Study of steepening, flattening, clockwise, and counter-clockwise torque effect is indispensable to understand and design surgical induced astigmatism calculator. Hence, in this study by constructing a novel Microsoft Office Excel 2007 based astigmatic calculator following cataract surgery, analysis on the accuracy and predictability evaluated for the performance. Post-cataract surgery patients from May 2019 to January 2020 at a tertiary medical institution recruited for this present study. Based on Pythagoras principle, MS Excel calculator designed and the law of cousins for calculating the vector magnitude and axis respectively. Manual keratometry measurements for pre and postoperative horizontal (Kh) and vertical (Kv) curvatures established, and statistical analysis for the resultant SIA magnitude and axis deduced with Medcalc software comparing with the existing SIA 2.1 version calculator. A total of 29 eyes of 25 patients studied with a mean age of 62.55 (±8.08) years, males contributing to 14 (56%), and right laterally in 17 (58%) eyes. MS Excel and SIA 2.1 versions calculated a mean SIA magnitude of 0.66 (±0.47) D and 0.64 (±0.55) D respectively. Pearson coefficient correlation (r=-0.16, p=0.40), paired-two sample test (t value= 0.11, p= 0.91) and ROC curve analysis (AUC = 0.75, p= 0.34, 95% CI= 0.25 to 0.99) calculated. Regression equation (y = 0.75 + -0.14 x) and limits of agreements (95% CI -0.29 to 0.31) analyzed, and, 95% of data points distributed within ±1.96 SD of the line of equality on Bland-Altman difference plots.The present calculator proclaimed an acceptable accuracy and agreement with a prediction of 0.61 Diopter for every unit change in the magnitude of SIA 2.1 software in addition to consideration of interchangeability.

We show that a straightforward modification of a trading-based test for predictability displays interesting advantages over the Excess Profitability (EP) test proposed by Anatolyev and Gerco when testing the Driftless Random Walk Hypothesis. Our statistic is called the Straightforward Excess Profitability (SEP) test, and it avoids the calculation of a term that under the null of no predictability should be zero but in practice may be sizable. In addition, our test does not require the strong assumption of independence used to derive the EP test. We claim that dependence is the rule and not the exception. We show via Monte Carlo simulations that the SEP test outperforms the EP test in terms of size and power. Finally, we illustrate the use of our test in an empirical application within the context of the commodity-currencies literature.

Background: In pregnancy and nursing, zinc plays an important role, including fetal development and milk secretion. Zinc in the lactation process is a crucial modulator of the mammary gland, which is very important for successful lactation.  Objectives: The purpose of this study was to analyze the total of Lactobacillus Bifidus using Quantitative RT-PCR in the feces of breastfed infants from mothers who were given zinc tablets. Methods: This type of research was experimental using a quasi-experimental post-test only with a control design and a quantitative approach. This research was carried out at Antang Perumnas Public Health Center, Kassi-Kassi Health Center, Jumpanang Baru Health Center and Bara-Barayya Health center from March 22 to June 22, 2021. The Population in this study were all newborns from mother with normal zinc levels in 2021 in the Makassar City Health Center area as many as 62 people. The sampling technique used purposive sampling, about 12 samples per group. To avoid dropout and increase power, the sample was then added with an estimated drop out of about 30%, 12 + (30% x 12) = 15.6, rounded up to 16. Each group consisted of 16 samples for breastfed infants from mothers who obtained zinc tablets (intervention) and 16 samples for breastfed infants from mothers who did not obtain zinc tablets (control). This study uses an Independent Sample Test. Results: This study showed that the group of breastfed infants from mothers obtaining zinc tablets had a higher mean value of 2947625215.62 compared to the control group of 162374516.97. There was a difference in the number of Lactobacillus in the intervention group after being treated with a statistically significant difference in the mean of –2785250698.65 by the Independent sample test analysis, the value of p = 0.009 (α < 0.05), which means there was a significant difference between the intervention groups and control group. Conclusion: The highest number of Lactobacillus was the intervention group which indicated a difference of Lactobacillus in the feces of breastfed infants from mothers who obtained zinc tablets.

Objectives. The study is aimed at describing attachment and coping strategies in the prison population, and relations between these two variables were tested. Sample and setting. The sample consisted of 122 men serving middle-security sentences mainly for property crime. The attachment was determined by the Czech version of the Experiences in Close Relationships Scale, and coping strategies were measured by The Stress Coping Style Questionnaire SVF 78. Hypotheses. The prisoners’ attachment and coping strategies were expected to be different from those of the normal population. The attachment anxiety and avoidance were expected to be related to coping strategies. Statistical analyses. One sample t-test and Wilcoxon one sample test were used for analyzing the differences in scores between the prison and normal population while the Pearson correlation and linear regression were used to test relations between variables. Results. Inmates were significantly different from the normal population both in their attachment and coping strategies. They exhibited higher attachment anxiety and avoidance compared to the normative sample, fearful avoidant attachment prevailed. Prisoners demonstrated higher Play Down, Distraction from Situation, Substitutional Satisfaction, Flight Tendency, Self-accusation, and Active Avoidance, they exhibited lower Guilt Denial and Rumination. Relational avoidance correlated negatively with positive coping strategies, relational anxiety correlated positively with negative coping strategies. Limitations. The main limitation of this study is the use of a non-representative sample and the self-assessment form of the methods employed.
