ABSTRACT The objective of this study was to assess the effectiveness of three surface friction techniques for the removal of organic material. A quantitative, descriptive and exploratory study was developed to evaluate the presence or not of organic material before and after the cleaning and disinfection process of surfaces of bedside tables of patients hospitalized at an Intensive Care Unit. Three friction techniques were executed in the one-way, two-way and centrifugal sense, individually, three times on each table, during alternate weeks. For each patient unit and friction technique, a single table and three sides of cloth were used, moistened with 70% (w/v) alcohol. The organic matter was detected through the presence of adenosine triphosphate by bioluminescence, using 3M(tm) Clean-Trace(tm) ATP Systems. For each technique, 13 samples were collected before and 13 after the cleaning/disinfection process, totaling 78 samples of adenosine triphosphate by bioluminescence. No statistically significant difference was found among the removal techniques of organic matter. This study demonstrated that none of the three surface friction methods was better than the other to remove organic matter. Nevertheless, further research is needed in which other cleaning/disinfection indicators and surfaces are considered.

<p>The advent of technology has improved the way statistics is taught and learned. It is claimed that the use of computer-based instructional tools can actively explore the meaning of statistical concepts among the students, as well as enhance their learning experiences. This study aimed to compare three methods of statistical analysis namely, the traditional technique (use of the calculator), Microsoft Excel and Statistical Package for Social Sciences (SPSS) software. This investigation utilized the experimental design, specifically the One-Group Pretest – Posttest Design. There were six education students who self-assessed their attitude before and after the introduction of the use of various computation techniques and performed the statistical analysis considering also the completion time required for each process. Results of the study revealed an increase in the level of attitude among the respondents form the pretest to the posttest. Also, the cognitive level regardless of the approach was very high. However, the t-test failed to establish a significant difference in the attitude among the respondents. On the other hand, there were significant differences in both the test scores and completion time of the respondents in the three methods in favor of SPSS.</p><p> </p><p><strong>Keywords: </strong>Information technology, statistics, traditional technique, Microsoft excel, SPSS, comparative analysis, experimental research design, Davao City, Philippines. </p>

Background: Failures in the processes of cleaning and disinfecting health service surfaces may result in the spread and transfer of pathogens that are often associated with healthcare-related infections and outbreaks. Aims: To assess the effectiveness of environmental surface cleaning and disinfection in a hospital clinic. Method: The study was conducted in a nursing ward with 45 beds. A total of 80 samples from five high-touch surfaces were evaluated before and after cleaning and disinfection, using the following methods: visual inspection, adenosine triphosphate bioluminescence assay, aerobic colony count, Staphylococcus aureus colony count, and evaluation of resistance to methicillin. The data analysis used nonparametric comparative and correlative tests to observe any differences in the pre- and post- cleaning and disinfection results for the surfaces assessed. Results: Effective cleaning and disinfection had a significant effect on only two surfaces when measured for the presence of adenosine triphosphate, the inner bathroom door handle (p=0.007) and the toilet bowl (p=0.01). When evaluated for Staphylococcus aureus colony count, the toilet flush handle also demonstrated a significant effect (p=0.04). Conclusion: The effectiveness of cleaning and disinfection of the surfaces tested was not satisfactory. An educational intervention is recommended for the cleaning and disinfection staff and the nursing team at the healthcare facility. Relevance to Clinical Practice: The data in the study revealed that daily hospital cleaning and disinfection in the sampled sites are not sufficient in medical and surgical wards. Hospital cleanliness must be reevaluated from the point of view of materials, such as an adequate supply of clean cloths, in addition to establishing more precise cleanliness protocols and accurate monitoring systems.

One of the tasks of the development of children aged 11-15 years is to think in a more abstract and logical way and more idealistic thinking. This ability to think will be disrupted if teenagers have difficulty concentrating during learning. Therefore we need a method that is fun and can make children relax in learning so that they can concentrate their concentration on ongoing learning. One method that can be used is the Murrotal Al-Qur'an therapy. The aim of the study was to determine whether there was any effect of murottal therapy on the concentration of students at Muara Enim 2 MTsN. This study used a quasi-experimental design with the design of the one group pretest posttest. The sample used was all students of class VIII.G at MTsN 2 Muara Enim. The results showed that the average concentration score of class VIII.G students before Murottal therapy was given was 10.84 with a standard deviation of 3.043. While the average concentration score of class VIII.G students after being given murottal therapy was 17.90 with a standard deviation of 1.233, so that the difference in mean concentration scores before and after murottal therapy was 7.06 with a standard deviation of 1.81. Wilcoxon signed ranks test obtained ρ value = 0,000, with a value of α = 0.05 (p <0.05), this shows that there is a significant difference between the concentration of students before and after being given murottal therapy. It is expected that the school can make a policy about the application of murottal therapy in increasing student concentration.

This study aimed to investigate the effect of using news as authentic materials for essay writing skills. This experimental study employed the one-group pre-test and post-test design to 18  fourth-semester students who joined the Essay Writing Course in one of the universities in Indonesia. These students were selected through systematic random sampling and went through treatments for 12 meetings where they were taught in a hybrid learning setting. The first four meetings used the conventional face-to-face classroom interaction. The rest of the meetings were done online because of the outbreak of COVID 19. The instruments to collect data were tests and documentation. Before they were given to the students, the teaching materials, pre-test, and post-test designs were tested and validated. The authentic materials were news texts about global issues such as poverty, environmental protection, gender, race and ethnicities, and diseases. Two raters scored the students’ writing by using Jacobs ESL Composition Profile. The researchers used IBM SPSS 25 software to analyze the data. The results of a paired sample t-test analysis showed that there was no significant difference in the students’ writing scores before and after using news as authentic materials (p = .959 α = 0.05). The paper further discusses the implications of this study for theoretical and practical use.

Objective To study the one-year effect of wearing orthokeratology (OK) lenses on the visual quality of juvenile myopia. Methods The right eyes of 36 juvenile myopias were retrospectively studied in this work. Q-value, e-value, corneal curvature, strehl ratio (SR), modulation transfer function (MTF) and wavefront aberration (WA) were compared before and at 1, 3 and 12 months after wearing OK lenses. The SR, MTF and WA of cornea, internal optic and ocular were analyzed separately. The spherical and cylinder diopter, vision acuity, compensating factor (CF) and compensative rate (CF%) were compared before and at 12 months after wearing OK lenses. Results (1) The vision of LogMAR increased and the corneal curvature decreased significantly after wearing OK lenses. There was no significant difference for the e-value before and after wearing OK lenses. The Q-value increased at 1 month but decreased at 3 and 12 months remarkably. (2) The ocular and internal optic SR and MTF increased significantly at 1 month and then remained stable. The MTF in different spacial frequencies increased after wearing OK lenses. There was no significant difference for the corneal SR before and after wearing OK lenses, and the corneal MTF decreased significantly after wearing OK lenses. (3) For the ocular, the total higher order aberration (HOA), spherical, coma and trefoil aberrations increased, and the total aberration, total lower order aberration (LOA) and defocus aberration decreased obviously except astigmatism. The corneal aberrations increased significantly after wearing OK lenses except astigmatism. For the internal optic, the total aberration, total LOA and defocus aberration decreased, and the total HOA, coma and trefoil aberration increased significantly except the astigmatism and spherical aberrations. (4) The CF and CF% of total aberration, total LOA, total HOA and coma aberrations increased, and those of astigmatism and spherical decreased at 12 months. Conclusions Orthokeratology is effective in correcting the refractive error and improving the vision quality of juvenile myopia over the one-year follow-up period.
