Authors: Siti Maharani Malayu  , Yuddi Adrian Muliadi
Published: February 2022

This research is focused on case studies involving six speakers, native and non-native, in pronouncing Japanese verbs. This research includes an acoustic phonetic study with the help of the PRAAT application which is used to calculate the duration, intensity, and frequency of speech. The subject of discussion in this study were eight Japanese verbs. The research is focused on looking at the similarities and differences of teachers from Indonesia and Malaysia in terms of duration, intensity, and frequency compared with native speech. The research method for obtaining a comparison of the duration, intensity, and frequency of speakers is descriptive-analysis by presenting data in the form of numeric tables and graphs. This study involved two native speakers and six non-native speakers, namely four speakers from Indonesia and two from Malaysia. The data collection method uses PRAAT with audio files as the main data source. The results of this study indicate that the eight target verbs [au], [iku], [isogu], [demasu], [dekakeru], [orinai], [hairimasu], and [norikaemasu] occur variations in terms of duration, intensity, and frequencies spoken by non-natively. For non-native women, the tendency is not too far different from native, both non-native from Indonesia and from Malaysia. However, there was a significant variation for non-native males. Non-native speakers from Malaysia tended to be the same for minimum measures of intensity and frequency, while those from Indonesia tended to be the same for maximum measures of intensity and frequency. For the duration of non-native speakers from Malaysia, the percentage is closer to the native duration. Meanwhile, there were variations in intensity and frequency between non-natives from Indonesia and Malaysia.

Authors: Sisila Fitriany Damanik  , Tiarnita Maria Sarjani Siregar
Published: February 2022

The purpose of this research is to demonstrate how structural characteristics of conversational humour are related to the functions served by hilarious utterances and acts. Linguistically speaking, examining humour can provide us with a wealth of information about the society in which we live. Regrettably, not all linguists believe that researching humour is a wise approach. Additionally, this study will examine the suburban community's debate in one of the most popular YouTube videos, Kontrakan Rempong by Warintil official. Pamer provided the funny data (episode 69). The approach employed in this study is Fairclough's CDA model, which evaluates the dimensions of text, specifically the GTVH theory, interpretation, and explanation (social practice). As a result, it is discovered that residents' noticeable behaviors, in particular, become a regular topic of debate among the community's housewives. The theme is primarily concerned with how members of a particular family behave in the community and how women as homemakers identify as community members. The targeted behaviors include being chatty, materialistic, impolite and pompous, having an unconventional view of the world, and gossipmongers who spread tales about another person's debt.

Authors: Pourbaix Maridelma de , Maldonado da Silva Renata
Published: February 2022

O objetivo deste trabalho é o de problematizar o processo de construção da profissionalização do professor de Matemática no Brasil. As primeiras inciativas voltadas para o ensino da Matemática ocorreram por meio dos engenheiros e dos militares, a partir principalmente do período Imperial, com a criação das academias militares. Somente, nas primeiras décadas do século XX, em função das transformações no ensino da Matemática, somadas às mudanças acerca do papel da escola na sociedade e, diante de uma nova atuação do papel do Estado em relação à educação, a exigência de um profissional que detivesse um conjunto de conhecimentos específicos para o ensino da Matemática tornou-se essencial. Utilizou-se neste artigo o método dedutivo, a partir de uma abordagem descritiva e documental acerca da constituição do campo profissional do docente de Matemática no Brasil. A organização dos sistemas de ensino no país, na década de 1930, a partir da Reforma Francisco Campos, e a criação dos cursos de licenciaturas, impuseram novos rumos à formação dos professores de Matemática, apesar das resistências e contradições ainda presentes entre os diferentes sujeitos que atuavam neste campo do conhecimento naquele contexto.

Authors: Taiwo Osijo Adedeji , Olugbemileke Otusanya Marian , Gboyega Afolabi Clement , Alaba Olowokere Florence
Published: February 2022

Yam (Dioscorea spp) production is beset in the field and in storage by major fungal pathogens, namely Colletotrichum gloeosporioides that causes anthracnose in the field, and Rhizopus stolonifer that causes tuber rot in storage. Alternative control measures are imperative as conventional control of these pathogens is either ineffective or detrimental. This study investigated the effects of calcium fertilizer on the incidence and severity of anthracnose and Rhizopus rot of yam. Calcium nitrate fertilizer was applied to soils naturally infected with C. gloeosporioides, at the rates of 0, 3, and 4kg ha-1. D. rotundata variety Efuru was planted. The treatments were arranged in a randomized complete block design with three replicates. Anthracnose disease rating relied on natural endemic infection in the field, while inoculation of harvested yam tubers was carried out using R. stolonifer. There was no significant effect of calcium amendment of the soil on anthracnose severity in D. rotundata or on the agronomic parameters. D. rotundata tubers treated with 3 and 4kg ha-1 calcium soil amendments had reduced infection by R. stolonifer in storage compared to the control treatments. The study concluded that calcium applied to the soil had reduced storage losses by R. stolonifer in D. rotundata but had no influence on anthracnose severity in the field. Therefore, 3kg ha-1 of calcium nitrate applied to the soil can be used to improve D. rotundata tuber resistance to R. stolonifer, and is recommended for high-quality tuber storage.

Authors: Cabelin Gladys , Ceniza Maria Juliet
Published: February 2022

The Coconut Leaf Beetle, scientifically known as Brontispa longissima (Gestro), is an introduced species that is becoming an alarming pest of coconuts in the Philippines. The infestation caused by this pest is damaging to all stages of coconut growth. This study was conducted to assess the degree of damage and infestation caused by Brontispa longissima on the seedlings of 10 selected tall and dwarf coconut varieties in the National Coconut Research Center at Visayas State University, Leyte, Philippines. Among the selected varieties, seedlings of Baybay Tall (green and brown) and Albuera Dwarf varieties succumbed to more damage by B. longissima beetles compared with the other varieties observed with 41-80% of the first openned leaf area damaged. Seedlings of Malayan Yellow Dwarf and Malayan Red Dwarf varieties had the least damage with 0-20% of the first openned leaf area damaged. The high damage ratings of Baybay Tall and Albuera Dwarf were expected because these varieties had high infestation rates and harbored the most numbers of B. longissima adults, eggs, and larval stages, which indicated the preference of B. longissima for these varieties. The developmental period of B. longissima in Baybay Tall and Albuera Dwarf of 44 days and 45 days on the average, respectively, was shorter than in other varieties, indicating that these are suitable and preferred hosts. Baybay Tall seemed to be the most preferred variety. The beetles had least preference for Malayan Yellow Dwarf and Malayan Red Dwarf varieties.
Isolation, characterization and antibacterial activity of actinomycetes from soils of the Langun-Gobingob Cave Complex in Calbiga, Samar
Authors: Damayo Jeffrae Isaac Albert , Fuentes Rolly
Published: February 2022

The discovery of rare Actinomycetes from unexplored areas has proven to be a promising source of new antimicrobials. The Langun-Gobingob cave complex in Calbiga, Samar, Philippines is the second largest cave complex in Asia, yet this is the first reported search for actinomycetes conducted in the area. The main objective of this study was to assess the antibacterial activities of culturable actinomycetes from soil samples from the Langun-Gobingob cave complex. Five actinomycete colonies were isolated in pure culture from soil samples using Starch-Casein Agar medium. The isolates were identified by their morphological characteristics and they were characterized by 16S rRNA sequencing. The sequences were matched to sequences uploaded to the NCBI Basic Local Alignment Search Tool (BLAST). Four of the isolates belonged to the Genus Streptomyces and one belonged to the Genus Nocardia. The antibacterial potential of the isolates was tested against gram-positive and gram-negative test bacteria. One Streptomyces isolate exhibited antibacterial activity against the two gram-positive test bacteria. The limited cave area sampled in this study leaves the cave complex mostly unexplored in the search for antibacterial secondary metabolites.
Influence of plant growth regulators and UV light exposure on the formation and phenolic content of stevia rebaudiana bertoni callus: a preliminary study
Authors: Pacaldo Florina , Arradaza Catherine
Published: February 2022

This study was conducted to evaluate the effect of different combinations and levels of plant growth regulators, 2,4-dichlorophenoxy acetic acid (2,4-D) and 6-benzylaminopurine (BAP), on callus induction of Stevia rebaudiana Bertoni leaf and internode explants, and the total phenolic content of Stevia callus as influenced by the length of exposure to ultraviolet (UV) light radiation. Early callus initiation was recorded in leaf explants inoculated in Murashige and Skoog (MS) medium supplemented with 2,4-D and BAP. After a week of incubation, leaf explants showed callus formation while in internode explants, callus formation was observed 2 weeks after inoculation. The culture medium supplemented with 1.5mg L-1 2,4-D + 2.0mg L-1 BAP (T4) was the best treatment for leaf explants with 95% callus formation and the addition of 1.0mg L-1 2,4-D + 4.0mg L-1 BAP (T3) was the best treatment for internode explant with 90% callus formation. After 4 weeks of incubation, the leaf and internode calli were observed as compact, non-embryogenic, and yellowish green in all treatments except those inoculated in MS medium alone (control). Stevia leaf callus was subjected to UV radiation after 4 weeks at varying time of exposure. The exposed calli turned brown signifying a possible increasing production of secondary metabolites. Furthermore, combination of 1.5mg L-1 2,4-D + 2.0mg L-1 BAP (T4) and 3h of UV light exposure yielded the highest phenolic content of 87.71mg GAE per g callus. The results further revealed that both medium composition and time of exposure affect the production of phenolic content of Stevia leaf callus.
GAMIFICATION IN COMPUTER SCIENCE COURSES: A LITERATURE REVIEW
Authors: Özdamli Fezile , Yazdeen Dlgash Faran
Published: February 2022

The complicated, boring problems in computer science learning make them lack motivation during the COVID-19 pandemic. The further exciting and appealing educational setting is the more significant learners' participation in the learning challenge. A traditional setting was not appealing too much, creating a dull environment that has no learning motivation. Gamification is often used as an instrument for motivating learners and increasing their commitment. A study analyzes several previous research types in this field to assess gamification's effect on higher education students in a computer science course. The results conclude that gamification enhances the interest and encouragement of the learners. Also, it improves computer science curriculum training and knowledge of a complicated topic, providing learners with optional barriers. While they are beneficial, pedagogical games may have drawbacks that impact either emotionally and physically learners. The most popular gamification elements used during computer science classes were badges, leaderboards, score, level, and feedback. They were the most commonly known feature of the game in learning computer science. Implementing components of gamification in education is a resource that can motivate learners in computer science education. Gamification can give positive outcomes for student's achievement and the teaching and learning process framework, which teachers increasingly accept. Further research is required to determine if this transforms into an effect on finished performance and governs particular group impacts. Students' academic achievement and results in the computer science curriculum must develop a broader amount of knowledge on the utility through gamification.

Published: February 2022

Through education, societies raise the awareness within future generations and shape them as they wish. Due to the importance of educational institutions, organizational commitment of employees in educational institutions is also important. Detection and comparison of organizational commitment before and during the pandemic will be an important source of data in this challenging period.

The aim of the research is to evaluate the situation of providing and developing organizational commitment of administrators and teachers in educational organizations before and during the pandemic in public primary schools in the 2020-2021 education period. In line with the research objectives, open-ended questions were asked to 20 teachers and 20 administrators, and the data of the research were obtained.

After the analysis of the research data, the following conclusions were reached: When the participants were mentioned about organizational commitment, it was concluded that the teachers and administrators thought of the work commitment (loyalty).

The results show that before the pandemic, administrators organized dining events according to the teachers’ and the administrators' views in order to ensure organisational commitment. The teachers defend that an equal and fair environment should be reached when developing organisational commitment while the administrators think the environment should be motivating. In order to provide, develop and maintain the organisational commitment, teachers believe that it is important to be equal and fair and the administrators believe that constructive criticism should be present.

It has been concluded that during the pandemic, to ensure organisational commitment, the administrators arrange online meetings according to the teachers’ and the administrators’ opinion.  While teachers mention the need to be in close dialogue (continuous dialogue) to develop organizational commitment, administrators say that there should be an effective communication environment. Also, according to the teachers, in providing, developing and maintaining organizational commitment, it is necessary to be motivating, it is achieved through good (effective) communication according to the views of the administrators.

Towards the Definition of Logical Competence
Authors: Schumann Andrew
Published: February 2022

According to logical psychologism that was popular in the nineteenth century, logic was regarded as a natural ability of human psychology. Consequently, logical competence as a realization of logic knowledge was treated as one of the innate features of human thinking. Nevertheless, within cognitive science, it was experimentally proved that our thinking is not free from cognitive biases, and to the same extent, our reasoning is not free from logical fallacies. Hence, we are forced to consciously clear the thinking of possible distortions to follow logical norms and to realize logical competence thereby. In the paper, it is shown that some cognitive biases are observed even at the level of cellular reactions to the environment and then at the level of animal behavior. Therefore not logic, but cognitive biases are a natural (biological) mechanism of human thinking. So, the problem of defining logical competence arises. In this paper, there are some arguments that logical competence has once appeared as an especial social practice and it has then been developed for a long time before the first treatises on logic.

Este trabajo tiene como objetivo determinar la eficiencia de los principales países productores de petróleo en el área de comercialización durante el periodo 2010-2017, a partir de la metodología del análisis de la envolvente de datos (DEA por sus siglas en inglés). Se utiliza un modelo con rendimientos variables a escala y orientación output, y se instrumenta el estadístico bootstrap para darle robustez al modelo. En los resultados se observa que en general, ningún país fue eficiente. Sin embargo, el Reino Unido tuvo los niveles más altos de eficiencia, en el lado opuesto, se encuentra Brasil con valores muy reducidos en este indicador. Se concluye que en general, en materia de eficiencia, no se tuvo una adecuada utilización de los recursos del sector petrolero en el área de comercialización a nivel mundial. Se recomienda establecer estrategias en el sector para evitar la vulnerabilidad económica. El impacto que se tiene con estos estudios es que, a través de los resultados obtenidos, se pueden realizar propuestas para mejorar los niveles de eficiencia de la industria petrolera.
YTHDF3 modulates hematopoietic stem cells by recognizing RNA m6A modification on Ccnd1

Published: February 2022

Hematopoietic stem cells (HSC) give rise to the cells of the blood system over the whole lifespan. N6-methyladenosine (m6A), the most prevalent RNA modification, modulates gene expression via the processes of “writing” and “reading”. Recent studies showed that m6A “writer” genes (Mettl3 and Mettl14) play an essential role in HSC. However, which reader deciphers the m6A modification to modulate HSC remains unknown. In this study, we observed that dysfunction of Ythdf3 and Ccnd1 severely impaired the reconstitution capacity of HSC, which phenocopies Mettl3-deficient HSC. Dysfunction of Ythdf3 and Mettl3 results in a translational defect of Ccnd1. Ythdf3 and Mettl3 regulate HSC by transmitting m6A RNA methylation on the 5’ untranslated region of Ccnd1. Enforced Ccnd1 expression completely rescued the defect of Ythdf3-/- HSC and partially rescued Mettl3-compromised HSC. Taken together, this study identified, for the first time, that Ccnd1 is the target of METTL3 and YTHDF3 to transmit the m6A RNA methylation signal and thereby regulate the reconstitution capacity of HSC.

Орієнтовно сполука належить до V класу токсичності – практично нетоксичні речовини.
Why do «empty» liposomes have their own biological activity?
Authors: Soloviev A. І.
Published: February 2022

It is well known, that liposomes are successfully used, first of all, in pharmacology and pharmacotherapy, for drug delivery, but their own biological activity cannot be excluded. The data obtained clearly demonstrate, that even empty (i. e., containing no active substances in their internal cavity or membrane) phosphatidylcholine liposomes (PCL), i. e. liposomes per se, possess an amazing ability to normalize the contractile activity of blood vessels impaired under hypoxia, restore endothelial function at arterial hypertension and diabetes, and even to renovate endothelium-dependent relaxant vascular function damaged after exposure to ionized γ-radiation. It was shown also that liposomes per se effectively restored Maxi-K channels activity damaged following genotoxic oxidative stress induced by γ-radiation. Thus, empty phosphatidylcholine liposomes have a pronounced intrinsic biological activity regarding vascular tissues. This is a really surprising discovery and these effects may be due to their ability to influence the phospholipid environment of ion channels and, thereby, to modulate ion channel functional activity.

Наявність дефіциту принаймні однієї незамінної амінокислоти робить раціон харчування людини неповноцінним, що може стати причиною розвитку ряду патологічних станів організму.Виходячи з цього, одним з актуальних питань сучасної фармації є пошук нових джерел походження рослинних білків та амінокислот, які можна буде застосувати для розширення асортименту вітчизняних біологічно активних добавок і лікарських засобів.Мета дослідження – вивчити якісний склад і кількісний вміст вільних і зв’язаних амінокислот у траві та коренях самосилу гайового (Teucrium сhamaedrys L.) і самосилу гірського (Teucrium montanum L.).Для визначення суми амінокислот використовували методику, запропоновану Штейном і Муром у сучасній модифікації, зі застосуванням автоматичного аналізатора амінокислот моделі ААА Т – 339 (Чехія).Попередньо підготовану наважку сировини розчиняли в цитратному буферному розчині та піддавали аналізу. Розподіл компонентів здійснювали на аналітичній колонці, яку заповнювали катіонітом LG ANВ. Для реєстрації амінокислот використовували метод детекцiї нiнгiдрином.Отримані дані свідчать про наявність у всіх зразках досліджуваної рослинної сировини 18 амінокислот, з яких 7 є незамінними. Найбільша кількість амінокислот міститься у траві Teucrium сhamaedrys L. – 7,161 мг/100 мг. Вміст амінокислот у коренях самосилу гайового та траві самосилу гірського практично однаковий 3,853 мг/100 мг та 3,703 мг/100 мг відповідно. Найменша кількість амінокислот міститься у коренях самосилу гірського – 2,391 мг/100 мг. У найбільшій кількості в рослинній сировині присутні аспарагінова та глутамінова кислоти. Серед переважаючих амінокислот варто відзначити лейцин, гліцин, лізин та аланін, концентрація яких у досліджуваних об’єктах складає 5–10 % від загального вмісту амінокислот.Результати проведених досліджень розширюють існуючі відомості про амінокислотний склад трави та коренів Teucrium сhamaedrys L. і Teucrium montanum L.

A field experiment was conducted at the Agronomy field, Sher-e-Bangla Agricultural University, Dhaka to evaluate the effect of water stress at reproductive stage on growth, grain development and yield of Boro rice. The experiment consisted of two factors: Factor A: Water stress viz. no water stress (W1) and water stress (W2) and Factor B: Variety viz. BRRI dhan28 (V1), BRRI dhan29 (V2), BRRI dhan50 (V3), Binadhan-10 (V4), BRRI hybriddhan3 (V5), Aloron (V6). In no water stress, irrigation water was maintained strictly from transplanting time to harvesting time while in water stress condition; supply of irrigation was stopped just after flowering upto harvest. Results showed that growth, grain development and yield of Boro rice were significantly affected by water stressed condition. All the tested varieties performed better under no water stress condition compared to water stress condition. About 7% panicle weight was decreased due to water stress condition at reproductive stage. Grain development of BRRI dhan29 was least affected by water stress while the most affected variety was Binadhan-10. Water deficit at reproductive stage reduced about 15-22% grain yield of tested varieties. Aloron was the least affected variety due to water stress while BRRI dhan50 was the most affected variety. The variety Aloron provided equal yield (7.31 t ha-1) under stress condition as given by BRRI dhan29 under no water stress condition. So, Aloron may be a better option to cultivate in the region where irrigation water is scarce or costly.

Published: February 2022

The production area of chickpea in Bangladesh is decreasing day by day due to the competition with higher yielding crop which is/or profitable than chickpea. As such, the experiment was undertaken at Regional Agricultural Research Station, Jashore during 2019-2020 and 2020-2021 to study the effect of most suitable method of de-topping (nipping) in chickpea (var. BARI Chola-10) for its growth and yield improvement. Treatments were imposed in a split-plot design where in main plot : time of nipping : 30 days after emergence (DAE) , 40 DAE E3- 50 DAE and in sub-plot: different heights of nipping practices: Control, Nipping 5 cm from growing tip, Nipping 8 cm from growing tip and Nipping 10 cm from growing tip. In interaction treatment, the highest days to flower (68), days to mature (112), vegetable yield (703 kg ha-1) was observed when chickpea plants were de-topped after 50 DAE at 10 cm from growing tip. The highest plant height (46 cm) was observed when de-topping at 40 DAE was done at 10 cm from growing tip. Seed yield (1419.95 kg ha-1) and Marginal Benefit Cost Ratio (MBCR) (13.1) was recorded maximum when chickpea plants de-topped 50 DAE at 5 cm from growing tip. De-topping practices in chickpea (var. BARI Chola-10) after 50 DAE at 5 cm from growing tip could maximize the productivity of chickpea.
