AbstractGranules come from small particles which then become single larger particles to form a lump. The binder in the granules is used to ensure the incorporation of the powder particles in the granules. Manihot starch is a natural binder and polyvinylpyrrolidone is a synthetic binder, because manihot starch has poor flow properties, it is necessary to modify it by pregelatination. The purpose of this study was to determinethe characterization of the physycal properties of granules with a natural binder of pregelatinized starch manihot and and synthetic polyvinylpyrrolidone on the physical properties of the granules. Variations in the concentration of pregelatinated starch manihot were 3% and 5% respectively. The granulation process is carried out by mixing all materials that have easy flowing properties. The resulting granules were evaluated for their physical properties and then the data were analyzed using SPSS with the One Way ANOVA method with a 95% confidence level. The results of the organoleptic test are white granules but on F1 and F2 there are brown spots then round shape and characteristic odor, the flow time meets the requirements of 10 g/second, the angle of repose test meets the requirements <30˚, compressibility meets the requirements <15%. The results of statistical analysis showed a significant difference (sig <0,05) in the flow time test. The optimum concentration of pregelatiansi manihot starch is 5% (F2) and polyvinylpyrrolidone 5% (F4). The Suggest for further researchers can use other natural excipients and make modifications to improve the physical characteristics of the granules.

The aim of this study was to determine aerobic fitness through the VO2max treadmill test of elite Bulgarian taekwondo players with international results, and to determine whether the aerobic system had an effect upon the sports result in taekwondo. Fourteen elite taekwondo athletes, members of the Bulgarian national team (8 male and 6 female) were tested using a continuous progressive treadmill test. Physiological characteristics such as maximal oxygen uptake(VO2max), blood lactate and heart rate were measured. The male athletes recorded 58.2±3.4 ml kg–1 min–1 and the female 46.0±2.8 ml kg–1 min–1. The lactate level reached its highest at the 6’ after the VO2max with results for the males of 11.5±3.7 (mmol l-1) and 9.9±4.1 (mmol l-1) for the females respectively. A comparison between our results, regarding VO2max and previously reported was made using the One-way Anova for independent samples. It showed no significant difference between the male subjects (58.2±3.4 versus 60.7±3.3 ml kg(-1) min(-1), p>.05) and significant difference between the female ones (46.0±2.8 versus 49.8±2.8 ml kg(-1) min(-1), p<.05). Investigated also was the number of kicks executed by the winner of -49 kg weight category and her direct opponents during the 2019 Grand Prix Sofia. It was discovered that the winner kicked an average of 86.25 times per match and her kicks during the Grand Prix Sofia accumulated to 390 in total. It is our conclusion that the aerobic fitness does not play a significant role in taekwondo.

Purpose This study aims to investigate attitudes toward cheating among business students at a private university in Kenya and examine if a significant difference exists in cheating perceptions among students who have completed one or two ethics courses, and those who have done none. Design/methodology/approach A total of 554 undergraduate business students participated in this research. Data were analyzed using descriptive statistics and the one-way ANOVA. Findings The results found that students perceived cheating in exam-related situations as quite serious, while cheating on written assignments was not considered a serious offence. Results of the one-way ANOVA indicate that there was a significant difference in the cheating perceptions ratings for the three groups. Post hoc comparisons using the Tukey HSD test indicate that the mean score for students who have done two ethics courses was significantly different from that of students who have done only one ethics course. Practical implications This study has a number of implications for educators and administrators. Ethics instruction cannot achieve its desired effect on student behavior without institutional support. Administrators also need to be cognizant of the influence that school environment has on student cheating. Faculty and university administrators can influence students’ behavior in the way they practice academic integrity in their teaching and administrative functions. Originality/value To the best of the author’s knowledge, this research is the first study to explore academic cheating at a private Kenyan university where ethics instruction is taught to undergraduate students.

Scientific Literacy (SL) is an important competency to deal with and keep up with the increasingly sophisticated technological developments. However, information about the SL of prospective gifted young scientists over 15 years old has not been widely revealed holistically. Therefore, this survey research aimed to investigate the SL performance of prospective gifted young scientists holistically and compare the SL performance based on the grade level. A total of 278 students from a public senior high school in Jombang Regency, East Java Province, Indonesia, participated in this research. They were asked to take the SL test with 18 essential question items. As a result, the participants still showed low SL performance (total success rate = 40). The one-way ANOVA test results indicated no significant difference in the participants' SL performance based on the grade level. Therefore, three recommendations were provided: teachers should use various learning models, SL should be an explicit focus in science and non-science classrooms, and schools need to be equipped with supporting facilities to accommodate student readiness to practice SL.

A new coronavirus denominated first 2019-nCoV and later SARS-CoV-2 was found in Wuhan, China in December of 2019. This paper compares three mathematical methods: nonlinear regression, SIR, and SEIR epidemic models, to track the covid-19 disease in nine countries affected by the SARS-CoV-2 virus, to help epidemiologists to know the disease trajectory, considering initial data in the pandemic, mainly 100 days from the beginning. To evaluate the results obtained with the three methods one-way ANOVA is applied. The average of predicted infected cases with SARS-CoV-2, obtained with the mentioned methods was: for United States of America 1,098,508, followed by Spain with 226,721, Italy with 202,953, France with 183,897 United Kingdom with 182,190, Germany with 159,407, Canada with 58,696, Mexico with 50,366 and Argentina with 4,860 in average. The one-way ANOVA does not show a significant difference among the results of the projected infected cases by SARS-CoV-2, using nonlinear regression, SIR, and SEIR epidemic methods. The above could mean that initially any method can be used to model the pandemic course.
