최근 청소년층의 인터넷 이용이 급격히 증가하면서, 초등학생 중 90% 이상이 인터넷을 이용하고 있으며, 그 연령대도 낮아져 저학년 어린이의 이용률이 지속적으로 높아지고 있다. 또한 청소년의 30%가 인터넷 중독 또는 중독 직전에 있는 것이 실태이기도 하다. 10대가 현재 가장 많이 사용하고 있는 정보매체인 컴퓨터는, 그것을 사용함에 있어 교육적으로 도움이 되는 면도 있지만 반면에 무분별한 인터넷 용어나 비속어의 사용, 무절제한 지속적인 이용, 유해사이트에의 노출 등 많은 문제가 산재해 있다. 기존의 유해사이트 차단과 컴퓨터 사용시간 제한 등의 사용 관리를 위한 프로그램들이 많이 선보여진 상태이지만 그 활용 면에서 보면, 좀 더 사용자의 특성을 이해하여 어른들보다 절제가 어려운 어린이 사용자를 위해 부모 혹은 선생님과 같은 관리자와 가르침의 역할을 해줄 수 있는 부분이 더욱 필요하다. 본 연구에서는 무형의 소프트웨어 프로그램이 사용자에게 명령을 내리고 그것을 수행하게 하는 것 보다, 사용자가 친숙하게 받아들이고 정서적으로 접근할 수 있는 사용자와 인터렉션이 가능한 캐릭터 형태의 물리적 아바타를 제안하고자 한다. 또한 비속어나 그와 비슷한 단어들을 사용할 시 의미적으로 비속어인지 아닌지 아바타가 추론할 수 있는 기능으로, 인공지능을 부여하여 사용자가 인터넷 채팅이나 게임을 할때 아바타로 하여금 사용자와의 인터렉션을 통해서 올바르지 않은 언어사용에 대한 인지를 쉽게 하고 개선의 효과를 높이며 지속적인 관심을 이끌 수 있는 인공지능을 가진 캐릭터 아바타를 제안하고자 한다.

In this paper, We propose the real-time monitor and control mechanism based-on web service for intelligent robot called URC(Ubiquitous Robotic Companion). URC is intelligent robot designed to interact with external digital device that can communicate through wire or wireless. In this paper, we designed the result of this study into the target robot called NETTORO and proved its practical worth. we optimized web-service technology in Embedded system environment so that can monitor and control indoors in remote place through acquired information from various sensors / actuators and then we designed. Also, we described command port to WSDL, so that can apply variously such as web server or application program in AXIS engine through gSOAP transmission protocol.

This paper proposes an optimization-based procedure to determine the parameters of the Apollo guidance law for Korean lunar lander mission. A lunar landing mission is formulated as a trajectory optimization problem to minimize the fuel consumption and the reference trajectory for the lander is obtained by solving the problem in the pre-flight phase. Some parameters of the Apollo guidance, which are coefficients of the polynomial used to define the guidance command, are selected based on the reference trajectory obtained in the pre-flight phase. A case study for the landing guidance of Korean lunar lander mission using the proposed procedure is conducted to demonstrate its effectiveness.

we can define the procedure of Authoring that it makes area cord and the reproduction prevent menu programmed into MPEG II video stream , Audio which is AC-3 audio stream and subtitle under its own category. And it makes process an attribute, an order and an operation, gives the last disk image (DVD). There are various types of Authoring tools in the market so that authoring tools can enable, encourage, and assist users ('authors') in the selection of tools that produce simple title and video production and editing suites. In this paper, we will compare and analyze authoring process in which image and sound are captured into DVD creation with IEEE 1394port with regard to Window system using generally with Desktop PC and the Macintosh of the PC on the system of Windows and OSX.

There are various process of Authoring tools in the market so that authoring tools can enable, encourage, and assist users ('authors') in the selection of tools that produce simple title, video production and editing suites. In this paper, we will compare and analyze authoring process in which image and sound are authorized into DVD with IEEE 1394port between Window system using generally with Desktop PC and the Macintosh that is based on OSX.

The development of information technology in a software-centered society as of today is a very important, and the training of software utilizing robots has become popular in recent years. This study proposes efficient SW convergence education by providing curriculum and contents for science + SW convergence education in conjunction with instruction block coding program. It also complements the limitations of existing unstructured chemistry experiment teaching aid, We have developed a 'chemical experiment paradigm' that integrates software education that can be linked with other classes.

Esterel is an imperative synchronous language that is used to develop memories, cache controllers, bus interfaces, and so on. An Esterel statement is called schizophrenic if it is executed more than once in an instant. A schizophrenic statement may cause problems when it is translated to hardware circuits; a circuit performs more than one reaction in a clock. Previous works claim that only local signal declarations and parallel statements may cause schizophrenic problems. However, control signals produced by a trap statement or data signals used by emit statements can cause schizophrenia. They are new schizophrenic patterns. Especially, schizophrenic problems caused by emit statements cannot be solved by a loop unrolling technique that is the key idea of previous curing techniques for schizophrenic problems. In this paper, we introduce and define the two schizophrenic problems.

Theme park automation system is developed by using the RFID sensor reader, IIS web server, ASP.NET and MSSQL database in this paper. Its operation is that park entrance people checked automatically when he who possessed the ta8 passed the reader acquisition bound and its tag information is sent to the host computer through the RS-232 data acquisition system. Tag information and time data will be stored in the RFID database tables and reused to extract and distribute the entrance people for the purpose of each arrangement of each entertainment devices. First of all, we developed interface program between host and reader and then, programmed the related web site and database connection function using ASP.NET with $C\#$ and MSSQ. We also design and make an production of external Ant. to extend the acquisition range up to $30\~40$ cm using copper PCB plate. We confirmed the performance through the RFID test bed site.

Due to the development of Internet, number of online documents and the amount of web services are increasing dramatically. However, there are several procedures required, before you actually find what you were looking for. These procedures are necessary to Internet users, but it takes time to search. As a method to systematize and simplify this repetitive job, this paper suggests a DotQuery based interactive search agent. This agent enables a user to search, from his computer, a plenty of information through the DotQuery service. which includes natural languages. and it executes several procedures required instead. This agent also functions as a plug-in service within general web browsers such as Internet Explorer and decodes the DotQuery service. Then it analyzes the DotQuery from a user through its own program and acquires service results through multiple browsers of its own.

In this paper, we describes the design and implementation of real-time management system for efficient operation via monitoring and control of MCC(Motor Control Center). The real-tine management system can be divided hardware(MCC panel) and software(management program). First, hardware is divided into load attaching motor and MCC components for working together control and data network. Second, software(management system) are consisted of communication interface, environment setting, data processing modules. The produced and implemented reduction model of MCC panel is pretested using m-PRO, iM-PRO devices, and HyperTerminal. For field test, MCC panel is tested by RS-232C/485, communication procedure in management system is certified by transmitting and receiving message using control command. By the experimental results, the implemented real-time management system can be used to operate MCC system.
