Therefore we say that history if dedicates to study today something that is not in the gift, but is represented and tematizado in the document. History wants to know where they are the roots of the acts and behaviors that today we reveal. How and where circumstances they had been produced? How and where circumstances we become in them what we are? Periodizao One of the serious problems to study history is the dates. Much people, still think that the dates are the center of history. But not. The dates are only instruments for the localization of the facts; are created conventions to determine the indeterminate one, the time. What it matters for history is the fact. The more specifically interpretation that if can make of the fact.
Of this form, for not arresting in them to the dates and nor losing in them in the time, us we use as limiting of time spaces. We stipulate the division of secular spaces that we call of dates. To study history we choose circumscribed facts the stipulated spaces of time and we confer them some meaning. Of the point of view of history, we look for to adjust facts and dates, looking for its meaning and its localization in the time stipulated. Of this form, when we intend to locate a fact we can look using it a Line of the Time that is a form, also stipulated, for the visualization of a succession of events. To make this we place in a traced line a succession of dates related to the facts in question. This procedure helps to visualize something intangible as time. In the same way that in relation to the dates and the historical facts, here also we cannot forgetting in them that we are using a didactic resource. A resource that can help in the agreement of the concepts of passed and present, beyond in the distance that it separates in them of the studied facts.
' ' We call ' ' ente' ' many things and in diverse directions. Being is everything of that we speak, everything of that we understand, with that we hold in them of this or that way, being is also what and as we ourselves we are. To be is in what it is and as it is, in the reality, in the being simply given (Vorhandenheit), in the text and resource, the value and validity, the presence, ' ' h' ' ' '. (HEIDEGGER. 2004, P.32) In this manner the being is what we give to meanings it, a being it to be is something that if he distinguishes from excessively for the fact of the being understanding and giving meant to the world where if he inserts. The being is dismissed of world for needing significao and sensible that is given to it by the being, it he only exists for the being.
Carrying this idea to what he calls yourself of alienation he is clearly that the alienation is not in the being more receives significao for the being, to have meant is necessary that he understands it to the being in ' ' daily pay-sena' '. ' ' The presence is not only one being who occurs beings among others. In contrast, from the ntico point of view, it if it distinguishes I privilege for it of, in its being, that is, being, to be in game its proper one to be. But also it belongs to this constitution of being of the presence the characteristic of, in its to be, that is, being, to establish a relation of being with its proper one to be. This means, explicit and in some way, that the presence if understands in its being, that is, being. He is proper of this being who its being if opens it and manisfeste with and by means of its proper one being, that is, being.
The agrotxicos are substantiate chemical used in excess have asked for to farming contaminating the plants, the ground and the underground reserves of water, and the destruction of the ciliar bush it facilitates the draining of the water of the rain of these fields contaminated for the riverbeds. 3. Contamination of waters for agrotxicos agriculture in our country has one strong dependence of the use of agrotxicos, in which these have the purpose to control harmful plagues, illnesses and plants, guaranteeing raised platforms more of productivity and, consequently, greater economic return of the agricultural activity. However, the agrotxicos can highly be toxic to the diverse organisms not-target, including the human beings, mainly when these reach the freticos springs of the rivers and sheets, therefore of this form they had arrived at the contact with the man of faster and quiet form. Studies show that the agrotxicos applied directly in the plants or the ground have as final destination the ground, being washed of leves through the action of the rain or the water of irrigation, the agrotxicos had arrived at the ground, infiltrating until the layers deepest reaching the fretico sheet. Being this type of transport of the agrotxicos called of leaching.
Another important type of transport occurs when this occurs together in the surface of the ground with the water of torrents, being called of superficial draining. For occurring of very easy form the transport of these agrotxicos, such product already became 2 bigger cause of contamination of the water in the country. No matter how hard the water is one of the resources with bigger availability in the world, a great necessity exists to guarantee its quality for the current and future generations. Unhappyly, agriculture can have negative influence in the quality of the hdricos resources. This negative influence occurs, mainly, due to extreme use of the agrotxicos and without the adjusted cares, that is, in the reality the agriculturists many times do not possess no information of the cares of as to use these products.
The group had beginning with six participants locking in itself with five; the meetings had been carried through inside of the proper space of the institution, the participation were placed as voluntary, being that the participants who remained its schedule after gained overtime. In the first meeting a questionnaire was applied to know the name, escolaridade and the complaint that they brought; after that clarification on the contract was made, in this contract contained some rules as: to always arrive in the defined schedule, not to have more than three lacks without justification, to keep the secrecy on the boarded subjects and witnessed events of the meeting. Meeting had been carried through sixteen where if it worked the contents: self-knowledge, interpersonal relationship, interpersonal communication, leadership, responsibility, autonomy, adaptability; with the use of the dynamic theory of the transacional analysis and of group. During each meeting the process of development of the group was observed, having been possible to evaluate some reactions of the participants. RESULTED the initial meeting they had had as objective the comment of the expectations of the group regarding the work that would be carried through, presentation of to be worked proposal, I tie to establish it with the participants. The group if showed distant in the first meeting, did not interact between them and with the trainees, they only collaborated answering some questions and participating of the activities of dynamics, that would not be possible the accomplishment without the participation of the group, with little enthusiasm.
In elapsing of the meeting on activities to the self-knowledge had been worked, displaying the theory of the Transacional Analysis, this activity if it extended for other meeting. To each meeting if a group dynamics worked, of the autoconfiana was one of the most used. To the end of meeting the participants had changed feedback ones stop with the others, had recognized the fact of the reliable lack in them and the team of trainees.
