The paper proposes the comparative evaluation of sequential and parallel methods for identifying measurements of nearby objects. The problem statement is choosing the method for identifying measurements of nearby objects. The decision rule for identifying the results of radio engineering measurements of the coordinates of objects is obtained. The decision rules for identifying objects by sequential and parallel methods under various conditions are obtained. The cases of absence and presence of false marks from nearby objects are considered. The task of choosing serial or parallel methods for identifying measurements from nearby objects was set. The comparative evaluation of serial and parallel measurement identification methods is provided. As an indicator of the effectiveness of the methods, we chosen the probability of identification error. We estimated the probability of identification error depending on the relative average distance between objects in the absence of false measurements and in their presence. It is determined that the probability of an identification error when using the parallel identification method is less than when using the sequential identification method. This gain increases as the average relative distance between objects decreases. Based on the analysis of methods for identifying measurement results, it was found that the most appropriate identification method is a parallel method for identifying measurement results. The efficiency of the method increases with decreasing relative average distance between objects. Keywords— evaluation, sequential method, parallel Method, identification, measurement, nearby object, hypothesis

El objetivo del estudio fue cuantificar e interpretar los indicadores y significados de la autopercepción de salud de los docentes de un Instituto Superior Tecnológico. El alcance fue descriptivo, correlacional y explicativo con enfoque mixto derivativo CUANTI – cuali. La parte cuantitativa tuvo un diseño no experimental, descriptivo y correlacional. A 106 docentes se les aplicó el cuestionario de Salud General de Goldberg GHQ-30, se analizaron los resultados de sus variables asociándolos con datos nominales a través de la Chi cuadrada X2, V de crammer y la razón de momios para determinar relaciones estadísticamente significativas, fuerza inferencial y probabilidad de ocurrencia. La fase cualitativa se desarrolló a través de la entrevista focal con muestreo propositivo, los ejes temáticos fueron las mismas dimensiones del cuestionario de Goldberg. El método de análisis fue de contenido temático. Como principales resultados: 39 docentes presentaron perturbaciones en salud mental: síntomas psicosomáticos: 23,6%, ansiedad e insomnio: 12,3%, disfunción social: 4,7% y depresión: 0,9%. Las mujeres y los docentes de la carrera de Gestión Ambiental resultaron ser grupos vulnerables a síntomas psicosomáticos con escores de OR de 3,2 y 3,3 respectivamente. Dentro de las causas evidenciadas en las entrevistas, las dolencias obedecen a: las condiciones de trabajo, cambio de modalidad, aprendizaje de entornos virtuales, precariedad laboral y temor de ser despedidos. Se concluye que la ocurrencia de la pandemia Covid19 incremento el grado de exposición de factores de riesgo vinculados con las características de la tarea docente que ha afectado la salud mental y emocional.

Published: February 2022

El impacto ambiental y económico que genera el uso indiscriminado de productos químicos, para controlar plagas y enfermedades de los cultivos, ha generado preocupación a los agricultores en general, debido al alto costo y a los daños causados. Con base en esta situación y con el fin de controlar algunas plagas y enfermedades de los cultivos de alto interés en nuestro país, se realizó una investigación para desarrollar un bioproducto de utilidad que mejore las condiciones de cultivos afectados por esta problemática. El componente principal del producto es el mucílago de cacao (Theobroma cacao L.) que a pesar de ser un desecho puede ser aprovechado para elaborar mezclas fermentadas con ácidos débiles (ácido cítrico y ácido acético), que resultan eficientes para combatir algunos fitopatógenos. Se pudo comprobar que algunos cultivos de cacao de dos cantones pertenecientes a la provincia del Guayas se beneficiaron con la aplicación del producto (al 80% v/v), pues este resultó útil para alejar insectos y mejorar su aspecto de forma general, probablemente porque tenga acción antimicótica frente al hongo Moniliophthora roreri, el cual es común en este tipo de plantaciones; teniendo en cuenta que esta enfermedad ataca a los cultivos de cacao de todo el país y genera innumerables pérdidas para los agricultores; esta propuesta representa una alternativa ecológica para reducir los gastos e impactos ambientales, utilizando un bioantimicrobiano de bajo costo de producción y eficaz para controlar las plagas y enfermedades, sin daños visibles en las plantaciones tratadas.

Diseases affecting Mushrooms in Africa was reviewed in this study. Mushrooms are fleshy saprophytic fungi with noticeable fruiting bodies, achlorophylous and large enough to be harvested by hand. Edible mushrooms are highly nutritious and can be used as alternatives to meat, milk and eggs. Mushrooms have a history of economic importance in Africa as food and as medicine serving as good health supplements for the treatment of certain diseases of mankind. Mushrooms like other cultivated vegetable crops are subject to attack by pests and pathogens. Mushrooms in Africa are susceptible to a variety of viral, bacterial and fungal diseases that may affect mushroom yield and quality. Intensive cultivation of edible mushroom is often affected by some fungal and bacterial diseases that frequently cause dramatic losses. Pests and disease problems have higher chances of occurring when mushrooms are grown in one location over a long period of time. These infections are also facilitated by the prevalent conditions such as warm temperature, humidity, carbon dioxide levels and presence of pests under which the mushroom cultivation is carried out. There are other major causes of mushroom diseases besides fungi, bacteria, nematodes, viruses or pests. These are abiotic stress namely nutrient deficiencies, toxic chemicals, improper climatic conditions as well as poor ventilation which cause mushroom abnormalities. Some mushroom diseases are very difficult to control. However, careful farm management and extreme hygiene may prevent major attacks. Moreover, shelf life quality is severely affected by diseases that are still asymptomatic at the time of harvest. Strict maintenance of sanitation and hygiene in the farm helps to control mushroom diseases. Some control measures include the use of disinfectants such as chlorine and the application of selected fungicides. However, this involves significant costs and leaves undesired residues in the ecosystem. Most chemicals that are still allowed have failed to adequately control major mushroom diseases as resistance is easily induced. Other control measures such as bio-control and the use of resistant varieties are suggested good alternatives to chemical control. More research is required to detect the best pesticide-free alternatives for controlling the diseases and pests of mushrooms for the preservation of Africa’s precious heritage, mushrooms.

Yellow catfish (Pelteobagrus fulvidraco) are freshwater species native to Chinese waters. The aim of the study is to provide a better understanding on the present trends in the economic and technical efficiency of Yellow catfish (Pelteobagrus fulvidraco) production in China and learn from the Chinese wider experiences as a guide to the developing countries as they strive to develop their aquaculture sectors. The method of the study employed secondary data information collected from the reputable sources such as Food and Agriculture Organization of the United Nations, Nanjing Agriculture University-electronic library, China fisheries year books and annual reports including other relevant websites browsed containing some valuable information about Chinese aquaculture status and the data gathered was analyzed. Freshwater aquaculture in China has made a concerted effort to uplift culture practices on selected, high-valued, indigenous fish species. Currently yellow catfish has well established seed production technology, feed production, and efficient culture technology systems. It’s economically preferred by many consumers both in the local markets as well as international markets particularly by the south-eastern Asian countries like Japan and Korea. Despite the economic importance of yellow catfish species in the aquaculture sector, there is still limited information on its economic and technical efficiency production. Thus, this review paper highlights the economic and technical efficiency of yellow catfish production performances and focus on identifying critical matters that can support and improve yellow catfish productions in China as well as in the developing countries.

A 56 year old gentleman with no known comorbidities presented with pain abdomen for 1 month. Triphasic CECT abdomen showed features of cirrhosis with surface irregularities, fissural widening and volume redistribution changes in the liver. Segment VII of liver showed an arterial enhancing lesion measuring 4.2 x 3.5cm showing washout in delayed phase. In view of BCLC A stage with Child Pugh B7, ablation was planned. Before proceeding with ablation, in view of very high alpha-fetoprotein (AFP) level of 9836 ng/mL, he was advised for metastatic evaluation with 18F-FDG PET-CT. The PET scan showed abnormal heterogeneous increased FDG uptake in segment VII of liver (SUV Max 4.7) with arterial enhancement and washout suggestive of metabolically active hepatocellular carcinoma. Also seen was an abnormal linear increased FDG uptake in right branch of portal vein (SUV Max 4.8) which was suggestive of portal vein invasion. In view of portal vein tumor thrombus, ablation procedure was deferred for the patient. Role of PET scan in HCC with vascular invasion is not yet defined. Poor specificity of FDG PET is the major hindrance in establishing PET scan as diagnostic tool for vascular invasion. In small segment invasion when CECT is not able to differentiate between tumour versus bland thrombus PET scan may be significant tool to differentiate between bland thrombus and tumour thrombus. Vascular invasion confirmation have treatment related and prognostic significance. There is a need for a prospective study evaluating the prognostic significance of PET scan based diagnosis of vascular invasion.

Létezik-e német hegemónia az Európai Parlamentben?
Authors: Baranyi Márton
Published: February 2022

Az Európai Unión belüli német hegemónia vizsgálata és értékelése egy örökzöld, ám egyúttal vitatott kutatási témának számít. Egyrészről nem tisztázott, hogy mely kritériumok teljesülése esetén számít egy domináns hatalom hegemónnak, másrészről Németországnak az Európában betöltött szerepe kapcsán sem világos, hogy a múltjából fakadó adósságából eredően milyen mértékben hajlandó az európai vezető szerepnek eleget tenni. A jelen tanulmányban a német hegemóniával kapcsolatos vizsgálat középpontjában az Európai Parlament áll, de meg kell jegyezni, hogy az intézmény nem tekinthető az EU-n belüli német hegemónia elsődleges megnyilvánulási terepének. Az elemzés a 2014–2019-es parlamenti ciklusra fókuszál, s az EP-képviselők törvénykezési aktivitásán keresztül világítja meg a német hegemónia mértékét, és különböző mutatók értékelésével arra a következtetésre jut, hogy bár az adott időszakban a vezető pozíciók tekintetében túlsúlyban voltak a német képviselők, a parlamenti aktivitás már korántsem német dominanciát tükröz.
A nép nélküli néppártok : A német néppártok politikai státuszának változása 1990-2021 között
Authors: Molnár Tamás Levente , Tóth Beáta
Published: February 2022

Németországban az 1949 óta eltelt időszak két meghatározó néppártja, a CDU/CSU és az SPD a német újraegyesítés óta eltelt több mint 30 évben fokozatosan veszített a politikai befolyásából. E jelenség mögött számos tényező áll: szociológiai szempontból a társadalom fokozódó individualizálódása, mely a társadalmilag önszerveződő csoportokban való egyre passzívabb részvételben ölt testet; a politikai folyamatok professzionalizálódása, ami a politikai elitek és a társadalom közötti elidegenedéshez vezet; valamint a német társadalom diverzebbé válása, ami az állampolgároknak a politika iránti jelentősen eltérő elvárásainak artikulálásában fejeződik ki. Politikai szempontból a néppártok szerepének csökkenése mögött álló leglényegesebb tényezőt azok a döntések jelentik, amelyeket a néppártok a kormányzásuk idején hoztak, de jelentősen kikezdték az adott párt identitásmagjának egy bizonyos részét. Ennek hatására a néppártok már nem tudták lefedni a teljes politikai spektrumot, s ennek következményeként új pártok jelentek meg. A német politika az utóbbi bő három évtizedben jelentős mértékben „hollandizálódott”; korábban nem látott koalíciós formák léteznek az országban, a CDU/CSU és az SPD politikai súlya erodálódott, ugyanakkor a mai napig meghatározó részét képezik a német pártrendszernek.
Magyar vállalatok külföldi tőkeberuházásai: helyzetkép a járvány tükrében
Authors: Endrődi-Kovács Viktória , Goreczky Péter
Published: February 2022

A Covid19-járvány világszerte jelentős mértékben csökkentette a külföldre irányuló beruházási kedvet. Ennek ellenére a magyar külgazdasági törekvések között továbbra is nagy hangsúlyt kap a hazai vállalatok tőkekihelyezéseinek a támogatása. A jelen tanulmány célja annak a kiderítése, hogy a pandémia hogyan hatott Magyarország tőkekihelyező vállalataira, miként befolyásolta a külföldi beruházási stratégiájukat, illetve a válság nyomán változott-e az állami támogatások iránti igény. A tanulmány elkészítése során a módszertani eszközök közül a szekunder adatok elemzésével, illetve a tőkekihelyező magyar vállalatokkal készített interjúkon alapuló esettanulmányokkal éltünk. A fő konklúziónk, hogy a járvány nem befolyásolta érdemben sem a már előkészítési fázisban lévő projekteket, sem a jövőbeni beruházások irányát, vagyis összességében a válság nem csökkentette a vizsgálatba bevont cégek külföldi beruházási hajlandóságát. A tanulmány fő értéke az elvégzett primer kutatás, illetve a választott téma, amelyről eddig csak kevés hazai elemzés született.

THE PROCESS OF SETTLING MUSLIMS IN CHINA DURING THE MING DYNASTY
Authors: Ernazarov Odiljon
Published: February 2022

The article presents information about sociopolitical, economic, and cultural conditions of China in the XIV-XVI centuries, the spread of Islam in China and its adaptation to the local environment, the participation of Muslim nations in the social, economic, cultural life, and educational process of the country. During this period, the status of Muslims as a “community migrating from Central Asia” changed to the name of an “ethnic minority” firmly established in China. In the reign of the Ming Dynasty, the Hui Muslim population in Shanghai and Gansu increased even more. The Ming emperors granted Muslims certain religious, political, economic, and social freedoms. Most Muslims served in the Ming army and held senior military and civilian positions. The reign of Ming Taizu, one of the Ming emperors, was a period of social change for the Muslim community from outsiders to insiders. We can describe this period as a period in which Muslims are relatively adapting to Chinese cultural norms or experiencing a process of sinicization. In this regard, Muslim communities that lived peaceful and prosperous life during the Ming Dynasty underwent cultural changes. During the Ming period, regional differences were observed in the integration of Muslims into society. For example, Muslims living in the northern and southwestern regions of China were fully adapted to local conditions. Muslims in the Northwest, on the other hand, had maintained ethnic and religious identity, worldviews, and lifestyles.
