Challenges and advances in the study of gram-negative bacteria
Authors: Hernández Bridon Nairobi
Published: November 2024

Introduction: the categorization of a bacteria as gram-negative responds to the staining and coloring it takes during the biochemical identification process using Gram staining. There have been multiple antecedents in relation to the study of bacteria, especially gram-negative ones. Objective: describe the challenges and advances in the study of gram-negative bacteriaMethod: in relation to the central theme of this research, a bibliographic review was developed. Search terms and their English equivalents were used. They were applied in search engines such as Google Scholar and databases such as Scielo Regional, PubMed and SCOPUS. We worked with 21 investigations to write this work. Development: Gram-negative bacteria share similar characteristics in terms of their structure in relation to Gram-positive bacteria. However, its main difference lies in the constitution of the wall. Research in the health sciences, especially in the area of microbiology, focuses mostly on the diagnosis of causal agents and the improvement of procedures for their confirmation. At the same time, they provide invaluable information on the basic characteristics of these agents that allow their identification and those that have changed over time. Every scientific advance finds relevant information, as well as new challenges for researchers. These challenges lay the foundations for new questions and unmask new horizons in search of new information on the topic investigated. Conclusions: in relation to advances, they have focused on determining the resistance capacities of bacteria, in coordination with their behavior in the environment and how these data could influence therapeutic alternatives. For their part, the challenges contribute to the improvement of the processes, especially from a technological point of view, to guarantee greater focus on the research carried out
Biofilm: the invisible fortress of bacteria
Authors: Hernández Bridon Nairobi
Published: November 2024

Introduction: Biofilm is an organized and multidimensional association of biological agents that are located within an extracellular matrix composed of polysaccharides (polymeric), as well as proteins, mineral salts and DNA. Together with cellular remains that represent 10 or 20% of its compositionObjective: characterize antimicrobial resistance from the point of view of the BiofilmMethod: A bibliographic research was developed. Scielo, SCOPUS, and PubMed databases were used using the search terms and their English equivalents. After reviewing the title, summary and application of the inclusion criteria, we worked with 25 investigations. Development: the composition of Bioflim is described as a complex organization, which gradually gains structure. The Biofilm compound is typical of gram-negative bacteria as a result of its high resistance capacity. The regulatory process for the formation of compound Biofilms is based on complex networks of regulators. One of the compounds demonstrated in this system is quorum sensing or autoinduction. For a Biofilm compound to be considered harmful or associated with antimicrobial resistance, a series of characteristics must be present. Conclusions: Biofilm constitutes a biofilm made up of a heterogeneous group of molecules that give it similar characteristics, as well as peculiar ones for each of the bacteria. Its organization in structures, of greater complexity as the formation process progresses, allows it to respond to the adversities of the environment and a high capacity for antimicrobial resistance. Its composition and formation varies with each stage. For the most part, it is typical of gram-negative bacteria, which is the basis for their high capacity for resistance

Authors: Jumain  , Rasiman Noviany Banne
Published: November 2024

Introduction: Diabetes mellitus (DM) type II is a disease characterized by increased blood sugar levels which can cause many complications. The complications of DM that often occur are skin damage and diabetic foot wounds, because in general patients are not aware of the presence of ulcers due to the neuropathy they are experiencing. The risk of foot injuries can increase the need for treatment and care in patients. However, the risk of foot injuries can be detected early by the patient independently by carrying out regular examinations of the patient's feet. Providing foot care can reduce the incidence of skin damage and the risk of diabetic foot wounds.
Objective: The aim of the research is to analyze the effectiveness of foot care in preventing skin damage and the risk of diabetic foot wounds in diabetes mellitus patients.
Method: This research method uses a quasi-experimental design with a pretest posttest one group design. This research was conducted at the Undata Hospital in the Bougenvile room with a population of 31 participants. The selection of respondents was based on inclusion criteria, namely: age ? 30 years and suffering from DM.
Result: The results of the analysis used the paired sample t-Test. The average skin damage prevention score for DM patients before giving foot care was 2.97 and the skin damage prevention score after being given foot care was 2.52, respectively, experiencing a decrease in skin improvement of 0.45. These results show that the average value of diabetic ulcer risk for DM patients before being given foot care was 2.81 and the average value after being given foot care was 2.16 with a difference in improvement in the risk of diabetic ulcers of 0.65 which shows that the p-value is 0.000 < ? (0.005) then H0 is rejected and H1 is accepted. This shows that there is an effect after being given effective foot care on preventing skin damage and the risk of diabetic ulcers in DM patients at Undata Regional Hospital.
Conclusion: This research proves the influence of the effectiveness of foot care on preventing skin damage and the risk of diabetic ulcers in DM patients at Undata Hospital.

Introduction: Stunting is one of the most common impacts of chronic malnutrition in the world. Banjar Regency is one of the regencies in South Kalimantan that has experienced a significant increase in stunting cases. Mothers often act as the primary caregivers of children, thus all actions taken by mothers related to care including fulfilling nutritional needs can affect the health and nutritional status of their children. It is important for a mother to have good knowledge about fulfilling nutrition for children, fulfilling immunizations, maintaining sanitation and treating infectious diseases in children. One way to gain knowledge is from experience. Mothers with stunted children have experiences that can be lessons regarding the actions taken during treatment, the obstacles felt and how to prevent stunting in the next generation.
Objective: This study aims to explore the experiences of mothers in caring for children with stunting in the riverside of ??Banjar Regency.
Method: A qualitative approach with a phenomenological design was used in this study. Data were collected using the in-depth interview method and analyzed using the sequence: transcribing, categorizing, using N-Vivo 12. The population in this study were all mothers who had stunted children in the riverside of ??Banjar Regency. In this study, mothers who became participants were selected using a purposive sampling method, namely data was taken from information from health center officers in Banjar Regency with inclusion criteria having experience caring for children with stunting, being able to communicate well and being willing to be participants. Data saturation was obtained on the 16th participant.
Result: The results of this study identified 5 themes, namely children's eating habits, children's conditions, mothers' efforts, mothers' difficulties and the role of fathers. Children's eating habits include incomplete menus, eating little, eating irregularly, eating without side dishes, and snacks before eating. The condition of stunted children in this study was slow development, frequent illness, and poor sleep quality. Mother’s efforts were to provide exclusive breastfeeding and routinely go to posyandu. The difficulties faced by mothers were difficulty in accessing health facilities, economic problems, children who did not want to be separated from their mothers, confusion in handling stunting and the presence of a closed mouth movement in children. The role of fathers included collaborating with mothers in parenting and being less involved in parenting.
Conclusion: The conclusion obtained in this study was that 5 themes were obtained from the experience of mothers in caring for children with stunting in the riverside of Banjar Regency.

Text Considerations to Motivate Boys to Want to Read
Authors: Williams Lunetta
Published: November 2024

Increasing motivation to read among elementary boys is an important consideration in closing the gender achievement gap in reading as students who are motivated to read typically increase their reading volume which can positively impact reading achievement. This article discusses the following text considerations that can impact boys’ motivation to read: (a) topic; (b) genre; (c) series, and (d) text layout. It is critical that books with these text considerations are accessible in classroom libraries, as male students in previous studies have not found texts of interest at school. The article provides a checklist for teachers to self-evaluate the types of texts that are needed in classroom libraries that can appeal to male students.
KESADARAN PENDETA DALAM BERPOLITIK SE KOTA SORONG
Authors: Luturmas Paulus
Published: November 2024

Kesadaran dalam berpolitik sebagai seorang pendeta, sangat dibutuhkan untuk mengingatkan yang bersangkutan dalam menyadari keadaan, tetapi juga setelah mengerti tugas dan tanggung jawab dalam keterlibatan di dunia politik. Mengapa dikatakan demikian oleh karena keterlibatan seorang pendeta dalam berpolitik adalah menegakkan keadilan, kejujuran serta kebenaran yang walaupun nanti mendapat tantangan, akan tetapi, kesadaran itu sangat penting dalam soal berpikir, bertindak dan berbicara. Hal penting yang perlu dipertimbangkan oleh seorang pendeta yang mau terlibat dalam politik atau yang sudah terlibat dalam politik adalah menyangkut motivasi.  Artinya, seorang pendeta perlu bertanya dalam dirinya, apa motivasi saya untuk terlibat dalam politik.  Pertanyaan inilah yang akan menentukan apakah seorang pendeta boleh atau tidak boleh terlibat dalam politik.  Kalau motivasinya adalah untuk memuliakan Tuhan atau untuk membuat Kerajaan Allah semakin jaya melalui percaturan politik maka tidak salah bila seorang pendeta mau terlibat dalam politik.  Tetapi kalau motivasinya hanya untuk meningkatkan kesejahteraannya karena mungkin selama ini dalam kekurangan, maka sebaiknya pendeta tidak boleh terlibat dalam politik.

Authors:   The Korea Society Of Educational Studies In Mathematics, Ku Nayoung
Published: November 2024

This study aims to identify how preservice elementary teachers design tasks using Algomath and draw implications for preservice teacher education and the development of AlgeoMath. The tasks designed by 14 elementary preservice teachers were analyzed, focusing on rules of actions and operational invariants using AlgeoMath. We found that there were certain units and features that preservice teachers chose to use AlgeoMath, and they were most likely to use AlgeoMath’s tools to increase efficiency over the pencil and paper context, and less likely to allow for exploration than the pencil and paper context. Based on the preservice teachers’ tasks, we suggest what is needed in development AlgeoMath for elementary school students and what should be specifically focused on in preservice teacher education.

The purpose of this case study is to analyze the students' level of covariational reasoning revealed in solving the task of constructing qualitative graphs. The classes for this study were conducted on 6 students who had not learned functions and graphs in school mathematics, divided into 3 groups of 2 each. In the retrospective analysis after the class was over, the shapes of the graphs drawn by the students in the task of constructing a quantitative graph were similar, but there were notable differences between the students in the shapes and explanations of the graphs drawn in the task of constructing qualitative graphs. Accordingly, this study analyzed the students' understanding revealed in solving the task of constructing qualitative graphs based on the level of covariational reasoning proposed by Carlson et al. (2002). As a result, this study confirmed differences in solving qualitative graph tasks depending on students' covariational reasoning level. In addition, In addition, this study suggests that the task of constructing qualitative graphs and interpreting them needs to be sufficiently addressed in the early stages of graph learning to confirm and develop students' covariational reasoning.
Preservice Mathematics Teachers’ Knowledge of Instruction Implementation Focused on Mathematical Competency
Authors:   The Korea Society Of Educational Studies In Mathematics, Hwang Yun Hee , Kim Sun Hee
Published: November 2024

As the direction of mathematics education was set to foster mathematical competency, implementing instruction that fostered mathematical competency became important. This study analyzed the teaching practices of preservice teachers and investigated KII of how teachers should carry out teaching to develop mathematical competency. Preservice teachers were found to have implemented the question to develop communication competency, student-centered classes, and guidance on mathematical competency evaluation, but their knowledge of providing feedback related to mathematical competency was found to be insufficient. Compared to the design of a course competency-centered class, the level of math competency intended did not match the instruction implementation. but when teachers implement sensitively to student responses, implementation is better than design. However, when conducting teacher-centered classes in which convergent questions were implemented and teachers answered questions on their own without paying attention to student competency or understanding processes, implementation is worse than design. This study closely analyzed the teaching practices of preservice teachers and showed in detail the characteristics that appear in instruction focused on mathematical competencies, and these cases can be examples that can promote changes in school classes. Since this study only focused on preservice teachers, it was suggested that the research contents need to be expanded to include in-service teacher and knowledge of understanding of students' competencies.
Research on Development and Application of Convergence Education Program Using Aperiodic Tiling
Authors:   The Korea Society Of Educational Studies In Mathematics, Lee Jeong-Yup , Heo Haeja
Published: November 2024

This study is a program development and application study to foster creativity and positive attitudes toward mathematics through tiling and mathematics. In school math, fourth graders in elementary school engage in regular pattern-making activities by pushing, flipping, and rotating flat shapes, and first graders in middle school cover interior angles of regular polygons. Practical Mathematics (2015 Curriculum), and Mathematics and Culture (2022 Curriculum), which are elective high school subjects, include tessellation activities. Tiling, also called tessellation, is commonly encountered in everyday life, such as in famous buildings like the Alhambra, as well as in home entrances, bathrooms, verandas, and squares. The works of artist Escher, who elevated such tiling into art, are widely known. Tiling is a convergence class subject which connects art and mathematics, and is a topic sufficient to stimulate students' curiosity and foster creativity. Recently there was a discovery of ‘aperiodic monotile’. Based on this discovery we raised following two questions: “We are planning to tile an infinitely wide bathroom floor. Are there tile shapes that can only tile the floor aperiodically?” and “We are planning to tile an infinitely wide bathroom floor. Is there a single tile shape that can only tile the floor aperiodically, when we only allow to use rotated versions and reflected versions of the tile?” Centered on these two questions, we developed a convergence education program and held a 10-session class for high school students. As a result, it was possible to see the possibility of increasing students' creativity and improving their positive attitude toward mathematics.
Comparative Analysis of Korean and American Textbooks on the Description Method of Integration by Substitution
Authors:   The Korea Society Of Educational Studies In Mathematics, Baek Seungju , Yi Gyuhee
Published: November 2024

This study sought to obtain implications for textbook writing and actual teaching and learning by analyzing the description methods of Korean and American textbooks on integration by substitution. Therefore, 8 types of calculus textbooks in Korea's 2015 revised curriculum and 2 types of American textbooks were analyzed according to the following perspectives: first, the characteristics of the overall structure, second, the connection between the components of the unit, and third, the acceptability of argument structure for theorem and problem solving. As a result of the study, first, there is a need to provide more explicit guidance on the roles and differences between the two theorems presented in the integration by substitution section of some Korean textbooks, and additional research was needed to determine in what order presenting these two theorems would be educationally effective. Second, there was a need to use a descriptive method that further revealed the connections between the components of the integration by substitution unit. Third, follow-up research is needed to investigate the educational effect between Korea's use of symbols for dx and dy and the American textbooks' view of them as differentials. The results of the study provide implications for writing, teaching and learning the integrals by substitution section of the textbook for the 2022 revised curriculum.
Analysis of Instrumentation Schemes for Elementary Geometry Tasks using AlgeoMath
Authors:   The Korea Society Of Educational Studies In Mathematics, Choi Mira , Lee Ye-Jin , Choi Eunmi , Choi Inyong
Published: November 2024

Recently, there has been increasing interest in the use of Dynamic Geometry Environments (DGE) in elementary geometry learning. This study aims to analyze elementary geometry tasks utilizing DGE from an instrumental perspective and to identify the conceptual and technical difficulties that elementary students may encounter. To achieve this, we analyzed textbooks and previous studies to extract tasks that utilize the Korean DGE, AlgeoMath, and conducted practical exercises to analyze the instrumentation schemes for each task. The analysis revealed that some terms and symbols of the tools were not aligned with the elementary curriculum or contained mathematical errors, and that some schemes requiring an understanding of functional perspectives or basic constructions in secondary mathematics could present conceptual and procedural difficulties for elementary students. Furthermore, we found that precisely implemented transformation tools were not suitable for the informal and intuitive learning of elementary plane figure movements. Finally, it was confirmed that the inherent characteristics of DGE, such as the independence and dependence of objects and the hiding feature, as well as the functional limitations and errors of AlgeoMath, could pose challenges for students. Based on these findings, the study suggests pedagogical implications for elementary mathematics lessons using AlgeoMath and provides insights into the functional composition of DGE for elementary use.
An Analysis of Fraction Operation Units from the Perspective of Semantic Alignment: Focusing on Semantic Relations and Quantity Types
Authors:   The Korea Society Of Educational Studies In Mathematics, Kim Nahee , Chang Hyewon
Published: November 2024

Mathematical concepts are derived from real-world situations, and their construction and application can be facilitated when real-world meanings and mathematical meanings are aligned. According to educational psychology research, the depth of interpretation and use of operations depend on whether the semantic relations between the objects presented in the problem situation and the potential mathematical relations are consistent. This study analyzed the semantic relations between objects in problem situations and the semantic alignment between the quantity types of objects and visual models in the fraction operation units of elementary school mathematics textbooks. The analysis revealed that, in problem situations, symmetric relationships were predominantly presented in fraction addition, subset-set relationships in fraction subtraction, and asymmetric relationships in fraction multiplication and division. Regarding quantity types, continuous quantities were presented more often than discrete ones, and in most cases, the quantity type of the object matched that of the visual model, though a few did not. Based on these findings, implications were drawn for selecting problem situations and instructional models that align with mathematical meanings and support student understanding from the perspective of mathematics learning psychology.

The structure and narrative style of textbooks are factors that directly affect students' mathematics learning and teachers' lesson plans. This study investigated how high school students use theorems in problem-solving and how they understand and use symbols in the integration by substitution section of textbooks to find out the relationship between the structure and narrative style of textbooks and students' mathematical problem-solving and use of symbols. First we examined students' ways of thinking through open-ended questionnaire responses, and then conducted interviews with some students. As a result of the study, first, students had various views on the symbol of ∫f(x)dx and the role of dx in it. Second, in solving problems in the integration by substitution section of the textbook, students did not use the  presented just before the problem. They responded that they did not use , and they reported that it would be confusing if  was used. Third in the integration by substitution, students sometimes used the symbol  dt/dx, as if dt and dx were separate quantities, similar to a division, and even though the students themselves used such calculation methods, they questioned the validity of the process. The results of this study will help teachers design lessons, reconstruct the curriculum, and write textbooks by showing students' perceptions of the structure and use of symbols in the integration by substitution section of the textbook.

In the late summer about 11,500 years ago, probably in the space of a few weeks, three young Paleoindian children died and were buried in a residential camp alongside Xasaa Na’ (Upward Sun River). An infant and neonate were buried together with associated funerary objects below a central cooking hearth, and later a ~three-year-old child was cremated and buried above the same feature. This article explores the lifeways of the Ancient Beringians that summer, reconstructed through zooarchaeology, stable isotope, spatial, and artifact analyses and implications of the mortuary treatment of these individuals with respect to the regional group, theDenali Complex, and early Paleoindian ideologies.

Authors: Beezley William H.
Published: November 2024

The World Today Series: Latin America offers the latest available economic, demographic, political, and cultural information. Including solid statistical data expressing freedom, violence, and governmental orientation. Consideration is given to the evolving relationships with the United States and other Latin American nations. Revisions have also addressed new historical interpretations, for example, of the history of Mexico and latest political changes, for example, in Venezuela and Cuba. Maps, charts, and photographs provide extensive visual expressions of the region, its geography, peoples, and cultures, in particular public architecture, agricultural technology, specular geology, and striking diversity. The images offer a narrative of the multiplicity of peoples as demonstrated in their clothing, economic and everyday activities, their physical surroundings. Consequently, the narrative combines global economics, national politics, and daily social life throughout the region. The chapters can be read as individual histories for each of the countries, within the context created by contrasts and similarities with the other nations of Latin America.
Sorgfaltspflichten von Geschäftsleitern beim Einsatz Künstlicher Intelligenz in der Unternehmensführung
Authors: Frey Nikolas
Published: November 2024

The remarkable advances in artificial intelligence (AI) are pushing for its use in the management of companies. For managers, however, the (non-)use of AI solutions can be associated with liability risks. This work sets out the legal framework for such use and examines the obligations for managers based on possible areas of application. Inter alia, the existing literature on delegation to employees and ISION case law are used as possible benchmarks and the effects on the business judgment rule are discussed.
Seele – Engel – Gott

Die Studie bietet einen ersten ordnenden Versuch, Meister Eckharts bisher kaum erforschte Rede vom Licht in seinen volkssprachlichen Predigten zu erfassen. Dank eines konsequenten close readings der volkssprachlichen Predigten Meister Eckharts wird das Motiv des Lichts nicht nur in seiner traditionsgeschichtlichen Bedeutsamkeit, sondern auch in seinen Funktionen für die homiletischen Kommunikationszusammenhänge wahrgenommen. So wird eine sensible Wahrnehmung Eckharts als Theologe und Denker in der christlichen Welt des frühen 14. Jahrhunderts ermöglicht.

Background. Designing the training of athletes should be based on specific goals and objectives at each stage of the long-term development. Each age stage in the development of an elite athlete has its own significance. The U23 competitions are organized to facilitate a smoother and more effective transition of wrestlers from junior to senior levels. The aim of the study is to determine the significance of performances in the U23 competitions for the subsequent development process of wrestlers. Materials and Methods. The following research methods have been used in the paper: the analysis of the scientific and methodological literature, the analysis of the official results, and methods of mathematical statistics. We have studied the sports careers of participants in the 2017, 2018, and 2019 World Championships in freestyle, Greco-Roman, and women's wrestling. A total of 1277 wrestlers’ sporting biographies have been analyzed. Results. The majority of participants (73.7 %) in the U23 age category competitions previously competed at the junior level. Moreover, more than half of the athletes (58.4 %) had prior experience of participating in cadet competitions. It is worth noting that 63.7 % of all wrestlers participated in senior-level competitions, and 31.5 % of them achieved podium finishes. Among women, a higher percentage of athletes continue their careers (46.3 %) and achieve success (20.1 %) on the international stage after the U23 competitions. For male freestyle wrestlers, the figures are lower, with only 38.2 % continuing their careers. Conclusion. The analysis demonstrated that the U23 competitions, which serve as a continuation of the cadet and junior age groups, are part of the overall sequence of competitions in the development of wrestlers at the international level. However, the importance of the U23 competitions varies depending on the level of athletes, and they serve both as preparatory and main competitions within the athletes' training system.
