This research investigated the influences of structural characteristics such as fabrics, mechanical properties, and subjective sensory images on the off-line and on-line preferences to women's spring/summer suits fabrics to extract the most effective factor towards preference as well as analyze the preferential off-line and on-line differences to predict the exact texture image on-line. Objective evaluations were done for the measurement of the mechanical properties of fabrics using Kawabata's Evaluation System and subjective evaluations were done with 109 female subjects who value the off-line and on-line sensory image of suit fabrics. For statistical analysis, factor analysis, cluster analysis, t-test, ANOVA, and regression were used. The results were as follows. The preference scores on-line were generally higher than those off-line. For the structural characteristics of fabrics, differences of thickness were observed according to preference clusters, and the preference increased as thickness was lowered off-line and on-line. For mechanical properties, WC influenced off-line and on-line preferences. Fabrics with low compression energy were preferred; however, the effect of SMD was observed off-line only. In subjective sensory images, the 'smoothness' image influenced off-line and on-line preferences the most. All sensory images influenced the off-line preferences; however, the effects of 'flexibility' and 'weight' were not shown on-line.

Nowadays, some movie theaters provide additional sensory information in 3D movies to enhance visually induced motion perception. However, no studies have investigated how motion perception increases. Thus, in this study, we examined the effect of visual coherent sensory information on visually induced motion perception and quantification of sensory information. A visual stimulus rotated sinusoidally and visual coherent sensory information were applied as vibrations to a subject's foot. We measured the sway of the subject's body by using a force plate and somatosensory bar rotation that represents the subject's perception of the horizon using an encoder. By using this data, we obtained the weight of the sensory information using a Kalman filter. As a result, it was found that subjects rotated the somatosensory bar more when visual coherent vibrations were applied. The weight of vision also increased when visual coherent vibrations were applied. Thus, we can conclude that visual coherent sensory information tends to enhance visually induced motion perception and weight of vision.

Background: Mild cognitive impairment (MCI) is also called as aging related memory damage. Decreased cognitive function due to aging is known to be associated with the frontal lobe. Alpha wave is generated in the dominance in the frontal lobe or a wide range of regions in the brain, it should be doubted that the brain function might be degraded. Objective: To determine the effect of sensory stimulation type on learning and brain activity pattern of elderly persons with MCI. Design: Randomized Controlled Trial (single blind) Methods: Twenty elderly persons aged more than 65 with MCI were randonmized to simultaneous visual/auditory stimulation group (SVASG) and or auditory stimulation group (ASG). Ten peoples were assigned to each group and lectroencephalogram test was performed to individuals. In the electroencephalogram test, electroencephalography of prior to sensory stimulation, and during sensory stimulation were measured to compare brain activity pattern according to the study groups and measurement period. Results: The relative alpha power due to a sensory stimulation type showed that the SVASG significantly decreased in the left frontal lobe and the left parietal lobe statistically compared to those of the ASG while sensory stimulation was given (p<.05). The relative beta power due to a sensory stimulation type showed that the SVASG significantly increased in the left and right frontal lobes, the left and right parietal lobes, and the left temporal lobe statistically compared to those of the ASG while sensory stimulation was given (p<.05). Conclusions: Electroencephalographic analysis showed that the type of sensory stimulation can affect the brain activity pattern. However, the effects were not studied that which brain activity pattern help to improved cognitive function of elderly persons with mild cognitive impairment.

Purpose : This study is to investigate the modulatory effects to the ultraviolet induced erythema of pain processing system. Methods : Thirty six healthy volunteers were divided into none treatment group (n=6), indomethacine group (n=6), subsensory level electrical stimulation group (n=6), sensory level electrical stimulation group (n=6), motor level electrical stimulation group (n=6), noxious level electrical stimulation group (n=6). Subjects were induced erythema for three times minimal erythema dose (MED) at upper arm of dermatome C6 level. Each experimental group had mechanical pain threshold (MPT), electrical pain threshold (EPT), thermal pain threshold (TPT). Results : This study revealed that we observed that pain thresholds were significantly correlated with each other in pain processing system. The effect of electrical stimulation levels evaluates were shown to be significant differences pain control effect in electrical stimulation group (sensory, motor level electrical stimulation groups) more than indomethacine group, subsensory level and control group. Conclusion : In this study, it was found that the effect of ultraviolet induced erythema of pain control by modulatory electrical stimulation.

Capsaicin, a pungent ingredient in chili pepper, is known to excite sensory neurons that mediate pain sensation. This effect of capsaicin is determined by unique receptors and the capsaicin receptor (transient receptor potential subfamily V, member 1 (TRPV1)) was cloned recently. TRPV1 contains six transmembrane domains and three ankyrin repeats at N-terminal. This characteristic architecture is common in other ion channel in TRPV families. (omitted)

When one sensor cannot provide information by sensory deficit or loss, the sensory information can be provided by substituting other sensors for the defected sensor. This sensory substation might be influence on the deteriorated motion perception that consists of multi-sensory information such as visual, vestibular and somatosensory information. In this study, to investigate whether the additional sensation by sensory substitution could be integrated into the motion perception, we examined the effect of substituted postural sway sensation on the directional perception of body movement. Deteriorated motion perception by the reduced plantar sensation was enhanced under sensory substitution condition that provided the body sway information as the plantar vibratory stimulus. These results imply that the additional sensation might be integrated into and improve the motion perception.

Digital information society shows a variety of contents of cross-categorial digital media in their inner or outer forms and concepts of the artistic aspects. In order to cope with such a complicated, unexpected trend in digital media and its industry, a new approach in the design process needs to be developed and adjusted with the new equipment of the creativity-thinking process of 'the Multi-Sensory Device (MSD),' 'the Multi-Dimensional Device (MDD),' and 'the Storytelling Device (SD)' in the Prism Effect-based Creativity-Thinking Process (PECTP). The PECTP is in principle designed to practically work with the four distinct techniques: 1) Physical Activity, 2) Linguistic Activity, 3) Visual Activity, and 4) Complex Activity. Consequently, this thesis notes that the nature of the cross-categorial design contents is necessarily non-directional since the creativity power inside the Prism Effect results in openness and diversity.

Objective : This study aims to figure out the effect that sensory integration group therapy has on the fine motor, social interaction and playfulness of preschool children with intellectual disability. Methods : Participants were four children from three to five years old who were diagnosed with intellectual disabilities and they participated in twelve sessions of sensory integration group therapy, sixty minutes per session and once a week. Sensory integration group therapy was composed of parallel and peer play-centered gross motor activities, art activities and sensory plays that were related to each theme. Erhardt Developmental Prehension Assessment (EDPA), Penn Interactive Peer Play Scale (PIPPS) and Test of Playfulness (ToP) were used to evaluate participants' fine motor, social interaction and playfulness before and after the intervention. Results of fine motor, social interaction and playfulness before and after the intervention were compared using Wilcoxon matched-pair signed rank test. Results : After sensory integration group therapy intervention, the fine motor skills of participants did not show significant increases, but social interaction and playfulness showed significant increases (p< .05). Conclusion : Although sensory integration group therapy with preschool children with intellectual disability did not show positive improvement in fine motor skills, it showed positive effect on social interaction and playfulness. Group sensory integration therapy might be an intervention approach for all children with disabilities.

Objective : The aim of this study is to verify the effects of group sensory integrative intervention for sensory motor ability, behaviors in children with developmental delay. Method : The subjects were five children with developmental delays aged between 3 and 5. All Children participated in 26 sessions of group sensory integrative intervention. Children' behavior during testing was observed to assess the sensory motor ability, behaviors, the clinical observation. One group pretest- posttest design was used to verify the effect of group sensory integrative intervention. The observed children' behavior during testing were tested by the Wilcoxon matched-pair signed rank test. Results : There is no significant difference in the clinical observation between pre and post intervention. However, subjects showed the significant difference in Social interaction(Z=-2.121, p=.034), Attention(Z=-2.032, p=.042), total score in Behavior during testing(Z=-2.032, p=.042). Conclusions : The result in this study suggested that the sensory integrative intervention is effective in facilitating the social skills and improving the attention and behaviors. On the other hand, there is no effect in sensory motor ability. It is difficult to generalize the conclusion because the number of the subject was limited and the environmental confounding factors has not been controlled. Therefore, it is needed to supplement these limitations in the future study.

Objective : The purpose of this study was to investigate the effects of paired-group sensory integration therapy on sensory processing, peer interaction, and play development of four-year-old children. Methods : This study involved 13 weekly sessions of a four-minute intervention as well as an initial 10 minutes of parental counseling for those without experience of paired-group sensory integration therapy. The intervention consisted of sensory processing activities and various occupational activities, and the children's Short Sensory Profile (SSP), Penn Interactive Peer Play Scale (PIPPS), and Knox Preschool Play Scale-Revised (KPPS-R) were measured before and after the sessions for comparison. The results are presented using visualized data. Results : After the paired-group interventions, all subjects showed improved sensory processing ability according to their SSP scores and improved play development on the KPPS-R. Moreover, the frequency of negative interactions decreased in the PIPPS measure. Conclusion : This paired-group sensory integration therapy had a positive effect on sensory processing, peer interaction, and play for children with developmental delay. In the future, research that applies this kind of paired-group intervention in various age groups would be useful.
