Authors: Siddiqui Eram Jamal , Azad Iqbal , Khan Dr. Abdul Rahman , Khan Dr. Tahmeena
Published: September 2024

Objective: Thiosemicarbazones are Schiff based ligands of significant biological importance and their biological relevance has been studied for a considerable amount of time period. When the thiosemicarbazones bind with metal ions, they have shown an array of potential anticancer, antimicrobial and antioxidant activities etc. They have also found numerous applications in Analytical Chemistry. This present review summarizes some of the medicinal benefits of thiosemicarbazone based complexes especially with transition metals.
Data Sources: The studies cited in the present review were sourced from journals, books and conference proceedings preferentially written and published in English. Literature from the past 15 years or so has been included in the article. Papers indexed in known databases such as PUBMED, SCOPUS, INDEX COPERNICUS, CHEMICAL AND BIOLOGICAL ABSTRACTS, MEDLINE, EMBASE, EBSCO, DOAJ, and THOMSON REUTERS have been reviewed and included.
Summary of the contents of the article: The study unravels the mechanistic action of these compounds on in vitro living beings viz. cell culture as well as animal models. An elaborate review of the available literature on thiosemicarbazones has shown that the modifications in the ligand moiety leads to enhancement in its activity and some of the best structural alterations have been cited in the review. Some of the potential future applications and uses of the complexes have also been discussed. Structure optimization of the compounds may result in path breaking finding of potential anticancer and antimicrobial drugs.
Conclusion: Latest advances in medicinal inorganic chemistry have given considerable importance to the development of metal based drugs with thiosemicabazones. The presence of metal ion in the drug moiety usually mitigates the ill effects of the compounds, this may lead to the production of new metal based drugs. The key factors identified for their action has been the inhibition of RR, topo II and the production of ROS, but identification of other probable targets need to be explored.

Authors: Kandpal Vandita , Kumar Dharmendra , Bisht Rekha
Published: September 2024

Analysis of blood parameters is relevant to risk evaluation of alternations of the haematological system in humans and animals. Haematological parameters have been associated with health indices and are of diagnostic significance in routine clinical evaluation of the state of health of any individual. Present study was carried out to ascertain the antioxidant properties of vitamin E on haematological parameters caused by hexavalent chromium - Cr(VI) in laboratory chicks. Developing chicks (Croiler, body weight 100±20 gm) were used as experimental animals. Blood samples were collected from wing veins of chicks and analyzed after experiment. The haematological profile revealed a significant (p<0.05) reduction of Total Red Blood Cell count (RBC), total White Blood Cell count (WBC), Haemoglobin concentration (Hb), Packed cell volume (PCV) and Mean corpuscular hemoglobin concentration (MCHC) in toxin group compared to control group. However, the group of chicks treated with chromium and vitamin E alternatively, recorded significant increase in all these blood parameters indicating the protection offered by vitamin E as an ameliorating antioxidant against chromium toxicity.
Keywords: Haematological parameters, hexavalent chromium [Cr(VI)], vitamin E, antioxidant.

Published: September 2024

Medicinal Plants have proven potential of treating and preventing various disorders and illness from the ancient time. Many Phytopharmaceuticals companies are emerging as a result of its popularity in both the developed as well as developing countries. Newer approaches are developed to protect the plant source and to enhance its productivity in terms of phytochemicals so that the demand and supply can be balanced.  Costus igneus, a newer plant to India is gaining its popularity for its use as ornamental plant in southern part of the country to Diabetes treatment herbal remedy. Flavonoid diglycosides and sapogenins are mostly responsible for its anti-diabetic activity. Due to over exploitation of plant some alternative methods has to be developed in order to protect the plant from its natural habitat. Elicitors are the compounds that stimulating plant defence pathways and the secondary metabolites are released due to defence responses which are triggered and activated by elicitors. The present study was focused on the application of Salicylic acid (SA) as an elicitor in different concentration (0.50 mg/l, 0.100 mg/l, 0.150 mg/l), which was sprayed on the plants of Costus igneus grown using complete block design in controlled growth conditions provided in polyhouse and the quantitative estimation for phytochemicals was done. The results suggest that SA enhances the quantity of desired phyto pharmaceuticals, which also plays as essential role in plant defensive pathways.
Keywords: Medicinal plants, phyto-pharmaceuticals, Costus igneus, Elicitors, Salicylic acid (SA), plant defence mechanism.
Plasmapheresis in Management of Oral Autoimmune Disorders
Authors: Gupta Kanupriya
Published: September 2024

Systemic autoimmune diseases based on an immune pathogenesis produce autoantibodies and circulating immune complexes, which cause inflammation in the tissues of various organs. In most cases, these diseases have a bad prognosis without treatment. Autoimmune disorders are a group of poorly understood diseases in which the body fails to distinguish between self and non- self which could result in damage to the self. Oral mucous membrane may be affected by a variety of autoimmune mucocutaneous diseases such as pemphigus, bullous pemphigoid, mucous membrane pemphigoid, lichen planus, erythema multiforme, Steven Johnson syndrome, epidermolysis bullosa, linear IgA disease etc. These diseases (commonest being pemphigus) cannot be controlled in some cases, even with very high doses of systemic corticosteroids and immunosuppressive agents. In such cases plasmapheresis is one of the most effective therapeutic methods to deplete sera of immunoglobulin, including pathogenic autoantibodies. The aim of this review is to describe plasmapheresis as an adjunct therapy for oral autoimmune disorders.

Authors: Kondrotienė Edita , Bakanauskas Arvydas Petras , Jezukevičienė Edita
Published: September 2024

Health behaviour research is mainly based on the evaluation of the consequences of the behaviour. However, observing the worsening state of public health naturally raises questions about the causes of these trends. There are many factors influencing consumer health behaviour (legal, fiscal, demographic, political, etc.). It is agreed, that the consumer alone can hardly influence all of these mentioned factors (de Vries et al., 2018; Hilz et al., 2019). However, there are social cognitive psychological constructs (e.g., consumer attitudes), that can be partially or fully controlled or managed by the individual. In this article, the cognitive factors that influence consumer health behaviour are evaluated (pharmacy business context). The problem arises, what is the impact of cognitive factors on consumer health behaviour? The quantitative empirical research approach was chosen to reflect the attitudes of the Lithuanian population about health, research sample — 1,000 respondents. The interview was based on the computer-assisted web interview (CAWI). Results suggest, that the information from internet portals, has the most statistically significant impact on the formation of attitudes towards health. A similar tendency is reflected in health behaviour. The results of the study have practical value for pharmacy business companies and medical service companies.

J-spaces and C-normal spaces: An algebraic perspective
Authors: Mthethwa Simo , Taherifar Ali
Published: September 2024

In this article, algebraic characterisations of J-spaces and C-normal spaces
are exhibited. The concept of a Z-connected ideal in C(X) is presented and
characterised using certain connected subsets of X. We define the class of
JC-spaces and characterise its members via Z-connected ideals. Two more
classes of ideals in C(X), namely the coz-free and F-free ideals, are
instituted. These types of ideals are used to establish conditions under
which a given space is a strong J-space. We introduce the notion of a
J-lattice and show that the lattice, CL(X), of closed subsets of X is a
J-lattice if and only if X is a J-space. A pointfree topology exposition of
J-lattices is also presented, with more attention to complete Boolean
algebras.

Interpolation formulas for 1-harmonic functions on the unit circle
Authors: Djukic D.Lj. , Mutavdzic N.M. , Mutavdzic-Djukic R.M.
Published: September 2024

Ageneralization of the deeply investigated harmonic functions, known as
?-harmonic functions, have recently gained considerable attention. Similarly
to the harmonic functions, an ?-harmonic function u on the unit disc D is
uniquely determined by its values on the boundary of the disc ?D. In fact,
for any z ? D, the value of u(z) can be given as a contour integral over
?D with a modified Poisson kernel. However, this integral can be difficult to
evaluate, or the values on the boundary are known only empirically. In such
cases, approximating u(z) with an interpolatory formula, as a weighted sum
of values of u at n nodes on ?D, can be an attractive alternative. The nodes
and weights are to be chosen so that the degree d of exactness of the
formula is maximized. In other words, the formula should be exact for all
basis functions for ?-harmonic functions of degree up to d, with d as large
as possible. In the case of harmonic functions, it is known that there is an
interpolation formula of degree of exactness as large as d = n ? 1. The
objective of this paper are formulas of this type for ?-harmonic functions.
We will prove that, given n, in this case the degree of exactness cannot be
n ? 1, but there is a unique interpolation formula of degree n ? 2. Finally,
we will prove convergence of such formulas to u(z) as n ? ?.
Geometric realizations of homotopic paths over curved surfaces
Authors: Peters James , Alfano Roberto , Smith Peter , Tozzi Arturo , Vergilie Tane
Published: September 2024

This paper introduces geometric realizations of homotopic paths over
simply-connected surfaces with non-zero curvature as a means of comparing
and measuring paths between antipodes with either a Feynman path integral or
Woodhouse contour integral, resulting in a number of extensions of the
Borsuk Ulam Theorem. All realizations of homotopic paths reside on a
Riemannian surface S, which is simplyconnected and has non-zero curvature at
every point in S. A fundamental result in this paper is that for any pair of
antipodal surface points, a path can be found that begins and ends at the
antipodal points. The realization of homotopic paths as arcs on a Riemannian
surface leads to applications in Mathematical Physics in terms of Feynman
path integrals on trajectory-of-particle curves and Woodhouse countour
integrals for antipodal vectors on twistor curves. Another fundamental
result in this paper is that the Feynman trajectory of a particle is a
homotopic path geometrically realizable as a Lefschetz arc.

Published: September 2024

In this emulated comparative effectiveness target trial of glucagon-like peptide 1 (GLP-1) receptor agonist, sodium–glucose cotransporter 2 (SGLT2) inhibitor, dipeptidyl peptidase 4 (DPP-4) inhibitor, and sulfonylurea therapy among adults with type 2 diabetes at moderate cardiovascular disease risk, sulfonylurea use was associated with a significantly higher risk of hypoglycemia requiring emergency department or hospital care than treatment with DPP-4 inhibitors, GLP-1 receptor agonists, or SGLT2 inhibitors. This consideration can guide the choice of glucose-lowering therapy in this highly prevalent patient population, in whom avoidance of hypoglycemia is important, yet among whom the risk of severe hypoglycemia has not been examined previously.

Communicating Neuroanatomical Fibers in Health and Diseases
Authors: AT Wirtu , SA Geneti
Published: September 2024

Background: Combining neuroanatomical fiber information with other types of neuroimaging and genetic data can lead to a more comprehensive understanding of brain function and pathology. Variations in the branching patterns of the brachial plexus and the division of the sciatic nerve into the tibial and common fibular nerves has been documented in numerous studies, although not extensively in Ethiopia. The brachial plexus is formed by the ventral roots of spinal nerves from C5 to T1. Meanwhile, the sciatic nerve, which originates from the sacral plexus divides into the tibial and common fibular nerves at various points along its pathway. Given the significant implications of neural variations for enhancing medico legal practices, understanding these variations is crucial for making accurate diagnosis. Consequently, study examined different neuroantomical variants in Ethiopia. Objectives: To examine variations in the neural system connection and their clinical implications in the Ethiopian population and provide mechanistic insights into how different brain regions communicate and disruptions in these communications can lead to cognitive and behavioral symptoms. Methods and Materials: This research was carried out in a randomly selected medical institutions between January 2015 and February 2016. Preserved and carefully maintained human bodies were dissected by medical students, adhering to the protocols outlined in Grant’s Dissection Principles and Cunningham’s Manual of Practical Anatomy. The dissections took place in anatomy laboratory, with a specific focus on detecting any anatomical variations, particularly in the neural system of the human body. Results: In this study, we observed communication between the musculocutaneous nerve and the median nerve occurred in 6.3% of the sampled cases. Moreover, communication between the radial nerve and the ulnar nerve was found in 2.1% of the cases. Furthermore, variations in the pelvic division of the sciatic nerve were noted in 6.3% of the sampled cases from Ethiopia. Conclusion: We discovered a nerve responsible for communication within a specific part of the human body. Recognizing such communicating nerve fibers and their pathways is essential for clinicians to effectively diagnose sensorimotor symptoms. This understanding is also vital for neurologists, surgeons, and orthopedists in handling cases of nerve entrapment syndromes, carrying out post-traumatic assessments and undertaking exploratory procedures.

Published: September 2024

A field study was conducted at the Agricultural Farm of Visva-Bharati University, Sriniketan, West Bengal, during August, 2021 to January, 2022 and August, 2022 to January, 2023 to evaluate the effects of different nutrient sources on Brahmi’s growth and profitability. Seven treatments were tested: T1 (NPK @ 50:25:25), T2 (farmyard manure @ FYM 10 t ha-1), T3 (vermicompost @ 5 t ha-1), T4 (FYM @ 10 t ha-1+ seaweed extract @ 3 ml l-1), T5 (vermicompost @ 5 t ha-1+seaweed extract @ 3 ml l-1), T6 (FYM @ 5 t ha-1+vermicompost @ 2.5 t ha-1), and T7 (control with no amendments). Growth parameters such as Leaf area index (LAI), crop growth rate (CGR), and relative growth rate (RGR) were recorded. Pooled data revealed that T6 (FYM+vermicompost) resulted in the highest LAI (1.536), CGR (1.462 g m-² day-1), and RGR (0.04338 g g-1 day-1), indicating its superior performance in promoting Brahmi’s growth. T6 also achieved the highest economic returns, with gross returns of ` 2,36,728 ha-1 and a benefit-cost ratio of 2.88, making it the most profitable treatment. Treatments T3 (vermicompost) and T5 (vermicompost+seaweed extract) also performed well, particularly during early growth stages, though they were outperformed by T6 over the entire growth cycle. T1 (NPK) and T2 (FYM) showed moderate growth and economic returns, while T7 (control) recorded the lowest performance in both growth indices and profitability. These findings underscore the effectiveness of organic amendments, particularly the combination of FYM and vermicompost, in enhancing both the growth and economic viability of Brahmi cultivation.

EFFECTIVENESS ENHANCEMENT OF TRAFFIC CAMERAS BASED ON VEHICLES' AVERAGE SPEED CALCULATION
Authors:   Lviv Polytechnic National University, Urikova O. , Morhoiev K. , Chornyi D.
Published: September 2024

The analysis of calculating the vehicle speed between two automatic speed cameras within the framework of traffic violation detection demonstrates that using the average speed metric enhances speed limit compliance accuracy. This method reduces the possibility of evading responsibility for violations through temporary speed reduction before cameras. These systems employ usage of existing road cameras infrastructure to determine the minimal travel path of vehicle passing two cameras placed at a certain distance apart to measure the average speed of travel. Technical aspects of implementing the proposed system include utilizing cloud computing for data processing and storage, which reduces infrastructure costs. The system employs the possibility of usage of machine learning algorithms to predict travel time between cameras, considering various factors such as road conditions and speed limits. This approach ensures high calculation accuracy and reduces the number of false violation alerts. To further reduce the possibility of false violations, it is suggested to only use speed limitations based on the traffic signs on the road intervals of the calculated minimal path between two cameras that the vehicle has passed. Implementing the system requires the development of new software for data analysis and integration with existing traffic control systems. This includes designing algorithms to determine the minimum required travel time between cameras and calculating the average speed based on these data. Additionally, methods must be developed to detect and handle exceptions, such as road stops, or route changes, which can affect calculation accuracy. The feasibility of practical implementation of the system was investigated based on the existing infrastructure of traffic cameras in the city of Lviv. Possible minimal routes between cameras were analyzed and compared to the avarage passing speed of vehicles of different categories. The modulated results indicate that such a system would be an effective addition to the traffic control system, while requiring relatively low financial and engineering efforts.
STUDY OF THE INTELLIGENT MONITORING ALGORITHM OF QOS IN THE MASS SERVICE SYSTEMS
Authors:   Lviv Polytechnic National University, Senyk A. , Pyrih Y. , Shpur O.
Published: September 2024

The main algorithms for monitoring the quality of traffic in mass service systems (MSS) were examined in the paper, which is aimed at ensuring the stable and efficient functioning of various types of systems, such as telecommunication networks, Internet services, transport systems, etc. The main aspects of monitoring, such as the assessment of throughput, delays, and packet loss, which affect the quality of user data processing (QoS), were analyzed. The features of various approaches to determining the quality of service were determined, depending on the specifics of the work of the MMS. Monitoring the quality of service is a necessary component of managing complex systems, which allows to ensure the quality of service for users at the appropriate level. The use of various monitoring methods, both active and passive, allows to effectively control the quality of service, which contributes to the effective operation of network services. One of the effective tools for active QoS monitoring is the measurement of quality parameters by generating test packets followed by an analysis of their passage through the network. The TWAMP (Two-Way Active Measurement Protocol) algorithm was investigated in the paper, which allows for more accurate measurement of packet delays and losses in mass service systems. A modified QoS monitoring algorithm based on TWAMP was proposed, which combines a hybrid approach, adaptive tuning, intelligent anomaly detection, and prediction to ensure more efficient and accurate network monitoring. An experimental study was conducted, the results of which demonstrate that the proposed algorithm improves the quality of user service, increasing the accuracy of detecting anomalies in the operation of the MMS. Also, the modified algorithm ensured a lower probability of failures in the operation of mass service systems, thus increasing their overall productivity. Based on the conducted research, conclusions were drawn about the advantages of the proposed TWAMP-based monitoring algorithm for solving the problems of identifying anomalies in the operation of the MMS, reducing the probability of failures and failures in their functioning. It was determined that the proposed approach is relevant for use in modern information and communication systems of various types to improve the quality of user service. The modified algorithm can be used in MSS to improve the level of QoS.
APPLYING A FORMALIZED LOGICAL-PROBABILISTIC METHOD FOR DETERMINING THE SURVIVABILITY INDICATORS OF MESH NETWORKS
Authors:   Lviv Polytechnic National University, Ozirkovskyy L. , Volochiy B. , Pryymak N. , Zhuk Yu.
Published: September 2024

Using the example of an LORA MESH network, the capabilities of the logic-probabilistic trajectory modeling method for determining the survivability indicators of mission-critical systems with a mesh network structure are presented. The proposed method is formalized, and based on it, software can be implemented that allows the designer to obtain quantitative values of survivability indicators at the system engineering design stage, when the system has not yet been built in hardware, through modeling. The analysis of known methods for calculating pairwise connectivity indices shows that the use of certain organized intermediate data structures can enhance the computational efficiency of algorithms. In the correlation method, such structures are the sets of paths for the i-th iteration. In the decomposition method, relative to the key element with indexed masking of elements in the set of simple paths, these structures include an indexed array of network elements, which determines their ordering by the chosen criterion, a vector of masking levels for elements in the set of simple paths, and a stack of probabilities for incomplete paths. Therefore, the question arises about the possibility of constructing and applying other auxiliary structures and investigating the efficiency of corresponding algorithms. During the conducted research, the idea emerged to use a "spanning tree" of simple paths as such an auxiliary structure, by means of which it is possible to manage the passage of "probability packets". Methods for evaluating survivability with a grid structure of communication networks are characterized by high computational complexity. Such computational complexity hinders the multivariate analysis of design decisions. The formalization of the probabilistic packet switching method has allowed reducing computational complexity for the user (enabled the implementation of this method in software, as most calculations are performed repeatedly automatically; moreover, when changing the network configuration, the function for calculating connection pairs is formed with less time expenditure). This will allow for multivariate analysis of design decisions, improve the efficiency of system design, and significantly reduce time costs.
EVALUATION OF FREQUENCY-PHASE DISTORTIONS IN OPTICAL TELECOMMUNICATIONS USING OFDM
Authors:   Khmelnytskyi National University, Boiko J. , Eromenko O. , Pyatin I.
Published: September 2024

The article proposes a method for monitoring the peak-to-average power ratio (PAPR), and also discusses the results of assessing the sensitivity of optical-OFDM systems to phase-frequency distortions. The results of a study of the noise immunity of an optical-OFDM system for frequency shift relative to the spacing of optical subcarriers are presented. A description of the factors causing interference and frequency-phase distortions caused by chromatic dispersion (CD) and polarization mode dispersion (PMD) on the performance of optical multiplexing systems with orthogonal frequency division is carried out. Monitoring the PAPR in OFDM systems is relevant, in particular, in the context of fiber optic communication problems that are caused by the nonlinearity of the optical fiber. It is shown that when directly deploying optical networks, the presence of frequency distortions and sensitivity to phase noise are the two main disadvantages of OFDM. Both frequency distortion and phase noise lead to interchannel interference (ICI). Due to the relatively large symbol length compared to a single carrier, OFDM is susceptible to both frequency distortion and phase noise. An additional cumulative distribution function is used for a visual description of PARP. The effect of the oversampling coefficient on the PARP value is determined. It is proposed to use the oversampled signal to obtain a more accurate PARP value. The results of the study show that the effect of phase noise on a signal in optical OFDM channels is due to the existing long symbol period compared to signal transmission on a single carrier. In addition, with an increase in the modulation order, optical OFDM becomes more sensitive to phase noise, which encourages an increase in the signal-to-noise ratio to counteract this. The results of the research showed that for coherent OFDM optical systems, the line width of the optical quantum generator is a critical parameter, especially when switching to high-order modulation. The paper discusses a diagram describing the process of convergence of radio and optical technologies in the context of the use of OFDM modulation. This technique allows for the correct choice of channel multiplexing strategy in optical OFDM telecommunications with multi-position signals.

The global ecological crisis has impacted the Belt and Road Initiative (BRI) region, and due to the diverse geographical characteristics, the ecological problems in countries along the Belt and Road vary. Overcoming these environmental and ecological challenges is essential for advancing and genuinely implementing green development, and has become a practical necessity for building a “Green Belt and Road.” China, the creator of the Green “Belt and Road Initiative”, actively aligns with international environmental protection standards and plays a leading role in global ecological conservation efforts. China vigorously promotes the development of key policy documents for the Green Belt and Road, providing institutional support for the initiative’s environmentally friendly construction and development. Under comprehensive theoretical planning, various green practices have been implemented, including thematic in-depth research on the Green “Belt and Road” and the “2030 Agenda for Sustainable Development,” the establishment of the “International Green Development Coalition” along the Belt and Road, the implementation of overseas investment and green finance, and the proposal of the “Ten, Hundred, Thousand” initiative for South-South Cooperation on Climate Change. These green practices clearly indicate China’s commitment to building ecological civilization and its relentless efforts toward advancing the construction of a global ecological community with shared-benefits.

Last year we celebrated the 35th anniversary of the parliamentary elections which brought Poland's independence and allowed us to decide about our future. In every area of our lives, including science, this anniversary encouraged reflection on how we managed to use the 35 years of freedom. Thus, in this article, I briefly characterize the current state of science in Poland. Then I try to show major results of 35-year endless reforms of the science system in our country. Interestingly, so far, these reforms have practically omitted the Polish Academy of Sciences. Therefore, I also discuss the recently prepared draft law that is supposed to give a new shape to this leading national scientific institution.

Balinese gamelan as a product and heritage of Balinese culture has been faced with a new reality, that digital technology has taken some of the spirit behind the reality of Balinese gamelan. The phenomenon of digital gamelan is not something new. But for Balinese gamelan today, it is surprising. This problem shows that there are certain efforts in the development of Balinese art. This means that this problem is also generated by the influence of modern lifestyles, namely efficiency, which is expected to overcome other problems such as the difficulty of practicing time or gathering everyone to produce a gamelan music work. Therefore, the demands of those who expect gamelan music, for example, to accompany a dance, are considered to be able to shorten work time, while the use of digital technology can cut production costs. Thus, it is difficult to say whether digital gamelan produces a work of art in the same way as gamelan itself when played by several people. However, the meaning of Balinese gamelan has certainly shifted in the digital simulation phenomenon.

This research seeks to critically examine the commodification of traditional Balinese wedding ceremonies that occur at Taman Prakerti Bhuana, which offers Balinese wedding services in a more attractive and prestigious package. The study aims to understand how sacred cultural practices, rich in spiritual meaning, are transformed into commercial products focused on consumer satisfaction and economic gain. The issues will be addressed by answering the following research questions: (1) What is the form of commodification of traditional Balinese wedding ceremonies at Taman Prakerti Bhuana, (2) Why does the commodification of traditional Balinese wedding ceremonies occur at Taman Prakerti Bhuana, and (3) What are the implications of the commodification of traditional Balinese wedding ceremonies at Taman Prakerti Bhuana. These issues are analyzed using the theories of religious commodification and Bourdieu's theory of practice, employing qualitative research methods. Data collection techniques include literature study, observation, and interviews, followed by interpretative analysis. The research findings indicate that this phenomenon leads to the degradation of traditional values such as "menyama braya," a concept of togetherness and mutual cooperation in Balinese society. The commodification of these ceremonies also impacts the social dynamics of the local community, reducing active community participation and eroding the spirit of mutual cooperation. Ultimately, this study highlights the challenges faced in preserving Balinese culture, where traditional rituals that undergo changes to meet market demands risk losing their authenticity and original meaning.

Background: Several studies show differences in the nutritional status of children attending public and private schools. The Covid-19 pandemic, which has a global impact on various sectors of life, indirectly affects the nutritional status of children. During the pandemic, children stayed at home more and tended not to do strenuous activities such as exercising or going to the playground. This research aims to assess the nutritional status of children attending public and private elementary schools after the Covid-19 pandemic.Method: This research is an analytical observational study using a cross-sectional design. The research was conducted in the Academic Center room at Udayana University Hospital in July 2022. This research involved a number of elementary school students from three elementary schools in the Jimbaran, Badung, Bali area. Inclusion criteria were elementary school children aged 10-13 years with exclusion criteria including children who did not receive permission to participate in research activities from their parents after explaining post-explanatory consent (PSP). Nutritional status is assessed using anthropometric standards from WHO and Waterlow, where nutritional status will be divided into Mild PEM, Moderate PEM, and Heavy PEM, Overweight, Obese, Superobese and Normal. All data were processed and analyzed statistically using the SPSS version 21 program which was displayed in the form of proportion (percentage), number, mean (standard deviation), and median (range, minimum-maximum). Comparison of nutritional status using Chi-Square analysisResults: There were 189 children in this study with a median age of 11 years (range 11-13 years). There is no difference in the nutritional status of children attending private elementary schools and public elementary schools after the Covid-19 pandemic. There was 1 child (0.5%) with severe protein energy malnutrition (PEM), 50 children (26.5%) with mild PEM, and 67 children with normal or good condition (35.4%). Conclusion: This research shows that there is no significant difference in nutritional status between children attending public and private elementary schools after the Covid-19 pandemic. 35.4% of children had good or normal nutritional status.Key words: public elementary school, private elementary school, nutritional status, covid-19
