A aquicultura é a atividade que mais cresce dentre os setores de produção de alimentos, porém, sua prática pode causar impactos ambientais no ambiente aquático, caso não haja um plano de monitoramento eficiente. O objetivo do presente trabalho foi avaliar o grau de trofia do ambiente utilizando o Índice de Estado Trófico (IET) em uma atividade aquícola de sistema de produção em tanques-rede no reservatório do Lajeado, Palmas, Tocantins na estação seca do ano. O monitoramento foi realizado no período de maio/2017 a agosto/2017 e envolveu a coleta de amostras para análises dos seguintes parâmetros de qualidade de água: fósforo total e clorofila-a. Paralelamente, houve a realização de coleta de dados de temperatura, turbidez, oxigênio dissolvido, condutividade, pH e sólidos totais dissolvidos. Os resultados do cálculo do Índice de Estado Trófico (IET) mostraram que a área em estudo durante os meses de maio e agosto apresentou-se predominantemente em graus eutrófico e hipereutrófico. O ponto controle também apresentou alto grau de trofia, indicando que o estado trófico do lago nas proximidades da área aquícola sofre forte influência de atividades antrópicas externas. Assim, os efeitos desta atividade a médio e longo prazo são difíceis de serem previstos, havendo a necessidade constante do monitoramento e controle da qualidade da água.Palavras-chave: aquicultura, eutrofização, impacto ambiental, poluição, tanque rede. MONITORING OF AQUACULTURE IN CONTINENTAL RESERVOIRS USING THE TROPHIC STATUS INDEX ABSTRACT:Aquaculture is the fastest growing activity among food production sectors, however, its practice can cause environmental impacts, in case if a monitoring plan is not applied. The objective of the present study was to evaluate the trophic environment status using the Trophic State Index (TSI) in an aquaculture activity in a netcage system in the Lajeado reservoir, Palmas, Tocantins during the dry season. The monitoring was carried out from May / 2017 to August / 2017 and involved the water sampling for analysis of the following water quality parameters: total phosphorus and chlorophyll-a. At the same time, data were collected on temperature, turbidity, dissolved oxygen, conductivity, pH and total dissolved solids. The Trophic State Index (TSI) results showed that the area under study during the months of May and August was predominantly under a supereutrophic condition. It indicates that the lake trophic state in the aquaculture surrounding area is strongly influenced by external anthropogenic activities. Thus, the effects of this activity in the medium and long term are difficult to predict, so it´s necessary to monitor and control the water quality.Keywords: aquaculture, eutrophication, environmental impact, pollution, net cage.

Published: April 2019

The article analyzes the peculiarities of language self-presentation of Internet users. The results of the study of nicknames as means of linguistic self-presentation of persons with eating disorders in the specialized Internet forums are presented.
The psychological analysis of users’ nicknames of sites of anorexic and overweight individuals is presented which gives an opportunity to assert that nicknames reflect the specific nutritional problem and self-administration of a person in connection with it. The predominance of the female audience of such sites is revealed and hence the greater urgency of the problem of standards of the body for women. In the process of analysis, on the basis of psycholinguistic and projective approaches, the main categories of nicknames are singled out: exo-decorative names; metaphorical, decorative and mysterious nicknames; mythical and fantasy characters; destructive, problem image; names that reflect the physical status, etc.
It has been established that nicknames as attributes of linguistic self-presentation of users of specialized forums, is a symbolic projection of the discourse of their existence and reveals the features of real or desired body parameters; dissatisfaction with weight, with your body, yourself and life in general; fixation on the issue of nutrition and weight reduction; the desire to be fenced off from reality. Differences in the linguistic self-presentation of anorexics and overweight individuals are revealed, in particular, a more positive modality of self-presentation of overweight individuals; the representation of various categories of linguistic self-presentation in these groups which allows to assert the difference in the mechanisms of psychological protection in these groups of users. The analysis of the features of nicknames as a means of linguistic self-presentation is useful both for the purpose of psychodiagnostics of people with eating disorders, as well as in the process of developing and providing them with psychological assistance.

Positive examples of forest-ungulate situations focusing on silver fir regeneration
Roe deer, chamois and red deer browse on the apical shoots of young trees, and particularly selected are those of the European silver fir. Because of this selective feeding of ungulates, the silver fir is unable to sustain its population density relative to other tree species. However, due to locally functioning forest-ungulate situations, there have been areas of improved silver fir regeneration during the last few years. In this study, twenty different sites exhibiting such improvement have been analysed. Eighteen sites were situated in thirteen different Swiss cantons, as well as one each in Germany and Austria. With the aid of interviews with experts such as local foresters, gamekeepers, hunters and representatives of the cantonal departments of hunting and forestry, the importance of sixty-six potential influencing factors on a locally improved forest-ungulate system has been investigated. Frequency analysis has shown that the density of roe deer, the availability of light and the presence of lynx are the most important of these factors. But also the density of chamois, the increased focus on a natural regeneration and the form of management have been frequently mentioned as central factors. Changes in communication between the hunting and forestry sides have been considered most often as central or important. Positive examples could be examined in all regions of Switzerland – in cantons with patent hunting and hunting districts as well as in areas with different densities and compositions of wild ungulates. It does not seem that a single influencing factor, but rather a combination of different factors was decisive for improved silver fir regeneration.

BACKGROUND: In the classical process, it was proven that ABPM data were the most significant attributes both by physician and ranking algorithms for dipper/non-dipper pattern classification as mentioned in our previous papers. To explore if any algorithm exists that would let the physician skip this diagnosis step is the main motivation of the study. OBJECTIVE: The main goal of the study is to build up a classification model that could reach a high-performance metrics by excluding ABPM data in hypertensive and non-diabetic patients. METHODS: The data used in this research have been drawn from 29 hypertensive patients without diabetes in endocrinology clinic of Marmara University in 2011. Five of 29 patient data were later removed from the dataset because of null data. RESULTS: The findings showed that dipper/non-dipper pattern can be classified by artificial neural network algorithms, the highest achieved performance metrics are accuracy 87.5%, sensitivity 71%, and specificity 94%. CONCLUSIONS: This novel method uses just two attributes: Ewing-score and HRREP. It offers a fast and low-cost solution when compared with the current diagnosis procedure. This attribute reduction method could be beneficial for different diseases using a big dataset.

Published: April 2019

In 2005, global cardiovascular diseases caused 30% of deaths in Europe, which is 46% of total deaths for all death groups. Today, according to the International Adult Diabetes Federation, 20% to 25% of the adult population in the world has Metabolic Syndrome. Turkish Statistical Institute claims that in Turkey 408782 people died of circulatory system diseases in 2016 and it is expected that numbers will dramatically increase. In 2003, total worldwide healthcare budget of Diabetes Mellitus was up to 64.9 billion International Dollars with the continuing rise in prevalence, it is expected that total costs will increase to 396 billion International Dollars by 2025. The main purpose of this study was to present a clinical decision support system that calculates Metabolic Syndrome existence and evaluate HeartScore risk level for Turkish population. The second objective was to create a detailed personal report about individual’s risk level of Metabolic Syndrome and HeartScore and give advice to him/her to reduce it. The fuzzy logic risk assessment system (FLRAS) was formed in LabVIEW graphical development platform according to International Diabetes Federation and European Heart Journal’s criteria. Mamdani type fuzzy logic sets were identified for each input variable and membership functions were assigned depending on the magnitude of the input limits. System’s performance was tested on 96 (72 females, 24 males) patient data. Results show that the proposed system was able to evaluate the Metabolic Syndrome risk with 0.9285 specificity, 0.92708 accuracy and 0.925 sensitivity.

Published: April 2019

BACKGROUND: The morbidity of breast cancer has continuously achieved a global topicality. In particular, during the last decade several ten thousand female adults in Taiwan have been confirmed as breast cancer patients. OBJECTIVE: To predict the survival rate of breast cancer patients at various (0-IV) stages and provide efficient assessment of proposed radiotherapy for patients. METHODS: The prediction algorithm proposed is based on the revised hit and target model and implies the application of Taylor series expansion to the population-based survey dataset. The proposed algorithm features a specific function comprising a single simple exponential term [Formula: see text] to imply the fundamental degradation of patient’s health multiplied by an additional term [Formula: see text], which specifies the recovery effect of a particular therapy. RESULTS: Its calculated values for breast cancer patients who undergone radiotherapy at different stages 0-IV were {0.0029, 0.0066, 0.0178, 0.0475, 0.1785} yr[Formula: see text], respectively, while those for corresponding groups of patients with no radiotherapy were assessed as {0.0072, 0.0137, 0.0264, 0.0913, 0.2425} yr[Formula: see text]. CONCLUSIONS: The revised algorithm successfully interpreted the breast cancer patients’ survival rate at stages 0-IV and evaluated the necessity of radiotherapy for patients at various stages as well.

Published: April 2019

BACKGROUND: Stroke is the most prevalent neurological disease and often leads to disability. Stroke can affect a person’s daily life, for example, its typical feature is the decline in the patient’s upper limbs. In order to reduce the sports injury of stroke patients, the best method is to carry out certain rehabilitation training. OBJECTIVE: In this paper, inverse kinematic analysis and trajectory planning of a modular upper limb rehabilitation exoskeleton are proposed. METHODS: The reverse coordinate system method is applied to solve inverse kinematics of the exoskeleton with a non-spherical joint in the wrist. For verifying the effectiveness of the algorithms, the smooth round-trip trajectory movement in joint place is designed and simulated. RESULTS: The reverse coordinate system method can simplify the calculation process compared with the normal coordinate system. Smooth round-trip trajectory planning is simulated to generate a smooth trajectory curve. CONCLUSIONS: The developed inverse kinematics algorithm and trajectory planning method are effective.

Published: April 2019

BACKGROUND: Compared to laser, light-emitting diodes – non-coherent and divergent light sources requires that the developed optical system support steering and focusing of light on the desired target when acquiring information regarding human tissues. OBJECTIVE: A new optical system with an ultrawide angle was designed to cover large areas of the eye, including facial areas near the eye, in order to overcome the limited field of view of optical systems used for ophthalmology and dermatology applications. METHODS: To achieve a compact and handheld optical system for ophthalmology and dermatology applications, a contrast auto-focus (AF) method must be used, and the weight reduction of the AF group is considered during the design process to satisfy the effective focal length (EFL), back focal length (BFL), and front focal length (FFL) in the proposed optical system using Gaussian-bracket method. RESULTS: The designed optical system can focus from infinity to a magnification of [Formula: see text]0.19 times, representing a distance of 114.359 mm from the first surface of the optical system to the object. The AF lens moving distance from infinity to the minimum distance is approximately 4.984 mm. The full width at half maximum (FWHM) values of the red, green, and blue light-emitting diodes were 16 mm, 35 mm, and 22 mm, respectively. CONCLUSIONS: We have designed an ultrawide-angle optical system for compact optical systems that are suitable for high-performance ophthalmology and dermatology applications.

Published: April 2019

BACKGROUND: Assistant equipment for the visually impaired has a white cane. If the information in the three-dimensional space is transmitted by sound, the blind can draw a three-dimensional space. OBJECTIVE: This study developed “Visual System,” an ambulation aid/guide for the blind that transforms visual-spatial information into auditory information, and verified its utility. Unlike conventional systems, which are in essence simple collision-warning systems, Visual System helps the visually impaired to recreate their surroundings and to be cognizant of the location and proximity of obstacles. METHODS: Ten subjects with normal vision (mean age: 32.4 years; male-to-female ratio: 6 to 4) were selected for blind tests. The subjects were instructed to detect and avoid obstacles presented in various three-dimensional settings. Prior to the tests, experiments were conducted to determine the distance to each subject. Upon completion of Visual System-based detection training, obstacles were presented and tests conducted. For evaluation, the subjects’ vertical position detection, horizontal position detection, distance detection, and overall performance success were each evaluated. RESULTS: The total performance scores ranged between 88 (lowest) and 100 (highest), with a mean score of 91.5. CONCLUSIONS: The results indicate that Visual System as a product can assist the visually impaired in their daily functioning.
