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.

유산산 ( Shan-shan Liu ),위오기 ( Oh-gie We ) 공주대학교 KNU 기업경영연구소 2010 기업경영리뷰 Vol.1 No.2

기업문화는 다양한 요인으로 구성되고, 이러한 구성요인들은 기업에 따라 차이가 있을 것이다. 이에 본 연구에서는 기업문화의 구성요인를 제시하고, 각각의 구성요인들이 어떠한 차이를 보이는지를 중국과 한국의 대표 전자기업인 Haier과 LG을 대상으로 실증분석하여 검증하고자 하였다. 조직문화유형의 구성 요인은 선행연구에 근거하여 리더십스타일, 기업시스템유형, 전략유형으로 구분하여 검증하였고, 기업의 핵심 역량과 구조적 특징에 관한 요인을 정리하여 인재, 기업규정, 기업내윤리로 구분하여 검증하였다. 설문조사는 중국 현지에서 실시되었으며, 현지기업인 Haier과 해외진츨기업인 LG의 종업원을 대상으로 2010년 5월 4일부터 5월 10일까지 실시하여 LG 94부, Haier 101부, 총 195부를 표본으로 분석을 실시하였다. 기업에 따른 조직문화유형의 인지 정도를 검증하기 위하여 t-test를 실시하였다. 결과를 살펴보면 전반적으로 LG의 평균값이 높은 것으로 나타나, t값의 대부분이 음수로 제시되었다. 기업문화유형은 리더십스타일, 기업시스템유형, 전략유형의 설문문항들을 기업유형분류에 의해 재정의하여 선행연구와 비교하기 위하여 친화적, 진취적, 성과지향적, 보존지향적 유형으로 구분하였다. 또한 요인분석 결과를 점수화하여 3가지 요인즉 기업규정을 중시하는 기업문화, 인재를 중시하는 기업문화, 기업내윤리를 중시하는 기업문화의 두 집단간 차이가 있는지 t-test를 실시하였다. 검증결과 두 집단의 차이가 있는 것으로 나타났다. 상기와 같이 LG의 평균값이 높은 것으로 나타나 t값은 모두 음수로 나타났으며, 모두 통계적으로 유의한 것으로 나타났다. 이상의 연구결과에서 살펴보면 LG와 Haier의 기업문화특성에 대한 인지정도의 차이는 전반적으로 LG 가 높은 것으로 나타나 선행연구의 결과와 상이하게 타나났다. 이를 전반적으로 해석하면 선행연구와 본 연구모두 LG가 Haier보다 상대적으로 높은 응답치를 보이고 있으나, 그 차이가 본 연구에서 보다 두드러지게 나타난 것으로 사료된다. 이는 표본의 차이, 실제적으로 양 기업의 조직문화의 차이, 최근 급변하는 경영환경에 대응하기 위하여 기업들은 성과를 중요시하고 있으며, 성과를 중요시하는 기업문화는 지속적으로 변화하게 되므로 이러한 차이에서 기인한 것으로 사료된다. 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.

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.

Influence of the camber trailing-edge wings on the motion performance of underwater gliders

Liu Yuhong,Xu Shixun,Tian Shan,Lan Shiquan,Deng Shihan,Liu Shuhe,Feng Dengxue 대한조선학회 2022 International Journal of Naval Architecture and Oc Vol.14 No.1

Wings are the main source of lift for Underwater Gliders (UGs) and play a decisive role in their motion performance. The wings of UGs are generally rectangular and symmetrical airfoils. In this study, a mini- UG with flexible camber trailing-edge wings was proposed and developed to investigate the influence of the trailing edge of the wings on the motion performance of UGs. Flexible deformation of the trailing edge was realized using a steer-by-wire actuator. The test results showed that the trailing edge of the wing could realize maximum upward/downward sloping angles of þ16/16. By combining computational fluid dynamics simulations and tank experiments, this study obtained the glide efficiency (in liftdrag ratio) and stable margins of a mini-UG with variable camber trailing-edge wings. The results showed that the angles of attack corresponding to the minimum lift-to-drag ratio were all negative in cases of downward sloping and positive in cases of upward sloping. Moreover, the suitable camber of the trailing edge, that is, downward-sloping trailing edge on descending glides and upward-sloping trailing edge on ascending glides, can not only greatly improve glide efficiency but also benefit flight stability. Tank experiments showed that the lift-to-drag ratio of the mini-UG with appropriate variable camber trailing-edge wings can be increased by at least 25% compared to those with a symmetrical airfoil.

Shan Zhong,Li-Ping Bai,Xiao-Dong Liu,Die-Yi Cai,Lee-Fong Yau,Chu-Qin Huang,Jia-Qi Zhang,Ke-Fang Lai,Nan-Shan Zhong 한국식품영양과학회 2021 Journal of medicinal food Vol.24 No.4

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.

The effects of paeoniflorin injection on soluble triggering receptor expressed on myeloid-1 (sTREM-1) levels in severe septic rats

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.

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.
