Project Based Learning for University-Led Urban Regeneration: A Case Study on the Strategic Communication Campaign Class for the Sinchon Regeneration Project
(2020)The purpose of this study is to examine the effectiveness of PBL in a college AD/PR class. This class was run under the theme of 'Sinchon Regeneration Project' in the 'Seodaemun-gu & University Collaborative Project Program'. ... -
The Effectiveness of Jeju Island Mixed Reality Tourism Application: Focusing on the Moderating Role of Users' K-Culture Involvement
(2020)In this study, we introduce a multi-modal mixed reality (MR) application for advertising the main touristic landmarks on Jeju Island, and evaluate its effectiveness based on the Technology Acceptance Model (TAM) with a ... -
A Comparative Study on the Performance of GSCA and CSA in Parameter Recovery for Structural Equation Models With Ordinal Observed Variables
(2018)simulation based comparative study was designed to compare two alternative approaches to structural equation modeling—generalized structured component analysis (GSCA) with the alternating least squares (ALS) estimator ... -
Generalized Structured Component Analysis with Uniqueness Terms for Accommodating Measurement Error
(2017)Generalized structured component analysis (GSCA) is a component-based approach to structural equation modeling (SEM), where latent variables are approximated by weighted composites of indicators. It has no formal mechanism ... -
Detecting Conditional Dependence Using Flexible Bayesian Latent Class Analysis
(2020)A fundamental assumption underlying latent class analysis (LCA) is that class indicators are conditionally independent of each other, given latent class membership. Bayesian LCA enables researchers to detect and accommodate ... -
BlocklyAR: A Visual Programming Interface for Creating Augmented Reality Experiences
(2020)State-of-the-art tools for creating augmented reality (AR) applications often depend on a specific programming language and the deployed target devices. The typing syntax of a program is error-prone, and device dependency ... -
Application of IRT Models to Selection of Bidding Paths in Financial Transmission Rights Auction: U.S. New England
(2020)This paper explores a way to apply Item Response Theory (IRT), one of the popular statistical methodologies in measurement and psychometrics, to evaluate Financial Transmission Rights (FTR) paths in the U.S. electricity ... -
Monitoring of Heart Rate from Photoplethysmographic Signals Using a Samsung Galaxy Note8 in Underwater Environments
(2019)Photoplethysmography (PPG) is a commonly used in determining heart rate and oxygen saturation (SpO2). However, PPG measurements and its accuracy are heavily affected by the measurement procedure and environmental factors ... -
PalmitoAR: The Last Battle of the U.S. Civil War Reenacted Using Augmented Reality
(2020)Various efforts are used to preserve American history including relying on formal education, distributing information (text, video or visual aids) on social channels, displaying artifacts in historical centers or more ... -
Meet the Virtual Jeju Dol Harubang—The Mixed VR/AR Application for Cultural Immersion in Korea’s Main Heritage
(2020)Jeju Island comes second to only Seoul as Korea’s most visited destination, yet most visitors do not have the chance to go beyond brief visits and immerse themselves in the island’s history and cultural heritage. This ... -
Underused Methods in Developmental Science to Inform Policy and Practice
(2020)In this article, we offer recommendations for underused innovations and advances in research methods to enhance the quality of developmental science research. We couch our recommendations in terms of measurement innovations, ... -
Reflection on modern methods: planned missing data designs for epidemiological research
(2020)Taking advantage of the ability of modern missing data treatments in epidemiological research (e.g. multiple imputation) to recover power while avoiding bias in the presence of data that is missing completely at random, ... -
Global divergent responses of primary productivity to water, energy, and CO2
(2019)The directionality of the response of gross primary productivity (GPP) to climate has been shown to vary across the globe. This effect has been hypothesized to be the result of the interaction between multiple bioclimatic ... -
Global photosynthetic capacity is optimized to the environment
(2019)Earth system models (ESMs) use photosynthetic capacity, indexed by the maximum Rubisco carboxylation rate (Vcmax), to simulate carbon assimilation and typically rely on empirical estimates, including an assumed dependence ... -
Short-term thermal acclimation of dark respiration is greater in non-photosynthetic than in photosynthetic tissues
(2019)Thermal acclimation of plant respiration is highly relevant to climate projections; when included in models, it reduces the future rate of atmospheric CO2 rise. Although all living plant tissues respire, few studies have ... -
Warming increases the sensitivity of seedling growth capacity to rainfall in six temperate deciduous tree species
(2018)Predicting the effects of climate change on tree species and communities is critical for understanding the future state of our forested ecosystems. We used a fully factorial precipitation (three levels; ambient, −50 % ... -
Pyrogenic Carbon Increases Pitch Pine Seedling Growth, Soil Moisture Retention, and Photosynthetic Intrinsic Water Use Efficiency in the Field
(Frontiers, 2020)Climate change and land management are altering forest fire frequency and intensity worldwide. In some Northeast U.S. forests, pitch pine (Pinus rigida Miller) is not suffering from presence but rather a lack of wildfire ... -
P-model v1.0: an optimality-based light use efficiency model for simulating ecosystem gross primary production
(Copernicus Publications, European Geosciences Union, 2020)Terrestrial photosynthesis is the basis for vegetation growth and drives the land carbon cycle. Accurately simulating gross primary production (GPP, ecosystem-level apparent photosynthesis) is key for satellite monitoring ... -
A reporting format for leaf-level gas exchange data and metadata
(Elsevier, 2021)Leaf-level gas exchange data support the mechanistic understanding of plant fluxes of carbon and water. These fluxes inform our understanding of ecosystem function, are an important constraint on parameterization of ... -
Assessing the role of trap-to-band impact ionization and hole transport on the dark currents of 4H-SiC photoconductive switches containing deep defects
(AIP, 2016)Simulation studies of the electrical response characteristics of 4H-SiC switches containing traps are reported in the absence of photoexcitation. The focus is on trap-to-band impact ionization and the role of hole injection ...
