소수점 아래 0에서 9까지의 임의의 숫자가 무한히 나열되는 무한소수는 '소수점 아래끝자리까지의 모든 숫자를 명확하게 알 수 없는 모호한 수'라는 불투명성을 가지고 있다. 이 논문에서는 이와 같은 불투명성을 야기하는 무한소수 기호로부터 어떻게 연속적인 수를 창조할 수 있었는지를 분석하였다. 무한소수 기호의 완비성 공리에 대한 투명성에 의존하여, 실수 개념이 엄밀하게 형식화되기 이전에도 수학자들은 실수 개념을 다룰 수 있었다. 이 논문의 수학적 역사적 분석은 무한소수에 의존하여 실수 개념을 전개하는 학교수학의 접근과, 완비순서체로서의 실수의 형식적 정의를 다루는 대학수학의 접근 사이에서 야기될 수 있는 이중단절의 문제를 극복하는 데 도움이 될 수 있을 것이다.

The purpose of this study is to analyze modern fashion culture in the 20th century through changes in transmedia in order to better understand characteristics of fashion contents. The study also strived to identify the characteristics of remediation in modern fashion and media by exploring the cultural code, and use it to establish an integrated view. The subjects and the method of the study are as follows. First, the study analyzed the development of transmedia and fashion culture since the 20th century. Second, it identified the transitional characteristics of transmedia. Third, the study analyzed the characteristics of remediation in modern fashion culture by using the characteristics of mediation, which appeared with the transitional characteristics of transmedia. The study results are as follows. First, the types of remediation are 'borrowing,' 'Representation,' 'Expansion,' 'Refashion,' and 'Absorb.' In old and new media, each type can be aesthetically experienced in 'transparency,' opaqueness,' 'Hypermediacy,' and 'Immediacy.' Second, fashion culture can undergo a transformation from its original form to a second and a third iteration, and this process allows for possibility of an expansion of multiple plots and well-rounded character settings. This opens up the possibility for fashion consumer participation, and signifies a transition into an environment where expansion of time and space is possible. The third finding is the non-mediation of fashion objects. The mediating relationship between clothes and media is directly connected to the development of new media. The immersion of new media by fashion consumers has the characteristics of 'transparency'/'Non-mediation,' and the reinterpretation and reproduction of original fashion styles have the characteristics of 'opaqueness'/'Hyper-mediation.' Fourth, fashion culture has data variability. Through 'Borrowing,' 'Representation,' 'Expansion,' 'Remodeling,' and 'Absorption,' the cultural hierarchy of reproduced fashion forms a multi-layered integrated network. Mediation code, which repurposes fashion culture contents, also creates new media fashion through transmedia.

This study aimed to identify target lexical bundles (e.g., on the other hand, at the same time) for argumentative essay writing and rank them in order of teaching priority for Japanese learners. Despite significant functional roles of lexical bundles in academic writing, the inclusion of lexical bundles in argumentative writing had been underexplored. Since argumentative writing skills help undergraduate students prepare for their academic careers (e.g., writing papers), the lexical bundles under this genre deserve more attention. This study first extracted 78 target bundles from L1 argumentative essay corpora (International Corpus Network of Asian Learners of English: ICNALE and Louvain Corpus of Native English Essays: LOCNESS). The study then classified the bundles according to their discourse functions and semantic transparency to estimate the learnability for Japanese learners in L2 compatible corpora with the ICNALE. The results showed that learners had difficulty using the bundles with referential functions (e.g., in the form of) and semantic opaqueness (e.g., when it comes to), suggesting that the bundles in these two categories should be prioritized among the 78 bundles.

Soy protein isolate (SPI)-based nanocomposite films with three different types of nanoclays, such as Cloisite $Na^+$, Cloisite 20A, and Cloisite 30B, were prepared using a solution casting method, and their optical, tensile, and water vapor barrier properties were determined to investigate the effect of nano-clay type on film properties. Among the tested nanoclays, Cloisite $Na^+$, a hydrophilic montmorillonite (MMT), exhibited the highest transparency with least opaqueness, the highest tensile strength, and the highest water vapor barrier properties, indicating Cloisite $Na^+$ is the most compatible with SPI polymer matrix to form nanocomposite films. The film properties of SPI/Cloisite $Na^+$ nanocomposite films were strongly dependent on the concentration of the clay. Film properties such as optical, tensile, and water vapor barrier properties improved significantly (p<0.05) as the concentration of clay increased. However, the effectiveness of addition of the clay reduced above a certain level (i.e., 5wt%), indicating that there is an optimum amount of clay addition to exploit the full advantage of nanocmposite films.

참여, 개방, 공유의 이념을 바탕으로 웹을 플랫폼으로 하여 이용자들이 다양한 콘텐츠를 생산 유통 소비하는 웹2.0 시대에 들어서면서 UCC(User Created Content)가 주목받고 있다. 특히 UCC를 둘러싼 대부분의 논의가 UCC의 활용을 통한 수익창출에 집중되면서, UCC는 뉴미디어환경에 적합한 새로운 '정보상품'으로 인식되고 있다. 그러나 UCC는 정보상품으로서 뿐 아니라 '미디어 현상'으로 이해되어져야 한다. UCC는 미디어 계보학의 관점에서, 볼터와 그루신이 제안한 '재매개'의 논리를 바탕으로 미디어를 향한 투명성과 불투명성의 욕망에 기초해 두 가지 유형으로 나뉠 수 있다. 본 연구는 IPTV, DMB등 다양한 뉴미디어들이 등장하고 있는 컨버전스 시대, 기술 산업 문화를 아우르는 컨버전스 패러다임 안에서 재매개의 다양한 양상을 바탕으로 UCC의 활용방안을 모색한다.
