Uso de Google meet y gestión escolar en docentes de la Institución Educativa Franz Tamayo Solares, Lima, 2021
El presente trabajo de investigación titulado “Uso de Google meet y Gestión escolar
en docentes de la institución educativa Franz Tamayo Solares, Lima, 2021” tuvo su
origen debido a la pandemia que se está viviendo a causa del Covid – 19, la misma
que afecto a las labores académicas y que obligó a que las clases se realicen de
manera virtual. El estudio se realizó con el objetivo de determinar la relación entre
las variables Uso de Google Meet y Gestión escolar. La metodología que se empleó
es de enfoque cuantitativo, de diseño no experimental de corte transversal y
alcance correlacional. La población de estudio estuvo conformada por 37 docentes
de primaria y secundaria; para la recolección de datos se empleó la técnica de
encuesta a través de cuestionarios. El estudio llegó a la conclusión que no hay una
relación significativa entre el uso de Google Meet y Gestión escolar porque la
correlación de Rho de Spearman evidenció un valor de 0,111 con p-valor = 0,513 >
0,05, indicando que existe suficiente evidencia estadística para no rechazar la
hipótesis nula
Narrando historias personales aprendo a escribir textos narrativos
El proyecto de innovación educativa se denomina: “Narrando historias personales
aprendo a escribir textos narrativos”, surge debido a que en la actualidad los
estudiantes presentan dificultades en la producción de textos. Haciendo un análisis
del PEI de la institución educativa, pude evidenciar que persiste el desinterés por la
lectura, no hay escucha activa, hay escases de producción de textos; al dialogar con
los maestros y maestras manifestaron que aún no logran que sus niños produzcan
textos narrativos con facilidad, estas razones me llevan a concluir que existe un
problema álgido en nuestra escuela; si a esto le sumamos que se encontró que
algunos docentes utilizan estrategias inadecuadas en la producción de textos, es por
ello que tuve la decisión que el objetivo central de este proyecto es lograr que los
docentes empleen estrategias adecuadas en la producción de textos, por tal razón
planteo como proyecto de innovación la aplicación del taller de escritura; que surge
gracias a la magister Sandra Luna Frisancho quien adaptó y desarrollo la propuesta
de Donald Graves y Lucy Clkins denominada taller de escritura que parte de la
narración de una historia personal o algo que le ha pasado al estudiante para
finalmente convertirlo en una hermosa historia. El proyecto se inicia con un análisis
FODA teniendo como base el PEI de la institución educativa así como un diálogo
permanente con los docentes. Seguidamente se construye el árbol de problemas,
árbol de objetivos; asimismo se elabora la matriz de consistencia, señalando el fin
último, el propósito, el objetivo central y los resultados con sus respectivos
indicadores, medios de verificación y supuestos. Finalmente se propone una serie de
actividades, metas, recursos y costos para arribar a los resultados propuestos.Trabajo académic
Regressió del Teulader (Passer domesticus) a l'illa de sa Dragonera
Regression of the House Sparrow (Passer domesticus) at the Dragonera's island. After the six consecutive ringing campaigns durin g the post-nuptial migration to the Dragonera's island (Balearics) it has been observed a progressive reduction of the captures of House Sparrow (Passer domesticus) up to the extinction of its colony in 1992. The causes were analysed and it was proposed to use the presence of the House Sparrow as an indicator of the humanization stage in a natural area
Comparative study of transvaginal ultrasonography and CA 125 in the preoperative evaluation of myometrial invasion in endometrial carcinoma
To compare the ability of transvaginal sonography and serum CA 125
levels to predict myometrial invasion in patients with endometrial carcinoma.
DESIGN AND METHODS: Prospective study in 50 consecutive patients (mean age 60
years, SD 10.5, range 29-77 years) diagnosed as having endometrial cancer and
scheduled for surgical staging. All patients were evaluated by transvaginal
ultrasonography. Endometrial thickness was measured in all cases and myometrial
invasion was estimated as or = 50%. Serum CA 125 level was determined
in each patient. A cut-off level of > or = 35 IU/ml was considered to predict
myometrial invasion of > or = 50%. All patients underwent surgical staging, and
definitive histopathological findings regarding myometrial invasion were used as
the 'gold standard'. Sensitivity, specificity and positive predictive value (PPV)
and negative predictive value (NPV) were calculated for transvaginal
ultrasonography and CA 125 and compared. RESULTS: On histopathological analysis,
myometrial invasion was found to be or = 50% in 15
cases (30%). Mean endometrial thickness in patients with superficial invasion was
significantly lower than in those with deep invasion (13.4 mm (95% CI 11.2-15.7)
vs. 18.7 mm (95% CI 15.0-22.3), respectively; p = 0.014). Median CA 125 was
significantly higher in patients with deep invasion than in those with
superficial invasion (30 IU/ml, interquartile range (IQR) 46.0 vs. 16.9 IU/ml,
IQR 13.9, respectively; p = 0.002). The sensitivity, specificity, PPV and NPV for
transvaginal ultrasonography were 86.7% (95% CI 59.5-98.3), 94.3% (95% CI
80.8-99.3), 86.7% (95% CI 59.5-98.3) and 94.3% (95% CI 80.8-99.3), respectively.
The sensitivity, specificity, PPV and NPV for CA 125 were 40% (95% CI 16.3-67.7),
91.4% (95% CI 76.9-98.2), 66.7% (95% CI 29.9-92.5) and 78% (95% CI 63.4-89.5),
respectively. The sensitivity of transvaginal ultrasonography was significantly
higher than that of CA 125 (p = 0.008). No differences were found in terms of
specificity, PPV or NPV. CONCLUSION: Our results indicate that transvaginal
ultrasonography is more sensitive than CA 125 in predicting myometrial invasion
in endometrial cancer
Caloric restriction, physical exercise, and CB1 receptor blockade as an efficient combined strategy for bodyweight control and cardiometabolic status improvement in male rats
Obesity is critically associated with the development of insulin resistance and related cardiovascular
and kidney diseases. Several strategies for weight loss have been developed but most of them exhibit
a post-intervention rebound effect. Here, we aimed to design combined weight-loss strategies
of caloric restriction, physical exercise, and administration of a CB1 receptor blocker to inhibit
food intake that also accomplish the objectives of lost-weight maintenance and improvement of
cardiovascular and renal function. Diet-induced obesity (DIO) was generated in Sprague Dawley
rats for 12 weeks to test the effects of single or combined strategies (i.e. caloric restriction, mixed
training protocol, and/or administration of appetite suppressant) on caloric intake, body weight,
cardiovascular and renal functionality resulting from a weight-loss intervention period of 3 weeks
followed by 6 weeks of weight maintenance. Consumption of a high-fat diet (HFD) caused a significant
increase in body weight (5th week of the experimental period) and led to the development of insulin
resistance, cardiovascular, and renal alterations. The different interventions tested, resulted in a
significant body weight loss and improved glucose metabolism, aerobic capacity, electrocardiographic
parameters, vascular expression of adhesion molecules and inflammatory mediators, and renal
functionality, reaching values similar to the control normocaloric group or even improving them.
Successful maintenance of lost weight was achieved along a 6-week maintenance period in addition to
adequate health status. In conclusion, the weight-loss and maintenance intervention strategies tested
were efficient at reversing the obesity-related alterations in body weight, glucose metabolism, aerobic
capacity, cardiovascular and renal functionality. The beneficial action was very consistent for caloric
restriction and physical exercise, whereas administration of a CB1 receptor blocker complemented
the effects of the prior interventions in some parameters like body weight or aerobic capacity, and
showed specific actions in renal status, increasing glomerular filtration rate and diuresis. Overall, the
novelty of our study relies on the easy implementation of combined strategies for effective weight
management that resulted in significant health benefits.Spanish Ministry of Science, Innovation and UniversitiesEuropean Commission

Removal of reactive red 120 on Fe-hydrotalcite : isotherms study
HDL-MgFe is a Hydrotalcite that represent a compound lamellar double hydroxide. It was prepared through the continuous co-preparation method. The solid was characterized by surface area measurements, X-ray diffraction and temperature-programmed desorption of CO2. The adsorbent was used for the adsorption of Reactive Red 120 dye, and the factors affecting the adsorption were discussed, including concentration of adsorbent solid and contact time. The adsorption isotherms data were fitted to the Langmuir, Freundlich, Redlich-Peterson, Sips and BET models. The most suitable adsorption conditionswere found at a contact time of 60 min and solidconcentrarion of 2g.L -1 . The results for MgFe hydrotalcite showed a high adsorption with percentage about 90% of dye removal. Langmuir and Redlich-Peterson models were the isotherms that best described the removal process

Alegaciones nutricionales y de salud en productos dirigidos a niños por televisión en España en 2012
OBJECTIVE: To describe the use of nutrition and health claims in products directed at children via television in Spain and to analyse their nutrient profile. METHODS: A cross-sectional study of television food advertisements over 7 days in five Spanish television channels popular among children. The products were classified as core, non-core or miscellaneous, and as either healthy or less healthy, according to the United Kingdom Nutrient Profile Model. We registered all claims contained on the product (packaging and labelling) and its advertisement. We calculated the frequency distributions of health and nutrition claims. RESULTS: During the 420hours of broadcasting, 169 food products were identified, 28.5% in the dairy group and 60.9% in the non-core category. A total of 53.3% of products contained nutrition claims and 26.6% contained health claims; 62.2% of the products with claims were less healthy. Low-fat dairy products were the food category containing the highest percentage of health and nutrition claims. CONCLUSION: Over half of all food products marketed to children via television in Spain made some type of nutrition or health claim. Most of these products were less healthy, which could mislead Spanish consumers.This project has been supported by the Spanish Health Research Fund of the Institute of Health Carlos III (Project ENPY 1015/13) and the Spanish Consumers Organization.S
