The changes in extreme daily rainfall totals in Punjab Province, Pakistan, during the period (1981- 2014) are examined in this study. The analysis was focused on the extreme annual and monthly rainfall events, by processing the exceeding of the daily rainfall over various thresholds, which are indicators for the incidence of extreme rainfall events. To analyze the changes in extreme rainfall events and trends of the time series of the annual number of extreme rainfall days (%) the thresholds of 30mm and 50mm has been estimated. Evidence from the twelve stations considered shows that there is an increase in annual number of extreme rainfall days (%) in dataset. These changes of heavy and extreme rainfall events pronounce significant environmental consequences which cause considerable impact on society.

Background : To evaluate the quality of Glycyrrhizae radix (licorice), a popular herbal medicine in Korea, it is necessary to investigate the component profiles of the Glycyrrhiza species distributed in Korean market. Specifically, to control the quality of Korean Glycyrrhizae radix preparations including raw materials, glycyrrhizin (> 2.5%) and liquiritigenin (> 0.7%) has been used as a standard marker compound in Korea Food and Drug Administration (KFDA). To the best of our knowledge, there have been only a few studies regarding the fingerprinting techniques and metabolomics approach of the phytochemicals in Glycyrrhizae radix in Korean market. Therefore, it is necessary to develop a validated method for botanical raw material (BRM) standardization. Methods and Results : Twenty-one Glycyrrhizae radix (G. glabra, G. uralensis, and G. glabra × G. uralensis) were analyzed by UPLC-QTOF-MS and were estimated to statistical and multivariate analysis. Large scale multi-targeted metabolic profiling and fingerprinting techniques were utilized to access a broader insight into the chemical composition of Glycyrrhiza species. The UV/VIS spectra, and MS data (accurate mass and fragmentation pattern in negative mode) of the components in the BRM of G. glabra, G. uralensis, and G. glabra × G. uralensis (incorporation and hybridization) were analyzed with multivariate analyses. Interestingly, UPLC-QTof-MS derived PCA analysis and fingerprinting techniques was found to be effective techniques in the classification of species based on genetic and/or geographical origins. In addition, the revealed metabolite markers could be utilized as a guidance for the BRM standardization as well as a database for quality control of commercial products containing Glycyrrhizae radix. Conclusion : From the above results, the revealed metabolite markers could be utilized as a guidance for the BRM standardization as well as a database for quality control of commercial products containing Glycyrrhizae radix.

To characterize the female or male transcriptome of the Pacific abalone and further increase genomic resources, we sequenced the mRNA of full-length complementary DNA (cDNA) libraries derived from pooled tissues of female and male Haliotis discus hannai by employing the Iso-Seq protocol of the PacBio RSII platform. We successfully assembled whole full-length cDNA sequences and constructed a transcriptome database that included isoform information. After clustering, a total of 15,110 and 12,145 genes that coded for proteins were identified in female and male abalones, respectively. A total of 13,057 putative orthologs were retained from each transcriptome in abalones. Overall Gene Ontology terms and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways analyzed in each database showed a similar composition between sexes. In addition, a total of 519 and 391 isoforms were genome-widely identified with at least two isoforms from female and male transcriptome databases. We found that the number of isoforms and their alternatively spliced patterns are variable and sex-dependent. This information represents the first significant contribution to sex-preferential genomic resources of the Pacific abalone. The availability of whole female and male transcriptome database and their isoform information will be useful to improve our understanding of molecular responses and also for the analysis of population dynamics in the Pacific abalone.

We present extra-tidal features of spatial configuration of stars around three metal-poor globular clusters (NGC 6266, NGC 6273, NGC 6681) located in the Galactic bulge. The wide-field photometric data were obtained in BVI bands with the MOSAIC II camera at CTIO 4 m Blanco telescope. The derived color-magnitude diagrams (CMDs) contain stars in a total 71´×71´area including a cluster and its surrounding field outside of the tidal radius of the cluster. Applying statistical filtering technique, we minimized the field star contaminations on the obtained cluster CMDs and extracted the cluster members. On the spatial stellar density maps around the target clusters, we found overdensity features beyond the tidal radii of the clusters. We also found that the radial density profiles of the clusters show departures from the best-fit King model for their outer regions which support the overdensity patterns.

The English to-infinitive structure has over a dozen different functions, presenting a difficult area for EFL students. The present study shows a relatively dynamic profile of the use of ten to-infinitives functions appearing in EFL children's story writing as the children progress in grade levels and English proficiency—an area that has never been investigated previously. To-infinitives that function as an ‘object’ or ‘purpose’ were most prominent. The students used a higher number of to-infinitives as they progressed from the third to sixth grades. The increase between the four adjacent grade levels did not reach a level of significance, but the increase between middle (third and fourth) and upper (fifth and sixth) levels was significant. The difference was striking when the entire group was re-sorted into lower vs. higher proficiency groups: the increase in the use of to-infinitives was better explained by English proficiency improvement than by grade level progression. This in-depth analysis into the sub-functions adds to the existing knowledge about to-infinitives, which might otherwise remain oversimplified.

In 2013, the Suncheon Bay Garden Expo was successfully accomplished in Korea. This has increased Koreans’ interest in garden and its industry. Although Korea central and local governments make efforts to support the garden industry, there isn’t a sufficient data or statistics for the garden industry and its economic impacts. It is necessary to make a practical and meaningful definition and range of garden industry in Korea. This study is designed to overcome these problems by defining a garden and the garden industry, estimating garden industry’s statistics, and pointing a favorable direction of the industry. According to Huh et al. (2015b), the garden industry is defined with garden material production, garden service and distribution, and garden tourism. Estimating based on this definition and range, Korea’s garden industry generates 1.2 billion dollars in production, 1.5 billion dollars in distribution, and 80 million dollars in tourism (consumption). In total, about 2.7 billion dollars are generated in the garden industry in Korea. I suggest three strategies for a favorable development in Korea garden industry. First, in garden material production, private gardens need management improvement, while public gardens and Korean traditional gardens need government sustainable supports and R&D. Second, in garden distribution, a specific role should be assigned in Korea Agro-Fisheries & Food Trade Cooperation aT Center to connect the garden industry and distribution sectors. Third, a government-leading new industrial strategy should be made to promote consumption and tourism in the garden industry in Korea.

The high quality of gene set is necessary to study the functional research of genes. Although perilla is cultivated as an oil crop and as a vegetable crop in Asian countries such as Korea, Japan, northeast China and Nepal, the reference genome is absent. To assembly perilla gene set, we sequenced the various tissues of perilla (Perilla citriodora) RNA-seq with Illumina HiSeq platform, generating 548,549,314 short reads. When de novo transcriptome assembly was performed with five samples, 86,396 and 38,413 transcripts were assembled as total and representative transcripts, respectively. Using 1,917,424 proteins at Phytozome ver. 9.1, we annotated the perilla assembled transcripts, and 66,139(76.55%) and 24,030(62.55%) transcripts showed the similarity with known plant proteins (E-value < 1e-10) as total and representative transcripts, respectively. Among the diverse molecular functions, we were interested in the regulatory components, such as transcription factor and transcription regulator. Using this data, we identified 499 transcripts annotated the putative transcription factor differentially expressed transcripts. 165 putative transcription factors were significantly expressed in perilla flower and 121 putative transcription factors in both leaf and flower. This study provides the perilla reference gene set and the understanding of the molecular regulation of transcription factor dependent on the tissue.

The roots of Platycodon grandiflorum are known as traditional medicine, has been extensively used since ancient times as a therapeutic to treat cold, cough and asthma in Korean traditional medications. This study was conducted in order to profile proteins from the hormone induced diploid and tetraploid roots using high throughput proteome approach. Two dimensional gels stained with CBB, a total of 64 differential expressed proteins were identified from the diploid root using image analysis by Progenesis SameSpot software. Out of total differential expressed spots, 20 differential expressed protein spots (≥ 2-fold) were analyzed using MALDI-TOF-TOF mass spectrometry whereas a total of 13 protein spots were up regulated and 7 protein spots were down-regulated. However, in the case of tetraploid root, a total of 78 differential expressed proteins were identified from tetraploid root of which a total of 28 differential expressed protein spots (≥ 2-fold) were analyzed by mass spectrometry whereas a total of 16 protein spots were up regulated and a total of 12 protein spots were down-regulated. However, proteins identified using iProClass databases revealed that the identified proteins from the explants were mainly associated with the nucleic acid binding, oxidoreductase activity, transporter activity and isomers activity. The exclusive protein profile may provide insight clues for better understanding the characteristics of proteins and metabolic activity in various explants of the economically important medicinal plant Platycodon grandiflorum.

Panax Ginseng is a perennial medicinal plant originated from North-east asia. Because of its well-known tonic effects mainly from ginsenosides, various types of processed ginseng products have been distributed around the world. Here, we analyzed secondary metabolite profiling of adventitious roots of 5 korean ginseng cultivars, Chunpoong (CP), Sunhyang (SH), Gopoong (GO), Sunun (SU), and Cheongsun (CS). At the same time, the profiles of relative gene expressions related to ginsenoside biosynthesis pathway were compared among ginseng cultivars. Secondary metabolite profiles were revealed by UPLC/Q-TOF-MS from extracts of bioreactor derived adventitious roots of five ginseng cultivars. Using principal component analysis, secondary metabolite profiles of ginseng cultivars were categorized into three groups. Metabolites with high VIP values were annotated using known database and standards compounds. Relative gene expression of ginsenoside related gene were analyzed using realtime PCR. The three groups had distinct metabolite contents. Furthermore, gene expression profiles related to ginsenoside were also different, which might contribute diverse secondary metabolite composition of ginseng cultivars. Further integrated analysis would provide a relationship between genetic background of ginseng cultivars and secondary metabolite profiles.

This study was conducted to construct a DNA marker database for 38 plum varieties collected in Korea using simple sequence repeat (SSR) markers. A set of 61 SSR primer pairs was tested to select polymorphic SSR markers between 8 varieties. Among the 61 primer pairs, 21 showed polymorphism, reproducibility and easy scoring. The genetic relationship between the 21 SSR markers and 38 varieties was analyzed. A total of 210 polymorphic amplified fragments were obtained with the 21 SSR markers. Three to seventeen SSR alleles were detected for each locus, with an average of 10.0 alleles per locus. Average polymorphism information content (PIC) was 0.758, with a range from 0.549 to 0.870. A total of 210 SSR marker loci were used to calculate Jaccard’s distance coefficients for cluster analysis by an unweighted pair-group method with arithmetical average (UPGMA). The genetic distance ranged from 0.06 to 1.00 in 38 varieties. Out of 38 plum varieties, 32 were identified using the 21 SSR markers. Therefore, these SSR markers may be employed to complement distinctness, uniformity, and stability (DUS) tests or as potential tools to solve seed disputes regarding plums.

Numerical Analysis of corrugated-metal culvert is mainly related with corrugated shape, plate thickness, and load transmission mechanism, and these elements especially should be treated consistently in the analysis of 3-Dimensional analysis of behavior of skewed corrugated-metal culvert. And so, the modelling technic, 3-dimensional equivalent plate modelling, is required to be modified.

Reactive oxygen species (ROS) are produced in organisms as the natural products of oxidative metabolism by environmental stress and pathogen invasion. ROS, such as superoxide anion and hydrogen peroxide, can be toxic to cells and tissues to cause oxidative stress. Recent study revealed that olive flounder (Paralichthys olivaceus) superoxide dismutase (SOD) has been identified as a partial gene and strongly induced to benzoin[a]pyrene and it was deduced indicator of aquatic oxidative stress responses, but its transcriptional response against viral infection has not been investigated. In the present study, spatial and temporal expression profile was analyzed to investigate the function of Of-SOD in the anti-viral response. Of-SOD transcripts were ubiquitously detected in diverse tissues with variable levels using a real-time PCR. The expression of Of-SOD was significantly higher in the muscle, liver and brain, but extremely low in the stomach and spleen. Following VHSV challenge, the expression of Of-SOD increased within 3 hours and subsequently decreased to the original level at 2 days post-challenge in kidney. Although expression pattern and induction time are slight differences depending on the tissue, the transcript of Of-SOD was consistently increased in acute infection response, but expression is low in the chronic response. Collectively, Of-SOD expressions were inducible after VHSV infection and they were probably involved in the immune response against viral challenge. These results suggest that SODs may play important roles in the immune defense system of P. olivaceus and perhaps contribute to the protective effects against oxidative stress in this flounder.

This study examined the effects of cage rearing system and backyard raising system on fatty acid profile of egg in laying hens during 9 weeks. Two hundred hens, 70-wk-old, Hy-line Brown, were used in this study and fed basal diets. 100 hens, randomly collected from facility, were transferred to cage rearing system and 100 remaining hens were moved to backyard raising system. For overall period, higher unsaturated fatty acid percentages in two different rearing systems than did saturated fatty acid (SFA) were observed. In unsaturated fatty acid compositions, both rearing system showed a higher mono unsaturated fatty acid (MUFA) contents than poly unsaturated fatty acid (PUFA) contents. Egg quality traits of laying hens reared in backyard system had considerably lower contents of SFA and higher contents of MUFA compared with eggs from cage rearing system (P<0.05). In addition, eggs from cage rearing system resulted in a significantly lower n-3 contents and higher n-6:n-3 ratios and CLA contents in comparison with backyard raising system (P<0.05). However, no significant effects of two different rearing systems on PUFA, PUFA:SFA ratio, and n-6 contents were observed during the experimental period. In conclusion, this result suggests that cage rearing system and backyard raising system will play an important role in improving egg production as functional foods.

본 연구의 목적은 빙해역을 운항하는 선박의 쇄빙시 깨진 해빙에 의해 선수부 좌현 외판에 작용하는 국부 빙하중을 계측한 신호의 특성을 조사하는 것이다. 한국 최초의 쇄빙연구선인 아라온호를 이용하여 2010년 8월초 북극해에서 실선 시험을 수행하여 선수부에 설치된 변형률 게이지로부터 국부적인 빙하중에 의한 신호를 계측하였다. 국부적인 빙하중에 의한 구조 응답 특성을 반영한 계측 신호는 전형적인 유체 충격압에 대한 하중-시간 이력과 다소 다른 특성을 갖는 것도 있음이 파악되었다. 본 연구에서는 계측 신호에 대한 시간 이력을 분석하고, 무차원화된 특성값들로 나타내었다.
