Retrieval and Analysis of Meat Radicidation Data by Both Databases of JICST and MEDLINE Files

Abstract

Information System (JOIS), technical problems on retrieval for users as well as on preparing relevant documents for database producers were studied with a case study concerning the research subject of meat radicidation. Referring to the results of surveys on pathogens in meats, the following six groups of bacteria were selected as an object organism to be studied: Salmonella sp., Campylobacter sp.: Yersinia sp., Listeria sp., Shigella sp. and Staphylococcus aureus. As the results of indexing, changes during 15years from 1975 to 1989 of documents concerned, relationship between retrieval formula employed and useful documents found and the conclusive data on radiosensitivities of these six bacteria and recommended radiation doses for meat radicidation were indicated. Some examples of documents were analyzed for improvement of database production and utilization. It was noted that the abstracts in databases play an important role in utilization of databases, and the use of different types of databases may provide the complementary effect on retrieval.
