Traceability and monitoring of industrial processes are becoming more important to assure the value of final products. Blockchain technology emerged as part of a movement linked to criptocurrencies and the Internet of Things, providing nice-to-have features such as traceability, authenticity and security to sectors willing to use this technology. In the retail industry, blockchain offers users the possibility to monitor details about time and place of elaboration, the origin of raw materials, the quality of materials involved in the manufacturing processes, information on the people or companies that work on it, etc. It allows to control and monitor textile articles, from their production or importing initial steps, up to their acquisition by the end consumer, using the blockchain as a means of tracking and identification during the whole process. This technology can also be used by the apparel industry in general and, more specifically, for ready-to-wear clothing, for tracing suppliers and customers along the entire logistics chain. The goal of this paper is to introduce the more recent traceability schemes for the apparel industry together with the proposal of a framework for ready-to-wear clothing which allows to ensure the transparency in the supply chain, clothing authenticity, reliability and integrity, and validity of the retail final products, and of the elements that compose the whole supply chain. In order to illustrate the proposal, a case study on a women’s shirt from an apparel and fashion company, where a private and open blockchain is used for tracing the product, is included. Blockchain actors are proposed for each product stage.

Environmental education (EE) has become the only tool for environmental sustainability in training processes in Colombia, for basic cycles in primary and secondary, as well as university education. EE tends to transform human actions in nature, based on multidisciplinary knowledge that supports decision-making. Its goal is to generate a change in social behavior in order to achieve the recovery, conservation, and preservation of the environment. In Colombia, education for sustainable development (ESD) is embedded in EE. These educational models (EE and ESD) seek to achieve sustainable development goals (SDGs), which generally seek the economic and social well-being of nations, both for current and future generations. Environmental engineering is a relatively new degree course in Colombia and Latin America since it appeared in the mid-nineties, and it must involve EE within its curriculum. Students are trained in this trend. This research intends to demonstrate, through a curricular review of the environmental engineering curricula and also surveying students from this degree, the level of inclusion of EE in Latin America. Strengths are identified in the curricula, such as the strong presence of EE in disciplinary subjects and opportunities for improvement based on the needs of the students. The situation in South America is also included in this study.

One of the diseases that could affect diabetic patients is the diabetic foot problem. Unnoticed minor injuries and subsequent infection can lead to ischemic ulceration, and may end in a foot amputation. Preliminary studies have shown that there is a positive relationship between increased skin temperature and the pre–ulceration phase. Hence, we have carried out a review on wearables, medical devices, and sensors used specifically for collecting vital data. In particular, we are interested in the measure of the foot–temperature. Since there is a large amount of this type of medical wearables, we will focus on those used to measure temperature and developed in Spain.

The most popular encryption scheme based on elliptic curves is the Elliptic Curve Integrated Encryption Scheme (ECIES), which is included in ANSI X9.63, IEEE 1363a, ISO/IEC 18033-2, and SECG SEC 1. These standards offer many ECIES options, not always compatible, making it difficult to decide what parameters and cryptographic elements to use in a specific deployment scenario. In this work, the authors show that a secure and practical implementation of ECIES can only be compatible with two of the four previously mentioned standards. They also provide the list of functions and options that must be used in such an implementation. Finally, they present the results obtained when testing this ECIES version implemented as a Java application, which allows them to offer some comments about the performance and feasibility of their proposed solution.

Wireless Sensor Networks (WSNs) are a set of sensor devices deployed in a given area that form a network without a pre-established architecture. Recently, malware has increased as a potential vulnerability for the Internet of Things, and consequently for these networks. The spread of malware on wireless sensor networks has been studied from different perspectives, excluding individual characteristics in most of the models proposed. The primary goal of this work is to introduce an Agent-Based Model for analysing malware propagation on these networks, and its agents, coefficients and transition rules are detailed. Finally, some simulations of the proposed model are included.
