Recently, the needs for the virtual reality service of multimedia contents on the web are increasing. The services are provided by the parameter value of attribute informations of the contents. The Conventional method for managing the parameters is storing the informations separately for the contents, in this method managing and implementing the system are to be costing job. In this paper, a virtual reality service based on meta data is proposed. For the storing and managing the parameter information, we use the free space of the JPEG images. And for testing the effectiveness of the proposed system, we implemented the prototype virtual reality service model.

인터넷 발달로 인한 정보격차는 장애인들의 문화지체현상을 가속화 시키고 있다. 이에 웹사이트의 원스톱 서비스에 있어 경험에 기초한 디자인과 보편적 디자인을 기반으로 접근성을 확장해 나가야 할 것이다. 본 연구에서는 문헌을 통해 장애인을 위한 접근성 필수항목 7가지, 즉 콘텐츠구성, 키보드접근, 마우스접근, 이미지처리, 텍스트처리, 색, 코드를 선정하고 이를 근거로 장애인 자료실이 있는 공공도서관과 그렇지 못한 공공도서관, 해외 공공도서관의 웹사이트를 대상으로 평가하였다. 이를 토대로 접근성 확장을 위해 메인페이지 개선, 사용자 경험을 기초한 콘텐츠 구성, 콘텐츠의 접근성, 의미 있는 마크업, 이용자를 위한 맞춤형 콘텐츠, 제작 권장사항 등을 제안하였다. 앞으로 장애인을 포함한 모든 이용자를 위한 웹 접근성 지침은 경험적 데이터와 보편적 디자인에서 이루어져야 할 것이다.

Recently, an interest in a mobile search is increasing according to the growing propagation of smart phones. However, a keypad, which is not appropriate for mobile environment, is the only input media for the mobile search. As an alternative, voice emerged as a new media for the mobile search, but this also has weaknesses. Thus, in the paper, we propose a mobile content called Orthros for searching the Internet using images as an input. Orthros extracts texts from images, and then inserts the texts to public search engines as a keyword. Also, Orthros can repeat searching with the extracted texts by storing result URL to internal databases. As an experiment, we analyze properties of recognizable images and present the implementation method in details.

DRM은 디지털콘텐츠의 지적재산권이 디지털 방식에 의해서 안전하게 보호. 유지되도록 하여 디지털콘텐츠의 창작에서부터 소비에까지 이르는 모든 유통 시점에서 거래규칙과 사용규칙이 지속적이고 적법하게 성취되도록 하는 기술이다. DRM은 디지털 형태로 유통되는 문서, 음악, 비디오, 게임, 소프트웨어, 이미지 등의 각종 디지털 콘텐츠를 불법 복제로부터 안전하게 보호하고, 콘텐츠 서비스의 유료화를 가능케 하는 기술 및 서비스를 말한다. 또한, 콘텐츠 자체와 보안과 저작권 보호뿐만 아니라 콘텐츠의 생성${\cdot}$유통${\cdot}$사용${\cdot}$관리에 필요한 모든 프로세스를 제어할 수 있게 해준다. 본 논문에서 구현된 기술은 암호알고리즘을 사용하여 함수의 위치 및 내용에 쉽게 접근할 수 없고 소프트웨어의 불법적인 분석 시도를 어렵게 하였다.

With the development of next IT convergence technology and the construction of infrastructure for personalized healthcare services, the importance of services based on user's preference is being spotlighted. Healthcare service have been progressed as treatment and management for specific diseases and dietary nutrition managements to customers according to the increase in chronic patients. In this paper, we proposed the personalized dietary nutrition contents recommendation using the hybrid filtering for managing health. The proposed method uses the hybrid filtering through combining the collaborative filtering and the image filtering in order to reinforce the special trend that recommendation provides similar contents. We developed the Web application for this purpose, and experimented with it to verify the logical validity and effectiveness. Accordingly, the satisfaction and the quality of services will be improved the healthcare by recommending the dietary nutrition contents. This evaluation found that the difference of satisfaction by service was statistically meaningful and showed high satisfaction.

Major purpose of brand establishment of city is to give pride for the citizen and to enhance the city value through improving city image. As modern society wants aggressive and active attitude from all fields, the city, which means as human place of residence, has to try to change for human life and prosperity. It is true that the establishment of brand is shown through politics, economy, society, culture and art, however travel effect and profit creation should be most important. In actual circumstance of our country, that travel deficit is getting increased. the brand establishment of city is more concerned. To build a city, history and time is essential elements. It may be impossible that consistent direction and meaning continue throughout long terms, but after all, the kernel of tourism contents is that idea and development is concentrated focusing consistent direction and meaning. To solve this, problem of strategy and direction was researched through analysis of foreign cities, and also understanding of future role of city in 21st century make a base for rebirth as international travel city. After city brand establishment based on continuous management, it is very important to make city which has strong image power.

The study designs and implements a KORMARC/EAD integrated system for the Myongji Digital Library Collections. The purpose of this paper is to design the metadata to Myongji Korean History Collections to provide digital information of high quality to clients, and to develop and implement a model for managing digital library collections. In order to test the model and the quality of the derived metadata, we built a metadata management system, which is connected to the existing KORMARC system. The system consists of two modules- a retrieval and an input module. While in the retrieve mode, one can retrieve KORMARC records of books and archival items, with links to modified EAD files for archival items or to image files for books, in the input mode, one can type two types of data such as a catalog data and an inventory data. Finally, we evaluated the proposed system via mail questionnaires, and propose three suggestions to make this system a much more comprehensive and effective system.

방송 제작 환경은 고품질의 콘텐츠를 빠르고 효율적으로 서비스하기 위하여 IT 기반 시스템으로의 전환을 진행하여 완성 단계에 이르렀으며, 대부분의 방송 콘텐츠는 파일 기반으로 제작 및 보관되고 있다. 과거 테이프 기반에서 파일 기반 콘텐츠로 전환되면서 신호 레벨로 진행되던 전통적인 품질 관리에 대한 새로운 방안이 요구되었으며, 이를 위하여 파일 기반 콘텐츠에 최적화된 콘텐츠 품질검사 시스템 개발이 진행되어 왔다. 이미지 처리에 기반하는 오류 검출 알고리듬의 복잡성으로 인하여 실시간 검사를 지원하지 못하여 HD 실시간 시스템에의 적용에 어려움이 있었으며, 대용량의 아카이브 시스템에서는 품질검사 시간에 대한 단축이 지속적으로 요구되고 있다. 이에 본 논문에서는 방송 환경에서 발생하는 블록 오류 등 다양한 A/V 오류를 고속으로 검출하기 위하여 최근에 급부상하고 있는 GPU 기반의 병렬처리를 이용하는 품질검사 실시간 고속화 시스템의 구현에 대하여 기술하고자 한다.

In AI chatbot service via a messenger, a profile image of the chatbot is the first thing that users see to communicate with the chatbot. This profile image not only manages an impression about the profile owner in SNS on followers, but also makes an important impression about chatbot services on users. Thus motivated, this study investigates proper profile images tailored for the types of chatbot services and users. Specifically, I reviewed the preferred images and expressions of chatbots for each purpose of chatbot service. Then, in a case study, I collected and analyzed the representative chatbot profile images for the purpose of fun and counseling. The profile images are categorized as robot, human, animal, and abstract images. Based on these categories, I surveyed the preferred profile image of the chatbot service in either the text type or image type alternatives. For the purpose of fun, in the text version, I found that both men and women preferred a human image to others. However, in the image version, men preferred woman and robot images while women preferred cute animation character and robot images. For counseling services, both men and women preferred woman and animal images most, which is similar to the results of the text version of questionnaires as well. While both genders consistently preferred real photo images, women tend to like abstract images more than men do. I expect that the results of this study would be useful to develop the proper profile images of AI chatbot for each service purpose.
