In the manufacturing sector, the Lean philosophy is well known for propos-ing the reduction of waste within the industry, which is manifested in terms of downtime within companies. In a sector of large proportions such as mass consumption food, the reduction of these losses translates into significant savings in the business economy, so key indicators, such as the OEE, are used to evaluate the efficiency of the process in terms of quality, perfor-mance and availability. Within this context, this article presents an applica-tion model of Total Productive Maintenance (TPM), using FMEA for the di-agnosis and SMED for the optimization of the results, within its structure; which was validated through a pilot test, achieving an increase of 5.17% in the OEE of the sauce production line of the company in the case study, demonstrating the effectiveness of the model within contexts whose losses lie in prolonged machine downtime.

During the last decade, SMEs of bakery products in Peru have presented high production costs due to the empiricism in carrying out activities generating times that do not add value to the process, which directly influence low productivity. Furthermore, this sector has potential growth that must be exploited using innovative methods to achieve greater competitiveness. Furthermore, there is little evidence in the scenario of bakery SMEs that seek to reduce travel times in the process and improve methods in the production area. This article presents a model that integrates the SLP methodology and work study with the aim of increasing productivity in a bakery SME by optimizing the resources used and generating significant cost savings. The model was validated in a Peruvian bakery, where productivity was improved from 1.22 to 1.45.

Playgrounds were also closed off to prevent children from having close contacts with others to prevent the spread of the COVID-19 pandemic. Field visits were carried out to investigate the situation. It was found that many play facilities were closed off by using barrier tapes and barricades, and some children and their caregivers still played in the playground. However, the management company and policy-makers were unable to respond to children’s and caregivers’ needs. The paper thus suggests a user-management-policy (UMP) model illustrating the ideal communication and collaboration among user, management company and policy-makers in an existing facility.

In this research, we will focus on INSOTEC NGO, an entity dedicated to granting microcredits to entrepreneurs with limited economic resources. This company is present in rural areas of Ecuador, increasing its income in recent years. The organization plans to become a bank in the long term and expand its operations to near countries such as Colombia and Peru. However, the entity's customer classification processes have had many drawbacks because it is currently a manual procedure that generates a high operational burden, slow response times to customers, huge inefficiency rates, and a great problem to continue growing. This project proposes to model an artificial intelligence algorithm that classifies the organization's clients based on the different variables that are considered convenient for the analysis. The method selected to meet this objective is a Random Forest, a supervised learning method that builds models that are easy to interpret. Its implementation complexity is very low, it allows continuous and categorical values, and it handles noise from data from different sources very well. This new process will guide the organization to implement these models in other areas such as risk, finance, auditing, and operations.

In the high Andean areas of Junín in Peru, maca (a tuber typical of Peru) and maca flour are produced. At the end of the harvest, farmers have the hard work of removing the root and stalks of the remaining maca. Faced with this problem, the "stalk cutting and maca sorting machine" was designed, a ma-chine proposed when analyzing the difficulty of cleaning the maca after har-vest, then it must be dried and processed. This proposed machine will save time and increase production. In the traditional way (manual), farmers clean 4 kg of maca in 2 to 3 minutes, however, with the proposed machine 6.67 kg of maca will be cleaned in 3 minutes. In addition, a heat treatment will be developed on the copper surface that will have contact with the tuber, for the elimination of bacteria and viruses such as COVID-19.

This research presents the proposal for a low-cost digital spirometer called “Phukuy” that includes the following sensors: an oximeter that measures the percentage of oxygenation of the blood (SpO2) and the heart rate (bpm), a body and environmental thermometer, and a barometer. This spirometer will serve for the diagnosis and remote monitoring of people with Chronic Obstructive Pulmonary Diseases (COPD) including COVID; benefiting people who do not have a nearby health center; This will help decongest hospitals and prevent them from becoming an infectious source. In addition, all the information obtained from the measurements will be saved on a web platform, which can be accessed by a designated doctor. The proposed spirometer was validated with a 3-liter calibration syringe, obtaining an average error of 0.033 L (1.1%) and a maximum error of 0.070 L (2.33%), which is within the range recommended by SEPAR (± 3 %).

The main objectives of this work are to create a platform for cross-disciplinary dialogues that integrate different knowledge and research from diverse sectoral, geographical, and institutional perspectives, in particular, to implement international experience and improve the socio-cultural develop-ment level of Ukraine. The peculiarities of the development of Ukraine’s tourism industry have been compared. Its place in the world market has been determined by the main socio-economic indicators. Tourism development should be an object of cultural and historical heritage.

Nowadays, online route planners for soft modes are provided by several platforms such as Google Maps, OpenStreetMap, Here, or Waze. Itineraries are usually built using Shortest Path Problem algorithms that minimize travel time or distance. In this work, we aim to identify and quantify the main features that influence itineraries’ choice by soft modes users in urban areas, able to support multi-objective routing, using simulated scenarios. We propose a set of 21 indicators, grouped into five dimensions: Safety-Security, Comfort, Air Quality, Accessibility, and Time-Distance. Another contribution of this work is the simulation of scenarios to study soft modes’ multi-objective routing within urban areas.

The use of online social networks is giving rise to a line of research focused on the phenomenon of addiction that occurs due to the intense use of technologies and the Internet. The objective of the study was to determine the relationship between the use of virtual social networks and social skills in university students from northern Peru. The design was non-experimental, cross-sectional, correlational. A survey was applied as a technique and the instruments were two questionnaires, the Test of addiction to the use of social networks-ARS and a Test scale of social skills-EHS. It was found that 71.7% of students showed a low level of obsession with the use of virtual social networks, 27.2% medium level, while 1.1% high level. Concluding that addiction to social networks has a significant relationship with social skills; that is, the greater the use of social networks, the greater the development of social skills.

Triggering emotions in a driving simulator is not easy as the virtual environment reduces the reality of the situations. This contribution deals with the induction of emotions in drivers during the simulation and addresses the possible hindrances in the design and implementation phases. For this purpose, an experiment is conducted on a driving simulator with 20 participants, 5 females and 15 males, aged 22 to 30 years old. First, important emotions that may recur in driving situations are presented. Then, the process of evoking emotions in drivers is clarified, three different strategies, namely monotonous, event-driven, and combination, are described, and the intensity of emotion evoked by each modality of the stimuli is examined. In addition, a mapping from three-dimensional to discrete emotion space including seven states is presented. Finally, to evaluate the concepts discussed, the results regarding driver emotion and scenario validation are presented and general recommendations are provided.
