The Impact of Internet Use on the Happiness of Chinese Civil Servants: A Mediation Analysis Based on Self-Rated Health
Authors: Sui Mengyuan , Ding Haifeng , Xu Bo , Zhou Mingxing
Published: October 2022

With the rapid socioeconomic development of China, studies related to Internet use and civil servants’ happiness have become a research hotspot in Chinese academia. This study empirically analysed the impact of Internet use on the happiness of Chinese civil servants using a sample of 3793 civil servants in Hunan Province, China. It showed that Internet use significantly enhanced the subjective well-being of Chinese civil servants. Furthermore, heterogeneity analysis revealed significant heterogeneity in the effect of the Internet on civil servants’ happiness, which varied across civil service groups with different education and gender. Moreover, the effect of Internet use on the happiness of the male and better educated civil servant groups was more pronounced than in the female and less educated civil servant groups. Additionally, mediation analysis revealed that Internet use and the happiness of civil servants were not linear, with health having a significant mediating effect. This indicates that Internet use helps civil servants maintain good health, and thereby enhances the happiness of civil servants. In addition, we also use a propensity score matching model (PSM) to address the endogeneity problem due to sample selectivity bias. The results show that the estimates are more robust after eliminating sample selectivity bias. The effect of Internet use on civil servants’ subjective well-being would be underestimated if the sample selectivity bias is not removed.

Published: October 2022

In recent years, the incidence of type I hypersensitivity including hay fever has been increasing year by year in Japan. Our previous study using mice showed that only oral, but not intraperitoneal, administration of fucoidan extracted from seaweed (Saccharina japonica) suppressed type I hypersensitivity by secretion of galectin-9, which has a high affinity for IgE in the blood. However, the amount of seaweed required to achieve this activity is quite high (12 g dry weight per person per day). Therefore, the purpose of this study was to search for food ingredients in vegetables that enhance type I hypersensitivity suppression effect when consumed together with fucoidan. As a result, the enhanced effect was observed in extracts from Welsh onions and onions among vegetables. When we compared the polyphenols in the vegetables that showed activity with those that did not, flavonols such as quercetin and kaempferol were found as candidates. When quercetin or kaempferol (100 μg each) were orally administered at the same time, even at amounts where fucoidan alone showed no anti-allergic activity, anti-allergic effects were observed. More interestingly, when both flavonols were combined and administered simultaneously at half the amount of each of the above flavonols (50 μg), while the fucoidan amount remained the same, a similar effect was observed as when each flavonol (100 μg) was administered alone. The simultaneous intake of fucoidan and vegetables containing high contents of quercetin or kaempferol may reduce fucoidan intake while maintaining the allergy suppression effect, suggesting the importance of food combination.

Published: October 2022

The K-homology (KH) domains are small, structurally conserved domains found in proteins of different origins characterized by a central conserved βααβ “core” and a GxxG motif in the loop between the two helices of the KH core. In the eukaryotic KHI type, additional αβ elements decorate the “core” at the C-terminus. Proteins containing KH domains perform different functions and several diseases have been associated with mutations in these domains, including those in the fragile X mental retardation protein (FMRP). FMRP is an RNA-binding protein crucial for the control of RNA metabolism whose lack or mutations lead to fragile X syndrome (FXS). Among missense mutations, the R138Q substitution is in the KH0 degenerated domain lacking the classical GxxG motif. By combining equilibrium and kinetic experiments, we present a characterization of the folding mechanism of the KH0 domain from the FMRP wild-type and of the R138Q variant showing that in both cases the folding mechanism implies the accumulation of an on-pathway transient intermediate. Moreover, by exploiting a battery of biophysical techniques, we show that the KH0 domain has the propensity to form amyloid-like aggregates in mild conditions in vitro and that the R138Q mutation leads to a general destabilization of the protein and to an increased fibrillogenesis propensity.

Authors: Zhu Yu , Wang Jian , Meng Fanqiang , Liu Tongtao
Published: October 2022

The advancement of autonomous driving technology has had a significant impact on both transportation networks and people’s lives. Connected and automated vehicles as well as the surrounding driving environment are increasingly exchanging information. The traditional open road test or closed field test, which has large costs, lengthy durations, and few diverse test scenarios, cannot satisfy the autonomous driving system’s need for reliable and safe testing. Functional testing is the emphasis of the test since features such as frontal collision and traffic sign warning influence driving safety. As a result, simulation testing will undoubtedly emerge as a new technique for unmanned vehicle testing. A crucial aspect of simulation testing is the creation of test scenarios. With an emphasis on the map generating method and the dynamic scenario production method in the test scenarios, this article explains many scenarios and scenario construction techniques utilized in the process of self-driving car testing. A thorough analysis of the state of relevant research is conducted, and approaches for creating common scenarios as well as brand-new methods based on machine learning are emphasized.

Authors: Spinczyk Dominik , Fabian Sylwester , Król Krzysztof
Published: October 2022

Objective: Respiratory movements are a significant factor that may hinder the use of image navigation systems during minimally invasive procedures used to destroy focal lesions in the liver. This article aims to present a method of estimating the displacement of the target point due to respiratory movements during the procedure, working in real time. Method: The real-time method using skin markers and non-rigid registration algorithms has been implemented and tested for various classes of transformation. The method was validated using clinical data from 21 patients diagnosed with liver tumors. For each patient, each marker was treated as a target and the remaining markers as target position predictors, resulting in 162 configurations and 1095 respiratory cycles analyzed. In addition, the possibility of estimating the respiratory phase signal directly from intraoperative US images and the possibility of synchronization with the 4D CT respiratory sequence are also presented, based on ten patients. Results: The median value of the target registration error (TRE) was 3.47 for the non-rigid registration method using the combination of rigid transformation and elastic body spline curves, and an adaptation of the assessing quality using image registration circuits (AQUIRC) method. The average maximum distance was 3.4 (minimum: 1.6, maximum 6.8) mm. Conclusions: The proposed method obtained promising real-time TRE values. It also allowed for the estimation of the TRE at a given geometric margin level to determine the estimated target position. Directions for further quantitative research and the practical possibility of combining both methods are also presented.
Temporal Prediction Model-Based Fast Inter CU Partition for Versatile Video Coding
Authors: Li Yue , Luo Fei , Zhu Yapei
Published: October 2022

Versatile video coding (VVC) adopts an advanced quad-tree plus multi-type tree (QTMT) coding structure to obtain higher compression efficiency, but it comes at the cost of a considerable increase in coding complexity. To effectively reduce the coding complexity of the QTMT-based coding unit (CU) partition, we propose a fast inter CU partition method based on a temporal prediction model, which includes early termination QTMT partition and early skipping multi-type tree (MT) partition. Firstly, according to the position of the current CU, we extract the optimal CU partition information of the position corresponding to the previously coded frames. We then establish a temporal prediction model based on temporal CU partition information to predict the current CU partition. Finally, to reduce the cumulative of errors of the temporal prediction model, we further extract the motion vector difference (MVD) of the CU to determine whether the QTMT partition can be terminated early. The experimental results show that the proposed method can reduce the inter coding complexity of VVC by 23.19% on average, while the Bjontegaard delta bit rate (BDBR) is only increased by 0.97% on average under the Random Access (RA) configuration.

Published: October 2022

Along with the rapid development of autonomous driving technology, autonomous vehicles are showing a trend of practicality and popularity. Autonomous vehicles perceive environmental information through sensors to provide a basis for the decision making of vehicles. Based on this, this paper investigates the lane-changing decision-making behavior of autonomous vehicles. First, the similarity between autonomous vehicles and moving molecules is sought based on a system-similarity analysis. The microscopic lane-changing behavior of vehicles is analyzed by the molecular-dynamics theory. Based on the objective quantification of the lane-changing intention, the interaction potential is further introduced to establish the molecular-dynamics lane-changing model. Second, the relationship between the lane-changing initial time and lane-changing completed time, and the dynamic influencing factors of the lane changing, were systematically analyzed to explore the influence of the microscopic lane-changing behavior on the macroscopic traffic flow. Finally, the SL2015 lane-changing model was compared with the molecular-dynamics lane-changing model using the SUMO platform. SUMO is an open-source and multimodal traffic experimental platform that can realize and evaluate traffic research. The results show that the speed fluctuation of autonomous vehicles under the molecular-dynamics lane-changing model was reduced by 15.45%, and the number of passed vehicles was increased by 5.93%, on average, which means that it has better safety, stability, and efficiency. The molecular-dynamics lane-changing model of autonomous vehicles takes into account the dynamic factors in the traffic scene, and it reasonably shows the characteristics of the lane-changing behavior for autonomous vehicles.

Authors: Yin Ziwei , Li Kun , Bi Hongjun
Published: October 2022

Aiming at the problems of single detection target of existing distributed denial of service (DDoS) attacks, incomplete detection datasets and privacy caused by shared datasets, we propose a trusted multi-domain DDoS detection method based on federated learning. Firstly, we divide the types of DDoS attacks into different sub-attacks, design the federated learning dataset for DDoS detection in each domain, and use them to realize a more comprehensive detection method of DDoS attacks on the premise of protecting the data privacy of each domain. Secondly, in order to improve the robustness of federated learning and alleviate poisoning attack, we propose a reputation evaluation method based on blockchain, which estimates interaction reputation, data reputation and resource reputation of each participant comprehensively, so as to obtain the trusted federated learning participants and identify the malicious participants. In addition, we also propose a combination scheme of multi-domain detection and distributed knowledge base and design a feature graph of malicious behavior based on a knowledge graph to realize the memory of multi-domain feature knowledge. The experimental results show that the accuracy of most categories of the multi-domain DDoS detection method can reach more than 95% with the protection of datasets, and the reputation evaluation method proposed in this paper has a higher ability to identify malicious participants against the data poisoning attack when the threshold is set to 0.6.
lntraspecific Dietary Breadth, Overlap Indices and Feeding Strategies of Puntius gonionotus Bleeker and Oreochromis spp. in a shallow pond from Bangladesh
Authors: HAROON A. K. YOUSUF
Published: October 2022

Intraspecific virtual dietary breadth, degree of diet similarity, dietary overlap and feeding strategies of the silver barb Puntius gonionotus and the tilapia Oreochromis spp. were estimated in a pond from Bangladesh and compared using various niche indices. Appropri­ateness, ease of interpretation and explanation of different indices were evaluated. Dietary breadths were relatively higher in small sizes of P. gonionotus than large ones, though neither size class could be considered as a generalist feeder. There was a significant di­etary overlap between large and small barbs. Niche breadths were similar for both sizes of Oreochromis spp., a little higher for the small sizes, although as with the barbs, neither size class could be considered as a generalistic feeder. Dietary overlap of large tilapia on small ones was much greater but significant in both ways. Czekanowskis' Proportional Similarity (PS) index reveals a much broader aspect of the ecological determinants of niche breadth as it incorporates resource availability and resource use and has got the ease of biological interpretation. Similarly, Levins' dietary overlap indices reveal clearly both the significance, strength and direction of dietary overlap between competitors. According to the PS index, both species are opportunistic feeders, although tilapias are relatively more generalist than the silver barbs. Evidence of significant dietary overlap between the large and small sizes of both species reflects strong competition and indicates caution for mixed-­size stocking of tilapia in pond polyculture. Feeding pattern of silver barb reflected a mixed strategy with a combination of both high between- and within-phenotype contributions to the niche width, but with the between-phenotype contribution as the largest. While tila­pias reflected high within-phenotype contributions to the niche width, a generalized feed­ing strategy showed a trend of specialization of a population for periphytic food.
The Role of Aeromonas hydrophila Protease in the Utilization of Fish Serum Iron in vitro
Authors: TANG F.
Published: October 2022

Some authors argue that pathogenic bacteria could compete against serum transferrin for iron by their siderophore. However, Aeromonas hydrophila CRI 14, the causative agent of goldfish (Carassius auratus) hemorrhage disease, could not produce detectable siderophore when incubated at iron limited medium and analyzed by the chrome azurol S method. This strain produced clear orange halos around its colonies on blue agar only after 2 weeks of incubation, whereas it reaches the plateau phase after 36 h of incubation in goldfish serum. Incubating 1 ml of fish serum with the extracellular proteins of 1 ml culture of CRI 14 at 37 for 30 min., the transferrin-bounded iron contents decreased from l.5g•ml·1 to 0.9g·mt-1 and 1.3 g•ml·1 to 0.45g•ml·1 for goldfish and bighead (Aristichthys nobilis), respectively, and the iron binding capacity also decreased from 2.3g·ml·1 to 1.8g•m}·1 and 2.7g•ml·1 to 1.0g·ml·1 for goldfish and bighead, respectively. An in situ iron-binding experiment after polyacrylamide gel electrophoresis (PAGE) further showed that both iron-binding and free transferrin have been digested by A. hydrophila protease. These results showed that A. hydrophila protease can compensate its inadequacy of siderophore for iron.
Effects of the Aromatase Inhibitor Fadrozole on Gonadal Development in Coho Salmon, Oncorhynchus kisut
Authors: HONG W. , DONALDSON E.M.
Published: October 2022

The effects of the aromatase inhibitor fadrozole on oogenesis, spermatogenesis and gonadal development in coho salmon Oncorhynchus kisutch were investigated. Both fe. males and males were implanted intraperitoneally with single silicone pellets containing the aromatase inhibitor fadrozole (CGS 16949A) at dosages of 10 mg•kg·1, 100 mg•kg·1 and 500 mg• kg·1, respectively. After 44 d, histological examination showed that females treated at dosages of 100 mg•kg·1 and 500 mg•kg· 1 had gonads with atretic oocytes. Conversely, control females had ovaries filled with synchronously developing oocytes. Both average ova­rian cross-sectional areas and average oocyte diameters in the treated groups were smaller than those in the control. It is suggested that the aromatase inhibitor fadrozole affected oo­genesis and ovarian development in coho salmon. The results did not show any significant differences in spermatogenesis and testicular development between treated and control males, except for the males which received a dosage of 100 mg·kg·1, a small number of which had testes which were further developed than those in the control.

O objetivo deste estudo foi analisar a presença de elementos utilizados pelo Jornal Nacional (JN) para conferir dramaticidade na cobertura da pandemia de Covid-19, a partir do olhar da dramaturgia do telejornalismo. O recorte compõe nove edições do telejornal entre o período de abril de 2020 e junho de 2021, dos quais extraímos técnicas e ferramentas usadas não só em reportagens, mas na apresentação do noticiário, bem como em quadros temáticos e editoriais. Como processo metodológico, utilizamos os conceitos de telejornalismo na atualidade e dramaturgia do telejornalismo, além do método da Análise da Materialidade Audiovisual (COUTINHO, 2016), que tem como objetivo observar a totalidade da informação como unidade (texto+som+imagem+tempo+edição). Identificamos tentativas por parte do JN de oferecer um discurso mais sensível e eficiente diante da enxurrada de informações e desinformações sobre a pandemia. Os elementos que conferem dramaticidade foram encontrados nas falas dos repórteres, apresentadores, entrevistados, nas imagens tanto captadas pela emissora ou pelo público e também nas artes, nas pausas sonoras, nos sobe sons. As situações características da dramaturgia do telejornalismo foram ainda localizadas nas narrativas, através da presença de heróis/mocinhos, vilões/bandidos, vítimas dos vilões/bandidos e nas situações de conflito mostradas nas notícias.

Published: October 2022

The coal industry is leading in China. The further five-year development plan implies the coal industry capacities growth, but at the same time, it is planned to follow the path of “clean and efficient use of coal”. One of the priority areas is “green” construction. In this regard, the issue of disposal of coal burning waste is acute, the volume of which is constantly increasing, thereby polluting the soil, atmosphere and nearby reservoirs. Inefficient thermal insulation is the main reason for the large overspending of energy for heating buildings and structures. The harsh climate and cold winters in some areas of China predetermine the necessity of using high-quality heat-insulating materials. One of such materials is gas concrete. However, along with heat insulation it should also perform soundproofing function to minimize the noise exposure of big-city residents. It is noted that the production of aerated concrete mixes occupies a leading position, and the use of waste from fuel combustion as one of the components of aerated concrete allows not only to reduce the cost of its production, but also to reduce the environmental burden on the environment.
CONSTRUCTIONS SYNTHESIS OF PIVOTAL SYSTEMS

The characteristic features of the supporting structure are its topology, geometry and parameters of the elements. The process of creating a structure goes from the project to its material embodiment. The topology defines the contour of the load resistance, which finally manifests itself in the configuration and material. The fundamental beginning of the design project is the variational principle of structural synthesis with energy content. It provides a minimum consumption of material. Its fundamental distribution is made at the stage of topology design as a confrontation with an external force field. Geometry is more subordinated to directive settings related to the nature of the load and the functional purposes of the structure. The parameters of the elements complete the definition of the configuration, ensuring satisfaction of the conditions of strength, rigidity and stability of equilibrium. The scientific results concerning the consideration of the influence of configuration on the operational qualities of the structure and the approach to the practical theory of structural synthesis are used. A four-rod system is chosen to illustrate the design methodology. The regulation of strength and stiffness parameters can be effectively carried out when using composite materials, in particular, fiber-reinforced concrete, since the change in strength is correlated with the parameters of the fibers and their percentage with a slight change in the modules of the material.

Published: October 2022

The cement industry has unique opportunities to address the issues of utilization of manmade raw materials and municipal waste. The problem of using alternative fuels in the technological process of cement production is usually due to their low calorie content. The above calculations show the possibility of using RDF fuel as part of a mixed fuel when it is burned under conditions of an increased oxygen content in the air. Reducing the volume of combustion products increases the temperature of the torch, which increases the productivity of the cement rotary kiln, mixed fuel can be used in both low – and high-temperature zones of cement kiln units with an optimal ratio of components. There are restrictions on increasing the concentration of oxygen in the air, due to a decrease in the actual combustion temperature of the fuel due to the reverse reactions of the decomposition of combustion products and violations of the high-speed modes of operation of suspension heat exchangers. In addition, an increase in oxygen in the air significantly reduces the thermal efficiency of the clinker cooler as a result of the increase in excess air volumes. The use of RDF fuel in the optimal ratio allows replacing up to 42 % of natural gas.
РІЗНОМАНІТТЯ ГЕНОМІВ В ООЦИТАХ ГІБРИДНИХ ЗЕЛЕНИХ ЖАБ PELOPHYLAX ESCULENTUS (ANURA: RANIDAE) В ГЕМІКЛОНАЛЬНИХ ПОПУЛЯЦІЙНИХ СИСТЕМАХ В УКРАЇНІ
Authors: Fedorova A. , Shabanov D.
Published: October 2022

Pelophylax esculentus (геном позначається як LR) є міжвидовим гібридом ставкової жаби Pelophylax lessonae (геном LL) і озерної жаби Pelophylax ridibundus (геном RR). Розмноження гібридів в типовому випадку відбувається за рахунок клональної передачі одного з батьківських геномів. Гібриди зазвичай співіснують з одним або обома батьківськими видами в так званих геміклональних популяційних системах (ГПС). Гібриди можуть продукувати гамети обох батьківських видів окремо або одночасно (суміш гамет L і R). Деякі гібриди також утворюють диплоїдні гамети різного геномного складу, суміш гаплоїдних і диплоїдних гамет, а також гамети з частково рекомбінантними геномами. Метою дослідження було ідентифікувати типи гамет, які продукують самки P. esculentus з українських ГПС шляхом аналізу алозимів ЛДГ-1 з їх ооцитів. Особливу увагу ми зосередили на двох типах ГПС із басейну річки Сіверський Донець, де гаметогенез самиць детально не вивчався. Було проаналізовано 19 самок жаб (шістнадцять P. esculentus і три P. ridibundus в якості контролю) із шести різних місцевостей. Ідентифікацію алозимів ЛДГ-1 проводили за швидкістю їх міграції до аноду. Ідентифікацію активності ферментів проводили кінетичним УФ-методом. Ми показали, що гібридні самки з RE-HPS можуть передавати геном R у своїх ооцитах і підтвердили припущення, що триплоїдні самки з R-Epf-HPS продукують ооцити з геномами L. Жаби з R-E-Ep-HPS і L-E-R-HPS продукували ооцити з геномами L або R, що підтвердило попередні дослідження цих типів популяційних систем. Вимірювання активності ЛДГ показало, що активність R-аллозиму приблизно в 1,6 разів вища, ніж L-аллозиму. Не виявлено відмінностей в активності алозимів для різних типів геміклональних популяційних систем.

General and specific traits in the folklore and ritual life of the peoples of the Caucasus (ethnolinguistic aspect)
Authors: BESOLOVA Elena , BEKOEVA Irina , BALIKOEVA Marta
Published: October 2022

The article deals with the cultural connections between the speakers of Caucasian and Iranian(Ossetian) languages which reflect the flexibility of the language as well as cultural values and preferences. These connections are revealed through main rituals such as the ritual of killing old people to prevent them from a disgraceful death by age, funeral and wedding rituals, as well as ritual object and their names. The authors aim at establishing the common and unique traits in the ritual and cult life of the peoples of the Caucasus. The research proved that the life of the Caucasian peoples constituted a cultural unity. It was determined both by the internal life of the peoples and the common source of cultural and language loan, namely the multilanguage Caucasus inhabited by Iranian, Caucasian, Turkic, Arabic and Indo-European language speakers. The authors underline and analyse the resemblance of different elements of rituals and study the linguistic parallels in ritual and cult texts. The comparative -typological analysis reveals many common traits in the studied rituals, the verbal representation of which reflects to which extent the traditional values are preserved in the culture and contributes to interpretation of the semantics and symbolic of the ritual text.
A synthetic worldview of inflexive becoming in the face of perinatal mourning

Published: October 2022

Today, focusing on maternal mourning due to perinatal death, in order to understand a devastating phenomenon for parents and particularly for the mother, due to the loss of a child, is a homeostatic milestone. The objective of the present is to comment on an inflectional arc about the emotional adaptive changes in women and after pregnancy and the frustration of motherhood, which this loss entails. The grieving process must be interpreted through the different phases that characterize it and that can manifest in a linear way or behave as a dynamic process that changes from one phase to another. In these conditions, the approach of the health professional is important and must be based on a concatenation of empathy with the mother in the process of mourning, which contains ethical, philosophical and sociological connotations, which must be taken into account in all health management. For mothers in this situation, it is useful to have self-help or support groups, in order to highlight this sad experience and, at the same time, be allowed to interact and be supported by other mothers who have witnessed such an unfortunate experience.

Published: October 2022

The hydrophobic coatings are one of the most used processes to prevent the deterioration of materials and increase its lifetime, since they have non-stick, low friction, anti-wetting, high and low temperature resistance, chemical and dielectric properties, etc. This work presents the chemical production of zinc oxide (ZnO) nanostructures that were deposited on glass substrates by two methods: spin-coating and dip-coating. The doped substrates were modified by temperature and exposure to ultraviolet light (UV). The contact angle of the surface was measured after making some modification, revealing an initial change compared to the uncoated substrate. Later, the angles were varied, comparing between the two deposition methods. The higher contact angle was presented by spin-coating sample, after rising its temperature and a first exposure to UV light; an increase of 30% was observed in comparison to the uncoated substrate; In contrast, the smallest angle was obtained in dip-coating sample after raising its temperature, reducing around 55% of its size compared to the uncoated substrate.

The objective of this article was to identify the variables that make up the Learning Styles of Higher Education students from different States of Mexico. The methodology used was quantitative, synchronous, and cross-sectional exploratory and descriptive. The collection of information was carried out by means of a standardized instrument from Spain, it was applied to 1412 people. The instrument consists of two sections, in the first are the general data, the second section mentions the technique of natural semantic networks and the third section corresponds to the dimensions of Learning Styles. The importance of the present project lies in the need to know the way in which students acquire and process the acquired learning, in order to provide them with the appropriate tools for a greater understanding and construction of their own knowledge. In the students aspects of deep processing are observed, which make this one an analytical and assertive thinker in the methods of study that he carries out to obtain knowledge and give rise to self-affirmation. Students through the implementation of strategies must develop their skills, abilities and competencies.

The AISI 316L steel is a material used to manufacture prostheses and medical instruments due to its high corrosion resistance. However, its wear resistance is low, but it can be improved by synthesizing thin films of titanium nitride (TiN) on the surface. This compound is a hard material that improves its tribological and corrosive properties, in addition to presenting good adhesion to the substrate. In this work, a Ti/TiN thin film was obtained using the Physical Vapor Deposition (PVD) technique. This coating was characterized by scanning electron microscopy, energy dispersion spectroscopy (EDS), and light microscopy; additionally, tribological tests under wet conditions and adhesion tests were conducted. The coating showed good adhesion to the substrate according to the VDI standard. In tribological tests, a low coefficient of friction vs. a polyethylene pin in a wet environment (bovine serum) was obtained. The EDS showed a high concentration of Ti and N on the substrate even after wear tests.

The term self-regulation learning refers to the process through which studentsdevelop their own thoughts, feelings, and behaviors in order to better their ownlearning outcomes. However, in light of the students' EFL speakingencouragement, a small empirical study examines the relationship betweensocial self-regulated learning and cognitive awareness. The study's goal becameclear when the data was analyzed thematically. A top-down analysis wasperformed on the data received from the five participants. Massive oralcommunication in English as a foreign language (EFL) performance can beimproved by encouraging students' self-and social-psychological elements.
TikTok: possibilidades de gestos críticos no ambiente virtual
Authors: Pereira Sônia Virginia Martins , Da Silva Everton Henrique Souza
Published: October 2022

Ao navegarem nos espaços digitais, os sujeitos não recebem passivamente as informações. Eles têm, com considerável facilidade, o papel de escrileitor, conforme proposto por Paveau (2021) - leem e escrevem sobre o que está em circulação. Tal conjuntura permite a determinados teóricos defenderem a indissociabilidade entre as ações sociais do homem e a máquina atualmente. Por essa via, diversificadas plataformas populares, como o TikTok, mídia social chinesa, permitem, com seus recursos tecnológicos, a criação e circulação de práticas de linguagens que fomentam o debate de diversos temas e marcam posições ideológicas, num percurso de escrileitura. À vista disso, esta pesquisa objetiva refletir de que modo os discursos presentes nesse ambiente virtual instigam e contribuem para (des)construção de posicionamentos ideológicos, em cadeias discursivas. Sendo assim, nos apoiando numa fundamentação teórica composta por noções da análise dialógica do discurso, análise do discurso digital e da perspectiva de letramento crítico, analisamos  posicionamentos em processos enunciativo-discursivos de postagens sobre dois temas recorrentes e seus comentários. A partir disso, compreendemos que, ao se constituir em arena discursiva, o TikTok corrobora para discursos performativos acerca de fatos e temas sociais, o que abre espaço para que interlocutores, em seus papéis ativos-responsivos, efetuem o processo de letramento crítico para ratificação e refutação de ideias, um traço do escrileitor, em seus movimentos enunciativos multissemióticos.

Hubungan pola asuh pemberian makan dan skor keragaman pangan dengan kejadian stunting pada balita usia 24–59 bulan
Authors: Suryawan Aisha Excelia , Ningtyias Farida Wahyu , Hidayati Manik Nur
Published: October 2022

Latar Belakang: Stunting merupakan kegagalan tumbuh kembang anak yang diakibatkan kurangnya asupan zat gizi kronis dalam periode waktu yang panjang. Salah satu dari empat penyebab utama stunting adalah masalah penerapan pola asuh orang tua yang salah. Skor keragaman pangan dapat dijadikan sebagai acuan untuk menentukan kualitas makanan yang dikonsumsi oleh balita. Berdasarkan data Riskesdas tahun 2018, prevalensi stunting di wilayah Kabupaten Lumajang sebesar 34,01%. Kejadian stunting tertinggi pada tahun 2019 dan 2020 berada di Wilayah Kerja Puskesmas Klakah. Tujuan: Menganalisis hubungan pola asuh pemberian makan dan skor keragaman pangan dengan kejadian stunting pada balita usia 24–59 bulan di wilayah kerja Puskesmas Klakah. Metode: Penelitian ini menggunakan desain cross sectional yang dilakukan pada bulan Agustus tahun 2021. Populasi dalam penelitian ini adalah seluruh anak balita berusia 24–59 bulan yang tinggal di wilayah kerja Puskesmas Klakah, Kecamatan Klakah dengan besar sampel sebanyak 43 orang. Pengambilan sampel dilakukan dengan teknik cluster sampling. Variabel yang diteliti adalah pola asuh pemberian makan dan skor keragaman pangan. Pengambilan data menggunakan pengukuran antropometri, kuesioner pola asuh pemberian makan, dan kuesioner Individual Dietary Diversity Score (IDDS). Hasil: Pola asuh pemberian makan tidak berhubungan dengan kejadian stunting (p=0,127) dan skor keragaman pangan berhubungan dengan kejadian stunting (p=0,027; OR=5,143). Kesimpulan: Tidak terdapat hubungan antara pola asuh pemberian makan dengan kejadian stunting pada balita usia 24–59 bulan di wilayah kerja Puskesmas Klakah dan terdapat hubungan antara skor keragaman pangan dengan kejadian stunting pada balita usia 24–59 bulan di wilayah kerja Puskesmas Klakah.

Published: October 2022

Face detection in digital photos aims to get the face area in the photo. Problems often occur when detecting faces, namely there is a lot of noise in digital photos so that it affects the detection process. Therefore, in this study apply the median filtering method to improve digital photos by reducing noise in the photos to be tested. The advantage of using this filter is to keep the edges smooth while reducing noise which aims to improve image quality. The ability of this method is measured using the parameters of Mean Square Error (MSE) and Peak Noise to Signal Ratio (PNSR). When the MSE value obtained is low and the PNSR value obtained is high, the results can be said to be good. The method used to detect faces in this research, viola-jones, was chosen because it is one of the face detection procedures with a high level of accuracy and good computational ability. The sample used in this study consisted of 10 digital photos taken using a Samsung A11 smartphone camera with a resolution of 13 mega pixels and 8 mega pixels in JPEG format. The results obtained in this study are the best error values in MSE 0.9517 and PSNR 24.2804. Based on these results, it can be concluded that the mean filtering method is feasible to be used in the case of face detection in this digital photo
