NIGERIA: FACE ACTS IN ALTERNATIVE DISPUTE RESOLUTION TELEVISION PROGRAM. THE CASE OF IGBIMO IPETU
Authors: AJAYI Temitope Michael , AJAYI Oluwatosin , FASHINA Rahidat Temitope
Published: July 2021

The concept of alternative dispute resolution (ADR) has largely been under explored from the linguistic lens, particularly in the Nigerian context. This study thus provides a scholarly intervention in this regard. Drawing insights from Brown and Levinson’s face theory, four randomly sampled recordings of Ìgbìmo Ìpètù, an alternative dispute resolution television programme on the Ekiti State Television (EKTV) in southwestern Nigeria was analysed in this study. Focus was placed on the face acts as well as their pragmatic functions in the programme. Findings revealed that bald on-record face-threatening acts (FTA), bald off-record FTA and positive face acts characterized the discursive interaction of participants on the programme. While bald onrecord and off-record FTAs were deployed by the panel to criticize and condemn actions considered unsavory on the part of complainants and the accused, complainants and accused persons deployed on-record FTAs to protest/redress the panel’s decisions found unacceptable. The panel used positive face acts as a general principle in the interaction, particularly with cooperative accused persons, while accused persons deployed positive face acts to negotiate the discursive interaction and for face-damage repair. Keywords: Alternative dispute resolution, dispute and media, face acts.
The springs from the ”Făget” area of Cluj.
Authors: VIGH MELINDA , POSZET SZ. , WANEK F.
Published: July 2021

To the south of the city of Cluj, in the perimeter called “Făget”, there are numerous springs often frequented by locals. From a geological point of view, there is a great variety of rocks of different ages and characteristics. The waters cantoned in these geological structures appear on the surface along the valleys, on the slopes or even in the unevenness of the interfluves. Their existence was facilitated by vertical erosion processes and mass movements of the material. Through the inventory of the area, 28 sources were identified and located. They can be divided into several categories: with drain, wells, inactive, dried, captured. Spatial coordinates were determined for each source. Where possible, the flow rate, temperature and concentration of dissolved in water substances were measured. There is a large gap in flow variation, relatively constant temperatures and wide limits of TDS values. The expansion of the urban area involves potential risks of a quantitative and qualitative nature.

Published: July 2021

The study presents geologic investigation of Yemen and the Gulf of Aden with a special focus on geophysical, seismic, tectonic and topographic mapping performed by the integrated approach of QGIS and GMT scripting. Cartographic visualization is crucial in geologic analysis, data processing and prognosis of mineral resource prospects. The region of Yemen and Gulf of Aden was formed as a result of Arabian and African plates movements and still tectonically active. Besides, the Gulf of Aden contains mineral resources of hydrocarbons which makes this region actual for investigation. The IRIS database on earthquakes was used for visualization of the magnitude of submarine earthquakes in the Gulf of Aden for the period of 2007-2020. The paper presents 6 new thematic maps for the region of Yemen and Gulf of Aden. The research presented an analysis of correlation between the geological, topographic and geophysical settings. Through combined approach of cartographic high-resolution data visualization and geologic analysis, this paper contributed to the regional geological studies of Yemen, Gulf of Aden and the Middle East.
Episode with strong downslope wind in the Southern and Curvature Carpathians in the period 5-6 february 2020
Authors: HUȘTIU M.H. , BOARIU A.
Published: July 2021

The phenomenon that occurred during the blizzard from February 5-6 in the mountains and especially on the southern slopes of the Southern Carpathians, is known in the literature as "strong downslope winds". This phenomenon occurred in a typical blizzard configuration, in which the differentiated advection of temperature led to the formation of a very stable air layer, with thermal inversion approximately between the levels of 850 and 700 hPa; and it also contributed in this layer to the change of wind direction to vertical. Thus, the existence in the same air layer of two factors favorable to the formation of a critical level, created the ideal conditions for generating strong downslope winds.

Ocena przydatności tomografu dźwiękowego w diagnozowaniu zdrowotności drzew zasiedlonych przez szkodniki owadzie
Authors: Durlak Wojciech , Górska-Drabik Edyta
Published: July 2021

W badaniach określono przydatność tomografii dźwiękowej do oceny stanu zdrowotnego sosny pospolitej i olszy czarnej zasiedlonych przez szkodniki owadzie. Phaenops cyanea, Rhagium inquisitor, Arhopalus rusticus żerujące na sośnie oraz monofagiczny gatunek Synanthedon mesiaeformis występujący na olszy to szkodniki wtórne, które zasiedlają drzewa osłabione przez różne czynniki środowiskowe. Do badań wybrano dwie sosny pospolite i dwie olsze czarne rosnące na terenie leśnictwa Macoszyn w kompleksie lasu świeżego. Zastosowano urządzenie Picus 3 bazujące na metodzie tomografii akustycznej. Wykorzystuje ona właściwości fali dźwiękowej, generowanej po obwodzie pnia, dostarczając informacji o stanie zdrowotnym drewna. Oceniane sosny zasiedlone przez szkodniki wtórne były już martwe, jednak otrzymane wyniki z tomografu sugerowały 100% sprawność techniczną drewna, nie wykazując przy tym uszkodzeń spowodowanych przez owady. U olszy czarnej analiza tomograficzna wykazała znaczne uszkodzenia wewnętrznych struktur drewna (25 i 49%), ale nie były one spowodowane żerowaniem szkodnika a raczej rozkładem próchniczym. Tomografia dźwiękowa nie odzwierciedla rzeczywistego obrazu uszkodzeń spowodowanych przez owady, ale może być narzędziem do typowania drzew osłabionych, które mogą być atakowane przez szkodniki wtórnie.

The history of participatory budget (PB) in Poland is less than 10 years old. The occurrence of PB was to raisethe local government to a higher level of civil society by introducing so-called deliberative democracy. Forsome contemporary political thinkers, what defines politics is intersubjective dialogue conducted by citizensin an open and public space. Deliberative democracy is characterized by: a) elementary competences of theparticipants who have to become acquainted with the material concerning the issue concerned b) the needto formulate their position, which is the result of reflection, reflection on the issue c) civic debate where allproposals have the right to be presented, argued and discussed. The subject of this paper is the civic budget,also referred to as participatory budget (both names are often used interchangeably) as an expression of thewillingness of citizens to allocate funds that are available to local authorities. Editions of the citizens’ budgetin Krakow between 2014 and 2019 were analysed, the procedure and functions of this social institution wereshown.

PENGARUH BENTUK GEOMETRI PEMASANGAN LAMPU LED TERHADAP AKURASI INDOOR PSITIONING LI-FI MENGGUNAKAN TEKNIK RECEIVE SIGNAL STRENGTH (RSS)
Authors: Prayuda Jaka Satria , Darlis Denny , Hambali Akhmad
Published: July 2021

Informasi untuk mengetahui lokasi benda atau seseorang merupakan salah satu hal yang penting dalam kehidupan sehari-hari. Selama ini, teknologi Global Positioning System (GPS) dapat diandalkan ketika berada di luar ruangan. Namun, ketika di dalam ruangan, GPS akan sulit menjangkau secara spesifik area bangunan. Dengan memanfaatkan teknologi Light Fidelity (Li-Fi), Indoor Positioning System (IPS) akan lebih mudah dilakukan dan mempunyai keunggulan dari segi akurasi dan efisiensi energi. Tetapi, jika dikaitkan dengan IPS, pemasangan lampu Light Emitting Diode (LED) perlu diperhatikan geometri pemasangannya. Penelitian ini membahas akurasi IPS pada Li-Fi apabila dengan berbagai bentuk geometri dan lokasi pemasangan lampu LED yang berbeda-beda. Teknik positioning Received Signal Strength (RSS) digunakan dengan mengambil kuat daya terima sebagai estimasi suatu jarak. Dengan membandingkan masing-masing bentuk geometri, maka didapatkan data konfigurasi terbaik untuk implementasi IPS. Hasil penelitian menunjukkan bahwa perbedaan jumlah lampu LED dan bentuk geometri akan berpengaruh terhadap akurasi positioning. Hasil menunjukkan bahwa geometri segi enam memiliki rata-rata error yang lebih kecil dibandingkan geometri yang lain, yakni sebesar 1,53×10?05m. Semakin banyak lampu LED atau poin referensi dengan rentang jarak lampu yang lebih rapat, maka dapat menghasilkan positioning yang lebih baik.

Group Work and Distance Online Learning in Higher Education – Reflecting on the Covid-19 Experience in the Natural Sciences
Authors: Rajendran Pillay
Published: July 2021

The sudden shift to online education at higher education institutions due to the Covid-19 pandemic had an impact on teaching and learning. For many the “new experience” meant learning or improving on the use of online technology in the distance mode. Although there have been many studies conducted on the impact of the pandemic on higher education, there is a paucity of research on specific pedagogies to mediate learning in the distance context, group work being one of them. This paper presents a reflective analysis of a case study in which group work was a pedagogical strategy used during the lockdown. Data collection involved questionnaires and a part transcript of a group’s mobile synchronous text chat. The data were analysed qualitatively and quantitatively for the open and closed questions, respectively. The findings reveal mobile phones as the most common technological device used, the specific challenge of data and internet access on group work success, and the professional benefit of developing social skills even in a distance online context. The study confirms that group work is a viable pedagogical strategy to mediate distance online learning which requires the expert guidance of the lecturer and reflection by group members to improve their distance online interactions.
Visualization of the Results of the Analysis of Programming Languages for Their Superficial Comparison
Authors: Gorodnyaya L. V.
Published: July 2021

The article is devoted to the choice of a clear and concise form for presenting the results of analise and comparing programming languages and systems, convenient for assessing the expressive power of languages and the complexity of implementing systems. The formalization is adapted to the paradigm analysis of the definitions of programming languages and the selection of practical criteria for decomposition of programs. The semantic decomposition of the definitions of languages and systems as part of the analysis of programming paradigms was chosen as the main ap-proach. Such a choice makes it possible to single out autonomously developed typical program components that can be adapted to the design of various information systems. Many works on methods for developing software systems depend on the practicality of approaches to decomposition of programs debugged using programming systems. The solution to this problem is useful when studying programming methods, studying the history of programming languages, for comparing programming paradigms, the potential of used circuits and models, assessing the novelty level of created programming languages, and also when choosing criteria for program decomposition. In addition, their existence allows us to form a teaching methodology for developing the components of information systems. Along the way, the distance in conceptual complexity between programming and programming system development is shown.
Correction of a Leaking Stoma: Using Silicone Block Insertion
Authors: Sung Ki , Lee Soo
Published: July 2021

BACKGROUND: Changes in abdominal contour, including peristomal indentations, can cause leakage of stoma effluent and other complications. PURPOSE: To describe the case of a 39-year-old patient with a urostomy who experienced very frequent urine leakage as a result of a peristomal indentation. CASE STUDY: The patient presented with a history of cystectomy and urostomy surgery for chronic interstitial cystitis and dysfunction of the bladder due to a neurogenic problem, and very frequent appliance changes due to urine leakage. Modest improvement occurred following fasciocutaneous V-Y advancement flap surgery. After 7 months, a silicone block was inserted in the peristomal indentation. After 1 year of follow-up, the outcome remained satisfactory and no additional procedures were needed. CONCLUSION: In this case, silicone block insertion was an effective and minimally invasive alternative to manage stomal leakage refractory to other procedures.
Marks of Ownership of Russian Far Eastern Book Collectors in the Late 19th — Early 20th Centuries
Authors: Radishauskayte Natalya V.
Published: July 2021

The Russian pre-revolutionary book features many various provenance marks including marks of ownership. Such marks indicate that a particular item belongs to a particular owner. They can have forms of supralibros (or super ex-libris), ex-libris (or bookplates), book stamps, signatures and inscriptions. There are also “non-specific” ownership stamps and labels, which do not have indications of their book nature (such as phrases “from the books/library of...”, “ex-libris…”) and can be used on any objects. Usually these are word rubber stamps (rarely — labels) with a text consisting of a book owner’s name and occasionally some additional information (such as an owner’s address, title, etc.). In Russia, bibliophiles and bibliologists have been studying bookplates for about two centuries. However, there are still many blank spots in the history of the Russian bookplate. Regional book ownership marks are mostly unexplored. This article presents an attempt to describe and analyse book ownership marks of the Russian Far Eastern book owners. Studying of library holdings of 13 regional institutions and conducting bibliographic research allowed revealing 58 local marks of ownership (excluding signatures and inscriptions) that belonged to 23 local book collectors of the pre-revolutionary period. The study showed that they used all types of marks from supralibros to inscriptions, but mostly preferred the “non-specific” book stamps and super ex-libris. There was also established that the bookplate labels were particularly rare — the author discovered the only specimen in the Far Eastern State Research Library. The predominance of book stamps as marks of ownership can be explained by their multipurposeness, cheapness and easiness of manufacturing. Far Eastern book owners frequently used two or three different types of marks together on one book, for example, book stamp and supralibros, inscription and book stamp or supralibros and inscription, etc. Often one collector used several different stamps or supralibros: almost 40% of book collectors had two or three marks of ownership. At the same time, 11 of 23 book owners additionally marked their books with the inscriptions.

Der Mix macht’s – Asynchron, synchron, inverted … von der Folienvertonung bis zum Experiment
Authors: Kruppke Benjamin
Published: July 2021

Die Übertragung klassischer Präsenz-Lehre in den digitalen Raum erfordert durch die veränderten technischen Randbedingungen meist zwangsläufig eine Auseinandersetzung mit den Lernzielen und den Methoden der Lehrveranstaltung. Im Zuge dessen wurden die Erfahrungen der zunächst erfolgten Umstellung auf asynchron bereitgestellte kommentierte PowerPoint-Präsentationen bis hin zu einem anschließend testweise durchgeführten dreiteiligen Vorlesungskonzept reflektiert. Dieses Konzept sieht eine Kombination aus 1.) asynchronen Vorlesungen mit kommentierten Präsentationen, 2.) synchrone Vorlesungen mit „klassischer“ Erläuterung von vorbereiteten Präsentationsfolien als Webmeetings und 3.) Vorlesungen nach dem Prinzip des Inverted Classrooms vor. Die Evaluation der verschiedenen Vorlesungsformen durch ein und dieselbe Gruppe an Studierenden zeigte eine selbstkritische Wahrnehmung des Inverted Classrooms als geeignetes Element zur selbstständigen, semesterbegleitenden und tiefgreifenden Beschäftigung mit den Lehrinhalten. Die weiterhin vollzogene Adaptierung einer Experimentalvorlesung im digitalen Raum belegte die Bedeutung von Audience-Response-Systemen zur Förderung der studentischen Wahrnehmung aktiv Einfluss auf die Veranstaltung nehmen zu können.
Lab@Home: Individualisierte Computerpraktika
Authors: Joswig Jan-Ole , Arnold Florian Max
Published: July 2021

Die im Jahr 2020 aufgetretene Pandemie bedingte auch an den Universitäten einen Lockdown und die Verlagerung der Lehre in den digitalen Raum. Im Bereich der Studiengänge Chemie und Lebensmittelchemie ist dies nur teilweise möglich. Insbesondere die Laborpraktika vermitteln Kernkompetenzen, die nicht anders als in Präsenz erworben werden können. Computerpraktika hingegen können mit guter Konzeption an den heimischen Computer verlagert werden. Wir stellen hier unser Konzept vor, das es möglich gemacht hat, Computerversuche aus den Bereichen der Quantenchemie und Statistischen Thermodynamik als Lab@Home-Computerpraktikum durchzuführen. Individualisierte Aufgabenstellung, kontrollierte Vorproduktion der numerischen Ergebnisse, fortlaufende Kommunikation mit den Studierenden und umfangreiche Nutzung digitaler Lehrmethoden waren dabei die entscheidenden Grundlagen für die erfolgreiche Durchführung.
(Wissenschafts-)Kultur der Digitalität
Authors: Lasch Alexander
Published: July 2021

Die Rede von der „Kultur der Digitalität“ ([7] Stalder 2019) sorgt in Universitäten regelmäßig für Unruhe. Der Titel löst dann Irritationen aus, wenn damit die Implikation verbunden ist, dass von einem Umbruch, von einer Ablösung auszugehen ist, dessen Folge es sei, dass die Universität, wie wir sie kennen, fortan nicht mehr existiere. Das Gegenteil ist der Fall – denn, wenn man das eine tun kann, bedeutet es nicht zugleich, dass man das andere lassen muss ([1] Lasch 2020). In meinem kurzen Beitrag möchte ich deshalb (1) das Konzept erläutern, es (2) auf unsere Communitas Universität übertragen und (3) ein Projekt vorstellen, das sich konsequenterweise genau dann etablieren kann, wenn man Universität als Universitas in einem umfassenden Sinn als Institution einer „(Wissenschafts-)Kultur der Digitalität“ versteht ([2] Lasch & Schoop 2021): „virTUos“ (Virtuelles Lehren und Lernen an der TU Dresden im Open Source-Kontext).

Published: July 2021

Die Einschränkungen in der Präsenzlehre sind insbesondere für experimentelle Wissenschaften wie die Physik eine besondere Herausforderung. In diesem Beitrag wollen wir einige Hilfsmittel und Konzepte vorstellen, die sich in der Ausbildung von angehenden Physiklehrer*innen bewährt haben. Wir werden getrennt auf die verschiedenen Veranstaltungsformen (Vorlesungen, Seminare, Praktika) eingehen und diskutieren, wie sie in einem Online-Format umgesetzt werden können. Tools wie Zoom, Ilias, Mural etc. können dabei insbesondere kooperative Lernformen unterstützen, die in der Online-Lehre besonders nützlich sind, um ein Mindestmaß an sozialer Interaktion zu gewährleisten. Außerdem stellen wir Konzepte vor, die zu einer reflektierteren Auseinandersetzung mit den Inhalten der Veranstaltung führen. Schließlich werden die Probleme bei Online-Prüfungen diskutiert, bei denen ein Kompromiss zwischen bestmöglicher Überwachung und der Wahrung der Privatsphäre gefunden werden muss.  Hier schlagen wir mögliche Lösungen vor, die sich bereits in der Praxis bewährt haben.

Vorstellung und studentische Evaluation digitaler Lernformate in zwei methodischen Grundlagenfächern der Mechanik
Authors: Bernstein David , Schuster Micha Sebastian , Beitelschmidt Michael
Published: July 2021

Die pandemiebedingte Umstellung der Präsenzlehre auf digitale Lernformate brachte vor allem für die Studierenden große Herausforderungen mit sich. Die beiden vorgestellten, methodischen Grundlagenfächer der Mechanik wurden vollständig digital angeboten. Zur Stoffvermittlung wurden aufgezeichnete Lehrvideos und zur Fragenbeantwortung vor allem Übungsforen eingesetzt. Mithilfe von Umfragen unter allen Prüfungsteilnehmenden wurden die eingesetzten Lernformate evaluiert. Es zeigt sich dabei, dass aufgezeichnete Vorlesungsvideos gegenüber Präsenzvorlesungen von den Studierenden als hilfreicher wahrgenommen werden. Als Vorteil wird dabei die Möglichkeit zum Anhalten und Wiederholen der Vorlesungsvideos genannt. Das Übungsforum wird zwar als eher hilfreich bewertet, jedoch nicht als adäquater Ersatz zur Präsenzübung eingeschätzt. Laut den studentischen Kommentaren spielt die direkte und unmittelbare Kommunikation in der Präsenzübung eine wichtige Rolle, die in einem Forum nicht erreicht werden kann. Die beste Bewertung unter den Lernformen erzielten kurze Einführungsvideos in die Thematik und Aufgaben der Übungen.

Published: July 2021

В статье обосновывается большое значение копирования произведений монументального искусства Древней Руси. Это позволяет сохранить изображения пусть даже в копиях, а в процессе копирования не только подробно изучить технологические и содержательные стороны фресковых циклов, но и, по мнению автора, формирует мировоззрение, дает возможность целостнее оценить духовный мир мастеров прошлого. Само копирование должно носить не фрагментарный характер, а комплексно охватывать всю систему росписей храма. Высококачественные копии фресок могут быть интересными экспонатами выставок и должны храниться как произведения искусства.

The article substantiates the great importance of copying works of monumental art of Ancient Rus. This allows you to save images even in copies, allows during the copy process, not only to study in detail the technological and content side of fresco cycles, but, according to the author, forms the world, allows integrity to assess spiritual world of the masters of the past.

Understanding students' use of mathematical processes during a digital escape game
Authors: Clune Megan
Published: July 2021

Mathematical processes have long been considered an essential component of meaningful learning in mathematics, yet these processes can sometimes be invisible in the mathematics classroom or in learning experiences. This discussion uses the context of a purpose-designed, innovative ‘digital escape’ game to illustrate how digital experiences might bring mathematical processes to the fore of student learning while offering other affordances only seen in the online space. This article reports on a pilot study conducted with 12-15-year-old school students with the aim of determining if a digital escape game could promote the use of mathematical processes. During the digital escape game, it was found that students engaged with problem-solving, reasoning, communication and made connections within, across and beyond mathematics. The preliminary findings demonstrate how digital experiences may enrich the use and development of core mathematical processes, and it is argued that teachers could use their own expertise and knowledge of their learners to design such experiences, catering to student needs and interests.

Дикарбоксилаты триарилвисмута p-Tol3Bi[OC(O)C6H3F2-2,3]2 (1) и m-Tol3Bi[OC(O)C6H3F2-2,3]2 (2) синтезированы по реакции окислительного присоединения между триарилвисмутом и 2,3-дифторбензойной кислотой в присутствии пероксида третичного бутила. По данным РСА атомы висмута имеют координацию искаженной тригональной бипирамиды с атомами кислорода карбоксилатных лигандов в аксиальных позициях. Аксиальные углы OBiO составляют 171.09(12)° (1) и 173.50(9)° (2). Длины связей Bi—C имеют близкие значения: 2.198(5)—2.213(4) Å в 1 и 2.165(3)—2.195(5) Å в 2, а расстояния Bi—O (2.261(3) Å, 2.306(3) Å в 1 и 2.284(3) Å, 2.243(3) Å в 2) соизмеримы с ковалентными длинами связей Bi—O. Атом висмута выходит из экваториальной плоскости [С3] на 0.007 Å и 0.012 Å в 1 и 2 соответственно. Расстояния Bi⋯O=C равны 2.878(5) Å, 2.953(4) Å (1) и 2.891(3) Å, 3.056(4) Å (2), что значительно меньше суммы ван-дер-ваальсовых радиусов атомов Bi и O 3.9 Å. Формирование пространственной структуры кристаллов соединений 1 и 2 обусловлено наличием водородных связей типа С=О⋯H, С(Ar)—Н⋯F, СН⋯π-вза­имодействиями и стэкинг-эффектом.
STEADY MHD MIXED CONVECTION NEWTONIAN FLUID FLOW ALONG A VERTICAL STRETCHING CYLINDER EMBEDDED IN POROUS MEDIUM
Authors: Sinha Sharad , Yadav R. S.
Published: July 2021

A viscous electrically conducting fluid is considered and its steady mixed convective flow along a vertical stretching cylinder is investigated. It is assumed that the cylinder is embedded in a porous medium and, external magnetic field, heat source/sink are also taken into account. Suitable similarity transformations are used to reduce the governing equations and associated boundary conditions into a system of nonlinear ordinary differential equations. This system along with the boundary conditions is solved by fourth order Runge-Kutta method with shooting technique. Variations in fluid velocity and temperature due to various physical parameters such as heat source/sink parameter, mixed convection parameter, magnetic parameter are presented through graphs. Effect of these parameters on dimensionless shear stress and rate of heat transfer are discussed numerically through tables.
Perceptions and experiences of community health workers on community-based child health interventions in the Maekel region, Eritrea
Authors: McDonald Jordanos T. , Trenholm Jill
Published: July 2021

Background

In 2015 alone, 5,9 million children under the age of five died. In an attempt to reduce child mortality in Eritrea, the government implemented community- based child health interventions by community health workers (CHWs). Despite progress, challenges remain. In Eritrea, few studies have examined CHWs and community perceptions of child health interventions. The aim of this study was to explore the perceptions of CHWs regarding benefits and challenges of community-based child health interventions in the Maekel region in Eritrea.

Methods

An explorative qualitative study was conducted employing focus group discussions. Data was analyzed using qualitative content analysis.

Results

The CHWs reported positive aspects such as easier access to health services, generated relationships and support and opportunities to give back to the community. Perceived challenges were: constraints in delivering services, resources and supervision, inadequate knowledge and awareness and juggling multiple roles with no pay. The ministry of health (MoH) in Eritrea prioritizes reducing child mortality but, is still in the process of building and stabilizing the healthcare system. The biggest challenge is to incorporate community level Integrated Management of Childhood Illnesses and Case Management (C-IMCI/iCCM), involving communities, families and CHWs into the current system of limited resources.

Conclusions

This study indicates the importance of focusing on identifying solutions to the challenges the CHWs faces and understanding factors associated with CHWs motivation. This with the hope of better effectiveness and sustainability of the C-IMCI/iCCM program.

Learning communities have a positive impact on the development of the pedagogical competence of prospective mathematics teacher students. However, the nature of competition between students is more dominant in universities. This study aims to develop a valid and practical lesson study for learning community-based learning environments to improve the pedagogical competence of student mathematics teacher candidates. This study used the Rowntree model development research design and Tessmer's formative evaluation model, including self-evaluation, expert review, one-to-one evaluation, and small group evaluation. Data collection techniques used walkthrough, observation, documentation, questionnaires, interviews, and tests. The results showed that the learning environment based on the lesson study for the learning community that was developed had met valid and practical criteria and had a potential effect in improving the pedagogical abilities of student mathematics teacher candidates. Based on data analysis, the pedagogical competence of most of the students was good, with details: 94.16% of students had the competence to prepare a good lesson plan. The competence to carry out learning activities well has been mastered by 91.66% of students. Meanwhile, the understanding of the lesson study for the learning community has reached 82.5%. These results indicate that the learning community among fellow students as a lesson study for learning a community-based learning environment can improve the pedagogical competence of student mathematics teacher candidates.

Mathematics school exams as summative assessments are expected to have good quality, so the description of students' abilities is under the actual conditions. However, due to COVID-19, math school exams are carried out online, which results in bad quality of instruments, so analysis of math exam questions is needed for information about the quality of questions, and an overview of students' abilities is obtained. This study aimed to analyze the quality of the questions, which included analyzing the characteristics items seen from the level of difficulty, differences, distractions, and estimation of students' abilities with the item response theory approach. This study employs a quantitative research method with an exploratory, descriptive approach. The subjects of this study were 758 grade 9 students of State Junior High School who took mathematics school exams in Gunung Jati Sub-district, Cirebon Regency. Data from student's responses or answers from mathematics exam questions in the form of multiple-choice with 40 items for the 1st school, 35 for the 2nd school, and 20 for the 3rd school. The research data fulfills the IRT's assumptions first. Then, the researchers found that from the online assessment analysis with SPSS software, the R and Ms. Excel program, it showed that the level of difficulty there were still some items that needed to be revised or removed if not needed. The difference between the items in the three schools could be said to be good even though the distribution was not evenly distributed. The effectiveness of the distractor is more dominant in having a bad distractor with a percentage of 100% and 65.7% and the ability of students to answer math exam questions by obtaining the highest ability information from different students from the three schools.
