Identification and prioritization the factors affecting the insurance industry customer preferences using KANO and AHP model (case study:the city of Kashan(

It is noticed that the environmental changes in world market, impress the insurance companies, accepting new models for their business, as it is important to utilize the customers ideas for services, especially that the customers are affected by the environmental changes. The satisfied customers act for developing the insurance culture as, applying effective strategy, increasing the customer services and attracting the customers. In modern variable environment, it is necessary that the companies adopt themselves with variations, for continuing to survive life. Creating an appropriate structure is one of the main components and integrated features of today's societies and in the present competitive world, successful companies are those that of a step above theirs competitors. In this paper, it is tried to identificate the effective indicators in customer preferences using KANO model and finally prioritized using AHP model

Hirschsprung′s disease diagnosis: Comparison of immunohistochemical, hematoxilin and eosin staining

Background : The diagnosis of Hirschsprung′s disease (HD) is based on the absence of ganglion cells. In hemotoxilin and eosin (H and E) as well as acetylcholine esterase staining there are limitations in the diagnosis of immature ganglion cells in neonates. Methods : In this prospective study, 54 biopsies taken from suspected HD patients (five mucosal specimens and 49 full thickness specimens) were studied. In the laboratory, after preparing sections of paraffin embedded tissues, H and E staining slides were compared with immunohistochemical (IHC) staining including: S100, NSE, CD117, CD56, Cathepsin D, Vimentin, BCL2, GFAP, Synaptophysin and chromogranin. Results : The study revealed 30 negative (absence of ganglion cells) cases (55.5%), 17 positive cases (31.04%) and seven suspected cases (12.9%) of ganglion cells on the H and E staining. On IHC staining with CD56 and Cathepsin D, all of the 17 positive cases detected through H and E, were confirmed for having ganglion cells and out of 30 cases reported negative on H and E staining, 28(93.3%) were reported negative and two (6.7%) positive by IHC staining. Of the seven suspected cases H and E staining), IHC staining detectedganglion cells only in five slides; two remained negative. Conclusions : IHC staining using CD56 and Cathepsin D improved the accuracy of diagnosis in HD when used in addition to H and E staining technique, especially for negative or suspicious slides
