Objective The aim of this study was to explore the psychometric properties Insomnia Severity Index (ISI) based on modern test theory, such as item response theory (IRT) and Rasch analysis, with shortened versions ISI among general population.Methods We conducted two studies evaluate reliability validity in a Korean population. In Study I, via online survey, we performed an exploratory factor analysis (n=400). II, confirmatory (CFA) IRT were all samples. Participants symptoms rated using ISI,...
This study aimed to investigate the potential correlation between baseline characteristics of individuals visiting an emergency room for a suicide attempt and subsequent psychiatric outpatient treatment adherence.Medical records 525 subjects, who visited at university-affiliated hospital January 2017 December 2018 were retrospectively reviewed. Potential associations visitation statistically analyzed.107 out (20.4%) attempted clinic after initial visit. Several factors (e.g., sober during...
Numerous devices have been studied to accomplish a brain-inspired neuromorphic computing system; however, their characteristics require improvement enhance operation accuracy of systems. Here, we propose ferroelectric field-effect transistor based on Hf0.5Zr0.5O2 for high-performance artificial synaptic device by reducing interface trap density. Using polarization in the layer, threshold voltage is precisely controlled achieve characteristics. However, are degraded because traps cause shift...

Dimensionality reduction (DR) techniques are essential for visually analyzing high-dimensional data. However, visual analytics using DR often face unreliability, stemming from factors such as inherent distortions in projections. This unreliability can lead to analytic insights that misrepresent the underlying data, potentially resulting misguided decisions. To tackle these reliability challenges, we review 133 papers address of DR. Through this review, contribute (1) a workflow model...
The blood-brain barrier (BBB) breakdown has been suggested as an early marker for Alzheimer's disease (AD); yet the relationship between BBB and AD-specific biomarkers based on amyloid/tau/neurodegeneration framework is not clear. This study investigated permeability, biomarkers, cognition in patients with cognitive impairment. In this prospective study, we enrolled 62 participants mild impairment or dementia January 2019 October 2020. All were assessed through tests, amyloid positron...
Various models of insomnia stress the role cognitive components, such as dysfunctional sleep-related beliefs, in maintenance and exacerbation insomnia. This study aimed to use network analysis identify particular beliefs that are central have strong associations with severity. In addition, we a relative importance map out predictive pathways between types
The ability of fine-tuning wavelengths in a high-Q resonance has been applied to various optical applications, particularly that the development nanoscaled, ultrathin photodetectors realize next-generation sensors. However, designing nanopatterned surface photodetector induce intriguing effects inevitably deteriorates electrical properties due increased roughness and defects, which cause significant recombination photogenerated carriers. Moreover, light absorption semiconductor fundamentally...
Various physiological and psychological functions are influenced by circadian typology (CT), which was reported to be related resilience. However, few studies have assessed the effects of CT in relation The aim present study assess influence on sleep-related symptoms, physical fatigue well-being included a total 1794 healthy hospital employees, they completed Morningness–Eveningness Questionnaire, Connor–Davidson Resilience Scale, Pittsburgh Sleep Quality Index, Epworth Sleepiness Fatigue...
This study aimed to examine the inter-method reliability and volumetric differences between NeuroQuant (NQ) Freesurfer (FS) using T1 volume imaging sequence with different slice thicknesses in patients mild cognitive impairment (MCI). retrospective enrolled 80 diagnosed MCI at our memory clinic. NQ FS were used for analysis of three-dimensional T1-weighted images thickness 1 1.2 mm. Inter-method was measured Pearson correlation coefficient (r), intraclass (ICC), effect size (ES). Overall,...
Background: Insomnia is prevalent among the general population, and studies have shown an increase in insomnia symptoms during novel coronavirus (COVID-19) pandemic. Despite numerous of insomnia, few investigated detail. In this study, we used network analysis to investigate interactions between population. Furthermore, given effect COVID-19 on mental health, also how anxiety response depression related symptoms. Methods: Data from 785 non-infected participants were used. The Severity Index...
To compare two clinically available MR volumetry software, NeuroQuant® (NQ) and Inbrain® (IB), examine the inter-method reliabilities differences between them.This study included 172 subjects (age range, 55-88 years; mean age, 71.2 years), comprising 45 normal healthy subjects, 85 patients with mild cognitive impairment, 42 Alzheimer's disease. Magnetic resonance imaging scans were analyzed IB NQ. Mean compared paired t test. Inter-method reliability was evaluated Pearson's correlation...
The purpose of the present study was to determine whether Internet overuse associated with empathic ability in college students. A total 261 participants (145 males and 116 females; mean age 21.93 years) completed Empathy Quotient (EQ), Young's Addiction Test (IAT), questionnaires about demographic data internet using patterns. Of these subjects, 85 (32.5%) were categorized as over-users. There no significant difference EQ score between over-user group average user group. had lower scores...
The present study compared cancer-related fatigue (CRF) and chronic syndrome (CFS) using multidimensional measurements with the aim of better understanding characteristics exploring markers two similar syndromes.Twenty-five patients CRF twenty CFS completed questionnaires, including Fatigue Severity Scale (FSS), Hospital Anxiety Depression (HADS), Perceived Stress (PSS), Pittsburgh Sleep Quality Index (PSQI). Additionally, levels high sensitivity C-reactive protein (hs-CRP), heart rate...
BACKGROUND Deep neuromuscular blockade (NMB) may reduce muscle injury and related inflammation. The inflammation is one of the pathophysiological processes peri-operative complications. OBJECTIVE To compare degree postoperative complications including delirium (POD) bleeding according to NMB during general anaesthesia for total hip replacement. DESIGN A prospective, single-blind, randomised controlled trial. SETTING Tertiary, university hospital, single centre. PATIENTS Eighty-two patients...
Background and Objective Insomnia symptoms are common in the general population. This study evaluated effects of melatonin-rich milk, which contains 10 times more melatonin than usual on insomnia symptoms. Methods Double-blind randomized placebo-controlled trial was performed. A total 91 subjects aged 21−69 years with mild were recruited from community. All underwent baseline studies for severity index, Pittsburgh sleep questionnaire Epworth sleepiness scale (ESS), Beck depression inventory...
This study explored whether temperament profiles are associated with psychological functioning and character maturity affects this association in patients panic disorders (PD).
