Certain Problems of Researches of Slavery in the Caucasus as Holistic Phenomenon in Modern Russian-Speaking Historiography. Part I
Authors:   Cherkas Global University, Peretyatko Artyom Yu.
Published: June 2023

The article is devoted to the analysis of modern Russian historiography of slavery in the Caucasus. The author comes to the conclusion that despite a heightened attention to local and individual cases, the works describing Caucasian slavery in general are rather few, and they have appeared relatively. Therefore, there is no unified comprehensive picture of slavery in the Caucasus, and even evaluation of its cruelty can differ dramatically. The first part of the article introduces terminological definition of Caucasian slavery and clarifies the context in which it should be studied. It shows that researchers usually don’t define the very concept of “slavery”, which leads to serious distortions: sometimes only one of the types of Caucasian slavery is termed “slavery”, whereas others are ignored; sometimes various forms of dependence are blended under one definition of “slavery”, etc. The author suggests that the term should be defined in the researches to avoid serious distortions of terminological and conceptual nature. As a context for the study of slavery, the author proposes using the history of the Black Sea slave trade locus. Russian influence in the region became predominant in the 19th century, and the main forms of Caucasian slavery were shaped under social conditions completely atypical of Russia. The very approach to slavery characteristic of the Caucasus was based on Mediterranean Islamic practices and cannot be properly understood outside of them. Finally, only in consideration of the relative mildness of certain forms of Mediterranean slavery can some Caucasian customs, such as selling one’s children into slavery, be understood.
Slovak temporal adverbs mnohokrát and veľakrát, the specificity of lexical meaning according to compatibility data
Authors:   Institute of Slavic Studies of the Russian Academy of Sciences, Vashchenko Daria Yu.
Published: June 2023

The article considers the issue of synonymy/quasi-synonymy of the Slovak temporal adverbs mnohokrát and veľakrát, which belong to the semantic group “often”, based on the material of the Slovak National Corpus. The meaning of the lexemes included here assumes that a certain situation is repeated, and the speaker considers the number of such repetitions to be high. The analysis is carried out on the base of the compatibility of these adverbs in the Corpus. First, the indicators of the logDice association measure (the distance between collocates from –6 to 6 tokens) are considered, it is shown that the lists of words ranked by this measure are mostly the same for both lexemes, veľakrát has a certain specificity, which has a high degree of association with adverbial modifiers marking an extremely high frequency of a situation, or with constructions suggesting a detailed explication of its causes. The frequency context of the appearance of both adverbs in the text is thus a comparison of the real state of affairs with the desired one. In the second part of the article, the joint occurrence of adverbs from this semantic group is considered, including the compatibility of mnohokrát and veľakrát with the more frequent adverbs často and neraz. In this case, mnohokrát and veľakrát are used either for a detailed explication of the state of affairs, or to indicate directly observed situations. As follows from the analysis, the adverbs mnohokrát and veľakrát are almost complete synonyms, the difference between them is that the specified specificity of the meaning (high frequency of repetition, direct observability) is more pronounced in veľakrát than in mnohokrát.
Contro tutto e contro tutti: The linguistic pragmatics of protest in the Italian futurists’ manifestoes
Authors:   Institute of Linguistics, Russian Academy of Sciences, Sokolova Olga V.
Published: June 2023

The speech act theory by J.L.Austin and the conception of the degree of strength of illocutionary force (point) by J.R. Searle and D.Vanderveken underlies the study of exercitive speech act as the act of objection/protest expressed by prepositions contro and against ‘против’. Historically, protest as a genre goes back to the Ancient rhetorical tradition, but in the 20th century, it has also become an aesthetic foundation of the Avant-garde poetic discourse. The expression of protest and a critical attitude towards the dominant discourse become one of the grounds for the interaction of the Avant-garde poetic and political discourses. Discourse and linguopragmatic analysis of the Italian Futurists’ manifestos is carried out from the standpoint of the linguistic creativity that manifests itself in the form of the Avant-garde linguistic experiment. Further, the Italian Neo-avant-garde (Neoavanguardia, Gruppo ‘63) develops the idea of confronting linguistic and cultural norms in its poetical texts and manifestoes like Linguaggio e opposizione (1961) by Nanni Balestrini or Ideologia e linguaggio (1965) by Edoardo Sanguineti. The markers of adversative semantics include such grammatical and lexico-grammatical means as но, однако, впрочем, против, напротив, вопреки, наперекор; ma, anzi, mentre, però, bensì, pure, eppure, contro, piuttosto, etc. The paper focuses on the pragmatic and semantic features of the preposition contro as one of the most frequent opposition markers in the Italian Futurists’ manifestos. The study distinguishes methods of deviation from standard use, aimed at increasing the illocutionary force and the performative potential of the message.

To improve and maintain dental health among the population today, the leading task of primary prevention is to increase motivation in individual oral hygiene. The low level of oral hygiene comes to the fore, which forms the hygienic and dental status, leading to an increase in the prevalence of caries and inflammatory periodontal diseases in the population. The survival of dental prophylactic knowledge, taking into account the hygienic and periodontal status in the adult population, was studied to determine the need for dental hygiene education and upbringing. Preservation of dental hygiene knowledge determines the level of dental health in the adult population. The leading feature of the prevention of major dental diseases among various groups is the constant repeated “hygiene lessons” in the adult population, taking into account their dental status, which maintains a higher level of preservation of preventive knowledge and motivation to take the necessary actions. The ongoing monitoring made it possible to correct the preventive focus of sanitary and educational work, which increased the level of dental health among the population.

Analyzed the work of the hypertension prevention cabinet in working people, with risk factors for the cardiovascular diseases’ development and their influence on hypertension. The aim of the study was the causes and frequency of risk factors’ complications for the development of cardiovascular diseases in working people applying in primary health care to the hypertension prevention office. The study was conducted in the typical primary health care “City Polyclinic no. 91” in St. Petersburg from 2014 to 2018. The increase of the attached population during the study averaged 1,000 people annually. Simultaneously, medical appeals for the preventive purpose of the able-bodied population (Z00–Z13) had been parabolic changing, with the peak in 2015 and 2016, which is 8.5 times more than in 2014. The number of visits to this office from 2014 to 2018 had been decreasing. The frequency occurrence of absolute cardiovascular risk was decreased through men and women 50 years and older by 2018, while in women the reduction was fixed at 2 times more. We noted a high risk in women aged 18–40, the level of which was 2 times higher than in men at the same age and which increased to 6.5 % by 2018.

Closely related to the development of the healthcare system is the trend toward an increase in medical waste. Updating the indicative standards for the generation of class B medical waste is necessary for the correct operation of all sequential processes for handling medical waste. Predicting the amount of class B waste generation makes it possible to optimize work in medical organizations and reduce risks to the health of staff and patients. In this work, we noted a significant increase in the generation of medical waste of class B in multidisciplinary hospitals and Outpatient clinics in St. Petersburg and the Leningrad Region, as well as an increase in the fraction of plastic in the composition of medical waste, a statistical evaluation of the results was carried out and indicative standards for the formation of medical waste of class B were proposed. data on indicative standards for waste generation in departments are extremely relevant due to the different fractional and morphological composition of waste, an extremely high potential infectious risk (including the spread of multidrug-resistant strains) in a number of them, for example, in intensive care units, hemodialysis, and surgery.
In the wake of one publication, or about the attitude to the history of science as a science
Authors:   St. Petersburg State Pediatric Medical University, Kozhukhar Vladimir
Published: June 2023

The article is a historical investigation devoted to reliability of Professor T. A. Ginetsinskaya’s publication about the circumstances of Professor E. S. Danini’s speech (December 1954) criticizing O. B. Lepeshinskaya’s “new cellular theory”. After analyzing scientific sources, memoirs of contemporaries of the described events and comparing the dates, the author proves that E. S. Danini’s speech in the context given in T. A. Ginetsinskaya’s article could not have taken place in reality. It took place in other circumstances and was not so dramatic. This is indicated by the documented memories of eyewitnesses and participants of the meetings, as well as materials of speeches by members of the Society of Anatomists, histologists and embryologistsat the Institute of Experimental Medicine (including E. S. Danini). In addition, it is shown that criticism of Lepeshinskaya’s “new cellular theory” had begun much earlier than December 1954. The article provides data of numerous critical speeches about Lepeshinskaya’s theory at various meetings in 1953 and 1954. Criticism of Lepeshinskaya’s views by the end of 1954 ceased to pose a danger to critics, and therefore the drama of the situation described in Ginetsinskaya’s article does not seem to correspond to the realities of that time.
The Russian version of Inventory of the Dimensions of Emerging Adulthood (the IDEA-R): Developmental features of university students
Authors:   Financial University under the Government of the Russian Federation, Кlementyeva Marina
Published: June 2023

Emerging adulthood is a new liminal period ranging from 18 to 25 years, and is a trend in most of today’s industrialized societies. Its key psychological dimensions have been explored in many countries through the IDEA (Inventory of the Dimensions of Emerging Adulthood) instrument, but not in Russia. The goal of the present study was to measure the psychometric properties of the IDEA-R in Russia. This study applied an adaptation of the IDEA-R to 410 Russian students aged 18 to 25, whose educational level ranged from Bachelor’s to Master’s of higher school. An Satisfaction With Life Scale (SWLS) and the Zimbardo Time Perspective Inventory (ZTPI) additional measures were used. Exploratory factorial analysis pointed out that the IDEA-R adapted to the Russian context presented a six-factor structure. These factors are: identity exploration/self-focus, instability/negativity, personal freedom, experimentation/possibilities, feeling “in-between”, other-focused. The measure has the internal consistency (Cronbach’s α=0.82) and stability in time (ρ=0.62). Age reduced the levels of the perception of experimentation/possibilities (p=0.001) and feeling “in-between” (p<0.001). We found that the participants who reported higher levels of SWLS and the ZTPI exhibited lower level instability/negativity (p ≤ 0.001), but higher levels identity exploration/self-focus, and experimentation/possibilities (p ≤ 0.001). In conclusion, the IDEA-R is a valid and reliable instrument of investigation of the emerging adulthood phenomenon in Russia and to provide data for comparison of the measure in different countries.

An attempt has been made to study the experiences of transgender people in the conditions of their living in a critical life situation (transgender transition). The study included conducting and analyzing a semi-structured interview, as well as collecting and analyzing quantitative data using an author’s questionnaire compiled on the basis of content analysis of interview texts. 10 transgender people (average age 21.2 years) took part in the interview, 285 transgender a Author for correspondence. Вестник СПбГУ. Психология. 2023. Т. 13. Вып. 2 227 people (average age 21.21 years) took part in the survey. The analysis of the phenomenology of experiences and subsequent verification by mathematical methods (hierarchical clustering and the Mann — Whitney U criterion for independent samples) made it possible to identify and describe two types of experiences of transgender people: “open to self-search” (81 people) and “avoidant” (204 people). “Open to self-search” transgender people more often gave high marks to positive states and emotions about transgender transition, noted the experience of community with transgender people. In the process of transgender transition, new meanings were produced: cognition, acceptance and self-development; life planning and the importance of building future goals; professional development. Family, partner and friendly support were assessed by them as positive or favorable social factors. “Avoidant” transgender people more often noted negative states and emotions about transgender transition, and avoidance of communication with people. They note the experiences associated with doubts and assessment of the correctness of the transgender transition, with excitement about the reactions of people around them to transgender status, with a feeling of loneliness among cisgender people. The negative attitude of the family, loved ones and others, as well as discrimination in public places were considered as interfering with the transgender transition and life in general. This study serves as an attempt to phenomenologically describe the experiences of transgender people accompanying a transgender transition, as well as to identify differences in them.
Examining trends in temperature and precipitation mean/extremes over Gandaki Province, Nepal
Authors: Adhikari Adarsha Pratap , Mathema Ajay Bhakta
Published: June 2023

Despite the increased frequency of extreme climate events including their significance in Nepal's socio-economy, climate studies have seldom considered extremes, and even fewer have considered them in combination with temperature and precipitation. This study aimed at examining the trend of climate variables in Gandaki Province, Nepal. Daily temperature and precipitation data of five stations between 1990 and 2020 were analyzed. Modified Mann–Kendall and Sen's slope methods were used to detect trend and magnitude. The Mann–Whitney–Pettitt test was used to detect abrupt changes, and the Pearson correlation coefficient was used to find the correlation. The result showed an increasing trend and a significant abrupt change in the maximum temperature for all stations. A decreasing trend in the minimum temperature was observed in the Himalayas and the Hill region, whereas an increasing trend was seen in Siwalik and Terai regions. The Jomsom station, however, behaved differently by showing an increasing trend in precipitation and the number of rainy days. The majority of the temperature indices showed an increasing trend unlike precipitation indices, which showed a mixed result. The maximum five-day precipitation and consecutive dry days showed a significant positive correlation with altitude. The results indicate an increase in the frequency and intensity of extreme climate conditions in Gandaki Province.

We aimed to assess the physical, chelating, antibacterial properties and cytotoxicity of EDTA used with and without antibacterial additives. Material and methods: Solutions of 17% EDTA with or without additives together with 2.5% sodium hypochlorite and saline control were tested. The antibacterial properties of the solutions were assessed using a biofilm which was inoculated in human dentine either before exposure to irrigating solution or after. The smear layer removal capacity was tested by using scanning electron microscopy (SEM). The irrigants were also evaluated for dentine wettability by the sessile drop method, and the surface tension of solutions was verified by the pendent drop test. The effect of irrigating solutions on fibroblast cell viability was assessed by reducing MTT assay. Results: The addition of antibacterial substances to EDTA resulted in improving its antibacterial action against Enterococcus faecalis biofilm, without compromising the EDTA chelating action or elevating its cytotoxicity. Lower surface tension and better wettability of the irrigants was obtained by sodium hypochlorite or by adding benzalkonium chloride or N-acetylcysteine to EDTA. Conclusion: EDTA-benzalkonium chloride showed effectiveness not only preventing the formation of biofilm and root canal re-infection, but also against Enterococcus faecalis biofilm itself. It also lowered EDTA surface tension and allowed better dentine wettability, being outstanding compared with the other chelator solutions. Therefore, the use of this association as a final rinse in endodontic treatment should be further studied.

Published: June 2023

O traumatismo dentoalveolar constitui um fator etiológico responsável pela perda de grande número de dentes e muitas vezes está associado a traumas faciais. O tratamento de urgência é bastante complexo. Assim, uma boa anamnese, um exame clínico detalhado e a solicitação de exames complementares são de extrema importância na instituição de um plano de tratamento rápido e adequado. Objetivo: Avaliar a incidência de traumas dentoalveolares associados a traumas faciais ocorridos no período de três anos no Hospital Municipal São José (grupo 1) e Hospital Infantil Dr. Jeser Amarante Farias (grupo 2), em Joinville (SC). Material e métodos: A coleta de dados foi realizada por meio da análise dos prontuários de pacientes atendidos no período de janeiro de 2016 a janeiro de 2019. Resultados: No grupo 1, em 85,78% dos casos não ocorreu trauma facial associado a trauma dentoalveolar e em 14,22% houve trauma facial com envolvimento dental. No grupo 2, 100% dos pacientes tiveram trauma facial associado a trauma dentoalveolar. Conclusão: Com base nos resultados encontrados por meio da revisão sistemática de prontuários nos hospitais analisados, conclui-se que os traumas dentoalveolares devem ser considerados tão importantes quanto os traumas faciais nas emergências hospitalares.

Published: June 2023

O conhecimento da anatomia dos canais radiculares é essencial para o sucesso do tratamento endodôntico. Em virtude da sua complexidade e da morfologia da raiz mesiovestibular, o primeiro molar superior tem sido amplamente investigado, entretanto poucos estudos relatam a incidência do canal MV2 na clínica diária com profissionais com diferentes tempos de experiência. Objetivo: Avaliar clinicamente a incidência da localização do canal MV2 no tratamento endodôntico de primeiros molares superiores por acadêmicos de graduação, cirurgiões-dentistas especialistas ou não em endodontia, com diferentes tempos de formação na especialidade e que fazem uso ou não da microscopia operatória. Material e métodos: Foram avaliadas as fichas clínicas de 259 casos de tratamentos endodônticos de primeiros molares superiores realizados pelos participantes num período de 12 meses anterior à data da coleta de dados. Os participantes foram organizados da seguinte forma: grupo [A], alunos de graduação; grupo [B], profissionais não especialistas; e grupo [C], especialistas em endodontia. Estes também foram dispostos por tempo de formação na especialidade: menos ou mais de 10 anos (subgrupos [C1] e [C2]) e uso ou não do microscópio operatório (subgrupos [C3] e [C4]). Resultados: Com base na análise de todas as fichas de endodontia dos participantes da pesquisa, o resultado obtido foi de 54,05% de achados do canal MV2. Os resultados por grupo de participantes foram: 42,1% [A]; 40,62% [B]; 57,21% [C]. Os subgrupos de especialistas apresentaram os seguintes índices percentuais: 47,25% [C1]; 64,95% [C2]; 83,33% [C3] e 52,80% [C4]. Conclusão: Foi possível concluir que, quanto mais experiência clínica do profissional e uso da microscopia operatória, maior o índice (percentual) de localização, instrumentação e obturação do canal MV2 em primeiros molares superiores.

Com o constante avanço da Odontologia, novas alternativas estão sendo adotadas para o controle da doença periodontal (DP), incluindo a terapia fotodinâmica (PDT) como uma possível abordagem terapêutica. Objetivo: Investigar se o tratamento mecânico com raspagem e alisamento radicular (RAR) em pacientes com DP torna mais efetivo ou não quando associado com a PDT. Revisão da literatura: Realizou-se levantamento bibliográfico de 522 artigos na base de dados Pubmed; 19 foram selecionados, incluindo trabalhos em que os pacientes com periodontite crônica foram tratados com raspagem e alisamento radicular versus a PDT como adjuvante ao desbridamento mecânico da superfície radicular. Extraíram-se informações como: tipo de laser, comprimento de onda, potência de emissão, dosagem de energia, tempo de irradiação, concentração e tempo de aplicação do fotossensibilizador, além da observação dos parâmetros clínicos índice de sangramento gengival (ISG), profundidade de sondagem (PS) e nível de inserção clínica (NIC). Resultados: A raspagem associada a PDT foi mais efetiva e demonstrou melhora nos marcadores clínicos quando comparada apenas ao seu uso individual. Destaca-se que o protocolo comprimento de onda de 660 nm, potência de irradiação de 150 mW, densidade de energia de 60 J, concentração do azul de metileno 0,005% (AM), tempo de aplicação do AM de 5 min, tempo de irradiação 1 min apresentou os melhores resultados. Conclusão: Recomenda-se a execução de mais estudos para definir o melhor método de aplicação. No entanto o uso dessa tecnologia é promissor para o tratamento periodontal, além de ser um procedimento não invasivo, sem efeitos colaterais e de muitos benefícios.

O tratamento restaurador possui em seu favor diversos materiais que podem ser aplicados e que são constantemente aperfeiçoados na busca por uma melhor função e estética. Cada vez mais, os pacientes em busca pela melhor estética, principalmente em dentes anteriores, almejam tratamentos odontológicos com laminados cerâmicos. Entretanto, para esse tipo de procedimento, é necessária extrema atenção do cirurgião-dentista que vai realizá-lo. Em virtude da espessura reduzida e translucidez desses laminados, a seleção da cor é um desafio clínico complexo. Objetivo: Relatar e discutir dados presentes na literatura científica a respeito dos fatores que podem influenciar na cor final dos laminados cerâmicos, a fim de esclarecer ao clínico a melhor forma de obter o sucesso nesse tipo de tratamento e a satisfação do paciente. Revisão da literatura: Realizou-se uma busca de artigos nas seguintes bases de dados: PubMed, Google Scholar e Periódico Capes, utilizando os descritores: “ceramic veneers”, “resin cement”, “ceramic thickness” e “try in paste”. Resultados: A escolha apropriada da espessura da cerâmica, bem como da cor do agente cimentante, é importante para ótimos resultados estéticos. Os materiais restauradores sofrem diversas condições no ambiente bucal, envolvendo variações de temperatura, umidade frequente, corantes alimentares e influência da carga mecânica. Os laminados mais espessos são menos propensos a alterações de cor, uma vez que apresentam uma camada maior de material cerâmico entre o substrato dental e o cimento. Espessuras menores de cerâmica podem afetar a cor geral de uma restauração à medida que os valores de ∆E aumentam. Os cimentos com polimerização dupla sofrem mais alterações de cor, geralmente atribuídas à oxidação de aminas terciárias aromáticas presentes. Conclusão: A estabilidade de cor a longo prazo é essencial para alcançar o sucesso no tratamento com laminados cerâmicos, entretanto fatores como a espessura e a opacidade da cerâmica, o tipo de cimento resinoso e o método de polimerização, bem como fatores externos, podem afetar sua estética.

Authors: Felipe Eduardo Müller da Silva  , Luiz Paulo Valle Boschini da Silva  , Pedro Ivo Gualberto Malschitzky Alves da Silva
Published: June 2023

A zircônia translúcida de múltiplas camadas cromáticas em bloco é considerada uma biocerâmica com propriedades mecânicas, térmicas e de biocompatibilidade superiores em comparação às vitrocerâmicas e está indicada para a confecção de elementos protéticos estéticos monolíticos livres de metal, tanto para dentes anteriores quanto posteriores. Conclusão: Não há diferença entre as características adesivas das zircônias tetragonais opacas e as zircônias cúbicas translúcidas. Embora os cimentos convencionais não adesivos estejam indicados, sugere-se a utilização de cimentos resinosos adesivos duais associados ao monômero funcional MDP (10-metacriloiloxidecil di-hidrogênio fosfato) como o agente de união essencial para garantir a correta cimentação de todos os tipos de zircônias, pois melhoram a retenção e diminuem a infiltração marginal.

The inclusion of ethnomathematical perspectives into the mathematics education of indigenous student is often described as being beneficial. Drawing on weaving activities from West Amarasi society in Timor Island, Indonesia, this paper examines the results from the exploration of mathematical concepts that exist and are practiced in this society. This is a descriptive exploratory with ethnographic qualitative approach research. Data were collected in March 2022 through observations, interviews, and documentation. Some indigenous people from Merbaun Village, West Timor, in East Nusa Tenggara Province, Indonesia, were participants in this research. The results showed that there were several ethnomathematics characteristics in the weaving activities of the West Amarasi society: counting, locating, measuring, designing, explaining, the use of implication logic, and estimating. It was also found mathematics concepts and ways of thinking such as the concept of multiplication as repeated addition, parallel of straight lines, geometric shapes, reflection, rotation, sizes and units, and logical implication. This finding can be used as a source of mathematics learning by teachers, researchers or mathematics education practitioners not only those local in West Amarasi but also in other similar places around the world.

ABSTRACT:The power amplifier determines the output power of the audio amplifier and in this part there will be heat dissipation which is proportional to the output power of the amplifier. To overcome the problem of the audio amplifier, a class D amplifier was designed. The amplifier designed in this paper is Power Amplifier Class D Fixed Frequency Second Order that uses a fixed frequency triangular signal generator and an order 2 low-pass filter. In this case, a power amplifier is designed for a subwoofer that has a frequency range of 20 Hz – 200 Hz because in the audio frequency range it requires relatively large power. The design of the power amplifier and its measurement using the Circuit Maker simulator. The amplifier can work to amplify signals with a maximum amplitude of 1 Vp and a frequency range of 20 Hz – 200 Hz. At a frequency of 20 Hz the shape of the signal is not as good as that of the 200 Hz frequency signal because it is far from the cut-off frequency of the low - pass filter, which is designed to be 250 Hz.ABSTRAK:Penguat daya menentukan besarnya daya keluaran penguat audio dan pada bagian ini akan terjadi disipasi panas yang sebanding dengan besar daya keluaran penguat. Untuk mengatasi permasalahan penguat audio tersebut dirancanglah penguat kelas D. Penguat yang di rancang pada tulisan ini adalah Penguat Kelas D Frekuensi Tetap Orde Dua yang menggunakan pembangkit sinyal segitiga frekuensi tetap dan tapis pelewat frekuensi rendah orde 2. Dalam hal ini dirancang penguat daya untuk subwoofer yang mempunyai jangkauan frekuensi 20 Hz – 200 Hz karena pada jangkauan frekuensi audio tersebut memerlukan daya relatif besar. Perancangan penguat daya dan pengukurannya menggunakan simulator Circuit Maker.  Penguat dapat bekerja memperkuat sinyal dengan amplitudo maksimum 1 Vp dan jangkauan frekuensi 20 Hz – 200 Hz. Pada frekuensi 20 Hz bentuk sinyal tidak sebaik  bentuk sinyal frekuensi 200 Hz karena jauh dari frekuensi penggal tapis pelewat frekuensi rendah yaitu dirancang 250 Hz.

Experiments were done by using the direct test method and analyzing the obtained data to determine how much power was released and how much battery capacity was used to drive an electric motorcycle with variations of the driver's weight as much 60 Kg, 90 Kg, and 125 Kg and speed variations such as 10 Km/Hour, 20 Km/Hour, 30 Km/Hour, and 38 Km/Hour. The experimental results shows that the greater the weight and the speed of the motorcycle, the greater the power and capacity of the battery, so that could be concluded that the use of the battery on the motorcycle becomes more wasteful and the battery life will be shorter.ABSTRAKBahan Bakar Minyak (BBM) menjadi salah satu bahan bakar yang digunakan untuk menggerakkan kendaraan seperti sepeda motor. Penulis melakukan penelitian pada sepeda motor menggunakan energi listrik agar lebih ramah lingkungan. Dilakukan percobaan dengan metode uji coba langsung dan menganalisis data yang didapat untuk mengetahui seberapa besar daya yang dikeluarkan dan seberapa besar kapasitas baterai yang digunakan untuk menggerakkan sepeda motor listrik dengan variasi berat pengemudi yaitu 60 Kg, 90 Kg, dan 125 Kg dan variasi kecepatan yaitu 10 Km/Jam, 20 Km/Jam, 30 Km/Jam, dan 38 Km/Jam. Hasil percobaan menunjukkan semakin besar berat beban dan kecepatan pada sepeda motor, maka daya dan kapasitas baterai semakin besar dikeluarkan sehingga penggunaan baterai pada sepeda motor menjadi lebih boros dan ketahanan pada baterai semakin sebentar.

BACKGROUND

Multiple digital data sources can capture moment-to-moment information to advance a robust understanding of opioid use disorder (OUD) behavior, ultimately creating a digital phenotype for each patient. This information can lead to individualized interventions to improve treatment for OUD.

OBJECTIVE

The aim is to examine patient engagement with multiple digital phenotyping methods among patients receiving buprenorphine medication for OUD.

METHODS

The study enrolled 65 patients receiving buprenorphine for OUD between June 2020 and January 2021 from 4 addiction medicine programs in an integrated health care delivery system in Northern California. Ecological momentary assessment (EMA), sensor data, and social media data were collected by smartphone, smartwatch, and social media platforms over a 12-week period. Primary engagement outcomes were meeting measures of minimum phone carry (≥8 hours per day) and watch wear (≥18 hours per day) criteria, EMA response rates, social media consent rate, and data sparsity. Descriptive analyses, bivariate, and trend tests were performed.

RESULTS

The participants’ average age was 37 years, 47% of them were female, and 71% of them were White. On average, participants met phone carrying criteria on 94% of study days, met watch wearing criteria on 74% of days, and wore the watch to sleep on 77% of days. The mean EMA response rate was 70%, declining from 83% to 56% from week 1 to week 12. Among participants with social media accounts, 88% of them consented to providing data; of them, 55% of Facebook, 54% of Instagram, and 57% of Twitter participants provided data. The amount of social media data available varied widely across participants. No differences by age, sex, race, or ethnicity were observed for any outcomes.

CONCLUSIONS

To our knowledge, this is the first study to capture these 3 digital data sources in this clinical population. Our findings demonstrate that patients receiving buprenorphine treatment for OUD had generally high engagement with multiple digital phenotyping data sources, but this was more limited for the social media data.

Authors: Liu Jun , Shen Bo
Published: June 2023

BACKGROUND

Physical activity is a promising nonpharmacological therapy for individuals with autism spectrum disorder(ASD), but it is unclear the effects of web-based physical activity for them and their caregivers.

OBJECTIVE

To determine the effectiveness of web-based physical activity on individuals with ASD and their caregivers.

METHODS

We searched PubMed, Web of Science, Embase, The Cochrane Library, SPORTDiscus, and PsycInfo from inception to 31 January 2023 that examined the effectiveness of web-based physical activity in individuals with ASD or their caregivers. Two reviewers independently assessed methodological quality and extracted information from the included studies. The outcome measures used for individuals with ASD is physical activity level, for caregivers of children with ASD included mental health and perceptions and/or satisfaction regarding the web-based physical activity intervention.

RESULTS

A total of 10 articles with 158 individuals with ASD and 200 caregivers of them were included. Five studies reported positive intervention effect on physical activity level of individuals with ASD whereas one study found the changes were not significant and one study reported negative intervention effects. Large intervention effects were found for physical activity level (Hedges’ g=1.064, 95% CI [0.749,1.379], p=0.000) of individuals with ASD. Two studies reported the effects of web-based physical activity intervention on mental health in parents of children with ASD, all of these two studies reported a significantly greater improvement on anxiey level (Hedges’g=0.491, 95%CI [0.209, 0.772],p=0.001), depression level (Hedges’ g=0.534, 95%CI [0.251, 0.816],p=0.000) and stress level (Hedges’ g=0.68, 95%CI [0.212, 1.148],p=0.004) in the web-based physical activity group than in the control group. Six studies assessed how caregivers of individuals with ASD perceived the web-based physical activity intervention, overall, most caregivers of individuals with ASD were satisfied with this type of intervention.

CONCLUSIONS

The findings provided preliminary evidence for the web-based physical activities to increase the physical activity level of individuals with ASD and improving mental health in parents of children with ASD.
