PREDICTION OF THE RISK OF SEVERE PERITONITIS IN ACUTE INFLAMMATORY DISEASES OF THE ABDOMINAL CAVITY
Authors: Karol I. V. , Bilyayeva O. O.
Published: January 2024

Abstract. Introduction. One of the most challenging problems of surgery is peritonitis, which can be a complication of acute inflammatory diseases of the abdominal cavity and is accompanied by high mortality. The development of prognostic models of peritonitis is a modern task of precision medicine.

Aim. To determine the risk of severe peritonitis in patients undergoing surgery for acute abdominal diseases.

Materials and methods. The study involved 139 patients who had been operated on for acute abdominal diseases (acute appendicitis and cholecystitis, perforated gastric or duodenal ulcer, etc.). Depending on the number of points on the modified APACHE II scale, patients were divided into two groups: Group 1 - 1-3 points (63 patients, 45.3%) and Group 2 - 4 or more points (76 patients, 54.7%). The rs1927911, rs2149356 and rs4986790 polymorphisms were determined by polymerase chain reaction using the Gene Amp® PCR System 7500 amplifier (Applied Biosystems, USA) and TaqMan Mutation Detection Assays Life-Technology (USA). Statistical processing of the study results was performed using the EZR v.1.54 software (Vienna, Austria).

Results. Univariate regression analysis revealed a higher (p=0.008) risk of severe peritonitis for men (OR 2.56; 95% CI 1.29-5.11) compared with women; an increase (p=0.031) in the risk of severe peritonitis with patient age (OR 1.02; 95% CI 1.00-1.05). The risk of severe peritonitis increased (p<0.05) with higher admission temperature, heart rate, international normalised ratio, and leukocytosis. A reduction (p=0.009) in the risk of severe peritonitis was found with a higher prothrombin index (OR 0.95; 95% CI 0.92-0.99). In addition, a decrease (p=0.015) in the risk of severe peritonitis was found in carriers of the G/A+A/A rs1927911 heterozygote of the TLR4 gene (OR 0.42; 95% CI 0.21-0.84) compared with carriers of the ancestral G/G genotype. The multivariate model included the rs1927911 genotype, age, sex, heart rate, and leukocytosis (AUC=0.83; 95% CI 0.75-0.89; p<0.001); the model sensitivity was 68.4% (95% CI 56.7%-78.6%), and specificity was 88.9% (95% CI 78.4%-95.4%).

Conclusion. Thus, prognostic risk factors for severe peritonitis were identified and a mathematical model for its prediction was developed using clinical, laboratory and genetic parameters.

Published: January 2024

Abstract. Aim: to assess the safety of mini-laparoscopic cholecystectomy (MLC) compared to traditional laparoscopic cholecystectomy (LC) based on a critical view of safety (CVS).

Materials and methods: an analysis of 46 video recordings of MLC surgeries and 156 LC surgeries performed for chronic calculous cholecystitis and gallbladder polyps between 2015 and 2022 was conducted, using the concept of CVS and the quality of its achievement. An analysis of anatomical variations was also performed.

Results and discussion: the average age was 38.5 years in the MLC group and 53.8 years in the LC group, with an average operation time of (59.4±2.13) minutes and (63.01±2.01) minutes, respectively. CVS was achieved in 97.8 % of cases in MLC and 93.0 % in LC. Anatomical variations were present in 31.1 % of cases in MLC and 30.1% in LC. There were no complications of MLC, conversions from MLC to LC, or open surgery.

Conclusions: The frequency of achieving CVS in MLC was higher than in LHE (97.8 % vs. 93.0 %). Anatomical variations of the biliary system should always be considered for the safe cholecystectomy. MLC is a safe technique that is not inferior to standard LCE in elective surgery in patients with a normal BMI, and at the same time has better cosmetic results.

Published: January 2024

Early identification of COVID-19 can facilitate the establishment of a swift medical response plan, thereby slowing the rapid dissemination of this deadly disease. Recent advancements in medical imaging technology, coupled with the successful application of deep learning to visual tasks, have driven numerous studies investigating early disease diagnosis through medical imaging. In particular, deep learning has been employed for COVID-19 diagnosis from CT scan images. This paper proposes an ensemble COVID detection model that integrates four models including GoogleNet, EfficientNet, Hybrid EfficientNet and DOLG, and DenseNet121. And an augmentation dataset for training/testing is utilized in this work. To comparing performance, we train four models separately with our ensemble model and evaluate their results. The results demonstrate that our ensemble model outperforms all individual models, obtaining a detection accuracy of 94 percents. Hence, our proposed ensemble model shows the potential of the ensemble method in improving the accuracy of COVID diagnosis.
Short-term Trading and Stock Mispricing
Authors:   The Korean Data Analysis Society, d d
Published: January 2024

This paper examines the influence of short-term trading on stock mispricing. Using a mispricing index proposed by Stambaugh, Yu, Yuan (2012, 2015) as a proxy for stock mispricing, This paper investigates how sensitive quarterly short-term institutional trading is to changes in the level of stock mispricing. This paper’s main finding is that trading by short-term institutions is negatively associated with the change-of-stock mispricing index, especially when stock liquidity is high. This paper supports the theoretical view of Cespa, Vives (2015), in which short-term trading can improve price informativeness when liquidity trading is persistent. Also, this research contributes to a better understanding of the interplay between short-term trading and stock mispricing, offering insights into its role in enhancing price efficiency and market dynamics.

This study’s purpose was to investigate the factors affecting well-dying of clinical nurses. Participants included 112 clinical nurses from 4 medium-sized hospitals and 2 university hospitals in Busan. Data was collected from 15 March to 10 April 2023, through structured questionnaires. The collected data was analyzed using the IBM SPSS Statistics 26.0 Program, through independent t-test, ANOVA, Pearson's correlation coefficient, and step-wised regression. As a result, the perception of well-ding in clinical nurses showed statistical differences according to gender (t=2.112, p=.037), marital status (t=2.403, p=.018), job position (F=4.806, p=.010) and type of shift (F=6.445, p=.002). The correlation between the perception of hospice and person-centered care (r=.450, p<.001), between the perception of hospice and well-dying (r=.517, p<.001), between person-centered acre and well-dying (r=.363, p<.001) was found to be positive correlation. The factors influencing well-dying were the perception of hospice (β=.40, p<.001), type of shift (β=.18, p=.038). The total explanatory power of these variables was 32.8%. Therefore, to enhance clinical nurses' well-dying, there need to be a certain curriculum including hospice and person-centered care. Through these efforts, we can expect to improve a positive attitude toward about death and can provide physical, social, mental and spiritual care to end-of-life patients.

Published: January 2024

Cluster analysis is an unsupervised learning method to find heterogeneous clusters that capture similarities among items and separate different items into different clusters. Various cluster analysis techniques have been proposed, and the k-means clustering method, which minimizes the sum of Euclidean distances between cluster centroids and individual entities, is widely recognized as a standard cluster analysis method. When data include missing values, it is challenging to conduct cluster analysis, because it is impossible to calculate distances between centroids of clusters and incomplete items, resulting in excluding classification of these items. Techniques have been suggested to handle missing values in k-means clustering, including conducting cluster analysis after imputation of missing values or cluster analysis based on available information. In this study, we explore methods to perform k-means cluster analysis on data with missing values and evaluate performance of these methods using a simulation. The results of simulation studies indicate that conducting k-means cluster analysis after imputation yields the better performance than the one based on available information. Among the various imputation methods, k-nearest neighbors imputation performed the best.
Causal Inference between social activities and sales of Venture Start-Up: Using Causal Forest
Authors:   The Korean Data Analysis Society, Chun Young Joon , Kwon Tae Yeon
Published: January 2024

The impact of corporate's social activities on sustainable management is increasing, and this is not just for large companies, but also expanding to small and medium-sized companies and venture companies. Accordingly, in this paper, the effect of the social activities of venture companies on sales was empirically analyzed through the Causal Forest method. Causal Forest is a machine learning model that allows the effect (treatment effect) of the variable of interest to be tested through causal reasoning after controlling several other characteristic variables that affect the objective variable through random forest modeling. As a result of empirical analysis using detailed survey data of venture companies from 2015 to 2020, it was confirmed that the social activities of venture companies had a significant average treatment effect (ATE) on sales. In addition, it was confirmed that the difference in the individual conditional average treatment effect (CATE) on the sales of social activities was significant depending on the size of the company's debt and the degree of investment activation. At this time, the treatment effect of companies with low total debt and low investment activation was widely distributed, which can be attributed to the characteristics of venture companies that focus on investment and technological innovation and show various corporate forms.
The Impact of Carbon Emission Trading on Industrial Production Activities in Jeonnam Region
Authors:   The Korean Data Analysis Society, Jiang Zhuhua , Park Beom Ki
Published: January 2024

When comparing South Korea's emission trading market on a global scale, such as in Europe, the United States, and China, South Korea possesses the hardware infrastructure required for the operation of an emission trading system. However, it appears to be lacking in the software aspect, including the implementation of various carbon reduction policies to complement the carbon emission trading system. The study empirically analyzes the impact of the carbon emission trading system on industries in Jeonnam. First, the carbon emission trading system does not seem to significantly constrain short-term production activities of businesses. Second, when examining the impact of carbon emission prices (KAU, EUA) on major industries in the Jeonnam region, carbon-related variables act as information intermediaries. It is evident that the chemical and steel industries in Jeonnam play the role of information recipients. Third, concerning the connectivity network with KAU as the central variable, it is apparent that the chemical and steel industries in Jeonnam receive more influence from KAU rather than influencing it. In the case of the connectivity network with EUA as the central variable, EUA plays the role of information recipients for the chemical and steel industries. This can be attributed to the participation of these industries in the European carbon emission trading market while exporting chemical and steel products to Europe, affecting EUA demand and prices. In the future, the impact of carbon emission reduction policies is likely to increase for domestic industries and companies in the Jeonnam region in the short term. To achieve regional and national carbon neutrality, policy measures tailored to the industrial structure characteristics of the Jeonnam region must be developed.

The idea behind Markov chain model and system of equations cannot be emphasized in terms of modeling physical systems like the Nigerian Current Account formation; since each finite state communicates for suitable decisions making. So this paper studied stochastic analysis of Markov chain on NCA data (2004-2022). The NCA data were transformed into 3-steps transition probability matrix solution to cover the number of independent years. From the transition matrix of stochastic analysis showed that in 2004-2012 has the highest probability of reducing in payments by 72%, the year 2005-2013 has  the highest probability of reducing by 66% and finally in 2014-2022 has the highest probability of no-change in payments of goods and services by 3.3%.   The future NCA data changes were known by introducing the concepts of percentages in each interval of years as column vectors where system of linear equations were developed and solutions were obtained to guide Nigerian economy on various levels of imports and exports of goods and services. Lastly, other statistical disparities were also considered and well discussed accordingly. These results are informative to Nigerian economy to effectively take vital decisions in their investment plans.

Pacientes geriátricos e em cuidados paliativos possuem fatores que impossibilitam a administração oral e intravenosa de medicamentos. Assim, é necessário buscar uma via alternativa. A hipodermóclise consiste na administração de fluidos e medicamentos no tecido subcutâneo, tratando-se de uma prática simples e de baixo custo. A prática foi utilizada na antiguidade, sendo abandonada devido aos relatos de eventos adversos decorrentes do uso indevido da via. Com o advento dos cuidados paliativos a técnica foi reposicionada. Apesar de suas vantagens sobre outras técnicas de administração, a prática ainda é pouco difundida no Brasil. O objetivo deste trabalho foi elaborar um protocolo de uso de antibióticos por hipodermóclise a fim de contribuir para a padronização da prática no complexo Hospital das Clínicas da Universidade Federal de Minas Gerais (HC-UFMG).

Pap smear screening test is one of the early prevention efforts to detect cervical cancer. Manual screening tests are still prone to observation errors. This study aims to create a convolutional neural network (CNN) model and support vector machine (SVM) model to identify cervical cancer through pap smear images. The data used are 4049 normal and pathological cervical cells in pap smear images sourced from SIPaKMeD, which were divided into 5 classes based on the level of cancer malignancy. The CNN model is used to extract features on the pap smear image, and SVM is used to carry out the classification. The results of this study are four cervical cancer classification models on pap smear images using Resnet50 and Resnet50V2 architecture and SVM algorithms with different scenarios on freeze and unfreeze of the convolution layer. The classification model with the best performance has an accuracy of 97.09%. CNN model with freezing the convolution layer provides much faster in the pre-trained model and the integration of this model with the SVM as the classifier results in the classification model of cervical cells in pap smear images with high accuracy.

تعد أتعاب المحاماة، التي يتَّفق عليها المحامي مع موكله، المقابل الذي يحصل عليه عن الأعمال القانونية التي يقوم بها نيابة عن موكله سواء كانت هذا الأعمال هي استشارات قانونية أو صياغة الوثائق القانونية كالعقود بمختلف أنواعها والانذارات أو تمثيل الموكل أم الجهات الادارية أو القضائية أو حتى المراجعات الادارية نيابة عن الموكل، وقد يتَّخذ هذا التمثيل صفة الخصومة أمام هيئات التحكيم، بل أكثر من هذا فإنَّ المحاكم العليا في معظم دول العالم لا تقبل نظر الطعون أمامها إلا إذا كانت موقعة من محام يتمتع بصلاحية الترافع أمام المحكمة العليا حيث تتدرج صلاحية المحامي في تلك الدول حسب تدرج المحاكم فهناك محام يظهر أمام المحاكم الابتدائية وصلاحية محام أمام محاكم الاستئناف وصلاحية محاكم أمام محكمة التمييز أو النقض، فلا يقبل من محام الظهور أمام محكمة الاستئناف ما لم يتمتع بصلاحية الظهور أمام هذه المحاكم ولا يحوز لمحام أن يوقع طعنا أو يظهر أمام محكمة النقض ما لم بتمتع بصلاحية الظهور أمام محكمة النقض وفي الحالة الأخيرة هي الصلاحية (ج) على وفق قانون المحاماة العراقي.

وأعمال المحاماة لا تعد أعمالا تبرعية، بل يتلَّقى المحامي عنها أجرًا يكون هو وسيلته الأساسية للكسب والعيش، ولهذا إذا لم يتَّفق الاتفاق بين الطرفين على مقدار أتعاب المحاماة، ولم يكن هناك اتفاق صريح على قيام المحامي بعمله مجانًا، فإنَّ المحامي يستحقُّ أتعابًا يؤخذ فيها بنظر الاعتبار الجهد الذي بذله في العمل الذي أوكل إليه ومقدار ما استفاده الموكل من عمل المحامي، وهي معايير تقريبية لا تشير إلى الأجر الدقيق الذي يستحقه المحامي وإنَّما فيها مؤشرات على مقدار ذلك الأجر.

وأجر المحامي يخضع في تقديره للقاعدة العامة في العقود وهو مبدأ حرية التعاقد، فلكلِّ محامي أن يتَّفق مع موكله على مقدار الأجر الذي يستحقه، ويلتزم الموكل بدفع هذا الأجر بالطريقة المتَّفق عليها بين الطرفين
Insight into the Formation of β Pic b through the Composition of Its Parent Protoplanetary Disk as Revealed by the β Pic Moving Group Member HD 181327

It has been suggested that β Pic b has a supersolar metallicity and subsolar C/O ratio. Assuming solar carbon and oxygen abundances for the star β Pic and therefore the planet’s parent protoplanetary disk, β Pic b’s C/O ratio suggests that it formed via core accretion between its parent protoplanetary disk’s H2O and CO2 ice lines. However, β Pic b’s high metallicity is difficult to reconcile with its mass M
p = 11.7 M
Jup. Massive stars can present peculiar photospheric abundances that are unlikely to record the abundances of their former protoplanetary disks. This issue can be overcome for early-type stars in moving groups by inferring the elemental abundances of the FGK stars in the same moving group that formed in the same molecular cloud and presumably share the same composition. We infer the photospheric abundances of the F dwarf HD 181327, a β Pic moving group member that is the best available proxy for the composition of β Pic b’s parent protoplanetary disk. In parallel, we infer updated atmospheric abundances for β Pic b. As expected for a planet of its mass formed via core-accretion beyond its parent protoplanetary disk’s H2O ice line, we find that β Pic b’s atmosphere is consistent with stellar metallicity and confirm that it has superstellar carbon and oxygen abundances with a substellar C/O ratio. We propose that the elemental abundances of FGK dwarfs in moving groups can be used as proxies for the otherwise difficult-to-infer elemental abundances of early-type and late-type members of the same moving groups.
Asteroseismology Applied to Constrain Structure Parameters of δ Scuti Stars

Published: January 2024

Asteroseismology is a powerful tool to probe stellar structure. Spaceborne instruments like CoRoT, Kepler, and TESS have observed the oscillations of numerous stars, among which δ Scutis are particularly interesting, owing to their fast rotation and complex pulsation mechanisms. In this work, we inferred model-dependent masses, metallicities, and ages of 60 δ Scuti stars from photometric, spectroscopic, and asteroseismic observations using least-squares minimization. These statistics have the potential to explain why only a tiny fraction of δ Scuti stars pulsate in a very clean manner. We find most of these stars with masses around 1.6 M
⊙ and metallicities below Z = 0.010. We observed a bimodality in age for these stars, with more than half the sample younger than 30 Myr, while the remaining ones were inferred to be older, i.e., hundreds of Myrs. This work emphasizes the importance of the large-frequency separation (Δν) in studies of δ Scutis. We also designed three machine-learning (ML) models that hold the potential for inferring these parameters at lower computational cost and much more rapidly. These models further revealed that constraining dipole modes can help in significantly improving age estimation and that radial modes succinctly encode information regarding luminosity and temperature. Using the ML models, we also gained qualitative insight into the importance of stellar observables in estimating mass, metallicity, and age. The effective temperature T
eff strongly affects the inference of all structure parameters, and the asteroseismic offset parameter ϵ plays an essential role in the inference of age.

Absolute distances from strong lensing can anchor Type Ia Supernovae (SNe Ia) at cosmological distances giving a model-independent inference of the Hubble constant (H
0). Future observations could provide strong lensing time-delay distances with source redshifts up to z ≃ 4, which are much higher than the maximum redshift of SNe Ia observed so far. In order to make full use of time-delay distances measured at higher redshifts, we use quasars as a complementary cosmic probe to measure cosmological distances at redshifts beyond those of SNe Ia and provide a model-independent method to determine H
0. In this work, we demonstrate a model-independent, joint constraint of SNe Ia, quasars, and time-delay distances from strong lensed quasars. We first generate mock data sets of SNe Ia, quasar, and time-delay distances based on a fiducial cosmological model. Then, we calibrate the quasar parameters model independently using Gaussian process (GP) regression with mock SNe Ia data. Finally, we determine the value of H
0 model-independently using GP regression from mock quasars and time-delay distances from strong lensing systems. As a comparison, we also show the H
0 results obtained from mock SNe Ia in combination with time-delay lensing systems whose redshifts overlap with SNe Ia. Our results show that quasars at higher redshifts show great potential to extend the redshift coverage of SNe Ia and thus enable the full use of strong lens time-delay distance measurements from ongoing cosmic surveys and improve the accuracy of the estimation of H
0 from 2.1% to 1.3% when the uncertainties of the time-delay distances are 5% of the distance values.

Published: January 2024

Interplanetary Type III bursts, generated by relativistic electron beams at solar flare reconnection sites, are explored through an investigation of 152 instances observed by the Solar Terrestrial Relations Observatory mission. This study reveals that the absolute values of the wavevector deviations from the Sun–spacecraft line are statistically 3.72 and 2.10 larger than predicted by the density model, assuming fundamental and harmonic emission, respectively. Through Monte Carlo simulations, we examine the impact of scattering by density inhomogeneities on the apparent locations of radio emissions in the interplanetary medium. The findings indicate that relative density fluctuations of 0.40 can account for the observed angular shift, a conclusion supported by the multiple flux-tube solar wind model, which confirms the presence of such magnitude of relative perpendicular density fluctuations in the solar wind. We propose a wavevector correction that incorporates this effect to enhance the triangulation of interplanetary Type III bursts, demonstrating that radio triangulation, with this correction, can reliably track electron beams in the interplanetary medium.

The advent of autonomous vehicles (AVs) poses challenges to parking guidance in mixed driving scenarios involving human-driven vehicles (HVs) and AVs. This study introduced a dynamic and coordinated strategy (DCS) to optimize parking space allocation and path guidance within a mixed driving parking lot, aiming to enhance parking-cruising efficiency. DCS considers the distinctive characteristics of HVs and AVs and dynamically formulates parking guiding schemes based on real-time conditions. The strategy encompasses four main steps: Triggering scheme formulation, identifying preoccupied parking spaces, updating the parking lot traffic network and optimizing the vehicle-path-space matching scheme. A programming model was established to minimize the total remaining cruising time, and iterative optimization was conducted with vehicle loading test based on timing. To elevate computational efficiency, the concept of parking-cruising path tree (PCPT) and its updating method were introduced based on the dynamic shortest path tree algorithm. Comparative analysis of cases and simulations demonstrated the efficacy of DCS in mitigating parking-cruising duration of different types of vehicles and minimizing forced delays arising from lane blocking. Notably, the optimization effect is particularly significant for vehicles with extended cruising durations or in parking lots with low AV penetration rates and high saturation, with an achievable optimization rate reaching up to 18%. This study addressed challenges related to drivers' noncompliance with guidance and lane blocking, thereby improving overall operational efficiency in mixed driving parking lots.

This paper presents the results of an experimental study of the interaction of a candidate sacrificial material (SM) for a light water reactor melt trap with corium at the Lava-B test-bench. The candidate sacrificial material is a combination of aluminum oxide and a lead layer. The idea of using such a combination of SM is based on the fact that when the lead layer interacts with corium, there will be an increase in the intensity of heat removal from the corium, as well as the chemical interaction between the corium and SM due to the high heat-conducting properties of lead. This approach will improve the efficiency of corium localization in the melt trap compared to the current set of sacrificial material. Experiments have shown active melting and boiling of lead during its interaction with corium. This is confirmed both by the readings of thermocouples and by the X-ray diffraction phase analysis of the deposit material formed on the walls of the melt receiver (MR) of the Lava-B bench, sampled after the experiment. The experiment results show that the lead layer reduces the rate of increase in the temperature of the corium and increases the rate of erosion of the ceramic part of the SM. With these circumstances, it is possible to conclude that the use of aluminum oxide with a lead layer is promising in practice.
$ L_2/L_1 $ induced norm and Hankel norm analysis in sampled-data systems
Authors: Hagiwara Tomomichi , Sugiyama Masaki
Published: January 2024

This paper is concerned with the $ L_2/L_1 $ induced and Hankel norms of sampled-data systems. In defining the Hankel norm, the $ h $-periodicity of the input-output relation of sampled-data systems is taken into account, where $ h $ denotes the sampling period; past and future are separated by the instant $ \Theta\in[0, h) $, and the norm of the operator describing the mapping from the past input in $ L_1 $ to the future output in $ L_2 $ is called the quasi $ L_2/L_1 $ Hankel norm at $ \Theta $. The $ L_2/L_1 $ Hankel norm is defined as the supremum over $ \Theta\in[0, h) $ of this norm, and if it is actually attained as the maximum, then a maximum-attaining $ \Theta $ is called a critical instant. This paper gives characterization for the $ L_2/L_1 $ induced norm, the quasi $ L_2/L_1 $ Hankel norm at $ \Theta $ and the $ L_2/L_1 $ Hankel norm, and it shows that the first and the third ones coincide with each other and a critical instant always exists. The matrix-valued function $ H(\varphi) $ on $ [0, h) $ plays a key role in the sense that the induced/Hankel norm can be obtained and a critical instant can be detected only through $ H(\varphi) $, even though $ \varphi $ is a variable that is totally irrelevant to $ \Theta $. The relevance of the induced/Hankel norm to the $ H_2 $ norm of sampled-data systems is also discussed.

Published: January 2024

The automated boat’s deckhouse is made of deforested wood and glass fiber, harming producers, fishermen, and marine life. In context, researchers are attempting to make composites from waste and replace synthetic materials with natural composites. In the present work, a Carbon/Mg/Si/polyester hybrid composite is developed as a potential replacement for wood in marine deckhouse construction. Impact, tensile, flexural, Rockwell and Brinell hardness were tested using ASTM standards, as well as weight absorption in fresh and seawater. Scanning electron microscopy (SEM), microanalysis (EDAX), Fourier-transform infrared spectroscopy (FTIR) and Raman Spectroscopy techniques were used to identify microstructure, elements, and functional groups. Thermogravimetric analysis and differential scanning calorimetry (DSC) are used to determine the thermal stability and heat intake/rejection of the hybrid composite. Novel hybrid composites with Mg-Si fillers improve the mechanical strength, adhesion, corrosion resistance, and deckhouse life span in marine environments.

This study explores multi-actors' perspectives on Environment, Social, and Governance (ESG) reporting in Sri Lankan listed companies. While most studies have explored the perceptions of managerial and non-managerial stakeholders regarding ESG reporting in developed countries, there is a scarcity of research in developing countries. Only a few studies have yet addressed the phenomenon of ESG reporting in Sri Lanka by analysing the multi-actors’ perspectives. On the other hand, most previous studies have primarily investigated internal organizational factors that influence ESG reporting using a quantitative method. In this study, ESG reporting was assessed through the perspectives of multi-actors. Qualitative methodology is used to analyze the participants’ perspectives following an interpretivist approach. Using semi-structured in-depth interviews, exploratory data was collected related to the research topic. Participants for the sample were selected based on engagement with ESG activities, knowledge, and personal experience. Interviewees participated in face-to-face and online interviews via Zoom. Thematic analysis was performed to identify the common themes from the respondents' explanations. Awareness, reporting guidelines, stakeholders’ demands, top management commitment, capturing information, and education are the major themes identified in ESG reporting in listed entities. The study contributes to understanding the phenomenon of ESG reporting and it presents findings that may be useful for theory and practice. Finally, the study provides empirical evidence for regulatory authorities and policymakers on the actions and methods for developing ESG reporting in listed companies in Sri Lanka.
