    Community-based Rural Tourism (CBRT) has been consolidated as a socially and environmentally responsible alternative in Peru for generating income opportunities for the rural sector. The development of CBRT is still incipient in Peru, and therefore the information generated by public and private institutions is insufficient and in some cases does non-exist. Worldwide, 91% of people use the Internet to find places to visit. However, the use of the Internet brings new challenges for the tourism industry. Different types of consumers, such as Baby Boomers, Generation X and Generation Y, present different challenges. Generation Y is the most active and much more involved in Internet travel planning. With regard to information on ecotourism and / or historic tourism in the Puno region of Peru, there is no information on the web, much less routes according to the needs of tourists. The objective of this work is to develop an Intelligent Digital Platform to apply data science and big data to find smart routes that satisfy tourists' requirements. To obtain the route, a nearest neighbor heuristic was implemented, using 2-opt and the Tabu Search metaheuristic implemented in Python programming language. Computational results demonstrate the efficiency of the Tabu Search algorithm when using data found in the literature and when using real data, guaranteeing the reduction of distances traveled in the shortest time possible, reducing travel costs.

    El ser humano es la razón principal de la existencia de residuos en el mundo. Los residuos sólidos peligrosos son aquellos que por sus características o manejo al que son o van a ser sometidos representan un riesgo significativo para la salud o el ambiente. El incentivo a la colecta selectiva y reciclaje de los residuos utilizados, trae beneficios a la sociedad en la economía de la energía, de los recursos naturales, generación de empleo entre otros. En el sentido de mejorar el aprovechamiento de los recursos naturales, la Logística Inversa proporciona el conocimiento de las formas de reintegración al mercado de los bienes beneficiados por los procesos de producción. Esta trabajo tiene como objetivo principal el de presentar a la Logística Inversa como una alternativa para identificar los principales puntos que caracterizan el impacto ambiental en la cadena productiva de algún producto; además que presentamos un estudio en la cadena productiva de petróleo y subsecuentemente considerar los ciclos productivos posibles de ser implementado por técnicas de Logística Inversa en la industria petrolera, en el producto de aceite lubricante. El estudio de caso se realizó en cuatro ciudades: Lima, Juliaca, Puno y Arequipa, donde se visitó distintas organizaciones, empresas, instituciones, municipalidades, gobierno regional y ministerios que están directamente relacionados con los derivados de petróleo. Se observó que las empresas generadoras de residuos no se responsabilizan por el destino final de los mismos, asimismo el marco legal existente no es conocido e incipiente. El ser humano, debe de entender el propósito de Dios en la creación hasta la actualidad, y mirando el futuro, sin olvidar que es parte de la creación de Dios y que tiene como deber reconciliar al resto de la creación con ÉL.

    Risk can be defined as the relationship between the likelihood of a hazard causing a potential disaster and its consequences. This study aims to assess the likelihood that a new industrial region, located in the state of São Paulo (Brazil), will be flooded, causing the disruption of the mobility system and local economic activities. To fulfill this aim, a new approach is proposed by combining the vector information of the highway network that serves the region with the result of a quasi 2-D raster flood model, generating a set of interpreting rules for classifying the safety of routes. The model called MODCEL is a quasi-2D hydrodynamic model that represents the watershed using compartments called cells, and it was adapted to work using a raster file format in which each pixel is represented as a flow cell connected to its surroundings by the Saint-Venant equations without the inertia terms. Therefore, this study proposes an assessment framework that can be replicated for similar problems of flood risks to mobility. The possible effects of flood events on the accessibility to areas of interest are determined, indicating a possible disruption to economic activities and transportation and allowing for planning alternatives in advance.

    Containers are fundamental elements for the development of international trade; however, it is estimated that there are more than 17 million retired containers stacked in ports around the world. Considering the high costs involved in the process of storing, transporting, or destroying these materials, in addition to their non-degradable nature, it is urgent to develop strategies for the sustainable use of these decommissioned containers. In this context, repurposing these containers into permanent structures is becoming a predominant trend. One solution is converting steel shipping structures into habitable spaces. However, due to the urgency with which Container Houses (CHs) are demanded in case of disasters, they are usually planned to be built as quickly as possible, serving as many people as possible, and do not consider the basic principles of energy efficiency. The performance of the CHs is, then, impaired, including risks of overheating, corrosion, and rust, among others, during service, making them an even more stressful experience for their users who are already in a vulnerable situation. Therefore, the objective of this study is to compare the performance of two thermal insulators applied to a temporary shelter container designed to promptly serve vulnerable populations. The model was developed in Building Information Modeling (BIM) software and simulated in Building Energy Simulation (BES) software, aiming to obtain subsidies for its technical and economic viability analysis. The results indicated that thermal insulators are able to generate significant savings in energy consumption, with mineral wool presenting better long-term performance.

    The growing concern for energy efficiency and the increasing deployment of intermittent renewable energies has led to the development of technologies for capturing, storing, and discharging energy. Supercapacitors can be considered where batteries do not meet the requirements. However, supercapacitors in systems with a slower charge/discharge cycle, such as photovoltaic systems (PVS), present other obstacles that make replacing batteries more challenging. An extensive literature review unveils a knowledge gap regarding a methodological comparison of batteries and supercapacitors. In this study, we address the technological feasibility of intermittent renewable energy generation systems, focusing on storage solutions for PVS energy. We propose a framework according to one of the essential parameters for their application in PVS: Energy Density or Specific Energy (Wh/kg). Through computational modelling, issues related to the intermittency and seasonality of the solar energy source are addressed, evaluating the possible benefits of implementing batteries, supercapacitors, and hybrid solutions in renewable energy generation systems. Also, the characteristics of two hypothetical configurations of photovoltaic systems, off-grid and on-grid, were analysed. This analysis highlights the characteristics of totally isolated systems (e.g., on an island or remote village) and systems connected to the grid (e.g., solar farms), where eliminating the use of batteries can bring significant benefits, in addition to tax incentives, which are decisive in the investment decision-making process. The results clarify the viability of PVS and allow an understanding of parameters that can support the technical decision process between isolated or non-isolated systems, reflecting economic and financial issues.

    El turismo rural comunitario (TRC) es una actividad que contribuye, desde las zonas rurales, al desarrollo económico-social y sostenible de un país. En este trabajo de investigación se tuvo como objetivo desarrollar una Plataforma Inteligente (PI) que satisfaga las necesidades de los distintos actores del TRC. Se presenta la experiencia centrada en Ingeniería de requerimientos, pasando por distintas iteraciones, donde se realizó el análisis FODA, uso de la programación extrema, cumplimiento de la ISO 25010, entre otros. La identificación precisa de los requerimientos fue determinante para que la implementación y usabilidad de la plataforma tenga un impacto social en los actores directos.

    Neste artigo apresentamos heurísticas usando o conceito da meta-heurística Busca Dispersa (BD), desenvolvidas para a solução do Problema de Roteamento de Veículos (PRV) Clássico, detalhando cada uma de suas etapas básicas quando aplicadas ao problema em questão. A Busca Dispersa é um método evolutivo que combina soluções com a finalidade de criar novas soluções de melhor qualidade; ainda que apresente similaridades com os algoritmos genéticos difere dos mesmos em princípios fundamentais. Um aspecto importante da BD é formar soluções com alta qualidade para dirigir a busca a regiões promissoras. Experimentos computacionais foram realizados em quatro conjuntos de dados disponíveis na literatura. Os resultados mostram que a BD é robusta e competitiva em termos de qualidade das soluções obtidas e tempo computacional para o PRV Clássico, para os conjuntos de dados testados.

    The COVID-19 pandemic has driven the rapid evolution and digitization of different tourism sectors through Industry 4.0. However, Community-based Rural Tourism (CRT) has not experienced the same technological advancement. Thus, considering tourism as a powerful socioeconomic driver, this research is based on the relevance of the CRT for the development of rural areas through job creation, preservation of historical-cultural and architectural heritage, and appreciation of the local market. Therefore, the objective of this paper is to present a concept development model of an intelligent digital platform (IDP), where tourism products and services are visualized, articulated, and integrated with the different actors of the CRT, offering a personalized tourist experience. The concept was developed based on Business Process Management and Business Model Canvas (BMC). Thus, through meetings and interviews, it was possible to extract essential information to obtain the necessary know-how for the development of the concept. It was concluded that the COVID-19 pandemic has established a new business scenario, intensifying and accelerating the use of digital tools and ICTs in several sectors, including tourism. However, the use of ICTs in CRT is still incipient. As Peru is a country where rural tourism has a strong tradition, but there are no specific platforms for CRT, which makes the broad dissemination of rural experiences difficult, a BMC template has been developed to integrate the expected objectives, and the application of the proposed framework serves as a guide for other platforms with different niches markets in the tourism sector.
