We need the customized e-Learning service according to not only developing the wireless mobile and hardware technology, also developing the multimedia process skills. Especially, the beginner who start to learn the first programming course must be provided the personalized learning. The beginner require the repeated practices to obtain the programming skills, also they reveal the different learning effects following the learner capability In this paper. we develop a new e-Learning contents which give the individual service for learner and show the simulation which is program execution to maximize the learning effects.

In this Paper, we introduce an efficient on-line software service using an application customized graphic offloading library. The software service based on graphic offloading provides high-end software, like a 3D graphic design tool, as an on-line software service through using a client graphic rendering. When software is executed on server, its graphic works are handled by a client's GPU, while its data works are handled by a server's CPU. To improve the performance, we apply an asynchronous transmission channel scheme to our developed basic graphic offloading engine. Also, we add optimized common module and application specific module to our engine. To do that, we introduce how to implement the application specific module using analyzing patterns of graphic related APIs and messages that are generated by an executed software process. Also, we propose how to design the optimized common module using server side information caching. Finally, through the performance comparison experiment, we show that improved offloading engine has the better performance than old basic offloading engine.

Recently, Through the linkage and opening, the fusion of the spatial information, it is necessary for productive ecosystem to provide a variety of information and to increase the civil use. Depending on the economic growth, demand for quality of life and well-being has been on the increase. Spatial information service contents for the public convenience has emerged to solve the problem such as health, safety, welfare and discomfort of daily life This study aims to implement search services for a tailored residence space through the three-dimensional data modeling on cadastral information. To achieve this goal, we established the requirements for deriving a registered object by investigating recent trend with respect to existing cadastral data model and defined property and relationship. Focusing on Songpa-gu, Jamsil station in Seoul, we implemented search services for a tailored residence space for three-dimensional right analysis in conjunction with residential and commercial complex building. As a result, we derived a way to supply 3D cadastre information through open platforms (VWorld) and to represent efficiently, which is able to improve the quality of spatial information service contents for the public convenience as well as to widen utilization of information.

뷰티테크시장에서 출시하는 제품 중 영상처리기술을 반영한 다양한 뷰티디바이스가 증가하는 추세이다. 특히 스마트패키징의 경우 주목할 만한 이슈로 뷰티디바이스와 연계된 사용성 및 편리성을 갖춘 애플리케이션 개발이 중요해지고 있으며 사용자가 맞춤형 피부진단 관리 방법에 대한 뷰티정보, 분석리포트, 피부케어샵, 화장품 등을 추천받을 수 있는 뷰티솔루션이 설계되어야 한다. 본 연구는 뷰티케어시장의 전문서비스 영역과 경계를 대중화하여 사용자가 맞춤형 피부진단 관리를 할 수 있는 애플리케이션 설계에 주안점을 둔다. 이를 위해 피부진단 관리 데이터 수집방법의 변수를 정의하고 사용자에게 제안, 모니터링, 뷰티 홈케어 정보, 전문서비스와의 연계방안 등 맞춤형솔루션을 제공할 수 있는 비즈니스플랫폼모델을 제안하고자 한다.

사용자에게 맞춘 개인화된 제품과 서비스를 제공하는 기술의 발전으로 개인화의 수요는 점점 늘어날 것으로 전망하고 있다. 또한 개인 맞춤형으로 전문 스포츠 선수화, 족부 장애우를 위한 정형 제화 등 전문적인 기능 중심의 개인화나 패션을 위한 스타일 중심의 개인화 등 개인 맞춤 제작 신발을 제작할 때 기존의 아날로그적인 방식으로 발 변인을 측정했을 때 각 변인에 대해 기준점이 명확하지 않아서 재현성이 떨어진다. 따라서 본 논문에서는 자를 이용해 간단히 측정 가능한 기본적인 발 변인 이용하여 다른 변인들을 학습하고 딥러닝을 이용해 추정하는 방법에 대해 서술한다. 이를 위해 20개의 발 변인을 휙득 하였고 그 중 6개의 기본적인 발 변인을 이용해 14개 변인을적합 방지를 위해 Dorpout을 적용해 학습하고 학습한 데이터를 이용해 학습하지 않은 데이터를 테스트해 각 변인별 결과를 보여준다.

With the emergence of pervasive computing, personalization becomes an important issue to provide with users customized services, anywhere and anytime in their specific environment. Many researches have shown the possibilities of personalization by acquiring and processing sensor information around users. However, personalization remains still at its infancy, since most researches have failed to consider various contexts comprehensively besides sensor data, and just developed tailored services for a specific application domain. In this work, we propose a simulation-based CAS (context Aware Web Services) development methodology. Our methodology considers various contexts on users (eg. current location), web services (eg. response time), devices (eg. availability) and environment (eg. sensor data) all together by simulating them on the fly for personalized and adaptable services.

In this paper, we present a service model which serves multimedia contents to end consumer(End-user) that have various mobile communication terminals under a communication & broadcasting converged environment that broadcasting and communication networks are linked. A main feature of this service model is that it has a distribution structure that deliver to end consumer via adaptation of content from production of contents offering End to End (E2E) media QoS and personalized contents consumption. The proposed service model may be used as a reference model for distribution of multimedia content in communication & broadcasting converged environment in the future.

Nowadays, as it goes on digitalization of the broadcasting and the convergence of the broadcasting and communications , it has been developed into the ubiquitous individual media consuming pattern which can easily and comfortably consume the favorite contents through any devices at anytime and/or anywhere. For this, in this paper, we propose personalized broadcasting service that can provide a convenient access of the contents that users want to watch at anytime by considering the user preference and consumption characteristics as well as an efficient browsing and watching of the particular program segments more advanced than the data broadcasting services. Moreover, it is implemented the TV-Anytime standard based on personalized broadcasting terminal platform by us. The developed services and terminal will used on broadcasting environment in which many services and the contents. The result of that is the broadcasters/service providers and content providers can provide differential broadcasting services which is suitable to each user such as personalized broadcasting service in near future.
