Abstract: Phytoplanktons which are present in a variety of aquatic habitats were studied with respect to their species diversity and distribution, studies on phytoplankton and water quality of Hadinaru lake , Nanjanagudu, Mysore, Karnataka were undertaken for 5 months of 2022 (April 2022 to August 2022). . The water samples were analyzed to physical and chemical parameters by following the standard methods of APHA (2005) and Trivedi and Goel (1984). The quantitative analysis of phytoplankton was done by Lackey’s drop method modified by saxena (1987). Diversity indices have been discussed by using PASTA Software Program. Among the total 52 species recorded during the study, 25 were from Bacillariophyceae, 8 from Chlorophyceae, 8 from Cyanophyceae. 4 from Desmidiaceae 3 from Euglenophyceae and 2 from Charophyta. Bacillariophyceae was the most dominant group followed by Chlorophyceae, Cyanophyceae, Desmidiaceae. Euglenophyceae and Charophyta. The result of physico- chemical and biological parameters along with statistical method and biodiversity indices indicated that the Hadinaru lake is threatened ecologically due to various anthropogenic activities which lead organic pollution and eutrophication status of the lake. Statistical program Bray – Curtis similarity index explained, the cluster of EC, Total hardness and Total alkalinity is highly correlated with the clusters of phytoplanktons. Shannon and Weiner index showed that the lake was heavily polluted in the month of April due to increased temperature.

This study investigates the English grammar learning strategy used among high, middle, and low achievers’ students in Indonesia. The aim is to reveal which types of strategies that high, middle, and low achievers’ students applied most while learning English grammar and to check whether or not there is difference grammar learning strategy used by high, middle, and low achievers’ students. A lot of researchers have concentrated their interest on the grammar learning strategy area, including in Indonesia, however, it was not seen much or still found limited references to check the grammar learning strategy among high, middle, and low achievers’ students. Besides, the grammar learning strategy instruments of other Indonesian researchers are complexly varied. This study is focused on finding the strategies that high, middle, and low achievers’ students used through Pawlak’s Grammar Learning Strategy Inventory or GLSI (2018) with 100 participants (high vs middle vs low achievers’ students) involved. The results showed that there are significant differences between the frequent use of grammar learning strategies between low, middle, and high achievers' students. Social strategies are the most frequently used grammar learning strategies by low and middle achievers’ students, while metacognitive strategies are the strategies most frequently used by high-achieving students in Indonesia.

Reading the Precariat Characters in the Fiction: Focusing on “Hana's Breath” by Jo Hae-jin
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Hong Inyoung
Published: December 2022

Objectives The purpose of this paper is to analyze the characteristics of the character as a precariat, focusing on the unstable labor character in Cho Hae-jin's “Hana's Breath” (2019), and to derive the educational implications of reading a fiction based on the response of a college student reader.
Methods The framework of the analysis of the character as a precariat in “Hana's Breath” is two perspectives, one is a political and sociological perspective that sees precariat as a ‘a-class-in-the-making’, and the other is an existential perspective that all human beings have no choice but to have precariousness, that is, vulnerability. The category of analyzing the characters in the fiction is, first, the description of the reality and situation in which precariat is placed as a new class, second, anxiety and alienation in the process of interacting with others as precariat, and third, existential vulnerability. The analysis of the reader's response was based on the precariat theory, and reflected the characteristics found inductively after repeatedly reading the critical essay.
Results The fiction describes the social reality in which precariat appears, describes the feelings of anxiety and alienation caused by labor instability, and depicts human existential weakness beyond precarity at the political and social level. In response, the reader strongly recognized the class situation of the character as a social problem and expressed a critical consciousness about it. In addition, the reader felt an ethical consciousness to improve the current situation while sympathizing with anxiety and fear due to the persecution of the characters in the story, and expressed compassion for the inherent vulnerability of humans.
Conclusions While reading fiction centering on the precariat characters, the reader can have a deeper understanding of the character's social context, recognize the responsibility as a community member, and acquire universal empathy.

Published: December 2022

Objectives This study investigated the perception of early childhood teachers’ teaching media through metaphor analysis. Through this study, it is intended to present the direction of the selection and use of teaching media for high-quality curriculum operation.
Methods This study used a metaphor analysis method. The metaphor analysis method is to examine the metaphor expression and the reason for metaphor together through a semi-structured sentence completion questionnaire. To this end, a metaphor analysis survey was conducted on 180 early childhood teachers. The questionnaire was composed of the sentence “Teaching media of the 2019 revised Nuri curriculum is ( ). Because, ( ).” The collected data were analyzed according to the metaphor analysis procedure to categorize the types of metaphors.
Results The research results were divided into ‘perception of teaching media from children’ perspective’ and ‘perception of teaching media from teachers’ perspective’. First, perception of teaching media of early childhood teachers from the perspective of children were found to be ‘something that children can manipulate and touch directly’, ‘what changes according to childrne’ thoughts’, ‘encouraging voluntary participation of children’, ‘growing children’. Second, perception of teaching media of early childhood teachers from the perspective of teacher were found to be ‘giving directions to play support’, ‘reflecting the professionalism of the teacher’, ‘making the revised nuri curriculum run efficiently’, ‘everything around children’ life’.
Conclusions These results suggest that the selection and use of teaching media should be centered on children, and that efforts should be made to develop teachers’ professional perspectives on teaching media.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Jeong Hyang-Jin
Published: December 2022

Objectives The purpose of this study is to identify the mediating effect of the self-esteem between appearance satisfaction and job-seeking anxiety, and between appearance satisfaction and career preparation among nursing students.
Methods A cross-sectional study was performed to 255 senior nursing students with off-line survey. The data were analyzed by frequency, t-tests, ANOVA, Pearson’s correlation coefficient, multiple regression on analysis using SPSS 23.0 software. To analyze the mediating effect, a 3-step regression by Baron and Kenny (1896) was conducted. Sobel test was conducted to verify the significance of the mediating effect for self-esteem.
Results This study showed that self-esteem was significantly correlated with appearance satisfaction(r=.60, p<.001), the job-seeking anxiety(r=-.32, p<.001), and career preparation behavior(r=.23, p<.001). The self-esteem had significant partial mediating effect between appearance satisfaction and job-seeking anxiety(z=-3.09, p=.002). And the self-esteem had significantly full mediating effect between appearance satisfaction and career preparation behavior(z=-2.84, p=.005).
Conclusions Therefore, it is important to improve the self-esteem of nursing students, in order to reduce job-seeking anxiety and to increase career preparation behavior in relation to appearance satisfaction. Furthermore, various intervention strategies are needed to improve the self-esteem of nursing students with negative perceptions of their appearance, or low self-esteem.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Lee YuRee
Published: December 2022

Objectives In this study, the university's teaching and learning outcomes are viewed as competency improvement and major class satisfaction. Since these are influenced by students' active class-related activities, this study compared the influence of students' active class-related activities and analyzed the relationship.
Methods To this end, the relationship between class-related activities derived as outcomes was analyzed with a structural equation model for blended learning students at a University in Busan, a non-metropolitan area. Pre-class activities, team-based teaching methods, and active learning participation were set as class-related activities, and competency improvement and major class satisfaction were set as teaching and learning outcomes.
Results In the analysis results, the direct effect of challenging learning activities on competency improvement was greater than that of active learning activities. The positive influence on major class satisfaction was the largest in the total effect of challenging learning activities, followed by the direct effect of class preparation, the direct effect of challenging learning experiences, and the indirect effect of challenging learning activities that mediated competency improvement.
Conclusions Based on the results, it is necessary to consider class design capable of class preparation and expand experience in active learning activities, challenging learning activities, and cooperative learning activities to induce competency improvement through meaningful educational experience in blended learning.
Las intervenciones en el Palacio de La Moneda de los siglos XIX, XX y XXI. Los proyectos y sus arquitectos
Authors: Suhrcke-Caballero Gunther , Gondeck-Cepeda Katherine
Published: December 2022

The Palacio de La Moneda, or La Moneda Palace, is the seat of the Presidency and the Executive Power of Chile, the Ministry of the Interior and Public Security, the General Secretariat of the Presidency, and the General Secretariat of the Government. It is one of the main historical and most important buildings in Chile in terms of its current representative function, as the Government Palace. Since its construction, in 1786, it has been the witness and star of the historical-political and social-urban evolution of the nation, of events that have been expressed in its own architectural metamorphosis and the evolution of the urban fabric. Designed by architect Joaquín Toesca, a disciple of Francesco Sabatini, a professional of the court of Carlos III, King of Spain (1759-1788), the Palace is the main example of Neoclassicism in Chile. It was inaugurated in 1805 as the Royal Mint of Santiago, to mint the kingdom's currency. After the independence of Chile, in 1845, the Seat of Government and Presidential Residence moved to the building. It is on this date that it adopts its representative function, and therefore, the moment where the first important modification of its floorplan took place, beginning a process of continuous evolution characterized by the dynamic transformation and permanent adaptation of its architecture, through successive interventions, functional updates, and its reconstruction after the 1973 air raid. The lack of an organized and detailed record of its permanent alterations makes it difficult to understand them from their current state and for possible future interventions. As a result, this article presents the most important and significant changes on the perception of the building, thus becoming the first organized record of contemporary interventions of La Moneda Palace.
Historic timber buildings restored for public purposes in Southern Chile. A critical analysis and an approach to a cultural landscape
Authors: Saelzer-Canouet Gerardo , Campusano-Brown David , Gómez-Alvial Pablo
Published: December 2022

The objective of this paper is to update and summarize the arguments behind the Integrated Heritage Rehabilitation (IHR) for Wooden Cities methodology. Building in the Coastal Temperate Rainforest ecoregion relied on native species, and is still characteristic of the towns in southern Chile, including the city of Valdivia. However, the historic town’s urban fabric is vulnerable to natural disasters and neoliberal market practices. Regulations and instruments for architectural restoration hinder IHR since their primary focus lies in social sciences, excluding the fundamental architectonic technical aspects, as well as a broader understanding of the context. Through an analysis of a set of historic buildings restored with public funds, the relationship between social sciences, engineering, architecture, and the theories of public use and landscape is patent. It is evident that there is a need to establish effective practices to extend the service life of buildings through cultural heritage management. Eight key points were identified, that connect history with the material conditions, which today are lacking in the Chilean Public Service. For the restoration processes to be integrated, evaluations must include new dimensions, such as the economic relationship and the material or tangible management, as well as the integration with the surrounding original architectural identity and the ease with which it can be culturally associated. From the harmonization of these eight points within the heritage regulatory framework, an improvement of the integrated rehabilitation of heritage buildings in the southern Chilean towns is expected, with priority given to timber conservation and public contribution.

Authors: Ramírez Alarcón M. Meredit , Murrieta Galindo Rene , Hernández Orduña M. Graciela , Bolívar Cimé Beatriz
Published: December 2022

Las abejas y otros polinizadores se enfrentan a una grave amenaza de supervivencia debido a una serie de factores de alcance regional y mundial. Para diseñar estrategias de conservación exitosas, es necesario evaluar el interés de las personas y el nivel de apoyo a la apicultura. Nuestro objetivo fue analizar la percepción de la sociedad sobre la apicultura en una franja de cinco municipios de la zona centro de Veracruz, México. Se emplearon encuestas semiestructuradas con un muestreo aleatorio en cada uno de los municipios con actividad apícola. Los datos cualitativos se analizaron empleando un análisis de contenido contrastivo codificado, y los cuantitativos con estadística inferencial. Se encuestó a un total de 282 personas, de las cuales se encontró que el 89% tiene una percepción positiva de la apicultura, debido a los beneficios para la salud del consumo de miel y los efectos ambientales positivos de la polinización. Sin embargo, el nivel de sus expectativas, interés, experiencia, actitudes y sentimientos no era muy alto, ni sus tendencias de comportamiento eran conducentes a la conservación. El 52% de los encuestados veía la apicultura como “algo” vagamente relacionado con el medio ambiente, el 48% la relacionaba con la salud, el 43% con la nutrición, el 39% con la cultura, el 37% con la economía y el 20% con la educación. Las personas entre 19 y 25 años de edad de los municipios de Xico y Coatepec mostraron el mayor interés por la apicultura. Concluimos que una estrategia de concientización es indispensable para la preservación de la actividad, enfatizando el papel clave de la apicultura en la conservación del medio ambiente y los beneficios sociales tangibles que ofrece.

Published: December 2022

In plants, neither the contribution of the plasmotype in controlling
circadian clock plasticity and overall plant robustness, nor what may be
the fitness consequences of clock plasticity on genetic make-up has been
fully elucidated. Here, we investigated the cytonuclear genetics
underlying thermal plasticity of clock rhythmicity and fitness traits in
reciprocal doubled haploid population and a diversity panel of wild
barley ( Hordeum vulgare ssp. spontaneum). We identified a
positive correlation between the thermal plasticity of clock and
vegetative growth with the robustness of reproductive output. Moreover,
we identified significant linkage disequilibrium and epistatic
interactions between previously identified drivers of clock (DOC) loci
and the chloroplastic RpoC1 genes, indicating adaptive value for
specific cytonuclear gene combinations. Finally, heterologous
over-expression of two barley RpoC1 alleles in Arabidopsis
showed significantly differential plasticity under elevated
temperatures. Our results unravel previously unknown cytonuclear
interactions as well as specific alleles within the chloroplastic genome
that control clock thermal plasticity while also having pleiotropic
effects on plant fitness in the field. The evolutionary and functional
relationship between nuclear and chloroplastic DOCs suggest that
adaptation to warming environments involve cytonuclear changes to confer
local adaptation.

The Oral Healthcare community, including clinical professionals and industry, acknowledges the shared responsibility to deliver products and interventions that improve oral health in a more sustainable manner. To deliver this, the community is working in alignment with the UN Sustainable Development Goals. Key to establishing this collaborative stakeholder consensus is a deep contextual understanding of the challenge. This is achieved through a comprehensive account of the levels of awareness of the environmental impacts, the challenges to resolve these impacts together with the drivers and opportunities to promote sustainable practices. This report concludes with a strategic action framework that makes specific recommendations and identifies best practice to achieve these goals. The promotion of excellent oral healthcare and the development of a circular economy are core to this strategy. Additionally, it is also important to recognise the opportunities to collaborate across the sector, and throughout supply chains, to develop and promote sustainable practices to achieve meaningful and measurable environmental outcomes in the sector. In this context, the FDI World Dental Federation convened the development of this volume, Consensus on Environmentally Sustainable Oral Healthcare: A Joint Stakeholder Statement. This consensus statement brings together a global coalition of stakeholders, representing all aspects of industry, health professionals, experts, legislative authorities and governments. The statement uses a truly collaborative, multi-stakeholder approach to identify the major challenges facing oral healthcare, the complex drivers that underpin current behaviours and practices, and the best opportunities to improve and deliver sustainable oral healthcare for people and the planet. Concluding with an impactful and robust strategic action plan that crosses all boundaries, the statement identifies a series of actions and recommendations for best practice that address the sustainability issues facing the whole sector. Written by The University of Sheffield colleagues Prof Nicolas Martin, Dr Steven Mulligan, Hon. Prof Ian J Shellard and Prof Paul V Hatton, Consensus on Environmentally Sustainable Oral Healthcare: A Joint Stakeholder Statement is the result of a collaborative working partnership between the FDI-Sustainability in Dentistry Task Team and the project founding partners (Colgate-Palmolive, Dentsply Sirona, Haleon, Procter & Gamble and TePe) with the wide participation of stakeholders throughout the oral healthcare supply chain.

Abstract 

OBJECTIVE 

The relationship between diabetic ketoacidosis (DKA) at diagnosis of type 1 diabetes and long-term glycemic control varies between studies. We aimed firstly to characterise the association of DKA and its severity with long-term HbA1c in a large contemporary cohort, and secondly to identify other independent determinants of long-term HbA1c. 

RESEARCH DESIGN AND METHODS 

Participants were 7961 children and young adults diagnosed with type 1 diabetes by age 30 years from 2000-2019 and followed prospectively in the Australasian Diabetes Data Network (ADDN) until 31/12/2020. Linear mixed effect models related variables to HbA1c. 

RESULTS 

DKA at diagnosis was present in 2647 (33.2%) participants. Over a median 5.6 (IQR 3.2,9.4) years follow-up, participants with severe, but not moderate or mild, DKA at diagnosis had a higher mean HbA1c (+0.23%, 95% CI:0.11,0.28; [+2.5mmol/mol, 95% CI:1.4,3.6]; p<0.001) compared to those without DKA. Use of continuous subcutaneous insulin infusion (CSII) was independently associated with a lower HbA1c (-0.28%, 95% CI:-0.31,-0.25; [-3.1mmol/mol, 95% CI:-3.4,-2.8]; p<0.001) than multiple daily injections, and CSII use interacted with severe DKA to lower predicted HbA1c. Indigenous status was associated with higher HbA1c (+1.37%, 95% CI:1.15,1.59; [+15.0mmol/mol, 95% CI:12.6,17.4]; p<0.001), as was residing in postcodes of lower socioeconomic status (most versus least disadvantaged quintile +0.43%, 95% CI:0.34,0.52; [+4.7mmol/mol, 95% CI:3.4,5.6]; p<0.001). 

CONCLUSIONS 

Severe, but not mild or moderate, DKA at diagnosis was associated with a marginally higher HbA1c over time, an effect which was modified by use of CSII. Indigenous status and lower socioeconomic status were independently associated with higher long-term HbA1c.
Superextension, Modal Assertability, and Hypothetical Discernibility:
Authors: Vollet Lucas Ribeiro
Published: December 2022

We argue that Russell’s treatment of propositions containing non-existent denotations is the prelude of a strategy for discerning the predictive content of any proposition with descriptions (and incomplete symbols), insofar as its indeterminacy is classifiable as a possible extension. We argue, further, that Russell’s theory of propositional functions is dedicated to explaining the discernibility of hypothetical propositions, through representing (what we call) the superextension of assertoric modal propositions. The indeterminacy of the truth of hypothetical propositions is thus paired with a second- order classification condition, expressing its conjectural content as the projected scope of instantiation of a propositional function; which in turn is the superextension of a modal predicate. Russell’s theory is his non-pragmatic answer to the problem of assertability in unstable and uncertain conditions. It involves a sophisticated thesis about the discernibility of complex contents, such as those represented by analogical and approximate denotations (descriptions, fictions, etc.), which classify more than one possibility of instantiation in different modal and intensional contexts. We will conclude this article by testing the assumption that Russell’s theory favors a coherentist theory, seeing that as it admits assertability conditions that are super-mapped in a system, or that derive from different orders of referential layers.
Dewey e Simondon
Authors: Cabral Caio César
Published: December 2022

Nosso objetivo, no presente artigo, é propor uma articulação entre a teoria da individuação de Gilbert Simondon e a teoria da investigação de John Dewey. Em relação à primeira, serão enfatizados os aspectos “biológico” e “psíquico” de individuação; quanto à segunda, ressaltaremos seus principais elementos naturalistas e epistemológicos, assim como os conceitos mais gerais de “experiência” e de “natureza” de Dewey. Defenderemos que o processo de individuação tem estreita relação com a capacidade, possuída por todo indivíduo vivo, de solucionar problemas ou situações de conflito resultantes de sua constante interação com o ambiente. Proporemos, mais precisamente, uma conexão teórica entre o princípio ou conceito de individuação e a ideia de que existe no  organismo vivente uma aptidão investigativa que não apenas restaura seu equilíbrio “metaestável”, como também, e ao mesmo tempo, lhe proporciona sempre uma nova individualidade, tanto biológica como psíquica. Esperamos obter, como resultado deste processo de síntese envolvendo as ideias de Simondon e de Dewey, uma compreensão ampliada das respectivas teorias da individuação e da investigação.

The accuracy of water flow rate measurement with an ultrasonic flow meter (UFM) is affected by pipeline conditions. On water pipelines, there is often no the required length of direct section, required by the device passport or regulatory documents. Therefore, we conducted experiments using UFM to measure water flow rate in the zone of influence of non-direct sections of the water pipeline. The flow rate was measured in two planes of the pipeline with an offset of 90 o and the average value was taken. Thus, it was expected to take into account the average water velocity for the asymmetric velocity profile. The results of water flow rate measuring with UFM on short direct sections of the water pipeline, limited by pipeline bends sudden constriction of the pipeline, are presented. The greatest influence on the UFM measurement error is the 90 o pipeline bends.
OPTIMIZATION OF DEPLOYMENT PERIODS OF NON-RHYTHMIC FLOW-LINES BY COMPLEX MECHANIZED MACHINES

The article proposes to balance processes with non-rhythmic flow-lines according to the period of work execution with the use of complex mechanized machines (CMM). An increase in the period of deployment in the flow-line and downtime of non-critical works calculated by the Critical Path Method requires the development of optimization methods to reduce the construction period. We proposed a hypothesis to equalize work rhythms due to the redistribution of work volumes on interdependent divisions (ID) between CMMs. A typical matrix model is used to compare the period of work execution. The calculation formulas are given for determining the execution time on the ID, the deployment period of the flow-line, the brigade, and the building. There is a new method of optimizing the flow-line deployment period with the parallel use of complex mechanized machines proposed in the article. This method shortens the construction period.
Management of Infantile Epilepsies

Objectives. Uncontrolled seizures in children 1 to 36 months old have serious short-term health risks and may be associated with substantial developmental, behavioral, and psychological impairments. We evaluated the effectiveness, comparative effectiveness, and harms of pharmacologic, dietary, surgical, neuromodulation, and gene therapy treatments for infantile epilepsies. Data sources. We searched Embase®, MEDLINE®, PubMed®, the Cochrane Library, and gray literature for studies published from January 1, 1999, to August 19, 2021. Review methods. Using standard Evidence-based Practice Center methods, we refined the scope and applied a priori inclusion criteria to the >10,000 articles identified. We ordered full text of any pediatric epilepsy articles to determine if they reported any data on those age 1 month to <36 months. We extracted key information from each included study, rated risk of bias, and rated the strength of evidence. We summarized the studies and outcomes narratively. Results. Forty-one studies (44 articles) met inclusion criteria. For pharmacotherapy, levetiracetam may cause seizure freedom in some patients (strength of evidence [SOE]: low), but data on other medications (topiramate, lamotrigine, phenytoin, vigabatrin, rufinamide, stiripentol) were insufficient to permit conclusions. Both ketogenic diet and the modified Atkins diet may reduce seizure frequency (SOE: low for both). In addition, the ketogenic diet may cause seizure freedom in some infants (SOE: low) and may be more likely than the modified Atkins diet to reduce seizure frequency (SOE: low). Both hemispherectomy/hemispherotomy and non-hemispheric surgical procedures may cause seizure freedom in some infants (SOE: low for both), but the precise proportion is too variable to estimate. For three medications (levetiracetam, topiramate, and lamotrigine), adverse effects may rarely be severe enough to warrant discontinuation (SOE: low). For topiramate, non-severe adverse effects include loss of appetite and upper respiratory tract infection (SOE: moderate). Harms of diets were sparsely reported. For surgical interventions, surgical mortality is rare for functional hemispherectomy/hemispherotomy and non-hemispheric procedures (SOE: low), but evidence was insufficient to permit quantitative estimates of mortality or morbidity risk. Hydrocephalus requiring shunt placement after multilobar, lobar, or focal resection is uncommon (SOE: low). No studies assessed neuromodulation or gene therapy. Conclusions. Levetiracetam, ketogenic diet, modified Atkins diet, and surgery all appear to be effective for some infants. However, the strength of the evidence is low for all of these modalities due to lack of control groups, low patient enrollment, and inconsistent reporting. Future studies should compare different pharmacologic treatments and compare pharmacotherapy with dietary therapy. Critical outcomes underrepresented in the literature include quality of life, sleep outcomes, and long-term development.
