Analysis of new-onset seizures following use of COVID-19 vaccinations in children based on VAERS

ABSTRACT Background Recently, there have been some reports of seizures related with COVID-19 vaccinations. However, no studies have systematically investigated the relationship between seizures and various COVID-19 vaccines. Research design and methods This research aimed to analyze the characteristics and risk signals of new-onset seizures in children caused by various COVID-19 vaccines based on the data of the Vaccine Adverse Event Reporting System (VAERS). To identify potential risk signals, a disproportionality analysis was conducted. The reporting odds ratio (ROR) and the Proportional Reporting Ratio (PRR) were used to detect signals. Results A total of 695 children with new-onset seizures events associated with COVID-19 vaccinations were retrieved from the VAERS database. Compared with influenza vaccinations, the percentage and rate of COVID-19 vaccinations related seizures was all reduced. The median onset time of seizures was 1 day after COVID-19 vaccines. No signal was detected for an association between the COVID-19 vaccines and new-onset seizures, neither when compared with influenza vaccines nor with non-COVID-19 vaccines. Conclusion No statistically significant risk signal of COVID-19 vaccine-related seizures was found in this study. However, it is still necessary to monitor the possibility of new-onset seizures when children are immunized with COVID-19 vaccines.

Long-term safety of lanthanum carbonate in the real word: a 19-year disproportionality analysis from the FDA Adverse Event Reporting System

Background Lanthanum carbonate is widely used to manage serum phosphate and calcium levels in end-stage kidney disease (ESKD) patients, yet comprehensive long-term safety data are lacking. This study leverages the FDA Adverse Event Reporting System (FAERS) to assess the extended safety profile of lanthanum carbonate. Research design and methods We analyzed FAERS data (2004-2022) to study the association between lanthanum carbonate and adverse events (AEs). Using MedDRA v25.0, we identified risk signals through System Organ Classes (SOCs) and Preferred Terms (PTs). Disproportionality analyses quantified lanthanum carbonate-associated AE signals. Results Among 3,284 reports, 2,466 were primary suspected AEs linked to lanthanum carbonate. Males reported AEs more frequently than females. Patients aged over 64 represented the majority. Median onset time for lanthanum carbonate-related AEs was 146 days. Gastrointestinal disorders were prevalent. We identified 16 new signals, including stress, abnormal hepatic function, cholelithiasis, bile duct stone, gastric cancer, and adenocarcinoma gastric. Stress was notable, particularly in male patients over 65 and those with lower weight. Conclusions This study affirms lanthanum carbonate’s long-term safety for reducing elevated blood phosphorus levels. While gastrointestinal disorders were common, attention must focus on emerging AEs, particularly stress, especially in elderly patients.

The effect of character-charged maritime textbooks on increasing students’ character values

<span lang="EN-US">Teaching and learning activities for early childhood students currently do not support increasing the character values of graduates, and the emphasis is still on learning whose output leads to competency according to standards. Using character-charged maritime textbooks is a solution to assist teachers in facilitating the application of character values in marine learning. The purpose of this research is to evaluate the impact of character-focused marine textbooks on students’ moral development. The method of research is quasi-experimental, with a pretest-posttest design. The sampling technique is convenience sampling. Two classes use the method, B1 for experimental purposes (with 80 students) and B2 for comparison (with 80 students). Independent T-tests were used in data analysis to compare differences in students’ average scores in the experimental and control groups before the intervention. N-Gain was used to compare the character growth of control and intervention students. The study’s findings indicate that students’ character values significantly influence adoption of morally edifying maritime textbooks. This shows increased student character values, namely responsibility, honesty, discipline, love and affection, caring, courage, independence, and hard work, after being taught using character-charged maritime textbooks. Thus, it can be concluded that character-charged maritime textbooks can significantly increase students’ character values.</span>

Conclusion: The application of tera exercise can reduce the problem of acute pain nursing in elderly families with hypertension.

Art and Cultural Diversity of Dayak Ngaju Tribe: Christian Education Interactive Learning on Kuala Kurun

The prevalence of comedy and satirical programming on television and online platforms has contributed to a growing divide between entertainers (musicians) and their audiences, with the former offering guidance, criticism, and a reflection of everyday life through their work. As far as the researchers's search and exploration, there are still a few who examine and can even be said to rarely relate music through the culture of Karungut and Deder song, a culture that exists and lives in Dayak Ngaju, Central Kalimantan. This research is interesting because besides music as a fun strategy, Deder song as local wisdom is an expression of the daily life of the Dayak people in Central Kalimantan. This song contains advice, satire, advice and is still present today as part of the richness of world civilization. Lantunan Deder is presented in traditional events (weddings, welcoming guests and various Manasai dances that include men and women in rhythm or balance). Participation in Lantunan Deder has become interesting as a strategy for learning about the content of Christian religious education lessons in schools, living rooms and churches. The usefulness is more about the love of culture, God also sensitizes the participation of women and men as part of the sustainable development goals (SGDs). The research method used 4D model development with analysis and validation space and considered diversity, and song structure. The results showed that Deder as method, strategy, development, cultural actualization, as well as an instrument rarely done in the learning process of Christian religious education and researchers conducted direct practice in the field by melting Deder chants with the learning process which resulted in the creativity of students as actors and user subjects as well as cultural preservation subjects for Ngaju Dayak culture.

Education transformation in Indonesia requires the implementation of differentiated learning

This study describes teachers’ perceptions of implementing education transformation after the Corona Virus Disease 2019 (COVID-19) pandemic. The research method uses a mixed-method approach: quantitative and qualitative. Quantitative data collection using questionnaires. Analysis of quantitative data using the Rasch model. Qualitative data analysis through the collection, reduction, and presentation. The respondents of this research are 389 teachers in Indonesia. The questionnaire instrument contains 21 items of statements. Before being sent to teachers via the Google form, the questionnaire had met the readability test by 10 teachers. This research found that the most effortless education transformation is related to the education ecosystem. However, implementations still challenging to implement are related to pedagogy, especially the implementation of differentiated learning. Therefore, this study implies that the educational ecosystem needs to be maintained. Meanwhile, pedagogics, especially those related to differentiated learning, must be improved with various training to recognize student learning styles, multiple intelligences, learning readiness, teacher socio-emotional, and student socio-cultural.

The Role of Gunawan Setiawan's Batik Industry in the Education Process and Maintaining Batik Cultural Symbols in the Community

Batik is one of the handicrafts that has high artistic value which has been passed down from generation to generation by the ancestors of the Indonesian nation since the Majapahit Kingdom and continues to be preserved today. However, we have discovered the reality that currently there are still many people who do not fully understand the meaning or philosophy behind batik motifs. Through this, it is necessary to have an educational process for the community, one of which can be carried out by the batik industry. The purpose of this study is to provide an overview regarding how the educational process carried out by Kampung Batik Kauman, especially Batik Gunawan Setiawan, is to provide a comprehensive understanding of batik to the public. This research was conducted in Surakarta, namely in Kauman Batik Village, precisely in Gunawan Setiawan Batik. The research method used is a qualitative research method with a case study approach. The results showed that there were several educational processes carried out by Batik Gunawan Setiawan, such as creating a batik gallery, conducting batik exhibitions and holding batik training. Furthermore, the process of batik education in the community is analyzed using Structural-Functional Theory - Radcliffe Brown as a countermeasure to tensions. As he stated that culture is not to satisfy individuals but to fulfill the social structure of society and emerge to overcome tensions such as theft of cultural identity due to the lack of public concern regarding local culture.

The combination of the Internet and computers has resulted in many new products, including smart homes. The emergence of smart homes can satisfy people's detection of the internal environment of the home, not only to ensure the continuity and safety of indoor monitoring, but also to provide convenience for people to manage their family life. This paper analyzes the current status of smart home research at home and abroad, and people's needs for homes, and builds and designs smart home systems based on Ethernet and ZigBee protocol wireless sensor networks connected to TCP/IP protocol. In this article, the ARM chip is used in the Android system to ensure that the system and functions are matched, and information is transmitted through the serial port of the development board. After receiving the corresponding sending signal, the wireless module will use ZigBee technology to send the corresponding signal to achieve the goal of controlling home appliances. We divides the control system into two parts, the Android Voice Control Plateform and the data collection terminal. The former is based on the Android operating system and is designed for voice recognition control; the latter uses a ZigBee microcontroller to achieve control and feedback. This article uses the built-in voice control system of the smart home to subtly replace the conventional control method of the smart home. Moreover, the dialogue with users is very high, easy to use, low cost, and very practical. In addition, the research methods used in this article can also be applied to other related fields.

Xác định acetamiprid bằng phương pháp quang học sử dụng dung dịch nano vàng được ổn định bằng Polydiallyldimethylammoni clorua

On this research, the development of a simple, cost-efective and highly sensitive spectrophotometric method for acetamiprid detection based on the localized surface plasmon resonance of polydiallyldimethylammonium chloridestabilized gold nanoparticles. By naked eyes, one can detect acetamiprid by the visual change of gold solution color from red to purple, corresponding to the shift of maximum absorbance wavelength in the UV-Vis spectrum. Quantification of acetamiprid is possible through a linear relationship between the maximum absorbance wavelength and the acetamiprid concentrations in the range of 8×10-8 -2×10-6 M. Under the optimum conditions including pH 5, NaCl concentration of 0.02 M and incubation time 20 min, the present method has high precision (RSD < 5%), very low limit of detection (LOD) of 2.7×10-8 M, limit of quantification (LOQ) of 8.2×10-8 M. This method has been successfully applied to determine acetamiprid in several pesticide samples and vegetable samples. The measurement results of acetamiprid in the pesticide samples of the research method with the HPLC-UV method showed a difference of < 2%, while for the vegetable sample, the difference between the research method and the LC-MS/method method/ MS < 5% shows that the method has high accuracy and reliability.

Developing technological pedagogical content knowledge skills during teaching practicum

<span lang="EN-US">This study investigates the efforts of Indonesian pre-service teachers in developing their technological pedagogical content knowledge (TPACK) skills during teaching practicum, explores the obstacles they encounter in this process, and examines their responses to the challenges of TPACK skills development. Employing qualitative narrative inquiry as the research method, the study interviews five pre-service teachers from various study programs to gain insights into their experiences. The findings demonstrate that Indonesian pre-service teachers employ diverse strategies to enhance their TPACK skills, including observing experienced teachers, participating in workshops or online courses, reading relevant literature on TPACK, and consistently integrating TPACK into their teaching practice. However, they face obstacles such as a lack of confidence in their teaching abilities, limited time and resources for reflective practice, and inadequate self-awareness regarding their skills. To overcome these obstacles, they respond by collaborating with peers and mentors, engaging in reflective teaching practice, and setting goals for each practicum session. The study provides valuable insights for teacher training institutions (TTIs), educators, practitioners, and policymakers, facilitating the implementation of more effective strategies for integrating TPACK in future events.</span>

A construção da sociedade neoliberal brasileira: qual o lugar da democracia?

Abstract The paper aims to analyze how democracy is structured within the neoliberal capitalist system in the Brazilian context. While neoliberalism requires market liberalization, reduction of the social state, and financialization of life, democracy presupposes political and economic equality, public apparatus, and inclusion; thus, it is necessary to discuss this conflicting relationship. The first session of the work discusses the economic, political, and social system of neoliberalism, understanding its requirements and characteristics, as opposed to democratic pretensions, to enter into Brazilian particularities. The second topic analyzes the construction of a neoliberal society in the country, establishing the investigation through the clash between social development and neoliberal advancement in Brazil. Finally, it examines the presence of neoliberal capitalism from the Partido dos Trabalhadores (PT) governments to the first two years of the Bolsonaro government, questioning the place of democracy. For this, the research used the deductive approach method and type of bibliographical and documentary research with a qualitative approach. In conclusion, we highlight the obstacle that neoliberalism imposes to realize a substantial, egalitarian, and plural democracy, marginalizing its power and restricting it to the electoral sphere.

Analysis of causes and factors of the spread of takfirism in Kazakhstan

The purpose of this research is to analyse the emergence of takfirism, its spread and its evolution in contemporary Kazakh society. The methodological foundation of the study was provided by general theoretical methods of scientific cognition, and various methods of collecting and systematising information. Among the general scientific methods are the method of theoretical analysis; the historical method of comparing individual religious movements of different periods in Kazakhstan, and the specific scientific and philosophical-religious methods of research. The results have suggested that unfounded takfirism poses a threat to the sustainability of diverse communities in Kazakhstan. The religious, ideological and theological preconditions for takfirism in Kazakhstan were analysed. Noted the diversity of approaches by Muslim scholars to understanding and interpreting the ayats of the Qur'an. Presented aspects of distortion in interpreting the essence of Shariah texts. Noted that the influence of political and social factors is significant. Focuses on some of the socio- psychological aspects of the development of radical attitudes among young people. The qualities inherent in young people that enable them to resist external non-ideological attacks are identified. Illiteracy, poor quality of education and the low culture of some people in Muslim countries are among the key elements. It was noted that the main factor in takfirism in Kazakhstan is the influence of the Salafi-Wahhabi movement. The practical significance of the study is that its content is of interest in developing the worldview of contemporary young people in the Republic of Kazakhstan. The results can be used as a teaching and practical material for students and researchers on contemporary history and religion in Kazakhstan.

A study on determining the views of people on the COVID-19 vaccine

The aim of this study was to determine the views and approaches of the public to the COVID-19 vaccination in Turkey. We conducted a descriptive study using the data collection method which is among quantitative research methods and the screening technic for analysis. The data collection method for the study was an online survey. The 38.4% of participants stated they would consider getting vaccinated, 50.6% stated they were undecided, and 11% stated they would not consider getting vaccinated. There was also a significant correlation between the participants' desire to be vaccinated and their educational level, age, and socioeconomic status. The belief that being diagnosed with COVID-19 creates stigmatization/labeling in society, as well as the belief that the vaccine will have serious side effects, reduce the possibility of getting vaccinated. The study also found that there is a positive correlation between the belief that the vaccine can defeat the virus and the possibility of getting vaccinated. Understanding the causes and effects of vaccine hesitancy and rejection is essential for developing effective immunization programs. Policy makers should inform the public to increase the trust in the vaccine and dispel the misinformation and rumors about COVID-19.

NUMERICAL TREATMENT OF LINEAR VOLTERRA INTEGRO DIFFERENTIAL EQUATIONS USING VARIATIONAL ITERATION ALGORITHM WITH COLLOCATION

To numerically solve the linear Volterra integro-differential equation, this study employs fourth-kind Chebyshev polynomials and the variational iteration algorithm with collocation, which is a combination of the variational iteration strategy and collocation technique. By applying fourth-kind Chebyshev polynomials to the variational iteration method with collocation for solving Volterra integro-differential equations, mathematical problems with a broad range of multidisciplinary applications are addressed, and numerical techniques that produce more accurate and efficient results are developed. The recommended method is then used, and the fourth-kind Chebyshev polynomials generated for the given integro-differential equation serve as the trial functions for the approximation. As a result, the suggested method's significance probably goes beyond a particular equation or application, as it contributes to the larger field of mathematical modeling and numerical analysis. Research methods employing a variational iteration algorithm with collocation aim to provide general techniques that can be applied to a wide range of problems. Additionally, numerical examples were provided to highlight the applicability and dependability of the proposed methodology. The mathematical computations were carried out using the Maple 18 software.

Post Covid-19 pandemic analysis offline classes versus online classes: Conflicts in early childhood education in Indonesia during the Covid-19 pandemic

Early childhood education in Indonesia is an area that parents are beginning to show interest in for preparing their children to progress to the next stage of education. The learning process involves selfdevelopment, cognitive training, emotional training, psychomotor training, and social interaction training, fostering independence in children during their playtime. Early childhood education differs from other levels as it emphasizes play while still incorporating learning. However, the onset of the Covid-19 pandemic in early 2019 has significantly impacted early childhood education, leading to the implementation of online classes. This change has affected not only students, who are in an age group susceptible to the disease, but also young children who may struggle to grasp the meaning of the Covid19 virus, unlike adults. Research objectives: a. To analyze early childhood responses to online learning. b. To investigate the impact of online teaching and learning activities on early childhood education in Indonesia. Utilizing qualitative research methods, this study is described through descriptive analysis based on a literature review and an examination of social phenomena. Children experience psychological shock when transitioning to home-based learning, missing the presence of teachers and friends, resulting in boredom and a lack of motivation to complete assignments. This psychological impact extends to parents, particularly mothers, who now have the responsibility of teaching their children at home, a role previously handled by teachers at school. Online classes are considered the optimal solution to curb the spread of Covid-19 in early childhood environments. The conflict between online and offline classes in the realm of early childhood education forms the basis of this research article.

Adaptation and validation the integration scale for Indonesian university students: academic and social

Student integration is a student’s ability to integrate into the social and academic systems of the university. Integration of students has been shown to affect how well they do on campus, which helps them finish higher education. The integration scale (IS) measures integration ability that meets the principle of simplicity. The integration scale is formed of 16 items divided into five aspects and two factors. This study aimed to adapt and validate IS instruments for the Indonesian university student population. The research methods complied with the six-step procedures the International Test Commission set out. A total of 309 participants were undergraduate students. They were between 17 and 23 years old (mean=19.42, SD=1.11 years), with 247 females (79.94%) and 62 males (20.06%). The results of the confirmatory factor analysis revealed that a total of 16 items were valid and reliable. Three models that have acceptable fits were confirmed. The results demonstrate that the Indonesian integration scale measures undergraduate student integration with comparable precision to the original scale. This scale can identify students who require academic and social integration assistance and evaluate the institution’s role in academic development.

Effect of perineal massage and gentle techniques on perineal rupture in primigravida maternity mothers

Background: Perineal rupture is a tear that occurs when a baby is born, either spontaneously or by using tools/actions. Preventive efforts can be made to reduce the risk of perineal rupture by massaging the perineum and using good pressure techniques during labor. Objective: To determine the effect of perineal massage techniques and pressure on perineal rupture in primigravida mothers who give birth. Method: This research uses experimental research methods; this type of research is quantitative with a pretest-posttest research design with a control group and an analytical study design with a retrospective approach. The total research sample required was 30 primigravidas, with details, namely 15 people from the perineal massage group and 15 from the gentle technique. Sampling was taken using an accidental sampling technique, where subjects were selected as research samples based on cases/respondents who happened to be available in a place according to the context. Results: research results of primigravid mothers who experienced perineal rupture in the perineal massage group were two people (20%), and in the menstrual technique group, there were eight people (80%), based on the results of data analysis using the Wilcoxon test, the p-value was obtained. In the perineal massage group, it was 0.000; in the gentle technique group, it was 0.005. Conclusion: It can be concluded that perineal massage is more effective than gentle techniques in preventing perineal rupture in primigravida mothers. To ensure the effectiveness of the chosen method, it is advisable to consult with medical personnel experienced in this field and follow the recommendations and protocols approved by the relevant health authorities. In addition, careful monitoring and care during labor is also essential to minimize the risk of perineal rupture.
