GIANT OVARIAN CYST PRESENTING AS EPIGASTRIC MASS-A CASE REPORT
Authors: Santhi B. , Vikraman V. G.
Published: May 2021

Giant ovarian cysts (GOCs) are rare tumours of the ovary presenting with diameters greater than 10 cm.
Ovarian cysts are generally asymptomatic at early stages causing symptoms only after reaching
enormous dimensions, and consequently they are often diagnosed late. Majority of GOCs are benign and are generally treated
by surgical excision either by cystectomy or salpingo-oophorectomy. Malignant ovarian cysts (MOC) constitute over 10% of
GOCs and are treated by total abdominal hysterectomy with bilateral salpingo-oophorectomy ± omentectomy .We
encountered a 65 years old female who presented with the history of progressively increasing distension of upper abdomen for
last 6 months. Abdominal examination revealed a uniformly large cystic mass in the epigastrium with ill-dened lower border.
There was uniform fullness in both the anks. Contrast enhanced Computed Tomography suggested large well dened intra
peritoneal cystic lesion with few thin internal sepatations probably cystic lesion from the ovary. Laparotomy was done and there
was a large cystic mass arising from the pelvis which was excised with membranes intact. Bilateral oophorectomy with
appendectomy was done. Histologically it was found to be mucinous cystadenoma.

Published: May 2021

Colorectal cancer (CRC) is the third most common tumor type worldwide with approximately 1.8 million
new cases diagnosed per year. Despite the high incidence of newly diagnosed cases, the majority (70%-
80%) of these tumors are respectable. These tumors can present as an incidental ndings on screening colonoscopy, with
anemia symptoms such as general weakness and fatigue ( for right sided- tumors) or changes in bowel habits ( for left sided
tumors). In advanced cases, loss of weight and loss of appetite are also common presenting symptoms. Less common, yet
emergent presentations include large bowel obstruction, severe gastrointestinal hemorrhage and free intra-abdominal
perforation. Synchronous CRC (SCRC) tumors, dened as two or more primary tumors existing independently of one another,
have an incidence rate of 2.3% - 12.4% of overall CRC with male predominance. Presentation of these tumors is usually identical
to presentation of solitary CRC. Emergency surgical presentation, with two different surgical indications for operation is very
rare. Herein, we present a case of SCRC tumor in a 32-year-old man, with indication for emergent surgery being ileo-caecal
intussusceptions but incidentally was diagnosed to have sigmoid colon growth .

"The present study was conducted to explore the perception and views of primary care staff about Depression related Stigma and Discrimination. The Basic Qualitative Research Design was employed and an In-Depth Semi-Structured Discussion Guide consisted of 7 question was developed on the domains of Pryor and Reeder Model of Stigma and Discrimination such as Self-Stigma, Stigma by Association, Structural Stigma and Institutional Stigma, to investigate the phenomenon. Initially, Field Test and Pilot study were conducted to evaluate the relevance and effectiveness of Focus Group Discussion Guide in relation to phenomena under investigation. The suggestions were incorporated in the final Discussion Guide and Focus Group was employed as a data collection measure for the conduction of the main study. A purposive sampling was employed to selected a sample of Primary Care Staff (Psychiatrists, Medical Officers, Clinical Psychologists and Psychiatric Nurses) to elicit the meaningful information. The participants were recruited from the Department of Psychiatry of Pakistan Medical and Dental Council (PMDC) recognized Private and Public Sector hospitals of Lahore, having experience of 3 years or more in dealing with patients diagnosed with Depression. However, for Medical Officers, the experience was restricted to less than one year based on their rotation. To maintain equal voices in the Focus Group, 12 participants were approached (3 Psychiatrist, 3 Clinical Psychologists, 3 Medical Officers and 3 Psychiatric Nurses) but total 8 participants (2 Psychiatrists, 2 Medical Officers, 3 Clinical Psychologists And 1 Psychiatric Nurse) participated in the Focus Group. The Focus Group was conducted with the help of Assistant Moderator, for an approximate duration of 90 minutes at the setting according to the ease of the participants. Further, it was audio recorded and transcribed for the analysis. The Braun and Clarke Reflexive Thematic Analysis was diligently followed through a series of six steps such as Familiarization with the Data, Coding, Generating Initial Themes, Reviewing Themes, Defining and Naming Themes. The findings highlighted two main themes i.e., Determining Factors of Mental Health Disparity and Improving Treatment Regimen: Making Consultancy Meaningful. The first theme was centered upon three subthemes such as Lack of Mental Health Literacy, Detached Attachment and Components of Stigma and Discrimination. The second theme included Establishing Contact and Providing Psychoeducation as a subtheme. The results manifested the need for awareness-based Stigma reduction intervention for Primary Care Staff aims to provide training in Psychoeducation and normalization to reduce Depression related Stigma and Discrimination among patients diagnosed with Depression."

"The article is the review of the available research papers on anxiety, depression, stress and signs of PTSD in pregnant women during the COVID-19 pandemic. Articles were searched in the databases of Scopus, Web of Science, EBSCO, APA using the keywords ""pregnancy"", ""COVID-19"", ""anxiety"","" depression"","" stress"","" PTSD"". For this article review we selected only those research studies that have comparatively large samples, with the most widely used measures: State and Trait Anxiety Inventory (STAI), Generalized Anxiety Disorder (GAD-7), Edinburg Postpartum Depression Scale (EPDS), and Impact of a Traumatic Event Scale (IES-R). In these studies levels of anxiety, depression and PTSD are either compared to the existing cut-off scores for these disorders in the literature or in COVID-19 and pre-COVID cohorts of pregnant women. Some papers include not only women during pregnancy but also postpartum. Data here are presented only on pregnancy. The results show that 22% to 68% of pregnant women experience moderate to severe anxiety, and it is two to five times more than the prevalence of anxiety in the literature. The state anxiety has increased more compared to trait anxiety. 14.9%-34.2% of women report on clinically significant levels of depression, and it is twice higher than the pre-existing data. About 10.3% of pregnant population have PTSD signs which falls into a moderate range. The levels of anxiety, depression and PTSD are significantly higher in COVID-19 cohorts than in pre-COVID samples. The most predicting factor for anxiety, depression and PTSD is the pre-existing mental health disorder of anxiety or depression."
BUFFERING EFFECT FOR 2ND COVID-19 LOCKDOWN: THE ROLE OF ACADEMIC E-LEARNING ADOPTION AMONG GENERATION Z
Authors:   Department of Life Health and Environmental Sciences, University of L’Aquila (Italy), Ranieri Jessica , Guerra Federica , Di Giacomo Dina
Published: May 2021

"Background. The undergraduate community is composed of Generation Z members who constitute a social generation of digital natives who are technologically skilled. Their widespread exposure to technology accounts for their comfort with and strong knowledge of digital media. The government adoption of e-learning in academic education during the coronavirus disease (COVID-19) pandemic may be beneficial to such digitally skilled individuals. Some studies have underscored the e-learning adoption adverse psychological impact on the mental health of the younger generation. In fact, the findings underscore an increase in psychological distress, excessive fear of infection, pervasive anxiety, frustration and boredom, a high level of stress, and post-traumatic stress symptoms. We aimed to detect the protective factor for academic community during social restriction for pandemic in 2nd Italian lockdown analysing the adaptive behaviour of undergraduate in 3 field panels of academic education (life sciences, physical and engineer sciences, human and social sciences). We aimed to determine the psychological impact of prolonged e-learning on emotional regulation among undergraduate students. A secondary objective was to identify key components for preventive interventions targeted toward the academic community by investigating the buffering effect of e-learning in academic education on exposure to the pandemic. Methods. An online cross-sectional survey was conducted on 570 university students (aged 18–26 years) pursing degrees in life sciences, physical and engineering sciences, and social sciences in Italy. They were recruited using snowball sampling. We administered emotional (PDEQ, CSSQ, CAS), personality traits (BFI-10) and affinity for e-learning (AEQ) measures. Results. Our findings suggest that a majority of the university students developed peritraumatic dissociative experience and stress, but not dysfunctional coronavirus anxiety during the 2nd COVID-19 lockdown in Italy. Nevertheless, the present findings also highlight the fragility of younger Gen Z undergraduate students who are beginning their academic journey amid the COVID-19 pandemic. Further, coronavirus distress significantly predicted mental health through the mediating effect of personality traits and e-learning affinity. Conclusions. Therefore, health care professionals are encouraged to implement psychological support interventions that strengthen one’s ability to manage stressful situations and reinforce their status as a digital native. Consequently, they may realize the power of their personal strengths, which in turn may mitigate their stress and peritraumatic dissociative experience when they deal with challenges, enhance their competence, and enable them to adopt effective coping strategies."

"Flexible learning has been associated with e-learning, even before the COVID-19 pandemic. Flexible learning gives the students large degrees of freedom to learn what, when, how and where they want. The aim of this study was to evaluate students’ preferences in e-learning and traditional classroom teaching, and was conducted from October 2019 to January 2020. Students from four courses were assigned randomly to two groups, an online and a classroom group. The study included two phases: three lectures by the lecturer (podcasts vs. classroom) and seven classroom units with student presentations and discussions. Performance and different personal characteristics and attitudes of 93 students were examined. Knowledge on the course topic was measured before the first lecture took place (t1), after the three lectures (t2) and after the following seven units (t3). Statistical analyses found no performance differences between the two groups (online/classroom); this held true for all three points in time. All students appreciated the opportunity of an intermediate exam at t2 (a change in comparison to former courses on the topic). Qualitative data showed that students felt a need for interaction with their colleagues and the lecturer, which they decided could be better fulfilled in the classroom, whereas the flexible learning setting had advantages for the exam preparation (e.g. repeating listening to the podcasts, taking breaks and learning tempo). Students’ arguments fit well to previous literature. Altogether, the study gives valuable insights into the didactic design of flexible learning."
PERSON-ENVIRONMENT MISFIT AND MENTAL DISORDER AMONG PHD STUDENTS: THE MEDIATING ROLE OF MEANINGFUL WORK

Published: May 2021

"In organizational psychology, the authors’ awareness of the concerns about the current academic working conditions and their potential impacts on PhD students’ mental health is increasing. Accordingly, authors have witnessed increased the attention to PhD students’ perception of their fit with the environmental conditions, i.e., organizational policies, co-workers’ and supervisors’ relations and supports, as an antecedent of their PhD experience. In particular, such environmental conditions seem to be related to the high diffusion of state anxiety and depression among PhD students that perceive a certain level of misfit between them and the environment. However, studies suggested that, despite the working conditions, in the presence of positive experience at work, such as meaningful work, individuals are less at risk of developing mental disorders as well as of quitting their job. Indeed, meaningful work construct regards a positive individual phenomenon of experience and perception of meaningfulness at work. Then, it might be a potential experience that might mitigate the experience of negative states at work. The present paper aims to address the current need for knowledge by involving a literature review of the role played by meaningful work in the PhD experience. Then, the paper explores the potential mediational role of meaningful work between the path from P-E misfit and mental disorders’ symptoms and students’ intention to quit. A cross-sectional study has been devised via the use of an online questionnaire with self-report measures on P-E misfit, meaningful work, mental health disorders symptoms, and intention to quit. In a sample of N = 251 Italian PhD students, the results showed a prevalence of three mental health disorders symptoms, i.e., depression, anxiety and hostility, among doctorate students, which resulted to be positively related to the levels of P-E misfit. Then, the results showed a negative mediating role of meaningful work on the paths from P-E misfit to (a) mental disorders and (b) intention to quit. Finally, the paper advances further steps for research as well as for practical implications for supporting PhD students."

"The development of gay identity sexual among Malaysian gay men were not discussed openly in this country. This is because the government do not approve same sex orientation lifestyle. However, gay men exist in many communities in this country and they are living freely as a citizen and work in the country like others. Malaysia is one of the countries that openly against the Lesbian, Gay, Bisexual, Transsexual and Queer (LGBTQ). Nevertheless, they continue to develop their sexual identity as a part of their lives which at the same time causes a great distress in them. Thus, their decision to identify themselves as gays takes huge courage and effort. These courage and effort were found not only just intricately, since it involves emotional and social support from their family, friends and communities. It is also believed that this social support might help gay men to develop their self-efficacy as well. Therefore, it is in the interest of the researchers to explore about self-efficacy by looking at emotional and social support they received and its relation to the development of sexual identity among the gay men who lives in Malaysia. In this qualitative research, semi structured questions were developed to explore sexual identity development among the gay men. Six (6) respondents who have identified themselves as gay, aged between 21- 44 years old, from different walk of life were interviewed. Data were analysed using thematic analysis. Our study has found that emotional and social support, are the important factors that contribute to their self-efficacy and help them in developing their sexual identity."

"The setting of goals and ways to achieve them is a possibility that the human species acquired with the development of language. Planning and executing, however, are different behaviors, as are the circumstances that favor or prevent them. Getting into graduate school in Brazil is still surrounded by uncertainties, including those regarding the future job market. In addition, the tasks required throughout the course present challenges for most students. Resilience, a necessary characteristic for overcoming adversity, can be investigated through different factors that favor decision-making and maintaining persistence towards the achievement of goals. In addition, self-knowledge mediates the development of these factors. Based on these fundamentals, we aimed to identify the impacts of storytelling videos, accompanied by reflection scripts, on the self-knowledge of students in graduate courses in Belém, in northern Brazil. For that, six videos, six reflection scripts and an on-line interview were prepared by the research group, in addition to an invitation to participate and a participant consent form. The videos were stored on the YouTube platform, and the other materials were made available through Google Forms. The social network WhatsApp was used to forward our invitation, the consent form and the links that allowed access to data collection instruments. Among students who underwent the initial procedures, ten went through all the steps and became participants in this research. The responses made it possible to relate the participants contact with the characters of the stories told in the videos to reflections on the need to pay more attention to themselves, in the sense of self-care and towards positive changes. It is also worth highlighting the recognition of the importance of social exchanges in effecting these changes. Although with different emphases, the results point to the occurrence of advances in the participants’ self-knowledge, with practical consequences in 90% of cases. We conclude that, in the COVID-19 pandemic situation, internet-mediated research can achieve goals beyond data collection, generating positive effects on participants lives."

Published: May 2021

"This theoretical study is part of a doctoral thesis and aims to investigate how the psychoanalytic thinking of Hélio Pellegrino - the Brazilian psychoanalyst, poet and writer - is structured and its ethical and political implications in the formation of psychoanalysis. We note the importance of thematic research, since there is no scientific publication that has as its object of study a systematic analysis of the author's psychoanalytic production. Furthermore, investigations of this kind contribute to the establishment of a reference bibliography on psychoanalysis in Brazil. That said, this research was developed and completed through a study of a large part of his psychoanalytic production, which is under the custody of the personal archives of the Museum of Brazilian Literature, at the Casa Rui Barbosa Foundation (FCRB). In this work, we outline some elements of the analysis found in his work, whose focus is on reflecting on the epistemological, conceptual and practical foundations of psychoanalytic theory. It has, as a constant concern, the analysis of the problems that structure Brazilian society, observed through his own reading of the Oedipus complex, the constitution of subjectivity and the social pact, in general, and in Brazil, in particular. As such, he discusses the explicit commitment of psychoanalysis in transforming the serious social problems faced by Brazil, which are related to the serious structural problems of international capitalism, and which are also reflected in the problems of the development of psychoanalytic institutions around the world."

"Social advertisements with threat appeals are widely used to reduce drunk driving. However, research on the effectiveness of such advertising is limited. This study aimed to evaluate, what emotions cause threat appeal ads targeting drunk driving and whether these ads change risky driving attitudes. 41 students (17.1 percent males; mean age 20.9 years; 53.7 percent had a driving license) voluntarily participated in the experimental study. Every participant was randomly assigned to one of three groups: two experimental (watched one of two TV ads with threat appeals) or control group (watched car wash ad with no threatening stimuli). After watching one of three ads, all participants were asked to evaluate seven emotions and to fill in Driving Attitude Questionnaire (DAQ). Results revealed that both road safety threat appeal ads targeting drunk driving did not arouse any stronger fear emotions or differences in driving attitudes compared to control group. Both experimental groups didn’t differ in emotions or attitudes as well. No difference in emotions and attitudes was found when comparing the reaction of participants who have seen the specific ad before the experiment and those who haven’t. The fact of being a licensed driver was also not related to the level of reported emotions or attitude differences in both experimental groups. The study results reveal that the possible effectiveness of threat appeal ads from ongoing social marketing campaigns on reducing drunk driving is questionable and further studies are needed."

"Staying at the peak of professional success in medical is possible only for a doctor who is characterized by psychological health. The human life-world stability is contributed to success of the life self-fulfillment and transference of abilities inherent in him (human) into reality. The study sample is represented by 354 future doctors. Of these, 154 future doctors were characterized by psychological health. Qualitative analysis showed that future doctors who are characterized by psychological health are more inclined to analyze their own life deficits “here and now”. Often, such an analysis culminated in the realization of the possibility of approaching problems and difficulties, finding a different meaning. Usually assessed as “negative” or “stressful” events during the analysis were reformatted as events of a new experience. They are the basis for expanding the behavioral repertoire. It has been established that a high degree of human life-world stability and its constructive nature are the psychological conditions for the optimal combination of processes to achievement consistently high performances and maintain psychological health by future doctors."
"EFFECT OF MINDFULNESS MEDITATION AND COPING STRATEGIES ON AFFECT AND DEPRESSION SYMPTOMATOLOGY AMONG MEDICAL STUDENTS DURING NATIONAL LOCKDOWN - A PROSPECTIVE, NON-RANDOMISED CONTROLLED TRIAL "
Authors:   Faculty of Medicine, Imperial College London (UK), Khan-White Thomas
Published: May 2021

"This prospective, non-randomised controlled trial aimed to investigate the effects of brief app-based sessions of mindfulness meditation (MM) and utilisation of either problem-focused (PFC) or emotion-focused coping (EFC) styles on positive affect (PA), negative affect (NA) and depression symptomatology during nationwide lockdown due to coronavirus disease 2019 (COVID-19). This study enrolled 19 medical students to undergo a 10-minute MM intervention. These same students were also divided into either PFC or EFC groups. Affect was measured using the positive and negative affect schedule (PANAS), depression symptomatology was measured using the centre for epidemiological studies-depression (CES-D) scale and the brief COPE survey was used to categorise individuals as either PFC or EFC. Analysis showed no significant between-subject interaction for MM on PA, NA or CES-D score. Analysis of coping styles showed no significant between-subject interactions in relation to PA or NA, though CES-D scores approached significance (p=0.057) and PFC scored significantly lower than EFC at baseline (p=0.02). Significant within-subject effect of time found for PA and NA across both analyses (p<0.05). 61.1% of cohort scored above CES-D cut-off for being considered at risk of depression. These results identify a need for further work into more intensive MM interventions with larger sample sizes as well as study into stressors associated with lockdown to more fully establish whether PFC strategies are the most beneficial. In addition, a clearly high level of psychological distress has been implicated in this study population, which may have implications for student pastoral care during this period."

"Objective: The goal of this research was to revise Litman’s Epistemic Curiosity Scale (ECS), so that it can be applied to the evaluation of the developmental characteristics among Chinese senior high school students. Methods: 25 senior high school students were first invited to a trial test for confirming the item comprehensibility, after then 602 senior high students were enrolled to the formal testing for the item analysis and exploratory factor analysis. And 533 Chinese high school students responding ECS were submitted to test the construct validity of the localized Chinese-version ECS. Then the scale was applied to 366 subjects to test the internal consistency indices and criteria correlation validity. Finally, 153 senior high school students were used to test test-retest reliability of the ECS. Results: All of the 10 items were retained, through exploratory factor analysis and confirmatory factor analysis, the two-factor model which was consistent with the original scale proved to be the most appropriate, its main goodness of fit indices were: x2/df=2.68, CFI=0.93, NFI=0.93, TLI=0.90, GFI=0.97, AGFI=0.95, and RMSEA=0.06. The study found internal consistency indices (Cronbach’s alpha) from 0.73 to 0.78 in the first three samples. In addition, the ECS had a high correlation with Chinese version of Trait Curiosity Scale (r=0.53, p<0.001), test-retest reliability over 2-month interval was 0.54 to 0.56 for each of the 2 sub-scale and 0.64 for the total ECS. Conclusion: Findings in these studies support the cross-cultural validity of the ECS in Chinese senior high school students."
PERSONAL AND ORGANIZATIONAL CHARACTERISTICS ANTECEDENTS OF MEANINGFUL WORK
Authors:   Department of Human Sciences, University of Verona (Italy), Tommasi Francesco , Ceschi Andrea , Sartori Riccardo
Published: May 2021

"The contribution presents evidence of the role played by personal and organizational characteristics of employees in the experience of meaningful work. As referred to the individuals’ experience of value and significance of their work, meaningful work is a critical working phenomenon both for individuals (e.g., individuals’ well-being) and organizations (e.g., workers’ productivity). Therefore, a large number of studies have tried to understand its antecedents, however, it is still not clear about how and to what extent personal and organizational characteristics are associated with meaningful work. For instance, it is unclear the roles of a higher level of education as well as financial returns or good working conditions (e.g., high level of salary and good health insurance) for the pursuit of meaningful work. The contribution considers such a need for knowledge and aims to understand the antecedent role of personal and organizational characteristics in the experience of meaningful work. 570 Italian employees participated in a cross-sectional study that comprised measures of meaningful work and related facets, as well as questions on personal and organizational characteristics. Data were analyzed via the MANOVAs and results showed significant associations with meaningful work dimensions and personal characteristics, such as education, social class and health as well as organizational characteristics, such as job contract, job sector and salary."

"Various psychological reactions, found to traumatic distress, are widely known in psychological literature. Based on 30-years theoretical and empirical studies of extreme human experience, we suggested unconventional approach to differentiation of psychological reactions and human behavior in various extreme events into three groups:1) distress, disorganization, disorders, traumatization; 2) adaptation, hardiness, resilience; 3) personal growth, transgression (Magomed-Eminov M., 1998, 2007). The proposed research is devoted to the positive psychological consequences of COVID-19 disease. Our aim was to study the positive psychological influence of COVID-19 disease for lifestyle, behavior, communication, life relationships, and well-being of people, who were ill. We suggested and checked the hypothesis, that objectively serious COVID-19 disease, carrying uncertainty, confusion, horror, for many people discover also a heroism, pride, the experience of success because of coping with disease. We collected the narratives of people, who got COVID-19, and conducted content analysis. Our study showed that after being ill COVID-19 interviewed people discovered new meanings of existence, despite the loss of loved ones, socio-economic difficulties and other hardships of COVID- 19 pandemics. We conclude that COVID-19 disease as extreme situation not only becomes a test, but can also open up new perspectives, value of other people and of life in general."

"The study of the ability of self-awareness (self-awareness, the ability to perceive one's own body and mental properties separately from objects of the external world) in animals contributes to the study of the specifics of human consciousness. One of the aspects of self-awareness is body-awareness, which is expressed in the ability of an animal to take into account the physical parameters of its body when regulating behavior. We studied the ability of ferrets (Mustela putorius furo) to be aware of the limits of their own bodies. To solve the experimental problem, the animals had to choose holes suitable in size for penetration in the partition that divided the sections of the experimental setup. The shapes and sizes of the holes varied. We have used both small area holes that are suitable for penetration and large areas that are not suitable for penetration. It was found that all 6 animals participating in the experiment were able to choose a hole suitable for penetration from the first trial, despite the fact that it was smaller than the unsuitable one in area. In 18 test trials, ferrets made 105 successful penetrations and 3 unsuccessful attempts. This distribution differs from the uniform one (?2 = 97.25; df = 2; p <0.01). None of the individuals showed a significant reduction or increase in unsuccessful attempts to penetrate the holes This data may indicate that ferrets have knowledge of the boundaries of their bodies and the ability to compare them with the parameters of the penetration hole."

THEORETICAL ANALYSIS OF SEMI-ACTIVE NOISE CONTROL
Authors: Kletschowski Thomas
Published: May 2021

significant reduction of disturbing noise can be achieved by passive, semi-active and fully active control approaches.
Passive noise treatments such as dynamic vibration absorber are very robust and can be applied to obtain a broadband performance.
Active noise control systems are designed to control harmonic or broadband noise. They are very effective, if the control volume is
small as known from single-input/single-output systems used in active headphones. However, if distributed control is required, the
control profit is not scalable, because the required multiple-input/multiple output systems must be adjusted to specific acoustic modes
as known from the active control of propeller-aircraft interior noise. Semi-active control that is based on the principle of dissipation
allows to combine several single-input/single-output systems without coupling. Thus semi-active approaches are capable to solve
the problem of scalability. The present paper reports on a specific approach that is based on a dynamic absorber attached to a vibrating
structure and coupled with a dissipating electrical network. The electrical components of this network can be adjusted to the
mechanical impedance to realize dissipation. To focus on the performance principle, the theoretical investigations are presented in a
dimensionless analysis.

grinding. The volume of grinding operations is from 25 to 60 % of various technological operations. Working conditions in the grinding
areas are considered harmful and dangerous. [1]. The noise levels at the workplaces of these machines’ operators exceed the standard
values. The sound emission from the part during grinding is a particular feature of this process. A theoretical study of the noise generation
processes on such machines was carried out to develop the recommendations.

EXPERIMENTAL RESEARCH OF ENVIRONMENTAL NOISE IN URBAN CONDITIONS BEFORE AND DURING COVID-19 PERIOD ON THE EXAMPLE OF SAMARA REGION OF RUSSIAN FEDERATION
Authors: Vasilyev Andrey
Published: May 2021

Today the acoustical pollution is well monitored, especially in the urban environment, and in particular area it is still increasing.
Environmental noise impact is increasing every year and may cause serious negative problems for inhabitants. Transport
and industrial plants are making the most significant noise levels in the city environment. This paper presents the results of research
of environmental noise in urban conditions before and during COVID-19 period on the example of Samara region of Russia. In Russia
strong COVID-19 restrictions of traffic movement and industrial enterprises operation have caused significant variations of environmental
noise generation and impact in conditions of urban territories. Comparison of results of environmental noise measurements
noise in urban conditions before and during COVID-19 period is showing that transport noise level is reduced, but the industrial noise
level is almost the same, especially in low frequency range.

Published: May 2021

In the present study, an approach has been tested for assessing and mapping the risk levels caused by the impact of the
noise factor in urban development on the example of urbanized areas of a large city. The approach is based on an acoustic modeling
algorithm associated with work in geographic information systems (hereinafter referred to as GIS) for the tasks of hygienic regulation
and health risk assessment of the population living in dense urban areas. The paper describes the identification and integration of a
set of initial data on the noise factor of exposure with the subsequent construction of a computational model. The results obtained are
supplemented with methodological approaches to assess the health risk of the population from the impact of traffic noise in accordance
with the approved methodological recommendations for the impact of this factor.
Risk levels are calculated without changes in the urban planning situation in the study area with the duration of residence of the exposed
population of 20, 30, 40 years. In addition, predictive calculations of changes in risk levels for a period of 20, 30, 40 years in the
context of a construction project were performed. Risk calculations were carried out at 49210 calculated points located in 38 planes,
including at a height of 1.5 m at the level of human breathing in the area of residential buildings, corresponding to each computational
grid, to build a volumetric (3D) model. The volumetric model is built to assess the living conditions of the exposed population,
depending on the floor of residence. A moderate risk before the implementation of a construction project is formed up to a maximum
of 13, 21, 23 meters in living conditions for 20, 30, 40 years, respectively, while after the implementation of the project, a moderate risk
reaches a maximum height of 21, 39, 51 meters in conditions of a similar exposure duration (20, 30, 40 years old). A high risk in both
cases is observed at a height of 1.5 - 3 meters above ground level only during 40 years of living in the area of this exposure, which is due
to the previously close located highways. Thus, under dense urban development, it is optimal to live on the middle floors (7-8 floors)
and above, in conditions of chronic exposure to the noise factor.

Comparing the noise characteristics of natural draft counterflow cooling towers during their operation with dry cooling towers at the same cooling capacity carried out. The difference in the reasons for the noise generation of natural draft counterflow
cooling towers in comparison with dry cooling towers showed. A condition obtained for the pressure of axial fans for octave bands and for the sound level in dBA, when dry cooling towers emit sound energy more than natural draft cooling tower. It shows that dry cooling towers are noisier than natural draft cooling towers for the same cooling capacity.
COVID-19 AND SOUNDSCAPE CHANGES DUE TO THE LOCKDOWN. THE CASE OF LIMA, PERU
Authors: Montano walter , Gushiken Elena
Published: May 2021

The COVID-19 pandemic has changed the way of life of the world’s population, and initially all non-essential commercial and industrial activities in all countries were suspended, as well as the temporary closure of major airports and educational activities. As never before, environmental sound levels were reduced as a result of the quarantine, as the authorities ordered people to remain confined in their homes in order to reduce and prevent the SARS-CoV-2 transmission. Cities became silent and in some cases birds and wildlife “took over” this situation. This change in the soundscape led to sounds that were previously masked, now being heard, i.e. HVAC and other noises. This article presents the case of Lima, Peru, in which the impact and annoyance produced by aircrafts overflights are analyzed (during 2020); as well as the healthy soundscape levels achieved ‘thanks’ to the commercial lockdown and leisure activities.

Published: May 2021

Як свідчить аналіз літературних джерел та узагальнення результатів наших дослі- джень [1-14], розвиток текстильної нанонауки у галузі текстильного матеріалознавства та това- рознавства за останні роки виявився актуальним і значимим не тільки для розвитку галузевої науки, але і відповідних навчальних дисциплін в університетах сфери легкої промисловості та торгівлі України. В даній роботі ми обмежилися розглядом тільки ключових товарознавчих аспектів роз- витку текстильного товарознавства нанотекстилю й одягу України. Необхідність вирішення цих проблем диктувалася низкою причин, а саме: постійним зростанням обсягів виробництва та роз- ширення асортименту нанотекстилю й одягу різного цільового призначення у світі та зростанням їх імпорту в Україну; обмеженістю товарознавчих досліджень нанотекстилю й одягу в універси- тетах сфери легкої промисловості та торгівлі України; потребою створення теоретико-мето- дологічних засад розвитку в Україні товарознавства нанотекстилю і наноодягу як нових перспек- тивних галузей нанонауки, як це прийнято в США, Японії, Китаї та інших економічно розвинутих країнах світу; обґрунтуванням доцільності розвитку товарознавства нанотекстилю і наноодягу як нових профілюючих дисциплін на товарознавчо-комерційних факультетах університетів сфери легкої промисловості та торгівлі України; потребою подальшого вдосконалення методики тесту- вань нанотекстилю і наноодягу як нових товарів на сучасному товарному ринку України. Обґрунто- вано доцільність подальшого вдосконалення системи підготовки фахівців технологічного і товароз- навчо-комерційного профілю для потреб легкої промисловості і торгівлі України. Одним із шляхів вирішення цього завдання є написання нових підручників і навчальних посібників із нових дисциплін (нанонауки та технологій нанотекстилю і товарознавства наноодягу). Обґрунтовано доцільність написання нових підручників із товарознавства нанотекстилю і наноодягу для університетів легкої промисловості та торгівлі, які забезпечать підготовку фахівців технологічного і товарознавчо- комерційного профілю.
