of direct current (55 V for 15 μs) using titanium and platinum fusion needle and activated by calcium ionophore. Cloned embryos were surgically transferred into oviducts of natuarally estrus cycle synchronized recipient dogs. The fusion rate of platinum needle was 70%, which was higher than those of titanium needle (64.1%). Developmental rate to the 8 cells and 10 cell stages was higher in platinum needle group (24% and 16%, respectively) than those of platinum needle group (14.8% and 3.1%, respectively). Total 35 SCNT embryos were transferred into oviducts of 3 recipient dogs and one recipient finally delivered a puppy by caesarean section. As results, this study demonstrated that platinum fusion needle could be successfully make the reconstructed embryos and improve the efficiency of canine SCNT. Cloning azoospermia Sapsaree may contribute to conserve genetically valuable and unique pedigree. And further study should be confirm whether cloned live dog is azoospermia.

The cancer and Parkinson's disease associated protein DJ-1 is multifunctional protein that involves in diverse cellular process. DJ-1 protein has a cellular protective role and promoted cell survival under an oxidative stress. However, the cellular protective mechanism of DJ-1 is not fully understand, and we needs to be further study their functions in novel organisms. In the present study, we investigated the protective role of DJ-1 against induced oxidative stress in canine cell line. On the basis of these experiments, canine DJ-1 overexpressing and null cell lines were established. The stable overexpression and down regulation of DJ-1 efficiency confirmed by the western blot analysis. Subsequently, the DJ-1 gene transfected cell lines and control cells were subjected to induced the oxidative stress, and then cell viability, cell proliferation assay, cellular apoptosis detection analysis (Annexin V and TUNEL assay), intracellular ROS and mitochondrial activity were measured appropriately. The results showed that DJ-1 overexpressed cells were up-regulated cell viability under oxidative stress conditions induced by the rotenone and hydrogen peroxide (H2O2), whereas loss of DJ-1 cells were down-regulated the cell survival activity. Additionally, overexpression of DJ-1 cells increased cell resistance to oxidative stress and inhibited the elevation of cell death and cellular ROS induced apoptosis. Moreover, DJ-1 overexpressed cells was increased mitochondrial functions by using confocal microscopy with MitoTracker staining. On the contrary to this, DJ-1 null cells show defective cellular protection and mitochondria activity against oxidative stress conditions. Our data indicate that canine DJ-1 protein attenuates cellular apoptosis and ROS generation, enhances the cellular survival activity and promote mitochondrial function under the oxidative stress, likewise other mammalian cells. Importantly, DJ-1 overexpression may be an important part of a protective strategy as a sensor for oxidative stress.

We investigated pollination and foraging activities of honeybee (Apis mellifera L.) and bumblebee (Bombus terrestris L.) during flowering season of the asian pear (Pyrus pyrifolia N.) under different weather conditions. There was no significant statistical difference about the pollination activities of two species. However, the pollination activities of bumblebee were more active than those of honeybee under low temperature and rainfall period. The activities of honeybee and bumblebee were more influenced by temperature than other factors (i.e. illumination and wind velocity). Honeybee was more sensitive to temperature and illumination than bumblebee. At low temperatures (<20℃) on cloudy days (<30,000 lux) with a certain wind velocity (>4.0 m/s), the pollination activity of the honeybee was lower twice than that of bumblebee.

Distillers dried grain (DDG) and makgeolli spent grain (MSG) are agricultural by-product to produce alcoholic beverage. However, they are known to contain enough nutrients. Mealworm is a promising insect resource for an animal feed ingredient as well as alternative human food. With low cost, DDG and MSG were investigated as a feed ingredient for rearing high quality mealworms. DDG and MSG were mixed with wheat bran and compared to control feed (only wheat bran) for its effects on larval survivorship, larval weight, duration for larval development, pupation rate, and pupal weight. Adding DDG on wheat bran showed positive results for larval weight, duration for larval developmental period, and pupation rate. However, adding MSG made longer duration for larval development, but it also improved larval weight, pupal weight with more than 90% pupation rate. We confirmed that adding 30～50% of DDG or MSG to conventional wheat bran have a strong potential to replace the conventional wheat bran insect feed for quality insect production.

Bees of the genus Osmia are cavity-nesting solitary species that play important roles as pollinators. Nest traps are one of the most common methods to study Osmia bees. To elucidate the optimal environmental conditions of nesting sites, we investigated the effects of location, direction, altitude, and sites of nest traps on the rate of trap-nesting Osmia spp. During the collection period, the average rate of trap-nesting Osmia spp. collected within 90 days after the installation of traps was 17.0±20.0%. This percentage was 2.7-fold higher than that of trap-nesting bees in 30 days after the installation of traps. The Jeongseon location exhibited the highest rates of trap-nesting Osmia spp. collected in 30 and 90 days, representing 11.1 ±17.6% and 23.2±22.5%, respectively. The direction of the nest traps did not affect the rate of trap-nesting Osmia spp. The altitude ranges of the traps were 0-199 m, 200-399 m, 400-599 m, 600-799 m and over 800 m. Interestingly, the altitude range of 600-799 m showed the highest rate of trap-nesting bees, which was 40.4±3.9%. Higher altitudes seemed to correspond to higher rates of trap-nesting bees. With regards to the sites where the nests were placed, the rate of trap-nesting bees in a mud wall of an old house was 45.1±25.2%, which was 3-fold higher than that of a nest in an apple orchard. The flowering plants collected at different locations during the trap-nesting activity of Osmia bees belonged to 18 families and 34 species. In conclusion, the rates of trap nests colonized by Osmia spp. were affected by altitude, site, and plant diversity.

Insect is an important player in the ecosystem as a prey for animals. Moreover, they are a valuable candidate food source for rearing animal. Tenebrio molitor (Coeloptera: Tenebrionidae) larvae are known as a good food source with high protein, unsaturated fatty acid, minerals. Therefore, it has strong potential to substitute the conventional meat consumption. To utilize T. molitor as a feed, the standard mass-rearing protocol is required. To make standard mass-rearing protocol, we tested different temperature(17.5, 20, 22.5, 25, 27.5 and 30°C) conditions for egg, larvae, pupae and adult T. molitor to identify the optimal rearing condition. Hatching was occurred within 15~32.5°C range. However, 17.5~27.5°C was required to get more than 70 % hatching rete. When the eggs were treated in 22.5~27.5°C, all eggs were hatched within 10 days. As larval development, shorter developmental period, higher pupation and eclosion rates were observed within 25~27.5°C temperature range. In addition, we compared the number of egg, oviposition duration and time required to start egg-laying. The minimum egg-laying(258.40±10.86) was observed at 17.5°C, but the maximum(749.10±7.45) was at 27.5°C. The maximum oviposition duration (137.00±12.73 day (mean±S.D.)) was achieved at 27.5°C, but the minimum (87.50±3.54 day (mean±S.D.)) was at 30°C. The time required to start egg-laying was less than 10 days at 17.5, 27.5, and 30°C. To consider all the factors, we concluded that the optimal temperature is 27.5 °C.

This study is to assist in developing creative designs based on the humor available in the fashion world of Moschino. For the research method, this writing examined literature on humor and Moschino's fashion world and analyzed Moschino's fashion collection, show window, Maison Moschino, and collaborative products to conduct an empirical analysis of humor shown to the fashion media. The research results are as follows. The humor in Moschino's fashion appeared in the form of surrealistic humor with the depaysement technique, deconstructive wit in clothing, such as distortion, change, or exaggeration, and textual humor, including brand symbols, logos, and graffiti. Collection pieces indicated the brand's confirmative identity based on humor with the surrealistic depaysement technique and deconstructive wit through irregular phenomena, such as change, distortion, exaggeration, and illusion in clothing form. Additionally, such attributes added to Moschino's wit and humor in decorative costume components as graphic images, graffiti, and brand symbols, including smile, love, and reversal. The show window display delivered surprises and smiles through the production of surrealistic space borrowed from various objects. In particular, performance with surrealistic images helped to show the characteristics of parodic humor. Maison Moschino was a surrealistic space for the concept of the fairy tale and for practical experience, thus working as a communication channel for humor and emotion. Collaborative products also clearly reflected the identity of the designer's own humor, which showed scarcity value as well as differentiation.

This study aims to integrate sports uniform design into fashion as an effective communication means by analyzing the uniforms of women's pro basketball and volleyball teams in the country. As part of the research method, a literature review was conducted on the domestic pro sports background and women's basketball and volleyball uniforms. For empirical research, an analysis was performed of the uniforms of 12 teams in total: six women's pro basketball teams and six women's pro volleyball teams in the 2013~2014 league. The following results were obtained. First, in terms of formativeness, sleeveless shirts and shorts are basic in both basketball and volleyball. However, there are remarkable differences between the two. Shirts in volleyball are tighter, with the body figure visible, and shorts are shorter in length than those in basketball. Most basketball uniforms have a V-neckline and are collarless, while volleyball uniforms have a standup collar in all teams. Second, both basketball and volleyball apply the representative color of the sponsoring company and the team's typical color, but common colors, such as blue, navy, and white, are used in many teams, which fails to represent a uniquely differentiated image. Third, the logo or symbol of a sponsor is excessively applied to both basketball and volleyball uniforms. This downgrades the uniform's own esthetic features. Fourth, a fashionable uniform design, that reflects the bodily characteristics of women and the characteristics of the sports game would be a beneficial communication tool for all the tiers to become involved in participation and entertainment.

This work aims at analyzing the comparative feature about female flight attendant uniform designs of Korean and Asian region low cost carriers and providing some basic materials for development of these airline companies. As a research method, examinations were carried out on attendant's uniform both theoretically and empirically. Comparison of uniforms was made among the five Korean carriers and ten typical Asian carriers for empirical research. Results showed the followings. First, all Korean low cost carriers were characterized as formal style except Jin Air. Unlike this, Asian low cost carriers appeared as diverse including formal, semi formal, and casual styles with a uniquely differentiated image. Second, all carriers applied their own symbolic color to their uniform. Third, logo or symbol was adopted as a pattern on scarf in the two Korean companies but it didn't take effect practically. For those Asian carriers, embroidery was used on jacket, jumper and collar. They utilized even a merchandising character to put emphasis on airline image. Fourth, diverse petty items with a decorative effect were used in the case of Korean low cost carriers. In the changing period of uniform, nothing much was changed and remained almost the same as before. Those in the Asian region were characterized with the smallest number of items and the preclusion of decorative add-ons on uniform.

본 연구는 갈색거저리(Tenebrio molitor)의 사료로 주로 이용되는 밀기울을 대체할 사료원료 개발을 목표로 수행되었다. 대체원료로서 열풍 건조시킨 귤껍질, 배추, 새송이버섯 및 팽이버섯 폐배지를 사용하였으며, 투여 후 유충의 생존율, 유충 무게, 유충의 발육기간, 용화율, 용무게를 측정하였다. 귤껍질과 배추를 첨가한 배지는 대체 먹이로 적합하지 않았다. 새송이버섯 폐배지의 모든 실험군에서 유충의 생존율은 대조군과 비 슷하였으나 유충의 무게는 대조군에 비해 다소 낮게 나타났고, 유충 발육기간은 폐배지의 함량이 높아질수록 길어짐이 관찰되었다. 팽이버섯 폐 배지 20~50% 첨가 조건에서 대조군과 비슷한 유충 및 용무게가 측정되었으며, 계대사육시 밀기울 사료에 40~50% 팽이버섯 폐배지를 첨가하 는 것이 용화율을 고려했을 때 가장 효과적일 것으로 분석되었다. 결론적으로, 팽이버섯 폐배지를 40%~50% 첨가한 조건에서 기존의 밀기울 사 육법과 비슷한 높은 효율성을 나타내기 때문에 팽이버섯 폐배지는 갈색거저리 유충의 대체사료로서 적합하다고 사료된다.

The spotted-wing drosophila (SWD), Drosophila suzukii (Diptera: Drosophilidae), was originally observed in a few Asian countries, but is now found even in North America and Europe. Genetic information on geographic variation and relationship may broaden our understanding of origin and migration. As a first step, in this study, a portion of mitochondrial COI gene was sequenced to understand genetic relationship and diversity in Korea. Sequencing of 104 individuals provided 57 haplotypes, with the maximum sequence divergence of 1.5%, suggesting high haplotype diversity and moderate sequence divergence. Comparison to GenBankregistered D. suzukii haplotypes (possibly from Spain, Portugal, USA) has shown 100% sequence identity to most of the haplotypes found in this study, but two USA sequences were found to be independent haplotypes, with the sequence divergence ranging from 0.5% ~ 1.4% from our samples in the 553-bp comparison. Phylogenetically, no separable group was found, but, population genetically, the only Chinese population, Sandong, was significantly differentiated (p < 0.05) from all Korean populations, without sharing any haplotype. Among 28 pairwise comparisons of Korean populations only two comparisons showed a significant genetic differentiation, indicating that no population in Korea is completely isolated. Geographically, one haplotype (SWDBA06) was relatively widespread (five among nine localities) and a few haplotypes were found in more than one locality, but most haplotypes were restricted in a locality as a single individual. Overall, high rate of per generation female migration (Nm = 0.75 ~ infinite) and low level of geographic separation (FST=0~0.40) among localities were characteristic. Current data is limited mainly to Korean localities, thus, an expanded study may provide further scrutinized analysis for the fly.
