A tudásreprezentáció és a tudásmegosztás információtechnológiai megoldásai a személyazonosság-menedzsment területén (Knowledge Representation and Sharing for Identity Management Domain)
Authors: Kő Andrea
Published: August 2021

A személyazonosság-menedzsment napjaink fontos kutatási területe mind elméleti, mind gyakorlati szempontból. A szakterületen megvalósuló együttműködés, elektronikus tudásáramoltatás és csere hosszú távon csak úgy képzelhető el, hogy az azonos módon történő értelmezést automatikus eszközök támogatják. A szerző cikkében azokat a kutatási tevékenységeket foglalja össze, amelyeket - felhasználva a tudásmenedzsment, a mesterséges intelligencia és az információtechnológia eszközeit - a személyazonosság-menedzsment terület fogalmi leképezésére, leírására használt fel. Kutatási célja olyan közös fogalmi bázis kialakítása volt személyazonosság-menedzsment területre, amely lehetővé teszi az őt körülvevő multidimenzionális környezet kezelését. A kutatás kapcsolódik a GUIDE kutatási projekthez is, amelynek a szerző résztvevője. ______________ Identity management is an important research field from theoretical and practical aspects as well. The task itself is not new, identification and authentication was necessary always in public administration and business life. Information Society offers new services for citizens, which dramatically change the way of administration and results additional risks and opportunities. The goal of the demonstrated research was to formulate a common basis for the identity management domain in order to support the management of the surrounding multidimensional environment. There is a need for capturing, mapping, processing knowledge concerning identity management in order to support reusability, interoperability; to help common sharing and understanding the domain and to avoid inconsistency. The paper summarizes research activities for the identification, conceptualisation and representation of domain knowledge related to identity management, using the results of knowledge management, artificial intelligence and information technology. I utilized the experiences of Guide project, in which I participate. The paper demonstrates, that domain ontologies could offer a proper solution for identity management domain conceptualisation.
Binomios en la enseñanza musical
Authors: Zilli Lía , Ferrero Emanuel
Published: August 2021

En el presente artículo reflexionaremos en torno a los relatos de tres docentes de música que actualmente se desempeñan en institutos de formación de docentes (IFD) en la ciudad de Santa Fe.

Recuperaremos parte de lo dicho en tres binomios: Escuchar-Disfrutar, Arriesgar-Desarmar y Convivir-Vincular; que permitan acercarnos a la complejidad y heterogeneidad que caracterizan a las prácticas de Educación Musical (en el Nivel Superior en general y en los IFD en particular). A partir de ese acercamiento, articularemos algunas posibilidades para pensar el lugar del placer y del disfrute en su vínculo con la escucha, el riesgo como espacio de oportunidad para la transformación de prácticas docentes y el desafío de irrumpir en la enseñanza de la música desde un abordaje vincular y humano en sintonía con el convivir.
Recorrido histórico de la guitarra jazz en Santa Fe
Authors: Castellano Oscar
Published: August 2021

A lo largo de más de 30 años la ciudad de Santa Fe (Arg.) ha desarrollado una fuerte actividad artística dentro del género del jazz. Cuenta con importantes festivales dónde el jazz ocupa un rol protagónico, como son El Festival de Jazz de Santa Fe, Trombonanza y también el Festival internacional de Percusión. Estos eventos han traído grandes figuras del género como Paquito D' Rivera, Conrad Herwig, Jeff Gardner, Ernesto Jodos, “Fats” Fernández, Remiggio Pereyra Pintos, entre otros.

Dentro de este panorama la guitarra de jazz fue acompañando el proceso evolutivo del género en la ciudad. En su recorrido diversos guitarristas realizaron importantes aportes para la comunidad santafesina del jazz y compartieron sus aprendizajes con nuevos interesados en el instrumento. Así se fue formando un árbol genealógico donde los años comenzaron a manifestar diferentes generaciones de guitarristas.

Éstas generaciones, sus principales actores, la relación entre ellos y sus influencias mutuas, sus historias de vida y su aporte para el circuito de jazz de Santa Fe entre los años 1955 a 2005 serán las temáticas de este artículo.
Historia de las mujeres, género y musicología:
Authors: Mariani Tomás Agustín
Published: August 2021

En la primera parte de este artículo presentamos algunos hitos importantes del devenir de la historia de las mujeres en la historiografía tomando como eje a la categoría de género. Nos detenemos en los casos de Estados Unidos, apoyándonos en la perspectiva de Joan Scott (2003), y de Argentina, apoyándonos en la perspectiva de Dora Barrancos (2005). Posteriormente, articulamos la categoría de género con el devenir de la historia de las mujeres en el ámbito de la musicología. 

En la segunda parte de este artículo presentamos un análisis del disco mujer/MUJER (1984) de Chany Suárez retomando herramientas presentadas en la primera parte.

Este trabajo se inscribe dentro de una investigación más amplia, que abarca referentes emergentes del folklore argentino entre el fin de la dictadura (1982-1983) y el comienzo de la democracia. En ese sentido, nuestra propuesta de análisis considera a este disco como un dispositivo de enunciación, en línea con nuestros anteriores trabajos (Mariani, 2019a; 2019b y 2020).
Canon y educación musical
Authors: Beltramino Fabián
Published: August 2021

Este artículo sintetiza los resultados de dos investigaciones acerca del canon musical: una dedicada al relevamiento de la programación de conciertos, la otra al de la oferta académica de la formación musical. Se establece, así, una correlación entre el canon que surge de la performance y aquél que surge de la instancia formativa de aquellos que ejercen la práctica. El trabajo efectuado permite concluir que por más “abierta” que se plantee la dimensión conceptual, en la práctica, los contenidos de una educación musical basada en lo modélico y en el paradigma de lo consagrado y lo ejemplar están más que vigentes.

En cuanto a la pregunta acerca de si el repertorio es consecuencia de la formación del músico o es un factor que orienta esa formación, se propone una tercera posición, la alternativa especular, que implica aceptar que ambas dimensiones se encuentran atrapadas en una relación circular respecto de la cual resulta muy difícil pensar alguna clase de desvío.
Libertad formal frente a libertad posesiva y libertad comunal: los tres conceptos de la libertad de Isaiah Berlin.
Authors: Schwartz Girón Pedro
Published: August 2021

Este trabajo pretende aclarar y defender la distinción entre “libertad negativa”, por un lado, y “libertad positiva” y “libertad comunal”, por otro, presentada por Isaiah Berlin. Esa distinción ha sido atacada por quienes consideran que no es acorde con la igualdad o con la fraternidad, virtudes que muchos autores progresistas colocan en el mismo plano que la libertad.   En lugar de la denominación de “libertad negativa” propuesta por Berlin, se propone la de “libertad clásica o formal”. A su vez, en lugar de la denominación de libertad “positiva”, se proponen los términos de “libertad posesiva” y la “libertad comunal”.   Así pues, Isaiah Berlin debería haber hablado de tres conceptos de libertad y haber destacado que los dos últimos tienen un efecto destructivo del primero.   Las libertades posesiva y grupal pueden ser aspectos apreciables de una sociedad, pero no deben confundirse con la libertad personal. El fomento de las libertades posesiva y comunal viene muchas veces acompañado de invasiones de la libertad formal.
Un buen medio para un buen fin: una visión utilitarista de la democracia.
Authors: Rodríguez López Blanca
Published: August 2021

La conexión entre utilitarismo y democracia siempre ha sido estrecha, hasta el punto de que algunos autores consideran que la democracia no es sino el utilitarismo aplicado a  la política. Este punto de vista es discutible, pero sin duda los principales utilitaristas han  sido defensores de la democracia, si bien sus propuestas prácticas han sido distintas, así como  también lo han sido los argumentos presentados para su defensa. En este trabajo analizamos las  principales causas de esas variaciones: las diferencias existentes en las propias propuestas  utilitaristas de los distintos autores y la diversidad de las circunstancias históricas y políticas  en que las mismas se presentaron.

Published: August 2021

An innovative experimental protocol is presented, linking a nondestructive (on computed tomography scanner) and destructive approach (bending test on electrostatic press). This study aimed to evaluate the annual growth ring’s impact on the mechanical behavior of wood. The tests were carried out on temperate specimens (Pseudotsuga menziesii and Abies alba Mill) from the Massif Central Region of France and tropical specimens (Aucoumea klaineana Pierre, Milicia excelsa, and Pterocarpus soyauxii) from Gabon. The connection between the mechanical parameters, taken from these tests and their structural characteristics, are also highlighted. Based on these results, a database was formed of the annual growth ring’s impact on the mechanical characteristics of these species. A link was found between the annual growth ring and the mechanical and physical characteristics of the species. The number and width of the earlywood ring and its mechanical properties were also investigated for each type of species. This comparison and the link highlighted was possible due to the study of the impact of dry density’s specimens, considered in this work as an adjustment parameter on the study of the mechanical behavior of these species.

Authors: AVCI Şebnem , KURUL Ramazan , ÇANKAYA Hatice , SEVİM Serkan
Published: August 2021

Purpose: Stroke; causing sensory, perception, motor loss, affects balance, postural stability and mobility. Position sense of trunk and its stability are important in terms of limb functions. Various methods are used in physiotherapy and rehabilitation, including orthotic devices to increase trunk control. This study aimed to investigate the immediate effect of elastic trunk orthosis on trunk repositioning sense and balance in post-stroke individuals.Methods: A total of 56, 28 with stroke and 28 age matched healthy individuals, were included into study. Repositioning sense and balance were evaluated with and without a trunk orthosis, using the HUMAC NORM isokinetic device, Trunk Impairment Scale, Postural Assessment Scale for Stroke Patients, and Functional Reach Tests.Results: There was no significant difference within and between groups on trunk repositioning sense with and without corset use (p˃0.05). Postural Assessment Scale for Stroke Patients scores did not show significant change (p˃0.05). There was a significant difference in favour of corset use in both study and control groups in functional reach test (p=0.013 and p<0.001 respectively). Study group showed significant change with and without corset scores in Trunk Impairment Scale (p=0.003). Mean differences on Functional Reach Test and Trunk Repositioning Test showed no significant difference in both groups (p˃0.05).Conclusion: The use of trunk orthosis has an immediate effect in some functional tests, but not in terms of repositioning sense were concluded. We propose to examine the factors affecting the repositioning sense in individuals with stroke and to investigate the effectiveness of new physiotherapy applications accordingly.

Análisis multianual de parámetros poblacionales del chigüiro (Hydrochoerus hydrochaeris) en las sabanas inundables colombianas, con miras a su aprovechamiento
Authors: Tiboche García Arlensiu , López Arévalo Hugo Fernando
Published: August 2021

El uso sostenible de la vida silvestre requiere información sobre los parámetros demográficos de poblaciones. Si bien, el uso del chigüiro se da en toda su distribución, en Colombia el aprovechamiento legal está suspendido hace dos décadas. Las sabanas inundables de Colombia y Venezuela albergan las mayores poblaciones de chigüiro y se encuentran en riesgo debido a transformaciones antrópicas. Estimamos densidad, tamaño poblacional, estructura de edad y tamaño de grupo de una población de chigüiro. Presentamos información de siete muestreos entre el 2004 y 2017 en una cuadrícula de 3600 ha con transectos espaciados 700 m en Paz de Ariporo, Casanare (Colombia). Se realizaron tres tipos de comparaciones: 1) Períodos climáticos interanuales, iguales en muestras de años contiguos, 2) Períodos climáticos estacionales, diferentes de años contiguos, y 3) por década, períodos climáticos iguales en intervalos de una década. Para todos los muestreos calculamos la tasa de crecimiento poblacional finito (λ) y el índice de producción máxima (Pmax); para los muestreos coincidentes con la cosecha legal en Colombia calculamos el índice de cosecha sostenida (h). En 2005, la población presentó el mayor tamaño (N = 12 802, D = 3,75ind / ha), mientras que en 2017 disminuyó (N = 6 928, D = 2,03ind / ha). En las comparaciones estacionales λ muestra una disminución cercana al 30 %, mientras que, por década, hay fluctuaciones positivas y negativas. Para 2005 y 2015, (h), indica que el aprovechamiento sustentable es viable, sin embargo, es necesario el monitoreo de las poblaciones y su hábitat.
Coma mixedematoso como causa asociada a falla cardíaca de etiología múltiple. Reporte de caso
Authors: Rodriguez Pantoja David Alejandro , Morcillo Muñoz Jorge Alfredo
Published: August 2021

Introducción. El coma mixedematoso representa la máxima y más rara expresión del hipotiroidismo en los adultos. Esta complicación es más frecuente en mujeres ancianas y tiene diversas formas clínicas asociadas como enfermedades con compromiso sistémico, entre ellas la falla cardíaca, el tromboembolismo pulmonar y la fibrilación auricular en pacientes inestables.
Presentación del caso. Paciente femenina de 73 años con antecedentes de insuficiencia cardíaca, hipertensión arterial y sobrepeso, quien presentó deterioro funcional, disnea en reposo, taquipnea, taquicardia, desaturación, edemas generalizados, cianosis distal e ingurgitación yugular. Los exámenes paraclínicos mostraron anemia leve, glucemia y electrolitos normales, azoados con deterioro de la función renal, TSH: 100 µUI/mL, T4 libre: 0.21 ng/dL, ritmo de fibrilación auricular con respuesta ventricular rápida e hiperlactatemia. A partir de los hallazgos se diagnosticó falla cardíaca asociada a coma mixedematoso de novo, que requirió soporte inotrópico y vasopresor, y tromboembolismo pulmonar asociado a signos de disfunción sistólica derecha. Finalmente, la paciente tuvo evolución lenta hacia la mejoría con la suplencia hormonal, optimización de falla cardíaca y anticoagulación.
Conclusión. El coma mixedematoso es una forma extrema e infrecuente de hipotiroidismo que se asocia con altos niveles de morbimortalidad dado que implica manifestaciones sistémicas graves. El diagnóstico oportuno y la implementación temprana de un tratamiento de soporte y específico, sobre todo con suplencia agresiva de hormonas tiroideas y vigilancia en unidad de cuidados intensivos, ayudan a mejorar el pronóstico de los pacientes con esta complicación.

Se evaluó la actividad antifúngica del aceite esencial de limón de cerca (Swinglea glutinosa) sobre el hongo Colletotrichum sp. aislado de frutos de mango (Mangifera indica L). El aceite esencial, se obtuvo por hidrodestilación de hojas y corteza del fruto, y mediante cromatografía de gases acoplada a espectrometría de masas se determinó la fitoquímica. Se identificaron presuntivamente 41 metabolitos secundarios, siendo los compuestos mayoritarios β–pineno (31.3 %), α–pineno (15.1%) y germacreno D (14.4 %). El aceite esencial inhibió el crecimiento del hongo en un 31.16 %, 52.77 % y 82.41 % en ensayo de dilución en agar, a las concentraciones de 0.3, 1 y 2 % respectivamente, con diferencias entre todos los tratamientos evaluados (p=0.000). En ensayo de dilución en caldo se registró inhibición de la germinación de esporas de 0, 19.47, 41.03 y 100 % (p=0.000) a concentraciones de 0, 2, 4 y 8 µL/mL. Adicionalmente, en ensayo de microatmósfera se presentó una inhibición de máxima de 22,97 % del crecimiento micelial con adición de 20 µL de aceite esencial por caja de Petri (p=0.000). Este trabajo encontró que el aceite esencial de S. glutinosa ejerce inhibición dosis-dependiente sobre el crecimiento micelial y la germinación de esporas de Colletotrichum sp.

Published: August 2021

En las últimas décadas se ha trabajado activamente para reducir el impacto ambiental generado por las actividades antrópicas que constantemente liberan componentes tóxicos al ambiente generando inestabilidad y daños en la salud de las comunidades biológicas. Entre los diferentes contaminantes, los metales pesados revisten importancia en virtud de sus propiedades, que dificultan su degradación o transformación en otros compuestos menos tóxicos. El cromo es uno de los metales de mayor interés a nivel global por su uso en múltiples industrias. Los métodos convencionales que utilizan materiales cromados en sus procesos, no sólo arrojan cantidades considerables de residuos al ambiente, sino que dan poca cuenta de la fracción de Cr6+ presente en determinados ecosistemas. La biorremediación se ha propuesto como una alternativa económicamente viable y ambientalmente sostenible. El propósito del presente trabajo fue evaluar la capacidad de reducción de cromo por bacterias, aisladas de una matriz de biosólidos de la Planta de tratamiento de aguas residuales (PTAR) San Fernando en la ciudad de Medellín-Colombia. Muestras de biosólidos se cultivaron en Agar Nutritivo enriquecido con diferentes concentraciones de Cr6+. Las cepas que presentaron mayor tolerancia al cromo fueron aisladas para realizar ensayos de reducción por triplicado, monitoreando la concentración del metal en el tiempo. Se obtuvieron siete especies bacterianas diferentes dentro de las cuales se destacaron Staphylococcus saprophyticus, Ochrobactrum anthropi y Bacillus cereus por la capacidad de reducir Cr6+ a 96 h con eficiencias de 29.0%, 61.1% y 100%,  respectivamente.
Analysis of the protein profile of the venoms of snakes Bothrops asper, Bothrocophias myersi and Crotalus durissus from the Colombian Andean Region obtained by RP-HPLC

Published: August 2021

Snake venoms comprise a highly complex mixture of proteins, and there is also a high interspecific and intraspecific variability in their composition, even in the same region. Our aim was to compare the composition of the venoms of Bothrocophias myersi, Crotalus durissus and Bothrops asper, snakes from the Andean region in Colombia by Reverse-Phase High-Performance Liquid Chromatography (RP-HPLC). The venoms were given to the research group under an agreement with the Fundación Zoológica de Cali. The venoms pool was obtained by manual extraction, lyophilized and refrigerated. The protein found in the venoms was quantified by spectrophotometry using the Bradford and Lowry methods and direct measurement by Nanodrop®. The protein composition was stablished by RP-HPLC, using a Lichosper 100 RP, C18 column (250X4 mm) with a pore size of 5µm, as well as by Sodium Dodecyl Sulfate-Polyacrylamide Gel Electrophoresis (SDS-PAGE). The highest quantity of protein was found in the venom of B. myersi (108,6 mg/mL) followed by C. durissus (78,1 mg/mL) and B. asper (74.1 mg/mL). All venoms showed bands of 15 and 50 KDa by SDS-PAGE; The most important finding is the abundance of PLA2 and svMP in the venom of B. myersi. Chromatographic analyses revealed a very similar venom composition profile, but also certain differences in toxins abundance. We conclude that the process of separating the venom proteins by RP-HPLC and SDS-PAGE are very important as a first step to know the venoms profiles, which in turn could allow medical staff to elucidate the clinical syndrome produced by snakebites.

Investigating chromium cycling in global oxygen deficient zones with chromium isotopes
Authors:   , Huang Tianyi
Published: August 2021

Chromium (Cr) isotopes have shown great potential as a paleo-redox proxy to trace the redox conditions of ancient oceans and atmosphere. However, its cycling in modern environments is poorly constrained. In my thesis, I attempt to fill in the gap of our understanding of chromium cycling in the modern ocean, with a focus on the redox processes in global oxygen deficient zones (ODZs). Firstly, we developed a method to analyze Cr isotopes of different Cr redox species. Tests on processing conditions demonstrated its robustness in obtaining accurate Cr isotope data. It is applicable to both frozen and fresh samples. This method allows us to investigate the redox cycling of Cr that is hard to unravel by existing total Cr methods. Secondly, in the Eastern Tropical North Pacific (ETNP), Eastern Tropical South Pacific (ETSP) and Arabian Sea ODZs, their total dissolved Cr profiles show preferential reduction of isotopically light Cr(VI) to Cr(III), which is scavenged and exported to deeper oceans. Applying our new method to ETNP and ETSP ODZ seawater samples, we observed Cr(VI) reduction in both ODZs with a similar fractionation factor. This indicates similar mechanisms may be controlling Cr(VI) reduction in the two ODZs. Cr(III) maximum coincides with Fe(II) and secondary nitrite maximums in the upper core of both ODZs. Shipboard incubations with spiked Fe(II) showed fast Cr(VI) reduction occurring in the ETNP ODZ. But neither Fe(II) nor microbes were reducing Cr(VI) directly. Thirdly, we calculated the isotope effects of Cr scavenging in the ETNP and ETSP ODZs. Thetwo ODZs show a similar isotope partitioning during Cr scavenging. And spatial variability is observed in the ETNP ODZ. Our calculated scavenged Cr isotope ratio is lighter than that of the total dissolved Cr from the same depth. It is also comparable to that of reducing or anoxic sediments, which implies that Cr isotopes can be used as an archive for local redox conditions.
LOS CENTROS DE DISTRIBUCIÓN EN PARQUES EMPRESARIALES MUNICIPALES Y EL OBJETIVO DE DESARROLLO SOSTENIBLE N°9
Authors: León Rincón Gonzalo Emilio , Higuita Cárdenas Camilo Alberto
Published: August 2021

El presente documento aborda la investigación del impacto que está causando el desplazamiento de los centros de distribución de empresas comerciales e industriales que funcionaban al interior de la ciudad de Medellín hacia parques empresariales logísticos, ubicados en las zonas rurales de municipios cercanos, y su incidencia, principalmente en el Objetivo de Desarrollo Sostenible N°9: Construir infraestructura flexible, promover la industrialización inclusiva y sostenible; y fomentar la innovación, en estos territorios. La metodología es de carácter cualitativo mediante un estudio de caso a dos empresas que se desplazaron hacia áreas rurales de municipios cercanos. Se encontró que, en los informes y planes de desarrollo, de los entes territoriales, ya están contemplados los ODS, sin embargo, no es clara la forma de lograr las metas propuestas o la forma de apalancamiento; adicionalmente, los indicadores regionales aún están en proceso de construcción. Por otro lado, la preparación logística y tecnológica de los municipios receptores de los centros de distribución aun es deficiente y, a diferencia de otras ubicaciones a nivel país, no están ofreciendo beneficios tributarios importantes a las empresas que decidan instalarse en los parques empresariales.

Published: August 2021

Bu araştırmanın amacı, Erzurum merkez ve çevre ilçelerinde Millî Eğitim Bakanlığına bağlı okullarda görev yapan öğretmenlerin memnuniyet düzeylerinin çeşitli değişkenlere göre incelenmesidir. Bu amaç doğrultusunda öğretmenlerin; görev yaptıkları ilçeye, okul türüne, hizmet yıllarına, cinsiyetlerine, eğitim durumlarına ve alanlarına göre memnuniyet düzeyleri arasında bir farklılık var mıdır?” soruları cevaplanmıştır. Nicel bir yaklaşımla tarama yöntemine göre yürütülen araştırmanın örneklemini, Erzurum merkez ve çevre ilçelerinde görev yapan 4.471 öğretmen oluşturmaktadır. Veri toplama aracı olarak araştırmacılar tarafından geliştirilen 60 madde ve beş alt boyuttan oluşan “Öğretmen Memnuniyeti Anketi” kullanılmıştır. Ankette elde edilen sonuçlara göre öğretmenlerin görev yapılan ilçe, okul türü, hizmet yılı, cinsiyet, eğitim durumu ve alanlarına göre memnuniyet düzeyleri arasında anlamlı farklılıklar olduğu belirlenmiştir. Araştırma sonuçlarından hareketle öğretmenlerin memnuniyet düzeylerinin düşük ve yüksek oluş nedenlerinin nitel çalışmalarla derinlemesine araştırılabileceği ve mesleğe yeni başlayan öğretmenlerin memnuniyet düzeylerinin düşük olma nedenlerinin farklı araştırmalarda ele alınabileceği önerilerinde bulunulmuştur.

The transition of a country's graduates with vocational skills into the labor market indicates both the efficiency of vocational education and training (VET) and economic development. Many countries have conducted studies to monitor and match the expectations of the labor market with students’ preferences. Scholars and policymakers in Turkey have long debated the compatibility of the level of VET graduates’ skills and needs of the labor market and called for field studies to form a basis for national policy. The current study examine the relationship between open job positions in diverse professions, as indicated by İŞKUR's 2019 Labor Market Research (IPA), and the vocational fields of VET students at the regional level. The skills required by the open positions and the vocational fields in which these skills were acquired are linked in this study to evaluate their compatibility. The research findings showed remarkable differences between the demands of the labor market and the supply of VET graduates across Turkey. In some vocational fields, the imbalance occurred simultaneously across multiple regions. The results emphasize the importance of improving the balance between supply-and-demand at both the regional and provincial level to increase the compatibility between labor market demands and supply in VET.

The purpose of this study was to determine middle school students’ national belonging levels in terms of different variables. In this quantitative study, middle school students’ views on national belonging were determined by the “National Belonging Scale for Middle School Students”. The study was conducted with 1318 middle school students in Niğde province of Turkey during the Spring term of the 2019-2020 academic year. Research data were collected through “National Belonging Scale for Middle School Students” and were analysed with SPSS 24 software package. According to the study results, middle school students had a high positive view of their national belonging. Their gender did not make a statistical difference in terms of both reasons and results of their national belonging. On the other hand, students’ views on national belonging differed in terms of their grade level. Again, although there was no difference between the public and private schools in terms of reasons of their national belonging, there was a statistically significant difference between them in terms of the results of their national belonging in favor of the public school. Another difference was determined between Turkish and refugee students’ national belonging. Turkish students’ mean scores of reasons and results of their national belonging were statistically higher than the refugee students’ mean scores. Considering national belonging in terms of each variable, middle school students’ national belonging can be strengthened with some activities that can be done within the scope of the implicit program as well as the educational activities carried out within the curriculum at schools. Social Studies is the most important course into which works on this subject can be integrated.

In this review of literature the authors provide information on the history of the development of treatment of patients with cystolithiasis with benign prostatic hyperplasia (prostate adenoma), as well as basic information regarding the most common and effective methods of treating this nosology. Cystolithiasis is one of the forms of manifestation of urolithiasis, characterized by the presence of stones in the bladder. Almost 70 % of this pathology occurs in patients with benign prostatic hyperplasia. Medical, economic and social significance is that the majority of patients from this group are of active, working age. Historical data show that this pathology has always been a serious problem requiring surgical intervention and often leading to the patient's disability. In turn, this pathology gave a serious impetus to the development of surgery and urology in particular. Only in the twentieth century it was possible to achieve a significant result in the treatment of this disease due to the improvement in the quality of nutrition, the beginning of the use of antibacterial therapy and the development of endourology.

Bladder extrophy - is a difficult malformation for the treatment. Aplasia of one of the cavernous bodies of the penis is an extremely rare pathology. In the available literature, we did not meet reports of correction of bladder extrophy in children with a single cavernous body of the penis.

From 1990 to 2020, 545 children (364 boys) with extrophy have been repair. Two (0.5 %) boys only had a classic bladder extrophy combined with the aplasia of one cavernous body. The first patient with classical extrophy and multiple malformations (fingers of the right hand, fingers of the right foot, aplasia of the left kidney, left cavernous body, left testicle and hypoplasia of the left half of the scrotum) the penis with the single cavernous body on the right was somewhat thinner, but formed anatomically correctly with the presence of a urethra and closed prepuce. The primary closure of the bladder was performed with bilateral iliac osteotomy and the joint of pelvic bones at the age of 1 year. The patient had the anatomically properly formed bladder sphincter and urethra, penile correction was not required. After the operation, urinary continence had been achieved.

The second boy was with classical extrophy and epispadia of the single cavernous body, he was given stage treatment. At the age of 5 days (2004) the primary closure of the bladder and the connection of the pelvic bones were performed. At the age of 4 years (2008) the formation of the urethra was carried out, the correction of the dorsal deformation of the single cavernous body by excision of the chord and the application of multiple superficial cross-cutting on the tunica albuginea. Bladder neck plastic by Kelly technique in combination with bilateral osteotomy of pelvic bones was performed at the age of 7 years in (2011). The boy of 15 years (2019) had a bladder volume of 350-400 ml. Dry 4-5 hours. Urinate freely with a wide stream. Then a two-stage plastic of the distal urethra was performed. We used the Bracka technique with augmentation of the glans penis and implantation a free graft of the mucous lip. We achieved a good result.

Using modern penile correction technologies help to socially adapt patients with rare and difficult malformations.

Unlike other typical clustering analysis, which considers column only, biclustering analysis processes a matrix into sub-matrices based on rows and columns simultaneously. One method of bicluster analysis uses the probabilistic model, like the plaid model, that provides overlapping bicluster. The plaid model calculates the value of an element given from a particular sub-matrix for each cell; thus, the value can be seen as the number of contributions of a particular bicluster. The algorithm begins with preparing the input data as a matrix, then an initial model is assessed and makes a residual matrix from the model. After that, we determine bicluster candidates, which are evaluated for its effect parameters and bicluster membership parameters. Finally, the bicluster candidate is pruned to give the optimal bicluster. We implemented the algorithm on gene expression dataset of colon cancer, where the rows and columns contain observations and types of genes, respectively. We carried out in six distinct scenarios in which each scenario uses different model parameters and threshold values. We measured the results using Jaccard index and coherence variance. Our experiments show that biclustering analysis on a model with mean, row, and column effects of colon cancer data output low coherence variance.

ABSTRAK. Penelitian bertujuan mempelajari pengaruh fermentasi secara aerobik dan anaerobik rumput gajah mini (RGM) sebagai pakan terhadap performan kambing Boerka. Penelitian dilaksanakan dalam Rancangan Acak Lengkap (RAL) dan terdiri atas tiga perlakuan yaitu RGM segar, RGM hasil fermentasi an-aerob dan RGM hasil fermentasi aerob. Pada setiap perlakuan ternak diberikan konsentrat dengan komposisi 50% hijauan dan 50% konsentrat berdasarkan bahan kering. Digunakan 24 ekor ternak kambing Boerka jantan (8 ekor per perlakuan). Ternak ditempatkan di kandang individu. Peubah yang diamati mencakup konsumsi bahan kering (BK), pertambahan bobot hidup harian (PBHH), efisiensi penggunaan pakan (EPP), income over feed cost (IOFC) dan kecernaan pakan. Hasil penelitian menunjukkan bahwa RGM segar sebagai pakan kambing dengan persentase pemberian 50% RGM dan 50% konsentrat menghasilkan PBHH dan IOFC yang nyata lebih tinggi (P0,05) dibanding RGM hasil fermentasi (62,1 vs 32,4 g/e/h dan Rp. 222.960 vs Rp. 104.397/e/3 bln) diikuti dengan EPP yang sama dengan RGM hasil fermentasi aerob sebesar 0,10. Pengolahan RGM melalui fermentasi meningkatkan kandungan protein kasar namun tidak meningkatkan kecernaan. Pemanfaatan RGM hasil fermentasi an-aerob untuk pakan kambing Boerka sedang tumbuh dapat menghasilkan konsumsi nutrien, kecernaan nutrien, PBHH, EPP dan IOFC yang sebanding dengan RGM tanpa fermentasi. (Aerob and un-aerob fermentation of dwarf elephant grass as feed for growing Boerka goat) ABSTRACT. The research was aimed to study the effects of fermentation of dwarf elephant grass (DEG) as feed on Boerka goat performances. The experiment was at Indonesian Goat Research Station, Sei Putih in 2015. The experiment was arranged in completely randomized designed, and consisted of three diet treatments namely 1) fresh (unfermented) DEG, 2) aerobically-fermented DEG, and 3) anaerobically-fermentation DEG. Goat was offered 50% concentrate and 50% DEG on every treatment based on dry matter. Twenty four of male Boerka goats were used on this experiment (eight animals per treatment). Parameters observed included dry matter intake (DMI), average daily gain (ADG), feed conversion ratio (FCR), income over feed cost (IOFC) and digestibility. The results showed that utilitazion of unfermented dwarf elephant resulted in higher ADG and IOFC (P0.05) than goats received aerob fermented dwarf elephant grass (62.1 vs 32.4 g/h/d dan Rp. 222,960 vs Rp. 104,397/h/3 month). Feed efficiency ranged from 0.08 to 0.10 and was not affected by treatments (P0.05). Fermentation of DEG increase crude protein content. The usage of anaerobically-fermentation DEG as feed of Boerka goat produce nutrient intake, nutrient digestibility, ADG, feed efficiency and IOFC which were comparable to DEG without fermentation.
