Over the last three decades there has been a growing interest in the field of subjective wellbeing (SWB).With the emergence of happiness economics researchers have exploring the possibility of using subjective wellbeing indicators for potential policy implications. However, despite the expanding literature on the subject there is no clear definition of subjective wellbeing, or indicators such as life satisfaction or happiness.
Aspects of Understanding Government’s Public Institutions Behavior Necessary to Design Reforms
Authors: Imre Stefan
Published: April 2016

This paper presents some aspects found by the author in his research in field of government public institutions behavior. The author started some years ago to research the modality how should prepare a conceptual transfer of management from the companies practice to government public institutions and to implement them for enhance quality of their results. The main concept of the theoretical research is based on some well-known theoretical remarks. One of this shows that the public institutions are similar entities as companies. Eventually they have higher complexity. Following this logic, the public institutions should be led by management instead public administration. Considering public management and the new public management only some attempts without solving the main problems, the author consider that implementing procedural efficiency oriented management to the government public institution is equivalent with an important changes induced by outside.

Preparing the conceptual transfer, for the first period of research was necessary to understand government’s public institution behavior. For this purpose the relational frame was the business organization. In this respect the research compares organizational behavior of companies and public institutions and their reaction to important changes. For understand similarities and differences it was necessary to discover theoretical standpoints regarding companies reaction to important changes induced by outside and main determinants from the organizational sciences literature. In the similar way was studied the public institution reaction and determinants of this to important changes, theoretically through documentary analyses of the literature of public administration.

The benchmarking between the reactions of the mentioned two entities discovered different behaviors and the main determinants of the reactions of them to a new form of leading system by management, including modern instruments as knowledge management.

The paper conclusions sustain that implementation of modern management systems to government’s public institutions should deal with a different behavior used to know at companies. In this respect, the paper highlights different aspects between companies and public institutions behavior admitting similarities on organizational structure and internal procedures.

Published: April 2016

The mechanical properties of silicate glass-ceramics were evaluated based on the compressive strength tests. It was found that Ta2O5addition improved densification, refinement of the microstructure and toughening of the bodies. The maximum compressive strength of the bodies with 1 mol% Ta2O5was increased 3-fold (245.92 ±0.3 MPa) in comparison to undoped glass-ceramics which was measured to be 89.04 ±0.3 MPa, while for 3 mol% it became 4-fold (387.12 ±0.4 MPa) greater. The addition of Ta2O5stabilized the system by controlling the biodegradation of the glass-ceramics. It effectively depressed the apatite formation as by addition of 3 mol% Ta2O5no apatite layer was observed. It may be concluded from this study that mechanical and physical properties can be improved by the addition of Ta2O5, but at a cost of bioactivity. Still the optimized composition having Ta2O5⩽ 1 mol% may provide appropriate strength of biomaterials for high load bearing applications.

Published: April 2016

Single-mode hollow-core waveguides loaded with atomic ensembles offer an excellent platform for light–matter interactions and nonlinear optics at low photon levels. We review and discuss possible approaches for incorporating mirrors, cavities, and Bragg gratings into these waveguides without obstructing their hollow cores. With these additional features controlling the light propagation in the hollow-core waveguides, one could potentially achieve optical nonlinearities controllable by single photons in systems with small footprints that can be integrated on a chip. We propose possible applications such as single-photon transistors and superradiant lasers that could be implemented in these enhanced hollow-core waveguides.
Solar thermophotovoltaics: reshaping the solar spectrum
Authors: Zhou Zhiguang , Sakr Enas , Sun Yubo , Bermel Peter
Published: April 2016

Recently, there has been increasing interest in utilizing solar thermophotovoltaics (STPV) to convert sunlight into electricity, given their potential to exceed the Shockley-Queisser limit. Encouragingly, there have also been several recent demonstrations of improved system-level efficiency as high as 6.2%. In this work, we review prior work in the field, with particular emphasis on the role of several key principles in their experimental operation, performance, and reliability. In particular, for the problem of designing selective solar absorbers, we consider the trade-off between solar absorption and thermal losses, particularly radiative and convective mechanisms. For the selective thermal emitters, we consider the tradeoff between emission at critical wavelengths and parasitic losses. Then for the thermophotovoltaic (TPV) diodes, we consider the trade-off between increasing the potential short-circuit current, and maintaining a reasonable opencircuit voltage. This treatment parallels the historic development of the field, but also connects early insights with recent developments in adjacent fields.With these various components connecting in multiple ways, a system-level end-to-end modeling approach is necessary for a comprehensive understanding and appropriate improvement of STPV systems. This approach will ultimately allow researchers to design STPV systems capable of exceeding recently demonstrated efficiency values.
Normal-dispersion microresonator Kerr frequency combs
Authors: Xue Xiaoxiao , Qi Minghao , Weiner Andrew M.
Published: April 2016

Optical microresonator-based Kerr frequency comb generation has developed into a hot research area in the past decade. Microresonator combs are promising for portable applications due to their potential for chip-level integration and low power consumption. According to the group velocity dispersion of the microresonator employed, research in this field may be classified into two categories: the anomalous dispersion regime and the normal dispersion regime. In this paper, we discuss the physics of Kerr comb generation in the normal dispersion regime and review recent experimental advances. The potential advantages and future directions of normal dispersion combs are also discussed.

Published: April 2016

Quadratic nonlinear processes are currently exploited for frequency comb transfer and extension from the visible and near infrared regions to other spectral ranges where direct comb generation cannot be accomplished. However, frequency comb generation has been directly observed in continuously pumped quadratic nonlinear crystals placed inside an optical cavity. At the same time, an introductory theoretical description of the phenomenon has been provided, showing a remarkable analogy with the dynamics of third-order Kerr microresonators. Here, we give an overview of our recent work on χ(2) frequency comb generation. Furthermore, we generalize the preliminary three-wave spectral model to a many-mode comb and present a stability analysis of different cavity field regimes. Although our work is a very early stage, it lays the groundwork for a novel class of highly efficient and versatile frequency comb synthesizers based on second-order nonlinear materials.
Towards efficient solar-to-hydrogen conversion: Fundamentals and recent progress in copper-based chalcogenide photocathodes
Authors: Chen Yubin , Feng Xiaoyang , Liu Maochang , Su Jinzhan , Shen Shaohua
Published: April 2016

Photoelectrochemical (PEC) water splitting for hydrogen generation has been considered as a promising route to convert and store solar energy into chemical fuels. In terms of its large-scale application, seeking semiconductor photoelectrodes with high efficiency and good stability should be essential. Although an enormous number of materials have been explored for solar water splitting in the last several decades, challenges still remain for the practical application. P-type copper-based chalcogenides, such as Cu(In, Ga)Se2 and Cu2ZnSnS4, have shown impressive performance in photovoltaics due to narrow bandgaps, high absorption coefficients, and good carrier transport properties. The obtained high efficiencies in photovoltaics have promoted the utilization of these materials into the field of PEC water splitting. A comprehensive review on copper-based chalcogenides for solar-to-hydrogen conversion would help advance the research in this expanding area. This review will cover the physicochemical properties of copper-based chalco-genides, developments of various photocathodes, strategies to enhance the PEC activity and stability, introductions of tandem PEC cells, and finally, prospects on their potential for the practical solar-to-hydrogen conversion. We believe this review article can provide some insights of fundamentals and applications of copper-based chalco-genide thin films for PEC water splitting.

Rule extraction tools and build models were algorithms in the field of computational intelligence: different versions of decision trees, neural networks and deep learning algorithms. The best algorithms allow for correct classification to 90% of the elements of the validation set. The design ensemble of specialized classifier algorithm increased the efficiency of decision-making algorithm to identify a set of validation to about 94%. Proper selection decision algorithm allows the estimation of the likelihood vector belonging to a complex object. Computational intelligence algorithms can be considered as a tool for extracting classification rules from the collection of data on soils on the local or regional level.

On-the-fly geometrical calibration fine-tuning of a mobile C-arm CBCT system
Authors: El Hakimi Wissam , Sakas Georgios
Published: April 2016

C-arm cone-beam computed tomography (CBCT) offers CT-like 3D imaging
capabilities while being appropriate for interventional suites. 3D
images are reconstructed based on 2D projections gathered during the
rotation of the C-arm around the object under investigation. It is
mandatory to provide accurate geometrical projection parameters for
each acquired 2D image, otherwise significant CT artifacts may be
induced in the reconstructed 3D volume. Usually, a pre-calibration
(offline calibration) using an X-ray phantom is preformed under the
assumption that the C-arm motion is reproducible. Thereby, stochastic
misalignments due to the open design of mobile C-arm CBCT systems are
not considered. In this article we introduce a novel online
calibration algorithm to compensate stochastic mechanical
inaccuracies. The performance of the proposed method is demonstrated
on simulated and real data.

Published: April 2016

The modest, functional bungalow provided affordable housing for millions of homeowners as California’s population exploded and its cities spread outward over the course of the twentieth century. But in the twenty-first century, when land is more expensive and we’re aware of the ecological cost of urban sprawl, a new model is needed. The author discusses what made the California bungalow such a successful mode of middle class housing, and what new experimental models might take its place, including small lot subdivisions and cohousing.
An Analysis of Partial DNA Sequence of Meisa1 Gene on Sweet and Bitter Cassavas (Manihot esculenta Crantz.)
Authors: Roslim Dewi Indriyani , Nisa Fitriyatun , Herman Herman
Published: April 2016

Sweet and bitter taste on cassava tuber is affected by starch metabolisms. Meisa1 gene is a gene in cassava (Manihot esculenta Crantz.) encoding isoamylase1 enzyme involved in starch metabolisms. This study aimed to analyze partial DNA sequences of Meisa1 gene on sweet and bitter cassavas collected by Genetics Laboratory, Department Biology, Faculty of Mathematics and Natural Sciences, Riau University, Indonesia. Methods included total DNA extraction from fresh young leaves of cassava using CTAB buffer, polymerase chain reaction (PCR), electrophoresis, and sequencing. The obtained data were analyzed using MEGA software version 5. The results showed that there were nucleotide variations in the intron region, not in the exon region. The variations were caused by the transition substitution mutation (35.39%) and transversion substitution mutation (64.61%). The genetic distance range between seven cassava genotypes was approximately 0% to 11%. Partial DNA sequence variations of Meisa1 gene located in intron region were unable to cluster seven cassava genotypes separately into two groups based on tuber taste.

Objective

The high expression of somatostatin receptor subtype 2 (SSTR2 also known as sst2) usually present in growth hormone (GH)-secreting adenomas is the rationale for therapy with somatostatin analogs (SSAs) in acromegaly. Although SSTR2 expression is a good predictor for biochemical response to SSA treatment, we still face tumors resistant to SSAs despite high SSTR2 expression. Recently, beta-arrestins (β-arrestins) have been highlighted as key players in the regulation of SSTR2 function.

Design

To investigate whether β-arrestins might be useful predictors of responsiveness to long-term SSA treatment in acromegaly, we retrospectively evaluated 35 patients with acromegaly who underwent adenomectomy in two referral centers in The Netherlands.

Methods

β-arrestin mRNA levels were evaluated in adenoma samples, together with SSTR2 (and SSTR5) mRNA and protein expression. Biochemical response to long-term SSA treatment (median 12 months) was assessed in 32 patients.

Results

β-arrestin 1 and 2 mRNA was significantly lower in adenoma tissues from patients who achieved insulin-like growth factor 1 normalization (P= 0.024 andP= 0.047) and complete biochemical control (P= 0.047 andP= 0.039). The SSTR2 mRNA was higher in SSA responder patients compared with the resistant ones (P= 0.026). This difference was more evident when analyzing the SSTR2/β-arrestin 1 and SSTR2/β-arrestin 2 ratio (P= 0.011 andP= 0.010). β-arrestin 1 and 2 expression showed a significant trend of higher median values from full responders, partial responders to resistant patients (P= 0.045 andP= 0.021, respectively). Interestingly, SSTR2 protein expression showed a strong inverse correlation with both β-arrestin 1 and 2 mRNA (ρ= –0.69,P= 0.0011 andρ= –0.67,P= 0.0016).

Conclusions

Low β-arrestin expression and high SSTR2/β-arrestin ratio correlate with the responsiveness to long-term treatment with SSAs in patients with acromegaly.
Hypoglossal Nerve Stimulator Implantation in an Adolescent With Down Syndrome and Sleep Apnea

Published: April 2016

Obstructive sleep apnea (OSA) is more common in children with Down syndrome, affecting up to 60% of patients, and may persist in up to 50% of patients after adenotonsillectomy. These children with persistent moderate to severe OSA require continuous positive airway pressure, which is often poorly tolerated, or even tracheotomy for severe cases. The hypoglossal nerve stimulator is an implantable device that produces an electrical impulse to the anterior branches of the hypoglossal nerve, resulting in tongue protrusion in response to respiratory variation. It is an effective treatment of sleep apnea in select adult patients because it allows for alleviation of tongue base collapse, improving airway obstruction. Herein we describe the first pediatric hypoglossal nerve stimulator implantation, which was performed in an adolescent with Down syndrome and refractory severe OSA (apnea hypopnea index [AHI]: 48.5 events/hour). The patient would not tolerate continuous positive airway pressure and required a long-standing tracheotomy. Hypoglossal nerve stimulator therapy was well tolerated and effective, resulting in significant improvement in the patient’s OSA (overall AHI: 3.4 events/hour; AHI: 2.5–9.7 events/hour at optimal voltage settings depending on sleep stage and body position). Five months after implantation, the patient’s tracheotomy was successfully removed and he continues to do well with nightly therapy.
Strategies of persuasion in offers to participate in cancer clinical trials II: Appeals to altruism
Authors: Barton Ellen , Eggly Susan , Winckles Andrew , Albrecht Terrance L.
Published: April 2016

Recent research has suggested that altruism might play a role in patients’ decisions to participate in cancer clinical trials. Little is known, however, about oncologists’ use of appeals to altruism as a persuasive strategy in the face-to-face communication of offers to participate in clinical trials. Based on a corpus of 22 oncology encounters, this exploratory discourse analysis describes oncologists’ appeals to altruism in clinical trial offers and discusses the ethical status of such appeals. Oncologists make appeals to altruism (1) in discussions of trial benefits and (2) in research stories about the progress of medical science through clinical trials. But these appeals were made only rarely in the corpus, indicating that oncologists may not regard appeals to altruism as a persuasive strategy, perhaps because they regard these appeals as ineffective in recruiting patients to participate in clinical trials.
Microstructure Invariance in U.S. Stock Market Trades
Authors: Kyle Albert S. , Obizhaeva Anna A. , Tuzun Tugkan
Published: April 2016

This paper studies invariance relationships in tick-by-tick transaction data in the U.S. stock market. Over the 1993–2001 period, the estimated monthly regression coefficients of the log of trade arrival rate on the log of trading activity have an almost constant value of 0.666, strikingly close to the value of 2/3 predicted by the invariance hypothesis. Over the 2001–14 period, the estimated coefficients rise, and their average value is equal to 0.79, suggesting that the reduction in tick size in 2001 and the subsequent increase in algorithmic trading resulted in a more intense order shredding in more liquid stocks. The distributions of trade sizes, adjusted for differences in trading activity, resemble a log-normal before 2001; there is clearly visible truncation at the round-lot boundary and clustering of trades at even levels. These distributions change dramatically over the 2001–14 period with their means shifting downward. The invariance hypothesis explains about 88 percent of the cross-sectional variation in trade arrival rates and average trade sizes; additional explanatory variables include the invariance-implied measure of effective price volatility.
Political Conflict and Foreign Portfolio Investment: Evidence from North Korean Attacks
Authors: Yook Youngsuk , Gerlach Jeffrey R.
Published: April 2016

We examine the response of foreign (i.e., non-South Korean) investors to escalating political conflict and its impact on the South Korean stock market surrounding 13 North Korean military attacks between 1999 and 2010. Using domestic (i.e., South Korean) institutions and individuals as benchmarks, we evaluate the trading behavior and performance of foreign investors. Following attacks, foreigners increase their holdings of Korean stocks and buy more shares of risky stocks. Performance results show foreigners maintain their pre-attack level of performance while domestic individuals, who make the overwhelming majority of domestic trades, perform worse. In addition, domestic institutions improve their performance. Overall, the results are consistent with the predictions based on the benefits of international diversification. Unlike domestic individuals, foreigners trade more shares than usual and deviate from their general strategy of positive feedback trading.

Published: April 2016

Various options for medical treatment of children with compression fractures of the thoracic and lumbar spine include unloading of damaged segments by simultaneous or gradual reclination (e.g., functional traction and reclination of the spine); measures aimed at building and strengthening the muscular “corset” of the back; and the use of orthotic devices of various designs (e.g., fixating-discharging, fixating-correcting corsets, orthoses on a modular basis). Questions regarding the early and late use of orthotics in patients with compression fractures of the vertebral bodies are discussed. Literature analysis, considering different methods used in the treatment of these patients in terms of their effectiveness to restore the height and shape of the damaged spinal segment revealed the absence of a differentiated approach for choosing treatment and selection criteria for orthopedic management.
Temporalização e espacialização nas distopias de Haruki Murakami e George Orwell em 1Q84/1984
Authors: Francisco Rafael da Cunha Duarte
Published: April 2016

O presente trabalho tem como seu principal objetivo pensar as questões da espacialização e da temporalização da distopia no romance 1Q84 do escritor japonês Haruki Murakami a partir de uma comparação com a obra homônima escrita por George Orwell. Procuramos pensar como esse processo de uma narrativa temporalizada no romance de Orwell é apropriado e transformado pelo projeto estético de Murakami. Portanto, a nossa investigação se concentrará em tentar refletir sobre esse processo de espacialização da distopia, levado a cabo por Haruki Murakami em seu romance, procurando pensar como ele é capaz de inaugurar também uma nova experiência do tempo na qual a distopia não mais se encontra no futuro distante mas sim no passado (ou no presente) dos seus leitores. O ano de 1984 que em George Orwell virou símbolo do terror que estava à espreita de seus leitores e leitoras, agora – em 2009 – é retomado por Murakami como um passado distópico, como um outro lugar no qual o terrível mundo de 1Q84 tem lugar. Funda-se assim uma distopia espacializada que é, ao mesmo tempo, uma distopia do passado.
Nietzsche, Plato and the Power of the Duende: The Shamanic Roots of Poetry
Authors: Lima Marcel de
Published: April 2016

This article deals with the shamanic roots of poetic achievement by way of analyzing the ancient Greek art-deities, namely Apollo and Dionysus, in their sharp opposition of artistic tendencies as they are presented by Friedrich Nietzsche in his reappraisal of Platonic considerations on artistic creation. This first analysis is soon followed by an interesting parallel to the Nietzschean force of the Dionysian that can be found in the equally mysterious power of the “Duende,” present in Federico García Lorca’s fusion of Surrealist concerns with his sense of native Andalusian culture, as a means to show the shamanic roots of poetic representation.

Published: April 2016

O objetivo deste estudo foi analisar o risco de cárie em indivíduos com Síndrome de Down (SD) utilizando o Software Cariogram®, associando aos indicadores salivares. Participaram do estudo 124 pacientes, entre 6-52 anos, 62 indivíduos SD e 62 indivíduos controles sem a síndrome. Foram recolhidos dados sobre dieta, uso de flúor, pH salivar, capacidade tampão e contagem de Streptococcus mutans. Os resultados mostraram que os indivíduos SD apresentaram maior índice de placa, capacidade tampão e fluxo salivar reduzidos. A hipossalivação mostrou uma associação moderada com índice CPOD e índice de placa. Na análise Cariogram® verificou-se alto risco de cárie nestes pacientes, e dada a importância e facilidade deste método de diagnóstico, sugerimos que seu uso seja ampliado como uma ferramenta importante para facilitar o controle da cárie em indivíduos SD.

Published: April 2016

Os estudos clínicos boca-dividida são muito usados nas pesquisas odontológicas. Esse desenho de estudo epidemiológico tem sido preferível, principalmente por reduzir em grande parte a variabilidade interindividual, bastante presente nos ensaios clínicos do tipo paralelo e que poderia interferir negativamente nos efeitos do tratamento. No entanto, é necessário que tanto o pesquisador clínico quanto o estatístico conheçam claramente todas as características do estudo boca-dividida, incluindo suas vantagens, desvantagens, considerações sobre a análise estatística mais adequada e suas implicações clínicas, para que sua utilização seja feita de maneira correta.

The effects of gamma radiation (control, 0.25kGy, 0.50kGy, 0.75kGy, 1.00kGy) and dip treatment of liquid paraffin wax (12%) on the physico-chemical quality of freshly harvested dried water chestnut (Trapa bispinosa Roxburg), packed in glass jar, tin container and low density polyethylene (250 gauge), and the radiation sensitivity of lesser grain borer in gamma radiated samples was analyzed by inoculation of 15 lesser grain borer pest during a period of 6 months at room temperature. The data on the basis of physical properties revealed that weight loss, damage per cent and number of lesser grain borer was found to be 8.93-14.46, 6-24.5 percent and 2-18 borers. The chemical composition ranged from viz; moisture (9.40-10.10), protein (8.82-8.87), fat (0.90-1.00), carbohydrate (76.83-76.87), total ash (3.15-4.03). The effect of gamma radiation and liquid paraffin wax coating on total sugar, reducing sugar, phenol and acidity, and ascorbic acid were from 5.83-5.88, 1.84-1.87, 0.14-0.16, 0.11-0.12 per cent and 41.66-50.00mg/100g respectively. Statistical analysis reveals significant difference in physical parameters (weight loss and damage percent) however in case of chemical composition, throughout the storage period a marginal changes was observed in 0, 3 and 6 months. Irradiation had no appreciable effect on chemical parameters. The treatment combination W4R4 (12% liquid paraffin wax and 1.00kGy) stored in tin container was found to be the best and can extend shelf life up to 6 month without losing the quality of stored water chestnut.

Fewer than four years ago, melamine was a term known only to chemists although its use as a diuretic was studied 65 years ago. This changed almost overnight in 2007 when the pet food scandal broke out. Later in 2008, the much more serious melamine-adulterated milk powder scandal occurred in China. Ingestion of melamine-adulterated milk and other animal products could lead to fatal renal failure and even death. Melamine is an organic nitrogenous compound used in the production of plastics, dyes, fertilizers, and fabrics. It has an high nitrogen content of 667g/kg, which may correspond to a crude protein (CP) level of 4168.75 g/kg (N x 6.25). Hence, melamine is added intentionally to protein foods such as wheat gluten, corn gluten, rice protein, soya and fishmeal to falsely increase their apparent protein content, which are used for making livestock and poultry feed. The toxic effects of melamine, include nephroliths, chronic nephritis and bladder carcinoma in animals. Feeding of melamine contaminated diets to broiler chicken resulted in mortality and other production losses like reduced weight gain, increased feed conversion ratio (FCR) and tissue residues mainly in muscles of birds.
Genome modifications in crops employing engineered nucleases

Crop improvement aims at substantial enhancements in the quality, yield and stress resistance of crops to meet the increasing food demand of growing world population. Targeted genome modification of crop plants is one of the ways to achieve this. This technology supersedes conventional methods limited by the inefficiencies of random mutation, accuracy and stability. It employs site-directed nucleases to create breaks at specific points in the target genome for desired alteration with high-precision. There are four nucleases namely, LAGLIDADG homing endonucleases (LHEs), zinc finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs) and clustered regularly interspaced short palindromic repeats (CRISPR) nucleases out of which three, ZFNs, TALENs and CRISPR have been highly studied and evaluated in various crop systems for economic trait. Potency of engineered nucleases lies in their efficacy to bring desired modification in diploid as well as in polyploid plant genomes. Modifications using genome editing are similar to natural or conventional method like induced mutations and are foreseen to waive regulatory actions as applicable to genetically modified organisms. This review seeks to emphasize on the employment of engineered nucleases in various crops plants till date.

Published: April 2016

La automedicación es una práctica de riesgo cuyas consecuencias incluyen el enmascaramiento de la enfermedad, las reacciones adversas, interacciones de medicamentos, el aumento de la resistencia a ciertos tipos de drogas y las drogodependencias. Objetivos: Determinar la frecuencia de automedicación en los consumidores de medicamentos que acuden a los establecimientos farmacéuticos de un distrito de Lima Metropolitana y las variaciones de las tasas según edad, sexo y grado de instrucción. Material y métodos: Estudio observacional, descriptivo y trasversal, aplicando una encuesta durante los meses de setiembre a noviembre de 2013. La selección de la población fue por muestreo sistemático. Participaron 406 usuarios de establecimientos farmacéuticos del distrito de Pueblo Libre. Resultados: La frecuencia de automedicación en el distrito de Pueblo Libre fue 56,65% (IC 95% 0,4985 – 0,6302). El 36,09% fue en jóvenes de 18 a 24 años, el 51,30% fue de sexo masculino y el 58,70% tenía nivel de estudio básico (primario y secundario). Los tipos de automedicación más frecuentes fue la sugerida por el propio usuario en un 49,13% y la sugerida por los familiares en un 21,74%.El síndrome doloroso fue la causa más importante de automedicación en 40,35% y los tipos de fármacos más adquiridos fueron los AINE 30%, los antigripales 20,87%, medicamentos gastrointestinales 15,22%, los analgésicos 8,67%, los antialérgicos 7,39% y los antibióticos 4,35%. Conclusiones: La automedicación en los consumidores de medicamentos que acuden a los establecimientos farmacéuticos fue alta.
“Kissing abscess” de la valva anterior mitral y pseudoaneurisma por endocarditis infecciosa de la válvula aórtica
Authors: Cornejo Marilhia , Gamero María , Soria Jorge , Rotta Aida , Dueñas Roy
Published: April 2016

Un mecanismo inusual de complicación de endocarditis infecciosa (EI) aórtica es llamado “kissing abscess”, producido por el impacto del flujo de la regurgitación aórtica y contacto de las vegetaciones sobre la valva anterior mitral. Los abscesos de la válvula mitral pueden complicarse con pseudoaneurismas. Se presenta el caso de un varón de 36 años con fiebre y sudoración de tres meses de evolución. Además, soplo diastólico aórtico y hepatomegalia. La ecocardiografía transesofágica (ETE) mostró válvula aórtica bicúspide con insuficiencia severa y perforación del seno no coronariano con múltiples vegetaciones de tamaño promedio de 4 mm, válvula mitral anterior con imagen anecogénica de 14 mm que corresponde a absceso con flujo Doppler en su interior y otra imagen anecogénica de pseudoaneurisma y múltiples vegetaciones subvalvulares. La extensión de la infección de la EI aórtica a la válvula mitral es una complicación con alta tasa de mortalidad, por ello es necesario el diagnóstico temprano.

Solutions of the modified Kawahara equation with time-and space-fractional derivatives
Authors: Safavi M. , Khajehnasiri A. A.
Published: April 2016

In this paper, we consider fractional differential equations (FDEs), specially modified Kawahara equation with time and space fractional derivatives, also we use Adomian decomposition method (ADM) to approximate the exact solutions of this equation. The ADM method converts the FKEs to an iterated formula that approximate solution is computable. The numerical examples illustrate efficiency and accuracy of the proposed method.
Nuevas formas de trabajo en la sociedad del conocimiento: el teletrabajo
Authors: Hormigos Ruiz Jaime
Published: April 2016

Una de las características fundamentales de la nueva economía global es la exigencia de mejorar la competitividad tanto de empresas como de países con el fin de poder competir en el mercado. Ya no se compite con una empresa cercana que tiene las mismas circunstancias legales, sociales, demográficas, culturales o políticas, sino con empresas de todo el mundo cuyo entorno es totalmente diferente; en cuanto a su regulación legal, en cuanto a las cualidades del factor humano al que tiene acceso, diferente en un conjunto de factores de los que depende la capacidad productiva. La nueva economía globalizada afecta a todas las empresas, sean del tamaño que sean. Por este motivo, todas las organizaciones deben adaptarse a estas nuevas coordenadas que impone el mercado global. La existencia de este mercado global ha sido posible gracias a la presencia de las nuevas Tecnologías de la Información y de las Comunicaciones (TIC) que han facilitado el desarrollo de un mercado a escala mundial, gracias a ellas se ha producido el fenómeno de la desubicación, por medio del cual el trabajo ya no es necesario realizarlo en un lugar físico determinado, donde se reúnan todos los integrantes de la empresa. De esta forma aparece la máxima representación de la flexibilidad de la nueva empresa y con ella las nuevas formas de entender el trabajo. Pero además debemos ser conscientes de que la rapidez con la que se está asimilando el uso de las nuevas tecnologías provoca una aceleración aún mayor del cambio, no sólo en la forma de trabajar, sino también en la forma de vivir.
Fugitivos del hogar

Al hecho claro de que la socialización del niño español se hace hoy más fuera que dentro del hogar, se añade la circunstancia de que no se sale del mismo al final de la adolescencia, como se hacía: desde tiempo inmemorial hasta ayer, como se sigue haciendo en muchos países occidentales; quizá (caso estupendo) ni a los veinticinco o treinta, y entonces se cuadra la paradoja: por un lado, el hogar familiar se habita tan poco que las habitaciones pasan a denominarse, han pasado a ser, meros dormitorios; hasta la biblioteca puede llamarse dormitorio; por otro, tan singular socialización, que estorba la autonomía de la personalidad en desarrollo, no les impide a los chicos quedarse en la casa paterna hasta mucho después de la adolescencia. Hijos y padres educados todos en el barullo cotidiano -sobrinos, suegros, etcétera- configuran así un peculiar e inextricable universo que se combina con la vida conversada del bar y con la movida correspondiente. La viveza incomparable de los bares españoles, más numerosos que los de muchos otros países juntos, depende menos de su posible comodidad que de una vida familiar que expulsa tanto como atrae; el bar se nutre en buena medida de la imposible habitabilidad de tales viviendas-dormitorios, de los constantes ruidos de vecinos incapaces de ensimismamiento. Dicen que ahora el paro dificulta y viene de muy atrás! y no se sabe si la disminución del paro, que amontona a la gente en pisos ridículos donde mayormente se conversa a voz en grito y se oye la radio y se ve la televisión en pantalla grande, resolverá el problema que nos ocupa.

Published: April 2016

Case:

A nine-year-old boy had multiple osteochondromas in the hands, feet, and tibiae, many of which pointed toward the adjacent joint. Although several were treated surgically, others resolved spontaneously. A heterozygous mutation in the PTPN11 gene was identified by genetic analysis of peripheral blood, so the patient was diagnosed with metachondromatosis despite the absence of enchondromatous lesions.

Conclusion:

To the best of our knowledge, this is the first reported case of a patient with metachondromatosis without any enchondromatous lesions.
Exertional Compartment Syndrome with Amniotic Band Disruption Sequence
Authors: Wall Lindley B. , Butler Lesley , Ezaki Marybeth , Oishi Scott N.
Published: April 2016

Cases:

We report the cases of two female patients who presented with symptoms of lower-extremity exertional compartment syndrome years after initial amniotic band reconstruction. These patients underwent extensive fascial release for treatment of amniotic band disruption sequence (ABDS) of the lower extremity, with resolution of their symptoms. We describe our current technique that is now performed at the time of initial reconstruction for addressing all layers of the deformity.

Conclusion:

The surgical reconstruction of ABDS requires addressing all layers of the deformity. Failure to do so may lead to long-term sequelae. Both patients in this report had exertional compartment syndrome following incomplete fascial release at their primary surgery, requiring subsequent fasciotomies.
