Besides functioning as a place of learning, schools can also be a threat of disease transmission . measurement number of bacteria in the air-conditioned classrooms Wulan R22 (2016) 12.167 CFU / m3 , Nur Latifah (2018) an average of 217.92 colony / hr / ft2 , hadita (2018) 331.6 colonies / hr / ft2 . Research question is how is the effectiveness of UVAerator in reducing the number of air germs and dust levels in the lecture hall R22 building Campus 7 Poltekkes Kemenkes Semarang ? Research objectives is to find the effectiveness of UVAerator in reducing the number of air germs and dust levels in the lecture hall. Research method included a quasi-experimental design with a non-equivalent control group pre test - post test. Data collection by measuring, observational, interview. The variables were temperature, humidity, lighting, air germ count, dust content. Analysis using pairet-t test comparisons and unpaired t test data. Result, the average number of bacteria with no air space UVAerator in the morning is ( 668,00 g / m3 ) and in the afternoon is ( 680.10 g / m3 ) the difference was not significant (p = 0.873), whereas the existing space UVAerator in the morning ( 876.50 g / m3 ) and in the afternoon ( 655.50 g / m3 ) shows significant difference (p = 0.001). The number of room air germs that do not exist and have UVAerator is significantly different (p = 0.002), the number of room air germs that are not there and without any UVAerator is not significant (p = 0.763), while the change in the number of room air germs that does not exist and exist UVAerator has a significant difference (p = 0.015). On average PM10 space dust that has no UVAerator in the morning ( 12.38 ug / m3 ) and in the afternoon ( 17.38 ug / m3 ) shows significant difference (p = 0.008), whereas the existing space UVAerator in the morning ( 11.63 g / m3 ) and day ( 14.50 µg / m3 ) shows that the difference is not significant (p = 0.127). PM10 dust in the room that does not exist and there is no UVAerator ported, the difference is not significant (p = 0.821), the PM10 dust in the room noon and there is UVAerator, the difference shows that it is not significant (p = 0.432), while the change in room PM10 without dust and there is a difference in UVAerator significant (p = 0.004). In conclusion, the effectiveness of reducing the number of air germs without UVAerator on average (4.56%), with UVAerator (-24.52%), the difference was not significant (p = 0.057). The effectiveness of reducing PM10 without UVAerator, mean (60.50%), with UVAerator (38.30%), the difference was not significant (p = 0.369).

The present study investigates the effect of negative emotions (focusing on disappointment, sadness and regret) on cognitive schemas. The sample consist in students from the University of Bucharest (convenience groups). A univariate unifactorial experimental design was used, as the current study had one independent variable, negative emotions, and a dependent variable, cognitive schemas, which was measured with the Core Beliefs Questionnaire instrument. We applied T test for independent samples, using SPSS. The t test was statistically significant, t (45) = 2.57, p <0.05. The confidence interval (95%) for the difference between the averages is between 2.95 and 24.35. After applying the intervention, the evaluated sample (M = 43.17, SD = 29,074) showed a statistically significant difference compared to the control group (M = 29.52, SD = 11.257). The data collected support the main research hypothesis of the study, negative emotions can bring about changes in certain cognitive schemas by modifying, altering or disrupting them.

The purpose of the present study is to investigate the effect of explicit affective strategy instruction on the speaking performance of Freshmen English majors at Faculty of Education, Suez University, Egypt. The design of the study is a pre-post quasi experimental one. The instrument is a pre/post speaking performance test (designed by the researcher). Participants were eighty Freshmen English majors, randomly divided into two groups: a control group (N=40) and an experimental one (N=40). During the experiment, the experimental group was explicitly taught some affective strategies (lowering anxiety, encouraging yourself and monitoring emotions) while the control group was taught using the traditional method. All participants were tested using the pre/post speaking performance test before and after the intervention. The difference between the post test&rsquo;s mean scores of the control and experimental groups were calculated using Independent Samples t-test and the difference in the mean scores between the pre- and post tests of speaking performance was calculated for each group separately using Paired Samples t-test. A significant difference was found between the post test&rsquo;s mean scores of the control and the experimental groups in favor of the experimental group. Moreover, a significant difference was found between the mean scores of the pre and post test of the experimental group in favor of the post test. It was concluded that participants&rsquo; level of speaking performance significantly improved after receiving the explicit affective strategy instruction.

Objectives : to observe the effect of badminton in myopia progression among children in Yogyakarta. Methods : This is a cohort study involving 139 eyes from 77 children. The subjects were divided into 2 groups: badminton (n=73) and control (n=66) group. The refractive error was measured by using auto- refractometer with additional cycloplegic agent (1% cyclopentolate). Myopia progression between baseline and 6 month follow up in each group were compared by using Paired T-Test Analysis. The difference of myopia progression in both group were compared by using Independent Sample T-Test Analysis. The relative risk of myopia progression by playing badminton was analysed by using 2x2 table analysis. Results : The mean refractive error in the badminton group was -1.03 ± 0.62 D (baseline) and -1.07 ± 0.64 D (6 months), while in the control group was -1.11 ± 0.66 D (baseline) and -1.24 ± 0.69 D (6 months). There was significant difference in the mean refractive error between baseline and 6 months in each group (p<0.05). Myopia progression in badminton group was 0.04 ± 0.10D, while in control group 0.12 ± 0.22. There was significant difference in myopia progression between two groups (p<0.05). Badminton is also significant protective factor against myopia progression in children (RR: 0.329 (0.157-0.687); p<0.05), even though another factor such as near-work, outdoors activities, and hereditary factor could confound the progression. Conclusion : Children who are routinely playing badminton show less myopia progression. There is statistically significance but not clinically significant difference in myopia progression between two groups. Playing badminton is a protective factor towards myopia progression
