DRAMATIC TRADITIONS IN DARGINIAN FOLKLORE
Authors: Э.М. Курбанова
Published: October 2024

Даргинская литература, как и литературы других народов Дагестана, возникла на основе диалектического слияния художественного опыта народа, хранимого в его фольклоре. Богатый фольклор даргинцев не знал драмы в прямом значении этого слова, хотя разнообразные драматические элементы наличествовали в календарных народных обрядах, а также эпосе и лирике.

Dargin literature, like the literature of other peoples of Dagestan, arose on the basis of a dialectical fusion of the artistic experience of the people stored in their folklore. The rich folklore of the Dargins did not know drama in the direct meaning of this word, although various dramatic elements were present in calendar folk rituals, as well as epics and lyrics.
Comparison of mechanical and flammability properties of thermoplastic
and thermoset matrix glass fibre woven fabric composites
Authors: ARI ALİ , KARAHAN MEHMET , KARAHAN NEVIN , YEDEKÇİ BUŞRA
Published: October 2024

This study aims to examine the mechanical and burning properties of composites made from twill (0°/0° and 0°/90°
orientations) and plain fabrics using hybrid yarns produced by combining glass and polypropylene yarns with interwoven
and intermingled methods. The properties of interwoven and intermingled hybrid fabric composites were compared with
thermoset composites. Each composite (56% glass fibre content) plate is produced by combining eight fabrics with the
same parameters using the press moulding technique. The effects of yarn and fabric weaving types on the results were
examined in detail. When the results are examined, the breakage of glass fibres in intermingled hybrid yarns negatively
affects the strength results. Therefore, composites made with intermingled hybrid yarn types and plain weave types of
fabric had the lowest tensile strength value (132 MPa). The composite of twill woven fabrics produced with interwoven
yarns arranged in 0°/0° orientation had the highest tensile strength of 315 MPa, and these results were very close to
those of thermoset composites. Although the 0°/90° oriented twill composite showed a 2.3 times lower tensile strength
value than the 0°/0° oriented twill composite, it had a 7.7 times higher value when bending strength values were taken
into account. The main reason for this is that glass fibres contribute to the warp and weft directions. It has been observed
that the composite consisting of plain fabrics woven with commingled hybrid yarns had the highest impact resistance.
Additionally, when the combustion results were examined, it was concluded that the type of yarn and fabric weaving
affected the burning rate. The slower combustion of hybrid commingled yarn composites resulted from fibreglass
breakage during yarn production. These findings provide valuable insights into optimizing composite materials for
specific applications, considering factors such as weaving pattern, fibre orientation, and mechanical performance.
Image evaluation and analysis of fabric with a geometric motif in dress
style design
Authors: SONG YING , ZHANG NING , WU TONG
Published: October 2024

To explore the differences in sensory imagery produced by different geometric patterns and dress silhouettes, this study
selected and extracted 4 different types of geometric patterns and 4 typical dress silhouettes as research carriers,
determined the research samples through cross-combination, and used 8 pairs of sensory word pairs as research
semantic space. Consumer sensory evaluations of the dress samples were collected through a survey questionnaire.
The results were analysed using SPSS26.0 software, which showed that three sensory factors affect the appearance of
the dress style. According to their main characteristics, they can be named as personality factor, temperament factor,
and style factor. In terms of the silhouette of the dress, the neat and regular geometric pattern is most affected by the
silhouette of the dress, while the other three types of geometric patterns are relatively weak. In terms of geometric
pattern rules, different geometric patterns have different effects on the overall appearance of the dress after being
combined with the silhouette of the dress, and some dresses play a certain role in all three factors.
Multidimensional analysis of textiles coated with electroactive polymers
for actuators
Authors: Aileni Raluca Maria , Stroe Cristina
Published: October 2024

This paper presents a multidimensional analysis of textiles coated with conductive polymers for actuators. The purpose
of using multidimensional scaling analysis is to compare similarities and dissimilarities between conductive textiles
obtained through conductive polymeric film deposition to observe the optimal value for electrical resistance and to select
an adequate method to achieve conductive fabric using different polymers (polyethylene glycol, polyvinyl alcohol or
polyvinylidene fluoride) and metal microparticles (copper or nickel). The multidimensional analysis is based on mapping
a series of material properties from a proximity matrix (similarities or dissimilarities) between these properties.
Multidimensional scaling allows rebuilding the exact map of the values (within approximately a symmetry or rotation). To
fit dissimilarity or similarity matrices for multiple variables into one common space estimating the weight parameters for
each variable, the INDSCAL model (individual differences multidimensional scaling) was used.

discuss the exquisite textile techniques and artistic features of the Qing Dynasty Lu-silk Apron and analyse the social
system, humanistic sentiment, cultural symbolism, and intelligent thinking at multiple levels through style types, size
analysis, colour interpretation, pattern expression techniques, and skill production. In this article, we also used the
popular simulation technology to restore the Qing Dynasty Lu-silk Apron and provide a new way and path to study other
ancient costumes.
Antibacterial Power of Lemon Essential Oil, Ginger And Their Synergy With Neem Vegetable Oil On Mastitis Pathogenic Germs Dairy Cows From The Poro Region In Ivory Coast
Authors: KOUAHO FH , A. TOURE A. TOURE , GOURO AS
Published: October 2024

Gas chromatography-mass spectrometry analysis of essential oils of (Citrus limon, Zingiber officinalis and Azadirachta indica vegetable oil), purchased, identified 32.80%, 42.40% and 47.10% of its constituents. This study consisted of evaluating the antimicrobial performance of some EOs obtained from three medicinal plants, considered to have a great bacterial effect. This is in order to standardize their use to apply them as an alternative remedy to antibiotics in the face of the advance of resistant bacteria and the failure of antibiotic therapy. The essential oils of these plants were tested alone or in combination on nine pathogenic microbial strains from cows suffering from mastitis and resistant to certain antibiotics, namely: four Gram (-) bacterial strains (Pseudomonas aeruginosa, E. coli ATCC25922, E. coli, Klebsiella spp) ; five Gram (+) bacterial strains (Staphylococcus aureus, Micrococcus spp, S. aureus ATCC19213, SCN (S. lentus and S. xylosus)); and E. coli ATCC25922, S. aureus ATCC19213 as reference strains. Reasonable antimicrobial activities of the studied EOs were observed on some of the germs tested. All the strains tested are sensitive to concentrations less than or equal to 100μg.ml -1 of essential oil. Enterobacteria (Escherichia coli, Klebsiella spp) are resistant to standard antibiotics with the exception of Colistin, which have been shown to be sensitive to all essential oils studied. This observation applies to Gram-positive cocci (Staphylococcus aureus, Micrococcus spp, Staphylococcus lentus and Staphylococcus sylosus) which are very sensitive to the oils studied but resistant to three types of standard antibiotics (Ampicillin, Colistin and Penicillin). The CMB/MIC ratios of Zingiber officinalis and Citrus limon oils have a bacteriostatic action while that of the combination of EO (Zingiber officinalis, Citrus limon and Azadirachta indica oil ) are bactericidal on all bacterial strains tested. There was no significant difference between the MIC and MBC values of the essential oil resistant strains. As a result of the study, an idea could be proposed for the development and upgrading of a new generation of combination of natural antimicrobial agents that can be used in humans and animals against infections with commonly used antibiotics.

Authors: Agbeshie Abraham , Sawyerr Naa Omai , Quansah Sarah
Published: October 2024

This study explored the potential of garment painting as a textile decorating method and by extension an additional source of income generation in textile production practice. As a developing country, the capability of generating local products through local means of manufacturing are commended in the Ghanaian society and highly promoted among its diverse communities. Surface designing is an integral part of Ghana’s textile and garment industry and has historically incorporated techniques such as stamping, tie and dye, resist dyeing and direct printing. In recent times, however, innovations such as garment painting has emerged to give a new meaning to clothing decoration and has set the trend for local fashion consumption, especially among the youth. As a result, garment painting is rapidly growing as a commercially viable business for the textile and garment industry in the country. This study discusses the innovation of garment painting and highlights its implication on the future of the local textile and garment industry. It has been established from the study that fabric painting is a creative way to transform plain fabric surfaces with unique designs. Additionally, this method of decorating fabrics is unique and a one-stop process that will assist in revolutionalising the local textile industry in the face of stiff global competition from factory-printed fabrics.
Dress Fashion Politics of Ghanaian Presidential Inauguration Ceremonies from 1960 to 2017
Authors: Essel Osuanyi Quaicoo
Published: October 2024

Presidential inaugurations are statutory in Ghana, but what a president wears during his inauguration are non-statutory, yet, it is a salient visual communicative apparatus that pulls the strings of patriotism, nationalism and fosters a sense of belongingness. In an attempt to throw light on the dress fashion politics of president-elects, the study examined their chronological inaugural dress fashion choice from 1960 to 2017 in order to establish the trend of dress cultural identity they have portrayed during their respective inauguration ceremonies. Using census sampling technique, the sample consisted of all democratically elected Presidents from the first to the fourth Republic. The instrumentation used were motion pictures, archival records and images of the president-elects during their respective inaugural ceremonies. Motion pictures and images gathered were subjected to semiological analysis. The study revealed that seven of the eight president-elects selected their inaugural ceremony dress fashion from the repertoire of Ghanaian fashion classics to signal their Ghanaian dress cultural identity. Their dress fashion, fabric weaves, pattern symbolisms and construal of colours used were sourced from the cultural knowledges of multi-ethnic nationalistic ideological experience and mindset with the aim of fostering unity, nationalism, and display of their Ghanaian identity. Though their ethnic cultural backgrounds and geographical locations partially influenced their dress fashion choice for their inaugural ceremonies, the nationalistic purview and psychologisation of the inauguration atmosphere took precedence, hence the blend in terms of fashion classics and fabric used. The study recommended that parliament must consider making presidential dress fashion choice statutory due to its cultural, social, political and economic factors for the development of textiles and fashion in Ghana.

Authors: FREYER Eckhard , LISHCHYNSKY Ihor LISHCHYNSKY , LYZUN Mariia
Published: October 2024

In wartime, the role of international assistance and foreign direct investment in ensuring Ukraine’s economic sustainability has increased. The study examines foreign direct investment (FDI) and international financial assistance as key factors contributing to economic growth. The structure and dynamics of international aid in Ukraine are reviewed. A regression analysis was conducted to determine the impact of international aid (particularly, international development assistance) and FDI on the gross domestic product of Ukraine. The results of the study show a positive impact of both performance parameters, while their values are significant and significantly higher than zero. However, FDI flows have a greater impact on GDP than international development assistance. This suggests that international aid is important for maintaining stability, while FDI has a more significant long-term impact on Ukraine’s economic development, especially in the context of integration into the global economy and attracting innovation.

SPACE SYNTAX METHOD APPLIED TO INFORMAL SETTLEMENTS: CASE OF BHAR LAZREG, IN TUNIS
Authors: Khiari Noura
Published: October 2024

La recherche urbaine est essentielle pour appréhender certains phénomènes urbains complexes et orienter les actions visant à les traiter. Le phénomène de périurbanisation et des quartiers informels en sont un exemple. Ces quartiers ne cessent de proliférer en Tunisie depuis plus d’une cinquante d’années et surtout après la révolution de janvier 2011. Ces extensions illégales prennent forme aux alentours de toutes les grandes villes de la Tunisie et ce, malgré toutes les tentatives pour les contrer et les freiner en passant des actions de démolitions jusqu’aux récentes opérations d’intégration qui restent partielles et insuffisantes. C’est pour cette raison, qu’ils nécessitent une étude minutieuse visant à en démontrer leur complexité et à fournir de nouveaux éléments à intégrer dans les futures interventions. Ce travail s'inscrit dans cet optique, faisant suite à un travail de recherche mené dans le cadre d’un doctorat en Architecture. Cette étude se base sur l'analyse des configurations spatiales d'un quartier informel situé dans la banlieue nord de Tunis, plus précisément à Bhar Lazreg qui était auparavant une vaste terre agricole et qui n’a cessé d’être grignoté par ce type d’habitat depuis les années 1980. La méthode choisie pour l’analyse de ce quartier se base sur l'application des principes de la syntaxe spatiale, développée par Bill HIILIER. Cette méthode permet de modéliser et d’analyser des relations spatiales révélatrices des comportements sociaux. Ainsi, elle ne dissocie pas la forme du comportement qui est déjà inscrit en elle. Il s’agit donc d’étudier les relations entre les composantes du système urbain à travers une déclinaison manuelle. Les résultats trouvés ont révélé une structure organisationnelle de ces espaces et une manière de vivre spécifique qui ne peuvent être exclues du processus de conception de solutions pour cette catégorie de la population. Ces découvertes soulignent l'importance d'une approche nuancée de la planification urbaine, qui reconnaît et intègre les réalités complexes des quartiers informels. Ainsi, cette recherche fournit des contributions à l'urbanisme et à l’architecture garantissant que les solutions proposées sont non seulement techniquement viables, mais également socialement inclusives et reflètent les expériences vécues des habitants, favorisant ainsi des environnements urbains plus résilients.

Sengon wood sawdust is a wood industry waste the quantity of which is increasing because of the high market demand of the wood. This condition demands innovation in waste processing. Microcrystalline cellulose is pure cellulose obtained from the hydrolysis of α-cellulose. This research aims to fabricate and characterize microcrystalline cellulose from Sengon wood sawdust. The initial stage was carried out to break lignocellulose bonds through the delignification process using 2% NaOH, followed by hydrolysis of α-cellulose with 4N HCl (1:40) at 80 °C. This acid treatment aims to obtain a crystalline form of cellulose by removing the amorphous part. SEM micrographs show a smooth surface with few holes and spherical fibers. XRD analysis revealed the cellulose type I structure of MCC with a crystallinity index of 33.8% due to acid hydrolysis treatment. Chemical treatment causes the loss of the hemicelluloses and lignin, as confirmed from the FT-IR analysis results, and higher thermal stability of microcrystalline cellulose, as found by the DSC analysis.

The research and development of new materials that are not only functional, but also ecologically acceptable, is a key aspect in many branches of industry. Such materials include elastomeric composites reinforced with alternative fillers such as cellulose. Cellulose is a renewable and biodegradable alternative to traditional fillers used in elastomeric composites. The main disadvantage of this biopolymer is its poor compatibility with the hydrophobic matrix and low mechanical strength. The free hydroxyl groups on the cellulose surface allow for a wide range of surface modifications. In this work, we focused on the chemical modification of cellulose using two different silanes due to their ability to react with the free hydroxyl groups on the surface of cellulose. This work deals with the characterisation of thermal stability of surface modified cellulose used as filler in polymer composites. Cellulose modified in this way was used in the amount of 45 phr as a filler in the preparation of elastomeric composites with natural rubber (NR) matrix. The NR composite filled with surface modified cellulose was characterized by TG/DSC, IR spectroscopy, XRD and scanning electron microscopy.

Flax reinforced epoxy (F-Ep) composites were prepared by the compression moulding technique, varying the fiber content (0, 25, 35 and 45 wt%). The free vibration test was performed on the neat epoxy and F-Ep composites to understand their dynamic characteristics, and results showed that natural frequency and damping factor of the F-Ep composites increased with an increase in the fiber content. The F-Ep composite (45F-Ep) that exhibited better damping was selected for performing the drilling operation. Factors such as spindle speed (rpm), feed rate (mm/min) and drill point angle (degree) were chosen as input parameters and the tabulated set of experiments were in accordance with Taguchi’s design of experiment. The response measured was thrust force and the obtained values were found in the range of 19.66 to 50.75 N. The minimum value of thrust force was achieved when the F-Ep composite was drilled at high spindle speed (3000 rpm), with a feed rate of 75 mm/min using the drill point angle of 118°. ANOVA analysis showed that the developed regression model was significant and thrust force was mainly influenced by the spindle speed. Mathematical models were developed for drilling F-Ep composite using response surface methodology (RSM) and adaptive neuro fuzzy inference system (ANFIS) and compared for their efficacy.

Published: October 2024

Breast milk is the best source of nutrition for babies, providing nutrients, growth factors and antibodies in sufficient quantities for baby nutrition. However, the lack of breast milk is one of the causes of not achieving exclusive breastfeeding coverage in several areas. One effort that can be made to increase breast milk production is through oxytocin massage. Oxytocin massage is a massage carried out along the spine (vertebrae) to the fifth-sixth ribs. This massage is done to stimulate the oxytocin reflex or breast milk reflex. Mothers who receive this oxytocin massage will feel more relaxed. The method used in this community service activity is through providing materials and training on oxytocin massage to 30 cadres in the Pegerngumbuk Village area, Wonoayu District, Sidoarjo Regency. The results obtained from this activity were an increase in cadres' knowledge about oxytocin massage and almost all cadres were able to do oxytocin massage. So that after this training activity cadres can apply oxytocin massage periodically to breastfeeding mothers in their area and teach these skills to the families of breastfeeding mothers.

Cholesterol is one of the essential molecules in humans. An imbalance in cholesterol levels in the body, such as high levels of triglycerides and low-density lipoprotein (LDL) or total cholesterol, can contribute to one of the leading causes of death in Indonesia. Diseases caused by high cholesterol levels include cardiovascular diseases, atherosclerosis, hypercholesterolemia, hyperlipidemia, coronary heart disease, hypertension, and stroke [6,9,14]. As a result, additional intake from sources like omega-3-rich supplements or herbal remedies is recommended. Historically, plant-based treatments have been used as pharmacological therapies. Researchers have explored the use of purslane (Portulaca oleracea) leaves, which contain unsaturated fatty acids and antioxidants, including omega-3 fatty acids, vitamins A and C, and minerals such as magnesium and potassium, offering cardiovascular benefits. The researchers utilized purslane extract as an herbal tea blend, serving as a natural alternative to supplements in capsule form, which may be more expensive. In extract form, purslane leaves are hygienically processed and mixed with herbal tea, creating a convenient health drink for daily consumption. The purslane leaf extract was obtained through method maceration using 96% food-grade ethanol. Proximate tests were conducted to assess total energy, energy from fat, ash content, moisture content, carbohydrates (by difference), total fat, and protein content [5,24]. Sensory evaluation was conducted by semi-trained panelists to assess the color, aroma, and taste of herbal tea blends containing purslane leaf extract. This evaluation aimed to collect subjective feedback from potential consumers regarding the organoleptic characteristics of the product.

Penelitian ini bertujuan untuk mengetahui tingkat pemahaman konsep siswa SMA di Kabupaten Sorong pada pembelajaran kimia, besar miskonsepsi, serta faktor penyebab miskonsepsi. Metode yang digunakan dalam penelitian ini yaitu tes diagnostik disertai tingkat keyakinan jawaban (TKJ) yang disederhakan dari metode CRI. Hasil yang didapatkan dalam penelitian ini yaitu 13% siswa memahami konsep pada konsepsi yang diujikan, 63,06% siswa tidak memahami konsep, serta 23,94% siswa mengalami miskonsepsi. Miskonsepsi terjadi pada seluruh konsepsi yang diujikan, dengan persentase miskonsepsi terendah pada konsepsi partikel penyusun atom dan teori asam basa Bronsted-Lowry dengan besar persentasi 7,41%. Konsepsi dengan miskonsepsi terbesar yaitu pada partikel penyusun materi dengan angka persentase sebesar 48,15%. Faktor penyebab miskonsepsi sebesar 76,92% disebabkan oleh pemahaman siswa sendiri, sedangkan faktor penyebab oleh guru sebesar 15,38% dan buku referensi sebesar 7,69%. Berdasarkan hasil wawancara didapatkan data bahwa pembelajaran kimia yang diikuti oleh siswa di Kabupaten Sorong kurang menekankan pada penanaman konsep, akan tetapi lebih pada penyelesaian soal dan aplikatif lainnya, sehingga perlu untuk lebih menekankan lagi pada penanaman konsep. Konsepkonsep dalam kimia saling berkaitan satu dengan lainnya, sehingga jika tidak dipahami dengan baik akan mengganggu konsep lainnya
