BACKGROUND We believe that instances of neuroticism and common psychiatric disorders are higher in adults with acne vulgaris than the normal population. OBJECTIVE Instances of acne in adults have been increasing in frequency in recent years. The aim of this study was to investigate personality traits and common psychiatric conditions in patients with adult acne vulgaris. METHODS Patients wh...

The purpose of the study was to examine whether poor working conditions influenced drivers' psychological health, and to identify drivers' personality characteristics. The subjects were 208 bus drivers working in the European sector in Istanbul. Their personality characteristics, psychological symptoms and anxiety levels were investigated using the Eysenck Personality Questionnaire (EPQ), the S...

This paper investigates a production inventory model under classical EPQ framework with the assumption that customer demand during stock-out period is affected by accumulated back-orders. The backlog rate not fixed; instead, assumed to decrease proportionally existing which thereby approximated piecewise constant function. Deteriorating items are taken into consideration in this work. For bette...

Huang and Huang [International Journal of Systems Science, 39 (2008), 539-546] offered the algebraic approach to investigate the retailer’s replenishment policy under trade credit on the economic production quantity (EPQ) model. In this paper, we propose an arithmetic-geometric mean inequality method to simplify the algebraic method of completing perfect square established by Huang and Huang (2...

 Imperfect production processes lead to imperfect products and decrease the profit of a business. Improvement in the production process by increasing the investment cost will decrease the defective percentage of items. This study develops an EPQ model with investments on imperfect production processes under limited capital. An algorithm is developed to derive the replenishment and investment p...

This paper studies the optimal producer′s replenishment policy for an economic production quantity (EPQ) model with rework and breakdown taking place in backorder replenishing time. A recent published article has studied the lot-sizing problem on an imperfect quality EPQ model. However, another reliability factor random machine breakdown is inevitable in most real-life production systems. To de...
