This research presents a 100% renewable energy (RE) scenario by 2050 with a high share of electric vehicles on the grid (V2G) developed in Ecuador with the support of the EnergyPLAN analysis tool. Hour-by-hour data iterations were performed to determine solutions among various features, including energy storage, V2G connections that spanned the distribution system, and long-term evaluation. The high participation in V2G connections keeps the electrical system available; meanwhile, the high proportions of variable renewable energy are the pillar of the joint electrical system. The layout of the sustainable mobility scenario and the high V2G participation maintain the balance of the electrical system during most of the day, simplifying the storage equipment requirements. Consequently, the influence of V2G systems on storage is a significant result that must be considered in the energy transition that Ecuador is developing in the long term. The stored electricity will not only serve as storage for future grid use. Additionally, the V2G batteries serve as a buffer between generation from diversified renewable sources and the end-use stage.

Food safety has gained great importance in recent years. Food marketing has significantly influenced the eating habits of our society, which proves the importance of real-time and authentic communication. As a result of it, an urgent need has arisen in the food industry to find substitutes for additives that can potentially cause toxic or allergic reactions in humans. In addition, the so-called “functional foods” have introduced new trends in the demand and production of foods. One such trend has been the substitution of artificial colorants with beta-carotene – a natural colorant with a strong pigmenting power. However, many countries including Ecuador have still not been able to exploit this colorant at industrial levels as a total substitute for artificial colorants. Therefore, this analytical study concludes that an assertive communication is relevant for the industry, as investigated in this practical case. Keywords: communication, food industry, beta-carotene, economic impact. RESUMEN La seguridad alimenticia en los últimos años ha marcado gran importancia dentro de esta industria, el marketing ha influenciado notablemente en el estilo alimenticio de la sociedad, la comunicación real y adecuada en el momento exacto es lo que hace falta y de ahí nace la necesidad de encontrar sustitutos para algunos aditivos que han sido potencialmente tóxicos o alérgenos en el ser humano, sumado a esto que los alimentos funcionales marcan nuevas tendencias de demanda y producción, entre ellos los que tienen propiedades antioxidantes como es el caso del betacaroteno, un colorante natural que posee un notorio poder pigméntate que sin embargo no ha podido ser explotado a niveles industriales como sustituto total de colorantes artificiales, en diferentes partes del mundo incluido Ecuador, la presente investigación se realiza de forma analítica, concluyendo que es relevante una asertiva comunicación para la industria como lo investigado dentro de este caso práctico. Palabras Clave: comunicación, industria alimentaria, beta-caroteno, impacto económico.

For UNUH campus hybrid use of solid fuel and gas boilers was carried out. Decentralization of the university heating system has been conducted through the restoration of 350 individual heating systems in residential buildings, remote departments and campus dormitories. The conclusions propose the list of activities upon the real economy of fuel and energy resources, and measures to overcome the economic and political crisis in the country.

Although traditional agriculture carried out by ethnic groups is considered for its high biodiversity and important for food security and sovereignty, few studies have investigated the potential of these systems in the interest of promoting a sustainable agricultural development policy according to United Nations Sustainable Development Goals. Using the FAO's Sustainability Assessment of Food and Agriculture (SAFA) methodology, this study analyzed the sustainability of four traditional agricultural systems, three indigenous (Waorani, Shuar, and Kichwa) and one migrant settler populations in the Yasuní Biosphere Reserve (YBR) and identified synergies and trade-offs among the dimensions of sustainability. The results showed different dynamics in all dimensions of sustainability-specifically, trade-offs in the dimensions of good governance with environmental integrity and social well-being, economic resilience, and social well-being. It was identified that the differences in terms of sustainability are narrowing between the indigenous Shuar people's traditional agricultural systems and those of migrant settlers, which provides policymakers with specific information to design sustainable development policies and rescue traditional agricultural systems in the Amazon region.

Abstract This paper proposes a framework to estimate the effects of exogenous fiscal policy and oil revenue shocks on the macroeconomic activity of price-taking oil producers. We use a structural vector autoregressive model estimated with Bayesian methods and apply it to the Ecuadorian economy. Specifically, we investigate the effects of unanticipated changes in taxes, government consumption spending, government investment spending, and oil revenues on economic activity. The results show that unanticipated expansive fiscal policy either through taxes or government investment can have positive effects on output. However, contrary to most studies in the literature, consumption spending shocks do not significantly affect gross domestic product. We also find that oil revenue shocks influence all the variables in the model, evidencing the vulnerability of the Ecuadorian economy to fluctuations of oil revenues. Historically, oil revenue shocks have been the most important driving force to move output above or below trend.

The present work is a survey on aircraft hybrid electric propulsion (HEP) that aims to present state-of-the-art technologies and future tendencies in the following areas: air transport market, hybrid demonstrators, HEP topologies applications, aircraft design, electrical systems for aircraft, energy storage, aircraft internal combustion engines, and management and control strategies. Several changes on aircraft propulsion will occur in the next 30 years, following the aircraft market demand and environmental regulations. Two commercial areas are in evolution, electrical urban air mobility (UAM) and hybrid-electric regional aircraft. The first one is expected to come into service in the next 10 years with small devices. The last one will gradually come into service, starting with small aircraft according to developments in energy storage, fuel cells, aircraft design and hybrid architectures integration. All-electric architecture seems to be more adapted to UAM. Turbo-electric hybrid architecture combined with distributed propulsion and boundary layer ingestion seems to have more success for regional aircraft, attaining environmental goals for 2030 and 2050. Computational models supported by powerful simulation tools will be a key to support research and aircraft HEP design in the coming years. Brazilian research in these challenging areas is in the beginning, and a multidisciplinary collaboration will be critical for success in the next few years.

Road traffic accidents are currently between the seventh and tenth leading cause of death in the world, with approximately 1.35 million people killed per year. Despite extensive efforts by governments, according to the World Health Organization, road accidents still cause far too many deaths, especially among pedestrians, cyclists and two-wheel motor vehicle riders, who together account for almost 50% of road traffic fatalities. In particular, Spain had 410,974 traffic accidents between 2016 and 2019, involving 722,516 vehicles and 61,177 pedestrians with varying degrees of injury. This study uses the Bayesian network method to understand how the pedestrians’ responsibility and actions at the time of the traffic accident affect the injury suffered by said pedestrian, also considering the variables of the road infrastructure and vehicles at the accident site. The results confirm that the variables linked to the unsafe behavior of pedestrians, and their responsibility in traffic accidents, increase the risk of suffering serious or fatal injuries during an accident; for example, if a pedestrian is distracted this increases his/her probability of suffering a severe injury (27.86%) with respect to not being distracted (20.73%). Conditions related to traffic in high-speed areas, areas with no or poor lighting, and areas lacking sidewalks, also record increases in pedestrian injury, as is the case in the age group of pedestrians over 60 years of age.

The article is devoted to main theoretical and practical questions concerning “green” investments in logistics infrastructure objects. This type of investments has certain peculiarities as it deals with the sphere which is related to any kind of business and human’s activity. Logistic infrastructure forms mobility. But no significant change in a separate facility will not give a significant result without a support to the relevant network and the highest intellectual level of its use. Planning of logistic infrastructure should be performed in such way that the positive effect on economic growth was maximal, and the negative impact on the environment is minimal. Thant’s why improving logistics infrastructure facilitates achieving sustainable goals as it works simultaneously for economic, environmental and social development. Thus it is extremely important to implement such tool from “green” economy concept as “green” investments towards logistics infrastructure objects. There were analyzed different theoretical approaches to the definition of “green” investments in the paper. The result of deep research of worlds’ best practical trends for “green” investing in logistics infrastructure objects is provided. There studied separately mentioned tendencies for all subtypes of hard logistics infrastructure: transport (electrification of vehicles, low-carbon transport systems, sustainable fuels), warehouse (automation, distribution centers decentralization, energy-efficient equipment and construction), packaging (suitable for processing packaging materials, moving from plastic to more environmental types of packaging), information infrastructure (energy-efficient servers, cloud computing, reducing the number of toxic materials and water required for the production of electronic devices), customs (The Green Customs Initiative), social (smart containers, automated food waste tracking systems and automated technologies of optical scanning). Also were studied main instruments to attract necessary finance support for “green” investments and analyzed ways how to implement them in Ukrainian market with its peculiarities.
