Published: June 2023

There is a need to determine the relationship between the function of the
immune system and miRNA expression in pediatric celiac disease (pCD). We
aimed to describe the expression profiles of miRNAs in Turkish pCD patients
based on the clinical and pathological findings. This study was conducted on
33 pCD patients and 33 pediatric control subjects with normal biopsy
results. Four most common mutations (DQA1*05, DQB1*02, DQA1*03, DQB1*03:0.2)
on HLA gene in pCD were screened. Paraffin-embedded biopsy tissue samples
were used in miRNA isolations followed by cDNA synthesis. Expression of
miRNAs were evaluated in the groups with qRT-PCR array-method. Significant
underexpression of hsa-miR-194-5p gene was detected in pCD patients compared
to the control group. The hsa-miR-194-5p gene was significantly
underexpressed in anemic or short stature pCD patients compared to the
control. The genes of hsa-miR-29b-3p, hsa-miR-30e-5p, and hsa-miR-146a-5p
were significantly overexpressed in the patients with constipated celiac
patients. Significant overexpression of hsa-miR146a-5p gene was detected in
the Marsh2 and Marsh3a groups. The hsa-miR-29b-3p, hsa-miR-30e-5p,
hsa-let-7a-5p, hsa-miR-27a-3p, hsa-miR141-3p, hsa-miR143-3p, and
hsa-miR-146a-5p miRNA genes were significantly overexpressed in the Marsh3b
group. Also, the hsa-miR-194-5p and hsa-miR-26a-5p genes were significantly
underexpressed in the comparison of Marsh3c group to the control. These
results suggest that miRNA expressions are likely to play a role in the
pathogenesis of pCD. It is believed that the current results present
valuable inferences that may help understand the genetic boundaries on pCD,
which might be further supported by follow up studies on other miRNAs.

The aim of this study was determination of protein content and amino acid
composition in seeds of bread wheat, with particular focus of evaluation
essential amino acids (EAAs). For analysis used flour samples of grained
seed of 10 wheat variety, which selected in different breeding center (in
Novi Sad and Kragujevac, Serbia). Kjeldahl method was used for determination
of nitrogen (N) contents which value multiplied with coefficient 5.7 for
computing protein content (protein contents = 5.7 x % N contents). Amino
acids analyses of wheat samples were performed by ion exchange
chromatography, followed by the ninhydrin colour reaction and photometric
detection at 570 nm and 440 nm (for proline). The results showed that the
mean protein content for wheat varied from the lowest value 10.24% in
Ljubicevka to the highest 14.21% in Fortuna variety. The mean contents (g
100 g-l protein) of nonessential amino acids (NEAAs) were aspartic acid
5.42%, serine 4.23%, glutamic acid 18.51%, proline 12.18%, glycine 4.17%,
alanine 3.64%, tyrosine 2.52%, arginine 5.02%, while mean contents of
essential amino acids (EAAs) were threonine 2.86%, valine 4.52%, methionine
1.28%, isoleucine 3.87%, leucine 5.87%, phenylalanine 4.62%, histidine
2.46%, lysine 2.91%. The wheat variety contained relatively high
concentration of the most deficient EAAs. The variety Ljubicevka contained
relatively high concentration of the most deficient EAAs (threonine, valine,
leucine, lysine,). The highest value (29.31 g 100 g-l protein) of total
essential amino acids (TEAA), 59.79 g 100 g-l protein of total nonessential
amino acids (TNEAA) as well as the highest value (90.35 g 100 g-l protein)
of total amino acids (TAA). Obtained results provide variability of wheat
variety on the base of amino acid contents and indicate reliable variety for
selecting desirable parents in breeding program for improving nutrient
quality.

Published: June 2023

Cerebral Creatine Deficiency Syndromes (CCDS) are congenital metabolic
disorders in the creatine metabolism pathway. In this study, we evaluated
the clinical, phenotypic, radiological and genetic features of patients with
CCDS. We tried to identify early diagnosis clues in patients. Especially, we
reviewed the causes of delay in patients with late diagnosis. In line with
these findings, the diagnosis is confirmed by enzyme tests and next
generation sequencing based whole genome sequencing. In this study, 6
patients whose diagnosis was genetically confirmed were presented (5 GAMT
mutations (someone is complete homozygous deletion in GAMT gene), 1 SLC6A8
mutation). 5 of these patients were from the same family, and 4 patients
were patients with a late diagnosis. Two of the 4 patients who were
diagnosed late were moderate and two had severe phenotype. The neurological
findings consisted of patients with different clinical findings such as
speech disorder, cognitive retardation, autism and epilepsy. Patients
received appropriate treatment for the type of cerebral creatine deficiency.
While response to treatment was good in early diagnosed cases, a partial
clinical improvement was detected in cases diagnosed late. The patient, who
was started treatment before neurological symptoms appeared, was
neurodevelopmentally normal. It was observed that there was a strong
relationship between age at diagnosis and phenotype and prognosis. We
compared the clinical findings, phenotype and genotype characteristics of
patients with CCDS. We reviewed the causes of delay in patients with late
diagnosis. Thus, we wanted to raise awareness about early diagnosis and
treatment of CCDS, one of the rare metabolic diseases.

Published: June 2023

One of the arts in Surakarta culture is batik cloth. A batik is a form of heritage from the nation's ancestors whose manufacturing process must use specific tools and materials. Surakarta's typical batik has many patterns and motifs, such as Sawat, Satriomanah, and Semenrante. The pattern is a picture framework whose results will display the type of batik. A batik may resemble one type and another, so a classification technique is needed to determine the type of batik. This study aims to develop a classification method for batik cloth using the Naïve Bayes classification technique. The feature extraction used is the Gray Level Co-Occurrence Matrix (GLCM) to obtain texture values in each image. The stages in this research include pre-processing, feature extraction, classification, and testing. The training data in this study were 200 images for each Sawat, Satriomanah, and Sementrante class obtained from the data augmentation method by flipping, zooming, cropping, shifting, and changing the brightness of the images. The total sample data is 600 images. The amount of training data and data testing was divided three times (60% training and 40% testing), (70% training and 30% testing), and (80% training and 20% testing) for accuracy. In this study, the Naïve Bayes method using WEKA 3.8.6 tools obtained the best accuracy of 97.22% using a 70% percentage split compared to using 80% and 60% percentage splits with a result of 96.66%, this difference occurs due to differences in training data and test data. The results of this study indicate that the Naïve Bayes method can be used to classify batik cloth patterns based on texture feature extraction.

Authors: Angeli Aikaterini
Published: June 2023

In the age of migration, in order to remain competitive in the global marketplace, states are faced with the need to supplement their domestic labor resources with imported manpower. This whole exchange needs to be regulated accordingly regarding both admission and integration into a new country. Out of the advanced industrial states of the world, Japan is relatively new to the immigration game and its immigration policy is perceived as strict against importing labor from abroad. Recently, however, Japan has been showing promising signs of a shift towards a more open labor market for migrants through various reforms. This paper presents the evolution of the Japanese immigration policy, specifically regarding migrant workers, since it first acquired its status as an “Immigration State”, while it also addresses the public opinion surrounding the matter, which does not seem welcoming of the new additions in the Japanese society.

According to the obtained results, established that implementation of the complex reduces the consumption of irrigation water by 2.2–30.7% and electricity consumption by 12.9–38.2%. The rate of specific costs decreases from 1.6 to 1.32–1.47, and the coefficient of environmental reliability increases by 5.6–16.7%. At the same time, the profitability index increases from 1.07 to 1.75–2.57, and the discounted payback period decreases from 18 to 8–5 years.
Role of reservoirs of urban heat island effect mitigation in human settlements: moderate climate zone
Authors: Sierka Edyta , Pierzchała Łukasz
Published: June 2023

This paper presents the problem of the increasing negative impact of urban heat islands (UHI) on urban residents based on land surface temperature (LST). It is assumed that water bodies in the agglomeration remain cooler than the air and surrounding urban areas. The study aimed to determine the impact of water bodies and surrounding areas covered by trees on the temperature of an urban area and to minimise the impact of UHI on the life quality of people in the temperate climate zone at day temperatures 25°C (W day) and 29°C (H day). In the adopted research methodology, 167 reservoirs, larger than 1 ha, located within 300 m of urban areas, were analysed. Satellite thermal imagery, spatial land use data (Corine Land Cover), and local land characteristics were used. The average temperature of the reservoirs was appropriately at 4.69°C on W day and 1.9°C for H day lower than in residential areas. The average temperature of areas at a distance of 30 m from the reservoirs was 2.69°C higher onWand 0.32°C higher on H than the water of the reservoirs. The area covered by trees was 0.52°C lower on W day and 0.39°C lower on H day than the residential areas located at a distance of 300 m from the reservoir. On terrestrial areas, the lowest temperature was observed in the area covered by trees within 0–30 m from reservoirs both on warm and hot days. Based on the results of this study, UHI mitigation solutions can be suggested.
Numerical Analysis of the Diversity of Keyboard Instrument Playing Fingerings
Authors: Wang Huaijin
Published: June 2023

Fingering is the foundation of keyboard instrument performance and an important part of keyboard music, but few people pay attention to its development. The evolution from the early variety of playing fingerings to the thumb-centered five-fingerings is even less mentioned. At present, steganographic analysis mainly focuses on the diversity and high dimensionality of features. Faced with the emerging new steganography, it is difficult for a single feature to cover and express the influence of steganography process on the multi-dimensional distribution of images. Therefore, it is necessary to combine various features through certain methods to analyze the changes of image properties before and after steganography embedding in a larger range and more types. The experimental results show that the experimental comparison diagram of Comb-RichModel based on diversity features and other steganographic analysis algorithms can be seen by replacing filtering and adding SPAM features. Compared with numerical analysis, the detection accuracy of the Comb-RichModel with diversified features has been improved to some extent, and its detection performance has improved stably from low embedding rate to high embedding rate. It is proved that the numerical analysis can effectively analyze the diversity characteristics of keyboard instrument playing fingerings.

Then the AHP method is used to study the weight of each evaluation index. The review found that the online education of ideological and political courses in universities is generally “strong” under the current situation. Based on this, this paper comprehensively evaluates college students’ ideological and political work. Educational institutions can then develop targeted improvement plans on a quantitative basis. The results of this paper lay a foundation for the implementation of precision teaching.

Authors: Tian Ben , Xie Zhaogang
Published: June 2023

This paper studies the coupling of the five links of ADDIE and the five essential elements of the ideological and political classroom teaching model. Secondly, based on the ADDIE model, the curriculum system of “analysis - design - development - implementation - evaluation” of ideological and political courses is established. It is found that the five modules of ADDIE are closely related to the five core elements. Each link of ideological and political revolution is divided into several specific sub-units. Analyzing the ADDIE model of “ideological and political” curriculum reform can effectively mobilize students’ enthusiasm. This paper has specific reference value to the teaching practice of ideological and political courses in colleges and universities. The conclusion of this paper has a particular reference value for preparing and exploring curriculum thinking in universities.
Marginal Scale State Analysis of Cloud Computing Economy Based on a Class of First Order Differential Equations
Authors: Li Jianwei
Published: June 2023

This paper studies the internal effects of cloud technology on the economic development of our country based on a primary differential equation. As the main production factor, cloud technology has expanded enterprises’ economic growth. The first is to separate cloud computing from physical production as an emerging mode. In the framework of “innovation destruction,” the end biochemical technology in the cloud is introduced into the product function, and the mass cascade model of the first-order differential equation is established. It can be seen from the theoretical deduction that cloud computing plays a vital role in improving the “multiplier effect” of product quality and leading to the “transformation of research and development mode.” Secondly, the way and mechanism of cloud computing to promote technology development and economic development are studied, and numerical simulation is carried out. The results show that “convergence costs” between cloud computing and other manufacturing factors cause “R&D shifts.” This harms the short-term economic output of enterprises.

Authors: Zhu Sanmei
Published: June 2023

In order to solve the problem of electric Internet of Things intelligent terminal equipment construction, in this essay, aiming at the research of electric Internet of Things networking scheme, an electric Internet of Things intelligent terminal equipment system with edge computing technology is designed. Through MATLAB2017 simulation of electric intelligent terminal equipment effect diagram, the test hardware environment uses Intel(R) Core(TM) i7-3770 CPU@3.40 GHz type processor, and data memory is 160 GB, The server operating system is WindowsServer2017. The results show that the success rate of edge computing in cloud data networking is not superior to the other two methods. The success rate of networking is 40%~50%, but the success rate of networking data is significantly higher than that of optical fiber communication and terminal access networking. The success rate of edge computing networking can reach 70%, while the success rate of terminal access networking is about 55%. Fiber optic communications can only reach 45%. Compared with the other two methods, edge computing is more stable and has a higher success rate. This system has short communication delay and large communication pulse width, which can not only solve the problem of long delay time in traditional networking mode, but also use fewer communication lines and save power resources.

A three-year rotation of cotton (Gossypium hirsutum) cultivars either resistant (R) or susceptible (S) to Rotylenchulus reniformis and fallow (F) was examined for effect on cotton yield and nematode density. In year 1, 2, and 3, the resistant cultivar (DP 2143NR B3XF) yielded 78, 77, and 113% higher than the susceptible cultivar (DP 2044 B3XF). Fallow in year 1 followed by S in year 2 (F1S2) improved yield in year 2 by 24% compared with S1S2, but not as much as R1S2 (41% yield increase over S1S2). One year of fallow followed by R (F1R2) had lower yield in year 2 (11% reduction) than R1R2. The highest yield after three years of these rotations occurred with R1R2R3, followed by R1S2R3 (17% less yield) and F1F2S3 (35% less yield). Rotylenchulus reniformis density in soil averaged 57, 65, and 70% lower (year 1, 2, 3, respectively) in R1R2R3 compared with S1S2S3. In years 1 and 2, LOG10 transformed nematode density (LREN) was lower in F1, and F1F2, than for all other combinations. In year 3, the lowest LREN were associated with R1R2R3, F1S2F3, and F1F2S3. The highest LREN were associated with F1R2S3, F1S2S3, S1S2S3, R1R2S3, and R1S2S3. The combination of higher yield and lower nematode density will be a strong incentive for producers to use the R. reniformis resistant cultivars continuously.
Modelling of the Monolithic Stiffener Forming Process from a Paek Thermoplastic Composite Matrix Using Pam-Form Software
Authors: Polański Witold
Published: June 2023

The growing use of thermoplastic composites in aviation, automotive, sports and medical industries is forcing the development of processing technology. Due to the properties of thermoplastic composite materials, their shaping is subject to many restrictions. For this reason, it is not always possible to obtain components with complex geometry and adequate quality. By using numerical analysis and experience in the production of parts using hot pressing technology, we are able to predict the course of the process and the behaviour of the material during formation. The article describes how to build a model for numerical analysis of the process of thermoforming monolithic inspection door stiffening for an ILX-34 aircraft using a Toray Cetex® TC1225 carbon composite material with a thermoplastic polyaryletherketone (PAEK) matrix. Pam-Form v2019.0 software version V1.9.N was used for modelling. The results of the analysis were compared with those of the part produced by the Institute of Aviation, Łukasiewicz Research Network.
Exploring Indonesian EFL teacher-student interactions in online learning

Published: June 2023

The use of online platforms has been shown to help students engage in learning writing. The student’s engagement in revising their writing draft can be seen from the interactions between the teacher and the students or among the students. This study aims to determine teacher-student interactions in a writing class conducted synchronously and asynchronously via Google Classroom, Google Meet, and WhatsApp. The data were derived from the teacher’s and students’ discussions posted in written and oral modes in the applications. A qualitative approach in designing and gathering the data was used in this study. The findings show that the interactions between the teacher and the students raised the students’ understanding of the teacher’s instruction so that the students were engaged in writing their drafts and revising them properly. The patterns of the teacher’s interactions can be categorised into giving feedback (39%) followed respectively by prescribing the editor role (17.7%), promoting individual contributions (13.3%), promoting joint construction of meaning and form (11%), thanking and praising (10%), guiding through the writing steps (5.7%) and stimulating students (3.3%). Students’ responses toward the teacher’s patterns of interaction depend on the teacher’s talk. There is no initiative from the students to start the discussion. The student’s background as freshmen can cause this; the first-year students may not be brave enough to start the discussion. This suggests that exploring the interactions between the teacher and students of different backgrounds is necessary.

This study aims to investigate undergraduates’ perspectives toward personality traits, presentation skills, and audience factors based on their experiences in online oral presentations as assessment tasks during English language classes. It also examines the factors affecting online oral presentations and suggestions to overcome them. To achieve this purpose, an online questionnaire with 5 sections and 28 items was distributed to 90 university undergraduate students. The data were analyzed descriptively using SPSS (version 26).  The results revealed that the undergraduates’ perceptions of online oral presentations depended on three essential factors. Personality traits included fears of failure in the oral presentation assessment resulting in students’ anxiety even when they were well prepared. Oral presentation skills included their concerns on grammar, vocabulary, pronunciation, and reading from notes during the oral presentation. The audience included feeling frightened to present in front of an audience and worried if their peers were better than them. To conclude, the important factors that students realized were the audience, personality traits, and presentation skills. Hence, suggestions that students had provided included having enough preparation and practice as well as receiving good support from lecturers. This study highlights the vital role of lecturers in preparing learners for online oral presentations and underscores the need for guiding effective preparation strategies such as practice sessions.
The language contact phenomenon in Thailand: English borrowing, comprehension, and public attitudes
Authors: Whanchit Wararat , Sukkaew Nootchanat
Published: June 2023

As the English lexicon has become more frequently borrowed and used in Thai mass media and social media, Thais are quickly adapting to such foreignness and are open to language contact-induced change. The current study explores the extent of the public’s familiarity with borrowed words in contemporary Thai public media and attitudes toward language borrowing. The study participants comprised 120 Thais who voluntarily completed a questionnaire. They were from different age groups and were relatively highly educated. The instrument for the data collection was an online three-part questionnaire probing demographic information, an individual’s comprehension of the borrowed lexicon as tested via 15 questions of lexical borrowing in context, and personal views probed in the questionnaire questions about English lexical borrowing. Follow-up interviews with six selected respondents according to age groups verified and elicited attitudes toward lexical borrowing. The findings revealed that high exposure to English resulted in a high level of comprehension, especially when words were transcribed in the Thai script with tone markers. If the borrowing was in Romanized script, it was less likely to be understood. The majority of the respondents recognized the need for English language borrowing in Thai communication, especially for terminology. They also expressed positive views toward the adoption of the practice. English was perceived as necessary for effective Thai communication, particularly among acquaintances and professionals. The ubiquity of English in Thai society today has led to general adaptability and acceptance of borrowing as part of language evolution; such practices are no longer a sign of prestige. The study suggests that language classrooms should consider using borrowed English lexicons to assist Thai EFL learners in developing English proficiency.
