The importance of non-face-to-face tourism is growing due to the impact COVID-19, and VR (virtual reality) attracting attention as a solution this need. This research investigates antecedents utilitarian hedonic values based on experience identifies relations between user visit intention. We performed an empirical study with data collected from 207 respondents major online communities. results show value be information access, flow, interactivity; whereas are interactivity, telepresence....

The effects of α- and β-cyclodextrins (CDs) on the twisted intramolecular charge transfer (TICT) emission p-(N,N-diethylamino)benzoic acid (DEABA) in aqueous solution have been investigated by using steady-state time-resolved fluorescence techniques. ratio TICT to normal increases as β-CD concentration increases, while it decreases significantly upon addition α-CD. This behavior is accordance with CD dependent decay times emissions, indicating formation different 1:1 DEABA/CD inclusion...

An excess of reactive oxygen species (ROS) relative to the antioxidant capacity causes oxidative stress, which plays a role in development Parkinson's disease (PD). Because mitochondria are both sites ROS generation and targets damage, delivery antioxidants might prevent or alleviate PD. To transduce protein human metallothionein 1A (hMT1A) into mitochondria, we computationally designed cell-penetrating artificial mitochondria-targeting peptide (CAMP). The recombinant CAMP-conjugated hMT1A...

The emergence of cancer immunotherapies, notably immune checkpoint inhibitors, has revolutionized anti-cancer treatments. These treatments, however, have been reported to be effective in a limited range cancers and cause immune-related adverse effects. Thus, for broader applicability enhanced responsiveness solid tumor immunotherapy, immunomodulation the microenvironment is crucial. Transforming growth factor-β (TGF-β) implicated reducing immunotherapy by promoting M2-type differentiation...

Static and fatigue mechanical properties of a polyamide-6 reinforced with 20% weight fraction short carbon fibers (PA6-20CF) material were investigated by means static tensile tests on both unnotched notched specimens. SEM pictures also taken the fracture surface specimens tested under static, low cycle failure (LCF) high (HCF) conditions, allowing to correlate cycles deformation pattern polymer matrix. Accordingly, two strain-approach-based models developed allowed accounting for different...

This study introduces an example-based chat-oriented dialogue system with personalization framework using long-term memory. Previous representative chat-bots use simple keyword and pattern matching methodologies. To maintain the quality of systems, generating numerous heuristic rules human labour is inevitable. The language expert knowledge also necessary to build those patterns. avoid high annotation cost, management adopted for building system. We propose three features: POS-tagged tokens...

To investigate the long-term efficacy and safety of posterior chamber implantable collamer lens (ICL) implantation in high myopia, risk factors associated with endothelial cell loss (ECL) or cataract development. Medical records 66 eyes 37 patients who underwent ICL for myopia were retrospectively analyzed a mean follow-up 12 years. Changes LogMAR best corrected visual acuity (BCVA), intraocular pressure (IOP), refractive power, density (ECD) over time incidence IOP elevation. Risk their...

This study investigates the impact of Primary Dealer (PD) obligation enhancement, introduced in October 2010 as part “Government Bond On-Exchange Trading Activation Plan,” on government bond market liquidity. Although policy aimed to strengthen liquidity, empirical analysis its effectiveness has been limited. Using both on-exchange and over-the-counter (OTC) transaction data from 2003 2024, controlling for key macroeconomic variables, applies a conditional heteroskedasticity model examine...

Floor mats are commonly used to improve the impact sound performance of existing homes, but actual reductions do not consistently appear, as they depend on test-bed conditions determine performance. Therefore, this study evaluated effects environmental test bed reduction performances different floor mats. The Korean industrial standard KS F 2865 specifies measurement method in room and sets thickness range available target structure bare slabs with thicknesses ranging from 120 mm 210 mm....

We show that an atomic system in a periodically modulated optical trap displays ideal mean-field symmetry-breaking transition. The symmetry is broken with respect to time translation by the modulation period. describe experimental observations and develop full microscopic theory of observed critical phenomena. transition explained as resulting from interplay long-range interatomic interaction nonequilibrium fluctuations strongly system. observations, including anomalous phase, are fully...

Electric-field-induced low-volume liquid ejection under ambient conditions was realized at a low bias potential of 12 V via nanopipette (aperture diameter 30 nm) combined with non-contact, distance-regulated (within 10 quartz tuning fork-atomic force microscope. A capillary-condensed water meniscus, spontaneously formed in the tip–substrate nanogap, reduces barrier by four orders magnitude, facilitating nanoliquid and subsequent transport/dispersion onto substrate without contact damage from...

In this research, we studied the effect of plasma treatment on optical/structural properties deoxyribonucleic acid (DNA) extracted from salmon sperm. DNA-cetyltrimethylammonium (CTMA) films were obtained by complexation DNA with CTMA. Circular dichroism (CD) and Raman spectra indicated that retained its double helical structure in solid film. The exhibited several vibration modes corresponding to nuclear bases deoxyribose-phosphate backbones DNA, as well alkylchains...

e-Transformation in container ports means port organization-wide innovative transformation encompassing internal and external value chains based on information communication technology. There is a considerable theoretical literature the impact of business performance, but there very little empirical study its effectiveness ports. The objective this paper to empirically investigate how management can influence customer satisfaction competitiveness. findings reveal that affect competitiveness...

Molecular detection of pathogens in clinical samples often requires pretreatment techniques, including immunomagnetic separation and magnetic silica-bead-based DNA purification to obtain the purified pathogens. These two techniques usually rely on handling small tubes containing a few millilitres sample manual operation, implying that an automated system encompassing both is needed for larger quantities samples. Here, we report three-dimensional (3D)-printed millifluidic platform enables...
