In Peru, since the end of the year 1992, there is a mixed retirement model which consists of a public system – integrated by the members of the armed and police forces (Decree Law 19846), public officials (Decree Law 20530), diplomatic officials (Supreme Decree 065-2009-RE) and the National Retirement System (Decree Law 19990) - and, in parallel, a private model, namely, the Private Retirement System (SPP – Sistema Privado de Pensiones) of the Retirement Fund Administrators (AFP – Administradores de Fondos de Pensiones) (Decree Law 25897). Due to the extent that several factors have affected the normal development of the public retirement systems, they have been tried to be replaced by the Chilean private model of 1980. However, the financial crises have revealed that this mechanism also has weaknesses, especially by their intimate connection with the volatility of the fina...

This study presents the design exploration and kinematic validation of a transtibial prosthesis based on a 2SPU-RU parallel mechanism. The prototype is currently at Technology Readiness Level 3 (TRL 3), indicating an early-stage concept that has been evaluated under controlled conditions. The mechanism replicates dorsiflexion–plantarflexion, inversion–eversion, and abduction–adduction, corresponding to ankle motion in the sagittal, frontal, and transverse anatomic planes. The system integrates electric actuators and an ESP32 DevKit V1 microcontroller to control joint movements. Functional tests were conducted to assess kinematic performance using inertial sensors and video tracking. Additional evaluations included force distribution analysis using pressure insoles during dorsiflexion and plantarflexion, as well as energy consumption measurements across gait cycles. While the protot...

This article emerges do the necessity of relocate the relations between science, technological development and the own research. In our country, particularly in the public universities, psychology has oriented its action to the field of technology and the own research. It is ascertained that the transition of the development of scientific psychology has associated to the development of the psychology in the field of professional implementation using for that the own technology of models of intervention, from the clinical, educational or social and organizational field. Nevertheless, it is also recognizable that the production and the generation of systematical knowledge have progressed in a parallel way to the scientific research.

In a previous study using 94 nuclear orthologs, we reported the species status of the Daucus guttatus complex to be unresolved, partitioned into three clades. In the present study, a subset of ten of these 94 orthologs was used to infer the phylogeny of the D. guttatus complex and related species. A near parallel set of accessions, planted in a common garden, was used for morphological analyses. The molecular trees are highly resolved for most of the clades, grouping accessions of the D. guttatus complex into four clades. Bayesian concordance analysis and a coalescent approach gave slightly different topologies. Morphological data likewise support four taxa in the complex. Moreover, herbarium research from a companion study informs nomenclature for taxa of the complex. We identify these four clades as D. bicolor, D. conchitae, D. guttatus, and D. setulosus; internested in or among these ...

This paper presents the first published report of a national-level effort to implement the integrated management of childhood illness (IMCI) strategy at scale. IMCI was introduced in Peru in late 1996, the early implementation phase started in 1997, with the expansion phase starting in 1998. Here we report on a retrospective evaluation designed to describe and analyze the process of taking IMCI to scale in Peru, conducted as one of five studies within the multicountry evaluation of IMCI effectiveness, cost and impact (MCE) coordinated by the World Health Organization. Trained surveyors visited each of Peru’s 34 districts, interviewed district health staff and reviewed district records. Findings show that IMCI was not institutionalized in Peru; it was implemented parallel to existing programmes to address acute respiratory infections and diarrhoea, sharing budget lines and management st...

The abundance of dipoles of glucose in the blood stream would give rise to a pushing out of albumin proteins giving origin to the formation of a biolelectric circuit inside renal glomerulus. In the periods of large amounts of glucose and albumin in blood, kidneys might not be able to filter proteins initializing the interaction protein-protein at the renal glomerulus. From this nephrine and albumin interaction can be seen as a capacitor because the anionic and cationic functions of proteins. This paper have paid attention to the physics of renal glomerulus when it is electrically involved due to the presence of albumin that surpasses the different layers of renal glomeulus becoming a strong indicator of the kidney disease.

El presente trabajo desarrolla un modelo de optimización para el proceso de reabastecimiento en un centro de distribución perteneciente a un operador logístico del sector consumo masivo. La empresa presentaba demoras recurrentes en la entrega de pedidos, ocasionadas principalmente por un reabastecimiento reactivo, la dispersión de productos de alta rotación y la falta de criterios definidos para la asignación de ubicaciones en el primer nivel. Estas deficiencias generaban picking en altura, recorridos excesivos, interrupciones constantes durante el proceso y riesgo de incumplimiento de los acuerdos de nivel de servicio establecidos con el cliente. Para sustentar la magnitud del problema, se analizaron indicadores operativos como tiempos de ciclo, frecuencia de quiebres en ubicaciones de picking y movimientos adicionales relacionados al reabastecimiento.

The Ecuadorian Amazon region is permanently subject to deforestation processes and in parallel to the implementation of agricultural, and livestock management systems that can affect soil quality. This study assessed the effect of different land use types on soil quality using the Integrated Soil Quality Index (SQI) and minimum indicators. To do this, it considers representative soil samples, 4 types of land use, and a productive landscape in the province of Pastaza. The land use types evaluated were sugarcane (SC), agrosilvopastoral System (ASPS) silvopastoral timber system (SSTT), and secondary forest (SF). Land use type had significant effects on some soil properties and, therefore, on soil quality. The soil quality index was developed using BD, Ca+Mg/K, and SOM which had the highest weighting values, suggesting a higher contribution to the final SQI. The Soil...

Abstract — In this project, a design for an automated mechanism is presented for implementation in textile manufacturing processes, where an integrated system for textile fiber recognition based on artificial intelligence (AI) was added. The mechanical design of the machine was studied in terms of force, providing a robust and efficient structure that supports the integration of sensors and cameras for real - time image capture of the processed fibers. Additionally, this design included a precise feeding system and a transport mechanism that ensured the stability and correct positioning of the fibers during analysis. In parallel, an AI model was implemented to identify and classify textile fibers based on their color characteristics. A simulated dataset was generated , where each type of fiber was represented by a specific color (red, green, blue, yellow), and a simple neural network w...

The growing presence of Internet and social networks into the structure of social information and their integration into traditional journalism, give the idea of a shift in the relationship between media and its users, placing them as partners in the development of public agendas. However, the change seems to focus on the activation of parallel information systems, remote from the original proposal of Civic Journalism. The purpose of this paper is to recover the meaning and the original proposals of this current, distinguishing it from functional uses that Internet provides to the media today. At the same time, investigates the model at theoretical and methodological level, rescuing the few cases in the country.
