In recent years, the big model represented by ChatGPT has brought opportunities and challenges to the teaching of computer practice courses. The correct application of these tools can enhance the learning effect and the development of students' abilities, realizing the 'human-computer co-enhancement'. However, students may also utilize these models to complete programming assignments, which may lead to cheating, violate the principle of academic honesty, weaken students' motivation to learn and master skills, and may lead to 'innovation inertia syndrome', which is not conducive to the enhancement of independent design ability. The paper firstly comprehends the pattern of computer practice teaching, analyzes the positive, negative and uncertain impacts of ChatGPT on teaching and learning, and proposes targeted solutions, and then illustrates the specific implementation process of these measures through two practice cases, with a view to providing references to meet the challenges posed by the technology and to promote the harmonious development of education and technology.

Aiming at computer resources was limited and the total overhead of the system processing tasks was too high, this paper proposed an offloading strategy based on dynamic perception-hybrid artificial fish swarm（DP-HAFS） algorithm. First, it constructed a "local-edge-cloud" three-layer network architecture and adopted a fine-grained partial offloading mode; then, for the scenario where a terminal device covered by multiple base stations, this paper proposed a base station selection strategy to select the optimal base station; finally, it used the DP-HAFS algorithm to dynamically modify the unloading decision and got the best uninstall strategy. The simulation results show that the proposed offloading strategy can effectively reduce the total system overhead in a scenario with a large number of tasks. [ABSTRACT FROM AUTHOR]

Ternary optical computer（TOC） is a new architecture computer with a large number of processor bits and the characteristics of easily scaling, reconfigurable bit functions, and groupable bits. It has great potential for fast processing of massive or complex data. However, it is still in the early stage of application development exploration. To expand its application, this paper proposed a TOCSim design scheme for a simulator based on a ternary optical computer architecture. It simulates the TOC operation process in the form of software and implements its prototype on an ordinary PC. These operation processes mainly include the TOC processor reconfiguration strategy, processor bit allocation strategy, intermediate result decoding, and computing effect simulation. A comparison of the simulation effect graphs derived from the simulator proposed in this paper between the light graphs of the operation results on the TOC prototype shows that the design scheme of the simulator is correct and feasible.

This paper proposed a method for the residency of the RT-Thread real-time operating system based on the general embedded computer(GEC) architecture to address the issues of slow compilation speed and poor reusability caused by the complexity of the real-time operating system kernel in embedded applications. On the basis of reasonable storage space allocation, the method achieved the sharing of interrupt service routines, providing users with function call services for both low-level drivers and software application layers. Finally, the residency method was tested using the D1-H application processor as an example. And the results demonstrate that it achieves physical isolation between the system kernel and application programs, resulting in shorter compilation time and higher development efficiency. This method provides a foundation for the timeliness, convenience, and simplicity of embedded program development. [ABSTRACT FROM AUTHOR]

Intelligent question answering based on reading comprehension refers to letting computers read and comprehend texts like humans, extracts the text information and answers corresponding questions. The pre-training model RoBERTa-wwm-ext uses the extracted original fragments as the answers to the questions, but this method can’t solve the two situations that the answer fragments don’t exist in the original text or need to reply to the original text after summarizing. The pre-training model is used for generative model training, which can solve the problems that need to summarize the original text to a certain extent. Therefore, this paper improved the method of only using RoBERTa-wwm-ext model to extract answers. On this basis, it integrated the generative question answering model based on RAG model to answer questions that could not be handled by Roberta-wwm-ext and other extraction models. At the same time, this paper absorbed the advantages of PGN model, improved RAG model, and obtained RPGN sub model, which could make better use of reading and understanding articles to generate reasonable answers. Therefore, this paper proposed a fusion model of RPR（RAG, PGN, RoBERTa-wwm-ext）,which could be used to deal with both extractive question task and generative question answering task at the same time.

Object tracking is an important topic in computer visual directions, where scale changes, deformation and rotation are difficult to resolve in the field. For the challenging problems faced in the above track, based on existing Siamese network algorithms, this paper proposed multi-layer feature fusion and parallel self-attention Siamese networks (MPSiamRPN) for visual tracking. Firstly, MPSiamRPN used the modified ResNet50 to extract features from the template image and the search image. In order to deal with the loss of some features caused by the deep network, it proposed a multi-layer feature fusion module to fuse the features of the last three layers of ResNet. Secondly, it introduced the parallel self-attention module, which was composed of channel self-attention and spatial self-attention. The channel self-attention could selectively emphasize the beneficial channel features for tracking, and the spatial self-attention could learn the rich spatial information of the target. Finally, it proposed the region proposal network ( RPN) to perform classification and regression operations to determine the location and shape of the target. Experiments show that the MPSiamRPN can achieve competitive results on OTBlOO and VOT2018 test datasets. [ABSTRACT FROM AUTHOR]

In order to achieve an accurate description of the urban road network morphology, the morphological characteristics of the road network are divided into two categories: geometric shape and topological structure for analysis. For each type of structural characteristics, corresponding quantitative description indicators and calculation methods are proposed, combined with the computer aided analysis techniques such as Origin and DepthMapX, this paper quantitatively analyzes and compares 8 samples of 4 types of road networks which are common in modem cities and displayed in different development stages. The results show that: (1) compared with the traditional or single - type indicator research, the two types of indicators further show the difference between the internal relationship and composition of the road network. The effect is particularly significant when distinguishing the road network in the historical old city and the road network in the peripheral area. (2) There is a mutual feedback effect between the two types of morphological characteristics : the cell rate, integration and intelligibility show a certain positive correlation. (3) The naturally formed road network appears to have a structure complex, but easier to understand after topological deformation. [ABSTRACT FROM AUTHOR]

As for the drivers' eye open degree changing due to fatigue, this paper proposed a finite state machine based on PERCLOS algorithm and applied to pre-warning system of fatigue driving according to the original PERCLOS standards. Firstly, it used infrared camera to capture drivers' face in real time and detected face by ASM algorithm. To avoid the influence of the distance between man and camera, it normalized eye open degree when it was calculated. Then it obtained PERCLOS value by the proposed finite state machine based method. Finally, the eye open degree based system pre-warns the fatigue according to the established pre-warning mechanism. The experiment results show that this method can monitor drivers' fatigue status in real time and it is insensitive to light and drivers' accessories. [ABSTRACT FROM AUTHOR]

Lean management can eliminate wastage in work settings. Observational methods were adopted to determine the medical supplies in a Mobile e-Nursing Cart that had no fixed position, no clear indication, too many items, and no fixed quantity, resulting in wastage during work processes and inventory level difficulties. This management approach facilitates the reduction of wastage associated with e-Nursing Cart use, and has a goal of reducing the manpower wastage and inventory levels by 50% and achieving a work satisfaction level of 80%. Key solutions are developing related processes on medical supply items and quantities, designing boxes for medical supplies, and planning the placement of items. After the implementation of the evaluation, 91.6% of manpower wastage and 81% of inventory costs were reduced, resulting in a work satisfaction level with e-Nursing Cart use of 88%. Thus, this evaluation effectively reduces waste and enhances colleague satisfaction, and can provide a reference to reduce clinical burdens and costs. [ABSTRACT FROM AUTHOR]

Rapid progress in information and communication technologies and the increasing popularity of healthcare-related applications has increased interest in the topic of intelligent medical care. This topic emphasizes the use of information and communication technologies to collect and analyze a variety of data in order to provide physicians and other healthcare professionals with clinical decision support. At present, so-called smart hospitals are the focal point of most intelligent-systems development activity, with little attention currently being focused on long-term care needs. The present article discusses the application of intelligent systems in the field of long-term care, especially in community and home-based models of care. System-implementation components such as the data entry interface components of mobile devices, the data transmission and synchronization components between the mobile device and file server, the data presentation, and the statistics analysis components are also introduced. These components have been used to develop long-term care service-related applications, including home health nursing, home-care services, meals on wheels, and assistive devices rental. We believe that the findings will be useful for the promotion of innovative long-term care services as well as the improvement of healthcare quality and efficiency. [ABSTRACT FROM AUTHOR]

Many technology developments hold the potential to improve the quality of life of people and make life easier and more comfortable. New technologies have been well accepted by most people. Information sharing in particular is a major catalyst of change in our current technology-based society. Technology has widely innovated life and drastically changed lifestyles. The Technology Acceptance Model (TAM), a model developed to address the rapid advances in computer technology, is used to explain and predict user acceptance of new information technology. In the past, businesses have used the TAM as an assessment tool to predict user acceptance when introducing new technology products. They have also used external factors in the model to inluence user perceptions and beliefs and to ensure the successful spread of new technologies. Informatization plays a critical role in healthcare services. Due to the rapid aging of populations and upward trends in the incidence of chronic illness, requirements for long-term care have increased in both quality and quantity. Therefore, there has been an increased emphasis on integrating healthcare and information technology. However, most elderly are signiicantly less adept at technology use than the general population. Therefore, we reexamined the effect that the essential concepts in a TAM exerted on technology acceptance. In the present study, the technology acceptance experience with regard to telehealth of the elderly was used as an example to explain how the revised technology acceptance model (TAM 2) may be effectively applied to enhance the understanding of technology care among nurses. The results may serve as a reference for future research on healthcare-technology use in long-term care or in elderly populations. [ABSTRACT FROM AUTHOR]
