Authors: Veeranaath V. , Daga Uddhav , Kumar Yuvraj
Published: March 2023

Magnesium-based materials are in superior demand in auto industries due to their improved properties and behavior. However, processing and further post-treatment of this kind of magnesium composite is a stimulating chore because of its characteristics. In particular, heat treatment of this kind of magnesium composites may induce a change in grain structure which in turn alters the properties according to the need. So, this article is chiefly focused on the fabrication of magnesium composites by filling with SiC and graphite. According to the Taguchi array, the composites were developed by altering the reinforcing material content, stirring period, and rate. Four samples were fabricated accordingly by employing the stir casting technique. The fabricated composites were exposed to diverse forms of heat treatment processes such as annealing, normalizing, tempering, and quenching to learn the upshot of the same on its behavior. The surface structure of the dispersions in the developed composites was analyzed using an optical microscope, and the mechanical and physical behavior like strength, density, wear, and tensile tests were done on the developed samples. The morphology and behavior of the fabricated composites were compared and analyzed pre and post-heat treatment. Keywords. Magnesium Hybrid Composites, Stir Casting, Heat Treatment.

Published: March 2023

Recycling of construction material helps to conserve the limited landfill spaces and increase the gained cost. Among various types of materials timber and concrete & masonry waste were the most generated waste at construction sites. The recycling practices at construction sites reduces the generation of C&D waste and increase the gained cost. Therefore, this paper aimed to investigate the total recycled C&D waste and gained amount between two different construction sites. The data was collected over 6 months period using direct and indirect measurement. The paper revealed that the gained cost for Site I is RM 29,880.90 while for site II is RM 38,217.80. The CBA revealed that it was positive for these projects with benefits of RM 360.90 and RM 927.80 respectively. This paper provides an awareness for contractors regarding costings that can be gained if the C&D waste was adequately managed. Thus, it directly benefits the construction industry in terms of economic sustainability for a construction project

The influence of the processing route on the microstructure characteristics and mechanical properties of high-entropy carbides was investigated. The experimental materials were prepared by a combination of ball milling and spark plasma sintering at the temperature of 2100 °C. The effect of sintering time (5 min, 10 min, and 20 min) on the microstructure development and properties of the investigated systems has been studied. The microstructure analysis was performed using scanning electron microscopy + EDAX analysis on the polished surfaces. Nanoindentation was used for the nano-hardness and Young’s modulus measurements. Micro-hardness was measured using Vickers method and indentation method using a Vickers indenter was used to determine the indentation fracture resistance – fracture toughness. The measured grain size values were in the range from 5 µm to 14 µm. The nano-hardness values changed from 36 GPa to 39 GPa and the indentation modulus of elasticity from 558 GPa to 577 GPa, respectively. The measured micro-hardness values were in the range from 18.93 GPa to 21.95 GPa and the indentation fracture resistance changed from 2.70 MPa.m1/2 to 3.50 MPa.m1/2, respectively.

Published: March 2023

This paper deals with the formation of sulphides in as-cast grain-oriented electrical steel (GOES) thin strip during solidification and subsequent cooling through the (δ + γ) field. Chemical composition of the strip was as follows, in mass %: 0.034 C, 2.81 Si, 0.06 Mn, 0.024 S, 0.20 Cr, 0.15 Cu, 0.055 Ni, 0.0011 Ti, 0.0056 N and 0.002 Al. It was found out that chemical composition of coarse sulphides, formed in the area of final solidification, was very different from the composition of fine sulphides precipitated in the two-phase region. Coarse sulphides were rich in iron. Fine complex sulphides were identified as the Cr2CuS4 phase. The effect of fine sulphides on the austenite decomposition at the end of the (δ + γ) field was studied.

Published: March 2023

Fiber reinforced polymer materials have been used as the alternative to conventional steel reinforcement within the construction industry. While Basalt fiber reinforced polymers (BFRP) have shown improved mechanical properties and durability performance compared to conventional steel, it is not immune to degradation and corrosion when subjected to harsh environments. As such, significant studies have been conducted to simulate the mechanical properties of BFRP bars under degradation when subject to different hostile substances. However, there is no standardized conclusion for the performance of BFRP under an acidic environment and in-depth microstructure evaluation as the degradation of BFRP is influenced by myriad factors. This study aimed to produce a Response Surface Methodology (RSM) model to study the effect of pH, temperature, and immersion time on the tensile strength and elastic modulus. Data from existing literature involving acid emersion of BFRP were collected and modelled using RSM to present an overview of the degradation behavior of BFRP. In addition, a synthesis of the microstructure of BFRP reinforcing bars exposed to the acidic environment was evaluated by referring to SEM and EDX. It was concluded that the tensile strength loss due to corrosion was affected by temperature and immersion time in a linear function. On the other hand, tensile strength drop occurred exponentially as an acid with higher pH was used. Hence, the paper revealed the influence of various factors on the corrosion rate of the BFRP rebar.

Published: March 2023

Introduction: Diverticulosis and diverticular disease (DD) is a common occurrence in clinical practice in the local setting with a lack of documented literature. A snapshot audit was conducted at North Colombo Teaching Hospital (NCTH) to ascertain the disease burden in clinical practice as a pilot study to assess feasibility and response rate for a nation wide snapshot audit.
Methodology: All surgical and gastroenterology units at NCTH were requested to enter the data between 1st January 2022 to 30th of June 2022 on all patients presenting with DD or those detected with diverticulosis during screening colonoscopy. Prospective data collection was done using RedCap© data capturing platform.
Results: Out of the 8 units invited (general surgery – 5, GI surgery – 1, gastroenterology – 2), 5 units participated (general surgery – 2, GI surgery – 1, gastroenterology – 2); response rate is 62%. A total of 46 patient records (median age- 68 years; range 29- 86; female 51%) were received within 6 months. Of the total 54.3% had symptomatic uncomplicated diverticular disease (SUDD) while 33% were detected with diverticulosis at screening. Only 13% (n=6) required inward care (bleeding – 3, diverticulitis – 2, perforation – 1) and detected using colonoscopy in 4 and CT scan in 2. In the DD group, 20% (6/31) had complicated DD while 80% had Symptomatic Uncomplicated Diverticular Disease (SUDD).
Conclusion: In this pilot study, a majority of the patients with DD presented with SUDD while around 20% came with complicated DD. The response rate from collaborators was satisfactory. The secure online database usage is feasible and will be used for a national level study in the future to assess the disease burden in the healthcare setting in Sri Lanka.
IL-12 and IL-27 Promote CD39 Expression on CD8+ T Cells and Differentially Regulate the CD39+CD8+ T Cell Phenotype

Published: March 2023

Tumor-specific CD8+ T cells are critical components of antitumor immunity; however, factors that modulate their phenotype and function have not been completely elucidated. Cytokines IL-12 and IL-27 have recognized roles in promoting CD8+ T cells’ effector function and mediated antitumor responses. Tumor-specific CD8+ tumor-infiltrating lymphocytes (TILs) can be identified based on surface expression of CD39, whereas bystander CD8+ TILs do not express this enzyme. It is currently unclear how and why tumor-specific CD8+ T cells uniquely express CD39. Given the important roles of IL-12 and IL-27 in promoting CD8+ T cell functionality, we investigated whether these cytokines could modulate CD39 expression on these cells. Using in vitro stimulation assays, we identified that murine splenic CD8+ T cells differentially upregulate CD39 in the presence of IL-12 and IL-27. Subsequently, we assessed the exhaustion profile of IL-12– and IL-27–induced CD39+CD8+ T cells. Despite the greatest frequency of exhausted CD39+CD8+ T cells after activation with IL-12, as demonstrated by the coexpression of TIM-3+PD-1+LAG-3+ and reduced degranulation capacity, these cells retained the ability to produce IFN-γ. IL-27–induced CD39+CD8+ T cells expressed PD-1 but did not exhibit a terminally exhausted phenotype. IL-27 was able to attenuate IL-12–mediated inhibitory receptor expression on CD39+CD8+ T cells but did not rescue degranulation ability. Using an immunogenic neuro-2a mouse model, inhibiting IL-12 activity reduced CD39+CD8+ TIL frequency compared with controls without changing the overall CD8+ TIL frequency. These results provide insight into immune regulators of CD39 expression on CD8+ T cells and further highlight the differential impact of CD39-inducing factors on the phenotype and effector functions of CD8+ T cells.
Factors influencing maternal-fetal attachment in pregnant women during the COVID-19 pandemic: a cross-sectional study
Authors: Yoon Hyeryeong , Choi Hyunkyung
Published: March 2023

Purpose: Coronavirus disease 2019 (COVID-19) has spread widely throughout the world, causing psychological problems such as fear, anxiety, and stress. During the COVID-19 pandemic, pregnant women have been concerned about both their own health and the health of their fetuses, and these concerns could negatively affect maternal-fetal attachment. Thus, this study aimed to explore the level of COVID-19 stress, resilience, and maternal-fetal attachment among pregnant women during the COVID-19 pandemic, and to identify factors influencing maternal-fetal attachment.Methods: In total, 118 pregnant women past 20 weeks gestation were recruited from two maternity clinics in Daegu, Korea, to participate in this descriptive correlational study during COVID-19. The factors influencing maternal-fetal attachment were analyzed using hierarchical multiple regression analysis.Results: The mean scores for COVID-19 stress, resilience, and maternal-fetal attachment were 57.18±10.32 out of 84, 67.32±15.09 out of 100, and 77.23±9.00 out of 96, respectively. Nulliparous pregnant women reported greater maternal-fetal attachment than multiparous pregnant women (p=0.03). Religious pregnant women also reported greater maternal-fetal attachment than non-religious pregnant women (p=.039). Resilience (β=.29, p=.002), COVID-19 stress (β=.20, p=.030) and parity (β=–.17, p=.047) were factors influencing maternal-fetal attachment, and these factors explained 26.4% of the variance in maternal-fetal attachment (F=10.12, p<.001). Conclusion: Converse to common sense, COVID-19 stress exerted a positive influence on maternal-fetal attachment in pregnant women during the COVID-19 pandemic. Healthcare providers need to recognize the positive influence of COVID-19 stress and implement intervention strategies to strengthen resilience in pregnant women to improve attachment with their fetuses.

Published: March 2023

The hydropericardium in chickens is most common in Isfahan and Chcharmahal-va-Bakhtiyari, Iran. For this, the study was achieved for investigation of adenovirus role in induction of hydropericardium in these regions. In this study, 20 broiler flocks suspected to hydropericardium were sampled from hydropericardium fluid. Then, DNA was extracted and amplified by specific primers. The amplified fragment for detection of AV was 896 bp. The results showed that 10 in 20 flocks, and 47 in 200 samples were positive to AV. The results revealed that most of infected flocks were more than 30 days old. In this study, the correlation between infectivity to adenovirus and husbandry system were not significant. The infectivity rate in Isfahan and Chaharmahal-va-Bakhtiyari was not significant. Therefore, in addition to high altitude, adenovirus infection can play a role in increasing the prevalence of hydropericardium in these areas.

Background: The most common post-operative symptoms are nausea and vomiting. Aromatherapy has been shown to reduce post-operative nausea and vomiting and thus could be used as a complementary therapy to antiemetic drugs; however, no studies have considered the exclusive use of Lavender in these patients. The study’s aim is to assess aromatherapy in reducing nausea and vomiting in post-operative patients. Materials and Methods: A 2-arm randomised controlled interventional study was carried out in the Neurosurgery, General Surgery, Vascular Surgery, and Gynaecology facilities of the SS Antonio e Biagio e Cesare Arrigo Hospital of Alessandria. Study inclusion criteria: patients over the age of 18, who sign an informed consent form, have had an anaesthesiologic examination, have had general anaesthesia, and are clinically stable with a nausea score of NRS>0. Multiple instruments will be used, including a numerical rating scale, a Likert rating scale, and a Likert rating scale to assess Vomiting and the degree of satisfaction. Conclusions: The use of complementary non-pharmacological methods such as aromatherapy may help patients feel more comfortable in the post-operative period.

The incidence aortic valve injury during percutaneous coronary intervention is scarce, mostly resulting in acute aortic regurgitation. However, rarely patients may remain asymptomatic in the immediate post-procedure period and present latter with chronic aortic regurgitation. Determining etiology of such an aortic regurgitation may be challenging. We present a case of a 51-year-old man with history of percutaneous coronary intervention for coronary artery disease and moderate aortic regurgitation scheduled for coronary artery bypass grafting and aortic valve replacement. Intra-operative transesophageal echocardiography was instrumental in deciding etiology of aortic regurgitation that change surgical management of the patient.

Published: March 2023

Myocardial abscess is a suppurative infection of myocardium, endocardium, native or prosthetic valves, perivalvular structures and cardiac conduction system. It develops in about 20% of patients with infective endocarditis. Due to avascular and fibrous structures, valvular regions are commonly involved. More precisely, aortic valve (AV) rings area; native or prosthetic valve is usually affected. Occurrence of myocardial abscess within free wall of the left ventricle (LV) without any evidence of infective endocarditis is a rare phenomenon; and infrequently reported in medical literature. We report a case of myocardial abscess cavity within the anterior wall of the LV, in a patient who underwent open heart surgery for severe AV stenosis. This was an incidental intraoperative transesophageal echocardiography (TEE) finding without any other evidence of infective endocarditis. The stenotic AV was replaced, along with surgical drainage and closure of the cavity. Postoperatively, patient was managed on empirical antibiotics according to infective endocarditis guidelines.

Published: March 2023

Hemolytic anemia and right ventricular outflow tract obstruction following device closure of ruptured sinus of Valsalva have seldom been reported in isolated case reports, and exact incidence is not known. A gentleman presented with severe delayed hemolytic anemia following the use of cocoon duct occluder for ruptured sinus of Valsalva. Right ventricular outflow tract obstruction of unclear etiology was also reported on transthoracic echocardiography, necessitating retrieval of the device and surgical closure of the defect. Intraoperative transesophageal echocardiography (TEE) showed right ventricular outflow obstruction by the cocoon device itself with a normal pulmonary valve. In this report, we emphasize that improper device selection for closure of ruptured sinus of Valsalva aneurysm, may lead to delayed leaks across the device, which can gradually progress causing hemolytic anemia and high gradient across the right ventricular outflow tract. Intraoperative TEE helped to delineate the cause of right ventricular outflow tract obstruction.

Once regarded as a rare complication, the potentially fatal bone cement implantation syndrome (BCIS) has been increasingly reported. BCIS can present as transient desaturation, hypotension, cardiac dysrhythmias, and cardiovascular collapse. Diagnosis of BCIS is often clinical and confirmed with computed tomography (CT) imaging postoperatively. However, point of care ultrasound (POCUS) examination could be a helpful and timely tool to clinch the diagnosis in a sudden cardiovascular collapse. We present a case of Grade 3 BCIS where POCUS examination revealed a massive clot in the right atrium, which supports the diagnosis.

Can Donor Demography or Anthropometry be Used as a Screening Tool for Identifying Potential Low ABO-Titer Plasma?
Authors: Ranjan Shweta , Pandey Prashant , Setya Divya , Kumari Supriya
Published: March 2023

Background and Aims:

Titration is a time-consuming procedure even when automated. The aim of the present study was to identify the variation in ABO titers with donor characteristics in Group O individuals.

Materials and Methods:

This was a prospective, observational study conducted from January 2019 to March 2020. All consecutive O group donors were included. All samples were tested by conventional tube technique (CTT). Demographic and anthropometric details of the donors such as gender, age, religion, height, weight, first-time/repeat donor, and state of residence were recorded. The high-titer group included individuals with anti-A and anti-B ≥128, and the low-titer group included individuals with anti-A and anti-B <128.

Results:

A total of 2000 Group O whole blood donors were included. A higher percentage of donors were older than 30 years of age (55.3%), males (90.7%), Hindu (87.15%), belonging to Uttar Pradesh (70.85%), height more than 160 cm (88.85%), weight more than 65 kg (82.2%), body mass index (BMI) more than 23 (86.15%), body surface area more than 1.7 m2 (89.95%), and first-time donors (68.4%). The donor age, height, weight, BMI, and body surface area were found to have a weak correlation with anti-A and anti-B titers performed by CTT. The correlation between female and male gender was poor in high- as well as low-titer category.

Conclusion:

A definite variation in antibody titers is seen with a change in donor demographics and anthropometrics. However, none of the variables helps as a screening tool for identifying the North Indian healthy donors who possess a high or low titer.

Published: March 2023

Background:

This cross-sectional study was performed with the aim of determining the prevalence of hepatitis E virus (HEV) infection among acute hepatitis patients attending a tertiary care teaching hospital in a developing country and to determine the relative performance of prevalent diagnostic assays in establishing its diagnosis.

Materials and Methods:

A total of 46 adult patients were included in this study, all of whom presented with jaundice of <4 weeks’ duration and elevation of AST and ALT above 500 U/L. The prevalence of HEV among patients with acute hepatitis was calculated on the basis of the proportion of recruited patients reacting positively in serum anti-HEV immunoglobulin M (IgM) and real-time polymerase chain reaction (RT-PCR) assays.

Results:

Among the recruited patients, 11 (23.91%) and 15 (32.6%) patients were positive for anti-HEV IgM and RT-PCR, respectively. The two tests demonstrated poor inter-test agreement, thereby implying the necessity of performing both tests for reliable diagnosis of acute HEV virus infection. We also observed a significant difference in the duration of illness between RT-PCR positive and negative patients (P = 0.008). The mean (±SD) duration of illness in the two groups was 8.6 (±3.50) and 11.66 (± 5.15) days, respectively. Combining the results of IgM ELISA and RT-PCR, we observed that 23 out of 46 patients (50%) had evidence of acute HEV virus infection among our patients.

Conclusion:

Our study suggests that HEV is the commonest cause of acute hepatitis in adult patients attending a tertiary care teaching hospital and that the diagnostic algorithm for its confirmation should include both IgM ELISA and RT-PCR assays.

Published: March 2023

Introduction:

Cost-analysis can help hospital administrators and policy-makers to determine how well their institution meets this public need. As financial management technique, cost-analysis helps to furnish the necessary data for making more informed decision on operations and infrastructure investments. Keeping this in mind, a study to estimate the cost spent by heroin-dependent patients before and after availing treatment for substance use disorder in a defined study population was conducted in National Drug Dependence Treatment Center (NDDTC), Ghaziabad.

Methodology:

A descriptive observational study conducted in outpatient department (OPD) of NDDTC on Male, heroin-dependent patients seeking treatment from NDDTC OPD, Ghaziabad.

Results:

The median of total expenditure incurred by patients on substance use (considering procurement of substance, transport, and lost productivity) before coming to treatment was Rs. 527/day. The median of total expenditure incurred by patients after initiating treatment at NDDTC (considering continued substance, transport to NDDTC, lost productivity, and purchasing medicines from outside) was Rs. 34/day. Thus, amount saved by the patients after starting treatment was Rs. 492.62/day. Even after considering the expenses incurred by the NDDTC in treatment, amount saved is Rs. 445.04/day.

Conclusion:

This study successfully demonstrated that even after adding the expenditure by the NDDTC to the expenditure by the patients on the treatment, treatment at NDDTC does result in a considerable reduction of overall costs. This is an indirect pointer towards cost-benefit of drug treatment.

The purpose of this study was to evaluate the relationship between the presence of pneumonia and blood parameters in casesof Coronavirus disease (COVID-19) and to examine their predictive characteristics in terms of pneumonia. We reviewed the filerecords of 151 pediatric patients with a diagnosis of COVID-19 confirmed by the real time-reverse transcription polymerase chainreaction test in nasopharyngeal swabs. The patients were divided into two groups based on direct chest X-ray and computedtomography results in [Group 1 (n:41), with pneumonia findings, and Group 2 (n:110), with no pneumonia findings]. The groups’demographic data, clinical and laboratory findings were compared. Pulmonary involvement was determined in 41 (27.1%) ofthe 151 patients. The [body mass index (BMI) Z-score], red blood cell distribution width (RDW), mean platelet volume (MPV),neutrophil lymphocyte ratio, passive leg raise, and D-dimer levels were significantly higher in patients with pneumonia than thosewithout pneumonia in our study. Based on multivariate logistic regression analysis, BMI Z-score, MPV, and RDW were found tobe independent risk factors of pneumonia in patients. The current study showed higher levels of blood parameters in patients withcoronavirus disease 2019 (COVID -19) presenting with pneumonia than those without pneumonia. We suggest that BMI-Z scoreand MPV value may assist in predicting pulmonary involvement in patients with COVID-19.

Em primeiro lugar, realizam-se esforços no sentido de esclarecer o que se entende por conceito unitário de autoria, especialmente à luz do ordenamento jurídico-penal austríaco e da Lei de Contraordenações alemã, em contraposição ao Código Penal da Alemanha, que adota um conceito diferenciador. Conclui-se que o conceito unitário de autoria representa apenas uma designação tautológica para autoria e participação, como mero veículo de atribuição da mesma consequência jurídica que se confere à autoria em sentido estrito à participação stricto sensu. Na sequência, a partir da discussão de casos hipotéticos, são demonstradas e criticadas as consequências jurídicas da adoção de um conceito unitário de autoria. As principais são o esvaziamento do conceito de autor e a pobreza categorial que impossibilita apreender como diferentes formas de intervenção no delito as diferentes estruturas de um evento lesivo de um bem jurídico no qual participam mais de uma pessoa. Ao final, discutem-se criticamente algumas manifestações da concepção unitária na legislação e na jurisprudência alemãs.

Authors: Айнутдинов А.С.
Published: March 2023

В статье рассматривается реформирование Оргбюро Уральского Союза советских художников в Свердловский Союз советских художников. С помощью историко-генетического метода описывается изменение его организационной структуры и кадрового состава. Кроме этого, опираясь на системный метод, автор продемонстрировал зависимость событий внутри союза от общественно-политических и культурных мероприятий и процессов, происходивших в СССР в период 1934–1935 годов, среди которых главное место занимали убийство С.М. Кирова и «Кремлевское дело». С использованием биографического метода в статье также дано краткое описание жизни Николая Александровича Виницкого, второго председателя творческой организации художников в Свердловске. Все архивные источники, использовавшиеся для выполнения этих задач, вводятся в научный оборот впервые.

The article discusses the reformation of the Organizing Bureau of the Ural Union of Soviet Artists into the Sverdlovsk Union of Soviet Artists. The historical-genetic method made it possible to describe the change in its organizational structure and staffing. Also, the author, relying on a systematic method, demonstrated the dependence of the internal events of the Union on socio-political and cultural events and processes in the USSR in 1934–1935, the most significant of which was the murder of S.M. Kirov and the “Kremlin Affair”. Using the biographical method, the article also gives a brief description of the life of Nikolai Alexandrovich Vinitsky, the second chairman of the creative organization of artists in Sverdlovsk. All archival sources used to conduct this study on the history of the art of the Urals are introduced into scientific circulation for the first time.

Authors: Горкина А.В.
Published: March 2023

В статье рассматривается петербургская академическая пейзажная живопись второй половины XX столетия. Автор использует материалы научного и фотоархивов Российской академии художеств, а также Российского государственного архива литературы и искусства. Изучается послевоенный период, когда возобновлению и развитию традиционных связей русских и итальянских художников способствовали выдающиеся мастера, выпускники и преподаватели Института живописи, скульптуры и архитектуры имени И.Е. Репина — Андрей Андреевич Мыльников, Пётр Тимофеевич Фомин и Юрий Михайлович Непринцев. Устанавливается влияние культурного наследия Италии на пейзажное творчество этих мастеров. Рассматриваются как стилистические, так и технические подходы в передаче образов Апеннинского полуострова. Освещаются поездки ленинградских художников в Италию, среди которых — посещение творческой базы Академии художеств СССР в Риме, творческие командировки от АХ СССР и от Союза художников, персональная выставка А.А. Мыльникова в Венеции. Также изучаются впечатления мастеров и выявляются их творческие связи. Подчеркивается значение культурного диалога между Италией и СССР, анализируется роль пленэрной и этюдной живописи для развития пейзажного жанра в ленинградском академическом изобразительном искусстве.

The focus of the article is Petersburg academic landscape painting of the second half of the 20th century. The author is based on the materials of the scientific archive of the Russian Academy of Arts and the Russian State Archive of Literature and Art, as well as on the illustrative base of the photo archive of the Russian Academy of Arts. The author studies the post-war period, when the resumption and development of traditional contacts between Russian and Italian artists were promoted by outstanding masters, graduates and teachers of the Repin Academic Institute of Painting, Sculpture and Architecture. Among them were such artists as A.A. Mylnikov, P.T. Fomin and Y.M. Neprintsev. The study reveals the influence of the cultural heritage of Italy on the landscape art of these masters. Various stylistic and technical approaches to the transfer of images of the Apennines are considered. Key points in this context are the trips of Leningrad artists to Italy, their impressions of this country and established connections. These are events such as visits to the creative base of the USSR Academy of Arts in Rome, creative business trips from the USSR Academy of Arts and the Union of Artists, as well as a personal exhibition of A.A. Mylnikov in Venice. The author emphasizes the importance of cultural dialogue between Italy and the USSR, the role of plein air and sketch painting.

Authors: Sari Beatrix Purnama
Published: March 2023

Penelitian ini bertujuan untuk mendeskripsikan karakter miskonsepsi siswa dan penyebabnya pada materi Sistem Persamaan Linier Dua Variabel (SPLDV) yang ditinjau dari gaya belajar siswa. Jenis penelitian yang digunakan dalam penelitian ini adalah penelitian Deskriptif, dengan pendekatan penelitian yaitu deskriptif kualitatif. Subyek penelitian yaitu siswa kelas VIII SMP Kristen 1 YPK Malang. Teknik pengumpulan data yang digunakan adalah metode ob-servasi, angket, tes dan wawancara. Hasil penelitian menyatakan siswa yang memiliki gaya belajar auditorial lebih banyak memiliki karakter miskonsepsi dan kelemahan dalam memecahkan masalah SPLDV dibandingkan siswa yang memiliki gaya belajar visual dan kinestetik. Sedangkan yang memiliki karakter miskonsepsinya sedikit dibanding yang lain adalah pada siswa yang memiliki gaya belajar kinestetik. Penyebab miskonsepsi yang sama pada ketiga gaya belajar yaitu berasal dari guru dan siswa itu sendiri. Guru menjadi penyebab miskonsepsi karena konsep SPLDV yang disampaikan tidak semua dipahami dan siswa juga kurang memberi perhatian kepada penjelasan guru dan jarang mengungkapkan kesulitan kepada guru karena takut. Untuk itu guru dapat menggunakan model dan metode pem-belajaran yang sesuai untuk penanaman konsep dan menyesuaikan dengan gaya belajar siswa sehingga dapat meminimalisasi miskonsepsi yang terjadi pada siswa.
Book Review: The Development of Chinese Education in Malaysia
Authors: Tek Yoong Chin
Published: March 2023

The book “The Development of Chinese Education in Malaysia”, authored by Tan Yao Sua, published in 2021 by Strategic Information and Research Development Centre, Petaling Jaya. This book’s publication is considered relevant since it will help to provide an overview of how Chinese mother tongue education has evolved through time. Currently, the majority of scholarly works that discuss historical issues and the development of Chinese mother tongue education are published in Chinese language, making them inaccessible to readers who do not speak or comprehend the language. For readers who can understand Chinese, their exposure to reading materials that touch on historical issues and the development of Chinese mother tongue education in languages other than Chinese can certainly give them a more comprehensive picture. Indeed, the reader’s perception can certainly avoid the sense of punishment that is pushed outside of the narrow and assumed ethnic scope. It is also appropriate as scholarly reference material for researchers who specialize in Chinese mother tongue education as well as readers from all walks of life who are curious about the background of Malaysia’s Chinese mother tongue education system.
