Railway sign(graphic sign, diagraphics) designs require good recognition with universality to transmit accurate and speedy information as they connect people around the station and other transport systems. An important point of signs is how to design and deliver the contents to the viewers as a communication service tools. It needs to establish design guidelines with standardization and unified system to show their contents and images clearly like common language with visuality, attractivity and generality. These requisites are important for both aesthetics legibility and unified standards to maximize the effectiveness of pictograms for the use of the general public, who require systematic suggestion and management.

웨어러블 단말기에서 가장 문제가 되고 있는 부분은 디스플레이 장치이다. 이러한 문제의 해결 방안으로 안경처럼 착용하는 모니터의 일종인 HMD(Head Mounted Display)가 개발되어 사용되고 있다. 그러나 HMD에서도 문제점은 존재한다. HMD를 착용하고 멀티미디어 콘텐츠를 감상하는 도중에 콘텐츠를 선택하거나 실행할 경우 버튼, 키, 마우스 등을 조작해야 하나, HMD를 착용한 경우에는 매우 불편하다. 이러한 문제점을 해결하기 위한 가장 근본적인 방법은 새로운 인터페이스를 개발하는 것이다. 따라서 본 논문에서는 제스처 인식 기반의 웨어러블 영상시청 시스템을 개발하였다.

This paper explores new techniques that are based on a hidden-layer linear transformation for fast speaker adaptation used in deep neural networks (DNNs). Conventional methods using affine transformations are ineffective because they require a relatively large number of parameters to perform. Meanwhile, methods that employ singular-value decomposition (SVD) are utilized because they are effective at reducing adaptive parameters. However, a matrix decomposition is computationally expensive when using online services. We propose the use of an extended diagonal linear transformation method to minimize adaptation parameters without SVD to increase the performance level for tasks that require smaller degrees of adaptation. In Korean large vocabulary continuous speech recognition (LVCSR) tasks, the proposed method shows significant improvements with error-reduction rates of 8.4% and 17.1% in five and 50 conversational sentence adaptations, respectively. Compared with the adaptation methods using SVD, there is an increased recognition performance with fewer parameters.

본 논문에서는 관람객 얼굴 표정 및 제스쳐 인식을 기반으로 인터렉티브 디지털콘텐츠의 문제점 추론 시스템을 제안한다. 관람객이 콘텐츠를 체험하고 다른 장소로 이동하기 전까지의 행동 패턴을 기준으로 삼아 4가지 문제점으로 분류한다. 문제점 분류을 위해 관람객이 콘텐츠 체험과정에서 나타낼 수 있는 얼굴 표정 3가지 종류와 제스쳐 5가지를 구분하였다. 실험에서는 입력된 비디오로부터 얼굴 및 손을 검출하기 위해 Adaboost algorithm을 사용하였고, mobilenet v1을 retraining하여 탐지모델을 생성 후 얼굴 표정 및 제스쳐를 검출했다. 이 연구를 통해 인터렉티브 디지털콘텐츠가 지니고 있는 문제점을 추론하여 향후 콘텐츠 개선과 제작에 사용자 중심 설계가 가능하도록 하고 양질의 콘텐츠 생산을 촉진 시킬 수 있을 것이다.

The purpose of this study is to investigate teachers’ recognition in Food/Nutrition, Textile/Clothing part in Home Economics Text Book of Middle School and to provide the basic data for the improvement of its curriculum. 147 Home Economics teachers in Taegu city and Kyungsangbukdo area responded to the questionnaire. The results are summarized as follows: 1. Most of Home Economics teachers have graduated Dept. of Home Economics Education and have ever taken teacher training. And even those who ever taken teacher training are not satisfied with training curriculum contents. Therefore, the result of this study shows that teacher training curriculum contents should be improved so as to be helpful for the actual teaching and learning. 2. In terms of the suitability of contents of food & nutrition and contents of textiles & clothing to the student’s learning development levels, the degree of suitability is in the order of nutrition & health, nutrition in adolescence, food selection, kinds and functions of nutrients in food & nutrition curriculum, and in the order of suitable clothing, mixture rate of fabrics, purchase of clothing, clothing in adolescence, clothing selection. The contents of making processed foods and usage of sewing machine of the existing text book have turned out not to be appropriate. 3. Most teachers suggest that dietary guideline for health, misconception about food & nutrition selection of ready-made suit suitable clothing for situation & character as well as the contents of the existing text book should be included in the new text book.

지능형 로봇이란 인간과 비슷하게 시각, 청각 등의 감각기관을 기반으로 자율적으로 판단하고 행동하는 독립적 자율구동 시스템을 말한다. 인간은 언어 이외에도 제스처와 같은 비언어적 수단을 이용하여 의사소통을 하며, 이러한 비언어적 의사소통 수단을 로봇이 이해한다면, 로봇은 인간과 보다 친숙한 대상이 될 수 있을 것이다. 이러한 요구에 의해 얼굴인식, 제스처 인식을 비롯한 HCI(Human-Computer Interaction) 기술들이 활발하게 연구되고 있지만 아직 해결해야 할 문제점이 많은 실정이다. 본 논문에서는 지능형 로봇을 위한 기반 기술 중 인간과의 가장 자연스러운 의사소통 방법의 하나인 제스처 인식 기술에 대하여, 최근 연구 성과를 중심으로 요소 기술의 중요 내용과 응용 사례를 소개한다.

Image projectors can turn any surface into a display. Integrating a surface projection with a user interface transforms it into an interactive display with many possible applications. Hand gesture interfaces are often used with projector-camera systems. Hand detection through color image processing is affected by the surrounding environment. The lack of illumination and color details greatly influences the detection process and drops the recognition success rate. In addition, there can be interference from the projection system itself due to image projection. In order to overcome these problems, a gesture interface based on depth images is proposed for projected surfaces. In this paper, a depth camera is used for hand recognition and for effectively extracting the area of the hand from the scene. A hand detection and finger tracking method based on depth images is proposed. Based on the proposed method, a touch interface for the projected surface is implemented and evaluated.

The purpose of this study is to analyze elementary and secondary school teachers' recognition about engineering education in elementary and secondary school. For this, we surveyed elementary and secondary school teachers. The result of this study is as follow. First, most teachers perceived that engineering positively affect national competitiveness and development. They also found that engineering education helps student to select natural science and engineering field career. Moreover, they perceived that engineering contents are not applied in elementary and secondary schools curriculums, hence it does not stimulate interest in engineering. Therefore, they perceived that if engineering education contents are systematically applied in formal curriculum, it will have a positive effect on current engineering education. Second, most teachers perceived that roles of engineering education are to make students learn creative design and problem solving process and inform about the engineering field career. They perceived that the best grade to start engineering education is 4~6 grade in elementary school and the best way to apply engineering education is through distributing engineering education contents to related subjects. They also perceived that technology subject has the most relation to engineering education and science subjects; mathematics subject follow after.
