OBJECTIVE To evaluate the distribution of skin lesions, clinical features, and associated abnormalities in children with cutis marmorata telangiectatica congenita at onset and during follow-up. DESIGN Retrospective survey of the available medical data with an average follow-up of 1 year 5 months (range, 0-7 years). SETTING Pediatric Dermatology Unit (Department of Dermatovenereology) of the...

Gastric epithelial dysplasia (GED) represents a recognized precursor lesion of gastric adenocarcinoma. GED types can be classified according to its morphology and patterns of mucin expression into adenomatous (intestinal), foveolar (gastric) and hybrid (mixed) types. We examined gastroscopic specimens with GED in 35 patients (21 men and 14 women, mean age 69.6 years). Adenomatous dysplasia was ...

In this paper we review research that has been done to address cellular manufacturing under conditions of multi-period planning horizons, with demand and resource uncertainties. Most traditional cell formation procedures ignore any changes in demand over time caused by product redesign and uncertainties due to volume variation, part mix variation, and resource unreliability. However in today‟s ...

In a competitive market, semiconductor fabricator must face an environment with multi-product types, multi-priority orders and demand changes in time. Since semiconductor fabrication has a very complicated production process, the above-stated characteristics make the production planning even more difficult. This paper applies data envelopment analysis (DEA) to find a set of product family mix t...

BACKGROUND Surveys of the experience of cancer patients are increasingly being introduced in different countries and used in cancer epidemiology research. Sampling processes, post-sampling mortality and survey non-response can influence the representativeness of cancer patient surveys. METHODS We examined predictors of post-sampling mortality and non-response among patients initially included...

Introduction: Quality of services extremely depends on how personnel have contact and interaction with the clients. Moreover, the personnel’s attitudes and their behaviors with the clients significantly affect clients’ perception of quality of services and consequently influence their satisfaction as well as their absorption to the services of an institution. This study intends to investigate t...

Firms' decisions about which goods to produce are often made at a more disaggregate level than the data observed by empirical researchers. When products differ according to production technique or the way in which they enter demand, this data aggregation problem introduces a bias into standard measures of firm productivity. We develop a theoretical model of heterogeneous firms endogenously self...

OBJECTIVES To study children who had undergone stapedectomy at an age younger than 16 years to determine the causes (particularly frequency of congenital anomalies vs otosclerosis) and to analyze the functional results over the short-term, 1-year, and long-term postsurgery time course. DESIGN Ten-year retrospective study covering 1998 to 2008. SETTING Pediatric tertiary care centers. PATI...

BACKGROUND Pincer nail is a nail deformity characterized by transverse overcurvature of the nail plate. Pincer nail can affect a patient's quality of life due to its chronic, recurrent course; however, there have been no clinical studies on the pincer nail condition in Korean patients. OBJECTIVE The purpose of this study was to characterize the clinical findings and treatment of pincer nail. ...

This paper presents a series of experiments that were conducted to investigate in the instationary behavior of a wafer fab after changes in product mix. The experiments were performed using a simulation model of the front end area of an existing semiconductor fab. We observe how short-term increases in wafer starts of a product influence the cycle time and WIP of this product and of the other p...
