Impact of Climate Change on Human Lactation: Biological, Socioeconomic, and Public Health Implications
Authors: Traylor Daryl O. , Cameron Winter , Clark Brianna , Anderson Eboni , Henderson Robert , Clark Lena
Published: September 2024

Global climate change poses significant challenges to human health and nutrition, particularly affecting lactating individuals and their infants. This review examines the impact of climate change on lactation, focusing on physiological, socioeconomic, and public health implications. Rising temperatures and heat stress can reduce milk production and alter milk composition, while malnutrition and water scarcity exacerbate these effects. Vulnerable populations face heightened risks, emphasizing the need for targeted mitigation strategies. Recommendations include enhancing nutritional support, securing water supplies, reducing environmental toxin exposure, and integrating lactation considerations into climate policies. Employing a social-ecological lens, this review underscores the necessity of a holistic approach to support lactating individuals in a warming world. Future research should explore the complex interactions between climate stressors and lactation to develop effective public health interventions.

Published: September 2024

An unprecedented surge in digital payments has had a profound effect on the economic development of developing nations. This transition has enabled greater financial inclusion through the provision of banking services to populations that were previously marginalised. In addition, it has reduced reliance on physical currency, thereby improving security and transparency. This bibliometric analysis examines the research on digital payments in Malaysia and Poland, providing a comparative perspective on research patterns and contributions in these two countries. Furthermore, this study offers a comprehensive examination of the research environment in Malaysia and Poland, elucidating the distinct approaches, methodology, and areas of emphasis in each nation. These findings provide useful insights for those interested in championing digital payment initiatives, as well as contributing to a more robust and resilient digital payment framework. As digital payment ecosystems mature, their significance in altering the economic landscape of emerging countries is likely to become more evident in facilitating cross-border knowledge exchange and collaboration.
Chemicals regulation and non-animal methods: displacing the gold standard
Authors: Carusi Annamaria
Published: September 2024

Regulating industrial chemicals in foodstuffs and consumer products is a major aspect of protecting populations against health risks. Non-animal testing methods are an essential part of the radical change to the framework for toxicity testing that is long overdue in global economies. This paper discusses reasons why the drive to reduce animal testing for chemical safety testing is so difficult to achieve, as perceived by those who are closely involved in chemicals regulations in different capacities. Progress is slow, despite the fact that the ethico-legal conditions for a move away from animal testing are largely in place, and despite scientific arguments for a radical change in the paradigm of toxicity testing, away from reliance on animal studies. I present empirical data drawn from two studies in a European Commission context promoting non-animal methods. The aim of the paper is modest. It is to foreground the voices of those who deal with the science and regulation of chemicals on a day-to-day basis, rather than to offer a theoretical framework for what I heard from them. I offer a synthesis of the main challenges faced by non-animal alternatives, as these are perceived by people in different stakeholder groups dealing with chemicals regulation. I show where there are pockets of agreement between different stakeholders, and where the main disagreements lie. In particular there is dispute and disagreement over what counts as validation of these alternative tests, and by implication of the traditional ‘gold standard’ of animal testing. Finally, I suggest that the shift to non-animal methods in chemicals regulation demonstrates the need for the concept of validation to be broadened from a purely techno-scientific definition, and be more explictly understood as a demand for trust and acceptance, with more attention given to the complex social, institutional and economic settings in which it operates.

Authors: Syalevi Rahmad , Raharjo Teguh , Wibowo Wahyu Setiawan
Published: September 2024

In today's dynamic environment, information technology (IT) stands as the cornerstone for organizational success and competitive advantage, with project management playing a crucial role in efficiently deploying IT resources. Recognized across diverse sectors like telecommunications, aerospace, and construction, Project Management Offices (PMOs) facilitate task organization and supervision, whether it is for IT product development, service improvement, system design, or implementing organizational changes. Despite extensive research on the positive impact of PMOs on organizational performance, a significant research gap exists due to the absence of a direct comparison between the influence of PMOs on IT and non-IT industries, indicating the necessity for further investigation in this domain. This study delves into the contribution of PMOs to organizational performance using the Competing Values Framework and evaluates five models and 17 performance metrics within the IT industry and across sectors. When comparing PMO performance, non-IT sectors precede interpersonal relationships, competency-based training, and workplace environment, whereas IT sectors emphasize the knowledge of PMO resource teams, efficient training, technology utilization, and collaboration for project success. Additionally, IT industries underline the role of technology in averting project management failures and prioritizing the punctual delivery of client requirements. These differences highlight the variations in PMO priorities between these industries, underscoring the significance of PMOs in enhancing organizational performance.
Envy-Free Division of Multilayered Cakes
Authors: Igarashi Ayumi , Meunier Frédéric
Published: September 2024

Dividing a multilayered cake under nonoverlapping constraints captures several scenarios (e.g., allocating multiple facilities over time where each agent can utilize at most one facility simultaneously). We establish the existence of an envy-free multidivision that is nonoverlapping and contiguous within each layer when the number of agents is a prime power, solving partially an open question by Hosseini et al. [Hosseini H, Igarashi A, Searns A (2020) Fair division of time: Multi-layered cake cutting. Proc. 29th Internat. Joint Conf. Artificial Intelligence (IJCAI), 182–188; Hosseini H, Igarashi A, Searns A (2020) Fair division of time: Multi-layered cake cutting. Preprint, submitted April 28, http://arxiv.org/abs/2004.13397 ]. Our approach follows an idea proposed by Jojić et al. [Jojić D, Panina G, Živaljević R (2021) Splitting necklaces, with constraints. SIAM J. Discrete Math. 35(2):1268–1286] for envy-free divisions, relying on a general fixed-point theorem. We further design a fully polynomial-time approximation scheme for the two-layer, three-agent case, with monotone preferences. All results are actually established for divisions among groups of almost the same size. In the one-layer, three-group case, our algorithm is able to deal with any predetermined sizes, still with monotone preferences. For three groups, this provides an algorithmic version of a recent theorem by Segal-Halevi and Suksompong [Segal-Halevi E, Suksompong W (2021) How to cut a cake fairly: A generalization to groups. Amer. Math. Monthly 128(1):79–83].

Objectives: This retrospective cohort study aims to evaluate the costs and advantages of the surgical phase of the surgery-first approach (SFA) versus the orthodontic-first approach (OFA). Methods: Orthognathic surgery has been described as having two concepts: an orthodontic-first approach and a surgery-first approach. However, there was no consensus on which group has the best cost effectiveness in the surgical treatment phase. In total, 70 patients were treated; half of the patients were treated via the SFA, and another half were treated via the OFA. The information collected included operation cost, operation time, total hospital cost, and length of hospitalization. Effectiveness was determined by quality of life, which was measured with the Orthognathic Quality of Life Questionnaire Thai Version (OQLQ) before and then 6 months after treatment. The cost effectiveness was assessed with an incremental cost effectiveness ratio (ICER) and an incremental time effectiveness ratio (ITER). Results: The results indicated the intervention cost and time of SFA were slightly higher but more effective than those of OFA. However, the operation cost (p=0.375), operation time (p=0.556), total hospital cost (p=0.363), and length of hospitalization (p=0.643) and OQLQ scores (p=0.344) of both groups were not significantly different. Conclusions: The intervention cost and time of SFA were slightly higher but more effective than those of OFA. Depending on the result of this study, SFA treatment planning was a good choice for orthognathic treatment.

Objectives: The purpose of this study was to compare the effectiveness and salivary levels of tumor necrosis factor-alpha (TNF-α) in patients with oral lichen planus (OLP) treated with topical clobetasol propionate (CP) and fluocinolone acetonide (FA). Methods: A total of 26 patients diagnosed with erosive-atrophic OLP were randomlydivided into 2 groups: the first group received CP 0.05%, and the other received FA 0.1%. Pain scores, clinical scores, and saliva samples from the patients were collected for analysis both prior to treatment initiation and after 4 weeks. Salivary TNF-α levels were evaluated using an immunology multiplex assay. The Wilcoxon signed-rank test and the Mann-Whitney U test were used for intra-group and inter-group comparisons, respectively. Results: Both treatments showed significant reductions in pain scores, clinical scores, and salivary TNF-α levels compared with the pre-treatment values (p<0.05). After 4 weeks of treatment, CP 0.05% demonstrated a greater reduction in clinical score compared with FA 0.1% (p<0.05). Conclusions: CP 0.05% and FA 0.1% effectively treat OLP. CP 0.05% demonstrated a quicker clinical score reduction than FA 0.1% over four weeks. Additionally, both steroids reduced salivary TNF-α levels, which could indicate the possibility of using diseaserelated biomarkers for monitoring.

Objectives: This study aimed to develop and validate the Oral Health Literacy Assessment for Thai Older Adults (OHLA-OA) tool. Methods: The study comprised two phases: tool development and data collection. The OHLA-OA consists of three sections: Reading Comprehension, Understanding Directions, and Self-evaluated OHL skills. A cross-sectional survey was conducted with 408 participants from four regions in Thailand. The average age of the participants was 66.8 years (SD=5.6). The descriptive analysis was performed to explore general information, and reliability and validity of OHLA-OA were tested using Kuder-Richardson Formula 20, Cronbach’s Alpha, correlation, and logistic regression analyses. Results: The OHLA-OA showed high reliability with a KR-20 coefficient of 0.79 and Cronbach’s Alpha of 0.85. Concurrent validity demonstrated significant correlations between OHLA-OA scores and variables such as age, income, self-assessed literacy ability, and dental service utilization. Convergent validity showed a significant correlation (r=0.319, p<0.001) between OHLA-OA and the Thai Rapid Estimate of Adult Literacy in Dentistry (Th-REALD). Predictive validity indicated that higher OHLA-OA scores were associated with better oral health outcomes, including fewer decayed teeth (r= -0.166, p=0.01) and more filled teeth (r=0.184, p<0.01). The study proposed cut-off scores for 3 levels: Inadequate, Sufficient, and Excellent OHL. Conclusions: The OHLA-OA tool demonstrated good psychometric properties, making it suitable for assessing oral health literacy among Thai older adults. It highlights the necessity of integrating literacy assessments into dental care and public health interventions to improve oral health outcomes in aging populations.

Alveolar ridge deficiency is an unavoidable sequela of tooth extraction and poses major clinical challenges when reconstruction is anticipated. Various surgical approaches have been proposed to address horizontal defects, with autogenous bone grafting considered the current benchmark. However, alternative methods, utilizing tissue engineering principles and bone substitutes, offer reduced patient morbidity. This report presents an alternative case of severe horizontal bone defect augmentation in the anterior maxilla using sticky bone in conjunction with platelet-rich fibrin (PRF), and a Ti-reinforced membrane. Histologic evidence of sticky, deproteinized bovine bone material (DBBM) mixed with PRF without the use of autogenous bone is reported.
Manualisation in child and family social work: a comparative study of Norway and Wales

Published: September 2024

The article examines the use of manuals in child and family social work in Wales and Norway and considers their application in the structuring context of New Public Management and evidence-based practice. It is based on findings from a comparative survey-based instrument distributed to social workers. The problem statement is: what are social workers’ attitudes to and experiences of manuals in professional practice? The key research foci are: ‘How often do you use manuals?’; ‘Why do you use manuals?’; and ‘To what degree do you think manuals are useful to ensure the quality of the work you perform?’ Both workforces use manuals, though more so in Norway than in Wales. This is related to the fact that there is direct and stronger pressure from governmental agencies in Norway than in Wales for provider organisations and workers to deploy manuals. The uptake of manuals in Wales appears to be prompted more by worker self-selection and/or imitation of their usage in cognate practice settings. Norwegian workers to a larger extent than those in Wales think that using manuals enhances the quality of work. We discuss possible conceptual, institutional and practitioner-based reasons for the varied relationship between manuals and their application and highlight under-researched areas.

Published: September 2024

A hyperspectral mid-infrared (MIR) microscope utilizing single-pixel imaging (SPI) technology is demonstrated. The system integrates a tunable (8.3 µm − 11.1 µm) MIR quantum cascade laser (QCL) and a modified micro-opto-electro-mechanical digital micromirror device (DMD) for spatial light modulation. As a part of the system’s design, diffraction on the DMD chip is experimentally analyzed. Based on this analysis, the first diffraction order was selected for an optimal optical configuration thus providing high modulation contrast, which is critical for SPI. The spatial resolution of the developed microscope was evaluated using a reflective resolution test target, which verified resolution well beyond 24.8 µm at 10.1 µm wavelength. Obtained spectra, which are limited in bandwidth (9.80 µm − 10.42 µm) due to aperture constraints, are validated by characterizing a 8 µm-thick polypropylene (PP) foil and identifying PP in a polymer multilayer microtome section. Fourier-transform infrared (FTIR) spectra were used for reference. The microscope showcases SPI’s potential for efficient chemical analysis, offering rapid hyperspectral IR imaging.
Dynamic range limitations of non-coherent continous-wave THz photomixing systems with broadband detectors
Authors: Ourednik Petr , Theiner Dominik , Picco Gabriele , Unterrainer Karl , Feiginov Michael
Published: September 2024

The dynamic range of non-coherent continuous-wave (CW) THz photomixing (PM) systems with broadband detectors can be significantly limited by various parasitic effects. Specifically, we examine the generation of parasitic (i) THz and (ii) IR radiation, and (iii) higher harmonics in CW THz PM emitters. (i) The parasitic broadband THz radiation, spanning from 100 to 250 GHz with a total output power of 20 nW, results from not perfectly clean laser spectra. As a result, for a frequency-flat Golay cell detector, the PM-system dynamic range is limited to 32.8 dB at 500 GHz, 26.7 dB at 1 THz, and 8.5 dB at 2.3 THz. In the case of detectors with a frequency-declining responsivity, the dynamic range can drop by ∼10 dB more. (ii) The IR radiation leaking from a PM emitter (≈20 μW) is sensitive to the PM emitter bias, which results in its modulation with an amplitude of about 1.3 μW, when a standard PM-emitter bias modulation is applied. The detected IR radiation could be confused for the THz signal. (iii) Parasitic generation of higher harmonics in PM systems can also limit the system’s dynamic range or create spectral artifacts. However, we show that the harmonics are low at least at ∼1 THz and above. Specifically, they are less than 400 pW for fundamental frequencies above 750 GHz, which is more than 43 dB below the power of the fundamental harmonic. The above-stated values were obtained for a commonly-used PIN-diode photomixer mounted on a Si lens and 1.5 μm distributed-feedback lasers. In general, suppression of these parasitic signals is crucial for non-coherent CW THz PM systems.

Published: September 2024

Windows are a major source of heat loss from buildings in cold climates. Developing coatings for windows that retain high visible transparency and strongly absorbs solar energy in the near infrared region can help reduce energy consumption and cost for indoor heating. Nanophotonic structures based on metasurface and metamaterials have shown great potential for such applications. Unfortunately, most of the designs proposed so far are difficult to fabricate or expensive. In this work, we report the experimental demonstration of a low-cost alternative based on Ni/SiO2/Ni multilayer structure. The device provides a large increase in temperature under solar illumination while retaining high visible transmission. Our optical and thermal measurements reveal that the performance of the device remains stable over a long period. The combination of low cost, ease of fabrication, good optical and thermal performance, and long-term stability makes it a promising design for passive heating of windows in cold climates.

Published: September 2024

The microstructured optical fibers (MOFs) fabrication process involves repetitive mapping of the drawing parameters, which is time-consuming, laborious and inefficient, and has become a fundamental obstacle restricting the current design of many MOFs with high excellent performances from being fabricated. This paper adopts a multi-objective particle swarm optimization (MOPSO) algorithm to optimize the drawing parameters inversely according to the target MOFs, to realize fast and precise fabrication. In addition, the quantitative relationship between the drawing parameters is investigated, and guiding suggestions are provided for adjusting the drawing parameters in the experimental fabrication. Ultimately, the MOPSO model is utilized to identify the required drawing parameters for the target MOFs, and an eight-tube node-less hollow core anti-resonant fiber (HC-ARF) is experimentally fabricated with a transmission loss of 0.2 dB/m at the wavelength of 1550 nm and a bending loss of 0.1 dB/m at a bending radius of 5 cm. This study provides an approach to the efficient fabrication of MOFs, accelerating the production of MOFs with novel structures and outstanding performance in a variety of applications.

To begin, by changing the variable, quasilinear equations are transformed into semilinear equations. The positive solutions to semilinear equations are then presented using the Mountain Pass Theorem for locally Lipschitz functionals and the Concentration-Compactness Principle. Finally, an inverse translation reveals the presence of positive solutions to the original quasilinear equations.

O estudo objetiva relacionar gênero com a distribuição geográfica e titulatória de membros filiados à Federação Internacional de Xadrez (FIDE). Tem caráter exploratório e documental, analisando o banco de dados primários desta instituição com enfoque relacional e multidimensional. Os resultados indicam um predomínio de 85% de homens frente a 15% de mulheres entre seus integrantes, com concentração de 41% no continente europeu. A outorga de títulos esportivos a jogadores e treinadores se distribuiu também hegemonicamente entre homens, com ínfimo aumento de mulheres em posições, entretanto, de menor hierarquia entre treinadores. Conclui-se por uma tônica de dominação masculina em todas relações analisadas, constituindo esta uma sólida regularidade com sequer exceções neste subcampo esportivo. Sugere-se que futuras pesquisas considerem outros aspectos para além da análise quantitativa, tais como os de ordem socioculturais das histórias de vida das pessoas que conformam tal hegemonia, interseccionando eixos outros de desigualdades sociais.

A técnica utilizada para organizar os dados foi a Análise de Conteúdo, e para análise dos mesmos nos debruçamos nos estudos decoloniais. Os resultados apontam a necessidade de formar os licenciandos em Pedagogia, pois desenvolverão à docência na educação infantil e nos anos iniciais em diferentes modalidades de ensino, para o trabalho com as relações Étnico-Raciais, e evidenciam que a decolonialidade fornece elementos que permitem a construção de uma pedagogia outra, que opera uma mudança de paradigma para reexaminar a história africana e afro-brasileira presente nos materiais didáticos e nas práticas docentes.
ENREDO DA FEMINIZAÇÃO DO MAGISTÉRIO
Authors: Silva dos Santos Mayra
Published: September 2024

A finalidade deste trabalho é discutir sobre o ingresso, permanência e atuação de mulheres professoras nos primeiros anos de escolarização no Brasil, a partir do processo conhecido como feminização do magistério. O estudo foi realizado a partir de uma revisão bibliográfica, utilizando autoras clássicas dos estudos de gênero como Judith Butler (2003) e Joan Scott (2017); e autoras como Guacira Lopes Louro (1997), Jane Soares de Almeida (1998) e Ana Carla Menezes de Oliveira (2017) que versam sobre mulheres e docência. Atribuímos a inclusão de mulheres à expansão da escolarização, aliado a fatores econômicos, políticos e culturais da época, principalmente ligada à ideia de que a mulher teria capacidade natural de cuidar e ensinar. Contudo, compreendemos, que a construção de representações e estereótipos envolvendo a composição desse grupo profissional demarca uma lógica patriarcal das relações de poder comumente estabelecidas entre homens e mulheres.

A questão das diferenças vem apresentando cada vez mais visibilidade e se manifesta de diversas formas, desde questões étnicas, de gênero, de raça, orientação sexual, classe social, religiosas, entre outras. Dentro deste contexto, este estudo buscou compreender como as questões relacionadas às diferenças culturais são tratadas por professores/as de Educação Física e alunos/as do ensino médio de uma escola pública do Rio de Janeiro. Para tanto, foram realizadas entrevistas e observações das aulas ao longo de um semestre. Compreendemos que, embora as diferenças culturais estejam presentes na escola investigada, é grande a dificuldade por parte dos/as professores/as em lidar positivamente com elas.
VIA CRUCIS DO MENOR OU UMA POLÍTICA DO LUTO
Authors: Dos Santos Costa Júnior José
Published: September 2024

As 15 estações do calvário de Jesus Cristo foram apropriadas pela Campanha da Fraternidade (CF) na quaresma de 1987 para tornar visível o problema do jovem marginalizado. Partindo de um arquivo textual e audiovisual, problematiza-se: como, ao constituir imageticamente o sujeito infantojuvenil vulnerabilizado, a CF fez usos do passado e operou uma política do luto sobre as vidas juvenis perdidas para a violência nos anos 1970/1980? A partir da crítica pós-estruturalista de Foucault e Butler o texto problematiza as condições de emergência da CF em três enfoques: analisa os usos do passado na interface entre os rostos de Cristo e do menor; cartografa as ações das Comunidades Eclesiais de Base (CEBs); descreve as formas de participação infantojuvenil como políticas de subjetivação. Em termos metodológicos, opera-se com as ferramentas da arqueologia e da genealogia de Michel Foucault para descrever as materialidades enunciativas e as disputas na ordem do saber-poder por certa concepção do que era o jovem marginalizado, abrindo o caminho para uma crítica da subjetividade com a ótica pós-estruturalista de Foucault e Butler sobre os processos de sujeição. Conclui-se sobre a singularidade da luta por direitos humanos no início da redemocratização e as tensões operadas na configuração de um novo “sujeito de direitos”.

O presente artigo propõe uma análise do consumo literário na categoria Jovens e Adolescentes da Amazon, buscando compreender as relações entre as tendências de compra e as perspectivas sociais e identitárias em uma escala macro através de uma observação do ranking dos títulos mais vendidos na divisão. Para tal, nos apoiamos na netnografia como metodologia, através dos estudos de Robert V. Kozinets (2014), examinando a relação entre as obras mais populares e questões sociais como gênero, identificação pessoal e consumo por influência no ambiente digital. Os resultados revelam tendências como a ascensão de obras de autodesenvolvimento e espiritualidade, a intervenção do marketing de influência nas comunidades virtuais e a emergência de novas formas de publicação, como a autopublicação. A análise sob a perspectiva da interseccionalidade também destaca desafios como a falta de representatividade LGBTQIAPN+ e a persistência de padrões hegemônicos no mercado literário.
(DES)SEXUALIZANDO

Published: September 2024

Este artigo trata da descodificação dos códigos culturais de compulsoriedade, remetida à sexualidade de jovens, a partir da concepção deleuze-guattariana de agenciamento. Analisa o agenciamento juvenil da (des)sexualidade e investiga as capacidades de afetar e serem afetados de alunos da iniciação científica do ensino médio (IC-EM). O campo foi realizado em três escolas públicas de uma cidade do interior paulista, acompanhadas longitudinalmente por quatro anos e meio, como parte de uma pesquisa participante. Estes jovens puderam abordar o assédio, as violências morais e sexuais, gravidez, infecções sexualmente transmissíveis, e questões de saúde mental associadas a esses temas. A pesquisa possibilitou a ampliação do leque de enunciações sobre a sexualidade, que incluiu a prevenção do abuso e o uso do prazer em seus próprios agenciamentos maquínicos. O espaço protegido da pesquisa pode fortalecer o clima amistoso e propiciou que as capacidades de afetar e serem afetados dos IC-EM se intensificassem.
JUVENTUDES, RELAÇÕES ETNICO-RACIAIS E DE GÊNERO
Authors: Gonçalves da Silva Adriano , Tavares Marie Luce
Published: September 2024

O objetivo deste estudo foi problematizar as relações étnico-raciais e de gênero nos currículos de educação física, a partir das experiências de jovens estudantes do ensino técnico de nível médio no CEFET-MG. Um questionário foi aplicado a 157 estudantes com idade entre 15 e 18 anos. De forma geral, ainda que muitas/os estudantes tenham experiências positivas com a educação física, os relatos sobre as vivências do ensino fundamental apontam que a unidade curricular não tem sido um momento agradável para todas/os. A preservação dos estereótipos e opressões de gênero e do racismo estrutural indicam que é necessário que a educação física reconheça o lugar da diversidade em sua composição, investindo em práticas inclusivas e democráticas. Uma educação física que traz para seu cerne a diversidade cultural, social, étnica e de gênero constrói um caminho para que as/os jovens possam refletir a relação com seus corpos livres dos estereótipos.
SENTIDOS DAS JUVENTUDES E MASCULINIDADES NEGRAS NA CONTEMPORANEIDADE
Authors: Cruz Borges Luis Paulo
Published: September 2024

O presente trabalho faz parte de uma pesquisa já concluída (2019-2023) e tem como objetivo geral problematizar os sentidos das juventudes na contemporaneidade, em sua relação interseccional, a partir das dimensões de gênero, sexualidade, raça/cor e território, com foco nas masculinidades. Opera-se com as vozes de jovens negros, estudantes do 1º ano do Ensino Médio, de duas escolas públicas no estado do Rio de Janeiro. Pauta-se, metodologicamente em uma abordagem socioantropológica da educação, utilizando-se dos inventários do saber como forma de apreensão da realidade social. A interseccionalidade é a chave-analítica de compreensão indicando os sentidos de escola e conhecimento que hão de existir. À guisa de conclusão, afirma-se que a perspectiva interseccional avança no debate sobre as desigualdades educacionais e raciais, sinalizando possibilidades de uma educação emancipatória e antirracista.
Positional accuracy of cadastral maps digitized from the stable cadastre system
Authors: Tauchman Martin , Janata Tomáš
Published: September 2024

The accuracy of positional data in cadastral mapping is crucial for various technical activities within the cadastre and related decision-making processes. With digital maps becoming ubiquitous in cadastral operations, assessing the positional accuracy of cadastral maps digitized from stable cadastre systems has become essential. These maps, categorized as DKM and KMD, present different challenges in determining their overall positional accuracy. While DKM maps offer high accuracy, KMD maps, derived from stable cadastre systems, pose challenges due to their varied origins, including potential positional errors inherited from historical data.
This study proposes a methodology for assessing the positional accuracy of KMD maps by comparing digitized boundaries with actual field measurements. The evaluation considers factors such as cadastral area characteristics, available survey data, and the timing of digitization efforts. The study aims to categorize objects based on their positional accuracy by analysing shifts in boundary points and building positions.
Results from testing in selected cadastral areas reveal varying degrees of accuracy in KMD maps. While some areas demonstrate high accuracy, others exhibit significant positional inaccuracies, particularly in peripheral regions or linear parcels. The study suggests that areas outside municipal boundaries may require immediate remapping to ensure accuracy.
Overall, the findings highlight the importance of assessing and improving the positional accuracy of cadastral maps to enhance their utility in land management and decision-making processes. Further research in this area could focus on developing automated methods for detecting and correcting positional errors in digital cadastral maps.
RESEARCH ON OPTIMIZATION OF MOTORWAY ROUTE DESIGN SCHEME IN MOUNTAIN AREAS BASED ON ENTROPY WEIGHT-TOPSIS MODEL

During the design process of a new mountainous motorways, multiple route schemes are often proposed for a comprehensive design effort. Each route scheme will have its advantages and disadvantages, so it is often difficult to choose a route scheme. Usually the expert decision method is used to screen the route schemes, but this method mainly relies on the personal experience of experts, and it is difficult to measure the criteria, which can lead to the embarrassing situation that different experts do not agree on the choice of routes.In order to optimize the route scheme for the design process of mountainous motorways and improve the efficiency and scientificity of route scheme selection, evaluation indicators were selected from traffic safety, construction economy, and environmental friendliness. The Entropy Weight Method (EWM) was used to assign the weight of the evaluation indicators. By improving the Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS), the problem of subjective opinions and excessive reliance on objective data by designers in the multi factor evaluation process was overcome. A EWM-TOPSIS evaluation model was proposed. By analyzing specific examples of mountainous motorway construction, research results were obtained. The results indicate that the model can reflect the designer's intention towards the route scheme and the actual construction project. There is a high degree of consistency with the expert's empirical judgment, which verifies the feasibility and accuracy of the model. This model can provide reliable reference and basis for the decision-making of motorway route schemes in mountainous areas.
