  • Polyploidy has opened a new horizon for selection to sculpt a variety of new gene functions, traits, and lineages. The aim of this study was to investigate the efficacy of the colchicine concentration, temporal changes, and suitable material for inducing effective tetraploid plants of Codonopsis lanceolata. A total of 180 individuals from 16 treatment groups were germinated, and exposed to different concentrations of Colchicine. The plant height of the diploid (18.1 cm) was slightly shorter than that of the tetraploid (13.4 cm). The fresh weight of the main root in the diploid (0.5 g) was 4-fold higher than the tetraploid (2.2 g). The colchicine-treated plant regeneration rate in C. lanceolata was decreased at the elevated concentration of colchicine. A total of 126 individual plants were regenerated in the entire treatment group and tetraploid (2n=4x=32) plants were obtained. In particular, 5 individuals of the tetraploid plant were induced in the 0.05% colchicine for 6h, which is a higher rate (29.4%) than other regenerated plants. As in the seed treatment result, the plant height of the diploid was significantly higher (10.4 cm) than tetraploid. The root length of the tetraploid (10.1 cm) was longer than the diploid, and the root was also thicker. Taken together, the results obtained from the present study may be helpful for the efficient recovery of such polyploid plants through the in vitro application of colchicine, and may improve the productivity and breeding of C. lanceolata.

  • A new Dendranthema grandiflourm 'My Sun' was developed at Gyeonggi-do Agricultural Research & Extension Services (GARES), Korea in 2009. 'My Sun' was initially derived from the cross in 2005 between 'Omega Time Orange', a potted chrysanthemum cultivar with orange single type, and 'Tasman', a potted chrysanthemum cultivar with white single type in 2005. The cultivar has single type flowers with yellow petals. Trial and evaluation was conducted from 2006 to 2009 for the selection of this variety, including a shading culture in spring and a retarding culture in winter. The flowering time of 'My Sun' was October 13th, and year-round flowering is possible by shading or lighting treatment. The diameter of flower is 21.0 mm. Numbers of flowers per stem and petals per flower are 34.4 and 20.4, respectively. Its leaf color was green (Green Group 137A) and plant height was 13.3 cm. Days to flowering under the short day treatment is about 42 in spring, and numbers of branch per plant was 3.4 ea in the winter. This cultivar was resistance to white rust and consumer's preference of new pot-mum is high level than control.

  • In recent years, there has been a significant increase in the number of large-scale projects involving construction, public works and the installation of industrial plants. These projects usually require the participation of a number of public and private entities and involve more than one contract. When disputes arising in connection with these projects are to be submitted to commercial arbitration, the parties often wish to have all disputes decided by one arbitral tribunal, in a single comprehensive proceeding. It has become apparent that the resolution of all major disputes which may arise in connection with such a project in a single comprehensive arbitration proceeding presents a number of advantages. The arbitral institution can provide for a multiparty arbitration proceeding only where all of the parties have agreed to it either at the time the disputes arise or at the time the parties enter into their various contractual arrangement. The discussion about multiparty arbitration centers on the question whether courts should have the power to order the consolidation of arbitration proceedings absent the consent of the parties. As the U.S. Supreme Court has repeatedly denied certiorari to cases presenting the consolidation-question, the conflict between the Court of Appeals' positions remains. The common method of selection in a bilaterial proceeding is the formula by which each party appoints one arbitrator and the two party-chosen arbitrators then mutually agree on a third, neutral arbitrator. This popular method poses, however, both a policy and practical problems In a 3-party-proceeding. It seems that the better solution is to have courts or arbitral institutions appoint all arbitrators for a multiparty proceeding. American courts have employed a variety of methods to appoint arbitrators for multiparty disputes in cases in which the parties had not provided for or could not agree upon a method themselves.

  • Recently, interest in IoT(Internet of Things) technology, which provides Internet services to objects, is increasing. IoT offers a variety of services in home networks, healthcare, and disaster alerts. IoT with LLN(Low Power & Lossy Networks) feature frequently loses sensor node. RPL, the standard routing protocol of IoT, performs global repair when data loss occurs in a sensor node. However, frequent loss of sensor nodes due to lower sensor nodes causes network performance degradation due to frequent full path reset. In this paper, we propose an additional selection method of the storage mode sensor node to solve the network degradation problem due to the frequent path resetting problem even after selecting the storage mode sensor node, and propose a method of equalizing the total path resetting number of each instance.

  • The increase in the consumption of outdoors sportswear is not because of an increase in sales from hiking enthusiasts but rather the general public's desire to wear them as everyday clothing. We expect that the market for the outdoors sportswear will grow gradually as people feel the need to wear extra outerwear for protection from wind everyday. Furthermore, as the consumers' demands for these outerwear increase, their desire for more variety increases as well. Five prominent domestic brands were chosen for the analysis. The selection method included two factors: 1) the brands with the highest sales figures in the last five years 2) brands that were mentioned most frequently in fashion articles (i.e apparel news, fashion biz) from 2009 to 2011. the goal is to analyze each of the brands' different concepts of outerwear design so that the results from the analysis can be used to develop better more diverse products in the market and satisfy with the consumers' need. In the end we have to develop better technology and more diverse designs in order to meet the increase in consumers' need. They are interested in sportswear and functional clothing; we have to satisfy their need. for diverse selections in their outerwear and this is especially the case with consumers in their teens and twenties.

  • Mood classification of blog text is an interesting problem, with a potential for a variety of services involving the Web. This paper introduces an approach to mood classification enhancements through the normalized negation n-grams which contain mood clues and corpus-specific term weighting(CSTW). We've done experiments on blog texts with two different classification methods: Enhanced Mood Flow Analysis(EMFA) and Support Vector Machine based Mood Classification(SVMMC). It proves that the normalized negation n-gram method is quite effective in dealing with negations and gave gradual improvements in mood classification with EMF A. From the selection of CSTW, we noticed that the appropriate weighting scheme is important for supporting adequate levels of mood classification performance because it outperforms the result of TF*IDF and TF.

  • Opera is the most comprehensive musical art. In recent years, contemporary opera worlds has seen a variety of attempts to reinterpret operas of the past in a modern light. This has resulted in a dramatic change in the production of musical style and stage art. The purpose of the study was to modernize and streamline opera costumes by extending the scope of existing stage costume design, through the reinterpretation and application of the decorative elements in the Middle Age of Rococo, such as ruffles, frills, shirring, embroidery, buttons, etc., in such a way as to effectively communicate the moods of an opera to a modern audience. The costumes of the Rococo period were reinterpreted in a modern way, with the following results. First, in this work, the male main character was played by a bass to express the image of an older, lazy, rich man. A key element in modernizing the stage costume was selection of the costume color in such a way as to visually represent the voice tones sung by the major characters in the opera. Second, the maid hat and aprons were decorated with frills by applying the curves of Rocaille decoration from the Rococo period symbolize the role of the maids. This represented the distinction between occupation according to class and status at that time, while also expressing the ideals of modern feminine beauty. This makes for more comfortably-worn costumes, and is economical for production expenses. In the future, the stage costume design for classical opera will need to be revised consideration of a modern viewpoint.

  • The permeate flux decline due to membrane fouling can be addressed using a variety of theoretical stand-points. Judicious selection of an appropriate theory is a key toward successful prediction of the permeate flux. The essential criterion f3r such a decision appears to be a detailed characterization of the feed solution and membrane properties. Modem theories are capable of accurately predicting several properties of colloidal systems that are important in membrane separation processes from fundamental information pertaining to the particle size, charge, and solution ionic strength. Based on such information, it is relatively straight-forward to determine the properties of the concentrated colloidal dispersion in a polarized layer or the cake layer properties. Incorporation of such information in the framework of the standard theories of membrane filtration, namely, the convective diffusion equation coupled with an appropriate permeate transport model, can lead to reasonably accurate prediction of the permeate flux due to colloidal fouling. The schematic of the essential approach has been delineated in Figure 5. The modern approaches based on appropriate cell models appear to predict the permeate flux behavior in crossflow membrane filtration processes quite accurately without invoking novel theoretical descriptions of particle back transport mechanisms or depending on adjust-able parameters. Such agreements have been observed for a wide range of particle size ranging from small proteins like BSA (diameter ${\~}$6 nm) to latex suspensions (diameter ${\~}1\;{\mu}m$). There we, however, several areas that need further exploration. Some of these include: 1) A clear mechanistic description of the cake formation mechanisms that clearly identifies the disorder to order transition point in different colloidal systems. 2) Determining the structure of a cake layer based on the interparticle and hydrodynamic interactions instead of assuming a fixed geometrical structure on the basis of cell models. 3) Performing well controlled experiments where the cake deposition mechanism can be observed for small colloidal particles (< $1\;{\mu}m$). 4) A clear mechanistic description of the critical operating conditions (for instance, critical pressure) which can minimize the propensity of colloidal membrane fluting. 5) Developing theoretical approaches to account for polydisperse systems that can render the models capable of handing realistic feed solutions typically encountered in diverse applications of membrane filtration.
