Reform of the bio-separation engineering curriculum under the context of "Emerging Engineering Education" / 生物工程学报

"Bio-separation engineering" is a compulsory course for undergraduate students majored in bioengineering, and an important part of the "emerging engineering education" system for bioengineering. Our teaching team follows the principle of "student development as the center, innovation thinking as the core". Guided by the concept of "learning achievement", we reconstructed the teaching contents of this course, and carried out the teaching reform aiming at solving several long-standing problems. These include, for instance, the theoretical teaching is separated from the experimental practice, and students cannot internalize the theoretical knowledge into practical ability in time. Moreover, the contents of course is out-of-date and out of line with industry demand, the teaching form and assessment methods are relatively single, and the students' professional ability and quality are not effectively cultivated. In the new curriculum system, in which the "online" and "offline" teaching are both applied, we broke the boundary between theoretical and experimental courses, and made the contents keep up with the forefront of industry development through research-based teaching. In terms of teaching methods and teaching evaluation, we made full use of modern information technology to enrich classroom teaching activities, and carried out complete, dynamic and diversified assessment for students. These teaching reform measures greatly improved the students' interest in learning this course, as well as their professionalism and research ability.

El grado de concordancia en el reporte BI-RADS fue bajo en los cuatro centros, con diferencias importantes en el informe y la descripción de los hallazgos. Conclusión. Los centros de imágenes diagnósticas evaluados están habilitados para el funcionamiento, pero se encontraron deficiencias importantes en la calidad de las imágenes y en su lectura, lo que pone de manifiesto la necesidad de establecer estándares de calidad y mejorar los aspectos que se puedan mejorar.

Abstract | Introduction: Mammography quality is directly related to the ability to detect an abnormality and, therefore, quality control is necessary for diagnostic imaging centers. Objective: To evaluate image quality, reading, and mammography service in some diagnostic imaging centers in Manizales, Colombia. Materials and methods: Four diagnostic imaging centers participated voluntarily in the study under confidentiality agreements. Out of 520 women attending the centers, 318 had a mammography. The infrastructure, technology, and human resources of each unit were evaluated based on visual inspections. A radiologist expert in reading and clinical interpretation of mammary images evaluated the quality of the image and the reading. We made the statistical analysis using anova, the kappa index, and the percentage of disagreement. Results: We found images of diminished quality mainly due to the presence of artifacts in 75 % of those evaluated, as well as non-compliance with identification criteria and image labeling. There were difficulties in taking the lateral median oblique projection given the absence of the inframammary. The level of agreement in the BI-RADS reporting was low in the four centers with important differences in the report and description of findings. Conclusion: The city's diagnostic centers under evaluation are authorized for their operation. However, there are important deficiencies in image quality and reading, which highlights the need to seek quality standards starting from those aspects that can be improved upon.

Advances in the simulation of light–tissue interactions in biomedical engineering

Monte Carlo (MC) simulation for light propagation in scattering and absorbing media is the gold standard for studying the interaction of light with biological tissue and has been used for years in a wide variety of cases. The interaction of photons with the medium is simulated based on its optical properties and the original approximation of the scattering phase function. Over the past decade, with the new measurement geometries and recording techniques invented also the corresponding sophisticated methods for the description of the underlying light–tissue interaction taking into account realistic parameters and settings were developed. Applications, such as multiple scattering, optogenetics, optical coherence tomography, Raman spectroscopy, polarimetry and Mueller matrix measurement have emerged and are still constantly improved. Here, we review the advances and recent applications of MC simulation for the active field of the life sciences and the medicine pointing out the new insights enabled by the theoretical concepts.
