A review of mental models research in child-computer interaction

AbstractResearch in cognitive science, science education, and developmental psychology has long investigating how children, based on their everyday experience, construct mental models of the world they live in. This paper provides a review of the research investigating the nature of mental models in the context of child-computer interaction, review elicitation techniques used within the field, and discusses its potential to further inform the design process. Exploring children's mental models of new technologies may bring about some further understanding in their cognitive and conceptual development, thus promting parents and teachers to guide them in exploring the new technological environment

Chronic wound management; surgical therapy and complementary nursing with Manuka honey

Objectives. This study aims to analyze the evolution of chronic wounds treated both surgically and by complementary nursing using Manuka honey. The parameters monitored were: presence/persistence of bacterial infection, the duration of healing, the recovery period and the patients\u27 quality of life. Materials and Methods. The study group and the control group each consisted of 10 patients, aged between 50-60 years, with chronic wounds of various etiologies but without other significant systemic pathologies. Data collection was carried out through anamnesis, physical examination and analysis of medical documents. Results. In the study group, the depth of the wound was reduced rapidly and significantly, with complete epithelialization after about four weeks. In the control group, the wound was completely healed by classical treatment, but in eleven weeks and in the form of an unaesthetic keloid scar. The recovery period of a chronic wound appears to be significantly influenced by the use of Manuka honey. Conclusions. Future studies on large groups of patients need to verify the potential therapeutic properties of this compound (anti-inflammatory, antibacterial, antifungal, antioxidant, autolytic debridement, etc.), as well as its adjunctive contribution to wound dressing (maintaining a moist environment and reducing trauma and unpleasant odors)
