Fuentes sobre el origen del concepto de “otaku”
Authors: Rodríguez Cruz Jorge
Published: July 2021

El proceso de asociación del concepto de ‘otaku’ con la imagen estereotipada que la sociedad japonesa ya tenía de ese grupo, o lo que es lo mismo, la génesis de la definición actual del término, se desarrolló a lo largo de los años ochenta hasta que terminó popularizándose a finales de la década, gracias al infame “incidente Miyazaki”. Dos artículos publicados en revistas dedicadas a fans del anime a principios de esa década resultan clave para la comprensión de este proceso: por un lado, la definición que  Shirakawa Shōmei hizo en 1981, como parte de una guía para nuevos estudiantes, de aquellos jóvenes que pertenecían a los clubs de cultura escolares; y por otro, el reconocido como primer texto que acuña el término ‘otaku’ en asociación a una imagen similar a la ofrecida por Shirakawa, el artículo publicado en dos partes en el verano de 1983 por Nakamori Akio. En este trabajo se presenta una traducción inédita al español realizada directamente desde los textos originales, así como una breve reseña sobre sus autores y un análisis sobre la relevancia de estos.
Japón en Cuba. El fenómeno del manga y otros espacios de cooperación en materia cultural
Authors: Fabeloc Sunamis
Published: July 2021

En la actualidad resulta particularmente significativa la influencia cultural nipona en Cuba. Este ha sido un proceso acumulativo que ha evolucionado en diversos tiempos, niveles y esferas, pero que sin dudas ha acercado a ambos pueblos. Resalta la influencia del manga japonés, una de las que está entre las grandes tradiciones de historietas a nivel mundial. En la isla caribeña, entre las nuevas generaciones, puede identificarse la emergencia de un grupo de creadores y aficionados a la cultura japonesa que han incorporado de manera empírica esta impronta a sus producciones y, por tanto, demandan espacios de encuentro e intercambio cultural. En tal sentido, se evidencia la factibilidad de explorar nuevas áreas de cooperación e interés común, así como de potenciar las ya existentes

Published: July 2021

La historia política de Japón en el siglo XX, fue testigo del nacimiento, a gran escala, de los movimientos de izquierda y en particular las acciones de la izquierda revolucionaria en la Posguerra. Lo cual marcó, sin lugar a duda, el tránsito de la resistencia organizada contra las gestiones de política exterior del gobierno japonés. Al mismo tiempo, se observó el desmantelamiento de esas acciones populares dentro del proceso de conversión de Japón como potencia económica. Ferran de Vargas realiza un análisis preciso sobre ese periodo histórico que es necesario recordar para comprender los cimientos, un tanto ocultos, en los que se edificó el Japón contemporáneo.

Authors: ÖZBERK Eren Halil , TÜRK KURTÇA Tuğba
Published: July 2021

Procrastination behaviour occurs when the person is obligated to do an activity, even they are not motivated to carry out the activity within the expected time frame. Literature studies define four types of procrastination: academic, decisional, life routines, and neurotic. This study focuses on academic procrastination in higher education. Academic procrastination is mainly related to delaying academic tasks such as handing in assignments and term papers or preparing for the exams at the last moment. This study compares Turkish and international students' academic and general procrastination profiles using latent profile analysis. For this purpose, latent profiles were estimated to reveal how students from different cultures are grouped according to academic and general procrastination behaviour. A total of 691 undergraduate students, 52.4% (361) Turkish and 47.6% (330) of international students registered for an academic program in higher education participated in the study. Results indicated that while Turkish students for three latent profiles defined as Tending to enjoyable Works, Neither Lessons nor Other Works and Ambition for Academic Success. On the other hand, International students only fit two latent profiles, which are defined as Academic Procrastination Tending to Enjoyable Works and Prioritizing Academic Tasks.

Authors: BENYACOUB Bouchra , AZIRAR Hanane
Published: July 2021

L’inclusion financière a suscité au cours de ces dernières années un intérêt grandissant de la part des organismes internationaux, des régulateurs du secteur financier ainsi que des pouvoirs publics. Cette tendance traduit une prise de conscience du  rôle que peuvent jouer les services financiers dans la promotion d’une croissance inclusive et la concrétisation des objectifs de développement durable notamment en favorisant la réduction de la pauvreté et des disparités entre les genres. Au Maroc plusieurs stratégies ont été mises en place pour réduire les inégalités d’accès aux services financiers. Avec le lancement du paiement mobile en 2016, les pouvoirs publics ambitionne de généraliser l’accès des populations défavorisées aux services financiers. L’objet de  cette étude est d’évaluer l’effet  du mobile money sur la réduction des inégalités d’accès aux services financiers numériques. L’éstimation d’un modèle composé de 7 variables sur un échantillon de 156 personnes au Maroc révèle que le mobile money réduit significativement les inégalités d’accès aux services financiers. En effet, il ressort que deux variables ont un effet significatif  sur la réduction des inégalités d’accès aux services financiers à savoir l’âge et le revenu. Il ressort aussi que le manque de confiance, de provision et d’éducation financière jouent un rôle important dans l’exclusion financière.

A Review on Recent Developments for the Cure of Salmonella Enterica Serovar Typhi, the Causative Agent for Typhoid Fever
Authors: Kanwal Muqadas , Waheed Fadia , Shahzadi Hafsa , Shahbaz Muhammad , Noor Ahsan
Published: July 2021

Salmonella enterica typhi is typhoid or enteric fever agent which is a serious water-borne disease and is a human host restricted organism. So, an important cause of death in underdeveloped countries, typhoid fever is a public health concern. Worldwide, 15-30 million people suffer from this disease every year, causing more than 200,000 deaths. However, several lines of evidence suggest that the advent of multidrug-resistant non-typhoidal strains of Salmonella has an important impact on the effectiveness of current strategies, including reductions in the effectiveness of early empirical treatment for controlling and managing foodborne diseases. Recent studies show more than 2000 strains of salmonella bacteria with around 100 strains connected to human infection - with myriad common strains from Salmonella Heidelberg to Typhimurium to Salmonella infantis. The multi-medicinal strain S. Typhi H58 has developed into the main circulating strain in many parts of the world, and an extensively drug-resistant (XDR) subclade has been recently found. Most of the people agree that the most effective way to control infection is to vaccinate susceptible populations. The commercially available live attenuated (Ty21a) vaccine, on the other hand, is not recommendable for children under the age of six, whereas the poor long-term efficacy of Vi-polysaccharide-based vaccine against typhoid fever. Furthermore, there are no vaccines available to protect against S. para typhi infection. Subsequently, a new formulation is urgently needed that can provide long-term protection against both pathogens while healthy for all age groups. Pakistan is the first country in the world to incorporate the WHO-recommended conjugate vaccine into its routine typhoid immunization program (2019). As a result, the purpose of this review is to describe the various diagnostic procedures for typhoid fever diagnosis and cure development. This article addressed some of the elements and components required for the implementation of typhoid vaccine.
With an analysis of past and current enteric fever vaccines in progress as well as the ethical issues relevant to CHIM in typhoid vaccine efficacy research, we have combined the new methods to predict typhoid burden and vaccines impact.

Authors: Rizvi Fariha Zakria , Faisal Muhammad
Published: July 2021

Bioremediation refers to the use of microorganisms to reduce or eliminate contaminants from water and soil. In the current research, different bacterial strains were screened for their chromate and arsenate reduction potential. For the removal of arsenic, eight arsenic resistant bacterial strains AsK03, AsK04, AsK06, AsK07, AsK08, AsK09, AsK15 and AsK18 and for chromium removal, eight chromium resistant bacterial strains CrK02, CrK08, CrK12, CrK14, CrK16, CrK19, CrK20 and CrK21 were isolated and selected, respectively, from several contaminated soil and water samples taken from tanneries located in Kasur. Resistance to chromium and arsenic was shown by all the strains on nutrient agar at preliminary concentration of 500 µg ml-1 . The maximum tolerable concentration (MTC) of these isolates was also studied. It was found that for arsenic resistance, two strains AsK04 and AsK09 had highest MTC of 100 mg ml-1 , AsK18 had 75 mg ml-1 , AsK03, AsK06 and AsK15 had 50 mg ml-1 and AsK07 and AsK08 had 45 mg ml-1 of Na2HAsO4 concentration. Similarly, chromium resistant strains were also checked for their MTC against K2CrO4. Here MTC of CrK16 and CrK19 were highest (75 mg ml-1 ), CrK08 and CrK12 were 50 mg ml-1 , CrK02 and CrK20 were 25 mg ml-1 , CrK14 and CrK21 had least MTC of 7.5 mg ml-1 . Fifteen of the bacterial strains were genetically identified by sequencing of 16S rRNA gene. BLAST analysis revealed that the seven strains are homologous to genus Bacillus.
Peroxisome Proliferator-Activated Receptors (PPARS)
Authors: Sumbal Sarwar  , Shabana
Published: July 2021

Peroxisome proliferator-activated receptors are a group (PPARs) of transcription factors whose differential distribution in different tissues, including adipocytes, hepatocytes, musclesand endothelial cells lead to different clinical outcomes. They are called lipid and insulin sensors due to the important role in lipid and glucose homeostasis. They are mainly of threetypes; 1) PPAR? which influences fatty acid metabolism and its activation lowers lipid levels,2) PPAR? causes fatty acid oxidation in skeletal and cardiac muscles, as well as regulatesblood glucose and cholesterol levels and 3) PPAR? which is mostly involved in the regulationof the adipogenesis, energy balance, and lipid biosynthesis. The expression of these receptorsis influenced by many natural and synthetic ligands. Realistic data on the expression andfunction of natural PPAR agonists on glucose and lipid metabolism are still missing, mostlybecause the same ligand influences several receptors and a number of reports have providedconflicting results. The current minireview focuses on the structure, functions, types andligands of the PPAR.

Authors: Nawaz Shahid , Saleem Maira
Published: July 2021

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has emerged as a global pandemic causing coronavirus disease 2019 (COVID-19). It was firstly reported in Hubei province in the People’s Republic of China and spread worldwide quickly. The COVID-19 affects every person differently, from mild to life-threatening symptoms (Nawaz, 2020), along with other bacterial or fungal co-infections (CDC., 2021). The COVID-19 affected patients are prone to develop severe opportunistic infections (Salehi et al., 2020). The immune system of SARS-COV-2 infected patients becomes vulnerable to these opportunistic infections if some comorbidities (diabetes, pulmonary disease) or immunocompromised conditions (steroid therapy, hospital stay, and ventilation) are present. The development of infections such as Pneumocystis jiroveci pneumonia, bloodstream candida, pulmonary aspergillosis, and oropharyngeal candidiasis have been reported in SARS-CoV-2 infected patients (Moorthy et al., 2021). A few case reports of rhino-orbital mucormycosis in COVID-19 have been reported (Mehta et al., 2020). One such study was reported by (Sen et al., 2021), in which they presented a series of six cases of COVID-19 disease with rhino-orbital mucormycosis. Only one patient in this series had concurrent COVID-19 and mucormycosis at hospital admission, while five patients developed mucormycosis during treatment for COVID-19. Recent studies in Pakistan have reported an increased number of cases of mucormycosis, also known as “black fungus” in COVID-19 patients (The News., 2021).
MITOGEN ACTIVATED PROTEIN KINASE: FUNCTION AND RESPONSES TO DIFFERENT STRESSES IN PLANTS
Authors: Khan Sara , Iqbal Nadia , Deeba Farah , Jabeen Raheela
Published: July 2021

Mitogen Activated Protein Kinase (MAPK) pathway is the most commonly studied signaling mechanisms, consisting of different groups of protein kinases that participate in regularly connecting interpretation of external stimuli that can change in gene expression or cellular organization within eukaryotic systems. The MAP kinase pathways functions in plants cell signaling (intra- and extra). MAPK cascades follow a response system. MAP kinases are the component of kinase constituents that deliver signals from sensors to responders in eukaryotes including plants. Several pathways are activated under different environmental stresses. Stimulating agents may be biological (biotic) like microbial infections or environmental (abiotic) like temperatures threshold, high salt concentration, drought, heavy metal, Ultra-violet radiation, ozone gases and reactive oxygen species (ROS). The involvement of MAPK signaling pathway in different stresses has been widely studied. In this review we also try to highlight MAPK cascades, its regulation, functions and recent findings in various cellular processes against stress conditions.
FUNCTIONAL STUDY OF WRKY PROTEIN IN DIFFERENT PLANT AND NON-PLANT SPECIES AND ITS RESPONSE UNDER BIOTIC AND BIOTIC STRESSES
Authors: Mujahid Naila , Iqbal Nadia , Zain Maryam , Deeba Farah
Published: July 2021

WRKY transcription factors belong to one of the biggest superfamilies of proteins in higher plants. WRKY proteins participate in plant growth for instance, gamete formation, seed germination and are also responsive to different types of environmental cues including abiotic and biotic stresses. The DNA-binding site of WRKY factors is well established which interact with W?box (TGACC(A/T)) located in the promoter of their target genes and promote the activation or repression of the expression of those genes to control their response against stresses but it remains difficult to establish the functions of every family members to control particular transcriptional programs during development or in response to environmental signals. This review summarizes the recent progress made in unraveling the various WRKY protein-controlled functions under different environmental stresses.

Objective: The objective of our study was to explore student’s perception of the educational environment in their respective medical colleges

Materials and Methods: A cross-sectional study was conducted at two medical colleges (one public sector and one private-sector medical college), both affiliated with Khyber Medical University, Peshawar from January 2020 to March 2020. DREEM was used to measure the educational environment of both public sector and private sector medical colleges.

Results: The overall mean score with standard deviation was 113± 22 SD for private medical college and 109 ± 25 SD for public sector medical college, which means more positive than negative perception. Private sector college overall score was better than public sector college but with no significant difference. Private sector medical college score was better in all DREEM subscales except Students’ Academic Self-Perception in which public college scored 18± 5 and private college scored 16± 5.

Conclusion: There is a significant margin for improvement for all domains of the educational environment in both public and private sector medical colleges, especially the low scores in the domain of Students’ Social Self Perceptions need attention.
Questaal: A package of electronic structure methods based on the linear muffin-tin orbital technique
Authors: Jackson Jerome
Published: July 2021

Questaal is a set of codes developed for calculating the electronic structure of materials from first principles. Developed by Mark van Schilfgaarde and his collaborators, Questaal descends from the work of Ole K. Andersen and his group in Stuttgart during the 80's on the linear muffin-tin orbital (LMTO) method. This is an atom-centred basis set that is by construction particularly efficient for solving the band structure problem. As Questaal has evolved, a variety of codes and techniques aimed at addressing both different material problems and implementing different levels of theory have been developed. These include methods based on the atomic sphere approximation, where a simplified description of the crystal potential can be exploited to facilitate calculations that are scarcely possible otherwise: recent calculations of the supercurrent in Josephson junction devices formulated in terms of non-equilibrium Green's functions calculated ab initio (using density functional theory) demonstrate that this method continues to be extremely useful. At the other end of the spectrum, highly accurate calculations for more basic material studies can be conducted using Questaal's implementation of quasiparticle self-consistent GW (QSGW). QSGW is a way to achieve a measure of self-consistency in Hedin's perturbative GW method, thereby solving problems associated with the starting point dependence of GW and increasing its reliability significantly. QSGW provides a fully ab initio description of a broad range of materials that is generally much better than density functional theory or its common extensions (eg LDA+U). Questaal also includes the ability to extend QSGW to problems with stronger correlation by adding ladder diagrams (via the Bethe-Salpeter equation), or by coupling QSGW with DMFT, these representing the current state-of-the-art. This talk will describe the background, capabilities, some methodological aspects, and future directions of the Questaal project.

Authors: Shimizu Jarbas
Published: July 2021

Dado que en la mayoría de los casos los árboles forestales se plantan en su estado natural, un mejoramiento en cualquier de los factores relacionados con su crecimiento puede aumentar considerablemente su productividad. La preparación del sitio, la aplicación de fertilizantes, el drenaje y el riego son alguno de los factores del medio ambiente a los cuales los árboles son también muy sensibles. Estos factores deben mantenerse a niveles satisfactorios para asegurar una alta productividad. Entre los componentes genéticos uno debe reconocer la varianza genética aditiva y la varianza genética no aditiva. Dependiendo del monto de cada una en la variación genética total, uno puede determinar la estrategia más eficiente para maximizar la ganancia genética.

Se estudia el comportamiento de la densidad básica, la contracción tangencial, radial y longitudinal, con la posición radial, la altura y la orientación cardinal en madera de reacción y normal proveniente de un mismo árbol de Aromo australiano (Acacia melanoxylon R.Br.). La densidad básica aumenta de la médula a la corteza hasta 0,51 gr/cm³ y en madera normal 0,52 gr/cm³. La contracción radial y tangencial aumenta de la médula a la corteza. Con la altura, la contracción tangencial disminuye. En promedio la contracción radial y tangencial de la madera de reacción superan a la contracción de la madera normal. La contracción longitudinal en estado anhidro de la madera de reacción es 0,28% y en madera normal es 0,35%. El coeficiente de contracción unitario y el punto de intersección de la contracción, son levemente superiores en la madera de reacción.

Published: July 2021

El Instituto Forestal en su intento de productos forestales está investigando otras especies de rápido crecimiento y buenas perspectivas económicas, que sean alternativas al Pino radiata. En Chile, Acacia melanoxylon ha presentado una excelente adaptación desde la Región del Maule a la Región de Los Lagos, con desarrollos muy buenos en sitios forestales. A pesar de esto, se desconocen las técnicas de viverización, de plantación y de manejo, su rendimiento y la rotación del aromo australiano. El objetivo central de este artículo es entregar antecedentes generales sobre la especie Aromo australiano (Acacia melanoxylon).

Se describe la anatomía y desarrollo de flores, frutos y semillas de boldo (Peumus boldus Mol.) con el fin de proporcionar nuevos antecedentes que contribuyan a comprender los mecanismos de latencia que presentan las semillas de esta especie. El material vegetal se recolectó entre fines de invierno y mediados de verano, en la Región Metropolitana de Santiago. Las flores y frutos se infiltraron en JB-4 (Polyscience, Inc.) y se cortaron con ultramicrótomo (2-4 µm espesor) ; las semillas se incluyeron en parafina (Histosec) y se cortaron con micrótomo rotatorio (8-10 µm).
Efectos de diferentes métodos de plantación en el desarrollo inicial de Eucalyptus camaldulensis, E. cladocalyx y E. sideroxylon en la zona árida de Chile
Authors: Wrann H. Johannes
Published: July 2021

En la zona árida de Chile, en la provincia de Choapa, Región de Coquimbo con alrededor de 215 mm de precipitación anual, se probaron tres tratamientos de preparación de suelo, con y sin aplicación de fertilización y control de malezas, con el fin de determinar el efecto en el establecimiento de plantaciones de Eucalyptus camaldulensis, E. sideroxylon y E. cladocalyx. En el momento de la evaluación las plantaciones habían cumplido la edad de 4-3 y 2 años respectivamente. La fertilización afecta positivamente el desarrollo de las plantas, si se aplica después del control de malezas. Los mejores resultados se obtuvieron al emplear como preparación del suelo una combinación de subsolado (en el caso de E. camaldulensis y E. sideroxylon) y surco (en el caso de E. cladocalyx), con la aplicación de fertilizante (NPK) con control de la vegetación competidora, lográndose respuestas positivas a pesar de las condiciones difíciles de la zona.

Authors: Grosse Werner Hans
Published: July 2021

Una vez establecida la regeneración de las especies arbóreas, se debe realizar una serie de intervenciones silvícolas que se orientan según el objetivo de producción del rodal. Antecedentes en este sentido para especies del género Eucalyptus aún son escasos en Chile. Por este motivo dentro del programa para el manejo de especies del género Eucalyptus del INFOR, se incorporó un ensayo de raleo que permita encontrar respuestas para diversas alternativas de manejo. Esto significa probar esquemas de manejo para producir, en distintas proporciones, desde madera para pulpa hasta trozas para chapa y madera aserrada, considerando un número de variantes intermedias.

Astroblastoma is an uncommon, controversial neoplasm of the Central Nervous System (CNS) emerging from the glia. “Astroblastoma” as a terminology was initially coined in 1924 for a tumefaction characteristically emerging as a unique astrocytic glioma comprised of tumour cells configuring perivascular pseudo-rosettes and appearing immune reactive to Glial Fibrillary Acidic Protein (GFAP). Bucy and Bailey in 1930 delineated diverse macroscopic and microscopic features of the neoplasm with description of individual astroblasts as unipolar cells with broad “feet” amalgamating adjacent to vascular articulations. Subsequently in 1933, Cox categorized astroblastoma as a neoplasm transitioning between astrocytoma and glioblastoma multiforme.

Tüm dünyada olduğu gibi ülkemizde de verimsiz orman alanı önemli ekonomik ve sosyo-kültürel problemlerden biridir. Birleşmiş Milletler Gıda ve Tarım Teşkilatı’nın 2015 yılı verilerine göre  1990 yılında 4 milyar 128 milyon hektar olan orman varlığı, 2015 yılında 3 milyar 999 milyon hektara düşmüş ve 2010-2015 yılları arasında ise dünya genelinde yıllık ortalama 3 milyon hektar orman alanı elden çıkmıştır. Ormansızlaşma süreci dünya genelinde devam etmektedir ve bu sürecin özellikle doğal ormanlarda meydana geldiği bilinmektedir. Orman varlığımıza ilişkin olarak gerçekleştirilen güncel 2019 yılı envanterine göre 22.74 milyon hektar büyüklüğündeki Türkiye ormanlarının %42.2’si (9.6 milyon hektar) bozuk orman yani ağaçlandırma çalışmalarına konu orman niteliğindedir. Bu alanlara, orman yangını, usulsüz faydalanma, kuraklık gibi nedenlerle bu verimsiz orman alanlarına yenileri eklenebilmektedir. Bu ormanların ıslahında ağaçlandırma, rehabilitasyon ve gençleştirme gibi silvikültürel faaliyetler en önemli uygulamalardandır. Derleme niteliğindeki bu makalede, ülkemizdeki ağaçlandırma faaliyetleri diğer orman tesisleri ile birlikte güncel ormancılık envanteri ışığında alansal olarak irdelenerek, ağaçlandırma uygulamalarına katkı sağlanması amaçlanmıştır.

O presente artigo tem como objetivo apresentar e caracterizar as pesquisas na Educação Física no Ensino Médio Noturno, a partir das publicações feitas em cinco periódicos nacionais da Educação Física entre os anos de 2009 a 2019. O estudo torna-se relevante pela importância do uso da pesquisa Estado da Arte na Educação Física, na qual possibilita realizar um mapeamento a partir das publicações-científicas sobre determinada temática de estudo, com isso podemos observar como se encontram os principais temas. Diante desse contexto, questiona-se a possibilidade de novos estudos sobre a Educação Física no ensino médio noturno. Deste modo, foram analisados 3.319 artigos em cinco períodos da área, na qual obtivemos 55 artigos sobre a Educação Física no ensino médio, e a penas 1 sobre o ensino médio noturno. Ao final, foi possível concluir que os estudos relacionados a Educação Física no ensino médio noturno aponta uma desvalorização e a pouca representação nesse âmbito de ensino, na qual correspondeu que 1,65% fazem referência a temática de estudo. Entretanto, percebe-se uma grande discrepância sobre os outros assuntos pesquisados no meio acadêmico-científico da Educação Física. Logo, a elaboração do Estado da Arte, promoveu a realização desse mapeamento das publicações sobre a temática, na qual foi dividida em oito categorias e com suas subcategorias. Estudos como este são relevantes pois visam demarcar e caracterizar melhor como se encontra a Educação Física no ensino médio noturno para viabilizar melhor compreensão dos impactos que a pesquisa pode ter sobre este nível de ensino.
