Published: November 2024

Objetivo: compreender as implicações dos operadores na rede social de puérperas no contexto do HIV. Método: abordagem qualitativa, fundamentada no referencial teórico e metodológico de Lia Sanicola. As participantes foram seis mulheres, selecionadas em serviço de referência, em um município no sul do Brasil. Técnica da entrevista semiestruturada para a construção do mapa social. Resultados: na rede primária, o companheiro foi o ajudante natural e o principal apoio para realização do seu tratamento e isso determina um efeito protetor para os cuidados à saúde. Na rede secundária, as profissionais da saúde oferecem suporte de forma isolada e fragmentada. E, quando tem ruptura nas relações sociais por conta do preconceito, da discriminação e da potencialização do isolamento social pela pandemia, ocorre a vulnerabilização da puérpera. Conclusão: a invisibilidade de operadores sociais na rede secundária dessas puérperas implica na cristalização de um modelo de serviço padronizado, indicando necessidade de mudanças, de uma prática isolada dos profissionais e equipes de saúde com intervenções em rede para a resolutividade das demandas de suas usuárias.

Objetivo: analisar a estrutura e o conteúdo das representações sociais de alunos de uma escola da rede pública de ensino a respeito da violência no âmbito escolar. Método: estudo qualitativo, ancorado na Teoria das Representações Sociais e Teoria do Núcleo Central. A produção dos dados aconteceu em maio e junho de 2022 mediante a técnica de associação livre de palavras, cujas evocações livres foram analisadas e processadas pelo Software Ensemble de Programmes Permettant L’analyse des Êvocations – EVOC, versão 2005. Resultados: participaram do estudo 54 adolescentes escolares matriculados no Ensino Médio de uma escola pública, que associaram palavras mediante o uso de termos indutores, tendo como núcleo central para o termo violência o elemento violência física; para violência escolar o elemento bullying; e sobre a violência no processo ensino e aprendizagem não houve figuração de nenhum elemento central. A zona periférica foi composta pelos elementos: violência verbal, abuso, dor, zombaria, intrigas, abandono escolar, desinteresse e abalo psicológico, respectivamente. Considerações finais: as possíveis representações reforçaram a necessidade de inserir a temática violência e bullying de forma mais ampla nas discussões de planejamento escolar, como forma de reconhecer sua importância e promover seu combate e prevenção.

Objetivo: analisar os fatores associados àadesão ao seguimento clínico e laboratorial de gestantes com sífilis. Método: estudo analítico, realizado em Unidades Básicas de Saúde, com 73 gestantes com sífilis, de maio de 2019 a maio de 2020, em um capital do Nordeste brasileiro. Coleta de dados ocorreu em três etapas: (1) levantamento dos casos de gestantes com sífilis, (2) aplicação de um formulário durante o pré-natal, elaborado pelos pesquisadores,para coleta das variáveis sociodemográficas, comportamentais e clínicas, e, (3) após o parto, coleta de dados referente ao desfecho final da gestação. A pesquisa utilizou a análise descritiva e a regressão logística, todos os testes com p< 0,05. Resultados: adesão ao seguimento clínico e laboratorial ocorreu em 25 (34,3%) gestantes; e seguem a associação com as variáveis: ter companheiro afetivo (p=0,012), sífilis no primeiro trimestre de gestação (p=0,041), início do tratamento no momento do diagnóstico (p=0,023) e pré-natal realizado por dois profissionais, médico(a) e enfermeiro(a) (p=0,039). Conclusão: a adesão foi considerada baixa. A análise multivariada aponta que ter companheiro e tratamento imediato podem indicar redução da perda do seguimento. A atenção primária tem papel fundamental no acompanhamento de gestantes com sífilis; identificar as barreiras relacionadas à adesão ao seguimento pode contribuir para a elaboração de estratégias mais direcionadas e específicas.

Authors: Indrajith D. S. , Ambegoda A. M. L. C. , Abeygunasekera A. M. , Thevarajah S. , Sosai C. S. P.
Published: November 2024

A 74-years old man with haematuria was found to have a bladder mass and left lower ureteric obstruction. The CT urogram showed lower ureteric calcification bilaterally. The endoscopic resection of the bladder mass showed amyloidosis. Resection of the stenosed left ureter with Boari flap reconstruction produced good results. Histopathology confirmed the presence of ureteric wall calcium deposits. Bilateral ureteric amyloidosis and calcification is rare. However, it is usually localized and has a good outcome. A high degree of suspicion will prompt early diagnosis which will prevent more extensive resection surgery.

Authors: Kim Jin Hwa , Lee Junyeop , Han Kyungdo , Kim Jae-Taek , Kwon Hyuk-Sang ,   on Behalf of the Diabetic Vascular Disease Research Group of the Korean Diabetes Association
Published: November 2024

Background: This study aimed to provide updated insights into the incidence and management of cardiovascular disease (CVD) in Korean adults with diabetes.Methods: Using data from the Korean National Health Insurance Service and Korea National Health and Nutrition Examination Survey, we analyzed the representative national estimates of CVD in adults with diabetes.Results: The age- and sex-standardized incidence rate of ischemic heart disease (IHD), ischemic stroke, and peripheral artery disease (PAD) decreased from 2010 to 2019 in individuals with type 2 diabetes mellitus (T2DM). However, an increase in the incidence of heart failure (HF) was observed during the same period. Only 4.96% of adults with diabetes and CVD achieved optimal control of all three risk factors (glycemic levels, blood pressure, and lipid control). Additionally, high-intensity statin treatment rates were 8.84% and 9.15% in individuals with IHD and ischemic stroke, respectively. Treatment with a sodium-glucose cotransporter-2 inhibitor (SGLT2i) or a glucagon-like peptide-1 receptor agonist (GLP-1RA) was relatively low in 2019, with only 11.87%, 7.10%, and 11.05% of individuals with IHD, ischemic stroke, and HF, respectively, receiving SGLT2i treatment. Furthermore, only 1.08%, 0.79%, and 1.06% of patients with IHD, ischemic stroke, and HF, respectively, were treated with GLP-1RA.Conclusion: The incidence of most CVD (IHD, ischemic stroke, and PAD) decreased between 2010 and 2019, whereas the incidence of HF increased. The overall use of high-intensity statins, SGLT2i, and GLP-1RA remained low among individuals with T2DM and CVD.

To explore the relation between cognitive self-regulation (CSR), social functioning, and psychopathology in schizophrenia.

Participants and Methods:

About 100 patients diagnosed with schizophrenia according to ICD-10 were taken from the Department of Psychiatry of two Post-Graduate hospitals in Kolkata, India. Positive and Negative Syndrome Scale for Schizophrenia (PANSS), Schizophrenia Research Foundation India-Social Functioning Index (SCARF-SFI), and a specially designed questionnaire on CSR were administered.

Results:

Results revealed that all the four subtests namely self-concern, occupational role, social role, and family role of the social functioning and symptoms scale of PANSS were significantly correlated with CSR.

Conclusion:

CSR was found to be a highly reliable and valid tool and was able to predict social functioning along with positive and negative symptoms.
A mixed methods study on non-adherence to oral antidiabetic agents in type 2 diabetes mellitus patients: Unveiling the post-intervention outcomes
Authors: Kumar Mukesh , Kovvuru Surendra Reddy , Bedi Gurkaran , Akhtar Naushad , Paul Pritama , Paul Uttam Kumar
Published: November 2024

Background:

Type 2 diabetes mellitus (DM) is a chronic metabolic disease. Despite available treatments, non-adherence to prescribed regimens remains a significant challenge, influenced by various factors.

Objective:

This study aims to investigate the effectiveness of interventions targeting adherence to oral hypoglycemic agents (OHAs) in T2DM management while understanding the factors contributing to treatment failure and exploring strategies to improve medication adherence and overall disease management.

Materials and Methods:

A mixed research design, integrating qualitative and quantitative methods, was applied in this study. In-depth interviews and focus group discussions were conducted among 327 patients with T2DM attending the medicine department of a tertiary medical college in Bihar for 3 years. Participants were individuals (>18 years) taking OHAs but experiencing symptoms despite treatment. Various intervention techniques were applied. Data analysis involved qualitative coding and categorization of interview transcripts.

Results:

The study revealed significant insights into the demographic profile of patients with T2DM, with notable patterns in age, gender, educational status, and employment. Forgetfulness, economic concerns, fear of adverse effects, complexity of treatment plans, non-availability of medication, and preference for alternative treatments emerged as primary barriers to adherence. Interventions led to improved adherence and diabetes management for the majority of patients, with 203 (62%) showing signs of improvement post-intervention.

Conclusion:

This study highlights the significance of understanding and addressing barriers to adherence in T2DM management. Despite limitations, the insights gained offer valuable directions for future research and interventions aimed at enhancing adherence and patient outcomes in T2DM treatment.

Authors: Emami Elahe , Shemshadi Sara , Farrashi Melody
Published: November 2024

A 72-year-old man presenting with progressive dyspnea was evaluated. Transthoracic and consequently transesophageal echocardiography verified severe mitral regurgitation (MR) caused by hypoplasia of the posterior mitral leaflet (PML) and flail of A2 scallop. A review of reported cases reveals that PML hypoplasia is an uncommon diagnosis among the adult population which can be tolerated relatively well and carries a good prognosis. Our patient had a unique course of the disease. Previously presenting with a bicuspid aortic valve and a nonsignificant MR in spite of the severely hypoplastic PML. Eventually, he became symptomatic years later as severe MR developed due to chordal rupture and flail of the anterior mitral leaflet.

Anomalous Origin of Right Coronary Artery from Left Sinus of Valsalva, Still a Therapeutic Dilemma: A Case Presentation and Brief Review
Authors: Eftekhari Seyed Shahin , Givtaj Nader , Pouraliakbar Hamidreza , Sadeghipour Parham , Maadani Mohsen , Bashghareh Peyman
Published: November 2024

An anomalous aortic origin of coronary artery (AAOCA) is a rare congenital anomaly which reported in 0.1% to 1% of the population in the literature. The most common subtype is anomalous aortic origin of right coronary artery (AAORCA) deriving from the left side. In the present case report, the therapeutic approach of AAORCA and the ongoing clinical dilemma will be discussed. A 52-year-old man was admitted with prolonged exertional chest pain and increased troponin I without any changes in electrocardiogram. After percutaneous catheterization, it revealed an ectasia in all left system coronary arteries and we suspected AAORCA. Hence, a coronary computed tomography angiography confirmed that the right coronary artery originated from the left sinus of Valsalva with a malignant interarterial course and a significant lesion at the ostium of left anterior descending. Hence, a coronary artery bypass grafting (CABG) with reimplantation of the orifice of AAORCA to the right coronary cusp was performed as a therapeutic approach. In the 12-month follow-up, the symptoms were ameliorated and there were no complications. As recommended in the American College of Cardiology/American Heart Association guidelines, patients with AAORCA should be divided into asymptomatic and symptomatic (ischemic symptoms. The patients with AAOCA who are symptomatic such as chest pain due to ischemia, ventricular arrhythmia with syncope, or aborted sudden cardiac death should have offered surgical management including unroofing, CABG, or reimplantation approaches. However, in accompaniment of AAORCA and other coronary artery disease, both CABG and translocation of AAORCA with reimplantation into a suitable origin maybe an appropriate surgical strategy with an acceptable mid-term follow-up as represented in our case.
Effectiveness of Resting Transthoracic Echocardiography at Detecting Significant Coronary Artery Disease in Adults
Authors: Woods Michael D. , Hatfield Jess , Hammonds Kendall , Pham Alex , Exaire Jose , Mixon Timothy , Nguyen Vinh , Chiles Christopher , Widmer Robert J.
Published: November 2024

Background:

Detection of the regional wall motion abnormalities (RWMA) on the transthoracic echocardiography (TTE) is commonly used to correlate with coronary artery disease (CAD) and often prompts a further workup, including cardiac computed tomography or cardiac catheterization. However, the RWMA do not consistently predict obstructive CAD. This study investigates the accuracy and reliability of the presence of the RWMA on the TTE at detecting significant CAD (≥70% vessel stenosis).

Materials and Methods:

A retrospective chart review was conducted on the adults seen by the Baylor Scott and White Temple Echocardiography Laboratory who received a resting TTE followed by a cardiac catheterization within 30 days over 4 years. The exclusion criteria included catheterization without coronary angiography and a prior history of CAD, percutaneous coronary intervention, or coronary artery bypass graft. We analyzed the RWMA on the TTE and atherosclerotic CAD on the cardiac catheterization to assess correlation.

Results:

Four hundred and thirty-five patients were included in the study, and 198 patients received ultrasound-enhancing agent (UEA). The sensitivity and specificity of the RWMA on the TTE for detecting CAD in the adults were 49.5% and 78.8%, respectively. The positive and negative likelihood ratios were 2.33 and 0.641, respectively. The use of UEA made no significant difference in the sensitivity or specificity.

Discussion:

Our results show that the presence of the RWMA on the TTE has a high ability to rule in CAD, but the absence of the RWMA displays a much lower ability to rule out CAD than previously reported. Our results also show UEA did not enhance or detract from the sensitivity or specificity of TTE on CAD. The clinicians should be aware that the presence of the RWMA on the resting TTE has a high association with obstructive CAD, but the absence of the RWMA does not sufficiently exclude CAD.

We present a new proof of the compactness of bilinear paraproducts with CMO symbols. By drawing an analogy to compact linear operators, we first explore further properties of compact bilinear operators on Banach spaces and present examples. We then prove compactness of bilinear paraproducts with CMO symbols by combining one of the properties of compact bilinear operators thus obtained with vanishing Carleson measure estimates and interpolation of bilinear compactness.
Platelet counts to spleen diameter ratio: A promising noninvasive tool for predicting esophageal varices in cirrhosis patients
Authors: Mossie Getnet Yigzaw , Nur Abdulsemed Mohammed , Ayalew Zekarias Seifu , Azibte Gebeyehu Tessema , Berhane Kaleb Assefa
Published: November 2024

BACKGROUND

Liver cirrhosis is the end stage of progressive liver fibrosis as a consequence of chronic liver inflammation, wherein the standard hepatic architecture is replaced by regenerative hepatic nodules, which eventually lead to liver failure. Cirrhosis without any symptoms is referred to as compensated cirrhosis. Complications such as ascites, variceal bleeding, and hepatic encephalopathy indicate the onset of decompensated cirrhosis. Gastroesophageal varices are the hallmark of clinically significant portal hypertension.

AIM

To determine the accuracy of the platelet count-to-spleen diameter (PC/SD) ratio to evaluate esophageal varices (EV) in patients with cirrhosis.

METHODS

This retrospective observational study was conducted at Tikur Anbessa Specialized Hospital and Adera Medical Center from January 1, 2019, to December 30, 2023. Data were collected via chart review and direct patient interviews using structured questionnaires. The data were exported to the SPSS software version 26 for analysis and clearance. A receiver operating characteristic curve was plotted for splenic diameter, platelet count, and PC/SD ratio to obtain sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, and negative likelihood ratio.

RESULTS

Of the 140 participants, 67% were men. Hepatitis B (38%) was the most common cause of cirrhosis, followed by cryptogenic cirrhosis (28%) and hepatitis C (16%). Approximately 83.6% of the participants had endoscopic evidence of EV, whereas 51.1% had gastric varices. Decompensated cirrhosis and PC were associated with the presence of EV with adjusted odds ratios of 12.63 (95%CI: 3.16-67.58, P = 0.001) and 0.14 (95%CI: 0.037-0.52, P = 0.004), respectively. A PC/SD ratio < 1119 had a sensitivity of 86.32% and specificity of 70% with area under the curve of 0.835 (95%CI: 0.736-0.934, P < 0.001).

CONCLUSION

A PC/SD ratio < 1119 predicts EV in patients with cirrhosis. It is a valuable, noninvasive tool for EV risk assessment in resource-limited settings.
Suppression of hepatic steatosis in non-alcoholic steatohepatitis model by modified Xiaoyao San formula: Evidence, mechanisms and perspective
Authors: Eid Nabil , Bhatnagar Payal , Chan Li-Li , Garcia-Macia Marina
Published: November 2024

In this letter, we comment on a recent publication by Mei et al , in the World Journal of Hepatology , investigating the hepatoprotective effects of the modified Xiaoyao San (MXS) formula in a male rat model of non-alcoholic steatohepatitis (NASH). The authors found that MXS treatment mitigated hepatic steatosis and inflammation in the NASH model, as evidenced by the reduction in lipid droplets (LDs), fibrosis markers and lipogenic factors. Interestingly, these hepatoprotective effects were associated with androgen upregulation (based on metabolomics analysis of male steroid hormone metabolites), adenosine 5’-monophosphate-activated protein kinase (AMPK) activation, and restoration of phosphatase and tensin homolog (PTEN) expression. However, the authors did not clearly discuss the relationships between MXS-induced hepatic steatosis reduction in the NASH model, and androgen upregulation, AMPK activation, and restoration of PTEN expression. This editorial emphasizes the reported mechanisms and explains how they act or interact with each other to reduce hepatic steatosis and inflammation in the NASH model. As a perspective, we propose additional mechanisms (such as autophagy/lipophagy activation in hepatocytes) for the clearance of LDs and suppression of hepatic steatosis by MXS in the NASH model. A proper understanding of the mechanisms of MXS-induced reduction of hepatic steatosis might help in the treatment of NASH and related diseases.

Memory in the Halls of Power: The 1903 Ilinden Uprising and Macedonian State-Building
Authors: Vankovska Biljana
Published: November 2024

The article intricately explores the nexus of politics and security enveloping the notion of the Macedonian state, with a specific focus on analyzing the narrative and collective memory tied to the 1903 Ilinden Uprising. As the country marks its 120th anniversary, the state elites and socjety stand at a pivotal juncture, grappling with a pervasive wave of revisionism that extends beyond historiography, permeating public discourse and collective reflections on this seminal historical milestone for the Macedonian people. Even though Ilinden takes its place as a revered national holiday, the trajectory of Macedonian state-building unfolds as a dynamic journey shaped by the intricate interplay of both external and internal influences. The analytical framework employed is rooted in the Copenhagen school of security studies principles, enriched by the foundational tenets of political science and memory studies. This multidisciplinary approach aims to present a perspective on the significant historical event of Ilinden from a non-historian vantage point, offering profound insights into its enduring impact on Macedonian politics and statehood.

Authors: Jang Jae Kyung , Yang Euntae , Kang Geum Choon , Moon Jong-Pil , Yun Sung-Wook
Published: November 2024

Purpose : This study aims to provide basic data for the design and operation of adsorption towers to effectively remove hydrogen sulfide (H2S) from biogas.Methods : Various adsorbents, such as activated carbon, zeolite, and iron sulfate-treated zeolite (Zeolite-Fe7), were used to evaluate the efficiency of H2S removal. The experiments were conducted under different operating conditions, including reactor length, gas flow rate, humidity, and the combined application of absorption and adsorption methods. Key factors influencing the performance of each adsorbent and hydrogen sulfide removal were analyzed.Results and Discussion : Activated carbon recorded the highest H2S removal efficiency at approximately 97.8%, while zeolite and Zeolite-Fe7 showed relatively lower efficiency. The gas flow rate significantly impacted the removal performance of the adsorbents, and reactor length and humidity had varying effects depending on the adsorbent. Additionally, when absorption and adsorption methods were applied simultaneously, a removal rate of about 95.6% was achieved.Conclusion : Activated carbon demonstrated higher efficiency and resistance to humidity compared to other adsorbents, making it the most suitable material for H2S removal from biogas. This study provides basic data for optimizing the design and operation conditions of adsorption towers and is expected to contribute to the future design of pre-treatment processes for H2S removal in biogas.

Authors: Seo Changdong , Yoom Hoonsik , Kang Minsoo , Kim Goeun , Jang Seongho , Son Heejong
Published: November 2024

Objectives : This study aims to evaluate the removal rates of nine cyanotoxins produced by cyanobacteria using a laboratory-scale simulated drinking water treatment process (DWTP), providing useful data for DWTP operations during algal blooms.Methods : A lab-scale simulated DWTP was used to evaluate the removal rates of nine cyanotoxins under typical operating conditions, including specific chemical dosages and contact times. The study employed chlorine and ozone, as well as powdered activated carbon (PAC) and biological activated carbon (BAC).Results and Discussion : According to the experimental results of removal efficiency for chlorination and ozonation, microcystin-LR (MC-LR), MC-RR, MC-LA, MC-LF, MC-LY, MC-YR, cylindrospermopsin (CYN), and nodularin (NOD) were effectively removed within the typical ranges of pre- and post-chlorine and pre- and post-ozone concentrations in the DWTP. However, anatoxin-a (ANA) exhibited a significantly lower removal efficiency. The evaluation of removal efficiency for PAC treatment indicated that MC-LA, MC-LF, and MC-LY had low removal rates. In contrast, the other six cyanotoxins achieved over 50% removal when PAC concentrations were above 25 mg/L and contact times exceeded 30 minutes. The evaluation of removal rate for BAC treatment showed that under conditions with an empty bed contact time (EBCT) of more than 5 minutes, over 70% of the nine cyanotoxins were removed. When the EBCT exceeded 2 minutes, removal rates reached between 95% and 100%. In the BAC process, the removal of MC-RR was primarily facilitated by the biodegradation, while the removal of CYN was mainly achieved through adsorption.Conclusion : Due to climate change, the bloom periods of various cyanobacteria in domestic water sources are gradually increasing, resulting in a rising trend in both the frequency and concentration of detected cyanotoxins. This study evaluated the removal efficiency of various cyanotoxins in DWTPs, focusing on chlorine/ozone treatment (oxidation), PAC treatment (adsorption), and BAC (adsorption and biodegradation). The different DWTPs at the facility act as multiple barriers, effectively removing cyanotoxins upon their introduction.

Published: November 2024

Objectives : This study aimed to explore the potential of halloysite and magnetite powders to enhance anaerobic digestion efficiency and to compare their effects.Methods : Anaerobic digestion experiments were conducted in a total of four consecutive batch processes using reactors with halloysite and magnetite powders added at concentrations of 1 g/L, 10 g/L, and 50 g/L, as well as a control reactor without any powder addition. Cumulative methane production was measured in each batch, and the Gompertz model was applied to calculate kinetic parameters, which were then compared with the control. Additionally, microbial community analysis was performed using 16S rRNA amplicon sequencing, and correlations between the powder concentrations, Gompertz kinetic parameters, and microbial groups were evaluated.Results and Discussion : Both powders demonstrated an effect on improving methane production rates. When halloysite was added at a concentration of 50 g/L, an increase in methane production rate was observed in all batches. Compared to the control, the lag phase (λ) was reduced by up to 31.4%, and the maximum methane production rate (Rm) increased by 17.6%. While the effects of halloysite at concentrations of 1 g/L and 10 g/L were less significant compared to 50 g/L, trends of reduced lag phase and increased Rm were noted in at least two batches. For magnetite powder, the most effective concentration in the first and second batches was 1 g/L, but in the third and fourth batches, lag phase (λ) was reduced by up to 39.3%, and the maximum methane production rate (Rm) increased by 13.2% at concentrations of 10 g/L and 50 g/L. Microbial community analysis revealed an increased dominance of Geobacter and Methanosarcina<>/i associated with the DIET mechanism as the amount of magnetite increased.Conclusion : This study confirms the potential of halloysite and magnetite powders to enhance methane production rates in anaerobic digestion processes. These findings suggest the feasibility of using powdered additives to improve the efficiency of anaerobic digestion, providing foundational data for future related research.
Ahmet Midhat Efendi'nin Romanlarında Türk Kimliğinin İşlenişi

Published: November 2024

Milliyet meselesi, Osmanlı Devleti’nin Tanzimat Dönemi’nde karşılaştığı önemli hususlardan biridir. Bu dönemde Osmanlı Devleti, bünyesinde bulunan her din ve etnik kimlikten grubu, Osmanlılık çatısı altında toplamaya çalışmıştır. Bu dönemde Osmanlılık ideolojisinin ön plana çıkarılmış olması, Osmanlı aydınlarının Türk kimliğinden habersiz olduğu anlamına gelmemektedir. İmparatorluğun kurucu unsurunun Türkler olduğu bilinmektedir. Türklerin devletteki hâkimiyeti ve hâkim dilin Türkçe olması gibi etkenler de eklenince Türk kimliği, Osmanlı kimliğinden ayrı bir şekilde değerlendirilmemiştir. Dönemin yazarları, aynı zamanda birer aydın ve bürokrattırlar. Bu durum, toplumun içerisinde bulunduğu problemleri eserlerinde ele almalarına da sebep olmuştur. Eserlerde Türk kimliğinin ve Türklüğe dair çeşitli tasavvurların girmesi de bu bağlamda söz konusu olmuştur. Tanzimat Dönemi’nde yazı hayatına başlayan ve 1912’de vefatına kadar yazmayı bırakmayan Ahmet Midhat Efendi, romanlarında Türk kimliğini çeşitli yönlerden ele alır. Bu romanlarda Türklerin, kimliklerini en çok Avrupalı milletlerden kişilerle karşılaştıkları zaman idrâk ettikleri görülür. Roman kahramanları Batılılara Türk dilinden ve edebiyatından, Türklerin yaşamından ve kültürlerinden, Türk tarihinden bahsederek Türkleri hem savunurlar hem de tanıtırlar. Bu makalenin amacı, Ahmet Midhat Efendi’nin romanlarında Türk kimliğinin nasıl yer aldığını ele almak ve kendi dönemi içinde ne ifade ettiğini ortaya koymaktır.
Evolution of the EU Approach to Central Asia: from Positive Observer to Geopolitical Player
Authors: Leksyutina Ya. V.
Published: November 2024

In recent years and especially after February 2022, there has been a sharp intensification of Brussels’ engagement with Central Asia. The growing interest in Central Asia is due to the EU’s desire to develop an alternative version of infrastructure development and connectivity in the region as opposed to the China’s Belt and Road Initiative, to use the resource potential of the region to reduce dependence on China for green and digital transition strategy, and the region’s transit potential for development transport and energy infrastructure bypassing Russia. The new geopolitical situation and the trends developing in Central Asia are regarded in Brussels as providing a “window of opportunity” to increase the EU’s presence. Moreover, the EU’s policy towards Central Asia starts to be driven by geopolitical interests. Containing Russia, limiting Russia’s and China’s influence in the region, reducing dependence on China are becoming the main goals of Brussels’ policy in the region. The “benevolent indifference” to the region that once characterized the EU is being replaced by Brussels’ desire to become a major geopolitical player in the region. The article provides a retrospective analysis of the EU policy towards Central Asia throughout the entire period of official interaction between the parties. The focus of the article is to trace the evolution of the goals, priorities and interests of the EU in the region, identify the driving forces that determined Brussels’ policy towards the region at different historical stages, and determine the tools used to achieve the goals. The article also describes the largest EU initiatives for the region. The author concludes that in the current geopolitical situation, Central Asia has no independent significance for Brussels: policy towards the region is built through the prism and in accordance with the logic of confrontation with Russia and hedging risks associated with China.
The Challenges of Crisis Response of the Franco-German Tandem after 2022
Authors: Sokolov A. P.
Published: November 2024

The escalation of the Ukrainian crisis in February 2022 marked a new series of challenges for all key actors in international relations, including the states of the European Union. The largest EU countries France and Germany faced with a set of external and internal crisis phenomena chose different ways to build a strategy to overcome them. The German leadership attempted to use the Ukrainian crisis as a reason for launching previously postponed reforms in Germany and as a source of explanation for economic and social difficulties. Rising inflation, a reduction in industrial production from expensive energy resources, difficulties in migration policy and other problems were explained by Berlin as part of the price for the necessary support for Ukraine. At the same time, the reform of the Bundeswehr, which initially received broad public approval against the backdrop of the start of the Special military operation, faced criticism due to the half-heartedness of the proposed measures. As a result, the German government faced an unprecedentedly low approval rating for its performance, which only exacerbated Germany’s overall state of crisis. On the contrary, the French leadership, faced with a series of internal crises, the central plot of which was pension reform, chose not to tie them to the foreign policy dimension and, in particular, to the events in Ukraine. As a result, the French domestic political discussion did not become dependent on the logic of the development of the situation in Ukraine and was not radicalized at the expense of external participants. The difference in the choice of anti-crisis strategy has strengthened the contradictions within the Franco-German tandem as the economic and political core of the European Union.

The participation of the state in the training of personnel of the armed forces (AF) of another country is a way to ensure a long-term strategic presence in it. But there are high image and practical risks connected with refusal of the recipient country from foreign military instructors, advisers. The article tries to explore the features of the usage of such instrument by Germany on the example of the training of land forces of Afghanistan, Mali and Ukraine. The cases are the missions ISAF (2002-2014) and Resolute Support (2015-2021), EUTM Mali (2013-2022), EUMAM (since December 2022). The author uses 25 criteria divided into 5 groups for the comparative analysis, using the theory of armed forces building.

The paper issues the historic features of the functioning of national armed forces at the territory of three countries, also strategic priorities of the Western democracies during the period of activity of the missions and attitude towards each one from Russia. The reasons of the choice of NATO or the EU for each mission is explained. Also, the author presents the quantitative parameters of the Bundeswehr usage in the cases, different numbers of the trained troops. The important parameters are the features of the organization of them, their composition, timings and schedules of the process, the tactics of combat usage. The research paper concludes about Germany`s desire for the compensation of the losses of former military training tracks by the launch of the new one.
