Preliminaries and Basic Knowledge on Time Scales

Past: In 1960 Thornley published the first description of SEM studies carried out at low beam voltage (LVSEM, 1-5 kV). The aim was to reduce charging on insulators but increased contrast and difficulties with low beam current and frozen biological specimens were also noted. These disadvantages prevented widespread use of LVSEM except by a few enthusiasts such as Boyde. An exception was its use in connection with studies in which biological specimens were dissected in the SEM as this process destroyed the conducting films and produced charging unless LVSEM was used.In the 1980’s field emission (FE) SEM’s came into more common use. The high brightness and smaller energy spread characteristic of the FE-SEM’s greatly reduced the practical resolution penalty associated with LVSEM and the number of investigators taking advantage of the technique rapidly expanded; led by those studying semiconductors. In semiconductor research, the SEM is used to measure the line-width of the deposited metal conductors and of the features of the photo-resist used to form them. In addition, the SEM is used to measure the surface potentials of operating circuits with sub-micrometer resolution and on pico-second time scales. Because high beam voltages destroy semiconductors by injecting fixed charges into silicon oxide insulators, these studies must be performed using LVSEM where the beam does not penetrate so far.

In the submitted study the problem of the formation of financial literacy of students at informatics lessons and relevant training of future informatics teachers is considered. Financial literacy is understood as a set of basic knowledge in the field of finance, banking, insurance, as well as budgeting for personal finances that allow a person to choose the right financial product or service, soberly assess and take risks that may arise during the use of these products, correctly accumulate savings and identify doubtful (fraudulent) investment schemes. The authors conclude that successful development of meaningful lines of the course of financial literacy requires integration of a few school subjects, such as mathematics, history, informatics, social science and literature. The role of modern informatics teacher in the formation of financial literacy of students is great. Therefore, in the training of a future informatics teacher, it should be paid the attention to issues related to the study of elements of financial literacy in informatics lessons. In order to solve the problem, the authors propose to use the special course “Basics of work in 1С:Enterprise”, which is implemented at Penza State University. The article contains a program of the course and the methodological recommendations for its implementation.

Acidentes e fatalidades podem acontecer desde simples contusões até as mais urgentes hemorragias e parada cardiorrespiratória. Os primeiros socorros realizados de forma adequada podem minimizar os agravos e até mesmo salvar vidas. No âmbito escolar, situações de emergência fazem parte do cotidiano e é essencial que Professores de Educação Física tenham um conhecimento básico para atender as necessidades escolares. O presente estudo teve como objetivo verificar o conhecimento dos Professores de Educação Física (EF) da rede pública de Ensino da Cidade de Santa Cecilia-SC com relação aos Primeiros Socorros (PS). Caracterizou-se em natureza descritiva, transversal, com análise quanti-qualitativa dos dados. Participaram do estudo 11 Professores de EF. Para a coleta de dados, foi desenvolvido um questionário abordando aspectos conceituais, procedimentos e atitudes referentes ao cotidiano profissional. Do total, apenas um professor não teve a disciplina de PS na graduação. Os professores na sua minoria se sentem aptos a prestar os PS e inclusive assumir as situações, demonstrando conhecimento satisfatório na teoria, mas na prática sentem-se inseguros para agir diante de situações mais graves. Destaca-se que mais de 80% sabem como agir em atendimentos menos agravantes. Já nas situações de parada cardiorrespiratória (RCP) e hemorragias, os mesmos relataram que necessitam de um treinamento mais atualizado. Em crianças principalmente eles não sentem muito seguros em prover o auxílio. Foi possível concluir que os professores de EF apresentaram um nível de conhecimento satisfatório na teoria, mas sugerem atualizações periódicas em forma de cursos.Palavras-chave: Primeiros Socorros.

First aid performed properly can minimize the aggravations and even save lives. In the school context, emergency situations are part of the daily life and it is essential that Physical Education Teachers have a basic knowledge to carry out the school needs. This study verified the Physical Education (PE) Teachers knowledge from Santa Cecilia-SC public teaching related to first aid. It featured in descriptive nature, transversal, with quantitative and qualitative analysis of the data. Eleven PE teachers participated of the study. For the data collection, it was developed a questionnaire addressing conceptual aspects, procedures and attitudes concerning professional daily life. From the total, only one teacher did not have the first aid subject at the college. Teachers in their minority feel able to provide the first aid and even take on the situations, showing satisfactory theory knowledge, however in real life they feel insecure to act on before serious situations. It points out that more than 80% know how to act before less aggravating calls. Nonetheless, during cardiopulmonary arrest (CPR) and hemorrhages, they reported the need of an updated training. Mainly in children, they do not feel safe to provide the aid. It was possible to conclude that Physical Education Teachers showed a satisfactory level of knowledge in theory, however it suggest courses periodic updates.Keywords: First Aid. Faculty.
