Digitalisierung der öffentlichen Verwaltung aus Sicht der IT-Beschaffung
Authors: Schlimme OIiver
Published: November 2021

Die Digitalisierung der Gesellschaft hat auch die öffentliche Verwaltung erreicht. Gesetzliche Vorgaben setzen einen engen Zeitplan, um die digitalen Services für die Bürgerinnen und Bürger in wenigen Jahren zu etablieren.

Die Projekte sind hochkomplex und das Marktinteresse ist aufgrund der aufgerufenen Auftragssummen entsprechend hoch. Mit der letzten Reform des Vergaberechts im Jahr 2016 wurden neue Methoden etabliert, die im Zuge der Digitalisierung einen Nutzen entfalten können. Dennoch bleibt das Vergaberecht in einigen Bereichen widersprüchlich. Die Vergabestellen als ausführende Instanz müssen den Einzelfall zunehmend intensiver werten und immanente Spannungsfelder mit den Digitalisierungsprojekten auflösen. Die Arbeit wirft einen praktischen Blick auf die hiermit verbundenen Herausforderungen und Probleme für das Beschaffungswesen, der Schwerpunkt liegt hierbei auf der Beschaffung von Waren- und Dienstleistungen im Bereich des EU-Vergaberechts. Praktische Handlungsempfehlungen, die es der Vergabestelle ermöglichen, in wirtschaftlicher, organisatorischer, aber auch taktischer Sicht auf die sich ändernde Beschaffungswelt zu reagieren, runden das Werk ab.

Landslide Inventory, Susceptibility, Hazard and Risk Mapping
Authors: Wubalem Azemeraw
Published: November 2021

Landslide is that the downslope movement of debris, rocks, or earth material under the influence of the force of gravity. Although the causes and mechanisms of landslides are complicated, human action, earthquakes, and severe rainfall can trigger them. It can happen when the driving force surpasses the resisting force due to natural soil or rock slope destabilization. Landslide is one of the foremost destructive and dangerous natural hazards that cause numerous fatalities and economic losses worldwide. Therefore, landslide investigation, susceptibility, hazard, and risk mapping are vital tasks to disaster loss reduction and performance as a suggestion for sustainable land use planning. The determination of the cause variables, identification of existing landslides, and production of a landslide susceptibility, hazard, and risk map are all necessary steps in the mitigation of landslide incidence on the globe. Landslide susceptibility, hazard, and risk maps are the outcome of a statistical relationship between environmental conditions and previously occurring landslides. It provides critical scientific support for the government’s reaction to land use practices and the management of landslide threats. The type, concept of landslides, factor, inventories, susceptibility, hazard, and risk, as well as mapping and validation methodologies, have all been examined in this chapter. The distinction between landslide susceptibility and hazard has surely been debated.

Published: November 2021

In the autumn of 2014, we conducted a malacological survey at 23 freshwater bodies in the Danubian lowland, SW Slovakia. We aimed to conduct a malacological inventory of semi-natural sites of a high conservation value. During the fieldwork, we used conventional methods of sampling; mostly sweeping by a hemispherical metal kitchen strainer from both natant and submerged vegetation and also from bottom sediments. At each site, ten people have collected molluscs for 60 to 90 minutes (except site No. 3, 5 and 15 – 1 person/2 hrs.). During the sampling we did not use any destructive methods. A total of 67 species were found in the whole surveyed territory (43 gastropods, 24 bivalves), which is the complete current species richness of the aquatic mollusc fauna in the Danubian lowland. The most species rich sites include the Číčovské rameno Oxbow lake (36 species, No. 2), Klátovské rameno Side arm (32 spp., No. 10) and Parížske močiare Swamp (24 spp., No. 11). Bithynia tentaculata and Planorbarius corneus were the most frequent species (i.e. found at +65% of sites) and the following eight species were recorded at 44–52% of sites (i.e. 10–12 individual sites; given in a descending order): Anisus vortex, Lymnaea stagnalis, Planorbis planorbis, Anisus vorticulus, Bithynia leachii, Stagnicola palustris, Viviparus acerosus and V. contectus. In contrast, Bithynia transsilvanica, Gyraulus riparius, Pisidium personatum, Planorbis carinatus, Sphaerium nucleus and Valvata macrostoma were found at only one site (species recorded only in flood debris of the Danube River were not considered).
Měkkýši přírodní rezervace Hutě a jejího okolí v CHKO Bílé Karpaty [Molluscs of the Hutě Nature Reserve and its surroundings in the White Carpathians PLA]
Authors: Coufal Radovan , Horsák Michal
Published: November 2021

The Hutě Nature Reserve is located in the central eastern part of the White Carpathians PLA, near the Žítková village. The reserve protects a preserved and topographically heterogeneous area composed of forest groves, meadows, pastures, and spring fens with a high diversity of submontane and thermophilic plant and animal assemblages. The species composition of molluscs (9 out of 10 ecological groups represented) consists mainly of woodland dwellers, which account for the majority of species diversity (30 spp.; 52%), followed by ubiquitous (9; 16%), hygrophilous (5; 9%), hygrophilous woodland dwellers (4; 7%), aquatic (4; 7%) and open-habitat dwellers (3; 5%). Vertigo moulinsiana (EN), internationally protected under Annex II of the EU Habitats Directive, Daudebardia brevipes (VU), Ambigolimax nyctelius (NT), Orcula dolium (NT) and Bythinella austriaca (NT) are species of conservation concern. To retain favourable habitat conservation status, the spring fens with V. moulinsiana occurrence must be managed extensively by grazing or mowing, while the forests must remain in a non-intervention regime.

Sleep state misperception: is there a CNS structural source?
Authors: Truzzi Giselle de Martin , Teixeira Igor de Lima , Prado Lucila Bizari Fernandes do , Prado Gilmar Fernandes do , Tufik Sergio , Coelho Fernando Morgadinho
Published: November 2021

Introduction: We describe a case of sleep state misperception in a patient with a neurotoxoplasmosis lesion in the left nucleocapsular region.

Case report: A 40-year-old female patient presented relating sleeplessness over the past 2 years, concurrent with progressive headaches, dizziness and motor and sensory deficits in the right upper and lower limbs. She had a history of AIDS, on irregular antiretroviral therapy and neurotoxoplasmosis. A polysomnography confirmed the hypothesis of sleep state misperception, and magnetic resonance imaging revealed a residual lesion in the left nucleocapsular region.

Conclusion: Different models consider that the sleep state misperception could be correlated to structural abnormalities of the central nervous system. A recent study showed that the medial prefrontal cortex had a lower activation in patients with unrefreshing sleep due to chronic fatigue syndrome. This case report highlights the possibility of sleep state misperception having - at least partially - an anatomical substrate in the left nucleocapsular region.
Self-reported current sleep behaviors of adult athletes from different competitive levels and sports
Authors: Randell Rebecca K , Anderson Rosie , Carter James M , Rollo Ian
Published: November 2021

Objectives: To quantify self-reported current sleep behaviors in a range of adult athletes. In addition, to determine any differences in sleep duration and sleep quality, depending on sport type and competitive level.

Material and Methods: In this cross-sectional study, 313 athletes (243 male, 70 female), competing in a variety of sports and competitive level, completed the Pittsburgh sleep quality index (PSQI) and a questionnaire which captured current sleep behaviors. Sleep quality was calculated using the global PSQI score (≥ 5 indicative of poor sleep quality).

Results: On average, athletes self-reported sleep duration was 7:34 ± 1:00 h:min. Overall, 19% of athletes achieved less than 7 h of sleep, 50% achieved less than 8 h. Global PSQI score was 5.0 ± 2.4, with poor sleep quality found in 55% of athletes. Sleep duration was significantly shorter in runners compared to basketball, soccer and rugby players (p < 0.05). Recreational athletes slept significantly less (7:08 ± 0:54 h:min) than competitive (7:32 ± 1:00 h:min), national (7:50 ± 1:00 h:min) and elite level athletes (7:49 ± 0:51 h:min). No differences in sleep quality were found between sport or competitive level.

Discussion: Half of the athletes failed to achieve 8 h of sleep per night and the majority reported compromised sleep quality. Sport type and competitive level may influence sleep duration; however, these factors do not seem to cause discrepancies in sleep quality. This study provides novel data into the sleep behaviors of adult athletes, and suggests strategies to improve sleep duration and quality may be warranted.

Authors: Islam Zohurul , Hsan Kamrul , Islam Saiful , Gozal David , Hossain Mahfuz
Published: November 2021

Objectives: Problematic internet use (PIU) is a major behavioral problem that has been closely associated with poor sleep quality in many different countries, but is poorly studied in Bangladesh. This study was conducted to investigate the sleep quality and its association with PIU among university students in Bangladesh.

Material and Methods: A cross-sectional study was conducted between May 2019 and December 2019 among 400 students attending four public universities in Bangladesh. The Pittsburgh sleep quality index (PSQI) was used to determine sleep quality and Young’s internet addiction test (IAT) was used to describe the degree of PIU.

Results: A significant negative association emerged between good sleep quality and PIU (p<0.001). In the multivariate logistic regression, students having PIU were 0.28 folds less likely to have good sleep quality (AOR: 0.28, 95%CI=0.18-0.43, p<0.001) when compared to non-PIU students. In addition, significant associations between sleep quality and socio-demographic and lifestyle factors were identified.

Conclusion: Implementation of an effective awareness program and development of education strategies are required to reduce internet addictive behaviors and improve sleep quality among Bangladeshi university students.

Published: November 2021

Introduction: In the COVID-19 pandemic, physical and psychological health are of immense concern for the governing bodies and health policymakers in the period of lockdown and self-isolation. An in-depth analysis is required to recognize the changes in mental health among the public of different geographical areas.

Objective: The study aimed to investigate the sleep quality and anxiety among the population in Saudi Arabia during the lockdown period from March to June 2020.

Material and Methods: We conducted a cross-sectional study and surveyed the population in Saudi Arabia during the lockdown. We analyzed the anxiety and sleep quality in a population with variable socio-demographic profiles. We assessed anxiety using the self-rating anxiety scale (SAS) questionnaire and tested the sleep quality by using the Pittsburgh sleep quality index (PSQI) questionnaire. We analysed the questionnaire responses to determine the relationships between anxiety, stress, sleep disturbances by using SPSS, and considered the p-value<0.05 statistically significant.

Results: We collected 397 questionnaires from the participants. The respondents were mostly of youth age (19-24 years), 66.5% of respondents were male, while there were 33.5% females. Most of the participants did not contact any COVID-19 patients (75.1%, n=298). The finding revealed that most people did not consider associated anxiety as a worrying disorder as the vast majority were normal with only 12.6% had mild-to-moderate anxiety and almost 1% had moderate-to-severe anxiety. While correlating the sleep patterns disturbance in individuals who had contact with COVID-19 patients, there was a significant sleep disturbance. The disturbance of sleep was in having problems falling sleep (p-value=0.024), having bad/horrible dreams (p-value=0.017), feeling cold at sleeping (p-value=0.038), and difficulty staying active during eating or driving (p-value=0.012). There was a significant correlation with anxiety related to the COVID-19 contact and problems affecting the routine work (p-value=0.001).

Conclusion: There is a significant correlation with anxiety related to the contact with COVID-19 positive patients and problems affecting the routine work among operational professionals. The sleep quality is poor due to the stay-at-home order, having a disorganized working schedule, and deprived lifestyle. The awareness regarding the publics’ mental health related to the pandemic needs to be implemented and psychological guidelines ought to be available for the public. Health measures through the promotion of lifestyle modifications, mindful body practices, meditation, and home exercise can reduce stress and improve the quality of sleep.

Published: November 2021

Adolescence is a phase with physiological and behavioral changes. One of them occurs in the sleep-wake cycle pattern, manifested by a phase delay. However, morning school start time can decrease sleep duration during weekdays, impairing adolescent cognitive performance and well-being. Adolescents of different ages and educational level might suffer the impact of academic demand on sleep-wake cycle and cognition differently. Thus, the aim of this study is to compare the sleep habits and quality, sleepiness upon awakening and attention components among adolescents in the first years of high school and college. 71 adolescents participated in the study (45 girls and 26 boys), 44 enrolled in high school morning classes (G1 - 15.5±0.7 years), from a private school, and 27 college students enrolled in morning classes (G2 - 18.8±1.04 years), from biosciences courses from a public institution. The groups did not differ in bedtime, get up time, time in bed and sleep irregularity. However, both groups showed differences according to the day of the week, bedtime and get up time became later and time in bed extended on weekends. G1 presented worse sleep quality and regarding attention, showed higher percentage of omissions in all components and worse performance in sustained attention (ANOVA, p<0.05). The poorer sleep quality of high school adolescents and reduced attention may have a negative effect on school performance. Additional studies are needed to investigate the causes of these differences between these two educational levels.

This document “Proposed management model for the use of telemonitoring to positive airway pressure adherence” was prepared by a special commission of the Brazilian Association of Sleep Medicine, with the objective of recommending a follow-up model for patients undergoing positive airway pressure therapy using telemonitoring. This proposal was prepared based on a survey and analysis of the most up-to-date national and international literature and uses the best available evidence to facilitate the standardization of care by Sleep Science specialists with potential benefit for patients. Among the conclusions of the document, it is emphasized that telemonitoring is an important tool that allows health professionals trained in sleep-disordered breathing to remotely monitor PAP therapy, allowing prompt and, when necessary, daily adjustments to be made in order to increase adherence to treatment. The authors also conclude that the privacy of the data received and shared during the provision of telemonitoring must be respected by the physician or health professional trained in sleep, with the authorization of the patient and/or person responsible, who should be made aware of the short-, medium- and long-term provision of the service.

Published: November 2021

Objective: To investigate the prevalence of insomnia and its different phenotypes as well as their association with fear of COVID-19 in the general population.

Material and Methods: This was a cross-sectional study conducted using an online survey (e-poll). All available participants who completed the online survey form were included in the current study. All individuals with a history of sleep problems were excluded. A questionnaire package consisted of insomnia severity index (ISI), and FCV-19 for corona fear was administered for all participants. Insomnia was defined as ISI≥8. Insomnia phenotypes were considered as: (a) DIS: difficulty initiating sleep; (b) DMS: difficulty maintaining sleep; (c) EMA: early morning awakening; and (d) combined insomnia.

Results: A total of 1,223 participants [827 (67.6%) female, mean age=39.82±10.75 years old], enrolled in the current survey. Based on ISI, 675 (55.2% [95%CI=52.40-57.98]) were categorized into the insomnia group. Insomnia was more prevalent in females (p=0.006), participants with 50 years old or higher (p=0.04), or high fear of COVID-19 (p<0.0001). Totally, 67.4%, 66.4%, and 55% of all participants had DIS, DMS, and EMA, respectively, in the current outbreak. Besides, 79% had impaired daily functioning, 51.6% had impaired quality of life, and 62% were worried about their sleep problem. Notably that a considerable percentage of individuals with normal ISI scores had at least one insomnia phenotype or impaired daily functioning and quality of life. Further analyses revealed a significant increasing trend in all four insomnia phenotypes prevalence with an increase in fear of COVID-19 (all p-values<0.0001).

Conclusion: Individuals with higher age, female gender, or higher fear of COVID-19 are at higher risk of all types of insomnia as well as impaired daytime performance or quality of life.

Published: November 2021

Both non-epileptic sleep disturbances and epilepsy are common in patients with mucopolysaccharidoses (MPS), so diagnosis of sleep-related hypermotor epilepsy in these patients is a tackling issue. We present a case of an adult patient with MPS IIIB (Sanfilippo syndrome), who presented with numerous nocturnal events of sudden awakening and hypermotor behavior, which had been previously regarded as parasomnias. Overnight video-EEG captured numerous stereotypical seizures with ictal pattern in the frontal regions, which led the diagnosis of SHE. The patient was started with carbamazepine, which resulted in a substantial reduction in the number of seizures. Our report provides further support for use of overnight video-EEG in the differential diagnosis of sleep-related disorders in MPS, yet true incidence of SHE in MPS patients remains unknown.

Published: November 2021

Background/Aims: Endoscopic visualization of the microscopic anatomy can facilitate the real-time diagnosis of pancreatobiliary disorders and provide guidance for treatment. This study aimed to review the technique, image classification, and diagnostic performance of confocal laser endomicroscopy (CLE).Methods: We conducted a systematic review of CLE in pancreatic and biliary ducts of humans, and have provided a narrative of the technique, image classification, diagnostic performance, ongoing research, and limitations.Results: Probe-based CLE differentiates malignant from benign biliary strictures (sensitivity, ≥89%; specificity, ≥61%). Needlebased CLE differentiates mucinous from non-mucinous pancreatic cysts (sensitivity, 59%; specificity, ≥94%) and identifies dysplasia. Pancreatitis may develop in 2-7% of pancreatic cyst cases. Needle-based CLE has potential applications in adenocarcinoma, neuroendocrine tumors, and pancreatitis (chronic or autoimmune). Costs, catheter lifespan, endoscopist training, and interobserver variability are challenges for routine utilization.Conclusions: CLE reveals microscopic pancreatobiliary system anatomy with adequate specificity and sensitivity. Reducing costs and simplifying image interpretation will promote utilization by advanced endoscopists.

This report documents an experimental program designed to investigate High Energy Arcing Fault (HEAF) phenomena for medium voltage electrical switchgear containing aluminum conductors. This report covers full-scale laboratory experiments using representative nuclear power plant (NPP) three-phase electrical equipment. Electrical, thermal, and pressure data were recorded for each test and documented in this report. This report covers four of the fourteen planned medium voltage electrical enclosure tests. Subsequent reports will document the additional tests performed in the future. The experiments were performed at KEMA Labs located in Chalfont, Pennsylvania. The experimental design, setup, and execution were completed by staff from the United States Nuclear Regulatory Commission (NRC), the National Institute of Standards and Technology (NIST), Sandia National Laboratories (SNL) and KEMA. In addition, representatives from the Electric Power Research Institute (EPRI) observed some of the test setup and execution. The HEAF tests were performed on four near-identical units of General Electric metal-clad medium voltage switchgear. The three-phase arcing fault was initiated on the primary cable connection bus. All four tests used the same system voltage (6.9 kV) but varied the current and duration. Real-time electrical operating conditions, including voltage, current and frequency, were measured during the experiments. Heat fluxes and incident energies were measured with plate thermometers and slug calorimeters at various locations around the electrical enclosures. Internal enclosure pressures were measured during the experiments. The experiments were documented with normal and high-speed videography, infrared imaging and photography. Insights from this testing included timing information related to enclosure breach, event progression, mass loss measurements for electrodes and steel enclosures, peak pressure rise, particle analysis, along with visual and thermal imaging data to better understand and characterize the hazard. These results will be used in subsequent efforts to advance the state of knowledge related to HEAF.
SUSTAINABILITY AND THE CONCEPT OF SHARED VALUE AND THE 4TH INDUSTRIAL REVOLUTION: A BIBLIOMETRIC ANALYSIS OF TWO SCIENTIFIC NETWORKS
Authors: de Wet Inge , Imke de Kock
Published: November 2021

The role of the technologies, concepts, and philosophies associated with the Fourth Industrial Revolution (4IR) has been argued to hold significant value in the quest for sustainability. Furthermore, the concept of ‘shared value’ has been put forward as an approach that holds significant value when aiming to bring about socially just, economically fair, and environmentally friendly production and consumption practices. The importance of the link between the concept of shared value and 4IR is explored in this paper using bibliometric analysis, and we expose the different structures of these fields, including keywords, key authors, and the coherence of these two scientific networks in order to uncover areas of integration between them. The findings of this analysis indicate that a clear gap in integration exists; and the opportunity for research in this field could further contribute to the debate on using innovative, contemporary technologies — such as those associated with 4IR — to support approaches to ensure increasingly sustainable business practices, such as shared value.
TOWARDS A RELATIONAL FRAMEWORK OF DESIGN
Authors: Tladi Bontle , Mokgohloa Kgabo , Bignotti A
Published: November 2021

The evolution of design has seen shifts towards more co-creation-based practice. This is not an entirely new development, as there has been a growing recognition and adoption of user-centred themes and terms such as co-design and human-centred design, among others. The ways of ‘doing’ such practices are becoming well-documented and presented through various tools and techniques; however, what kind of ‘being’ supports this? The paper reviews indigenous research methodologies (IRM) to propose the dimensions of a more relational framework of design. It reviews the 4Rs of indigenous research methodologies to propose five areas (expanded into eight dimensions) for a more relational framework of design. These dimensions can also support a way of ‘being’ that can guide the approach towards more co-creative thought and practice when ‘doing’ design. These dimensions can further support efforts to understand and to develop approaches that respond to the decolonisation and indigenisation of the design process.

Historically, the maintenance function of an organisation was viewed as a ‘necessary evil’; however, the view has shifted to seeing it as a strategic element within an organisation to accomplish its business objectives. For organisations to continue to be competitive, they need to harness the true potential of their people by evaluating ways for maintenance teams to achieve effective teamwork. In the light of this, the study was tailored to determine the factors that characterise high-performing maintenance teams in the petrochemical industry in South Africa. The study determined an importance ranking of these critical factors when implementing high-performance maintenance teams. A questionnaire was used to gather quantitative data from 69 respondents. Analysis of the data revealed that the most important factors for maintenance teams to achieve high performance were knowledge and motivation. It was also found that the most important performance indicators for maintenance were equipment availability, overall equipment effectiveness, and spares availability.

“A doctor can save maybe a few hundred lives in a lifetime. A researcher can save the whole world.” - Craig Venter This annual Special Edition once again combines outstanding papers from two conferences: The 32nd annual conference of the Southern African Institute for Industrial Engineering (SAIIE32) (4-6 October 2021, held in Muldersdrift, South Africa), The 22nd annual international conference of the Rapid Product Development Association of South Africa (RAPDASA) (3-5 November 2021, held in Pretoria, South Africa). After the first on-line conferences in 2020 due to COVID-19 regulations, it was excellent to see a return to some normality in 2021 – both these conferences were physical, and the participants were truly hungry for the physical networking opportunities. The Special Edition, introduced in 2016, continues to showcase the best research presented at these conferences. Papers undergo the same double-blind peer review process using the journal’s criteria; and the choice of those included in this Special Edition was based on rankings provided by the reviewers and on a final check of their quality and suitability by the editors of the journal. It was interesting to notice that, in 2020, both conferences focused on the road ahead after the period of uncertainty, with the following two themes: SAIIE32: Steps, and RAPDASA: Industry 4.0 – Digital manufacturing industrializing Africa. It demonstrates the resilience of humankind, and the drive to move forward. For this very reason, the feature article as selected by the chief editor, was authored by young Industrial Engineers, looking forward at what the future may hold, with the title: “Beyond The Industrial Engineering Frontier: A Few Steps In History And A Giant Leap Into The Future”. Although industrial engineers are a relatively small community of professionals, I am always inspired by the relevant, innovative, and far-reaching impact that we can have on every aspect of our society. As you read through the papers in this Special Edition, I trust that you will be inspired by the exemplary work that represents our discipline of industrial engineering. Teresa Hattingh Guest editor
Comment mourir si la mort est planifiée ?
Authors: van der Geest Sjaak , Fortin Sylvie
Published: November 2021

Cet essai examine deux changements importants que subissent le mourir et la mort dans le monde pluriforme et sécularisé d’aujourd’hui. Le premier changement met en scène l’autonomie, les souhaits d’autonomie nourris pendant la vie s’étendant désormais au moment et à la manière de mourir. L’euthanasie permet à une personne d’éviter la condition douloureuse et difficile qui précède la fin de vie. Un second changement majeur est que ceux qui meurent et ceux qui restent peuvent nourrir des croyances et des attentes différentes concernant ce qui se passe au moment de la mort et après. Dans le monde chrétien, par exemple, les rituels plutôt uniformes qui étaient pratiqués avant et après la mort ne reflètent plus les croyances d’un grand nombre de personnes confrontées à la mort aujourd’hui. Ce bref essai explore l’imbrication de ces deux évolutions relatives à la mort et au mourir dans la société actuelle, en mettant l’accent sur le pays de l’auteur, les Pays-Bas.
Prise de décision en fin de vie
Authors: Fortin Sylvie , Lessard Sabrina
Published: November 2021

La vie et la mort sont étroitement liées en milieux de soins où les questions nombreuses en regard (notamment) de la qualité de vie et de mort, de la poursuite ou de l’arrêt du traitement et de la légitimité des personnes qui prennent part aux décisions façonneront ces moments cruciaux. Devant de nombreux possibles thérapeutiques, quand s’arrêter ou encore quand tendre vers une perspective palliative n’est jamais donné d’emblée. Les frontières entre les catégorisations sociales séparant le curable de l’incurable, le malade du mourant et la compréhension de l’imminence de la mort restent parfois incertaines ou à reconstruire selon les cas. À partir de deux études ethnographiques (observations en unités de soins, entretiens avec soignants, patients et leurs familles), l’une menée en contexte pédiatrique hospitalier (unité d’hématologie-oncologie-greffe de moelle osseuse) et l’autre auprès de personnes de grand âge en milieu hospitalier et en centre d’hébergement et de soins de longue durée à Montréal, les auteures discutent de la diversité des trajectoires de fin de vie. Quand peut-on s’arrêter ? Qui peut répondre ? Ces questions sont récurrentes sans être nouvelles. Elles demeurent néanmoins le quotidien de la « grande maladie ». Les auteures puiseront à même le « prendre soin » et le « devoir de non-abandon » pour dégager quelques éléments de réponse tout en s’interrogeant sur le statut contemporain de la (bio)médecine (entre espoirs et tensions) et les ambigüités conceptuelles et empiriques entre le « curatif » et le « palliatif ».
Une mort lente
Authors: Soulières Maryse
Published: November 2021

Cet article s’appuie sur une recherche doctorale ethnographique échelonnée sur 18 mois et effectuée auprès de résidents atteints de troubles neurocognitifs majeurs (de type Alzheimer ou autre) dans deux centres d’hébergement et de soins de longue durée (CHSLD) à Montréal. Les données sont tirées de plus de 200 heures d’observation auprès de résidents (n=8) au dernier stade de la maladie (grabataires et ayant perdu l’usage de la parole), de photographies ainsi que d’entretiens (n=20) auprès de proches et de membres du personnel. Cette incursion dans l’univers des pertes cognitives sévères, alors que les personnes concernées ne sont plus en mesure d’exprimer elles-mêmes leurs besoins et leurs volontés, révèle la longue attente d’une mort imprévisible bien que toujours présente en filigrane, et parfois espérée. Elle met en lumière un rapport à la mort et à la fin de vie marqué par un sentiment d’impuissance et d’ambivalence, alors que les proches et le personnel peinent à faire sens de la condition actuelle et de la vie de ces résidents. L’article permet d’explorer le brouillage du statut de « vivant » qui s’opère dans ce contexte singulier de fin de vie, apportant une contribution novatrice aux réflexions québécoises entourant l’accès à l’aide médicale à mourir pour les personnes inaptes.
Soignants et étudiants face à la mort
Authors: Foley Rose-Anna , Saraga Michael
Published: November 2021

À partir d’un séminaire destiné aux étudiants en médecine intituléSoignants face à la mortet de nos propres travaux en ethnographie hospitalière et dans le champ de la psychiatrie de liaison dans un hôpital général, nous discutons le statut des émotions dans les soins. Interrogés sur la fin de vie par nos groupes d’étudiants, les soignants décrivent souvent les émotions comme dangereuses et l’importance de s’en prémunir comme primordiale. À partir de ce constat et d’une certaine ambivalence décrite par les étudiants, nous revenons sur la place des émotions dans la littérature biomédicale et en sciences sociales. Les émotions suscitant l’intérêt des sciences sociales sont surtout celles des patients et les décisions cliniques sont le plus souvent envisagées comme étant contraintes par des valeurs et des normes imposées aux soignants, eux-mêmes sans émotion apparente. Cette posture redouble ainsi curieusement l’idée, répandue dans les soins et plus généralement dans nos sociétés, selon laquelle les émotions risquent de mettre à mal la capacité à penser de manière rationnelle et objective et doivent être mises à l’écart. Or, en sciences sociales et notamment en ethnographie, les émotions des chercheurs sont perçues comme de fidèles indicateurs ; de même, dans les soins, les travaux du psychanalyste Michael Balint insistent sur la nécessité d’une prise en compte par les cliniciens des émotions suscitées par les patients. Sur cette base, il serait pertinent de redonner aux émotions une place centrale pour guider les actions des chercheurs comme des cliniciens.
Espiritualidade ecológica integral a partir dos povos indígenas
Authors: Ribeiro Antônio Lopes
Published: November 2021

Em um contexto em que a humanidade se desintegra rapidamente, a sustentabilidade da vida no planeta constitui uma necessidade e finalidade primária, para a qual convergem as religiões mundiais. Isto faz com que as religiões se aproximem, consolidando-se cada vez mais a consciência de que habitamos uma casa comum e temos como bandeira a luta por um mundo sustentável. O continente latino-americano é mundialmente conhecido por suas imensas florestas, com uma rica biodiversidade, cuja preservação se deve aos povos originários que o habitam, há milhares de anos. Com eles temos muito a aprender sobre a preservação da natureza, e é disso que trata este artigo, valendo-nos de uma pesquisa bibliográfica, para verificarmos no imaginário dos povos indígenas, elementos constitutivos para uma espiritualidade ecológica integral, a única capaz de conscientizar os povos de que só sobrevivemos se a Terra vive..
NON-LYAPUNOV STABILITY OF SINGULAR SYSTEMS: CLASSICAL AND MODERN APPROACHES WITH APPLICATION TO AUTOMATIC DRUG DELIVERY

In this paper sufficient conditions for both practical and finite time stability of linear singular continuous time delay systems were introduced. The singular and singular time delay systems can be mathematically described as and , respectively. Analyzing finite time stability, the new delay independent and delay dependent conditions were derived using the approaches based on Lyapunov-like functions and their properties on the subspace of consistent initial conditions. These functions do not need to be positive on the whole state space and to have negative derivatives along the system trajectories. When the practical stability was analyzed, the approach was combined with classical Lyapunov technique to guarantee the attractivity property of the system behavior. Furthermore, an LMI approach was applied to obtain less conservative stability conditions. The proposed methodology was applied and tested on a medical robotic system. The system was designed for different insertion tasks playing important roles in automatic drug delivery, biopsy or radioactive seeds delivery. In this paper we have summarized different techniques for adequate modeling, control and stability analysis of the medical robots. The model of the robotic system, with the tasks described above, the entire system can be decomposed to the robotic subsystem and the environment subsystem. Modeling of the system by the method mentioned has been proved to be suitable when the force appears as a result of the interaction of the two subsystems. The mathematical model of the system has a singular characteristic. The singular system theory could be applied to the case described. It is well known that all mechanical systems have some delay. In that case a theory of singular systems with delayed states may be applied, as well. For the second phase in which there is no interaction, the dynamic behavior can be analyzed by the classic theory.
