Preserving location privacy is increasingly an essential concern in Vehicular Adhoc Networks (VANETs). Vehicles broadcast beacon messages in an open form that contains information including vehicle identity, speed, location, and other headings. An adversary may track the various locations visited by a vehicle using sensitive information transmitted in beacons such as vehicle identity and location. By matching the vehicle identity used in beacon messages at various locations, an adversary learns the location history of a vehicle. This compromises the privacy of the vehicle driver. In existing research work, pseudonyms are used in place of the actual vehicle identity in the beacons. Pseudonyms should be changed regularly to safeguard the location privacy of vehicles. However, applying simple change in pseudonyms does not always provide location privacy. Existing schemes based on mix zones operate efficiently in higher traffic environments but fail to provide privacy in lower vehicle traffic densities. In this paper, we take the problem of location privacy in diverse vehicle traffic densities. We propose a new Crowd-based Mix Context (CMC) privacy scheme that provides location privacy as well as identity protection in various vehicle traffic densities. The pseudonym changing process utilizes context information of road such as speed, direction and the number of neighbors in transmission range for the anonymisation of vehicles, adaptively updating pseudonyms based on the number of a vehicle neighbors in the vicinity. We conduct formal modeling and specification of the proposed scheme using High-Level Petri Nets (HPLN). Simulation results validate the effectiveness of CMC in terms of location anonymisation, the probability of vehicle traceability, computation time (cost) and effect on vehicular applications.

Cloud computing is hosted technology used to deliver services over internet. These services are broadly classified based on type of hosting i.e. infrastructure, platform and software. Public environment and internet connectivity make it vulnerable and unsafe for communication and storage. Confidentiality is one of the major principles to keep data privacy and protection at high level. Cryptographic techniques are used to achieve confidentiality and integrity of information during unsafe communication. This research paper observes that various cryptographic algorithms known as symmetric key cryptography and asymmetric key cryptography can be used to protect information and make it unreadable for unauthorised users. This research paper implements different security algorithms and observe their performance based on computation time over different input sizes. The complete research work concludes a comparative study and recommends different security approaches for different situations.

This article describes a crucial and fundamental stage in the transformation of Hebrew children's literature, during the late 1930s and 1940s, from a single channel of expression to a multi-layered polyphony of models and voices. It claims that for the first time in the history of Hebrew children's literature there took place a doctrinal confrontation between two groups of taste-makers. The article outlines the pedagogical and ideological designs of traditionalist Zionist educators, and suggests how these were challenged by a group of prominent writers of adult poetry, members of the Modernist movement. These writers, it is argued, advocated autonomous literary creation, and insisted on a high level of literary quality. Their intervention not only dramatically changed the repertoire of Hebrew children's literature, but also the rules of literary discourse. The article suggests that, through the Modernists’ polemical efforts, Hebrew children's literature was able to free itself from its position as an apparatus controlled by the political-educational system and to become a dynamic and multi-layered field.

The centenary of the Ukrainian Revolution (1917―1921s) made relevant the interest to the developments and the personalities of that time, specifically, to the personality of the President of the ZUNR, Petrushevych, Yevhen. The newspaper «Ukrayinskyi Prapor» founded in 1919 in Vienna, throughout its existence, was considered as an official print organ of the Dictator (i.e., Y. Petrushevych). The Vienna period of this publication lasted from August 1919 to mid-November 1923. From the end of November 1923 till April 1932, the paper was published in the capital of the Weimar Republic, Berlin. It was the only newspaper of the Ukrainian emigration published for the longest time in interwar Germany. It was an example of a socio-political periodical. There collaborated outstanding editors and publicists. The pages of this paper record the history of the diplomatic struggle of the West Ukrainian foreign representatives for the liberation of the Eastern Galicia from the protectorate of Poland and the restoration of Ukrainian statehood. Its materials documented the course of the occupation of the Eastern Galicia by Poland and the process of «Polonization» of the Ukrainian population of that region. The article explores the Berlin period of existence of the magazine. Specifically, it studies the changes in the ideological line of the magazine, more specifically, its pro-Soviet editorial orientation because of the illusions about the transformation of the national policy of the Soviet rule in Ukraine, especially during the period of Ukrainization. Then the traditional headings of the magazine were joined by the publications with positive coverage of the flourishing Ukrainianization in Soviet Ukraine. The newspaper also actively reacted to the SVU (Union for Liberation of Ukraine) trial in Kharkiv, justifying the position of the Soviet authorities. The paper’s editorial staff were well-known figures of Ukrainian politics, science, and culture: Yu. Bachynsky, O. Hrytsai, A. Zhuk, M. Lozynsky, R. Perfetsky, and others. They provided a high level of editorial content with high-quality, multifaceted texts. We conclude that in terms of the editorial content and formal aspects, the newspaper «Ukrayinskyi Prapor» matched the standards of the European mainstream press of that time.

Background: According to the new classification criteria developed by The Assessment of SpondyloArthritis International Society, patients with axial spondyloarthritis (axSpA) can be classified in 2 subgroups: Patients with radiographic axial spondyloarthritis: ankylosing spondylitis patients (AS) and those with non-radiographic axial spondyloarthritis (nr-axSpA). Objective: The aim of the present study is to describe and discuss the differences and similarities between the two subgroups. Patients and Methods: A cross-sectional study was conducted in a single rheumatology hospital in Morocco. These included patients diagnosed as having axial spondyloarthritis according to ASAS criteria 2010, during a period of 6 years. The AS and the nr-axSpA subgroups were compared for the various axSpA-related variables. Results: Of the 277 patients with a diagnosis of axial SpA who were included in this study, 160 had AS and 117 had nr-axSpA. AS and nr-ax-SpA shared a similar age at diagnosis, similar prevalence of low back pain, lumbar stiffness, extra-articular manifestations, BASDAI and BASFI. In the multivariate analysis, AS patients were mainly male with cervical stiffness, enthesitis, coxitis and high level of ESR (erythrocyte sedimentation rate). The females generally had a family history of SpA and arthritis and were associated to the nr-axSpA form in the univariate analysis. Conclusion: This was the first study to characterise patients with AS and nr-axSpA in Morocco. Consistent with other studies published, this study showed that patients with nr-axSpA and patients with AS shared a comparable degree of disease burden.

We investigated the COVID-19 vaccination acceptance level in Azuay province, Ecuador through an online survey from 12th to 26th February (before the start of the COVID-19 vaccination campaign in Ecuador). Overall, 1219 respondents participated in the survey. The mean age was 32 ± 13 years; 693 participants (57%) were female. In total, 1109 (91%) of the participants indicated they were willing to be vaccinated with a COVID-19 vaccine, if the vaccine is at least 95% effective; 835 (68.5%) if it is 90% effective and 493 (40.5%) if it is 70% effective; 676 (55.5%) participants indicated they feared side effects and 237 (19.4%) thought the vaccine was not effective. Older age, having had a postgraduate education, a history of a negative COVID-19 test, a high level of worry of contracting COVID-19, believing that COVID-19 infection can be prevented with a vaccine and understanding there is currently an effective vaccine against COVID-19 were associated with higher vaccination acceptance. A vaccination education campaign will be needed to increase the knowledge of Ecuadorians about the COVID-19 vaccine and to increase their trust in the vaccine. People with a lower education level and living in rural areas may need to be targeted during such a campaign.

The aim of this research was to conduct a risk assessment and management of psychological, structural, social and economic determinants (PSSED) in a suicide attempt. The sample consisted of 353 individuals who had a recorded history of suicidal attempt; and 20 professional individuals by purposive sampling method within a descriptive cross-sectional design. Worksheets for RAM and AHP were used for data collection in this study. The rate of suicide attempt was 7.21 per 100,000 population in this study. Analysis showed that depression and mental disorders; personality disorders; family problems; socio-cultural and economic problems; lack of awareness; and low level of education have a high level of risk for suicide attempts. Psychiatric and psychological services; awareness and knowledge of life skills; medical services to dysfunctional families; development of community-based planning for PSSED of suicide; and employment and entrepreneurship services may lower suicide attempt risk.

Mormon studies in China began in the early 1990s and can be divided into three phases between the years of 2004 and 2017. The first Master’s and Doctoral theses on Mormonism were both published in 2004, and journal articles have also been increasing in frequency since then. The year of 2012 saw a peak, partly because Mormon Mitt Romney won the Republican nomination for the 2012 US presidential election. In 2017, a national-level project, Mormonism and its Bearings on Current Sino-US Relations, funded by the Chinese government, was launched. However, Mormon studies in China is thus far still in its infancy, with few institutions and a small number of scholars. Academic works are limited in number, and high-level achievements are very few. Among the published works, the study of the external factors of Mormonism is far more prevalent than research on its internal factors. Historical, sociological, and political approaches far exceed those of philosophy, theology, and history of thoughts. To Mormon studies, Chinese scholars can and should be making unique contributions, but the potential remains to be tapped.

AbstractFatty liver index (FLI), a predictor of nonalcoholic fatty liver disease, has been reported to be associated with several metabolic disorders. This study aimed to evaluate the relationship between FLI and new onset of diabetes mellitus (DM). We investigated the association of FLI with new onset of DM during a 10-year period in subjects who received annual health examinations (n = 28,990). After exclusion of subjects with DM at baseline and those with missing data, a total of 12,290 subjects (male/female: 7925/4365) who received health examinations were recruited. FLI was significantly higher in males than in females. During the 10-year period, DM was developed in 533 males (6.7%) and 128 females (2.9%). Multivariable Cox proportional hazard models with a restricted cubic spline showed that the risk of new onset of DM increased with a higher FLI at baseline in both sexes after adjustment of age, fasting plasma glucose, habits of alcohol drinking and current smoking, family history of DM and diagnosis of hypertension and dyslipidemia at baseline. When the subjects were divided into subgroups according to tertiles of FLI level at baseline (T1–T3) in the absence and presence of impaired fasting glucose (IFG), hazard ratios after adjustment of the confounders gradually increased from T1 to T3 and from the absence to presence of IFG in both male and female subjects. In conclusion, a high level of FLI predicts new onset of DM in a general population of both male and female individuals.
