Authors: Ivanova T. V. , Soshina K. V. 
Published: November 2024

The purpose of the study. A significant task today is to increase the socio-psychological well-being of students in a university setting. Due to the increased intensity of educational activity, its complexity, and multitasking, the mental stress of students is increasing. Significant stress factors are the new social situation of development; the situation of external assessment in the process of intellectual tests; individual and personal characteristics of participants in educational relations; students' concerns about the ability to cope with educational tasks.The purpose of our work is to explore the possibilities of using the potential of the Educational and Practical Conflict Resolution Center of Southwestern State University for the development of adaptive coping strategies of students.In our work, we investigated the preferred coping strategies of students, offered recommendations for creating psychological and pedagogical conditions for the development of students' coping strategies that contribute to successful adaptation to the conditions.Methods. Theoretical and methodological analysis of scientific sources on the research problem was used in the work; empirical research methods: testing using the following techniques: "Questionnaire of coping methods" by R. Lazarus and S. Folkman (Ways of Coping Questionnaire – WCQ), adapted by the Bekhterev National Research Institute; "Coping behavior in stressful Situations" by N. Endler, J. Parker.Results. In the process of empirical research, it was revealed that the most characteristic for students in a stressful situation is coping, focused on avoidance, which manifests itself in distraction. That is, a significant number of students prefer not to solve the problem, but to distract themselves from it by other activities.Among the methods of coping behavior, "escape-avoidance" is pronounced, which most researchers consider to be maladaptive. Coping strategies "distancing" and "positive reassessment" are significantly expressed, which are aimed not at solving the problem, but at reducing emotional involvement in it, preventing emotional reactions to frustration.Conclusion. Thus, there is an obvious need for students to develop problem-oriented coping strategies. In particular, the strategies of "self-control" and "solution planning", which will help students direct their efforts to a rational solution of the problem.
“É ROBIGUS QUE VEM, GIRA E BALANÇA”
Authors: Dos Reis Rabelo Milena 
Published: November 2024

O seguinte ensaio visual coloca em cena a prática contemporânea da Robigália – antigo festival agrícola romano, como é celebrada no santuário politeísta da Vila Pagã, localizado na zona rural de José de Freitas (PI). A festividade, incorporada ao calendário litúrgico do Paganismo Piaga, acontece no mês de abril e evidencia o aspecto agrário da estação chuvosa e de temperaturas altas no Piauí: o plantio cultivado é o meio sacralizado tanto pelas bênçãos do deus Robigus, que atua na proteção dos campos e lavouras, como pelo aspecto destrutivo da divindade – o qual pode colocar em risco toda a plantação pela ação de pragas, ferrugem e bolor. A oferta de guirlandas e alimentos feitos de milho, consumidos durante a celebração, constitui oferendas que ativam seu aspecto benéfico, e a queima do espantalho, ápice do ritual festivo, é a queima da face maléfica do deus honrado. Nesse sentido, as fotografias apresentadas aqui sugerem uma perspectiva imagética da mobilidade dessa divindade na prática local de uma religião integrada à rede transnacional do Paganismo Contemporâneo. Além disso, acompanham a produção de novos lugares sagrados para antigas religiões e seus diferentes efeitos de sentido, indicando modos de visualizar o protagonismo do lugar onde a religião é materializada, uma vez que “É Robigus que vem” de uma origem romana, mas que é (re)situado na prática do Piaganismo no Piauí.

Abstract: Omarigliptin (OMG) is an active substance for the treatment of type 2 diabetes and it is representing of the dipeptidyl peptidase IV inhibitors class, an important enzyme in the regulation of blood glucose. It was launched on the Japanese market in 2015 as a weekly dose innovation. The aim of this work is to report the results obtained of the OMG tablets solubilization in different media, to evaluate the dissolution profiles in the chosen media, propose the biopharmaceutical classification, in addition to validate the dissolution method. After solubility test, the dissolution assay was conducted and a rapid process of tablets disintegration and dissolution was observed in three media having different pH values, they were acid hydrochloric 0.01M at pH 3.1, sodium acetate buffer at pH 4.5 and potassium phosphate buffer at pH 6.8. The potassium phosphate buffer medium was chosen to proceed with the dissolution method validation. With the profiles obtained in the three tested media it was possible to conclude that the dissolution is very fast, with 100% of the active substance dissolved in less than 10 min for all tested media. In addition, with the evaluation of the dissolution profile obtained in this work and data available in the literature, it was possible to suggest that OMG belongs to class I of the biopharmaceutical classification system. The proposed method was validated and contained all the necessary parameters recommended by the official guides.

estereótipo e a representação do negro na literatura brasileira do século XIX
Authors: Ferreira Enio Rodrigues Pinheiro , Roque Marcia Cristina , Taufer Adauto Locatelli 
Published: November 2024

O império do discurso colonial na produção literária brasileira tem fundas raízes e se consolida através da representação de modelos interessados em manter a ordem de dominação racial e econômica. Tais modelos cristalizam personagens negros como devassos, infantis e, acima de tudo, vazios de agência histórica. Sendo assim, neste artigo, objetivamos recuperar alguns possíveis registros de agência dentro da literatura brasileira do século XIX, para isso, analisamos três obras de diferentes autores brancos contendo relações entre escravizados e não escravizados em contraste com duas obras de dois autores negros, nas mesmas condições. Nossa análise teve como base o conceito de discurso proposto por Michel Foucault, citado por Djamila Ribeiro em ‘Lugar de fala’, alinhado com a noção de fixidez e estereótipo, de Homi K. Bhabha, como signo da diferença racial na construção ideológica da alteridade. Com isso, percebemos como, através da deslegitimação de discursos desviantes da reprodução colonial, a representação da agência de personagens negros na literatura brasileira tem sido apagada de nossa história. Nesse sentido, esta pesquisa visa incorporar os estudos ao campo educacional através de novas perspectivas de análise literária, atuando na abertura de fissuras no nosso cânone e dando visibilidade a novos discursos.

Laser product safety — An international topic with regional similarities and differences
Authors: Henderson Winn , Frederiksen Annette 
Published: November 2024

Products emitting laser radiation can represent a potential hazard to the human eyes and skin. Therefore, manufacturers of laser products need to develop products with safety in mind to avoid potential injuries. The product development and evaluation from a laser safety aspect can be based on the international laser safety standard IEC 60825-1:2014. This product safety standard provides a classification scheme, related evaluation methods and limits, and requirements for the product's construction, labeling, and user manual. However, although this is an international standard, compliance with the standard does not automatically mean that manufacturers will meet all requirements of all countries and regions. Some countries base their national laser product safety requirements on earlier versions of IEC 60825-1, others have their own regulations, and some regions use deviating standards.
This paper presents an overview of regional and national similarities and differences in laser product safety and then focuses on a comparison between the international requirements defined by IEC 60825-1:2014 and the United States regulations based on the United States Code of Federal Regulations (CFR), Title 21, Chapter I, Subchapter J, Part 1040 (hereby simplified to be called ‘21CFR 1040’ for the remainder of this paper).
Impact of automotive LiDAR system architectures on laser safety calculations
Authors: Frederiksen Annette , Wang Yunfeng , Bi Wanjun , Meng Ying 
Published: November 2024

LiDAR, which is an acronym for light detection and ranging, is a sensing method that detects objects and maps their distances. This ability to accurately rebuild the 3D surroundings makes it essential for automotive vehicles in the path towards autonomous driving. There are many different system architectures, which can be used to build an automotive LiDAR system. As it is an emerging and very promising technology, a lot of companies try to find the best approach and there are ongoing discussions on the optimal wavelength and illumination principle.
In this paper we will discuss the impact of the system architecture on laser safety calculations. We focus on time-of-flight (ToF) systems, emitting pulsed laser radiation and detecting the reflected return signal. This is currently the most commonly used measurement principle, but there are a lot of system decisions to be made when building a ToF LiDAR system. First, the choice of the wavelength. Here we will discuss 905 nm and 1550 nm regarding their ocular tissue interaction resulting in different limits. Second, the illumination principle can be realized by different scanning methods. Examples are mechanical scanning, semi-solid state scanning, and no scanning, which is often named as solid state. Semi-solid state scanning can be realized by polygon mirrors, MEMS mirrors or Risley prisms. The scanning principle influences the interaction with the eye resulting in different laser safety considerations.
This paper discusses how the choice of the LiDAR architecture is related to laser safety and gives the biological reasoning behind it. Besides this some biased assertions are corrected.
High average power lasers in university settings
Authors: Moriena Gustavo , Sonoc Sandu 
Published: November 2024

High average power lasers, hundreds of watts to kilowatts, are common in industrial environments where the beams are used to cut, weld, or engrave high melting point materials such as metals. In the research environment high peak power lasers, from gigawatts to terawatts, are common for pulsed lasers (ns, ps and fs) used in ablation and ultrafast spectroscopy. However, due to the low pulse repetition frequencies, those lasers normally have intermediate average powers in the order of a few watts. In the last few years, groups at the University of Toronto have started requiring high-average power lasers for their projects. These lasers’ powers range from a few hundred watts to one kilowatt. Normally these types of lasers are completely enclosed and certified as “class I working environment” by the laser's manufacturer, but the particular needs of some projects they are used on require open beam lasers.
In this paper, we'll focus on two lasers, one used for welding in a machine shop environment and the other in a research group developing a novel metal 3D printer. We will discuss the challenges of controlling different types of hazards, such as high-power beams, respiratory hazards connected to metal powder, Oxygen displacement by inert gases, etc. Changes in the laser safety training designed for the operators (craftspeople), who don't have much experience working with lasers and have little knowledge about physics will be also presented.
Safely building a class 4 laser system: Building materials selection
Authors: Dabney Matthew 
Published: November 2024

To be a quality laser optics vendor, Edmund Optics (EO) needs to specify Laser-Induced Damage Threshold (LIDT) for the laser optics it sells. To date, EO relied on external testing houses for LIDT measurements. An in-house measurement was needed for faster turnaround time to improve the optical coatings processes.
Building a class IV laser system to perform these measurements required not only the technical knowledge and experience of laser systems and materials science but also proper laser safety. Being in a commercial manufacturing environment required the practical application of the ANSI z136.8(2014) laser safety standard and carefully designed laser safety engineering controls. The safety controls were designed to not only allow for class I operation by technicians for production purposes but also to allow controlled access to the class IV operation for system maintenance and research and development purposes by properly trained higher-level laser users.
To limit personnel access, the two operational modes of the system are selected by use of a key-controlled switch. This presentation walks through in detail the safety engineering controls built into this class IV, LIDT testbed including laser lab design, electrical safety, laser enclosures, interlock system, beam blocks, beam dumps, shutter systems, and development of a laser safety program. The materials used need to be suitable to handle the energy and power without failing in any of a number of possible ways. A frank description of how the materials were chosen and tested will also be presented.
Optical table dangers
Authors: Santucci James 
Published: November 2024

A Laser Safety Officer is required to verify that adequate control measures are in place for all Class 3B and Class 4 lasers. What does this mean? Most LSOs will concentrate on the controls that they are comfortable with i.e., Entryway Controls, Standard Operating Procedures, Signage, Labelling, and PPE. But what about the optical table and all the components that reside there. This is where your typical LSO will shy away because they just don’t feel comfortable, but this is where you should focus the most.
This talk will introduce the LSO to common optical table dangers and suggest practical solutions. Some of the items covered will be invisible beams, the “sacred horizontal plane”, vertical beams, rogue beams, leakage, back reflections, and non-beam hazards. Understanding these aspects will ensure that you do not fall into the trap of missing the precursors of most laser accidents, Hazards on the Optical Table.
Evaluation of prototype laser eye protection for dismounted close combat
Authors: Kinerk Wesley 
Published: November 2024

The United Kingdom’s Defence Science and Technology Laboratory (Dstl) conducted assessments of six modified off-the-shelf prototype laser eye protection (LEP) devices designed to protect dismounted soldiers against known laser threats. The prototypes were all dye-based and relatively low cost. The assessments included: 1) measurements of optical properties with comparisons to standards and requirements, 2) laboratory evaluations of the LEP’s effect on contrast sensitivity and colour vision, and 3) a field trial that examined the effect of four prototypes on militarily relevant target detection/recognition/identification tasks and the participant’s ability to navigate a small-scale navigation course under low ambient light (i.e. scotopic to low mesoptic) conditions.
The field trial included 12 military member participants with a variety of experience levels. It was conducted in a controlled environment that permitted the precise control of environmental lighting. In general, the prototypes exhibited good optical quality that met standards and protection requirements. All six prototypes showed decreased contrast sensitivity and colour discrimination relative to the clear ballistic eye protection condition that served as a baseline. For the navigation course, a within-subjects ANOVA showed significant main effects for ambient light level (F = 12.642, p = 0.006) and LEP type (F = 7.665, p = 0.001). There was also a statistically significant correlation between the integrated visual photopic transmission of the prototype and the overall acceptability rating reported by participants (r = 0.648, p &lt; 0.001 for the lowest, 30 mlux ambient light level). The results of this study will inform United Kingdom Ministry of Defence procurements of LEP that provide appropriate laser protection while also allowing wearers to function in low light environments.

En politisk vilja att förändra – men vad är problemet? En kritisk läsning av kommittédirektivet om att förbättra lärarutbildningen
Authors: Bylund Linus , Player-Koro Catarina 
Published: November 2024

Den här texten avser att problematisera den pågående reformeringen av lärarutbildningen i Sverige genom en kritisk läsning och analys av regeringens direktiv till utredaren, där avsikten att höja lärarutbildningens kvalitet och läraryrkets status formuleras. Utifrån Millers och Roses begrepp problematisering undersöks hur problem med den nuvarande lärarutbildningen konstrueras och vilka lösningar och förändringar som därefter framställs som naturliga och nödvändiga. Analysen visar att direktivet inte framställer nuvarande lärarutbildningar som bristfälliga. I stället kopplas problem med kvalitet i lärarutbildningarna samman med brister hos studenterna, bristfälligt samarbete mellan lärosätena samt samhällsförändringar i stort. I diskussionen belyses hur den politiska strävan att förändra lärarutbildningens vetenskapliga grund kan ses som ett steg mot avprofessionalisering av läraryrket. Vidare lyfts risken att höjda antagningskrav och införandet av lämplighetsprov kan leda till att vissa studentgrupper exkluderas, samt vilka konsekvenser en sådan förändring kan medföra.
ENGLISH ABSTRACT
A Political Will to Change – But What Is the Problem? A Critical Reading of the Committee Directive on Improving Teacher Education
This text aims to problematize the ongoing reform of teacher education in Sweden through a critical reading of the government’s directive to the investigator, where the intention to improve the quality of teacher education and the status of the teaching profession is formulated. Using Miller and Rose’s concept of problematization, the analysis explores how problems with the current teacher education are constructed and what solutions and changes are subsequently presented as natural and necessary. The study shows that the directive doesn’t depict the current teacher education as deficient but links quality problems to student shortcomings, poor institutional collaboration, and societal changes. The discussion suggests that changing the scientific foundation of teacher education may lead to deprofessionalization. Furthermore, the risk is raised that increased admission requirements and the introduction of aptitude tests could lead to the exclusion of certain student groups, and the potential consequences of such a change are discussed.
