Yabo He,Wang Hongtao,Yang Lin,Qin Wei4 보안공학연구지원센터 2016 International Journal of Smart Home Vol.10 No.2

With the increase of construction investment and urbanization, building waste output in our country is huge. This paper first constructs a set based on the construction area and per unit area of garbage generated quantity of urban building waste estimation method, then using grey system theory prediction and analysis of the next four years of building waste output. By the introduction of metabolic thought, the grey metabolic GM (1,1) forecast model was constructed, overcoming the shortages of conventional GM (1, 1) model. Prediction results show that the model is higher than the conventional GM (1,1) model prediction accuracy, which is suitable for the prediction of the short term of building waste in our country and for the treatment and reuse of building waste to provide certain reference.

The Manifestations, Causes, Impacts and Across Paths of Pan-Securitization

Zong Wei(Wei Zong),He Haiyang(Haiyang He) 아시아사회과학학회 2023 Jornal of Asia Social Science Vol.10 No.2

In recent years, with the decline of globalization, the rise of nationalism in the US and Western countries has become more prominent. They have adopted conservative policies under the pretext of national security, leading to the proliferation of pan-securitization. Facing various and complex security challenges, countries have attached more importance to national security. Anyway, based on the Copenhagen School’s theory of securitization, the process of securitization can result in pansecuritization, which manifests in three aspects: the worship of securitization at the initiation stage; the excessive expansion of issues at the development stage; and the difficulty of de-securitization at the post-securitization stage. On the one hand, pansecuritization can cause problems such as security capital overdraft, radical change cultivation, lack of common security perception and human rights protection impairment within a country. On the other hand, it can also cause problems such as production efficiency reduction and security dilemma induction at the international level. The causes of pan-securitization are complex, but mainly stem from the interconnection of security threats, the monopoly of speech power by agents, the centralist political form and the endogenous defects of the Copenhagen School’s securitization theory. Today, guided by the overall national security concept, national security has received unprecedented attention. In view of the pan-securitization trap that the US and Western countries have fallen into, we should take measures from three aspects: security democratization, security legalization and de-worship of securitization to avoid repeating their mistakes. Only in this way can we enhance the effectiveness of issue securitization and improve the implementation efficiency of security policies.

Wei He,Gerhard Litscher,Dominik Wedig,Ingrid Gaischek 사단법인약침학회 2012 Journal of Acupuncture & Meridian Studies Vol.5 No.6

Violet laser acupuncture was recently described by our research group. Neurochemical studies of acupuncture analgesia revealed that 2- and 100-Hz peripheral stimulation induce differential peptide release from preproenkephalin and preprodynorphin via different neural pathways. The goal of the fifth part of this series was to perform a pilot investigation on the effects of 2- and 100-Hz violet laser acupuncture on heart rate (HR) and its variability (HRV) in 13 healthy volunteers (mean age ± standard deviation: 23.9 ± 1.7 years) using a new non-invasive method. We found a significant difference in mean HR before, during, and after 2- or 100-Hz violet laser acupuncture, and there was a significant difference of the low frequency/ high frequency ratio before, during, and after 2- or 100-Hz violet laser acupuncture. However, we did not observe a significant difference in total HRV before, during, or after treatment. Further studies should be carried out to compare the effects of different violet laser acupuncture frequencies.

Three new compounds (1-3), including a neolignan, a triterpenoid, and a diterpenoid, together with twenty known compounds (4-23), were isolated from the aerial parts of Isodon coetsa. Their structures and relative configurations were elucidated on the basis of spectroscopic data. Compounds 1, 3, 5-9, 11-13, 16-17, and 19-23 were evaluated for their cytotoxicity against HT-29, BEL-7402, and SK-OV-3 human tumor cell lines. Compound 7 showed significant inhibitory effects on all three types of cells, with IC50 values of 2.52, 3.06, 2.14 μM, respectively.

Cubic-Structured <tex> $\hbox{HfO}_{2}$</tex> With Optimized Doping of Lanthanum for Higher Dielectric Constant

Wei He,Chan, D.S.H.,Lu Zhang,Byung Jin Cho IEEE 2009 IEEE electron device letters Vol.30 No.6

<P>It is demonstrated that HfO<SUB>2</SUB> films can have much higher dielectric-constant values than the usual reported value of 20-24 by optimized incorporation of lanthanum element and crystallization to cubic structure. When HfO<SUB>2</SUB> with 8% La is crystallized into cubic structure, the film exhibits the kappa value of ~38 which is the highest among ever reported HfO<SUB>2</SUB> -based high-kappa dielectrics. The increased kappa value of HfO<SUB>2</SUB> with 8% La enables the leakage current to be reduced more than one order of magnitude lower, compared to amorphous-phase HfO<SUB>2</SUB> under the same electric field. The dependence of film thickness and annealing temperature on the cubic crystallization is also reported.</P>

Acoustic Model Fusion Method of British and American Compatible Mode

Wei He 보안공학연구지원센터 2016 International Journal of Future Generation Communi Vol.9 No.12

The British and American English are the most common target accents. British and American English have different phonetic symbol and pronunciation system. These two accents have many learners. And some learners have mixed phenomenon of British and American accent. Based on the mixed phenomenon British and American English accent for English learners, this paper put forwarder a model of American and British accent fusion method, improve the quality of the pronunciation evaluation performance system, and realize the embedded compressed acoustic model. This method divide acoustic model into alternative model, fusion model and encourage model by replace probability. The alternative model could be removed, and isolated model could be reserved. The fusion model could be merged based on model interpolation and model clip. Pronunciation quality evaluation results showed that the correlation of speaker level increased by 14.1%, compared with single accent model and in fusion model,; fusion model was similar to the performance of the hybrid model, the figure of gaussian component compressed by 10.7%.

중국 대학생의 성취동기, 자기주도적 학습능력과 교수의 수업의 질 인식의 관계

He, Wei,전춘련 학습자중심교과교육학회 2020 학습자중심교과교육연구 Vol.20 No.16

This study aims to look into how Chinese university students tend to perceive the class quality of Chinese professors along with how the perceptions of university students on class quality differ according to their achievement motivations and self-directed learning abilities and how their perceptions of class quality affect their perceptions on their own university grades and university satisfaction. To this end, 275 undergraduate students from three universities in Zhejiang Province were studied from May 1 to May 18, 2019. Research results showed that no differences were shown among perceptions on the class quality of professors, achievement motivations, and self-directed learning abilities between genders or grades but satisfaction was higher for those with higher grades so students with excelling grades perceived class quality to be good. Therefore, this implies that improvement efforts such as class attitude, class preparation, and class methods are important but that they are meaningless if such efforts do not lead to class satisfaction and more than anything else, professors must focus on providing class services that students can be satisfied with for the enhancement of class quality. 본 연구는 중국 교수의 수업의 질에 대하여 중국 대학생은 어떻게 인식하고 있는지 그 경향성을 파악하고, 대학생들의 성취동기, 자기 주도적 학습능력에 따라 그들의 수업의 질 인식이 다른지, 그리고 수업의 질 인식은 자신들의 대학성적 인식과 대학 만족에 영향을 주는지를 밝히는 데에 목적이 있다. 이를 위해 2019년 5월 1일부터 5월 18일까지 중국 절강성에 소재하는 3개 대학의 학부생 275명을 대상으로 연구를 진행하였다. 연구결과, 교수의 수업의 질, 성취동기, 자기 주도적 학습능력에 대한 인식은 남녀 간, 학년 간은 차이가 없었으나, 성적이 좋을수록 만족도가 높아 성적이 우수한 학생일수록 수업의 질을 좋게 인식하였다. 따라서 대학은 수업 태도, 수업 준비, 수업 방법 등의 개선 노력도 중요하지만 결국 이러한 노력은 수업 만족으로 이어지지 않으면 의미가 없다는 것을 시사함으로 교수는 무엇보다 수업의 질 향상을 위한 학생들이 만족하는 수업 서비스를 제공하는 데에 초점을 맞추어야 한다.

Zhizhu Decoction Promotes Gastric Emptying and Protects the Gastric Mucosa

Wei He,Yi Zhang,Xinrui Wang,Lingling Guo,Lifeng Han,Erwei Liu,Tao Wang 한국식품영양과학회 2013 Journal of medicinal food Vol.16 No.4

The aim of this study was to evaluate the effects of the Zhizhu decoction on gastric emptying and gastric mucosal protection. The Zhizhu decoction is composed of Aurantii fructus and Atractylodes macrocephala Rhizoma. Results showed that oral administration of the Zhizhu decoction accelerated gastric emptying in mouse and protected gastric mucosa from ethanol-induced ulcers in rat. Our investigations demonstrated that the Zhizhu decoction accelerated gastric emptying, at least in part, by activating the muscarinic and 5-HT3 receptors. The gastroprotective effect is involved in its antioxidant effects and increased vascular endothelial growth factor expression.

An Improved Integrative Transformation System for Pichia pastoris with DNA-polyethylenimine-dextran Sulfate Nanoparticles

Wei Xue,Hang Wang,Zuodi Pei,Wei Zhao,Yong-Sheng Tian,Ri-He Peng,Quan-Hong Yao 한국생물공학회 2013 Biotechnology and Bioprocess Engineering Vol.18 No.3

Pichia pastoris is a suitable host for selecting mutant enzymes, since it can secret many gene products to the medium. However, poor transformation efficiency is often encountered. This makes it difficult to obtain a large number of transformants necessary to thoroughly cover a large library. We report here that pre-coating DNA with polyethyleneimine and dextran sulfate increased gene integration significantly in Pichia electroporation. This improvement on integrative efficiency has been proved in different voltage, resistance, cell phase, and DNA concentrations. The condensed DNA nanoparticles make Pichia available as a host for screening large libraries of random mutants.
