Silicon catalysts have very low catalytic activity in polyester (PET). However, titanium catalysts have high catalytic activity in polyester. The simultaneous use of titanium and silicon catalysts is effective in reducing the activity of a single titanium catalytic base agent. In addition, the glycol salts of titanium and silicon (Ti-EG and Si-EG) prepared in the present invention for use in the polyester catalytic process can avoid the introduction of other groups of impurities during the polyester catalytic process, which would lead to premature capping of the polyester in the process of polycondensation and chain building and make it difficult to increase the molecular weight, and thus affect the quality of the polyester. It has been verified that the ratio of Ti:Si is 1:1 (mol), and total amount added to the catalyst is 0.15% of the raw material amount, and the polycondensation temperature was 260-280 °C for 60 min. Compared with the single Ti-EG catalyst, the b* value of the synthesized PET was significantly reduced, and the molecular weight and other indexes did not change too much. In addition, at the end of catalysis, the catalyst was uniformly dispersed in the reaction system, which could be used as a matting agent for PET.

The present study investigates, in light of a debate carried out by post-Kantian authors, Sigmund Freud's conception of activity. In order to do so, we engage in a dialogue between the psychoanalyst and two authors, Fichte and Marx, and delimit, albeit not exhaustively, Freud's place in the construction of a crucial concept for the History of Philosophy during this period.

ABSTRACT The objective of this study was to analyze data on physical activity and rumination time monitored via collars at the farm coupled with milk yield recorded by the rotary milking system to predict cows based on several disorders using the binary Logistic regression conducted with R software. Data for metritis (n=60), mastitis (n=98), lameness (n=35), and digestive disorders (n=52) were collected from 1,618 healthy cows used to construct the prediction model. To verify the feasibility and adaptability of the proposed method, we analyzed data of cows in the same herd (herd 1) not used to construct the model, and cows in another herd (herd 2) with data recorded by the same type of automated system, and led to detection of 75.0%, 64.2%, 74.2%, and 76.9% animals in herd 1 correctly predicted to suffer from metritis, mastitis, lameness, and digestive disorders, respectively. For cows in herd 2, 66.6%, 58.8%, 80.7%, and 71.4% were correctly predicted for metritis, mastitis, lameness, and digestive disorders, respectively. Compared with traditional clinical diagnoses by farm personnel, the algorithm developed allowed for earlier prediction of cows with a disorder.

Addressed to Philosophy teachers, this text sums up the contributions offered by a university training aimed at filling the blanks on what is known about work. By revisiting concepts such as subject, values, health and norms... it is defended that all work, and even all human endeavor, is always, to different extents, one's use of self and use of self by others. This may provide a generic work definition. However, it is noticed that knowledge "by others" rules the work activities in detriment to the knowledge at the core of "one's use of self". This would introduce an historical version of work, presenting it as a constraint, as it is characterized in social categories where inequalities stand out. The origin of this historical perspective is then questioned, suggesting that such drift from work is undoubtedly central to the anemia of current democracy. [ABSTRACT FROM AUTHOR]

Mashua (Tropaeolum tuberosum) is an Andean tuber rich in phenolic compounds and glucosinolates, known for its consumption that allows the prevention and/or reduction of getting diseases. The present research evaluated the effect of different types of post-harvest management (sunny, bleached, and freeze-dried) on glucosinolate content and its relationship with myrosinase activity. It is also important to note that when plant cells are damaged and glucosinolates meet the plant's myrosinase, which hydrolyzes them and degrades them to other compounds. In the present research, the types of glucosinolates, the content of glucosinolates and the activity of myrosinase of the purple variety of fresh raw mashua and in mashua treated by several types of processing were evaluated, including the previous treatment (sunny and unscrewed), the boiling treatment and the microwave treatment, with whitening times of 3, 4, 5 and 6 minutes, being the condition of the tuber at the time of bleaching in whole form and by cutting, to then be subsequently subjected to lyophilization treatments. Five glucosinolatos (GSL) were identified: 5-methylsulfinilpentile, 4-hydroxybenzyl, 4-hydroxy-3-indolylmethyl, benzyl and 4-methoxybenzyl, of which 4-methoxybenzyl glucosinolate is the most abundant, symbolizing 98% and 95% of the total GSL in the purple ecotype. According to the total concentration of glucosinolates found in the studied variety (purple), it must be 74.22 and 110.60 micromoles per gram of dry base (μmol/g dry weight), so mashua can be considered, the edible plant with the highest existing GSL content.

The objective of this article is to question the ergonomics on the basis of Roberto Novaes’ documentary-intervention, "Mulheres das águas" (women of the waters), which describes and comments on the activities of the fisherwomen in the mangroves of the North-East of Brazil. Their way of life, their work and the survival of their families are threatened by pollution from large industries and by tourism which damages the ecosystem. The documentary highlights the commitment and resistance of these women in their quest to preserve fishing grounds, maintain and expand their social rights, and improve their working and health conditions. We explore questions raised by the documentary that challenge contemporary ergonomics and appeal to: the category of analysis of intersectionality, the notion of extended harmfulness, the tradition of Freire’s education, and the approach of the territory as being acted in work activity.

In Western societies, welfare intervention in homelessness assumes that each individual is homeless due to an intimate flaw that must be corrected through a process of re-subjectivation that empowers by making them autonomous, thus making them capable of leaving the street and guaranteeing their survival through the performance of a paid activity. One of the most relevant intervention practices is the injunction to activity, a process by which homeless individuals are encouraged, either gently or coercively, to perform various activities under the guidance of others. The objective of performing these activities is to make homeless individuals produce themselves as subjects who are committed to changing who they are. Fieldwork was carried out to understand this process of re-subjectivation through the exogenously-directed activity, which consisted in direct observation of the practices of welfare intervention professionals, and of interactions among homeless individuals. The fieldwork showed that the goal of producing autonomous subjects cannot be reached through such tutelary activity. Due to the structural obstacles to leave the street and to the situation of heteronomy in which these autonomy-fostering practices unfold, such activities block both the autonomy of homeless individuals and the intimate transformation that they aim to promote.

Celebrating the 100-anniversary of the birth of Paulo Freire (1921-1997) and his fifty years of political-educational work (1947-1997), we present this paper aiming at contributing to consolidate the appropriation of Freire's theory and epistemology by those who are interested in understanding-transforming the real work situations, emphasizing the Activity's point of view. We bring to this dialogue (central concept for us) the concepts of Ergology, Activity Ergonomics, Work Psychodynamic, Activity Clinic and Italian Model of Worker's Struggle for Health (MOI, in Portuguese), which share a common horizon of analyses and paths. Dialogy, awareness and lovingness are hereby explored as strong ideas to understand-transform both work and life. [ABSTRACT FROM AUTHOR]

This article intends to study four principles of the movement of matter (living force, dead force, inner force of the molecule, vital force) that appear in Diderot's Le Rêve de d'Alembert (1769), Principes philosophiques sur la matière et le mouvement (1770) and Éléments de physiologie ((1782). With such a study, we would like to show the possibility of what we call inert sensation and active sensation, based on a fifth principle: the neural force. Our hypothesis is that the reasoning, which underlies Diderot's theory of the universal sensibility of matter, leads to the ideas of inert and active sensation. [ABSTRACT FROM AUTHOR]

In this article we discuss the discursive functioning involved in the edition of Precedent 610-STF. Although it has no binding effect, this Precedent has governed decisions in different Brazilian courts since then. Continuing a discussion on the inadequacy of its normative content, proposed by Moreira et al. (2019), in this article, we ask ourselves about the conditions of enunciability that guaranteed its emergence and its consolidation. To this end, we proceed to the analysis of the enunciative scene involved in / by the texts that underlie the five HCs that substantiate the edition of the epigraphed Precedent, based on a discursive-ergological approach. Questioning the statements in the context of work of criminal justice, we find an enunciative scene in which the values of two legal assets are confronted: life and heritage. The discursive functioning that establishes this confrontation points to a structuring feature of the legal system that, aligned with capitalist rationalities, associates the right to life with the right to property.

ABSTRACT With the increasing scale of farms and the correspondingly higher number of laying hens, it is increasingly difficult for farmers to monitor their animals in a traditional way. Early warning of abnormal animal activities is helpful for farmers’ fast response to the negative impact on animal health, animal welfare and daily management. This study introduces an automatic and non-invasive method for detecting abnormal poultry activities using a 3D depth camera. A typical region including eighteen Hy-line brown laying hens was continuously monitored by a top-view Kinect during 49 continuous days. A mean prediction model (MPM), based on the frame difference algorithm, was built to monitor animal activities and occupation zones. As a result, this method reported abnormal activities with an average accuracy of 84.2% and a rate of misclassifying abnormal events of 15.8% (PFPR). Additionally, it was found that the flock showed a diurnal change pattern in the activity and occupation quantified index. They also presented a similar changing pattern each week.

Phosphogypsum is a residue that has been used by the cement industry as a substitute for the natural gypsum, used as a clinker additive during the production of Portland cement. There is a potential increase in this residue use since the large amount of phosphogypsum is generated as outcome of the phosphate fertilizer industries. However, phosphogypsum can be considered a source of radioactive contamination since it has 226Ra in its composition. Depending on the concentration of 226Ra, from the radiological protection point of view, this may cause a problem because this radionuclide and its direct decay product 222Rn along with other decay products, represent the largest fraction of radiation internal dose received by people. In order to evaluate the level of radiological risk that may be associated with the use of phosphogypsum, it is necessary to identify the concentration of 226Ra in building material. The aim of this research is to analyze the samples of phosphogypsum in relation to the concentrations of 226Ra, determined indirectly through 222Rn activity measurements. This measurement process has the advantage of being fast, convenient and relatively inexpensive when compared to traditional 226Ra concentration in samples measurement methods. Proposed physical-mathematical model was used to establish radium concentration from radon exhalation rate from cement mortar samples. The 222Rn activity measurements were performed with a portable detector with cubic phosphate samples with 50 mm edges each placed in a closed atmosphere of the sampling chamber until secular equilibrium is achieved. Obtained concentrations of radium activity in studied samples of phosphogypsum and cement mortars were found below the limits recommended by CNEN and international regulation.

This paper discusses the pandemic of COVID-19 as an integral phenomenon, which is formed not only by the virus in itself but by the whole range of relationships and activities emerging from this phenomenon. The object of analysis is Science Education, especially how it has been developing throughout the pandemic situation. In this sense, we point out the need to understand the current pandemic, taking into account not only the virus's microfauna but the pandemic as a social issue. In this scenario, in educational terms, emerged what was called "remote emergency activity" emerged and even with the use of technology it is necessary to highlight that no technology, however best and most developed, will supply the work of a teacher, or better, contact and human sense cannot be replaced. Concerning educational activities in science, they must go beyond a mere "transmission of content", that is, an Education in Science for the development of concrete possibilities of human emancipation, through the Discussions About Science. Finally, we consider that we will not rebuilding human culture from the beginning in a post-pandemic world, but continue to develop movements of resistance and struggles engaged in transformation based on Science Education attentive social justice.

Starting from a research in psychodynamics of work, the paper aims to explain the consequences of the new forms of work organization on the activity of deliberation and cooperation of workers, on the one hand, and on their possibilities of development and action, on the other hand. It is particularly concerned with showing how the denial of reality and living labor, supported by managerial transformations in the organization of work, disqualifies the language of activity emanated from workers and bars access to effective work, thus "preventing” deliberation on living labor. Finally, it questions the necessary conditions for a reinstatement of deliberation, so that it takes precedence over a thought invaded by the social imaginary and that can open the way to the challenge of symbolic domination and to the resistance to governance by numbers.

This paper aims to compile and test activities in the areas of mathematics, demanding the active participation of students, through experiments and trials, joining dialog to theory as a methodological option that is, aiming to insert mathematics through active experiments to reproduce, in the classroom, students' daily activities. In this sense, a reflexion about the needs to turn mathematics more attractive was made, where the classroom is not an isolated space, but providing a discussion space to unite theories and practices with the aim of training active students in their teaching and learning process. This activity model was developed in a school in Rosario do Sul -RS, with a 9th grade middle school, with 12 students and realized through four distinct moments: introduction to initial concepts, laboratorial trials, real world trials using an app, and, finally, performing calculations and discussing their results. At the end of this paper it was possible to realize that the students made significant gains in their learnings confirming that it is possible to perform mathematics through practical activities and with ludic experiences on final years of middle school.

Social and organisational changes are causing deep transformations, which can generate quite concerning psychosocial dynamics in the work places. The “psychosocial risks” result from a set of conditions and factors inherent to the organisation of the work and it is important to identify them. This study's main purpose was to verify whether the Advanced Technicians on Occupational Health (ATOH) who perform their activity in Portugal are exposed, or not, to psychosocial risk factors and whether, consequently, their health condition is deteriorating. The findings show they are exposed to psychosocial risk factors related to the work conditions and characteristics. Their health is perceived as good and not entirely work-related, though some of their health problems are made worse by the work. The less the ATOH are affected by the psychosocial risk factors, the better do they perceive their health.

Organizations tend to create and hold routines that make their work predictable. Changes in organizations often introduce unexpected effects, increasing uncertainty and operational casuistry, affecting people and their activity. The literature on organizational change favors the analysis of factors underlying the change processes, including the role of purposive activity of members of the organization (agency), however, shortly addresses the effects these changes generate about the specific activity of organizational change. Relevant topics are discussed regarding change processes, and effects they entail on people and their performed activities.

This article focuses on the use of personal protective equipment (PPE) with regard to biological risk. It is based on an action research approach conducted in a confined biological analysis laboratory, of “class 3” safety level. The first results, coming from the analysis of risk perception and the operators' activity, show that their actual use of PPE depends on both the safety prescription and their own perception of risk in the work activity. At the same time, depending on the constraints caused by the PPE in situation, operators adjust the way they wear or use them, whilst implementing additional strategies to reach both efficiency and safety in the work activity. Thus, work safety in this context requires considering the PPE in a broader framework: the relation between operators, their risk perception and real work activity.

Purpose: This article is the result of an ethnographic study carried out in a settlement in the interior of Paraná, Brazil, which, from the perspective of the Social Learning Theory, aimed to understand how the learning of the productive baking activity of settled women occurs, serving as a path to a diversity of studies that seek to understand why certain practices emerge, institutionalize or are altered over time through an approach that sees them as a collective endeavor. Originality/value: In revealing the sense of the activity and participation of these women in the baking activity and their relation with learning in the enterprise, this study was justified for its contribution to the understanding of this learning, answering questions that can serve as reference to understand the reality of productive groups of this new economy. Design/methodology/approach: The proposals of Engeström (2009) and Nicolini (2009) formed a methodological package whose results showed the sense of activity as the search for an identity, the will to belong, factors generators of internal and external contradictions that extend the horizon of possibilities of the enterprise, leading to an expansionary cycle that causes the development of learning. Findings: The results revealed that in the system of activity, learning and participation are intrinsically related, associating the development of the group with participatory learning and the negotiation of meanings in the community in which it is inserted, linking past and future, individual and collective, new and existing knowledge, in a transformative movement of identities of the subjects and generator of a socially constructed knowledge. Objetivo: Este artigo é resultado de um estudo etnográfico realizado em um assentamento no interior do Paraná que, sob a perspectiva da Teoria Social da Aprendizagem, pretendeu compreender como ocorre a aprendizagem da atividade produtiva de panificação de mulheres assentadas, servindo como um caminho para uma diversidade de estudos que buscam entender por que certas práticas emergem, institucionalizam ou são alteradas ao longo do tempo por meio de uma abordagem que as vê como um empreendimento coletivo. Originalidade/valor: Ao revelar o sentido da atividade e participação dessas mulheres na atividade de panificação e sua relação com a aprendizagem no empreendimento, este estudo foi justificado por sua contribuição para a compreensão desse aprendizado, respondendo a questões que possam servir de referência para entender a realidade dos grupos produtivos dessa nova economia. Design/metodologia/abordagem: As propostas de Engeström (2009) e Nicolini (2009) formaram um pacote metodológico cujos resultados mostraram o sentido da atividade como a busca de uma identidade e a vontade de pertencer, fatores geradores de contradições internas e externas que ampliam o horizonte de possibilidades do empreendimento, levando a um ciclo expansivo que provoca o desenvolvimento da aprendizagem. Resultados: Os resultados revelaram que, no sistema de atividade, a aprendizagem e a participação estão intrinsecamente relacionadas, associando o desenvolvimento do grupo com a aprendizagem participativa e a negociação de significados na comunidade em que está inserido, ligando passado e futuro, individual e coletivo, conhecimento novo e existente, num movimento transformador de identidades dos sujeitos e gerador de um conhecimento socialmente construído.

What is the relevance of thinking about work as a producer of values today? This article discusses current implications between work and the production of value through a review of theory and concepts (concepts, constructs, notional networks) in the field of humanities. Several seminal authors have been chosen according to four disciplinary fields (Sociology, Economics, Law, Politics) to reflect on the relationship between work and value in current times. In this review, we have noted that the concept of work is questioned due to the volatility of the problem related to the formation of economic value in the contemporary world, where forms of work organisation and ways of producing goods have been restructured. How do we address the issue of values and their production and circulation in the current work reorganisations? Would the old question of work as the foundation of value that merged Smith's political economy with that of Marx still be relevant? Would the old issue of tensions in the labour law between a commercial right and a social right still make sense? We conclude that it is necessary to rethink the ways in which to approach the work experience so as to give visibility to the ongoing conflicts of value in work situations as a way, par excellence, of validating the relevance of work as a producer of values.

On the threshold of the 21st century, the issue of Quality of Work Life (QWL) is becoming more and more important on the agendas of leaders and managers from the corporate world. This interest arises in the midst of a scenario that combines, concomitantly, the restructuring of productivity, the worsening of negative indicators for health and safety at work and also the risks associated with reaching corporate goals and objectives. It is in this context that organizations are increasingly investing in QWL. The aim of this text is to provide a 360 degree analysis of the hegemonic QWL practices found in Brazilian organizations, with the intention of providing evidence of their “welfaristic” nature, and, moreover, of their limitations for a genuine improvement in health and safety indicators. Overcoming a “welfaristic” bias requires returning workers and their activities to the role of protagonists for the effective promotion of Quality of Work Life.

This paper is the result of a master’s research developed at Federal University of Minas Gerais (UFMG) in the Graduate Program of Psychology. Its general objective is to understand what psychiatrists do in the Psychosocial Care Center (CAPS) when they work between the prescribed and the real. In specific terms, analyze how they make use of themselves and how they mobilize the six Competency Ingredients of the activity (IGR’s) in the real work. Through the theoretical and methodological principles of the Psychosociology of Work, dialoguing with the Ergology approach, we conducted a qualitative research in four Psychosocial Care Centers of the Mental Health Networks of Belo Horizonte and Betim/MG. Observations were made of the psychiatrist’s activity, who were also interviewed in depth, as well as workers from other areas and patients. The general panorama pointed to controversies and discomforts regarding the work processes and the central place occupied by the psychiatrist and the medical staff in the absence of the clinical principles of treatment and decentralization of knowledge and powers advocated by the Brazilian Anti-Madhouse Fight and Psychiatric Reform. There was also a growing movement to institutionalize this service in the context of national Mental Health policies. ___ O presente artigo é resultante de uma pesquisa de mestrado desenvolvida na Universidade Federal de Minas Gerais (UFMG) no Programa de Pós-Graduação em Psicologia. Tem como objetivo geral compreender o que fazem os psiquiatras no Centro de Atenção Psicossocial (CAPS) quando trabalham entre o prescrito e o real. Em termos específicos, analisar como eles fazem uso de si e como mobilizam os seis Ingredientes de Competência (IGRs) da atividade no trabalho real. Por meio de princípios teórico- metodológicos da Psicossociologia do Trabalho, dialogando com a abordagem da Ergologia, realizamos uma pesquisa qualitativa em quatro Centros de Atenção Psicossocial das redes de Saúde Mental de Belo Horizonte e Betim/MG. Foram realizadas observações da atividade do psiquiatra, que também foram entrevistados em profundidade, além de trabalhadores de outras áreas e pacientes. O panorama geral encontrado apontou para controvérsias e desconfortos quanto aos processos de trabalho e ao lugar central ocupado pelo psiquiatra e pela medicina nas equipes à revelia dos princípios clínicos de tratamento e de descentralização de saberes e poderes preconizados pela Luta Antimanicomial e Reforma Psiquiátrica brasileiras. Observou-se também um crescente movimento de institucionalização desse serviço no cenário das políticas nacionais de Saúde Mental.

Based on theoretical studies about role (SARANGI, 2010, 2011a, 2011b; WEIZMAN, 1996, 2006, 2008) and positioning (LANGENHOVE and HARRÉ, 1999; WEIZMAN, 2008), this paper aims to analyse how roles and positions assignment and claims are interactionallly negotiated by participants of a debate interview. From a qualitative and interpretive approach, based on a case study, I use the contributions of Conversation Analysis (SACKS, SCHEGLOFF and JEFFERSON, 1974) as an analysis tool. The corpus consists of three editions of Roda Viva TV show that is characterized as an interviews show, in which various themes are raised and discussed by the participants that form the table in each of its editions. The analysis results show that the participants negotiate roles and positions, attributed and / or claimed, in the search for the defense of their points of view in the interaction.

In this work, we analyze an activity developed during Arnemann's research (2017) which focalized the informativity principle with students from nightly high school, verifying how the articulation between linguistic and epilinguistic activities contributes to obtain advances in the written production of argumentative genres. The theoretical referential presents authors of Text Linguistics (LT) with regard to informativity (BEAUGRANDE e DRESSLER, 1981; VAL, 1994), also adding authors of Information Science (CAPURRO e HJORLAND, 2007; CUNHA, 2001). Besides that, regarding the teaching and learning of Portuguese Language, we discuss about the approach, which gave support for the analysis, that prioritize the activities about the exercises (ENGSTRÖM, 2002), classifying them in: linguistics, epilinguistics and metalinguistics (FRANCHI, 2006; GERALDI, 1991; TRAVAGLIA, 1995). The results demonstrate advances regarding the informativity of the productions, which were mainly due to the articulation between procedures of linguistic nature (production and comprehension of textos) and epilinguistic (reflection from production).

This study aimed to understand the activity of the professionals of interdisciplinary teams in Psychosocial Care Centers (CAPS). Specifically, it was amied to highlight the collective dimension which the interdisciplinary work in these institutions consists. Therefore, the Psychodynamics of Work and Ergology were taken as the theoretical foundation of this research. The study was conducted with 19 professionals of three CAPS teams of a medium-sized municipality of Paraíba. A qualitative methodology was used through observation techniques and collective meetings discussion of the work activity. The results revealed that work in mental health and psychosocial perspective involves several situations such as variability of demand, different types of users, performed procedures, contact with families and requirements such as the need to share activities. In this sense, the collective dimension of interdisciplinary work strengthens the management of the activity, however it seems to be fundamental the empowerment of the work collective with a more effective group space.

The analysis of the activity of the railway conductors anchored in the theoretical contributions of ergonomics and ergology, showed how working conditions that cross the “routine on the rails” are painfulness in the daily lives of these professionals. An Ergonomic Work Analysis (AET) was conducted in 18 trips of cargo trains with 21 different conductors, in the stretch of the operation of a railroad in Belo Horizonte, Minas Gerais. This situation has raised us to a reflection on what is the painfulness at work? How circumscribe it and de ne it? What epistemological status to assign to this term? In which epistemic plan it could assume a statute of concept? Could it be associated with different levels of epistemicity? Which ones? And what political implications do we draw from this effort of theorizing from the working conditions analyzed in the daily routine of the operation of cargo trains on a Brazilian railroad, in Minas Gerais? The analysis confronted the empirical findings with the epistemic advances in several fields in the specialized literature, always analyzing critically the potential of the theoretical-methodological assumptions of Yves Schwartz ergological approach. This procedure revealed that the painfulness at work should be considered in epistemic dialogue, but with adherence to the activity. In this way… ___ A análise da atividade dos maquinistas ferroviários ancorada nos aportes teóricos da ergonomia e da ergologia, evidenciou como múltiplos condicionantes que cruzam a “rotina sobre os trilhos”, revelam-se como aspectos de penosidade no cotidiano destes profissionais. Foi desenvolvida uma Análise Ergonômica do Trabalho (AET), abordando 18 viagens de trens de carga com 21 maquinistas, no trecho da operação de uma ferrovia em Belo Horizonte, Minas Gerais. Situação que nos suscitou a uma reflexão sobre: o que é a penosidade no trabalho? Como circunscrevê-la e defini-la? Qual estatuto epistemológico atribuir a este termo? Poderia ele assumir um estatuto de conceito em que plano epistêmico? Poderia ser associada a diferentes níveis de epistemicidade? Quais? E que implicações políticas retirar deste esforço de teorização à partir das condições de trabalho investigadas na rotina diária da operação de trens de carga, numa ferrovia Brasileira, em Minas Gerais? A análise confrontou os achados empíricos com os avanços epistêmicos em vários campos na literatura especializada, sempre analisando criticamente o potencial das formulações encontradas com base nos pressupostos teórico-metodológicos de Yves Schwartz da abordagem ergológica. Este procedimento indicou que a penosidade no trabalho deve ser pensada em diálogo epistêmico, mas com aderência à atividade… ___ Ancrée dans le cadre théorique de l’ergonomie et de l’ergologie, notre analyse de l’activité des conducteurs de train a montré comment les contraintes multiples qui traversent la “routine sur les rails” illustrent des aspects de la pénibilité quotidienne de ces professionnels. Dans une première phase, l’Analyse Ergonomique du Travail (AET) a permis de suivre 18 voyages de trains de marchandises menés par 21 conducteurs d’un chemin de fer à Belo Horizonte, Minas Gerais. A partir des données recueillies, notre réflexion a évolué concernant les questions suivantes : Qu’est-ce que la pénibilité au travail? Comment peut-on la circonscrire et la définir? Quel statut épistémologique attribuer à ce terme? Pourrait-il être compris en tant que concept et à quel niveau épistémique? Pourrait-il être associé à différents niveaux d’épistémicité? Lesquels? Mais aussi: quelles portées politiques peut-on déduire de cet essai de théorisation à partir des conditions de travail étudiées dans la routine quotidienne de la conduite de trains de marchandises d’un chemin de fer brésilien de l’État de Minas Gerais? L’analyse a confronté les résultats de la recherche empirique avec les progrès épistémiques enregistrés au sein de différents champs de la littérature spécialisée, en maintenant un regard critique sur le potentiel des formulations énoncées sur base des hypothèses théoriques et méthodologiques de l’approche en ergologie de Yves Schwartz. Nous avons ainsi mis en évidence que la pénibilité au travail doit être considérée dans le cadre d’un dialogue épistémique, sans ne jamais oublier l’activité…

In order to investigate the performance quality of routine measurements of Nuclear Medicine Services (NMS), the National Metrology Laboratory of Ionizing Radiation/Institute of Radiation Protection and Dosimetry (LNMRI/IRD) has been conducting, since 1998, a program of comparison for activity measurements of radiopharmaceuticals administered to patients in nuclear medicine. Correction factors are determined from the result of performance analysis in order to determine with better accuracy the activity to be administered to the patients.

The aim of this study was to verify the activity period, the frequency of behavioral acts through basic ethogram and the influence of temperature and the relative air humidity on behavior of Achatina fulica Bowdich, 1822 and Megalobulimus oblongus (Müller, 1774). Both species presented nocturnal activity. The most frequent behavioral acts were "Rest", "Buried" and "Feed" for both species. Megalobulimus oblongus was less active than the alien species, but presented a higher feeding frequency. The increasing temperature caused reduction in activity on both species while the increase in humidity influenced only A. fulica. Despite the native species being less susceptible to changes in temperature and humidity and fed more than the alien species, the biological and ecological features of A. fulica, as its great reproductive potential and the absence of natural predators, make this species an efficient competitor, with potential to extinct the populations of M.oblongus.

This article proposes a theoretical discussion on competences in the public service based on the ergological perspective and according to Zarifian's sociological contribution. Ergology emphasizes the importance of criticizing the simplification of the measurement of competences, by suggesting an approach to acting in competence that is based on ingredients. Zarifian introduces the concept of service relationship, which is understood as a transformation in the conditions of a user's activity upon his needs. Both approaches imply the need for a competence management centered on the point of view of activity and are critical of a management that excludes workers from decisions about their work.

This paper proposes a discussion about the centrality of language to carry out the work activities in specific contexts of legal work, situated in criminal spheres. The concepts of discursive practice and activity are mobilized to question the institutional order of the legal work, the debate of the rules that the subject performs in the execution of his labour and the production of text as listening place of his investments in the discursive and working order. Analyzing the composition of reports of a police investigation, we search to understand the process of discursive mediation in the documents that is supposed to be records of actual facts. We understand that this link between the postulates of discourse analysis and Ergology reveals the contribution of linguistics to consider issues relating to the processes of (re) production of the work and the contribution of Ergology to consider issues relating to historical and political determinations on the process of production of meaning.

Two paradoxes seem to appear throughout Alain Wisner’s Anthropotechnology. The first one, from his studies on human labour, leads him to assert that all human beings have equal potentialities, while maintaining at the same time that this universality emerges through history and inheritance which are always specific. The second one leads him to request the cooperation of various areas of human sciences, but without a critical approach, as if they could disregard the consequences of the first paradox.Firstly, it is suggested how it is possible, through the ergological approach, to clear up the first paradox by going deeper into this concept of activity, largely inherited from the wisnerian ergonomy. From an anthropological point of view, it is possible to define live as a universal effort for partly redesigning the frame of local norms which surround human beings and groups.Secondly, the question is : through which crucial scenes the «setting in history» of this universality is developed? Three knots of this « setting in history » are successively considered: body, technical activity and social building of the various spaces where living together proved efficient.In accordance with these points, the basis for a treatment of the second paradox seem yet to be given: if human activity is a permanent crucible for « renormalisations », it constantly reproduces social configurations so that concepts and categories of the human sciences are always partly unprepared in regard to them. Then the question is: how this concept of activity which runs across them all is refracted or taken into account by these sciences? To conclude: if this paper entirely assumes the first paradox, it cannot accept the second one.

This text aims to present the embarrassments experienced by authors at the time of writing their thesis and dissertation. The object of the studies here introduced were “the writing of college course conclusion monographs, experienced by working undergraduates” and “the mediation between invested and academic knowledge of working students from a course that is complementary to elementary education”. These were developed in the Ergology Department of Aix-Marseille University, under the guidance of Yves Schwartz. By making use of self-confrontation into invested knowledge to collect the data of the research, the authors confronted their own knowledge disinvested by the writing activity and transformed into academic knowledge. Ergology enables one to situate the notion of writing as a complex activity particular to humans. For Goody, writing promotes profound changes in societies in the same way it promotes changes in the body-self, since the one who writes is the one to experience the dramatic points of the use of the self by the self and by others, which originate from the movement between the background of the academic writing standards and the standards of the Academy itself, the infidelity of the medium and the necessities of restandardizing unique writing activities. ___ Este texto tem como objetivo apresentar os embaraços vivenciados por seus autores por ocasião da escrita, respectivamente, da dissertação e da tese. Os objetos de estudo das pesquisas aqui apresentadas foram: “a atividade de escrita de monografias de conclusão de um curso superior, vivenciada por trabalhadores-universitários” e “a mediação entre saberes investidos e constituídos de trabalhadoras- estudantes de um curso de complementação do Ensino Fundamental”. Trata-se de duas pesquisas desenvolvidas no Departamento de Ergologia da Universidade de Aix-Marseille, sob orientação de Yves Schwartz. Ao fazerem uso da autoconfrontação ao saber investido para coletar os dados da pesquisa, os autores se confrontavam com seus próprios saberes desinvestidos pela atividade de escrita e transformados em saberes constituídos. A ergologia permite situar a noção de escrita como uma atividade complexa própria do humano. Para Goody, a escrita promove mudanças profundas nas sociedades, da mesma forma que essa atividade promove mudanças no corpo-si, porque aquele que escreve vivencia dramáticas do uso de si por si mesmo e pelos outros. Essas dramáticas são originárias do movimento entre as normas antecedentes da escrita, da academia e as suas próprias normas, a infidelidade do meio e as necessidades de renormatização das atividades singulares de escrita.

As part of a doctoral research, this article aims to contribute to the construction of the of invested knowledge notion, developed by the Department of Ergology. It is considered that the activity is even the movement of the genesis of knowledge; calls the notion of activity, consciousness and memory, philosophy of life and theory of relationship with knowledge. It is argued that this knowledge is not always revealed to the body-itself, it can also be unconscious for this needs to be recovered to be placed in relation to the knowledge set up to be accessed by others, which will give it the status of academic knowledge. States that constituted knowledge is always provisional because it is always in gap with the knowledge invested in the body-itself by the activity. It concludes with the formulation of a problem of the "Know Invested" because when one know has just been systematized or achieve the status of constituted knowledge it triggers internal processes that will generate other invested knowledge, successively. ___ No quadro de uma pesquisa de doutorado, este artigo se propõe a colaborar para a construção da noção de saber investido, desenvolvida pelo Departamento de Ergologia. Considera-se que a atividade é mesmo o movimento da gênese do saber, convoca a noção de atividade, de consciência e memória, a filosofia da vida e a teoria da relação com o saber. Argumenta-se que esse saber nem sempre é revelado ao corpo-si, pois pode ser também inconsciente, por isto necessita ser recuperado para ser colocado em relação com os saberes constituídos para ser acessado por outras pessoas, que lhe conferirão o estatuto de saber acadêmico. Afirma que o saber constituído é sempre provisório porque ele sempre está em defasagem em relação ao saber investido no corpo-si pela atividade. Termina-se com a formulação de uma problemática do "Saber Investido", pois, quando um saber acaba de ser sistematizado ou atingir o status de saber constituído, ele desencadeia processos internos que irão gerar outros saberes investidos, assim sucessivamente.
