To guide the guiding robot for the visually impaired carefully, the digital map to be used to search a path must be detailed and has some information about dangerous spots. It also has to search not only safe but also short path through the position data by GPS and INS sensors. In this paper, as the difference of the ability that the visually unpaired can recognize, we have developed the localization tracking system so that it can make a movement path and verify position information, and the global navigation system for the visually impaired using the GPS and INS. This system can be used when the visually impaired move short path relatively. We had also verified that the system was able to correct the position as the assistant navigation system of the GPS on the outside.

At the time when interest in the use of big data is rising in the face of the technological paradigm shift of the 4th industrial revolution, interest in the use of patented big data is increasing, especially as the proportion of intangible assets of companies increases. In addition to quantitative information, patent data contains various information such as unstructured text such as title, abstract, claim, citation and citation relations, drawings, and technology classification. It is judged that the use of treatment is important. Therefore, in this study, in order to systematically operate the innovative patent strategy framework and to secure a competitive advantage by strengthening the fundamental technological competitiveness of the company, we propose a method of using patent big data centering on the case of Company A, and verify its validity. I would like to suggest some implications. Through this, it is intended to raise awareness of the use of patent big data, and to suggest ways to use patent big data in connection with the company's company-wide strategy, business strategy, and functional strategy.

This paper describes characteristics of a bone conduction telephone which was developed for conductive hearing impaired persons to call without additional devices and results of its performance test. Not only the hearing impaired but also normal hearing persons can use this telephone because we developed a bone conduction vibrator with which they can perceive speech signal using functions of air conductive hearing as well as bone conductive hearing. It also has tone control function compensating hearing losses for the hearing impaired originating from their hearing characteristics, and using this function together with received volume control it has received volume range of 20dB in loudness rating, which is similar effect as what a telephone set with built-in received amplifier has. From results of articulation and intelligibility tests for 19 hearing impaired persons, we can see that if their bone-conduction hearing loss is 61dB or less, they can understand words or sentences and response well with this telephone.

현재 게임 역사를 보면 조이스틱의 인기가 눈에 띄게 떨어졌음을 알 수 있다. 비행 시뮬레이션 장르의 게임의 수가 적어지고 있기 때문이다. 조이스틱들은 일인용 슈팅 게임을 지원하지만 마우스나 컴퓨터 키보드에 견주어 보면 정확성이 떨어진다. 최근에 나온 소수의 게임들은 콘솔 PC와 연계가 되지만 PC 사용자들에게 자동 발사 기능을 사용할 것을 요구함으로써 사용자들에게 불편을 주었다. 본 연구는 기존의 게임 컨트롤러 구성요소를 분석하고, 아동의 조작능력과 신체발달과의 상호관계를 통해 아동의 놀이 발달기별 특징에 적합한 게임 컨트롤러를 개발한다는 것을 목적으로 한다.

A FSK receiver RF block has been developed for Dubaisat-1 Low Earth Orbit satellite. The receiver has Doppler tracking function which compensate frequency shift on uplink channel for commanding the satellite. It consist of LNA, downconverter and IF module. The IF module has Doppler tracking circuitry which sweep and lock on to input signal. It satisfies the requirement of the Dubaisat-1 in mass, power consumption, tracking speed and BER performance.

본 설계는 청각장애인을 위한 기술이다. 청각장애인은 일상생활에서 음성을 통한 의사소통이 어렵기 때문에, 비장애인과의 정보 격차를 줄이기 위한 '안경 부착형 커뮤니케이션 디바이스'를 개발하였다. Speech-To-Text 기술을 적용하여 음성이 인식되면 텍스트로 변환하여 출력한다. 따라서 음성에 대한 정보를 텍스트로 볼 수 있게끔 구현하였다. 또한 청각장애인은 소리로 파악할 수 있는 위험 요소에 노출되어 있다. 혹시 모를 안전사고에 빠르게 대처하고자 현재 위치 정보를 보호자에게 전송하는 기능을 구현하였다.

과학기술 학술활동은 원천기술 확보의 기반인 기초연구를 강화하기 위한 핵심요소이다. 논문과 학술지는 학술 커뮤니티에서 사전 연구기획과 사후 결과 활용의 핵심 수단으로써 중요한 기능을 담당하며 과학기술과 함께 발전해 왔다. 따라서 학술지 종수와 논문 발표 건수, 피인용 현황은 해당 주제 분야의 동향을 파악하는데 매우 중요하다. 이 연구에서는 최근 11년간 JCR 과학기술 주제분야(176개)별 논문 편수와 피인용도 증감 변화를 조사하여 새로운 주제분야(학문)의 생성과 성장가능성을 살펴 보았다.

청각 기능에 문제가 생겨 소리를 잘 듣지 못하는 청각장애인은 육아를 위해 베이비시터를 고용하거나 청각장애인용 소리감지 시스템을 사용하지만, 이는 비용적으로 부담이 될 수 있다. 이러한 문제를 해결하기 위해 사운드 센서 기반의 아기 울음소리감지 시스템을 제안한다. 이는 아기가 있는 곳에 소리감지 시스템을 설치하고, 일정 크기 이상의 소리가 감지되면 손목시계 모양의 웨어러블 디바이스에 진동을 발생시켜 아기가 울고 있음을 알려준다.

Web accessibility is presented as a legal obligation to ensure users can access and use information and functions equally in the domestic public website sector. This study introduces the researcher network based on social network analysis (SNA) in order to show the citation relationship by identifying the network among researches in the field of web accessibility. Based on the analysis of the relationship and citation of academic researchers in the domestic web accessibility field, confirm the process of creating a research network. It is a visualization element that shows the citation relationship as well as the relationship and citation form between the studies as a network. Through the process of creating the network, and it can be confirmed and can be usefully used for future academic research network analysis. It is meaningful in terms of analysis for about 17 years from January 2000 to March 2017, a total of 50 papers published in journals registered by the National Research Foundation of Korea and candidate journals. By combining the evaluation metrics for each researcher, evaluation target, evaluation method, and evaluation result for web accessibility, and applying weights, identify the research direction and evaluation research trends in Korea's web accessibility field related to the relevant field and web accessibility evaluation research trends, and related to the researcher trend network.

Source memory is a cognitive process that combines the representation of the origin of the episodic experience with an item. By studying this daily process, researchers have made fundamental discoveries that make up the foundation of brain and behavior research, such as executive function and binding. In this paper, we review and conduct a bibliometric analysis on source memory papers published from 1989 to 2020. This review is based on keyword co-occurrence networks and author citation networks, providing an in-depth overview of the development of source memory research and future directions. This bibliometric analysis discovers a change in the research trends: while research prior to 2010 focused on individuality of source memory as a cognitive function, more recent papers focus more on the implication of source memory as it pertains to connectivity between disparate brain regions and to social neuroscience. Keyword network analysis shows that aging and executive function are continued topics of interest, although frameworks in which they are viewed have shifted to include developmental psychology and meta memory. The use of theories and models provided by source memory research seem essential for the future development of cognitive enhancement tools within and outside of the field of Psychology.
