title: Theoretical Optimal Trajectories for Reducing the Environmental Impact of Commercial Aircraft Operations

description: ABSTRACT: This work describes initial results obtained from an ongoing research involving the development of optimization algorithms which are capable of performing multi-disciplinary aircraft trajectory optimization processes. A short description of both the rationale behind the initial selection of a suitable optimization technique and the status of the optimization algorithms is firstly presented. The optimization algorithms developed are subsequently utilized to analyze different case studies involving one or more flight phases present in actual aircraft flight profiles. Several optimization processes focusing on the minimization of total flight time, fuel burned and oxides of nitrogen (NOx) emissions are carried out and their results are presented and discussed. When compared with others obtained using commercially available optimizers, results of these optimization processes show satisfactory level of accuracy (average discrepancies ~2%). It is expected that these optimization algorithms can be utilized in future to efficiently compute realistic, optimal and 'greener' aircraft trajectories, thereby minimizing the environmental impact of commercial aircraft operations.

title: Mild cognitive impairment (MCI) and dementia in a sample of adults in the city of Bogotá

description: ABSTRACT The low prevalence of dementia described in communities is likely due to the low sensitivity of screening tests and an absence of evaluation by specialists. OBJECTIVE: To estimate the prevalence of mild cognitive impairment (MCI) and dementia in adults older than 50 years. METHODS: A two-phase, cross-sectional study was conducted by specialists to evaluate cognition and associated demographic risk factors in 1,235 independent community-dwelling adults from Bogotá. In Phase I, screening was performed using the MMSE and MoCA tests. In Phase II, after application of a comprehensive neuropsychological battery with neurologic and psychiatric evaluations, a cognitive diagnosis was established by consensus. RESULTS: The prevalence found for MCI was 34% and for dementia was 23%. MCI was associated with incomplete high school, OR=1.74 (95%CI=1.23-2.45), and with an age of 70-79 years, OR=1.93 (95%CI=1.47-2.53). A total of 73% of MCI cases were amnestic. Dementia was associated with incomplete primary education, OR=8.98 (95%CI=5.56-14.54), complete primary education, OR=6.23 (95%CI=3.70-10.47), and age older than eighty years, OR=3.49 (95%CI=2.23-5.44). CONCLUSION: The prevalence of dementia found was greater than the rates reported in previous studies. Low educational level was the main risk factor for cognitive impairment and should be considered in strategic planning for the local health system.

title: Pregnant women's oral health: knowledge, practices and their relationship with periodontal disease

description: ABSTRACT Objective To evaluate pregnant women's knowledge and perception of oral practices as well as their relationship with periodontal disease. Methods The project was developed in 27 units of the Family Health Strategy in the city of Picos, State of Piauí, Brazil, whose service prioritized providing the first dental appointment for pregnant women. A questionnaire was applied to 302 pregnant women, and a calibrated examiner (Kappa=0.96) performed the intraoral exam (CPI). Results the disease was present in 90.7% of them, although 96.4% had been to the dentist once, the majority have not seen a dentist during pregnancy, either because they feared the treatment would harm the baby, or lack of perceiving the need for doing so. Among those that had seen a dentist, did so because of pain or due to routine dental appointments. (19.9%). The belief that pregnancy could cause oral problems was mentioned by 39.7%, however, the majority (98.3%) stated they had received no guidance in this period, a fact which was shown to be associated with periodontal disease (p=0.0003). Conclusion It was concluded that there had been disease prevalence in the group, becoming persistent throughout pregnancy and also that the women presented many oral health care doubts during their gestational period.

title: Oral health care for people with visual impairment

description: Abstract Background approximately 285 million people are visually impaired, oral health care to people with visual impairment differs due to the conditions’ limitations, which may affect the individuals’ dental care. Objective to evaluate the access and satisfaction of people with visual impairment to oral health services and their relationship with the economic condition. Method this is a cross-sectional quantitative study involving people with visual impairment of an Institute for the Blind. A semi-structured questionnaire was used to obtain data, where variables were: access to oral health services, satisfaction and socioeconomic status. After the data collection, the data were tabulated by Epi Info 7.2. Results of the total number of respondents (n = 72), 65.28% were males, with a mean age of 34.6 years. Regarding access to oral health services, 56.9% of the interviewees reported that the last visit to the dentist was less than one year, and the majority (84.3%) classified the treatment of the last consultation with good or very good. Access to oral health services occurred in both the public and private systems, regardless of the economic class of the respondent (p = 0.174). Conclusion in spite of the positive results, access and dental care for people with visual impairment requires the creation and expansion of inclusion and accessibility policies.

title: The lied chidhood and the profaned future: the narratives by Valêncio Xavier

description: The works of Valêncio Xavier are characterized, in formal terms, by using various types of images (drawings, photographs, newspaper articles, flip books), elements that make hybrid narratives. Such artifacts are arranged in order to compose an album in the novel Minha mãe morrendo e o menino mentido and an obituary in Meu 7º dia: uma novella rébus. From a lied childhood to a desecrated funeral, Valêncio Xavier lights and reworks childhood memories and designs and mocks the inevitable future. Thus, this study aims to discuss structural and thematic attributes of the works of this Brazilian author to reflect on these narrative albums that create the past and the future.

title: The prescription of psychotropic medication and the knowledge of brazilian regulatory legislation by dental surgeons

description: Abstract Background The use of psychotropics by dental surgeons is permitted by law in Brazil for specific clinical cases. There are few studies on its use in dentistry. Objective This study investigated the prescription of psychotropics drugs by dentists enrolled in the Regional Council of Minas Gerais and their knowledge about regulatory ordinance 344/1998. Method An electronic questionnaire with 13 questions addressing the prescription of psychotropic drugs was sent to 15250 dental surgeons and 969 questionnaires were answered. It was considered the time of graduation, type of undergraduate institution, type of postgraduate course, more frequent prescribed medication, knowledge about ordinance 344/1998 and more frequent public that receives the prescription. Results Two hundred and fifty-seven professionals prescribe psychotropic drugs and 223 know the law, and a worrying percentage of professionals who prescribe these drugs does not know the content of the Ordinance 344/1998. Opioid analgesics are the most prescribed psychotropic medications. Specialists are the ones who prescribe psychotropic drugs (p=0.015) and those professionals who prescribe anxiolytics know the legislation more frequently (p=0.003). The maxillofacial surgeons (p=0.02) and experts in disorders of the temporomandibular jaw joint (0.03) are the ones who know the law and prescribe psychotropic medication. Strong pain and fear are the two main reasons for prescribing psychotropic drugs. Conclusion Being a specialist and knowing the ordinance 344/1998 are factors associated with the prescription of psychotropic medications among dentists.

title: PEDOGENESIS ON COASTAL TABLELANDS AREA WITH LOW RANGE ALTIMETRY IN PARAÍBA STATE

description: ABSTRACT Small variations of relief may change drainage and runoff and hence promote the formation of sandy surface horizons and hardened subsurface horizons (fragipans and/or duripans) in Coastal Tablelands soils. This study aimed to investigate the pedogenesis on Coastal Tablelands area with low range altimetry in Paraíba state; secondly, we also sought to contribute to the improvement of the Brazilian Soil Classification System (BSCS). Four soil profiles ware described and collected to be submitted to routine physical and chemical analysis, determination of Fe, Al and Si extracted by sulfuric acid digestion, sodium citrate-bicarbonate-dithionite and acid ammonium oxalate, sodium pyrophosphate, and mineralogical analysis in the sand and clay fractions by X-ray diffractometry. Optical density of the oxalate extract (ODOE) was also determined; the results were statistically evaluated using the R software. Microrelief variations conditioning differentiated water flows, along with the sandy texture of the surface horizons (A and E) and the lower coarse sand/fine sand ratio in the subsurface horizon, seem to promote clay accumulation in depth in the Spodosols developed on Coastal Tablelands environments. For this soils, the argilluvic (argissólico) character at the subgroup level of the BSCS should be incorporated. In addition, Al amorphous mineral phases and/or poorly crystalline play an important role in the formation of strongly cemented horizons (duripans) of the Spodosols, as also reported by other authors. Finally, the ODOE showed to be an efficient indicator of soils under podzolization process, being possible its use as a taxonomic criterion for classification of Spodosols by the BSCS.

title: Environmental sustainability in hotels, theoretical and methodological contribution

description: Abstract The environmental sustainability is a multidisciplinary subject and its scope has attracted the attention of researchers from various fields of knowledge. In this perspective, the environmental management in the hotel industry stands out for two aspects: first, the economic importance of the hotels, a key element of the tourism sector, and second, the environmental impacts generated that need to be managed. Thus, it is important to examine how this subject has been addressed by the academia. In this sense, the objective of this research, exploratory and descriptive in nature, consists of mapping the theme of sustainability management in hotels, according to the delimitations set by researchers. To accomplish this purpose, we used the Knowledge Development Process - Constructivist (ProKnow-C). At the end of the survey, 13 articles were identified, published in international journals within the framework established by the researchers. The development of the Bibliographic Portfolio (BP) has taken into account some aspects: (i) relevance and adherence to the theme of the articles; (ii) proposals and results obtained in the research; (iii) theoretical and methodological contribution of the research published in the BP items. The results show that the topic is relevant and current, and that it lacks a structured process to evaluate the environmental management, in order to support management decisions.

title: 'For them, we are not humans!’: housing, space and monitoring of racialized violences in Portugal

description: Abstract This article presents a critical analysis on a set of reports produced by national and international agencies that, in the course of the last two decades, have been monitoring racialized inequalities in access to housing. The analysis is informed by an ethnographic journey throughout a set of self-produced spaces and rehousing projects inhabited mainly by Roma populations, aiming to explore the relationship between segregation, racialization and dehumanization processes in contemporary Portugal.
