BackgroundSeveral studies have reported hip geometry to predict the femoral neck fractures. However, they showed inconsistency.ObjectivesTo determine the association between hip geometry and femoral neck fractures.MethodsPublished literature from PubMed and Embase databases (until May 25th, 2017) was searched for eligible publications. The information related to (1) name of first author; (2) year of publication; (3) country of origin; (4) sample size of cases and controls and (5) mean and standard deviation of cases and controls were extracted. The pooled odds ratios (ORs) and 95% confidence intervals (95% CIs) for the association between hip geometry and femoral neck fractures were assessed using random or fixed effect model. A Comprehensive Meta-analysis software, version 2.0, was used to analyse the data.ResultsA total of 11 studies were included in this study. Our results showed that increase in hip axis length (OR 95% CI = 1.53 [1.06–2.21], p = 0.025), femoral neck angle (OR 95% CI = 1.47 [1.01–2.15], p = 0.044) and neck width (OR 95% CI = 2.68 [1.84–3.91], p < 0.001) was associated with the risk of femoral neck fractures, whereas we could not find the correlation between femoral neck axis length and the risk of femoral neck fractures.ConclusionThere is strong evidence that elevated hip axis length, femoral neck angle and neck width are the risk factor for femoral neck fractures.The Translational Potential of this Article: Determining the hip axis length, femoral neck angle and neck width that are most highly associated with femoral neck fracture may allow clinicians to more accurately predict which individuals are likely to experience femoral neck fractures in the future.

Online learning has a negative impact on students, especially students who cannot use online learning support facilities. This has an impact on the decline in the quality of student learning outcomes. This study aims to analyze the effect of implementing digital literacy on students' science learning outcomes in online learning during the Covid-19 pandemic. This research is research in the field of education using a quantitative approach and correlation method. The population in this study amounted to 348 people. Determination of the sample in this study using the random sampling technique. The data collection methods used are questionnaires and science learning outcomes tests. The instrument used has gone through the stages of testing the validity and reliability of the instrument. The data analysis used in this research is simple linear regression analysis, which previously carried out several analysis prerequisite tests in the form of normality and homogeneity tests. The results showed that the calculation of the correlation coefficient of 4.412 is greater than 2.034 with a significance value of 0.000 less than an alpha value of 0.05, a coefficient of determination of 0.371 x 100% of 37.1%. Based on these results, it can be concluded that there is a positive and significant effect on the application of digital literacy on students' science learning outcomes.

The aim of this study to know Realistic approach influences Mathematics Education (RME) to the problem-solving ability. Methods This study is the development research of Plomp and Grameijer. This study population is N = 249. Based on the analysis of data using ANOVA test α > Sig, then the mathematics problem solving ability of students to use teaching materials RME higher than conventional. As in this study resulted in three products namely student books, teacher books, and Learning Instructional Theory (LIT).

Awal tahun 2020, dunia mengalami peristiwa pandemi COVID19. Hal ini merupakan termasuk kejadian terbesar pada abad ini. Pembatasan sosial diterapkan, sehingga pemerintah menetapkan kebijakan work from home (WFH). Hal ini membuat sistem pendidikan di seluruh dunia mengalami perubahan secara signifikan. Sekolah dilaksanakan di rumah melalui pembelajaran online. Merdeka belajar adalah kebijakan yang diterapkan oleh Kementrian Pendidikan dan Kebudayaan Indonesia. Merdeka belajar mendorong siswa untuk mampu berpikir literasi, numerasi dan berkarakter. Ketika Pembelajaran dilaksanakan di rumah kebijakan merdeka belajar sudah mulai diterapkan. Hal ini juga mempengaruhi dalam kualitas pendidikan IPA. Namun Pelaksanaan merdeka belajar ketika pandemi masih terdapat kendala. Sehingga kebijakan merdeka belajar harus dievaluasi untuk disempurnakan. Tujuan artikel ini menganalisis Disrupsi kebijakan merdeka belajar ketika pandemi untuk menyempurnaan menghadapi new normal pasca COVID19. Metode peneliti yang digunakan adalah tinjauan pustaka atau literature research. Hasil penelitian ini menyimpulkan bahwa penerapan merdeka belajar merupakan kebijakan yang tepat dalam mempersipakn sumber daya manusia yang berkualitas dan berkarakter untuk zaman revolusi Industri 4.0. Namun Indonesia masih mengalami permasalahan kendala dalam akses pembangunan yang belum merata seperti internet. Maka aritikel ini memberikan rekomendasi kepada pemegang kebijakann untuk penyebaran akses pembangunan dan melaksanakaan penelitian terhadap teknis pembelajaran merdeka belajar yang tepat untuk masing-masing daerah
