The mismatch between low-quality content images and reproducing them on high-definition displays may cause visually induced human health problems. We carried out an experiment and a questionnaire to measure participants’ feelings of strangeness, discomfort and sickness in viewing a low-quality video clip presented on a high-definition display. Then we compared the results with the case of a high- quality video clip using the same display. We found that low- quality images can cause certain health problems depending on viewers’ ages. For older people such images can cause eye focusing problems rather than general symptoms, whereas for young and middle-aged people they cause both eye focusing problems and general symptoms such as discomfort and fatigue.","PeriodicalId":350703,"journal":{"name":"2020 15th International Conference on Computer Science & Education (ICCSE)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123863523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

China places great emphasis on establishing students thinking mode in digital environment, who can use information technology to solve problems and have the sense of social responsibility. In 2017, the Ministry of Education published a revised version of \"High School Information Technology Curriculum Standard\", which clarifies the information key competency, reconstructs the content and module of the high school information technology curriculum. In order to enable high school students to develop information key competency, information technology teachers’ key competency should be improved at first. This promotion needs to be accompanied by a systematic reform of pre-service cultivation. It is urgent to strengthen the training of information key competency of students majoring in computer education, who will be the information technology teachers in the future. This paper focuses on the information key competency of students majoring in computer education and analyse the present problems in the existing talent cultivation. Furthermore, we put forward the systematic reform measures for computer education major.","PeriodicalId":350703,"journal":{"name":"2020 15th International Conference on Computer Science & Education (ICCSE)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123914946","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To solve this problem, we introduce the concept of gamification into the compiler principle course for teaching aids, and design the card game called Into the Stack for the LR parsing algorithm, an important theory that must be mastered by students. When playing the game, players think over the quickest way to reduce their hands, which is based on the \"shift-reduce\" actions in LR parsing. Simulating such core actions of LR algorithm in this game, the whole abstract theory and algorithm has been demonstrated in a way of entertainment. It would help learners overcome their fear of theoretical knowledge, stimulate their interest in learning theories and enhance their ability of applying algorithms. Applied in realistic compiler principle courses, this game and such teaching method have achieved satisfactory teaching results.","PeriodicalId":350703,"journal":{"name":"2020 15th International Conference on Computer Science & Education (ICCSE)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124058095","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, CNN with extensive calculation is not suitable for the mobile terminals. In this paper, lightweight convolution neural network MobileNet is modified as backbone network for small object detection based on the Zynq platform. A method of data bypass is proposed which reserves shallow feature map information to the last convolutional layer, with which the detection accuracy increases by 8%. Additionally, 16 x 4 Wallace tree addition tree is designed instead of the original two-operand addition tree generated by Vivado HLS. The usage of hardware resources is reduced by 26%. The detection accuracy of the entire acceleration system is 73.7% and the FPS is 28.

However, the decision of the key positions in the overtaking process ignored. Based on the existing overtaking models, this paper proposes the overtaking feasibility decision making ability of key position of overtaking process, as well as lane change decision, and adds the vehicle operating characteristics to form a complete set of different speeds for different vehicles. The model is designed for the purposes of location overtaking feasibility decision, to verify the effectiveness of the established decision model algorithm. The results show that the overtaking time and distance of the two-lane highway are closely related to the vehicle type, overtaking speed, overtaking vehicle, speed of the overtaking vehicle and the speed of the opposite vehicle. In consideration of the moving characteristics of the vehicle, different vehicles need to overtake, and the overtaking time and distance are different, and multiple decisions are made at key positions in the vehicle overtaking process. The experimental results show that the obtained results are significantly in line with the actual overtaking phenomenon.","PeriodicalId":350703,"journal":{"name":"2020 15th International Conference on Computer Science & Education (ICCSE)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115332149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
