PISA의 연구 결과에 따르면 컴퓨터 활용 빈도나 ICT 활용 환경 등의 양적 활용 실태는 세계적인 수준이나 프로그램이나 소프트웨어 활동 등의 컴퓨터 질적 활용 정도는 제고될 필요성이 있는 것으로 나타났다. 이는 초등 컴퓨터 교육에도 시사하는 바가 크다. 하지만 인적 물적 여건 등으로 인해 프로그래밍 교육을 초등학교 현장에 바로 적용하기에는 무리가 있다. 따라서 본 논문에서는 언어의 복잡성이 낮고 프로그래밍 단계와 과정이 간단한 HTML을 현장에 효과적으로 적용하기 위한 텍스트 에디터를 개발하고 개선점을 찾아보았다. 텍스트 에디터는 우선 태그를 직접 칠 필요가 없으며 학생들이 쉽게 학습할 수 있도록 도움말을 제시해 주었고 간단한 이미지 뷰어 기능을 통해 쉽게 이미지를 넣을 수 있도록 하였다. 개발된 텍스트 에디터의 효과를 설문지로 조사한 결과 쉽게 HTML 문서를 작성할 수 있어 학습에 도움이 된다는 점과 도움말을 제시한 부분은 긍정적으로 평가된 반면 보다 UI를 좀더 개선해야 한다는 결과가 나왔다.

스마트폰, 태블릿 PC 등 모바일 기기의 급속한 보급 확대에 따라 모바일 앱 마켓 또한 급속도로 성장하고 있다. 현재, 다양한 종류의 앱들이 모바일 마켓을 통해 유통되고 있으며 그 중 생산성 증대와 관련된 일정관리, 노트, 문서 파일 뷰어 등은 다운로드 순위에서 항상 상위를 차지하고 있다. 따라서 본 논문에서는 일정관리를 위한 시간표 기능과 스마트 폰의 무음 처리 기능을 한데 결합하여 회의나 중요한 모임시 상황에 따른 적합한 수준의 스마트폰 작동 제한을 통해 생산성 증대를 꾀하는 자동 사용제한 어플리케이션을 설계하고 구현하였다.

인터넷 이용자 급증으로 정보들은 무한히 생산되고 사방에 산재되어 가고 있다. 이로 인해 정보들을 탐색하는 시간은 계속 증가하고 있다. 특히 공지사항이나 날씨처럼 반복적으로 갱신되는 정보들을 얻기 위해 사람들은 동일한 정보를 주기적으로 검색하고 있으며 이에 따른 불필요한 트래픽 유발 및 검색시간이 낭비되고 있는 실정이다. 본 논문은 동일한 정보를 주기적으로 검색함으로써 야기되는 문제점을 서술하고 이를 해결하기 위해 다수의 웹상에서 각종 정보들만을 추출하여 하나의 웹페이지 내에 배치하는 웹 컴포넌트를 설계 및 구현한다. 이 시스템을 사용한다면 사용자는 단순히 하나의 웹페이지를 클릭함으로써 다수의 웹상에 저장된 정보들을 웹서핑 없이 얻을 수 있기 때문에 정보검색 시간을 크게 단축시킬 수 있다. 이 시스템을 구현하기 위해 크로스 도메인상의 웹문서에서 정보를 추출하고 조작하는 것을 금지하는 웹 표준 정책인 동일출처정책을 우회할 수 있는 방법을 서술하였으며 이 정책을 회피함으로써 파생되는 문제점과 해결방안을 서술하였다. 마지막으로 현존하는 관련 시스템들과 비교하여 우수성을 보인다.

As the complexity of Web applications have increased significantly, the approach using frameworks such as Cocoon, Struts, JSF, is being suggested to develop Web applications more Quickly and efficiently. However, it Is difficult for beginners to write Apache Cocoon Sitemap files in XML. We implement a Cocoon Sitemap editor on the Java Servlet engine that allows beginners to write Cocoon Sitemap files more easily. Our system consists of three parts: Sitemap Main editor, Pipeline Viewer, and Sitemap Tracer. Sitemap Main editor support users to write BML configuration documents, so-called Sitemap file, that defines all the components pipelines, generators, and other configuration information for a Cocoon application. pipeline Viewer support users to catch the structure of Cocoon component pipelines by the medium of graphical interface. Sitemap Tracer have features to monitor of SAX events through Cocoon pipelines in a Sitemap file.

XML is a meta-language as SGML and also can be xonsructed as an Internet versionof simplified SGML being used in confunction with XLL. Xpointer and XSL. Also W3C established DTDless Well-Formed XML document to use XML document on the Web. But it isnt offered system that consists of browsing, link and DTD generating facihty, and efficiently processes DTDless Well-Formed XML document. This paper studies on an implementation and design of system to process DTDless Well-Formed XML document on the client-side. This system consists of Well-Formed XML viewer displaying Well-Formed XML documet, XLL Processor processing Xll and Auto DTD generator constructing automatically DTDs based on multiple documents of the same class. This study focuses on automatic DTD generation during hyperlink navigation and an implementation of extended links based on XLL and Xpointer. ID and Xpointer location address are used as the address mode in the links. As a result of implement of this system, it conforms to validationof extended link facihties, extracts DTD from Well-Fromed XML Documents including same root element at the same class and constructs generalized DTD.

PDF is widely accepted as a standard document format and now it supports 3D contents as well. Within the engineering application areas, this new 3D feature may be used to support sharing of 3D documents and thus collaboration between engineering departments, suppliers and partners. In this paper, we describe a system that automatically generates formatted engineering documents including 3D data converted from 3D applications such as commercial 3D CAD viewer. The system consists of two major modules. One is U3D conversion module and the other is PDF conversion module. U3D conversion module extracts geometry, view data, assembly and disassembly information from 3D viewer and converts to U3D format, currently in IDTF text file format. PDF conversion module generates a PDF file and inserts U3D data, various annotation information, and scripts for custom generated operations such as assembly and disassembly in the PDF document.

Database query and reporting tools, OLAP tools and data mining tools are typical front-end tools in Business Intelligence environment which is able to support gathering, consolidating and analyzing data produced from business operation activities and provide access to the result to enterprise's users. Traditional reporting tools have an advantage of creating sophisticated dynamic reports including SQL query result sets, which look like documents produced by word processors, and publishing the reports to the Web environment, but data source for the tools is limited to RDBMS. On the other hand, OLAP tools and data mining tools have an advantage of providing powerful information analysis functions on each own way, but built-in visualization components for analysis results are limited to tables or some charts. Thus, this paper presents a system that integrates three typical front-end tools to complement one another for BI environment. Traditional reporting tools only have a query editor for generating SQL statements to bring data from RDBMS. However, the reporting tool presented by this paper can extract data also from OLAP and data mining servers, because editors for OLAP and data mining query requests are added into this tool. Traditional systems produce all documents in the server side. This structure enables reporting tools to avoid repetitive process to generate documents, when many clients intend to access the same dynamic document. But, because this system targets that a few users generate documents for data analysis, this tool generates documents at the client side. Therefore, the tool has a processing mechanism to deal with a number of data despite the limited memory capacity of the report viewer in the client side. Also, this reporting tool has data structure for integrating data from three kinds of data sources into one document. Finally, most of traditional front-end tools for BI are dependent on data source architecture from specific vendor. To overcome the problem, this system uses XMLA that is a protocol based on web service to access to data sources for OLAP and data mining services from various vendors.

In order to use the VR HMD, operation through separate controllers in both hands is required. Methods for text input in VR include a method of selecting virtual keyboard keys on the screen one by one using a controller, a method of inputting through a keyboard that is a resource of a computer by connecting a computer and VR, or a method of inputting through a keyboard that is a resource of a computer by purchasing a wireless keyboard in VR and wireless keyboard connection method. As such, the text input method in current VR equipment causes inconvenience and additional costs to users. For these reasons, most of the VR-related contents are limited to simple functions such as games or viewers, and there is a risk that VR equipment will be recognized as a simple game machine. Therefore, in this study, a multi-input interface using hand tracking provided by the Oculus Quest2 device is designed and partially implemented. Through this, it is expected that various tasks such as document work and business processing as well as games can be conveniently used using VR equipment.
