O COMPORTAMENTO DO PIB CATARINENSE DURANTE O PERÍODO DE DESCENTRALIZAÇÃO POLÍTICO-ADMINISTRATIVA
Authors: Munaro Maria Eduarda , Mattei Lauro
Published: December 2022

Em 2003 foi implementada em Santa Catarina a estratégia de descentralização político-administrativa, que tinha como objetivo reduzir as desigualdades regionais do estado e evitar a continuidade do processo de litoralização populacional que vinha sendo observado no território catarinense. O objetivo central do estudo foi analisar as implicações do processo de descentralização político-administrativa sobre o desenvolvimento regional catarinense a partir do comportamento do Produto Interno Bruto das mesorregiões e microrregiões de Santa Catarina entre os anos de 2003 e 2018, período de vigência da estratégia de descentralização. Os procedimentos metodológicos utilizados foram a coleta da série do Produto Interno Bruto das mesorregiões e microrregiões catarinenses disponibilizada pelo Instituto Brasileiro de Geografia e Estatística (IBGE), o deflacionamento de toda a série tendo como base o ano de 2003, e a análise dos resultados ao longo do período de vigência da descentralização político-administrativa, buscando comparar o cenário de 2003 com o de 2018, além da contextualização geral de como se deu o processo de descentralização político-administrativa no estado de Santa Catarina. Os resultados indicam que não ocorreram alterações significativas nas desigualdades regionais de Santa Catarina diante do fim da estratégia de descentralização político-administrativa, uma vez que o cenário de concentração do Produto Interno Bruto não foi amenizado ao longo dos anos, mas ao contrário, acabou se agravando ainda mais, se concentrando em regiões específicas. Sendo assim, as ações de descentralização político-administrativa não foram capazes de cumprir com seu principal propósito: interromper o processo de litoralização domiciliar da população catarinense.

Published: December 2022

Este artigo tem o propósito de analisar as relações entre as atividades de empresas multinacionais e o desenvolvimento regional, ponderando o efeito moderador dos clusters nesta dinâmica relacional. Com base em dados 73 subsidiárias de empresas multinacionais estrangeiras do setor da indústria de transformação operando em 34 municípios, procuramos testar as relações entre a existência de atividades de empresas multinacionais e o nível de desenvolvimento regional. Além disso, testamos os efeitos moderadores de clusters regionais. Os resultados apontam que em Santa Catarina, as empresas multinacionais estrangeiras estão localizadas em concentrações industriais caracterizando a formação de clusters. Além disso, os municípios com maior concentração industrial apresentaram um resultado melhor de IDHM e PIB quando comparados com os municípios com menor concentração industrial. Já o impacto das atividades de subsidiárias de empresas multinacionais no IDHM e PIB apresentaram comportamento divergente. O efeito moderador dos clusters apresentou influência positiva na relação entre importações e desenvolvimento regional. Para as exportações, a influência foi positiva para PIB e negativa para IDHM.
Exploring the scope of gatherings in the causation of COVID-19 outbreaks
Authors: Shrivastava Saurabh RamBihariLal , Shrivastava Prateek Saurabh
Published: December 2022

The ongoing coronavirus disease – 2019 (COVID-19) pandemic has changed the dynamics of all sectors and has significantly impacted the functioning of the healthcare delivery system. The purpose of the current review was to explore the significance of gatherings in COVID-19 outbreaks and the strategies to be implemented prior to organize a gathering to minimize the potential risk of a COVID-19 outbreak. An extensive search of all materials related to the topic was carried out in the PubMed search engine and a total of 14 articles were selected. Keywords used in the search include COVID-19 and gathering in the title alone only. As COVID-19 infection spreads via close contact, a gathering of any size carries the definite potential to amplify the risk of transmission and initiate a new chain of disease outbreaks. In conclusion, the COVID-19 pandemic is far from being yet over, and the decision to organize a gathering has to be based on the risk evaluation, risk mitigation, and establishment of a risk communication strategy. Even with all this, zero risk does not exist, and the best approach will be to strictly implement all the prevention and control measures and be responsible in all the gatherings.
Emergent serious condition of the neonates associated with cerebral palsy in Japan
Authors: Suzuki Shunji
Published: December 2022

Objective: To analyze the emergent serious conditions contributing to cerebral palsy (CP) of neonates without a history of the necessity of neonatal resuscitation within 5 minutes after delivery in Japan. Methods: To examine the clinical courses regarding CP cases, we reviewed the summary reports of antenatal- and peripartum CP cases published on the home page of the Japan Obstetric Compensation System for Cerebral Palsy (JOCSC) launched in 2009. Results: Between January 2009 and February 2016, in Japan there were 51 cases analyzed as CP due to emergent serious condition of the neonates without a history of necessity of neonatal resuscitation within 5 minutes after delivery at the Japan Obstetric Compensation System for CP. The main pathological conditions described as the cause of CP were as follows: the concept of brief resolved unexplained events/apparent life-threatening event (n = 15), neonatal Group B streptococcus infection (n = 12), herpes simplex virus infection (n = 6), neonatal hypoglycemia (n = 3), and neonatal hyperkalemia (n = 3). Conclusions: Based on the current cases, we should note that neonates are very unstable, especially in the early period after delivery.
Organ-on-a-chip for perinatal biology experiments
Authors: Menon Ramkumar , Richardson Lauren
Published: December 2022

Cell culture and organ explant systems have traditionally been used by scientists in the reproductive biology and perinatal medicine area to address various research questions. Although most are unrelated to human pregnancy, animal models were also extensively used to study various mechanisms associated with pregnancy and parturition. However, limitations of traditional approaches have shifted the attention to the use of organ on a chip (OOC) technology. OOC platform simulates an organ using cells, and OOCs are biomimetic microfluidic systems comprising multiple cell types from an organ that mimic the environment of a physiological organ. OOC maintains intercellular interactions and helps to recreate organ physiology as expected for utero in perinatal medicine research. This short review introduces some basic concepts of OOC, and its utility based on some published reports.

On January 6th, 2023, our long-term colleague, Professor Roman Levitskii should have celebrated
his 80th birthday. The present issue of Condensed Matter Physics, covering the recent advances in the
physics of ferroelectricity and multiferroics, had been inspired by the Editorial Board’s wish to mark this
date with a collection of papers on the subject of his major interest throughout his long and fruitful life in
science. As the collection had been prepared for print and the present paper was being written, a sad news
arrived that after a long battle with diabetes Roman Levitskii passed away on October 28th, 2022. This
is a big loss for us and for the entire scientific community of Ukraine. The present issue now becomes a
tribute to our late friend and mentor and a bittersweet celebration of his lifelong achievements.
Critical exponents of the order parameter of diffuse ferroelectric phase transitions in the solid solutions based on lead germanate: studies of optical rotation
Authors: Adamenko D. I. , Vlokh R. O.
Published: December 2022

In this work we show that the critical exponents of the order parameter (CEOPs) of diffuse ferroelectric phase transitions (DFEPTs) occurring in lead germanate-based crystals can be determined using experimental temperature dependences of their optical rotation. We also describe the approach that suggests dividing a crystal sample into many homogeneous unit cells, each of which is characterized by a non-diffuse phase transition with a specific local Curie temperature. Using this approach, the CEOPs have been determined for the pure Pb5Ge3O11 crystals, the solid solutions Pb5(Ge1-xSix)3O11 (x = 0.03, 0.05, 0.10, 0.20, 0.40) and (Pb1-xBax)5Ge3O11 (x = 0.02, 0.05), and the doped crystals Pb5Ge3O11:Li3+ (0.005 wt.), Pb5Ge3O11:La3+ (0.02 wt.), Pb5Ge3O11:Eu3+ (0.021 wt.), Pb5Ge3O11:Li3+, Bi3+ (0.152 wt.) and Pb5Ge3O11:Cu2+ (0.14 wt.). Comparison of our approach with the other techniques used for determining the Curie temperatures and the CEOPs of DFEPTs testifies to its essential advantages.
Dielectric relaxation induced by oxygen vacancies in Na0.5Bi0.5TiO3 ceramics
Authors: Sidak V. M. , Trubitsyn M. P. , Panchenko T. V.
Published: December 2022

Dielectric permittivity was studied in ceramics of relaxor ferroelectric bismuth-sodium titanate Na0.5Bi0.5TiO3. The measurements were performed on as sintered and heat treated in vacuum samples. The diffuse dielectric anomalies associated with the structural phase transitions were observed in as sintered samples. The intense peak of permittivity (εmax ∼ 104) appeared after heat treating in vacuum. The anomaly of ε(T) was contributed by slow polarization processes (f < 10 kHz) and was non-stable, vanishing on heating in air up to ∼ 800 K. Temperature and frequency dependencies of ε were described by using Cole-Cole model with accounting thermally stimulated decay of the non-stable polarization. It is supposed that the dielectric anomaly is determined by space charge polarization mechanism. Oxygen vacancies VO•• and electrons localized on titanium ions Ti'Ti are assumed to be responsible for the phenomenon observed.
Shell-model and first-principles calculations of vibrational, structural and ferroelectric properties of KH2PO4
Authors: Menchón R. E. , Torresi F. , Lasave J. , Koval S.
Published: December 2022

We develop a shell model (SM) for potassium dihydrogen phosphate (KDP) which is fitted to ab initio (AI) results that include nonlocal van der Waals corrections. The SM is comprehensively tested by comparing results of structural, vibrational and ferroelectric properties with AI and experimental data. The relaxed structural parameters are in very good agreement with the AI results and the available experimental data. The Γ-point phonons and the total phonon densities of states (DOSs) in the ferroelectric and paraelectric phases calculated with the developed SM are in good overall agreement with the corresponding AI and experimental data. We also compute the effective Debye temperature as a function of T which shows good accordance with the corresponding AI and experimental results. Classical molecular dynamics (MD) simulations obtained with the developed SM show a FE-PE phase transition at ≈ 360 K in remarkable agreement with ab initio MD calculations.

Authors: Vdovych A. S. , Levitskii R. R. , Zachek I. R.
Published: December 2022

To investigate the caloric effects in the CsH2PO4 ferroelectric, a modified pseudospin model of this crystal is used, which takes into account the dependence of the parameters of interaction between pseudospins on lattice strains. The model also takes into account the dependence of the effective dipole moment of a pseudospin on the order parameter. In the two-particle cluster approximation, the influence of the longitudinal electric field and hydrostatic pressure on the molar entropy of the crystal was studied. The electrocaloric and barocaloric effects were studied. The calculated electrocaloric temperature change is about 1 K; it can change its sign under the influence of hydrostatic pressure. Barocaloric temperature change is about -0.5 K; lattice anharmonicities were not taken into account in its calculations.

SKIN TYPE CLASSIFIER
Authors: Parshionikar Sangeeta
Published: December 2022

Variations in skin diseases largely fall into the subset of skin types. Classification of Skin Types plays an essential part in the classification of skin diseases. The paper proposes an end to-end machine learning model used to classify skin type as dry, oily, or normal using Python Libraries. Skin type classification is done using Gray-Level Co-Occurrence Matrix (GLCM) for texture identification and Light Gradient Boosting Machine (LGBM). Red Green Blue (RGB) images are first resized and then converted into Gray-Scale images and then features like energy, correlation, dissimilarity, homogeneity, contrast, and entropy are extracted from a given image using GLCM. Such features give us a basic understanding of the type and texture of the image. The GLCM of the image is calculated by changing the distance and angle of the pixels within the image in a regular interval. These features after extraction are fed to the LGBM algorithm. The trained model is then deployed using Flask. Key Words: features extraction, GLCM, LGBM, skin type
Real Time DDos Attack Detection System Using Apache Flink and Gradient Boosting Algorithm

When large amounts of traffic from hundreds, thousands, or even millions of other computers are routed to a network or server to crash the system and disrupt its function to make the system crash.A DDoS attack aims to overwhelm the devices, services, and network of its intended target with fake internet traffic, rendering them inaccessible to or useless for legitimate users.DDoS attacks are designed to look like a flood of calls, or requests, made by browsers asking a web page to load.Ddos attacks are very crucial as they make the website or webapp down which leads to losses to the company.Early DDoS detection is critical for businesses because it can help protect the functioning and security of a network.Networks without a robust DDoS defense strategy may have trouble defending against the wide range of DDoS attacks, which can be difficult to trace.The problems need to be addressed with models that can manage the time information contained in network traffic flows.We can detect the attack while the initial requests are being made to the server and block the requests made by such IP addresses or if they are false dods attack warnings we can scale our app to handle the traffic.The system to be proposed should be as real time as it can be as it will help in preventing system crashes. In this System we will be using apache flink to give real time detection and for better classification of attack the gradient boosting is proposed.

Analysis on Intrusion Detection Systems to Secure IoT Networks
Authors: Shah Pranjali
Published: December 2022

The amalgamation of physical objects and the internet constitutes the Internet of things(IoT). In the subsequent times, more such physical objects will be connected to the internet and this will lead to the escalation in the attacks carried out on IoT devices and network. This is mainly due to the less memory and lack in built-in security controls. This has made IoT Security, the most researched topic in the past decade. Thus to protect IoT nodes and networks, a security mechanism called Intrusion Detection System(IDS) is brought in use.The advent of Internet of things has played a crucial role in making the lives of the people more easier and comfortable. It has improved the lives of the people in terms of several aspects like comfort and efficiency. This has overall consequently lead to what is called smart environments. When the case of real world smart environment is discussed, both security and privacy comes into play in being the key issues to be considered. But the need demands for the Intrusion Detection Systems (IDSs) to be designed for the IoT networks or environments to mitigate attack related issues. These are the attacks that exploits the vulnerabilities present in the network. The work here demonstrates the need of the fact that despite having previous technologies, we still lack a secure system that could safeguard IoT networks. In this paper, a detailed analysis is provided on IoT, security attacks in IoT, IDS, types of IDS, Machine learning and Deep learning techniques and algorithms used with IDS in IoT and current trends and research on use of IDS in securing Internet of Things is discussed. Lastly future research based on the current analysis is also examined. Keywords: IoT, IDS, Network, Security, Machine Learning, Deep Learning

Fermentation and diet diversity: Biochemical and functional properties of fermented mango (Mangifera Indica L) pulp flour
Authors: ELECHI Jasper Okoro Godwin , NWİYİ Ikechukwu U. , OBOH Emmanuel J.
Published: December 2022

Processing of plant foods has been in practice over a long period of time for various reasons; ranging from optimization of product quality, such as improvement in flavour, texture, nutrient density, and bioavailability as well as reduction in viscosity, bulkiness, and antinutritional factors/toxins or for improvement of functional properties for use in other food systems. Indigenous food fermentation is one of the oldest ‘food biotechnological processes’ dependent on the biological activity of microorganisms from which the development of fermented foods is achieved in the cultural history of human beings. Mango (Mangifera indica) is a tropical fruit plant that contains high levels of nutrients, fibre, macronutrients, micronutrients, and minerals as well as abundant bioactive compounds such as antioxidants and polyphenols reported to be an alternative to enhance body immunity. This study is to process fermented mango pulp flour and the effects of the period of fermentation time on the chemical composition and selected functional properties of mango pulp flours were examined. The fermentation time ranged from 0-72 h with Flour of the unfermented (0hr) Mango serving as control. Fermentation for 24hr to 72hrs significantly increased (p<0.05) crude protein and total ash in the flours. Ether extract and carbohydrates significantly decreased (p<0.05) in the flours with an increase in fermentation time. Significant (p<0.05) reduction in Bulk density, swelling index, and water absorption capacity occurred in the flour with fermentation. There was a significant (P<0.05) increase in Vitamin C and beta–carotene content of the fermented samples and this was constant as fermentation progressed across all the samples. Therefore, fermented mango flours have a great potential to be developed into healthy foods since antioxidants have the ability to improve immunity and anti-inflammatory response.

A Study and Critique Diligent on Contribution of Kamala Das to Indian English Poetry
Authors: Aslam Mulla Prof. Samareen
Published: December 2022

I am what I am, declares Kamala Das at the outset of her essay. The poetess asserts that she is uninterested in politics yet claims to be familiar with every leader since Nehru. She seems to be saying that she cannot help but have things imprinted in her. One of the most well-known feminists of the postcolonial era was Kamala Das. She wrote in both English and Malayalam, her native language. She wrote under the pen names Madhavi Kutty and Kamala Das for her Malayalam and English readers, respectively. She was dubbed "The Mother of Modern Indian English Poetry" for her enormous contributions to poetry in our nation. Because of the confessional nature of her writing, she has also been compared to literary giants like Sylvia Plath. We examine this literary icon's amazing life on the anniversary of her birth. One of the most important voices in Indian English poetry is Kamala Das. She is regarded as one of the key inspirations on Indian English poetry, and in 2009, The Times dubbed her "the mother of modern English Indian poetry" (www.timesonline.co.uk) in honor of her efforts. She received numerous honors for her writing, including the Asian Poetry Prize in 1998, the Kent Award for English Writing from Asian Countries in 1999, the Asian World Prize in 2000, the Ezhuthachan Award in 2009, the Sahitya Academy Award in 2003, the Vayalar Award in 2001, and the Kerala Sahitya Academy Award in 2005. Three poems she has written are By stating that she can recite these as quickly as she can identify the days of the week or the months, she is implying that these politicians were stuck in a cycle of time that repeats itself without regard for uniqueness. Time defined them rather than the other way around. Her contribution to Indian English poetry is the main topic of the paper.

Published: December 2022

Psychological distress has long been present among healthcare workers in a global scope for years. The vulnerability of HCWs towards psychological discomfort is heightened due to the nature of their work such as lengthy shifts, fast paced environment, and lack of necessary social support. It is also hard to assess. There is a pressing need to know the types and factors of healthcare workers’ psychological distress as this does not only affect them, but also their family, patients and the society. Highlighting the psychological well-being of HCWs impact their productivity, competence and lower any risk factors related. The goal of this review is to provide a summary of the prevalence of psychological distress among healthcare workers in countries belonging to the Association of Southeast Asian Nations (ASEAN). The articles and journals used for this review were gathered and collected from electronic databases such as PubMed Central, Google Scholar, and ResearchGate. The results generated in this review had the same perspectives with the other studies. Among all the types of psychological distress reported by various sources within ASEAN countries, stress was the most common. This is followed by anxiety and depression, respectively. Other types include fear, burnout, sadness, PTSD, fatigue, emotional weariness, and mental exhaustion. Healthcare workers are most exposed to various cases of conditions in their workplace and/or problems of society in relation to their work. This makes them susceptible to psychological distress which affects their quality of life and performance. There is a need to address this concern, and provide effective physical and mental support by the healthcare system and policymakers for the betterment of healthcare access and delivery to the general population. Future researchers should focus on investigating existing and psychological interventions and probable support towards the vulnerable HCWs in ASEAN and other countries.

Methodology: After the ethical approval from The University of Faisalabad under ethical approval number TUF/Dean//2019/39 the cross-sectional study was conducted in the Ophthalmology department of Madina Teaching Hospital Faisalabad which is associated hospital of the The University of Faisalabad. 58 volunteers of both gender and age ranging between 35-75 years were studied through non-probability convenient sampling technique. Duration of study was September 2018 to February 2019. Visual acuity was tested from logmar at a 4 meter distance. Color vision was tested by conventional Farnsworth D15 test, along with slit-lamp and +70D lens to evaluate retinopathy severity, after proper consent of the patient. The test was performed after taking complete ocular, medical, surgical and drug history. Each pseudophakic eye was tested monocular and each subject was tested thrice.
Results: Results were analyzed using SPSS version 22. Significant association was seen between the color vision in pseudophakic diabetic patient with background retinopathy (p<0.05), using Pearson Chi-Square. Color vision by conventional D-15 showed mean of ±2.17 and standard error of ±1.05. While pseudophakic group showed mean of ±1.05 and standard error of ± 0.116.
Conclusion: There is color defect in pseudophakic diabetic with background retinopathy. The dyschromatopsia is more in the blue axis. Color vision defect (CVD) seen more in uncontrolled diabetic than controlled. Color vision defect (CVD) increases with the course of retinopathy. Color vision checking must be made an integral part of examination specifically in diabetic retinopathy patient.

Cruise is a special type of tourist offer that includes a large market. Interests of guests - the structure of service users and their financial capabilities determine the content offered - entertainment, adventure, wellness or recreation, etc. One of the primary activities during long voyages are wellness procedures that are performed in order to preserve and improve the health of passengers. These procedures involve a multidisciplinary approach from several areas, of which tourism, medicine and physical culture stand out. The provision of services requires specific knowledge and skills, which have only recently taken their place in the nomenclature of јob titles, as well as a special direction of education. Successful effects require a proper hierarchy of treatment during procedures, but also a system of periodic evaluation. The paper presents a questionnaire with the results that was conducted on 102 guests on a cruise from Strasbourg to Köln, where passengers confirm the high quality and suitability of the program for users. The results especially emphasize the importance of the Wellness program for the quality and content of the trip itself. Training of personnel for these programs is possible and desirable in continental countries, whose graduates can find employment on one of the many cruises at sea, but also on larger passenger ships on continental navigation in the systems of rivers and canals of Europe.

The sample of participants consisted of 40 wheelchair basketball players, aged 33.9 ± 11.2 years. Anthropometric characteristics (longitudinal and circular dimensions, as well as skinfold thickness) were assessed, and agility was measured using the modified T-test and Figure-of-Eight test. The results of the one-way analysis of variance showed significant differences with very large effects between players of different functional classes in body mass, sitting height, and sitting reach height, while significant differences with large effects were recorded in the agility assessment tests: the T-test and the Figure-of-Eight test. Also, the results of the correlation analysis indicate that there are significant moderate positive correlations of sitting height and reaching height with functional classification.
UTICAJ FIZIČKE AKTIVNOSTI NA PREVENCIJU I BROJ PADOVA KOD STARIJIH OSOBA
Authors: Božić Danijel , Zelenović Milan
Published: December 2022

Redovna fizička aktivnost može da donese značajne zdravstvene benefite kod ljudi svih godina, te se potreba za fizičkom aktivnošću ne smanjuje sa brojem godina već je dokazano da ona može produžiti zdraviji i samostalniji život, spriječiti invaliditet i značajno doprinijeti poboljšanju života kod starijih osoba. Pored toga što svaka vrsta fizičke aktivnosti u određenoj mjeri pobošljava motoričke sposobnosti (snagu, koordinaciju, ravnotežu, agilnost, ...), mentalno zdravlje (samopoštovanje, kvalitet života) i umanjuje rizik od kardiovaskularnih i svih drugih uzroka smrti, redovno učestvovanje u vježbanju pospješuje mobilnost i funkcionalnu nezavisnost kod odraslih osoba. Pad je događaj u kojem učesnik bez sopstvene namjere dolazi u ležeći položaj na zemlji ili na nižem nivou. Bez obzira na zdravstveno stanje pojedinca, padovi su povezani sa nedovoljnim kretanjem, smanjenim mogućnostima za izvođenje svakodnevnih aktivnosti (oblačenje, kupanje, kućni poslovi, ...) i rizikom za prijem u ustanove u kojima se vodi briga o nesamostalnim osobama. Artritis, depresija, kognitivna oštećenja, vid, problemi s ravnotežom i neuravnoteženim hodom, smanjenje mišićne mase, kao i prekomjerna upotreba medikamenata povećavaju rizik od pada. Ukupan obim i vrsta fizičke aktinosti potrebna za starije osobe nije baš najbolje definisana. Međutim, može se zaključiti da spoj fizičke aktivnosti (treninzi snage, izdržljivosti, vježbe za razvoj ravnoteže i mobilnosti, ...) i adekvatne ishrane (dovoljan unos esencijalnih amino kiselina/izvora proteina) je od krucijalnog značaja za očuvanje fizičkog stanja, motoričkih sposobnosti i zdravstvenog statusa osoba treće dobi, a samim tim i u prevenciji padova. Cilj ovog rada se ogleda u opisu i pronalaženju najboljih trenažnih programa za prevenciju padova kod starih osoba.

Internacionalna Kanu Federacija prepoznaje 9 pojavnih oblika kanua. Jedna od veoma popularnih je kanu polo. Kanu polo je timski sport koji pripada porodici sportskih igara. Dva tima sa po pet igrača se međusobno bore da postignu veći broj golova sa vaterpolo loptom, u bazenu specifičnih dimenzija. Kanu polo se razvijao paralelno u tri slične varijante pravila i to kao alternativa veslanja za vreme vetrovitih i hladnih zimskih dana. Kanu polo sadrži najveći broj različitih tehnika u odnosu na sve veslačke sportove, dok se baratanje loptom vrši mešavinom vaterpolo, rukometnih, košarkaških i odbojkaških tehnika. Simultano rukovanje loptom, uz pregled igre i ometanje protivnika je veoma zahtevna koordinaciona aktivnost koja prevazilazi veslanje u prirodi sa različitim preprekama, kako po sadržaju tako i po dinamici. Danas se kanu polo igra u oko 40 država. Divljevodaške kanu discipline u državama zapadnog Balkana nisu razvijene na visokom nivou, dok kanu polo aktivnosti, klubovi i takmičenja uopšte ne postoje. Uvođenje kanu poloa u sistem sporta zapadno balkanskih država može biti iskorišćeno kao sredstvo za omasovljenje kajakaškog sporta, kao i za podizanje kvaliteta kajakaša primenom situacionog i nadsituacionog metoda vežbanja. Veoma zahtevne aktivnosti na različitijim treninzima, sa većom mogućnošću za takmičenje, kao i sa dužim i sadržajnijim takmičarskim kalendarom, mogu značajno unaprediti veštine potrebne za veslanje u kajaku i kanuu u svim njegovim pojavnim oblicima. Pored toga ne treba zanemariti ni ekonomski efekat razvoja kroz sportske objekte, infrastrukturu i čamce sa zaštitnom opremom, koji u jednom trenutku mogu postati osnov za organizaciju domaćih i međunarodnih takmičenja.

Cilјevi ovog istraživanja su bili da se utvrde: (1) razlike u antropometrijskim karakteristikama i agilnosti između različitih funkcionalnih klasa košarkaša u kolicima i (2) povezanost između antropometrijskih karakteristika i agilnosti sa funkcionalnom klasifikacijom košarkaša u kolicima. Uzorak ispitanika činilo je 40 košarkaša u kolicima, uzrasta 33.9 ± 11.2 godina. Procenjivane su antropometrijske karakteristike (longitudionalne i cirkularne dimenzije, kožni nabori), a za procenu agilnosti korišćeni su modifikovani T-test i osmica test. Rezultati jednosmerne analize varijanse ukazuju na postojanje značajnih razlika sa veoma velikim efektima između igrača različitih funkcionalnih klasa kod telesne mase, sedeće visine i sedeće dohvatne visine, dok su značajne razlike sa velikim efektima zabeležene kod testova za procenu agilnosti: T-testa i osmice testa. Takođe, rezultati korelacione analize ukazuju na to da postoje značajne umerene pozitivne korelacije sedeće visine i dohvatne visine sa funkcionalnom klasifikacijom.

El nacionalismo imaginó y forjó naciones cuyo corazón estuvo atravesado, desde el principio, por una diferenciación de género. El presente volumen monográfico de Ayer explora a través de diversos estudios de qué modo los discursos sobre el género y sobre la nación se han entrecruzado en la historia contemporánea de España de modos cambiantes y trascendentales.
El 1848 español. ¿Una excepción europea?
Authors: García de Paso García Ignacio
Published: December 2022

Las consecuencias del ciclo revolucionario de 1848 en España han sido interpretadas tradicionalmente en la historiografía española e internacional en clave de fracaso y excepción respecto al resto del continente europeo. Sin embargo, una nueva visión al 48 español a la luz de la historia transnacional y comparativa nos permite reinterpretar su significado y relativizar las diferencias entre las dinámicas políticas y sociales que tuvieron lugar en la Península y el resto del continente a lo largo del «año de la revolución». El objetivo del presente artículo es proponer esta nueva visión para abordar el estudio del 1848 español.

Aim to evaluate the comparative antimicrobial activity of the aqueous extracts from the aerial organs of the meadowsweet and dropwort.
Material and methods. The objects of the research were the aqueous extracts of the aerial organs of the meadowsweet and dropwort. For the preparation of the extracts we used the raw material harvested in 2021 in the village of Alekseevka, Samara Region. The antimicrobial activity of the aqueous extracts was determined by the method of two-fold dilution in the MuellerHinton broth.
Results. According to the results of screening of the antibacterial activity of the aqueous extracts from the aerial organs of the meadowsweet and dropwort, the significant activity against gram-positive bacteria of S. aureus and B. cereus strains was detected. The studied extracts demonstrated not lower antimicrobial activity than the reference samples of 0.1% alcohol solution of levomycetin (chloramphenicol) and freshly prepared 0.1% benzylpenicillin solution. The results have confirmed the prospects for further study of the aerial organs of the meadowsweet (Filipendula ulmaria (L.) Maxim.) and dropwort (Filipendula hexapetala Gilib.) as a possible source of biologically active substances with antimicrobial activity.
