Published: September 2024

Introduction

A variety of methods, including hand instruments, high-speed and low-speed handpieces, chemomechanical techniques, air abrasion, ultrasonic instrumentation, and lasers, could be used to treat dental caries. The development of rotary devices like the micromotor and airotors was prompted by the traditional method of treating caries, which only used hand instruments and was painful and ineffective.

Aim

To evaluate the efficiency of conventional and disposable airotor in treating dental caries in children aged 6–12 years old.

Materials and methods

The split-mouth randomized controlled trial was designed on 60 teeth from 30 patients aged 6–12 years, involving caries removal techniques using conventional and disposable airotor. Ericson scale, stop-watch, animated emoji scale, and verbal pain scale were used to evaluate efficacy, time taken, patient acceptance, and pain threshold during caries removal.

Results

Intergroup comparison in terms of time taken for caries removal, patient acceptance and pain threshold showed a statistically significant difference between the conventional and disposable airotor concerning patient acceptance (P = 0.01) and pain threshold (P = 0.04). No statistically significant difference was found between the groups in caries removal efficacy (P = 0.55).

Conclusion

Caries removal time and clinical efficacy were almost comparable with disposable and conventional airotor. The disposable airotor had more patient acceptance and less pain threshold when compared to the conventional airotor.

Authors: Al-Germ Hager R. , Abdalla Ali I. , Salama Mirvat M.
Published: September 2024

Aim

To evaluate and compare the marginal integrity of composite resin restorations made by two different preparation techniques: conventional drill and hydro-abrasion.

Materials and methods

Forty extracted human premolars with simple occlusal caries were used. The teeth were fixed with sticky wax to the base of plastic cylinder. The cylinder was filled with self-curing acrylic resin so that only root was embedded within the self-curing acrylic resin. The teeth were randomly divided into two main groups (n = 20) according to the preparation technique. Group I: class I cavity preparation was done by the conventional drill method using a #245 Carbide bur and contra angle high-speed hand piece with water coolant. Cavity design was restricted to remove caries with no undercuts, and no beveling. Group II: class I cavity preparation was done by Aquacut Quattro air hydro-abrasion unit which uses a gamma irradiated aluminum oxide particle as abrasives (29 μm), cutting fluid and a hand piece of 0.6 mm diameter tip. The preparation in both groups was restored by the same composite resin (Grandio) and adhesive systems (Futurabond U) following the manufacturer's instructions. All specimens were thermocycled. Impressions for each tooth was made using a polyvinyl Siloxane material. The impressions were then poured with epoxy resin. These replicas were examined under scanning electron microscope. Scanning electron microscope photographs of tested samples were used for the gap evaluation.

Results

It was found that, group I recorded higher mean value of marginal gap length (157.57 ± 35.15 μm) than group II that recorded (69.55 ± 20.02 μm). Also, group I recorded higher mean value of marginal gap length ratio (10.72 ± 2.47) than group II that recorded (7.44 ± 2.69).

Conclusion

Conventional drilling technique was faster than the hydro-abrasion technique for cavity preparation. Hydro-abrasion technique showed more marginal adaptation than conventional drilling technique.
Prevalence of histidine-rich protein 2 deletion among the Plasmodium falciparum isolates from Kolkata
Authors: Acharya Alisha , Saha Pabitra , Chaudhury Abhijit , Guha Subhasish Kamal , Maji Ardhendu Kumar
Published: September 2024

Context:

Histidine-rich protein 2 (HRP2) detecting rapid diagnostic tests (RDTs) have played an important role in enabling prompt malaria diagnosis in remote locations. HRP2 has advantages over other biomarkers because of its abundance in the bloodstream, repetitive binding epitopes, and falciparum-specificity. Most HRP2-based RDTs also exhibit some cross-reactivity to a closely related protein (HRP3). Plasmodium falciparum parasites lacking HRP2 (pfhrp2) and 3 (pfhrp3) genes escape detection by these RDTs.

Objectives:

The objective of the study was to study the sensitivity and specificity of hrp2-based RDT for diagnosis of falciparum, to compare the RDT results with microscopy and polymerase chain reaction (PCR), and to determine the prevalence of HRP2 gene deletion among the RDT-negative, microscopy-positive falciparum strains.

Materials and Methods:

Blood samples were collected and diagnosis was done by microscopic examination, RDTs, and PCR.

Results:

Out of 1000 patients examined, 138 were positive for P. falciparum. Fever was the most common symptom followed by chills with rigor and headache were recorded among more than >95% of the study patients. Three microscopy-confirmed P. falciparum cases were negative by HRP2-based RDT and were found to have deletion of HRP2 and HRP3 exon 2.

Conclusions:

Rapid and accurate diagnosis and prompt deployment of effective antimalarial medication are essential components of appropriate case management. P. falciparum strains that evade diagnosis by RDTs represent a major threat to malaria control and elimination efforts.

Published: September 2024

Aims:

Severe acute respiratory syndrome-coronavirus-2 is a viral infection that was first discovered in Wuhan, Hubei province, China, in December 2019. Effects of COVID-19 infection could drastically influence other concomitant diseases like Malaria. Malaria and COVID-19 may mimic each other and share look-alike symptoms. The aim of this systematic review was to analyze the clinical and biochemical characteristics of malaria and COVID-19 synergism that was based on the published case reports.

Subjects and Methods:

An extensive literature search was carried out between May 2020 and February 2022 in PubMed, Google Scholar, and EMBASE. Our study was devised according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement.

Results:

We have evaluated 16 case reports and one case series of coinfection of malaria with COVID-19. It has been observed that all the patients showed lymphopenia, fever, headache (52%), vomiting (47%), cough (38%), chills (38%), body ache (38%), myalgia (28%), and sweating (14%). Despite unprecedented times, whenever there is a suspicion, we recommend that medical practitioners should be alert to presenting plethora features of COVID-19 and confirm with polymerase chain reaction test.

Conclusion:

We conclude that screening for COVID-19 should also be performed to mitigate missed diagnoses due to the long incubation period of novel coronavirus. Especially in vulnerable population, we should suspect other concurrent diseases and diagnoses in patients presenting with the symptoms of COVID-19 infection.

Published: September 2024

Context:

Toxoplasma gondii and rubella virus are microorganisms that can cause intrauterine infections and congenital anomalies in the fetus. Data regarding the simultaneous seroprevalence of these infections are not available in Senegal.

Aims:

This study aimed to determine for the first time the simultaneous seroprevalence of toxoplasmosis and rubella among pregnant women in Dakar.

Materials and Methods:

In this retrospective study, anti-Toxoplasma and anti-rubella antibodies were analyzed in the serum samples obtained from pregnant women receiving prenatal care at Military Hospital of Ouakam between 2016 and 2021 using a chemiluminescent microparticle immunoassay for the quantitative determination of immunoglobulin G (IgG) and IgM antibodies to Toxoplasma gondii and rubella in human serum.

Results:

Overall, data from 2589 women were analyzed. The median age was 29 years (interquartile range: 23.14–34.86). Serum IgG and IgM were positive for T. gondii with 35.84% and 1.66%, respectively. Rubella seroprevalence was 87.14% and 0.35%, respectively, for IgG and IgM. Seroprevalence of toxoplasmosis increases significantly with age and study period. For rubella infection, the highest seroprevalence rates were noted in the youngest age group and at the end of the study period.

Conclusions:

Data from this first-time study regarding simultaneous seroprevalence of toxoplasmosis and rubella among pregnant women in Senegal indicate a continuing high risk of congenital toxoplasmosis and congenital rubella syndrome in Dakar. Further studies are needed to fully assess the efficacy of rubella vaccination in women of childbearing age.

Published: September 2024

Immunocompromised patients with human immunodeficiency virus (HIV) infection are prone to multiple infections, of which parasitic infections are an important cause. Parasitic protozoal infections - both by common and rare protozoa are documented in such patients. Here, we report a rare and interesting case of five protozoal infections affecting a single HIV-infected person at the same time of initial presentation. A 64-years-male came to us with complaints of chronic diarrhea for 6 months. He was investigated and found to be positive for HIV I. His stool examination revealed cysts of Entameba histolytica and Giardia lamblia and oocysts of Cryptosporidium species and Cystoisospora species. His toxoplasma IgG was also positive in high titer. The patient was medically diagnosed and was treated with medications as clinically prescribed - antiretroviral therapy was initiated and he was discharged in due course. A total of five protozoal infections were documented affecting a single person - newly diagnosed immunocompromised male, which by sheer qualitative count of patient case histories, indeed is a rare case reported in the medical literature.

Authors: Kannambath Rachana , Rajkumari Nonika , Sivaradjy Monika
Published: September 2024

Background:

Battle against malaria has been going on since time immemorial. Understanding the true burden of disease and the determinants of its transmission are important for implementing adequate control measures. This study intends to explore the local epidemiology and burden of malaria in Puducherry, a coastal Union territory located in the Southern part of India over a period of 7 years.

Methodology:

A retrospective record-based study was conducted from 2015 to 2021, where details from all samples that tested positive for malaria by peripheral blood examination or rapid card test, from suspected cases were collected and analyzed.

Results:

The overall prevalence of malaria over the 7 years was 1.7% (257/14,888). Majority of the patients were male (75.88%) and the major age group affected was from 21 to 40 years (56.03%). The disease was maximum seen during the monsoon season followed by the post-monsoon season. Vivax malaria predominated irrespective of the gender, seasonal change, and different age groups except in children <10 years was both falciparum and vivax malaria were seen in equivalence. The major species to cause infection among infants were Plasmodium
falciparum (3/4).

Discussion and Conclusion:

This study shows a declining trend of malaria transmission over the years. There is no change in the predominant species affected or seasonal trends over the years. The possibility of underestimation of cases due to various factors cannot be ignored.

Authors: Patel Surbhi J. , Pathak Priya , Thejeswi Poornachandra , Bandari Manisha
Published: September 2024

Acute appendicitis secondary to amoebic infestation is a rare possibility, especially in endemic areas. If left untreated, significant postoperative morbidity and mortality can result from the spread of amoebic trophozoites and subsequent tissue reaction. Histopathological examination of the resected appendix with demonstration of invasion by the parasite is mandatory for establishing a diagnosis. Careful examination of the specimen is thus of paramount importance.

Validation of the Long-Term Difficulties Questionnaire-Youth Version as a Measure of Chronic Stress in Adolescents in Sri Lanka
Authors: Ponnamperuma Thyagi
Published: September 2024

Introduction:

As a validated stress questionnaire to assess ongoing adversities of adolescents in developing countries is not available, we developed a brief general checklist, the “Long-term Difficulties Questionnaire-Youth” version (LTD-Y) to measure daily stressors of adolescents and examine the psychometric properties of the instrument.

Methods:

In 2008, 755 schoolchildren in Sri Lanka (54% girls), age 12–16 years, completed a self-reported questionnaire with four sections. (1) demographic information (2) daily stressors and social support (3) trauma exposures measures; different trauma exposures and tsunami impact, (4) current psychological problem measures; posttraumatic stress symptoms, emotional and behavioral problems, functional impact, happiness at home, and happiness at school. In July 2009, a subsample of 90 adolescents repeated these measures. Internal consistency factor structure, concurrent validity, construct validity, and temporal stability were assessed in the scale.

Results:

LTD-Y adequately identified the ongoing adversities of adolescents. The scale showed an excellent internal consistency with Cronbach's alpha = 0.79. The principal component analysis showed two-factor solutions which concern “external” and “internal” stressors. The concurrent validity was indicated by its positive association with all measures of current psychological problems. The discriminant ability of the adversity measure was evident in cumulative trauma exposure and all variables with current psychological problems. The stability of reporting was satisfactory.

Conclusion:

This school-based screening showed that the LTD-Y has sufficient validity, competency, and stability in measuring ongoing adversities of adolescents.

Published: September 2024

Purbalingga Regency had achieved zero indigenous malaria cases in April 2016, 3 years before the targeted deadline for elimination. Currently, the biggest threat to elimination efforts is the risk of local malaria reintroduction due to imported cases in the receptive areas. The aim of this study was to describe the implementation of village level migration surveillance and identify the areas for improvement in it. We performed the study in four malaria-free focus villages in Purbalingga Regency, i.e., Pengadegan, Sidareja, Panusupan, and Rembang, from March to October 2019. A total of 108 participants were involved in the processes. Data on malaria vector species, community mobility from malaria-endemic areas, and implementation of malaria migration surveillance (MMS) were collected. We use descriptive analysis for quantitative data and thematic content for qualitative data. Socialization of migration surveillance in Pengadegan and Sidareja villages has been carried out to the wider community, whereas in Panusupan and Tunjungmuli villages, it is still limited to neighbors. Communities in Pengadegan and Sidareja villages have participated in reporting the arrivals of migrant workers, and the village malaria interpreter conducts blood tests on all migrants. Community participation in reporting migrant workers arriving in Panusupan and Tunjungmuli villages is still low. Recording of migrant data reporting has been carried out by MMS officers, but malaria checks are only carried out before Eid al-Fitr to prevent importation of malaria cases. The program needs to strengthen the community mobilization and case-finding efforts.

Published: September 2024

Работа посвящена задаче С.П. Новикова об описании геометрии линий уровня квазипериодических функций на плоскости. Рассматривается наиболее общий случай, когда число квазипериодов функции не ограничено. Главным предметом исследования является при этом появление открытых линий уровня либо замкнутых линий уровня сколь угодно больших размеров, играющих важную роль во многих динамических системах, связанных с задачей Новикова. Как можно показать, результаты, полученные здесь для квазипериодических функций на плоскости, обобщаются и на многомерный случай. В этом случае речь идет об обобщенной задаче Новикова, а именно о задаче описания поверхностей уровня квазипериодических функций в пространстве произвольной размерности. Как и задача Новикова на плоскости, обобщенная задача Новикова играет важную роль во многих системах, содержащих квазипериодические модуляции.

Топология пространств разориентаций
Authors: Ayzenberg Anton Andreyevich , Gugnin Dmitry Vladimirovich
Published: September 2024

Пусть $G_1$ и $G_2$ - две конечные подгруппы группы $\mathrm {SO}(3)$. Двусторонние факторы вида $X(G_1,G_2)=G_1\backslash\mathrm{SO}(3)/G_2$ были введены в материаловедении и называются пространствами разориентаций. В настоящей статье рассматриваются известные результаты, позволяющие описать топологию пространств разориентаций. Если пренебречь орбифолдной структурой, то все пространства разориентаций являются замкнутыми ориентируемыми топологическими $3$-многообразиями с конечными фундаментальными группами. В случае, когда $G_1$, $G_2$ - кристаллографические группы, вычислена фундаментальная группа $\pi _1(X(G_1,G_2))$ и применена теорема эллиптизации для описания самих пространств. Многие пространства разориентаций гомеоморфны $S^3$ в соответствии с теоремой Перельмана. Однако в статье явно описаны топологические типы некоторых пространств разориентаций без использования теоремы Перельмана. Классификация пространств разориентаций позволяет ввести новые структуры $n$-значных групп на многообразиях $S^3$ и $\mathbb R\mathrm P^3$. Наконец, исследована связь конкретного пространства разориентаций $X(D_2,D_2)$ с интегрируемыми динамическими системами и торической топологией.

Clinical significance of peripheral blood UL16 and DR-70 for the early diagnosis and prognostic evaluation of colorectal cancer
Authors: Zong Zhi-Ping , Wu Chen
Published: September 2024

BACKGROUND

Early diagnosis of colorectal cancer (CRC) is of great significance to improve the survival rate and quality of life of patients, but early diagnosis of CRC requires more sensitive techniques. Peripheral blood UL16-binding protein 2 (ULBP2) and human fibrinogen degradation products (DR-70) are the main indicators for the diagnosis of malignant tumors.

AIM

To assess ULBP2 and DR-70 potential for the early diagnosis and prognostic evaluation of CRC to provide a reference.

METHODS

This study involved 60 patients with early-stage CRC (CRC group), 50 patients with benign colorectal tumors (benign group), and 50 healthy patients (control group) enrolled at the Affiliated Hospital of Jiangnan University and Jiangsu Province Official Hospital between January, 2020 and January, 2022. ULBP2 and DR-70 levels in the blood were determined and differences among the three groups and early diagnostic values for CRC were determined. Patients with CRC were divided into the good prognosis and poor prognosis groups, and ULBP2 and DR-70 levels in the blood and diagnostic values were compared.

RESULTS

ULBP2 and DR-70 serum levels were significantly higher in the CRC group than in the control and benign groups (P < 0.05); however, no significant differences were observed between the benign and control groups (P > 0.05). Among the 60 patients with CRC followed up for two years, two died (3.33%) and 15 exhibited tumor metastasis, progression, or recurrence (25.00%). ULBP2 and DR-70 serum levels were significantly higher in the poor prognosis group than in the good prognosis group (P < 0.05). A receiver operating characteristic curve was plotted. Area under the curve, sensitivity, and specificity of serum ULBP2 with DR-70 for the early diagnosis of CRC were higher than those of the single serum indices (P < 0.05) in both the good and poor prognosis groups.

CONCLUSION

ULBP2 and DR-70 serum levels were significantly high in patients with early-stage CRC. They improved the diagnostic rate of early-stage CRC and predicted patient prognosis, thereby showing clinical application potential.
Prognostic value of PEA3 subfamily gene expression in cholangiocarcinoma
Authors: Wang Li , Zhang Zhe , Ma Hai-Zhang
Published: September 2024

BACKGROUND

Cholangiocarcinoma (CCA) is a lethal malignancy with limited treatment options and poor prognosis. The PEA3 subfamily of E26 transformation specific genes: ETV1 , ETV4 , and ETV5 are known to play significant roles in various cancers by influencing cell proliferation, invasion, and metastasis.

AIM

To analyze PEA3 subfamily gene expression levels in CCA and their correlation with clinical parameters to determine their prognostic value for CCA.

METHODS

The expression levels of PEA3 subfamily genes in pan-cancer and CCA data in the cancer genome atlas and genotype-tissue expression project databases were analyzed with R language software. Survival curve and receiver operating characteristic analyses were performed using the SurvMiner, Survival, and Procr language packages. The gene expression profiling interactive analysis 2.0 database was used to analyze the expression levels of PEA3 subfamily genes in different subtypes and stages of CCA. Web Gestalt was used to perform the gene ontology/ Kyoto encyclopedia of genes and genomes (GO/KEGG) analysis, and STRING database analysis was used to determine the genes and proteins related to PEA3 subfamily genes.

RESULTS

ETV1 , ETV4 , and ETV5 expression levels were significantly increased in CCA. There were significant differences in ETV1 , ETV4 , and ETV5 expression levels among the different subtypes of CCA, and predictive analysis revealed that only high ETV1 and ETV4 expression levels were significantly associated with shorter overall survival in patients with CCA. GO/KEGG analysis revealed that PEA3 subfamily genes were closely related to transcriptional misregulation in cancer. In vitro and in vivo experiments revealed that PEA3 silencing inhibited the invasion and metastasis of CCA cells.

CONCLUSION

The expression level of ETV4 may be a predictive biomarker of survival in patients with CCA.

This study is aimed at examining differences in self-esteem, positive body image and life satisfaction among the people at the sixth stage (Intimacy vs. Isolation) and the seventh stage (Generativity vs. Stagnation) of Erikson’s psychosocial development, with regards for gender. Also, the correlation between self-esteem, positive body image and life satisfaction was tested in the study. 309 adults, aged between 18 and 65 (M = 33.65, SD = 14.64), including 154 women (49.83%), participated in the cross-sectional online study. The total sample was spilt into two groups, regarding Erikson’s theory of psychosocial development: Stage 6 (early adulthood from 18 to 39, M = 24.20, SD = 6.15, n = 199) and Stage 7 (middle adulthood from 40 to 65, M = 50.76, SD = 8.85, n = 110). To measure life satisfaction, self-esteem and positive attitude towards the body, the Satisfaction With Life Scale (SWLS), the Rosenberg Self-Esteem Scale (SES), and the Body Appreciation Scale (BAS-2) were used respectively. Results indicate that middle-aged people are more satisfied with their life, and score higher in self-esteem and positive body image than young adults. Life satisfaction, self-esteem, and positive body image are correlated positively. Self-esteem and positive body image are predictors of life satisfaction and, together with gender and age, explain 48% of its variance in early- and middle-aged adults.

The study’s aim was to describe the sense of mothers’ responsibility for the child and their assessment of parental responsibility of the father and other people close to the child. It was also to determine the relationship of these variables with the Jennifer J. Senior’s concept of difficulties experienced in motherhood and parental burnout. The author’s Questionnaire of the Perceived Responsibility for the Child, the 2nd ver. of the „All Joy and No Fun” Questionnaire and The Parental Burnout Assessment (Polish version) were used. The study involved 99 mothers (aged 20–51; M = 33; SD = 6) of at least one child aged 1–10. A particularly high sense of parental responsibility of mothers was noted. The difference in the mother’s sense of parental responsibility and the responsibility attributed to the father correlated positively with both the difficulties experienced in motherhood and the symptoms of parental burnout.
Monolith: Circuit-Friendly Hash Functions with New Nonlinear Layers for Fast and Constant-Time Implementations
Authors: Grassi Lorenzo , Khovratovich Dmitry , Lüftenegger Reinhard , Rechberger Christian , Schofnegger Markus , Walch Roman
Published: September 2024

Hash functions are a crucial component in incrementally verifiable computation (IVC) protocols and applications. Among those, recursive SNARKs and folding schemes require hash functions to be both fast in native CPU computations and compact in algebraic descriptions (constraints). However, neither SHA-2/3 nor newer algebraic constructions, such as Poseidon, achieve both requirements. In this work we overcome this problem in several steps. First, for certain prime field domains we propose a new design strategy called Kintsugi, which explains how to construct nonlinear layers of high algebraic degree which allow fast native implementations and at the same time also an efficient circuit description for zeroknowledge applications. Then we suggest another layer, based on the Feistel Type-3 scheme, and prove wide trail bounds for its combination with an MDS matrix. We propose a new permutation design named Monolith to be used as a sponge or compression function. It is the first arithmetization-oriented function with a native performance comparable to SHA3-256. At the same time, it outperforms Poseidon in a circuit using the Merkle tree prover in the Plonky2 framework. Contrary to previously proposed designs, Monolith also allows for efficient constant-time native implementations which mitigates the risk of side-channel attacks.
Unsupervised Machine Learning-Driven Assessment of Infill Wall Systems for Structural Performance in Soft Stories
Authors: Rahman Taimur
Published: September 2024

Infill wall systems have been extensively studied as potential solutions to mitigate the adverse effects of stiffness irregularity in soft-storey structures. This research leverages unsupervised machine learning techniques, specifically clustering algorithms, to analyze and compare the mechanical behavior of different columns in a nine-storey unsymmetrical reinforced concrete building subjected to seismic loading. The primary objective is to assess the effectiveness of various infill wall systems, including 5-inch and 10-inch wide brick walls and 5-inch, 7.5-inch, and 10-inch wide concrete walls, in enhancing structural resilience. The study employs a comprehensive data-driven approach, incorporating ETABS modeling, data preprocessing, exploratory data analysis, and clustering to identify patterns and relationships in the structural performance of columns. Key findings indicate that more comprehensive and concrete infill walls significantly reduce displacement values, improving structural stiffness. Cluster analysis reveals that columns connected to multiple infill walls, particularly exterior corner columns, exhibit enhanced structural performance. Specifically, the 10-inch comprehensive concrete infill wall system demonstrated the highest efficacy in mitigating stiffness irregularity. The research further highlights that clustering algorithms, such as K-Means, effectively categorize columns based on their mechanical responses, facilitating a comparative evaluation of infill wall systems. These insights provide valuable recommendations for designing and retrofitting soft-storey structures to enhance seismic resilience.

Published: September 2024

Poverty is one of the crucial social problems in rural areas. The problem of poverty in rural areas is increasingly in the spotlight because of its broad impact on the community's economic and social sustainability. The varying levels of poverty require an appropriate analytical approach to design effective intervention programs. In an effort to understand and address this problem, this study uses the K-Means Clustering method to group the poor population. We use K-Means clustering to identify and group hamlets based on their poverty levels. This study aims to categorize the hamlets in Bandar Kumbul Village into multiple clusters according to their poverty levels, thereby identifying which hamlets necessitate more focused attention. The research methods used include collecting data on the number of poor people from 2013 to 2022 in each hamlet, data preprocessing, applying the Elbow method to determine the optimal number of clusters, and applying the K-Means Clustering algorithm to group the hamlets. The results of the study show that there are three main clusters with different characteristics. Cluster 0 includes Hutaimbaru and Mailil Julu hamlets with high poverty levels. Cluster 1 only includes the Pasir Sidimpuan hamlet, which has medium poverty levels. Cluster 2 includes Aek Mardomu, Bandar Kumbul, Mailil Jae, Sidodadi, and Singga Mata hamlets with low poverty levels. Variations in distance from the cluster center indicate significant differences in the distribution of poverty in each hamlet. The K-Means Clustering method is effective in identifying and grouping hamlets based on poverty levels, providing useful insights for the government and stakeholders to design more targeted intervention programs. Clusters with high poverty levels require immediate intervention, while clusters with medium and low poverty levels require maintenance and support to prevent an increase in poverty. This study provides a strong foundation for decision-making and policies to reduce poverty levels in Bandar Kumbul Village more effectively and sustainably.

Published: September 2024

Dalam sistem hukum Indonesia, penggunaan bahasa asing dalam pembuatan akta notaris merupakan isu yang kompleks dan signifikan. Notaris, sebagai pejabat umum yang berwenang, wajib menyusun akta dalam bahasa Indonesia sesuai dengan Undang-undang Jabatan Notaris No. 2 Tahun 2014 Pasal 43 dan Undang-Undang Nomor 24 Tahun 2009 tentang Bendera, Bahasa, dan Lambang Negara, serta Lagu Kebangsaan. Penelitian ini bertujuan untuk menganalisis rekognisi hukum terhadap penggunaan bahasa asing dalam akta notaris dan implikasinya terhadap keabsahan akta tersebut. Metode penelitian yang digunakan adalah yuridis normatif dengan pendekatan perundang-undangan dan studi kasus. Hasil penelitian menunjukkan bahwa meskipun terdapat ketentuan yang mengharuskan penggunaan bahasa Indonesia, masih terdapat keleluasaan dalam penggunaan bahasa asing dengan syarat akta tersebut diterjemahkan oleh penerjemah tersumpah dan dicantumkan bersama akta aslinya. Kesimpulan dari penelitian ini adalah bahwa rekognisi hukum terhadap penggunaan bahasa asing dalam akta notaris di Indonesia diatur secara ketat untuk memastikan kejelasan dan keabsahan dokumen hukum, serta untuk melindungi hak-hak pihak yang terlibat. Implikasi praktis dari temuan ini adalah perlunya notaris memastikan kepatuhan terhadap regulasi bahasa guna menghindari potensi sengketa hukum di kemudian hari

Developing Critical Thinking in Grades 3-4
Authors: Nalls Irdawati
Published: September 2024

This study aims to analyze the impact of high-stakes testing practices in Asian countries, particularly Singapore, on students' learning outcomes and overall intellectual development. While the education system that focuses on standardized testing has garnered international recognition, it also raises concerns about the dominance of rote memorization over the development of critical thinking skills. This research proposes integrating Bronfenbrenner's Ecological Systems Theory and Critical Theory in Education as a framework for curriculum design to create a more balanced educational approach. The research method employed was observational and participatory, conducted over one academic year in a 3rd and 4th-grade classroom in Singapore. Data were collected through classroom observations, student writing samples, and parental involvement in the writing program. Parental involvement included weekly writing facilitation sessions and providing insights into the influence of parents on student development. The results of the study indicate that high-stakes testing practices contribute to improved academic performance but tend to limit students' critical thinking abilities. The use of a holistic approach in the curriculum, emphasizing student engagement and environmental support, proved effective in fostering analytical thinking. The implications of this study highlight the need to balance test preparation with the development of critical thinking skills in the education system, ensuring that students not only excel academically but are also equipped to think critically and adapt to global contexts.
Practicing Islamic-Based Leadership
Authors: Sawalhi Rania , AlSaleh Amal , Khulief Jameelah
Published: September 2024

Although the literature offers various frameworks related to Islamic-based leadership, we argue that these frameworks have not fully encompassed all the preparations that Muslims must undertake for the afterlife. Al-Kaylani (1973–2015) is one of the Islamic philosophers who developed a relational model that connects individuals with the Creator, the universe, fellow human beings, life, and the afterlife. This qualitative study aims to explore the perspectives of Arab school leaders on the extent to which they apply Islamic-based leadership based on Al-Kaylani's relational model, as well as the factors influencing their practices. In this study, 13 school principals shared their perspectives and practices concerning what they refer to as Islamic schools and Islamic education within the Arab context. The findings reveal that the school leaders' understanding of Islamic education varies significantly based on their assumptions, influencing their practices and priorities in school planning and goals. Only one school leader attempted to align their practices with the afterlife. This study encourages researchers and practitioners to explore Al-Kaylani's model further and reimagine Islamic education's meaning in Muslim schools.
Sermons of Metropolitan Stefan Yavorsky on the Feasts of Russian Saints Peter and Alexius: Research and Publication
Authors: Попович А.И.
Published: September 2024

В статье систематизируются сведения о проповедях митр. Рязанского и Муромского Стефана (Яворского), посвященных российским святителям Петру, Алексию, Ионе и Филиппу. На примере двух проповедей (на день свт. Петра (1700‑е гг.) и день свт. Алексия (1707 г.)), опубликованных впервые в приложении к работе, рассматривается место этих сочинений в творческой биографии проповедника. Исследуется авторская работа над этими текстами, анализируется их идейное содержание, выявляются сквозные мотивы и риторические стратегии. Обращение к авторитету российских святителей позволяло митр. Стефану, с одной стороны, обличать грехи паствы, «бесовских плевел», из-за которых Россия переживает различные бедствия, а с другой — создать идеальный образ «доброго пастыря», заботящегося о вверенных ему овцах, и призвать слушателей к покаянию в грехах.

The study systematizes information on the sermons of Metropolitan of Ryazan and Murom Stefan Yavorsky, dedicated to the Russian saints Peter, Alexius, Jonah, and Philip. Using just two of his sermons (on the day of St. Peter (1700s) and the day of St. Alexius (1707)) published for the first time in the appendix below, the article explores the place of these works in the preacher’s creative activities. The article examines the work process on these texts, analyzes their ideological content, identifies cross-cutting motifs, and rhetorical strategies. Relying on the authority of the Russian holy hierarchs allowed Metropolitan Stefan, on the one hand, to expose the sins of his flock (“demons’ tares”) which cause various disasters in Russia; and on the other hand, this allowed him to create an ideal image of a “good shepherd” who takes care of the sheep entrusted to him, and to call his listeners to repent of their sins.
