This paper reviewed the main characteristics of Web 2.0 and discussed the possible applications related to National Geographic Information Systems. In general, Web 2.0 refers to a next generation World Wide Web environment that let people participate and share information and data. The recent examples using Web 2.0 with geo-spatial information are convincing us apply Web 2.0 into National Geographic Information Systems. In order to imply Web 2.0 into National Geographic Information Systems, we should consider not only technological advancements related to providing the services but also shifting the relationship between information provider(government agencies) and end-users. In other words, new platform should be provided to users so that users can easily create, share, and mash-up data, which was previously managed and owned only by government agencies. Successful integration Web 2.0 platform into National Geographic Information Systems require some important points such that; 1) the consideration for the data should be changed from closed and agency owned data to opened and shared data. 2) data standards should be established to integrate all data from different sources. 3) real change need to be happened rather than different naming on the same system.

One of ways for effectively maintaining asbestos buildings is to select asbestos buildings to be removed firstly by manufacturing and analyzing asbestos map of various topics. Thus, in this study we manufactured asbestos map of various topics for the effective management of asbestos buildings owned by Seoul using QGIS (Quantum Geographic Information System). To select asbestos buildings likely to cause asbestos scattering problem and exposure into the air, we comprehensively took into consideration various topics such as asbestos buildings density, asbestos-area ratio, asbestos buildings distribution considering the population, first removal object, risk assessment, elapsed year. As described in this study, using the GIS may be utilized as a method for selecting asbestos buildings to be removed firstly as well as distribution of asbestos buildings. In the future, it is necessary to make assessment criteria considering diversification of property value in GIS such as the characteristics of the living environment around the asbestos buildings. This is expected to be utilized to manage the vulnerable region to asbestos exposure.

Environmental Impact Assessment(EIA) in Korea has developed as a tool for environmental conservation and decision making since Environmental Impact Statement(EIS) preparation in 1981. For effective implementation of it, we do system development and method enhancement continuously. The recently introduced GIS (Geographic Information System) can integrate geographic and attribute data, which will be applied to scoping, assessment, and alternative assessment, etc. in EIA. This study has three major components. First, it explains building of EIA factors of natural environment, living environment, and socio-economic environment of the study area defined in EIS preparation regulation. Second, the study presents applications of assessment method concerning suitability analysis of landfill site using GIS. Finally, it shows integration of GIS and odor impact assessment. Based on these analysis, the study makes some recommendations and conclusions.

This study was designed to examine the influence of social-environment factors on high risk alcohol consumption. The study analyzed 229 local areas throughout Korea. Main variables included high risk alcohol consumption and environment factors such as population structure, liquor stores. For exploring the problem drinking, geographically weighted regression(GWR) using the geographic information system(GIS) was utilized to analysis. Major findings are rate of perceived stress, number of restaurants and bars. Especially problem drinking were influenced restaurants and bars, and the form or aim of restaurants and bars had differentiability to the problem drinking. These results have implication about the regulation policy of alcohol availability for prevention of alcohol related problems.

This paper aims to develop a conceptual framework for evaluating the impact of factors influencing the decision of Vietnamese students to study English in the Philippines. The empirical analysis used data from the survey data of 318 respondents living in Vietnam. Comprehensive, valid, and reliable tools (SPSS 26 software) are used to analyze and verify the gathered data, and the hypotheses developed. The results identified the factors that affect the decision of Vietnamese students to study English in the Philippines include knowledge and awareness, personality recommendation, cost issues, environment, geographic proximity, and social link. Based on the overall findings of this study, several implications are presented for educational practices in academies and schools about English teaching in the Philippines. To increase the ability to get students to study English in the country, it is important that schools or academies must understand the demands of students regarding the academic environment, and in particular, to know what factors determine the decision from the customers' point of view. This study contributes significantly to the understanding of agencies and educational managers about the student's choice behavior in the context of the need to improve foreign languages and, thus, help improve the competitiveness of agencies and English schools.

In this study, GNLP(GIS linked non-linear network analysis program) for pipeline system analysis has been developed. This GNLP gets the input data for pipeline analysis from existing GIS(geographic information system) data automatically, and has GUI(graphic user interface) for user. Non-Linear Method was used for hydraulic analysis of pipe network based on Hazen-Williams equation, and Microsoft Access of relational database management system(RDBMS) was used for the framework of database applied program. GNLP system environment program was improved so that a pipe network designer can input information data for hydraulic analysis of pipeline system more easily than that of existing models. Furthermore this model generate output such as pressure and water quantities in the form of a table and a chart, and also produces output data in Excel file. This model is also able to display data effectively for analysed data confirmation and query function which is the core of GIS program.

In order to establish and promote geographic information activities in controled environment maximizing interoperability and the degree of reusability of geographic information resources scattered in distributed platforms, standardization is recognized as one of the basic solutions essentially being performed at the community level, where intends to align with international standards. This paper describes some technical aspects of standardization needed to build a systematic mechanism of national geographic information standards development, giving approach to conceptual analysis especially directed by ISO(International Organization for Standardization). Following some enumerated benefits for profile based national standard architecture and the brief review from canadian approach we suggest herein a overview of national and community level standardization framework, which identify its primary elements consisting of common basis for standard development mechanism based on profiles.

The King George Island, where the King Sejong Station is located, represents one of the gateways to the Antarctica from the point of its geographical aspect. It also serves as an advanced post, and plays an important role in the extending for Korea's Antarctic research activities. The existence of maps is not only a basic element for the constructing geographic informations supporting these activities, but also an implied way of announcing the sovereignty over the KingSejong Station in global world. However, the precise surveying for the geographic information has not been carried out, and thus topographical maps as well as geographic information assuring enough accuracy are still missed in this area. This fact had forced Korea to rely on using maps produced by foreign countries. Therefore, this study aims to generate digital topographical maps of 1: 5,000 scale for the constructing geographic information using lightweight aerial photogrammetry system first. And further, it will contribute to offer practical base data for the future research related to the Antarctic environment through the analysis of glacier retreat and change using this new digital map comparing with existing one.
