A Case of Blue Nevus Mimicking Malignant Melanoma Within a Keloid Scar
Authors: Bostan Ecem , Yalici-Armagan Basak , Gokoz Ozay , Karaduman Aysen
Published: June 2021

Blue nevus is a type of melanocytic nevus which clinically presents itself as blue/gray plaque or nodule. It most commonly develops upon distal extremities especially dorsal hands and feet, trunk and scalp. Histopathologically, heavy melanocyte aggregations in the deep dermis result in blue nevus formation. Different types of blue nevus include common blue nevus, cellular blue nevus, plaque-type blue nevus, combined blue nevus, desmoplastic blue nevus and subungal blue nevus. Although clinical findings may be sufficient to diagnose blue nevus, dermoscopy could be used as a helpful tool to aid in reaching the correct diagnosis. Dermoscopy usually shows diffuse blue-gray structureless area but since atypical clinical and dermoscopical features may be observed, histopathological diagnosis is the definitive step to differentiate blue nevus from its mimickers such as malignant melanoma. We want to present an interesting case of blue nevus mimicking malignant melanoma developing in a scar.

Sugárérzékenységi vizsgálatok: a kolónia-képző assay és a comet-assay próbája
Authors: Kis Enikő
Published: June 2021

Az orvosi gyakorlatban közismert tény, hogy a sugárterápiára adott biológiai válasz egyénenként eltérő. Számos kutató és szerző foglalkozik az egyéni sugárérzékenység fogalmával, lehetséges gyakorlati következményeivel és kimutatásával. Célszerű lenne hasonló eljárást bevezetni a sugárbalesetek helyszínén, vagy egyéb sugárveszélyes területen bevetésre kerülő katasztrófavédelmi dolgozók és katonákkörében is. Jelen tanulmányunkban egyik lehetséges, bár a nemzetközi irodalomban még meglehetősen vitatott szűrési módszer alkalmazhatóságát tárgyaljuk.A szerző ezúton szeretne köszönetet mondani dr. Sáfrány Gézának, MD, PhD, DSc a munkaelvégzéséhez és a cikk megírásában nyújtott segítségéért.
Fertőtlenítőszer mennyiségi vizsgálata vízminőségi modellezéssel
Authors: Salamon Endre
Published: June 2021

A ivóvíz kezelése során és az elosztó hálózaton alkalmazott fertőtlenítő szer mennyisége a vízbiztonság szempontjából az egyik legkritikusabb paraméter. Ennek oka nem csak megfelelő csírátlanítás és a gazdaságos üzem igénye, hanem a képződő melléktermékek mennyiségének elfogadható szinten tartása is.Ebben a tanulmányban a vízminőségi modell eredményeinek kinetikai paraméterekre való érzékenysége kerül bemutatásra. A modellfuttatások alapján jól igazolható, hogy a klór átalakulási sebessége a befolyásoló tényezők ellenére jól nyomon követhető és leírható, azonban a modellek hitelesítése komoly nehézségekbe is ütközhet. Ennek ellenére a számítógépes vízminőségi számításokkal a költségek és a kockázatok számszerűen vizsgálhatóak és minimalizálhatóak.

Authors: Krajnc Zoltán
Published: June 2021

A pilótanélküli légijárművek katonai alkalmazása már több évtizedes múltra tekint vissza, a Szövetségben a felhasználásuk jelentősége a 90-es években növekedett meg igazán. A tanulmány összegzi a pilótanélküli légijárművek alkalmazásnak doktrinális hátterét, stratégiai koncepcióját. A pilóta nélküli légijármű rendszerek, ugyanolyan platformnak, tekinthetőek, mint a pilóta által vezetett fegyverrendszerek a műveleti alkalmazási formákat illetően. Az UAS-ok gyakorlatilag, mint az adott szerepkörre létrehozott komplex légi támadó kötelékek alkotó elemeiként a képességeiknek megfelelő feladattal integrálódhatnak. A pilóta nélküli légijármű rendszerek széleskörűen alkalmazhatóak a védelmi-, és támadó légi szembenállás, légi csapásmérés eszközeként, valamint felderítőmegfigyelő feladatkörökben egyaránt.

Authors: Czakó Levente , Karches Tamás
Published: June 2021

A különböző szennyvízkibocsátások elvezetése, kezelése kiemelt fontosságú a közegészségügyi kockázatok elkerülése és a befogadó vízminőségének megóvása érdekében. A csatornahálózat kiépítésekor arra törekszünk, hogy a szennyvíz szállítását úgy végezzük, hogy abban biológiai folyamatok, iszaplerakódás ne induljon be. Az urbanizáció hatására a meglévő hálózatok túlterheltté válhatnak, a telepre a szennyvíz hosszabb úton érkezhet meg. A kiszolgált agglomeráció bővülése esetén szóba jöhetnek decentralizált szennyvízkezelő megoldások, melyek lehetnek a szennyvíz keletkezési helyénél létesített több kisebb kapacitású telep, kisebb lakóövezet, egy-két családot kiszolgáló egyedi kisberendezés és/vagy természetközeli (extenzív) szennyvíztisztítási rendszerek. A cikk célja ezen lehetőségek feltárása. A projekt az Európai Unió támogatásával, az Európai Szociális Alap (ESZA) társfinanszírozásával valósul meg (a támogatási szerződés száma: EFOP-3.6.1-16-2016-00025, projekt címe: A vízgazdálkodási felsőoktatás erősítése az intelligens szakosodás keretében).

Authors: Hábermayer Tamás , Túriné Barta Ágnes , Muhoray Árpád
Published: June 2021

A katasztrófavédelmi önkéntesek különböző módon, generációnként eltérő gyakorisággal és funkcióval használják a közösségi média nyújtotta lehetőségeket. Az elektronikus eszközök technológiai fejlődése, illetve a szolgáltatók által biztosított lehetőségek az internet elérését és ezen alkalmazások használatát egyre könnyebbé teszik. A fiatalabb generációk ezzel napi szinten együtt élnek, míg az idősebb generációk tagjai közül kevesebben képesek alkalmazkodni ezekhez. A közösségi média használata ugyanakkor számos lehetőséget biztosít – például szöveges és képi információk valós idejű megosztása, az önkéntes csoport szervezése vagy riasztás – de számos veszélyt is rejt magában. A szerzők az ár- és belvíz elleni védekezések jövőbeli szervezése érdekében vizsgálják a katasztrófavédelmi önkéntesek közösségi média használatát, és tesznek javaslatot a hatékony alkalmazáshoz.
A XIII. Honvédelmi Minisztérium fejezet személyi juttatásainak és reálkereseteinek alakulása a 2005-2017. közötti időszakban
Authors: Kenessei Zsolt , Pap Andrea
Published: June 2021

Az elmúlt néhány évben a XIII. Honvédelmi Minisztérium fejezetnél az állomány személyi juttatásai nagymértékben megnövekedtek. Köszönhető ez annak, hogy kormánydöntés alapján a katonák illetménye 2015 júliusában egy egyszeri átlagos 30 %-os, majd ezt követően 2019. január 01-jével bezárólag évente átlagosan bruttó 5 %-os mértékben emelkedett, a közalkalmazottak részére pedig a honvédelmi ágazati pótlék került bevezetésre. Ezekre azért volt szükség, mert egyrészt az utolsó jelentősebb bérfejlesztés 2005-2006-ban történt, másrészt a nemzetgazdaságban folyamatosan emelésre került a minimálbér és a garantált bérminimum, melynek következtében a fejezetnél dolgozók bére jóval elmaradt a civil munkaerőpiacon hasonló végzettséggel rendelkező szakemberek jövedelmétől. Cikkünkben azt vizsgáljuk meg, hogy hogyan alakultak a személyi juttatások és az átlagkeresetek 2005-től 2017-ig nominál- és reálértékben, ha bázisnak a 2005-ös évet tekintjük.

Authors: Alhosban Ahmad
Published: June 2021

Global Satellite Navigation Systems (GNSS) applications -using different satellite signals in space- are currently and hugely subjected to Electronic Attacks (EAs) such as Jamming, Spoofing, and/or Meaconing. Many accidents were observed in the past decade, while huge dependency on GNSS applications in governmental and private critical infrastructure, in both civil and military aspects. The EAs could be expensive and high-power such as the military-grade jammers, which are an integral pillar of navigation warfare (NAVWAR) strategies. On the other hand, EAs could be cheap and low-power such as the so-called Personal Protection Devices (PPD), which they are widely available. Electronic Attacks, most critically observed by ICAO and FAA, are in Ground Based Augmentation System -(GNSS/GBAS) Landing systems, in which is riskier and more critical than other applications due to the sensitivity of the final landing phase of all flights. The objective of this study is to evaluate the impact of the three different types of EA on the performance GNSS/GBAS landing system. On the other hand, to address and examine their latest proposed Electronic Protection Measures (EPM).

Authors:   , Aka Sharon
Published: June 2021

Problem Research was needed to determine the relationship between pastoral CE and employee engagement to guide policy implementation as well as future efforts for pastoral professional development within the Adventist organization. Method This study presents a new theoretical Adventist pastor development model integrating several theories and concepts including: the call, the Seven Core Qualities of an NAD pastor framework, andragogy, CE, SDT, and employee engagement. Employee engagement was measured using Herzberg's hygiene-motivation factor employee engagement theory. Comparisons were conducted on six groups of pastors related to selfreported participation in annual CE. Results Major research findings indicate that pastors, perhaps inevitably as humans, are complex, and several factors seem to work synergistically to result in positive hygiene and motivation (employee engagement) scores including: The call, age, having adult children, ethnicity, a combination of CE and age, and a combination of children and CE. Of key importance, increased knowledge and specific life experiences work together to create a more engaged pastor. CE as a stand-alone factor did not have a statistically significant positive impact on hygiene or motivation employee engagement scores based on this data. Factors that have a negative impact on hygiene and motivation scores are family suffering, feeling like leaving ministry, doubting God’s call, ethnicity, and children at home or no children at all, and. The most popular CE activity of Adventist pastors was conventions, the least favorite was creating CE content for peers. Conclusions Recommendations for pastoral professional practice are related to five areas of focus: education, CE policy, coaching and mentoring, work environments, and pastoral family supports. Recommendations for future research are specific to four areas: pastoral CE, pastoral development factors, work environments, and family support. More scholarly research on pastors is urgently needed utilizing a factorial approach.

Poucos estudos investigam como o empreendedorismo afeta a subjetividade dos que empreendem, especialmente das mulheres no meio rural, tradicionalmente ligado ao universo masculino. O objetivo deste artigo é verificar como se constitui a subjetividade da mulher empreendedora do meio rural. Com abordagem qualitativa, a técnica de coleta de dados foi a entrevista semiestruturada e a análise dos dados se deu por meio dos núcleos de significação. Os resultados apontaram que a experiência empreendedora resulta em uma configuração particular de empreendimento-família, tempo e autopercepção com sentido totalmente peculiar a cada sujeito, sua história de vida e meio em que empreende.

Metodología “SUCCES”
Authors: Morales Viesca Francisco de Paula
Published: June 2021

Dentro de las actividades docentes, la proyección de presentaciones suele enfrentar el problema de la organización del material que se impartirá para mantener la atención de los alumnos. Para solventar la complejidad anterior, se presenta como una metodología memorable, en el sentido de facilidad de evocación de la memoria, el método “SUCCES”, propuesto en el año 2007 por los hermanos Heath en su libro Made to Stick; el nombre por sus siglas en inglés: s (simple), u (unexpected), c (concrete), c (credible), e (emotion), s (storytelling).

Diseño y validación de un programa de formación de tutores
Authors: Macías Esparza Ana Cecilia , Ibarra Mesa Sergio
Published: June 2021

Se presenta la experiencia educativa resultante del diseño y la validación de un programa de formación de tutores para el Centro Regional de Educación Normal del Estado de Aguascalientes (CRENA), con el fin de atender la necesidad derivada del establecimiento de la tutoría como elemento curricular en la formación de estudiantes de escuelas normales (SEP, 2012); si bien, la institución tenía un Programa Institucional de Tutorías (PIT), éste debía ser adaptado tanto a lo solicitado por la SEP como a las propias necesidades de los agentes educativos de la misma. De las concepciones emitidas por instituciones y autores sobre la tutoría, se parte como una base teórica que permite explicar las acciones realizadas para llevar a cabo el proyecto educativo que se presenta, y se continúa con los resultados obtenidos, en los que sobresalen los aprendizajes adquiridos, así como su transferencia por parte de los tutores formados; todo ello, encaminado a la mejora de futuras experiencias de esta naturaleza.
La biblioteca pública como área de oportunidad para los estudiantes de bachillerato
Authors: Venegas Medrano Marco Antonio
Published: June 2021

Se expone la idea de un “foro abierto” como una de las maneras en que se puede vincular el trabajo cotidiano que se realiza en el aula con las bibliotecas públicas de nuestro país, que ahora se conciben como centros culturales. De esta manera, ciertas actividades académicas pueden llevarse a cabo en estos espacios abiertos a todo público, para que, con ello, exista una relación directa entre el trabajo interno del aula y la ciudadanía en general. El foro abierto al público es una actividad, de entre varias, que se pueden ofrecer a la ciudadanía. Entre otras están las mesas de debate, exposiciones temáticas, conferencias y mesas redondas.

8 neuro-principios para el aprendizaje
Authors: Pirela Sánchez Gabriela
Published: June 2021

Si el órgano en donde ocurre el aprendizaje es el cerebro, entonces deberíamos conocerlo mejor. ¿Los docentes saben lo suficiente del cerebro para enseñar?, si lo supieran ¿impactaría en sus clases? Estas preguntas pueden ser respondidas desde muchos ángulos, el que se abordará es el de las neurociencias por su relevante vinculación con el aprendizaje. Se pretende sensibilizar a los docentes de la necesidad de conocer los hallazgos de las neurociencias que impactan en la enseñanza y el aprendizaje. Se compartirán ocho principios sólidos que tienen la intención de dejar abierta la imaginación del lector, para que éste reinvente y dialogue creativamente con su didáctica. Se concluye proponiendo la práctica de algunos principios más respetuosos de cómo aprenden mejor los seres humanos.

Authors: Ferrer Guerra Julián , Moncada Sierra Carlos Alberto , Guerrero Barrón Alejandro
Published: June 2021

La pandemia ocasionada por el coronavirus y su enfermedad el COVID-19 ha impactado en una gran cantidad de actividades humanas a nivel global, la educación se vio particularmente impactada al decretarse la separación social y, por consiguiente, el cierre temporal de escuelas. Estudiantes y docentes pasaron de una modalidad educativa basada preponderantemente en lo presencial, a una modalidad de distribución basada en Internet, sin que necesariamente estuviesen preparados para ello. Este artículo evalúa el impacto en la percepción de los estudiantes que han enfrentado el distanciamiento social obligatorio, modificando su modalidad educativa cara a cara tradicional, a una modalidad no presencial en línea o virtual, así como evaluar cuál ha sido su cambio de perspectiva entre ambas modalidades. Los resultados demuestran que hubo una disminución en la percepción general que observaron los estudiantes como resultado del cambio de una modalidad presencial respecto a la virtual o en línea, lo cual podría ser considerado como un nivel de insatisfacción.
Performance of Self-compacting Concrete with Stainless Steel Slag Versus Fly Ash as Fillers: A Comparative Study
Authors: Sheen Yeong-Nain , Le Duc-Hien , Lam My Ngoc-Tra
Published: June 2021

Recently, stainless steel slag -a byproduct of manufacturing stainless steel is accepted as a cementitious material, the chemical characteristics of which are highly variant. This study reuses two types of stainless steel reducing slag with specific surface area of 1766 cm2/g (S1) and 7970 cm2/g (S2) in developing self-compacting concrete (SCC). Particularly, two S2-blended SCCs incorporating with S1 and fly ash as fillers (calling as S-mix and F-mix) were prepared for a comparative investigation. In both SCCs, ordinary Portland cement was replaced by S2 with various ratios (from 0 % to 50 %, increment 10 %). Testing results show that in fresh state, the F-mix exhibits higher workability and longer initial setting time than those of S-mix. In hardened state, 10 % compressive strength loss was realized as increasing S2 content up to 30 % in the both SCCs; the strength of F-mix is up to 1.9 times of S-mix at the same rate of S2 replacement. Water absorption of the F-mix was below 3 %, suggested as a “good” quality concrete; whilst the S-mix could be longs to an “average” one. Resistivity and sulfate resistance of F-mix are considerably higher than those of S-mix. Moreover, based on the obtained data, compressive strength and electrical resistivity are correlated well with a logarithmic form.

Tatton-Brown-Rahman syndrome (TBRS) is an overgrowth disorder caused by germline heterozygous mutations in the DNA methyltransferase DNMT3A. DNMT3A is a critical regulator of hematopoietic stem cell (HSC) differentiation and somatic DNMT3A mutations are frequent in hematologic malignancies and clonal hematopoiesis. Yet, the impact of constitutive DNMT3A mutation on hematopoiesis in TBRS is undefined. In order to establish how constitutive mutation of DNMT3A impacts blood development in TBRS we gathered clinical data and analyzed blood parameters in 18 individuals with TBRS. We also determined the distribution of major peripheral blood cell lineages by flow cytometric analyses. Our analyses revealed non-anemic macrocytosis, a relative decrease in lymphocytes and increase in neutrophils in TBRS individuals compared to unaffected controls. We were able to recapitulate these hematologic phenotypes in multiple murine models of TBRS and identified rare hematological and non-hematological malignancies associated with constitutive Dnmt3a mutation. We further show that loss of DNMT3A in TBRS is associated with an altered DNA methylation landscape in hematopoietic cells affecting regions critical to stem cell function and tumorigenesis. Overall, our data identify key hematopoietic effects driven by DNMT3A mutation with clinical implications for individuals with TBRS and DNMT3A-associated clonal hematopoiesis or malignancies.

Published: June 2021

AKR1D1 has been recently recognized as novel candidate gene regulating CYP450 coexpression. The AKR1D1 3’-UTR SNP (rs1872930) functional genetic variation was considered as important source of phenotypic variation in the activity of CYP450. The minor allele frequency of rs1872930 varies among populations suggesting population specific pharmacogenetic implications. The aim of the present study was to determine the AKR1D1 (rs1872930) minor allele frequencies and genotypes distribution in a population from Republic of Macedonia. Four hundred and fifty unrelated Macedonian subjects were studied. AKR1D1 variant allele was detected by real time polymerase chain reaction. The distribution of AKR1D1*1/*1, *1/*36 and *36/*36 genotypes was 0.569, 0.360 and 0.071, respectively. The overall frequency of AKR1D1*36 variant allele was 0.251. Our study is the first to assess the frequency distribution of the AKR1D1*36 (rs1872930) genetic variant in population from Republic of Macedonia and the findings are in accordance with the frequency reported for the Caucasian population.

Introduction: Gingival recession is established through several factors and its treatment can be planned integrating surgical procedures with the aid of orthodontic treatment. Methods: In this context, a 36-year-old woman sought dental treatment to realign the right lower central incisor. A localized gingival recession was verified, being related to poor positioning of the root. The patient had undergone previous orthodontic treatment, as well as periodontal surgical treatment, after which there was no success. Results: After the planning of the case, the dental element was reallocated through orthodontic movement and then the periodontal surgical treatment was performed. With the results obtained, the improvement of gingival recession through orthodontic and periodontal surgical treatment is discussed. Conclusions: This clinical report shows that the gingival graft, performed after tooth movement, can increase the probability of good results in reducing root exposure.

Published: June 2021

Objetivo: Discorrer a cerca de um caso de rara ocorrência de neoplasia endócrina múltipla tipo 1 e discutir aspectos relacionados à importância do diagnóstico precoce. Métodos: Informações obtidas por vias de revisão do prontuário, entrevista com o paciente, registro fotográfico dos exames aos quais o paciente foi submetido. Relato de caso: Mulher, 60 anos, história pregressa de amenorreia secundária desde os 18 anos.  À época, procurou ginecologista, no qual foi verificado hiperprolactinemia e prescrito bromocriptina. Ficou sem acompanhamento endocrinológico por aproximadamente quarenta anos, quando foi encaminhada para consulta especializada. Em consulta, observado hiperprolactinemia, hipercalcemia e PTH elevado. Além de exames de imagem com microadenoma hipofisário, nódulos na tireoide, pancreáticos e adrenais. Já com o diagnóstico clínico de NEM1, atualmente a paciente e alguns familiares estão sendo convocados para coleta de material genético para análise e provável detecção de perfil de mutação. Considerações finais: Foi possível concluir que o NEM-1 se não diagnosticado no início pode causar síndromes hormonais importantes, assim como é importante considerá-la dentre os diagnósticos diferenciais.
