The Practice of Practical Multicultural History Learning on the Topic of ‘Korean Diaspora, Koryo People’
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Heo Young-hoon
Published: May 2024

Objectives This study has an autobiographical character as it is a study that looks back and reflects on ‘my’ class based on my experience at K Elementary School. In the process of research and practice, I continuously tried to reflect the contextual characteristics of the school and region. I recognized the characteristics of the village's mul-ticultural situation, the current status of K Elementary School, the situation faced by Koryoin students, the diffi-culties in communication between Korean and Koryoin students, and the difficulties that fellow teachers face in teaching Koryoin students. Based on this awareness, we designed and implemented a practical multicultural his-tory class for solidarity and togetherness beyond discrimination.
Methods First, the topic of forced migration of Koryo people, a minority history, was reviewed from the per-spective of memory and forgetting, and the direction of practical multicultural history education was set through analysis of multicultural education theory and curriculum. Next, I designed and implemented a practical multi-cultural history class on the topic of forced migration of Koryo people and analyzed the process and results.
Results The analysis and implications are that, first, the memory of the forced migration of Goryeo people, a for-gotten minority history, was discovered and recalled. Second, it is the acquisition of multicultural com-petency(cultivation of multicultural cultural literacy) based on empathy and interculturalism beyond the assim-ilationist perspective. Third, they had participation and practical experience for solidarity and companionship. Fourth, I looked back on what kind of multicultural teacher I am as a teacher who practices multicultural education.
Conclusions The implications of the study are that, in terms of research methods, history classes were autobio-graphically reflected and analyzed based on personal memory data and accumulated cultural artifacts (research notes, student output, photos, videos, etc.). Through this, teachers in the field will be able to understand the de-sign and execution aspects of history classes in detail and use it as a reference for their own class practice research. Next, in terms of research content, history education was practiced with the theme of multiculturalism. Because I recognized the limitations of traditional history education and designed and implemented practical mul-ticultural classes by reflecting the contextual uniqueness of local communities and school, it can be a meaningful reference for schools in multicultural situations. Lastly, the focus on the history of minorities, the Koryo people and forced migration of Koryo people, can be a good example of migration history education.
A study on unconscious learning: Focusing on Deleuze's concept of learning-subject
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Bae Ji Hyun , Gim Chae Chun
Published: May 2024

Objectives This study aims to illustrate that learning occurs at the learner's unconscious rather than conscious level by exploring Deleuze's theory of ontology/subjectivity.
Methods Leibniz's monadology and ontology were utilized to study crucial components of Deleuze's ontology and subjectivity. The nature of the learning-subject in Deleuze's theory of learning was also investigated in light of these entity and subject theories.
Results This study shed light on the ‘learning-subject as an unconscious expressive subject’ idea given by Deleuze's ontology/subjectivity theory. The unconscious learning-subject can be drawn from Leibniz's notion of ‘diverging monads’ and Deleuze's theory of ‘intense body’, which is presupposed in operating in ‘a zone of embry-onic-larval expression below awareness or before individuation’.
Conclusions Learning happens at the level of unconsciousness, which is the level below awareness, in accordance with Deleuze's learning-subject theory.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Choi JaeHyeok , Son Yeon-A , Oh HyunJeong , Maeng HeeJu
Published: May 2024

Objectives This study analyzed whether environmental education instructors' perception of the value of ESD, their degree of practicing environment-friendly behavior, and their PCK for ESD were significantly different depending on their experience in applying ESD, and considered the implications.
Methods For this purpose, the survey questions were constructed and a survey was conducted targeting environ-mental education instructors active in Seoul and Gyeonggi-do from September to November 2023. Accordingly, an independent samples t test was performed on the survey data of a total of 83 environmental education in-structors using the SPSS statistical program to analyze significant differences according to ESD application experience.
Results First, environmental education instructors appeared to have a very positive perception of the value of ESD, and it was analyzed that there was no significant difference depending on ESD application experience.Second, en-vironmental education instructors with ESD application experience were found to have statistically significantly higher ESD class composition ability and ESD teaching strategy ability than environmental education instructors without ESD application experience, and ESD teaching and learning environment creation ability and instructor ability. It was analyzed that there was no significant difference in professional development efforts.Third, there was no significant difference in the degree of practicing eco-friendly behavior at an individual level according to the environmental education instructors' experience in applying ESD. However, the level of practice of environ-mentally friendly behavior at a collective level among environmental education instructors with ESD application experience was found to be statistically significantly higher than that of environmental education instructors with-out ESD application experience.
Conclusions However, the PCK of environmental education instructors with experience applying ESD was found to be somewhat higher than the average level. Therefore, the implications were considered that there is a need to establish a continuous and systematic governance support system so that environmental education instructors can cultivate PCK for ESD and experience various ESD-related activities.
The Effects of Basic Psychological Needs on Career Preparation Behavior: Dual Mediating Effects of Intrinsic Motivation and Self-Directed Learning
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Kwon Dayoung , Kang Seunghee
Published: May 2024

Objectives The purposes of this study was to examine the relationship between basic psychological needs and career preparation behavior and verify the mediating effect of intrinsic motivation and self-directed learning.
Methods A total of 220 university students majoring in aviation service completed the self-report questionnaires including basic psychological needs, intrinsic motivation, self-directed learning and career preparation behavior and then analyzed through SPSS23 and PROCESS Macro. Model 4 and Model 6 was used to verify the mediating effect and dual mediating effect consecutively and bootstrapping was performed to verify the significance of the mediating effect.
Results The results showed statistically significant positive correlations between basic psychological needs, in-trinsic motivation, self-directed learning and career preparation behavior. Additionally, intrinsic motivation and self-directed learning mediated the relationship between basic psychological needs and career preparation be-havior respectively. Finally, the relationship between basic psychological needs and career preparation behavior was sequentially mediated by intrinsic motivation and self-directed learning.
Conclusions These findings suggest that intrinsic motivation and self-directed learning may have greater impacts on career preparation behavior than basic psychological needs. Other implications and limitations of this study are discussed, along with suggestions for future studies.
A Study on the Differences in ESG Awareness Levels and Importance Among University Students Based on Demographic Characteristics and the Presence or Absence of ESG Education
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Jo Hyeyoung
Published: May 2024

Objectives The purpose of this study is to analyze the differences in ESG awareness and importance among uni-versity students based on their demographic characteristics, as well as awareness and education regarding ESG.
Methods The subjects of this study include 301 undergraduate students enrolled at a four-year university. Using SPSS 23.0, the characteristics of the study population were analyzed in terms of frequency (%), and the reliability coefficient, trend, and normality of the research variables were examined. Differences between groups were ana-lyzed by t-test and ANOVA, followed by Scheffé's post hoc test.
Results The main research findings are as follows. First, there were no statistically significant differences in the levels of awareness and importance of ESG factors among groups of university students based on gender, age, and major. In terms of grade, the awareness levels for overall ESG perception, as well as for the E and G perception factors, were higher in the second year compared to the fourth year. However, there was no statistically significant difference in the perception level of S. Grade level showed statistically significant differences in both the im-portance of ESG and its subfactors, with juniors and seniors perceiving ESG as more important than freshmen. Second, the analysis of differences in ESG awareness levels and importance, based on whether university stu-dents are aware of ESG, revealed that across all factors, students who are aware of ESG showed higher levels compared to those who did not. Third, the analysis of differences in ESG awareness levels and importance based on whether university students received ESG education revealed that, across all factors, students who underwent ESG education showed higher levels compared to those who did not.
Conclusions This study confirms the importance of ESG and education as perceived by university students. This article aims to propose approaches that focus on implementing ESG in universities.

Grit showed a complete mediating effect in the effect of parental learning support on learning attitude, and Grit showed a partial mediating effect in the effect of supportive school environment on learning attitude.
Conclusions Parents' learning support and supportive environment had a positive effect on Grit, which improved the learning attitude. This study is expected to help parents, who are interested in their children's learning, support direction and school environment by examining the influence and path of parents‘, school variables and grit that can positively affect learning attitudes.
Analysis of Trends in Science Electives in the High School Credit System: Focusing on Chemistry I Subjects
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Shin Dong-Seon
Published: May 2024

Objectives This study investigated and analyzed the tendency of students to choose subjects and the tendency of chemical academic achievement according to science subject selection in the high school credit system.
Methods For six months, from March to August 2020, 339 sophomores of S High School located in Gyeongnam were surveyed and analyzed for their perception of subject selection. Among them, a questionnaire was devel-oped to find out the perception of the content of chemistry subjects, and a questionnaire was conducted on 78 people who agreed to participate in the study. In order to analyze the tendency of chemical academic achievement according to science subject selection in the high school credit system, descriptive statistics, cross-analysis, and nonparametric tests were performed with the SPSS 28 program.
Results Students selected many of the science elective subjects in the order of 'Chem-Phys-Bio,' 'Chem-Phys-Earth,' and 'Chem-Bio-Earth.' In the content and concept of the Chemistry I subject, students were found to have difficulty understanding concepts such as 'mole,' 'chemical reaction formula,' 'orbital,' etc., and the 'Chem-Phys-Earth' subject group was found to have the most difficulty in understanding the concept of 'mole.' In addition, in the comparison of achievement by elective subject group, the 'Chem-Phys-Bio' subject group showed the highest chemical academic achievement and the 'Chem-Phys-Earth' subject group showed the low-est achievement.
Conclusions In the high school credit system, students chose the Science I course independently, but many stu-dents were found to have insufficient understanding of the basic concept of Chemistry I. Therefore, in terms of understanding the concept of chemistry, it is essential to design a teaching-learning process by level so that stu-dents can better understand the basic concept of Chemistry I in the high school credit system.
Fiqh al-azma: Crisis Management of Theological Discourse in Syria
Authors: Zaripov I. A.
Published: May 2024

In the context of the ongoing civil war in Syria, the official Muslim clergy of the country, represented by the Ministry of Waqf Affairs, has developed a number of theological and legal resolutions on the most pressing issues, united by the common names Fiqh al-Azma (“crisis theology”). They pay special attention to the issues of criticism of takﬁrism, non-denominationalism, nationalism, explaining the meaning of jihād, the prohibition of riots and revolutions, the religious legitimacy of the national state, interreligious and interfaith dialogue and collaboration within one country, the differentiation of the concepts of Islamic politics and political Islam. This study analyzes the sources and methodology of constructing this theological concept, which, according to the developers themselves, is an example of a moderate renewal (tajdīd) of Islamic theological discourse, the main purpose of which is to confront Fiqh al-Fitnah “theology of turmoil” preached by various extremist groups. The paper also examines an example of one of the most original studies — on the principles of citizenship (muwāṭana) according to Islam, which largely incorporates the main features of the entire concept of Syrian crisis theology.

Published: May 2024

Este trabalho decorre de pesquisa exploratória, de método misto, tratando da precarização do trabalho docente no Brasil, a partir da sistematização de dados do Censo Escolar do Instituto Nacional de Estudos Pedagógicos – INEP, 2022. Foram analisados os números de docentes com contratos temporários, para identificar os vínculos precários no magistério em estados e municípios. Considerando esses dados, as redes estaduais e municipais possuem 360.913 e 405.905 contratos temporários. Parte das redes de ensino descumprem o Plano Nacional de Educação – PNE, que estabelece o percentual de 90% de professores/as efetivos/as. Os contratos temporários prejudicam a valorização da carreira docente e a qualidade da educação pública. Para valorizar o trabalho docente, é preciso garantir segurança profissional, formação adequada e igualdade de oportunidades. A realização de concurso público para a efetivação de professores/as é uma medida que assegura esses direitos, além de fortalecer a gestão democrática e participativa nas escolas.

Published: May 2024

Este estudo busca desvelar desafios enfrentados por professoras alfabetizadoras no pós-pandemia, através de pesquisa de campo de abordagem qualitativa, com grupo focal constituído por três professoras da rede pública de Campinas/SP. Os resultados apontam que atividades pedagógicas não presenciais durante a pandemia não alcançaram todos/as os/as estudantes ou chegaram para sua maioria de forma pouco satisfatória, gerando dificuldades na alfabetização – razão pela qual são necessárias ações para a recomposição de aprendizagem, acolhimento emocional e saúde mental para estudantes e professores/as que necessitem. A garantia da alfabetização no pós-pandemia desafia a comunidade escolar, requerendo prioridade política, investimento público potente e ações permanentes que permitam a estudantes o direito à educação. Desigualdades precisam ser tomadas como critérios de análise da realidade e formulação de políticas e estratégias pedagógicas, possibilitando superar defasagens de aprendizagem e construir novas realidades educacionais para estudantes, principalmente os/as mais vulneráveis.

Fibroelastoma is a rare cardiac tumor that can cause embolization, stroke, myocardial infarction, heart failure, and cardiac arrest. Here, we report the case of a 45-year-old male who presented with right-sided weakness and fever. He was diagnosed with acute right frontal infarction and was found to have Streptococcus sanguinis bacteremia. Upon confirmation of a positive blood culture after 24 hours, treatment for endocarditis was initiated. Transesophageal echocardiography revealed findings highly suggestive of a papillary fibroelastoma (PFE). PFE ought to be regarded as a potential differential diagnosis in individuals who exhibit symptoms of fever, thromboembolism, and persistent bacteremia. Non-invasive imaging such as echocardiography is of great value in the diagnosis of PFE, while surgical resection remains the best treatment modality to overcome current and future associated complications.

We describe the natural history of a three-month-old patient with Hunter Syndrome with hematopoietic stem cell transplant (HSCT) who developed recurrent diffuse alveolar hemorrhage (DAH) requiring extracorporeal membrane oxygenation (ECMO). The patient underwent HSCT with several complications, including veno-occlusive disease and DAH. He was managed with ECMO. Unfortunately, despite initial success he developed recurrent DAH and ultimately died. This is a novel report of this severe adverse event requiring ECMO following the use of HSCT in this rare patient population. We share the clinical strategies employed to address the complications associated with HSCT and the progression of his disease over his hospitalization.

Background/Aim. Chronic pulpitis (CP) is an inflammatory dental pulp disorder associated with various pathophysiological mechanisms in its origin. The aim of the study was to evaluate the changes in the pulp tissue of osteoprotegerin (OPG) and tumor necrosis factor (TNF)-? and establish their relationship with the histological changes of pulp tissue, as well as with the micromorphological changes, occurring in the mineralized tissue. Methods. The study examined the dental pulp of 41 patients with CP and 12 healthy individuals. The group of the diseased subjects was subdivided based on the presence of communication of the pulp with the oral cavity, i.e., open (n = 22) or closed (clausa) (n = 19) CP. Results. The levels of TNF-? were statistically significantly increased, while OPG levels were decreased in the pulp of patients with CP, compared to the control group. TNF-? levels were almost the same in the pulp of patients with closed CP and the control group, while values were significantly increased in those with open CP compared to control. Histopathological analysis showed a significant increase in the number of mononuclear inflammatory cells in the diseased pulp. Scanning electron microscopy showed distinct changes, which correlate with internal resorption. Conclusion. The results indicate a much greater and intensified process of root resorption in patients with closed CP, which is unassociated with dental pulp OPG and TNF-? level changes.

Published: May 2024

Objectives

To assess skeletal and dental effects and evaluate possible side effects of maxillary expansion with two different appliances, directly after expansion and 1 year postexpansion.

Materials and Methods

Forty-two patients with unilateral posterior crossbite (mean 9.5 ± 0.9 years) were randomized to either rapid maxillary expansion (RME) banded on the deciduous second molars and bonded to the primary canines or slow expansion with quad helix (QH) on the permanent first molars. Cone-beam computed tomography records were taken at baseline, directly after correction of the posterior crossbite and at follow-up 1 year after expansion.

Results

All patients were analyzed. RME opened the midpalatal suture more anteriorly and inferiorly (mean 4.1 mm) and less posteriorly and superiorly (mean 1.0 mm). No effect on midpalatal suture could be shown in the QH group after expansion, P < .001. Buccal bone width had significantly decreased (P < .001) in the QH group compared with the RME group. Buccal fenestrations and root resorption on the left first molar had a higher prevalence directly after expansion finished in the QH group (P = .0086, P = .013) but were not significant at 1-year follow-up (P = .11, P = .22).

Conclusions

Opening of the suture with RME was more anterior and inferior, and the QH did not open the midpalatal suture at all. More buccal bone loss and fenestrations were seen on the permanent first molar in patients treated with conventional QH than RME anchored to deciduous teeth.

Authors: Almeida Wallace Carriço de , Santos Rosemary dos , Amaral Mirian
Published: May 2024

Neste artigo, inspirado em pesquisa realizada em uma universidade pública e em discussões em nossos grupos de pesquisa, objetivamos compreender como os memes potencializam autorias, interlocuções e colaborações acerca das relações sociais, políticas e culturais, na educação online. Para isso, adotamos como metodologia a bricolagem da ciberpesquisa-formação (Santos, 2019) à multirreferencialidade (Ardoino, 1998) e à abordagem das pesquisas com os cotidianos (Certeau, 2013), o que propiciou a emergência de narrativas autorais - textuais, sonoras e imagéticas, em diferentes formatos e linguagens, na produção crítica de memes voltados às práticas dos alunos, reveladora de seus dilemas e promotora de novos contextos de aprendizagem significativa.

Change in Marriage Behaviour in North-Central Namibia 1925–2009
Authors: Notkola Veijo J , Siiskonen Harri , Shemeikka Riikka
Published: May 2024

Namibia is the only country in Africa for which historical data is available to describe the change in marriage behavior since the 1920s. The aim of this article is to describe and to understand how the age at first marriage changed and how it was related to cohabitation since the 1920s in Namibia. The description of changes is based on parish register material and the family reconstitution method. The mean age at first marriage was over 20 for both sexes as early as the 1920s. In 1945–49, the mean age at first marriage started to increase, reaching about 29 for men and 24 for women at the end of the 1950s. The explanation for the increase was labor migration. The new cohabitation model was introduced from the end of the 1970s to the 1980s. Features of this model were cohabitation before marriage, late marriage age, a low married proportion of the population and high proportion of premarital births.

Authors: Neyer Gerda , Andersson Gunnar , Dahlberg Johan
Published: May 2024

The Swedish Generations and Gender Survey 2021 (GGS2021) was the second GGS that Sweden carried out. It was a web-based survey with a paper-based option. Like the first GGS in Sweden (GGS2012) it was linked to register data that cover key dimensions of respondents’ life courses. The Swedish GGS2021 contains two new modules implemented to further research on the link between subjective perceptions and fertility. Both modules will be part of the second wave of the international GGS standard questionnaire. In this contribution, we first describe our motivation to carry out the SwedishGGS2021. We then present our two new modules and sketch their theoretical underpinnings. This is followed by a summary of the data collection process and an assessment of data quality. We conclude with some reflections on the implementation of new modules in future international GGSs and on our experience with register-linked surveys.

Authors: Hamidou Cephas Atirbi , Nourou Mohammadou , Abdala Zédou
Published: May 2024

The objective of this paper is to examine the effects of mayors’ human capital on the investments of northern Cameroonian municipalities. The human capital of mayors is operationalized in terms of the level of education (diploma), training, and age. The data in the study are from 46 councils in northern Cameroon, including 21 in the Adamawa region, 12 in the north, and 13 in the far north. After carrying out the preliminary statistical tests (multicollinearity and homoscedasticity) for the cross-sectional data, the result of OLS shows that the human capital of mayors has an effect on the investments of northern Cameroonian municipalities. Particularly, the level of education of mayor (as measured by the diploma) has positive effects on municipal investments. However, the coefficients of educational attainment and age of mayors are not significant. The result also shows that the coefficients of some control variables are statistically significant.
Prevalence and Antibiotic Susceptibility of Gram-Negative Bacteria Isolated from Different Meat Samples in Baghdad City
Authors: Hadid Mustafa , . Al-Shaibani Abdulwahid , Al-Halbosiy Mohammad
Published: May 2024

Background: The occurrence of Gram-negative (G -ve) bacteria in meat samples raises a major concern due to the possibility of drug resistance incidence since G -ve bacteria have built-in resistance mechanisms and can pass on genetic elements that enable other bacterial species to develop into drug-resistant as well. This drug resistance could be transferred to consumers through a food-borne route. This study aimed to evaluate the prevalence of Gram-negative bacteria in meat samples as well as to detect their antibiotic susceptibility patterns. Methods: For this purpose, 100 meat samples (ground meat, raw burgers, frozen chicken, and chicken carcasses) were collected, and obtained isolates were identified using conventional microbiological techniques including cultural and microscopic identification. After that antibiotic susceptibility patterns were detected using Kirby Bauer's disc diffusion method. Results: Results showed that 91 of the samples were harboring Gram-negative bacteria and E.coli was the most common isolate (51.64%) followed by Klebsiella pneumoniae (18.68%) while the least common isolate was each of E. coli O157:H7, Aeromonas hydrophila, Kluyvera spp., Raoultella terrigena, Hafnia alvei, and Serratia marcescens (1.10%). Susceptibility test showed that all isolates were susceptible to Meropenem and Imipenem while Ampicillin was the most resisted antibiotic. Conclusion: We conclude that meat samples harbor numerous pathogenic Gram-negative bacteria which showed antibiotic-resistant ability toward most tested drugs. However, Meropenem and Imipenem were the least resisted drugs which makes them an appropriate choice for the treatment of foodborne infections.

Published: May 2024

Hydro-meteorological hazards are a major issue in many regions of the world, including Romania. Among these, flash floods are the most frequent phenomena, generating significant annual socio-economic and environmental damages. In recent years, flash flood forecasting using machine learning algorithms has become an useful tool for data-based hydrologic modeling. Machine learning allows to create mathematical relationships between the river discharge and other climatic and physico-geographic parameters from the training dataset. This paper aims to perform a scientometric analysis using open-source programs, namely ScientoPyGui and VOSviewer. The expression ‘flash flood forecasting AND machine learning’ was searched in the Web of Science and Scopus databases. After merging and removing duplicates, 112 publications were retained for analysis. Their number has increased by 60% in the past three years (after 2021) with a trend towards a sub-branch of machine learning, namely deep learning. The spatial distribution of the papers showed that China is a global leader with 25% of the total. These findings highlight the increasing role of machine learning based models (particularly deep learning) in enhancing flash flood forecasting, a nonstructural measure for the flash flood risk mitigation

Published: May 2024

One of the major problems in the engineering design of water resource is the estimation of peak flood flows. In probability theory and statistics, flood frequency analysis is used to obtain the distribution of flood probabilities. Gumbel distribution represents distributions of extreme values used in hydrological studies to predict flood peak, maximum rainfall, etc. This paper aims to analyses the frequency of floods, Gumbel's frequency distribution method, based on the maximum annual flows in the Timis River for the period of 30 years (1993 – 2022). For this analysis the return period (T) used is 5 years, 10 years, 50 years, 100 years, 150 years.

The purpose of this paper is to highlight the spatial-temporal distribution of hydrological alert messages issued at the national level in the last two years, with a special focus on the accomplished percentage of the forecasted projected information. This paper used information from the database generated within National Institute of Hydrology and Water Management as part of the National Administration of Romanian Waters (NARW), which is the national authority to elaborate and distribute the warnings and alerts for immediate phenomena in Romania. The criteria for validating the hydrological warnings were based on the achievement of the predicted stream defense water levels, reaching precipitation thresholds or the existence/evidence of recorded damages. The actual analysis was carried out on the major hydrographic basins associated with the regional basin administrations. Three particular case studies were also analyzed, which spatially cover three distinct heterogeneously positioned regions, in order to have a better representativeness: the upper part of Someșului Mare river, the Bistrița, Moldova and Suceava rivers in Suceava county and the lower basin of Jiu River with its tributaries, as well as the Danube River on its sector within Iron Gates II Dam and its confluence with the Jiu River.

Knowing hydraulic parameters is very important in the design of spillways, which are the safety structures of dams. While obtaining these parameters, traditionally theoretical and empirical approaches are used and scale model experiments are performed. Today, with the increase in computer processing capacity, numerical modeling techniques are used as an alternative to long and costly experimental studies. In this study, the pressure parameter changing along the longitudinal section in the chute spillway was examined using computational fluid dynamics (CFD). In the 3D CFD model of the spillway, the VOF method and the standard k-e turbulence model, which can solve two-phase flows, were used for the design discharge. The obtained pressure parameter results were examined and interpreted along the spillway section. According to the pressure results obtained as a result of numerical analysis, points along the spillway where cavitation may occur have been determined.

The study of the variation of the hydrological regime in hydrographic basins is a necessity in the context of climate change. Based on the forecast of flow and level variations, water resources management plans are drawn up. The paper deals with the subject of simulating the phenomenon of rainfall - runoff with the help of the advanced hydroinformatics tool MIKE by DHI. The data used represent the precipitation and flows recorded in the Turnu Ruieni section, on the Sebes river, between the years 1988-1997, 2005, respectively the year 2021. A comparison is made of the maximum discharge values obtained from the simulation in the years 1988-1997, 2005 and 2021 (the difference of 33 years, approximately the duration of a hydrological cycle); a comparison is made between the discharges on the Sebeș River, in the years 1988-1997, 2005 and 2021, respectively between the amounts of recorded precipitation. The MIKE11byDHI program is used, the Rainfall – Runoff (RR) module, based on the UHM (Unit Hydrograph Model), the CN “Curve Number” method, the SCS (Soil Conservation Service) method.

Against the background of an increasingly restricted mining activity at the national level, due to the high economic costs, the active and conservation mining objectives sporadically register environmental incidents, which affects mainly the aquatic environment. Thus, in the context of excess rainfall, internal erosion processes associated with dikes and structures related to tailings ponds, poor management of the galleries under conservation can lead to the triggering of accidental pollution with mine waters and wastewaters from tailing ponds of the natural hydrographic network. The analysis of these events was done both from the perspective of spatial and temporal distribution, with a focus on the nature of involved polluting substances and the transfer of pollution waves on the local and regional hydrographic network system. The paper used information from the database of the Romanian National Water Administration, obtained as a result of the post-event investigations carried out through the Water Basin Administrations and their associated laboratories for the period 2017-2023.
