Landslide control in the excavation of a shallowly buried tunnel with a large front slope
Authors: Ma H. , Qin W. , Zhang B. , Wang Z. , Qin W.
Published: May 2024

The tunnel with a large front slope is a common type of entrance in mountain tunnels. Excavation of this type of tunnel disrupts the original balance of the slope, which can easily lead to landslides or collapses. It is therefore important to choose suitable support for early reinforcement. This paper presents a case study of landslide control during the tunnelling of a shallowly buried tunnel with a large front slope. Three types of pre-support, including anti-slide pile, pipe roof and surface grouting, were used to control the landslide. In addition, a three-dimensional analysis was carried out to investigate the reinforcing effect of single and multiple pre-supports on the landslide and tunnel structure. The results showed that the deformation of the landslide and tunnel structure at the end of the entrance was the greatest, that is, the most dangerous, and the maximum slope displacement without pre-support was 15.1 cm. In tunnel structures, the arch area was the most prone to instability, while the bottom area did not experience significant deformation. The horizontal displacement control effect of the landslide body was ranked from strong to weak as surface grouting, pipe roof, and anti-slide pile, which is a decrease of 4.8%, 20.5% and 40.8% compared to the maximum displacement. While the vertical displacement control effect of the landslide was ranked from strong to weak as pipe roof, surface grouting, and anti-slide pile, which is a decrease of 4.3%, 45.1% and 63.7% compared to the maximum displacement. The reinforcement effect when three types of pre-supports were applied simultaneously was basically equal to the sum of the reinforcement effects when each pre-support was applied separately. This is mainly due to the different reinforcement mechanisms and areas of the three pre-supports, resulting in better overall effects.

Authors: Maulidya Azzah , Agus Suwignyo Rujito
Published: May 2024

A non-tidal swamp is an option to increase the rice harvested land and production, however, its utilization still depends on the natural condition so the plants are vulnerable to submergence and drought stress. Developing dual-tolerant varieties is the right choice for developing rice cultivation in non-tidal swamps. Inpara 8 has the SUB1 gene which is tolerant to submergence stress and Inpago 5 is tolerant to drought stress. The study aimed to evaluate the growth of BC1F2 from Inpara 8 and Inpago 5 that experienced submerged stress and its parents (Inpago 5 and Inpara 8). The research was carried out at the greenhouse of Agriculture Faculty, Sriwijaya University on July 2021 – January 2022. Inpago 5 has the highest average plant height ( 145.81 cm ), the highest number of tillers (4.73), the most productive tillers (3.87), and the highest total grain in the clump (720.87 grains), the weight of the clump grain (15.86 g) and the lowest percent of empty grain (33.47 %). The donor parent Inpara 8 had the highest average total grain per panicle (192.08), and the highest dry weight (20.69 g). BC1F2 Submerged had the highest average 1000 grain weight (25.26 g) and the fastest harvest age (114.50 DAP). The BC1F2 selfcross progeny which had experienced submergence stress and was not in the BC1F1 phase had almost the same characteristics as its two parents as indicated by the results of the observed parameters which generally did not show any significant differences.

Published: May 2024

Perubahan iklim membawa dampak pada hampir setiap bidang kehidupan. Pemerintah RI berkomitmen untuk meminimalisir dampak perubahan iklim ditunjukkan dengan diterbitkannya Perpres No. 98/2021 tentang Penyelenggaraan Nilai Ekonomi Karbon. Dalam Perpres tersebut, Pemerintah mengatur adanya skema perdagangan karbon melalui mekanisme carbon off set, pembayaran berbasis kinerja, dan pungutan atas karbon, serta kombinasi dari skema yang ada. Adanya Perpres ini di satu sisi merupakan wujud komitmen Pemerintah dalam mendukung upaya mengatasi perubahan iklim melalui sektor kehutanan, namun disisi lain Pemerintah seakan tidak tegas untuk menghentikan adanya pelanggaran-pelanggaran di bidang kehutanan, yang kemudian berimplikasi pada keadilan bagi masyarakat dan lingkungan sekitar. Ada dua isu yang dibahas dalam tulisan ini. Pertama, mengenai dinamika pengaturan carbon trading dalam konteks global dan nasional. kedua, mengenai perspektif keadilan dalam kebijakan carbon trading sebagai upaya mengatasi perubahan iklim.

Published: May 2024

PHA (polyhydroxyalkanoate) production by halophiles has attracted much attention in recent years. It was certified that the halophile bacteria Halomonas sp. PR-1 isolated from saltern soil synthesised poly (hydroxybutyrate-co-hydroxyvalerate) (PHBV) intracellularly from simple carbon substrate by means of FT-IR spectra analysis. The carbon and nitrogen source suitable for PHA production were selected as glucose and NH4Cl, respectively. The optimal ratio of glucose to NH4Cl was 20, when PHA content was 2.85 g/L and PHA yield was 50.85%. The optimal NaCl concentration for PHA biosynthesis was 30 g/L, when PHA yield was 63.3%. The halophile bacterium Halomonas sp. PR-1 was considered as a promising candidate for PHA production.
Research on the Motion Features Model for Underwater Targets with Multiple Highlights and Multiple Micro-Motion Forms
Authors: Sun Tongjing , Zhou Zihan , Peng Dongliang
Published: May 2024

Motion characterization, including Doppler and micro-Doppler, is crucial for the detection and identification of high-speed underwater targets. Under high-frequency and short-range conditions, underwater targets cannot be simply regarded as single highlight targets as they exhibit a complex structure with multiple scattering centers accompanied by distinct micro-motions. To address this multi-highlight and multi-micro-motion scenario, a model is proposed to characterize the motion features of underwater targets. Firstly, a mathematical model is established to represent the micro-Doppler features based on the single-highlight model. Subsequently, considering the overlap of multiple highlight echoes caused by the high-speed translation of the target and the long pulse detection signal, precise representation is achieved by setting motion positions and calculating time delays within the model. The results represent the echoes of moving targets with multiple highlights and micromotions. Finally, a time-frequency analysis method is employed to extract motion features and estimate target parameters, thereby validating the accuracy and effectiveness of the proposed model. This research provides a theoretical foundation for the modeling of underwater moving targets.

Authors: Stepien Robert , Wrzeciono Piotr
Published: May 2024

Air humidity significantly affects the sound of wooden instruments. The sound quality decreases when the instrument is exposed to low humidity for an extended period. Therefore, the instrument is treated with a humidifier to improve sound quality. This study aimed to verify the effectiveness of the humidification process by analyzing the quality of guitar sound with the methods used in signal complexity studies, such as Higuchi’s fractal dimension (HFD), symbolic analysis, and empirical mode decomposition (EMD). The sound quality was determined by the sound levels measured before, during, and after the guitars’ humidification. The methods used consistently confirmed the improvement of the guitar sound quality after the humidification process. Moreover, it was concluded that the sound quality changes irregularly during the humidification process.

Authors: Reginaldis Maria M , Supriyono Bambang , Setyowati Endah , Amin Fadilah
Published: May 2024

Introduction: The welfare of rural communities in developing countries such as Indonesia is a significant concern for the government. Therefore, the government's implementation of policies related to village fund allocation is expected to enhance the welfare of village communities. However, in practice, this policy has not yet brought about significant changes in the local communities, particularly in achieving village self-reliance.
 
Literature review: Policy implementation from the Triangle Model perspective is an approach developed by Walt & Gilson, (1994) which emphasizes four main stages in the policy process, namely agenda setting, formulation, implementation and evaluation. The agenda setting stage involves the selection of various problems faced by society to become the focus of decision makers. Next, in the formulation stage, legislative and decision-making bodies design and ratify policies. The implementation process is carried out by the government, followed by an evaluation stage that assesses the impact of the policy.
 
Method: This article aims to examine the process of implementing village fund allocation policies using the triangle analysis model (Buse et al., 2005) .The research informants comprised 23 individuals.
 
Result and Discussion: The results of this study indicate that the objectives of implementing village fund allocation in the Semangga district are known to the implementers/actors, as well as the benefits of village fund allocation being perceived by the village communities. However, the policy implementers lack effective communication to convince and educate the village communities. Additionally, there is a need to enhance human resource commitment and allocate additional funds to advance the villages towards self-reliance.
 
Conclusion: The findings of this study specifically demonstrate the real conditions in the research location regarding village fund allocation. This article presents opportunities for further research using the triangle analysis model in the implementation of village fund allocation policies.

Published: May 2024

Objective: The objective of this study is to investigate the relationship between corporate social responsibility and tax aggressiveness, with the aim of looking at the firmness of the relationship.
 
Theoretical Framework: This study aims to examine the strength and reliability of the connection between corporate social responsibility (CSR) and aggressive tax dodging actions through the utilization of a meta-analysis methodology.
 
Method: The quantitative method used is a meta-analysis approach of 61 studies and 228 observations.
 
Results and Discussion: The results of this study found a firm relationship between corporate social responsibility and tax aggressiveness. Through a meta-analysis, the results of the negative relationship between CSR and tax agressiveness were obtained. The next result was to confirm that the heterogeneity of previous research results related to CSR, and tax agresiveness was due to the diversity of CSR measurement strategies and characteristics of the state legal system.
 
Research Implications: This research has provided input into the fields of accounting and taxation by giving confidence in the relationship between aggressive tax behavior and the existence of disclosures of social responsibility
 
Originality/Value: This research is one of several studies using a meta-analysis approach. Different from other topics raised using this approach, in this research, the emphasis of the study is on the disclosure of CSR, which is correlated with the degree of the tendency of aggressive tax behavior or activities.  The study also uses moderators that have not been used in previous meta-analysis studies, namely state law characteristics.

Authors: Vieira Liliane , Costa Edgar
Published: May 2024

INTRODUCTION: Most children are exposed to screens and digital media early and for a longer period than recommended by scientific societies. This phenomenon has several harmful consequences for the health and development of children. Pediatric obesity has been highlighted as one of these effects, which may be related to exposure to screens as a sedentary behavior. OBJECTIVES: To search for and describe the evidence in the literature on the relationship between pediatric obesity and exposure to screens in childhood. METHODOLOGY: A non-systematic literature review was performed including articles published between 2018 and 2022 in the following databases: Cochrane, PubMed, Scielo and Lilacs. The terms “screen time” and “pediatric obesity” were used as descriptors. RESULTS: Associations were found between screen exposure time and increased waist circumference, body mass index (BMI) and childhood obesity stage. In addition, the use of screens mediated the positive relationship between obesity and the social status of the childrens neighborhood, as well as the relationship between obesity and asthma. CONCLUSION: Most of the evaluated studies demonstrated a positive association between the use of screens by children and the occurrence of obesity in pediatrics.

Authors: Josephine Esther , Wiranegara Hanny W. , Supriatna Yayat
Published: May 2024

The suburban areas of Jakarta have been chosen for the provision of subsidized housing to meet the needs of the Low-Income Community (MBR). The affordability level for MBR is a critical consideration in the provision of such housing. Suburban areas offer an advantage over inner-city areas due to relatively lower land prices. As a result, the development of housing for MBR has shifted to Jakarta's suburbs such as Bogor, Tangerang, and Bekasi Regencies. Previous research reviews have identified factors influencing MBR housing affordability, including housing location, housing accessibility, and travel behavior.
Aims: This study aims to identify factors influencing Housing MBR affordability in Jakarta's suburban areas, including Tangerang, Bekasi, and Bogor Regencies.
Methodology and results: Research variables include housing affordability, housing location, housing accessibility, and travel behavior. The research design uses a survey questionnaire method. The number of respondents from each regency is 40 MBR families residing in subsidized housing, randomly selected. The analysis technique used is multiple linear regression using Smart-PLS software. The study results show that the factors of housing location and travel behavior affect MBR housing affordability, while the accessibility factor does not.
Conclusion, significance and impact study: In suburban areas, to make housing affordable for MBR, it is necessary to provide easily accessible, integrated, and affordable public transportation infrastructure; provision of various facilities accessible by walking/cycling; and considering the density of MBR housing to attract various parties to provide facilities.

Scale Effects in Wind Tunnel Testing: Extrapolation of the Drag Coefficient
Authors: Traub Lance W.
Published: May 2024

Subscale wind tunnel data extrapolation is both a necessary and challenging undertaking. Most readily available wind tunnel facilities can achieve Reynolds numbers that are typically an order of magnitude lower than those of the full-scale flight article. Consequently, the wind tunnel data need to be scaled, with the Reynolds number disparity impacting force and moment measurements. Although computational fluid dynamics is ascending as a valuable tool for enabling scaling, the most common extrapolation methodologies are analytic and semi-empirical in nature. Consequently, a new approach is presented to scale both the minimum drag coefficient and the sectional pressure drag coefficient that uses the subscale data to define extrapolation exponents. Implementation requires a minimum of two subscale tests to enable specification of the exponents determined through coalescence of the extrapolated subscale tests. The approach is simple to implement and can be applied to both airfoils and wings. Numerous cases are presented for method validation.
Laughing when the Lights Go Out: Humour and the Electricity Crisis in South Africa
Authors: Hurst Andrea , Donian Jennalee
Published: May 2024

As a dire consequence of complex problems, the centralised, state-owned power utility in South Africa, Eskom, has implemented so-called “loadshedding.” This is the name for a regime of scheduled power-cuts that has persisted since 2007, causing significant economic and psychological damage among South Africans. Nevertheless, despite the severity of the Eskom debacle, South Africans have produced an unending stream of social media humour in response to it. In this article, we ask what such humour might tell us about the nature of the collective South African psycho-social mindset. We collected 380 humorous items relating to the portrayal of Eskom in South African popular culture. These took the form of comic strips, comical memes, and satirical reels from various social media platforms, including Facebook, Instagram, TikTok, WhatsApp, Twitter, and YouTube. The humorous responses, primarily in English as South Africa’s lingua franca, were produced by a range of content creators—from celebrities like Trevor Noah and other regular content creators to unknown beneficiaries of virality—representing a diversity of cultures, humour styles, contexts and audiences. We created a comprehensive list of all the humorous items that readily lent themselves to interpretive analysis in terms of an anthropomorphic portrayal of Eskom as the abuser in an ongoing abusive relationship with the South African citizenry suffering from a victim mentality. The main aim of the article is to demonstrate the pervasiveness of this portrayal, the significance of which lies in its capacity to open up avenues for further philosophical reflection and sociological research.
Many children, many blessings: Reinterpreting Psalm 127:5 in the Nigerian context
Authors: Ademiluka Solomon Olusola
Published: May 2024

The idea of “many children, many blessings” in Ps 127:5 resonates with African traditional belief systems. However, in contemporary Nigeria, modernisation has introduced inescapable variables that make large families undesirable. In spite of this, many Nigerians still produce many children, apparently relying on the traditional belief that God determines one’s number of children, and possibly also on Ps 127:5. Applying the historical-critical and descriptive methods, the article assessed the relevance of Ps 127:5 in contemporary Nigeria and found that the text reflects the ancient Israelite context wherein parents depended on the number of their children in socio-economic terms, a situation which also resonates with the premodern African context. The modern Nigerian context, however, brought about changes in the pattern of parent-child interdependence such that now even peasant parents have to send their children to school and do all the manual work alone. In view of the high rate of unemployment, even many university graduates still have to depend on their parents. With this transition, large families come with implications such as hunger, poor health, and inadequate or lack of Western education for the children. Moreover, raising large families now has to contend with global issues such as overpopulation and family planning. To this end, a pastoral application of Ps 127:5 in Nigeria now has to respond to issues that come with large families.
A Comparison of Loneliness and Social Support among South African Older Persons during a Pandemic
Authors: Geyer Stephan , Teater Barbra
Published: May 2024

Pandemics, such as the outbreak of the novel coronavirus (Covid-19) in March 2020, have a negative impact on older persons’ (60 years and older) physical and mental health. Research on the effects of Covid-19 on older persons’ experience of loneliness and self-reported social support has predominately originated from the Global North. Applying the strengths perspective, the present study aimed to determine and compare the loneliness and social support among South African older persons during a pandemic. A cross-sectional survey was operationalised to collect data from community-dwelling older persons (n = 139) and older persons residing in residential care facilities (n = 99) through purposive sampling across five South African provinces. A loneliness scale was used to measure the respondents’ overall loneliness, including emotional and social loneliness. A social support scale was used to measure the availability of social support across four domains. The survey focused on social contact, number of close friends/relatives, socio-demographics, and subjective physical and mental health, respectively. Independent samples t-tests were run to explore any statistically significant differences between the two groups. Community-dwelling older persons were found to present with marginally higher levels of loneliness. No statistically significant differences were identified between the two groups. Community-dwelling older persons measured higher on social support than their peers in residential care. Two domains of social support, namely, affectionate support and positive social interaction, were found to be significantly different (p < 0.01). Based on the study’s results, implications for strengths-based gerontological social work services in resource-constrained settings during a pandemic were delineated.

Revisão bibliográfica: A crescente resistência antimicrobiana é um desafio global em saúde pública que está associada a um alto número de mortes anuais e ameaça superar o câncer como a principal causa de mortalidade até 2050. Ainda, o desenvolvimento de novos antimicrobianos enfrenta obstáculos significativos incluindo o alto custo, incerteza de mercado e falta de interesse da indústria farmacêutica. Buscando atenuar esse cenário, novas alternativas antimicrobianas estão sendo desenvolvidas e demonstram resultados promissores. A terapia fágica utiliza bacteriófagos para infectar bactérias, os peptídeos antimicrobianos são moléculas de aminoácidos com ação direta ou imunomoduladora, e os compostos organometâlicos são redes de coordenação de metais e ligantes orgânicos com propriedades antimicrobianas. Considerações finais: Cada uma das alternativas descritas no apresenta vantagens e desafios, mas todas oferecem esperança no desenvolvimento de novos antimicrobianos eficazes. A resistência antimicrobiana representa uma ameaça à saúde pública global e exige a busca por soluções inovadoras para garantir o sucesso contínuo da medicina moderna.

Objetivo: analisar estudos realizados sobre o uso de aromaterapia como prática não farmacológica para manejo da dor em crianças. Métodos: trata-se de uma revisão integrativa  acerca do assunto relacionado ao uso da aromaterapia no setor pediátrico. Foram realizadas buscas nos periódicos SciELO, PubMed e Medline de artigos publicados entre o ano de 2013 e 2023. Resultados: a partir da pesquisa nas bases de dados estabelecidas, foram identificados 395 estudos. Os títulos e resumos dos mesmos foram lidos, seguindo os critérios de inclusão e exclusão, resultando na exclusão de 342 artigos que não abordaram a aromaterapia na pediatria na primeira análise. Na segunda análise, procedeu-se à exclusão de outros nove artigos, resultando em nove artigos incluídos na pesquisa. Considerações Finais: a aromaterapia, especialmente com óleo de lavanda, pode ser uma opção promissora e complementar no manejo da dor e no aumento do bem-estar em diversos cenários clínicos, embora seja importante considerar a individualidade de cada paciente e contexto ao aplicar essa abordagem terapêutica.

Published: May 2024

Objetivo: Identificar ferramentas de enfrentamento ao ageísmo desenvolvidas por meio das relações intergeracionais frente à transição demográfica. Métodos: Trata-se de revisão integrativa em que foram selecionados 21 artigos na Web of science, Pubmed, Embase, Portal Capes e Scopus. Resultados: Observou-se que quanto maior o contato com a população idosa e mais conhecimento sobre o envelhecimento, seja no meio educacional, familiar, ou dos profissionais cuidadores, menos estereótipos negativos são vistos em relação às pessoas mais velhas. A promoção de relações intergeracionais no ambiente familiar e no mercado de trabalho foi outra importante ferramenta no combate ao idadismo, especialmente no contexto da pandemia da COVID-19. Os efeitos positivos da autopercepção do envelhecimento foram observados em pessoas que vivem em regiões com envelhecimento populacional lento. Considerações finais:  Quanto maior o conhecimento sobre o processo de envelhecimento e contato com pessoas idosas, mais atitudes e visões positivas em relação a esse grupo foram agregadas enquanto ferramentas de enfrentamento ao idadismo em vários espaços sociais. Como limitação do estudo, destaca-se a escassez de publicações sobre as relações intergeracionais e seu impacto na redução do ageísmo após a pandemia da COVID-19.

Copper Catalyzed sp3 C-H Alkenylation
Authors: Chen Ting-An , Staples Richard , Warren Timothy
Published: May 2024

The prenyl group is present in numerous biologically active small molecule drugs and natural products. We introduce benzylic C-H alkenylation of substrates Ar-CH3 with alkenylboronic esters (CH2)3O2B-CH=CMe2 as a pathway to form prenyl functionalized arenes Ar-CH2CH=CMe2. Mechanistic studies of this radical relay catalytic protocol reveal diverse reactivity pathways exhibited by the copper(II) vinyl intermediate [CuII]-CH=CMe2 that involve radical capture, bimolecular C-C bond formation, and hydrogen atom transfer (HAT).
The pseudo-ternary phases Eu0.28Yb0.72MnPt and YbCd0.13Mn0.87Pt as TiNiSi type derivatives of the elusive or non-existent “YbMnPt”
Authors: Ponou Simeon , Mudring Anja-Verena , Friedrich Benedikt
Published: May 2024

The ternary RE-Mn-Pt systems (RE = rare-earth metal) have remained surprisingly vacant. Our attempts to stabilize hypo-thetical equiatomic “REMnPt” phases that are isovalent to RECdPt were found to be extremely challenging. However, using metal fluxes synthesis approaches, two quasi-ternary phases Eu0.28Yb0.72MnPt and YbCd0.13Mn0.87Pt, with stoichiometries in the vicinity of the elusive “YbMnPt” phase, were obtained by reacting mixtures of the elements at high temperature with large excess of Eu and Cd, respectively. The two title compounds crystallize in the orthorhombic TiNiSi type structure (space group, Pnma), according to single crystal X-ray diffraction data, with Eu/Yb or Cd/Mn atomic mixing at the corresponding atomic sites. Noteworthy, the two phases feature Mn (3d5) linear zigzag chains with very similar Mn–Mn distances of 2.97 Å, longer than the sum of Mn covalent radii (2.74 Å), but non-negligeable. The Mn chains also interact strongly with the surrounding Pt atoms to form the polyanionic {MnPt} framework. The rare-earth metals Yb and Eu are arguably divalent and, we could surmise that the apparent non-existence of the pristine “YbMnPt” phase can be ascribed to geometric frustrations as they can result from packing mismatched between the cationic and anionic sublat-tices. Hence, partial isovalent substitutions at either Yb position by larger Eu atom or at Mn position by larger Cd atom may be necessarily to optimize the atomic packing. Our findings further demonstrate that chemical heterogeneity can be vital for the stability of certain classes of elusive materials in general.
De Novo Synthesis and Structural Elucidation of CDR-H3 Loop Mimics
Authors: Roche Stephane , Zhao Guangkuan , Richaud Alexis , Williamson Thomas , Feig Michael
Published: May 2024

The binding affinity of antibodies to specific antigens stems from a remarkably broad repertoire of hypervariable loops known as complementarity-determining regions (CDRs). While recognizing the pivotal role of the heavy-chain 3 CDRs (CDR-H3s) in maximizing antibody-antigen affinity and specificity, the key structural determinants responsible for their adaptability to diverse loop sequences, lengths, and non-canonical structures are hitherto unknown. To address this question, we achieved a de novo synthesis of bulged CDR-H3 mimics excised from their full antibody context. CD and NMR data revealed that these stable standalone -hairpin scaffolds are well-folded and retain many of the native bulge CDR-H3 features in water. In particular, the tryptophan residue highly conserved across CDR-H3 sequences was found to extend the kinked base of these -bulges through a combination of stabilizing intramolecular hydrogen bond and CH/ interaction. The structural ensemble consistent with our NMR observations exposed the dynamic nature of residues at the base of the loop, suggesting that -bulges act as molecular hinges connecting the rigid stem to the more flexible loops of CDR-H3s. We anticipate that this deeper structural understanding of CDR-H3s will lay the foundation to inform the design of antibody drugs broadly and engineer novel CDR-H3 peptide scaffolds as therapeutics.
Hacer visible: la contribución de la arquitectura forense para la lectura de los eventos contemporáneos y la experiencia latinoamericana
Authors: Wisnik Guilherme , Marujo Paula
Published: May 2024

Este artículo busca analizar la actuación de la agencia Forensic Architecture y comprender cómo la arquitectura puede ser una herramienta importante para la lectura de los eventos contemporáneos, y cómo esta práctica se inserta en el territorio latinoamericano. Para lograrlo, se presenta el marco teórico desde el cual el grupo se forma, respaldado por la tesis del nevoeiro (‘niebla’) de Guilherme Wisnik y la cuestión de la verdad, la imagen y la vigilancia en la contemporaneidad. A través de un análisis teórico y estudio de casos, se busca definir la arquitectura forense como una metodología capaz de navegar a través de la niebla contemporánea y tener una acción efectiva mediante la creación de una nueva epistemología que conecta diversas áreas de conocimiento para combatir la violencia de Estado. Finalmente, se examinan los nuevos lenguajes de la arquitectura forense en América Latina, con la apertura de nuevas agencias que sitúan la práctica desde otras necesidades y perspectivas.
Fenomenología e inteligencia artificial: una perspectiva líquida a la arquitectura del siglo XXI
Authors: Fraile-Narváez Marcelo
Published: May 2024

En los últimos años, los avances en Inteligencia Artificial (IA) han transformado la interacción con el mundo y están dando forma a la industria arquitectónica. Este artículo explora la importancia de la IA en el diseño arquitectónico, desde donde se destaca su potencial para conectar lo digital con lo sensorial en el diseño contemporáneo. A partir de un estudio de caso, y tomando como referencia el texto de Marcos Novak, Arquitectura líquida (1991), se exploran los conceptos de realidad virtual y paisajes inmersivos tridimensionales como ejes para clasificar y estudiar el impacto de la IA en la arquitectura, como una tecnología que abre nuevas perspectivas para rescatar la subjetividad como condición esencial para acceder a los saberes generados por los nuevos tiempos. Se concluye que este trabajo es un punto de partida para futuras investigaciones que promuevan la discusión y la ampliación de este tema en evolución.
