Improved high voltage operation of amorphous In-Ga-Zn-O thin film transistor by carrier density enhancement.

We report on improved high voltage operation of amorphous-In-Ga-Zn-O (a-IGZO) thin film transistors (TFTs) by increasing carrier density and distributing the high bias field over the length of the device which utilizes an off-set drain structure. By decreasing the O2partial pressure during sputter deposition of IGZO, the channel carrier density of the high voltage a-IGZO TFT (HiVIT) was increased to ∼1018cm-3. Which reduced channel resistance and therefore the voltage drop in the ungated offset region during the on-state. To further decrease the electric field in the offset region, we applied Ta capping and subsequent oxidation to locally increase the oxygen vacancy levels in the offset region thereby increasing local carrier density. The reduction of the drain field in the offset region from 1.90 Vµm-1to 1.46 Vµm-1at 200 V drain voltage, significantly improved the operational stability of the device by reducing high field degradation. At an extreme drain voltage of 500 V, the device showed an off-state current of ∼10-11A and on-state current of ∼1.59 mA demonstrating that with further enhancements the HiVIT may be applicable to thin-film form, low leakage, high voltage control applications.

A Study on the Screening of Children at Risk for Developmental Disabilities Using Facial Landmarks Derived From a Mobile-Based Application.

OBJECTIVE: Early detection and intervention of developmental disabilities (DDs) are critical to improving the long-term outcomes of afflicted children. In this study, our objective was to utilize facial landmark features from mobile application to distinguish between children with DDs and typically developing (TD) children. METHODS: The present study recruited 89 children, including 33 diagnosed with DD, and 56 TD children. The aim was to examine the effectiveness of a deep learning classification model using facial video collected from children through mobile-based application. The study participants underwent comprehensive developmental assessments, which included the child completion of the Korean Psychoeducational Profile-Revised and caregiver completing the Korean versions of Vineland Adaptive Behavior Scale, Korean version of the Childhood Autism Rating Scale, Social Responsiveness Scale, and Child Behavior Checklist. We extracted facial landmarks from recorded videos using mobile application and performed DDs classification using long short-term memory with stratified 5-fold cross-validation. RESULTS: The classification model shows an average accuracy of 0.88 (range: 0.78-1.00), an average precision of 0.91 (range: 0.75-1.00), and an average F1-score of 0.80 (range: 0.60-1.00). Upon interpreting prediction results using SHapley Additive exPlanations (SHAP), we verified that the most crucial variable was the nodding head angle variable, with a median SHAP score of 2.6. All the top 10 contributing variables exhibited significant differences in distribution between children with DD and TD (p<0.05). CONCLUSION: The results of this study provide evidence that facial landmarks, utilizing readily available mobile-based video data, can be used to detect DD at an early stage.

Gut microbial and clinical characteristics of individuals with autism spectrum disorder differ depending on the ecological structure of the gut microbiome.

Understanding the relationship between the gut microbiome and autism spectrum disorder (ASD) is challenging due to the heterogeneous nature of ASD. Here, we analyzed the microbial and clinical characteristics of individuals with ASD using enterotypes. A total of 456 individuals participated in the study, including 249 participants with ASD, 106 typically developing siblings, and 101 controls. The alpha and beta diversities of the ASD, sibling, and control groups did not show significant differences. Analysis revealed a negative association between the Bifidobacterium longum group and the Childhood Autism Rating Scale, as well as a negative association between the Streptococcus salivarus group and the Social Responsiveness Scale (SRS) within the ASD group. When clustered based on microbial composition, participants with ASD exhibited two distinct enterotypes, E1 and E2. In the E2 group, the SRS score was significantly higher, and the Vineland Adaptive Behavior Scale score was significantly lower compared to the E1 group. Machine learning results indicated that the microbial species predicting SRS scores were distinct between the two enterotypes. Our study suggests that the microbial composition in individuals with ASD exhibits considerable variability, and the patterns of associations between the gut microbiome and clinical symptoms may vary depending on the enterotype.

Perceived trauma nursing core competency, interprofessional collaborative competency, and associated barriers among regional trauma center nurses.

INTRODUCTION: As key members of interprofessional teams working in complex settings, nurses in trauma centers require trauma nursing core competency. PURPOSE: This study sought to determine the levels and relationships of the perceived importance and performance of trauma nursing core competency, as well as the interprofessional collaborative competency and associated barriers among Korean regional trauma center nurses. METHODS: This cross-sectional, descriptive, and correlational survey involved a convenience sample of 190 Korean trauma center nurses. Data were collected using a web-based self-reporting questionnaire about the perceived importance and performance of trauma nursing core competency, as well as the interprofessional collaborative competency and associated barriers. Data were analyzed using descriptive statistics, Pearson's correlation, and multiple regression (Enter method) analyses. RESULTS: The perceived performance and importance of interprofessional collaborative competency, the perceived importance of trauma nursing core competency, and the perceived barriers to resources, training, competency, and interest significantly affected trauma nursing core competency performance, accounting for 64.5 % of the variance. CONCLUSIONS: Training programs are needed to improve the core and interprofessional collaborative competencies of trauma nurses. Individual, team, and organizational approaches are essential to addressing the perceived barriers. The effects of training programs on the core competency of trauma nurses should be validated.

Factors in Parenting Stress in Young Patients With Breast Cancer and Implications for Children's Emotional Development: The PSYCHE Study.

Importance: The number of patients with breast cancer who have children is substantial. However, the emotional burden of this disease and its implication for childhood development remain largely unknown. Objective: To investigate the clinical factors in parenting stress in mothers with breast cancer and the association of maternal depression and parenting stress with their children's emotional development. Design, Setting, and Participants: This cross-sectional study involved a survey of females with stage 0 to 3 breast cancer and was conducted from June 2020 to April 2021 in Seoul, South Korea. Participants were aged 20 to 45 years and completed the Center for Epidemiologic Studies Depression-Revised scale and basic questionnaires on demographic and clinical characteristics. Participants with children completed the Korean Parenting Stress Index Short Form (K-PSI-SF), Child Behavior Checklist, Junior Temperament and Character Inventory, and Children's Sleep Habits Questionnaire. Exposure: Having children in patients with breast cancer. Main Outcomes and Measures: Multivariable logistic and linear regression analyses were performed to investigate the association between maternal depression and parenting stress. Results: A total of 699 females (mean [SD] age, 39.6 [4.6] years) were included, of whom 499 had children (mean [SD] age of children, 8.0 [2.7] years). Depression was more common in patients with children (odds ratio [OR], 2.25; 95% CI, 1.01-5.05) and patients who had gonadotropin-releasing hormone treatment (OR, 1.68; 95% CI, 1.15-2.44). Disease duration was inversely associated with depression (OR, 0.85; 95% CI, 0.76-0.96). Cancer-related factors were not associated with the K-PSI-SF score. Having children aged 6 years or older (ß = 3.09; 95% CI, 0.19-5.99); being the sole primary caregiver (ß = -3.43; 95% CI, -5.87 to -0.99); and reporting certain temperament (eg, novelty seeking: ß = 0.58; 95% CI, 0.46-0.71), emotional problems (eg, anxious/depressed: ß = 8.09; 95% CI, 3.34-12.83), and sleeping pattern (eg, bedtime resistance: ß = 0.57; 95% CI, 0.15-0.99) subscale scores in their children were associated with parenting stress. Depression and parenting stress were correlated (ß = 0.56; 95% CI, 0.45-0.66; P < .001). The emotional challenges encountered by children of mothers with breast cancer were not significantly different from reference values. Conclusions and Relevance: This study found that in patients with breast cancer, child-related factors and depression were significantly associated with parenting stress, but breast cancer-related factors were not correlated. The findings suggest that mothers with breast cancer are susceptible to both depression and parenting stress and that tailored counseling and support are needed.

Psychoeducational Profile-Revised, Korean Wechsler Preschool and Primary Scale of Intelligence, Fourth Edition, and the Vineland Adaptive Behavior Scale, Second Edition: Comparison of Utility for Developmental Disabilities in Preschool Children.

Objectives: This study aimed to compare the utility of the Psychoeducational Profile-Revised (PEP-R), Korean Wechsler Preschool and Primary Scale of Intelligence, Fourth Edition (K-WPPSI-IV), and Vineland Adaptive Behavior Scale, Second Edition (VABS-II) for evaluating developmental disabilities (DD) in preschool children. Additionally, we examined the correlations between the PEP-R, KWPPSI- IV, and VABS-II. Methods: A total of 164 children aged 37-84 months were assessed. Children's development was evaluated using the PEP-R, K-WPPSIIV, VABS-II, Preschool Receptive-Expressive Language Scale, and Korean Childhood Autism Rating Scale, Second Edition. Results: Of the 164 children, 103 had typical development (TD) and 61 had DD. The mean of the PEP-R Developmental Quotient (DQ), K-WPPSI-IV Full-Scale Intelligence Quotient (FSIQ), and VABS-II Adaptive Behavior Composite (ABC) scores were significantly higher in the TD group than in the DD group (p<0.001). The estimated area under the curve of the PEP-R DQ, K-WPPSI-IV FSIQ, and VABS-II ABC scores was 0.953 (95% confidence interval [CI]=0.915-0.992), 0.955 (95% CI=0.914-0.996), and 0.961 (95% CI=0.932- 0.991), respectively, which did not indicate a statistically significant difference. The PEP-R DQ scores were positively correlated with the K-WPPSI-IV FSIQ (r=0.90, p<0.001) and VABS-II ABC scores (r=0.84, p<0.001). A strong correlation was observed between the KWPPSI- IV FSIQ and VABS-II ABC scores (r=0.89, p<0.001). Conclusion: This study found that the PEP-R, K-WPPSI-IV, and VABS-II effectively distinguished DD from TD in preschool children, and no significant differences in utility were observed between them.

Impact of Comorbid Oppositional Defiant Disorder on the Clinical and Neuropsychological Characteristics of Korean Children With Attention-Deficit/Hyperactivity Disorder.

OBJECTIVE: The aim of the present study was to investigate the influence of comorbid oppositional defiant disorder (ODD) on clinical features and neuropsychological profiles of children with attention-deficit/hyperactivity disorder (ADHD). METHODS: We divided the participants into three groups: the ADHD with ODD (ADHD/ODD) (n=36), ADHD without ODD (ADHD/noODD) (n=307), and control groups (n=128). Parents of the participants completed the ADHD Rating Scale, Social Responsiveness Scale (SRS), Korean Personality Rating Scale for Children (K-PRC), and 10-item mania scale from the Parent General Behavior Inventory (P-GBI-10M). Neuropsychological profiles were assessed using the Advanced Test of Attention (ATA), Children's Color Trails Test, and Stroop Color and Word Test. RESULTS: The ADHD/ODD group had more ADHD symptoms and functional impairments in relationships with teachers and peers, and self-esteem than the ADHD/noODD group. The ADHD/ODD group scored higher in Social Communication (p<0.001) and Autistic Mannerisms (p<0.001) subscales of SRS, P-GBI-10M (p<0.001), and Delinquency (p<0.001) and Psychosis (p<0.001) subscales of K-PRC than the ADHD/noODD group. Commission Errors (p<0.001) and Response-Time Variability (p<0.001) in Visual ATA and Commission Errors (p<0.001) in Auditory ATA were significantly higher in the ADHD/ODD group than in the ADHD/noODD group. CONCLUSION: The present study suggests that patients with ADHD with ODD experience more ADHD symptoms and neuropsychological deficits than those with ADHD without ODD. These results also imply that comorbid ODD is associated with greater social impairment and emotional dysregulation.

Deviated Saccadic Trajectory as a Biometric Signature of Glaucoma.

Purpose: To investigate whether the trajectories of saccadic eye movements (SEMs) significantly differ between glaucoma patients and controls. Methods: SEMs were recorded by video-based infrared oculography in 53 patients with glaucoma and 41 age-matched controls. Participants were asked to bilaterally view 24°-horizontal, 14°-vertical, and 20°-diagonal eccentric Goldmann III-sized stimuli. SEMs were evaluated with respect to the saccadic reaction time (SRT), the mean velocity, amplitude, and two novel measures: departure angle (DA) and arrival angle (AA). These parameters were compared between the groups and the associations of SEM parameters with glaucoma parameters and integrated visual field defects were investigated. Results: Glaucoma patients exhibited increased mean SRT, DA, and AA values compared with controls for 14°-vertical visual targets (P = 0.05, P < 0.01, and P < 0.01, respectively). The SRT, DA, and AA were significantly associated with the mean and pattern standard deviations of perimetry and with the mean RNFL thickness by OCT (all P < 0.001). Glaucoma was associated with the AA (P = 0.05) and both the SRT (P = 0.01) and DA (P = 0.04) were associated with integrated visual field defects. Conclusions: The saccadic trajectories of glaucoma patients depart in an erroneous path and compensate the disparity by deviating the trajectory at arrival. Translational Relevance: The initial deviation that we observed (despite continuous exposure to the stimulus) suggests the disoriented spatial perception of glaucoma patients which may be relevant to difficulties encountered daily.

Recent progress in the role of grain boundaries in two-dimensional transition metal dichalcogenides studied using scanning tunneling microscopy/spectroscopy.

Grain boundaries (GBs) are one- or two-dimensional (2D) defects, which are universal in crystals and play a crucial role in determining their mechanical, electrical, optical, and thermoelectric properties. In general, GBs tend to decrease electrical or thermal conductivity, and consequently degrade the performance of devices. However, the unusual characteristics of GBs have led to the production of a new class of memristors with 2D semiconducting transition metal dichalcogenides (TMDs) and the creation of conducting channels in 2D topological insulators. Therefore, understanding the nature of GBs and their influence on device applications emphasizes the importance of GB engineering for future 2D TMD-based devices. This review discusses recent progress made in the investigation of various roles of GBs in 2D TMDs characterized via scanning tunneling microscopy/spectroscopy.

The Association Between Media-Based Exposure to Nonsuicidal Self-Injury and Emergency Department Visits for Self-Harm.

OBJECTIVE: This study aimed to evaluate the association between media-based exposure to nonsuicidal self-injury (NSSI) and emergency department (ED) visits due to self-harm in Korea, specifically before and after the initial broadcast of the song Barcode, which has an explicit focus on NSSI. METHOD: We used the national emergency department information system to obtain data related to ED visits due to self-harm between January 1, 2014, and December 31, 2018. Using interrupted time series regression analysis, we assessed the monthly ED visits due to self-harm before and after the media-based exposure to NSSI on March 30, 2018. In addition, self-harm methods were assessed. RESULTS: A total of 35,928,834 visits to ED were identified, of which 115,647 were due to self-harm. ED visits due to self-harm showed a significant step increase in the 10- to 14-year-old (ß = 0.883, p = .001), 15- to 19-year-old (ß = 2.941, p < .001), 20- to 24-year-old (ß = 1.997, p = 0.002), and 25- to 29-year-old (ß = 1.438, p = .029) age groups, before and after the media-based exposure to NSSI. The most pronounced increase was observed in male participants aged 20 to 24 years (ß = 1.790, p = .012) and female participants aged 15 to 19 years (ß = 5.158, p < .001). Self-harm by cutting has increased significantly in participants aged 10 to 29 years, and self-harm by poisoning has also increased significantly in participants aged 10 to 19 and 25 to 29 years. CONCLUSION: ED visits due to self-harm increased significantly, especially in adolescents and young adults, following the exposure to NSSI. Responsible media reporting on NSSI and appropriate guidelines would help prevent a further increase in self-harm.

Chronic exposure to environmental concentrations of harmful algal bloom-forming dinoflagellates induces oxidative stress and reduces immune and hepatic functions in red seabream.

Harmful algal blooms (HABs) caused by dinoflagellates can be detrimental to aquaculture and fisheries. However, little is known regarding their ichthyotoxic effects on fish, particularly after chronic exposure to sublethal levels. In this study, significant modulations in physiology, immunity, antioxidant components, and hepatic indicators owing to non-toxin-producing dinoflagellate strains (Alexandrium affine and Cochlodinium polykrikoides) were analyzed in juvenile red seabream, Pagrus major, exposed to sublethal concentrations (0, 1, and 100 cells mL-1) for 60 days. At 60 days, higher mortality was induced by A. affine than by C. polykrikoides. Significant increases in respiration rate and plasma cortisol were observed in red seabream exposed to 100 cells mL-1 of the two dinoflagellates. Intracellular reactive oxygen species and malondialdehyde levels were significantly elevated in the gill and liver tissues in response to 100 cells mL-1 of either dinoflagellate. Immunity parameters such as alternative complement activity, lysozyme activity, and total immunoglobulin content were significantly decreased during exposure to 100 cells mL-1 of the two dinoflagellates. Although no significant change was observed in the gonadosomatic index, the hepatosomatic index was significantly decreased by exposure to 100 cells mL-1 of the two dinoflagellates on day 60. The significant decrease in enzymatic activities of ethoxyresorufin-O-deethylase, alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase upon exposure to 100 cells mL-1 of either dinoflagellate suggested impaired hepatic function through prolonged exposure. Our results suggest that consistent exposure to sublethal concentrations of HAB-forming dinoflagellates is detrimental to fish physiology and biochemical defenses.

Children's and Parents' Factors That Affect Parenting Stress in Preschool Children With Developmental Disabilities or Typical Development.

OBJECTIVE: This study compared parenting stress in preschool children with developmental disabilities (DD) or typical development (TD). We also investigated children's factors that affect parenting stress. METHODS: A total of 196 preschool children participated in the study (aged 54.8±9.2 months). There were 79 children with DD (59 with autism spectrum disorder, 61 with intellectual disability, 12 with language disorder) and 117 with TD. The high parenting stress and the low parenting stress groups were divided based on the Total Stress of Korean Parenting Stress Index Fourth Edition (K-PSI-4) with an 85-percentile cutoff score. Pearson's correlation analysis was conducted to calculate the correlation between K-PSI-4 and the children's or parents' measures. RESULTS: The difference in parenting stress between DD and TD was significant in the Total Stress of K-PSI-4 (p<0.001). The Total Stress scale of K-PSI-4 represented a modest to strong correlation with cognitive development, adaptive functioning, social communication, and behavioral problems in children with DD. Our results showed that caregivers of children with DD reported higher parenting stress than those with TD. Parenting stress was strongly associated with cognitive development, adaptive functioning, social communication, and behavioral problems in children with DD. Among the children's factors, especially social communication, attention problems, and aggressive behavior had association with caregivers' higher parenting stress. CONCLUSION: These findings suggest the need for early intervention for parenting stress in caregivers by assessing child characteristics, including social cognition, awareness, communication, and inattention and hyperactivity, in the evaluation of children with DD.

Long-Term Improvement and Safety of Aripiprazole for Irritability and Adaptive Function in Asian Children and Adolescents with Autistic Disorder: A 52-Week, Multinational, Multicenter, Open-Label Study.

Objective: Evaluate the long-term improvement and safety of aripiprazole in treating irritability in Asian children and adolescents (6-17 years) with autistic disorder. Methods: A 52-week, open-label, flexibly dosed (2-15 mg/day) study on the improvement and safety of aripiprazole in patients with autistic disorder who had completed an antecedent 12-week open-label study. The evaluation of efficacy was conducted using the Aberrant Behavior Checklist (ABC), Clinical Global Impression (CGI) scale, Child Yale-Brown Obsessive-Compulsive Scale (CY-BOCS), Vineland Adaptive Behavior Scale (VABS), and the Parenting Stress Index-Short Form (PSI-SF). Safety and tolerability measurements included adverse events, vital signs, electrocardiography, laboratory tests, body weight, and extrapyramidal symptoms (EPSs). Results: During the 52-week treatment, all effectiveness variables, including ABC, CGI, CY-BOCS, VABS, and PSI-SF scores, showed improvement. Regarding safety, the proportion of patients who experienced any treatment-emergent adverse events (TEAEs) was 58.62% (34/58 subjects, 75 cases). The most common TEAE was nasopharyngitis reported in 20.69% (15/58 subjects, 15 cases) and the other TEAE with an incidence of ≥10% was weight increases in 18.97% (11/58 subjects, 11 cases). Of them, 27.59% (16/58 subjects, 28 cases) experienced adverse drug reactions (ADRs). The most common ADR was weight increase reported in 15.52% (9/58 subjects, nine cases). The incidence of serious adverse events (SAEs) was 5.17% (3/58 subjects, three cases), which were epiphysiolysis, seizure, and a suicide attempt, but these were not ADRs. There were no clinically significant changes found in the evaluation of EPSs. Conclusions: Aripiprazole showed improvement for behavioral problems and adaptive functioning and was well tolerated in patients with autistic disorder until nearly a year after drug use. The Clinical Trial Registration number: NCT02069977.

Biohydrogen production and purification: Focusing on bioelectrochemical systems.

Innovative technologies on green hydrogen production become significant as the hydrogen economy has grown globally. Biohydrogen is one of green hydrogen production methods, and microbial electrochemical cells (MECs) can be key to biohydrogen provision. However, MECs are immature for biohydrogen technology due to several limitations including extracellular electron transfer (EET) engineering. Fundamental understanding of EET also needs more works to accelerate MEC commercialization. Interestingly, studies on biohydrogen gas purification are limited although biohydrogen gas mixture requires complex purification for use. To facilitate an MEC-based biohydrogen technology as the green hydrogen supply this review discussed EET kinetics, engineering of EET and direct interspecies electron transfer associated with hydrogen yield and the application of advanced molecular biology for improving EET kinetics. Finally, this article reviewed biohydrogen purification technologies to better understand purification and use appropriate for biohydrogen, focusing on membrane separation.

Brief Report: Risk Variants Could Inform Early Neurodevelopmental Outcome in Children with Developmental Disabilities.

The aim of this study was to examine genetic variations underlying the early neurodevelopmental outcome of developmental disabilities (DDs). The study cohort consisted of 191 children with DDs. Diagnosis was assessed at baseline and at the index age (72-84 months). Exome sequencing was conducted and putative risk variants were identified. According to the diagnostic improvement, children were categorized into the improvement group (n = 19) and the non-improvement group (n = 172). Compared to the non-improvement group, the improvement group had lower number of risk variants in known DD genes and haploinsufficient genes, and lower number of overall putative risk variants. Our results may serve as a preliminary basis for developing a model that informs clinical outcome by sequencing analysis.

The complete mitochondrial genome and phylogenetic position of the Scalpel sawtail Prionurus scalprum Valenciennes, 1835 (Acanthuriformes: Acanthuridae) from Jeju Island, Korea.

Although the mitochondrial genomes of most Acanthuriformes fish have been sequenced, this has not been done for Prionurinae fish yet. The Scalpel sawtail (Prionurus scalprum Valenciennes, 1835) found in all tropical and sub-tropical seas, is an important link between primary producers and higher trophic levels. In this study, the complete mitochondrial genome of the Scalpel sawtail, Prionurus scalprum Valenciennes, 1835 (accession number: OK323243) was sequenced. The complete mitochondrial genome included 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes, and a control region; the total length was 16,522 bp. The nucleotide composition of the genome was as follows: A, 28.46%; T, 27.62%; G, 16.46%; and C, 27.46%. All genes were encoded on the H-strand, except for the eight tRNA genes and NADH dehydrogenase subunit (ND6). A phylogenetic tree was constructed using the neighbor-joining (NJ) method and the phylogenetic position of the Scalpel sawtail was established. This provides useful data for future research on Acanthuridae fish.

3D Reconstruction of a Unitary Posterior Eye by Converging Optically Corrected Optical Coherence and Magnetic Resonance Tomography Images via 3D CAD.

Purpose: In acquiring images of the posterior eye, magnetic resonance imaging (MRI) provides low spatial resolution of the overall shape of the eye while optical coherence tomography (OCT) offers high spatial resolution of the limited range. Through the merger of the two devices, we attempted to acquire detailed anatomy of the posterior eye. Methods: Optical and display distortions in OCT images were corrected using the Listing reduced eye model. The 3.0T orbital MRI images were placed on the three-dimensional coordinate system of the computer-aided design (CAD) program. Employing anterior scleral canal opening, visual axis, and scleral curvature as references, original and corrected OCT images were ported into the CAD application. The radii of curvature of the choroid-scleral interfaces (Rc values) of all original and corrected OCT images were compared to the MRI images. Results: Sixty-five eyes of 33 participants (45.58 ± 19.82 years) with a mean Rc of 12.94 ± 1.24 mm on axial MRI and 13.66 ± 2.81 mm on sagittal MRI were included. The uncorrected horizontal OCT (30.51 ± 9.34 mm) and the uncorrected vertical OCT (34.35 ± 18.09 mm) lengths differed significantly from the MRI Rc values (both P < 0.001). However, the mean Rc values of the corrected horizontal (12.50 ± 1.21 mm) and vertical (13.05 ± 1.98 mm) images did not differ significantly from the Rc values of the corresponding MRI planes (P = 0.065 and P = 0.198, respectively). Conclusions: Features identifiable only on OCT and features only on MRI were successfully integrated into a unitary posterior eye. Translational Relevance: Our CAD-based converging method may establish the collective anatomy of the posterior eye and the neural canal, beyond the range of the OCT.

Predictors of Developmental Outcome in 4- to 6-Year-Olds With Developmental Disability.

OBJECTIVE: Studies on the early trajectories of developmental disability (DD) are limited. This study aimed to evaluate the diagnostic stability and developmental trajectories of autism spectrum disorder (ASD) and intellectual disability (ID), and to determine baseline clinical characteristics that affect future diagnosis. METHODS: We analyzed 192 children who were referred for possible DD through retrospective chart review. Clinical diagnosis was assessed once at baseline, aged 2-4, and at follow-up, aged 4-6. The participants' developmental profiles were measured by Psychoeducational Profile-Revised (PEP-R), Vineland Social Maturity Scale (VSMS), Beery-Buktenica Developmental Test of Visual Motor Integration (VMI), and Childhood Autism Rating Scale (CARS). RESULTS: On comparing the diagnostic change, 5% of children were no longer diagnosed as ASD, and 13% of children were no longer diagnosed as ID at follow-up. Trajectories of developmental profiles were compared between children with and without ID at follow-up, and significant time-by-group interaction were observed in PEP-R (p<0.001), VSMS (p<0.001), and VMI (p=0.003) scores, indicating that children without ID at follow-up showed significant improvement over time compared to children with ID. ASD diagnosis (p<0.001) and CARS score (p=0.007) at baseline were significantly associated with ASD at follow-up, while VSMS score (p=0.004) and VMI score (p=0.019) at baseline were significantly associated with ID at follow-up. CONCLUSION: A subset of children lost their diagnosis at follow-up, and such diagnostic change was significantly more common in ID compared to ASD. Baseline autism symptomatology was related to ASD at follow-up, and baseline adaptive and visuo-motor function was related to ID at follow-up.

Mediating Effect of Viral Anxiety and Perceived Benefits of Physical Distancing on Adherence to Distancing Among High School Students Amid COVID-19.

BACKGROUND: The aim of this study is to explore whether high school students' adherence to physical distancing was associated with health beliefs, social norms, and psychological factors during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: Overall, 300 high school students participated in this anonymous online survey conducted from October 18-24, 2021. The survey included rating scales such as attitude toward physical distancing during the pandemic, Stress and Anxiety to Viral Epidemics-6 items (SAVE-6), Patient Health Questionnaire-9 items, Satisfaction with Life Scale, and Connor Davidson Resilience Scale 2-items. RESULTS: The results revealed that perceived susceptibility or severity (ß = -0.13, P = 0.038), perceived benefit (ß = 0.32, P < 0.001), descriptive social norms (ß = 0.10, P = 0.041), social injunctive norms (ß = 0.19, P < 0.001), and SAVE-6 (ß = 0.24, P < 0.001) predicted students' adherence to physical distancing (adjusted R² = 0.42, F = 19.2, P < 0.001). Social injunctive norms and personal injunctive norms directly influenced adherence to physical distancing. Viral anxiety, measured by SAVE-6, mediated the association between social injunctive norms and adherence to physical distancing, and perceived benefits mediated the relationship between personal injunctive norms and adherence to physical distancing. The influence of perceived susceptibility or severity on adherence to physical distancing was entirely mediated by perceived benefits or viral anxiety. CONCLUSION: Explaining the rationale or benefits of physical distancing may be important in increasing adherence to physical distancing among high school students.

Efficacy of Mobile-Based Cognitive Training Program DoBrain in Preschool Children With or Without Developmental Disabilities: A Randomized, Single-Blind, Active-Controlled Trial.

OBJECTIVE: Mobile-based cognitive training programs can be a viable alternative to in-person interventions, but their efficacies have not been established yet. In this study, we examined the efficacy of DoBrain, a mobile-based cognitive training program designed for children with developmental disabilities (DDs), in comparison with general educational apps named Junior Naver and Kakao Kids. METHODS: Children aged 34 to 77 months were recruited and randomized at a 1:1 ratio to use DoBrain or general educational apps. Each group used the assigned app on a daily basis at home for 30 minutes for 24 weeks. Parents were instructed to help the children with the app usage. A total of 166 children completed the post-test visit (DoBrain group, n=85, 55.4±8.7 months old; general educational app group, n=81, 53.7±9.9 months old). The primary outcome was cognitive development measured by Psychoeducational Profile-Revised (PEP-R), administered at baseline and at post-test. RESULTS: DoBrain had no superior effect over general educational apps on the PEP-R Developmental Quotient. When the changes before and after app usage were compared, the DoBrain group and the general educational app group both showed declines in imitation (adjusted p=0.049 and 0.022), perception (adjusted p=0.004 and <0.001), and gross motor (adjusted p=0.003 and 0.002) domains of the PEP-R. Among the DoBrain group, children with DD showed a significantly greater gain in the eye-hand coordination domain of PEP-R compared with those without DD (adjusted p=0.047). CONCLUSION: DoBrain did not show a superior effect over general educational apps on overall cognitive development in preschool children, regardless of the presence of DD. Careful monitoring of the negative effect of mobile-based cognitive training programs is necessary.
