En el presente artículo realizaremos una descripción de una de las investigaciones que llevamos a cabo desde el Área de Actividades Interdisciplinarias sobre Conductas Discriminatorias del Ministerio Público Fiscal de la Ciudad Autónoma de Buenos Aires. Nos centraremos en el vínculo entre la radicalización de acción y de opinión (McCauley; Moskalenko, 2017) presente en los jóvenes y el impacto que tienen las nuevas tecnologías de la información y de la comunicación para tratar de entender algunas de las aristas del fenómeno (Han, 2021; Gurri, 2023). Y, asimismo, indagaremos en un aspecto central de cómo funcionan las redes sociales en la actualidad: los algoritmos de recomendación (Deepjyoti; Mala, 2022). Tomaremos como ejemplo un caso en particular que nos permitirá mostrar los mecanismos internos de radicalización y extrapolar ciertos patrones de conducta que observamos en la actualidad. Durante la investigación se pudo descubrir que un joven argentino no solo realizaba publicaciones de odio en sus redes sociales abiertas, sino que también participaba en grupos extremistas online en redes encriptadas.

Research on the spatial distribution of garden landscape based on the optimization of K-means clustering algorithm
Authors: Chen Yu 
Published: August 2024

Abstract
With the advancement of national urbanization, urban and rural construction have entered a brand new stage, and ecological civilization and circular economy have become the main themes of contemporary sustainable development. In this paper, the K-means clustering algorithm optimizes the spatial distribution of garden landscapes in urban parks from the perspective of a sponge city, with the ultimate goal of maximizing the comprehensive benefits of ecology, economy, and society. The case study of Yunlu Park in Yunshan Community, Fengze District, Quanzhou, is selected to elaborate on the design principles, structural characteristics, planning, and design methods of urban parks from the perspective of ecological cities. The results indicate that the K-means clustering method is capable of determining the optimal values for POI mixing degree and DPAT. The optimal values for POI mixing degree and DPAT are 4.2243 and 4.0415, respectively. Once these values reach their peak, they start to exhibit a mutual promotion relationship. This method reflects the spatial layout of parks and green spaces more accurately, and it has universal applicability. It can also provide a reference for the spatial layout research of other facilities.
A Study of Folk Culture in Francophone Central Africa Incorporating Deep Learning
Authors: Cai Yali 
Published: August 2024

Abstract
Through the theoretical analysis of folk culture in French-speaking countries in Central Africa, six-dimensional features of folk culture in non-French-speaking countries are summarized, and the folk culture database of French-speaking countries in Central Africa is constructed based on a web crawler. Fusing scene region features with image color and texture features, an Extreme Learning Machine algorithm carries out the classification to realize the construction of a folk culture classification model based on deep learning, and the cross-entropy loss function and Adam optimizer are used respectively to optimize the above-constructed model. The relevant parameters, training set, and test set are determined, and an example analysis of non-Chinese folk culture from the perspective of deep learning is carried out. It is found that the accuracy of non-folk culture classification of the model after Adam and cross-entropy optimization is significantly higher than that of the CNN model, with an average of 0.03~0.04, indicating that after optimization, the model can more comprehensively reflect non-French-speaking countries’ folk culture information and features in images. In addition, there are fewer symbols of non-French-speaking folk culture in the image modality, such as religious beliefs (17, 4.57%) and music and dance (32, 8.60%), which is because it is difficult to represent this type of folk culture with images. This paper fully illustrates the prospects for the application of deep learning models in the study of folk culture in French-speaking Central Africa, which can contribute to the development of digitization and informatization of folk culture in French-speaking Central Africa.

Abstract
The expansion of visual communication design in public art makes the scope of visual communication wide. This new art form reflects the cross and integration of disciplines but also makes the form of public art in our life richer, and people can get more beautiful enjoyment. Research on the fractal algorithm in the escape time algorithm studied the Julia set in different function conditions of the fractal graph of the change and the function of different indices of the joint. The fractal graph obtained a colorful, more tense structure. Subsequently, it is applied to public art design, and after testing its performance, the fractal design of visual communication is combined with the IPA model to explore the practical effect of the fractal design in public art design. The results show that the improved fractal algorithm proposed in this paper increases the pattern generation rate from 61.5% to 92.6%. The fractal dimension measurement of 15 typical batik patterns shows that more than 85% of the batik patterns have an average value of more than 15000.

Published: August 2024

Abstract
The classification of jade grade has always been a very critical part of the jade industry, and improving the accuracy of jade grade classification is of great significance to the sustainable development of the jade industry. The study constructs a mineral identification classification model based on Raman spectroscopy + PCA through Raman spectroscopy and PCA principal component analysis and analyzes the data of jade grades and constituents. The actual performance of this paper’s model is explored by comparing its effectiveness with other algorithmic models in jade classification and the accuracy of classification parameters. The model in this paper is feasible in classifying the four grades of Hetian jade (seed material, gobi material, shanliushui material, and shanmu material). Green dense jade’s main minerals are <unk>-quartz and a few other minerals, including albite, hematite, graphite, and tourmaline. The main compositions of the sample jade are SiO2, Al2O3, and K2O. The overall accuracy of this paper’s model in classifying Xinjiang Hotan jade grades is 97.9%, which is significantly higher than that of the KNN classification algorithm and SVM classification algorithm. The total accuracy of this paper’s model on each parameter of jade grade is 85, which is higher than the 60 of the KNN algorithm and the 62 of the SVM algorithm, and the classification accuracy grade is high.

Abstract
In the context of cultural and tourism integration, the study of Shanxi folk songs’ dissemination path and multicultural integration has important practical significance and far-reaching influence. Through an overview of cultural and tourism integration in Shanxi folk songs, the characteristics and mutual influence of the two are summarized. The digital communication path of Shanxi folk songs under the background of cultural and tourism fusion is explored by constructing a database of Shanxi folk songs, an automatic evaluation system of sight-singing, and an offline communication mode, respectively. The results show that the response time of the database remains within 4 seconds when the number of users reaches 2000. In the analysis of the note alignment module, the F1 data value of this paper’s method is 13.42% higher than that of the LSTM model, and this paper’s model is more suitable for the note alignment of Shanxi sight-singing. In the offline communication model, the construction of facilities has the greatest influence on the communication effect, with a regression coefficient of 0.812, a T-value of 35.421, and a P-value of 0.003. This study not only enriches the cultural life of the people and enhances the sense of identity of the national culture but also promotes the inheritance and development of the culture of Shanxi folk songs and contributes positively to the prosperity of the culture and tourism industry in the Shanxi region.
Gerakan Hak-Hak Disabilitas di Bali: Analisis Fenomenologi dalam Penyebaran Norma Internasional Hak-Hak Disabilitas
Authors: Wiranata I Made Anom 
Published: August 2024

The Convention on the Rights of Persons with Disabilities (CRPD) ratified by Indonesia in 2011, presents the perspective of the fulfillment of the rights of persons with disabilities. The process of internalizing disability rights norms at the domestic level does not occur linearly, but through the struggles of the disability rights activists in their respective regions. Taking place in Bali, this study investigates the motivations and causes of the involvement of disability rights actors in disseminating disability rights norms. By using a transnationalism theory and phenomenological methods, this study finds that the spread of international norms on disability rights in Bali occurred as a social movement that had grown before the ratification of the CRPD. There is an open interaction between local, national and international actors. The self-struggle against discrimination and the interaction of movement actors in Bali with international volunteers who have a cosmopolitan consciousness, gave birth to the movement agency. CRPD provides an opportunity and direction for movement actors to advocate local regulations for the fulfillment of disability rights. In their social environment, they build awareness to the persons with disabilities and their families, as well as showed the wider community that persons with disabilities have the competence to be independent.
Membranous tonsillitis: Aetiology, prevalence and prescribing patterns in patients with upper respiratory tract infection
Authors: SEÇILMIS YILMAZ 
Published: August 2024

Background
Membranous tonsillitis is one of the most common forms of acute tonsillitis in childhood. Although many different microorganisms may cause this disease, clinicians generally consider bacterial agents as a possible cause and prescribe a penicillin-group of antibiotic. This study aimed to determine the aetiology of membranous tonsillitis and prescribing errors. In addition, we investigated the effectiveness of epidemiological, clinical and laboratory parameters and their role in guiding treatment.

Methods
We did this retrospective study at the paediatric emergency department of a tertiary referral hospital including 423 outpatient children aged 0 to 18 years diagnosed with membranous tonsillitis.

Results
Group A beta-haemolytic streptococcus was found in 132 (31.2%) patients, Epstein–Barr virus (EBV) in 103 (24.3%), and other viral aetiologies in 188 (44.4%). The prescription rate of antibiotics in the EBV-positive group was 27%, and Downey cells were seen at a rate of 98% in this group. Only 7% of patients with a positive throat culture were started on appropriate antibiotics.

Conclusion
EBV and group A beta-haemolytic streptococcus were the most common causes of membranous tonsillitis. Throat culture and peripheral blood smears are the most useful tests for paediatric emergency clinicians; these are fast and can help ensure correct diagnosis and guide treatment in almost all patients.

Получены новые ПАВ на основе утилизации отходов производства капролактама. Для получения ПАВ кубовые остатки бензойной кислоты сульфировали концентрированной серной кислотой в присутствии катализатора Al2(SO4)3 и продукт реакции этерeфицировали высшими одноатомными спиртами. Изучены поверхностная активность и пенообразующая способность полученных новых ПАВ в водных растворах. Показано, что с ростом длины алифатического углеводородного радикала поверхностная активность ПАВ производных бензойной кислоты увеличивается. Установлено, что имеет место хорошая корреляция между пенообразующей способностью и поверхностной активностью изученных ПАВ. Показано, что устойчивость пен в значительной степени определяется взаимодействием молекул ПАВ и добавок в монослое.
New surfactants were obtained based on the utilization of caprolactam production waste. To obtain surfactants, the cubic residues of benzoic acid were sulfonated with concentrated sulfuric acid in the presence of an Al2(SO4)3 catalyst and the reaction product was etherified with higher monatomic alcohols. The surface activity and foaming ability of the obtained new surfactants in aqueous solutions were studied. It has been shown that with an increase in the length of the aliphatic hydrocarbon radical, the surface activity of surfactants of benzoic acid derivatives increases. It has been established that there is a good correlation between the foaming ability and the surface activity of the studied surfactants. It has been shown that the stability of foams is significantly determined by the interaction of surfactant molecules and additives in the monolayer.

В статье предложен новый способ получения кремнийорганических продуктов в присутствии экологически чистой наноглины. Методом ИК - Фурье спектроскопии изучено радиационно-химическое превращение углеводородов сырой нефти в гетерогенной системе под действием γ-облучения при комнатной температуре. Абсолютно новыми являются результаты, свидетельствующие о том, что при радиолизе нефти, с высоким содержанием ароматических углеводородов на поверхности наноструктирированного бентонита в области поглощенной дозы 57≤ D ≤ 259кГр происходит образование различных кремнийорганических продуктов. Такие изменения свидетельствуют о вхождении углеводородов сырой нефти в межслоевое пространство и их взаимодействии с наночастицами бентонитовой глины. Получены гибридные наноструктуры, содержащие углеводороды нефти.
The article proposes a new method for obtaining organosilicon products in the presence of environmentally friendly nanoclay. The radiation-chemical transformation of crude oil hydrocarbons in a heterogeneous system under the action of γ-irradiation at room temperature was studied by FT-IR spectroscopy. Completely new are the results indicating that during the radiolysis of oil with a high content of aromatic hydrocarbons on the surface of nanostructured bentonite in the region of the absorbed dose of 57≤Dγ≤259 kGy, various organosilicon products are formed. Such changes indicate the entry of crude oil hydrocarbons into the interlayer space and their interaction with bentonite clay nanoparticles. Hybrid nanostructures containing petroleum hydrocarbons have been obtained.
