Authors: Shubhankar G. , Mittal A. , Panwar V. K. , Ghorai R. P.
Published: January 2025

Introduction. Bladder cancer ranks among the most prevalent malignancies worldwide, with non-muscle invasive bladder cancer (NMIBC) constituting most cases. Intravesical Bacillus Calmette-Guérin (BCG) therapy is a cornerstone in NMIBC management, reducing recurrence and progression rates. However, patient compliance remains a challenge due to adverse effects, discomfort, and the demanding treatment regimen.

   Objective. To evaluate the tolerability and complications associated with intravesical BCG therapy and to assess the efficacy of strategies implemented to enhance patient compliance and mitigate dropout rates.

   Materials & Methods. A retrospective analysis was conducted on 163 patients diagnosed with NMIBC who underwent intravesical BCG therapy at our institution from August 2018 to December 2022. Data included patient demographics, tumour stage, BCG dosage, therapy duration, and adverse effects. Compliance strategies involved dedicated outpatient clinics, exclusive resident and nursing staff, and proactive toxicity management. Dosage modulation to 80 mg was employed for patients unable to tolerate the standard 120 mg BCG dose.

   Results. Among the cohort, 86 % were male, with 63 % being chronic smokers. Recurrence occurred in 16 % of patients, with 4 progressing to muscle-invasive disease (T2). BCG-related toxicity (Grade 1) was observed in 50 % of patients, with conservative management proving effective. A dose reduction to 80 mg was necessary in 17 % of patients, improving tolerance in the majority. Key compliance strategies significantly reduced dropout rates, with 80 % of patients completing the full course of therapy.

   Conclusion. Strategic interventions such as dosage modulation, dedicated clinic days, and comprehensive patient counselling markedly improved adherence to intravesical BCG therapy, reducing adverse effects and dropout rates. These findings underscore the importance of tailored strategies to enhance compliance, ultimately improving NMIBC management and patient outcomes.

Authors: Das Jitu Mani , Behere Isha , Upadhyay Jnanendra , Borah Rajiv , Ingavle Ganesh
Published: January 2025

Regenerating injured nerves is difficult because they have little spontaneous regeneration potential. Advances in tissue engineering and regenerative medicine have emphasized the possibility of biomaterial-based methods for nerve healing. Natural protein-based biomaterials have benefits over synthetic ones, such as biocompatibility, non-immunogenicity, and biodegradability. Silk fibroin, generated from mulberry and non-mulberry silkworms, is especially promising because of its abundance, simplicity of processing into nerve-like structures, adjustable biodegradability, and mechanical robustness. Furthermore, non-mulberry silk fibroin contains the cell-affinitive RGD tripeptide, which enhances its ability to repair nerves. Studies using silk fibroin (SF)--based nerve conduits have demonstrated nerve regeneration rates of up to 80–90% compared to autografts, which remain the clinical gold standard. SF conduits exhibit outstanding mechanical properties, with tensile strengths up to 300 MPa and elastic moduli adjustable between kPa-MPa range, which closely mimic the native tissue and ensure durability in dynamic environments. This review explores the diverse types of silkworm silk fibroin (SSF) and their applications in biomaterial-based Peripheral Nerve Repair (PNR). It discusses the integration of SSF with other biopolymers and synthetic polymers, highlighting advancements in nerve guidance channels incorporating electro-conductive materials to enhance regeneration rates. The literature search was primarily conducted using the Web of Science database, employing relevant keyword combinations such as “silk fibroin + nerve repair,” “silk fibroin + peripheral nerve repair,” “silk + nerve repair,” and “silk + nerve repair + electrical stimulation.” As this review focuses on silkworm silk-based biomaterials, studies involving spider silk or recombinant silk-based biomaterials were excluded. The period considered began with the earliest relevant studies, with an emphasis on more recent advancements up to November 2024 to capture the latest developments in the field. Identified studies were categorized based on the biomaterial composition, including pure silk biomaterials, silk biopolymer binary composites, silk synthetic binary composites, and silk-hybrid composites. Key findings were synthesized to highlight the progress, challenges, and future directions in applying silk fibroin-based scaffolds and electrical stimulation technologies for nerve repair. The findings provide insights into the potential of SSF-based biomaterials and propose future directions for developing advanced nerve repair strategies.

Published: January 2025

BACKGROUND

Since the 1990s, the Veterans Health Administration (VHA) has maintained a system-wide digital database to provide integrated care for 9 million Veterans across 172 medical centers and 1,138 outpatient clinics in the United States.

OBJECTIVE

This paper highlights applications of VHA Big Data and the VHA Spinal Cord Injuries and Disorders Registry (VHA SCIDR) to precisely meet Veterans’ changing medical needs.

METHODS

The modernized VHA SCIDR uses a case-finding algorithm to extract data from Veterans’ electronic medical record (EMR). This data along with longitudinal data from other VHA sources yield robust models of population health to inform the development of cost-effective and targeted services for people living with Spinal Cord Injuries and Disorders (SCI/D).

RESULTS

Data from four VHA SCIDR data collection methods were consolidated to create a dataset of 73,947 living and deceased Veterans who received care from 1994 through 2022. As of January 2025, the modernized VHA SCIDR operational database includes 23,262 living Veterans who receive VHA SCI/D System of Care services.

CONCLUSIONS

Applications of VHA Big Data illustrate how biomedical informatics can improve the precision of care for people living with SCI/D. Synthetic datasets are one strategy VHA is using to develop and test data models and allow comparisons with non-Veteran data. VHA Big Data supports precision medicine with informatics, machine learning, and artificial intelligence tools that leverage a vast array of data to improve outcomes through the delivery of precise, seamless medical care.

Introduction. The article deals with names of dairy products used by peoples inhabiting the Ural-Volga Region. Goals. The study seeks to identify general (characteristic of the Ural-Volga peoples at large), genetic (characteristic of a specific language family — Turkic or Finno-Ugric), and areal (characteristic of a certain language area) features pertaining to origins, development and functioning of lexemes denoting dairy products. Our efforts involve the use of digital technologies in the study of material culture-related vocabulary, namely the LingvoDoc platform which makes it possible not only to upload, systemize, and store language data but also to conduct automated searches and analyses according to required options, including mapping of lexical materials. The fact names of dairy products in the Turkic and Finno-Ugric languages of the Ural-Volga Region have remained understudied never to enjoy any standardized description makes the work relevant enough. Materials and methods. The paper examines studies on ethnography of the Ural-Volga peoples, etymological, lexicological, lexicographical insights into the Turkic and Finno-Ugric languages. In terms of theory and methodology, the study rests on writings dealing with linguistic contacts across the specified region, as well as works discussing food and dairy vocabularies. The work employs a variety of research methods, including the comparative historical one and those of lexical semantic analysis and linguistic mapping. Results. It has been revealed that there are no original names ascending to common stems for dairy terms across the Turkic and Finno-Ugric languages of the Ural-Volga Region. However, in etymologies of names for milk, butter, cream some genetic features can still be traced: in Turkic languages, such names do stem from a common root that stands for milk and cream, while in Finno-Ugric languages — it is about the lexeme for butter. Terms for butter, ghee, and cottage cheese in all the examined languages tend to meet motivational characteristics. There are also some areal phenomena in designations of yogurt and cottage cheese (for example, these in Mari and Chuvash attest to certain affinities between the languages). Finally, original names for ayran and kumis are available only in Turkic languages, and only loanwords be observed in Finno-Ugric ones.

Published: January 2025

Lighter construction in the structure of transportation make industries rely on aluminium as construction materials and new technology of joining such as friction stir welding become increasingly applied. Since welding force in the process is considered high so that many researches are focussed on this area. In this research, a new method of welding by using non-rotating shoulder tool and combined with pre heating was investigated. The result give confirmation that the methods was proven to be adequate to produce sound welding when the parameters chosen was rightly. Eventhough the method was able to lower the force but significant results only observed for Fx while another force, i.e. Fz, did not have similar significant results. Non-rotating shoulder with additional heat input has limited capability in lowering forces in Fz because of its design, while has very good capability to lower Fx. Also, it was obvious that the heat source using propane torch was not adequate to give uniform additional heat input in all welding phase and still need another moee porent heat source in order to improve the performance.

Published: January 2025

The electric engine is a serious opponent of the fuel engine. However, this does not mean that fossil fuels should be abandoned, but rather makes it a great challenge and a strong reason to develop fossil fuels to be even more efficient. Increasing the combustion efficiency of the current fuel engine can be done in various ways and methods. One of the many ways to increase combustion efficiency in terms of fuel is by mixing the fuel with other compounds. This article examines the effect of mixing variations of methane gas with nitrogen gas. The flame propagation speed in the midpoint of the mixture of stoichiometry (methane-air) and Nitrogen (N2) on the top ignition is 2233.33 mm/s at N2 10% of the third frame and at lower ignition, the speed is 3550.03 mm/s at N2 20% of the second frame. In addition, the bottom ignition experiment has a very large effect on maximizing the speed of flame propagation, especially in the 20% N2 sample. Therefore, the highest improvement in combustion efficiency is obtained by using a 20% N2 mixture and at the bottom ignition condition.

Published: January 2025

Backward Facing Step(BFS) has been widely recognized for its application to turbulence fields in deep flow. The flow separation occurs due to a sudden change in geometry. To know the phenomenon of flow in BFS can be done with a numerical approach. In some cases, numerical studies have a weakness in the computational time aspect. This study focuses on the prediction of Cp and Cf on BFS flow using Machine Learning. It begins with a meshing sensitivity approach with the number of elements as much as 22188 cels in a numerical simulation with a step height of 12.7 mm. This numerical study will be carried out using Reynolds number in the turbulent region of Re 36000. The turbulent k-omega shear stress transport model was used to perform numerical simulations in the open-source software package OpenFOAM®. Simulation data in the form of speed and pressure at each node that represents the form of turbulence is used as a dataset in Machine Learning. Three Machine Learning models, namely Multi-Layer Perceptron, RandomForrest, and Multiple Linear Regression are used to predict Cp and Cf. The effectiveness of each of these models is -101.5% for Multi-Layer Perceptron, 96% for RandomForrest, and 99% for Multiple Linear Regression. With the best effectiveness value, the Machine Learning Multiple Linear Regression model is used to get the predicted Cp and Cf values ​​from variations in step height of 9.525 mm, 6.35 mm, and 3.175 mm. With these results, it shows that the Machine Learning model can be used to predict the BFS turbulence flow obtained from the results of the OpenFoam® numerical approach.

Published: January 2025

Mesoscale combustor is one of the components that serves to generate heat on a micro power generator. As one of the components of a micro power generator, meso scale combustor serves to supply heat through the combustion process. The stability of the flame in the combustion chamber meso scale combustor is influenced by the temperature of the combustion chamber. One way to maintain a high temperature in the combustion chamber is to insert a flue gas stainless steel mesh resistor.. This research aims to prove the role of flue gas mesh resistors in stabilizing the flame on the meso scale combustor... The heptane liquid fuel flame was successfully stabilized at an equivalence ratio of ɸ 0.81 – 1.29 and a reactant flow velocity of 26.12 – 36.83 cm/s. The higher the rate of reactant flow, the higher the flame temperature until it reaches 502ºC. Combustor with flue gas mesh resistor is 10 mm away has a flammability limit that is not wider than a combustor without flue gas mesh resistor.

Published: January 2025

Wire Electric Discharge Machine (EDM) is a non-conventional metal cutting machine. This machine is commonly used to form machine components that have complex shapes and require high precision. Not many conventional and non-conventional machines are capable of producing small module gears. The cutting groove occurs from the erosion of the electric spark by the electrode wire moving from the coil of wire and forming or cutting the workpiece. One of the machining parameters that determine the quality of the product on an EDM wire is Current. So this study aims to determine the deviation of the gear profile cutting groove and the roughness that occurs in the straight gear profile cutting groove from the results of the Wire EDM process. In this thesis research, the varied parameters are electric current. The current used is 6 A, 7 A, 8 A, 9 A 10 A. The results of this research show that the current 6 A has an average deviation value of 0.0228 mm. At current 7 A has an average deviation value of 0.0255 mm. At current 8 A has an average deviation value of 0.0275 mm. At current 9 A has an average deviation value of 0.0313 mm. And at a current of 10 A has an average deviation value of 0.0362 mm. At current 6 A has an average roughness value. At current 7 A has an average roughness value. At current 8 A has an average roughness value. At current 9 A has an average roughness value. And at current 10 A has an average roughness value. This is due to the greater use of an electric current at the electric voltage, which will cause the sparking to get bigger too, this causes the movement of the electron flow to hit the surface of the workpiece faster, resulting in an increase in temperature which results in erosion of the workpiece surface. , this will change the result of the cut which affects the size precision and roughness of the wire EDM.

Published: January 2025

Year by year, fossil fuels start to run out due to the increasing marketing of fuel due to the increasing number of vehicles in Indonesia. It is proven by the increase in fuel prices in Indonesia, which means that the available oil is running low. To overcome the excessive use of fossil waste, researchers use alternative materials which are recycled from waste or commonly called bioethanol. The purpose of making a fuel mixture is that in addition to materials that are easily available, bioethanol does not damage the surrounding environment because it uses materials that do not contain harmful substances, which can be recycled such as fruit peels or plant waste. The study method used is experimental, using a Yamaha Force 115cc motorcycle. Data is obtained directly by observing the analysis of experimental results and then concluding in the form of graphs and tables. This test uses a dynamometer to determine the power and torque produced, while for testing the rate of fuel consumption using a measuring burette, then the calculation of fuel consumption is carried out. The results showed that there were differences in power, torque, Bmep and fuel consumption produced by variations in fuel. For maximum power produced on E15 fuel of 6.47 hp and a maximum torque of 5.16 Nm. For the lowest power produced on E20 fuel of 5.67 hp and the lowest torque of 4.39 Nm. The lowest fuel consumption was found in the use of E10 fuel of 0.000338 kg/hP while the highest fuel consumption was produced by E20 fuel of 0.0000406 kg/hP. For the highest Bmep on E15 fuel of 11.91 Psi and the lowest on E20 fuel of 11.39 Psi.

Published: January 2025

This study investigates and identifies the effects produced by defect on an airfoil when compared to a smooth airfoil. The defect used in this research is of the surface concaved defect (SDD) type, with a deep defect characterized by a smooth sunken deformation. The opening size used is t*=12%, and the equivalent depth of the defect is h*=3%. Computational methods are being used in this research to analyzing flow of the fluid through the NACA 0015 airfoil, both in smooth and defective airfoil, with various Reynolds Number which are 1.6×106, 2×106, and 2.5×106. Standard k-epsilon model is being used in this research as turbulence model. For the smooth airfoil, stall conditions occur at an AoA of 11º, while for the defective airfoil, they occur at an AoA of 9^° for each Re variation. The average decrease in the Cl/Cd ratio from smooth airfoil to defective airfoil at each AoA for all Re variations is 33%. There is an increase in pressure on the upperside leading edge of defective airfoil for all Re values. Based on the velocity streamlines, vortices can be found at the defect cavity, and the vortex at the defective airfoil seems larger than the smooth airfoil.

Published: January 2025

Metal materials corrode because of an electrochemical process that damages or destroys them gradually. In addition to chemical reactions, high temperatures, mechanical operations, and rainfall exposure can all lead to corrosion. It is an experimental study with variation of voltage for AA 7075-T651. The voltage variation between 4 and 5 and 6 volts is the independent variable employed in this study. The rate of corrosion and the size of the pores are the dependent variables. One amp of current, thirty millimeters between the anode and cathode, one millimeter of sulfuric acid as the electrolyte concentration, and ten minutes of anodizing time are the controlled variables in this study. Variation in voltage throughout the anodizing process can regulate how quickly corrosion occurs via the oxide layer that is created. The 7075-T651 series aluminum alloy, when subjected to action anodizing at different voltages of 4 volts, 5 volts, and 6 volts, yields pore diameters measuring 0.273 μm, 0.436 μm, and 0.522 μm, respectively, according to SEM picture data.

The Contexts of Revelation: An In-Depth Study of Asbab Wurud Al-Hadith and Its Connection to Asbab Nuzul al-Quran
Authors: Sofyan Nur Baety
Published: January 2025

This study aims to provide a comprehensive interpretation of the concept of Asbab Wurud al-Hadith, contemporary scholars' views, its classifications, and its connection to Asbab Nuzul al-Quran. Employing a library research method with a descriptive-analytical approach, the research involves gathering data, presenting scholarly perspectives, analyzing, and exploring the relationship between Asbab Wurud al-Hadith and Asbab Nuzul al-Quran. The study begins by defining Asbab Wurud al-Hadith and presenting the perspectives of contemporary scholars, followed by classifying the types of Asbab Wurud al-Hadith that underlie the delivery of specific hadiths by Prophet Muhammad (SAW). It also examines the interconnectedness of Asbab Wurud al-Hadith and Asbab Nuzul al-Quran, demonstrating how they complement one another in fostering a deeper understanding of Allah's (SWT) revelations and the sayings of Prophet Muhammad (SAW). The findings of this study can be summarized into three key points: First, Asbab Wurud al-Hadith is a branch of hadith studies focusing on the reasons behind the emergence of a hadith, whether driven by events, circumstances, or inquiries during its delivery by Prophet Muhammad (SAW). Contemporary scholars generally agree on its significance, albeit with varying opinions on the underlying factors of particular hadiths. Second, Asbab Wurud al-Hadith is divided into two categories: hadiths associated with specific causes (Asbab Wurud) and those without identifiable causes. Third, there is a strong correlation between Asbab Wurud al-Hadith and Asbab Nuzul al-Quran, as both serve similar roles in clarifying meanings, reconciling or prioritizing differing interpretations (tarjih), and providing explanations for the causes and implications of revelations. Furthermore, each can serve as a context for understanding the other.

Banyak cara mendidik anak tanpa kekerasan yang telah penulis sebutkan berdasarkan hadist-hadist, jika harus memakai kekerasan maka ikuti kaidah-kaidah memukul, seperti cara mendidik yang telah dicontohkan rasulullah saw melalui hadis-hadisnya yaitu Anjuran mendidik anak dengan teguran baru di sertakan hukuman yang tidak menyiksa dan hanya cukup memberikan pemahaman jika perbuatan tersebut adalah salah, mendidik dengan kasih sayang dan perhatian kasih sayang bukan memanjakan anak namun yang dimaksud dengan kasih sayang adalah memenuhi kebutuhan jasmani dan rohani anak, sebaiknya orang tua tidak segan-segan memberi ciuman kepada anak, mendidik dengan teladan dan memakai kata-kata yang sopan dan lembut dalam menjelaskan suatu perihal kepada anaknya, seperti yang dicontoh Rasulullah.

This paper aims to reveal Sayid Utsman's arguments that Imkan al-ru’yat (the possibility of sighting the new moon) is at an altitude of 7 degrees. The study seeks to analyze Sayid Utsman's thoughts on Imkan al-ru’yat from a historiographical perspective. This includes exploring the intellectual genealogy of Sayid Utsman's astronomical thought, understanding his perspective on Imkan al-ru’yat, and examining the criteria for Imkan al-ru’yat during his era. The research relies on qualitative data collected through documentation methods to gain an in-depth understanding of Sayid Utsman bin Yahya's thoughts on Imkan al-ru’yat. It is found that, according to Sayid Utsman, Imkan al-ru’yat is at an altitude of 7 degrees under certain conditions, and sometimes even reaches 8 degrees. Sayid Utsman's thoughts on Imkan al-ru’yat are a result of his studies with his grandfather, Sheikh Abdurrahman bin Ahmad al-Misry. In establishing the 7-degree criterion, Sayid Utsman cites the opinions of Imam Ibn Qadhi and Imam Ibn Hajar. It should also be noted that the Imkan al-ru’yat criteria during Sayid Utsman's era and for a century afterwards were considered to be at an altitude of 7 degrees.
Islam and Disaster Risk Reduction: The Role of Local Religious Leaders in Transforming Communities in Gampong Deah Glumpang, Banda Aceh
Authors: Fatimahsyam Fatimahsyam
Published: January 2025

The traditional perspective that perceives disasters as acts of divine destiny underwent a critical transformation following the 2004 Indian Ocean earthquake and tsunami. This classical view, which rendered communities passive in the face of disaster risks, has been progressively replaced by a more proactive understanding. Religious scholars (ulama) have played a pivotal role in fostering this transformation, encouraging communities to adopt active, participatory, and organized approaches to disaster risk reduction (DRR). This qualitative field study, conducted in Gampong Deah Glumpang, Banda Aceh, investigates two primary aspects: the management approaches of DRR programs implemented in the village and their impact on enhancing the community’s understanding and participation in building disaster resilience two decades after the tsunami. The findings reveal that local religious leaders significantly influenced the community’s shift from perceiving disasters as unchangeable divine decrees to recognizing the importance of proactive mitigation efforts. Through religiously grounded narratives, these leaders mobilized the community to actively engage in DRR initiatives, including risk mapping, contingency planning, and environmental conservation, as facilitated by the Banda Aceh Disaster Management Agency (BPBD), the International Organization for Migration (IOM), and the Indonesian Red Cross (PMI). The integration of religious teachings with DRR frameworks proved effective in transforming perceptions, strengthening social cohesion, and fostering inclusivity, particularly for vulnerable groups.
ANÁLISE SOCIOESPACIAL DO BAIRRO CAMPO NOVO, ZONA SUL DE PORTO ALEGRE, RS, A PARTIR DE 2010: UM ESPAÇO EM TRANSFORMAÇÃO
Authors: Monteiro Limara , Rodrigues Soares Paulo Roberto
Published: January 2025

Este artigo é parte de um estudo maior que compõe uma tese de doutorado acerca de uma análise socioespacial a partir do olhar da Geografia de um dos bairros do município de Porto Alegre, RS, Brasil. O bairro em questão, Campo Novo, localizado na zona sul de Porto Alegre, vem passando por uma série de transformações socioespaciais motivadas por empreendimentos imobiliários, elementos que se apresentam como parte da paisagem e do cotidiano dos moradores. O objetivo do artigo é, ainda que breve, trazer alguns dos novos elementos que estarão presentes no cotidiano da comunidade, em um futuro próximo e através da Geografia apontar caminhos para compreender o fenômeno da produção urbana hoje. Observa-se, a partir do ano de 2010 (última atualização do Plano Diretor de Desenvolvimento Urbano e Ambiental), o aumento significativo de construções de condomínios fechados no bairro e em seu entorno. A Geografia, enquanto ciência que estuda o espaço e sua reprodução contribui para uma análise embasada, não somente nas transformações atuais, como nas possíveis mudanças que poderão ocorrer para a comunidade local.

Published: January 2025

Os mapas mentais permitem que os alunos se envolvam ativamente na construção do conhecimento, desenvolvendo suas habilidades de análise, síntese e pensamento crítico. O objetivo deste artigo será evidenciarmos como o uso dos mapas mentais como uma estratégia pedagógica no ensino de Geografia, pode potencializar a construção do pensamento espacial nos professores e alunos e, sobretudo, o papel da formação continuada na produção e recontextualização didática dos conhecimentos geográficos pelos professores. A discussão é resultado de uma pesquisa colaborativa com professores da educação básica dos anos iniciais, na qual os sujeitos da pesquisa tornaram-se pesquisadores de sua própria prática, investigando questões relevantes relacionadas ao ensino e aprendizagem. Os resultados indicaram que os mapas mentais são representações espaciais especialmente úteis para a construção do pensamento espacial, pois ajudam a desenvolver habilidades relacionadas à compreensão e análise de mapas, com destaque para a compreensão espacial; a visualização de padrões; a orientação espacial e a resolução de problemas. Em relação a formação continuada colaborativa, os professores têm acesso a novas perspectivas teóricas, recursos educacionais atualizados e estratégias de ensino inovadoras e também pode promover a reflexão crítica dos professores sobre sua própria prática, incentivando a busca por novas abordagens pedagógicas que valorizem a participação ativa dos alunos, o pensamento crítico, a interdisciplinaridade e a contextualização dos conteúdos geográficos.
CONTRIBUIÇÕES GEOGRÁFICAS PARA O APERFEIÇOAMENTO DO PROGRAMA BOLSA FAMÍLIA EM CIDADES GÊMEAS

O Programa Bolsa Família é política pública de inclusão social que condiciona o recebimento de auxílio financeiro pelos beneficiários cadastrados à um conjunto de exigências como: a frequência escolar, realização de exames pré-natais, atualização da cobertura vacinal, acompanhamento de condições de saúde na primeira infância. Essas condicionalidades exigem um espaço geográfico dotado de materialidades, como escolas, postos de saúde, condições para mobilidade urbana, entre outras. Apresentamos, neste texto, propostas para aperfeiçoamento desse programa enfocando as condições dos municípios de fronteira, com recorte particular para os municípios sul-matogrossenses Ponta Porã, Corumbá e Ladário. Os resultados foram obtidos a partir de trabalho de campo realizado nos anos de 2017 e 2018, dados secundários, revisão bibliográfica e conclusões das teses de Silveira (2019) e Kukiel (2022). O conhecimento do território é estratégico para o aperfeiçoamento das políticas, pois estas devem incorporar custos e estratégias de superação dos pontos de estrangulamento no acesso ao cumprimento das condicionalidades e a absorção da condição de fronteira como compartilhamento do cotidiano.

Estimativas da Organização das Nações Unidas (ONU) apontam para o aumento no movimento entre países ainda que inclua desafios potencialmente danosos à saúde mental de migrantes. Diante das fragilidades psicológicas e sociais de populações em deslocamento, realizou-se um estudo exploratório para avaliar o sofrimento mental através dos níveis de ansiedade e da ocorrência de Transtorno do Estresse Pós-Traumático (TEPT) em doze migrantes acolhidos na Casa do Migrante da cidade de Corumbá/MS. Aplicou-se um questionário sociodemográfico, as escalas GAD-7 e PCL-C, observação e entrevista clínicas. Os resultados indicam a presença de ansiedade moderada e grave e TEPT em 41,67% (n=5) dos participantes. Vivências de luto, rejeição, abandono, assassinato, conflito, ausência de recursos e privação foram relatadas em suas experiências de vida. Devido ao aumento da movimentação de indivíduos fugindo de conflitos, perseguições e dificuldades, é crucial o reconhecimento do impacto psicológico da experiência migratória para o delineamento de políticas públicas que aliviem esse sofrimento.

Neste estudo, apresentaremos a contextualização da migração japonesa para a Bolívia, em destaque a comunidade Nikkei que reside em Guayaramerín Beni/BO. A pesquisa trouxe enriquecimento intelectual, promovendo uma perspectiva de valor à cultura japonesa. Tivemos como objetivo conhecer a comunidade Nikkei e identificar as estratégias construídas pela comunidade para manter viva a cultura Japonesa, como: a língua, religião, costumes, danças, ritos dentre outras tradições. Observamos que a comunidade tem tentado preservar a cultura trazida por seus antepassados, enfrentando desafios para resgatar algumas tradições da cultura japonesa. Para este estudo buscamos desenvolver a pesquisa bibliográfica e a pesquisa de campo com base na metodologia do Estudo do Meio. Os resultados indicam dificuldades em manter e transmitir cultura ao decorrer das gerações, em especial a língua japonesa, principal elemento para o fortalecimento da identidade coletiva do grupo e dos laços culturais além de suas origens.
