With the wide application of intelligent household appliances, the optimization of electricity behavior has become an important component of home-based intelligent electricity. In this study, a multi-objective optimization model in an intelligent electricity environment is proposed based on economy and comfort. Firstly, the domestic consumer's load characteristics are analyzed, and the operating constraints of interruptible and transferable electrical appliances are defined. Then, constraints such as household electrical load, electricity habits, the correlation minimization electricity expenditure model of household appliances, and the comfort model of electricity use are integrated into multi-objective optimization. Finally, a continuous search multi-objective particle swarm algorithm is proposed to solve the optimization problem. The analysis of the corresponding example shows that the multi-objective optimization model can effectively reduce electricity costs and improve electricity use comfort.

1930年代国共两党政治博弈中的丁玲形象研究

曲向楠 ( Qu Xiang Nan ) 한국중국어문학회 2022 中國文學 Vol.111 No.-

1927년부터 1936년까지 연속간행물에 실린 딩링 관련 언급은 주로 딩링 실종사건에 관한 것이며 이 사건을 계기로 국공양당의 여론 대결이 벌어졌다. 이번 여론 대결은 국민당의 공신력 훼손과 좌익 문인에 대한 비밀처형, 언론 봉쇄 등 ‘전과'로 인해 초반부터 대결에서 불리한 위치에 처하였다. 또한 국민당은 딩링의 스캔들을 조작하는데 주력했지만 공산당은 딩링의 작품이나 생애에 대한 전문적인 평가 글을 발표한 것을 통하여 딩링의 혁명적 여걸 이미지를 구축하였다. 딩링은 작품 활동 초기부터 자신의 작품과 상관없이 과대평가되거나 과소평가되었으며, 본고는 국공양당의 경합 속에서 형성된 딩링 언론에 나타난 딩링 이미지 구축을 통하여 이것의 이유를 고찰하고자 한다. The commentaries about Ding Ling published in newspapers and magazines from 1927 to 1936 mainly revolved around the disappearance of Ding Ling, and the Kuomintang and the Communist Party launched a confrontation in the field of public opinion by virtue of Ding Ling’s disappearance. In this confrontation, due to the damage to the Kuomintang’s credibility, as well as its record of arresting left-wing literati, carrying out secret executions, and blocking of speech, etc., they were at a disadvantage from the very beginning of the duel. Moreover, the Kuomintang used the main public opinion offensive to create Ding Ling's affairs. When Ding Ling's disappearance was first reported, there were scandals such as Ding Ling living together with Ma Shaowu and being in love with many literati.

Zhaoyang Qu,Wanxin Wang,Nan Qu,Yuqing Liu,Hongbo Lv,Kewei Hu,Jianyou Yu,Manyang Gao,Jiajun Song 대한전기학회 2019 Journal of Electrical Engineering & Technology Vol.14 No.4

In order to improve the accuracy of forecasts of the electricity sales of power sales companies, a depth forecast model of electricity sales based on the characteristics of the power market is proposed. First, based on survival analysis, the calculation method of the user churn rate in the electricity market is given, and the number of users at a certain moment in the future is predicted. Then, users’ electricity consumption that calculated by the deep belief network and the predicted quantity of users are combined to design a forecast model of electricity sales. Finally, the model is solved utilizing the weighting algorithm of adaptive inertia. The analysis of the example shows that the proposed method achieves a signifi cant improvement in the accuracy of power sales forecasting.

Zhao-Yang Qu,Yong-Wen Wang,Chong Wang,Nan Qu,Jia Yan 보안공학연구지원센터 2016 International Journal of Database Theory and Appli Vol.9 No.3

The data cleaning of electrical power big data can improve the correctness, the completeness, the consistency and the reliability of the data. Aiming at the difficulties of the extracting of the unified anomaly detection pattern and the low accuracy and continuity of the anomaly data correction in the process of the electrical power big data cleaning, the data cleaning model of the electrical power big data based on Spark is proposed. Firstly, the normal clusters and the corresponding boundary samples are obtained by the improved CURE clustering algorithm. Then, the anomaly data identification algorithm based on boundary samples is designed. Finally, the anomaly data modification is realized by using exponential weighting moving mean value. The high efficiency and accuracy is proved by the experiment of the data cleaning of the wind power generation monitoring data from the wind power station.

Gallbladder Cancer: a Subtype of Biliary Tract Cancer Which is a Current Challenge in China

Qu, Kai,Liu, Si-Nan,Chang, Hu-Lin,Liu, Chang,Xu, Xin-Sen,Wang, Rui-Tao,Zhou, Lei,Tian, Feng,Wei, Ji-Chao,Tai, Ming-Hui,Meng, Fan-Di Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.4

Biliary tract cancers, broadly described as malignancies that arise from the biliary tract epithelia, are usually divided into two major clinical phenotypes: cholangiocarcinoma and gallbladder cancer, differing in etiopathogenesis, risk factors, and perhaps molecular and genetic signatures. Atypical symptoms and lack of tumor biomarkers make it difficult to diagnose in early stages. At the time of presentation, few patients are candidates for potentially curative surgical resection. We here assessed and compared features of a total of 150 cases divided into extra- and intrahepatic cholangiocarcinomas and gallbladder cancers (GBC). Althought there were no significant differences in serum tumour marker levels, GBC patients had the poorest prognosis. Furthermore, gallbladder cancer respond poorly to chemotherapy or radiation therapy and approximately half of untreated patients died within 10 months. Therefore, treatment for patients with gallbladder cancer is still in challenge. Outcomes and survival of these patients had improved little over the past three decades - a period in which new successful treatments have greatly contributed to the prolonged patient survival for many other cancers.

Prognosis and Management for Gallbladder Cancer with Hepatic Invasion: Long-term Results of 139 Patients from a Single Center in China

Objective: To improve the diagnosis of primary gallbladder carcinoma (GBC) with/without hepatic metastases by analyzing our experience of different GBC treatment in our patients. Methods: A retrospective study was carried out to analyze the clinical data of the 139 patients with GBC who underwent hepatic resection in our unit from January 2003 to December 2007. Patients were divided into two groups according to whether they demonstrated hepatic invasion. Tumor presentation, surgical modes, and prognosis of each patient were retrospectively reviewed. Kaplan-Meier curves and log-rank tests were employed to compare the survival rates of those patients undergoing different surgical procedures. Results: Of the 139 patients, 46 were men and 93 were women with the male to female ratio of 1:2.0. Their ages were ranged from 35 to 86 years with a mean age of $62.8{\pm}10.4$ years. There were 73 patients complicated with hepatic invasion (group A), and no hepatic invasion occurred in the other 66 patients (group B). Compared with the group B, the patients with hepatic invasion suffered lower differentiation of tumor (p=0.000), more advanced Nevin staging (p=0.008) and poorer prognosis (p=0.013). Radical resection were more frequently performed in group B (75.76%) than in group A (45.20%) with better outcomes (p=0.000). Conclusion: GBC patients complicated with hepatic invasion had poorer prognosis than those without invasion in long-term follow-ups. Radical resection might result in a satisfied prognosis in patients without hepatic invasion, but appears less favorable than palliative resection in those who were complicated with hepatic invasion.

The activation of Wnt signaling facilitates autophagy by modulating GSK-3β-AMPK axis in atherosclerosis

Qu Shifang,Zhang Kuanxin,Jin Nan,Li Han,Nie Bin 대한독성 유전단백체 학회 2023 Molecular & cellular toxicology Vol.19 No.4

Background Endothelial dysfunction induced by oxidized low-density lipoprotein (ox LDL) is implicated in the pathogenesis of atherosclerosis (AS). Activated autophagy was reported to improve endothelial functions and alleviate AS development. AMPK is a key protein in the regulation of autophagy, which can be modulated by Wnt signaling pathway. Objective Our study was designed to explore whether the canonical Wnt activator Wnt3a promotes autophagy in AS through in vitro and in vivo assays. Results Human umbilical vein endothelial cells (HUVECs) were fi rst treated with ox LDL at 50 μg/mL for 24 h and then transfected with Wnt3a-overexpressed plasmid pcDNA3.1/Wnt3a. At 48 h after transfection, HUVECs were treated with 100 μM 3-MA. To investigate the eff ects of GSK-3β inhibition on the activation of AMPK, HUVECs were treated with 10 μM TWS119. Cell viability was detected via Trypan blue staining. Wnt3a expression, autophagy markers, GSK-3β inhibition and AMPK activation were examined by western blotting. To induce animal model of AS, male apolipoprotein E defi cient (ApoE −/− ) mice were fed with high-fat diet. pcDNA3.1/Wnt3a was injected into ApoE −/− mice after high-fat diet induction. Oil Red O staining was performed to examine lipid and plaque deposition in atherosclerotic lesions. In this study, ox LDL treatment decreased HUVEC viability and downregulated Wnt3a expression. Wnt3a overexpression promoted autophagy, induced GSK-3β phosphorylation at Ser9, and AMPK phosphorylation at Thr172 in ox-LDL-stimulated HUVECs. Overexpressing Wnt3a ameliorated lipid accumulation in aortic plaque of ApoE −/− mice. Furthermore, Wnt3a overexpression also activated autophagy, and induced GSK-3β and AMPK phosphorylation in ApoE −/− mice. Conclusion Wnt3a activates AMPK through inhibiting GSK-3β, thereby facilitating autophagy in AS.

Nan An,Il-Sang Go,Min Qu 한국인터넷전자상거래학회 2019 인터넷전자상거래연구 Vol.19 No.2

Under the context that SNS is turning to a commerce tool from a communicate tool, this study investigates the antecedents of value and attitude toward SINA Weibo advertising, and examines the role of social media advertising positive and negative attributes as determinants of perceived advertising value and user’s positive attitude toward advertising. Moreover, this study explored the relationships between perceived advertising value, user’s positive attitude toward advertising and users’ ads adoption. A conceptual model and hypotheses are tested with a sample of 304 SINA Weibo users, and conducted AMOS 22.0 analysis. Overall, the findings provided support for the model of the study. First, more informativeness, more entertainment, and more credibility to create higher user’s advertising adoption in the SINA Weibo environment. Second, user-defined customization directly affects the user`s attitude without the indirect impact of perceived value. Third, irritation is not important attributes affecting user’s perceived ad value and positive attitude toward SINA Weibo advertising. Fourth, privacy concerns also directly affects users` attitudes toward SINA Weibo advertising. The study adds to and expands our knowledge of the antecedents and consequences of SINA Weibo users behaviour regarding advertising and therefore act as a valuable base of social media advertising practitioners.
