We studied the variety and affinity between the successive words in the text document A number of groups were defined by the frequency of a following word in the whole text (corpus). In the previous studies, the Zipf's power law was explained by Chinese restaurant process and hub node was searched after by examining the edge number profile in scale free network. We have observed both a power law and a hub profile at the same time by studying the conditional frequency and degeneracy of a group. A symmetry between the affinity and the variety between words were found during the data analysis. And this phenomenon can be explained within a viewpoint of "exploitation and exploration." We also remark on a small symmetry breaking phenomenon in TIPSTER data.

The flower arrangement that human beings interact with the natural plants have characteristics according to their historical background and ethnicity and different aspects of culture related of the flower arrangements have been created by human inspiration and formative ability. The Korean flower arrangement is a product of civilization which originated in the natural environment of the four seasons. As background with the natural unity ideology, the Korean Flower Arrangement makes the life and philosophy of the naturalistic nature that flows in the mind of our nation to the relaxing beauty suited on cultures of ages by the Virtue, the Will, and the Vitality. The Literary Flower Arrangement is, based on the higher human personality and poetic sentiments as ideologies of our traditional oriental philosophy, the formative art made for aesthetic implications of philosophy by consisting plants' characters and tastes without expression of technical skills. In this study, focused on pine tree, in order to clarify that the flower arrangement of our spiritual culture is the Literary Flower Arrangement, make Identifying aesthetic characteristics through, the backgrounds and sources of being expressed by the Literary Flower Arrangement, poetic feelings, symbolism, metaphor, the formative form of flower arrangement, decoding of the flower arrangement genes, and the same time deduce the record of literary work and classify it each era, and establish the Literary Flower Arrangement theory which is the essence of Korean flower arrangement.

The purpose of this study is to present the mental model of young adolescents' media environment and the use and to provide several educational suggestions drawing on the revealed model. For this, the data were collected through 4 activities such as interview, picture drawings, word association experiment, and sentence completion task with ten 4-5th graders in elementary schools; they were qualitatively analyzed by 2 researchers. First, the meaning components driven by sentence completion task, word association experiment were totally 6 components: media device, connection(alienation), competence(provision), entertainment, adverse effects, ambilaterality. Second, the components of media mental model driven by pictures were 4 components: functions/competence, entertainment, conflict with paper books/sharing, harmfulness/ambilaterality. Third, the components from interview consisted of conflict between paper books and electronic media, communication-centeredness, fear(addiction) and users' qualification. Based on those results, careful examination in cyber talk, necessity of addiction prevention, active development of learning media and their balanced utilization with books, and healthful media literacy education and reinforcement of critical thinking were suggested.

This paper research an answer to the question what is the relation between intrinsic value of truth and substantiality of truth. The concept of substantiality can be variably defined, but I characterize it as being an opaque concept. Michael P. Lynch, who is one of the most influential pluralists about truth, accept both that truth is substantial and that truth is intrinsically valuable. This paper analyzes Lynch's argument for the intrinsic value of truth, and will show that his argument is independent of his theory which insists that truth is manifested plurally. Moreover I will discuss how Paul Horwich who is a deflationist denying substantiality of truth explains the intrinsic value of truth. And comparing these two views, I will elaborate the reason why intrinsic value of truth and its substantiality are logically independent each other. Finally, I will suggest a brief case which shows an implication included in the conclusion that plural manifestation of truth does not generally entails plurality of value of truth.

The purpose of this study is to analyze the shipbuilding structure of field tangerine by ten days and by month. By estimating and analyzing the price flexibility function of field tangerines, this study determines whether the shipment control can stabilize and increase the income of field tangerine farmers and provides policy implication. Considering the overall market, a 1% increase in shipment volume indicates that the coefficient of price flexibility varies with ten days and month. The greatest decline is from late October to early January. Therefore, a greater necessity of shipment control is required during late October and early January. The coefficient of the dummy variable (DUM_Q) indicates the year in which the quality declines is statistically significant and sign. The coefficient of the dummy variable (DUM02) represents the year in which more than 7 days after the New Year holidays are in February is statistically significant and sign from early October to late January. Therefore, it can be seen that the necessity of shipment control is more required when New Year holidays are in February. The greatest decline in the coefficient of price flexibility is from October to December. Therefore, a greater necessity of shipment control is required during October and December. The signs of coefficients of DUM01 and DUM_Q dummy variable of the price flexibility function suggest that the need for shipment control is more important when quality is worse than better quality and that the necessity of shipment control is more required when New Year holidays are in February, respectively.

People are most commonly divided by their nationality, but that does not mean they share the same culture. Even for people from one cultural background, subcultures play an important role for diversity and identity, and popular music is one way to express them. This study analyzed 6 songs of the Hip Hop genre from the US, Germany and South Korea, with one song each from the time of first emergence of the term 'Hip Hop' and one song each from 2016, selected on the basis of popularity indicated by music record sales and specialist literature on the history of Hip Hop. Through semiotic analysis of early and recent Hip Hop in each country, the changes in popular Hip Hop over time were examined. The results of this study show that through standardization, Hip Hop in the three countries has superficially become more similar and more focused on the individual, but on a detailed level shows significant differences: while U.S. Hip Hop refers to the American Dream, German Hip Hop displays an extreme image of masculinity, and Korean Hip Hop deals with private thoughts. Although popular Hip Hop nowadays does not explicitly exercise social criticism it is still ascribed the symbolic significance of a rebellious and revolutionary cultural practice that can be used to criticize and change culture as well as society.

3GPP proposed f8 and f9 algorithms based on the block cipher KASUMI to provide the data confidentiality and integrity over a radio access link for IMT-2000(W-CDMA). Also 3GPP proposed Milenage algorithm based on the block cipher Rijndael to provide an example set for 3GPP authentication and key generation functions. In order to analyze the security of 3GPP algorithms, we must go ahead an analysis of security of KASUMI and Rijndael. Since S-box is an important point of security of block cipher, in this paper we analyze the S-boxes of KASUMI and Rijndael and compare the S-boxes of KASUMI with the S-box of Rijndael. Although KASUMI S9-box is bad for AC and SAC, we find that AC of KASUMI FI function containing S7-box and S9-box is equal to AC of Rijndael S-box and SAC of KASUMI FI function is better than SAC of Rijndael S-box.

In this study, two alternative models are developed and tested in order to investigate the relationship between retailer image and its private brand attitude. The halo effect model hypothesizes that retailer image is related as a halo in private brand evaluation and the summary construct model hypothesizes that retailer image functions as a summary construct of private brand evaluation. The results indicate there are moderating effects of 1) familiarity with a private brand and 2) the characteristics of a product category High familiarity is related with the summary construct model and low familiarity the halo effect model. In private brand food, the summary construct model fits better and explains more adequately that private brand evaluation influences retailer image as a summary construct. In private brand clothes, however, the halo effect model performs better in explaining the relationship between retailer image and private brand attitude.
