Recently, a few studies on context information have been focused to collect phenomena data like a temperature and a humidity in indoor environments. The importance of the former is increasingly recognized with changing environments and increase of heat stress in building. In this paper we present an indoor comfort index framework based on GIS for supporting context information instead of phenomena data in environments. We also present method for supporting comfort index and context information based on GIS in outdoor environments.

GIS is the tool widely used for the practical solution of spatial problems in every region regardless of the language and ideology. In this paper research trends and tendencies of GIS in North Korea are reviewed compared with those in South Korea. For this purpose, academic publications on GIS in North Korea are surveyed and classified according to main subjects in GIS. Such classification by main subjects of GIS in North Korea are conducted on the basis of the classification of research trends and tendencies of GIS in South Korea. As a result, researches in North Korea are mainly focused upon such fields as geodetic surveying and measurement, map manufacture, atmospheric phenomena, agriculture and disasters, while there are few studies related to such fields as national GIS policy and circulation, GIS education, internet-based GIS, and traffic, to name but a few. Most parts of applied data are based on low and medium resolution image such as meteorological satellite images, Landsat images, and so on. This reflects the low level of the development of GIS DB infrastructure in North Korea.

To meet the interoperability requirements associated with geospatial data access and geoprocessing, much efforts to design prototypical systems conforming to $OpenGIS^{TM}$ specification has been made. With respect to Object Web GIS, however, current internet mapping technology mainly focuses on either developing mapping libraries or client applications regardless of the future needs for interoperability such as an integration of $OpenGIS^{TM}$ standard for CORBA. In this paper, we propose an $OpenGIS^{TM}$ compliant mapping kernel. OpenViews, which is designed to meet those requirements. The kernel of OpenViews encapsulates the process of acquiring geospatial data in the format of $OpenGIS^{TM}$ Geometry through ORB(Object Request Broker). OpenViews, being designed based on well-known design patterns, is a highly extensible in that programmers can easily customize it on the object oriented architecture. The components implemented in OpenViews are CORBA/Java objects, and as such are portable and scalable in a networked environment. A companion package, OpenBroker, is also developed as a portable geoprocessing application server to facilitate the implementation and configuration of server side CORBA objects. It can be used for implementing objects for spatial analysis service which would be independent of legacy spatial database systems in many cases. OpenViews, together with OpenBroker, has been successfully prototyped using the technologies including EJB and servlet as the core components of an Open GIS compliant internet mapping.

Mobile internet service based on CDMA network evolution and multifunction mobile terminal is popular in Korea. Mobile internet service is classified as the information service using browser and mobile multimedia service using download platform. Killer applications based on multifunction mobile terminals have been developed for new business in mobile internet services. One of killer applications is location based seurvice (LBS) using mobile location information. In this paper, we develop mobile map browser using WIPI platform that is the main function in LBS. Mobile map browser interworking with GIS server provides the map information. The developed mobile map browser can be working on PDA and telematics terminals when WIPI is porting on these devices.

The Geographic Information System (GIS) is a system that collects, stores, analyzes and processes geographic object data existing in space. The GIS is widely used in application fields related to geography such as city planning, land-register management, forest resources management, etc. The importance and necessity of the GIS have been well demonstrated, and therefore many studies on this system have been carried out. However, most of those studies have just treated geographic information as spatial information, but have not considered or have overlooked changes of spatial data dependent on time. For example, transportation information management and atmospheric phenomena forecast, have not exactly reflected the actual world which changes with the flow of time. In this thesis, a temporal GIS is established to effectively and precisely process information on space objects changing with time and a database is built up in reference to changes in water temperature and salinity. And the isotherm and isohaline forecast system implemented to support graphical tool.

Lately, much researches for information management of web GIS base are gone. Specially, disaster Information Management System development of Web-Based for management and offer of disaster information such as flood or earthquake is necessarily necessary for prevention and countermeasure about disaster, disaster information acquisition of interest area. Spatial DB access for plan/analysis/management business of this system should be possible and must become display of disaster information and disaster mapmaking through internet for disaster prevention but research of web GIS base about this field is childhood yet. This research executed research for disaster information offer using HTML and Javascript and ESRI's ArcIMS that is development tools or web GIS. And this research could search disaster information of interest area through various kinds function and offer in display through user selection. Also, topography of interest area could confirm through third dimension topography model who use VRML. And this research could supply disaster information of Chunchon city using various function thorough system of Web-Based.

From the perspective of client-oriented administration, the study introduces the basic structure of Urban Inormation System (UIS) and examines problems and new strategies of UIS in Korean local governments. The study selects five metropolitan cities for a case study. According to this case study, UIS in Korea are focused on AM/FM and internally used only by practitioners. No government surveyed what their citizens want to get from UIS. To solve these problems, the study proposes developing strategies for client-oriented UIS as follows. First, local governments could use policy delphi technique to sum up the citizens' needs on UIS. Second, they need to pay more attention to the diversity and transmutability of administration zone and consider the importance of the connection between administration zone and attribute data collected on them. Third, UIS needs to keep a balance between AM/FM and living GIS. Fourth, internet UIS needs to be constructed which enables citizens' access to UIS more easily. Finally, GIS education and client-oriented administrative education need to be combined to improve government employees' mind for UIS.

It is noted that the paper mapping system for University Building Facility has many limitations in terms of data maintenance, real-time GIS data acquisition, and economic efficiency. The aim of this research was to evaluate an operational potential of an on site real-time mobile GIS technique to resolve the problem faced in the university. The idea is based upon the recent trends in the field of 'Telecommunication and Information Technology' that uses a PDA (personal Digital Assistants), wireless network computing, mobile computing, etc. A real time mobile GIS approach has been adopted, in which a PDA is linked to a wireless internet and field workers record data on the computer at the site and analyse data on site. While there should be a considerable number and variety of factors associated with real-time mobile GIS quality, this research focuses on three criteria that are identified as fundamental to customer requirements; (1) data quarry (2) spatial analysis (3) real-time GIS database building. 'Art--empirical study for a case study facility has been conducted to confirm the validity for the system. The system has been checked experimentally, enabled the field users to quarry the data required simply and execute spatial analysis (buffer, overlay etc.,) accommodating versatile alternatives on the site. Detailed visual maps can be generated over large areas quickly and easily. The PDA interface, in particular, were ideally suited for field users to interactively displaying positional information with attribute data. This system has shown to be quite convenient to maintaining a highly reliable database since it could playa crucial role in documenting at real-time basis temporal and spatial changes occurred in the facilities. It is anticipated that this research output will greatly serve to introduce the reliable and cost-effective facility mapping system in the university by overcoming serious constraints suffered from the past non-real time mobile GIS approach.
