AbstractPurpose. The aim of the study was to determine differences in anteroposterior spine curvatures between futsal players, soccer players, and non-training students. The results may contribute to the development of present-day knowledge of posturometry, and its implementation in training can help reduce the risk of body posture disorders in athletes. Methods. The examined group consisted of 48 athletes and 38 non-training college students. Body posture parameters were measured with the use of Posturometr-S. The normality of distribution was checked with the Shapiro-Wilk test, and the differences between the groups were measured with ANOVA and the Bonferroni post-hoc test. The level of statistical significance was set at p < 0.05. Results. The analysis of angle values revealed the widest and most similar measurements in the group of futsal players and soccer players. The analysis of variance proved statistically significant differences between the soccer players and futsal players (p = 0.003). The difference between the soccer players and non-training students was statistically significant. The highest γ angular value was measured in non-training students, followed by futsal players and soccer players. The statistical analysis revealed significant differences between the non-training students and futsal players, as well as non-training students and soccer players (p < 0.001). Conclusions. A complex assessment of athletes’ body posture is crucial in injury prevention. Training overloads may often lead to disorders of the organ of locomotion and affect the correct body posture in athletes. This, in turn, may result in pains and injuries.

Average Consumption

Based on the elements of statistical analysis on the dependence of fuel and lubricant consumption on tree diameter, it was assessed that with the increase of tree diameter, the fuel and lubricant consumption in the young oak and hornbeam stands decreases significantly, both in clear felling and in thinning and that the function form Y=exp(a+b x X?1) is the best description of the correlation The consumption of fuel compared to lubricant consumption is almost double, which agrees with the results of the previous studies. Average consumption of fuel and lubricant is 17.43 mL x tree?1, on the plots 20.27 mL x tree?1, average consumption of lubricant per tree on skid roads is 9.4 mL x tree?1, on the plots 11 mL x tree?1. The higher consumption of fuel and lubricant on the plots with selective thinning is the consequence of the longer time needed for the conversion per tree, compared to that in clear felling The consumption of fuel per unit area on the skid roads (clear felling) is 22.9 L x ha?1, on the plots (selective thinning) 7.6 L x ha?1. The consumption of lubricant on the skid roads is 13.3 L x ha?1, on the plots 4.29 L x ha?1. The higher consumption of fuel and lubricant per unit area on the skid roads is due to the difference in the number of trees per unit area Based on the results of the analysis of variance, it was found out that between fuel and lubricant consumption in selective thinning and in felling the trees along tractor skid roads there is no statistically significant difference at the level of significance of 95%. So, for practical purposes, the unique norms of consumption can be established for the stands similar to those in which the study was performed.

Problem Solvers

Life in the Anthropocene is characterized by many environmental problems, and, unfortunately, more continue to emerge. Although much effort is focused on identifying problems, this does not necessarily translate to solutions. This transcends to the training environment where students are often adept at understanding and dissecting problems but rarely are explicitly equipped with the skills and mindset to solve them. Here a group of undergraduate students and their instructors reflect on embracing the concept of becoming environmental problem solvers. We first identify themes associated with historical and contemporary environmental successes that emerged from our reading – or more specifically, we identify the recipe elements that underlie environmental success stories. Key elements of success involved setting clear objectives, identifying the scale of the problem, learning from failure, and consulting diverse knowledge sources. Next, we reflect on the skills and mindset that would best serve environmental problem solvers and enable future successes. Essential skills include innovative and critical thinking, ability to engage in collaborative teamwork, capacity to work across boundaries, and resilience. In terms of mindset, key attributes include the need for courage, enthusiasm and commitment, optimism, open mindedness, tenacity, and adaptability. We conclude with a brief discussion of ideas for revising training and curriculum to ensure that students are equipped with the aforementioned skills and mindset. The ideas shared here should contribute to ensuring that the next generation of learners have the ability to develop solutions that will work for the benefit of the environment, biodiversity, and humanity. Solving environmental problems will increasingly fall to the next generation so it is time to ensure that they are prepared for that task.

Metacognitive Reading Strategies

This study investigates EFL students’ metacognitive reading strategies awareness and their metacognitive reading strategies use. It also compares female and male EFL students in terms of their metacognitive reading strategies awareness and metacognitive reading strategies use. The quantitative research method is used through the survey research design. The study involves 53 undergraduate students, consisting of 33 females and 20 males. The data are collected by using a questionnaire of Metacognitive Awareness of Reading Strategy Inventory (MARSI-R inventory) developed by Mokhtari et al. (2018). The strategies on the MARSI-R inventory were scored on 1-5 scales. The data were analyzed through a simple calculation to find out the level of awareness of the students, and the statistical test of independent sample t-test were conducted to know the difference between females and males. The results show that all of the students possess high metacognitive reading strategies awareness, indicating high metacognitive reading strategies use. Despite there is a different level of awareness between female and male students, further analysis using an independent sample t-test shows that the level of awareness between the two is .742 (p0.05), meaning that the difference is not significant. The result of the research also shows that there are no significant differences in all subscales of metacognitive reading strategies use across gender. The p-value for global reading strategies is .224, for problem-solving strategies is .486, and for support reading strategies is .249. Thus, gender plays no role in determining the metacognitive reading strategies awareness and metacognitive reading strategies use.

The Difference

Heterogeneity of variance produces serious bias in conventional analysis of variance tests of significance when cell frequencies are unequal. Welch in 1938 and 1947 proposed an adjusted t test for the difference between two means when cell frequencies and population variances are both unequal. This article describes two ways to use the Welch t to evaluate the significance of the main effect for two treatments across k levels of a concomitant factor in a two-way design. Monte Carlo results document the bias in conventional analysis of variance tests and the stable and appropriately conservative results from applications of the Welch t to evaluation of treatment effects in the two-way design.

This study aims to assess hemoglobin (Hb) level difference according to characteristics and wheat flour consumption frequency among Indonesian aged ≥10. This study used national health survey (Riskesdas) 2013 data, involving 42,705 subjects in the analysis. Hb level was the dependent variable and the independent variables included sample characteristics and wheat flour consumption frequency. An independent t-test was used to examine the difference between two categories of variables and one-way analysis of variance for variables ≥3 categories. There were significant differences in Hb level within groups according to gender, age, education, working status, residence, region, wealth index quintile, and wheat flour consumption frequency. Hb level was significantly higher among subjects with consumption of ≥3 times/week (13,435 g/dL) than consumption of 3 times/month or never (13,357 g/dL). By having sex stratification, the highest Hb level was significantly found among those who consumed wheat flour ≥3 times/week, both in women (12,701 g/dL) and men (14,115 g/dL). There was no difference in Hb level according to wheat flour frequency consumption after stratifying the place of residence. By having wealth index quintile stratification, the significant difference was only found among subjects in quintile 2, it showed that Hb level was higher among subjects who consumed wheat flour 1-2 times/week (13,458 g/dL) than 3 times/month or never (13,299 g/dL). Hb level was lower among a group of female, younger age, lower education, unemployed, living in a rural area, living in the eastern region, quintile 1, and wheat flour consumption 3 times/month or never. Maintaining sustainable Fe fortification in wheat flour is important to reduce anemia.Keywords: anemia, iron fortification, wheat flour consumption  ABSTRAK Studi ini bertujuan untuk mengetahui perbedaan kadar hemoglobin (Hb) darah menurut karakteristik dan konsumsi tepung terigu penduduk ≥10 tahun. Studi ini menggunakan data survei kesehatan nasional (Riskesdas) 2013, dengan total sampel yang dianalisis dalam studi ini yaitu 42.705. Kadar Hb darah adalah variabel dependen dan variabel independen meliputi karakteristik dan frekuensi konsumsi tepung terigu sampel. Uji independent t-test digunakan untuk melihat perbedaan variabel dengan dua kategori dan uji one-way analysis of variance untuk variabel ≥3 kategori. Terdapat perbedaan kadar Hb darah yang signifikan antar kelompok menurut jenis kelamin, umur, pendidikan, status bekerja, tempat tinggal, region, kuintil indeks kepemilikan, dan frekuensi konsumsi tepung terigu. Penduduk yang mengonsumsi tepung terigu ≥3 kali/minggu (13,435 g/dL) secara signifikan memiliki kadar Hb darah lebih tinggi dibandingkan konsumsi 3 kali/bulan atau tidak pernah (13,357 g/dL). Setelah distratifikasi jenis kelamin, kadar Hb darah tertinggi secara signifikan pada penduduk dengan konsumsi tepung terigu ≥3 kali/minggu baik pada perempuan (12,701 g/dL) maupun laki-laki (14,115 g/dL). Tidak terdapat perbedaan kadar Hb darah menurut frekuensi konsumsi tepung terigu setelah distratifikasi tempat tinggal. Setelah distratifikasi kuintil indeks kepemilikan, perbedaan signifikan hanya terlihat pada penduduk di kuintil 2, yaitu kadar Hb darah lebih tinggi pada frekuensi konsumsi tepung terigu 1-2 kali/minggu (13,458 g/dL) dibandingkan konsumsi 3 kali/bulan atau tidak pernah (13,299 g/dL). Kadar Hb darah lebih rendah pada penduduk perempuan, umur lebih muda, pendidikan rendah, tidak bekerja, tinggal di pedesaan, tinggal di region Maluku Papua, dan mengonsumsi tepung terigu 3 kali per bulan/tidak pernah. Mempertahankan keberlanjutan fortifikasi Fe pada terigu berpotensi penting dalam menurunkan anemia.Kata kunci: anemia, fortifikasi Fe, konsumsi tepung terigu
