The information retrieval process involves subjective, imprecise and vague concepts, such as "information need", "relevance", and the very concept of "information". The main information retrieval models treat these concepts accurately, represented by a single numerical value. The fuzzy logic, while operating with the uncertainty of natural phenomena in a systematic and rigorous manner, represents a promising alternative to solve some problems related to information retrieval. This paper presents the fuzzy logic and some examples of its use in information retrieval systems (IRS).

The proposal of present paper is to present a conceptual and terminological discussion relative to the terms: organizational memory, corporate memory and institutional memory that is a subject still little studied and explored in the academic area. The study is theoretical focus and the research kind is bibliographical. As research sources were utilized: books, digital libraries of theses and dissertations in the scope of the country and CAPES Journals Portal. This study is in course and is part of doctorate research "Organizational memory and the knowledge bases constitution". As the partial results, observes that the question about "memory" is studied by different areas of knowledge: Psychology, Neurosciences, History and others; the concepts about organizational memory and corporate memory are studied by Administration and Information Systems areas; the concept of institutional memory is more studied by Business Communication area focusing the company history. Beyond that, observes the use of another term, social memory, utilized by Information Science and History areas.

Information flows are responsible for the dynamics and the interaction between the various sectors of the organization and among individuals who work in it. By mapping performed in internal and external environments of the organization, it is possible to highlight the informational needs of organizational individual, since they depend on data, information and knowledge to perform their actions in the corporate environment. To meet the information needs of organizational individual need to manage the existing information flows, how it can settle and move effectively in the organizational environment. It is argued that the environments and existing information flows in an organization, subsidize the process of organizational competitive intelligence, since they are inputs for decision making and enable the planning and execution of actions in the short, medium and long term.

It was observed the metacognitive trajectory of three users from a public university library the state of Sao Paulo to identify the metacognitive strategies that were used during the process of searching for information in a online collective catalog. Its configuration was based on participants' oral reports obtained by the technique of individual verbal protocol to provide an actual configuration of the task ans a closer examination of its natural recovery of information systems. The data collection sessions were recorded, and the recorded data were transcribed and categorized into four units of analyses: 1- expertise, 2-regulation, 3-assessment of knowledge itself and 4- organization of cognitive process. The results showed that knowledge of meta-cognitive strategies affects the quality of the results obtained in the process of searching for information and interferes in the way it implements retrieval on-line catalog, a fact the emphasizes the need for studies to move forward on issues meta-cognition of users of information.

The search for more reliable security systems and information management of these systems is leading to a growing progress in new technologies investments that allow the implementation of equipment with a high level of reliability, but also have an agile and practical operation. This led people to turn increasingly looking for home automation systems, enterprise and industry for the automation and integration of their systems. The identification by radio frequency is very widespread today for ensuring both agility in handling records data, the reliability of their identification systems, which are increasingly advanced and less susceptible to fraud. Attached to this technology, the use of the database is always very important for the storage of information collected, the area where the MySQL platform is widely used. Using the open source Arduino platform for programming and manipulation of RFID module and LabVIEW software for the union of all these technologies and to develop a user-friendly interface, you can create a highly reliable access control and agility places a high turnover of people. This project aims to prove the advantages of using all these technologies working together, thus improving a flawed system effectively safety, cheaper and quicker
