Previous studies, while investigating factors of sensibility, had rarely considered its internal structure. This study hypothesized that sensibility had sensational aspects and emotional aspects and the former corresponded to objective adjectives, describing attributes of objects, and the latter to subjective adjectives, describing psychology of experiencers. Forty-three objective adjectives and 21 subjective adjectives describing color sensibility were selected both by a linguistic criterion and an empirical evaluation. Factor analysis on semantic differential responses to these two groups of adjectives resulted in 5 sensational factors and 3 emotional factors of color sensibility respectively. Hierarchical structure was derived by regressing emotional factor scores on sensational factor scores. In consequence, emotional aspects were interpreted by different combinations of sensational factors. Limitations and significance of this study were discussed.

Objective : This study examined the test-retest reliability and interrater reliability of the Sensory Processing Scale for Children (SPS-C). Method : Senventy primary caregivers of children with sensory processing difficulties and 3 years old participated in the study. The subjects were recruited through child development centers, welfare centers, and acquaintances located in Seoul, Gyeonggi-do, Busan, and Gyeongsang-do. The test-retest reliability verification targeted 20 main caregivers of children with difficulty in sensory processing. Re-evaluation was performed within 7 to 14 days after the initial evaluation, and Pearson's correlation coefficient was used to confirm the relevance between the two time points, and the Intraclass correlation coefficient was used to confirm the degree of agreement. The interrater reliability verification was conducted with 18 primary caregivers and 18 subsidiary caregivers of children with sensory processing difficulties. Each caregiver evaluated the same child, and the Intraclass correlation coefficient was used to confirm the agreement between the two sets of caregivers. Results : The test-retest reliability was Pearson's correlation coefficient r=.914 and intraclass correlation coefficient ICC=.939, indicating a high level of relevance and agreement. The interrater reliability was an Intraclass correlation coefficient ICC=.727, which showed a moderate level of agreement, but the tactile area (ICC=.455) and proprioceptive area (ICC=.439) were not statistically significant and showed a low degree of agreement. Conclusion : Through this study, it was confirmed that the children's Sensory Processing Scale for Children (SPS-C) is a stable evaluation tool with test-retest reliability and interrater reliability verified, and it will be able to provide help in standardization studies for future clinical use.

The purpose of this study was to investigate evidence-based practice (EBP) for sensory integration (SI) intervention in children with cerebral palsy (CP) through a systematic review and meta analysis. The screening strategy was performed to select studies for analysis after that, a meta-analysis was implemented for calculating the effect size (ES) in group studies. Twenty-four studies were included for a systematic review and included seven case reports, three single-subject designs, and fourteen group experimental design studies(three randomized controlled trials, three two groups nonrandomized studies, and six one group nonrandomized studies). The ES of the experimental group studies was moderate size of 0.272. The results of the ES according to the dependent variables, the ES was the largest in the fine motor development. The effect size of the published papers was greater than the unpublished paper's and two groups nonrandomized studies' size effect was the largest in the design. The ES of the infants was larger than the children. The ES for a period of 8 weeks, the number of five times a week, and time in 90 minutes showed the biggest in SI program. Although the ES of SI intervention in children with CP showed moderate effect, accumulation of research well be needed.

The purpose of this study is to derive interaction types that appear variously in immersive contents through John Dewey's empirical theory, and to explore how the derived types are delivered in real cases. For this reason, two cases of the National Museum of Korea 'Immersive Digital Gallery' and 'Arte Museum Jeju' were analyzed through interaction types derived from the empirical theory. The interaction types derived based on the experience theory are the elements of 'multi-sensory', 'simultaneous experience' and 'sensory expansion'. In both cases, these types appear connected rather than grafted one by one in common. In one direction, 'multi-sensory' leads to 'sensory expansion', and in two directions, 'simultaneous experience' leads to 'sensory expansion'. As such, the core types of communication between technology and humans are not delivered one by one, but a cycle of interaction is formed in multiple ways. Therefore, it can be seen that the interaction type of immersive contents is expanded step by step by fusion of various senses and experiences in various fields, rather than a 1:1 partial delivery method. Based on this, it will be necessary to study how types are expanded and how viewers are affected when interaction is implemented in immersive contents in the future.

Objective : This study aims to verify the validity and reliability of the Korean version of the Sensory Processing and Self-Regulation Checklist (SPSRC) for children with and without autism spectrum disorder. Methods : The Pearson product-moment correlation coefficient was calculated using Short Sensory Profile (SSP) to verify concurrent validity. Construct validity was verified by comparing the sensory processing ability and self-regulation ability of the two groups. Cronbach's α was calculated in the case of internal consistency for reliability verification, and the test-retest reliability was verified through the Pearson correlation coefficient. Results : Based on the verification of the concurrent validity, the Korean version of SPSRC and SSP showed a statistically significant correlation (p < 0.01). The construct validity was found to have a statistically significant difference between the two groups in the area and sub-items of the Korean version of SPSRC (p < 0.001). For the internal consistency, Cronbach's α ranged from 0.700 to 0.975. The test-retest reliability showed that the correlation coefficient ranged from 0.937 to 0.997. Conclusion : The Korean version of SPSRC was confirmed to be an evaluation tool with high validity and reliability. It is expected to be used as an evaluation tool for planning treatment goals in clinical trials and as a meaningful basis for future research.

The antennal receptors of the adult male and female of the American leafminer, Liriomyza trifolii (Diptera: Agromyzidae) was studied using the scanning electron microscopy. This antennal receptors were developed to accept the chemical or mechanical signal in the environment. The antennae of L. trifolii is 317.52 $\mu$m long and composed of the scape, pedicel, funicle, arista. Antennae located between compounds eye on the middle in the head. The result of SEM observation, four types of receptors were characterized and grouped into morphological classes: Trichoid, Basiconic, Coeloconic, Chetiform sensilla. Trichoid sensilla are located on the all segment. As a rule, female is more than male. This sensilla are long and slender hair with straight or slightly curved, and taper to a sharp point apically. Basiconic sensilla are observed only on the funicle. The number of basiconic sensilla in male and female are almost same in both sexes. This sensilla are long and thick hair with stright or slightly curved, and taper to a blunt point apically. Coeloconic sensilla are observed only on the funicle. This sensilla were showed a finger-like projections the peg apex. The number of basiconic sensilla in male and female are almost same in both sexes. Chetifarm sensilla are located on the all segment. This sensilla are needle-like, tapering sharply. Pedicel are more than scape. The number of Chetiform sensilla in male and female are almost same in both sexes.

The nonlinearity of hemodynamic response in the somatosensory cortex was investigated with vibrotactile stimulation. The stimuli consisted of a train of 25 Hz, each tasting five different duration periods, 2 s, 4 s, 8 s 12 s, or 16 s with 20 sec periods of no vibration in a pseudo-random order. In order to understand the linearity on the change of stimulus duration for somatosensory cortex, two different tests- checking the linearity of system and finding the impulse response function from gamma-variate function were applied to analyze the hemodynamic response functions. They have produced nearly same results. The BOLD response in the somatosensory cortex Is nonlinear for stimuli of less than 8 seconds, but nearly linear for stimuli greater than 8 seconds. The amplitude, area, TTP, and FWHM as functions of the stimulus duration were calculated and showed a significant downward trend with Increasing stimulus duration for the amplitude and the area. It supports the ranges of nonlinearity are less than 8 seconds.
