Authors: Linhares Larissa Ingrid Marques , Monteiro Jander Barbosa , Pacheco-Gramata Ana Paula Pinho
Published: May 2021

As abordagens em torno do risco ensejaram, no âmbito científico e nas últimas décadas, amplos debates em virtude dos seus múltiplos usos, envolvendo desde a discussão teórica, possibilidades de avaliação, mensuração, utilização de métodos e métricas variadas, entre outras formas que consideram esta perspectiva. Assim, este artigo objetivou identificar, discutir e analisar algumas destas possibilidades de investigação e interpretação dos diferentes conceitos envolvidos na complexa “equação” do risco, além de elencar exemplos de aplicação, dentre os inúmeros métodos e métricas utilizados na ciência geográfica, para mensurar/avaliar riscos e vulnerabilidades. O estudo foi realizado a partir de consultas à bibliografia especializada, bem como conteúdo estatístico, gráfico e cartográfico contemporâneo, os quais fomentaram discussões pertinentes de cunho teórico e metodológico. Ainda que os vários métodos e métricas aqui mencionados representem apenas uma parcela da produção científica na mensuração do risco e vulnerabilidade em suas múltiplas dimensões, estes proporcionam um amplo debate e elo entre diferentes áreas do conhecimento, contribuindo inclusive para oferecer um importante suporte para reflexão e para os tomadores de decisão.
Comparison of the expansion behavior of atoms and droplets ablated from a β-tricalcium phosphate target under low-pressure ambient H2O gas for hydroxyapatite coating

Published: May 2021

Visualizing the expansion of particles of different size in a laser-ablated plume is useful for understanding the mechanism of the pulsed-laser deposition process. In our previous work that the crystalline hydroxyapatite content in a coating layer decreased with increasing H2O gas pressure. We concluded that ablated atoms and ions, which were immediately changed into crystalline hydroxyapatite, were stopped before reaching the substrate in the H2O pressure range. In the present study, the expansion behavior of ablated droplets and atoms in H2O gas was measured independently. Droplets were also measured via Mie scattering images using a second probe laser beam and were found to not be affected by the ambient gas pressure. However, the excited Ca atoms and ions in this H2O pressure range were effectively prevented from reaching the substrate. These confirm that the decrease in the crystalline hydroxyapatite content was caused by the increase in the ambient gas pressure.

In the advanced Research investigation, anti-cancer agents are an exciting and important part of medicinal chemistry due
to its prevalence in the population. In our present study, Tachyplesin and lactoferrin are antimicrobial peptides isolated
from cow, buffalo and sheep has been shown to kill cancer cells. So we focused to evaluate the peptide as an antibiotic as preliminary work to
provoke and further analyses by testing the effects against cancer cells. In the study, before working on cancer lines, preliminary testing has done
by MTT assay. An MTT assay was characterized to count percent of cell viability with relation to increasing concentrations of peptides. IC50 of
lactoferricin towards HTB9, MFC-7 and PC-3cell lines were calculated at 784.1ug/ml, 697.1 µg/ml and841.2 µg/ml concentrations of anticancer
peptide respectively. IC50 was calculated for the activity of Tachyplesin on all cell lines and recorded to be 452.9 µg/ml, 203.4 µg/ml and 281.0
µg/ml for HTB9, MFC-7 and PC-3 cell lines respectively. Results proved and gave assurance to have viability control effects itself.
Extended Morphological Profile Cube for Hyperspectral Image Classification
Authors: DIAKITE ALOU , JIANGSHENG GUI , XIAPING FU
Published: May 2021

Hyperspectral image (HSI)
classification using convolutional neural network requires a lot of training samples, which is not always available.
Consequently, decreases the classification accuracy due to the overfitting
problem. Many studies have been conducted to solve the issue; however, they
failed to solve it entirely. Therefore, we proposed a new approach to classify HSI
with few training samples using a convolutional neural network in that context.
The proposed approach employed an extended morphological profile cube (EMPC) to
extract rich spectral-spatial features and then used a 3D densely connected network for classification. Besides, we used sparse principal component analysis to reduce the high spectral dimension
of HSI. Experiments results on Indian Pines (IP) and University of Pavia (UP)
datasets proved the efficiency of the proposed approach. It increased the OA by
2.61% - 13%
and the Kappa coefficient by 2.68% - 15:51% on IP dataset and increased the OA by 0.17%
- 11%
and the Kappa coefficient by 0.23% - 19% on UP dataset, which is superior to some
state-of-art methods.
Electrotactile feedback applications for hand and arm interactions: A systematic review, meta-analysis, and future directions
Authors: Kourtesis Panagiotis , Argelaguet Ferran , Vizcay Sebastian , Marchal Maud , Pacchierotti Claudio
Published: May 2021

Haptic feedback is critical in a broad range of human-machine/computer-interaction applications. However, the high cost and low portability/wearability of haptic devices remain unresolved issues, severely limiting the adoption of this otherwise promising technology. Electrotactile interfaces have the advantage of being more portable and wearable due to their reduced actuators' size, as well as their lower power consumption and manufacturing cost. The applications of electrotactile feedback have been explored in human-computer interaction and human-machine-interaction for facilitating hand-based interactions in applications such as prosthetics, virtual reality, robotic teleoperation, surface haptics, portable devices, and rehabilitation. This paper presents a technological overview of electrotactile feedback, as well a systematic review and meta-analysis of its applications for hand-based interactions. We discuss the different electrotactile systems according to the type of application. We also discuss over a quantitative congregation of the findings, to offer a high-level overview into the state-of-art and suggest future directions. Electrotactile feedback systems showed increased portability/wearability, and they were successful in rendering and/or augmenting most tactile sensations, eliciting perceptual processes, and improving performance in many scenarios. However, knowledge gaps (e.g., embodiment), technical (e.g., recurrent calibration, electrodes' durability) and methodological (e.g., sample size) drawbacks were detected, which should be addressed in future studies.

We categorize the different electrotactile systems according to their type of stimulation and implementation/application. We also present and discuss a quantitative congregation of the findings, so as to offer a high-level overview into the state-of-art and suggest future directions. Electrotactile feedback was successful in rendering and/or augmenting most tactile sensations, eliciting perceptual processes, and improving performance in many scenarios, especially in those where the wearability/portability of the system is important. However, knowledge gaps, technical drawbacks, and methodological limitations were detected, which should be addressed in future studies.

"Breast cancer is a major concern in women’s health in Mainland China. Literatures demonstrates that women with breast cancer (WBC) need to pay much effort into resisting stigma and the impact of treatment side-effects; they suffer from overwhelming consequences due to bodily disfigurement and all these experiences will be unbeneficial for their mental and sexual health. However, related studies in this area are rare in China. The objectives of this study are 1) To understand WBC’s treatment experiences, 2) To understand what kinds of support should be contained in a transdisciplinary intervention framework (TIP) for Chinese WBC through the lens that is sensitive to gender, societal, cultural and practical experience. In this study, the feminist participatory action research (FPAR) approach containing the four cyclical processes of action research was adopted. WBC’s stories were collected through oral history, group materials such as drawings, theme songs, poetry, handicraft, storytelling, and public speech content; research team members and peer counselors were involved in the development of the model. This study revealed that WBC faces difficulties returning to the job market and discrimination, oppression and gender stereotypes are commonly found in the whole treatment process. WBC suffered from structural stigma, public stigma, and self-stigma. The research findings revealed that forming a critical timeline for intervention is essential, including stage 1: Stage of suspected breast cancer (SS), stage 2: Stage of diagnosis (SD), stage 3: Stage of treatment and prognosis (ST), and stage 4: Stage of rehabilitation and integration (SRI). Risk factors for coping with breast cancer are treatment side effects, changes to body image, fear of being stigmatized both in social networks and the job market, and lack of personal care during hospitalization. Protective factors for coping with breast cancer are the support of health professionals, spouses, and peers with the same experience, enhancing coping strategies, and reduction of symptom distress; all these are crucial to enhance resistance when fighting breast cancer. Benefit finding is crucial for WBC to rebuild their self-respect and identity. Collaboration is essential between 1) Health and medical care, 2) Medical social work, 3) Peer counselor network, and 4) self-help organization to form the TIF for quality care. The research findings are crucial for China Health Bureau to develop medical social services through a lens that is sensitive to gender, societal, cultural, and practical experiences of breast cancer survivors and their families."

"Over the years, research has demonstrated that psychotherapy is an effective treatment in different psychopathological conditions. However, which are the mechanisms or processes involved in therapeutic change that could explain its efficacy are not yet clear. The Assimilation of Problematic Experiences Model describes change in therapy as a process that occurs through the gradual assimilation of problematic experiences in the self – higher levels of assimilation seem to be associated with a better outcome at the end of therapy. However, little is known about the contribution of this process to the maintenance of therapeutic gains after the end of therapy. In the current study we aimed to explore how the level of assimilation achieved throughout therapy is associated with relapse prevention after treatment. We analyzed two good outcome cases of Emotion-Focused Therapy, previously diagnosed with depression: one case that remained asymptomatic and another that relapsed one year and a half after the end of therapy. The Assimilation of Problematic Experiences (APES) was used to assess the assimilation levels achieved and the Beck Depression Inventory-II (BDI-II) was used to assess the intensity of depressive symptoms. Five therapeutic sessions and three follow-up sessions were rated using the APES. The results showed that higher APES levels were associated with lower intensity of symptoms at the end and after therapy termination, being associated with relapse prevention in depression. These results suggest that a complete assimilation of the problematic experiences may help clients to maintain therapeutic gains reducing the probability of relapsing in depression."

"Sexual transmission of HIV among Men who have Sex with Men (MSM) is believed to be one of the sources of the AIDS epidemic. Nowadays, governments, communities, and NGOs are taking action to prevent its spread by assisting and educating groups of MSM in their countries. This assistance involves experts in many fields of study, including psychology. In the field of psychology, psychoeducation is believed to be one of the ways to assist the MSM groups. In September to December 2019, the authors conducted a mentoring effort to the MSM community at the MSM community gathering location called Gang Pattaya, in the city of Surabaya, the second largest and densely populated city in Indonesia The existence of this community is disguised by the general public, but is well known by NGOs. Community members do MSM out of their liking, although some do it in exchange for money. However, safety factors, such as using condoms for MSM, are not a priority for this community. They do MSM whether they receive a reward or not, just out of a boost of pleasure. There is no attempt to find out the health of the partner once they are attracted to each other. In general, they do not know whether they are infected with HIV. Most of them feel healthy and since they do not show any symptoms, they think it is not necessary to get tested. In the mentoring process, we conduct psychoeducation, which begins with an approach to certain individuals so that they are comfortable with our presence, then increasing awareness of safer sex behavior for HIV prevention for groups in the form of counseling using the Theory of Reasoned Action (TRA) approach. Counseling is carried out in various forms including roleplay, games, and seminars. The number of participants was 11 people as agents of changes of the community, varying from 19 - 47 years old. Pretest related to knowledge of safer sex was carried out before conducting the intervention and post-test after the intervention. The normality test used is the Shapiro-Wilk analysis. Different tests on the data obtained were carried out using the non-parametric Wilcoxon Signed Ranks Test. None of the participants had lower post-test knowledge scores than the pre-test. Prestest and post test for safer sex behavior showed 2 participants with safer sex behavior did not change. Both belong to the senior group, while other participants have an improvement in their safer sex behavior. These findings suggest that intervention programs for MSM as an effort to reduce HIV transmission should pay attention to affective and cognitive coping strategies."

"Introduction. The rapid spread of coronavirus disease 2019 (COVID-19) has created unprecedent global challenges for health systems. National Healthcare Systems Hospitals adopted protective measures and medical equipment resources, exposing healthcare workers at risk for stress syndromes, subclinical mental health symptoms, and long-term occupational burnout. Health workers have had to deal with the most severe clinical cases in intensive care specialized operative division. Since the first months of the epidemic spread, some studies have established shown that nurses have shown symptoms of severe anxiety associated with peritraumatic dissociative experiences. Most of the studies examined the emotional impact of COVID 19 on health professionals but did not focus on different consider professionals roles and hospital departments workload. Objective. The aim of our study was to analyze the emotional characteristics of health workers during the II wave of coronavirus (November-December 2020), comparing the frontline (COVID 19) and second line (chronic diseases) hospital divisions and analyzing the differences between the health roles. Methods. We conduct a pilot study among health-workers. A sample of 28 healthcare workers (aged 23-62 years) were recruited from frontline and secondline hospital departments (L’Aquila, IT). The administered psychological battery was composed of n. 4 self-reports evaluating emotional variables (depression, anxiety, and stress) (DASS-21), personality traits (BFI-10), burnout risk (MBI), and perceived stress (PSS). Results. The results highlighted significant differences: older health workers were found to be more vulnerable than those who younger health workers; another interesting point was that healthcare workers serving in frontline wards showed symptoms of depersonalization. No significant difference for the type of role held. Conclusions. A prevention program should be activated to preserve frontline and older workers mental health. Earlier support could mitigate the effect of the pandemic experience, reducing the risk for emotional health workers' fragility."

"This article presents data from a study conducted over the course of two weeks: the last week of the lockdown and the first week after the lockdown was lifted. The study participants (undergraduate and graduate students, n=227, mean age of 21.8, 71.7% females) rated their perceptions of various aspects of the pandemic (online COVID-19 Questionnaire), as well as the problems that they experienced in the beginning and middle of the lockdown (retrospective assessments) and at the end of the lockdown (current assessments). A brief HEXACO inventory was used to measure personality traits. The results were compared with data obtained in the study conducted during the first three weeks of the lockdown. Its participants (undergraduate and graduate students, n=617, mean age of 20.4, 74.2% females) had filled out an online COVID-19 Questionnaire and a brief HEXACO inventory. The objective of the study was to identify changes in the respondents’ well-being and behavior during the lockdown, and the role of personality traits in this process. The main results of the study were as follows: Retrospective assessments of the Danger of COVID-19 and the Fear of Getting Sick relating to the beginning of the lockdown did not contradict the current assessments from that period. The perception that the lockdown brought not only restrictions but also new opportunities dropped sharply between the beginning and the middle of the lockdown and continued decreasing; concurrently, the significance of negative factors increased. Various aspects of disorganization in life were most evident around the middle of the lockdown; disorganization at the end of the lockdown declined, but remained higher than at the start of the lockdown. Perceptions of the Negative Aspects of the Lockdown, Fear of Getting Sick, and Disorganization had a positive correlation with Emotionality and a negative correlation with Conscientiousness at all stages of the lockdown."

"The start of 2020 marked a fresh beginning when people moved forward with new resolutions, all hoping for the best in their career, family, relationships, and academic pursuits. All those wishes were disrupted, however, by the Covid-19 pandemic, which has especially affected university students regarding their academic goals. The new learning norms that were adopted in universities to contain the spread of the pandemic have caused worry, anxiety, and stress in many students. To deal with these unexpected circumstances, university students must augment their inner strengths to enhance their resiliency during the Covid-19 pandemic. To better understand the situation, this study examined previous adversity, happiness and religious faith that were predicted to enhance students’ resiliency. There were 415 university students in Sabah, Malaysia participated in the study. The mean age was 21.96 years (SD=4.08). Among the participants, there were 330 females (79.50%), 84 males (20.20%) and one person (0.2%) who did not disclose a gender. The study found that students who were happier and stronger in religious faith tended to be more resilient while the experience of many previous adversities had a significant negative effect on students’ resiliency. Based on these findings, we hope that more university programs will be devised to elevate students’ happiness, build stronger faith and offering psychological programs for students who have experienced many previous difficulties."

"The phenomenon of marriage is one of the little-studied questions of family psychology. The resolution of the contradiction between the need of modern society to form complete and adequate ideas about the marital role among students and the need to identify socio-psychological factors that influence the development of ideas about marriage determines the problem of research. The purpose of the study is to identify the features of ideas about marriage (Ideal husband, Ideal wife) depending on the structure of valuable orientations of young women in early adulthood. Methods of research. Theoretical and methodological literature analysis, questionnaire, psycho-diagnostic methods (the questionnaire “A Value and Availability Ratio in Various Vital Spheres Technique” by E.B. Fantalova, the method of Semantic Differential, developed by Charles E. Osgood, projective technique of ""Incomplete Sentences"", the questionnaire ""Role Expectations and Claims in Marriage"" by A. N. Volkova); mathematical and statistical data processing methods. During the analytical stage we used mathematical and statistical methods that allowed us to establish the reliability of the research results. All calculations were performed using the IBM SPSS Statistics 21 computer program. The analysis included descriptive statistics, cluster analysis (K-means method), Kolmogorov-Smirnov test for one sample, Shapiro-Wilkes criterion, and correlation analysis. The study involved 310 female students in age from 20 to 22 from Astrakhan State University and the Astrakhan Branch of the Russian Presidential Academy of National Economy and Public Administration. It was found that among young female students 45 people (14.5 %) are focused on the values of professional self-realization, 59 people (19 %) are focused on gnostic and aesthetic values, and 206 people (66.5 %) are focused on the values of personal happiness. The results showed that the concepts of marriage have both common features and specific features due to the influence of the structure of valuable orientations of the respondents. Ideas about marriage are characterized by fragmentary formation of emotional and behavioral components, in some cases the presence of cognitive distortions. The obtained results actualize the importance and necessity of psychological and pedagogical support of the process of family self-determination of students, the formation of complete and adequate ideas about marriage in the conditions of the educational environment of the university."

"Police officers are some of the first professionals that might have direct interaction with individuals with mental illnesses. Statistics show that from 2017 to 2020 about 3986 individuals in the United States were fatally shot by police officers (Statista, 2021). These reports indicate that at least 25% and as many as 50% of all fatal shootings involved individuals with untreated severe mental illness. The purpose of this pilot study was to test the effectiveness of a five-day psycho-educational mental health awareness training in enhancing law enforcement officers’ knowledge about mental illness, and their perceptions towards mentally ill individuals using a pretest-posttest design. The Community Attitudes Towards the Mentally Ill (CAMI) scale was used to measure participants’four mental health attitudinal domains - authoritarianism, benevolence, social restrictiveness, and community mental health ideology. The results indicate that at the completion of the training there was an increase in participants’ confidence about their knowledge of the mentally ill individuals and mental illness conditions. However, the results also indicate a slight decrease in participants' mental illness social restrictiveness sentiment after the completion of the training. Additionally, the results also show a correlation between demographic variables and some of the domains. Implications for practice are discussed."

"Dyslexia is one of the most frequent specific learning disorders which has often been associated with deficits in phonological awareness mainly caused by auditory and visual inabilities to recognize and discriminate phonemes and graphemes within words. Neuroimaging techniques like EEG recordings have been widely used to assess hemispheric differences in brain activation between students with dyslexia and their typical counterparts. Although dyslexia is a lifelong disorder which persists into adulthood, very few studies have been carried out targeting in adult population. In this study, we examined the brain activation differences between 14 typical (control group) and 12 university students with dyslexia (experimental group). The participants underwent two tasks consisting of 50 3-word groups characterized by different degrees of auditory and visual distinctiveness. The whole procedure was recorded with a 14-sensor sophisticated wearable EEG recording device (Emotiv EPOC+). The findings from the auditory task revealed statistically significant differences among the two sets of groups in the left temporal lobe in ?, ? and ? rhythms, in the left occipital lobe in ? rhythm, and in the right prefrontal area in ?, ? and ? rhythms, respectively. The students with dyslexia reported higher mean scores only in ? rhythm in the left temporal lobe, and in ?, ? and ? rhythms in the right prefrontal area. Concerning the visual task, statistically significant differences were evident in the left temporal lobe in ?, ? rhythms, in the occipital lobe in ?, ? and ? rhythms, in the parietal lobe in ? rhythm, and in the right occipital lobe in ?, ? and ? rhythms. The students with dyslexia reported higher mean scores only in the ? rhythm of both the left and right occipital lobe. The results indicate that there are differences in the hemispheric brain activation of students with or without dyslexia in various rhythms in both experimental conditions, thus, shedding light in the neurophysiological discrepancies between the two groups. It also lays great emphasis on the necessity of carrying out more studies in adult population with dyslexia."

"The purpose of this study was to examine the factors that influence an individual’s choice to share personal information online. Specifically, the role of age, gender, personality, overall media exposure, and perceived risks and benefits were examined in relation to a willingness to share personal information that differed in sensitivity (high school grades, medical records, income) and differed in target audience (social media, online store, general public). A total of 202 individuals participated in this survey study. The majority were young (M age = 22.46 years, SD = 5.77), single (83.7%), women (80.7 %), with at least some post-secondary education (90.1%). A series of hierarchical regression analyses were conducted. The results indicated that willingness to share personal information on social media was predicted by having higher scores on the personality traits of extraversion, agreeableness, and negative emotionality. Higher scores on perceived purchase benefits and total media exposure also predicted willingness to share personal information on social media. In terms of willingness to share personal information with an online store, total media exposure was a significant predictor along with higher extraversion and lower conscientiousness scores. Finally, willingness to share personal information with the general public was predicted by overall media exposure. Participants generally believed that there were risks involved in sharing personal information, but these risks were considered to be slight. As well, they only slightly disagreed when asked if the internet could be trusted, and were neutral on whether there were purchase benefits to providing personal information."
THE DARKSIDE OF IDIOSYNCRATIC DEALS: HUMANISTIC VERSUS NEOLIBERAL TRENDS AND APPLICATIONS
Authors:   Institute of Psychology, University of Innsbruck (Austria), Hornung Severin , Höge Thomas
Published: May 2021

"Theory-building on workplace flexibility is extended, based on a critical Human Resource (HR) systems framework and paradox (conflict) perspective on employee-oriented vs. capacity-oriented flexibility. Differentiated are variabilities in HR practices by: a) content (functional, temporal, spatial, numerical, financial); b) control (employer, employee); and c) creation (top-down, bottom-up). Hybrid types of bottom-up initiated and top-down authorized flexibility, idiosyncratic deals (i-deals), describe mutually beneficial, negotiated agreements on non-standard working conditions between employees and employer. If their real-world manifestations reflect idealized assumptions, however, remains obscure. Integrating institutional logics, HR systems embody values of humanistic ideals vs. neoliberal ideology: (1) individuation vs. individualism; (2) solidarity vs. competition; (3) emancipation vs. instrumentality. Reflecting these antipodes, construed ideal-type and anti-type i-deals facilitate: (a) self-actualization vs. self-reliance (needs vs. interests); (b) common good vs. tournament situations (triple-win vs. winner-take-all); (c) social transformation vs. economic rationalization (development vs. performance). In humanistic management theory, i-deals increase employee-oriented flexibility, but, in reality, risk being co-opted for economic rationalization and divisive labor-political power strategies. Antagonistic applications involve: humanization vs. rationalization goals; egalitarian vs. elitist distribution; relational vs. transactional resources; need-based vs. contribution-based authorization; procedural vs. distributive justice; supplementing vs. substituting collective HR practices. Instrumental adoption in high-performance work environments likely facilitates harmful internalizations as subjectification and self-exploitation."

The main role in reducing the noise generation of unmanned aerial vehicles is played by aeroacoustic improvement of their power plant. To identify the acoustic field generated by the rotation of the impeller, which is used on an unmanned aerial vehicle of a quadcopter type, numerical modeling was carried out with the identification of the turbulent structure of the flow using the Large Eddy Simulation (LES). To calculate the noise, the Fox Williams-Hawkings (FW-H) integral method was applied, which makes it possible to determine the aeroacoustic characteristics in the far flow field. Using this technique, the noise level at various points was determined, a spectral analysis of the noise was carried out, and the directional pattern of acoustic radiation was plotted for various speeds of rotation
of the propeller in hovering mode.

The calculation of noise generated by a jet of viscous compressible gas flowing out from a conical nozzle is considered.
The calculations used the implicit version of the LES (Implicit LES, ILES), in which the role of the subgrid turbulence model performs
numerical dissipation used finite-difference scheme. The distributions of the gas-dynamic and acoustic characteristics of the jet upon
changing the conditions of its outflow are discussed. The analysis of the modal composition of the received noise is carried out and the
correspondence between the features of the received directionality of the noise is determined by its various components and sources.
The numerical simulation results are compared with the available experimental and calculated data.

When hygienic standards for regulating noise factor in the environment are developed in accordance with the existing regulatory-methodical base, it is necessary to take into account all possible sources of noise that are located in close proximity to an
object that produces adverse effects (noise exposure). Noise produced by such sources is taken into account as background one. It is especially important to take background noise into account when designing zones with specific purpose for their use (specific zones) and in a case when noise is a priority exposure factor (in particular it is true for sanitary protection zones (SPZ) and zones near airports and airfields (airport zones or AZ) or when examining project data. The present work generalizes methodical approaches to taking background noise into account and also dwells on a procedure for combining calculated and instrumental data via energy summation. It contains results obtained via testing this combined methodical approach on a large industrial enterprise located in a large industrial city. As per acoustic calculation results noise levels varied from 29.7 dBA to 44.4 dBA within boundaries of an established sanitary protection zone. Instrumental measurements performed in a zone influenced by the examined enterprise at two control points located in the closest residential area showed noise levels varying from 40-43 dBA (at night) to 48-50 dBA (during a day). Having compared calculated and field data, we obtained discrepancies for the control points that varied from 1.0 dBA to 27.0 dBA and it allowed obtaining summated (aggregated) noise level varying from 40.4 to 51.0 dBA accordingly at the control points within the SPZ. Our experience and methodical approaches to calculating and assessing background noise exposure will allow meeting legal requirements on taking side sources of noise exposure into account as background noise within specific zones and passing sanitary-epidemiologic examinations with satisfactory results.

DETERMINATION OF MONOPOLE AND DIPOLE SOURCES OF FLOW AROUND A CYLINDER USING A VIRTUAL MICROPHONE ARRAY
Authors: Ershov Victor , Khramtsov Igor , Kustov Oleg
Published: May 2021

In this paper, the problem of localization of noise sources of flow around a cylinder was considered on the basis of a computational experiment using a virtual 54-channel microphone array. Numerical simulation was performed using the computational
fluid dynamics software ANSYS Fluent. Several spatial orientations of the cylinder were considered for the generation of dipoles with different directions. Simulation of a simplified two-microphone azimuthal decomposition technique (ADT) is performed to determine the sound pressure level of the generated dipoles at a vortex shedding frequency of 1450 Hz. A procedure of localization of the noise of the flow around a virtual cylinder was performed using monopole and dipole beamforming algorithms. It was found that the numerical simulation results are in good agreement with the data obtained by other researchers, both in terms of the sound pressure level and the results of the localization of dipoles in space.

Рассмотрены вопросы создания системы поддержки принятия решений при составлении паспорта дороги. Одной из задач, решаемых в процессе паспортизации автомобильной дороги, является заполнение данных о наличии и расположении искусственных сооружений, дорожных инженерных устройств, в том числе дорожных знаков. Система предназначена для автоматизированного анализа видеопотока с целью выделения кадров, содержащих дорожные знаки, а также последующей классификации найденных знаков. Приведена оригинальная двухэтапная система извлечения и классификации изображений, содержащих дорожные знаки. Алгоритм обнаружения требуемых изображений базируется на использовании вейвлет-преобразований Хаара и концепции интегрального изображения, что позволяет максимально быстро находить требуемые кадры. Оригинальность применения признаков Хаара состоит в том, чтобы использовать только 2 прямоугольных фильтра (горизонтальный и вертикальный) в разных масштабах: 2x2, 4x4, 8x8 и 16x16. Последующая обработка данных, целью которой является классификация найденных изображений, осуществляется с применением искусственной нейронной сети. Актуальность разработки подобной системы поддержки принятия решения определяется необходимостью обработки больших объемов видеоданных. Система позволяет в значительной мере исключить фактор пользовательских ошибок, что очень важно, так как полученные данные влияют на безопасность дорожного движения

The article considers issues of creating a decision support system for the preparation of the passport of a road. One of the tasks solved in the process of passporting a motorway is to fill data on the presence and location of structures, road engineering devices, including road signs. The system is designed for automated analysis of the video flow to highlight frames containing road signs, as well as the subsequent classification of the found characters. We give an original two-stage system for extracting and classifying images containing road signs. The detection algorithm for the desired images is based on the use of Haar's wavelet transforms and the concept of an integrated image, which allows one to get the required frames as quickly as possible. The originality of the use of Haar signs is to use only 2 rectangular filters (horizontal and vertical) on different scales: 2x2, 4x4, 8x8 and 16x16. Subsequent data processing, the purpose of which is the classification of the found images, is carried out using an artificial neural network. The relevance of the development of such a decision support system is determined by the need to process large volumes of video data. The system allows one to largely eliminate the factor of user errors, which is very important since the data obtained affect the safety of the road
