Research on Teaching Methods of Flight Control Principles

With the rapid development of China’s civil aviation industry,the teaching method of operating knowledge of flight principles has changed greatly,which creates a good implementation environment to improve the safety of civil aviation in our country.At present,the main training content of air route transport pilots in China is basic aviation theory,initial flight training,airline modification,etc.The principles of flight control are an important part of basic aviation theoretical knowledge training,which will involve a large number of flight technology training content,instructors will also be based on the pilot type.Teaching flight control theory and practical knowledge requires relatively high theoretical learning ability of students,and the learning effect of this part of theoretical knowledge will directly affect the quality of subsequent learning,but also directly affect the effectiveness of flight training.This paper focuses on the analysis of the basic concepts of flight control,studies the existing problems in the teaching of flight control principles,summarizes the teaching measures of flight control principles,aiming to provide a reference to teaching personnel.

How Does Vocabulary Knowledge Affect Chinese EFL Learners' Writing Quality in Web-based Settings?—Evaluating the Relationships Among Three Dimensions of Vocabulary Knowledge and Writing Quality

This study investigated the relationships among different dimensions of vocabulary knowledge （passive, controlled active and free active vocabulary knowledge） and how they affect EFL learners＇ writing quality. Participants were a whole class of web-based English learners （N = 31） of tertiary level in the Chinese mainland. The results show that free active （above 2000） vocabulary knowledge has a much stronger correlation with controlled active than passive vocabulary knowledge, and writing quality has a stronger correlation with free active vocabulary knowledge than with the other two dimensions of vocabulary knowledge.

Anxiety and depression among epilepsy patients in low-risk areas for COVID-19 in the northern part of Guizhou Province,China,during the COVID-19 pandemic

Background:This study was aimed to investigate whether patients with epilepsy(PWE)have higher depression and anxiety levels than the normal population in low-risk areas for coronavirus disease 2019(COVID-19)in the northern part of Guizhou Province,China,during the COVID-19 epidemic,to evaluate their knowledge on COVID-19,and to analyze related factors for the psychological distress of PWE at this special time.Methods:The survey was conducted online from February 28,2020 to March 7,2020 via a questionnaire.PWE from the outpatient clinic of epilepsy of the Aflited Hospital of Zunyi Medical University,and healthy people matched for age and sex,participated in this study.Mental health was assessed via a generalized anxiety self-rating scale(GAD-7)and the self-rating depression scale(PHQ-9).The knowledge of COVID-19 in both groups was investigated.Results:There were no significant differences in the general demographics between the PWE and healthy control groups.The scores of PHQ-9(P<0.01)and GAD-7(P<0.001)were higher in the PWE group than in the healthy group.There was a signifcant difference in the proportions of respondents with different severities of depression and anxi-ety,between the two groups,which revealed significantly higher degree of depression and anxiety in PWE than in healthy people(P=0,P=0).Overwhelming awareness and stressful concerns for the pandemic and female patients with epilepsy were key factors that affect the level of anxiety and depression in PWE.Further,the PWE had less accu-rate knowledge of COVID-19 than healthy people(P<0.001).There was no statistically signifcant difference between the two groups in the knowledge of virus transmission route,incubation period,susceptible population,transmis-sion speed,clinical characteristics,and isolation measures on COVID-19(P>0.05).PWE knew less about some of the prevention and control measures of COVID-19 than healthy people.Conclusions:During the COVID-19 epidemic,excessive attention to the epidemic and the female sex are factors associated with anxiety and depression in PWE,even in low-risk areas.
