U-Publication, the Tag-Embedded publication, is one of U-Media. U-Media is defined as a media where human creates and consumes content through not only human cognitive and perceptual processes but also through the interactions between surrounding digital systems. U-Media provides information by generating, collecting, and attaching the content itself and the related information based on the interaction of the bio-systems incorporating digital information and devices embedded in humans, and surrounding objects including external digital devices. Using U-Publication, readers consume its content not only in offline but also online through a mobile RFID reader which touches and connects the URLs embedded in the RFID tags attached to it. Readers can consume the additional content though the hyperlinks attached to U-Publication and perform commercial activity as well as consumer the printed content. This paper defines the RFID-Tagged publication, proposes its related business models, and evaluates the alternative business models through a simulation study.

The study aims to investigate the effects of media and self-image congruity of ideal body image on the dieting and exercising behaviors of Korean and U.S. female college students. This study focuses on the concept of self-image congruity in order to examine how respondents perceive actual and desired self-images compared to an ideal female body image selected by respondents. A self-administered survey was conducted, resulting in 331 total responses (194 from Korean students and 137 from U.S. students). The data were analyzed through descriptive analysis, t-test, exploratory factor analysis, and regression analysis using SPSS 23.0. The findings revealed significant differences between Korean and U.S. female college students. U.S. students were more exposed to body image ideals in the media than Korean students; however, Korean female students valued the information regarding ideal body image conveyed by the media more than U.S. respondents. Among Korean female students, exposure to media messages regarding ideal body image and media importance had significant effects on desired self-image congruity, while these factors were not significant among U.S. students. However, there was a negative effect of media exposure on actual self-image congruity among U.S. respondents only. Additionally, the study uncovered that Korean students manage their body image through dieting behaviors while U.S. respondents manage body image through exercise behaviors (weight training as well as cardiovascular exercise). The study provides further support for self-image congruity, which extends its applications to the body image field.

RFID 태그 부착 출판물(U-Publication)은 U-Media의 하나로 소비자가 기존의 출판물을 오프라인에서만 소비했던 것과는 달리, 복수개의 태그가 부착되어 있어 RFID 리더(reader)로 태그에 저장된 URL을 통해 온라인으로 접속할 수 있는 것을 말한다. U-Media는 사람의 생체시스템뿐만 아니라 사람이 지닌 디지털정보나 디바이스, 그리고 주변 사물과 상호작용을 하여 컨텐트 생성과 동시에 자동으로 관련 정보를 수집, 첨부함으로써, 기존의 미디어가 전달하지 못했던 정보까지 제공하여 준다[1]. U-Publication은 온라인과 오프라인이 Seamless하게 연결되어 양방향으로 정보가 이동할 수 있다는 측면에서 U-Media라고 할 수 있으며, 소비자들은 RFID 태그 부착 출판물의 인쇄된 컨텐트 뿐만 아니라 출판물에 부착된 태그의 링크를 통해서 추가적인 컨테트를 소비할 수 있고 다양한 상거래를 할 수 있다. 이 논문은 RFID 태그 부착 출판물의 정의와 이를 기반으로 한 비즈니스 모델에 대한 분석과 제안을 담고 있다.

This research aims to compare the features and environments for media acceptance of tablet against laptop computer in the u-Learning environment. While it is need to accept suitable media for u-Learning learner, most of existing research has focused on finding factors which can affect perceived usefulness and perceived ease of use on extended technology acceptance model and how to fulfill those factors. Thus this research drew four categories need to use media in the u-Learning environment, then adopts Kano's model and IPA methodology. The results by Kano's model identify exciting and basic attributes which do not match overall satisfaction of learners. Moreover the research analyses by IPA methodology illustrate whether the factors considered important by learners are fulfilled. The research also emphasis the significance of enhancing relative importance as well as satisfaction of the properties for media acceptance in the u-Learning environment.

Today, the Publishing world goes to meet 'U-Publishing' which means the time of 'Ubiquitous Publishing 'in the Latin language. The concept of book evolves into the concept of U-Book beyond the concept of e-book from the concept of paper media book of the past Although the concept of book changes according to the times and media, there are design values which is changing and which isn't changing. We can regard these points of views as the immediate and the ultimate value. The immediate value means the values of the present time which explains the sprit of the time, and the ultimate value means what will not change beyond the time in spite of the difference of media which delivers design. This paper deals with the design of U-book concept which has been appear since 2n5 from the standpoint of the immediate and the ultimate value.

The purpose of this research was to investigate fluidization characteristics of three solid particles, correlations between voidage and superficial velocity. The inside diameter of a column did not affect the fraction void-superficial velocity relationship for fluidization systems which was obtained as follows: $\frac{u}{u_t}={\varepsilon}^{3.703}----Sea\;Sand$ $\frac{u}{u_t}={\varepsilon}^{3.5665}----long\;Exchange$ $\frac{u}{u_t}={\varepsilon}^{4.066}----GAC$ And the sphericial type media is good for fluidized systems as it maintains low voidage. Actually, if biofilm attached to media (bioparticle), the density became lower in fluidized bed biofilm reactor. Therefore, as the density of media become higher, it is easy to maintain fluidized beds.

이 논문은 유비쿼터스 컴퓨팅 환경에서 디스플레이와 디스플레이를 시청하는 개인 단말을 가진 사용자간의 연결 완전성(Seamlessness)을 구현할 수 있는 디스플레이 모델을 제안한다. 기존의 디스플레이가 사람의 시청각에만 호소하는 것과는 달리, U-Display는 디스플레이에 컨텐트를 표시함과 동시에 해당 컨텐트의 링크를 개인 단말을 휴대한 사용자에게 제공함에 따라 디스플레이 및 디스플레이 사용자간의 seamless한 정보 전달이 가능해진다. 논문은 U-Display의 정의와 유비쿼터스 기술을 이용한 디스플레이 비즈니스 모델의 제안 및 분석을 담고 있다.
