TIMING OF SURGICAL INTERVENTION AFTER VENTRICULAR SEPTAL RUPTURE
Authors: Kiliptari Guliko
Published: April 2020

Ventricular septal rupture (VSR) is a rare but lethal complication of acute myocardial infarction (AMI). patients presenting with ST-elevation MI (STEMI) were evaluated for heart rupture (VSR ) based on reperfusion strategy. , After undergoing a primary percutaneous coronary intervention (PCI), VSR was reported to occur in 0.23-0.71% of patients. Post-infarction VSR carries significant mortality (36.%) despite aggressive surgical management. Rupture develops after full-thickness (transmural) infarction of the ventricular septum and can occur at any anatomic location. Ventricular septal rupture is likely to be associated with total occlusion of the infarct-related artery. the newly formed communication results in left to right shunting of oxygenated blood from the high-pressure left ventricle to the lower-pressure right ventricle. .Mortality was highest in patients who underwent operation in the first 24 h, consistent with other investigators. The case reflects the important problem after myocardial infarction , ventricular septal rupture and challenges the timing of intervention
Patient 70 year old,male,caucasion was admitted in our hospital with encephalopathy and hypotension.ECG revealed ST segment elevation in II,III,AVF,V4-V6 lead,ST segment depression in AVL,V1-V3 lead. Koronarography detected left main artery without important stenosis, 95 % stenosis of middle segment and 75% stenosis of distal part of left anterior descending artery.40% stenosis of middle segment of right coronary artery, occlusion of posterior descending artery.After recanalization and balloon predilatation of posterior descending artery, was parformed drug eluted stant implantation. transthoracic echocardiography (TTE) detected of postinfarction VSR (pict 3). The Colour Doppler was demonstrated of flow across the septum and left to rigt shunt.
Conclusion: Ventricular septal rupture (VSR) is a rare but lethal complication of acute myocardial infarction (AMI). Mortality of patients is significantly depending o n timing of surgery. Operative management of patients can be complex, and having a systematic approach is helpful. The cornerstone of medical management of VSR is afterload reduction, and may be considered routine care.. According our case , surgical intervention was delayed and dispite adequate treatment patient was died . There is no clear evidence to guide the surgical management of patients who are in shock, as all approaches have shown extremely high mortality. Possible strategies include emergent surgery on individuals with marked haemodynamic instability and circulatory compromise.
STABILITY OF A SMART WALKER IN FALL RELATED EVENTS
Authors: Seabra Eurico
Published: April 2020

The development of a gait disorder leads to the loss of the ability to walk and increases the frequency of fall events. To help improve the lives of people affected by reduced mobility and return the patient’s own dependency and confidence, smart walkers (SW) are used to empower the user’s residual capacities and promote functional recovery. An example presented in this paper is the ASBGo Smart Walker, a customized motorized rehabilitation tool that provides an innovative combination of real-time multimodal sensory information. The design of this augmentative device is centered on safety and stability, both fundamental to provide rehabilitation to the affected individuals. In this paper, it is presented an assessment of the ASBGo Smart Walker’s stability during forward and lateral falls. To evalute if the SW has the ability to support the patient during a fall and not overturn, leading to fatal falls, theoretical stability tests were performed. These tests proved and verified the safety of the ASBGo SW, in most of the conditions and situations when the device is handled. Nonetheless, in order to minimize fall-related impact it is proposed in future work the implementation of prevention methods and strategies.
GEORGIAN TOURISM INDUSTRY – SPECIFICATIONS OF DEVELOPMENT, PROBLEMS, PROSPECTIVE
Authors: Mikashavidze Vakhtang
Published: April 2020

Tourism development is one of the priority directions of the Georgian economy, since this sector significantly ensures the socio-economic growth of the country, hence, raising the level of living of the population.
Therefore, in the modern stage, it is vitally necessary to implement state policy in the country, which will facilitate solving problems in the field of tourism and sustainable development of the sector. These are the issues discussed in the work – “Georgian Tourism Industry – Specifications of Development, Problems, Prospective”. The article notes that despite the many political and socio-economic problems accumulated in the country, travelers and tourists flows intensively, which is a positive result of the development of the sector. However, unfortunately, the negative impact of humanity on the nature is strengthened, which is evident in most types of tourism.
The article indicates the possibility of avoiding negative ecological processes with reasonable management of anthropogenic negative impact. These requirements are most fully answered by ecological tourism - controlled form of the natural tourism.
The research proves that the mass scale of tourism causes not only a negative ecological impact on nature, in addition, it can not answer the challenges facing the country - the sustainable development of the country and the increase in income from tourism, increasing the importance of the sector.
As a result of the survey, it is confirmed that for the substantial increase of income received from the tourism service of Georgia is necessary to change the structure of the visitors arriving in the country; In particular, to increase the number of tourists with high paying potential at the expense of decreasing share of mass tourists.
To do this, it is necessary to develop and implement such activities, which will make Georgia's natural and cultural resources as world-class tourist products and creates the possibility of making unique impressions. It will facilitate attracting high-paying contingent from EU countries, North America and Asia.
The number of tourists with such potential would reduce the risk factors associated with environment and finances and ensure the increase of the state treasury, as well as ensured the socio-economic development of the country and the importance of the sector. The complex of the event is proposed the practical implementation of which promotes tourism business development to improve macroeconomic, institutional, social and legal environment; The necessity of development of tourism business development strategy and action plan is proven.

Nilai-nilai Desain Dalam Praktik dan Berpikir Desainer: Filosofi "Jalan Kayu" Barata Sena
Authors: Utomo Tri Noviyanto P , Kusumarini Yusita
Published: April 2020

Dalam paradigma baru tentang peran dan tanggungjawab desainer menyatakan bahwa tidaklah cukup bagi desainer hanya membuat gambar dan memproduksi karya desain saja. Desainer  juga perlu memproduksi, membangun serta menciptakan nilai-nilai desain di dalam setiap karya yang diciptakannya. Bagaimana membangun tanggungjawab dan memproduksi nilai-nilai desain secara kongkrit bagi desainer saat ini menjadi topik bahasan yang penting untuk dielaborasi lebih lanjut. Melalui studi kasus yang dilakukan terhadap salah satu desainer produk interior/furnitur yang cukup unik di kota Solo, penelitian ini akan menggambarkan dan menganalisa secara deskriptif bagaimana seorang Barata Sena dengan kerangka berpikir filosofisnya yang dikenal sebagai “Jalan Kayu” membangun serta memproduksi nilai-nilai desain melalui perancangan produk Art Furniture. Nilai-nilai desain yang tertanam dari filosofi “Jalan Kayu” yaitu “menerima, memberi dan melepaskan” ternyata sejalan dengan pemikiran Papanek tentang nilai sosial dan moral desainer dalam praktik-praktik perancangan yang menekankan fungsi produk dan tanggungjawab desainer terhadap kesejahteraan dan kemanusiaan. Nilai-nilai desain ini juga beririsan serta bermuara pada konsep besar dari Triple Botton Line of Design (Planet, People, Profit) sebagai tujuan besar sustainable development global.

Políticas públicas de apoio à agricultura familiar:
Authors: Mattei Lauro
Published: April 2020

O Programa Nacional de Fortalecimento da Agricultura Familiar (PRONAF) foi criado em 1996 com o objetivo de estimular a expansão da agricultura familiar no Brasil. Observa-se que o programa se disseminou rapidamente por todas as grandes regiões, encontrando-se atualmente em praticamente todos os municípios do país. Do ponto de vista operacional, o programa concentra-se em quatro grandes linhas de atuação, a saber: a) Financiamento da produção; b) Financiamento de infraestrutura e serviços municipais; c) Capacitação e profissionalização dos agricultores familiares; d) Financiamento da pesquisa e da extensão rural. Neste artigo as atenções se concentraram na modalidade do financiamento da produção dos agricultores familiares. Dentre os principais resultados observou-se uma expansão do programa para todo o país, acompanhada por aumentos graduais do volume total de recursos do crédito rural. Todavia, verificaram-se problemas operacionais dessa política pública, uma vez que os recursos encontram-se fortemente concentrados na região Sul e no segmento dos agricultores familiares já consolidados.

No presente artigo analisa-se a ação de indivíduos que lutam pelo acesso e manutenção da terra, operando com a dialética entre a moral camponesa e as perspectivas contemporâneas de inserção social. Focaliza-se a relação entre os iguais e os desiguais, entre coletivos e indivíduos, entre identidades e diferenças estabelecidas com os “outros”, a partir da experiência dos que vivem no Assentamento Bela Vista (Esperança - PB). A metodologia conjugou a observação participante, entrevistas orais e as notas no diário de campo. As narrativas orais construídas a partir do trabalho da memória foram analisadas conforme as identidades reconstruídas e (re) significadas em relação às “lutas” do passado e do presente, no espaço social e simbólico, as quais têm gerado novas dinâmicas, alterando a configuração do território e das relações sociais. Destacamos que a luta pela terra não se constitui a partir de pessoas com identidades totalmente diaspóricas; do nosso ponto de vista e a partir da pesquisa realizada, podemos afirmar que a mesma se faz por meio da resistência, na qual se buscou efetivar um projeto orientado por uma economia moral camponesa. Os posseiros se envolveram no processo de luta social motivados por um senso de justiça, reivindicando o direito sobre a terra da qual estavam sendo “expulsos”. A resistência permitiu transformar suas identidades de posseiros para assentados, chegando à propriedade privada e definitiva da terra, reconhecendo-se atualmente enquanto agricultores. Orientam-se pela economia moral camponesa, que lhes dá subsídios para agirem socialmente e para resistirem, lançando mão de várias estratégias para continuar na terra e para escapar da seca, ao passo que pleiteiam programas públicos e participam dos jogos sociopolíticos locais, que ultrapassam os limites do assentamento.
Resistencias al modelo extractivo exportador:

El presente trabajo tiene por objetivo abordar las características que asumen las resistencias sociales que emergen frente al despliegue del modelo extractivo exportador, particularmente, aquellas que se originan a partir de la expansión de la minería metalífera a gran escala. A tal fin, proponemos el análisis del conflicto que se suscita en la provincia de La Rioja (Argentina), territorio en el cual el impulso de la megaminería evidencia el proceso de mercantilización de los bienes de la naturaleza y también la disputa en torno a los modelos de desarrollo. En efecto, mientras que otras provincias integrantes del núcleo duro del “modelo minero” – nos referimos a San Juan y Catamarca – cuentan actualmente con proyectos en explotación, lo que supone la constitución de las empresas como actores territoriales, esto no acontece en La Rioja. El conflicto socioambiental que presentamos tiene, desde el año de 2006, como epicentro el Valle de Famatina, región donde la movilización social impidió el inicio de la explo- tación aurífera a cielo abierto.

Role of Public Organic Procurement Policies (POPP’s) in the implementation of organic food and farming strategies:
Authors: Mikkelsen Bent Egberg , Lundø Martin
Published: April 2020

Targeting public procurement policies has become an important goal for European policy makers since it is believed to contribute to more sustainable food systems and food consumption patterns. Food purchased by the public for institutions such as hospitals, care homes, universities, prisons, schools, armed forces and canteens represent a significant part of the food economy in European countries. As a result governments at different levels have adopted policies that promote organic food and farming in many countries. Since agencies and institutions of the public can be expected to be influential by setting good examples of food consumption, the food for the public plate has come to take a much more visible role in public service provision policymaking over the past decades. However, for such strategies to be effective the right policy mix is essential. This paper reports on the Danish case of Public Organic Procurement Policy (POPP’s) and its role in organic food and farming strategies. It gives a brief account on component of the policy mix including the setting up of a labelling system, a monitoring system for sales volumes and a foodservice workers training program. The paper examines the first results from the monitoring system and provides insight in the progress of POPP’s. It details the implementation and maintenance of the monitoring program and discusses the role of metrics in relation to other policy tools as well as the contribution that monitoring can make in terms of policy implementation.
Management Strategies of Working Capital in Polish Services Providing Companies
Authors: Zimon Grzegorz
Published: April 2020

Net working capital aims at keeping companies in good financial condition and, above all, ensuring their financial security. It appears in micro, small, medium and large companies operating in every sector. In the case of services providing companies working capital management is very limited as in such businesses there is no inventory, which is the least liquid element of current assets. Therefore, in such companies working capital management strategies are based on the management of short-term receivables, short-term investments and short-term liabilities. In the paper services providing companies operating in the transport and tourism sectors have been presented. The research period covers the years 2016-2018. By means of selected statistical methods and appropriate financial indicators it was found that transport companies used different working capital management strategies compared to companies operating in the tourism sector.

Wilson’s disease is a genetic autosomal recessive transmitted pathology, that causes disorders of copper metabolism, leading to its accumulation in target tissues. It is a multisystemic affection and has a polymorphic clinical picture. Establishing a positive diagnosis can be difficult, with no single test that confirms or definitely excludes the disease. Diagnostic criteria for the Wilson disease in adult patients were established, then reevaluated for the child. Establishing early diagnosis allows early chelation therapy, which provides a better prognosis, delaying the progression of the disease. This is the reason why the importance of family screening must be emphasized.

Objectives. This study aimed to find the most frequent causes of thrombocytopenia in patients who come to the Pediatric Emergency Department and to evaluate the importance of the investigations and immediate treatment options available in the Emergency Department for the final diagnosis. Methods. The study included 73 pediatric patients (aged two months to 16 years) with thrombocytopenia evaluated in the Pediatric Emergency Department in 6 years. The final diagnosis of the patients presenting with thrombocytopenia in the Pediatric Emergency Department was recorded. We assessed the clinical characteristics and findings of the investigations of the patients diagnosed with immune thrombocytopenic purpura (ITP). Results. Most of the patients were diagnosed with sepsis (40%). The second most frequent diagnosis was ITP (34%). Values of the platelets recorded in patients with ITP were between 1,000 and 87,000 and 14/25 (56%) of the patients with values lower than 20,000/mm3. Most of the patients with ITP received i.v. immunoglobulin. Conclusions. ITP and sepsis were the leading causes of thrombocytopenia in children in the Pediatric Emergency Department in our hospital. The suspicion of malignant hematological disorders was raised based on the data from the patient’s medical history and the findings in the physical exam. Treatment with i.v. immunoglobulin in patients with ITP should only be used when patients associate active hemorrhage. The conclusions of this study allowed us to establish a protocol for the investigation and treatment of patients with ITP.

Tracheobronchial foreign body aspiration in children represents a diagnostic and therapeutic emergency in the practice of pediatricians and ENT specialists. Delaying the diagnostic and, implicitly, the bronchoscopic extraction of the foreign body can lead to complications, some even with vital prognosis. In this paper, the authors present from their personal experience two pediatric cases of tracheobronchial foreign bodies diagnosed and treated at different time intervals after the moment of aspiration.

Growth hormone deficiency is a rare cause of low stature. Early recognition of the disease results in effective treatment, leading to a final height as closely as possible to the genetic target. The authors present the case of a 1 year 2 months old girl admitted for growth evaluation in our department. She had been previously diagnosed with isolated growth hormone deficiency in an Endocrinology Unit and was now sent to complete the investigations and undergo imaging studies. The laboratory investigations excluded other pathologies. The MRI showed adenohypophysis hypoplasia, thin hypophyseal stalk. Se is started on growth hormone substitution treatment with good results.
A mudança em terapia familiar: construindo agenciamento
Authors: Biagi Berenice Araújo Dantas de , Rasera Emerson Fernando
Published: April 2020

Este artigo visa compreender o processo de produção de sentidos sobre a mudança em terapia familiar sob a perspectiva construcionista social. A análise do processo terapêutico de uma família apontou que a construção conversacional da mudança terapêutica foi marcada pelo deslocamento do discurso inicial do problema de saúde da mãe, oriundo do trabalho, para o discurso do agenciamento com o cuidado da vida. Tal construção foi analisada em relação a três aspectos centrais: (a) a desconstrução do sentido do trabalho; (b) a redefinição da relação mãe-filha; (c) a reconstrução da vida. A análise permitiu ainda compreender um importante processo subjacente, o agenciamento como forma de promover a mudança terapêutica em terapia familiar. Concluímos que a postura aberta, ativa e engajada da terapeuta com o fluxo da conversa favoreceu a emergência desses sentidos de mudança.DOI http://dx.doi.org/10.21452/2594-43632018v27n60a01

Percepção dos genitores sobre o impacto do nascimento do segundo filho nas relações familiares
Authors: Goldschmidt Bibiana Ughini
Published: April 2020

As famílias passam por ciclos de vida que podem demandar adaptações, sendo a inserção de um novo membro no contexto familiar um deles. No presente estudo, foram investigados os impactos do nascimento do segundo filho nas relações: genitores-primogênito, relação conjugal, impacto no próprio filho mais velho e nos genitores. Para isso, foram realizadas entrevistas com três casais que atendiam aos requisitos da pesquisa. Pôde-se identificar, na análise, alguns aspectos, como o afastamento dos casais em relação a atividades a dois, que o comportamento mais frequente demonstrado pelo primogênito foi de chamar atenção dos pais para ele. Demonstrou-se, também, uma aproximação dos pais em relação ao filho mais velho e as mães apresentaram uma necessidade maior de organização com a chegada do segundo filho. As estratégias de manejo mais salientadas foram de contar com a rede de apoio, principalmente com os avós maternos, e investir no diálogo com o primogênito.
High-resolution Optical Spectroscopic Observations of Comet 21P/Giacobini–Zinner in Its 2018 Apparition
Authors: Shinnaka Yoshiharu , Kawakita Hideyo , Tajitsu Akito
Published: April 2020

Comet 21P/Giacobini–Zinner is a peculiar comet from the viewpoints of the chemical and physical properties of its dust grains. We conduct optical high-resolution spectroscopic observations of the comet. The intensity ratios of forbidden oxygen lines (at 557.7, 630.0, and 636.4 nm) and ortho-to-para abundance ratios (OPRs) of water cations (H2O+) and amidogen radicals (NH2) are obtained while only the upper limit for 14N/15N in the amidogen radical is restricted. The OPRs of H2O+ and NH2 are similar to those of other comets, although the real meaning of these OPRs is still debated. Based on the observation of the forbidden emission lines of oxygen atoms, it can be concluded that the comet is depleted in CO2. In consideration with the depletion in other highly volatile species found in the near-infrared region and the presence of complex organics in comet 21P/Giacobini–Zinner, this comet might form in a warmer region in the solar nebula compared with other comets.
Improving the Lomb–Scargle Periodogram with the Thomson Multitaper
Authors: Springford Aaron , Eadie Gwendolyn M. , Thomson David J.
Published: April 2020

A common approach for characterizing the properties of time-series data that are evenly sampled in time is to estimate the power spectrum of the data using the periodogram. The periodogram as an estimator of the spectrum is (1) statistically inconsistent (i.e., its variance does not go to zero as infinite data are collected), (2) biased for finite samples, and (3) suffers from spectral leakage. In astronomy, time-series data are often unevenly sampled in time, and it is popular to use the Lomb–Scargle (LS) periodogram to estimate the spectrum. Unfortunately, from a statistical standpoint, the LS periodogram suffers from the same issues as the classical periodogram and has even worse spectral leakage. Here, we present an improvement on the LS periodogram by combining it with the Thomson multitaper approach. The multitaper spectral estimator is well established in the statistics and engineering literature for evenly sampled time series. It is attractive because it directly trades off bias and variance for frequency resolution, and is fast to compute: compared to an untapered spectral estimator, the multitaper adds no more than a couple of seconds for a time series with a million data points on a current desktop computer. Here, we describe an estimator that combines the multitaper with the LS periodogram. We show examples in which this new approach has improved properties compared to traditional approaches in the case of unevenly sampled time series. Finally, we demonstrate an application of the method to astronomy with an application to Kepler data.
Mars Upper Atmospheric Temperature and Atomic Oxygen Density Derived from the O i 130.4 nm Emission Observed by NASA’s MAVEN Mission
Authors: Qin Jianqi
Published: April 2020

The abundance of atomic oxygen is a major unknown for the Mars upper atmosphere, and systematic measurements of this key species is a primary objective of NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) mission. Moreover, the Martian dayside temperature structure and its variability has been a subject of considerable debate in the past. In this study, an inversion analysis of the periapsis limb scans of the O i 130.4 nm emission observed by MAVEN is performed to quantify the neutral temperature and atomic oxygen abundance in the Mars upper atmosphere. Our analysis yields unprecedented resolution of the spatial variation of Mars atomic oxygen, showing that its exobase density decreases with the solar zenith angle (SZA) from ∼0° to 60° by about an order of magnitude, from ∼108 to ∼107 cm−3 near perihelion (2015 April) and from ∼107 to ∼106 cm−3 near aphelion (2017 November). For a given SZA the exobase densities near perihelion are about an order of magnitude higher than those near aphelion. The [O]/[CO2] mixing ratio at 130 km altitude can vary from ∼0.1% to 4.6%, which also decreases with increasing SZA. Moreover, it is shown that the Mars exobase temperature does not vary significantly with SZA from ∼0° to ∼60°, which is estimated to be ∼239.2 ± 27.6 K near perihelion and ∼162.4 ± 19.9 K near aphelion, with a difference of 76.8 K between these two seasonal extremes.
Molecular Clumps Disguising Their Star Formation Efficiency per Free-fall Time: What We Can Do Not to Be Fooled
Authors: Parmentier Geneviève
Published: April 2020

The presence of a volume-density gradient in molecular clumps allows them to raise their star formation rate compared with what they would experience if their gas were uniform in density. This higher value for the star formation rate yields in turn a higher star formation efficiency per free-fall time that we measure. The measured star formation efficiency per free-fall time,

, of clumps is therefore plagued by a degeneracy, as two factors contribute to it: one is the density gradient of the clump gas, the other is the intrinsic star formation efficiency per free-fall time,

, with which the clump would form stars should there be no gas-density gradient. This paper presents a method allowing one to recover the intrinsic efficiency of a centrally concentrated clump. It hinges on the relation between the surface densities in stars and gas measured locally from clump center to clump edge. Knowledge of the initial density profile of the clump gas is not required. A step-by-step description of the method is provided as a tool in hand for observers. Once

has been estimated, it can be compared with its measured, clump-averaged, counterpart,

, to quantify the impact that the initial gas-density profile of a clump has had on its star formation history.
The Galactic Center Black Hole, Sgr A*, as a Probe of New Gravitational Physics with the Scalaron Fifth Force
Authors: Kalita Sanjeev
Published: April 2020

The Galactic Center black hole (Sgr A*) provides an ideal laboratory for astronomical tests of new gravitational physics. This work reports that curvature correction (f(R)) to quantum vacuum fluctuations naturally yields a Yukawa-type scalar fifth force with potential

, where M

ψ
is the mass of the f(R) scalarons. Estimating the UV and IR cutoff scales of vacuum fluctuations, the Yukawa coupling strength is connected to the scalaron field amplitude. Whereas recently constrained Yukawa coupling and range correspond to light scalarons with M

ψ
 = (1.37 × 10−21–5.49 × 10−20) eV, vacuum fluctuations yield a massive scalaron with M

ψ
 = 10−16 eV. Scalaron-induced periastron shift of stellar orbits near Sgr A* has been studied with respect to the semimajor axis in the range a = 10–1000 au. It is found that the scalarons resulting from quantum fluctuations affect the precession of orbits with a = 128–256 R

s
. The possibility of future constraints on massive scalarons in observations near Sgr A* is discussed. This is a new and independent effort to express a prototype quantum gravity effect in terms of astronomically accessible quantities.
