El ensayo de liberación de interferón gamma es un método novedoso para el diagnóstico de la tuberculosis aunque su utilidad es incierta en población pediátrica.Objetivo: examinar la utilidad diagnóstica del QuantiFERON-TB Gold (QFT-G®), uno de los ensayos de liberación de interferón gamma comerciales, en población pediátrica del Estado de Sonora, México.Materiales y métodos: estudio transversal con 160 menores de 19 años de edad, en un hospital de Sonora, México. Se compararon tres grupos, uno de pacientes con tuberculosis activa, otro con tuberculosis latente y uno más de controles hospitalizados. Los criterios de Stegen-Toledo fueron el estándar empleado. Se usó regresión logística multivariada para evaluar la asociación entre el QFT-G® y los predictores seleccionados.Resultados: la sensibilidad del QFT-G® en la tuberculosis activa fue de 76.9% y la especificidad de 90.3%. Para la tuberculosis latente la sensibilidad fue 25.0% y la especificidad de 98.6%. El QFT-G® mostró una concordancia moderada (K = 0.574) con el estándar. También mostró asociación con la radiografía de tórax sugestiva de tuberculosis (razón de momios ajustada 4.37, IC 95%: 1.42, 13.42) y con el hecho de ser caso de tuberculosis pulmonar (razón de momios ajustada 6.15, IC 95%: 1.90, 19.92).Conclusión: el ensayo de liberación de interferón gamma es un método útil para diagnosticar tuberculosis activa y puede emplearse para descartar tuberculosis latente en población pediátrica.

Published: November 2016

El carcinoma tímico es una neoplasia poco frecuente en la  población pediátrica. El diagnóstico diferencial se realiza con tumores mediastinales. Generalmente las  anifestaciones clínicas se deben a obstrucción de la vía aérea. El tratamiento incluye cirugía, quimioterapia y radioterapia. Los esquemas de tratamiento, especialmente la quimioterapia, es motivo de controversia en niños y la mayoría de los protocolos se basan en la experiencia obtenida de los adultos. El pronóstico es malo, con pocas posibilidades de curación, depende del estadio según la clasificación de Masaoka y de la posibilidad de resección quirúrgica.En este informe se describen dos casos de carcinoma tímico en niños: uno de 12 años cuya afección se inició con cianosis e hipercalcemia y en una paciente de 14 años en quien empezó con tos y dolor torácico.

Published: November 2016

Antecedentes: la ataxia-telangiectasia es una enfermedad hereditaria con patrón de herencia autosómico recesivo. Se caracteriza por deterioro neurológico, telangiectasias e inmunodeficiencia. Su causa es una mutación en el gen ATM (ataxia telangiectasia mutated) localizado en elcromosoma 11q22.3-23.1, relacionado con la síntesis de una proteína con actividad fosfoinositol-3-cinasa que participa en la regulación del ciclo celular y en la reparación del ácido desoxirribonucleico; esto explica, en parte, la susceptibilidad al desarrollo de neoplasias. Su asociación con algunos tipos de cáncer se ha establecido previamentey la mayor incidencia es con leucemias y linfomas. Se han reportado siete niñas con ataxia-telangiectasia asociada con tumores sólidos germinales, específicamente con disgerminoma.Caso clínico: mujer adolescente de 12 años con diagnóstico de ataxiatelangiectasia desde los tres años. Tuvo infecciones repetidas de las vías respiratorias que requirieron múltiples hospitalizaciones de dos a tresveces por mes; recibió tratamiento con inmunoglobulina y profilaxis antimicrobiana. A los 12 años acudió al servicio de urgencias con abdomen agudo; fue operada y se halló una masa abdominopélvica que se extirpó. El diagnóstico fue de tumor germinal mixto con componente de disgerminoma y coriocarcinoma de ovario. Recibió un primer ciclo de quimioterapia con bleomicina (10 UI/m2/día, una dosis), ciclofosfamida (1 g/m2/día por cuatro días) y cisplatino (20 mg/m2/dosis por cincodías). Se suspendió la quimioterapia porque desarrolló choque séptico que puso en riesgo su vida. Por su enfermedad de base permaneció bajo vigilancia. Actualmente, 17 meses después, la paciente vive sin actividad tumoral. Conclusión: existe asociación entre ataxia-telangiectasia, leucemia y linfomas. Se describe el caso clínico de una paciente con ataxia-telangiectasia y tumor germinal mixto con componente de disgerminoma y coriocarcinoma de ovario. Se propone establecer un tratamiento especial para estos pacientes inmunocomprometidos, con alto riesgo de cáncer pero, a la vez, de no tolerar los esquemas habituales.

Published: November 2016

El pediatra tiene un papel de primera importancia en la vigilancia y promoción del desarrollo de los niños; los padres estiman que es el profesional que puede orientarlos para saber si su desarrollo es normal y sobre la forma de proveer cuidados para favorecerlo. Para atender estas demandas el pediatra debe utilizar distintas herramientas que le permitan comprender la forma en que se va organizando el desarrollo del niño, pero a la vez la forma en que los cuidados, organización del ambiente y condiciones de riesgo y alarma pueden impactar en su evolución. No basta con aplicar pruebas de cribado, deben observarse además los procesos de crianza y la forma en qué aspectos del entorno pueden favorecer o limitar el desarrollo, acompañándose de recomendaciones claras que lo promuevan. El objetivo primario de este artículo es llamar la atención del pediatra sobre la necesidad de asesorar a los padres sobre su capacidad para vigilar y favorecer el desarrollo normal y el cuidado de sus hijos en las actividades de la vida cotidiana. Señalamos aspectos del desarrollo susceptibles de ser observados regularmente y sobre los que se puede incidir mediante recomendaciones que modulen la relación con el niño. Exponemos una visión clínica del desarrollo infantil que permita, de manera sencilla, resolver las necesidades de los padres sobre cómo supervisar y conducir el desarrollo de sus hijos. Les proponemos complementar su evaluación con indicaciones y sugerencias para que aprendan a observar a sus hijos, siguiendo determinadas secuencias que de no cumplirse indican al pediatra una condición de riesgo y la necesidad de aplicar una prueba de tamizado completa otra de mayor especialización en la que se tenga experiencia.

Authors: Nascimento A. P. S. , Pinto A. L. , Duarte M. E. M. , Sousa F. C. , Araújo A. dos S.
Published: November 2016

Os taninos são compostos naturais que têm a propriedade de complexarem com as proteínas formando agregados insolúveis em solução. A interação destes compostos com as proteínas salivares leva à sensação de adstringência de alguns frutos (especialmente se pouco maduros) e bebidas como o vinho tinto e o chá. No presente estudo pretende-se verificar de que forma a concentração de protéina e tanino, as suas estruturas, hidratos de carbono e ainda a  força iónica, podem influênciar a formação de complexos tanino-proteina. Verificou-se que menores concentrações de proteína no meio vão provocar um aumento da adstringência. A estrutura da proteína também irá influência a formação de complexos tanino-proteína, o aumento da força iónica irá provocar uma diminuição da formação de complexos tanino-proteína, hidratos de carbono com uma estrutura não capsolante em elevadas concentrações irão provocar uma aumento da adstringência, ao contrário de hidratos de carbono com uma estrutura capsolante.

Influence of protein concentration, ionic strength and type of carbon hydrate in training complex tannin-protein

Abstract: The tannins are natural compounds which have the property of complexing with proteins form insoluble aggregates in solution. The interaction of these compounds with salivary proteins leads to the sensation of astringency of some fruits (especially if unripe) and drinks such as red wine and tea. The present study intends to check how the concentration of protein and tannin, their structures, carbohydrate and ionic strength also may influence the formation of tannin-protein complexes. It was found that lower protein concentrations in the medium will cause an increase in astringency. The protein structure will also influence the formation of tannin-protein complexes. Increasing the ionic strength will cause a reduction in the formation of tannin-protein complexes. Carbohydrates with a structure not capsolante in high concentrations will cause an increase in astringency, unlike carbohydrates with a capsolante structure.

Published: November 2016

This study reviews ten water utilities in Florida utilizing current pricing models to determine how municipal utilities approach affordability.  Water is no longer a commodity that can be taken for granted as the effects on the family budget has risen considerably in the past couple of decades. Increasing costs in capital, debt, personnel, chemicals, retrieval, and production have dramatically increased the price of water.  Municipalities are faced with diminishing resources, escalating costs, and the need to consider those less fortunate when determining utility pricing.  This research reviews programs available to utilities to offset the effect on capital requirements if municipalities adapt a low income friendly pricing model.  Ten Florida municipalities are examined utilizing data from the 2012 Water and Wastewater Rate Study conducted for the American Water Works Association.   Additionally, affordability programs for all ten municipalities are reviewed.

Published: November 2016

Teknologi telekomunikasi terus berkembang seiring dengan perkembangan jaman. Mulai dari komunikasi kabel hingga komunikasi nirkabel. Salah satu pemanfaatan komunikasi nirkabel sebagai media komunikasi adalah teknologi radio yang diterapkan pada salah satu peralatan navigasi penerbangan, yang dikenal dengan istilah Doppler Very high Omni-Directional Range (DVOR). Dalam DVOR, informasi yang dikirim menggunakan efek doppler menuju pesawat akan  mengalami penurunan sinyal (loss) yang diakibatkan oleh jarak. Dengan melakukan analisis perhitungan link budget menggunakan parameter pathloss dan atenuasi terhadap efek doppler dengan objek penerima (pesawat), maka apabila pesawat semakin mendekat, akan menghasilkan perubahan nilai pathloss dan atenuasi yang tidak berarti. Perhitungan pathloss dengan peubah jarak menghasilkan pengurangan ± 1dB pada rentang jarak tempuh pesawat, mulai dari jarak 30 Km hingga 5 Km dengan interval 5 Km. Sehingga semakin jauh jarak yang ditempuh oleh gelombang frekuensi Fobserved maka semakin besar nilai atenuasi yang akan diterima. Pada analisis atenuasi sebuah antena terhadap jangka waktu tertentu menghasilkan perubahan sebesar ± 1dB dalam waktu tempuh dengan rentang masing-masing sebesar 32 detik, 29 detik, 26 detik, 22 detik, 18 detik, 15 detik, 12 detik, 10 detik, dan 8 detik, dan diperoleh kesimpulan semakin besar nilai waktu yang dipergunakan pada sebuah antena DVOR maka semakin kecil atenuasinya.

Published: November 2016

VLAN (Virtual LAN) merupakan sebuah teknologi yang dapat mengkonfigurasi jaringan logis independen dari struktur jaringan fisik. Hasil dari penelitian sebelumnya sudah diprediksi bahwa dibutuhkan Virtual Network yang akhirnya terciptalah VLAN. Namun paradigma jaringan saat ini tidak flexible, ketergantungan terhadap vendor sangat besar karena fungsi data plane dan control plane berada dalam satu paket device. SDN (Software defined network) yang merupakan salahsatu evolusi teknologi jaringan sesuai dengan tuntutan yang berkembang dimana memisahkan fungsi data plane dan control plane pada suatu perangkat. POX Controller digunakan untuk men-simulasikan dan menguji Platform SDN (Software defined network). Pada penelitian ini menggunakan Openflow versi 1.0 untuk memasang header VLAN sehingga penelitian ini difokuskan untuk mengevaluasi performa forwarding VLAN yang memanfaatkan Openflow sebagai control plane dapat berfungsi dengan baik. Hasil penelitian ini mengusulkan penerapan karakteristik teknologi VLAN pada SDN karena telah berjalan dengan benar sesuai hasil pengujian konektifitas, verifikasi dan keamanan. Kemudian hasil pengujian lanjutan untuk melihat pengaruh SDN dengan skenario penambahan jumlah VLAN ID didapatkan bahwa set-up time akan bertambah seiring meningkatnya jumlah host dan dengan menggunakan protokol OpenFlow, latency yang terjadi di jaringan dapat dipantau dengan parameter round trip time (RTT) yang stabil direntang 0,2 sampai 6 second walaupun jumlah vlan_id dan background traffic bertambah.

The article objective is to review theoretical and methodological problems of the library collection formation in accordance with national standards (GOST R 7.0.93-2015) requirements: optimization of technological processes for acquisition, registration, organization of library collections through the use of modern technologies, to upgrade the terms system relating to holdings. The work set and solved the following tasks: defining the library collection object; correlating notions of «the Russian Federation library fund» and «the national library fund»; analyzing the library collections grouping by a functional purpose; considering its modeling, basic principles of acquisition, distribution features; pointing reasons to exclude documents of the library collection; showing indicators to characterize the library holdings state. The library collection formation is considered as a series of successive processes and operations aimed to transform the documents amount in an orderly and systematic set (library fund). For the first time funds of a separate library are divided by functionality: custom funds designed specifically to serve users; technological funds used to maintain the user collections functioning, which are not included directly in library and information services. Stocks allocation is referred to activities on spatial ordering of documents in specially equipped premises - depositories, servers and/or other storages. Allocation of a local network of electronic documents is carried on servers and/or other electronic library repositories and organized by software and hardware. A detailed analysis of such complex library actions as documents exception, redistribution, and exclusion of the library fund is given
When does the librarianship became a science in Russia?
Authors: Vaneev A. N.
Published: November 2016

The main article objective is a terminological analysis of «librarianship» concept. The development of theoretical concepts of librarianship as a science and as a branch of knowledge is explored. The concept of «library thought» and its correspondence with the concept of «the history of librarianship» is analyzed. The author substantiate the idea that the library thought development did not contradict the history of library science and was its important part, librarianship roots should be traced with the emergence of the first libraries. This point of view on the history of librarianship found understanding in the works by I. V. Lukashov, V. V. Skvortsov, M. I. Slukhovsky, Yu. N. Stolyarov and other library scholars. The article deals with polemic questions: when has librarianship been recognized as a science; can the first use of the concept of «librarianship» be considered as a sign of the emergence of library science. The analysis of applying the concept «library science» showed that before the early XX century it was defined as «a systematic presentation of knowledge about libraries organization and the management». The article analyzes dividing the library science into theoretical and practical parts; examines the fate of the theoretical librarianship in frames of «theoretical» discussions taken place in early 1930s, and attempts of Soviet scientists (V. A. Artisevich, I. A. Mesenyashin, N. Ya. Fridieva) to revive the theoretical library science; considers the views of Yu. V. Grigoriev substantiated the library science as independent one. Analysis of the national library science thought development in 1960s-70s of the XX century showed that its development was characterized by a scientific approach, with heightened attention to general theoretical and methodological problems that contributed to forming the librarianship as a science. The article states that in the modern terminology of the national library science there are two concepts: as a librarianship independent science and as a branch of knowledge. Combination into a single term of at least two different «library sciences» leads both to typological and substantial inconsistencies and errors, which can be seen in a variety of theoretical and practical disciplines including the word «librarianship». The author offers two options concerning use of the term «librarianship». The first one is to call the «librarianship» on the western model «library science», and the term «librarianship» applies to various disciplines (library science as a branch of knowledge). The second one is to retain in national science traditional name «librarianship» as a synonym for «library science» and not to use the word «librarianship» in the titles of different library disciplines to avoid confusion.

Reducing maternal and child mortality is the most important goal of the National Rural Health Mission. Indian government has worked towards its commitment to achieve the Millennium Development Goals.  Huge investments are being made by Government of India to achieve these goals. A well framed roadmap is being developed for accelerating child survival and improving maternal health and 16 indicators is selected for this purpose. The improvement in these indicators shows the way towards the achievement of MDGs.  India has made considerable progress over the last few years since NRHM in the area of maternal and child health, which was further accelerated after introduction of RMNCHA+ () strategy which appropriately directs the states to focus their efforts on the most vulnerable and disadvantaged sections of the society in the country. Main focus is healthy mothers and child. It also emphasizes on the need to reinforce efforts in those poor performing districts that have already been identified as the high focus districts. ‘Continuum care’ is required to have equal focus on various life stages.  Improvement in these indicators provide an understanding the importance of ‘continuum of care’ to ensure equal focus on various life stages. Some low performing districts had shown an improvement over period of time in its RMNCHA+ indicators.

Companies that implement information technology should have the ability to manage the governance and the implementation of the Information Technology Governance (ITG). Application of IT Governance may support the organization in building a framework to direct and decide the utilization of IT according to the organization needs aligned with its vision, mission, values, strategy, and culture. Keputusan Minister of BUMN is the reference on good IT governance through its implementations in state-owned enterprises. According to the IT governance framework mentioned in PER-02/MBU/ 2013, COBIT 4.1 is a framework that focuses on the relationship between IT and enterprise business. Hence, in this research, COBIT (Control Objective for Information and Related Technology) 4.1 framework is used to analyze and design the IT governance. In the first phase, the maturity level is measured to analyze the maturity and gap level of the IT governance in PT. XYZ, i.e. using Plan and Organise (PO) and Acquire and Implement (AI) domains. In the next phase, the priority analysis is conducted. The result of the analysis is considered as essential and critical process take the next analysis, i.e. gap and risk analysis. Afterwards, the IT governance map is designed. The design includes policy, procedure, organization structure, technology recommendation, and processes priority related document template.

IT Consultants are in the need of knowledge resources from experts who have either tacit, implicit, or explicit. Hence, a system that is able to manage knowledge (Knowledge Management/KM) is required. Along with success stories and failure experienced by many organizations in the implementation of KM system, it indicates that there should be factors that have roles in determining the successes of KM implementation. These factors are highly related to the readiness of the institution or company. Therefore, before implementing KM, it is necessary to analyze the readiness of the institution or organization. Analysis of readiness is expected to give an overview to the management about the state of readiness and aspects related to the successful implementation of KM. This study aims to measure the readiness of KM implementation in IT division in one of the IT consultation firm. The measurement of readiness was based on the extraction results of previous studies from which seven research aspects are obtained to be analyzed. Those aspects are strategy, organization, culture, technology, motivation, process, and human resources. Data was collected by questionnaires while data analysis was performed using descriptive statistical analysis. The analysis showed that the overall implementation of KM in IT division reached a readiness level of 2.26 in implementing KM.
Uncertainty analysis and prediction of river runoff with multi-time scales

Published: November 2016

Increasing water-issues demand that water resources managers know and predict the uncertain characteristics of river runoff well. In this paper, the fluctuating periods and local features of runoff with multi-time scales are analyzed by the empirical mode decomposition method. With the set pair analysis method, the uncertainty properties of runoff series with different multi-time scales are expressed. Meanwhile, cointegration theory is introduced to indicate the long-term equilibrium relationships between runoff series, and then the runoff prediction model is proposed based on the error correction model (ECM). The results show that the runoff series of Heihe River in northwest China exhibit complex relations with different periodic fluctuations and changing laws. The identity degree is the main relation between two runoff series, especially in the short period. Both the original series and decomposed components are all cointegrated, and the established runoff prediction model based on the ECM can simulate and predict river runoff well.

Aim. The study was designed to compare the immediate echocardiographic characteristics of aortic valve reconstruction by using autologous pericardium and the method proposed in 2007 by Shigeyuki Ozaki, as well as aortic valve replacement by means of frame-mounted biological prostheses Medtronic HANCOCK®II T505 CINCH® II and the Carpentier-Edwards PERIMOUNT.
Methods. Over a period from January 2014 to February 2016, 76 patients underwent aortic valve replacement by means of frame-mounted biological prostheses Medtronic HANCOCK®II T505 CINCH® II (n=41) and Carpentier-Edwards PERIMOUNT (n=35) at our hospital. 20 patients underwent the Ozaki procedure. These three groups of patients were assigned to the study. Demographic and preoperative indicators of patients from all three groups were homogeneous (р>0.05). The evaluation of the aortic valves replaced was carried out by echocardiography.
Results. Echocardiography was performed before the procedure and in the early postoperative period. Statistical analysis using ANOVA showed significantly lower values of the aortic valve pressure gradient (p<0.001) and larger effective orifice area and indexed effective orifice area of the valve (p<0.001) in the group of the Ozaki procedure.
Conclusion. According to echocardiography data, in the immediate postoperative period the Ozaki procedure is associated with lower mean and peak gradients of pressure on the aortic valve and larger effective orifice area and indexed effective orifice area of the valve, as compared with the frame-mounted biological aortic prostheses Medtronic HANCOCK®II T505 CINCH® II and the Carpentier-Edwards PERIMOUNT.
