The contents of a new book currently in preparation are described. The dearth of books in the field of nuclear materials has left both students in nuclear materials classes and professionals in the same field without a resource for the broad fundamentals of this important sub-discipline of nuclear engineering. The new book is devoted entirely to materials problems in the core of light-water reactors, from the pressure vessel into the fuel. Key topics deal with the $UO_2$ fuel, Zircaloy cladding, stainless steel, and of course, water. The restriction to LWR materials does not mean a short monograph; the enormous quantity of experimental and theoretical work over the past 50 years on these materials presents a challenge of culling the most important features and explaining them in the simplest quantitative fashion. Moreover, LWRs will probably be the sole instrument of the return of nuclear energy in electric power production for the next decade or so. By that time, a new book will be needed.

This study aims to identify the needs of the disabled around E-books in order to develop such E-books. This study surveys the disabled, including the visually disabled and the deaf, on the usage of publications by disability type, the area of improvement to enhance E-book accessibility and the E-book functions for the disabled. The study surveys 196 people with the following key findings. First, the disabled have a preference for paper books over E-books. Second, the disabled read for practical tips in daily lives, cultural development and self development in such particular order. Third, the disabled have a negative view on function and variety of E-books, and want E-books to be customizable software-based rather than a simple platform-based.

Designing of the squirrel cage AC Traction Motor has many difficulties which has to be small size in order to be suitable into bogie frame, high efficiency and light weight. It means that induction motor for tractive purpose has to be different magnetic and electric loading ratio from industrial induction motor. This paper is devoted to an examination of how this ratio affects overall design concept and hence the main design points for traction motor. Also studied is tile changed coefficients of the magnetic and electric loading ratio squirrel cage induction motor for the traction purpose which has been already identified from tile reference book for industrial purpose induction motor.

In this paper. we present a new speech recognition system using DSP chip. DSP chip used TMS320c6711 of TI. We designed hardware system including acoustic model, word list and code book in flash memory. The word candidates are recognized based on CV, VCCV, and VC units HMM. This system can be applied to various electric ＆ electronic devices: home automation, robotics etc.

This paper presents a high speed ethernet communication and depulication method of communication to prevent decrease of reliability that was generated by high speed communication. Thus communication reliability was improved and this paper was considered that if any physical breakdown of line of communication occurred, other line of communication could operate collect. This paper used Flash memory for setting storage of backup data at Electric Car that have an humidity and a temperature and an impact. also improved reliability and besides matching data format to windows data format realized to confirm application program at PC or note book computer.

The wide spread of DC electric railway systems such as urban rapid transits including heavy rail and light rail transits has significant ramification as the stray currents from return conductor rails can cause the electrochemical interference, that is, the electrolytic corrosion of both rails and outside underground metallic infrastructures. The immature understanding of either the railway authority who is responsible for establishing the necessary provisions at the design stage or the affected parties makes it difficult to prepare the optimum range of solutions for the long-pending interference problem. In Japan, however, numerous assessment studies have been carried out on the stray current interference, by which protective guidelines are provided by "Electrolysis Committee". In this paper, we review a guide book from "Tokyo Electrolysis Committee", namely, "Protective Methods for Stray Current Corrosion".

도서관에서 사용자들이 책을 빌리거나 반납하기 위해서는 'ㄱ'부터 시작하여 'ㅎ'까지 순서대로 진열이 되어 있는 책의 위치를 찾아가야 한다. 책을 반납할 때, 책을 다시 제자리에 놓는다면 문제가 없지만 사람들이 책을 읽고 진열대에 다시 넣는 과정에서 착오가 생겨, 다른 진열대 넣는 경우, 도선관 사서가 이를 찾아내, 올바른 위치에 놓아야 한다. 또한, 사용자들이 반납한 책들을 도서관 사서가 실수로 다른 곳에 진열할 수도 있다. 본 논문에서는 이러한 문제점을 줄이기 위해, 지능형 모바일 증강현실에 기반한 도서 위치 관리 방법을 제시한다. 제시된 방법에서는 책의 위치 정보, 각도 등 다양한 센싱 정보를 활용하여 진열된 책들이 제자리에 있는지를 실시간으로 점검하고 책의 위치가 잘못 되었을 경우, 도서관 사서에게 이를 알려 책의 위치를 바로 잡도록 하였다.

The main purpose of this study is to prepare an outline for developing of the module-type text-book system on the customize curriculum management and Contents Systems that achieve self-study systems to make the students adopt themselves into new study atmosphere and maximize the result of study on Osan college in Electric-Electronic field. Questionnaire posed to analyze the demand of teaching materials to the students, and professors and also to find characteristics of students in Osan college. The SPSSWIN/PC+ statistics package was used to assay the collected answers. And simple frequency with percentage, average, and standard deviation were calculated to check the entire trend and actual state of teaching. Therefore, the improvement of the existing teaching materials was demanded while the fundamental ability to study of general students is declining. Consequently, it is necessary to introduce new teaching materials which are simple, easy, and organized to offer the students study desire and interest.
