ASSISTÊNCIA DE ENFERMAGEM AO PACIENTE COM ESTOMIA INTESTINAL: UMA REVISÃO BIBLIOGRÁFICA
Authors: Pereira Vasconcelos Karla , Tamires Lacerda Silva Cleisla
Published: April 2020

OBJETIVOS: identificar e descrever os cuidados de enfermagem ao paciente com estomia intestinal. MÉTODOS: Trata-se de uma revisão na literatura de artigos publicados a partir de 2015 a 2019, nas bases de dados Lilacs, Pubmed, SciELO e Google Acadêmico. RESULTADOS: Foram selecionados 9 artigos que estavam dentro da temática abordada e dos critérios de inclusão para realização deste estudo. Foi observado que a assistência de enfermagem, na grande maioria dos casos eram restritas a questões fisiológicas, como o uso correto do dispositivo coletor. Percebeu-se ainda, deficiência em orientações relacionadas ao autocuidado, apoio emocional, psicológico e sexualidade, além de déficit em questões relacionadas a dispositivos que garantem os direitos legais dos estomizados. CONCLUSÃO: A assistência de enfermagem para pacientes estomizados deve ser planejada de modo a complementar seus aspectos fisiológico, psicológico, emocionais, sexuais e sociais, na perspectiva de prestar uma assistência de forma holística. Orientações fragmentadas e pautadas apenas em questões fisiológicas demostram uma formação fortemente pautada no modelo biomédico e carece de ser trabalhada na acadêmia, para que assim seja prestada assistência de qualidade. Desse modo, deve haver uma melhora do processo educativo dos enfermeiros aos pacientes estomizados, de forma que englobe o paciente de modo integral, além de ser crucial a discurssão no meio acadêmico a respeito da assistência de enfermagem ao paciente ostomizado, sendo um tema que carece de mais pesquisas e maior socialização durante a formação dos profissionais de enfermagem. Palavras chave: assistencia de enfermagem; estomia; pacientes.
METHODOLOGY OF TRANSLATION ARABIC TEXT IN CHAPTER SOLAT IN KITAB BAHRUL MAZI
Authors: Ahmad Abdul Mu’iz , Muhamad Romli Taj Rijal
Published: April 2020

According to Koharudin (2004, No. 3, p. 56, Dalam M. Hisyam, Mikdar & Dawilah, 2012), ‘Kitab Jawi’ also known as ‘Kitab Kuning’. In the early 20th century, the word ‘Yellow’ was called because the color of the paper of the book was yellow and the original paper material for printing came from Central Asia. In addition, the technique of translating the old or yellow Kitab is still in an old form which is a literal translation. Therefore, this research was conducted to analyse the translation from Chapter of Prayer in ‘Kitab Bahrul Mazi’. The researcher used qualitative data with a selection of 10 out of 88 ‘Bab Hadis’ which contain in the Kitab. Eugene Nida’s Theory (1964) was used as a guide to be developing a research framework that aimed to analyse the alternative methods which are suitable for the Kitab. Because of that, this study is expected to make it easier for the readers especially to understand the method of translation and to be able to practice the teachings of the Prophet Muhammad correctly and faithfully.

Published: April 2020

The concept of an innovation ecosystem has become commonplace and is increasingly included in official documents of countries and organizations, but it doesn’t have an unambiguous interpretation: representatives of various branches of science put different meanings into the concept of an innovation ecosystem. Nowadays, the concept of an innovation ecosystem is in the stage of cognition and identification. An innovation ecosystem is a term used to describe a large and diverse range of participants and resources that promote and are necessary for continuous innovation in a modern economy. The article reveals the essence, the basis of functioning and the concept of an innovation ecosystem by drawing an analogy between innovation and biological ecosystems. The authors highlighted the basic elements of the innovation ecosystem and their relationship at different stages of the innovation life cycle. A historical excursion into the emergence and formation of the concept of an innovation system, an innovation ecosystem is carried out. The definitions of the terms innovation system, and innovation ecosystem by various leading scientists from Ukraine and from around the globe are given. The authors also disclosed the principle of the innovation ecosystem formation at the levels of innovation development as: global (supranational), national, regional, corporate and individual. A detailed analysis (objective, framework, world examples) of each level of the innovation ecosystem is carried out. The authors also gave examples and principles of the formation of well-known, successful and productive innovation ecosystems of Ukraine such as: UNIT.City, Sikorsky Challenge, All-Ukrainian Innovation Festival, Science Park of Kyiv Taras Shevchenko University, Vernadsky Challenge, Interregional Technology Transfer Network (Ukrainian Institute of Scientific and Technical Expertise and Information).

Published: April 2020

Spodoptera litura (Lepidoptera: Noctuidae) larvae are polyphagous insects whose populations cause damage to various types of plantations, horticulture, and food so that control efforts need to be done. One way to control the environment of environmentally friendly S. litura larvae is to use a plant-based insecticide, a mixture of A. squamosa leaf extract and C. domestica rhizome (test extract appendix). The purpose of this study was to determine the subletal effect of the test extract mixture on S. litura larvae, namely the duration of larvae and pupae stage, pupae weight, morphology and imago viability, and the ability of female imago to lay eggs to produce offspring. The test was carried out by the method of feed dip into the test extract mixture. Data on pupae weight were analyzed with ANOVA, followed by Duncan's further test with a 5% confidence level using SPSS 21 program. The results showed that the test extract mixture extended the stages of larvae and pupae, reduced pupa weight, imago wings did not develop fully, reduced imago size, and did not imago able to produce eggs. The results of this study could then be further tested on a greenhouse scale and photochemical analysis of a test extract mixture to determine bioactive compounds that act as plant-based insecticides.

The central portions of the condensed phase system Cu–Fe–Se were investigated by means of dry syntheses in evacuated silica glass tubes at 900, 750, 600, 500, 450, 350, and 300 °C. Synthesis products were studied by reflected-light microscopy and electron microprobe analyses. The field of sulfide melt is extensive at 900 °C and retreats progressively towards the Cu–Se side at 750 °C; residual selenide melt persists at 600 °C. The selenium analogue of iss was found only at and below 600 °C; eskebornite becomes individualized at and below 500 °C, whereas the selenium analogue of bornite solid solution is present at all investigated temperatures, although with reduced extent on temperature decrease. The three iron selenides (β, γ, δ) display considerable solubility of copper, which for the mackinawite-like β FeSe reaches 14 at.% Cu at 300 °C. FeSe2 displays an immiscibility gap with isotropic solid solution (Cu,Fe)Se2, the composition of which gradually changes towards Cu-rich with decreasing temperature. Similarities and differences with the sulfur-based system are highlighted.

Adsorptive removal of bulky dye molecules from water with mesoporous polyaniline-derived carbon
Authors: An Hyung Jun , Park Jong Min , Khan Nazmul Abedin , Jhung Sung Hwa
Published: April 2020

Polyaniline-derived carbon (PDC) was obtained via pyrolysis of polyaniline under different temperatures and applied for the purification of water contaminated with dye molecules of different sizes and charge by adsorption. With increasing pyrolysis temperature, it was found that the hydrophobicity, pore size and mesopore volume increased. A mesoporous PDC sample obtained via pyrolysis at 900 °C showed remarkable performance in the adsorption of dye molecules, irrespective of dye charge, especially in the removal of bulky dye molecules, such as acid red 1 (AR1) and Janus green B (JGB). For example, the most competitive PDC material showed a Q0 value (maximum adsorption capacity) 8.1 times that of commercial, activated carbon for AR1. The remarkable adsorption of AR1 and JGB over KOH-900 could be explained by the combined mechanisms of hydrophobic, π–π, electrostatic and van der Waals interactions.

Published: April 2020

The reductive carbonylation of aryl iodides to aryl aldehydes possesses broad application prospects. We present an efficient and facile Rh-based catalytic system composed of the commercially available Rh salt RhCl3·3H2O, PPh3 as phosphine ligand, and Et3N as the base, for the synthesis of arylaldehydes via the reductive carbonylation of aryl iodides with CO and H2 under relatively mild conditions with a broad substrate range affording the products in good to excellent yields. Systematic investigations were carried out to study the experimental parameters. We explored the optimal ratio of Rh salt and PPh3 ligand, substrate scope, carbonyl source and hydrogen source, and the reaction mechanism. Particularly, a scaled-up experiment indicated that the catalytic method could find valuable applications in industrial productions. The low gas pressure, cheap ligand and low metal dosage could significantly improve the practicability in both chemical researches and industrial applications.

Published: April 2020

Pada tempat parkir yang berada di Indonesia khusunya Surabaya masih menggunakan tiket yang di print pada saat masuk ke tempat parkir. Tiket ini akan disimpan sampai pada saat keluar dari tempat parkir, dan baru akan diserahkan kepada petugas parkir yang berada di gerbang keluar. Pada gerbang keluar, petugas akan melakukan scan ticket di mesin dan akan memberitahu berapa jumlah yang harus dibayarkan. Hal ini dapat terasa lambat dan kurang efisien, sehingga dapat menimbulkan suatu kendala pada saat keluar dimana kendalanya adalah penumpukan mobil yang membuat keluar dari tempat parkir terhambat dan juga harus menyediakan uang dimana jika uang tersebut memiliki kembalian maka harus menunggu petugas untuk memberikan kembalian. Flutter adalah framework native untuk membuat aplikasi cross platform Android dan iOS. Flutter menggunakan Dart sebagai Bahasa pemrograman. Pada sistem ini, pengguna yang mendaftar sebagai member dapat melakukan parkir ke tempat parkir yang tersedia dengan menggunakan aplikasi tanpa memakai tiket. Selain fitur untuk parkir, terdapat fitur untuk melakukan subscribe atau booking pada tempat parkir, dan melakukan report. Pengguna juga dapat mendaftar menjadi owner, dimana owner dapat melakukan setting parkiran, mengirimkan newsfeed, dan melakukan review untuk report yang dikirimkan oleh member. Dengan dibuatnya sistem ini, diharapkan pengguna dapat terbantu untuk melakukan parkir agar menjadi lebih mudah dan efisien. Dalam pembuatan sistem, terdapat beberapa kendala seperti proses buka dan tutup gerbang menggunakan mikrokontroler dimana gerbang terkadang mengalami delay pada saat melakukan proses.
The Satellite Luminosity Function of M101 into the Ultra-faint Dwarf Galaxy Regime
Authors: Bennet P. , Sand D. J. , Crnojević D. , Spekkens K. , Karunakaran A. , Zaritsky D. , Mutlu-Pakdil B.
Published: April 2020

We have obtained deep Hubble Space Telescope (HST) imaging of four faint and ultra-faint dwarf galaxy candidates in the vicinity of M101–Dw21, Dw22, Dw23 and Dw35, originally discovered by Bennet et al. Previous distance estimates using the surface brightness fluctuation technique have suggested that these four dwarf candidates are the only remaining viable M101 satellites identified in ground-based imaging out to the virial radius of M101 (D ≈ 250 kpc). Advanced Camera for Surveys imaging of all four dwarf candidates shows no associated resolved stellar populations, indicating that they are thus background galaxies. We confirm this by generating simulated HST color–magnitude diagrams of similar brightness dwarfs at the distance of M101. Our targets would have displayed clear, resolved red giant branches with dozens of stars if they had been associated with M101. With this information, we construct a satellite luminosity function for M101, which is 90% complete to M

V
 = −7.7 mag and 50% complete to M

V
 = −7.4 mag, that extends into the ultra-faint dwarf galaxy regime. The M101 system is remarkably poor in satellites in comparison to the Milky Way and M31, with only eight satellites down to an absolute magnitude of M

V
 = −7.7 mag, compared to the 14 and 26 seen in the Milky Way and M31, respectively. Further observations of Milky Way analogs are needed to understand the halo-to-halo scatter in their faint satellite systems, and connect them with expectations from cosmological simulations.
Une décennie de « Caux Round Table » : le réseau patronal transnational du Réarmement moral, entre tournant néo-libéral et éthique d’entreprise (1986-1996)
Authors: Bonvin Audrey
Published: April 2020

Notre contribution vise à présenter la première décennie de l’existence d’un groupe patronal américano-nippo-européen encore méconnu par l’historiographie contemporaine, portant le nom de « Caux Round Table » (CRT). Se réunissant annuellement dès 1986 en Suisse, sur les hauteurs de Montreux dans le Caux-Palace, celui-ci rassemble des dirigeants d’entreprise à l’initiative de Frederik Jacques Philips, Olivier Giscard d’Estaing et Ryuzaburo Kaku. L’article présente le contexte des conférences industrielles qui précèdent les CRT avant de traiter de leur réseau, composé majoritairement de patrons de multinationales du secteur secondaire, pour la plupart actifs dans les milieux chrétiens à titre privé. Est ensuite abordée la concrétisation de ces discours dans l’espace public sous la forme d’un guide de management éthique en 1994. Nous lions la définition du « capitalisme moral » des CRT à celle de la chevalerie économique d’Alfred Marshall. Enfin, nous soulignons l’importance qu’il y a à prendre en compte la sociabilité religieuse des élites dans l’analyse de réseaux transnationaux, cette approche permettant d’appréhender dans toute sa complexité tant le profil des acteurs et leurs motivations parfois paradoxales, mais également l’origine, la nature et l’ampleur de leur collaboration.
A Systematic Review of Subclinical Keratoconus and Forme Fruste Keratoconus
Authors: Henriquez Maria A. , Hadid Marta , Izquierdo Luis
Published: April 2020

PURPOSE:

To identify the definitions used for the terms sub-clinical keratoconus and forme fruste keratoconus in published articles.

METHODS:

This was a prospective, systematic literature review of the electronic database in PubMed, the Cochrane Library, and LILACS Database of all studies using the keywords “subclinical keratoconus” and/or “forme fruste keratoconus” until August 18, 2017. Two independent reviewers analyzed the data. The inclusion criteria for articles were having analyzed subclinical keratoconus or forme fruste keratoconus eyes with a sample size greater than 10 eyes; containing the definition of subclinical keratoconus or forme fruste keratoconus; and the quality of published reports was assessed using standards quality index methods. The following aspects of the selected articles were then analyzed: inclusion criteria for definition and technology used.

RESULTS:

A total of 198 and 95 studies, respectively, including the definition of subclinical keratoconus and forme fruste keratoconus were collected in an initial search, of which 165 and 73 studies, respectively, were excluded. Definitions for subclinical keratoconus and forme fruste keratoconus included the criteria of having keratoconus in the fellow eye in 72.72% (24 of 33) and 77.27% (17 of 22) of the articles, respectively. A total of 96.97% (32 of 33) and 90.90% (20 of 22) of the studies used more than one parameter to define subclinical keratoconus and forme fruste keratoconus, respectively. The most common extra parameters included normal slit-lamp examination and cornea on slit-lamp biomicroscopy and inferior-superior asymmetry and/or bowtie pattern with skewed radial axes.

CONCLUSIONS:

This review demonstrates the lack of unified criteria to define subclinical keratoconus and forme fruste keratoconus. According to the literature review, the most common subclinical keratoconus definition used refers to an eye with topographic signs of keratoconus and/or suspicious topographic findings under normal slit-lamp examination and keratoconus in the fellow eye and the most common forme fruste keratoconus definition refers to an eye with normal topography, normal slit-lamp examination, and keratoconus in the fellow eye.

Published: April 2020

Mental health presents a growing public health concern worldwide with mental illnesses affecting people’s quality of life and causing an economic impact on societies. The rapidly increasing demand for mental healthcare is calling for new  ways of disseminating mental health knowledge and for supporting people with mental health illnesses. As an alternative to traditional mental health therapies and treatments, mental health self-assessment and self-management tools become widely available to the public. While such tools can potentially offer more timely personalised support, individuals seeking help are faced with the challenge of making an appropriate choice from an exhaustive number of online tools, mobile apps, and support programs.In this article, we present myGRaCE – a self-assessment and self-management mental health tool made accessible to users via Augmented Reality technologies. The advantage of the system is that it provides a direct pathway to relevant and reliable mental health resources and offers a positive incentive and interventions for at-risk users. The system offers service users the resources to gain a better understanding of their mental state and increase control of their mental health conditions via self-monitoring and self-help.

The recent emergence of a new coronavirus (COVID-19) has gained a high cover in public media and worldwide news. The virus has caused a viral pneumonia in tens of thousands of people in Wuhan, a central city of China. This short paper gives a brief introduction on how the demand for information on this new epidemic is reported through Google Trends. The reported period is 31 December 2020 to 20 March 2020. The authors draw conclusions on current infodemiological data on COVID-19 using three main search keywords: coronavirus, SARS and MERS. Two approaches are set. First is the worldwide perspective, second – the Chinese one, which reveals that in China this disease in the first days was more often referred to SARS then to general coronaviruses, whereas worldwide, since the beginning, it is more often referred to coronaviruses.
The Upgrading of Ha Tinh Ilmenite to Synthetic Rutile by Becher Process
Authors: Duong Binh Ngoc , Truong Than Ngoc , Nguyen Thao Thi
Published: April 2020

Becher process was applied for upgrading Ha Tinh ilmenite concentrate (54-55% TiO2) to synthetic rutile. The process includes reduction of ilmenite concentrate using anthracite coal as reductant, followed by aeration of reduced ilmenite in ammonium chloride solution (NH4Cl). The controlled parameters were temperature and NH4Cl concentration. The results showed that the degree of iron metallization was 83% after 4 hours of reduction at 1150 °C. Most of the metallic iron (98%) was successfully rust after 9 hours of aeration at 70°C, 7/1 of liquid/solid ratio (L/R), 4 liter/minutes (L/min) of air flow rate and 0.5% of NH4Cl concentration. The addition of acetic acid or citric acid in to the aeration solution has facilitated the aeration process. The aeration time could be vastly reduced when ammonium chloride solution used in aeration was replaced by the mixture of CH3COOH 0.075M and CH3COONa. Leaching with H2SO4 15% has improved TiO2 content from 82% in the aerated ilmenite to approximately 89% in synthetic rutile. The research work has proved that Becher process is applicable for the beneficiation of Ha Tinh ilmenite concentrate.
Microstructures in HAZ after Heat Treatment of Carbon Steel and Austenitic Stainless Steel Welds
Authors: Nhung Le Thi , Khanh Pham Mai , Thang Nguyen Duc , Hoang Bui Sy
Published: April 2020

The influence of post weld heat treatments (PWHT) at 400°C, 600°C, 900°C on microstructures in heat affected zone (HAZ) of dissimilar welds between carbon steel and austenitic stainless steel was studied. As-welded condition, the fully Martensitic layer along the fusion line, Widmanstatten Ferrite, Bainite, Pearlite phases in the HAZ of carbon side and the fully austenitic zone in the weld metal can be observed. After PWHT, the microstructures of these zones were dramatically modified as a result of carbon diffusion from the carbon steel toward the weld metal. Decarburization of the base metal led to the formation of a zone with large Ferrite grains. Bainite or fine Pearlite were formed by carbon diffused to both the interfacial Martensite and the purely Austenite zone. The lowest hardness value in the decarburization zone was 92HV on average after PWHT at 900°C and the peak hardness value that was documented in the carburize zone with 366HV at 600°C. Carbides precipitation (M23C6, M7C3) were found in both the HAZ of carbon steel and austenitic stainless steel.
Change in the Strength of Steel Grade 11 Loaded at Room Temperature
Authors: Bui Anh Hoa , Nguyen Thu Hien , Kieu Van Hung , Dinh Xuan Hiep , Nguyen Cao Son , Phung Thi To Hang
Published: April 2020

Steel grade 11 is widely used to fabricate superheater pipe in the thermal power plant. Since the steam has a high temperature (above 300oC) and pressure (max. 20 MPa), lifetime of the tube/pipe decreases or the failure occurs during the operation. Problems of the steel include micro-crack, creep degradation, pit corrosion, mechanical failure, etc.; and increasing working time raises the failure potential and decreases the economy if the thermal plant has to stop operating. This research investigated the change in the mechanical properties of steel grade 11 (ASTM A335) loaded constantly at room temperature. The steel specimens were cut from a new pipe P11, hanged under various stresses (6.45 – 9.68 – 12.9 MPa) for 2160 and 4320 hours. After the loads were removed, the steel specimens were tensile tested and observed by optical microscopy and SEM. The results shown that strengths of the steel increased with increased the stress for 2160 hours, but slightly decreased for 4320 hours. There was no significant change of the microstructure including 87 vol.% ferrite and 13 vol.% pearlite, and the grain sizes were estimated as about 18 μm for all conditions. It was considered that a deformation hardening occurred in the beginning stage of loading, but the creep degradation started as the loading time was lengthened. The fact that a significant change in the microstructure was not observed in the present steels revealed that high temperature played an important role in degradation of the practical steels.

Twin-wire indirect arc welding (TWIAW) is a novel welding technology with high deposition efficiency and low dilution rate, which is especially suitable for wear-resistant surfacing. In this study, wear-resistant surfacing layer was prepareted on low-carbon steel using flux cored wire by TWIAW. The influence of welding parameters on droplet transition and the surfacing layers property were studied. In the TWIAW process, due to rapidly solidification of the weld pool, wear-resistant reinforced phase synthesized through metallurgical reaction mainly finished in the droplet transfer stage using the welding arc. The welding parameters not only affected the droplet transfer frequency and size, but also affected the microstructure of the surfacing layer. The main reinforcing phase in the surfacing layer was chromium carbide. "Lean carbon" phenomenon could be observed along the grain boundary in the matrix when the welding current was small. The increasing of the welding current could prompt the metallurgical reaction. The wear resistance of the surfacing layers depends on the distribution of the chromium carbide and the matrix microstructure.

Central tolerance prevents autoimmunity, but also limits T cell responses to potentially immunodominant tumor epitopes with limited expression in healthy tissues. In peripheral APCs, γ-IFN–inducible lysosomal thiol reductase (GILT) is critical for MHC class II–restricted presentation of disulfide bond–containing proteins, including the self-antigen and melanoma Ag tyrosinase-related protein 1 (TRP1). The role of GILT in thymic Ag processing and generation of central tolerance has not been investigated. We found that GILT enhanced the negative selection of TRP1-specific thymocytes in mice. GILT expression was enriched in thymic APCs capable of mediating deletion, namely medullary thymic epithelial cells (mTECs) and dendritic cells, whereas TRP1 expression was restricted solely to mTECs. GILT facilitated MHC class II–restricted presentation of endogenous TRP1 by pooled thymic APCs. Using bone marrow chimeras, GILT expression in thymic epithelial cells (TECs), but not hematopoietic cells, was sufficient for complete deletion of TRP1-specific thymocytes. An increased frequency of TRP1-specific regulatory T (Treg) cells was present in chimeras with increased deletion of TRP1-specific thymocytes. Only chimeras that lacked GILT in both TECs and hematopoietic cells had a high conventional T/Treg cell ratio and were protected from melanoma challenge. Thus, GILT expression in thymic APCs, and mTECs in particular, preferentially facilitates MHC class II–restricted presentation, negative selection, and increased Treg cells, resulting in a diminished antitumor response to a tissue-restricted, melanoma-associated self-antigen.

Esta investigación se sitúa en el contexto de las desigualdades educativas en Chile y de la relación entre la estructura social y las trayectorias educativas. Se analiza el concepto de "posición docente" de los formadores con relación a estudiantes de colegios privados y municipales y su diferencia en la esfera social. La posición docente que se aborda en dos ámbitos: el sentir hacia la riqueza y pobreza y los discursos en el ámbito pedagógico de los estudiantes de ambos establecimientos.  Es un estudio cualitativo, en el que se entrevistó a 27 formadores de estudiantes de las carreras de Pedagogía Educación Básica y Parvularia, pertenecientes a seis universidades de tres regiones del país. Se concluye que no existen diferencias significativas entre instituciones y carreras. Los formadores manifiestan una dualidad y tensión entre los dos ámbitos de estudio, expresan confianza en que la pobreza puede ser superada a través de las oportunidades de la escuela, pero al mismo tiempo refuerzan el déficit de los estudiantes, familias y la escuela pública. Esta tensión, entre las posibilidades de cambio y el déficit, debilita las posibilidades de lo educativo.

Los sostenedores públicos chilenos desempeñan un rol central en el contexto de la Ley de Desmunicipalización (Ley No. 21.040), que mandata el traslado de los establecimientos educacionales desde los municipios a nuevos Servicios Locales de Educación Pública, buscando cambiar la forma de hacer y entender la educación en Chile. Este estudio caracteriza mediante autoreporte la gestión de la convivencia escolar a nivel de sostenedores en las dimensiones de conocimiento de las escuelas y su territorio, gestión de redes y el reconocimiento del logro y cambio. Además, se identifican características de los sostenedores que promueven el desarrollo de estas dimensiones. Los resultados muestran una amplia variabilidad de la gestión de la convivencia escolar entre los sostenedores nacionales. Al mismo tiempo, los resultados comparativos muestran diferencias significativas respecto a las horas de dedicación, tamaño de los equipos y capacitación en convivencia escolar. Lo anterior destaca la necesidad de contar con sostenedores que dispongan del tiempo y personal necesarios|, y que tengan formación especializada en convivencia escolar para lograr los cambios requeridos por la reforma.
Las redes sociales virtuales: Espacios de socialización y definición de identidad

El propósito del estudio ha sido identificar los mecanismos que influyen en la construcción de identidades on-line de las y los adolescentes, como correlato de la alteridad, es decir, las formas de relacionarse y de reconocerse en los otros/otras; y por esto se analizan 36 entrevistas etnográficas semiestructuradas, aplicadas a estudiantes entre 12 y 18 años, pertenecientes a todos los sectores sociales de la región de Valparaíso, Chile. El diseño metodológico utiliza la técnica de análisis de contenido, priorizando una perspectiva interpretativa crítica, que levanta categorías vinculadas a la autodefinición y procesos de identificación del sujeto, que,  desde la construcción de la identidad en red, se acentúan y enfatizan en la configuración identitaria, la aceptación y el reconocimiento de los otros, induciendo, a menudo, una subjetividad moldeada a las exigencias de una audiencia siempre más exigente, que puede limitar la libertad de gestos, opiniones y específicamente la autonomía propia de una moral autónoma.

Este número de Psicoperspectivas ofrece un conjunto de artículos que abordan, entre otros temas, los procesos de liderazgo en contextos educativos, gestión y convivencia escolar, sistemas familiares diversos (LGTBI), nuevas formas de organización del trabajo, y el papel de las redes sociales en la construcción de identidades. Constituyen apuestas que contribuyen a situar la dimensión ético-valórica que subyace a los distintos escenarios de la investigación social, contribuyendo a visibilizar diversas alteridades, entre ellas grupos minoritarios y comunidades precarizadas. Ofrecen, de esta manera, la posibilidad de pensar en conceptualizaciones alternativas a la vez que visibilizan dinámicas de opresión y marginalización presentes en distintos contextos sociales y hablan, por tanto, de nuestras genealogías de indignación locales.

Abstract. The concentrations of submicron aerosol particles in maritime regions around
Antarctica are influenced by the extent of sea ice. This effect is two ways:
on one side, sea ice regulates the production of particles by sea spray
(primary aerosols); on the other side, it hosts complex communities of
organisms emitting precursors for secondary particles. Past studies
documenting the chemical composition of fine aerosols in Antarctica indicate
various potential primary and secondary sources active in coastal areas, in
offshore marine regions, and in the sea ice itself. In particular,
beside the well-known sources of organic and sulfur material originating
from the oxidation of dimethylsulfide (DMS) produced by microalgae, recent
findings obtained during the 2015 PEGASO cruise suggest that
nitrogen-containing organic compounds are also produced by the microbiota
colonizing the marginal ice zone. To complement the aerosol source
apportionment performed using online mass spectrometric techniques, here we
discuss the outcomes of offline spectroscopic analysis performed by nuclear
magnetic resonance (NMR) spectroscopy. In this study we (i) present the
composition of ambient aerosols over open-ocean waters across bioregions,
and compare it to the composition of (ii) seawater samples and (iii) bubble-bursting aerosols produced in a sea-spray chamber onboard the ship. Our
results show that the process of aerosolization in the tank enriches primary
marine particles with lipids and sugars while depleting them of free
amino acids, providing an explanation for why amino acids occurred only at
trace concentrations in the marine aerosol samples analyzed. The analysis of
water-soluble organic carbon (WSOC) in ambient submicron aerosol samples
shows distinct NMR fingerprints for three bioregions: (1) the open Southern
Ocean pelagic environments, in which aerosols are enriched with primary
marine particles containing lipids and sugars; (2) sympagic areas in the
Weddell Sea, where secondary organic compounds, including methanesulfonic
acid and semivolatile amines abound in the aerosol composition; and (3)
terrestrial coastal areas, traced by sugars such as sucrose, emitted by land
vegetation. Finally, a new biogenic chemical marker, creatinine, was
identified in the samples from the Weddell Sea, providing another
confirmation of the importance of nitrogen-containing metabolites in
Antarctic polar aerosols.
Combined Simulation and Optimization Framework for Irrigation Scheduling in Agriculture Fields

Abstract. In the context of growing evidence of climate change and the fact that agriculture uses about 70 % of all the water available for irrigation in semi-arid areas, there is an increasing probability of water scarcity scenarios. Water irrigation optimization is therefore one of the main goals of researchers and stakeholders involved in irrigated agriculture. Irrigation scheduling is often conducted based on simple water requirement calculations without accounting for the strong link between water movement in the root zone, soil-water-crop productivity and irrigation expenses. In this work, we present a combined simulation and optimization framework aimed at estimating irrigation parameters that maximize the crop net margin. The simulation component couples the movement of water in a variably saturated porous media driven by irrigation with crop water uptake and crop yields. The optimization component assures maximum gain with minimum cost of crop production during a growing season. An application of the method demonstrates that an optimal solution exists and substantially differs from traditional methods. In contrast to traditional methods, results show that the optimal irrigation scheduling solution prevents water logging and provides a more constant value of water content during the entire growing season within the root zone. As a result, in this case, the crop net margin cost exhibits a substantial increase with respect to the traditional method. The optimal irrigation scheduling solution is also shown to strongly depend on the particular soil hydraulic properties of the given field site.
