The number of reported mitochondrial genomes (mitogenomes) from the monotypic Lasiocampoidea has been limited until recently. In this study, we sequenced the complete mitogenome of the lappet moth, Kunugia undans (Lepidoptera: Lasiocampidae), and compared it to those of other lasiocampid species and macroheteroceran superfamilies (59 species in six superfamilies). The 15,570-bp long K. undans genome had the typical set of genes found in animal mitogenomes, with the exception of one additional trnR that are located between trnA and trnN loci. Considering that the two trnR copies are located in tandem with proper secondary structures and identical anticodons, a gene duplication event might be responsible for the presence of the two tRNAs. In summary, the general mitogenome characteristics of Lasiocampoidea did not differ greatly from the remaining macroheteroceran superfamilies, but it did exhibit some unique features.

The spotted-wing drosophila (SWD), Drosophila suzukii (Diptera: Drosophilidae), is an economically damaging pest that feeds on most thin-skinned fruits. In this study, we sequenced portions of the mitochondrial (mt) COI and ND4 genes from a total of 195 individuals collected mainly from Korea. A total of 139 haplotypes were obtained from the concatenated COI and ND4 sequences. A dataset combining GenBank sequences with our own data identified a total of 94 worldwide COI haplotypes with a maximum sequence divergence of 5.433% (32 bp). A rough estimate of genetic diversity in each country showed higher diversity in ancestral distributional ranges, but the invasion over Asian countries seems to have been substantial because haplotype diversity was only 2.35-3.97-fold lower in the USA, Canada, and Italy than that in the populations ancestral ranges.

Insect antennae play important roles in finding mates and in locating food source and oviposition sites. Riptortus pedestris is an important pest of soybean and sweet persimmon in Korea. The male R. pedestris adult produce the aggregation pheromone attracting the conspecific nymphs and both sexes of adults. The pheromone was known as a cue for food finding, but the 1st instar nymph can develop to the 2nd instar without food. This phenomenon may suggest that the 1st instar nymph may have different sensilla system from other instars. Thus, we investigated the morphology and distribution of antennal sensilla and antennal response to the aggregation pheromone (AG) of each nymphal stage using Scanning Electron Microscope (SEM) and Electroantennography (EAG). As expected, first instar nymph did not have sensilla trichodea 3 (T3) and chaetica 3 (Ch3) which existed in other instar nymphs. The antennae of the 1st instar nymph did not responded to AG, with no difference from control. For further elucidation of the functions of sensilla T3 and CH3, single sensillum recording to AG will be done.

This study was conducted to investigate the distributional characteristics of ground beetles and to provide basis information for biodiversity management including the ground beetles in the Naejangsan National Park area. Pitfall traps were installed throughout 20 sites within Naejangsan National Park during 2008 to 2011 to collect ground beetles. A total of 2,409 collected ground beetles were identified with 35 species belonging to 19 genera of 8 subfamilies. Coptolabrus jankowskii jankowskii, Eucarabus sternbergi sternbergi, and Pterosticus audax were dominant at the core area, while Pheropsophus jessoensis, Synuchus nitidus, Synuchus cycloderus, and Chlaenius naeviger were dominant at the border of the National Park and adjacent to the road or grassland. These differences of dominant species also affected to the similarity of species composition between core and border area, and caused increasing dissimilarities between sites with cluster analysis. Although the result of the present study was a case study using ground beetles, it will be helpful to develop a management strategy of biodiversity conservation in Naejangsan National Park and its surroundings.

Spider community was surveyed at Nakdonggang River which is the longest river (525 km and 23,384 km2) located East-south part of Korea. Nakdonggang river is developing for water management and environmental conservation including restoration of river ecosystem under “The Four-River Restoration Project”. Sampling was made 3 occasions from June to August in 2009. Eight survey sites were selected from both sides of river in Andong, Sangju, Gumi and Seongju prefectures. Spiders were collected with sweep net for on the plants above ground and pitfall traps for on the ground. A total of 94 species of 71 genera in 24 families were identified from 805 collected spiders. Species richness was high in Salticidae (18 species, 19.1%), Araneidae (12 species, 12.8%), Lycosidae (9 species, 9.6%) in order. Wandering spiders (55 species occupied 58.5%, 493 individuals occupied 61.2%) were higher than webbing spiders (39 species occupied 41.5%, 493 individuals occupied 61.2%) in species richness and abundance. Dominant species were Tetragnatha praedonia (Tetragnathidae) and Neoscona adianta (Araneidae) in webbing spiders, and Anahita fauna (Ctenidae), Pirata procurvus (Lycosidae) and Gnaphosa kompirensis (Gnaphosidae) in wandering spiders with abundance. Collectively, most spiders collected from this study were water preferring spiders and showed different community structure compared to other reports from terrestrial spider fauna. Present result will bevaluable to compare the effect of development on the arthropod fauna after completion of the project.

운간초의 분화 품질을 향상시키기 위하여 ‘Kumoma’ 와 ‘Kumoma-Gusa’ 두 품종의 생장과 개화에 미치는 영향을 구명하고자 식물생장억제제 (PGRs) 4종을 처리 하였다. 식물생장억제제 종류와 처리농도는 paclobutrazol (10, 20, 40, 80 mg·L-1), flurprimidol (5, 10, 20, 40mg·L-1), daminozide (500, 1000, 2000, 4000mg·L-1), chlormequat (50, 100, 200, 400 mg·L-1)이고 엽면살포 와 토양관주 방법으로 처리하였다. Paclobutrazol 40 mg·L-1 처리는 운간초의 두 품종에서 초장과 화경 장을 줄이는데 효과적이었다. ‘Kumoma’ 품종에서, paclobutrazol 40 mg·L-1 엽면살포와 토양관주 처리방 법은 초장을 각각 12.6, 12.5 cm로, 화경장은 3.4, 3.3 cm로 줄일 수 있었다. ‘Kumoma-Gusa‘ 품종에서 는 paclobutrazol 토양관주는 처리 농도가 증가함에 따라 초장은 13.2-10.7 cm, 화경장은 3.9-2.0 cm까지 줄일 수 있었지만 꽃의 수는 대조구와 비교했을 때 현 저하게 감소하여서 20개까지 감소하였다. Flurprimidol 20mg·L-1 스프레이와 토양관주 처리는 두 품종 모두 초장과 화경장을 줄일 수 있었다. ‘Kumoma’ 품종에 서 flurprimidol 10 mg·L-1 스프레이 또는 토양관주 처리는 개화 품질을 향상시킬 수 있었고 대조구와 비 교해 꽃의 수는 44.7개 이상, 출하 일수는 5일 정도 빨리 출하 할 수 있었다. ‘Kumoma-Gusa‘ 품종에서 PGRs처리에 의한 초장 과 화경장 억제효과가 가장 큰 것은 paclobutrazol 80mg·L-1과 flurprimidol 40mg·L-1 이었고 paclobutrazol 과 flurprimidol 스프레이와 토양관주 처리에서 각각, 초장은 10.7, 9.9 cm, 화경장은 2.0, 1.5 cm 로 생장 억제효과가 가장 큰 것을 알 수 있었다. 그러나 flurprimidol 40 mg·L-1 토양관주 처리에서 출하일수는 농도에 따라 3-13일 정도 대조구보다 늦어졌고 꽃의 수는 15.6개로 가장 적은 것을 관찰 할 수 있었다. 두 품종 모두에서 daminozide 처리는 초장과 화경장 이 줄어들지 않았지만 ‘Kumoma’ 품종에서는 대조구 와 비교했을 때 꽃의 수가 증가하였다. Chlormequat 처리는 paclobutrazol 과 flurprimidol 처리와 비교했 을 때 화경장 감소효과는 작았고 처리 식물의 잎은 다른 처리에 비해 연한 녹색을 보여주었다. 두 품종 모두에서 chlormequat 과 daminozide 처리는 생육과 개화 품질에 효과적으로 영향을 주지는 않았지만 꽃의 수는 모든 처리농도에서 41개 이상을 보여주었고, ‘Kumoma-Gusa’ 품종에 chlormequat 토양관주 처리는 최대 꽃의 수 63개를 볼 수 있었다. 이번 결과들은 paclobutrazol 과 flurprimidol 처리가 운간초 분화의 품질 향상을 위한 화경장의 생육을 조 절하는 생장억제제로서 사용 될 수 있음을 보여 주었 고, ‘Kumoma’ 품종에서는 paclobutrazol 40 mg·L-1 스프레이는 생육특성을, flurprimidol 10 mg·L-1 토양관 주 방법은 개화관련 특성의 품질을 향상시키는 생장억 제제의 농도로 추천 될 수 있고, ‘Kumoma-Gusa’ 품종 에서는 flurprimidol 20mg·L-1 스프레이와 flurprimidol 5mg·L-1 토양관주 방법이 운간초 분화의 생육특성과 개 화품질을 향상시키는 생장억제제의 농도로 추천 될 수 있다.

The growth of the middle school girls show big difference among the individuals and the development of each area of the body is not uniformed but diverse which could be understood as the period that the problems on the fit of the clothes occur extensively. Therefore, in this study, the somatotype of the middle school girls are intended to be categorized for the highly applicable clothes design. For this, the 3 middle schools in Jeonju were selected for anthropometric measurement of 324 middle schools. The items of measurement are related to the somatotype of middle school girls, clothes design which is consisted of total of 50 items. For the basic data of clothes was judged that the classification of somatotype related to the tops and bottoms would be rational; hence, it is classified into the upper part and lower part of the body to extract the body shape consistent factor. As a result of analyzing the factors, the upper body consistent was extracted as the 4 items: upper body circumference, upper body length, breast growth and arm length. It was displayed as 75.26% explicability. The lower body consistent factors are extracted as lower body height, lower body circumference, hip length, and rear shape with 78.62% explicability. To classify the somatotype of upper body and lower body, each factor score is made into the independent viable for group analysis. As a result, the upper body was classified into the 'upper body with small breast and long' and 'upper body with big breast'. The lower body was categorized as 'lower body with long hip length' and 'standard lower body'.

We analyzed a portion of mitochondrial COI gene sequences (658 bp) to investigate the genetic diversity and geographic variation of the swallowtail butterfly, Papilioxuthus L., and the cabbage butterfly, Pieris rapae (Lepidoptera: Papilionidae). P. xuthus showed a moderate level of sequence divergence (0.91% at maximum) in 15 haplotypes, whereas P. rapae showed a moderate to high level of sequence divergence (1.67% at maximum) in 30 haplotypes, compared with other relevant studies. Analyses of population genetic structure showed that most populations are not genetically differentiated in both species. The distribution pattern of both species appears to be consistent with category IV of the phylogeographic pattern sensu Avise (Avise et al. 1987): a phylogenetic continuity, an absence of regional isolation of mtDNA clones, and extensive distribution of close clones. The observed pattern of genetic diversity and geographic variation of the two butterfly species seems to reflect the abundant habitats, abundant host plants, and flying abilities in connection with the lack of historical biogeographic barriers.

We determined the complete mitochondrial genome (mitogenome) of the Japanese Oak Silkmoth, Antheraea yamamai (Lepidoptera: Saturniidae) from two overlapping fragments and subsequent shotgun sequencing. The 15,601-bp long A. yamamai mitogenome contains gene arrangement and content identical to the most common arrangement found in lepidopteran insects. Most individual A. yamamai mitochondrial (mt) genes were well within the range found in the respective genes of other insects, except for small ribosomal RNA (1,037 bp). The 336-bp A+T-rich region is relatively smaller than that of other lepidopteran insects. The region is interesting in that it contains tRNA-like structures as found in the A+T-rich regions of other insect mitogenomes. The start codon of A. yamamai COI gene is unusual in that no typical one (ATN) is available. Three of the 13 protein-coding genes have incomplete termination codon T or TA. All tRNA formed stable stem-and-loop structure, except for tRNASer(AGN), the DHU arm of which formed a simple loop as seen in many other metazoan mt tRNASer(AGN).

A solitary fibrous tumor (SFT) is a rare mesenchymal neoplasm that was first documented in pleura, but ubiquitous in nature, involving extrapleural sites such as the upper respiratory tract, mediastinum, head and neck. To date, about 21 cases of SFT of the breast have been reported. Herein, we presented a 60-year-old Korean female with a palpable mass in the left breast. Ultrasonography with near-oval shape, and well-circumscribed margins suggested a benign lesion, so complete resection was performed. With immunohistochemical staining, we could obtain a definitive diagnosis. Since some SFTs have unpredictable clinical course, long-term follow-up is needed for all patients.

본 연구는 의료용 선형가속기 시설을 차폐하는 콘크리트에 대한 중성자 방사화 연구로써, 일반 콘크리트 와 저 방사화 콘크리트를 비교 분석하였다. 실험 방법은 MCNPX (Ver. 2.5.0)와 FISPACT-2010를 사용하여 모의실험을 진행하여, 광자선과 중성자선에 대한 차폐능을 산정하고 중성자 방사화 평가를 진행하였다. 그 결과 차폐능은 일반 콘크리트에서 20~50 ㎝ 효율적이였으며, 방사화 평가의 경우 저 방사화 콘크리트에서 방사능이 낮게 계산되었으나, 모두 자체처분허용 농도를 초과하지 않는 수준으로 산정되었다. 이를 종합적 으로 분석한 결과 일반 콘크리트를 사용하는 것이 효율적인 것으로 판단된다.

Background: Mahonia Nepalensis DC. (Hoang lien o ro), the specie of the family Berberidaceae, is widely distributed in the high mountainous areas at altitudes 1700 – 1900 m of Vietnam. It is found that the stem of Mahonia nepalensis indicated anti-inflammatory, anti-bacterial and antifungal activities and they are used particularly for the treatment of eczema, psoriasis, and other skin conditions. However, no study on the antioxidant and anti-cancer activities of Mahonia Nepalensis stem has been previously reported. The aim of this study was to evaluate anti-oxidant and anti-cancer activities of Mahonia Nepalensis stem. Methods and Results: The stem pieces of Mahonia Nepalensis were dried and extracted three times with 100% methanol. After that, the extract was suspended in distilled water and then partitioned with n-hexane, ethyl-acetate (EtOAc) and butanol (water saturated BuOH) fractions were then evaporated using a vacuum rotary evaporator. Evaluation of the anti-oxidative activity of Mahonia Nepalensis was carried out using a DPPH (2,2-diphenyl-1-picrylhydrazyl) radical-producing system. The results revealed that the ethyl acetate fraction of M. nepalensis possessed higher potential DPPH radical scavenging activity (IC50, 81.88 ± 1.33㎍/㎖) than other fractions as well as BHT (2,6-Di-tert-Butyl-4-methylphenol) (IC50, 250.49 ± 1.60㎍/㎖). The reducing power assay was also investigated and EtOAc fraction showed higher absorbance values than other fractions. At 1.0 mg/ml concentration, EtOAc fraction showed absorbance of 1.72, be higher than Ascorbic acid. Cell viability was evaluated according to the MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyl tetrazolium Bromide) assay. By MTT assay, all fractions showed a significant reduction in cell viability on COLO 205 (Human colon carcinoma cell) at the highest concentration tested (200㎍/ ㎖) with over 70% decrease in cell viability was obtained, and the highest significantly inhibiting effect occurred in butanol fraction with approximately 90% reduction in cell viability. Conclusion: We demonstrated that Mahonia Nepalensis stem extract has highly potential in anti-cancer activity. Further studies are necessary in order to explore the variety of Mahonia Nepalensis stem to be applied as a valuable natural material.

This study was conducted to investigate the antibacterial, antioxidant, and in vitro greenhouse gas mitigation activities of fermented Scutellaria baicalensis Georgi extract. Seven starter cultures were used, comprising four of lactic acid bacteria and three of Saccharomyces cerevisiae. Ten grams of S. baicalensis Georgi powder was diluted in 90 mL autoclaved MRS broth. Each seed culture was inoculated with 3-10% (v/v) S. baicalensis Georgi MRS broth and incubated at 30℃ for 48 h. Among the starter cultures used, only Lactobacillus plantarum EJ43 could withstand the fermentation conditions. This fermentation broth was dried and extracted with ethanol to assess its antibacterial, antioxidant, and in vitro methane mitigation activities. The extract of S. baicalensis Georgi fermented by L. plantarum EJ43 (SBLp) showed higher antibacterial activity (bigger clear zone) compared to the unfermented S. baicalensis Georgi extract (SB0). SBLp also presented 1.2 folds higher antioxidant activity than SB0. During in vitro rumen fermentation, SBLp showed reduction in methane production compared to SB0 or the control. In conclusion, fermentation by L. plantarum EJ43 may enhance antibacterial and antioxidant activities of S. baicalensis Georgi and decrease enteric methane production.

기미는 몇몇의 병인학적 요인을 갖고 있지만, 많은 연구가 멜라닌 형성에 집중되어 있다. 본 연구에서는 멜라닌 형성과 구별되는 혈관의 감소에 의한 기미의 개선을 보고자 하였다. 피부과 전문의의 육안평가를 통해 기미와 일광 흑자를 가진 한국 여성 20명을 대상으로 실험을 진행하였다. 연구 대상자는 8주 간 기능성 화장품 을 사용하였다. Chromameter 기기로 측정한 연구 대상자의 기미 병변, 일광 흑자 병변 및 정상 피부 부위에서 의 각 피부색 측정 결과를 분석하였다. 시료 사용 8주 경과 후, 기미 병변 부위의 피부색 밝기와 적색도가 정상 피부 부위에 비해 통계적으로 유의하게 개선되었다. 또한, 기미 병변 및 일광 흑자 병변 부위의 피부색 밝기의 개선 정도는 유사하였다. 그러나, 시료 사용 8주 경과 후 기미 병변 부위의 적색도가 일광 흑자 병변 부위에 비해 통계적으로 유의하게 개선되었다. 본 연구에서는 기능성 제품을 사용함으로써 기미 병변 부위에서 피부색 밝기 뿐만 아니라 적색도 또한 개선됨을 확인하였다. 이에 적색도가 기미 병변 부위의 평가를 위한 부가적이고 적합한 요인이 될 수 있음을 제시하고자 한다.

Background : Ixeris genus has been used in traditional medicines as stomachics, sedatives, and diuretics. Ixeris dentata var albiflora is a kind of perennial herbaceous plant and one of the plants of the genus Ixeris (Asteraceae). It is well-known for edible wild vegetable in Korea, China, Japan, and Mongolia. Specially, Korean has its root and young leaf with appetizing vegetable due to bitter taste. Methods and Results : We isolated 8 genes that are involved in carotenoid biosynthesis using the Illumina/Solexa HiSeq2000 platform. In this study, a full-length cDNA clone encoding phytoene synthase (IdPSY), phytoene desaturase (IdPDS), ξ-carotene desaturase (IdZDS), lycopene β-cyclase (IdLCYB), and zeaxanthin epoxidase (IdZEP) and partial-length cDNA clones encoding lycopene ε-cyclase (IdLCYE), ε-ring carotene hydroxylase (IdCHXE), and β-ring carotene hydroxylase (IdCHXB2) were identified in I. dentata. The theoretical molecular weight (MW) and isoelectric point values of 8 genes were investigated. Sequence analyses revealed that these proteins shared high identity and conserved domains with their orthologous genes. IdPSY, IdPDS, IdZDS, IdLCYB, IdCHXB2, and IdZEP were constitutively expressed in the roots, stems, leaves, and flowers of I. dentata. Conclusion : Our study on the biosynthesis of carotenoids in I. dentata will provide basic data for elucidating the contribution of carotenoids to the considerable medicinal properties of I. dentata.

Background : Haskap berries commonly refer to fruits of Lonicera caerulea L., recognized by the Japanese aborigines as the “The elixir of life.”. Due to their recent arrival on the North American market, haskap berries have not yet been positioned among other berries and compared in terms of their phytochemical content. And haskap berries have higher ascorbic acid and anthocyanin content than other berries known for their health-promoting benefits, such as blueberries. However, no study has reported on the antioxidant and anti-cancer activity of Lonicera caerulea stem. The purpose of this study is to present the current research on the chemical content, antioxidant and anti-cancer activities of Lonicera caerulea stem. Methods and Results : The stem of Lonicera caerulea L. ware dried in the shade at room temperature and extracted with 100% methanol. The extract was suspended in deionized water and partitioned sequentially with n-hexane, chloroform, ethyl-acetate and butanol (water saturated BuOH) fractions. Antioxidant activities were measured by determination of antioxidants, DPPH (2,2-diphenyl-1-picrylhydrazyl). Cell viability was determined by the MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide] assay. All cell lines were purchased from the Korean Cell Line Bank (Seoul, Korea). All results were performed with three replications were processed statistically. By DPPH assay, the Lonicera caerulea L. the highest activity was obtained from the ethyl-acetate fraction (IC50=15.46 ㎍/㎖). By MTT assay, the chloroform fraction showed a significant growth inhibiting effect on MCF-7 (Human breast cancer, IC50=225.91 ㎍/㎖), COLO 205 (Human colon cancer, IC50=179.55 ㎍/㎖), but on AGS (Human stomach cancer) and other fractions it did not show effect. Conclusion : We demonstrated that Lonicera caerulea L. stem extract and fractions has antioxidant and antiproliferation activity in vitro. Further studies should identify the active constituents in Lonicera caerulea L stem to evaluate the potential in vitro antioxidant and antiproliferation activities of the extract.

Background : Astilboides tabularis (Hemsl.) Engl. is a perennial herbaceous plant, distributed in the northern high mountains of the Korean peninsula and China. It is an excellent ornamental plant currently at risk of overharvesting and therefore, is designated as an endangered wild plant Class II by the Ministry of Environment. Physiological research on A. tabularis has not be reported. Therefore, in this study, using A. tabulari extracts, antioxidant and Anti-inflammatory effects were determined. Methods and Results : The antioxidant and free radical scavenging activities of A. tabularis extracts were evaluated using DPPH (2,2-diphenyl-1-picrylhydrazyl) assay. The results showed that the ethyl acetate fraction of A. tabularis possesses potent DPPH radical scavenging activity (2.90±0.08㎍/㎖), similar to the scavenging activity of ascorbic acid (2.19±0.06㎍/㎖), and better than the powerful antioxidant α-tocopherol (10.60±0.40㎍/㎖) as well as BHA (butylatedhydroxy anisole)(6.12±0.27㎍/㎖). The ethyl acetate fraction possessed a significantly higher concentration of total phenolic (549.70±2.72㎎GAE/g) and flavonolic content (154.58±1.04㎎QE/g). It was also found that the ethyl acetate fraction exhibited high reducing power and inhibition of ROS (Reactive Oxygen Species) formation. Different fractions of A. tabularis were tested for anti-inflammatory activity using LPS stimulated Raw 264.7 cells. The n-hexane and ethyl acetate fractions exhibited a high inhibitory effect on NO (Nitrite oxide) production (22.43±1.06%, 19.30±0.45%, respectively) at 200㎍/㎖ concentration. The mRNA of IL-1β, iNOS and COX-2 gene expression was decreased by treatment with the ethyl acetate fraction. These results showed that A. tabularis extracts can be used as natural substances to control inflammation. Conclusion : These result showed that A. tabularis extracts can be used in a variety of antioxidant and other functional product research and development processes as valuable natural materials.
