PENGENALAN MATEMATIKA REALISTIK BAGI ANAK KELAS VIII DI MTSN 2 MEDAN
Authors: Hidayat M. Arif , Rahmi Sofia 
Published: August 2023

<p>MTSN 2 Medan merupakan salah satu madrasah unggulan di kota Medan. MTSN 2 Kelas VIII merupakan tempat kegiatan masyarakat. Siswa yang belajar di sekolah ini masih cenderung menghafal konsep/prinsip yang harus dipelajarinya. Sebagian besar siswa hanya belajar matematika sampai sekolah menengah, sehingga menyelesaikan masalah matematika sangat sulit. Siswa juga tidak tertarik dengan fenomena matematika di sekitarnya. Di Kelas VIII MTSN 2 sendiri, salah satu kesulitan dalam pembelajaran matematika adalah lemahnya kemampuan siswa dalam menerapkan materi matematika dalam kehidupan nyata. Guru tidak memberikan kesempatan kepada siswa untuk mencari ide-ide yang biasanya melayang di kepala mereka. Siswa hanya fokus pada satu sumber dan tidak mencari jawaban dari masalah, biasanya mereka memiliki kepercayaan diri yang rendah terhadap masalah yang diberikan. Beberapa kriteria dalam pengembangan pembelajaran matematika bertujuan untuk membuat matematisasi pengalaman sehari-hari. Alternatif yang baik untuk belajar matematika adalah belajar matematika realistis. Matematika realistik adalah matematika sekolah yang dilaksanakan dengan mengambil realita dan pengalaman siswa sebagai titik tolak pembelajaran. </p>
Environmental Politics in Authoritarian Regimes: Waste Management in Russian Regions

Published: August 2023

Abstract
Russian regions exhibit significant variation in their waste management efforts, despite the urgency of the problem and the importance of waste management for all regional governments. To examine this variation, we apply the concept of authoritarian environmentalism, which suggests that authoritarian governments have distinctive capabilities for tackling certain environmental challenges. Analysis of a regional panel data set for the period 2012-2019 shows that our measure of the degree of authoritarianism – the share of votes for the ruling party United Russia in parliamentary elections – has a strong positive effect on the share of recycled waste in the Russian regions. This result indicates that more authoritarian regions tend to recycle more household waste than less authoritarian regions. However, it could also be the case that more authoritarian governments are simply more likely to manipulate their environmental statistics to show better environmental performance.

Background; Futile care; a medical term applied when there is no reasonable hope of improvement or cure in spite of expense of medical or surgical care. Futile care decision governed by a variety of scoring systems to evaluate clinical situation and direct medical effort in respecting the patient requirement, surrogate allowance. Where and when the medical treatment being futile is another view must be sought for afflicted patient.
Materials & methods; This is a retrospective study about admitted patient over 7 years (since January 2012-until December 2018) were 2076 patient (total admission number) in Kirkuk teaching hospital burn unit, of them (1284 female, 762 male burns casualty) 74% of them are saved but (26%) 538 patient are dead out of total number of admission , (21%) 435 patient were with expected death, but (5%) 103 {(79 pediatric less than 12 years) and (24 patient age more than 56 years)} with un expected death the latter were succumbed to sepsis even with our best available rescue management.
Result; This study on those (21%) 435 patients (with more than 55% BSAB. & mostly associated with inhalational injury) sex variation{23 male (25-55 years) , 412 female (13-45years)}most of them self-immolation; who are falls under the known guide lines {DNR=Do Not Resuscitate} comfort care applied to them, we depend on R-Baux score to predict the probability of death after burn injury was calculated for each patient by following formula:
(TBSA + age + [17×R]). {R=1 if patient has inhalation injury and R=0 if not}.
Aim; of our study is to evaluating our working in spite of our challenges in Iraq circumstances.
we used different formulae to predict mortality in burn casualties to reach best results we could approach to it.
Conclusion; our results show more increases in the mortality % than American and European studies because we have less facilities and limited resources.
The Victorian Origins of Modern BDSM
Authors: Hines Jade Dawn 
Published: August 2023

<p>People have always flirted with the â€˜darkerâ€™ aspects of desire, those â€˜kinkyâ€™ interests that include sadomasochism, bondage, discipline, and other fetishes, however it was not until the 19th century that these desires became codified. What was unique about Victorian society that caused BDSM to become defined? How did the socioeconomic realities of the industrial revolution impact how such â€˜kinkyâ€™ desires were felt, and how did it change how they were expressed? This MRP aims to explore the multitude of factors which may have affected the formation and development of BDSM subcultures and practices throughout Victorian England. By doing so help explore aspects of sexuality that have often been overlooked by mainstream research.Â </p>

This research investigated Arabic needs for Ugandan -Adults Muallaf (UAM ) using the first phase of ADDIE; Analyze, Design, Develop, Implement, and Evaluate in favor of developing an Elementary Arabic Learning Module (EALM) for UAM. This research marked Step (i) out of ADDIE five steps of academic module development. It was meant to explore Arabic learning needs for UAM in order to identify the major aspects of the proposed EALM development. The study used a descriptive method with a purposive UAM sample size (n=40). The valid and reliable questionnaire of 5 Likert scales was used and the total reliability coefficient of which was ( r )=.984 for 128 items. The major results showed that UAM needed Arabic language for nine major purposes including religious, social, communication, education, business, self-satisfaction, diplomatic, security, and legal purposes. The general implication of the findings confirmed that UAM Arabic weakness was a reflection of weaknesses in their Arabic curriculum. The researchers recommended to consider thise finding in the process of building EALM for UAM with samples of lessons using elementary Arabic grammar, morphology, and Common Arabic Vocabularies (CAV)”.
Common education in schools. Gauging potentials for democratic transformation: a case study from Greece
Authors: Kioupkiolis Alexandros 
Published: August 2023

This article examines how educational commons, in which teaching and learning are shaped by the entire educational community on terms of equal freedom, contribute to democratic empowerment and renewal. Intervening in the critical debate over public formal education and the scope it allows for radical democratization, discussion draws on a case study conducted in the self-organized school Solidarity School Mesopotamia in Moschato, Athens, Greece.The Solidarity School is an informal tutoring or supplementary tuition school which is attached to the formal high school curriculum. One of its main objectives is to support students for the courses they attend in public schools and to prepare them for public school and university entrance exams. This attachment foists constraints on education, however, the commons-based organization and the alter-political nature of the school put a crucial twist on educational practice. This generates considerable transformative effects which are reflected markedly in the ambiance of teaching and learning.The School promotes socio-economic and political equality not only by providing free tuition to students whose families may not be able to afford private supplementary teaching and might not be able thus to enter university or to learn foreign languages. The School nourishes also a culture of equal freedom, solidarity and civic engagement which refashions the hegemonic habitus of consumerist individualism, passivity and submission to socio-political hierarchies.The article argues thus that there is room for educational commons and democratic transformation even in structures which remain tailored to formal schooling but refigure educational hierarchies and modes of governance, infusing education with an alternative democratic ethos of solidarity, equal freedom and grassroots self-organization.

IntroductionDiabetes and thyroid dysfunction often co-exist. One autoimmune disorder always invites another and it has been reported that such co-morbid ailments always become detrimental to the health of the patients.Materials and methodsIn our previous work, we elucidated the interactions of diabetes and hypothyroidism on testicular development and spermatogenesis. However, the present study illuminates the interface between diabetes and hyperthyroidism, where 16 ICR pregnant primiparous mice were used and subsequently 48 male pups were randomly selected (n=12/group) and separated into 4 groups: control (C), diabetic (D), diabetic + hyperthyroidism (DH) and hyperthyroidism (H).ResultsComputerized sperm analyses showed significant reductions in count by 20% and increases of 15% in D and H animals, respectively, vs. controls. However, rapid progressive sperm motility was significantly lower only in D (30%) compared with C mice. Our histomorphometric investigation depicted damaging effects on testicular and epididymal tissues; the stroma adjacent to the seminiferous tubules of the D mice revealed edematous fluid and unstructured material. However, in the epididymis, germ cell diminution contraction of tubules, compacted principal and clear cells, lipid vacuolization, atypical cellular connections, exfoliated epithelial cells, and round spermatids were conspicuous in DH mice.DiscussionCollectively, our experiment was undertaken to ultimately better recognize male reproductive disorders in diabetic-hyperthyroid patients.
The effects of dunite fertilization on growth and elemental composition of barley and wheat differ with dunite grain size and rainfall regimes

Enhanced weathering (EW) of silicate rocks is a negative emission technology that captures CO2 from the atmosphere. Olivine (Mg2SiO4) is a fast weathering silicate mineral that can be used for EW and is abundant in dunite rock. In addition to CO2 sequestration, EW also has co-benefits in an agricultural context. Adding silicate minerals to soils can significantly improve crop health and growth as the weathering releases elements such as silicon (Si) that can stimulate crop growth and increase stress resistance, a co-benefit that is becoming increasingly important as global warming proceeds. However, dunite also contains heavy metals, especially nickel (Ni) and chromium (Cr), potentially limiting its use in an agricultural context. In this study, we investigate the influence of dunite addition on growth of barley and wheat in a mesocosm experiment. We amended the soil with the equivalent of 220 ton ha-1 dunite, using two grain sizes (p80 = 1020 µm and p80 = 43.5 µm), under two rainfall regimes (each receiving the same amount of 800 mm water y−1 but at daily versus weekly rainfall frequency). Our results indicate that the amendment of fine dunite increased leaf biomass but only with daily rainfall. Aboveground biomass was significantly reduced with weekly rainfall compared to daily rainfall, but this reduction was slightly alleviated by fine dunite application for wheat. This indicates a positive effect of dunite during drying-rewetting cycles. For barley the negative effect of reduced rainfall frequency was not counterbalanced by dunite application. Contrary to our expectations, calcium (Ca) and Si concentrations in crops decreased with fine dunite application, while, as expected, magnesium (Mg) concentration increased. Coarse dunite application did not significantly affect crop nutrient concentrations, most likely due to its lower weathering rate. In contrast to what was expected, plant Ni and Cr concentrations did not increase with dunite application. Hence, despite high dunite application in our experiment, plants did not accumulate these heavy metals, and only benefited from the released nutrients, albeit dependent on grain size and rainfall frequency.

Published: August 2023

Background: Vascular-type Ehlers–Danlos syndrome (vEDS) is caused by collagen III deficit resulting from heterogeneous mutations in COL3A1, which occasionally causes sudden death due to arterial/visceral rupture. However, it is difficult to conduct basic research on the pathophysiology of vEDS. Moreover, the number of patients with vEDS is small, limiting the number of available samples. Furthermore, the symptoms of vEDS may vary among family members, even if they share the same mutation. Accordingly, many aspects of the pathology of vEDS remain unknown. Therefore, we investigated the structural abnormalities in collagen fibrils and endoplasmic reticulum (ER) stress in skin samples using electron microscopy as well as their relationship with clinical symptoms in 30 patients with vEDS (vEDS group) and 48 patients without vEDS (disease-negative control group).Methods: Differences between the two groups were evaluated in terms of the sizes of collagen fibrils using coefficient of variation (COV).Results: COV was found to be significantly higher in the vEDS group than in the disease-negative control group, indicating irregularity in the size of collagen fibrils. However, in the vEDS group, some patients had low COV and seldom experienced serious complications and ER stress.Conclusion: ER stress might affect collagen fibril-composing proteins. Moreover, as this stress varies among people based on environmental factors and aging, it may be the underlying cause of varying vEDS symptoms.

BackgroundCervical cancer is the most prevalent gynecologic cancer in women and the second leading cause of cancer death worldwide. Africa's southern, eastern, and western regions have the highest rates of cervical cancer. Cervical cancer is treatable and curable when detected early, but it is nonetheless fatal in low- and middle-income (LMIC) nations where screening and early detection are not widely accessible.ObjectiveThe objective of this study is to assess the magnitude of precancerous cervical lesions and their associated factor among women screened for cervical cancer at a referral center in southern Ethiopia, in 2021.MethodsA retrospective institution-based cross-sectional study was conducted from February 21 to April 14, 2022, among randomly selected 372 records of women screened for cervical cancer at Hawassa University Specialized Hospital. Data were extracted from clients' charts using a data extraction checklist. Statistical Package for Social Sciences version 26 and logistic regression analysis were applied to determine the association between dependent and independent variables, and significance was declared at p-value &lt;0.05.ResultsThe magnitude of abnormal cervical dysplasia in this study was 18.3% of which 14% were precancerous cervical lesions and 4.3% were cervical cancer. Early coitarche: Adjusted odds ratio (AOR) = 5.6 [95% (confidence interval) CI = 1.87–16.78], having more than one sexual partner: AOR = 2.6 [95% CI = 1.2–5.68], being HIV positive: AOR = 3.56 [95% CI = 1.53–8.29], and having sexually transmitted infections: AOR = 4.64 [95% CI = 2.08–10.35] were independent predictors of precancerous cervical lesions.ConclusionThe magnitude of precancerous cervical lesions in the study setting is 18% and the magnitude of cervical cancer is 14%, which is higher than the pooled prevalence of precancerous cervical lesions in Ethiopia. Having multiple sexual partners, being HIV positive, having sexual intercourse before 21 years, and new STI diagnosis was independently associated with abnormal precancerous cervical lesions.
The effectiveness of shockwave therapy on patellar tendinopathy, Achilles tendinopathy, and plantar fasciitis: a systematic review and meta-analysis

Published: August 2023

BackgroundTendinopathy is a growing global concern affecting many people, like athletes, workers, and the elderly. Despite its commonality among the sporting population, there is no practical clinical guideline for patellar tendinopathy (PT). Furthermore, there is conflicting evidence between clinical guidelines on shockwave therapy’s application and clinical utility for Achilles tendinopathy (AT) and plantar fasciitis (PF). Thus, our aim of this study is to evaluate the evidence for shockwave therapy; to provide a Grading of Recommendation, Assessment, Development and Evaluation (GRADE) level of the evidence and effectiveness of shockwave therapy for patellar tendinopathy, Achilles tendinopathy, and Plantar fasciitis.MethodMedical Literature Analysis and Retrieval System Online (Medline), Embase, The Cumulative Index to Nursing and Allied Health Literature (CINAHL), Physiotherapy Evidence Database (PEDro) and China National Knowledge Infrastructure database (CNKI) were searched to find relevant studies published before December 14th, 2022.ResultsOur study showed that for PT in the short term, extracorporeal shockwave therapy (ESWT) or ESWT + eccentric exercise (EE) has a negligible effect on pain and function compared to a placebo or placebo + EE. On the contrary, ESWT significantly affects pain compared to conservative treatment (CT). For AT, ESWT has a small inconclusive effect on pain and function in the short term compared to EE. On the other hand, a placebo outperformed ESWT in improving function for AT but not pain outcomes. PF showed that ESWT significantly affects short- and long-term pain and function. When ESWT was compared to other interventions such as low laser therapy (LLLT), corticosteroid injection (CSI), or CT, there was a small inconclusive effect on pain and function in the short term.ConclusionThere is low-moderate evidence that ESWT has a negligible effect on pain and function for PT and AT. However, high-quality evidence suggests ESWT has a large effect on pain and function for PF.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42023396835, identifier CRD42023396835.

BackgroundPre-existing cross-reactive immunity among different coronaviruses, also termed immune imprinting, may have a comprehensive impact on subsequent SARS-CoV-2 infection and COVID-19 vaccination effectiveness. Here, we aim to explore the interplay between pre-existing seasonal coronaviruses (sCoVs) antibodies and the humoral immunity induced by COVID-19 vaccination.MethodsWe first collected serum samples from healthy donors prior to COVID-19 pandemic and individuals who had received COVID-19 vaccination post-pandemic in China, and the levels of IgG antibodies against sCoVs and SARS-CoV-2 were detected by ELISA. Wilcoxon rank sum test and chi-square test were used to compare the difference in magnitude and seropositivity rate between two groups. Then, we recruited a longitudinal cohort to collect serum samples before and after COVID-19 vaccination. The levels of IgG antibodies against SARS-CoV-2 S, S1, S2 and N antigen were monitored. Association between pre-existing sCoVs antibody and COVID-19 vaccination-induced antibodies were analyzed by Spearman rank correlation.Results96.0% samples (339/353) showed the presence of IgG antibodies against at least one subtype of sCoVs. 229E and OC43 exhibited the highest seroprevalence rates at 78.5% and 72.0%, respectively, followed by NL63 (60.9%) and HKU1 (52.4%). The levels of IgG antibodies against two β coronaviruses (OC43 and HKU1) were significantly higher in these donors who had inoculated with COVID-19 vaccines compared to pre-pandemic healthy donors. However, we found that COVID-19 vaccine-induced antibody levels were not significant different between two groups with high levelor low level of pre-existing sCoVs antibody among the longitudinal cohort.ConclusionWe found a high prevalence of antibodies against sCoVs in Chinese population. The immune imprinting by sCoVs could be reactivated by COVID-19 vaccination, but it did not appear to be a major factor affecting the immunogenicity of COVID-19 vaccine. These findings will provide insights into understanding the impact of immune imprinting on subsequent multiple shots of COVID-19 vaccines.
