Published: February 2021

Hepatitis A, an acute type of hepatitis caused by the hepatitis A virus, occurs worldwide. Following the 2009 hepatitis A epidemic in South Korea, patient outbreak reports were collectively converted to an “all-patient report” in 2011, and national immunization programs were introduced for children in 2015. In this study, we aimed to analyze the changes and characteristics of hepatitis A antibody titers in South Korea following the epidemic. The results of hepatitis A antibody tests performed at clinical laboratories from 2009 to 2019 were analyzed based on year, age, region, sex, and medical institution. The average 2009–2018 positive anti-hepatitis A virus immunoglobulin G rate was 51.8%, but it increased (56.06%) in 2019. Significantly different antibody-positive rates were observed based on age: <10 years, 54.5%; 20–29 years, 19.5%; ≥50 years, almost 100%. The positive rate of individuals in their teens and 20s gradually increased, whereas that of those in their 30s and 40s gradually decreased. Males had higher antibody-positive rates than females, and samples from higher-level general hospitals exhibited higher antibody rates. The positive anti-hepatitis A virus immunoglobulin M rates gradually decreased after 2009 and were <1% after 2012. However, a high positive rate of 3.69% was observed in 2019 when there was an epidemic. Anti-hepatitis A virus immunoglobulin G-positive rates were similar throughout the year, but the anti-hepatitis A virus immunoglobulin M-positive rates increased from January, peaked in April, and decreased from July, exhibiting distinct seasonality. This is considered to be related to groundwater pollution during the spring drought season. The introduction of the “all-patient report” and national vaccination program for children has had an effective influence on hepatitis A management. However, for hepatitis A prevention, policy considerations for high-risk age groups with low antibody-positive rates will be necessary.
An overview of the characteristics and quality assessment criteria in systematic review of pharmacoeconomics
Authors: Min Chen , Xue Mi , Haotian Fei , Jialian Li , Lingli Zhang
Published: February 2021

Background

The systematic review of economic evaluations plays a critical role in making well-informed decisions about competing healthcare interventions. The quality of these systematic reviews varies due to the lack of internationally recognized methodological evaluation standards.

Methods

Nine English and Chinese databases including the Cochrane Library, PubMed, EMbase (Ovid), NHS economic evaluation database (NHSEED) (Ovid), Health Technology Assessment (HTA) database, Chinese National Knowledge Infrastructure (CNKI), WangFang, VIP Chinese Science & Technology Periodicals (VIP) and Chinese Biomedical Literature Database (CBM) were searched. Two reviewers independently screened studies and extracted data. The methodological quality of the literature was measured with modified AMSTAR. Data were narrative synthesized.

Results

165 systematic reviews were included. The overall methodological quality of the literature was moderate according to the AMSTAR scale. In these articles, thirteen quality assessment tools and 32 author self-defined criteria were used. The three most widely used tools were the Drummond checklist (19.4%), the BMJ checklist (15.8%), the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) statement (12.7%). Others included the Quality of Health Economic Studies (QHES), the Consensus on Health Economic Criteria (CHEC), the checklist of Center for Reviews and Dissemination (CRD), the Philips checklist, the World Health Organization (WHO) checklist, the checklist of Critical Appraisal Skills Program (CASP), the Pediatric Quality Appraisal Questionnaire (PQAQ), the Joanna Briggs Institute (JBI) checklist, Spanish and Chinese guidelines. The quantitative scales used in these literature were the QHES and PQAQ.

Conclusions

Evidence showed that pharmacoeconomic systematic reviews’ methodology remained to be improved, and the quality assessment criteria were gradually unified. Multiple scales can be used in combination to evaluate the quality of economic research in different settings and types.
A robust pooled testing approach to expand COVID-19 screening capacity
Authors: Bish Douglas R. , Bish Ebru K. , El-Hajj Hussein , Aprahamian Hrayer
Published: February 2021

Limited testing capacity for COVID-19 has hampered the pandemic response. Pooling is a testing method wherein samples from specimens (e.g., swabs) from multiple subjects are combined into a pool and screened with a single test. If the pool tests positive, then new samples from the collected specimens are individually tested, while if the pool tests negative, the subjects are classified as negative for the disease. Pooling can substantially expand COVID-19 testing capacity and throughput, without requiring additional resources. We develop a mathematical model to determine the best pool size for different risk groups, based on each group’s estimated COVID-19 prevalence. Our approach takes into consideration the sensitivity and specificity of the test, and a dynamic and uncertain prevalence, and provides a robust pool size for each group. For practical relevance, we also develop a companion COVID-19 pooling design tool (through a spread sheet). To demonstrate the potential value of pooling, we study COVID-19 screening using testing data from Iceland for the period, February-28-2020 to June-14-2020, for subjects stratified into high- and low-risk groups. We implement the robust pooling strategy within a sequential framework, which updates pool sizes each week, for each risk group, based on prior week’s testing data. Robust pooling reduces the number of tests, over individual testing, by 88.5% to 90.2%, and 54.2% to 61.9%, respectively, for the low-risk and high-risk groups (based on test sensitivity values in the range [0.71, 0.98] as reported in the literature). This results in much shorter times, on average, to get the test results compared to individual testing (due to the higher testing throughput), and also allows for expanded screening to cover more individuals. Thus, robust pooling can potentially be a valuable strategy for COVID-19 screening.
Walking the city: Handshake 302 and reinventing public art in Shenzhen
Authors: Wang Meiqin
Published: February 2021

This article analyses the practice of Handshake 302, an art collective based in Shenzhen, as an exemplary case of the recent development of urban public art in China in which public participation has become central. Defining itself as an experimental public art project, Handshake 302 adopts an interdisciplinary, open-ended, collaborative and socially conscious approach in designing its various participatory tactics. Advocating that ‘art should belong to everyone who contributes to the city’, it has charged itself with the task of creating opportunities to enable people of disparate backgrounds ‘to participate in art activities and unleash their creativity’. In practice, it embraces a wide range of forms/ methods to engage urban residents of Shenzhen, involving them in art making, exhibitions, research, workshops, dialogues, tours and field trips, among others, with the mission of enabling ordinary people to engage with creative activities that deal with Shenzhen’s diverse urban spaces. Discussing key programmes carried out by Handshake 302, I posit that urban public art has become an expanded field for critically minded art professionals to initiate grassroots urban interventions and social innovations and the working of this art collective sheds light on this new artistic and civic movement that can be called socially engaged participatory public art.
A survey for potentially zoonotic parasites in backyard pigs in the Bucaramanga metropolitan area, Northeast Colombia
Authors: Pinilla Juan Carlos , Morales Elsa , Florez Muñoz Angel Alberto
Published: February 2021

Background and Aim: Backyard pigs farming is a rearing system associated with poor hygienic and sanitary conditions of the pig, often causing public health and food safety problems. Therefore, this study was conducted to investigate the occurrence of potentially zoonotic parasites in population pig reared under backyard farming in the Bucaramanga metropolitan area, Northeast Colombia.

Materials and Methods: From September to December 2019, a total of 558 fecal samples from 64 backyard pig farms were examined for the presence of enteric protozoan infection. The coprological diagnosis was done by direct examination using Lugol's iodine solution, buffered saline solution, and Kinyoun technique. In addition, blood samples were collected from 200 pigs. Serum was collected and used for the detection of Trichinella spiralis and Taenia solium cysticercosis infections, using the enzyme-linked immunosorbent assay.

Results: The overall prevalence of zoonotic protozoa in the Bucaramanga metropolitan area was 65.2%, reporting 52.7% prevalence for Balantidium coli, 33.7% for Entamoeba coli, and 5.7% for Cryptosporidium spp. Regarding the prevalence by municipalities, there was no statistical association (p>0.05), indicating that the prevalence was similar in the region under study. Pigs >7 months of age showed to be a risk factor for B. coli infection, indicating that the prevalence increases with the age, while pigs raised at >1000 masl and access to latrines, increased infection risk for E. coli and Cryptosporidium spp. infections. In the present study, T. spiralis infection was not detected in the analyzed sera, while T. solium cysticercosis infection was found to be 40.5%.

Conclusion: The high prevalence of protozoan infections and porcine cysticercosis reported in this study could be due to poor facilities, and lack of hygiene in the facilities, and suggests the possible transmission of these parasite populations between pigs and humans, thus increasing the transmission of parasites zoonotic potential. Therefore, appropriate sanitary management practices and deworming programs should be adopted to reduce the prevalence of these infectious agents.

The Effectiveness of Armoured Vehicles in Urban Warfare Conditions
Authors: Öğünç Gökhan İbrahim
Published: February 2021

Since the Second World War, the major armed conflicts have been occurred in or in the vicinity of the urban areas rather than rural areas, amongst conventional armies and armed groups or terrorists/insurgents. The architectural and construction characteristics of the urban area increase the opportunities for armed groups to ambush, easily escape, conceal, relocate and attack. Additionally, the narrow streets, the blocked roads by the debris of buildings, and IED threats make the urban areas one of the most dangerous conditions for infantries and armoured vehicles. The majority of present armoured combat vehicle types due to the limited visibility, low manoeuvre capability, and limited firing power, they are insufficient for performing the standalone operation without infantry forces and combat engineer support in urban warfare conditions. In this study, 13.400 data belonging to 676 attacks towards armoured vehicles during the counter-terrorism operations against PKK/PYD and ISIS in the urban areas were analysed within the perspective of forensic science techniques such as forensic ballistics and shooting reconstruction. According to the examinations and analyses carried out within the scope of this study; the leading critical features that an armoured combat vehicle that will operate in the urban areas may be listed under five general headings: Structure, Ballistic Protection and Armour, Self Defence and Weapon Systems, Situational/peripheral Awareness and C4I2 Systems and Integrated Warfare Systems.

Obce odpowiedniki haseł niemieckich w niemiecko-polskich słownikach Krzysztofa Celestyna Mrongowiusza
Authors: Nowowiejski Bogusław
Published: February 2021

The analysis of only a part of lexis/vocabulary of foreign origin registered in a Polish part of the Mrongoviusz German-Polish dictionary from the middle of the XIX century (letters: G, L, Z) proves that already at that time Polish language vocabulary was international to a great extent. Moreover, it further proves that despite easy assimilation of borrowings from various sources into a Polish language, their presence in Polish speech is in many cases temporary. Vocabulary richness of the Mrongoviusz dictionary is an argument sufficient to prove that bilingual dictionaries from different epochs of Polish language development are an interesting subject of historical and linguistic research.
Stałe połączenia wyrazowe oznaczające proces umierania w języku polskim i włoskim
Authors: Szerszunowicz Joanna
Published: February 2021

The paper discusses fixed units, raging from non-idiomatic phraseological units to idioms, naming death in Polish and Italian. Two corpora of word combinations have been excerpted from lexicographic works in order to conduct the analysis covering the following aspect: motivation, stylistics, axiology, semantics with a special focus on specifying function of the units, equivalence. The stylistics of the units vary greatly, since their functions range from elevation of the death to its depreciating, which results from the fact that word combinations perform a variety of psychological functions. The vast majority of the word combinatio ns excerpted appear in both languages, since either they are of Christian, especially biblical, or mythological origins. Other units belonging to the group are those reflecting common observations of the process of dying as well as the funeral culture. Therefore, the idioms belonging to the group are word combinations of a high degree of translatability. In many cases such idioms appear not only in Polish and Italian, but in other languages as well,, since they are of international character. However, there are units appearing only in one of the languages, i.e. either Polish or Italian. Some of them are products of metaphorical thinking specific to the nation, others base on word play. Moreover, certain idioms have a cultural motivation of national character, for instance they refer to the element of reality important only in a given culture or the key component is a proper name of national importance.

Published: February 2021

El Método Mexicano de Ordenación de Bosques Irregulares (MMOBI) es el sistema de gestión forestal de cubierta forestal continua empleado habitualmente en el estado de Durango (México). La selvicultura que se aplica en el MMOBI consiste en cortas de selección individual (o entresaca árbol a árbol), buscando una distribución diamétrica en forma de J invertida. En este trabajo se analiza la aplicación del MMOBI en las masas naturales mixtas de Asturias (norte de España) representadas en los estratos números 4 y 9 del Tercer Inventario Forestal Nacional, formados mayoritariamente por frondosas caducifolias. Se ha calculado para cada género la distribución diamétrica real y se ha estimado la ideal según el MMOBI. El porcentaje de intensidad de corta (IC%) fue generalmente bajo en el estrato 4, siendo inferior al 20% en la mayoría de los géneros excepto en Fraxinus y Acer con IC >50%. En el estrato 9 la IC% fue generalmente más alta que en el estrato 4, aunque también fue de baja a intermedia, excepto para el género Tilia con IC >50%, cuyos árboles se suelen incluir en el Green Tree Retention.El MMOBI se presenta como una alternativa de gestión para masas con un carácter preferente protector.
Avaliação do estado nutricional da mangueira Tommy Atkins no submédio do vale do rio São Francisco: cálculo dos índices DRIS

Published: February 2021

O Sistema Integrado de Diagnose e Recomendação, DRIS, é uma ferramenta importante na avaliação do estado nutricional das plantas. Os objetivos do presente trabalho foram avaliar o estado nutricional de pomares de mangueira Tommy Atkins no Submédio do vale do São Francisco, no Brasil, mediante o DRIS, relacionar os índices com os teores foliares de nutrientes e discriminar a ordem de limitação de cada nutriente nas subamostras de alta e de baixa produtividade. Foram amostrados sessenta e três pomares comerciais com sete ou mais anos de idade. Com os teores foliares de macro e micronutrientes foram calculados os índices DRIS, utilizando-se como referência os dados da subpopulação de alta produtividade. Os maiores valores de Índices de Balanço Nutricional médio (IBNm) verificados em pomares de baixa produtividade demonstraram o potencial deste índice na avaliação do estado nutricional da mangueira, e a necessidade de adubações mais criteriosas em tais pomares. A utilização do conceito de potencial de resposta à adubação na interpretação dos índices DRIS mostrou-se uma ferramenta eficaz, principalmente nos pomares de baixa produtividade, onde os desequilíbrios nutricionais foram maiores, confirmando a seqüência de deficiência a excessos, auxiliando o diagnóstico final, indicando os nutrientes que realmente estão em deficiência ou em excesso.
Estudio de la capacidad germinativa de Arnica montana L. en Galicia

Published: February 2021

Se realiza un estudio preliminar de la capacidad de germinación y el tiempo de emergencia de las semillas de Arnica montana procedentes de 11 poblaciones situadas en las provincias de Lugo y Ourense (Galicia). Además, se han comparado dos métodos para estimular la germinación de las semillas: humectación con nitrato potásico y con agua. Los resultados muestran importantes diferencias entre localidades en cuanto a la proporción de semillas germinadas (variaciones entre el 8% y el 96%) y al tiempo de emergencia. Sin embargo, el tratamiento pregerminativo con nitrato potásico no ofrece mejores resultados que la humectación con agua exclusivamente. Estos resultados no guardan relación con aspectos ambientales (altitud, tipo de hábitat) ni el tamaño muestral o poblacional de la especie estudiada en cada localidad e inducen a pensar que la viabilidad de las poblaciones naturales de árnica estudiadas puede estar condicionada por aspectos locales (clima, disponibilidad de polinizadores) que intervengan en los procesos de reproducción sexual. Los resultados aquí obtenidos deberían tenerse en cuenta de cara a la gestión futura del aprovechamiento sostenible de esta especie.

A região não dispõe de um conjunto de normas de diagnose de tecidos foliares para o cultivo, sendo o diagnóstico do estado nutricional e as recomendações de fertilização baseados em faixas de teores de nutrientes em folhas de mangueira cultivadas em diferentes regiões. Foram coletadas amostras de folhas para análise química, antes da aplicação de quebradores de dormência de brotos. As normas DRIS para nutrição das plantas foram estabelecidas com base em um banco de dados criado nesta pesquisa, envolvendo os nutrientes N, P, K, Ca, Mg, B, Cu, Fe, Mn e Zn. Essas normas foram estabelecidas considerando uma subpopulação de plantas com produção igual ou superior a 250 kg/planta, produção essa representativa para as condições ambientais da principal zona produtora de manga do país. Das noventa relações consideradas entre nutrientes, sessenta e duas foram significativas pelo teste F, das quais, quarenta e quatro foram selecionadas como normas para a cultura.

Las secuencias polínicas, y en concreto las obtenidas a partir de sedimentos limnéticos, se han revelado como la herramienta más eficaz a la hora de valorar los cambios climáticos cuaternarios a nivel regional y su incidencia sobre los ecosistemas. Una parte importante de los registros obtenidos en el NW ibérico, presenta una antigüedad menor de 3.000; las secuencias continuas de más de 6.000 años, que alcanzan cronologías de 10.000 o 12.000 años, se limita a grandes turberas de zonas de montaña; finalmente, los periodos de más de 17.000 años, únicamente aparecen representados en sedimentos fosilizados, en los que se han obtenido registros continuos de 10.000 o 20.000 años y excepcionalmente periodos de más de 50.000. Las más de 200 secuencias disponibles para el NW ibérico, permiten realizar una correcta evaluación de la incidencia de los cambios climáticos y de la influencia antrópica sobre los ecosistemas, a lo largo de los últimos 100.000 años. La abundancia de datos, accede a reconocer la diferente influencia de estos cambios sobre las distintas áreas biogeográficas del territorio.
Desarrollo y acumulación de Ulva spp. en la costa de la Bretaña francesa: por una necesaria reorientación de las investigaciones

Durante décadas, las investigaciones desarrolladas sobre la proliferación de Ulva en Bretaña han postulado la hipótesis de que los flujos de nitrógeno vertidos al mar por los cursos de agua en el mes de junio son los responsables del desarrollo de estas algas; y que por lo tanto su reducción durante la primavera constituye el principal medio de control. Los Programas de Acción implantados asumen esta hipótesis, así como los modelos que la integran. La drástica reducción de aportes de nitrógeno que se plantea, además de inalcanzable y probablemente ineficaz, parece poco consistente. Se revisan aquí los argumentos que cuestionan este postulado y se propone el desarrollo de nuevas investigaciones, a fin de obtener los suficientes datos fiables que permitan profundizar en la ecología de este fenómeno.

The general objective of this article is to contextualize Psychodrama in the online psychotherapeutic intervention model, and the specific objective is to demonstrate the viability of online psychodramatic care with adults from the description of sociatric sessions through this modality. The psychodramatic resources used in the highlighted sociatric sessions are Dramatic Games, Internal Psychodrama, Relationship Psychotherapy and Bipersonal Psychodrama with dramatization in an open scene. The results obtained confirm that Psychodrama breaks the need for face-to-face psychotherapy for sociatrics to occur, opening space for new paths.

El proyecto Efectos del concepto de valor razonable en las entidades públicas en Colombia pretende efectuar una aproximación conceptual al valor razonable tomando de referencia los avances académicos y normativos en esta temática, posteriormente se plasmará un estudio multicaso el cual tiene por objetivo evidenciar los efectos de la aplicación del valor razonable en entidades públicas, para ejecutar lo anterior se tiene previsto analizar tres tipos de entidades: i) Empresas que cotizan en el mercado de valores, o que captan o administran ahorro del público; ii) empresas que no cotizan en el mercado de valores, y que no captan o administran ahorro del público y iii) entidades de gobierno1 . Se decide realizar el estudio multicaso de acuerdo con los tres modelos normativos contables públicos en Colombia, el análisis implica desde la revisión documental del proceso de aplicación del valor razonable hasta entrevistas a profundidad de directivos o contadores de cada una de las entidades. El proyecto parte de la hipótesis que la aplicación del valor razonable en estas entidades presenta dificultades de medición, altos costos y además, genera impactos financieros, se desarrolla desde un enfoque principalmente cualitativo; sin embargo, para cumplir con los objetivos propuestos una parte del análisis toma de referencia la información financiera cuantitativa de las entidades por lo cual es mixto.
El imaginario social del emigrante retornado en la política migratoria colombiana
Authors: Felipe Aliaga Sáe
Published: February 2021

Este texto forma parte del proyecto: “Imaginarios del retorno a Colombia posconflicto. Posibles escenarios a partir del discurso de refugiados colombianos en Ecuador y en las políticas para el retorno” 1 . Proyecto aprobado por la Vicerrectoría Académica General de la Universidad Santo Tomás-Colombia en la décima convocatoria FODEIN 2016 (Fomento, Desarrollo y Producción de Investigación de Alto Nivel en la Universidad Santo Tomás). El proyecto aborda el hecho de que en Colombia el conflicto armado y la violencia han producido una alta migración forzada, millones de personas desplazadas internamente y cientos de miles han cruzado las fronteras para salir de Colombia. Ecuador registra el mayor número de refugiados colombianos, existiendo situaciones problemáticas que pueden impulsar a que estos busquen movilizarse a otro destino o regresar al país. De esta manera, las políticas para el retorno deben jugar un papel importante en facilitar este proceso.

1. Comité Ejecutivo Ampliado RCP: La Universidad Santo Tomás, como Coordinadora Suplente del Nodo Centro, fue invitada para revisar, en Compañía del Comité Ejecutivo, el informe que se presentaría en la Asamblea General, con el objetivo de llegar a acuerdos previos en las propuestas de líneas para la definición del Plan de Acción 2016-2017, a partir de los trabajos que se han venido adelantando al interior de los Nodos. 2. Relación entre las IES y la Empresa: transferencia de conocimiento: Se da inicio al encuentro académico con un conversatorio dirigido por la Dra. Ana Lucía Pérez Patiño, Directora del programa de gestión tecnológica, ciencia y tecnología, de la U. de Antioquia, y con el Dr. Juan Casado Canales, Secretario General de la Consejería de Educación de la Junta de Castilla y León (España). La discusión giró en torno a los siguientes puntos: La Universidad se constituye alrededor de tres funciones universitarias: Transmisión del conocimiento (Docencia) Generar conocimientos (Investigación) Transferencia de conocimiento (responsabilidad social) Siendo la transmisión de conocimientos la función que más la caracteriza y la Generación lo que más busca, porque se presenta más dificultad al momento de transferir el conocimiento, sobre todo por la diferencia del lenguaje: los desarrollos que se alcanzan al interior de las IES responden a un lenguaje y procedimientos académicos que, en muchas ocasiones son ajenos a los que son manejados en otros contextos, Por ejemplo, los doctores se forman para la docencia, o para los ambientes universitarios, porque culturalmente no hay muchas probabilidades de que una empresa contrate a un PHD recién graduado. Entonces, ¿cómo lograr un cambio?
Reproducción de Ulmus glabra Huds. en la región de procedencia 20: Sierra de Guadarrama-Ayllón
Authors: Colmenero Martín Isidoro , Martínez García Felipe
Published: February 2021

Las poblaciones de Ulmus glabra Huds. en el Sistema Central de España se encuentran amenazadas. Varios estudios informan que la especie en esta área se encuentra cerca de la extinción.
El objetivo de este proyecto es estudiar la reproducción ex situ de Ulmus glabra en vivero con el objetivo de conseguir el material vegetal necesario para ejecutar planes de conservación mediante los siguientes objetivos parciales:
1.- Desarrollo de un protocolo para la producción de clones mediante reproducción vegetativa, estableciendo las técnicas que proporcionen los mejores resultados de enraizamiento.
2.- Análisis de la capacidad de reproducción sexual y viabilidad de las semillas.
Se tomaron muestras de 49 árboles de 9 poblaciones diferentes y se estudió la influencia de 3 factores en el éxito del enraizamiento, concluyendo que solo el uso de ácido indolbutírico fue estadísticamente diferente al resto.
Las semillas viables de olmo de montaña son muy raras, pero contrariamente a informes anteriores se conservan fácilmente e incluso mantienen su capacidad de germinación durante al menos un año en condiciones de cultivo de vivero al aire libre (calor, frío y humedad alta).

The pods of Acacia nilotica were successfully utilized for the extraction of tannins using a methanol/water extraction medium. The experimental design employed for the extraction was a central composite design that enabled the evaluation of the effects of time, temperature, and methanol concentration on the dependent variables of extraction yield, total phenolic contents (TPC, as gallic acid equivalents (GAE)), and antioxidant activity (AA, as millimoles of ascorbic acid equivalents (AAE)). Response surface models were developed for the three responses, and statistical analysis of variance was performed to determine the optimum values of the independent variables and the coefficients of determination. The maximum extraction yield of 46.2 wt% (pod extract) was achieved at 200 min, 85 °C, and 40% methanol concentration. Similar conditions also led to the attainment of 50.7 wt% TPC and 51.3 mmol AAE/100 g pod. The coefficients of determinations were 0.9750 for extraction yield, 0.9626 for TPC, and 0.9774 for AA, which indicated that the model equations obtained fitted the experimental data. The result of the retanning of the leather using the extracted A. nilotica tannins also showed that the tear and tensile strength, as well as the elongation at break, of the leather samples were within the range obtained when chestnut extract and chrome tannin were used.
Brexit: lessons learned, status quo and way ahead
Authors: Okinčic Sebastjan
Published: February 2021

On 23 June 2016 almost 17.5 million citizens of the United Kingdom voted to leave the European Union. The UK government invoked the relevant Article 50 of the Treaty on European Union on 29 March 2017. As authors of the said provision have admitted, it was never to be used (Fabbrini, 2017). And yet here we all are/were (depending on when you are reading it), anno domini 2020, witnessing an unprecedented event of a sovereign state “taking back control” i.e. leaving in great pain the most powerful economic and political union of sovereign states ever established, taking advantage of the procedure that had initially not only been de iure impossible, but also seemed inconceivable in and of itself.According to Theresa May, “Brexit means Brexit”. Little help did that tautological definition bring anyone. And yet, after Brexit came, the transition period started. Written in the middle of the said transition period, the purpose of this paper is to briefly treat on Brexit in general and the near-term future related thereto. In addition, also considering the timing of this paper, i.e. May / June 2020, a particular regard will be paid to the more distant future ahead of us – certain matters pertaining to international commercial dispute resolution after Brexit.Considering the overall uncertainty surrounding Brexit that we find ourselves in, the relevance of the topic discussed in the paper is unquestionable. In addition, relevance-wise, one could consider whether the process we are all witnessing could result in encouraging or, rather, discouraging any similar future initiatives. In this context, a broader perspective will be utilised to come to certain indicative conclusions as to whether Brexit can result in good know-how practices learned for future similar initiatives, or rather serve as an example for “never again”.
