Published: December 2024

Purpose: This research was planned as correlational and cross-sectional to examine the relationship between earthquake risk perception and claustrophobia and the affecting factors.
Method: This correlational cross-sectional study was conducted to identify the relationship between earthquake risk perception and claustrophobia level in earthquake victims who experienced the Elazığ earthquake on January 24, 2020, and the affecting factors. The population of the research is individuals who experienced the earthquake in Elazığ city. The sample group of the research consisted of 400 people who agreed to participate in the research and were over the age of 18. In this study, data were collected via online survey method between 01.07.2023 and 01.09.2023. Data were collected using an information form on socio-demographic characteristics and a questionnaire prepared by the researchers by scanning the relevant literature.
Results: It was identified that the average age of the study participants was 35.08±12.51, half of them were women (54.8%) and 55% had children. According to the T-Test analyses in this research; it was found that there are significant differences between women's and men's perception of earthquake risk. According to the Anova Test analyses in this research; it was observed that as the education level of earthquake victims increased, the severity of claustrophobia decreased and as the level of damage in their homes increased, the severity of claustrophobia increased. It was identified that there was a positive significant relationship between claustrophobia behavior and earthquake risk perception and its affective and cognitive sub-dimensions. In other words, individuals with high claustrophobia behavior also have high earthquake risk perception.
Conclusion: As a result, it was seen that education status and gender have significant differences on earthquake risk perception, and significant relationship between affective and cognitive earthquake risk perception and claustrophobia.
Economic Growth and Female Labor Participation in Islamic Countries: Evidence from Labor Kuznets Curve
Authors: Kavakcı Saime
Published: December 2024

As a result of industrialization and various economic developments, female participation in the labor force has been ensured and this participation has increased day by day. Public, and private sector representatives make various investments, especially for including females in the labor force. There are many studies in the literature on the relationship between female participation in the labor force and economic development processes. The main question of this study is whether it is possible to differentiate the U-shape, which is realized as pre-industrial and post-industrial in modern countries, in Islamic countries. Contrary to the existing literature, the study argues that there is an inverted U-shaped (Kuznets curve) relationship between female labor and economic growth in Islamic countries, not a U-shaped relationship. Accordingly, it is argued that women in Islamic countries join the labor force when the economy is deteriorating and leave the labor force when the economy is improving. Within the framework of this hypothesis, the study investigates the Kuznets curve relationship between female labor force participation and economic development using data from 39 Islamic countries between 1990 and 2019. The study employs panel data analysis, a quantitative research method, to explore this relationship. As a result of the study, the Kuznets curve was found in at least one model in Iran, Kazakhstan, Lebanon, Morocco, Pakistan, Kyrgyz Republic, Maldives, Mali, Mauritania, Sudan, Tunisia, Senegal and Comoros. The U-shaped feminization hypothesis is confirmed in at least one model in Algeria, Azerbaijan, Bangladesh, Indonesia, Iraq, Jordan, Malaysia, Oman, Türkiye, Yemen, UAE, Burkina Faso, Uzbekistan, Tajikistan, and Turkmenistan. In line with the study's claim, some Islamic countries represent the Kuznets curve contrary to the general feminization U theory. Religion, culture, and legal codes are thought to be the reason behind the Kuznets curve found between female labor force participation rate and economic development.
Zihinsel Yankıların İki Yüzü: Tefekkür ve Ruminasyon Arasındaki Çizgi
Authors: Aka Muharrem
Published: December 2024

Tefekkür; bireylerin olayları daha geniş bir perspektiften değerlendirmesini, içsel refahını ve zorluklarla daha esnek bir şekilde başa çıkma kapasitesini destekleyen önemli bir zihinsel süreçtir. Ruminasyon ise bireylerin sürekli olarak olumsuz düşüncelere odaklanmalarını ve bu düşünceleri tekrar tekrar zihinden geçirmelerini ifade eden bir kavramdır. Ruminasyon, bireyin mevcut anı yaşamasını engelleyerek, sürekli bir stres kaynağı yaratır ve bu da genel yaşam kalitesini düşürür. Bu çalışma, tefekkür ve ruminasyon kavramlarını zıt kutuplarda bulunan iki ayrı düşünme biçimi olarak irdeleyerek, bu düşünme biçimlerinin bireylerin bilişsel ve duygusal deneyimleri üzerindeki etkilerini derinlemesine incelemeyi ve söz konusu kavramlar arasındaki farklılaşmayı ortaya koymayı amaçlamaktadır. Bu çalışmanın ana hedefi, tefekkür ve ruminasyonun bireylerin günlük yaşamlarındaki, psikolojik iyi oluşlarındaki ve genel zihinsel sağlıklarındaki rollerini anlamaktır. Araştırmada, nitel araştırma yöntemlerinden biri olan doküman analizi tekniği kullanılmıştır. Bu kapsamda, tefekkür ve ruminasyon kavramlarına ilişkin literatürdeki kuramsal ve ampirik çalışmalar incelenmiş, bu iki kavramın bireylerin bilişsel ve duygusal süreçleri üzerindeki etkilerini anlamaya yönelik bir teorik çerçeve oluşturulmuştur. Araştırma deseni, tefekkür ve ruminasyonun olumlu ve olumsuz etkilerini ayrıntılı bir şekilde karşılaştırmayı hedefleyen betimsel bir analiz yaklaşımına dayanmaktadır. Araştırmanın bulguları, tefekkürün bireylerin olayları daha geniş bir perspektiften değerlendirmelerine olanak tanıyarak duygusal dengeyi korumalarına ve psikolojik dayanıklılıklarını artırmalarına katkıda bulunduğunu göstermektedir. Buna karşılık, ruminasyon bireylerin olumsuz düşüncelere sürekli odaklanmalarına yol açarak zihinsel strese ve yaşam kalitesinde düşüşe neden olmaktadır. Çalışma, tefekkürün sağlıklı düşünme ve duygu yönetimi süreçlerini desteklediğini, ruminasyonun ise bireylerin zihinsel sağlıklarını olumsuz etkilediğini ortaya koymaktadır. Araştırmanın sonuçları, tefekkürün bireylerin psikolojik sağlığı üzerindeki olumlu etkilerini, ruminasyonun ise olumsuz etkilerini vurgulamaktadır. Bu bağlamda, tefekkürün sağlıklı düşünme ve duygu yönetimi süreçlerine olan katkısı, ruminasyonun olumsuz etkileriyle birlikte ele alınarak, bireylerin zihinsel sağlıklarını güçlendirmeye yönelik stratejilerin geliştirilmesine ışık tutması beklenmektedir. Bu çerçeve, araştırmanın daha geniş bir akademik bağlamda değerlendirilmesine olanak tanımaktadır.

Authors: Yılmaz Orhan
Published: December 2024

Ülkemizde üniversite sınavına hazırlanan veya üniversite okuyan yahut boş gezen gençlerin en fazla mustarip oldukları konulardan biri, geleceğe dair kaygı ve korkulardır. İyi bir okula yerleşememe, sınavlarda başarısız olma veya bir işe girememe korkusu ve kaygısı gençlerimizin başarısını, azmini ve yaşama sevincini olumsuz yönde etkilemektedir. Kontrol altına alınması halinde başarı ve huzur getirecek olan bu fıtri duygular ciddi huzursuzluklara yol açmaktadır. Sağlıklı ve huzurlu bir hayata erişebilmek için bu tür kaygı ve korkuların kontrol altında alınması önem arz etmektedir. Gençlik dönemlerinde kaygı ve korku duygularını makul düzeyde tutup kontrol altına alabilmek için özel bir çaba gerekmektedir. Bu mücadelenin çok farklı yolları ve şekilleri olabilir. Bir uzmandan yardım alma, spor ve sanata yönelme, sosyal aktiviteleri artırma, meditasyon yapma, seyahate çıkma, toprakla uğraşma vb. ilk akla gelen önerilerdir. Hayata dair kaygı sorununa karşı eğitimciler ve psikologların önerdiği bu tür aktiviteler ülkemizin sosyal ve ekonomik yapısı dikkate alındığında herkese hitap etmeyebilir. Bu sorunu aşmak için daha kolay ve kabul gören, herkesin rahatlıkla uygulayabileceği bir metoda ihtiyaç duyulmaktadır. Bize göre bu da Kur’an ve Sünnet merkezli doğru bir din eğitimidir. Özellikle Hz. Peygamber’in (sav) yaşantısını ve sözlerini konu alan hadisler içinde insan psikolojisini müspet yönde etkileyen, duyguları kontrol altına almada yardımcı olan pek çok hikmetli söz ve eyleme rastlanmaktadır. Terapi etkisi yapacağını düşündüğümüz bu hadislerin tespit edilmesi ve güncel yorumlar ışığında kişisel gelişim ve nefis terbiyesi sahasında kullanılması önem arz etmektedir. Bu çalışmada kaygı ve korku duyguları ile mücadelede dini referansların önemi dile getirilmiş, tavsiye ve telkin içerikli hadislerin etkileri üzerinde durulmuştur.

Published: December 2024

As algorithmic decision-making systems (ADMS) are increasingly deployed across various sectors, the importance of research on fairness in Artificial Intelligence (AI) continues to grow. In this paper we highlight a number of significant practical limitations and regulatory compliance issues associated with the application of existing bias mitigation methods to ADMS. We present an example of an algorithmic system used in recruitment to illustrate these limitations. Our analysis of existing methods indicates a pressing need for a change in the approach to the development of new methods. In order to address the limitations, we provide recommendations for key factors to consider in the development of new bias mitigation methods that aim to be effective in real-world scenarios and comply with legal requirements in the European Union, United Kingdom and United States, such as non-discrimination, data protection and sector-specific regulations. Further, we suggest a checklist relating to these recommendations that should be included with the development of new bias mitigation methods.

Authors: Kayakuş Mehmet
Published: December 2024

In this study, the impact of mobile applications developed by the Ministry of Health of the Republic of Turkey as part of its digitalization strategy on corporate reputation is analysed by using artificial intelligence methods through user comments. Within the scope of the research, the last 300 user comments of MHRS, Hayat Eve Sığar and eNabız applications on Google Play were analysed, and sentiment analysis and text mining techniques were applied. The findings reveal that MHRS and eNabız applications are generally perceived positively by users, which has a positive impact on the corporate reputation of the Ministry of Health. 81% of MHRS users and 73% of eNabız users made positive comments about the applications. However, for the Hayat Eve Sığar application, the positive comment rate remained at 51 percent, and more technical problems were reported. This shows that the application offers complex user experiences and needs to be improved. In conclusion, it is emphasized that the mobile applications of the Ministry of Health have strengthened its corporate reputation in general, but user satisfaction and sustainability of technical performance are critical to maintaining this reputation.
Antifungal Effect of Cinnamon Bark Extract on the Phytopathogenic Fungus Fusarium sporotrichioides
Authors: Martinko Katarina , Mioč Eni
Published: December 2024

Research background. The use of plant extracts in the biological control of fungal plant diseases can reduce the use of fungicides and residues in food by effectively suppressing mycotoxigenic microorganisms. The focus of interest is therefore finding plant extracts that have antifungal properties and are not toxic to organisms, so that they can be used for the biological control of economically important phytopathogenic fungi such as Fusarium. Species of the genus Fusarium are considered economically important pathogenic fungi of numerous agricultural crops, which not only cause significant losses but also produce mycotoxins that reach consumers through food. One of the most important species of this genus is the species Fusarium sporotrichioides, which causes economically significant damage to a large number of agricultural crops.
Experimental approach. In this laboratory study, the influence of aqueous cinnamon bark extract on the growth and development of the toxicogenic fungus F. sporotrichioides was investigated using the poisoned food technique. For the study, the aqueous extract of cinnamon bark was obtained by ultrasound-assisted extraction and the content of antifungal compounds was detected by phytochemical tests.
Results and conclusions. The research results confirm a significant inhibition of the growth of the pathogen when grown individually on a potato-dextrose agar (PDA) medium with 3 and 5 % extract. The antifungal effect of the extract was demonstrated by microscopic analysis of the pathogen, which showed significant deformation of hyphae and a change in the mycelium colour after seven days of growth on medium with 5 % extract, resulting in a threefold higher inhibition of pathogen growth than growth on medium with 3 % extract. The microscopic changes also show a reduction in pathogen sporulation and a possible reduction in mycotoxin production. Phytochemical tests confirmed the presence of antifungal compounds in the extract.
Novelty and scientific contribution. Based on the obtained results, the aqueous extract of cinnamon bark shows a fungistatic effect on the growth and development of F. sporotrichioides, which opens the possibility of continuing research of cinnamon compounds as potential compounds of future control agents for the suppression of fungi of the genus Fusarium.

Published: December 2024

Research background. Anthocyanin pigments in mangosteen pericarp can serve as natural colourants; however, their stability is compromised by enzymatic browning caused by polyphenol oxidase (PPO). Thus, this study aims to investigate how hot water and steam blanching affect the PPO activity, phenolic profile and antioxidant properties of mangosteen pericarp.
Experimental approach. Fresh mangosteen pericarp was blanched in hot water or steam at 100 °C for 0, 30, 60, 90 and 120 s and the residual PPO activity, total phenolic content (TPC), total anthocyanins, antioxidant activity, browning index and colour properties were evaluated. Additionally, the phenolic compounds were identified using liquid chromatography-mass spectrometry (LC-MS).
Results and conclusions. Zero-order reaction kinetics (R2>0.800) showed that residual PPO activity was significantly (p<0.05) reduced in both blanched and steamed mangosteen pericarp. As expected, PPO was inactivated more rapidly in hot water (t1/2=59.0 s) than in steam blanching (t1/2=121.1 s). However, the principal component analysis (PCA) showed that steam blanching for 90 s was the most efficient method, preserving the highest levels of antioxidant capacity, expressed as Trolox equivalents (TE; 9135 μmol/g), Fe(III)-reducing power, expressed as TE, (9729 μmol/g), total anthocyanins (3.03 mg/g), and TPC, expressed as gallic acid equivalents (1057 mg/g). Overall, steam blanching for 90 s was the most efficient method because it best preserved the phenolic compounds and is also a cost-effective method compared to hot water, which needs to be replaced after a few applications.
Novelty and scientific contribution. This is the first study to report the effects of blanching on the anthocyanins mainly present in mangosteen pericarp, in particular cyanidin-3-O-sophoroside (C3S) and cyanidin-3-O-glucoside (C3G), using high-performance liquid chromatography (HPLC) and LC-MS. This study makes a significant scientific contribution to the food industry by providing suitable blanching methods to preserve the quality of bioactive compounds, especially anthocyanins in mangosteen pericarp, which can be used as a natural colourant.

Published: December 2024

Over the last decades, eating habits have shifted towards convenient foods with shorter preparation times due to people’s busy lifestyles and higher living standards. Rapid changes in dietary patterns and lifestyles with the industrialization and globalisation have led to the escalating incidence of chronic diseases, which has paved the way to greater interest in dietary changes regarding nutritional status and health benefits. Composite flour is a combination of wheat and non-wheat flours or exclusively non-wheat flour with improved nutritional value, therapeutic properties and functional characteristics. The application of composite flours in the food industry is an important milestone that maximises the use of indigenous crops while optimising the product quality, nutritional value, organoleptic properties and consumer acceptance. This paper provides a comprehensive overview of the suitability and compatibility of alternative composite flours in the food industry with regard to the existing formulations. Furthermore, the suitability of composite flours in food products in terms of nutritive and therapeutic value is emphasised. It was found that food products with higher nutritional and therapeutic value and acceptable sensory properties
can be formulated by blending different non-wheat flour sources with wheat flour at different ratios. Composite flours have the potential to reduce the risk of non-communicable diseases, particularly type 2 diabetes, cardiovascular disease and cancer. It can be concluded that the use of composite flours in the food industry is a trending approach due to their numerous benefits.

Published: December 2024

Research background. Given the potential of microbial exopolysaccharides from lactic acid bacteria in various industrial processes, alternative sources for the isolation of lactic acid bacteria are highly topical. In this study, we used a traditional sourdough from einkorn (Triticum monococcum L. ssp. monococcum) as a source of lactic acid bacteria for the isolation, identification and determination of exopolysaccharide producers.
Experimental approach. The sourdough was prepared from einkorn according to the traditional method. Lactic acid bacteria were isolated and purified using the single colony technique on MRS and M17 media. The isolates were characterised using matrix-assisted laser desorption ionization-time of flight mass (MALDI-TOF) spectrometry. All isolates were analysed for extracellular polysaccharide production and one isolate was selected for purification and characterisation of its polysaccharide.
Results and conclusions. The isolates were identified as Lactobacillus plantarum, L. paraplantarum, L. brevis, Pediococcus pentosaceus, Enterococcus faecium and E. durans. The production of exopolysaccharides by all lactic acid bacteria was evaluated and it was found that all strains (except one) were capable of producing exopolysaccharides. One polysaccharide (EPS-SL70) was purified from the isolates of E. durans SL70. This anionic heteropolysaccharide had, in addition to the carbohydrate backbone, a protein structure that did not contain nucleic acid. The carbohydrate backbone consisted of mannose, glucose, rhamnose, arabinose, xylose and galactose.
Novelty and scientific contribution. The microbial flora of traditional einkorn sourdough has been identified in this study and represents the first report on the exopolysaccharide production by lactic acid bacteria in traditional einkorn sourdough. Additionally, Enterococcus durans from einkorn sourdough was identified as a new exopolysaccharide producer.

Facades, in addition to their aesthetic function, play a fundamental role in the preservation of a building, acting as a protective barrier against external aggressive agents. Therefore, maintenance activities are essential to prolong the lifespan of this system and prevent the degradation of its components. When it comes to historical heritage, beyond the sustainability brought by maintenance activities, conserving the architectural richness of a specific era is vital for the history and culture of a place. The damage map is a crucial document for developing a restoration project for historical and religious buildings. The present research was developed with the purpose of stimulating the appreciation of heritage riches and collaborating with the development of actions aimed at the preservation and conservation of the National Cultural Heritage, through the creation of a damage map and analysis of the pathological manifestations of the facades of the Madre de Deus Church, Recife/PE. The Madre de Deus Church was selected based on criteria such as: classification by the National Historic and Artistic Heritage Institute; social importance; accessibility; and data availability. Research on the building's history and visual inspections were carried out. The main manifestations identified were dirt/biofilm and stains due to the presence of moisture. The South Facade is the most critical of the building, requiring more significant interventions for restoration, which may be related to the higher incidence of winds and rains.

Municipalities play a key role in the public policy cycle because they are directly involved in managing their respective territorial areas. When it comes to solid waste in Brazil, one significant way to mitigate its impacts is through public participation in the National Solid Waste Policy, established by Law No. 12.305 of 2010. Municipal plans serve as the planning and implementation documents for this policy. In this context, the municipality of Araraquara was chosen as the case study, given its solid waste management system and its history of progressive municipal governance. This study aimed to understand whether and how institutionalized public participation occurred through the Municipal Council for the Defense of the Environment (COMDEMA) during the formulation of the Municipal Plan for Integrated Solid Waste Management between 2011 and 2021. To achieve this, we conducted a bibliographic review, documentary research, and semi-structured interviews, analyzing the data using Laurence Bardin's content analysis technique. The results indicate that, although the management instrument explicitly mentions participation, COMDEMA’s input did not effectively translate into decisions by the council regarding the plan formulation during the period analyzed. This was due to the vulnerabilities within the council’s structure, which hinder the inclusion of solid waste issues in meetings for discussion and decision-making. Hopefully, this research will foster further discussions about COMDEMA and its role in solid waste management.

The objective of this study was to evaluate the use of shellfish shell waste as an adsorbent in the treatment of textile effluent. The collected shells were washed with running water and dried in an oven. Part of the washed and dried shell was crushed and sieved to obtain grains of 0.6 mm, while the remaining portion was ground, thermally treated in a muffle furnace, and sieved to obtain grains of 0.3 mm. The point of zero charge of the adsorbent was determined, and the equilibrium of the solution was performed by preparing solutions containing 50 ml of raw textile effluent and varying masses of each bioadsorbent (1, 2, and 3 g) at different pH values (7.19 and 9.00). The solutions were stirred and then filtered through qualitative absorbent paper. The color, turbidity, and adsorption capacity were measured and calculated. Based on the best result found for the mass of bioadsorbent used, it was added to a solution of 50 ml of raw effluent and stirred for 0, 5, 10, 20, 30, 40, 50, and 60 minutes. The samples were filtered, and the color and turbidity of each were measured, with the adsorption capacity recalculated. The results showed that the calcined shell achieved better results than the natural shell, with the optimal masses being 1.0 g and 2.0 g, respectively. The pH of the solution had little influence on the results. As for the contact time, the best results were observed between 0 and 20 minutes.

Published: December 2024

This study investigated the feasibility of using Post-Consumer Recycled Polyethylene Terephthalate (PCR-PET) as an alternative aggregate in mortar for civil construction, aiming to evaluate its properties and impact on the sector's sustainability. Compressive strength, substrate adhesion, workability, and water retention tests were conducted on mortars with PCR-PET addition, and the results were compared with conventional mortars and the requirements of the ABNT NBR 13281 standard. The results showed that adding PCR-PET to mortars led to a slight reduction in compressive strength and substrate adhesion; however, the values remained within the limits set by the standard. Workability and water retention of mortars with PCR-PET were similar to conventional mortars. This study contributes to the field of civil construction by presenting PCR-PET as a viable and sustainable alternative for the use of plastic waste in civil construction, contributing to the reduction of demand for natural resources and waste generation. However, further studies are needed to assess the mechanical behavior and durability of mortars with PCR-PET in the long term, as well as their complete environmental impact.

The objective of this study was to analyze the National Policy of Civil Protection and Defense – PNPDEC (Law No. 12,608/2012) and Urban Policy as urban planning instruments for disaster risk reduction at the municipal level, with the purpose of understanding the various interactions among land use characteristics, public policies, and disaster risks. The research consisted of a literature review, based on data collection from existing legislation, as well as official publications produced by government agencies and bodies in support of Civil Protection and Defense, as well as at the municipal level. The municipality of Aracaju (SE) was considered as a case study, particularly the Jabotiana neighborhood, which, due to the intensification of urbanization in the last two decades (2000-2020), has been experiencing a serious socio-environmental problem that, coupled with the inefficiency of sanitation, has favored the occurrence of floods. It is noted that the most vulnerable segment of the population suffers the consequences of such events with greater intensity, due to their lower capacity to cope with disasters compared to the more affluent population, since the latter may inhabit the safer parts of the city, less exposed to risks. These conditions result from the lack of restriction through the Urban Development Master Plan (PDDU), which is outdated and incompatible with the urban reality of Aracaju, and from irregular and precarious occupation in Risk Areas and Permanent Preservation Areas.

The term “bioclimatic architecture” emerged in the 20th century from studies and analyzes carried out by brothers Victor and Aladar Olgyay, pioneers in the discussion. They played a crucial role in the development of concepts and principles that integrate natural resources, such as ventilation, shading and natural lighting, among others, into architectural practice, aiming to design more sustainable, comfortable and energy-efficient buildings. The main objective of this article is to identify and analyze the bioclimatic strategies implemented at the Robert Schuster Residence (1978), located in Manaus, Amazonas. The methodological approach of the study is based on two stages: the first consists of a bibliographical review, aiming to assist in the design description of the object of study. The second part comprises the analysis of the bioclimatic strategies for natural ventilation and shading recommended by the platform “Designing Energy Efficient Buildings” - Projeteee (2023) for the city of Manaus, Bioclimatic Zone 8, in order to identify them in the Robert Schuster Residence through floor plan diagrams, sections and design analysis.

This study aims to analyze the effects of partial replacement of natural aggregate with Post-Consumer Recycled Polyethylene Terephthalate (PCR-PET) in screed mortars, emphasizing both acoustic performance and compressive strength. The research adopts a methodological approach that encompasses material characterization to performance evaluation in terms of strength and acoustic attenuation. The originality of the work lies in the comprehensive analysis of the physical and mechanical properties of mortars, focusing on the effectiveness of replacing natural aggregate with PCR-PET. The results indicate that as the proportion of PCR-PET in the mix increases, the apparent density decreases, directly impacting compressive strength. Additionally, there is an improvement in sound absorption in mortars with higher substitution of sand by PCR-PET, highlighting positive implications for the acoustic performance of these materials. Theoretical and methodological contributions include a deeper understanding of mortar properties, while social and environmental implications reside in promoting sustainable practices in construction, emphasizing the potential use of recycled materials.

The term Resilience is present in both academia and management; however, Urban Water Resilience (UWR) is still a term that has been scarcely studied, addressed, systematized, and applied in research related to water resources management. The present work was motivated by the need to obtain interpretative data for the UWR, considering its potential and importance regarding the construction of Resilience in the face of climate change. The objective is to propose guidelines and strategies to incorporate UWR in municipalities based on the use of indicators. To this end, the researchers initially sought the direct or indirect presence of UWR in Municipal Plans of Brazilian cities. In the next stage, Urban Water Systems were analyzed based on the Components and Variables related to UWR and Indicators associated with the systematized Variables were suggested, the aforementioned having being used in the proposed method for incorporating UWR. The systematization carried out resulted in fifteen Components and thirty-nine Variables for which fifty-three Indicators were proposed that allow monitoring of UWR. The proposed methodology will enable cities to evaluate the present and build the future by becoming water-safe cities.

Published: December 2024

This article analyzed the effects of surface roughness on the variability of natural ventilation within urban canyons, based on the variation of two morphological parameters: The H/W ratio, based on the space between buildings, and the orientation of the roads (N = 0°/ N = 45°). As an object of study, the city of Arapiraca, with a tropical savannah climate (As), located in the semi-arid region of Alagoas, is located. The methodology adopted was based on predictive analysis, through computer simulation, using the ENVI-met v.4 Beta software. 18 hypothetical urban scenarios were elaborated, which varied in terms of the application of initial and progressive minimum setback to the number of floors, with incidence of predominant perpendicular (N = 0°) and oblique (N = 45°) ventilation to the buildings, for the hot and dry period. The climatic performance of the canyons was evaluated, quantitatively and qualitatively, through wind speed and direction data at 3 p.m., at a height of 1.5 m from the ground. The results showed that the scenarios with low surface roughness, with the application of progressive setback, buildings of different heights and incidence of the predominant oblique ventilation to the buildings, presented more favorable conditions for the use of natural ventilation for thermal comfort outdoors, at the pedestrian level. In view of the results found, the need for urban planning guidelines that are aligned with local bioclimatic strategies and the precepts of urban sustainability and resilience is highlighted.

This study aims to diagnose the pathological manifestations of the Brum Chapel, using four methodological steps, namely: characterization of the area, diagnosis, damage mapping, and guidelines for the restoration project. The case study was carried out at the Brum Chapel, located in the city of Recife/PE, in the northeast region of Brazil between 2020 and 2021. In this way, the research was able to guarantee the preservation and dissemination of facts and historical achievements of the Brazilian Army (responsible for the property), extolling the participation of the northeastern soldier in all historical episodes in the state of Pernambuco, providing culture and knowledge to visitors, in addition to recognition at the regional level, as a preservation agency and an example of conservation of military-religious architecture from the 17th century. The results obtained demonstrated the natural process of evolution of pathological manifestations, raising awareness of heritage management for planning and carrying out maintenance, enabling the compatibility of the building's needs with the available financial resources. It is concluded that in this process, public policies should make these actions viable through tax incentives that allow for the proper conservation of this property, respecting its original function.
Impactos ambientais e sociais das cavas subaquáticas na disposição de sedimentos contaminados

Published: December 2024

The installation of underwater pits is today a common procedure, adopted by several countries around the world for the disposal of contaminated sediments resulting from dredging and industrial activity. In Baixada Santista, more specifically in the Piaçaguera Channel, an underwater pit was built for the same purpose, despite the protests that arose. This dispute arises from the fact that these contaminated sediments can cause environmental and social damage in areas close to their installation. This article aims to evaluate the environmental and social impacts of underwater pits used for the disposal of contaminated sediments, focusing on the Santos-São Vicente estuary. By adopting a bibliographical research methodology, it was possible to verify that environmental impacts are related to the possible contamination of waters, marine fauna and, consequently, human beings. Considering that the communities carry out their activities in the region affected by the construction of the pit, in the event of any problem resulting from contamination, the social impact is also important.

The non-serialized nature of the construction industry, the dynamic environment of construction sites, and the high turnover of workers are conditions that hinder the application of knowledge management (KM) in the sector. Given this, several studies highlight the use of BIM as a platform capable of optimizing KM. The main objective of this study was to investigate the potential of BIM for KM in construction. To this end, a systematic literature review was conducted, revealing a variety of practical applications of BIM in KM in areas such as occupational safety, project management, and sustainability in facilities management. However, studies are still in the early stages, with limited activities and risks included in the analyses. Moreover, ontology is widely used to structure knowledge in conjunction with a BIM model, followed by case-based reasoning (CBR). Although BIM can optimize KM, its application needs to be scaled up. Future studies should explore the use of machine learning to accelerate the knowledge modeling process.

Published: December 2024

Urban areas are expanding rapidly, and the lack of appropriate urban planning has resulted in environmental impacts, compromising the health of cities and their inhabitants. In this context, the concept of Smart Cities, through the use of Information and Communication Technologies (ICTs), can help public managers to outline more assertive strategies for city problems through the measurement of urban indicators. Therefore, the objective of this research is to analyze the health and mobility indicators of Passo Fundo/RS and their relationship with the epidemiological data of COVID-19. The methodology used in this research was a comparison between Passo Fundo’s health and mobility indicators and the same indicators from medium-sized cities in the South of the country best classified in the Connected Smart Cities Ranking of 2021, 2022 and 2023. Soon after, the survey was carried out of the rates of infections and deaths resulting from COVID-19 in these same cities. From the results it was possible to verify that some of the main weaknesses in relation to mobility are public transport and low incentive for active mobility. In the health area, the city presented some satisfactory results, but lacks investment in family health programs and updates to the online medical consultation process. In relation to epidemiological data, it was noticed that the cities best classified in the Ranking had a better fight against the pandemic by implementing ICTs in the consultation management process.
