Abstract:
Purpose – The present study aims to explore the motives behind social media (SM) use. Methodology/Approach/Design- The prominent studies on social media use have been examined theoretically, classified in detail regarding SM types, and inferences have been made. In this context, the study is a literature review. Findings- The most emphasized SM sites in the lit-erature are Twitter, Instagram, Facebook, TikTok, Snapchat, LinkedIn and YouTube. SM networking sites have usage differences depending on users’ age and purpose. Motives behind the SM use are mostly explained by the uses and gratification ap-proach. The most emphasized motives in SM use are social interaction, entertainment and infor-mation seeking. Finally, the effects of social mo-tives are higher than individual motives in social media use. Originality/Value- With this study, it is expected to contribute to the field by drawing a profile on SM use and increasing the knowledge about the motives that push individuals to use SM.

Abstract:
As the rapid development of communication and information technologies allows real-time transmission of information, the world is increasingly becoming a global society. In this context, the most developed countries are required to develop their own strategies to encourage the industrial sector to stay up to date and compete in a dynamic and volatile global market in order to maintain its competitive capacity. For this reason, since the path of competitiveness through technological differentiation in industrialization provides a wider and innovative field of research, it reveals the result of a new phase of organization and industrial technology that is beginning to change our relationship with industry, society and human interaction in the business world at present standards. The main target of this study is to reveal the effects of Industry 4.0 on the Maritime sector using with the explanation of the historical development and conceptual framework of today's high technology industry 4.0 and its expectations in maritime sector in the light of the relevant literature. The whole worldwide maritime applications and their reflections on all fields are also the scope of this study. A qualitative descriptive analysis method was conducted to determine the current situation of Maritime Sector which is including Industry 4.0 processes. The findings of this study are Marine-related organizations should be reshaped to meet the needs of the future. Measures and regulations related to the increasing environmental protection sensitivity in the world will directly affect almost every area of the sector. Also, the developing technologies, increasing customer demand and intense competition; it will make the recently introduced Industry 4.0 implementation inevitable.

Abstract:
Bu çalışma, Türkiye GSM piyasasının Yarışılabilir Piyasalar Modeline uygunluğunun test edilmesi amacıyla hazırlanmıştır. Piyasanın, modele uygunluğunun test edilebilmesi amacıyla öncelikle piyasadaki firmaların ayrı ayrı kârları incelenmiş, sonrasında piyanın genel karlılığı analiz edilmiştir. 2008 – 2018 yılları arasını kapsayan analiz sonucunda piyasada aşırı karın mevcut olduğu görülmüştür. Aşırı kâra rağmen, analiz dönemi boyunca Türkiye GSM piyasasına herhangi bir firmanın giriş yapmaması, çalışmanın yönünü piyasaya giriş engellerini ve batık maliyetleri incelemeye yöneltmiştir. Spektrumun kıt bir kaynak olması, piyasada faaliyet gösterecek firma sayısını kısıtlamaktadır. Ayrıca, spektrum tahsisi için gerekli olan lisanslama maliyetleri, batık maliyet özelliği taşımaktadır. Piyasaya özgü bu iki unsur, Yarışılabilir Piyasalar Modelinin temel varsayımlarına uymamaktadır. Sonuç olarak, piyasanın daha etkin çalışabilmesi için sanal mobil şebeke operatörlerinin piyasaya entegre edilmesi önerilmiştir. | This study has been prepared in order to test the suitability of the GSM Market in Turkey to Contestable Market model. In order to test the suitability of the market to the model, firstly, the profits of the firms in the market were examined and then the overall profitability of the market was analyzed. As a result of the analysis covering the period between 2008 and 2018, it was observed that there was excessive profit in the market. Despite the excessive profit, no firms enter to the market directed the study to examine entry barriers and the sunk costs. The fact that the spectrum is a scarce resource restricts the number of firms to operate in the market. In addition, the licensing costs required for the spectrum allocation include the sunk costs. These two market-specific elements do not comply with the basic assumptions of the Contestable Market Model. As a result, it is proposed to integrate the virtual mobile network operators into the market for the market to work more effectively.

Abstract:
: Çok boyutlu bir optimizasyon problemi olan rotalama ve yerleştirme, belirli bir araç-rota matrisi üzerinden yerleşkeleri önceden belirlenmiş olan tesislerden hangilerinin ulaşım ve üretim maliyeti toplamını minimize etmek için açılıp açılmayacağı ve aynı anda açılanlar arasında hangi rotaların kullanılacağına dair geometri problemini gündeme getirir. Bu probleme Daskin ve Perl’in modeli üzerine kurulu bir denklemler seti ile heuristic bir çözüm yöntemi olan Parçacık Sürü Algoritması (PSO) ile çözüm aranmıştır. Çalışmanın orijinalliğini aldığı ve üzerine kurulu olduğu birincil köşe taşı, yerleştirme ve rotalama problemini cebirsel ve deterministik mecrada ele almak ve buna dair kurguyu vermektir. | As a multidimensional puzzle, the location and routing problem analyzes the geometric problem about which plants should be opened and which routes should be employed between the opened plants in the framework which includes a matrix of specific possible vehicle-routes and possible plants with specific locations. In this context and equation set based on Dashkin and Perl’s Model and the Particle Swarm Optimization Algoritm (PSO), which is a heuristic solution manner, have been employed in the study. The major cornerstone of this article which the study is based on is the purpose to manage the routing and location problem in the algebraic-deterministic context and to give the basic logical mind map about it.
