In accordance with the completion of the spatial database building works in the central and/or local government authorities as well as the rapid popularization of various information services through internet. it is heavily required to provide spatial information services through World Wide Web. To provide a qualified spatial information service. it is crucial to have a Web-based GIS (Geographic Information Service) service system equipped with the publicity. the convenient accessibility. and the easy-to-use user interface. In this paper. we introduce a new component system for Web-based spatial information services based on the OpenGIS Simple Feature specification for OLE/COM[3] and OLE DB specification[4]. The important functionality of a Web-based spatial information service system includes its accessibility of various existing GIS server system and huge databases in addition to the resolution of response-time delay problems caused by transmitting a large amount of digital maps via internet[6]. To cope with these problems. Our component system has been designed to access heterogeneous databases in transparent manner and to support vector-based and/or image-based image production techniques for shortening transmission time.

웹을 기반으로 하는 인터넷 정보서비스의 급속한 대중화와 더불어 지방자치단체 및 공공기관에서 공간정보 데이터베이스 구축작업이 완료됨에 따라 인터넷을 통한 공간정보 서비스 제공에 대하 새로운 요구가 발생하고 있다. 따라서 뛰어난 공유성, 간편한 접근성, 익숙한 사용자 인터페이스를 제공하는 웹을 이용한 GIS 서비스는 필수적이며, 본 논문은 이를 위한 개방형 GIS 및 컴포넌트 기술을 기반으로 하는 인터넷 기반의 공간정보 서비스를 위한 컴포넌트를 제안한다. 인터넷상에서 웹을 기반으로 하는 공간정보 서비스를 제공하기 위해서는 기존에 구축되어 있는 다양하고 방대한 GIS 서버 및 데이터를 이용할 수 있어야 하며, 방대한 양의 지도 데이터 전송으로 인한 응답시간 지연 문제를 해결해야 한다[6]. 이를 위해 논문에서는 Open GIS Simple Feature for OLE/COM 사양[3]과 OLE DB 사양[4]을 지원하는 데이터 제공자 컴포넌트를 제시하고 이를 기반으로 하여 이미지 기반 및 벡터 기반 이미지 생성 기법을 지원하는 인터넷 서비스 컴포넌트를 제시한다.

Even though driving under the influence of drug (DUID) is a worldwide problem, we, Korea has no regulation system yet except for alcohol, and there are little cases reported related to DUID. In order to investigate the type of abused drugs for drivers in Korea, we tried to analyze controlled and non-controlled drugs in alcohol-positive blood samples. 275 whole bloods, which were positive for alcohol on the roadside test, were collected from the police for two months ($Nov.{\sim}Dec.$ 2006). The analytical strategy was constituted of three steps: First, alcohol in blood samples were confirmed and quantified by gas chromatography. Second, controlled drugs were screened by $Evidence_{investigator}\;^{TM}$ (Randox, U.K.) as preliminary test. It was based on immunoassay by biochip array analyzer. Nine groups of drug abuse were screened: amphetamines, methamphetamines, cannabis, cocaine, opiates, barbiturates, methadone, benzodiazepines I (oxazepam) & II (lorazepam). Finally, confirmation of these drugs was performed by GC-MS. Blood samples were extracted by solid-phase extraction by $RapidTrace^{TM}$ (Zymark, U.S.A.). After trimethylsilyl (TMS) derivatization, eluates were analyzed to GC-MS. Total 49 drugs were investigated in this study including controlled drugs, antidepressants, 1st generation antihistamines, dextromethorphan, nalbuphine, ketamine, etc. For rapid detection, we developed the automated identification system. It was made up a new software, "DrugMan", modified Chemstation data analysis menu and newly developed macro modules. A series of peak selection, identification and reporting of the results were performed automatically by this system. Concentrations of alcohol in 275 blood samples were ranged from 0.011 to 0.249% (average, 0.119%). Among 149 blood samples, just six samples (4.0%) were showed positive results to the immunoassay: one methamphetamine and five benzodiazepines group I. By GC-MS confirmation, only benzodiazepines were detected and methamphetamine was not detected from immunoassay positive blood sample. Besides these drugs, 5 chlorpheniramines, dextromethorphan, diazepam, doxylamine, ibuprofen, lidocaine and topiramate were also detected in whole bloods by GC-MS. Conclusively, the frequency of drug abuse for Korean drivers was relatively low. There was none case which illegal drug was detected. However these results were limited to alcohol positive blood samples, so it is necessary to analyze more samples including alcohol negative blood.
