Consumer purchasing decision making has been of great interest to researchers and practitioners for improving strategic marketing policies and gaining a competitive advantage in the market.Traditional market models generally concentrate on single individuals rather than taking social interactions into account. However, individuals are tied to one another with invisible bonds and the influence an individual receives from others, affects her purchasing decision which is known as word of mouth (WOM) effect. In this process, some people have greater influence on other consumers' buying decisions that are known as opinion leaders.A new evolving modeling approach, agent-based modeling enables researchers to build models where individual entities and their interactions are directly represented.In this paper, we aim to build an agent-based simulation model for a technological product in a monopolistic artificial market. In particular, we will try to assess the efficiency and profitability of different marketing strategies consisting of different price, promotion, quality levels and different number of targeted opinion leaders where consumers are subject to WOM effects . In the presence of WOM, product's quality is found to be the most significant factor affecting the profit of the company due to the positive WOM effect disseminated by the consumers.

Cinema and society are dependent of each other and even have an interactive structure. This interactive structure allows social changes and transformations to take place in cinema as well. Cinema, which is affected by society, is also influenced by national elements. Halit Refiğ, the pioneer of the "National Cinema" movement in the history of Turkish cinema, is an important director who argues that Turkish cinema should develop its own interpretation of the cinema. While Refiğ creates the theoretical background of the "National Cinema" movement, he defines his films as both content and form related to these ideas. In his films, he strives to create a unique form of cinema fits the Turkish society by focusing on the national values in his own cinema in the context of the East-West dilemma. This study investigates how the East-West dilemma was dealt with in the cinema of Refiğ, based on the films Bir Türk'e Gönül Verdim , Fatma Bacı and Vurun Kahpeye . This article investigates how Refiğ's films reflect his cinema tendency and that was analyzed according to a schema that adapted to the cinema and based on Teun A van Dijk's critical discourse analysis. As a result of this study, it is clearly determined that Halit Refiğ reveals the East-West dilemma in the researched three films.
