Learning media can serve to improve 5 aspects of child development, one of which is language, namely speaking. One of the media is learning video. Linguistics stage IV (pre-language) is the stage where the ability of children aged 5-6 years can be said to be able to speak with a good sentence structure, have a lot of vocabulary, and dare to speak in public. But in reality, some children have not developed properly. This study aims to determine the effect of the use of learning videos on the speaking ability of children aged 5-6 years. The research was conducted using a quantitative approach with a quasi-experimental research model which was divided into 2 groups, namely control and experiment. The group that was given treatment with learning videos was only the experimental group. The results show that the control and experimental groups have differences. This was proven when the T test was analyzed with the aim of knowing the differences between the two groups. These results are further strengthened by testing the hypothesis. And the results are similar, there are significant differences and influences from the two groups. The use of learning videos can have a positive and significant effect on the speaking ability of children aged 5-6 years who are in the linguistic stage IV (pre-language). Media pembelajaran bisa berfungsi untuk meningkatkan 5 aspek perkembangan anak, salah satu aspeknya adalah bahasa yaitu berbicara. Media tersebut salah satunya adalah video pembelajaran. Tahap linguistik IV (prabahasa) merupakan tahap dimana kemampuan anak usia 5-6 tahun telah dapat dikatakan mampu untuk berbicara dengan struktur kalimat yang baik, memiliki banyak kosa kata, dan berani untuk berbicara di depan umum. Tapi kenyataannya, beberapa anak belum berkembang dengan sesuai. Penelitian ini bertujuan untuk mengetahui pengaruh dari penggunaan video pembelajaran terhadap kemampuan berbicara anak usia 5-6 tahun. Penelitian dilakukan dengan menggunakan pendekatan kuantitatif dengan model penelitian kuasi eksperimen yang terbagi dalam 2 kelompok yaitu kontrol dan eksperimen.

In this study, the development of a solar-powered autonomous vehicle prototype with an object detection and avoidance system was implemented and achieved using Raspberry Pi. The advancements in science and technology research have given rise to the robust adoption of smart means of transportation, from steam engines to energyefficient means such as solar, electric, and hybrid-powered vehicles to ease transportation of people, goods, and services with increased human comfortability. Autonomous vehicles (AVs)offer a degree of self-control in driving in which a normal car requires a driver to execute such tasks e.g., braking, acceleration, and steering. An autonomous vehicle, requires sensors, controllers, algorithms, actuators, computers, and advanced software embedded in various locations on the vehicle to perform effectively. The study attempted to proffer solutions to the menace of human errors in decision-making while driving through the use of advances in scientific technology that have given rise to modern approaches to problem-solving. In Nigeria, almost 50% of road accidents were a result of poor decisions leading to the loss of lives and properties. The vehicle uses ultrasonic sensors and a USB webcam to detect and avoid obstacles on its path with the aid of a Raspberry Pie program that effectively executes decision-making changes to manoeuvre the vehicle away from objects on a free path. The study observed that as motor frequency is increased the speed of the AV increases and thus covers distances faster as compared to when the frequency is reduced. However, the increase in frequency also consumes energy faster. Charging rates were compared between the grid and solar photovoltaic, the grid system recorded faster charging rates when the vehicle was stationary while the solar photovoltaic charged the vehicle at stationary and in motion.

Nowadays, the construction sector is developing rapidly, and there is an increase in demand for innovative concrete technology. This is because concrete has many advantages over other building materials. Improving the quality of concrete can be done by providing replacement materials or adding several replacement materials, and one of the alternative materials that can be used is styrofoam. The purpose of this research is to evaluate the effect of styrofoam as high-quality concrete and compare the compressive strength between control concrete by using 1%, 2%, and 3% ratios of styrofoam. The experimental method is applied in this research, experiment was conducted and tested in accordance with SNI 03-6468-2000. The results of the study show that the compressive strength of styrofoam mixed concrete using ratios of 1%, 2%, and 3% obtained 23,30 MPa, 17,34 MPa, and 11,64 MPa. The results showed that Styrofoam replacement was used for K.350 high-strength concrete. It is not recommended for building or bridge construction because the compressive strength test results produced are meagre compared to standard concrete without a mixture of styrofoam. After all, the mass of concrete mixed with styrofoam is lighter than normal concrete so that it can be used for construction with low loads.

Personalised e-learning aims at providing a personalisation effect based on the learner’s characteristics such as knowledge level, preferences, and learning style. The support derived from using social collaboration tools like social media reflects the discovery of these characteristics from content generated during collaboration. The collaboration process is guided using different annotations equipped with the collaboration tool. This type of system needs to be evaluated in terms of usability factors including usefulness, ease of use, and System Usability Scale (SUS). These evaluation factors reflect the objectives of the system based on the different functionalities provided. Thus, the correlation between these factors and how they are related to the system objectives is needed to be validated. This validation is performed using Principal Component Analysis (PCA) utilising PerLCol framework as discussed in this paper. PerLCol is a framework that aims at providing personalisation effects by utilising the generated information during social collaboration and interaction. The result reveals the strength items as indicated by the selected components (PC1, PC2, and PC3). These components are related to three evaluated factors which are personalisation, social collaboration, and seamless design which ultimately reflect the objectives of the framework.

efractive error is a visual impairment that arises when the ocular anatomy hinders the proper focusing of light onto the retina, the light-sensitive tissue layer located at the posterior region of the eye. This condition poses difficulties in achieving clear vision. Refractive error stands as the prevailing kind of visual impairment. The objective of this study is to classify two surgical approaches utilized in the treatment of refractive defects. Two commonly performed refractive surgeries are Photo-Refractive Keratectomy (PRK) and Laser-Assisted In-Situ Keratomileusis (LASIK). Artificial Intelligence (AI) encompasses a specific branch known as Machine Learning (ML), which is the focal point of this investigation. ML is dedicated to the advancement and use of algorithms that possess the capacity to acquire knowledge from data and enhance their predictive capabilities without explicit programming. The present study employs sophisticated ML methods to classify different types of refractive defect surgeries using a dataset of 124 samples obtained from Al-Rabee Hospital in Iraq, specifically focusing on corneal topography data. Two ML approaches, namely K-Nearest Neighbor (KNN) and Artificial Neural Network (ANN), are employed to predict the kind of refractive defect surgery. The findings produced from the experiment demonstrated an accuracy rate of 90.32% for the KNN algorithm and a perfect accuracy rate of 100% for the ANN algorithm. Additionally, the KNN algorithm exhibited a sensitivity of 90% and a specificity of 90.54%. The study’s findings indicate that the ANN classifier outperforms the KNN classifier.

Renewable energy (RE) is getting more attention in solving the escalating global warming issue. However, the community has not been sufficiently educated about this fact. Exposure to renewable energy technology in Malaysia, especially for children, is still lacking, leading to a lack of awareness on the importance of renewable energy. Besides, children’s lack of knowledge about renewable energy and lack of interest in the field of science became problems in this study. Therefore, this study on effect of usefulness, user friendly, quality and user acceptance toward mobile application approach in introducing knowledge of renewable energy. The main software in developing the RE application consist of five components, i.e. introduction, video, game, quiz and news. Testing was carried out on selected children to evaluate children’s satisfaction in terms of using the application in learning RE. A pilot study was conducted on 30 children and the application model was validated by three experts and evaluated for its effectiveness through quantitative studies. Then, the mobile apps were tested on 77 9-year-old children with a quantitative research method to assess the level of knowledge acceptance and awareness of renewable energy. Results indicate that the children’s knowledge of RE increased with the use of this RE mobile application because RE information is delivered in the form of images, audios, and videos. More than 98% of the respondents agree that the application helps in understanding RE. The mobile application also successfully attracted the children’s interest in RE innovation and increased their awareness on the importance of RE.
Historical Prerequisites for the Formation of Legal Sovereignty of Russian Regions
Authors: Gordeev A. G. , Moon V. A. , Rumyantseva V. G.
Published: July 2024

The paper examines the theory of federalism in the political, administrative and territorial structure of the country. The collapse of the Soviet Union in the early 1990s caused the inclusion of the principle of national unity in the Constitution of the Russian Federation. The authors trace the dynamics of the division of powers between central and local authorities in Russia. The authors point out the importance of harmonizing the interests of the federal center and the regions, and the equal participation of all constituent entities of the Federation in state building as a guarantee of the unity of Russia. Building a competent balance in the distribution of powers between the federal center and the constituent entities of the Federation makes it possible to mitigate the contradictions that arise, which indicates the desire to ensure a balance of interests between the central government and the regions. The national authorities are working to increase the ﬁnancial autonomy of the regions, giving them the right to exercise control over their funds. This approach, taking into account the diﬀerences in mentality, culture, and needs of the regions, allows for a ﬂexible approach to the management of diﬀerent constituent entities of the Federation. Increased attention to regional speciﬁcs is a vector of the policy of the modern Russian supreme power. The desire for a reasonable balance between the central government and the regions reﬂects the historical evolution of the Russian state structure towards genuine federalism.
Custom as a Source of Russian Civil Law
Authors: Myakinchenko S. S.
Published: July 2024

In this paper, the author explores the historical signiﬁcance and complexity of legal customs in the formation of legal systems. The paper analyzes the evolution of a custom from the primary sources of law in ancient societies to its modern status, where their role, although important, is subject to certain limitations, is analyzed.

The paper highlights the understanding and application of the term «custom» in the context of modern civil legislation of the Russian Federation with an emphasis on the changes that occurred after the legislative reform of 2012. The study examines various ﬁelds of application of customs. Special attention is paid to the analysis of the role and place of international trade custom in civil law relations in the Russian Federation. Based on the opinions of experts and considering in detail the judicial practice of the International Commercial Arbitration Court at the Chamber of Commerce and Industry of the Russian Federation, the author concludes that international trade custom is a source of law, and it also falls under the concept of «custom» within the framework of Article 5 of the Civil Code of the Russian Federation. The study emphasizes the oral nature of a custom as a source of law, while not neglecting the importance of informal written forms such as Incoterms and UNIDROIT, as well as standard contracts Special attention is paid to the debatable topic of the relationship of customs with imperative and dispositive norms of legislation, as well as their place in the structure of the Civil Code of the Russian Federation. The author highlights the problem of insuﬃcient legislative regulation of customs and calls for their further research and systematization as a critically important element of the legal system.

Günümüzde iklim değişikliğinin, Dünya’nın geleceği ile ilgili en ciddi tehditlerden birisi olduğu herhangi bir şüpheye yer kalmayacak şekilde açıklığa kavuşmuştur. İklim değişikliğinin büyük oranda insan faaliyetleri tarafından tetiklendiği de bilinmektedir. Bu nedenle Paris Anlaşması’na taraf olan ülkeler, ortalama yüzey sıcaklığı artışının 2100 yılına kadar sanayileşme öncesindeki seviyeye kıyasla 2,0 ℃ ile sınırlandırılması konusunda anlaşmaya varmıştır. Bu hedef için gerekli sera gazı azalımının ekonomik büyümeden ödün vermeden sağlanabilmesi için yeşil büyüme modeli benimsenmiştir. Bu çalışmada ilk olarak gerçek yeşil büyüme (GYB) tanımı yardımıyla yeşil büyüme modelinin Paris Anlaşması’na uyumu sağlanmıştır. GYB’nin sağlanabilmesi başka bir deyişle 2,0 ℃ hedefine ulaşılabilmesi için yıllık karbon verimliliği artışının %5 olması gerektiği, çalışmada kullanılan küresel ekonomik büyüme projeksiyonu ve sera gazı salımı senaryosu göz önünde bulundurularak gösterilmiştir. Ardından Türkiye’nin GYB performansı, 2004-2020 yılları arasında seçilmiş ülkeler ve ülke grupları ile karşılaştırılmıştır. Türkiye’nin çalışma döneminde kaydettiği görece yüksek büyüme ve karbondioksit salımında sergileyemediği iyileşme nedenleriyle 2,0 ℃ hedefine uzak kaldığı sonucuna varıldığından, toplam enerji temininde teknolojik dönüşüme ihtiyacı olduğu değerlendirilmiştir.

Methods: This case-control study was conducted on 99 women with polycystic ovary syndrome and 96 infertile women for other reasons who referred to the infertility center of Ardabil city in 2022. The diagnosis of polycystic ovary syndrome in this study was based on the Rotterdam criteria. Mood disorders including depression and anxiety were determined based on the Beck standard test. After collecting the data, it was analyzed using descriptive and analytical statistics by statistical package for the social sciences (SPSS) software version 26.
Results: Most of the underlying diseases among them were related to bleeding with 71 cases (36.6%) and then related to hair growth with 43 cases (22.2%). Among the studied women, the rate of depression was 53 (27.3%) and 184 (94.8%) had a low level of anxiety. Among women with PCOS, 38 (38.4%) and among women without PCOS, 15 (15.8%) had depression. Statistically, there was a significant relationship between depression and PCOS.
Conclusion: The rate and severity of depression in PCOS patients was significantly higher than non-PCOS infertile patients.

Background: Ovarian cancer is the most lethal gynecological malignancy. The present study was therefore designed to determine the accuracy of IL-6 and CA-125 in the early diagnosis of malignant ovarian tumors. The aim of the study was to evaluate the predictive value of pre-operative serum IL-6 and CA-125 levels in identifying malignant ovarian tumors.
Methods: This cross-sectional study took place at BSMMU and NICRH in Dhaka, Bangladesh, from February 2022 to January 2023. It involved 94 women undergoing surgery for suspected ovarian tumors. The Mann-Whitney test was used to compare IL-6 and CA-125 levels between groups. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy were calculated to correlate serum markers with histopathological diagnoses. Statistical analysis used SPSS version 23.0 with significance set at p<0.05.
Results: The study involved 94 patients with ovarian tumors, where the mean age was higher in those with malignant tumors. The most common malignant histopathological finding was serous carcinoma (34%), while benign tumors often included endometriotic cysts (12.8%) and mucinous cystadenomas (10.6%). Elevated levels of IL-6 and CA-125 were significantly associated with malignant tumors (p<0.05). Both IL-6 and CA-125 showed high diagnostic accuracy in identifying malignant ovarian tumors when used alone or in combination, as indicated by receiver-operator characteristic curves.
Conclusions: Serum IL-6 shows higher sensitivity and specificity for detecting malignant ovarian tumors, both epithelial and non-epithelial, making it a valuable diagnostic tool alongside CA-125 in assessing suspicious ovarian masses.

Published: July 2024

Background: Working women, especially teachers, face unique challenges in managing health issues that impact their professional lives. Premenstrual symptoms (PMS) significantly affect their physiological, behavioural, and psychological well-being, potentially influencing their classroom performance. This study aimed to assess the severity and correlations of PMS across physiological, behavioural, and psychological domains among 100 working women teachers in Kalaburagi. It also explored associations with socio-demographic variables such as menstrual cycle duration and food cravings.
Methods: Data were collected using a cross-sectional correlation research design. Mean scores and standard deviations were calculated for physiological, behavioural, and psychological symptoms. Chi-square tests analysed associations between symptom domains and socio-demographic variables. Correlation analyses assessed relationships between symptom domains.
Results: Physiological symptoms scored a mean of 55.60 (SD=2.4, 70% of max. score), behavioural symptoms 45.32 (SD=2.5, 78% of max.), and psychological symptoms 46.90 (SD=2.3, 80% of max.). Overall mean score was 150.15 (SD=2.4, 75% of max.). Positive correlations were found between physiological and psychological symptoms (r=0.810, p<0.001), physiological and behavioural symptoms (r=0.729, p<0.001), and psychological and behavioural symptoms (r=0.627, p<0.001).
Conclusions: This study highlights the prevalence of PMS among working women, especially teachers, and their potential impact on professional performance and emotional well-being. The findings underscore the need for effective detection and management strategies to enhance the quality of life and work efficiency of affected women. Targeted interventions and workplace support can improve personal and professional outcomes for women experiencing PMS.

Background: AUB is the most common presentation in the reproductive age group. Many females suffer from AUB and its related effects. A study on the effectiveness of an easily available drug (ormeloxifene) with an easy dosing schedule was done and its wonderful role in controlling the symptoms and improvement of quality of life of a female with no financial burdens and surgical morbidity was studied.
Methods: A hospital based prospective observational study was conducted among women attending the outpatient clinic of OBG department at Dr Somervell Memorial CSI Medical College, Karakonam, Trivandrum district.
Results: Total 50 women with AUB took part in the study. 62% had menstrual duration of <7 days with regular cycles (84%). 86% of them had history of passage of clots. 48% of them had dysmenorrhea. Efficacy of ormeloxifene was assessed by using PBAC score and haemoglobin level measurement. A repeated measures ANOVA with a Greenhouse-Geisser correction determined mean PBAC score differed significantly between months. Post hoc analysis with a Bonferroni adjustment revealed PBAC score was statistically significantly decreased from pre-intervention to 3 months to 6 months. There is statistically significant difference with respect to haemoglobin level improvement.
Conclusions: Ormeloxifene is an excellent drug in controlling AUB as evidenced by the PBAC score and haemoglobin levels. Ormeloxifene has better compliance and acceptability. It is cost effective with a simple dosage schedule. A significant decrease in the menstrual blood loss and marked improvement in the hemoglobin concentration.
Rare presentation of esophageal atresia with supra-esophageal atresia: a case report and management challenges
Authors: Suhandri Wiwin , Hericos Muhammad
Published: July 2024

Esophageal atresia (EA), often regarded as 'the epitome of modern surgery', typically presents with tracheoesophageal fistula (TEF) and occurs in about 1 in 2400 to 1 in 3000 newborns, frequently accompanied by other congenital malformations. Rarely, EA is associated with congenital esophageal stenosis (CES), a condition first identified by Spitz. EA and TEF result from the incomplete development of the esophagus and trachea, with polyhydramnios in the third trimester being a potential indicator. This case study described a 43-year-old multiparous woman who, during an antenatal care examination, was found to have a fetus with abnormalities and excessive amniotic fluid, necessitating two amnioreduction procedures. Despite the interventions, the fetus exhibited signs of supra-esophageal atresia, leading to an elective cesarean section. The newborn, a girl with a birth weight of 3200 grams and an Apgar score of 5/6, could not be fitted with an orogastric tube, although karyotyping showed no chromosomal abnormalities. The discussion highlights the association of EA with various tracheobronchial anomalies and emphasizes the need for preserving the native esophagus in cases of CES. Gastroesophageal reflux disease (GERD) is common in EA patients, often requiring long-term follow-up and possible antireflux surgery. The case underscores the importance of diligent monitoring and intervention in high-risk pregnancies, with regular ANC examinations and accurate diagnoses being crucial for effective management.
