유비쿼터스 시대의 도래에 발맞춰 유저가 콘텐츠를 이용하는 방법과 사용하는 기기는 PC에 머물지 않고 점차 다양화, 소형화 되고 있다. 최근, 많은 콘텐츠 중에서 e러닝 콘텐츠에 대한 관심은 높아지고 있으며, 본 논문에서는 e러닝 콘텐츠를 다양한 디바이스에 적합한 콘텐츠로 동적 변환하는 모듈을 제안한다. CC/PP 기반의 디바이스 프로파일과 사용자 정보를 포함한 유저 프로파일, 콘텐츠 구성정보를 가진 콘텐츠 프로파일을 통합하여 특성을 추상화 한다. 추상화 된 프로파일을 기반으로 변환방법을 생성하여 콘텐츠에 적용함으로서 해당 디바이스에 적합한 콘텐츠로 적응화 한다. 기존 HTML의 경우 잘 구성된(Well-formed)문서가 아닌 경우가 많고, 문서 내에 데이터와 구조정보를 모두 포함하고 있으므로, 요구되는 데이터의 추출과 정형화된 변환룰의 적용에 어려움이 따른다. 그 대안으로 본 적응화 모듈은 문서의 데이터와 표현 구조를 분리 할 수 있는 XML/XSL 기반의 콘텐츠를 대상으로 하고 있으며, e러닝 콘텐츠의 특성에 적합한 콘텐츠 프리패치 및 캐시 기법을 적용하여 콘텐츠 동적변환에 따른 응답시간 오버헤드를 최소화 하였다.

Developments and changes in digital environment based on computer technologies and internet networks enabled us interactive communication for planning and execution through the freedom of 'connection', 'sharing', and 'conversion'. The subject of this study, interactive commercial, might be the core of success based on creation which stems from communication design, revolution in design and technology, and conversion. Communication in modern economy is not optional, but essential. Furthermore, like evolution process up to Augmented Reality from developments of mobile communication technology, or concept in paradigm change, digital interactive commercial means the core of success, not a part of it. Therefore, in order to achieve success in the global competition structure, mobile communication design, revolution, and creation which produce added value shall be working as a base. In order to reach effective communication process performance of interactive commercial media, this study would like to propose building a media commercial system which is realized by human senses. Using this, standardized methods for interactive commercial which can be used together with augmented reality based on digital technology, and for using digital robot contents are available, along with methodology system of their use. In addition, the ultimate goal of this study aims to discover new factors through reorganization of precedent analysis and adaptation based on academic achievement and practical application. And thus, it wants to contribute to practical use of interactive commercial out of augmented reality-based communication in which technology, marketing, and design are integrated to be used in real sense.

This study was conducted to evaluate the chemical composition, digestibility, and energy value of 15 non-conventional feeds produced in South Korea as ruminant feeds. Three Hanwoo steers (body weight, $520{\pm}20.20kg$) fitted with a permanent rumen cannula and duodenal cannula were housed individually in tie-stall barns, followed by a 14-day adaptation period and 3-day experimental period. Chemical composition analysis, in situ nylon bag, and mobile bag technique were used as experiments. As a result of the chemical composition analysis offeeds, crude protein (CP) contentsofmalt meal, perilla meal, soy sauce cake, and soymilk residue were greater than 30%. As a result of the degradability characteristics analysis of feeds using an in situ nylon bag, rumen undegraded protein (RUP) contents of beet pulp, brewer's grain, coffee meal, malt meal, milo bran, perilla meal, ramen residue, and soymilk residue were greater than 50%. Analysis of total digestible nutrient (TDN) values of feeds using an in situ mobile bag showed that TDN values of beet pulp, brewer's grain, makgeolli residue, milo bran, perilla meal, ramen residue, rice bran, soy sauce cake, soybean curd cake, soymilk residue, and wheat bran weregreater than 50%. In summary, these non-conventional feeds have high potential value as good feed resources to replace formulated feeds or roughage. Therefore, the chemical composition, digestibility, and energy value of non-conventional feeds obtained from this study can be used as base data for the manufacture of ruminant total mixed ration (TMR) with improved feed efficiency, reduced feed costs, and reduction of environmental pollution.
