Authors: Pamintuan Cavin F.
Published: May 2024

This mixed-methods explanatory sequential research investigated the Pedagogical Content Knowledge (PCK) cognitions and practices of Filipino high school teachers of Mandarin. The PCK framework highlights the crucial interplay between pedagogical and content knowledge, aiding educators in selecting the most suitable teaching techniques to effectively present the subject matter. This study combined both quantitative and qualitative data from self-assessment reports, semi-structured interviews, and classroom observations, providing a clear picture of the participants’ PCK. Using descriptive statistics and thematic analysis, this study fully captured the participants’ PCK. The qualitative data revealed that the participants' confidence level on their pedagogical content knowledge was considered high. While the qualitative data uncovered the participants’ eighteen PCK practices, and their cognitions on the significance of using appropriate techniques to maintain motivation, achieve lesson’s objectives, cater students’ needs, and bridge challenges in teaching Chinese Mandarin. Lastly, anchored from the findings, this study provided recommendations such as deepening the participants’ understanding of the PCK framework and strengthening each professional knowledge, contributing to improving the participants’ capability to effectively teach Mandarin.

Authors: Kharina A. V. , Savintseva L. S.
Published: May 2024

The review presents up-to-date information on the genes of resistance of soft wheat (Triticum aestivum L.) to Septoria blight (STB), the causative agents of which are Zymoseptoria tritici, Paras- tagonospora nodorum, Mycosphaerella graminicola. The main attention is paid to the genetic control of wheat resistance to septoria blight from the point of view of the quantitative and qualitative nature of resistance and its effectiveness. The successes achieved so far in the identification of genes and loci of quantitative wheat traits associated with resistance to Z. tritici and P. nodorum are summarized. The characteristics of 15 genes of resistance to septoria blight and the most commonly used molecular markers are given. The data on the varieties with the most effective STB resistance genes are presented: Bulgaria 88, Oasis, Sullivan, Veranopolis, Chinese spring, Tadinia, Flame, Hereword, Curtot, Tonic, Kavkaz-K4500, Arina, Riband, Balance, Apach. Promising markers, mainly microsatellites, or simple sequence repeats (SSR), are recommended for use in breeding for T. aestivum L. resistance to septoria blight. It is technically difficult to use fragment length polymorphisms (AFLP) as molecular markers of resistance genes of cultivated plants. As new resistance genes are discovered and mapped, information about the possibility of pyramiding Stb genes in the breeding material is being updated. The combination of several genes in the genome increases the stability of the variety, since the activity of the genes against STB is manifested at different stages of plant development. The use of known genes in marker-mediated wheat selection and the search for new resistance genes will allow to obtain stable yields with minimal use of pesticides.

Authors: Grebennikova I. G. , Chanyshev D. I.
Published: May 2024

The results of the study of architectonics and physical and mechanical properties of the stems of selective forms of spring hexaploid triticale of different ecological and geographical origin are presented. Traits of 19 collection and breeding samples from the collections of the N.I. Vavilov All-Russian Institute of Plant Genetic Resources (VIR) and the Siberian Research Institute of Plant Growing and Selection - branch of the Federal Research Center of the Institute of Cytology and Genetics of the Siberian Branch of the Russian Academy of Sciences (SibNIIRS – branch of the Institute of Cytology and Genetics of the Siberian Branch of the Russian Academy of Sciences) served as research objects. Macrometric parameters were studied on 25 representative specimens of each breeding sample when they reached the phase of full ripeness during three years (2021–2023). The resistance of the stem to bending or fracture was determined on an experimental specimen manufactured at the SibNIIRS with a stable platform, bars for fixing the specimen and a slot for placing a dynamometer. The susceptibility of triticale plants to lodging was evaluated by a set of traits: weight of a 10-cm straw of the 2nd internode; stem resistance to breaking determined by the peak reading of an electronic dynamometer; stem tissue density of the 2nd internode. The studied samples differed significantly in these parameters and were characterized by different degrees of the resistance to lodging. Promising breeding specimens that can be used as sources of valuable traits have been identified based on the totality of the strength parameters. Application of the principal component method allowed to identify the marker trait "sum of lengths of the 2nd and 3rd internodes", which was determinant in providing high lodging resistance in the studied samples. A close relationship between the trait of 10-cm straw mass of the 2nd internode and the parameter of the stem resistance to breakage has been established. The conjugation of these characteristics will make it possible to identify the sources of valuable traits and purposefully carry out the selection process of triticale for resistance to lodging without attracting short-stemmed forms.

In the course of the experiment, the influence of new feed additives created on the basis of Gaprin and representing biomass of inactivated cell culture of non-pathogenic methane-oxidizing yeasts or bacteria on sturgeon fish productivity indicators was studied. The research was carried out in the Krasnodar Territory on sterlet fingerlings. The experiment lasted for 60 days. According to the scheme of the experiment, the 1st (control) group of fish received complete feeds without additives, i.e. containing 100.0% fish meal. In group 2 feeding, 50.0% fishmeal was replaced with 50.0% Gaprin. Group 3 diet contained 25.0% fishmeal and 75.0% Gaprin. In the feed for group 4, fish meal and Gaprin were in the ratio of 75/25%. In Group 5, fish meal was completely replaced by Gaprin, in this case the amount of additive was 10.5 kg. Sterlet fingerlings from Group 6 received feed with 10.0% Gaprin. The initial live weight in all groups was similar at 30 g. However, the inclusion of Gaprin in the diet by reducing the amount of fish meal contributed to an increase in the final live weight of sterlets in the experimental groups by 4.4–19.4% compared to the control. The exceptions were groups 5 and 6, which received 100.0 and 90.0% Gaprin instead of fishmeal. Final live weight in these groups was lower by 2.3 and 0.9%, respectively. Feed costs per 1 kg of live weight gain in the groups with partial or complete replacement of fish meal were lower relative to the 1st group (from 7.0 to 17.9%,).

Inclusion of Gaprin in complete feeds contributed to the increase in profit from 553.00 to 1785.00 rubles.

Розроблено й досліджено захисні властивості матеріалів для екранування неіонізуючих та іонізуючих електромагнітних полів і випромінювань, притаманних медичному обладнанню. Показано, що стаціонарні магнітні поля доцільно екранувати аморфними кобальтовими та кристалічними залізо-нікелевими сплавами малої товщини. Їх комбінація дозволяє уникати залежності коефіцієнта екранування від напруженості магнітного поля. Розроблено й досліджено захисні властивості композицій на основі латексу та сульфату барію для екранування рентгенівського випромінювання. Встановлено, що за товщини матеріалу 5 мм можливо отримати коефіцієнти екранування 1,4 – 5,8 у залежності від вмісту наповнювача. Розроблено й досліджено захисні властивості композицій на основі латексу й оксиду вольфраму для екранування гама-випромінювань. Визначено, що за товщини матеріалу 5 мм можливо отримати коефіцієнти екранування 1,1 – 3,8 у залежності від вмісту екрануючої субстанції. Вміст сульфату барію та оксиду вольфраму у 30 % за масою не впливає на однорідність матеріалів після висихання. Розтріскування поверхонь не виявлено. Перевагою отриманих композицій є можливість їх нанесення у рідкому стані. Випробування адгезивних властивостей сумішей при нанесенні на бетон та гіпсокартон свідчать про їх відповідність вимогам ДСТУ ISO 2409:2019. Це дозволяє наносити суміші на поверхні будь-якої форми у кілька шарів, що дає змогу регулювати коефіцієнти екранування у залежності від радіаційної та електромагнітної обстановки.
Social responsibility and firm value: The moderating role of firm size
Authors: Wijaya Liliana Inggrit , Sugiarto Lady Safitri , Sutejo Bertha Silvia
Published: May 2024

Social responsibility (SR) is a way for companies to fulfill their commitments to the public. If the companies have a positive public perception, investors will be more interested in purchasing stocks in the capital market, increasing the price. Therefore, social responsibility is expected to improve firm value, as measured by Tobin’s Q, and this study aims to prove the effect of SR on firm value moderated by its size and controlled by leverage and intensity of research and development. The research samples consist of 65 non-financial companies listed on the Indonesia Stock Exchange from 2019 to 2023 and are taken utilizing a purposive sampling technique. Acting as the data analysis method is the panel data regression model. The regression coefficient testing result displays that the interaction between SR and size positively influences company value. As the control variable, leverage negatively affects this value; however, research and development intensity has no influence. This research implies that SR is an effective strategy for improving the firm’s value as its size elevates by managing sustainable relationships with stakeholders amid rampant environmental issues.

Published: May 2024

Tüm sektörlerde enerji ihtiyacının ve birim fiyatlarının artmasından dolayı, yenilenebilir enerji kaynaklarına yönelim ve enerji verimliliği çalışmalarında artış olmaktadır. Enerjiyi verimli hale getirmenin bir yolu ısı transferi miktarını artırmaktır. Isı transferi miktarını artırmak için kullanılan yöntemlerden birisi de genişletilmiş (kanatlı) ısı transferi yüzeyleridir. Bu çalışmada, kompresör basma hattındaki kızgın buhar fazında olan soğutucu akışkan propanın (R290) sıcaklığının bir kısmından yararlanmak için basma hattına kurulmuş olan sıcak su kutusu içerisinde enerji verimliliğini sağlamak için tasarlanmış olan kanatlı borudan geçirilmektedir. Kanatlı borudan geçirilen propan sayesinde, kutudaki su ısınmaya başlayacaktır. Sistemde ısının gerekli olduğu durumlarda, enerji tüketmeden ısınan su (defrost, ürün ısıtma v.b.) kullanılmaktadır. Suyun, farklı sıcaklık farklarına göre kanat kalınlığının ve kanat aralarındaki mesafenin değişmesinin ısı transferine, kanat boyuna ve kanat sayısına etkisi incelenmiştir. Yapılan çalışma neticesinde; kanat kalınlığı ve kanatlar arasındaki mesafe arttıkça borudan yayılan ısı transferi miktarında azalma meydana gelmiştir. Kanat kalınlığı ve kanatlar arasındaki mesafe arttıkça boru boyunun uzadığı ve kanat sayısının azaldığı görülmüştür. Sıcaklık farkı 45oC olan su için hesaplamalar yapıldığında, 0.4 mm kanat kalınlığına sahip borunun boyu 16.98 cm olurken, kanat sayısı 58 adet olmaktadır. Kanatsız boru yerine kanatlı borunun kullanılması, boru boyunu kısaltmasının yanında aynı zamanda soğutucu şarj miktarını da azaltmaktadır.

Topicality. Determination of optimal load parameters in fitness, based on age-related physiological features and adaptive changes of the neuromuscular system, is one of the most debated issues among leading scientists in this field. The research purpose was to develop models of code combinations for strength training of different age groups, considering physiological processes of human body adaptation to a stressful physical stimulus in the conditions of strength fitness. Methods. A comparative analysis of the research results on the effectiveness of using the optimal combination between the parameters of an external physical stimulus and the physiological features of the human body adaptive reactions has been used over the research. The results. It was established that in the process of developing code combinations for different age groups` strength training, the nature of the physiological reactions of their neuromuscular system to a stressful stimulus depend on the features of the load regime and the structure of the exercise program. For adolescence, considering the peculiarities of the physiological process of adaptation, it is used of moderate-intensity activity in combination with a complex of isolation exercises that promotes the processes of intra-muscular and inter-muscular coordination. For youth, in the process of developing code combinations aimed at the development of the main types of strength, the entire range of load modes is actively used. Particular attention is paid to stimuli that contribute to increasing the number of active (FF) motor units. In adulthood, especially in the second period, the content of code combinations to increase strength capabilities changes significantly. In the vast majority, this applies to the parameters of the intensity of load modes, the use of which will selectively affect the hypertrophy of a certain type of muscle fibers within intermuscular coordination. For the elderly, in the process of developing code combinations for strength training, priority is given to the selective activity of agonists during moderate-intensity isolated exercises. Findings. Strength Simulator codes considering physiological processes of the neuromuscular system adaptation to a stressful physical stimulus, is one of the innovative mechanisms for improving the training program of different age groups in the conditions of strength fitness.

Published: May 2024

Topicality. Multiple studies have confirmed the significance of physical activity for the health of children and adolescents. However, in the majority of young individuals, their level of physical activity is insufficient. The aim of this article is to draw on the extensive experience of the Children’s Physical Activity Research Group (CPARG) team to develop a set of recommendations on promoting physical activity in children and youth. Methods of the research. The CPARG has applied public health research methods to the study of physical activity, that could be used to promote children’s physical activity at the population level. Results of the work and the key conclusions. A conceptual model for a set of recommendations regarding physical activity for children and youth has been developed, based on research and experience from CPARG, and divided into five categories. Two recommendations focus on persuading, prompting, and praising children and youth for engaging in physical activity at the individual and societal levels. Two recommendations emphasize the importance of providing places where children can engage in safe structured (programs), unstructured (play), and transportation physical activity, and one additional recommendation in the play, programs, participation & pleasure category stresses the importance of structuring these opportunities to facilitate fun, engagement, and enjoyment for children of all ages and abilities. Two recommendations address the need    for enacting and enforcing practices and policies to promote physical activity at the local to national levels. Finally, three recommendations build toward the goal of engaging in behaviors at the individual to societal levels to convey physical activity as the normative pattern, communicating that physical activity is what we do.

Relevance. Coaches and athletes across a variety of sports commonly perform abdominal exercises to promote core strength and endurance. However, the precise influence of abdominal strength and endurance on cycling performance remains elusive. Purpose. Determine whether abdominal fatigue affects anaerobic sprint and aerobic time- trial (TT) cycling performance. Methods. Twenty-three untrained young adults (age: 19,2 ± 1,0 years, height: 170,4 ± 7,5 cm, and weight: 74,5 ± 14,1 kg) participated in this study. Twelve of the participants completed two Wingate anaerobic power tests on a Monark 834 E ergometer set at 7,5 % of body mass and the remaining 11 participants completed two 3,2 km cycling TTs on an Expresso S3U virtual reality bike; tests were separated by 96 hours. All participants performed abdominal crunches to fatigue prior to the second test. Dependent t-tests were used to assess differences between the cycling trials for the two groups. Results. Abdominal muscle fatigue decreased mean anaerobic power (Pre: 486,75 vs. Post: 408,83 Watts (W, p < 0,001), increased the rate of fatigue (Pre: 42,01 vs. Post: 50,32 %, p = 0,004), and tended to decrease peak anaerobic power (Pre: 643,17 vs. Post: 607,27 W, p = 0,088). However, abdominal muscle fatigue did not affect TT mean power (Pre: 228,18 vs. Post: 220,09 W, p = 0,127) or TT performance (Pre: 382,7 vs. Post: 388,0 seconds, p = 0,222). Conclusion. Abdominal fatigue negatively affects anaerobic cycling performance in untrained young adults. Future studies should evaluate the impact of abdominal fatigue on cycling performance in trained cyclists.

Manajemen Pengetahuan (KM) memainkan peran penting dalam organisasi untuk tetap kompetitif dan inovatif dalam lanskap global yang berkembang pesat saat ini. Komunitas Praktik Virtual (VCoPs) telah muncul sebagai platform berharga untuk berbagi pengetahuan dan kolaborasi antar individu dengan kepentingan profesional yang sama. Tujuan dari penelitian ini adalah untuk menganalisis bagaimana pengetahuan berkembang dalam praktik komunitas virtual berdasarkan konsep SECI oleh Nonaka Takeuchi. Data yang digunakan berasal dari karya tulis ilmiah tentang implementasi KM pada VCoPs di beberapa bidang pada tahun 2017 hingga tahun 2023. Penelitian ini menggunakan Systematic Literature Review (SLR) berdasarkan metodologi PICOC. Tinjauan literatur sistematis ini mengamati dan mengidentifikasi implementasi KM melalui konsep konversi pengetahuannya. Hasilnya menunjukkan bahwa proses sosialisasi di ruang virtual sangat penting untuk mengatasi hambatan seperti jarak dan waktu, sehingga memungkinkan pertukaran pengetahuan terus menerus bahkan di luar jam kerja reguler. Proses eksternalisasi memfasilitasi pertukaran pengetahuan profesional yang relevan, termasuk cerita, konsep, video, atau gambar yang berkaitan dengan pengalaman kerja sehari-hari. Pada proses Kombinasi terdapat perbedaan antara VCoP satu dengan VCoP lainnya karena dipengaruhi oleh media online/virtual yang digunakan. Internalisasi sebagai keberlanjutan proses berbagi pengetahuan, khususnya terkait pendampingan, bervariasi antar VCoP. Kesimpulannya adalah meskipun KM telah menjadi bagian integral dari VcoP, terdapat tantangan seperti keterbatasan platform dan keberhasilan yang bervariasi dalam mengimplementasikan proses berbagi pengetahuan.

Students’ understanding of vector operations: With and without physics education technology simulation
Authors: Pranata Ogi Danika
Published: May 2024

This study aims to investigate the influence of technology integration (physics education technology simulation) in physics learning. A quantitative method with a quasi-experimental post-test-only design was applied to reveal the differences in students’ abilities to operate vectors between the group that learned and tested using simulation and the group that learned using graphics only. The test consisted of 16 questions on the addition and subtraction of two vectors divided into one and two dimensions. Student response data were analyzed using descriptive statistics and Kruskal-Wallis test. The analysis results show that the vector operation score for experimental group 1, which learned vector operations through graphic learning using simulation and tested with the same simulation (86.15), is higher than experimental group 2, which learned vector operations through graphic learning using simulation (76.59), and the control group, which learned vector operations through graphic learning without simulation assistance (71.81). All three groups have higher average scores for one-dimensional than two-dimensional vector operations. They also have higher average scores for vector addition compared to vector subtraction operations. Kruskal-Wallis test results indicate a significant difference in the average vector operation scores for the three groups (ρ=0.021). This suggests that integrating technology in the learning and testing processes leads to a significant difference. Moreover, the difference is significant for one-dimensional vector operations (ρ=0.004) and not significant for two-dimensional vector operations (ρ=0.107). These findings could support the implementation of similar approaches at the university and high school levels, especially for vector-related topics, in both learning and testing processes.

Published: May 2024

In mathematics, there are four basic operations that students must master from the elementary school level, namely addition, subtraction, multiplication, and division. However, some students experience difficulties or misunderstandings in interpreting multiplication as repeated addition. This research aims to improve the learning outcomes of second-grade students on multiplication material in elementary schools. This research used the teacher action research approach with 20 second-grade students at Kepuhan Sewon Public Elementary School as participants. Apart from that, this research used two data collection methods, namely providing mathematical worksheets and observations carried out by special observers. Data analysis was carried out by looking at the students’ average scores, reflecting through focus group discussions with observers, and filling in observation sheets by the teacher. Furthermore, the results of this research are presented in the form of teacher observation sheet scores and mathematical worksheets work results. The score results on the observation sheet show an increase in scores from learning in cycle 1 to cycle 2. In addition, the average score of students’ mathematical worksheets after intervention in the form of smart suitcase media and mathematical worksheets always increases with pre-cycle details (82), cycle I (93), and cycle II (94). Thus, the use of smart suitcase media assisted by mathematical worksheets has direct implications for improving the learning outcomes of second-grade students in the material of multiplication of integers.

Published: May 2024

The study examines the effect of exchange rate pass-through (ERPT) to inflation in Nigeria. The study period spans from 1990 to 2022 and data were sourced from Central Bank of Nigeria Statistical Bulletin and World Bank’s Development indicators (WDI). The study employed preliminary test of Augmented Dickey Fuller unit root test. Analytical technique of Autoregressive Distributed Lag (ARDL) model was used for the analysis. The dependent variable is Consumer price index proxied by inflation while the explanatory variables include monetary policy rate (MPR), nominal effective exchange rate (NEER), import price index (IMPI) and Global oil price (GOP). The result of unit root suggests mixed order of integration while the ARDL bound test demonstrate long run relationship among the variables under consideration. Findings indicate that exchange rate exhibit a positive and significant impact on consumer price while import price exerts a negative and significant influence on consumer price. Based on this outcome, the study suggests that monetary authority should exercise caution in using devaluation of the domestic currency to promote economic growth, as that would not only aggravate domestic inflation but also likely increase the ERPT. Given that exchange rate devaluation is unlikely to improve the country’s chances in the international market vis-à-vis its exports.
