Abstract:
A system and a method for discovering a web service based on an intelligent agent platform are provided to enable a user to use the desired service by enabling an agent to provide discovery for a UDDI(Universal Description, Discovery, and Integration) registry and an execution result of an e-business web service. An input part inputs a keyword to a UDDI client agent(10-1) included in the agent platform. A requestor requests service search to a UDDI server from the UDDI client agent by using the keyword. A receiver enables the UDDI client agent to receive a WSDL(Web Service Description Language) result from the UDDI server as a search result. A display part displays a web service execution result by enabling the UDDI client agent to analyze a received WSDL list and generate lists as many as the search result. A tool enables a user to input a personal key value and the keyword by enabling the UDDI client agent to make an API(Application Program Interface) to access the e-business service into an agent.

PURPOSE: A natural lighting system using an intelligent recognition reflection mirror is provided to appropriately irradiate sunlight to each floor regardless of distance between a sunlight irradiating part and a reflection mirror. CONSTITUTION: A natural lighting system using an intelligent recognition reflection mirror comprises a sun tracking reflector(1), rotary reflection mirrors(3a,3b,3c,3d), and reflection mirror driving units(4a,4b,4c,4d). The sun tracking reflector is installed above a building and reflects sunlight by tracking movement of the sun. The rotary reflection mirrors are installed outside of the each floor and reflects sunlight irradiated from the sun tracking reflector to each floor.

PURPOSE: Optical fiber for high efficiency light concentration and a manufacturing method thereof are provided to prevent light loss by minimizing an air gap when forming an optical fiber bundle, thereby improving light combination efficiency. CONSTITUTION: An optical inducing portion(A) forms a cross section as rectangular or regular hexagon shape. The optical inducing portion is comprised of a core and a clad. The length of the optical inducing portion is 2 to 12cm. The core is comprised of quartz or poly-methyl-methacrylate. The clad is comprised of a plastic resin. A light guiding portion(B) is connected to the optical inducing portion and guides light. A plurality of optical fibers(10) for high efficiency light concentration forms an optical fiber bundle.
Abstract:
PURPOSE: A floating wind power generator is provided to prevent a manager from falling down to the sea by preventing a floating structure from shaking. CONSTITUTION: A floating wind power generator comprises a generator housing, multiple blades, a floating body(220), a receiving unit, and a structure support(210), and a supporter(230). The blades are rotatably installed in the generator housing. The floating body has a hollow. The receiving unit accepts air to generate additional buoyancy when seawater flows into the hollow. The structure support is located at the top surface of the floating body. The supporter is coupled to the bottom surface of the floating body.

Abstract:
An adaptive discovery system based on a priority on an ad-hoc network and an adaptive discovery method are provided to dynamically regulate a caching strategy, a service period, and a network packet processing process by applying the priority on a network service based on popularity of the network service. An LSD(Lightweight Service Discovery) engine includes an application layer(100), a service management layer(200), and a network communication layer(300). The application layer provides an application for providing a ubiquitous service. At the service management layer, the LSD includes two main modules having a cache manager and a policy manager. The network communication layer includes a UDP(User Datagram Protocol)-based multicast module, a TCP(Transfer Control Protocol)-based unicast module, an HTTP(Hypertext Transfer Protocol) module, and an SOAP(Simple Object Access Protocol) module. A service discovery process is performed by using an XML(eXtensible Markup Language) structure.
Abstract:
An agent-based service discovery system, a service discovery method, and a recording medium storing the same are provided to offer more diversified services to users by creating discovery agents according to each service discovery protocol and to develop a new agent at a low cost by providing an API(Application Programming Interface) using a JADE(Java Agent DEvelopment Framework) agent platform. A JADE agent platform(10) in a discovery agent system comprises a discovery agent(110), an AMS(Agent Management System) agent(120), a DF agent(130), and a user agent(150). The discovery agent(110) converts the messages transmitted from different service discovery protocols and the messages used in the JADE agent platform(10) bidirectionally so that other agents in the JADE agent platform(10) can use them. The AMS agent(120) executes a management and monitoring function for other agents, and has a control right for the life cycles of agents. The DF agent(130) serves as a yellow page that stores the service lists received to the JADE agent platform(10). The user agent(150) interrogates to the DF agent(130) and executes as proxy so that a user can use a desired service.
