Uncovering round-trip patterns in bicycle sharing
Analyzing neighborhood-level bicycle usage is pivotal for developing effective policies and promoting bicycle-friendly initiatives. Although data from bicycle sharing systems (BSS) have become increasingly accessible, round-trip travel remains underexamined compared to one-way or last-mile commuting trips. This study addresses that gap by investigating round-trip usage in Seoul's BSS, which adopts a low-cost, flat-rate fare structure that encoura…

Uncovering Covid-19 transmission tree
Introduction: This paper presents a comprehensive analysis of COVID-19 transmission dynamics using an infection network derived from epidemiological data in South Korea, covering the period from January 3, 2020, to July 11, 2021. The network illustrates infector-infectee relationships and provides invaluable insights for managing and mitigating the spread of the disease. However, significant missing data hinder conventional analysis of such netwo…
How Avatar Identification Affects Enjoyment in the Metaverse
Despite growing interest in studying the metaverse, a theory-driven investigation into the factors that contribute to an enjoyable metaverse experience remains scarce. The current study examined the impacts of avatar identification, social engagement, and avatar customization on users' enjoyment of the metaverse based on the impression management theory. A total of 301 metaverse users were recruited for the study. The hypothesized models of media…
Psychometric Properties for Multidimensional Cognitive Load Scale in an E-Learning Environment
(1) Background: A learner's cognitive load in a learning system should be effectively addressed to provide optimal learning processing because the cognitive load explains individual learning differences. However, little empirical research has been conducted into the validation of a cognitive load measurement tool (cognitive load scale, i.e., CLS) suited to online learning systems within higher education. The purpose of this study was to evaluate …
Impacts of Thresholds of Gray Value for Cone-Beam Computed Tomography 3D Reconstruction on the Accuracy of Image Matching with Optical Scan
In cone-beam computed tomography (CBCT), the minimum threshold of the gray value of segmentation is set to convert the CBCT images to the 3D mesh reconstruction model. This study aimed to assess the accuracy of image registration of optical scans to 3D CBCT reconstructions created by different thresholds of grey values of segmentation in partial edentulous jaw conditions. CBCT of a dentate jaw was reconstructed to 3D mesh models using three diffe…
Accounting for Fairness in a Two-Stage Stochastic Programming Model for Kidney Exchange Programs
Kidney exchange programs, which allow a potential living donor whose kidney is incompatible with his or her intended recipient to donate a kidney to another patient in return for a kidney that is compatible for their intended recipient, usually aims to maximize the number of possible kidney exchanges or the total utility of the program. However, the fairness of these exchanges is an issue that has often been ignored. In this paper, as a way to ov…
