Objectives : Plastic pollution is a very important environmental issue in Korea as well as abroad. The objective of this study is to evaluate the internal and external factors that cause pollution of the coastal environment of Jeju Island using styrene oligomers (SOs) originated from polystyrene (PS) plastic.Methods : In order to achieve the above objective, this study is conducted to quantitatively measure the concentration of 12 individual SOs chemicals, through gas chromatography/mass spectroscopy (GC/MS) analyzing seawater and beach sand samples around sandy beaches in Jeju Island. This study evaluates the degree of environmental pollution according to internal or external factors of the sandy beach by using the physicochemical characteristic that SOs species are adsorbed on the surface of sand particles.Results and Discussion : The average concentration of SOs in the beach sand of Jeju Island ranges from a minimum of 9.80 ng/g to a maximum of 13.62 ng/g, and the average concentration of SOs in seawater is relatively low with a constant 0.05 to 0.11 µg/L. Although the concentration distribution of SOs species differs considerably depending on the sample collected, the concentration of SOs decreases in the order of styrene trimers (7 isomers) > styrene dimers (4 isomers) > styrene monomer. As a result of monitoring, the concentration of SOs at the sandy beaches of Jeju Island is much higher in the beach sand than in the seawater. This result means that the major beaches of Jeju Island can be polluted mainly by internal factors (e.g. population density, number of travelers according to population movement, and so on), because SOs species are adsorbed on the surface of the sand particles and their mobility is limited.Conclusions : This study shows that the sandy beaches of Jeju Island are mainly polluted by internal factors. It is thought that the pollution degree of the sandy beaches is the highest in the order of Gwakji Beach < Samyang Beach, Hamdeok Beach, Pyoseon Beach < Ihoteho Beach, Sagye Beach < Seopjikoji Beach, Gimnyeong Beach, and Hyeopjae Beach. This study is expected to contribute to the evaluation of the causes of plastic pollution in the coastal environment of Jeju Island.

The distribution of heavy metal concentrations in the beach sand samples collected from 44 different locations along the Manavgat Alanya coastline of Antalya covering different coastal sandy beaches was studied. The average concentration level of these metals in the beach sand was calculated and compared to those of the Earth Crust, Sandstone, Ultrabasic Rock and the acceptable limit for Turkey in order to determine their anomalies. Heavy metal (Cr, Zn, Ni, As, Cu, Pb, Co, Mo, Sb and Cd; along with Al, Fe, Mg, Mn, Na, K, Ba, Ca and W) were determined. The elements occurred in abundance as Ca>Na>Mg>Fe>Al>K>Ti>Mn>Cr>Ba>V>Zn>Ni>As>Cu>Pb>Co>Mo>Sb>W>Cd. The sufficiency of the number of samples used from the study area is revealed by the high explanatory power R2 = 96:9 % of the ANOVA Model. Using the box plot, it was also noted that some heavy metals such as As (in samples 1, 19, 25, 28 and 29); Mn (in Samples 23 and 39); Na (in samples 23, 24 and 45); Cr (in Sample 33) and Ti (in Sample 15) had very high anomalies. Heavy metal contents show high anomaly concentrations when compared to some background values (Earth Crust, Sandstone, Ultrabasic and Turkey acceptable limit).

All innovative products implemented by enterprises can be classified into two categories: radical innovation or improvements. If the first category is almost exclusively the result of breakthrough scientific research, then the second is a consequence of management actions to further improve previous innovative products. Improvements, in contrast to radical innovations, are a relatively less studied direction. In most cases, the moment the radical innovations enter the market is difficult to predict. However, the introduction of improvements to the market is determined by management. At the same time, management, making a decision on introducing an innovative product to the market, focuses on internal and external factors. Internal factors are organizational readiness to introduce an innovative product, and external factors are market necessity. The latter implies, if possible, a reaction to the actions of competitors, who also introduce innovations. The problematic question remains relevant: how do various external and internal factors determine the choice of the moment the innovation is brought to the market. What has a decisive influence on such a strategic choice? The purpose of this study was to investigate how competing and complementary technological events in the environment affect an enterprise’s launch of innovative products on the market. The study was carried out based on the analysis of scientific publications on the economics of innovation and publications on competitive rivalry. The main conclusion: strategies for improvements, as a rule, become less focused on the internal determinants of bringing innovations to the market as market concentration increases, and at the same time, they are increasingly reacting both to competitors’ innovations and innovations in additional technologies. Thus competitive pressure in the industry is an important determinant of the strategic choice to bring innovation to the market.

This chapter deals with the sedentary dialects of Egypt, excluding the bedouin dialects of Sinai and the Libyan bedouin dialects on the Mediterranean coast. It attempts to combine historical information on the settlement of Arabic tribes in Egypt with accounts of present-day Egyptian dialects and those of the regions from which those tribes came, initially Yemen and the Levant, later Hejaz, and then the Maghreb. The diversity of the Egyptian Arabic dialect area is partly explained by external factors, namely different layers of arabization over centuries. It is also explained by internal factors, namely dialect contact, which implies phenomena such as hyperdialectisms. Egypt is seen as a dialect area in its own right, but one that shows phenomena of a transitional area between the Arab East and West. A case study of Alexandria deals with dialect death. The role of substrata is discussed, but is considered negligible.

This article discusses the problem of choosing the correct and effective organizational structure of enterprise management for its correct functioning. The existing types of organizational structures of enterprise management, which are used in practice today, are analyzed, and their positive, negative sides and the type of enterprises for which they can be used are revealed. Along with this, this article discusses and describes methods for choosing an organizational structure for an enterprise. Also, during the study, internal and external factors were identified that affect the choice of an organizational structure. Based on the analysis, a methodology for choosing the most effective type of organizational structure for enterprises was drawn up. The question of choosing an organizational structure is acute for every manager at the very beginning of the operation of an enterprise, because the quality of performance of functions, both of individual divisions and of the entire enterprise as a whole, directly depends on this. Among many types of organizational structures in this study, the types of organizational structures that are most adaptable to changes in external and internal factors are identified. This study provides methods and tools for selecting the appropriate organizational structure for any enterprise. At the moment, some methods, be it goal structuring or computer modeling, are not widely used, which in turn makes it difficult to choose an effective organizational structure for enterprise management. The choice of an effective organizational structure is an extremely urgent problem today for every entrepreneur, who is interested in the stable economic activity of his or her enterprise.
