The aim of this study was to identify and evaluate the incorporation of cushuro cyanobacteria as a food fortifier to improve nutrition in vulnerable populations. A systematic review was conducted following the PRISMA protocol, covering research published between 2010 and 2024, with a total of 23 studies selected. Additionally, an experimental methodology was employed, including infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) to analyze the chemical composition and morphology of Cushuro colonies. The results classified its components into three main groups: hydrocolloids, bioactive molecules, and minerals. In fortified foods, cushuro proved to be versatile and technologically viable, significantly increasing the protein and mineral content in various products without altering organoleptic properties when used at substitution levels between 5% and 10%. Local studies reported moderate sensory acceptability (around 50%), although the intention to recommend was high (over 80%), attributed to its nutritional benefits. The main barriers identified were changes in taste and skepticism about its properties. In conclusion, cushuro emerges as a sustainable and promising resource to address nutritional challenges and promote food security in vulnerable populations.

The main objective of this research was to comparatively evaluate the effect of two types of fermented bioles on the morphological growth characteristics of lettuce (Lactuca sativa) cultivated in pots. The bioles were prepared using different microorganisms for anaerobic fermentation. After a 120-day fermentation period, a 5% foliar fertilizer solution was applied in three treatments: control (T0), LEVA biol (T1), and BACID biol (T2). The distribution followed a completely randomized block design. Plant height, number of leaves, and leaf diameter were evaluated. After 14 days, treatments T1 and T2 showed a 10% and 11% increase in plant height, respectively, compared to T0. On day 21, T2 showed a noticeable increase in the number of leaves. Additionally, on day 14, leaf diameter increased by 5% and 7% in T1 and T2, respectively, compared to T0. These results support the positive effect of bioles on the growth of lettuce in pots. This research contributes to the scientific community by promoting the development of environmentally friendly technologies.

This study focused on improving efficiency at all stages of the construction process, emphasizing the creation of project structures. The Lean Construction philosophy was applied to increase productivity and reduce non-value-adding activities that caused budgetary losses. Tools such as the Last Planner System, five-minute test, Gantt chart, and topographic databases were used to assign tasks and resources (materials, labor, and machinery). Additionally, intermediate planning was implemented to anticipate constraints. The objective was to demonstrate how Lean Construction can reduce non-productive activities and increase efficiency. A quantitative approach was used, with explanatory scope and a non-experimental, cross-sectional design.

This study explores logistics cost optimization in a fishing company in Chimbote, Peru, which faced an 18% rise in distribution expenses. The increase was due to two key issues: suboptimal transport routes and underutilized fleet capacity, with 35% of the fleet remaining idle. To address this, a linear programming optimization model was developed. Its main innovation lies in incorporating industry-specific variables—such as cold chain constraints and product shelf life—into the design of transport routes to distribution centers in Lima, Callao, Piura, Paita, and Chiclayo. After implementation, the model led to a 10–15% reduction in logistics costs and a clear improvement in operational efficiency. A sensitivity analysis confirmed the model’s robustness under scenarios involving fuel price fluctuations, raw material supply variations, and demand spikes. In conclusion, this research not only offered a practical and cost-effective solution for the company studied but also introduced a replicable methodological framework. This framework can be adapted by other perishable food companies in emerging economies to improve logistics performance, ensuring sustainability and competitive advantage. The study highlights the strategic value of integrating advanced optimization tools into supply chain decision-making within the perishables sector

Access to safe drinking water is a fundamental human right, and its guarantee becomes especially critical in marginalized urban contexts. This study evaluated the distribution and microbiological quality of drinking water in 50 samples from different households and the community center of Monte Sinaí, Guayaquil, Ecuador, with the aim of identifying the implications for domestic water management led by women, and the health risks associated with the use of this water. Total coliforms, fecal coliforms, and Escherichia coli, mesophilic aerobic bacteria, Pseudomonas aeruginosa, and Vibrio spp., and coliphages were quantified to determine microbial quality. According to Ecuadorian regulations, 42% of the samples exceeded the permissible limits for fecal coliforms. Additionally, EC, PA, and VI were detected in 50%, 10%, and 24.3% of the samples, respectively. Based on the collected data, 92% of the sampled households are headed by women, who are solely responsible for the collection, storage, and use of water under precarious conditions, often linking it to health issues within their families. The results highlight the need to integrate sanitary engineering with intersectional social approaches in the development of public policies that recognize and address the gender gap, where women bear a significant load in water-related domestic tasks.

The study addresses the application of the 5S methodology to improve inventory management in a company dedicated to the commercialization of mining products. Issues identified included warehouse disorganization, difficulty locating materials, unnecessary overstock, and high operational costs. To tackle these problems, an improvement plan was designed based on the five stages of the 5S methodology: sort, set in order, shine, standardize, and sustain. The actions implemented included the formation of a 5S committee, staff training, labeling of shelves, zoning, cleaning stations, and internal audits. After execution, the company achieved greater organization, reduced search times, improved product visibility, and decreased operational costs. The benefits allowed for a short-term return on investment and created a more efficient work environment. The results validate the effectiveness of 5S as an accessible, practical, and sustainable tool for optimizing logistical processes in small companies within the industrial sector.
