Plataformas interativas de biofísica para os cursos da área da saúde / Interactive biophysics platforms for healthcare courses

Introdução: O ensino da disciplina de Biofísica para as ciências da saúde desde sempre exigiu grandes esforços por parte dos docentes. Com o avanço dos sistemas computacionais, os simuladores permitiram tornar algo que é abstrato (propriedades biofísicas) aos alunos em algo inteligível. No intuito de adequar-se a essas novas tecnologias, os docentese as grandes universidades adquiriram e iniciaram o uso dessas ferramentas para otimizar o ensino da disciplina. Pensando-se em uma alternativa disponível publicamente em língua portuguesa, o objetivo deste projeto de iniciação científica foi a criação de dois simuladores computacionais, o primeiro elaborado em planilhas do Excel e o segundo em plataformas com interface para uso em navegadores de internet com o intuito de calcular propriedades bioelétricas de membranas celulares e facilitar o ensino e o aprendizado desse tema para os alunos dos cursos da área da saúde. Material e Métodos: A elaboração do projeto compreendeu tarefas de levantamento bibliográfico, equacionamento de cálculos de biofísica e programação de sistemas em Visual Basic for Applications (VBA ®) e C# ® (ambas linguagens de programação proprietárias da Microsoft ™). Resultados e Discussão: O simulador de propriedades elétricas de membrana celular, nomeado de BioEletric9 já se encontra implementado e os testes realizados para averiguar sua funcionalidade e coerência dos cálculos foram satisfatórios, o que já permite utilizá-la em atividades didáticas. Conclusões: A planilha em Excel já é operacional e permite ao professor sua utilização didática como recurso informacional em sala de aula/laboratório de informática. O programa BioEletric9 encontra-se em seus últimos estágios de finalização e será submetido a umaotimização de layout depois de ter seus erros de execução corrigidos.Palavras chave: Mídias sociais, Biofísica, Ciências da saúde, Internet ABSTRACT Introduction: The teaching of biophysics for health sciences has always demanded great efforts on the part of the professors. Because of the computer systems advances, thesimulators can enable students to turn something abstract (biophysical properties) into something intelligible. In order to adapt to the new technology, professors and largeuniversities have acquired these tools and started using them to optimize the teaching of the subject. An undergraduate research project was created, as an alternative publicly available in Portuguese, where two computer simulators would be created, the first one elaborated inExcel spreadsheets and the second one in platforms with an interface for using it in internet browsers with the purpose of calculating bioelectric properties of cell membranesand facilitating the teaching and learning of this topic for students in health care courses. Materials and Methods: The elaboration of the project consisted of bibliographicsurvey, equation of biophysics calculations and systems programming in Visual Basic for Applications (VBA ®) and C # ® (both Microsoft ™ proprietary programming languages). Results and Discussion: The simulator of the electrical properties of cell membranes, named BioEletric9 has already been implemented and the tests carried out toascertain its functionality and the coherence of the calculations were satisfactory, which has already validated it to be used in teaching activities. Conclusions: The Excel spreadsheet is already operational and allows the teacher to use it as an information resource in the classroom or computer lab. The BioEletric9 program is in its final stages of adjustment and will be subjected to a layout optimization after having its execution errors corrected.Keywords: Social media, Biophysics, Health sciences, Internet

Model and method of contextual help to develop skills of power unit operator using training simulator

Development of operator skills at the facility may lead to significant risks of accidents, and emergency drills in case of accidents “on-site” is impossible. Therefore, the use of computer simulators for operator training is an established international practice. Skill honing means repetition of exercises and is prone to errors. To increase the efficiency of training, computer simulators provide the ability to stop simulation to refer to tutorials. However, tutorials do not provide an immediate solution of the problem, as for what the mistake is and how one should act in a particular situation. The aim of the study is to reduce the time for contextual information search by, first, developing a dynamic model of training scripts, and second, developing a method to interpret the above model and to find error description. Petri net (PN) is an adequate model of action scenarios for a user of a computer application. Petri net links actions and the conditions of their execution. However, in contrast to the actions of the application user, the ability of the operator to perform actions is determined not only by the state of the control interface, but also by the state of the object itself. Thus, it is necessary to improve previously proposed models and methods of their interpretation. A scenario model in the form of an open Petri net (OPN) is proposed. The model novelty is the dynamic marking of positions with the values of the variables of the control object and the presence of transitions that are triggered when discrete signals of the control system are received. The authors propose the method of interpreting OPN queries which returns reference information relevant to the context. A method of integrating contextual help into simulator which projects the state of the object and the operator's actions on the structure of the OPN is proposed. The results of the study have been implemented in 215 MW power unit simulator of Surgut State District Power Station №1, which is being developed by Tekon-Avtomatika LLC. The results can be used during development of computer simulators of similar objects. Linear computation efficiency of the access to context information is provided.

Cascade Temperature Control Data Analysis in Oil and Gas Industry

Currently, one of the most effective methods of personnel training for the oil and gas industry is training on computer simulators. Studies show that most often emergencies occur in small areas of large production facilities, which indicates the existence of a problem with the possibility of training and development of simulators for basic objects of complex production chains. Nowadays, there are a lot of technical and technological solutions in the field of simulators, however, the segment of simulators of basic units and equipment of oil and gas industry objects is practically absent. In order to develop computer simulators that fully correspond to real objects, it is necessary to build adequate mathematical models. Within the framework of this research, the development of mathematical and structural models of the basic object of the oil and gas industry has been performed.

Ergonomic Factors in Patenting Computer Systems for Personnel's Selection and Training

The authors identify ergonomic factors related to the composition, structure and typical functions in the process of taking into account the criteria for the protection of inventions when patenting technical solutions in the field of professional selection and training of operators and drivers of military and civil man-machine complexes. The article describes the ergonomic capabilities of selection methods and devices, technical results from the introduction of virtual, hardware-software and computer simulators for training welders, locomotive drivers, radar systems' operators, operator of remotely piloted aircraft, vehicles' mechanics-drivers. For the selection of patents in subclasses of inventions, criteria for expert evaluation of their ergonomics were first proposed based on such criteria as manageability, serviceability and usability.in total, three experts were involved, and the consistency of the solution (the concordance coefficient) during selection was w=0.67. In advanced research related to the construction of automated patent search systems, it is necessary to develop decisive rules for the selection of inventions. The authors of the article plan to develop criteria for the ergonomics of selected inventions for further analysis of promising systems for selecting and training specialists in such IPC categories as G09B9/00, G06F15/20 and A61B5/16.
