In the present thesis, we analysed aspects of health and physical activity in preschool children before, during and after interventions to contain the spread of coronavirus (SARS-CoV-2). 195 parents from Ljubljana, Vrhnika, Brezovica, Horjul and their surroundings took part in the survey. Only parents of children aged 2–6 years were included in the survey. We were interested in the frequency of children's physical activity in the urban and natural environments, and whether certain epidemic periods had an impact on the frequency of physical activity and time spent outdoors. We compared the frequency of children's outdoor activity before and during the epidemic and compared it with other foreign studies. In addition, we wanted to know how often children consumed fruit and vegetables during each wave of the epidemic and whether they were more likely to reach for fruit or vegetables than before. We also wanted to know whether children had regular mealtimes, as they did when in kindergarten. All data were collected in July 2021 through an online survey sent to parents via various social networks. The data were then analysed in Microsoft Excel. The analysis was carried out in four phases. First, the data were quantified, recorded and tabulated according to the urban or natural environment, according to the frequency and time of physical activity during the week and at the weekend, and according to the frequency of fruit and vegetables consumption over a period of time and the number of meals per day. Then we calculated the percentages to see clearer differences in the variables. In the third step, the variables were plotted in graph from. In the final stage, we explained all our findings in writing and linked them to the literature and other international research. The study found that children's physical activity in both outdoor urban and outdoor natural environments was the lowest during the first wave of the epidemic, with a 23.5 % decrease in urban and a 4.5 % decrease in natural environment during this period. Children were more likely to eat fruit than vegetables, with 74 % of children eating fruit and 58 % eating vegetables daily during the epidemic. Most parents (47 %) provided the same number of meals for their children during lockdown as before COVID-19, when children were in kindergartens, namely 3 main meals and 2 snacks. However, most children (50 %), had these meals adapted to their daily situation. The results showed that people got accustomed to a new lifestyle during the different waves of the epidemic, but became aware of the importance of children's outdoor physical activity as the frequency of outdoor physical activity increased again after the first wave of the epidemic.

O presente trabalho investiga o comportamento dos investidores nos mercados financeiros em períodos de crise. Em particular, este estudo investiga quais os determinantes sociodemográficos do comportamento dos investidores durante o período de crise fruto da pandemia COVID-19, usando o principal índice português, o PSI 20, como objeto de estudo. Os dados foram disponibilizados por uma das principais instituições financeiras do mercado português e contêm transações de 15 943 indivíduos para os anos de 2019 e 2020. Através de testes ANOVA e do método dos mínimos quadrados, é concluído que há efetivamente variáveis sociodemográficas que impactam o comportamento dos investidores nos mercados financeiros em períodos de crise. Investidores do género masculino são os mais ativos no mercado bolsista em períodos de crise e o estado civil não se relaciona com a atividade nos mercados de capitais. Riqueza, educação e a idade do investidor têm um impacto positivo nos montantes investidos em períodos de crise e a antiguidade do cliente tem um impacto negativo. Relativamente às características do individuo perante a instituição, a posse de uma conta de depósito a prazo com a instituição tem um impacto negativo no montante investido no mercado de capitais em períodos de crise. Já a posse de pelo menos um empréstimo com a instituição demonstra ter um impacto positivo na variável, com os investidores que possuem empréstimos a investir mais no mercado de capitais durante a pandemia. This paper investigates the sociodemographic characteristics of capital markets investors' behaviour during the pandemic period. For this purpose, we use data provided by a major Portuguese financial institution that comprises data for 15,943 individuals' transactions during 2019 and 2020. Using ANOVA tests and OLS estimations it was concluded that there are sociodemographic variables that impact investors’ behaviour towards the market in crisis periods. Male investors are more active during crisis periods than female investors and marital status was seen to not impact trading activity. Investors' wealth, education and age influence invested amounts in a positive way whereas client seniority has a negative impact. The possession of a savings account was seen to impact trading activity negatively while the possession of a loan had a positive impact on amounts traded during the pandemic.

2019 yılının sonlarına doğru ortaya çıkan ve tüm dünyada pandemiye sebep olan yeni koronavirüs hastalığı (COVID-19), 2020 yılında tüm dünyada milyonlarca insanı enfekte etmiştir. Günümüzde COVID-19 ile ilgili çalışmalar giderek artmakta ve her geçen gün bilgiler değişmektedir. Bizim de bu çalışmadaki amacımız COVID-19 tanısı ile hastanede yatan hastaların yatış süresine etki eden faktörlerin incelenmesidir. Çalışmaya Mart 2020 ve Haziran 2020 tarihleri arasında hastanemiz enfeksiyon hastalıkları servisinde yatan 102 hasta dahil edildi. Hastaların yaşı ve cinsiyeti, komorbid hastalıkları, vital bulguları, yatış esnasındaki lökosit, nötrofil, lenfosit, monosit, hemoglobin (Hb), trombosit (PLT), ortalama trombosit hacmi (MPV), aspartat aminotransferaz (AST), alanin aminotransferaz (ALT) üre, kreatin, C-reaktif protein (CRP), fibrinojen, laktat dehidrojenaz (LDH), kreatinin, protrombin zamanı (PT), uluslararası normalleştirilmiş oran (INR), procalsitonin (pct), D-dimer, ferritin, troponin, nötrofil/lenfosit oranı (NLR) trombosit-lenfosit oranı (PLR), monosit-lenfosit oranı (MLR) ve MPV-lenfosit oranı (MPVLR) değerleri retrospektif olarak incelendi. COVID-19 PCR ve akciğer tomografilerindeki parankimal tutulumları sınıflandırıldı. Aldıkları antiviral, antibiyotik ve diğer destek tedavileri ve hastanede yatış süreleri kayıt edildi. İstatistiksel analiz için verilerin dağılımı Kolmogorov-Simirnov testi ile incelendi. İstatistiksel analizler SPSS v.22 paket programı ile yapıldı, anlamlılık düzeyi 0,05 olarak dikkate alındı. Çalışmamızda 51 erkek ve 51 kadın toplam 102 hasta değerlendirildi. Hastaların yaş ortalaması 56,51±15,48 yıl olarak bulundu. Ortalama hastane yatış süresi ortalama 7,58±3,35 gündü. DM, HT ve malignitesi olan hastalarda ve favipravir, enoksaparin ve vitamin C desteği alan hastalarda daha uzun hastane yatışı olduğu görüldü. Uzun süre hastane yatışı olan hastalarda ateş, procalsitonin, AST, LDH değerlerinin kısa yatış süresi olan hastalara göre anlamlı olarak daha yüksek olduğu saptandı. Lenfosit sayısı ve yüzdesi, NLR, monosit sayısı, MPV/lenfosit oranı değerleri ise yedi günden uzun süre yatan hastalarda anlamlı düşük bulundu. iii The new coronavirus disease (COVID-19), which emerged towards the end of 2019 and caused a pandemic all over the world, infected millions of people all over the world in 2020. Nowadays, studies on COVID-19 are increasing and information changes day by day. Our aim in this study is to determine the factors affecting the length of stay of patients hospitalized with the diagnosis of COVID-19. 102 patients hospitalized in our hospital's infection ward between March 2020 and June 2020 were included in the study. Age, gender, comorbid diseases, vital signs, leukocyte, neutrophil, lymphocyte, monocyte, hemoglobin, platelet, mean platelet volume (MPV), aspartate aminotransferase (AST), alanine aminotransferase (ALT) urea, creatine, c-reactive protein (CRP), procalcitonin, d-dimer, fibrinogen, lactate dehydrogenase (LDH), creatinine, prothrombin time (PT), international normalized ratio (INR), procalcitonin (pct), d-dimer, ferritin, troponin, neutrophil / lymphocyte ratio (NLR) platelet-lymphocyte ratio (PLR), monocyte-lymphocyte ratio (MLR) and MPV-lymphocyte ratio values were analyzed retrospectively. Parenchymal involvement in COVID-19 PCR, hospitalization tomography were classified. The antiviral, antibiotic and other supportive treatments they received and the length of their hospital stay were included. For statistical analysis, the distribution of the data was examined using the Kolmogorov-Simirnov test. Statistical analyzes were made with SPSS v.22 package program, the level of significance was taken into account as 0.05. 51 male and 51 female patients were evaluated in our study. The mean age of the patients was 56.51 ± 15.48 years. Average hospital stay was 7.58 ± 3.35 days. The patients were evaluated as longer and shorter hospitalizations than five days, and longer and shorter hospitalizations than seven days. Longer hospital stays were observed in patients with DM, HT, malignancy and those receiving favipravir, enoxaparin and vitamin C supplements. Fever, procalcitonin, AST and LDH values iv were found to be significantly higher in patients who were hospitalized for a long time compared to patients with a short hospitalization period. Lymphocyte count and percentage, neutrophil-lymphocyte ratio, monocyte count, mean platelet volume (MPV) lymphocyte ratio values were found to be significantly lower in long hospitalized patients.

Gold is another kind of investment that often experiences price change, mostly every day. Because of its price fluctuation, forecasting is needed to help the investor in investment decision making. But during this Coronavirus Disease 2019 (Covid-19), the gold price is fluctuating extremely than the past 4 years so a better forecasting method approached and analysis technique is needed due to this case. Double Exponential Smoothing method is chosen to forecast this daily gold price. On the other hand, there are so many missing values spreading around the main dataset so the imputation method is needed too, Last Observation Carried Forward (LOCF) and linear interpolation are chosen for imputing the missing values. In this research, the main dataset was split into 3 (three) datasets, which are Precovid-19 (before Covid-19, used only for visualizing the actual fluctuation condition during this pandemic), Incovid-19 (during Covid-19 based on the date where the first Covid-19 case occurred in Indonesia), and Combination (a binding dataset of Pracovid-19 and Incovid-19). Although Incovid-19's MAPE value is higher than Pracovid-19 and Combination's MAPE values, in evaluation session showed that Incovid-19's MAPE of forecast results has the lowest value rather than Combination's MAPE of forecast results, so the conclusion of this research is Incovid-19 dataset with LOCF imputation is the most adaptive with the actual condition and it is used to forecast the daily gold price until the last period of the main dataset then.

Abstract The issue of coronavirus outbreak in the world, though new, is equally pervasive. It has posed a new and ambiguous challenge to the economic growth of countries around the world. Undoubtedly, the efforts of countries to curb the spread of this virus and reduce the number of deaths are necessary for other strategies that will be taken in other areas, especially in the economic field. Comparing countries only based on the statistics on virus spread and mortality without considering the contextual variables, can be misleading. Thus using dynamic data envelopment analysis, this study calculated the performance of 19 selected countries in two dimensions: inefficiency of preventing coronavirus spread and inefficiency of preventing deaths caused by a coronavirus from February 2 to April 12. According to the study, the inefficiency trend of preventing coronavirus spread in Singapore, South Korea, China, and Australia are decreasing during the period under review and the inefficiency trend of other countries, which of course differ in terms of inefficiency, are increasing with different slopes. Also, Australia, Finland, Japan, Malaysia, Singapore, and Thailand have experienced less inefficiency in preventing deaths caused by coronavirus compared to other countries. Stringency index and global health security (GHS) index have been used as well, to analyze the findings and in the end some suggestions have been presented.

According to the World Health Organization (WHO), the Covid-19 pandemic has had a serious psychological impact on individuals. This also applies to teachers. Previous studies have also shown that 57% of teachers are considering changing their professions, which is partly because their well-being has been deteriorating. Positive psychology, in turn, has received more attention when it comes to students' well-being. The aim of this study is to investigate what role positive psychology can play in the promotion of teachers' well-being, with a specific focus on the well-being after the COVID-19 pandemic. Six (6) teachers in basic education in Finland participated in the study. They were interviewed through semi-structured interviews. The interviews were taped, transcribed and analyzed through a hermeneutic analysis method. The results showed that all teachers were affected by the Covid-19 pandemic and distance learning, although not all of them thought so themselves. What affected the teachers the most was the lack of social interaction and loneliness that the pandemic brought. The results also showed that the teachers in this study had good practices when it came to promoting their own well-being. These methods can be classified as methods belonging to positive psychology. Although teachers did not have good knowledge of what the concept of positive psychology means, these methods were used unconsciously. Enligt Världshälsoorganisationen (WHO) har Covid-19 pandemin haft allvarlig psykisk påverkan på individer, vilket även gäller lärare. Tidigare studier har även visat att 57% av lärarna funderar på att byta yrke, vilket delvis beror på att deras välbefinnande har försämrats. Positiv psykologi i sin tur har fått mera uppmärksamhet då det kommer att öka elevernas välbefinnande. Syftet med denna avhandling är att ta reda på vilken roll positiv psykologi kan spela då det kommer till att främja lärares psykiska välbefinnande, med speciell fokus på måendet efter COVID-19 pandemin. I studien deltog sex (6) lärare inom den grundläggande utbildningen i Finland. De intervjuades genom semi-strukturerade intervjuer, som bandades in, transkriberades och analyserades genom en hermeneutisk analysmetod. I resultaten framkom det att samtliga lärare påverkades av Covid-19 pandemin och distansundervisning, fastän inte alla själva ansåg det. Det som påverkade lärarna mest var avsaknaden av det sociala sammanhanget och ensamheten som pandemin förde med sig. Resultaten visade även att lärarna i denna studie hade goda strategier då det kom till att främja sitt välbefinnande. Dessa metoder kan klassificeras som metoder som hör till den positiva psykologin. Fastän lärarna inte hade goda kunskaper i vad begreppet positiv psykologi innebär så använde de ändå dessa metoder omedvetet.

At present, COVID-19 is raging all over the world. Many comorbidities, such as diabetes mellitus (OR = 2.67, 95% CI = 1.91–3.74) and hypertension (OR = 2.3, 95% CI = 1.76–3.00), have been shown to worsen the patient’s condition. However, whether cardio-cerebrovascular disease will affect COVID-19 remains unclear. In this meta-analysis, we collected studies from PubMed, Wed of Science and CNKI (Chinese) to July 25, which reported COVID-19 patients with and without cardio-cerebrovascular disease as well as their severity and mortality. The random-effect model meta-analysis was used to analyze them and get overall odds ratios (OR) with 95% CIs. Funnel plots and the Begg’s and Egger’s test were used to assess publication bias. Thirty-one studies with 23,632 patients were finally included in the meta-analysis. The results showed an OR of 3.004 (95% CI = 2.097–4.303) for COVID-19 severity and an OR of 5.587 (95% CI = 2.810–11.112) for COVID-19 mortality. Compared with cardiovascular disease, the subgroup analysis indicated that cerebrovascular disease was more likely to increase the severity (OR = 3.400, 95% CI = 1.569–7.368) and mortality (OR = 23.477, 95% CI = 3.050–180.735) of COVID-19. Therefore, it can be inferred that cardio-cerebrovascular disease is associated with an increase in the risk of severe illness and death among COVID-19 patients. This meta-analysis showed that cardio-cerebrovascular disease has a significant relation with severe and death outcomes of COVID-19. Nurses should pay special attention to COVID-19 patients with the cardio-cerebrovascular disease.

This paper describes the following major difficulties faced by the Endoscopic Examination Service of the Filatov’s State Clinical Hospital 15 during re-profiling into a COVID-19 specialized hospital: staff shortage and difficulties in personal protective gear work. The measures that have been taken with regard to the endoscopic examination service are specified in detail: cease of scheduled endoscopic examinations, strengthening of endoscopic teams with additional staff during complex manipulations, rejecting the use of fiber optic devices. Results of examinations carried out including hemorrhaging endoscopic papillotomy, lithoextrac-tion, and endoscopic hemostasis have been described. It was concluded that as a result of the reforms carried out, the endoscopic service was able to fulfill completely the assigned tasks.

With the COVID-19 pandemic, the pharmaceutical companies have been forced to shift their focus on digital marketing and targeting their customers in a more personalized manner. Due to the strict regulations of the pharmaceutical industry and the complexity created by these regulations, the digital marketing approach has not been applied to its fullest extent earlier. Finding and using optimal and appropriate medium in delivering promotions and right information to the customers has become a challenge for the pharmaceutical companies along with digitalization and virtual interactions. The marketing activities concentrating to digitally focused approach has caused uncertainty on message resonance due to nuances getting lost in virtual engagements compared to face-to-face interactions. The physicians are to some extent dissatisfied towards pharmaceutical companies digital interactions, because the companies mainly offer promotional information about their products instead of education related to clinical practice desired by the physicians. The topic of this Master´s thesis is related to a real-life business need with a purpose to answer to the following research question: “What kind of an omnichannel solution model could work for a pharmaceutical company?”. The research question got answered by conducting a research which aim was to build an omnichannel model for customer interactions for a pharmaceutical marketing company, to test the model and reflect it back to existing theory as well as propose potential next steps to improve the model for the future use. As the omnichannel marketing aims to deliver consistent, integrated and personalized experience for the customer regardless of the used channel or device the constructive approach used in this thesis focused on providing and testing a solution for enhancing the customer engagement with relevant content offering by utilizing the channel offering used by the company. The constructed model fulfilled the set expectations and was proven to be functional and useful for the company. Due to confidentiality reasons the constructed model along with the functionality findings is classified and cannot be accessed by anyone outside the company. As the society is currently dismantling the restrictions set during the COVID-19 pandemic, the model needs to be adjusted to fit the hybrid collaboration with the company and its customers to be able to fully fit for the future interactions and business needs.
