A social system to disperse the irrigation start date based on the spatial public goods game
Authors: Nakagawa Yoshiaki , Yokozawa Masayuki
Published: May 2023

In paddy rice cultivation, the amount of water used during the beginning of the irrigation season is the highest. However, there is a possibility of a water shortage at this season as climate change decreases snowfall. In this study, we propose new schemes based on the public goods game to reduce peak water volume during this season by dispersing the irrigation start dates. In our agent-based model, agents determine the irrigation start date based on the evolutionary game theory. This model considers the economic variables of individual farmers (e.g., gross cultivation profit and cultivation cost), the cost and subsidy for cooperation for the dispersion of the irrigation start dates, and the information-sharing network between farmers. Individual farmers update the cooperation/defection strategy at each time step based on their payoffs. Using this agent-based model simulation, we investigate a scheme that maximizes the dispersion of irrigation start dates among multiple scheme candidates. The results of the simulation show that, under the schemes in which one farmer belongs to a group and the groups do not overlap, the number of cooperating farmers did not increase, and the dispersion of irrigation start dates barely increased. By adopting a scheme in which one farmer belongs to multiple groups and the groups overlap, the number of cooperating farmers increased, while the dispersion of irrigation start dates maximized. Furthermore, the proposed schemes require the government to obtain information about the number of cooperators in each group to determine the subsidy amount. Therefore, we also proposed the method which allows estimating the number of cooperators in each group through the dispersion of irrigation start dates. This significantly reduces the cost of running the schemes and provides subsidization and policy evaluations unaffected by false declarations of farmers.
Analysis of the Attributes of Memorable Tourism Experiences (MTE) on Airbnb
Authors: Da Cruz Andrade Davi Alysson , Ricci-Cagnacci Rina
Published: May 2023

This work aims to analyze and identify the attributes present in Airbnb Experiences. For this, it considered the seven attributes of Memorable Tourism Experiences (MTE) proposed by Kim & Ritchie (2014): hedonism, refreshment, meaningfulness, novelty, local culture, knowledge, and involvement. With a qualitative and quantitative approach, the method comprising the collection of 500 reviews from 100 experiences offered in the two biggest cities in Brazil generated a corpus of 25,742 words. The content analysis technique (Bardin, 2011) was applied to identify those attributes of the MTE based on categories defined a priori and then show the descriptive statistics of the frequencies of the identified attributes and the crossings between the variables. A new attribute was identified, named "welcoming", referring to the attitude of the "host" who offers the experience; being the most evidenced by users in 351 reviews as a positive aspect of the experience

Experiências turísticas memoráveis vêm se tornando progressivamente relevantes para o contexto do turismo no espaço rural. Para atender as expectativas de turistas, produtores e gestores locais devem conhecer as características das experiências memoráveis com o propósito de estruturar produtos turísticos que se sedimentem positivamente nas lembranças dos turistas, influenciando suas atitudes e comportamentos durante e após as viagens. Neste artigo, objetivou-se investigar o processo de desenvolvimento de técnicas e conhecimentos para a criação de experiências turísticas memoráveis junto a produtores da agricultura familiar. Realizou-se um estudo qualitativo, empregando o método da pesquisa-ação junto a 17 produtores agroalimentares de 9 municípios da Região do Campo das Vertentes em Minas Gerais. As estratégias metodológicas utilizadas foram oficinas remotas, questionários para criação de experiências via Google Forms, visita de campo e anotações em diário eletrônico dos pesquisadores. As oficinas remotas dividiram-se em cinco etapas e resultaram na criação de 12 experiências. Constatou-se que com a intervenção das oficinas os agricultores familiares foram capazes de elaborar junto aos pesquisadores um plano de oferta de experiências turísticas memoráveis, considerando aspectos de identificação, caracterização e comercialização dos produtos. O principal resultado desta pesquisa foi a construção de conhecimentos junto aos agricultores familiares de modo a promover autonomia para a oferta de experiências turísticas com inovação, qualidade técnica e hospitalidade. As 12 experiências criadas evidenciam que os produtores rurais foram capazes de associar os conhecimentos sistematizados nas oficinas com suas realidades locais e recursos naturais e culturais.
Valor da Marca do Destino, Envolvimento do Consumidor e a Percepção de Justiça de Preço De Diárias De Meios De Hospedagem Em Plataformas De Leilões Digitais
Authors: Lira de França Karen Daniele , Souza Anderson Gomes de
Published: May 2023

Com a crescente competitividade no setor de hospedagem, diversas estratégias têm sido utilizadas para conquistar o consumidor e maximizar as vendas de diárias. As plataformas digitais são os meios mais utilizados para que as empresas alcancem essa finalidade. Diante disso, este trabalho teve como objetivo analisar como a percepção de justiça de preço de diárias de meios de hospedagem, em plataformas de leilões digitais, pode ser influenciada pelo valor da marca do destino e o respectivo envolvimento do consumidor por ele. Este estudo descritivo, de natureza quantitativa, adotou o corte transversal único. No total, 416 respondentes compuseram a amostra, cujos dados foram analisados pela técnica de regressão linear múltipla e correlações entre as variáveis. Os resultados indicaram que apenas a relevância demonstrou influência positiva em relação à percepção de justiça de preço. Assim, foi possível constatar que o preço é um elemento de grande importância na negociação e não dependente da relação pessoal que o consumidor tenha com o destino e com os equipamentos que o compõe, nem tão pouco com a representatividade do mesmo. Portanto, o que prevalece para o consumidor é, na negociação, conseguir a maior redução possível do preço e, após isso, adquirir a diária do hotel.
A Trajetória do Voucher como Mecanismo de Governança do Turismo no Parque Nacional dos Lençóis Maranhenses
Authors: Bouças da Silva David Leonardo , Paixão Ravel , Costa Helena Araújo , Tasso João Paulo Faria
Published: May 2023

O voucher constitui um sistema de governança, inicialmente, desenvolvido em Bonito (MS) e, a posteriori, replicado em diversos destinos brasileiros, por assegurar a qualidade da experiência do turista, lucratividade às empresas e conservação ambiental. Este estudo objetivou compreender o funcionamento do voucher digital (VD) em Barreirinhas (MA) – principal destino de acesso ao Parque Nacional dos Lençóis Maranhenses (PNLM) – a partir das mudanças implementadas após sua experiência com o voucher único. Adicionalmente, foram levantados potenciais melhorias para o VD. Metodologicamente, trata-se de uma investigação qualitativa, exploratória e de caráter transversal, junto a nove atores sociais do turismo ligados aos poderes público e privado, e/ou associações de classe. A coleta de dados lançou mão de um roteiro semiestruturado, o qual norteou entrevistas em profundidade, realizadas entre agosto de 2020 e fevereiro de 2021. Posteriormente, empregou-se a técnica de Análise de Conteúdo. Os resultados apontam que, no funcionamento do VD, os visitantes têm autonomia na escolha das agências que ofertam os passeios. As agências se responsabilizam pela emissão do VD e coleta de dados dos clientes, fato que exige investimentos em tecnologias e mão de obra. A municipalidade, por meio do VD, assegura a arrecadação e responde pelo controle dos acessos ao PNLM, e pelo gerenciamento/custeio do VD. Para o incremento do VD, sugere-se implementar novas funcionalidades e promover mudanças na governança local. Conclui-se que o VD, embora apresente problemas que demandam soluções, contribui, efetivamente, com a governança do turismo ao gerar dados que auxiliem no planejamento/gestão do destino, ao estimular a formalização de empresas e devolver o protagonismo às agências na condução dos passeios ao PNLM.
Social protection and adaptation to climate change in Nigeria: Challenges and prospects
Authors: Anugwom Kenechukwu N. , Anugwon Edlyne E.
Published: May 2023

Depending on the desk review of cogent extant literature and documents, the paper interrogates the relevance and legitimacy of social protection as climate change adaptation mechanism in a developing society like Nigeria. Situated against the undoubted threat of climate change in the country, the paper advances the argument that social protection remains a key adaptation tool especially for poor, rural and agricultural households. Based on the above, it critiques existing attempts at social protection in Nigeria and makes a case for multiple strategies and multi-sectoral approaches to climate change adaptation with social protection in the core. While social protection may be a universal climate change response, the paper argues for its contextualization in the case of Nigeria to achieve socio-cultural sensitivity and more crucially adapt it to extant norms, values and practices in the society. Therefore, there is need to mainstream climate change issues including social protection into policies and regulations as well as incorporating the views and perspectives of the vulnerable into these. In addition, such policies and programmes should be informed by the local knowledge and practices of groups in the society.  The paper concludes that with the infusion of the above, social protection could overcome structural challenges in Nigeria and emerge as an attractive adaptation option to climate change.

Published: May 2023

One of the aspects that need to be considered in designing a submarine is the effect of the hydrodynamic aspect on resistance and maneuverability in various operating conditions. In certain conditions, submarines operate in conditions near the seabed. In general, submarines are designed to operate in submerge and surface mode. However, under certain conditions, submarines need to operate near the surface of the seabed. Only a few papers or journals have discussed the hydrodynamic aspects of submarines in their operating mode near the seabed. Several methods such as numerical and physical modeling tests can be used to predict the hydrodynamic capabilities of a submarine. This paper discusses the effect of the hydrodynamic aspects that occur in submarines when operating near the sea bed using the numerical CFD method. This method has high flexibility compared to experimental methods and does not require a long time to get the results. In this simulation, a submarine model with a length of 2 m is used.

Authors: Felayati Frengki Mohamad , Sugianto Erik , Octaviani Nilam Sari
Published: May 2023

Greenhouse gas (GHG) emissions are the most influential issue in the transportation sector in recent years due to their impact on the environment. Thus, the design of transportation power plants is necessary to ensure the lowest GHG emissions. However, the development of a small vessel power plant is discussed in this study. The small vessel is a marine debris working vessel that has the purpose of collecting marine debris on the water surface with a conveyor. This vessel is designed with a dual-fuel engine fueled by natural gas from CNG and diesel fuel in high load conditions. Furthermore, the power system is designed with a systematical assessment condition based on the operational condition. Moreover, an experiment was conducted to study the performance and emissions of the engine. The hybrid system is designed with several operational conditions, such as sailing, collecting, and maneuvering. Most of the operations can be used in the hybrid dual-fuel system with nearly similar engine torque to diesel mode. The dual-fuel hybrid system has a significantly low engine fuel consumption with low CO2 emissions. However, relatively high NO2 and CO emissions are still considerable.

CSF-1R promotes vasculogenic mimicry via epithelial-mesenchymal transition in nasopharyngeal carcinoma cells
Authors: Mo Huaqing , Lv Yanru , Gao Shan , Chen Zenan , Xu Zhiyong , Shen Jingyi , Zhou Shu , Yin Mengjie , Xie Yanyan , Hao Yanrong
Published: May 2023

Objectives

In nasopharyngeal carcinoma (NPC), the main factors for treatment failure are local recurrence and metastasis. Vasculogenic mimicry (VM), formation by invasive cancer cells mimicking the vasculogenic network, is strongly correlated with tumor therapy resistance and distant metastasis. CSF-1R was substantially expressed in NPC patients with a poor prognosis, according to an earlier study of ours. However, whether CSF-1R affects progression through vasculogenic mimicry deserves consideration.

Methods

By cultivating NPC cells that had CSF-1R overexpression in three-dimensional culture and labeling the NPC xenografts with CD34-PAS vasculogenic mimicry markers, the effect of CSF-1R on VM formation, migration, and invasion of NPC cells was evaluated. Finally, the underlying mechanisms were investigated by western blot.

Results

In vitro and in vivo, overexpressing CSF-1R in NPC cells causes the development of vessel-like structures. Meanwhile, NPC cells migrated and invaded more readily in the Transwell experiment when CSF-1R was highly expressed. Mechanistically, our research indicates that CSF-1R may control cell plasticity by activating the PI3K/AKT signaling pathway, promoting the formation of VM in these cells by facilitating the epithelial-mesenchymal transition.

Conclusions

CSF-1R in NPC progression by increasing VM production to increase nutrient supply to tumor cells and promote cancer cell invasion. Furthermore, these findings suggest that CSF-1R is a new promising therapeutic target aimed at treating VM in NPC.
Local performance evaluation of AI-algorithms with the generalized spatial recall index
Authors: Müller Patrick , Braun Alexander
Published: May 2023

We have developed a novel metric to gauge the performance of artificial intelligence (AI) or machine learning (ML) algorithms, called the Spatial Recall Index (SRI). The novelty is the spatial resolution of a standard performance indicator, as a Recall value is assigned to each individual pixel. This generates a distribution of the performance of a given AI-algorithm with the resolution of the images in the dataset. While the mathematical basis has already been presented before, here we demonstrate the usage on more datasets and delve into in-depth application examples. We examine both the MS COCO and the Berkeley Deep Drive datasets, using a state-of-the-art object detection algorithm. The dataset is degraded using a physical-realistic lens-model, where the optical performance varies over the field of view, as a real camera would. This study highlights the usefulness of the SRI, as every image has been taken by realistic optics. A generalization, the GSRI is introduced, from which we derive SRIA, weighting with object area and SRIrisk intended for autonomous driving. Finally, these metrics are compared.

UMA REVOLUÇÃO ESTÉTICA: O ABSTRACIONISMO DE INAH (1959-1979)
Authors: Corrêa e Silva Rebecca
Published: May 2023

Antes mesmo do abstracionismo se consolidar como nova linguagem pictórica no Rio Grande do Sul, Inah D’Ávila Costa (1915-1998) iniciou o que viria a ser uma revolução nos modos de ensinar, fruir e produzir arte na cidade de Pelotas (RS). Apesar da sua relevância na constituição do sistema das artes pelotense, atestada em estudos recentes, Inah ainda é pouco conhecida, se comparada à notoriedade alcançada pelos seus colegas homens de profissão. Para compreender as possíveis razões desse apagamento, recorremos à História das Mulheres (PERROT, 2008) sobre a perspectiva de gênero (SCOTT, 1992; 1995), observando as matizes interseccionais deste conceito através das categorias raça/etnia & classe e geração/ faixa etária & estado civil. O texto apresenta um recorte de vinte anos (1959-1979), significativo do percurso da pintora, posto que foi o seu período maior atividade. A análise deste período foi baseada em fontes de suportes diversos, como cartas; reportagens e críticas dos jornais locais e no depoimento oral de uma sobrinha.Palavras-chave: Gênero; História das Mulheres; Pintura abstrata.UNA REVOLUCIÓN ESTÉTICA: EL ABSTRACIONISMO DE INAH (1959-1979)Resumem:  Antes mismo del abstraccionismo consolidarse como nuevo lenguaje pic­tórico en Rio Grande del Sur (RS), Inah D’Ávila Costa (1915-1998) empezó lo que vendría a ser una revolución en las maneras de enseñar, fruir y producir arte en la ciudad de Pelotas /RS.

Mechanisms of Sodium-glucose Cotransporter 2 Inhibitors in Heart Failure
Authors: Wei Jiangjun , Du Jianlin
Published: May 2023

Heart failure is an end stage cardiac disease that has been associated with high mortality and rehospitalization rates in previous decades, in spite of standard anti-heart failure therapy, thus posing a major social and economic burden on public health. Several studies have demonstrated that sodium-glucose cotransporter 2 inhibitors (SGLT2i), anti-hyperglycemic drugs whose function is independent of islet function, have significant positive effects on prognosis and quality of life, by decreasing mortality and readmission rates in patients with heart failure. To increase general clinicians’ understanding and facilitate the practical application of SGLT2i in the treatment of heart failure, the mechanisms through which SGLT2i alleviate heart failure is reviewed herein.

Establishing the neural mechanisms responsible for the altered global states of consciousness during anesthesia and dissociating these from other drug-related effects remains a challenge in consciousness research. We investigated differences in brain activity between connectedness and disconnectedness by administering various anesthetics at concentrations designed to render 50% of the subjects unresponsive. One hundred and sixty healthy male subjects were randomized to receive either propofol (1.7 μg/ml;n= 40), dexmedetomidine (1.5 ng/ml;n= 40), sevoflurane (0.9% end-tidal;n= 40), S-ketamine (0.75 μg/ml;n= 20), or saline placebo (n= 20) for 60 min using target-controlled infusions or vaporizer with end-tidal monitoring. Disconnectedness was defined as unresponsiveness to verbal commands probed at 2.5-min intervals and unawareness of external events in a postanesthesia interview. High-resolution positron emission tomography (PET) was used to quantify regional cerebral metabolic rates of glucose (CMRglu) utilization. Contrasting scans where the subjects were classified as connected and responsive versus disconnected and unresponsive revealed that for all anesthetics, except S-ketamine, the level of thalamic activity differed between these states. A conjunction analysis across the propofol, dexmedetomidine and sevoflurane groups confirmed the thalamus as the primary structure where reduced metabolic activity was related to disconnectedness. Widespread cortical metabolic suppression was observed when these subjects, classified as either connected or disconnected, were compared with the placebo group, suggesting that these findings may represent necessary but alone insufficient mechanisms for the change in the state of consciousness.

SIGNIFICANCE STATEMENTExperimental anesthesia is commonly used in the search for measures of brain function which could distinguish between global states of consciousness. However, most previous studies have not been designed to separate effects related to consciousness from other effects related to drug exposure. We employed a novel study design to disentangle these effects by exposing subjects to predefined EC50doses of four commonly used anesthetics or saline placebo. We demonstrate that state-related effects are remarkably limited compared with the widespread cortical effects related to drug exposure. In particular, decreased thalamic activity was associated with disconnectedness with all used anesthetics except for S-ketamine.
Parametric Analysis of a Divided Rocker for Battery Electric Vehicles
Authors: Shafaqat Haseeb , Krüger Christopher , Urban Prof. Dr.-Ing. Peter
Published: May 2023

The driving range of an electric vehicle can be increased through an efficient integration of the large battery within the vehicle structure. In this regard, a divided rocker concept from an existing study is investigated, in which the vehicle rocker is divided into two parts by means of a division plane. One part of the rocker remains vehicle sided and enables the attachment of the surrounding vehicle structures, while the other part is functionally integrated into the side frame of the battery housing. In the scope of this paper, several division plane concepts for such a divided rocker are created and analyzed. The crash performance of the modelled division plane concepts is studied on a component level using the side pole crash test as a load case. For the different division planes, a parametric analysis is performed by varying the number of chambers in the rocker profile, the chamber width, mass distribution, individual section thicknesses, the height of the division planes, and the air gap between the vertical surfaces of the division planes. Several crash performance criteria, such as structural deformation, force, and energy absorption, are examined. Among the studied parameters, the number of chambers and mass distribution have notable influences, while individual section thicknesses and the height of the division planes do not have a significant influence on the crash performance. Lastly, stiffer chambers in the battery-sided rocker created by decreasing the chamber width have the strongest effect on crash performance.

Published: May 2023

Centrifugal pump is an instrument that is widely used in industry and has become the main driving component. A detection system is often needed to prevent damage to these pumps because they can interfere with the overall system performance. Therefore, this study discussed the development of a fault detection system for two centrifugal pump units, namely the Medium Pressure Oil Pump (MPOP) and the Water Injection Pump (WIP). In detecting the operating conditions of the pump, it was used a residual feature extraction technique in the time domain with a statistical approach. Residual was generated by using three sub-systems of a pumping system. Each sub-system was modeled using an artificial neural network with feedforward-back propagation architecture. Based on the feature values, the classifier was designed to classify pump conditions. Then the proposed fault detection system was applied in a condition monitoring system scheme. The test results (using data from the field) show that the fault detection system has an accuracy of 91.67% for MPOP and 94.8% for WIP cases. Meanwhile, the fault detection system has an accuracy above 99% during online monitoring simulations.
Numerical studies for effect of geometrical parameters on water jet pump performance via entropy generation analysis
Authors: Helios Muhammad Penta , Asvapoositkul Wanchai
Published: May 2023

This paper presented an implementation of entropy generation analysis in the main flow field of a water jet pump via the CFD method. This study aimed to identify the inefficient location of energy conversion and to analyse entropy generation sources in each region of the water jet pump. The 2D-axisymmetric model and realisable k-ε (RKE) turbulence model at steady-state conditions were performed to validate jet pump performance and to assess the entropy generation. Likewise, the effects of the projection ratio  and throat-aspect ratio as independent parameters were investigated. As a result, the throat is the most inefficient part due to the high total entropy generation rate, following by diffuser part. Also, the entropy generation rate was assessed dominant than viscous dissipation due to the turbulent dissipation, which was caused by a turbulent shear stress layer of mixing the streams. In conclusion, the projection ratio influenced the growth of the shear stress layer as well as the entropy generation. Further, the throat-aspect ratio affected the distribution of entropy generation in the throat section. An appropriate combination of both parameters has an impact on the jet pump performance improvements reducing the entropy generation rate in the future.

Published: May 2023

Cellulose acetate is an important product derived from cellulose. Cellulose acetate can be used in a variety of applications including coatings, textile fibers, consumer goods, filtration membranes, composites, laminates, pharmaceutical, and medical items. Rice husk is a lignocellulosic material that contains cellulose and hemicellulose. The aims of this study were to determine the effect of process variables on the cellulose acetate product formation by ultrasound-assisted acetylation using iodine as a catalyst and to characterize the cellulose acetate product. The research was conducted through the delignification, bleaching, acetylation, and characterization processes. The results showed that the optimum yield of cellulose acetate was obtained at the temperature of 60 °C, the reaction time of 50 min, the weight of the catalyst of 10% of cellulose weight, and the ratio of cellulose and acetic anhydride of 1:5 (w/v). The acetylation process using iodine as a catalyst with an ultrasound-assisted method was more effective than the conventional acetylation (acetic acid glacial and sulfuric acid as a catalyst).
Improvement of Eucalyptus urophylla wood permeability via urea treatment
Authors: Qin Yinluan
Published: May 2023

To increase the loading amount of modifier in wood, a simple and universal approach was developed to improve its permeability. The generated pores in wood can be backfilled with modifiers, thereby improving the function of wood. This study aimed to improve the permeability of Eucalyptus urophylla wood using a urea solution. The wood was treated under different conditions, including urea concentration, treatment duration, and temperature, and the wood permeability before and after treatment was measured using water absorption as an indicator. The treatment temperature and solution concentration had considerable effects on the water absorption capacity of the treated wood. The treatment of eucalyptus wood with a 5% urea solution for 12 h, under normal pressure, resulted in the optimal effect; water absorption reached 40%, which was 78.9% higher than that of the untreated eucalyptus. Fourier-transform infrared spectroscopy, component analysis, and BET analysis were performed to examine the mechanism underlying the effect of urea treatment on eucalyptus, which is as follows: a weak alkaline solution can dissolve the internal components of wood, namely, hemicellulose, lignin, and alcohol-benzene, which leads to the destruction of the microstructure of the wood and increases the number of micropores and mesopores in the wood.

The problem of forming ideas about an ideal marriage partner is addressed in the context of studying the influence of the moral orientation of the personality of modern young men and women. Ideas about marriage perform a guiding function in mastering the social role of the spouse. The purpose of the study is to identify the features of ideas about an ideal marriage partner (ideal husband, ideal wife) depending on the moral orientation of the personality of young men and women. Theoretical and methodological literature analysis, questionnaire, psycho-diagnostic methods (the methodology of "Personal Moral Self-determination" by A. E. Vorobieva, A. B. Kupreichenko, the method of Semantic Differential, developed by Charles E. Osgood, projective technique of "Incomplete Sentences", the questionnaire "Role Expectations and Claims in Marriage" by A. N. Volkova); mathematical and statistical data processing methods. The study involved 490 students. The moral orientation of the personality (egocentric, group-centric, humanistic, world-creating) is an individual factor that determines the originality of ideas about an ideal marriage partner among young men and women. Young women with a humanistic personality orientation are distinguished by the formation of cognitive, emotional and behavioral component in the images of "ideal husband" and "ideal wife". In the ideas about an ideal marriage partner, young men and women with a world-creating personality orientation record the greatest number of content characteristics.
