This paper introduces a tactilely transparent soft glove composed of soft materials and flexible structures. Although it is hard to achieve a high grasping force with conventional grip-assist gloves made from soft material, the proposed glove can exert a high force by using a novel structure. This structure has a triangular shape composed of flexible structural frames, soft fabric, and belts. It can produce grip-assist moment compliantly without harmful force or misalignment with the human fingers. The whole finger part that comes into contact with objects is made of thin and soft fabric in order to facilitate sensation transference. The proposed tactilely transparent soft glove enables the user to manipulate various objects owing to both the softness and high grasping force; it helps lifting heavy weight objects as well as permitting delicate tactile feeling on the palm and fingers. The proposed concept was applied to a two-finger grip-assist device for validation. In addition, the experimental results regarding grasping objects, fingertip force, and grasping force are presented.

The 2015 revised curriculum aims to cultivate creative convergence talent. In this regard, SW education needs to study various convergence education methods to enhance computational thinking. The purpose of this study is to analyze the effects of SW convergence education centered on reading education and robot utilization education to improve computing thinking ability. For this purpose, SW education teaching and learning was designed by combining SW education using card coding-based robots with reading education based on interactive works and reading on the whole work. As a result, the convergence education between reading and SW improved all three areas of the concept, practice, and perspective of computational thinking ability and increased the learner's satisfaction.

This study aims to investigate industry needs for convergence education in the field of nano-technology, bio-technology, robot, and design. Firstly, the area of convergence technology in nano-tech, bio-tech, robot, and design fields was examined through the literature review and case study. The areas were validated by the experts review who consisted of four industry experts and four professors in the relevant fields. Second, a questionnaire was developed for investigating industry's needs on convergence education. The questionnaire consisted of three parts: 1) awareness of necessity for convergence education, 2) the needs for convergence new technology education from the perspective of industry, and 3) opinions on convergence education. The questionnaire was validated by three engineering education experts. Third, the survey was conducted in cooperation with the Sector Council of Industrial Resources. A total of 400 respondents responded to the questionnaires: 98 in the nano-technology field, 74 in the design field, 58 in the robotics field, and 170 in the bio-technology field. Fourth the industry needs for convergence education were analyzed and implications were suggested. The results of this study are expected to provide a guideline for developing convergence education programs in higher education.

지식경제부에서는 학교교육의 다양성 확대를 지원하고 체계적인 로봇교육 방안을 마련하고자, 초등학교 68개교를 대상으로 교구로봇과 교사 연수 등 교사의 로봇활용 지원체제를 구축한 후 교구로봇 시범교육사업을 실시하였다. 따라서 본 논문에서는 초등 방과후학교의 교구로봇 시범교육사업에 대한 현황을 분석하여, 향후 교구로봇 확대사업에 대한 기초 자료 분석결과를 제공하고자 한다. 이를 위하여 시범교육사업 대상학교의 교육 개설 현황, 교구 및 교재 이용, 교 강사 현황과 학생만족도 등을 조사하였다. 그 결과 대부분의 초등학교에서 학생들의 창의력 향상, 로봇에 대한 관심 증대 등의 효과가 있는 것으로 나타났으며, 적극적으로 수업에 참여하고 높은 집중 정도를 나타내는 것으로 분석되었다. 하지만 교재, 교구에 대한 개선 요구사항이 많은 것으로 나타나 학생들의 수준에 맞는 적절한 교재와 학생들의 다양한 활동을 이끌어 낼 수 있는 교구의 구성이 뒷받침 되어야 할 것으로 보인다.

An effective dual-mode camera system(a passive wide-angle camera and a pan-tilt-zoom camera) is proposed in order to improve the performance of visual surveillance. The fixed wide-angle camera is used to monitor large open areas, but the moving objects on the images are too small to view in detail. And, the PTZ camera is capable of increasing the monitoring area and enhancing the image quality by tracking and zooming in on a specific moving target. However, its FOV (Field of View) is limited when zooming in on a specific target. Therefore, the cooperation of wide-angle and PTZ cameras is complementary. In this paper, we propose an automatic initial set-up algorithm and coordinate transform method from the wide-angle camera coordinate to the PTZ one, which are necessary to achieve the cooperation. The automatic initial set-up algorithm is able to synchronize the views of two cameras. When a moving object appears on the image plane of a wide-angle camera after the initial set-up positioning, the obtained values of the wide-angle camera should be transformed to the PTZ values based on the coordinate transform method. We also develope the PTZ control method. Various in-door and out-door experiments show that the proposed dual-camera system is feasible for the effective visual surveillance.

A tape feeder of a SMD(Surface Mount Device) mounter is a device that sequentially feeds electronic components on a tape reel to the pick-up system of the mounter. As components are getting much smaller, feeding accuracy of a feeder becomes one of the most important factors for successful component pick-up. Therefore, it is critical to keep the feeding accuracy to a specified level in the assembly and production of tape feeders. This paper describes a tape feeder inspection system that was developed to automatically measure and inspect feeding accuracy using machine vision. It consists of a feeder base, an image acquisition system, and a personal computer. The image acquisition system is composed of CCD cameras with lens, LED illumination systems, and a frame grabber inside the PC. This system loads up to six feeders at a time and inspects them automatically and sequentially. The inspection software was implemented using Visual C++on Windows NT with easily usable GUI. Using this system, we can automatically measure and inspect the quality of all feeders in production process by analyzing the measurement results statistically.
