User's sensitivity is recognized as a very important parameter for communication between company, government and personnel. Especially in many studies, researchers use voice tone, voice speed, facial expression, moving direction and speed of body, and gestures to recognize the sensitivity. Multiplex modality is more precise than single modality however it has limited recognition rate and overload of data processing according to multi-sensing also an excellent algorithm is needed to deduce the sensing value. That is as each modality has different concept and property, errors might be happened to convert the human sensibility to standard values. To deal with this matter, the sensibility expression modality is needed to be extracted using technologies like analyzing of relational network, understanding of context and digital filter from multiplex modality. In specific situation to recognize the sensibility if the priority modality and other surrounding modalities are processed to implicit values, a robust system can be composed in comparison to the consuming of computer resource. As a result of this paper, it is proposed how to assign the weight of multiplex modality using implicit data.

Nonverbal immediacy plays a key role in interpersonal communication, inducing closeness and another interaction. This case study investigates the nonverbal behaviors in Human-Robot Interaction(HRI) focusing on immediacy, and how they affect perception of a robot. The results show that nonverbal immediacy, such as nodding and leaning forward, affect perceived interactivity. Nonverbal immediacy can be interpreted their meaning clearly when verbal feedback or other communication channel reinforcing them. Also, touch is found to affect come up with similar ones to the robot, because it is associated with concrete and discrete context. People tend to apply social rules to the robot, but they are more open to the unfamiliar robot compared to strangers. The findings in this study provide future HRI studies with heuristic implications by showing a direction and clarifying principles for composition of verbal and nonverbal expression.

A fingerprint is unique to each person and can be represented as a digital form. As the fingerprint is the part of human body, fingerprint recognition is much more easy to use and secure rather than using password or resident card for user authentication. In addition, as the newly released smart phones have built-in camera and fingerprint sensors, the demand for biometric authentication is increasing rapidly. But, the drawback is that the fingerprint can be counterfeited easily and if it's exposed to the hacker, it cannot be reused. Thus, the original fingerprint template should be transformed for registration and authentication purposes. Existing transformation functions use passcode to transform the original template to the cancelable form. Additional module is needed to input the passcode, so it requires more cost and lowers the usability. In this paper, we propose biometric authentication scheme that is economic and easy to use. The proposed scheme is consisted of cancelable biometric template creation, registration and user authentication protocols, and can control several security levels by configuring the number of fingerprints and scan times. We also analyzed that our scheme is secure against the brute-force attack and the active attacks.

Nowadays, 3-D(Three-dimensions) is used in various field such as Games, Movies, Animations etc. Especially the Role of 3-D computer graphic is being generalized by turnover of Screen from '2-dimensional' to '3-dimensional'. There are not enough data about 'Motion Capture' even though it plays main function in 3-dimensional movement. 'Motion Capture' could be also unfamiliar for people. And as a matter of fact, the use of this equipment is limited due to its high cost. Therefore, I studied the outline of Digital Motion Capture system and its application to 3-D game Character Animation. And I checked the movement of 3-D Character after transplanting the Motion Data to the 3-D Character. I acquired Motion Data by Optical Motion Capture Equipment which we possess and transplanted it into the 3-D Character then Implemented it as walking, running and hitting which are the basic motions of Expression.

The purpose of this study was to analyse characteristics of explanatory writing of scientifically gifted students who participated in gifted educational programs. Considering aspect of content of their explanations about cell, many of them explained the common characteristics of animal and plant cells, but a few of them did cellular characteristics of one kind of animal and plant. Some gifted students regarded cell membrane function as that of cell wall, and had a misconception that the cell was the smallest unit to consist human body. In terms of the structure of explanation, most of them didn't know the structural characteristics of explanatory writing. Finally, more than 50% of them had written using various ways to explain cell such as classifying, comparing, contrasting and exemplifying. Especially, all biologically gifted students had creatively explained drawing a picture. It was findings that the explanatory writing could be used as the instrument to evaluate knowledges of gifted students and suggested the elements of writing to teach scientific explanatory writing.

Since the middle of the 1960's, revitalization of the media art has showed a new paradigm shift as a alternative to existing art genre. According to advances in technology the form of art becomes various. Nowdays, art work which is mixed with media and other genre is popular because of hybrid culture. The image medium has flexibilty to incorporate with other genre because of medium character. The media installation that applied the image medium means to mixed work of sculpture and media. The sculpture and media has been broadened the field through the media installation. this study discuss art works projected image on sculpture among various media installation works. The materiality of the sculpture and the vision of the image mix up each other. It is associated with M. Merleau-Ponty's sens theory.

The purpose of this study is to suggest design characteristics of picture books for silver generation empirically through academic consideration of necessity and characteristics of picture books targeting silver generation. Through an analytical result of literature materials such as library and information science, pedagogy, and literature therapeutics, and aging phenomenon, picture books help mental and physical health of silver generation, but picture books for silver generation are insufficient in comparison with demand. Therefore, a theoretical basis of study and development of fairy tale books for silver generation is acutely needed. This study suggested that close attention for characteristics of silver generation is needed to solve a problem about dyslexia of silver generation in story, picture(expression, size, layout, structure, and color), and typography of characteristic factors of picture on designing fairy tale books for silver generation, suggesting needs to develop picture books reflecting characteristics such as visual organ, body function, and psychological factor of silver generation. In addition, design characteristics for composition of picture books for silver generation will be used as part of advanced data in a study on solid analytical data through an actual analysis on silver generation in the future.
