Objective To measure residents’ abilities to acquire, analyze and evaluate information on media in southwestern China and to explore its predictive factors. Methods The convenience sampling method was used. A web-based questionnaire survey was conducted among 774 residents during the Spring Festival in 2020. Results Young, highly educated, unmarried, high-income, and urban residents preferred to seek and acquire information about COVID-19 epidemic through new media channels. Elderly residents tended to obtain information through television. Residents with low educational background and rural residents were more dependent on community information media. To analyze residents’ abilities in the judgement of 15 statements about COVID-19, residents with a master’s degree or above (OR = 2.755, [95% CI 1.160-6.542]) had better media literacy in identifying false health information released on social networking. Rural residents (OR = 0.609, [95% CI 0.433-0.855]) had lower media literacy. The total score decreased by 2.6% for every one-year increase of age. Conclusion Residents’ abilities to acquire, analyze and evaluate information were affected by their demographic characteristics in southwestern China. The authorities and local communities should develop different approaches of information dissemination, with the help of traditional and new media. It is important to improve the level of residents' media literacy, in order to achieve better effect in information dissemination and reception.

With the rapid development of economic globalization, the original competition basic has changed to be information, knowledge and culture. The culture factor has been the vital factor. The competitive strategy of a company can be duplicated, and under the environment that information spread rapidly, technological advantage can also be easily pursued, while, a company's culture are hardly to be copied. Corporate Culture refers to the core values, behavior traditions, management modes, enterprise spirit, moral criterions etc., in a enterprise, which are formed in the longtime management process, and are identified by the whole managers and employees. There are close relations between enterprise management mode and its mother traditional culture. just for this reason, enterprise cultures in different countries represent difference. On the aspect of traditional culture, Korea and China are both in the culture circle which is affected much by the Confucianism, so there are many same characters between the two. At the same time, because of Korea and China experienced different management system, it also has some differences. The paper uses comparison example, compare and analyze the Corporate Culture model of the Korea's LG and the China's Haier. Giving prospects and proposals for the development of Korea and China enterprise. At last, the author points out that the two countries’ corporate culture should study each other. And for the development of both, these two points should be paid attention: absorbing essence of traditional culture and adjusting oneself with the change of time and environment.

본 연구는 외래문화를 도입할 때 자국민들이 받아들일 수 있는 정도, 한중 간 분쟁해결에 대한 인식, 중국 문화콘텐츠 이용 정도, 중국 국가지도자인 시진핑에 대한 인식과 태도를 살펴보고, 이러한 변인들이 한국인들의 중국에 대한 태도와 방문의도에 어떠한 영향을 미치는지 알아보고자 한다. 그에 따라 양국 간의 우호적인 관계 회복에 필요한 요소들을 제시하고자 한다. 연구를 위해 총8개의 독립변인을 선택하여 위계적 회귀분석을 통해 가설을 검증하였다. 독립변인으로는 다른 나라의 문화를 받아들이는 정도로서 문화유입 수용성과 국가 간의 분쟁문제해결에 대한 인식, 중국 콘텐츠 이용 정도를 선택하였다. 국가지도자 이미지 관련변인으로는 시진핑 공신력과 시진핑에 대한 태도를 활용하였으며, 추가적으로 기본적 인구통계학적 변인인 성별, 연령 등을 사용하였다. 수집된 자료는 SPSS 21.0을 사용하여 분석하였다. 문화유입 수용성과 중국 콘텐츠 이용, 그리고 시진핑에 대한 태도가 중국 국가태도에 긍정적인 영향을 미치는 것으로 나타났다. 또한 연령, 분쟁문제해결 인식, 중국 콘텐츠 이용, 시진핑에 대한 태도가 중국 방문의도에 정적인 영향을 미치는 것으로 검증되었다. 결과적으로 연구 내에서 타국의 문화와 지도자 이미지에 대한 인식은 해당 국가에 대한 태도와 방문 의도에 영향을 미치는 것으로 확인하였다. 본 연구는 국가브랜드를 형성하는 요소로 문화와 지도자의 역할을 제안함으로써 연구와 실무에 시사점을 제공하고자 한다. The study sought to explore the impact of Koreans' cultural awareness of China and Chinese national leader Xi Jinping's perception of China on attitudes and willingness to visit China. As a demographic variable, gender and age were used, and cultural inflow acceptance variables were utilized as a degree of acceptance of culture in other countries. In the event of trouble-fighting among countries, the perception of problem-solving was also chosen as one of the variables, and the level of use of Chinese content was prescribed in the amount and frequency of Korean people using Chinese cultural products. Finally, regarding the national leader's image, Xi Jinping's public confidence and attitude toward Xi Jinping were utilized. A total of eight independent variables have an impact on China's state attitude and willingness to visit China. Tests of hypotheses using hierarchical regression have shown that acceptance of culture, use of Chinese contents, and attitude toward Xi Jinping have positive effects on China's national attitude. As a result, the better the cultural perception of China and attitude toward Chinese leader Xi Jinping, the more positive China's attitude and willingness to visit the country is overall. It aims to provide implications for research and practice by proposing the role of culture and leader as elements that shape the national brand.

Linear active disturbance rejection control with torque compensation for electric load simulator

Liu, Haitao,Liu, Huarong,Shan, Xianlei The Korean Institute of Power Electronics 2021 JOURNAL OF POWER ELECTRONICS Vol.21 No.1

This study proposes a design of an inner control loop for the load torque control of an electric load simulator (ELS), which is specifically designed to simulate load torque (i.e., load) for mechanical equipment. By mainly drawing on linear active disturbance rejection control, a mechatronic model-based inner loop controller of ELS is designed using measured torque to reduce the complexity of the estimator. A phase-locked loop observer is introduced to suppress the negative effects of the measurement error, thereby resulting in good performance for surplus torque suppression and the dynamic behavior of the control system. Simulations and experiments on a prototype machine are performed to verify the effectiveness of the proposed control method.

Chronic cough is very common in respiratory clinics, and no effective drugs are available. Schisandra chinensis (Turcz.) Baill. (S. chinensis), an important traditional Chinese medicine, has been extensively prescribed for patients with a persistent cough. Preliminary research indicated that 95% ethanol extracts (EE) of S. chinensis showed remarkable antitussive activity in guinea pigs exposed to cigarette smoke (CS). To find out the antitussive ingredients of S. chinensis, EE was divided into four fractions according to the polarity: petroleum ether extract (PEE), ethyl acetate extract (ECE), n-butyl alcohol extract, and residue extract. The antitussive, antioxidant, and anti-inflammatory effects of the four fractions were evaluated in a guinea pig model of cough hypersensitivity induced by CS exposure. Eighteen main constituents of the two effective fractions, PEE and ECE, were identified using ultra-high-pressure liquid chromatography electronic spray ion time-of-flight mass spectrometry. The cough inhibition activities of compound 1, 3, 9, 10, 17 were evaluated on citric acid induced acute cough guinea pigs. The results showed that the antitussive activity of EE was almost all contained in PEE and ECE. The 16 major peaks in PEE were identified as 15 lignans (1–12 and 14–16) and 1 triterpene (compound 13), and 3 major peaks (1, 17, and 18) in ECE were also identified as lignans. Three doses of five compounds brought about a significant decrease in number of cough efforts (P < .01), and the cough inhibition rates were between 40.9% and 85.1%. Therefore, lignans are the antitussive ingredients of S. chinensis.

Liu, Xiao-Rong,Xu, Jie,Wang, Yi-Min,Ji, Ming-Suo,Liu, Fu-Shan The Korean Society of Pharmacology 2016 The Korean Journal of Physiology & Pharmacology Vol.20 No.6

Paeoniflorin (PAE) is the most abundant compound in Xuebijing injection widely used to treat sepsis. We aimed to investigate effect of PAE on expression of soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) in a rat model of sepsis. Wistar rats were divided into Normal, Model, and PAE groups (n=20 each). Endotoxin was administrated at 5 mg/ml/kg in Model and PAE rats to establish rat sepsis model. 1 h after endotoxin administration, PAE was administrated at 4 ml/kg in PAE group once per day for 3 days. Routine blood tests and biochemical indexes were assessed, including aspartate aminotransferase (AST) and creatine kinase-MB (CK-MB). The plasma sTREM-1 level was measured using quantitative ELISA. At the end of experiment, the small intestine, liver, kidney and lung were subjected to pathological examinations. A rat model of sepsis-induced multiple organ dysfunction syndrome (MODS) was established successfully with endotoxin administration (5 mg/ml/kg), evidenced by histo-pathological examinations, routine blood tests and biochemical indexes: platelet count decreased and white blood cell count increased (p<0.05), CK-MB and AST increased (p<0.05). PAE treatment significantly reduced the plasma levels of AST, CK-MB, and sTREM-1, compared to Model group (p<0.05). Meanwhile, sepsis-induced damages in the liver, lung, stomach and intestinal mucosa were also markedly ameliorated by PAE treatment. PAE demonstrated a significantly protective effect in a rat model of sepsis by decreasing plasma sTREM-1 level, reducing inflammation, preventing MODS and protecting organ functions.

Based on the signal hypothesis, the optimal price range and the equity expansion hypothesis, this paper selects the ChiNext data from 2014 to 2019, using logistics regression model to study the factors influencing the high send turn of ChiNext listed companies. The results show that the development potential, the stock price at the end of the year, the size of the stock capital and whether or not the listed companies are high send turn have a significant impact. Based on the signal hypothesis, the optimal price range and the equity expansion hypothesis, this paper selects the ChiNext data from 2014 to 2019, using logistics regression model to study the factors influencing the high send turn of ChiNext listed companies. The results show that the development potential, the stock price at the end of the year, the size of the stock capital and whether or not the listed companies are high send turn have a significant impact. To verify the robustness of the main result, we use the return on total assets as a measure of development potential, and have consistent results which hypothesis 1,2 and 3 are still valid. In the control variables, the variable coefficient sign is basically the same, the coefficient sign of the cash generated by each share of operating activities is changed from positive sign to negative sign. The results of this paper represent that the stock price of ChiNext listed companies at the end of the year has a significant impact on whether or not enterprises carry out high send turn. The higher the stock price at the end of the year, the more likely that the ChiNext listed companies will implement the high send turn program. The size of the capital stock of the listed companies in ChiNext has a significant impact on whether or not the enterprises carry out high send turn.

Fracture toughness enhancement of epoxy resin reinforced with graphene nanoplatelets and carbon nanotubes

Shan-Shan Yao,Chun-Liu Ma,Fan-Long Jin,박수진 한국화학공학회 2020 Korean Journal of Chemical Engineering Vol.37 No.11

Graphene nanoplatelets (GNPs)/silane-coupling-agent-treated GNPs (KH- GNPs) and hydroxyl multi-walled carbon nanotubes (MWCNTs-OH) were added as reinforcing agents to an epoxy matrix, diglycidylether of bisphenol- A (DGEBA), to improve the fracture toughness of DGEBA. The influence of the MWCNT-OH fraction on the thermal and flexural properties, fracture toughness, and morphology of the DGEBA/GNP/MWCNT-OH and DGEBA/ KH-GNP/MWCNT-OH nanocomposites was investigated. The results indicate that the fracture toughness of the DGEBA/KH-GNP/MWCNT-OH nanocomposites increased from 1.09 to 1.46MPa·m1/2, which is 33.9% greater than that of pristine DGEBA. Analysis of the fracture surfaces of the nanocomposites showed a rough morphology with numerous tortuous and river-like structures. In addition, the MWCNTs-OH were slightly pulled out or broken in the epoxy matrix during the fracture toughness tests.

Liu, Jing,Liu, Pei-Fang,Li, Jun-Nan,Qing, Chun,Ji, Yu,Hao, Xi-Shan,Zhang, Xue-Ning Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.15

Background: A dense breast not only reduces the sensitivity of mammography but also is a moderate independent risk factor for breast cancer. The percentage of Western women with fat breast tissue is higher aged 40 years or older. To a certain extent, mammography as a first choice of screening imaging method for Western women of this group is reasonable. Hitherto, the frequency and age distribution of mammographic breast density patterns among Chinese women had not been characterized. The purpose of this study was to investigate the frequency and age distribution of mammographic breast density patterns among a group of Chinese screening women and breast cancer patients in order to provide useful information for age-specific guidelines for breast cancer screening in Chinese women. Methods: A retrospective review of a total of 3,394 screening women between August and December 2009 and 2,527 breast cancer patients between July 2011 and June 2012 was conducted. Descriptive analyses were used to examine the association between age and breast density. The significance of differences of breast density between the screening women and the breast cancer patients was examined using nonparametric tests. Results: There was a significant inverse relationship between age and breast density overall (r=-0.37, p< 0.01). Breast density of the breast cancer patients in the subgroups of 40-49 years old was greater compared with that of the screening women, the same in those aged 50-54 years and in those 55 years old or older, less than in the screening group. Conclusions: With regard to the Chinese women younger than 55 years old, the diagnostic efficiency of breast cancer screening imaging examinations may be potentially improved by combining screening mammography with ultrasound.
