1인 미디어가 개인의 욕구분출과 인터넷의 발달이 맞물리면서 정보화 시대의 대세로 자리매김하였다. 하지만, 인터넷의 접근성은 의도치않던 사생활 침해 우려를 낳고 있으며 폐쇄적인 SNS의 수요를 중가시키는 실정이다. 본 논문에서는 PWW(Person Wide Web)를 이용하여 1인 미디어를 생성하고 타인과 공유하는 1인 미디어 체계를 제시한다. PWW는 스마트폰과 모바일 앵커, 개인의 클라우드 스토리지로 구성된 웹 기반의 정보체계이다. 현장의 객체에 부착된 모바일 앵커로부터 개인 클라우드 저장소의 주소를 얻고 그 주소에 저장된 웹문서를 가져와 스마트폰의 웹뷰에서 처리한다. 또한, PWW 방식의 1인 미디어 체계를 설명하고 현장에서 1인 미디어를 활용한 예를 제시한다. WWW 방식의 1인 미디오와 PWW 방식의 1인 미디어의 보안성을 비교, 분석하였으며, PWW 방식의 1인미디어가 더 높은 보안성을 갖는것을 보였다. 1 person media is becoming the leading trend among several media in the Internet era exploiting the individual desire of showing off. But, the vast accessibility of Internet produces the worry about privacy risk, which concludes in the increasement of closed SNS. In this paper, we propose a system based on PWW (Person Wide Web) where a person is producing a media and share it with other persons. PWW is an information system which consists of a smart-phone, mobile anchors, a standard web document, and his own cloud storage. An information consumer gets the link using his smart-phone from the mobile anchors attached on the objects in the field. The web browser in the smart-phone obtains the web documents designated by the link and presents it. We also explains the 1 person media system based on PWW and presents the example utilized in the field. We compared and analyzed the security factor of the system based on between WWW and PWW, and concluded that PWW is better than WWW in the aspect of security.

In this paper, a prototype of the Bridge-Transported Servo Manipulator (BTSM) system is introduced, which has been developed to do operation and maintenance jobs remotely in a hot cell. The system consists of a telescopic transporter, a slave arm, a master arm, and a control system. Several tests such as a positional tracking, a weight handling, reliability, and operability have been performed and test results are presented. Based on the test results, an upgraded system which will be used during demonstrations of the advanced spent fuel conditioning process (ACP) has been designed.

In this paper, fault tolerant mechanisms are presented for a servo manipulator system designed to operate<br/> in a hot cell. A hot cell is a sealed and shielded room to handle radioactive materials, and it is dangerous for<br/> people to work in the hot cell. So, remote operations are necessary to handle the radioactive materials in the<br/> hot cell. KAERI has developed a servo manipulator system to perform such remote operations. However,<br/> since electric components such as servo motors are weakened with radiation, fault tolerant mechanisms have<br/> to be considered. For fault tolerance of the servo manipulator system, hardware and software redundancy has<br/> been considered. In the case of hardware, radioactive resistant electric components such as cables and<br/> connectors have been adopted and motors driving a transport have been duplicated. In case of software, a<br/> reconfiguration algorithm accommodating one motor's failure has been developed. The algorithm uses<br/> redundant axes to recover the end effector's motion in spite of one motor's failure.
