Objective : This study aimed to create a Korea translation of the Evaluation in Ayres Sensory Integration (EASI) and to then test the adapted version for construct validity. Methods : The translation and content validation process were conducted in accordance with a four-step process, namely translation, integration, content validity examination, and backward translation. The construct validity of the translated version was evaluated using the EASI for children aged 3~12 years with and without sensory integration problems, comparing the two groups as well as preschool and school-aged groups. The group comparison was analyzed using the Mann-Whitney U test in SPSS. Results : In terms of content validity, all 20 items averaged more than 3.17 points. Of the four EASI categories, there was a difference in Sensory Perception (p=0.044) between the typical and sensory integration groups, and there was a statistical difference between tactile and vestibular sensations. Between the preschool and school-aged children, statistical difference was observed in two categories, namely Praxis and Ocular-Postural-Bilateral Motor Integration. Conclusion : Based on its construct validity, the Korean version of EASI is suitable for use in research. The construct validity study highlighted items that explain differences between typical and diagnostic children and items that explain those differences by age. Our findings could therefore be considered when interpreting EASI results.

The purpose of this research was to examine the subjective evaluation of sensory images and preferences according to the mechanical properties of linen and ramie fabrics for summer shirts. 54 male and female teachers evaluated the sensory images and preferences of 6 specimens of linen and ramie fabrics sold on the market. For statistical analysis, factor analysis, Mann-Whitney and Kruskal-Wallis test, Pearson correlation, and regression were used. The results were as follows: The sensory images of shirt fabrics were classified into 5 factors: 'smoothness', 'stiffness', 'elasticity', 'dry/coolness', and 'wetness'. There were partially significant differences by the gender and age in the sensory images for the shirt fabrics. Females were more sensitive than males for the 'stiffness', 'elasticity', and 'wetness' factor and the evaluators in their 20's felt fabrics were stiffer. The sensory images showed many correlations with the mechanical properties of fabric mostly. The preferences of tactile and purchase were no different according to the gender and age. They preferred a thin and soft sensory image as like ramie/cotton blended fabric and bamboo fabric for summer shirts. The significant sensory image factors affecting tactile preference were 'smoothness', 'dry/coolness', and 'elasticity', and the ones affecting purchase preference were 'smoothness', 'stiffness', 'dry/coolness', and 'elasticity'. W, WT, MMD, and G properties of the mechanical properties of fabrics affected the tactile preference for summer shirt fabrics.

Multi-sensory systems, including the visual, somatosensory, and vestibular ones, are involved in maintaining standing balance. The organization of these sensory systems is as important as the efficiency of each individual system in maintaining optimal balance. The purpose of the present experiment was to investigate the developmental changes in static standing balance and sensory organization under altered sensory conditions. This study involved 64 children (from 4 to 15 years of age) and 17 young adults. The children were divided into four age groups: 4~6, 7~9, 10~12, and 13~15 years. Static standing balance was assessed with the one-leg standing test under four different sensory conditions: the children stood on a firm surface with (1) eyes open or (2) closed, and they stood on a foam surface with eyes (3) open or (4) closed. In balancing ability, the age groups exhibited significant differences. The function of sensory organization for balance control was poorer for the children than for the young adults. The functional efficiency of the somatosensory system of the children aged 7~9 years was at the young adults' level, and the visual function of the children aged 10~12 years had also reached the young adults' level. However, the functional efficiency of the vestibular system of children was significantly lower than that of the young adults, even at the age of 15 years. This may indicate that sensory organization and standing balance are still developing after the age of 15 years.

Acute autonomic neuropathy is a rare disease. Since the first case was reported by Young et.al., in 1969, a number of similar cases have been described, with some variation of the accompanied neurologic deficits. Acute autonomic and sensory neuropathy(AASN) is characterized by the acute onset of autonomic dysfunction and sensory disturbances. A 16-year-old girl experienced high fever($40^{\circ}C$) and erythematous rash on whole trunk and face followed by pain and sensory loss over the whole body, dysphagia, ataxia, urinary retention, and postural hypotension. There was no evidence of limb weakness. The electrophysiologic studies of this patient revealed sensory polyneuropathy and the various autonomic function test showed autonomic dysfunction. The recovery of her autonomic and sensory symptoms is incomplete, three months after the onset of the symptoms. The etiology of the acute autonomic and sensory neuropathy is not known. Most previous authors have suggested the dysautonomia may be an acute immunological damage to peripheral fibers of the autonomic nervous system. We report a case of acute autonomic and sensory neuropathy.

This study was carried out to determine the relationship between smoke components and sensory evaluation by changes tobacco leaf blending. Seven different cigarettes were made by adding different types of oriental, reconstituted and expanded tobacco leaves. 62 kinds of smoke components which were 6 of general components, 34 of semi-volatile and volatile components, 9 of acid components, and 13 of phenolic components were analyzed. Eight kinds of sensory item were evaluated and also electronic nose system data was collected. All smoke components and sensory characteristics of mainstream smoke were changed by the different blending. To determine the relationship between smoke components and sensory test, the correlation and regression analysis were carried out by using SPSS statistical program. Tar, pH, and CO showed a high correlation with sensory evaluation item. As tar related to hotness, CO have a high correlation with offensive aroma. Semi-volatile and volatile components of smoke related to sensory characteristics such as aroma, taste, irritation, hotness and smoothness. When propylene, l,3-butadiene, butane, isoprene, and 2-methylfuran showed a high correlation with aroma; methyl chloride, methanol, toluene, ethyl benzene showed a high correlation with irritation. Some acidic components and phenolic components of smoke also had a high relation to smoke volume. Especially the acidic components such as 2-furoic acid, 2-hydroxybutyric acid, phenylacetic acid and palmitic acid; the phenolic components such as 4-vinyl phenol, pyrocatechol, 3-methyl catechol, hydroquinone showed a high correlation with smoke volume. As using regression analysis, it was possible to estimate the results of sensory evaluation from the smoke analysis data. From the results of electronic nose system analysis, we can find the different pattern by adding expanded tobacco leaf.

The objectives of this study were to perform a descriptive analysis to characterize and compare the sensory properties of commercial Makgeolli products as well as a cross-cultural comparison of the sensory descriptions of these products between two sensory panels (Korean and Japanese). The samples used in this study were seven different types of Makgeolli, which were commercial products. A total of 10 Korean and 7 Japanese panelists were selected in Korea. Each group was trained, and they identified product attributes and performed descriptive analyses independently. The Korean and Japanese panelists generated 34 and 28 sensory attributes, respectively, to describe appearance, odor/aroma, taste/flavor, texture, and after flavor of the products. There were significant differences among the samples for 24 attributes by Korean and 23 attributes by Japanese panelists. Although there was not a large difference in the number of descriptors between Korean and Japanese panels, the Korean panelists generated more various attributes associated with flavor than the Japanese panelists, and the attributes of Japanese panelists included references to non-food products such as rotten grass. Multiple factor analysis (MFA) was applied to the descriptive analysis data from the Korean and Japanese panels to delineate the associations between Makgeolli samples and their sensory characteristics. Both the Korean and Japanese panels clustered the JRM, JSM, KRM and KSM samples into one group and the CRM and BSM samples into another group. The ESM sample was distinguished from the other six samples. These results of the cross-cultural comparison suggest that comparative analyses of sensory profiles between cultures should be conducted regularly in future studies, and further research such as consumer acceptance tests should be conducted to determine the sensory characteristics that drive consumer acceptance of Makgeolli products in the context of increasing food product exports to other countries.

Background: To compare the sensory change and recovery of infraorbital area associated with zygomaticomaxillary and orbital floor fractures and their recoveries and investigate the factors that affect them. Methods: We retrospectively reviewed 652 patients diagnosed with zygomaticomaxillary (n= 430) or orbital floor (n= 222) fractures in a single center between January 2016 and January 2021. Patient data, including age, sex, medical history, injury mechanism, Knight and North classification (in zygomaticomaxillary fracture cases), injury indication for surgery (in orbital floor cases), combined injury, sensory change, and recovery period, were reviewed. The chi-square test was used for statistical analysis. Results: Orbital floor fractures occurred more frequently in younger patients than zygomaticomaxillary fractures (p< 0.001). High-energy injuries were more likely to be associated with zygomaticomaxillary fractures (p< 0.001), whereas low-energy injuries were more likely to be associated with orbital floor fractures (p< 0.001). The sensory changes associated with orbital floor and zygomaticomaxillary fractures were not significantly different (p= 0.773). Sensory recovery was more rapid and better after orbital floor than after zygomaticomaxillary fractures; however, the difference was not significantly different. Additionally, the low-energy group showed a higher incidence of sensory changes than the high-energy group, but the difference was not statistically significant (p= 0.512). Permanent sensory changes were more frequent in the high-energy group, the difference was statistically significant (p= 0.043). Conclusion: The study found no significant difference in the incidence of sensory changes associated with orbital floor and zygomaticomaxillary fractures. In case of orbital floor fractures and high-energy injuries, the risk of permanent sensory impairment should be considered.

Objective : This study aimed to investigate the effect of simultaneous application of peripheral nerve sensory stimulation and task-oriented training on the improvement of upper extremity motor function after stroke. Methods : This study included 29 patients with hemiplegia. The 14 subjects were in the peripheral nerve sensory stimulation and task-oriented training group for 4 weeks (30 min/d, 5 d/wk), while the 15 control group subjects underwent only task-oriented training for the same duration. The outcome measures were the percentage of voluntary baseline muscle contractions of the wrist and shoulder and Box and Block Test, grip and pinch strength, and Action Research Arm Test. Results : After 4 weeks, muscle activity of extensor carpi radialis, flexor carpi radialis and grip strength and Action Research Arm Test were significantly higher in the experimental group. Conclusion : Simultaneous application of the peripheral nerve sensory stimulation and task-oriented training was found to be superior to task-oriented training for improving upper extremity motor function of adults with stroke.

To evaluate the sensory characteristics of domestic or imported chilled and frozen pork butts, six samples were purchased and investigated. Sixty panels of sensory evaluation were consisted of six groups by sex and age. In the appearance test, many panels preferred the domestic frozen butt A obtained good scores in fat color and fat attachment (p<0.001). In the age group, the 20's consumer preferred the domestic chilled pork butt of A company, whereas the 30's and 40's consumers preferred the imported frozen butt of A company. According to the results from the triangle test, the combinations of domestic frozen butt B and imported frozen butt A was the most significantly distinguished among the pairs of raw and cooked butts.
