Authors: KILIÇ Abdullah Faruk , DOĞAN Nuri
Published: January 2021

Weighted least squares (WLS), weighted least squares mean-and-variance-adjusted (WLSMV), unweighted least squares mean-and-variance-adjusted (ULSMV), maximum likelihood (ML), robust maximum likelihood (MLR) and Bayesian estimation methods were compared in mixed item response type data via Monte Carlo simulation. The percentage of polytomous items, distribution of polytomous items, categories of polytomous items, average factor loading, sample size and test length conditions were manipulated. ULSMV and WLSMV were found to be the more accurate methods under all simulation conditions. All methods except WLS had acceptable relative bias and relative standard error bias. No method gives accurate results with small sample sizes and low factor loading, however, the ULSMV method can be recommended to researchers because it gives more appropriate results in all conditions.
ESTRATÉGIAS DE GESTÃO DE ESTOQUE HOSPITALAR EM ORGANIZAÇÕES PÚBLICAS NO BRASIL: UM ESTUDO DE CASO
Authors: Lopes de Souza Claudia , Gerardin Poirot Land Marcelo
Published: January 2021

O estudo tem por objetivo descrever a gestão de estoque de um serviço público hospitalar de ensino e avaliar estratégias de planejamento de compras públicas viáveis à ampla utilização em organizações públicas de saúde.

O estudo foi conduzido por meio de abordagem multimetodológica. Uma primeira etapa exploratória do sistema de gestão de estoque vigente no Hospital Universitário Clementino Fraga Filho e a segunda etapa uma análise quantitativa de estratégias de gestão e seu impacto físico-orçamentário.

A análise do caso apontou que o hospital de ensino em questão possui um bom controle de estoque, porém, não se utiliza de nenhum método formal de planejamento de compras além de não controlar custos e seu impacto orçamentário.

Problemas multifatoriais exigem soluções integradas. Aumentar orçamento nem sempre possibilitará comprar melhor. Criar consórcios hospitalares, monitorar custos de perda e manutenção de estoques, utilizar modelos enxutos e coordenados são medidas imprescindíveis para gestão pública de qualidade.

If we want to assess occupational risks predetermined by various health disorders among workers related to occupational factors and labor process factors, we need to examine whether additional methods can be applied here; these methods should allow not only quantitative determination of occupational risk but also its adequate categorizing. A procedure for risk assessment based on fuzzy sets analysis can be considered and applied for the matter. Suggested methodical approaches to occupational risk assessment based on this procedure involve step-by-step accomplishment of the following stages: determining fuzzy figures corresponding to preset occupational risk levels; preparing initial data (numeric characteristics of occupational risk) for calculations; probabilistic assessment whether a numeric characteristic of occupational risk belongs to fuzzy numbers; and estimated probability of belonging of occupational risk numeric characteristic. A basic instrument for implementing the procedure is determining a membership function for a trapezoid fuzzy number that estimates whether determined risk assessments belong to a specific risk category. We suggested a scale for assessing occupational risk levels, starting from negligible (0–1∙10-4) to extremely high (3∙10-1–1) and corresponding boundaries of trapezoid fuzzy interval (four figures that define a trapezoid number). The procedure was tested in a situation when occupational diseases (sensorineural hearing loss), work-related diseases (arterial hypertension), and their combinations were revealed under exposure to noise equal to 85 dBA; the tests allowed establishing that membership functions were equal to 1 for all risk levels determined as per results obtained via epidemiologic research.

Risk assessment methodology is a promising trend in examining effects produced by environmental factors on population health. However, at present little attention has been paid to issues related to comorbid pathologies occurrence under chronic exposure to toxicants. Our research goal was to improve methodic approaches to assessing risks of co-morbid pathology occurrence under exposure to multi-component chemical factors in the environment. Data and methods. To develop an algorithm for establishing a probability that comorbid pathology would occur, we analyzed scientific publications that focused on effects produced by technogenic chemicals on a body and health risk assessment methodology. Methodic approaches were tested with epidemiologic hygienic analysis techniques and statistical processing of data obtained via profound medical and biological examination of children living in Perm region where chemical enterprises were located. Results. We suggested a systemic approach to assessing risks of co-morbid pathologies caused by complex exposure to chemical environmental factors; the approach includes reference groups creation; determining responses in critical organs and systems via stage-by-stage modeling within «chemical factor – exposure marker – marker parameter – disease» system; determining population and individual risks of environmentally induced comorbid diseases. The performed analysis allowed establishing marker parameters of bronchial asthma and comorbid pathologies occurrence in children living on a territory with multi-component contamination of ambient air predominantly with saturated spirits, aldehydes, and particulate matter. It was shown that a number of additional comorbid diseases that were probabilistically related to increased chemicals contents in the examined children’s blood could amount up to 15‰, and a contribution made by the examined chemicals into comorbid pathology occurrence would reach 14.2–23.4%. Implementation of mathematical analysis procedures outlined in the present work will make for higher efficiency of activities aimed at managing and minimizing health risks for people living under combined exposure to chemical environmental factors.

Authors: Xu Jing , Tang Shuhui , Li Jie , Wang Wei , Wu Meihong , Zhan Xianbao
Published: January 2021

Background:

Neurokinin-1 receptor antagonists are playing a major advance in Chemotherapy-Induced
Nausea and Vomiting (CINV) as powerful prophylactic agents. Therefore, it is significant to find the association
between risk factors of patients and CINV so as to adjust the anti-emetic regimens.

Objective:

To evaluate the role of Neurokinin-1 Receptor (NK-1R) antagonist in preventing chemotherapy-induced
vomiting in the acute and delayed phases following the first cycle of treatment.

Methods:

145 adult patients with various cancers were recruited in Shanghai Changhai Hospital between
September 2017 to November 2017, receiving dual or triple antiemetics.

Results:

NK-1R antagonist combined with dexamethasone, 5-HT3R antagonist could effectively control delayed-
vomiting in patients after Cycle 1 chemotherapy treatment (4.1% vs. 15.6%, P = 0.041<; 0.05). This
study also showed that a history of motion sickness was a predictor of chemotherapy-induced vomiting (CINV)
(P = 0.023 <; 0.05). In delayed phase a low consumption of alcohol and history of CIV for males were also significantly
associated with CINV (P = 0.036 <; 0.05 and P = 0.002 <; 0.05 respectively).

Conclusion:

In this study, we found that triple anti-emetic regimen with NK-1R antagonist could effectively
prevent the delayed-vomiting than dual agents. Moreover, some risk factors were observed to be associated
with CINV in the delayed phase.

Published: January 2021

Background:

Alpha-terpineol is monoterpene alcohol with anti-tumor activity against different tumor
cell lines (lung, breast, leukemias and colorectal) through blockage of NF-kB expression, which play an important
role in tumor cells growth.

Objective:

Evaluate the antitumor activity of alpha-terpineol in murine Sarcoma 180 cell line

Methods::

For the tests, different cytotoxic and genotoxic assays were used, including Trypan blue, cytokinesis-
blocked micronucleus assay, comet assay, agarose gel DNA fragmentation, flow cytometry and cell viability
using fluorescence. Ascitic fluid cells from sarcoma 180 were obtained from Mus musculus peritoneal cavity
and Alpha-terpineol was tested at 100, 250 and 500 μg/mL. Doxorubicin and Cisplatin were used as positive
controls.

Results:

Cytotoxic effects of alpha-terpineol were found in all concentrations tested, reducing cell viability in
50.9; 38.53; 30.82% at 100, 250 and 500 μg/mL, respectively. Alpha-terpineol induced genotoxic effects due to
DNA fragmentation (increased frequency and index of damage), and was clastogenic by increased micronuclei
formation, nucleoplasmic bridges and nuclear buds. DNA fragmentation and increased cell death indicated that
alpha-terpineol can cause early, late, and necrotic apoptosis.

Conclusion:

Our data indicate that alpha-terpineol has antitumor activity revealed by cytogenetic mechanisms and / or loss of cell membrane integrity.

Algae (both micro and macro) have gained huge attention in the recent past for their high
commercial value products. They are the source of various biomolecules of commercial applications
ranging from nutraceuticals to fuels. Phycobiliproteins are one such high-value low volume compounds
that are mainly obtained from micro and macroalgae. In order to tap the bioresource, a significant
amount of work has been carried out for large scale production of algal biomass. However, work
on downstream processing aspects of phycobiliproteins (PBPs) from algae is scarce, especially in the
case of macroalgae. There are many difficulties in cell wall disruption of both micro and macro algae
because of their cell wall structure and compositions. At the same time, there are several challenges in
the purification of phycobiliproteins.

The current review article focuses on the recent developments in downstream processing of phycobiliproteins
(mainly phycocyanins and phycoerythrins) from micro and macroalgae. The current status,
recent advancements and potential technologies (that are under development) are summarised in this
review article besides providing future directions for the present research area.

Published: January 2021

In East Java, the production of clove leaf oil refinement is developed by businesses owned by rural people. The processing operation is simple and start-up investment is low. The clove leaf oil manufacturing procedure uses old leaves that fall naturally in the dry season, these are found to be better preserved, mature and environmentally friendly. East Java rural distillers use a single boiler for steam, water and raw materials in order for the investment costs to remain low. This study aimed to research the use of appropriate technology for the clove leaf distillation process and how to increase clove oil both in yield and quality. Two different tests were conducted; introducing a leaf crusher as a raw material and replace the old chamber material with stainless steel. There are three grades of raw materials; rough leaves, smooth leaves, and non-crushed leaves. After the clove leaves were crushed, they are distilled in the new stainless steel boiler with an aim to compare the oil yield and quality. The result from the crushed leaves treatment indicates there are different volume condensates produced from the same volume of raw materials, 128.2 litres from smooth grade and 117.2 litres from rough grade leaves. The highest percentage of clove oil (15.07%) results from rough grade crushed leaves. By replacing the chamber material with stainless steel positively affects the brightness of the clove oil. In conclusion, these two tests, to improve appropriate technology for clove oil production, can increase both yield and oil brightness, and subsequently improve the competitive advantage and future aspiration of the product.

Published: January 2021

The purpose of this convergent mixed methods study was to explore the feasibility of implementing a chair yoga intervention in assisted living facilities (ALFs), evaluating reach, demand, acceptability, practicality, treatment fidelity, and safety. A yoga intervention was implemented twice a week for eight weeks at four different ALFs. Feasibility data were collected in the form of observational data, reflective field notes, and focus groups. Quantitative and qualitative data strands were compared to determine if results were convergent or divergent. Quantitative benchmarks were met for reach, demand, acceptability, practicality, treatment fidelity, and safety. A directed content analysis revealed qualitative results were convergent with quantitative results. Yoga appears to be feasible, but practicality varied widely and was largely dependent on the resources (i.e., staff support and space) available at individual facilities. Recommendations for future research and practical implications are discussed.
COVID-19 #StayAtHome Restrictions and Deep Vein Thrombosis: Case Report
Authors: Blum Edna , Abdelwahed Youssef S , Spiess Eileen , Mueller-Werdan Ursula , Leistner David M , Rosada Adrian
Published: January 2021

Background

The COVID-19 pandemic triggered countermeasures like #StayAtHome initiatives, which have changed the whole world. Despite the success of such initiatives in limiting the spread of COVID-19 to #FlattenTheCurve, physicians are now confronted with the adverse effects of the current restrictive pandemic management strategies and social distancing measures.

Objective

We aim to draw attention to the particular importance and magnitude of what may be the adverse effects of COVID-19–related policies.

Methods

We herein report a case of an otherwise healthy 84-year-old woman with deep vein thrombosis (DVT) due to COVID-19–related directives. #StayAtHome policies and consequential social isolation have diminished our patient’s social life and reduced her healthy movement behaviors. The patient spent long hours in a seated position while focusing on the intensive flow of media information regarding the pandemic.

Results

Reduced mobility due to preventive social isolation during the COVID-19 pandemic was the only identified cause of the DVT.

Conclusions

While evaluating the effect of the COVID-19 pandemic and governmentally implemented containment measures, including social isolation and mobility reduction, adverse events should be considered. Digital approaches might play a crucial role in supporting public health.

Authors: Ulfah Maria , Suherman Hendra , Laniwati Melia , Makertihartha IGBN , Subagjo Subagjo
Published: January 2021

The effect of acids, bases, zeolite NaA and zeolite NaX impregnation to g-Al2O3 on the catalyst characteristics and activity against methanol dehydration reaction were investigated. The catalyst characteristics include N2 physisorption, X-ray diffraction (XRD), and temperature-programmed desorption of ammonia (NH3-TPD) in addition to catalytic dehydration of methanol performed in a micro fixed-bed reactor at 270°C and 1 atm. The results of XRD characterization showed no changes related to the modification of alumina over acids, bases, and zeolite NaA and zeolite NaX. Therefore, the modification did not have any effect on the crystalline structure of alumina. The textural and surface acidity of g-Al2O3 changed post addition of acids, bases, zeolite NaA and zeolite NaX. NH3-TPD analysis results demonstrated that synthesized g-Al2O3 has three types of acid sites: weak, medium, and strong; however, the weak acid sites were not observed on alumina catalysts modified phosphate, KOH, zeolite NaA, and zeolite NaX. Furthermore, the concentration of strong acid sites increased in the catalyst containing KOH. The catalytic test results showed that the untreated g-Al2O3 catalyst gave prominent activity in dehydration of methanol compared to the treated catalyst following the number and strength of acid sites.

Authors: Isnindar Isnindar , Luliana Sri
Published: January 2021

Buas-buas, meniran, secang, and rosella have biological and pharmacological activities as antioxidants. The combination of the four plants is expected to provide a more potent synergistic effect on antioxidant activity. The purpose of this study was to analyze the total phenol content, total flavonoids, and antioxidant effects before and after combination. The combination of extracts, buas-buas, meniran, secang, and rosella which are used in sequence is (1: 1: 1/2: 1/2), (1: 2: 1/2: 1/2), and (2: 1 : 1/2: 1/2). Plants used in the form of simplicia was extracted by maceration method. Radical capture activity uses DPPH and IC50 values are determined. Determination of total phenol is expressed equivalent to gallic acid. Total flavonoids are expressed as quercetin equivalents. The phenol and flavonoid content obtained are then correlated with antiradical activity. The results showed that the best IC50 values were in the combination of ratios (1: 1: 1/2: 1/2) that is (11.0 µg / mL), then (1: 2: 1/2: 1/2) which was 13.3 µg / mL, and (2: 1: 1/2: 1/2) which is 19.4 µg / mL. The highest total phenolic and flavonoid content in the ratio (1: 2: 1/2: 1/2) is 33.57% w/w EAG and 74.00% w/w EQ. Correlation analysis between IC50 values with total phenolic and flavonoid contents showed a positive correlation with R2 values of 0.8236 and 0.0102 with positive slope. Thus, it can be concluded that the total phenol content influences free radical scavenging activity by 82.36%, while the effect of total flavonoid content was only 1.02%.

Published: January 2021

Alzheimer's disease (AD) is a common chronic neurodegenerative disease with well-defined pathophysiological mechanisms. Ilex kudingcha (IK) C.J. Tseng is commonly known as bitter tea or “Khom” tea in Vietnam. The present study was conducted to investigate the anti-dementia effect of IK using olfactory bulbectomized (OBX) mice. OBX mice were daily treated with IK extract (540 mg/kg) or reference drug, tacrine (2.5 mg/kg) 1 week before and continuously for 3 days after the OBX surgery. The object recognition test, modified Y maze test and fear conditioning test were employed to analyze non-spatial short-term, spatial short-term and long-term memories of the mice respectively. Administration of IK extract and tacrine attenuated these OBX-induced cognitive deficits in mice. The effects of IK and tacrine on spatial short-term memory impairment were reversed by scopolamine, a muscarinic receptor antagonist. The amyloid-beta (Aβ) production in adult transgenic Drosophila brain flies was also investigated by using Western blotting with APP-HA antibody. These results indicated that IK extract improves short-term and long-term memory disturbances in OBX mice and that muscarinic receptor may play a role on these actions. In addition, our result also showed that IK extract reduces the expression of amyloid precursor protein (APP) in brain of AD model using Drosophila melanogaster.

Authors: Hakim Rachman , Haryanto Tri , Sari Dyah Wulan
Published: January 2021

Agriculture is a dominant sector in Indonesia, mostly because many people work in this sector, especially in agricultural centers such as East Java Province. However, it is ironic that the farm sector does not have a considerable contribution to Indonesia's national income. This study aimed to measure rice farming's efficiency in East Java and determine whether education, access to credit, farmer group membership, age, and agricultural extension affected rice farming efficiency. The data source comes from the Central Statistics Agency (Agricultural Business Household Income Survey) in 2013 for East Java Province. The number of samples used was 8603 farmer households. The research method uses Stochastic Frontier Analysis. The results showed that the average efficiency for the Cobb-Douglas production function was 0.764, while the average efficiency for the translog production function was 0.759. The Cobb-Douglas production function is not suitable for this study; the translog production function is considered more appropriate. The variables of education, access to credit, membership of farmer groups, age, and agricultural extension significantly influence rice farming's technical efficiency in East Java. The extension variable has the most significant effect.

OS MORLOCKS NA PERSPECTIVA DE OPRIMIDOS E OS DIÁLOGOS COM A PEDAGOGIA DE PAULO FREIRE
Authors: C. Maciel Neves Cintia , Weschenfelder Gelson , Jung Hildegard Susana
Published: January 2021

Esse texto visa relacionar o retrato de opressão presente em Massacre de Mutantes (Marvel, 1986) com os estudos de Paulo Freire. Comparando o comportamento dos mutantes conhecidos como Morlocks, conseguimos relacioná-los aos oprimidos da obra de Freire. A análise encontrou aproximações entre as obras citadas, pois os X-Men da obra de Freire são os que, por não compartilharem da mesma cultura, ou da mesma situação econômico-educacional, acabam sendo excluídos e oprimidos. Concluímos que nos completamos,aprendemos e crescemos, na diversidade, o que podemos alcançar por meio do diálogo, da problematização e da escuta.
DESDOBRAMENTOS DA FONTE NO MULTIVERSO DA DC COMICS
Authors: Mourilhe Fabio
Published: January 2021

Este trabalho trata de uma educação filosófica que passa pelos quadrinhos. Tem por objetivo geral explicitar a filosofia inerente às histórias em quadrinhos da DC Comics, em especial tratar das implicações do conceito de Fonte. Como problema, temos a introdução de uma fonte primordial para os personagens dos quadrinhos, que ganha uma forte distinção ética e polarização radical, o que leva à utilização de um conteúdo filosófico e metafísico aplicado de forma direta com desdobramentos que se complexificam exageradamente, levando a novos questionamentos sobre sua natureza inicial. Como hipótese, temos que, apesar da divisão inicial dos Novos Deuses de Jack Kirby em polarização radical, existe uma ênfase na fusão entre pólos distintos. O viés suscitado em nossa hipótese ganha mais consistência em Jim Starlin, quando este sugere que a Fonte e a equação antivida fariam parte de um mesmo princípio único. Outras polarizações decorrentes da Fonte, como a contraposição entre Destino sombrio e Justiça também são abordados no trabalho.

Objective: With rising global prevalence
of diabetic retinopathy (DR), automated DR screening is needed for primary care
settings. Two automated artificial intelligence (AI)-based DR screening algorithms
have FDA approval. Several others are under consideration while in clinical use
in other countries, but their real-world performance has not been evaluated
systematically. We compared the performance of seven automated AI-based DR screening algorithms (including one
FDA-approved algorithm) against human graders when analyzing real-world retinal
imaging data.

Research Design
and Methods: This
was a multicenter, non-interventional device validation study evaluating a
total of 311,604 retinal images from 23,724 veterans who presented for
teleretinal DR screening at the Veterans Affairs (VA) Puget Sound Health Care
System (HCS) or Atlanta VA HCS from 2006 to 2018. Five companies provided seven algorithms, including one with FDA
approval, that independently analyzed all scans, regardless of image quality.
The sensitivity/specificity of each algorithm when classifying images as
referable DR or not were compared to original VA teleretinal grades and a
regraded arbitrated dataset. Value per encounter was estimated.

Results: Although high negative
predictive values (82.72%-93.69%) were observed, sensitivities varied widely
(50.98%-85.90%). Most algorithms performed no better than humans against the
arbitrated dataset, but two achieved higher sensitivities and one yielded
comparable sensitivity (80.47%, p = 0.441) and specificity (81.28%, p = 0.195).
Notably, one had lower sensitivity (74.42%) for proliferative DR (p = 9.77x10-4)
than the VA teleretinal graders. Value per encounter varied at $15.14-$18.06
for ophthalmologists and $7.74-$9.24 for optometrists.

Conclusions: The DR screening algorithms showed significant
performance differences. These results argue for rigorous testing of all such
algorithms on real-world data before clinical implementation.

Published: January 2021

Bu çalışmada, bir saha betonuna taze halde iken farklı sürelerde vakum ile beton karışım suyunun geri çekilme işlemi uygulanmıştır. Taze betona vakum uygulama işlemiyle, beton içerisindeki karışım suyunun bir kısmı ve ayrıca hapsolmuş hava da kontrollü olarak alınmıştır. 15 cm kalınlığında olacak şekilde üretilen beton bloklar 3 gruba ayrılmıştır. Bunlardan vakum uygulanmayan beton blok “A” (şahit), 17 dakika vakum uygulanmış beton blok “B”, 35 dakika vakum uygulanmış beton blok da “C” olarak gruplandırılmıştır. Ankara’da 66 ay açık hava şartlarına maruz kalan vakumlu beton bloklardan 75mm çapında ve 150 mm yüksekliğinde karot numuneleri alınmıştır. Beton derinliğine bağlı olarak vakum etkisinin betonun özelliklerindeki değişimlerini gözlemleyebilmek amacı ile alınan karot numuneleri 50 mm yükseklikte olacak şekilde alt, orta ve üst olmak üzere 3 eşit parçaya bölünmüştür. Bu numuneler üzerinde yapılacak deneysel çalışmalarla vakumlama süresinin betonun farklı derinliğindeki basınç dayanımı, aşınma direnci ve kapiler su emme etkisi araştırılmıştır. Çalışmanın sonucunda, şahit betonunun üst yüzeyinden uzaklaştıkça şahit betonun basınç dayanımı ve aşınma direncinin arttığı, kapiler su emme miktarının azaldığı ve kapilerite katsayısının küçüldüğü gözlemlenmiştir. Ayrıca, vakum uygulanan yüzeyden uzaklaştıkça betonun basınç dayanımının ve aşınma direncinin azaldığı, kapiler su emme miktarının arttığı ve kapilerite katsayısının da büyüdüğü gözlemlenmiştir.

Previous research has shown that some compounds in leaves and seeds of sugar apple have a cytotoxic activity. The aim of this research was to determine the cytotoxicity of semipolar fraction of ethanolic extract from sugar apple stem bark (Annona squamosa L.) on T47D cancer cells. The semipolar fraction of ethanolic extract from sugar apple stem bark was collected by fractionation using Vacuum Liquid Chromatography (VLC) with hexane:ethyl acetic (9:1, 8:2, 7:3, and  6:4)  as  mobile  phase.  Cytotoxicity from the fractions of five different concentration namely; 25, 50, 100, 150, and 250, µg/mL was measured by MTT assay. The potency of the cytotoxicity was defined by the ability of the fraction to inhibit the growth of T47D cells indicated by the value of IC50. Qualitative analysis of contained compounds in the fraction was done by Thin Layer Chromatography (TLC) method using silica gel F 254 as a stationary phase and hexane:ethyl acetic (7:3) as a mobile phase. UV 254 and 366 nm lamp also Dragendorff, citroboric, and FeCl3 spray reagents were used to visualize the spots of the secondary metabolites. The result proved that the semipolar fraction of ethanolic extract from sugar apple stem bark showed potential cytotoxicity on T47D cancer cells with IC50value of 70,77 µg/mL. Qualitative analysis showed that the fraction contained flavonoids and alkaloids which is presumably responsible for its cytotoxic activity.
A Balaton üledékének ásványai
Authors: Pósfai Mihály
Published: January 2021

A Balaton holocén üledékének tudományos kutatása közel 130 éve kezdődött. Az üledék felhalmozódásának törvényszerűségeit, az iszap összetételét, a tavi tápanyagforgalomban töltött szerepét a 20. század második felében viszonylag alaposan megismertük. Ennek ellenére a mai, modern geokémiai és ásványtani módszerekkel végzett vizsgálatok mindig újabb érdekes részletekkel gazdagítják ismereteinket. A jelen összefoglalásban elsősorban a tavi karbonátképződés jellegzetességeit, az agyagásványok kalcitképződésben játszott szerepét, valamint a biológiai folyamatok révén képződő ásványok egyes csoportjait tárgyalom. Jelenleg is több irányú, intenzív kutatás folyik egyrészt a Balatonban lejátszódó ásványképző folyamatok, másrészt az iszap ásványai és a tavi tápanyag (elsősorban a foszfor) mobilitása közötti összefüggések megértése érdekében.
Szemelvények az elmúlt két évtized ELTE-n végzett, medenceléptékű hidrogeológiai kutatásaiból
Authors: Czauner Brigitta , Mádlné Szőnyi Judit
Published: January 2021

Az Eötvös Loránd Tudományegyetem (ELTE) Általános és Alkalmazott Földtani Tanszékének hidrogeológiai kutató és oktatócsoportja (Tóth József és Erzsébet Hidrogeológia Professzúra) tevékenységének középpontjában a felszínalatti vízáramlásoknak és kapcsolódó jelenségeknek a hidraulikus folytonosság alaptételére épülő medenceléptékű és rendszer szemléletű megközelítése áll. A jelen tanulmány e megközelítést történeti felvezetéssel és a korábbi, rétegtani (hidrosztratigráfiai) alapú „artézi” paradigmával szembeállítva mutatja be. A folyamatosan fejlesztett medenceléptékű hidrogeológiai kutatási módszertant röviden tárgyaljuk, a technikai részletek helyett kiemelve az alkalmazott módszertani megközelítések magyarázatát. Ezek közül legnagyobb jelentőséggel a kutakban mérhető hidraulikai adatok medenceléptékű, azaz medencehidraulikai elemzése bír, amelynek eredménye a „valós vízáramlási rendszermodell” felállítása. Ennek megfelelően kutatás történetünkből a medenceléptékű és különösen a medencehidraulikai eredményeket szemlézzük a továbbiakban, említve az ezekáltal összefüggésrendszerbe helyezett és egyéb módszerekkel vizsgált jelenségeket is. Az ország területének nagyrészét lefedő kutatásaink domborzattól és kőzettípustól (sziliciklasztos vagy karbonátos) függetlenül kimutatták a kőzetváz hidraulikus folytonosságát és a gravitáció vezérelte regionális felszínalatti vízáramlási rendszerek jelenlétét. Ezek medenceléptékben fedetlen, csapadékvízből utánpótlódó és közel hidrosztatikus nyomásrezsimű tartománya alatt a mélymedencékben abnormális nyomásrezsimek (túlnyomásos vagy alulnyomásos) fedett, és nem vagy csak korlátozottan utánpótlódó tartományai találhatók. E komplex hidraulikai helyzettel és a felszínalatti víz áramlások földtani és környezeti hatótényező szerepével számos felszíni (szikesedés, felszín alatti víztől függő ökoszisztémák, FAVÖKO-k stb.), és felszín alatti (hipogénbarlangképződés, szénhidrogén csapdázódás stb.) jelenség és folyamat nyert magyarázatot.
Populistiset miesjohtajat ja performatiivisuus: Timo Soinin, Hugo Chávezin ja Donald J. Trumpin hahmot journalistisissa kuvissa
Authors: Salojärvi Virpi
Published: January 2021

Tässä artikkelissa tarkastellaan, miten populististen liikkeiden miesjohtajien hahmot rakentuvat mediassa, esimerkkeinä Perussuomalaisten perustaja ja pitkäaikainen puheenjohtaja Timo Soini, Yhdysvaltain presidentti Donald J. Trump ja Venezuelan edesmennyt presidentti Hugo Chávez. Populismi käsitetään tässä retoris-performatiivisena prosessina laclaulaiseen teoriaan nojaavan populismitutkimuksen suuntauksen mukaisesti. Vaikka keskeinen osa näiden johtajien populistista viestiä välittyy sanallisesti, myös heidän habituksensa ja visuaaliset performatiiviset elementit – mukaan lukien kehonkieli, persoona, tilankäyttö ja pukeutuminen – täydentävät ja ennen kaikkea alleviivaavat heidän sanomaansa luoden mielikuvaa poliittisesta eliitistä poikkeavasta johtajasta, jolla on erityinen suhde kansaan. Keskeisiä performatiivisia elementtejä populististen johtajien representaatiossa ovat autenttisuus ja kansallisen kontekstin luomat erot emotionaalisen suhteen luomisessa kansan ja johtajan välille sekä maskuliinisuuden esitykset, joita artikkelissa tarkastellaan yhdistämällä teatterin tutkimusta (Goffman 1956) ja sosiaalisten performanssien tutkimusta (Alexander 2004) laclaulaiseen populismin tutkimukseen.
