Authors: ASKERBEYLİ ÖRS Sevinc , AKSEL Hacer , KÜÇÜKKAYA EREN Selen , ZEYBEK Dilara
Published: July 2019

Background:To investigate the effects
of final irrigation protocols with tannic acid (TA) on dentin microhardness and
push-out bond strength of an epoxy resin based sealer to root canal dentin.Methods: The 50 root halves were embedded in an acrylic resin for the
microhardness measurement. After
the initial baseline microhardness measurement, the root halves were randomly
divided into 5 groups according to the final irrigation protocol used (n=10): distilled water (control), 10% TA for 2 min, 10% TA for 5 min, 20% TA for
2 min, and 20% TA for 5 min.
After surface treatment, dentin microhardness values were recorded at close
proximity to the initial indentation areas.

For push-out bond strength test the root canals of 75
single-rooted mandibular premolars were instrumented and the final irrigation protocols
were applied as described above (n = 15). Following
root canal obturation with single cone technique using matched-taper  gutta percha cones and
an
AH Plus- epoxy resin based root canal sealer, 1 mm-thick slices were obtained from the
middle third of the root canals. Push-out
bond strength test was applied. The data were analyzed using One way ANOVA and
Tukey HSD tests (p=0.05).Results:In TA-treated groups, there was a
significant increase in the microhardness values compared with the control
group (p<0.05). Regarding the push-out bond strength test, there was no significant
difference between the bond strength values of 10% TA for 2 min and the control
group (p>0.05). The remaining groups presented higher bond strength values
than the control group (p<0.05).Conclusions: TA increased dentin microhardness and the
bond strength of the epoxy resin based sealer to root canal dentin. The effect
on the bond strength was time and concentration dependent. Keywords: bond strength, dentin, microhardness, epoxy resin based sealer, tannic

MIGRACIONES CLIMÁTICAS: EL PAPEL DE LOS DERECHOS HUMANOS PARA SUPERAR EL PERSISTENTE VACÍO JURÍDICO
Authors: Pérez Beatriz Felipe , Iglesias Márquez Daniel , Villavicencio Calzadilla Paola
Published: July 2019

Los impactos del cambio climático afectan, directa e indirectamente, a los patrones de movilidad humana. De hecho, existen ya ejemplos de migraciones climáticas alrededor de todo el planeta. Las migraciones climáticas transfronterizas son especialmente relevantes, pues uno de los problemas más graves a los que se enfrentan las personas que huyen de sus países a causa del cambio climático, junto con otros motivos, es el escaso reconocimiento de su situación por el derecho internacional y, en consecuencia, la falta de protección jurídica. Ante este vacío, en el presente artículo se analiza la posible aplicación del derecho internacional de los derechos humanos, mediante dos formas, por un lado, como garantía básica de los derechos fundamentales de estas personas y, por otro, como fundamento para exigir la responsabilidad internacional de los Estados contaminantes, ante las violaciones de los derechos humanos que experimentan los migrantes climáticos.

EL ESTADO ACTUAL DEL CUMPLIMIENTO DE LAS MEDIDAS DE SATISFACCIÓN ORDENADAS POR LA CORTE INTERAMERICANA DE DERECHOS HUMANOS, EN LAS SENTENCIAS CONDENATORIAS CONTRA EL ESTADO COLOMBIANO
Authors: Martínez Espinosa Luisa Fernanda , Peláez Lozada Karen Vanessa
Published: July 2019

El propósito de este artículo es evaluar el estado actual del cumplimiento de las medidas de satisfacción ordenadas por la Corte Interamericana Derechos Humanos en las sentencias condenatorias contra el Estado colombiano, a partir de la revisión de las resoluciones de supervisión de cumplimiento. El SIDH consagra acciones judiciales en favor de las personas que han sido víctimas de violaciones de Derechos Humanos, no solo se busca la creación de instrumentos jurídicos para su protección, sino medidas que aseguren su cumplimiento y garanticen que lo ordenado no se convierta en un desafío, sino en una realidad persistente en el marco del Derecho Internacional de los Derechos Humanos. A través de un riguroso análisis jurisprudencial, doctrinal y estadístico se evalúa el grado de cumplimiento individual y global de todas las medidas de satisfacción ordenadas por la Corte Interamericana de Derechos Humanos contra el Estado colombiano: 1) reconocimiento de la responsabilidad internacional, 2) investigación de los hechos y las sanción de los responsables, 3) verdad, 4) búsqueda de personas desaparecidas y entrega de restos mortales, 5) publicación y difusión de las sentencias y las medidas educativas y de capacitación para víctimas, 6) creación de monumentos bustos y placas, 7) realización y difusión de audiovisuales documentales. Esta investigación jurídica con un nivel de profundidad evaluativo constituye un valioso aporte para los Derechos Humanos, al presentar un estudio pormenorizado de cada una de las medidas de satisfacción. Se concluye que el grado de cumplimiento de las medidas de satisfacción es del 48 % lo que genera una gran problemática, ya que el índice de incumplimiento tan solo es menor por un margen del 6 %, incluso existen medidas, donde su cumplimiento oscila entre el 0 % y el 8 %.

Authors: Bianco André Amaral Gonçalves
Published: July 2019

O consumo de bebidas alcoólicas notoriamente é relacionado a comorbidades, como: doenças gastrointestinais, hepáticas, cardiovasculares e infecciosas, condições neuropsiquiátricas e perinatais, cânceres e diabetes. Além disso, são amplamente divulgadas suas contribuições para incidência de acidentes automobilísticos. Entretanto, o valor calórico do etanol não alcança a mesma divulgação. O presente trabalho apresenta um estudo descritivo, não randomizado, realizado com 19 homens e 31 mulheres, com faixa etária de 17 a 35 anos, estudantes universitários do primeiro semestre do curso de Ciências – Licenciatura da Universidade Federal de São Paulo, campus Diadema. 88% desses estudantes apresentou desconhecimento do valor calórico do etanol e 72% desconhecem a contribuição calórica de uma dose de 200 mL de vodca. Esses resultados apontam para a necessidade da divulgação dessas características do etanol, sobretudo diante do quadro de sobrepeso e obesidade ao qual a população mundial está submetida.

Predictibilidad del mercado accionario colombiano
Authors: López-Gaviria José Ignacio
Published: July 2019

This paper studies historical stock market returns in Colombia and their medium- and long-term predictability with the purpose of examining whether there is a constant or time-varying risk premium and its relationship with other economic variables. With this goal in mind, the paper presents a historical price index, returns and the aggregate dividend yield of Colombia’s stock market for the 1995-2017 period, using information for the whole universe of issuers. Most of the variation in the dividend yield is explained by expected returns, which implies that the stock market has medium- and long-term cycles and the risk premium is time varying. The predictive power of the model increases if extended to include information on housing finance, the real exchange rate and returns of the S&P 500 index, suggesting that credit frictions and small open economy considerations could play a role when modelling risk premium in Colombia’s stock market.

Sources of Expanding of the Youth Jargon in Ukrainian at the Beginning of the XXI Century
Authors:   Borys Grinchenko Kyiv University, Styshov Oleksandr
Published: July 2019

The article focuses on one of the important layers of the lexical system of the national Ukrainian language at the beginning of the XXI century, namely the youth jargon neologisms. The recording of the spoken language of young people (schoolchildren, students of vocational schools, university students, cadets, etc.) as well as texts from the Internet and contemporary Ukrainian journalism and fiction served as the material of the present study. The body of newly formed slang words under analysis comprises more than 200 units. The author defines and analyses the main sources of the mentioned units’ enrichment. The most effective among them is the word formation on the basis of specific and borrowed derivative sources. It has been shown that within the analyzed period the youth jargon neologisms are mostly enriched by nouns-neologisms formed, in particular, by means of suffixation, univerbalization, abbreviation, compounding, lexico-semantic derivation or without any affixes at all. Newly formed adjectives, verbs and adverbs, being not numerous in comparison with nouns-sociolects of youth, are coined primarily by suffixation. Another effective source of the youth social dialect enrichment is their direct entry into Ukrainian from foreign languages, such as English, Russian, German, Spanish, French, and Chinese. Among these new borrowings English loan words prevail. Besides, a certain part of the youth neologisms has penetrated into speech of the young people from other jargons, such as computer, sports, automobile jargons. Some new units of the analyzed sociolect have come into use (mainly with a change in semantics) from a less effective source, i.e. a criminal argot
Digital Nomads and Settler Desires: Racial Fantasies of Silicon Valley Imperialism
Authors: McElroy Erin
Published: July 2019

This paper investigates the coloniality of contemporary digital nomadism, an identity that numerous Western tech workers use to describe lifestyles of location independence in which they travel the world while maintaining Silicon Valley salaries. Specifically, I assess colonial genealogies of digital nomads and more problematically defined “digital Gypsies.” It was during the height of 19th-century Western European imperialism that Romantic Orientalist texts proliferated, celebrating the racial and sexual “free and wandering Gypsy.” This deracinated figure was used to allegorize colonial desires and imperial violence alike. As I suggest, nomadic racial fantasy undergirds contemporary freedom desires today emergent from the heart of a new empire—that of Silicon Valley. In describing Silicon Valley imperialism and its posthuman digital avatar, I assess how nomadic fantasy transits technologies of gentrification into new frontiers. For instance, sharing economy platforms such as Airbnb celebrate the digital nomad, bolstering contexts of racial dispossession while continuing to deracinate Roma lifeworlds. Might nomad exotica in fact index coloniality and its ability to traverse time and space? How has this fantasy been abstracted over time, also entangling with posthumanist nomadic onto-epistemologies?
Subjective time scales when working with perspective human-computer interfaces
Authors: Turovskiy Y.A. , Mamaev A.V. , Alekseev A.V. , Borzunov S.V.
Published: July 2019

The analysis of subjective time scales of the subjects with perspective human-computer interfaces was carried out: neurocomputer (brain-computer), electromyographic, oculografic. It is shown that for all of them it is typical to underestimate the maximum time spent for the execution of one team. In this case, for the electromyographic and oculografic, this feature is also preserved for the indicators of the average time for executing the commands. The results of the assessment demonstrate a unified approach of users to the formation of subjective time when working with various interfaces: the user estimates both the averaged and the best (minimum) with the worst (maximum) time for executing commands on a single scale. Subjects who switched worse from generating one command for the interface to another subjectively rated the interface as slower. The HRV data showed the LF-band relationship with a subjective estimate of the time spent working with the interface. Analysis of the relationship (true time-subjective) / true time has shown that subjective time scales when working with the neurocomputer and oculographic interfaces demonstrate a high correlation with each other as opposed to electromyographic.
Opportunities and Problems of Analysis of Mortality from Myocardial Infarction According to Medical Certificates of Death (on the Example of the Tula Region)
Authors: Drapkina O. M. , Samorodskaya I. V. , Vaisman D. Sh.
Published: July 2019

Aim: to analyze the quality of completion medical certificates of death (MCD) of residents of the Tula region, in which in 2017 acute and subsequent myocardial infarction (MI) was listed as the underlying cause of death (UCD) or as multiple causes of death (MC).

Materials and methods. From the electronic database (DB) of MCD of residents of Tula region for 2017 we selected all MSD in which MI was written down irrespective of a section of MCD. A total of 689 MSD (43.8% men and 56.2% women) were analyzed.

Results. Mean age of the deceased was 72.6±11.3 years (men 67.25±0.62; women 76.7±9.8; p<0.001). Multimorbid pathology was registered in 31.5% of the deceased. In 77.9% of cases myocardial infarction was selected as the UCD and in 22.1% – as a complication of other diseases. Among registered MI complications were hemotamponade (24.5%), cardiogenic shock (3.6%), ventricular fibrillation (0.3%), heart failure (50.2%). Complications of MI were not listed in 3.9% of MCD. Analysis of MCD showed that their completion did not comply with established ICD-10 rules and recommendations of Ministry of Health of RF; all lines were filled out only in 1% of completed MCD. Also, problems of determining the initial cause of death when myocardial infarction occurred in the presence of multimorbid pathology were revealed.

Conclusion. Mortality analysis using solely UCD leads to decreasing mortality rates from MI, and unsatisfactory quality of filling the MCD decreases the ability to identify MC, that prevents the correction of priorities in the organization of medical care. The revealed problems of coding causes of death require urgent solutions from the professional community of cardiologists, pathologists, and the Ministry of Health.
Snow cover as a morphogenic agent determining ground climate, landforms and runoff in the Valdecebollas massif, Cantabrian Mountains
Authors: Pisabarro A.
Published: July 2019

Snowfalls are important meteorological events affecting the physical environment of the Cantabrian Mountains. This work analyzes the effects of snow on several elements such as relief, landforms, ground climate and snowmelt waters. The ground thermal regime and associated parameters were studied using temperature data loggers and satellite images and were described in combination with observed geomorphological processes and landforms. A geomorphological map was drawn up and trends in climate patterns and runoff were calculated. Ground temperature monitoring in warm years is not optimal, though allow to know the limit conditions for developing cold processes. Results show that geomorphological processes are not significant and that solifluction deriving from snowmelt, is the only active process in years without freeze or with thick snow cover. Snowfall evolution in recent decades in correlation with flow water and climate features provide the certainty that snow distribution also affects efficacy in runoff generation and moves the flow peak in rivers due to early snowmelt.
Recent evolution of the active layer in the Morenas Coloradas rock glacier, Central Andes, Mendoza, Argentina and its relation with kinematics
Authors: Trombotto-Liaudat D. , Bottegal E.
Published: July 2019

Between 2008 and 2016 the Morenas Coloradas rock glacier in the Central Andes of Mendoza showed different thermal characteristics at three monitoring sites in active layers, Balcón I (3560 m a.s.l.), Balcón I Superior (3590 m a.s.l.) and Balcón II (3770 m a.s.l.). These can be explained by various factors, not only external ones related to the climatic variability and altitude, but also by thermal-hydrological factors that destabilized its internal cryogenic structure. At Balcón I, situated on a sloping terrace of the rock glacier, a transient layer even showed definitive signs of permafrost degradation in the recent years, transforming it in a thermal talik. Long-term studies of surficial boreholes showed that the 0°C isotherm is higher in altitude than the active front of the rock glacier and it has risen 40 m in altitude since the 1990s. As consequence of the thermal changes of the active layer, the rock glacier shows abrupt movements, particularly in its terminal part. Thus geodesic measurements to obtain different speeds and directions were made. At the monitoring area of Balcón I Superior, which lies on a superimposed lobe, the geodesic measurement points revealed significant kinematic activity in the period May 2015 – February 2016, when the largest displacement was approximately 2 m to the South, developing an advance of the front over Balcón I. At Balcón II however, the points moved much less, in the order of 0.30 m yr-1. The present studies suggest that the largest cryogenic sedimentary movements are superficial, that is to say, they are located in the active layer and the supra-permafrost and are due to internal movements produced by melting water coming from the top of the cryoform, and from both sides of the upper basin of the valley.
The right to education as a fundamental human right
Authors: Zendeli Emine
Published: July 2019

The right to education is a fundamental human right proclaimed by Articles 13 and 14 of the United Nations International Covenant on Economic, Social and Cultural Rights (1966). Ratifying this document, state parties fully agree â€˜that education shall be directed to the full development of the human personality and the sense of its dignity, and shall strengthen the respect for human rights and fundamental freedomsâ€™. The right to education is considered as a fundamental human right in a series of other 20th century international documents, which guarantee and protect this right for everyone, irrespective of race, colour, religion, gender, social status, etc. This paper aims to respond to questions on the observance of this right and whether it has been limited. The research is based on international documents that regulate this specific category, as well as on the respective legislation and practice within educational institutions in the Republic of Macedonia.

Keywords: Education, fundamental human rights, covenant, law.

Cuando la cabeza duele, el cuerpo duele: usos y abusos en la provisión de oficios del superior gobierno del Nuevo Reino de Granada (finales del s. XVII)
Authors: Velasco Pedraza Julian Andrei
Published: July 2019

Este artículo analiza la provisión de oficios del superior gobierno del Nuevo Reino de Granada y las acusaciones por los abusos cometidos en la misma por parte de los presidentes gobernadores. La manera en que se desarrolló tal fenómeno es posible explicarla en virtud de las coordenadas culturales de aquella época, en la que tanto la justicia distributiva (como obligación del rey y sus representantes para con sus vasallos) como la reciprocidad de los vínculos sociales (don y contradon) se combinaban. La metodología de trabajo consistió en acudir a diversas fuentes normativas e institucionales desde una perspectiva histórico-jurídica y político-cultural, para comprender los usos y abusos de la provisión de oficios en su propio contexto. Se pudo comprobar que el conocimiento de los mecanismo institucionales cotidianos permite entender mejor las forma en la que los que proveyeron los oficios, trataron de sustentar las obligaciones de sus oficios y la de sus vínculos sociales.

Through this study, the author is expected to find outthe existence of peresean tradition and the meaning of pereseantradition to the community. This employed an explorative qualitativeresearch method. The research took place in Karek Village, Praya BaratDaya Sub District, Lombok Tengah Regency. The subject of research wasDarek villagers, in this case, taken using snowball sampling technique.The result of research showed that Peresean tradition is a traditional artof Sasak ethnic community in which two men are fighting against eachother (pepadu) using weapon made of rattan stick and shield. Inperesean tradition, there are rule and sanction in its implementation.Peresean performance is now conducted at certain times, e.g. on villageor regency anniversary day, wedding party, low-season, RI independenceday, or in guest welcoming event. Values contained in peresean traditionare life values including appreciating fraternity, friendship, economy,kinship, belief, culture, and art value. Meanwhile, the meaning ofperesean tradition includes a means of showing off man’s bravery,agility, and sturdiness, martial art, sportsmanship spirit, selfappreciation,establishing good relationship, and friendship. So,peresean traditional performance art in Sasak Lombok ethniccommunity has shifted viewed from its rule, meaning, andimplementation time aspects.

The high level of human activity in coastal areas has had an impact on seagrass beds. The advancement of satellite imaging technology makes monitoring seaweed conditions even easier. The purpose of this study was to identify the spectral reflectance patterns of different seagrass cover levels and make it the basis for mapping the seagrass condition on Barranglompo Island. Based on google earth has been determined 4 sampling stations that represent the spread of seagrass on Barranglompo Island. Each station is divided into 4 sub-stations from land to sea. Sampling of seagrass cover was carried out by the McKenzie (2003) method modified by close sampling, to 30 x 30 square meters following the spatial resolution of Landsat image 8. Each observation point was estimated the percentage of seagrass cover and the dominant species. Digital seagrass pixel extraction is performed from band 1 to 7 landsat 8 according to point position in the field and then grouped by cover class and condition. Seagrasses found in Barranglampo Island are 8 species: Enhalus acoroides, Thalassia hemprichii, Halophila ovalis, Cymodocea rotundata, Cymodocea serulata, Halodule uninervis, Halodule pinifolia and Syringodium isoetifolium. In general, Enhalus acoroides and Thalassia hemprichii have higher closure than other seagrass species. The spectral reflection of seagrass landscape imagery 8 OLI channel 1 - 7 is good enough to show the seagrass condition in bad category, good enough, and good. Spectral reflection of the seagrass has a peak on the green channel. The worse the seagrass condition the higher the spectral reflection. Seagrass with bad conditions has a low cover so that other substrates such as sand will contribute to the spectral value recorded by satellite sensors. This result will facilitate mapping of seagrass condition on small islands by using Landsat 8 OLI image.Keywords: seagrass condition, spectral reflection, landsat 8, South Sulawesi

Penelitian ini bertujuan untuk mengetahui pengaruh penambahan konsentrasi buah tomat terhadap sifat fisikokimia (TPT, viskositas, pH, kadar vitamin C, kadar air dan aktivitas antioksidan ) dan sensori selai semangka. Rancangan percobaan adalah Rancangan Acak Lengkap (RAL) dengan satu faktor yaitu kombinasi
perlakuan penambahan tomat pada selai buah semangka (70%:30%; 65%:35%, 60%:40%, 55%:45%, 50%:50%). Untuk melihat beda nyata antar perlakuan, dianalisis secara statistik menggunakan oneway ANOVA pada taraf α 0,05 dilanjutkan dengan menggunakan uji Duncan Multiple Range Test (DMRT) pada taraf α 0,05. Penambahan tomat pada konsentrasi berbeda tidak berpengaruh terhadap total padatan terlarut (TPT), viskositas dan sensori (warna, aroma, rasa, kemudahan oles, overall), tetapi berpengaruh terhadap pH, kadar vitamin C,
kadar air, aktivitas antioksidan dan sensori (tekstur) selai semangka. Nilai TPT selai semangka meningkat kemudian turun diatas penambahan tomat 35%, sedangkan nilai viskositasnya hampir sama pada semua sampel. Nilai TPT semua sampel sudah memenuhi persyaratan SNI. Nilai pada kadar vitamin C, kadar air dan aktivitas antioksidan meningkat, berbanding terbalik dengan pH. Nilai pH terendah (3,79), kadar vitamin C tertinggi (27,64mg/100gr), dan aktivitas antioksidan terbesar (6,013%DPPH/mg) didapatkan dari perbandingan semangka tomat 50%:50%. Perbandingan selai semangka dan tomat yang memiliki nilai sensori tertinggi adalah 60%:40%.

Penelitian ini bertujuan untuk mengetahui kinetika pengeringan yaitu laju pengeringan dan kebutuhan energi pada pengeringan chips sukun, dan untuk mengetahui karakteristik (kadar air, kadar amilosa, derajat putih, viskositas, kelarutan, swellling power, gugus fungsi) tepung sukun. Perancangan penelitian menggunakan rancangan acak faktorial (RAF) yang terdiri dari dua faktor yaitu perlakuan (nonmodifikasi dan modifikasi asam laktat 1%) dan suhu pengeringan (60°C, 65°C dan 70°C). Setiap perlakuan dilakukan tiga ulangan sampel dengan dua kali ulangan analisa. Hasil penelitian menunjukkan bahwa semakin tinggi suhu pengeringan dan penambahan asam laktat menyebabkan penurunan kadar air chips sukun, mempercepat laju pengeringan dan menurunkan kebutuhan energi pengeringan. Semakin tinggi suhu pengeringan dan penambahan asam laktat menyebabkan menurunnya kadar air dan derajat putih tepung sukun, meningkatnya kadar amilosa, viskositas, kelarutan dan swelling power tepung sukun. Analisis gugus fungsi (FTIR) menunjukkan adanya serapan gugus karbonil pada bilangan gelombang 1735 cm -1 dari tepung sukun yang termodifikasi asam laktat.

Mobile robots equipped with camera sensors are required to perceive surrounding humans and their actions for safe and autonomous navigation. In this work, moving humans are the target objects. For robot vision, real-time performance is an important requirement. Therefore, we propose a robot vision system in which the original images captured by a camera sensor are described by optical flow. These images are then used as inputs to a classifier. For classifying images into human and not-human classifications, and the actions, we use a convolutional neural network (CNN), rather than coding invariant features. Moreover, we present a local search window as a novel detector for clipping partial images around target objects in an original image. Through the experiments, we ultimately show that the robot vision system is able to detect moving humans and recognize action in real time.
