Grigore T. Popa University of Medicine and Pharmacy, Faculty of Medical Bioengineering, Iasi, Romania 2 Institute of Computer Science of Romanian Academy, Iasi Branch E-mail: [email protected] Abstract—The existence of so many terrible and incurable diseases, among which cardiovascular, neurodegenerative and psychic diseases, cancers, even a newcomer – obesity – emphasizes the permanent need of very skilled staff in health care. Besides medical and pharmacy specialists, the engineering branch has a main role in modern health care, characterized by high medical technology, powerful software programs for data analysis, and top management tools to increase efficiency of the health care system. Among many engineering specialties, bioengineers and biomedical engineers, even if somehow different, have a main common feature: the strong inter-, multiand transdisciplinarity of their work. The paper analyses some characteristics of the specific education process in both fields, shows their sub-domains of activity, presents opportunities related to designing a career, presents specific aspects of 20 years of medical bioengineering education in Iasi city, Romania, and concludes that medical bioengineering and biomedical engineering belong to the top jobs, with a constant growths in demand, and are highly appreciated jobs, mainly in western countries. Keywords: education, bioengineering, biomedical engineering, career development.

I. INTRODUCTION Two definitions refer to our topics: (i) “Bioengineering (BE), which integrates physical, chemical, mathematical, and computational sciences and engineering principles to study biology, medicine, behavior, and health. It advances fundamental concepts, creates knowledge from the molecular to the organ systems levels, and develops innovative biologics, materials, processes, implants, devices, and informatics approaches for the prevention, diagnosis, and treatment of disease, for patient rehabilitation, and for improving health.” (NIH, USA, Working Definition of Bioengineering - July, 1997, [1]). In other words, BE is a relatively new and vast branch of engineering in which the engineering principles are applied to define and solve problems in biology and medicine. It is basic

research oriented activity carried out using tools and principles of the physical sciences to develop a better understanding of biological systems. BE is the application of engineering principles to living structures, such as creating artificial organs, medical devices, chemicals, drugs and tissues. BE includes the study of cellular engineering, tissue engineering, cell signaling, cell imaging, bioinformatics, molecular engineering, bioacoustics, biomaterials, genetic engineering etc. Examples of the concrete applications of the BE are sequencing of eukaryotic genome, creation of the anterior crucial ligament and study of the effects of zero gravity on mechanical signal transduction pathways of bone cells, creation of artificial organs, creation of biosensors by using biomembranes and genetic modification of plants and microorganisms. (ii) Biomedical engineering (BME) is the application of engineering principles and design concepts to medicine and biology for healthcare purposes (e.g. diagnostic, therapeutic or preventive). This domain seeks to close the gap between engineering and medicine, i.e. combines the design and problem solving skills of engineering with medical and biological sciences to advance healthcare treatment, including diagnosis, monitoring, and therapy. It is multidisciplinary, i.e. brings together concepts from different branches of engineering like electrical, mechanical, chemical and computer science. Prominent examples are biomedical devices and instrumentation, biomechanics and biotransport, biomaterials, biomedical optics, neural engineering, etc. A concrete application of the BME is the development and manufacturing of biocompatible prostheses like prosthetic eye, which uses principles of the mechanical, electronics and computer engineering, and of the biocompatible materials. Medical devices can be used for the diagnosis, treatment or prevention of the diseases. Medical imaging equipment such as tomography are generally used for the scanning of human body and represent the application of many engineering fields to diagnostic imaging.

The main difference between BE and BME is that BE is a global term which encompasses the BME and it is applied to all life sciences and medicine while BME more focuses on medical domain and healthcare. However, few “stakeholders” adhere strictly to the above definitions and, in practice, the terms are often used interchangeably. A major aim of BE and BME is to provide integrated approaches to the solutions of biological and biomedical problems, mainly for healing and eradicate complex diseases. The general strategy is to provide engineering approaches to enhance the power of the scientific methods, and to maintain a balance between experimental observation and quantitative analyses. While the development of theory and of mathematical models is strongly endorsed, these should be evaluated wherever possible using biological data from experiments that test specific hypotheses. II. MOTIVATION AND EDUCATION IN BE AND BME The U.S. Department of Labor's Occupational Outlook Handbook states that employment opportunities for bioengineers were better and are also expected to grow faster than the average for all occupations in the coming years. In fact, BME is expected to be the fastest-growing job market in the United States during the next seven years, according to the U.S. Bureau of Labor Statistics (BLS) [1]. Between 2010 and 2020, the number of biomedical engineers is projected to rise by about 62 percent in the U.S. [1]. The aging of the population and the focus on health issues will increase the demand for better medical devices and equipment designed by bioengineers. For example, rehabilitation engineering is growing rapidly to meet the increasing needs of aged patients and patients with disabilities. Also, current advances in computer-assisted surgery and molecular, cellular, and tissue engineering designed to minimize patients hospitalization time boost the demand for bioengineers. In May 2013 (updated in April 1, 2014), the same U.S. Bureau of Labor Statistics belonging to the U.S. Department of Labor stated that national estimates for biomedical engineers (a top occupation) reach 19,890 persons (but these estimates do not include many self-employed workers), and their mean hourly/annual wage is $45.18/$93,960, respectively, significantly more than median value of U.S. top salaries [2]. This is a pragmatic motivation for a job in BME. Combined with a continuous growing job market and financial reward, bioengineers and biomedical engineers have the gratification that comes from working to meet the needs of society. They choose the bioengineering field to be of service to people, to be a part of the excitement of working with living systems, and to apply advanced technology to the complex problems of biology and medicine. A.

Typical Job Description

In general, biomedical engineers apply engineering principles and materials technology to healthcare. This can

include researching, designing and developing medical products and services, such as joint replacements or robotic surgical instruments, designing or modifying equipment for clients with special needs in a rehabilitation setting, or managing the use of clinical equipment in hospitals and the community. Biomedical engineers are employed by health services, medical equipment manufacturers, universities and research departments/institutes. Job titles vary depending on the exact nature of the work. As well as biomedical engineer, other terms that are used are bioengineer, design engineer and clinical engineer/scientist (in a hospital setting/clinical situation). The type of activities carried out varies depending on the type of employer and seniority of the post held. Tasks may involve: • using computer software and mathematical models to design, develop and test new materials, devices and equipment. This can involve programming electronics, building and evaluating prototypes, troubleshooting problems, and rethinking the design until it works correctly; • liaising with technicians and manufacturers to ensure the feasibility of a product in terms of design and economic viability; • conducting research to solve clinical problems using a variety of means to collate the necessary information, including questionnaires, interviews and group conferences; • liaising closely with other medical professionals, such as doctors and therapists as well as with end-users (patients and their careers); • discussing and solving problems with manufacturing, quality, purchasing and marketing departments; • assessing the potential wider market for products or modifications suggested by health professionals or others; • arranging / performing clinical trials of medical products; • approaching marketing and other industry companies to sell the product; • writing reports and attending conferences and exhibitions to present their work and latest designs to a range of technical and non-technical audiences; • meeting with senior health service staff or other managers to exchange findings; • dealing with technical queries from hospitals and GPs and giving advice on new equipment; • testing and maintaining clinical equipment; • training technical or clinical staff; • investigating safety-related incidents; • organizing service and maintenance activities of the equipment in hospital; • keeping up to date with new developments in the field, nationally and internationally.

Who Hires Bioengineers?

Manufacturing industries employed 38 percent of all bioengineers, primarily in the pharmaceutical and medicine manufacturing and medical instruments and supplies industries. Others were employed in universities, hospitals, research facilities of education and medical institutions, teaching, governmental regulatory agencies, health assurance companies or as independent consultants. In Europe, Japan and the new emergent countries from Asia, a similar situation occurs, even during a relative economic crisis in which we live. In this respect one may emphasizes that big international companies, like 3M, Boston Scientific, Inc., Eli Lilly, FDA, General Electric Medical Systems, Johnson & Johnson, Medtronics, Merck, NASA, Phillips Medical Systems, Siemens Medical, to cite only few of them, permanently hire bioengineers. C.

General Educational Aspects

Fields of specialization within undergraduate BE and BME programs usually include: Bioinformatics, Bioinstrumentation, Biomaterials, Biomechanics, Biomedical devices, BioMicro/Nano-Electro-Mechanical Systems, Biosignal and biomedical image processing, Biotechnologies, Cellular, tissue and molecular engineering, Clinical engineering, Medical imaging, Medical electronics, Molecular imaging, Rehabilitation engineering. Some universities include healthcare management into the above list of specialties, but the fact is the specific management for healthcare may be studied within different educational programs.

International Associations

Nowadays technology plays a key role in changing the world for the benefit of humanity. IEEE (Institute of Electrical and Electronics Engineers) continues to be a global leader in this scenario. With the extraordinary expertise that IEEE technology-centric communities can offer, those interested can face this challenge and enhance our profession by: (i) Being the trusted source for high-quality innovative and timely knowledge in current, interdisciplinary and novel fields, increasing responsiveness to the needs of scientists, practicing professionals and students, and attracting new communities and the general public; (ii) Promoting inclusive internationalization and preserving diversity of technological expertise, profession, culture, geographical origin, gender, and age, while acting holistically in the evolving international scenarios and nurturing local identities and communities; (iii) Empowering technology-centric communities worldwide by addressing their needs with a human-centered approach, seeking for more networking opportunities through social networks and new media sources, broadly engaging the young generations, and intensifying synergic alliances with local and international associations.

The IEEE is heavily involved in bioengineering through the IEEE Engineering in Medicine and Biology Society (EMBS), which has been active since 1952. The IEEE EMBS publishes both several technical journals like IEEE Transactions on Biomedical Engineering, IEEE Transactions on Neural Systems and Rehabilitation Engineering, and publications oriented towards the general public like IEEE Pulse. From formalized mathematical theory through experimental science, from technological development to practical clinical applications, IEEE EMBS members support scientific, technological, and educational activities as they apply to the concepts and methods of the physical and engineering sciences in biology and medicine. IEEE and EMBS organize every year important and useful scientific events, beginning with the International Conference of the Engineering in Medicine and Biology Society (EMBC). Another very active international association in BE and BME is the Int. Federation of Medical and Biological Engineering (IFMBE), which organizes every 3 years MBEC conferences. Together with the International Organization for Medical Physics – IOMP set up the International Union for Physical and Engineering Sciences in Medicine (IUPESM; www.iupesm.org). IUPESM organizes every 3 years its World Congress, that may be considered the most important scientific event in BE and BME. The European Alliance of Medical and Biological Engineering and Science (EAMBES), founded in 2003, has as main objective to improve the health, wealth, and wellbeing of the citizens of Europe by the application of Medical and Biological Engineering and Science (MBES), to support and promote MBES education, training and accreditation programs, research, development and innovation, and better contacts with industrial companies, also to establish and maintain liaison with national and European governments and agencies. It is noteworthy involvement of two staff members of our faculty, dr. Dan Zaharia and dr. Radu Ciorap, in this top level European association.

Medical Bioengineers who work in hospitals are involved in technical departments for medical equipment manipulation and maintenance, in medical technology management. They are involved in selection of the devices for patient care. These devices vary from simple external components to marvelous imagistic sophisticated equipment that allows physicians to look inside the body. Bioengineers also work carefully to ensure that all of the hospital's equipment is safe and reliable. Some bioengineers work in design and research laboratories in companies for designing monitoring equipment, medical dedicated software, or processes to deliver therapeutic drugs safely and effectively. Rehabilitation bioengineers are medical bioengineers who work with technology and computers to help individuals with disabilities reach toward their maximum potential for an enjoyable and productive life. Helping the mentally disabled to learn, providing a voice for those who cannot speak, and transportation for the physically disabled are some of the activities of the rehabilitation bioengineer. Other bioengineers work in research laboratories located in medical schools, universities and government facilities. Here, they learn more about the workings of the living body. Their studies range from the microscopic biological building blocks

of life to whole body interactions. Some bioengineers study molecular interactions and cells as collections of molecules and other are studying organs composed of collections of cells. Still others make mathematical models of how parts of the body work together. Some bioengineers make man-made materials to repair and replace damaged organs. These materials may be used for contact lenses, dental implants, replacement hip joints, and replacements for limbs. Medical Bioengineers’ work spans all of engineering and medicine domains. The great potential, challenge, and promise in this endeavor offer not only significant technological outcomes but humanitarian benefits as well.
