Authors: Kougioumtzis Ioannis E , Chloros George D , Bakhshayesh Peyman
Published: September 2023

The combination of plate and intramedullary nailing has been established as the treatment of proximal tibial fractures. Nevertheless, at the distal end of the tibia, the application of the plate-assisted intramedullary nailing is rarely applied as a therapeutic technique. This technical note demonstrates the use of the reduction plating technique for nail insertion as the management of distal tibia fractures.
Keywords: Tibial Fracture; Closed Fracture; Fracture Fixation; Internal Fixation; Intramedullary Nailing.

Published: September 2023

Background: The Integrated Child Development Services (ICDS) scheme is a community-based program in India for the betterment of health and nutrition of children aged 0-6, pregnant and lactating mothers, and women aged 15-44 years. This study aimed to investigate the pattern of the utilization of services and the level of satisfaction of mothers regarding the services provided to their children in a block of West Bengal, India.
Methods: This descriptive cross-sectional study was conducted from August 2016 to November 2018, and simple random sampling was used to select ICDS centres. The centres’ were evaluated for determining the rate of utilization of the services. For evaluating satisfaction, a face and content-validated, pre-tested questionnaire was used. The first part of questionnaire was for collecting the socio-demographic profile of mothers. The second part was concerned about determining satisfaction regarding various services provided by centers to children below 6 years of age on a 5-point Likert scale. About 10% of children enrolled in each ICDS centre were selected, and their mothers were surveyed for satisfaction regarding supplementary nutrition services, informal education, immunization, and other health-related services and infrastructures. The data were expressed in number and percentages and the test of association between categorical variables was done using a chi-square test. The GraphPad Prism 6.01 (GraphPad Software, USA) was used for statistical test.
Results: Among the surveyed 62 ICDS centres, service utilization rates were 98.04% for immunization, 90.56% for supplementary nutrition, 82.52% for informal education, 40.27% for health check-ups, and 13.32% for referral services regarding different health problems. A total of 89.63% of the mothers were satisfied with the supplementary nutrition, 83.46% with immunization and health-related services, 77.42% with informal education, and 56.5% with infrastructures.
Conclusion: Using supplementary nutrition and informal education exceeded expectations, but immunization, other health-related services, and referral services need improvement to achieve the program's goal. ICDS center infrastructure needs improvement, and a holistic approach is necessary to meet the satisfaction of mothers regarding different services.

Authors: Bahrami Mohammad Amin , Jambarsang Sara , Ranjbar Mohammad , Montazeralfaraj Razieh , Rabani Atiye
Published: September 2023

Background: Individualized care is a concept that describes personal characteristics of patients in clinical conditions, their personal life situation, and their preferences in order to promote participation in decision-making. The purpose of this study was to validate the Persian version of the Suhanen et al.'s (2005) individualized care scale.
Methods: This cross-sectional study was conducted in 2019. Initially, the individualized care scale of Suhanen et al (2005) was translated in forward-backward way with 19 items and on a 5-point Likert scale (1 = completely disagree, 2 = disagree, 3 = no opinion, 4 = agree, 5 = completely agree). Content and face validity were then assessed using the opinions of 10 health management professionals (majors of health care management, health policy and health economics) Internal reliability of the questionnaire was assessed using the opinions of 20 patients admitted to gynecology, internal medicine and surgery wards of Yazd 3 teaching hospitals, and Cronbach's alpha coefficient (0.93) was calculated using SPSS 20 software.
Results: The results of content validity calculation showed that all items of the current questionnaire had acceptable Content Validity Ratio, and the Content Validity Index was 0.73 for this questionnaire. Face validity analysis also demonstrated that all experts approved the questionnaire items. Cronbach's alpha coefficient for the whole questionnaire was 0.93, and for "clinical status", "personal life situation" and "decision-making control over care," was 0.90, 0.87 and 0.90 respectively; the values were acceptable, and the reliability of the questionnaire was confirmed; none of the items were removed.
Conclusion: The questionnaire can be used as a credible and valuable tool for assessing individualized patient care.
The Interactive Effect of Good Governance and Oil Rent on Life Expectancy in Iran
Authors: Mansour Sahebe Mohamadian , Golkhandan Abolghasem
Published: September 2023

Background: Oil revenues, as an important part of the government's revenues in Iran's oil-dependent economy, play an important role in providing public sector expenditures, including the health sector and consequently have an impact on health outputs. On the other hand, the way of using and managing oil revenues is an important factor in the way of this effect. Therefore, the main purpose of this study was to investigate the interactive effect of good governance and oil rent on life expectancy in Iran.
Methods: The present descriptive-analytical study investigated the short-term and long-term equilibrium relationship between health output index, per capita income, oil rent, good governance index, and the cross (interactive) effect of good governance and oil rent from 1985 to 2020 using the time series data of Iran. The data used were collected from World Bank global development indicators database and international country risk guide. Also, model estimation was conducted using and autoregressive distributed lag and data analysis was performed using Eviews 10 software.
Results: The results show that in the short and long term, the increase in oil rent improves the health output index in the country. One percent increase in the share of oil rent from gross domestic product (GDP), in the long and short term, increases the life expectancy in the country by about 0.101 and 0.668 percent, respectively. However, the interactive effect of oil rent and good governance index in the short and long term is negative and significant with coefficients of - 0.084 and - 0.515; which shows that oil rent leads to a decrease in life expectancy by weakening good governance indicators.
Conclusions: Based on the findings of this study, it can be said that oil rent is inherently useful in promoting health in the country; but its improper use and management causes the health sector to not benefit from it and even become a loss.

Authors: Meskarpour_Amiri Mohammad , Jafari Amir
Published: September 2023

Background: The proper selection of financial indicators can assist in making optimal decisions in financial resource management and enhancing the efficiency of universities. Therefore, the aim of this research was to identify the required financial indicators for designing and developing a comprehensive financial management system of the selected medical university.
Methods: The present cross-sectional study was conducted in 2022 in 2 stages. In the first stage, the required financial indicators for designing and developing a comprehensive financial management system were identified through a literature review and financial theoretical foundations. In the second stage, the content validity of the indicators for application in the financial system was assessed through a survey of experts using the Waltz and Bausell and Lawshe questionnaires. The research population consisted of a group of university experts from Tehran medical sciences universities with a minimum of 10 years of work experience and at least a bachelor's degree, and a proper recognition of relevant affairs in the field of financial management, auditing, and accounting. Among them, 21 individuals were purposefully selected. Data analysis was performed using MaxQDA 12 and Excel software.
Results: A total of 17 financial indicators were identified and classified into 6 main areas, including "liquidity," "profitability," "revenue generation," "capital structure," "investment," and "financial risk." The highest level of Content Validity Ratio pertained to the "profit" and "human capital value added" indicators (CVR= 90 %), and the highest level of Content Validity Index was also related to the "labor cost” and “human capital value added" (CVI = 100 %).
Conclusion: University managers and policymakers can have a desired evaluation of the university financial performance using the proposed indicators in this research. Therefore, it is suggested to design software for recording indicators based on this model (17 indicators in 6 main areas) and establish a database for the assessment of the university financial performance and the mechanism for collecting and analyzing information based on it.
Локальная интроспекция: заметки о поэтике жанра
Authors: Щукин Василий
Published: September 2023

В статье рассматриваются некоторые черты поэтики жанра интроспекции (заглядывания вовнутрь), связанной с мифопоэтическим оформлением локуса домашнего окна. Окно является границей, отделяющей внутреннее, обжитое пространство дома от более хаотичного и неизведанного, а потому потенциально опасного внешнего пространства. В художественной литературе встречаются две основные разновидности интроспекции: статическая и, реже, динамическая. Каждая из них позволяет построить разные варианты поэтических ситуаций. Некоторые из них, почерпнутые из произведений М. Ю. Лермонтова, Н. В. Гоголя, И. С. Тургенева, А. Терца и других авторов, приведены в качестве иллюстраций таких ситуаций.

Zdrowa rodzina adopcyjna – to znaczy jaka?
Authors: Posłuszna-Owczarz Maria
Published: September 2023

On the one hand, adoptive family is an alternative for married couples who are not able to have progeny, on the other hand, it is an alternative for social orphans to have proper family. So as well as fulfilling a lot of functions of biological families, adoptive families also compensate for social orphanhood. Only a healthy family can face such a responsible task. According to modern psychology, pedagogics and sociology, family is a small social group, a community which follows certain rules. A healthy family is a functional family, which makes every one of its members happy and gives them possibility to fulfill their needs. There are all sorts of difficulties, failures and arguments in such a family, however, mutual relationships and the potential of its particular members motivates to look for satisfying solutions for every one of them. So, what should characterize a healthy adoptive family, what inner-family factors and outer conditions might disturb its functioning. These questions need to be tried and answered already in the diagnosing and preparation period for the adoptive parents candidates. It is also important to prepare a child (depending on age), because both the child and its future parents bring to the newly created adoptive family their genetic heritage, health condition, previous experiences and life plans, hopes, value, skills, mutual relations, ways to communicate and deal with difficulties and so on. Final court decision on adoption should not be the end, but the beginning of post-adoptive work with the new family, in order to strengthen its proper and healthy functioning.

Statusy tożsamości osobowej u młodzieży zamieszkującej Polskę oraz mieszkającej na Litwie
Authors: Rydz Sylwia , Głód Anita
Published: September 2023

Tożsamość osobowa jest jednym z podstawowych aspektów jednostki, który daje
jej poczucie ciągłości w czasie, spójności i odrębności od innych. Koncepcja tożsamości wywodzi
się od Erika Eriksona, następnie została wzbogacona przez Jamesa Marcię oraz Wima Meeusa,
gdzie zostały wyodrębnione cztery statusy tożsamości jako cztery sposoby radzenia sobie z problemami
tożsamościowymi. Poczucie tożsamości kształtuje się przez całe życie jednostki, jednakże na
okres dorastania przypada kryzys tożsamości. To wówczas człowiek stawia sobie podstawowe pytania
związane z poczuciem Ja: kim jestem, do czego dążę, co jest dla mnie ważne? To gdzie mieszkamy
– czy w ojczyźnie, czy poza nią – wydaje się mieć znaczenie dla kształtowania się tożsamości
osobowej.
Podjęto próbę porównania statusów tożsamości młodych Polaków mieszkających w Polsce
oraz młodych Polaków mieszkających na Litwie. W badaniu zastosowano odrębny pomiar czterech
statusów tożsamości dla czterech sfer ważnych z punktu widzenia poszukiwań i wyborów tożsamościowych:
sfera relacji z rodzicami, rówieśnikami, szkoła, ideologia. Uzyskano szereg interesujących
różnic.

Authors: Kaed Ezzadeen , Saany Syarilla Iryani A. , Alhazmi Abdulsalam K. , Saif Jalal
Published: September 2023

In the field of online learning, the topic of engagement has drawn a lot of attention. According to research, when students engage in their own learning, they experience a variety of benefits, including greater motivation and achievement. Several metrics for gauging student engagement have been proposed in previous studies. Few, however, have been created to assess involvement in online learning contexts. The goal of this study is to create an instrument for measuring student involvement in online learning settings. A critical synthesis of the literature was carried out by categorizing and then critically reviewing the literature in order to construct and integrate the variables that could aid in successful learning outcomes, leading to the development of a framework that can guide in achieving student engagement. This study confirms earlier findings while also directing the development of a student engagement framework for online learning systems. The suggested model would bring value to literature by enhancing and improving understanding of the elements influencing student engagement in an online learning environment, resulting in active student learning.

The purpose of this study is to determine the intrinsic value of shares of companies engaged in the food and staples retail sub-sector which in this case is represented by PT. Sumber Alfaria Trijaya, Tbk. (AMRT), PT. Diamond Food Indonesia, Tbk. (DMND), PT.  Midi Utama Indonesia, Tbk. (MIDI), PT. Enseval Putera Megatrading, Tbk. (EPMT), and PT. Millenium Pharmacon Internatioanl, Tbk. (SDPC) listed on the Indonesia Stock Exchange (IDX). This research uses historical data for 2018-2022 which will be used as the basis for projections for 2023-2027. The results showed that by using the Discounted Cash Flow (DCF) method, specifically the Free Cash Flow to Firm (FCFF) approach, under an optimistic scenario, the intrinsic values of AMRT, SDPC, and DMND were undervalued. EPMT and MIDI stocks are overvalued. In the moderate scenario, the intrinsic values of AMRT, MIDI, EPMT, and DMND are overvalued, while SDPC is undervalued. Calculations on a pessimistic scenario, all companies studied are overvalued. In this study, the valuation of stocks was also conducted using the Relative Valuation (RV) method with the Price to Earnings Ratio (PER) and Price to Book Value (PBV) approaches. In an optimistic scenario, the stocks of AMRT, MIDI, and SDPC are considered expensive, while EPMT and DMND are seen cheap. In a moderat scenario, the stocks AMRT, EPMT, and SDPC are considered undervalued, while MIDI and DMND are seen expensive. In a pessimistic scenario, it is observed that AMRT, EPMT, and SDPC are undervalued, whereas MIDI and DMND are considered overvalued. This research aims to provide an objective assessment of the company, which investors can use to consider investments and by companies to enhance corporate value.
Fine Structure of Solar Metric Radio bursts: ARTEMIS-IV/JLS and NRH Observations
Authors: Alissandrakis Costas , Hillaris Alexander E. , Bouratzis Costas , Armatas Spyros
Published: September 2023

Radio bursts provide important diagnostics of energetic phenomena of the Sun. In particular, bursts in decimetric and metric wavelengths probe the physical conditions and the energy release processes in the low corona as well as their association with heliospheric phenomena. The advent of spectral radio data with high time and high frequency resolution has provided a wealth of information on phenomena of short duration and narrow bandwidth. Of particular value are spectral data combined with imaging observations at specific frequencies. In this work we briefly review the results of a series of observations comprised from high-sensitivity, low-noise dynamic spectra obtained with the acousto-optic analyzer (SAO) of the ARTEMIS-IV/JLS solar radiospectrograph, in conjunction with high time-resolution images from the Nançay Radioheliograph (NRH). Our studies include fine structures embedded in type IV burst continua (mostly narrow-band "spikes" and intermediate drift "fiber" bursts) and spike-like structures detected near the front of type-II bursts. The implications of the observational results to theoretical models are discussed.
Derivation Of KCl from Potassium Feldspar via Varied Salts
Authors: Türk Tülay , Kangal Murat Olgaç
Published: September 2023

Feldspar which is one of the main inputs of the ceramic and glass industry has widespread resources in Turkey and holds an outstanding role in exportation. In addition to this, potassium feldspars are one of the suitable resources for the production of potash which is a vital component for agriculture industry. The chlorination technique was used to produce potassium chloride (KCl) from potassium feldspar ore in Kırşehir-Buzlukdağı region. The process of potassium chloride production was carried out with calcination process to decompose potassium feldspar and form potassium chloride while using different kinds of salts such as CaCl2, NaCl, and CaSO4 followed by water leaching process. The recovery from feldspar with 7.21% K2O content was obtained with the 1:1.25:1.5 ratio of Feldspar:CaSO4:NaCl at 1000 °C for 60 minutes followed by leaching. 96.08 % potassium dissolution was achieved.
Immunotherapy of Multiple Myeloma: Current Status as Prologue to the Future
Authors: Abramson Hanley N.
Published: September 2023

The landscape of therapeutic measures to treat multiple myeloma has undergone a seismic shift since the dawn of the current century. This has been driven largely by the introduction of new classes of small molecules, such as proteasome blockers (e.g., bortezomib) and immunomodulators (e.g., lenalidomide), as well as by immunotherapeutic agents starting with the anti-CD38 monoclonal antibody daratumumab in 2015. Recently, other immunotherapies have been added to the armamentarium of drugs available to fight this malignancy. These include the bispecifics teclistamab, talquetamab, and elranatamab, and the chimeric antigen receptor (CAR) T-cell products idecabtagene vicleucel (ide-cel) and ciltacabtagene autoleucel (cilta-cel). While the accumulated benefits of these newer agents have resulted in a more than doubling of the disease’s five-year survival rate to nearly 60% and improved quality of life, the disease remains incurable, as patients become refractory to the drugs and experience relapse. This review covers the current scope of anti-myeloma immunotherapeutic agents, both those in clinical use and in development. Included in the discussion are additional monoclonal antibodies (mAbs), antibody-drug conjugates (ADCs), bi- and multi-targeted mAbs, and CAR T-cells and emerging natural killer (NK) cells, including products intended for “off-the-shelf” (allogeneic) applications. Emphasis is placed on the benefits of each along with the challenges that need to be surmounted if MM is to be cured.

Published: September 2023

The coronavirus disease 2019 (COVID-19) pandemic clearly has had a great influence on the lifestyle of the population, especially on patients with type 2 diabetes mellitus. During the COVID-19 outbreak, many countries/regions implemented social isolation measures, leading to an increase in negative behaviors and impairing the capability of diabetic patients to resist the COVID-19, ultimately causing a severe prognosis. Moreover, multiple studies have emphasized the significance of physical exercise in the management of type 2 diabetic patients infected with COVID-19 as the epidemic progressed. In our study, we selected research focusing on COVID-19-infected diabetic patients from Dec 1, 2019 to Aug 9, 2023 and sought to investigate the impact of type 2 diabetes on the immune function, inflammation factor levels, lung injury and mental disorders of patients, as well as to assess the risk of novel coronavirus pneumonia in these patients. And we also summarized the effects of high-intensity, moderate-intensity and low-intensity exercise on novel coronavirus pneumonia infection in type 2 diabetic patients and the mechanisms of their effects. Finally, diabetic patients with COVID-19 are suggested to perform low-intensity exercise to facilitate their recovery. Our study offers guidance for a proper understanding of the dangers of diabetes and the use of appropriate measures to reduce the risk of novel coronavirus pneumonia infections in type 2 diabetic patients.

Plant-based therapeutics and herbal medicine have played a vital role in the development of several anti-cancerous agents, and has been used to reduce the severe side effects of chemotherapy as well. Since the anti-lung cancer properties of the plant Medicago. orbicularis are not explored yet, we identified its phytochemical composition and investigated the anti-oxidant, anti-hemolytic, and anti-cancerous properties of extracts of this plant in A549 human lung adenocarcinoma cells. Results show that all parts of M. orbicularis (stems, leaves, and fruits) exhibit remarkable anti-oxidant and hemolytic activities. In addition, all extracts showed a dose-dependent anti-cancerous cytotoxic activity against A549 cells; with fruit extracts being the most potent. This cytotoxic effect could be related, at least partly, to the induction of apoptosis, where M. orbicularis fruit extracts activated Caspase-3 and PARPP-1, and reduced the ratio of anti-apoptotic BCL-2/ pro-apoptotic BAX, thereby promoting cellular death. Furthermore, the use of M. orbicularis, in combination with a conventional chemotherapeutic agent, cisplatin, was assessed. Indeed, combination of cisplatin and M. orbicularis fruit extracts was more cytotoxic and induced more aggregation of A549 cells than either treatment alone. GC-MS analysis and total polyphenol and flavonoid content determination indicated that M. orbicularis is rich in compounds that have anti-cancerous effects. M. orbicularis may be a potential source of anti-cancerous agents to manage progression of lung cancer and its resistance to therapy.

Pulmonary infections with Mycobacterium avium occur in susceptible individuals following exposure to the bacterium in the environment, where it often persists in biofilms. Many methods have been used to generate biofilms of M. avium, and it is unknown whether different approaches generate similar structures and cell phenotypes. To make a parallel comparison of in vitro biofilm ultrastructure, extracellular matrix (ECM) composition, and drug susceptibility of biofilm resident bacteria, we used two published methods to generate M. avium biofilms: four week incubation in M63 medium or 24 hour exposure to dithiothreitol (DTT). Scanning electron microscopy revealed differences in biofilm ultrastructure between the two methods, including variation in appearance of ECM materials and morphology of resident cells, while light microscopy and staining with calcofluor white indicated that both biofilms contained polysaccharides characteristic of cellulose. Measuring susceptibility of biofilms to degradation by enzymes suggested differences in structurally important ECM molecules, with DTT biofilms having important protein and, to a lesser extent, cellulose components, and M63 biofilms having moderate protein, cellulose, and DNA components. Both biofilms conferred resistance to the bactericidal effects of amikacin and clarithromycin, with resident cells being killed at >10-fold lower rates than planktonic cells at almost all concentrations. Though these comparisons indicate differences in biofilm responses by M. avium under differing conditions, they also suggest common features of biofilm formation including cellulose production and antimicrobial resistance.

Low 25 OH vitamin D (25(OH)D) in preterm infants is a risk factor of bronchopulmonary dysplasia (BPD), but increased supplementation failed to demonstrate beneficial effect on BPD. In neonatal animal models, deficiency and excessive vitamin D exposure have been associated with increased mortality and lung histological alterations evocative of BPD. Our hypothesis is that 25(OH)D levels ≥ 120nmol/L is also a risk factor for BPD or death. This retrospective single-center cohort study included all infants born <31 weeks gestational age without major malformation with at least a determination of 25(OH)D <36 weeks corrected age and no determination <50 nmol/L. Routine 25(OH)D determination was performed at 1 month and monthly thereafter. A total of 175 infants were included. Infants with BPD or who died had a significantly lower term and weight, but a similar frequency of 25(OH)D ≥120nmol/L (50.5% vs 43.9%, p=0.53). The logistic regression identified weight (OR 0.997, 95%CI [0.995-0.998]) and term (OR 0.737, 95%CI [0.551-0.975]) as significantly associated with BPD or death; the occurrence of excessive 25(OH)D was not significantly associated (OR 1.029, 95%CI [0.503-2.093]). The present study did not demonstrate any significant association between excessive 25(OH)D after one month of age and BPD or death.

Cardiac resynchronization therapy (CRT) via biventricular pacing (BiVP-CRT) is considered a mainstay treatment for symptomatic heart failure patients with reduced ejection fraction and wide QRS. However, up to one third of patients receiving BiVP-CRT are considered non-responders to the therapy. Multiples strategies have been proposed to maximize the percentage of CRT responders including two new physiological pacing modalities that have emerged during the lasts years: His bundle pacing (HBP) and left bundle branch area pacing (LBBAP). Both pacing techniques aim at restoring the normal electrical activation of the ventricles through the native conduction system in opposition to the cell-to-cell activation of conventional right ventricular myocardial pacing. Conduction system pacing (CSP), including both HBP and LBBAP appears to be a promising pacing modality for delivering CRT and has proven to be safe and feasible in this particular setting. This article will review the current state of the art of CSP-based CRT, its limitations and future directions.

Published: September 2023

Healthcare workers have atypical working schedule and are exposed to experienced stress that led to poor sleep health and frequent mental complaints, particularly since the Covid-19 crisis. We conducted a cross-sectional study to determine the prevalence of poor sleep hygiene and mental complaints and their associations among healthcare workers. Usual sleep-wake timings were ex-plored during workdays and free days and used to compute sleep duration, sleep efficiency and social jetlag. Insomnia, sleepiness, anxiety and depressive symptoms, and fatigue were calculated using validated scales. A total of 1,562 participants were included (80.5% of women and mean age of 40.0). Among them, 25.9% slept less than 6 hours, 24.3% had a poor sleep efficiency, and 11.5% reported a social jetlag. A total of 33.9% of participants reported insomnia, 45.1% reported EDS, 13.1% reported fatigue, 16.5% reported depression and 35.7% reported anxiety. After ad-justment, sleep duration and sleep efficiency were associated with mental complaints. Social jetlag was associated with significant insomnia but not with anxiety or depression symptoms. Healthcare workers have a high prevalence of poor sleep hygiene and mental complaints. The promotion of sleep health through behavioral sleep strategies should be encouraged to ensure good health for these professionals.

The Pesut Mahakam (Orcaella brevirostris) is an East Kalimantan animal in critical condition and on the verge of extinction. One of the causes of the extinction of the Mahakam dolphins is the toxic effects of environmental pollution. In this study, an analysis of the discrete predator-prey model using Euler's forward difference between the Pesut Mahakam (Orcaella brevirostris) and its prey was investigated. Dynamic analysis includes determining the equilibrium point, stability analysis of the equilibrium point, and numerical simulation. The value of the Mahakam dolphin growth rate parameter (predator) is obtained by adjusting the curve based on data in the field. Numerical simulations were carried out to describe the results of the analysis. Changes in the value of the toxic effect rate parameter affects the number of Mahakam dolphins and their prey.

The ever-changing economy requires companies to anticipate future conditions in order to avoid financial distress, a continuous decline in financial conditions. The research focused on comparing Altman and Ohlson’s financial ratio in classifying financial distress on Property and Real Estate companies using the Feedforward Neural Network. The data used is the financial report data of 19 Property and Real Estate companies listed on the Indonesian Stock Exchange in 2016-2022, with the initial status of financial conditions based on earnings per share. (EPS). The study also used the Synthetic Minority Oversampling Technique (SMOTE) method to address class imbalances.  The best financial ratio is selected based on accuracy values and Area Under Curve (AUC). Altman’s financial ratio with the FFNN model architecture (5-2-1) with a balance of 60:40 yields an accuracy of 84.62% and an AUC of 0.8325. The Ohlson Financial ratio with the 60:40 data balancing process and the FFNN model architecture (9-4-1) yields an accuracy of 93.27% and an AUC of 0.9045. Thus, in predicting financial distress in companies in the Property and Real Estate sector, Ohlson’s financial ratio with the predictor variables Corporate Size (SIZE), Total Liabilities to Total Assets (TLTA), Working Capital to Total Acts (WCTA), Current Liability to Current Asset (CLCA), OENEG, Net Income to total assets (NITA), Cash Flows Operating to Total Responsibilities (CFOTL), Net Revenue (INTWO), and Net Incoming Change (CHIN) yielded the best results. This best ratio can be used as a consideration in using alternative financial ratio to classify financial distress.

Published: September 2023

This research discusses the SISiR model (Susceptible Infected Sick Recovered) considering individual immune parameters and lockdown parameters. The consideration of these parameters aims to determine whether immunity and lockdown have an impact on the spread of COVID-19. The model's stability is analyzed around the equilibrium point to understand the dynamics of COVID-19 spread in a population. Furthermore, the parameter R0 is determined to indicate whether COVID-19 disappears or remains in the population. From numerical simulations with spesific parameter values, it is concluded that COVID-19 continues to spread in the population with an R0 = of 4.4486. The addition and reduction of immune and lockdown parameters affect the spread of COVID-19.
