Focused on the problem of current software remaining life prediction methods ignore the life information contained among multiple performance indicators, this paper proposed a remaining life prediction method of Web software system based on the Transformer model with multiple performance indicators(TransMP). Firstly, it constructed an accelerated aging experimental platform for a memory fault type Web system, and created a dataset containing performance indicators such as memory usage, response time, and throughput. Secondly, considering the differences in aging characteristic information contained in different performance indicators, it constructed the TransMP model consisting of multiple encoders-decoders. The performance indicator data was separately input into the memory indicator encoder, response time encoder, and throughput encoder to extract aging characteristic information, then it introduced a feature fusion layer for information fusion. Finally, it input the fused information into the decoder composed of a mask attention-multi-head attention structure to predict the remaining life when the system reached an aging threshold. The experimental results indicate that the remaining life prediction method of the Web system, compared to the SALSTM method, reduces the root mean square error by 12.0%, 17.3% and 13.2%, and decreases the mean absolute error by 13.3%, 21.0% and 10.4%, demonstrating the effectiveness of this method.

In the development of web systems, data uploading is a relatively important function. The traditional method of uploading data is to manually fill out forms, but when the data to be uploaded mostly exist in the form of form images, and the form content contains a lot of similar field information and irrelevant edge information, using traditional methods is not only time-consuming and labor-intensive, but also prone to errors. This requires a technology that can automatically fill in complex form images. OCR is an optical character recognition technology that can convert images into digitized text data using computer vision methods. However, using this technology alone cannot complete the tasks of extracting relevant data and filling corresponding fields. To address this issue, this article proposes a method that combines OCR technology and Levenshtein multi-text similarity. This method can effectively solve the problem of data filling after parsing complex form images, and the application results of this method in web systems show that the filling accuracy for complex form images can reach over 90%.

Background Currently, retail companies that fail to digitise their logistics processes experience difficulties in controlling stock, resulting in inaccuracies in the quantity of products and excess amounts in the warehouse. Consequently, the aim was to introduce a web-based system to enhance inventory control in retail firms within the city of Huaraz. Methods The Extreme Programming methodology was implemented in four phases. During the planning phase, roles and user stories were established. In the coding phase, Hypertext Preprocessor and JavaScript programming languages were utilised alongside the MySQL database management system. The testing phase involved evaluating each interface’s functionality to ensure that it was a part of the web system. The objective of this was to develop the web system and utilise it as an inventory control tool. Results The utilization of the web-based system within the logistics sector led to enhanced indicators, as seen through a 52.94% increase in inventory precision rate and 91.94% rise in the stock turnover rate. Conclusions The web system facilitates the minimisation of input errors in product quantity records while also enabling visualisation of such data. It further provides an illustrated representation, in the form of a bar graph, of each product’s indicator behaviour.

Background Nowadays, companies face continuous changes, which force them to be more versatile by managing large volumes of data, which do not always become relevant information for decision making. Therefore, the objective of this research is to implement a management information system to improve administrative management in micro and small businesses. Method it was developed under the approach of the agile methodology “SCRUM” following its 5 phases; In addition, the visual basic programming language in ASP.NET was used for the development of the source code and Microsoft SQL Server 2019 and its extensions: Ma-nagement Studio for data processing, “Integration Services” for the migration to the new dimensional model, Reporting Services for reports and Looker Studio for dashboards. Results The implementation of a management information system based on a dashboard allowed managers to obtain relevant information quickly and easily, optimizing decision-making times. In addition, the system allowed for homogeneous comparisons by level, which made it easier to identify deviations in commercial goals and the implementation of corrective actions such as adjustments in goals, changes in productivity, among others. Another result was the visualization of the monthly behavior of the financial system, which helped management structure short, medium and long-term strategies; in addition to the export of reports for “offline” analysis, which facilitates the work of employees in the field. Conclusions This allows reducing the time invested in generating reports, improving the efficiency and precision of the analysis. In addition, it has facilitated the identification of opportunities for improvement in administrative and commercial management, specifically in average productivity and the weighted average rate per advisor.

The workforce constitutes a fundamental element of organisations, and effectively addressing the challenges associated with governing employees is crucial for maintaining the overall stability of the firm. In the past, businesses and organisations used to depend on manual attendance tracking systems within their human resources departments to manage their staff. In the contemporary era characterised by significant advancements in technology, several recommendations are put out to enhance the existing system. Nevertheless, it is possible that small enterprises may encounter difficulties in coping with the escalating living expenses and the expenses associated with implementing an advanced attendance management system. Hence, this study proposes the creation of a straightforward yet dependable mobile application for the purpose of documenting and overseeing staff attendance through the utilisation of Flutter. The application was developed in a series of incremental steps utilising the Waterfall methodology. The effectiveness and acceptance of the application were evaluated using a comprehensive testing process that included both functionality and usability testing. Both testing findings yielded favourable outcomes, indicating that the application was favourably received by the responders. The application is anticipated to provide assistance to small enterprises or organisations that have encountered challenges in managing their operating expenses.

Contemporary small and medium enterprises, such as IT companies and legal, consulting, and logistic firms, use a variety of electronic tools for management purposes to provide their internal information exchange. However, there exist a number of problems (vacation registration, project reporting, professional literature issuance, etc.), which do not fit into the existing models of solutions. In similar cases, some IT companies create their own systems for the automation of homotypical procedures, but many firms have no software solutions for their automation. This paper presents the model and architecture of an open-code software for the staff appraisal service as one of the above mentioned unconventional problems. Such a system will enable the application of this flexible and simple solution at small and medium enterprises for frequently occurring management tasks. [ABSTRACT FROM AUTHOR]

In order to detect potato crop pests from symptom images, a web platform was developed to facilitate the diagnosis of early and late blight from images of affected leaves. The Python programming language, the Flask framework, Bootstrap for platform styling, the necessary libraries, and Pycharm as development environment were used. Image recognition and artificial intelligence software tools, specifically artificial neural networks, were used to implement the diagnostic module. The system also includes the field monitoring record with the incidences of pests, allows incorporating new data, and provides information on management in correspondence with climate variability. For the diagnosis validation, images of symptoms confirmed by experts were taken. The neural network model used was 94.6 % accurate. Future work will include the detection of viruses, bacteria and other fungi from images. The tool is a useful and novel application at the service of agri-food safety, serving as a coordinated platform for plant protection technicians and farmers involved in potato cultivation.

People explore specific services or information to accomplish their goals within a web system. Efficient visitors' exploration routes must be defined as requirements to guide them through a good experience. In order to define these requirements, we focused on links from one object to another and developed a method named Traverser to guide the visitors from the starting point to the destination. In our study, these links are within the ontology of a service domain. The set of links to guide visitors from a certain object to the destination is referred to as a "traverse." A traverse is inferred from the ontology by tracing associations and inheritance relationships between domain items, taking the rights of each user group into account. The ontology for extracting traverses is developed as a conceptual model with a class diagram of UML, while the roles of an association are diverted as a user group's permissions. We also developed a tool to define the conceptual model and extract traverses. The effectiveness of Traverser is evaluated by comparing the requirements derived by Traverser with those of the use case approach. [ABSTRACT FROM AUTHOR]

The increasing amount of data from web systems data is becoming one of the most valuable resources for information retrieval and knowledge discovery. The huge content of information makes it an important area for data mining research. To analyze the dependencies of the outcoming data, expressed as query scenarios, we present a new approach for evaluating the behavior of interactive web systems by applying different data mining techniques to solve the problem. We propose tools that take outcoming logs as input, analyze them, and provide information about web client actions. Qualitative and quantitative automatic evaluation of the data can explain the connections between the most significant parameters of the system in particular scenarios. In this paper, we propose a new method, which can be used to efficiently verify the type of client behavior of a web system or design of the system. The analysis of results demonstrates the possibility of efficient pattern search. [ABSTRACT FROM AUTHOR]

Natural disasters, such as tsunami, claim lives of many coastal residents every year. Therefore, tsunami evacuation drills are important for costal residents to survive tsunami. We developed a tsunami evacuation drill system that enables participants to evacuate and move to a shelter while occasionally glancing at a map-based tsunami simulation on mobile devices. The system has the following advantages: (1) a practitioner can easily customise the simulation, (2) the simulation can be displayed on a web browser and (3) the participants' evacuation routes can be recorded and displayed on the simulation system. We conducted a preliminary comparative experiment with 18 university students and found that the developed system was accepted more by participants using a tablet rather than by those using smartglasses.

To identify the needs of modern recruiting and determine the features of staff selection and evaluation using psychological testing, was conducted an analysis of existing developments and systems that are used in the modern recruitment process. The problems that HR managers have when testing a candidate and the company's staff are identified, and the disadvantages of modern recruiting systems are highlighted. According to the detailed structure of the personality and the structure of the psychological portrait, the main features of the candidate's personality were identified and selected methods that can be used for testing. A web-based system "KnitTe" for HR managers was developed, which allows clients to expand the functionality of their CRM systems (initial stage integration with Odoo CRM modules) and helps in making a decision about the suitability of a candidate for a specific position in terms of their psychological personality traits, as well as their psychological compatibility with other team members. The overall structure of the web system allows the client to get data from the CRM system, use built-in psychological tests, and get results. The "KnitTe" web-system uses reliable, valid and verified psychological methods, builds a psychological portrait of the candidate, checks the candidate's compliance with the chosen position, and analyzes the candidate's compatibility with the team.

This paper presents the development of a web platform for the prevention and attention of cases of cyberbullying against Children and Adolescents, who currently due to the confinement by the COVID19 pandemic, are in greater contact with digital media. According to international and national statistics (in Mexico), children and adolescents are hyperconnected, with little supervision in the use of media and with out guidance in the safe and responsible use of technology. They are learning from home and school classrooms are now on digital media, so elementary, middle and high school students are not exempt from being victims of attacks such as cyberbullyng, sextortions, phishing and grooming, among others, which unfortunately affect their physical and psychological integrity. In coordination with an agency responsible for the protection of the rights of children and adolescents (the System for the Comprehensive Protection of Children and Adolescents of a local government), we worked on the analysis, design, development and testing of a platform that allows, mainly three things: 1) inform and prevent through digital content about online risks; 2) diagnose the vulnerability of children and adolescents to make decisions and implement targeted actions in schools where there is greater vulnerability; and finally, provide a reporting mechanism, through which children and adolescents can report to SIPINNA if they are victims of any type of cyberbullying and the organization can address or channel with the pertinent authorities.

The growth in biomedical data resources has raised potential privacy concerns and risks of genetic information leakage. For instance, exome sequencing aids clinical decisions by comparing data through web services, but it requires significant trust between users and providers. To alleviate privacy concerns, the most commonly used strategy is to anonymize sensitive data. Unfortunately, studies have shown that anonymization is insufficient to protect against reidentification attacks. Recently, privacy-preserving technologies have been applied to preserve application utility while protecting the privacy of biomedical data. We present the PICOTEES framework, a privacy-preserving online service of phenotype exploration for genetic-diagnostic variants (https://birthdefectlab.cn:3000/). PICOTEES enables privacy-preserving queries of the phenotype spectrum for a single variant by utilizing trusted execution environment technology, which can protect the privacy of the user's query information, backend models, and data, as well as the final results. We demonstrate the utility and performance of PICOTEES by exploring a bioinformatics dataset. The dataset is from a cohort containing 20,909 genetic testing patients with 3,152,508 variants from the Children's Hospital of Fudan University in China, dominated by the Chinese Han population (>99.9%). Our query results yield a large number of unreported diagnostic variants and previously reported pathogenicity., Competing Interests: Conflict of interest We declare that the authors have no conflict of interest that might be perceived to influence the results and/or discussion reported in this paper., (Copyright © 2023 The Authors.

Mobile learning (m‐learning) refers to knowledge and abilities acquisition through the use of mobile technology anywhere at any time. Mobile learning objects (MLOs) are key elements for this teaching paradigm; several software tools have been proposed to support the construction of MLOs; however, they do not take into account pedagogical and technological aspects simultaneously during the construction cycle of MLOs. This paper presents the analysis, design, and development of a web system called SiGOAM, which supports specialized services to professors to generate quality MLOs. These services follow a formal MLO's construction cycle integrated into four phases: analysis, design, development, and product‐oriented assessment. As a result of this formal approach, the proposed system generates quality MLOs that are embedded in mobile devices and accessed through web browsers. We performed a usability assessment of our system SiGOAM based on a field study. The results show that professors assigned acceptable values for effectiveness, efficiency, and satisfaction.
