Moving picture has become the important media in education with expanded e-learning paradigm, but Korea Educational Metadata has limitation about representing information of lots of events and objects in moving picture. Announcing the MPEG-7 specification the information of lots of events and objects in it can be presented in terms of semantic and structural description of moving pictures. In this paper moving picture searching system model that integrates two metadata specifications, such as KEM and MPEG-7, is proposed. In this model one ontology to combine two metadata specifications is designed, and the other ontology about knowledge of a subject matter is added to search efficiently in searching system. As some moving picture data from Edunet were selected and stored in our server, our prototype of searching system using MPEG-7 and KEM shows the results that we are expected.

The objective of this study is to analyze educational web-sites and digital contents for elementary music class according to the 2015 revised music curriculum. First, the current status of educational web-sites that are most actively used in music class were reviewed. And the characteristics of the digital contents included in the web-sites for music education were analyzed. the primary analysis was about the service of the web-sites, and the secondary analysis was about the type of digital contents and the contents of music education. The most actively used web-sites in music classes were Edunet T-Clear, T-Sherpa, i-scream, Indischool, which differed slightly from the web-site's services and the type of digital content and contents. Specifically, the main functions for supporting music classes, the reflection of the curriculum contents, the systematicity of the materials, the objectivity and the on-site nature, and the connection with other subjects appeared differently. In order to effectively utilize digital contents in elementary music class, first, expertise of teachers for timely use of web-sitesand digital contents is required. Second, the development and utilization of various digital contents for the nature of music education is required.
