Background: Serbia is one of the countries with highest incidence and mortality rates for cervical cancer in Central and South Eastern Europe. Introducing a risk index could provide a powerful means for targeting groups at high likelihood of having an abnormal cervical smear and increase efficiency of screening. The aim of the present study was to create and assess validity ofa index for prediction of an abnormal Pap test result. Materials and Methods: The study population was drawn from patients attending Departments for Women's Health in two primary health care centers in Serbia. Out of 525 respondents 350 were randomly selected and data obtained from them were used as the index creation dataset. Data obtained from the remaining 175 were used as an index validation data set. Results: Age at first intercourse under 18, more than 4 sexual partners, history of STD and multiparity were attributed statistical weights 16, 15, 14 and 13, respectively. The distribution of index scores in index-creation data set showed that most respondents had a score 0 (54.9%). In the index-creation dataset mean index score was 10.3 (SD-13.8), and in the validation dataset the mean was 9.1 (SD=13.2). Conclusions: The advantage of such scoring system is that it is simple, consisting of only four elements, so it could be applied to identify women with high risk for cervical cancer that would be referred for further examination.

The chemical composition of essential oils obtained from the roots, stems, and leaves of Ballota nigra, growing in Serbia, was investigated by gas chromatography/mass spectrometry analyses. Kovats indices, mass spectra, and standard compounds were used to identify a total of 115 individual compounds. The plant produces two types of essential oils. Oils derived from stems and leaves were sesquiterpene rich (78.17% and 88.40%, respectively), containing principally $\beta$-caryophyllene, germacrene D, and $\alpha$-humulene, present in appreciable amounts. In contrast, oil derived from the root was dominated by p-vinylguiacol (9.24%), borneol (7.51%), myrtenol (7.13%), trans-pinocarveol (5.22%), pinocarvone (4.37%), 2-methyl-3-phenylpropanal (4.32%), and p-cymen-8-ol (4.30%). Essential oil obtained from the roots was evaluated for the antimicrobial activity against seven bacterial species and one fungi.

Series of imino and amino derivatives of 4-hydroxy coumarins were synthesized via conventional and microwave promoted procedure and evaluated for antioxidant potential through different in vitro models such as (DPPH) free radical scavenging activity, linoleic acid emulsion model system, reducing power assay and phosphomolybdenum method. All prepared compounds possess good antioxidant activity and among them p-nitro-phenyl derivative 6c with IC50 at 25.9 μM possesses radical scavenging activity which is comparable to standard BHT, while the best reducing power was observed in a case of benzyl amino compound 8c (RP50 255.6 μM). Also, observed data indicated that compounds may serve as inhibitors of lipid peroxidation process.
Mobile Robot Motion Framework Based on Enhanced Robust Panel Method
Jasmin Velagic,Lamija Vukovic,Belma Ibrahimovic 제어·로봇·시스템학회 2020 International Journal of Control, Automation, and Vol.18 No.5
This paper proposes a framework for the mobile robot motion in partially unknown static and dynamic environments. Its main part is a path planner which is based on the enhanced robust panel method (ERPM). This proposed method improves an existing panel method in order to be employed for moving obstacles represented as open polygonal chains. The robustness of the proposed method is provided due to the automatic adjustment of the potential field parameters. Therefore, the proposed path-planning strategy incorporates relevant obstacle pruning and activation window algorithms to speed up the overall navigation process. Furthermore, the modified Histogramic-In-Motion-Map (MHIMM) method is proposed to continuously update a grid-based map of the environment. The path planning and robot motion performance evaluation with respect to the sensor noise and different environments is done using various metrics. The effectiveness and robustness of the proposed motion frameworkare demonstrated through numerous realistic scenarios within ROS environment with Pioneer 3DX mobile robot.

Since its early stages, the coronavirus disease 2019 (COVID-19) pandemic has posed immense challenges in meeting the public health and healthcare and social care needs of migrants. In line with other reports from United Kingdom and United States, data from Sweden’s health authority show that migrants have been disproportionately affected by COVID-19. Following the World Health Organization’s statements, as well as the European Public Health Association’s call for action, several centres in Sweden’s most populated areas have activated tools to implement national plans for community outreach through initiatives targeting migrants and ethnic minority groups. Unconventional means should be promoted to mitigate the impact of COVID-19 on migrants and the health of the public at large.

Background: In the etiology of cervical cancer not only HPV infection is important, but also other factors such as demographic influences andsexual and reproductive health attitudes, as well as others related to preventive measure usage (or non usage). The aim of this study was to examine factors associated with cervical dysplasia in asymptomatic women who were examined by routine cytology and cervical biopsy for early detection of cervical cancer. Materials and Methods: Socio-demographic and other characteristics were obtained from medical files of 85 examinees with pathologic cytologic findings (Pap test) and histopathologic (HP) findings after biopsy. Results: ccording to the Pap test result, a greater probability for development of cervical dysplasia was noted with examinees having a larger number of sexual partners (OR= 5.01, 95% CI 1.04-24.10), and those who are afraid of the Pap finding. Risk factors for development of cervical dysplasia according to the bioptic finding were early beginning with sexual activities, presence of any STD in personal medical history and fear of the Pap test finding. Conclusions: The only risk factor found to be important for both methods was fear of the Pap testing finding.
Lightweight and adaptable solution for security agility

Secure communication is an important aspect of today`s interconnected environments and it can be achieved by the use of cryptographic algorithms and protocols. However, many existing cryptographic mechanisms are tightly integrated into communication protocols. Issues emerge when security vulnerabilities are discovered in cryptographic mechanisms because their replacement would eventually require replacing deployed protocols. The concept of cryptographic agility is the solution to these issues because it allows dynamic switching of cryptographic algorithms and keys prior to and during the communication. Most of today`s secure protocols implement cryptographic agility (IPsec, SSL/TLS, SSH), but cryptographic agility mechanisms cannot be used in a standalone manner. In order to deal with the aforementioned limitations, we propose a lightweight cryptographically agile agreement model, which is formally verified. We also present a solution in the Agile Cryptographic Agreement Protocol (ACAP) that can be adapted on various network layers, architectures and devices. The proposed solution is able to provide existing and new communication protocols with secure communication prerequisites in a straightforward way without adding substantial communication overhead. Furthermore, it can be used between previously unknown parties in an opportunistic environment. The proposed model is formally verified, followed by a comprehensive discussion about security considerations. A prototype implementation of the proposed model is demonstrated and evaluated.
