Purpose: This study examines the relationship between content characteristics and customer viewing and purchase intention in live-streaming commerce. Research design, data, and methodology: For this purpose, seven independent factors such as entertainment, artistry, storytelling, informativity, interactivity, reliability, and technicality are extracted based on previous literature. The viewing intention and purchase intention are adopted as dependent factors. The role of ‘immersion’ is investigated as a mediating factor between the independent and dependent factors. Results: The results showed that entertainment, artistry, technicality, and reliability significantly affected immersion, and immersion affected viewing intention and purchase intention. Immersion was found to play a mediating role between content characteristics and consumer viewing and purchase intention. Conclusions: The results indicate that the content characteristics not only attract customers but also affect their immersion, viewing intention, and purchase intention directly or indirectly in the live-streaming commerce sector.

Biosynthesis of resveratrol glucosides compounds by amylosucarse DgAS

Samir Bahadur Thapa,Purna Bahadur Poudel,Jae Kyung Sohng 한국당과학회 2022 한국당과학회 학술대회 Vol.2022 No.07

A highly efficient biocatalytic system was constructed to make bioactive resveratrol poly-glucosides in a chain by using sucrose as a cheap source of UDP-glucose donors with the help of amylosucrase, DgAS from Deinococcus geothermalis. The system is superior as the reaction is very fast, direct, high rate of conversion of substrates to products, high thermostable, and regio-stereospecific with very effective in action at 40°C. Successfully our system can convert around 98% resveratrol to its resveratrol glucosides in a short time. The amylosucrase DgAS not only added glucose in multiple hydroxyl positions but also conjugates glucose in the chain as a result highly soluble glucosylated products are formed. Because of the highest thermostability and specific action among all known amylosucrases (ASases), DgAS has proven its importance for the transglucosylation activities in different polyphenols on an industrial scale. Therefore, our system can be used industrially for the cost-effective production of resveratrol glucosides.

Purpose: This study aimed to compare the safety and efficacy of tamsulosin and tadalafil as medical expulsive therapy for distal ureteral stones. Materials and Methods: This prospective randomized study was conducted at the Department of Urology of Bir Hospital over a period of 12 months in patients with distal ureteral stones sized 5 to 10 mm. Patients were randomly divided into 2 groups: group A received tamsulosin 0.4 mg and group B received tadalafil 10 mg at bedtime for 2 weeks. Stone expulsion rate, number of ureteric colic episodes and pain score, analgesic requirements, and adverse drug effects were noted in both groups. Statistical analyses were performed by using Student t-test and chi-square test. Results: Altogether 85 patients, 41 in group A and 44 in group B, were enrolled in the study. The patients' average age was 31.72±12.63 years, and the male-to-female ratio was 1.5:1. Demographic profiles, stone size, and baseline investigations were comparable between the 2 groups. The stone expulsion rate was significantly higher in the tadalafil group than in the tamsulosin group (84.1% vs. 61.0%, p=0.017). Although the occurrence of side effects was higher with tadalafil, this difference was not significant (p=0.099). There were no serious adverse effects. Conclusions: Tadalafil has a significantly higher stone expulsion rate than tamsulosin when used as a medical expulsive therapy for distal ureteral stones sized 5–10 mm. Both drugs are safe, effective, and well tolerated with minor side effects.

The defect-free transfer of graphene grown by using chemical vapor deposition is essential for its applications to electronic devices. For the reduction of inevitable chemical residues, such as polar molecules and ionized impurities resulting from the transfer process, a hydrophobic polydimethylsiloxane (PDMS) film was coated on a SiO2/Si wafer. The hydrophobic PDMS film resulted in fewer defects in graphene in comparison to a bare SiO2/Si wafer, as measured with Raman spectroscopy. We also studied the influence of the hydrophobic PDMS film on the chemical doping of graphene. Here, nitric acid (HNO3) was used to make p-type graphene. When graphene was transferred onto a SiO2/Si wafer coated with the hydrophobic PDMS film, fewer defects, compared to those in graphene transferred onto a bare SiO2/Si wafer, were created in grapheme by HNO3 as measured with Raman spectroscopy. The experiments suggest that when graphene is transferred onto a hydrophobic film, the number of defects created by chemical molecules can be reduced.

Insight of cleaning, doping and defective effects on the graphene surface by using methanol

Rai, Krishna Bahadur,Khadka, Ishwor Bahadur,Koirala, Agni Raj,Ray, Schindra Kumar Techno-Press 2021 Advances in materials research Vol.10 No.4

Graphene has attracted enormous interest to researchers because of its remarkable electrical, mechanical, and optical properties. Chemical vapor deposition (CVD) method was used to synthesize the graphene. The methanol (CH₃OH) was used to investigate the cleaning, doping and defective effect in the graphene surface. The samples were characterized by X-ray diffraction patterns (XRD), field emission scanning electron microscope (FESEM) images, Xray photoelectron spectroscopy (XPS) measurements, and Raman spectroscopy. XRD indicates the introduction of oxygen in graphene layer. FESEM images of samples suggest the sheet like morphology. XPS measurements confirm the existence of large number of oxygen containing functional groups (C=O, COOH, and C-O) and C-C in the graphene surface. The Raman spectra confirm the n-doping and cleaning effects on graphene surface through the red shifts of G and 2D peaks. Furthermore, the optical images were used to observe the residues in graphene. The residues are obtained due to adsorption of CH₃OH in graphene surface. Therefore, this work provides a simple and effective approach to investigate the cleaning, doping and defective effects on the surface of graphene using CH₃OH solvent that can be applied in tunable electronic devices and gas sensor.

Sher Bahadur Gurung,Franz Kevin F. Geronimo,최혜선,홍정선,김이형 한국습지학회 2018 한국습지학회지 Vol.20 No.1

Nutrients generated from various land uses lead to eutrophication during the influx of water, and it is necessary to apply the LID techniques to reduce nutrients from nonpoint sources in order to mitigate the occurrence of the algal bloom. This study was carried out to derive the design factors of hybrid artificial wetland (HCW) to increase the removal efficiency of nutrients. HCW system was constructed in the year 2010 for the treatment of rainfall runoffs from parking lots and roads composed of 100% impervious floors in the Cheonan campus of Kongju University. The average nutrients removal efficiency of TN and TP was 74% and 72%, respectively. Both TN and TP removal efficiencies were higher than those of free surface wetlands and subsurface flow wetlands due to activated physical and ecological mechanisms. The critical design parameters for the efficient nutrients removal in the artificial wetlands were the ratio of the surface area to the catchment area (SA/CA), land use, the rainfall runoff, and the rainfall intensity. The optimal carbon to nitrogen (C/N) ratio was estimated at 5: 1 to 10.3: 1. The results of this study can be applied to the efficient design of hybrid artificial wetlands to treat nutrients in urban runoff with high efficiency.

Type III polyketide synthase (PKS) found in bacteria is known as 1,3,6,8-tetrahydroxynaphthalene synthase (THNS). Microbial type III PKSs synthesize various compounds that possess crucial biological functions and significant pharmaceutical activities. Based on our sequence analysis, we have identified a putative type III polyketide synthase from Nocardia sp. CS682 was named as ThnA. The role of ThnA, in Nocardia sp. CS682 during the biosynthesis of 1,3,6,8 tetrahydroxynaphthalene (THN), which is the key intermediate of 1-(α-L-(2-O-methyl)-6-deoxymannopyranosyloxy)-3,6,8- trimethoxynaphthalene (IBR-3) was characterized. ThnA utilized five molecules of malonyl-CoA as a starter substrate to generate the polyketide 1,3,6,8-tetrahydroxynaphthalene, which could spontaneously be oxidized to the red flaviolin compound 2,5,7-trihydroxy-1,4-naphthoquinone. The amino acid sequence alignment of ThnA revealed similarities with a previously identified type III PKS and identified Cys¹³⁸, Phe¹⁸⁸, His²⁷⁰, and Asn³⁰³ as four highly conserved active site amino acid residues, as found in other known polyketide synthases. In this study, we report the heterologous expression of the type III polyketide synthase thnA in S. lividans TK24 and the identification of THN production in a mutant strain. We also compared the transcription level of thnA in S. lividans TK24 and S. lividans pIBR25-thnA and found that thnA was only transcribed in the mutant.

네팔은 중국과 인도 사이에 위치한 남부 아시아의 내륙국가로 폐수관리는 도시지역에서 가장 중요한 문제 중 하나이 다. 네팔의 폐수처리 시스템은 비싼 운영비, 불연속적인 전력 공급, 유지관리 및 기술인력의 부족으로 인해 조성과 운 영이 어렵다. 이러한 이유로 인공습지는 폐수처리시설의 대안기술로써 다양한 지역에 적용되고 있다. 일반적으로 인공 습지 기술의 효율 지속 가능성은 적절한 운영과 유지관리 및 적극적인 지역사회 참여에 의존한다. 따라서 본 연구에서 는 26개의 인공습지에서의 제거 효율, 방류수질, 네팔 수질기준, 운영 및 유지관리 활동 등을 조사하고 문제점을 분석 하여 관리방안 등을 도출하였다. 오염물질당 제거효율은 ka-1의 인공습지가 가장 높은 것으로 나타났으며, B-1, L-3, Ka-5, k-1 순으로 높은 것으로 나타났다. 네팔의 인공습지 조성기술은 최근 20년간 기술개발 없이 전통적 방식에 의 존해온 결과 비효율적인 성능으로 인해 많은 습지가 가동이 중단되거나 폐쇄되는 것으로 나타났다. 또한 기술개발의 부족, 자연재해, 대중의 인공습지에 대한 낮은 인식 및 예산 부족 등은 인공습지의 지속적인 개발을 저해하고 있는 것 으로 조사되었지만, 인공습지는 네팔 도시지역의 폐수문제에 대한 해결방안으로 고려되고 있다. Nepal is a landlocked mountainous country in South Asia, located between China to the north and India to the south, east, and west. As such, wastewater management has become one of the most significant problems in urban area of Nepal. In Nepal, the centralized wastewater treatment systems were dysfunctional due to high cost of operation, discontinuous power supply, lack of proper maintenance and proper technical workforce to address the issues. As such, constructed wetlands (CW) were applied to treat various secondary wastewater as alternative to wastewater treatment facilities. Generally, efficiency and sustainability of CW technology depends on proper operation and maintenance and active community involvement. This study summarizes information about 26 CW in Nepal. Specifically, factors including data banking, removal efficiency, quality of discharged water, compliance to water quality standard of Nepal and operation and maintenance were investigated. Considering removal efficiency per pollutant, Ka-1 achieved the greatest reduction for most pollutant followed by B-1, L-3, Ka-5 and K-1. Nepal has practiced CW technology for more than 2 decades but currently, development of technology was interrupted by the inefficient performance of existing facilities. Public awareness about the technology, natural disaster, unavailability of specified substrate materials, lack of fund for further research and experiments has hindered the expansion of technology. In spite of these concerns, CW was still proven as an alternative solution to the present wastewater problems in urban areas of Nepal.
