- Due to aggressive urbanization (with population size), waste increases exponentially, resulting in environmental damage. Even though it looks challenging, such an issue can be controlled if we can reuse them. To handle this, in our work, we design a machine learning and blockchain-oriented system that identifies thewaste objects/products and recommends to the user multiple ’Do-It-Yourself’ (DIY) ideas to reuse or recycle. Blockchain records every transaction in the shared ledger to enable transaction verifiability and supports better decision-making. In this study, a Deep Neural Network (DNN) trained on about 11700 images is developed using ResNet50 architecture for object recognition (training accuracy of 94%).We deploy several smart contracts in the Hyperledger Fabric (HF) blockchain platform to validate recommended DIY ideas by blockchain network members. HF is a decentralized ledger technology platform that executes the deployed smart contracts in a secured Docker container to initialize and manage the ledger state. The complete model is delivered on a web platform using Flask, where our recommendation system works on a web scraping script written using Python. Fetching DIY ideas using web-scraping takes nearly 1 second on a desktop machine with an Intel Core-i7 processor with 8 cores, 16 GB RAM, installed with Ubuntu 18.04 64-bit operating system, and Python 3.6 package. Further, we evaluate blockchain-based smart contracts’ latencies and throughput performances using the hyperledger caliper benchmark. To the best of our knowledge, this is the first work that integrates blockchain technology and deep learning for the DIY recommender system.

Forskningsöversikt (refereegranskat)abstract
- Three-dimensional printing (3DP) is emerging as an innovative manufacturing technology for biomedical and pharmaceutical applications, since the US FDA approval of Spritam as a 3D-printed drug. In the present review, we have highlighted the potential benefits of 3DP technology in healthcare, such as the ability to create patient-specific medical devices and implants, as well as the possibility of on-demand production of drugs and personalized dosage forms. We have further discussed future research to optimize 3DP processes and materials for pharmaceutical and biomedical applications. Cohesively, we have put forward the current state of active patents and applications related to 3DP technology in the healthcare and pharmaceutical industries including hearing aids, prostheses, medical devices and drug-delivery systems.

Education in vascular surgery : critical issues around the globe-training and qualification in vascular surgery in Europe

Tidskriftsartikel (refereegranskat)abstract
- In 1958, the Union Européene des Médecins Spécialistes (UEMS), or European Union (EU) of Medical Specialists the European Union, was founded by the professional organizations of medical specialists in Europe. Among the objectives of the UEMS are to promote the highest level of patient care in the EU and to promote the harmonization of high-quality training programs within the various specialities throughout the EU. Within the 38 Specialist Sections of the UEMS are the European Boards, which are the working groups of the Specialist Sections. In 2005 Vascular Surgery was recognized as a separate and independent Section, a monospecialty, within the UEMS. The efforts of the UEMS are directed at facilitating the free exchange of training and work of trainees and medical specialists between EU countries. This situation, in combination with large differences in requirements and length of training in vascular surgery within the EU, stresses the importance of harmonization in training and certification in vascular surgery within the EU. For that reason, the European Board of Vascular Surgery has organized voluntary examinations yearly since 1996. The candidates who pass qualify as "Fellow of the European Board of Vascular Surgery" (FEBVS) since 2005. The first part of the examination evaluates the eligibility of the candidate (Certificate of Completion of Specialist Training, training center, logbook). The second part is a viva voce assessment that includes (1) case analyses, (2) a review of a scientific article, (3) an overall assessment, (4) a technical skills, and (5) an endovascular skills assessment. To pass the examination, the candidates must achieve a 67% success rate in each part of the examination. During the last 10 years, approximately 75% of the candidates have successfully taken the examination. In the near future the Section and Board, in close collaboration with the vascular societies in the EU, will develop a European vascular surgical syllabus and curriculum that will further harmonize and professionalize the training and certification of vascular surgery in Europe.
