Authors: Mahalisa Galih , Nurarminarahmah Nurarminarahmah
Published: January 2024

Air pollution is a global environmental problem that threatens human health and ecosystems. The Air Pollution Standards Index (APSI) is an important metric for measuring air quality and informing the public about the pollution level in an area. In the digital era, web-based applications have become an effective tool for providing real-time APSI information to the public. This research introduces an Air Pollution Standard Index (APSI) detection application based on the Flask model using the SVM (Support Vector Machine) algorithm to predict APSI. This application collects air quality data from various sensors distributed throughout the region and uses SVM (Support Vector Machine) to process the data. APSI prediction results are then presented to users via an easy-to-use web interface. The main advantage of this application is its ability to provide real-time APSI information so that users can take appropriate action according to the level of air pollution in their area. This application can help the public and environmental authorities proactively deal with air pollution and protect human and environmental health. APSI Prediction Accuracy: Through SVM model training, this application can predict the Air Pollution Standard Index (APSI) with sufficient accuracy. While there is potential to improve accuracy through more data collection and model updates, initial results are promising
Prediction of Narcissistic Behavior on Indonesian Twitter Using Machine Learning Methods
Authors: Ummah Izzatul
Published: January 2024

Social media's explosive expansion in recent years has changed people's behavior, leading to an increase in narcissistic tendencies. Arrogance, the need to flaunt one's accomplishments, the urge to get approval from others, and excessive dreams about success, power, intelligence, attractiveness, and other attributes are characteristics of narcissistic behavior. Social media has evolved into a platform for showcasing accomplishments, particularly for people with narcissistic tendencies. Moreover, narcissistic trait is one of the three characteristics of the dark triad personality type. Several research have demonstrated that a variety of machine learning techniques can be used to predict dark triad personality traits and narcissism from social media posts. As some studies have suggested, this narcissistic behavior can further increase the level of cyberbullying in social media, while also have strong correlation with the use of chatbot for academic cheating. This research aims to build a prediction model for behavioral symptoms of narcissism based on posts on Twitter in Indonesian language, using the natural language processing technique and several basic machine learning methods (Nearest Neighbors, Naïve Bayes, Decision Tree, and Support Vector Machine), and then compare the results. We concluded that SVM model achieved the best performance, with Accuracy = 0.72 and F1 Score = 0.725.

Published: January 2024

Most enterprises are now using information technology services as their assets to support business objectives. These kind of services are provided by internal service provider (inside enterprise) or external service provider (outside enterprise). To deliver quality information technology services, service provider (which from now on will be called “organization”) either internal or external, must have standard for service management system. At present, the standard that is recognized as best practice for service management system for organization is international standard ISO/IEC 20000:2011. The most important part of this international standard is the first part or ISO/IEC 20000-1:2011-Service Management System Requirement, because it contains 22 for organization processes as requirement to be implemented in organizational environment in order to build, manage and deliver quality service to customer. Assessing organization management processes is the first step to implement ISO/IEC 20000:2011 into the organization management processes. This assessment needs Process Assessment Model (PAM) as assessment instrument. PAM comprises two parts: Process Reference Model (PRM) and Measurement Framework (MF).  PRM is built by transforming the 22 process of ISO/IEC 20000-1:2011 and MF is based on ISO/IEC 33020. This assessment instrument was designed to assess the capability of service management process in Divisi Teknologi dan Sistem Informasi (Information Systems and Technology Division) as an internal organization of PT Pos Indonesia. The result of this assessment model can be proposed to improve the capability of service management system.

Authors: Yue Wu , Wenna Chen
Published: January 2024

This study investigates the correspondence between the spelling and pronunciation of English words, focusing on monosyllabic words. By applying the permutation and combination methods and the maximum onset principle, we systematically analyze the various forms of monosyllabic words preceding with zero consonant, single consonant, double consonants, and three consonants before vowels. The systematic analysis of vowel replacements (E, I, O, U) within C-V combinations unveils distinct patterns for long and short vowels, diphthongs, triphthongs and r-controlled vowels. The findings reveal the underlying regularities that impact the pronunciation of English words. The study is designed to cultivate phonological awareness in second language acquisition, paving the way for in-depth research on the relationship between the spelling and pronunciation of multi-syllabic words in English through the (((C)C) C) V((((C)C) C) C) model.

MODERN TRENDS OF THE JORDANIAN LEGISLATOR REGARDING THE ISSUE OF DEBTOR IMPRISONMENT
Authors: H. Al-Azzam Amjad
Published: January 2024

Following the issuance of Defense Order No. 28 of 2021 in light of the Corona pandemic (to postpone the implementation of decisions to imprison the debtor issued pursuant to the provisions of the Implementation Law), a media storm erupted in the media and social media, inciting Jordanian public opinion against imprisonment of the debtor, prompting the Jordanian legislator to make amendments to The implementation law is one of the most important; Ruling that it is not permissible to imprison the debtor if he is unable to fulfill a contractual obligation, with the exception of real estate leases and work contracts. The problem of the research lies in the legislator’s bias towards the debtor at the expense of the creditor, who in turn will refrain from granting credit and forward transactions, which negatively affects the course of civil and commercial transactions. The study followed the descriptive and analytical approach to the texts of the implementation law and the rulings of the Jordanian judiciary. This study concluded that the debtor imprisonment system contradicts the Jordanian legislator’s approach to emptying prisons of inmates who do not pose a criminal threat to society in order to avoid disrupting them from work and production. The study recommended canceling the debtor's imprisonment on the condition of adopting the civil death penalty system, which represents the paralysis of financial, administrative, and governmental transactions of the procrastinating debtor.
Performance Analysis of 8 × 112 Gbps (0.896 Tbps) WDM ROF Link Using 32 QAM - OFDM Modulation Scheme for Achieving Extended Range
Authors: Prajapati Jayeshkumar C. , Maradia K. G.
Published: January 2024

We propose an advanced optical transport system utilizing higher order modulation formats and coherent detection. Our innovation introduces an 8 × 112 Gbps wavelength division multiplexing – radio over fiber (WDM ROF) link using a 32 quadrature amplitude modulation-orthogonal frequency division (QAM-OFDM) modulation scheme, capable for extending its reach. Our proposed research stands out from existing studies due to its distinctive use of the 32-QAM format and a 112 Gbps data rate per channel, especially when considering a channel span of 3000 km. Our analysis covers WDM-ROF link systems, including a preoptical amplifier within the link, one optical amplifier outside the channel loop span, and one within the loop span, representing distinct scenarios. We operated optical amplifiers in the gain-controlled mode. Remarkably, exclusive of employing precise dispersion or nonlinearity improvement techniques, carried out simulations reveal optimal transmission distance for our anticipated system having considered specification parameters is 3000 Km. We conducted extensive simulations to assess the system performance in terms of quality factor (Q-factor), estimated symbol error (ESE), and error vector magnitude (EVM) over link spans ranging from 1000 to 15,000 km.

Authors: Fonseca Mayra Rachel de Aguiar , Maia Aline Cabral Vieira Mendonça , Barros Lívia de Melo , Silva Renata Santos , Santos Gleice Kelly Nascimento , Oliveira Leonita Chagas de
Published: January 2024

A presente pesquisa objetivou compreender quais são os significados atribuídos por acadêmicos na área da saúde ao processo da morte e do morrer. Utilizou-se do método qualitativo de corte transversal e, como instrumento mediador da coleta dos dados, a entrevista semiestruturada. Participaram da pesquisa 24 universitários de diferentes cursos, sendo eles: Psicologia (6), Fisioterapia (6), Medicina (6) e Enfermagem (6) de uma instituição de ensino superior do Nordeste brasileiro. Desenvolveu-se a análise textual discursiva. Foram analisadas três categorias temáticas que emergiram dos dados coletados: significados e conceitos da morte e do morrer; desafios e sentimentos que emergem diante da morte e do morrer; e a temática da morte e do morrer nos cursos de graduação. Entre os resultados destaca-se que os relatos apresentados demonstraram uma diversidade de compreensão da morte entre os acadêmicos, sendo o contexto social, histórico e cultural um fator de relevância na influência desses entendimentos. A separação, a continuidade da vida e os entendimentos espiritualistas foram alguns dos conceitos e significados da morte explicitados pelos acadêmicos nesta pesquisa. Os discursos exemplificaram que lidar com a morte gera uma desordem e uma confusão e que podem levar à negação dela como uma maneira de se afastar de experiências dolorosas. Além disso, expressaram a presença da naturalização da morte na construção acadêmica do profissional da saúde, direcionada à necessidade de curar o paciente e no prolongamento da vida. Infere-se que a formação acadêmica se mostra insuficiente para a elaboração desse processo de enfrentamento da morte e do morrer. Concluiu-se que a elaboração dos significados sobre os processos da morte e do morrer permite aos futuros profissionais o desenvolvimento de uma atuação qualificada, ética e humana, compreendendo as suas capacidades de propiciar ao paciente um processo de finitude humanizado.
Garden Cities in Theory and Practice
Authors: Sennett A.R.
Published: January 2024

Garden cities sought to combine the best of town and country living to provide healthy vibrant communities on a human scale: affordable housing for all classes in tree-lined streets with well-tended gardens, jobs within easy commuting distances, integrated transport, all surrounded by a green belt to prevent urban sprawl. The first examples were built in England in the early years of the twentieth century but the idea soon caught on internationally, with garden cities being planned and built in the USA, Australia, Germany and Japan amongst countries. Alfred Sennett's little known classic work offers one of the most comprehensive accounts of garden cities. Its two volumes cover not only the history and idea of the garden city but are unique in their encycopaedic coverage of the practicalities of the garden city. Among the topics covered are transport, building materials, agriculture, self-cleansing streets, rolling roofs, as well as the sociological aspects. He draws comparisons with cities of the ancient world but also with cities in other countries.

Objetivos: Identificar e mapear a literatura científica existente sobre as intervenções de enfermagem no âmbito da promoção da literacia em saúde sobre hábitos de sono saudáveis, das crianças dos 6 aos 12 anos, em contexto de saúde escolar. Material e Métodos: Foi realizada uma revisão scoping que seguiu a metodologia recomendada pelo Joanna Briggs Institute. A pesquisa foi realizada entre 25 e 30 de maio de 2023, nas bases de dados CINAHL e MEDLINE da plataforma EBSCOhost e na PubMed, sendo utilizados os descritores: crianças, sono, hábitos de sono, enfermagem e escola, por meio do operador booleano AND. Foram considerados como critérios de inclusão o acesso a texto completo, publicações com friso cronológico até 5 anos, artigos em que a idade das crianças se situa entre os 6 e os 12 anos. Resultados: A pesquisa resultou em sete estudos: 2 da Turquia, 1 do Japão, 1 da Austrália, 1 do Irão, 1 da Finlândia e 1 de Portugal. Os resultados evidenciaram que os problemas de sono são frequentes nas crianças, podendo afetar a sua saúde física e mental e que a enfermagem em contexto escolar é fundamental no desenvolvimento de programas para melhorar o sono das crianças, com o envolvimento da comunidade escolar (Shamsaei et al., 2019, Silva et al, 2018; Top et al., 2022). Conclusões: Todos os estudos destacam a importância do sono no crescimento e desenvolvimento das crianças e salientam a relevância da promoção da literacia em saúde, para capacitar a comunidade escolar (crianças, famílias, professores). Neste sentido é destacado o papel da enfermagem comunitária em contexto escolar, uma vez que em muito pode contribuir para a capacitação da comunidade escolar, através de intervenções promotoras de hábitos de sono saudáveis.

Introdução: É amplamente reconhecido que as contrações musculares excêntricas quando repetidas com volume e intensidade consideráveis podem induzir dano ao músculo esquelético. No entanto, há pouco conhecimento sobre o impacto das contrações excêntricas em estruturas não musculares como o nervo periférico. Objetivos: Revelar os efeitos imediatos (isto é, <2 horas) e a curto prazo (isto é, <10 dias) das contrações musculares excêntricas nas propriedades estruturais, biomecânicas, fisiológicas e funcionais dos nervos periféricos, tanto de estudos em animais quanto em humanos. Material e Métodos: Quatro bases de dados (ou seja, Pubmed, Science Direct, PEDro e Cochrane) foram utilizadas para a pesquisa de estudos que envolvessem contrações excêntricas dos músculos dos membros superiores ou inferiores e resultados relacionados aos efeitos imediatos e/ou a curto prazo destas na estrutura, propriedades fisiológicas, biomecânicas e funcionais dos nervos periféricos. A qualidade metodológica dos estudos humanos foi avaliada com recurso à escala Risk Of Bias in Non-randomised Studies of Interventions (ROBINS-I) e SYRCLE’s Risk of Bias tool para estudos em animais. Resultados: De um total de 2415 artigos, 2 estudos em humanos e 2 em animais cumpriram os critérios de inclusão. A avaliação do risco de viés para os estudos em animais foi divergente para todos os itens em relação ao viés de seleção. Os estudos em humanos revelaram uma qualidade metodológica geral baixa a moderada. Foram encontradas alterações sugestivas de lesão do nervo periférico associada ao exercício. Observou-se redução na espessura da bainha de mielina e diâmetro da fibra (Kouzaki et al., 2016), diminuição da velocidade de condução nervosa sensorial e motora (Ochi et al., 2021). O nível de proteína zero reduziu, enquanto a concentração de macrófagos e tropomiosina quinase C aumentaram (Lee et al., 2014). Diferenças temporais foram encontradas entre estudos em humanos e animais. Além disso, nos estudos em animais, os efeitos foram de maior magnitude quando as contrações excêntricas eram realizadas a uma maior velocidade. Conclusões: As contrações excêntricas aparentemente alteram as propriedades estruturais, morfológicas, funcionais e fisiológicas dos nervos periféricos, o que provavelmente pode ser interpretado como dano neural.
Influência da funcionalidade corporal no risco de queda em idosos institucionalizados
Authors: Gagulic Sandra , Soares Bárbara
Published: January 2024

Introdução: O desenvolvimento de uma imagem corporal negativa ou positiva depende de vários fatores. Investigações recentes defendem que é importante a aceitação do corpo para além da aparência e devem ser aprofundadas outras dimensões como a funcionalidade corporal. A funcionalidade corporal envolve um foco nas cognições e sentimentos positivos em relação às capacidades corporais. Objetivos: verificar a relação entre a funcionalidade corporal e o risco de queda em idosos institucionalizados. Material e Métodos: Estudo realizado com idosos institucionalizados na cidade de Viseu. Critérios de inclusão: score > 20 pontos no Mini Mental State Examination; consentimento livre e informado; capacidade de deambular com e sem auxiliar de marcha. Instrumentos de recolha de dados: Questionário sociodemográfico e clínico; escala Functionality Appreciation Scale (funcionalidade corporal); teste Timed Up&Go (risco de queda). Estatística descritiva e inferencial não paramétrica com nível de significância < 0.05. Resultados: 31 participantes com idades entre 63 e 95 anos, a média de 82,81±7,93 anos. 56,3% referem que têm uma saúde Razoável, 28,1% consideram que têm uma saúde Boa. 40,6% referiu que já caiu, com um mínimo e um máximo a oscilarem entre 1 a 6 quedas (1,95±143). Nas escalas FAS: “Valorizo o meu corpo por aquilo que ele é capaz de fazer (3.5±1.27); “Sou grato/a pela saúde do meu corpo (3.72±0.99); “Valorizo o facto de o meu corpo me permitir comunicar e interagir com os outros” (4±1.16); “Reconheço e aprecio quando o meu corpo se sente bem e/ou relaxado” (3.38±0.9); “Sou grato/a pelo facto de o meu corpo me permitir participar em atividades que eu aprecio ou considero importantes” (3.56±1.01); (3.34±1,06)“Sinto que o meu corpo faz tanto por mim” (3.34±1,06); “Respeito o meu corpo pelas funções que ele desempenha” (3.53±0.91). Na correlação entre o risco de queda e o score total da FAS existe uma correlação estatisticamente significativa (-0.982). Conclusões. A avaliação da funcionalidade corporal é uma variável importante na avaliação do fisioterapeuta, de forma a implementar diferentes estratégias em termos de intervenção ao nível do risco de quedas. Recomenda-se que o estudo seja realizado numa amostra de maior dimensão e em diferentes contextos geográficos.

Published: January 2024

Aceh Jaya is one of the potential habitats and migration areas for various types of sharks because of its geographical location directly facing the Indian Ocean. This research was conducted to contribute to shark data collection through molecular genetic approaches. The objectives of this research include: conducting molecular identification of the types of sharks found; Analyzing the kinship relationships of the types of sharks found, and determining the conservation status of the types of sharks found. The results of the research that has been carried out found 6 individuals of sharks and 4 individuals of rays from 6 species of IU and 2 species of rays landed at Rigaih Fishing Port. The results of molecular identification show similarities with morphological identification results with an average percentage of per. ident reaching more than 95% and query cover more than 85%. The results of phylogenetic analysis show that the types of Sphyrna lewini and Rhynchobatus australiae have plesiomorphic characters. Based on references to the IUCN Red List standard unit, it shows that there are 3 species of sharks landed at Rigaih Fishing Port with critical status (CR), 4 species with vulnerable status (VU), and one species with near extinction status (NT). This result is an important finding where so far the status of shark populations landed and traded at Rigaih Fishing Port is unknown and has not been recorded statistically.

Increasing the productivity of aquaculture must be supported by feed input; however, in addition to being expensive, this input can produce nutrient waste. Therefore, finding inexpensive alternative forms of feed with environmentally friendly cultivation practices is important to do simultaneously. This study aimed to determine the effect of variations in the form of maggot feed on the Nutrient Reduction Efficiency (NRE) of freshwater clams (Pilsbryoconcha exilis) in an integrated multitrophic aquaculture (IMTA) system. This 28 day experiment used a Completely Randomized Design (CRD) with four types of feed treatments (live maggots, dried maggots, supplemented maggots, and commercial feed (control). A total of 10 individuals of freshwater clams combined with 10 tilapia fish and freshwater lobsters respectively, as well as 4 clumps of rice were floated in a rearing tank with a volume of 50 L of fresh water. The results of analysis of variance showed that variation in feed had a significant effect (P<0.05) on the NRE of ammonia (NH3), nitrate (NO3), phosphate (PO4) by freshwater clams (Pilsbryoconcha exilis). Tukey HSD test results indicated that the highest NRE of ammonia (NH3) in live maggots feed was significantly different (P<0.05) from dried maggot feed and supplemented maggots, but not significantly different (P>0.05) from commercial feed. NRE nitrate (NO3) was significantly different in each treatment. Meanwhile, the highest NRE phosphate (PO4) in live maggots feed was not significantly different (P>0.05) from dried maggots, but was significantly different (P<0.05) from supplemented maggots and commercial feed.
