Tingting Tang(Tingting Tang),Somkiat Mansumitrchai(Somkiat Mansumitrchai ) KINFORMS 2022 Management Review Vol.17 No.2

The main focus of this paper is to determine the antecedents which significantly affect the attitude toward digital wallet adoption in the context of Chinese youth and to explore the moderating role of demographic and behavioral factors on the relationships between digital wallet adoption and its antecedents. The sample consists of 212 respondents. The multiple regression results indicated that perceived complexity and trialability have statistically significant relationships with digital wallet adoption. Moreover, the moderated regression analysis showed that the frequency of usage significantly moderates the relationship between the intention to adopt digital wallets and relative advantages. The findings of this study not only improve understanding of predictors affecting digital wallet adoption and behavioral differences influencing the degree of adoption but also provide insights for digital wallet service providers to redesign and develop their program to increase customer satisfaction rate.

Nitrogen self‑doped porous carbon nanosheets derived from azo dye flocs for efficient supercapacitor electrodes

Tingting Wei,Liang Wu,Feng Yu,Yin Lv,Long Chen,Yulin Shi,Bin Dai 한국탄소학회 2019 Carbon Letters Vol.29 No.5

The present work introduces a new method for the recycling of waste flocculation sludge to prepare electrode materials for supercapacitor. Hazardous azo dye was removal from textile dying wastewater by a new chitosan-based flocculant, and the generated dye sludge flocs was used as a nitrogen-containing precursor for the fabrication of N-doped carbon materials. The influence of azo dye on specific surface areas, nitrogen content, pore evolution of the resulting products and their electrochemical performance were investigated in detail. The results demonstrated a dual role of azo dye worked as both a nitrogen resource and pore-forming agent. The resulting N-doped carbon nanosheets derived from azo dye flocs demonstrated high electrochemical capacitance and good stability for supercapacitor electrode, which is attributed to the unique nitrogen doping, higher specific surface area and efficient charge transfer ability.

On compressive behavior of large welded hollow spherical joints with both internal and external stiffeners

Tingting Shu,Xian Xu,Yao-Zhi Luo 국제구조공학회 2023 Steel and Composite Structures, An International J Vol.46 No.2

Welded hollow spherical joints are commonly used joints in space grid structures. An internal stiffener is generally adopted to strengthen the joints when large hollow spheres are used. To further strengthen it, external stiffeners can be used at the same time. In this study, axial compression tests are conducted on four full-scale 550 mm spherical joints. The failure modes and strengths of the tested joints are investigated. It shows that the external stiffeners are able to increase the strength of the joint up to 25%. A numerical model for large spherical joints with stiffeners is established and verified against the experimental results. Parametric studies are executed considering six main design factors using the verified model. It is found that the strength of the spherical joint increases as the thickness, height and number of the external stiffeners increase, and the hollow sphere’s diameter has a neglectable effect on the enhancement caused by the external stiffeners. Based on the experimental and numerical results, a practical formula for the compressive bearing capacity of large welded hollow spherical joints with both internal and external stiffeners is proposed. The proposed formula gives a conservative prediction on the compressive capacity of large welded hollow spherical joints with both internal and external stiffeners.

Combinatorial Fine-Tuning of Phospholipase D Expression by Bacillus subtilis WB600 for the Production of Phosphatidylserine

( Tingting Huang ),( Xueqin Lv ),( Jianghua Li ),( Hyun-dong Shin ),( Guocheng Du ),( Long Liu ) 한국미생물 · 생명공학회 2018 Journal of microbiology and biotechnology Vol.28 No.12

Phospholipase D has great commercial value due to its transphosphatidylation products that can be used in the food and medicine industries. In order to construct a strain for use in the production of PLD, we employed a series of combinatorial strategies to increase PLD expression in Bacillus subtilis WB600. These strategies included screening of signal peptides, selection of different plasmids, and optimization of the sequences of the ribosome-binding site (RBS) and the spacer region. We found that using the signal peptide amyE results in the highest extracellular PLD activity (11.3 U/ml) and in a PLD expression level 5.27-fold higher than when the endogenous signal peptide is used. Furthermore, the strain harboring the recombinant expression plasmid pMA0911-PLD-amyE-his produced PLD with activity enhanced by 69.03% (19.1 U/ml). We then used the online tool \RBS Calculator v2.0 to optimize the sequences of the RBS and the spacer. Using the optimized sequences resulted in an increase in the enzyme activity by about 26.7% (24.2 U/ml). In addition, we found through a transfer experiment that the retention rate of the recombinant plasmid after 5 generations was still 100%. The final product, phosphatidylserine (PS), was successfully detected, with transphosphatidylation selectivity at 74.6%. This is similar to the values for the original producer.

A mean value function and its computational formula related to D. H. Lehmer's problem

Tingting Wang 대한수학회 2016 대한수학회보 Vol.53 No.2

Let $p$ be an odd prime and $c$ be a fixed integer with $(c, p)=1$. For each integer $a$ with $1\le a \leq p-1$, it is clear that there exists one and only one $b$ with $0\leq b \leq p-1$ such that $ab \equiv c \bmod p$. Let $N(c, p)$ denote the number of all solutions of the congruence equation $ab \equiv c \bmod p$ for $1 \le a, b \leq p-1$ in which $a$ and $\overline{b}$ are of opposite parity, where $\overline{b}$ is defined by the congruence equation $b\overline{b}\equiv 1 \bmod p $. The main purpose of this paper is using the mean value theorem of Dirichlet $L$-functions and the properties of Gauss sums to study the computational problem of one kind mean value function related to $E(c, p)=N(c, p)-\frac{1}{2}\phi(p)$, and give its an exact computational formula.

Nitrogen and Oxygen Co-doped Porous Carbon Fabric for Efficient Removal of Formaldehyde

Tingting Chen,Xiaosai Hu,Tao Zhao,Yuanyu Ge 한국섬유공학회 2022 Fibers and polymers Vol.23 No.7

Formaldehyde can pose a huge threat to human health due to its’ carcinogenic effect. Carbon materials asadsorbents are widely applied to remove formaldehyde hazards. However, most carbon materials with disadvantages of thelimited number of surface functional groups and the lack of suitable pore structure suffer from low adsorption rate for theadsorptive removal of formaldehyde. To improve the adsorption capability, oxygen (O) and nitrogen (N) elements co-dopedporous viscose-based activated carbon fiber (N-O-ACF) was prepared via oxidation-hydrothermal treatment. First of all, theO atom can be introduced into ACF through chemical oxidation. Then, with the help of the O atom bridging effect, N atomscan be efficiently incorporated into ACF, and the content of the N element is as high as 7.13 wt.%. Thus, an improvedadsorption performance of N-O-ACF for formaldehyde removal was achieved with the support of the synergistic effect of Nand O elements. The adsorption capacity of N-O-ACF for removing formaldehyde increased up to 226 mg g-1, while only161.5 mg g-1 was obtained for original ACF. The excellent formaldehyde adsorption capacity indicates that N-O-ACF may bea promising adsorbent in the field of indoor air purification.

중국부동산 보유세제에 대한 시사점 - 한ㆍ중 비교를 중심으로 -

( Tingting Ni ),옥무석 ( Moo-seok Ok ) 이화여자대학교 법학연구소 2021 法學論集 Vol.26 No.2

새 중국 성립초기부터 중국은 부동산세에 대한 입법을 시작하였으며 1986년 국무원에서 「방산세임시조례」(房産稅暫行條例)를 통과하였으며 1988년에는 「도시토지사용세임시조례」(城鎭土地使用稅暫行條例)를 통과하였다. 이는 개혁개방 후 중국에서는 새로운 부동산세에 대한 법률제도가 구축하기 시작하였음을 의미한다. 하지만 날로 빈부격차가 심화되고 부의 비중에서도 부동산이 차지하는 비중이 상당히 높은 반면 중국에서는 개인소유의 비경영성 주택에 대한 보유세를 징수하지 않는 것이 사회에 불공정을 초래하였으며 이는 부동산 조세제도로 부의 재분배 기능을 요구하고 있다. 그리하여 2011년부터 상하이와 충칭에서 방산세 개혁이 먼저 시작되었고 이번 개혁의 핵심은 주민의 개인주택의 보유단계에 대한 방산세의 부과이며 현재 오직 상하이와 충칭에만 소규모적으로 시범이 있을 뿐 다른 지역에는 부과되지 않았다. 또한 2021년 10월, 전국인민대표대회 상무위원회에서는 국무원에 부분 지역에 대한 「방지산세」(房地産稅)개혁의 시범을 수권하였으며 이로써 향후 중국에서는 점차적으로 더 많은 도시에서 부동산 보유세에 대한 시범을 실시할 것이다. 따라서 실시된 현 시범도시의 방산세와 한국의 종합부동산세에 대한 비교ㆍ분석을 통하여 중국 부동산보유세에 대한 시사점을 제시하였다. From the beginning of the establishment of a new China, China began legislation on real estate taxes, passed <房産稅暫行條例> by the State Council in 1986, and passed <城鎭土地使用稅暫行條例> in 1988. This means that after reform and opening up, a legal system for new real estate taxes began to be established in China. However, the gap between the rich and the poor is widening day by day, and real estate accounts for a fairly high proportion of wealth. On the other hand, in China, not collecting ownership tax on privately owned non-management housing caused unfairness to society, which requires the redistribution of wealth through the real estate tax system. In 2011, real estate tax reform began in Shanghai and Chongqing. The core of this reform is taxation on the possession of private housing by residents. Currently, only Shanghai and Chongqing have small-scale demonstrations and have not been imposed in other regions. In addition, in October 2021, the Standing Committee of the National People's Congress granted the State Council a demonstration of the partial region. As a result, China will gradually demonstrate real estate ownership taxes in more cities in the future. Therefore, implications for the Chinese real estate ownership tax were presented through comparison and analysis of the defense tax in the current pilot real estate tax and the comprehensive real estate tax in Korea.

Seasonal Variation and Sources of Heavy Metals in Urban Street Dusts and River Sediments of Dongluo River Watershed in Ji’nan City, China

Tingting Duan,Shanjun Liu,Dongying Wang,Jiashen Feng,Ningning Song,Yanxin Yu,Yingxia Li 대한토목학회 2020 KSCE Journal of Civil Engineering Vol.24 No.5

Due to intense human activities, urban street dusts and river sediments are usually polluted by heavy metals. This study investigated the seasonal variations (summer and winter) of pollution level, spatial distribution and potential sources of heavy metals in street dusts (SD) and river sediments (RS) of Dongluo River watershed, Ji’nan, China. Results showed cadmium (Cd), chromium (Cr), copper (Cu), lead (Pb) and zinc (Zn) contents were 3.5 (8.6), 3.0 (1.4), 4.9 (2.6), 4.1 (1.1) and 3.9 (4.0)-fold of their geochemical soil background values (BGV) of Shandong Province, China in summer (winter). Mercury (Hg) and arsenic (As) contents were lower than their background values in both summer and winter. The differences of Cd, Cr, Cu, Pb, Zn, Mn and As contents in river sediments between winter and summer were not statistically significant. The correlation coefficients between metal contents and the distance between sampling sites and the east-west boundary of study area were higher in summer than those in winter. Based on principal component analysis (PCA) and multivariate linear regression (MLR), coal combustion and traffic-related sources were the main sources in winter, and agricultural activities and traffic-related sources were the main sources in summer.
