Hao-Jie Jiang,Chi Gong,Shuai Jiang 사회혁신기업연구원 2024 혁신기업연구 Vol.9 No.1

COVID-19 팬데믹의 영향으로 중국의 미리 포장된 식사 산업이 빠른 성장 단계에 진입하여 소비자들로부터 점점 더 많은 호감을 얻고 있습니다. 이 연구는 중국 소비자들이 미리 포장된 식사를 구매하는 데 영향을 미치는 요인을 탐색하는 것을 목표로 합니다. 우리는 계획된 행동 이론(TPB)과 소비자 혁신성을 사용하여 구조방정식 모델을 구축했습니다. 이 정량적 연구는 비확률 샘플링 온라인 설문조사를 통해 293개의 유효 데이터 포인트를 수집하고 SPSS 27.0 및 AMOS 26.0을 사용하여 모델 검증을 수행했습니다. 결과는 소비자의 도구적 및 정서적 태도가 구매 의도에 중요하게 긍정적인 영향을 미친다는 것을 보여줍니다. 서술적 규범도 구매 의도에 중요한 긍정적인 영향을 미칩니다, 반면 지시적 규범은 중요한 영향을 보이지 않습니다. 소비자의 자기 통제력과 외부 조건은 모두 구매 의도와 행동에 중요한 긍정적인 영향을 미칩니다. 구매 의도는 구매 행동에 중요한 영향을 미치며 자기 통제력과 외부 조건에서의 매개 효과를 가집니다. 소비자 혁신성은 구매 의도와 행동 사이에서 중요한 조절 역할을 합니다. 제품 디자인과 홍보를 강화하기 위해 소비자들에게 매력을 높이는 것이 필수적입니다. 추가 연구를 위한 제안이 제시됩니다. Owing to the impact of the COVID-19 pandemic, the pre-made food industry in China has entered a rapid growth phase, gaining increasing favor from consumers. This study aims to explore the factors influencing Chinese consumers' purchase of pre-made food. We employed the Theory of Planned Behavior (TPB) and consumer innovativeness to construct a structural equation model. This quantitative study gathered 293 valid data points through non-probability sampling online surveys and employed SPSS 27.0 and AMOS 26.0 for model validation. Results reveal that consumers' instrumental and affective attitudes significantly positively influence purchase intention. Descriptive norms also exert a significant positive impact on purchase intention, while injunctive norms do not show a significant effect. Consumers' self-control and external conditions both have significant positive influences on purchase intention and behavior. Purchase intention significantly affects purchase behavior and mediates effects in self-control and external conditions. Consumer innovativeness plays a significant moderating role between purchase intention and behavior. To enhance product design and promotion, it is imperative to increase attractiveness to consumers. Suggestions for further research are presented.

( Jie Yang ),( Ehsan Mostafapour ),( Amir Aminfar ),( Jie Wang ),( Hao Huang ),( Afsaneh Akhbari ),( C. Ghobadi ),( Guan Gui ) 한국인터넷정보학회 2019 KSII Transactions on Internet and Information Syst Vol.13 No.1

In this paper, we investigate the performance of the diffusion adaptation strategies for parameter estimation in wireless adaptive networks, where the nodes exchange information over noisy and fading wireless channels. This paper shows the differences between the effect of Rayleigh and Rician fading over wireless adaptive networks and proves that the Rician fading is a more practical model in such kinds of networks. Simulation results imply that the effect of Rayleigh fading is more degrading for the estimation process than Rician fading. Also, the simulation results show the performance of adapt then combine (ATC) diffusion algorithm is better than the combine then adapt (CTA) algorithm by merely considering noise in wireless channels. While the performance of CTA prevails ATC over the wireless adaptive network in the presence of noise plus channel fading.

A New CIGWO-Elman Hybrid Model for Power Load Forecasting

Hao Jie,Zhu Changsheng,Guo Xiuting 대한전기학회 2022 Journal of Electrical Engineering & Technology Vol.17 No.2

Time series forecasting is a common task that needs to be implemented in many engineering applications. In this paper, for the power load forecasting problem, we explore the advantages of the grey wolf optimization (GWO) algorithm for Elman network optimization. To avoid model complexity, the structure of the Elman network is simplifi ed to improve its training effi ciency. Then, a chaotic sequence and random cosine function are introduced into the GWO algorithm. In addition, the updating methods of individual positions in the particle swarm optimization (PSO) algorithm and diff erential evolution (DE) algorithm are used as references for improving the GWO algorithm. The new chaotic cosine inertial weights GWO (CIGWO) algorithm is used to optimize the parameters of the Elman network, and the CIGWO-Elman network model is formed. Finally, CIGWO-Elman is applied to the actual load data of a city in eastern China to realize short-term power load prediction. The results show that the proposed model has better predictive accuracy and real-time performance than those of other methods

Microstructure and Abrasive Wear Properties of Fe-Cr-C Hardfacing Alloy Cladding Manufactured by Gas Tungsten Arc Welding (GTAW)

Jie-Hao Chen,Chih-Chun Hsieh,Pei-Shing Hua,Chia-Ming Chang,Chi-Ming Lin,Paxon Ti-Yuan Wu,Weite Wu 대한금속·재료학회 2013 METALS AND MATERIALS International Vol.19 No.1

A series of Fe-Cr-C hardfacing alloys is deposited by gas tungsten arc welding and subjected to abrasive wear testing. Pure Fe with various amounts of CrC (Cr:C=4:1) powders are mixed as the fillers and used to deposit hardfacing alloys on low carbon steel. Depending on the various CrC additions to the alloy fillers,the claddings mainly contain hypoeutectic, near eutectic, or hypereutectic microstructures of austenite γ-Fe phase and (Cr,Fe)7C3 carbides on hardfacing alloys, respectively. When 30% CrC is added to the filler, the finest microstructure is achieved, which corresponds to the γ-Fe+(Cr,Fe)7C3 eutectic structure. With the addition of 35% and 40% CrC to the fillers, the results show that the cladding consists of the massive primary (Cr,Fe)7C3 as the reinforcing phase and interdendritic Fe+(Cr,Fe)7C3 eutectics as the matrix. The (Cr,Fe)7C3 carbide-reinforced claddings have high hardness and excellent wear resistance under abrasive wear test conditions. Concerning the abrasive wear feature observable on the worn surface, the formation and fraction of massive primary (Cr,Fe)7C3 carbides predominates the wear resistance of hardfacing alloys. Abrasive particles result in continuous plastic grooves when the cladding has primary γ-Fe phase in a hypoeutectic structure.

Zhen-Jie Liu,Ming-Hao Jin 대한언어학회 2018 언어학 Vol.26 No.4

Liu, Zhen-Jie & Jin, Ming-Hao. (2018). A study of the content validity of reading comprehension tests in NMET II. The Linguistic Association of Korea Journal, 26(4), 103-124. Based on Bachman and Palmer’s (1996) framework of task characteristics, this paper aims to compare the reading comprehension tests of the 2013-2017 National Matriculation English Test II (NMET II) with the requirements of the New Curriculum Standards and Testing Syllabus, in particular, concerning the content validity of the tests in terms of the characteristics of input and expected responses. The implications of this study are discussed for test designers, teachers, and students. The results show that reading comprehension tests from 2013 to 2017 basically meet the requirements of the New Curriculum Standard and Testing Syllabus and have a high content validity. In terms of the characteristics of input, the length, reading speed, and readability of comprehension passages are appropriate for students; however, the distribution of topics and genres in each year is uneven. In terms of the characteristics of expected responses, the wordings of questions and the design of question items are reasonable. However, the response type is mainly restricted to selected response questions (multiple-choice), and the measure of reading skills coverage is unbalanced.

( Jiong-jie Yu ),( Ju-dong Li ),( Xin-fei Xu ),( Zhen-li Li ),( Jun Han ),( Hao Xing ),( Han Wu ),( Jian-hong Zhong ),( Yi-sheng Huang ),( Ya- Hao Zhou ),( Ting-hao Chen ),( Hong Wang ),( Wei-min Gu ) 대한간학회 2018 춘·추계 학술대회 (KASL) Vol.2018 No.1

Aims: There is a striking sex difference in the incidence of hepatocellular carcinoma (HCC), with a strong predominance for males. However, the impact of sex on the incidence of recurrence after curative resection of HCC remains controversial. Herein, we assess sex differences in the risks of recurrence and mortality for patients undergone curative resection of HCC. Methods: Data from 1,435 HCC patients undergone curative resection (1,228 males and 207 females) between 2004 and 2014 at five institutions in China were retrospectively analyzed. Patients’ baseline characteristics, operative variables, and rates of early recurrence (≤ 2 years after resection), late recurrence (> 2 years) and cancer-specific mortality (CSM) were evaluated and compared. Multivariable competing-risks regression analyses were performed to identify predictors associated with CSM, early and late recurrence. Results: The early recurrence rates between males and females were similar (43.3% vs. 42.0%, P=0.728), but the late recurrence and CSM rates in males were higher when compared to females (17.2% vs. 11.2%, P=0.044; 42.8% vs. 34.3%, P=0.022). Multivariable competing-risks regression analyses revealed no sex difference in early recurrence; however, males had significantly higher late recurrence rate [hazard ratio (HR), 1.752; 95% CI, 1.145-2.682; P=0.010] and CSM rate (HR, 1.307; 95% CI, 1.015-1.683; P=0.038) than females. Conclusions: Males had significantly higher late recurrence and CSM rates after curative resection of HCC than females. This suggests postoperative surveillance for HCC recurrence be varied by sex, especially for patients without recurrence at 2 years after resection.

New Therapeutic Schedule for Prostatic Cancer-3 Cells with ET-1 RNAi and Endostar

Zhang, Hao-Jie,Qian, Wei-Qing,Chen, Ran,Sun, Zhong-Quan,Song, Jian-Da,Sheng, Lu Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.23

Background: Endothelin-1 and Endostar are both significant for the progression, proliferation, metastasis and invasion of cancer. In this paper, we studied the effect of ET-1 RNAi and Endostar in PC-3 prostatic cancer cells. Materials and Methods: The lentiviral vector was used in the establishment of ET-1 knockdown PC-3 cells. Progression and apoptosis were assessed by CKK-8 and flow cytometry, respectively. Transwell assay was used to estimate invasion and signaling pathways were studied by Western blotting. Results: ET-1 mRNA and protein in ET-1 knockdown PC-3 cells were reduced to 26.4% and 22.4% compared with control group, respectively. ET-1 RNAi and Endostar both were effective for the suppression of progression and invasion of PC-3 cells. From Western blotting results, the effects of ET-1 regulation and Endostar on PC-3 cells were at least related to some signaling pathways involving PI3K/Akt/Caspase-3, Erk1/2/Bcl-2/Caspase-3 and MMPs (MMP-2 and MMP-9). Furthermore, combined treatment of ET-1RNAi and Endostar was found to be more effective than single treatment. Conclusions: Both ET-1 RNAi and Endostar can inhibit the progression and invasion of PC-3 cells, but combined treatment might be a better therapeutic schedule.

CNN-based Skip-Gram Method for Improving Classification Accuracy of Chinese Text

( Wenhua Xu ),( Hao Huang ),( Jie Zhang ),( Hao Gu ),( Jie Yang ),( Guan Gui ) 한국인터넷정보학회 2019 KSII Transactions on Internet and Information Syst Vol.13 No.12

Text classification is one of the fundamental techniques in natural language processing. Numerous studies are based on text classification, such as news subject classification, question answering system classification, and movie review classification. Traditional text classification methods are used to extract features and then classify them. However, traditional methods are too complex to operate, and their accuracy is not sufficiently high. Recently, convolutional neural network (CNN) based one-hot method has been proposed in text classification to solve this problem. In this paper, we propose an improved method using CNN based skip-gram method for Chinese text classification and it conducts in Sogou news corpus. Experimental results indicate that CNN with the skip-gram model performs more efficiently than CNN-based one-hot method.

Risk Factors, Patterns, and Outcomes of Late Recurrence after Liver Resection for Patients with Hepatocellular Carcinoma (Analysis of a Multicenter Cohort over 15 Years)

( Xin-fei Xu ),( Jiong-jie Yu ),( Ju-dong Li ),( Hao Xing ),( Jun Han ),( Zhen-li Li ),( Han Wu ),( Han Zhang ),( Jian-hong Zhong ),( Yi- Sheng Huang ),( Ya-hao Zhou ),( Ting-hao Chen ),( Hong Wang ) 대한간학회 2018 춘·추계 학술대회 (KASL) Vol.2018 No.1

Aims: Late recurrence (> 2 years) after liver resection of hepatocellular carcinoma (HCC) is usually considered as multi-centric tumors or de novo cancer formation. We aimed to investigate risk factors, patterns and outcomes of late recurrence after HCC resection. Methods: From a multicenter database from 2001 to 2015, 734 patients who were alive and recurrence-free at 2 years after curative resection of initial HCC were enrolled into this retrospective study. Univariate and multivariate Cox-regression analysis were used to identify independent risk factors of late recurrence. Patterns, treatments and outcomes of late recurrence were investigated and analyzed. Results: During a median follow-up of 78.0 months after surgery, 303 patients (41.3%) developed late recurrence. Multivariate analysis revealed that cirrhosis, macroscopic vascular invasion, satellites, and tumor size > 5cm were independent risk factors of late recurrence. Among them, 273 (90.1%) were sole intrahepatic recurrence, 30 (9.9%) were concurrent intrahepatic and extrahepatic recurrence, and none of them was sole extrahepatic recurrence; 165 (54.4%) patients received curative treatments for recurrent HCC, including re-resection, transplantation and local ablation. Multivariate analysis showed regular postoperative surveillance and receiving curative treatments were two independent protective factors of prolonging survival for those patients with late recurrence. Conclusions: Late recurrence is correlated with cirrhosis and certain tumor-related characteristics of initial HCC. The patterns of late recurrence suggest that postoperative surveillance after 2 years of surgery could be adjusted and more targeted. Regular postoperative surveillance improves the probability to receive curative treatments again, yielding to better outcomes for patients with late recurrence.
