멀티플랫폼을 지향하는 유비쿼터스 e-Loaming 시스템에서는 보다 다양한 매체를 통한 온라인 학습이 이루어지기 때문에 상호작용 촉진이 매우 중요하다. 본 논문에서는 온라인 학습에서 매우 절실히 요구되는 상호작용 촉진 학습 설계를 사이버강의에 적용하고 피드백을 통해서 고찰하였다. 향후에는 감성공학과 같은 기반기술을 적용한 보다 효율적인 상호작용을 지원하는 학습 설계가 모색되어야 할 것이다.

For design research of teenagers' posture correcting shirt, postures of teenagers were analyzed and became the base of inventing suitable patterns. The subjects of this study were 198 of both female and male middle school students from the city of Seoul. Students' postures in classroom and length change of body surface were observed and analyzed; based on this, total of 5 postures was selected, and length changes of body surface were applied. The patterns in this study were designed with stretch material to help antagonism by muscle movements. Each fabric that was used in this study had 110% of stretch, 120~140% of stretch, and 150~170% of stretch. Both of one-way-fabric and duplex-fabric were used in this study, depending on application site.

In order to help develop more comfortable seat cover fabrics, this study primarily surveyed the actual using conditions and the consumers' opinions of the seat cover fabrics. The results of this study were as follows: 1) The colors of seat cover fabric were mostly achromatic. Regarding comsumers' satisfaction on the colors of seat cover fabric, comsumers in their 20's were less satisfied than other age groups. Most unsatisfied consumers prefered bright colors. 2) On the materials of seat cover fabric, synthethic leather and woven were most widely used. Real leather was most prefered due to its luxury and tactile sensation. Woven was secondarily prefered due to its price and tactile sensation. About fourty percent of consumers covered the seat with other cover fabrics because of soil and other reasons. It will be useful if they could choose and change the seat cover fabircs with different materials and colors. 3) When consumers used the seat cover fabrics, the problems that they indicated were not durability and colorfastness but low breathablity during sweating, static electricity, soil, firmness, and cool sensation at the first contact.

In this paper, we propose the ergonomic design method in shape design applicable for Advanced Urban Transit System. Human's sensitivity and User Interface of rolling stock investigated ergonomic studies of several type. The sensibility engineering design made approach of user center design in rolling stocks design. Therefore, we have application to properly of ergonomic design element in rolling stock design. we expert visual design and user interface help greatly in excellent rolling stock design.

In this study, emotion changes were induced by four imaginations- pleasantness, unpleasantness, arousal, relaxation and it was examined using subjective evaluation and analysis of the physiological signals of the central and autonomic nerve systems whether the intended emotions were appropriately achieved, and whether these emotion changes could be distinguished from the analysis of physiological signals. Each of the four imaginations was implemented on 32 subjects for 30 seconds, while that Electroencephalogram (EEG), Eelectrocardiogram (RSP) were measured, and a subjective evaluation was implemented following the completion of the measurement. The analysis of the subjective evaluation revealed that the subjects underwent the four clearly differentiated imaginations, and the pleasantness level was classified into four imagination stages, pleasantness>relaxation>arousal=comfort>unpleasantness, and arousal level was classified into four imagination stages in the order of arousal>unpleasantness${\approx}$pleasantness>comfort>relaxation. The analysis of the EEG revealed that three stages of pleasantness level, pleasantness>relaxation=arousal=comfort>unpleasantness were classified from the values of ${\alpha}/{\alpha}+{\beta}\;and\;{\beta}/{\alpha}+{\beta}$, and about tour distinguishable stages of arousal level were obtained from the autonomic nervous system responses following the order of arousal>unpleasantness${\approx}$pleasantness> comfort> relaxation. It was found that intended emotion could be induced from the imagination, and these induced emotion changes could be differentiated using the physiological signals of the EEG and autonomic nervous system.

Objective: The aim of this study is to investigate the effect of BackJoy on how it effectively reduces the physical load generated in a posture in which the user sits, increases user's comfort and satisfaction, and maintains the correct posture. Background: Because of development of science and economic development, most office workers and students spend about 75% of their working time in chairs. However most of them have a poor posture. Method: This experiment conducted measurement using a pressure mat and surveyed to evaluate fatigue level, satisfaction and comfort of sit. The study is experimented 20 male and 14 female participants. The participants carried out four different types of tasks and each task took 20 minutes long. Results: In the case of experiment results before and after the use of BackJoy, average pressure, contact area and pressure per unit area appear to prove that using BackJoy is more effective. Conclusion: Through this study, the BackJoy's effects for the maintenance of good posture and loads that occur in the body are reduced. In the future study, there are some researches needed for various verifications using an EMG sensor that shows loads of vertebrae and we need to analyze each group of the participants by dividing them. Application: The evaluation method used in this study can be applied to evaluating ergonomic chairs.

We are exposed to the various external stimuli input from the environment, which cause emotional changes based on the characteristics of the stimuli. Unfortunately, there are no quantitative results on relationship between human sensibility and the characteristics of physiological signals. The objective of this study was to quantify EEG signals evoked by auditory stimulation based on the assumption that the analysis of the variability on the characteristics of the EEG waveform may provide the significant information regarding changes in psychological states of the subject. The experiment was devised with seven experimental conditions, which are control and six different types of auditory stimulation. Twenty subjects were used to obtain EEGs while introducing auditory stimulation. Wavelet transformation was employed to analyze the EEG signals. The results showed that the reconstructed signals at the decomposition level revealed the different energy value on the EEG signals. Also, general patterns of EEG signals in rest state compare with negative and positive stimulus were found. This study could be extended to estabilish an algorithm which distinguishes psychophysiological states of the subjects exposed to the auditory stimulation.
