The development of a standardized food model is presented. Based on the findings of a systematic literature search an elastic food model was created with the aim of standardizing size and elastic properties. Three different eatable jellied products were chosen, created by a changing of the amount of gelatin (260 Blooms) related to the total mass of the standard jellied food. The different hardness were classified in soft, medium and hard, flavored identically, but stained with different colors: soft-green, medium-yellow, hard-red. A cylindrical form was chosen with a height of 1 cm and a diameter of 2 cm. A standard protocol for analyzing chewing patterns in men was created. The condylographic data off several patients are described in details to demonstrate the possible clinical implementation. The newly developed standard food model (SFM) showed the capability to serve in experimental settings to analyze human mastication, although only a few patients have been examined. In addition, strength and size of the newly developed SFM load the masticatory system in an extent;it should be possible to disclose subclinical symptoms of patients within a short time of examination. The diagnostic procedure of temporo-mandibular disorder (TMD) should be endorsed by this new method. The condylographic data created by a standardized protocol should have the ability to enhance the clinical functional analysis of patients previous to restorative dental procedures.展开更多

Based on the analysis of economic rationality and system drive for food enterprises to implement ISO9000 Series Standards, we determine the economic factors and institutional factors influencing enterprises' implementation of ISO9000 Series Standards, and establish corresponding indicator system. According to survey data on 86 enterprises in Sichuan Province, we draw the following conclusion using the Logit model: enterprise age and enterprise size in economic factors, government's food safety control intensity, consumers, public and media pressure, awareness of senior managers, strategic orientation of quality safety, employees' average educational level in institutional factors, have a significant effect on enterprises' implementation of ISO9000 Series Standards. According to research results, we put forth some recommendations for promoting food enterprises to implement ISO9000 Series Standards.展开更多
