A New Perspective on the Protection of Whistleblowers Under Echr: Halet V Luxembourg
Authors: Kafteranis Dimitrios , Andreadakis Stelios
Published: January 2024

The Luxleaks scandal, which had garnered widespread attention in 2014 and implicated A. Deltour and R. Halet, has taken a significant turn with the recent publication of the Grand Chamber’s decision in favour of Mr Halet. Initially, Deltour was officially recognised as a whistleblower by the European Court of Human Rights (ECtHR) in defence of the actions he took, while Halet faced condemnation for lacking whistleblower status. Halet had previously brought his case before the ECtHR, alleging a violation of his right to freedom of expression. However, the ECtHR’s judgment in February 2023 ultimately upheld the right to freedom of expression, marking a pivotal moment in this legal saga.

The judgment itself focused on two critical criteria for safeguarding whistle-blowers within the framework of freedom of expression: assessing the damage caused to the employer and determining whether such damage could be outweighed by the public interest, as well as evaluating the severity of the imposed sanctions.

This contribution aims to provide a critical assessment of the Luxleaks case up until the the ECtHR’s Grand Chamber decision. As this analysis will argue, the judgment holds immense significance as it introduces a fresh perspective on the notions of damage and public interest in the context of the Court’s established jurisprudence concerning whistleblower protection.

Published: January 2024

Water erosion is a major problem in the semi-arid environments of Algeria. In this vein, the objective of this study is to use the Revised Universal Soil Loss Equation (RUSLE) on the watershed of Medjerda which is located at the extreme of the North-Eastern part of the Algerian territory. Based on the crossing of various factors in raster mode under ArcGIS allows the production of diverse thematic maps corresponding to multiple factors: erosivity of precipitations, erodibility of soils, topography, the vegetal cover and the anti-erosive practices. Moreover, the risks’ map of water soil erosion was obtained depending on the combination of the previous thematic maps with four class risks has been made up indicating an average erosion value of 2.68 t/ha/year. However, this value is relatively reasonable in relation to the given rate by the interpretation of the bathymetric measures carried out in the Ain Dalia dam.
AI and politics: ensuring or threatening democracy?
Authors: KOUROUPIS Konstantinos
Published: January 2024

Artificial Intelligence constitutes one of the most fundamental pillars for the implantation of the EU Digital Agenda. Its impact both in private and public life is omnipresent. AI has become an inherent part of the political life since politicians use it for several reasons, such as to promote their strategy as well as to achieve better and closer communication with people. All this is based on the existing set of legal rules. However, there are significant issues, both ethical and legal, which pose a wide range of concerns: from the protection of fundamental rights and freedoms to the safeguard of the principle of rule of law. The core question is the following: does AI strengthen democracy or lead to its deterioration? This paper aims at demonstrating the implementation of AI in politics. Firstly, there will be pursued, via a juridical methodology, a description of the regulatory framework governing AI, in connection with justice and democracy. Following a critical approach, there will be an analysis of principal ethical and legal concerns regarding the necessity and/or efficiency of use of AI in political life. Finally, the ultimate goal of the paper is to stimulate critical thinking and suggest fruitful proposals for the safeguard of the democracy and the establishment of a trustful and powerful digital environment.

Factors Affecting a Listing's Popularity on Airbnb
Authors:   JEJU NATIONAL UNICERSITY TOURISM,BUSINESS,AND ECONOMIC RESEARCH INSTITUTE, Kang Minhyung
Published: January 2024

This study aims to understand the factors that influence the popularity of listings on Airbnb. For this purpose, data on the attributes of hosts (who are service providers), the attributes of listings (which are the core facilities of the Airbnb service), and the content of reviews (which represent the existing customers' perceptions of their experience) were obtained from Inside Airbnb, a non-for-profit data site related to Airbnb. To develop the research hypotheses, the effects of the five sub-dimensions of the SERVQUAL model, perceived value, and review sentiment on the popularity of a listing were examined. The popularity of a listing was measured by the number of new reviews, and since it is a count variable and has a skewed distribution, it was analyzed through Poisson regression. The results showed that all five dimensions of the service quality model have a positive impact on the popularity of Airbnb listings, and perceived value, which is important in the Airbnb context, also has a significant positive impact. However, the positive and negative sentiments in reviews did not yield the expected results. Our findings have academic contributions in the form of a new theoretical framework, a new dependent variable, and the application of a longitudinal research method. Additionally, they also have practical implications for the management of Airbnb listings.

Published: January 2024

Conjoint analysis is a method that predicts the consumer choice by estimating the utility of product's attributes. This study aims to investigate how citrus products can be optimized based on consumer preferences through a choice-based conjoint analysis method. Citrus is one of Jeju's main fruit and play an important part in the Jeju agricultural market. This study seeks to identify the atrribute of citrus that influence consumer choice. In this study, we conduct a choice-based conjoint analysis on four attributes of citrus, including weight, size, price, and packaging. The analysis model is the part-worth function model and the vector model. The part-worth function model estimated the utility of attribute level and the relative importance of the attributes. The vector model estimated the willingness-to-pay price, and then estimated latent class analysis. As a result, weight, size, and price had a great influence on consumer choice among the four attributes, while packaging had a relatively small influence. This study provides valuable insight to explores the optimal combination of citrus attributes preferred by consumers. The optimal combination increase the competitiveness of citrus in the market. And it provide guide to build effective product development strategies and market segmentation strategies for Jeju farmers and agricultural entrepreneurs.
Is the Reliability of Local Government Financial Accounting Information Improving?
Authors:   JEJU NATIONAL UNICERSITY TOURISM,BUSINESS,AND ECONOMIC RESEARCH INSTITUTE, Ko Mi-Hyun , Ji Chang-Eon
Published: January 2024

It has been 16 years since financial accounting for local governments using accrual based double-entry bookkeeping was introduced. The purpose of this study is to verify whether the reliability of financial statement information of local governments is improving by using Benford's Law. The reliability of the numbers was estimated by comparing the distribution of the first digit of the assets and liabilities with the Benford distribution. As a result of the analysis, it is confirmed that the assets and liabilities for the past 16 years did not follow the Benford distribution as the MAD test result value and the KS statistic exceeded the critical value. Assets and assets in each statement of financial position for the first 8 years of the introduction of the accrual-based double-entry bookkeeping system and for the first 8 years after financial statements began to be included as mandatory documents in the settlement of accounts of local governments. Liabilities figures still does not follow the Benford distribution. We suggest that there is a need to move from a simple review system to an audit system for local governments' financial statements.

Authors:   JEJU NATIONAL UNICERSITY TOURISM,BUSINESS,AND ECONOMIC RESEARCH INSTITUTE, Kim Daniel J.
Published: January 2024

Education is an important issue in economic growth studies since, presumably, educational attainment increases the level of human capital. Hence, there is a huge economic literature that analyze and explain the relationship between education and economic growth. To understand whether education contributes to economic growth, the purpose of this paper is to explain and critically review a selection of some of the most important and seminal literature on the issue. After introducing the subject of the study, the paper explains the relationship between education and economic growth, starting with the earlier, original form of growth models, and then continuing on to some of the more recent models that incorporates human capital formation. The literature is divided according to the majority and the minitory views. The paper, then, deals with the issue of education as an indirect factor of growth, through the effects on fertility, income inequality, and intergenerational productivity. The paper also considers the dissenting, or minority view on the issue.

Authors: Dahman Haifa , Aljabry Ali
Published: January 2024

Pediatric hemophagocytic lymphohistiocytosis (HLH) is a potentially life-threatening condition with significant diagnostic and therapeutic difficulties. The purpose of this study was to describe the clinical presentation, the diagnostic challenges, and the outcomes of HLH in children assessed at Mukalla hospital.
Data from 20 medical records of HLH patients admitted between January 2010 and May 2022 were retrospectively analyzed.
The median age at presentation was 3.5 ± 5.1 years. M: F ratio was 1:1. The median time for referral to the hospital was 30±64 days. The most common clinical manifestations were fever and pallor in 95% of cases, and splenomegaly (85%). Hepatomegaly, chest, renal, and neurological manifestations were detected in 80%, 45%, 15%, and 20% of cases, respectively. Bone marrow (BM) hemophagocytosis was detected in 60 % of cases. Sixteen patients fulfilled the HLH diagnostic criteria, and eleven patients (55%) received the HLH 2004 protocol. Out of the 20 patients, three (15%) patients are alive. Fourteen patients died, with overall mortality of 82.35%. All mortalities were due to HLH disease with multi-organ failure. Relapse was noticed in five patients either during treatment or after full recovery.
Pediatric HLH is a challenging emergency with a high mortality rate. High clinical suspicion is essential for early detection to facilitate early intervention to improve the prognosis.

Typy zaburzeń językowych w zespole Aspergera
Authors: Korendo Marta
Published: January 2024

For many years, both the DSM‑IV and ICD-10 have built up the misconception that there are no language disorders in Asperger’s syndrome. This has had a significant impact on the problems with the diagnosis of Asperger syndrome, and has been the cause of many misdiagnoses. The current editions: DSM-5 and ICD-11 have not changed the established approach. Many years of research and clinical experience have allowed the author of this article to verify the view of normal speech and communication development in Asperger syndrome. We now know that children with ZA may manifest different types of disorders, concerning both systemic and communicative competence. The author of the article characterises the types of language problems observed in ZA, including: the specificity of early speech development, alalia (delayed speech development), aphasia, comprehension of speech and intonation of speech and indicates their sources and examples. This is of great importance in the context of the correct diagnosis and therapy of children on the autism spectrum, including the differential diagnosis of autism and Asperger syndrome.
Sytuacja socjolingwistyczna mniejszości bułgarskiej na południowo‑wschodniej Ukrainie
Authors: Krasowska Helena
Published: January 2024

The subject of the research is the Bulgarian minority living in the south‑eastern areas of Ukraine. The aim of the article is to present the sociolinguistic situation of this minority. Particular attention was paid to the use of the Bulgarian language in the family and neighborhood sphere. The determinants that maintain or lead to the disappearance of the Bulgarian culture and language in the Zaporozhye region are indicated. Field research among the Bulgarian minority was conducted in 2013–2022 on the margin of research that was conducted among the Polish minority in this region. The leaders emphasized that no one at home uses the Bulgarian language, although some people remember how their grandparents once used the dialectal variety of the Bulgarian language. In the neighborhood environment, no one speaks Bulgarian in this area either. No one speaks Bulgarian in the families, and Bulgarian is not spoken in the neighborhood either. Living in a linguistically different environment was conducive to rapid assimilation to most of the Russian language. In the family sphere and intergenerational transmission, only Russian is present. The research results also make it possible to indicate the reasons for the loss of linguistic continuity among the Bulgarian minority in the Zaporizhia region. Currently, representatives of the Bulgarian minority are learning Ukrainian.
Z polskich drobiazgów słownikowych Tadeusza Szymańskiego: japa
Authors: Fałowski Adam
Published: January 2024

The article deals with the Polish dialectal word japa, which was the subject of interest of T. Szymanski. It presents a point in the discussion concerning the etymology of the mentioned dialectal word. The author has come to the following conclusions: 1) it is necessary to consider separately etymologically the Proto‑Slavic *ěpa ‘a growth on a tree, a swollen place on the body’ and the Polish and Belorussian dialectal word japa which means ‘mouth; a large hole’, 2) it is unlikely to be a word derived from a child language, 3) the Serbian and Croatian items should be considered as etymologically identical to the Polish and East Slavic ones, 4) japa ‘mouth, map, etc.’ is close to ziapa with the same meaning, 5) the form with onset ja- (japa) is a result of changing word structure, 6) regional spreading of the Polish dialectal words japa and ziapa could indicate on their Ruthenian roots, 7) it is difficult to establish conclusively whether German word forms japen, jappen which mean ‘to open one’s mouth; to catch, grasp with one’s mouth’ have played any part in this process.

exotización hollywoodense de Colombia mediante la relación civilización-barbarie y el tratamiento de su espacio como jardín-desierto
Authors: Méndez Mihura María Ximena
Published: January 2024

Este trabajo se propone visibilizar cómo ha sido representada Colombia en una película de Hollywood, industria que en muchos films se ha preocupado por mostrar este país y a sus habitantes. Por medio del análisis de Romancing The Stone(1984), de Robert Zemeckis, mostraremos una particular visión de Colombia, exotizada mediante diferentes recursos. En algunos momentos mediante la confusión o el vínculo estrecho con México y lo mexicano; en otros, por el enlace con lo peligroso o con lo exótico. Siguiendo a Tudor (1989), se observará que la relación civilización-barbarie plantea en realidad otros dos grandes ejes simbólicos que utilizan los realizadores de películas para tratar el espacio: el jardín y el desierto.

Debut sexual, uso de métodos anticonceptivos y aspiraciones educativas en un grupo de madres adolescentes en Ciudad Juárez, Chihuahua
Authors: Martínez Canizales Georgina
Published: January 2024

En este trabajo se analizan diversas conductas sobre sexualidad y las expectativas educativas de un grupo de madres adolescentes en Ciudad Juárez, Chihuahua. El objetivo es conocer el contexto en el que ocurre el embarazo adolescente y cómo afecta las expectativas que sobre su formación educativa tienen las adolescentes, así como aquellos factores que limitan o facilitan la continuación de sus estudios cuando ellas así se lo han planteado.

Se entrevistó a 67 jóvenes con embarazo adolescente provenientes de diversos puntos de Ciudad Juárez, con el común denominador de provenir de poblaciones de escasos recursos. Este estudio tiene una aproximación cualitativa. La recolección de información se llevó a cabo mediante 7 grupos focales y un cuestionario que proporcionó información sociodemográfica básica sobre las jóvenes y sus familias.

Los resultados muestran que gran parte de las jóvenes debutan sexualmente en el contexto de una relación de pareja, la mitad utilizó algún anticonceptivo en su debut sexual; sin embargo, conforme se afianzó la relación dejaron de verlo como necesario. Poco más de la mitad dijo no haber planeado su embarazo. Más de la mitad de las jóvenes ya había dejado la escuela antes del embarazo, una buena parte de éstas no se planteaba continuar sus estudios. Las jóvenes que siguieron estudiando vieron favorecida su permanencia por el apoyo familiar para el cuidado de los hijos: quienes no tuvieron apoyo familiar, o cuya necesidad económica era mayor, tuvieron que posponer sus planes educativos.

Decir perpetrador: historias de vida de victimarios
Authors: Alfaro Andonie Hugo Fauzi , González Orozco Paulina
Published: January 2024

Este trabajo propone una clasificación de los tipos de victimarios o perpetradores y la importancia de trabajar con sus historias de vida para la investigación social. A través de una revisión bibliográfica se propone una clasificación de cuatro tipos generales de perpetradores: los de la contrainsurgencia y la represión (que se centra en los personajes clave de las dictaduras en América Latina); los victimarios fuera del poder político (comunmente relacionados con las clases populares); los de “cuello blanco” (ilícitos cometidos por individuos o entidades privilegiadas en poder político y económico) y los victimarios estructurales (que reproducen conductas como el machismo, el racismo y/o la xenofobia). Además, se construye un apartado sobre cuestiones éticas y metodológicas al trabajar con historias de vida de quienes han violentado derechos y garantías para evitar caer en apologías del delito.

Published: January 2024

En el presente artículo se analizan las diversas construcciones conceptuales originadas desde la postura del derecho positivo internacional y autores contemporáneos que desarrollan la configuración de pensamiento y de interacción social denominado extranjería. En concomitancia, se establece una serie de argumentos que permiten analizar la extranjería a través de sistemas políticos, económicos y sociales primigenios, utilizando categorías de análisis que permiten identificar puntualmente -desde la normatividad- las denominaciones utilizadas por los estados-nación. Por último, se expone una de las figuras normativas del Estado mexicano en el que se construye la invisibilidad de personas, pero no de su poder adquisitivo o de inversión. La metodología implementada conlleva un enfoque cualitativo, particularmente descriptivo, con apoyo bibliográfico y normativo, cuyas variables son extranjería, emigrante, migrante, inmigrante y norma positiva.

Authors: HAMURCİ Yağmur , IHLAMUR Murat , ABAMOR Emrah Şefik
Published: January 2024

Kanser, hücrelerin kontrolsüz olarak çoğalması sonucu oluşan ve kardiyovasküler hastalıklardan sonra dünyada ölüm oranı en yüksek hastalıktır. Mide kanseri, dünyada en yaygın görülen kanser türlerinden biri olmakla birlikte GLOBOCAN 2020 yaklaşık 800000 ölüme neden olmuş ve yaklaşık 1,1 milyon yeni mide kanseri vakası tespit edilmiştir. Tedavisinde cerrahi, kemoterapi, ilaç tedavisi gibi yöntemler sıklıkla kullanılsa da etkili sonuçlar vermemektedir. Bu nedenle mide kanseri oluşmadan önce bağışıklık oluşturularak hastalığın başlamasını engellenmeli veya elde edilen bağışıklık sayesinde daha hızlı bir şekilde tedavilerden yanıt alınmasını sağlanmalıdır. Aşılamanın kansere karşı bağışıklık sistemini harekette geçirdiğine dair literatürde yer alan çalışmalar, kanser aşılarında umut verici sonuçlar ortaya koymaktadır. Bu çalışmada, mide kanserine yönelik geliştirilen aşı formülasyonlarının immünostimülan etkileri, J774 murin makrofaj, THP-1 insan makrofaj ve L929 fibroblast hücrelerinde araştırılmış ve sitotoksisiteleri belirlenmiştir. AGS mide kanseri hücre hattından dondurma-çözdürme yöntemi ile elde edilen antijenler Freund’s ve Incomlete Freund’s adjuvanları ile kombine edilmiştir. Çalışma sonuçlarına göre, geliştirilen aşı formülasyonlarının toksik etkilerinin düşük olduğu ve en yüksek immünostimülan etkinliğin 40 µg/ml konsantrasyonda olduğu tespit edilmiştir. Kullanılan üç hücre hattında maksimum protein konsantrasyonunda hücre canlılıkları %75‘den yüksek olduğu belirlenmiştir. Elde edilen sonuçların mide kanserine yönelik aşı formülasyonlarının geliştirmesine yardımcı olacağı ve kanser immünoterapisi çalışan araştırmacılar için bu verilerin değerlendirilebileceği söylenebilir.

Authors: TÖZER Kemal Dirgen , GÜRCANLI Gürkan Emre , ÇELİK Tahir , AKBOĞA KALE Özge
Published: January 2024

Prevention through Design (PtD) and Design for Safety (DfS) are now being considered in relation to occupational health and safety and building design. A recent collection of studies suggests that certain decisions made by designers during the design process are at the root of many risks. A study was undertaken to relate falls from height to the conventional design process for reinforced concrete buildings. This was achieved by dividing the building design process into stages. During the design phase, input was gathered from architects and engineers working in the sector. Accident types were identified based on studies of occupational accident investigation reports from the Ministry of Labor. Of the 15 types of fall from height accidents studied, 12 were attributed to design decisions. Of these, 6 different accident types were associated with 5 or more design decisions, while 2 of these were associated with 3 or 4 design decisions. The remaining 4 types were linked to only 1 design decision.

Bases of fixed point subalgebras on nilpotent Leibniz algebras
Authors: YAPTI ÖZKURT Zeynep
Published: January 2024

Let K be a field of characteristic zero, X={x_(1,) x_2,…,x_n} and R_m={r_(1,) ,…,r_m} be two sets of variables, F be the free left nitpotent Leibniz algebra generated by X, and K[R_m ] be the commutative polynomial algebra generated by R_m over the base field K. The fixed point subalgebra of an automorphism φ is the subalgebra of F consisting of elements that are invariant under the automorphism. In this work, we consider specific automorphisms of F and determine the fixed point subalgebras of these automorphisms. Then, we find bases of these fixed point subalgebras.

Variable exponent Lebesgue spaces are generalizations of classical Lebesgue spaces and have importance in many branches of Mathematical Analysis. Especially, direct and converse theorems and their improvements are studied by many mathematicians in these spaces. In this article, direct and converse predictions for the rate of convergence of Fejér means of functions belonging to the variable Lebesgue space L^p(⋅) (R) are established by using an appropriate K-functional. In this way, the result of Z. Ditzian on Fejér means in classical Lebesgue spaces L^p (R)(1

While previous research has examined the impact of cross-border migrants on economic development and other social issues, limited studies have focused on the potential effects of migrants on the mental health of the native population. This paper investigates the impact of cross-border migrants on the mental health of natives in Thailand, considering various mental health disorders. This study analyzes 77 provincial data sets from 2016 to 2021 using a spatial panel autoregressive model. The findings suggest that the presence of migrants did not have an adverse influence on the mental health of the native population at a 5% significance level. Notably, there is a reduction in the prevalence of substance abuse disorders associated with the presence of migrants at the 5% significance level. Additionally, unemployment, education, public health services, technological infrastructure, health risk behavior, and age are significant contributors to the mental health of natives at a 5% significance level. The study underscores the need for a comprehensive approach to developing effective mental health policies and initiatives that address these multiple contributors.
A cidadania brasileira entre democracia e neoliberalismo:
Authors: Verbicaro Loiane Prado , Silva Paulo Henrique Araújo da
Published: January 2024

O presente artigo investiga de que maneira os compromissos por igualdade social determinados pela Constituição de 1988 são comprometidos pelos ditames neoliberais de expansão e liberdade do mercado, que se manifesta tanto na forma de um projeto de Estado austero quanto de uma cidadania mercadológica. Foi empregado o método dialético, uma abordagem transdisciplinar que permite a superação de uma visão liberal, dogmática e acrítica do mundo e a percepção de contradições entre a relação jurídica e a formação econômica, política e histórica de uma sociedade. A revisão sistemática da bibliografia foi a técnica selecionada, esta que possui uma natureza qualitativa e exploratória como forma de fornecer uma compreensão contra-hegemônica que permite uma visão dos direitos como fenômenos sociopolíticos em disputa.  A partir de uma análise crítica da bibliografia selecionada, o acesso à justiça revela-se como um conceito-chave à questão social de luta constante por direitos, na forma da cidadania, e de participação político-jurídica efetiva de grupos atravessados pelos estratos de raça, classe e gênero, questão afetada não só pelos efeitos do neoliberalismo sobre a ideia de justiça social, mas também das desigualdades mantidas e reproduzidas pela continuidade de uma herança patrimonialista, escravocrata e sexista que limita a cidadania.
Impactos da pandemia covid-19 sobre o mundo (capitalista) do trabalho:
Authors: Dias Antonio
Published: January 2024

Desde 2019 o mundo está sob os impactos da pandemia do COVID-19. Apesar de esse vírus ter causado mortes de milhões de pessoas, a lógica do Capital enxerga esse fato, sobretudo, como gênese da atual crise da economia mundial. Sobre isso, neste artigo, com apoio das ideias de Karl Marx, abordaremos os possíveis efeitos do Coronavírus sobre a lógica e os poderes do vigente e hegemônico modo de produção no mundo: o capitalista. A lógica do Capital, na perspectiva marxiana, é um conjunto de princípios, ideias, valores e práticas que fundamentam o Capital como poder onímodo gestor do pensar, do ser e fazer dos homens que vivem em sociedade. Esta condição do Capital implica opressão política, alienação intelectual e moral, e especialmente exploração econômica no mundo capitalista do trabalho. Elegemos este último aspecto como objetivo deste escrito. Iremos destacar, sob um viés filosófico marxista, o que entendemos ser os prováveis efeitos da crise causada pela Covid-19 sobre o trabalho regido pela lógica e poderes do Capital. É fato que essa lógica e tais poderes sofreram abalos causados pela crise do Coronavírus. Contudo, esses abalos geraram algumas fissuras? E estas, caos existam, têm potencial para desestabilizar a lógica e os poderes do Capital, ou este conseguirá metamorfosear-se para escapar incólume da crise e ainda se potencializar como poder ordenador da socialidade?

Published: January 2024

O presente trabalho pretende enfrentar uma contradição posta diante do profissional que atua na gerontologia e ao qual se põe a reflexão, ainda que acerca dela só se possa refletir teórica e filosoficamente, trata-se do exame das implicações contidas nos debates sobre interrupção da vida. Como problema de pesquisa é moralmente justificável interromper a vida do paciente dado a natureza incurável do mal que lhe acomete? Do ponto de vista das referências teóricas note-se que esse debate percorre não apenas a teoria e filosofia do direito e do ponto de vista das consequências práticas alguns desses procedimentos foram superadas mediante autorização do paciente em consentimento livre e informado e diante de moléstias absolutamente incuráveis.

Objetivo: Descrever o processo de adaptação transcultural e validação de conteúdo da Postpartum Specific Anxiety Scale para o português brasileiro. Métodos: Trata-se de um estudo metodológico desenvolvido em cinco etapas: tradução, síntese, retrotradução, avaliação por especialistas e pré-teste. O comitê de especialistas, composto por 6 doutores, avaliou a equivalência semântica, idiomática, experiencial, cultural e a relevância de cada item através do Índice de Validade de Conteúdo. O pré-teste foi realizado com 30 mulheres nos primeiros 6 meses após o parto. Resultados: Após avaliação dos especialistas, seis itens não alcançaram a concordância de 80% em alguma das equivalências. Entretanto, todos os itens obtiveram concordância superior a 80% em relação à relevância. As participantes do pré-teste sugeriram alteração em um item para facilitar a compreensão. Conclusão: A Postpartum Specific Anxiety Scale foi adaptada para o português brasileiro. Contudo, é necessária a realização de estudos que avaliem suas propriedades psicométricas para que seja realizada a validação da mesma.

The extensive use of pesticides may cause acute and chronic intoxication. Therefore, this study aimed to reveal the associations between pesticide exposure and serum markers for stroke risk factors in farmers. A cross-sectional study was conducted with farmers, who used chemical pesticides in Seloprojo Village, Ngablak District, Magelang Regency, Central Java Province, Indonesia. A questionnaire containing demographics, pesticide use, and aspects related to work was employed. Measurements of serum cholesterol, uric acid, glucose, cholinesterase, and fibrinogen levels were also conducted. Of the 106 subjects, 31 (29.2%) used organophosphates as chemical pesticides. There was a significant difference between organophosphate and nonorganophosphate groups in plasma fibrinogen levels. The organophosphate group had higher levels of fibrinogen (292.29 ± 67.56 mg/dL) than the non-organophosphate group (255.24 ± 38.90 mg/dL). Of the studied risk factors for stroke, there is a significant association between organophosphate exposure and increased plasma fibrinogen levels.

Published: January 2024

This study was a survey to explore ways to establish non-face-to-face care services for vulnerable older adults. The authors investigated factors that influence the intention of the older adults who are recipients of care services to continue using AI speakers. A questionnaire survey consisting of 26 questions related to the use of AI speakers was conducted in the summer of 2022 targeting 179 elderly people using AI speakers, and the data were analyzed using regression analyses and others. The results showed that the older adults with lower educational levels, poorer health, and lower economic status tended to have a higher intention to continue using AI speakers. Moreover, it was found that the more frequently the older adults used AI speakers and the more confidence they showed in the speakers’ functions, the higher their intention to continue using them. The findings of this study suggest the need for updating AI speaker functions as a means of revitalizing non-face-to-face caregiving services for vulnerable older adults. In addition, it was suggested that educational programs should be provided to use AI speakers more easily for the vulnerable ones than now. This study has a great significance in that it sought ways to continuously utilize AI speakers in the care area of the community-dwelling vulnerable older adults.
