Abstract. Glacier surface mass balance observations in the Tien Shan and Pamir are relatively sparse and often discontinuous. Nevertheless, glaciers are one of the most important components of the high-mountain cryosphere in the region as they strongly influence water availability in the arid, continental and intensely populated downstream areas. This study provides reliable and continuous surface mass balance series for selected glaciers located in the Tien Shan and Pamir-Alay. By cross-validating the results of three independent methods, we reconstructed the mass balance of the three benchmark glaciers, Abramov, Golubin and Glacier no. 354 for the past 2 decades. By applying different approaches, it was possible to compensate for the limitations and shortcomings of each individual method. This study proposes the use of transient snow line observations throughout the melt season obtained from satellite optical imagery and terrestrial automatic cameras. By combining modelling with remotely acquired information on summer snow depletion, it was possible to infer glacier mass changes for unmeasured years. The model is initialized with daily temperature and precipitation data collected at automatic weather stations in the vicinity of the glacier or with adjusted data from climate reanalysis products. Multi-annual mass changes based on high-resolution digital elevation models and in situ glaciological surveys were used to validate the results for the investigated glaciers. Substantial surface mass loss was confirmed for the three studied glaciers by all three methods, ranging from −0.30 ± 0.19 to −0.41 ± 0.33 m w.e. yr−1 over the 2004–2016 period. Our results indicate that integration of snow line observations into mass balance modelling significantly narrows the uncertainty ranges of the estimates. Hence, this highlights the potential of the methodology for application to unmonitored glaciers at larger scales for which no direct measurements are available.

Abstract. Melt ponds occupy a large part of the Arctic sea ice in summer and strongly affect the radiative budget of the atmosphere–ice–ocean system. In this study, the melt pond reflectance is considered in the framework of radiative transfer theory. The melt pond is modeled as a plane-parallel layer of pure water upon a layer of sea ice (the pond bottom). We consider pond reflection as comprising Fresnel reflection by the water surface and multiple reflections between the pond surface and its bottom, which is assumed to be Lambertian. In order to give a description of how to find the pond bottom albedo, we investigate the inherent optical properties of sea ice. Using the Wentzel–Kramers–Brillouin approximation approach to light scattering by non-spherical particles (brine inclusions) and Mie solution for spherical particles (air bubbles), we conclude that the transport scattering coefficient in sea ice is a spectrally independent value. Then, within the two-stream approximation of the radiative transfer theory, we show that the under-pond ice spectral albedo is determined by two independent scalar values: the transport scattering coefficient and ice layer thickness. Given the pond depth and bottom albedo values, the bidirectional reflectance factor (BRF) and albedo of a pond can be calculated with analytical formulas. Thus, the main reflective properties of the melt pond, including their spectral dependence, are determined by only three independent parameters: pond depth z, ice layer thickness H, and transport scattering coefficient of ice σt.The effects of the incident conditions and the atmosphere state are examined. It is clearly shown that atmospheric correction is necessary even for in situ measurements. The atmospheric correction procedure has been used in the model verification. The optical model developed is verified with data from in situ measurements made during three field campaigns performed on landfast and pack ice in the Arctic. The measured pond albedo spectra were fitted with the modeled spectra by varying the pond parameters (z, H, and σt). The coincidence of the measured and fitted spectra demonstrates good performance of the model: it is able to reproduce the albedo spectrum in the visible range with RMSD that does not exceed 1.5 % for a wide variety of melt pond types observed in the Arctic.
Mapping snow depth at very high spatial resolution with RPAS photogrammetry
Authors: Redpath Todd A. N. , Sirguey Pascal , Cullen Nicolas J.
Published: June 2018

Abstract. Dynamic in time and space, seasonal snow represents a difficult target for ongoing in situ measurement and characterisation. Improved understanding and modelling of the seasonal snowpack requires mapping snow depth at fine spatial resolution. The potential of remotely piloted aircraft system (RPAS) photogrammetry to resolve spatial variability of snow depth is evaluated within an alpine catchment of the Pisa Range, New Zealand. Digital surface models (DSM) at 0.15 m spatial resolution in autumn (snow-free reference) winter (02/08/2016) and spring (10/09/2016) allowed mapping of snow depth via DSM differencing. The consistency and accuracy of the RPAS-derived surface was assessed by the propagation of check point residuals from the aero-triangulation of constituent DSMs, and via comparison of snow-free regions of the spring and autumn DSMs. The accuracy of RPAS-derived snow depth was validated with in situ snow probe measurements. Results for snow free areas between DSMs acquired in autumn and spring demonstrate repeatability, yet also reveal that elevation errors follow a distribution substantially departing from a normal distribution, symptomatic of the influence of DSM co-registration and terrain characteristics on vertical uncertainty. Error propagation saw snow depth mapped with an accuracy of ±0.08 m (90 % c.l.). This is lower than the characterization of uncertainties on snow-free areas (±0.13 m). Comparisons between RPAS and in situ snow depth measurements confirm this level of performance of RPAS photogrammetry, while also highlighting the influence of vegetation on snow depth uncertainty and bias. Semi-variogram analysis revealed that the RPAS outperformed systematic in situ measurements in resolving fine scale spatial variability. Despite limitations accompanying RPAS photogrammetry, which are relevant to similar applications of surface and volume change analysis, this study demonstrates a repeatable means of accurately mapping snow depth for an entire, yet relatively small, hydrological basin (~ 0.4 km2), at very high resolution. Resolving snowpack features associated with re-distribution and preferential accumulation and ablation, snow depth maps provide geostatistically robust insights into seasonal snow processes, with unprecedented detail. Such data will enhance understanding of physical processes controlling spatial distribution of seasonal snow, and their relative importance at varying spatial and temporal scales.

Dilthey and Darwin Combined? 19th Century Geisteswissenschaft for 21st Century Cultural Science
Authors: Herrmann-Pillath Carsten
Published: June 2018

This paper explores the relevance of Dilthey’s conceptualisation of the ‘Geisteswissenschaften’ (human sciences) for Cultural Science. In a nutshell, I argue that Cultural Science is Dilthey plus Darwin. In this effort, I define the Geisteswissenschaften as ‘performative sciences’: Taking economics as an example, I show that the Geisteswissenschaften are sciences which are ontologically productive in creating and performing the object of their research. That means, they are inherently normative since they entail critical reflexivity as a major mode of research. Following Dilthey, Geisteswissenschaften are deeply historical, which implies that their disciplinary structure is evolving together with their objects. Therefore, I argue that the 19th century division of disciplines needs to be thoroughly overhauled in the 21st century, including the division between economics and sociology, which is a left-over from 19th century nation-state development. New disciplines, with Cultural Science and Technosphere Science as prime examples, must be established to cope with the challenges of our times: where human agency, culture and technology have blurred long-established boundaries separating nature, culture and society; where identity and meaning have become global, fluid, contested and reflexive phenomena; and where nature (the environment) and culture (cities) are inextricably interrelated in the dynamics of the emergent Anthropocene system.

Las manifestaciones neuropsiquiátricas del lupus eritematoso sistémico (les) incluyen los síndromes neurológicos del sistema nervioso central (snc), periférico y autonómico, así como los síndromes psiquiátricos observados en los pacientes con les, una vez que se han descartado otras causas. La asociación entre miastenia gravis y otra enfermedad autoinmune fluctúa entre el 5 y el 30% de los casos. Se presenta el caso de una mujer de 29 años, de quien, después de múltiples ingresos hospitalarios y una serie de estudios por cuadros de debilidad, se pudo demostrar la relación entre miastenia gravis y el lupus eritematoso sistémico que ya padecía.CREA CIENCIA Vol. 11 No 1-2 ISSN 1818-202X enero-diciembre 2017, p. 82-85
Violencia armada como un grave problema de salud pública
Authors: Marquina de Reyes Ana Milena
Published: June 2018

En este ensayo se presenta el enfoque multifactorial de la violencia; no obstante, el autor se centró en la violencia armada que se ha vivido y se sigue viviendo en El Salvador. Para estudiar este fenómeno se procedió a analizar datos de violencia producida por armas de fuego, un tipo de violencia que casi siempre produce saldos mortales. La violencia armada es un fenómeno de gran impacto en la salud pública, como lo demuestra el indicador de los años de vida potencialmente perdidos (avpp), que informa acerca de las enfermedades o hechos violentos que producen muerte de manera prematura. Ha de hacerse notar que el término armas de fuego se refiere al instrumento que se usa para aumentar la violencia, llevando esto a la violencia armada. El impacto de la violencia puede evidenciarse por medio de indicadores como el gasto en salud, la esperanza de vida y la mortalidad, pero el más ilustrativo es la tasa de homicidios. Este problema tampoco se puede tratar únicamente por la vía del área de salud, por lo que también se discutió la regulación de las armas de fuego en El Salvador, que es otro aspecto importante.CREA CIENCIA Vol. 11 No 1-2 ISSN 1818-202X enero-diciembre 2017, p. 86-93
Linguistic Feature Analyses of Chinese Learners of English and Contributions of Discrete Features to Perceptual Judgment
Authors: Chen Hsueh Chu
Published: June 2018

This study (a) conducted a feature analysis of the spoken data of Chinese university students in pronunciation, grammar, and discourse, (b) investigated the contributions of the discrete linguistic features to the perceptual ratings on foreign accent, comprehensibility, delivery, and general language use. Ten university learners were selected from the Spoken Corpus of the English of Hong Kong and Mainland Chinese learners (http://corpus.ied.edu.hk/phonetics/), in which two speakers were paired up to conduct a five minutes interview. Three-level analyses were done to investigate Chinese learners’ linguistic features. Forty listeners from four L1 language backgrounds were recruited to rate the speech samples. The results show that strongly negative correlations were found between the production and perceptual rating scores for “omission of consonant(s) in final position” “redundant article ‘the’”, “silent pauses” and “discourse markers,” suggesting that the four features can be perceived and exert strong negative influences on perceptual judgments. Pronunciation rating had the strongest positive correlations with “foreign accentedness”; grammar rating had the strongest positive correlations with “general language use”; discourse rating had the strongest positive correlations with “general delivery”, and “general language use.” Regarding the rating of comprehensibility, “misuse of conjunctions” “redundant article ‘the’”, “silent pauses”, “lengthening”, and “stressing” showed strong negative correlations whereas “filled pauses” had strong positive correlations with it. Regarding the rating of foreign accentedness, strong negative correlations were found between “omission of consonant(s) in final position”, “lengthening”, “discourse markers”, and “stressing” and the rating of “foreign accentedness”.

Published: June 2018

Sweet potato is one of the most important staple crops in Sub-Sahara Africa because of its supply of carbohydrates, vitamin A and C, fiber, iron, potassium and protein.The objective of this study was to determine phenotypic variation in diverse sweetpotato varieties for marketable roots, fresh root yield, fresh biomass weight, harvest index, beta carotene content and root dry matter content. Twenty five sweet potato genotypes were evaluated at two sites in two seasons in Kenya using a randomized complete block design of three replications. The results indicated that there were highly significantly variations for genotypes and sites for all the traits studied. There were no significant differences for genotype x site x season effects for the traits except for the number of marketable roots and fresh root yield. The mean fresh root was 32.19 t/ha,with the genotype Ininda expressing the highest fresh root yield of 54.79 t/ha. Genotypes, Naspot 13, Ejumula, Kabode, Vitaa and Tio-Joe gave the highest beta carotene content ranging between 11.830 and 10.040 mg/100g; with a mean of 5.384 mg/100g. The mean root dry matter content was 24.84 % with clones Amelia and Melinda showing the highest and lowest root dry matter content of 30.62 and 16.52 % respectively. Ten genotypes including Ininda, Erica, Jane, Naspot 13, Ejumula, Kabode, Vitaa, Tio-Joe, Amelia and Mayai were recommended as potential parents for sweet potato breeding program in Kenya.

Hong Kong Cantopop
Authors: Chu Yiu-Wai
Published: June 2018

Cantopop, the most representative genre of Hong Kong popular music, is a major part of the popular cultural phenomenon of Hong Kong. Once the leading pop genre of Chinese popular music across the world, Cantopop has a history that needs to be written, which is especially important for the present and the future of Hong Kong, a city whose citizens have been witnessing the decline of not only its popular cultures but also core values. Toward this end this book aims to contribute the first full-length study of Hong Kong Cantopop in English. First, the book offers a critical account of the development of Hong Kong Cantopop in a readable style. Second, it is useful for refreshing English-speaking readers’ understanding of Cantopop and its cultural and social significance. Third, it provides insight into the issue of local culture widely discussed in the relevant debates in the field of cultural studies. This book shows how the rise of Cantopop is related to an upsurge of Hong Kong culture in general, and how its decline since the 1990s is connected to changes in the music industry as well as geopolitical landscape. As such, this book is not only a concise history of Cantopop but also of Hong Kong culture.
Fixing Inequality in Hong Kong
Authors: Wong Yue Chim Richard
Published: June 2018

When discussing inequality and poverty in Hong Kong, scholars and politicians often focus on the failures of government policy and push for an increase in social welfare. Richard Wong argues in Fixing Inequality in Hong Kong that universal retirement support, minimum wage, and standard hours of work are of limited effect in shrinking the inequality gap. By comparing Hong Kong with Singapore, he points out that Hong Kong needs a new and long-term strategy on human resource policy. He recommends more investment in education, focusing on early education and immigration policy reforms to attract highly educated and skilled people to join the workforce. In analyzing what causes inequality, this book ties disparate issues together into a coherent framework, such as Hong Kong’s aging population, lack of investment in human capital, and family breakdowns. Rising divorce rates among low-income households have worsened the housing shortage, driving rents and property prices upwards. Housing problems created a bigger gap between those who own housing and have the ability to invest in their children’s human capital and those who cannot, thus adversely impacting intergenerational upward mobility. This is the third of Richard Wong’s collections of articles on society and economy in Hong Kong. Diversity and Occasional Anarchy and Hong Kong Land for Hong Kong People, published by Hong Kong University Press in 2013 and 2015 respectively, discuss growing economic and social contradictions in Hong Kong and current housing problems and their solutions.
Frederick Engels, Social Reproduction, and the Problem of a Unitary Theory of Women’s Oppression
Authors: Blackledge Paul ,   Department of Philosophy, Florida State University
Published: June 2018

In this paper I argue that Frederick Engels’s The Origin of the Family, Private Property and the State remains a fundamental resource for anyone wanting to understand the oppression of women as a capitalist form. By re-examining the strengths and weaknesses of Engels’s historicisation of women’s oppression through the lens of the debates opened by second wave feminism, I argue that, once properly understood, we can overcome the limitations of Engels’s book to point to the kind of unitary theory of women’s oppression essential to a strategy adequate to the needs of the struggle for women’s liberation.

Este artigo se trata de uma pesquisa documental e bibliográfica, cuja proposta foi avaliar o impacto das políticas de fomento à leitura, o Programa Nacional de Incentivo à Leitura (PROLER) e a inclusão de alunos com deficiência visual nas unidades de ensino do município de Uberaba-MG a partir da busca e identificação de projetos relacionados ao PROLER em Projetos Políticos Pedagógicos (PPP) de dez escolas municipais de Uberaba e conhecer como se dá a participação das pessoas com deficiência visual nessas ações de incentivo à leitura. Entende-se que a compreensão da Inclusão precisa ser abordada como política pública, devendo nortear a construção e a compreensão histórica de seus avanços e entraves. Autores como Jambeiro, Borges e Barros (2006), Libâneo (2001), Mantoan (2006) e Vasconcellos (2000) foram utilizados como referencial teórico deste artigo. Como resultados, foram encontradas ações isoladas, ora sobre a inclusão por meio das tecnologias para o deficiente visual, ora sobre práticas de leitura por meio de experiências exitosas em pontos isolados. Os PPPs pesquisados mostraram ações de leitura sem a participação direta das ações do comitê Vale do Rio Grande, sediado por Uberaba. Ressalta-se a necessidade de maiores estudos para que a população, os gestores e demais órgãos públicos possam respeitar as diferenças e compreender as reais necessidades da pessoa com deficiência, garantindo assim sua autonomia nos diversos espaços da sociedade.   Palavras-chave: Deficiência Visual.

Interação fraternal quando um irmão tem síndrome de Down: Um estudo observacional
Authors: Almeida Bruna Rocha de , Pereira-Silva Nara Liana
Published: June 2018

A qualidade da interação entre irmãos tem sido investigada há mais de três décadas, entretanto, poucos estudos focalizam a díade irmão com síndrome de Down (SD) - irmão com desenvolvimento típico (DT), especialmente, no Brasil. Este estudo objetivou descrever a interação entre nove díades de irmãos, com idades entre quatro e 13 anos, tendo um deles a SD. Foram gravadas, nas residências das díades, 27 sessões de observação do comportamento, totalizando 216 minutos. A análise das interações focalizou conteúdo e qualidade dos episódios, bem como categorias comportamentais de comando e responsividade. As díades se envolveram, principalmente, em atividades lúdicas, de forma ‘Conjunta’, com ‘Amistosidade’ e ‘Sincronia’. As interações tiveram ‘Supervisão’, ‘Liderança’ e emissão de comportamentos de comando do irmão com DT. Pode-se afirmar que, nessas famílias, a interação fraternal é caracterizada pela assimetria de papéis e positividade, não sendo prejudicada pela presença do irmão com SD.

Published: June 2018

O Atendimento Educacional Especializado (AEE) é realizado nas Salas de Recursos Multifuncionais (SRM) que são equipadas com recursos da Tecnologia Assistiva (TA). Para o uso eficaz desses recursos faz-se necessário que o professor do AEE tenha conhecimentos prévios que subsidiem a sua utilização junto aos alunos com deficiência. Os objetivos deste estudo foram identificar o grau de satisfação do professor do AEE em relação a sua participação no processo que envolve o uso do recurso da TA; e a existência de parcerias com profissionais de outras áreas do conhecimento nesse processo. Participaram do estudo nove professoras de SRM todas com contato prévio com aluno com deficiência física (DF). Para a coleta de dados utilizou-se um questionário, constituído por três partes. Os resultados indicam que para o uso da TA junto ao aluno com DF a maioria das professoras mantém parceria com diferentes profissionais tais como fisioterapeutas, fonoaudiólogos e terapeutas ocupacionais. A falta de conhecimento e de capacitação continuada sobre recursos da TA, bem como a ausência de retorno por parte de alguns dos profissionais que mantém parceria são os principais motivos que impactam negativamente na satisfação em relação ao uso da TA. Os resultados deste estudo trazem subsídios para a compreensão de aspectos que podem melhorar a eficácia do uso da TA no contexto educacional. Além disso, suscitam reflexões sobre qual a maneira mais adequada de se efetivar parcerias colaborativas eficazes no âmbito educacional, as quais possam consequentemente, intensificar os seus benefícios para os alunos com deficiência.

Presented work shows results of synthesis and spectrophotometric researches on properties of meso-dinitrosubstituted derivatives of 5,15-diphenyl-β-octaalkylporphyrin nitroderivatives in comparison with 2,8,12,18,3,7,13,17-octaethylporphyrin and 2,3,7,8,12,13,17,18-octaethyl-5,15-dinitroporphyrin. The method of spectrophotometric titration with perchloric acid (for determining the basicity constant) and 1,8-diazabicyclo [5.4.0] undec-7-ene (DBU) was used in order to study the acid-base properties of porphyrins, namely to determine the acidity constant. The spectral characteristics of the ionized forms of 5,15-dinitro-10,20-diphenyl-3,7,13,17-tetramethyl-2,8,12,18-tetraethylporfin-F (I) and 5,15-dinitro-10,20-bis(4-nitrophenyl)-2,8,12,18-tetramethyl-3,7,13,17-tetraethylporphyrin (II) and the corresponding total constants of the acidic (pKa (I) = 6.00 and pKa (II) = 5.27) and the basic (pKb (I) = 19.78 and pKb (II) = 19.83) ionization were provided. The reaction of complexation of porphyrins with zinc acetate was studied by spectrophotometric method in pure acetonitrile and in mixed AN + DBU solvent. The influence of the degree of deformation of the tetrapyrrole macroring, the electronic effects of substituents and the acidity of the medium on the coordination and acid-base properties of porphyrins was analyzed. It was shown that the reactions of formation of metalloporphyrins with anionic porphyrin forms proceed with much higher rates compared to molecular ones, that is accompanied with a decrease in the energy parameters of the reaction. This is evidently due to the absence of energy costs for the deformation and cleaving N-H bonds of the reaction center, as well as the stronger polarization of the molecule, and as a consequence, the higher degree of solvation of anionic forms of porphyrins in the transition state. Thus, the determination of the conditions for the existence of dianionic forms of porphyrins gives grounds for the development of new sensor systems for the recognition and determination of the concentration of metal cations in liquid media due to a sharp increase in the rate of formation of metalloporphyrins in the presence of an organic base.Forcitation:Pukhovskaya S.G., Ivanova Yu.B., Erzunov D.A., Semeykin A.S., Syrbu S.A.

The problem of obtaining highly soluble and biologically active drugs is actual. One of the methods for solving this problem is the inclusion of carbohydrate residues into the structure of biologically active compounds. Ethyl ester of p-(N-α-D-glucopyranoside)aminobenzoic acid has been synthesized by condensation of benzocaine with glucose. The obtained product has been studied by means of NMR spectroscopy, high-performance liquid chromatography and elemental analysis. Comparative analysis of the lipophilic properties of benzocaine and its glycosylated analogue and a profile of the potential target-specific activity of the latter has also been carried out. According to high-performance liquid chromatography data the obtained product was a mixture of the initial benzocaine and its glycosylated analogue with a content of components of 30% and 68.5%, respectively. It was shown that the inclusion of glucose fragment into the structure of benzocaine led to the decrease in the value of the lipophilicity coefficient and the increase in its solubility in water. A significant difference in the solubility of benzocaine and its glycosylated analogue was proved by NMR data. It was used for their separation, i.e. benzocaine was removed from the mixture by dissolving in chloroform. Virtual screening was carried out and a profile of the potential bioactivity of glycosylated benzocaine was obtained. It has been noted that ethyl ester of p-(N-α-D-glucopyranoside)aminobenzoic acid would participate in the metabolism of carbohydrates, amino acids and lipids.Forcitation:Volkova T.G., Talanova I.O.

The home heating systems as well as the food industry require a high degree of water purification. In the aims of the increasing of the quality of technical and potable water the experiments on the determination of the rigidity of water have been carried out in the fourth districts of Kazan after the addition to the water samples of β-alanine and l-asparagine as the agents for the complex formation with calcium and magnesium salts. The obtained results showed that the chosen amino acids able to reduce the rigidity and increase the quality of waters in 1.10-1.22 time. The calculated heats of combustion and formation of complexes of calcium and magnesium with alanine and asparagine confirm the conducted experimental results on their stability. Such experimental results prompted us to calculate the heat of combustion (DсH°) and formation (DfH°) of complexes of calcium and magnesium with the mentioned above amino acids [Met(amino acid)2, DсH°, DfH° (kJ mol-1± 0.5 % , respectively), number of valence electrons (N-g)] in according to the scheme of thermochemical research. It has been suggested to introduce the above mentioned amino acids or synthesized on their base little peptides into sorption-filters at the water preparation process.Forcitation:Ovchinnikov V.V., Kulakov A.A.

Resume

For at kunne skelne mellem tiltag til lærerudvikling har Cochran-Smith og Lytle udviklet tre grundforståelser af forholdet mellem læreres viden og deres praksis. En af disse, Knowledge-of-practice, er udgangspunkt for artiklen, idet vi med Lektionsstudier eksemplificerer potentialerne ved at benytte tiltag inden for denne grundforståelse. I Japan benyttes lektionsstudier i alle fag, mens tiltaget i Vesten overvejende bruges i matematikfaget og med et fagdidaktisk fokus. Ud fra en case om lektionsstudier i danskfaget argumenterer vi for, at tiltag som lektionsstudier giver lærere mulighed for at udforske og løse problemstillinger i deres undervisningspraksis fra et samtidigt alment og fagdidaktisk perspektiv.

 

Abstract

To be able to differentiate between approaches to teachers’ professional development, Cochran-Smith and Lytle have developed three conceptions of the relationships between teachers’ knowledge and their practice. One of these, Knowledge-of-practice, is the basis for this article, as we use Lesson studies to exemplify the potentials of approaches within this conceptualization. In Japan, Lesson studies are used in all subjects, whereas in the West the approach predominantly is used in Mathematics and with a focus on pedagogical content knowledge. Based on a lesson study case in the subject of Danish, we argue that approaches as lesson study provide teachers the possibility to research and solve teaching problems with a focus simultaneously on pedagogical knowledge and pedagogical content knowledge.
RAZLIKE U ISPOLJAVANJU MAKSIMALNOG MOMENTA SILE NATKOLENE MUSKULATURE PRI RAZLIČITIM UGAONIM BRZINAMA KOD KARATISTA
Authors: Čokorilo Dejan
Published: June 2018

Osnovni cilj istraživanja je da se utvrde razlike u ispoljavanju maksimalnog momenta sile agonista i antagonista natkolenice, pri različitim ugaonim brzinama kod karatista različitog uzrasta i da se na osnovu tih vrijednosti izračunaju unilateralni (hamstring/kvadriceps) i bilateralni odnosi (lijeva/desna noga). Uz pomoć unilateralnih i bilateralnih odnosa se utvrđuje eventualna mišićna neravnoteža oko kolenog zgloba i između lijeve i desne noge. Nekolicina studija je pokazala da smanjen odnos u snazi zadnje i prednje lože je povezan sa povećanim brojem povreda donjih ekstremiteta, kao što su ruptura prednjih ukrštenih ligamenata, overus sindrom, povreda zadnje lože. Testiranje je izvođeno na izokinetičkom dinamometru i obuhvatalo je procjenu maksimalnog momenta sile mišića prednje i zadnje lože natkolenice, pri brzinama od 60°/s i 180°/s, pri koncentričnoj i ekscentričnoj kontrakciji. Uzorak je činilo 28 karatista, podjeljenih u tri uzrasta: kadetski, juniorski i seniorski. Rezultati istraživanja su pokazali da postoje statistički značajne razlike (p≤0,05) u varijablama maksimalnog ispoljavanja momenta sile ekstenzora i fleksora natkolenice koncentričnom i ekscentričnom kontrakcijom, pri različitim ugaonim brzinama kod svih uzrasta. Pri brzini od 180°/s vrijednosti maksimalnog momenta sile su manje. Što se tiče unilateralnog odnosa postoje statistički značajne razlike pri različitim brzinama, kod svih uzrasta. Veće vrijednosti su dobijene pri brzini od 180°/s. Između bilateralnih odnosa nema statistički značajanih razlika pri različitim brzinama kod svih uzrasta. Vrijednosti unilateralnog odnosa kod ove grupe karatista su u rasponu od 50% do 80% , što ih prema tom kriterijumu ne svrstava u grupu sportista sa povećanim rizikom. Sa druge strane vrijednosti bilateralnog odnosa u nekim uzrastima prelaze granicu od 10%, koja je uzeta kao referentna, pa se njima preporučuje da preuzmu određene mjere kako bi se to ispravilo.

Published: June 2018

Cilj ovog rada je da se utvrdi stanje uhranjenosti kod dece školskog uzrasta starosti od 10 godina u odnosu na nivo njihove fizičke aktivnosti. Prevalenca prekomerne telesne mase i gojaznosti među decom je u porastu u mnogim zemljama sveta, pa i u Srbiji. Prema podacima Instituta za javno zdravlje Srbije „Dr Milan Jovanović-Batut“, u Srbiji je umereno gojazno i gojazno oko 18% mladih. Kao dva najvažnija uzroka gojaznosti kod dece i adolescenata, smatraju se pogrešan način ishrane i nedovoljna fizička aktivnost. Kako je zdravlje mladih u svakoj zajednici značajno ne samo sa medicinskog gledišta, već i za ekonomsku, socijalnu i demografsku budućnost svake zemlje, to se unapređenju zdravlja mladih kroz zdrav način ishrane i redovnu fizičku aktivnost mora posvetiti posebna pažnja. Rezultati dobijeni ovim istraživanjem dovode do zaključka da je jedna trećina od ispitivanog uzorka dece neodgovarajuće ishranjena, a da čak 20% dece ima prekomernu telesnu masu i gojaznost.

Published: June 2018

U ovom radu je obrađena povreda ramenog zgloba u sportu sa posebnim osvrtom na luksaciju humeroskapularnog zgloba. Nabrojani su najčešći sportovi kod koji se javlja ovakva vrsta povreda. Opisana je anatomija ovog zgloba, pato -anatomsko oštećnje koje nastaje nakon povrede, simptomatologija, dijagnostika i terapija kroz konzeravativno operativni pristup. Potrebno je napomenuti da nepotpuno odnosno nesanirani proces dovodi do vraćanja povrede a time do produžetka liječenja i do dužeg odsustvovanja sa sportskih borilišta a u pojedinim slučajevima uzrokuje prekid sportske karijere. Zbog toga je neophodno ozbiljan pristup liječenju ove povrede i da samo potpuno sanirana povreda dozvoljava sportisti da nastavi bavljenje sportom.

Cilj rada bio je da se ispitaju vrijednosti parametara inkubacije(gubitak mase, oplođenost, valivost uloženih i oplođenih jaja, te ukupan, rani,srednji i kasni embrionalni mortalitet) rasplodnih jaja različite mase teškog linijskoghibrida Cobb 500. Ukupno je ispitano 600 jaja podijeljenih u četiri jednake grupe(n=150) prema njihovoj masi: 57,5 – 62,5 (S); 62,6 – 67,5 (M); 67,6 – 72,5 (L) i 72,6 –77,50 g (XL), a vrijednosti parametara inkubacije određene su i statistički obrađenestandardnim metodama. Masa jaja uticala je statistički značajno na gubitak masejaja tokom inkubacije (p<0,05), pri čemu je taj gubitak bio veći kod jaja manje (grupaS 11,10% i grupa M 11,40%) u odnosu na jaja veće mase (grupa L 10,42% i grupaXL 10,31%). Valivost uloženih jaja u grupama S, M, L i XL iznosila je 76,0; 75,3;78,7 i 66,0%, redom, a oplođenih 82,0; 81,3; 82,5 i 71,7%, redom, pri čemu nijeustanovljena statistički značajna razlika (p>0,05). Masa jaja nije statistički značajnouticala na razliku u vrijednostima mortaliteta embriona, iako je kod jaja grupe XLustanovljena viša vrijednost ukupnog, ranog i kasnog mortaliteta u odnosu na ostalegrupe jaja. Rezultati ovog istraživanja ukazuju na niže vrijednosti valivosti i višimortalitet embriona u inkubaciji jaja izrazito velike mase u odnosu na ostale grupe,zbog čega izboru jaja za nasad treba posvetiti posebnu pažnju i u pogledu mase.

Odgovornost svih subjekata u poslovanju hranom je prevencijauslova koji mogu dovesti do razvoja i širenja bolesti prenosivih hranom. Sistem analizeopasnosti i kritičnih kontrolnih tačaka HACCP (Hazard Analysis Critical ControlPoints) izdvojio se kao najefikasniji standardizovani pristup kojim se smanjuju rizicipo bezbednost hrane i preporučen je od strane FAO (Food and Agriculture Organization)i WHO (World Health Organization). Dezinfekcija, dezinsekcija i deratizacija(DDD) su samo jedan od preduslovnih programa mera kod primene HACCP sistemau prehrambenoj industriji. Realizacijom ovih mera proizvođači su bliži svom krajnjemcilju, a to je bezbedan proizvod visokog kvaliteta. Mere dezinfekcije, dezinsekcijei deratizacije sprovode se kontinuirano i podrazumevaju složene, pažljivo planiranei celovite postupke uništavanja mikroorganizama, insekata i glodara. Ove merezahtevaju kombinaciju preventivnih i kurativnih mera i moraju se programskisprovoditi u cilju postizanja očekivanih efekata. Kompanije koje implementirajumere DDD-a moraju imati obučene izvođače koji razumeju principe HACCP-a iznaju kako primeniti mere DDD na način koji neće predstavljati rizik za krajnjegpotrošača.
