CURRENTLY, THE ISSUE OF SOLID WASTE IS CONSIDERED ONE OF THE BIGGEST PROBLEMS FACING HUMANITY SINCE LACK OF HYGIENE LEADS TO SERIOUS DISEASES THAT CAN LEAD TO DEATH. FOR THIS REASON, THIS PROJECT IS PROPOSED THAT PRIORITIZES PEOPLE'S HEALTH BY NOT GENERATING DIRECT CONTACT WITH THE GARBAGE DUMP AND PREVENTS THE DISPERSION OF GARBAGE WITH A PRESSING SYSTEM THAT, IN ADDITION TO HELPING THE ENVIRONMENT, IMPROVES THE LOGISTICS OF THE UNIVERSITY CITY WHICH IS THE STUDY SITE OF THIS PROJECT. THIS GARBAGE DEVICE THAT PRESSES SOLID WASTE USES A SET OF SENSORS THAT FACILITATE THE CLASSIFICATION OF SOLID WASTE, SUCH AS PLASTICS, CARDBOARD, ALUMINUM CANS, ETC. IN ADDITION, SOLAR PANELS ARE USED SINCE IT IS AN ENVIRONMENTALLY FRIENDLY MEANS AND GENERATES COST SAVINGS IN ELECTRICAL ENERGY CONSUMPTION. © 2024 IEEE.

THE OBJECTIVE OF THIS RESEARCH ARTICLE IS A SIMULATION TO MEASURE THE MAGNITUDE OF ELECTRIC FIELDS, RESISTIVE LOSSES AND THE CORONA EFFECT, THROUGH THE DEVELOPMENT OF A SET OF NUMERICAL FORMULATIONS IN COMSOL AND A MATHEMATICAL MODEL IN MATLAB, GENERATED AROUND A TRANSMISSION LINE 500KV HVDC. TO CARRY OUT THIS SIMULATION, THE COMSOL SOFTWARE WAS FIRST USED JOINTLY, WHICH CONSIDERED THE TYPES OF CONDUCTORS, TENSION LEVEL, SOME BEAM GEOMETRIES AND A 2D MODEL OF THE TOWER AS A TRANSMISSION LINE; AND SECONDLY, THE MATLAB SOFTWARE, WHERE COMMANDS WERE USED THAT ARE ORGANIZED INTO GROUPS OF BOTH INPUT AND OUTPUT CODES ACCOMPANIED BY THE MAIN FACTORS THAT INFLUENCE THE GENERATION OF SAID LOSSES. TO CARRY OUT THIS RESEARCH, ARTICLES FROM THE IEEE, CIGRE, EPRI, AMONG THE MAIN ONES, WERE USED. THEREFORE, THESE SCIENTIFIC CONTRIBUTIONS THAT HELP DEVELOP THE TECHNOLOGICAL SYSTEM OF THE HVDC TRANSMIS...

THE PURPOSE OF THE RESEARCH WAS TO DESIGN A VITAL SIGNS ALERT AND MONITORING SYSTEM WITH VIRTUAL ASSISTANCE THAT IMPROVES CARE FOR OLDER ADULTS WITH VISUAL DISABILITIES. THE METHODOLOGY OF THE STUDY ENCOMPASSED THE APPLIED TYPE OF METHOD WITH AN EXPERIMENTAL RESEARCH DESIGN AND A QUANTITATIVE APPROACH. THE POPULATION STUDIED IS IN THE CONSTITUTIONAL PROVINCE OF CALLAO AND WAS CARRIED OUT ON 10 OLDER ADULTS WITH VISUAL DISABILITIES. THE INFORMATION FROM THE INSTRUMENTS FOR DATA COLLECTION WAS COMPILED, AMONG THE POSITIVE RESULTS OBTAINED WE PRESENT THE RESPONSE OF 10 OLDER ADULTS WITH VISUAL DISABILITIES, WHO VOLUNTARILY PARTICIPATED IN A TEST OF THE USE OF THE PROTOTYPE OF THE VITAL SIGNS MONITORING SYSTEM WITH VIRTUAL ASSISTANCE. THE AVERAGE SCORE OBTAINED IN THIS EVALUATION IS FAVORABLE 4.9, WHICH SHOWS US THAT OUR APPROVAL RATE IS 81.7%. IT IS CONCLUDED THAT THE DESIGN IMPROVES CARE F...

THE OBJECTIVE OF THIS RESEARCH WAS TO DETERMINE THE LEVELS OF STUDENT SATISFACTION IN THE FACULTY OF ECONOMIC SCIENCES DUE TO THE SUDDEN VIRTUALIZATION OF TEACHING IN THE CONTEXT OF THE COVID-19 PANDEMIC. THE TYPE OF RESEARCH WAS BASIC, WITH A DESCRIPTIVE LEVEL - CORRELATIONAL AND CROSS-SECTIONAL. A VIRTUAL QUESTIONNAIRE WAS APPLIED, BASED ON A LIKERT-TYPE SCALE, PREVIOUSLY VALIDATED BY EXPERT JUDGMENT WITH A CRONBACH'S ALPHA RELIABILITY OF 0.862. THE POPULATION CONSISTED OF 1,271 STUDENTS ENROLLED IN THE ACADEMIC SEMESTER 2021-I IN THE FACULTY OF ECONOMIC SCIENCES, THE SAMPLE WAS MADE UP OF 202 STUDENTS AND THE SAMPLING WAS PROBABILISTIC. THE FOLLOWING CONCLUSIONS WERE REACHED: (A) IT WAS IDENTIFIED THAT VIRTUAL EDUCATION AND VIRTUAL LEARNING RESOURCES ARE RELATED TO STUDENT SATISFACTION. (B) STUDENT LEARNING WAS IDENTIFIED AS BEING RELATED TO STUDENT SATISFACTION. (C) IT WAS IDENTIFIED...

THE PURPOSE OF THIS STUDY IS TO MEASURE THE LEVEL OF AIR POLLUTION IN THE DISTRICT OF VENTANILLA AND MI PERU, IN PERU. THE CONCENTRATIONS OF SUSPENDED PARTICLES RANGE FROM 2.5 G TO 10 G, ALSO KNOWN AS PM10, AND THE CONCENTRATIONS OF SUSPENDED PARTICLES LESS THAN 2.5 G, ALSO KNOWN AS PM2.5. THE TASK IS TO MEASURE CO2, PM2.5 AND PM10 POLLUTION TO PROTECT THE HEALTH OF PEOPLE LIVING IN THE REGION UNDER STUDY. A SYSTEM WAS IMPLEMENTED TO MEASURE THE CONCENTRATIONS OF PM10 AND PM2.5 POLLUTANTS IN CO2 POLLUTED AIR. THE MEASUREMENT SYSTEM INCLUDES A DUST AND CO2 SENSOR, AS WELL AS AN AMBIENT TEMPERATURE AND HUMIDITY SENSOR, A DHT11 SENSOR FOR THESE MEASUREMENTS, AND AN ESP8266 MODULE FOR WIRELESS RECORDING AND CLOUD RECORDING. AN ARDUINO UNO R3 AND ESP8266 BOARD USE WIFI TO PROCESS THE SENSOR VALUES. A GOOGLE SHEETS SPREADSHEET AND A PAAS CLOUD COMPUTING SERVICE PROVIDED BY GOOGLE. AN ANN WAS C...

THE OBJECTIVE OF THIS RESEARCH IS TO DEMONSTRATE, THROUGH THE IMPLEMENTATION OF AN OCCUPATIONAL HEALTH AND SAFETY MANAGEMENT SYSTEM BASED ON THE ISO 45001:2018 STANDARD, THE REDUCTION OF OCCUPATIONAL ACCIDENTS IN THE COMPANY PROSEL INGENIERÍA SAC. THIS IS BECAUSE, IN THIS ORGANIZATION, WHICH PROVIDES ELECTRICAL AND CIVIL SERVICES ON BOTH PUBLIC AND PRIVATE ROADS; A HIGH ACCIDENT RATE HAS BEEN EVIDENT DURING THEIR WORK DAYS. THEREFORE, THE APPLIED EXPERIMENTAL METHODOLOGY HAS BEEN USED, THROUGH THE USE OF DESCRIPTIVE AND INFERENTIAL STATISTICS FOR THE INTERPRETATION OF DATA AND VALIDATION OF THE GENERAL AND SPECIFIC HYPOTHESIS. LIKEWISE, AFTER PERFORMING THE SHAPIRO WILK TEST, TO ANALYZE THE DATA OBTAINED FROM THE 16 ACCIDENT RECORDS, WHOSE SIGNIFICANCE VALUE WAS LESS THAN 0.05, THE WILCOXON TEST WAS USED TO DETERMINE THE VALIDITY OF OUR HYPOTHESES, OBTAINING SIGNIFICANCE VALUES. LESS TH...

THE OBJECTIVE OF THIS RESEARCH IS TO DEMONSTRATE, THROUGH THE DESIGN OF A QUALITY MANAGEMENT SYSTEM BASED ON THE ISO 22000:2018 STANDARD, THE INCREASE IN THE PRODUCTIVITY OF THE MOLINERA COMPANY.THIS IS BECAUSE, IN THIS ORGANIZATION, WHOSE FUNCTION IS THE PRODUCTION OF FLOUR, PASTA AND COOKIES DERIVED FROM WHEAT; LOW PRODUCTIVITY HAS BEEN EVIDENT DUE TO THE ABSENCE OF STANDARDIZATION IN ITS PROCESSES AND INSUFFICIENT SYSTEMATIZATION IN FOOD SAFETY MANAGEMENT.THEREFORE, QUANTITATIVE AND NON-EXPERIMENTAL METHODOLOGY HAS BEEN USED, THROUGH THE USE OF DESCRIPTIVE STATISTICS FOR THE INTERPRETATION OF DATA.THIS IS HOW, WHEN CARRYING OUT A BASELINE DIAGNOSIS, WHEN USING THE STATISTICAL SOFTWARE IBM SPSS STATICS, ANALYZING THE INITIAL PRODUCTIVITY AND COMPARING IT WITH THAT OBTAINED AFTER THE PREDICTION OF ESTIMATION VALUES OF THE DESIGN OF THE QUALITY MANAGEMENT SYSTEM FOR THE INTERVAL OF TWELV...

THE CONSTANT CLIMATE CHANGE THAT HAS OCCURRED IN RECENT YEARS AND A CONSIDERABLE POPULATION GROWTH IN PERU IS HAVING A SIGNIFICANT IMPACT ON WATER RESOURCES, WHICH IS WHY IT IS OF INTEREST TO OPTIMIZE WATER RESOURCES, THIS CAN BE ACHIEVED BY IMPLEMENTING A MONITORING SYSTEM FOR WATER RESOURCES, TAKING INTO ACCOUNT THAT IT SEEKS TO BETTER MANAGE THE AVAILABLE WATER RESOURCES. IN THIS SENSE THE IOT TECHNOLOGY, AS A TOOL, CAN PROVIDE US WITH THE ACCESSES TO PERFORM. TAKING INTO ACCOUNT THE USE OF IOT TOOL WE CAN COLLECT IMPORTANT INFORMATION ON WATER RESOURCES, ALL THIS INFORMATION CAN BE VIEWED FROM ANYWHERE IN THE WORLD IN REAL TIME, WITH WHICH WE CAN MANAGE IN AN APPROPRIATE MANNER; WHICH WOULD OPTIMIZE VARIOUS AREAS, MAINLY THAT OF POPULATIONS THAT SCARCE WATER RESOURCES, ALL THIS WITH A SYSTEM THAT INVOLVES PLC THAT MANAGES THE INFORMATION AND ESPECIALLY THAT ALLOWS US TO INTERCONNECT ...
