Construction of self as a principal: Meanings gleaned from narratives of novice school principals
Authors: Blose Sibonelo , Mkhize Bongani Nhlanhla , Ngidi Sihle Siyabonga , Myende Phumlani Erasmus
Published: December 2022

It is assumed that individuals’ cognitions of who they are in a particular social structure influence their behaviour in that space. Likewise, school principals’ cognition of who they are in schools as social structures influences how they behave as leaders. In this article, we use the role identity theory as a framework to analyse novice principals’ narratives of lived experiences to understand how they construct themselves as principals in schools and how these constructions influence their execution of leadership. Positioned within the interpretivist paradigm, we adopted the narrative inquiry methodology to engage with the lived experiences of 3 purposively selected novice principals from the Pinetown district in KwaZulu-Natal. The narrative interview was employed to generate field texts, which were subsequently analysed using 2 methods: narrative analysis and analysis of narratives. From our analysis of field texts, 4 themes explaining how the participating novice principals construct themselves as school principals were identified; these themes are: a leader as a learner, re-establishing oneself as a leader, spanning boundaries, and leading to inspire. From these themes, we conclude that a principal’s conception of self is dynamic and is a blend of multiple meanings generated prior to becoming a principal and meanings generated during the principalship tenure.

Published: December 2022

In the study reported on here we investigated the use of post-method practice to optimise pre-service teachers’ teaching practice and English First Additional Language (EFAL) proficiency. This study was premised on the theoretical framework of Paulo Freire’s critical pedagogy which promotes diverse perspectives in language learning and teaching among teachers and learners. Qualitative data were collected using semi-structured interviews with 10 (n = 10) third year pre-service teachers enrolled in a 4-year Bachelor of Education (BEd) degree programme in the Department of Language Education, School of Education at the University of Limpopo, South Africa. We found that post-method pedagogy enables pre-service teachers to monitor their teaching process and optimise learners’ potential to learn, which affords them opportunities for critical reflection on the self and the social world, as well as opportunities to form learning communities. The results suggest that post-method pedagogy enables pre-service teachers to recognise their prior and current knowledge, and their potential to teach and act autonomously. This promotes their ability to know how to develop a reflective critical approach in their teaching by analysing and evaluating their teaching acts, initiating change in their classroom practices, and monitoring the effects of these changes. We concluded that post-method practice could provide teachers, curriculum developers and researchers with an understanding of the realisation of post method in teaching and learning of EFAL in South African classrooms.
The perspective of school leadership and management: The role of the school principal in academic learner performance
Authors: Memela Godfrey Khululekani Sihle , Ramrathan Labby
Published: December 2022

In this article we explore the perspectives of school leadership and management on the principal’s role in learners’ academic performance. School leadership and learner performance continue to be of great concern in the South African education system. We explore the relationship between school leadership and learner performance from a school leadership and management perspective. Since the attainment of democracy, the South African education landscape has been plagued by poor learner performance. While the reasons are as diverse as the nation itself, the adverse effects of poor learner performance on the school system or the quality of education cannot be overemphasised. As a result, we explored school leadership and learner performance as it relates to the leadership of secondary school principals. Principals’ lived stories provided the empirical evidence for this article. The findings reveal that a principal’s leadership plays an important role in school management and learner performance.

Published: December 2022

Resumo O objetivo neste estudo foi avaliar o efeito da direção da corrente elétrica na resistência da união resina composta-dentina usando três sistemas adesivos. Dentes molares humanos foram distribuídos de acordo com o sistema adesivo (dois passos autocondicionante - Clearfil SE Bond, Kuraray [CSE]; e um passo autocondicionante - Single Bond Universal, 3M ESPE [SBU]; e dois passos convencional - Adper Single Bond 2, 3M ESPE [SB2]), a direção da corrente elétrica (sem corrente elétrica - controle, correntes elétricas direta e reversa - 35µA) e tempo de armazenamento (24h - imediato e 6 meses). Blocos de resina composta (Filtek Z350XT, 3M ESPE) foram aderidos à dentina. Amostras de dentina-resina foram produzidas e armazenadas em água destilada a 37ºC por 24 horas e 6 meses para o teste de resistência da união à microtração (µTBS) (n = 10; ~12 palitos por dente). Os padrões de fratura foram analisados em estereomicroscópio e classificados em falhas coesiva na dentina, coesiva na resina, adesiva ou mista. A penetração do adesivo na dentina e a formação da camada híbrida foram avaliadas em microscópio eletrônico de varredura (MEV). Os dados foram submetidos à ANOVA três fatores seguidos pelo teste post hoc de Tukey (α = 0,05). Não houve diferenças na µTBS quando os sistemas adesivos foram aplicados sob as correntes elétricas direta e reversa, mas ambas as correntes elétricas aumentaram a µTBS para todos os sistemas adesivos. SBU apresentou os menores valores de µTBS para o grupo controle em ambos os tempos de armazenamento e para a corrente elétrica direta em 6 meses de armazenamento. Falhas adesivas foram mais frequente em todos os grupos. A corrente elétrica formou longos tags resinosos para todos os sistemas adesivos. O armazenamento por 6 meses não diminuiu significativamente os valores de µTBS. Ambos os sentidos da corrente elétrica (cargas positivas e negativas) a 35µA podem aumentar a µTBS dos sistemas adesivos testados à dentina.

Efficiency of trap nests in attracting stingless bees in the central Brazilian Amazon
Authors: CRUZ Iris Andrade da , NUNES-SILVA Carlos Gustavo , CARVALHO-ZILSE Gislene Almeida
Published: December 2022

ABSTRACT Obtaining colonies of stingless bees in the wild for the formation or expansion of meliponaries and other purposes is permitted by law in Brazil using bait containers or trap nests, and other non-destructive methods. We tested the efficiency of trap nests made from plastic bottles for attraction and nesting of stingless bees in the central Brazilian Amazon. We used 2-L and 5-L bottles and three types of attractants (cerumen and geopropolis from Melipona seminigra, M. interrupta and a mix of the two). We used 216 trap nests distributed in three experimental areas during 13 months. Visitation by six species of stingless bees in 58 (26.9%) trap nests, and nesting by three species in 12 (5.6%) trap nests in two areas near meliponaries was recorded. There was no significant difference between trap-nest size, nor among attractants for visitation or nesting, suggesting that the availability of cavities or hollows is more important than odor for nesting. Monthly pooled visitation and nesting events were not correlated with monthly rainfall. Based on our results, we can conclude that, despite the low capture rate, the acquisition of swarms through nest traps is a viable alternative to obtain new colonies of stingless bees for meliponaries.
First record of Psocodea (Psocoptera) on coffee (Coffea canephora) in the Brazilian Amazon (Rondônia state)

Published: December 2022

ABSTRACT There is much information regarding the association of Psocoptera and coffee as stored grain pests and little is known about their presence in coffee plants. We conducted a survey in a coffee plantation of Coffea canephora in the municipality of Candeias do Jamari, Rondônia state, Brazil, where we obtained the first record of a coffee plant as a host of Psocoptera in the Brazilian Amazon region, and the first record of a representative of the family Archipsocidae (Archipsocus lenkoi) for the state of Rondônia. The psocid population was concentrated and not evenly distributed over the survey area, which indicates an irregular distribution pattern. We have not detected damage or injury to the coffee plants and therefore we cannot consider these psocids as a pest in the coffee plantation.

ABSTRACT Macronyssid mites are ectoparasites of terrestrial vertebrates. We slide-mounted and re-examined mite material collected in a 1987-1989 expedition to Maracá Ecological Station, Roraima State, Brazil. The specimens were identified as Acanthonyssus proechimys Yunker and Saunders (Mesostigmata: Macronyssidae), which were collected parasitizing a South American spiny rat, Proechimys sp. This represents the first record of Acanthonyssus in Brazil.

RESUMO: Os objetivos deste estudo foram analisar a atitude e a autoeficácia de professores de Educação física (EF) portugueses, determinar a relação entre as atitudes e a autoeficácia dos professores de EF em relação à inclusão de alunos com deficiência e avaliar o efeito das variáveis independentes (género, tempo de serviço docente, formação complementar em EF Inclusiva e docência ao aluno com deficiência nas aulas de EF e no Desporto Escolar) sobre as dimensões das atitudes e nas dimensões da autoeficácia. Participaram do estudo 115 professores de EF portugueses. Para analisar as atitudes, foram utilizadas a versão portuguesa do Multidimentional Attitudes toward Inclusive Education e a versão portuguesa do Self-Efficacy Scale for Physical Education Teacher Education Majors towards Children with Disabilities. Os resultados indicaram que, de uma forma geral, os professores de EF revelam atitudes mais positivas na dimensão comportamental e são mais confantes para ensinar alunos com deficiência intelectual. Identificaram-se relações positivas entre as diferentes dimensões das atitudes e da autoeficácia. Na análise comparativa das atitudes e da autoeficácia, observaram-se diferenças estatisticamente significativas nas dimensões cognitiva e de deficiência intelectual na variável “formação complementar em EF Inclusiva” e nas dimensões deficiência intelectual e visual na variável “Docência a alunos com deficiência”. De um modo geral, os participantes reportaram atitudes positivas e são confantes em relação à inclusão de alunos com deficiência. A investigação futura deverá comparar as atitudes e a autoeficácia antes e após um programa prático de intervenção ao nível da EF inclusiva.
Test, swarm, normalize: how surveillance technologies have infiltrated Paris 2024 Olympic Games
Authors: Ferrari Matheus Viegas
Published: December 2022

Abstract The present paper aims to discuss the correlation between surveillance technologies and Olympic Games. The latter have become a “security spectacle” only behind wars in terms of budget. Surveillance, however, does not pertain only to security, as it has infiltrated our everyday life and has become a “culture.” To prepare for the 2024 Olympics, surveillance technologies, through an array of innovations, have been put forward in the Parisian territory: from facial recognition cameras and behavioral analysis systems to drones and anti-drone technologies. If it were not for the Olympic context, they would be considered “exceptions.” However, as it will be discussed in the paper, they have been normalized and integrate all the planning dimensions of this sports mega-event.

Published: December 2022

RESUMO Lagoas de polimento são unidades de pós-tratamento de efluente anaeróbio que atuam na remoção da matéria orgânica residual, bem como de patógenos e nutrientes. A operação dessas lagoas de forma intermitente favorece a eficiência de remoção dos constituintes. Neste trabalho, investigou-se o balanço de oxigênio em lagoas de polimento experimentais operadas sob regime de bateladas sequenciais (0,4 m de profundidade e 1,5 m2 de área superficial) com tempo de detenção hidráulica de 10 dias, alimentadas por efluente de reator UASB, sem inoculação inicial com microalgas. O sistema experimental foi instalado no município de Campina Grande, Paraíba, e operado no período de verão (radiação e temperatura elevadas). Os resultados obtidos mostraram que há o estabelecimento de um ambiente aeróbio nessas lagoas, sendo a produção de oxigênio dissolvido pela fotossíntese das microalgas suficiente para atender à demanda pelo consumo de oxigênio dissolvido para oxidação de matéria orgânica, respiração das microalgas e escape atmosférico por dessorção.

Abstract The objective of this work was to evaluate the digestibility of the protein, amino acids, and gross energy of swine liver and meat hydrolysates by Nile tilapia (Oreochromis niloticus). The fish were distributed into 12 tanks with conical bottoms, in a completely randomized design, and fed with the three following diets, with four replicates each: a reference diet with soybean and fish meal; and two test diets, one with swine liver hydrolysate and the other with swine meat hydrolysate. The coefficients of apparent digestibility were high for both hydrolysates, being above 83% for dry matter, 95% for crude protein, and 92% for gross energy. Regarding amino acids, the coefficients remained at 98–100% for the two hydrolysates. The digestibility percentages of the hydrolysates were higher than those of the protein ingredients, both of plant and animal origin, commonly used in the formulation of diets for this fish species. The tested hydrolysates have potential to be used in the formulation of diets for Nile tilapia.

Determining performance of two-tiered GRS walls subjected to traffic cyclic loading
Authors: Ding L. , Liu J. , Zhou T. , Xiao C. , Li H.
Published: December 2022

This study evaluates the performance of two-tiered geogrid-reinforced soil (GRS) walls subjected to traffic cyclic loading considering several influencing factors. These factors herein include the offset distance (D) of walls, the number (N), amplitude (Pmax), and frequency (f) of applied cyclic loading. Seven GRS walls with a reduced scale of 1 : 3 were prepared in the laboratory and employed to investigate their (i) vertical foundation pressures during construction, (ii) load-induced settlements, (iii) facing lateral displacements, (iv) vertical and horizontal earth pressures, and (v) geogrid strains under the action of cyclic loading. Experimental results demonstrate that GRS walls constructed in tiered configurations can effectively reduce vertical foundation pressures. The increasing D, as well as the decreasing N and Pmax, introduces a reduction to the above five mechanical and deformation properties. However, increasing f results in the decrease of wall settlements and facing lateral displacements, and in the increase of others. Performance of several empirical equations for predicting the vertical foundation pressures, location of maximum geogrid strains, and failure surfaces inside walls was examined using the experimental data obtained in this study. Comparisons were also performed to describe the deformation and failure surface modes of the walls after loading.

Published: December 2022

Introduction: the article studies the typology of legal temporality. The changes, evolution, improvement of legal regulation of social relations objectively entail the problem of temporality of legal norms. Consequently, there arise issues of maximum protection for the participants in legal relations, of fair restoration of violated rights in a situation of legislative changes. Purpose: to describe the use of different types of law operation in time (prospective, retroactive, and ultra-active operation). Methods: the study was conducted on the basis of the general philosophical dialectical approach; a system of general scientific and special legal methods was used. The formal dogmatic method and the method of legal interpretation made it possible to clarify the content of the legislative rules on the operation of the law in time. The types of legal norms’ operation in time were identified as a result of combining the legal modeling method and a mental legal experiment. Results: the prospective and immediate effects of legal norms coincide in content and should be treated as identical. The application of the legal norms’ retroactivity is fundamentally different in the branches of public and private law. In private law relations, based on equality of participants, retroactivity of law does not apply to a new law improving the legal status of the legal relationship participants. Due to the absence of both doctrinal and law enforcement certainty regarding the understanding of the rights and obligations arising from, but later than, a relationship, the legislator should define as accurately as possible which rights and obligations fall under the ultra-active operation of an old law and which ones – under the prospective operation of a new law

Abstract. Introduction: the Arctic zone of the Russian Federation is a territory of major economic and geostrategic importance for the country. The growth of conflict potential in the region is accompanied by the rising importance of control over the Arctic space, which is completely impossible without overcoming its extreme economic sparseness, negative depopulation processes, as well as ensuring connectivity through the development of infrastructure projects. In conditions of economic instability, these tasks become an urgent challenge for government bodies requiring a critical analysis of regulating the Arctic macro-region spatial development. Objectives: to identify trends in the implementation of state regulation mechanisms for economic development of the Russian Arctic. Methods: dialectical and formal-logical approaches, retrospective analysis, tabular and index methods, data grouping methods. Results: the interrelated process of the evolution of spatial mechanisms and legal support for the development of the Arctic zone of Russian Federation was analyzed. The latest instruments for spatial development have been considered, namely, support zones for the development of the Russian Arctic and preferential treatment of entrepreneurial activity in the Arctic territories. The leading regions have been identified, i.e., those characterized by the most pronounced positive trends in the implementation of the preferential treatment. Conclusions: the support zones subprogram remained in fact a concept without clear mechanisms to put it into practice, while the preferential treatment of entrepreneurial activity, coming as a replacement, on the contrary, does not have a well-developed concept, but contains specific mechanisms for its implementation. Co-organization of the preferential regime of entrepreneurial activity, the regimes of the territories of advanced socio-economic development and the free port seems to be appropriate within the framework of an improved conceptual approach to managing the spatial development of the Russian Arctic.

Published: December 2022

Introduction: despite the progress in smoking reduction achieved over the past 10 years Russia is still among the leaders of the global anti-rating. the progress in reducing smoking achieved over the past 10 years Russia is still among the leaders of the global anti-rating. The effectiveness of the excise policy as the main instrument begins to decline from the illicit trade, which is expanding due to the inconsistency of the tax policy in the Eurasian Economic Union (EEU) countries. At the same time, the innovative nicotine delivery system market has been expanding, regulation of which is characterized by serious gaps. Objectives: to identify opportunities for improving regulation of traditional tobacco and innovative nicotinecontaining products markets to increase the collection of excises and achieve public health goals. Methods: comparative analysis, retrospective and counterfactual analysis, econometric estimations. Results: for the first time, econometric estimates for the Russian market were obtained on the aggregate regional (panel) data based on the simultaneous equations model using specially generated database “Addictive products in Russian regions”. The estimates show that, ceteris paribus, an increase of 1 p.p. the distance adjusted excise tax difference to the living cost ratio (DATDLC) leads to a reduction in the legal market by an average of 0.16 %. Price elasticity estimate of the legal aggregate demand is (-0.7), income elasticity is 0,8 and price elasticity of supply is 1,5. The analysis of budgetary and market statistics showed a low collection efficiency of excise taxes on ENDS; the problem of fiscal forestalling in this segment has been discovered. Conclusions: the results of the analysis allowed to propose several effective and feasible measures including the creation of an IT-system within the EEU for the exchange of information on excisable goods, the transfer of part of excise revenue to regional budgets, controlled legalization of nicotine pouches, anti-forestalling regulation in ENDS, etc.

Introduction: the successful activity of small innovative enterprises is one of the indicators of a sustainable economy. However, only an insignificant part of those meets the high standards bringing them to innovation ratings. Objectives: to form a profile of the most successful small enterprises engaged in innovative activities, and to determine the parameters of its change for 2016–2020. Methods: general scientific methods of cognition: dialectical, decomposition, synthesis, generalization, analogy, as well as economic analysis. Results: the typology proposed by the authors has been used as the basis for forming a profile of the most successful small innovative enterprises. The typology is based on the frequency of entry in the “TechUspech” rating. The typology features six groups of enterprises: “stable leaders”, “leading”, “aspiring”, “unstable”, “beginners”, “random”. The type of economic activity, regional affiliation, number of employees, revenue growth rate, net profit, goals and types of investment strategy of small innovative enterprises included in the “TechUspech” rating are analyzed. Conclusions: the following profile characteristics of a successful small innovative enterprise presented in the “TechUspech” rating has been received: this is an enterprise in the field of information and communication technologies located in Moscow, St. Petersburg, Novosibirsk or Tomsk regions; rated in “beginners” or “aspiring” groups; with net profit of 100–150 million rubles but showing its fall by 2020; focused on achieving financial stability and reducing investment risks. The biggest changes over the period have been identifies in such parameters as industry affiliation (in 2016, these were enterprises in the “materials and chemistry” and “engineering industries”), regional affiliation (Moscow region, the Republic of Tatarstan, Perm region), net profit (previously positive dynamics was obvious).

Published: December 2022

Limited water availability in future due to climate change may impact wheat yield and the food security. Therefore, it is necessary to find out the agronomic solutions to reduce the drought induce yield losses in wheat. Planting method affects wheat yield by changing the soil water status and root growth. This 2-year study was designed to evaluate the impact of various planting methods along-with water irrigation deficit regimes at different growth stages on wheat yield and net returns. The experiments were conducted in a randomized complete block design with three replications using two-way factorial arrangements. The experiment consisted of five planting methods (PM) viz. conventional broadcasting-PM, ridge-PM, bed-furrow-PM, gap-chat-PM and line-PM; and three water regimes viz., well-watered condition, mild and sever-terminal drought stress (TDS). The results revealed that wheat crop grown under bed-furrow-PM had better morphological growth under well-watered condition, and the crop grown under the same planting method performed better for morphological traits under mild-TDS and sever-TDS during both years. Irrometer Tensiometer was used to check the moisture stress level during terminal drought conditions. Better performance of wheat under mild-TDS and sever-TDS in bed-furrow-PM was the outcome of better antioxidants enzymatic and non-enzymatic activities which was later translated into better wheat yield and high net returns under water stress than other planting methods. In conclusion, bed-furrow-PM is the most suitable method for profitable wheat production in arid and semiarid region under water limited scenarios.
Seeing Streetscapes as Social Infrastructure: A Paradigmatic Case Study of Hornsbergs Strand, Stockholm
Authors: Jing Jing
Published: December 2022

Urban streets are an integral part of the public realm. Streets are commonly planned following normative design principles focused on the connectivity of road networks and urban morphology. Beyond their function as mobility infrastructure, streetscapes’ aesthetic, social, and cultural qualities also have an important impact on the experience of the overall urban environment and human well-being. This study explores how urban design and planning can facilitate the design, management, and use of streetscapes that consider their role as social infrastructure. A paradigmatic case study of Hornsbergs Strand in the City of Stockholm is performed, incorporating spatial and temporal aspects. The case study area is chosen because it is both an attractive and “overcrowded” public space frequently discussed in the Swedish media. Data sources for the study include reviews of public documents such as Stockholm’s city planning strategies, local media reports, a report from a resident workgroup, as well as walk-through observations and semi-structured expert interviews. The results highlight the potential of urban design strategies to develop streetscapes as social infrastructure through both permanent design measures and temporary design interventions. The tendency of the change in people’s perception and attitude toward the place over time illustrates that design interventions are a continual process. The implications for public policy, urban development and investment in social infrastructure employing place strategies and design interventions are discussed.

The article is devoted to topical issues of improving the methodology and organization of fixed assets accounting. Fixed assets play a huge role in the labor process, as they together form the production–technical base and determine the production capacity of the enterprise. Their condition directly affects the activities of the enterprise, namely its continuous operation. Over a long period of use, fixed assets enter the enterprise and are put into operation; wear out as a result of the operation; are repaired, by means of which their physical qualities are restored; leave the enterprise due to obsolescence or inexpediency of further use. Fixed assets used in enterprises in modern economic conditions are one of the most important economic resources. Fixed assets, formed at the initial stage of the organization, require constant management. In the process of accounting at enterprises, there are a number of problems of methodological and practical nature in the organization of accounting, valuation, and depreciation of fixed assets. In the course of writing the article, the economic characteristics and concepts of fixed assets, theoretical aspects of fixed assets accounting, and normative documents related to the researched problem were investigated. The analysis of fixed assets can be carried out in several areas, the development of which in the complex allows assessing of the structure, dynamics, and efficiency of fixed assets and long-term investments. Options for solving problems in accordance with modern economic conditions are revealed. The correct organization of accounting of fixed assets ensures the efficiency of their use, the timeliness of determining and reflecting transactions with changes that occur with them, and the completeness of the reflection of these changes in value terms in accounting. Thus, the fixed asset accounting system needs to be improved. A comprehensive approach to the organization of fixed assets accounting is needed, which is able to provide the necessary conditions and opportunities for the use of valuable accounting information to make management decisions on the evaluation and effective use of fixed assets.

The design of broadband highly-efficient millimeter-wave (mm-Wave) Power Amplifiers (PA) in 22-nm CMOS FD-SOI (fully depleted silicon-on-insulator) is discussed. One design uses fixed biasing while the other utilizes an adaptive biasing network to improve its Power-Added-Efficiency (PAE) in power backoff. These designs aim to cover the key Fifth-Generation (5G) FR2 (Frequency Range 2) band (e.g., from 24.25 GHz to 43.5 GHz). In measurement, the PAs obtain very broadband 3-dB BW, ranging from 19.1 GHz to 46.5 GHz for the fixed-bias design and 18.8 GHz to 41.9 GHz for the adaptively biased design. The adaptively biased design is able to achieve enhanced output 1-dB compression point (OP1dB) and PAE@P1dB because of its adaptive biasing network. Measurements on the fixed-biased PA at 24/28/37/39 GHz yield max. PAE of 22.2/22.4/19.7/19.8%, and POUT,SAT of 14.9/15.3/14.7/14.7 dBm, with OP1dB of 11.8/11.6/12/11.6 dBm, and PAE@P1dB of 14.1/13.4/14.5/13.5%. Measurements on the adaptively biased PA at 24/28/37/39 GHz yield max. PAE of 20.1/15.2/10.3/7.9%, and POUT,SAT of 14.6/14.2/12.5/11.2 dBm, with improved OP1dB of 13.1/12.3/12.1/11.2 dBm, and PAE@P1dB of 19.1/14.4/10.3/7.9%. Data from body bias voltage VB on the PA performance is also presented. These measurement results are compared with post-layout parasitic-extraction (PEX) simulations, and also against other novel silicon broadband mm-Wave PAs in literature.

The water quality of Da Nang Bay (Viet Nam) is one of the major issues on Da Nang City's coast. The discharge of the Phu Loc (PL) channel will be inserted through the outlet into Da Nang Bay. However, the PL channel receives many sources of wastewater so the highly polluted channel water. Therefore, the outlet of PL channel has become the environmental hotspot of the Da Nang Sea. Mike 21 FM Hydrodynamics module coupled with a water quality model using Mike 21 FM ECOLab module is used to simulate water quality and to identify the spreading of NH4+, which is used as a pollutant tracer. Currently, the outlet of PL channel generates the polluted area along the coast in different directions depending on the current and the direction of the wind. This study proposes three scenarios of designing the outlet far from the coastline 400 m, 500 m, and 600 m, respectively. The finding of this research demonstrates that the best way to discharge the wastewater from PL channel would be the outlet to be moved 500 m away from the coastline. NH4+ concentration > 0.2 mg/l will cover an area that distributes about 100 m around the coastline. NH4+ concentration > 0.5 mg/l covers an area approximately 0.03 km2.

In an era of digital transformation, technology has a strong influence on educational organizations. It is a huge challenge for teachers to deal with digital technology. A professional learning community platform integrated with technology is a powerful tool that can improve the digital competency of teachers to manage that challenge. The purpose of this research is to 1) develop a virtual professional learning community platform (VPLC platform) based on an experiential design thinking process, 2) to develop a training course for building digital teacher competency using an experiential design thinking process, and 3) to assess the digital competency of teachers using the VPLC platform in conjunction with the experiential design thinking process. Thirty teachers were selected by multi-stage sampling. The architectures used were the VPLC platform, the experiential design thinking process, and digital teacher competency. The research instrument was a digital competency assessment form for teachers with regard to the VPLC platform and an experiential design thinking process to enhance digital teacher competency. The findings revealed that 1) the VPLC platform model consisted of three components: 1) the VPLC platform, 2) the experiential design thinking process, and 3) digital teacher competency, brought together in four modules: 1) User management module, 2) Content management module, 3) Learner management module, and 4) Analytics management module and five processes: 1) Empathize the Concrete experience, 2) Define the Problem and Reflective observation, 3) Ideate the Abstract conceptualization, 4) Prototype, and 5) Test and Evolution and Active experimentation. The overall result of the quality of a training course in building digital teacher competency with an experiential design thinking process was at the highest quality value (Mean= 4.90, S.D.= 0.31). 3) The overall resulting digital competency of teachers was at the highest level (Mean= 4.80, S.D.= 0.40).

Technology became considerably more critical for mathematics teachers during the Covid-19 pandemic era. Apart from examining pre-service mathematics teachers' knowledge about technology integration, which failed to reflect the unique characteristics of mathematics and underrated teachers' perception toward using technology in mathematics classrooms, this study aims to examine pre-service mathematics teachers' technology integrated competency through an enhancement program. Data were gathered from 25 pre-service mathematics teachers at Lampang Rajabhat University through journals, artifacts, and focus group interviews. Quantitative and qualitative analysis was by the research analytic framework's categories to define changes in participants' technology integrated competency. The primary finding was that participants gained a better knowledge of technology integrated lesson design during a four-month period. Most participants moved their emphasis away from technology as a teaching aid and toward providing students with mathematical learning instruments. Additionally, they emphasized the significance of their courage. They did not overlook the necessity of adequate mathematical knowledge for teaching when it came to improving mathematics teachers' roles in creating a successful technology integrated mathematics lesson. It was discovered in this study that the cooperative initiation and open lesson observation of pre-service mathematics teachers had a direct effect on their lesson preparation.
