Recently, there are requires for auction system by growing up internet. This paper says if the customers add wonted goods to wanted list, the system automatically announce information to the customer via Inter Web browsing, whenever the proper goods to register to the auction system by seller. The system provides registration customer information, registration goods, wanted goods. And the application program can be downloaded from the Web System. Especially, this paper provides us very convenience check up service using the mobile phone, we can check our wanted goods or auction lists without regarding to place or time, we can alse purchase the goods more rapidly and easily.

The access to web applications has continuously evolved toward the adoption of content centric interfaces. Services and information items are much of user's concern than web sites. For an efficient accommodation of increasing needs of content oriented operations, the scope of domain names is extended in two directions. A naming scheme is derived that is suitable for resource level access units and the semantics of domain names is conceived as very flexible functions. First extension regards the removal of unnecessary TLD's of domain names for resource level binding. Second extension makes the resource level domain names rich in functional binding and consequently various applications can be directly triggered by the invocation of domain names without intervening medium. These extensions may lay a certain direction for the future internet evolution.

With the increasing of users' request about internet web service, importance of Internet datawarehouse to support decision making of users is increasing now. Early Internet datawarehouse was studied in the form of using existent database and XML. However, because of limitation of information expression ability, it is gradually changed to system that use metadata schema like RDFS. Because of distributed environment of the Internet, integration and saving of each metadata schemas into one global schema is important. However, between each different schema, semantic and structural conflicts can be happen in such situation and they must be controlled. In this paper, we analyze occasions of conflict when integrate distributed metadata schemas and propose conflict resolution technique for efficient internet datawarehouse query processing.

This study aimed to propose a method for collecting and applying media platform based materials at the National Library of Korea. Firstly, we analyzed the current status and limitations of data collection based on domestic media platforms, including the National Library of Korea. Secondly, a literature review method was used to investigate the current status and types of digital content based on media platforms. Thirdly, we identified the types of materials based on media platforms that are not currently included in the National Central Library's online material collection guidelines through the examination of cases from major overseas libraries. Fourthly, after reviewing technical and legal elements such as the definition of collection targets and scope for each new media, and collection methods, we established collection criteria. Fifthly, based on the research results, the policies proposed in this study are as follows: 1) there is a need to establish a clear legal basis for the collection of media platform based materials; 2) the development and presentation of collection guidelines for media platform based materials is necessary; 3) the development of collection tools and infrastructure for media platform based materials is required; 4) for the collection of media platform based materials, it is necessary to obtain permission for collection from targeted social media organizations, and to cooperate in linkage with organizations that produce and service extended reality content; 5) for the service activation of media platform based materials, it is necessary to improve accessibility for the usage activation of these materials, to enhance the content extensibility and ease of use of the e-deposit system including extended reality content, and to advance and construct spaces for reproducing extended reality content.

Recently, many user-participating web services have been used widely as the evolution of internet web technology has rapidly been developed. Users share various content and opinion on line using a site like ‘Social bookmarking.’ Users can share others’ bookmarking history and create tags while bookmarking web sites; we call it collaborative tagging. In this paper, we studied empirical analysis for widely used social bookmarking and collaborative tagging which the result shows minority of users is actively using the bookmarking and a few sites and tags are used by majority of the users. 24% users tagged 80%, 75% sites and 81% tags were tagged below than 3 times. Types of bookmarking activities were found different by users and early appointed tags get more frequency by majority. We also identified relative proportions of tags on certain sites are becoming convergence gradually. We expect the result of this paper will give opportunities to help further developing social bookmarking system.

The purpose of this study is to investigate the determinants of the quality of Web-based legal information services and their significant influences on the user continuance intentions. Based on the main dimensions of the SERVQUAL, this study conceptualizes five dimensions of reliability, assurance, design, empathy, and responsiveness. It measures the level of expectation and satisfaction on the basis of these five dimensions. Regression analysis was conducted to extract and analyze the determinants of the service quality and the factors affecting continuous intention. The level of legal information service quality is superior in empathy, responsiveness, and design category, but it is relatively insufficient in reliability and assurance category. In the reliability category, the relevance of the search results was an issue. The problems related to the authority and information sources were recognized as important. Reliability implies that there is a relatively close relationship between empathy and responsiveness, and that it is necessary to improve the quality of contents such as empathy and responsiveness in order to increase reliability. In order to increase the ongoing use of legal information services in the future, it is more effective to make sure that assurance is top priority.

The purpose of this study investigate the main factors of the diffusion of digital contents and consumer's participation behavior, consumption culture and examine the experiential perspective to consumer's information selection behavior. In digital network, the social presence, challenge, self-presentation, arousal and emotional feeling were significant variables to flow experience. Experiential perspectives focused on the search of identity and self-determination were main basic perspective to explain the diffusion of digital contents, consumer participation. This research result applied to media and device strategy to up-coming digital convergence and adapted to product planning and development, user friendly navigation and emotional human-centered service module.

Recently, as interest in non-face-to-face experiences and services increases, the demand for web video contents that can be easily consumed using mobile devices such as smartphones or tablets is rapidly increasing. To cope with these requirements, in this paper we propose a technique to efficiently produce video contents that can provide experience of visiting famous places (i.e., stage tour) in animation or movies. To this end, an image dataset was established by collecting images of stage areas using Google Maps and Google Street View APIs. Afterwards, a deep learning-based style transfer method to apply the unique style of animation videos to the collected street view images and generate the video contents from the style-transferred images was presented. Finally, we showed that the proposed method could produce more interesting stage-tour video contents through various experiments.

3차원 공간정보는 2차원에 비해 공간적 현실감이 뛰어나기 때문에 최근 경관분석，도시 계획 및 웹(Web) 을 통한 지도 서비스 분야 등에서 이에 대한 관심이 증가하고 있으나，3차원 공간 정보의 기하학적 특성상 기존의 2차원 공간정보에 비해 데이터 량이 방대해 지고 있으며 이를 활용한 또 다른 콘텐츠 제작과 빠르고 효율적인 처리에 많은 문제점을 가지고 있다. 본 논문에서는 이러한 문제점을 해결하기 위한 방법으로 위성 및 항공으로부터 획득한 DEM(Digital Elevation Model)을 이용하여 생성된 3차 원의 지형정보와 도시 모델링 및 텍스처 맵핑 과정을 통해 획득한 정보를 기반으로 하여 각각의 위치에 카메라를 설정하고， 설정된 카메라 위치를 기반으로 Camera Matrix를 구한다. 이렇게 획득한 카메라의 정보엔 깊이 정보를 포함하고 있는데，깊이 정보를 기반으로 하여 3차원의 워핑(Warping)작업을 통해 계층적 핍이 영상(LDI)를 생성하고，생성된 계층적 깊이 영상을 이용하여 3차원의 공간정보를 구현한다.
