To investigate addiction, performed self-report questionnaires that assessed following items: functions mostly used,...

Recent deep-learning based synthetic computed tomography (sCT) generation using magnetic resonance (MR) images have shown promising results. However, generating sCT for the abdominal region poses challenges due to patient motion, including respiration and peristalsis. To address these challenges, this study investigated an unsupervised learning approach a transformer-based cycle-GAN with structure-preserving loss cancer patients. A total of 120 T2 MR scanned by 1.5 T Unity MR-Linac their...

The examined role playing (RPG), real-time strategy (RTS), first person shooting (FPS), sports games. Behavioral patterns play, academic performance, player characteristics assessed.The that...

Theta-phase gamma-amplitude coupling (TGC) measurement has recently received attention as a feasible method of assessing brain functions such neuronal interactions. The purpose this electroencephalographic (EEG) study is to understand the mechanisms underlying deficits in attentional control children with deficit/hyperactivity disorder (ADHD) by comparing power spectra and TGC at rest during mental arithmetic task.Nineteen-channel EEGs were recorded from 97 volunteers (including 53 subjects...

Social network analysis has emerged as a promising tool in modern social psychology. This method can be used to examine friend-based relationships terms of theory, with nodes representing individual students and ties between (e.g., friendships kinships). Using analysis, we investigated whether greater severity ADHD symptoms is correlated weaker peer among elementary school students.A total 562 sixth-graders from two schools (300 males) provided the names their best friends (maximum 10...

The Children's Depression Rating Scale-Revised (CDRS-R) is a valid instrument for the assessment of depressive symptoms in youth, but this measure yet to be validated Korea.
