Nove spoznaje o fauni vretenaca porječja rijeke Drave

Odonata are amphibious insects widely used as bioindicators of freshwater ecosystems’ health. Their assemblages at lotic and lentic habitats in the area of the Drava River basin are still not completely known. Therefore, we surveyed Odonata fauna at two Drava River oxbows and the Drava River lower reaches in Croatia and Hungary. We recorded a total of 21 species. Although most of them were generalists, we also documented two species of conservation concern: Sympetrum fonscolombii and Ophiogomphus cecilia. During the fieldwork, we also observed some of the anthropogenic impacts present at studied habitats, such as plastic waste disposal, and removal of riparian vegetation, including the removal of individual tress for purposes of fishing. With this study, we increased our knowledge about Odonata fauna of the Drava River basin. Our data can be used for future monitoring of the recorded species and their habitats.Vretenca su amfibijski red kukaca koji se diljem svijeta koriste kao bioindikatori zdravlja slatkovodnih ekosustava. Sastav njihovih zajednica na lotičkim i lentičkim staništima porječja rijeke Drave još uvijek nije u potpunosti istražen. Stoga, inventarizirali smo faunu vretenaca dvaju rukavaca rijeke Drave i rijeku Dravu u području njezina donjeg toka na teritoriju Hrvatske i Mađarske. Zabilježili smo ukupno 21 vrstu, od čega je većina njih generalista. No, zabilježili smo i dvije vrste od konzervacijskog značaja: Sympetrum fonscolombii i Ophiogomphus cecilia. Tijekom terenskog rada na istraživanim staništima uočili smo i neke antropogene utjecaje, poput odlaganja plastičnog otpada, te uklanjanja obalne vegetacije, uključujući i sječu pojedinih stabala u svrhu izrade postaja za lov ribe. Ovo istraživanje doprinosi boljem poznavanju faune vretenaca porječja rijeke Drave te se prikupljeni podaci mogu koristiti za buduće praćenje stanja populacija zabilježenih vrsta i njihovih staništa

Automated Semantic Segmentation for Autonomous Railway Vehicles

With the development of computer vision methods, the number of areas where autonomous systems are used has also increased. Among these areas is the transportation sector. Autonomous systems in the transportation sector are mostly developed for road vehicles, but highway rules and standards different between countries. In this study, models capable of semantic segmentation have been developed for autonomous railway vehicles with the help of the public dataset. Four different U-Net models were trained with 8500 images for four different scenarios. The model trained for binary semantic segmentation reached mean Intersection over Union (mIoU) value of 89.1%, while the models trained for multi-class semantic segmentation reached 83.2% mIoU, 79.7% mIoU and 29.6% mIoU. Information about the inclusion of high-resolution images in model training and performance metrics in semantic segmentation studies shared

ASSOCIATION OF BLOOD TYPE AND MORTALITY OF COVID-19: A HOSPITAL-BASED STUDY IN NATIONAL REFERRAL HOSPITAL, INDONESIA

Background: The ABO blood type plays an important role in various diseases, such as cancer, cardiovascular, and certain communicable and non-communicable diseases. However, there is currently little definite evidence between COVID-19 with ABO blood types. Aim: The aim of this study was to determine the relationship between ABO blood type and the mortality of patients infected with COVID-19 in a national referral hospital, Indonesia. Methods: This study used a retrospective cohort.  The research sample was COVID-19 patients who were in Dr. M. Djamil Hospital Padang. The number of samples in this study was 93 subjects. Data analysis was performed using the Chi-square test. P < 0.05 was significant, and the data were analyzed using the SPSS version 21.0 program. Results: The results of this study found the percentage of mortality of COVID-19 patients was higher for blood group O (46.2%), followed by AB (41.7%), B (26.3%), and A (13.9%). There was a relationship between blood type and mortality in hospitalized COVID-19 patients (p <0.05), where blood type O had the highest risk (OR = 5.31, 95% CI 1.57-17.98) followed by blood type AB (OR = 4.43, 95% CI 1.01-19.58). Conclusion: This study confirmed there was a relationship between blood type and mortality in hospitalized COVID-19 patients, where blood type O had the highest risk followed by blood type AB

A lógica e o potencial operativo dos projectos de desenvolvimento e de intervenção social na indução de mudança

A acção para o Desenvolvimento resulta da comparação entre diferentes países e sociedades. A componente estratégica de combate ao sub-desenvolvimento tem como base o potencial operativo da Trilogia do Desenvolvimento - Políticas, Programas e Projectos - que por sua vez teve e tem como consequências imediatas a criação e proliferação de redes desenvolvimentistas a toda a escala mundial. O formato-projecto acabou por ser a mais generalizada forma de intervenção social, e tem como motores lógicas próprias de funcionamento, quer discursivas quer instrumentais, com repercussão nos impactes produzidos pelas intervenções. Procura-se nesta dissertação a teorização sobre a lógica e o papel dos projectos de intervenção na transformação das sociedades, através da análise da trilogia do desenvolvimento e do Ciclo do Projecto propriamente dito. A par disso, questões como a intervenção múltipla, a participação comunitária e a análise da sociedade civil, permitem-nos conhecer mais sobre os projectos e mais sobre os seus promotores, as suas proveniências e motivações. Nestes cenários de análise, constata-se que os mecanismos de funcionamento do complexo desenvolvimentista que mantêm o seu poder de influência, têm como base relações cíclicas institucionais de dependência, que vão permitindo a sua reciclagem e renovação constantes. Estes ciclos (viciosos) patentes nas relações institucionais têm repercussão e prolongamento aquando da operacionalização do desenvolvimento. Pois aquilo que motiva a acção é a ausência de determinada realidade ou situação que se pretende criar, e aquilo que determina a continuação da acção, continua a ser a ausência dessa realidade ou situação induzida.The action for development results from comparison among different countries and societies. The strategic component to fight underdevelopment is based on the operational potential of the Development Trilogy - Policies, Programmes and Projects - which in turn affected and affects the creation and extension of the development networks worldwide. The most common form of social intervention is the format-project. The format-project is propelled by its own operation rationales - both discursive and instrumental - which affect the outcome of the interventions. This dissertation aims to discuss theoretically the rational and the role of the intervention projects on the transformation of the societies through an analysis of the development trilogy as well as the project cycle itself. Furthermore, discussion of issues such as multiple intervention, communitarian participation, and civil society analysis, will allow us to deepen our knowledge on projects and their promoters, their backgrounds and motivations. These analysis scenarios show us the mechanisms to operate the development complex, which keeps their influential power, are based on cyclical institutional relations of dependency. This relation sustains its constant recycle and renewal. These (vicious) cycles - which are noticeable in the institutional relations - extend themselves in the development operationalization. Thus, action is motivated by the absence of a specific fact or situation one is willing to create, whereas its maintenance is determined by the absence of the induced specific fact or situation

Dragonfly fauna (Insecta: Odonata) of Papuk Nature Park, Croatia

Odonata is an amphibious insect order constituting an important link between aquatic and terrestrial habitats. Members of the group are widely used as bioindicators of freshwater habitat health. The Odonata fauna of a total of 44 freshwater habitats in the wider area of Papuk Nature Park was investigated in the spring and summer of 2017 and 2019. Twenty-three lotic and 21 lentic habitats were included in the study. We recorded 39 Odonata species, witha higher species richness (i.e. 35) documented at lentic than at lotic habitats (i.e. 16 species). Calopteryx virgo was the most widespread species in the area, while Aeshna affinis, Epitheca bimaculata, and Sympetrum meridionale were the rarest. The most frequently recorded species at lentic sites were Platycnemis pennipes, Coenagrion puella, and Ischnura elegans, while Calopteryx virgo, Onychogomphus forcipatus, and Cordulegaster bidenatata were the most common species in lotic habitats. Although we recorded numerous anthropogenic pressures in freshwater habitats in the Park, 11 recorded species are of conservation concern, which highlights the conservation value of aquatic habitats in the study area. Our results represent the first Odonata checklist of Papuk Nature Park, and as such, they are an important contribution to our knowledge of the Odonata fauna and species distribution in Croatia
