THE PURPOSE OF THIS STUDY WAS TO DESIGN A SOFTWARE TO OPTIMIZE INVENTORY MANAGEMENT IN THE OFFICE OF INFORMATION TECHNOLOGY AND COMMUNICATIONS (OTIC) OF THE FACULTY OF INDUSTRIAL ENGINEERING AND SYSTEMS OF THE UNIVERSIDAD NACIONAL DEL CALLAO, PERU. THE RESEARCH AROSE DUE TO THE LACK OF AN EFFICIENT SYSTEM THAT MINIMIZES ASSET LOSSES AND REDUCES OPERATIONAL ERRORS IN THE UNIVERSITY CONTEXT, WHERE RESOURCE CONSTRAINTS DEMAND SUSTAINABLE AND ADAPTABLE SOLUTIONS. TO ADDRESS THIS PROBLEM, AN AGILE METHODOLOGICAL APPROACH WAS USED, IMPLEMENTING THE SCRUM METHODOLOGY IN THE SOFTWARE DESIGN, AS WELL AS AN ARCHITECTURE BASED ON MVC (MODEL-VIEW-CONTROLLER) WITH TECHNOLOGIES SUCH AS MYSQL, PHP AND CODEIGNITER. THE EVALUATION OF THE SYSTEM INCLUDED USABILITY SURVEYS TO USERS AND AN EXPERT JUDGMENT, FOCUSED ON THREE DIMENSIONS: RELIABILITY, USABILITY AND DESIGN. THE RESULTS OF THE STUDY SHOWED A HIGH...

Water is an essential element in the life of the human being for which its conservation and good use is necessary, in this work we make a proposal for the development of a low-cost system for water management in order to save on Its consumption, using infrared technology, the results provide a mechanism that can be replicated and at different scales, by the use of commonly used devices.

PARKINSON'S IS A DEGENERATIVE DISEASE THAT IS FUNDAMENTALLY REPRESENTED BY LOSING CONTROL IN THE MOVEMENT OF THE HANDS, IN THE PRESENT WORK, A SYSTEM IS DEVELOPED TO MEASURE THE MOVEMENT OF THE HANDS, CONSIDERING PRONATION IN THE OPENING AND CLOSING ACTIONS OF THE HANDS AND SUPINATION. THE PRESENT DESIGN CONSIDERS THE USE OF INERTIAL SENSORS, RESULTING IN A DEVICE THAT CAN RECORD AND ANALYZE THE SIGNALS OF INVOLUNTARY MOVEMENTS OF PEOPLE WITH PARKINSON'S, THUS BEING ABLE TO ASSESS THE DEGREE OF THIS DISEASE, THE PROPOSED METHODOLOGY CONSIDERS THE POSSIBILITY OF BE ABLE TO BE REPLICATED AND ESCALATED. © 2024, THE AUTHOR(S), UNDER EXCLUSIVE LICENCE TO SPRINGER NATURE SINGAPORE PTE LTD.

Evaluating the costs of electricity generation is important to be able to estimate the variable costs, characterized by the maintenance costs of the generation, transmission and distribution systems. In this work we evaluate the plants that use Camisea natural gas, which is an alternative to the plants that use fossil fuels, not only in terms of costs, but also in terms of the levels of contamination that they cause. The method presented can be taken as a reference for other evaluation mechanisms with similar characteristics.
