Hypermedia documents include structural information for their documents There have been researches on storing and searching hypermedia documents using the structural information of the documents. For the purpose of presenting hypermedia documents, however, only a few models have been proposed. In this paper, we propose a new object-oriented model based on the structural information of HyTime documents for storing and also presenting efficiently the documents. For this modeling, we consider an application of HyTime, a system for a news-on-demand service that provides news customized by user requests. Our modeling can be applied to several Hypermedia application areas, like as customized web-based instructions and digital libraries as well as news-on-demand services.

표는 중요한 정보를 함축적으로 담고 있는 문서 요소로서 문서 영상에서 표의 내용과 구조를 분석하고 이해하려는 연구가 많이 진행되어 왔다. 이러한 표의 검출과 인식에 관한 기존의 연구들은 평판 스캐너로 취득한 문서 영상을 대상으로 이루어졌는데 최근에는 디지털 카메라와 스마트폰이 보급됨에 따라 평판 스캐너 대신 카메라를 이용한 표 인식의 필요성이 대두되고 있다. 따라서 본 논문에서는 카메라로 획득한 문서 영상에서 표 인식에 대한 알고리듬을 제안한다. 먼저 표가 선들의 집합으로 이루어져 있다는 가정 아래 문서 이미지에 존재하는 선을 이진화와 강인한 곡선 맞춤 알고리듬을 사용하여 검출한다. 검출된 선들의 교차점은 표의 요소일 수도 있으며 오검출의 결과일 수도 있는데 교차점 주변의 관찰 결과와 교차점 사이의 연관 관계를 에너지 식으로 표현하고 이 식을 최소화함으로써 각각의 교차점에 최적의 레이블을 할당한다. 얻어진 레이블은 표로 유일하게 변환되며 표의 구조를 셀 단위까지 추정할 수 있다. 다양한 표 영상에 대한 실험 결과를 통하여 제안한 방법이 문서영상의 기하학적인 왜곡에도 불구하고 영상에 존재하는 표를 성공적으로 인식함을 보여준다.

With explosive growth in the area of the Internet and IT services, various types of e-documents are generated and circulated. An e-Document is a sort of electronic records which a organization performs works and goals. In this study, we propose a security algorithm for secure use and distribution of e-documents. Especially, the proposed method can be applied to generate digital signature which can guarantee authenticity, integrity, confidentiality of an e-document and authenticate authorized users. Also, we can get higher security level as using a smart card that provides highly storing capacity and security. We carried out an experiment to verify efficiency and security of the proposed method.

Channel of distribution of contents of digitalised multimedia contents is changing in form passed directly to consumer from manufacturer through digital network of high speed. Together, diffusion of various digital equipment that do is changing Past multimedia consumption structure with the wonderful speed so that can consume easily digital contents. Specially, Multimedia Personal Computer and fast diffusion of a digital television are acting role such as catalyst that promote easy purchase and consumption of multimedia contents of good qualify. However, this system is no method that can sell digital contents and express right that original owner for the contents can insist nothing but consume. Because consumer can distribute to another person copying contents that buy because of and user can distribute producing ashes again according to necessary field by oneself as well as, can lose meaning for original contents. In this paper, Text editing system for XrML (extensible Rights Markup Language) that describe about integrity of message and entity authentication in addition to necessary rights, fees, condition etc. and this to do fetters XML (eXtensible Markup Language) for copyright protection for digital contents in treatise that see hereupon and use digital contents design and embody.

Tools are needed to have access to more effective information and to select it in the environment of digital information where information pours in. and some of the advanced techniques to make up these tools are metadata and annotation. Annotation additionally records the marks for the supplementary explanation of and emphasis on a specific part of the original text and kas more various merits than metadata in terms of the search and use of digital resources. This research aims at suggesting methods that annotation. which has a range of functions including access to information. its reuse and sharing in the digital surroundings of late, can be applied to digital contents such as web services, digital libraries and electronic books. As to the research method, the case studies of annotation systems applied to web services and digital libraries have been carried out, and the metadata formation of the systems has been analyzed.

Digitalization is creating a variety of changes and innovations in our business environment. In manufacturing, robots have long been used for automation to innovate processing speed and quality. The RPA brings these innovations in manufacturing sites to the office space. The purpose of this study is to improve productivity for simple, repetitive tasks in these office space. For identify the potential of automation related to productivity improvement, I looked at the concept of business automation, and then simulated the five areas of business documentation works with agile methodology. In conclusion, I confirmed that productivity improvement of 97.3% in quality inspection and 31.7% in editorial design is possible, and examined the direction to apply to actual work. Based on these results, future study will explore the application of Intelligent Process Automation (IPA).

With the spread of internet, the digitalization and the knowledge informatization are in progress rapidly. Specially, numerous users make the various works and use the services on the web. For the most part, these works make use of the XML The XML shines the reusing of the documents because it is separated from contents and sues. Also, it can re-define the logic structure of the document for requirement of the developer. However, the XML document’s size is much larger than common text document because it handles the document type and adds numerous tags for representing structure of the document. To utilize the limited storage devices of Palmtop, PDA and so u, it is necessary to compress and handle the documents efficiently. Recently, the compression techniques for efficiently handling and compressing the XML documents are under way to solve this problem. But most of the existing researches don't support the query processing for the compressed XML documents. In this paper, we design and implement the XML compression algorithm that compresses the XML document and Processes the query of compressed XML document faster and more efficiently than previous techniques.
