The aim of this study was to present the experiences of teaching Greek traditional dance to young adults with DS and moderate mental retardation as well as to evaluate the learning of the kinetic form of the dances by the participants. A total of 22 individuals aged 20 to 30 years old who had been diagnosed with DS and mild mental retardation participated in the survey. The programme lasted 12 weeks with a frequency of 3 times per week. The duration of each lesson was 60 minutes. The kinetic form of nine Greek traditional dances was taught. The teaching approach was carried out taking into account the specificities of the participants. The evaluation of the learning was carried out by three Physical Education teachers with specialization in Greek Traditional Dance and long experience in teaching people with special abilities. The Graded Criteria Scale for the Evaluation of Greek Traditional Dance by Pitsi, Diggelidis, & Filippou (2013), as adapted for populations with disabilities by Kamilaki (2021), was used to assess learning. From the analysis of the data obtained from the evaluations of the three judges, the following results emerge: (a) people with DS and moderate mental retardation have the ability to participate and learn Greek traditional dances as long as the teaching approach is adapted to their abilities; (b) dances should be simple and without much complexity; (c) the instrument that gives the rhythm should be clearly audible; (d) people with DS enjoy and express themselves by participating in dance activities.

The United Nations Convention on the Law of the Sea (UNCLOS) of 1982 is a significant international legal document that serves as the foundation for managing maritime zones and oceans. It establishes the sovereignty and jurisdictional rights of nations over maritime areas such as territorial waters, contiguous zones, exclusive economic zones, and continental shelves, while also setting principles for resource exploitation, environmental protection, and maritime security. UNCLOS provides mechanisms for dispute resolution through legal and diplomatic channels, contributing to the maintenance of legal order at sea. Vietnam is among the countries that have applied UNCLOS to define maritime sovereignty, safeguard maritime rights, and address disputes in the South China Sea. The convention has provided a solid legal framework for Vietnam to develop maritime management policies, promote international cooperation, and protect national interests in the maritime sector. Given its crucial role in regional stability, UNCLOS continues to make significant contributions to fostering cooperation and ensuring maritime security on a global scale.

This scientific article focuses on the setbacks associated with classroom management in Goma Secondary schools. It comes to provide some strategies that teachers should consider in their everyday teaching activity.
However, teaching is the most complex activity considering the different tasks to carry out during the process. Therefore, it is very important to teachers to be aware of those setbacks in order for them to be able to address them successfully.
Most of the teachers face uncountable challenges in managing the learners’ behaviour, the time, the teaching materials as well as the different activities in the classroom, and those are the main setbacks they face. Therefore, this article will shed a light to help teachers in dealing with those setbacks and overcoming them successfully in their noble career.

Most English-speaking people are unaware of the vast differences between British English and American English. This article is designed to enlighten the reader and the learners of English language on these differences and briefly explain how these differences should not constitute a hindrance to communication.
As a matter of fact, this article is intended to show a number of main areas of differences between British English and American English in order to help learners of English with tips and strategies to overcome their fears in practicing this foreign language.
The language that Americans and British share is spoken differently in the two locations, but understandable by both groups of speakers. Therefore, it also needs to be understood by all hearers regardless of the version used. In other words, English language learners are encouraged to make efforts toward understanding either of these two accents, i.e. British English and American English, and thus eliminate their fears according to which American English is more difficult than British English or the other way round.

This study takes Guangxi Science & Technology Normal University as a case to investigate the levels of class autonomous management and adaptability, as well as the effects of gender, school, and holding a class leadership position on the class autonomous management and adaptability of first-year students. A sample of 322 first-year students from the 2024 cohort was selected using simple random sampling, and data was collected through a questionnaire survey. The study conducted a multidimensional analysis based on the theories of subjectivity education and social adaptability. The results indicate that both the class autonomous management and adaptability of first-year students at Guangxi Science & Technology Normal University are at a moderate level, with differences found in class autonomous management and adaptability due to gender, certain schools, and holding a class leadership position.

The study was conducted in a public building situated in Tepetlixpa, State of Mexico. The building was previously used as a municipal market but is currently underutilized. As part of the 'Tepetlixpa Tourist Corridor' project, it needs to be converted into a handicrafts market. A bioclimatic analysis was carried out on the interior of the building in order to control the temperature. The building is situated in a temperate climate zone with minimal fluctuations, according to the Köppen-García classification. It is classified as semi-cold in terms of bioclimatic grouping.
Solar control devices were proposed based on a solar analysis, which involved two stages. The first stage studied the incidence of the sun's rays inside the building using stereographic graphics. This determined the critical dates and hours of sunlight on the building's facades, as well as the ideal orientations for placing control devices to block direct sunlight.
The second stage involved creating a scale model of the building, which was evaluated in the heliodon of the Bioclimatic Architecture Laboratory at Universidad Autónoma Metropolitana, Azcapotzalco Campus. This analysis enabled us to observe the solar trajectory at latitude 19°03' north, longitude -98°82' (solstices and equinoxes) to verify the effectiveness of the proposed solar control devices.
We then used the Design Builder ® software (DesignBuilder, 7.0.2.004) to evaluate the thermal behavior inside the building, before and after the implementation of solar control devices to achieve passive temperature control and avoid the implementation of mechanical systems; evaluations were carried out in the most critical months: January and May, whose results indicate good thermal behavior with the proposed devices.
