If the existing real-time systems are integrated based on SOA, real-time SOA should be developed. Generally, in real-time SOA a service can be divided into several small services and their estimated execution time is given by provider systems. However, an estimation, which analyzes time elements related to transmit and receive messages among requesters and providers, is needed. In order to enhance QoS of Web service, this paper proposes enhanced worst-case execution time estimation by considering WS-transaction and common use of multi-processors system.

In this paper, we implement the speech recognition system based on the continuous distribution HMM and Browser-embedded model using the Java. That is developed for the speech analysis, processing and recognition on the Web. Client sends server through the socket to the speech informations that extracting of end-point detection, MFCC, energy and delta coefficients using the Java Applet. The sewer consists of the HMM recognizer and trained DB which recognizes the speech and display the recognized text back to the client. Because of speech recognition system using the java is high error rate, the platform is independent of system on the network. But the meaning of implemented system is merged into multi-media parts and shows new information and communication service possibility in the future.

In this paper, we propose the hybrid lighting control system on multiple sensor. The proposed hybrid lighting control system was designed for management and control of street lightings by configured as the data display part of integration-interworking part, the data conversion-processing part of integrated management part, and the communication part of gateway system. The data are implemented to designing the DB to enable to storage in real-time by enable to monitoring by wireless remote control and schedule set. As a result of the efficiency verification of the proposed hybrid lighting control system, the hybrid lighting control system be to the real-time monitoring and remote lighting control was possible, because to peristalsis with smart devices and portable PC etc., and it could be obtained the effect of energy and electricity, communication cost reduction.

기업 내부 및 외부 환경 요인 분석을 통한 올바른 비즈니스 전략 수립은 기업의 최상의 결과 창출로 이어질 수 있다. 때문에 SWOT(Strength, Weakness, Opportunity, Threat) 분석을 통해 기업 내부의 강점요인과 약점요인을 인지하고, 기업 외부의 기회요인과 위협요인을 정확하게 분석하는 과정은 매우 중요하다. 그러나 많은 기업들이 그들의 상대적인 강점요인과 약점요인, 기회요인과 위협요인에 대해 정확하게 판단하지 못하는 경우가 많다. 본 연구는 기업이 환경분석 과정에서 보편적으로 활용하는 분석모델 중 하나인 SWOT 분석을 지원하는 도구를 설계 및 구현한 것으로, 각 분야의 전문가들이 작성한 SWOT 분석 결과를 바탕으로 SWOT 분석 사례 DB를 만들어 사용자가 데이터베이스에 저장되어있는 각각의 환경요소를 조회하여 기업에 적합한 환경요소들을 선택, 수정, 추가하게 함으로써 SWOT 분석 시에 기업들이 고려해야하는 내부 및 외부 환경 요인에 대한 정보를 제공하고자 한다. 이를 통해 기업들이 자신의 내부 역량에 대해 보다 정확하게 인지하고, 외부 환경 변화에 대한 고찰을 도울 수 있을 것으로 사료된다.

요즈음 우리가 살고 있는 시대를 정보화 사회라고 말한다. 기업과 공공기관, 학교, 가전제품은 물론 개인의 업무에 이르기까지 인터넷으로 연결된 컴퓨터를 이용하여 업무를 신속히 처리하고 있다. 이와 같은 인터넷이 발달된 시대의 무한 경쟁사회에서 앞서 나아가기 위해서는 관련 정보를 빠르게 얻고 업무에 쉽게 적용할 수 있어야 한다. 이와 같이 필요한 정보를 신속히 찾고 관련정보를 이용하기 위해서는 인터넷을 이용하는 것이 가장 빠를 수 있다. 인터넷은 방대한 자료의 바다로 연결되고 사용자와 사용자는 물론 사용자와 기업까지도 직접 연결해줄 수 있으므로 필요한 정보를 찾고 정보를 교환하고 문제를 해결하고 정보를 제공할 수 있는 최선의 방법이라고 볼 수 있다. 본 논문에서는 인터넷을 통한 데이터베이스의 정보를 공유하는 방법을 제시하고 웹 서비스 프로그램을 통하여 그 과정과 구현 결과를 보이려고 한다. 대부분의 웹 프로그램에서 제공하는 데이터는 다양한 포맷으로서 일방적으로서 제공되는 방식이므로 사용자가 파일로 저장하기가 매우 불편하고, 필요한 자료만을 선택하여 가져가거나, 가지고 있는 자료를 제공하고자 할 때 어려움이 있었다. 이러한 문제점을 해결하기 위하여 웹 서비스 기술을 이용하여 서로 쉽게 공유할 수 있는 데이터베이스 시스템을 구현하고자 한다.

Electronic commerce is widely used with the development of information communication technologies in internet using public key certificates. And the study for access control in Web application and DB system is also progressed actively. There are many verification method for PKC(Public Key Certificates), which are CRL, OCSP, SCVP and others. But their certificates verification methods for PKC cannot to be applied to PMI(Privilege Management Infrastructure) which is using AC(Attribute certificates) because of synchronization of PKC and AC. It is because AC has no public key, AC Verifier must get the PKC and verify the validity on PKC and AC. So in this paper we proposed the new AC-based certificate verification model. which provide the synchronization in two certificates(AC and PKC).

In order to achieve an efficient urban regeneration of the nation, it is required to determine the extent of decline nation-wide and the declined areas for each district and also to evaluate the potentials of the concerned areas. For this task to be accomplished, a construction of a comprehensive diagnostic system based on spatial information considering diversity and complexity is required. In this study, a total information system architecture for urban regeneration is designed as part of the construction of such a diagnostic system. In order to develop the system, a city and district level unit decline diagnostic indicators has been constructed and a decline diagnostic system has been developed. Also, a scheme to promote the advancement of the system is proposed. The DB construction is based on the city and district level nation-wide and metadata for the concerned level is constructed as well. The system is based on the Open API and designed to be flexible for extension. Also, an RIA-based intuitive UI has been implemented. Main features of the system consist of the management of the indicators, diagnostic analysis (city and district level decline diagnosis), related information, etc. As for methods for the advancement, an information model in consideration of the spation relations of the urban regeneration DB has been designed and application methods of semantic webs. Also, for improvement methods for district unit analytical model, district level analysis models, GIS based spatial analysis platforms and linked utiliation of KOPSS analysis modules are suggested. A use of a total information system for urban regeneration is anticipated to facilitate concerned policy making through the identification of the status of city declines to identify and the understanding of the demands for regeneration.

A Web database System is a large-scaled multimedia application system that has multimedia processing facilities and cooperates with relational/Object-Oriented DBMS. Conventional hypertext modeling methods and DB gateway have limitations for Web database because of their restricted versatile presentation abilities and inefficient concurrency control caused by bottleneck in cooperation processing. Thus, we suggest a Dynamic Navigation Model & Virtual Graph Structure. The Dynamic Navigation Model supports implicit query processing and dynamic creation of navigation spaces, and introduce node-link creation rule considering navigation styles. We propose a mapping methodology between the suggested hypertext model and the relational data model, and suggest a dynamic allocation scheduling technique for query processing server based on weighted value. We show that the proposed technique enhances the retrieval performance of Web database systems in processing complex queries concurrently.
