  • $Cymbidium$ 'Purple Princess' ('Show Girl' x 'Eiko') is a new cultivar having dark purple sepal and petal (RHS, RP59A) with purple lip (RHS, RP59A). A cross was made between pink colored $C.$'Show Girl' as maternal line and dark purple colored $C.$ 'Eiko' as paternal line in 1994. It was preliminarily selected as Line No. 94019267 in 1999 considering the characters of flower shape and color, leaf growing shape and growth habit in normal culture condition. Multiplication, cultivation, and characteristic trials were conducted from 2000 to 2003. The line was named as Wongyo F1-7 and phenotype was characterized in 2004 as a new 'Purple Princess'. 'Purple Princess' has about 13.2 flowers per flower stalk and flower size of 5.2 cm. General appearance of petals and sepals is slightly incurved shape. The plant size is intermediate having erect peduncle. Blooming starts from early December under optimal culture condition. Leaf attitude and twisting is erect and very weak respectively. Erect leaf will be suitable for growing and handling in the nursery as pot orchid flowers.

  • Rapid immunochromatographic assay (ICA) kits were developed using flagella-specific monoclonal antibodies (MAbs) and rabbit polyclonal antibodies for screening Listeria spp. in food. The establishment of different formats, MAb 2B1 as capture antibody and MAb 7A3 or rabbit polyclonal antibodies as detector antibody, was compared. The 2 formats of the ICA kit were shown to have specific reactions with Listeria and no cross-reactivity with any of the non-Listeria including Escherichia coli O157:H7 and Salmonella enteritidis. The detection limits of the ICA kit using the combination of gold-labeled MAb 7A3 and MAb 2B1 showed $1{\times}10^5$ and $1{\times}10^6\;CFU/0.1\;mL$ at 22 and $30^{\circ}C$, respectively. The other format of the ICA kit using the combination of gold-labeled rabbit polyclonal antibodies and MAb 2B1 showed $1{\times}10^6\;CFU/0.1\;mL$ at $22^{\circ}C$ but weak signal at 30 culture. The format utilizing MAb was more sensitive than the one using polyclonal antibodies for capture antibody. Samples contaminated with L. monocytogenes 4b culture (9-10, 5-6, and 1-2 CFU/mL) on pork and pasteurized milk were confirmed as positive results. Current data suggests that this ICA kit is a rapid, simple and effective tool to screen for Listeria spp. in food.

  • This work characterizes 'Yeolha', a new strawberry (Fragaria ${\times}$ ananassa Duch.) cultivar that was released by the Highland Agriculture Research Center, RDA, in 2013. This cultivar originated from a 2008 cross between 'Goha' and 'Elsinyo' and showed excellent ever-bearing characteristics including continuous a flowering habit under long-day and high temperature conditions. It was originally named 'Saebong No. 5' after examining its characteristics and productivity in summer culture from 2010 to 2013. After two regional adaptability tests in 2012, it was selected as an elite cultivar and renamed 'Yeolha'. The general characteristics of 'Yeolha' include a semi-spreading plant type, elliptic leaves, and strong vigor in growth. Its fruit is conical and red. T he s oluble s olids content of 'Yeolha' is 8 .6%, w hich is 0.6% h ig her than t hat of 'Flamenco', b ut f ruit hardness is lower than that of 'Flamenco'. The average fruit weight of 'Yeolha' is about 12.1 g and the marketable yield is $28,133kg{\cdot}ha^{-1}$, which is 117% higher than that of 'Flamenco'. 'Yeolha' is resistant against Fusarium wilt. In addition, 'Yeolha' is suitable for four-season cultivation as a high harvesting cultivar because it shows continuous flowering under long-day and high temperature conditions.

  • Heterogeneity in antigenic composition of Aspergillus fumigatus isolates from clinical specimens and in antibody response of patients infected with this fungus was investigated by immunoblotting. A considerable quantitative and qualitative difference was found in composition of the culture filtrate antigens derived from a reference strain (ATCC 13073) and 8 clinical isolates of A. fumigatus on SDS-PAGE and immunoblots. The crude CF antigen of a strain AFG7 was selected to identify the serologically reactive and specific components by immunoblotting. Out of more than 36 components separated by electrophoresis, transblotted to nitrocellulose sheet, and reacted with sera that showed a positive reaction to A. fumigatus or other fungal antigens on immunodiffusion tests, merely four or so were found useful to serodiagnosis of aspergillosis. An antigen of 82KD was found most reactive and specific component so as to be contained in the standard preparation. Several other components, for example 11KD, 26KD, 30KD and 31KD, also possessed relatively high reactivity and specificity and seemed to be worth while purifying and characterizing. Antibody binding activity (reactivity) of the antigenic components was clearly shown on immunoblots because some were faintly stained with Coomassie blue but darkly stained on immunoblots, while some others behaved contrary to them. A number of components seemed to carry not only species specific but cross reactive antigenic determinants. Immunoblotting proved very useful to identify serologically reactive and specific components that should be present in the antigen to be employed to the serodiagnosis of aspergillosis.

  • In this study, 3D analysis was compared in evaluating the track deformation of subway structures during adjacent excavation. For the 3D analysis model, the boundary conditions of the tunnel model and the application level of the ground water were analyzed as variables. As the result of the effects of track irregularity using the 3D model, the analysis model considering the site ground water level instead of the design values and changing the constraint of the boundary condition is more reasonable. In addition, the influence of track irregularity due to the boundary condition and load condition of the analytical model is more obvious in the factors directly affected by the longitudinal relative displacement of the rail, such as alignment, cross level and gauge irregularity. Therefore, the evaluation on track stability according to adjacent excavation work was appropriate to analysed the longitudinal deformation of the track by using 3D model that could be investigate the deformation of rail. In addition, the boundary condition and load condition(ground water level) of the numerical model was important for accurate analysis results.

  • The purpose of this study is to suggest the desirable direction toward the creative hand-on activities suitable for the characters of the technical high school students by examining the teachers' recognition of sub-factors of creative activities in technical high school and analysing whether the factors are properly utilized. Respondents of this study were 393 teachers at the Technical high school in South Korea. The questionnaire survey on the recognition of creative hand-on activities consisted of questions, which are importance and reflection, from 32 sections in 5 fields. The summary of the results through this study is as following. First, In the results of importance analysis of teachers in technical high school, in club activity field, 'the invention' of 'academic activity', 'film-art' in 'culture-art activity', 'challenge activity' in 'sports activity', 'school specialized major' in 'work practice activity', 'scout federation', 'Red Cross youth activity' in 'youth group activity' were seemed to be higher. Second, In the results of reflection analysis, it was found that the 'academy, culture-art', 'sports activity' fields were similarly reflected in importance thought by teachers in technical high school. However, for 'the work practice activity' and 'youth group activity', except 'the school specialized major', all fields are not properly reflected, independent of importance. For 'the work practice activity', analyses of importance and reflection seemed to be alike but for 'the youth group activity', there was a significant difference between them.

  • This study examines cross-national patterns of asymmetry of marriage tables with respect to educational level and tries to measure the degree of gender inequality across nations. A Primary assumption of the study is that gender inequality inhibits symmetric marriage between men and women. As men and women differ more in status, the rate of symmetric marriage between them declines thus producing asymmetric marriage with respect to social status. More specifically, the main object of the study is to develop statistical models and index with which to assess the patterns and degree of asymmetric marriage. Additionally, it is intended to assess the appropriateness of several theoretical perspectives for explaining these variations identified by the statistical models. Two most important such perspectives are industrialism and theory of politics and culture. To answer these questions, this study relies on twenty-seven marriage tables with respect to educational level, some from published tables, and some extracted from other sources. The main findings of the study are: (1) compared to less industrialized countries, more industrialized countries have lower degrees of asymmetric marriage(gender inequality) with respect to educational level, and (2) other things being equal, differences in politics and culture seem to have the some impact on marriage pattern; for instance, social democracy and state socialism reduce the degree of asymmetric marriage while the high emphasis on gender-based hierarchy in Asian countries seems to increase it In short, these results suggest a weaker or modified version of industrialists That is, while with economic growth most nations show a decline in the degrees of asymmetric marriage with respect to social status, for some nations the degrees of asymmetric marriage are affected by their specific politics or cultures.

  • The mature wheat embryo is arguably one of the best explants for genetic transformation because of its unlimited availability and lack of growth season restriction. However, an efficient regeneration system using mature wheat embryos (Triticum aestivum L.) is still not available. To identify genes related to the tissue culture response (TCR) of wheat, QTLs for callus induction from mature embryos and callus regeneration were mapped using an RIL population derived from the cross of 'Wangshuibai' with 'Nanda2419', which has a good TCR. By whole genome scanning we identified five, four and four chromosome regions conditioning, respectively, percent embryos forming a callus (PEFC), percent calli regenerating plantlets (PCRP), and number of plantlets per regenerating callus (NPRC). The major QTLs QPefc.nau-2A and QPcrp.nau-2A were mapped to the long arm of chromosome 2A, explaining up to 22.8% and 17.6% of the respective phenotypic variance. Moreover, two major QTLs for NPRC were detected on chromosomes 2D and 5D; these together explained 51.6% of the phenotypic variance. We found that chromosomes 2A, 2D, 5A, 5B and 5D were associated via different intervals with at least two of the three TCR indexes used. Based on this study and other reports, the TCRs of different explant types of wheat may be under the control of shared or tightly linked genes, while different genes or gene combinations may govern the stages from callus induction to plantlet regeneration. The importance of group 2 and 5 chromosomes in controlling the TCRs of Triticeae crops and the likely conservation of the corresponding genes in cereals are discussed.

  • A new spray chrysanthemum (Dendranthema grandiflorum) 'Blue Hope' was bred by the Flower Research Institute, Gyeongsangnam-do Agricultural Research & Extension Services in 2009. The cultivar 'Blue Hope' was initially derived from the cross in 2005 between 'Ford', a spray chrysanthemum cultivar, with white anemone type, and 'Chopin', a spray chrysanthemum cultivar with white anemone type. The cultivar has anemone type with white petals. After the evaluation of the characteristics under shade culture in summer and retarding culture in spring and consecutive selection from 2007 to 2009, 'Blue Hope' was selected finality. The natural flowering time of 'Blue Hope' was October 24th, and year-round flowering is possible by shading or lighting treatment. The growth of plant was very vigorous and response time 6.5 weeks. The diameter of flower was 4.9 cm. Number of flowers per stem was 19.1 in autumn. Days to flowering under the short day treatment was about 45 in spring and its vase life was 23.8 days in the autumn season. This cultivar was resistance white rust and consumer's preference of new spray is high level than the control.

  • The word culture itself is very difficult to define. Therefore, in order to confine its meaning, many scholars prefer to attach different prefixes such as inter-, bi-, multi-, cross-, pluri-, trans-, in front of the adjective cultural instead of defining the word culture itself. These prefixes have been used along with about thirty various nouns, ranging from adaptability to training. In this paper, we focused on the adjective intercultural. In fact, this adjective has been widely used, not only in education but also in the communication and philosophy sectors among the world academia discourse. Intercultural Education appeared in America in the 1930s and also in the 1970s in Europe, in order to improve relations between immigrants and the people who received them. Intercultural communication arose in America as a cultural education program for American diplomats and professionals, while interculturalism appeared in the 1970s in Canada as a policy in opposition to multiculturalism. Intercultural philosophy started in 1990s Germany as philosophical speculation against Eurocentrism. As such, the adjective intercultural has been used with a combination of diverse nouns. In regards to this, one can ask the following questions: did the scholars have any kind of agreement during their discussions? Did they communicate and make a positive impact on each other? If not, how can we interpret their common use of the word intercultural? To answer these questions, we tried to compare fives types of intercultural waves of the 20th century, paying particular attention to their time periods, places and backgrounds of appearance, their emphases and shortcomings. Following our research, we found that intercultural waves in the 20th Century have developed independently despite their common use of the word intercultural. Therefore, we concluded that the use of same word intercultural was the result of humankind's effort to approach cultural differences in a positive way in the global village created by internationalization and globalization of the 20th century.
