Slang Language in Indonesian Social Media
Authors: Budiasa I Gede
Published: June 2021

Slang is a phenomenon of using language variations that arise as a result of language development and as well as a social dynamic in society in the realm of language. Slang in Indonesian is referred to as bahasa gaul and is mainly used by young people when communicating with other groups. Currently, the appearance of slang in the conversations of young people is very high, especially when viewed through interactions on social media such as Facebook, Instagram and Youtube. The emergence of YouTubers and celebgrams also has an impact on the wider spread and use of slang words today because slang words are one of the language styles that is often used by them.

Therefore, this study attempts to analyse more deeply the form, function and meaning of existing slang, especially those used in social media. This research is qualitative in nature with documentation methods in data collection. The data was obtained through observations about the use of slang on social media (Facebook, Instagram, YouTube, Whats App), then the slang found is classified into the type and formation of words, followed by an analysis of the functions and meanings of slang in social media today. Based upon Allan & Burridge (2006) the findings show that the forms of slang found on social media are very diverse such as Fresh and Creative, Flippant, Imitative, Acronyms and Clipping. This indicates that social media users, especially the younger generation, are very creative and active in forming new slang words.

 

Keywords: slang, social media, acronym, flippant, clipping.

Authors: Rodrigues da Cruz Talita , Soriano Pedro Costa
Published: June 2021

O presente artigo parte da perspectiva de interdisciplinaridade entre Direitos Humanos e Direito Agrário, com o escopo voltado para a Segurança Alimentar e Nutricional. Discutimos a problemática da fome, ou seja, do não cumprimento por parte do Estado e da sociedade civil do que é estabelecido constitucionalmente como Direito Humano Fundamental: A Segurança Alimentar e Nutricional (ou simplesmente SAN). Pesquisamos os métodos razoáveis para que se possa evoluir no sentido da distribuição equânime de terras agricultáveis e de alimentos de qualidade, bem como as razões pelas quais boa parte da população brasileira tem vivido subnutrida há séculos. Chega-se à conclusão de que é necessária uma Reforma Agrária estrutural dirigida pelo Estado, para romper os paradigmas seculares dos latifúndios monocultores e exportadores, e substituí-los paulatinamente por terras coletivas, destinadas à Agricultura Familiar, que vale lembrar, é a grande responsável pela produção dos alimentos consumidos pelo mercado interno brasileiro.

Authors: Hameed Firas J. , Ibrahim Isam M.
Published: June 2021

In this work, polypyrrole (PPy) composites were chemically prepared by a chemical oxidation method. Also, Tungsten Trioxide (WO3) nanoparticles were prepared and added in certain proportions to PPy. The structure properties were studied for the polypyrole and tungesten trioxide separately before mixing them together. The X-ray diffraction (XRD) analysis revealed a hexagonal WO3 and a triclinic PPy. It was observed that the nano-composite prepared by the addition of WO3  with 10 and 20% volume ratios to PPy shows a triclinic phase with the presence of hexagons. The molecular structures of PPy, WO3, and PPy–WO3 nano composites were depicted by Fourier-transform infrared spectroscopy (FTIR) in the scope of 400–4000 cm-1. The supercapcitors of PPy and PPy-WO3 were examined by calculating the figure of merit of the electrode (PPy and PPy-WO3) using cyclic voltammetry (CV), galvanostatic charge and discharge (GCD), and electrochemical impedance spectroscopy (EIS) techniques. It was found that the highest value of capacity (266.62 F/g) is obtained at 20% WO3 ratio.

Published: June 2021

Relevance. Acute respiratory failure (ARF) and acute cardiopulmonary failure (ACPF) are unavoidable, and often – the leading syndromes in any critical condition, especially in case of multiple organ failure syndrome as a regular stage in the course of previously incurable conditions. Even a full range of intensive care measures in this category of patients does not always give the desired result. According to various authors, with the development of acute respiratory distress syndrome, the mortality rate reaches 80 %.Intention is to determine the role of the aviation medical teams of the emergency medical service-disaster medicine in ensuring the timely availability of high-tech methods for patients who need them, regardless of the patient’s location.Methodology. Activities of the aviation medical teams of the Scientific and Practical Center for Emergency Medical Care of the Moscow City Health Department for the medical evacuation of patients and victims in emergency situations with ARF and ACPF were analyzed.Results and Discussion. There were analyzed interactions of aviation medical teams with the emergency medical response units of the territorial center for disaster medicine and with medical organizations during the medical evacuation of patients with ARF and ACPF. An algorithm and a scheme of interaction between air medical teams are proposed to optimize medical evacuation of these patients.Conclusion. An analysis of the activities of air medical teams revealed their advantages in providing care for patients with ARF and ACPF.

Published: June 2021

Relevance. The problem of organizing specialized medical care in emergency forms for children is caused by three groups of reasons: the presence at the junction of several adult and pediatric medical specialties, the medical and geographical features of the country and the lack of a unified regulatory framework.Intention. To increase the availability of medical services and reduce regional inequality in their distribution. A model of organizing a single operational service of specialized medical care for children and the basic principles of its functioning on the territory of the Russian Federation are proposed.Methodology. Statistical data, features of legislation, ways of solving the problem in certain regions and the achievements of initiative groups of specialists are analyzed.Results and Discussion. Since 2000, the number of hospital beds for children, the number of emergency medical stations has decreased, and the number of diseases and conditions requiring specialized emergency care for children has increased. Infant mortality rates in remote and hard-to-reach regions exceed the national average by 1.5–2.6 times. At the same time, the current statistics of medical evacuations of children are not accurately reflected in any of the official sources. The regulatory framework for medical evacuation of children includes three “ Procedures for providing medical care “in the profile “ambulance”, “neonatology” and “obstetrics and gynecology” and Federal Law N 323. The law implies the presence of mobile teams in hospitals and departments of different profiles that are not related to each other, but there is no structure that unites them and analyzes the results of work at the federal level.Conclusion. To solve the problem, it is necessary to create a federal operational service and a “hotline” that can be contacted by any resident of the country, to form a federal medical register of critical conditions in children, to develop and implement common principles of diagnosis and treatment. The presented model and principles contribute to the development of a three-level system of emergency medical care and correspond to the goals and objectives of the Ministry of Health of the Russian Federation set out in Letter N 14-3/n/2-2339 of 20.03.2019.

Published: June 2021

Relevance. Currently, a significant number of approaches to the assessment of occupational risks as a result of exposure to harmful and dangerous factors of industrial activity are presented in the scientific, regulatory and legal literature. To assess occupational risks for the personnel of fire protection, risks of injury, morbidity, disability and mortality are calculated. However, no single method exists for calculating the integral index for final assessment of occupational health risk in personnel of Federal Fire Service (FFS) of EMERCOM of Russia.Intention: To develop a mathematical model for assessing occupational risks for fire protection units including workdays lost related to health disorders severity.Methodology. When developing a mathematical model for assessing occupational risks for the FPS of EMERCOM of Russia including workdays lost related to health disorders severity, risks to health and life of employees were directly assessed based on the following statistics (2015–2019): a) probability of hazardous situations; and b) the amount of health damage expressed as workdays lost. Coefficients of the health damage severity in the mathematical model are justified. For assessing rare occupational risks as well as in small groups, the continuity correction is proposed for injury and death risks.Results and Discussion. Various methods of assessing occupational risks for industrial activity are considered. The mathematical model for occupational risk assessment in the divisions of the FPS of EMERCOM of Russia based on workdays lost related to health disorders severity helps predict occupational risks to life and health. Occupational risks are calculated in terms of workdays lost related to health damage severity for employees of the FPS of EMERCOM of Russia for 2015–2019.Conclusion. Based on the mathematical model of occupational risks for the FPS of EMERCOM of Russia including workdays lost related to health disorders severity, specific occupational risks can be predicted for every specific workplace (position) in various regions of the Russian Federation.

Published: June 2021

:La diversidad étnico-cultural es una realidad que está presente en los centros educativos, y debe ser analizada y estudiada en profundidad. En esta realidad se generan grupos de mayorías y minorías, donde estos últimos suelen ser grupos vulnerables dadas sus características sociales y económicas. La evidencia científica avala que la inteligencia emocional y las competencias socioemocionales son factores protectores para el desarrollo del individuo, razón por la cual es necesario estudiar ambos factores teniendo en cuenta la diversidad étnico-cultural. El presente estudio pretende describir la diversidad étnico-cultural, la inteligencia emocional y las competencias socioemocionales en la Educación Secundaria en Andalucía. Para ello, se ha obtenido una muestra representativa de la Educación Secundaria Obligatoria en Andalucía (España), compuesta por 2,139 discentes. Como instrumento de recogida de datos se ha empleado la encuesta, empleando la versión española de la escala Trait Meta-Mood (TMMS) y el Cuestionario de Competencias Sociales y Emocionales (SEC-Q). Los resultados evidencian la presencia heterogénea en cuanto a diversidad étnico-cultural en la escuela andaluza con una mayor presencia de inmigrantes en las escuelas de la provincia de Almería. La inteligencia emocional percibida no presenta diferencias entre los grupos étnicos-culturales. Por el contrario, sí existen diferencias entre los grupos étnicos-culturales en el nivel de competencias socioemocionales del alumnado, concretamente en la autoconciencia. Esto revela la necesidad de promoción de dichas competencias en los escolares, teniendo en cuenta la diversidad del aula, apoyando la necesidad de impulsar la educación inclusiva.

The exhibition of two mummies in the Natural History cabinet in Paris aroused the interest of various scientific expeditions that made a stopover in Tenerife in the first half of the 19th century. Nicolas Baudin’s expedition in 1800 coincided with the discovery of a cave with mummies in El Sauzal and three ended up in the university museums of Montpellier and Göttingen and one in the cabinet of Saviñón. Another mummy was given to von Krusenstern’s Russian expedition of 1803, currently in the museum of Saint Petersburg. A new cave with mummies was discovered ca. 1815 in Tacoronte, which ended up in the scientific cabinet of Megliorini. Another mummy located in Valleseco, Santa Cruz, around 1823, was sold in Puerto de la Cruz to a Swiss merchant for the Geneva museum.

Published: June 2021

The article is devoted to the problems of the development of instrumental approaches to modeling of the municipal solid waste management system. A main purpose of the study is to develop a concept for joint accounting of the economic and environmental efficiency of the functioning of the municipal solid waste management system in the construction of economic and mathematical models. The generalization of world experience allows us to identify the insufficient elaboration of these issues. It allows also to determine the degree of limitations of existing approaches for the purposes of applied modeling of this area, as well as to identify their main strengths and weaknesses. In order to overcome these problems, a conceptual model of the functioning of the regional municipal solid waste management system has been developed, based on the synthesis of intersectoral and agency approaches. It is shown that it is promising for the further development of existing approaches to economic and mathematical modeling of this area in the direction of a more complete and simultaneous consideration of these aspects of efficiency, behavioral features and the main interrelationships of economic entities, as well as measures of state environmental policy.

Association between modified ankle-brachial pressure index and indices of adiposity
Authors: Ranjan Prabhat , Sarvottam Kumar , Yadav Umashree
Published: June 2021

Objectives:

Obesity is one of the important risk factors for peripheral arterial disease (PAD). Ankle-brachial pressure index (ABPI) is a non-invasive test, which may be used for earlier detection of PAD. ABPI in healthy obese/overweight subjects has not been studied. In present study, we investigated correlation of adiposity indices with ABPI. We have also compared ABPI by three different methods in healthy obese/overweight subjects.

Materials and Methods:

Weight, height, body mass index (BMI), waist circumference, hip circumference (HC), waist height ratio, waist hip ratio, skin fold thickness, and body fat percentage were measured in 45 healthy overweight/obese males. Ankle and brachial pressures were measured by Doppler ultrasound based method. ABPI was calculated using high ankle pressure (ABPI-HIGH), mean ankle pressure (ABPI-MEAN), and low ankle pressure (ABPI-LOW) methods.

Results:

BMI and HC show positive significant correlation with ABPI-LOW (P = 0.028, P = 0.046, respectively). Significant difference was observed between ABPI-LOW and ABPI-HIGH (P = 0.003). ABPI-MEAN and ABPILOW were also significantly different (P < 0.001).

Conclusion:

There is a correlation of obesity indices with ABPI-LOW. ABPI-LOW methods could be more appropriate method and contrastingly HC may have direct correlation with PAD detection by ABPI in apparently healthy obese.

The question of potential changes in CNF induced by phacosurgery remains poorly understood. The need for research in this direction is dictated by a number of circumstances: the introduction into clinical practice of confocal microscopy of the cornea, the need for phacosurgery against the background of changes in the cornea of various genesis, the possibility of the negative impact of laser radiation in the process of hybrid (femtolaser) phacoemulsification. Purpose. Assessment of changes in CNF after various methods of microinvasive phacosurgery. Material and methods. The studies were conducted in two groups of patients aged 50 to 60 years who underwent standard ultrasound and hybrid PV (30 operations each, respectively). The algorithm for assessing the state of the nerve fibers of the cornea included laser confocal microscopy using original software. To quantify the state of nerves, two coefficients were used: directivity anisotropy (K Δ L) and directivity symmetry (Ksym). Results. Regardless of the operation methodology, a tendency toward a decrease in the directivity anisotropy coefficient and an increase in the directivity symmetry coefficient, conditionally comparable with previously identified age-related changes in nerve fibers, was noted. After hybrid phacoemulsification, a decrease in the directivity anisotropy coefficient 2–2.5 months after the intervention turned out to be statistically less significant compared to the standard ultrasound technique. Further research should be aimed at analyzing the long-term results of both microinvasive phacosurgery techniques and the “classical” extracapsular cataract extraction, which still remains the method of choice in a number of clinical situations. Key words: corneal nerve fibers, phacosurgery, in vivo laser microscopy.

This article describes a clinical case of a filmy form of adenoviral epidemic keratoconjunctivitis (EKC) in an adult patient. The given case is interesting in that the onset of EKC did not foreshadow a complicated, hyperergic course of the filmy form in an adult patient. That ultimately led to cicatricial changes in the conjunctiva in the form of a partial external symblepharon. Alertness of ophthalmologists in relation to this form of EKC, which requires differential diagnosis, first of all, with true toxic diphtheria lesion of the conjunctiva, is necessary. Adequate complex antiviral treatment of EKC with the use of corticosteroids, immunomodulatory and symptomatic therapy helps to stop the process. Key words: adenovirus conjunctivitis, epidemic keratoconjunctivitis, membranous form, complicated course, partial simblefaron, dry eye syndrome.

O presente artigo tem como objetivo discutir aspectos da coletividade como unidade pedagógica na formação inicial do professor de matemática, em um processo de significação do conhecimento, pelos pressupostos da Teoria Histórico-Cultural. Compreendendo que a atividade coletiva está relacionada tanto aos processos de construção do conhecimento científico sistematizado e organizado pela escola, quanto nos processos de apropriação da cultura. Com isso, apresentamos, neste texto, reflexões acerca da coletividade na formação inicial de professores de matemática e uma síntese acerca da investigação realizada, por meio de ações formativas que desenvolvidas durante um ano letivo com um grupo de estudantes da Licenciatura em Matemática. A análise foi realizada por meio do método Materialista Histórico-Dialético, o que nos direcionou para a compreensão das unidades de análise: do movimento da história do conhecimento matemático; da busca pelo compartilhamento de significados; dos conflitos que mobilizam e transformam os sentidos por meio das experiências vivenciadas com o outro e a humanização do conhecimento científico, no cerne da atividade coletiva.

The brown Swiss breed of cattle, which is currently being bred in the Smolensk region for dairy and meat productivity, is of interest from the point of view of its production feasibility and competitiveness, and the biological properties of livestock. The research was carried out in a breeding reproducer for the breeding of brown Swiss cattle of the Smolensk region, in the conditions of the farm, the age of fruitful insemination, physiological development, linear affiliation and productive qualities were analyzed (n=384). According to the terms of fertilization, the animals were conditionally divided into three groups: - early-maturing 46 heads (12%) live weight of the first insemination 329 kg, medium-maturing 191 heads (49.7%) live weight 388 kg and late-maturing 147 heads (38.3%) live weight 429 kg. The genealogical structure of the analyzed livestock includes descendants of the related groups Meridian 90827 (46.3%), Concentrate 106157 (25.4%), Master 106902 (25.4%) and line Laird  71151 (2.9%). The highest milk yield and fat for the first (4520 kg) and highest lactation (5022 kg, 3.97 %) in late-maturing animals. The group of first-calf cows of medium precocity in terms of milk yield occupies an intermediate position (4334 kg). The difference in live weight between the third and first groups is significant (P<0.05). There were no significant differences in milk fat and protein between the groups of cows. From these studies, it follows that the larger the live weight at the first insemination, the more productive they are.

Published: June 2021

This paper focuses on the development of a concrete material by utilizing fly ash and blast furnace slag in conjunction with coarse and fine aggregates with an aim to reduce pollution and eliminate the use of energy extensive binding material like cement. Alternative binding materials have been tried with an aim to get rather an improved concrete material. Alkali-Activated Solution (AAS) made of the hydroxide and silicate solutions of sodium was adopted as the liquid binder whereas, Class F” fly ash and Ground Granulated Blast Furnace Slag (GGBFS) mixed in dry state were used as the Geopolymer Solid Binder (GSB). The liquid binder was used to synthesize the solid binder by thermal curing. The paper investigates the use, influence and relative quantities of the liquid and solid binders in the development of the alkali-activated GGBFS based Geopolymer Concrete (GPC). Varying ratios of AAS to GSB were taken to assess their optimum content. Further, different percentages of GGBFS were used as a partial replacement of Class F fly ash to determine the optimum replacement of GGBFS in the GPC. In order to assess their effects on various properties test samples of cubes, cylinders and beams were cast and tested at 3, 7, and 28 days. Thermal curing of GPC has also resorted for favorable results. It was found that AAS to GSB ratio of 0.5 and GGBFS content of 80% yielded the maximum strength with a little unfavorable effect on workability. The overall results indicated that AAS and GGBFS offer good geopolymer concrete which will find its applicability in water scarce areas. Doi: 10.28991/cej-2021-03091708 Full Text: PDF
