Authors: Masudin Ilyas , Sumah Bangalie , Zulfikarijah Fien , Restuputri Dian Palupi
Published: August 2020

This chapter examined how the use of technology in inventory control impacts organizational performance since inventory is the most valued asset of an organization. From the summary of this study, it can be concluded that the adoption of technology as RFID in inventory management leads to improve the organizational performance in both financial and customer responsiveness. In the business performance, RFID could improve the organizational performance in terms of reducing inventory carrying costs on the warehouse, such as lowering the expiring cost of the product stocked, increasing space in a warehouse, avoiding exceed inventory, and decreasing labor costs. Moreover, from the perspective of customer service, the adoption of RFID could increase customer responsiveness in terms of reducing stock out risk, increasing the accuracy of product delivery, and increasing the interaction between customers with the organization.

Anticipating Blockchain as Disruptive Technology
Authors: Nambobi Mutwalibi , Ruth Kanyana
Published: August 2020

Today, people are going to senior managers in almost all industries pitching about their “I have a new product” thing. Disruptive technology transforms a differentiated product that was so expensive and sometimes complicated or sophisticated into a simplified implementation with the applicability of APIs. APIs provide a platform where startup companies can be nitrated to a giant and established companies. Secondly, it changes the business ecosystem to suit all kinds of players small or big. In previous years, only major companies with a lot of resources had access to such technologies. This selfish access to new technologies would make such giants flourish like Amazon, eBay, Google. Blockchain is a form of distributed ledger technology gaining significant research devotion in numerous areas cutting across e-commerce, cryptocurrency, cryptography, logistics, security, finance, and now it is gaining grounds in e-commerce, big data, and internet of things. This chapter introduces the concept of blockchain, applications, and benefits it possesses in various fields related to e-commerce.
Delphi Technique in the Development of Emerging Contents in High School Science Curriculum
Authors: Cahapay Michael Bobias
Published: August 2020

Science serves as a primary launching pad for emerging content in education. This paper examines how the Delphi technique is used in the development of emerging content in the high school science curriculum. A systematic review allowed for the search, assessment, analysis, and synthesis of related studies. The results showed that, aside from its classical form, the Delphi technique has been modified by either simplification or extension of its stages. It was further disclosed that most modified forms have deviated from the key trait of the Delphi technique of maintaining the anonymity of the involved participants, adopting a panel discussion. This deviation, however, is an answer to the weakness typically criticized for the classical form that does not account for active interaction among the participants. The recommendation for curriculum developers on how to combine the strengths of the varying Delphi techniques is offered in the study.

Taboos and Storytelling for Teaching and Learning in Zimbabwe
Authors: Sithole Pindai Mangwanindichero , Bondai Beatrice Maupa
Published: August 2020

This paper explores how taboos and storytelling could be applied in the curriculum decolonization agenda of Africa through the Zimbabwe's Curriculum Framework for Primary Education adopted in 2015. The main question that underpinned the discussion was, What role could taboos and storytelling play towards a framework design for education decolonization at primary and high school levels in Zimbabwe and elsewhere in Africa? The theories that guided the reflective analysis and arguments advanced in the paper are Postcolonial theory and Afrocentric theory because of their complementary nature for the subject matter studied. The study found that taboos have a fear-deterrence effect to teaching and learning discourse while storytelling promotes ‘peership' and social equality among the learners. The study concluded that taboos and storytelling are just a few of the many possible African indigenous knowledge resources that could be considered towards curriculum decolonization framework at primary and high school levels in the continent.
The Confrontation With the Stranger and Intercultural Considerations in the Travel Report
Authors: Leibrandt Isabella Monika
Published: August 2020

This article draws on a teaching experience in the form of a literary conversation in a German as a foreign language class and presents didactic approaches to the travel report The Walk from Rostock to Syracuse by F.C. Delius. As it thematises the motif of the educative journey as a longing for education and freedom, the work is analyzed in a close relation to the genre of the Bildungsreise based on classical models such as the Italian journey of Seume and Goethe. The literary educative journey leads the learners into a wider contextual knowledge as traveling in times of the German separation. As educative aspects of the reading, strangeness and aesthetic experience are taken into reflection by adopting different didactic methods such as the focus and integration method. In order to reach an adequate reading comprehension, learners are challenged by coping with the intertextuality and hybridity of the text.

Crowdsensing-Based Gamification for Collective Assistance for Post-Era of Coronavirus Epidemic in Community Living
Authors: Luo Renfei , Marques João Alexandre Lôbo , Ong Kok-Leong , Fong Simon
Published: August 2020

Crowdsensing exploits the sensing abilities offered by smart phones and users' mobility. Users can mutually help each other as a community with the aid of crowdsensing. The potential of crowdsensing has yet to be fully realized for improving public health. A protocol based on gamification to encourage data sharing and mutual assistance is proposed. The game is called “Lemmings,” which stands for location-based mutual and mobile information navigation system; it is based on a classical video game where a group of creatures have to work and win through the puzzle game together. This game includes an asynchronized messaging system where a player may proactively seek for answers or advice by depositing a question on the messaging server. The server will automatically disseminate the question, which is related to a specific location, to a group of users who are either within the proximity currently or have just recently been there. The users/players are encouraged to help each other in post-pandemic Corona virus period; karma scoring distinguishes the most helpful users in the community.
Analysis of Xq27.3 Fragility Using the Micronucleus-Fluorescence In situ Hybridization Assay
Authors: Özer Leyla , Ruhi Hatice Ilgın , Bökesoy Işık
Published: August 2020

Chromosome fragile sites tend to form gap or break in chromosomes when the cells are exposed to replication stress. Folic acid deprivation in the culture medium induces folate-sensitive rare fragile sites, such as FRAXA which is responsible for the fragile X mental retardation syndrome. Chromosome instability at fragile sites can be evaluated by biomarkers of genomic instability such as frequency of micronuclei (MN). It was aimed to analyse the chromosome content of MN in Fragile X cells during folate deprivation by the MN-fluorescence in situ hybridization (FISH) method. Samples from five Fragile X syndrome patients, diagnosed using cytogenetic and molecular methods, as well as from their parents and five controls were included in the study. Blood samples were cultured in two different culture media (folate-deficient and normal). Results of MN-FISH test were analysed in terms of MN frequency and chromosome content of MN. An accumulation of MN in Fragile X patients, mainly containing T (+) or C (+) MN or T (+) plus C (+) MN in binucleated cells was found. Finally, MN-FISH analysis allowed confirming that the increase in MN frequency is due to a higher sensitivity to chromosome breakage along the X chromosome.
Ethiopia’s 2006 Legal Education Reform Programme: Aspirations and Standards
Authors: Stebek Elias N.
Published: August 2020

Ethiopia’s Legal Education Reform Programme (launched in 2006) was based on series of studies which identified the problems in Ethiopia’s legal education, the causes and consequences of the problems and the standards that are required to be attained by law schools. After more than a decade, however, the level of compliance with the standards is still an issue of concern. This calls for self-assessment by each law school based on check-list regarding (i) the level of awareness about the standards for Ethiopian law schools, (ii) standards that are partly achieved and should be enhanced, (iii) what has not been achieved and should be pursued, and (iv) the problems that have been aggravated. Such self-assessment requires closer examination into the entry point (i.e., student admission and academic staff employment), inputs, processes, student-learning environment, and outputs. This article discusses the factors that necessitated the 2006 legal education reform programme and examines the core elements of the reform without, however, dealing with the details on achievements and challenges.

Uncertainties in the Enforcement of Loan Agreements in the Informal Credit Markets in Ethiopia
Authors: Yimer Gebreyesus Abegaz
Published: August 2020

Credits from informal credit markets are commonly used by those who have limited access to formal financial institutions. There is no comprehensive legal framework that deals with informal credit markets in Ethiopia. The lack of clear, effective and enforceable legal framework to regulate transactions in the informal credit markets has created uncertainty on the applicable laws. Legal contentions on the formation of valid loan contracts and in relation to interest rates have caused ambiguities and inconsistent patterns of interpretation among courts, legal professionals and parties who are involved in the informal credit markets as borrower or lender. This article examines how the provisions of the Civil Code that regulate contract of loan are used and interpreted by courts and contracting parties. Thirty court cases are used to examine how courts apply the provisions of the Civil Code in their decisions in loan related cases in the context of informal credit markets.

A Note on Resolution of Tax Disputes Arising from DTTs and Implications for Developing Countries
Authors: Byness Aschalew Ashagre
Published: August 2020

Countries sign bilateral double tax treaties (DTTs) to avoid or mitigate double taxation in cross border economic activity. It is hardly possible to ignore the effect of double taxation in the era of globalization. DTTs are signed between two countries to allocate tax jurisdiction between them and to avoid tax disputes between the taxpayer and the country concerned. Nonetheless, tax disputes crop up since such treaties may be open to interpretation at the time of implementation. Hence, DTTs contain tax dispute resolution mechanism. The widely recognized dispute resolution mechanisms are the mutual agreement procedure (MAP) –a kind of negotiation between the two contracting states– and compulsory arbitration. However, the aptness and efficacy of these tax dispute resolution mechanisms have been seriously questioned particularly from the vantage point of developing countries such as Ethiopia. Although Ethiopia has signed several DTTs with a view to attracting FDI, no study has been made which sheds some light on the essence and operation of the MAP in the DTTs. This note aims at exploring the tax dispute resolution mechanisms incorporated in DTTs since such mechanisms have implication for developing countries including Ethiopia.

Implementation of State Policy in the Field of Guardianship and Trusteeship: Regional Aspect
Authors: Koroleva Elvira V. , Volynchuk Yana A.
Published: August 2020

The objective of the work is to review the implications of the implementation of state guardianship policy in the Primorsky territory of the Russian Federation. The institution of the family is the most important factor for the development of the child's personality; its role is constantly growing in the development and education of children. Without a doubt, the family is a natural educational environment for a child who leaves his mark on his behavior and character. A special place in the modern legal system is occupied by the aspect of the right of the child and the protection of the interest that is left without the care of the parents. Methodologically, use was made of the documentary research technique close to legal hermeneutics. It is concluded that the guardianship and guardianship bodies perform a series of important functions for any civilized state, namely: identification of people who need to establish one of the forms of guardianship (adoption); adoption of such persons, as well as increased supervision of the guardian, the activities of the adoptive parents and of persons authorized by the state to care for those who need their help.

There is a need to determine the patient's condition in the process of establishing legal relationships with the medical institution, as well as guaranteeing their human rights. The issue of guaranteeing the rights of patients with mental disorders has become particularly acute, which has led to the relevance of this study. For this reason, the objective of the article is to determine the status of the patient with mental disorder in civil law relationships, between him and the medical institution by examining the respective legal literature, the jurisprudence of the European Court of Human Rights and the Acts. national and international legal. In the course of the study the following methods were used: dialectical, structural and systemic, analytical and synthetic, analytical and synthetic, comparative and legal, formal and legal, sociological. The study found that reform of existing legislation has led to a new regulatory policy in the area of healthcare. There are no specific rules in civil law that determine the status of the patient with a mental disorder, as well as the possibilities and methods of protection of their rights. Furthermore, mental health services, given their details, need to be further regulated at the legislative level.
Investigating the Realism or Idealism of Iran's Legislative Criminal Policy
Authors: Vanaki Ahmadreza , Salehi karim , Nematollahi Meysam
Published: August 2020

This document addresses problems and questions that arise about realism or idealism in the context of the criminal policy of the double legislature in Iran, with the aim of revealing the available skills and capacities of the laws that govern the matter. Has the Iranian lawmaker followed an idealistic criminal policy? Is realism what is necessary for a dimensional criminal policy in Iran's criminal laws? What is the solution to the transition from religious idealism to a realist perspective preserving the status quo? What is certain is that, when examining existing criminal law, criminal policy based on religious idealism and dimensional realism can be seen in terms of criminological data; from the oldest data in criminal law to the latest criminal paradigms. Methodologically, documentary research technique and legal hermeneutics were used. It is concluded that traditional theologically based laws and sharia-based oversight bodies need a new dynamism and a new ijtihad. In this study, the dimensions of the subject and the form of transcendence from idealism to realism are given while preserving religious values.
Pilares de la estabilidad de los regímenes autocráticos: análisis del caso de Venezuela
Authors: Medina Verónica , Carrillo Víctor
Published: August 2020

Desde finales de la década del 90 el mundo ha presenciado el surgimiento de autocracias con atributos cada vez más sofisticados. Estas se caracterizan por ser democracias establecidas que experimentan retrocesos graduales en sus sistemas de libertades. En este contexto, estudios académicos recientes han indagado sobre los determinantes de la estabilidad de las autocracias contemporáneas. Este trabajo se inscribe en esta línea de investigación, proponiéndose responder las preguntas: ¿Cuál es la configuración de los determinantes de la estabilidad del régimen autocrático de Venezuela?, y ¿Dicha configuración tiende hacia la estabilidad o inestabilidad de su autocracia? El objetivo es analizar los determinantes de la estabilidad autocrática del régimen venezolano. Para tal propósito se elaboró una revisión documental de estudios que examinan el caso venezolano. La data recolectada se clasificó y analizó en base al modelo de los tres pilares de la estabilidad autocrática de Gerschewski (2013). La evidencia empírica arroja que actualmente el régimen venezolano se sostiene en base a la aplicación de severas prácticas de represión y cooptación. Sin embargo, el desempeño precario de sus políticas públicas y la merma en su base de apoyo ideológico han disminuido severamente sus niveles de legitimación, catalogando al sistema como una autocracia inestable.
Political structure and the administration of political system in Iraq (post-ISIS)
Authors: Majeed Hameed Muntasser
Published: August 2020

The objective of the investigation was to analyze the structure and administration of the political system in Iraq (post-ISIS). After 2003, the Iraqi political system suffered the fundamental problem of its failure to achieve the political and social inclusion that characterizes democratic systems, to guarantee the establishment of a "state for all", while respecting differences. Political representation has moved from the system of sectarian ethnic components, under the title of consensual democracy, to the representation of leaders and the realization of their interests and the interests of their parties at the expense of the groups that claim to represent them, which complicates the problem. In this sense, the new political system could not represent social pluralism, on the one hand, and could not satisfy the demands of the same components on the other. Methodologically, it is a political investigation in the framework of the analysis of the political system. It was concluded that the search for new balances is a pending issue. While these emerging balances and arrangements are still fragile and immature to the extent required, they represent a clear entry point to reshape the regime's political structure in one form or another.

Métodos ativos de ensino podem ser entendidos como recursos para o combate à evasão em cursos de graduação em Física? Uma análise das relações entre os fundamentos de métodos ativos e a evasão universitária com base nas ideias de Vincent Tinto
Authors: Moraes Kaluti , Heidemann Leonardo , Espinosa Tobias
Published: August 2020

Métodos ativos de ensino têm sido vastamente investigados na literatura da área de Ensino de Ciências. Esses estudos têm demonstrado, entre outras coisas, que atividades que promovem um papel ativo dos estudantes, favorecendo o engajamento nas aulas de Ciências, contribuem para melhores resultados de aprendizagem. Investigações como essas levaram pesquisadores a assumirem a implementação de métodos ativos como estratégia para combater a evasão em cursos universitários. Em alguns casos, admite-se que melhores resultados de aprendizagem colaboram para uma diminuição nos índices de reprovação, culminando em menos estudantes que abandonam a graduação. Esse argumento, amplamente utilizado para defender a implementação de métodos ativos de ensino, ainda que seja pertinente, pode ser enriquecido a fim de melhor dirigir ações didáticas e de pesquisas. Nesse sentido, o objetivo deste artigo é evidenciar as relações entre a implementação desses métodos e a decisão de persistir ou de evadir de estudantes em cursos superiores, especialmente em cursos de ciências exatas, expondo exemplos particularmente relacionados com o ensino de Física. Para isso, tomamos como referencial a teoria interacionista de Vincent Tinto. Buscamos, fundamentados em resultados da literatura, mostrar como a implementação de métodos ativos de ensino auxilia para melhorar as percepções dos estudantes sobre: i) suas capacidades para suprirem as demandas do curso (crenças de autoeficácia); ii) seu pertencimento como membros de uma comunidade que valoriza suas participações na instituição (senso de pertencimento); e iii) o valor e/ou relevância dos estudos previstos no currículo dos seus cursos (percepção de currículo). Com isso, contribuímos para a área de Ensino de Ciências proporcionando um quadro teórico para o delineamento, a condução e o estudo de ações institucionais focadas no combate à evasão universitária.

Published: August 2020

Este artigo apresenta uma Revisão Sistemática de Literatura (RSL), que tem por objetivo analisar as finalidades e as potencialidades dos aplicativos educacionais móveis em pesquisas em ensino de Física realizadas no âmbito dos programas de mestrados profissionais. A busca pelas dissertações ocorreu no banco de teses e dissertações da Capes. Tomamos por período de recuperação dos trabalhos as publicações a partir do ano de 2015. O critério de inclusão ficou estabelecido da seguinte forma: a dissertação deve apresentar propostas de atividades de ensino desenvolvidas, testadas e analisadas com o uso de aplicativos educacionais móveis para o ensino de Física. Com esse recorte, foram obtidas 20 dissertações para a análise. Conforme apontam os trabalhos selecionados nessa RSL, o uso dos smartphones a qualquer momento e espaço permite que as aulas de Física ultrapassem os limites da escola; facilita o acesso a jogos digitais educacionais em contextos narrativos, interativos e desafiadores; possibilita o uso de simulações, vídeos e animações, que contribuem na visualização de conceitos abstratos e na realização de experimentos virtuais que não podem ser realizados em laboratórios convencionais; e potencializa a aquisição de dados em atividades práticas, explorando os sensores e aplicativos disponíveis.
Atividades experimentais de Física da revista Ciência Hoje das Crianças
Authors: Martins Jéssica Taynara , Oliveira Elrismar Gomes
Published: August 2020

A revista Ciência Hoje das Crianças (CHC), criada pela Sociedade Brasileira para o Progresso da Ciência, se destaca como material paradidático de divulgação científica na educação básica brasileira por sua distribuição pelo Programa Nacional do Livro e do Material Didático (PNLD) no Brasil. Desde o final do século XX são realizados estudos sobre a importância das atividades experimentais no ensino de Ciências que objetive a alfabetização científica. As pesquisas recomendam que o encaminhamento das atividades deve partir de um problema, não se limitando à manipulação ou observação. Ressaltam também que as crianças dos anos iniciais de escolaridade são capazes de fazer reflexões e buscar explicações, indo além da mera execução de roteiros ou da contemplação. Assim, o objetivo desse trabalho é apresentar a análise das atividades experimentais de Física propostas na CHC. O resultado mostra que a CHC está na contramão do que recomendam as pesquisas em ensino de Ciências. As atividades experimentais apresentam características empírico indutivistas marcadas por uma visão rígida da Ciência. Permitem pouca ou nenhuma liberdade para atuação criativa e reflexiva dos estudantes, sem espaço para erro ou discussão dos resultados. A revista não é um material didático e não explicita entre seus objetivos a alfabetização científica. Porém, considerando as pesquisas em ensino de Ciências das últimas décadas, acreditamos que um material que pode compor as bibliotecas de mais de 150 mil escolas públicas brasileiras não pode encaminhar concepções estereotipadas da Ciência como, por exemplo, a visão empírico-indutivista. Pelas dimensões do PNLD e sua política de avalição de materiais distribuídos, a CHC deveria se destacar como mediadora entre as pesquisas e o ensino nas escolas.
À luz da Ciência na Educação Infantil: Desafiando a imaginação infantil a desvendar fenômenos ópticos

Published: August 2020

Este trabalho apresenta uma análise da visitação de crianças de 4 a 6 anos à exposição À Luz da Ciência na Educação Infantil, promovida pela Universidade Federal do Pampa, a partir de uma proposta de divulgação e popularização da ciência sobre a temática Luz. A proposta fez parte das comemorações do Ano Internacional da Luz (2015), tendo recebido fomento do Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) para sua realização em dois campi: Bagé (em 2016) e Caçapava do Sul (em 2017). Descrevemos neste trabalho as treze estações do circuito da exposição, analisando, em seguida, como as crianças, acompanhadas por suas professoras e monitores da universidade, interagiram com os experimentos e artefatos, bem como sua capacidade de expressar conceitos científicos relacionados à temática, tais como: reflexão, refração, energia luminosa, luz e sombra e outros. Como, na época, as crianças ainda não dominavam a escrita e a leitura, os dados sobre a experiência de visitação foram reunidos por meio de desenhos e comentários feitos por elas após terem percorrido todo o circuito da exposição. O encantamento e a alegria durante a visita à exposição deixaram a certeza de que é possível tornar o conhecimento científico acessível para crianças dessa faixa etária e que a curiosidade é o elemento mais importante a ser explorado durante uma exposição interativa, pois elas se mantêm atentas e receptivas ao que lhes desafia a imaginação.

Abstract. The coupled atmospheric–hydrologic modeling system is an effective way to improve the accuracy of rainfall–runoff modeling and extend the lead time in real-time flood forecasting. The aim of this study is to explore the appropriate coupling scale of the coupled atmospheric–hydrologic modeling system, which is established by the Weather Research and Forecasting (WRF) model and the gridded Hebei model with three different sizes (1 km×1 km, 3 km×3 km and 9 km×9 km). The Hebei model is a conceptual rainfall–runoff model designed to describe a mixed runoff generation mechanism, including both storage excess and infiltration excess, in the semi-humid and semi-dry area of northern China. The soil moisture storage capacity and infiltration capacity of different
grids in the gridded Hebei model are obtained and dispersed using the
topographic index. The lumped Hebei model is also used to establish the
lumped atmospheric–hydrologic coupled system as a reference system. Four 24 h storm events occurring at two small- and medium-scale sub-watersheds in northern China are selected as case studies. Contrastive analyses of the
flood process simulations from the gridded and lumped systems are carried
out. The results show that the flood simulation results may not always be
improved with higher-dimension precision and more complicated system, and
the grid size selection has a strong relationship with the rainfall evenness. For the storm events with uniform spatial distribution, the coupling scale has less impact on flood simulation results, and the lumped system also performs well. For the storm events with uneven spatiotemporal distribution, the corrected rainfall can improve the simulation results significantly, and higher resolution leads to better flood process simulation. The results can help to establish the appropriate coupled atmospheric–hydrologic modeling system to improve the flood forecasting accuracy.

Abstract. This paper proposes a line-matching algorithm based on feature grouping and a line band descriptor (LBD) to address the insufficient reliability of individual line descriptors for line matching. First, the algorithm generates line-pairs according to geometrical relationships such as the distances and angles between line segments extracted from a single image. Subsequently, the algorithm employs the epipolar line of intersection between two lines in a reference line-pair to constrain candidate pairs corresponding to the reference line-pair. Thereafter, each line in the reference line-pair is considered individually, and its support region and the corresponding support region of each candidate line in the candidate pairs are established, following which an affine transformation is used for unifying the sizes of the reference support region and the candidate support region. Moreover, the LBD descriptor is then used for describing the reference and candidate lines. The Euclidean distances between the reference line and each candidate line descriptors are calculated, and the nearest neighbor distance ratio (NNDR) is used as a criterion for determining the final matching. Finally, the one-to-many and many-to-one line correspondences in matching results are transformed into one-to-one line correspondences by fitting multiple lines to the new line; simultaneously, incorrect matches are eliminated. The experimental results show that the proposed algorithm yields reliable line-matching performance for close-range images.

Abstract. Photogrammetry is becoming a widely used technique for slope monitoring and rock fall data collection. Its scalability, simplicity of components and low costs for hardware and operations makes its use constantly increasing for both civil and mining applications. Recent on site permanent installation of cameras resulted particularly viable for the monitoring of extended surfaces at very reasonable costs. The current work investigates the performances of a customised Raspberry Pi camera module V2 system and three additional low-cost camera systems including an ELP-USB8MP02G camera module, a compact digital camera (Nikon S3100) and a DSLR (Nikon D3). All system, except the Nikon D3, are available at comparable price. The comparison was conducted by collecting images of rock surfaces, one located in Australia and three located in Italy, from distances between 55 and 110 m. Results are presented in terms of image quality and three dimensional reconstruction error. Thereby, the multi-view reconstructions are compared to a reference model acquired with a terrestrial laser scanner.

Abstract. Computer vision applications have been increasingly gaining space in the field of remote sensing and geosciences for automated terrain classification and semantic labelling purposes. The continuous and rapid development of monitoring techniques and enhancements in the spatial resolution of sensors have increased the demand for new remote sensing data analysis approaches. For semantic labelling of 2D (or 2.5D) image terrain representations for rock slopes, it has been shown that Object-Based Image Analysis (OBIA) results in high efficiency and accurate identification of landslide hazards. However, the application of such object-based approaches in 3D point cloud analysis is still under development for geospatial data analysis. In the field of engineering geology, which deals with complex rural landscapes, frequently the analysis needs to be conducted based solely on 3D geometrical information accounting for multiple scales simultaneously. In this study, the primary segmentation step of the object-based model is applied to a TLS-derived point cloud collected at a landslide-active rock slope. The 3D point cloud segmentation methodology proposed here builds on the principles of the Fractal Net Evolution Approach (FNEA). The objective is to provide a geometry-based point cloud segmentation framework that preserves the 3D character of the data throughout the process and favours the multi-scale analysis. The segmentation is performed on the basis of supervoxels based on purely geometrical local descriptors derived directly from the TLS point clouds and comprises the basis for the subsequent steps towards the development of an efficient Object-Based Point cloud Analysis (OBPA) framework in rock slope stability assessment by adding semantic meaning to the data through a homogenization process.

Abstract. The authors group is within the Glacier Lab of Politecnico di Torino (part of the CC-LAB, a laboratory for climate change monitoring), which is working on glacier monitoring since 2016, mainly exploiting Geomatics techniques to measure the extent and to model the surface of glaciers over the years. Measurement campaigns were carried out within the ASP (Alta Scuola Politecnica – Poliecnico di Torino e Milano) DREAM projects (Drone tEchnnology for wAter resources and hydrologic hazard Monitoring) The manuscript is focused on a specific case study related to the Belvedere glacier, a valley glacier located in northern Italy.In the framework of the Belvedere glacier monitoring, several Geomatics approaches have already been applied in the last four years by the cc-glacier-lab and DREAM Projects with the goal to monitor both the extent of the glacier and its surface. Such monitoring enables the multi-temporal comparison of the glacier digital surface model (DSM), highlighting areas of ice loss and gain. Considering the limitations of aerial surveys in high altitude environments, the authors started assessing the suitability of a satellite based approach, mainly focusing on positional accuracy assessment. The paper is focused on a monitoring based on a high resolution (0.5 m) satellite optical stereo pair. Several tests were carried out with the goal to test the 3D positional accuracies, assessing the impact of different configurations of Ground Control Point (GCP) in terms of numerosity and distribution and focusing on the DSM validation. The results demonstrated the fit-for-purpose of a satellite-based approach for glacier monitoring.
