  • When the design profession started, design targets were mainly static hardware centered products. Due to the development of network and digital technologies, new products with dynamic and software-hardware hybrid interactive characteristics have become one of the main design targets. To accomplish the new projects, designers are required to learn new methods, tools and theories in addition to the traditional design expertise of visual language. One of the most important tools for the change is effective and rapid prototyping. There have been few researches on educational framework for interactive product or system prototyping to date. This paper presents a new model of educational contents and methods for interactive digital product prototyping, and it's application in a design curricula. The new course contents, integrated with related topics such as physical computing and tangible user interface, include microprocessor programming, digital analogue input and output, multimedia authoring and programming language, sensors, communication with other external devices, computer vision, and movement control using motors. The final project of the course was accomplished by integrating all the exercises. Our educational experience showed that design students with little engineering background could learn various interactive digital technologies and its' implementation method in one semester course. At the end of the course, most of the students were able to construct prototypes that illustrate interactive digital product concepts. It was found that training for logical and analytical thinking is necessary in design education. The paper highlights the emerging contents in design education to cope with the new design paradigm. It also suggests an alterative to reflect the new requirements focused on interactive product or system design projects. The tools and methods suggested can also be beneficial to students, educators, and designers working in digital industries.

  • This paper analyzes the implications of the change in the way China conducts public diplomacy, through an in-depth study of international education programs promoted under China's public diplomacy strategy. The leadership of Xi Jinping is now trying for China to become the top power in the world, not just a G2 country, based on China's economic growth over the past 40 years. Also, as a vision for the goal, the leadership is presenting the dream of the great revival of the Chinese nation. Currently, the international education program promoted at the level of public diplomacy in China is operated in an active, mid- to long-term manner within the national strategy, away from the past passive and responsive method. In other words, while China's past international education program was a passive model for dispelling the "Chinese Threat Theory," China's current international education program is evolving into an active model that can promote the "Chinese" order in the world.

  • This paper describes a computer vision system based on active IR illumination for real-time gaze discrimination system. Unlike most of the existing gaze discrimination techniques, which often require assuming a static head to work well and require a cumbersome calibration process for each person, our gaze discrimination system can perform robust and accurate gaze estimation without calibration and under rather significant head movement. This is made possible by a new gaze calibration procedure that identifies the mapping from pupil parameters to screen coordinates using generalized regression neural networks (GRNNS). With GRNNS, the mapping does not have to be an analytical function and head movement is explicitly accounted for by the gaze mapping function. furthermore, the mapping function can generalize to other individuals not used in the training. To further improve the gaze estimation accuracy, we employ a reclassification scheme that deals with the classes that tend to be misclassified. This leads to a 10$\%$ improvement in classification error. The angular gaze accuracy is about $5^{circ}$horizontally and $8^{circ}$vertically. The effectiveness of our gaze tracker is demonstrated by experiments that involve gaze-contingent interactive graphic display.

  • Recently, along with the recent development of deep learning technique, neural networks are achieving success in computer vision filed. Convolutional neural network have shown outstanding performance in not only for a simple image classification task, but also for tasks with high difficulty such as object segmentation and detection. However many such deep learning models are based on supervised-learning, which requires more annotation labels than image-level label. Especially image semantic segmentation model requires pixel-level annotations for training, which is very. To solve these problems, this paper proposes a weakly-supervised semantic segmentation method which requires only image level label to train network. Existing weakly-supervised learning methods have limitations in detecting only specific area of object. In this paper, on the other hand, we use multi-classifier deep learning architecture so that our model recognizes more different parts of objects. The proposed method is evaluated using VOC 2012 validation dataset.

  • Purpose: This study was conducted to investigate the independent role of sub-dimensions of job stress, DiSC(R) type of personal behavior, and organizational social capital on job satisfaction and to identify the structural relation among them. Method: Study subjects were 317 registrated nurses employed in 4 general hospitals in a metropolitan city. Results: As the results of multiple regression analysis, the factors influenced independently on overall job satisfaction were as follows; job stress were significantly decreased job satisfaction. Regarding DiSC, job satisfaction of influence type was significantly higher than that of conscientiousness type. Of sub-dimension of OCS, the higher common value and reciprocity were, the high over all job satisfaction, but in a sub-dimension(trust), the relationship was reversed. Major findings of structural equation model analysis were as follows. Regarding DiSC, there were founded only direct effect on job satisfaction(D, i, S>C in relations with peer and others, job performance, retrospectively). Regarding common value of OCS, there were founded significant positive direct effect and indirect effect via job stress on all sub-dimensions of job satisfaction. Regarding trust of OCS, there were founded negative direct effect alone on 2 sub-dimensions of job satisfaction(work itself, job performance). Regarding trust of OCS, there were founded positive direct and indirect effect on satisfaction towards work itself, and indirect effect alone on 2 sub-dimensions(relations with peer and others, job performance). Conclusion: Summing up above finding, to manage job satisfaction of nurses, it is suggested for nursing staffs to provide behavioral training programs according to type of DiSC(R) and to introduce strategic programs fostering organizational social capital such as common vision and reciprocity.
