OPTIMIZATION OF THE ENERGY SYSTEM AS AN INTEGRAL COMPONENT OF THE DEVELOPMENT OF THE UKRAINE’S INCLUSIVE ECONOMY
Authors: Saher L. , Vakulenko I. , Kolosok S.
Published: July 2022

Ukraine's modern energy is facing global challenges, the future of the country's economy and, consequently, its social sector depends on its ability to respond. High energy intensity of GDP and still high share of production using outdated energy technologies and production processes hinders the economic development of the country and has an extremely negative impact on the competitiveness of the economy.
The use of modern energy-efficient technologies increases the productivity of the energy network, and organizational and economic forms of attracting energy consumers to the energy system contributes to their rapid spread. Smart grids combine both components: energy efficient technologies and various forms of consumer involvement in power grid management. That is why the development of smart grids is a priority in Ukraine's energy sector, which requires modernization not only of the energy infrastructure of companies in the energy sector of Ukraine, but also modernization of equipment and processes in enterprises of all sectors.
Power grid optimization in the scientific and scientific-practical literature is used to denote activities with the use of technical and technological measures and tools to regulate the load on the network and bring it to optimal technical parameters. However, this article focuses on organizational and economic approaches to power grid optimization. In particular, mechanisms and measures to support renewable energy as part of a smart energy network, which contributes to the optimization of processes in the energy system, forms and maintains market mechanisms through which users are involved in more active participation in the energy system.
The article considers the indicators that characterize the current progress in the development of renewable energy in Ukraine, as well as the existing measures implemented for this purpose in the context of technically achievable potential for energy production from renewable energy sources and alternative fuels.

Authors: Vyas Jahnavi Nilay , Patel Prashant R , Patel Krutika , Bhagat Vasudha M
Published: July 2022

Introduction: Fine Needle Aspiration Cytology (FNAC) is a simple, safe, very low-cost and rapid procedure for diagnostic purpose which makes surgical intervention and exploratory laparotomy unnecessary. The introduction of modern diagnostic imaging techniques, mainly ultrasonography (USG) and Computerized Tomography (CT), has enabled the detection and location of lesions in sites such as liver, which are not easily accessible to surgical biopsies.

Aim: To assess the utility of FNAC in the diagnosis of liver lesions. To study the cytomorphological features, age and sex distribution of liver lesions.

Materials and methods: The study included 24 liver lesions which were detected clinically or radiologically. USG guided FNA was done in all cases. The smears were stained with Haematoxylin and eosin (H and E), May Grunwald Giemsa (MGG) and Papanicolaou’s stains. A cyto-histopathological correlation was done wherever possible. From the residual material, additional slides and cell blocks were prepared. Special stains were used whenever required. In doubtful cases immunohistochemistry (IHC) was done on formalin-fixed paraffin cell blocks and immunocytochemistry on conventional smears wherever necessary and possible.

Results: All the lesions were found to be malignant. Out of 24 liver FNA cases, maximum lesions were seen in females and the affected age group for liver malignancies was 51-60 years. Out of 24 liver FNA cases, 20 cases were metastatic and 4 were primary cases. Among metastatic cases, maximum cases were of metastatic adenocarcinoma and the primary lesions of liver included all cases of hepatocellular carcinoma. Conclusion: Fine needle aspiration cytology of liver is a simple, safe, repeatable and rapid diagnostic procedure. In case of hepatic lesions, it is of outmost advantage in recognizing the nature of lesion i.e., primary, and metastatic as well as in early diagnosis of lesion so that patient can be treated as early as possible.

Published: July 2022

Primary malignant of tumours of the testis are rare in children. Tumours of germ cell origin account for 60-77% of primary testicular tumors. Intrascrotal tumours of nongerm cell origin are rare. Rhabdomyosarcomas (RMS) are the commonest tumours among nongerm cell tumours. RMS are more commonly seen in paratesticular region. Pure testicular RMS are rare. A 16 yr boy was evaluated right sided testicular mass. Histopathology and immunohistochemistry confirmed it to be an anaplastic embryonal rhabdomyosarcoma. Here we report this case with a brief review of literature.

Authors: Thomas Shalu , Joseph Dahlia , Napolean Renny , Joseph Elizabeth
Published: July 2022

Rosai–Dorfman disease (RDD), or Sinus Histiocytosis with Massive Lymphadenopathy (SHML) is a self-limiting, rare benign proliferative disorder of histiocytes in the lymph nodes with occasional extra-nodal involvement of the skin. Isolated Cutaneous Rosai-Dorfman disease(C-RDD) without node involvement is an exceedingly rare occurrence. Despite its unique characteristics, the diagnosis of Cutaneous Rosai Dorfman disease is hampered by its variable clinical presentation, misleading histopathological patterns, and the absence of lymphadenopathy. Herein we present a case report of Cutaneous Rosai-Dorfman disease without any lymph node involvement.
Cytology of Bile Duct Brushings: Streaming Ahead with Time
Authors: Lahori Mega , Andotra Urvashi , Malhotra Aneeta Singh
Published: July 2022

Endoscopic retrograde brush cytology of the biliary duct is an established tool for evaluation of obstructive biliary strictures or screening of primary sclerosing cholangitis (PSC) patients for dysplasia. It is a simple, minimally invasive procedure that can be performed during a therapeutic ERCP. Most authors have reported a sensitivity of 30-60% and a specificity of 90-100%. A positive result can be a reliable indicator of malignant neoplasm. However, there is no standardized reporting terminology designed specifically for bile duct brushings. Majority of bile duct brushings yield either benign ductal epithelium, reactive atypia of ductal epithelium or suspicious/positive for malignancy. Diagnosing malignancy in bile duct brushings is based on a constellation of cytologic features, and consideration of the overall picture- clinical presentation, radiology/endoscopy findings, etc. Different studies have highlighted various key features for diagnosing malignancy in bile duct brushings. Features most consistently associated with a malignant category are- loss of honeycomb architecture, 3D clusters, high n:c ratio, anisonucleosis (≥1:4 variation), irregular nuclear outlines, coarse clumped chromatin, and single malignant cells in the background. The utility of biliary brush cytology has been expanded by using FISH, immunocytochemistry, and Next-generation sequencing.

Published: July 2022

In recent years, there has been a substantial progress in improving progression-free survival (PFS) and quality of life of multiple myeloma (MM) patients. This has become possible through implementation of novel drugs into clinical practice which were developed on the basis of multiomic molecular genetic studies in MM. The results of these studies also enabled to assess genetic heterogeneity of tumor cells in MM. That allowed to identify types and prevalence of single-nucleotide variations, structural chromosomal aberrations, and abnormal copy numbers of chromosomes in the genome of malignant plasma cells. It was shown that MM patients can have quite different spectra of detected genetic defects in the tumor. High genetic disease heterogeneity is one of the major causes of differences in drug efficacy and PFS. The present review comprehensively discusses the value of some chromosomal aberrations in risk stratification of MM patients. It describes the most prevalent aberrations, also those associated with high and low risk of early MM progression which have already been included in different international prognostic scores. Besides, the additional aberrations were determined which are potentially applicable in clinical practice. Special attention was paid to risk assessment in case a number of different chromosome rearrangements are identified in a patient. The review outlines challenges and prospects of dealing with the information on chromosome rearrangements in choosing the most optimal treatment strategy and assessing of its efficacy. In this context, emphasis is laid on integrating genetic data and such clinical parameters as age, comorbidity, renal failure, bone lesions, indications for autologous hematopoietic stem cell transplantation, etc.

Aim. To assess the detection rate of human herpes virus DNA (of cytomegalovirus, herpes simplex virus types 1 and 2 [HSV-1/2], human herpes virus type 6 [HHV-6], and Epstein-Barr virus) in different biological environments at different stages of autologous hematopoietic stem cell transplantation (auto-HSCT) as well as the effect of immune factors on reactivation of viruses under study. Materials & Methods. From 2019 to 2021 the study enrolled 87 lymphoma patients during and after auto-HSCT. Virological monitoring was performed on biological fluids (blood, saliva, urine, etc.) prior to conditioning regimen on Day 0 as well as on Day +5 and Day +10 after auto-HSCT. On these days (Day 0, Day +5, and Day +10) the immune factors (IgM, IgG, and IgA levels and pattern of lymphocyte subpopulation in peripheral blood) in 15 % (14/87) of patients were assessed in terms of their effect on herpes virus reactivation. Results. The overall rate of viral DNA detection increased from 26 % (26/87) to 42 % (37/87) of cases in the period of granulocytopoietic recovery. The most frequent were HHV-6 and HSV-1/2 reactivations reported in 23 % (20/87) and 16 % (14/87) of cases, respectively. The median B-lymphocyte proportion in peripheral blood of patients with herpes virus reactivation was 0.26 %, whereas in patients without reactivation it was 6.7 % (p = 0.019). The median absolute B-lymphocyte count in the cohort of patients with detected viral DNAs was 0.001 x 109/L, whereas in patients without them it was 0.098 x 109/L (p = 0.026). Conclusion. A high rate of herpes virus DNA detection in lymphoma patients after auto-HSCT affected neither transplant engraftment nor transplantation mortality. Immune predictors of virus infection reactivation were the decreasing proportion of B-cells in the total lymphocyte count and the absolute B-lymphocyte count in the peripheral blood prior to auto-HSCT.

Aim. To conduct a comprehensive study of morphological features of the genus Vigna plants, to assess their productive potential depending on the species characteristics under the conditions of introduction in the Right-Bank Forest-Steppe of Ukraine.
Methods. The main method of work was a comparative morphological analysis of plants grown from seeds. The research was carried out at the introduction sites and in the laboratory of the Department of Cultural Flora of the M. M. Gryshko National Botanical Garden of the National Academy of Sciences of Ukraine during 2019–2021. Plants of four species of the genus Vigna: V. radiata (L.) R.Wilczek, V. angularis (Willd.) Ohwi & H.Ohashi, V. mungo (L.) Hepper, V. unguiculata (L.) Walp were the material for the study. We studied the patterns of growth processes and plant development depending on species characteristics. Soil germination of seeds without prior preparation was determined depen ding on species characteristics. Field, laboratory and me thods of analysis of variance and statistical evaluation of average data using Microsoft Excel (2010) were used.
Results. It was revealed that the seeds of plants V. radiata, V. angularis, V. mungo, V. unguiculata being introduced in the Right Bank Forest-Steppe of Ukraine were characterized by a high level of sprouting energy (from 64.8% in V. angularis to 78.9% in V. unguiculata ) and germination (from 84.3% in V. radiata to 99.6% in V. angularis), the intensity of growth and development of aboveground and underground organs during the growing season and seed productivity (from 468 g/m2 in V. radiata to 585 g/m2 in V. mungo). This indicates the prospects of their cultivation as a source material for breeding research and the advisability of use in crop production, which will expand the potential of the raw material base in addition to traditional legumes and cereals.
Conclusions. The morphological characteristics of seeds, vegetative and reproductive organs of plants of the genus Vigna were studied. Peculiarities of formation of seed productivity, aboveground and underground part of plants during vegetation depending on species specificity in the conditions of introduction in the Right-Bank Forest-Steppe of Ukraine were determined.
Corruption as compensation for pathology of social relations
Authors: Romanov Mykhailo
Published: July 2022

The article is devoted to formulation of a new hypothesis about the essence of corruption as a mechanism and result of compensation of pathology of public life. It is noted that modern scientific research does not consider corruption comprehensively and systematically, but in its individual aspects. As a rule, the managerial and legal. Does not take into account its psychological origins and features of corrupt behavior. The article is aimed at formulating promising directions for the study of corruption, necessary for effective counteraction of this phenomenon. The relevance of the article is due to the possibility of identification of new directions of corruption prevention on the basis of revision of the causes of corrupt conduct.

Reforms to prevent corruption have been found to reduce corruption but have not had a decisive impact on corruption. In this regard, the author examines the characteristics of corrupt behaviour and concludes that it is in the mechanisms that give rise to it and it is necessary to look for the causes of corruption. However, in considering the psychological factors of corrupt behaviour, the author concludes that they are not independent and cannot be considered as a direct cause. Psychological characteristics, such as the need for moral revisions of individual values and the search for excitement in the work performed, clearly indicate the presence of contradictions or even pathologies at a deeper level. Given the high incidence of corruption, the author concludes that these pathologies are not individual, but rather indicative of systemic problems of social life. And since problems are not solved, corruption is a kind of compensation, a solution to these problems.

It formulates the conclusion, according to which corruption has a compensatory nature and is a unique indicator of the state of social relations and existing problems in them. It points to areas of society and individual members that require study, revision and correction. This approach makes it possible to understand that the direct preventive impact on corruption will not give stable qualitative results, because by influencing corruption we will influence the consequences. At the same time, the reasons will remain untouchable.
Ecosystem approach in international environmental law: from the idea of conservation of natural ecosystems to the emergence of a holistic concept
Authors: Suietnov Ye.
Published: July 2022

The article explores the historical foundations of the formation and development of the ecosystem approach in international environmental law from the idea of conservation of natural ecosystems to the emergence of a holistic concept within the framework of the Convention on Biological Diversity, which was adopted on June 5, 1992, and which considers the ecosystem approach as a strategy for the integrated management of land, water and living resources that promotes conservation and sustainable use in an equitable way.It has been proven that certain aspects of this approach can be traced in previously adopted acts, among which Declaration on the maritime zone 1952, Convention on Wetlands of International Importance Especially Waterfowl Habitat 1971, Declaration of the United Nations Conference on the Human Environment 1972, Convention on International Trade in Endangered Species of Wild Fauna and Flora 1973, Great Lakes Water Quality Agreement 1978, Convention on the Conservation of Migratory Species of Wild Animals 1979, Convention on the Conservation of European Wildlife and Natural Habitats 1979, Convention on the Conservation of Antarctic Marine Living Resources 1980, World Charter for Nature 1982, United Nations Convention on the Law of the Sea 1982, Declaration on Conservation of Flora, Fauna and their Habitats 1988, Convention on the Protection of the Alps 1991, Convention on the Protection and Use of Transboundary Watercourses and International Lakes 1992, Convention on the Protection of the Marine Environment of the Baltic Sea Area 1992, Convention on the Protection of the Black Sea Against Pollution 1992, Declaration on Environment and Development 1992, etc.On the basis of a thorough analysis of the above-mentioned and other international legal documents, the conclusion is made about their influence on the process of formation of the ecosystem approach at the international level.
Assessment of groundwater quality using water quality index (WQI) and multivariate statistical analysis in Amman-Zarqa area/Jordan
Authors: Hyarat Tasneem , Al Kuisi Mustafa , Saffarini Ghazi
Published: July 2022

The evaluation of the relevant physical and chemical parameters of 246 samples of groundwater quality from the Amman-Zarqa area showed that most of the parameter values exceeded the maximum permissible limits for drinking according to the Jordanian Institute of Standards and Meteorology. Based on the hydrochemical analysis, the water can be classified into four distinct water types using the Piper diagram, whereas, the hydrogeochemical process that affects the groundwater parameters is the dissolution or mixing process as indicated by the Durov diagram. The correlation between the different parameters showed that the basic ionic composition of the water samples is directly influenced by physicochemical parameters and anthropogenic activities. Additionally, factor analysis has been conducted and three factors were extracted. The three factors account for the ‘salinity’, ‘hardness’, and ‘pH’ properties and were named accordingly. These three factors accounted for 78.5% of the total variance of the data composition. Furthermore, a hierarchical cluster analysis of the 246 samples was carried out and three groups were obtained to verify the factor analysis results. Based on water quality index values, 12% of the groundwater samples can be described as ‘excellent’ and 53% of ‘good’ quality. The remaining 35% of the samples are of ‘fair’ and ‘poor’ qualities. These findings are important in understanding the sustainability of groundwater for drinking purposes in the study area.

Environmental factors influence positively or negatively for the establishment of natural pine s regeneration, which may be linked to forest fires. Therefore, the objective of this study was to determine the environmental variables that influence the establishment of natural pines regeneration in impacted areas under three fire severity conditions (no fire, moderate fire and extreme fire) in pine - oak forests (Pinus lumholtzii BL Rob. & Fernald, Pinus devoniana Lindl., Pinus oocarpa Scheide, Quercus castanea Née, Quercus magnoliifolia Née) in the state of Jalisco (Mexico). For this purpose, different parameters of natural regeneration were evaluated: trees, live and dead fuels in circular sites of ~400 m2. Correlation analyses were performed with the data obtained to identify the most significant variables, and to use them in the stepwise regression analyses to identify predictor variables useful for the definition of the model for the estimation of natural pine regeneration in areas affected by fire. The analyzes showed that the "stepwise" process presents the best model with an R2 of 0.6837 and an AIC of 568.58, selecting the following variables: dry weight of herbs, height of shrubs, crown diameter of shrubs and grasses, 10 hour fuels and exposure. Subsequently, considering the mean square of the error as the main criterion, a comparison was made of the models resulting from the combination of these variables, with the best model excluding the dry weight of herbs. It is concluded that the establishment of the natural regeneration of pine is associated with certain variables of ground cover, understory and relief.
PERSPECTIVAS DEL MANEJO DE LA FAUNA EN AMÉRICA LATINA
Authors: Dourojeanni Marc J.
Published: July 2022

El manejo de la fauna silvestre como ciencia aplicada es nuevo en América Latina. Aunque hubo algunos casos pioneros previos, como en el caso de las aves guaneras en el Perú, la mayor parte de los programas y proyectos fueron iniciados apenas en las décadas de 1960 y especialmente de 1970, cuando también se inició la formación académica especializada. Actualmente hay muchas operaciones de manejo de fauna en todos los países de la región. Pero, en su inmensa mayoría tienen fines de conservación, es decir se hacen para recuperar las poblaciones de especies raras o amenazadas y/o para estimular el turismo. No son realizados para estimular el desarrollo económico y social a través de la producción de carne y otros productos que pueden comercializarse, aunque en algunos casos eso pueda ocurrir. Una de las pocas excepciones es el ya bastante generalizado manejo de las tortugas de río amazónicas que sirve para mejorar la alimentación de las poblaciones ribereñas. Otra es la caza deportiva que aún es tolerada en unos pocos países, como en Argentina. El principal obstáculo para la aplicación del manejo de fauna convencional es la información ambiental distorsionada que la sociedad recibe y su consecuente fuerte oposición a la caza, a la que considera inhumana y peligrosa para las especies. De otra parte, influenciadas por la actitud de la sociedad, las políticas y leyes referidas a la fauna silvestre son deficientes e ineficientes, siendo generalizada la caza ilegal y el tráfico de fauna. El futuro para el manejo de la fauna con fines económicos directos en la región no se muestra favorable. Sus mayores posibilidades se dan principalmente en las porciones de ecosistemas naturales poco habitados, especialmente bosques tropicales, para beneficio de las poblaciones indígena y rurales, donde hoy se practica la caza para sustento en forma desordenada.

Published: July 2022

Of many manufacturing processes, sand casting is one of the most widely used since there is no size limit of the workpiece. Big size product can be carried out at an affordable cost. In its process, sand casting comprises interconnected and complex series. If some of the processes are not properly carried out e.g. during solidification, will result in defects in the casting products. Simulation is an important method currently since it can model the entire metal casting process and show the dynamic character of the casting scheme. In this study, CAD is used for a 3D design on casting simulation. In this study, the grain size of molded sand, material quality and other process parameters were considered identical to all design schemes. This study aims to investigate the effect of varied design and dimensions of the gating system. It was found in this study that porosity and improper solidification were related to the improper gating and riser design.
Visitantes florales en el cultivo de Phaseolus coccineus (Fabaceae) en el Altiplano de Puebla, México: importancia del manejo agrícola y color de flor
Authors: Cué-Hernández Karina Alejandra , Gil Muñoz Abel , Aguirre-Jaimes Armando , López Pedro Antonio , Taboada-Gaytán Oswaldo Rey
Published: July 2022

Antecedentes y Objetivos: Phaseolus coccineus es una planta alógama, con variación en color de la flor, que depende de polinizadores para su reproducción. La especie se cultiva bajo dos modalidades, una en la cual no se emplean agroquímicos para controlar arvenses y plagas (manejo tradicional) y otra en la que sí se usan (manejo tecnificado). No existen estudios que hayan evaluado la importancia del manejo agrícola y color de flor sobre los visitantes florales de esta especie, por lo que nuestro objetivo fue analizar cómo influyen estos factores en la diversidad y frecuencia de visitantes florales de P. coccineus. Métodos: Se estudiaron dos variedades de P. coccineus (de flor blanca y roja), cultivadas bajo dos sistemas de manejo diferentes. En el pico de floración, durante ocho días, se realizaron observaciones simultáneas, contabilizando el número de visitantes florales y de visitas. Se calculó la riqueza específica y los números de especies efectivas como medida de diversidad, se aplicaron pruebas de chi-cuadrada, se practicó un análisis de correspondencias y se construyeron gráficos de rango-abundancia. Resultados clave: Se registraron 42 morfoespecies, agrupadas en seis órdenes; predominaron Apis mellifera e Hylocharis leucotis. El número de visitas registradas fue de 1613 y 1105 en manejo tradicional de flores blancas y rojas, respectivamente, y de 1427 y 815 en el manejo tecnificado, existiendo diferencias estadísticas consistentes entre manejos, no así para color de flor. En flores blancas, el manejo tradicional fue dos veces más diverso que el tecnificado; en flores rojas, la diferencia fue de 1.26 veces. Conclusiones: La diversidad y frecuencia de visitantes florales de P. coccineus se ven favorecidas por el manejo agrícola tradicional, ello fundamenta la conveniencia de fomentar esta modalidad de cultivo. Bajo las condiciones estudiadas, el color de flor no influyó en la riqueza de especies, ni mostró tendencias definidas en la frecuencia de visitas.
Managing crisis communication by tourism actors in the new normal era at the beaches of Yogyakarta
Authors: Wijayanti Yani Tri , Handini Handini , Dewi Maya Sandra Rosita , Attaymini Rahmah
Published: July 2022

Yogyakarta is one of the destinations in Indonesia affected by the Covid-19. Currently, tourist objects in Yogyakarta are gradually starting to open to the public, and one of them is beach tourism, although it can lead to a new cluster risk of the spread of Covid-19. According to the Texas Medical Association, traveling to a beach is included in a moderate risk with a score of 5-6, and health protocols are still required. Applying the crisis management and crisis communication model of Coombs, J, Holladay, this study analyzes how tourism actors manage crisis communication at the beaches of Yogyakarta in the new normal era. A qualitative case study approach was used to illustrate that crisis communication management is an effort to manage a crisis to provide solutions to the beach tourism due to the Covid-19. Crisis management consists of stages, for example, pre-crisis, crisis, and post-crisis. Through these stages, tourism actors and tourists can determine steps they must prepare for during the Covid-19 crisis. In order to resolve the crisis during the pandemic, it is necessary to adopt new habits by tourism actors and tourists. New habits need to be communicated directly or through existing media because communication is essential in crisis resolution.
Preliminary Real-World Evidence Supporting the Efficacy of a Remote Neurofeedback System in Improving Mental Health: Retrospective Single-Group Pretest-Posttest Study
Authors: Whitehead Jocelyne C , Neeman Ron , Doniger Glen M
Published: July 2022

Background

Neurofeedback training (NFT) has been shown to be effective in treating several disorders (eg, attention-deficit/hyperactivity disorder [ADHD], anxiety, and depression); however, little is currently known regarding the effectiveness of remote NFT systems.

Objective

This retrospective study provides real-world data (N=593) to assess the efficacy of app-based remote NFT in improving brain health and cognitive performance.

Methods

Improvement was measured from pre- to postintervention of in-app assessments that included validated symptom questionnaires (the 12-item General Health Questionnaire, the ADHD Rating Scale IV, the Adult ADHD Self-Report Scale, the 7-item Generalized Anxiety Disorder scale, and the 9-item Patient Health Questionnaire), a cognitive test of attention and executive functioning (ie, continuous performance task), and resting electroencephalography (EEG) markers. Clinically significant improvement was evaluated using standard approaches.

Results

The greatest improvement was reported for the anxiety questionnaire, for which 69% (68/99) of participants moved from abnormal to healthy score ranges. Overall, adult and child participants who engaged in neurofeedback to improve attention and executive functions demonstrated improved ADHD scores and enhanced performance on a cognitive (ie, response inhibition) task. Adults with ADHD additionally demonstrated elevated delta/alpha and theta/alpha ratios at baseline and a reduction in the delta/alpha ratio indicator following neurofeedback.

Conclusions

Preliminary findings suggest the efficacy of app-based remote neurofeedback in improving mental health, given the reduced symptom severity from pre- to postassessment for general psychological health, ADHD, anxiety, and depression, as well as adjusted resting EEG neural markers for individuals with symptoms of ADHD. Collectively, this supports the utility of the in-app assessment in monitoring behavioral and neural indices of mental health.

Authors: Gao Yankun , Xie Zidian , Li Dongmei
Published: July 2022

BACKGROUND

On May 18, 2020, the New York State Department of Health implemented a statewide flavor ban to prohibit the sales of all flavored vapor products, except for tobacco or any other authorized flavor.

OBJECTIVE

This study aims to investigate the discussion changes in e-cigarette–related tweets over time with the implementation of the New York State flavor ban.

METHODS

Through the Twitter streaming application programming interface, 59,883 e-cigarette–related tweets were collected within the New York State from February 6, 2020, to May 17, 2020 (period 1, before the implementation of the flavor ban), May 18, 2020-June 30, 2020 (period 2, between the implementation of the flavor ban and the online sales ban), July 1, 2020-September 15, 2020 (period 3, the short term after the online sales ban), and September 16, 2020-November 30, 2020 (period 4, the long term after the online sales ban). Sentiment analysis and topic modeling were conducted to investigate the changes in public attitudes and discussions in e-cigarette–related tweets. The popularity of different e-cigarette flavor categories was compared before and after the implementation of the New York State flavor ban.

RESULTS

Our results showed that the proportion of e-cigarette–related tweets with negative sentiment significantly decreased (4305/13,246, 32.5% vs 3855/14,455, 26.67%, P<.001), and tweets with positive sentiment significantly increased (5246/13,246, 39.6% vs 7038/14,455, 48.69%, P<.001) in period 4 compared to period 3. “Teens and nicotine products” was the most frequently discussed e-cigarette–related topic in the negative tweets. In contrast, “nicotine products and quitting” was more prevalent in positive tweets. The proportion of tweets mentioning mint and menthol flavors significantly increased right after the flavor ban and decreased to lower levels over time. The proportions of fruit and sweet flavors were most frequently mentioned in period 1, decreased in period 2, and dominated again in period 4.

CONCLUSIONS

The proportion of e-cigarette–related tweets with different attitudes and frequently discussed flavor categories changed over time after the implementation of the New York State ban of flavored vaping products. This change indicated a potential impact of the flavor ban on public discussions of flavored e-cigarettes.
Trends in Tattoo-Related Google Search Data in the United States: A Time Series Analysis (Preprint)
Authors: Kiszla Benjamin Matthew , Harris Mia Broughton
Published: July 2022

BACKGROUND

Tattoos are becoming increasingly common in the United States. However, little information is available to help clinicians anticipate where, when and what patients will seek guidance on regarding tattoo care, complications, and removal.

OBJECTIVE

The aim of this study was to model web searches concerning general interest in tattoo application and removal, geolocation of tattooing services, and investigations of adverse reactions to tattoos.

METHODS

Relative search volumes (RSVs) were elicited from Google Trends, filtered to web searches in the United States made between February 20, 2008 and June 20, 2022. Longitudinal data was analyzed in GraphPad Prism and geospatial data was visualized with Datawrapper for general interest searches (“tattoo” and “tattoo removal”), geolocating searches (“tattoo shops near me”), and symptomatic searches relating to adverse effects (“itchy tattoo,” “raised tattoo,” “swollen tattoo,” “tattoo bumps,” and “tattoo fading”).

RESULTS

The topics of “tattoo” and “tattoo removal,” have experienced stable RSVs over the past 14 years, with the former peaking most often in July (11/14, 78.6%) and the latter peaking most often in June (5/14, 35.7%) and July (4/14, 28.6%). RSVs by state for the two search topics were loosely associated with lower latitudes (“tattoo” R2=0.2051, “tattoo removal” R2=0.2060). Searches for “tattoo shops near me” localized to the Southeast and Midwest over the time range with the highest RSVs being logged for Tennessee (100), followed by Alabama (91), Georgia (89), North Carolina (85), and then South Carolina (83). Regarding searches for symptoms related to adverse reactions to tattooing, “itchy tattoo” experienced the largest percent increase (1010%), followed by “raised tattoo” (736%), “tattoo bumps” (422%), “swollen tattoo” (301%), and then “tattoo fading” (64.4%).

CONCLUSIONS

Clinicians should be aware of an increase in search interest regarding tattoos and their removal during the Spring and Summer. Geolocating searches for tattooing services are localizing to the Southeast and Midwest. Searches regarding pruritis and edema localized to tattoos are increasing relative to those for more generalized edema and tattoo fading.

Internet-based Parent Training with Telephone Coaching on Managing Disruptive Behavior in Children During The COVID-19 Pandemic (Preprint)
Authors: Sourander Saana , Sourander Andre , Hinkka-Yli-Salomäki Susanna , Ristkari Terja , Kurki Marjo
Published: July 2022

BACKGROUND

There is growing concern about the short-term and long-term impact that the COVID-19 pandemic will have on the mental health and psychosocial well-being of children and families. There are no existing studies about feasibility and outcomes using Internet-based Parent training programs with telephone coaching for disruptive behavioral problems in childhood during COVID-19 pandemic in clinical settings.

OBJECTIVE

This study explored how the Strongest Families Smart Website (SFSW) parent training program, with telephone coaching, provided support during COVID-19 pandemic at specialist family counselling centers in Helsinki, when restrictions made face-to-face counselling impossible. This study followed the success of an RCT and its implementation study of the SFSW parent training program by primary care child health clinics. The aim was to improve parenting skills, so that they could tackle disruptive behavior by developing positive parent-child relationships. It started in May 2020, when the COVID-19 pandemic was at its height in Finland.

METHODS

Eight family counselling centers in Helsinki, Finland, identified 50 referrals aged 3-8 years with high levels of parent-reported disruptive behavioral problems. Child psychopathology and functioning and parental skills and well-being were measured at baseline, post-treatment and six months later using a range of tools. The data were extracted from questionnaires completed by the parents.

RESULTS

We found that 44 (88%) families completed the whole 11 session parent training program. Most of the children (96%) had definitive or severe behavioral problems when they were initially screened by the centers, but this dropped to 58% at the six-month follow-up assessment. There were significant changes from baseline to 6 month follow up in most of the child psychopathology measures, including CBCL externalizing score (change in mean score 16.3, 95% Cl 10.2 to 22.3; P <.001) and total score (7.0, 95% Cl 4.9 to 9.0; P<.001). When parenting skills were measured with the Parenting Scale, they showed significant changes from baseline to six-month follow-up in total scores (0.5, 95% Cl 0.4 to 0.7; P<.001). Parents showed significant change in stress sub score (3.9, 95% Cl 2.2 to 5.6; (P<.001). They reported high satisfaction, varying from 93.3%-97.8%, in the skills and professionalism of the telephone coaches.

CONCLUSIONS

The program proved to be an effective method for improving parenting skills and child psychopathology and functioning. The parents were very satisfied with the program and the drop-out rate was exceptionally low. The study shows that the training program could be implemented in specialist clinical settings and during crisis conditions like the COVID-19 pandemic.

In this paper, I have tried to explore and explain the significance of “short square fingers” in Preludes. The meaning becomes clear if we analyse the image from the angle of palmistry and we understand how it fits in with the meaning and theme of the poem.
A Survey on Machine Learning Based Techniques for Sign Language Translation System
Authors: Shambuwani Harsh
Published: July 2022

Abstract: Sign language is the communication method used to bridge the gap among mute and deaf people and the rest of the people. But most people are not familiar with sign language, so communication becomes difficult among mute, deaf and the rest of the people. Improvement in machine learning technology has led to research on its application in sign language recognition and translation system. This paper presents a review of different sign language recognition and translation systems and the various techniques like classification algorithms that were implemented in them. We have found that although many sign language recognition and translation system exist none of them provides efficient and real-time conversation of sign language into audio and many sign language recognition and translation system are hand movement sensor-based which are not affordable to everyone. So, we have also discussed a sign language translation system integrated into a video calling application, in which we will be using a single shot multibox detector for hand detection, for feature extraction Inception V3 will be used, and support vector machines for classification, attention network for generating semantically correct sentences and a text to speech synthesizer for audio output. This system will be easy to access and affordable as it use
Improving the Stiffness for Rear Panel of a Washing Machine
Authors: Kumar T. Ravi
Published: July 2022

Abstract: Various products such as refrigerators, mobile phones, televisions, washing machines, remote controls, telecommunication and military equipment, etc. are subjected to drop tests to assess their fragility and impact tolerance. It is difficult and expensive to understand the effect of various parameters on the product performance during the test. Finite element simulations using LS-DYNA® effectively help to understand these effects. In this paper we have improved the stiffness of a rear panel of a washing machine by integrating new plastic parts called spacers and metal reinforcement plates. To get the best results we have considered the pre-stresses as well.
