Authors: Sarpova М. V. , Vaneeva Е. V. , Diakonov D. A. , Rosin V. A. , Samarina S. V.
Published: April 2024

The p14ARF-Hdm2-p53 signaling pathway targets tumor growth suppression, inhibits clonal proliferation, and maintains genome stability. It is inactivated in most human malignancies. The p14ARF protein is one of the main participants in the cascade. The aim of the study was to determine the prognostic value of the number of p14ARF-expressing tumor cells in biopsies of patients with diffuse large B cell lymphoma (DLBCL). Material and methods. The formalin-fixed paraffin embedded samples of tumor tissue of 104 patients with newly diagnosed DLBCL were included to the study. The relative number of cells expressing p14ARF was determined by immunohistochemical and morphometric methods. Differences in the content of p14ARF-positive tumor cells between groups of patients divided according to clinical and laboratory parameters were determined using the Mann–Whitney U test. Prediction of an unfavorable response to therapy was carried out using binary logistic regression with calculation of the odds ratio and 95 % confidence interval; variables were selected using Wald backward elimination method. The risk of an event occurring was calculated using Cox regression analysis. Results. The content of p14ARF-positive cells is higher in tumor biopsies of patients with high and high-intermediate risk according to the international prognostic index than in patients with low and lowintermediate risk. A relationship between an increase in the number of p14ARF-positive tumor cells, the absence of a complete response to first-line R-CHOP therapy, and an increased risk of death in patients with DLBCL has been established. Conclusions. The studied marker p14ARF can be used as an additional morphological predictor of the unfavorable course of DLBCL.

Published: April 2024

A significant contribution to the preservation and improvement of the population health is made by a healthy lifestyle, one of the components of which is rational nutrition. Considering severe stress experienced by students due to the changed social environment, the study of nutritional characteristics and the role of behavioral factors in eating behavior among medical students remains an extremely topical issue of modern preventive medicine. Material and methods. As a result of a cross-sectional study, 197 students of the Saratov Medical University were interviewed, 100 (51 %) of them were russian students, 97 (49 %) were citizens of Central African countries. The method of 24-hour reproduction of daily diet, program complex “Individual diet 5.0 professional version”, questionnaire were used. Results and discussions. The study showed an imbalance in macro- and micronutrients intake of the daily food ration, a violation in the diet, insufficient consumption of vegetables and fruits, rare hot meals, dissatisfaction with the organization of meals in student canteens, frequent use of fast food by students regardless of their country of origin. The relationship of physical activity and smoking with the diet and the frequency of consumption of vegetables and fruits, low awareness of unbalanced nutrition as a risk factor for the development of alimentary-dependent diseases have been established. Conclusions. The nutritional behavior of russian and foreign students of Saratov Medical University does not meet all the principles of healthy eating recommended by WHO. Thus, it is necessary to improve the organization of catering in student canteens, taking into account the taste preferences of foreign students, the introduction of educational activities and healthy nutrition programs with the involvement of the students themselves in their preparation. The analysis of actual nutrition is a very important task, as it allows assessing the current socio-economic situation, as well as the effectiveness of educational programs in the framework of national projects on a healthy lifestyle and proper nutrition.

Published: April 2024

Prevention of circulatory system diseases (CSDs), preservation of the health of the working population is a priority task of the Russian Federation healthcare, in the solution of which it is of interest to study the causal relationships of the influence of production factors on the development of CSDs in workers of various professional groups. The purpose of this study was to assess the prevalence and occupational causality of diseases of the circulatory system in the main professional groups of bearing production workers. Material and methods. The occupational risk of developing CSDs in workers of the main professional groups in the bearing production was assessed based on the hygienic classification of production factors and chronic non-infectious morbidity according to medical examinations using the methodology for assessing occupational health risk. Results and discussion. It has been established that bearing production workers in the course of labor activity are exposed to the complex effects of harmful (class 3.1–3.4) factors of the working environment of various nature, which determine the a priori occupational health risk in categories from low to very high. The level of CSD prevalence was 446.4‰, while arterial hypertension was the most frequently established nosologic form (80.66 %). A high degree of causal relationships of arterial hypertension with the work was established for adjusters and machine operators (RR = 2.44; etiologic fraction (EF) 58.98 %; CI = 1.335–4.450), turners (RR = 2.32; EF = 56.93 %; CI = 1.184–4.451), grinders (RR = 2.31; EF = 56.63 %; CI = 1.189–4.469), hot-spot workers (RR = 2.16; EF = 53.64 %; CI = 1.193–3.901), which indicates professional conditioning. Conclusions. The complex impact of production factors contributes to the development of CSDs among workers in the production of bearings, which is confirmed by a high degree of causal relationship between arterial hypertension and work.

Image classification using deep and classical machine learning models on small datasets: a complete comparative
Authors: Rubio-Manzano Clemente
Published: April 2024

One of the most important challenges in the Machine and Deep Learning areas today is to build good models using small datasets, because sometimes it is not possible to have large ones. Several techniques have been proposed in the literature to address this challenge. This paper aims at studying the different available Deep Learning techniques and performing a thorough experimentation to analyze which technique or combination thereof improves the performance and effectiveness of the models. A complete comparison with classical Machine Learning techniques was carried out, to contrast the results obtained using both techniques when working with small datasets. Thirteen algorithms were implemented and trained using three different small datasets (MNIST, Fashion MNIST, and CIFAR-10). Each experiment was evaluated using a well-established set of metrics (Accuracy, Precision, Recall, F1, and the Matthews correlation coefficient). The experimentation allowed concluding that it is possible to find a technique or combination of them to mitigate a lack of data, but this depends on the nature of the dataset, theamount of data, and the metrics used to evaluate them.

Published: April 2024

The growing number of the elderly and their potential use of technological products requires understanding the interaction between these users and technology to develop appropriate products that include them. Accordingly, this article focuses on studying the interaction between older people and digital games to provide strategies for digital game developers to create inclusive games for these users. Thus, usability and user experience evaluation sessions were performed to achieve these objectives, and the older generation's acceptance of technology during interaction with digital games was verified. The data collection methods were observation and the application of questionnaires, one before the tests to evaluate the profile of the public and another afterward to assess usability, experience and technology acceptance. The test was applied to 36 people aged 60 and over. The results showed that the elderly prefer mobile devices and use them more often. Despite their lack of experience with digital games, the test participants had a good experience, even with difficulties such as game time management and perception of screen elements.

Authors: Labian Antonio , García-Consuegra Jesús D. , Ortega Manuel
Published: April 2024

The migration of legacy applications to more advanced technology platforms has been a recurring theme in the academic and business sectors. This transformation is driven by the desire to overcome the limitations of traditional desktop applications and integrate advanced remote access and collaboration capabilities. Essential features not only for technology upgrade but also to enable organizations to take advantage of remote collaboration.The COVID-19 pandemic has accelerated this need, forcing many organizations to adopt remote work and online collaboration modalities, forcing them to transform their information systems. There are various methodologies and techniques, such as conversion, redeployment and wrapping, that offer different approaches to facilitate this migration by minimizing the effort required during the process. This paper specifically studies the migration of Java Swing applications to web environments, particularly those that incorporate collaborative functionalities. Several solutions that follow different migration strategies have been evaluated, performing a more detailed analysis of the Vaadin platform as an efficient tool to perform this migration, with limited effort and special attention to the inclusion of new collaborative functionalities. Finally, a migration procedure is defined that has been validated through two case studies.
From Trends to Experiences: Co-Creation with Generative Artificial Intelligence in Developing Interactive Multimedia Applications
Authors: Rozo-Torres Alexander , Latorre-Rojas Carlos J. , Sarmiento Wilson Javier
Published: April 2024

The emergence of generative artificial intelligence (GenAI) tools has ushered in new possibilities for creating diverse content, encompassing text, images, sound, videos, 3D objects, and even code for programming languages. Within this dynamic landscape, both significant challenges and opportunities arise in the field of interactive multimedia application development. It is imperative that the evolving trends in the utilization of these tools metamorphose into experiences that not only reflect but also facilitate the replication of models, methods, and development approaches. This paper contributes to the academic discourse by presenting three distinct development experiences. Each experience represents the initial steps of an incremental exploration process, thus contributing to exploratory research in this domain. These experiences are presented as case studies, with the first one analyzed retrospectively, and the latter two deliberately designed to scrutinize the challenges and opportunities associated with integrating generative artificial intelligence into the software development process, playing a significant role in a co-creation process. The results presented are qualitative, with detailed independent analyses for each case study, offering a comprehensive description of the findings. Thus, this paper presents a set of recommendations facilitating the transfer, replication, and improvement of these experiences by other multimedia development labs or teams.

Motor proficiency in young children with Prader-Willi syndrome: a preliminary report
Authors: Rubin Daniela A. , Hyde Adam M. , Fenning Rachel M. , Wilson Kathleen S. , Rose Debra J.
Published: April 2024

BACKGROUND: Systematic documentation of motor characteristics in young children with Prader-Willi syndrome (PWS) is vital as access to treatments improves.
AIM: To characterize motor proficiency (MP) in young children with PWS.
METHOD: Participants included 6 children (3 male and 3 female) with PWS and 13 children with neurotypical development (NT), (9 male and 4 female) ages 4-6 years. Five out of six children with PWS had been on growth hormone replacement therapy (GHRT) for >3 years. Some children with PWS exhibited cognitive delays and others performed within the average range (Intellectual quotient mean± standard deviation = 65.3 ± 7.62, range = 47 – 94). MP was measured using the Short Form of the Bruininks-Oseretsky Test of Motor Proficiency-Second Edition (BOT-2-SF).
RESULTS: Children with PWS scored lower than children with NT in all areas of MP except for fine motor integration. All children with PWS scored well-below average for total MP; children with NT scored average (n=10) or above-average (n=3) for total MP, respectively.
CONCLUSION: At this young age children with PWS universally exhibited poor MP despite most of them being on GHRT and some exhibited intellectual functioning in the average range. Evidence of BOT-2-SF floor effects underscores the need to refine assessment procedures and enhance measurement precision for this population.
Added cognitive demand from increased sensorimotor complexity resulted in better goal-directed movement following stroke: a novel finding in post-stroke recovery
Authors: Lowrey Catherine R. , Dukelow Sean P. , Moore Kimberly D. , Scott Stephen H. , Ritsma Benjamin R.
Published: April 2024

BACKGROUND: Stroke often causes impairments in goal-directed movements, which are commonly assessed using goal-directed reaching tasks. Here we present two individuals post-stroke who performed two robotic reaching tasks: 1. Visually Guided Reaching (VGR); reaching a cursor representing the fingertip to virtual targets, 2. Reverse Visually Guided Reaching (RVGR); where the cursor moves in the opposite direction of hand motion, requiring a novel cognitive rule. Participants are typically more successful at reaching targets in the simple VGR task compared to the more complex RVGR task (~92% of our database). The two cases are notable as they performed better on RVGR compared to VGR.
CASE DESCRIPTIONS: Case 1: 80-year-old patient with left hemorrhagic thalamic stroke, with interventricular extension, presenting with right hemiparesis/reduced motor control. They were unable to complete reaches to any targets in VGR (0/40 targets), but were able to reach ~30% of the targets (15/48) in RVGR.  Case 2: 76-year-old patient with a left ischemic pontine stroke, presenting with right hemiparesis/reduced motor control. They were unable to complete reaches to any targets in VGR (0/40) but were able to reach ~60% of the targets in RVGR (29/48).
INTERPRETATION: Better performance in RVGR compared to VGR may be associated with a “dual-task benefit” and has potential clinical implications, including informing neuro-rehabilitative strategies, potentially by including tasks with added complexity or cognitive components. These findings also highlight the utility of robotic tools to provide novel environments within which to identify unique patterns of impairments and abilities.
Symmetric analysis in a wheelchair basketball player during an incremental intermittent test: a case study
Authors: De Jesus Karla , Nascimento Lucas S. , De Jesus Kelly
Published: April 2024

BACKGROUND: Wheelchair basketball (WB) is a sport aimed at people with permanent disabilities in the lower limbs, with a functional classification system that allows the inclusion of various levels of injury from 1 to 4.5. Thus, it is natural that there is an increase in the search for greater sports performance which is related to physiological and kinematic analyses.
AIM: The present study aimed to compare the symmetry of temporal kinematic variables in the different zones of effort intensity during an incremental intermittent field test.
METHOD: The sample consisted of 1 male player aged (27 years), with spinal cord injury, with more than 5 years of gaming experience. The player performed the incremental field Yo-Yo Test - IR1 and the linear kinematics of the propulsive cycle was estimated.
RESULTS: The results indicated that wheelchair propulsion is a symmetrical movement, although some asymmetries seem to be perceived qualitatively, but without a statistically significant difference.
CONCLUSION: It was found that despite the injury to the right shoulder, there is symmetry in terms of wheelchair propulsion.

B
ACKGROUND: Changes in range of motion during partial and deep squats can affect the electrical activity of the knee extensor muscles. There are results’ divergences between studies that evaluated the effects of deep and partial squats on the electrical activity of the knee extensor muscles.
AIM: To systematically review the literature on the electromyographic activity of the knee extensor muscles during partial and deep squat exercises in subjects with strength training experience.
METHOD: The search included MEDLINE (via Pubmed), Scielo, EMBASE, in addition to a manual search, until June 2023. Cross-sectional observational studies comparing partial squats (up to 90º of knee flexion) and deep squats (maximum knee flexion) that evaluated the electrical activation through surface electromyography in men and women with strength training experience were included. Methodological quality assessment was performed using the adapted Downs and Black tool, as suggested by the Cochrane Collaboration. 
RESULTS: Of the 636 articles identified, four studies were included. The included studies presented electromyographic values of the two squat variations. No difference was found in the activation of the rectus femoris, vastus medialis and vastus lateralis muscles between partial and deep squats. Regarding methodological quality, one study was classified as having moderate and the other three studies showing high methodological quality.
CONCLUSION: The similarity in the knee extensors’ electromyographic activation between partial and deep squat exercises in men and women with strength training experience suggests that both exercises can be used for recruiting these muscles during physical fitness activities.

Published: April 2024

Sleep is involved in regulating many aspects of the body, including cell function, physical activity, and disease. Neurodegenerative diseases are often preceded by sleep disturbance. This disturbance is not just a non-motor symptom but also an important risk factor for developing the disease. It is now understood that the glymphatic system plays important physiological functions in the human body: maintaining the balance of interstitial fluid and clearing waste products from metabolism or death in the brain. Glymphatic system dysfunction contributes to the progression of neurodegenerative diseases. Importantly, sleep is involved in regulating the glymphatic system, which affects the clearance of pathological proteins in the brain, and may be an important pathway affecting the progression of neurodegenerative diseases. Here, we review recent advances in sleep disturbances and the glymphatic system in health and Parkinson's disease, hoping to identify potentially targetable avenues for future research and treatment of Parkinson's disease.
The role of brown adipose tissue in mediating healthful longevity
Authors: Zhang Jie , Kibret Berhanu Geresu , Vatner Dorothy E. , Vatner Stephen F.
Published: April 2024

There are two major subtypes of adipose tissue, i.e., white adipose tissue (WAT) and brown adipose tissue (BAT). It has been known for a long time that WAT mediates obesity and impairs healthful longevity. More recently, interest has focused on BAT, which, unlike WAT, actually augments healthful aging. The goal of this review is to examine the role of BAT in mediating healthful longevity. A major role for BAT and its related beige adipose tissue is thermogenesis, as a mechanism to maintain body temperature by producing heat through uncoupling protein 1 (UCP1) or through UCP1-independent thermogenic pathways. Our hypothesis is that healthful longevity is, in part, mediated by BAT. BAT protects against the major causes of impaired healthful longevity, i.e., obesity, diabetes, cardiovascular disorders, cancer, Alzheimer’s disease, reduced exercise tolerance, and impaired blood flow. Several genetically engineered mouse models have shown that BAT enhances healthful aging and that their BAT is more potent than wild-type (WT) BAT. For example, when BAT, which increases longevity and exercise performance in mice with disruption of the regulator of G protein signaling 14 (RGS14), is transplanted to WT mice, their exercise capacity is enhanced at 3 days after BAT transplantation, whereas BAT transplantation from WT to WT mice also resulted in increased exercise performance, but only at 8 weeks after transplantation. In view of the ability of BAT to mediate healthful longevity, it is likely that a pharmaceutical analog of BAT will become a novel therapeutic modality.

Published: April 2024

This observation aimed to understand the laboratory regulations, assess the availability of Personal Protective Equipment (PPE) in the laboratory, evaluate management practices, examine the completeness of laboratory equipment and materials, and observe the arrangement of laboratory space, equipment, and materials. This research was conducted in the basic biology laboratory at a university in East Kalimantan. The method employed in this research involved interviewing laboratory assistants and observing the laboratory conditions. The observations indicated that Laboratory A and B had complete personal protective equipment. However, there were some differences. For instance, the equipment and materials were complete in Laboratory A, whereas in Laboratory B, they were incomplete because the laboratory was newly built. Another difference was in the usage of the laboratories; Laboratory A was used for practical sessions, seminars, and classroom activities, while Laboratory B was solely utilized for practical exams. For future researchers, it is suggested that laboratories be explored for both practical sessions and classroom activities, rather than just classroom spaces.

Published: April 2024

One of the emerging scientific developments is science-based local wisdom, or "ethnoscience." This research examines the urgency of ethnoscience when viewed from a philosophical perspective with an anthropological, ontological, and axiological perspective approach. This research uses a library research method with relevant sources related to the studied topic, such as books, scientific articles, and other relevant sources. The results of this study present how critical philosophical studies are to a science that is being developed, especially those that involve community culture. In addition, anthropological, ontological, and axiological perspectives provide an idea of a point of view that not only always refers to the research process but also the need to pay attention to the norms and values of the local culture. That way, future research related to ethnoscience has excellent potential to continue to be carried out through rational considerations and benefit science, culture, society, and the nation.

Authors: Triyono Triyono
Published: April 2024

The objectives of this study are to stimulate more activity and enhance student learning. In this study, the Discovery Learning methodology is applied. This study follows the method of Kemmis and McTaggart's classroom action research. Thirty students from SMK Negeri 1 Cangkringan's XII ATR 1 class served as the study's subjects. Test papers were used to gauge student learning outcomes, while observation sheets were used to estimate student activities. The percentage technique is used to look at the connection between activity and student learning outcomes. Learning success is measured using three variables: the growth of the learning activity, the grade point average, and the proportion of students who finish. The findings revealed a propensity for student activity to rise in cycles 1 and 2. The average class score grew from cycle one to cycle two by 71.5 points to 85 points. More students finished the cycle, from 60% in cycle 1 to 86.7% in cycle 2. Thus, the discovery learning paradigm can enhance class XII students' engagement and learning outcomes.

Published: April 2024

This study aimed to examine the factors influencing individuals' behavioral intentions to use hydraulic elevators through Structural Equation Modeling (SEM) analysis and assess their feasibility across five crucial aspects: Economic, Technical, Legal, Operational, and Scheduling. We found that perceived benefits, perceived risks, and social influence significantly impact behavioral intentions. The feasibility analysis results indicate that hydraulic elevators are economically, technically, and operationally viable, with mean scores of 0.68, 5.03, and 4.98, respectively. However, potential legal and scheduling challenges were identified, with mean scores of 0.33 for both aspects. The study's implications suggest addressing individuals' perceptions of benefits, risks, and social influence, as well as informing decision-makers about practical considerations for successful hydraulic lift implementation. Despite limitations, such as self-reported data and cross-sectional survey design, the study provides valuable insights into factors influencing behavioral intentions and feasibility considerations. Future research could explore longitudinal data and additional factors, such as environmental concerns, accessibility, and user experience.

The Ministry of Education (MoE) provided technology support to strengthen the educational capacity during the COVID-19 Pandemic. MoE’s support include educational tablets (DIKTI Edu),  SPADA DIKTI (online platform of distance learning), internet satellite (VSAT), and Mobile VSAT. This research aims to assess the impact of three main aspects: the support of online learning, inequality in access to education, and increasing the quality of lecturers and the learning process. A survey of 657 undergraduate students was conducted based on a purposive stratified sampling in underdeveloped areas from four chosen provinces. Descriptive statistics and a before-after tests were done. Results shows that the devices were received well  and has been used as their primary device for distance learning. Moreover, the impact was promising because all three aspects indicated significant positive effects. Nonetheless, the MoE still must tackle some drawbacks:1. Students facing technical barriers feel that improvement in the accessibility to install vital software needed and providing a device with a sim card slot ,for online learning is prominent, 2. Socialization of SPADA DIKTI and access to more relevant materials for broader students is also recommended and 3. In-depth studies on student I.T. awareness and further dynamics of grades should be conducted.

Abstract
Research on optimizing the concentration of CaO catalyst from green mussel shell (Perna viridis) in the transesterification reaction of oil (Hevea braziliensis) has been conducted. This research aims to obtain the optimum concentration of CaO catalyst on the characteristics of methyl esters produced, which are density (40 °C), kinematic viscosity (40 °C), and acid numbers. CaO catalysts were obtained from calcination of green mussel shells for 4 hours at 1000 °C and characterized by XRD. Rubber seed oil extraction was carried out using the socletation method using n-hexane solvent for 7.5 hours followed by a degumming process using 2.5% (w/w sample) of concentrated H3PO4. Pre-esterification with 1:3 oil:methanol mass ratio using 0.5% (w/w sample) concentrated H2SO4 at 65 °C. Transesterification with 1:4 oil:methanol mass ratio using CaO catalyst with concentration of 2.5; 5.0; 7.5; 10.0; and 12.5% (w/w sample) at 65 °C. The results showed that the optimum concentration of CaO catalyst was 5.0% with the characteristics of methyl ester namely density value (40 °C) 0.8832 g/mL, kinematic viscosity (40 °C) 5.22 mm2/s, and acid number 1,42 mg KOH/g sample. GC-MS analysis at optimum conditions shows the largest composition of methyl esters produced is methyl octadecenoate, methyl hexadecanoate, and methyl stearate

Nepal is highly vulnerable to seismic activity. This review seeks to explore the impact of earthquakes on human populations in terms of casualties and injuries, as well as to pinpoint the risk factors associated with these outcomes. An earthquake measuring 7.8 on the Richter scale struck near Gorkha, Nepal, on April 25, 2015, resulting in the loss of nearly nine thousand lives, extensive property damage, and the destruction of numerous historical and cultural landmarks. Data sourced from the UNDRR, Ministry of Home Affairs, and the United States Geological Survey were analyzed using the ArcGIS software tool. The study offers a comprehensive examination of earthquake-prone regions at regional, national, and global levels. By analyzing recent significant earthquakes along with their associated losses and damages, it underscores the importance of precautionary measures and risk analysis in reducing vulnerability and enhancing preparedness among researchers and stakeholders.
From 737 Conclusions by Jean Cabrol to Giovanni Pico’s 900 Conclusions
Authors: Copenhaver Brian
Published: May 2024

The heart of Pico’s legend, still beating today on the internet, is his prodigious, omnicompetent, self-sufficient genius – original, parahuman mastery of everything knowable at an unbelievably early age. This durable tale has floated free of evidence, but Pico’s 900 Conclusions has given weight to part of it. Yet the ballast crumbles under the load of textual facts. The young prince did not know everything. He got by with a more than a little help from his friends: Marsilio Ficino, Elia del Medigo, Flavius Mithridates and especially Jean Cabrol.
Wind Lore as Environmental Knowledge in Southern Vanuatu

Published: April 2024

Wind lore constitutes an important domain of environmental knowledge in eight cultures of southern Vanuatu (Aneityum, Futuna, Aniwa, Nafe, Naka, Netwar, Nanu, and Nahual). Our study reviews previous studies in Oceania which document wind systems as used primarily for long-distance navigation. The named winds of southern Vanuatu are not merely abstract directional markers, nor primarily for use in navigation, but are closely tied to the local geography, agriculture, health, and seasonal changes. Winds are part of everyday, embodied experience and cognitive-spiritual understanding of the environment. Wind lore is gradually being forgotten, but can still be described in detail by experts. We conclude by situating wind lore within a culture complex that includes knowledge of agriculture, fishing, time-reckoning, and weather magic. Our documentation of these systems is ongoing, and in collaboration with local experts.

The mangrove area in Mentawir Village has the potential to be developed into an ecotourism site in Nusantara Capital City (Ibu Kota Nusantara or "IKN"), Indonesia. Apart from the mangrove conservation area, some myths add to the tourist attraction of IKN. Various myths continue to live and develop in the lives of the Paser indigenous people in Mentawir Village (Sepaku District, East Kalimantan Province, Indonesia). The functionalization of the myth is expected to support mangrove ecotourism. So, how can existing myths affect the use of mangroves to support the development of mangrove ecotourism in IKN? Ethnographic data collection conducted through participatory observation and in-depth interviews can reveal the existence of myths that affect the use of mangroves in people's lives. The results showed that three myths developed in Mentawir Village: the myth of yellow mangroves (lemit mangroves/bakau lemit), the myth of the Mentawir River (Sungai Mentawir), and the mystery myth of the peace stone (misteri batu perdamaian). Using the Malinowski cultural functionalization approach, it can be seen that these myths can support the development of mangrove-based ecotourism and creative economy as IKN tourist attractions that can support community welfare.
