A GIS-Based Spatial Decision Support System for Facility Location Planning in Nigeria
Authors: Otun Olayinka Waziri
Published: October 2023

Abstract

Public facilities are to be located optimally in the interest of society. In Nigeria, public facilities' locations are largely influenced by administrative constraints and politics, rather than efficiency and equity. This practice limits access, most especially, in rural communities where the population is dispersed.  Studies on efficiency and equity in access to public health facilities focused on urban centres. The aim of this study, therefore, is to advance the understanding of the application of the spatial decision support system (SDSS) to evaluate efficiency and equity in access to public facilities in rural regions. The study used Ogun State, Nigeria as a case.  The data used include the population and coordinates of the location of the settlements, coordinates of the location of health facilities and the transport networks. This study showed that 38.5% of settlements do not have access to primary care and the application of the p-median model showed that the efficiency of the existing location of health facilities can be improved by 40.6%.  Application of the maximal covering location model showed that the existing maximum travel distance of 26.3km can be reduced. It can be reduced for the sake of equity to 9.9 km. This study demonstrated ways to develop evaluative tools for analyzing the distribution of public facilities in Nigeria. It is suggested that planners in rural regions of other developing countries can adopt these techniques and tools to make their location decisions more logical.

The growing of X-ray imaging around the world has implication towards radiation    protection of medical field. Higher usage in radiation commonly have been seen as a simple workload issue without future challenges. Unfortunately, due to improvement in technology and techniques, it caused the amount of X-ray procedures increase which requiring medical professionals in order to ensure patient who exposed to radiation has maintain their close physical contact. As many processes are complex, risk of severe occupational exposure become higher, thus             necessary steps should be considered. It is important to ensure the lower effects of exposure are achievable. If the dosage limit for the lens of the eye is lowered in the near future, additional attention to eye protection may be required. There are many essential elements needed in ensuring                   medical field especially for X-ray imaging to be more proper and reasonably secured for example           education and training in radiation protection.

Published: October 2023

The COVID-19 pandemic and its associated restrictions made the concept of home testing increasingly popular. Here, we designed a linear transport unit connected to a paper-based multiplexed colorimetric platform, which can be used to test for food safety and physiological status. The device is composed of a linear transport unit and a paper-based multiplexed colorimetric reaction unit. The linear transporting unit uses the capillary phenomenon to collect samples, and the multiplexed colorimetric reaction unit can be used to detect different targets using a hydrophilic area and wax as the hydrophobic barrier. A rapid and multiplexed naked-eye readout of the colorimetric response is achieved in a few minutes. In this study, we demonstrate that the device can be used to detect nitrite, pesticides, lactate, and glycogen. It is a convenient and cheap home self-testing device that can be applied to different situations. This device could lead to earlier screening and, consequently, earlier referrals for further confirmation and treatment.

An Assessment of the Utilisation of IPPIS and GIFMIS as Modes of Payments in Tertiary Educational Institutions in Ogun State, Nigeria
Authors: Olabode Balikis , Adetoro Rasheed Adenrele
Published: October 2023

The study aassessed the utilisation of Integrated Payroll and Personnel Information System (IPPIS) and Government Integrated Financial Management and Information System (GIFMIS) as modes of payments in Tertiary Educational institutions in Ogun State, Nigeria with the objectives of investigating the level of awareness of end users on the new government payment policies, and also to determine the relevance of the policies, identify their problems and proffer solutions. The theoretical framework for this study was based on realistic evaluation, a form of theory-based evaluation developed by Pawson and Tilley (1997, 2006), that showcased that outcomes of policies equals mechanism plus concept. Primary data was gathered via close-ended questionnaires. Descriptive statistical tools such as frequencies, percentages in cross tabulations were utilized in analyzing the responses to the questionnaire items. Findings from the study revealed that majority of the respondents have knowledge of the meaning of IPPIS and GIFMIS, and they see the policies as a much needed change in the federal government payment system. Though for now, they delay access to overhead allocations and its utilization, workload seems repetitive and complicated, they debar research donors, make reconciliation of accounts cumbersome, discourage innovations of intellectual properties in Tertiary Educational Institutions, delay contractors payment due to weak communication signals, and seen to be used as a tool to silence unionism, among other findings.  It was concluded that contrary to majority belief and apriori expectations, introduction of these policies, though relevant (centralization of government funds) may not curb corruption in federal government financial system, but it will rather get it re-directed elsewhere unless the needful are done. It was therefore recommended that for the policies to work economically, effectively and efficiently there should be timely release of research funds for tertiary educational institutions without sabotage. Adequate monitoring and supervision for checks and balances of the Ministries/Departments/Agencies (MDAs) for effective achievement of the objectives of the new policies are paramount. Furthermore, the new policies should be administered alongside good governance which entails accountability, transparency and probity to ensure adequate and prompt payments to those entitled.
Genome and classification of viruses
Authors: Eriso Feleke
Published: October 2023

The types of classification of viruses available in literature include ICTV Classification, Holmes Classification, LHT System of Virus Classification, Casjens & Kings Classification of Virus, and Baltimore Classification of Virus. Out of the aforementioned schemes of classification Baltimore classification of viruses which classified viruses into seven groups was found to be more pragmatic than others being free from bewildering events. Baltimore classification of viruses placed mRNA in the center, and described the obligatory pathways to mRNA from DNA or RNA Genomes. It is an obligatory relationship between the viral Genome & its mRNA. The key objective of this study is to forward a pragmatically consistent and persuasive scheme for the classification of viruses where the Genome is the unit of both structure & function of every individual of viruses and of all other genomic-things.

Published: October 2023

Antecedentes: El protocolo actual de reanimación cardiopulmonar (RCP) se ha establecido integrando varios procesos que se han estudiado durante más de un siglo. Debido al éxito de estas maniobras, la comunidad médica considera que se debe preservar la circulación sanguínea durante la RCP. Métodos y resultados: se pidió a 202 médicos con experiencia en RCP que completaran una encuesta de dos partes para evaluar las declaraciones sobre la calidad de la RCP de la Asociación Americana del Corazón (AHA). Posteriormente, se les dio una revisión de los principios de fisiología y se les presentó la hipótesis de que es poco probable que la RCP genera una circulación sanguínea efectiva. Se pidió a los médicos que volvieran a evaluar sus respuestas anteriores después de la revisión de fisiología. Inicialmente, más del 70% de los médicos encuestados consideraban las compresiones torácicas capaces de distribuir sangre oxigenada por todo el cuerpo. Sin embargo, solo el 32,7% creía que esta afirmación era correcta después de reconsiderar conceptos clave sobre la fisiología circulatoria. Conclusión: Después de revisar los principios fisiológicos del sistema circulatorio, el 67% de 202 médicos con experiencia en RCP consideraron dudoso o falso que la sangre pueda circular durante las maniobras de RCP. El 51,5% de los médicos encuestados considera cierta la siguiente hipótesis sobre la RCP: durante las maniobras de reanimación cardiopulmonar actuales, es poco probable que la sangre circule por las cámaras del corazón, viaje al pulmón en busca de oxígeno y regrese al corazón para ser impulsada a otros órganos. como el cerebro. Es necesario extender la encuesta a un número más amplio de médicos para evaluar la consistencia de estos resultados y orientar futuras investigaciones sobre la hidrodinámica de la RCP.

Authors: Tun Nurhanis  , Ambareen Khan  , Mohammad Nishat Akhtar  , Sher Afghan Khan
Published: October 2023

In improving the efficiency of applications for flow over a blunt body like missiles and rockets, passive and active control is used to increase the base pressure, hence reducing the base drag. It must be mentioned that this paper covers mainly a variety of passive control methods in the form of the cavity, rib, splitter plate, spike, and some others to regulate the base pressure and drag force. Later, this paper focuses on the control of base pressure in the form of the cavity at a Mach number of 2.2 and an area ratio of 4.84. In this experiment, Computational Fluid Dynamics (CFD) is used to model a convergent-divergent nozzle and a duct. The cavity’s dimensions and locations are studied to get the optimum cavity’s control of base pressure. Two sizes of the cavity are considered which are 3:3 and 6:3. The L/D is varied from 1, 2, 4, and 6 while the Nozzle Pressure Ratio (NPR) ranges from 3 to 16. The 2-D design of a convergent-divergent axisymmetric nozzle suddenly expanded into a duct with a diameter of 22 mm with and without annular rectangular cavities is sketched using ANSYS. The results show that the base pressure is greatly influenced by the cavity’s dimension and location as well as the NPR.

Valorisation of local and low-cost eco-materials have become an imperative for the sustainable development of Concentrating Solar Power (CSP) in West Africa. In this study, the compatibility tests were carried out. These involve the application of jatropha curcas oil (JCCO) and ceramic balls, which were developed from clay coal bottom ash and sands with a focus on Burkina dune sand ceramic. The aim was to assess the applicability of using JCCO as heat transfer fluid in CSPs with direct thermocline thermal energy storage. The tests involve the use of a small container to put in contact with Jatropha oil with ceramic balls for 2160 hours and at 210 °C. From the chemical properties’ analysis, the peroxide value in the oil decreases with aging time while the acidity increase. However, the acidity remains below the limited value that is 25 mg KOH.g-1. Therefore, thermal properties that drive heat transfer and rheological properties (density, thermal conductivity, kinematic viscosity and so on) were not adjusted significantly at the storage temperature (of about 210°C). Thermal stability temperature decreased to 261.93°C for the oil aged alone as against 263.41 °C for the one that was put in contact with filler material. In the nutshell, there is no incompatibility between JCCO, and the new thermal energy storage material (TESM) developed. These couple of materials could be suitable for thermocline energy storage in CSP plant and for other applications like there use in solar cooker box.
Investigation of Sloshing in Different Tank Shapes using Smoothed Particle Hydrodynamics
Authors: Andi Trimulyono  , Suci Utami  , Deddy Chrismianto  , Parlindungan Manik
Published: October 2023

Sloshing is the violent motion of a resonant fluid in a moving tank; when the fluid moves and interacts with the tank, the dynamic pressure from such an interaction can cause large fluid deformations with tank walls. In this study, a 3D numerical simulation of sloshing was carried out with five variations of the tank model, i.e., prismatic, rectangular, tube, spherical, and the new model tank with a filling ratio of 25% and 50%. Forced oscillation motion in a roll used frequencies 1.04 Hz and 1.34 Hz. The amplitude of movement was 8.66°. One pressure sensor was used to measure dynamic pressure in the mid of the tank. Because sloshing deals with large deformation and discontinuities, the particle method was suitable for the application. This study used smoothed particle hydrodynamics based on weakly compressible SPH (WCSPH). SPH is a Lagrangian meshless method known as mesh-free computational fluid dynamics. Open-source SPH solver version 5.0 was used to reproduce sloshing in different tank shapes; in addition, advanced visualization was performed using the VisualSPHysics add-on in Blender version 2.92. The sloshing visualization is more realistic and attractive than conventional SPH post-processing. The results of this study indicate that different tank shapes influence reducing the value of dynamic pressure and hydrodynamic force. It is found that a practical tank shape is a tube tank and a new model tank with a reduced dynamic pressure value of 9% and 11% and a reduced hydrodynamic force value of 36% and 48%.

Published: October 2023

In this paper, magnetohydrodynamic laminar forced convection of nanoliquid in a rectangular channel with an extended surface, top moving wall and three cylindrical blocks is numerically studied. The Lattice Boltzmann method is used for the resolution of the governing equations. Validity of the numerical home elaborated FORTRAN code was made and good agreement was found with published results. It is interspersed in this work by the effects of the following parameters: Reynolds number (50≤Re≤200), Hartmann number (0≤Ha≤50), nanoparticles volume fraction (0≤φ≤4%) and Eckert number (0.25≤Ec≤1). The numerical solution shows that the local and average Nusselt numbers ameliorate when the value of Reynolds number, Eckert number, and the nanoparticles volume fraction are enhanced. But decreases when the Hartmann number is increased. The impacts of viscous dissipation on heat transfer rate and entropy generation are more noticeable in the presence of a magnetic field. The addition of 4% of nanoparticles enhances the local Nusselt number by about 7%.

Published: October 2023

Proteases are widely utilized both in physiological and commercial fields such as medicine, food, detergent, and leather. Plant-originated proteases play a significant role in several biomedical fields due to their easy accessibility and activity. Pakistan is an agro-based country and can be an ideal place for the isolation of industrially important proteases from plant sources such as cotton, which is the main crop and frequently available and low cost. Purification of protease was carried out by fractionation with two-fold acetone, ethanol, methanol and various concentrations (40-80%) of ammonium sulphate. The precipitates formed were collected after centrifugation and dialyzed for 24 hours against universal buffer pH 7.0 and was centrifuged in a cooled refrigerated. The dialyzed sample was loaded on Sephadex G–100 gel column. The fractions of the samples were collected and their absorbance of protein was monitored at 280 nm. The homogeneity of the purified enzyme was checked by SDS gel electrophoresis The purified protease enzyme has optimum activity at 30°C and pH 8.0 when casein was used as substrate. The Km and Vmax values of purified cotton seed's alkaline protease activity was recorded as 0.03M and 17 μmol/minute respectively. Protease activity was increased by the addition of cysteine but inhibited by Iodoacetic acid and β-Mercaptoethanol and decreased with some metal ions. These characteristics of the purified enzyme allowed classifying it as a cysteine protease. In conclusion, this study suggests that the alkaline protease enzyme is the best choice for commercial use

Published: October 2023

The causes of schizophrenia remain obscure and complex to identify. Alterations in dopaminergic and serotonergic neurotransmission are, to date, the primary pharmacological targets in treatment. Underlying abnormalities in neural networks have been identified as cell adhesion molecules (CAMs) involved in synaptic remodeling and interplay between neurons-neurons and neurons-glial cells. Among the CAMs, several families have been identified, such as integrins, selectins, cadherins, immunoglobulins, nectins, and the neuroligin-neurexin complex. In this paper, cell adhesion molecules involved in the pathogenesis of schizophrenia will be described.

Published: October 2023

We report the case of a 47-year-old man who was admitted to our clinic with an intractable headache, nausea, and sporadic vomiting, as well as speech difficulties and a ‘floating’ sensation. This man had no prior medical history. MRI of the brain showed evidence of over 20 supra- and infratentorial capsulated ring-enhancing lesions. All other paraclinical investigations done in our clinic were unremarkable and we excluded our first assumption of neurocysticercosis, as well as other parasitic infections. The patient was then referred to the Oral and Maxillofacial Surgery Clinic for an excisional biopsy of a submandibular formation, which was later verified to represent a lymph node metastasis from a poorly differentiated adenocarcinoma. A chest X-ray failed to demonstrate any significant pathology and the immunohistochemical constellation of the lymph node metastasis excluded the possibility of the primary tumor originating in the lung or the prostate. Due to the unresolved diagnostic query, a whole-body PET/CT was performed demonstrating a formation with malignant characteristics in the basal segment of the left lung, reaching the pleura and the left hilum, as well as solitary enlarged mesenteric and mediastinal lymph nodes. Following clinical consultations, it was determined that the patient was inoperable and chemotherapy and palliative CNS irradiation were recommended.

Published: October 2023

Aim: Nanopropolis has become the subject of interest in medicine and dentistry as a natural product due to its outstanding properties, particularly antimicrobial activity. This study aimed at investigating the effect of nanopropolis on flexural strength of polymethyl methacrylate (PMMA).

Materials and methods: Three groups of two acrylic resin brands namely Acropars and Triplex containing 0 (control group), 0.5%, and 1% of nanopropolis were prepared in 64×10.0×3.3 mm according to ISO 20795-2 (2013). Fifteen samples were allocated to each concentration. Flexural strength was determined following immersion in water and incubation at 37°C for 50±2 hours using a universal testing machine at a crosshead speed of 5±1 mm/min. Data were analyzed using ANOVA, Tukey HSD, and t-test. P<0.05 was set as statistical significance.

Results: Control groups of Acropars and Triplex showed the highest mean flexural strength within their own group which both were higher than the recommended 50 MPa. The mean flexural strength of Triplex incorporated with 0.5 and 1% of nanopropolis was higher than that of Acropars with the same percentage.

Conclusions: The mean flexural strength of Triplex remained above the recommended value of 50 MPa after incorporation of both 0.5 and 1% nanopropolis. However, that of Acropars dropped below it.

Congenital malformations of the biliary tract represent a relatively rare entity with which surgeons, radiologists and clinicians are not adequately familiarized. We present a rare case of gallbladder duplication in a 40-year-old female, with the accessory cystic duct entering the left hepatic duct, which depicts the fifth reported case in the international bibliography. Our case illustrates the importance of detailed knowledge of anatomical malformations of the biliary tree, serving the purpose of a preoperative diagnosis of symptomatic cholelithiasis. It is also of paramount importance to take under consideration biliary tract malformations to avoid inadvertent complications such as biliary duct injuries in case of laparoscopic cholecystectomy.

Published: October 2023

Complications following lateral retroperitoneal transpsoas lumbar fusion (LLIF) surgery include femoral nerve apraxia, bowel/bladder injury, ureteral injury, and potentially, as illustrated in this case report, Guillain-Barré syndrome. Guillain-Barré syndrome (GBS) is an autoimmune inflammatory condition that typically presents after infection, or, less frequently, post-operatively. We report a case of GBS following elective lumbar fusion through the lateral retroperitoneal transpsoas approach (LLIF). A 56-year-old patient presented with left lower extremity (LLE) weakness on post-operative day 12. EMG showed bilateral upper extremity muscle recruitment, worse distally. Following a treatment with intravenous immunoglobulin (IVIG), the patient gradually improved, and her condition was favorable at 6-month post-operative follow-up. CSF analysis and EMG should be part of the workup for patients presenting with lower extremity neuropathy following LLIF.

Introduction: Pleural cavity drainage is a crucial component of the surgical management of patients with various chest diseases. Digital drainage systems are increasingly used in contemporary thoracic surgical procedure, which is likely a result of their effectiveness in achieving early postoperative ambulation, cutting down on hospital stays and lowering costs. The vast majority of thoracic surgeons worldwide prefer digital drainage systems to traditional ones. The advantages of the former, however, are disputed by some researchers.

Aim: The objective of this study was to compare the two types of pleural drainage mechanisms, conventional and digital, in terms of duration of pleural drainage in days, financial cost, and postoperative air leak duration.

Materials and methods: The study focused on 80 patients who underwent various thoracic surgical interventions in the Clinic of Thoracic and Abdominal Surgery at St George University Hospital in Plovdiv. They were divided into two groups: group 1 consisted of 42 patients who were postoperatively attached to a conventional non-mobile pleural drainage system, and group 2 consisted of 38 patients in whom a mobile digital pleural drainage system was used. The main analyzed data were duration of pleural drainage, duration of postoperative air leak, hospital stay, and financial costs.

Results: The average duration of pleural drainage, regardless of surgery and type of drainage system applied was 4.86±0.8 days. The average duration of pleural drainage in patients attached to the mobile digital drainage system was shorter than that in patients with a conventional pleural non-mobile drainage system, regardless of the type of surgery done. This difference was statistically significant in favor of the digital pleural drainage system. The study also found a statistically significant difference in terms of financial costs in favor of digital draining system. The average cost of a hospital stay for patients attached to a mobile digital drainage system was BGN 119.40±7.15, whereas the average cost of a hospital stay for patients connected to a traditional pleural drainage system (PDS) was BGN 159±10.50. Regarding the duration of postoperative air leak, the difference between the types of pleural drainage mechanism used was not convincing.

Conclusions: Digital pleural drainage systems provide clinicians with an opportunity to assess the postoperative air leak more precisely, track its dynamics, shorten hospital stays, reduce postoperative costs, and optimize the time to remove the chest drain. Based on these features, they will undoubtedly continue to enter everyday surgical practice.
Danser dans un stade. Les chorégraphes aux Jeux de Berlin (1936)
Authors: Guilbert Laure , Gauthier Céline , Conquet Angela
Published: October 2023

Historienne de la danse, Laure Guilbert explore le pouvoir ambigu des célébrations chorégraphiques durant les Jeux Olympiques de 1936. Dans l’espace vertigineux des stades, les artistes ont composé des danses chorales qui rassemblent des milliers de participants. Si ces œuvres cristallisent les techniques rythmiques et l’idéal esthétique de l’Ausdrucktanz, elles font aussi implacablement écho à la doctrine corporelle du régime fasciste.
Le jeu : un savoir-faire d’interprétation
Authors: Le Borgne Simon , Gauthier Céline , Conquet Angela
Published: October 2023

Simon Le Borgne est danseur du Ballet de l’Opéra de Paris. Depuis 2017, il est le fil conducteur de la pièce Play d’Alexander Ekman. Alors que la scène se charge d’une atmosphère enfantine et ludique, il évoque la diversité de son travail d’interprète : qu’il s’agisse de feindre la spontanéité ou de se laisser surprendre par les consignes du chorégraphe, il improvise sans cesse pour révéler le jeu du danseur.
Une heuristique du regard. Pour des sciences sociales par l’image. Entretien avec Daniel Vander Gucht
Authors: Martens David , Vander Gucht Daniel
Published: October 2023

Alors que les sciences exactes ont le microscope, les sciences sociales pourraient-elles compter sur l’appareil photo et la caméra ? En 2017, Daniel Vander Gucht publie aux Impressions Nouvelles Ce que regarder veut dire 1 . Derrière ce titre en forme de décalque bourdieusien, l’auteur entreprend non pas un tournant visuel de la sociologie, mais bien plutôt d’analyser et de formaliser les pratiques relatives à l’usage des images dans les recherches en sociologie : au-delà de l’analyse des images, il promeut une sociologie en images et par les images, sur laquelle il revient dans l’entretien qui suit.
Des relations étudiants-institution sur WeChat . Étude de publications lors d’une cérémonie de remise de diplômes en Chine
Authors: Rocher Jean-Maurice
Published: October 2023

Cet article 1 questionne les pratiques d’étudiants chinois utilisateurs du réseau socionumérique Moments de WeChat , en regard de leur appartenance à une institution universitaire, et plus particulièrement de leur participation à la cérémonie de remise de diplôme 2020 organisée par celle-ci. Il s’agit de saisir comment les relations entre l’administration universitaire et les étudiants se perpétuent à travers les pratiques éditoriales en ligne de ces deux catégories d’acteurs interdépendants en présence, et quels sont leurs intérêts propres à activer le « dispositif communicationnel » au centre duquel figure WeChat . Le recours à l’analyse qualitative et comparative des messages publiés sur Moments par les étudiants et des articles diffusés par l’université fait entre autres apparaître un « jeu », plutôt qu’une tension, entre l’institué et l’instituant.
Quelles sublimations ? Quels équilibres ?
Authors: Danon-Boileau Laurent
Published: October 2023

On oppose sublimation « d’exception », productrice de biens culturels (quelle qu’en soit la qualité), et sublimation ordinaire, sans production particulière, mais préservant le plaisir du sujet dans la vie quotidienne. Si la première peut avoir partie liée avec l’excès économique et la pulsion de mort, la seconde se place d’emblée sous l’égide du principe de plaisir. Toutefois l’articulation de ces deux formes de sublimation, pourtant décisive, s’avère souvent délicate. Certains créateurs ont recours au clivage fonctionnel, maintenant leur conviction de toute-puissance dans le registre de la sublimation d’exception et du travail de l’œuvre, mais limitant ses effets dans le registre du quotidien et de la sublimation ordinaire. Pourtant, cette « solution » ne permet pas la prise en compte de la castration. Shakespeare le montre quand, à la fin de La tempête, Prospero l’alchimiste sacrifie son savoir civilisateur sur l’autel de la transmission, relançant alors son appétence sublimatoire.
La tentation psychobiographique. Autour des archives de Marie Bonaparte
Authors: Amouroux Rémy
Published: October 2023

La récente publication de la volumineuse correspondance entre Sigmund Freud et Marie Bonaparte a mis en lumière l’importance des archives de cette dernière. De Paris à Washington, en passant par le Texas, ce sont des dizaines de mètres linéaires qui sont aujourd’hui disponibles. Il ne s’agit pas seulement de textes techniques liés à sa production scientifique, mais aussi et surtout, de documents biographiques : lettres, journaux intimes et productions enfantines. Cette pionnière française de la psychanalyse et adepte convaincue de l’approche psychobiographique nous a en effet légué tout le matériel nécessaire pour que l’on se penche sur sa vie psychique intime. Malgré tout l’intérêt de cette démarche, cet article invite à ne pas céder trop rapidement à cette tentation psychobiographique, et à considérer ses archives comme un construit plutôt que comme un témoignage brut.
Thésée, sa vie nouvelle , ou comment vivre avec ses morts sans en mourir
Authors: Selz Monique
Published: October 2023

Thésée, sa vie nouvelle est un livre de Camille de Toledo, remarquable par son écriture, qui est une véritable création poétique qui raconte le devenir de Thésée, à la suite du suicide de son frère Jérôme et de la mort de ses parents. Tentant d’échapper à un destin de mort, Thésée s’éloigne du lieu où a vécu et péri sa famille, et part s’installer à Berlin. Mais là-bas, il s’effondre, ou plutôt, son corps s’effondre, pris de douleurs intolérables qui l’immobilisent sur son lit. Toute médication classique n’étant d’aucune efficacité, il se plonge dans les cartons d’archives qu’il avait emportés avec lui lors de sa fuite. Il y découvre alors l’histoire de ses ancêtres, caractérisée par un exil, des morts et surtout un oubli radical des valeurs d’origine. Mais cette histoire, non dite et non transmise, agit sur les deux frères, Jérôme et Thésée, à leur insu. L’auteure de cet article a vu dans cette œuvre la métaphore d’un parcours analytique et la façon dont les corps viennent révéler ce qui n’a pu s’élaborer psychiquement.
Job stressors and health of SME directors
Authors: Parmentier Clément , Truchot Didier , Lheureux Florent
Published: October 2023

Peu d’études explorent les facteurs de stress et la santé au travail des dirigeants de petites et moyennes entreprises (PME), notamment dans le contexte français. La présente étude vise à identifier les stresseurs professionnels des dirigeants de PME françaises (dirigeants propriétaires et dirigeants salariés). Elle compare également les stresseurs observés en contexte français avec ceux identifiés dans la littérature internationale. Enfin, elle évalue l’impact réel des stresseurs sur l’épuisement émotionnel, la satisfaction au travail et les troubles du sommeil. Basée sur une méthode mixte, une étude qualitative par entretiens a d’abord été menée auprès de 14 dirigeants français de PME puis une étude quantitative par questionnaire auprès de 881 dirigeants français de PME (répartis en dirigeants propriétaires et salariés). Enfin, plusieurs analyses ont été menées notamment des analyses factorielles exploratoires et confirmatoires. L’étude qualitative a abouti à une liste de 36 principaux stresseurs présentés sous la forme d’items. Les analyses factorielles ont permis d’identifier quatre facteurs de stress : les ressources humaines et les problèmes de gestion, les facteurs de stress économiques et éthiques, les facteurs de stress relationnels liés aux clients et la pression du temps. Ces facteurs de stress étaient significativement associés aux trois résultats. Bien que partageant les mêmes quatre types de facteurs de stress, des différences existent entre les directeurs propriétaires et les directeurs salariés. Cette étude contribue aux connaissances et fournit des informations utiles pour les interventions pratiques des professionnels de santé (par exemple, meilleur ajustement des actions de prévention, baromètre social) et en tant qu’outil d’auto-évaluation pour les dirigeants de PME.
