In this study the reliability and scientificity of organoleptic evaluation for the commercial specification of Chinese medicinal materials (CMM) was investigated with Delphi method, using rhubarb as an example. The consensus panel of panelists being expert in organoleptic evaluation for CMM was cogitatively selected, with high average authority index of 0.81. The average individual repeatability of selected panelists was 85%, while the group repeatability was above 70%. It was found that the career time of the expert had significant influence on the evaluation result (P < 0.05), which suggested that practice makes repeatability. Some panelists of different career type and education background concluded different results, but no statistical significance was found. Furthermore, four predominant organoleptic parameters, shape, color, texture and section characteristics, were selected based on statistics and panelists' discussion to judge the commercial specification of rhubarb. In conclusion, we firstly demonstrated the organoleptic evaluation is an objective and repeatable approach to judge the commercial specification of CMM; and we recommend Delphi method to do validation and standardization for the conventional experiences of traditional Chinese medicine.

To construct an evaluation indicator system on food safety management capacity for food production enterprises by Delphi method, and to provide a scientific theoretical framework for food safety management capacity for food enterprises.
 Methods: A framework for the evaluation system on food safety management capabilities was established and experts in relevant fields were invited to conduct 2 rounds of expert consultation. Indicators were selected and determined based on expert opinions and statistical analysis results. The hierarchical model was constructed by the analytic hierarchy process to determine the weight coefficients of each indicator.
 Results: The positive coefficients of the two rounds of expert consultation were 84% and 100%, and the coefficient of experts' authority was 0.826. The coordination coefficients of the indicators in the first round of consultation were 0.439, 0.323 and 0.324, and they were 0.607, 0.351, and 0.368 in the second round, respectively, with statistically significant differences (P<0.001). The evaluation index system of food safety management capacity for food production enterprises was established after the two rounds of expert consultation, and the system consisted of 5 indicators for the first level, 18 indicators for the second level and 32 indicators for the third level, with corresponding weights. 
 Conclusion: The enthusiasm, authority and concordance of experts during this consultation are good, and the selected indicators are reasonable and comprehensive, which can provide a basis for the evaluation of food safety management capabilities for food enterprises.

The purposes of this study were to investigate the importance level on factors affecting the foodservice management contract perceived by the salespersons in the foodservice company. To get the data on the perceived importance level on the affecting the foodservice management contract, the questionnaires were developed by the delphi technique and modified by the pilot test. The questionnaires consisted of 4 categories and 19 items on the factors affecting the foodservice management contract and the importance level on the factors were measured by 5-likert scale. From March 12 to April 13 in 2003, the self-administrative questionnaires were mailed to the 60 salespersons. The questionnaires were responded from the 48 salespersons(respondent rate : 77 %). As a result, the salesperson' perceived importance level of 'the sales ability' was higher than those of the other categories in the private contract and the salesperson' perceived importance level of 'the evaluation of the foodservice company' was higher than those of the other categories in the competitive bid. The importance of the 'the evaluation of the foodservice company' between the private contract and the competitive bid was significantly different(p<.05), and the importance of 'the sales ability' of the competitive bid was significantly higher than that of the private contract(p<.001).

OBJECTIVETo construct and evaluate the criteria of injury based on the theoretical model that 'Injury' is the combination of 'Hurt' and 'Harm', in order to provide theoretical basis for scientific and rational research on injury in future epidemiological survey.

METHODSThe criteria of epidemiological injury was consected by analyzing documents and consulting experts, then Delphi method was used to evaluate its rationality.

RESULTSThe epidemiological definition for 'Injury'is the combination of 'Hurt' and 'Harm'. 'Hurt' means the wound in clinical medicine, while 'Harm' means the damage from the views of public health. The active coefficients of two rounds Delphi Method were both 100%. The authority coefficients of two rounds were 0.88 and 0.87, respectively. The coordination coefficients were 0.44 and 0.62 (P<0.05), respectively. After two rounds consulting, all scores of rationality for definition of 'Hurt', definition of 'Harm', 'Injury' being the combination of 'hurt' and 'harm', 'Injury' should be graded, Graded based on the 'Injured' time were above 3, and all values of CV for those index were below 0.25 except Graded based on the 'Injured' time.

CONCLUSIONThe rationality of Definition of 'Hurt', Definition of 'Harm', 'Injury' being the combination of 'hurt' and 'harm', 'Injury' should be graded and Graded based on the 'Injured' time is good. There is still a certain degree of divergence about Graded based on the 'Injured' time.

OBJECTIVETo develop dataset for basic medical information system.

METHODSAll items of basic medical information system dataset were drafted by literature review, brain storm and group discussion. A Delphi study was conducted to evaluate and adjust the candidate items; then items were finalized based on comprehensive scores.

RESULTSThe final dataset developed through two-round Delphi study contained 20 first-level items, 102 second-level items, 40 third-level items and 88 fourth-level items. The response rates were 71.79% and 92.86% in round 1 and 2, respectively. The authority coefficient was both 0.77 and the coordination coefficient of the specialists' opinion was 0.239 and 0.516, respectively.

CONCLUSIONThe dataset for basic medical information system determined from Delphi study is credible and can be used for development of related software.

OBJECTIVE: To build a physiological aging scale for healthy people.
 METHODS: We collected age-related physiologic items through literature screening and expert interview. Two rounds of Delphi were implemented. The importance, feasibility and the degree of authority for the physiological index system were graded. Using analytic hierarchy process, we determined the weight of dimensions and items.
 RESULTS: Using Delphy mothod, 17 physiological and other professional experts offered the results as follow: coefficient of expert authorities Cr was 0.86±0.03, coordination coefficients for the first and second round were 0.264(χ2=229.691, P<0.001) and 0.293(χ2=228.474，P<0.001), respectively. The consistency was good. The aging scale for healthy people included 3 dimensions, namely physical form, feeling movement and functional status. Each dimension had 8 items. The weight coefficients for the 3 dimensions were 0.54, 0.16, and 0.30, respectively. The Cronbach's α coefficient of the scale was 0.893, the reliability was 0.796, and the variance of the common factor was 58.17%.
 CONCLUSION The improved Delphi method or physiological aging scale is satisfied, which can provide reference for the evaluation of aging.
