For companies operating within the garment manufacturing industry, having frequent downtimes in their production flows is an extremely common issue. In this context, a balanced production line is required to prevent high waiting times due to limited productive capacity. A well-balanced assembly line allows products to be produced in an optimum time while using less resources, such as machines, materials, or labour, since the right number of products is produced with the exact amount of resources, thus generating savings in production costs. This paper seeks to foster optimum resource allocation through the line balancing tool. Finally, to define a work methodology, best practices were selected, and a procedures manual was developed focusing on Standardization. Both tools were implemented after implementing changes to the company culture by means of the Employee Empowerment tool. As a res...

INTRODUCCIÓN: La coledocolitiasis es una complicación frecuente de la litiasis vesicular. La pancreatocolangiografía retrógrada endoscópica (PCRE) es el “gold standard” para su diagnóstico y tratamiento, sin embargo debido a su significativa morbilidad y mortalidad, otros métodos diagnósticos han sido planteados, tales como la colangiografía intraoperatoria (CIO) y la colangioresonancia (CRMN) , reservando a la PCRE sólo para fines terapéuticos. OBJETIVOS: Verificar la utilidad de los predictores de coledocolitiasis descritos en la literatura MATERIAL Y MÉTODOS: Estudio correlacional, observacional, transversal prospectivo que se realizó entre agosto del 2004 y enero del 2005 en el Hospital Arzobispo Loayza. Conocidos criterios clínicos, bioquímicos y ecográficos predictores de coledocolitiasis fueron analizados en 151 pacientes sometidos a PCRE. Usando análisis univ...

INTRODUCCIÓN: La investigación biomédica en el Perú es limitada. Entre los factores implicados en este problema tenemos el reducido gasto per-cápita en investigación, los esfuerzos dispersos y la escasa comunicación entre la investigación y las actividades sociales y productivas. OBJETIVOS: Determinar los factores personales, laborales y académicos relacionados con la producción científica de los médicos gastroenterólogos que laboran en Lima provincia. MATERIAL Y MÉTODOS: Estudio correlacional, observacional, comparativo, transversal y retrospectivo que se realizó entre marzo del 2007 y abril del 2008. Se elaboró una encuesta conteniendo las variables de investigación, la cual se aplicó autoadministada a los gastroenterólogos. Usando análisis bivariado y multivariado, se identificaron factores relacionados con la producción científica de los gastroenterólogos. RESU...

In order to know the effect of 60Co gamma irradiation, in the sunflower crop, were irradiated achenes in the Transelektro LGI-01 in the Instituto Nacional de Investigaciones Nucleares. The data was evaluated under a completely randomized design, where the treatments were 0, 100, 200, 300, 400, 500, 600, 700, 800 and 900 Gy and four repetitions (10x4) = 40 experimental units. The response variables were: plant height, root length and volume, dry biomass. The results indicated that germination and sprouting decreased as the radiation increased, adjusting these to a quadratic model. Plant height, length, root volume and dry biomass decreased at high doses. From this investigation it was concluded, that doses of 100 and 200 Gy, have a stimulating effect on plant height and root length, being an important agent, to induce genetic variability in sunflower.

Local therapies are increasingly used for ocular preservation in retinoblastoma. In middle-income countries, these techniques pose specific challenges mostly related to more advanced disease at diagnosis. The Grupo de America Latina de Oncología Pediátrica (GALOP) developed a consensus document for the management of conservative therapy for retinoblastoma. Intra-arterial chemotherapy (OAC) is the preferred therapy, except for those with less advanced disease or age younger than 6 months. OAC allowed for a reduction in the use of external beam radiotherapy in our setting. Intravitreal chemotherapy is the preferred treatment for vitreous seeding. Enucleation is the treatment of choice for eyes with advanced disease. © 2023 Wiley Periodicals LLC.

Objective. To report the progress in Peru, since June 2019, in the implementation of the World Health Organization Global Initiative for Childhood Cancer using the CureAll framework, which can be replicated in low- and middle-income countries. Methods. A mixed method was used of participatory and documentary evaluation. The participatory evaluation included stakeholders from various government institutions, nonprofit organizations, and international partners. The documentary aspect consisted of a review of data on the regulatory environment, national projects, and interventions implemented. The Ministry of Health engaged more than 150 participants to form working committees, which have developed policy and regulatory documents to strengthen care services. Results. Achievements include a decrease in the national treatment abandonment rate from 18.6% to 8.5%, the approval of the Childhood ...
