This study was carried out to investigate insect community structure from different habitats in Baengnyeong island.We performed day and night collection at two different habitats (mountain, rural area) of Baengnyeong island from Mayto September in 2015. A total of 2,879 individuals of 404 species, 81 families belonging to 10 orders were collectedand identified. A dominant species was Idisia ornata Pascoe (Tenebrionidae) despite a very low percentage (6.04%) ofthe species among the catches. Results of independent t-test showed a significant high (p<0.001) of species richness onmountain. Also, seasonal results of ANOVA (Analysis of variance) were significantly influential with species abundanceand species richness. The result of NMDS analysis showed that the community structure of the insects from the mountainis different with rural area.

The continuous exploration in deep seawater from Korea makes us lead the discovery of ancient Chlorophyta, Palmophyllum, in the Korean coast. The phylogenetic analyses of 18S rRNA and rbcL genes demonstrate that our specimens are Palmophyllum crassum (Naccari) Rabenhorst, recorded in Japan and clearly distinguished from P. umbracola from New Zealand and California, USA. Palmophyllum crassum grows in the subtidal region, 8-30 m deep, and has a crustose thallus which is closely adherent to substrates such as non-geniculate crustose coralline algae, sponge, shells, or rocks. P. crassum is composed of numerous spherical cells embedded in the gelatinous matrix. The discovery of this ancient green seaweed implies that the Korean coast is one of the hotspots of algal species diversity and has the suitable marine environment for algal speciation. We suggest the grounds to conserve the Korean coast environmentally as the biodiversity center of marine species by studying the phylogeny of seaweeds.

Social media play a role in the value that sneakerheads, individuals who collect, wear, and trade sneakers with extraordinary effort and resources, place on specific brands and models of sneakers. In-depth interviews with 25 sneakerheads, recruited through sneakerhead online communities and snow-ball sampling, were conducted to explore how social media contribute to emotional and monetary value creation of sneakers, as well as how social media is used across the Inventory Ownership Cycle (IOC) which includes pre-acquisition, acquisition, physical possession, and disposal of sneakers (Boyd & Mcconocha, 1996). Finding shows that during the pre-acquisition stage, emotional and monetary value is constructed when brands post images of celebrities wearing new models on various social media sites. Hype initially created by the brand is perpetuated by posts and conversations among sneakersheads. Perceived higher levels of hype lead one to believe demand surpasses supply, and therefore, monetary values of specific models increase. Through social media, consumers research and gauge the value not only of soon to be released sneakers, but also previously released sneakers only available on the resale market. During the acquisition stage, the online environment has become increasingly important. To avoid issues associated with selling high-demand/low-supply sneakers in- store, such as violent incidents and dishonest employees, many retailers have shifted sales of such product to online formats (Dunne, 2014). Social media serves as a platform for sneakerheads to learn about dates and locations of new releases and to locate resellers from whom they can purchase previously released sneakers. During the physical possession stage, sneakerheads engage with community members via social media; they show off their sneaker collections, as well as to obtain and share information regarding sneaker customization and maintenance to preserve aesthetics and value. It is through the engagement with fellow sneakerheads and the sneakers within their personal collections that emotional value can be further constructed. During the disposal stage, social media is used by resellers to determine monetary value, identify and communicate with potential buyers across the nation, and complete resale transactions. In summary, this research demonstrates how sneakerheads use social media throughout the IOC, as well as the role social media plays in the construction and identification of sneaker value.

Multiple interferon tau (IFNT) genes exist in bovine. An antiluteolytic substance secreted by the bovine conceptus and primarily responsible for maternal recognition of pregnancy is bovine trophoblast protein 1 (bIFNT1), a new type I interferon tau (IFNT) genes. The objectives of this research were to investigate whether multiple, distinct gene encode bIFNT1 and other type I bIFNT gene in the bovine genome and to examine expression of bIFNT1 and other bIFNTc1 mRNAs during conceptus development. These transcrips could be regulated through caudalrelatedhomeobox-2 (CDX2) and ETS2 and/or AP1 (JUN) expression, a transcription factor implicated in the control of cell differentiation in the trophectoderm. The presence of mRNAs encoded by bIFNT1 and type I bIFNTc1 genes were examined quantitatively via reverse transcription-polymerase chain reaction (RT-PCR) analysis of total cellular RNA (tcRNA) extracted from on day 17, 20 and 22 bovine conceptuses. The expression level of bIFNT1 was higher on day 17 transcripts were gradually weakly detectable on day 20 and 22. However, the other bIFNTc1 gene examined transcripts was highly expressed on day 20 and transcripts were weakly detectable on day 17 and 22 bovine conceptuses. Furthermore, human choriocarcinoma JEG3 was co-transfected with an -1kb-bIFNT1/c1-Luc constructs and several transcription factor expression plasmids. Compared to each -1kb-bIFNT1/c1-Luc increased when this constructs were co-transfected with, ETS2, AP1(JUN), CREBBP and/or CDX2. Also, bIFNTc1 gene was had very effect on activity by alone ETS2, and AP1 (JUN) expression factors in choriocarcinoma JEG3 cell. However, bIFNT1 gene expression of the upstream region was not identified. We demonstrated that the activities of bIFN genes are regulated by differential, tissue-specific and developmental competence during pregnancy.

We present the results of BV time-series photometry of the globular cluster NGC 288. Ob- servations were carried out to search for variable stars using the Korea Microlensing Telescope Network (KMTNet) 1.6-m telescopes and a 4k pre-science CCD camera during a test observation from August to December, 2014. We found a new SX Phe star and confirmed twelve previously known variable stars in NGC 288. For the semi-regular variable star V1, we newly determined a period of 37.3 days from light curves spanning 137 days. The light-curve solution of the eclipsing binary V10 indicates that the system is probably a detached system. The pulsation properties of nine SX Phe stars were examined by applying multiple frequency analysis to their light curves. We derived a new Period-Luminosity (P-L) relation, hMV i = −2.476(±0.300) logP − 0.354(±0.385), from six SX Phe stars showing the fundamental mode. Additionally, the period ratios of three SX Phe stars that probably have a double-radial mode were investigated; PFO/PF = 0.779 for V5, PTO/PFO = 0.685 for V9, PSO/PFO = 0.811 for V11. This paper is the first contribution in a series assessing the detections and properties of variable stars in six southern globular clusters with the KMTNet system.

This study investigated the antidiabetic effect of amaranth grain ethanol extract (AEE) in a diabetic animal model, db/db mouse. The mice were divided into 4 groups: normal control mice (C57BL/6J), diabetic mice (C57BL/6J db/db), diabetic mice fed a lower concentration of AEE (0.3 mg/kg), and diabetic mice fed a higher concentration of AEE (0.5 mg/kg). After 10 weeks of treatment, body weights, blood insulin levels and blood glucose levels of each group were compared. At the end of treatment, the results showed that both AEE supplemented groups had lower body weights than those in the diabetic groups although higher than those in the normal groups. Moreover, in both AEE supplemented groups, serum insulin levels were higher and blood glucose levels were lower than those in the diabetic groups although both values were higher than those in the normal groups. The results of this study suggest that AEE can alleviate many of the common symptoms of diabetes in diabetic mice and, therefore, has potential as a therapeutic supplement for normalization of blood glucose and insulin levels in humans.

A recent study reported that Pleurotus ostreatus has the potential to be used as a β-glucan-based cream for supportive complementary therapy of atopic dermatitis. KH054 is a new herbal prescription consisting of P. ostreatus and Panax ginseng. The effects of atopic dermatitis-induced materials on the expression of cytokine genes in human monocytes (THP-1, EoL- 1) have been examined. Some reports demonstrated that P. ginseng augments the activity of natural killer cells, which plays an important role in innate immunity against infection and tumor development. Monocyte chemotactic protein 1 (MCP-1), interleukin (IL)-6, and IL-8 have important roles in mediating the infiltration of various cells into the skin of atopic dermatitis and psoriasis. The present study investigated whether KH054 on induced IL-6, IL-8, and MCP-1 secretion by house dust mite (Dermatophagoides pteronissinus) in THP-1 (human acute monocytic leukemia) and EoL-1(Human eosinophilic leukemia) cell. D. pteronissinus functions in the pathogenesis of allergic diseases, including atopic dermatitis and asthma. The inhibitory effect of KH054 on the induction of IL-6, IL-8, and MCP-1 secretion by D. pteronissinus extract in THP-1 and EoL-1 cells was examined. KH054 potently suppressed the elevated production of IL-6 and IL-8 induced by D. pteronissinus treatment in THP-1 and EoL-1 cells. Based on the present results, KH054 may be useful for developing functional foods to treat atopic dermatitis.

Interferon tau (IFNT), produced by the mononuclear trophectoderm, signals the process of maternal recognition of pregnancy in ruminants, but its expression in vivo is not well characterized. Objectives of this study were to determine IFNT gene isoforms expressed in the bovine uterus, and to identify differences in promoter sequences of IFNT genes that differ in their expression. Through the RNA-seq analysis of bovine conceptuses on days 17, 20 and 22 (day 0 = day of estrus), the expression of only two IFNT transcripts, IFNT1 and IFNTc1, were found, which were indeed classified into the IFNT gene clade. IFNT mRNAs were highest on day 17, and then decreased on days 20, and 22, which were also supported by the results of quantitative RT-PCR. Bovine ear-derived fibroblast (EF) cells were then cotransfected with luciferase reporter constructs carrying 5‘-upstream (positions -1000 to +51) regions of IFNT1 or IFNTc1 and various transcription factor expression plasmids. CDX2, either alone or with other Ap-1, ETS2 and/or CREBBP transcription factors, was found to increase luciferase activity approximately 10 and 18 fold more than twice of those cotransfected with bIFNT1, c1-Luc construct. Furthermore, The degree of transcriptional activation by a combination of the AP1, ETS2, CREBBP and/or CDX2 expression vectors was similar to that of CDX2 along plasmid. However, expression patterns of these Luc activity differented. Whereas bIFNTc1-Luc showed lowest antivity had than bIFNT1-Luc reports. Although, lowest antivity had of the bIFNTc1 –Luc report, cotransfected with the bIFNTc1-Luc construct and AP1(JUN) or/and ETS2 expression plasmid, Luc activity was enhanced approximately 2 and 4-fold more than the bIFNT1-Luc. Furthermore, along CDX2 expression factor had high effect on activity of bIFNT1-Luc reporter than the c1 gene in EF cells. These results suggest that two forms of IFNT genes are expressed in utero and their transcriptional regulations differ.

Pine wilt disease (PWD) is one of the most important forest tree diseases, especially in the East Asian countries of Japan, China, and Korea. The Japanese pine sawyer, Monochamus alternatus Hope, is the PWN vector for Japanese red pine and Japanese black pine while Monochamus saltuarius Gebler is the vector for Korean white pine. Various control methods, such as aerial pesticide applications, biological control using parasitoids and fumigant such as methyl bromide are used. But the PWD still has spread. Therefore, we were selected effective aerial insecticides. Susceptibility of M. saltuarius and M. alternatus adults were investigated using 9 insecticides which are available in the market in Korea. And then, we tested them to the Apis mellifera to vertify the environmental impact.

Monochamus saltuarius is one of the insect vector of pine wilt disease with Monochamus alternatus. The present study aimed to investigate the dose to induce sterile and the effect of sterility according to the gender of M. saltuarius. As the electron beam irradiation dose increased, the hatchability, adult eclosion rate and longevity of the former mid and late maturation feeding stage of adults was slightly reduced. However, there was no difference between these two adults. In addition, female adults were more sensitive to the electron beam than the male adults. Hatchability of the F1 generation of ♂T × ♀N o r♀T × ♂N (T: 200 Gy electron beam irradiation, N: 0 Gy) was completely suppressed. As electron beam irradiation dose increased, the fecundity of female adults were slightly decreased. Results by comet assay showed that electron beam irradiation induced as dose increased DNA damage in M. saltuarius adults. These results suggest that SIT using electron beam may be useful for control of M. saltuarius.

To obtain information on the sanitary of indoor environment in greenhouses used for shiitake cultivation, bacteria associated with larvae and imagoes of Sciaridae flies, pest to shiitake mushroom, were isolated and identified. A total of 1,048 bacterial colonies were isolated from the flies’ larvae and 984 bacterial colonies were isolated from the flies’ imagoes. Based on molecular analysis of the 16S rDNA sequence, Achromobacter xylosoxidans and Tetrathiobacter kashmirensis of β-proteobacteria, Enterobacter asburiae and Raoultella ornithinolytica of γ -proteobacteria, Curtobacterium sp. and Microbacterium thalassium of Actinobacteria, and Penibacillus taichungensis of Firmicutes were identified from the colonies of the flies’ larvae. While, Bacillus megaterium, B. thuringiensis, Lysinbacillus sphaericus and L. fusifomis of Firmicutes, Microbacterium thalassium and Citricoccus parietis of Actinobacteria, and Enterobacter asburiae of γ-proteobacteria were identified from the flies’ imagoes. Some of the isolated bacterial species were known be human pathogens. Overall, the results of this study suggested that mushroom fly carrying human pathogenic bacteria is one of sources impact on the sanitary of indoor environment of greenhouses used for shiitake cultivation.
