An updated checklist of Collembola in Taiwan, with DNA barcoding of Papirioides jacobsoni Folsom, 1924 (Symphypleona, Dicyrtomidae)
Authors: Cheng Hsin-Ju , Janssens Frans , Chang Chih-Han
Published: October 2022

From urban green space to pristine forest, Collembola is one of the most numerous and species-rich members of the soil fauna around the world. However, due to lack of taxonomic expertise and research, its diversity is poorly understood, especially in tropical and subtropical regions. Collembola biodiversity studies in Taiwan have not seen much progress since 1981, when Hsin Chi reviewed 26 species belonging to 20 genera and eight families. Additionally, reports of new records in Taiwan in the last 40 years are scattered amongst several publications and not easily accessible to most end-users. Thus, a concise summary of related research is urgently needed. In this study, we updated the checklist of Collembola in Taiwan, based on published papers as well as images recorded in 2020–2022. We concluded that 58 species of Collembola belonging to 31 genera and 12 families have been reported in Taiwan, including 13 newly-recorded species. This species richness marks a 123% increase from the 1981 review. The results have been made publicly available in the Catalog of Life in Taiwan database and the images recorded have been used to update species information in collembola.org. We also characterised morphological and genetic variations in the globular springtail speciesPapirioides jacobsoniFolsom, 1924 using DNA barcodes and highlighted potential research directions.
Multigene phylogeny of the Indo–West Pacific genus Enosteoides (Crustacea, Decapoda, Porcellanidae) with description of a new species from Australia
Authors: Hiller Alexandra , Werding Bernd
Published: October 2022

The porcellanid genus Enosteoides Johnson, 1970, currently containing six species, was raised in the 1970s to contain aberrant Indo–West Pacific forms of the diverse and cosmopolitan genus Porcellana Lamarck, 1801. Here, we describe the most aberrant form as Enosteoides spinosussp. nov., from the northeast and northwest coasts of Australia and present results on phylogenetic reconstructions of the genus, based on an 1,870 bp alignment of concatenated DNA sequences of three mitochondrial and one nuclear gene. The new species is peculiarly spiny and has a higher morphological affinity to the type species of the genus, E. ornatus (Stimpson, 1858), than to the other congeneric species. Our molecular results indicate that Enosteoides is not monophyletic. The new species and E. ornatus are encompassed in a clade, which does not share immediate common ancestry with the clade containing the other species of Enosteoides. This clade is more closely related to species of Porcellana and Pisidia. Relatively large interspecific genetic distances between and within the two clades, as compared to distances estimated in American pairs of species on each side of the Panama Isthmus, suggest ancient divergence, probably followed by extinction events or low speciation rate. Relatively large intraspecific distances between Australian populations of the new species of Enosteoides from geographically distant locations suggest some level of phylogeographic structure.
La Chine d’aujourd’hui : « paradis contrefait » ou « bel enfer » ?
Authors: Becker Catherine
Published: October 2022

La société chinoise contemporaine s’est créée autour de la tentation du luxe mise en système. La classe moyenne a été happée par cette tentation, qui comprenait l’appel d’un ailleurs, la tentation de l’Occident, et en même temps répondait à la philosophie, la politique et l’histoire chinoise. Mais « ce paradis contrefait » s’est vite transformé en « bel enfer » du sacrifice et de la corruption. Aujourd’hui cependant la tentation d’un nouveau luxe permet de se redéfinir soi-même au cœur de la société.
« Mes couleurs brillent sous le soleil de l’hippodrome. » Posséder un pur-sang en Afrique du Sud
Authors: Chevalier Sophie
Published: October 2022

L’auteure s’interroge ici sur les modalités suivant lesquelles un cheval de course peut être considéré comme un « bien de luxe ». Elle montre que le pur-sang est le résultat d’un processus de mise en valeur, d’« enrichissement », qui le transforme en « bien de luxe ». Cette mise en valeur de l’animal passe par la création d’une généalogie qui l’immortalise, ainsi que par les nombreux récits de ses victoires historiques. Le cheval en tant que tel n’appartient pas à une classe spéciale de biens – même en tenant compte du fait qu’il s’agit d’un être vivant, il entre plutôt dans un registre spécial de consommation, qui s’inscrit dans un monde social, construit spécifiquement autour de l’animal. L’analyse de ce monde social permet aussi à l’auteure d’explorer les transformations sociopolitiques que traverse la société sud-africaine post-apartheid.
La prise en charge psychiatrique au Sénégal
Authors: Ndoye Fatou , Sylla Aida , Dieye Mouhamed Moustapha , Samba Ly Bocar
Published: October 2022

Cette étude porte sur l’évolution de la prise en charge psychiatrique au Sénégal à travers l’histoire du service de psychiatrie au CHNU de Fann-Dakar. Celle-ci était fortement marquée par l’orientation que lui a imprimée le médecin militaire français qui a fondé « l’École de Fann » à la fin des années 50. Par le truchement d’une analyse diachronique, les données recueillies montrent que la psychiatrie s’est progressivement éloignée de l’organisation originelle, en l’occurrence l’approche ethnopsychiatrique, pour s’orienter davantage vers une pratique purement médicale en dépit du fait que les représentations culturelles et religieuses sont toujours prégnantes.
Acceptabilité de la vaccination contre la poliomyélite dans la commune urbaine de Labé
Authors: Diallo Salmana
Published: October 2022

Les motivations et perceptions des populations concernées ont été peu prises en compte lors des campagnes de vaccination en Guinée et à Labé. Notre article se propose d’interroger les facteurs d’acceptabilité de la vaccination anti poliomyélite dans la commune urbaine de Labé (République de Guinée). Une analyse qualitative de l’expérience des populations éligibles à cette vaccination a été réalisée sur 74 entretiens individuels et 4 focus groups . L’étude met en évidence une acceptabilité fortement liée aux expériences historiques des populations et à la circulation de certaines rumeurs, ainsi qu’une perception qui varie vis-à-vis du vaccin, de la campagne de vaccination et des acteurs qui y sont impliqués. Ainsi, l’acceptabilité de la vaccination anti poliomyélite dans la commune urbaine de Labé est complexe, au regard de la diversité des facteurs sociaux, historiques, organisationnels et stratégiques qui entrent en jeu.
La maison un lieu d’intimité : incidences transculturelles
Authors: Eiguer Alberto
Published: October 2022

La maison est le lieu privilégié de l’intimité avec soi et de celle que l’on entretient avec les autres, l’extimité. Cela étant, les lieux dans la maison où ces intimités se développent influencent voire forgent, le caractère des résidents ainsi que le fonctionnement familial. L’auteur l’étudie au niveau de la cave et du grenier, des espaces d’intimité et de mémoire. On les vit de manière singulière, leur attribuant des oppositions et de la complémentarité. Certains mythes africains sur le masculin et le féminin aident à comprendre pourquoi les humains chargent ces endroits de tant de symboles. L’auteur illustre ces idées par une expérience personnelle.

« Sales gauchers ! » : la stigmatisation humoristique des gauchers dans les arts martiaux historiques européens
Authors: Jennings George
Published: October 2022

Les gauchers, qui représentent 10 à 13 % de l’humanité, sont surreprésentés dans les sports de combat. Pourtant, au cours des siècles, le fait d’être gaucher a été associé à la malchance, à la maladresse, à la sorcellerie et à la diablerie. Les styles d’escrime historiques et les manuscrits qui les expliquent ont été élaborés à l’intention de droitiers qui combattaient des adversaires eux aussi droitiers. Les versions réinventées de ces arts martiaux historiques européens ( HEMA , AMHE), qui prospèrent aujourd’hui partout dans le monde, forment une sous-culture à part et spécifique. Cet article s’inspire d’une ethnographie en cours de la Blade Academy (pseudonyme) au Royaume-Uni, sur la base de mon propre apprentissage et de mes observations comme gaucher. Inspiré par le métacadre des corps linguistiques (Di Paolo et al ., 2019), j’examine comment les techniques destinées à l’origine aux droitiers sont adaptées aux gauchers. Fondée sur l’idée de stigmate de Goffman (1963) et celle de « violation bénigne » ou benign violation (McGraw & Warren, 2010), mon analyse décrit les approches humoristiques de la stigmatisation dans un monde de droitiers. Les blagues sur ces « sales gauchers » (par opposition aux « droitiers et aux justes ») évoquent des siècles de stigmatisation depuis l’époque romaine, alors que la sinistra (« sinistre », au sens littéral) constitue désormais un sujet de plaisanterie. J’entends montrer que l’inclusion de groupes précédemment exclus (comme celui constitué par les gauchers) est bien accueillie, même si l’humour qui l’accompagne révèle un fonds historique de discrimination.
A SEMI AUTOMATED MODEL FOR IMPROVING VESSEL SYSTEM RELIBAILITY AND MAINETANANCE MANAGEMENT
Authors: Daya AA , Lazakis I
Published: October 2022

The demanding nature of Naval operational requirements leads to rapid deterioration and decline in the reliability of ships systems and machineries. In most Navies ships built with design life of 25-30 years begin to significantly decline in performance around 7-8 years after joining service. Consequently, these leads to frequent and often prolonged downtime and huge maintenance cost. The Nigerian Navy like other navies is equally faced with this situation in a challenging manner due to the introduction of new platforms and to non-standardised data management. Therefore, a data management approach that is focused on the use of maintenance, repair, and overhaul (MRO) data is proposed. The proposed approach will build on the existing data collection and management practiced in the Nigerian Navy while identifying alternatives for both onboard and fleet level maintenance data collection and management. In this regard a platform for a predictive machinery condition monitoring approach based on failure mode and component criticality is proposed. In this research a methodology for data collection and fault labelling is presented. Diagnostic analysis using Feedforward Artificial Neural Network classification model was used for fault classification.
COUPLING A HIGH FIDELITY NEAR SURFACE EFFECTS MODEL INTO PARAMARINE S4
Authors: Crossland P , Forrest C J M
Published: October 2022

When a submarine is operating at depths typical of those required when using the periscope, snorting during the period of recharging the batteries or, in some cases, at slow to zero speed whilst hovering, the submarine can experience complex
oscillatory motion due to higher order sea loads. The second order vertical plane loads can manifest themselves as a mean and time varying suction force effectively causing the submarine to be drawn to the surface risking broaching and increasing the possibility of detection. Current methodologies for modelling near surface effects tend to utilize coefficientbased methods to represent the first and second order wave forces on a submarine body. These empirical methods may be suitable for some applications but are not able to capture all the effects of the submarine operating close to the free surface. As the body approaches the free surface, the flow field around the submarine is modified by the gravitational wave effects, changing the pressure distribution across the body and hence the forces and moments. This change in force is dependent
upon the shape of the body and the environment and, therefore, it is impractical that a coefficients-based approach could cover all these scenarios to any great level of fidelity. This paper presents a potential flow method for quantifying the
hydrodynamic loads on a fully appended submarine when in proximity and under the influence of surface waves. The paper presents some validation of the method and describes its integration with the Paramarine S4 submarine manoeuvring
software.
AUTONOMOUS MOBILE ROBOTS’ INTRODUCTION IN SHIPYARDS'
MANUFACTURING PROCESS
Authors: Dentesano C
Published: October 2022

In the context of an exponential growth of digitalization in the naval production process, the introduction of emerging technologies becomes a key point for the future competitiveness of companies. As a matter of fact, it is fundamental to
optimize the process, exploiting newest solutions to improve production tracking, quality control and timesaving. Specifically, autonomous mobile robot technologies (AMR) are becoming increasingly relevant in recent years, thanks to
the advances in the scientific community and to the growing number of market options.

In this scenario, it was decided to use AMRs to face different problems in the shipyard, such as autonomous inspections and material transport, to provide our employees with a concrete and automated support during the tasks of every day. As
a result, our work led to a cloud ecosystem where our workers have the possibility to assign specific tasks to robots, like setting up real stocktaking missions or making requests for missing material, while putting their effort in more worthwhile
activities. Humans and different kinds of mobile robots can operate within the same environment without hindering each other, and the autonomous mode can be easily turned into a controlled one.

In the following, we are going to present the research and development journey which took us to the deployment of a concrete solution for improving both efficiency and quality of our shipyards, which fits perfectly into the framework of
digital innovation of our company.
AUTOMATED GENERATION AND LOW-EFFORT AUTHORING OF COMMISSIONING CONTENT IN THE MARITIME INDUSTRY
Authors: Elzalabany A , Settler V , Jansen T , Rost R , Lödding H
Published: October 2022

Commissioning in the maritime industry is a long crucial phase in which all essential components in the ship are tested for faults and defects before a final acceptance form is signed by the client. Due to the variety of components in a ship and
the complex hierarchical structure of such components, it is typical to have thousands of tests that should be performed throughout the commissioning phase. For every new ship, commissioning planners initially spend hours preparing the commissioning tests by reading technical documents, extracting relevant information, and applying the gathered knowledge to the unique equipment configuration in the ship. This leads to high preparation efforts and planning mistakes, e.g., unconsidered dependencies, and as a result, commissioning, and the shipbuilding process as a whole may be delayed.

This paper lays the foundation for automating the process of authoring commissioning content for maritime productions. The paper presents a digital modeling approach for ship components, which facilitates the development of commissioning-specialized software. The model shown in this paper takes textual and geometrical information of ship components as input data and produces generalized commissioning templates that can be used to generate commissioning tests automatically.
VIRTUAL REALITY BEYOND DESIGN REVIEWS IN SHIPBUILDING: THE NEED FOR INDUSTRY-TAILORED IMMERSIVE DATA INTERACTION
Authors: Fourrier N , Benaouicha M , Moreau G , Normand JM
Published: October 2022

In the context of shipbuilding, the potential of virtual reality (VR) as a visualization tool has been demonstrated [1, 2]. However, many conditions must be met for VR to be widely adopted in the shipbuilding industry. It primarily must be seamlessly integrated into current workflows. The shipbuilding industry will likely first need to tame its data with efficient models accessible throughout the ship’s lifecycle. However, some productivity issues with VR have not yet been identified clearly. While working to develop a VR design tool for ship outfitting, it became clear to us that there is a need for industrydriven development of efficient data interaction and manipulation tools in VR. As an example of such new manipulation tools, we are currently developing a new way to input text in VR that is efficient and easy-to-learn through handwriting. The evaluation of this system highlights the need for more controlled and systematic testing of VR tools in the shipbuilding industry to justify investments and adoption.
VEHICLE HOT SPOT DETECTOR AND DANGEROUS GOODS DETECTOR TO FIRE IGNITION PREVENTION IN RO-RO SHIPS
Authors: Haas M , Brumm H , Wallimannand L , Oe T , Marrero A
Published: October 2022

Nowadays, all cargo (except dangerous goods) is loaded without consideration to the hazards they pose, opening the door to improvements from the fire prevention point of view by means of a custom and objective management of the units based on the potential hazards they involve. The technical approach presented here takes the systems currently used in parking lots, tunnels, tolls or logistics as starting point but applied to the maritime environment. Specifically, both Vehicle Hot Spot Detector (VHD) and Vehicle Dangerous Goods Detector (VDG) have been modified and extended with developments that now consider usual loading units in Ro-Pax, Ro-Ro and Vehicle Carrier ships. Also, a refactoring has been performed aiming at adapting the system to the environmental conditions in which it must work. The dates are used in cloud based new online stowage tools (Stowage Planning Tool) for loading optimization. This enables more safety on board.
A METHOD OF VARIABLE RECOGNITION AND CONNECTION FOR REVIEWING SHIP REGULATIONS
Authors: Kong M C , Roh M I , Kim K S , Kim J , Park H , Lee J
Published: October 2022

CSR, one of the most referenced documents in the classification, is a rule established for the safe construction of bulk carriers and oil tankers. This document contains not only extensive content but also contains complex equations, figures, and tables. In particular, some variables in the equations represent the requirements of the ships, and they are often defined with other variables. Therefore, even an expert in the review task has the inconvenience of having to search through the CSR several times to find the meaning of the desired variable. Accordingly, we devised an algorithm that automatically recognizes variables in a document and identifies the relationship between each variable. consequently, we developed a program to visualize this information for the user effectively. This study achieved variable recognition accuracy of F1- score=0.96 for CSR, and its effectiveness was confirmed by being applied to related fields.
VOYAGE OPTIMIZATION WITH WIND PROPULSION
Authors: Paakkari V , Wang H , Stigler C
Published: October 2022

Wind propulsion has been proven to produce significant fuel savings on commercial vessels. The typical savings potential of wind propulsion on conventional cargo ships is 5-25%. On the other hand, voyage optimization and weather routing has been shown to produce similarly large fuel savings in the order of 15%. Wind is an intermittent energy source, and it often occurs together with waves, making ships installed with wind propulsion especially interesting from weather routing point of view. This means that a holistic approach is needed when conducting weather routing for ships with wind
propulsion.

Using detailed simulations, this paper studies how the fuel savings potential of wind propulsion can be further improved by coupling it with state-of-the-art voyage optimization software. Via case study examples, it is shown that the savings potential of wind propulsion can be more than doubled by using voyage optimization.
A NEW APPROACH FOR USING CAD AND PLM INTEGRATION
Authors: Perez Fernandez R
Published: October 2022

During the last decades, a tight and efficient integration between the CAD and the PLM systems used in complex shipbuilding products, definition, manufacturing and operation has become a more and more important matter, in order to ensure design efficiency, avoid design errors, prevent wasting time in using wrong data or, simply, to provide a common environment in which different organizations and partners working in the same shipbuilding design programs must share their data and follow common procedures.
When we talk about CAD and PLM integration, we must distinguish between CAD systems that use individual files to store the data (files that must be put under a PLM system control to be properly managed) and CAD applications that use
their own database as a data repository.
The first one is a classic mechanical CAD to PLM integration approach, while the second is actually a proper case of systems integration, as both applications make use of their own database and both of them have to be maintained linked and synchronized, in order to guarantee data consistency and, as well, to ensure that the principle of the PLM as the “single point of truth” is maintained.
In this paper, we will be focus on the database CAD systems approach, the one used for a complete integration between FORAN and Teamcenter, where there is an increment in productivity and ease of use go together when using these new capabilities.

With the acquisition of FORAN by Siemens, it is expected to enhance the marine design and engineering capabilities soon. This is the perfect marriage, FORAN, the shipbuilding CAD tool with the longest tradition, and Siemens, always at the
state of the art of the technology.
This integration will provide a comprehensive portfolio of software and services related to all facets of a ship’s lifecycle, including concept design, production and operations, as well as optimized service lifecycle management.
We have become a key partner for the shipbuilding Industry, and although we are a global leader, we need to retain our customers and gain new ones, and in order to do that, we need to work harder providing them the best solutions.
By creating a best-in-class tool for shipbuilding, leveraging the team’s industry expertise, shipyards and technical offices will be able to have a better control of their ship design and manufacturing process as they transition to Shipyard 4.0.
There is a lot of work out-there, waiting for us to achieve a greater success, big customers with big needs, and Siemens will provide the best solution as possible.
DIGITAL PLATFORM ENABLING ROBOTIC SURVEY, REPAIR & AGILE MANUFACTURING OF SHIPS AND WATERCRAFT
Authors: Santo F T , Williams D
Published: October 2022

A recent development in Friction Stir Welding (FSW) processes allow welding of steels underwater, as a result, there is a possibility to incorporate this technology to perform in-situ repair and maintenance of ships in water. The FSW requires process parameters which are chosen and monitored by experts during welding. Having such expertise on board can
enhance the operation costs of the ship and make the technology expensive to adopt by small-sized European shipping industry. In this work we propose a Digital Platform (DP) that allows experts to monitor the FSW parameters and condition indicators remotely in the form of real-time visualisations. This approach potentially reduces the labour cost as the man hour of the expert can only use during the welding process. The real-time data is also stored in a central data lake which allow users to perform further analysis and determine the overall integrity of the weld.

The complexity of modern shipbuilding, alongside changes in a business environment and growing capabilities of digital solutions, challenges work processes and offer the possibility to gain efficiency by eliminating gaps in the information flows. The paper discusses the changes in modern ship design and production and the interconnections between these two phases of the shipbuilding lifecycle from the information management point of view. It offers several examples of shipyard practices and outlines the direction of the development for digital transformation in this area.
DEVELOPMENT OF A COMMUNICATION PLATFORM TO SUPPORT CONSENSUS-BUILDING AMONG STAKEHOLDERS IN SHIPPING DECARBONIZATION
Authors: Takahashi K , Ushijima Y , Fujita Y , Saito T , Yamato H , Kakiuchi R , Wanaka S
Published: October 2022

The carbon neutral shipping should be achieved no later than 2050. However, technologies for the propulsion and the fuel systems are not established, the fuel supply chain is not established and regulations for decarbonization are under discussion in IMO. Designing the carbon neutral ships in this transition phase has difficulties with these undetermined conditions. The optimum design of carbon neutral ships and the optimum time to install these to the market could be achieved with the cooperation across the sectors from shipyards, shipowners, operators, and more stakeholders including the government with clear provision of satisfactory profits or decarbonization results to each sector. Under this recognition, the simulator to provide the decarbonization data and cost estimation during this transition phase was developed together with the communication system to determine the best solution for all stakeholders. This paper shows the concept and
prototyping results of the communication system.
A STUDY OF PROCESS SIMULATION BASED ON A MULTI-AGENT SYSTEM FOR SHIPBUILDING
Authors: Taniguchi T , Matsuo K
Published: October 2022

This paper proposes a simulation technique for the shipbuilding process based on a multi-agent system. In this paper, we propose a simulation technique for the construction process based on a multi-agent system. In this method, the worker is
regarded as an agent and the virtual factory as an environment. Tasks are represented as a combination of more detailed elemental tasks. Three techniques, pathfinding with the A-star algorithm, placements of two-dimensional irregular shapes, and intersection with other equipment or occupied areas, were introduced to allow agents to take spatial constraints into account. It also simulates the manufacturing process by performing task selection through an evaluation function based on weight coefficients. The simulation results for sub-assembly and assembly process in a real shipyard confirmed that the
task could be reproduced with high accuracy. It is possible to capture manufacturing features in simulation in advance, without manufacturing them.
SIMULATION METHOD OF FLEET TRANSITION BASED ON TECHNOLOGY, ECONOMICS, AND REGULATION SCENARIO FOR DECARBONIZATION OF SHIPPING
Authors: Wanaka S , Kakiuchi R , Fujita N , Hiekata K , Yamato H
Published: October 2022

International Maritime Organization (IMO) adopted an initial strategy for GHG reduction from ships, and the industry has started to consider how to respond to the strategy. To strategically advance decarbonization, it is necessary to develop tools to discuss how to implement the IMO’s strategy quantitatively.
This paper proposes a method to simulate fleet transition toward decarbonization based on multiple scenarios of technology, economics, and regulation. The simulation model includes not only technical models such as energy consumption from ships and the GHG emissions but also social models of regulation for operation and operator’s decisionmaking. By inputting future assumptions of ship’s performance, fuel prices, regulation, and transportation demand, the simulation projects a transition of fleet and calculates OPEX, CAPEX, and amount of GHG emissions during the transition. The simulation enables the stakeholders of decarbonization of shipping to analyse and compare future possible strategies
of the fleet transition quantitatively.
AI/ML APPLICATIONS FOR SHIP DESIGN
Authors: Hodges J , Wheeler M P , Belhocine M , Henry J
Published: October 2022

This work uses Simcenter STAR-CCM+ to generate CFD data for determining the powering characteristics of a vessel and Simcenter ROM Builder and Monolith for using that data in no-code machine learning pipelinesto allow hull designers to understand how design variants affect vessel performance instantly. Firstly, in terms of capabilities, the machine learning models were able to predict several 0D performance metrics (torque, total resistance, powering, and propulsion metrics) with respect to 12 independent geometrical parameters involved in the ship design. These predictions were then supplemented with additional machine learning predictions of the spatial flow field as well to provide designers with more detailed understanding of the hydrodynamic aspects of the vessel. Regarding the spatial fields, there are two main capabilities the machine learning models provided: predict results of spatial fields in the form of local contours (loads on the hull, free surface deformation, and in-flow into the propeller), and thereby also an optimization pipeline which can morph the geometry according to the desired cost function for any combination of these machine learning predictions.

Os objetos informacionais empregados no campo brasileiro se difundem e ampliam sua participação em diversos ramos produtivos. No setor do agronegócio, esse sistema de objetos técnicos, envolvendo sensores, equipamentos e máquinas, conectados digitalmente através da Internet das Coisas (Internet of Things ou IoT), permite o compartilhamento de grandes volumes de dados dos mais variados tipos com grande fluidez, alimentando diversas etapas do processo produtivo, tais como detecção e monitoramento de atividades agropecuárias, processamento industrial de alimentos e análise preditiva das variáveis meteorológicas. As operações são realizadas remota e automaticamente por equipamentos como smartphones, tablets e maquinários agrícolas computadorizados e equipados com GPS. A partir do advento da Internet das Coisas, o ritmo de crescimento da produção de dados e sua velocidade de transmissão aumentam exponencialmente e demandam a conexão dos estabelecimentos rurais e etapas da produção às redes de telecomunicações. A análise dos agentes envolvidos no desenvolvimento, difusão e conexão desses sistemas e a avaliação de seus impactos na produção agropecuária permitem visualizar dois processos complementares e contraditórios no campo brasileiro: 1) o aprofundamento das desigualdades, decorrente da difusão social e espacialmente seletiva das tecnologias digitais; 2) a potencial mitigação dos efeitos deletérios da primeira tendência, isto é, das disparidades entre os agentes do circuito superior e do circuito inferior das economias agrárias, por meio da difusão e banalização do uso das tecnologias da informação e infraestruturas de internet no contexto da agricultura familiar, valorizando os conhecimentos diversos de pequenos e médios produtores e cooperativas.

L'article met en perspective les voyages d'Elisabeth II dans un monde où l'influence britannique décline. La tendance est claire: en dehors des voyages dans les pays européens (notamment en France et en Allemagne), les plus nombreux ont été faits dans les pays dont la reine a été la souveraine jusqu'au bout, notamment le Canada (22 voyages) et l'Australie (15 voyages) et les îles des Caraïbes et du Pacifique restées sous souveraineté britannique. Puis, par ordre décroissant, dans les pays du Commonwealth, avec une préférence pour ceux dont elle était restée la souveraine.
Impactos da pandemia de COVID-19 no setor hoteleiro: os casos de Lisboa, Maputo e São Paulo
Authors: Cruz Rita de Cássia Ariza da , Brito-Henriques Eduardo , Larrabure Sara , Isidoro Chundo Dário Manuel
Published: October 2022

Este artigo tem por objetivo fazer uma análise exploratória das mudanças observadas no setor hoteleiro em três cidades de três países e continentes diferentes. Complementando informação proveniente de bases de dados oficiais, de pesquisa direta junto dos estabelecimentos hoteleiros e dos sites dos hotéis, além de entrevistas com representantes do setor, inventariam-se e analisam-se as mudanças observadas na oferta hoteleira em Lisboa (Portugal), Maputo (Moçambique) e São Paulo (Brasil), entre 2020 e 2021. Os resultados mostram que a suspensão da atividade, com encerramento temporário nos períodos mais críticos da pandemia, e a redução parcial da oferta para diminuir os custos operacionais foram as estratégias mais comuns seguidas pela hotelaria nas três cidades, com consequências como perda de emprego. Outras mudanças de caráter mais estrutural, como processos de rebranding e encerramento definitivo de hotéis, encontraram variações significativas entre as cidades estudadas, o que em parte se deve à adoção de políticas diferentes nos vários países e a exposição variável dessas localidades ao turismo internacional.

O presente artigo tem por objetivo analisar a ação governamental em resposta à crise do transporte aéreo, adotando como estudo de caso Brasil e Moçambique, observando se estes países seguiram as tendências mundiais de suporte às empresas, ou se, por conjunturas nacionais específicas, deram respostas distintas ao setor ao longo dos anos de 2020 e 2021. Para isso, foi realizada pesquisa bibliográfica e documental. Os resultados mostram que as tendências apontadas para o setor aéreo foram concretizadas em parte em ambos os países. No Brasil, o suporte financeiro se deu de modo indireto, por meio de ações que garantiram sobrevida às companhias aéreas, enquanto em Moçambique a transferência de recursos públicos foi direta.
Efeitos da Pandemia da Covid-19 na dinâmica do turismo de segundas residências em Armação dos Búzios/RJ e Bertioga/SP: transformações e permanências
Authors: Abreu Luciano Muniz , Beil Isabella Maria , Barretti Daniel De Renzo
Published: October 2022

O presente trabalho busca analisar as principais transformações e permanências relacionadas ao fenômeno do turismo de segunda residência frente ao contexto da pandemia do Sars-Cov-2 no Brasil, entendida aqui como elemento acelerador de processos que já vinham sendo experienciados pelo fenômeno antes da crise sanitária. Parte-se do entendimento de que as chamadas residências secundárias, sua espacialização e as dinâmicas a elas atreladas se expressam por meio de uma imbricada relação de fatores e contradições socioespaciais. Nesse sentido, em que pese a ocorrência de transformações quanto ao uso das residências secundárias, verifica-se que essa prática continua a convergir para uma, cada vez maior, possibilidade de ganhos financeiros e para uma maior desigualdade e segregação socioespacial. Os resultados demonstram que a pandemia tem tido papel relevante na aceleração desses processos. Tomam-se, como casos exemplares da investigação, dois importantes balneários turísticos litorâneos, onde há forte incidência de residências secundárias, Bertioga/SP e Armação dos Búzios/RJ, que, pela proximidade às duas principais metrópoles nacionais, São Paulo e Rio de Janeiro, respectivamente, mantêm com estas fortes relações concernentes ao turismo. As análises, fundamentalmente qualitativas, são complementadas por dados quantitativos relacionados ao fenômeno em estudo, subsidiando as inferências e as interpretações dos achados.

Entrepreneurs are increasingly turning to digital transformation to bolster their organizations' overall resiliency, and academics and practitioners alike are taking note. Organizational resilience and digital transformation have been studied extensively in the literature. This research used quantitative and structural equation modelling (SEM) to investigate the connections between digital transformation, innovation, and organizational resilience via a questionnaire survey with 203 entrepreneurs in Lebanon. According to the findings, the digital transformation of businesses improves their ability to withstand external threats. This study also demonstrates three ways to achieve organizational resilience: digital transformation, innovation, and company diversification. Entrepreneurial innovation positively impacts organizational resilience. The chapter concludes by stressing the relevance of the practical significance of digital transformation for businesses to implement it and create greater organizational resilience properly.

Authors: Wijesinghe Chaminda , Hansson Henrik , Ekenberg Love
Published: October 2022

Information and communications technology (ICT) represents an enormous opportunity to introduce significant and lasting positive changes across the developing world. Several attributes determine behavioural intention to adopt the technology. Some elements will stimulate end users' intention to use the technology, while others are detrimental. This study is designed to measure the relationship between various factors on individuals' perceptions of adopting an ICT-based instrument to stimulate ICT innovations. A model was developed by combining the technology acceptance model and the diffusion of innovation theory. A survey questionnaire was distributed among students and teachers in higher education and industry professionals working with university collaborations. A sample of 202 responses was analysed using structural equation modelling. A good insight into user acceptance and the adoption of a systematic model to reinforce ICT innovations are provided in this study with the derived results. Theoretical and practical implications for the factors influencing the acceptance of the system are discussed.

The process of semen collection plays a key role in the quality of semen specimens. However, the association between semen collection time and semen quality is still unclear. In this study, ejaculates by masturbation from 746 subfertile men or healthy men who underwent semen analysis were examined. The median (interquartile range) semen collection time for all participants was 7.0 (5.0–11.0) min, and the median time taken for semen collection was lower in healthy men than that in subfertile men (6.0 min vs 7.0 min). An increase in the time required to produce semen samples was associated with poorer semen quality. Among those undergoing assisted reproductive technology (ART), the miscarriage rate was positively correlated with the semen collection time. After adjusting for confounders, the highest quartile (Q4) of collection time was negatively associated with semen volume and sperm concentration. A longer time to produce semen samples (Q3 and Q4) was negatively correlated with progressive and total sperm motility. In addition, there was a significant negative linear association between the semen collection time and the sperm morphology. Higher risks of asthenozoospermia (adjusted odds ratio [OR] = 2.06, 95% confidence interval [CI]: 1.31–3.25, P = 0.002) and teratozoospermia (adjusted OR = 1.98, 95% CI: 1.10–3.55, P = 0.02) were observed in Q3 than those in Q1. Our results indicate that a higher risk of abnormal semen parameter values was associated with an increase in time for semen collection, which may be related to male fertility through its association with semen quality.
Congenital Thrombotic Thrombocytopenic Purpura Simulating Alloimmune Thrombocytopenia

Published: October 2022

Congenital thrombotic thrombocytopenic purpura (cTTP) is a thrombotic microangiopathic caused by severely reduced activity of the von Willebrand factor-cleaving protease A Disintegrin And Metalloproteinase with a Thrombospondin type 1 Motif, member 13 (ADAMTS-13), which leads to small-vessel platelet-rich thrombi, thrombocytopenia, and microangiopathic hemolytic anemia (MHA) in the absence of neutralizing antibodies. We describe a case of cTTP in a female neonate presenting initially on the 1st day of life with asymptomatic thrombocytopenia thought to be alloimmune thrombocytopenia, then progressed to severe neonatal jaundice, pallor, and MHA, in whom ADAMTS-13 levels <5%, and the anti-ADAMTS-13 antibody titer was negative confirming the diagnosis of cTTP. The patient initially received intravenous immunoglobulin infusion before documenting MHA. She received fresh frozen plasma infusions which successfully reversed the MHA (by supplying ADAMTS-13) and prevented organ damage in this patient.

We describe the 18F-fluorodeoxyglucose positron emission tomography/contrast enhanced computed tomography (FDG PET/CECT) images of a 63-year-old male who complained of back pain and was suspected of multiple myeloma based on magnetic resonance imaging. PET/CECT suggested the FDG avid lesion involving prostate, accompanied by multiple lytic skeletal lesions with no evidence to suggest other possible primary site. A bone marrow biopsy suggested a metastatic adenocarcinoma of primary prostatic origin. Post anti-androgen therapy follow-up FDG PET/CT revealed reductions in the metabolic activities and soft tissue components of most of the metastatic skeletal lesions. These images highlight the possible indication of FDG PET/CT in evaluation of prostatic malignancy in era of 68Ga-PSMA.

Authors: Osama Md A. , Dhawan Shashi , Khetan Mukund , Rawat Kishan S.
Published: October 2022

Inflammatory myofibroblastic tumor (IMT) is a tumefactive proliferation of spindled myofibroblastic cells admixed with inflammatory infiltrate. This tumor has a predilection for the involvement of visceral soft tissues and has a tendency for local recurrence. Occurrence of metastatic or metachronous IMTs is a rare presentation. We report a rare case of a 50-year-old man with metastatic IMTs in the colon and duodenum.

Authors: Panigrahi Pradeep Kumar
Published: October 2022

A 37-year-old healthy male presented with sudden loss of vision in the left eye (LE) 1 week following starting oral steroids for COVID-19 complications. Best-corrected visual acuity in the left eye (LE) was 20/80, N12. Clinical and imaging tests led to a diagnosis of central serous chorioretinopathy in the LE. There was gradual resolution of neurosensory detachment following the discontinuation of steroid therapy. Two months following initial presentation, best-corrected visual acuity in the LE had improved to 20/20, N6.

Published: October 2022

Background:

This study was designed to compare the overall success rates and complications of two techniques of internal jugular vein (IJV) catheterization, namely the landmark (LM)-based technique and ultrasound (US)-guided technique in a heterogeneous Indian population at an Armed Forces Tertiary Care Hospital.

Methods:

Ninety consenting patients were assigned to two groups: LM and US groups. Patients with known coagulation abnormalities, body mass index > 30, infection at the insertion site, known vascular abnormalities, burn contractures, and other dermatologic conditions that precluded an LM technique were excluded. Central venous catheterizations during the code blue scenarios were excluded due to the emergent nature of the procedure. Three operators from the author group with requisite experience in LM and US techniques performed the 90 catheterizations. In LM group, a finder needle with a 2 ml syringe was used to aspirate venous blood from the IJV. A 16G needle was guided in the same direction as the finder needle till venous blood was aspirated, followed by guidewire insertion and cannulation. In the US group, a 6–12 MHz linear US probe was used to identify the IJV in real time and a 16G needle was used to access the IJV under US guidance in the cross-sectional view.

Results:

The overall success rate was 84.4% in LM group and 100% in US group (P = 0.0059). The first attempt success rate was similar in both groups (71.1% and 86.6%, P = 0.07). The overall complication rates in LM group were 20%, whereas complications in the US group were 2.2% (P = 0.0073). Notably, vascular complications occurred less frequently in US group with fewer arterial punctures and hematomas. Hemothorax and pneumothorax did not occur in any group. The mean cannulation time decreased by 69 s, i.e., from 276 s in the LM group to 207 s in the US group (P < 0.001).

Conclusion:

US-guided central venous catheter insertion to IJV improves the overall success rate and reduces cannulation time as compared to conventional LM-based technique.
