This study performs a systematic review of the literature on oxygen enrichment, oxygen lances and oxy-fuel technologies based on the use of pure oxygen in the combustion process in reheating furnaces for hot rolling mills, focusing on the improvement of combustion efficiency and productivity. The information search was carried out in the Scopus database, where 18 articles were identified and selected using the PRISMA and PICO methods. Subsequently, a bibliometric analysis was performed to obtain a deeper insight into the research conducted on oxygen enrichment and oxy-combustion as technologies in heating processes. Tools such as VOSviewer to visualize the cooperation between researchers from different countries in related scientific production and Bibliometrix to graphically represent the countries with the highest scientific production were used.

The objective of this research is to reduce the distances and transportation times of the production process of desk calendars in a printing plant, using the Systematic Layout Planning (SLP) methodology. This methodology analyzes the transportation routes in a process, and by assessing the intensity of the relationships between workstations, a sketch is developed that allows the reorganization of the distribution of the work area, allowing the correction of chaotic routes (spaghetti phenomenon), which hide unnecessary transport that does not add value. In the study it was possible to go from a chaotic route that the operators made between work stations, to a more organized one that could be visualized through the route diagram, likewise through the process flow diagram (PFD) there was a decrease in the distance from 92.7 meters to 35.5 meters, 38% improvement over the initial situation, and a decrease in the time of completion of each calendar of 157 seconds, which allowed to increase production by 4.7 calendars per batch

The objective of the study was to establish to what extent the Markovian prospective analysis on Financial Health is influenced by Human Resources and Production-Operation in Commerce MSMEs in Huacho, Peru. The study is non-experimental and prospective, using software such as POM QM and Crystall Ball. The sample was 399 commercial MSMEs, extracted from RELAYN, covering 15 items. The results showed that the instrument was highly reliable Cronbach's α = 0.962, McDonald's Ω = 0.962. The normality test indicated a non-normal distribution p-value = 0.010 justifying the use of non-parametric tests. The Friedman test confirmed significant differences between the dimensions p-value = 0.000 in the Multiple Regression, the equation obtained was: Finance = 5.627 + 1.343 (LoyalTeam) − 0.193 (CapableTeam) + 0.017 (GoodTreatment) − 0.296 (Productivity) + 0.833 (Well-being) + 0.969 (Quality) − 0.228 (Just in Time) + 0.089 (Delivery) + 0.225 (Inventories) + 0.979 (Costs). The Spearman Correlation highlighted that Delivery Time (r = 0.481), Product Quality (r = 0.499) and Interpersonal Relationship (r = 0.467) significantly impact Financial Health. Markov analysis showed that although financial stability improved from 13.03% to 31%, it remains at risk of deterioration, as the probability of falling into critical economics increases. Monte Carlo simulation confirmed that March 2025 is the critical point with 77.8% impact. In conclusion, the general hypothesis is validated, the prospective Markovian analysis on the Financial Health of SMEs in Huacho, Peru, is significantly influenced by Human Resources and Production-Operation, highlighting the need for early strategies to stabilize the economy of SMEs.

Efficient medical information management is crucial for optimizing resources in public entities. However, the lack of an organized system has led to high operational costs and decreased efficiency in Occupational Health and Safety services. To address this issue, this study evaluated the impact of digitalization through the implementation of an Electronic Record System. A pre-experimental design was employed with a population of 1,800 public servants, comparing digitalization with the standardization of document management processes. The analysis determined that the former was the most effective option, enhancing information accessibility, usability, and sustainability. Results showed a 67% improvement in operational efficiency and an annual cost reduction of $6,965.76. Furthermore, financial indicators confirmed the project's feasibility, with a Net Present Value (NPV) of $580.48, an Internal Rate of Return (IRR) of 22%, and a Benefit-Cost (B/C) ratio of 1.72. These findings highlight the positive impact of digitalization in public administration, optimizing medical information management and promoting more efficient resource utilization. Strengthening technological infrastructure and training personnel is recommended to ensure the system's sustainability, fostering more effective and transparent management.

This work presents a quaternion-based methodology for trajectory control of a 5-degree-of-freedom (DOF) collaborative robot. The mathematical representation of quaternions and their application in trajectory interpolation are addressed, avoiding issues such as singularities and discontinuities found in other representations like Euler angles and rotation matrices. The interpolation method with a 4-1-4 parabolic blend is implemented, prioritizing position and velocity continuity while maintaining minimal acceleration variation. The method is validated through simulations in MATLAB/Simulink, comparing the results obtained using homogeneous transformation matrices and quaternions. The results show that using quaternions reduces trajectory tracking errors and optimizes the system's computational performance. Finally, the numerical computation results of both methods are discussed.

Urban and infrastructure development implies an increased demand for ready-mix concrete. Small companies producing ready-mix concrete must optimize their operations to improve productivity and meet demand. In this sense, our research applies the principles of Industry 4.0 to process monitoring, automation, and technical assistance to improve the productive efficiency of the material loading process in a ready-mix concrete plant. The methodology includes a literature review, field observation, and interviews with operating personnel. This information allowed the researcher to redesign the materials loading process, integrating monitoring technologies, such as the GPS Logger, to record operating times. In addition, a metal hopper was implemented to automate and facilitate the mixing of materials, and subsequently, employees were trained in the redesigned process using Industry 4.0 technologies. We validated the solution through a 15-day pilot test, which showed a reduction in cement loading time from 9 minutes and 59 seconds to 3 minutes and 33 seconds, reducing material waste by 3.5%. Reduced the total material loading time from 42 minutes to 36 minutes per mixer, increasing daily production by 22% and improving operating efficiency by 42.6%. The economic evaluation confirmed the project's feasibility, with an NPV of S/. 23,020.73, a C/B ratio of 1.79 and an IRR of 22.22%, recovering the investment in only five months. These results demonstrate that the proposal optimizes processes and increases the company's competitiveness, paving the way for significant growth in daily production.
