Objective : The purpose of this study was to analyze the effects of multisensory exercise on foot pressure sensitivity and balance for the elderly. Method : The subjects were 17 elderly women (11 for the experimental group and 6 for the control group) with a mean age of 83. The subjects all lived in senior residence centers in Seoul. Multisensory exercise was done twice a week for 40 minutes during a 12 week period. Exercise programs were changed every 3 weeks according to the principal of gradual progress of the exercise. In order to train the vision system subjects were asked to open and close their eyes during exercise. When it came to training the vestibular system, subjects stood and walked on high elastic mats with their bare feet. For the somatasensory system subjects always stood and walked with their bare feet. The sub-Metatarsal Pad Elasticity Acquisition Instrument (MPEAI) was used to measure foot pressure sensitivity. MFT Balance test (V1.7) was used to measure anterior / posterior and medial / lateral directional balance. For the statistical analysis the IBM SPSS 21.0 was used to perform Repeatde measured ANOVA and Wilcoxon ranked test. Results : For the multisensory exercise group Hallux (after 6 weeks, 12 weeks), heel (after 6 weeks) and 2nd Metartarsal $40^{\circ}$ (after 6 weeks) pressure sensitivity increased statistically, but the control group didn't change. Also, balance didn't change for the experimental and control group statistically. Conclusion : Exercise with bare feet on a high elastic mat had a partially positive effect on foot sensitivity.

This paper proposes healthcare bathing system for improving the multisensory function and not washing. We designed various types of bathtub for developing bathing system. This system consists of whirlpool bathtub for multisensory stimulation, a cover of bathtub with visual-auditory stimulation function, a small size PC for main control, touch panel, digital multimedia broadcasting (DMB), color-changeable LED mood lighting system for improving visual sensibility and speaker. We investigate the effects on autonomic nervous system during bathing with healthcare bathing system for improving the multisensory functions. To analysis physiological parameter, body temperature, blood pressure, intraocular pressure and heart rate variability (HRV) were measured before, during and after bath using healthcare bathing system. Experiments were performed on partial immersion bath and the water temperature was kept $39{\pm}0.5^{\circ}C$. The body temperature and the heart rate variability of the subject were measured every 5 minutes before, during, and after the bath. In analysis of HRV, the parasympathetic nerve increased from starting bath and decreased after 15 minutes. So the subjects felt comfortable at 15 minutes after starting bath. Blood pressure decreased to 16mmHg maximumly however pulse increased. Bath using healthcare bathing system for improving the multisensory functions affects positively the circulation of the blood. From this results, it leaves something to be desired in evaluation of serviceability and physiological analysis using the healthcare bathing system, however, we expect to analyze more clearly the relationship between the serviceability of product, physiological change and sensibility by various physiological parameters.

In this study, we introduced the technique of matching classical music using deep learning to design soundscape that can help the viewer appreciate painting and proposed an evaluation index to evaluate how well matching painting and music. The evaluation index was conducted with suitability evaluation through the Likeard 5-point scale and evaluation in a multimodal aspect. The suitability evaluation score of the 13 test participants for the deep learning based best match between painting and music was 3.74/5.0 and band the average cosine similarity of the multimodal evaluation of 13 participants was 0.79. We expect multimodal evaluation to be an evaluation index that can measure a new user experience. In addition, this study aims to improve the experience of multisensory artworks by proposing the interaction between visual and auditory. The proposed matching of painting and music method can be used in multisensory artwork exhibition and furthermore it will increase the accessibility of visually impaired people to appreciate artworks.

Behavioral studies of emotion recognition in autism spectrum disorders (ASD) have yielded mixed results. Most of the studies focused on emotion recognition abilities with regard to ASD using stimuli with unisensory modality, making it difficult to determine difficulties in real life emotion perception in ASD. Herein, we review the recent behavioral and cognitive neuroscience studies on emotion recognition functions in ASD, including both unisensory and multisensory emotional information, to elucidate the possible difficulties in emotion recognition in ASD. In our study, we discovered that people with ASD have problems in the process of integrating emotional information during emotion recognition tasks. The following four points are discussed: (1) The restrictions of previous studies, (2) deficits in emotion recognition in ASD especially in recognizing multisensory information, (3) possible compensation mechanisms for emotion recognition in ASD, and (4) the possible roles of attention and language functions in emotion recognition in ASD. The compensatory mechanisms proposed herein for ASD with regard to emotion recognition abilities could contribute to a therapeutic approach for improving emotion recognition functions in ASD.

Purpose: The purpose of the study was to examine the effects of multisensory stimulation (MSS) using familiarity on persons with dementia (PWDs) residing in nursing homes in Korea. Methods: A nonequivalent control group with pre and posttests was used. Fifty one PWDs were included if they: 1) were over 65 yr old, 2) were diagnosed with dementia, 3) had no visual or speech impairments, 4) were able to communicate, and 5) had spent more than one month in a nursing home. The experimental group (n=25) received a 55 min MSS program twice a week for 10 weeks. The outcome variables included were cognition, activities of daily living, grip strength, depression, wandering, and aggressive behaviors. Repeated ANOVA was used for data analysis. Results: There were no significant differences in demographics or the main variables at pretest. Cognition, depression, wandering, and aggressive behaviors were significant over time between the two groups. Grip strength was only significant when accounting for interaction between group and time. Conclusion: An intervention of MSS using familiarity was marginally effective in improving cognition, depression, wandering, and aggression. Future study is suggested with a larger sample and longer treatment to retest the effects of MSS.

Purpose: This paper aims to investigate whether consumers' mental simulation and self-brand connections influence purchase intention and how the characteristics of advertisings' nonverbal information (congruence among multisensory cues) and verbal messages (self-referencing point and narrative structure) jointly shape mental simulation and self-brand connections. Research design, data and methodology: This paper develops a sportswear advertising and totally collected 225 data through the online survey platform "WenJuanXing". To exam the hypotheses in this paper, structural equation model is conducted in AMOS 21.0 via using 210 valid data. Results: The findings reveal that consumers who engage in mental simulation or establish the connections between them and the brands are more likely to present high purchase intention. Moreover, the characteristics of congruence among multisensory cues, self-referencing points and narrative structure can not only facilitate consumers' mental simulation but also encourage consumers to create connections between them and the brands. Conclusions: This paper develops the advertising research via exploring the characteristics of advertisings' nonverbal information (multisensory cues) and verbal messages simultaneously. And suggesting that both of consumers' mental simulation and self-brand connections are the important approaches for advertisers to effectively increase consumers' purchase intention. Finally, the limitations and suggestions are concluded for the future research.

Purpose: The aim of this research was to investigate the effects of self-sit-to-stand training on balance ability and sit-to-stand ability in hemiplegic stroke patients using a multisensory feedback device. Methods: A total of 19 stroke patients participated in this study, and they were divided into two groups: 10 underwent self-sit-to-stand training using a multisensory feedback device, and 9 underwent sit-to-stand training with a physical therapist. In both groups, sit-to-stand training was performed for 30 min, 3 times a week, for 6 weeks. The subjects also underwent physical therapy twice a day for 30 min, 10 times a week, for a total of 60 sessions. Balance ability was evaluated using the AFA-50 and Berg Balance Scale. Sit-to-stand ability was evaluated using the five times sit-to-stand test. Results: Sway length, pressure, and total pressure all significantly increased in both groups, and there was no difference between the two groups. The Berg Balance Scale results showed that balance ability significantly increased in both groups, and there was no difference between the two groups. The five times sit-to-stand test results showed that sit-to-stand ability significantly increased in both groups, and there was no difference between the two groups. It was found that the self-sit-to-stand training using a multisensory feedback device had a positive effect on balance control and sit-to-stand ability. When the two groups were compared, no difference in balance ability or sit-to-stand ability was observed. Conclusion: The findings of this study indicate that self-sit-to-stand training using a multisensory feedback device is as effective as sit-to-stand training with a physical therapist. Hence, self-sit-to-stand training using a multisensory feedback device could be an effective home-based exercise protocol for hemiplegic stroke patients to improve their balance and sit-to-stand abilities.

A decentralized control method is proposed to enable a group of robots to achieve maximum performance in multisensory target tracking while avoiding collision with the target. The decentralized control was designed based on navigation function formalism. The study showed that the multiple agent system converged to the positions providing the maximum performance by the decentralized controller, based on Lyapunov and Hessian theory. An exemplary simulation was given for a multiple agent system tracking a stationary target.
