The article aims to identify the latest trends in research on renewable energy, sustainability and the environment. A total of 92,873 publications from 123 Scopus sources for 2020–2021 are compared using the scoping review method. The results show that the most cited works in this sample are those by authors from the Asian region. The research of these authors focuses on the security, efficiency and reliability of separate elements in energy systems. Besides, the paper considers the problems regarding COVID disease along with the renewable energy sources, perovskite and organic solar panels, nanostructured materials and high energy density. Finally, the paper analyses applications of computer science methods in research on renewable energy, sustainability and the environment. The findings evidently show that recent advancements in computer science methods were not extensively used in the discussed research domain and give a great room for novel strategies of prognosing, simulation and processes optimisation.

The paper describes the application of the traffic engineering framework together with application layer procedures as mechanisms for the reduction of network latency lags. These mechanisms allow using standard and inexpensive hardware and software technologies typically applied for office networking as a means of realising networked control systems (NCSs) with high dynamic control plants, where a high dynamic control plant is the one that requires the sampling period several times shorter than communication lags induced by a network. The general discussion is illustrated by experimental results obtained in a laboratory NCS with the magnetic levitation system (MLS), which is an example of a structurally unstable plant of high dynamics.

Confusion on a somatic basis is a dangerous problem mainly related with aging of the population. Data says that consciousness disorders concern 10-15% of patients in general wards, and up to 50% of patients admitted to geriatric wards. The persistence of the symptoms of confusion results in increase of agitation, disorganization, fear, which increases the risk of self-injuries of patients, it causes the need for parenteral feeding and hydratation, as well as maintaining water balance, and also disturbs cooperation, worsening the course and prognosis of the primary disease. It is believed that consciousness disorders are one of the most difficult diagnostic problems and the most difficult therapy problem among psychotic disorders. So far in Poland there have been no screening evaluation tools to assess the occurrence of confusion on the somatic basis. The purpose of this paper is to introduce the Polish translation of the widely used scale to assess consciousness disorders, intended also for middle personnel of health care – Confusion Assessment Method (CAM). Numerous studies over 16 years established the position of CAM as an exceptionally effective standardized diagnostic test, specifying the sensitivity of 94-100%, specificity from 90-95%, positive predictive value of 91-94%, negative predictive value of 90-100%. The questionnaire and instructions of its interpretation have been translated by doctors with active help from the original creators of CAM. Further studies are required in order to validate and determine the effectiveness of the newly formed diagnostic tool.
