WEI Tingting 이화여자대학교 아시아여성학센터 2015 이화여자대학교 아시아여성학센터 학술대회자료집 Vol.2015 No.1

In 1995, the United Nations Fourth World Conference on Women was held in Beijing. This was in some ways a turning point for women’s movements internationally. Unprecedented international governmental commitments were made to gender equality with the Beijing Platform for Action. An unprecedented number of activists and advocates came together to discuss, debate and mobilize around gender issues. Chinese governmental and non-governmental participants played a central role in this forum. The Beijing women’s conference had a lasting impact in China. For this conference, LGBT (especially lesbian) people from different places in the world came to China. It had a remarkable and meaningful influence on China as it was the first time Chinese lesbian groups connected with the global gender and lesbian movement. There was a Lesbian Tent at the conference, and lesbian and gay activists who couldn’t participate in the conference organized a party inviting global lesbian activists. It was the first time for Chinese official and nongovernmental participants to get to know and understand lesbian issues. I combine interviews with conference participants (including participants from women’s organizations) with a documentary to review and narrate the 1995 stories. I show the connections between the Beijing Conference and the development of Chinese lesbian groups; I explore the spread and impact of gender awareness in Chinese lesbian communities who started to advocate for “lesbian rights as human rights”; I discuss how lesbian communities and women’s NGOs came to see, know, work with each other in the last 20 years; and the achievements made through subsequent processes.

Three-dimensional Microstructure Characterization of Loess from South Jingyang Plateau, China

( Tingting Wei ),( Wen Fan ) 대한지질공학회 2019 대한지질공학회 학술발표회논문집 Vol.2019 No.2

The loess collapsibility and permeability are primarily controlled by the microstructure. This microstructural investigation of loess (L1 and S2) on the Loess Plateau in China is based on X-ray micro-computed tomography. The 3D microstructural features of particles and pores are quantitatively studied by analyzing statistical parameters. A total of 92% of the particles have sphericity that lies in the range between 0.5 and 0.9, the aspect ratio of 93% particles is between 0.3-0.7. 67% of the particles are oriented between 0°- 45° (the angle between the long axis of the grain and the horizontal plane). Loess exhibits complex pore structures and obvious anisotropy, as reflected by dense networks, wide pore size ranges and different pore throat radii and frequencies at different dip angles. From L1 to S2, the structure tends to become more compact, the pore size tends to decrease, and the connectivity tends to weaken. Pore structure, which provides space for water movement, has a profound influence on the mechanical behavior of soil, and the relationship between permeability and pore structure is discussed. The results demonstrate the positive role that the pore (>13 μm) proportion, pore connectivity and pore throat radius play in permeability. Both the pore throat radius and the permeability coefficient are greater in the vertical direction than in the horizontal direction, implying a large pore throat has a greater effect on water migration than that of multiple small pore throats.

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

Wei Tingting,Wu Liang,Yu Feng,Lv Yin,Chen Long,Shi Yulin,Dai Bin 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.

Phosphate Transporter MdPHT1;7 Enhances Phosphorus Accumulation and Improves Low Phosphorus and Drought Tolerance

Sun Tingting,Zhou Beibei,Pei Tingting,Meng Hu,Zhang Junke,Ma Fengwang,Wei Qinping 한국식물학회 2021 Journal of Plant Biology Vol.64 No.5

Phosphorus is an important macronutrient for plant growth and is acquired by plants mainly as phosphate. Phosphate fertilizer is usually used to reduce inorganic phosphate (Pi) deficiency in the soil, improve the low phosphorus and drought tolerance of plants, and promote plant growth. Phosphate transporters (PHTs) play an important role in absorbing phosphorus from the soil. MdPHT1;7 was induced by Pi deficiency and drought in roots in our previous research. In this study, we cloned MdPHT1;7 and showed its heterologous expression can complement a high-affinity Pi transporter gene in the Pi uptake-defective yeast mutant BY4743. MdPHT1;7 is a phosphorus transporter located on the cell membrane. Overexpression of MdPHT1;7 in ‘Orin’ apple and ‘Micro-Tom’ tomato enhanced Pi accumulation, low Pi tolerance and drought tolerance. We hypothesized that MdPHT1;7 can enhance Pi absorption and play an important role in improving plant resistance to low phosphorus and drought stresses.

Tingting Zhu,Tao Ai,Wei Zhang,Tao Li,Xiaoming Li 대한영상의학회 2015 Korean Journal of Radiology Vol.16 No.1

To investigate the changes in water content in the lumbar intervertebral discs by quantitative T2 MR imaging in the morning after bed rest and evening after a diurnal load. Twenty healthy volunteers were separately examined in the morning after bed rest and in the evening after finishing daily work. T2-mapping images were obtained and analyzed. An equally-sized rectangular region of interest (ROI) was manually placed in both, the anterior and the posterior annulus fibrosus (AF), in the outermost 20% of the disc. Three ROIs were placed in the space defined as the nucleus pulposus (NP). Repeated-measures analysis of variance and paired 2-tailed t tests were used for statistical analysis, with p < 0.05 as significantly different. T2 values significantly decreased from morning to evening, in the NP (anterior NP = -13.9 ms; central NP = -17.0 ms; posterior NP = -13.3 ms; all p < 0.001). Meanwhile T2 values significantly increased in the anterior AF (+2.9 ms; p = 0.025) and the posterior AF (+5.9 ms; p < 0.001). T2 values in the posterior AF showed the largest degree of variation among the 5 ROIs, but there was no statistical significance (p = 0.414). Discs with initially low T2 values in the center NP showed a smaller degree of variation in the anterior NP and in the central NP, than in discs with initially high T2 values in the center NP (10.0% vs. 16.1%, p = 0.037; 6.4% vs. 16.1%, p = 0.006, respectively). Segmental quantitative T2 MRI provides valuable insights into physiological aspects of normal discs.

Supplementing Vitamin E to the Ration of Beef Cattle Increased the Utilization Efficiency of Dietary Nitrogen

Wei, Chen,Lin, Shixin,Wu, Jinlong,Zhao, Guangyong,Zhang, Tingting,Zheng, Wensi Asian Australasian Association of Animal Productio 2016 Animal Bioscience Vol.29 No.3

The objectives of the trial were to investigate the effects of supplementing vitamin E (VE) on nutrient digestion, nitrogen (N) retention and plasma parameters of beef cattle in feedlot. Four growing Simmental bulls, fed with a total mixed ration composed of corn silage and concentrate mixture as basal ration, were used as the experimental animals. Four levels of VE product, i.e. 0, 150, 300, 600 mg/head/d (equivalent to 0, 75, 150, 300 IU VE/head/d), were supplemented to the basal ration (VE content 38 IU/kg dry matter) in a $4{\times}4$ Latin square design as experimental treatments I, II, III and IV, respectively. Each experimental period lasted 15 days, of which the first 12 days were for pretreatment and the last 3 days for sampling. The results showed that supplementing VE did not affect the nutrient digestibility (p>0.05) whereas decreased the urinary N excretion (p<0.01), increased the N retention (p<0.05) and tended to increase the microbial N supply estimated based on the total urinary purine derivatives (p = 0.057). Supplementing VE increased the plasma concentrations of VE, glucose and triglycerol (TG) (p<0.05) and tended to increase the plasma concentration of total protein (p = 0.096) whereas did not affect the plasma antioxidant indices and other parameters (p>0.05). It was concluded that supplementing VE up to 300 IU/head/d did not affect the nutrient digestibility whereas supplementing VE at 150 or 300 IU/head/d increased the N retention and the plasma concentrations of VE and TG (p<0.05) of beef cattle.

A Novel AC/DC Converter Based on Stacked Boost Circuit and Dual-Mode LLC Circuit

Tingting Yao,Yueshi Guan,Fang Li,Yijie Wang,Wei Wang,Dianguo Xu 전력전자학회 2019 ICPE(ISPE)논문집 Vol.2019 No.5

In this paper, a AC/DC converter based on stacked Boost circuit and dual-mode LLC circuit is proposed. In the Power Factor Correction (PFC) part, two Boost circuits are stacked to reduce switch voltage stress, also sharing one inductor operating in Boundary Conduction Mode (BCM). In the DC/DC part, a dual-mode LLC circuit is adopted based on two stacked half-bridge structure. The input voltage of LLC resonant tank can double or halve by switching between two operating modes. Hence, the voltage gain of LLC converter can be modified without large operating frequency modulation range. The proposed AC/DC converter can be utilized in widely input voltage variation condition. A 50W prototype is proposed in the laboratory and the experimental results verify the feasibility of the proposed converter.

Epidemiologic characteristics and a prognostic nomogram for patients with vulvar cancer: results from the Surveillance, Epidemiology, and End Results (SEER) program in the United States, 1975 to 2016

Shiyuan Wei,Lu Li,Tingting Yi,Licong Su,Qi Gao,Liangzhi Wu,Zhenbo OuYang 대한부인종양학회 2023 Journal of Gynecologic Oncology Vol.34 No.6

Objective: To elucidate clinical characteristics and build a prognostic nomogram for patients with vulvar cancer. Methods: The study population was drawn from the Surveillance, Epidemiology, and End Results (SEER) database. Patients were randomly assigned to training and validation sets. Cox proportional hazards model and competing risk model were used to identify the prognostic parameters of overall survival (OS) and cancer-specific survival (CSS) to construct a nomogram. The nomogram was assessed by concordance index (C-index), area under the curve (AUC), calibration plot, and decision curve analysis (DCA). Results: A total of 20,716 patients were included in epidemiological analysis, of whom 7,025 patients were selected in survival analysis, including 4,215 and 2,810 in training and validation sets, respectively. The multivariate Cox model showed that the predictors for OS were age, marital status, histopathology, differentiation and tumor node metastasis (TNM) stages, whether to undergo surgery and chemotherapy. However, the predictors for CSS were age, race, differentiation and TNM stages, whether to undergo surgery and radiation. The C-index for OS and CSS in the training set were 0.76 and 0.80. The AUC in the training set for 1-, 3- and 5-year OS and CSS were 0.84, 0.81, 0.80 and 0.88, 0.85, 0.83, respectively, which was similar in the validation set. The calibration curves showed good agreement between prediction and actual observations. DCA revealed that the nomogram had a better discrimination than TNM stages. Conclusions: The nomogram showed accurate prognostic prediction in OS and CSS for vulvar cancer, which could provide guidance to clinical practice.
