Authors: Sharma Nikita , Wrede Christian , Bastoni Sofia , Braakman-Jansen Annemarie , van Gemert-Pijnen Lisette
Published: October 2024

Background

With the growing need of support for informal caregivers (ICs) and care recipients (CRs) during COVID-19, the uptake of digital care collaboration platforms such as Caren increased. Caren is a platform designed to (1) improve communication and coordination between ICs and health care professionals, (2) provide a better overview of the care process, and (3) enhance safe information sharing within the care network. Insights on the impact of COVID-19 on the implementation and use of informal care platforms such as Caren are still lacking.

Objective

This study aimed to (1) identify technology developers’ lessons learned from the continued implementation of Caren during COVID-19 and (2) examine pre-post COVID-19 changes in usage behavior and support functionality use of Caren.

Methods

A focus group with developers of the Caren platform (N=3) was conducted to extract implementation lessons learned. Focus group data were first analyzed deductively, using the Consolidated Framework for Implementation Research domains (ie, individual characteristics, intervention characteristics, inner setting, and outer setting). Later, inductive analysis of overarching themes was performed. Furthermore, survey data were collected in 2019 (N=11,635) and 2022 (N=5573) among Caren platform users for comparing usage behavior and support functionality use. Data were analyzed using descriptive and inferential statistics.

Results

Several lessons from the continued implementation of Caren during COVID-19 were identified. Those included, for example, alternative ways to engage with end users, incorporating automated user support and large-scale communication features, considering the fluctuation of user groups, and addressing data transparency concerns in health care. Quantitative results showed that the number of ICs and CRs who used Caren several times per day increased significantly (P<.001 for ICs and CRs) between 2019 (ICs: 23.8%; CRs: 23.2%) and 2022 (ICs: 35.2%; CRs: 37%), as well as the use of certain support functionalities such as a digital agenda to make and view appointments, a messaging function to receive updates and communicate with formal and informal caregivers, and digital notes to store important information.

Conclusions

Our study offers insights into the influence of the COVID-19 pandemic on the usage and implementation of the digital informal care support platform Caren. The study shows how platform developers maintained the implementation during COVID-19 and which support functionalities gained relevance among ICs and CRs throughout the pandemic. The findings can be used to improve the design and implementation of current and future digital platforms to support informal care toward the “new digital normal.”

Authors: Zhu Yan-Yan , Ye Ze-Hao , Chu Zhen-Xing , Liu Yingjie , Wei Jie , Jia Le , Jiang Yong-Jun , Shang Hong , Hu Qing-Hai
Published: October 2024

Background

To date, no randomized controlled trials have specifically addressed behavior changes after HIV self-testing (HIVST) among transgender women.

Objective

This study aims to evaluate the effects of HIVST on changes in HIV testing behavior, frequency of condomless sex, and partner numbers among transgender women in China.

Methods

Participants were recruited from 2 Chinese cities using both online and offline methods. Transgender women were randomly assigned to receive an HIVST intervention. Data from the previous 3 months were collected at baseline, 3 months, and 6 months. The primary outcome was the mean change in the number of HIV tests among transgender women during the 6-month follow-up. An intention-to-treat analysis was conducted. The statistical analysis used analysis of covariance and linear mixed-effects models.

Results

From February to June 2021, and 255 transgender women were recruited, of which only 36.5% (93/255) had a steady job, and 27.1% (69/255) earned less than US $414.9 of income per month. They were randomly assigned to the intervention (n=127) and control (n=128) groups. At 6 months, the mean number of HIV tests was 2.14 (95% CI 1.80-2.48) in the intervention group and 1.19 (95% CI 0.99-1.40) in the control group (P<.001), with increases of 0.84 (95% CI 0.54-1.14) and 0.11 (95% CI –0.19-0.41) over 6 months, respectively. The net increase was 0.73 (95% CI 0.31-1.15; P<.001), with a similar adjusted result. No significant differences in the frequency of condomless sex or partner numbers were observed between the 2 groups.

Conclusions

HIVST is an effective strategy for enhancing regular HIV testing behavior among transgender women in China. This strategy should be combined with measures to address the financial vulnerability of the transgender women community to reduce subsequent risk behaviors, including condomless sex.

A Personalized, Transdiagnostic Smartphone App (Mello) Targeting Repetitive Negative Thinking for Depression and Anxiety: Qualitative Analysis of Young People’s Experience
Authors: Valentine Lee , Arnold Chelsea , Nicholas Jennifer , Castagnini Emily , Malouf Jessi , Alvarez-Jimenez Mario , Bell Imogen H
Published: October 2024

Background

The increasing rates of mental health challenges among young people highlight an urgent need for accessible and effective treatment. However, current mental health systems face unprecedented demand, leaving most young people globally with unmet mental health needs. Smartphones present a promising solution to this issue by offering in-the-moment support through innovative just-in-time adaptive interventions, which provide support based on real-time data.

Objective

This study explores young people’s experiences with Mello, a just-in-time adaptive intervention that focuses on the transdiagnostic mechanism of repetitive negative thinking (RNT), a significant factor contributing to youth depression and anxiety.

Methods

Semistructured qualitative interviews were conducted with 15 participants aged 16 to 25 years, all of whom had previously participated in a pilot randomized controlled trial of Mello. Of the 15 participants, 9 (60%) identified as women, 4 (27%) as men (including 1 transgender man), and 2 (13%) as nonbinary. Interviews focused on participants’ experiences with the Mello app, factors influencing engagement, perceived benefits and limitations, and suggestions for future improvements. Thematic analysis was used to analyze the data.

Results

The analysis identified three superordinate themes: Mello as a tool for intentional reflection; doing therapy your own way; and barriers to engagement during low mood, anxiety, and RNT. Theme 1 explored young people’s experiences of how the app facilitated active management of negative thoughts and supported the development of reflective habits, contrasting with their typical strategies of avoidance or resistance. Theme 2 highlighted the value of the app’s self-guided nature, with a particular focus on its flexibility and accessibility, particularly when compared to traditional face-to-face therapy. Finally, theme 3 addressed barriers to engagement, particularly during emotionally difficult times, with participants reporting feeling “stuck” in their negative thoughts. To mitigate these challenges, participants suggested incorporating gamification elements, such as progress-tracking visuals, to enhance motivation and increase engagement with the app.

Conclusions

Our findings underscored the value of Mello in promoting intentional engagement and reflection with RNT, consistent with prior research that emphasizes the effectiveness of tailored interventions. Although some users valued the self-guided nature of the application, others encountered difficulties with motivation. Future research should explore strategies to enhance engagement for young people with low mood and motivation, such as co-design methodologies, advanced personalization features, and gamification techniques.

Published: October 2024

BACKGROUND

Sexual harassment (SH) and sexual assault (SA) are serious public health problems among US service members. Few SH and SA prevention interventions have been developed exclusively for the military. Code of Respect (X-CoRe) is an innovative web-based, multilevel, SA and SH intervention designed exclusively for the active-duty Air Force. The program’s goal is to increase Airmen’s knowledge and skills to build and maintain respectful relationships, ultimately reducing SH and SA and enhancing Airmen’s overall well-being and mission readiness.

OBJECTIVE

This pilot study aimed to assess the short-term psychosocial impact (eg, knowledge, attitudes, and self-efficacy) of the web-based component of X-CoRe on a sample of junior enlisted and midlevel Airmen.

METHODS

Airmen from a military installation located in the Northeastern United States were recruited to complete the 10 web-based modules in X-CoRe (9/15, 60% male; 7/15, 54% aged 30-35 years). Participants were given pretests and posttests to measure short-term psychosocial outcomes associated with SH and SA. Descriptive statistics and paired 2-tailed t tests were conducted to assess differences from preintervention to postintervention time points.

RESULTS

After completing X-CoRe, participants had a significantly greater understanding of active consent (P=.04), confidence in their healthy relationship skills (P=.045), and confidence to intervene as bystanders (P=.01). Although not statistically significant (P>.05), mean scores in attitudes about SH, couple violence, and cyberbullying; perceptions of sexual misconduct as part of military life; and relationship skills self-efficacy with a romantic partner and friend also improved.

CONCLUSIONS

The findings from this study demonstrate X-CoRe’s effectiveness in improving critical determinants of SH and SA, making it a promising intervention for SH and SA prevention. More rigorous research is needed to determine X-CoRe’s impact on SH and SA victimization and the long-term impact on associated psychosocial determinants.
Validating a Patient-Reported Outcome Measure to Improve Emergency Department Asthma Care: An Observational Study Protocol (Preprint)
Authors: Lin Michelle , Gordon Lauren , Richardson Lynne D
Published: October 2024

BACKGROUND

Asthma affects 1 in every 12 persons in the U.S., resulting in 1.9 million emergency department (ED) visits annually. However, the lack of patient-reported outcomes measures (PROMs) validated for use in the ED limits the evaluation of interventions to improve ED asthma care.

OBJECTIVE

To address this knowledge gap, this study protocol will (1) develop and test the validity and reliability of the Patient Reported Outcomes for Acute Asthma Care and Treatment instrument; 2) test whether receiving more guideline-concordant emergency Department (ED) care is associated with improved PROAACT responses; and 3) evaluate the association between PROAACT score and subsequent ED revisits and hospitalizations.

METHODS

This is a prospective cohort study of adult patients visiting the ED for acute asthma exacerbation across 3 EDs at an urban, tertiary care health system. Eligible patients are age 18 or older, have a prior diagnosis of asthma (self-reported or documented in the electronic health record), English-speaking, and experiencing an ED visit for asthma exacerbation as determined by treating clinician. Enrolled participants complete an initial PROM survey during their ED visit assessing their symptoms in the preceding seven days, then complete a follow-up survey 7 days after ED discharge assessing changes in the symptoms in the subsequent seven days. To test whether guideline-concordant care is associated with improved PROAACT scores, we will conduct retrospective chart review of medications ordered during the ED visit, then compare guideline adherence to changes in PROAACT scores. To test whether improved PROAACT scores are associated with fewer return ED visits and hospitalizations, we will extract all-cause ED visits and hospitalizations within 30 days from a regional health information exchange, then compared utilization to changes in PROAACT scores. We will use item response theory to develop scale responses based on summed item responses, which will allow us to test associations with clinical outcomes, including adherence to guideline-recommended care and return ED visits and hospitalizations.

RESULTS

Recruitment is ongoing and has experienced numerous challenges related to the COVID pandemic. To date, we have enrolled over 250 participants and have completed over 200 follow-ups. Recruitment is expected to conclude in spring 2025.

CONCLUSIONS

Our study is intended to validate the use of PROMs during ED visits for acute asthma exacerbation among adult patients. Completion of the proposed aims will result in one of the first PROMs intended for use among adult ED patients and support the feasibility of collecting PROMs in the ED setting.

Authors: Hou Yu , Bishop Jeffrey R , Liu Hongfang , Zhang Rui
Published: October 2024

BACKGROUND

Dietary supplements (DS) are widely used to add nutritional value to the diet, containing vitamins, minerals, herbs, amino acids, and other substances. Despite their popularity, DS are regulated less stringently compared to prescription drugs, leading to challenges related to efficacy, safety, and misinformation. There is a critical need for accurate resources to support DS-related decision-making for consumers and healthcare providers.

OBJECTIVE

To improve the accuracy and reliability of DS question answering by integrating a novel Retrieval-Augmented Generation (RAG) system with an enhanced DS knowledge base and a user-friendly interface.

METHODS

We developed iDISK2.0, a DS knowledge system, by integrating updated data from multiple trusted sources, including NMCD, MSKCC, DSLD, and NHPD, using advanced strategies to reduce data noise. iDISK2.0 was implemented with a RAG system, combining the capabilities of large language models (LLMs) and a biomedical knowledge graph (BKG) to mitigate hallucination issues found in standalone LLMs. The RAG system utilizes GPT-4 to retrieve contextually relevant subgraphs from the BKG based on entities identified in the user query. A user-friendly interface was developed to facilitate easy access to DS knowledge through conversational inputs.

RESULTS

iDISK2.0 contains 174,317 entities across seven types, six relationship types, and 471,063 attributes. The iDISK2.0-RAG system demonstrated significant improvements in DS information retrieval accuracy. Evaluation results indicated over 95% accuracy in answering True/False and multiple-choice DS-related questions, outperforming standalone LLMs. The user interface enabled efficient interaction, supporting free-form text input and providing accurate responses. Integration strategies minimized data noise, ensuring access to up-to-date DS information.

CONCLUSIONS

The integration of iDISK2.0 with a RAG system effectively addresses limitations of standalone LLMs, resulting in a reliable solution for DS information retrieval. This study highlights the importance of combining structured knowledge graphs with advanced language models to enhance the accuracy of information retrieval systems, ultimately supporting better-informed decision-making in DS research and healthcare

Perubahan Benteng Oranje di Ternate – Maluku Utara (Abad XVII-XX)
Authors: Suwindiatrini Komang Ayu , Nayati Widya
Published: October 2024

The Indonesian archipelago has been known for centuries as a source of spices that are favored in many countries. The desire to obtain these spices from the first source has brought Europeans to the islands since 15th century. They sent their maritime fleets to establish trading posts in the archipelago, especially in Maluku which was rich in nutmeg and cloves. One of the archaeological remains that serves as evidence of the presence and control of Europeans, especially the Dutch, in this area is the existence of Fort Oranje in Ternate. However, there is not much of the historical background on the development of Fort Oranje has been revealed so far. This paper attempts to fill the dearth of information about the fort. The study was conducted by identifying the attributes shown in at least five drawings and plans of the Fort, which were then combined with existing historical data. The results showed that there were several changes in the form, function and role of Fort Oranje from the beginning of its establishment to the present. The reasons for these changes are mainly due to the needs of the Dutch communities who lived in the fort as well as the changing political and security condition throughout its history. Another contributing factor is government policy both during the colonial period and after Indonesia's independence. Due to the limited amount of visual data to reconstruct the long development, only a few stages of Fort Oranje transformation can be revealed.

Selama berabad-abad, kepulauan Indonesia telah dikenal sebagai sumber rempah yang digemari di banyak negara. Keinginan untuk mendapatkan rempah-rempah ini dari sumber pertama telah membawa bangsa Eropa ke kepulauan ini sejak akhir abad ke-15. Mereka mengirimkan armada lautnya untuk mendirikan pos-pos perdagangan di Nusantara, terutama di Maluku yang kaya akan pala dan cengkeh. Salah satu peninggalan arkeologi yang menjadi bukti kehadiran dan penguasaan bangsa Eropa, khususnya Belanda, di kepulauan rempah-rempah ini adalah keberadaan Benteng Oranje di Ternate. Namun, sejauh ini belum banyak latar belakang sejarah perkembangan Benteng Oranje yang terungkap. Tulisan ini mencoba mengisi kelangkaan informasi mengenai benteng tersebut dengan menyajikan hasil kajian terhadap data visual Benteng Oranje berupa gambar dan denah lama yang masih dapat diakses. Kajian dilakukan dengan mengidentifikasi atribut-atribut yang ditunjukkan pada setidaknya lima gambar dan denah benteng, yang kemudian dipadukan dengan data sejarah historis yang ada. Hasil penelitian menunjukkan bahwa terdapat beberapa perubahan bentuk, fungsi dan peran Benteng Oranje dari awal berdirinya hingga saat ini. Penyebab perubahan tersebut terutama disebabkan oleh perubahan kebutuhan masyarakat Belanda yang tinggal di dalam benteng serta situasi politik dan keamanan yang terus berubah sepanjang sejarahnya. Faktor lain yang turut berperan adalah kebijakan pemerintah baik selama masa kolonial maupun setelah kemerdekaan Indonesia.
Pengaruh Variabel Bentanglahan terhadap Persebaran Candi Hindu di Wilayah Selatan Gunung Kelud, Blitar, Jawa Timur
Authors: Wicaksono Antonius Satrio , Yuwono J. Susetyo Edy
Published: October 2024

There are a large number of Hindu temples from the Kadiri, Singhasari and Majapahit periods in the southern region of Kelud Volcano. However, archaeological research in this region, especially in Blitar, has never addressed the overall configuration of the temples' locations and their relationship to the physical landscape. This research attempts to fill this gap by applying an archaeological landscape approach to investigate how elements of the southern Kelud landscape, such as landform, land cover, and hydrology, have affected the distribution of temple sites in the region. Data were collected through field surveys as well as literature and map studies. This research shows that in the 10th to 16th century the majority of the Hindu temples were built in the high potential area for human life with fertile lands and not far from water resources. Fewer temples were built in areas with mediocre potential, while the least potential areas were not prioritized for temple sites. The area occupied by most temples would have the prospect of supporting human living needs and also meet the general requirements for selecting temple sites.

Wilayah selatan Gunung Kelud mempunyai banyak candi Hindu dari zaman Kadiri, Singhasari, dan Majapahit. Namun demikian, selama ini penelitian arkeologi wilayah ini, terutama Blitar, masih belum membahas candi-candi secara menyeluruh sebagai himpunan, begitupun hubungannya dengan kondisi bentanglahan hampir tidak pernah dikaji. Penelitian ini menerapkan pendekatan arkeologi bentanglahan untuk meninjau bagaimana bentanglahan wilayah selatan Gunung Kelud, sebagaimana tercermin dari variabel bentuklahan, tutupan lahan, dan hidrologinya, memengaruhi persebaran candi di sana. Teknik pengumpulan data berupa survei lapangan, studi peta, dan studi pustaka. Pengolahan dan analisis data didukung oleh perangkat lunak sistem informasi geografis. Hasil penelitian memperlihatkan bahwa masyarakat kuno di wilayah selatan Gunung Kelud pada umumnya menempatkan candi di wilayah berpotensi besar mendukung kehidupan manusia, sebaliknya mendirikan lebih sedikit candi di wilayah yang potensinya lebih kecil. Daerah yang potensinya sangat terbatas kurang diprioritaskan untuk pendirian candi. Potensi wilayah yang ditempati mayoritas candi mendukung kebutuhan hidup masyarakat dan memenuhi syarat umum pemilihan lahan kuil, yaitu lahannya subur dan dekat sumber daya air.

A Systematic Literature Review on The Role of LSTM Networks in Capturing Temporal Dependencies in Data Mining Algorithms
Authors: Raghuvanshi Kunal P.
Published: October 2024

Data mining plays a crucial role in extracting meaningful insights from large and complex data sets, with broad applications in sectors like finance, health care, and market analysis. Traditional techniques—such as classification, clustering, association rule mining, regression, and anomaly detection—are effective for analyzing structured data but struggle with sequential data due to the challenges of modeling temporal dependencies. Long Short Term Memory (LSTM) networks, a specialized form of Recurrent Neural Networks (RNNs), provide a solution to these challenges. By incorporating memory cells and gating mechanisms, LSTM effectively manage long-term dependencies and address issues like vanishing and exploding gradients. This paper reviews the impact of LSTM networks on data mining, analyzing over 60 key publications. By synthesizing concepts and recent advancements, the review underscores how LSTMs enhance the ability of data mining algorithms to capture and predict temporal patterns, reflecting current research trends and innovations

Multi-Objective Portfolio Optimization Using Hybrid Ant Colony Optimization and Compromise Programming
Authors: Rahmalia Dinita , Husenti Nadya
Published: October 2024

The increasing complexity of stock trading requires effective portfolio management to optimize returns while minimizing risks. Portfolio selection is critical in determining the most suitable combination of stocks, aiming to maximize expected returns and minimize risk within a given investment limit. This study constructs a mathematical model for portfolio optimization using six different stocks, incorporating constraints such as expected return, risk, and available investment. Given the multi-objective nature of the problem, a hybrid approach is proposed, combining Compromise Programming (CP), Nadir Compromise Programming (NCP), and Ant Colony Optimization (ACO) to address both minimization and maximization objectives. The ACO algorithm is applied to minimize deviation variables, which serve as the fitness function in the optimization process. The results demonstrate the effectiveness of the hybrid method in selecting portfolios that achieve minimal deviation, providing an optimal balance between risk and return. This research offers valuable insights for investors by illustrating the trade-offs between risk and reward in stock selection, contributing to more informed decision-making in portfolio management.

Authors: Puji Ari Andriyas
Published: October 2024

Supply chains play a critical role in the operational success of organizations, impacting both costs and product quality. However, they are often exposed to various risks that can disrupt business processes. This research aims to identify supply chain risks and propose mitigation strategies using the House of Risk (HOR) and Multi-Objective Optimization on the Basis of Ratio Analysis (MOORA) methods. Through interviews, key issues were identified in a fiberglass company's supply chain, including raw material supply fluctuations, procurement cost variability, defective materials, inappropriate specifications, outdated technology, insufficient worker skills, and ambitious company targets. The novelty of this study lies in the application of MOORA, which introduces a correlation matrix for risk mitigation by considering both cost minimization and benefit maximization. The analysis identified 12 risk agents and 26 risk events, which were prioritized using HOR stage 2 with the MOORA method. The top preventive actions were ranked, providing actionable recommendations for companies to address supply chain risks more effectively. The findings of this research offer practical insights for companies in the fiberglass industry to enhance supply chain resilience by integrating cost and benefit considerations into their risk management strategies.

Çalışmanın amacı, bireylerin sigarayı bırakma niyetinde egzersize yönelik sağlık inançlarının etkisini belirlemektir. Bu amaç doğrultusunda araştırmada ilişkisel tarama modeli kullanılmıştır. Araştırma grubunu, basit örnekleme yöntemiyle belirlenen 291 (150 erkek, 141 kadın) birey oluşturmuştur. Araştırmada, “Kişisel Bilgi Formu, “Sigarayı Bırakma Niyeti Ölçeği” ve “Egzersize Yönelik Sağlık İnançları Tutum Ölçeği” kullanılmıştır. Katılımcıların demografik özelliklerine göre sigarayı bırakma niyetleri ile egzersize yönelik sağlık inanç düzeylerini değerlendirmek için, T-Test ve ANOVA testi uygulanmıştır. Ayrıca ölçekler arasındaki ilişkiyi incelemek için oluşturulan araştırma modeli Yapısal Eşitlik Modeli (YEM) testiyle değerlendirilmiştir. Araştırma bulgusu T-Testi sonuçlarına göre, cinsiyet ile sigaranın zararlı olma düşüncesi değişkenlerinde anlamlı farklılıklar olduğu belirlenmiştir. Ayrıca YEM analizi sonuçlarına göre, egzersize yönelik sağlık inançları tutumu ve sigarayı bırakma niyeti arasındaki yol kat sayısı istatistiksel olarak anlamlı bulunmuştur. Sonuç olarak, egzersize yönelik sağlık inançları tutumu ve sigarayı bırakma bireylerin bazı demografik özelliklerine göre farklılaştığı ve bireylerin sigarayı bırakma niyetlerinin egzersize yönelik sağlık inançları tutumundan etkilendiği söylenebilir.
Dementia in Focus: Interdisciplinary Research Tasks in Latvia

Dementia is a characteristic symptom of several diseases, but mainly Alzheimer’s disease. There are also characteristic manifestations of the disease in the affected person’s use of language and communication with others. The social problems faced by people with dementia and their relatives are increasingly being highlighted in the Latvian public discourse. At the same time, the importance of this issue has been recognized in the fields of medicine and care. It can be concluded that a solution to dementia patient support requires cooperation between several disciplines of science at different levels, because individual institutional initiatives, although a positive endeavour, cannot fully contribute to the theoretical and practical solution of this complex problem in Latvia.

Tässä artikkelissa kerrotaan muistisairaiden ja heidän läheistensä tukemisesta Suomessa keskittyen sensitiiviseen muistityöhön maahanmuuttajien kanssa. Suomen sosiaali- ja terveydenhuoltojärjestelmä korostaa yksilöiden oikeutta hoitoon, mutta kielitaustoista johtuvat esteet vaativat erityishuomiota. Silti, eri kieli- ja kulttuuriryhmillä on isoja haasteita, kuten viivästyneitä diagnooseja ja kulttuurisia tabuja muistisairauteen liittyen. Muistiliitto ry ja Kulttuurinen Moninaisuus-Muistikeskus ry (MUKES) esittelevät hankkeitaan, jotka pyrkivät tukemaan kielistä ja kulttuurista moninaisuutta muistihoidossa. Muistiopas- ja Jututtaja -hankkeiden tavoitteena on voimaannuttaa eri kieli- ja kulttuuriryhmiä kouluttamalla vapaaehtoisia muistioppaiksi ja puhelinkumppaneiksi. Ne korostavat kulttuurisen kompetenssin ja joustavuuden tärkeyttä. Myös jatkuvaa kehitystä, koulutusta ja yhteistyötä tarvitaan lisäämän yhteiskunnallista ymmärrystä ikääntyvän väestön moninaisuudesta Suomessa.

Straipsnio tema yra susijusi su sindromu, vadinamu demencija, kurio metu pablogėja pažintinės funkcijos, t. y. gebėjimas mąstyti. Keičiantis socialinei ir demografinei situacijai pasaulyje, kartu didėjant vyresnio amžiaus žmonių skaičiui, demencija tapo viena opiausių mūsų laikų problemų. Tyrimo tikslas – parodyti, kaip demencijos pavadinimai vartojami Vokietijos ir Lietuvos žiniasklaidoje, ir aptarti, kokius terminus reikėtų vartoti kalbant apie žmones, kuriems diagnozuota demencija, kad jie nesukeltų neigiamų emocijų bei neskaudintų žmonių, kurie gyvena su demencija. Empirinio tyrimo pagrindą sudaro demencijos pavadinimų sąrašai, pateikiami kalbėjimo apie demenciją gairėse vokiečių ir lietuvių kalba. Šių pavadinimų vartojimas žiniasklaidos tekstuose nagrinėjamas remiantis tekstynu, kurį sudaro 110 straipsnių (55 lietuvių ir 55 vokiečių kalba) demencijos tema, publikuotų nuo 2016 m. iki 2022 m. Tekstyno lietuvių kalba tekstai surinkti iš Lietuvos naujienų portalų delfi.lt, 15min.lt, lrytas.lt ir alfa.lt. Vokiški straipsniai tyrimui paimti iš Vokietijos naujienų portalų FAZ.net, Sueddeutsche.de ir Zeit.de. Nagrinėjami straipsniai apima įvairius teksto žanrus, tačiau juos sieja bendra demencijos tema. Analizė atlikta naudojant AntConc įrankį, kurio pagalba nustatytas rekomenduojamų ir nerekomenduojamų žodžių bei žodžių junginių vartojimo dažnis žiniasklaidos tekstuose apie demenciją. Analizės rezultatai pateikiami diagramų ir lentelių pavidalu. Atlikta analizė rodo, kad nagrinėtuose tekstuose ir lietuvių, ir vokiečių kalba dominuoja žodžiai ir žodžių junginiai, kuriuos rekomenduojama vartoti rašant demencijos tema, žodžių bei žodžių junginių, kurie priskiriami prie nerekomenduojamų, vartojama nedaug.
INVESTIGATION OF WETTABILITY, ANTIBACTERIAL ACTIVITY, THERMAL INSULATION, AND MECHANICAL CHARACTERISTICS OF ELASTOMER BLEND ADHESIVES WITH HIGH-DENSITY FIBERBOARD WOOD AND ALUMINUM
Authors: Majeed Maha , Hussein Seenaa

Attention has recently been given to finding alternative and sustainable raw material sources for wood and metal adhesives, such as polyvinyl alcohol (PVA), corn starch (CS), arabic gum (AG), and dextrins (D). Modifying polymer dispersion using unique substances, such as modifying reactive elastomer liquid (EL) using PVA, CS, AG, or D results in sufficiently moisture-resistant adhesive joins. In the present study, the physical characteristics of EL/blended with the natural polymers PVA, CS, AG, and D, based on high-density fiberboard (HDF) wood and aluminum (Al) adhesives and coatings, were investigated and compared to those of pure EL. The EL was blended with PVA, CS, AG, or D at a ratio of 60/40 (w/w) to form EL/blends. The chemical structures, surface and interface morphology, adhesion strengths (including shear strength and pull-off strength), surface roughness, wettings, color intensity, and thermal insulation of the prepared EL and EL/blends were investigated. A scanning electron microscopy (SEM) investigation confirmed filler dispersion and adhesion between the blends, and coated HDF wood, or Al. The developed EL/AG blend had a pull-off strength of 144±5 and 102±3 MPa and a shear strength of 771±11, and 52±3 N with HDF wood and Al substrate, respectively. The EL/PVA blend had a maximum surface roughness value 4.57 µm, and its average water contact angle (WCA) was 85.6°. A plasma jet was used to treat the surface roughness and hence the wettability of the pure EL and the EL/blends, for example, plasma treatment decreased the roughness of the EL/AG blend from 4.36 to 3.28 μm. WCA, and hence wettability, was also significantly influenced by plasma treatment, for example, plasma treatment decreased the WCA of the pure EL from 71.7±0.4° to 30.7±0.7°. The lightness value of the EL/blends was less than that of the pure EL, indicating that (the color adhesives have darkened). Similarly, the yellowness-blueness and redness-greenness values of the EL/blends were greater than those of the pure EL,( rendering the blended adhesives more reddish and bluish). The EL/AG blend was found to have a minimum thermal conductivity (of 0.27 W/m.K), indicating maximum insulation.
