Published: February 2019

Objetivo: Investigar a confiabilidade e reprodutibilidade do aplicativo Jumpo® para medida de saltos verticais de lutadores.
Método: Participaram 16 atletas de ambos os sexos com idade média de 19 ± 5 anos, estatura de 1.7 ± 0.1 m, massa corporal de 65 ± 15 kg. A presente investigação contabilizou dois encontros, nos quais foram realizados teste-reteste de ambos os instrumentos de avaliações para os seguintes saltos verticais: Countermovement Jump, Squat Jump e Drop Jump, medidos simultaneamente com o Tapete de Contato e o Jumpo®. Foram analisados o tempo de contato com o solo e a altura máxima de salto. Para análise estatística foi aplicado coeficiente de correlação intraclasse destinado às avaliações intra e inter-avaliadores. Já os comparativos entre Jumpo® e tapete de contato foram utilizados novamente o coeficiente de correlação intraclasse   e a análise gráfica de Bland-Altman.
Resultados: Concordâncias “quase perfeitas” para altura máxima em todos os saltos, tanto intra-avaliadores (CCI= 0.911-0.959), como inter-avaliadores (CCI= 0.939-0.951) e inter-instrumentos (CCI= 0.939-0.972) foram encontradas. Porém, o tempo de solo não apresentou concordância significante inter-instrumentos (p<0.360). Entretanto, foram encontrados valores inter-avaliadores estatisticamente significativos (p<0.001).
Conclusão: O Jumpo® parece ser uma ferramenta válida e reprodutível para medida de altura máxima de saltos verticais, mas não para o tempo de contato com o solo. Sugere-se, portanto, que treinadores e técnicos podem ser encorajados a utilizar esta ferramenta para avaliação e monitoramento do desempenho de saltos em lutadores.

Published: February 2019

En Argentina se han sancionado dos leyes que, vinculadas, constituyen un nuevo paradigma a la hora de concebir políticas con respecto a la vida sexual y reproductiva de las personas (Ley 25.673 Ley 26.150). En este artículo se analiza uno de los principales puntos que se abordan a través de esta legislación: el acceso a la información a través de conocimientos pertinentes, precisos, confiables y actualizados sobre los distintos aspectos involucrados en la educación sexual integral, tanto por parte de establecimientos educativos como también por medio de las Tecnologías de la Información y la Comunicación (TIC). La revisión bibligráfica realizada permitió detectar que los establecimientos educativos encuentran ciertos impedimentos a la hora de enseñar lo diverso que implica la temática de sexualidad. Las TIC se han transformado en un instrumento privilegiado y las redes sociales en el ámbito propicio para acceder a información acerca de la sexualidad.

Authors: Hamdy Rasha , Halim Amal
Published: February 2019

Background: Egyptian hospital–based statistics showed that head & neck carcinomas represent 18% of all cancers and mostly diagnosed at advanced stages. Our Clinical Oncology & Nuclear Medicine Department of Mansoura Faculty of Medicine serves a large rural area of the Delta region of Egypt. There is no previous study in our institution that focused on oral tongue carcinoma alone. This study aims in establishing the demographics, treatment outcome and prognostic factors of oral tongue squamous cell carcinoma (SCC). Methods: We retrospectively reviewed data of 50 cases with oral tongue SCC treated in our department from January 2014 to December 2016 to evaluate the demography, pathological characteristics, and therapeutic modalities. We estimated the survival rates during the entire follow-up period by the Kaplan–Meier method. The univariate and multivariate Cox proportional hazards analysis were performed for prognostic factors determination. Results: The median follow-up was 30 months (range: 4-45 months). The 3-year overall survival (OS) and disease-free survival (DFS) rates were 68% and 60% respectively. By univariate analysis, both advanced stages (III, IVA) and depth of invasion >0.5 cm were statistically significant as prognostic factors for 3-year DFS and OS rates. DFS rates were 34% vs. 98% for stage III and IVA vs. stage I and II respectively (p = 0.001); 52% vs. 78% for >0.5 cm vs. ≤0.5 cm depth of invasion (p = 0.003). OS rates were 36% vs. 99% for stage III and IVA vs. stage I and II respectively (p = 0.002); 52% vs. 80% for >0.5 cm vs. ≤0.5 cm depth of invasion (p = 0.001). Multivariate analysis of prognostic factors affecting 3-year DFS and OS rates confirmed the statistical significance of the same 2 factors. Conclusions: The majority of our patients were males below 60 years. Tumors were mainly found at stage III and were moderately differentiated. Vascular invasion and lymphatic permeation were uncommon. Staging and tumor invasion depth significantly affected the outcome. The 3-year OS and DFS were 68% and 60% respectively.

Background: There are no data of efficacy comparison between primary systemic therapy in stage 3B and 4 breast cancer patients in Indonesia. This study compared long term outcomes of breast cancer patients treated with neoadjuvant hormonal therapy (NAHT) and those treated with neoadjuvant chemotherapy (NACT)Methods: This was a cohort study conducted from 2011 to 2017. A total of 122 patients with stage 3B and 4 breast cancer received NAHT (n = 62) or NACT (n = 60) within a 6 cycles for NACT and 6 months for NAHT were included. Patients were excluded if they had a mastectomy before treatment, were pregnant, had been given hormonal therapy or chemotherapy before, had a contra-indication of chemotherapy, had a contra-indication of salpingo-oophorectomy bilateral for premenopausal patients, and declined to enter this study. The primary outcome of this study was overall survival. The outcomes were analysed using Kaplan-Meier for survival analysis and cox proportional hazard regression to estimate the hazard ratio.Results: There was a statistically significant difference in overall survival (p = 0.038). Median overall survival for NAHT patients was 1265 days and for NACT patients was 654 days. The hazard ratio showed NACT patients had a higher risk than NAHT patients (1.7 95% CI 1.03 – 2.9). Pathological complete response rate was higher in the NACT group than in the NAHT group (3.3% vs. 0%).Conclusions: Neoadjuvant hormonal therapy was superior to neoadjuvant chemotherapy in term of overall survival.

Published: February 2019

Background: Cervical cancer and breast cancer are the two top leading cases of female cancer in Indonesia. Being the 2nd largest city in Indonesia, Surabaya is being populated by more than 1.5 million females in 2017. This study aimed to describe the demographic characteristic of women living with cervical and breast cancer in order to show the current picture of female cancer situation in Surabayan communities nowadays. Substantial to it, the correlation between time of first diagnosis and type of therapy with current stage of cancer were analyzed to evaluate the cancer management effectiveness in community context.Methods: This cross-sectional study involved six (9.68%) Public Health Centers (PHCs) among 62 PHCs in Surabaya, Indonesia, which were selected by one stage cluster random sampling. There were 140 and 139 women living with cervical and breast cancer participated in this study respectively (n=279). Self-developed demographic questionnaire was used to collect the data. Descriptive statistic, Spearman Rank correlation test, and Mann-Whitney U test were used in data analysis (α<.05).Results: Overall, most respondents were married (77.06%) and were housewives (59.14%). They were high school graduated at majority (44.44%). Family support came from spouse and children (70.25%). Those with breast cancer mostly aged middle-up adulthood (56.12%), while older aged were found in respondents with cervical cancer (72.86%). The majority had been diagnosed with cancer for less than five years (81.36%), but there was a tendency that the longer life expectancy was found in those with cervical cancer. More cervical cancer respondents with advanced stage were found to be long-term survivors (25%). The first time of diagnosis and the type of therapy were significantly different between cases (p=.039 and p=.000 respectively), but the current stage of cancer was not significantly different (p=.239). There was a quite strong correlation between time of first diagnosis and current stage of cancer (ρ = -.409; p=.000), but there was no significant correlation between type of therapy and current stage of cancer (p=.147).Conclusions: The demographic characteristic of women living with cervical and breast cancer has been slowly shifting from elderly or late adulthood, to middle and early adulthood. The first time of diagnosis and the type of therapy were significantly different between cases, but the current stage of cancer was not significantly different. There was a strong significant correlation between time of first diagnosis and current stage of cancer in cervical and breast cancer.

Population process in dynamic development ongoing in Murmansk Region (located beyond the Arctic Circle on the territory of the European part of the Russian Federation Arctic zone in the period 2001-2015 has been characterized in the paper. Major features of natural population movement (fertility, mortality) including labor potential have been esteemed. A major loss of labor potential was due to population decline (22,4 %), despite positive increase in 1.38 times of the total fertility rate and life expectancy among men up to 64,0 years, women - 75,7 years. It is shown that mortality increase was registered in the region among males of working age from disease that could be connected not only with Arctic climate and geographic conditions but also with labor conditions on industrial complex production of Kola Arctic Circle. The rate of diseases of respiratory and circulatory systems as well as malignant neoplasms increased in monotowns in Murmansk Region. 93 % of population is urban, which is a source of labor for city forming enterprise.

The data analysis presented in the studies of leading Russian and foreign centers on physico-chemical, molecular and biological, cytological and toxicological characteristics of nanosized powder blue has been done. Generalization of the information received and evaluation of potentially hazardous substances has shown that nanodispersed powder blue has a high degree of potential danger to human health. Powder blue nanoparticles have a size in the range of 41.2-77.9 nm, preferably of spherical shape, are hydrophobical, potentially high reactive. They have the ability to intracellular generation of reactive oxygen species causing the oxidative stress (particularly oxidative damage to proteins and indirect damage to DNA). They are able to DNA direct damage, having a dose and time-dependent character. They interact with the cell membrane, causing it damage (cytotoxicity), as evidenced by the decrease in mitochondrial activity, LDH release from cells, and fall of cells viability. A significant induction of chromosome aberrations is typical for powder blue nanoparticles. They cause a disturbance in proteomic and metabolomic profile, increase antioxidant enzyme of gene expression of HO-1, the production of cytokines MCP-1 and IL-8. They have possibly carcinogenic activity to humans, due to an increase in the level of intracellular reactive oxygen species formation, signaling cascades, damage to macromolecules - proteins and DNA.

The aim of the study was to assess the state of endothelial function in conditions of in the work, individual biochemical (homocysteine, folate, vitamin B12 levels) and functional (by peripheral arterial tonometry) markers of endothelial dysfunction during a marine trans-latitude voyage in the Arctic were studied. The design of the study is a prospective cohort nonrandomized study. The object of the study was practically healthy people - members of the Arctic scientific expedition and crew members of the marine scientific research vessel. The preliminary analysis of the obtained data allows to state that in healthy participants of short-term transhort maritime voyage in the Arctic abnormalities of endothelium-dependent vasodilation function were detected using the method of peripheral arterial tonometry on EndoPaT-2000 device with a test with active hyperemia and homocysteine exchange results, which indicates the presence of endothelial dysfunction. The unfavorable influence of high latitudes of the Arctic on the formation of endothelial dysfunction in healthy participants of the expedition and members of the research vessel crew was revealed.

Objective. The main goal of this article is to estimate an influence of thermal wave on population mortality of Krasnoyarsk city. Methods. The temperature waves' identification was carried out by method of long-term classification of mean daily temperature. To define relative mortality increase during thermal wave over background mortality a relative risk (RR) was revealed and calculated as maximum of RR values in different lags from 0 to maximal acceptable lags. Results. Daily mortality of Krasnoyarsk population has been studied for 10 years. The indices were divided into four age groups (0-17, 18-29, 30-64 and 65 years and older). Three groups that caused mortality have been marked: circulatory diseases, diseases of respiratory system and external causes. To assess the proportion of the population exposed to the influence of temperature waves a relative risk (RR or RR) was calculated. To compare the population mortality risk from thermal waves with other risks expectance of thermal waves' rising, death expectance during the thermal waves and the risk of mortality increase from thermal waves were calculated. Conclusions. The study results allow to state that the thermal waves (both heat and cold) have a greater negative effect on death from circulatory diseases in the age group 65+, with the risk magnitude from heat waves 4,4 ∙ 10-3 and from cold - 4,81 ∙ 10-3.

The results of longitudinal study on influence of education in middle and late adulthood on cognitive processing are analyzed in the article. The research has been conducted since the October 2014 and 21 persons aged 51-63 participate in it. All participants are the students of the program for professional retraining in "Practical Psychology". The duration of the program is 2.5 years. All participants are pensioners university-educated in different spheres (engineering, economy, teaching etc.) and did not work at the beginning of the program. Learning psychology was a new sphere for all of them and this was a key point for the research. Characteristics of cognitive processes were measured every two months along with person's psychological status and the level of psychological comfort. The study has found that the education in middle and late adulthood led to positive changing in cognitive sphere and increase in subjective well-being indices. Statistically significant changes were observed since the second term of learning. The participants re-imagined their own cognitive functioning; they considered that their memory, attention, efficiency and cognitive awareness became more effective while objective data did not confirm the latter. Substantial improvement in cognitive functioning became observable only at the end of the second term after half - year training. So, the study demonstrated possibility to change psychological status and cognitive functioning of middle aged and elderly people during acquirement.
Efficiency of agricultural production in Hungary
Authors: Bozsik Norbert , Magda Róbert
Published: February 2019

Purpose – The object of the article is to evaluate the efficiency of agricultural production in Hungary and in Hungarian regions. Furthermore, our purpose is to point out the effectiveness of Hungarian agriculture compared to the average of the EU. Based on results we evaluate the regional differences from the aspect of agricultural productivity and Hungary’s lag behind the average level of EU member states. Design/methodology/approach – The methodology of the paper is based on partial productivity methods. Comparing the main economic indicators of agricultural industry (output, gross value added and enterpreneurial income) to the annual working unit (AWU) and land unit (hectare) we analysed how efficiently labour and land is used in production. Conclusions are drawn from the results of the analysis. Findings – The paper shows the main charasteristics of Hungarian agriculture. Based on measuring efficiency of agricultural production, we highlight the extent to which the efficiency of Hungarian agricultural production remains below the EU average. The article also presents how effective the production factors (labour and land) are in the agricultural production of the regions of Hungary. Research limitations/implications – In the paper, we applied partial efficiency methods to evaluate the productivity of agricultural production. There are several directions of further investigations to measure the efficiency of agriculture (e.g. multi-factor productivity methods). Beside the methods, the research can be extended for any other direction (e.g. any other NUTS level etc.). Practical implications - Based on the results we outline recommendations for more effective use of production factors. The proposals are concerning how to increase the efficiency of the workforce in agriculture and to the find the optimal land utilization considering the environmental sustainability. Originality/Value – The paper provides comprehensive view on Hungarian agriculture situation with special emphasis on the regions. It presents original results of efficiency of the Hungarian agricultural production by regions and draws proper conclusions for practice. Keywords: agricultural production, efficiency, labour market, land market. Research type: research paper.

A Woman's Novel: Olive Schreiner, Mona Caird, and Hélène Cixous'sÉcriture Féminine
Authors: Cano Marina
Published: February 2019

In the 1880s and 1890s, New Woman writers changed the face of British society and British fiction through their sexually open works, which critiqued old notions of marriage, and through their stylistic experimentation, which announced the modernist novel. New Woman scholarship has often studied their work in connection with that of French feminists of the late twentieth century, such as Julia Kristeva, Luce Irigaray, and Hélène Cixous. This article reconsiders the nature of this connection through a close examination of novels by two of the most popular New Woman authors, Mona Caird (1854–1932) and Olive Schreiner (1855–1920). I read Caird's The Wing of Azrael (1889) and Schreiner's The Story of an African Farm (1883) through the lens of Hélène Cixous's theories of écriture féminine, or feminine writing, to question the accusation of biological determinism which is frequently directed at both groups of writers. By applying Cixous's notions of feminine aesthetics, bisexuality, and alterity to Caird and Schreiner, my study provides the basis for a new understanding of their novels. More generally, it complements and qualifies the connection between the New Woman and so-called French feminism, thereby helping produce a more complex framework to study the fin de siècle.
Tecnologías de la comunicación y emocionalidad en familias transnacionales
Authors: Ramírez Contreras María Guadalupe
Published: February 2019

En 2009, la estimación de migrantes mexicanos en Estados Unidos era 11,500.0 millones (Centro Hispánico Pew, 2009). Dichos migrantes no siempre llevan a su familia con ellos. Ante esta separación, las familias transnacionales intentan compensar la ruptura con una cercanía emocional, a través del uso de las tecnologías de comunicación. Sin embargo ¿qué tipo de apoyo emocional se da cuando un familiar de la tercera edad padece una enfermedad crónica? ¿Cómo viven la emocionalidad dichas familias transnacionales? ¿Qué tecnologías utilizan para comunicarse? y ¿Cómo se relaciona la comunicación con el apoyo emocional? Para dar respuestas busqué cubrir las carencias de estudios previos, en los que sólo incluían la perspectiva de los migrantes e incluí el punto de vista de todos los miembros de las familias. Llevé a cabo un estudio cualitativo al occidente de México. Entrevisté a diferentes miembros de 15 familias transnacionales durante el año 2012 y 2013.  Los resultados mostraron que el apoyo emocional en las familias consistía en: a) el establecimiento de la comunicación iniciado por los migrantes, b) el intercambio de vivencias del día a día; c) la resolución de problemas o conflictos; y d) el acompañamiento, participación o presencia del migrante en fechas especiales. Los migrantes utilizaron las tecnologías de comunicación para mantener vínculos afectivos y dar apoyo emocional a sus padres. Dichas tecnologías también les permitieron manifestar soledad y nostalgia. Recomiendo estudiar a los migrantes nacionales y a las poblaciones rurales, para analizar si existen diferencias con las poblaciones de mi estudio.
