In the process of engineering education certifification, some universities have explored the evaluation of
achievement degree based on the curriculum’s support for the graduation requirements. Learning from the engineering
education certifification in universities, we do the evaluation of achievement degree in the higher vocational mobile
application development course, and apply the evaluation results to the dynamic diagnosis and improvement, the
periodical diagnosis and improvement, the development of students’ abilities. On the one hand, it can objectively evaluate
the teaching effffect of teachers and students' learning effffect, and on the other hand, it can provide a reliable basis for
teachers to continuously improve their teaching work.

A real-time facial expression recognition based on OpenCV and Dlib model is proposed in this paper, which
avoids low recognition rate and complex extraction process in traditional methods and complex model and poor real-time
in deep learning-based methods. First, OpenCV is used to capture and pre-process images in real time. Then the Dlib
model is applied to calibrate the facial key points in the acquired face image. Finally, fifive indexes proposed in the paper,
i.e., eyebrow tilt degree, eyes open degree, upper lip to nasal tip height ratio, mouth width ratio and mouth height ratio are
combined to recognize expression. Besides, a system interface with simplifified operation is built to enhance the
practicability of the proposed method. Experiments show that the accuracy of the proposed method is above 96%, which
verififies its effffectiveness.

Exploration on Ideological and Political Education of Fundamentals of Program Design in IoT Major
PAN Mei-qin ZHU Fa-cai PENG Hai-ling ZHOU Yuan
Computer & Telecommunication    2023, 1 (1-2): 22-26.   DOI: 10.15966/j.cnki.dnydx.2023.z1.007

The ideological and political objectives of Fundamentals of Program Design condense the dual main lines of
"self-cultivation" and "talent" moral and technical courses, defifine the three-step value internalization of "personal
accomplishment, professional quality, ideals and beliefs", and integrate the four dimensions of teaching content, teaching
environment, teaching methods, and humanistic education into ideological and political education. In the teaching
process, the ideological and political quality goal of "striving for excellence, diligent learning and good thinking, unity
and innovation, dedication to work, self-cultivation and strengthening the country" runs through. A measurable and
evaluable learning evaluation system containing ideological and political literacy goals is built, so that the ideological and
political education of the curriculum can be implemented to all members, the whole process and all directions.

Fatigue driving is an invisible killer of road traffic safety. A fatigue driving detection system based on deep learning is pro
posed in this paper to ensure the high efficiency and accuracy of detection. First, OpenCV is applied to gray preprocess the collected
image. Second, directional gradient histogram is used to extract feature and the pre-trained Dlib model is applied to calibrate 68 face
feature points. Finally, the improved detected algorithms of blink, yawn and nod are used to calculate the length width ratio of eyes
and mouth and head posture Euler angle, respectively, and compare with its corresponding threshold to determine whether the driver
is in fatigue state and take early warning measures. Experiments show that the proposed system has 97% accuracy, verifying its ef

Research on a Three-layer Extraction and Anti-overfitting Gesture Recognition Algorithm
Based on Neural Network CNN
SHEN Ya-ting ZHANG Wei-jun BAI Yu-xin
Computer & Telecommunication    2023, 1 (3): 49-54.   DOI: 10.15966/j.cnki.dnydx.2023.03.007
Abstract56)            Save
Based on the CNN model, a gesture recognition algorithm named Add_Layer_CNN (A_L_CNN for short) is proposed,
which is a three-layer extraction and anti-overfitting gesture recognition algorithm based on neural network CNN. A_L_CNN changes the single-layer convolution pooling in the traditional CNN model to three-layer convolution cubic pooling structurally, and adds the Dropout (random deactivation) layer to prevent overfitting. A_L_CNN is compared with traditional CNN and SVM. Experimental results in multiple test sets show that the average accuracy of the proposed A_L_CNN model is about 98.56%, that of the traditional CNN model is about 96.11%, and that of the SVM model is about 87.25%. Therefore, the accuracy of the proposed A_L_CNN model is higher.

Curriculum ideology and politics is an important concept of educating people in the new era, and it is a hot issue
in the teaching reform of Chinese universities. At present, the ideological and political teaching of programming courses is
in the development stage, and there are still problems such as the content of teaching materials is not new, the quality of
teachers is not uniform, the teaching methods are not systematic, and the teaching resources are not perfect. The existence
of these problems prevents the ideological and political teaching of the course from better reflflecting the value orientation
of the course. In this regard, this paper introduces the ideological and political connotation of the program design course,
and puts forward the ideological and political implementation path of the program design course that integrates the value
of the course. Difffferent dimensions such as innovative teaching methods discuss how to reflflect the value of the course, and
introduce the practical process and effffect in actual teaching. Only by improving teachers' ideological and political
teaching ability, and innovatively designing teaching materials, teaching content and resources, teaching methods and
teaching evaluation mechanisms, and building a "new form, three-dimensional, collaborative education mechanism", can
the curriculum value of program design be better highlighted , to give full play to the educational potential of curriculum
ideology and politics.

E-government is an important component of digital China and one of the important issues of the Party and the state in the
construction of infrastructure and the living level of people. To promote the construction and development of Chinese egovernment by studying the evolution and development model of e-government, it is of great significance to promote the development of digital economy and digital society. From the multi- dimension information of the background of the times, policy measures, application practice and technological innovation, the multi-dimensional spiral model of Chinese e-government evolution and development is emphatically constructed. From the aspects of problem- oriented proposition, model theory construction, model practice analysis, model application expectation, etc., the paper pushes forward and reveals the path of "technological innovation ? application driven? time policy>>>value for all" path mode in the evolution and development of e-government in China layer by layer. It also analyzes the new trend of the development of core technology framework of digital government in the future. The paper constructs a multi dimensional intertexture and spiral evolution model of Chinese e-government, and according to the model, it reveals the evolution and development path mode of Chinese e-government.
