Research of Chinese Auspicious Elements in Tableware Design

Yue-Xin Huang,BumKyu Kang 한국콘텐츠학회(IJOC) 2013 International Journal of Contents Vol.9 No.4

Chinese auspicious element is a kind of art which is used to express yearning of a happy life. It is one of the great treasures of China, with not only emotional value of the people but also an aesthetic value. Chinese auspicious element derives from the aspiration of luck, enthusiasm of life and conciseness of eliminating malicious. It is of great cultural connotation and widely used in interior design, graphic design, fashion design and such. There are many research papers on application methodology of auspicious elements; however, there are very limited research papers on three-dimension product, let alone application in tableware. This paper focuses on illustration of Chinese representative auspicious element “auspicious fish” in tableware design. The research of its application of auspicious element’s styling characteristics is of important significance in auspicious element spread and tableware design. This dissertation aims to provide referential design methodology and experience for later researches on related topic.

Vegetable Oil Intake and Breast Cancer Risk: a Meta-analysis

Xin, Yue,Li, Xiao-Yu,Sun, Shi-Ran,Wang, Li-Xia,Huang, Tao Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.12

Background: Total fat intake may be associated with increased risk of breast cancer, and fish oil has been suggested as a protection factor to breast cancer. But the effect of vegetable oils is inconclusive. We aimed to investigate the association with high vegetable oils consumption and breast cancer risk, and evaluated their dose-response relationship. Design: We systematically searched the MEDLINE, EMBASE, Cochrane databases, and CNKI updated to December 2014, and identified all observational studies providing quantitative estimates between breast cancer risk and different vegetable oils consumption. Fixed or random effect models were used to estimate summary odds ratios for the highest vs. lowest intake, and dose-response relationship was assessed by restricted cubic spline model and generalized least-squares trend (GLST) model. Results: Five prospective cohort studies and 11 retrospective case-control studies, involving 11,161 breast cancer events from more than 150,000 females, met the inclusion criteria. Compared with the lowest vegetable oils consumption, higher intake didn't increased the risk of breast cancer with pooled OR of 0.88 (95% CIs:0.77-1.01), and the result from dose-response analyses didn't show a significant positive or negative trend on the breast cancer risk for each 10g vegetable oil/day increment (OR=0.98, 95% CIs: 0.95-1.01). In the subgroup analyses, the oils might impact on females with different strata of BMI. Higher olive oil intake showed a protective effect against breast cancer with OR of 0.74 (95% CIs: 0.60-0.92), which was not significant among the three cohort studies. Conclusions: This meta-analyses suggested that higher intake of vegetable oils is not associated with the higher risk of breast cancer. Olive oil might be a protective factor for the cancer occurrence among case-control studies and from the whole. Recall bias and imbalance in study location and vegetable oils subtypes shouldn't be ignored. More prospective cohort studies are required to confirm the interaction of the impact of vegetable oils on different population and various cancer characteristic, and further investigate the relationship between different subtype oils and breast cancer.

Huang, Xin,Liu, Yan,Zhang, Yong,Li, Shuai-Ping,Yue, Hao,Chen, Chang-Bao,Liu, Shu-Ying The Korean Society of Ginseng 2019 Journal of Ginseng Research Vol.43 No.1

Background: The structural conversions in ginsenosides induced by steaming or heating or acidic condition could improve red ginseng bioactivities significantly. In this paper, the chemical transformations of red American ginseng from fresh Panax quinquefolium L. under steaming were investigated, and the possible mechanisms were discussed. Methods: A method with reversed-phase high-performance liquid chromatography coupled with linear ion trap mass spectrometry ($HPLC-MS^n$)-equipped electrospray ionization ion source was developed for structural analysis and quantitation of ginsenosides in dried and red American ginseng. Results: In total, 59 ginsenosides of protopanaxadiol, protopanaxatriol, oleanane, and ocotillol types were identified in American ginseng before and after steaming process by matching the molecular weight and/or comparing $MS^n$ fragmentation with that of standards and/or known published compounds, and some of them were determined to be disappeared or newly generated under different steaming time and temperature. The specific fragments of each aglycone-type ginsenosides were determined as well as aglycone hydrated and dehydrated ones. The mechanisms were deduced as hydrolysis, hydration, dehydration, and isomerization of neutral and acidic ginsenosides. Furthermore, the relative peak areas of detected compounds were calculated based on peak areas ratio. Conclusion: The multicomponent assessment of American ginseng was conducted by $HPLC-MS^n$. The result is expected to provide possibility for holistic evaluation of the processing procedures of red American ginseng and a scientific basis for the usage of American ginseng in prescription.

Yue-Xin Liu,Shi-Man Du,Jie Cao,Wen-sheng Huang,Xiao-Ru Zhang,Bao-Ping Qi,Sheng-Hui Zhang 대한화학회 2020 Bulletin of the Korean Chemical Society Vol.41 No.3

N-doped porous biochar (NPB) with large conjugated systems could not only be used as enrichment carriers but also be in favor of electron transport in the electrochemical detection. The NPB-modified electrode was fabricated for the simultaneous detection of catechol (CA) and hydroquinone (HQ) to enhance the signal-to-noise ratio and further improve the sensitivity. A detection limit as low as 37 and 47?nM was achieved for CA and HQ, respectively. The proposed strategy with the merits of high sensitivity, selectivity, and reproducibility exhibited a great potential for the detection.

Xuewu Huang,Bei Li,Xin Song,Ling Wang,Yue Shi,Mingjun Hu,Jiefeng Gao,Huaiguo Xue 한국공업화학회 2019 Journal of Industrial and Engineering Chemistry Vol.70 No.-

Aflexible, stretchable and electrically conductive nanofiber composite with superhydrophobicity wasfabricated by ultrasonication induced carbon nanotubes (CNTs) decoration onto the polymer nanofiber,followed by methyltrichlorosilane (MTS) modification. The introduction of CNTs and polysiloxanederived from MTS improved the superhydrophobicity, conductivity, thermal stability and mechanicalproperties of the nanofibrous membrane. The superhydrophobicity and electrical conductivity could bemaintained during the cyclic stretching. The nanofiber composite membrane could be utilized toseparate the oil from the oil/water mixture regardless of pH of water, exhibiting a largeflux, highefficiency and good recyclability.

Risk of venous thromboembolism in Chinese pregnant women: Hong Kong venous thromboembolism study

Duo Huang,Emmanuel Wong,Ming-Liang Zuo,Pak-Hei Chan,Wen-Sheng Yue,Hou-Xiang Hu,Ling Chen,Li-Xue Yin,Xin-Wu Cui,Ming-Xiang Wu,Xi Su,Chung-Wah Siu,Jo-Jo Hai 대한혈액학회 2019 Blood Research Vol.54 No.3

BackgroundPrevious Caucasian studies have described venous thromboembolism in pregnancy; however, little is known about its incidence during pregnancy and early postpartum peri-od in the Chinese population. We investigated the risk of venous thromboembolism in a “real-world” cohort of pregnant Chinese women with no prior history of venous thromboembolism.MethodsIn this observational study, 15,325 pregnancies were identified in 14,162 Chinese women at Queen Mary Hospital, Hong Kong between January 2004 and September 2016. Demographic data, obstetric information, and laboratory and imaging data were retrieved and reviewed.ResultsThe mean age at pregnancy was 32.4±5.3 years, and the median age was 33 years (interquartile range, 29‒36 yr). Pre-existing or newly diagnosed diabetes mellitus was present in 627 women (4.1%); 359 (0.7%) women had pre-existing or newly detected hypertension. There was a small number of women with pre-existing heart disease and/or rheumatic conditions. Most deliveries (86.0%) were normal vaginal; the remaining were Cesarean section 2,146 (14.0%). The incidence of venous thromboembolism was 0.4 per 1,000 pregnancies, of which 83.3% were deep vein thrombosis and 16.7% were pul-monary embolism. In contrast to previous studies, 66.7% of venous thrombosis occurred in the first trimester.ConclusionChinese women had a substantially lower risk of venous thromboembolism during preg-nancy and the postpartum period compared to that of Caucasians. The occurrence of pregnancy-related venous thromboembolism was largely confined to the early preg-nancy period, probably related to the adoption of thromboprophylaxis, a lower rate of Cesarean section, and early mobilization.

Spatiotemporal attention aided graph convolution networks for dynamic spectrum prediction

Li Yue,Shen Bin,Wang Xin,Huang Xiaoge 한국통신학회 2024 ICT Express Vol.10 No.4

To solve the spectrum scarcity problem, dynamic spectrum access (DSA) technology has emerged as a promising solution. Effectively implementing DSA demands accurate and efficient spectrum prediction. However, complex spatiotemporal correlation and heterogeneity in spectrum observations usually make spectral prediction arduous and even ambiguous. In this letter, we propose a spectrum prediction method based on an attention-aided graph convolutional neural network (AttGCN) to capture features in both spatial and temporal dimensions. By leveraging the attention mechanism, the AttGCN adapts its attention weights at different time steps and spatial positions, thus enabling itself to seize changes in spatiotemporal correlations dynamically. Simulation results show that the proposed spectrum prediction method performs better than baseline algorithms in long-term forecasting tasks.

Robust Optimization Dispatch Method for Distribution Network Considering Four-Quadrant Power Output of Energy Storage Devices

Li Yue,Xiao Xiao-Bing,He Xiao-Meng,Huang Bo-Yang,Fang Yang,He Xin-Yi 대한전기학회 2024 Journal of Electrical Engineering & Technology Vol.19 No.2

This paper describes a technique for improving distribution network dispatch by using the four-quadrant power output of distributed energy storage systems to address voltage deviation and grid loss problems resulting from the large integration of distributed generation into the distribution network. The approach creates an optimization dispatch model for an active distribution network. The objective function aims to minimize power purchase costs, network loss costs, and voltage deviation penalties. In addition, the method employs an interval robust optimization technique to handle uncertainties related to solar turbine output and load demand. To solve the optimal power fow problem for AC in the distribution network, this paper implements the second-order cone relaxation technique to convert it into a solvable second-order cone programming problem. Moreover, the Big-M method is used to handle the nonlinear terms in the objective function. Finally, simulation experiments are conducted on the IEEE33 node system to verify the efectiveness and superiority of the proposed method. The simulation results indicate that the system's operating cost can be signifcantly reduced. Additionally, it has a positive impact on reducing voltage deviation and system loss, ultimately improving the operation of the distribution network system.
