Academic failure is a situation that influences the terminal efficiency of students at a higher level. This is a consequence of various factors that affect the student. The objective is to identify factors that influence school failure in the face of the pandemic. A data collection model was applied for the analysis of factors that influence school failure based on the student's perception during the second year of the pandemic. The model considers technological, academic, and personal factors; The figure of the manager and the academic tutor are incorporated as elements that can influence school failure. The instrument was applied online, and data analysis and reliability were performed with free software tools. The age range of the participants is 18 to 25 years old. 53.1% of the participants consider that the absence of a tutor in the face of failure problems influences failure. The factors that influence failure are the academic tutor, academic manager, internet access, the delivery of projects, the teacher's way of explaining, and health. The tutor and the academic manager have an important role as a guide in a situation of failure or academic performance. [ABSTRACT FROM AUTHOR]

Smart Education is the influence of diverse technologies (Combinatorial Optimization, Machine Learning, Big Data, data visualisation, Internet of Education Things, Learning analytics, and others) to enhance the quality of education. In other words, Smart Education is the process of optimally managing human, economic and technological resources from educational institutions and research centres. Smart Education is part of the Smart Society (a component of a Smart City). The Smart Education components are the Internet of Education Things (Wireless Sensor Networks, RFID Technology), management of the education physical, infrastructure, smart classroom, smart campus, smart learning, Learning analytics, Smart Analysis, data science, Education Impact, and Educational Policy. This paper is a guide for understanding Smart Education components by presenting a survey of the characteristics, taxonomy (Education-Hard problems and Education-Soft problems), smart education indicators, history and future trends.

High levels of consumption of electrical and electronic equipment, together with the decline of their useful time of life (obsolescence), has led to a progressive growth in the generation of Waste Electrical and Electronic Equipment (WEEE), also known as e-waste. The problems involving inadequate management of these are reflected mainly in the negative impact on the environment, but it also entails a waste of opportunities for reuse of components that can still generate value. This article presents a review of the literature on the studies that address the appropriate process of recovery of WEEE, i.e., the process of Reverse Logistics, and identifies the trends of study on the subject and proposed new lines of research in the management of the WEEE.

The Vehicle Routing Problem (VRP) consists of minimizing the cost of transferring resources, goods or people. There are different variants of the land transport problem, among the main ones are the location of bus terminal, convoy routing, inventory routing with time windows, school bus routing, travel planning problem, among others. The problem of vehicle routes with time windows (VRPTW) is to minimize transport costs considering restrictions in the delivery time. In this work, articles from scientific journals referring to the solution of terrestrial transport problems were reviewed, specifically, the works that develop heuristic algorithms. The objective of this work is to obtain a frame of reference for the works that apply meta-heuristics to the solution of the problem of land transport of perishable products. The result of the work is a framework that shows state of the art in the solution of VRP of perishable products and outlines the future work for the investigation based on the existing gap in this subject.

The Project Scheduling Problem (PSP) is a generic name given to a whole class of problems in which the best form, time, resources and costs for project scheduling are necessary. The PSP is an application area related to the project management. This paper aims at being a guide to understand PSP by presenting a survey of the general parameters of PSP: the Resources (those elements that realize the activities of a project), and the Activities (set of operations or own tasks of a person or organization); the mathematical models of the main variants of PSP and the algorithms used to solve the variants of the PSP. The project scheduling is an important task in project management. This paper contains mathematical models, resources, activities, and algorithms of project scheduling problems. The project scheduling problem has attracted researchers of the automotive industry, steel manufacturer, medical research, pharmaceutical research, telecommunication, industry, aviation industry, development of the software, manufacturing management, innovation and technology management, construction industry, government project management, financial services, machine scheduling, transportation management, and others. The project managers need to finish a project with the minimum cost and the maximum quality. [ABSTRACT FROM AUTHOR]

This paper aims to guide understanding of the different types of optimization problems of water distribution networks by presenting a survey of mathematical models and algorithms used to solve the variants of said networks. Problems include water resource planning, water quality management, water supply networks, water distribution systems, water flow and chemical transport, and water distribution network. Optimizing resources to transport water is an issue of global interest and is important to minimize the costs of construction of pipeline to supply water, repair costs, and water transportation.

The small and medium-sized enterprises are the main nucleus, which moves the economies of countries such as Mexico. Many of them have emerged by need lack of sources of employment, attending to the needs in an empirical manner; identifying here an area of opportunity for IT professionals. We can provide the tools for anyone involved with SMES, to improve the productivity and competitiveness of the business. Therefore, the purpose of this paper is to present the desirable characteristics that must contain the software repositories for SMBS, and an assessment of state show that SMES.
