Published: September 2023

Determining the main dimensions of the small vessels while designing is an important and difficult task due to the large number of mutually exclusive factors affecting the hydrodynamic characteristics of such vessels. The existing patterns for determining the length, width and draft of small vessels are quite general. This complicates their usage for the vessel of a specific design. In this case, it is necessary to check technical solutions, one of the ways that may be implied is the usage of computational fluid dynamics (CFD) methods. This paper presents the results of the numerical simulation of boat movement in the transient mode with Froude numbers up to 1.2. The process of preparation and numerical modeling of the aerodynamics of a composite wing in the NUMECA/FineMarineTM software package is described, the choice of the turbulence model and the parameters of the computational grid, including the resolution of the boundary layer, is justified. The study of the influence of three variants of the width and shape of the aft tip on the change in draft, trim angle, wetted surface and resistance of the boat is carried out. An increase in the width of the flat planing part of the aft tip has a favorable effect on the hydrodynamic characteristics of a small vessel, even when moving in transition mode at L/B from 3.5 to 3.99. At the same time, the use of the extension of the underwater part of the aft tip requires a more detailed study.

Particular attention should be paid to the possibility of completing power plants with water cannons with star-shaped engines of domestic production.
Analysis of Start-Up Share Valuation on the Indonesia Stock Exchange for the 2017-2022 Period Using the DFC GMV and Tobins'q Methods
Authors: Hartono Hartono
Published: September 2023

The phenomenon of the proliferation of startup companies in Indonesia that cannot be separated from the use of digital technology brings a fragrant aroma to venture capital investment companies. The number of startup companies that received the investment funds are bringing them to the Indonesian Stock Exchange by conducting an IPO even though the company has not been established for a long time. There is a correlation between the rapid growth of startups in Indonesia with "bubble.com" the phenomenon that occurred in Silicon Valley between the years 1999 and 2000. The surge in assets of startup companies is currently caused by stock valuation, which is based on a single valuation, without assessing assets, cash flows, or other aspects that affect the valuation value of a company. Recently, the stock price of startup companies began to fall, and is considered the same as the phenomenon "bubble.com" another indication is that there are mass layoffs of company employees; this condition also occurs in Silicon Valley. In this case, it is necessary to conduct an intrinsic assessment of startup shares empirically and in accordance with applicable valuation standards to see the condition of the company as a whole. The valuation methods used in this study are Gross Merchandise Value, Discounted Cash Flow and Tobins'q, it is expected that these three methods can represent the valuation analysis of the company so that investors know the intrinsic value of startup companies and are expected not to be Overvalued.

Authors: Yashkov Alexander V. , Polyakov Viktor A. , Shelyhmanova Marina V. , Shelyhmanova Anastasia A.
Published: September 2023

INTRODUCTION. Prolonged inactivity associated with exacerbation of a chronic disease or immobilization of the upper limb after injuries and operations leads to the development of functional disorders in the shoulder joint and the development of secondary changes, such as muscle atrophy, contractures, osteoporosis. Therefore, the early application of functional methods of treatment is pathogenetically justified, among which mechanotherapy on robotic devices occupies an important place.
AIM. To study the effectiveness of using the FLEX-F04 device in diseases and injuries of the shoulder joint.
MATERIALS AND METHODS. According to the inclusion criteria, 60 patients were under our supervision. By random sampling, all patients were divided into two groups of 30 people each. All patients underwent a clinical examination, assessed algofunctional index on the VAS scale, the degree of dysfunction in the arm, shoulder and hand according to the DASH questionnaire, electrothermometry.
RESULTS. As a result of treatment and rehabilitation measures, there was a significant increase in the angles of flexion, horizontal adduction, abduction, external and internal rotation in the shoulder joint, a decrease in pain syndrome and an increase in daily activity according to the DASH questionnaire in patients of both groups. In the main group, these indicators were significantly better than in the comparison group. The increase in thermal radiation as a result of the robotic mechanotherapy procedure averaged 0.6 0.1C.
DISCUSSION. Robotic mechanotherapy allows movement in the shoulder joint in accordance with its biomechanics, reduces the load on the musculoskeletal system and thereby prevents the appearance or strengthening of the pain component during the procedure. This contributes to an active increase in the amplitude of movements and improvement of the functional capabilities of the shoulder joint, which has a positive effect on daily activity. An increase in thermal radiation in the shoulder joint area during the procedure can serve as an indirect sign of improved microcirculation and neuro-vascular regulation.
CONCLUSION. The use of the FLEX-F04 robotic mechanotherapy device of the upper extremities according to the proposed method increases the volume of movements in the shoulder joint, reduces pain syndrome, increases blood circulation of the shoulder joint area and improves neuro-vascular regulation, increases daily household activity. Early inclusion of the device in the rehabilitation process makes it possible to shorten the duration of rehabilitation treatment and achieve a functional range of movements in the shoulder joint.

INTRODUCTION. Due to the demographic aging of the population, the problem of treatment of age-related diseases and prevention of premature aging in modern healthcare has become particularly urgent. One of the most promising approaches is the impact on the molecular mechanisms of aging, including the activation of adaptive systems and suppression of pathological processes in the body. Methods of extracorporeal hemocorrection have proved to be a good idea in this respect.
AIM. To evaluate the effectiveness and safety of hardware plasmapheresis as a technology for correcting aging biomarkers.
MATERIAL AND METHODS. A technique of therapeutic plasmapheresis use was introduced for the correction of aging biomarkers. Twenty-four participants (male and female) aged 4060 years with an elevated level of one or more aging biomarkers underwent a course of therapeutic plasmapheresis in the daytime hospital. All participants underwent four procedures of therapeutic hardware plasmapheresis once every 3 days with 30 % volume of circulating plasma followed by replacement with colloid (5 % albumin solution) and crystalloid solutions (saline solution) in a 1:3 ratio or only crystalloid solutions.
RESULTS AND DISCUSSION. A comparative evaluation of aging biomarkers before the procedure and 17 and 30 days after hardware plasmapheresis showed that therapeutic plasmapheresis affects the levels of human aging biomarkers in blood. A significant decrease in the levels of such biomarkers as homocysteine, urea, gamma-glutamyl transpeptidase, alkaline phosphatase, creatine phosphokinase, cholinesterase, and uric acid was shown. No significant differences were detected when we performed a comparative assessment of biochemical blood parameters following plasmapheresis with or without albumin replacement on biochemical blood parameters. Stable hemodynamic parameters during plasmapheresis and the absence of adverse reactions in patients confirm the safety and tolerability of the therapeutic plasmapheresis procedure.
CONCLUSION. Implementing this technique into clinical practice will allow the development of approaches to etiotropic therapy of many chronic age-related pathologies. These treatments have the potential to increase life expectancy and improve its quality.

RETURNING TO THE NEP
Authors:   International Black Sea University, Papiashvili Tatiana P.
Published: September 2023

The literature review indicated that in most cases the NEP is analyzed as a specific policy in a specific period of time in a specific country. International experience with similar reforms in Cuba, China and East Germany shows many common approaches. Using the inductive method of research (bottom-up analysis), allows us to analyze the NEP as a theory of transition from a capitalist to a socialist economy. In this article, on the example of the Georgian economy, two postulates of the NEP are considered, which are basic and common in modern economic theory: (a) the need to use economic interests, incentives, motivation to achieve any economic goal; (b) the political and economic role of a mixed economy.
NEW FINANCIAL INSTRUMENTS AND TECHNOLOGIES THAT ALLOW FOR AN ASYMMETRIC RESPONSE TO THE CHALLENGES AND THREATS TO THE RUSSIAN ECONOMY FROM THE COLLECTIVE WEST
Authors:   Plekhanov Russian University of Economics, Ryabukhin Sergei N.
Published: September 2023

The article is devoted to the threats of global chaos in global finance, the causes of these threats, possible consequences, as well as tools that can build a system of preventive measures to counteract chaos. In particular, with the help of these tools, it is possible to build both a non-monetary settlement system and create a financial system where money has an internal measure of value. This will make it possible to counteract the further development of chaos in the global financial system and create a supranational means of payment for the BRICS countries, the EAEU, the SCO and other integration unions, as well as build an investment reserve circuit with the possibility of generating long and cheap financial resources, which will help strengthen the financial sovereignty of the Russian Federation.

Mass Ratio of Single-line Spectroscopic Binaries with Visual Orbits Using Bayesian Inference and Suitable Priors*
Authors: Anguita-Aguero Jennifer , Mendez Rene A. , Videla Miguel , Costa Edgardo , Vanzi Leonardo , Castro-Morales Nicolas , Caballero-Valdes Camila
Published: September 2023

We present orbital elements for 22 single-line binaries, nine of them studied for the first time, determined from a joint spectroscopic and astrometric solution. The astrometry is based on interferometric measurements obtained with the HRCam Speckle camera on the SOAR 4.1 m telescope at Cerro Pachon, Chile, supplemented with historical data. The spectroscopic observations were secured using Echelle spectrographs (FEROS, FIDEOS, and HARPS) at La Silla, Chile. A comparison of our orbital elements and systemic velocities with previous studies, including Gaia radial velocities, shows the robustness of our estimations. By adopting suitable priors of the trigonometric parallax and spectral type of the primary component, and using a Bayesian inference methodology developed by our group, we were able to estimate mass ratios for these binaries. Combining the present results with a previous study of other single-line binaries from our team, we present a pseudo mass-to-luminosity relationship based on 23 systems (46 stars) in the mass range 0.6 ≤ M
⊙ ≤ 2.5. We find a reasonable correspondence with a fiducial mass-to-luminosity relationship. We conclude that our methodology does allow us to derive tentative mass ratios for these types of binaries.
Enhanced Size Uniformity for Near-resonant Planets
Authors: Goyal Armaan V. , Dai Fei , Wang Songhu
Published: September 2023

Super-Earths within the same close-in, compact planetary system tend to exhibit a striking degree of uniformity in their radius, mass, and orbital spacing, and this “peas-in-a-pod” phenomenon itself serves to provide one of the strongest constrains on planet formation at large. While it has been recently demonstrated from independent samples that such planetary uniformity occurs for both configurations near and distant from mean motion resonance, the question thus remains if the strength of this uniformity itself differs between near-resonant and nonresonant configurations such that the two modes may be astrophysically distinct in their evolution. We thus provide in this work a novel comparative size uniformity analysis for 48 near-resonant and 251 nonresonant multiplanet systems from the California Kepler Survey catalog, evaluating uniformity both across systems and between planetary pairs within the same system. We find that while multiplanet configurations exhibit strong peas-in-a-pod size uniformity regardless of their proximity to resonance, near-resonant configurations display enhanced intra-system size uniformity as compared to their analogous nonresonant counterparts at the level of both entire systems and subsystem planetary pairs and chains. These results are broadly consistent with a variety of formation paradigms for multiple-planet systems, such as convergent migration within a turbulent protoplanetary disk or planet–planet interactions incited by postnebular dynamical instabilities. Nevertheless, further investigation is necessary to ascertain whether the nonresonant and near-resonant planetary configurations respectively evolve via a singular process or mechanisms that are dynamically distinct.
The Division between Weak and Strong Explosions from Failed Supernovae
Authors: Coughlin Eric R
Published: September 2023

Some massive stars likely fail to produce core-collapse supernovae, but these failed supernovae (FSNe) can generate an electromagnetic outburst prior to the disappearance of the star, as the mass lost to neutrinos during the stellar core collapse results in the formation and breakout of a second shock. We show that, when the mass lost to neutrinos is sufficiently small, there are two self-similar solutions that describe the propagation of a weak shock into a hydrodynamically expanding envelope that simultaneously yield accretion onto the black hole. The larger Mach number solution is unstable and yields the minimum Mach number that a shock must have to strengthen into the energy-conserving regime. Above a critical mass loss, there are no weak-shock solutions, implying that there are only strong explosions if the neutrino mass loss is above a critical value, and this value is a few percent of the mass of the star (and is physically achievable) for typical parameters. Our results imply that the fate of the explosion from an FSN—weak with little to no mass ejection or strong with the expulsion of the majority of the envelope—is a sensitive function of the stellar properties and the neutrino mass loss. We also show that there is a second type of self-similar solution for the shock that results in the settling of the gas near the compact object, which may be applicable to nonterminal stellar eruptions and the response of a gaseous disk to gravitational-wave induced mass loss from a binary black hole merger.
Formation of Inner Planets in the Presence of a Cold Jupiter: Orbital Evolution and Relative Velocities of Planetesimals
Authors: Guo Kangrou , Kokubo Eiichiro
Published: September 2023

We investigate the orbital evolution of planetesimals in the inner disk in the presence of nebula gas and a (proto-) cold Jupiter. By varying the mass, eccentricity, and semimajor axis of the planet, we study the dependence of the relative velocities of the planetesimals on these parameters. For classic small planetesimals (1016–1020 g) whose mutual gravitational interaction is negligible, gas drag introduces a size-dependent alignment of orbits and keeps the relative velocity low for similar-sized bodies, while preventing orbital alignment for different-sized planetesimals. Regardless of the location and the mass ratio of the planetesimals, increasing the mass and eccentricity or decreasing the orbital distance of the planet always lead to higher relative velocities of the planetesimals. However, for massive planetesimals, the interplay of viscous stirring, gas damping, and secular perturbation results in the lower velocity dispersion of equal-sized planetesimals when the planet is more massive or when it is located on a closer or more eccentric orbit. The random velocities of such planetesimals remain almost unperturbed when the planet is located beyond Jupiter’s current orbit or when it is less massive or less eccentric than Jupiter. Unlike small planetesimals, such large planetesimals can grow in a runaway fashion, as in the unperturbed case. Our results imply that the presence of a cold Jupiter does not impede the formation of inner rocky planets through planetesimal accretion, provided that the planetesimals are initially large.
Radiotherapy dose de-escalation in patients with high grade non-Hodgkin lymphoma in a real-world clinical practice
Authors: Yadav Budhi Singh , Dey Treshita
Published: September 2023

Purpose: The standard treatment of non-Hodgkin lymphoma (NHL) comprises combined modality treatment, radiotherapy (RT), and chemotherapy with rituximab which has significantly improved both disease-free survival (DFS) and overall survival (OS). However, there is no uniformity in radiation dose usage in these patients. In this retrospective study, we compared lower radiation dose with higher in patients with aggressive NHL.Materials and Methods: From 2007 to 2017, treatment records of all high-grade NHL or diffuse large B-cell lymphoma and non-central nervous system NHL were included. We compared response rates, OS and DFS of patients who received ≤30 Gy RT to those with >30 Gy. Univariate and multivariate analyses were done to determine factors affecting prognosis, i.e., age, sex, stage, International Prognostic Index (IPI), adding rituximab, and radiation dose.Results: A total of 184 NHL patients treated with combined modality or radiation alone having complete follow-up details were analyzed. At median follow-up of 66.8 months, 5-year OS was 72.8% in high-dose group versus 69.9% in low-dose group (p = 0.772) and 5-year DFS 64.7% versus 64.1% (p = 0.871). Patients having early-stage disease receiving low dose and those with advanced disease treated with >30 Gy had better OS and DFS though not statistically significant. Adding rituximab was associated with significantly better OS and DFS irrespective of radiation dose delivered. High IPI score and omitting rituximab were the only factors that significantly worsened both OS and DFS. Acute radiation toxicities were comparable in both groups (p = 0.82). Among late toxicities, no patient developed a second malignancy and 5% died due to cardiovascular complications (p = 0.595) though only two patients (1.1%) had received thoracic radiation.Conclusion: The two groups had comparable response rates, acute toxicities, DFS and OS. This study suggests that RT dose reduction may be possible in high-grade NHL without compromising the DFS and OS.

BACKGROUND: According to the World Health Organization (WHO), it is predicted that hearing loss will increase to 2.5 billion people by 2050. Risk factors associated with hearing loss can occur in the uterus, at birth, or acquired.
AIM: This study aims to determine the most common risk factors and their relationship with the severity of hearing loss.
METHODS: Seven databases (NELITI, PubMed, SpringerLink, ScienceDirect, ProQuest, Emerald Insight and Wiley Online Library) were searched in January and February 2022. The keyword terms used were related to hearing assessment, hearing loss, and risk factor(s).
RESULTS: The initial search resulted in 7608 articles. A total of 1234 underwent title and abstract screening. Of these, 1223 were excluded due to various criteria. A total of 11 articles were assessed for eligibility, all of which met the inclusion criteria. In the 11 analyzed articles, the risk factors were categorized as prenatal and postnatal. The most common prenatal risk factors included genetic factor(s), family history, consanguineous marriage, and maternal infection during pregnancy. Meanwhile, the most common postnatal risk factors included prolonged mechanical ventilation, hyperbilirubinemia, asphyxia, premature birth, low birth weight, congenital anomalies, and consumption of ototoxic drugs. In one study, individuals with one risk factor had a hearing threshold of 76.47 ± 28.27 decibels (dB) nHL, whereas individuals with four risk factors had a hearing threshold of 85 ± 40.41 dB nHL.
CONCLUSION: The most common risk factors for hearing loss are genetic factor(s), prolonged use of mechanical ventilation, hyperbilirubinemia, birth defects, and consumption of ototoxic drugs. In addition, the more risk factors an individual has, the likelihood of hearing loss is greater and the degree of hearing loss is more severe.

Macrofungi are classified in the phylum Ascomycota and Basidiomycota and they are very important from an ecological and economic point of view. Most studies of fungi in Colombia have been carried out mainly in the Andean Region, especially in the Departments of Antioquia, Valle del Cauca and Cundinamarca. However, other Departments in the Andean Region, like Tolima, located in the Cordillera Central, are well documented for plants (4,797 species) and animals (2,983 species), but very poorly documented in terms of knowledge of fungal diversity.

This study provides a compiled and annotated checklist of all known macrofungi in the Department of Tolima, based on published literature and on the identification of new specimens collected from five localities of the Department. All records were updated taxonomically and we include detailed information on the localities in which they are distributed in the Department. The list includes 164 taxa distributed in 15 orders (Agaricales, Polyporales, Russulales, Boletales, Hymenochaetales, Xylariales, Auriculariales, Thelephorales, Cantharellales, Hypocreales, Pezizales, Gloeophyllales, Phallales, Tremellales, Dacrymycetales) and eighteen records in a doubtful taxa section. We present 26 new reports, 19 for Tolima and nine for Colombia. We also provide genetic and phylogenetic evidence of the occurrence of Gloeoporus telephoroides and Podoscypha venustula in Colombia. This checklist provides the basis for future studies on species diversity and taxonomy in Tolima, by identifying the least studied taxa and ecosystems and conservation priorities.
Pourquoi l’amour ?
Authors: Ben Soussan Patrick
Published: September 2023

L’auteur vous explique en quatre enjambées pourquoi il faut réhabiliter le verbe aimer en psycho-oncologie. Il ne dit pas alliance ou lien thérapeutique, attitude relationnelle ou d’écoute, sollicitude, bientraitance voire dévouement. Ni « intelligence émotionnelle dans le soin », « travail émotionnel ou relationnel du soignant », il dit « amour ».
Les Freinet et la « science » : étude d’usages polémiques de l’image de l’autodidaxie
Authors: Dupeyron Jean-François
Published: September 2023

Cet article aborde la représentation de l’autodidaxie dans plusieurs interprétations de l’itinéraire et de l’œuvre d’Élise et Célestin Freinet. Longtemps, la compréhension de cette œuvre fut partiellement biaisée par une fausse opposition entre la science universitaire et les praticiens de terrain, jugés plus ou moins autodidactes. En ce sens, l’autodidaxie était brandie par les uns comme critère dépréciatif, par les autres comme marque d’authenticité prolétarienne et de matérialisme véritable. L’article restitue ces débats et exhibe les usages et mésusages de l’image de l’autodidaxie dans certains courants alternatifs aux formes scolaires institutionnelles. Ces usages de l’image de l’autodidaxie sont presque toujours agonistiques et inscrits dans des conflits sociaux, politiques et culturels.
Introduction à la ludomusicologie : le cas de Shovel Knight
Authors: Blum Mickael
Published: September 2023

L’étude de la musique de jeu vidéo dans les milieux académiques est une discipline récente qui remonte à la charnière des années 1990 et 2000. Elle a ouvert un champ musicologique spécifique nommé « ludomusicologie », approche pluridisciplinaire dans laquelle l’histoire de la technologie et la pratique du jeu vidéo côtoient une musicologie plus classique, faite d’analyses formelles, motiviques et harmoniques. Le présent article se donne pour mission de fournir les bases nécessaires à la compréhension de cette discipline au travers de l’étude d’un cas, celui d’un jeu de plateformes en deux dimensions nommé Shovel Knight (Yacht Club Games, 2014). Ces quelques pages doivent être vues comme une entrée en matière d’un champ d’étude quasiment absent des milieux musicologiques francophones en Europe. Au départ de généralités sur la musique de jeu vidéo, les premiers morceaux de la bande originale de Shovel Knight sont abordés au moyen des outils habituels à l’analyse de la musique savante occidentale. Couplée à une approche plus spécifique de la composition musicale au moyen du programme FamiTracker, cette analyse plurielle de l’objet audiovisuel permet alors de replacer les morceaux dans leur contexte d’écoute en jeu et de comprendre comment la musique de Shovel Knight concorde avec l’esthétique du jeu, ainsi qu’avec sa narration.
Adapter l’enseignement, les institutions et les dispositifs scolaires en situation coloniale et postcoloniale
Authors: Fageol Pierre-Éric , Labrune Badiane Céline
Published: September 2023

Ce dossier rassemble des contributions sur l’adaptation des contenus de l’enseignement, des institutions d’enseignement du primaire au supérieur ainsi que des dispositifs scolaires dans les différents territoires de l’Empire colonial français. Il donne une première vue d’ensemble sur les débats et les principes de l’adaptation de l’éducation ainsi que sur les manières et formes d’adapter qui diffèrent selon les périodes et le statut du territoire. Les influences réciproques entre les différents territoires coloniaux sont au cœur d’une réflexion sur les normes et les pratiques au niveau des Empires. Les objectifs de l’adaptation de l’enseignement étant initialement soumis à ceux de la colonisation, les critiques sur sa mise en œuvre se développent progressivement au lendemain de la Seconde Guerre mondiale avant que les indépendances ne redéfinissent les contours d’un enseignement adapté aux nouveaux enjeux postcoloniaux.
L’adaptation de l’enseignement de l’histoire-géographie à l’école primaire à La Réunion au cours de la Troisième République : entre reconnaissance identitaire et acculturation nationale
Authors: Fageol Pierre-Éric
Published: September 2023

L’analyse des textes officiels et des supports pédagogiques de l’école primaire à La Réunion sous la Troisième République laisse entrevoir une évolution du processus d’acculturation nationale dans lequel la petite patrie prend une part de plus en plus prépondérante. Valorisée dès le milieu du xix e  siècle en qualité de microcosme du national, l’identité réunionnaise est ainsi reconsidérée dans les curricula et leur adaptation au milieu colonial. La redéfinition des liens entre la grande et la petite patrie, entre l’universel et le particulier, devient ainsi une revendication pleinement assumée et mise en œuvre dans les programmes d’enseignement de l’histoire et de la géographie. Les politiques et les pédagogues s’entendent pour affirmer que l’enracinement local ne peut être sacrifié sous prétexte d’une nécessaire intégration nationale. Désormais, la posture revendicative est que la culture républicaine doit être plus attentive aux singularités individuelles. Il s’agit donc d’une remise en cause de la « république coloniale » dans le sens où les spécificités culturelles locales ne sont plus perçues dans une hiérarchie d’ordre axiologique définissant uniquement l’enseignement de l’histoire et de la géographie de La Réunion par rapport au prisme métropolitain.
Entre africanisation, sénégalisation et wolofisation : l’adaptation de l’enseignement de l’histoire en AOF et au Sénégal (1903-2023)
Authors: Labrune Badiane Céline
Published: September 2023

Dès la première organisation de l’enseignement en AOF en 1903, l’objectif était de fonder une école « adaptée », par l’enseignement du milieu local et donc de l’histoire locale. L’histoire a notamment été investie d’une mission idéologique visant à démontrer les bienfaits de la colonisation française en Afrique en contraste avec un passé chaotique. La réflexion sur la décolonisation de l’histoire et son enseignement a été engagée avant les indépendances, nourrissant le combat politique. Après les indépendances, l’histoire est mobilisée et diffusée à travers le canal de l’école par les nouveaux États africains indépendants pour construire les États nations. Au Sénégal, les programmes ont été révisés à plusieurs reprises, allant vers un recentrage sur le national. Dans cet article, il s’agit de retracer le long processus de décolonisation de l’histoire scolaire, à partir du cas de l’Afrique de l’Ouest francophone et plus spécifiquement du Sénégal.
Les Officiers des Affaires Africaines au Cameroun : un corps de renseignement spécial au cœur du pouvoir colonial (1954-1960)
Authors: Noubou Noumowe Léonel
Published: September 2023

Entre 1954 et 1960, le ministère des Colonies crée un corps spécial chargé du renseignement dans les territoires français subsahariens. Appelé corps des Officiers des Affaires Africaines (OAA), l’idée est de mettre à la disposition des administrateurs coloniaux, une poignée d’officiers dont la formation les prédispose à préparer les plans de défense et à proposer des solutions pour lutter contre les contestations coloniales de plus en plus récurrentes. Entre attributions ministérielles et missions confiées sur le terrain, leur insertion dans l’appareil administratif local s’accompagne de tensions entre pouvoir civil et pouvoir militaire en situation coloniale. Mal connu et peu documenté, ce corps a pourtant joué un rôle décisif dans le renouvellement des pratiques de surveillance coloniale et le processus de décolonisation, notamment au Cameroun, mais aussi ailleurs en Afrique Occidentale Française (AOF) et en Afrique Équatoriale Française (AEF).
