Objective : This study is to verify effect of a sensory integration (SI) intervention on sensory processing of children with sensory modulation disorder (SMD), and to explore how the SI intervention affect play, socialization, occupational performance and occupational satisfaction of those children. Method : Five children with developmental disabilities living in metropolitan were diagnosed as SMD by the Sensory History Interview (SHI) and Short Sensory Profile (SSP). The SMD children undergone the 48 sessions of 50 min intervention twice in a week for six months and took the Revised Knox Preschool Play Scale(RKPPS), Social maturity test, Canadian Occupational Performance Measure(COPM), and Japanese Sensory Inventory Revised(JSI-2) before- and after the intervention. The result data analyzed by the Wilcoxon matched-pair signed rank test. Results : All data of post-intervention differed significantly; RKPPS(Z=-2.023, p=.043), Social maturity test(Z=-2.023, p=.043); occupational performance(Z=-2.023, p=.043); satisfaction(Z=-2.032, p=.042); and tactile system of JSI-2(Z=-2.032, p=.042). Conclusions : The results advocate that sensory integration intervention is effective in improving tactile processing, play, socialization, occupational performance, and occupational satisfaction of child with SMD. It is found that sensory integration intervention improves not only one's occupational performance but also underlying components of the performance. In order to generalize this conclusion, further studies need to be done with more number of subjects and consideration of environmental factors. Striving for more reliable and valid methods of data collection is also suggested.

The aim of this study is to look into the meaning and sub-factors of spatial orientation, compare and analyze mathematics curriculums and textbooks of several countries with respect to spatial orientation and offer suggestions to improve teaching spatial orientation in elementary school mathematics in Korea. In order to attain these purposes, this study examined the meaning and sub-factors of spatial orientation through the theoretical consideration regarding various studies on spatial sense. Based on such examination, this study compared and analyzed mathematics curriculums and textbooks used in South Korea, Singapore, Japan, China, Hong Kong, Finland, United States of America, and Germany with respect to contents of mathematics curriculum and textbooks in grades, sub-factors of spatial orientation, and contexts for spatial orientation. In the light of such theoretical consideration and analytical results, this study provided suggestions for improving teaching spatial orientation in elementary schools in Korea as follows: extending content of spatial orientation in mathematics curriculum, emphasizing spatial orientation across the several grades, especially in the upper grades, providing opportunities to learn the sub-factors of location, direction, coordinates, route, and distance variously, and utilizing various familiar and realistic contexts in the world around students.

The lower limb somatosensory deficit observed among peripheral neuropathy patients is partially related to the decline in their balance ability. In general, balance ability has been examined by measuring the postural response (i.e., action). However, body motion is induced by integrated multisensory cues (i.e., motion perception). In this study, we hypothesized that the reduced lower limb somatosensation might also lower motion perception. We induced lower limb sensory deficits through ischemia and then measured the cutaneous sensory sensitivity and directional motion perception. The sensory deficit was successfully induced, and it also lowered the motion perception. However, the center of pressure (COP) variation did not significantly change under the sensory deficit. This result implies that measuring motion perception could enable the detection of precursors of sensory deficits.

This paper focuses on a real-time hardware processing by implementing the ARM Cortex-M4 based embedded system, using a conversion algorithm from a muscular sense to both visual and auditory elements, which recognizes rotations of a human body, directional changes and motion amounts out of human senses. As an input method of muscular sense, AHRS(Attitude Heading Reference System) was used to acquire roll, pitch and yaw values in real time. These three input values were converted into three elements of HSI color model such as intensity, hue and saturation, respectively. Final color signals were acquired by converting HSI into RGB color model. In addition, Three input values of muscular sense were converted into three elements of sound such as octave, scale and velocity, which were synthesized to give an output sound using MIDI(Musical Instrument Digital Interface). The analysis results of both output color and sound signals revealed that input signals of muscular sense were correctly converted into both color and sound in real time by the proposed conversion method.

People tend to perceive their loved others (e.g., children, spouse, romantic partner) as their extended selves and then control over the loved others' fashion style corresponding to their self-concept. The study conceptually suggested that people's perceptions on legitimacy to interfere the others and their own fashionability would separately or interactively influence their control over the loved others' fashion style. To investigate the suggestions, an experiment with female participants in their 20's was conducted by using a scenario. The results indicated that participants' perception of legitimacy to interfere their boyfriends or their own fashionability did not have a separate effect on control over their boyfriends' fashion style. However, the legitimacy and the fashionability did have an interactive effect on the control. In particular, for high legitimacy groups, there was no difference in the control between low and high fashionability groups. For low legitimacy groups, the control was stronger in high fashionability group than in low fashionability group.

This study aims to analyze the factors that affect quality of life and sensory processing abilities in older adults. Participants were 121 older adults aged over 65. Quality of life was evaluated with Life satisfaction Index for the Elderly and sensory processing abilities were measured with Korean-AASP. Korean Activiy Card Sort was utilized to assess their activity level. Low positive correlations were found between quality of life and activity level in total score(p<.01), IADL(p<.05), leisure(p<.01), and social participation(p<.01). Correlation coefficients between quality of life and sensory processing abilities showed low negative correlations in low registration(p<.01), sensory sensitivity(p<.01), and sensation avoiding(p<.01), however, there were low positive correlations in sensation seeking(p<.05). The importance of sensory processing was highlighted from the findings of statistically significant correlations between quality of life and sensory processing abilities. This indicates that improvement of sensory processing abilities is critical in occupational therapy service for older adults. Furthermore, the findings of close relationship between activity levels and sensory processing abilities need to be reflected in senior welfare policy.

This study suggests multisensory interaction techniques to help visually impaired people appreciate and understand artworks through non-visual senses such as tactile, auditory, and olfactory senses. A user study was conducted on the basis of a qualitative interview about the experience of appreciating artwork through the multisensory interaction system to visually impaired people so as to verify the development of the interaction techniques. The user test shows that the multisensory interactions in artwork generally not only help them appreciate and understand it but also give them satisfaction through artwork appreciation. However, it also indicates that some multisensory interactions caused the visually impaired people confusion and could not be perceived during the appreciation. On the basis of these outcomes, implications in this study are as follows. This study has contributed to providing specific development guidelines and indicators of non-visual multisensory interactions as a technical alternative to improve accessibility to cultural and artistic activities for the visually impaired. Furthermore, this study is expected to contribute to building a technical background, which can provide comprehensive sensory experiences with not only blind people but also non-blind people such as children and the elderly through universal interaction techniques beyond existing visual-oriented fragmentary experience.
