Simulación del servicio al usuario para determinar el nivel de atención en plataforma de la Universidad Privada Antenor Orrego - Trujillo
La presente investigación consiste en desarrollar la simulación del servicio al
usuario en la Plataforma de Atención al Usuario de la Universidad Privada
Antenor Orrego mediante su representación en un diagrama lógico, y de esta
manera determinar el nivel de atención a través de un análisis estadístico para
su correspondiente interpretación. La metodología utilizada fue la simulación
de procesos aplicando el Software Arena para el procesamiento de datos. El
diseño de la investigación es no experimental de una sola casilla y de tipo
descriptiva transversal, utilizando como población la totalidad de los trámites
realizados dentro de la universidad, de los cuales se extrajeron como muestra
aquellos realizados en la Plataforma de Atención. Luego de representar el
servicio en un diagrama lógico y de simularlo a través del Software, se pudo
evidenciar que los ventanilleros, en su mayoría, presentan saturación superior
al 80% en su tiempo de servicio, lo cual provoca que estén expuestos a una
fatiga constante. La cantidad de usuarios que ingresaron al sistema durante
un periodo de 10 horas fue de 576, siendo atendidos satisfactoriamente 308,
dando lugar a que 268 usuarios aún se encuentren dentro del sistema o se
hayan retirado del servicio antes de ser atendidos.The present investigation consists in developing the simulation of the user
service in the Platform of Attention to the User of the Private University Antenor
Orrego by representing it in a logical diagram, and in this way to determine the
service level through a statistical analysis for its corresponding interpretation.
The methodology used was the simulation of processes applying the Arena
Software for data processing. The design of the research is non-experimental,
single sectioned, and of a transversal descriptive type, using as the population
all the procedures carried out within the university, from which those conducted
out in the Attention Platform were extracted as a sample. After representing
the service in a logical diagram and simulating it through the Software, it was
evident that the servers, for the most part, have saturation greater than 80%
in their service time, which exposes them to constant fatigue. The number of
users who entered the system during a 10-hour period was 576, 308 being
satisfactorily served, resulting in 268 users still queuing inside the system or
having withdrawn from service before being served.Tesi

Propuesta de implementación de la metodología Six Sigma para aumentar la rentabilidad en la empresa Agroindustria Alimentaria Nutriaves E.I.R.L.
RESUMEN
El presente trabajo de investigación se fundamentó en la aplicación de la metodología
Six Sigma en las áreas de producción, mantenimiento y calidad de la empresa Agroindustria
Alimentaria Nutriaves E.I.R.L, con el objetivo de reducir la variabilidad del proceso de
producción de alimento balanceado para animales, buscando disminuir la cantidad de
producto no conforme y por ende, aumentar su rentabilidad. Así mismo, se persiguió
demostrar la importancia de esta metodología de mejora como una estrategia de negocio
para alcanzar el éxito de la empresa utilizando el esquema de DMAMC, donde se definió el
principal problema de la empresa, se midió el proceso, se analizó la causa raíz, se mejoró
dicho proceso y por último se controló el mismo por medio del indicador de porcentaje de
producto no conforme y los gráficos de control estadístico.
Utilizando el diagrama Pareto se pudieron ponderar los principales problemas
encontrados, enfocándose en el análisis del costo de calidad (COQ), es decir, los de mayor
impacto en la rentabilidad de la empresa. Al medir el nivel de sigma del proceso se pudo
determinar que éste se encontraba en un nivel de 2,99 lo que significaba tener 67 611,78
defectos por millón de oportunidades.
Las propuestas de mejora se basaron en la implementación de herramientas del Lean
Manufacturing y de ingeniería industrial lo que permitió eliminar o disminuir actividades que
no generaban valor alguno para la empresa ocasionando una gran insatisfacción en el
cliente.
Implementando dichas mejoras, se logró aumentar el valor sigma del proceso a 3,37
lo que significaba la obtención de 30 744,53 defectos por millón de oportunidades, por lo que
se demuestra cómo esta metodología apoya favorablemente a la empresa traducida en la
satisfacción del cliente.ABSTRACT
The research shown in this thesis is based on the use of the Six Sigma Methdology on
the areas involved in the production process, maintenance and quality of
Agroindustria Alimentaria Nutriaves E.I.R.L.; in order to reduce the process’ variability,
looking to lower the amount of nonconforming product and thereby increase profitability. Also,
it sought to show the importance of this improvement methodology as a business strategy for
achieving success by using the DMAIC improvement cycle, by the use of such tool the main
problem of the company was determined, the process was measured, the root cause was
Analyzed, the process was Improved and lastly controlled through the use of control charts.
By using the Pareto chart, we were able to identify the main problems found in the
production area focused on the analysis of the costs of quality (COQ), that is to say the ones
that had the greatest impact on the profitability of the company. By measuring the level of
sigma of the process we were able to determine that it is in a level of 2,99 which means that
there are 67 611,78 opportunities of defects per million.
The proposals for improvement are based on the implementation of statistical tools, as
well as industrial engineering tools, which will allow eliminating or reducing activities that did
not generate any value for the company, causing a large dissatisfaction on the customers.
By Implementing these improvements, the new sigma value of the process was
established at 3,37 which means 30 744,33 opportunities per million, demonstrating how this
approach supports the company, which is translated into customer satisfaction
Mediación tecnológica para desarrollar la competencia didáctica de futuros docentes de inglés como lengua extranajera
This scientific and technological article summarizes the third phase of the research Hacia un mejoramiento de mi quehacer como docente de inglés: El software educativo un medio para solucionar algunos problemas metodológicos de inglés en docentes en formación. This phase was justified because of the previous ones, where some important aspects of the problem on exploration and description were raised; as well as the design and the architecture of the software, the navigation map and the design of some tasks. The piloting of the initial material gathered relevant information, which let the continuous process of the research go on. The main purpose of this third phase was to design educational software according to the students needs in relation to didactic competence of pre-service English language teachers from the Licenciatura en educación básica con énfasis en inglés (uso) program at Distrital University. The third phase in its initial stage was conceived as a pre-experimental research (Larsen-Freeman, 1997). Later, it was stated that the intention was to propose a software application to be used as a means, not as an end, to develop the didactic competence of the pre-service English language teachers. That was how the research turned over from pre-experimental towards descriptive and interpretative research (Merriam, 1998) as the most appropriate research method. The results of the third phase were: The software ELT (English Language Teaching) the Dit on line platform and the application of tasks to develop the didactic competence.Este artículo, de investigación científica y tecnológica, da cuenta de la tercera fase del proceso de investigación del proyecto Hacia un mejoramiento de mi quehacer como docente de Inglés: El software educativo un medio para solucionar algunos problemas metodológicos de inglés en docentes en formación. En las fases anteriores se había avanzado en la exploración y descripción de la situación problémica, diseñado la arquitectura de un software, el mapa de navegación, algunas interfases de las primeras tareas y realizado pre-pruebas del material, las cuales arrojaron la información que posibilitó continuar con la investigación (Hernández y Rodríguez 2002). El objetivo principal de la tercera fase fue re-diseñar el software acorde con las necesidades manifiestas en torno a la didáctica de los estudiantes de pre-grado de la Licenciatura en Educación Básica con Énfasis en Inglés (uso) de la Universidad Distrital. Para la tercera fase del proyecto de investigación se concluyó que la intención era proponer una alternativa que sirviera como medio, no como fin en sí mismo, para el desarrollo de alguna competencia didáctica en los docentes de inglés en formación. De este modo, vimos que hacer una transición desde el método pre-experimental al descriptivo e interpretativo (Merriam, 1998) era lo más adecuado. Los resultados obtenidos fueron el software ELT (English Language Teaching), la plataforma nu-on line y el uso de la tarea pedagógica Task para desarrollar la competencia didáctica
Isolation, Characterization, and Biotechnological Potential of Native Microalgae From the Peruvian Amazon
The objective of this chapter is to provide scientific information on basic aspects to be taken into account to achieve the successful isolation, biochemical, and molecular characterization and then to evaluate the biotechnological potential of native microalgae of the Peruvian Amazon. Recent investigations reported by our research team has demonstrated that the isolated native microalgae from the Peruvian Amazon have a great potential for the biotechnological production of biodiesel and nutraceuticals. This biotechnological potential was identified thanks to the application of various protocols that were standardized by the authors over the last 5 years. In conclusion, the native microalgae of the Peruvian Amazon have biotechnological potential and are therefore promising for the production of both biodiesel and nutraceuticals. Various species of microalgae were identified, isolated, cultured, and characterized using biochemical, nutraceutical, and molecular techniques, the isolation stage being the starting point to achieve various biotechnological applications. Ankistrodesmus sp. is one of the microalgae with potential for the production of biodiesel and microalgae such as Haematococcus pluvialis, Scenedesmus sp., and Chlorella sp., among others demonstrated a high potential for nutraceutical production. The stress conditions to which microalgae are subjected are being a determining factor for the production of biodiesel and nutraceuticals
Modelo prolab: Wawi, un aplicativo que acompaña a los padres de familia en el control, cuidado y seguimiento de sus hijos
El desarrollo infantil es progresivo, continuo, irreversible. Esta etapa es muy
importante y de alto riesgo, ya que durante los primeros 5 años de vida es cuando más se
desarrollan. Es aquí donde radica el principal problema que tienen los padres de familia al no
tener un adecuado control y seguimiento hacia sus menores hijos.
Para esto, se desarrolla un aplicativo móvil, llamado WAWI, que permitirá a los
padres de familia encontrar información sobre salud integrado y enfocado en el seguimiento
percentil, control de vacunas, recomendaciones de alimentación, sueño, estimulación
temprana, lactancia materna, y mediante la Inteligencia Artificial brindará una base de datos
histórica que ayudará a predecir enfermedades nuevas o recurrentes, es decir un super
aplicativo que acompañará al padre de familia a llevar un mejor control y seguimiento de su
menor hijo.
En la deseabilidad de WAWI, según las encuestas realizadas a los padres de familia se
obtuvo que el 74.1% están dispuestos a utilizar el aplicativo. Mientras que la factibilidad fue
validada a través del plan de marketing con una eficiencia de 83.5% al evaluar la relación del
valor tiempo de vida del cliente y su costo de adquisición. Adicionalmente, para la viabilidad
financiera se tomó en cuenta inversión inicial de S/250,000.00 con un VAN financiero
promedio de S/2’384,872 para los cinco primeros años y una tasa de retorno (TIR) de 82%.
Finalmente, en la viabilidad social y ambiental, se estimaron los beneficios y costos
en el ahorro de tiempo en la movilización que le toma al padre en llevar a su hijo a un centro
de salud y ahorro de combustible en el transporte que impacta positivamente en la reducción
de la huella de carbono de esta actividad logrando un VANS de S/3,085,415.69. Asimismo,
WAWI, está alineada a los ODS 2 y 3, generando un mayor impacto en la salud de los niños
menores de 5 años.Child development is progressive, continuous, irreversible. This stage is very
important and high risk, since during the first 5 years of life is when they develop the most.
This is where the main problem that parents have when they do not have adequate control
and follow-up towards their minor children lies.
For this, a mobile application called WAWI is developed, which will allow parents to
find integrated health information focused on percentile follow-up, vaccination control,
feeding recommendations, sleep, early stimulation, breastfeeding, and through the Artificial
Intelligence will provide a historical database that will help predict new or recurring diseases,
that is, a super application that will accompany the father of the family to better control and
monitor his youngest child.
In the desirability of WAWI, according to the surveys carried out with the parents, it
was obtained that 74.1% are willing to use the application. While the feasibility was validated
through the marketing plan with an efficiency of 83.5% when evaluating the relationship
between the customer's lifetime value and its acquisition cost. Additionally, for financial
viability, an initial investment of S/250,000.00 was taken into account with an average
financial NPV of S/2,384,872 for the first five years and a rate of return (IRR) of 82%.
Finally, in the social and environmental viability, the benefits and costs were
estimated in saving time in the mobilization that it takes the father to take his son to a health
center and fuel savings in transportation that positively impacts the reduction of the carbon
footprint of this activity, achieving a VANS of S/1,164,726. Likewise, WAWI is aligned with
SDGs 2 and 3, generating a greater impact on the health of children under 5 years of age

La presente GPC abordó 9 preguntas clínicas, divididas en tres temas: prevención de eventos tromboembólicos, estrategias de control y manejo de FA en emergencias. En base a dichas preguntas se formularon 12 recomendaciones (6 recomendaciones fuertes y 6 recomendaciones condicionales), 29 puntos de buena práctica clínica, y 2 algoritmos. Conclusión. El presente artículo resume la metodología y las conclusiones basadas en evidencias de la GPC para manejo de pacientes con FA en EsSalud.Abstract. This article summarizes the clinical practice guide (CPG) for the management of patients with atrial fibrillation (AF) in the Social Security of Peru (EsSalud). Objective. To provide clinical recommendations based on evidence for the management of patients with AF in EsSalud. Methods. A CPG for the management of patients with AF in EsSalud was developed. To this end, a guideline development group (GDG) was established, including medical specialists and methodologists. The GDG formulated 9 clinical questions to be answered by this CPG. Systematic searches of systematic reviews and ,when it was considered pertinent, primary studies were conducted in Medline during 2017. The evidence to answer each of the posed clinical questions was selected. The quality of the evidence was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology. In periodic work meetings, the GDG used the GRADE methodology to review the evidence and formulate the recommendations, points of good clinical practice, and the flowchart of the CPG. Finally, the CPG was approved with Resolution No. 91 – IETSI – ESSALUD – 2018. Results. This CPG addressed 9 clinical questions, divided into three topics: prevention of thromboembolic events, maintenance therapy and management of AF. Based on these questions, 12 recommendations (6 strong recommendations and 6 weak recommendations), 29 points of good clinical practice, and 2 algorithms were formulated. Conclusion. This article summarizes the methodology and evidence-based conclusions from the CPG for the management of AF in EsSalud
Cutaneous Leishmaniasis and Sand Fly Fluctuations Are Associated with El Nino in Panama
BackgroundCutaneous Leishmaniasis (CL) is a neglected tropical vector-borne disease. Sand fly vectors (SF) and Leishmania spp parasites are sensitive to changes in weather conditions, rendering disease transmission susceptible to changes in local and global scale climatic patterns. Nevertheless, it is unclear how SF abundance is impacted by El Nino Southern Oscillation (ENSO) and how these changes might relate to changes in CL transmission.Methodology and FindingsWe studied association patterns between monthly time series, from January 2000 to December 2010, of: CL cases, rainfall and temperature from Panama, and an ENSO index. We employed autoregressive models and cross wavelet coherence, to quantify the seasonal and interannual impact of local climate and ENSO on CL dynamics. We employed Poisson Rate Generalized Linear Mixed Models to study SF abundance patterns across ENSO phases, seasons and eco-epidemiological settings, employing records from 640 night-trap sampling collections spanning 2000?2011. We found that ENSO, rainfall and temperature were associated with CL cycles at interannual scales, while seasonal patterns were mainly associated with rainfall and temperature. Sand fly (SF) vector abundance, on average, decreased during the hot and cold ENSO phases, when compared with the normal ENSO phase, yet variability in vector abundance was largest during the cold ENSO phase. Our results showed a three month lagged association between SF vector abundance and CL cases.ConclusionAssociation patterns of CL with ENSO and local climatic factors in Panama indicate that interannual CL cycles might be driven by ENSO, while the CL seasonality was mainly associated with temperature and rainfall variability. CL cases and SF abundance were associated in a fashion suggesting that sudden extraordinary changes in vector abundance might increase the potential for CL epidemic outbreaks, given that CL epidemics occur during the cold ENSO phase, a time when SF abundance shows its highest fluctuations
TRY plant trait database – enhanced coverage and open access
Plant traits - the morphological, anatomical, physiological, biochemical and phenological characteristics of plants - determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodiversity conservation, ecosystem and landscape management, restoration, biogeography and earth system modelling. Since its foundation in 2007, the TRY database of plant traits has grown continuously. It now provides unprecedented data coverage under an open access data policy and is the main plant trait database used by the research community worldwide. Increasingly, the TRY database also supports new frontiers of trait‐based plant research, including the identification of data gaps and the subsequent mobilization or measurement of new data. To support this development, in this article we evaluate the extent of the trait data compiled in TRY and analyse emerging patterns of data coverage and representativeness. Best species coverage is achieved for categorical traits - almost complete coverage for ‘plant growth form’. However, most traits relevant for ecology and vegetation modelling are characterized by continuous intraspecific variation and trait–environmental relationships. These traits have to be measured on individual plants in their respective environment. Despite unprecedented data coverage, we observe a humbling lack of completeness and representativeness of these continuous traits in many aspects. We, therefore, conclude that reducing data gaps and biases in the TRY database remains a key challenge and requires a coordinated approach to data mobilization and trait measurements. This can only be achieved in collaboration with other initiatives
