The final aim of the present study is to build a system of converting a color image into musical elements based on a synesthetic perception, emulating human synesthetic skills, which make it possible to associate a color image with a specific sound. This can be done on the basis of the similarities between physical frequency information of both light and sound. As a first step, an input true color image is converted into hue, saturation, and intensity domains based on a color model conversion theory. In the next step, musical elements including note, octave, loudness, and duration are extracted from each domain of the HSI color model. A fundamental frequency (F0) is then extracted from both hue and intensity histograms. The loudness and duration are extracted from both intensity and saturation histograms, respectively. In experiments, the proposed system on the conversion of a color image into musical elements was implemented using standard C and Microsoft Visual C++(ver. 6.0). Through the proposed system, the extracted musical elements were synthesized to finally generate a sound source in a WAV file format. The simulation results revealed that the musical elements, which were extracted from an input RGB color image, reflected in its output sound signals.

Enterprise's executives who believe methodologies the theories prescribe consideration of consumer as rational and reasonable behavior. However, by recent investigation, consideration of consumer can be defined behavior that is occurred by sensibility. These consideration of consumer affect to a process that purchase a product, consumer's purchase decision process. Consumer make a purchasing decision with sensible criterion, respective of quality after all rather than various rational criterion like price, efficiency and usefulness. Brand image has sensible value to thought in the mind about a product and affect to purchase products. Hence building brand image through positive sensitivity is significant point in strengthening. Research from this point of view makes a content advance with improving product process along storytelling method which kind of affective, sensible communication way as a factor of strengthening brand image.

This study aims to validate the effectiveness of CAVE system with an Arm-Master in the evaluation of virtual prototypes. A virtual kitchen with a refrigerator was presented in the CAVE system. Subjects put in and pull out virtual objects by using the Arm-Master. Twelve subjects, six males and six females, participated in the six experimental conditions : three types of refrigerator door grips and two reaction forces. After each trial, subjects evaluated a door grip of the virtual refrigerator in terms of easiness of operation, similarity in force, presence etc. The results show the mean values of vortical-type door grips are greater than the horizontal pocket-type door grip. Also the subjects preferred 5N in the reaction force of the Arm-Master rather than 15 N when they open and close virtual door. Unexpectedly, female subjects significantly marked low scores in the evaluation terms compared ruth mali subjects. It explains the Arm-Master should be modified much more if it works effectively in design evaluation.

Cyberspace is on its way to experience dynamic change, hereby encompassing technical and social diversities and multiplicities. The internet, with a history of no more than 10 years, has drastically changed the way, meaning and conduct of our lives, the structure and function of society and communication. Even in psychology, in which the purpose is to scientifically look into the human mind and explore its behavior, the in-depth inquiry into the human behavior and psychological features of the cyberspace have become an increasingly important issue. Research suggests that psychological features and concepts brought about during the process of communication in cyberspace have been influenced by the digital mode following the analogue one, and by the online mode following the off line one. It also suggests that, with new issues peculiar to information society, cultural structures should be re-conceptualized, reconstructed and reevaluated in various fields. This approach to the changing role, meaning and style within society should be rearranged and referred to as cyber psychology.

Because of the development of digital technologies and information-oriented products, the importance of user interface design and usability are increasing in recent year. So we need a systematic and rational way to measure and manage how effective the improvement of user interface is. The purpose of this study is to develop measurable ‘Usability Improvement Index' which signify how much usability has improved in user interface design. First, I made the framework of measuring and evaluating usability through analysis of existing usability metrics and previous studies. Then, I suggested the process of calculating 'Usability Improvement Index' based on categorizing characteristics of measurable usability and definition of usability metrics. The process is as in the following : measuring the present level of usability, analysis of problems, making alternative user interface design, measuring the improved level of usability, calculating Usability Improvement Index. For verification, the case study on application of Usability Improvement Index to usability improvement of application software of digital camcorder presented. This study is expected to assist 'goal oriented user interface design' and to manage usability systematically.

The effects of artificial intelligence technology is social science research as research on the impact on industry and changes in daily life, etc. This means that developing 'emotion AI' will prepare 'next-generation 3D-vector-sensitive AI'. This suggests the main keywords of the tertiary AI decision-making power. Particularly important results will be achieved because of the importance of current unethical learning and the implementation of decision-making systems that reflect ethical value judgments. This is a data based simulation, and required (1)Available data, (2)the technology for the goal of simulation. This takes into account the general content of the intended simulation based research. Currently, existing researches focus on meaningful research motivation, but this study presents the direction of technology. So, empirical analysis is consistent with the decision-making power of each country vs. new technology firms for AI on ehtic responsibility. As a result, there is a need for a concrete contribution and interpretation that can be achieved for the ethic Responsibility, on the technical side of AI / ML. In AI decision making, analytic power of human empathy should be included tech own trust.

This study was to examine how visual angle of matrix corresponding to the physical properties of P300 speller and eye gaze corresponding to the user's personal characteristics influence on the accuracy of P300. Visual angle of the matrix was operated as the distance between the user and the matrix and three groups were composed: 60 cm group, 100 cm groups, and 150 cm group. Eye gaze methods was consisted three conditions. Head moving condition was putting eye gaze using head, pupil moving condition was moving pupil with the head fixed, while the eye fixed condition is to fix the eye gaze at the center of the matrix. The results showed that there was significant difference in the accuracy of P300 speller according to the eye gaze method. The accuracy of the head moving condition was higher than the accuracy of pupil moving conditions, accuracy of pupil moving conditions was higher than the accuracy of the eye fixed conditions. However, the effect of visual angle of matrix and interaction effect were not significant. When P300 amplitude of target character was measured depending on how you stare at the target character, P300 amplitude of the head moving condition was greater than P300 amplitude of the pupil moving condition. There was no significant difference in the error distribution in head moving condition and pupil moving condition, while there was a significant difference between two eye gaze conditions and fixed gaze condition. The error was located at the neighboring characters of the target character in head moving condition and pupil moving condition, while the error was relatively distributed widely in fixed eye condition, error was occurred with high rate in characters far away from the center of matrix.

Optogenetics is the combination of optical and molecular strategies to control designated molecular and cellular activities in living tissues and cells using genetically encoded light-sensitive proteins. It involves the use of light to rapidly gate the membrane channels that allows for ion movement. Optogenetics began with the placing of light-sensitive proteins from green algae inside specific types of brain cells. The cells can then be turned on or off with pulses of blue and yellow light. Using the naturally occurring algal protein Channelrhodopsin-2 (ChR2), a rapidly gated light-sensitive cation channel, the number and frequency of action potentials can be controlled. The ChR2 provides a way to manipulate a single type of neuron while affecting no others, an unprecedented specificity. This technology allows the use of light to alter neural processing at the level of single spikes and synaptic events, yielding a widely applicable tool for neuroscientists and biomedical engineers. An improbable combination of green algae, lasers, gene therapy and fiber optics made it possible to map neural circuits deep inside the brain with a precision that has never been possible before. This will help identify the causes of disorders like depression, anxiety, schizophrenia, addiction, sleep disorder, and autism. Optogenetics could improve upon existing implanted devices that are used to treat Parkinson’s disease, obsessive-compulsive disorder and other ailments with pulses of electricity. An optogenetics device could hit more specific subsets of brain cells than those devices can. Applications of optogenetic tools in nonneuronal cells are on the rise.

Previous works have observed that persons who have experienced social exclusion have lower perceptions of body temperature and environmental temperature, and seek physical warmth such as warm drinks and warm water shower. The present study aimed to expand the results of these previous works to the dimensions of color emotions or color symbols. Hence, four experiments were conducted in which pictures of people with warm or cold colors applied to them were shown to the subjects, who were asked to evaluate the people in the pictures to determine whether their preferences changed depending on their perception of social exclusion. The results showed that the subjects with perceived social exclusion had stronger preferences for people in warm colors over those in cold colors, but the subjects without perceived social exclusion had no differences in their preferences for the people in the two types of colors. This study is significant in that it expanded the compensation hypothesis, which states that people try to compensate their psychological loss by pursuing external goals from the physical dimension to the emotional and symbolic dimensions. Furthermore, this study has implications in that it proposes the need for warm emotions in places where people who have experienced social exclusion are treated, such as psychological counseling centers.
