Influencia del clima organizacional en la satisfacción laboral de los trabajadores de la sede administrativa de la gerencia regional de salud Lambayeque, 2016-2017

El presente trabajo de investigación científica titulado: Influencia del clima organizacional en la satisfacción laboral de los trabajadores de la sede administrativa de la gerencia regional salud Lambayeque, 2016-2017, es de enfoque cuantitativo, explicativo, descriptivo de corte transversal correlacional, no experimental y tuvo como objetivo general determinar la influencia del clima organizacional en la satisfacción laboral de los trabajadores de la sede administrativa de la Gerencia Regional de Salud – Lambayeque. Para la recolección de datos se utilizaron dos instrumentos de medición, que consistieron en dos cuestionarios, uno con 60 preguntas cerradas para medir el clima organizacional y el otro con 35 preguntas cerradas para determinar el nivel de satisfacción laboral, estos permitieron medir cada variable en la escala de Likert. Ambos instrumentos fueron aplicados a 71 trabajadores de la empresa, para la fiabilidad de los instrumentos se utilizó el Alfa de Cronbach, alcanzándose un valor elevado para ambos instrumentos. La información obtenida se procesó a través del programa estadístico SPSS para el análisis descriptivo e inferencial. En relación al clima organizacional se obtuvo que del total de los trabajadores el 84.5% perciben un clima organizacional Indiferente y un 14.5% clima organizacional participativo. En la satisfacción laboral los trabajadores manifiestan tener un nivel de satisfacción medio con un 70.4% y un 28.2% tiene una satisfacción alta. Los resultados evidenciaron que existe una correlación moderada entre el clima organizacional y la satisfacción laboral. Así mismo se evidenció que la variable predictora (clima organizacional) en su conjunto explica su influencia sobre la variable dependiente (satisfacción laboral). Finalmente se analizó esta misma causalidad, pero por dimensiones para conocer cuáles son aquellas dimensiones del clima organizacional que pudieran actuar como predictores de la satisfacción laboral

Semi-vortices and cluster-vorticity: new concepts in the Berezinskii-Kosterlitz-Thouless phase transition

The Berezinskii-Kosterlitz-Thouless (BKT) essential phase transition in the 2d XY model is revisited. Its mechanism is usually described by the (un)binding of vortex--anti-vortex (V--AV) pairs, which does, however, not provide a clear-cut quantitative criterion for criticality. Known sharp criteria are the divergence of the correlation length and a discontinuity of the helicity modulus. Here we propose and probe a new criterion: it is based on the concepts of semi-vortices and cluster vorticity, which are formulated in the framework of the multi-cluster algorithm that we use to simulate the 2d XY model.Comment: 6 pages, LaTex, 7 figures, presented at the "XXXV Reuni\'{o}n Anual de la Divisi\'{o}n de Part\'{i}culas y Campos", of the "Socieded Mexicana de F\'{i}sica", 2 references adde

Application of glass and fan shells to a clay soil to increase its mechanical properties

Improving the mechanical properties of a clayey soil is one of the best options to avoid future structural failures in buildings and is cheaper than replacing all the material. Therefore, this article proposes the use of recycled glass and fan shells as reinforcement materials. This article presents an experimental study to evaluate the mechanical properties of a pure and mixed soil. The clay soil was mixed with 7% of glass (PV) and with 3%, 6%, 10%, 12% and 15% of Fan Shells (PCA) duly crushed and passed through sieve #100. Tests of sieve granulometry, sedimentation granulometry, Atterberg limits, modified proctor and drained consolidated direct cut were performed. This allowed comparing all the data obtained and defining the optimal percentage of the mixture in which the clay improves its mechanical properties. According to the tests carried out, the proportion that has 7% glass and 6% Fan Shells has better results because there is an improvement in its dry density from 1,784 g / cm3 to 1,847 g / cm3, its moisture content increases from 9.4% to 12.1%. In addition, its friction angle improves from 28.9 °to 32 °and cohesion from 0.05 kg / cm2 to 0.1 kg / cm2. These results verify that the properties of the clay soil are improved

Mejoramiento de las propiedades mecánicas de suelos arcillosos empleando valvas de molusco y vidrio en la ciudad de Talara, Piura

Los suelos arcillosos tienen la característica de hincharse cuando son expuestos a la humedad y de contraerse cuando existe sequedad, esto representa un problema especialmente en las cimentaciones que se construyen sobre este tipo de suelo. Por ello, la presente investigación tiene como finalidad evaluar el efecto en las propiedades mecánicas al adicionar vidrio y valvas de molusco triturados a este suelo problemático. La presente tesis tuvo un enfoque cuantitativo, ya que el estudio del suelo arcilloso se realizó mediante la medición de indicadores tales como Corte directo, Proctor Modificado, Límites de Atterberg y Granulometría. Además, el uso del vidrio y valvas de molusco disminuirá los costos de mejoramiento del suelo arcilloso, ya que son materiales que se encuentran por abundancia en la zona de estudio. Y los costos para adquirir estos productos son mínimos. Con esta clase de mejora presentada en la investigación, el suelo arcilloso mejora notablemente, ya que este aumenta su capacidad de soporte. Los resultados muestran que el uso de las valvas de molusco y polvo de vidrio brindan un aumento de la resistencia del suelo arcilloso, además muestra una disminución de las deformaciones transversales que están presentes por la aplicación de cargas sobre el terreno arcilloso. Finalmente, se observó que, al combinar el suelo arcilloso con el polvo de valvas de molusco y polvo de vidrio, esta mezcla disminuye la absorción de agua, convirtiendo de esta manera más estable al terreno arcilloso.Clayey soils have the characteristic of swelling when exposed to moisture and shrinking when there is dryness, this represents a problem especially in foundations that are built on this type of soil. Therefore, the purpose of this research is to evaluate the effect on mechanical properties by adding glass powder and mollusk shell powder to this problem soil. The present thesis had a quantitative focus, since the study of clay soil was carried out by measuring indicators such as Direct Cut, Modified Proctor, Atterberg Limits and Granulometry. In addition, the use of glass powder and mollusk shells will decrease the costs of clay soil improvement, since they are materials found in abundance in the study area. And the costs to purchase these products are minimal. With this kind of improvement presented in research, clayey soil improves markedly as it increases its bearing capacity. The results show that the use of mollusk shells and glass powder provide an increase in the resistance of the clay soil, in addition it shows a decrease in the transverse deformations that are present by the application of loads on the clay soil. Finally, it was observed that, when combining clay soil with shellfish powder and glass powder, this mixture decreases the absorption of water, thus making clay soil more stable.Tesi

The impact of surgical aortic valve replacement on quality of life-a multicenter study:a multicenter study

OBJECTIVES: To explore the effect of surgical aortic valve replacement on quality of life and the variance with age, particularly in patients at risk of deterioration. METHODS: In an observational, multicenter, cohort study of routinely collected health data, patients undergoing and electively operated between January 2011 and January 2015 with pre- and postoperative quality of life data were included. Patients were classified into 3 age groups: 5-point difference as a minimal clinically important difference. Multivariable linear regression analysis, with adjustment for confounders, was used to evaluate the association between age and quality of life. RESULTS: In 899 patients, mean physical health increased from 55 to 66 and mental health from 60 to 66. A minimal clinically important decreased physical health was observed in 12% of patients aged <65 years, 16% of patients aged 65-79 years, and 22% of patients aged ≥80 years (P = .023). A decreased mental health was observed in 15% of patients aged <65 years, 22% of patients aged 65-79 years, and 24% aged ≥80 years (P = .030). Older age and a greater physical and mental score at baseline were associated with a decreased physical and mental quality of life (P < .001). CONCLUSIONS: Patients surviving surgical aortic valve replacement on average improve in physical and mental quality of life; nonetheless, with increasing age patients are at higher risk of experiencing a deterioration

Treatment decision for transcatheter aortic valve implantation: the role of the heart team: Position statement paper of the Dutch Working Group of Transcatheter Heart Interventions

The current paper presents a position statement of the Dutch Working Group of Transcatheter Heart Valve Interventions that describes which patients with aortic stenosis should be considered for transcatheter aortic valve implantation and how this treatment proposal/decision should be made. Given the complexity of the disease and the assessment of its severity, in particular in combination with the continuous emergence of new clinical insights and evidence from physiological and randomised clinical studies plus the introduction of novel innovative treatment modalities, the gatekeeper of the treatment proposal/decision and, thus, of qualification for cost reimbursement is the heart team, which consists of dedicated professionals working in specialised centres

Healthcare-associated prosthetic heart valve, aortic vascular graft, and disseminated Mycobacterium chimaera infections subsequent to open heart surgery

Aims We identified 10 patients with disseminated Mycobacterium chimaera infections subsequent to open-heart surgery at three European Hospitals. Infections originated from the heater-cooler unit of the heart-lung machine. Here we describe clinical aspects and treatment course of this novel clinical entity. Methods and results Interdisciplinary care and follow-up of all patients was documented by the study team. Patients' characteristics, clinical manifestations, microbiological findings, and therapeutic measures including surgical reinterventions were reviewed and treatment outcomes are described. The 10 patients comprise a 1-year-old child and nine adults with a median age of 61 years (range 36-76 years). The median duration from cardiac surgery to diagnosis was 21 (range 5-40) months. All patients had prosthetic material-associated infections with either prosthetic valve endocarditis, aortic graft infection, myocarditis, or infection of the prosthetic material following banding of the pulmonary artery. Extracardiac manifestations preceded cardiovascular disease in some cases. Despite targeted antimicrobial therapy, M. chimaera infection required cardiosurgical reinterventions in eight patients. Six out of 10 patients experienced breakthrough infections, of which four were fatal. Three patients are in a post-treatment monitoring period. Conclusion Healthcare-associated infections due to M. chimaera occurred in patients subsequent to cardiac surgery with extracorporeal circulation and implantation of prosthetic material. Infections became clinically apparent after a time lag of months to years. Mycobacterium chimaera infections are easily missed by routine bacterial diagnostics and outcome is poor despite long-term antimycobacterial therapy, probably because biofilm formation hinders eradication of pathogen

Quality of life after coronary bypass:a multicentre study of routinely collected health data in the Netherlands†

OBJECTIVES: In this study, our aim was to explore how coronary artery bypass grafting affects quality of life, and how this varies with age, particularly with patients at risk of deterioration. METHODS: In a retrospective, multicentre cohort study, patients with isolated coronary artery bypass grafting and electively operated between January 2011 and January 2015 with pre- and postoperative quality-of-life data were included. Patients were classified into 3 age groups: <65, 65-79 and ≥80 years. Quality of life was measured up to 1-year follow-up using the Short Form-12 or the Short Form-36 health survey. A multivariable, linear regression analysis, with an adjustment for confounders, was used to evaluate the association between age and quality of life. RESULTS: A total of 2606 patients were included in this study. Upon one-year of follow-up, the mean physical health of patients increased from 54 at baseline to 68, and mental health increased from 60 to 67. We observed decreased mental health in 20% of patients aged <65 years, 20% of patients aged 65-79 years and 29% of patients aged ≥80 years (P = 0.039). In this study, age was not associated with a lower physical or mental component score (P = 0.054 and P = 0.13, respectively). Independent risk factors for a decrease in quality of life consist of a better physical and mental score at baseline (P < 0.001) and a reduced left ventricular function (P < 0.001). CONCLUSIONS: Most patients experience a relevant increase in physical and mental quality of life, but a proportion of patients aged ≥80 years undergo significant deterioration in mental health
