Purpose: During and after Covid-19 pandemic, technology has emerged as a key factor in supporting the recovery of the economy and the rise of living standards. This study examines seven factors affecting the intention of food delivery apps usage, which include Performance Expectancy, Effort Expectancy, Social Influence, Hedonic Motivation, Price Value, and Habit, and how much influence they have on the customers' behavioral continuance of food delivery apps after Covid-19 Pandemic. Research methodology: This research is a quantitative descriptive research with 473 qualified respondents from 550 respondents collected. Besides using the UTAUT2 model (Venkatesh et al., 2012), Information Quality was added to give a better explanation for the consumers’ intention towards continuance behavior using food delivery apps. The collected data is then processed using SPSS 22.0. Results: Habit factors and Information Quality factors have significant positive effects on promoting food delivery apps usage intention, which in turn influences continuance behavior. In addition, Habit factors and Information Quality factors together have an effect of 48.57% on Behavioral Intention. Conclusion: The result proves that positive habits and food information quality can increase the usage intention towards the behavioral continuance of consumers. Higher usage frequency can be improved by increasing these two factors.

Helix Nucleation via Hydrocarbon Cross-link Mimicking N-capping Box
Luong Thuy Nguyen,Huy Xuan Luong,김영우 대한화학회 2016 Bulletin of the Korean Chemical Society Vol.37 No.4
The N-capping box is a well-known helix-stabilizing motif with a distinct reciprocal backbone–side chain hydrogen-bonding arrangement at the N-terminus of helices. This unique N-terminal flanking motif consists of a hydrogen-bonded cycle of four amino acid residues in which the backbone amide of the N3 residue forms a hydrogen bond with the side chain of the Ncap residue, and reciprocally, the side chain of the N3 accepts a hydrogen from the Ncap amide. In this study, as a new helix-stabilizing strategy, we examined a metathesis-based cross-linking system that mimics the hydrogen bond between the Ncap amide and the side chain of the N3 at the N-terminus. Using this new system, we prepared two alanine/lysine-based model peptides and analyzed its impact on helix stabilization. We found that a 16-membered macrocycle incorporated by ring-closing metathesis effectively induces and stabilizes helical conformations of the given model sequence.

Two new species of Camellia (Theaceae) are described from Vietnam: Camellia vuquangensis Luong, Tran & L. T. Nguyen and Camellia hatinhensis Luong, Tran & L. T. Nguyen. The new taxa were col- lected from Vu Quang National Park in the center of Vietnam. The new finds are morphologically dissimilar to all known Camellia species. Recent Camellia discoveries have increased the number of species recorded in Viet- nam from 50 to 75, making Vietnam a center of diversity and a crucial area for more research into the diversity and distributions of Camellia.
Energy Join Quality Aware Real-time Query Scheduling Algorithm for Wireless Sensor Networks
( Luong Thi Thu Phuong ),( Sungyoung Lee ),( Young-koo Lee ) 한국정보처리학회 2011 한국정보처리학회 학술대회논문집 Vol.18 No.1
Nowadays, the researches study high rate and real-time query applications seem to be real-time query scheduling protocols and energy aware real time query protocols. Also the WSNs should provide the quality of data in real time query applications that is more and more popular for wireless sensor networks (WSNs). Thus we propose the quality of data function to merge into energy efficiency called energy join quality aware real-time query scheduling (EJQRTQ). Our work calculate the energy ratio that considers interference of queries, and then compute the expected quality of query and allocate slots to real-time preemptive query scheduler.
