Acoustic horn design for joining metallic wire with flat metallic sheet by ultrasonic vibrations
Authors: J Pradeep Kumar , K Prakasan
Published: November 2018

Ultrasonic Metal Welding is a green manufacturing technique and one of the most advanced solid state welding processes in which similar or dissimilar metallic components are joined by the application of high frequency vibrations (> 20 kHz) and pressure. Ultrasonic metal welding is accompanied by slip and plastic deformation so that the base metals being welded will not melt and in turn forms a homogenous coalescence of two metals at the joining area so that the joint retains the parent metal properties. The major problem faced by the industries using ultrasonic metal welding process is the poor weld quality and weld strength. The design of acoustic horn or sonotrode plays a dominant role in producing quality welds. The primary function of sonotrode is to vibrate at a level required for welding and also to transmit the vibration energy to the point where welding of metals takes place. For producing quality welds, the vibration energy is to be transmitted to the weld interface without much loss. Therefore, there is a need for accurate design of sonotrodes in ultrasonic metal welding process. This work focuses on designing a stepped sonotrode used for joining metallic wire with metallic sheet based on significant design parameters such as amplitude gain and von Mises stress factor using modal and harmonic analysis. Experimental trials are conducted using the stepped sonotrodes and the effectiveness of the designed sonotrodes is evaluated based on improvement of strength of the joint in tension.

Authors: Santiago-Rivera José Armando
Published: November 2018

En el presente artículo se analizan otras explicaciones que se han dado sobre la situación geográfica del actual momento histórico. Se asume que en el acto de enseñar geografía se ha enfatizado lo descriptivo sin procurar la comprensión crítica de la complejidad contemporánea. Así, para abordar esta problemática se determinó, metodológicamente, interrogar a diez (10) personas que se encontraran cursando estudios en docencia en geografía, para diagnosticar sus percepciones sobre esta situación. Las respuestas revelaron sus inquietudes sobre el complicado acento aldeano globalizado, la debilidad de la educación para entender la situación geográfica, y la necesidad de promover la explicación crítica como opción para educar en valores a los ciudadanos. Finalmente, en la conclusión se señala que la enseñanza de la geografía debe ser coherente con la época y que se debe educar en valores de compromiso y responsabilidad social ante un momento histórico complicado y difícil para la sociedad contemporánea.

Authors: Mores Guilherme José , Bobrowski Rogerio
Published: November 2018

Os objetivos da presente pesquisa foram avaliar a contribuição de poleiros artificiais na chuva de sementes em área degradada no campus da Universidade Estadual do Centro-Oeste (Unicentro), em Irati (PR), e o efeito da distância da floresta e da sazonalidade na dispersão das sementes. Para tal foram instaladas dez esteiras de coleta no interior de remanescente florestal e 80 em área degradada adjacente à floresta, a diferentes distâncias da floresta, sendo a metade das esteiras com poleiros de 4 m de altura. Constatou-se diferença significativa em relação a biomassa, número, peso e diversidade de sementes entre as esteiras com e sem poleiro. O fator distância do poleiro à floresta mostrou-se significativamente diferente, com maior número de sementes na distância de 5 m. Quanto à comparação dos meses de coleta, houve diferença expressiva para os tratamentos com poleiro apenas para a variável biomassa. O número de sementes foi maior nos meses de outubro, novembro e fevereiro, enquanto em novembro e dezembro constatou-se maior diversidade de sementes. A síndrome de dispersão zoocórica e a diversidade de sementes foram maiores nas esteiras com poleiros. Os poleiros artificiais mostraram-se úteis para aumentar a diversidade de espécies e a quantidade de material depositado, o quepode auxiliar na recuperação de áreas degradadas.

Authors: Júnior Ivam Freire da Silva , Stüermer Vanessa Müller , Hartwig Andreia Drawanz , Scharsdosim Lisandrea Rocha , Azevedo Marina Sousa
Published: November 2018

Introduction: People with special health care needs (SHCN) have a higher risk of contracting certain oral diseases, such as dental cavities and gingivitis, and a limited use of dental care services can significantly affect these risks. Objective: To assess the use of dental care services and related factors in students with SHCN. Materials and methods: This cross-sectional study included subjects from a rehabilitation and education center. The guardians were asked aboutwhether the students already made a dental appointment and about the last time they had visited their dentist. The students were examinedfor dental cavities. Fisher’s exact test for the association between the outcome and independent variables was employed. Results: The study sample comprised 51 guardians. Forty-seven students had already visited their dentist at least once, and 68% underwent a dental exam within the past year. A recent use of dental service (1 year or less) was more prevalent among female subjects, which did not present a history of dental cavities and about whose caregiversalready had received oral health information. Conclusion: Most of the participants already had visited their dentist and regularly usedental services. Caregivers should be encouraged to make regular dentist appointments for SHCN subjects, especially for those who already have oral problems, are male, and whose families have never received oral health information.
Use of Hemoglobin for Delivering Exogenous Carbon Monoxide in Medicinal Applications
Authors: Taguchi Kazuaki , Maruyama Toru , Otagiri Masaki
Published: November 2018

Carbon Monoxide (CO), at low concentrations, can have a variety of positive effects on
the body including anti-apoptosis, anti-inflammatory, anti-oxidative and anti-proliferative effects.
Although CO has great potential for use as a potent medical bioactive gas, for it to exist in the body
in stable form, it must be associated with a carrier. Hemoglobin (Hb) represents a promising material
for use as a CO carrier because most of the total CO in the body is stored associated with Hb in red
blood cells (RBC). Attempts have been made to develop an Hb-based CO carrying system using
RBC and Hb-based artificial oxygen carriers. Some of these have been reported to be safe and to
have therapeutic value as a CO donor in preclinical and clinical studies. In the present review, we
overview the potential of RBC and Hb-based artificial oxygen carriers as CO carriers based on the
currently available literature evidence for their use in pharmaceutical therapy against intractable disorders.

Published: November 2018

The human skin undergoes the complex process of aging which is prompted by the interplay
of intrinsic mechanisms and extrinsic influences. Aging is unavoidable but can be somewhat delayed.
Numerous approaches have been developed to slow down facial skin aging process as it is of interest to
stake holders in the beauty and fashion world as well as to plastic surgeons. Adipose-derived stem cell
[ADSC] and mesenchymal stem cell [MSC] as potential anti-aging agents to some extent have provided
a promising and effective alternative in managing skin and facial skin aging. Furthermore, bone
marrow-derived mesenchymal stem cells [BMMSC] have exhibited similar ability to rejuvenate aged
skin. This review is aimed at giving a comprehensive account of the application of stem cells especially
ADSCs and MSCs to reduce or slow down the rate of facial skin aging process.

:

As an important global disease, cutaneous leishmaniasis is associated with
complications such as secondary infections and atrophic scars. The first line treatment with
antimonials is expensive and reported to have serious side effects and enhance resistance
development. The main objective of this study was to evaluate the effect of Cinnarizine on
standard strains of Leishmania major because of paucity of information on this subject.

Methods:

In this experimental study, four concentrations of the drug (5, 10, 15 and 20 μg/ml)
were added to Leishmania major cultures at 24, 48 and 72 hours intervals. MTT assays were
performed to determine parasite viability and drug toxicity. Leishmania major promastigotes were
augmented to the in vitro cultured macrophages (J774 cells) and then incubated for 72 hours. Half
maximal inhibitory concentration (IC50) was ascertained by counting parasites. The inhibitory
effect of the drug was compared with that of Glucantime. Flow-cytometry was performed to
investigate apoptosis. Each test was repeated thrice.

Results:

The IC50 values of Cinnarizine after 72 hours were calculated to be 34.76 μg/ml and
23.73 μg/ml for promastigotes and amastigotes, respectively. The results of MTT assays showed
48 % promastigote viability after 72 hour-exposure to Cinnarizine at 20 μg/ml concentration.
Programmed cell death in promastigote- and amastigote-infected macrophages was quantified to
be 13.66 % and 98.7 %, respectively. Flow- cytometry analysis indicated that Cinnarizine induced
early and late apoptosis in parasites. All treatments produced results which differed significantly
from control group (P<0.05).

Conclusion:

Cinnarizine showed low toxicity with anti-leishmanial and apoptosis effects on both
promastigote and intracellular amastigote forms. Therefore, we may suggest further assessment on
animal models of this drug as candidates for cutaneous leishmaniasis therapy.

Authors: Pathak Dr. Mridula , Mhatre Dr. Ashish
Published: November 2018

Madhumeha ‘Richman's disease’, since Vedic period, is familiar to mankind. Madhumeha is a disease in which Mutra (urine) of the patient attains similar property like those of Madhu (Honey). It is also explained that, when the other Prameha are left untreated, this lead to the condition called Madhumeha. So Madhumeha can also be considered as an advanced condition or stage of Prameha. Diabetes Mellitus is a chronic disorder of carbohydrate metabolism, marked by hyperglycemia and glycosuria and resulting from inadequate production or use of insulin. In present study the reassessment of Madhutailika Basti has been done to understand its efficacy in Diabetes mellitus. Madhutailika Basti, contains Madhu, Erandamool Kwatha, Til Taila, Shatapushpa Kalka, Saindhava Lavana. The improvement was calculated by subjective parameters like Prabhutavil Mutrata (polyurea), Kshudha Vruddhi (polyphasia), Pippasa Vruddhi (polydipsia), Dourbalya (general weaknesss), Paridaha (burning sensation), Kandu (itching), Bhrama (vertigo), Anidra (insomnia), Nakta Mutra Pravrutti (urination during night), Hast Pada Chimchimaya (tingling) to score clinical outcome. Here statistical analysis was done with the help of Mann-Whitney test which shows some promising results, i.e. p less than 0.0001. These results show a window of opportunity to treat Madhumeha with Ayurvedic perspective to provide better life to the patients

Authors: C. Dr. Suchithra , BV. Dr. Rekha
Published: November 2018

Background: Menarche and menopause are the two major components of women’s reproductive life. Perimenopause is a transition stage from reproductive phase to non reproductive phase, which begins several years before the actual menopause. It demands priority in the Indian scenario due to increase in life expectancy and growing population of menopausal women. During this phase there is imbalance in the hormonal levels which causes both physical and emotional symptoms. Yoga, a potential alternative to hormone therapy, is currently being assessed for its therapeutic value in decreasing stress and other symptoms associated with Perimenopause. Hence this study was undertaken to see the effect of selected yoga techniques in reducing the physical and psychological symptoms in Perimenopause women. Materials and Methods: It was an Open Randomized Comparitive Clinical Trial of 2 groups was adopted with pre-test and post-test design. 25 subjects in each group were selected using the inclusion and diagnostic criteria with selected Yogasanas and Pranayama and selected Pranayama respectively. The subjects were taught with selected Yoga techniques for a week and given printed protocol. They were asked to continue the therapy for 60 days. The criteria assessed were irregular menstruation, hot flushes, night sweats, palpitation, fatigue, weakness, depression, insomnia, irritability, mood swing and anxiety on 0th, 30th, 60th and 90th day. Results: Selected Yogasanas and Pranayama has given statistically significant results in reducing all the physiological and psychological symptoms in Perimenopausal women whereas Selected Pranayama showed statistical significance in symptoms like Hot Flushes, Night Sweats, Palpitation, Fatigue, weakness, Insomnia and Irritability and showed no statistical significance in Irregular Menstruation, Depression and Anxiety. Conclusion: The symptoms were reduced statistically in Selected Yogasanas and Pranayama when compared to Selected Pranayama Group.

Visceral obesity syndrome also known as metabolic syndrome X is the bunch of medical conditions characterised by hypertension, hyperglycaemia, dyslipidemia and atherosclerotic cardiovascular disease affecting, nearly 240 million people worldwide. In India nearly 10000 people were affected per year and overall it goes on escalating steadily due to amplified adulterated human behaviours. There is a need of exigency at this juncture by knowing its complex pathology to condense human anguish and financial load. Siddha system of medicine primarily describes as it may arise due to provocation of the humours of the body. When our moral code of demeanour is deprived including intemperance and deficit physical activity, there is a flawed tissue metabolism leading to metabolic syndrome (MS). Classical books of Siddha were used for literary survey and databases were also analysed with the prime terminology “Metabolic syndrome” for this systemic review. The speculative backdrop, broad set of strategy in aetiology, pathogenesis and management of MS are discussed at extent through Siddha system, in the paper which would be creditable in managing in an effectual and gainful approach.

Published: November 2018

Pregnant women commonly develop increased vaginal discharge, which in many instances is not pathological. Pregnancy is associated with specific anatomical, physiological and immunological changes that can predispose to infection and also alter the response to the disease process. Infections in pregnancy demands prompt adequate and careful management. Vulvovaginitis during pregnancy may be considered under the umbrella of Upapluta Yonivyapad. Pregnant women are more prone to vulvovaginitis which is a great challenge for obstetricians today. In Ayurveda, Upapluta Yonivyapad described by Acharaya Charaka, Sharangadhara and both Vagbhata can be compared to vulvovaginitis during pregnancy. Here Panchawalkala Kwatha Prakshalna followed by Jatyadi Taila Pichu externally and Tab Leukol internally has been used to correct Garbhini Upapluta.

It takes into account the influence of eddy currents in the motor frame, armature current ripples and the catenary voltage increase during recuperative braking.

Electromagnetic processes in the electric train power circuit are investigated. Analysis of the obtained oscillograms shows the change in the armature current and the catenary voltage within the specified limits in the braking mode. Recuperative current regulator is tuned to an aperiodic transient with a time equal to 0.015 s.

The paper shows possibility of the monitoring system to regulate the armature current in the recuperative mode together with the automatic braking control system in case of increasing the catenary voltage. When the voltage fails, the monitoring system is not able to limit the increasing braking current, its reduction is effected by the magnetic flux of the traction motors.

Adjusting characteristic and the technical effect from the implementation of the monitoring system are calculated. The possibility of reducing the electric power consumption by 4.62 % is shown.

Published: November 2018

In the diverse genus Psychoda, a great number of species are described based only on one sex, mainly for the difficulties of sexual association in this taxon. Immatures of coprophagous moth flies were captured on a sample of cow dung left exposed during five days at Reserva Ducke (Manaus, Brazil), in the Brazilian Amazon. The presence of Psychodidae larvae was confirmed with a stereomicroscope and the material was kept resting at room temperature until the emergence of adults. Male and females of Psychoda serraorobonensis Bravo, Cordeiro & Chagas, 2006 were obtained and associated by the morphology of the immatures and adults. The male of P. serraorobonensis is herein described and illustrated and the distribution of this species in Brasil is updated. This is the first data about the feeding habits of this species.

Published: November 2018

Los insectos son considerados los principales portadores de polen del aguacate Persea americana cv. Hass. Con el objetivo de determinar el efecto de su exclusión en la fructificación del cultivo, se planteó esta investigación en dos plantaciones ubicadas en Popayán (Cauca, Colombia). En cada finca se marcaron 10 árboles y en cada árbol 20 inflorescencias. Se evaluaron tres tratamientos: (a) inflorescencias expuestas a la actividad de los insectos (control), (b) cubrimiento de inflorescencias con bolsas de tela, y (c) aplicación de insecticida una sola vez y cubrimiento de inflorescencias con bolsas de tela. El número de frutos cuajados (fructificación) difirió significativamente entre tratamientos y fincas, en el tratamiento con inflorescencias expuestas hubo un cuajado de fruto 7 veces más alto respecto a los tratamientos con inflorescencias cubiertas e inflorescencias cubiertas + insecticida, los cuales no presentaron diferencias estadísticas significativas entre ellos. Se obtienen entre 12- 21 frutos/inflorescencia cuando se permite el acceso de los insectos a las flores, comparado con 2-3 frutos/inflorescencia cuando se excluyen. Se concluye que en la polinización del cultivo de P. americana cv. Hass interviene el viento, sin embargo, los insectos tienen un rol clave como portadores de polen.

Published: November 2018

Anfibios y reptiles son grupos de vertebrados que históricamente ha sido utilizado por comunidades rurales. En México, la multiculturalidad del país está estrechamente relacionada con la diversidad biológica con la que coexiste. El uso del Índice de Importancia Cultural (IIC) permite cuantificar el valor de las especies con diversos usos y puede ser de utilidad para enfocar estrategias de conservación, tomando en cuenta el valor cultural de las especies. El objetivo del estudio fue identificar los usos y generar un IIC de la herpetofauna, mediante un meta-análisis bibliométrico de publicaciones sobre el uso de anfibios y reptiles mexicanos. Se registraron 103 reptiles y 32 anfibios que tienen al menos un uso, el cual varió dependiendo del taxón (reptiles o anfibios, respectivamente): alimenticio (47, 10), mascota (20, 6), comercial (20, 2), ornamental (25, 1), artesanal (32, 9), mágico-religioso (32, 10), medicinal (57, 19), caza deportiva (2, 2), control de daños (48, 2), benéfico (10, 4), otros (3, 3). Rhinella marina (27.13) y Crocodylus moreletii (15.42) fueron las especies con mayor IIC. De las especies registradas, el 61 % y 31 % de reptiles y anfibios, respectivamente, están en alguna categoría de riesgo. Es necesario establecer estrategias de conservación por medio de manejo y programas educativos que promuevan alternativas de uso sustentable de los recursos, así como la conservación de espacios naturales donde las especies habitan.

Published: November 2018

la mixteca poblana los mamíferos silvestres son un grupo sujeto a constante presión antrópica. El tipo de investigaciones que se han hecho en la zona se enfocan a especies con importancia cinegética, esto conlleva a un sesgo en la valoración ecológica del resto de especies de mamíferos en la región, además de no tomar en cuenta el conocimiento tradicional y las necesidades de las personas que aprovechan la fauna silvestre. Ante esto, se hace necesario conocer el uso, los saberes locales, actitudes y acciones hacia los mamíferos silvestres que tienen los habitantes, mediante la determinación de su importancia cultural, y la posible inclinación hacia la conservación y el uso sustentable de los mamíferos silvestres en la zona de estudio. El valor de uso más importante en la Mixteca es el de alimento con un 49.2% de mención, seguido del uso medicinal (23.7%), trofeo (13.7%), amuleto (8.2%), decoración (2%), comercio (1.1%) y aprovechamiento cinegético, ritual, vestimenta, taxidermia y mascota (<1%). Las especies con más usos son el venado cola blanca con 9 usos, el tejón con 8, el coyote con 6 y el zorrillo el cual solo tiene 3 diferentes usos, pero con mayor número de menciones que el coyote. Las especies con un mayor índice de importancia cultural (IIC) fueron: venado cola blanca, tejón, coyote, armadillo, zorrillo, zorra gris y leoncillo. En cuanto a la percepción que los habitantes tienen de las 12 especies de interés en el estudio, el coyote y el tlacuache son de desagrado, esto a pesar, de que el coyote culturalmente es importante y de gran utilización. En la mixteca poblana, las especies que no tienen un uso como alimento obtuvieron un IIC y valor de uso bajo; los carnívoros (orden Carnivora) son considerados como perjudiciales y son eliminados para evitar daños en los sistemas productivos. El coyote es de los carnívoros con mayor demanda por los múltiples usos que representa y aunque tiene un IIC alto, la percepción negativa que se tiene por las creencias, mitos y el miedo que infunde en la gente, impiden que sea una especie con prioridad de manejo y conservación por parte de las comunidades estudiadas.

Published: November 2018

In this study water repellent layered glass has been prepared by coating silica (SiO2) combined with a hydrophobic silane compound. SiO2 was extracted from rice hull ash and two silane compounds, namely hexadecyltrimethoxysilane (HDTMS) and trimethylchlorosilane (TMCS) were used. Coating was performed through two deposition techniques, i.e. one step (mono-layer) and layer by layer (LBL, multi-layer). The effect of silane to SiO2 mole ratio, silane type and layer number on the glass characters was evaluated. Characterization included hydrophobicity, transparency, surface roughness and stability of coating. Results showed that increasing the mole ratio of silane to SiO2 and the layer number increased the hydrophobicity of the glass surface. The optimum mole ratio was 5:1 and the significant increase of contact angle occurred at lower mole ratio, but the stability tends to be increased at higher mole ratio. For HDTMS-SiO2 layer, the technique of LBL technique produced a coating with higher hydrophobicity and transparency than single-stage one. The LBL technique produced the highest water contact angle of 103.7° with transmittance of 96%, while for TMCS-SiO2 layer the one stage technique produced hydrophobic layer with higher water contact angle of 108.0° and transparency about 94.52%. The prepared hydrophobic glasses were relatively stable in polar and non-polar solvents, but unstable to ambient conditions.

Published: November 2018

The powder complex of tris(bipyridine)cobalt(II) trifluoromethanesulfonate octahydrate has been synthesized by direct interaction of the corresponding aqueous solutions (and drops of ethanol) of cobalt(II) nitrate, bipyridine, and potassium triflate. The yellow-orange powder produced was filtered off and allowed to dry on an aeration for characterization. AAS measurement showed the content of metal to be 6.06%, corresponding to the theoretical value of 6.06% in [Co(bipy)3](CF3SO3)2.8H2O. The analysis of conductance producing the charge ratio of cation to anion to be 2:1, confirms the formula. The magnetic moment, µeff, of this complex which was to be 4.5-4.9 BM, indicates that the complex is paramagnetic corresponding to the three unpaired electrons with a significantly orbital contribution. UV-Vis spectrum of the complex reveals the first band observed at about 11100 cm–1, which is associated with the spin-allowed transition, 4T1g → 4T2g. A distinct shoulder at only about 16100 cm–1 should be associated with the spin-forbidden transition of 4T1g → 2T2g,2T2g (G). The expected second and third bands which are associated with spin-allowed transitions of 4T1g → 4T1g(P) and 4T1g → 4A2g at higher energy were not well resolved. The infrared spectrum shows absorptions of the functional group of ligand which is influenced by the metal-ligand interaction in this complex. The powder XRD of this complex was refined using Le Bail method of Rietica program and found to be fit as monoclinic symmetry with a space group of C2/c.

Published: November 2018

Older adults’ day-to-day leisure time activities both reflect and stimulate physical, cognitive, and social capacities that contribute to their quality of life. To better understand how leisure activity choices and possible impacts vary across two cultures, this questionnaire-based study compared leisure time use, perceived meaning of life, and psychological distress for 617 older adults in Canada (n=298) and the Republic of Korea (Korea) (n=319). Compared to Koreans, Canadian respondents spent more time overall in leisure activities and devoted a higher percentage of their total leisure time to active, rather than passive, activities. They spent significantly more of their time on cognitively active activities, while Koreans preferred socially and physically active ones and scored significantly higher on both meaning of life and psychological distress. Both groups spent more of their time watching television than on any other single reported activity. Age group, retirement status, health, education, and income varied across the two countries and were significantly associated with aspects of leisure time use for each group. The results identify areas for improvement if Canadian and Korean older adults’ leisure time use is to effectively support their aging well.

Authors: Robles Vásquez Héctor V. , Degante Méndez Luis A. , Ángeles Méndez Eduardo
Published: November 2018

Se aportan evidencias de los avances y retos que afronta el Estado mexicano para garantizar el derecho humano a una educación obligatoria de calidad.El monitoreo realizado se limitó al componente de inclusión social. Se distingue el ámbito nacional y el de las entidades federativas, que se agrupan porsu contexto socioeconómico y escolar. La organización funcional por tipos de servicio o subsistemas en la educación básica y en la media superior, respectivamente, ha devenido en una estratificación social de la educación. Además, es probable que la mayor deuda social del sistema educativo nacional consiste en no garantizar aprendizajes necesarios para importantes proporciones de niños y adolescentes, toda vez que hay avances en la asistencia, permanencia y egreso de la educación básica y, en menor medida, en la educación media superior. Se identifica la necesidad de evaluar la equidad en elcomponente de justicia social del derecho a la educación en México.
Tumour Emboli Causing Multifocal Ischemic Stroke from Intracardiac Malignant Solitary Fibrous Tumour
Authors: Melvin Lindsay J , Sitzer Nicole , Amer Rebecca
Published: November 2018

A 78-year-old woman presented to the emergency department with gait ataxia and diplopia. Her past medical history included the surgical resection of a phyllodes breast tumour 8 years prior, with no known recurrence. A computed tomography (CT) scan of the brain demonstrated multifocal right supratentorial hemispheric subacute infarcts in the frontoparietal, posterior temporal and occipital regions. The patient developed recurrent generalized seizures in hospital. Transesophageal echocardiogram demonstrated a large 2.7 × 1.8 × 0.8 cm mobile echogenic mass attached to the left posterior atrial wall. CT angiogram of the chest revealed the left atrial mass as well as a mass encasing the right bronchus intermedius. The patient opted for comfort care and passed away in hospital. Autopsy revealed the tumour to be a primary cardiac solitary fibrous tumour. We present a case of multifocal ischemic stroke and seizures secondary to tumor emboli originating from intracardiac solitary fibrous tumour.

Desenvolver, no âmbito da Análise do Discurso (escola francesa), perspectivas voltadas ao estudo da imagem (fílmica, fotográfica, artística, gráfica, publicitária, etc) em sua materialidade, no caso, o não verbal. Discutir a questão relativa à materialidade da linguagem (verbal e não-verbal), visando à formulação de um campo novo de descrição e análise do não-verbal, aquele que não vai pressupor, em primeira instância, o repasse do não-verbal pelo verbal. Descartando-se, assim, pressupostos outros como os oriundos da Lingüistica e da Semiologia no estudo da imagem, formula-se o conceito de policromia, base de análise da imagem.

Nota introdutória de Dênis de Moraes:Em 13 de janeiro de 1999, Robert W. McChesney gentilmente me autorizou a publicar, na nossa revista eletrônica Ciberlegenda, o importante artigo a seguir, baseado em questões abordadas em seu livro Corporate media and the threat to democracy (Seven Stories Press, 1997). PhD e professor da School of Journalism and Mass Communication da University of Wisconsin-Madison, nos Estados Unidos, é um dos mais categorizados pesquisadores sobre as mídias globais. Insere-se na tradição intelectual de Noam Chomsky e de Herbert I.

Reality shows: el espectáculo de la intimidad en la televisión argentina
Authors: Caminos Alfredo , Aranguren Mariana
Published: November 2018

Los "reality shows" se han instalado finalmente en la programación televisiva argentina, ahora ya son motivos de análisis de todos los programas de televisión y radio y de artículos periodísticos en la prensa gráfica. Incluso buceando en las librerías pueden verse en diferentes publicaciones opiniones y análisis de otros países por donde ya han pasado y siguen vigentes. Los debates giran en torno a la forma de representación de esa realidad, la ficción presente en el producto terminado y cuanto de espectáculo y juego hay en los mismos. La propuesta de esta comunicación es encontrar otra mirada que posibilite una nueva denominación acorde con la propuesta estética, y observar como la sociedad consumidora de televisión atiende este tipo de obras audiovisuales.Para ello se intentará reflejar algunas particularidades, parciales por cierto, como aproximación a estos espectáculos de la realidad, estos "shows" de la intimidad.

(Re)settlement, Displacement, and Family Separation: Contributors to Health Inequality in Nunavut
Authors: Healey Gwen
Published: November 2018

A series of relocation events in the Canadian Arctic in the mid-twentieth century contributed to widespread disruption of Inuit families. The objectives of this article are to: 1) provide a synthesis of the literature and oral histories about Inuit and Western academic perspectives on family attachments; 2) share findings from a recent study on perspectives of family relationships, which interviewed Inuit parents—many of whom were children at the time the relocation events in the 1950s and 1960s; and 3) discuss the role of severed family attachments on health inequality in Nunavut. The research was conducted within an Indigenous knowledge framework, specifically, the Piliriqatigiinniq Partnership Community Health Research Model (Healey & Tagak Sr., 2014). Data were collected in face-to-face interviews with twenty Inuit parents in three Nunavut communities. An analytical approach building on the concept of Iqqaumaqatigiinniq (all knowing coming into one), “immersion and crystallization,” was used to identify story elements in the data. Parents in the study identified the experience of forced relocation and/or attendance at residential school as traumatic events for families. These events broke the chain of Inuit knowledge transmission, which participants blamed for health inequalities observed in northern communities today. Participants who did not experience relocation attributed their confidence and ability to communicate health knowledge to the bonds they had with their children. Reclaiming and revitalizing Inuit attachment perspectives is part of the path to overcoming the trauma that Canadian Inuit families have experienced, and which is a contributor to health inequality in the region. Focusing on wellness-promoting pathways in our communities can, in turn, help reduce the health inequality gap in the North.
