Barriers to entry of housing affordability are not only existed in urban but also in rural areas. This condition makes rural households difficult to obtain their own house. However, it is still common for them to ask help from parents, in term of financial support or buy the house for them. The purpose of this paper aimed at understanding the phenomenon of society in the rural area to meet their need for house ownership. This research used the descriptive method, employed 15 participants in the Village of Olak-Alen, District of Selorejo, Regency of Blitar, Indonesia. The results of this research showed that newly formed households find their most significant obstacle to own house is inadequate income. Their low income is majorly caused by lack of financial literacy and insufficient work experience.

Antimicrobial Capacity of Plant Polyphenols against Gram-positive Bacteria: A Comprehensive Review
Authors: Álvarez-Martínez Francisco Javier , Barrajón-Catalán Enrique , Encinar José Antonio , Rodríguez-Díaz Juan Carlos , Micol Vicente
Published: October 2018

Background:

Multi-drug-resistant bacteria such as Methicillin-Resistant Staphylococcus aureus (MRSA) disseminate rapidly amongst patients in healthcare facilities and suppose an increasingly important cause of community-associated infections and associated mortality. The development of effective therapeutic options against resistant bacteria is a public health priority. Plant polyphenols are structurally diverse compounds that have been used for centuries for medicinal purposes, including infections treatment and possess, not only antimicrobial activity, but also antioxidant, anti-inflammatory and anticancer activities among others. Based on the existing evidence on the polyphenols’ antibacterial capacity, polyphenols may be postulated as an alternative or complementary therapy for infectious diseases.

Objective:

To review the antimicrobial activity of plant polyphenols against Gram-positive bacteria, especially against S. aureus and its resistant strains. Determine the main bacterial molecular targets of polyphenols and their potential mechanism of action.

Methodology:

The most relevant reports on plant polyphenols’ antibacterial activity and their putative molecular targets were studied. We also performed virtual screening of thousand different polyphenols against proteins involved in the peptidoglycan biosynthesis to find potential valuable bioactive compounds. The bibliographic information used in this review was obtained from MEDLINE via PubMed.

Results:

Several polyphenols: phenolic acids, flavonoids (especially flavonols), tannins, lignans, stilbenes and combinations of these in botanical mixtures, have exhibited significant antibacterial activity against resistant and non-resistant Gram-positive bacteria at low μg/mL range MIC values. Their mechanism of action is quite diverse, targeting cell wall, lipid membrane, membrane receptors and ion channels, bacteria metabolites and biofilm formation. Synergic effects were also demonstrated for some combinations of polyphenols and antibiotics.

Conclusion:

Plant polyphenols mean a promising source of antibacterial agents, either alone or in combination with existing antibiotics, for the development of new antibiotic therapies.
Electrocardiogram Fiducial Points Detection and Estimation Methodology for Automatic Diagnose
Authors: Yáñez de la Rivera René , Soto-Bajo Moisés , Fraguela-Collar Andrés
Published: October 2018

Background:

The estimation of fiducial points is specially important in the analysis and automatic diagnose of Electrocardiographic (ECG) signals.

Objective:

A new algorithm which could be easily implemented is presented to accomplish this task.

Methods:

Its methodology is rather simple, and starts from some ideas available in the literature combined with new approachs provided by the authors. First, aQRScomplex detection algorithm is presented based on the computation of energy maxima in ECG signals which allow the measurement of cardiac frequency (in beats per minute) and the estimation of R peaks temporal positions (in number of samples). From these ones, an estimation of fiducial points Q, S, J, P and T waves onset and offset points are worked out, supported in a simple modified slope method with constraints.

The location process of fiducial points is assisted with the help of the so called curvature filters, which allow to improve the accuracy in this task.

Results:

The procedure is simulated in Matlab and GNU Octave by using test signals from the MIT medical database, Cardiosim II equipment patterns and synthetic signals developed by the authors.

Conclusion:

One of the novelties of this work is the global strategy. Also, another significant innovation is the introduction of the curvature filters. We think this concept will prove to be a useful tool in signal processing, not only in ECG analysis.

Lágrimas de Heraclito: a unidade criativa de sentimento e pensamento na obra de Padre António Vieira
Authors: Abreu Tiago Eric de
Published: October 2018

Refletindo sobre a emotividade humana vinculada à escritura literária, o presente artigo apresenta questões suscitadas pela leitura da obra de Padre António Vieira “Lágrimas de Heraclito”, que versa sobre o riso e o pranto, expressando o paradoxo existencial das emoções. Apoiando-se nos novos paradigmas do conhecimento, emanados da obra do pensador indiano Amit Goswami, o presente estudo aborda o tema considerando a consciência como sendo a unidade de vivência e comoção. A integração de sentimento e pensamento na criatividade poético-literária conduz a considerações sobre o fenómeno emocional e suas implicações éticas para a consciência. Considerando que no paradigma integrativo convergem múltiplos campos de estudos em humanidades, o presente artigo elabora uma reflexão sobre as expressões anímicas intuitivas e simbólicas da criatividade emocional na arte literária.
‘A FONDNESS FOR BEING SAD’: SOME PORTUGUESE SOURCES FOR ELIZABETH BARRETT BROWNING’S POETICS OF MELANCHOLY IN SONNETS FROM THE PORTUGUESE (1850)
Authors: Guimarães Paula
Published: October 2018

In seeing melancholy as the antithesis of poetic creativity, the Victorians often broke with the traditional Renaissance and Romantic attitudes of equating melancholy moods with artistic or poetic genius. This article proposes to explore how, initially viewed as an emotional and ‘depressed’ woman poet, Elizabeth Barrett Browning tried to resist and escape the sickening disempowerment or abandonment which had affected poets such as Felicia Hemans and Letitia Landon, and engage in a new poetics of melancholy in Sonnets from the Portuguese (1850). It demonstrates how the poet plays this poetics out in most of her later sonnets, where she indeed attempts to prove that good poetry can be written without melancholy, even if she herself does not always succeed in this deliberate rejection of ‘dejection’. The article thus intends to suggest, through a brief comparative analysis, that her apparently contradictory poetics of melancholy very probably derived from a specifically Portuguese poetic tradition, namely the ‘fondness for being sad’ of Luís de Camões, as well as the sorrowful love of Mariana Alcoforado’s epistles (1669) and of Soror Maria do Céu’s mannerist poems, an influence that is supported in the great similarity of motives and language that can be found in the respective texts.
Em busca da felicidade perdida: a astúcia e a arrogância no caminho da iluminação profana
Authors: Guilarduci Cláudio
Published: October 2018

O livro A cruzada das Crianças, lançado pela editora Pulo do Gato (2014), apresenta o poema homônimo de Bertolt Brecht (1948), acompanhado pelas ilustrações de Carme Solé Vendrell. A primeira publicação no Brasil do referido poema ocorreu em 1962 quando a editora Brasiliense lançou o álbum Cruzada de Crianças com gravuras de Gershon Knispel. O presente artigo elabora uma reflexão sobre os desenhos criados pelos dois artistas para apontar possíveis emoções e sentimentos vivenciados na história criada por Brecht. Para as discussões apresentadas partiu- -se do princípio de que o livro é um brinquedo que contém imagens e um universo de signos que pode narrar histórias. O caminho metodológico elaborado foi o da montagem por sobreposição tanto dos desenhos publicados em 2014 quanto daqueles publicados em 1962, a fim de revelar uma imagem dialética.
Sorrir à morte, com meia cara – memória e sentimento trágico em José Rodrigues Miguéis
Authors: Sever Cátia
Published: October 2018

O presente ensaio pretende apontar dados que permitam interpretar a narrativa de José Rodrigues Miguéis Um homem sorri à morte – Com meia cara como uma manifestação contemporânea do sentimento trágico. Para tal, propomos uma reflexão sobre categorias trágicas herdadas da Antiguidade Clássica, procurando mostrar a universalidade do sofrimento humano e das suas reacções face àquilo que nos ultrapassa. Através da leitura do texto migueisiano, procurar-se-á problematizar a noção de conflito enquanto elemento caracterizador da tragédia.

A meta é expor como Nava combina domínios discursivos literariamente moldados pela Estética, História e Psicologia para contar histórias de vida.
Ecos de A Costa dos Murmúrios em A Noite das Mulheres Cantoras, de Lídia Jorge. Esquecimento, memória e parábolas sociais
Authors: Simas-Almeida Leonor
Published: October 2018

O propósito deste ensaio é basicamente estabelecer paralelismos possíveis ou, se quisermos, relações de contiguidade entre dois romances de Lídia Jorge separados por várias décadas: A Costa dos Murmúrios (Jorge, 1998) e A Noite das Mulheres Cantoras (Jorge, 2011). Procuro demonstrar como ambos podem ser lidos como parábolas sociais — sobre temáticas bem diferenciadas — construídas sobre o binómio esquecimento / memória. A nível especificamente estrutural, os dois romances incluem cada um narrativas breves, representando o impulso de esquecer ou ocultar, seguidas de narrativas longas, cujo principal objetivo é lembrar ou desmascarar o que antes se escondera.

Authors: Mourão Luís
Published: October 2018

Os romances de Vergílio Ferreira fazem da nossa existência um romance que começa a ser escrito, obrigam a atravessar fronteiras (espaciais, filosóficas, genológicas), elucidam sobre a nossa condição de meta-animais físicos, dão-nos a linguagem segundo um modo análogo ao do jazz, ensinam que o amor vem só depois do fim e que o mundo é habitável se o olharmos a partir do impoder, dessa capacidade de levarmos o nosso abandono pela mão.

Authors: Wapwera Samuel D. , Dabis Nandi D. , Maigida Gerald T.
Published: October 2018

Most planning authorities in developing economies are not effective due to poor urban and regional planning systems making it almost impossible to control urban development and management of urban areas, leading to the haphazard urban development and poor management bringing about disproportionate distribution of resources in terms of basic infrastructure. It is against this backdrop that this paper seeks to examine the effectiveness of the institutional and technical planning frameworks in terms of Urban Development and Management (UDM) in Jos metropolis Nigeriaby identifying the factors that determines the effectiveness of the urban governance and management as well as identify and examining the urban planning system towards ensuring an effective urban controlled development and management in Jos metropolis Nigeria. The research approach adopted is qualitative and quantitative with deductive-inductive reasoning. The strategy used is “mixed method” and the instruments employed were questionnaires, face-to-face interviews, case studies documents reviewed with planning authorities in Jos Metropolis, Nigeria. The quantitative data sets obtained were analysed using Spearman ranks correlation coefficient (rho) and the qualitative data were analysed using thematic and content analysis. Statistically, the results showed that the components of the institutions (UG) and technical (UM) all have very strong statistical correlation. Based on the study results recommendations are proffered to practitioners, academia and policy makers.
LIMITING PROFILE OF AXISYMMETRIC INDENTER DUE TO THE INITIALLY DISPLACED DUAL-MOTION FRETTING WEAR
Authors: Li Qiang
Published: October 2018

Recently the final worn shape of elastic indenters due to fretting wear was analytically solved using the method of dimensionality reduction. In this paper we extend this model to dual-motion fretting wear and take into account that the indenter is initially pressed with constant indentation depth and moved horizontally with constant displacement. Two key parameters, the maximal indentation depth during oscillation and the stick area radius in the final state as well as the liming shape of indenter are analytically calculated. It is shown that the oscillation amplitudes and the initially indented or moved displacements have an influence on the final shaking-down shape.
SOLAR VACUUM TUBE INTEGRATED SEAWATER DISTILLATION - AN EXPERIMENTAL STUDY
Authors: Selimli Selcuk , Recebli Ziyaddin , Ulker Semra
Published: October 2018

The subject of this study is the seawater distillation process enhancement through integration of the solar vacuum tube into the system. Positive effects on the rate of distillated freshwater achieved by means of the enhanced system have been investigated experimentally. Experiments were done in the Turkish city of Samsun in the Black Sea region. A distillation pond setup having the volume of 0.015m3 and a water surface area of 0.24m2 was constructed. The distillation pond is covered with a condensation glass and also equipped with a 0.15m solar vacuum tube that is inclined at an angle of 30o to the ground, a feed water tank connected with a ball cock, and distillated fresh water tank. Experimental results have shown that the rate of distilled fresh water was enhanced for about 62.5% by integrating the solar vacuum tube and the natural distillation pond. Isolation of the condensation glass not only prevents the light transmission to the pond but also heat loss from the pond; hence the rate of the distillated fresh water is increased for about 137.5% due to the natural distillation.

INSTABILITY OF THE RAYLEIGH-BENARD CONVECTION FOR INCLINED LOWER WALL WITH TEMPERATURE VARIATION
Authors: Ayed Sadoon , Ilić Gradimir , Živković Predrag , Vukić Mića , Tomić Mladen
Published: October 2018

This paper deals with an analysis of a two-dimensional viscous fluid flow between the two parallel plates inclined with respect to the horizontal plane, where the lower plate is heated and the upper one is cooled. The temperature difference between the plates is gradually increased during a certain time period after which it is temporarily constant. The temperature distribution on the lower plate is not constant in x-direction, there is a longitudinal sinusoidal temperature variation imposed on the mean temperature. We have investigated the wave number and amplitude influence of this variation on the subcritical stability and the onset of the Rayleigh-Bénard convective cells, by direct numerical simulation of 2D Navier-Stokes and energy equation.

CHARACTERISTICS OF NATURAL FOCI OF TULAREMIA IN THE CRIMEA, THEIR POTENTIAL DANGER IN THE DEVELOPMENT OF THE EPIDEMIC PROCESS AND THE MAIN DIRECTIONS OF ITS PREVENTION
Authors: Pishchugin D. Yu. , Shubenkin S. G. , Tsintsadze O. G.
Published: October 2018

Geographical and climatic conditions of the Crimean peninsula, mammals of a particular ecosystem together with pathogens of the infection and a complex of their ectoparasites, contribute to the preservation of natural foci of tularemia and other natural focal infectious diseases on its territory. Epizootic activity of natural foci of tularemia has a welldefined periodicity and seasonality. Currently, natural foci of tularemia of the steppe type in the flat Crimea and forest type on the territory of the mountain-forest Crimea function. Three types of enzootic tularemia were identified. The epidemiological analysis of people with tularemia in the Crimea showed that its dynamics, level and distribution of cases in the administrative regions are determined primarily by the activity and duration of epizootics in natural foci located in the territories where tularemia is diagnosed. Prevention of diseases of people with tularemia in the Crimea, requires constant monitoring of the activity of natural foci of these infections, the timely detection of rodent epizootics, the study of their ectoparasites and their results, and the implementation of preventive measures.
CONCEPTUAL APPROACHES TO DEVELOPMENT OF MARINE MEDICINE IN ATLANTIC REGIONAL DIRECTION OF NATIONAL NAVAL POLICY OF THE RUSSIAN FEDERATION
Authors: Mosyagin I. G. , Boyko I. M.
Published: October 2018

The paper represents fundamental principles of concept of development of naval medicine in one of six main regional directions of national naval policy of the Russian Federation — Atlantic regional direction that includes the Atlantic Ocean, rims of the Black Sea, Azov Sea, Baltic Sea and Mediterranean Sea. Attention is drawn to the notion of «Marine medicine», its role and place in national health care is argued. The necessity of practical implementation of the Convention of the International Labor Organization, ratified by the Russian Federation in 2012, No. 186 «On labor in maritime navigation», is primarily emphasized, first of all, the creation of national and regional centers of maritime medicine, bringing various issues of medical provision of subjects of marine activity in line with international standards. The author notes that the problem of adaptation the national medical education to the international system of education in the field of maritime health care in the coming years will require the introduction of additions to the list of medical specialties and qualification requirements in the part related to marine medicine. It is on the basis of the national and regional centers of maritime medicine in the Russian Federation that it is proposed to organize training (postgraduate training, retraining) of the medical staff. It is noted that the Russian Federation, based on wide and positive experience of medical provision of seafarers in the Soviet Union, taking into account the organizational, scientific, methodological and practical features of the activities of the international centers of maritime medicine, will consistently and steadily develop the medical supply system of the state’s maritime power.

Higher order thinking skills are essential for student future. The 2013 Curriculum demands the existence of an evaluation instrument to train student higher order thinking, not only the thinking skill in the lower cognitive domain, but also in a higher domain. One of the efforts to enhance higher order thinking skills is to engage students with the questions integrated by cognitive C4-C6. This study analysed aspects of  higher order thinking in an evaluation instrument. This study used descriptive method by collecting evaluation instrument data used by teachers to evaluate a learning process. Evaluation instruments used by teachers at schools are still in the C1-C3 cognitive level (C1 47%, C2 47%, and C3 6%), the evaluation instruments are not eligible according to the standard applied. The skills demanded by the Fundamental Competency of the 2013 Curriculum. Higher order thinking skills of students are still relatively low, with the percentage mean of 52.03%. The low cognitive level obtained in the evaluation instrument used by the teachers is the reason of the low thinking level of the students.

The lack of student understanding on the topic of Biology presented by teacher may lead them towards a low achievement. This case could be seen from the low students’ average learning outcomes in the 7th grade Biology at MTsN Pakan Rabaa according to Minimum Completeness Criteria ( MCC ). One of the reasons is the traditional method of  question and answer applied by the teachers. Biology teachers only emphasizes learning on cognitive aspects. The low level of student learning outcomes are also determined by the students’ prerequisite knowledge. In order to solve this problem, the use of Problem Based Learning and initial ability learning model was applied. The purpose of this study is to evaluate the effect of Problem Based Learning and Initial Ability learning models based on the competence of the student learning styles of 7th Grade Biology at MTsN Pakan Rabaa in 2014/2015 academic year. This research applied quasi experiment which used the static group comparison design. The population was all of the 7th grade MTsN Pakan Rabaa students in academic year of  2014/2015. Sampling technique used was saturated sampling technique and the participants for  the experimental class were class VII A, with VII B as the control class. The research findings showed that (1) the students’ cognitive domain was significantly affected after the implementation of problem based learning model, except for those with high cognitive domain levels. (2) The students’ cognitive domain were improved significantly for both students with high and low ability. (3) The students’ psychomotor domain ability were improved significantly for both students with high and low ability (4) there was no interaction between the model of problem-based learning with the initial ability of students to learn biology cognitive competence of students.

Introducción: la cirrosis, entendida como un proceso dinámico y reversible, es el resultado final de las enfermedades hepáticas crónicamente progresivas de diferentes etiologías. Los métodos no invasivos basados en ecografía se han convertido paulatinamente en una herramienta diagnóstica útil en el estudio de las hepatopatías. Dentro de estos métodos, la elastografía en tiempo real, o Supersonic, de reciente introducción en nuestro medio, nos permite estudiar estos pacientes.Objetivo: evaluar el comportamiento de la elastografía en tiempo real en pacientes con cirrosis en un centro de atención de enfermedades hepáticas y digestivas en la ciudad de Bogotá.Materiales y métodos: estudio piloto retrospectivo de una cohorte con pacientes cirróticos con diagnóstico comprobado por biopsia hepática, imágenes, clínica o una combinación de estas.Resultados: se incluyeron 65 pacientes diagnosticados con cirrosis, la mediana de edad fue 58 años, 61,5% mujer y 38,5% hombre. Se encontró una mediana de rigidez hepática de 16,6 kilopascal (kPs) (RIQ de 13,9-19,5), con valor mínimo de 12 y un máximo de 30,5; sin una diferencia estadísticamente significativa entre mujeres y hombres dentro de los grupos con y sin biopsia (p = 0,64 y p = 0,26, respectivamente).Conclusión: los valores de la rigidez hepática de los pacientes cirróticos analizados en este estudio piloto se encontraron dentro de los reportados en los estudios iniciales de las pruebas a nivel internacional, por lo que se podría sugerir la realización de esta prueba no invasiva en pacientes con sospecha de cirrosis, evitando así las complicaciones de la biopsia hepática.

Introducción: la recurrencia de hepatitis autoinmune (HAI) postrasplante implica riesgo de cirrosis y pérdida del injerto. Se han propuesto factores de riesgo para su recurrencia, de los cuales pocos datos se conocen en pacientes latinoamericanos.Objetivos: describir las características de los pacientes con trasplante hepático por HAI y evaluar aquellas asociadas con su recurrencia durante el postrasplante.Métodos: cohorte histórica, incluyó pacientes con HAI diagnosticada a partir de los 16 años y que fueron llevados a trasplante hepático en un hospital universitario de Medellín, Colombia, entre enero de 2010 y septiembre de 2017. La recolección de la información se realizó a partir de los registros de historia clínica.Resultados: se incluyeron 25 pacientes. Se diagnosticó recurrencia en el 24%. La mediana de seguimiento fue de 59,5 meses y de recurrencia 32,5 meses (rango 11-123 meses). El 100% del grupo de recurrencia era de sexo femenino y ninguna de estas se trasplantó por insuficiencia hepática aguda. No hubo diferencias en las características pretrasplante y de tratamiento, aunque se encontró una mayor actividad inflamatoria bioquímica e histológica pretrasplante en el grupo de recurrencia. Del grupo con recurrencia, el 100% recibió glucocorticoides a largo plazo y el 33,3% tuvo pérdida del injerto relacionada con la recurrencia, por lo que requirieron retrasplante (p = 0,008).Conclusión: La recurrencia de HAI postrasplante hepático en nuestros pacientes es similar a la reportada mundialmente, es una causa de disfunción del injerto para tener en cuenta especialmente después del primer año postrasplante, predomina en mujeres. El 33,3% de los pacientes requiere retrasplante hepático por disfunción del injerto.

El consumo de alcohol es un conocido factor de riesgo para muerte prematura, morbilidad y discapacidad a nivel mundial. Los registros de la mortalidad que se asocian con el consumo de alcohol están fraccionados. El objetivo de este estudio fue escribir la mortalidad relacionada con la ingesta de alcohol en pacientes con cirrosis atendidos en un hospital universitario de la ciudad de Medellín.Materiales y métodos: se incluyeron 163 pacientes con diagnóstico de cirrosis, evaluados en la consulta externa de hepatología de un hospital de referencia en la ciudad de Medellín con 277 camas y seguimiento hasta el 2016. Se midieron variables sociodemográficas, paraclínicas y clínicas. Se consideró el consumo de alcohol al inicio del seguimiento. Se describió la supervivencia y las complicaciones asociadas con la cirrosis según el estado de consumidores vs. no consumidores de alcohol. Resultados: se siguieron 163 pacientes hasta diciembre del 2016, encontrando una mortalidad en el 51% en consumidores de alcohol vs. 39% en no consumidores (P = 0,19). Las complicaciones de la cirrosis en consumidores de alcohol fueron ascitis en 68% vs. 43% (P = 0,01) en el grupo sin consumo de alcohol, encefalopatía 40,6% vs. 13,5% (P = 0,00) y carcinoma hepatocelular (HCC) en 29% vs. 17% (P = 0,08). En el análisis por subgrupos, los pacientes con hepatitis C con consumo de alcohol tuvieron una mortalidad más alta comparado con los pacientes que no consumieron alcohol (OR 33, IC 95%: 1,06 a 1023).Conclusiones: a pesar que el consumo de alcohol no se relaciona con aumento de la mortalidad en pacientes con cirrosis en este estudio, sí se observa incremento de esta en ciertas poblaciones, como en el subgrupo de pacientes con hepatitis C.
