With the rapid development of information and telecommunication technologies, the adoption of ubiquitous technologies is increasing for the realization of new effective u-City services. u-City is defined as a next-generation informatization city that can innovate a city's various functions, such as improving the welfare of the citizenry, ensuring safety based on systematic urban management, improving the quality of lives, and increasing convenience in city life, by merging cuttingedge information and telecommunication infrastructures and ubiquitous information services with urban space. There is therefore a need to recognize that a successful u-City implementation strategy involves developing the previous UIS into a ubiquitous technology-based UIS and integrating UIS's various urban informations with effective u-City services. In this paper, for UIS-based u-City implementation, the intelligent integration model of urban spatial information based on interoperability is proposed.

향후 u-City의 지능화된 도시시설물 관리를 위해서는 상세한 서비스모델 및 시나리오의 구현이 필요하다. u-City에서는 각종 센싱데이터를 실시간으로 전송받아 모니터링하고 이벤트 상황을 인식하며, 공간정보를 기반으로 분석 및 처리, 결과가 제공되어지는 능동형 도시시설물관리시스템으로 변화될 것이다. 이러한 관리시스템은 기존의 DB관리 중심의 UIS(도시정보시스템)와는 차별화된 차세대 시스템으로, 본 연구에서는 이러한 시스템에서 제공되어질 서비스 시나리오 중 공동구관리 시나리오를 개발하여 관련 시스템 설계 및 개발에 활용할 수 있는 기반을 마련하였다.

The management model for ground urban facilities based on Ubiquitous technology is proposed to support the u-City projects going on domestically and, reinforce the nation's competitiveness. This research is a part of the Intelligent Urban Facility Management project of the Korean Land Spatialization Group (KGSL). First, this study started from the investigation of existing u-City businesses in order to drive essential components and considerations for the urban facilities management system. Considering the driven conclusions, this study finally proposed the adequate management model of urban facilities for the newest urban environment, u-City.

The ultimate purpose of cities is 'the enhancement of quality of life in city'. In order to achieve this, it is required to optimize the Ontology-driven ubiquitous services included in the U-City and UIS of regions and communities and so on. Almost U-Service's contents are related to spatial or temporal extent. So it is important to design Spatio-temporal event schema for efficient access to U-City. There is a rapid change into an urban society in the shape of Ontology-driven ubiquitous services in which a content on a region or an incident is newly reconstructed through various ideas with the influence of the ubiquitous environment.

This study surveyed the variables associated with tailored user interfaces (UIs) to identify and apply to. healthcare web services. A total of 308 elderly people of age 50 and above), living in Incheon, South Korea, were surveyed through one-on-one interviews. The survey results of these 300 subjects were analyzed and used to demonstrate that younger subjects higher EQ-5D and TAM indices. The technology acceptance model showed the greatest effect on the perceived need for web services.

Garlic from 4 main growing area was analyzed for the composition related to garlic flavor. Twenty-eight volatile compounds in garlic were separated by GC and twenty five were identified by GC/MS. Total peak area was high in garlic from $S\u{o}san$, and low from $Hampy\u{o}ng$. However, no significant difference was found in total peak area of sulfur compounds for garlic from Namhae, $S\u{o}san$, and $Uis\u{o}ng$. The results of free sugars analysis showed that relatively large amount of 1-kestose, 1-nystose, and 1-F-fructosyl nystose known as fructooligosaccharide were found in garlic in addition to glucose, fructose, and sucrose. Garlic from $S\u{o}san$ contained high amount of 1-nystose and 1-F- fructosyl nystose. Total free amino acid content in garlic was in a range of $2036.1{\sim}2704.0mg%$, and it was higher in garlic from $S\u{o}san$ and $Uis\u{o}ng$. Lactic acid, pyruvic acid, oxalic acid, malonic acid, fumaric acid, levunic acid, succinic acid, malic acid, citric acid and pyroglutamic acid were found in garlic. Total organic acid content in garlic was $1905.7{\sim}2359.2mg$, and garlic from $Hampy\u{o}ng$ had relatively low organic acid contents.

TV businesses that have brought a competitive structure in terms of price, definition, product design for a long time now are bringing User eXperience (UX) into relief as DTVs come to support broadcast information-related services such as various broadcast channels and Electronic Program Guide(EPG), etc., and playing of multimedia contents like music/videos, etc. This study worked on an evaluation by developing a UI to control easily the various and complex broadcast contents or multimedia contents provided by DTVs. The UI Design for new DTVs was developed based on Function, Flow and Form in the concept of Single ABC (Access, Browser and Control), and the usability test of the developed UI concept along with the UIs of the major DTV products, was done for Channel Managers and the multimedia browsers for 32 users of DTVs in the U.K./U.S., respectively. As a result of the usability test, the new concept of Channel Manager was evaluated high both in the U.K./U.S, while the multimedia browser was evaluated low in the U.S., relatively.

The purpose of this paper is to analyze the activation methods of GIS industries through GIS industry current issue analysis in Korea to provide as following. First of an in order to analyse current GIS industries, there are three divisions as follows: existing GIS industry, new technology GIS industry, and commercial GIS industry. The existing GIS industry includes survey industry, municipality UIS and remote sensing. The new technology GIS industry has telematics industry, LiDAR industry, ubiquitous industry, LBS industry, internet, and u-city industry. The commercial GIS industry consists of civilian request GIS industry and spacial data distribution industry. The national geographic information industry contains problems and directions of the 1st, 2nd NGIS and 3rd NGIS plan direction policy. These classified GIS industries present various problems of policies and invaluable results for the future GIS industry activation directions as follows: Presence of the GIS contents technologies win be the most important core for the GIS industry activation related to IT839 policy of the government in Korea.
