1 archivo PDF (153 páginas)Con este segundo tomo de este título, renace el espíritu de un proyecto académico del Grupo de Investigación DeiGmas que busca promover el diálogo entre la comunidad del diseño, en torno a la construcción de conceptos disciplinarios propios. El valor esencial de la presente publicación radica en que ofrece a los lectores una conjunción de ideas de profesionales experimentados en diversas especialidades del diseño industrial, sustentadas en su experiencia concreta del quehacer cotidiano en organizaciones nacionales de distinta índole

Lo glocal y el turismo. Nuevos paradigmas de interpretación.

El estudio del turismo se realiza desde múltiples escalas y enfoques, este libro aborda muchos temas que es necesario discutir desde diversas perspectivas; es el caso de la reflexión sobre la propia disciplina y sus conceptos, así como los asuntos específicos referidos al impacto territorial, los tipos de turismo, las cuestiones ambientales, el tema de la pobreza, la competitividad, las políticas públicas, el papel de las universidades, las áreas naturales protegidas, la sustentabilidad, la cultura, el desarrollo, la seguridad, todos temas centrales documentados y expuestos con originalidad y dominio del asunto. Lo multiescalar es básico para la comprensión del sistema turístico, sistema formado de procesos globales, regionales y locales. El eje de discusión del libro es lo glocal, esa interacción entre lo nacional y local con lo global

ViDa1: The Development and Validation of a New Questionnaire for Measuring Health-Related Quality of Life in Patients with Type 1 Diabetes

IGTPAltres ajuts: Funding was provided by the Canarian Agency for Research,Innovation and Information Society (ACIISI) (DA predoctoralfellowship TESIS20120050) and the V Guido Ruffino Grantfor Research in Therapeutic Education for Diabetes (SpanishDiabetes Society 2015)This study describes the development of a new questionnaire to measure health-related quality of life (HRQoL) in patients with type 1 diabetes (the ViDa1 questionnaire) and provides information on its psychometric properties. For its development, open interviews with patients took place and topics relevant to patients' HRQoL were identified and items were generated. Qualitative analysis of items, expert review, and refinement of the questionnaire followed. A pilot study (N = 150) was conducted to explore the underlying structure of the 40-item ViDa1 questionnaire. A Principal Component Analysis (PCA) was performed and six of the items that did not load on any of the factors were eliminated. The results supported a four-dimensional structure for ViDa1, the dimensions being Interference of diabetes in everyday life, Self-care, Well-being, and Worry about the disease. Subsequently, the PCA was repeated in a larger sample (N = 578) with the reduced 34-item version of the questionnaire, and a Confirmatory Factor Analysis (CFA) was performed (N = 428). Overall fit indices obtained presented adequate values which supported the four-factor model initially proposed [(2(df =554) = 2601.93) (p < 0.001); Root Mean Square Error of Approximation = 0.060 (CI = 0.056 −0.064)]. As regards reliability, the four dimensions of the ViDa1 demonstrated good internal consistency, with Cronbach's alphas ranging between 0.71 and 0.86. Evidence of convergent-discriminant validity in the form of high correlations with another specific HRQoL questionnaire for diabetes and low correlations with other constructs such as self-efficacy, anxiety, and depression were presented. The ViDa1 also discriminated between different aspects of clinical interest such as type of insulin treatment, presence of chronic complications, and glycemic control, temporal stability, and sensitivity to change after an intervention. In conclusion, the ViDa1 questionnaire presents adequate psychometric properties and may represent a good alternative for the evaluation of HRQoL in type 1 diabetes

Escuela inclusiva y subjetividad, categorías para el desarrollo del talento en niños y niñas

Introduction. The current times in Colombian education indicate that the curriculum and the school must be articulated to the universal context of knowledge and consider human condition as a crucial factor in the pedagogy practice. Objective. Establish, with an integrated look, the potential and the talent of the students in the classroom. Materials and methods. This research work has been made with a qualitative method, educational action research. The technique has been defined keeping in mind its intention: the biographic method from its variations: biography and assisted autobiography, chosen to determine the research's finds. Results. The biographic method brought recognition and self-recognition from parents to children, from students to themselves and from teachers to students, and unveils perceptible talents of the students in the classroom. Besides, the pedagogy practice of pertain re-creation is determined. Conclusion. The whole population recognized human condition from its potential, with the self-recognition of their capabilitiesIntrodução.

O método biográfico deu lugar ao reconhecimento e auto-reconhecimento dos pais de família para seus filhos, os estudantes para si mesmos e dos professores para seus estudantes, e deixa à luz os talentos perceptíveis dos estudantes em classe; ademais, determina com isso a prática pedagógica a recriar pertinentemente. Conclusão. Se obteve um total da população que deu lugar ao reconhecimento da condição humana desde suas potencialidades a partir do auto-reconhecimento das suas capacidades.Introducción.

Control of mycotoxigenic fungi with microcapsules of essential oils encapsulated in chitosan

Abstract Aspergillus and Fusarium are the fungi genera most frequently isolated from cereal grains and other commodities. They are capable of producing mycotoxins, which can affect the human and animal health. Synthetic fungicides have been used to control these fungi, nevertheless, they have acquired resistance and other alternatives are necessary since they now need higher amounts. Therefore, the aim of this study was to evaluate the efficacy of cinnamon, clove and thyme essential oils (EOs) alone and encapsulated in chitosan on the radial growth, spore germination and mycotoxin production by Fusarium verticillioides and Aspergillus parasiticus. The composition of the EOs was determined by gas chromatography mass spectrometry (GC-MS). EOs inhibited radial growth and spore germination of both fungal species better than when they were encapsulated, plus, they reduced mycotoxin production. The major components were eugenol in cinnamon and clove EO (70 and 63%, respectively) and 2-methyl-5-(1-methyethyl)-phenol (46.2%) in thyme EO. The microparticles with clove and thyme EO showed good surface charges, higher than +30 mV and their average size for the three types of microparticles was about 750 nm. Our findings suggest that EOs both alone and encapsulated in chitosan have a fungistatic effect on Fusarium verticillioides and Aspergillus parasiticus

Donated Blood Screening for HIV, HCV and HBV by ID-NAT and the Residual Risk of Iatrogenic Transmission in a Tertiary Care Hospital Blood Bank in Puebla, Mexico

Hepatitis C virus (HCV), human immunodeficiency virus (HIV) and hepatitis B virus (HBV) can be transmitted by blood transfusion. Most transmission occurs during the acute viremic phase (AVP), before antibody development. To reduce transmission risk, individual donor nucleic acid testing (ID-NAT) is used. In Puebla, Mexico, serological tests and ID-NAT have been applied to screen blood donors and detect individuals in AVP. In the present study, 106,125 blood donors’ data in two periods (2012–2015 and 2017–2019) were analyzed. The residual risk (RR) values were calculated considering ID-NAT results. The RR for HIV was 14 in 1 million donations or 1 in 71,428, the RR for HVC was 6.8 in 1 million donations or 1 in 147,058 and, for HBV, it was 156 in 1 million donations, or 1 in 6410. Previously, it was predicted that the transmission RR of these viruses would be reduced in Mexico through better screening with NAT. The use of ID-NAT has, indeed, increased the safety of blood reserves for HIV and HCV. However, more research is needed to determine why the residual risk of HBV did not decrease as much over the study period. ID-NAT is an important complementary tool for blood donor screening that should be implemented
