THE EVALUATION OF CHARACTERISTICS AND COMPOSITION OF BEEF CATTLE CARCASS HAS IMPROVED MARKETING. IT REQUIRES TOOLS TO MEASURE IN VIVO, PARAMETERS THAT DEFINE PERFORMANCE AND CARCASS QUALITY IN A FASTER, REPLICABLE AND EFFICIENT METHOD. THE OBJECTIVE OF THIS RESEARCH WAS TO GENERATE MATHEMATICAL MODELS TO ESTIMATE THE AREA OF TOTAL LOIN EYE (AOLT) AND LIVE PERFORMANCE OF SELECTED ANIMALS INTENDED TO PRODUCE PREMIUM MEATS. BASED ON DATA COLLECTED FROM SLAUGHTER PLANTS IN THE BIOBIO REGION (CENTRE SOUTH CHILE), A SIMPLE LINEAR REGRESSION MODEL WAS APPLIED TO ESTIMATE THE AOLT CENTERED ON THE ELLIPSE AREA. THIS WAS USED TO GENERATE MODELS OF MULTIPLE LINEAR REGRESSIONS TO ESTIMATE WEIGHT OF CUTS OF HIGHER COMMERCIAL VALUE UNDER THE STEPWISE PROCEDURE, USING AS SELECTION CRITERIA THE LOWEST VALUE OF THE MEAN SQUARE ERROR (CME). IN CONCLUSION, IT IS POSSIBLE USING THE ELLIPSE AREA TO ESTIMATE IN VIVO THE AOLT AND WEIGHT OF CUTS OF HIGHER COMMERCIAL VALUE IN ANIMALS TO PRODUCE PREMIUM MEATS.

TECHNICAL AND VOCATIONAL EDUCATION PLAYS A KEY ROLE IN DEVELOPMENT, BEING A STRATEGIC AXIS SUPPORTING COMPETITIVENESS AND LABOR INSERTION OF YOUNG PEOPLE. IN CHILE, THE DISCUSSION ON CHALLENGES AND TRANSFORMATIONS IN THE SECONDARY TECHNICAL AND VOCATIONAL EDUCATION SYSTEM (STVE) HAVE BEEN LITTLE VISIBLE DESPITE THE SIGNIFICANT NUMBER OF STUDENTS ENROLLED IN THIS TYPE OF EDUCATION. THIS STUDY EXPLORES STUDENTS AND TEACHER REQUIREMENTS AND LABOR MARKET DEMAND FOR NEW COMPETENCIES GENERATION IN THE PRODUCTIVE SECTOR, SERVICES AND RURAL EXTENSION. USING THE METHODOLOGICAL APPROACH OF PROSPECTIVE, WE IDENTIFY KEY VARIABLES FOR FUTURE TRENDS IN EDUCATIONAL FORMATION. THE MAIN RESULTS SUGGEST A GREATER TRAINING OF STUDENTS IN THE USE OF INFORMATION AND COMMUNICATION TECHNOLOGIES AND STRONGER SOFT SKILL DEVELOPMENT FOR BETTER JOB INSERTION.

LA METODOLOGÍA APRENDIZAJE SERVICIO OFRECE INNUMERABLES OPORTUNIDADES A LA EDUCACIÓN SUPERIOR PARA REFORZAR EL PROCESO ENSEÑANZA APRENDIZAJE MEDIANTE EL VÍNCULO ENTRE EL ESTUDIANTADO Y LA COMUNIDAD. PERMITE AMPLIAR LOS ÁMBITOS DE REFERENCIA DEL TRABAJO DOCENTE, PASANDO DESDE LA SALA DE CLASES HASTA EL TRABAJO EN TERRENO, LO QUE LLEVA A RECONOCER LAS PARTICULARIDADES DEL ENTORNO Y DESCUBRIR LAS NECESIDADES DE LA COMUNIDAD LOCAL. EL PROPÓSITO DE ESTE TRABAJO ES DESCRIBIR LAS ACCIONES DESARROLLADAS POR LA FACULTAD DE CIENCIAS EMPRESARIALES DE LA UNIVERSIDAD DEL BÍO-BÍO DE CHILE PARA LA INCORPORACIÓN E INSTITUCIONALIZACIÓN DE LA METODOLOGÍA APRENDIZAJE SERVICIO COMO PARTE DEL DESARROLLO DE SUS ASIGNATURAS. LOS RESULTADOS INDICAN QUE A LA FECHA HAN PARTICIPADO 901 ESTUDIANTES Y 19 DOCENTES, QUIENES TRABAJAN COLABORATIVAMENTE CON SOCIOS COMUNITARIOS EN JORNADAS DE CAPACITACIÓN Y ASESORÍAS ESPECÍFICAS. A LA FECHA SE HAN ATENDIDO 276 SOCIOS COMUNITARIOS PERTENECIENTES A 20 INSTITUCIONES DE LAS REGIONES DEL BIOBÍO Y DE ÑUBLE, CHILE, QUIENES MAYORITARIAMENTE MUESTRAN ALTO NIVEL DE SATISFACCIÓN CON LAS ACCIONES DESARROLLADAS. ESTA INTERVENCIÓN BRINDA LA OPORTUNIDAD DE AVANZAR EN EL DESARROLLO DE COMPETENCIAS TÉCNICAS, VALORES Y ACTITUDES DEL ESTUDIANTADO Y, JUNTO CON ELLO, LOGRAR UN MAYOR COMPROMISO Y APORTE AL DESARROLLO TERRITORIAL DE LAS REGIONES.

CHILE HAS REDUCED ITS POVERTY LEVELS AT AN INCREASINGLY FAST RATE, ESPECIALLY IN RURAL AREAS, AND THE CHANGES THAT HAVE TAKEN PLACE HAVE GIVEN WAY TO A NEW RURALITY. THIS STUDY ALLOWS US TO QUANTIFY THE IMPORTANCE OF THE STRUCTURAL CHANGES THAT HAVE HAPPENED ON RURAL AND URBAN AREAS DURING THE PERIOD BETWEEN YEARS 2000 AND 2011. THE RESULTS OF THIS RESEARCH SHOW A DEEP CHANGE IN THE INTERACTION OF RURAL HOMES WITH THEIR ENVIRONMENT.
