El presente aporte se circunscribe a uno de los más serios problemas de la criminalística peruana, el abandono de la poroscopia, disciplina abocada al estudio de los poros presentes en la piel. Para ello, se efectuó el estudio de la literatura nacional e internacional que versa sobre la dimensión teórica de esta rama del saber y la evidencia empírica referida a su aplicación. Se concluyó que, el uso de la poroscopia optimizaría la identificación personal, al reducir varios de los equívocos provocados por el empleo aislado de los dos primeros niveles de análisis dactilar, e incrementaría la fiabilidad de las homologaciones, motivos por los que la misma debe ser implementada a nivel nacional.

Twenty seven homing pigeons (10 males and 17 females) were biometrically studied and the bilateral symmetry (right-left) level was evaluated. Analysed traits were the length of outer external rectrices, length of the wing and length of the second primary feather. The aim of the study was to check whether there is a relationship between the degree of asymmetry level and general health of the birds (expressed as a measure of body condition). Measurements showed a normal distribution and without differences according to the body condition, indicating a high degree of stable growth.

Objective. Understand the perspective of patients in relation to the current way of obtaining an appointment in primary health care. Methods. A bibliography search was performed in the online databases in Spanish and English. The main source was sought by reviewing the bibliographical references of the publications. Results. It was found that the shift to virtuality has made it easier for users to access a primary health care appointment, reducing waiting time and paving the way for non-face-to-face care; the level of user satisfaction has increased positively. Conclusions. Phone and virtual requests are here to stay; these are not intended to replace face-to-face requests, but they are a necessary tool to improve the quality of care for users.

This paper is based on the premise that parole assumes the configuration of rights and the objective was to reach an approximation to the implications of such a postulate in the Peruvian legal system. For that purpose, an analysis of the national and international literature that deals with the dogmatic and applicational dimensions of these figures was carried out. It was concluded that it is not possible to restrict the legal application of early release, regardless of the seriousness of the crime or sentence imposed, and that the concession factors to be legislated must be based on empirical evidence related to recidivism.

The present research aimed to examine whether perfectionism and some demographic variables can predict levels of resilience (and their dimensions) in adults from Venezuela. The design was cross-sectional predictive, through logistic regression analysis. Participants were 313 Venezuelan mature adults (M = 46.44 years), mostly women (82.7%), residents of the interior of the country (70.9%), with higher education (64.2%), and paid employment (67.9%). An adapted version of the Multidimensional Perfectionism Scale (Frost et al., 1990) and the Resilience Scale for Adults (Hernández y Lezama, 2016) was applied via Google Forms. Organization was a positive predictor of resilience and two of its dimensions (OR = 1.13 - 1.27), while fear of mistakes was a negative predictor of resilience and “morality and values” (OR = 0.96). Personal standards positively predicted“perseverance and hope” ...

Cancer is the second leading cause of death in Latin America, and the economic cost it requires will increase markedly in future years (1). If nothing is done about it, cancer incidence and mortality in South and Central America will continue to rise sharply between 2012 and 2035 (2). It is expected that by 2030 the incidence of cancer will increase by 32%, reaching 5 million cases per year (1). At the level of Latin America, health policies have been implemented, where they prioritize the feeding of these patients to reduce the sequelae that the treatments can cause, obtaining optimal results (3). It is in this context that the effects of cancer and its treatment make it difficult to meet the nutritional requirements of patients. Chemotherapy is the most widely used medical treatment for cancer in the world. Knowing that cancer cells tend to grow and divide faster than normal cells, thi...

El presente estudio analiza la variación de los parámetros de resistencia de suelos lacustres en Cerro de Pasco ante el incremento de sobrecarga inducido por la construcción progresiva de diques. Para su evaluación se emplearon resultados de ensayos de penetración estándar (SPT) realizados en diferentes años (2010, 2019 y 2025), correspondientes a etapas sin carga y posteriores a la aplicación de cargas de 540 kPa y 620 kPa. Los valores del número de golpes fueron corregidos mediante la metodología (N₁)₆₀ según la norma ASTM D1586, y se determinaron los parámetros geotécnicos derivados: cohesión no drenada (Cu), ángulo de fricción interna (φ), coeficiente de presiones laterales en reposo (K₀), módulo de deformación (Es) y presión admisible (qadm). Los resultados evidencian una reducción progresiva de Cu, Es y qadm a lo largo del tiempo, indicando que la sobre...

El presente trabajo de investigación es un estudio de caso basado en la empresa Industrias Jhomeron SA, una empresa peruana dedicada a la fabricación de pinturas cuyo problema inicia por considerar comprobantes de pago sin validez tributaria e incumplimiento de los requisitos del reglamento de comprobantes en el libro de compras; conllevando así a incurrir en contingencias tributarias producto del cálculo incorrecto del IGV de compras para efectos de deducción del crédito fiscal y gastos para efectos de deducción del Impuesto a la Renta. En ese sentido, la presente investigación tuvo como objetivo demostrar cómo el proceso de validación de comprobantes de pago permite detectar las contingencias tributarias en la empresa Industrias Jhomeron SA. Con el propósito de subsanar voluntariamente las infracciones cometidas y evitar más desembolsos de dinero. El tipo de investigación ...

Most Andean lakes and lagoons are used as reservoirs to manage hydropower generation and cropland irrigation, which, in turn, alters river flow patterns through processes of storage and discharge. The Carhuacocha and Vichecocha lagoons, fed by glaciers, are important aquatic ecosystems regulated by dams. These dams increase the flow of the Mantaro River during the dry season, supporting both energy production and irrigation for croplands. Water quality in the Carhuacocha and Vichecocha lagoons was assessed between storage and discharge events by using the Canadian Council of Ministers of the Environment Water Quality Index (CCME WQI) and multivariate statistical methods. The quality of both lagoons is excellent during the storage period; however, it decreases when they are discharged during the dry season. The most sensitive parameters are pH, dissolved oxygen (DO), and biochemical oxyge...

The objective was to describe the characteristics and nutritional profile of processed foods and beverages advertised during child protection hours (6 am to 10 pm, according to Peruvian regulations) on the two channels with the largest audience on Peruvian television. In this cross-sectional study, 448 hours of television content on 14 random days from 6:00 am to 10:00 pm between January and February 2021 were recorded and 2061 advertisements for processed foods and beverages were identified. The time frame with the most publicity for these foods was between 2:00 pm. and 6:00 pm. (33,9%). The most advertised categories were beverages (41,7%) and confectionery (17,8%). 46,9% of foods exceeded at least one of the technical parameters evaluated in the first stage of the Peruvian law (total sugar, saturated fat, or sodium) and 88,4% would do so in the second stage. The majority of advertised...

La presente Investigación titulada “La Cultura Tributaria y su Incidencia en la Evasión Fiscal del Sector Imprenta” tiene como objetivo determinar cómo la cultura tributaria incide en el aumento de la evasión fiscal del Sector Imprenta del Cercado de Lima, Perú. La finalidad es demostrar cómo la falta de conocimientos en temas tributarios incide en la evasión fiscal por la despreocupación de los contribuyentes que no le dan el valor necesario al cumplimiento de sus obligaciones, a pesar, que la administración tributaria hace grandes esfuerzos para que éstos cumplan. Sin embargo, dichos esfuerzos no están orientados a que la contribución tributaria sea considerada amigable, sino que sea percibida como un fantasma que provoca terror en los contribuyentes. Para esta investigación se empleó la Metodología y la técnica de recolección de información. Para ello se elaboró...
