infants and postoperative patients. While air extraction and
droplet filtration systems are effective in containing these
viruses, interconnected ventilation ducts can still facilitate virus
transmission in areas with lower viral concentration. This study
introduces a Wireless Sensor Network based on WiFi
technology, designed to monitor crucial environmental variables
such as CO2, TVOC, temperature, and humidity, collectively
influencing indoor air quality. Moreover, this network connects
to an online server, collaborating with subscribers to store
historical data. The stored information aids in identifying
patterns and high-risk zones associated with the transmission of
respiratory diseases. The outcomes demonstrate a
comprehensive, adaptable, and scalable WiFi-based Indoor Air
Quality sensor network. Employing the publish-subscribe
pattern, the MQTT message transport protocol, and open-access
platforms like Streamlit, Supabase, and HiveMQ, along with
affordable boards and sensors, this solution offers an innovative,
scalable, and cost-effective approach to identifying areas at risk
of airborne disease transmission. The system's design prioritizes
data precision and reliability, making it a valuable addition to
indoor air quality monitoring systems.
Design of a model for the correct reporting of unproductive times in production lines
Authors: Reyes-Olán Claudia
Published: April 2024

The research carried out was conducted in a metalmechanical company, where there were reporting
problems from the operational staff, as well as
productivity indicators that did not allow for the reliable
analysis of the root cause of unproductive times,
preventing continuous improvement in the production
area. Therefore, a model had to be defined to prevent
certain events that affected productivity. The research
conducted was quantitative in nature since the hypotheses
proposed were tested through data collection, based on
numerical measurement and statistical analysis to
establish patterns of behavior and test theories. Data
collection focused primarily on the most frequently used
unproductive time codes according to the stipulations in
the quality management system. Additionally,
productivity calculations were made comparing deductive
codes with non-deductive ones to have a reference. The
collected data was analyzed using descriptive statistics to
obtain actions and reach the conclusion of the desired
model to implement in the production area.

Authors: Castillo-Quiñones Adriana Guadalupe
Published: April 2024

This paper was designed with the objective of describing
the characteristics and consequences of femicide in order
to raise awareness in society about the psychological
impact of its normalization and minimization. This crime
is due to the fact that the conduct itself develops within an
unequal power relationship between men and women, due
to different factors, among which can be found: economic,
political, social, religious and sexual, to mention a few.
Affecting not only the life and integrity of women, but also
third parties, such as the family. It is for this reason that
this paper seeks to provide a look at the effects that
femicide has on society, as well as the characteristics and
consequences of the same and some intervention strategies
that can be applied, giving importance to the psychological
area and the way in which, as a society we can contribute

Sizing of the photovoltaic system for a house located in the Presa la
Concepción subdivision in Santiago Cuautlalpan, State of Mexico
Authors: Hernández-Gómez Víctor Hugo
Published: April 2024

To cover the needs of the human being, either electrical or
thermal energy is used, which causes greenhouse gases
due to the origin of the energy, since most of it is generated
by burning fossil fuels. It is necessary to change the source
of energy for others that are not polluting, that is, for
renewable energies. In a house, energy consumption is in
electrical appliances, lighting, air conditioning,
entertainment equipment, stove and boyler. In a previous
study, strategies were proposed for the passive air
conditioning of a house in the Fraccionamiento de Presa la
Concepción located in Santiago Cuautlalpan, State of
Mexico, considering the bioclimate of the place. In the
present study, the photovoltaic system required to cover
the energy demand of that house is proposed. The
characteristics of the home are briefly described (location,
installed load and the bi-monthly consumption reported by
CFE), the methodology to be followed for the sizing of the
system and its application. A proposal of solar panels,
inverter and battery to be used with their respective costs
is given.
Burnout and health personnel in Morelos
Authors: Roque-Nieto Nohemí
Published: April 2024

This research aims to identify the existence of burnout
syndrome in a sample of 124 nurses from a health
organization in Morelos. The instruments used were the
Maslach Burnout Inventory (MBI) and a questionnaire to
measure the sociodemographic and employment profile of
the study subjects. We sought to measure the existence of
the syndrome in three subscales measured by the MBI:
emotional exhaustion, depersonalization, and personal
fulfillment at work, and relate them to sociodemographic
and occupational variables. A descriptive statistical study
and an inferential analysis were carried out using the
statistical package SPSS version 26. The main results
found were the following: Nurses present low levels of
burnout according to the results obtained in its three
dimensions: emotional exhaustion (9.62),
depersonalization (3.31) and personal fulfillment at work
(41.87). There are no significant differences between the
three dimensions of burnout and the sociodemographic
and occupational variables. Although the results indicate
low levels of Burnout, it is pertinent to replicate the
research in other groups of nurses susceptible to suffering
from the syndrome, as well as to carry out interventions,
providing them with strategies that allow them to face the
demands of their activity.
Commercial model to optimize supply chains in local markets
Authors: González-García Arcelia
Published: April 2024

Today, inventory management is a highly studied and
interesting topic to optimize the cost of managing them.
Traditional inventory models generally tend to block
inventory optimization, but the more the years have
passed, the concept of "supply chain" has been
implemented, where the satisfaction of the needs of the
final customer is achieved through material flows,
information and financial, which are established from the
original suppliers to the last consumer, requiring a certain
level of cooperation and integration between the
participants in the chain. That is why through the present
the design of a sustainable model to optimize supply
chains in local businesses in Jerez, Zacatecas is
investigated, proposed, and exposed.In this paper, the
optimization of inventories is studied, creating an effective
model that combines the traditional with the current and
that reflects the advantages of this approach in the total
inventory costs in the chain, that is, the optimization.

Authors: Saltos-Pineda Luis Manuel
Published: April 2024

The Internet of Things (IoT) in agriculture has contributed
to the efficient and effective automation of agricultural
production processes. However, automating irrigation is a
complex task due to the technological adoption challenges
faced by producers using unsustainable, inefficient, and
ineffective conventional methods, as well as the actions it
entails in the environment based on sensed data.
Therefore, as a proposed solution, the design of a CyberPhysical System (CPS) for automating irrigation in
ornamental horticultural production is presented. This
system follows a spiral methodology, allowing the
efficient construction of the prototype due to its iterative
and sequential capabilities. The result is the modeling of
the irrigation system based on a CPS, which will enhance
water usage efficiency, reduce labor efforts and production
costs, providing a mechanism for preventing and
controlling mite-type pests in ornamental horticultural
production.
Quality analysis of electrical energy
Authors: Nuñez-Gonzalez Dioni Victoria
Published: April 2024

This study exposes the measurements of electrical
parameters carried out with a power quality analyzer
in a transformer. The first measurement taking into
account a capacitor bank that was already installed
and then taking it out of operation. It presents the
results graphed in "Power Log" and analyzed with
respect to the standards CFE-L00045, IEEE 519-
1992 and the Regulatory Manual of Technical
Requirements for the Connection of Load Centers.
By disconnecting the capacitor bank, with the data
records obtained from the measurement, it is possible
to consider adding a harmonic filter that is presented
as the proposal for improving the quality of electrical
power, since it achieves an increase from 0.73 to 0.98
in the power factor without compromising the
permissible values of harmonics in the system. The
filter is calculated and simulated in "DigSILENT
Power Factory" to demonstrate the feasibility of the
proposal.

Trade-Embedded GHG Emission Transfer between South Korea and the EU

Purpose - The purpose of this study is to examine the implications of the Carbon Border Adjustment Mechanism (CBAM) for the transfer of greenhouse gas emissions (GHGs) through bilateral trade between Korea and the EU. Therefore, this study points out CBAM’s observable adverse effects from a consumption-based accounting perspective and suggests the proportion of the CBAM levy that should be refunded to Korea’s carbon reduction technology development fund as a way to address this. Design/Methodology – This study uses a multi-regional input-output (MRIO) model to analyze the extent to which industry-specific GHGs are transferred to each other due to bilateral trade between Korea and the EU. Then, using the emissions embodied in the bilateral trade (EEBT) model, we calculate the CBAM levy in Korea and the amount of funds that should be returned to carbon reduction technology development as an example. Findings – Our results show that Korea is a net exporter of GHGs to the EU’s final demand, and that the EU’s consumption-based GHGs are about twice as large as Korea’s when calculating each other’s consumption-based GHGs based on the industries covered by CBAM. In addition, we calculate the intensity-based shared responsibility of Korea and the EU for emissions exported from Korea to the EU to calculate the proportion of the CBAM levy that Korea should refund, and show an example. Originality/value – This study, unlike the existing literature on consumption-based emissions, calculates the transfer of GHGs from bilateral trade between Korea and the EU from the perspective of consumption-based accounting and provides implications for CBAM. It also argues that using the EU’s CBAM revenues to develop carbon reduction technologies in countries exporting to the EU could be more effective in reducing GHGs. Additionally, it emphasizes the need for the international monitoring of the EU’s CBAM revenues to ensure fairness and transparency.
