Dynamic Range of a Digital Radio Receiver with a Photonic Analog-to-Digital Converter
Authors: Denisov A.E. , Danilaev D.P.
Published: January 2024

The article is devoted to determining the requirements for the preliminary, analog part of the receiver and its structure when using a photonic ADC. The subject of research in this case is the issues of ensuring a large dynamic range of signals at the input of a receiver with a photonic ADC. The parameters and properties of the PADC with optical quantization and discretization are investigated. The distinctive features of the PADC are a high sampling rate, about 100 GHz, the possibility of increasing the carrier-to-noise ratio (CNR) and the effective number of bits (ENOB) due to the amplification of the carrier or modulating signal, and a low noise factor of microwave photonic elements. The presented advantages make it possible to reduce the structure of the analog part of the receiver by eliminating the mixer and anti-aliasing filter, as well as to achieve better sensitivity due to a lower level of internal noise. The study also revealed a limitation of the dynamic range imposed by the photonic element base. The reason for the limitation is the nonlinearity of the electro-optical modulators used and the limitation of the upper limit of the dynamic range to the photodetectors used. All this leads to requirements under which the analog part must provide significant amplification of the received radio signal, as well as the implementation of a variable gain. As a result, structural solutions are presented in the form of multichannel switching circuits. The principle of operation lies in the fact that each channel, consisting of a cascade of linear amplifiers and a PADC, has a different gain, and in the digital processing unit, channels are compared and switched depending on the signal level. At the same time, the level should be in the 'corridor' of acceptable values for the application of the PADC and within the dynamic range. The presented structural solutions will make it possible to implement radio receivers capable of receiving and processing a microwave signal without transferring the signal to an intermediate frequency. At the same time, the required signal amplification level of 105 - 106 can be achieved, which makes it possible to achieve a signal level of 2.5-9.5 V, at which the photonic analog-to-digital converter has the best CNR and ENOB indicators.

Authors: Verma Sony , Kumar Anil , Gupta A. K.
Published: January 2024

Abstract: In this paper, speed control of induction motor using fuzzy logic controller is proposed. Speed control of induction motor takes place by, Direct torque control(DTC) method i.e. by directly controlling torque. Here we have used Voltage/Frequency speed control method of induction motor. The fuzzy logic controller (FLC) solves the problem of non linearity’s and parameter variation of induction motor. Unlike the conventional standard controllers, the proposed controller has much less computationally demanding. Direct torque control scheme of induction motor is firstly used. Then, the specified rule and their membership functions of proposed fuzzy logic system will be represented. The performance of a controller is evaluated under various operating conditions. A simplified FLC with relatively fewer rules will be implemented for perfect speed control.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Han Young-In , Yang Young-Ok
Published: January 2024

Objectives This study is to assess the level of clinical reasoning skills of nursing students who are in the initial stages of learning clinical reasoning abilities, and to analyze the impact on these skills using quantitative and qual-itative research methods.
Methods A mixed methods research approach was utilized. Quantitative data were collected using self-administered questionnaires from 163 nursing college students in Kimhae City. Qualitative data were collected through focus group interviews with 12 participants. The data were analyzed using a convergent design model.
Results The quantitative analysis revealed that grades (β=.215, p=.003), major satisfaction (β=.163, p=.021), and critical thinking disposition (β=.593, p=<.001) significantly influenced clinical reasoning competency, explaining 47.0% of the variance (F=18.826, p=<.001, Adj R2=.470). The qualitative analysis indicated that students faced dif-ficulties due to lack of nursing knowledge and inadequate understanding of patient situations.
Conclusions Educational programs aimed at enhancing clinical reasoning competency should include various methods such as presenting scenarios related to patient situations and teaching students how to search for rele-vant information, to facilitate students' understanding.

Published: January 2024

Objectives The purpose of this study is to compare and analyze the meaning and method of ellipse construction of the ｢Geometry｣ and ｢Earth ScienceⅡ｣ textbooks of the 2015 revised curriculum.
Methods To do this, an analysis framework for the meaning and method of ellipse construction was developed, and the contents related to ellipse construction of seven ｢Geometry｣ textbooks and four ｢Earth ScienceⅡ｣ text-books were analyzed in accordance with the analysis framework.
Results First, seven ｢Geometry｣ textbooks and four ｢Earth ScienceⅡ｣ textbooks all suggested activities to mean drawing ellipse. Second, five ｢Geometry｣ textbooks presented the activity of constructing an ellipse using ruler and compass. Third, in the case of the ｢Geometry｣ textbooks, four presented a method of drawing using concen-tric circles, four presented a method of using origami, and five presented a method of drawing using pushpin and thread. Fourth, the same ellipse drawing activity was presented in the four ｢Earth Science Ⅱ｣ textbooks. All text-books presented activities to draw the elliptical orbit of Mars based on observation data, and methods of drawing using pushpin and thread.
Conclusions Since the link between science, mathematics, information, and environmental curriculum is em-phasized, it is necessary to conduct a follow-up study on the curriculum linking mathematics and science based on the results obtained in this study. In addition, research on how to use mathematical technologies in science education has recently been conducted, so follow-up research on various teaching and learning method to con-struct an ellipse orbit such as using mathematical technologies, needs to be conducted in the ｢Earth ScienceⅡ｣ textbook.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Yang YiJin , Maeng HeeJu
Published: January 2024

Objectives This study examined the appropriateness of using an intelligence test paper for a simple intelligence test of gifted elementary school students through a correlation analysis between Wechsler intelligence scale for children(K-WISC-Ⅴ) and korean kaufman brief intelligence test(KBIT2).
Methods For the study, an intelligence test was conducted on 36 elementary school students in Gyeonggi Province who applied to participate in an intelligence test using the K-WISC-Ⅴ and the KBIT2 for two months from January to February 2021. Statistical analysis was performed on the collected data using Pearson's simple correlation analysis method using the SPSS statistical program.
Results First, there was a statistically significant correlation (r=0.823) between the total intelligence quotient of K-WISC-Ⅴ and KBIT2. As a result of the correlation analysis of intelligence quotient by indicator, KBIT2 verbal ability was found to have a statistically significant correlation in the order of language comprehension, working memory, fluid reasoning, and space-time of K-WISC-Ⅴ, and no correlation was found with language ability be-cause processing speed had different characteristics. As a result of the correlation analysis of intelligence quo-tient by indicator, KBIT2 verbal ability was found to have a statistically significant correlation in the order of lan-guage comprehension, working memory, fluid reasoning, and space-time of K-WISC-Ⅴ, and it was not found no correlation with language ability because processing speed had different characteristics.
Conclusions Therefore, it was confirmed that KBIT2 can be used as a simple intelligence test tool instead of K-WISC-Ⅴ, which is generally used to check the intellectual level of gifted students in elementary school.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Sim Hyegyeong , Park Youngmin
Published: January 2024

Objectives The purpose of this research is to examine the variation in reading comprehension concerning the pro-vision of cues that enhance the perception of key content words.
Methods In this study, middle school students were categorized into two groups based on the provision of cogni-tive cues for key content words. Following this categorization, reading comprehension tests were administered to each group under varying cue provision conditions. At this juncture, cognitive cues were designated by employ-ing the font style corresponding to key content words. Study participants engaged in reading explanatory texts under different cognitive cue conditions, subsequently undergoing a recall-based reading comprehension test. The collected reading comprehension test results were subsequently analyzed using effect size measures.
Results The group in Condition 1, which did not receive cognitive cues for key content words, demonstrated an improvement in the average reading comprehension test results. On the other hand, the group in Condition 2, which was provided with cognitive cues for key content words, exhibited a decline in their average reading com-prehension test results. Both conditions experienced a decrease in the average scores among the upper-level group, but the decline was more pronounced in Condition 2's upper-level group. Furthermore, both conditions ob-served an enhancement in the average scores of the lower-level group, with Condition 2's lower-level group showing a more substantial improvement.
Conclusions Providing cognitive cues for key content words may enhance reading comprehension for the low-er-level group, but it could disperse attention and hinder reading fluency for the upper-level group.

Published: January 2024

Objectives This study aimed to verify the mediating effects of emotional self-disclosure in the process of covert narcissism and romantic relationship satisfaction.
Methods The Actor-Partner Interdependence Model was used to examine these associations in 140 couples cur-rently in a relationship. Since couples are interactive relationships that interact with each other, this study was conducted by Kenny’s Actor-Partner Interdependence Model(APIM).
Results The results showed that, first, female had a higher level of covert narcissism and emotional self-dis-closure than male, who had greater romantic relationship satisfaction than female. These findings confirm gender differences in the variables. Secondly, covert narcissism had actor effects on romantic relationship satisfaction and self-disclosure of positive emotions both in male and female. Male's covert narcissism and self-disclosure of positive emotions had partner effects on female's romantic relationship satisfaction. Finally, Female's covert narcissism had actor effects on their romantic relationship satisfaction via self-disclosure of negative emotions. Female's covert narcissism also had partner effects on male's romantic relationship satisfaction.
Conclusions The implications of this study were discussed in connection with the results of previous studies, and implications and suggestions for follow-up research were made to effectively help clients with covert narcissism in the counseling field.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Lee Yun Jung , Paik Young Suk , Oh Hyun Suk
Published: January 2024

Objectives The purpose of this study is to analyze teacher-child interaction as a mediating variable, with children's peer play interaction as an independent variable, which affects children's positive-prosocial behavior.
Methods Relationships and influences between variables related to children's peer play interaction, children's positive and pro-social behavior, and teacher-child interaction were examined among 174 preschool teachers and 498 5-year-old children from kindergartens and daycare centers in G City and J Province. To confirm, a survey was conducted and the collected data were analyzed for mediation effect using PASW 24.0.
Results As a result of confirming the research results, it was confirmed that there was a significant correlation between the first independent variable, children's peer play interaction, the mediating variable, teacher-child interaction, and the dependent variable, children's positive-prosocial behavior.
Conclusions Although children's peer play interaction is a meaningful variable that affects children's positiveprosocial behavior, it can be predicted that it will have a more meaningful impact when teacher-child interaction is added. This suggests that re-education is needed to promote teacher-infant interaction that can be directly used in actual educational settings to improve the quality of children's peer play interactions and children's positive-prosocial behavior.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Choi So-Jeong , Kim Kwihoon
Published: January 2024

Objectives This study was conducted to analyze the types and causes of the digital information gap among low- income students, identify prerequisites for resolving the digital information gap, and derive implications to help with subsequent research related to this.
Methods Using the digital information gap survey data collected by the Korea Intelligence Information Society Promotion Agency in 2021, a factor analysis of 22 questions was conducted to determine the types of digital information gap, and a step-by-step selection method was used to analyze the causes of each type of digital information gap. Multiple regression analysis was performed using.
Results The average monthly household income of low-income students was analyzed to affect the access gap. In addition, it was found that the older the age, the higher the ability to use PCs and mobile devices, and the higher the household average monthly income, the relatively higher the ability to use PCs and mobile devices. On the other hand, it was found that women were less capable of using PCs. Additionally, students with a positive attitude toward digital technology say they are familiar with the basic functions of digital devices, and the efficacy of using digital devices appears to have an impact on the gap in use of low-income students.
Conclusions The types of digital information gap among low-income students were classified into ‘access gap’, ‘use gap’, and ‘utilization gap’, which were discussed in existing information gap research. This implies that students from low-income families also have access problems related to physical access and are experiencing difficulties in accessing and utilizing digital devices and networks. Moreover, the gap in use and utilization of low-income students was identified as containing problems caused by the absence of a digital education environment, and as a way to resolve this, a digital education plan to strengthen attitudes toward digital technology and efficacy in using digital devices can be expected.

Published: January 2024

Objectives The purpose of this study is to examine the experiences of students participating in supporting their school meal service in and out of school, and to analyze the meaning of ‘student agency’ in the context of their experience.
Methods The six students of elementary, middle, and high schools and two college students (including graduates) in K province were selected as research participants for this case study. Six elementary, middle, and high school students participated in the activities for supporting school meal service, and took a part in the “Policy Meeting for Student Participation in School Meal Service” hosted by the K Office of Education, and two college stu-dents(graduates) published their episodes on their experience in their school meal service of their school days. The in-depth interviews were conducted for each group in July 2023, based on the semi-structured questionnaire provided to the participants.
Results The aspects of students' participation in school meal service were as follows: discussions and debates for decision-making on school meal service, events and campaigns for sustainable dietary habits, activities re-flecting students' opinions to change meal time, and implements of substantial nutrition·dietary education. In addition, as a result of analyzing the meaning of students' experience of participating in school meals from the perspective of ‘student agency’ practice, it was derived as follows: a liberal person who freely expresses and de-cides democratically, an active subject of solving school meal problems, a responsible person of individuals and communities, a representative of the public interest, and a messenger of solidarity and communication.
Conclusions According to the results of this study, it suggests that school meal service activities should be guar-anteed to students more practically at the levels of school, region and nation. Exploring new areas in which stu-dents can participate and providing a platform to guide students' participation, especially in and out of school, edu-cational subjects such as teachers, parents, and local communities should enhance their communication and co-operation for institutional complements.

Enhancing Indonesian customer complaint analysis: LDA topic modelling with BERT embeddings
Authors: Khadija Mutiara Auliya , Nurharjadmo Wahyu
Published: January 2024

Social media data can be mining for recommended systems to know the best trends or patterns. The customers have the freedom to ask questions about the product, tell their demands, and convey their complaints through social media. By mining social media data, companies can gain valuable insights into customer preferences, opinions, and sentiments. This information can be utilized to improve products and services, tailor marketing strategies, and enhance overall customer satisfaction. Topic modelling is a text mining technique that extracts the content from the raw and unlabelled data. Latent Dirichlet Allocation is popular for topic modelling research cause flexible and adaptive. But that method has issues with sparsity, performs poorly when documented in the short text and there is no correlation between topics that are actually important in text data. BERT is Bidirectional Encoder Representations from Transformer is designed to pre-train deep bidirectional representations from unlabelled text. The result of this research proves that Latent Dirichlet Allocation and BERT can be arranged on the topic of Indonesian customer complaints. BERT-Base Multilingual Cased and LDA have the highest coherence score. The combination of BERT-Base Multilingual Uncased and LDA has the highest silhouette score. BERT Multilingual are potential for improving the LDA method for Indonesian customer complaints topic modelling.
Law Enforcement Through Social Media Pressure
Authors: Abdul Azis
Published: January 2024

Problems related to efforts to apply the law from the past have seized the attention of the Indonesian people because they are considered a very important phenomenon because it has the potential to have significant implications for Indonesian law which is basically still widely misused by legal practitioners. If viewed from the perspective of legal policy formulation that is correlated with various legal institutions at various levels, the performance of the work shown is categorized as not yet ideal and has not been able to realize the actual target of implementing the law. This encourages people to often express their disappointment through social media. From information and dissemination of social media news, it often develops into public opinion which in the language of social media communication is often called “viral news” which sometimes leads to the encouragement of law enforcement to act no longer because of law enforcement efforts but has become the fulfillment of public satisfaction and tends to ignore legal norms. Social media has made people sometimes change their image in the hope of getting sympathy and favorable public opinion for them so that it often becomes hyperreality, not reality anymore. Hyperreality is a form and state where you cannot distinguish between reality and fantasy. Through this paper, the researcher tries to do mini research through the socio-legal method where through this method the author seeks to explore further and at the same time explore law enforcement by not only based on the study of legal norms or doctrines, but also trying to see the full context of norms and their application.
This study is solely aimed at providing an overview to the justice-seeking community that in the midst of uncertainty and rampant politicization of law enforcement, social media can be used as a force of coercion (pressure) as a means of law enforcement with justice.

ABSTRACT

 

Development engaged in the food sector is one of the country's needs in increasing production and meeting needs, especially food.  The Sustainable Food Yard Program (P2L) is one of the programs that is expected to be able to provide an increase in food production, especially for family consumption needs. The purpose of this study was to analyze the factors that influence the sustainability of the sustainable food garden program of women farmer groups in Lampung Province. The research method used is a quantitative method. The population in this study are members of the women's farmer group and stakeholders (stakeholders). Respondents studied amounted to 85 people. Data collection was carried out in June 2022. The data analysis method used was linear logistic regression analysis to determine the factors that influence program sustainability. The results showed that the level of sustainability of sustainable food gardens in Lampung Province was influenced by internal and external factors. Formal education, non-formal education, cosmopolitan level, number of family dependents, infrastructure, government support, market institutions and village nurseries and product marketing influence the level of sustainability of P2L in Lampung Province. Suggestions in this study are expected by certain parties, especially stakeholders and the government to be able to provide a forum and education for farmer women's groups in increasing knowledge and skills in managing and developing P2L programs.

The operation of high-pressure equipment requires special attention from the point of view of ensuring its safety. This problem is becoming increasingly relevant every year. According to various estimates, currently 60–80 % of high-pressure equipment at the industrial enterprises has already exhausted its standard service life. In this regard, there is a need to select and develop a promising method of operating production equipment that would consider the peculiarities of the state of modern domestic industry. The conducted analysis of the methods of operating high-pressure equipment showed that the strength criterion is used as the main criterion for assessing the technical condition of various devices and assemblies included in its composition. However, this approach contradicts the functional purpose of high-pressure equipment — its tightness. To increase the safety and tightness of such equipment when choosing a method of its operation, special schemes for sealing and monitoring of sealing units are proposed, allowing for conducting digitalization of their technical condition. Using this approach will allow to manage the process of ensuring the sealing of high-pressure equipment during its operation. Positive test results of the modernized sealing units in high-pressure equipment, subject to operating conditions, are a sufficient argument for its approval for use. The inclusion in the regulations on the system of maintenance and repair of enterprises operating hazardous production facilities, the requirements for ensuring the tightness of sealing units will allow: reduce the risk of depressurization of the sealing units; increase production profitability by reducing emissions; maintain the sustainability of the business using high pressure equipment. The feasibility of using this approach was repeatedly confirmed by the work of JSC IrkutskNIIkhimmash.

To analyze the functional characteristics of the «man — machine — environment» system and various factors influencing the occurrence of technogenic incidents at a open pit mining, a logical-stochastic model is developed. Within the framework of this model, it is proposed to consider both deterministic factors, such as working conditions or the state of equipment, and probabilistic (stochastic) factors, for example, random events or the human factor. The model allows for evaluating the probability of specific types of accidents or injuries based on these factors. The purpose of the work is to develop a logical-stochastic model of accident rate and injuries for the open pit mining system under consideration. The work implements an algorithm for a model of the stripping process for machine modeling of the process of the emergence of hazards and their development into the causal chain of a catastrophic accident and injury to personnel. The algorithm is based on the anthropogenic factors of a person psychophysiological properties and other factors determined by the reliability of the machine used by him, the comfort of the working environment and the level of organization of the technology of work being carried out. The model and the algorithm for occurrence of technogenic accidents at a open pit mining during the implementation of hazards in the system under consideration were developed. The algorithm is applicable to conduct a series of machine experiments and identify factors influencing the implementation of technogenic incidents. The combined model of the realization of hazard and the occurrence of a technogenic incident in the open pit mining system under consideration is presented, taking into account many fuzzy logic factors. The model improves modeling accuracy, uncertainty handling ability, and applicability to real-world problems, providing a flexible tool for analyzing complex phenomena when dealing with fuzzy information.
