La transposición de la Directiva de Procedimientos de Asilo y la efectividad coercitiva de las decisiones de infracción de la Comisión Europea
Authors: Fernández Burgueño Borja
Published: April 2018

En este trabajo se estudia el nivel de transposición de la Directiva de Procedimientos de Asilo, centrándose en el papel de la Comisión Europea como órgano supervisor de la implantación del Derecho de la Unión Europea (UE) en los Estados Miembros. En concreto, se analizará el estado de tramitación de los procedimientos de infracción a los Estados miembros incoados por la Comisión Europea por incumplir con sus obligaciones de transposición, llegando a las siguientes conclusiones: (i) los progresos en los procedimientos de infracción han sido mínimos y muchos de ellos han quedado congelados en fases intermedias; (ii) la inactividad de la Comisión Europea equivale de facto a un consentimiento implícito para que los Estados infractores continúen con sus prácticas contrarias al derecho de la UE; y (iii) resulta necesario un papel más activo de la Comisión Europea. This paper studies the record on transposition of the Asylum Procedures Directive, focusing on the role of the European Commission as the monitoring body of the implementation of the European Union (EU) Law among Member States. In particular, it will be analysed the current status of the infringement proceedings brought by the Commission to State Members for failing to comply with their transposition obligations, finding that: (i) the progress made in the infringement proceedings has been marginal and many proceedings have been put on ice at intermediate stages; (ii) the Commission’s inactivity amount to an implied consent for the infringing Member States to continue with their practices contrary to Community law; and (iii) a more active role of the European Commission is needed.

Orality versus Written Legislation: Oral History as used in Zimbabwe`s Post-2000 Land Reform Programme
Authors: Muchefa Livingstone , Phiri Calvin
Published: April 2018

Zimbabwe became a colony of the British Empire on 13 September 1890, and attained independence in 1980. During the colonial period of 1890 to 1980 land was expropriated primarily from the indigenous Ndebele and the Shona tribal groups through the institutionalisation of legislation that brought about the segregation of Africans and paved the way for settlement and farming by whites. Between 1980 and 1990 there was little progress in terms of resettlement programmes because of financial constraints and the terms and conditions of the Lancaster House Agreement regarding the willing seller willing buyer principle. There were serious economic challenges in the decade 1990 to 2000, but the period post 2000 witnessed brisk land repossessions which were spearheaded by war veterans and politicians. At the heart of the â€œland invasions,â€ as they were popularly termed, lay historical injustices. This paper seeks to provide an insight into the centrality of the oral tradition or oral history as legal basis for the land repossessions that took place. Neither legal recourse nor visiting archives and other information centres for the purposes of authentication were a priority. The Lancaster Constitution was viewed as an obstacle when dealing with land. The National Archives of Zimbabwe is placed in context within the situation discussed.

Послеоперационный перитонит и аррозионное кровотечение после резекции поджелудочной железы являются самыми грозными осложнениями и сопровождаются высокой летальностью. Экстирпация культи поджелудочной железы, на наш взгляд, является оптимальным методом лечения инфекционных и геморрагических осложнений
Сравнительный анализ пункционной аспирационной и биопсии троакаром для диагностики абдоминальных объёмных образований
Authors: Азаб Хуссейн Ахмад , Торба А. В.
Published: April 2018

Сравнили показатели чувствительности и специфичности  чрезкожной аспирационной биопсии тонкой иглой  (ТАБ) и биопсии троакаром (БТ) для окончательной диагностики предполагаемых новообразований органов брюшной полости у 140 больных. Диагностическая точность обоих методов для подтверждения окончательного диагноза сопоставлена. ТАБ и БТ сопровождались истинно-положительными результатами у 111 из 129 (86%) больных. При этом правильный окончательный диагноз злокачественного новообразования был у 104 из 129 обследованных (80,6%). В целом у всей группы больных чувствительность методов составила 90,7%. Как ТАБ, так и БТ имели 100%-ную специфичность, хотя в одном случае феохромоцитома была неправильно идентифицирована с помощью БТ как недифференцированный рак.  Кроме этого, расхождения ТАБ и БТ были у 2 больных по результатам ТАБ и у 4 – по данным БТ. У 12 больных, окончательным диагнозом которых были доброкачественные опухоли, показатели диагностической точности таковы: ТАБ – 11 правильных ответов, БТ – 9. Адекватная подготовка препаратов  для цитологического исследования при ТАБ обеспечивала окончательный ответ в течение 1 часа в 103 и 141 (73%) пункций, избавляя многих больных от повторных ТАБ. Осложнений ТАБ и БТ не выявлено. Таким образом, ТАБ обладает большей чувствительностью, чем БТ для диагностики новообразований брюшной полости. Кроме этого, ТАБ имеет высшие показатели диагностической специфичности и точности, чем БТ и особенно при доброкачественных процессах. Обе методики взаимно дополняют друг друга.

Published: April 2018

In many engineering applications, heat dissipation is an important factor which if not taken care of may lead to high thermal stresses and mechanical failures. The amount of heat dissipated depends on heat transfer coefficient and surface area which can be enhanced by use of extended surfaces i.e. fins. Thermal Analysis of three fins namely Rectangular, Inclined Non-Uniform Perforated, Twin Extension was performed. The models were designed on Creo Parametric 4.0 and the analysis was carried out using ANSYS Workbench 15.0. The fins were analyzed for forced convection. The fins were compared on the basis of non-dimensional Nusselt number and Reynolds number which proved that Twin Extension fin was the most effective among all the three. It was followed by Inclined Non-Uniform Perforated fin.
Update on Hidradenitis Suppurativa (Part I): Epidemiology, Pathogenesis, Severity assessment and Comorbidities
Authors: Costa e Silva Miguel , Azevedo Filomena , Lisboa Carmen
Published: April 2018

Hidradenitis suppurativa (HS) is as a chronic, inflammatory and recurrent skin disease of the hair follicle. Prevalence of HS is a matter of debate, with estimate rates as low as 0.00033% and as high as 4.1%. HS prevalence appears significantly higher in women and has a mean age of onset in the early 20s. The primary histopathologic event seems to be a follicular hyperkeratosis with plugging, dilatation and rupture of the hair follicle resulting with subsequent inflammation and formation of abscesses and sinus tracts. The cause of this is likely multifactorial, involving genetic factors, cigarette smoking, mechanical stress, obesity, immune aberrant response and hormonal abnormalities. HS, as a chronic inflammatory dermatosis, is associated with a variety of concomitant and secondary diseases such as metabolic syndrome, inflammatory and rheumatologic diseases, depression and malignancy, and, for this reason HS management often requires a multidisciplinary team.
The spectrum of fibroelastolytic papulosis: a retrospective case series.
Authors: Cunha Nélia , Cabete Joana , João Alexandre , Lencastre André
Published: April 2018

Introduction: There is an overlap between clinical and pathological features of the entities known as pseudoxanthoma elasticum-like papillary dermal elastolysis (PXE-PDE) and white fibrous papulosis of the neck (WFPN). Although the term fibroelastolytic papulosis has been used to encompass both entities as spectrum variants of a one and only disease, many authors still differentiate the two.Methods: Cases of fibroelastolytic papulosis confirmed by histopathologic examination were retrospectively reviewed within a time frame of 2.5 years.Results: Five cases of fibroelastolytic papulosis were identified. All patients were females aged between 63 and 78 years, presenting with an asymptomatic eruption of isolated or coalescing white to yellow papules on the neck. Two of the patients also had involvement of other anatomical areas. In all cases histology demonstrated a significantly decreased or absent papillary dermal elastic plexus, a mild superficial perivascular lymphocytic infiltrate and sparse melanophages in the papillary dermis, without interface changes. A decrease in upper reticular dermal elastic fibers was noted in four cases and thickening of dermal collagen bundles in three cases. Dilated superficial dermal vessels were present in 3 cases and mild epidermal atrophy in one case.Conclusion: We find the differentiation of PXE-PDE and WFPN to be somewhat theoretical, often confusing, and based on non-significant subtle histological and clinical differences. In our opinion, we should not continue to use these terms, but favor the common term of fibroelastolytic papulosis.
Estudo retrospetivo de 109 doentes com escabiose: retrato de uma região
Authors: Kieselova Katarina , Santiago Felicidade , Henrique Martinha
Published: April 2018

Introdução: A escabiose é uma infestação cutânea frequente em todas as faixas etárias e representa um problema de saúde pública em certas comunidades. Em Portugal escasseiam os estudos sobre esta parasitose. O presente estudo teve como objetivo avaliar as principais características dos doentes diagnosticados com escabiose no Serviço de Dermatologia do Centro Hospitalar de Leiria.Material e Métodos: Realizámos um estudo observacional retrospetivo, incluindo os doentes com diagnóstico de escabiose observados na Consulta e urgência de Dermatologia geral e na Consulta e urgência de Dermatologia pediátrica do CHL, entre janeiro 2015 e dezembro 2016.Resultados: O estudo incluiu 109 doentes (69 crianças; 40 adultos) com uma idade média de 6,95 anos (± 5,92) no grupo pediátrico e 47,33 anos (± 22,06) no grupo dos adultos. Em 2015 foram diagnosticados 46 casos de escabiose e, em 2016, 63 casos, o que representou um incremento de 37%. Na maioria dos doentes (74,3%) não foi possível apurar uma fonte de contágio. O atraso no diagnóstico de escabiose foi semelhante em ambos os grupos (50 dias no grupo pediátrico versus 58 dias no grupo dos adultos), embora a concordância de diagnóstico tenha sido mais elevada no grupo pediátrico (70,8% vs 27,6%, p = 0,000).Conclusão: Apresentamos o primeiro estudo de escabiose com o diagnóstico estabelecido pela Dermatologia em Portugal, apontando para a elevada incidência, provavelmente, ainda subestimada. À semelhança de outras séries internacionais, o atraso no diagnóstico continua a ser relevante, tanto em adultos como em crianças, mas realça-se que o grau de concordância de diagnóstico é superior quando se trata da idade pediátrica. O melhor conhecimento da realidade epidemiológica da escabiose permitiria delinear estratégias preventivas e de apoio social mais consistentes.

Authors: GUNASUNDERI R. , MAS HARIS M. R. H.
Published: April 2018

Chitosan entrapped ENR-50 (CTS-t-ENR) biocomposites developed were studiedfor the absorption and desorption of 2-naphthol in aqueous media. Biocomposites comprising chitosan (CTS) immobilized or trapped in a partially crosslinked ENR (designated as CTS-t-ENR) was prepared by homogenising CTS in ENR-50 latex with curative agents in the presence of acetic acid. It was found that absorption increased with the increase in the initial 2-naphthol concentrations. Chitosan powder was found to be a poor absorbent compared CTS-t-ENR biocomposites. Desorption studyrevealed that the 2-naphthol diffusedslowly in water. The biocomposites exhibited a good slow-release properties and this was proven by the kinetic studyusing zero order, firsorder, Higuchi equation and Kosmeyer Peppas equation. Thus, these biocomposites with a good controlled release and swelling properties could be very useful in agricultural application.

Published: April 2018

An efficienmethod for microcystin-LRin drinking water at the sub-ng/l level applying on-line solid phase extraction (SPE) with LC/MS/MS detection and comparing it to direct injection LC/MS/MS is presented. The performance of the method of direct injection did not signifiantly deviate from the SPE approach. However, the direct injection method used less sample volume (100 µl) in shorter analysis time (4 min) and allowed more sample throughput. Conversely, the uncertainty of measurement could be reduced using SPE.

Published: April 2018

In this study the contents of the 6th grade elementary school mathematics in U.S. military government period in Korea were analyzed as part of restoring the history of Korean elementary school mathematics education. The literature to be analyzed is ≪Elementary Sembon 6-1≫ and ≪Elementary Sembon 6-2≫. An analysis was made in terms of three aspects. In 2015 revised elementary mathematics curriculum, what contents in this two textbooks are not dealt with, what contents in this two textbooks are not dealt with explicitly but implicitly, and what contents in this two textbooks are dealt with? Especially, there are three kinds of contents which are not dealt with in 2015 revised elementary mathematics curriculum. Those are the contents which are shifted from elementary school mathematics to middle school mathematics, the contents which are dealt with in elementary school mathematics without shifting to middle school mathematics, and the contents which do not belong to school mathematics by their character. On the contents of the 6th grade elementary school mathematics in U.S. military government period in Korea, the findings based on results of the analysis can be obtained. First, the contents dealt with at that times were very different from the ones currently dealt with. Second, mathematics oriented contents and lifestyle oriented contents were mixed.

Authors:   The Korea Society Of Educational Studies In Mathematics, Lee Youn Mi , Lee Soo Jin
Published: April 2018

Past research on teachers' noticing have been mostly conducted to explore the level in which teachers could attend to the others' lessons, and the field is still short of studies investigating teachers' noticing of their own lessons. The present study attempted to understand prospective secondary mathematics teachers' noticing by analyzing the following two data: the evaluation of others' mathematics lesson and the reflection of their own mathematics lessons. The result of the present study suggests that the participating prospective secondary mathematics teachers paid close attention to teachers’ teaching activities and attempted to evaluate what they noticed. In addition, when the teachers evaluated the objects to which they had attended, a number of rationales were suggested including curriculum, students’ mathematical thinking, interests and participation. Finally, we discussed the implication of our study for prospective secondary mathematics teacher education.
An Analysis of the Elementary Mathematics Textbooks on the Generalization of Properties of Numbers and Operations
Authors:   The Korea Society Of Educational Studies In Mathematics, Pang JeongSuk , Kim SeungMin
Published: April 2018

This study analyzed the elementary mathematics textbooks and teachers’ manuals in terms of an analytical-methodological approach to explore how the properties of numbers and operations and the relationship between operations were represented from the perspective of generalized arithmetic. As a result of the analysis, there was a big difference between grades regarding when to deal with such properties and relationships. A noticeable aspect was that the thinking process of generalization was not fully implemented, even though the result of generalization was represented. In order to increase the opportunities of algebraic thinking for elementary school students, the suggestions drawn from the results of this study include that textbooks and teachers’ manuals need to describe the process of generalization in a more explicit way, present the properties and relations in a consistent way, and consider when to deal with generalization across grade bands and how to present tailored to the developmental characteristics of students.

Authors:   The Korea Society Of Educational Studies In Mathematics, Kim Hye Mi , Han Sun Young
Published: April 2018

The aim of this study was to develop an assessment tool that can be used to evaluate the mathematical problem solving competency. First, a literature research was conducted to document the concepts of the competency, the problem solving competency, the mathematical problem solving competency and the relevant sub-elements. Second, a survey was conducted targeting the students having excellent mathematical problem solving competency to examine the behavioral examples of mathematical problem solving competency, and provisional preparatory questions were deducted. Third, content validity verification was performed twice by the mathematics education experts and teachers to verify the derived preparatory questions. The face validity verification was conducted targeting the first-grade students of high schools located in Seoul. Finally, preliminary survey and the main survey was conducted. The descriptive statistical analysis(average, standard deviation, skewness, and kurtosis), correlation analysis between the questions and total scores, reliability analysis, and exploratory factor analysis were performed to analyze the preliminary survey. And for the main survey analysis, the confirmatory factor analysis, which was about the verification of reliability and validity of the latent variables and measured variables, was performed to evaluate the suitability of measurement model. The construct validity was derived by reviewing the convergent validity and discriminant validity. In conclusion, the seven subordinate factors of mathematical problem solving competency, including the problem understanding, planning, strategy seeking, plan execution and self-questioning, cooperative problem solving, mathematical modeling, and problem making, were extracted. Also, a total of 40 questions were developed to be able to evaluate the factors. Hence, the mathematical problem solving competency assessment tool developed in this study could provide a practical basis for further studies and education fields.

Published: April 2018

A fin de contar con una línea base de información para monitorear los impactos potenciales del cambio climático en los ecosistemas forestales, se establecieron y caracterizaron nueve Parcelas Permanentes de Muestreo (PPM) de una hectárea en el Parque Nacional Izta-Popo, México, que se distribuyeron en tres zonas: Paso de Cortés, Llano Grande y Tláloc en las tres cotas altitudinales de 3 500, 3 700 y 3 900 m dentro de bosques de Pinus hartwegii. Para el arbolado mayor a 7.5 cm de DAP, se estimaron parámetros dasométricos de área basal, volumen, biomasa y carbono. Mediante el modelo estadístico del diseño anidado se detectaron diferencias significativas entre zonas al 0.05 para el volumen, mientras que para el área basal y la biomasa las posibles diferencias pueden ocurrir al 0.1. No obstante, a través del ANOVA que consideró una combinación lineal de todas las variables, se confirmaron diferencias significativas entre zonas con una alfa del 0.05. La condición dasométrica del arbolado presente en las PPM establecidas en el Parque Nacional Izta-Popo sugiere una estructura del bosque de Pinus hartwegii con poca regeneración natural y presencia de plagas y enfermedades, que en el mediano plazo pueden incrementarse debido a la madurez y la falta de manejo de los ejemplares. El área relacionada con las parcelas no ostenta cambios de uso del suelo, por lo que es un sitio recomendable para el monitoreo y su relación con las variaciones climáticas.

Los recientes avances en las tecnologías de sensores remotos han hecho posible que algunas características físicas de la vegetación sean estimadas con mayor rapidez y permiten distinguir las especies del arbolado urbano y analizar su distribución en el espacio y tiempo, lo cual resulta en mejoras notables de precisión cartográfica. En el presente trabajo se utilizaron datos de LIDAR aéreo para estimar la altura y el diámetro de copa de árboles individuales en un área urbana al sur de Monterrey a fin de diseñar un método eficiente para cartografiar el arbolado de las ciudades. Se usaron dos técnicas de extracción: 1) diseño de filtros semiautomatizados para los puntos asociados a la vegetación y 2) uso de líneas de contorno sobre un modelo digital de superficie. Los resultados se verificaron con la información de campo que se obtuvo durante el mismo periodo mediante el empleo de métodos tradicionales de medición forestal, lo que se realizó en 57.80 ha y se contabilizaron 2 575 árboles. El mapeo de las copas fue eficaz para 74.7 % de los individuos y se registró 6.4 % de error de medición en el geoposicionamiento e inventario. Se observó una eficacia similar entre el muestreo en campo y la nube de puntos de LIDAR aéreo (xy=0.70m; z=0.10 m), de acuerdo con el análisis de regresión lineal de alturas (R2= 0.885) y del ancho de copa (R2= 0.902). Las mejores estimaciones fueron en Quercus shumardii (95 %) y Quercus vaseyana (94 %).

Aunque Touraine ha sostenido que el sujeto se constituye colectivamente, la producción última del sentido la hace residir en entidades de conciencia identificadas consigo mismas, es decir, en individuos; de este modo, se ha conectado con cierto izquierdismo latinoamericano y su invocación a “sujetos de derecho” titulares de una “soberanía” que, en última instancia, supone el “control consciente sobre un sí mismo”. Así, los axiomas de la política liberal individualista pasan a constituir el fondo constante sobre el cual se efectúan hasta los cambios sociales más profundos.Palabras clave izquierda / derechismo / accionalismo / política / imperio / movimientos sociales.Abstract:Although Touraine has maintained that the subject is constituted collectively, the last production of sense resides in identified organizations of conscience within themselves, that is to say, in individuals; this way, it has connected with certain Latin American leftist orientation and its invocation to “ subjects of right” entitled to a “sovereignty” that, in last instance, supposes the “conscientious control on itself”. Thus, the axioms of the individualistic liberal policy happen to constitute the constant bottom on which take place the deepest social changes.Key words Left / right / factionalism / politics / empire / social movements

Authors: Timmermann Freddy
Published: April 2018

El autor aborda la temática denominada “el factor Pinochet”, más allá de su presencia física directa en los espacios de poder, sino más bien como una herencia política de su régimen dictatorial, en alianzas con las élites políticas y económicas de Chile. Como se señala, pareciera ser que hemos heredado una cultura autoritaria que traspasa las fronteras temporales del período del régimen militar y se instala en una debilitada democracia actual.Palabras clave Pinochet / autoritarismo / élites / poder / políticaAbstract:The author approaches the topic denominated “Pinochet factor”, beyond his direct physical presence in the spaces of power, but rather like a political inheritance of his dictatorial regime, in alliances with the political and economic elites of Chile. As it is shown, it seemed to be that we have inherited an authoritarian culture that transfers the temporary borders of the period of the military regime and it settles in a weakened present democracy.Keywords Pinochet / authoritarianism / elites / power / politics

ResumenEl artículo que se presenta a continuación da cuenta de las complejas relaciones entre escuela, subculturas y juventud. En esta tríada se conjuga un conjunto de aspectos que hacen referencia a los procesos pedagógicos, a la función docente y a las clásicas funciones que cumple la escuela, a saber, la certificación del conocimiento, la función educativa propiamente tal y la función de socialización.

It is built from the justifications that support the need for better ways of representing disadvantaged groups in general and women in particular as a requirement for democracy and social justice. The essay debates affirmative action and some false assumptions around it, arguing for gender quotas as the strongest mechanism to achieve a definite inclusion of women into politics.Key words: Gender Politics, Affirmative Action, Representation.ResumenEl siguiente ensayo presenta una mirada a algunos de los enfoques teóricos que dictan el debate de la participación y representación política de las mujeres, teniendo como hilo conductor la pertinencia de las estrategias de acción afirmativa.

El ensayo debate sobre la acción afirmativa y algunos de los supuestos que rodean este concepto y presenta a las cuotas de género como el mecanismo más fuerte para alcanzar una inclusión permanente de las mujeres en la política.Palabras Claves: Género y Política, Acción Afirmativa, Representación.
