ABSTRACT
Noise induce hearing loss (NIHL) is often found in students. The advancement of electronic devices along with the ease of accessing the internet and social media has caused students to often use personal listening devices such as headphones/earphones to access information from these electronic devices. Early identification of hearing loss and appropriate intervention have been shown to prevent such consequences. The purpose of this activity was to educate noise induce hearing loss (NIHL) and to know early on the ear and hearing condition of students and provided intervention and management as needed. The method in this activity was planned to be carried out through stages in accordance with the HIRARC (Hazard Identification, Risk Assessment, and Risk Control) control instructions. The results of this activity obtained the hearing of 147 students within normal limits, 31 students with cerumen, 7 Otitis Externa students, 3 OMSK students, and 4 students with suspect of noise induce hearing loss. Students who were suspected of suffering from hearing loss due to noise were recommended to Dr. Moewardi Surakarta Hospital for further examination and management.

Published: February 2024

This research endeavours to elucidate the notable disparities in Problem-Solving Skills (PSS) when employing the Flipped Learning Model with a STEM Approach (FLM-SA) in contrast to Routine Learning, contingent upon attitude categories. The study harnesses a quantitative methodology with a quasi-experimental design. A sample size of 210 students is utilised, chosen via cluster random sampling. The instruments for data collection comprise: 1) an attitude questionnaire; 2) problem-solving tests; and 3) an observation sheet for the execution of the learning process. The techniques for data analysis employed are both parametric and non-parametric tests. The findings unveil a significant discrepancy in the students' Problem-Solving Skills based on attitude category between the control group, post the implementation of routine e-learning, and the treatment group, post the utilisation of the FLM-SA Module. Students possessing a Medium Attitude Category in the experimental class exhibit superior problem-solving skills compared to the control class. In contrast, students with Low and High Attitude Categories do not demonstrate a significant difference between the control and experimental classes. These findings underscore the significance of differentiated learning by implementing Teaching at the Right Level. Ideally, teachers should conduct an initial diagnostic assessment to ascertain students' initial attitudes or abilities

Published: February 2024

Based on the modification of the infectious disease model, taking into account diffusion disturbances and logistic dynamics of immunological cells, separate approaches to the diffusion scattering parameters identification for different types of functional dependence of diffusion coefficients and given redefinition conditions are proposed. A special step-by-step procedure for numerically asymptotic approximation of the solution to the corresponding singularly perturbed model problem with a delay has been improved. The results of computer experiments on identifying the unknown diffusion scattering parameters are presented. It is noted that the identification and application of variable diffusion coefficients will provide a more accurate prediction of the dynamics of an infectious disease, which is significant in decision-making regarding the use of various medical procedures.

Published: February 2024

In recent years, social media platforms have become powerful data collection tools to improve user experience. The vast amount of data generated through social media provides a unique opportunity to develop innovative recommendation systems. This article analyzes the application of data mining methods for social networks in the context of effective recommendation systems, focusing on three key methodologies: sentiment analysis (SA), topic modeling (TM) and social network analysis (SNA), highlighting their positive features. SA allows the system to tailor recommendations based on sentiment analysis, offering users items that match their expressed emotions. Experiments show significant improvements in recommendation accuracy when sentiment data is integrated. TM allows the system to understand the main concerns of users by identifying dominant themes, thereby providing personalized recommendations and staying abreast of evolving trends. At the same time, AFM identifies influential users and communities, increasing relevance and awareness of system elements. The article highlights the enormous potential of social networks for the development of effective, personalized recommendation systems. Using sentiment analysis and topic modeling, these systems can provide personalized and relevant recommendations based on public sentiment, trending topics, and social network dynamics.

To form a knowledge base is complicated problem traditionally. There are a lot kind of objects that are possibly used for forming a knowledge base. These objects may have different structures, formats, ways of data representation, languages. The simple conjunction is not effective and suitable. In general case the knowledge base has got as an unordered knowledge base. There are uncategorized documents in such unordered knowledge base with different formats that causes the special and particular approaches for recognition, systematization and next processing of some textual information. It’s why the complexes of automation for all stages of processing are complicated. Naturally it is a restriction for some kind of the decision support system, especially in military or other applications with key time factor (to get a quick and exact access to the knowledge base in decision support system). So, we analyzed the mentioned restrictions and conditions for forming a knowledge base in the paper. We depicted that the ontology of knowledge base both in general and specific cases includes such operations as data collection, data regularization, extraction of knowledge, data conversion for matrix representation, data language processing, tokenization, output generation for a request and machine learning for information-retrieval system optimization. There is a model of information-retrieval system for knowledge base with widely- used PDF-documents that is proposed in the paper. We made the model using open learned transformer and Llama Index framework to decrease the time demands in the information-retrieval system. Also, we included the language processing models for translation the specific textual information from Ukrainian into English and back. As a result, we got the method and the model for processing the textual information from PDF-document in Ukrainian that could be effective in any decision support system. The method ensures the reading, tokenization, translation, analysis and retrieve generation of the data in Ukrainian. The model showed its simple, stable and exact estimations, but there are also some disadvantages, high time installation/compilation and little language defaults are some of them. The results encourage us to continue the research and to get the statistics set to analyze the model estimation more properly.

Published: February 2024

This study analyzes the impact of management approach on the economic efficiency of local public facilities, focusing particularly on island and non-island regions. Particularly, the research explores how the economic efficiency of public facility management in island regions may differ from other regions, taking into account the unique characteristics of island areas. The distinctive features of island regions, such as limited resource accessibility, create a responsibility for the government to provide essential services to residents and tourists. Consequently, the management methods of public facilities become more crucial in island regions compared to non-island areas, posing a significant challenge in terms of economic sustainability. Additionally, the low population in island regions imposes limitations on generating internal revenue, which can hinder the sustainable operation of public facilities. Furthermore, island regions possess unique historical and cultural aspects that influence the management styles of public facilities, requiring an integrated approach that combines local characteristics and expertise. Empirical analysis results reveal that, in terms of profit after deducting costs, direct management facilities are relatively advantageous in island regions compared to non-island areas. As the first study to demonstrate how the economic efficiency of local public facilities may differ based on the regional uniqueness of islands, this research emphasizes the policy necessity of considering regional characteristics, such as those found in island areas, when deciding on the management methods of public facilities.

Road traffic in urban areas is highly prone to the occurrence of road crashes, while crash severity level differs at the city level and in relation to the leading cause. In the case of urban sustainable environments, strategic planning and development measures have been implemented for safer mobility by effective traffic management and road user education. Still, in crowded cities, where mobility and transit traffic are major factors, road crashes are the antithesis of road safety and they occur in simple or complex circumstances mostly related to road users and road infrastructure. The aim of this study was to define the severity level of road traffic crashes in the cities of Romania during the reference period 2008 - 2019, before the COVID-19 pandemic, while highlighting the leading causes of road crashes in urban areas that determine their highest occurrence and severity level. Official crash data records provided by the general Directorate of the Romanian Police were employed. The general severity degree of road crashes was calculated, particularly in relation to the first five leading causes, and cities were ranked accordingly. Results are rendered at the local level, for all 319 cities and towns in Romania, by the five leading causes and by severity level, comparatively for the years 2008 and 2019. Synthetically, we pinpoint the Romanian cities that are most affected by this phenomenon. This could help local and national decision-makers direct their focus towards mitigating the negative effects of the frequent crash triggering factors, decrease road crash severity levels and create customized measures for better traffic management and increased road safety at the local level.

Authors: Leite Ana Carolina da Silveira
Published: February 2024

A partir das perspectivas teórico-metodológicas da História Social da Cultura Escrita, este texto visa a analisar e discutir quatorze cartas de chamada, com assinaturas coletivas, escritas por imigrantes portugueses, homens e/ou mulheres, entre 1896 e 1929. Para tanto, pretende-se enfatizar a importância do diálogo entre áreas distintas e complementares das ciências humanas por meio do cruzamento de perspectivas: a mobilização de micro histórias, a Linguística, a História Cultural e a Paleografia, retirando, assim, sujeitos históricos do esquecimento, dando voz a seus escritos e possibilitando, então, outros modos de se compreender a história da penetração da língua portuguesa no Brasil, destacando aspectos que podem revisar ou confirmar questões consolidadas pelas grandes narrativas. Afinal, o que se sabe sobre o Brasil e a escrita de imigrantes nesse período? Como eram essas cartas? Quem as escrevia e por quê? Para quem as escrevia? Quem assinava também escrevia? As respostas a estas questões serão apresentadas e, assim como os caminhos para chegar até elas, discutidas, com o intuito de contribuir para a construção de uma História Social da Cultura Escrita no Brasil através da epistolografia.
Filologia e lexicologia: estudo léxico-semântico de um manuscrito do século XVIII
Authors: Trindade Lima Santos Bruna , Lose Alicia Duhá
Published: February 2024

As línguas, inevitavelmente, refletem as influências dos elementos sócio-históricos, geográficos e culturais que estão relacionados à história dos seus falantes. O léxico, portanto, é o lugar onde são percebidas essas influências e marcadas as definições identitárias, como é o caso do Brasil e principalmente do português brasileiro (doravante PB), nascido do contato entre europeus, indígenas e africanos. Nesse sentido, podemos notar, ainda hoje, os empréstimos lexicais advindos das línguas indígenas e africanas, além da língua dos imigrantes, e que enriqueceram a língua portuguesa em solo brasileiro. Assim, neste artigo, com base nos princípios da Lexicologia e no corpus retirado da edição semidiplomática do documento Plano Sobre a Civilização dos Índios do Brasil, investigou-se a contribuição indígena no repertório lexical utilizado pelo autor do documento, o militar Domingos Muniz Barreto, de forma a analisar a influência indígena no português brasileiro do século XVIII, a instauração de uma ortografia para palavras indígenas e o vocabulário indígena utilizado nos capítulos “Índios Mansos e Índios Bravos”, do mesmo documento. A metodologia baseou-se em Queiroz (2012). Concluiu-se que o repertório lexical de Domingos e o uso do vocabulárioindígena revelam as pistas para uma gramaticização das línguas indígenas, através da grafia em língua portuguesa, e que isso favoreceu a incorporação das mesmas no próprio PB.
Linguistic Contact and Portuguese-to-Spanish Document Translation During the Iberian Union
Authors: Procópio Eliabe dos Santos , Gonçalves Rosineide Lima
Published: February 2024

The present paper discusses document translation and analyzes the translation from Portuguese to Spanish of a report of the Council of Portugal, which describes the political-administrative situation of the Moluccas Islands. The concepts of bilingualism and diglossia (FISHMAN, 1967) are used to discuss the colonial translation scenario, and the taxonomic framework provided by Barbosa (2004) supports the translation analysis. The main research tools are the selection and editing of manuscripts, and the classification of translation procedures. Results indicate the historical study of document translation between Portuguese and Spanish as a new research field, mainly involving contact between languages; the tendency towards literality as the main feature of Iberian Union (1580-1640) administrative translation, as these are technical documents; punctual translator interference, with instances of source-text omission and rewriting; and the possible comparison between document translation in Asian and American Portuguese colonies.
Um gradiente da habilidade com a escrita: cartas privadas no contexto da imigração portuguesa para o Brasil no século XX
Authors: Cardoso Rafael Rodrigues da Silva , Lopes Célia Regina dos Santos
Published: February 2024

O artigo apresenta uma proposta para a análise do grau de habilidade com a escrita de redatores de 99 cartas privadas escritas no contexto da imigração portuguesa para o Brasil de 1948 a 1960. Baseados em Barbosa, 2017 e Santiago, 2019, a análise é feita a partir do levantamento de desvios gráficos em relação ao referencial modelar escolhido, separando-se os redatores em um gradiente de habilidade. A proposta permitiu categorizar o corpus de cartas em função de critérios objetivos, evidenciando que os remetentes produziram textos mais ou menos influenciados pelas práticas correntes da escrita. Ademais, alguns desvios ocorreram apenas nos remetentes de menor grau de habilidade e são possivelmente “mais graves” ou indicativos de uma baixa habilidade com a escrita do que aqueles observados nos remetentes mais hábeis.

ΚΑΙ ΣΥ ΤΕΚΝΟΝ. A correspondência helénica de Brutvs, assassino de César: Primeira tradução em língua portuguesa; reflexões; bibliografia
Authors: Troca Pereira Reina Marisol
Published: February 2024

Definir a autenticidade das 70 epístolas imputadas ao romano Marco Júnio Bruto é uma questão insolvente. A redação epistolar helénica de foro institucional reunida em vários manuscritos ela revela um estilo discursivo elogiado por muitos. Entre alegados envios e supostas respostas a ordens, solicitações, ameaças, traições, conselhos, desculpas, evidenciam-se amizades e desafetos diplomáticos, escolhas políticas, estratégias bélicas, recursos, alianças de um complexo cenário de povos com os quais o tiranóctono se subscreve. E mais não fosse, uma coloração sentenciosa marcada com tiradas gnómicas perpassa o epistolário aqui vertido pela primeira vez na íntegra em idioma luso. Compete, ao leitor atual ponderar além de uma suposta historicidade dos escritos ou integrá-los total ou parcialmente no foro ficcional enquanto exercícios retóricos de cariz didático, quiçá até panfletário, de datação incerta.

Published: February 2024

Abstract. This study aims to explore the collegial collective relationship between BPK members and follow up on the results of the examination. The approach used is the descriptive qualitative research method. Data were collected through interviews with 8 auditors from the DIY Representative BPK. The interview was conducted to explore the perception of the BPK auditors regarding the collegial collective relationship between members and the follow-up to the results of the examination. The results of this study indicate that there is a collegial collective relationship between BPK members. Since the existence of a collegial collective relationship between BPK members, there is no longer domination of the BPK chairman in deciding a policy. Policies that are strategic and have a national impact will be decided jointly by all members of the BPK (team 9 or agency members). If consensus is not reached, a vote is held to seek the most votes. Regarding the follow-up examination, when the auditor and the review team find any deviations, the follow-up is carried out by giving a kind of management letter to the auditee. BPK's findings must be followed up by returning the amount of money found. If the finding exceeds Rp10,000,000 must be reported in the LHP.

Published: February 2024

Aluminum is widely used in the industrial world, usually, the connection of aluminum often uses the rivet method and Tungsten Inert Gas (TIG) welding. Many welding methods can be used for joining aluminum, but the Friction Stir Welding method is the most recommended method because the process is simple and does not pose a health hazard. This research was conducted to determine the contribution of the Friction Stir Welding (FSW) process parameter to the depth of surface defects using a hexagonal pin geometric tool. Welding material uses AA6061-T651 aluminum and uses 4 parameters: tool speed, welding speed, concave shoulder angle, and tool tilt angle. In this process, the Taguchi method is used to study the effect of parameters with a predetermined process variation. From the results of ANOVA with signal to noise, more minor is better, we get a significant factor in the depth of surface defects. The results obtained are surface defects close to 0 mm or parallel to the specimen surface, in specimen 16 with a tool slope parameter of 2°, a tool rotation speed of 3022 rpm, welding speed of 60 mm/m, and a concave shoulder angle of 11°.

El régimen jurídico de las alteraciones de los grupos políticos locales
Authors: Pavel Eduard-Valentin
Published: February 2024

Objetivos: el presente artículo tiene por objeto deslindar el régimen jurídico de las alteraciones de los grupos políticos locales. Dicho de otra manera, se ha pretendido analizar en profundidad, a la luz del art. 73.3 de la LBRL, las figuras de la adscripción y no adscripción a los grupos políticos, dado que se prevén de forma inacabada las vicisitudes sustantivas y procedimentales de la alteración de estos. Metodología: la metodología utilizada es la típica del derecho: el uso de la normativa, jurisprudencia, doctrina consultiva y la doctrina científica. Resultados: se han establecido las bases del encaje dogmático y cauce procedimental aplicable a la no adscripción (principal mecanismo forzoso de alteración del grupo político local), teniendo particularmente en consideración los motivos de la existencia de esta figura, así como la intervención de una pluralidad de sujetos en las decisiones sobre la composición de los grupos. Conclusiones: nuestro ordenamiento jurídico no prevé un régimen jurídico completo de no adscripción o, más ampliamente dicho, alteración del grupo político local, ni en los aspectos sustantivos para su producción ni tampoco sobre el iter procedimental que seguir para su acuerdo, necesitándose para ello la intervención del legislador.
Türkiye'de Phillips Eğrisinin Geçerliliği: Çoklu Yapısal Kırılmalara Dayalı Ampirik Bulgular
Authors: KARTAL Gökhan
Published: February 2024

Bu çalışmada Türkiye'de kısa ve uzun vadede Phillips eğrisinin geçerliliğini, 1960 ile 2022 yılları arasındaki enflasyon ve işsizlik verilerini içeren bir veri seti ile çoklu yapısal kırılmaları dikkate alan Carrion-i-Silvestre vd. (2009) çoklu yapısal kırılmalı birim kök testi, Maki (2012) çoklu yapısal kırılmalı eşbütünleşme testi ve Newey-West HAC Tahmincisi kullanılarak incelenmektedir. Bu çalışma, değişkenler arasındaki ilişkinin sapmasız bir şekilde elde edilebilmesi için hem birim kök analizinde hem de eş bütünleşme analizinde yapısal kırılmaları dikkate alan az sayıdaki çalışma arasında yer alması, aynı zamanda diğer çalışmalardan farklı olarak 1960’ları kapsayacak şekilde en geniş ve en güncel veri setiyle değişkenler arasındaki ilişkiyi ampirik olarak incelemesi bakımından literatüre önemli bir katkı sağlamayı amaçlamaktadır. Bulgular, Türkiye'de uzun vadede Phillips Eğrisinin geçerli olmadığını, ancak kısa vadede önemli bir ters ilişki olduğunu (enflasyon ile işsizlik arasında trade-off) göstermektedir. Kısa dönem sonuçları işsizlik oranındaki 1 birimlik artışın TÜFE’yi 0,49 düşürdüğünü göstermektedir. Bu sonuçlar, Monetarist ve Yeni Keynesyen görüşlerle uyumlu olup, politika yapıcılar için önemli ipuçları sunmaktadır. Bu doğrultuda, çalışmada Yeni Keynesyen ve Monetarist ekollerinin savunduğu görüşler ekseninde politika yapıcılara bir dizi para ve maliye politikası önerileri sunulmaktadır.
Muhasebe Eğitiminde Dijital Uygulamaların Hile Denetimine Katkıları: Üniversite Müfredatlarında Bir Araştırma

Published: February 2024

Dijital çağda tüm dünyayla beraber muhasebe mesleğinin de önemli ölçüde değişeceği öngörülmekte; dijital uygulamaların muhasebede kendine şimdiden daha geniş bir uygulama alanı bulacağı düşünülmektedir. Özellikle hile tespiti konusunda teknolojiyle uyumlu dijital uygulamaların, geleneksel yöntemlere kıyasla daha başarılı olması; muhasebe hilelerinin tespitinde ve önlenmesinde dijital uygulamalara daha sık bir biçimde başvurulmasına neden olmaktadır. Muhasebe alanında hile denetiminde görev yapacak olan meslek mensuplarının, bilişim altyapıları, bilgi teknolojileri ve veri analitiğine olan hakimiyeti olası muhasebe hile ve usulsüzlüklerinin önüne geçilebilmesi adına oldukça önemlidir. Bu nedenle hile denetiminde rol alacak mezunların çeşitli veri analitiği yöntemlerinden aktif bir şekilde yararlanması gerekmektedir. Dolayısıyla, üniversite müfredatlarına hile denetiminde kullanılacak becerilerin dijital çağın gerektirdiği şekilde entegre edilmesi zorunlu hale gelmektedir. Üniversitelerde konuya ilişkin dijital çağa uyumlu müfredatların oluşturulması, güncel müfredata veri analitiği yöntemlerinin ve diğer dijital uygulamalarının eklenmesi, öğrencilerin mesleki alanlarda kullanabilecekleri dijital yetkinliklere henüz mezun olmadan sahip olabilmelerini sağlayacaktır. Söz konusu amaç doğrultusunda yapılan bu çalışmada, Türkiye’de işletme eğitimi veren üniversitelerin hile denetimine katkı sağlayacak uygulamaya dönük yeterlilikleri araştırılmıştır. Çalışmada üniversitelerin güncel müfredatları eğitim programları dahilinde sunulan dijital bilişim dersleri çerçevesinde değerlendirilmiş olup; bu konuda ciddi eksiklikler olduğu saptanmıştır. Bu doğrultuda mevcut müfredatların yeniden gözden geçirilmesi ve dijital çağın gereksinimlerine uygun olarak düzenlenmesi önerilmektedir.
Türkiye’de Katılım Sigortacılığı: Geleneksel Sigortacılıkla Karşılaştırmalı Bir Analiz
Authors: ERSOY Behlül , MERAL Hasan
Published: February 2024

Türkiye’de katılım sigortacılığı geleneksel sigortacılığa göre çok daha kısa bir geçmişe sahip olsa da son yıllarda gösterdiği büyüme performansı ile sigorta pazarındaki payını artırmıştır. Literatürde katılım sigortacılığına ilişkin çalışmalar, katılım ve geleneksel sigortacılık sistemlerinin işleyişleri arasında önemli farklılıklar olduğunu savunmaktadır. Öte yandan bu farklılıklar büyük oranda teorik düzeyde kalmakta, sigortacılık uygulamasında belirgin bir ayrışma yaratmamaktadır. Bu durum katılım sigortacılığının özgün bir değer önermesi geliştirmesini güçleştirmektedir. Bu noktada çalışmanın amacı, Türkiye’deki katılım ve geleneksel sigorta şirketlerinin pazarlama stratejilerini karşılaştırmalı olarak analiz ederek, katılım sigorta sektörünün gelişimini destekleyecek politika önerileri geliştirmektir. Bu amaçla, en yüksek pazar payına sahip dört katılım ve dört geleneksel sigorta şirketi iletişim, ürün ve dağıtım kanalı ana başlıklarında analiz edilmiştir. İletişim başlığında şirketlerin internet siteleri ve tanıtım filmleri, ürün başlığında ise kasko, konut ve hayat poliçeleri içerik analizi yöntemi ile incelenmiştir. Dağıtım kanalı başlığında ise şirketlerin üretim verileri kullanılarak karşılaştırmalı bir analiz yapılmıştır. Sonuçlar, Türkiye’de katılım ve geleneksel sigorta şirketlerinin iletişim ve ürün stratejilerinin büyük oranda benzer olduğunu göstermektedir. Bununla birlikte, katılım sigorta şirketlerinin ürün ve dağıtım kanalı karmaları geleneksel sigorta şirketlerinden ayrışmaktadır.
