PERSON-NUMBER ASYMMETRY: AGREEMENT OF PASSIVE MIRATIVES IN KAZYM KHANTY
Authors: Старченко А.М. , Толдова С.Ю.
Published: December 2023

Работа рассматривает ранее не засвидетельствованную модель расщеплённого согласования в парадигме миратива в казымском диалекте хантыйского языка. Расщеплённое согласование выявляется при сравнении активной и пассивной миративных конструкций, а также в ограниченном наборе употреблений нефинитных форм и выражается в том, что в пассивном залоге, в отличие от активного, 3 лицо немаркировано — наблюдается согласование только по числу. При этом согласовательные показатели 1 и 2 лица выглядят одинаково вне зависимости от диатезы. В других парадигмах хантыйского глагола, в частности, в субъектном и объектном индикативе расщепления не наблюдается. Работа подробно характеризует выявленную модель согласования, соотнося её фрагменты с другими словоизменительными парадигмами казымского диалекта хантыйского языка: субъектным и объектным спряжениями индикатива, посессивной парадигмой и именными показателями числа. В исследовании выдвигается гипотеза о том, что для полноценного, недефектного согласования по лицу хантыйской именной группе требуется или достаточно высокая синтаксическая позиция (внешний аргумент), или полноценный набор признаков лица, которым обладают местоимения 1–2 лица. Работа также рассматривает хантыйские данные в свете типологии расщеплённого согласования.

The study focuses on a previously unrecorded model of split agreement in the mirative paradigm in Kazym Khanty. Split agreement is found when comparing active and passive mirative constructions, as well as in a limited set of uses of non-finite forms. In the passive voice, unlike the active voice, the 3rd person is unmarked and the subject only agrees in number. At the same time, the agreement markers of the 1st and 2nd persons are the same regardless of the diathesis. In other paradigms of the Khanty verb, in particular, in the subject and object indicative, the split is not observed. The work characterizes in detail the identified agreement model, matching its fragments with those of other inflectional paradigms of Kazym Khanty: subject and object conjugations of the indicative, possessive paradigm and nominal number markers. The study puts forward a hypothesis that for full-fledged, non-defective person agreement, the Khanty nominal group must have either a sufficiently high syntactic position (external argument), or a full set of person features, which are possessed by 1–2 person pronouns. The work also examines the Khanty data in the light of the typology of split agreement.

Published: December 2023

Este trabalho defende que a subversão que Nietzsche aplica ao atributo da universalidade referido ao humano implica a compreensão de cinco conceitos que, na sua sistematicidade, unicamente permitem a relação desse atributo ao seu referente. O conceito de “niilismo” é, inicialmente, explicitado quanto aos seus aspectos passivo e ativo e Nietzsche é definido como um niilista ativo. O conceito do “transvaloração dos valores” é, em seguida, colocado como o guia para a afirmação dos valores do ser humano e da relação deste com o mundo, com a natureza e com outros humanos. O conceito de “além-do-homem”, na sua contraposição ao conceito de “homem superior”, é, depois, definido como o responsável pela horizontalidade progressiva e pela totalidade constitutiva do sentido do humano. O conceito de “vontade de potência” é, na sequência, elucidado como aquele que integra todas as formas de vida e que permite, assim, também ao homem o seu aprimoramento. O conceito de “amor fati” é, por fim, dado como a necessidade de amar a totalidade da vida enquanto imprescindível à constituição do humano. O resultado da pesquisa é o de que tais conceitos constituem uma proposta (in)crível para se pensar o humano na sua universalidade.

Published: December 2023

Mental health is a fundamental component of the World Health Organization's definition of health, encompassing not only freedom from illness but also well-being in physical, mental, and social dimensions. In today's modern society, mental health has become a paramount issue, as its soundness enables individuals to realize their own potential, cope with normal life pressures, work productively, and contribute effectively to their communities. In Indonesia, mental health-related challenges are associated with the absence of a reliable mental health detection tool. Conversely, abroad, there has been a substantial amount of research focused on innovative technology-based mental health detection using Machine Learning. This study aims to predict mental health using the Social Emotional Health Survey-Secondary (SEHS-S) as the evaluation criterion for prediction through Machine Learning. The Decision Tree algorithm is employed, and the prediction model is tested using K-Fold Cross-Validation, resulting in 8 folds with an accuracy rate of 78.61%.
A Computational Approach for Score-Level Fusion Decision-Making of Multi-biometric Recognition System Using Ant Colony Optimisation
Authors: Manvi Khatri  , Ajay Sharma
Published: December 2023

This study presents a novel deep learning approach for improving the performance of a multi-biometric recognition system using Ant Colony Optimisation (ACO) at the score level. The proposed method integrates three biometric characteristics, the face, palm, and iris, into a single recognition input. A deep learning model, convolutional neural networks (CNNs), is employed to extract discriminative features from each attribute. The ACO algorithm optimizes the score-level fusion procedure, in which recognition scores from the combined input are combined to make the final determination. The experimental results show the method's efficacy in selecting the score level fusion method per the input biometric and implementation parameters. The ACO-based score-level fusion improves system performance by leveraging complementary information from multiple biometric characteristics, providing a promising solution for robust and accurate multi-biometric recognition in various applications, including access control and identity verification.

RELATIONSHIP BETWEEN GOOGLE SEARCH VOLUME AND FLOOD EVENTS IN INDONESIA: A GOOGLE TRENDS ANALYSIS
Authors: RESTI KINANTHI  , Mochammad Iqbal
Published: December 2023

The increasing number of floods every year brings a wide impact; the average loss caused by floods every year reaches 4.64T (Rp). Information about floods is very important to improve the preparedness of people living in disaster-prone areas. If information can be provided when people have a high interest in learning, it can have a profound effect on increasing public knowledge. To carry out effective risk communication in flood disasters, knowledge about flood disaster patterns is needed, as well as knowledge about community behavior in seeking information. One of the people's behavior in searching for information can be seen from the Google Trends analysis. The purposes of this study are to analyse the relationship between public interest in finding information through google trends with the keyword "flood" with flood events in Indonesia for 10 years. This research is a quantitative descriptive study by processing data obtained from Google Trends and BNPB flood event data using the Spearman Rank Correlation statistical test with SPSS software. The results showed that Google Trends with the keyword "Flood" and the pattern of flood events had a strong positive relationship with a correlation coefficient of 0.64, this indicates that the increase in the incidence of disasters causes an increase in public interest in seeking information about flood disasters. Risk communication that was carried out before the disaster occurred was not yet optimal in reaching the community. Risk communication needs to be carried out before the months that are predicted to be the peak of flood events. Risk communication is carried out to form the preparedness of the Indonesian people so that the risk of flood disasters can be reduced.

Published: December 2023

Fertility is an important component of quality of life and oncological patients should be questioned about their expectations before treatment. Radiotherapy (RT) can adversely affect fertility irreversibly and progressively. Therefore, patients with expectation of fertility should be evaluated before RT and guided for appropriate interventions. Radiotherapy negatively affects fertility in many aspects. Cranial RT disrupts the hypothalamus-pituitary-ovarian (H-P-O) axis, pelvic RT directly affects the ovary and uterus. Because of the long latent period of endocrinopathies caused by cranial RT, these patients should be followed up for a long time. Due to dose-dependent uterine and ovarian toxicities that develop after abdominopelvic RT, patients are at high risk for infertility and pregnancy complications. Uterus and ovaries have different radiosensitivity depending on age. With aging, radiosensitivity of the uterus decreases, while radiosensitivity of the ovaries increase. Although there is no consensus on the threshold doses that can cause RT-related infertility, according to current data, the threshold value for the hypothalamo-pituitary axis is 30 Gy; 25 Gy for young women and 45 Gy for adult women for the uterus; 10 Gy for acute ovarian failure in the ovary and 25 Gy for premature ovarian failure under 35 years of age. There is no significant relationship between parental radiation exposure and inherited genetic disease in their infants.

Published: December 2023

The main purpose of the study is to optimize local aspects of state regulation of ensuring the safety and security of enterprises in the context of sustainable development in a particular region. For this purpose, a new methodical approach was presented using simulation optimization of the processes of ensuring safety and security of security of enterprises in the context of sustainable development. The study focuses on enterprises and their safety and security systems security in the context of sustainable development. The relevance of the study is given by the fact that most enterprises in many regions suffer from ineffective regulation at the local level. At the same time, in most cases, state regulation does not take into account all aspects of safety and security in the context of sustainable development. The research methodology involves the use of a modern method of process optimization modeling. As a result, a model for optimizing local aspects of state regulation of business safety and security for a specific, selected region in the context of sustainable development was presented. The research has limitations and they consist of the selection of only one region and the consideration of local aspects of enterprises of certain socio-economic systems. Prospects for further research will be devoted to expanding modeling and taking into account a larger number of enterprises in the context of sustainable development.
SIMULATING VICTIM HEALTH STATE EVOLUTION FROM PHYSICAL AND CHEMICAL INJURIES IN MASS CASUALTY INCIDENTS
Authors: Benhassine Mehdi , De Rouck Ruben , Debacker Michel , Hubloue Ives , Dhondt Erwin , Van Utterbeeck Filip
Published: December 2023

The field of discrete-event simulation for medical disaster management is relatively new. In such simulations, human victims are generated using pre-determined transitions from one health state to the next, based on a set of triggers that correspond to treatment or the clinical progression of untreated injuries or diseases. However, this approach does not account for subtle differences in clinical progression. We propose a parameter-based model to characterize the evolution of symptoms at first for physical and nerve agent chemical injuries. We used a Gompertz function to predict the time of death in trauma based on forensic data. Then we separately considered the effects of the chemical warfare agent sarin (GB) being the origin of the chemical injuries for the purpose of modelling a GB attack in a metro station. We emphasize that our approach can be extended to other CBRN threats pending knowledge of clinical progressions available in the literature for the purpose of casualty estimations. The intent is to provide an estimate of time to death without any treatment and overlay this model with a treatment model, improving the evolution of the health state. A modification for non-life-threatening injuries is included without losing generality. Improvement functions modelling medical treatment are proposed. We argue that the availability of injury scores vs mortality can greatly enhance the validity of the model.
Determination of the Branching Ratio of CH3OH + OH Reaction on Water Ice Surface at 10 K
Authors: Ishibashi Atsuki , Hidaka Hiroshi , Sameera W. M. C. , Oba Yasuhiro , Watanabe Naoki
Published: December 2023

The CH3O and CH2OH radicals can be important precursors of complex organic molecules (COMs) in interstellar dust. The COMs presumably originating from these radicals were abundantly found in various astronomical objects. Because each radical leads to different types of COMs, determining the abundance ratio of CH3O to CH2OH is crucial for a better understanding of the chemical evolution into various COMs. Recent work suggested that the reaction between CH3OH and OH on ice dust plays an important role in forming CH3O and CH2OH radicals. However, quantitative details on the abundance of these radicals have not been presented to date. Herein, we experimentally determined the branching ratio (CH3O/CH2OH) resulting from the CH3OH + OH reaction on the water ice surface at 10 K to be 4.3 ± 0.6. Furthermore, the CH3O product in the reaction would participate in subsequent diffusive reactions even at a temperature as low as 10 K. This fact should provide critical information for COMs formation models in cold molecular clouds.
Disentangling Stellar Age Estimates from Galactic Chemodynamical Evolution

Published: December 2023

Stellar ages are key for determining the formation history of the Milky Way, but are difficult to measure precisely. Furthermore, methods that use chemical abundances to infer ages may entangle the intrinsic evolution of stars with the chemodynamical evolution of the Galaxy. In this paper, we present a framework for making probabilistic predictions of stellar ages, and then quantify the contribution of both stellar evolution and Galactic chemical evolution to those predictions using SHapley Additive exPlanations. We apply this interpretable prediction framework to both a simulated Milky Way sample containing stars in a variety of evolutionary stages and an APOGEE-mocked sample of red clump stars. We find that in the former case, stellar evolution is the dominant driver for age estimates, while in the latter case, the more restricted evolutionary information causes the model to proxy ages through the chemical evolution model. We show that as a result of the use of nonintrinsic Galactic chemical information, trends estimated with the predicted ages, such as the age–metallicity relation, can deviate from the truth.
The Influence of Cold Jupiters in the Formation of Close-in Planets. I. Planetesimal Transport
Authors: Best Marcy , Sefilian Antranik A. , Petrovich Cristobal
Published: December 2023

The formation of a cold Jupiter (CJ) is expected to quench the influx of pebbles and the migration of cores interior to its orbit, thus limiting the efficiency of rocky planet formation either by pebble accretion and/or orbital migration. Observations, however, show that the presence of outer CJs (>1 au and ≳0.3M
Jup) correlates with the presence of inner super-Earths (at <1 au). This observation may simply be a result of an enhanced initial reservoir of solids in the nebula required to form a CJ or a yet-to-be-determined mechanism assisted by the presence of the CJ. In this work, we focus on the latter alternative and study the orbital transport of planetesimals interior to a slightly eccentric (∼0.05) CJ subject to the gravity and drag from a viscously evolving gaseous disk. We find that a secular resonance sweeping inward through the disk gradually transports rings of planetesimals when their drag-assisted orbital decay is faster than the speed of the resonance scanning. This snowplow-like process leads to large concentration (boosted by a factor of ∼10–100) of size-segregated planetesimal rings with aligned apsidal lines, making their expected collisions less destructive, due to their reduced velocity dispersion. This process is efficient for a wide range of α-disk models (and thus disk lifetimes) and Jovian masses, peaking for values ∼1–5M
Jup, which are typical of observed CJs in radial velocity surveys. Overall, our work highlights the major role that the disk's gravity may have on the orbital redistribution of planetesimals, depicting a novel avenue by which CJs may enhance the formation of inner planetary systems, including super-Earths and perhaps even warm and hot Jupiters.

Published: December 2023

We construct a new catalog of the blue horizontal-branch (BHB) stars from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) DR5 data set, which contains 5355 + 81 BHB stars at high Galactic latitude (∣Glat∣ > 20°). We combine the spectral line indices with a set of Balmer line profile selection criteria to identify the BHB stars. During the selection process, we use the line index of Ca ii K to exclude the metal-rich A-type dwarfs. We obtain their atmospheric parameters by crossmatching our BHB stars with the catalog provided by Xiang et al. The results show that our sample is consistent with the theoretical T
eff–log g evolutionary tracks of the BHB stars, indicating that our method is robust for identifying BHB stars from the LAMOST spectra. Their spatial distribution indicates that most of our BHB stars are located in the inner halo or the disk of the Milky Way. Combined with other BHB samples from the literature, the BHB stars can cover a large Galactic volume, which makes them a better probe for studying the kinematics, dynamics, and structural characteristics of the Milky Way.

Cygnus X-1, the well-known accreting black hole system, exhibits several observational features hinting at an intricate interplay between the accretion disk, its atmosphere known as the corona, and the putative relativistic jet. It has been extensively studied using all available observational methods, including using the newly available technique of sensitive X-ray polarimetry. X-ray polarization characteristics are distinct for coronal and jet emissions. The low X-ray polarization measured below ∼100 keV is understood as arising from the corona. In contrast, the high polarization measurements reported above ∼400 keV required a separate jet-dominated spectral component, which spectroscopy does not demonstrate conclusively. Here we report precise polarization measurements in the 100–380 keV region made during three different subclasses of spectral states of the source using the CZTI instrument onboard AstroSat. A high polarization (23% ± 4%) is found mainly in the Intermediate Hard State of the source, and the energy-resolved measurements smoothly connect the coronal and the jet regimes. When high polarization is observed, the simultaneous spectral data hints at a separate power-law component above 100 keV. We examine the possible sources of this energy-dependent high polarization in Cygnus X-1.

Introduction: There are numerous imaging modalities available to describe pancreatic parenchyma. None of the broadly accepted diagnostic methods uses elasticity as an indicator of tissue damage.

Aim: The aim of the present study was to establish reference values of parenchymal stiffness of normal pancreatic parenchyma through point shear wave elastography.

Materials and methods: The design of the study is prospective single-center cohort study. Sixty patients were included in the study. The ultrasound-based point shear wave elastography (pSWE) imaging technique was applied. The mean and median shear wave velocity values of the pancreatic parenchyma in the head, body and tail were calculated. The influence of certain variables on the shear wave velocity (SWV) values was estimated.

Results: A reference range for the entire pancreatic parenchyma of 0.66-1.62 m/s and a mean value of 1.17±0.22 m/s were calculated. Apart from age, none of the evaluated factors proved to have statistically significant influence on the obtained results. A measurement success rate of 94.5%, 97.2%, and 95.8% was established for the head, body, and tail of the pancreas, respectively.

Transabdominal pSWE could be utilized for assessment of pancreatic parenchyma with high success rate. A mean value of 1.17 m/s was measured which is consistent with the existing literature on the matter. None of the external factors examined in the study, apart from age, was found to have statistically significant influence on the SWV values.

Conclusions: The obtained results suggest that pSWE is a highly objective method for evaluating pancreatic parenchyma. Calculated reference range and mean values could be used in future studies to assess the capabilities of the method for differentiating between normal pancreatic parenchyma and diffuse and focal pancreatic disorders.

Published: December 2023

A particularly useful assessment tool for evaluating uncertainty and dealing with fuzziness is the Fermatean fuzzy set (FFS), which expands the membership and non-membership degree requirements. Distance measurement has been extensively employed in several fields as an essential approach that may successfully disclose the differences between fuzzy sets. In this article, we discuss various novel distance measures in Fermatean hesitant fuzzy environments as research on distance measures for FFS is in its early stages. These new distance measures include weighted distance measures and ordered weighted distance measures. This justification serves as the foundation for the construction of the generalized Fermatean hesitation fuzzy hybrid weighted distance (DGFHFHWD) scale, as well as the discussion of its weight determination mechanism, associated attributes and special forms. Subsequently, we present a new decision-making approach based on DGFHFHWD and TOPSIS, where the weights are processed by exponential entropy and normal distribution weighting, for the multi-attribute decision-making (MADM) issue with unknown attribute weights. Finally, a numerical example of choosing a logistics transfer station and a comparative study with other approaches based on current operators and FFS distance measurements are used to demonstrate the viability and logic of the suggested method. The findings illustrate the ability of the suggested MADM technique to completely present the decision data, enhance the accuracy of decision outcomes and prevent information loss.
Ultrasound guided full mechanical thrombectomy of a floating thrombus in the common femoral vein

A Floating Venous Thrombus (FVT) in the deep venous system has a high potential to cause pulmonary embolization. There are no defined criteria for treatments described in the literature, which range from anticoagulation and fibrinolytic treatments, through open or endovascular thrombectomies, to more invasive procedures such as surgical interruption with ligation of the venous system. Catheter-directed thrombolysis is effective for treatment of venous clots, but it is associated with increased risk of bleeding. Mechanical thrombectomy currently represents a valid therapeutic option without the need for lytic therapy and with excellent short and medium-term results. We herein present a technical note through an explicative case of a patient with an FVT located in the left common femoral vein who underwent to percutaneous venous mechanical thrombectomy (ClotTriever, Inari Medical, Irvine, CA, USA) under ultrasound guidance without an intravascular ultrasound check. At the end of the treatment, venography and duplex ultrasound scan showed ilio-femoral patency without residual thrombus. No further procedures were needed and the patient was discharged two days post-intervention with oral anticoagulation and compression therapy with stockings.

In a finite Coxeter group

that are full support, while simultaneously being
simple
extensions (i.e., extensions by a single reflection) of some
standard
parabolic subgroup of

in

. The enumeration is given by a product formula that depends only on the two parabolic types. Our derivation is case-free and combines a geometric interpretation of the “full support” property with a double-counting argument involving Crapo's beta invariant. As a corollary, this approach gives the first case-free proof of Chapoton's formula for the number of reflections of full support in a real reflection group

Published: December 2023

Objectives : In this study, high-pressure soil washing was performed on in-situ gas station soils for the remediation of petroleum-contaminated gas station sites.Methods : On-site gas station soils (GSS) collected from four different locations were subjected to high-pressure soil washing to analyze the amount of fine soil removal and TPH concentration after washing according to the cut-off size (0.075, 0.105 mm). In addition, the four GSS were evaluated for the relationship between the organic matter content of each soil and TPH removal efficiency. Furthermore, to evaluate the disintegration force of high-pressure soil washing technology to disperse soil aggregates, the particle size distribution of the soil before and after washing was evaluated and XRD analysis was performed.Results and Discussion : As the cut-off size increased (0.075 mm → 0.105 mm), the removal rate of fine soil in the GSS increased, and the TPH concentration tended to decrease. With respect to the TPH Soil Contamination Warning Standard for Region 2 (800 mg/kg), only the GSS 3 was in compliance with the standard (630 mg/kg). There were no significant differences in fine soil removal rates among the soils, which was expected since all the soils tested represented the same sandy loam. Washing efficiencies by soil were relatively low for soils with relatively high organic matter content. The particle size distribution showed the largest particle reduction was in the 2-0.850 mm range after remediation, while soil particles increased in the 0.105-0.075 mm and <0.075 mm range. In addition, XRD analysis showed an increase in the peak intensity of Quartz and the removal of clay mineral after washing, confirming the effective breakdown of soil aggregates and removal of fine soil by cavitation.Conclusion : If an optimal cut-off size is established, considering the soil texture and economics of the contaminated site after identifying the initial organic content level in the soil prior to washing, it is anticipated that high-pressure soil washing technology will be effectively applied for the remediation of petroleum-contaminated gas station sites.
Nitrogen Budget of South Korea from 2015 to 2019 Including Gaseous Nitrogen Oxides
Authors: Kim Hyun-Kyung , Park Seong Min , Park Jae-Woo
Published: December 2023

Objectives : The study was aimed to systematically understand the nitrogen budget from 2015 to 2019, and to determine the annual nitrogen balance in South Korea.Methods : The nitrogen budget was calculated by classifying into agricultural and livestock, city, and forest areas. The nitrogen input was estimated from deposition, biological fixation, agricultural water, inorganic chemical fertilizer, compost, feedstuff, produced crops, imported grocery, and fuel consumption. The nitrogen output was estimated by considering denitrification, volatilization, ground water runoff, land and crop absorption, sewage disposal, drainage, forest uptake, and nitrogen oxide (NOx) emissions.Results and Discussion : The annual nitrogen budget from 2015 to 2019 showed the input as 6,107,449 ton/yr, 6,144,666 ton/yr, 6,245,240 ton/yr, 6,281,552 ton/yr, 5,993,347 ton/yr and the output as 1,346,587 ton/yr, 1,369,119 ton/yr, 1,365,327 ton/yr, 1,378,940 ton/yr, 1,365,994 ton/yr, respectively. The NOx, highly contributing to change in the nitrogen budget, was caused by human activities such as vehicles, business places, and power plants. More than 32% of the total nitrogen budget was caused by NOx in every year.Conclusion : The nitrogen budget continued to increase in the 2010s because of the increase in food and fuel consumption by urbanization. However, the nitrogen budget declined in 2019 due to the effort such as emission regulations and the use of alternatives as the awareness of environmental pollution gradually increased. Therefore, the appropriate institution should be established and actively implemented to reduce the nitrogen effectively.

Published: December 2023

This study assessed the performance of single and modified algorithms based on machine learning and deep learning for wastewater treatment process. More specifically, this study adopted support vector machine (SVM), random forest (RF), and artificial neural network (ANN) for machine learning as well as long short-term memory (LSTM) for deep learning. The performance of these (single) algorithms were compared with that of modified ones processed through hyperparameter tuning, ensemble learning (only for machine learning), and multi-layer stacking (i.e., two layers of LSTM units). The daily effluent of wastewater treatment process observed between 2017 and 2022 in the Cheong-Ju National Industrial Complex was used as input to all tested algorithms, which was evaluated with respect to mean squared error. For the model performance evaluation, discharge and biochemical oxygen demand are selected as dependent variables out of nine measured parameters. Results showed that the performance of any machine learning algorithms was superior to their competitor LSTM. This is mainly attributed to a small amount of input data provided to the LSTM algorithm and unstable effluent wastewater characteristics. Meanwhile, hyperparameter tuning improved the performance of all tested algorithms. However, ensemble learning for machine learning and two-layer stacking for LSTM generally resulted in performance degradation as compared to that of single algorithms, regardless of dependent variables. Therefore, this calls for a careful design and evaluation of modified algorithms, specifically for model architecture and performance improvement processes.

Burn injuries present a global public health concern, causing around 180,000 deaths annually, with the majority occurring in low- and middle-income countries. This study, conducted at Benyamin Guluh Hospital in Kolaka, aimed to explore the relationship between burn causes and burn degrees and severity. Among 31 participants, scalding was the predominant cause (61.3%), and a significant relationship was found between causes and burn degrees (p = 0.032, r = 0.235). However, no significant relationship was observed between causes and burn severity (p = 0.524, r = 0.143). Understanding these connections can inform targeted interventions for burn patients, especially in the Southeast Sulawesi region.
