웹 코스웨어의 대부분은 2 차원적인 텍스트와 이미지를 이용한 것으로 설계되어 있으나 3 차원의 입체개념 형성이 필요한 입체도형 학습에서는 효과적인 학습이 되기 어렵다. 본 논문은 WWW에서 3차원 가상현실을 적용하여 구현한 웹 코스웨어로 중학생을 위한 입체도형 학습을 주제로 하였다. 2 차원 평면공간에서는 설명하기 어려운 입체도형의 성질을 3 차원의 가상현실의 공간에서 학습자 스스로 다양한 경험을 통해 이를 이해하고 학습의 개별화 요구를 충족시키는데 그 목적이 있다. 이를 위해 학습자가 주도적으로 학습을 조작, 진행해 나갈 수 있는 구성주의 학습이론을 기반으로 웹에서 3 차원 가상공간을 제공하는 스크립트 언어인 VRML2.0 을 이용하여 모델링하여 동적인 학습과 상호작용성을 높일 수 있도록 구현하였다.

The purpose of this study is to analyze cases related to the jewelry industry, focusing on the social phenomenon triggered by NFT in the Web 3.0 era, and to find the useful direction in the jewelry industry. For finding the direction, I analyze the concept, definition, and characteristics of NFT. And the three characteristics, transparency and eternity and uniqueness are embedded in the strategies of the situation analyzed through the study. As a result of the study, It is important to analyze of the MZ generations, which is the main consumer group of NFT and to possess the digital agility needed in the Web 3.0 era. Through in the convergence researching between Metaverse and NFT in the future, I hope to contribute to strengthen the competitiveness of jewelry brand.

Demands for a system which enable users to retrieve any kind of geographic and regional information over the Web have been increasing. However, in order to obtain geographic or regional information over the web, users still need to search web pages related to region by inputting keywords and to arrange the searched results with map. We can solve that problem by using the fact that most of geographic and regional information contain geographic keywords related to location. In this paper, we propose a system to retrieve geographic and regional information efficiently. For the purpose, we present a conceptual model based on three layers of "Real-World", "Knowledge", and "Applications", from the web space and construct the above link process. These layers are connected to each other and enable users to navigation information over the linkage. Especially, users can obtain various correlated information about geographic information and properties.

One of the most popular technologies in Web2.0 is tagging, and it widely applies to Web content as well as multimedia data such as image and video. Web users have expected that tags by themselves would be reused in information search and maximize the search efficiency, but wrong tag by irresponsible Web users really has brought forth a incorrect search results. In past papers, we have gathered various information resources and tags scattered in Web, mapped one tag onto other tags, and clustered these tags according to the corelation between them. A 3-tag based search algorithm which use the clustered tags of past papers, is proposed in this paper. For performance evaluation of the proposed algorithm, our algorithm is compared with image search result of Flickr, typical tag based site, and is evaluated in accuracy and recall factor.

As the development of IT technology and Web services have changed recently, education environment combined with high-tech digital content is becoming a new trend with the demands of educational consumers. In Korea, however, there is no systematic discussion on the issue, and there is not enough evidence to verify the effectiveness of the research. Therefore, we will systematically analyze the educational effects of Digital Storytelling to create an educational environment that meets the new horizon of intelligent web and personalized service provision in the Web3.0 era, In this study, 12 domestic experimental studies that verify the educational effects of digital storytelling were systematically analyzed, compared with overseas cases, and proposed development plans in the Web3.0 era.

Web accessibility refers to the practice of providing equal access to web sites to people without and with disability. This study aims to investigate the web content accessibility of 153 university libraries in Korea, and further suggest the approach to implement an effective university library web site to meet Korean Web Content Accessibility Guidelines(KWCAG). Survey was conducted with two steps. The first step was to find out the general level of web accessibility of all university library web sites using an automatic appraisal tool, KADO-WAH2.0, and the detailed examination of web accessibility check items was limited to 19 web sites which proved excellent in automatic appraisal. Regretfully, the result says that there is no perfect web site. Therefore every university library is advisable to make good use of the findings to meet all the requirements of KWCAG. In particular, the basic requirements, such as voice service, resizing and highlighting text, must be fulfilled by priority and to almost all contents.
