This study started with the issue that the criteria for the general image scale used in outdoor color planning are vague and the vocabulary and expressive area of the scale are not accurate. As an exterior color planning guideline, it is required to suggest a sensible image scale, which is an appropriate assessment tool for outdoor environment. We identified psychological attributes of colors and set the color image scale axis as “Soft–Hard” in a vertical and “Warm–Cool” in a horizontal. 26 sensibility languages were finally selected for the image scale through literature review, pre-analysis, and expert evaluation. All types of colors extracted from analyzing over 600 photo images were categorized according to 26 sensibility languages. 3 colors by each sensibility language were finally selected and arranged in the color image scale in accord with the outdoor environment of the apartment houses. The significance of this study is that wide range of color position in the color image scale could be utilized as an effective guideline for actual color planning by upgrading the existing color image scale to a higher level with the color reflecting sensibility language. The result also implies that the development of diversified color palette is required especially for the exterior color planning of apartment houses, and the systematical color design process should be established in order to improve the quality of color environment.

Background : The natural stable isotope ratio of common bio-elements like carbon (C), nitrogen (N), oxygen (O), or sulfur (S) varies with diverse isotope fractionation processes in nature. Therefore, measuring the variation of these stable isotope ratios in ginseng roots can be a feasible tool to discriminate the geographical origins of ginseng in Korea. Methods and Results : The 3-year-old six Korean ginseng cultivars were cultivated at the five regions in Korea, and then used for measuring the stable isotope ratios of C, N, O, and S by isotope ratio mass spectrometry (IRMS). The mean C, N, O, and S stable isotope ratio values in the ginseng roots significantly differed according to the cultivation regions (p < 0.05). However, these isotope ratios in ginseng roots had relatively weak discriminative power against to the ginseng cultivars at each cultivation region. The interaction of the cultivation region and ginseng cultivar type also significantly affected to the C, N, O, and S stable isotope ratio in ginseng roots (p < 0.0001). The two-dimensional plots associated with the N stable isotope ratio can effectively separate the ginseng roots in Jinan compared to those in the other regions. The partial least squares-discriminant analysis showed more significant separation between ginseng geographical origins compared to the principal component analysis. Conclusion : Our findings improve our understanding of how the isotope composition of ginseng roots varies with respect to cultivation regions and cultivars, and suggest that the analysis of the stable isotope ratios combined with chemometrics can be used as a feasible tool to discriminate geographical origin of ginseng in Korea.

Background : ROS produced by oxidative stress damaged endothelial cells, and cause a variety of vascular complications. In diabetic hyperglycemia state, ROS increase. The polyol pathway occur in diabetic complications, the excess glucose is absorbed into the polyol pathway when aldose reductase increased, NADPH changes it to sorbitol. Glutathione (GSH) removes ROS. GSH level is reduced by glutathione reductase, using NADPH as an electron donor. Activation of the polyol pathway decrease NADPH, and GSH also reduced. As a result, ROS is increased. In diabetic hyperglycemia state, Glycolysis increases. Effects of increased glycolysis, protein kinase C (PKC) is increased. NAD(P)H oxidase, stimulated by PKC-dependent pathway, increases ROS in the cell. In this study, we measured the ROS scavenging activity of 5 natural products (Lycii fructus, Astragalus membranaceus, Cassia Tora, Polygonatum odoratum, Rubus Coreanus), to confirm the efficacy as diabetic antioxidants. Methods and Results : We extracted 5 natural product by distilled water and ethanol. DPPH radical scavenging activity was significantly higher in Lycii fructus, Rubus coreanus. ABTS radical scavenging activity was better Rubus coreanus, Lycii fructus, Cassia Tora. In addition to, Rubus coreanus, Cassia Tora, Lycii fructus was comparatively higher reducing power activity than other natural products. And total phenolic and flavonoid contents were much higher in Rubus coreanus compared with other extracts. Conclusion : These results suggest that Lycii fructus, Rubus coreanus can be applied as diabetic antioxidant that prevent vascular complications caused by ROS.

In this study, genetic diversity of wild Codonopsis lanceolata collected in Korea were analysed using SSR makers. Wild C. lanceolata roots were collected in Jeollanam-do Jangheung-gun Choentae Mountain as in roots. The wild C. lanceolata plants were cultivated in Chungbuk National University greenhouse and the leaves were sampled from 36 plants. The genomic DNA of C. lanceolata was extracted using CTAB. PCR was performed using a program of 35 cycles at 94℃ for 30 sec, 60℃ for 30 sec, and 72℃ for 30 sec with an pre-denaturation of 94℃ for 5 min and a final extension of 72℃ for 30 min. The PCR reaction mixture contains 5 pmole of primers and 20 ng of DNA template in a 20 μL reaction volume. The genotype of the analyzed samples were very different. Therefore, the wild C. lanceolata collected in Korea look genetically diverse.

Codonopsis lanceolata is a perennial climber. The roots are used as medicinal materials or vegetables. Recently, demand for C. lanceolata is increasing as a healthy food. C. lanceolata is distributed in India and East Asia such as China, Japan as well as Korea. In South Korea, this plant is widely cultivated in Gangwon-do province. No C. lanceolata varieties were developed in Korea. The objective of this study is to analyze genetic diversity of C. lanceolata cultivated in Korea using SSR makers. C. lanceolata roots were collected in each region were cultivated in Chungbuk National University greenhouse. Samples were obtained from fresh leaves of 5 plants from each collection region. The genomic DNA was extracted using CTAB. Genetic diversity was analysed using 4 sets of C. lanceolata SSR makers. PCR was performed in total 20 μL reaction volume containing 20 ng of DNA template, 5 pmole of primers. The genotypes of the analyzed samples were very similar. That means that the genetic diversity of C. lanceolata cultivated in Korea is very low.

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.

Orchardgrass (Dactylis glomerata L.) is a Gramineae perennial grass species and commonly used as a forage crop and developed to be used for pasture. In Korea, in order to improve high persistence and forage quality, through selection of various superior parental varieties for breeding and synthesis of them with new lines, there are ongoing worldwide studies aiming to enhance the quality and environmental adaptability of Orchardgrass. Between 2010 and 2014, a Orchardgrass variety named Onnuri 2ho was developed by the Grassland & Forages Division, National Institute of Animal Science, Rural Development Administration (RDA), Republic of Korea. For the production of synthetic seeds for Onnuri 2ho 4 superior clones, Dg7506, Dg9508, Edg215 and Edg218 were selected and polycrossed. Between 2010 and 2011, the agronomic growth characteristics and forage production capability of the seeds were studied at Cheonan, and between 2012 and 2014, regional trials were conducted in Cheonan, Hoengseong, Jinju, and in Jeju. The main growth characteristic of Onnuri 2ho is a tetraploid variety, a medium-late maturity variety, the heading stage of which is around May 17, which is four days later than that of Amba. This study tested the regional adaptability of Orchardgrass in Cheonan, Hoengseong, Jeju, and in Jinju. The average dry matter yield of Onnuri 2ho in the four regions was 15,814 kg/ha, which is greater than that of Amba by 34%. These differences show that Onnuri 2ho is more resistant to environmental stresses than Amba and that this growth characteristic directly led to dry matter yield. Thus, Onnuri 2ho is a suitable variety for the establishment of grasslands as it has enhanced disease resistance and persistence, compared to Amba. The forage quality of Onnuri 2ho was similar to that of Amba in crude protein (11.5%), total digestible nutrients (59.2%), neutral detergent fiber (62.7%), and acid detergent fiber (37.6%), whereas the forage quality of Ongreen was higher than that of Amba in (71.0%). The new variety was selected and named Onnuri 2ho from Composite 34 by the RDA in November 2014, and the application for the protection of the new variety by the Korea Seed and Variety Service is currently pending. In this study, a new variety of Orchardgrass with excellent environmental adaptability was developed, in order to contribute to the vitalization of the Korean grassland industry.

Rice is one of the most important cereal crops in the world and a model plant for functional genomics of monocotyledon. Recently, rice crop loss is estimated to be approximately 30% of the total yield due to herbivorous pests, mainly insects. Cry1Ac toxin is a protein produced by the bacterium Bacillus thuringiensis and has insecticidal properties. CryBP1 toxin also is an insecticidal protein produced by the bacterium Bacillus popilliae. These two toxic genes derived bacteria, which were inserted into a binary vector, have been introduced into rice plants by Agrobacterium tumefaciens mediated transformation in order to enhance resistance to insects. Here, we utilized anthers to regenerate transgenic rice plants when it has been plated on the callus induction media as a callus-inducing material. Anther culture has a benefit in terms of being apt to produce doubled haploids in short term in plants breeding compared to seed culture. However, anther culture method in generating transgenic rice still has low productivity of plant regeneration in some genotypes of Japonica rice. Therefore, we examined the efficiency of callus induction and transformation with three different cultivars of Japonica rice, Haiami, Ungwang and Dongjin. In this study, our results showed that Haiami is the best genotype among three cultivars of Japonica rice as callus inducing material in anther culture to produce transgenic rice plants conferring resistance to insects.

Neutropenic enterocolitis (NE), the most serious gastrointestinal complication, has been reported as a clinical syndrome that occurs in the setting of disease- or chemotherapy-induced neutropenia. Complications of NE include bowel necrosis with perforation, fistula, stenosis, massive bleeding, abscess formation, and pneumatosis intestinalis (PI). Most physicians recommend initial conservative management with bowel rest, intravenous fluids, total parenteral nutrition, broad-spectrum antibiotics, and normalization of neutrophil counts. Surgical intervention is recommended in the event of obstruction, perforation, persistent gastrointestinal bleeding despite correction of thrombocytopenia and coagulopathy, or clinical deterioration. We experienced a patient whose abdominal computed tomography scan showed pneumoretroperitoneum, intramural gas in the colon, and inferior vena caval gas. Her condition improved after treatment with granulocyte colony-stimulating factor and broad-spectrum antibiotics. We report on this case along with a review of the literature.

Ultrastructural characteristics of the germ cells and accessory cells in testis during spermatogenesis and taxonomic values of mature sperm morphology of Ruditapes philippinarum were investigated by the transmission electron microscope and scanning electron microscope observations. The testis is the diffuse organ that consists of branching acini containing developing germ cells and accessory cells associated with spermatogenesis. The morphology of the spermatozoon is of the primitive type and is somewhat different to those of other bivalves. The morphologies of the sperm nucleus type and the acrosome shape of this species have a cylinderical type and a modified cone shape, respectively. As some ultrastructural characteristics of the acrosomal vesicle, the peripheral parts of two basal rings show electron opaque part, while the apex part of the acrosome shows electron lucent part. These characteristics of sperm belong to the family Veneridae in the subclass Heterodonta, unlike a characteristic of the subclass Pteriomorphia showing all part of the acrosome being composed of electron opaque part. In particular, a cylinder-like nucleus of the sperm is curved. The spermatozoon is approximately 48-51 μm in length, including a long acrosome (about 2.40 μm in length), a curved sperm nucleus (about 3.40 μm in length), and a tail flagellum. The axoneme of the sperm tail shows a 9+2 structure.

“Onnuri” is a new orchardgrass(Dactylis glomerata L.) variety developed by the National Institue of Animal Science (NIAS) in 2011. To develope the new variety of orchardgrass, 5 superior clones were selected and polycrossed for seed production. Agronomic growth characteristics and forage production of “Onnuri” were examined at Cheonan from 2009 to 2011, and regional trials were conducted in Cheonan, Pyungchang Jinzu and Jeju from 2009 to 2011, respectively. “Onnuri” showed medium type growth habit in fall and spring and medium in length of flag leaf and long upper internode. Plant height of “Onnuri” was more than 10cm that of standard variety, “Amba” and heading date was 5 days earlyer than 16th May compared to Amba. Characteristics such as waterlogging, disease resistance of “Onnuri” were stronger or better than those of Amba, specially “Onnuri” showed 18% higher dry matter yield (14,775kg/ha) compared to Amaba(12,523kg/ha). Nutritive value was appeared to be similar in both varieties.

Italian Ryegrass is a high productivity and feed value, and an upright grass that behaves like a biennial or short-lived perennial. It grows vigorously in winter and early spring. Italian ryegrass and a related species, perennial ryegrass, Lolium perenne, are the two common weedy ryegrassses. Italian ryegrass and perennial ryegrass can hybridize, resulting in offspring that are difficult to identify as either species. Ryegrasses are cultivated for turf and forage. Sometimes Italian ryegrass is grown as cover crop. It has the potential to produce high yields and, with proper management, can be high quality with good animal performance. To develop of a high quality, productivity and early variety, 20 varieties examined growth and yield characteristics. The heading date of Green farm with high cold tolerance was on 28 April. Most of Introduced varieties except Grazer have mid and late heading date.
