Racionalidade substantiva no processo decisório: um estudo em instituições que lidam com o tratamento oncológico infantojuvenil na cidade de Natal-RN

The present study regards an applied social research (qualitative) performed in two institutions which lead children s cancer treatment in Natal, Rio Grande do Norte. The main goal of this study is, as of a literature review at works which characterizes the first generations of study about substantive rationality, to detect Decision Making process related aspects that may serve as a basis to elaborate analysis categories from decision making process, aggregating them into a new study that may provide an advance to the theme in administrative science. The academic works based on the analysis model created by Mauricio Serva served as a basis to deep research into such theme, which verifies the predominant rationality in eleven administrative internal processes in productive organizations. This dissertation intends to go beyond the identification of the predominant rationality by elaborating new categories of analysis, and making possible the continuity of the subject in administrative science. Based on Guerreiro Ramos s work, which sees a kind of ideal organization, as known as isonomies, this study still calls upon Karl Polanyi s thoughts, which with the objective of comprehending the independent economic phenomenon of the value that allows considering non-market economies, find that the economy of the men is submerged in his social relations; it also rescues the studies from Max Weber who investigates the meaning of social action to better understand the rationality, and refers to the study of Jürgen Habermas, who proposes a broader conception about rationality, within the theory of communicative action. As a result of this theme s review, seven analysis categories of the decision making process have been formulated. They were applied in the institutions that had been chosen and helped to detect the type of predominant rationality in the categories of the decision making process. The results confirm that, although the decisions making process involves rational elements, such as information, identification of alternatives, there are also specific values of each individual with his experience and view oh the world, permeated not only by instrumental rationality, but also by substantive rationality. The study has verified that two similar institutions may show different types of rationality in the decision making process, when decision factors may tend to instrumental rationality, according to administration classic way, as well as they may emerge from substantive rationality, thus contributing to the process of emancipation of the human being in his sphere of work

Utilización de columnas verticales de filtración de manta y arena como pre-tratamiento de un sistema de filtración lenta

Slow sand filtration is an efficient water treatment technique used for treating surface water with relatively low levels of contamination. Despite the slow sand filtration at pathogen, algae and cyanobacteria removal efficiency, it has some restrictions in relation to the required area for slow filters, and the cleaning activities for the filters and the stone pre-filters when used in the treatment. This research evaluated during 120 days the use of non woven & sand pre-filtration columns as part of a slow filtration process for the apparent color, turbidity, algae, cyanobacteria, phytoflagellates and diatomaceous. The columns shown an efficient removal of the monitored parameters and demonstrated as a vantage their faster and easier cleaning process and less awkward than the required to the stone pre-filters. The turbidity removal efficiency increased progressively during the experiment, especially after the first 35 days of the start; the apparent color removal by the pre-filtration columns was of 85%, and working together with the polishing of activated carbon columns was up to 95; the diatomaceous, phytoflagellates, algae and cyanobacteria removal by the columns achieve a weekly average of 95%, its recommended to use filtration rates lower to 1,5m(3)/m(2)/d.

Influencia del tratamiento térmico en la cristalización y rugosidad de películas delgadas de LiNbO3 depositadas por el método Spin Coating

Lithium niobate (LiNbO3) thin films with 1/1 stoichiometry were prepared by a spin-coating from polymeric precursor method. The films deposited on silicon (100) substrates, were thermally treated from 400° to 600°C for 3 hours in order to study the influence of thermal treatment on the crystallinity, microstructure, grain size and roughness. X-ray diffraction (XRD) results showed that LiNbO3 phase crystallizes at low temperature (400°C). It was observed by scanning electron microscopy (SEM) that it is possible to obtain dense thin films at temperatures around 500°C. The atomic force microscopy (AFM) results showed that the grain size and roughness are strongly influenced by the annealing temperature.

Prótesis radífera: Alternativa en el tratamiento de neoplasias de cabeza y cuello

Radipherpus protheses are a means of treatment for malignant tumor-carrying patients. These protheses are used in cases of brachytherapy or external actinotherapy by contact and allow treating them with high radiation doses that are quickly released from the areas next to tumor, so that the radiations be restricted to the affected region, without the emissions damaging or destroying the soft tissues. Based on these considerations, the present paper was aimed at making literature review on the use of radipherous protheses for the treatment of head and neck neoplasias. © 2006 1995, Editorial Ciencias médicas.

Evaluación del conocimiento de los cirujanos dentistas brasileños sobre aspectos bioéticos en el tratamiento odontológico

Professional-patient relationship and its importance for a good performance and success of the dental treatment must be reflected upon by means of their bioethical aspects. Our study aimed at evaluating dentist-surgeons' knowledge (n=163) in conducting specialization courses at São Paulo State University-UNESP, on these aspects. Out of the people surveyed, 88.1% mentioned that a decision for the treatment should be made by mutual agreement between professionals and patients, however, 26.4% report that patients' or their legal representative's participation in decision-making can cause negative interference. Professionals' acting when patients choose a less suitable treatment, 95.6% try to convince patients that it is not the best choice and persuade them for a better one by keeping the paternalistic model. It was noticed that 20.3% did not know how to relate the importance of professional-patient interaction as regards the dental treatment. It was therefore concluded that many dentist-surgeons are not taking these bioethical aspects into account in clinical practice.

El tratamiento fisioterapéutico ¿es efectivo en el mantenimiento físico y en la reducción del declive cognitivo de las demencias?

Introduction. Dementia is a chronic and neurodegenerative disease responsible for a progressive decline of cognition and physical capacity. Objective: To verify the effectiviness of three months of physiotherapy intervention on cognitive functions and balance of institutionilized elderly people with dementia. Patients and methods. This study has comprised thirty subjects, divided in two groups: EG (experimental group) and CG (control group). EG was composed by 15 participants with mean age of 71,6 ± 8,5 years and scholarity of 4,7 ± 4,2 years. CG was formed by 15 subjects with mean age of 78,5 ± 7,6 years and scholarity of 2,2 ± 1,8 years. The sample was evaluated by means of the following instruments: Mini-Mental State Examination, Semantic Verbal Fluency test, Clock Drawing test, Berg Balance Scale and Timed Get Up and Go test. The statistical procedures were done by means of Multivariate Analisis of Variance (MANOVA), with significance of 5 % (p < 0,05). Results. The results has shown a heterogeneity of both groups related to age (F = 0,2, p < 0,05) and scholarity (F = 2,6, p < 0,05). MANOVA pointed beneficts of physiotherapy on balance (F = 7,3, p < 0,01) but not on cognitive functions (F = 0,3, p > 0,05). Conclusions. Three months of physiotherapy were effective to improuve physical capacity of institucionilized elderly people with dementia. Neverthless, it was not able to minimize cognitive decline commonly seen on dementia. The question if a prolonged intervention could propitiate cognitive beneficts remains, specially in a more homogeneous groups.

Percepción del cirujano-dentista respecto del uso del consentimiento informado en el tratamiento odontológico

The objective of this study was to evaluate: the profile of the surgeon-dentist that undergoes a course in specialization at the Odontology Faculty of Aracatuba/UNESP, Brazil; if they requested informed consent from the patient and/or their legal representative before the realization of procedures, and if the treatment was decided upon with the patient. It was elaborated, validated and applied in questionnaire form, and the data obtained was analyzed by the program EPI-INFO 3.3 The conclusion was, given that surgeon-dentists still do not obtain any type of document before beginning treatment, a large percentage of them are totally vulnerable if submitted to ethical or legal prosecution and that it is necessary to be aware of this aspect.

Aplicabilidad del proceso de nitritación/desnitritación en el tratamiento de lixiviado de relleno sanitario

The biological nitritation/denitritation process in the removal of organic matter and nitrogen in a landfill leachate was studied, using an activated sludge sequencing batch reactor. Treatment cycles were formed by an anoxic and an aerobic phases, in which the conditions for oxidation of the influent N load and the prevalence of nitrite concentration at the end of aerobic treatment cycles were determined, as well as the use of organic matter present in the leachate as a carbon source for denitrifying organisms in the anoxic stage. The removal efficiencies of N-NO 2-at the end of the anoxic process (48h) ranged between 14 and 30%, indicating low availability of biodegradable organic matter in the leachate. As for the accumulation of N-NO 2-at the end of the aerobic phase (48h) of treatment cycles, imbalances were not observed, while 100% removal efficiencies of N and specific nitritation rates from 0.095 to 0.158kgN-NH 3/kgSSV per day were recorded, demonstrating the applicability of simplified nitrification in the treatment of effluents with low C/N ratios.
