MicroLearning is not so new theoretical way of creating courses and study materials (processing subject matter) but maybe due to its limitations was not used much in university e-Learning course creation. Some authors see MicroLearning as one of trends in e-Learning, we look at reasons why MicroLearning can be suitable solution and which basic rules are with it connected. Presented is experience we gained when creating MicroLearning course for our students and pitfalls connected with this approach. Literature says that ML is not suitable for use with complex skills and creation of small learning units can lead to loosing general overview in specific subject matter. Described are students’ opinions on MicroLearning course we have created. Opinions were generally positive although just small sample of respondents was questioned.","PeriodicalId":20565,"journal":{"name":"PROCEEDINGS OF THE INTERNATIONAL CONFERENCE OF COMPUTATIONAL METHODS IN SCIENCES AND ENGINEERING 2019 (ICCMSE-2019)","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90633260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although constructed wetlands consist of simple systems, the water flow is complex and irregular, therefore, the study of hydrodynamics requires the use of experimental technics such as tracer experiments. To evaluate the effects of the use of three different analytical methods to compute the concentration of lithium chloride on the main hydrodynamics parameters, tracer experiments were conducted in ten independent lab-scale constructed wetlands. The concentration of lithium chloride in the output flow of the wetlands was calculated by flame photometry, electrical conductivity using a calibration curve and electrical conductivity using the salt molar conductivity. The paired samples T-test or the non-parametric Wilcoxon’s Signed-Ranks test were used to demonstrate that the computed hydraulic retention time and the number of tanks accordingly with the tanks-in-series model were not significantly affected by the selected analytical method.","PeriodicalId":20565,"journal":{"name":"PROCEEDINGS OF THE INTERNATIONAL CONFERENCE OF COMPUTATIONAL METHODS IN SCIENCES AND ENGINEERING 2019 (ICCMSE-2019)","volume":"66 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77821476","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we developed FUJI force-field parameters for sulfo-tyrosine and phospho-tyrosine residues to investigate the effect of tyrosine modification. Then, we applied the new parameters to molecular dynamics simulations of CCR5-derived peptide (pep1) systems. We found that the effect of phosphorylation on the structure was much greater than that of sulfation. In addition, we characterized the effects of sulfation and phosphorylation on the interaction between pep1 and its antibody 4B08 by using the FUJI force-field parameters developed here.","PeriodicalId":20565,"journal":{"name":"PROCEEDINGS OF THE INTERNATIONAL CONFERENCE OF COMPUTATIONAL METHODS IN SCIENCES AND ENGINEERING 2019 (ICCMSE-2019)","volume":"342 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82965181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two main groups of people were recruited for the study: (1) active people (n=607; regularly participating in sport activities) and (2) inactive people (n= 494; not participating in sports activities). We used second part of S.QUA.L.A. questionnaire where participants evaluated perceived satisfaction with 23 indicators using the 5-point rating scale. The lower mean score meant the higher perceived satisfaction. For our investigation we analysed perceived satisfaction with only one indicator “overall health”. Statistical analysis was performed using IBM SPSS version 23.0. The data were statistically tested by the Kolmogorov-Smirnov test of the sample distribution normality. One-way ANOVA was used to determine the differences in perceived satisfaction with health within three evaluated groups based on their health status. Post-hoc Bonferroni test was used to examine the differences in satisfaction with health between two groups of population based on their health status. Student’s two-sample t test was used to examine the differences between active and inactive people within each population group based on their health status. We found the highest level of perceived satisfaction with overall health in the group of healthy actively living population and the lowest perceived satisfaction with overall health in the group of inactive people with NCDs. In the group of active as well as inactive people we found significantly higher perceived satisfaction with health in the group of healthy people comparing people with NCDs and people with disabilities. No significant differences were found in the comparison of perceived satisfaction with overall health between people with NCDs and people with disabilities nor in the group of active neither inactive population. In all groups of people related to their health status the significantly higher perceived satisfaction with health was demonstrated by actively living populations comparing inactive population.The aim of our investigation was to find out the differences in perceived satisfaction with health within three evaluated groups with different level of health status: healthy people, people with noncommunicable diseases (NCDs) and people with disabilities.

The study has revealed dendrochronology to be an efficient method for determining triggering factors of landslide activity as the method provides long data sets on past landslide activity which are suitable for statistical analyses and comparisons with precipitation record. In case of the Garbatka landslide the oldest dated landslide activity event is 1942. Dendrochronological record has been compared with precipitation record from the nearest gauging station which is available since 1951. Correlation of data on landslide activity and precipitation data has shown that the landslide under study is sensitive to high short-term precipitation totals (up to 5-days) and to extremely long-term precipitation totals (60-days and 90-days). The main factor driving the activity of the landslide under study is total annual precipitation which is characterized by the highest level of correlation coefficient.
