Hand-developed creative prototyping. Methodological proposal and experimentation
The generation of original and innovative ideas is a challenge for any professional. There are several studies that demonstrate how the capacity to explore creativity is reduced until reaching educational levels where it is hardly experienced, and for this reason it is necessary to introduce it in the classroom to complement their academic training before their incorporation into the labour market. The use of new technologies implies in turn an abandonment of manual or craft skills, losing in this area a very relevant possibility of creative development. Most of the methods that are usually used to generate ideas are related to oral and written conceptualization, but manual ideation is practically not contemplated. This study proposes a methodology for generating ideas based on traditional ideation from the physical creation of models as part of the creative process. This methodology has been used with satisfactory results in 38 courses at the Industrial Organisation School (Spain), with 382 people between 18 and 30 years of age participating in the study, demonstrating that the development of creative skills obtained through this new approach can have a very significant impact on students' later career development.This research did not receive any specific grant from funding agencies in the public, commercial or not-for-profit sectors
Análisis de los sistemas actuales en oftalmología para el estudio de enfermedades relacionadas con la modificación geométrica de la arquitectura corneal
[ES] El análisis de la morfología corneal es un procedimiento muy útil en el diagnóstico clínico de determinadas patologías oculares, especialmente las relacionadas con alteraciones ectásicas corneales. Desde la aparición de los sistemas basados en Discos de Plácido a los sistemas que incorporan la fotografía Scheimpflug, existe una variedad de instrumentos que ofrecen la posibilidad de analizar con gran precisión parámetros de la morfología corneal. En esta comunicación se revisan los diversos instrumentos que han sido utilizados para caracterizar la morfología corneal, estando todos influenciados, en mayor o menor medida, por factores como la rapidez de adquisición de datos y la estabilidad de la película lagrimal.

The analysis of the corneal shape is a very useful process that permits the clinical diagnosis of determined ocular pathologies, especially those related with corneal ectatic disorders. From the appearance of the systems based on the Placido-disc technology to the new systems that combine the accurate Scheimpflug photography, there are a variety of ophthalmic instruments that permit to analyze with high accuracy some parameters of the corneal shape. This communication reviews the different systems that have been used to characterize the corneal morphology, being all of them influenced, to a greater or lesser extent, by factors such as the speed for data acquisition and the stability of the tear film.Centro Universitario de la Defensa.

Geometric modelling of the human cornea: A new approach for the study of corneal ectatic disease. A pilot investigation
The aim of this study was to describe the application of a new bioengineering graphical technique based on geometric custom modelling capable to detect and to discriminate small variations in the morphology of the corneal surface. A virtual 3D solid custom model of the cornea was obtained employing Computer Aided Geometric Design tools, using raw data from a discrete and finite set of spatial points representative of both sides of the corneal surface provided by a corneal topographer. Geometric reconstruction was performed using B-Spline functions, defining and calculating the representative geometric variables of the corneal morphology of patients under clinical diagnosis of keratoconus
Assessment of the association between In vivo corneal morphogeometrical changes and keratoconus eyes with severe visual limitation
Assessing changes suffered by the cornea as keratoconus progresses has proven to be vital for this disease diagnosis and treatment. 'is study determines the corneal biometric profile in eyes considered as affected by keratoconus (KC) showing severe visual limitation, by means of in vivo 3D modelling techniques. 'is observational case series study evaluated new objective indices in 50 healthy and 30 KC corneas, following a validated protocol created by our research group, which has been previously used for diagnosis and characterization of KC in asymptomatic (preclinical) and mild visually impaired eyes. Results show a statistically significant reduction of corneal volume and an increase of total corneal area in the severe KC group, being anterior and posterior corneal surfaces minimum thickness points the best correlated parameters, although with no discrimination between groups. Receiving operator curves were used to determine sensitivity and specificity of selected indices, being anterior and posterior apex deviations the ones which reached the highest area under the curve, both with very high sensitivity (96.7% and 90%, respectively) and specificity (94.0% and 99.9%, respectively). 'e results suggest that once severe visual loss appears, anterior corneal topography should be considered for a more accurate diagnosis of clinical KC, being anterior apex deviation the key metric discriminant. 'is study can be a useful tool for KC classification, helping doctors in diagnosing severe cases of the disease, and can help to characterize corneal changes that appear when severe KC is developed and how they relate with vision deterioration.This publication has been carried out in the framework of the Thematic Network for Cooperative Research in Health (RETICS) reference number RD16/0008/0012 financed by the Carlos III Health Institute-General Subdirection of Networks and Cooperative Investigation Centers (R&D&I National Plan 2013–2016) and the European Regional Development Fund (FEDER)
Efficacy of morpho-geometrical analysis of the corneal surfaces in keratoconus disease according to moderate visual limitation
The cornea is a complex hemispheric structure, made of collagen fibres that provide it a homogenous and stable geometry. During keratoconus disease, a loss of tenacity takes place in the collagen fibres that form the corneal structure, producing an alteration of its geometry, this is, a change of its curvature, and therefore, a loss of visual quality of patients. The geometric characterization of the hemispheric structure by means of biometric parameters is a very solid technique of diagnosis, based in a virtual 3D model, which has already been validated for several degrees of severity of keratoconus pathology. In this prospective comparative study, 93 corneas (50 healthy subjects and 43 patients with keratoconus with moderate visual limitation) were geometrically modelled. The results obtained in this work suggest that the best predictive biometric parameters are anterior corneal surface area and posterior apex deviation, and that the strongest correlation is produced between sagittal plane apex area in minimum thickness point and sagittal plane apex area. The studied biometric parameters have shown significant differences between groups. Therefore, the analysis of the biometric parameters that register the geometric decompensation that locally appear in a corneal region, as a response to the asymmetry produced during the development of keratoconus disease with a moderate visual impairment, is a new approach that may lead to a better understanding of the disease with this degree of optical limitation.This publication has been carried out in the framework of the Thematic Network for Co-Operative Research in Health (RETICS) reference number RD16/0008/0012 financed by the Carlos III Health Institute-General Subdirection of Networks and Cooperative Investigation Centres (R&D&I National Plan 2013-2016) and the European Regional Development Fund (FEDER)
