The phase model of market economy is suggested in the article. It is formalized in the cubical equation The equation takes into account the imperfections of competition and the fact that consumer goods are produced with the help of means of production. Transitions from the imperfect competition to the perfect one and visa versa yield qualitative status change of market economy.

Assurance Process

Ports in the transport economy have an important role to play in the competitiveness of ports. There is an increasing climate of competition, which causes ports to invest in development and to improve their transport corridors, governance principles and pricing policies in order to strengthen international competitiveness of ports and to ensure that their management practices are in line with the positive international experience. In order to increase the efficiency of transport, to promote the use of environmentally friendly technologies and to improve the international competitiveness of port transport corridors, it is important for ports to determine their own KPI indicators that would be used to assess port performance indicators. As ports are responsible for the quality assurance of port services, even if they do not provide such services, monitoring and assessing of the KPI must be part of the quality assurance process. The objective of this study is to define the port performance-enhancing KPI indexes and to make suggestions for how KPI application in the transport economy can strengthen the international competitiveness of ports and ensure that their management practises international experience. The study’s tasks are to define the appropriate KPI indexes, group them according to interlinked principles, and provide proposals on how to use them to improve the international competitiveness of ports and the main transport system multimodal integration.

Abstract - Laser-Induced Breakdown Spectroscopy (LIBS) is one method of atomic emission spectroscopy using laser ablation as an energy source. This method is used to characterize the type of amethysts that originally come from Sukamara, Central Kalimantan. The result of amethyst characterization can be used as a reference for claiming the natural wealth of the amethyst. The amethyst samples are directly taken from the amethyst mining field in the District Gem Amethyst and consist of four color variations: white, black, yellow, and purple. These samples were analyzed by LIBS, using laser energy of 120 mJ, delay time detection of 2 μs and accumulation of 3, with and without cleaning. The purpose of this study is to determine emission spectra characteristics, contained elements, and physical characteristics of each amethyst sample. The spectra show that the amethyst samples contain some elements such as Al, Ca, K, Fe, Gd, Ba, Si, Be, H, O, N, Cl and Pu with various emission intensities. The value of emission intensity corresponds to concentration of element in the sample. Hence, the characteristics of the amethysts are based on their concentration value. The element with the highest concentration in all samples is Si, which is related to the chemical formula of SiO2. The element with the lowest concentration in all samples is Ca that is found in black and yellow amethysts. The emission intensity of Fe element can distinguish between white, purple, and yellow amethyst. If Fe emission intensity is very low, it indicates yellow sample. Thus, we may conclude that LIBS is a method that can be used to characterize the amethyst samples.Key words: amethyst, impurity, laser-induced, breakdown spectroscopy, characteristic, gemstones
