EFICACIA  DE  LOS    MAPAS CONCEPTUALES COMO RECURSO DIDÁCTICO EN EL APRENDIZAJE DE LAS CIENCIAS SOCIALES EN LA ESCUELA ACADÉMICO PROFESIONAL DE TURISMO, HOTELERÍA Y GASTRONOMÍA DE LA UNIVERSIDAD ALAS PERUANAS EFFECTIVENESS OF MIND MAPS AS TEACHING RESOURCE IN THE LEARNING PROCESS OF SOCIAL SCIENCES IN THE PROFESSIONAL ACADEMIC SCHOOL OF TOURISM, HOSPITALITY AND CUISINE OF PERUVIAN UNIVERSITY ALAS PERUANAS RESUMEN Objetivo. El objetivo de la Investigación fue Determinar que el desconocimiento del manejo de los mapas conceptuales como recurso didáctico influye en el aprendizaje de las Ciencias Sociales en los estudiantes del II ciclo de la Escuela Académico Profesional de Turismo Hotelería y Gastronomía UAP Materiales y Métodos. Para la selección de la muestra se consideró a los estudiantes del II ciclo de la escuela, la técnica de muestreo fue sistemático, se trabajó desarrollando clases haciendo uso de mapas conceptuales en la asignatura de historia de la cultura se aplicó la prueba estadística de hi2 teniendo en cuenta la relación de variables Resultados. Como el valor calculado es mayor al de la tabla (24.894 > 16.919), la hipótesis nula es rechazada, aceptándose la hipótesis alterna H1, con lo cual queda demostrada la hipótesis. Conclusión. El manejo de los mapas conceptuales como recurso didáctico influye significativamente en el aprendizaje de los alumnos, produce un auténtico aprendizaje, porque proporciona conceptos de manera coherente y no arbitraria, “construyendo”, de manera sólida los conceptosABSTRACT Objective. The aim of the research was to determine that the lack of management of mind maps as a teaching resource influences in the learning of Social Sciences students in cycle II of the Professional Academic School of Tourism Hospitality and Gastronomy in Alas Peruanas University.  For the selection of the sample, the students of the second cycle school were considered, the sampling technique was systematic, classes were developed making use of concept maps in the history of culture subject statistic hi2 tests were applied taking in account the variables relation. ResultsAs the calculated value is bigger that the table (24,894> 16,919), the null hypothesis is rejected accepting the alternative hypothesis H1whereupon, the hypothesis ends up being demonstrated. In conclusion. The management of mind maps as a teaching resource influences significantly on the student learning process, It produces an effective learning because it provides concepts in a coherent and not arbitrary way by “building” concepts solidly

Airways oxidative stress, lung function and cognitive impairment in aging.

Abstract BACKGROUND: An altered balance of oxidants/antioxidants is one of the pathological mechanisms of many age-dependent disorders. We aimed to investigate the age-related airways oxidative stress, using non invasive, safe and repeatable techniques; to evaluate the correspondence between systemic and local oxidative stress in healthy subjects of different age ranges; to analyse the correlation between systemic and local oxidative stress with lung function and with cognitive impairment. METHODS: Thirty consecutive healthy high school graduated subjects (8 M, 22 F), divided in three ranges of age ( 60 years) were enrolled. All subjects underwent oxygen free radicals and exhaled nitric oxide measurement (by the diacron reactive oxygen metabolites test and by a rapid-response chemiluminescence nitric oxide analyzer), lung function tests, and cognitive impairment scales (Mini Mental State Examination and Geriatric Depression Scale). RESULTS: A significant increase of oxygen free radicals, exhaled nitric oxide, and Geriatric Depression Scale score and a significant decrease of forced expiratory volume in 1 second and forced expiratory vital capacity from younger to older subjects were identified. Moreover, the significant positive correlation between oxygen free radicals and exhaled nitric oxide, and between oxygen free radicals and exhaled nitric oxide with Geriatric Depression Scale score were found. The significant negative correlation between forced expiratory volume in 1 second and oxygen free radicals or exhaled nitric oxide was also demonstrated. CONCLUSIONS: Our data supports the role of progressive local oxidative stress in damaging the lung function and in inducing depression symptoms

PARP inhibitors affect growth, survival and radiation susceptibility of human alveolar and embryonal rhabdomyosarcoma cell lines

PARP inhibitors (PARPi) are used in a wide range of human solid tumours but a limited evidence is reported in rhabdomyosarcoma (RMS), the most frequent childhood soft-tissue sarcoma. The cellular and molecular effects of Olaparib, a specific PARP1/2 inhibitor, and AZD2461, a newly synthesized PARP1/2/3 inhibitor, were assessed in alveolar and embryonal RMS cells both as single-agent and in combination with ionizing radiation (IR)

High-grade vaginal intraepithelial neoplasia and risk of progression to vaginal cancer. a multicentre study of the Italian Society of Colposcopy and Cervico-Vaginal Pathology (SICPCV)

OBJECTIVE: The aim of this study was to analyse the women with high grade vaginal intraepithelial neoplasia (HG-VaIN), in order to identify a subset of women at higher risk of progression to invasive vaginal cancer. MATERIALS AND METHODS: The medical records of all the women diagnosed with HG-VaIN, and subsequently treated, from January 1995 to December 2013 were analyzed in a multicentre retrospective case series. The rate of progression to invasive vaginal cancer and the potential risk factors were evaluated. RESULTS: 205 women with biopsy diagnosis of HG-VaIN were considered, with a mean follow up of 57 months (range 4-254 months). 12 cases of progression to vaginal squamocellular cancer were observed (5.8%), with a mean time interval from treatment to progression of 54.6 months (range 4-146 months). The rate of progression was significantly higher in women diagnosed with VaIN3 compared with VaIN2 (15.4% vs. 1.4%, p < 0.0001). Women with HG-VaIN and with previous hysterectomy showed a significantly higher rate of progression to invasive vaginal cancer compared to non-hysterectomised women (16.7% vs. 1.4%, p < 0.0001). A higher risk of progression for women with VaIN3 and for women with previous hysterectomy for cervical HPV-related disease was confirmed by multivariable logistic regression analysis. CONCLUSIONS: A higher rate of progression to vaginal cancer was reported in women diagnosed with VaIN3 on biopsy and in women with previous hysterectomy for HPV-related cervical disease. These patients should be considered at higher risk, thus a long lasting and accurate follow up is recommended

Performance comparison of video encoders in light field image compression

Efficient compression plays a significant role in Light Fieldimaging technology because of the huge amount of data neededfor their representation. Video encoders using different strategiesare commonly used for Light Field image compression. In this pa-per, different video encoder implementations including HM, VTM,x265, xvc, VP9, and AV1 are analysed and compared in termsof coding efficiency, and encoder/decoder time-complexity. Lightfield images are compressed as pseudo-videos
