AbstractBackgroundThe infectious respiratory disease COVID-19, caused novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reached pandemic status during 2020. The primary statistic data are important to survey the actual circumstances of COVID-19. Here, we report the analysis of the primary data of COVID-19 in Japan during 2020.MethodsData were collected and released systematically under Japan domestic law. Machine learning was conducted to estimate the positive rate in Japan and four prefectures (Tokyo, Osaka, Chiba, and Fukuoka).ResultsPrimary data analysis revealed there were at least two peaks of infection in Japan; the first one was during April 2020 and the second one started from November 1, 2020. Estimating the positive rate in Japan as well as in the four prefectures reinforced the above observations. The positive rate in Japan during 2020 was estimated to be around 6% to 8%. We also estimated that 1.95 million people were possibly exposed to the novel virus on October 31, 2020. The numbers of related deaths were over 3,000 people at the end of 2020.ConclusionWe estimated the infection rate of SARS-CoV-2 in Japan to be 6–8% in 2020. We also concluded that Japan had at least two infection-spreading periods, the first one being from Jan 19, 2020 until May 2020, and the second one beginning from November 1, 2020. Importantly, our analysis supports the need for clear definition of the criteria for conducting confirmation tests before embarking on data analysis.

The use of online shopping agents has increased dramatically in the last 10 years, as a result of e-commerce development. Despite the importance of these online applications, very few studies attempted to identify and analyse the main factors that influence the users’ perception regarding the service quality of online shopping agents, and consequently, the elements that determine the users’ choice of online shopping agents. The present study attempts to fill this literature gap, identifying on the basis of primary data analysis, the various circumstantial or personal factors that can determine the choice of a specific searching strategy and shopping agent.

This study wanted to determine the factors that caused the accumulation of year-end budgets in the DP2KBP3A Bangka Regency for the 2017-2019 fiscal year. The data sources are field studies and documentation in related offices at the Bangka Regency Regional Work Unit. Based on the primary data analysis and discussion of the results, we report that the causes of budget accumulation are, among others, still more dominant, characterized by item line systems, incremental, rigid, overlapping, conflicts of interest, motives for seeking personal and group benefits, budget wastage, and does not provide benefits for improving the performance of the apparatus and public services. The factors for the procurement of goods/services related to the procurement of goods/services are the lack of knowledge about the regulations in the process of procuring goods/services, the weak management commitment of the SKPD head, and the commitment of the employees involved in the procurement of goods/services. The process of procuring goods/services and the SKPD environment is not yet conducive to coordination and teamwork. Other problems include the human resource deficit that manages finances. We hope that this result will be a valuable input for developing the following study.

The article highlights the problem of defining the concept of «indigenous people» in international and domestic (local) law. It is found that the current practice of defining them still retains some difficulties due to the lack of a clear, unified and formally fixed definition of these peoples at universal legal level. Particular attention is given to the study of existing approaches to their definition used at domestic (local) level. A proposal is made that there is a necessity to rethink concept of defining «indigenous people». Authors in the research understand the recognition of these ethnic communities as autonomous subjects of international and domestic (local) law. Based on the data analysis, it was concluded that the current practice of defining indigenous peoples are highly variable greatly depending on the features of each state. At the same time, it still reveals a certain coherence based on historical and cultural assumptions.
