Effects of different electrodes used in bone-guided extracochlear implants on electrical stimulation of auditory nerves in guinea pigs
Authors: Liu Chien-Hao , Lu Yung-Shan , Chen Po-Chun , Lee Chia-Fone
Published: January 2021

Objective:

Conventional cochlear implants provide patients who are deaf with hearing via electrical intracochlear stimulations. Stimulation electrodes are inserted into the cochlea through a cochleostomy or round window membrane (RWM) approach. However, these methods might induce cochlear ossificans and loss of residual hearing by damaging inner ear structures. To avoid an invasive electrode insertion, we developed a novel bone-guided extracochlear implant that stimulated the auditory nerves between the cochlear bones and the RWM to prevent cochlea damage. Power consumption plays an important role in wireless implantable electronic devices. Therefore, we aimed to investigate the effects of different electrodes on the stimulating threshold currents of the auditory nerve and the power consumption of bone-guided extracochlear implants using a commercial stimulator.

Materials and Methods:

Inert aurum (Au) electrodes were compared with biocompatible platinum (Pt) and iridium oxide (IrOx) electrodes in practical implantable applications. IrOx electrodes were used for their high-charge storage capacity, low impedance, and biocompatibility. The electrodes were fabricated via sputtering and were experimentally characterized with cyclic voltammetry and then examined using in vivo tests.

Results:

Based on electrical auditory brainstem responses, IrOx electrodes yielded lower acoustic nerve-stimulating threshold currents (132 μA) compared with Au electrodes (204 μA). IrOx electrodes also had a lower acoustic nerve stimulating threshold current (132 μA) compared with Pt electrodes (168 μA).

Conclusion:

As expected, IrOx electrodes were beneficial in the development of multielectrode bone-guided extracochlear implants, with the lowest acoustic nerve-stimulating threshold and current consumptions compared with Au and Pt electrodes.

Infection with Leptospira spp. is common in Réunion, a tropical island in the Indian Ocean. However, respiratory coinfections between strains of Leptospira spp. and other microorganisms are rarely described. Here, we describe the first reported case of coinfection between Leptospira spp. and Chlamydia pneumoniae, responsible for refractory acute respiratory distress syndrome requiring extracorporeal membrane oxygenation with a favorable outcome. In a case of leptospirosis with severe respiratory illness, testing for respiratory coinfection, especially with atypical pathogens, could explain the seriousness of the clinical condition and lead to specific treatment.

El trabajo doméstico y su protección social, en la visión de Venezuela
Authors: Tropiano Sanoja Ydangely , Noguera González Atilio Alberto
Published: January 2021

El artículo 207 de la Ley Orgánica del Trabajo, los Trabajadores y las Trabajadoras, los denomina trabajadores de hogar, quienes realizan labores en casa de habitación o a una persona determinada, para su servicio personal o de su familia, estando los chóferes particulares, camareros, cocineros, jardineros, niñeras, lavanderos, planchadoras y otros oficios de igual índole. Cabe resaltar, que en Venezuela el régimen de estos trabajadores en principio estaba desarrollado en la legislación laboral derogada (1997), sin embargo con la legislación laboral vigente (2012), las características y demás disposiciones señaladas en la derogada legislación fueron suprimidas, al establecerse que las normas que regirán las relaciones laborales de estos trabajadores serán contempladas en una ley especial-normativa que aún no ha sido promulgada- lo que ha conllevando que su régimen ha sido desarrollado por doctrina y sentencias del Tribunal Supremo de Justicia, donde además tampoco ha ratificado, a diferencia de otros países, el convenio 189 (2011) de la OIT. Por ello, que el objetivo del artículo es presentar el escenario de la protección social del trabajo doméstico en Venezuela, labor de predominio precario, desempeñada generalmente por mujeres migrantes y con una significativa exposición a riesgos laborales.

Published: January 2021

Sanayi toplumundan bilgi toplumuna geçiş sürecinde örgütlerin varlıklarını sürdürebilmeleri için birçok farklı kaynağa ihtiyaç duyduğu bilinmektedir. Sürecin başlangıcında çalışanların görevlerini belirtmek için sözlü veya yazılı bir süreç olarak benimsenen iletişim; daha sonra bilgi toplumunda vazgeçilmez bir kavram haline gelmiştir. Sürekli ve hızlı değişen günümüz koşulları, hem işletmeleri bu duruma uymaya ve sürekli yenilik yapmaya zorlamakta, hem de yoğun bir rekabetle karşı karşıya bırakmaktadır. Böylesi zorlu bir süreçte, işletmelerin değişime ayak uydurması ve rekabet üstünlüğü sağlaması için en önemli kaynaklarından birisi de insan kaynağıdır. Burada temel hedef yöneticilerin çalışanlardan daha etkin sonuç almaları, ikinci hedef ise çalışan memnuniyet düzeyinin yükseltilmesidir. Bu doğrultuda örgütsel iletişimin önemi göz ardı edilmemelidir. Örgütsel iletişim örgüt içinde ve örgütün çevresi ile arasındaki her türlü bilgi ve fikir alışverişi olarak tanımlanmaktadır. Sosyal zeka ise, bireyin diğer bireyler ile ilişkilerinde, ilişkiyi anlamlandırma, duygusal bağ kurma, işbirliği yapabilme yeteneği ve sosyal etkileşim becerisi olarak ifade edilmektedir. Bu çalışmanın amacı çalışanların algılanan soysal zekalarının örgütsel iletişimlerine etkisinin basit ve çoklu doğrusal regresyon analizi ile belirlenmesidir. Bu çalışmaya konu olan değişkenler, temelinde etkileşimin yer aldığı sosyal zekâ ve örgütsel iletişimdir. Araştırma 2019 yılı Kasım-Aralık aylarında kolayda örneklem yöntemi ile ulaşılan 385 çalışan üzerinde uygulanmıştır. Anketlerden elde edilen veriler SPSS istatistik programı çıktıları ile yorumlanmış ve hipotezler test edilmiştir. Araştırma yöntemi olarak basit ve çoklu regresyon analizi yapılmıştır. Araştırmanın sonucunda çalışanların algılanan sosyal zekâlarının örgütsel iletişime etkisinin çok düşük olduğu tespit edilmiştir. Gelecekteki çalışmalar için yorum ve önerilere de yer verilmekte ve çalışmanın hem literatüre hem de sektörel alana katkı sağlayacağı düşünülmektedir.

Published: January 2021

Peran perempuan Indonesia saat ini dapat digambarkan sebagai manusia yang hidup dalam situasi dramatis. Disatu sisi perempuan Indonesia dituntut untuk berperan dalam semua sektor, disisi lain muncul tuntutan agar perempuan Indonesia tidak melupakan kodrat sebagai perempuan. Situasi dilematis yang dihadapi oleh para perempuan, dialami oleh perempuan Indonesia yang berkarir. Perempuan karir merasa terpanggil untuk mendarmabaktikan bakat dan keahlian bagi perkembangan bangsa dan negara. Disamping itu, perempuan sering di hantui oleh opini yang ada dalam masyarakat bahwa perempuan harus mengabdi pada keluarga.  Dalam pandangan siyasah syar’iyyah tentang keterwakilan perempuan dalam partai politik dilihat dari kedudukan perempuan fiqh siyasah merupakan agenda tersendiri dan penting untuk dilihat. Persoalannya tidak sekedar mempertanyakan kembali boleh dan tidaknya perempuan menjadi imam (pemimpin), tetapi bagaimana konsepsi fiqh dalam memandang peran politik perempuan secara umum. Secara garis besar, dalam membicarakan keberadaan hak-hak kaum perempuan dalam berpolitik terdapat pendapat liberal-progresif yang membolehkan perempuan berpolitik dan secara konstektual dapat disimpulkan bahwa kaum perempuan juga berhak menjadi pemimpin sebagaimana kaum laki-laki.  Kebijakan pemerintah tentang kuota perempuan dalam legislatif dilihat dari keterlibatan peran perempuan dalam ranah politik dan pemerintahan merupakan suatu anugerah bagi keberlanjutan suatu negara. Maka dapat dipastikan bahwasannya perempuan memiliki andil yang sanagt luar biasa dalam mengatur kehidupan berbangsa dan bernegara.

Authors: L Radhika Rani , lingam S. Chandra , T Anjaneyulu , K Satyanarayana
Published: January 2021

Congenital Heart Defects (CHD) are the critical heart disorders that can be observed at the birth stage of the infants. These are classified mainly into two, Cyanotic and Acyanotic. The present paper concentrates on the Acyanotic heart disorders. Acyanotic heart disorder cannot be observed on external checkup, whereas bluish skin is the indication for the infant affected with Cyanotic disorder. Acyanotic heart disorder can only be diagnosed using chest X-Ray, ECG, Echocardiogram, Cardiac Catheterization and MRI of the Heart. The present work aims at estimating the fundamental frequency (pitch) and the vocal tract resonant frequencies (formants) from the cry signal of the infants. The pitch frequency and formant frequencies are estimated using frequency domain (Cepstrum) and Linear Prediction Code (LPC) methods. The results show that the fundamental frequency of the cry signal was between 600Hz-800Hz for the infants with Acyanotic heart disorders. This fundamental frequency helps in identifying Acyanotic heart disorders at an early stage.

Dual motor drives designs are attractive for high power application because of their mechanical simplicity, traction and regenerative braking control on low friction surfaces. However, such configurations normally require two power inverters with coordinated control. The high cost and large size of packaging needs of the inverters make such dual inverter, dual motor drive configurations are economically less competitive. Therefore, the need for dual motor drives fed by single inverter rising consequently to reduce sizes and costs with respect to the single motor drives, either in industrial or in traction application. This paper aims to investigate the behavior of dual motor drives fed by single inverter using averaging technique MATLAB/Simulink has been chosen as the simulation tools.

Published: January 2021

The present work is devoted to evaluating seven cubic equations of state (EOS) in predicting gas and liquid phase volumetric properties of nine ozone-safe refrigerants both in super and sub-critical regions. The evaluations, in sub-critical region, show that TWU and PR EOS are capable of predicting PVT properties of refrigerants R32 within 2%, R22, R134a, R152a and R143a within 1% and R123, R124, R125, and y TWU and PR EOS's, from literature data are 0.5% for R22, R32, R152a, R143a, and R125, 1% for R123, R134a, and R141b, and 2% for R124. Moreover, SRK EOS predicts PVT properties of R22, R125, and R123 to within aforementioned errors. The remaining EOS's predicts volumetric properties of this class of fluids with higher errors than those above mentioned which are at most 8%.In general, the results are in favor of the preference of TWU and PR EOS over other remaining EOS's in predicting densities of all mentioned refrigerants in both super and sub critical regions. Typically, this refrigerant is known to offer advantages such as ozone depleting potential equal to zero, Global warming potential equal to 140, and no toxic.

Authors: KHANDAI SURESH CHANDRA , K ASHWIN KUMAR , PARAMMASIVAM K.M.
Published: January 2021

The present work deals with the computational study of the single expansion ramp nozzle (SERN) flows for the supersonic regime. Theoretical calculations are carried out for different geometries with certain assumptions. Based on the initial calculation and with the help of Method of Characteristics, nozzle configuration with similar axisymmetric convergent portion and distinct non-axisymmetric divergent portions are drafted. Commercial CFD software ANSYS 12 with Navier Stokes code is used for the computational studies. The study begins with a simple upper flat ramp at different angles with a very small lower cowl at fixed angles. The divergent section of a conventional three-dimensional nozzle is used as the upper ramp of the SERN. The study includes the variation of the ramp at different angles ranging from 16 deg. to 24 deg. with 2 deg. intervals, the cowl angle ranging from 0 deg. to 6 deg. with 2 deg. intervals and the length of the cowl varying from 0.2, 0.4, 0.6, 0.8 and 1.0 times the length of the ramp. The performance parameters like Thrust, Normal force and Mach Variation for these different contours are analyzed and compared. The various parameters used are nozzle length, cowl length, cowl angle, ramp-angle, and ramp length. The shape of the SERN is optimized for the design parameters. The grid sensitivity computational analysis is also performed before finalizing the grid for study.

Should virgin coconut oil be used in the adjunctive treatment of COVID-19?
Authors: Tan-Lim Carol Stephanie C. , Martinez Corinna Victoria
Published: January 2021

KEY FINDINGS

There is currently no evidence to support the use of virgin coconut oil in the adjunctive treatment of COVID-19.

• Virgin coconut oil is naturally extracted from fresh coconut kernel and is rich in medium chain triglycerides, with lauric acid as the predominant fatty acid.• Virgin coconut oil is currently explored as an adjunctive treatment for patients with COVID-19 due to its antiviral and immunomodulatory properties.• In vitro studies show that lauric acid or its derivative exert inhibitory activities against viruses with similar structure to coronavirus (enveloped ssRNA virus) such as Junin virus, vesicular stomatitis virus, human immunodeficiency virus type 1 (HIV-1), and Semliki Forest virus.• Animal studies demonstrate antiviral activity of monolaurin, the pharmacologically active metabolite of lauric acid, on avian influenza virus and Simean immunodeficiency virus, which are both enveloped ssRNA viruses.• Clinical trials among patients with HIV report that virgin coconut oil can increase CD4+ T lymphocyte counts and reduce viral load.• In vitro and animal studies demonstrate anti-inflammatory properties of virgin coconut oil.• At present, there are no studies that investigate the effectiveness of virgin coconut oil in the adjunctive treatment of COVID-19 infection.• There is currently one ongoing clinical trial in the Philippines evaluating the use of virgin coconut oil in the adjunctive treatment of COVID-19.• Nausea, vomiting, mild diarrhea, and abdominal pain have been reported, but no serious adverse events have been identified with the use of virgin coconut oil.• To date, there are no guidelines that mention virgin coconut oil as an option for the adjunctive treatment of COVID-19.
Is high-flow nasal cannula oxygenation more effective than noninvasive ventilation or conventional oxygen therapy in treating acute hypoxemic respiratory failure in COVID-19 patients?
Authors: Villanueva Cary Amiel G. , Cruz Marie Gene D. , Palileo-Villanueva Lia M.
Published: January 2021

KEY FINDINGSVery low-quality evidence suggests lower mortality (based on five observational studies) but higher failurerate of respiratory support (based on two observational studies) in COVID-19 patients given high-flow nasalcannula (HFNC) oxygen compared with noninvasive ventilation (NIV) and conventional oxygenation therapy.Randomized controlled trials (RCT) are urgently needed in this area.• Respiratory failure accounts for about half of deaths in patients with COVID-19.• High-flow nasal cannula (HFNC) oxygen therapy reduces the need for escalating respiratory support and improvespatient comfort compared with conventional oxygen therapy among those with acute respiratory failure.• Mortality was consistently lower in COVID-19 patients who received HFNC rather than NIV or conventionaloxygen therapy (COT) across 5 very low-quality retrospective observational studies from China.• Several international guidelines recommend the use of HFNC oxygen therapy in COVID-19 patients whodevelop acute hypoxemic respiratory failure. However, local guidelines from the Philippine Society forMicrobiology and Infectious Diseases (PSMID) and the Philippine College of Chest Physicians (PCCP) recommendagainst HFNC due to risks of transmission and paucity of direct evidence for efficacy.• Additional infection control precautions, i.e. wearing a surgical mask over the cannula, and locating in a negativepressure room, are recommended whenever using HFNC or NIV.• There are at least two ongoing trials due to be completed by the second quarter of 2021 comparingHFNC oxygenation with NIV or COT in COVID-19 patients.

IntroductionOlder adults usually have physical, psychological, and social changes that affect basic functions due to physiological aging. The objective of this study was to assess the degree of functional independence in geriatric patients and their relationship to age, level of education and time of residence.Patients and MethodsA descriptive, cross-cutting study focused on the assessment of the degree of functional independence under barthel’s index was carried out; made in residents with age ranges between 65-90 years, where an important description of the level of independence in seniors was obtained. The total population (sample) was 110 residents (57 women and 53 men). Results It showed that men have greater independence functionality (43% men vs. 32% women), corroborating this appreciation with a national census statistic performed in 2010. In addition, the results have been analyzed with its correlation and significance of the Residents’ Functional Level outcome regarding to their age, education level, and time in the institution.ConclusionsThe educational level showed a slight correlation with its physical functionality, however, no connection was found between functionality and age, nor institutionalized time. Further studies should be performed on a major scale to support static relevance.
A narrativa como resistência em Rubem Fonseca: uma leitura do conto “os pobres, os ricos, os pretos e a barriga”
Authors: Pezzini Paula Grinko , Costa José Carlos da
Published: January 2021

A partir do conto “Os pobres, os ricos, os pretos e a barriga”, inserido no livro Carne crua (2018), do escritor brasileiro Rubem Fonseca, o presente trabalho investiga as estratégias literárias do narrador e seus modos de enfretamento da realidade social passíveis de serem situados sob o signo da resistência. A discussão da problemática toma preceitos de teóricos como Sarmento-Pantoja (2014) e Bosi (2002) em relação ao conceito de resistência; Pellegrini (2001) e Jameson (1992; 1985) no que concerne à contextualização da pós-modernidade; e críticos literários como Lukács (2000) e Goldmann (1967). Além disso, utilizam-se noções históricas sobre o banditismo social de Hobsbawm (1976). Ambientada na América Latina, a escrita fonsequiana escancara realidades silenciadas − como a periferia brasileira. Por meio da estética brutalista, Rubem Fonseca utiliza do estilo cinematográfico ao construir frases entrecortadas e impactantes. A proposta deste estudo é buscar elementos temáticos e estéticos perceptíveis no interior da narrativa no que se referem à resistência do narrador. O conto, relatado em primeira pessoa, configura como narrador autodiegético um personagem que simboliza a marginalização da sociedade, a favelização da periferia e a violência diária do espaço urbano. O protagonista, ao subsistir diante das adversidades sociais, representa resistência política frente às forças opressoras de uma ideologia dominante.

Publicidade e transparência nas parcerias voluntárias
Authors: Martins Ricardo Marcondes
Published: January 2021

O Terceiro Setor é, quase sempre, caracterizado pela dependência das entidades privadas sem fins lucrativos à “ajuda” estatal. Com a expansão do fomento administrativo deu-se equivalente expansão da corrupção. Para coibi-la, foi editada a Lei 13.019/14 – Lei das Parcerias Voluntárias, cujo texto originário foi amplamente corrompido pela Lei 13.204/15. Esta última resultou da conversão da Medida Provisória 684/15, mas, por não ter homogeneidade temática com ela, é formalmente inconstitucional. Sem embargo, seja texto originário, mais enfaticamente, seja o texto vigente, de modo mais modesto, estabelecem uma série de exigências para o respeito, nas parcerias voluntárias, aos deveres de transparência e publicidade. Para compreendê-las, propôs-se uma nova classificação das parcerias, diversa da legalmente estabelecida. Ademais, examinaram-se, uma a uma, todas as respectivas imposições legais e regulamentares. O fomento administrativo estabelece uma relação especial de sujeição entre o fomentado e a Administração, impondo-se, a ambos, que deem plena publicidade a tudo que se refere à parceria administrativa.
