School bag weight and the occurrence of back pain among elementary school children
No full textBackground: Children in primary schools use school bags to carry study material, although the heavy bags are often associated with musculoskeletal problems, especially back pain. This practice requires strength, which significantly changes the body posture and walking pattern, subsequently leading to the incidence of back pain as a side effect. The aim of this study, therefore, is to analyze the differences in bag loads between elementary school children in urban and suburban area, and also analyze the relationship with the occurrence of back pain. Design and methods: This was a cross sectional study, which used stratified random sampling to choose 2 elementary schools each representing the urban and suburban areas. Furthermore, a total sample of 164 students were selected, whose school bag weight were measured for 5 consecutive days, particularly in the morning on respondents arrival at school. Moreover, the occurrence of back pain was evaluated using a modified Nordic map, and data analysis required the use of independent sample analysis t test and χ2 test.Results: The results showed the presence of highly significant differences in the school bags weight of respondents in the urban and suburban areas, as well as between schools using the 2013 curriculum and otherwise. Conclusions: In conclusion, there is a correlation between the weight measured and the occurrence of back pain, hence the 2013 curriculum is recommended to be adopted by all elementary schools. Also, the use of lockers to store items used at school repeatedly by children is also highly encouraged

Modeling the Number of Cases of Tuberculosis Sensitive Drugs (TBSD) in East Java using Geographically Weighted Poisson Regression (GWPR)
No full textTuberculosis lungs attacked the most productive age group (15-50 years), social economy is weak and low education. Estimated a patient Tb adult will lose the average time it works 3-4 months. This resulted in the loss of annual revenue run their house around 20-30%. In addition to harm economically, TB also provides other negative impact socially, even excluded by the community. In this research will be discussed about the factors that were supposed to afect many cases for TBSD which occurred in East Java with Poisson regression. but because they found the existence of the case of overdispersi so that need to pay attention to the factors location from the point of observation and used GWPR. From the results of the analysis and discussion, obtained the result that GWPR model more appropriate to analyze the patients TbSD in East Java because it has smaller AIC value. The dominant factor in influencing TBSD in all districts in East Java is the percentage of poor families (X1), except in Ngawi district and Magetan. For bTA+ (X2), the number of HIV/AIDS (X3), numbers genesis diabetes mellitus (X4), the percentage of the population density (X5) and rasio health workers (X6) affect TBSD patients in 7 groups of districts in East Java

The Pronunciation of Hebrew in the Western Sephardic Settlements (16th-20th Centuries). Second Part: The Pronunciation of the Consonant <i>‘Ayin</i>
No full textThe purpose of this investigation was to ascertain when the Italian Jewish communities and the Western Portuguese “Nations” adopted the nasal-guttural pronunciation of the ‘ayin, variously represented as gn, ng, ngh, hg. In 16th century Ferrara and Venice, the phonetic value of this consonant was zero or close to zero. Only at the very end of the 16th century, some authors in Italy graphically represented it as ng. In the same period, an Amsterdam author introduced new graphemes and expressed the ‘ayin as gh or hg, while a Hamburg scholar published a grammar-book where he gave the name of this consonant as Hgain. The new graphemes were not adopted by the majority of authors, who continued to represent it by a simple h, or left it without notation. Both in Italy and in Northern Europe, the h > gn shift was rather discontinuous.Estudio de la adopción de la pronunciación naso-gutural de la consonante ‘ayin y de su variada representación gráfica entre los judíos de Italia y de las «Naciones» judías hispano-portuguesas. Durante el siglo XVI, el valor fonético de esa consonante era o tendía a cero. A fines de ese siglo y a comienzos del XVII, algunos autores en Italia la representan como ng. Un autor coetáneo en Amsterdam introduce nuevos grafemas, tales como gh o hg, mientras que otro autor de Hamburgo publicaba una gramática en la que denomina Hgain esta consonante. Los nuevos grafemas no fueron adoptados por la mayoría de autores que continuaron representando dicha consonante por una h. Tanto en Italia como en el norte de Europa el cambio h > gn fue discontinuo
