Authors: Mary Vincy T , Vengatesan Ramya , Rajasekaran Vallabi
Published: March 2024

Background:

Cervical carcinoma ranks as the fourth most prevalent cancer in women worldwide, following breast, colorectal, and lung cancers. Screening is a crucial secondary prevention strategy, particularly in developing nations such as India, ensuring effective prevention and treatment. This study investigates the micronuclei assay in urothelial cells as a potential biomarker for cervical carcinoma screening, focusing on its correlation with colposcopic and histopathological observations.

Materials and Methods:

The prospective study was conducted from September 2016 to September 2017 at the Department of Pathology, Institute of Obstetrics and Gynecology, Madras Medical College, Chennai, Tamil Nadu, India. It involved 108 women who visited the colposcopic clinic. Urine samples were collected from 50 women with normal colposcopic findings and 58 with abnormal colposcopy results. Micronuclei scoring was performed on 1000 epithelial cells from the smears. Additionally, cervical biopsies were conducted for the 58 cases with abnormal colposcopic findings, and the resulting histopathological data were juxtaposed with the findings of the micronuclei assay.

Results:

The study’s findings demonstrated a sensitivity of 82.76% and a specificity of 90%, with positive predictive values of 90.75% and negative predictive values of 81.82%. Additionally, a statistically significant linear correlation was observed between the micronuclei assay and histopathological diagnosis, with a P value of less than 0.001.

Conclusion:

Therefore, the micronuclei assay offers a means to detect genotoxicity, monitor cervical carcinogenesis, and identify high-risk groups using simple, reliable, and cost-effective techniques suitable for large-scale screening programs.

Authors: Deshmukh Kunal , Shetiya Sahana Hegde , Mathur Anmol
Published: March 2024

Aims and Objectives:

The present study assessed the knowledge, perceptions, and behaviors related to tobacco use surveillance among both teaching and nonteaching staff members before and after implementing the “Tobacco Free School” intervention. This initiative targeted establishing tobacco-free environments, specifically in Marathi medium-high schools within the Pimpri-Chinchwad Municipal Corporation, Pune District, Maharashtra, India.

Materials and Methods:

Data for the serial cross-sectional study were gathered using a validated questionnaire administered to teaching and nonteaching staff members at these schools at baseline and follow-up. The intervention was conducted in three schools between June 2019 and September 2020. The number and percentage for each question concerning knowledge, perception, and practice were calculated with a confidence interval of 95% and a P value of <0.05 considered significant. The McNemar test was employed to assess whether there was a significant difference between pre- and post-study results.

Results and Discussion:

Ninety percent of teachers demonstrated awareness of the law. Familiarity with two specific sections of Cigarettes and Other Tobacco Products Act 2003: Sections 4 and 6 showed a 39% difference in knowledge acquired between pre- and post-study results. Staff members were better aware of the tobacco vendors setting up shop outside the educational institution post-survey (P = 0.03).

Conclusion:

Staff members learned about tobacco products’ content, ill effects, and better-perceived tobacco control. Based on the respondent’s reply (61%) on the presence of tobacco vendors within 100 yards, the offending vendor’s picture was uploaded on the “Tobacco Monitor App” so that prompt action could be initiated by the State Tobacco Control Cell.

Authors: Borse Manasi , Mullerpatan Rajani , Tawade Shubham , Agarwal Bela
Published: March 2024

Background:

Sitting and rising from the floor significantly predict all-cause mortality. The increasing life span of older people and the need to maintain physical fitness and independent functioning necessitate engaging in different forms of habitual physical activity. This study explored the influence of chronic exposure to floor sitting on spatial-temporal variables of sitting from the floor and factors influencing older people’s ability to rise.

Materials and Methods:

Following approval from the Institutional Ethical Committee, spatial-temporal variables of sitting from the floor were measured in 120 community-dwelling healthy elderly (age 60–85 years, male-to-female ratio—1:1 and urban-to-rural ratio—1:1) Exposure to floor-level activities was recorded using MGM Ground Level Activity Exposure questionnaire. The International Physical Activity Questionnaire was used to measure health-related physical activity. The sitting-rising test was captured using a digital camera. Ascent and descent times were computed, and the motor strategy used to act was recorded. Muscle strength of the lower extremity (Chair Raise Test), cardio-respiratory endurance (Six-Minute Walk Test), and balance (Berg Balance Test and Floor Square Step Test) were evaluated.

Results:

Urban people reported lower exposure to floor sitting [12.6 (16.2)] min/day (P = 0.000) compared with rural people [211.0 (76.9)] min/day (P = 0.000). Ascent time and descent time were more significant in urban people [42.6 (36.3)] min/day (P = 0.000) and 42.2 (30.7) min/day (P = 0.000) compared with rural people [20.0(10.4)] min/day and [21.3(13.7)] min/day (P < 0.05). Males required shorter activity time than females (P < 0.05). There was a moderate negative correlation between chronic daily exposure to cross-leg sitting and ascent time (Spearman’s rho = -0.407; P = 0.000) and descent time (Spearman’s rho = -0.409; P = 0.000), and moderate positive co-relation between daily cross-leg sitting exposure and cardio-respiratory exposure (Spearman’s rho = 528; P = 0.000), balance (Spearman’s rho = 371; P = 0.000), and muscle strength of lower extremity (Spearman’s rho = 632; P = 0.000).

Discussion:

Increases in the use of lower limb crossing during commencement, decreases in the use of hand support, and falls in the use of trunk rotations with lateral flexion throughout descent and ascent were all observed in those who had more daily habitual exposure to rising from the floor. People with less frequent exposure to rising from the floor in their daily routines showed the opposite tendency.

Conclusion:

Daily physical activity, including chronic exposure to rising from the floor, was observed to positively influence spatiotemporal variables, muscle strength of lower extremities, cardio-respiratory endurance, and balance. Factors influencing rising from the bottom need to be addressed by therapeutic interventions for maintaining the satisfactory functioning of older adults.

Authors: Sharma Monika , Singh Amrinder , Shenoy Shweta
Published: March 2024

Background:

The penalty corner stands out as a crucial scoring method in field hockey, with the Drag flick (DF) being the most frequently employed shot during this situation. The DF is more effective than the hit or push techniques.

Purpose:

This study aimed to explore variations in hip and ankle kinematics during different stages of the DF among field hockey players at national and university levels.

Materials and Methods:

The study adopted a cross-sectional design involving participation from professional male drag flickers, as well as national and university-level (UL) players, with reported mean ± SD values for height (172 ± 1.41 cm), weight (72.5 ± 2.12 kg), and BMI (24.4 ± 0.35 kg/m2). Following a specific warm-up, each player underwent the random recording of 10 trials on the hockey ground. XSENS inertial measuring unit was employed to acquire and analyze kinematics data. Thirty frames were extracted, spanning the DF technique’s initial phase to the final phase for subsequent analysis.

Results:

The findings revealed distinct variations in joint angle (XZY) range of motion (ROM) during different phases of the DF among national and UL players. Notably, significant (P < 0.05) and diverse changes were identified in various parameters of lower limb kinematics when comparing DF shots.

Conclusion:

The study’s conclusion emphasizes that comprehending the ROM variations in hockey players is crucial for sports scientists and coaches. NL and UL players showed different movement patterns in the same DF technique but at different extents. This knowledge enables them to understand the biomechanical responses necessary to attain optimal movement, mainly when aiming for the goal. It allows for a focused analysis of individual player movement patterns.

Published: March 2024

Background:

We aim to share our preliminary encounter with robotic knee replacements in Indian patients, focusing on the initial 100 cases. This report will delve into our observations regarding the learning curve and provide insights from a short-term follow-up at 6 months.

Materials and Methods:

Following institutional ethical clearance, we conducted an observational study involving 100 robotic-assisted total knee replacement cases performed from March 2022 to November 2022. These patients underwent a 6-month follow-up to evaluate functional outcomes. Our primary objective was to investigate the learning curve associated with robotic-assisted total knee arthroplasty (RATKA), specifically emphasizing operative time. Furthermore, we examined preoperative and postoperative alignment parameters as part of our analysis.

Results:

In our investigation, participants had a mean age of 64.68 years, with a female-to-male ratio of 43:22 and an average body mass index of 30.71 ± 4.88. Intraoperative blood loss was recorded at an average of 91.81 ± 21.63 mL. The mean surgical duration for the initial 25 cases was 102.5 ± 11.08 min, which improved to 65.65 ± 13.07 min for the subsequent 75 cases. The average hospital stay length was 2.88 ± 0.88 days. Notably, there was a significant enhancement in the Knee Society Score (KSS), with a preoperative mean of 38.90 ± 12.72 improving to a postoperative mean of 84.89 ± 4.10 (P = 0.001), as well as in the Oxford Knee Score (OKS), which saw a rise from 16.62 ± 16.42 preoperatively to 45.58 ± 4.97 postoperatively (P = 0.001). The accuracy of preoperative determination for femoral component sizes was 100%, while for tibial component sizing, it was 97%.

Conclusion:

The key finding from this observational study suggests that around 25 procedures are required to reach a learning plateau. During this process, an average decrease of 36.1 min in surgical time was observed from the initial to proficient stages. Notably, no learning curve was observed for lower limb alignment and implant placement, and no significant complication rates were documented.
Comparative study of sickling test, solubility test, and hemoglobin electrophoresis in sickle cell anemia
Authors: Nigam Rashi , Sharda Bela , Varma Amit V
Published: March 2024

Background:

Madhya Pradesh, a state in India, bears the highest number of sickle cell anemia (SCA) cases, particularly among its tribal communities. The diagnosis of suspected SCA cases involves utilizing several methods. The sickling test operates on the principle of hemoglobin S (HbS) polymerization upon deoxygenation. By contrast, the solubility test involves the reduction of HbS using sodium hydrosulfite, followed by precipitation of lysed red blood cells. Hemoglobin (Hb) electrophoresis identifies Hb variants based on their migration in an electric field. Our objective was to assess the efficacy of sickling and solubility tests as screening tools for detecting SCA, comparing them against capillary Hb electrophoresis, which is considered the gold standard.

Materials and Methods:

All individuals suspected of having SCA between 2022 and 2023 were enrolled in the study. Clinical information, peripheral blood smear analysis, sickling test, solubility test, and capillary Hb electrophoresis were conducted, and the results were compared.

Results:

Of 250 cases assessed, Hb electrophoresis identified 225 cases of SCA, resulting in a sickle cell disease to sickle cell trait (SCT) ratio of 1:1.36 and a male-to-female ratio of 1:1.33. The highest number of cases were observed in the age group from 21 to 30 years. Generalized weakness (77%) and abdominal pain (52%) were the most frequently reported symptoms. The sickling test demonstrated a sensitivity, specificity, and diagnostic accuracy of 91.5%, 72%, and 89%, respectively, compared with Hb electrophoresis. The solubility test yielded values of 76.5%, 68%, and 75% for sensitivity, specificity, and diagnostic accuracy, while peripheral smear analysis showed 36%, 25%, and 42%, respectively.

Conclusion:

The sickling test displayed superior sensitivity and diagnostic accuracy compared with the solubility test, with no significant disparity in specificity between these two methods. Notably, the solubility test exhibited a higher incidence of false-negative results for SCT. Therefore, the sickling test is the preferred screening method for SCA.

Authors: Palaha Harvinder , Pathak Sweety , Patil Sarita
Published: March 2024

Background:

Newborns represent the most vulnerable segment of our society, constituting nearly 30% of all under-5 mortality cases. Despite well-established healthcare systems in metropolitan areas, urban slum dwellers, comprising approximately 50%–60% of the population, often lack access to these services. The Society for Nutrition, Education, and Health Action (SNEHA) operates within urban slums, aiming to enhance health outcomes for mothers and children. At SNEHA, we firmly believe that a healthy society starts with the well-being of mothers and infants. Our organization is dedicated to empowering communities to improve the health status of newborns in urban slums.

Material and Methods:

As part of the intervention, 7819 households with a population of 35,000 were targeted. SNEHA’s field workers conducted regular visits to these households, providing counseling on breastfeeding immunization and identifying potential health risks. Married women of reproductive age were specifically identified and consistently educated about the significance of early pregnancy registration. Pregnant women received support for registering their pregnancies, attending regular antenatal care (ANC) check-ups, adhering to ANC visit schedules, and maintaining adequate iron, calcium, and nutrition intake. Additionally, they were informed about the advantages of institutional delivery and encouraged to prepare for childbirth. Mothers of children under 2 years were urged to bring them to primary health centers for routine immunizations. Furthermore, they were advised on contraception methods to ensure proper spacing between children.

Results:

Our endeavors have resulted in a 34% rise in early pregnancy registration, a 22% increase in the number of women attending four antenatal check-ups, an 11% uptick in institutional deliveries, a 24% improvement in exclusive breastfeeding rates, and a notable 67% surge in the prevalence of contraception.

Conclusion:

Our intervention has proven that it is possible to improve the health indicators of women and children through behavior change communication, regular home visits, and community awareness.

Published: March 2024

Purpose:

The objective of this study was to evaluate the prevalence of premalignant and malignant lesions in patients clinically diagnosed with pterygium who underwent excision procedures performed by 1st-year residents in ophthalmology at a teaching hospital between 2018 and 2021.

Methods:

A cross-sectional analysis was conducted on 274 medical records of patients diagnosed with pterygium who underwent excision procedures from 2018 to 2021 at Hospital PUC-Campinas in Campinas, São Paulo, Brazil. Fifty-four medical records were excluded due to missing essential data. Among the 220 records included for analysis, 239 histopathological results were considered, as 19 patients underwent pterygium excision in both eyes.

Results:

Out of 239 histopathological results analyzed, 236 (98.74%) were compatible with pterygium, 2 (0.8%) with epithelial dysplasia, and 1 (0.4%) with actinic keratosis.

Conclusion:

A histopathological study is essential for the accurate differential diagnosis of pterygium. Although the frequency of ocular surface squamous neoplasia is low, premalignant and malignant lesions must be ruled out. Correct diagnosis must be made to allow proper follow-up of the patients and prevent life-threatening lesions.

Published: March 2024

Introduction:

Parkinson’s disease, a neurodegenerative disease, involves motor and nonmotor components. Vision, a nonmotor component, has been studied by the analysis of the retinal layers by optical coherence tomography (OCT), and the main finding is the thinning of the retinal nerve fiber layer (RNFL). The aim of this study was to verify the influence of age on the thickness of retinal nerve fiber in patients with mild-to-moderate stages of Parkinson’s disease.

Materials and Methods:

Healthy individuals and patients with Parkinson’s disease were included in this prospective, cross-sectional, and observational study. The patients were recruited according to the clinical criteria from the neurology clinic of two major hospitals, with the description of the Hoehn and Yahr scale score. Healthy subjects were recruited from the general clinic and hospital staff. A comprehensive ophthalmic examination was performed previously on the spectral-domain OCT.

Results:

There was a significant effect of age in the thickness of the RNFL in patients with Parkinson’s disease, in the right eye in the lower quadrant (P = 0.026) and in the left eye in the upper (P = 0.029) and temporal (P = 0.037) quadrants, as well in the control group in the upper (P = 0.003) and lower quadrant (P = 0.024).

Conclusions:

This case series could demonstrate that in mild-to-moderate stages of the Hoehn and Yahr Scale, there is an asymmetric correlation between aging and the decrease in superior, inferior, and temporal RNFL between the eyes of patients with Parkinson’s disease, and this finding precedes the decrease in visual acuity.

Authors: Prabowo Agung , Cahyandari Rini , Abdul Halim Nurfadhlina
Published: March 2024

This research discusses the role of media conglomerates in the context of migration policies from analog to digital broadcasts. Media conglomerates often have great influence in the media industry, and migration policies such as these can affect the way information is delivered and accessed by the public. This research analyzes the tendency of media conglomerates to report information that suits their interests, their impact on society, and how they respond to digital migration policies. The political economy of communication theory, especially the concepts of commodification, spatialization, and structuration, is used to explain these dynamics. Some media conglomerates reject the migration policy, considering it a threat to their dominance in the media industry. However, migration policies also open up opportunities for new entrants in the broadcasting industry. In conclusion, it is important to understand how the dynamics of the political economy of the media influence media policies that affect society.
A study of growth of COVID-19 with super-spreaders using the modified SIR model including iceberg phenomenon
Authors: Gurpreet Singh Tuteja  , Lal Tapshi
Published: March 2024

This paper explores the dynamics of COVID-19 transmission, particularly focusing on super-spreaders, through the lens of the SIR model. The model comprises six compartments representing susceptible, exposed, symptomatic infected, super-spreader, asymptomatic infected, and recovered individuals. Utilizing a set of non-linear, interdependent differential equations, we numerically solve for model parameters to examine the influence of super-spreaders on infection spread within the population. We calculate the basic reproduction number (R0) and discuss the stability of disease-free equilibrium. Our findings underscore the significant role played by super-spreaders and asymptomatic individuals in disease dissemination. Drawing on the epidemiological concept of the iceberg phenomenon, we offer insights into super-spreader events (SSEs) in India and their ramifications.

Authors: Hashem Abd Al-Rahim , Al-Zaidy Aiad
Published: March 2024

The tectonic development of the Mesopotamia basin in southern Iraq was studied by calculating subsidence and sedimentation rates for eleven wells distributed over the study area. This was done by calculating backstripping for the Upper Campanian-Maastrichtian sequence. The subsidence rates increased in the south of the region near the Su-4, Su-1, and Lu-2 wells in the Hartha Formation, while the basin of the Shiranish Formation appeared to increase towards the northwest near the Ns-2 well. Then, the subsidence rates in the next formation, Tayarat, increase towards the south, near the wells. Su-1, Su-4, Lu-2. The Hartha Basin was divided into two tectonic parts based on the above. The Shiranish Basin was affected by uplift from the northeast and southeast directions, and due to this, an extremely shallow basin formed with its northern portion exposed during the transgression. At the end of this period, it became the regression stage, where the tectonic uplift began to decrease towards the southwest, and this indicates that the tectonic movement's reactivation due to continental collision, which is evident in the next stage with the deposition of the Alaiji Formation. According to these stratigraphic features, the studied area was divided into two tectonic basins, the northeast basin (Samawa-Nasiriya Subzone) and the southwest basin (Zubair Subzone) separated by tectonic lineament extending from Nasiriya-West Qurna and Zubair oil fields.

Authors: Ahmed Mohamed , Araffa Sultan , Hamed Tarek , Rabeh Taha , Helaly Ahmed , Farag Karam
Published: March 2024

Nine Magnetotelluric stations and 198 Land-Magnetic points were conducted within reclamation regions at the western and southwestern areas of the New Sphinx City, Egypt. The main target is to explore the deep groundwater aquifer (Nubian Aquifer), and its reserves. This was interpreted with integrated data available from thirteen water wells within the studied area. Their depths range from 160 to 773 m. We noticed that the wells don’t reach the Nubian Aquifer and the groundwater in the area comes from the Jurassic-Lower Cretaceous, the Upper Cretaceous-Eocene Limestone, and the Oligo-Miocene aquifers, which contain brackish/saline water. The groundwater table ranges between 128-170 m from the topographic-controlled ground surface. Structurally, the area is dissected by two major thrust faults trending in the NE-SW direction, while there is one major normal fault trending in the NW-SE direction. The results showed that the basement relief ranges between -2250 to -4650 m below mean sea level. The Nubian Aquifer extends through the central region within the area according to the results of Nine Magnetotelluric data. It is bounded by the two inverted faults within the Kattaniya inverted basin which is gradually thinning in the southward direction to disappear completely at the Gindi basin. It is partitioned into two units; the upper one was found at an average depth range between -1760 to -2245 m with an average thickness of about 485 m, while the lower unit depth ranges between -2800 to -3825 m with an average thickness of about 1025 m.

Authors: Mehdipour Vali , Kadkhodaie Ali , Awadh Salih
Published: March 2024

Integrated reservoir rock typing in carbonate reservoirs is a significant step in reservoir modelling. The key purpose of this study is the identification of integrated rock types in the Sarvak Formation of an Iranian oilfield. In this study, electrofacies (EFAC) analysis of the Sarvak reservoir was done in detail to determine the reservoir quality and rock types of the Sarvak Formation in the studied field. The core data and conventional petrophysical logs were used for rock typing. Some petrophysical logs such as porosity, sonic, neutron, density, and Photo electric factor were applied as input data for electrofacies analysis. Multi-Resolution Graph-Based Clustering was used among six approaches, resulting in four electrofacies after merging similar clusters. EFAC-1 has the lowest porosity, and EFAC-4 has the highest porosity. In addition, based on Winland and Amaefule approaches, three rock types were determined using core data (porosity and permeability). As a result, three rock types were defined; rock type-1 has the smallest pore-throat size and flow zone indicator while rock type-3 has the highest ones. The correlation coefficient between permeability and porosity in each rock type is more than 80%. Rock type 1 is mainly composed of EFAC-1 and EFAC-2, while rock types 2 and 3 share mostly the EFACs 1, 3 and 4.
Permeability Prediction and Facies Distribution for Yamama Reservoir in Faihaa Oil Field: Role of Machine Learning and Cluster Analysis Approach
Authors: Amer Manar , Al-Obaidi Dahlia
Published: March 2024

Empirical and statistical methodologies have been established to acquire accurate permeability identification and reservoir characterization, based on the rock type and reservoir performance. The identification of rock facies is usually done by either using core analysis to visually interpret lithofacies or indirectly based on well-log data. The use of well-log data for traditional facies prediction is characterized by uncertainties and can be time-consuming, particularly when working with large datasets. Thus, Machine Learning can be used to predict patterns more efficiently when applied to large data. Taking into account the electrofacies distribution, this work was conducted to predict permeability for the four wells, FH1, FH2, FH3, and FH19 from the Yamama reservoir in the Faihaa Oil Field, southern Iraq. The framework includes: calculating permeability for uncored wells using the classical method and FZI method. Topological mapping of input space into clusters is achieved using the self-organizing map (SOM), as an unsupervised machine-learning technique. By leveraging data obtained from the four wells, the SOM is effectively employed to forecast the count of electrofacies present within the reservoir. According to the findings, the permeability calculated using the classical method that relies exclusively on porosity is not close enough to the actual values because of the heterogeneity of carbonate reservoirs. Using the FZI method, in contrast, displays more real values and offers the best correlation coefficient. Then, the SOM model and cluster analysis reveal the existence of five distinct groups.

Authors: Tawfeeq Yahya , Al-Mufarji Mahmood , Abdul Aziz Qahtan
Published: March 2024

Changes to certain geophysical characteristics, such as sonic transit time with depth, indicate the pressure system of over-pressured zones. In this study, well-log data is used to investigate the distribution of formation overpressures in the tertiary reservoirs of one Iraqi oil field. Three wells located within the tertiary carbonate reservoir of one Iraqi oil field are of interest in this study. To assess the reservoirs, a petrophysics log analysis was carried out. The reservoir's intervals are the area of interest. The sonic velocity data was used to create a normal compaction trend line, and the overpressure zones were identified by observing the reversals in the normal compaction trend line. The pore pressure, fracture pressure, and gradients were calculated using the Eaton method. The method relies on the correlation between the normal transit time found on the normal compaction trend and the observed transit time from the log reading. The sonic log determines the bulk density and matches the density derived from the density log. Abnormal pressures were identified primarily within the area of interest, especially with unit B in Well 1. In Well 2, the abnormal pressures were recognized in zones above the area of interest. Abnormal pressures in Well 3 were identified primarily within all areas of interest. The importance of this work is to help predict overpressure zones in the research area before drilling or workover.
Investigating the Bubble Point Pressure Discrepancy by History Matching for Mishrif Reservoir, Southern Iraqi Oil Field
Authors: Al-Rikaby Alaa , Al-Jawad Mohammed
Published: March 2024

Carbonate reservoirs have been a primary focus for academics and oil and gas companies for many years. However, the complex nature of these rocks has always posed challenges. This is particularly true in the study area, which is located in the unstable Mesopotamian Basin, where multiple oil fields produce hydrocarbons from NW-SE-trending anticlines along the Zagros Fold-Thrust Belt. The primary goal of reservoir simulation is to forecast reservoir performance and apply different techniques to improve hydrocarbon recovery under different conditions. The study area faces a problem of discrepancy in the bubble pressure at the same reservoir unit, which is attributed to the faults in the Mishrif reservoir. A study was conducted to investigate the causes of this phenomenon. The proposed method for verification involves simulating history matching using the Petrel platform after building two geological models on the probability of the fault and the reef; as a result of seismic survey interpretation. Field data for gas production of the reservoir and Pressure-Volume-Temperature analyses, especially the wells (well pad F), were used to determine the causes of the discrepancy. The current study found that the calculated and observed data match more consistently in the case of the fault rather than in the case of the reef, indicating the presence of fault in the area near the well pad F. This caused compartmentalization, leading to the discrepancy in the bubble pressure. This study could significantly improve regional exploration, especially in Iraq.

This research aims to see the extent of the contribution of parents' professions to the formation of students' religious character at Madrasah Ibtidaiyah Nizamul Islam Probolinggo. Because currently there are more and more phenomena showing that parents have various professions but often forget about the educational process which has implications for the formation of religious character. A qualitative approach is used by researchers because it explores information naturally from phenomena that occur in the field. Data collection was obtained through interviews with informants and Miles & Huberman data analysis was carried out which included three activity streams, namely data reduction, data presentation and drawing conclusions. The conclusions from this research show that parents' professions have a huge impact on the formation of students' religious character. The religious character possessed by students is formed from the example of parents in carrying out daily Islamic teachings, familiarizing themselves with morals, and providing educational rewards for children, thereby creating motivation to always do good.

Let G be a ﬁnite simple graph with Laplacian polynomial ψ(G,λ) = ∑ k=0n(−1)n−kck(G)λk. In an earlier paper, we computed the coeﬃcient of cn−4 for trees with respect to some degree-based graph invariant. The aim of this paper is to continue this work by giving an exact formula for the coeﬃcient cn−5 in the polynomial ψ(G,λ). As a consequence of this work, the Laplacian coeﬃcients cn−k, k = 2, 3, 4, 5, for some know trees were computed.

Published: March 2024

The limited availability of land in major cities like DKI Jakarta, Surabaya, and Denpasar City has forced residents to compromise on ideal settlement locations, leading to a switch in land use patterns. Failure to secure ideal locations exacerbates settlement issues, ultimately contributing to the proliferation of urban slums. Denpasar City, in particular, grapples with various problems stemming from slum growth. As part of its responsibilities in urban development, the government is tasked with providing public services, safeguarding low-income communities, promoting regional growth, ensuring environmental sustainability, and upholding national integrity. However, the phenomenon of migrant influx in Denpasar City presents an additional challenge for governance. Traditional villages play a pivotal role in managing migrant populations by leveraging pecalang (traditional Balinese security forces) and customary rules to maintain community cohesion. To effectively address slum proliferation, customary villages must align their development goals and strategies. This qualitative research utilizes primary and secondary data to explore the role of institutions in slum management. Despite various programs aimed at mitigating urban challenges, the effectiveness of institutions like the PKP Working Group and DLHK remains suboptimal. Therefore, there is a pressing need for customary villages to play a more active role in tackling slum issues within their jurisdictions.

Dysmenorrhea is the term used to describe lower abdominal pain that women feel during their menstrual cycle. Teens suffering from menstrual pain typically have lower abdominal cramps and other symptoms that interfere with day-to-day activities. An alternative to medication for treating menstruation discomfort is yoga. This study aimed to ascertain whether yoga may lessen dysmenorrhea in teenagers enrolled in school. This approach uses the MEDLINE/PubMed, Scopus, and Google Scholar databases to review literature. The PRISMA approach utilized for this literature review was adhered to during the article selection process. The research's selection criteria comprised works published within the last five years, specifically from 2018 to 2023. Yoga was employed to lessen dysmenorrhea discomfort in the research population, consisting of young women with monthly pain. Between 2018 and 2023, 666 studies were discovered to have satisfied the publication selection requirements. Fifteen journals that fit the requirements for this study were identified through the PRISMA route search. According to the data, yoga has been shown to have a calming effect on teenage menstrual discomfort in 15 journals. Thus, yoga is a successful non-pharmacological management strategy for lowering dysmenorrhea in school-age teenagers. This is because yoga may be calming, encouraging the body to release endorphins, which function as organic painkillers. Yoga is a mild activity that helps the body avoid stiffness, pressure, pain, and tiredness while increasing flexibility safely. It enhances lung capacity when breathing, improves blood circulation, eases physical and emotional stress, and lessens pain. Additionally, practising yoga helps women with PMS feel more at ease by reducing dangerous inflammatory secretions.
