Laboratorio de Referencia Regional de Salud Pública de San Martín

Un Laboratorio de Referencia Regional de Salud Pública es el responsable de realizar acciones de diagnóstico, control de calidad, investigaciones y vigilancia epidemiológica dentro de la región San Martín a fin de contribuir con el control y vigilancia de la salud pública en la región. Su infraestructura debe considerar requerimientos de alta calidad, siguiendo los criterios establecidos por las normativas nacionales e internacionales vinculadas a la calidad de laboratorios, y considerando el equipamiento y las condiciones ambientales óptimas para el desarrollo de sus acciones dentro de cada uno de los ambientes de laboratorio, garantizando la calidad de sus procedimientos y el control biológico. En la actualidad, en el Perú, gran parte de los laboratorios que desempeñan funciones de vigilancia en el sector público no se encuentran en correctas condiciones para realizar las funciones que les corresponden ya que no cuentan con la infraestructura apropiada, lo cual pone en riesgo la eficacia de sus procedimientos de diagnóstico, control de calidad, investigaciones y vigilancia epidemiológica. Si bien existen laboratorios con óptimas condiciones de infraestructura y equipamiento adecuado, éstos se encuentran en el sector privado, lo cual genera que la población demandante tenga que pagar altos costos para obtener los servicios de diagnóstico, control de calidad y otros. El planteamiento arquitectónico permite el correcto desarrollo de las funciones de diagnóstico, control de calidad, investigaciones y vigilancia epidemiológica, en favor de la salud pública, a través de zonas de laboratorios óptimamente diseñados mediante una organización unidireccional, en donde todos los procedimientos se podrán realizar de manera eficaz y cumpliendo con los requerimientos establecidos en las normativas nacionales e internacionales. El proyecto desarrolla el diseño arquitectónico y las especialidades de ingeniería de la solución técnica del Laboratorio de Referencia Regional de Salud Pública de San Martín, haciendo énfasis en el desarrollo a detalle de las infraestructuras de los bloques del Laboratorio de Enfermedades Infecciosas y Laboratorio de Control de Calidad de Alimentos y Aguas.A Regional Public Health Reference Laboratory is in charge of carrying out diagnostic actions, quality control, investigations, and epidemiological surveillance within the San Martín region in order to contribute to the control and surveillance of public health in the region. Its infrastructure must consider high quality requirements, following the criteria established by national and international regulations related to the quality of laboratories, and considering the equipment and appropriate environmental conditions for the development of its activities within each of the laboratory environments, guaranteeing the quality of its procedures and biological control. At present, in Peru, a large part of the laboratories that carry out surveillance functions in the public sector are not in good conditions to carry out the functions that correspond to them since they do not have the appropriate infrastructure, which puts the quality of its diagnostic procedures, quality control, investigations and epidemiological surveillance at risk. Although there are laboratories with optimal infrastructure conditions and adequate equipment, they are in the private sector, which means that the demanding population has to pay high costs to obtain diagnostic, quality control and other services. The architectural plan allows the correct development of the functions of diagnosis, quality control, investigations and epidemiological surveillance, for the benefit of the public health of the population, through blocks of laboratories correctly designed through a unidirectional organization, where all the procedures can be carried out efficiently and complying with the quality requirements of national and international regulations. The project develops the design of the architecture and specialties of the general plan of the San Martín Regional Public Health Reference Laboratory, emphasizing the detailed development of the infrastructures of the blocks of the Infectious Diseases Laboratory and Quality Control Laboratory of Food and Water.Tesi

Propuesta de un plan estratégico incluyendo gestión de calidad para productores de maíz morado del Valle de Condebamba con miras a crear oferta exportable

RESUMEN Desde la repartición de tierras propuesta por un sistema gubernamental ineficiente, el sector agrícola y el trabajo mismo de los agricultores ha sido infravalorado y catalogado como una actividad muy básica, la cual no necesita mejora y/o evolución. En tiempos actuales, donde el consumismo se ha intensificado en todo el mundo, y además es requerida la calidad de los productos cultivados, las zonas productoras de nuestro país, y particularmente de Cajamarca, van quedando rezagadas por su falta de competitividad ante otras zonas de producción, logrando menores rangos de beneficios y estancando su bienestar social. Sumado a ello, el desinterés y desconfianza que han creado programas inconclusos de capacitación y mejora de procesos en el sector, ha hecho que los agricultores se cierren a la búsqueda mejoras en el desarrollo de sus cultivos, manteniendo prácticas muy antiguas, donde el resultado es un producto de regular o baja calidad, y aprovechamiento de parte de los compradores o acopiadores al no pagar un justo precio por dichos cultivos. Esta investigación propone la creación de un Plan Estratégico el cual incluya sistemas de Gestión de Calidad, donde se oriente a los productores de maíz morado del Valle de Condebamba, para crear un producto que sea considerado como oferta exportable, al cumplir con los requerimientos necesarios para la entrada hacia mercados extranjeros, dando como resultado una sustancial mejora en la calidad de vida de los pobladores de la zona.ABSTRACT Since the allocation of land proposed by an inefficient government system, the agricultural sector and the work of farmers have been undervalued and catalogued as a very basic activity, which does not need improvement and / or evolution. In current times, where consumerism has intensified throughout the world, and the quality of cultivated products is also required, the producing areas of our country, and particularly of Cajamarca, are shelved because of their lack of competitiveness in comparative with other areas of Production, their achieving lower profit ranges and stagnating social welfare. Also, the lack of interest and mistrust that have created unfinished programs of training and improvement of processes in the sector, has caused farmers to close the search for improvements in the development of their crops, maintaining very old techniques, where the result is a product of regular or low quality, and use of part of buyers or intermediaries not paying a fair price for such crops. This research proposes the creation of a Strategic Plan which includes Quality Management systems, which will guide the producers of purple corn in the Condebamba Valley, to create a product that is considered as an exportable offer, by complying with the necessary requirements for The entrance to foreign markets, resulting in a substantial improvement in the quality of life of the residents of the area

Decision Support Systems for the Efficiency Social Networks of Small and Medium Enterprises

The objective of this literature review article was to develop a framework of reference for the use of social networks as a decision support systems tool for the efficiency of small and medium enterprises. Twenty (20) research articles were reviewed from 2011 to 2017 that were associated with the topics of decision support systems, strategic decisions, and social networks. The research findings suggest that the use of decision support systems help the organization gain a competitive advantage, improve performance by analyzing the data obtained, and the data extracted from social networks add value to the company with low investment. Social networks have transformed the availability of information for their customers, making available a set of tools for searching, debugging, and validating data from both: individuals and organizations [19]. The use of social media is an effective modality for the development of relationships with clients and employees [10]

Rendering Bio-inert Low-Density Polyethylene Amenable for Biodegradation via Fast High Throughput Reactive Extrusion Assisted Oxidation

An energy-efficient high throughput pre-treatment of low-density polyethylene (LDPE) using a fast, reactive extrusion (REX) assisted oxidation technique followed by bacterial attachment as an indicator for bio-amenability was studied. Silicon dioxide (SiO2) was selected as a model oxidizing and catalytic reagent with the REX process demonstrated to be effective both in the presence and absence of the catalyst. Optimized 5-min duration pre-treatment conditions were determined using Box-Behnken design (BBD) with respect to screws speed, operating temperature, and concentration of SiO2. The crystallinity index, carbonyl index and weight loss (%) of LDPE were used as the studied responses for BDD. FTIR and DSC spectra of the residual LDPE obtained after pre-treatment with the REX assisted oxidation technique showed a significant increase in residual LDPE carbonyl index from 0 to 1.04 and a decrease of LDPE crystallinity index from 29 to 18%. Up to fivefold molecular weight reductions were also demonstrated using gel permeation chromatography. Optimum LDPE pre-treatment with a duration of 5 min was obtained at low screw speed (50 rpm), operating temperature of 380-390 degrees C and variable concentration of SiO2 (0 and 2% (w/w)) indicating that effective pre-treatment can occur under noncatalytic and catalysed conditions. Biofilms were successfully formed on pre-treated LDPE samples after 14 days of incubation. Furthermore, the technique proposed in this study is expected to provide a high throughput approach for pre-treatment of pervasive recalcitrant PE-based plastics to reduce their bio inertness.Related to published version:[https://imagine.imgge.bg.ac.rs/handle/123456789/1575]Peer-reviewed manuscript: Ferrero, P., Attallah, O.

Evaluation of the potential use of biosolids in corn crop in the municipality of Puebla, Mexico

Purpose Due to the urgent need for sustainable agro-industrial waste management, a field experiment was conducted to evaluate the application of biosolids as organic fertilizer in a corn cultivation crop. In addition, to achieve food security, the study aimed to assess metals concentrations in soil and maize plants and enrichment factors (EF) for soils and plants.Method Four sites with a biosolids application were studied and  compared against a control. Physicochemical properties of soils and heavy metal contents were evaluated after one year of application of biosolids. Metal concentrations, average kernel yield and biomass were measured in corn plants.Results The results demonstrated that the biosolids increased the content of organic matter, nitrogen, phosphorus, and exchangeable bases in the soil. In addition, the concentration of heavy metals in soils with biosolids was higher than in soils without treatment, and the concentration of heavy metals in the corn kernels did not exceed the maximum recommended limits. However, EF values showed a considerable contamination grade due to the accumulation of metals.Conclusion Some of the physical and chemical characteristics of soil were improved by incorporating biosolids, but the metal content in the soil increased. Also, the application of biosolids increased the plant height  and corn yield. Therefore, biosolids can be used as organic fertilizer sources; however, it is necessary to carry out periodic evaluations to ensure low levels of enrichment in crops and soil, thus guaranteeing the safety of biosolids as soil fertilizers

Calibration of a trinocular system formed with wide angle lens cameras

This paper was published in OPTICS EXPRESS and is made available as an electronic reprint with the permission of OSA. The paper can be found at the following URL on the OSA website: http://dx.doi.org/10.1364/OE.20.027691 . Systematic or multiple reproduction or distribution to multiple locations via electronic or other means is prohibited and is subject to penalties under lawTo obtain 3D information of large areas, wide angle lens cameras are used to reduce the number of cameras as much as possible. However, since images are high distorted, errors in point correspondences increase and 3D information could be erroneous. To increase the number of data from images and to improve the 3D information, trinocular sensors are used. In this paper a calibration method for a trinocular sensor formed with wide angle lens cameras is proposed. First pixels locations in the images are corrected using a set of constraints which define the image formation in a trinocular system. When pixels location are corrected, lens distortion and trifocal tensor is computed.This work was partially funded by the Universidad Politecnica de Valencia research funds (PAID 2010-2431 and PAID 10017), Generalitat Valenciana (GV/2011/057) and by Spanish government and the European Community under the project DPI2010-20814-C02-02 (FEDER-CICYT) and DPI2010-20286 (CICYT).Ricolfe Viala, C.; Sánchez Salmerón, AJ.; Valera Fernández, Á.

Parkfield

En un mundo post pandemia, la forma en cómo la sociedad se relaciona y en cómo las empresas desarrollan sus actividades han tenido un cambio drástico. Tendencias como el cuidado del medio ambiente, vida saludable, entre otros, han venido creciendo con mayor intensidad ante la coyuntura actual. Ante este panorama, y en la búsqueda constante de ideas de negocios sostenibles, nace Parkfield. Parkfield, es una startup que utiliza el concepto de economía circular para que personas que cuenten con un espacio disponible en su casa o local comercial, alquilen a personas que utilicen como medio de transporte una bicicleta o scooter. Para poner en marcha este modelo de negocio se realizaron tanto investigaciones cualitativas como cuantitativas para ver la probabilidad de éxito o fracaso que esta startup podría tener. Como resultado y luego de una inversión inicial de XXX, se concluye que es una empresa con mucho potencial de mercado y sobre todo con una gran escalabilidad. Pero, como todo emprendimiento disruptivo, es fácil de copiar.As the Covid-19 Pandemic stroke in 2020, a massive adoption of bikes and electric scooters occurred in Lima, the most populated city of Peru. People saw these alternatives as healthy and efficient means of transport that could prevent covid infection and avoid bottlenecks in the main avenues, where normally citizens would spend hours to transport across the city as its bus lines and one-line train system can’t handle the demand. Actual data indicates that nearly 3% of the city is moving through the city with a bike or scooter and the trend indicates it will continue to rise, not only because to evade the traffic jams but also for its positive impact on public health and the environment. However, the city is facing a security issue: a huge wave of thefts and robbery has been unleashed. Surveys indicate that it has become the most important topic of concern to solve in the city. For that reason, many bike and scooter users refuse to leave the park outside, “even if you lock your bike to a post there is a huge fear of my bike being stolen” – that is what most users feel. To solve that problem, we have created Parkfield. This app is made to give bike and scooter users a safe and decentralized space where they can park, while on the other side, many families and small local businesses could earn extra revenue streams as they monetize unused areas.Trabajo de investigació

La reflexión sobre los eventos notables de las prácticas clínicas del alumnado de Enfermería Comunitaria II de la Universidad de Zaragoza

Suele decirse que la Enfermería es una profesión vocacional o de “vocación laica”. La motivación hace que contemos con un alumnado abierto a la innovación. Este contexto ha favorecido que el profesorado hayamos introducido nuevas propuestas de enseñanza-aprendizaje como son las del aprendizaje activo, el aprendizaje en espiral y los estudios de caso, entre otros. Hace cuatro años exploramos “los momentos de cuidados” o “eventos notables” de sus prácticas clínicas, es decir, aquellos momentos que más recordaban en positivo o en negativo a partir del “cuidado compartido”..

Página web aprendo ABC

Desde la llegada del covid-19 surgieron grandes cambios para la sociedad, cuidarse y cuidar a nuestros familiares se hizo una prioridad en nuestra vida diaria. Ante ello surgieron distintas estrategias para que las personas no tengan que salir de casa y exponerse al virus, el trabajo en algunas empresas se modificó para que sea de forma remota, los negocios pasaron a ser virtuales y la educación paso ser dictada a distancia con distintos métodos, ya sea por televisión, radio o de forma virtual por distintas plataformas. El Ministerio de Educación desarrollo el programa “Aprendo en casa” con esta estrategia se pretendía que los alumnos tanto de nido, inicial, primaria y secundaria logren seguir sus estudios previos. Sin embargo, para los niños menores de siete años este método no sirvió porque ellos al ser pequeños y estar en pleno desarrollo tienden a distraerse con mayor facilidad y no logran retener la información a largo plazo. Es por ello, que nace la idea de “Aprendo ABC”, la cual tiene como principal objetivo dar solución a dicha problemática. El proyecto de Aprendo ABC consiste en demostrar la viabilidad de crear una página web que brinde reforzamiento mediante juegos didácticos, en donde el niño aprenderá mientras juega, esto está dirigido a menores de 4 a 7 años de Lima Metropolitana. En el desarrollo de esta investigación se logró identificar que los niños no pueden llevar las clases de forma virtual sin un reforzamiento previo. Para obtener datos concisos se tuvo que segmentar, evaluar nuestros costos, quienes son nuestros competidores, nuestros socios clave, entre otros. Asimismo, el desarrollo del plan financiero nos permitió determinar con mayor exactitud si nuestro proyecto es factible y en cuanto tiempo recuperamos nuestra inversión.Since the arrival of covid-19, great changes have arisen for society, taking care of ourselves and our relatives became a priority in our daily lives. Given this, different strategies emerged so that people do not have to leave home and be exposed to the virus, work in some companies was modified to be remote, businesses became virtual, and education happened to be dictated remotely with different methods, either by television, radio or virtually by different platforms. The Ministry of Education developed the program "I learn at home" with this strategy it was intended that students both nests, initial, primary, and secondary can continue their previous studies. However, for children under seven years of age this method did not work because they are small and in full development tend to be distracted more easily and fail to retain information in the long term. That is why the idea of "Aprendo ABC" was born, which has as its main objective to solve this problem. The Aprendo ABC project consists of demonstrating the feasibility of creating a website that provides reinforcement through didactic games, where the child will learn while playing, this is aimed at children from 4 to 7 years of Metropolitan Lima. In the development of this research, it was possible to identify those children cannot take classes virtually without prior reinforcement. To obtain concise data we had to segment, evaluate our costs, who are our competitors, our key partners, among others. Also, the development of the financial plan allowed us to determine more accurately if our project is feasible and how long we recover our investment.Trabajo de investigació
