Introduction: Steel-concrete composite girders have been widely used in bridges, with the stability of the interface being crucial. Shear connectors and reinforced concrete slabs play a key role as interfaces. Understanding the interaction between the composite beam and slab is essential for predicting the overall system response. It is necessary to optimize the connection between steel beams and reinforced concrete slabs in steel-concrete composite girders and facilitate their assembly and installation on-site, emphasizing their pivotal role in upholding the structural integrity of composite systems. The purpose of the study was to conduct an experimental investigation and a numerical simulation using the finite element method. During the study, the following methods were used: examining the behavior of IPE and IPN perforated shear connectors using push-out tests. The main objective was to analyze how the I-shaped perforated connector, concrete slab, steel beam, and rebar affect the measured slip between the steel beam and concrete slab. To achieve that, specimens with IPE80 or IPN80 shear connectors having circular or long cut holes containing 8 mm or 6 mm diameter steel bars were used to enhance the connector’s resistance against uplift forces. The test setup follows Eurocode 4 guidelines, focusing on hole shape and anti-lift rebar diameter parameters. The predominant failure modes were mainly dictated by the crushing of the concrete slab. As a result, it was found that the hole geometry of IPE and IPN perforated shear connectors significantly impacts shear load capacity and ductility. The long cut hole shape in IPE and IPN perforated shear connectors exhibits superior ultimate load capacity but less interfacial slip compared to the circular hole. The IPE and IPN perforated shear connectors demonstrated satisfactory ductility for all tested hole shapes, and the 3D finite element models are consistent with the test results.

Published: October 2024

The research aims to provide a comprehensive analysis of the obligation to provide dowry in marriage at the time of the marriage contract from a juridical, sociological, and philosophical perspective. This research is normative legal research (Doctrinal Research) with an interdisciplinary approach. The results of the research state that legally dowry is not a pillar of marriage, therefore negligence in its implementation does not cause the marriage to be annulled and valid, however, the dowry must still be given by the prospective husband to the prospective wife either in full or in part in cash or postpone it. Sociologically, because the law is always dynamic, the application of dowry is adjusted to local community habits. The essence is that dowry does not burden men and also does not degrade women. Philosophically, giving a dowry is not just at a transactional and materialistic level, but a dowry is essentially a form of seriousness and love as well as the groom's appreciation for the bride he will marry. Therefore, women must accept the dowry happily as a respect for their dignity and not interpreted as a buying and selling transaction against themselves.

INTERNALIZING INCLUSIVE ISLAMIC VALUES AT MUSLIM OI BURA: A COUNSELING CONCEPTUAL
Authors: Atiyah Kanzul , Sa'adah Nurus
Published: October 2024

Islam openly accepts differences in human beliefs on this earth. According to Islam, diversity is considered a necessity, so differences in beliefs are also normal. However, the social reality that occurs is that there are still practices of religious discrimination in society, such as the case of religious discrimination carried out by a group of Muslims in Tambora against local Hindus. This article aims to develop the concept of counseling as an effort to handle problems. The research method used is a literature study with data collection techniques from books and journal articles. This research produces the concept of a counseling group approach using the REBT technique as an alternative to eliminating negative prejudices that hinder the birth of tolerance. The REBT technique used also adopts Islamic values. This step aims to suppress irrational beliefs by refreshing the meaning of inclusive Islam. In the process, it is hoped that it will be able to support the formation of an attitude of tolerance in the Muslim community in Tambora.

Published: October 2024

Housing and the urban are two dimensions of contemporary life that are linked to the type of development desired at the municipal level. The problem with settlements in the State of Mexico is that their approval is the result of local and state decisions. In this work these issues are analyzed in the context of metropolitan areas. The objective of the work is to understand in a better way the authorization of the urban complex “Hacienda San Javier”, located in Texcoco de Mora, in the State of Mexico, where the dimensions of housing and the urban impact the municipal territory and the region; Well, although they offer alternatives for the middle class in planned housing - with permits and authorizations prior to their construction; works that generate employment, greater investment locally and improve consumption, and that help the productive chains of the economy—; They also modify ecosystems, change land use and generate a new urban-environmental-territorial ordering. The methodology used expresses deductive knowledge supported by official documents and case studies that analyze a locality; and at the same time they resort to quantitative methods to generate research that relates information and facts. The study is also complemented by conducting interviews in the “Alameda Municipal”, which enriches the qualitative research. The results indicate which agencies authorize these projects; and with data from the National Institute of Statistics and Geography (INEGI), we know the condition of housing in Texcoco and the effect of this type of development (which contrasts with unplanned or irregular housing); Furthermore, the importance of the management of public services and their social, economic and environmental relationship that high-impact subdivisions entail in the municipal order is highlighted.
Decentralized sanitation alternatives in cities of the global south—A case of constructed wetlands in Bulawayo, Zimbabwe
Authors: Muzioreva Happison , Gumbo Trynos
Published: October 2024

Constructed wetlands have emerged as a sustainable alternative for decentralized wastewater treatment in developing countries which face challenges with urbanization and deteriorating infrastructure. This paper discusses the key factors affecting the implementation of constructed wetlands in developing countries. A case study research design was adopted, which focused on Bulawayo, Zimbabwe. A mixed-method approach was adopted for the study. Spatial analysis was conducted to identify potential sites for constructed wetlands in the city of Bulawayo. Semi structured interviews were conducted, with relevant stakeholders, such as town planners, civil engineers, NGO representatives, community leaders, and quantity surveyors. The findings reveal that political reforms, public acceptance, land availability, and funding are crucial for the successful implementation of constructed wetlands. Additionally, four sites were identified as the most favorable preliminary locations for these systems. The paper captures all the key factors relevant to the implementation of constructed wetlands (CWs) with a closer look at policy and the role it plays in the adoption of decentralized wastewater treatment systems. Formulating policy around the decentralized sanitation systems was considered imperative to the success of the systems whether in implementation or in operation. The paper adds to knowledge in the subject of sustainable wastewater treatment alternatives for developing countries. However, further research can be conducted with a different methodology to ascertain the applicability of the systems in developing urban cities considering other important aspects in the implementation of wastewater treatment systems.
Can the European nuclear power industry compete with the Chinese nuclear power industry?
Authors: Rothwell Geoffrey
Published: October 2024

European commissioner for the Internal Market, Thierry Breton, told Le Journal du Dimanche in January 2022, “Existing nuclear plants alone will need 50 billion euros of investment from now until 2030. And new generation ones will need 500 billion”. This paper considers whether these values are realistic. Further, it asks whether these investments would yield an internationally competitive European nuclear power infrastructure given that the nuclear power industries in the Organization for Economic Cooperation and Development member countries have lost global nuclear market share to Russian and Chinese firms since 1995.The paper investigates whether the European nuclear industry even with massive investment can compete with the Chinese nuclear industries. It concludes that the European (in particular, the French) nuclear power industry will be unlikely to be cost competitive with the Chinese nuclear power industry unless financing and new plant orders are immediately forthcoming. To achieve carbon neutrality, the issue becomes whether European Union countries can afford indigenous nuclear technologies or will need to import nuclear power plants from Asia.

Authors: Xia Aimin , Girum Tanasorn
Published: October 2024

This study explores the transformative role of art design interventions in the sustainable development and infrastructure enhancement of intangible cultural heritage, with a particular focus on honored brands. The research develops a framework that positions aesthetic and interactive art design interventions as pivotal components in revitalizing these brands. Aesthetic interventions translate the brand’s core philosophy, spirit, and values into compelling visual symbols, harmonizing cultural heritage with modern image design to elevate brand reputation and consumer preference. Interactive interventions enhance user experience, particularly among younger demographics, by integrating technological and entertainment-based engagement, thereby strengthening consumer loyalty and brand influence. The study further investigates how these art design interventions serve as catalysts for broader social development, contributing to the modern relevance and societal impact of time-honored brands. Additionally, it examines the impact of these interventions on sustainable development, societal support, and policy alignment. By weaving together these elements, the research underscores the critical importance of aligning brand strategies with societal goals, fostering environments where brands actively contribute to social welfare and sustainable growth. The findings offer valuable theoretical insights and practical strategies for the sustainable development of time-honored brands, providing clear directions for future research and practice.

Published: October 2024

Walking, a physical activity beneficial for both physical and mental health, is influenced by various factors. Although previous studies have acknowledged that walking behavior is influenced by environmental and psychosocial factors, little is known about their interactions. Based on a socio-ecological model and focusing on Chinese college students, the purpose of this study was to examine the influence of campus walkability and psychosocial factors on college students’ walking behavior, including the interactions between these factors. This study seeks to enhance understanding of how to promote walking behavior through campus environmental design and psychological interventions. Multiple regression analysis was conducted on the questionnaire data. Findings revealed that campus walkability significantly influenced both walking behaviors, alongside psychosocial factors such as attitude, self-efficacy, perceived benefits, perceived barriers, and subject norms. Additionally, significant differences in interaction effects between these factors were observed for purposeful versus recreational walking behaviors. These interactions suggest that campus walkability more substantially promotes walking behavior in students with negative psychosocial factors, whereas its impact is less pronounced in those with positive psychosocial factors. The results underscore the need to focus not only on developing walkable environments but also on understanding the synergies with the psychosocial factors of target populations, offering crucial insights for campus planning and health promotion practices.

Published: October 2024

O desenvolvimento do agronegócio brasileiro tem sido cada vez mais pautado no uso de microrganismos na agricultura. Com a crescente demanda por produtos biológicos, muitos agricultores passaram a multiplicar bactérias e fungos em suas propriedades em biofábricas, em um sistema conhecido como on farm. Entretanto, essas instalações são comumente desprovidas de qualquer controle sanitário e isso resulta em baixíssima multiplicação do microrganismo alvo e predominância de contaminantes. Nesse contexto, o objetivo do presente trabalho foi analisar a qualidade de produtos multiplicados a partir de produtos à base de Bacillus e Trichoderma na região de Curitibanos – SC. As análises compreenderam aspectos de pH, coloração e quantificação de microrganismos multiplicados, tanto os provenientes do produto original como os contaminantes, com base em características morfológicas das colônias. A maior parte das amostras não apresentava o microrganismo que os produtores desejavam propagar, e todas as amostras analisadas apresentavam microrganismos contaminantes. Os dados revelam que a multiplicação a partir das biofábricas não foi eficiente para gerar bioinsumos com qualidade e concentração adequada. Esses microrganismos multiplicados, se utilizados em áreas agrícolas, contaminarão o solo, plantas e, possivelmente, recursos hídricos, e representam um considerável risco para a saúde ambiental, bem como humana.

Authors: Giménez-Salinas Framis Andrea , Gómez Lanz Javier , Ruiz Arias Sergio
Published: October 2024

El estudio tiene como objetivo comparar las características sociodemográficas, así como los factores de riesgo en la infancia y en la edad adulta entre dos muestras de delincuentes: un grupo de personas condenadas por delitos económicos (n=349) y otro de personas condenadas por delitos comunes (n= 328). Se encontraron diferencias significativas en la mayoría de las variables examinadas: los delincuentes económicos tienen mayor edad, son nacionales en mayor medida, tienen mayor nivel educativo, muestran más estabilidad en el empleo y la familia y poseen menos factores de riesgo en la infancia. Las diferencias en la edad adulta se acentúan entre los dos grupos en referencia a los factores de riesgo asociados a la delincuencia común (abuso de sustancias, violencia de género), pero, en cambio, se reconocen menos diferencias en las crisis económicas o personales vividas en la edad adulta. Las diferencias encontradas están en la línea de estudios similares desarrollados en otros contextos culturales.
La ley de la concentración aplicada al estudio espacial y temporal del delito
Authors: Summers Lucía
Published: October 2024

La ley de la concentración, o principio de Pareto, afirma que el 80% de las consecuencias provienen del 20% de las causas. Aplicado al delito, la ley mantiene que éste no se distribuye de forma aleatoria o uniforme según el espacio o el tiempo, sino que la mayoría del delito ocurre en los lugares y franjas temporales más criminógenos, ajustándose a unas proporciones del 80/20. Este artículo presenta esta ley e ilustra su aplicación utilizando análisis originales y de otros estudios, explicándose la metodología para crearcurvas cumulativas y de Lorenz, y para medir el nivel de concentración utilizando el coeficiente de Gini. Se discuten también las implicaciones de la ley de la concentración para la prevención del delito.
Ecate in Dacia tra latitanza e assimilazione
Authors: Casella Valentina
Published: October 2024

Ancora oggi permangono dubbi e perplessità sull’origine di Ecate e del suo culto; si tratta di una divinità particolarissima che possiede attributi tipici di ambiti che vanno da quello lunare e ctonio a quello magico. Il suo culto, ben attestato nel bacino orientale del Mediterraneo, non sembra aver riscosso la stessa fortuna nelle zone occidentali dell’impero romano. Questo contributo si propone di indagare l’ambigua vicenda della diffusione del culto di questa divinità in Dacia e di verificare, all’interno del più ampio contesto relativo all’affermazione delle divinità orientali nella provincia, quanto l’identità religiosa e sociale del territorio abbia opposto resistenza alla venerazione di Ecate e quanto abbia invece assimilato alcune sue peculiarità sintetizzandole, magari, in altre entità divine di più ampia diffusione.

Let $\mathbb{F}_{q}$ be a finite field of characteristic $p>0$ with $|\mathbb{F}_{q}|=q=p^{k}$ and $\mathcal{U}(\mathbb{F}_{q}G)$ be the unit group of the group algebra $\mathbb{F}_{q}G$ for some group $G$. There are $6$ groups of order $42$ up to isomorphism. In this paper, we provide a characterization of $\mathcal{U}(\mathbb{F}_{3^{k}}(C_{3}\times D_{2n}))$ and establish the structures of the unit groups of some finite group algebras of groups of order $42$.
A Real-Time Key-Finding Algorithm Based on the Signature of Fifths
Authors: Kania Paulina , Kania Dariusz , Łukaszewicz Tomasz
Published: October 2024

The signature of fifths is a special kind of music representation technique enabling acquisition of musical knowledge. The technique is based on geometrical relationships existing between twelve polar vectors inscribed in the circle of fifths, which represent individual pitch-classes detected in a given composition. In this paper we introduce a real-time key-detection algorithm which utilizes the concept of the signature of fifths. We explain how to create the signature of fifths and how to derive its descriptors required by the algorithm, i.e., the main directed axis of the signature of fifths, the major/minor mode axis, the characteristic vector of the signature of fifths, the characteristic angle of the signature of fifths, and the angle of the major/minor mode. We performed a series of experiments to test the algorithm’s effectiveness. The results were compared with those obtained using key-detection approaches based on key-profiles. All experiments were conducted using works composed by J.S. Bach, F. Chopin, and D. Shostakovich. The distinctive features of the presented algorithm, with respect to the considered key-detection approaches, are computational simplicity and stability of the decision-making process.

Published: October 2024

Autonomous driving is currently a hot topic in automotive engineering. Accurately predicting the future trajectory of self-driving cars can significantly reduce the occurrence of traffic accidents. However, predicting the future trajectories of vehicles is a challenging task since it is influenced by the interaction behaviors of neighboring vehicles. This paper proposes a framework that allows for parameter sharing and cross-layer independence, based on a dynamic graph convolutional spatiotemporal network, to study the interactions between vehicles and the temporal dynamics in historical trajectories. By extracting dynamic adjacency matrices from different vehicle interaction features, the model can describe dynamic spatiotemporal relationships, enabling it to handle changes in traffic scenarios. Finally, the proposed model was experimentally compared with existing mainstream trajectory prediction methods using the NGSIM dataset. The results demonstrated that our trajectory prediction model achieved excellent performance in terms of model parameters and prediction accuracy. Compared to the four mainstream models, our model improved accuracy by 35.73%. In addition, we also analyze the relationship between model complexity and efficiency.

The service was carried out in Weuraya Village and Lampaya Village, Lhoknga District, Aceh Besar Regency with the target of fish farmer business groups. At first, the need for fish in Lhoknga and its surroundings only relied on fishing at sea by fishermen. Over time, the need for fish and employment for the community here eventually led to fish farming. Seeing the potential of fish farming that is getting better in this area, a group of people in this area took the initiative to form a fish farming business group located in Lampaya and Weuraya Villages, Lhoknga District, Aceh Besar. These two villages are located not far from the center of the Banda Aceh city market, estimated at about 25 km from the location of the farm which can be reached for approximately 1 hour drive. Determining the composition of fish feed ingredients is an important issue because not all compositions will provide the best results for fish growth. The high price of fish feed in the market with low protein content causes fish farmers to experience difficulties in cultivating fish. The objectives of this activity are first, to concoct their own animal feed from tofu dregs, snails or rice snails, wheat flour, rice bran, and coconut meal which are very widely available around Lhoknga. The second training was for the Lampaya and Weuraya fish farmer groups in Lhoknga sub-district to make fish feed. All members of the Lampaya and Weuraya fish farmer groups are involved in the two scopes of work above, so that these two groups will have the knowledge and skills to make quality and healthy fish feed for fish. From the results of the monitoring of the service team, it is clear that the high enthusiasm of the community can be measured by the crowd of socialization and training participants, as well as the many questions that arise during the practice of making fish pellets. At the end of the activity, the community has mastered how to make their own fish feed and can save 60% of the total cost

The participants were lectured about ecoenzyme and its benefits and followed by discussion. It was then followed by a practical session on ecoenzymen-making activity. From this activity, the PKK group in Gampong Kopelma Darussalam, Banda Aceh, gained knowledge about a method to manage household organic waste become useful products. Furthermore, these skills can also be a source of additional income for local residents. During the training, the service team brought ready-made ecoenzymes and plants so they could provide examples of how to apply ecoenzymes to plants. The ecoenzyme and plants were given as souvenirs to the training participants.

This article reports on the design and implementation of thematic extracurricular activities for primary school students regarding the introduction of two professions :  architect and urban planner. The program was carried out during the pandemic with all the limitations for direct physical interaction. This report elaborated methods for combining materials and ways to manage interactions in such situation. The combination of materials is expected to provide an introduction to the professions and introduce knowledge about the field in an interesting and age-appropriate way for children. It also act as a proxy to reach parents and schools with architectural design and urban planning issues. Implementation that combines offline and online methods is an alternative model for implementing other activities both during the pandemic and in normal situations. The results of the activity show that students and parents were very interested and actively involved. The main obstacle faced and worth anticipating in implementing similar activities is the level of  familiarity with online interactions (with was new at the time) and finding mechanisms for activities to develop scientific interests at an early age, not incidentally but on a regular basis.

The problem of household waste is often found around settlements, such as what happened in Beringin and Lueng Gajah Hamlet, Gampong Kayee Lee, Want Jaya District, Aceh Besar Regency. Household waste piling up on the side of the road, being burned, blocking drainage and causing a foul smell, is a common occurrence. This occurs due to a lack of public awareness and knowledge in managing waste, which results in people not caring about their waste. On the other hand, there is no waste management system managed by the local government. This is proven by the absence of waste facilities and infrastructure provided by the gampong. If this continues, this condition will pollute the environment and cause odor pollution that will damage the environment. Therefore, this Community Service activity aims to maintain the environment of Gampong Kayee Lee so that it is free from waste and becomes an independent village in waste management. Real action is taken by reducing waste generation, as well as increasing the income of partner communities through waste management. Partner 1 is the Beringin Hamlet Community Group (Pokmas) and Partner 2 is the Lueng Gajah Hamlet Pokmas. The activities carried out are building a WCP system Waste Bank and coordinating with DLH, implementing a savings book system for depositing waste that can be cashed in, making handicrafts from inorganic waste for sale. Organic vegetables are also planted and sold in their neighborhood shops. Implementing this system will reduce waste generation and increase income.

ABSTRACT
 
Determination of biothermoplastic composite formulation is essential to produce the best biothermoplastic composite characteristics and meet the standards. This study seeks to identify the characteristics of the best biothermoplastic composites in variations of thermoplastic starch formulations, thermoplastic glucomannan and polylactic acid. This study used a Completely Randomized Design (CRD) with 5 treatments of TPS/TPG formulas with PLA, namely 90:10, 80:20, 70:30, 60:40, 50:50. There were 4 repetitions of each treatment, for a total of 20 experimental units. The variables observed were tensile strength, elasticity, elongation at break, melting point, biodegradation, swelling and density. The diversity analysis showed that the formulation of thermoplastic starch-thermoplastic glucomannan and polylactic acid had a very significant effect on the tensile strength, elasticity, elongation at break, melting point, biodegradation, swelling and density of biothermoplastic composites. Biothermoplastic composites with the formulation of TPS/TPG: PLA = 50:50 produced the best characteristics with a tensile strength of 26.71 MPa, elasticity of 932.04 MPa, elongation at break of 2.89%, biodegradation of 15.25 days, melting point of 152.65oC, density of 1.26 g/cm3 and swelling of 1.32%.
