This paper presents the concepts of ubiquitous computing technology to construct a ubiquitous learning environment that enables learning to take place anywhere at any time. This ubiquitous learning environment is described as an environment that supports students' learning using digital media in geographically distributed environments. The u-learning model is a web-based e-learning system that could enable learners to acquire knowledge and skills through interaction between them and the ubiquitous learning environment. Students are allowed to be in an environment of their interest. The communication between devices and the embedded computers in the environment allows learner to learn while they are moving, hence, attaching them to their learning environment.

Most measuring devices are equipped with RS232 interface or GPIB interface for communicating with computers. If the measuring devices can be accessed by a server computer, the valuable information from the devices can be effectively shared with other computer via internet. VRML is a web based technology for specifying and delivering three-dimensional interactive visualizations over the internet through a web browser. This paper proposes a remote 3-dimensional monitoring system for digital multimeter equipped with RS232 interface by utilizing VRML.

본 논문에서는 웹 페이지에서 사용되는 광고 콘텐츠에 대해서 나타낸다. 웹 페이지에서 사용되는 광고 콘텐츠는 모션 그래픽으로 제작하여 인터렉티브하게 이용 된다. 또한 웹 페이지에서 사용되는 광고는 광고의 특성을 가지고 있다. 따라서 광고의 특성에 따라 콘텐츠의 특성도 달라진다. 웹 페이지에서 사용되는 광고 콘텐츠은 특성에 따라 이미지 광고와 동영상 광고로 분류한다. 이들 콘텐츠의 특성으로 이미지의 사이즈와 동영상의 사이즈, 제작 파일 크기, 재생 시간, 웹 페이지의 위치에 따라서 다양한 광고 효과를 연출한다. 따라서 광고 효과를 나타내기 위해서는 제작 광고 콘텐츠의 특성과 인터렉티브 콘텐츠의 특성이 고려되어야 한다.

This paper presents a virtual laboratory system which can be creating efficiencies in the learning process. The proposed virtual laboratory system for electrical circuits provides interactive learning environment under which the multimedia capabilities of world-wide web can be enhanced. The virtual laboratory system is implemented to describe the on-campus laboratory, the learners can obtain similar experimental data through it. The virtual laboratory system is composed of four important components : Principle classroom, Simulation classroom, Virtual experiment classroom and Management system. Learning efficiencies as well as faculty productivity are increased in this innovative teaching and learning environment.

본 논문에서 제안한 MPEG-4 기반 대화형 MOD 서버 시스템은 데이터 공유 네트워크(DSN)를 이용한 클러스터링 서버 구조를 채택하여 클러스터링과 가상서버시스템, 데이터 공유 네트워크 기법을 적용한 복합적 구조를 가진 서버시스템을 설계 구현하였다. 본 논문이 제안한 서버 시스템은 확장이 용이하고, 각 서버 노드가 이상이 발생할 경우 타 서버에 영향을 주지 않는 독립성이 확보돼 안정성이 향상되었다. 그러나 DSN 에서 사용되는 NFS나 Samba 등은 보안에 취약하며, 네트워크 전송에 따른 오버헤드의 보완이 필요하다.

Objectives: Screening for colorectal cancer is considered cost effective, but is underutilized in the U.S. Information on the efficiency of "tailored interventions" to promote colorectal cancer screening in primary care settings is limited. The paper reports the results of a cost effectiveness analysis that compared a survey-only control group to a Centers for Disease Control (CDC) web-based intervention (screen for life) and to a tailored interactive computer-based intervention. Methods: A randomized controlled trial of people 50 and over, was conducted to test the interventions. The sample was 1224 partcipants 50-70 years of age, recruited from Kelsey-Seybold Clinic, a large multi-specialty clinic in Houston, Texas. Screening status was obtained by medical chart review after a 12-month follow-up period. An "intention to treat" analysis and micro costing from the patient and provider perspectives were used to estimate the costs and effects. Analysis of statistical uncertainty was conducted using nonparametric bootstrapping. Results: The estimated cost of implementing the web-based intervention was $40 per person and the cost of the tailored intervention was $45 per person. The additional cost per person screened for the web-based intervention compared to no intervention was $2602 and the tailored intervention was no more effective than the web-based strategy. Conclusions: The tailored intervention was less cost-effective than the web-based intervention for colorectal cancer screening promotion. The web-based intervention was less cost-effective than previous studies of in-reach colorectal cancer screening promotion. Researchers need to continue developing and evaluating the effectiveness and costeffectiveness of interventions to increase colorectal cancer screening.

Recently, the Web 2.0 bas gained much attention as an advanced form of Web technology. It is well observed that openness, participation, and sharing are the key ideas of Web 2.0 among many desirable characteristics of the technology. Furthermore, Wiki is one of the best representing tools that reflect effectively most of the characteristics of Web 2.0. Wiki is widely used to provide a Web-based communication tool for collaborative writing and editing freely. Therefore, it may be used for collaborative learning so that students can learn how to interact online with each other effectively and also acquire communication skills in an affirmative way. In the paper, we will discuss how students can change their aggresive, offensive, judgemental attitudes to affirmative, aggreable, thoughtful ones by way of exposing them to collaborative learning environment using Wiki as their interactive communication tool.

In this paper, we propose an educational content which can be applied to the web interactivity. Rapidly growing digital media has been applied to various fields and made people experience multiple media. The development of digital media also influenced education. As a result, the environment of computer-based education was produced based on CD-ROM titles, video, and the web. Active communication with students is impossible using traditional educational methods. However, the students' motive for learning can be enhanced through the digital media. In this paper, we apply concrete poetry which is simple, brief, and focused on visualization to the web environment. It has made people easily and interactively access the web to learn better through participation. We also applied concrete poetry to the web based educational games for self-motivated learning.

The prior data structure coursewares have been limited to using a simple screen structure with text, pictures or plain animation so that they have been failed to promote favorable interaction between learners and instructors, and unnecessarily charges the screen. In order to overcome these problems, this paper provides an applet-based simulation environment which enables learner to operate and control the data structure operation with their own data, therefore, the learners can actively and positively participate in a study with this courseware. The instructors can easily deliver the education contents to the learners by using web simulation suitable for IT education media. Also, the courseware can offer a class feedback and required data for students estimation by recording a log.

In accordance with an active development, we now enjoy web 2.0 generation centering bilateral participation through the web 1.0 environment mainly providing the offering information and take a step web 3.0 understanding information by itself. The same time of digital technic development, consumption market arrived at market3.0 generation, also passed by market 1.0 and went via market 2.0 based on bilateral participation and understanding. This change have the marketing implement index changed as well. Nowadays, 7C is generalized of making up sensibility, emotion, communication, relationship, customization and interactive built as a major strategy from the day of 3p focused on customer environment, service process and 4P focused on physical quality of product. It isn't that brand and merchandise create life and experience like as past. It is focused on embodiment of a way of life, culture and creative experience from consumers' own. This treatise, therefore, fixes the object as flagship store positively reflecting the change and examine the change of a marketing code element and social factor stimulating customer behavior change. As a condition of this study, It fixes Maslow Motivation Theory as the main index of customer behavior, and 7C as the marketing code. This treatise ultimately studies the index of flagship store discussion based on domestic outdoor brand cases.
