The demand for map applications in both Web and mobile environments has been rapidly increased with the population of Web and smart phone usage. Web-based map applications are mostly developed on such environments as ArcGIS and MapServer and mobile map applications are developed on such API levels as Google Maps and Yahoo Maps. But many parts of map applications are still constructed by coding because these environments don't support high level of automation. Our MapAppGen that we have designed and implemented enhances the Web-based map application productivity by generating the map related modules that can be applied to the Drupal that is one of popular content management systems(CMS's). Comparing the applications that are constructed by the Drupal-supported GMap or NodeMap, the applications that are constructed by MapAppGen provide information on not only the interested geographical feature but also its related geographical features. MapAppGen uses Google Maps API and Drupal is a module-based system that supports the creation, composition and management of contents. We are now working on automatic generation of mobile map applications with MapAppGen.

This paper is a study on the implementation of MAM(Media Asset Management) to utilize UHD contents as high quality broadcast material. The implementation method of this paper is to separate MAM roles with content management functions and transmission workflow functions from workflow, metadata and system interface related work, which are divided into core MAM and MAM-Ex structure. Through the method proposed in this paper, we improved the content management method by applying the page menu method to the material metadata modification and applying the template method to the material structure API. In addition, the storage of UHD material and the configuration of the component server are pooled without any distinction of channels, thereby enhancing the security of UHD transmission assets by minimizing the movement of contents together with broadcasting material protection.

In this paper, I presented that transformation of library from the collection management to knowledge contents management along with paradigm shift under the web-based multimedia information environment is required. Effective web contents management call maximize users'satisfaction with personal customizing services for library users. Especially, contents customizing service using the metabrowsing service contributes to maximize the user'satisfaction by supplying core contents that the user seeks. In this paper, I studied the scheme of knowledge contents management to increase of user'satisfaction, concentrating on the management factors of web-based multimedia knowledge contents and service strategy.

In modern society, which boomed it became easier to obtain the necessary information to the emergence of a variety of smart devices. Due to this, the frequency of using the content based on the Web is growing rapidly. In addition, companies are turning into a production and modify the content using the CMS under the web-based. It can be a very important part to provide users with the content. Currently web services are designing a UI to the device and provided. To improve the ease of use, they are enhancing services only by survey and analysis of the patterns of all users. Most are designed without considering the UX only in the technical aspects. In this paper, to break the limits that apply to all users of the Web service pattern analysis, we propose a visualization system via the animation based on the individual user's movement patterns and usage patterns. Through this convergence is expected to be able to transform the web from the central manager to the user UX and the planning aspects researchers.

스마트 폰 사용자 수가 2000만명 이상이 됨에 따라 모바일 맵 서비스에 대한 수요가 급증하고 있다. 한편, 모바일 기반의 맵 응용의 개발을 위해선 WINDEV Mobile 17과 같은 유료 개발 환경이 있지만 자동화 지원 경도가 미약하여 맵 응용의 생산성이 떨어지고 유지 보수 기간도 많이 소요된다. 우리가 설계하고 구현한 MobileMapGen은 GoogleMaps API를 사용하며 서버 측을 위해 CMS(Content Management System)인 Drupal 환경에 사용 가능 한 모듈들을 생성하고 클라이언트 측엔 iOS 앱을 생성해 맵 응용에 대한 생산성을 향상시켜 준다. 맵 컨텐츠와 그와 연관된 컨텐츠들을 함께 제공하는 모바일의 맵 응용 생성기인 MobileMapGen과 달리 WINDEV Mobile 17, MobilForms, 그리고 VisualStudio.NET는 맵 인터페이스를 지원하지 않거나 위치 정보 형태만을 표시한다. 그렇기 때문에 사용자가 원하는 지형/지물 컨텐츠 타입을 생성하거나 맵 상에 표시하고 관심의 대상인 지형/지물과 연관된 컨텐츠들을 검색할 수 없다.

Digital tourism is the digital support of the tourist experience before, during and after the tourist activity[1]. The GPS-enabled mobile phones provide location-based mobile applications such as tour guide and storytelling services. In this paper, we propose the smart tour guide service platform based on GIS and develop the mobile application to provide the smart tour guide service. The proposed smart tour guide service platform consists of CMS, the multi-modal navigation system, the tour attraction content creation and management system, the tour commodity creation and management system, the smart search system, and the user terminal. The smart tour guide application supports digital tourism in the pre-tour, during tour, and post-tour using the proposed smart tour guide service platform in the popular tourist attractions in Jeju.

Google을 시작으로 포털 사이트들이 Maps API를 공개하면서 맵 응용에 대한 수요가 급증하고 있다. 맵 응용의 개발은 대부분 수작업으로 이루어지고 있기 때문에 맵 응용의 생산성이 떨어질 뿐만 아니라 유지 보수에도 많은 시간과 노력이 요구되고 있다. 우리가 설계하고 구현한 MapAppGen은 ModuleGen, IndexGen, MapGen으로 구성되며 맵 응용을 자동으로 생성한다. MapAppGen은 Google Maps API를 사용하여 CMS(Content Management System) 중의 하나인 Drupal에 적용 가능한 모듈들을 생성해 맵 응용에 대한 생산성을 향상시켜 준다. MapAppGen처럼 맵 응용을 위해 Drupal 모듈을 생성하는 생성기는 현재 존재하지 않으며 Gmap이나 NodeMap과 같이 고정된 맵 인터페이스 모듈들은 존재한다. 그러나 Gmap이나 NodeMap 모듈은 Drupal의 기본 컨텐츠 타입 모듈에 의존하기 때문에 사용자는 원하는 지형/지물 컨텐츠 타입을 생성해 활용할 수 없고 지형/지물들을 유형별로 맵 상에 표시하고 연관된 컨텐츠들을 검색할 수도 없다.

최근의 디지털 사이니지는 대형 고해상도 디스플레이를 이용해 사용자에게 초고해상도 파노라마형태의 볼거리를 제공하거나 사용자와 인터렉션 등을 통해 맞춤형광고를 제공하는 등 다양한 형태로 발전하고 있다. 또 개방형 디지털 사이니지의 발전과 함께 대형 멀티 사이니지를 이용한 초고화질 영상콘텐츠를 다양한 서비스 단말장치의 연동과 웹기반의 상호운용성을 갖춘 관리시스템이 활발히 연구될 것으로 보인다. 본 논문에서는 수십대에서 백여대 이상의 고해상도 디스플레이를 연동하여 초고해상도 영상표출의 기술의 구현방안과 정형화된 영상 해상도가 아닌 초고화질 영상의 개별 콘텐츠에 대한 동기화 시키는 기술을 이용하여 멀티 콘텐츠 플레이 단말기에서 고해상도 영상을 Play Sync하는 기술을 연구한다.

Design and Implementation of Clipcast Service via Terrestrial DMB This paper outlines the system design and the implementation process of clipcast service that can send clips of video, mp3, text, images, etc. to terrestrial DMB terminals. To provide clipcast service in terrestrial DMB, a separate data channel needs to be allocated and this requires changes in the existing bandwidth allocation. Clipcast contents can be sent after midnight at around 3 to 4 AM, when terrestrial DMB viewship is low. If the video service bit rate is lowered to 352 Kbps and the TPEG service band is fully used, then 320 Kbps bit rate can be allocated to clipcast. To enable clipcast service, the terminals' DMB program must be executed, and this can be done through SMS and EPG. Clipcast service applies MOT protocol to transmit multimedia objects, and transmits twice in carousel format for stable transmission of files. Therefore, 72Mbyte data can be transmitted in one hour, which corresponds to about 20 minutes of full motion video service at 500Kbps data rate. When running the clip transmitted through terrestrial DMB data channel, information regarding the length of each clip is received through communication with the CMS(Content Management Server), then error-free files are displayed. The clips can be provided to the users as preview contents of the complete VOD contents. In order to use the complete content, the user needs to access the URL allocated for that specific content and download the content by completing a billing process. This paper suggests the design and implementation of terrestrial DMB system to provide clipcast service, which enables file download services as provided in MediaFLO, DVB-H, and the other mobile broadcasting systems. Unlike the other mobile broadcasting systems, the proposed system applies more reliable SMS method to activate the DMB terminals for highly stable clipcast service. This allows hybrid, i.e, both SMS and EPG activations of terminals for clipcast services.
