New Concept of Intelligent Wound Dressing
Substance losses, burns and injuries arising from various causes represent a constant problem encountered by homo sapiens throughout its existence. Rudimentary treatments, relatively effective and less effective, have left their mark on the way we perceive the presence and treatment of wounds caused by various factors. Searching through medical archives, we can trace the specific protocols for these medical conditions back to 2200 BC, when they were structured in three steps: 1) cleaning the skin lesion, 2) applying a dressing (from glue to various preparations) and 3 ) bandaging the skin lesion. Currently, the appearance of wounds on the skin is caused both by accidents in the performance of various activities and by certain diseases that manifest themselves through skin rashes or skin lesions. Their frequency is in the thousands, according to the latest statistics, affecting the majority of the population non-selectively. It is vital that skin lesions receive the necessary care and attention, commensurate with their severity. Being open wounds on the surface of the skin, it is essential that the treatment be meticulous and appropriate to their type, as skin lesions represent a threat to the patient's life. From infections to hydroelectrolytic imbalances specific to burns, the multitude of factors that influence healing highlight the need for a dressing that can be easily customized according to the specificity of the wound, the needs of the patient and that is affordable both from the point of view of production cost as well as its use, making death from skin lesions easily avoidable through an intelligent approach. One of the most complex biological processes and indispensable to humans is the healing of skin lesions. Healing involves a carefully regulated series of biochemical and cellular activities in tandem. Traditional therapies and substances of natural origin have been used to facilitate the regeneration process and accelerate the wound healing process, being applied with encouraging results. Despite the fact that these generally present a low cost, they can be more expensive than contemporary treatments and can be influenced by regional, seasonal factors, showing fluctuations from batch to batch, which could lead to unpredictable allergic reactions, side effects and inconsistent clinical findings. Currently, the standard of care for skin lesions is to clean the wound with antiseptic solutions to prevent infection, apply a dressing followed by bandaging to keep the dressing in place, and if necessary excision of the tissue that has become non-viable. In the case of diabetic ulcers, it is necessary to excise the tissue that has become non-viable and to maintain control over the level of glucose in the body.
On the Application of Inequalities Containing Sums of Minimum/Maximum of Numbers
Retail inventory management is a crucial part of many businesses due to the high profit associated with it as well as the uncertainty around it, especially for industries with short production cycles and a complex supply chain.Proper management ofretail inventories can lead to decreased inventory costs, prevent spoilage and obsoles- cence, and improve customer satisfaction, all of which lead to increased profits for the company.Inthispaper,wefirstproposeextendingawell-knowninequalityandtry to generalize it to other conditions and similar inequalities.The inequality involves multiple variables and how the maximum/minimum values of a subset of the numbers compare to the maximum/minimum values of the whole set of numbers.Our main contribution is applying such inequality in inventory management to help estimate the total cost of inventory management, which would allow us to determine the shutdown pointforaspecificcompanyusingthegeneralizationsoftheinequality.Lastly,weshow thatourestimatesarereasonableandproposesomefutureareaswheremoreworkcan be done.
