  • Although, recently, studies on Internet banking users' behavior have been frequently found in some academic journals, most of them have ignored security anxiety which may be considered as important factors influencing usages of Internet banking. We propose an research model for Internet banking users which is an extended version of the Technology Acceptance Model(TAM) by adding new variable, security anxiety. For empirical support of our model, we survey for 298 samples and analyze it by structured equation model(SEM). In result, our proposed model is proved as a valid one in which all hypotheses except one are accepted and the values of model fitness are relatively high.

  • In today's hyper-competitive business environment, Radio Frequency Identification (RFID) technology is expected to enhance the operation efficiency of supplying chain management in both manufactures and retail industries. However, the widespread deployment of RFID tags may create new threats to user privacy, due to the powerful tracking capability of the tags. Many authentication protocols for RFID have been proposed. They are helpful preventing passersby being scanned to determine what articles they are carrying. However, most of them would not prevent the bigger physical tracking problem of RFID, especially when being tracked by the 'constellation' of products they carry. We proposed this RFID scheme to prevent these tracking problems.

  • With the internet(World Wide Web) widespread among people after 1995, Information Communication Network, which is basic structure of the internet, is rapidly changing into fiber optics communication. Voice-centered Circuit Traffic is rapidly changing into Internet-centered Packet Traffic and Optics Communication Technology can transmit 1Tb/s thousands kilometers away. The information conveyed through the internet is being diversified - from simple information based on text to bulky multimedia information such as auido & video data. So the demand for higher speed, high storage Router is on the crease. With the continued increase of Internet Traffic, Router for Core Backbone System will be much more needed.

  • 최근 국내에서 신 변종 공격이 대량으로 발생함에 따라, 한정적인 보안전문 인력과 기존의 장비로 분석 및 대응하는데 어려움이 있다. 본 논문에서는, 대량으로 발생하는 침해사고에 대해 분석 우선순위를 확인하고자, 침해사고에 활용된 침해지표들의 위협을 분석하고 이를 정량적인 값인 침해지표 위협수준(TL_IoC, Threat Level of IoC)로 도출하는 방안을 제안한다. 이를 통해, 침해지표의 위협수준을 직관적으로 확인함으로써 침해사고의 대응수준을 신속하게 판단하고, 위협수준이 높은 침해사고에 대해 능동적으로 빠르게 분석함으로써 대량의 침해사고를 효율적으로 대응할 수 있다.

  • In welding, there is much dangerous element. Workers who are exposed to working field of welding may be infected with industrial diseases. To solve these problems, many studies has been carried out. It is a good method to make welding automation in the distance and internet makes it possible. If internet is used, welding can be carried out without the limitation of time and place. On this study, welding by using internet is studied. By using internet, computer which has interface with welding machine is connected to computer in the distance and welding is carried out with the signal of computer in the distance. Basically the connection of computers is made by two program-Server and client windows program-which have functions which are needed for control of XYZ table and welding machine. Through these program, the motion of welding torch which was mounted on XYZ table, the starting and ending of welding is controlled and monitored with a camera. Also, signal-welding current and arc voltage-is measured and displayed.

  • Now, the world is faced with radical changing in the new rvolution which is followed by speading and utilization of internet. The domain names which are currently used on the internet are unique throgh out the world. Therefore, U.S government positively intervenes in the management of the internet domain name for the effective implementation. The thesis descrbes research of the korean domain name system which allows us to use korea character into current internet domain name system and implements the architecture of the korean domain name system by analysis the structure and behavior of domain name server.

  • 본 논문에서는 스마트폰을 이용한 잔돈 관리 시스템에 대해 제안한다. 현재 동전의 실거래양도 적을뿐더러 사람들의 경우에는 동전이 생겼을 경우 동전을 주머니에 넣고 다니는 불편을 겪고 있다. 이에 스마트폰을 이용하여 잔돈을 직접 받는 것이 아니라 이를 어플을 통해 마일리지 형태로 적립하여 추후에 자신의 계좌로 저금한 금액을 출금할 수 있으며 저금한 금액의 일부를 자동 기부함으로 아름다운 사회 만들기의 일환에 도움이 된다. 이는 동전휴대의 불편함을 개선 가능하고 함부로 사용가능한 동전사용을 막아 저축의 기능도 있으며 동전이 유통되지 않아 계속 더 큰 돈을 들여 만드는 한국은행의 돈을 줄일 수 있을 것으로 예상된다.

  • Requirements for device networks differ greatly from those of data(business) networks. Consequently, any control network technology which uses a fieldbus protocol is, in general, different from IP network protocol TCP/IP. One needs to integrate fieldbus protocol and TCP/IP to realize distributed control over IP network or internet. This paper suggests a basic concept that can be applied to distributed control over IP network or internet. Specifically, LonWorks technology that uses LonTalk protocol is reviewed as device network. LonWorks technology provides networked intelligent I/O and controllers which make it a powerful, expandable solution. It is also addressed that many hardwired PLCs can be replaced by LonWorks devices. Connecting these remote LonWorks networks to the Internet can provide a powerful, integrated, distributed control system.

  • This research presents new type of remote monitoring and control solution of PLC that can be used bi-directional and efficient management of factory automation through internet. This system has client/server architect for information handling between PLC and remote computer where a user can control and monitor target PLC. Actually the authors redirect RS232C connection between PLC and server computer into Internet connection between PLC and remote client computer using supplied PLC tool program So user feel like in front of PLC panel when he operates remote PLC through Internet. Each client/server program is constructed with Java language for security. In this paper the internet-based remote control system was proposed and proved validity by being applied to redirection of PLC control for factory automation.

  • 이 논문에서는 디지털 시그널 프로세싱에 적합하지 않은 RISC타입의 DB-X 마이크로콘트롤러를 이용하여 MP3 플레이어를 구현한 방법을 제안한다. DB-X 에는 DSPA 모듈이 있어 FIR, FFT 등 계산이 많이 요구되는 부분을 DSP 수준으로 빨리 연산해 줄 수가 있으며 SSI 모듈이 있어서 44.1khz의 샘플링 주기를 가지는 D/A 코덱과 연결할 수가 있다. 또한 SSI와 음성 데이터가 저장되어 있는 메모리 사이를 CPU 부담없이 데이터를 전송하기 위한 DMA 모듈이 있어 MP3 데이터를 프레임 단위로 디코딩할 때 더블 버퍼링 기법을 쉽게 사용할 수가 있다.
