Propuesta de una metodología para la gestión económica de la obra en marcha. Aplicación práctica al proyecto de una infraestructura civil

[EN] Civil Engineers possess sufficient technical information related to construction and engineering, despite this, they do not have enough information or preparation to understand the economic performance of a work. This is because construction projects do not have standardized methods or procedures and each work that is executed is different. This proposal deals with the economic management of works, work will be done by simulating the execution of a work site in Pedralabes, Valencia; In this simulation, two scenarios of economic management are presented, depending on the low offered by the contractor. The purpose of this work is to start theoretically in the concepts used to manage a work and start in the practical to develop the ability to analyze the moment in which a work is managed. We tried to make the simulation as real as possible in order to cover a greater number of variables and uncertainty, we can see that the proposed method is not only limited to the economic management of the items, but can also be used for personnel control , machinery and tools if desired. The economic management of a work is one of the most important aspects of the construction sector after all a project is managed by a company whose purpose is to generate income to make a profit.[CA] Els enginyers civils posseeixen suficient informació tècnica relacionada amb la construcció però a enginyeria, malgrat tot, no compten amb la suficient informació o preparació per entendre el funcionament econòmic d'una obra. Això és degut a que els projectes de construcció no tenen mètodes ni procediments estandarditzats i cada obra que es du a terme és diferent. En aquesta proposta es tracta la gestió econòmica d'obres i es treballarà fent una simulació de l'execució d'una obra vial a Pedralba, València; en aquesta simulació es presenten dos escenaris de gestió econòmica depenent de la baixa ofertada pel contractista. La finalitat d' aquest treball és la iniciació de manera teòrica als conceptes utilitzats per la gestió d'una obra i la iniciació en lo pràctica per desenvolupar la capacitat d'anàlisi en el moment en el que es gestiona una obra. S'ha intentat fer la simulació de la manera més real possible per a així poder incloure un major número de variables i d'incertesa. Es podrà veure que el mètode proposat no només es limita a la gestió econòmica de les partides, ja que pot utilitzar-se també per el control de personal, maquinària y eines si així es desitja. La gestió econòmica d'una obra es un dels aspectes més importants del sector de la construcció, perquè al cap i a la fi, un projecte és gestionat per una empresa que té com objectiu generar ingressos per poder obtenir beneficis.[ES] Los Ingenieros Civiles poseen suficiente información técnica relacionada con construcción y a ingeniería, a pesar de esto, no cuentan con la suficiente información o preparación para entender el funcionamiento económico de una obra.

La gestión económica de una obra es uno de los aspectos más importante del sector construcción al fin y al cabo un proyecto es gestionado por una empresa que tiene como fin generar ingresos para obtener ganancias.Cruz Reyes, MFDL.

Aplicación, cenizas de conchas de abanico para estabilización nivel sub subrasante en el camino vecinal Nuevo Tambo Real Chimbote – 2022

El trabajo de investigación titula “Aplicación, cenizas de conchas de abanico para estabilización nivel sub subrasante en el camino vecinal Nuevo Tambo Real Chimbote – 2022”, de acuerdo a lo planteado nace la pregunta ¿De qué manera la aplicación de cenizas de conchas de abanico mejorara la estabilización del suelo a nivel de subrasante en el camino vecinal Nuevo Tambo Real, Chimbote – 2022? La metodología empleada fue experimental, porque no se manipularon las variables, siendo del tipo aplicado, donde se concluyó que para las propiedades físicas del material se determinó una clasificación del tipo SP-SM, SP-SM, SP,SP, mientras para las propiedades del material se determinó una capacidad portante del suelo se determinó para C1= 16.2%, C2=15.0%, C3=17.2% y para C4=16.3%, así mismo respecto a las propiedades mecánicas del suelo al añadir la adición del 5 % de cenizas de conchas de abanicos se obtuvo una densidad máxima seca de 2.166 gr/cm3 y un OCH de 6.09 % y un CBR del 17.2 %, para la propuesta de diseño del paquete estructural fue 15 cm para la Subbase , por ultimo para la prueba de hipótesis se determinó que demuestra que en resumen se rechaza la hipótesis nula debido que el grado de significancia fue menor a 0.05, demostrando que las cenizas de conchas de abanico mejora las propiedades mecánicas del suelo, para estabilización de la Subrasante

Effects of Pilates training on sleep quality, anxiety, depression and fatigue in postmenopausal women: A randomized controlled trial.

Objectives: To analyze the effects that a Pilates-based exercise program has on sleep quality, anxiety, depression and fatigue in community-dwelling Spanish postmenopausal women aged 60 and over. Study design: A total of 110 women (69.15 ± 8.94 years) participated in this randomized controlled trial. They were randomly allocated to either a control (n = 55) or a Pilates (n = 55) group. Main outcome measures: Sleep quality and self-perceived fatigue were assessed by the Pittsburgh Sleep Quality Index (PSQI) and the Fatigue Severity Scale, respectively. Anxiety and depression were evaluated using the Hospital Anxiety and Depression Scale (HADS). Results: Significant improvements were observed after Pilates training in all PSQI domains as well as in the PSQI total score, with small to medium-size effects, while significant between-group differences in post-intervention measures were observed only for sleep duration (d = 0.69) and sleep disturbances (d = 0.78). Moreover, intraand inter-group statistical differences were observed for depression (d = 0.39 and d = 0.86, respectively) and for anxiety (d = 0.43 and d = 1.27 respectively). Finally, participants in the Pilates group experienced a decrease in self-perceived fatigue after the intervention period (d = 0.32). Conclusions: For community-dwelling Spanish postmenopausal women aged 60 years and over, a twelve-week Pilates exercise intervention has beneficial effects on sleep quality, anxiety, depression and fatigue.This work was supported by the project UJA2016/08/08, University of Jaén

Sarcopenia and sarcopenic obesity in Spanish community-dwelling middleaged and older women: Association with balance confidence, fear of falling and fall risk

Objectives: To analyze the association of sarcopenia, obesity, and sarcopenic obesity (SO) with fear of falling (FoF) and balance confidence in a Spanish sample of middle-aged and older community-dwelling women. Study design and outcome measures: A total of 235 women (69.21 ± 7.56 years) participated in this study. Body composition (bioelectrical impedance analysis), hand-grip strength, and physical performance (gait speed) were evaluated for the diagnosis of sarcopenia, obesity, and SO. Anxiety and depression were measured using the Hospital Anxiety and Depression Scale. The Activities-Specific Balance Confidence Scale (ABC) and the Falls Efficacy Scale-International (FES-I) were employed to assess FoF and balance confidence, respectively. Scores of > 26 on the FES-I and < 67% on the ABC were used to identify women at risk of falling. The independent associations of sarcopenia, obesity and SO with FoF, balance confidence, and fall risk were evaluated by multivariate linear and logistic regressions, adjusting for potential confounding variables. Results: 27.23% and 18.72% of women presented with sarcopenia and SO, respectively. Gait speed, body mass index (BMI), and fall history were independently associated with ABC score (adjusted-R2 = 0.152) and fall risk (ABC) (adjusted-R2 = 0.115). FES-I score was independently associated (adjusted-R2 = 0.193) with fall history, gait speed, BMI, and depression, which, together with obesity (BMI) and SO, remained independent factors for fall risk measured as FES-I score (adjusted-R2 = 0.243). Conclusion: In community-dwelling middle-aged and older Spanish women, BMI, gait speed, and fall history were independently associated with FoF, balance confidence, and fall risk. Depression was related only to FoF, and, together with obesity (BMI) and SO, was an independent predictor of fall risk as assessed by the FES-I

MEDICINA DE ESTILO DE VIDA Y RIESGO DE DESARROLLAR DIABETES MELLITUS EN PERSONAL DE LA CLÍNICA GOOD HOPE, LIMA – PERÚ, 2017.: LIFESTYLE MEDICINE AND DIABETES RISK IN STAFF OF GOOD HOPE CLINIC, LIMA-PERU 2017

Abstract &nbsp; Diabetes is a chronic disease that occurs when the pancreas does not produce enough insulin or when the body does not use efficiently the insulin it produces. According to the ENDES 2013, it has found a prevalence of overweight of 33.8% and obesity of 18.3%. Objective: Determine the results of the risk test for diabetes mellitus type 2 of the American Diabetes Society in the care and administrative personnel of a particular clinic. Methods: Observational, cross-sectional, analytical study that evaluates the probability of workers suffering from diabetes mellitus. The population of the study will be made up of workers, both clinical and administrative staff of the institution. Results: 34% of the population had normal BMI, 49% were overweight and 18.3% were obese. 15% of the studied population is at risk of developing diabetes mellitus type 2 according to the risk test for diabetes mellitus type 2 of the American Diabetes Society. The factors significantly associated with the risk of developing diabetes were older than 40 years OR: 10,14 IC95% 4,29, 23,98, p: 0.000; male sex OR: 2,35 % 1,06-5,21, p: 0.03; family history of diabetes OR: 6,330 IC95% 2,76-14,51, p: 0.000; BMI greater than 25 OR: 19,706 IC95% 2,62-147,96, p: 0.000 and physical activity OR: 28,95 IC95% 3,86-217,18; as well as the diagnosis of arterial hypertension OR: 13.500 IC95% 4.87-37.38. Conclusion: The risk found to develop diabetes was 15%, being higher in the administrative group than in the healthcare group. The factors associated with the risk of developing diabetes are directly linked to lifestyle medicine. Key words: Diabetes Mellitus; Risk Factors; Massive Screening.
