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.

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 : This study was to investigate the relationship between sensory processing patterns and sleep quality for poor sleepers enrolled in universities. Methods : The participants are 191 students, aged 18 to 25, at the 6 universities located in Busan, Daegu, and other Gyeongsang Provinces. These participants completed the Korean version of Adolescent/Adults Sensory Profile (AASP) and the Pittsburgh Sleep Quality Index (PSQI). Results : The group with lower sleep quality of this study participants suggested low but positive correlation with sleep disturbance which is one of sleep quality components of the PSQI. Low sensory registration suggested high positive correlation and Sensory sensitivity suggested low positive correlation with daytime dysfunction. Conclusion : We identified that sensory processing patterns and sleep quality may influence each other and sleep quality can be more significantly influenced by specific sensory processing pattern. More studies requires on sleep quality and sensory processing patterns in children, adults, and elders.

Objective : The purpose of this study is to summarize the best-available intervention evidence for children's sensory integration therapy, drawn from studies published domestically in Korea over the last 10 years. Methods : The articles evaluated in this study were collected from the RISS and DBpia databases using the search terms "sensory integration," "sensory processing," and "Ayres Sensory Integration (ASI)". A total of 19 papers were analyzed. The selected studies were then assessed using the Population, Intervention, Outcomes, and Comparison method, the International Classification of Functioning, Disability and Health (ICF) method, and the modified Evidence Alert Traffic Light Grading System. Results : Development delay was the most commonly applied diagnosis for children's sensory integration therapy and individual sensory integration therapy was the most frequently used intervention method. The intervention effect was 91 percent in the body structure and function of ICF. The areas concentrated on were sensory modulation, sensory processing, fine and gross motor, body scheme, body-self concept, balance, basic movement, postural control and hand function, attention, and self-esteem. Conclusion : This simple overview of the efficacy of children's sensory integration therapy provides a basis for easy understanding and use by therapists, researchers and families with children.

Objective : The purpose of this research is understanding relevancy of school ages'ability of sensory process and preference of what they want to play, and studying of main reason of impact of sensory process to preference of what school ages want to play. Methods : During 22 to 24 October 2012, our group evaluated and analyzed ability of sensory process and preference of what children want to play by using Short Sensory Profile (SSP) and Pediatric Interest Profile (PIP) to elementary school children in fourth grade at Kimhae city in Kyungnam province. Results : For the total population of an ability of sensory process and frequency, preference, and proficiency of eight different games, preference of outdoor activities appears to be related to total score of sensitivity to taste and smell and filter of hearing. For preference and proficiency of creative activities appears to be related to sensitivity of taste and smell. Preference of lessons and classes related to total scores of sensitivity of tactile sensation, taste and smell, movement, and filter of hearing, and sensitivity of visual and hearing. Frequency and proficiency of lessons and classes are inter-related to sensitivity of visual and hearing. Conclusion : This research shows that there is no inter-relationship between function of sensory process and preference of what children want to play, however certain games relevantly show the inter-relationship. The research provides the basic data of what the preference of what children want to play and determine what children can play during occupational therapy with plays after studying inter-relationship of school ages'ability of sensory process and games.

Objective : The aim of this study was to provide mechanism information of a link between arousal and sensory modulation to increase understanding of neurophysiological study. Subject : Optimal arousal state of a child is an important issue in sensory integration therapy. Limbic system and reticular formation are related to sensory modulation by sensory input. Sensory inputs processes from reticular formation to cortex via ascending reticular activation system for moderate arousal. A lot of neurotransmitters such as cholinergic neurons and monoamin neurons help this processes. Mechanism of arousal was measured by functions of central nervous system (CNS) and autonomic nervous system (ANS) using objective tools such as an electroencephalogram (EEG) and electrodermal responses. Functions of CNS and ANS showed differences between normal children and children with disabilities. Optimal sensory input using sensory integration therapy for children with disabilities helps to act reticular formation, limbic system, and cortex and to maintain appropriate arousal. Conclusion : Such quantitative studies by using neurophysiological methods provide evidence for sensory integration therapy.

Food is crucial for the nutrition and survival of humans. Taste system is one of the fundamental senses. Taste cells detect and respond to five basic taste modalities (sweet, bitter, salty, sour, and umami). However, the cortical processing of taste sensation is much less understood. Recently, there were many efforts to observe the brain activation in response to taste stimulation using functional magnetic resonance imaging (fMRI), magnetoencephalography (MEG), and optical imaging. These different techniques do not provide directly comparable data each other, but the complementary investigations with those techniques allowed the description and understanding of the sequence of events with the dynamics of the spatiotemporal pattern of activation in the brain in response to taste stimulation. The purpose of this study is the understanding of the brain activities to taste stimuli in sensory and affective aspects and the reviewing of the recent research of the gustotopic map by functional brain mapping.
