Bibliometric study for CO2 measurement using IoT: Looking for the Latin American contributions

2022 , Páez-Carabajo J.-D. , Huerta M.-K. , Rivas-Lalaleo D. , Vayas Ortega, Germania , Clotet-Martinez R. , Castillo-Velazquez J.-I.

In recent years, the number of deaths due to environmental pollution has increased. The main air pollutants are carbon monoxide, carbon dioxide, and sulfur dioxide. These are produced by the consumption of fossil fuels in vehicles, industrial activity, and agricultural practices, among others. Various technologies have been used to detect carbon dioxide (CO2), including the Internet of Things (IoT). However, no studies have been carried out to visualize the impact of IoT on CO2 monitoring and which countries are focused on minimizing emissions. This work shows a bibliometric study for CO2 environmental sensing using IoT. SCOPUS was the selected database, and PRISMA was the methodology used. The first search returned 13.207 documents written between 2013 and 2022, after filtering selected keywords, selecting only English articles, and abstract review we selected finally 79 documents for the measurement of CO2 using IoT. The results of analyzing them, show that the Asian countries produces more than the western countries, where India and Indonesia are leading. Also is interesting to note that the USA and Latin America produced the same quantity of documents, where the four countries contributing to Latin America are Brazil, Mexico, Peru, and Ecuador. The main area of knowledge covered by the documents was Engineering with 25 percent followed by computer sciences, and 40 percent of documents were published by IEEE. Finally, the Latin American contributions to this field are outlined, verifying in detail the architectures for the proposed solutions with emphasis in sensors. © 2022 IEEE.

Effect of the Real Wage on the Basic Family Basket in Ecuador

2024 , Vayas Ortega, Germania , Morales-Urrutia X. , Haro D.L. , Chancay D.

The effect of real wages on the basic family basket in Ecuador is a crucial issue in understanding households’ economic well-being. The real wage, which considers inflation and purchasing power, directly affects the ability of families to purchase essential goods and services. Analysis of this relationship provides insight into families’ challenges in meeting their basic needs and the potential implications for poverty and inequality in Ecuador. The study's objective is to analyze the purchasing power of the Ecuadorian population through data on real wages and basket costs from 2000 to 2021. The data analyzed comes from the Central Bank and INEC databases. The results indicate a sustained increase in the basic basket throughout the 2000–2021 period, which shows an increase in the prices of goods and services throughout the country. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

A long-range, low-cost technique to measure water level variations over limnimeters on hydraulic weir using machine vision and IoT

2022 , Chiliquinga-Chiliquinga A. , Garcés-Llerena R. , Bautista-Naranjo V. , Vayas Ortega, Germania , Castillo-Velazquez J.-I. , Clotet R. , Huerta M. , Rivas-Lalaleo D.

It is neither practical nor economical to make continuous and direct measurements of the water flow in a stream, so indirect methods must be used to measure the water level and, based on a calibration curve, relate it to the corresponding flow rate. A hydraulic weir with a limnimeter fulfills this purpose, but its disadvantage is that it does not allow the automated registration of the water level and therefore new and more efficient technologies must be used to perform this measurement automatically and thus have a lower waste and optimization of the resource. This experiment develops an algorithm based on computer vision and the inclusion of the concepts of the Internet of Things, in order to measure and record the values of the water level in a hydraulic dam, also includes energy storage system, power supply, remote computer, devices with wireless communication and IoT platform that allow a measurement error of less than ± 2% to be obtained with respect to a visual measurement made by the operator. © 2022 IEEE.

Human Capital and Per Capita Income in Ecuador

2024 , Vayas Ortega, Germania , Morales-Urrutia X. , Mesias J.P.M. , Yucsin K.

Human capital and per capita income are crucial in Ecuador’s economic development. Human capital, represented by the population’s education, health, and skills, directly influences the productivity and economic growth of the country. In turn, per capita income reflects citizens’ average income level and ability to access goods and services. The data analyzed comes from the World Bank database from 2000 to 2020. The main results indicate significant improvements in human capital due to various education and training strategies that different governments have applied. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

Factors for the Creation of Technological Startups in Latin America

2024 , Vayas Ortega, Germania , Morales-Urrutia X. , Naranjo-Santamaría J.

The changes produced in recent years have made innovation and technology play an important role in the growth of technological start-ups. Likewise, public policies have been developed that contribute to the development and strengthening of this business sector. The aim of the study is to analyze the incidence of institutional factors, education and innovation, in the generation of technological startups. The data analyzed comes from the Global Entrepreneurship Monitor, the Pearson Correlation statistical technique was applied. The results suggest that there is a direct relationship between the factors analyzed. In conclusion, the growth of this type of companies is still incipient in Latin American countries, however, there is significant growth of these in the region. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

Digital Marketing in the Tourism Sector of the City of Ambato

2023 , Suárez Pérez, Juan Carlos , Vayas Ortega, Germania

The research analyzes the digital marketing strategies applied by the tourism sector of the city of Ambato, as it is evident that, in the context of the pandemic and technological advances, companies were forced to digitize their businesses to be more competitive. By identifying the marketing strategies that are used in the sector, alternatives for improvement can be proposed, and counteract the effects of the pandemic. The methodology is of quantitative approach with a descriptive scope, non-experimental design which allows, through data collection and statistical analysis, to establish behavioral patterns and test theories. In this sense, the sector and the most used marketing strategies are identified and characterized. The results obtained conclude that Ambateño tourism companies do not have marketing departments that plan successful campaigns. In addition, it is observed that, for the most part, companies focus their efforts solely on social networks, especially Facebook, and do not take advantage of others that allow them to show more explicitly the attractions of a tourist destination and generate greater engagement. Therefore, it is proposed that tourism companies should digitize their businesses and rely on strategies that allow them to interact in real time with tourists without any restrictions. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
