  • In this study, we performed ovule culture after reciprocal crosses of two Alstroemeria accessions and investigated genetic contribution of parents by using RAPD markers. The best method was half-ovule culture on MS medium supplemented with $60g{\cdot}L^{-1}$ sucrose and $2.2g{\cdot}L^{-1}$ gelrite at 14 days after pollination. Embryos began to germinate after 6 weeks of culture. The complete plantlets were formed after 4 months of culture. In eight progenies and two parental cultivars, 59 polymorphic bands were obtained out of 89 total bands by RAPD analysis using 7 primers. Eight $F_1$ progenies from the crosses between two accessions using reciprocal crosses showed 1:1 contribution of maternal and paternal parents. It is confirmed that $F_1$ progenies were obtained from parental accessions by using RAPD markers. We conclude this cross combination showed pre-fertilization barriers with incompatibility between stigma or style, and pollen because progeny number was different in each cross combination. Thereby, it warrants overcoming pre-fertilization barrier together with post-fertilization barrier in order to broaden the heterozygosity within progeny populations in Alstroemeria breeding program.

  • The Korean wave has become a global phenomenon whose effect has been widely studied in Asia, Europe and the US. However the presumption of cultural distance makes it appear unlikely that the Korean wave could gain traction among African consumers of cultural products. As such, a dearth of evidence exists on the effects of the wave in Africa. This paper examines the effect of the wave in East African countries employing both descriptive and Probit model analyses. The results show that, contrary to conventional beliefs, most Africans surveyed perceive value proximity with Korea through the values conveyed in Korean dramas, movies and music. Confucius values, such as filial piety, family love and respect for the elderly are the most appealing to the East African audience. Importantly, contact with Korean wave contents contributes to the respondents' disposition to form favorable attitude towards Korea. The African consumers of Korea's cultural products are equally likely to purchase other Korean commercial products. These results remotely suggest that Hallyu may be a tool for advancing Korea's soft power towards Africa and could generate positive economic externalities.

  • Since Taquet's first discovery of wild P. yedoensis at Mt. Halla, Korea, in 1908, its morphological chracteristics and question of origin of cultivated yedoensis have given controversies to the botanists. Takenaka, through his experiments on the hybridity of cultivated P. yedoensis, recently holds the opinion that P. yedoensis might have originated in Izu peninsula, Japan. The author presents the summarized report on the wild P. yedoensis and its putative parents based on his 2 years' investigated carried out at Mt. Halla during his breeding experiment of genus Prunus. The species of cherry tree used in the present investigation were identified by Prof. Mankyu Park and Mr. Jonghyu Pu, Korean taxonomists. 1) Wild cherry trees which grow wild in Mt. Halla and whose blooming season is April are mostly P. subhirtella var. pendula form. ascendens and P. donarium P. yedoensis is rare in number, around 10 individuals, having been found in a half century. 2) Individuals of wild yedoensis are variable in some of their morphological characteristics. This is, also, true in other species of Prunus. 3) Wild yedoensis whose vigorous growth, sterility, and rarity in number suggest hybrid origin, has intermediate characteristics between the P. subhirtella and P. donarium. 4) Due to the abnormal weather of the island and various environmental factors such as havbitats, some of the early-blooming subhirtella and late-blooming donarium would bloom at the same time, giving these two species the changes to cross. 5) Wild yedoensis is slightly different in some of its quantitative characters from cultivated species.

  • This study is about the strife patterns in modern fashion and the characteristics inherent in them. The study was aimed at offering the basic materials to develop the creative design that can show various visual expression effects. In terms of method, the study was led by the analysis of documents; domestic and foreign fashion, collection magazines etc were used to analyze the strife patterns in modern fashion. According to the findings, the study used the rearrangement of the strife patterns at the same intervals, the arrangement of different strife patterns within one single item, the hybrid arrangement of strife patterns and different patterns, and the use of strife patterns for a certain part of clothing for the purse of emphasis or decoration. First, the characteristics inherent in such strife patterns showed clear simplicity using the same repetition of simple lines or the two colors of black and white. Second, strife patterns changed silhouettes by causing optical illusion, and showed the rhythm effects, such as swelling, wave or movement by distorting and controlling lines or forms. Third, based on irregular intervals or multi-strife, the concept of unclear disharmony and inconsistency was shown with the beauty of hybridharmony by blending various strife patterns with each other, or strife patterns with different patterns, and thus expressing composite images.

  • What prevails in the today's research on social media is a functional view of technology. Technology is regarded as a set of technical devices used to conduct specific social functions, such as personal communication, social networking, public posting, and corporate advertising, among others. This paper proposes that such a functional view of technology renders social media research unduly limited and constrained in its scope, level, and direction of inquiry. Problematizing on some representative social media research efforts in the field of IS, this paper provides an alternative perspective, that is, to view social media as a technology-for-being that exerts a deeper level of influence on our existence, molding and shaping the nature and mode of being itself. Such a technology-for-being perspective has been rarely explored or subscribed to in the present IS social media research. Building upon the new conception of social media as a technology-for-being, this essay explores the quality of being in the context of social media. Five such qualities are discussed, including virtuality, materiality, externality, liquidity, and hybridity. The essay also explores the deep structural problems of research to guide future social media research. Six of such problems include Problematize-the-Natural, Follow-the-Actor, Welcome-the-Frankenstein, Weber-meets-Frankenstein, Freud-meets-Frankenstein, and Marx-meets-Frankenstein. The essay concludes with discussions on the implications of the essay, its limitations, and suggestions for future work.

  • Objectives : One of the fundamental premises of medical anthropology is the interconnectedness of medicine and society. Recent ethnographies of medicine demonstrate that the interconnectedness of the social and the medical not just evokes relatedness of the two parties, but also emphasizes the agency of the constituents, mutually shaping and being shaped. Against this backdrop, this study attempts to anthropologically investigate Korean medicine in South Korea and traditional Chinese medicine (TCM) in China. Methods : The findings are based on anthropological studies of East Asian medicine employing long-term fieldwork about Korean Medicine and Traditional Chinese Medicine. Results : TCM is characterized by standardization, hospitalization, and scientization, by which simplification, collectivization, and biomedicalization prevail in contemporary traditional medicine in China. In contrast, Korean medicine is characterized by diversity, care delivery by individual private clinics, and a considerable distance from biomedicine. To understand the divergence of the two East Asian medicines, one should consider the social contexts intervening into the medical contents, such as the role of the state and dominant discourses in given historical periods. Conclusions : Korean medicine in South Korea and TCM in China demonstrate well the hybridity of the social and the medical, suggesting that, for more comprehensive understanding of the medical, the social should be paid attention to.

  • Style is considered a pivotal construct in sociolinguistic variation studies. While previous studies have examined style in traditional forms of language such as speech, very little research has examined new and emerging styles such as computer-mediated discourse. Thus, the present study attempts to investigate style in the online communication mode of chat. In so doing, the study compares text-based online chat with speech and writing. Online chat has been previously described as a hybrid form of language that is close to speech. Here, the exact nature of online chat is elucidated by focusing on contraction use. Differential acquisition of stylistic variation is also examined according to English learning background. The empirical component consists of data from Korean speakers of English. Data is taken from a written summary, an oral interview, and a text-based online chat session. A multivariate analysis was conducted. Results indicate that online chat is indeed a hybrid form that is difficult to delineate from speech and writing. Text-based online chat shows a somewhat similar rate of contraction to speech, which confirms its hybridity.. Lastly, some implications of the study are given in terms of the learning and acquisition of style in general and in online contextual modes.

  • This study analyzed expression types of dot patterns and derived out inherent characteristics to provide fundamental resources for advancement of high value added creative designs. As a result of the study, Firstly, the circular motive was used to form silhouettes or as a symbol of a decoration. Secondly, a simple form and color dot pattern was used to create one side, or a circular shaped accessory was used to be recognized as a construction line or a decoration line. Thirdly, textile printing is mainly used but handicraft and decorative images were used to add vitality through piece technique, embroidery, collage, cut-out, patch work, etc. Fourthly, different circular motives were integrated, partitioned and duplicated for abstract geometrical images. Fifthly, variations were added by mixing different dot patterns that are arranged regularly and irregularly in different sizes and gaps creating compounded designs with handicraft touches, different angles or on top of each other. Sixthly, hybrid images were created with rearrangement of dot patterns and by adding floral shapes, stripes or other abstract and geometrical shapes. Such various and creative attempts construct new formative beauty in fashion design and I believe that it can establish the development of unique images that satisfies the taste of today's consumers.

  • The purpose of this study was to research the limits of sports films from the perspective of social structural on the category, the material, the formulas and the mixture of the materials in the movie. The results were as follows: First, Sports films have been faced with the basic problem as to what a standards the category were classified with because of the conceptual confusion about what sports movie was. Second, sports movies could not catch up with a lot of changes in the movies. Third, sports movies were confined, without flexibility, within old fashioned formality of stories which prevails in modern sports. Lastly, they didn't have the mixture of the materials due to the fixed recognition on sports.
