Authors: Nikolova Mima , Kyuchukova Silviya , Andonova Albena 
Published: November 2021

Bulgaria is the second-fastest aging nation in Eastern Europe and fifth in the world. Older people are the largest and ever-growing group of people in health care. The most common diseases in this age group are circulatory, endocrine, digestive, musculature, neoplasms, and respiratory systems. Some of the main reasons for these diseases include an unhealthy diet, a sedentary lifestyle, and obesity.
One hundred twelve adult patients with chronic diseases were interviewed.
The aim of the study is to establish the awareness of older people about overweight-related problems. In order to increase their knowledge and improve their quality of life and independence, we prepared a training program (Table4).

Authors: Šniepienė Gražina , Jankauskienė Rita 
Published: November 2021

Background. The researchers have shown that even small doses of some chemical substances in cosmetics, when absorbing and accumulating in the body, can damage the skin and provoke various diseases. Therefore, the choice of organic cosmetics with certified ingredients can contribute to human health and nature conservation.
The survey aimed to determine behavior of choice and consumption of organic cosmetic products according to the consumers’ socio-demographic characteristics.
Methods. A quantitative survey was performed, a validated questionnaire and data collection method – a written survey were used. Survey sample – 335 people (38.5 ± 4.07 years old). Data analysis using SPSS 26.0 was performed, calculated percentage frequencies, mean, Pearson’s Chi-Square test to detect statistically significant differences, and Spearman’s correlation was used.
Results. The study found that more than half of women used organic cosmetics. A significant difference (p <0.05) was found with age, which showed that organic products were used significantly more often by 26–35-year-old individuals and between the sexes (p = 0.05). It was found that facial skincare, body care, and hair care products are the most commonly used, while pregnancy skincare products are the least commonly used. Consumers indicated the reasons for choosing these products: health benefits, natural composition, non-polluting environment during production, and recyclability of packaging. Most often, respondents do not use such cosmetics due to unclear labeling and the higher prices of these products. Sufficient and complete information on the label, a reliable and well-known producer are considered to be the most important identification criteria. In contrast, a special point of sale, clear and attractive promotional/visual information being the least important.
AN APPROACH FOR DEVELOPMENT AND APPLICATION OF CPSS- EDUCATIONAL ENVIRONMENTS IN BULGARIAN SCHOOL

Published: November 2021

Modern realities in the era of Industry 4.0 and the global Covid-19 pandemic place new challenges to education. It is a fact that classical learning, supported by modern information and communication technologies, provides an effective learning process, but the Covid-19 realities require a rapid transition to distance absentee learning. The use of computer-based training systems and cloud platforms has its advantages, but also problems related to the low level of personalization of the learning process and the adaptability of the learning content to the specific characteristics of each student.
Cyber-physical and social systems (CPSS) largely solve the problems associated with integrating processes and interactions in the virtual world with the dynamically changing conditions of the physical world in which learning occurs. This gives grounds to draw the attention of specialists to the creation of CPSS educational platforms for secondary school. Following this approach, we created a prototype of ь CPSS educational space called BLISS. The results of the test application of this platform in the school environment give us reason to believe that if we put the learner with his/her peculiarities, goals, and interests at the center of such a system, and present him/her in the virtual space through his / her personal assistant, we could significantly increase the interactivity of the learning process and the adaptability of the offered learning content.

Authors: Blumberga Solveiga , Lapkovska Laura 
Published: November 2021

The COVID-19 pandemic has altered the majority of the world’s organisations through making remote work a part and parcel of everyday life. The number of people working remotely has increased substantially creating a challenge for the organisations to manage and involve their personnel. Engagement and involvement of the personnel are major factors contributing to a positive outcome of the remote work processes. The aim of this research paper is to establish what the engagement and involvement of the personnel are while practising remote work in the Latvian financial institutions. This research paper put forward the following issues for exploration: what is the engagement of the financial institutions’ personnel in their work while working remotely? What is the involvement of the financial institutions’ personnel in their work while working remotely? Is there a link between engagement and involvement of the financial institutions’ personnel during remote work? This paper explores the definitions of engagement and involvement by various authors and many forms of remote work putting emphasis on expansion of remote work due to the pandemic. The research made use of 3 surveys: a survey on the engagement of personnel during remote work, a survey on involvement of the personnel during remote work and a survey on the personnel’s opinion on remote work compiled by the authors of this research paper. There were 98 full-time employees of financial institutions participating in the research who were transferred from office jobs to a form of remote work during the COVID-19 pandemic. The results of the research demonstrate that only a fraction of the financial institutions’ personnel were engaged and involved during their remote work and that institutions had to resort to additional measures in order to promote involvement and engagement of the rest of the personnel and attain better operational results. The major problems highlighted by the results of the research are: insufficient internal information exchange and co-operation. The personnel feel responsible for the performance of their work, but admit to lacking inspiration that would foster their engagement. They also acquired negative experiences while working remotely. The results of the research identify a need for further research on the significance of the internal culture and communication of financial organisations for the promotion of involvement and engagement of personnel during remote work.
PUBLIC PERCEPTION OF THE CONSEQUENCES OF POVERTY IN SELECTED LIFE DIMENSIONS
Authors: Kovalčíková Nadežda , Bánovčinová Andrea 
Published: November 2021

Poverty is a phenomenon that receives a lot of attention from a wide range of professionals as well as the lay public. This is a serious problem that significantly changes the lives and functions of individuals, families, as well as communities.
The aim of this study was to find out how society perceives the consequences of poverty in individual dimensions of human life selected by us and also to find differences in perception of the consequences of poverty in terms of the selected demographic data (gender, place where the respondent lives, place of residence – city or countryside, faith, employment status, shared household, benefits in material deprivation, and an opinion on who should primarily address the problem of poverty). A quantitative research strategy was implemented using a self-designed questionnaire. The questionnaire contained 37 items and focused on the perception of poverty and its consequences in our selected areas. The questionnaire contained 6 basic dimensions, resp. areas. These were the health area, the hygiene area, the social area, the psychological area, the structural area and the housing area. We used a deliberate and quota selection (region, gender). The total sample (n) consisted of 384 respondents. The average age of the respondents was 36.30 ± 12.91 years old (min. 18, max. 75).
The results did not show a statistically significant difference in the perception of areas most affected by poverty in terms of gender; in terms of receiving benefits in material need, there was a statistically significant difference in health, mental health, housing and social affairs. In terms of residence (countryside, city), a statistical difference was recorded only in the area of ​​health. There were also significant statistical differences in the area of geography (the region in which the respondent lives), in the area of health and hygiene, and the structural area. The practice of faith has proven to be an important determinant of the perception of poverty, especially in the social and psychological spheres. We also noticed differences in the perception of poverty in some areas in terms of shared household and employment status.
IN-SERVICE TEACHERS' VIEWS ON DEVELOPING COMMUNICATIVE COMPETENCE AT PRIMARY LEVEL IN THE PROCESS OF TEFL IN SLOVAKIA
Authors: Paulikova Klaudia 
Published: November 2021

Reaching communicative competence in a foreign language is one of the key objectives of the foreign language education policy of multiple European countries, including Slovakia. The unified concept of communicative competence provides learners with equal opportunities for mastering languages at their best and enables its development from the very beginning of learners' studies. In low proficiency levels (A1) in primary education teachers play a crucial role in developing communicative competence of their learners. Research in the field reveals that although teachers are aware of their great influence and importance in the development of communicative competence, they often do not provide sufficient circumstances for learners to reaching it. A qualitative inquiry conducted with a number of in-practice English teachers working in Slovak primary schools presents the importance of having balanced development in all the components of communicative competence in TEFL, its implementation into the lessons of English, as well as an overall view of teachers’ standpoints towards its development at the primary level. The results show the tendencies of teachers to concentrate more on certain (especially linguistic) elements of communicative competence, whereas other competences (mainly of pragmatic character) are often neglected.

Published: November 2021

Unmanned Surface Vehicles (USV) are self-driving vehicles that operate on the water surface. In order to be operated autonomously, USV has a guidance system designed for path planning to reach its destination. The ability to detect obstacles in its paths is one of the important factors to plan a new path in order to avoid obstacles and reach its destination optimally. This research designed an obstacle tracking system which integrates USV perception sensors such as camera and Light Detection and Ranging (LiDaR) to gain information of the obstacle’s relative position in the surrounding environment to the ship. To improve the relative position estimation of the obstacles to the ship, Kalman filter is applied to reduce the measurements noises. The results of the system design are simulated using MATLAB software so that results can be analyzed to see the performance of the system design. Results obtained using the Kalman filter show 12% noise reduction. Keywords: filter kalman, obstacle tracking, unmanned surface vehicle.

Published: November 2021

Aims Varus-valgus constrained (VVC) devices are typically used in revision settings, often with stems to mitigate the risk of aseptic loosening. However, in at least one system, the VVC insert is compatible with the primary posterior-stabilized (PS) femoral component, which may be an option in complex primary situations. We sought to determine the implant survivorship, radiological and clinical outcomes, and complications when this VVC insert was coupled with a PS femur without stems in complex primary total knee arthroplasties (TKAs). Methods Through our institution’s total joint registry, we identified 113 primary TKAs (103 patients) performed between 2007 and 2017 in which a VVC insert was coupled with a standard cemented PS femur without stems. Mean age was 68 years (SD 10), mean BMI was 32 kg/m2 (SD 7), and 59 patients (50%) were male. Mean follow-up was four years (2 to 10). Results The five-year survivorship free from aseptic loosening was 100%. The five-year survivorship free from any revision was 99%, with the only revision performed for infection. The five-year survivorship free from reoperation was 93%. The most common reoperation was treatment for infection (n = 4; 4%), followed by manipulation under anaesthesia (MUA; n = 2; 2%). Survivorship free from any complication at five years was 90%, with superficial wound infection as the most frequent (n = 4; 4%). At most recent follow-up, two TKAs had non-progressive radiolucent lines about both the tibial and femoral components. Knee Society Scores improved from 53 preoperatively to 88 at latest follow-up (p < 0.001). Conclusion For complex primary TKA in occasional situations, coupling a VVC insert with a standard PS femur without stems proved reliable and durable at five years. Longer-term follow-up is required before recommending this technique more broadly. Cite this article: Bone Jt Open 2021;2(11):921–925.

Published: November 2021

To improve the depth accuracy of an indirect time-of-flight CMOS image sensor, high modulation frequency is often adopted. It will result in high power consumption of an on-chip demodulation driver, and this problem will be much more serious when the resolution of the sensor is much higher. In this paper, a power reduction method that can lower the power consumption of the demodulation driver circuit during the integration time while obtaining accurate high-resolution depth maps is proposed and analyzed theoretically. The method decreases the number of driven pixels at a high-modulation frequency by a programmable resolution adjustment circuit to obtain an accurate low-resolution depth map. A low-depth accuracy high-resolution depth map is obtained at a low modulation frequency, and then a modified super-resolution algorithm is used to obtain an accurate high resolution solution depth map. To demonstrate the effectiveness of the proposed method, a model is established based on the actual indirect time-of-flight sensor architecture, then the depth error and power consumption are analyzed by the simulation results of the model. In the simulation, 25 MHz and 100 MHz are used as the low modulation frequency and high modulation frequency, respectively. With the best scenario in depth accuracy kept, average power consumption decreases 38.47% and peak power consumption decreases 49.83% while the depth error that is represented by RMSE merely increases 8.08%.

Published: November 2021

An enhanced self-mixing interference (SMI) method in a laser diode (LD) based on a Fabry–Perot etalon (FPE) is presented. This method uses uncoated fused silica to form a FPE as a narrowband filter in the LD outer cavity, which can tune the laser wavelength to the edge of the FPE transmission spectrum profile to perform intensity demodulation. We compare the SMI signal based on the FPE filter with the conventional SMI signal. The experimental results show that the amplitude of the SMI signal based on the FPE filter is enhanced about 5 times in the range of 1 µm–5 µm; the displacement reconstruction errors are reduced by 30 nm; and the signal quality is significantly improved.

Introduction
A healthy and balanced diet is very important during pregnancy. By enhancing maternal nutritional status, healthcare providers can lower the risks of pregnancy complications and adverse birth outcomes.

Objectives
To assess the pre-natal nutrition knowledge and services rendered by healthcare providers in antenatal clinics at Primary Health care Centres in Lagos, Nigeria.

Methodology
This was a cross-sectional study carried out in June—September 2019. Self-administered questionnaires were used to collect data on nutritional knowledge from 391 nurses and midwives who provided pre-natal nutrition education. Direct observation with checklist was used to assess the nutrition education services at the ANC clinics and covered: adequacy of the venue, availability/use of nutrition education resources, education content and teaching strategies. EPi-Info version 3.5 was used for data analysis. Inferential statistics such as chi square and multiple logistic regression were used to determine associated factors and predictors of nutrition knowledge. The level of significance was set at 5% (p<0.05).

Results
The mean age of respondents was 41.71±10.33years, all were females; 44.8% were Registered Nurses, 12.0% were Registered Midwives, and 23.8% had a B.Sc. in Nursing. Majority (81.3%) had taken a nutrition course in nursing training program, 62.1% as elective classes. Majority (81.1%) had good knowledge of prenatal nutrition. Respondents who were older (51-60years) (p<0.001), single (p<0.001) and Christian (p = 0.001) had significantly better knowledge. Nurses who had University degrees (p<0.001), of higher cadre (p<0.001), more years of practice (p<0.001) and involved in treating severely malnourished children (p = 0.013) were also significantly more knowledgeable. Respondents below 40 years (OR 0.104, CI 0.049–0.218) and those with 10 years or less of practice (OR 0.189, CI 0.092–0.387) had less odds of having good nutrition knowledge. Being single (OR 8.791, CI 3.125–24.731), and Christian (OR = 5.810, CI: 3.321–10.164) predict good nutrition knowledge. In 39% of the 41 PHCs observed, quality of nutrition education services was inadequate. Gaps were mainly in availability of certain nutrition education facilities/resources and teaching strategies.

Conclusion
The majority of the respondents had good knowledge of pre-natal nutrition. Overall, however, nutrition education services provided by two-fifths of the facilities were inadequate. Interventions to improve prenatal nutrition knowledge of nurses/midwives should be focused more on those who are younger and have less work experience. All necessary equipment required for health service providers to execute their roles as nutrition counselors and educators should also be provided by the government.

Zusammenfassung
Die Pflege befindet sich nicht erst seit der COVID-19-Pandemie in einer (Personal-)Krise, vielmehr wirkt diese wie ein Brennglas, das den Personalmangel in der Pflege noch weiter verschärft und das bisherige Ausmaß für eine breite Öffentlichkeit sichtbar macht. Im Zuge der Krisenbewältigung wird den Leitungspersonen der Einrichtungen pflegerischer Versorgung eine hohe Bedeutung als Krisenmanager*innen zugeschrieben, auch wenn diese oftmals nur als Krisenverwalter*innen agieren können: Die Handlungsintensität des Managements ist hoch, dennoch scheinen die eingesetzten Personalgewinnungsmaßnahmen nicht branchenweit zu greifen. In unserem Beitrag beziehen wir uns zur theoretischen Einordnung auf das Konzept der Risikopolitik. Anhand empirischer Daten des Verbundprojekts ZAFH care4care zeigen wir auf, wie Führungshandeln im Krisenmodus stattfindet, welche Widersprüche damit einhergehen und wie die eingesetzten Maßnahmen die vorhandene Problematik verschärfen.
A Digital Revolution? Insiders, Outsiders, and the “Disruptive Potential” of Instapoetry
Authors: Miller Alyson 
Published: November 2021

Abstract
Whilst frequently dismissed as “cliché, banal, derivative, portentous, repetitive, and manipulative” (Hodgkinson), offering little other than “fidget-spinner” distractions to appease the masses (Roberts), Instapoetry is a slippery, intricate mode. The simplicity of its aesthetic belies its complex political manoeuvrings, marked by an imperative towards a progressive ideology that contests the sexism and racism of dominant culture. Indeed, despite its “byte-sized” accessibility (Bresge), Instapoetry is deceptive, evoking discourses of ‘outsiderness’ that locate the genre within an often-problematic logic of rebellion. Examining black feminist Instapoets such as Aja Monet, Yrsa Daley-Ward, and Nayyirah Waheed, as well as ‘superstars’ of the genre, including Rupi Kaur, Atticus, and Nikita Gill, this paper argues that there is a persistent disjuncture between the extra-textual commentary surrounding Instapoetry, particularly by way of interviews and artistic statements, and the content of works which repeatedly reinscribe conservative, patriarchal, and heteronormative worldviews. Whilst the pithy convenience of new media poetries has undoubtedly helped magnify oppressed voices and perspectives, it has also, more cynically, fostered an insistence on universality that erases complexity and difference in the (largely aesthetic) interests of harmony, and the appeasement of both dominant and minority cultures.
