This research is aimed to examine the differences through comparative analysis of the Earth Science contents in the science textbooks between Korea and DPRK. The contents of level and scope in science textbooks between Korea and DPRK are analysed by TIMSS frameworks. The results of this research are as follows : 1. The science textbooks of DPRK is lower in quality of paper, printing to that of Korea, and the illustrations, editing design in the textbooks of DPRK are fewer, monochromic and monotonous while those in Korea. 2. The contents of Earth Science in DPRK's science textbooks rank 37.0%, but those of Korea's science textbooks rank 25.5% of the whole textbooks. The learning units related to Earth Science are generally similar to the level and scope in science textbooks between Korea and DPRK. The type of inquire activities in the textbooks of DPRK largely takes on the model experiment, and it was shown that the number of experiments directly made by children is very small compared to Korea' textbooks. 3. There are lots of differences in Earth Science learning terms and predicates used in the textbooks between Korea and DPRK.

The education of 21st century is developed to the closely connected and integrated education, and the ICT applied education is suggested as an approach to teaching-learning method. In this paper, we suggest an teaching-learning pattern and strategy of Technology course as an example of the ICT applied education, and provide an implementation for the efficient XML document creation and storage system of teacher's subject data. And we have confirmed the utilization of this system which it improves the efficient management and preservation of educational data and also it raises the value of educational data by decreasing the burden of re-editing the educational documents for similar business.

On-Line Lectures are becoming more common due to the MOOK service and the expansion of national policy in Korea. Especially, It is being changed to new remote mixed style from traditional lecture in universities. We propose and implement a remote contents making tool with audio synchronization function based on more with less resources. To implement our proposed algorithm, we design an interactive interface to assign multiple cutting intervals and convert an input video to print a new result. In experimental, we can confirm our algorithm works properly with average performance value 9.3% cpu share ratio and 87mega byte ram usage(CPU 2.60GHz, 820*600 Area).

In this paper, we propose a time relation model among media with the concept of time and space under hypermedia environments. The model explains time relations of node proceedings among media by time and proceedings among media connected with link. Using this model, hypermedia system which constructs dynamic nodes with time proceeding is designed and implemented. And this hypermedia system provides editing tool and controllers to edit dynamic node information, link tool to construct associative relations among nodes and navigaton tool to do node movement freely, various time controls and node proceedings.

As social network service platforms grow and one-person media market expands, people upload their own photos and/or videos through multiple open platforms. However, it can be illegal to upload the digital contents containing the faces of others on the public sites without their permission. Therefore, many people are spending much time and effort in editing such digital contents so that the faces of others should not be exposed to the public. In this paper, we propose an automatic face hiding system called 'autoblur', which detects all the unregistered faces and mosaic them automatically. The system has been implemented using the GitHub MIT open-source 'Face Recognition' which is based on deep learning technology. In this system, two dozens of face images of the user are taken from different angles to register his/her own face. Once the face of the user is learned and registered, the system detects all the other faces for the given photo or video and then blurs them out. Our experiments show that it produces quick and correct results for the sample photos.

Problem of compatibility, contents protection, contents circulation etc. was caused between contents offerer and consumers by indiscreet rights technical development about digital contents. Therefore, MPEG-21 framework proposed the REL(Right Expression Language) based on XML(eXtensible Markup Language) by rights expression language for rights management. We designed and implemented of the REL document editing system that rights creation and edit are available efficiently about contents easily without comprehension of MPEG-21 framework and client system that present consumption method of REL document.

In this paper, we design and implement the UCC services prototype system for image and video. The proposed system consists of the two components such as the multimedia processing subsystem and the metadata management subsystem. It provides the API to UCC service developers. The multimedia processing subsystem supports the media management and editing of image and video, and the streaming services of video. The metadata management subsystem supports the metadata management and retrieval of image and video. The reply management and script processing of UCC are given in the subsystem.

본 논문에서는 HDTV 데이터를 입출력할 수 있는 고속 실시간 데이터 저장 시스템을 제안한다. 이 시스템은 ⅰ) 방대한 크기를 HDTV 데이터를 고속으로 입출력할 수 있어야 한다. ⅱ)데이타를 연속적으로 입출력할 수 있는 것 외에 데이터를 비선형적으로 랜덤하게 억세스 할 수 있어야 한다. ⅲ)실시간으로 데이터를 재생하기 위해 일정하게 주어진 시스템 입출력 속도를 항상 만족할수 있어야 한다. 이러한 조건을 만족시키기 위해서 여러 개의 하드디스크를 병렬로 연결하고 데이터들을 각각의 하드디스크에 나누어 저장하였다. 하드디스크의 입출력 성능은 하드디스크 아암의 탐색 동작에 의해 크게 좌우되므로 탐색 동작을 효과적으로 제어할 수 있는 방법이 설계되었다. 제안된 시스템은 주제어부, 데이터 분배부, 종제어부로 나뉘며 각각의 하드디스크는 독립도니 종제어부에 의해 제어된다. 제안된 시스템이 주어진 요구사항을 만족하는지를 확인하기 위하여, 제안된 시스템을 DEVS 형식론을 이용하여 구현하고 시뮬레이션 하였다. DEVS 형식론은 이산사건 시스템을 계층적이고 모듈화된 형태로 기술한다. 시뮬레이션 과정에서 발생된 사건들을 분석하였다. 그 결과 제안된 시스템이 주어진 요구사항을 잘 만족함을 보았다.

In this paper, we propose a terrain processing system that can display real and large terrains. The system integrates real terrain display and interaction, which makes up for the lack of interactive functions in mainstream terrain visualization software. In addition, the system provides functions such as line marking, volume calculation, and contour display.

기업간 비즈니스 거래를 하기 위해서는 B2B(Business to Business)기업이 지원하는 업무 프로세스에 관한 정보와 업무 정보 교환을 위해 기업의 기술적인 사항을 정의하고 거래 기업간에 비즈니스 거래를 위하여 거래 파트너간 합의된 상호작용을 정의한 문서가 필요하다. 이러한 문서를 XML 기반의 개방형 전자상거래 프레임 워크인 ebXML(electronic business XML)에서는 기업의 비즈니스 협업능력을 정의한 전자를 협업 프로토콜 프로파일(Collaboration-Protocol Profile:CPP)이라 하고 거래 기업간에 비즈니스 협업 상호작용을 정의한 후자를 협업 프로토콜 약정서(Collaboration-Protocol Agreement:CPA)라고 한다. 본 논문에서는 ebXML에서 거래 기업간 상호 운용성을 증대시키는 CPP문서를 효율적으로 저작 할 수 있는 생성기와 거래 기업들의 CPP 문서들을 기본으로 상호 협업을 정의한 CPA 문서를 저작 할 수 있는 Composer 시스템을 설계 및 구현하였다.
