Authors: Sasmita Susi , Dewi Citra , Nasrum Muh. , Hendra Hendra , Badollahi Muh. Zainuddin
Published: April 2024

This research aims to understand the symbols and meanings of the Mematua ritual procession among the Kaili indigenous people in Siniu Sayogindano Village. This research uses an ethnographic analysis. Ethnographic analysis is an approach that begins with field facts, analyzes them based on cultural theories and relevant arguments to explore the cultural situation of the community, and ultimately yields a conclusion. The results show that the Mematua ritual procession among the Kaili indigenous people is an event rich in symbols and meanings, embodying deep cultural values and reflecting local wisdom. The eight stages of this procession, from the Polele fetching the bride to both newlyweds seeking blessings from their parents, not only represent steps in a wedding ritual but also teach the importance of harmony, respect, and commitment in marital life. Each aspect of the Mematua ritual reflects harmony among individuals, families, and the broader indigenous community. This underscores that marriage in the Kaili indigenous tradition is an event uniting two individuals and a community ritual involving respect for social and spiritual values passed down through generations. Therefore, it is recommended that the Department of Education and Culture of Parigi Moutong Regency intensify efforts to document and research the Mematua ritual procession of the Kaili indigenous people to ensure that the richness of symbols and meanings in this tradition is preserved and continues to be recognized by future generations. For the Kaili indigenous people, it is advised to continue nurturing and practicing this tradition, not only as a way to celebrate significant life moments but also as a means to strengthen community bonds and honor a rich cultural legacy. Greater involvement of the indigenous community in preparing and conducting this ritual procession can effectively preserve the social and spiritual values foundational to the Kaili tribe amidst the challenges of modernity and globalization.

Published: April 2024

Natural antioxidants, such as phenolic compounds, carotenoids, vitamins, and microelements, are predominant in fruits, vegetables, herbs, and spices. The accretion interest of consumers in utilizing natural ingredients in food products, have accelerated the appeal for functional “natural” operations. Therefore, understanding how natural antioxidants especially nano-antioxidants, and their delivery systems when used in antioxidant polymers for food packaging are extracted from natural sources, would help prevent oxidation reactions. Given the increasing role of natural antioxidants in the daily lives of today’s communities, a continuous synthesis of relevant literature is pertinent. To supplement existing information, recent advances in nano-related natural antioxidants, their extraction methods and applications in the food industry are discussed in this current work. Insightfully positioning antioxidants within the nano-delivery systems, this current work reveals the potential nanotechnology provides in enhancing the absorption of antioxidants in human metabolic systems.
Roles of nutrition in minimizing stress-related infertility: a narrative review
Authors: Sharma Luxita , Sharma Dhananjay
Published: April 2024

Infertility is a crucial and common health issue worldwide, that affects people both physiologically and psychosocially. The condition is described as the disease of the reproductive system of either male or female or both, incapability to instate a pregnancy after one year or more than twelve months of regular unprotected sexual intercourse or six months for women aged 35 years or more. Presently, the etiology of infertility is not well understood, many genetic factors, lifestyle factors, and environmental conditions such as stress work, oxidative stress, unbalanced nutrition, and unhealthy dietary patterns have been implicated to interfere with reproductive safety in both the sex. The nutritional factors are known to be amenable to normal and healthy reproductive function in both males and females. According to many studies, increased energy intake, dietary behavioral change, and low physical activity are responsible for epidemic disorders such as diabetes, heart disease, and obesity that affect reproductive health as well, and clear evidence indicates that there is a connection between inappropriate nutrition and sperm quality. Endocrinal disruption, occupational stress, and lifestyle behavior are positively linked with the pathophysiology of infecundity. Imbalance intake of both macro and micronutrients negatively affects normal reproductive function. Changes in eating behavior, and unhealthy dietary patterns such as a higher intake of food prepared with saturated and trans fats, spicy and salty foods, and a lower intake of antioxidants including fruit and vegetables are associated with reproductive life. This narrative review summarized that many studies with more consumption of fruit, vegetables, whole cereals, meat, poultry, skim milk, and seafood and less consumption of fried, spicy, salty, sugary, processed cereals and meats are linked with good sperm count.

Understanding autoimmune pancreatitis: Clinical features, management challenges, and association with malignancies
Authors: Christodoulidis Grigorios , Kouliou Marina Nektaria , Koumarelas Konstantinos Eleftherios
Published: April 2024

In this editorial we comment on the article by Jaber et al . Autoimmune pancreatitis (AIP) represents a distinct form of pancreatitis, categorized into AIP-1 and AIP-2, characterized by obstructive jaundice, lymphoplasmacytic infiltrate, and fibrosis. AIP-1, associated with elevated immunoglobulin G4 (IgG4) levels, exhibits higher relapse rates, affecting older males, while AIP-2 is less common and linked to inflammatory bowel disease. AIP is considered a manifestation of IgG4-related systemic disease, sharing characteristic histological findings. Steroids are the primary treatment, with emerging biomarkers like interferon alpha and interleukin-33. AIP poses an increased risk of various malignancies, and the association with pancreatic cancer is debated. Surgery is reserved for severe cases, necessitating careful evaluation due to diagnostic challenges. AIP patients may have concurrent PanINs but display favorable long-term outcomes compared to pancreatic cancer patients. Thorough diagnostic assessment, including biopsy and steroid response, is crucial for informed surgical decisions in AIP.
Probiotics: Shaping the gut immunological responses
Authors: Filidou Eirini , Kandilogiannakis Leonidas , Shrewsbury Anne , Kolios George , Kotzampassi Katerina
Published: April 2024

Probiotics are live microorganisms exerting beneficial effects on the host’s health when administered in adequate amounts. Among the most popular and adequately studied probiotics are bacteria from the families Lactobacillaceae , Bifidobacteriaceae and yeasts. Most of them have been shown, both in vitro and in vivo studies of intestinal inflammation models, to provide favorable results by means of improving the gut microbiota composition, promoting the wound healing process and shaping the immunological responses. Chronic intestinal conditions, such as inflammatory bowel diseases (IBD), are characterized by an imbalance in microbiota composition, with decreased diversity, and by relapsing and persisting inflammation, which may lead to mucosal damage. Although the results of the clinical studies investigating the effect of probiotics on patients with IBD are still controversial, it is without doubt that these microorganisms and their metabolites, now named postbiotics, have a positive influence on both the host’s microbiota and the immune system, and ultimately alter the topical tissue microenvironment. This influence is achieved through three axes: (1) By displacement of potential pathogens via competitive exclusion; (2) by offering protection to the host through the secretion of various defensive mediators; and (3) by supplying the host with essential nutrients. We will analyze and discuss almost all the in vitro and in vivo studies of the past 2 years dealing with the possible favorable effects of certain probiotic genus on gut immunological responses, highlighting which species are the most beneficial against intestinal inflammation.

Authors: Qian Gui-Xiang , Xu Zi-Ling , Li Yong-Hai , Lu Jian-Lin , Bu Xiang-Yi , Wei Ming-Tong , Jia Wei-Dong
Published: April 2024

BACKGROUND

The prognosis for hepatocellular carcinoma (HCC) in the presence of cirrhosis is unfavourable, primarily attributable to the high incidence of recurrence.

AIM

To develop a machine learning model for predicting early recurrence (ER) of post-hepatectomy HCC in patients with cirrhosis and to stratify patients’ overall survival (OS) based on the predicted risk of recurrence.

METHODS

In this retrospective study, 214 HCC patients with cirrhosis who underwent curative hepatectomy were examined. Radiomics feature selection was conducted using the least absolute shrinkage and selection operator and recursive feature elimination methods. Clinical-radiologic features were selected through univariate and multivariate logistic regression analyses. Five machine learning methods were used for model comparison, aiming to identify the optimal model. The model’s performance was evaluated using the receiver operating characteristic curve [area under the curve (AUC)], calibration, and decision curve analysis. Additionally, the Kaplan-Meier (K-M) curve was used to evaluate the stratification effect of the model on patient OS.

RESULTS

Within this study, the most effective predictive performance for ER of post-hepatectomy HCC in the background of cirrhosis was demonstrated by a model that integrated radiomics features and clinical-radiologic features. In the training cohort, this model attained an AUC of 0.844, while in the validation cohort, it achieved a value of 0.790. The K-M curves illustrated that the combined model not only facilitated risk stratification but also exhibited significant discriminatory ability concerning patients’ OS.

CONCLUSION

The combined model, integrating both radiomics and clinical-radiologic characteristics, exhibited excellent performance in HCC with cirrhosis. The K-M curves assessing OS revealed statistically significant differences.
Circulating tumor DNA in liquid biopsy: Current diagnostic limitation
Authors: Liu Shi-Cai
Published: April 2024

With the rapid development of science and technology, cell-free DNA (cfDNA) is rapidly becoming an important biomarker for tumor diagnosis, monitoring and prognosis, and this cfDNA-based liquid biopsy technology has great potential to become an important part of precision medicine. cfDNA is the total amount of free DNA in the systemic circulation, including DNA fragments derived from tumor cells and all other somatic cells. Tumor cells release fragments of DNA into the bloodstream, and this source of cfDNA is called circulating tumor DNA (ctDNA). cfDNA detection has become a major focus in the field of tumor research in recent years, which provides a new opportunity for non-invasive diagnosis and prognosis of cancer. In this paper, we discuss the limitations of the study on the origin and dynamics analysis of ctDNA, and how to solve these problems in the future. Although the future faces major challenges, it also contains great potential.

Die neue, derzeit im Bau befindliche rund 4,0 km lange Storstrømsbroen, die als multimodale Brücke eine zweigleisige Hochgeschwindigkeits-Eisenbahntrasse mit einer Straße auf einem gemeinsamen Überbauquerschnitt vereint, wird die dänischen Inseln Falster und Seeland verbinden und so einen integralen Bestandteil der zukünftigen festen Eisenbahnverbindung zwischen Kopenhagen und Hamburg bilden. Die Gründung der 44 Brückenpfeiler sowie des zentralen 103 m hohen Pylons der Schrägkabelbrücke erfolgt im Wesentlichen über große vorgefertigte Caissons, die als Flachgründung über mächtige Schottertragschichten auf dem Meeresboden in dem hier anstehenden, eiszeitlich vorbelasteten Geschiebemergel abgesetzt werden. Dabei kommen an einigen Achsen ergänzend auch Baugrundverbesserungen mit ´rigid inclusions´ zur Anwendung. In dem Beitrag wird über die maßgebenden geotechnischen Herausforderungen bei der Bemessung und Optimierung der hoch beanspruchten Flachgründungen in dem überkonsolidierten ´Danish Glacial Till´ berichtet. Dabei wurden über die übliche Bemessungspraxis deutlich hinausgehende Ansätze, wie die Berücksichtigung nichtlinearer globaler Gründungssteifigkeiten, dynamische hochgradig nichtlineare Analysen am Gesamtmodell und die Akzeptanz irreversibler plastischer Verzerrungen genutzt, um die unter anderem infolge von Verkehrslasten, Eisdruck und Schiffsanprall stark exzentrisch belasteten Fundamente in ihren Abmessungen nachhaltig zu optimieren.

Gesamtlärm – Wie Konflikte das Problem lösen/Total Annoyance – How conflicts can solve the problem
Authors: Hirsch K. W. , Vogelsang B. M.
Published: April 2024

Die Gesamtlärmbetrachtung gewinnt in jüngerer Zeit im Rahmen von Genehmigungsverfahren immer mehr an Bedeutung. Jedoch besteht keine Klarheit darüber, was eigentlich damit gemeint ist beziehungsweise wie der Gesamtlärm zu berechnen wäre. Solange das Lärmumfeld allein durch Anlagen bestimmt wird, die nach TA Lärm zu beurteilen sind, wird die Gesamtlärmbetrachtung durch das Konzept der Gesamtbelastung als Summe von Vor- und Zusatzbelastung im Regelfall hinreichend gestützt. Spielen aber auch Anlagen, die nicht der TA Lärm unterliegen, oder Geräuschquellenarten mit einem spezifischen Beurteilungsverfahren eine Rolle, sind andere Konzepte notwendig. Einfach Ansätze, die Beurteilungspegel addieren sind nicht zielführend. Mittels der Kenngröße ‚Konflikt‘, die die Pegeldifferenz eines Beurteilungspegels zu einem Richtwert darstellt, lässt sich eine Gesamtlärmbetrachtung auf nachvollziehbar zu ermittelnde Lärmkriterien zurückführen, die ein Maß für die Gesamtbelästigung darstellen. Dabei kann der Beurteilungspegel und der Richtwert zu einem beliebigen Beurteilungsverfahren gehören, solange der Richtwert den Übergang zwischen ‚nicht erheblichen‘ und ‚erheblicher‘ Belästigung beschreibt. Nach einer Diskussion über die Grundlagen von Beurteilungsverfahren und einer Analyse der Beurteilung nach TA Lärm werden Regeln mit Hilfe der Konflikte vorgeschlagen, die auch und gerade bei Anlagen mit unterschiedlichen Geräuschquellenarten abwägungsfrei angewendet werden können, um eine numerische Grundlage für eine „Gesamtlärmbetrachtung“ bereitzuhalten.

Abstract: A good and appropriate product quality control system can maintain product quality in accordance with the standards set by the company. Fabrics produced at PT X still has problems, namely the existence of product defects that exceed the maximum tolerance limit for defective products that have been set by the company, which is 2%. Types of fabric defects that often occur include color not ok (WTO), spot defects, crease marks and dirty color, so it is necessary to do an analysis for product quality control in each process using statistical quality control methods. ). Statistical quality control can detect the existence of special causes in variations or process errors through analysis of data from the past and the future by finding the cause of damage or product defects through existing data. Based on the results of the p control chart (p-chart) it was found that the quality of 100% viscose rayon fabric was outside the control limit, it was shown that there were still points that were outside the control limit and these points fluctuated very high and irregularly. This is an indication that the process is in an uncontrolled state or is still experiencing deviations. Furthermore, the results of the causal diagram analysis can identify the factors that cause defects in the production process, which are derived from factors of workers, production machines, work methods, and dyestuff/material. The data from the statistical quality control results can be quickly corrected so that the same mistakes do not happen again.

Evaluation of the lighting system in the science laboratory at school X in South Tangerang based on SNI 6197: 2020
Authors: Amarulloh Reza Ruhbani , Nurhuda Tiara
Published: April 2024

This study aims to determine the feasibility of a laboratory lighting system in a school in South Tangerang based on SNI 6197: 2020. The methods used include direct observation and measurement of the actual condition of the laboratory and lighting simulations for various time conditions and room occupancy. The results showed that the actual condition of laboratory lighting has not met the minimum standards set, so it is necessary to redesign the lighting system, especially in increasing the utilization of natural lighting. With an actual WWR of 2.5%, daylighting is inadequate to achieve the desired illuminance level, making a redesign of the lighting system essential. Increasing the WWR to 10% resulted in an average illuminance that met and exceeded the minimum standards during operational hours, with average illuminance values in work areas consistently higher than 500 lx. This was done with the hope of optimizing laboratory functions and creating a conducive learning environment.
The perceived importance of words in large font guides learning and selective memory
Authors: Murphy Dillon H. , Rhodes Matthew G. , Castel Alan D.
Published: April 2024

People are often presented with large amounts of information to remember, and in many cases, the font size of information may be indicative of its importance (such as headlines or warnings). In the present study, we examined how learners perceive the importance of information in different font sizes and how beliefs about font size influence selective memory. In Experiment 1, participants were presented with to-be-remembered words that were either unrelated or related to a goal (e.g., items for a camping trip) in either small or large font. Participants rated words in large font as more important to remember than words in small font when the words in a list were unrelated but not when the words were schematically related to a goal. In Experiments 2 and 3, we were interested in how learners’ belief that font size is indicative of importance translates to their ability to selectively encode and recall valuable information. Specifically, we presented participants with words in various font sizes, and larger fonts either corresponded to greater point values or smaller point values (values counted towards participants’ scores if recalled). When larger fonts corresponded with greater point values, participants were better able to selectively remember high-value words relative to low-value words. Thus, when to-be-remembered information varies in value, font size may be less diagnostic of an item’s importance (the item’s importance drives memory), and when the value of information is consistent with a learner’s belief, learners can better engage in selective memory.

Published: April 2024

In this paper, we modelled the Chinese pond mussel distribution in the European subcontinent under the recent climatic conditions and two climate change scenarios.  Using species records of Sinanodonta woodiana (Bivalvia: Unionidae) in Europe and a set of bioclimatic variables, we applied the maximum entropy approach provided by MaxEnt to build the species distribution models and investigate how each climatic variable affects the species distribution. We found that winter temperatures had the largest contribution to the species distribution in all three scenarios (recent, RCP 4.5, RCP 8.5). We applied the minimum training presence threshold, as a less stringent, and 10th percentile training presence threshold, as more stringent, to map the potential area of the species occurrence. The models show that the climatically optimal range, depicted by the stricter threshold, will be expanded eastwards under all three scenarios. At the same time, the area of minimally suitable environments, represented by the less stringent threshold, will be contracted in the future climate. The species distribution models highlight that the climatic conditions of the British Isles and the Azov-Kuban Lowland are the most suitable, among the uninvaded regions, for further S. woodiana invasion.

This case report describes a 24-year-old woman with a secundum atrial septal defect (ASD) who underwent successful percutaneous ASD closure with significant improvement in symptoms and functional capacity. The patient presented with easy fatigue and shortness of breath on exertion for 10 years. Echocardiography revealed a large secundum ASD with moderate to severe tricuspid regurgitation, mild mitral regurgitation, mild pulmonary regurgitation, and dilatation of the right atrium and ventricle. Right heart catheterization confirmed a large left-to-right shunt and pulmonary hypertension. The patient underwent ASD closure with a Figulla Flex II device, resulting in immediate improvement of hemodynamics. Follow-up at 3 and 6 months demonstrated decreased right ventricular size, improved left ventricular function, and increased exercise caapacity. This case highlights the benefits of ASD closure in improving symptoms and cardiac function, even in patients with longstanding right ventricular dilation.

The University of South Africa was the first university in Africa to offer distance education since 1946. Its success inspired other African countries like Zimbabwe and Botswana to establish Open and Distance Learning universities. In Eswatini, the Ministry of Education and Training policy of 2018 calls for the introduction of ODL in all existing and new institutions of higher learning. The policy however does not have guidelines on ODL implementation. In the interim Eswatini does not have a fully-fledged open and distance learning university. The study was conducted to explore how teacher training institutions in Eswatini implemented ODeL under the prevailing circumstances. The findings revealed that ODeL was introduced in teacher training institutions as a reactive measure to mitigate the COVID-19 lockdown that restricted students and lecturers from accessing campuses. Institutions were not ready to deliver programmes through the ODeL model. It recommended that institutions should use a blended learning approach while building capacity to gradually introduce ODeL, and train their students and staff on e-learning knowledge and skills. The Ministry of Education and Training should enact a policy with guidelines and a framework for implementing ODeL, and the government should build an open and distance learning university to align with other countries.

James Webb Space Telescope (JWST) observations have been demonstrated to be efficient in detecting multiple stellar populations in globular clusters (GCs) in the low-mass regime of M dwarfs. We present an overview, and first results, of different projects that can be explored by using the JWST observations gathered under program GO2560 for 47 Tucanae, the first program entirely devoted to the investigation of multiple populations in very-low-mass stars, which includes spectroscopic data for the faintest GC stars for which spectra are available. Our color–magnitude diagram (CMD) shows some substructures for ultracool stars, including gaps and breaks in slope. In particular, we observe both a gap and a minimum in the F322W2 luminosity function less than 1 mag apart, and discuss which it could be associated with the H-burning limit. We detect stars fainter than this minimum, very likely brown dwarfs. We corroborate the ubiquity of the multiple populations across different masses, from ∼0.1 M
⊙ up to red giants (∼0.8 M
⊙). The oxygen range inferred for the M dwarfs, both from the CMD and from the spectra of two M dwarfs associated with different populations, is similar to that observed for giants. We have not detected any difference between the fractions of stars in distinct populations across stellar masses ≳ 0.1 M
⊙. This work demonstrates the JWST's capability in uncovering multiple populations within M dwarfs and illustrates the possibility to analyze very-low-mass stars in GCs approaching the H-burning limit and the brown-dwarf sequence.

Seed germination is the most essential stage of the plant life. Prior to germination, seed dormancy provides protection to the seed against germinating under unfavorable conditions. The seeds of many plants in arid regions are particularly characterized by having a hard seed coat. Seed dormancy is essential to the survival of plants, however in some incidents such as reforestation on desert areas, it is important for ecologists to investigate methods of breaking the dormancy of seeds in order to maximize the production of plants. In this study, we tested four methods of seed pre-treatment (Mechanical scarification (MChip), chemical scarification with sulfuric acid at two exposure durations (SAcid15, SAcid30), and soaking in water for 24 h (Soak)) on 9 flowering plants (Senna italica, Sorghum sudanense, Tephrosia nubica, Senna angustifolia, Acacia tortilis, Senna occidentalis, Abutilon pannosum, Prosopis cineraria, Crotalaria persica) of the UAE. Six germination parameters (Final germination percentage (G) %, Mean germination time (MGT) day, Mean germination rate (MGR) day, Coefficient of velocity of germination (CVG) %, Mean Daily Germination Percentage (MDG) %, and Germination index (GI) day) were calculated to assess the germination. Final Germination Percentage (G) significantly improved (P < 0.005) in seven species (100% in S. italica, 98% in S. sudanense, 97% in T. nubica, 99% in S. angustifolia, 98% in A. tortilis, 99% in P. cineraria, and 93% in C. persica) with Mchip and SAcid30 (1.124% in S. italica, 28% in S. sudanense, 3% in T. nubica,82% in S. angustifolia, 96% in A. tortilis, 99% in P. cineraria, and 25% in C. persica), three species (1.562% in S. italica, 28% in S. sudanense, 3% in T. nubica, 62% in S. angustifolia, and 62% in P. cineraria) with (SAcid15), and only two species (3% in T. nubica and 5% in A. tortilis) with Soak. S. occidentalis was the only species that did not show significant changes in germination parameters after each treatment. Mechanical scarification is the safest and most affective pretreatment method according to our findings.
An assessment of factors affecting productivity and production limitations of wheat farming in Kanchanpur district of Nepal
Authors: Kafle Kamal , Joshi Pankaj Prasad
Published: April 2024

Despite possessing considerable prospective for wheat cultivation, productivity in Kanchanpur remains lower compared to that of neighbouring districts like Kailali, Banke, Kapilbastu, and Rupendehi which share similar meteorological conditions. The primary objective of this study is to investigate the influential variables affecting wheat production and to determine the associated challenges inherent in wheat cultivation within the area of the Kanchanpur district. Given the substantial prospects for wheat farming in this geographic region, the Kanchanpur district was purposively selected, and research was conducted during March and April of 2022. Through a simple random sampling technique, one hundred households of wheat farmers were systematically chosen. Primary data were collected through the utilization of pre-tested semi-structured questionnaires administered via face-to-face interviews, while secondary data were sourced from pertinent journals. The factors influencing wheat production were determined through the application of a multiple regression model. The findings of this research underscore that variables such as the quantity of applied NPK (Nitrogen, Phosphorus, and Potassium), the educational level of the household head, the extent of wheat-cultivated land with irrigation facilities, and the farmers’ years of experience in the field exerted a significant positive influence on wheat production in the study area. To identify the major constraints in wheat production, an indexing method was applied. The research identifies the unavailability of chemical fertilizer during critical growth periods, challenges arising from damage caused by wild animals and stray cattle, the lack of access to improved seeds and irrigation, susceptibility to diseases and pests, and inadequate market access as a major constraint affecting wheat production in the research area.
An assessment of Diploknema butyracea (Roxb.) H. J. Lam (Chiuri) utilization in Chepang community Chitwan district, Nepal

Chiuri (Diploknema butyracea) is a medium-sized tree indigenous to Nepal and integral to the Chepang ethnic group. The utilization of Chiuri has experienced a decline, leading to a perceptible gap between agricultural practitioners and entrepreneurial endeavors within the Chepang community. This study, conducted from January to July 2023 in the Rapti municipality of the Chitwan district, Nepal, aims to document both traditional and contemporary applications of Chiuri in the Chepang community, evaluating its market presence, economic contributions, and cultural practices. The research involved household surveys and six key informant interviews, employing structured and semi-structured questionnaires for primary data collection. The collected data underwent meticulous analysis using MS-Excel and statistical tools. Traditionally, the Chepang community employed Chiuri for diverse purposes, including the extraction of Chiuri butter, utilization of flower juice, leaf plate fabrication, liso production, and oilcake processing. However, contemporary practices have witnessed a transition towards packaged oil, various juice derivatives, and fertilizer. Historically, Chiuri butter held paramount importance as the primary source of income for the Chepang community, supplemented by revenue generated from honey, oilcake, leaf plate crafting, alcohol juice production, and liso manufacturing. Over the past two decades, a marked decline is evident, with only 36% of the population currently engaged in processing and selling Chiuri products, compared to 85% in the past. Market transactions predominantly occur in Lothar Bazaar, trailed by Bhandara and local markets, where Chiuri butter, honey, and seeds are the primary commodities. Beekeeping, honey production and butter have emerged as the predominant sources of income. Historically vital for the economic and social well-being of the Chepang community, Chiuri has seen a decline in traditional practices such as Chepuwa (Khalang) oil extraction and a diminishing prevalence of the dowry system. Adopting cost-effective treatment technology is crucial to replace traditional methods and ensure sustainable Chiuri product production.
