Authors: Nyawo B G , Buthelezi Alan B , Khumalo Nontobeko Prudence , Ajani Oluwatoyin Ayodele
Published: June 2024

This research examines the impact of political party affiliations and interference on school management in the Zululand District of South Africa. Using an interpretive research approach and qualitative methods, including an extensive review of existing literature and data collection through interviews, the study conducts semi-structured interviews with 21 individuals from three public primary schools. It also explores the influence of political factors on School Governing Bodies (SGBs), including their involvement in party politics and the challenges they face in enhancing their capacities. The findings confirm significant political interference in school governance, particularly in rural areas where political affiliations influence decision-making. SGBs often align themselves with political parties, leading to governance inefficiencies and conflicts among parent governors. Through the lens of participatory democratic theory, the study reveals governance capture in rural schools, with discriminatory practices and corruption arising as consequences of political intervention. The recommendations call for empowering SGBs to navigate political pressures through policy reforms, ensuring autonomy for parent governors, and reassessing the permissible extent of political influence within the governance framework. Additionally, the Department of Basic Education (DBE) is urged to address socioeconomic factors exacerbating corruption and to uphold integrity within school governance structures. By addressing the influence of politics and enhancing transparency, the DBE can cultivate a more equitable and effective educational environment for rural South African students.

Application of Q-learning Method for Disaster Evacuation Route Design Case Study: Digital Center Building UNNES
Authors: Alrahma Hanan Iqbal , Anan Nugroho  , Hastawan Ahmad Fashiha , Arief Ulfah Mediaty
Published: June 2024

The Digital Center (DC) building at UNNES is a new building on the campus that currently lacks evacuation routes. Therefore, it is necessary to create an evacuation route plan in accordance with the Minister of Health Regulation Number 48 of 2016. Creating a manual evacuation route plan can be inefficient and prone to errors, especially for large buildings with complex interiors. To address this issue, learning techniques such as reinforcement learning (RL) are being used. In this study, Q-learning will be utilized to find the shortest path to the exit doors from 11 rooms on the first floor of the DC building. The study makes use of the floor plan data of the DC building, information about the location of the exit doors, and the distance required to reach them. The results of the study demonstrate that Qlearning successfully identifies the shortest evacuation routes for the first-floor DC building. The routes generated by Q-learning are identical to the manually created shortest paths. Even when additional obstacles are introduced into the environment, Q-learning is still able to find the shortest routes. On average, the number of episodes required for convergence in both environments is less than 1000 episodes, and the average computation time needed for both environments is 0.54 seconds and 0.76 seconds, respectively.

Published: June 2024

Detecting DNA sequence mutations in cancer patients contributes to early identification and treatment of the disease, which ultimately enhances the effectiveness of treatment. Bioinformatics utilizes sequence alignment as a powerful tool for identifying mutations in DNA sequences. We used the Needleman-Wunsch algorithm to identify mutations in DNA sequence data from cancer patients. The cancer sequence dataset used includes breast, cervix uteri, lung, colon, liver and prostate cancer. Various types of mutations were identified, such as Single Nucleotide Variant (SNV)/substitution, insertion, and deletion, locate by the nucleotide index. The Needleman Wunch algorithm can detect type and index mutation with the average F1-scores 0.9507 for all types of mutations, 0.9919 for SNV, 0.7554 for insertion, and 0.8658 for deletion with a tolerance of 5 bp. The F1-scores obtained are not correlated with gene length. The time required ranges from 1.03 seconds for a 290 base pair gene to 3211.45 seconds for a gene with 16613 base pairs.

Authors: da Silveira Guimarães Bruna , França Kepler Borges , de Sousa Santos Danilo Freire , do Nascimento João Alexandre Rodrigues , Gomes de Matos da Costa e Silva Bernardo José
Published: June 2024

The cultivation of microalgae in domestic wastewater offers a sustainable solution for the treatment of effluents, while at the same time producing biomass rich in lipids, potentially usable in the production of biofuels. Furthermore, reuse contributes to the treatment of wastewater, transforming a byproduct into a valuable source of nutrients for the production of microalgae biomass. This study involves the production of microalgae in open cultivation, using domestic effluents as a source of nutrients in brackish environments, to study the potential for biodiesel production. Intracellular lipids were between 17 and 20%. As for the bioremediation capacity, the results showed removal levels greater than 95% of nutrients, as well as bacterial and pollutant load reduction. The growth kinetics and the prediction of theoretical kinetic models through the use of computational tools show significant differences, due to the lack of control of process parameters in open cultivations. Based on the literature review and market research, a cost analysis for large-scale production in open crops was made, comparing with closed crops and finding lower costs in the implementation, maintenance and production of biodiesel in the production open.
Application of artificial countermeasures to enhance desilting efficiency in a reservoir under normal and extreme events
Authors: Lee Fong-Zuo , Huynh Nguyen Nhat Lam
Published: June 2024

The influx of flood-induced turbidity flows with high sediment concentrations into the reservoir can create sediment deposition issues, potentially jeopardizing water supply reliability. Efficient management of reservoir water resources is imperative for sustainable utilization. Evaluating the need for reservoir desilting involves comprehending the inflow and outflow dynamics of water-sediment discharges, the capacity of existing outlet structures, reservoir operation objectives, and available desilting technologies. However, given the altering hydrological conditions due to the impacts of climate change, there is a necessity for adaptive methods to ensure reservoir storage maintenance. Consequently, this study introduces the utilization of a flushing channel with artificial guiding structures to enhance desilting efficiency. A 2D numerical model offers convenient computational tools for assessing water-sediment transport behaviors across various operational scenarios based on reservoir management strategies. Data obtained from field observations is collected and analyzed to calibrate and verify the numerical model. By employing 2D numerical modeling, sediment concentration and desilting efficiency are calculated to support effective desilting operations within a reservoir. Simulation results indicate that the integration of additional artificial guiding structures at the bottom of the reservoir can enhance sedimentation mitigation outcomes by approximately 17.63% under normal conditions and by 5.27% under extreme hydrological conditions.

Published: June 2024

El objetivo del artículo es discutir la problemática de la educación en el contexto fronterizo peruano-chileno. Para ello el trabajo de campo se situó durante el segundo semestre del 2022 en la ciudad de Tacna. Metodológicamente se desarrolló una estrategia cualitativa basada en entrevistas semiestructuradas dirigidas a actores de la frontera tales como comerciantes, transportistas y docentes. Los resultados de la investigación dan cuenta de que el problema entre educación y movilidad fronteriza adquiere particularidades en el contexto emigratorio o de la ciudad de origen. Esto último, a diferencia de la producción científica previa, que ha hecho mayor énfasis en el problema educativo en relación con la inmigración, el lugar de destino migratorio o de movilidad. Asimismo, las evidencias de investigación invitan a repensar críticamente el concepto de movilidad fronteriza considerándose el giro de la movilidad, la movilidad interconectada y la movilidad de saberes en el contexto fronterizo.
Honra, família e política
Authors: Sousa dos Santos Antonio Nacilio
Published: June 2024

A pesquisa estudou o conceito de “honra de família” a partir do universo de uma elite política no sertão pernambucano. A noção de honra engloba um sistema de valores e afetos que ainda hoje possui força simbólica para interações entre membros que se orgulham de compartilhar do mesmo sobrenome, “seja por meio da exaltação do que chamamos de ethos de poder familiar” (Sá; Campos, 2022), seja pela força de reconversão que ganha esse orgulho num jogo por distinção social com resultados práticos para a permanência no poder político partidário. Dito isso, o referencial teórico para a análise está circunscrito através dos trabalhos de Becker (2008), Bourdieu (1989, 2008, 2017) e Elias (2001). Fez-se uso da metodologia bibliográfica para a obtenção dos dados empíricos a partir de dois livros de memórias publicados por membros do grupo objeto deste estudo de caso, a família Pereira do Pajeú. Concluiu-se que a honra familiar, ainda hoje bastante utilizada por grupos políticos familiares, é utilizada para a permanência e perpetuação do poder político local tendo como instrumento, neste caso, a utilização de publicações de registros bibliográficos familiares.

Guidance and counseling services can be done through the form of individual or group. A group shall be led by a counselor who has been previously trained in guidance and counseling. A leader must choose a leadership style with priority given to the achievement of goals within the group such as achieving cohesion within the group. The homeroom approach is how a counselor is able to create a group atmosphere of intervention, like a family atmosphere or a home atmosphere. The study aimed to review the reseach of homeroom intervention in guidance and counseling. The literature review is carried out in five stages: formulation of research questions, search for literature, processing of data, and assessment of the quality of filtering received and not received. A total of 100 articles were identified and subjected to PRISMA analysis, resulting in the selection of 12 articles for further in-depth examination. The criteria for articles included discussions on group leadership, counseling groups, strategies in group leadership, targeting students and guidance and counseling teachers in 2013-2023. The results showed that the homeroom approach can be considered as one of the group leader's qualifications. A group leader must have the ability to listen actively, receive, pay attention, create a warm and welcoming atmosphere, connect among members. A homeroom approach can facilitate the group leader to create an atmosphere of warm, welcoming, safe and comfortable within the group dynamics.
Reactualising the problem of social engineering and digital security
Authors: Kolinko Maryna , Petryshyn Halyna , Chumak Halyna
Published: June 2024

The article explores the current aspects of social engineering in the digital age. Social engineering is considered as a strategic technology of constructing new meanings, principles, rules and facts of social interaction. The socio-philosophical concepts of K. Popper, P. Sorokin, and R. Silverstone are analyzed in the context of constructive proposals of social engineering. The application of historical and philosophical intellectual constructs to the practices of social transformations is described in the article. The article reveals the possibilities and limitations of digital technologies in social engineering. The risks of creating new tools and algorithms for manipulation, disorientation of users of virtual technologies by social engineering methods are shown within the framework of the digital security problem. The diversity of views on the essence of social engineering and the analysis of its spheres of application problematize the interpretation of its social role and meaning. The methods of constructing social events and interfering in people's lives require critical evaluation. The implementation of AI in social engineering developments leads to the new risks, which are systematized in the article. They are related to the manipulation of public consciousness, distortion of identification and personalisation methods, financial fraud, and violation of human security.
Digital Consciousness and Identity
Authors: Veliev Daxil Jahangir
Published: June 2024

The aim of the study is to analyze how the development of digital consciousness and the widespread ingress of digital technologies into daily life affect the under-standing and formation of human identity in contemporary society. This aim encompasses several key research directions: studying the impact of virtual agents and artificial intelligence systems with elements of digital conscious-ness on individuals’ self- perception and their views of the world; identifying the role of digital media in the process of forming and rethinking social identity; analyzing the consequences of continuous interaction with digital technologies and content for personal development, self-esteem, and self-presentation; considering ethical and philosophical issues related to the creation and interaction with digital conscious-ness; reflecting on potential pathways for the development of relationships between humans and digital technologies, assessing opportunities and risks associated with a closer integration of artificial intelligence into the social and personal spheres of people’s lives. The result of exercising this interdisciplinary approach and combining various theories and observations show that people, with the help of technology, are taking part in developing their own identity, further proving the impact of digitalization on an individualistic and collective level; digital technologies also tend to have a profound and transformative impact on the peoples’ self-awareness and relations in a globalized world; furthermore, the use of digital technologies proves to be an effective means of global and subtle influence on the life, behavior and beliefs of modern people. It has been argued that postmodernism and cyberculture, in addition to having an ontological connection, share a model of world perception, which is not affiliated with any type of hierarchical model. The result of the author's reasoning is the conclusion that changes in technology or data loss are not mere technical problems – people end up feeling serious consequences of them, including drastic shifts in their personality, cognitive abilities and general well-being. This deeply affects the user’s ability to maintain their productivity, interact with information, and, more broadly, their ability to function in everyday life. Such situations highlight the need for the development and implementation of strategies and policies that consider potential vulnerabilities associated with technology dependence and aim to minimize the negative consequences of such dependence. Ethical considerations around cognitive extenders should include discussions on precautionary measures and development standards that ensure protection and support for users in the event of technological changes, updates, or failures. This might involve creating more resilient systems for data storage and recovery, developing more transparent and predictable update schemes, and introducing policies that support users’ cognitive autonomy and well-being.

Authors: Asrofi Muhammad , Septyandy Muhammad Rizqy , Indra Tito Latif
Published: June 2024

Pekalongan is located in the northern part of Java Island, directly adjacent to the sea in the north. Natural disasters that often occur in Pekalongan are floods, especially in the north of the area, which has a height of 0 meters above sea level. In addition, Pekalongan also has a relatively low land slope of around 0 – 5%, which makes it challenging to distribute water and construct drainage. This study aims to be able to perform predictive modeling of flood-prone areas for the next five years. This study used eight parameters: rainfall, elevation, slope, distance to the river, distance to the sea, groundwater table to surface, soil type, and land use. This research used the Long Short-Term Memory (LSTM) method to predict rainfall parameters using the Python programming language with Jupyter Notebook software. Later, the data will be used as training and test data. Training data testing and tests are conducted to find the minimum failure or error value. The weight scoring method is carried out on each parameter to indicate areas with a high flood vulnerability level. The results showed that Pekalongan has a medium to very high vulnerability level, with a dominant high vulnerability level. The very high level of vulnerability is prevalent in the northern part of the research area, which is directly adjacent to the sea or in the North Pekalongan District. Floods that occur in the northern part of the study area are not only due to high levels of rainfall but can also occur due to the inflow of seawater towards the mainland resulting from high tides and high sea waves. The southern region of the study area has a smaller vulnerability level than the northern region, which has a medium to high vulnerability level.Keywords: Flood ∙ Hazard ∙ Precipitation ∙ LSTM ∙ Rainfall

Lately, public policy as a major political instrument has failed terribly in ensuring desirable internal security sector administration in Nigeria. This paper investigates the Nigerian public policy and internal security governance challenges using poverty, unemployment, gross domestic product (GDP), and foreign direct investment (FDI) as the baseline. The incident of poverty in Nigeria in 2020 reveals that the six geopolitical zones in Nigeria experience a severe rate of poverty, owing largely to an unprecedented rate of internal security problems (Olurounbi, 2021). The paper explores secondary research methods, secondary sources of data, and secondary data analysis (SDA) techniques. The paper reveals that Nigeria’s crucial economic metrics, such as poverty, unemployment, GDP, and FDI, have been significantly aggravated by the country’s poor internal security situation. As a result, residents are now experiencing significant economic hardship, negatively impacting Nigeria’s current internal security governance situation. The paper concludes that Nigeria’s internal security sector governance, particularly in the last ten years of democratic administration, has failed reasonably to meet Nigerians’ expectations. Following the findings, the paper advocates, among others, for a genuine electoral process capable of bringing in skilled people to public policy decision-making and program execution in Nigeria.

Published: June 2024

Background/Aim. Cardiovascular diseases are the most common cause of mortality and morbidity worldwide, with the highest incidence in low-middle-income countries. Dobutamine stress echocardiography (DSE) plays a significant role in diagnosing coronary artery disease. The aim of the study was to examine the influence of gender on the accuracy of DSE and on the prognostic significance of the left ventricular wall motion score index (WMSI) as a parameter of DSE for adverse cardiovascular events (ACEs). Methods. The prospective, observational study conducted at the Clinic for Cardiovascular Diseases of the University Clinical Center of the Republic of Srpska, Bosnia and Herzegovina, included 143 patients who, due to suspicion of coronary disease, under-went a DSE from January 1, 2021, until February 1, 2022. ACEs that we observed one year after DSE were: unstable angina, acute myocardial infarction, percutaneous coronary intervention, in-stent restenosis, aortocoronary bypass, heart failure, and death. Results. A positive DSE was more common in men (45%) compared to women (25%), which was statistically significant (p < 0.05). The sensitivity of the test in men was 96.0%, and the specificity was 93.9%. In women, the sensitivity was 86.7%, and specificity was also 86.7%. ACEs were more frequent in men (43%) than in women (19%), which was statistically significant (p < 0.01). In men, WMSI had a sensitivity of 96.0% and a specificity of 82.4%. In women, WMSI had a sensitivity of 93.3% and a specificity of 90.6% in predicting ACEs. Conclusion. Our results confirmed the influence of gender on the accuracy o f D SE i n diagnosing coronary artery disease. WMSI as a parameter of DSE was identified as a significant prognostic factor for ACEs in both sexes, with the sensitivity being higher in men and specificity in women.

Published: June 2024

Background/Aim. High-grade glioma (HGG) is an interstitial cell-derived primary tumor of the nervous system. The current guidelines for the diagnosis and treatment of glioma recommend the maximum safe range of tumor resection for treatment methods. Adjuvant concurrent chemoradiotherapy is recommended after surgery, followed by six cycles of single-drug chemotherapy, temozolomide. Evaluation of the early efficacy of concurrent chemoradio-therapy after HGG surgery, especially for patients with a high risk of recurrence, is a crucial step in enhancing the treatment efficiency for patients diagnosed with HGG. In this study, we investigated the clinical utility of magnetic resonance (MR) spectroscopy (MRS) in assessing the early curing impact of concurrent chemoradiotherapy following HGG surgery. Methods. A total of 50 patients with incomplete resection or suspected residual postoperative HGG, treated in the radiotherapy department of our hospital between January 2016 and June 2021, were selected for routine concurrent chemoradiotherapy. Conventional MR imaging and MRS were performed one week prior to treatment and one month after treatment to assess changes in specific brain metabolites. All 50 patients were followed up for 6 to 12 months. Based on the follow-up results, the patients were divided into two groups: the tumor recurrence group and the tumor suppression group. One month after the end of the treatment, the differences in levels of brain metabolites between the two groups were analyzed using MRS. Results. The levels of N-acetylaspartate (NAA) and creatine (Cr) increased after radiotherapy, while choline (Cho) peak value, and Cho/Cr, NAA/Cr, and Cho/NAA ratios decreased compared to pre-treatment levels. There were statistically significant differences in the NAA peak value, and Cho/Cr, and Cho/NAA ratios in the tumor enhancement area before and after treatment (p < 0.05). There were also statistically significant differences in Cho/Cr ratio in the peritumoral edema area before and after treatment (p < 0.05). Conclusion. After concurrent chemoradiotherapy, MRS can be used to detect early metabolic changes in the tumor enhancement and peritumoral edema areas of HGG.
PCAOB Inspections and Auditor Liability
Authors: Grenier Jonathan H. , Robertson Jesse C. , Simon Chad A. , Vinson Jeremy M.
Published: June 2024

The PCAOB has been inspecting firms for almost 20 years, yet there is little evidence regarding the effect of PCAOB inspections on auditor liability. We examine conditions under which a clean PCAOB inspection finding (at the engagement level) provides auditor liability protection for an audit subsequently called into question. Using source credibility theory, we predict and find that the defense introducing a clean PCAOB inspection finding for the litigated engagement reduces jurors’ negligence assessments by increasing the perceived credibility of the firm’s defense. We also find that, if the plaintiff introduces a PCAOB-issued control criticism (firm-wide level), jurors’ negligence assessments increase, regardless of whether a clean PCAOB inspection finding for the engagement is present. Collectively, results suggest that PCAOB inspection findings influence jurors’ negligence assessments. These findings have implications for audit firms, the PCAOB, and other public policy makers, as well as attorneys and triers of fact in audit litigation.

Authors: Wang Shanshan , Wang Xingsong , Yu Shanshan
Published: June 2024

The positioning of paddy field weeding wheels is of great significance for compensating the operation deviation between the weeding wheel and the seedling row in paddy field mechanical weeding. In this paper, a visual positioning method for determining the three-dimensional coordinates of weeding wheels in the camera coordinate system is proposed. By fixing the laser rangefinder with the weeding wheel, the proposed method converts the positioning of weeding wheels into solving the relative pose relationship between the laser rangefinder and the camera. Then, based on the constraints of the laser spots on the AprilTag calibration plane, a nonlinear optimization model is established to obtain the relative pose parameters. In the experiment, two evaluation indicators were proposed to evaluate the calibration accuracy. The experimental results showed that the proposed visual positioning method of the weeding wheel can reach a mean positioning error of 2.766 mm and a mean pixel error of 7.161 pixels.

This work was carried out to perform the comparative analysis on the effects of palm oil processing waste (POPW) on soil Microorganisms. Three soil samples were collected from three different locations, North bank, Wurukum, and High-level where palm oil processing waste are being discharged. The samples were analyzed, Soil samples unimpacted with POPW served as control. The physicochemical parameters of the soil samples that are pH, moisture, Temperature and particulate nature were analysized using standard methods. The total coliform count, total viable count and total fungal counts were evaluated using the pour plate method. Result showed that the Total Coliform, Total viable count and Total fungal counts (200.77 ±16.525 mean of the three samples, 22.55 ±2.041 mean of three samples and 28.88 ±2.590 mean of the three samples) of the impacted soils were lower compared to the values (291.00 ±13.00 in control soil, 118.33 ±18.717 control soil and 44.33 ±1.527 control soil respectively) of the un-impacted soils which served as control. The bacterial genera isolated from these soil samples include; Bacillus spp, Klebsiella, Staphylococcus spp, Salmonella spp and Proteus spp. The fungal genera isolated from soils with POPW includes; Aspergillus spp, Rhizopus spp, and Mucor spp, the results obtained indicates that POPW have immediate negative impact on soil microbiota as their application could lead to changes which affects soil microbial communities. Therefore, it would be advised that proper guidelines be set up for possible pre-treatment and safe discharge of POPW, in other to avoid its effect on soil micro biota and soil fertility

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease of unknown aetiology, with the broad range of antibodies affecting various organs and tissues, leading to rapid disability and even to lethal outcome. Our objective was to make an analysis of the results of relevant global studies about genetic mutations, spectrum of antibodies and cytokines involved in the pathogenesis of SLE. The search was conducted in PubMed and Google Scholar platforms using keywords “systemic lupus erythematosus”, “genetic mutations”, “autoantibodies”, “cytokine production”, “sequencing”, “NGS" and "exome". Several genes were found to be involved in the pathogenesis of SLE, the majority of which were associated with B- and T-cell abnormal activation. The results of different studies revealed an association of active SLE with the increase in specific circulating autoantibodies. Based on the results of the current review, a preliminary list of autoantibodies, genes and cytokines associated with the development of SLE was prepared. Future directions will include the assessment of association of genes, antibodies and cytokines in SLE patients from the local Kazakh population, and the development of genetic-immunologic panel for the early diagnosis of this disease.

The principles in treating complex mandibular fractures have changed recently, although the objective of re-establishing the occlusion and masticatory function remains the same. Technological upgrades like 3D-printed customized plates and implants have replaced traditional stock plates by achieving safe and desirable anatomical and functional restoration with reduced operative time. In this case report, we aimed to design and employ customized 3D-printed titanium plates for mandibular reconstruction in a case with complex mandibular fracture. A preoperative CT scan of the patient was taken to evaluate the displacement between the fractured segments. Virtual surgical planning was done, and 3D-printed titanium plates were simulated, customized, fabricated, and placed following Champy’s line of osteosynthesis for the approximation of fractured segments and to guide the occlusion during surgery. A postoperative CT scan was taken and overlapped with the preoperative virtual surgical plan scan to assess the interfragmentary gap after reduction and the amount of deviation. The result achieved was satisfactory, with no complications reported.
The use of customized 3D printed-Ti plates in the treatment of mandibular fracture had better accuracy and adaptability to the bone, avoided the need for plate bending, improved operator efficiency, and resulted in fracture reduction with satisfactory outcomes.

Pelargonium is a genus belonging to the Geraniaceae family, found within the Angiospermae division, the Dicotyledoneae class, and the Geraniales order. It is the second biggest genus of the family; it has about 280 taxa. In the past, Pelargonium species were characterized by presenting large and red roots, from which preparations were used in the treatment of diarrhea, dysentery, anemia, and weakness. This article is a bibliographic search carried out in different databases that focus on chemical and physical features of Pelargonium and also some of the extraction methods. Currently, there are a variety of studies that affirm the different properties of the species of the genus Pelargonium, among which the activities stand out: antituberculous, antioxidant, antitumor, antibacterial, antifungal, antiviral, and immunomodulatory. Therefore, they are used in both the pharmaceutical and food industries. The most relevant species of this genus is Pelargonium sidoides, which has a broad range of biological properties, from which a standardized hydroalcoholic root extract was formulated, known as EPs® 7630, which has been authorized by the EMA and is listed in the European Pharmacopoeia. It is important to continue with the clinical studies to be able to analyze the other properties that Pelargonium has in order to contribute to the pharmaceutical industry.

Signs And Meanings Of Pamali Utterances In The Religiosity Of Kampung Naga Indigenous Communities: A Semiotic Theory Perspective
Authors: Widiawati Nani , Nor Mohd Roslan Mohd , Restiani
Published: June 2024

This research is motivated by differences in people's beliefs regarding the Pamali (taboo) tradition, which is considered by some groups to represent wisdom, but by as a type of superstition that must be avoided. This results in the Pamali tradition beginning to be marginalised from modern life. However, in the Kampung Naga, one of the villages in Indonesia , the tradition is still maintained in the practice of religion and modernisation. The paper aims to analyse Pamali utterances based on the perspective of semiotic theory and their relationship with the religiosity of the Kampung Naga indigenous community. The qualitative research uses an phenomenological design that applies linguistic theory as an analytical tool. It was found that according to the theory of meaning, Pamali utterances are based on the relevance of the relationship between sign, referent, and interpretant. Pamali is interpreted as taboo by society, and therefore people do not violate it. The content of the message in Pamali utterances is in harmony with the content of the Islamic message, so the reflection is a crystallisation of the religious teachings adhered to by the village people.
