The purpose of the article was to describe the agonistic behavior of the Baikal seal Pusa sibirica at the coastal rookery based on the analysis of video materials obtained during continuous fi lming over several seasons at one of the main coastal rookeries on Dolgiy Island (Ushkany Islands, Lake Baikal). The original ethogram of aggressive and pacifying behavior was compiled for the species, including 20 behavioral patterns. Visual patterns play a predominant role in agonistic relations of seals at coastal rookeries. Due to diverse pacifying patterns, the Baikal seal can gather in relatively numerous haul-outs (tens of individuals) in a limited space of coastal rookeries and coexist quite peacefully without causing signifi cant damage to each other, limited to rare minor injuries. Almost all agonistic interactions of seals on coastal rookeries are caused by competition for territory, a limited resource. The most common is front fl ipper swing and fl ipper hit (imitation and contact). The frequency of its use (48–64%) depends on the density and size of the substrate. Frequency of fi ghts in the water is up to 18%. Other commonly used pacifying patterns include tactile infl uences of varying intensity (up to 55%) and descent into the water or fl ight (8–18%).

The enormous infl uence of free-living populations of the domestic cat (Felis catus L., 1758) on the wild fauna of small animals throughout the world provides the basis for a careful multilateral study of such populations with a view to their subsequent control, including their genetic structure. A description of the genetic profi le of the free-living population of domestic cats of Russky Island is given. It has been shown that the island population is genetically almost identical to the mainland population of Vladivostok. The exception is a statistically signifi cantly lower proportion of piebald cats on Russky Island (51.8 ± 4.8% versus 63.8 ± 2.0%, p < 0.02). This indicates a common origin for these populations. Due to their recent emergence (probably no more than 160 years ago) and low level of isolation, the populations experienced little genetic shift relative to each other. Similar data were obtained earlier for other pairs of settlements (urban- rural) in Primorsky Krai. A comparative analysis of the available data on the genetic diff erentiation of adjacent urban and rural populations of free-living domestic cats was carried out. The possible connection of genetic variability with the advantage in hunting activity of cats is discussed.

The authors give ecological arguments for the creation of the Teriberka Nature Park (2,418.5 ha). The Nature Park is characterized by high recreational potential as well as environmental significance. 18 species of plants and animals listed in the Red Data Book of the Murmansk Region, as well as five ones listed in the Red Data Book of the Russian Federation are recorded within the boundaries of the Natural Park. There are natural-territorial complexes of special aesthetic value here: the valley of the Teriberka River, the coast of the Barents Sea with a rugged coastline, beaches and sea terraces formed by large rounded boulders, Batareisky Waterfall, rocky hills and areas of shrub tundra, interspersed with small lakes, sheer cliffs with colonies sea birds, a number of historical and archaeological sites. Currently, the landscapes of lower reaches of the Teriberka River are experiencing a strong human impact. An important feature of the territory is easy transport accessibility for tourists. At present, the uncontrolled tourist flow is the most significant agent of the territory transformation, as a result of which landscapes with high aesthetic qualities begin to degrade. With the creation of a natural park, the intensity and coverage of human disturbances of landscapes will be reduced, and the existing aesthetic potential of landscapes will be used more efficiently. Land use planning has been developed in order to establish a differentiated regime of special protection. The nature protection areas are intended to preserve the environment in its natural state, and the recreational zone is intended to ensure and implement recreational activities and nature-educational tourism. In order to preserve the landscape and architectural unity of the village and the natural park, regulation has been introduced for the construction of new and reconstructed buildings in accordance with the historical environment.

Published: December 2023

This study aims to determine the ability of Pseudomonad fluorescens isolates Pf-122 and Pf-142 secondary metabolites against R. solanacearum pathogen in vitro and in vivo. The study used a two-factor factorial experiment with RAL design and the observed data were analyzed using the Least Significant Difference (LSD) of 5%. The first factor was the type of isolate of Pseudomonad fluorescens: P1 (Pf-122) and P2 (Pf-142). The second factor was the concentration of the secondary metabolites: K1 (10%), K2 (20%) and K3 (30%), so six treatments were done and repeated five times. The in vitro results indicated all treatments could weakly inhibit R. solanacearum development indicated by the small inhibition zone. This may be due to the presence of siderophore antibacterial compounds; pioverdin, pioluteorin, HCN and phenazine. This study observed the largest inhibition zone in P2K3 treatment (Pf-142, 30%). The in vivo antagonist test indicated that all treatments could suppress bacterial wilt disease. The disease index was 0% for 4 weeks of observation while it reached 57.33% in control.
In silico analysis of putative hemolysin proteins in the genome of Vibrio alginolyticus ATCC 17749 and their structure prediction
Authors: Vibhuti Raj Kamal , Kumar Yatin , Pramanik Avijit
Published: December 2023

Hemolysin is one of the major pathogenic factors for pathogenic bacteria. Hemolysin can break down erythrocytes (RBC) which is called hemolysis. Hemolysins act on the cell membrane of erythrocytes, resulting in pore formation in the membrane and liberating hemoglobin into the growing environment. Hemoglobin is used as an iron source by pathogenic bacteria with the help of a siderophore or is taken up via iron receptors present on the bacterial cell membrane. Despite the pore formation into erythrocytes, hemolysin or cytolysin has also the ability to pore formation in a broad range of the cells such as mast cells, neutrophils and polymorphonuclear cells. It also enhances virulence by causing tissue and cell damage. Hemolysin is associated with the pathogenesis of different Vibrio spp. that cause either wound infection or intestinal infection. V. cholerae and V. parahemolyticus are popularly known for intestinal infection whereas V. alginolyticus and V. vulnificus cause would infections. The genome of Vibrio alginolyticus ATCC 17749 was analyzed for the gene responsible for the biosynthesis of hemolysins. Its genome encodes for five hemolysins that might play an important role in hemolysis and pathogenesis. Physiological properties functional annotation and predicted structure will significantly increase the level of understanding of hemolysins of Vibrio alginolyticus ATCC 117749.

Eunicellane diterpenoids, containing a typical 6,10-bicycle, are bioactive compounds widely distributed in marine corals as well as rarely discovered in bacteria and plants, attracting the attention of scientists in the pharmaceutical field. The intrinsic macrocycle exhibits innate structural flexibility resulting in dynamic conformational changes. However, the intriguing mechanisms controlling flexibility remain unknown. To shed light on this, a genome mining-based discovery of a terpene synthase, MicA, that is responsible for the biosynthesis of a non-flexible eunicellane skeleton, was presented, enabling us to propose a feasible theory that configurations of bridging carbons and their adjacent double bond govern flexibility in eunicellane structures. Notably, isotopic labeling experiments, together with density functional theory calculations, revealed that bacteria-derived MicA follows the catalytic route mainly as coral-derived eunicellane synthase through consecutive 1,14-ring closure, two 1,2-hydride shifts, 1,10-cyclization, and final deprotonation. Furthermore, structural analysis of the artificial intelligence-based MicA model and mutational studies provided an insightful basis for the enzymatic mechanism, featuring a new 2E-configured eunicellane scaffold formation by mutant MicAV220A. Finally, parallel studies of all eunicellane synthases in nature discovered to date, including 2Z-GGPP incubations and DFT-based Boltzmann population computations, revealed that a trans-fused bicycle with a 2Z-configured alkene restricts conformational flexibility resulting in a non-flexible eunicellane skeleton. Our findings presented a new eunicellane synthase, providing new insights into the eunicellane formation and the theory governing flexibility among eunicellane skeletons.

Published: December 2023

Neural network potentials (NNPs) offer significant promise to bridge the gap be- tween the accuracy of quantum mechanics and the efficiency of molecular mechanics in molecular simulation. Most NNPs rely on the locality assumption that ensures the model’s transferability and scalability and thus lack the treatment of long-range inter- actions, which are essential for molecular systems in condensed phase. Here we present an integrated hybrid model, AMOEBA+NN, which combines the AMOEBA potential for the short- and long-range non-covalent atomic interactions and an NNP to capture the remaining local covalent contributions. The AMOEBA+NN model was trained on the conformational energy of ANI-1x dataset and tested on several external datasets ranging from small molecules to tetrapeptides.The hybrid model demonstrated sub- stantial improvements over the baseline models in term of accuracy as the molecule size increased, suggesting its potential as a next-generation approach for chemically accurate molecular simulations.

Published: December 2023

Oilcane — an oil-accumulating crop engineered from sugarcane — and microbial oil have the potential to improve renewable oil production and help meet the expected demand for bio-derived oleochemicals and fuels. To assess the potential synergies of processing both plant and microbial oils, the economic and environmental implications of integrating microbial oil production at oilcane and traditional sugarcane biorefineries were characterized. Due to decreased crop yields that lead to higher simulated feedstock prices and lower biorefinery capacities, current oilcane prototypes result in higher costs and carbon intensities than microbial oil from sugarcane. To inform oilcane feedstock development, the required biomass yields (as a function of oil content) for oilcane to achieve financial parity with sugarcane were calculated. At 10 dwt % oil, oilcane can sustain up to 29% less yield than sugarcane and still be more profitable in 95% of simulated scenarios. With microbial oil production from cane juice, achieving this target results in a minimum biodiesel selling price of 2.14 [1.58, 2.76] USD∙L-1 (presented as median [5th, 95th] percentiles), a carbon intensity of 0.519 [0.475, 0.565] kg·CO2e·L–1, and a total biodiesel yield of 2060 [1770, 2350] L·ha–1·y–1.
Host-Guest Systems for the SAMPL9 Blinded Prediction Challenge: Phenothiazine as a Privileged Scaffold for Binding to Cyclodextrins
Authors: Andrade Brenda , Chen Ashley , Gilson Michael K.
Published: December 2023

Model systems are widely used in biology and chemistry to gain insight into more complex systems. In the field of computational chemistry, researchers use host-guest systems, relatively simple exemplars of noncovalent binding, to train and test the computational methods used in drug discovery. Indeed, host-guest systems have been developed to support the community-wide blinded SAMPL prediction challenges for over a decade. While seeking new host-guest systems for the recent SAMPL9 binding prediction challenge, which is the focus of the present PCCP Themed Collection, we identified phenothiazine as a privileged scaffold for guests of β cyclodextrin (βCD) and its derivatives. Building on this observation, we used calorimetry and NMR spectroscopy to characterize the noncovalent association of native βCD and three methylated derivatives of βCD with five phenothiazine drugs. The strongest association observed, that of thioridazine and one of the methyl derivatives, exceeds the well-known high affinity of rimantidine with βCD. Intriguingly, however, methylation of βCD at the 3 position abolished detectible binding for all of the drugs studied. The dataset has a clear pattern of entropy-enthalpy compensation. The NMR data show that all of the drugs position at least one aromatic proton at the secondary face of the CD, and most also show evidence of deep penetration of the binding site. The results of this study were used in the SAMPL9 blinded binding affinity-prediction challenge, which are detailed in accompanying papers of the present Themed Collection. These data also open the phenothiazines and, potentially, chemically similar drugs, such as the tricyclic antidepressants, as relatively potent binders of βCD, setting the stage for future SAMPL challenge datasets and for possible applications as drug reversal agents.

Introduction: Air flow in full-face snorkel masks (FFSMs) should be unidirectional to prevent rebreathing of exhaled air. This study evaluated rebreathing and its consequences when using FFSMs compared to a conventional snorkel. Methods: In a dry environment 20 participants wore three types of snorkel equipment in random order: Subea Easybreath FFSM; QingSong 180-degree panoramic FFSM; and a Beuchat Spy conventional snorkel (with nose clip), in three conditions: rest in a chair; light; and moderate intensity exercise on a cycle ergometer. Peripheral oxygen saturation, partial pressure of carbon dioxide (PCO2) and oxygen (PO2) in the end tidal gas and FFSM eye-pockets, respiratory rate, minute ventilation, were measured continuously. Experiments were discontinued if oxygen saturation dropped below 85%, or if end-tidal CO2 exceeded 7.0 kPa. Results: Experimental runs with the FFSMs had to be discontinued more often after exceeding 7.0 kPa end-tidal CO2 compared to a conventional snorkel e.g., 18/40 (45%) versus 4/20 (20%) during light intensity exercise, and 9/22 (41%) versus 3/16 (19%) during moderate intensity exercise. Thirteen participants exhibited peripheral oxygen saturations below 95% (nine using FFSMs and four using the conventional snorkel) and five fell below 90% (four using FFSMs and one using the conventional snorkel). The PCO2 and PO2 in the eye-pockets of the FFSMs fluctuated and were significantly higher and lower respectively than in inspired gas, which indicated rebreathing in all FFSM wearers. Conclusions: Use of FFSMs may result in rebreathing due to non-unidirectional flow, leading to hypercapnia and hypoxaemia.

Introduction: Quantifying inert gas wash-out is crucial to understanding the pathophysiology of decompression sickness. In this study, we developed a portable closed-circuit device for measuring inert gas wash-out and validated its precision and accuracy both with and without human subjects. Methods: We developed an exhalate monitor with sensors for volume, temperature, water vapor and oxygen. Inert gas volume was extrapolated from these inputs using the ideal gas law. The device’s ability to detect volume differences while connected to a breathing machine was analysed by injecting a given gas volume eight times. One hundred and seventy-two coupled before-and-after measurements were then compared with a paired t-test. Drift in measured inert gas volume during unlabored breathing was evaluated in three subjects at rest using multilevel linear regression. A quasi-experimental cross-over study with the same subjects was conducted to evaluate the device’s ability to detect inert gas changes in relation to diving interventions and simulate power. Results: The difference between the injected volume (1,996 ml) and the device’s measured volume (1,986 ml) was -10 ml. The 95% confidence interval (CI) for the measured volume was 1,969 to 2,003 ml. Mean drift during a 43 min period of unlaboured breathing was -19 ml, (95% CI, -37 to -1). Our power simulation, based on a cross-over study design, determined a sample size of two subjects to detect a true mean difference of total inert gas wash-out volume of 100 ml. Conclusions: We present a portable device with acceptable precision and accuracy to measure inert gas wash-out differences that may be physiologically relevant in the pathophysiology of decompression sickness.

Introduction: Capnography aids assessment of the adequacy of mechanical patient ventilation. Physical and physiological changes in hyperbaric environments create ventilation challenges which make end-tidal carbon dioxide (ETCO2) measurement particularly important. However, obtaining accurate capnography in hyperbaric environments is widely considered difficult. This study investigated the EMMA capnograph for hyperbaric use. Methods: We compared the EMMA capnograph to sidestream capnography and the gold standard arterial carbon dioxide blood gas analysis in a hyperbaric chamber. In 12 resting subjects breathing air at 284 kPa, we recorded ETCO2 readings simultaneously derived from the EMMA and sidestream capnographs during two series of five breaths (total 24 measurements). An arterial blood gas sample was also taken simultaneously in five participants. Results: Across all measurements there was a difference of about 0.1 kPa between the EMMA and sidestream capnographs indicating a very slight over-estimation of ETCO2 by the EMMA capnograph, but fundamentally good agreement between the two end-tidal measurement methods. Compared to arterial blood gas pressure the non-significant difference was about 0.3 and 0.4 kPa for the EMMA and sidestream capnographs respectively. Conclusions: In this study, the EMMA capnograph performed equally to the sidestream capnograph when compared directly, and both capnography measures gave clinically acceptable estimates of arterial PCO2.
Comparative Analysis of Various Machine Learning and Deep Learning Approaches for Car Resale Price Prediction in the Turkish Market
Authors: UYSAL Fatih
Published: December 2023

With escalating environmental concerns worldwide, the shift towards second-hand car markets has emerged as an eco-friendly alternative to reduce the carbon footprint associated with manufacturing new vehicles. However, the lack of accurate and efficient price prediction mechanisms may impede the growth and efficiency of these markets. This study, focusing on the Turkish second-hand car market, contributes towards addressing this gap by introducing a unique, comprehensive dataset gathered from various online markets across Turkey, thereby offering a broad spectrum of data pertaining to different vehicle types, specifications, and resale conditions. The study employs both classical machine learning methods, specifically decision trees, and deep learning models to predict used car prices. This comparative analysis aims to assess the potential of these methods in improving the predictability and transparency of resale price determination. Despite the superior performance of decision tree models, the study found that deep learning techniques achieved comparable results, indicating their potential for further optimization and enhancement. The accurate prediction of resale prices could streamline the operations of second-hand car markets, increasing their appeal to potential buyers and sellers. This could, in turn, contribute to environmental sustainability by encouraging the usage of pre-owned vehicles, which can substantially reduce the demand for new cars and thereby lower the environmental impact associated with their production.

In this paper, we position ourselves as Indigenous educators, involved in the creative healing arts, through filmmaking and community-based therapy. We discuss through an ongoing conversation our decolonising approaches to teaching and education, with a view to upholding student well-being and creating ‘communities of care’ in the classroom. This approach includes integrating the natural world into the process, encompassing Indigenous worldview, values and relationality with Mother Earth.
Decolonising Management. Reflections of a Human Resource Practitioner from the Global South
Authors: Goh Patrick
Published: December 2023

This article takes a slight detour from this edition's theme – decolonising systemic practice – by suggesting that systemic practices can be used to decolonise dominant discourses, such as Western-centric management and its associated form of knowledge production. My views are voiced from an insider–outsider, intersectional positionality – a person from the Global South now working as a Human Resource Practitioner in the United Kingdom.
The article posits management and human resource management as Western in their cultural roots and neoliberal in their economic worldview and proposes that underlying assumptions embedded in these discourses have resulted in epistemic othering and subjugation on an international scale. It suggests that decolonising management could begin with making the paradigm shift from a diagnostic to a dialogical understanding of organising human systems. It holds up this epiphany as an example of embracing indigenous knowledge and practices. The article also suggests, through a case story, the use of a systemic practice known as Social GRACEs (Burnham, 1992), that systemic reflexivity and the re-constitution of language games are paramount for making such a paradigmatic shift to decolonised practice.
Towards anarchy?
Authors: Huhnen Mark
Published: December 2023

The theme of this edition on decolonisation inspired me to remember, rethink and reclaim my relationship with a philosophical and political idea and movement: anarchy and anarchism. Despite having tried to distance myself from this label in the past due to its negative connotations, I now move towards it and embrace it. Finding connections in my own history, I roughly outline anarchism’s history and some of the diversity of the ideas labelled as anarchist. I will explore how these ideas, particularly the concepts of ontological and political anarchism and the idea of assemblages of power, directly influence my therapy and leadership coaching practice. I believe that some ideas within anarchism align well with systemic theory and can be an inspiring companion in our processes of decolonising our practice.

The Makran coast of Pakistan in the Northern Arabian Sea is a region of high biodiversity yet remains relatively under-studied in terms of polychaete fauna. In this study, we presented detailed morphological and taxonomical analyses of two newly discovered species of Eunicidae polychaetes, Eunice indica and Lysidice ninetta, collected during low tide from the intertidal zone of two stations along the Makran coast: Shamal Bandar, Pasni dated 31st January 2022 and Taak Beach, Ormara, dated 31st January 2022. Before our study, only 12 species of Eunicidae were known to occur in Pakistan. The identification and description of E. indica and L. ninetta provide important information about the distribution and taxonomy of Eunicid polychaetes on the Makran coast. These findings emphasize the need for further investigations and highlight the potential for discovering additional species within the region.
DNA Damage in Fish Due to Pesticide Pollution
Authors: ERGENLER Ayşegül , TURAN Funda
Published: December 2023

Toxic contaminants, including pesticides, microplastics, and heavy metals, have a significant impact on aquatic life and other aquatic species. These pollutants come from anthropogenic sources such as crop growing, industrial operations, effluent, residential wastewater, and leaching, as well as environmental events like storms, floods, and seismic processes. Pesticides, particularly pesticides, have been shown to have detrimental effects on aquatic ecology, causing decreased growth, restricted larvae and embryo development, and dysfunction in primary organs like the gill, liver, kidney, and gonad. Genotoxicity from pesticide exposure raises safety concerns, as prolonged exposure can lead to oxidative stress, mutagenicity, and cellular apoptosis. Pesticide exposure can lead to elevated levels, even without measurable concentrations in biological matrices. The toxicity of pesticides directly affects aquatic life, leading to high mortality rates or the complete elimination of species that serve as their food source.To maintain the well-being of aquatic organisms, particularly fish, and protect aquatic ecosystems, it is crucial to investigate safe, acceptable, and efficient alternatives to pesticides. In this study, we focuses on the hematological, biochemical, and histopathological changes induced by pesticide exposure and highlights strategies for mitigating the adverse impacts of pesticides on fish. Further investigation is needed to determine species suitability for toxicity detection, an essential aspect of monitoring aquatic environments for agricultural pesticides.
Flexibilidad laboral y equidad de género en dos microempresas de Tamaulipas-México.
Authors: Lladó Lárraga Dora María
Published: December 2023

Ante los cambios que se vienen presentando en los modos de generación, producción, comercialización de los productos y servicios en el contexto mundial, se vienen modificando las condiciones de trabajo entre las diferentes organizaciones laborales. Una característica resultante de ello es la flexibilización laboral, mayormente representada en el mundo a partir de la década de los años noventa. El propósito del presente ensayo es presentar evidencia de condiciones de flexibilidad laboral entre los trabajadores de dos microempresas de Tamaulipas, una del ramo civil y otra del área ambiental. Para lograr este propósito se diseñó un estudio cualitativo y se consideró pertinente la aplicación de una entrevista a profundidad a los directivos y profesionistas de los dos casos seleccionados a fin de detectar las condiciones y características de los mercados laborales flexibles, a partir de sus opiniones sobre los mecanismos de inserción y sus condiciones de trabajo y, con ello, presentar algunas evidencias sobre la inequidad de género en el contexto de los mercados flexibles.
The Problem of Incredible Contracts for the Japanese Military Comfort Project during the Pacific War
Authors:   Institute of Korean Studies, y y , y y
Published: December 2023

Decades after the mobilization of comfort women from the late 1930s to 1945, disagreements over the issue continue to escalate, fueled by limited information and differing perspectives. This article aims to foster an academic consensus by employing a law and economics framework, contrasting with an opposing viewpoint. By examining the bilateral relationship between the Japanese authorities and comfort agents, previously overlooked aspects are brought to light. The analysis reveals varying levels of contractuality in different bilateral relationships, with comfort women lacking basic contractual requirements. However, the relationship between the Japanese authorities and comfort agents demonstrates greater fulfillment, albeit with an inherent imbalance. Notably, credible commitments between the authorities and agents, independent of written contracts, facilitate reciprocal agreements. Historical records shed light on this relationship, providing a basis for logical deduction. Resolving the current disagreements requires considering these perspectives, potentially alleviating longstanding antagonism and reconciling incompatible views surrounding the issue.
Personalization of Executive Power After COVID-19 Onset in South Korea
Authors:   Institute of Korean Studies, f f , f f
Published: December 2023

How has COVID-19 affected the personalization of executive power in South Korea? To answer this question, we draw on the conceptual framework of personalization concerning democracies and autocracies. We find that, personalization attempts were made via mechanism of personnel management (e.g., the appointment of allies within the pandemic-response bureaucracy) and via mechanism violence which consists of enacting the Infectious Diseases Control and Prevention Act, which restricted the freedom of assembly of anti-government forces. However, personnel management was more pronounced than the mechanism of violence due to the role of administrative courts and the National Human Rights Commission, which prevented an outright ban of freedom of assembly. Under the Park administration, many personalization attempts were made but not fully realized due to the fragmented command chain within the pandemic bureaucracy. We discuss the prospects of continued personalization under the Yoon administration via personnel management in the pandemic bureaucracy.

Este artigo aborda o problema da construção de conhecimento pelas práticas experimentais em Design Estratégico. Ele parte de uma compreensão em que vivemos em um tempo de crises cada vez mais complexas e potencializadas em redes que se desdobram infinitamente. Para tanto, vamos nos reportar aos trabalhos feitos ao longo de 3 anos com estudantes de Mestrado e Doutorado em Design, enfatizando suas atividades projetuais decorrente. Os resultados dessas práticas, envolvendo uma série de protótipos e projetos especulativos, foram todos publicados em um site/blog produzido para a disciplina de Experimentação em Design Estratégico da Unisinos. Os materiais publicados nesta plataforma digital nos alimentam a discussão sobre as seguintes questões: em tempos de crise e de sentir em rede, que argumentos teórico-práticos da Experimentação em Design Estratégico são revelados pelos projetos e protótipos produzidos e que manifestações de crítica à (in)sustentabilidade dos nossos modos de vida os projetos oferecem?
A reflection on seeds that have the ability to fly and are found in urban environments
Authors:   UFSC, Pazmino Ana Veronica
Published: December 2023

This article is a reflection on the seeds of two trees from the Atlantic Forest (ipê and paineira de praia) that have the ability to fly and are found in urban environments. The ability of seeds to be dispersed by wind, whether due to their shape (wings) or due to the characteristics of the material, are the result of a method of copying nature that depend on the constant interaction between the organism and the environment. Trees have developed an ingenuity to guarantee their perpetuation in the natural environment in stages of seeds, seedlings and young trees. Trees placed for urban afforestation or landscaping create problems with electrical wiring, cracks in the sidewalk and prevent the dispersion of seeds in the soil, being scattered on the asphalt. The trees mentioned in this article aim to ensure descent through the wind as a resource that is unused and wasted when placed in urban environments. The article presents the characteristics of the seeds and a particular action in the domestic environment to perpetuate the stages of seeds, seedlings and the possibility of becoming trees.

O artigo aborda o processo de cocriação entre designers e mulheres de uma comunidade quilombola e artesã, localizada no Maranhão. A partir do processo contemporâneo de design em criar narrativas situadas para a geração de autonomia em tais comunidades, relatamos uma pesquisa-ação realizada no intuito de produzir conhecimentos e significados localizados para parâmetros sobre superação da lacuna de gênero, estabelecidos em nível global pelo Fórum Econômico Mundial. Ao chegarmos perto da realidade do quilombo de Monge Belo, significados e imaginações de futuro emergiram a partir da cocriação de “coisas de design”. Com o Cofo de Histórias e livro das mulheres de Monge Belo, os quatro parâmetros para mensurar a lacuna de gênero, a saber, saúde e bem-estar, educação, participação econômica e empoderamento político, puderam ser tangibilizados a partir das narrativas locais
