Work environment risk indicators for pharmacists in the preparation of extemporaneous medicines

The pharmaceutical sector is one of the leading sectors of the Latvian economy, but the extemporary prepared medicines still occupy a small market share. The study involved 44 pharmacists and pharmacist assistants preparing extemporal medicines, while the control group included pharmacists and pharmacist assistants who only attend customers in pharmacies. The aim of this study was to identify work environment risk indicators for pharmacists preparing extemporal medicines in open-type pharmacies. In the research, we used methods of observation and survey to identify the views of pharmacists and pharmacist assistants preparing medicines in open-type pharmacies. The study concluded that pharmacists and pharmacist assistants who prepare medicinal products in open type pharmacies are exposed to a wide range of work environment risks, especially to the chemical risks. During our investigation, we identified the main work environment risk indicators: occupational accidents, workload, lack of information, exposure to chemicals, length of service, work environment quality, and use of personal protective equipment.

Dance and Science: an analysis of the creative process behind "Transitions", a show by Contemporary Dance Company of UFRJ

This study proposes an esthetic reflection on the influence of the biological sciences on dance as a variety of contemporary art. The relationship between science and art in this study is grounded on François Dagognet’s hyperphenomenology, particularly his representation of the major role played by the image-symbol as essential base of present-day scientific activity [1]. Contemporary dance creators and companies such as Wayne Mac Gregor, Phylobolus Dance Company and Liz Lerman Dance Exchange are analyzed, in order to highlight how some biosciences themes are explored as creative potentials in their dance performances [2,3,4]. We aim at relating biological shapes and patterns existing in the cellular and molecular universe with the fundamentals of dance described by Helenita Sá Earp. Earp’s conception posits dance as wide-scoped knowledge, including a “science of dance” where intuition works as basic foundation and its epistemology is made of an open type of knowledge named “dance parameters”, namely motion, space, shape, dynamics and time. These parameters allow establishing access points for multiple connections within the realm of dance. This approach tends to generate a kind of access to body actions stimulating interdisciplinarity between several areas of knowledge [4]. As study-case, we focus methodologically on the processes of esthetic creation involved in the production of a multimedia show entitled “Transitions” by appealing to biochemical notions, especially some features of cytology and cellular morphology, cell proliferation and processes of cellular transportation [5].

Graphical Interface for the Recommendation System

Today, mathematics plays a huge part of our everyday life. But due to the poor school education and lack of open access resources, many students find it difficult to be fully prepared for the independent external evaluation in mathematics, especially geometry. Although much has already been done to conduct higher knowledge results, lots of students still have gaps in understanding simple problem solving. Clearly, geometry requires a more fundamental and visual implementation to the studying process than algebra in order to increase the overall knowledge level of Ukrainian applicants for higher education. Students often do not have access to innovative studying instruments in their schools necessary for successful completion of geometry classes, which is why they receive weak results in tests.In the research, we are concentrating on the planimetry problems, because they can be easily produced in a written form. After analyzing all types of describing a problem, the best option for the system is the open-type problems with the short answer.The article concentrates on creating a graphical interface module, implementing it to the existing language processing module, and introducing a recommendation system that demonstrates a new fundamental instrument that can change the learning technique and give a comprehensive way of explaining geometry problems.The created system receives an open-type planimetry problem in Ukrainian language, processes it using the NLP module, and transfers the data directly to the interface module, which creates an image of the problem. Then the student can try to draw all the required figures, while the system continuously checks the progress. Recommendations (hints) can be applied during the process by the system.Interface and the NLP modules were created separately, independently, and using different programming languages. For that purpose, we use an intermediate stage – JSON file, which is used to transfer the processed information.

Calculation of the Eddy Current Losses in a Laminated Open-Type Transformer Core Based on the A→,T→−A→ Formulation

Losses due to eddy currents in an open-type transformer core are significantly reduced by the lamination of the transformer core. In order to further reduce the eddy current losses, the open-type core often has a multi-part structure, i.e., it is composed of several more slender cores. The complete homogenization of such a core is not possible when an A→,V−A→ formulation is used, where A and V represent the magnetic vector potential and electric scalar potential, respectively. On the other hand, an A→,T→−A→ formulation, where T represents the electric vector potential, enables the complete homogenization of the general open-type core, but the simulation converges poorly due to the large number of degrees of freedom. By eliminating the redundant degrees of freedom, the convergence rate is significantly improved, and is at least twice as good as the convergence rate of the simulation based on the A→,V−A→ formulation. In this paper, a method for the calculation of the eddy current losses in an open-type core based on the A→,T→−A→ formulation with the elimination of redundant degrees of freedom is presented. The method is validated by comparison with a brute force simulation based on the A→,V−A→ formulation, and the efficiency of the method is determined by comparison with the standard homogenization method based on the A→,V−A→ formulation.

Application of uv radiators for disinfection of air and surfaces in premises

Objective: We compared the antimicrobial efficacy of different types of UV radiators. Materials and methods: In the work, we used the ultraviolet radiators of various types and manufacturers recommended for disinfection of air and surfaces of the premises. The effectiveness of surface disinfection from the test microorganisms Staphylococcus aureus and Pseudomonas aeruginosa was established by the Regulations “Methods for testing disinfectants to assess their safety and effectiveness". We determined a total number of aerobic microorganisms and molds according to the State Pharmacopoeia of Ukraine 2.0, p. 2.6.12. Results: The efficacy of the use of ultraviolet radiation for disinfection of the surfaces with the most resistant representatives of gram-negative and gram-positive microorganisms using a portable "Individual ultraviolet irradiator ALED UVC-1W" for 1 min. was established. The disinfection effect was 4.02 lg for S. aureus and 4.08 lg for P. aeruginosa. The effective action of the bactericidal ultraviolet radiation with the use of open-type radiators (with louvers) "UV-BLAZE" was demonstrated. A decrease of the total number of microorganisms, including molds in the air, by a factor of 36 (room № 1) and 136 (room № 2) was noted. Disinfection of the surfaces in the premises for the similar indicators was 98.6% and 99.5%, respectively. A decrease in the level of microbiological air pollution in the premises, when using LED radiation with the open-type ALED T5NXXX UVC-5W-01 luminaires for a long period of time (8 hours), was noted. The disinfection efficacy was 77% for bacteria and 83.3% for fungi.

Open Perilunate Fracture Dislocation with Lunate Extrusion: A Case Report and Literature Review

Perilunate injuries with lunate extrusion are extremely rare, representing an extreme subgroup of the Mayfield type 4 spectrum, with prognosis and management remaining controversial. We present a 45-year-old man with an open type 4 perilunate fracture dislocation, with lunate extrusion through the volar skin. Despite emergent treatment with open reduction and internal fixation, lunate and scaphoid proximal pole avascular necrosis developed. However, the overall functional outcome was satisfactory for daily activities at 30 months follow-up, with substantial improvement in the range of motion after hardware removal. To our knowledge, this is the third reported case of an open perilunate injury with lunate extrusion in the literature.
