Web2.0의 고도화와 소셜미디어의 진화에 따라 웹 기반 콘텐츠에 대한 다양한 활용이 시도되고 있다. 또한, IPTV 부분에서는 기존의 TV기반에서 Web기반, Mobile기반 서비스로 확산되고 있다. 이러한 멀티디바이스 환경과 웹기반 콘텐츠의 IPTV 활용 서비스를 위해서는 콘텐츠에 대한 정의와 이를 표현하기 위한 메타데이터에 대한 정의가 필요하다. 이를 위해서 관련 표준화 단체를 분석한 후 이들이 제공하는 콘텐츠 메타데이터의 연관관계를 비교 분석하였다. IPTV 서비스를 위한 콘텐츠 메타데이터는 TV AnyTime Phase1 을 바탕으로 각 표준기구의 네트워크 상황과 서비스 방식에 따라 선택적으로 적용하고 있으며, VOD 서비스를 위해서는 CableLab의 ADI 메타데이터를 적용하고 있다. 향후 멀티디바이스 환경에서 IPTV 서비스를 위해서는 메타데이터에 대한 확장 연구가 필요하다.

This paper presents a review of standardization activities toward the interoperability between different metaverse platforms, which is a research hotspot in the metaverse. The metaverse is often considered as the evolution of the current mobile Internet. Like for the Internet, interoperability is essential to provide continuous user experiences over different metaverse service environments. However, current metaverses have limitations in providing interoperability in terms of portability of services, digital objects, such as identity and avatars, and economic systems. To address these limitations, the metaverse industry and open-source communities have recently begin to develop metaverse interworking standards. We describe activities conducted by various representative standardization bodies such as the Metaverse Standardization Forum, W3C (World Wide Web Consortium) Open Metaverse Interoperability, Open Metaverse Foundation, Open Metaverse Alliance for Web3, and Metaverse Alliance. In addition, we discuss how to counteract interoperability issues from the Korean perspective.

HTML5-based Web platform is established as a next-generation national standards, Web services provider, has been competitively develop support technology HTML5-based app in smart media devices and smart TV. In accordance with the W3C is an international Web standards development organization, Microsoft, Apple, Mozilla, Google, such as Opera, various Web browser vendors are participating in standardization. Gradually emphasized the importance of HTML5, HTML5 -based Web pages, it is necessary to fast load times when contained a large amount of information. Therefore, in this paper, the initial studies in order to reduce the loading time of a web page, configure each browser-specific same Web page, and measure the initial loading time. Also, one by one remove the HTML5 tags, and CSS property, to analyze the tags and attributes of the account for a large proportion to the initial load time. Through the results, it is desired to provide a process which can reduce the Web page.

Means reducing the gap to prevent discomfort to use information from the perspective of Web accessibility is disabled. The current was strong sanctions that have been implemented from the year 2014 to the beginning Government, the public policy of the Web Accessibility Web accessibility compliance obligations. According to 2013 data of the Korea Information Security Agency is only half that of the general public by 28.8% to 100% of the domestic SNS public utilization. Began to cause a change in the web environment and the emergence of mobile SNS. And is a factor that interferes with utilization of the informational content to be neglected Prosumer the environment of their production is consumed too quickly, rapidly problem. Let's start from the idea that we provide a convenient tool for Web accessibility is not an issue on the web site accessibility standards of the project is to create these problems.

Recently the huge demand for Internet media streaming has dramatically increased the cost of the CDN (Content Delivery Network) and the need for a means to reduce it is increasing day by day. In this situation, a P2P-assisted DASH technology has recently emerged, which uses P2P (Peer-to-Peer) communications based on WebRTC (Web Real-Time Communication) standards to reduce the CDN cost. This paper proposes an algorithm that can significantly improve CDN cost savings in this technology by selecting peers based on the transport history. Also we implemented this algorithm in an experimental system and, after setting experimental conditions that emulate the actual mobile network environment, we measured the performance of the experimental system. As a result, we demonstrated that the proposed algorithm can achieve higher CDN cost savings compared to the conventional algorithm where peers are selected at random.

With the development of recent IT is spreading and dissemination of smart terminals, telemedicine and electronic medical records (EMR) and other common anywhere due to medical advances are being digitized environment. This trend is in line with the information to take advantage of smart terminals in the mobile medical information system increasing. In this paper, the recent trend to examine healthcare information technology standardization, predicting the future prospects look healthcare information systems. In addition, the security of mobile medical information system, to look at aspects of mobile-based health information systems in the country's need to discuss the trends and standards.

최근 모바일 디바이스의 성능향상으로 모바일 웹 애플리케이션 구동환경이 개선되고 있다. 이에 따라 모바일 웹 애플리케이션 개발 수요가 국내외적으로 증가하고 있다. 하지만 기존 PC환경과 달리 개발 환경 및 표준에 대한 고려가 적어 많은 개발비용이 소모되고 있다. 본 논문에서는 MWeb-프레임워크를 통해 최근 각광 받고 있는 웹 개발 프레임워크 기반의 개발방법론을 제안하며 이와 더불어 다양한 디바이스에서 동일한 사용이 가능하도록 모바일 웹 표준을 준수하는 개발방법론을 제안한다. Ruby on Rails기반의 모바일 웹 개발 아키텍처를 정의하고 이를 바탕으로 모바일 웹 표준을 준수하는 애자일 개발방법론을 적용한 프로세스 모델을 제안하고 기존 웹 개발 프레임워크와 개발방법론을 비교, 평가한다. 제안한 프레임워크를 통하여 신속한 개발을 수행할 수 있으며 모바일 웹 표준 환경을 준수하여 모바일 웹 애플리케이션의 품질과 신뢰성을 획득할 수 있다.

최근 모바일 디바이스의 웹 접근 환경이 PC환경과 동일한 프로토콜을 이용하는 형식으로 변화하고 있다. 이에 따라 많은 곳에서 모바일 웹 애플리케이션을 개발하고 있으나 모바일 웹 표준을 도입하여 개발을 수행하는 곳은 많지 않다. 본 논문에서는 최근 각광을 받고 있는 경량화 웹 애플리케이션 개발 프레임워크인 Ruby on Rails[1]를 기반으로 하여 최근 W3C에서 정의된 모바일 웹 표준을 준수하는 애자일 개발방법론을 제안한다. Ruby on Rails기반의 모바일 웹 개발 아키텍처를 정의하고 이를 바탕으로 모바일 웹 표준을 준수하는 애자일 개발방법론을 제안한다. 제안한 프레임워크를 통하여 개발을 수행할 경우 애자일 개발방법론을 도입함과 동시에 모바일 웹 표준 환경을 준수하여 모바일 웹 애플리케이션의 품질을 보증할 수 있으며 신뢰도도 획득하게 된다. 또한 다양한 디바이스에서 정상적인 구동이 가능하다.

With the spread of wireless internet, the interest in mobile applications and services is increasing. Korea Wireless Internet Standardization Forum has been establishing the standards for mobile platform and map service in the wireless internet environment. This study aims to present a paragon of mapping middleware that plays the role of broker for wireless internet map service: in particular, it focuses on the interoperability with generic map servers. In this study, we developed a method for applying current map servers to the wireless internet map service, and analyzed the request/response structure of the map servers which have different operation characteristics in order to allow our middleware to fully utilize the functionalities of the map servers. The middleware we developed is composed of .NET-based XML Web Services: it has a lightweight module for image map and a map representation module for choropleth map, symbol map, chart map, etc. This mapping middleware is a broker between mobile client and generic map server, and supports .NET clients and Java clients as well. Its component-based interoperability grants the extensibility for the wireless internet dedicated map servers of the future in addition to the current generic map servers.

This study seeks to establish a ubiquitous wardrobe with a clothing management function through detailed and subdivided integration research. To create a database, a survey was conducted, and the output data were analyzed and used as the basic data. In particular, this study researched clothing management programs and companies' standards of clothing product classification systems. First, through an in-depth analysis centering on specialists, we established the contents of a ubiquitous wardrobe and used the concept of cloud computing to support the wardrobe contents and smart phone applications. Second, this research found significant differences between individuals, schools, and enterprises in their applications of, and the importance they attach to, design images. A detailed database composed of various categories was established to present the ubiquitous wardrobe contents with efficient functions. Third, we facilitated the search process by designating clothes with QR codes, which is one of the functions of contents. Fourth, the code numbers generated in the process of entering clothes into the database were utilized as RFID information as a way to arrange the products in a simpler manner. The ubiquitous wardrobe was constructed as a web-style hybrid, and its contents areavailable through mobile applications and QR codes.
