Catharsis experienced by tennis club participants and its significance
Authors:   Korean Society for Leisure Scie, Choi Yoonseok , Myung Wangsung
Published: June 2024

The purpose of this study was to explore the nature and meaning of catharsis experienced by tennis club participants. 6 research participants who had consistently participated in amateur tennis activities for more than three years and had won at least one prize in amateur competitions were selected. As a result, the research participants experienced ‘catharsis through stress relief,’ ‘catharsis through overcoming fear,’ ‘catharsis through a sense of relative superiority,’ ‘catharsis through imitating professional athletes,’ and ‘catharsis through knowledge and belonging.’ In conclusion, this study found that the catharsis experienced by tennis club participants was not simply a joy or stress relief from physical funtion, but a complex mental effect. These results made it possible to rediscover not only the external but also the internal values of sports, and provided an opportunity to understand amateur tennis culture from a multifaceted perspective.

Authors:   Korean Society for Leisure Scie, Kim Young-Woo , Lee Min-Seok , Lee Chul-Won
Published: June 2024

This study used a phenomenological method to explore the adaptation process of players in an independent baseball team. A snowball sampling method was used to select a total of 12 players who had been playing in an independent baseball team for at least one year, and the data collected was categorized using Giorgi's phenomenological research method. In total, five essential themes emerged. First, the conflict between practical difficulties and individualistic tendencies within independent baseball organizations. Second, the process of entering an independent baseball organization as a possibility and a final challenge. Third, the journey to become a professional baseball player was overcoming adversity while experiencing improvement through continuous efforts. Fourth, they experienced a separation between identity as a baseball player and social identity as a worker. Fifth, the players adapted to the independent baseball organization, reflected on themselves, and prepared for life after retirement. By studying the various life adaptation processes that independent baseball players go through, this study can serve as a cornerstone for the future development of independent baseball organizations.

Otokurmaca: Franz Kafka ve Dava
Authors: Güven Emre Bekir
Published: June 2024

20. yüzyılın gerçeklik algısı ile yakından ilişkili olan “otokurmaca” kavramının, gerçek ile kurmaca ilişkisine bir tepki olarak ortaya çıktığı söylenebilir. Temelde gerçek ve kurmacanın tamamen ayrı noktalarda konumlanmasına rağmen, 20. yüzyıla geçiş sürecinden itibaren artarak birbirlerinin sınırlarına daha fazla geçmeleri, çağdaş insanın gerçek ile kurmaca eksenindeki algısının çökmesine neden olmuştur. Çöken bu algının, esası itibarıyla tartışmalı olan bir tür olan otobiyografi ile birleşmesi ise otokurmacanın ilk alanını oluşturmaktadır. Yazara ait gerçeğe dair bir verinin, kurmaca bir yapıta kimi zaman bilinçsiz, kimi zaman ise kasıtlı olarak yerleştirilmesi durumu romanlarda karşılaşılabilen bir durumdur.
Bu çalışma, Franz Kafka’nın Dava romanı örneği üzerinden otokurmacanın ne olduğunu sorgulamaktadır. Amatörlük sonucu değil, tamamen kasıtlı olarak kendisine ait verileri metne işleyen bir yazar olarak Kafka’nın, yaşadığı bir olayın ardından yazdığı romanda otokurmacaya ne şekilde yer verdiğini irdelemektedir. Çalışmanın amacı, Franz Kafka ve Dava ekseninde otokurmacayı farklı bir açıdan ortaya koymaktır.

The Expanding Attack Surface: Securing AI and Machine Learning Systems in Security Operations
Authors: Christoper Osazuwa Osaro-Mitchell , Ozohu Musa Martha
Published: June 2024

Cyber threats' increasing magnitude and intricacy require a fundamental change in security operations. Conventional approaches face difficulties in keeping up, which exposes organizations to risks. This paper examines the expanding attack surface: securing AI and machine learning systems in security operations as a remedy. A literature review, informed by the Diffusion of Innovation Theory, investigates how organizations absorb innovations in this study. The results demonstrate notable benefits of AI/ML in security, such as superior identification of threats, improved efficiency through automation, and optimized management of vulnerabilities. Nevertheless, achieving successful execution necessitates meticulous deliberation of obstacles. These tasks encompass guaranteeing data accuracy, preserving the capacity to understand how models work, reducing any potential prejudices in AI/ML models, and resolving security weaknesses in the systems themselves. The paper also discusses ethical considerations and emphasizes the important function of human monitoring. To address these difficulties, the study recommends prioritizing data quality, utilizing explainable AI methods, and developing tactics to mitigate bias. Furthermore, there is a strong emphasis on using a human-in-the-loop strategy to take advantage of humans' expertise and machine-learning capabilities. This study highlights the capacity of artificial intelligence and machine learning to transform security operations completely. By confronting the recognized obstacles, organizations may unleash the genuine potential of these technologies and establish a stronger and more proactive security position in response to constantly changing cyber threats.

We report the study of a huge optical intraday flare on 2021 November 12 at 2 a.m. UT in the blazar OJ 287. In the binary black hole model, it is associated with an impact of the secondary black hole on the accretion disk of the primary. Our multifrequency observing campaign was set up to search for such a signature of the impact based on a prediction made 8 yr earlier. The first I-band results of the flare have already been reported by Kishore et al. (2024). Here we combine these data with our monitoring in the R-band. There is a big change in the R–I spectral index by 1.0 ± 0.1 between the normal background and the flare, suggesting a new component of radiation. The polarization variation during the rise of the flare suggests the same. The limits on the source size place it most reasonably in the jet of the secondary BH. We then ask why we have not seen this phenomenon before. We show that OJ 287 was never before observed with sufficient sensitivity on the night when the flare should have happened according to the binary model. We also study the probability that this flare is just an oversized example of intraday variability using the Krakow data set of intense monitoring between 2015 and 2023. We find that the occurrence of a flare of this size and rapidity is unlikely. In machine-readable Tables 1 and 2, we give the full orbit-linked historical light curve of OJ 287 as well as the dense monitoring sample of Krakow.

Authors: Sito Joaquim , Nunes Manuel L , Fonseca Ana Mafalda L
Published: June 2024

Introduction: Human immunodeficiency virus (HIV) / acquired immunodeficiency syndrome (AIDS) infection has been a serious health problem in pediatric age groups globally, and especially in African countries such as Angola. Our aim was to determine the prevalence rate, accumulate incidence rate, and mortality rate of HIV/AIDS infection in children under 14 years of age residing in four municipalities of Malanje (Malanje, Cacuso, Calandula, and Caculama), from 2010 to 2021.
Methodology: This was a documentary research study, with data from 2010 to 2021, developed from a sample size of 10,984 children.
Results: The prevalence rate data showed a certain level of dispersion, and no relationship was identified in its behavior over the years (R2 = 0.0036). On the other hand, the accumulate incidence rate presented a tendency to decrease, indicating a moderate level of correlation in its behavior over the years (R2 = 0.4278). Finally, the mortality rate has been decreasing and presented a high correlation in its association with the years under analysis (R2 = 0.8142). Primary schooling and low purchasing power were frequent (60% and 82%, respectively) among the families of HIV-infected children under study.
Conclusions: Despite the temporal variation of HIV in children under 14 years of age living in the different municipalities, there was a tendency of its diminishing in the later part of the period, from 2010 to 2021. Nevertheless, the key players should focus on strengthening community strategies for prevention, investigation, and diagnosis of HIV infections in this population.

Authors: Li Kui , Liu Siyi , He Yingli , Ran Renyu
Published: June 2024

Introduction: The absence of predictive models for early latent tuberculosis infection (LTBI) progression persists. This study aimed to create a screening model to identify high-risk LTBI patients prome to active tuberculosis (ATB) reactivation.
Methodology: Patients with confirmed ATB were enrolled alongside LTBI individuals as a reference, with relevant clinical data gathered. LASSO regression cross-validation reduced data dimensionality. A nomogram was developed using multiple logistic regression, internally validated with Bootstrap resampling. Evaluation included C-index, receiver operating characteristic (ROC) curve, and calibration curves, with clinical utility assessed through decision curve analysis.
Results: The final nomogram incorporated serum albumin (OR = 1.337, p = 0.046), CD4+ (OR = 1.010, p = 0.004), and CD64 index (OR = 0.009, p = 0.020). The model achieved a C-index of 0.964, an area under the ROC curve of 0.962 (95% CI: 0.926–0.997), sensitivity of 0.971, and specificity of 0.910. Internal validation showed a mean absolute error of 0.013 and 86.4% identification accuracy. The decision curve indicated substantial net benefit at a risk threshold exceeding 10% (1: 9).
Conclusions: This study established a biologically-rooted nomogram for high-risk LTBI patients prone to ATB reactivation, offering strong predictability, concordance, and clinical value. It serves as a personalized risk assessment tool, accurately identifying patients necessitating priority prophylactic treatment, complementing existing host risk factors effectively.

Published: June 2024

Introduction: Human immunodeficiency virus (HIV) / hepatitis B virus (HBV) causes higher rates of liver disease compared to infection with just one virus. Co-infection can accelerate the progression to liver fibrosis or hepatocellular carcinoma and disturb the treatment response. APOBEC3G is a host defense factor which interferes with HIV-1 and HBV. We aimed to determine the prevalence of hepatitis B surface antigen (HBsAg) among HIV-infected patients and seronegative controls, and screen the HIV/HBV population for APOBEC3G variants rs8177832, rs35228531 and rs2294367, previously associated with HIV-1 infection susceptibility in Morocco.
Methodology: A case control study was conducted on 404 individuals (204 HIV-infected and 200 eligible blood donors) from April to November 2021. HBsAg was measured on the Roche Cobas e411 automatic analyzer (Roche Diagnostics, Basel, Switzerland) and APOBEC3G polymorphisms were identified using the TaqMan genotyping allelic discrimination method. Fisher Exact test, odds ratio (OR) with 95% confidence interval (CI), and haplotype frequencies were calculated.
Results: Of the 204 HIV-1 seropositive patients and 200 controls, 4.9% (95%CI: 2.38-8.83) and 2.50% (95% CI: 0.82-5.74) were HBsAg-positive respectively. There was a significant association between increasing age (> 40 years) and HBV infection among controls (p = 0.04). The distribution of genotypes and alleles frequencies of APOBEC3G variants was heterogenous and five different haplotypes with frequencies ≥ 5% were obtained, of which ACC (rs8177832, rs35228531, rs2294367) was the most prevalent.
Conclusions: HBV co-infection is common among HIV-1 infected individuals in Morocco. Efforts should be made to prevent, treat and control HBV transmission in this population.

Introduction: Tuberculous lymphadenitis (TBLN) is the most common infectious etiology of peripheral lymphadenopathy in adults, in Turkiye. This study aimed to identify the demographic, clinical, and laboratory variables that differentiate TBLN from non-tuberculous lymphadenitis (NTBLN), as well as the etiology of lymphadenopathy in adults.
Methodology: Patients who were over 18 years old and were referred to the infectious disease outpatient clinics with complaints of swollen peripheral lymph nodes, and who underwent lymph node biopsy between 1 January 2010 and 1 March 2021, were included in this multicenter, nested case-control study.
Results: A total of 812 patients at 17 tertiary teaching and research hospitals in Turkiye were included in the study. TBLN was the most frequent diagnosis (53.69%). The proportion of patients diagnosed with TBLN was higher among females; and among those who had a higher erythrocyte sedimentation rate, positive purified protein derivative test, and positive interferon-gamma release test result (p < 0.05). However, TBLN was less frequent among patients with generalized lymphadenopathy, bilateral lymphadenopathy, axillary lymphadenopathy, inguinal lymphadenopathy, hepatomegaly, splenomegaly, leukocytosis, and moderately increased C reactive protein levels (p < 0.05).
Conclusions: Identifying the variables that predict TBLN or discriminate TBLN from NTBLN will help clinicians establish optimal clinical strategies for the diagnosis of adult lymphadenopathy.

The study presents a new look on the socio-ecological relations in retrospective, focusing on their formation and adaptation over time in Velingrad Municipality, Bulgaria. The dependencies between the main components of the system are outlined and the main disturbances in terms of presses and pulses are examined. Examples of trade-offs and synergies are also offered to better understand the cross-scale dynamics of the studied components. The reaction of the system to pulses in its growth phase of the adaptive cycle is reviewed. In addition, the contemporary state of the main components of the coupled human-natural system is analysed in order to identify the slow and fast variables that determine the trajectory of the system at present. The resilience thinking concept is applied in analyzing the processes within the coupled human-natural system and in identifying the mechanisms that may enhance its capacity to absorb shocks.
Faculty and Staff Nurse Perspectives on Collaboration in Clinical Learning
Authors: Hooven Katie
Published: June 2024

The benefits of collaboration between nursing faculty members and staff nurses in the clinical learning environment are well established. Unfortunately, little is known about improving collaboration to benefit student learning. Descriptive methods were used to examine perceptions of faculty and staff nurses’ collaboration in clinical environments. Data was collected from 497 participants via online Qualtrics survey. Participants were divided into three groups: staff nurses, nursing faculty members, and nurses who worked concurrently in academia and practice. Content analysis procedures were used along with NVivo Pro (Version 11, www.lumivero.com). Four themes were identified: expectations, coordination, communication, and courtesy. Results support that academia and practice professionals wish to work together, but often have different perceptions of each other’s roles. Implications for faculty and staff nurses to improve collaboration are discussed.
Discriminative Nursing Care Practices Towards Patients with Opioid Use Disorder in the Hospital Setting: An Integrative Review
Authors: Bernier Jeanne , Barroso Cristina
Published: June 2024

Discriminative nursing care (DNC) is the act of a nurse treating a patient differently from another patient based on the patient’s illness, diagnosis, lifestyle, personal choices, age, or socio-demographic status. As such, the patient perceives a variation in treatment. Health-related stigma and stereotyping contribute to DNC, especially towards patients with opioid use disorder (OUD) during hospitalization. This integrative review considered recent relevant literature related to DNC practices towards patients with OUD in the hospital setting to identify discriminatory actions and potential causes and to provide known and new recommendations to address DNC practices towards this patient population. Literature from 2016-2022 (n = 13) was searched and analyzed, revealing four emerging themes: Patients’ Perceptions of DNC, Nurses and Other Healthcare Providers’ Perceptions of DNC, Nurses’ Lack of Understanding, and Recommendations for Improvement. In this article, we discuss specific findings related to each theme, gaps in the current literature, additional recommendations, and important considerations for future research.

The mitochondrion is a vital intracellular organelle that is responsible for ATP production. It utilizes both the concentration gradient and the electrical potential of the inner mitochondrial membrane to drive the flow of protons from the intermembrane space to the matrix to generate ATP via ATP-synthase. However, the proton leak flow, which is mediated via the inner mitochondrial membrane and uncoupling proteins, can reduce the efficiency of ATP production. Protons can exhibit a quantum behavior within biological systems. However, the investigation of the quantum behavior of protons within the mitochondria is lacking particularly in the contribution to the proton leak. In the present study, we proposed a mathematical model of protons tunneling through the inner mitochondrial membrane and the mitochondrial carrier superfamily MCF including uncoupling proteins UCPs and the adenine nucleotide translocases ANTs. According to the model and its assumptions, the quantum tunneling of protons may contribute significantly to the proton leak if it is compared with the classical flow of protons. The quantum tunneling proton leak may depolarize the membrane potential, hence it may contribute to the physiological regulation of ATP synthesis and reactive oxygen species ROS production. In addition to that, the mathematical model of proton tunneling suggested that the proton-tunneling leak may depolarize the membrane potential to values beyond the physiological needs which in turn can harm the mitochondria and the cells. Moreover, we argued that the quantum proton leak might be more energetically favorable if it is compared with the classical proton leak. This may give the advantage for quantum tunneling of protons to occur since less energy is required to contribute significantly to the proton leak compared with the classical proton flow.
A reliable numerical algorithm for fractional Lienard equation arising in oscillating circuits
Authors: Singh Jagdev , Kumar Jitendra , Kumar Devendra , Baleanu Dumitru
Published: June 2024

This work presents a numerical approach for handling a fractional Lienard equation (FLE) arising in an oscillating circuit. The scheme is based on the Vieta Lucas operational matrix of the fractional Liouville-Caputo derivative and the collocation method. This methodology involves a systematic approach wherein the operational matrix aids in expressing the fractional problem in terms of non-linear algebraic equations. The proposed numerical approach utilizing the operational matrix method offers a vital solution framework for efficiently tackling the fractional Lienard equation, addressing a key challenge in mathematical modeling. To analyze the fractional order system, we derive an approximate solution for the FLE. The solutions are explained graphically and in tabular form.
1980-1990: dels teatres per a Catalunya a les pràctiques escèniques dels catalans. Reflexions identitàries sobre el fet teatral al llarg de la primera dècada de la Catalunya autonòmica
Authors: Corrons Fabrice
Published: June 2024

Dans cette contribution, nous cherchons à analyser l'évolution de l'identité du « théâtre catalan » dans l'Espagne des années 1980 qui, dans un mouvement de démocratisation et à travers le système constitutionnel des Autonomies, a donné beaucoup plus de pouvoir au gouvernement catalan en matière de culture. Comment donc se transforment les paramètres identitaires d'un théâtre marqué par quarante ans de régime dictatorial contraire à l'épanouissement d'une conscience « nationale » catalane et ainsi opposé au développement de la langue et la culture catalanes ?

Les jeux vidéo sont aujourd’hui reconnus par de nombreux cliniciens et chercheurs comme des outils très pertinents dans la prise en charge des enfants et des adolescents. Le présent article a pour objectif de s’inscrire dans la continuité de ces travaux, en cherchant plus précisément à se focaliser sur une utilisation spécifique de ce médium dans la clinique des adolescents : la co-création d'un jeu vidéo. Nous avons ainsi mis en place, dans un centre médico-psycho-pédagogique (C. M. P. P.) et dans un hôpital de jour pour enfants et adolescents, deux ateliers thérapeutiques basés sur l’utilisation du logiciel RPG Maker, afin d’accompagner les patients dans la programmation de leur propre jeu vidéo. Cet article a pour objectif de présenter ce temps de thérapie groupale mélangeant une médiation numérique et une médiation passant par l’écriture (ici sous la forme d’un langage de programmation basique).

Dans le cadre d’un projet de recherche destiné à améliorer les techniques d’analyse d’imagerie médicale, notamment employées pour repérer ou suivre certains cancers, nous avons mené une étude de recherche création. Celle-ci s’est focalisée sur la création d'un jeu de société sérieux visant à aborder de manière ludique les bénéfices et les limites de différentes techniques. Dans cette optique, nous avons exploré diverses solutions ludo-sérieuses vers lesquelles nous diriger, ce qui nous a mené à une analyse des processus pouvant être mobilisés. Nous présentons ici une revue de la littérature scientifique à ce sujet et clarifions les différentes formes d'applications pratiques qui émanent plus ou moins du concept de jeu, en les catégorisant. Par la suite, nous examinons les processus considérés pour élaborer un jeu de plateau à but utilitaire et plus particulièrement à but de partage de points de vue. Nous détaillons ainsi les étapes de conception que nous avons suivies, en mettant en évidence les diverses démarches employées et le résultat accompli.

Vasorelaxant effects of biochemical constituents of various medicinal plants and their benefits in diabetes
Authors: Demirel Sadettin
Published: June 2024

Endothelial function plays a pivotal role in cardiovascular health, and dysfunction in this context diminishes vasorelaxation concomitant with endothelial activity. The nitric oxide-cyclic guanosine monophosphate pathway, prostacyclin-cyclic adenosine monophosphate pathway, inhibition of phosphodiesterase, and the opening of potassium channels, coupled with the reduction of calcium levels in the cell, constitute critical mechanisms governing vasorelaxation. Cardiovascular disease stands as a significant contributor to morbidity and mortality among individuals with diabetes, with adults afflicted by diabetes exhibiting a heightened cardiovascular risk compared to their non-diabetic counterparts. A plethora of medicinal plants, characterized by potent pharmacological effects and minimal side effects, holds promise in addressing these concerns. In this review, we delineate various medicinal plants and their respective biochemical constituents, showcasing concurrent vasorelaxant and anti-diabetic activities.

Diabetic foot ulcers (DFUs) pose a critical medical challenge, significantly im-pairing the quality of life of patients. Adipose-derived stem cells (ADSCs) have been identified as a promising therapeutic approach for improving wound healing in DFUs. Despite extensive exploration of the mechanical aspects of ADSC therapy against DFU, its clinical applications remain elusive. In this review, we aimed to bridge this gap by evaluating the use and advancements of ADSCs in the clinical management of DFUs. The review begins with a discussion of the classification and clinical management of diabetic foot conditions. It then discusses the current landscape of clinical trials, focusing on their geographic distribution, reported efficacy, safety profiles, treatment timing, administration techniques, and dosing considerations. Finally, the review discusses the preclinical strategies to enhance ADSC efficacy. This review shows that many trials exhibit biases in study design, unclear inclusion criteria, and intervention protocols. In conclusion, this review underscores the potential of ADSCs in DFU treatment and emphasizes the critical need for further research and refinement of therapeutic approaches, with a focus on improving the quality of future clinical trials to enhance treatment outcomes and advance the field of diabetic wound care.
Subclinical impairment of left ventricular myocardium function in type 2 diabetes mellitus patients with or without hypertension
Authors: Chen Zeng-Guang , Li Guang-An , Huang Jun , Fan Li
Published: June 2024

BACKGROUND

Cardiovascular disease has been the leading cause of morbidity and mortality for type 2 diabetes mellitus (T2DM) patients over the last decade.

AIM

To determine whether layer-specific global longitudinal strain (GLS) combined with peak strain dispersion (PSD) can be used to assess left ventricle (LV) myocardium systolic dysfunction in T2DM patients or without hypertension (HP).

METHODS

We enrolled 97 T2DM patients, 70 T2DM + HP patients and 101 healthy subjects. Layer-specific GLS and PSD were calculated by EchoPAC software in apical three-, four- and two-chamber views. GLS of the epimyocardial, middle-layer and endomyocardial (GLSepi, GLSmid, and GLSendo) were measured and recorded. Receiver operating characteristic analysis was performed to detect LV myocardium systolic dysfunction in T2DM patients.

RESULTS

There were significant differences in GLSepi, GLSmid, GLSendo, and PSD between healthy subjects, T2DM patients and T2DM patients with HP (P < 0.001). Trend tests yielded the ranking of healthy subjects > T2DM patients > T2DM with HP patients in the absolute values of GLSepi, GLSmid and GLSendo (P < 0.001), while PSD was ranked healthy subjects < T2DM < T2DM with HP (P < 0.001). Layer-specific GLS and PSD had high diagnostic efficiency for detecting LV myocardium systolic dysfunction in T2DM patients, however, the area under the curve (AUC) for layer-specific GLS and PSD combined was significantly higher than the AUCs for the individual indices (P < 0.05).

CONCLUSION

Layer-specific GLS and PSD were associated with LV myocardium systolic dysfunction in T2DM patients, T2DM patients with HP. T2DM patients with HP have more severe LV myocardium systolic dysfunction than T2DM patients without HP and normal control patients. The combination of layer-specific GLS and PSD may provide additional prognostic information for T2DM patients with or without HP.
Mapping and Assessment of Ecosystem Services Supply and Demand of the Kilombero Valley Floodplain, Tanzania

Effective land use planning requires mapping and assessing ecosystem service supply and demand to inform policy and decision-makers about ecosystem service tradeoffs that are suited for long-term ecological management. This study examined the ecosystem services supply and demand of the Kilombero Valley Floodplain in Southeastern Tanzania. The supply-demand budget index was calculated using land use data from 1990, 2010, and 2016 and an expert-based matrix model examined the dynamic change of supply and demand for the 17 ecosystem services (7 regulating, 8 provisioning, and 2 cultural). The spatial analytic features of ArcGIS 10.2 were utilized to build ecosystem services evaluation matrices and regionally explicit supply, demand, and supply-demand budget maps. The study found that between 1990 and 2016, the supply of ecosystem services within the Kilombero Valley floodplain decreased substantially while the demand for ecosystem services increased spatially towards the core low-lying area of the valley. Furthermore, the average ecosystem service supply-demand budget index declined from 1.8 in 1990 to 1.6 in 2016, with few exceptions of food production, pollination, and freshwater supply, where ecosystem service supply exceeds demand. The decline is linked to deforestation, agricultural expansion, agropastoralists immigration, and encroachment to the wetland area. Thus, this study recommends that the government should create effective land use plans for each ward and village in the Kilombero District, establish afforestation programs, local irrigation schemes for smallholder farmers, and enforce environmental by-laws to ensure sustainable ecological management in the Kilombero Valley Floodplain and its ecosystems.

Plastic pollution is recorded in terrestrial and aquatic ecosystems. Plastic waste exposed to the environment causes many problems for the environment and all forms of life. This study was conducted to evaluate the microplastic pollution in sediments at the Han River estuary (Da Nang). The analysis results at 8 survey locations showed that microplastics appeared in all samples and there was heterogeneity in density at 8 locations, ranging from 348.2÷3567.8 MPs/kg. Microplastic sizes in the range of 50÷150 μm account for the highest proportion with a value of 2531 MPs/kg, followed by sizes > 500; 20÷50; 50÷150, and 300÷500 μm with ratio values of 2034.2; 1292.1; 842.1, and 595.9 MPs/kg, respectively. The fibers and fragment microplastic forms accounted for most sediment samples up to 98.6%, the white color of microplastic recorded an average value of 49.8%, accounting for nearly half of the microplastics total found. FTIR spectrum shows that PET (Polyethylene Terephthalate) polymer has the highest density with 38.7%; followed by Polyester 25.1%; Nylon 12.9%; Polypropylene 5.4%; remaining polymers such as PVC (polyvinylchloride), PS (polystyrene), PE (Polyethylene), HDPE (High Density Polyethylene), etc. account for a fairly low proportion ranging from 0.7÷2.7%. This source of microplastic pollution is closely related to civil and service activities on both sides of the river. Therefore, in addition to changing environmental management measures, it is nessesary to research to understand the mechanisms that affect the transport, deposition, and interactions of microplastics with organisms living in this sediment environment.
