Abstract Objective. To compare the bleeding patterns associated with the
3-year use of copper intrauterine devices (Cu-IUD) or 13.5-mg
levonorgestrel-releasing intrauterine systems (LNG-IUS) in clinical
practice. Design. Single-centre, double-blind, randomized, parallel
group, Phase IV study. Setting. Gynaecology office. Population or
Sample. Women seeking long-term contraception, eligible to use
Cu-IUD/LNG-IUS. Methods. At baseline and at months 3, 6, 12, 24 and 36
after placement, we recorded the number of bleeding days and quantity of
bleeding: self-reported bleeding intensity, the Pictorial Blood
Assessment Chart (PBAC) and haemoglobin/ferritin levels and haematocrit.
The frequency and intensity of dysmenorrhoea and spotting, and of
adverse events were also recorded. Main Outcome Measures. Bleeding days
and quantity of bleeding in 90-day reference periods (RPs). Results.
One-hundred six women aged 32.5±6.7 years participated in the study: 55
women were randomized to LNG-IUS and 51 to Cu-IUD. The median number of
bleeding days and the bleeding intensity (self-perceived and PBAC score)
were significantly lower with LNG-IUS throughout the study (P
<0.001), with a greater reduction during RP2 (month 2 for
PBAC). Ferritin levels increased with LNG-IUS and decreased with Cu-IUD.
The frequency and intensity of dysmenorrhoea decreased significantly
more with LNG-IUS vs Cu-IUD. The median number of spotting days was 0 or
close to 0 throughout the study with both devices. Conclusions The
13.5-mg LNG-IUS shows benefits over the Cu-IUD in terms of menstrual
bleeding pattern, being associated with significant blood loss reduction
and greater reduction of the frequency and intensity of dysmenorrhoea,
with similar patterns of spotting days.
Improving the performance of fermionic neural networks with the Slater exponential Ansatz
Authors: Bokhan Denis , Kolchenko Maria , Boev Aleksey , Fedorov Aleksey , Trubnikov Dmitrii
Published: October 2022

In this work, we propose a technique for the use of fermionic neural
networks (FermiNets) with the Slater exponential Ansatz for
electron-nuclear and electron-electron distances, which provides faster
convergence of target ground-state energies due to a better description
of the interparticle interaction in the vicinities of the coalescence
points. Our analysis of learning curves indicates on the possibility to
obtain accurate energies with smaller batch sizes using arguments of the
bagging approach. In order to obtain even more accurate results for the
ground-state energies, we propose an extrapolation scheme for estimating
Monte Carlo integrals in the limit of an infinite number of points.
Numerical tests for a set of molecules demonstrate a good agreement with
the results of the original FermiNets approach (achieved with larger
batch sizes than required by our approach) and with results of the
coupled-cluster singles and doubles with perturbative triples (CCSD(T))
method that are calculated in the complete basis set (CBS) limit.

Published: October 2022

In this work, we studied the correlation properties of seismic networks by analyzing the assortativity of worldwide and synthetic earthquake networks. We used data from the World Earthquake Catalog for the period from 2002 to 2016, considering earthquakes with magnitude thresholds 4.5 and 5.0. Shallow earthquakes (a depth of up to 70 km) and deep earthquakes (a depth greater than 70 km) were analyzed separately. Synthetic data were produced from simulations using a modified version of the Olami-Feder-Christensen model, which can reproduce several statistical characteristics of actual earthquakes. The study was carried out for two methodologies of connections between the network elements, where the correlation measures were calculated for all networks. The results for shallow earthquakes and synthetic data indicate: assortative correlation (locations with similar seismic activities tend to have a greater number of connections between them); mainshocks induce other mainshocks in both close and further away regions; the structure found has a type of “attracting dynamics”, where the places with a more intense seismic activity produce large numbers of connections in other locations around them. Deep earthquake networks are neutral and therefore do not have an explicit correlation type. Our findings agree with previous works for specific areas and contribute to better understand correlations between seismological regions.
Signal Decomposition and Time-Frequency Representation Using Variable-Length Symmetric Filters
Authors: Porsani Milton José , Ursin Bjorn
Published: October 2022

We present a time-frequency decomposition method to represent a time signal into a 2D (time X frequency) image, which describes how the frequency content varies along the time. This is done in two steps: firstly, by filtering the signal to obtain time-components; and secondly, by computing the average instantaneous frequency (AIF), which is used for moving the data components to the time-frequency plane. For the filtering process, we present an algorithm to generate a suite of symmetric filters that are computed recursively, starting with the high-frequency content of the signal, going down in frequency and leaving the lowest frequencies in the last filter component. This can be further decomposed by continuing the procedure. The symmetric impulse responses are zero-phase with positive frequency response, and they add up to a spike at the origin with a unit frequency response. The filtering procedure gives an exact decomposition of the signal and the traveltimes are preserved. Next, the analytic signal of each component is used for computing the AIF in sliding time windows, so that for each time sample, we have an associated AIF value. The 2D time-frequency plane is obtained by distributing and adding the data components along the frequency variable. Finally, by using the time X frequency distribution, a time-frequency filtering may be performed by stacking data of sub-domains with similar features. The new technique has been applied to two synthetic signals which have previously been analyzed by many authors using a variety of algorithms. The new signal decomposition algorithm and the AIF computation are simple and produce effective results on the synthetic data.

Authors: Arellano Solis Sonia , Rojas Sánchez Isaura , Larios Sánchez José Mauro
Published: October 2022

Problemática: la denominación de Pueblo Mágico, otorgada en el año 2011 a Xicotepec de Juárez, no evidencia que existan mejoras sustantivas tanto para sus pobladores como para los empresarios del sector turístico. Objetivos: determinar estrategias de desarrollo económico y sostenible en Xicotepec, Pueblo Mágico. Materiales y métodos: investigación de carácter cuantitativo con diseño no experimental, transeccional y descriptivo. Se aplicaron dos cuestionarios tipo encuesta a 76 empresarios y 355 ciudadanos en el municipio de Xicotepec. Resultados: principalmente, se encuentra que los ciudadanos no perciben la denominación de Pueblo Mágico como un factor detonante del turismo y tampoco como elemento que mejore su calidad de vida, debido a que el 49,86 % de los pobladores considera que es regular y el 21,69 % malo. Por otra parte, los empresarios reflejan varias áreas de oportunidad en el ámbito laboral y de operación. Sin embargo, la evaluación que le dan a la denominación de Pueblo Mágico es regular para el 65,79 % y solo el 23,68 % considera que es algo bueno. Discusión: en términos generales, se percibe que Xicotepec, al igual que otros Pueblos Mágicos, cuenta con diversas problemáticas para que el turismo sea considerado como un verdadero detonante de desarrollo local y sea un factor de beneficio tanto para pobladores como para empresarios. Conclusiones: Xicotepec tiene la oportunidad de generar nuevas formas de vivir en su entorno social, económico, competitivo y sustentable. Se requieren redes y vínculos de colaboración que permitan contribuir a una comercialización de apertura y fortalecimiento turístico, que impacte significativamente a las familias xicotepenses. Contribución / originalidad: la principal contribución de este trabajo tiene que ver con la identificación de los aspectos actuales que viven tanto pobladores como empresarios, los cuales pueden servir de base para que los actores decisores implementen estrategias de mejora.

Published: October 2022

This study aimed to investigate the endophytes of Juniperus macrocarpa
collected from ?esme in ?zmir, Turkey, using a culture-dependent approach
and to evaluate their antimicrobial activity for the first time. Since
endophytes interact with phytochemicals of the host plant, in addition to
the standard culture media, a J. macrocarpa extract supplemented culture
media was also used for isolation to enhance the cultivability of the
endophytes. Six bacteria out of twelve and three fungi out of seven were
isolated from the plant extract supplemented culture media. The genotypic
identification of the bacterial and fungal isolates was determined based on
16S rDNA and Internal Transcribed Spacer (ITS) sequence analysis,
respectively. The genus Juniperus, which has ethnopharmacological uses, is
rich in phytochemicals with multiple bioactivities. Since Juniperus spp. is
listed as a priority natural habitat, it is necessary to find alternative
resources that could replace the bioactive compounds of these plants.
Endophytes of Juniperus spp. might be good candidates as antimicrobial
producers. From this point of view, the antimicrobial activity of the crude
fermentation liquid of the J. macrocarpa endophytes, and also aqueous and
methanolic extracts of J. macrocarpa, were evaluated using a disc diffusion
assay against a panel of test microorganisms, including antibiotic resistant
ones. One fungus and seven bacteria showed remarkable antimicrobial activity
against at least one test microorganism. These results indicated that some
endophytes of J. macrocarpa had antimicrobial properties like their host
plant and could substitute these plants as a source of antimicrobials.

Published: October 2022

The present study was designed to evaluate the biological potentials and
phenolic composition of different parts of Glaucosciadium cordifolium, which
is less investigated and known as a wild endemic species to Turkey. The
antioxidant activity of the plant was determined using
2,2-diphenyl-1-picrylhydrazyl (DPPH),
2,2'-Azinobis-(3-Ethylbenzthiazolin-6-Sulfonic Acid) (ABTS), iron chelating
capacity, and a ?-carotene / linoleic acid emulsion assay. The total phenol
and flavonoid contents of the plant were determined using the
Folin-Ciocalteu and aluminum chloride methods, respectively. The study of
the enzyme inhibition activity of the plant was carried out for
acetylcholinesterase, butyrylcholinesterase, ?-glucosidase, ?-amylase, and
tyrosinase. The antiglycation activity of the aqueous extract of the plant
was evaluated using established methods such as browning, a
Nitroblue-tetrazolium (NBT) assay, the 2,4-dinitrophenyl hydrazine (DNPH)
method, a Congo red assay, and fluorescent Bovine Serum Albumin (BSA). The
HPLC profiling of the phenolics revealed that 18 standard phenolic compounds
were found in different amounts in various extracts of the plant parts.
According to our bioactivity results, the methanol extract obtained from the
flower parts of the plant contained higher amounts of phenolic compounds and
flavonoids, which also demonstrated the highest DPPH radical scavenging
activity. In addition, the methanol extracts obtained from the leaves and
roots were found to be the most active extracts against the
acetylcholinesterase enzyme, as well as moderately active against the
tyrosinase enzyme. The antiglycation capacity of the extract followed this
order: G. cordifolium leaves > stems > roots > flower. As a result, our
study indicated that G. cordifolium extracts have strong antioxidant
potential, good enzyme inhibitory effects and antiglycation potential.
Further studies on G. cordifolium with in vivo bioassays need to be carried
out to seek the importance of the plant in pharmaceutical techniques.

The Dual-Role Framework: A Structured Approach for Analyzing Management Controls
Authors: Bol Jasmijn C. , Loftus Serena
Published: October 2022

We provide a conceptual framework for analyzing studies on management controls and management control systems (MCSs). This framework describes and analyzes the directing and activating processes of management controls and MCSs. Because our focus is on why management controls are effective, our conceptual framework complements earlier frameworks that focus on specific empirical methods, controls, and literature maps. We discuss several applications of the framework, such as depicting an individual research study, comparing multiple research studies examining the same control, and organizing an area of research. Our approach benefits consumers of management accounting research by increasing understanding and access to extant research. In addition, the application of our approach can reveal gaps in the literature or the potential for mediating factors to explain conflicting findings and can thus inform future research.
Banking Market Consolidation and Tax Planning Intermediation: Evidence from Client Firm Tax Haven Operations
Authors: Kim Jeong-Bon , Lin Yupeng , Mao Ying , Wang Zheng
Published: October 2022

This study examines the effect of banking market consolidations via mergers and acquisitions (M&As) on the role of banks in intermediating corporate tax planning through offshore tax haven operations. We find that bank clients significantly increase their tax haven operations after their banks are merged with others. In addition, such an increase is greater when a commercial bank merges with an investment bank and when the clients have greater tax planning opportunities. We also employ network analyses to show that the propensity for a client to expand its operations into a new tax haven country increases significantly when its relationship bank enters into this country through an M&A. Collectively, our findings reveal that bank M&As enhance banks’ tax intermediation capability.

OBJECTIVE

To estimate diabetes-related mortality in Mexico in 2020 compared with 2017–2019 after the onset of the coronavirus disease 2019 (COVID-19) pandemic.

RESEARCH DESIGN AND METHODS

This retrospective, state-level study used national death registries of Mexican adults aged ≥20 years for the 2017–2020 period. Diabetes-related death was defined using ICD-10 codes listing diabetes as the primary cause of death, excluding certificates with COVID-19 as the primary cause of death. Spatial and negative binomial regression models were used to characterize the geographic distribution and sociodemographic and epidemiologic correlates of diabetes-related excess mortality, estimated as increases in diabetes-related mortality in 2020 compared with average 2017–2019 rates.

RESULTS

We identified 148,437 diabetes-related deaths in 2020 (177 per 100,000 inhabitants) vs. an average of 101,496 deaths in 2017–2019 (125 per 100,000 inhabitants). In-hospital diabetes-related deaths decreased by 17.8% in 2020 versus 2017–2019, whereas out-of-hospital deaths increased by 89.4%. Most deaths were attributable to type 2 diabetes (130 per 100,000 inhabitants). Compared with 2018–2019 data, hyperglycemic hyperosmolar state and diabetic ketoacidosis were the two contributing causes with the highest increase in mortality (128% and 116% increase, respectively). Diabetes-related excess mortality clustered in southern Mexico and was highest in states with higher social lag, rates of COVID-19 hospitalization, and prevalence of HbA1c ≥7.5%.

CONCLUSIONS

Diabetes-related deaths increased among Mexican adults by 41.6% in 2020 after the onset of the COVID-19 pandemic, occurred disproportionately outside the hospital, and were largely attributable to type 2 diabetes and hyperglycemic emergencies. Disruptions in diabetes care and strained hospital capacity may have contributed to diabetes-related excess mortality in Mexico during 2020.

Published: October 2022

  

Tayside is a region in the East of Scotland and forms one of nine local government regions in the country. It is home to approximately 416,000 individuals who fall under the National Health Service Tayside (NHS Tayside) health board who provide healthcare services to the population. In Tayside, Scotland a comprehensive informatics network for diabetes care and research has been established for over 25 years, expanding more recently to a comprehensive Scotland-wide clinical care system, Scottish Care Information-Diabetesor SCI-Diabetes. This has enabled improved diabetes screening, integrated management of diabetic retinopathy, neuropathy, nephropathy, cardiovascular health, and other comorbidities. The regional health informatics network links all these specialized services with comprehensive laboratory testing, prescribing records, general practitioner records, and hospitalization records. Not only do patients benefit from the seamless interconnectedness of these data, the Tayside bioresource has enabled considerable research opportunities and the creation of biobanks. This review describes how health informatics has been used to improve care of people diabetes in Tayside and Scotland and, through anonymized data linkage, our understanding of the phenotypic and genotypic etiology of diabetes and associated complications and co-morbidities.

Transcriptional and functional cellular specialization has been described for insulin-secreting β-cells of the endocrine pancreas. However, it is not clear whether β-cell heterogeneity is stable or reflects dynamic cellular states. We investigated the temporal kinetics of endogenous insulin gene activity using live cell imaging, with complementary experiments employing FACS and single cell RNA sequencing, in β-cells from Ins2GFP knock-in mice. In vivo staining and FACS analysis of islets from Ins2GFP mice confirmed that at a given moment, ~25% of β-cells exhibited significantly higher activity at the evolutionarily conserved insulin gene Ins2. Live cell imaging over days captured Ins2 gene activity dynamics in single β-cells. Autocorrelation analysis revealed a subset of oscillating cells, with mean oscillation periods of 17 hours. Increased glucose concentrations stimulated more cells to oscillate and resulted in higher average Ins2 gene activity per cell. Single cell RNA sequencing showed that Ins2(GFP)HIGH β-cells were enriched for markers of β-cell maturity. Ins2(GFP)HIGH β-cells were also significantly less viable at all glucose concentrations and in the context of ER stress. Collectively, our results demonstrate that the heterogeneity of insulin production, observed in mouse and human β-cells, can be accounted for by dynamic states of insulin gene activity. 
Når målrørsla normerer seg sjølv: normeringsprinsipp, husnormer og skrivereglar
Authors: Hope Fredrik
Published: October 2022

Artikkelen granskar i kva grad nynorskorganisasjonar brukar eigne husnormer til å påverka framtidig offentleg normering av nynorsk, kva normeringsprinsipp dei legg til grunn for eigen språkbruk, og korleis dei stiller seg til den offisielle nynorsknorma. Materialet er svara på ei kvalitativ spørjeundersøking til medlemsorganisasjonane i Nynorsk forum og normdokumenta deira. Funna er at mindretalet svarar at dei har husnormer, og fleire som meiner at dei ikkje har husnormer, har andre typar reguleringar av språkbruken sin, anten knytt til situasjon, teksttypar eller mottakarar. Normeringsprinsippa valfridom og demokrati har stor støtte. I nynorskorganisasjonar både med og utan husnormer står tilsette og tillitsvalde fritt innanfor nynorsknorma i mange situasjonar. Fleirtalet av dei som leverer tekst til korpus, har husnormer, men grunngjevinga er heller praktiske omsyn enn eit ynske om å endra nynorskrettskrivinga. Med nokre få unntak held alle normene seg innanfor den offisielle nynorsknorma, og materialet syner ei brei støtte til at nynorsknormeringa skal styrast av demokratisk valde organ.
Nok tilfang på begge målformer? Om språkleg fordeling i lesebøker og tekstar i norsk for nynorskelevar i ungdomsskulen
Authors: Skåre Langnes Liv Astrid
Published: October 2022

Spørsmålet om nynorskelevane vert nok eksponerte for hovudmålet sitt til å meistre det godt, har vorte stilt av fleire. Denne studien undersøker spørsmålet ved å presentere ei gransking av språkleg fordeling mellom tekstar på nynorsk og bokmål i nynorske lesebøker for to norskverk i ungdomsskulen, Fabel 8–10 og Kontekst 8–10. For å undersøke kva målform tekstane elevane les i norskfaget har, er også faglærarrapportar frå skular med nynorsk som hovudmål som brukar dei aktuelle bøkene med i granskinga. Faglærarrapportar er dokument i skulen som minner om tidlegare pensumlister. Studien presenterer også bakgrunnen for dei to læreverkforlaga sin praksis for utval av tekstar til lesebøkene som resultat frå kvalitative intervju med forlagsrepresentantar. Dei undersøkte lesebøkene har om lag 1/3 tekstar på nynorsk jamført med 2/3 på bokmål, og den språklege fordelinga mellom tekstane som er lista opp i faglærarrapportane, er tilsvarande. Forlaga meiner det er læreplanen og ikkje lesebøkene som skal vere styrande for kva elevane skal lese for å nå kompetansemåla. Implikasjonar av den språklege fordelinga for nynorskelevane si meistring av den nynorske språknorma blir drøfta i lys av teoriar om samanhengar mellom leseeksponering og literacy.
Tekstar på nynorsk i klasserom der bokmål er hovudmål – ei undersøking av lærarar sin bruk av og haldning til tekstar på nynorsk
Authors: Nordeide Britt Iren
Published: October 2022

Forsking på kva tekstar ein les i skulen i Noreg har helst handla om lesing av skjønnlitteratur og sakprosa, og mindre om kva målform tekstane som vert lesne i klasseromma, har. Fleirtalet av norske born møter nynorsk for første gong i skulen, og skulen har såleis eit viktig formidlingsoppdrag. Dette skjer i klasserommet, og undervisinga som vert gitt, er avhengig av læraren sin kunnskap og haldningar, kva læremiddel som er tilgjengelege, og korleis desse læremidla vert nytta. I artikkelen kjem det fram at lærarane som var med i denne studien, stort sett er positive til å lese tekstar på nynorsk. Tekstane som desse lærarane brukar, er i stor grad skjønnlitterære tekstar, henta frå læreverk i norskfaget og knytte opp til estetiske arbeidsmåtar der elevane sine opplevingar av tekst spelar ei sentral rolle. Lærarane brukar læreverka i stor grad, men er kritiske til det dei meiner er eit snevert tekstutval, spesielt når det gjeld sakprosatekstar på nynorsk.
Podkast som undervisingsform: språkhistorisk aktørskap i møte med nynorsk
Authors: Lunde Kirsti , Thingnes Jorunn Simonsen
Published: October 2022

Språkhistorieundervising er sentral for å gjere studentar medvitne om toskriftspråkssituasjonen i Noreg, det historiske opphavet til han, og kva som kjenneteiknar han i dag. Denne artikkelen syner korleis ein kan nytte podkast som undervisingsform for å formidle nynorsk gjennom norsk språkhistorie på ein måte som let elevar og studentar bli aktørar i den historiske og samtidige språksituasjonen. Datamaterialet er sju podkastepisodar produserte av grunnskulelærarstudentar ved Høgskulen på Vestlandet. Me spør korleis studentane trekkjer på eigne røynsler som språkbrukarar i formidling av norsk språkhistorie. Analysen syner at studentane tek ei aktørrolle og får eit styrkt medvit om samanhengen mellom historiske hendingar og den norske språkstoda i dag. Me argumenterer for at dette medvitet er viktig i formidlinga av nynorsk fordi det gjev studentane forståing for den norske språksosiologiske stoda. Med utgangspunkt i empirien og didaktisk forsking føreslår me avsluttingsvis korleis læraren kan knyte band til språksosiologiske tema i ein heilklassesamtale.
Heritagisation and Community Formation in the Pivško Region
Authors: Habinc Mateja
Published: October 2022

Pivško is a small region in south-western Slovenia that appropriated a nationally recognised literary hero named Martin Krpan as its most visible heritage. The article questions if this act of appropriation correlates with what the inhabitants of the Pivško region consider as examples their personal, family, local or regional heritage. These various heritages are observed through the prisms of (political) power relations and community-building processes, while the main question addressed in the article is, the symptom of what any of those heritages are. The power and uses of heritages are therefore considered as well as their capacity to overcome already existing macro-social definitions, hierarchies and positions. The research sample of mostly middle-aged or older generations, local activists or representatives of various associations or political bodies revealed that the heritage of the Pivško region is diverse, related to the natural environment and personal life histories, while Martin Krpan was rarely considered a part of it. Despite its variety of interpretations, the common denominator for heritage is its capacity to serve as a mechanism of social cohesion and community formation. However, while mostly viewed as a remedy against individualisation and alienation, heritage at the same time reproduces existing socio-political power relations and, especially when compared to the creative industries, is only rarely considered an additional or exclusive existential opportunity.

Published: October 2022

Penelitian ini bertujuan untuk menjelaskan keberadaan isu politik identitas dalam kaitannya dengan perilaku memilih masyarakat dan isu primordial sebagai politik identitas terhadap perilaku memilih pada pemilihan Gubernur dan Wakilnya pada Provinsi Sumatera Utara tahun 2018 di Desa Sei Bamban. Metode penelitian yang digunakan adalah penelitian kualitatif dengan pendekatan deskriptif. Data dikumpulkan melalui wawancara, studi literatur dan dokumentasi. Hasil penelitian yaitu: adanya kaitan keberadaan isu politik identitas ditengah masyarakat terhadap perilaku memilih sebagian besar masyarakat. Isu yang paling menonjol di masyarakat adalah tentang teritorial yaitu putra daerah dan bukan putra daerah. Kemudian isu primordial yang dilakukan sebagian besar masyarakat didalam menentukan pilihan politiknya terlihat dari segi agama, suku, bahkan hubungan ikatan keluarga atau kekeluargaan. Artinya pemilih yang menentukan pilihannya berdasarkan teritorial, ikatan keluarga dan agama adalah pemilih mayoritas Muslim dengan pasangan nomor urut 1. Sedangkan pemilih yang menentukan pilihan berdasarkan suku, ikatan kekeluargaan, dan agama adalah pemilih mayoritas Non-Muslim dengan pasangan urut 2.  This study aims to explain the existence of the issue of identity politics in relation to people's voting behavior and primordial issues as identity politics on voting behavior in the election of the Governor and Deputy in North Sumatra Province in 2018 in Sei Bamban Village.The research method used is qualitative research with a descriptive approach. Data were collected through interviews, literature study and documentation.The results of the study are: there is a relationship between the existence of the issue of identity politics in the community towards the voting behavior of most people.The most prominent issue in the community is about territory, namely the sons of the region and not the sons of the region.Then the primordial issues that are carried out by most people in determining their political choices can be seen in terms of religion, ethnicity, and even family or kinship ties.This means that the voters who make their choice based on territoriality, family ties and religion are the majority Muslim voters with a pair number 1.While the voters who make choices based on ethnicity, kinship, and religion are the majority voters of Non-Muslims with pair 2.

Published: October 2022

Remedial learning is given to students through two main stages: the diagnosis of learning difficulties and remedial treatment. All remedial learning must end with a retest. The main stage of remedial learning is often overlooked in the implementation of remedial learning in schools. This study aims to determine the understanding, implementation, and problems of remedial learning in biology subjects in odd semester students of Class XI MIPA SMA. This research is descriptive qualitative research using data analysis techniques Miles and Huberman's model. The instruments used were questionnaires and interviews. The results showed that the teacher's understanding of remedial learning could be categorized as good. The implementation of remedial is in the very good category, except for the time for implementing remedial learning, which is in the category of less suitable remedial technical guidelines. The category of remedial learning problems in biology subjects is insufficient. However, the interview results showed a lack of time planning by schools related to remedial implementation at the end of each basic competency. Remedial learning in biology subjects in class XI SMA needs to pay attention to the time aspect in the implementation and planning of learning by schools and teachers.

Misconceptions result in poor student learning outcomes and become an obstacle in the other learning process. It is necessary to know exactly where the students' misconceptions lie. This type of research is a meta-analysis by collecting, analyzing, and summarizing the results of relevant research in the form of articles that have been previously researched. Of the six research results regarding misconceptions in Biology students of class XII IPA analyzed, it is inseparable from students' misconceptions that are quite varied. The catabolism sub material that experienced the largest and smallest student misconceptions, respectively, was the indicator identifying each step that occurred in cellular respiration and the indicator determining the ratio of fermentation and aerobic respiration. Catabolism contained quite complicated stages with complex terms. To be remembered and understood by students who can trigger misconceptions. The higher the percentage of students' misconceptions, the lower students' understanding of the concepts in the material. Overall, students' misconceptions are caused by internal factors (students themselves) and external factors such as teachers, textbooks, and the context of the material being studied. Further action is needed on the part of teachers and related organizations to ensure efforts are made to reduce misconceptions among students.

Published: October 2022

Science education aims to enable teachers to teach problem-solving in the teaching and learning process. Students should have at least two competencies to achieve learning objectives, including metacognitive abilities and the ability to recognize their potential, interests, talents. The ability to recognize potential, interests, and talents are related to self-concept. One alternative learning model that can develop a positive self-concept and train students' metacognitive abilities is the problem-based learning model. The learning process on the excretory system material demands a process of discovery and problem solving that trains students' metacognitive abilities. This study aims to determine the effect of the Problem Based Learning model on students' self-concept and metacognitive abilities. The research sample was two classes obtained based on the purposive sampling technique. The research design used is the Pretest-Postest Nonequivalent Control Group Design. The research data was obtained from self-concept questionnaires and students' metacognitive abilities. The results showed that the average value of self-concept and metacognitive abilities of students taught using the PBL model was more significant than the class taught using the DL model. The results of hypothesis testing and effect size also show that the PBL model significantly affects students' self-concept and metacognitive abilities with scores of 1.9 (high) and 2.4 (high).
