In the university educational processes, one of the final processes is the completion of professional internships, which allow the student to carry out activities specific to his/her specialty. At the end of the procedure, a report is sent which is evaluated by 3 professors. The evaluations are mostly carried out qualitatively, which does not allow a final result for the student. The present research is carried out in order to analyze the qualitative results and transform them into a quantitative value, related to the approval or disapproval of the report, for which the fuzzy logic technique is used, with which we obtain a final grade. The proposal also includes a web system that can support the processes of student registration, entry of documents and final results, in such a way that they can be accessed without having to be on the university campus. The documentary processing processes are based on the ISO 25000 standard that ensures compliance with the standards of the University and the degrees and titles office, which is in charge of issuing conformity in the completion of professional internships. The proposal can be replicated and scaled to other processes related to the use of fuzzy logic.
Managing smart city infrastructures in
multi-tenant environments presents challenges in
identifying problems and dysfunctions, as well as in integrating data and services accessible to
different stakeholders. A unified knowledge model was proposed that allows smart city operators
to manage and analyze data more efficiently, facilitating scenario creation and informed decision
making, using data analytics processes, microservices, "what-if" analysis tools, and data storage to
integrate contextual information on traffic, weather, and air quality, as well as critical events,
achieving better traffic prediction and management, allowing operators to suggest alternative
routes and act on road restrictions in real time. In addition, the communication of alerts and
changes was improved through mobile applications and variable message boards; concluding that
the proposed model improves the scalability and maintainability of smart city infrastructures,
allowing more effective collaboration between different entities and optimizing the use of
resources. This lays the foundation for the development of smarter and more reactive applications
in the urban context [

lifestyles and support informed decision making in urban planning and resource allocation [
The need to validate smart city interfaces from a user-centered design perspective, comparing low
and high fidelity prototypes in physical and virtual reality environments, for which low fidelity
physical prototype field tests and high fidelity tests in virtual reality environments were compared
to evaluate realism, interactivity, presence and task difficulty, through the implementation of low
and high fidelity prototypes, qualitative interviews and presence and interactivity analysis tools
were used, involving design students and experts to obtain insights, resulting in that virtual reality
improves visual realism and discussion of user flows, although it has limitations to replicate
realistic interactions and social contexts, compared to field tests, concluding that virtual reality is
useful in the design process to visualize procedures and test complex user flows, but must be
complemented with field tests to capture the context and real user interaction [

In this work, we developed a method to evaluate pre-professional internship reports in a public university in Peru, where evaluations are often carried out in a qualitative manner, such as good, average or low, which makes it difficult to determine whether the report is approved. We developed the traditional evaluation method through a web system and how this can also be complemented with the use of the Fuzzi Logic model, which allows us to evaluate whether the student passed their pre-professional internship report.
Pre-professional internships are an essential component of the training of students at public universities in Peru, who begin their insertion into the labor market for a specific period of time, thus building a bridge between theory and practice, between the training stage and entry into the labor market. In this sense, pre-professional internships are a critical aspect for students at public universities, since they allow them to acquire work experience in their area of study and establish important contacts in the working world. In the public university, where there are a large number of students and companies involved in this process, the management of pre-professional internships can be complex. When implementing a web-based system to manage the preprofessional internship process, a series of challenges and problems arise that hinder its effective implementation and proper use.
Consequently, if we consider that public universities in the Lima region have a varied student population between the ten semesters of study, it is estimated that everyone at some point will take the pre-professional internship course, since this course is included between the ninth and tenth cycle of the study plan and the school management must be prepared to be able to generate a process in the most perfect way possible. In this sense, we should mention that for different reasons the professional schools do not have a system that automates the management process of pre-professional practices, which is why it becomes an object of study in this thesis. The materials and methods are described by the presentation of the processes necessary to be able to replicate the methodology.
The description of the problematic reality is described in the conditions that are needed to be able to start and to be able to conclude the pre-professional practices processes. We begin by indicating that the pre-professional practices are an indispensable requirement to be able to obtain the bachelor's degree for the students, which is why there is a need for the students to be able to pass this evaluation, which consists of the review of the practice report that the student made and that must be approved.
The mechanism of review and approval of the practice report consists of the detailed review of the report by three teachers, each of them evaluates the report and according to their recommendations, the report is approved or disapproved. The report is sent to 3 teachers, after the student registers in the Web System for the exclusive use of students and the degree and title office.
Below we present the main processes of the pre-professional internship system:
The management of pre-professional practices encompasses the development, programming, coordination, control and assessment of internship plans, with the purpose of ensuring an adequate education for students and an effective connection with the work environment.
Pre-professional internship management involves the planning, coordination and evaluation of practical learning opportunities for students, in order to combine theory and practice, boost the development of skills and competencies, and facilitate the transition to employment.
The selection process comprises a series of organized and consecutive stages that are carried out for the purpose of collecting data on candidates, analyzing their capabilities and competencies, and making informed decisions about their suitability for a given position. The selection process encompasses a set of methods and tools used to recognize and assess suitable candidates, with the goal of determining who will be hired to fill a position, thereby ensuring a fair and unbiased selection.
Refers to the number of students who are carrying out internships in an organization or company as part of their academic or pre-professional training. These numbers may vary depending on the context and policies of the university and the organization receiving the internship.
Refers to the percentage of students who are carrying out internships in an organization or company as part of their academic or pre-professional training. These percentages may vary depending on the context and policies of the university and the organization receiving the internship.
Supervision encompasses the act of observing, guiding, and leading the work of subordinates for the purpose of ensuring that established objectives are achieved and required performance standards are met.
Refers to the number of times a supervisor visits or inspects the internship center to monitor and evaluate its performance. These supervisory visits are part of a monitoring and follow-up process designed to ensure that quality standards, established objectives, and university policies and procedures are being met.
Communication refers to the process by which information and meaning are transferred and exchanged between two or more individuals, for the purpose of sharing knowledge, ideas, feelings, and coordinating actions effectively. Communication involves conveying information, ideas, emotions, and meanings using both verbal and nonverbal symbols for the purpose of exerting influence on other people's thinking and behavior.
Refers to the number of students who recommend to other students to carry out an internship in an organization or company as part of their academic or pre-professional training. These numbers may vary depending on the context and policies of the university and the organization receiving the internship.
The description of the methodology is related to the description of the tools used to implement the web system and the intelligent part, which consists of working through fuzzy logic, for which the Matlab tool has been used. Below we describe the architecture of the application.
Figure 2 presents the architecture of the implemented solution; for the implementation of the web system, where the use of the PHP programming language in version 8 with Laravel in version 9.19 is used, the chosen database is MySQL and as the HTTP client Guzzle for PHP, the intelligent component is developed in Matlab using the Fuzzi Logic tool. In Figure 3, the evaluation mode of the practice reports is presented, the process begins with the sending of the report to three teachers, each one evaluates according to their perception and experience, the result of the evaluation is a grade that in many cases is a qualitative grade, which can have the values of "High", "medium" or "Low", which makes it difficult to obtain the final result of the evaluation that is approved or failed; For this task, we resort to the use of the intelligent component that is the use of fuzzy logic, for which the values of the teachers' grades are evaluated, and the final evaluation value is returned.
In Figure 4, the pseudocode of the intelligent component is presented, where it is described how the web system and the Matlab tool work, in order to have the final result of the evaluation, this process is carried out manually, as a demonstration mode, where the evaluation value of each teacher is taken, loading it into the Matlab application and the result is loaded into the web system, with which the process is closed, with the final evaluation values which are "Passed" or "Failed".
The uses and applications are related to the way of using the implemented web system, where the intelligent component that performs the calculation of the evaluation of the partial results stands out; in the implemented test model the process is carried out manually, with the intention of being able to carry it out automatically by presenting a function that converses the Matlab function with PHP.
The results we describe are related to being able to describe how the web system and the intelligent component work, analyzing the main processes of the system, such as the student registration process and the evaluation with the Matlab tool.
In Figure 5, the registration screen of the proposed system is presented, where the entry is evidenced through a user registration, having to enter with its corresponding password.
Figure 6 shows the main form for data entry by students. The data entered includes the specialty that the student is studying, the place where he/she did his/her internship, and most importantly, the entry of the report made, where the information on the internship process is found.
When quantitative results are obtained, evaluation is carried out using Fuzzi Logic techniques, with which a report is evaluated by 3 teachers, so its result must be approved and disapproved, the evaluators' review values are "good", "regular", and "bad". Below we present the generated model, considering an output with "approved" and "failed" values.
In Figure 7, the fuzzy logic model is presented where there are 3 inputs that correspond to the evaluators and an output that corresponds to the result of the evaluation.
In Figure 9, the interpretation of the rules is presented, considering a value of bad ensures disapproval, and a minimum approval value is when the 3 evaluators consider it as regular, higher combinations ensure approval of the report.
Figure 10 shows the 3D model, where the minimum approval values are evident; values greater than 0.5, which corresponds to the "regular" value of the evaluation, ensure approval and lower values are considered as failure.
In conclusion, with the use of fuzzy logic, embedded in a web application, an increase from 40.52% to 82.76% was achieved, which allowed validating that the use of fuzzy logic, implemented in a web system, is favorable for the indicator number of practicing students.
It is concluded that for the indicator number of supervised visits to the pre-professional internship center there was an increase of visits to the pre-professional internship centers by the preprofessional internship supervisors quite considerable equivalent to 42.24% since at the beginning the supervised visits were on average 40.52% per semester and after the implementation of the software the sales were on average 82.76%.
It is concluded that the indicators number of students practicing and the number of supervised visits to the center of pre-professional practices allow a favorable measurement for the management of pre-professional practices validating that these are concluded in a correct way and that they increase in quantity and therefore there will be more graduates for the university. It is recommended to optimize the internship computer system by developing a new project solution following the MVC (Model View Controller View) software architecture pattern that will help to separate the data and business logic of the internship system, thus facilitating maintenance, component reuse and scalability of the application.
It is also recommended to improve the organization of the employability workshops to be more precise the workshop of Induction of pre-professional practices, it could be considered the use of the google calendar for the scheduling of the workshops mentioned on the website and other media that the Communications office uses for the dissemination of our event thus informing students the schedule of the workshops in a timely manner for their registration and participation. It is recommended to continue conducting periodic studies on the satisfaction of students who are doing internships, since in many surveys the suggestions presented by the students show which changes or problems are the most critical in order to address them in a timely manner, even more so if they are related to the internship computer system.
Finally, it is also recommended to make an evaluation about the programming language to be used in a future new version of the internship computer system, since the public universities can use the reculate framework for the projects that are developed in the corporation can also adopt the Python programming language that has additional advantages to the language used in the present pre-professional internship system (PHP) since most of the web applications used in the corporation and also in the development industries that use Python with R.
When evaluators provide qualitative values, we resort to the use of evaluation tools using the fuzzy logic technique, resulting in a result that can be worked on, as is the case with the evaluation of reports, where a report result is required, for which the fuzzy logic technique is very helpful.
