Many universities provide blended, online or e-learning courses. Many LMS platforms are used for online learning and testing students in various fields. Several virtual meeting platforms are used for online learning and communication. The use of these platforms at universities skyrocketed during the Covid-19 pandemic. This paper focuses on teachers’ experience and satisfaction with different tools for online learning in comparison with traditional, face-to-face teaching methods. The authors surveyed three academies of applied studies in Serbia. According to the survey, most teachers used online learning platforms as well as virtual meetings during the Covid-19 pandemic and they were satisfied. The results of the survey imply that the majority of teachers find blended learning to be the optimal method of teaching in the future.","PeriodicalId":389229,"journal":{"name":"Sixth International Scientific Conference ITEMA Recent Advances in Information Technology, Tourism, Economics, Management and Agriculture","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117098702","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}

{"title":"Priority Substances in Waters of Albanian Ports","authors":"Esmeralda Halo, B. Murtaj, A. Nuro","doi":"10.31410/itema.2022.423","DOIUrl":"https://doi.org/10.31410/itema.2022.423","url":null,"abstract":"This study was to determine the concentration of organochlorine pesticides, polychlorinated biphenyls, polycyclic aromatic hydrocarbons, and BTEX (benzene, toluene, ethylbenzene and o-, m- p-xylenes) in water samples of Adriatic Sea on the Albanian coastline. These pollutants are clas­sified as priority substances because of their stability and toxicity. Stations near the ports of Durres and Vlora were selected for this study. Durres and Vlora ports are the largest ports in Albania which are processing more than 90% of shipping transport for people and commerce in Albania. Intense ship transport and commercial processing are the main reasons for water pollu­tion in port areas. Water currents and new arrivals from Albanian rivers can influence their pollution. Marine water samples from the ports of Durres and Vlora were taken in for the same stations in two periods, May and July 2022. Liquid-liquid extraction (LLE) and hexane as extracting solvents were used to isolate organochlorine pesticides and PCBs by water samples. PAHs were extracted using two steps LLE technique. Firstly, by using dichloromethane and after that hexane as extracting solvent. Organic phases were dried by using Na2SO4 anhidrous. Clean-up procedures were performed by using SPE techniques. After the concentration, the samples were injected in Var­ian 450 GC equipped with ECD and FID detectors. BTEX was analyzed us­ing HS/SPME technique followed by GC/FID technique. Organochlorine pes­ticides (mostly their metabolites) were detected almost in all analyzed wa­ter for both periods of sampling. The main factors can be their previous use, new arrivals from rivers, and the water currents of the Adriatic Sea. PCBs, PAHs and BTEX were found almost for all analyzed samples. Their presence could be because of anthropogenic factors (intense activity and ship trans­port) in the port area. The higher level of all pollutants was in July because of the intense ship transport in this period of the year. The higher levels were found inside port areas for both periods. Priority substance levels in water samples of Durres and Vlora ports were higher/comparable with reported levels of them from other stations of the Adriatic Sea (Albania coast).","PeriodicalId":389229,"journal":{"name":"Sixth International Scientific Conference ITEMA Recent Advances in Information Technology, Tourism, Economics, Management and Agriculture","volume":"10 14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134111230","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}

The methodology underlying the study was based on the use of the MI­TRE Adversarial Tactics, Techniques and Common Knowledge framework as a matrix of tactics and techniques based on real scenario observations. The main results emphasize the importance of incorporating the Security Oper­ations Center as a barrier against cybersecurity threats.

Basically, COVID-19 has accelerated the inevitable change that has already begun and that has received an incredible boost on the way to the introduc­tion of e-learning. In this paper, the authors explore the question of wheth­er e-learning at the University of Rijeka (UNIRI) Constituents’ is really at a level where it can be said to be e-learning in the true sense of the word and whether it can be classified as successful. Since e-learning is an upcoming educational trend, it deserves special attention and a concrete assessment of its current status so that policymakers can direct their actions toward im­provements.

The country’s entry into the international market is producing increased visits primarily driven by curiosity, a motivational factor that hardly ensures repeated visits. Phys­ical development is present, pressure on resources builds on and barely any coordinated actions are taken by regions in the name of long-term compet­itiveness and sustainability. Initiatives such as pilot testing European Tour­ism Indicator System for sustainable management at the destination level in the Vlora region in South Albania, a territory high in demand for tourism services, produced substantial information about the state of development and strategic documents. This paper aims to shed light on regional strate­gies for sustainable development and the level of tourism private sector en­gagement.

To obtain more robust results, we divide the sample into two sub-periods: the Quiet period, from September 18th, 2017, to December 31st, 2019; and the Stress Period, from January 1st, 2020, to September 15th, 2022, marked by the global pandemic (COVID-19), the oil price war in 2020, and the Russian invasion in 2022. The time series exhibit non-normal distributions due to the presence of fat tails, a characteristic that is common in periods of extreme volatility. The results of the VAR Granger Causality/Block Exogeneity Wald Tests model verified the existence of 16 pairs of markets showing co-movements between them dur­ing the quiet subperiod. The market that causes more co-movements is the Austrian stock market (ATX), while the Russian stock index (IMOEX) does not cause shocks in the markets under analysis. In the Stress subperiod, we ver­ify the presence of 42 pairs of markets causing (each other in the Grangeri­an sense. The stock indexes ATX, BUX, CROBEX, and PRAGUE PX show 6 caus­al relations in 7 possible, while the capital markets of Russia (IMOEX) and Po­land are the ones that cause less (4 in 7 possible). In conclusion, we verify that the events that occurred in 2020 and 2022 have significantly increased the movements in these regional markets. Such findings could put into question the implementation of efficient portfolio diversification strategies and even­tually some gains above the market average due to arbitrage levels. The au­thors consider this evidence to be relevant for supervisors, regulators, and in­vestors operating in these regional markets.","PeriodicalId":389229,"journal":{"name":"Sixth International Scientific Conference ITEMA Recent Advances in Information Technology, Tourism, Economics, Management and Agriculture","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131972844","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}
