Purpose : Adolescent/Adult Sensory Profile is the questionnaire to evaluate sensory processing based on daily activities. Self-questionnaire commonly tends to be biased to the characteristics of subject, so its validity is low. This study aims to analyze correlation between questions of Adolescent/Adult Sensory Profile and tactile threshold measured from cognitive behavioral experiment. Methods : The tactile threshold was calculated by tactile detection task and tactile stimuli were provided with the consistent current stimulator. The tactile threshold was compared with results of tactile processing items in Adolescent/Adult Sensory Profile and statistical correlation analysis was performed. Results : Scores in Low Registration and Sensation Seeking had positive correlation with the tactile threshold and scores in Sensory Sensitivity and Sensation Avoiding had negative correlation with the tactile threshold. Among them, only Low Registration was statistically significant. Conclusion : The questions in Low Registration(Tactile Processing)are highly correlated with physiological characteristics. As a result, it was shown that sensory inflow is less, if the tactile threshold is high.

Objective : The aim of this study was to investigate the relationship between interoceptive awareness, sensory processing, and heart rate variability which reflects the function of the autonomic nervous system. Methods : Young adults completed the Adolescent/Adult Sensory Profile (AASP) and the Multidimensional Assessment of Interoceptive Awareness (MAIA) for sensory processing and interoceptive awareness, respectively. Heart rate was recorded using electrocardiograms during the resting period, and the standard deviation of normal-to-normal interval (SDNN) was extracted. The correlation between sensory sections of the AASP and subscales of the MAIA was analyzed, and the differences in touch and interoceptive awareness between groups with high and low SDNN were compared. Results : The touch of the AASP showed a relatively strong correlation with the subscales of the MAIA. Higher touch scores were associated with lower scores of not-worrying and attention regulation, but higher emotional awareness. The high SDNN group showed a tendency of higher interoceptive awareness compared to the low SDNN group. Conclusion : This study demonstrated the tactile processing has the relationship with interoceptive awareness and individuals with higher heart rate variability tend to have greater interoceptive awareness. This study provides information on interoceptive awareness, which is emphasized in recent occupational therapy and sensory integration practices, and deepens the understanding of neurophysiological mechanism of sensory integration.

감각대체기술은 손상된 감각 정보를 다른 감각으로 전환하여 전달하는 기술로써 기존의 시각장애인을 위한 시각 정보의 촉각 대체 기술은 주로 거리 정보나 물체의 윤곽선 정보를 전달하여 사용자가 주변 환경을 이해하는 데 어려움이 있었다. 이를 해결하기 위해 본 논문에서는 딥러닝을 사용하여 사용자 주변의 모션 정보를 분석하고, 이를 촉각 정보로 전달함으로써 사용자가 주변 상황 정보를 인지 할 수 있는 방법을 제안하였다. 제안 방법과 기존의 윤곽선 정보 전달 방법을 사용자 실험을 통하여 비교하였을 때, 제안 방법이 영상 속 물체의 움직임 정보를 이해하는 데에 더욱 효과적임을 확인하였다.

Problems in feeding habits could affect various aspects of children including growth, learning, communication, interaction with other children, etc. Oral consumption was defined as a participant opening his/her mouth, accepting food/liquid, and swallowing. A goal of the study is to find a method of evaluation and intervention of a child's feeding habits. Feeding is an important component in the early development of children and may have later consequences in the child's ability to participate successfully in their activities of daily life. Children show personal difference on the foods which they try first because stimuli from the foods are revealed as a mealtime behavior through sensory registration and processing. Feeding problems in sensory processing consist of tactile oversensitivity, oral refusal, tactile undersensitivity, and oral dyspraxia. In order to identify problems of sensory processing among feeding difficulties and plan intervention, the understanding of neurological processing and sensory processing characteristics related to feeding is necessary. Reviewing intervention for feeding problems related to sensory processing is required for an effective approach for feeding and providing better life for children.

Objective : Multisensory integration (MSI) is the essential process to use diverse sensory information for cognitive task or execution of motor action. Especially, visual and somatosensory integration is critical for motor behavior and coordination. This study was designed to explain spatial and temporal characteristics of visual and somatosensory integration by neurophysiological research method that identifies the time course and brain location of the SI process. Methods : Electroencephalography (EEG) and event-related potential (ERP) is used in this study in order to observe neural activities when integrating visual and tactile input. We calculate the linear summation (SUM) of visual-related potentials (VEPs) and somatosensory-related potentials (SEPs), and compared the SUM with simultaneously presented visual-tactile ERPs(SIM) Results : There were significant differences between the SIM and SUM in later time epochs (about 200-300ms) at contralateral somatosensory areas (C4) and occipital cortices (O1&O2). The amplitude of the SIM was mathematically larger than the summed signals, implying that the integration made some extra neural activities. Conclusion : This study provides some empirical neural evidence of that multisensory integration is more powerful than just combing two unisensory inputs in the brain and ERP data reveals neural signature relating to multisensory integrative process. Since this study is preliminary pilot study, larger population and criteria are needed for level of the significance. Further study is recommended to consider issues including effect of internally-driven attention and laterality of interaction to make the evidence by this study solid.

Objective : The purpose of this study was to compare the effects of the sensory processing characteristics of parents of developmentally delayed children and parents of typically developed children on parenting stress. Methods : From July to August 2022, 61 parents of children with developmental delays and 64 parents of children with typical development who used occupational therapy services at pediatric clinics and child development centers were evaluated for parenting stress and sensory profiles. Results : In a multiple regression analysis on the effect of sensory processing characteristics on the total score of parenting stress, tactile processing (β = 0.353, p = 0.001), gender (β = 0.438, p = 0.000), and monthly income (β = -0.261, p = 0.014) significantly affected the parenting stress of the parents of children with developmental delay. In parents of typically developing children, tactile processing (β = 0.376, p = 0.002) and gender (β = -0.264, p = 0.024) were found to have a significant effect on parenting stress. Conclusion : Parental gender and tactile processing characteristics of developmentally delayed and typically developing children are significant influencing factors for parenting stress.

여러 분야에서 다양한 목적으로 인간처럼 생각하는 시스템을 구현하고자 하는 연구가 이루어지고 있다. 인간의 뇌에서 기억을 담당하는 부분은 시각, 청각, 촉각 등의 감각 정보를 이용하여 새로 들어온 정보가 이미 기억된 정보와 같은가를 비교하여 기존 기억에 적용시키거나 새로운 정보로 기억시킨다. 기존의 모델은 ART를 사용하여 그것을 구현하고 반복 학습되지 않는 정보는 잊혀져 버리는 것과 강한 자극과 함께 입력된 정보는 반복 학습되지 않아도 잊혀지지 않는 것이었다. 그 모델을 이용할 경우 모든 감각에 대한 정보들이 전부 한 번에 처리되었기 때문에 감각별로 정보를 차등적으로 조절하여 처리하기가 곤란하였다. 본 논문에서는 이 문제를 개선하기 위해 기존의 ART를 이용한 모델에서 감각 정보를 비교하는 과정을 퍼지 규칙을 도입한 방법으로 교체하고자 한다. 우선 입력받는 감각 정보의 여러 값들을 감각 별로 그룹화 한 후 그룹별로 퍼지 규칙을 이용하여 비교한다. 기억된 정보들을 퍼지 규칙으로 하고 입력된 정보를 이용하여 각각의 규칙에 대한 결과를 낸다. 이 모델에서는 퍼지를 사용하여 기억된 정보에 대한 이해가 쉽고, 기억된 정보를 이용할 때 규칙을 조절하여 적용하는 것으로 상황에 따라 필요한 감각 정보를 알맞게 적용할 수 있을 것이다.

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.
