Objective : The objective of this study was to determine a discriminat validity of the Sensory Processing Scale-Children (SPS-C) for children with and without Sensory Processing Disorder (SPD). Method : The SPS-C was completed by parents of 151 Korean children including 68 typically developing children (control group), 83 children with SPD (known group) in the age range 3–5 years, in South Korea. ANCOVA with sex as covariable was used to identified the difference between the children with typically development and SPD. Results : Sensory processing differences in sensory domains and sensory factors were detected and the gender differences were not effective between typically developing children and children with SPD. Significant differences were found in all sensory domain score and total score except proprioceptive processing in sensory domain. In sensory factors, significant differences were found in overrsensitivity, underresponsivity, and discrimination, but sensory seeking was not significant. SPS-C was a valid assessment tool to identify or screen of SPD in Korea. Conclusion : The psychometric characteristics for the standardization study of SPS-C were presented, and the discriminant validity to screen the children with sensory processing problems was presented as a verified evaluation tool. SPS-C will be helpful in screening, analyzing and interpreting characteristics of sensory processing, and establishing an intervention plan.

Objective : Purpose of this study is to develop a Sensory Processing Scale for Children (SPS-C) to screen sensory processing problems for children aged 3 to 5, and examine validity of the assessment. Method : A draft version of Sensory Processing Scale for Children (SPS-C) has been developed and it was utilized to 138 caregivers of children who are 3 to 5 years old. Rasch analysis was used to test construct validity of SPS-C. Through the Rasch analysis, unidimensionality and adequacy of the rating scale were examined. Results : Based on the Rasch analysis, it was found that six items out of 56 items (10.7%) are misfits. And the results also showed that 3-points rating scale is more adequate than 5-points scale for SPC-C. Conclusion : The construct validity of a newly developed assessment, Sensory Processing Scale for Children (SPS-C), was established through this study. Further studies are needed to examine other psychometric properties of the assessment, using the one modified based on the results in this study.

The present study aimed to demonstrate the neural mechanisms that relate to the abnormal processing of facial expressions in individuals with post-traumatic stress symptom (PTSS). In particular, we investigated each processing stage's influence on facial expression recognition in individuals with PTSS. To investigate these mechanisms, we measured behavioral performances and event-related potentials (ERPs) as individuals performed a multi-morphed facial expression identification task. Participants were divided into two groups: those with PTSS and a control group without PTSS. Participants viewed representations of fearful, neutral, and happy facial expressions. ERP results revealed that, relative to the control group, the PTSS experience group experienced enhanced P1 amplitudes (reflecting rapid detection) and attenuated LPP amplitudes (reflecting later strategic processing) for all facial expressions. The behavioral data show that PTSS experience group committed more errors and were slower at detectingfacial expressions than were the controls. The difficulties individuals with PTSS face in recognizing facial expressions are explained by abnormal processing related to sustained attention or elaborating processing deficit.

Purpose: The open access (OA) movement has significantly improved access to academic content. However, the financial burden of article processing charges (APCs) and the lack of pricing transparency remain major concerns. This study aims to estimate APC costs by publisher and country, focusing on Korea, to inform policy decisions. Methods: We combined datasets from ScholCommLab (2019?2023), KESLI (2018?2024), and Web of Science (WoS). These sources were merged by aligning APC data with WoS-indexed articles, adjusting for missing values and currency differences. The final dataset included over 4.4 million records, enabling detailed analysis of APC expenditures by publisher and country. Results: From 2019 to 2023, global APC spending increased, with clear regional disparities. Italy showed the highest compound annual growth rate in APC costs at 34.17%, followed by moderate to high growth in Korea, Germany, and the United Kingdom. Korea and Italy allocated large proportions of APC spending to MDPI?38.71% and 37.53%, respectively?raising concerns about publisher dominance and potential quality issues. In contrast, Germany and the United Kingdom established national agreements aimed at controlling APC costs. Conclusion: This study underscores the growing global burden of APCs and the need for costmanagement strategies. Policymakers should consider targeted financial support and promote equitable publishing models. Adoption of the diamond OA model?which removes APCs for authors and provides free access to readers?offers a sustainable and inclusive path forward for academic publishing, addressing both financial and ethical challenges in the current OA landscape.

Lowenfeld developed sandplay therapy as a technique that allows children's multidimensional thoughts and emotions to be expressed more freely, while at the same time combining not only visual but also tactile and sensory factors. Since then, sandplay therapy has been used as a psychotherapy technique in various clinical settings around the world, but there has been no evidence-based research on sandplay therapy and sensory processing ability. This study investigated the clinical effects of school sandplay group counseling on sensory processing abilities in 20 sixth-grade elementary school students with suicide ideation. School sandplay group counseling was conducted for 8 sessions in 12 weeks, from March 2023, to June 2023. The subjects were sixth-grade students with suicide ideation from an elementary school in Chungcheongbuk-do, South Korea, with a single group of 10 males (50%) and 10 females (50%) without a control group. The average age of the participants was 11.74, with a range of 11.25-12.15. The Korean version of the SIQ-JR and the Korean version of the AASP were used as pretest and posttest instruments. The data were analyzed using SPSS 29.0. the paired-sample t-tests indicated statistically significant changes in low registration (p = .025), and suicide ideation (p = 0.017). The results of this study suggest that school sandplay group counseling may have clinical effects on sensory processing abilities and suicide ideation in elementary school children with suicide ideation.

Objective To investigate the hemispheric contributions to prosody recognitions and interference effects of semantic processing on prosody for stroke patients by using the Korean language.Methods Ten right hemisphere damaged patients (RHD), nine left hemisphere damaged patients (LHD), and eleven healthy controls (HC) participated. In pure prosody recognition task, four semantically neutral sentences were selected and presented in both sad and happy prosodies. In interference task, participants listened to emotionally intoned sentences in which the semantic contents were congruent or incongruent with prosody. Participants were asked to rate the valence of prosody while ignoring the semantic contents, and thus, reaction time and accuracy were estimated.Results In pure prosody recognition task, RHD showed low accuracy as compared to HC (p=0.013), and the tendency of group response showed that RHD performed worse than HC and LHD with regards to accuracy and reaction time. In interference task, analysis of accuracy revealed a significant main effect of groups (p=0.04), and the tendency implied that RHD is less accurate as compared to LHD and HC. The RHD took longer reaction times than HC in congruent and incongruent items (p<0.001).Conclusion Right hemispheric laterality to prosody processing of Korean language in stroke patients was observed. Interference effects of semantic contents to prosody processing were not observed, which suggested unique characteristics of prosody for Korean language. These results could be referred as preliminary data for future researches on Korean languages.

Purpose: This study aims to compare the internal and marginal accuracy of provisional crowns fabricated using the digital light processing (DLP) three-dimensional (3D) printing method, considering build directions of 0° and 90°, as well as layer thicknesses of 50 μm, 75 μm, and 100 μm. Methods: Provisional crowns were fabricated using a DLP 3D printer, and six experimental groups were created, each comprising 10 specimens. Provisional crowns were designed with computer-aided design software and printed using a liquid resin material. Internal and marginal accuracy were assessed using root mean square (RMS) values. Statistical analyses, including two-way ANOVA and Tukey HSD tests (α=0.05), were conducted to evaluate the effects of build direction and layer thickness on RMS values. Results: For the trueness of the internal surface, the lowest RMS value (31.56±4.47 μm) was observed at a 0° build direction with a layer thickness of 100 μm. At 90° with 100 μm, the RMS value was 64.72±4.96 μm (p<0.05). Marginal trueness at a 0° build direction with 75 μm showed the lowest value of 31.88±6.89 μm, while at 90° with 75 μm it was 85.40±22.45 μm (p<0.001). Differences between build direction and layer thickness combinations were confirmed for both internal and marginal trueness (p<0.001). Conclusion: The effects of build directions (0°, 90°) and layer thicknesses (50 μm, 75 μm, 100 μm) on the internal and marginal accuracy of printed crowns were analyzed, revealing a significant interaction in both internal and marginal trueness.

Purpose: This study aimed to evaluate the trueness of three-dimensional (3D) printed zirconia single crowns using digital light processing with different build angles. Methods: A prepped maxillary right first molar model was scanned using a dental laboratory scanner (E4, 3Shape A/S). The anatomically contoured crown was designed using computer- aided design software (Dental Designer, 3Shape A/S) and saved as a standard tessellation language file. Three build angles (0°, 30°, and 60°) were defined using the slicing software (Zipros, AON). The crowns were printed using a digital light-processing 3D printer (N=30), followed by debonding and sintering to achieve the final shape. The crowns were scanned postprocessing and analyzed for trueness using 3D inspection software. Data were statistically analyzed with the one-way analysis of variance and Bonferroni post hoc tests. Results: The root mean square (RMS) values for the internal segments were 40.23 (0°), 53.01 (30°), and 82.49 (60°) μm. The marginal segments recorded RMS values of 34.63 (0°), 59.97 (30°), and 84.16 (60°) μm. Statistical analysis revealed significant differences among the groups (p<0.001). Conclusion: The results indicate that a 0° build angle with uniform height support structures provides the highest accuracy in digital light processing of 3D printed zirconia crowns.

Data analysis was carried out using Excel Content validity indices (CVI), mean, and standard deviation were used for the analysis of content validity. Results : The result of the comparison between the original SPM and K-SPM in the group of experts was 3.54 ± .74, the S-CVI/Avg for semanticity was .92, and the S-CVI/Avg for structure was .86. The results for the mean of the understanding test and the S-CVI/Avg were 3.48 ± .63 and .94, respectively. Conclusion : K-SPM will considerately be used as an assessment to identify sensory processing, praxis, and social participation issues for children in Korea. Further studies are suggested to increase the age range and the sample size for a more comprehensive applicability of the K-SPM to Korean children.

A review of the studies on infant learning, stimulus preferences. and habituation supports the following assertions. Firstly, the finding that a very young infant is capable of control of his basic responses if required implies that his ability for differentiating critical stimulus features is sufficiently adequate to be utilized in response adaptation. Secondly, results from both stimulus preference, and habituation studies indicate that before the infant is able to manage his motoric response, he is extensively engaged in stimulus differentiation and information processing. Thirdly, evidence from current habituation research using more elaborate procedures suggests that attentional processing under habituation is more than a single phenomenon, possibly involving multi-level processing. And lastly, existing data support Jeffrey's hypothesis of serial habituation as a mechanism for perceptual development.
