Authors: Nogueira Mª Nilza , Silva Joana , Nogueira Isabel , Pacheco Maria Neto , Lopes Joana , Araújo Fátima 
Published: May 2022

Background
Prevention of falls among older adults has boosted the development of technological solutions, requiring testing in clinical contexts and robust studies that need prior validation of procedures and data collection tools.

Objective
The objectives of our study were to test the data collection procedure, train the team, and test the usability of the FallSensing Games app by older adults in a community setting.

Methods
This study was conducted as a pretest of a future pilot study. Older adults were recruited in a day care center, and several tests were applied. Physical exercise sessions were held using the interactive FallSensing Games app. Nurse training strategies was completed.

Results
A total of 11 older adults participated. The mean age was 75.08 (SD 3.80) years, mostly female (10/11, 91%) and with low (3-6 years) schooling (10/11, 91%). Clinically, the results show a group of older adults with comorbidities. Cognitive evaluation of the participants through the Mini Mental State Examination showed results with an average score of 25.64 (SD 3.5). Functional capacity assessed using the Lawton Instrumental Activities of Daily Living Scale (overall score from 0-23, with lower scores reflecting worse capacity to perform activities) showed impairment in different instrumental activities of daily living (average score 14.27). The data collection tool proved to enable easy interpretation; however, its structure needed small adjustments to facilitate the data collection process. Despite the length of the questionnaire, its implementation took an average of 21 minutes. For the assessment of the prevalence of fear of falling, the need to add a question was identified. The performance of functional tests under the guidance and presence of rehabilitation nurses ensured the safety of the participants. The interactive games were well accepted by the participants, and the physical exercises allowed data collection on the functionality of the older adults, such as the number of repetitions in the tests, range of movement (angle), duration of the movements, and execution of each cycle. Concerning the training of the nurses, it was crucial that they had experience with the platform, specifically the position of the chair facing the platform, the position of the feet, the posture of participants, and the use of sensors.

Conclusions
In the future pilot study, the researchers point out the need to design a study with mixed methods (quantitative and qualitative), thus enriching the study results.
Lithic economy in South Western France during the Neolithic: A case study from a coastal site - La Lède du Gurp (Aquitaine)
Authors: SOLANAS Sofia 
Published: May 2022

The prehistory of South-western France is known worldwide for its rich record of Palaeolithic sites, especially from the Dordogne region. However, while research on the Palaeolithic is extremely prolific, the Neolithic was at the same time relegated to the background. Since the beginning of the discipline, few researchers worked on the Neolithic from SW France. Besides, they focused on ceramic typological analyses to describe cultural groups, rarely considered lithic tools and armatures, and never performed any techno-economical study of lithic productions. For over thirty years, rescue archaeology excavations revealed a large presence of Neolithic sites for this period; nonetheless Neolithic research remains little developed in relation to its potential. As part of my PhD thesis, the aim will be to fill this gap by characterizing lithic productions through techno-economical analyses, in order to describe the cultural groups existing in Northern Aquitania during the 4th and the 3rd millennia. With the example of La Lède du Gurp, a littoral occupation site dated to the middle and recent Neolithic, I will try to highlight in this paper what the study of lithic industries can say about a cultural group at a local scale.
The reconstitution of the operating chains and the statistical analysis of small assemblages of non-standardised lithic reduction, allowed us to highlight a similar low investment in lithic production between the Middle and the Recent Neolithic of La Lède du Gurp. Our approach has enabled us to observe that a low investment in lithic production may reflect the complexity of the Neolithic groups and the complementarity of lithic industry with other technical subsystems directly related with the group's natural environment, as may it be the case for salt production during Recent Neolithic at La Lède du Gurp.
Do international remittances promote poverty alleviation? Evidence from low- and middle-income countries
Authors: Saptono Prianto Budi , Mahmud Gustofan , Lei Li-Fen 
Published: May 2022

Abstract
Unlike previous empirical studies, this paper investigates the contemporaneous and lagged impacts of international remittances on poverty alleviation using data for 65 low- and- middle-income countries from 2002 to 2016. By using two-stage least square (2SLS) regression analysis, this study establishes that, in general, international remittances per gross domestic product (GDP) significantly mitigate poverty. On average, a 10-percentage-point increase in remittances will lead to a similar decrease in the poverty headcount ratio at USD 1.90 a day, a 4.8-percentage-point decline in poverty gap ratio at USD 1.90 a day, and a 6.7-percentage-point reduction in the poverty gap ratio at USD 3.20 a day. This result remains robust with the inclusion of political factors in the model. Moreover, the system-generalized method of moments (SGMM) estimations found that the contemporaneous effects of international remittances are much more substantial than their lagged effects. This indicates that most of the poverty alleviation role of remittances is contributed by its direct effect on increasing the wealth index of recipient households rather than the spillover effect on other members of the community. Therefore, we strongly suggest that efforts be made to improve the remittance infrastructures, especially in recipient countries, and the development of cooperatives in the enclaves of migrant workers to spread the beneficial effects of remittances to all members of society.

Authors: Wahid Mahsun , Jamala Nurul 
Published: May 2022

Lighting is one of the important factors to recognize the environmental situation. Lighting is needed by humans, with good lighting we can visually recognize objects clearly. The suitability of lighting with recommended light standards and the arrangement of building facades in accordance with the distribution of lighting will have an impact on the visual quality of a building. Along with the development of technology and information, people's lifestyles are increasingly advanced and developing. Likewise, the function of artificial lighting, which used to only function as lighting at night, has now developed into an important part of the aesthetic forming factor of a building. So there is a need for a survey to see how big the difference in perception of the visual quality of lighting is by using floodlights on the Phinsi Tower. The survey method of data collection used quantitative and qualitative research methods. Mixed methods are divided into quantitative methods (research using questionnaires and SPSS data processing) and qualitative (respondent perception, interview and observation). Based on the results of surveys and tests conducted on 17 simulation models, different results were obtained in each test model. This explains that the use of floodlights greatly influences the visual quality of the Phinisi Tower facade. Of the 17 lighting simulation models that have been made, Model 17 has the highest average score of 5.08 and the lowest is Model 10 of 2.53 (a rating scale of 1 to 7).

Published: May 2022

One of the causes of defects in casting is due to poor gating system design. In conventional casting methods, the gating system design process is carried out by trial and error to find the best design results. Computer modeling and simulation offer process design in a much faster time, and at much less cost, compared to conventional methods. The gating system design approach with a combination of well calibrated simulation software can avoid defect before casting. Casting simulation helps to visualize the phenomena of filling, molten metal solidification, and shrinkage porosity. The resulting casting simulation can be displayed in graph variants at specific nodes with line graphs or numerical numbers manually. This study discusses the simulation of casting a flange reducer from aluminum alloy material using a resin sand mold. The initial dimensions of the gating system used are sprue of 14.5 x 8.4 x 180 mm, runner 147 x 10 x 5.5 mm, ingate 80 x 10 x 5.5 mm with a bottom gate channel system. Total of dominant porosity that occurs using the initial gating system is 65.31 % and show the undirectional solidificiation behavior. After modifying the gating system and increasing the riser size, the simulation results show directional solidification behavior starting from the thinnest part to the thickest part and ending at the riser. The shrinkage porosity can compensate with the total of porosity is 57.60 % at the riser . Modification of the channel system is required to obtain a sound casting or porosity free.
On Achieving Strategic Goals and Ensuring the Security of Modern Russia
Authors: Kazantsev S. V. 
Published: May 2022

The strategic objectives of the subject (a person, a group of individuals, an estate, a class, a nation, a community, a state, groups of states, a society) are determined mainly by the conditions in which the subject is located. It includes its specifications (including traditions, worldview, level of development, and available knowledge) by its capabilities and opportunities. Changing even one of the listed factors can cause a change in goals. The paper presents the results of a study of the movement towards achieving vital goals that society sets for the long term: society’s strategic goals. The goal of society in this study the author understood as a specific image (representation) of the result formed by society, which it strives to achieve. The author assessed the speed and nature of the movement towards achieving the constituent components of the strategic goals of the Russian Federation — preserving the nation and increasing the economic power of the country. Statistical data of the World Bank and the Federal State Statistics Service of the Russian Federation from 1992 to 2020 served as initial information for calculations. The calculations performed showed that the movement towards achieving the set goals was of an oscillatory nature, and the amplitude of fluctuations in time tended to decrease. The latter indicates a slowdown in the speed of approaching the set goals.
Abundance of Microplastics in Wastewater Treatment Sludge
Authors: Tang Kuok Ho Daniel 
Published: May 2022

Wastewater treatment plants (WWTPs) have been regarded as feasible interceptors of microplastics, which have now contaminated all spheres of the environment. The microplastics removed from WWTPs are frequently trapped in the sludge produced. This article aims to examine the abundance of microplastics in the sludge of WWTPs in different regions by reviewing the relevant scholarly papers published between 2016 to 2022. The papers were retrieved from three databases, namely Web of Science, Scopus, and ScienceDirect. WWTPs receive influents containing microplastics whose abundance differs significantly in relation to the population density, urbanization level, and land use of the areas served. Depending on the water treatment strategies and the efficiencies of the WWTPs, a large proportion of the microplastics in the influents is trapped in the sludge, giving a common sludge-to-influent abundance ratio of 0.02 to 0.77, though a ratio of 3.4 has been reported for recycled activated sludge. Sludge treatment affects the final abundance of microplastics therein. However, a relationship between the abundance of microplastics in influents and that in sludge cannot be established. The reutilization of sludge as fertilizer introduces microplastics back into the environment and significantly compromises the potential of WWTPs as interceptors and sinks of microplastics. This review calls for strategies and technologies to reduce, if not remove microplastics in the sludge of WWTPs. It suggests that future research could take this path to optimize the role of WWTPs as sinks of microplastics. Doi: 10.28991/HEF-2022-03-01-010 Full Text: PDF
Decision-making Improvement in Dynamic Environments Using Machine Learning
Authors: Jabla Roua , Khemaja Maha , Faiz Sami 
Published: May 2022

The proliferation of ubiquitous computing with smartphones makes context models and information extremely rich and dynamic on account of highly dynamic environments. However, defining rules at design time may impair their efficiency and the decision-making process at runtime. Therefore, it is important to address decision-making problems leveraged by dynamic environments and context-model evolution. In this sense, a solution that could emerge is the continuous rule knowledge base evolution at runtime. In this paper, we propose a decision adaptation component that relies on generating new rules due to changes occurring around users at runtime. This component aims to support decision-making in dynamic environments and to alleviate the human effort needed to infer new rules. A case study was conducted to illustrate the implementation of the proposed component for the rule knowledge database enrichment and the decision-making improvement. Moreover, an experimental evaluation is provided to assess the effectiveness of the proposed component. The results show that this component exhibits better effectiveness than other well-known algorithms and state-of-the-art approaches. Doi: 10.28991/HEF-2022-03-01-04 Full Text: PDF

Published: May 2022

Digitalization leads to increasing complexity and tight coupling of business processes. This increases the risk of "natural accidents". An answer to this proneness is a holistic mindfulness culture. The mindfulness dimension requires a holistic approach because it includes multiple aspects. This mindfulness should be reflected in the self-assessment of a company's employees. It is attempted to clarify whether social media allows an insight into how self-proclaimed qualifications are distributed in current enterprises. Social networks are particularly suitable because the members try to reflect the perceived demands of the companies while the characteristics presented are "quality assured" by connected members. More than 3500 profiles of senior IT managers were examined on the social network XING. COBIT has been used for categorization as a proven holistic approach for IT governance and structuring tool. The study shows that executives can be primarily categorized as generalists or specialists, both embracing a holistic perception, and therefore social media is suitable for general studies of qualifications in a business environment.

Electroretinography is a non-invasive electrophysiological method standardized by the International Society for Clinical Electrophysiology of Vision (ISCEV). Electroretinography has been used for the clinical application and standardization of electrophysiological protocols for diagnosing the retina since 1989. Electroretinography become fundamental ophthalmological research method that may assesses the state of the retina. To transfer clinical practice to patients the establishment of standardized protocols is an important step. It is important for monitoring successful molecular therapy in retinal degeneration. Retinitis pigmentosa or achromatopsia and, consequently, affected cones or rods photoreceptors is corresponded to complete absent of electrical response. Thus, detection of even modest improvements after therapeutic treatment is required. Standardized protocols allow the implementation of electroretinography under conditions of optimization of sensitivity and specificity during clinical trials. It should be noted that the literature on retinal diseases demonstrates clinical cases in which patients may have several retinal diseases at the same time. In such cases, it is necessary to detect a group of characteristics of electrophysiological signals with high accuracy to improve the application of various diagnostic solutions. The classification of electroretinogram signals depends on the quality of labeled biomedical information or databases, in addition to this, the accuracy of the classification results obtained depends not only on computer technology, but also on the quality of the input data. To date, the analysis of electroretinogram signals is realized manually and largely depends on the experience of clinicians. The development of automated algorithms for analyzing electroretinogram signals may simplify routine processes and improve the quality of diagnosing eye diseases. This article describes the formation of the parameters of pediatric electroretinogram database parameters for the development of doctor’s decision-making algorithm. The signal parameters were obtained by extracting the parameters from the wavelet scalogram of the electroretinogram signal using digital image processing and machine learning methods.
Art technologies in the development of students’ emotional intelligence
Authors: Larionova L. I. , Azarova L. N. 
Published: May 2022

The article presents an overview of domestic research devoted to the development of students’ emotional intelligence by means of art technologies. The relevance of the problem of developing emotional intelligence in modern students is determined by the objectives of higher education. Despite the serious experience gained in Russia in the use of art in teaching and personal education, the active penetration of art technologies into the education system began to occur relatively recently, which explains the time frame of the review study – 2019–2021. The analysis was performed in December 2021 using the national bibliographic database of scientific citation. The research was conducted using such combinations of keywords as “emotional intelligence”, “development of emotional intelligence of students”, “art therapy”, “pedagogical art therapy”, “art technology”, “art therapy at the university” in Russian for the period of 2019–2021. Out of 902 publications devoted to art therapy, the problem of using art technologies in higher education, the development of emotional intelligence through art technologies, the authors selected 49 publications. The analysis of the selected publications showed that the problem of the development of emotional intelligence arouses increased interest among researchers. However, the development of emotional intelligence in students is not a priority. In the system of professional education, the topic of emotional intelligence is not given enough attention, which is unacceptable and does not meet the requirements for the level of training of modern specialists. In recent studies, the possibilities of using art technologies in the development of students’ emotional intelligence have not been sufficiently disclosed. There is a need for further development of a program for the development of students’ emotional intelligence, presentation and description of art therapy techniques and techniques, their place and role in the development of emotional intelligence. Undoubtedly, building up the evidence base and substantiating methods for verifying the effectiveness of various art technologies will be a promising direction.
