- Organizational and methodological influence of risk management in projectsPublication . Gomes, Diogo Francisco; Dias, Ana Sofia Martins da Eira; Navas, Helena; Abreu, AntónioProject risk management is essential to manager`s decision making and business success, because it allows the manager to identify, analyse and decide on the most appropriate way to respond to different adversities that may arise during the development of new products, services, processes, projects, continuous improvement, etc. This requires a mind-set that risks have a major influence on the bottom line and use analytical methods or risk management software. It is essential to integrate the entire organizational structure into risk mitigation intervention. The purpose of this paper is to address some of the important topics to consider for well implemented and successful risk management. An approach is taken at both organizational and methodological levels.
- The applicability of welding technologies in the health sector: critical reviewPublication . Gomes, Diogo Francisco; Galvão, Ivan Rodolfo Pereira Garcia de; Loja, Maria Amélia RamosIn early years, biological bonding of tissues was mainly made through suturing. Conventional sutures, despite being reliable and relatively inexpensive, have a direct relation to post-operative problems. With the purpose of eliminating these concerns, significant research on new surgical sutureless approaches has been conducted. The present work, which consists of a critical review research, is aimed to study sutureless approaches based on welding technologies. An analysis of their technological evolution, their advantages and drawbacks, and the phenomena occurring during their operation was conducted. The integration of the welding technologies in the health sector, supported by innovative medical devices and new biomaterials, have led to the development of revolutionary photothermal and photochemical binding techniques. These techniques have presented improved results over the conventional mechanical techniques for tissue healing, with effect on a multitude of medical fields such as angiology, neurology, otolaryngology, ophthalmology, urology and dentistry. Medical parameters, such as post-operative pain, narcotics usage, tissue thermal response and operation time, have been significantly improved. Important work has been conducted to understand the biological tissue transformations and their relation to the temperatures reached during the processes. Actually, one of the most serious medical concerns associated with the implementation of welding techniques in health sector is the thermal damage. Many methods, such as temperature control feedback systems, saline solutions, mathematical models for prediction of temperature-tissue behaviours, biological solder solutions and dyes, have been developed to diminish or eliminate this concern. In this matter, the development of new image-processing techniques was also a major advance in the medical diagnosis and the anticipation of patient disease growth, with earlier surgical interventions and therapies. Furthermore, over the last 10 years, integration of robotics and nanotechnology enhanced biologic welding procedures with more efficient and safer intra-operative and post-operative procedures.
