Published: January 2024

Background. Feeding difficulties continue to be a serious problem in newborns with hypoxic-ischemic encephalopathy (HIE) undergoing therapeutic hypothermia (TH). The aim of this study was to investigate the efficacy of oral motor interventions (OMI) on feeding outcomes in neonates with HIE/TH.
Methods. This was a prospective randomised control study conducted between January 2022 and September 2022. Premature Infant Oral Motor Intervention (PIOMI) was used as OMI. Newborns with HIE/TH, who underwent PIOMI, constituted the study group, and newborns, who did not receive any feeding exercise, constituted the control group. Transition time to full oral feeding (FOF) was determined as the time between initiation of tube feeding and full oral breastfeeding or bottle feeding. The day per oral (PO) feeding was started was specified as PO first, the day the infants could take half of the volume of the feedings by mouth was PO half, and the day the infants could take all the feedings by mouth was PO full.
Results. There were 50 neonates in each group. Time to FOF was significantly shorter in the study group than in the control group in all stages of HIE/TH (P= 0.008 for stage 1, and < 0.001 for stage 2 and 3 HIE). However, times to PO first, PO half, PO full and discharge were shorter in the study group than in the control group only in the neonates with stage 3 HIE (P= 0.003, 0.014, 0.013, 0.042, respectively).
Conclusions. The PIOMI, which could be named as `HIE-OMI` in our study, is an effective intervention in shortening the transition time to FOF in neonates with all stages of HIE undergoing TH. In addition, `HIEOMI` shortens the length of hospital stay, and improves feeding outcomes in neonates with severe HIE/TH.

Published: January 2024

The main purpose of this journal is to describe the cultural change in the practice of Pikukuh Karuhun (The Law of Baduy people that governs their relation with nature). While most of the people of Inner Baduy (locally known as Baduy Dalam) in Cibeo still strongly clings into these ancient laws, the youths of said village have started to use technologies in their daily lives, most often to communicate with guests who planned to visit their village. The researchers of this journal tried to study this change that occurs in Cibeo’s youths, specifically about their stance on Pikukuh Karuhun as a local culture that functions to philosophically guide Baduy people on their daily lives. This study was done with ethnomethodology method which is a part qualitative method and constructive paradigm. The results of this research describe the inconsistencies in the practice of Pikukuh Karuhun by Cibeo’s youths that mostly works as local guides and porters in weekends and holidays. They use social media like WhatsApp to communicate with would-be guests before and after their arrival. Their aptitude in using such apps come from their interaction with outlanders that come to visit Cibeo. In-between their interaction with outside visitors, they autodidactly learn to operate phones and social medias as much as they could. Interestingly, researchers found that while they use technology in the form of mobile phones (something that is forbidden by their ancient laws), they only do so outside their village. They never bring their phones into the village but instead they leave it at the hand of their relatives and friends outside Cibeo.

The People's Legislative Council of the Republic of Indonesia (DPR RI), like parliaments in other countries, is developing its institutional governance towards a modern parliament. The idea of a modern parliament is a strategy to increase public trust in the DPR RI. This study aims to generate public views about the image of a modern parliament as the embodiment of good government governance. Using the case study method to find the actual image representation. Conducting interviews with various sources of information both internal and external stakeholders and also reviewing documents for the validity of the data. The study found that the achievement of modern parliamentary indicators, namely transparency, technology, and representation, was still experiencing obstacles in the form of not fulfilling these three indicators. Of the three, only technology indicators have shown their best achievements in the form of easy public access to official information on the parliament website. Transparency and representation have not been fully open and in accordance with public expectations. Seen by the large number of public participation in the form of criticism, suggestions, proposals that oversee the performance of the parliament. This study concludes that the modern parliament as an embodiment of good governance in the Indonesian Parliament is carried out through strengthening the aspects of transparency, technology and representation. Efforts towards a modern parliament in realizing good governance still need time and follow the dynamics of society and the changing times.

Published: January 2024

A prototype design of an automated system for urine bag emptying using an Internet of Things (IoT) based ultrasonic sensor has been developed. The system comprises an HC-SR04 Ultrasonic Sensor, an SG90 Micro Servo Motor, NodeMCU ESP8266, a Liquid Crystal Display (LCD), and Blynk integration. The servo motor is employed to open the valve for urine discharge and close it once the process is completed. The servo motor's movement is determined by the urine's detected height using the ultrasonic sensor, and it can be controlled through the Blynk platform. The reference heights for urine management are set at half the urine bag's capacity or 8 cm, triggering a 180Âº rotation of the servo motor, and at 0 cm, causing the servo motor to move to 0Âº. The measured urine height is displayed on the LCD and the Blynk IoT interface. The ultrasonic sensor's characterization results reveal an error percentage of 0.02%, a sensitivity value of 58.203 Âµs/cm, an offset value of 0.0123, and a coefficient of determination R2 of 0.9999. Based on the conducted measurements, analysis, and testing, it can be concluded that the system functions effectively.

Suggested Scenarios of Initial Filling for the Badush Reservoir, Iraq
Authors: Badawy Maha Shahir , Saleh Sabbar Abdullah , Abbood Mohammed Rashid
Published: January 2024

This study developed hypotheses based on the geometric analysis of the Badush Dam reservoir to simulate the initial filling and operation of the dam reservoir. A mathematical equation was developed to estimate the daily demand for water behind the dam, and then build an EXCEL program for calculating the input demand, output discharges, and the storage difference for the dam reservoir. Conditions and parameters for continuous/rapid filling and others for gradual filling of the reservoir were arranged in the program. The daily input discharges records, demand, and output discharges produced for the two wet and dry years selected from the records released from Mosul dam to implement the scenarios of rapid and gradual filling of Badush reservoir. The results showed that the reservoir could be filled within 20 or 130 days, according to the continuous (rapid) filling program in the wet or dry years, respectively, and the possibility of filling the reservoir within 133 or 258 days, according to the gradual filling program in the same two wet or dry years, respectively. The operation was more flexible in the dry year than the wet because the wet years may have high daily discharge releases from Mosul Dam, which requires careful monitoring of the Badush reservoir levels. After all, it may rise in a critical period and needs quick intervention by the operator. In rapid filling, it was noted that the daily increase during the days of storage in a wet year was about 1-2 m/day while no more than 1 m/day for the dry year. Regarding the gradual filling, the daily increase during the days of storage in the wet year varied between 1-3 m/day on some days that do not coincide with the peak flood wave. In the second stage, which lasted only two days, the level rose between 3-4 m/day. The third stage, which lasted only one day and coincided with the peak flood, was accompanied by a sharper increase in the level, reaching 7 m/day. The daily level increased from a few centimeters to 2 m/day through the gradual filling in the dry year.
The City of the Future in the novels by V.F. Odoevsky "Russian Nights" and "The 4338th year
Authors: zhao Yao
Published: January 2024

The article offers a comparative consideration of two social models in the fiction of V.F. Odoevsky. The researcher focuses on the unfinished novel "4338" and the insert novella "The City without a Name" from the novel "Russian Nights" by Odoevsky. When comparing both texts, the article points to the indissoluble semantic unity of the author's cultural and social views on the proper (ideal) future society.  If "Russian Nights" is entirely turned to the present, so that the dystopian paintings in the short stories "The City without a Name" and "The Last Suicide" are needed only to properly look at the modernity of the 1840s and the consequences of mistakes that can be made in the present, then "4338" really aspires and into the future and projects a new scientific and social world. "4338th year" can only be considered a utopia in part. In the light of satirical criticism in the novel "Russian Nights" and other works by Odoevsky, "The 4338th year" turns out to be not so unambiguous a text as was commonly believed in literary studies of the early twentieth century.

Multisensor Integrated Autonomous Navigation Based on Intelligent Information Fusion
Authors: Yuan Ying , Yu Feng , Zong Hua
Published: January 2024

A major inadequacy of the Kalman filter is the necessity of accurate measurement models, which may not be possible in the case of complicated disturbances. A new solution to multisensor integrated autonomous navigation based on intelligent information fusion technology for launch vehicles is proposed in this paper, which can improve navigation performance based on the existing measurement models. Artificial neural networks (ANNs) are designed to discover the hidden relationship between the available data and trajectory parameters. The tracking, telemetry, and control system can provide centimeter-level accuracy of the launch vehicle after every flight. While postprocessing data is irrelevant to real-time navigation using traditional methods, it is crucial for ANNs to learn the rules of information fusion and identify the inaccuracy of the input variables. In this way, artificial-intelligence-modified trajectory parameters are expected to be closer to the truth value. The experimental results indicate that the proposed method can significantly improve navigation performance compared with the unscented Kalman filter, and ANNs can achieve good performance in various situations.
Performance Evaluation of Damaged Blades Using Numerical Simulation and Machine Learning
Authors: He Qingfu , Liu Yafei , Chi Zhongran , Zang Shusheng
Published: January 2024

The formulation of maintenance strategies for gas turbines requires an accurate and rapid assessment of damaged blade performance. Variety and uncertainty in the three-dimensional geometric deformation of gas turbine vanes and blades increase the difficulty of degradation analysis. In this paper, the effects on the aerodynamic performance of partial damage to turbine nozzle guide vanes are investigated experimentally and numerically. A methodology for constructing a deformation–degradation model for high-pressure gas turbine vanes/blades is proposed based on machine learning. A database consisting of 670 numerical simulation results with various deformation patterns is constructed for the vane cascade. A mapping is constructed between the matrices defining geometric deformations and the total pressure loss coefficient of the cascades based on a convolutional neural network model. The accuracy of this deformation–degradation model is verified against experimental results. We find that deformation on the suction side of the blade has the most significant influence on aerodynamic performance. The deformation–degradation model constructed for a specific cascade provides a rapid evaluation of aerodynamic performance based on rough geometrical measurements without additional experiments or numerical simulations, providing a potential tool in the precise repair of gas turbines.
High-Order Guidance for Time-Optimal Low-Thrust Trajectories with Accuracy Control
Authors: Evans Adam , Armellin Roberto , Pirovano Laura , Baresi Nicola
Published: January 2024

This paper develops a high-order guidance scheme based on the expansion of the solution to a time-optimal low-thrust optimal control problem by using differential algebraic techniques. The result allows new optimal trajectories to be autonomously computed from the simple evaluation of polynomials, including updated times of flight. Furthermore, a differential algebraic technique known as automatic domain splitting is implemented to improve the guidance scheme by adaptively and automatically splitting the uncertainty domain into smaller subdomains, in which new guidance polynomials are then generated which are better equipped to handle deviations in their respective subdomains. The result is not only a more effective handling of deviations in the trajectory compared to previous algorithms which use just a single set of polynomials but one that can provide the control and time-of-flight updates to a desired accuracy across the entire domain. Combined with its high-order nature, the guidance scheme is capable of dealing with nonlinearity and large deviations with respect to the reference trajectory, thus being robust to mismodeling and unplanned events. The guidance scheme is evaluated in three scenarios: simplified rendezvous using Clohessy–Wiltshire equations to demonstrate automatic domain splitting in the guidance problem, an Earth–Mars transfer, and an asteroid landing trajectory. The results show the ability of the differential algebraic-based guidance to provide optimal control and time-of-flight updates and improvements of several orders of magnitude over previous differential algebraic-based schemes in handling large uncertainty experienced in spaceflight by leveraging automatic domain splitting.
AFJPDA: A Multiclass Multi-Object Tracking with Appearance Feature-Aided Joint Probabilistic Data Association
Authors: Kim Sukkeun , Petrunin Ivan , Shin Hyo-Sang
Published: January 2024

This study addresses a multiclass multi-object tracking problem in consideration of clutters in the environment. To alleviate issues with clutters, we propose the appearance feature-aided joint probabilistic data association filter. We also implemented simple adaptive gating logic for the computational efficiency and track maintenance logic, which can save the lost track for re-association after occlusion or missed detection. The performance of the proposed algorithm was evaluated against a state-of-the-art multi-object tracking algorithm using both multiclass multi-object simulation and real-world aerial images. The evaluation results indicate significant performance improvement of the proposed method against the benchmark state-of-the-art algorithm, especially in terms of reduction in identity switches and fragmentation.
High-Temperature Nonequilibrium Air Chemistry from First Principles
Authors: Torres Erik , Geistfeld Eric C. , Schwartzentruber Thomas E.
Published: January 2024

We present first-principles calculations for chemically reacting five-species air ([Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text]) over a range of gas temperatures ([Formula: see text]), relying exclusively on ab initio potential energy surfaces (PESs) from the University of Minnesota Computational Chemistry group to describe the forces between atoms. We use these PESs within direct molecular simulations (DMSs) and quasi-classical trajectory (QCT) calculations to determine the coupling of internal energy relaxation to chemical reactions. From DMS we extract the internal energy populations of diatomic species during the quasi-steady-state (QSS) dissociation phase and, for all diatomic species, observe depleted high-energy tails relative to corresponding Boltzmann distributions. A comparison of thermochemical equilibrium rate coefficients (from QCT) with those during QSS (from DMS) helps quantify the macroscopic effects of vibrationally depleted distributions on dissociation. In contrast, Zeldovich exchange reactions are almost unaffected by these vibrationally depleted distributions. Unlike dissociation, they do not exhibit significant vibrational bias and take place at near-thermal rates at all temperatures studied. Furthermore, we quantify the amount of vibrational and rotational energy removed and/or gained in exchange and dissociation reactions. Such macroscopic quantities are of interest for enhancing the fidelity of multitemperature nonequilibrium chemistry models used in computational fluid dynamics codes.

Published: January 2024

This research stems from the broad use of AI based on Large Language Models (LLMs), which many academics find relevant and effective in higher education Arabic language learning. The goal is to confirm these views.This research is a mixed reseach that employs a both of qualitative and quantitative methodologies. The qualitative segment involves observations and literature reviews. Observations involved reviewing how participants used chatbots and carefully checking the accuracy and consistency of platform responses. The quantitative facet utilizes a paired experimental design, encompassing both classical and Bayesian Paired Sample t-Tests analysis. The research encompasses 45 individuals with a proficient understanding of Modern Standard Arabic and no hindrances in comprehending the material. These individuals are enrolled as students at Islamic College (STAI) Al-Anwar Rembang, Indonesia. The results show increased motivation and ease of use with the chatbot in Arabic language learning. However, concerns about the consistency of chatbot content have arisen, affecting participants' confidence in response accuracy of AI. This prompts an evaluation of effectiveness through classical and Bayesian tests, which fail to demonstrate statistically significant variances, even in the adaptive Bayesian probability analysis. These outcomes deviate from previous research on relevance and effectiveness and corroborate preceding studies on academic apprehensions and accuracy enhancements. The researchers advocate for further investigations, especially concerning the accuracy analysis of AI chatbots in Arabic pedagogical contexts.

Published: January 2024

This study examined the reflections of four Korean pre-service elementary teachers regarding their three-week overseas teaching practicum in the United States and how the overseas teaching practicum contributed to the development of their English teacher agency. The study was conducted as a case study, and the participants’ interview transcripts and final reports were collected as data for analysis. The collected data were explored using thematic analysis. Two major themes were found in this study. First, the pre-service teachers developed confident English teacher agency. Second, the pre-service teachers developed their teacher agency under full awareness of the different school cultures focusing on teacher assistance system and classroom environment management. This study highlights the teachers’ own decision to free themselves of the burden of the Teaching English in English (TEE) policy and the conservative Korean school culture. The study concludes with important implications and suggestions for future research on the pre-service elementary teachers’ overseas teaching practicum and the development of their English teacher agency.

Authors:   The Korea Association Of Primary English Education, Son Yoojeong , Youn Soo Jung
Published: January 2024

The purpose of this study is to investigate a task-based language teaching (TBLT) approach to teaching pragmatic competence for EFL elementary English learners focusing on requests. A series of 15 task-based lessons was developed to teach requests to 6th-grade English learners for eight weeks. In terms of choosing target request expressions, various request expressions were initially extracted from the English curriculum and textbooks and additional request strategies were added. Three target tasks that require request expressions were designed, incorporating pragmatic social variables such as power, distance, and imposition. Each task differed in terms of difficulty and complexity. Students’ pragmalinguistic competence and sociopragmatic competence were evaluated using a discourse completion test (DCT) as pre- and post-tests. Rating criteria, assessing pragmalinguistic and sociopragmatic competence, were also developed and two raters evaluated the learners’ pragmatic production on DCT items to ensure inter-rater reliability. The findings revealed that the TBLT approach was effective in teaching EFL elementary school students’ request competence in terms of both pragmalinguistic and sociopragmatic components. We discuss potential challenges and directions in teaching pragmatic competence for elementary school students in Korea.
Exploring the potential of utilizing ChatGPT in elementary English lesson planning and English language teaching
Authors:   The Korea Association Of Primary English Education, Kim Eunsong , Ahn Kyungja
Published: January 2024

This study aims to verify the validity of elementary English lesson plans generated by ChatGPT and investigate teachers’ perceptions of the educational utilization of ChatGPT. Fifty elementary teachers participated in the research, and among them, three participants were selected for in-depth interviews. The findings from the collected data, analyzed quantitatively and qualitatively, are as follows: (1) The validity of the ChatGPT-generated lesson plan was high, particularly receiving higher scores in the areas of lesson goals and assessment. (2) Regarding the validity of lesson plans based on teachers’ demographic variables, significant differences were only observed concerning teachers’ final degree and completion program, with no differences found among their gender, teaching and ELT experiences, and experience with using ChatGPT. (3) Regarding teachers’ perceptions of the educational utilization of ChatGPT, generating and translating teaching materials were found to be beneficial to teachers, while writing assistance and feedback provision were considered useful for learners. Conversely, concerns were highest for inaccurate or false information provision, followed by difficulties in plagiarism detection. These results suggest that ChatGPT can be effective in generating elementary English lesson plans, but critical reviews by teachers are essential. Furthermore, enhancing teacher competence through teacher education is crucial for the successful integration of technology into teaching.

Published: January 2024

Spin coating is a wide-spread, quick, and inexpensive method to create nanometer-thick thin films of various polymers, such as polystyrene, on top of solid substrates. Since the film thickness determines the mechanical, optical, and degradation properties of the coated film, it is essential to develop a simple method to predict thickness based on other manipulatable factors. In this study, a three-dimensional manifold relating initial solution concentration, thin film coverage thickness, and monodisperse bulk molecular weight is developed utilizing curve-fit machine learning. The model is able to receive polystyrene bulk molecular weight and desired thin film thickness as input and output an accurate prediction of initial solution concentration required to generate a coating of a desired thickness.

Fibroblast Growth Factor Receptor 4 (FGFR4) is thought to be a driver in several cancer types, most notably in hepatocellular carcinoma. One way to achieve high potency and isoform-selectivity for FGFR4 is to covalently target a rare cysteine (C552) in the hinge region of its kinase domain that is not present in other FGFR family members (FGFR1-3). Typically, this cysteine is addressed via classical acrylamide electrophiles. Here, we demonstrate that non-canonical covalent “warheads” based on nucleophilic aromatic substitution (SNAr) chemistry can be employed in a rational manner to generate highly potent and (isoform )selective FGFR4 inhibitors with a low intrinsic reactivity. Our key compounds showed low- to subnanomolar potency, efficient covalent inactivation, and excellent selectivity over other FGFRs as well as kinases with an equivalent cysteine and a representative subset of the kinome. Moreover, these compounds achieved low nanomolar potencies in cellular assays and demonstrated good microsomal stability highlighting the potential of SNAr-based approaches in covalent inhibitor design.
