Problem Bentuk dan Makna pada Kumpulan Puisi Dwibahasa Gurit Bandha Donya-Puisi Kekayaan Dunia
Authors: Shoim Anwar  
Published: February 2022

Tujuan peneltian ini adalah menginterpretasi, menganalisis, dan mendeskripsikan problem bentuk dan makna kumpulan puisi dwibahasa Gurit Bandha Donya-Puisi Kekayaan Dunia dalam kerangka pendekatan kualitatif. Kumpulan puisi ini memiliki makna beragam sesuai dengan kecenderungan tematik para penyairnya. Puisi yang berbahasa Jawa ditulis lebih awal, kemudian diterjemahkan oleh penyair ke bahasa Indonesia. Puisi berbahasa Jawa terasa lebih padat dibanding hasil terjemahannya. Ada kecenderungan dalam menerjemahkan penyair menambahkan kata-kata atau konsep tertentu sehingga bentuknya menjadi lebih panjang. Dalam kasus tertentu ada pula yang terjadi pengurangan konsep sehingga makna puisi menjadi berbeda.
Umumnya dalam penerjemahkan puisi penyair masih terikat pada penerjemahan kata perkata. Idiom-idiom dalam puisi belum dialihkan ke idiom bahasa lain yang maknanaya mirip. Kesenjangan idiom inilah yang menjadi permasalahan dalam penerjemahan puisi dari bahasa Jawa ke bahasa Indonesia.

Authors: Andre Yonathan Purba  , Mellisa Sim  , Putra Phimatra Jaya 
Published: February 2022

Background. Caries is a chronic infection of dental hard tissue. The development of caries is not limited to the tooth area, but caries can progress to the pulp chamber resulting in periapical lesions and abnormalities if not treated. Early detection of oral disease through radiographic examination is important, one of which is through periapical radiography.
Methods. This type of research is descriptive. The sample of this research is periapical radiography of cases of hard tissue disease at Prima Oral Dental Hospital period April – May 2021 as many as 78 photos. Sampling in this study was done by random sampling. Data were analyzed descriptively.
Results. Based on the interpretation of 78 photos periapical radiographs, it was found that the highest number of caries cases at Prima Oral Dental Hospital was superficial caries as much as 48.7%, followed by media caries as much as 43.6% and profunda caries only 7.7%. The mean and standard deviation of superficial caries depth was 3.51±1.348; medium caries 6.88±1.122 and profunda caries 10.00±1.549.
Conclusion. Superficial caries is the most caries case found on periapical radiographic examination at Prima Oral Dental Hospital, while profunda caries is the least caries case.

First of all, we, the editors, need to apologize for the delay in this year’s publication. The editorial team this year has been fighting against a number of issue and we want to express our sorrow to those all over the world who have lost those most beloved ones in this COVID-19 Pandemia. Let’s hope that this year will be better. In relation to this volume, we had a large amount of rejections since our interest is to improve the quality of the journal in just about two years including a much earlier publication date. Thus, this year we will be accepting papers until June 30. We understand this may limit the number of incoming papers, but we definitely will jump further into a higher quality journal that puts Encuentro Journal in the international place that it really deserves. Six articles published in this issue cover three main areas of interest: first, language learning and methodology are in focus; next, new approaches to improve English writing and oral skills. Finally, the last section concentrates on the attitudes and perception of teachers about the English lessons in foreign education systems and on translation studies.
Semantics of Declarativity in German Political Discourse Based on the Example of the Phrase “gute Politik”
Authors: Степанова М.А. 
Published: February 2022

В статье анализируется семантика декларативности в немецком политическом дискурсе на примере словосочетания “gute Politik" с позиций функциональной и когнитивной лингвистики, семантики и дискурсивной прагматики. Такие прилагательные, как “gut”, несмотря на статус семантических универсалий, не всегда однозначны, способны к модификации смысла в контексте и в свете конкретных речевых стратегий, а именно к расширению или утрате первоначального значения в зависимости от намерений говорящего и восприятия читателя/слушателя. Метод семантического поля позволяет не только описывать лексические значения, но и заглянуть глубже во внутреннюю структуру понятия. Пересекаясь с функционально-речевым полем, семантические признаки уступают место прототипическим признакам, которые определяют толкование и приоткрывают языковую картину мира.
The article analyses semantic aspects of declarativity in German political discourse as exemplified by an expression used by German chancellor Angela Merkel. The phrase “gute Politik” (engl. “good policy”) is analysed from the perspective of functional and cognitive linguistics, semantics and discourse pragmatics. Adjectives like “gut” (engl. “good”) are considered to be semantic universals, but they appear to be not always monosemantic, can modify meaning in some context through the lens of specific communicative strategies, can extend or lose their original meaning depending on the intentions of the speaker and the perception of the listener. The semantic field method can be used not only to describe lexical meaning. It crosses the functional field of speech, some semantic features give place to prototypic features, which determines interpretation, and reveal a certain linguistic world image.
Class I Methanol Masers Related to Shocks Induced by Bar Rotation in the Nearby Starburst Galaxy Maffei 2
Authors: Chen Xi , Yang Tian , Ellingsen Simon P. , McCarthy Tiege P. , Ren Zhi-Yuan 
Published: February 2022

Abstract
We report the detection of class I methanol maser at the 36.2 GHz transition toward the nearby starburst galaxy Maffei 2 with the Karl G. Jansky Very Large Array. Observations of the 36.2 GHz transition at two epochs separated by ∼4 yr show consistencies in both the spatial distribution and flux density of the methanol emission in this transition. Similar to the detections in other nearby starbursts the class I methanol masers sites are offset by a few hundred pc from the center of the galaxy and appear to be associated with the bar edges of Maffei 2. Narrow spectral features with line widths of a few km s−1 are detected, supporting the hypothesis that they are masing. Compared to other nearby galaxies with the detections in the 36.2 GHz methanol maser transition, the maser detected in Maffei 2 has about an order of magnitude higher isotropic luminosity, and thus represents the first confirmed detection of class I methanol megamasers. The spatial distribution of the 36.2 GHz maser spot clusters may trace the rotational gas flow of the galactic bar, providing direct evidence that the class I methanol maser is related to shocks induced by galactic bar rotation. A tentative detection in the 6.7 GHz class II methanol maser (at a 5σ level) is also reported. This is comparable in luminosity to some of the 6.7 GHz maser sources detected in Galactic star-forming regions. The 6.7 GHz methanol emission appears to be associated with star formation activity in a smaller volume, rather than related to the larger-scale galactic activities.
Estimations and Scaling Laws for Stellar Magnetic Fields
Authors: Wei Xing 
Published: February 2022

Abstract
In rapidly rotating turbulence (i.e., a Rossby number much less than unity), the standard mixing length theory for turbulent convection breaks down. However, the Coriolis force enters the force balance such that the magnetic field eventually depends on rotation. By simplifying the self-sustained magnetohydrodynamics dynamo equations of electrically conducting fluid motion, with the aid of the theory of isotropic nonrotating or anisotropic rotating turbulence driven by thermal convection, we make estimations and derive scaling laws for stellar magnetic fields with slow and fast rotation. Our scaling laws are in good agreement with the observations.
Stellar Loci. V. Photometric Metallicities of 27 Million FGK Stars Based on Gaia Early Data Release 3
Authors: Xu Shuai , Yuan Haibo , Niu Zexi , Yang Lin , Beers Timothy C. , Huang Yang 
Published: February 2022

Abstract
We combine LAMOST DR7 spectroscopic data and Gaia EDR3 photometric data to construct high-quality giant (0.7 < (BP − RP) < 1.4) and dwarf (0.5 < (BP − RP) < 1.5) samples in the high Galactic latitude region, with precise corrections for magnitude-dependent systematic errors in the Gaia photometry and careful reddening corrections using empirically determined color- and reddening-dependent coefficients. We use the two samples to build metallicity-dependent stellar loci of Gaia colors for giants and dwarfs, respectively. For a given (BP − RP) color, a 1 dex change in [Fe/H] results in about a 5 mmag change in (BP − G) color for solar-type stars. These relations are used to determine metallicity estimates from EDR3 colors. Despite the weak sensitivity, the exquisite data quality of these colors enables a typical precision of about δ [Fe/H] = 0.2 dex. Our method is valid for FGK stars with G ≤ 16, [Fe/H] ≥ −2.5, and E(B − V) ≤ 0.5. Stars with fainter G magnitudes, lower metallicities, or larger reddening suffer from higher metallicity uncertainties. With the enormous data volume of Gaia, we have measured metallicity estimates for about 27 million stars with 10 < G ≤ 16 across almost the entire sky, including over 6 million giants and 20 million dwarfs, which can be used for a number of studies. These include investigations of Galactic formation and evolution, the identification of candidate stars for subsequent high-resolution spectroscopic follow-up, the identification of wide binaries, and to obtain metallicity estimates of stars for asteroseismology and exoplanet research.
Partie III. Le renouveau de l’inflation ?
Authors: Le Bayon Sabine , Péléraux Hervé 
Published: February 2022

Après une année 2020 frappée de plein fouet par la pandémie de Covid-19, une baisse de la demande et une très faible inflation, l’année 2021 a vu la reprise accompagnée d’un fort rebond inflationniste. Le prix de l’énergie a flambé et de nombreuses matières premières ont vu leur prix augmenter également du fait de tensions importantes sur l’offre. L’inflation sous-jacente est pour le moment encore modérée dans la zone euro, mais elle inquiète au Royaume-Uni et surtout aux États-Unis où l’importance des plans de relance et les pénuries de main-d’œuvre accentuent les tensions. Le retournement à la baisse des prix de la plupart des matières premières depuis le printemps ou l’automne 2021 devrait contribuer négativement à l’inflation au cours de l’année 2022. Pour évaluer l’ampleur de cette contribution, nous avons estimé la sensibilité du déflateur de la consommation au prix des matières premières importées. Nous avons en particulier mesuré l’impact différencié d’un retour du prix du pétrole à 65 euros et de son maintien à 80 euros sur l’inflation en 2022.
« Basculement vers le virtuel »

Published: February 2022

La présente contribution examine, à partir de leurs déclarations rétrospectives, la manière dont 50 enseignants issus de 5 facultés/filières (Sciences appliquées, Psychologie, Sciences, Histoire, Sciences politiques) ont assuré, pour un cours défini, la « continuité de l’activité académique » à la suite du confinement COVID-19 de mars 2020. Les résultats suggèrent, d’une part, que le caractère exceptionnel des circonstances affrontées a pris le dessus sur la variété des réponses pédagogiques apportées et, d’autre part, que, dans le tumulte apparent lié à la pandémie, l’université est malgré tout parvenue à amortir les effets de cette perturbation de grande envergure. L’article confronte ces observations à l’avis des étudiants sur les mêmes 50 cours. Il en ressort là aussi une vision des bouleversements moins négative que ce que l’ampleur du « basculement vers l’enseignement virtuel » aurait pu laisser présager.
Exploratory study on didactic aspects used in scientific-technical (STEM) dissemination conferences for students of secondary education
Authors: Fuentes del Burgo Joaquin , Sánchez Tomás Juan Manuel , Ballesteros Garrido José Antonio , González Geraldo José Luis 
Published: February 2022

The connection between education and a country's economic and social development is unquestionable, and science and technology-related careers are of particular importance. Given the lack of vocations in these degrees, a number of mechanisms have been used to attract students, including science and technology conferences in secondary schools. Focusing on this type of lectures, this article aims to analyse the didactic aspects used by university lecturers who deliver this type of lectures. To this end, 16 teachers were interviewed using a structured interview. From the qualitative analysis of the interviews, we reached a series of results and conclusions, among which we would like to highlight the following: teachers see these lectures as a form of scientific dissemination which also helps to promote the degree courses they teach and serves as a support for attracting students; when choosing the content of the lecture, they mainly take into account the secondary school curriculum, including striking aspects and the results of their own research; the mediums used are mainly visual and supported by Do It Yourself techniques; the content is normally presented through presentations or practical laboratory exercises; finally, the documentation provided to students depends on the teacher giving the lecture, and there is no consensus on this point.

Published: February 2022

This study aims to assess the effectiveness of applying a socio-critical problem-oriented approach in environmental issues to develop students' critical thinking skills in chemistry learning. The qualitative methodology is conducted in which participants critically analyze articles relating to the effect of acids and bases in the environment. Participants are 36 grade 11 chemistry students from a high school in Jakarta, Indonesia. Data are collected by interviews, reflective student journals, teacher notes, observation sheets, worksheets, and critical thinking skills tests based on the five SCIT 1020 critical thinking indicators: problem identification, conceptual understanding, finding relationships between concepts, developing assumptions, and drawing conclusions. The results show an improvement in students’ critical thinking skills, motivation, and involvement in the learning process, providing support for using a socio-critical and problem-oriented approach to science learning. The socio-critical and problem-oriented can be used as an alternative approach to chemistry learning or other subjects that is applicable and contextual in daily life and the environment and can be used to increase student activity in the classroom and critical thinking skills on learning process.
