Published: April 2021

Exposure to UV (Ultraviolet) rays for a certain period can cause erythema, sunburn,photoallergies, and forms ROS (Reactive Oxygen Species) which leads to gene mutations,premature aging, and skin cancer. Skin cancer in Indonesia ranks third after cervical cancer andbreast cancer. Sunscreens can protect skin from UV exposure, although many sunscreens usechemicals that can cause contact dermatitis and other allergies. Various studies have shown thatplants with antioxidants can protect the skin from exposure to UV rays. Poinsettia (Euphorbiapulcherrima) is an ornamental plant with antioxidant properties. This literature review aims to examine the potential of the poinsettia as a sunscreen against UV rays. The extract of thepoinsettia leaf has the potential to be sunscreen against UV exposure because the antioxidantcontent of flavonoids and other photo protectors, inhibits ROS, thereby preventing mutations andthe process of ordering skin cancer. Antioxidants in poinsettia help heal burns and stimulatefibroblast to prevent premature photoaging due to excessive UV exposure. Conclusion, Kastubaleaf extract (Euphorbia Pulcherrima) has the potential as a sunscreen against UV exposure

Published: April 2021

The research subject includes the theoretical basis and mechanism of fiscal and monetary policy coordination. The study aims to justify the conceptual basis of fiscal- monetary policy interactions to ensure economic development. Methods. To achieve the appropriate tasks, we used a set of methods and approaches that helped ensure our investigation's conceptual unity. The systemic and structural approaches, analysis and synthesis methods, comparison, generalization, modeling, and scientific abstraction are applied. Results. In this paper, we improved the theoretical and methodological foundations of fiscal and monetary policy coordination. The author highlighted the necessity to use the institutional approach in that case. Also, we gave practical proposals to develop the system for assessing the effectiveness of the coordination of fiscal and monetary policy. Practical implications. Government economic policy and instruments of its implementation. Conclusions. Empirical experience has shown the advisability of fiscal and monetary policy coordination to ensure sustainable endogenous economic growth. Coordination of government financial policy measures in the context of the economic cycle stages should be based on an institutional approach. The interaction of fiscal and monetary policies should focus on increasing social welfare and the maintenance of long-term macroeconomic stability. The adaptive interaction of monetary and fiscal mechanisms and the improvement of the state's economic system's institutional architectonics contribute to the intensification of business entities' economic activity. Meanwhile, those factors positively influence on economy's competitiveness. The necessity of introducing a system for assessing the effectiveness of the coordination of fiscal and monetary policy determines effective measures of financial regulation at a certain stage of economic development.
Confidentiality and scam in the internet
Authors: Shulga Olga 
Published: April 2021

The purpose of the work is to consider the theoretical and practical aspects of fraud in the Internet sphere and on this basis to identify ways to ensure the confidentiality and cybersecurity of private users and commercial organizations. The methodological basis of the work is the use of general and special methods of scientific knowledge. Methods of combining analysis and synthesis, induction and deduction have been used to identify different types of fraud in the Internet. Generalization methods, logical and empirical, were used in determining the directions of development of the national cyber defense system and ensuring confidentiality. The main results of the work: The most common methods of fraud with the use of bank payment cards are identified, among which: a fake poll on social networks with a prize draw; a phone call to obtain classified information; SIM card replacement for access to online banking; online payments on unsecured sites; phishing; copying card data when handed over; unsecured WI-Fi networks; computers in public places; skimming for card data theft; unauthorized micropayments; ATM fraud; use of malicious programs (viruses), fake sites in order to compromise the details of electronic payment instruments and/or logins/passwords for access to Internet/mobile banking systems; dissemination (sale, dissemination) of information on compromised data; terminal network fraud; fraud in remote service systems; social engineering. Basic security rules are defined to prevent fraud. The experience of European countries in the field of cybersecurity is analyzed. The directions of adaptation of the current legislation on cybersecurity to the EU standards are outlined and the directions of development of the national system of cybersecurity are defined. The practical significance of the results is to deepen the understanding of the nature and mechanism of various types of fraud in the Internet. The recommendations proposed in the paper can form a methodological and theoretical basis for the development of economic policy of the state to ensure the confidentiality and cybersecurity of private users and commercial organizations. Conclusions. The state should establish an effective oversight body in the field of personal data protection, but security measures and online restrictions should comply with international standards. The use of encryption should not be prohibited at the legislative level, as such restrictions reduce the ability of citizens to protect themselves from illegal intrusions into privacy. In addition, the state policy in the Internet should be aimed at promoting the development and operation of secure Internet technologies and the formation of mechanisms to protect against services and protocols that threaten the technical functioning of the Internet from viruses, phishing and more.
Simulation of the assessment of the competitiveness of sea ports of Ukraine using the Harrington function
Authors: Kudrytska Natalia 
Published: April 2021

Relevance of the research topic. The article is devoted to the problem of assessing the competitiveness of seaports of Ukraine, the relevance of which is highlighted in the National Transport Strategy of Ukraine for the period up to 2030; Strategies for the development of seaports of Ukraine for the period up to 2038; Corporate strategy of the state enterprise "Administration of Seaports of Ukraine" until 2025. Analysis of recent research and publications. The article provides an overview of modern foreign publications on assessing the competitiveness of seaports using various methods, in particular: the Herfindahl-Hirschman index; psychometric Likert scale; expert assessments based on an extended version of M. Porter's "diamond" approach. Selection of unexplored parts of the general problem. The author emphasizes the inadequacy of domestic work on assessing the competitiveness of seaports using economic and mathematical modeling. Problem statement, research goals. The aim of the article is to implement a methodological approach to assessing the competitiveness of Ukrainian seaports using the Harrington desirability function. Method or methodology of the study. The methodological basis of the study is the methods of economic and mathematical modeling. Presentation of the main material. In modern economic conditions, the seaport is considered a complex economic system. One of the most convenient and clear methods of solving multicriteria problems, which include the assessment of competitiveness, is the desirable function of Harrington. The author simulates the assessment of the level of competitiveness of 13 seaports of Ukraine using the psychophysical scale of Harrington's desirability on the basis of these indicators that characterize their technical condition. Conclusions in accordance with the article. As a result of modeling, it was obtained that the generalized coefficient of desirability of assessing the competitiveness of Ukrainian seaports has a value in the range from 0.42 to 0.77, ie the assessment of "satisfactory" and "good". This means that the modernization of ports, which helps to improve these indicators (number of berths, their length, maximum depth of parking near berths, the total area of warehouses) can significantly increase the level of their competitiveness.
