Authors: Anto Lie , Khosama Herlyani , Kembuan Mieke
Published: February 2022

Background: Excessive smartphone use affects sleep quality. The purpose of this study was to see the relationship between smartphone usage and sleep quality.Methods: Respondents were selected consecutively and asked to fill out the smartphone addiction scale-short version (SAS-SV), Pittsburgh sleep quality index (PSQI) questionnaires via google form and measure sleep quality objectively with sleep tracker (Fitbit charge 2™). Datas were analyzed using SPSS version 25.Results: There were 62 subjects included in this study, the majority were women (74.2%), the average age was 21 years old. A total of 69.4% are addicted to smartphones. Assessment with PSQI found that 71% showed poor sleep quality, while with Fitbit charge 2™, good sleep quality was obtained, namely sleep latency (100%), sleep efficiency (75.8%), light sleep (61.3%), and deep sleep (82.3%). Waking 5 minutes (50%) is uncertain. Poor sleep quality, namely wake after sleep onset (WASO) by 77.4% and rapid eye movement (REM) by 59.7%. The relationship between smartphone addiction and subjective sleep quality (PSQI) was significant at p=0.007. Smartphone addiction and sleep quality measured by objective parameters seemed insignificant (wake up 5 minutes p=0.884, WASO p=0.848, sleep efficiency p=701, light sleep p=0.629, deep sleep p=0.240, REM p=0.638).Conclusions: There is a relationship between smartphone addiction and sleep quality using subjective measurement (PSQI), but not with a sleep tracker.

Published: February 2022

Background: Tuberculosis (TB) is the infection of global health concern. The management of TB is a 6-month course of anti-TB drugs. Compliance is crucial for curing TB. Adverse effects often affect the compliance negatively. One of the adverse effects affecting TB treatment outcome is anti-TB drug induced hepatotoxicity (DIH). Therefore, the purpose of this study was to assess the incidence of anti-TB DIH and its associated factors among newly diagnosed TB patients.Methods: A single centre prospective study was conducted from January-December 2020. All patients who were newly-diagnosed for TB, started anti-TB medication and diagnosed with drug-induced liver injury during anti-tubercular treatment included in the study.Results: Total of four hundred and ninety-two (492) TB patients taking anti-TB drugs were involved in this study with male predominance and maximum in the age group of 30-45 years. Smear-positive pulmonary TB accounted for 66.9% of all cases. During the study period, 9.3% TB patients developed anti-TB DIH. Among the cases of anti-TB DIH, female patients account for 52%. Patients with extra-pulmonary TB (n=23), low BMI (n=16), alcohol consumption (n=21) had developed anti-TB DIH. The time interval from the initiation of treatment to the onset of hepatotoxicity was 16-45 days.Conclusion: The chances of hepatotoxicity among TB patients taking anti-TB drugs are always there. Thus, it is necessary to monitor liver function in patients receiving anti-TB drugs routinely.

Este artículo se enfoca en el estudio de las estrategias empleadas por el gobierno virreinal durante la guerra de Independencia para controlar el territorio comprendido entre Orizaba y Veracruz. La investigación se planteó desde la óptica de la historia regional, con base en documentación original localizada en archivos de México y España, y la revisión de diversos autores decimonónicos y contemporáneos, con el propósito de analizar las medidas instrumentadas por el virrey Juan Ruiz de Apodaca para pacificar la provincia de Veracruz, tales como el otorgamiento masivo de perdones y la formación de colonias de indultados, el repoblamiento de pueblos abandonados, y el establecimiento del hasta hoy poco conocido “camino militar” del trayecto Córdoba-Veracruz, puesto en operación en la etapa final del conflicto.
IMPROVING THE EDUCATION PROCESS BY INTRODUCING INDIVIDUALIZATION AND DIFFERENCE IN PUPILS OF THE 1ST PRIMARY SCHOOL
Authors: Semradova Monika
Published: February 2022

The article focuses on the current trend of increasing the quality of education, which brings increased demands on the competencies of teachers in the introduction of differentiated teaching in primary school pupils in a heterogeneous complex class, from the very beginning of schooling. In its Strategy for the Educational Policy of the Czech Republic until 2030 +, the Ministry of Education emphasizes didactic procedures in teaching, which will enable differentiation of teaching according to the needs of pupils. However, many teachers are not sufficiently prepared for this and there is very little relevant literature and research to help them in practice. The article summarizes the latest findings in this area, analyzes the concept of internal differentiation, not only its cognitive aspects, but also the social dimension of teaching. It emphasizes the importance of this issue for improving the primary level of primary school in contemporary socio-economic contexts of equal educational opportunities in society. It emphasizes the knowledge of specific students and their individual peculiarities as an important condition for the implementation of internal differentiation. It also discusses the possibilities of differentiation in relation to the content of education, methods and organizational forms of teaching. It brings a list of pedagogical means through which differentiated and individualized teaching is implemented in the teaching process. Improving the level of basic education through internal differentiation of teaching is a long-term and difficult task due to the growing heterogeneity of numerous school groups. The main goal of the research was to map the introduction of differentiated and individualized teaching for five teachers in five primary schools in the Pardubice, Central Bohemia and Hradec Králové regions, focusing on the main subjects of the Czech language and mathematics in 1-3. elementary school class. In our article, we present an analysis of the research survey of the first stage of research, in the first classes of a selected sample of teachers who use differentiated teaching to a greater or lesser extent and the mentioned years will succeed for three years of schooling. In the first stage of the research, we will focus primarily on the use of pedagogical means of differentiation and individualization and their impact on student outcomes and the effectiveness of the teaching process.

Foreword: Territorial governance in the Western Balkans: Multi-Scalar approaches and perspectives
Authors: Cotella Giancarlo , Toto Rudina
Published: February 2022

Since the beginning of the 1990s, the Western Balkans have embarked on a complex path of transition and societal transformation, that was intended to eventually lead to their integration into the European Union. The pace of this process has, however, varied, with some countries already having acquired membership, while others still struggling. Territorial governance plays a particularly important role in this process, as the internal cohesion of the region is key to its successful integration into the EU. However, knowledge on territorial governance in the Western Balkans is still limited and fragmented. This special issue aims to shed some light on the matter, discussing territorial governance contexts and practices in the Western Balkans from a multi-scalar perspective. This editorial serves as an introduction to the special issue, framing its context and guiding the reader through the articles that follow.

Authors: Hencelová Petra , Križan František , Bilková Kristína
Published: February 2022

The aim of the paper is to evaluate alternative food networks (farmers’ markets and community gardens) in Slovak towns in order to determine the views of town self-governing authorities. Data was collected through a questionnaire sent to representatives of towns. The results have shown that only 39% of towns regularly organise farmers’ markets but, overall, 52% of towns support or plan to support their organisation. There are a total of 40 community gardens in 17 towns, mainly in the west of Slovakia. The paper discusses the ways in which Slovak towns support alternative food networks.
Kompetencje pedagogiczne nauczycieli wczesnej edukacji – relacja z badań własnych
Authors: Szkolak Anna
Published: February 2022

In my article I deal with the problems connected with the debate on the Polish teacher condition in the situation of the system transformation, changes in the Polish school and new challenges which it faces. The particular role in this process, I ascribe an early childhood education teacher and I pose the questions on how this teacher is equipped as far as his or her pedagogical competences are concerned. I also take into consideration the subject matter of the teacher professional development and also internal factors (personality, burnout syndrome) and external factors (professional advancement, didactic staff mutual relations, school localization), which are in respect to these competences. Formulated problems and assumed hypotheses have become the starting point for empirical research carried out in the properly selected environments (town and rural). A group of 529 teachers took part in this research whose professionalism was valued on the basis of self-assessment and observation results made by 101 headmasters. The obtained empirical documentation is the base for quantitative and qualitative analysis of indexes determining the level of selected „pedagogical competences” and factors conditioning these competences. The research results gave the empirical material proving the fact that early childhood education teachers present a good level of professional pragmatic competences, communicative-interpretative and cooperation competences, on the other hand, their creativity competences and computer science and media competences turned out to be worse. This diversity creates important circumstances which induce to carry out further research.

Religião e política na trajetória intelectual de Friedrich Engels
Authors: Ribeiro Wallace Cabral
Published: February 2022

Friedrich Engels deixou uma interessante e original contri-buição aos estudos dos fenômenos e fatos religiosos em suas dimensões políticas, históricas, sociológicas e filosóficas. Apesar de significativas, do ponto vista qualitativo ou quantitativo, suas contribuições sobre o tema são desconhecidas e pouco mobilizadas, inclusive no interior do marxismo, que constantemente abrevia o debate sobre o fenômeno religioso à expressão “ópio do povo”. Pensando nesse aspecto, este artigo tem por objetivo identificar e analisar as reflexões de Engels em torno da articulação entre religião e política ao longo de sua trajetória enquanto intelectual e militante socialista. Para alcançar os objetivos delimitados, nos debruçaremos sobre os escritos de Engels (artigos, ensaios e livros) para, assim, localizar as reflexões em torno das questões políticas e religiosas, compreender o contexto de elaboração das ideias, os embates políticos e as mudanças em seu modo de pensar o fenômeno político religioso durante sua trajetória. O artigo também contemplará, de modo paralelo, alguns aspectos biográficos que nos possibilitarão conhecer um pouco mais do autor e sua inserção no debate sobre o fenômeno religioso.
An integrated income and management model for internationalization
Authors: Jiménez Carlos Silverio Huerta , Albo Marco Velázquez
Published: February 2022

Since its conception almost three decades ago, internationalization of higher education has seen the development of organization models for internationalization at institutional level. However, based on a literature analysis of the most cited models, what remains to be developed are institutional funding frameworks to support internationalization activities. This article proposes a model for the acquisition and management of funds for the internationalization of higher education institutions. It has the premise that an institutional integrative system can generate more resources than one that is not institutionally integrative. A strategic application of the model is discussed as an example for its application at institutional level. This model provides practical implications for strengthening internationalization efforts at higher education institutions.

Published: February 2022

Eel (Anguilla sp.) is a fish that is classified as having a high economic value, with the level of distribution in almost all of Indonesia. The Timang Tideng River is one of the rivers located in the village of Kamaifui, Alor Regency, but until now, there has been no scientific report on the distribution of eel (Anguilla sp.) in the Timang Tideng River, Alor Regency, NTT. This study aims to determine the type and size of eel found in the Timang Tideng River. The research was conducted from March to April 2021 at three observation stations. Eel fishing is done at night considering its nocturnal nature. The fishing gear used is fishing rods and chicken stomachs as bait. Measurements of physical and chemical parameters of the waters were carried out simultaneously during the fishing process including temperature, pH, and current speed. The results showed that there were two types of eel in the Timang Tideng River, namely A. marmorata as many as 24 individuals and A. celebesensis as many as 1 individual. The eels found were in the yellow eel phase, with a total length range of 40-72 cm and a total weight ranging from 126-994 g.
Influence of Ca on the mechanical properties and microstructures of slag-fly ash geopolymers
Authors: Li Jing , Yang Lang , Rao Feng , Liu Wenbiao , Ma Hang , Chi Xiaopeng , Zhong Shuiping
Published: February 2022

A deep understanding of the role of Ca in geopolymers exposed to various environments is essential for geopolymerization. This work evaluates the role of Ca by observing the behavior of hierarchically calciferous geopolymers under different environments including air, carbonization and freezing-thawing cycles. The structural and morphological differences between the geopolymers and the related mechanisms in various environmental conditions are assessed based on compressive strength, brunauer emmett teller, X-ray diffraction, fourier transform infrared spectoscopy, nuclear magnetic resonance spectroscopy and scanning electron microscopy measurements. It is found that two kinds of geopolymer gels, calcium silicate hydrate and sodium aluminosilicate hydrate, are formed in the geopolymerization of blast furnace slag and fly ash. Regardless of the specific air, carbonization or freezing-thawing cycle environment, the former gel dominates the properties in low Ca geopolymers, while the latter gel determines the properties in medium and high Ca geopolymers. Moreover, the carbonization environment enables calciferous geopolymers with higher surface areas and smaller pore sizes. Such adequate pore structures can significantly improve the performance of the geopolymers. This study presents novel insights into the influence of Ca on geopolymerization and in strengthening geopolymer properties.
Modelling the Impacts of Agricultural Outputs and its Components on Human Mortality Rate in Nigeria
Authors: Olaniran Olukunle , Ogunjinmi Olusola
Published: February 2022

Does agricultural activity affect human mortality? This research paper provides an empirical analysis on this important question by separately regressing agricultural outputs and its components on human mortality rate in Nigeria over the period 1981–2019. Employing the autoregressive distributed lag estimator, a long run relationship exist between agricultural outputs and human mortality rate in Nigeria. Regarding the parameter estimates, findings showed that the indirect relationship between agriculture outputs and mortality is statistically insignificant in the long run. More so, in the short run, the current level of agriculture outputs reported a significant positive coefficient whereas the first lag has a significant negative parameter. Concerning the agriculture components, in the long run, fishing activity negatively and significantly influenced human mortality whereas forestry activity directly impacted on human mortality rates. The influence of both crop and livestock productions on mortality rate is not statistically established in the long run. The study therefore suggests the need for government to adopt pro-poor policies that is capable of improving investments in agricultural activities by both public and private sectors so as to curtail human mortality rate in the country.

Authors: Delpuech Xavier , Gorioux Henri , Pouxviel Guilhem
Published: February 2022

À la suite de l'interdiction des traitements aériens en 2015, les traitements phytosanitaires dans les vignobles de forte pente sont majoritairement réalisés par des opérateurs, soumis à une pénibilité du travail importante, à des risques accrus d’exposition aux produits phytosanitaires, ainsi qu’au risque d’accidents (renversement des engins). La pulvérisation par drone pourrait constituer sur ces parcelles non mécanisables une alternative aux traitements au sol. Le projet PULVEDRONE a permis d’évaluer la qualité de pulvérisation par drone lors de 3 années d’essais de 2019 à 2021 (Ardèche, France).

Authors: Violante Susana , Durán Laura Carolina
Published: February 2022

El presente artículo pretende realizar un análisis reflexivo, tomando como base las conceptualizaciones de Miranda Fricker, haciendo hincapié en el lugar y la condición otorgada a diversas mujeres en la Antigüedad Tardía y en la Edad Media. Se propone revalorizar a algunas pensadoras que han generado diversos tipos de producciones, de las cuales se conservan documentos para su estudio y, así, rescatarlas de un olvido las más de las veces tendencioso, del que han sido objeto en la implementación de sistemas de opresión que se interrelacionan en los discursos de silenciamiento. En este sentido, el artículo presenta una revisión de los parámetros habituales de la educación filosófica que ha contribuido a su olvido y / o negación. El propósito de esta revisión es promover el desarrollo de una comprensión más amplia y abarcadora de las múltiples formas de vida y pensamiento desplegados en la Antigüedad Tardía y la Edad Media.

Authors: Lourenço da Silva de Oliveira Pedro Celeste Maria
Published: February 2022

The case study is presented in the title: Hrabanus Maurus’s (ca. 780-856) In honorem sanctae crucis (ca. 810) and Berthold of Nuremberg’s two-part work Liber de misteriis et laudibus sancta crucis (1292) and the supplement Liber de misteriis et laudibus interemerate Virginis genitrices Dei et Domini nostril Ihesu (1294)) are confronted and dissected; and the use of the word “transformation” is key to the analytical and interpretive possibilities concerning the medieval formulas the author presents (both textual and imagetic). Close to five hundred years separate the carmina figurata of the Carolingian abbot and the text-images of the Dominican lector and both follow on antique traditions. With more than two hundred pictures of diagrams and illuminations from a multitude of codices, architectural details and religious objects, Hamburger furnishes our understanding of transformation in medieval visual cultures (largely beyond Hranabus and Berthold’s) and of the centrality of diagrams in artistic productions.
Privilege of Voice as a Criterion for Sociolinguistic Inequalities
Authors: Weirich Anna-Christine
Published: February 2022

Drawing on a theoretical framework for describing sociolinguistic inequalities with the notions of scope and access, the idea of voice can be used to define the aim of language learning processes as strategies to overcome sociolinguistic inequalities and marginalization. Understood in the metaphorical use of “being able to speak” and “to be heard” as used by Dell Hymes, having a voice must be analyzed from an intersectional perspective as a privilege. Studying the example of a mobile speaker and her successive attempts to find voice in different linguistic relations, reveals that the listener and their attitude have to be included in discussions of the conditions for having voice. For the rigor of sociolinguistic arguments, voice should be reserved for use on an abstract level while drawing on other (sociolinguistic) notions in empirical analysis that can describe concrete manifestations of linguistic inequalities.
Derrière la langue, les positionnements sociaux. Pouvoir faire entendre sa voix en langue seconde
Authors: Ben Harrat Malika , Zeiter Anne-Christel
Published: February 2022

Les théories de la socialisation langagière mettent en évidence le rôle fondamental de la possibilité de faire entendre sa voix pour accéder aux pratiques sociales. Afin de mieux comprendre cette idée, nous penserons ici la voix en termes de positionnements énonciatifs liés aux représentations sociales qui structurent l’agir social de la personne. Après avoir dressé notre cadre théorique qui articule apprentissage de la langue, socialisation et réflexivité, nous présenterons trois types de positionnements socio-discursifs qui, sur le modèle de Van Langenhove et Harré (1999), rendent compte des dynamiques interactionnelles et des relations de pouvoir qui s’y matérialisent. Nous poserons enfin l’hypothèse qu’un travail réflexif mené en classe de langue sur les représentations sociales et les positionnements est susceptible d’améliorer la voix des personnes conduites à agir socialement dans un nouveau contexte social et langagier.
Ubiquité et discrimination des voix en centres d’appel : la quête illusoire et paradoxale d’un assureur en France et au Maghreb
Authors: Cuisance Marie-Laure
Published: February 2022

À partir de données ethnographiques produites sur la mise en place de centres d’appel en France et au Maghreb par un groupe d’assurance français, l’article aborde la notion de « voix », comme objet et outil d’analyse, pour dévoiler les mécanismes de légitimation de ses locuteurs. Il permet de montrer que la poursuite d’un objectif de rentabilité économique de l’interaction par la professionnalisation, la standardisation et la délocalisation des voix de ses salariés ne produit pas les effets escomptés. Des phénomènes de discrimination et de domination agissent par et sur ces voix, indissociables des espaces sociaux dans lesquels elles sont produites et entendues.
Asymmetric effects of diesel prices and exchange rates on turkey's food prices
Authors: Kadanalı Esra
Published: February 2022

This study analyses the asymmetric effects of the swings in diesel prices and exchange rates on Turkey’s food prices with the Non-Linear Autoregressive Distributed Lag (NARDL) model. For this purpose, Turkey’s diesel prices, exchange rate, and general food price index data for the same period between January 2000 and December 2019 were adopted. Considering that diesel prices are an essential cost item in agricultural production, it becomes crucial to determine the effect on food prices. Besides, the exchange rate fluctuations are expressed as another important macro variable that impacts food prices. As a result of the NARDL model, asymmetric co-integration between the general food price index, diesel prices, and the exchange rate was determined. Still, it has been observed that the negative and positive changes in diesel prices on food prices, in the long run, do not have a significant effect. On the other hand, the negative effect of the exchange rate was significant. It is concluded that a 1% decrease in the negative changes in the exchange rate will cause 0.94% decrease in food prices. Consequently, the general food price is affected by adverse shocks on the exchange rate in the long run. One may be concluded that the exchange rate should be considered while formulating policies about the swings in food prices. Especially, the local production of agricultural inputs affected by exchange rate fluctuations could be encouraged.
Effect of supplementation of nano zinc in male quail diets on performance, some blood parameters, testis morphology and meat colour properties
Authors: Sevim Behlül
Published: February 2022

This research was conducted to determine the effects of different levels (0, 50 or 100 mg/kg) of nano zinc (nano Zn) supplementation as a zinc source in male Japanese quail (Coturnix coturnix Japonica) diets on performance, some serum parameters, testis characteristics and meat colour. In the four-week study, a total of 60 male Japanese quails (190.4 ± 2.4 g body weight) at the age of 49 days were distributed to three treatment groups and each treatment group was divided into four subgroups, each containing five male quails. As a result of this study, in the current study, the addition of nano Zn to the diet had no effect on feed intake, testis morphology, serum cholesterol, total protein, calcium and phosphorus levels (P>0.05). Addition of nano Zn to diet increased body weight gain (BGW) (P<0.05). With the addition of nano Zn, serum glucose level increased while serum triglyceride level decreased (P<0.05). Breast and thigh + drumstick L* values among meat parameters increased with the addition of nano Zn to male quail diets (P<0.05). As a result, adding nano Zn to male quail diets increased serum glucose level and meat L* value, decreased serum triglyceride concentration, and testis morphology was not affected.
The concentrations of Zn and Cd in soil and corn plants affected by phosphorus fertilization in a long-term field experiment
Authors: Kovačević Dragan
Published: February 2022

Intensive application of nitrogen and phosphorus fertilizers can lead to negative consequences, such as a decrease in Zn content, as well as an increase of Cd in plants. In a long-term field experiment, we studied the influence of the increasing doses of phosphorus fertilizers on the concentration of Zn and Cd in the soil and corn plants (stem and leaves). The obtained results show that the application of the increasing doses of phosphorus significantly decreased the pH reaction of the soil, but did not affect the amount of total and potentially available Zn in the soil. Zinc was accumulated in the corn stem to a higher extent on the unfertilized treatment with respect to corn stem exposed to other fertilizing treatments. Bearing in mind the fact that phosphorus fertilizers contain a different concentration of Cd, results have shown that the long-term application of the increasing doses of phosphorus has led to higher amounts of Cd in the soil and in corn as well, in the plots fertilized with 100 and 150 kg P2O5/ha. However, those values are far below the maximum permissible recommendation.
Optimization of design and operational parameters of a vibration-based seeding device for potato mini-tubers
Authors: Liu Wenzheng
Published: February 2022

The mechanized planting of potato mini-tubers is vital for the development of the potato industry in China. A vibration-based seeding device for mini-tubers was designed and tested. The objectives of this study were to describe the design process of the main components of the seeding device by theoretical analysis, evaluate the reliability of the key components of the seeding device by finite element analysis, assess the seeding device’s working performance, and obtain a better combination of operational parameters by bench tests. According to a theoretical analysis of the seeding device design, the eccentricity of the eccentric wheel (EEW), rotational speed of the drive shaft (RSDS) and linear speed of the conveyor belt (LSCB) were selected as critical factors influencing the seeding device’s working performance. A Box-Behnken design (BBD) was applied to conduct bench tests and build regression models. Based on the optimized results, verification experiments were performed by a bench tester. The results showed that the multiple-seeding index (MUSI) was 3.10%, the miss-seeding index (MISI) was 4.01%, and the qualified-seeding index (QSI) was 92.89% when the EEW, RSDS and LSCB were 4 mm, 821 rpm, and 86 mm s-1, respectively. Verification experiments showed that the results agreed well with the theoretical optimization values
Effects of structured education and a physical activity prescription during prenatal care on maternal and fetal outcomes: A quasi-experimental study
Authors: Saidi Latifa , Godbout Pierre D. , Morais-Savoie Camille , Bélanger Mathieu
Published: February 2022

Background: Physical activity (PA) during pregnancy is associated with healthy gestational weight gain (GWG) and a reduction in risk of developing gestational diabetes (GD), hypertension (GHT) and fetal macrosomia. However, less than 20% of pregnant women meet the PA recommendations in Canada. We tested the effects of PA education and a PA prescription by prenatal nurses and physicians on fetal and maternal outcomes.Methods: Administrative data from two periods with distinct prenatal care offering were used. In the first period, 394 pregnant women followed at the obstetrics clinic of a university hospital received standard care whereas 422 women followed in the second period received standard care supplemented with education on the relevance of PA during pregnancy and a prescription for PA. Logistic regressions were used to compare odds of excessive GWG, GD, GHT, and fetal macrosomia between the two study groups.Results: The addition of PA education and PA prescription to prenatal care was associated with a 29% reduction in odds of excessive GWG (adjusted OR 0.71, 95% CI 0.51-0.99), 73% reduction in odds of GHT (0.27, 0.14-0.53) and 44% reduction in odds of fetal macrosomia (0.56, 0.34-0.93). The intervention was not associated with different odds of GD (0.48, 0.12-1.94). Conclusions: The inclusion of education and prescription of PA as part of routine prenatal care can lead to significant improvements in maternal and fetal health outcomes.
Research Trends in Japanese Public Administration: Statistical Content Analyses of Article Titles in Public Administration Review Quarterly (1978–2019)
Authors: Moteki Yasutoshi
Published: February 2022

This paper quantitatively explains research trends in postwar administrative studies in Japan using statistical analyses of nearly 40 years of article titles from the Public Administration Review Quarterly, from its first (1978) to 165th issue (2019). Published quarterly by the Institute of Administrative Management, which is tied to the Ministry of Internal Affairs and Communications, this is a renowned journal in public administration in Japan. The co-occurrence network analysis and correspondence analysis revealed changes in research interests. There was substantially more research on administrative reforms through the postwar Showa and Heisei eras. The configuration figures of the correspondence analysis indicate that the first dimension concerns administrative reforms, the second concerns historical events/administrative systems, and the third concerns evaluations and Kaizen. The co-occurrence network analysis showed that studies during the Showa era (1978–1988) could be partly characterized by two extracted compound words: the United States and the United Kingdom. In other words, public administration in Japan in this period was strongly influenced by Western public administration. Japan became a feature of studies of public administration during the Heisei era (1989–2018). These features are consistent with those found in previous quantitative studies.

Early reanalyses are less than optimal for investigating the regional effects of ozone depletion on Southern Hemisphere (SH) high-latitude climate because the availability of satellite sounder data from 1979 significantly improved their accuracy in data sparse regions, leading to a coincident inhomogeneity. To determine whether current reanalyses are better at SH high-latitudes in the pre-satellite era, here we examine the capabilities of the European Centre for Medium-range Weather Forecasts (ECMWF) fifth generation reanalysis (ERA5), the Twentieth Century Reanalysis version 3 (20CRv3), and the Japanese Meteorological Agency (JMA) 55-year reanalysis (JRA-55) to reproduce and help explain the pronounced change in the relationship between the Southern Annular Mode (SAM) and Antarctic near-surface air temperatures (SAT) between 1950–1979 (EARLY period) and 1980–2020 (LATE period). We find that ERA5 best reproduces Antarctic SAT in the EARLY period and is also the most homogeneous reanalysis across the EARLY and LATE periods. ERA5 and 20CRv3 provide a good representation of SAM in both periods with JRA-55 only similarly skilful in the LATE period. Nevertheless, all three reanalyses show the marked change in Antarctic SAM-SAT relationships between the two periods. In particular, ERA5 and 20CRv3 demonstrate the observed switch in the sign of the SAM-SAT relationship in the Antarctic Peninsula: analysis of changes in SAM structure and associated meridional wind anomalies reveal that in these reanalyses positive SAM is linked to cold southerly winds during the EARLY period and warm northerly winds in the LATE period, thus providing a simple explanation for the regional SAM-SAT relationship reversal.

Purpose–Tuberculous cervical lymphdaenopathy is the most common manifestation of extrapulmonary tuberculosis and frequently present imaging diagnostic dilemma with metastatic lymphadenopathy. Ours is observational study done to evaluate the role of sonography including Doppler and strain elastography in tubercular cervical lymphadenopathy.Methods-100 fine needle aspiration cytology/histopathological examination(FNAC/HPE) proven tubercular lymph nodes were evaluated with sonography and strain elastography Features evaluated with sonography are location, size, short/long axis diameter(S/L) ratio, presence or absence of echogenic hilum ,intra-nodal necrosis, intra-nodal calcification associated soft tissue features like periadenitis or collection and pattern of vascularity. With strain elastography(USE) color coded elastograms and strain ratio were evaluated. Results-On evaluation tubercular nodes are large size, S/L ratio >0.5, show intra-nodal necrosis and peripheral vascular pattern. 91% tuberculous lymph nodes had color coded elastograms>2 pattern which is similar to malignant lymph nodes and 99% of tuberculous lymph nodes show strain ratio< 1.99.Conclusion - Grey scale and Doppler assessment of tubercular lymph nodes reveals findings similar to that encountered in metastatic nodes, hence differentiation difficult .While strain ratio being semi-quantitative is more objective criteria of assessment compared to color coded elastograms. Hence adding semi-quantitative elastographic evaluation with US will help in further characterization of tuberculous nodes.

Purpose: Bulimia nervosa (BN) and anorexia nervosa (AN) are potentially life-threatening eating disorders (ED) that primarily affect young people, mostly women. The central common pathology is linked to the relationship with food and with abnormalities in food intake.A previous study indicated that individuals with ANtend to overestimate food portion sizes compared to healthy controls (HC), but no study has investigated these patterns in BN, which was the objective of this study.Methods: Women with BN (27), AN (28), and HC (27) were asked to rate different meal portion sizes in two conditions: as if they were supposed to eat them (intent-to-eat condition) or in general (general condition). BN results were compared to HC and AN using mixed model analyses.Results: BN showed larger estimations compared to HC, while smaller estimations compared to AN. These differences were found mostly for intermediate portion sizes. No difference for conditions (intent-to-eat; general) was found between groups.Conclusion: When estimating food portion sizes, individuals with BN seem to fall intermediately between HC and AN. ED symptoms in BN were most strongly associated with higher portion estimation. This might therefore reflect one aspect of the cognitive distortions typically seen also in AN.A therapeutic option could include the frequent visual exposure to increasing portions of food, what may serve to recalibrate visual perceptions of what a “normal-sized” portion of food looks like.Level of evidenceLevel II: Evidence obtained from well-designed controlled trials without randomization.

Colloidal lead halide perovskite (LHP) nanocrystals (NCs, with bright and spectrally narrow photoluminescence (PL) tunable over the entire visible spectral range, are the latest generation of semiconductor quantum dots (QDs) of immense interest as classical and quantum light sources. LHP NCs form by sub-second fast and hence hard-to-control ionic metathesis reactions, which severely limits the access to size-uniform and shape-regular NCs in the sub-10 nm range. We posit that a synthesis path comprising an intricate equilibrium between the precursor (PbBr2) and the Cs[PbBr3] solute for the QD nucleation may circumvent this challenge. Here, we report a room-temperature synthesis of monodisperse, isolable spheroidal CsPbBr3 QDs, size-tunable in the 3-13 nm range. The kinetics of both nucleation and therefrom temporally separated growth are drastically slowed down by the formation of transient Cs[PbBr3], resulting in total reaction times of up to 30 minutes. The methodology is then extended to FAPbBr3 (FA = formamidinium) and MAPbBr3 (MA = methylammonium), allowing for thorough experimental comparison and modeling of their physical properties under intermediate quantum confinement. In particular, QDs of all these compositions exhibit up to four excitonic transitions in their linear absorption spectra and we demonstrate that the size-dependent confinement energy for all transitions is independent of the A-site cation.

Background
The hippocampus, as one of the most critical regions of the brain, is significantly affected by exercise. The primary purpose of this study is to evaluate the effect of six weeks of high-intensity interval training (HIIT) and inhibition of calcitonin gene-related peptide (CGRP) on gene expression of vascular endothelial growth factor (VEGF) and serine/threonine type 2 kinase protein (mTORC2) in hippocampal tissue of male Wistar rats.
Methods
Thirty-two healthy male Wistar rats (8 weeks of age) were randomly assigned to one of four groups: control, CGRP inhibition, HIIT+CGRP inhibition, or HIIT. The CGRP inhibition group received 0.25 mg/kg/day of antibody intraperitoneally. The animals in the training groups underwent high-intensity interval training (HIIT, ten 2-minute work bouts per day at 22 m/min interspersed by 2-minute rest periods, five days/week). Real-time PCR (2-ΔΔCT) and one-way ANOVA were employed to measure the expression of genes and analyze the data, respectively.
Results
HIIT significantly enhanced VEGF (p≤0.002) and mTORC2 (p≤0.006) gene expression in the hippocampal tissue compared to the control group. HIIT+CGRP inhibition resulted in a substantial increase in VEGF expression compared to the control group (p≤0.007). While HIIT+CGRP inhibition significantly lowered mTORC2 gene expression (p≤0.001), HIIT alone did not (p≤0.001).
Conclusions
HIIT-induced physiological alterations in the hippocampus can improve the brain’s functional status via upregulation of VEGF and mTORC2 gene expression as an effective non-pharmacological method. Additionally, HIIT+CGRP inhibition may represent a new approach via the VEGF and mTORC2 pathways in the hippocampus.

Sediments act as a sink or source of pollution under various conditions. Moreover, they can serve as pollution indicators. The present research aims to evaluate sediment quality associated with its content in heavy metals and the potential ecological risk, focusing on the sub-branches of Nile River (Rayahs) in Egypt, including El-Tawfiky (RT), El-Menoufy (RM), El-Behary (RB), and El-Nassery (RN). According to the results, El-Rayahs sediments are characterized by an increasing sand fraction, followed by mud. Regarding metals pollution, Cd registered the highest pollution ranking, whereas Fe, Mn, Zn, Pb, and Ni exhibited the lowest effect. Furthermore, the ecological risk for El-Rayahs sediments increases northward; however, most sites either showed slight pollution or did not record any degree of contamination, except the northern stretch of El-Behery (El-Mahmoudia Canal), which is a very high-polluted zone, with high ecological risk according to the contamination degree (Cd) and potential ecological risk (RI) indices.
