Authors: Anisah Citra Nur , Saptono Sigit
Published: January 2024

Misconception is an understanding that is not in accordance with the concept conveyed by experts. Misconceptions are still found in student learning outcomes on the Circulatory System material. The Concept Attainment Model is a teaching strategy that helps students strengthen their understanding of the concepts being studied. Learning independence is one of the factors that influence learning outcomes. The purpose of this study was to increase student independence and learning outcomes as well as reduce students' misconceptions about the Circulatory System material. This research is a pre-experimental research with a one group pretest-posttest design. The data in this study were obtained through observation sheets, student response questionnaires, pretest-posttest, and student interviews. The results showed that prior to the implementation of the Concept Attainment learning model, students' learning independence was classified in the medium category. After the implementation of the Concept Attainment learning model, student learning independence increased, belonging to the high category. Student learning outcomes show that prior to the implementation of the Concept Attainment learning model, they had not reached the specified classical mastery. That is, student learning outcomes are low. After implementing the Concept Attainment learning model, student learning outcomes experienced a good increase in the medium and high N-Gain categories. The findings of students' misconceptions prior to the implementation of the Concept Attainment learning model were found in the concept of the mechanism of the clotting process, the link between blood type and blood transfusion, parts of the heart in cardiac anatomy, differences in the systemic and pulmonary circulatory systems, and disorders/abnormalities of the circulatory system. After implementing the Concept Attainment learning model, misconception were found in the concept of blood constituent components, the relationship between blood type and blood transfusion, and disorders/abnormalities of the circulatory system. Thus, it can be concluded that the implementation of the Concept Attainment learning model can increase student independence and learning outcomes and reduce student misconceptions.

Identifying a high-risk fighter in boxing
Authors: K Sethi Nitin
Published: January 2024

Boxing is one of the most popular of combat sports. The goal in boxing is to win by causing a knockout (KO). Every punch thrown at the opponent’s head is thrown with this intention. As a result boxers experience numerous head impact exposures (HIE) both in and out of competition. The sport carries a high incidence of acute and chronic traumatic brain injury (TBI) as well as occasional disabling orthopedic and ophthalmological injury. While no fighter (combatant) is immune to these injuries, there are fighters who for various reasons are more susceptible to these injuries or in whom these injuries carry high morbidity and mortality. These fighters are colloquially referred to as “high-risk fighters”. A high-risk fighter needs closer medical supervision before, during and after a bout. In this commentary an attempt is made to identify these high risk fighters.

Published: January 2024

The difficult situation in eastern Ukraine has made the problem of assessing potential man-made threats more urgent. Among the many industrial enterprises that suffered damage as a result of hostilities, the most environmentally hazardous ones were identified, namely: Yasinivka, Avdiivka, and Yenakiieve coke-chemical plants; Yenakiieve, Makiiivka, and Donetsk metallurgical plants; Alchevsk metallurgical plant; Lysychansk oil refinery; Donetsk state chemical plant; Sloviansk, Luhansk, Vuhlehirsk, and Myronivka thermal power plants; chemical industry enterprises such as Severodonetsk Azot plant and Horlivka Styrol plant. The work proposes a method for assessing threats to critical infrastructure objects from enemy attacks. By applying graph theory and probability theory, the proposed method allows for obtaining quantitative assessments of threats and analyzing possible scenarios to develop cascading effects of emergencies. This helps determine the potential consequences of an attack and evaluate the risks associated with damaging critical infrastructure. The proposed model is based on a structural-logical approach that considers the inter- relationships between different components of the natural-technological geosystem. It will enable obtaining more objective and reliable results when assessing potential military-technological threats to CIOs and analyzing possible cascading effects in the event of damage to these objects. Developing such a model is essential in improving the approaches to assessing threats to CIOs, providing more accu- rate forecasts, and effective risk management. The results of this research can be useful for practical applications in developing strate- gies for the security of CIOs in the context of armed conflict. The results obtained in this work can be useful in developing models for assessing ecological and technological threats to critical infrastructure objects, particularly in the context of military operations. This method will improve the level of protection and help develop effective strategies to counter potential threats to critical infrastructure.

A nyaki nyirokcsomó-megnagyobbodás gyakori jelenség gyermekkorban. A benignus,
átmeneti kórképek mellett a tünetek hátterében súlyos kórállapotok is állhatnak.
A szerzők egy 12 éves fiúgyermek esetét mutatják be, aki több hónapja fennálló,
progrediáló nyaki nyirokcsomó-megnagyobbodás miatt került klinikai felvételre. A
laboratóriumi vizsgálatok malignitásra nem utaltak, a pontos etiológia
tisztázása céljából biopsziás mintavétel történt. A szövettani vizsgálat
immunglobulin-G4-hez (IgG4) társult betegséget mutatott. A szövettani vizsgálati
eredményt a kórképre jellegzetes laboratóriumi eredmények, illetve a jellegzetes
bőrfolyamat is alátámasztotta. Egyéb szervi manifesztáció kizárására
pozitronemissziós tomográfiás (18FDG-PET/CT), illetve hasi mágneses
rezonanciás (MR-) vizsgálat történt. A beteg szteroidkezelésben részesült,
melynek hatására az organomegalia csökkenése volt detektálható. Az aktivitási
tünetként értékelt fokozódó ichthyosiform bőrfolyamat és perzisztáló
lymphadenopathia miatt mikofenolát-mofetil-kezelés került bevezetésre, mely
hatásosnak bizonyult: mind a klinikai tünetek, mind a laboratóriumi paraméterek
alapján tartós remisszió észlelhető. Esettanulmányunk a gyakori klinikai
tünetként ismert nyaki lymphadenopathia hátterében álló ritka kórképre hívja fel
a figyelmet. A kórkép diagnózisának felállításában a képalkotó vizsgálatok
mellett speciális laboratóriumi vizsgálatok, illetve a szövettani lelet
segíthet. A betegség kezelésében a szervi manifesztációk mértékének függvényében

Cu2ZnSnS4/N-MWCNTs hybrid systems as counter electrode substitutes for platinum in dye-sensitized solar cells
Authors: Mxakaza Lineo , Ngubeni Grace , Moloto Nosipho , Tetana Zikhona
Published: January 2024

Copper zinc tin sulfide, Cu2ZnSnS4 (CZTS) is being considered a viable option for a counter electrode due to its abundance, cost-effectiveness, catalytic activity, and other advantageous properties. However, CZTS has low electron transport capabilities, a shortcoming that can be addressed by combining it with high electron mobility carbon nanomaterials. Nitrogen-doped multi-walled carbon nanotubes (N-MWCNTs) exhibit higher electron conductivities than their pristine counterparts. This improvement is attributed to the disruption of the sp2-hybridized carbon arrangement, as some of the carbon atoms are replaced by nitrogen atoms. In this study, a counter electrode composed of a 70% CZTS and 30% N-MWCNTs mixture produced a higher electrochemical current density compared to the individual materials. This suggests that it is more electrocatalytic than CZTS and N-MWCNTs alone, ultimately leading to the highest power conversion efficiency of 6.52%.

THE IMPACT OF TEMPERATURE AND ANTIOXIDANTS ON OXIDATION AND THE FORMATION OF TRANS FATTY ACIDS IN SEVERAL PALM OIL DERIVATIVES
Authors: Saragih Martua Haojahan , Silaban Saronom , Eddiyanto Eddiyanto
Published: January 2024

The quality of palm oil is strongly influenced by temperature. The oxidation of palm oil can be caused by high temperatures. The higher the storage temperature, the faster oxidation occurs. In this research, the temperature significantly affects the quality of several palm oil derivative products such as Palm Olein, Palm Stearin, Palm Kernel Oil, and Palm Kernel Stearin. Antioxidants are very effective in resisting the increase in the oxidation reaction of some palm oil commodities. With the addition of tertiary butylhydroquinone (TBHQ) or butylated hydroxytoluene (BHT), the increase in peroxide value, p-anisidine values, free fatty acid, color tends to be slower than without the addition of antioxidants. For PV, BHT was the most effective antioxidant for RPKOL at a 29.75% increase, RBDOL at 9.91%, and RBDST at 5.26% but for RPKS TBHQ was the most effective increase at 19.83%. For anisidine value, TBHQ+BHT was most effective for RPKOL with a 61.62% increase, TBHQ for RPKS with 76.76%, BHT for RBDOL and RBDST with 15.37% and 14.46%. In the FFA test, BHT was effective for RPKOL and RPKS with a percentage increase of 6.48% and 6.67%, but TBHQ was effective for RBDOL and RBDST to controlled FFA with an increase of 8.41% and 3.38%. In color testing, TBHQ proved to be the effective antioxidant for RPKOL and RBDOL, resulting in percentage increases of 8.71% and 2.13%, respectively. For RPKS, the combination of TBHQ and BHT was employed, resulting in no percentage increase (0%). Additionally, BHT at 3.85% was used for RBDST. At a temperature of 130°C, an oxidation process was observed, indicating the formation of an aldehyde compound. This was evidenced by the FT-IR spectrum, showing peaks at wave numbers 1760 cm⁻¹ (C=O of aldehyde) and 2900 cm⁻¹ (CH on aldehyde). In this research, we can also see the formation of trans fatty acids C18:1n9t in GC-FID's peak area

Published: January 2024

Kondisi wilayah pesisir yang kaya potensi ternyata tidak berbanding lurus dengan tingkat kesejahteraan masyarakat di wilayah pesisir, hal tersebut juga terjadi di Provinsi Daerah Istimewa Yogyakarta (DIY). Kegiatan pariwisata merupakan salah satu solusi untuk meningkatkan kesejahteraan masyarakat, namun disisi lain perkembangan kegiatan pariwisata baharí di wilayah pesisir DIY masih menghadapi berbagai permasalahan lingkungan. Salah satu konsep yang dapat diterapkan untuk mengatasi permasalahan di wilayah pesisir adalah ekonomi biru atau Blue Economy (BE), yaitu pemanfaatan sumber daya laut secara berkelanjutan untuk meningkatkan kesejahteraan masyarakat dengan mengoptimalkan pariwisata yang berkelanjutan. Tujuan penelitian ini adalah untuk menganalisis potensi penerapan BE dan strategi pengembangan pariwisata berkelanjutan di wilayah pesisir DIY. Penelitian ini dilaksanakan dalam kurun waktu 5 bulan, mulai bulan Januari sampai dengan Mei 2023. Pengumpulan data menggunakan literature review dan wawancara dengan Dinas Kelautan dan Perikanan, Bappeda dan Dinas Pariwisata DIY. Data kemudian dianalisis dengan menggunakan indikator penerapan BE yang merupakan kombinasi Indeks Kesehatan Laut Indonesia (IKLI) dan Ocean Health Index (OHI). Strategi pengembangan dianalisis menggunakan matriks Strengths, Weaknesses, Opportunities dan Threats (SWOT). Hasil analisis menunjukkan potensi penerapan ekonomi biru dalam mendukung pariwisata berkelanjutan di DIY sangat besar, namun masih dibutuhkan beberapa strategi pengembangan. Title: The Potential Apllication of Blue Economy in Supporting Sustainable Tourism in The Coastal Areas of Yogyakarta ProvinceThe condition of coastal areas that are rich in potential is not directly proportional to the level of welfare of the people in coastal areas, and this also happens in the Yogyakarta Province (DIY). Tourism activities are one of the solutions to improve people’s welfare. However, on the other hand, developing marine tourism activities in the DIY coastal area still faces various environmental problems. One concept that can be applied to address problems in coastal areas is the blue economy or Blue Economy (BE), namely the sustainable use of marine resources to improve people’s welfare by optimizing sustainable tourism. This study analyzed the potential for applying BE and strategies for developing sustainable tourism in the DIY coastal area. This research was carried out over five months, from January to May 2023. Data collection used literature reviews and interviews with the Maritime Affairs and Fisheries Service, Bappeda and the DIY Tourism Office. The data is then analyzed using BE implementation indicators. The development strategy is analyzed using the Strengths, Weaknesses, Opportunities and Threats (SWOT) matrix. The analysis results show that the potential for implementing the blue economy in supporting sustainable tourism in DIY is excellent, but several development strategies are still needed.

Published: January 2024

Allergic contact dermatitis (ACD) is a more frequent pathology in adults than in children, because, in most cases, allergic sensitization requires a prolonged exposure time to the allergen, mostly months or years. In fact, the actual incidence and prevalence of ACD in children and adolescents is unknown. However, there is a hypothesis that ACD is increasing in the pediatric population. Among the allergens involved in ACD, the frequency of paraphenylenediamine (PPDA) is increasing. PPDA is one of the five most common contact allergens in the general population and one of the 10 most common contact allergens in children. The most relevant sources today are henna tattoos and hair dyes. Currently, European Union legislation limits the use of PPDA in hair dyes and prohibits its use in henna tattoos. Despite this legislation, the use of henna tattoos with PPDA is becoming more frequent in younger ages. We report an early presentation of ACD by PPDA, with a permanent hypopigmented skin area as an aftermath, in a 7-year-old male child. We believe that health authorities should advise against making these tattoos in children.

A Gramaticografia latina no Brasil é um dos temas de interesse da disciplina de Historiografia da Linguística (HL), em nosso contexto nacional. Em nosso texto, debateremos aspectos teórico-metodológicos, acerca da constituição de uma narrativa historiográfica sobre a história da gramática latina no Brasil, pelo modelo “koerniano”, desenvolvido por Konrad Koerner (2014) e Pierre Swiggers (2013; 2019). Como modelo exemplar, para uma narrativa (meta)historiográfica da história da gramática latina no Brasil, temos também a recente publicação de Ricardo Cavaliere (UFF/ABL), sobre a história da gramática no Brasil (CAVALIERE, 2022), que pode nos servir de modelo à aplicação da historiografia “koerniana”, para uma análise de nosso contexto específico. O tema da história da gramática latina no Brasil foi abordado de forma precursora pelo latinista e filólogo Ernesto Faria (1906-1962), em duas de suas principais obras: a Gramática Superior da Língua Latina (FARIA, 1958) e Introdução à didática do Latim (FARIA, 1959).

Weather-related fragility modelling of critical infrastructure: a power and railway case study
Authors: Jia Zixuan , Donaldson Daniel L , Ferranti Emma
Published: January 2024

Climate change has led to more frequent and severe extreme weather events, which impact critical infrastructure networks such as railway and power systems. Although infrastructure networks are interdependent, the analysis to understand the impact of weather events on infrastructure systems is usually performed in sector-specific silos. A methodology to examine how the same weather events affect different infrastructure sectors is presented, in order to understand cross-sectoral impact of extreme weather for interconnected regional infrastructure. Fragility modelling was used to examine the impact of temperature and rainfall on power and rail system failures using the West Midlands (in the UK) as a case study. The results demonstrated that the impact of temperature was broadly consistent across both infrastructure networks, showing less impact until specific upper and lower thresholds are passed; these thresholds were found to be similar for the different infrastructure networks evaluated, but railway infrastructure was found to be impacted more by lower temperatures. A growing correlation between the number of faults on power and railway systems was also found for both rainfall and temperature, indicating the value in coordinating preparation and planning efforts. For infrastructure operators and owners, regional resilience forums and other decision makers, this study provides an approach to assess the regional impact of extreme weather across multiple infrastructure sectors. The results give useful insights to inform the allocation of resources in response to extreme weather events.
Analysis of floating photovoltaic systems on hydro reservoirs
Authors: Mamatha G , Kulkarni P S
Published: January 2024

Floating solar photovoltaic (FSPV) systems offer a more sustainable energy option than ground-mounted ones by avoiding land use and enabling decentralised power generation. This paper presents a conceptual hybrid design for an actual hydropower plant and a simulated FSPV plant, considering relevant factors. Five significant reservoir dams in India were chosen to test the proposed design, and as a novelty, the cooling effect was considered. In general, the cooling impact is dependent on the kind of supporting structure. Metrics such as generation, carbon dioxide (CO2) reductions, water savings and extra hydropower were computed in this work by considering two kinds of floating structures. The results indicate that with a total coverage of less than 20%, the hydroelectric reservoirs can double their installed power capacity. In terms of energy gain, the hydroelectric plant generated 92% more energy on average after integrating floating solar power. Furthermore, the capacity factor of the plant grew by an average of 18.43%. The total water savings in this scenario are 134.6 million m3, resulting in an additional 34.97 GWh of annual hydroelectricity generation. The cost–benefit analysis shows that the energy produced by FSPV is the most cost effective, ranging from 2.65 to 3.05 Indian rupees/kWh (US$0.03–0.04/kWh), depending on the FSPV platform.

Az ujjnyomatok az ember minden ujjhegyén látható jellegzetes bőrbarázdák, melyek mintázata minden embernél más és más. Amikor egy ujjhegy egy bizonyos felületet érint, időleges lenyomatot hagyhat a felületen. Ez a megfigyelés, párosulva az ujjlenyomat egyediségének felfedezésével, hozta létre azt az eljárást, melyet az elmúlt száz évben a legkülönfélébb területeken alkalmaztak. A technika elterjedését elsősorban az motiválta, hogy a késő 19. század bürokratizálódó államai arra törekedtek, hogy az egyéneket immár ne pusztán nevük, hanem fizikai tulajdonságaik alapján azonosítsák. Az ujjlenyomatvétel egyénekhez rendelhető technikájával – hogy csak a legfontosabb alkalmazását említsük – az állam egy rendszerezett bűnügyi nyilvántartást dolgozhatott ki. Ezzel veszi kezdetét az ujjlenyomat általi azonosítás modern története.

Amaç: Bu in vitro çalışmanın amacı, universal adeziv sistemin farklı uygulama yöntemlerinin sınıf V akışkan kompozit restosyonların kenar mikrosızıntısı üzerine etkilerinin değerlendirilmesidir.
Gereç ve Yöntem: Bu çalışmada, toplam 60 adet sağlam premolar diş kullanıldı. Dişlerin bukkal yüzeylerine, servikal kenarı dentinde ve okluzal kenarı minede olacak şekilde standardize edilmiş Sınıf V kaviteler (3 mm x 3 mm x 1.5 mm) hazırlandı. Örnekler, kompozit rezin tipi (Filtek Z250/FZ, Metafil Bulk Fill/MB ve Nova Compo HF/NC) ve universal adezivin uygulama yöntemlerine göre (selektif etch/SEE ve self-etch/SE) rastgele 6 gruba ayrıldı: Grup FZ+SEE, Grup FZ+SE, Grup MB+SEE, Grup MB+SE, Grup NC+SEE, Grup NC+SE. Örnekler, 24 saat 37° C’de distile su içerisinde bekletildi ve 10.000 döngüde termal siklusa tabi tutuldu. Ardından, %0.5 metilen mavisi solüsyonunda 24 saat süresince bekletildi. Mikrosızıntı tespiti için, stereomikroskop altında (40x büyütme) incelendi. Verilerin istatistiksel analizinde, Kruskal Wallis ve Mann-Whitney U testleri kullanıldı (p<0.05).
Bulgular: Okluzal kenarda, Grup MB+SE, Grup FZ+SE’ye göre ve Grup MB+SEE, Grup FZ+SEE’ye göre istatistiksel olarak daha düşük mikrosızıntı değeri gösterdi (p<0.05). Hem okluzal hem servikal kenarda, tüm restoratif materyaller için, uygulama yöntemleri arasında mikrosızıntı açısından anlamlı fark bulunmadı (p>0.05). Grup NC+SE hariç, diğer tüm gruplarda servikal kenarda okluzal kenara göre istatistiksel olarak daha fazla mikrosızıntı değeri gözlendi (p<0.05).
Sonuç: Universal adeziv sistemin her iki uygulama yöntemi kullanılarak elde edilen Sınıf V akışkan bulk-fill kompozit rezin restorasyonların, okluzal kenardaki mikrosızıntı performansının mikrohibrit kompozit rezinlere göre daha iyi olduğu tespit edilmiştir.
Manejo Sustentável da Produção de Café no Cerrado Mineiro: A Contribuição do Caulim para Cultivos Comerciais

A cultura do café ocupa um papel de destaque no contexto nacional, cabendo destacar que o plantio de café a pleno sol no Brasil teve seu início a partir da libertação dos escravos com a redução de mão de obra a custo baixo. De maneira geral, o grau de luminosidade é o principal fator responsável pela produção do cafeeiro pois afeta as gemas vegetativas e florais, que posteriormente se tornam os frutos. Existem manejos que possibilitam mitigar as perdas de produtividade causadas pelas adversidades climáticas, especificamente o aumento da temperatura do ar e o excesso de radiação solar. Neste contexto o presente trabalho teve por objetivo discutir a aplicação de caulim em cultivos comerciais de café junto a produtores rurais no cerrado mineiro, como uma pratica sustentável de produção agrícola. Para isso foi realizada uma pesquisa de campo junto a dezesseis cafeicultores que cultivam o café arábica (Coffea arabica L.), a pleno sol, no bioma do Cerrado de Minas Gerais, e que pulverizam o mineral caulim durante o manejo de produção das lavouras. Pode-se observar que os agricultores entrevistados buscam entender e aplicar algum tipo de manejo sustentável para a cultura e que a maioria vê a aplicação de caulim de maneira positiva, sendo necessário, porém implantar projetos de educação ambiental que tratem melhor desse tema junto aos cafeicultores de modo geral.

Authors: Pereira Isabela Oliveira , Bezerra Maria do Carmo de Lima
Published: January 2024

O artigo realiza um estudo sobre a regulamentação urbana voltada a definir a qualidade de espaços públicos urbanos para promover a qualidade de vida urbana. O instrumento urbanístico analisado é a lei de parcelamento do solo urbano e suas várias alterações ocorridas ao longo dos anos, desde 1979. Se concentra para análise nas alterações recentes procedidas pela Lei n° 13.465/17, que introduz as modalidades de parcelamento: loteamento com acesso controlado e condomínio de lotes, referentes à gestão do espaço público por agentes privados. O objetivo é avaliar se os requisitos urbanísticos exigidos a nível local para essas modalidades de parcelamento têm contribuído para melhores espaços urbanos e para uma gestão que garanta as manutenções adequadas. Como método, se utiliza de uma análise comparativa da Lei n° 6.766/79 e das diversas alterações ocorridas, no que tange os requisitos urbanísticos para a constituição dos espaços públicos e para sua gestão, verificando o papel do governo federal e dos governos locais no tema. A partir dessa análise, realiza um estudo empírico do empreendimento ‘Cidade Urbitá’, a ser implantado em Brasília/DF, quanto à possibilidade de que resulte em espaços públicos dinâmicos. Como contribuição, destacam-se recomendações a serem adotadas pelos municípios quando da elaboração da regulamentação municipal em favor de espaços públicos promotores da vida urbana mais dinâmica.

A região do córrego da grama na cidade de Bauru-SP, sofre frequentemente com enchentes em épocas de chuva, dessa forma o presente artigo teve como objetivo elaborar análise crítica da área de estudo, como também projetar um parque urbano com o sistema de drenagem sustentável chamado “wetland” ou “jardins filtrantes", para prevenir as enchentes e tratar dessas águas de maneira natural. A criação desse parque também teve como objetivo trazer uma área de lazer para essa região predominantemente residencial e com poucas infraestruturas que atendam esses moradores. Dessa forma, pensando no parque como um local de grande importância para a cidade e população, esse trabalho se pautou em referências bibliográficas acerca da drenagem urbana, prevenção de enchentes e purificação de água, bem como na pesquisa de campo, por meio de visita in loco e coletas de dados que foram analisados para entender as potencialidades e fragilidades dessa área. Os resultados dessa pesquisa de extrema relevância social e de drenagem urbana para a região, e ainda para futuras intervenções na área.
Infraestrutura verde: Proposta conceitual para o Córrego Barra Bonita -SP
Authors: Nascimento Cristina de Jesus , Gulinelli Érica Lemos
Published: January 2024

A formação das cidades ao redor de córregos e rios é uma prática comum, porém, a falta de políticas públicas, planejamento e ocupação inadequada dessas áreas ribeirinhas geram diversos problemas. A ocupação desordenada nessas regiões resulta em riscos de enchentes, inundações e degradação ambiental. A falta de infraestrutura adequada de drenagem urbana e controle das águas pluviais agrava ainda mais esses problemas. Para mitigar essas questões, propõe-se a implementação de soluções como a infraestrutura verde, a fim de reduzir o escoamento superficial e aumentar a infiltração das águas pluviais. Essas medidas visam diminuir os problemas gerados e promover uma ocupação mais sustentável dessas áreas ribeirinhas. Nesta pesquisa, é fundamental realizar uma análise detalhada da área de intervenção, além de compreender brevemente a origem da cidade de Barra Bonita e sua relação com os corpos d'água locais, em especial o Córrego Barra Bonita. Para lidar com os problemas causados por enchentes e inundações, é necessário adotar soluções técnicas baseadas em infraestrutura verde. Assim, este estudo tem como objetivo propor intervenções projetuais que abordem os aspectos urbanísticos, arquitetônicos e paisagísticos em áreas que enfrentam graves problemas decorrentes da ocupação irregular e das inundações causadas pelas fortes chuvas.
