## Abstract

Nursing is an important task in modern medical treatment, which can assist patients in the treatment and rehabilitation process. Nursing practitioners’ skills and mentality can affect patient recovery and the speed of treatment. Therefore, there are already a large number of colleges and universities to carry out nursing teaching work. However, the current nursing teaching work still adopts the traditional teaching mode, which is no longer in line with the nursing work of the present era. Nursing teaching not only imparts nursing expertise to students, but it also requires higher practical ability. This study considers the integration of short video technology and text teaching mode into the teaching work of nursing. This study also used the transformer method to extract and predict the characteristics of nursing knowledge, nursing actions, and student satisfaction in short nursing teaching videos and texts. This study also explores the temporal characteristics existing in short videos of nursing teaching. The results show that the T-CNN-L method has higher accuracy than the T-CNN method in predicting the relevant features of nursing teaching short videos. The T-CNN-L method can also accurately and efficiently extract and predict nursing knowledge features and nursing action features.

## 1. Introduction

With the continuous improvement of living standards, the level of medical care also continues to improve. Nursing is an important stage in patient recovery and treatment. Effective nursing work and the attitude of nursing staff can affect the recovery process of the patient and the degree of treatment of the condition [1, 2]. Therefore, the method of nursing and the professionalism of nursing are a stage that cannot be ignored for medical treatment. For patients, most of the time is in the process of being cared for. It requires effective nursing work, both during the initial hospitalization phase and after the surgical phase. Therefore, the learning and teaching process of nursing is particularly important. The scope of nursing professional learning is also relatively wide because the nursing mode and nursing methods required by different diseases are different. There is a gap between the teaching work of nursing and traditional disciplines [3, 4]. Nursing students not only need to learn professional nursing knowledge and nursing actions, but also focus on practice. Professional nursing knowledge is the foundation of nursing practice. Through textbooks, nursing students can only learn the basic knowledge and precautions of nursing [5, 6]. Successful nursing work also requires more practice and internship process, which can improve the practical and clinical nursing ability of nursing students. At present, most colleges and universities use the form of textbooks and PPT to transmit relevant knowledge, and nursing students will also be exposed to practical links [7, 8]. However, the time for nursing students to be exposed to the practice link is relatively small, so it is necessary to consider other ways to integrate them into the teaching work of nursing [9, 10]. With the advancement of science and technology, video technology and text technology can be well transmitted through the Internet, and students or teachers can obtain more relevant video and text information about nursing knowledge through Internet technology.Video technology is a technology that integrates vision and hearing. It can display relevant information in the form of images and sounds. At the same time, video technology can help nursing students to fully watch and learn the movements in the nursing process. Compared with textbooks and PPT teaching methods, visual teaching methods can be more easily accepted by nursing students [11, 12]. This video technology has been used in teaching work in many disciplines. It has also been proven that video teaching methods can adequately impart knowledge. Unlike the textbook method, video technology only transmits more important knowledge, it can transmit the nursing professional knowledge in a comparatively complete manner. For a more practical discipline such as nursing, video technology will be more helpful. However, related videos in nursing teaching have many complex features. The memory occupied by video is larger than that of the image method, and the short video of the nursing profession is also a kind of continuous information expression, which shows that the short video method of nursing teaching will have a lot of characteristics. Simple neural network methods cannot effectively extract the spatial and temporal features of short nursing teaching videos, which requires deepening the number of network layers. Therefore, this study considers the application of transformer technology to achieve the task of extracting short nursing teaching videos and text features.Artificial intelligence technology has been successfully applied in various fields for many years. It also exhibits some excellent algorithms [13, 14]. Among these algorithms, the most successful and mature algorithms are mainly Convolutional Neural Network (CNN) and Recurrent Neural Network (RNN) theory. RNN is mainly used in the field of speech recognition, which can extract time-related features and research objects. CNN is mainly used in the field of image recognition-related research objects, it can complete the mapping of input and output features and the task of spatial feature extraction of research objects [15, 16]. Although the CNN method can use the weight-sharing mechanism to reduce the amount of operation parameters, the RNN method still has a large amount of parameter operation. This will lead to a relatively long training and learning process and time of RNN, which will limit the depth of the number of layers of RNN, which also limits the scope of use of RNN and the accuracy of feature extraction. In order to increase the scope of use of RNN and increase the depth of RNN, researchers have successfully added the self-attention mechanism to the RNN network layer, which is the so-called transformer technology. Transformer technology is actually an encoder-decoder structure. The encoder and decoder also include feedforward neural network structures such as CNN and RNN [17, 18]. Transformer technology can further deepen the number of RNN network layers, which can also reduce the amount of parameters in the RNN learning and training process. For the short video and text feature extraction tasks of nursing teaching, the transformer technology can fully extract the relevant features of nursing teaching tasks on the basis of reducing the amount of parameters. Transformer techniques is a deep learning method that combines CNN and RNN methods, and it also includes an attention mechanism. This will further improve its accuracy and generalization ability in extracting features from short nursing teaching videos.The main task of this research is to use transformer technology to achieve feature extraction and related prediction in short nursing videos and text knowledge. This study designs a transformer structure according to the needs of nursing specialty feature extraction and analyzes the ability of this method in the extraction of nursing knowledge features, nursing action features, and student satisfaction features. This study presents research on transformers and nursing short videos and texts from five different aspects. Section1 mainly describes the importance of the nursing profession and the development background of transformer technology. Section 2 investigates the related research status of nursing and the research status of nursing teaching. The application of transformer technology in feature extraction of nursing short videos and the related structures and expressions of transformer technology is illustrated in Section 3. Section 4 presents the accuracy of the transformer technique in nursing short videos and text feature extraction through some statistical parameters. Section 5 is the last section to summarize and illustrate the value and significance of transformer technology for nursing teaching and research.


## 2. Related Work

Nursing is an important job in medicine, and it is a guarantee for patients to restore their health. Different patients have different requirements for nursing, which requires nursing students to master the common sense of nursing and nursing methods. Different conditions are treated differently. It is precisely because of the importance of nursing for the rehabilitation of medical patients that a large number of researchers have conducted research on the methods and methods of nursing. Hynes et al. [19] believed that there are still many needs to improve work efficiency and methods in the nursing work of intensive care, which is related to the speed and effect of recovery of patients with the disease. This study used a questionnaire to collect a large number of nursing-related data in the Australian intensive care unit setting. The findings suggest that the attitudes of nursing professionals and the psychological role of nurses can have a powerful effect on the rehabilitation and treatment of critically ill patients. This study suggests that nursing work should give more psychological care and a positive and optimistic nursing attitude to critically ill patients. The study also sheds light on how family care works. Al-Hakim et al. [20] studied investigated the relationship between nursing workload and job satisfaction, mainly from the perspective of psychological attitude and perception. It also uses the form of a questionnaire to study intensive care work in a large number of hospitals. It tested the relationship between nursing work and satisfaction using SPSS method and univariate measurement model. The research results show that there is a direct relationship between the psychological attitude of nursing work and nursing job satisfaction, and the perception of the author plays a certain moderating role. Using a quantitative approach to explore the relationship, the study allows nursing workers to see the key role between workload and satisfaction, which can also help increase their psychological motivation at work. Oikarainen et al. [21] present guidance on clinical safety and cultural aspects of nursing work for nursing students from diverse backgrounds. It believes that evaluating educational interventions will diversify the culture and language of nursing teaching, which will help nursing students deepen their knowledge and understanding of nursing work. It designed two different controlled experiments using data from two hospitals in Finland, and it examined the difference between the two using a repeated-measures mixed model. The results of the study show that improving teachers’ guidance ability can help improve students’ cognition of clinical nursing profession, and it can also increase their enthusiasm for nursing profession. It also has important implications for increasing the linguistic diversity that leads to teaching and for understanding the wishes of nursing students. Plaza et al. [22] believed that the growth of the Spanish immigrant population has changed the traditional medical care model, which has brought certain difficulties for nursing students. It also considers the literacy of nursing students to be important. It uses high-fidelity simulation to study ways and means to improve nursing student literacy. This study also employs a qualitative approach to explain phenomena. The results of the study show that the high-fidelity simulation method can improve the learning experience of nursing students, which can also improve nursing students’ care and understanding of patients with different cultural backgrounds, which is beneficial to the development of nursing work. This research also helps to improve nursing satisfaction and communication skills in nursing jobs. Martin-Delgado et al. [23] explore the student approach of clinical nursing students during COVID-19, and it mainly uses online clinical training to teach nursing students. It is mainly to improve the health education ability of nursing students. This study explores the changing roles of nursing students and the content of their training during the pandemic. It qualitatively investigates issues related to nursing students using survey methods. The results of the study found that clinical reductions did not bring much emotion to nursing work. Cognitive teaching is also an essential knowledge for nursing students for clinical practice. This study better guides nursing students’ learning styles and psychological changes during a period of COVID-19. The traditional nursing teaching work has certain defects. This study will use the T-CNN-L method to extract the temporal and spatial correlations in short nursing teaching videos. This is a more efficient and accurate way. It will save a lot of time resources.


## 3. Application and Research of Transformer in Nursing Short Video and Text Teaching

### 3.1. The Importance of Transformers in Nursing Teaching Application

This study mainly explores the role of short videos and text content on nursing teaching tasks. It is difficult to qualitatively and quantitatively analyze the ability and effect of nursing students to absorb short videos and text content, which makes it difficult to ensure that short videos and texts are important for nursing. At the same time, short videos and texts are a new way of teaching that is different from traditional books, which requires nursing teachers to fully explore the relevant nursing professional knowledge contained in nursing short videos and nursing texts. However, nursing short videos and texts will contain rich text knowledge, graphic knowledge, and video action knowledge, which requires nursing students and teachers to grasp the key content. Transformer can realize the extraction of short nursing videos and nursing text features and the mapping of complex relationships, which can help nursing students and teachers quickly absorb the nursing actions and key content of nursing knowledge contained in short videos and texts. This allows nursing students to learn and apply nursing-related knowledge and related nursing actions in a targeted manner. This can not only improve students’ awareness of nursing content, but also enhance students’ interest in learning nursing knowledge.


### 3.2. The Scheme Design of Transformer in Nursing Short Video Teaching and the Principle of Transformer

Different diseases have great differences in nursing expertise and nursing actions. This requires nursing students to learn more nursing knowledge and nursing actions. However, the task of nursing care in real life is more complex because everyone’s condition and physical state are different. Cumbersome nursing knowledge can easily make students lose interest in learning. This research mainly uses transformer technology to learn the characteristics of nursing knowledge, nursing action, and student satisfaction contained in nursing short videos and nursing texts. Transformer is also a kind of artificial intelligence technology. It also requires a large amount of data for training and testing, which can improve the accuracy of extracting nursing short videos and nursing text features. In this study, an intelligent feature recognition scheme of nursing short videos and text features was designed to achieve this purpose. Figure1 shows the application scheme of nursing short video and text features based on transformer technology. First, it needs to divide the collected dataset into three features: nursing knowledge, nursing action, and nursing student satisfaction, which will be used as the input layer of the transformer technology. Transformer technology is actually a structure that includes a variety of convolutional neural networks and long and short-term memory neural networks. After the nursing-related features are extracted, it can recommend nursing-related learning knowledge and actions to students and teachers using a computer system. In Figure 1, the transformer technique can not only extract the spatial features of nursing short videos, but it can also extract the temporal features of nursing short videos. This is mainly because short video technology is also a feature similar to the field of speech recognition, which contains relatively rich temporal features. When the weight and bias of this intelligent algorithm are determined, it can be applied in practical nursing teaching tasks. It only needs to provide short videos and textual knowledge related to nursing. In practical nursing teaching tasks, the optimal weights and biases in transformer techniques have been determined. When the test set is applied it does not go through the training and iterative process, it will directly perform the matrix calculation using the weights and biases.Figure 1
Transformer technology in nursing short video and text feature extraction process.


### 3.3. Principles of Transformer Technology and Related Structures

Transformer technology is also a kind of big data technology. It also uses the distribution of weights and biases to realize the prediction and feature extraction of related features. It can be applied to the feature extraction tasks of short videos and texts in the nursing profession. Transformer technology is a solution proposed to solve the training time comparison field problem of recurrent neural network (RNN), which is equivalent to adding an attention mechanism to the traditional neural network. Figure2 shows the basic structure of the transformer technology, which mainly consists of multiple layers of decoders and encoders. The input layer will be connected to the encoder, and the output layer will be connected to the decoder.Figure 2
Schematic diagram of the basic structure of transformer technology.Decoder and encoder are also common network structures. Each layer of decoder or encoder will contain CNN method and LSTM method, and one layer of encoder may contain multiple layers of CNN and LSTM layers. Transformer techniques add attention mechanisms to this encoder and decoder structure. Figure3 shows the detailed structure of the encoder and decoder. It can be seen from Figure 3 that the encoder mainly includes the attention mechanism layer and the feedforward neural network layer. The feedforward neural network layer can use the CNN method and the LSTM method to extract the spatial and temporal features of the research object. The decoder mainly includes three parts: attention mechanism layer, feedforward neural network layer, and encoding-decoding attention layer. Transformer techniques include CNN and LSTM structures, these two common deep learning methods are just an important part of transformer techniques. It will use CNN to form an encoder and decoder. It is the similarities and differences between CNN and transformer techniques.Figure 3
Detailed structure introduction of the encoder and decoder.


### 3.4. Transformer and Encoder-Decoder Expression Introduction and Working Process

In this study, in order to achieve the extraction of short nursing videos and text features, CNN and LSTM methods are used in the feedforward neural network layers in the encoder and decoder of the transformer. The detailed self-attention representation and the representation of the feedforward neural network layers are presented below.For the structure of the transformer, whether it is an encoder or a decoder, it is a superposition of an attention mechanism and a feedforward network layer. Expressions1 and 2 show a computational relationship between the attention mechanism layer and the feedforward network layer.(1)Zl=Layer−NormAnomaly−Attentionχl−1+χl+1,(2)χl=Layer−NormFeed−ForwardZl−1+Zl+1.It is similar to RNN and CNN neural networks, there is also an excitation function for attention. Expression3 shows the calculation method of the excitation function of the transformer technique. Expression 4 shows one way of computing the output layer of the transformer technique. It will do matrix operations.(3)Sl=SoftmaxQκTdmodel,(4)Z˙l=Slν.In the transformer technology, there is a distribution between different layers of the self-attention mechanism layer. This study uses the Gaussian distribution to process the distribution of the attention mechanism layer. Expression5 shows the Gaussian distribution function of the attention mechanism layer.(5)Gj−i;σi=12πσiexp−j−i22σi.For the transformer technology, the feedforward neural network layer can be a CNN or RNN method, which involves derivative calculations. The derivation calculation will process the existing features of nursing teaching short videos with the distribution of weights and biases. Expressions6 and 7 show the derivation process of the weights and biases of the feedforward neural network layer in the transformer technique.(6)Δωji=−η∂E∂ωji,(7)Δuij=−η∂E∂∂uij.Expression8 shows the loss function of the feedforward neural network in the transformer technique. It will be responsible for calculating the error between the predicted value and the actual value of the relevant features of nursing teaching short videos, and the iterative process of the feedforward neural network will iterate according to the direction of minimizing the loss function. The loss function will calculate the error distribution between the predicted value and the actual value of a feature, and it is also a continuous process with iterations. The three kinds of feature data will be separately calculated for the loss function. The three characteristics do not mix.(8)E=12dout−Oreal2=12∑κ=1tdκ−Oκ2.Expressions (9) and (10) show the loss function calculation method for the self-attention layer of the transformer technique. This is somewhat different from common loss functions.(9)LTotalχ,p,Sdetach,−λ,χ¯,(10)LTotalχ,p,S,λ,χ¯.For the feedforward neural network of the transformer, it requires convolution operations. Expression11 shows how the convolution of the feedforward neural network layer is calculated.(11)V=conv2W,X,‶valis″+b.

## 4. Result Analysis and Discussion

This research mainly uses transformer technology to study the related characteristics of short videos and texts in the nursing teaching process. In the design process of transformer technology, the feedforward neural network structure used in this study is CNN and LSTM methods. These two algorithms belong to the category of big data technology, which requires a large amount of data of short nursing teaching videos and text features to support transformer technology for training and testing. In order to better analyze the important knowledge and characteristics of nursing teaching, this study divides the characteristics of nursing short videos and texts into three characteristics: nursing knowledge characteristics, nursing action characteristics, and nursing student satisfaction for related research. It considers data related to multiple medical specialties in Beijing as the dataset for this study. These datasets will be divided into a training set and a test set of nursing teaching features in a ratio of 7 : 3. In order to improve the parameters and network layers and other characteristics in the training process of nursing features, this study uses a part of the dataset in the training set as the validation set. The presence of a validation set can reduce the time in the nursing feature extraction process.In the process of extracting nursing short videos and text-related features using transformers, this study will consider the influence of with and without LSTM neural network layers. This is also a sufficient reason to illustrate the temporal characteristics contained in nursing short videos and nursing textual knowledge. In this study, the transformer technique with a single CNN feedforward neural network layer is marked as T-CNN, and the transformer technique with CNN and LSTM feedforward neural network is marked as T-CNN-L. First, the prediction errors of the T-CNN method in predicting the three characteristics of short nursing teaching videos and texts are shown in Figure4. From Figure 4, it can be seen that the prediction errors of the three characteristics of short nursing videos and texts are all about 3%. For the nursing knowledge characteristics of short nursing videos, this part of the prediction error has reached 3.12%. For the nursing action characteristics of nursing short videos and texts, this part of the prediction error has also reached 3.24%. Although the prediction errors of the three characteristics of nursing teaching short videos and texts are all within 5%, this only shows that the T-CNN method can predict the short video characteristics of nursing teaching, but the accuracy is relatively low.Figure 4
Prediction errors of short videos and text-related features in nursing teaching using the T-CNN method.This study uses the T-CNN-L method to study the temporal characteristics of short nursing teaching videos and texts. It also compares the difference in accuracy between T-CNN and T-CNN-L methods in predicting short nursing videos as well as text features. Figure5 shows the prediction errors of short nursing teaching videos and text-related features using the T-CNN-L method. It can be seen from Figure 5 that the prediction errors of the three characteristics of the short nursing teaching videos have been greatly reduced. This fully demonstrates that the T-CNN-L method has obvious advantages over the T-CNN method in predicting the relevant features of nursing short videos. This is mainly because the T-CNN-L method can fully consider the temporal features contained in short videos and text information. It is difficult for the T-CNN method to capture temporal correlations in short videos of nursing teaching. For the nursing action characteristics of short nursing teaching videos, the prediction error of this part is reduced from 3.24% to 2.48%. The prediction error of the nursing knowledge feature was reduced from 3.12% to 2.32%. The prediction error of learning effect characteristics in short nursing teaching videos was reduced by 0.97%, and the reduction rate of nursing action characteristics was 0.76%. Nursing knowledge characteristics decreased by 0.8%. The prediction errors of these three features were reduced by a relatively large margin. This fully demonstrates the effectiveness of the T-CNN-L method in predicting the relevant features of short nursing teaching videos.Figure 5
Prediction errors of nursing teaching short videos and text features using T-CNN-L method.Figures4 and 5 compare the accuracy and difference of two types of transformer techniques in predicting and extracting nursing short videos and text features in the form of mean error. Through the above study, we determined that the T-CNN-L method was used to study the features present in nursing teaching. In order to fully study the differences in the prediction of the three teaching characteristics by the T-CNN-L method, this study used different statistical parameters to analyze the three characteristics of nursing teaching. First, Figure 6 shows the data distribution of nursing action features of short videos and texts of nursing teaching. In Figure 6, the red part represents the predicted value of the nursing action feature, and the green part represents the actual value of the nursing action feature. Overall, the trends and data values in the red areas are consistent with the green areas. It can be seen from Figure 6 that there is a certain degree of fluctuation in the data value of the nursing action, whether it is the predicted value of the nursing action or the characteristic value of the actual nursing action. In general, the T-CNN-L method can more accurately grasp the characteristic data values of nursing actions and the changes in nursing action characteristics in short nursing teaching videos. The distribution of the eigenvalues of nursing actions can prove that the T–CNN–L method has enough confidence to help nursing students to find the knowledge of nursing actions corresponding to different diseases.Figure 6
Predicted distribution of nursing actions in short nursing teaching videos and texts.Nursing teaching short videos will have more relevant nursing knowledge, and nursing students can extract relevant knowledge and characteristics from it. This study uses the T-CNN-L method to extract nursing knowledge from short nursing videos and texts. Figure7 shows the data distribution of nursing knowledge in nursing short videos. There is a large fluctuation in the prediction errors of nursing knowledge features, which indicates that the number of different nursing knowledge features is different in the dataset. It can also show that the data in the test set is reasonably distributed. From Figure 7, it can be seen that most of the predicted values of nursing knowledge are distributed within 2%, and some predicted eigenvalues of nursing knowledge are distributed below 1%. Only a small subset of nursing knowledge characteristics had prediction errors distributed above 4%. Most of the errors are distributed within a reasonable range for nursing teaching tasks. Part of the reason for the larger error may be that the characteristics of this part of nursing knowledge are special and the characteristics of this part of nursing knowledge are relatively sparse in the training set. Through the error distribution of nursing knowledge, it can be seen that T-CNN-L can effectively help nursing students and teachers to extract useful nursing-related knowledge. Students in nursing teaching can not only observe detailed nursing actions through short videos, but also efficiently acquire nursing professional knowledge through the T-CNN-L method. The reason for the large differences in nursing knowledge characteristics of different groups may be that the disease characteristics in the dataset are relatively small, which limits the learning and training of transformer technology.Figure 7
Prediction error distribution of nursing knowledge existing in nursing teaching short videos and texts.In the short nursing video and text teaching scheme designed in this study, there is a teaching feedback mechanism. It provides feedback on student satisfaction to teachers and students based on student performance as well as clinical performance. This method not only allows students to fully understand their learning level of nursing knowledge, but also shows the students’ adaptability to this transformer technology. Figure8 shows the data distribution of student satisfaction features of short nursing videos and texts. Figure 8 introduces the effect of T-CNN-L on predicting student satisfaction features in the form of a predicted box plot. If the distribution and form of the box plots are consistent, this can illustrate the reliability of the T-CNN-L method in predicting the characteristics of student satisfaction. From Figure 8, it can be seen that the predicted value of the short nursing video and the text’s student satisfaction characteristics are in good agreement with the actual value. This also fully proves that the T-CNN-L method can extract the characteristics of students’ satisfaction from nursing teaching programs. This is a beneficial feedback mechanism for both teachers and students. At the same time, the average value of student satisfaction in the short nursing teaching videos is in good agreement with the predicted average value.Figure 8

## 5. Conclusions

With the continuous improvement of medical levels and people’s requirements for living standards, nursing work has become an important part of medical work. Nursing work is not only related to the speed of the patient’s recovery, but it is also related to the level of recovery of the patient with the disease. Positive optimism and more professional nursing workers will have a positive effect on the recovery of patients with the disease. Nursing teaching work has also been carried out in many colleges and universities. However, there is still a big difference between nursing teaching work and traditional disciplines. Nursing teaching work not only needs to learn nursing professional knowledge, but also needs more input into nursing practice. Nursing teaching short videos contain relatively rich features. Students can only perceive relevant nursing knowledge and nursing actions through sight and hearing, but it is difficult for students and teachers to grasp relevant important features, which is difficult to practice manually.This study integrates short video and text technology into nursing teaching work. At the same time, in order to carry out the teaching of nursing more efficiently, this study considers embedding artificial intelligence technology into the teaching of nursing. Considering the huge amount of data in short videos and texts of nursing teaching, this requires deeper network layers. Therefore, this study utilizes the transformer technique to solve this problem, which needs to take into account the self-attention mechanism. Through the above research, it can be found that the T-CNN-L method has higher accuracy than the T-CNN method in predicting and extracting short nursing teaching videos and text features. Although the T-CNN method can also predict the characteristics of nursing knowledge and nursing actions in short nursing teaching videos and texts, the maximum prediction error has reached 3.24%. For the teaching work of nursing, this is an unfavorable error value. This is because the T-CNN method does not fully extract the temporal features in short nursing teaching videos. After using the T-CNN-L method, the prediction error of nursing knowledge was reduced to 2.32%. The prediction error for nursing actions was reduced to 2.48%. The error of the learning effect feature is also reduced to 2.02%. The T-CNN-L method can effectively integrate short nursing videos and texts to assist nursing students in their learning. The T-CNN-L method can help people to identify and predict the characteristics of nursing knowledge and nursing actions in short nursing teaching videos. This is a more effective and rapid method, and it has high value.
