인터넷의 발전으로 웹 서비스를 사용하는 사용자가 기하급수적으로 늘어났고 사용자에게 다양한 서비스를 제공하기 위해 많은 기술이 등장하고 있다. 서비스를 받는 사용자의 웹브라우저에서도 서버의 많은 기술을 구현할 수 있는 공간을 제공하고 있는데 바로 Web Storage와 Indexed DB이다. Web Storage는 용도에 따라 수 MB 정도를 사용하지만 많은 양의 데이터를 구조화하여 사용한다면 Indexed DB가 적합하다. 하지만 Web Storage뿐만 아니라 Indexed DB 역시 영속적이고 평문의 데이터를 저장하고 있다. 이러한 데이터는 웹 보안에 취약하여 XSS 등의 공격에 사용자의 데이터가 노출되어 탈취되거나 편집되어 악용될 우려가 매우 크다. 본 논문에서는 이와 같은 취약점을 보완하기 위해 운영체제와 디바이스 정보를 이용하여 사용자를 인증하고 암호화하는 기법을 구현하여 성능평가를 하였다.

The his paper describes Management System of Environment GIS Data using JVM, JDBC, Oracle DB. Environment GIS data using the system are satellite Image, Thematic Map, GIS Data. The data have spatial information and attribute information. The search supplies spatial search using viewing-map on Web browser, nonspatial search using the attributes of data. The registration of data use the registration system of data on Web browser.

To help the blind to find the information easily on World Wide Web, this research has tried to develop the device which enables us to convert HTML for the general into HTML for the blind. This program consists of the items as follows: 1. Web Robot to gather the internet browser and the general HTML. 2. Restoring DB by Parsing process 3. Multimedia editor for the use of web DB to add the literal and acoustic description to the editing function. 4. Convertor which gathers the DB and then changes into HTML for the blind. This project is designed to make it easy for the manager to establish the web site for the blind. We expect that this program will basically help the blind to overcome the inequality in the common information.

Business model in Web environments is usually provided by digital data. Information exchange of users and service providers should be performed by encryted data. Encrypted protection. In this paper, We have prevented using contents by users is not accessed based on RBAC. in this paper, We propose a new DB encryption scheme which use RBAC and digital signature based on PMI.

센서 네트워크 노드는 각각 초저전력, 초소형, 저비용을 지향하는데 이러한 하드웨어 리소스를 사용하는 임베디드 OS가 TinyOS이다. TinyDB는 이러한 TinyOS 센서 네트워크로부터 정보를 추출하기 위한 쿼리프로세싱 시스템이다. 이러한 TinyDB를 활용해서 X-Scale 기반의 임베디드 리눅스 환경에서 네트워크를 통한 Host서버와의 연계 및 센서 네트워크 응용에 관한 연구를 하였다.

최근 인터넷과 정보통신기술의 발달로 정보검색시스템과 DB의 구축 및 정보서비스가 급격하게 증가하고 있다. 인터넷의 등장과 함께 DB 검색은 도서관이나 정보센터는 물론 일반 국민들에게도 생활화되어 가고 있다. 따라서 늘어나는 DB 중 검색목적이나 필요에 적합한 DB를 선정하여 효율적으로 이용하는 일이 점점 더 중요해지고 있다. 이와 같이 적합한 DB를 선정하여 효율적으로 이용하는 일에는 정보검색시스템이나 DB에 대한 올바른 평가가 전제되어야만 가능한 일이다. (중략)

The purpose of this study is to develop Web database for healthy city that contains healthy city indicators for making city health plans, setting project priorities, monitoring projects, and evaluating healthy city projects, effectively. Using Delphi survey method for identifying indicator domains and indicators, we extracted nine domains with thirty-four healthy city indicators. Based on the appraisals of DB users about the contents of DB, a web database for healthy city Wonju was constructed. We developed a web database system for the purposes of sharing high quality health related data for managing and evaluating healthy city projects. The web database currently provides variety data in the web address, http://healthycity.wonju.go.kr/index.html. The web DB comprised with major healthy city indicators that are the most important indicators, healthy city indicator data that have a variety data set for encompassing all domain areas such as city infrastructure, health medicine, economies, and all other related areas and qualitative data that contains policy reports, research results, healthy city information and all other tips. A database of healthy city is very essential and important because it makes healthy city projects alive by managing and sharing healthy city related data effectively. But we need to fill out some blank cells in DB because there are currently unavailable data for some indicators. In conclusion, we expect the web DB contributes information sharing of healthy city project teams and improving healthy city project quality at Wonju city in Korea.

There are currently tremendous amount of geotechnical information saved, which has been qcquired for essential application of site selection, plan, design, constructin, repari in the builing work. However, due to the lack of the location data attribute, there has been a trouble in its analysis and GIS implementation. In this study, the geotechnical information aquisition program(PGeo) for real-time database in the field and geotechnical information reporting program(GeoReport) by Web-GIS for additional data input and its reporting function has been developed.

The Ministry of Construction and Transportation (MOCT) has been constructing a nationwide soil information DB since 2000, as basic data for the construction of 'underground geographical information,' a project under the 2nd National Geo-spatial Information System (NGIS) master plan. The inputted soil information includes not only underground conditions such as the layer depth, type, color, and groundwater level, but also engineering information that can be applied to construction work design, such as on the standard penetration test and the compression test. It is difficult to use this information in soil analysis and design, however, because only the test results are currently available. A web-based geo-spatial information system was developed in this study to facilitate the effective application of the soil information database (DB). First, the space information, layer information, and engineering test information were loaded from the soil information DB in real time, and the earth volume, bearing capacity, and settlement were calculated to develop a web client that will evaluate the ground softness and liquefaction. It seems that the soil information DB can be actively applied to the planning and design of construction works using this system.
