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...
در این پژوهش مسأله مقدار اقتصادی تولید در حالت چندمحصولی با ساختار سفارشات گسسته به صورت دو هدفه مورد بررسی قرار گرفته است. هدف اول در این تحقیق کمینه کردن هزینه کل از منظر خریدار و فروشنده و هدف دوم تعیین حداقل حجم مناسب انبار می باشد. این مسأله در حالتی که محدودیت سرمایه وجود دارد مدنظر قرار گرفته است و روشی مناسب برای تعیین مقدار سفارش و حجم انبار در شرکت هائی که از خدمات پیمانکاران برای تأم...
یکپارچه سازی مدیریت تولید، توزیع و موجودی یکی از چالش های محیط رقابتی امروز است. مدل مقدار تولید اقتصادی (epq) در تعیین اندازه انباشته تولید بهینه با حداقل سازی مجموع هزینه های تولید- موجودی به بنگاه ها و کارخانه ها کمک می کند. در حالی که مدل مقدار تولید اقتصادی کلاسیک صریحاً فرض می کند که اقلام تولید شده با کیفیت عالی هستند، در سیستم های تولیدی دنیای واقعی به دلیل زوال فرایند یا سایر فاکتورها ت...
This paper presents a simple algebraic approach for deriving the optimal lot size for economic production quantity (EPQ) model with rework process. Conventional methods for solving lot size problems are by using differential calculus on the long-run average production-inventory cost function with the need to prove optimality first. A few recent articles proposed the algebraic approach to the so...
Ovarian cancer is the deadliest gynecological malignancy in women, and fifth leading cause of death. Despite advances made in chemotherapy and surgery, the average time of clinical remission is approximately 2 years and the 5-year survival rate is 45%. Thus, there is an urgent need for the development of a novel therapeutic approach to ovarian cancer treatment. We investigated the effect of a s...
Objective: To explore the effect of cluster nursing mode combined with blood pressure regulation on surgical tolerance patients esophageal cancer and hypertension. Methods: The clinical data 86 hypertension treated in our hospital (February 2016–February 2017) were retrospectively analyzed. randomly split into research group reference group, 43 cases each group. received routine nursing, while ...
An EPQ model for the co-operative supply chain under the conditions of permissible delay in payments is developed in this work, in order to compare the co-operative supply chain with noncooperative supply chain; we also propose another EPQ model for the non-cooperative supply chain under the same conditions. In addition, we provide an efficient algorithm to obtain the optimal solution, and the ...
In two studies, we used the Ethics Position Questionnaire (EPQ) to investigate the relationship between individual differences in moral philosophy, involvement in the animal rights movement, and attitudes toward the treatment of animals. In the first, 600 animal rights activists attending a national demonstration and 266 nonactivist college students were given the EPQ. Analysis of the returns...
