OBJECTIVE To evaluate the personality and psychosocial status of adult malocclusion patients through the Eysenck Personality Questionnaire (EPQ) and the Symptom Checklist 90 (SCL-90). METHODS The EPQ and the SCL-90 were administered to 348 adult respondents with Angle's Class I, II, III malocclusion and normal occlusion. Personality and psychosocial traits were analyzed and compared among the...

 Normally, the real-world inventory control problems are imprecisely defined and human interventions are often required to solve these decision-making problems. In this paper, a realistic inventory model with imprecise inventory costs have been formulated for deteriorating items under trade credit policy within the economic production quantity (EPQ) framework. We assume that the supplier would...

OBJECTIVE To investigate the long-term outcome and changes of the personality and psychopathological profile of opiate addicts after bilateral stereotactic nucleus accumbens (NAc) ablative surgery. METHODS 60 patients were followed up for 5 years and abstinent status and adverse events were evaluated. NAc lesion volumes and locations were obtained by postoperative MRI scans. The Chinese versi...

Huang [Mathematical Problems in Engineering, 2006, ID 79028, 1-5] studied the effect of service level constraint on the economic production quantity (EPQ) model with random defective rate. He offered an algebraic approach to replace his differential calculus skill to find the optimal solution under the expected annual cost minimized. In this article, we want to use an easy and simple arithmetic...

A real economic growth only comes from increasing quality and quantity of the factors of production. Most production systems produce items which are of imperfect quality. In a production/inventory situation items which are received or produced are not of perfect quality. Thus the presence of defects which is inevitable in a produced/ordered lot is sorted out by the process of screening. Handlin...

In this paper, we study an economic production quantity (EPQ) problem in which an item is produced by a single machine. We assume that the machine may fail in an exponential random time. The repair time is an exponential random variable. It is possible to satisfy the demand from an outside supplier when the machine is failed. The objective is to determine the production and order quantities in ...

This paper deals with an economic production quantity (EPQ)model for deteriorating items with price and advertisement dependent demand. We have considered three types of continuous probabilistic deterioration functions to determine the total inventory cost. Here, the rate of replenishment is considered to be a variable and the generalized unit production cost function is formulated by incorpora...

The main purpose of this paper is to investigate the retailer’s optimal cycle time and optimal payment time under the supplier’s cash discount and trade credit policy within the economic production quantity (EPQ) framework. In this paper, we assume that the retailer will provide a full trade credit to his/her good credit customers and request his/her bad credit customers pay for the items as so...
