Title: Impacts of millennials on change management

Theme: Great Resignation, Change management, Organizational Transformation, Organizational Behavior

Goal: Study of great resignation and millennials behaviour on change management.

Abstract: We are living a different moment for the study of change management. The arrival of new generations, formed basically by professionals who present non-linear thinking based on sustainable metrics and that expand the concept of profit, finds in organizations generations consolidated by structured thinking, based on procedures and focused on cultural maintenance based on the generation of profit, and in some cases, at any cost. Historically, the transitions of generations in organizations and macroeconomic changes have been used to explain the pillars of change management models. However, today, companies are living with a unique technological transformation of disruptive intensity. New technologies, especially those based on big data and metaverse force a rethinking of organizational models and anticipate characteristics that are derived from profound impacts on the organizational process. By systematically analyzing people, culture, and new hierarchy models, challenges are created for current aspects of change management indicating that ESG (environmental, social, and corporate governance) concepts are more comprehensive and essential for maintaining companies. New generations, technology and value creation with principles focused on social and environmental sustainability and governance consolidate short and medium term survival, but it is the organizations that best manage deep and constant changes that will ensure permanence in the business environment over time.

Title: Development of bioactive niobium phosphate glasses

Theme: Biomaterials and Bone remodelling

Goal: Propose mew biomaterial to remodelling bone after dental implant cirgury.

Abstract: Niobium phosphate glasses containing calcium and sodium were prepared by melting mixtures of (NH4)2HP04, sodium carbonate, calcium oxide, and different amounts of niobium oxide at 1400°C for 1 h. Glasses were cast in pre-heated cylindrical 304L stainless steel moulds to obtain samples for “in vivo” tests, and in bar shapes for mechanical tests. After casting, the samples were annealed in the range of 540 to 620°C, and characterized by X-ray diffraction, FTIR, Raman, and differential thermal analysis. Leaching tests were also performed in water to determine the glass chemical durability as a function of the niobium content. Test of toxicity were performed according to the ISO 10993-5 to check the toxicity of those glasses. Grafts were installed in rabbit’s tibia to determine the osseointegration. After 8 weeks of healing process, the animals were sacrificed, and the bone blocks containing the grafts were removed, fixed, dehydrated, embedded in an acrylic resin, and prepared for a histological analysis by light microscopy, polanzed light microscopy, and scanning electron microscopy. The morphometry was performed by measuring three different bone markers inoculated during the healing period. Diametral compression tests, three point bending tests, and measurement of hardness were performed to determine the influence of the amount of niobium oxide in the mechanical properties of glasses. Besides being a glass former, niobium helps to reduce the amount of water molecules in the glass structure. These glasses are non-toxic, and bioactive. No niobium was detected in the neo-formed bone. The tissues remodeling near the grafts is lower during the first weeks of healing compared to the following period of time and by increasing the amount of niobium oxide in the glass composition, no changes in the remodeling process were observed. Improvements in the mechanical properties of glasses were observed as a function of the niobium concentration. The elastic modulus, determined from the bending tests, is very close to the one of the cortical bone.
