The Most Utilized Rotation and Translation Movement While in Ball-Possession among Futsal Players
No full textAbstractThe objective of this study was to identify the most utilized rotation and traction related movements among international futsal players when they are in a ball possession situation. A total of 4 matches from The AFF Futsal Championship 2014 were analyzed. The analyzed matches consist of two semifinal matches, 3rd-4th placing match and the final match. There are four indicators for rotation movement (half-trunk rotation, half-body rotation, quick-half trunk rotation, and quick-body rotation) and four indicators for traction movement (front traction, back traction, side traction, and sudden stop) that are selected to be observed in this study. Each indicator was divided into two categories, which are attacking and defensive mode. All matches were recorded using a full high definition video camera and analyzed using SportCode Elite (v. 10) and Dartfish EasyTag (v. 1.0.8) software. Two trained and experienced analysts were assigned to analyze all 4 matches. Inter- and Intra- analyst reliability studies were also performed in order to examine the content validity of the data obtained. Overall results indicated that the front traction during the defensive mode is the most utilized movement, among others, while back traction during the attacking mode is the least utilized movement. Front traction during attacking mode was found to be the highest number of usage during attacking mode while sudden stop traction during defensive mode is the least utilized movement among other defensive movements. Regardless of attacking or defensive mode, results show that front traction is the most utilized movement, followed by half-trunk rotation and side traction. This study also show that the rotation (47%) and traction movements (53%) utilized during competitive games are quite balanced. A similar result was also obtained when comparing between attacking (46%) and defensive mode distribution (54%) from overall data. Further study on futsal games should focus on the most utilized movement during competitive matches to understand more about the nature of the games

Mosque Institutions in Malaysia: what is the concept of the lyrics?
No full textThis article comprises discussions related to the concept of the Mosque in Malaysia, as far as conforming to the idea of rahmatan lilalamin, which is the primary basis of the Prophet Muhammad SAW. Contrary to the concept of rahmatan lilalamin then came Rahmah Mosque, which is concerned with the unification and peace of the universal ummah. This also repels a narrow understanding of the function of the mosque. In this paper, the author discusses the challenge of establishing a mosque institution that conforms to the concept of rahmatan lilalamin to expose readers to fend off all the extreme views of mosque functions. At the end of the writing, it is reiterated that the role of the mosque should be in line with the concept of lilalalmin's grace. This is based on the management, supervision, infrastructure facilities and mosque environment that can create the love of one's fellow Muslims and have a different society.Artikel ini terdiri dari diskusi yang berkaitan dengan konsep Masjid di Malaysia, sejauh sesuai dengan gagasan rahlatan lilalamin, yang merupakan dasar utama Nabi Muhammad SAW. Bertentangan dengan konsep rahmatan lilalamin kemudian muncul Masjid Rahmah, yang berkaitan dengan penyatuan dan kedamaian ummah universal. Ini juga mengusir pemahaman sempit tentang fungsi masjid. Dalam makalah ini, penulis membahas tantangan mendirikan lembaga masjid yang sesuai dengan konsep rahmatan lilalamin untuk mengekspos pembaca untuk menangkis semua pandangan ekstrem fungsi masjid. Di akhir tulisan, ditegaskan kembali bahwa peran masjid harus sejalan dengan konsep rahmat lilalalmin. Ini didasarkan pada manajemen, pengawasan, fasilitas infrastruktur dan lingkungan masjid yang dapat menciptakan kecintaan sesama Muslim dan memiliki masyarakat yang berbeda
Supervised feature selection using principal component analysis
No full textThe principal component analysis (PCA) is widely used in computational science branches such as computer science, pattern recognition, and machine learning, as it can effectively reduce the dimensionality of high-dimensional data. In particular, it is a popular transformation method used for feature extraction. In this study, we explore PCA’s ability for feature selection in regression applications. We introduce a new approach using PCA, called Targeted PCA to analyze a multivariate dataset that includes the dependent variable—it identifies the principal component with a high representation of the dependent variable and then examines the selected principal component to capture and rank the contribution of the non-dependent variables. The study also compares the feature selected with that resulting from a Least Absolute Shrinkage and Selection Operator (LASSO) regression. Finally, the selected features were tested in two regression models: multiple linear regression (MLR) and artificial neural network (ANN). The results are presented for three socioeconomic, environmental, and computer image processing datasets. Our study found that 2 of 3 random datasets have more than 50% similarity in the selected features by the PCA and LASSO regression methods. In the regression predictions, our PCA-selected features resulted in little difference compared to the LASSO regression-selected features in terms of the MLR prediction accuracy. However, the ANN regression demonstrated a faster convergence and a higher reduction of error. © The Author(s), under exclusive licence to Springer-Verlag London Ltd., part of Springer Nature 2023

Assessing the performance of regular surgical nose masks as a sampling method for SARSCoV- 2 detection in a cross-sectional study
No full textNose masks are widely worn for protection against respiratory pathogens, including SARS-CoV-2. They have been reported as possible substrates for viral sampling and testing for COVID-19 but, evaluations have so far been purposive; involving individuals known to have the infection and using improved materials on the nose masks to trap the virus. We investigated the feasibility of using the regular 3-ply surgical masks and, voluntary coughing as a mode of particle expulsion for detecting SARS-CoV-2 infections in a cross-sectional study at Ghana’s first COVID-19 testing reference laboratory, the Noguchi Memorial Institute for Medical Research, University of Ghana. Paired samples of naso-oropharyngeal swabs and nose masks already worn by 103 consenting adult participants (retro masks) were collected. Participants were also required to produce three strong coughs into a newly supplied sterile surgical nose mask. Pre-wetted swabs in Viral Transport Media (VTM) were used in swabbing the inner lining of each nose mask. The swabs used were then stored in VTM to maintain the integrity of the samples. PCR results of SARS-CoV-2 detection from the nose masks were compared to those from naso-oropharyngeal swabs (‘gold-standard’). Out of the 103 participants tested with all three methods, 66 individuals sampled with naso-oropharyngeal swabs were detected as positive, and the retro and new masks matched 9 and 4, respectively. Only 3 individuals were positive across all three sampling methods accessed. The retro nose masks performed better in matching the gold-standard results than the new mask + coughing method, with 90% vs 80% sensitivity, positive predictive value of 13.6% vs 6%, and a weak but significant linear relationship (adj. R2 = 0.1; P = 0.0004). Importantly, we also show that the nose masks would work for sampling whether individuals are symptomatic or asymptomatic since gold-standard PCR cycling threshold (Ct) values for positive individuals did not differ between the two groups (P 3, to improve the performance of sterile nose masks for SARS-CoV-2 detection.The authors are thankful to the Noguchi

The bar plots of positives and negatives (A) included all results reported following RT-PCR. ie. numeric Ct value and ‘undetermined’ (classified as negative). The proportion of positives detected from the reasons for getting the test (B) and Fisher’s exact test was used to test if infection was dependent on whether one shows symptoms or not (P>0.05). Each dot in ‘C’ represents individual Ct values. Only numeric values from RT-PCR were used (excluded ‘undetermined’). Test of significance was determined with Kruskal-Wallis.</p
