Cascading Timers

A new method is proposed, called "cascading timers"; it solves the logical sequential problem that includes timers on its sequence; in automatic systems, this method solves in an analytical, didactic, systematic, and effective way. Most of the sequential systems of the industry include the time function into their logical sequence. This method can solve from simple problems where a single timer is applied to complex systems that use more timers, from single-loop problems to looping systems, including systems with multiple main lines and with external input signals. This method consists of staggering the timers of a sequential system and keeping the coils of the timers on until one cycle of operation is completed. When solving sequential systems based on the time function by analytical methods, there is the advantage that a reliable and standard solution can be reached without having accumulated years of practical experience. Application limits. The method is based on the timer on delay (TON). It applies to both types of logic, programming logic systems, using the PLC, and wired logic systems, called electromechanical control systems, which use all the devices physically in the equipment using relays. Do not apply to integrated circuits or generic array logic (GALs).

Integrated edge thresholded deep network for image denoising

The outcome of the denoising network suffers from over-smoothing effect, due to this, the texture content of the object will be lost. Lack of accurate texture properties in the image may lead to inefficient object segmentation and classification. This paper proposes an edge-preserving thresholding approach and applies it to the output of the denoised network. The thresholding approach relies on the distance and weight factors, which move the noisy components toward the mean of the subspace. This proposal is meant to treat over and under-smoothed components, where the smoothing decrement or increment is controlled by the threshold calculated with the average mean of the components in the respective subspace. The approach is compared with state-of-the-art methods in terms of image quality, and it is observed that this approach increases the quality proportionately. The result depicts that there is a significant improvement in PSNR of about 0.7~ 1 dB with the proposed integrated mechanism when compared against the conventional CNN-based image denoiser. Moreover, the edge details are better preserved with the proposed integrated mechanism.
A pattern-based approach to detect irony in twitter sentiment analysis

Twitter sentiment analysis poses challenges due to the informal language, limited character count, and prevalence of sarcasm, which can alter the polarity of messages. This paper presents a pattern-based approach to detect irony in Twitter sentiment analysis. By analyzing various types of irony and identifying their patterns, this paper proposes a methodology to improve the efficiency of sentiment analysis. Tweets are classified into different categories based on their sarcasm using a machine learning algorithm. The proposed approach involves feature extraction from tweets, including sentiment-related features, punctuation-related features, grammatical and phonetic features, and patternbased features. A hybrid pattern extraction with a classification model is employed to process tweet data and classify it as sarcastic or not. Experimental results demonstrate the effectiveness of the proposed approach in detecting sarcasm in tweets, with precision ranging from 84.6% to 98.1% across different classifier algorithms. This pattern-based approach offers promising results for enhancing sentiment analysis on Twitter and understanding the nuances of communication in social media discourse.
Samomesebi: Homage to the book by Marcus Aurelius thoughts in the education and upbringing of youth in the 21st century

In addition to each of us represents a piece of the puzzle Cosmos, all live and in its internal energy universe. We can call it vibrational field of Being. Only when we accept ourselves as a whole, as we are, then we can change. It is extremely difficult for young people to understand and accept. What are the consequences of ignoring mental plan of personality? Are there any shortcuts to make up for lost? What can be done? The answers to these questions, I tried to find in the thinking of the Roman emperor Marcus Aurelius. The most important detail of the whole of this work is to convey the message that every young man wonderfully gifted and capable human being has a unique purpose in life to be shared with the world.
The beginning of the development of teaching materials in the teaching of accounts in the younger grades of primary school

The need to count multi-digit numbers has encouraged people to design aids that can help them do so, and that make it easier for students to count today. The paper defines the concept of teaching aids, gives an overview of the beginnings of the development of teaching aids for arithmetic in different cultures and presents some old teaching aids used in Serbia in the late nineteenth and early twentieth century. The aim of this paper is to point out the basics of the development of teaching aids (teaching aids) in the teaching of arithmetic in the younger grades of primary school. The purpose of this paper is to acquaint teachers with the beginnings of the development of teaching aids for arithmetic and the possibilities of their application, in order to have a more diverse approach to students during the processing of teaching content about numbers and arithmetic. The review was done by historical and comparative method.
Model of work with practical examples of choir teaching at younger school age

Starting from the facts that show that choral singing provides multiple benefits in terms of general development of children, as well as that it is necessary to build a musically stimulating environment within primary school, the purpose of this paper is to present a model of working with choir made of the younger grades. Besides that, this paper provides concrete practical examples of choral teaching that will contribute to the better realization of the necessary elements of each choral work, such as audition, selection of compositions for work, methodical procedure of learning a new song, proper breathing, vocal warm-up and public performance. Each of these segments are very complex and demanding. We would like to emphasize that the model of working with the choir of the younger grades of primary school and its practical application, which we present, is the result of the content analysis provided by the previously consulted literature. The model provides concrete suggestions in working with pupils in choir classes. We believe that this work will be especially important for teachers who work, not only with the choir made of younger grades, but also with the class choir in order to discover new ways of artistic work. This model is just one of many possible aspects of the realization of choral teaching that relies on the recommendations discussed in the professional literature. We can expect the successful realization of the selected program only with a systematic and creative approach in choral work.
Functions of structural components in textbooks mathematics motivation for learning and metacognitive guidance

Mathematics textbooks have a long history while the study of mathematics textbooks has been developing. The aim of this paper is an overview of the general theoretical and methodological frames of mathematics textbook research. From a theoretical perspective, the sociocultural theory of development and education has gained attention in mathematics textbook research and in that theory textbooks are seen as a cultural-supportive tool. The focus is put on the concretization of cultural-supportive tools in mathematics textbooks through structural components with the function of learning motivation and metacognitive scaffolding. From the methodological aspect, the majority of textbook research refers to analysis, for that purpose, a protocol for monitoring the functions of structural components is proposed. On the other hand, there are fewer studies about textbook use by students, for that purpose, keeping a diary, interviews and observations are recommended. It is concluded that psychological constructs such as learning motivation and metacognitive scaffolding should be included in mathematics textbooks as support for self-regulation learning and problem-solving methods of teaching. These constructs are providing opportunities for holistic mathematics textbook research, from the perspective of textbook analysis and textbook use, which is recommended for future research.
Frequency of various forms of creativity in teaching Music Culture in primary school: 3rd and 4th grade

The aim of the paper was to present the significance and various forms of music creativity and to determine how often the forms of music creativity, which teachers encourage in the Music Culture classes in the 3rd and 4th grade of the primary school, are represented. We examined how often the following types of creativity are represented: improvised movement accompanied by music, making illustrations while listening instrumental or singing musical example, conceiving lyrics on a well-known melody, conceiving a melody on the lyrics of the poet; making melody and lyrics of songs and creating rhythmic escort and arrangements for performing on rhythmic instruments on a chant/song/musical play. The sample of the research consisted of 74 teachers. A descriptive method is applied. The results of the research showed that in the future more work should be done on the music literacy of pupils, since it is a prerequisite for work on more demanding forms of musical creation. In the area of children's music creativity in 3rd and 4th grade, it is necessary to find a way to encourage teachers to focus on more complex types of music creativity, such as creating melody on poetry texts, making both melody and song lyrics.
The development of the sociology of education as a scientific and study discipline

The paper presents an overview of the historical development of Sociology of Education in the world and in our region, as well as its constitution as a scientific and study discipline. When studying the material for writing this paper, it was concluded that there is little recent literature that addresses the subject of historical background to this subject. The relationship of sociology of education with other sociological disciplines, as well as with general sociology, is also emphasized. We place particular emphasis on books and papers dealing with the constitution of the sociology of education and its inclusion in the curricula in the world and in our country. Only some of the works that are crucial for a chronological understanding of the development of this sociological discipline in the world and in the area of the former Yugoslavia are listed.
Stimulation of early literacy development

In this paper we will discuss the possibilities for the systematic stimulation of early literacy development. Listening to adult reading and make-believe reading are the children's first pre-reading activities, and these activities influence the actualization of other people's speech in children's minds. The first global reading, observation, and creation of rhymes, as well as intuitive comprehension of the syllable in a song or a counting rhyme are the outset of the children's ability to manipulate linguistic units and principles of the symbolic representation. The aspirations towards the mental and visual manipulation of linguistic units help them form the appropriate pre-literary predispositions. The next level of encouragement will imply the introduction of the following terms: sentence, word, sound and letter. With such bases, it will be possible to train children to perform word analysis and synthesis, the symbolic representations of linguistic units, until the final introduction into the world of literacy.

Field Trip Learning Method to Improve the Ability of Writing Descriptive Paragraph in Elementary School Students

Students from elementary school are expected to have good language skills because language is the most critical human capital. Speaking is an act carried out by every human being in togetherness with other humans to communicate. Language as a means of communication can be in the form of spoken language or written language. This research aims to analyze the effectiveness of the field trip method on elementary school student's ability to write descriptive paragraphs. The research carried out in this research is quantitative research. The method used in the research was quasi-experimental with a nonequivalent research design (pretest and posttest) control group design. The research sample consisted of 62 students consisting of 31 class IIIA students as the control class and 31 class IIIB students as the experimental class. Data was collected using test sheets to determine student learning outcomes. The data analysis used was a t-test analysis with a significance level of 5%. The research results show significant effectiveness in the ability to write descriptive paragraphs. Field trips for elementary school children can be used to expand the information obtained in class, providing experience regarding existing realities. Thus, the field trip method is effectively used to learn to write descriptive paragraphs and can be a solution for teachers experiencing similar learning obstacles.
The Implementation TPACK in Elementary School

Industrial Revolution 4.0 requires teachers to master technology to be integrated into learning. This research aims to analyze the application of Technology, Pedagogy, and Content Knowledge (TPACK) in the post-online learning process. This research is classified as descriptive qualitative research using mixed methods with a sequential exploratory strategy. The subjects involved in this research were 20 class teachers. The data collection used in this research is data collection through interviews, observation, and documentation. The instrument used to collect data for this research is a questionnaire. The data obtained from this research will be analyzed using inductive model analysis techniques. The research results show that in implementing TPACK, many teachers, especially older ones, still need help operating technology well. Apart from that, teachers have yet to be able to utilize technology to create new representations. The teacher only provides learning content based on students' books and several examples from Google and YouTube. Therefore, teachers need to understand aspects of TPACK. This research implies that all stakeholders will be able to realize the importance of ICT because using learning media using technology aims to develop a curriculum in schools to improve the quality of education.
Differentiated Learning Number Division Material Increases Elementary School Students' Interest and Learning Outcomes

Students' low interest and learning outcomes in learning mathematics are due to the need for more application of varied learning models, so in the learning process, students are more unfocused. The research aims to analyze the effect of differentiated learning on the interests and learning outcomes of fourth-grade elementary school students. This research is classified as experimental with a non-equivalent control group design. The subjects involved in this research were fourth-grade elementary school students. Data collection in this research was carried out using observation, interviews, questionnaires, and tests. Data regarding learning interest is collected using a questionnaire, and learning outcomes are measured using multiple-choice tests and essays. The data obtained in this research was then analyzed using the multivariate analysis technique analysis of variance (Manova). The results of the data analysis show that the first hypothesis, namely the null hypothesis, is rejected, and the alternative hypothesis is accepted. Next, the second hypothesis, namely the null hypothesis, is rejected, and the alternative hypothesis is accepted. The calculated F significance number is less than 0.05 in the third hypothesis, so the null hypothesis is rejected, and Ha is accepted. Based on these results, differentiated learning positively influences the interest and learning outcomes of fourth-grade elementary school students in learning mathematics. Differentiated learning can increase fourth-grade elementary school students' interest and learning outcomes.
