In this paper, NMEA based Parser programming for Smart-phone was designed at a GPS receiver. The design scheme for Map API and sensor web services was designed according to the Google Map API standards that the position values of NMEA sentences were changed due to XML files. As a result of interfaces between GPS NMEA sentences of Smart-phone and Google Map API, it is possible that real time visual positioning sensor web services about the Google Map mapping from a GPS receiver could be worked on web sever.

Although the multi-scale map database should be constructed for the web map services and location-based services, much part of generation process is based on the manual editing. In this study, the map generalization methodology for automatic construction of multi-scale database from the primary data is proposed. Moreover, the generalization methodology is applied to the real map data and the prototype of multi-scale map dataset is generated. Among the generalization operators, selection/elimination, simplification and amalgamation/aggregation is applied in organized manner. The algorithm and parameters for generalization is determined experimentally considering T$\ddot{o}$pfer's radical law, minimum drawable object of map and visual aspect. The target scale level is five(1:1,000, 1:5,000, 1:25,000, 1:100,000, 1:500,000) and for the target data, new address data and digital topographic map is used.

Ajax(Asynchronous JavaScript and XML)를 이용한 표준 기반의 웹 응용프로그램 개발로 플러그인(Plug-In) 방식의 비표준 웹이 특정 브라우저에 종속적이지 않은 환경으로 변화하였다. 그러나 Ajax 타일지도는 몇 가지 한계점이 있으며 이러한 문제를 해결하기 위해서 본 논문에서는 새로운 HTML5 표준과 인코딩 된 data-URL을 이용하여 레스터웹 지도 서비스에 활용될 수 있는 공간정보 전송 및 저장기법을 제안한다.

LBS(Location Based Service) and GIS (Geographic Information System) are supporting necessary services for system which provides geographic information using location information based on various platforms. However the mobile computing environments such as PDA system have serious limitations in functional viewpoints compare of general computing environments, it has problems for developing GIS system which is providing various information. In this paper, we suggest the reduced methods of digital map and format of web-linked digital mao in order to fit in mobile environment. As a result of map generation, the total capacity of the supported digital map was diminished about $99.34\%$ than the original map.

There has been a lively discussion on improving Korean students' academic achievement and the imbalance in their recognition of the value of mathematics. In this context, there is a need for a program that enables the majority students who regards mathematics as a subject for the entrance examination to recognize the practicality and historicity of mathematics. Educational books on mathematics in everyday life or the history of mathematics are also expected to serve as an effective tool. In addition, Web 2.0 Map is another means of representing mathematics in everyday life and the history of mathematics in connection with the practical context. The active storytelling process in which mathematics in the practical context in mathematical educational books is represented in Web 2.0 Map is expected to help to understand in depth the practicality and historicity of mathematics. Nevertheless, mathematical educational books and Web 2.0 Map may lead to a considerable variety of outcomes and speeds if carrying out tasks depending on the student's competence and may have practical difficulties in being operated in class. These concerns, however, can be resolved through the creative activity programs adopted in conformance with the 2009 revised curriculum. Therefore, this study intends to develop a program for creating mathematical story maps through mathematical educational books and the Mashup of Web 2.0 Map in accordance with the process of developing activity programs. This study also intends to determine its effectiveness in enabling students to recognize the practical and historical values of mathematics.

In this paper I try to analyze the trends of f environments, which changes dramatically, on the center of Web2.0 and Geospatial web, and then investigate how these new technologies can be applied in the field of geography. Nowadays international IT companies have provided the internee map which includes whole world. Also, mashup technology based on internet map has also been applied in the various areas. In the study of geography one can utilize the internet map as a basic data for regional study. In addition, I recognize that the collaborative intellectual of the ordinary people as well as expert can be utilized actively in the regional study. But in Korea, the mashup technology based on the internet map is not fully utilized. It is necessary to study the technologies related to the Geospatial web. For example, the study of the Geocoding technology which can locate the user information on the internet map, the technology that can combine the information of Geospatial attributes among the various information widely dispersed over the internet with the internet map, and the technology that can efficiently visualizing data by using wet-based vector graphic etc, is needed.

컴퓨터 기술의 발전과 네트워크의 급속한 확산으로 사회전반에 걸쳐 특허, 기업뿐 아니라 교육 현장의 효율화를 지원하기 위한 분야에서도 웹이 응용되고 있다. 교육 현장에서 작성되어지고 있는 문서 중 학습 지도안 작성은 교육 정보의 체계적인 제공이 미흡하고, 많은 시간과 노력이 요구되는 활동이므로 교수 개인이 모든 교수 활동에 필요한 지도안을 작성하는데는 어려움이 있다. 이를 위해, 웹에서 정보를 공유하여 문서의 재사용성을 높일 수 있는 시스템이 필요하게 되었다. 웹에서 표준화된 XML을 이용하여 문서의 생성과 검색, 그리고 재사용이 가능하도록 제공함으로써 교수자의 다양한 요구사항을 융통성 있게 수용할 수 있다. 본 논문에서는 학습지도안 시스템을 분석하여 공통DTD(Document Type Definition)를 생성하고 공통 DTD를 통해 표준화된 XML 문서를 제공한다. 좀더 효율적인 수업을 위해 학습지도안 작성이 용이하도록 학습지도안 작성용 에디터를 제공하며, 또한 XML DOM(Document Object Model)을 이용하여 검색기에서는 구조기반, 패싯, 키워드 검색 방법을 제시하고, 등록기에서는 DOM을 이용하여 해당 데이터를 추출하고 DB에 등록한다. 이는 문서의 재사용성을 높일 수 있다. 따라서, XML을 학교 현장에서 이용함으로써 웹에서 정보의 공유를 원활히 하고, 문서 작성의 효율성을 높이고자 한다.

The knowledge discovery from web has been studied in many researches. There are some difficulties using web log for training data on efficient information predictive models. In this paper, we studied on the method to eliminate sparseness from web log data and to perform web user clustering. Using missing value imputation by Bayesian inference of MCMC, the sparseness of web data is removed. And web user clustering is performed using self organizing maps based on 3-D plot by principal component. Finally, using KDD Cup data, our experimental results were shown the problem solving process and the performance evaluation.
