ABSTRACT

Statement, through SDI-Documentation and Information Service of FEUP, by an integrated search in the database in the form of Meta Search. The type of resource used was the “Database”, and the survey was conducted separately for each database. Six advanced search Databases were selected, taking into account those that are relevant to this study. We selected three groups of key words each corresponding to a set of words of the same subject/ area: Group I-Vibration in forklift driving; Group II-Nordic Questionnaire and associated symptoms; Group III-Storage and Transporting Industries. The search was performed in the “advanced search” mode, in which boolean terms/operators (“and”/“or”) were used to connect the words in a text field and between different text fields. After the first search it was recorded the number of items found. Later exclusion criteria were applied to further refine search and direct it as much as possible for relevant content to the dissertation topic and in order to have the most current information possible. Thus the following criteria in order were applied:

− Limit only “Journal Articles” or “Article Reviews”; − Refine to: Publication year higher than 2000; − Exclusion of repeated articles; − Limit only the English language; − Refine by keywords; − Refine by title; − Refine by content/abstract.
