  • This paper proposes a virtual relevant document technique in the teaming phase for text categorization. The method uses a simple transformation of relevant documents, i.e. making virtual documents by combining document pairs in the training set. The virtual document produced by this method has the enriched term vector space, with greater weights for the terms that co-occur in two relevant documents. The experimental results showed a significant improvement over the baseline, which proves the usefulness of the proposed method: 71% improvement on TREC-11 filtering test collection and 11% improvement on Routers-21578 test set for the topics with less than 100 relevant documents in the micro average F1. The result analysis indicates that the addition of virtual relevant documents contributes to the steady improvement of the performance.

  • In this study, discourse patterns of four peer small groups in learning science concepts were examined. Verbal interactions during small group discussions were audio- and video-taped, transcribed, and analyzed. Three coding frameworks for the levels of turns, interaction units, and episodes were developed. In the analyses of turns, no clear relationships between students' prior achievements and contributions to knowledge building processes were found. Partly participating modes and symmetrical interaction modes were dominant in the analyses of interaction units to suggest that some students did not participate actively in small group discussions and that students' verbal interactions were superficial. The analyses of episodes also indicated that agreeing and/or partial elaborating on group members' ideas were the most frequent patterns and dialectical exchanges were rare in small group discussion.

  • Two government affiliated research institutes, EDUMAC and AURI, are developing some tools for an user participating design process in public recently. The tools are originated from DQI/DQIfS, launched in 2002 by CIC(Construction Industry Council) in U.K.. At the beginning DQI/DQIfS was not a tool for making a decision but for a communication between layman and experts of architectural process. Because of this intent the most crucial thing is not DQI/DQIfS itself but how to use the tool: CIC is trying to develop various ways of facilitation. Domestic situation is no exception. Without a proper tool there were an independent user participating process in 2001 and it must have been the first participating process in architectural discourse. Through the seven workshops, the users of Namhansan elementary school drew not only the vision of the school but also concrete requirements which have been continuously adopted so far. The aims of this paper to analyse two facilitation processes: DQI/DQIfS in U.K. and the case of Namhansan process. Even not a proper tools for the process there was a spontaneous facilitation in Namhansan process. When we make a comparison between the Namhansan process and the DQI/DQIfS process there are considerable similarities in terms not only of the process itself but also the results. It shows that there are possibilities to make a Korean facilitation in a user participating process and this study must be the first step.

  • This study, by analyzing two recent television dramas, attempts to identify the ways how popular cultural texts deal with supernatural beings and to discuss political meanings of the ways in the context of neoliberal Korea. The results are: (1) The narratives make a clear line between the supernatural and the ordinary. (2) The supernatural is effectively used in the narratives to extend the boundary of conflict structure towards structural social problems that the society is now facing. (3) When the text resolving the conflicts, the supernatural is also critical, which makes the whle narrative in line with fantasy rather than reality. These results suggest that the conclusion of the previous studies, arguing the use of the supernatural by popular cultural texts tends to function as a form of resistance against neoliberal discourse structure, needs to be negotiated. It is also reaffirmed that we need to explain political meanings of popular cultural texts dealing with supernatural beings, with its double-sided and ambivalent effects.

  • The purpose of this research is to investigate how an elementary English class is presented in terms of communicative properties using COLT and TALOS because previous studies mainly used COLT. A lack of TALOS has shown on the previous studies. Also, this study takes a close look into whether the English class is communicative or not communicative since previous studies criticized in that elementary English classes are not communicative. For the purposes of this research, COLT part B and TALOS low-inference were used to analyze one elementary English class which had won the grand prize at English class contest. The result of this study revealed that the class is communicative in terms of high quantity and quality of students utterances, high ratio of students' discourse initiation, students' unpredictable information giving utterances and extension of utterances. Findings from this study revealed the good elementary English class characteristics of this class: students' participation, focus on affective atmosphere, students-directed activities, and unconscious internalization of target expressions through repetition.

  • Fur is conceived as a material signifier, not only with its commodity value as luxury goods but also as its symbolic value as objects invested by one's libidinal desire. In this study, complex meanings of fur as multi-layered signs of political and sexual power focusing on fetishism shall be explored, especially on the spectacle fetishism acted by mass media during the anti-fur movement in the 1980s. In conjuction herewith, a highlight shall also be made to the symbolic value in fashion design since 1990s. In this study, first, as a theoretical investigation, fetishism, that has been traditionally considered only as sexual fetishism in fashion discourse will be explored in socio-economic level. Second, in historical context, how the meanings and values of fur have become realized in various cultural spaces, such as literature, art, film and finally, fashion will be viewed. In fashion, fur is a product of desire and power influenced by commodity fetishism as well as sexual fetishism. During the anti-fur movement, mass media has developed the concept of spectacle fetishism. Fur is a sign of animal-victim, and fur-clad women is viewed with images full of imperialsm, sexism and racism, thus act as derisive spectacles of consumerism. Since 1990s as a reflection on anti-fur movement, fetishistic characteristics, which challenge traditional operation method, are expressed by disguise, parody, and returning to the nature. First, fur as disguise is intended to hide sexually perverse, decadent characteristics and expensiveness of fur by texturing or patterning techniques. Second, fur as parody uses fake fur or dyed fur in order to satirize erotically and ethnographically fetishized meanings of fur. Third, aboriginal design of fur is adapted to use symbolic values outside the West, which can potentially mobilize antagonistic oppositions out of their fetishistic regimes. In conclusion, fur as sign of female sexuality and its libidinal profits of exchange, has significant symbolic values expressed in fashion.

  • This paper has tried to analyze the characteristics of space in Korean traditional architecture by deconstructive concept through connecting Lao-tzu's theory, the main discourse of East and West, with Derrida's deconstructionism theory. Derrida's philosophical term of differance(diff$\acute{e}$rance) is similar to Tao of Lao-tzu. It is because Derrida emphasized the relationships with others by trying the strategy of overcoming dichotomous thinking by this term. Tao of Lao-tzu also has the relative characteristics that cannot be concluded by one sole meaning. Like this, Derrida and Lao-tzu are against traditional and dichotomous way of thinking. In this point of view, this study has set Derrida's deconstruction theory and Lao-tzu's thinking as the common viewpoint of this world. And through the phrase of Tao Te Ching which means deconstructive Tao, deconstructive space design vocabulary was derived as mixed no-boundary, shape of no-shape, transcendence of time and space. The deconstructive characteristics of traditional space by case study analysis of Lao-tzu's deconstructive space design are as follows: First, it is not a specific or detailed shape but an unlimited possibility that can be transformed into something else, moving and changing endlessly and has a borderless beauty. Second, it is nothing itself but creates various shapes, as if it exists without shape. Third, it is a relative and unlimited space and pursuits a free form as a non-conceptional shape without any system or value.

  • This study is to examine relationships of several socioeconomic position indicators with mortality risk in a nationwide longitudinal study of South Korea. The Korea Labor & Income Panel Study, conducted on a probability sample of urban South Korean households by Korea Labor Institute, contains date of death information for the decedents which were used to estimate relative risks of mortality and their $95\%$ confidence intervals (CI) with Cox regression analysis. A total of 125 men and women among 8,415 subjects died between 1998 and 2002. Socioeconomic differentials in mortality were observed after adjustment for sex and age. Those with less than 12-year education had 1.90 times $(95\%\;CI=1.25-2.91)$ greater mortality risk than those with 12-year education or more. Greater mortality risks were also found among those with low occupational class and manual occupation. The magnitude of differentials in mortality risks between occupational class were similar in two different approaches to measuring women's occupational class: (1) approach 1 where women, married or not, retain their own occupational class, and (2) approach 2 where married women are assigned their husbands' occupational class. Relative risks of dying among those with low household Income were 1.62 $(95\%\; CI=1.08-2.42)$ compared with the counterparts. Those who reported economic hardship at the time of survey in 1998 had greater risk of mortality $(RR=1.83,\;95\%\;CI=1.21-2.78)$ than those who did not. In conclusion, increased social discourse and policy discussions about these health inequalities are needed in Korean society. Future studies should explore the causes and mechanisms of socioeconomic mortality inequalities.

  • The aim of this study was to analyze cohesion and word information among different types of questions in the English reading section of the College Scholastic Ability Tests (CSAT). The types of questions were divided into three categories: macro reading, micro reading, and indirect writing. Reading texts from 1994 to 2017 CSAT were analyzed by Coh-Metrix, an automated evaluation program of text and discourse. The findings of this study indicated that there were statistical differences among the three categories of questions for noun overlap, stem overlap, adversative and contrastive connective, additive connective, pronoun incidence, age of acquisition, concreteness for content word, imagability, and meaningfulness. The information of the findings bore pedagogic implications for developing textbooks, questions for CSAT, and reading strategies by students.

  • This study starts from the awareness that 'rebellious communication' is still being regulated in various ways even though 'rebellious communication' was declared unconstitutional in a decision by the Constitutional Court in 2002. The meaning of 'rebellious' has been amplified and transformed at various points through the censorship systems established during the Japanese colonial era, the US military period, and the regime of Park Jung-hee. In particular, 'rebellious communication' is regulated to protect 'national security' and 'social customs' from the perspective of power. This study analyzed discourses containing judgement about the Park Jung-geun case and the violation of the National Security Law using retweet accounts or posts related to North Korea. This study explores the genealogy of 'rebellious communication' based on its relationship to the characteristics of Twitter and specific individuals.
