This research proposes an on-line Environmental Information System for Planners (EISP). The Environmental Information System for Planners has been developed in collaboration with five local authorities as a web-based system designed to support decision making within the UK planning framework. It has been built as a ‘proof-of-concept’ system to demonstrate the value to urban planning of making information on environmental issues more widely accessible. The EISP has been designed to support three principal planning functions carried out by Local Authorities: Pre-planning enquiries; Development control decisions; and Strategic planning. The system incorporates 12 environmental themes: Air quality (PM10); Shallow undermining; Landslide susceptibility; Groundwater protection; Flood risk; Drainage; Land contamination; Proximity to landfill; Biodiversity; Natural heritage designations; Man-made heritage; and Natural Ground Stability (Geohazards). The design framework is based upon a series of decision flow diagrams, each covering one of the above themes. These decision flows take account of current planning procedures in the UK. Industry-standard web technologies have been employed to integrate the flows and develop the functionality that will allow the planner access to the system through secure web pages. Underpinning the system is an environmental Geographical Information System (GIS) that contains the most up-to-date data, information and models relevant to each of the environmental themes listed. The planning regulations are subject to change and so the system has been designed in a modular way so that new legislation can be accommodated without the need for a complete system rewrite. This modular approach also means that the system can be readily adapted to reflect local priorities and to draw on local datasets. The EISP was successfully tested and the thesis concludes with a costed business case study for commercial implementation and rollout of a production EISP system populated with appropriate environmental data within UK local authorities.

The main purpose of this research is to incorporate additional higher-level semantics into the existing data replication strategies in such a way that their flexibility and performance can be improved in favour of both data providers and consumers. The resulting approach from this research is referred to as the selective data replication system. With this system, the data that has been updated by a data provider is captured and batched into messages known as update notifications. Once update notifications are received by data consumers, they are used to evaluate so-called update policies, which are specified by data consumers containing details on when data replications need to occur and what data needs to be updated during the replications.

Mobile Geographical Information Systems are becoming a more and more important tool for presenting geographical data. They are used to support decision making processes, present an overview of distributed information or are in a form of location based services. The problem lies in the fact that mobile devices have limited resources and should still be able to present massive amounts of content. Ideally, the user and the conditions in which the program runs are well defined, but this is usually not the case. This thesis provides a sample prototype implementation of a mobile GIS developed as an alternative to an existing web-based user interface (UI). It focuses on specific conditions present on mobile devices, ways of presenting the data and possibilities of reusing existing elements from the web UI that could be suitable for the mobile environment.

Tunas are the ocean highly migratory species, Taiwan is the top countries of the tropical tunas fishery in the Indian Ocean, and the tropical tunas are the main target species of our country in Indian Ocean. There were no systematic arrangement of large-scale tuna longline fishery in the past. While assessing the resource assessment, there are only few information included and discussed .The Purpose of this research based on the large-scale fishing vessels¡¦ logbooks, and analyzed the catch, CPUE and fishing effort of tropical tuna longline vessels with geographical information system. Discuss the dynamic patterns of tropical tuna vessels, and try to research the factors influencing the vessels activities. The research focus on the whole Indian Ocean, and utilizes the geographical information system to analyze and research CPUE from 1970 to 2007(38 years) with annual tropical tuna catch. Then, select the steady times of the fishery activities from 1999 to 2003 and carry on the analysis of catch data. Second, choose the first 20 fishing vessels of annual Yellow-fin tunas and Big-eye tunas with largest catch in this period, regard these as the representative researching vessels. According to the navigation route of each vessel, the results of the analysis are derived: 4 patterns of Yellow-fin tuna, 3 patterns of Big-eye tuna. On the whole, there are 5 routes of Taiwan fishing boat of tuna longline fishing vessels in the Indian Ocean: 1. The fishing vessels go back to the equator across Arabian Sea from the equator. 2. The fishing vessels go back to the equator across southern Indian Ocean from Arabian Sea. 3. The fishing vessels go back to the equator across the Bay of Bengal from the equator. 4. The fishing vessels go back to the equator across the southern Indian Ocean from the equator and stay near the equator during the whole year. Finally, conclude that tuna longline fishery of Taiwan target tropical tunas in the Indian Ocean are dominated by factors such as international fish price, climate, walrus and the relationship with fishery cooperative countries, etc.. These factors lead to the 5 kinds of vessel dynamic ways in the Indian Ocean.

Perceptual dialectology studies have shown that people have strong opinions about the number and placement of dialect regions. There has been relatively little research conducted in this area on Korean, however, with early studies using only short language attitude surveys. To address this gap in research, in the present study, I use the 'draw-­?a-­?map' task to examine perceptions of language variation in Korea. I ask respondents to draw a line around places in Korea where people speak differently and provide names, examples, and comments about the language spoken in those areas. With the resulting data, I use ArcGIS 10.0 software to quantitatively identify, aggregate, and map the most salient dialect areas and categories for subjects' perceptions. I also perform a content analysis of the qualitative data provided by respondents using 'keywords.' During this process, I categorize comments and labels given by respondents to find emerging themes. Finally, I stratify perceptions of respondents by demographic factors, e.g., age, sex, and urbanicity, that have often been found to be important in language variation and change. An analysis of these data suggests that Koreans' perceptions of dialect regions are not necessarily limited by administrative boundaries. In fact, the data reveal not only perceptions of dialect variation unassociated with geographic borders, but they also tap into the way people connect ideas about language and place. Results from this study have implications for language attitudes research, perceptual dialectology methodology, and the relationship between language and place in Korea.
