Authors: Puspitasari Mardiana Dwi , Rahardja Mugia Bayu , Nurhayati Septi , Surbakti Indra Murty
Published: March 2024

Purpose: Maintaining functional ability and minimizing age-related disability of older adults are required to promote healthy aging. A supportive physical and social environment, in addition to individual variables, has a role in reducing the risk of age-related disability. Infrastructure development differs between Java-Bali and outer Java-Bali regions. This study aims to determine the extent to which the disability of older adults in Java-Bali and outer Java-Bali regions.

Methods: This study is cross-sectional, using data from the 2020 National Socio-Economic Survey (SUSENAS) with 122.344 Indonesian older adults aged 60 and over. Disability is the outcome variable. The explanatory variable is regional disparity (Java-Bali and outer Java-Bali regions), which refers to where the older adults live. In addition, the control variables include age, sex, marital status, educational level, employment status, leisure activity, household wealth status, and self-rated health status (SRHS). A multivariate logistic regression statistical analysis is performed.

Results: The outer Java-Bali region has a slightly greater prevalence of older adults with age-related disability than the Java-Bali region, with 28.8 and 22.9 percent, respectively. However, older adults living in the outer Java-Bali region are 1.63 times more likely (OR 1.63; 95% CI (1.58-1.68)) to have disability than those living in the Java-Bali region. Other socio-demographic variables are significantly associated with age-related disability.

Conclusion: Living in the Java-Bali region increases the risk of age-related disability. Infrastructure development in the outer Java-Bali region needs to be improved so that older adults can experience healthy aging.

Authors: Simanjuntak Saidah Fatimah Sari , Sipahutar Tiopan , Mafkul Martya Rahmaniati
Published: March 2024

Purpose: Rabies is a priority strategic disease because it has an impact on socio-economic and public health. This study aims to describe the incidence of rabies-transmitting animal bite cases in North Tapanuli Regency in 2016-2020, contribute to understanding the dynamics of cases, and provide effective information in controlling cases of animal bites that transmit rabies.

Methods: Ecological study using aggregated data. The data was collected from monthly reports of rabies cases at the North Tapanuli Regency Health Service in 2016-2020. As a unit analysis, all districts are used. QGIS and GeoDA software are used for data analysis. Through GeOda software, spatial autocorrelation analysis was carried out globally using Moran's I test and locally using the LISA test.

Results: Rabies-transmitting animal bite cases had a dispersed pattern in 2016 (IE[I]). Globally, there is positive spatial autocorrelation in rabies-transmitting animal bite cases between districts in North Tapanuli Regency in 2017 and 2020 (p-value < 0.05). Moran's cluster map shows that locally in 2016-2020, the districts in the quadrant I (High-High) are Siborongborong and Sipoholon. Quadrant II (Low-High) is Adiankoting and Pagaran. Quadrant III (Low-Low) is Pangaribuan, and quadrant IV (High-Low) is Pahae Jae and Pangaribuan.

Conclusion: Globally, cases of animal bites that transmit rabies in North Tapanuli Regency occur in clusters. It means that the number of bite cases in one area is related to the number of cases in other nearby areas. Therefore, rabies control program interventions in areas with high observation values must be prioritized so they do not spread to areas with low observation values.

Published: March 2024

Background: The quality of pharmacy education is stated in the literature to be one of the factors influencing the quality of self-medication services in pharmacies. However, research describing the ability of pharmacy students to handle self-medication cases is limited.Objectives: This study aims to describe pharmacy students’ recommendations for two vignette cases involving analgesic-antipyretics (i.e., primary dysmenorrhea and childhood fever cases) in an Indonesian university and to identify factors related to the appropriateness of their recommendations.Methods: Apothecary students were asked to provide recommendations and their reasoning for primary dysmenorrhea and childhood fever cases using a structured telephone interview.Results: Of the 86 participants, appropriate recommendations were provided by 86% and 78% for a case of primary dysmenorrhea and for childhood fever respectively. One-quarter of students did not identify referral criteria in the case of childhood fever and thus made inappropriate recommendations. Age and study period were factors significantly related to providing appropriate recommendations, in which students who were younger and completed their study program within 5 to 6 years were significantly able to provide appropriate recommendations compared to students who were older and whose study period exceeded 6 years.Conclusion: A considerable number of apothecary students in an Indonesian university were able to properly manage cases related to analgesic-antipyretic recommendations. Further qualitative research is needed to identify factors underlying the knowledge of Indonesian pharmacy students in identifying major and minor patient presentations.

THE CONCEPT OF HABITUS IN THE RESEARCH OF DIGITAL DIVIDES AND INEQUALITIES
Authors: Ristić Dušan , Kišjuhas Aleksej
Published: March 2024

In the paper, we discuss the relevance of the concept of habitus, developed by the French sociologist Pierre Bourdieu, in the research of social inequalities and divides in digital practices. We approach digitalisation as a field of practice and social inequality, in which social processes are deeply imbued with the mediation of technologies. We particularly emphasise dimensions and levels of digital inequalities and divides, including the first-level digital divide that points to Internet access, the second-level digital divide that aims to differentiate the binary inequalities of Internet access from inequalities in skills and uses, and the third-level digital divide that poses the question of inequalities in the outcomes of Internet use. We present relevant empirical studies, with the aim of testing our main hypothesis regarding the relevance of the concept of habitus as an adequate research tool in the field. We confirm the hypothesis, demonstrating that this concept has both theoretical and methodological significance in the research of digital divides and inequalities.
THE NEXUS BETWEEN TRADE INFRASTRUCTURE DEVELOPMENT AND EXPORT: THE CASE OF CENTRAL AND EASTERN EUROPEAN COUNTRIES
Authors: Bugarčić Filip , Mićić Vladimir , Bošković Gorica
Published: March 2024

The focus of economic policymakers in Central and Eastern European countries (CEEC) is on developing and improving national infrastructure, including roads, railways and other forms of physical infrastructure needed for the realisation of economic activities, with the primary goal being to create a favourable business environment for foreign investments and export intensification. The article aims to examine whether the development of infrastructure in these countries has contributed to the increase in exports and to what extent, which would likewise examine the justification of infrastructure investments as a part of the economic strategy and foreign trade policy. The method of panel regression analysis with fixed effects was applied, which confirms the positive and statistically significant impact of infrastructure on export, justifying the initiative for the development of national infrastructure in the observed countries. Based on the obtained results, valid conclusions have been drawn regarding the theoretical and practical implications of the research, which point to the importance of physical infrastructure development as one of the leading determinants for export incentives.
THE ROLE AND SIGNIFICANCE OF LIP-READING
Authors: Kovačević Tamara , Isaković Ljubica
Published: March 2024

Lip-reading is a complex psychophysiological process, which involves the visual perception of oral movements, their kinaesthetic memorisation, and the psychological act of recognising (identifying) words for their better understanding. The need of each person to supplement and clarify the received message is emphasised by the careful observation of the face and lips, especially in unfavourable environmental conditions. The main aim of the study is to point to the role, importance, specific features, and the benefits and limitations of lip-reading through the review of available literature. The methods of analysis and evaluation were applied to the relevant available literature. Numerous pieces of data on the characteristics, factors and features which affect lip-reading were obtained. Lip-reading, i.e. the ability to understand speech on the basis of observing the movements of speech organs is a very specific skill. It is one of the components of speech development, and it represents a part of the communication speech chain which comprises the speaker and the one who reads speech. It has a manifold application in the transcription of speech in cases when sound is not available. What can have a negative impact on the perception of speech is the possibility of sound and lip movements not being synchronised. It is of particular significance for deaf persons and persons hard of hearing who rely on this process fully in their everyday communication, which makes it easier for them to receive information from their surroundings. It enables their better communication, education, independence and coping in their daily functioning.

Published: March 2024

Abstract: Alzheimer’s disease (AD) is a neurodegenerative disorder characterized by progressive cognitive decline and memory impairment, leading to dementia and irreversible decline in cognitive abilities. This disease causes the person to suffer from memory loss, unusual behaviour, and language problems. The initial symptoms, such as episodic memory impairment and the navigational problem of the patient, are typical variants. In the proposed system we are using The Deep Learning Models as Modified CNN along with MobileNet, and VGG16 algorithms and classify the images as either Mild Demented or Moderate Demented or Non-Demented or Very Mild Demented. In this study we are using Augmented ADNI dataset which consists of 40000 images. This can be utilized in the future to classify the types of different classifications easily which is easy to find out the infections in initial stages and can be cured in the initial stages only.

Published: March 2024

The significance of a company’s ownership structure (OST) is reflected in how it impacts the process of making decisions and the allocation of profits within the organization. Based on that, this article aims to inspect the connection between OST and corporation performance (CP). The current study employed an empirical strategy that entailed the development of comprehensive ordinary least squares (OLS) measures, which were then applied to a sample of 199 financial and non-financial firms listed on the Saudi market between the years 2015 and 2021, amounting to a total of 1393 observations. The statistical findings supported the impact of managerial ownership (MGOW), institutional ownership (INOW) and government ownership (GOOW) on CP. On the contrary, foreign ownership (FOOW) and ownership concentration (OWCO) have a negatively significant relationship with CP. This article is one of the few empirical studies that look at how OST affects CP. In addition, it is the first study in the Kingdom of Saudi Arabia (KSA) that examines the impact of the OST components (administrative, institutional, foreign, governmental ownership, and ownership concentration) on the performance of companies in all sectors of financial and non-financial companies.

Published: March 2024

Abstract The risk factors and clinical prediction of cardiovascular
disease comorbidities in patients with breast cancer have not been fully
clarified. We conducted this retrospective case-control study. The
univariable and multivariable cox regression was used to screen the risk
factors of cardiovascular comorbidities in breast cancer patients, and
construct a clinical prediction model, followed by prediction efficacy
test and internal validation. A total of 144 cases were included and
divided into two groups based on the low and high expression levels of
apoB (n=46 in apoBlow and n=98 in apoBhigh group). Univariable and
multivariable cox regression found that apoB, age and HER2 were the key
factors responsible for the myocardial ischemia occurrence in breast
cancer patients. These factors were used to constructed the clinical
prediction model with combination area under curve (AUC) of 0.583, and
the decision curve analysis (DCA) suggested that there would be
therapeutically clinical net benefit in the model-predicted population
in the predicted threshold interval between 0.35 to 0.70. Finally,
Kaplan-meier plot indicated HER2(+) category and apoBhigh lead to the
most occurrence of myocardial ischemia in breast cancer patients.
Moreover, the 3-year disease-free survival (DFS) was not found
difference between the apoBlow and apoBhigh subgroups. The clinical
prediction model was constructed using three key factors, and it was
indicated HER2(+) and apoBhigh lead to the most occurrence of myocardial
ischemia in breast cancer patients. This study may be helpful in
providing clinical evidence for the early prediction of cardiovascular
comorbidities in breast cancer patients.

Authors: Namba Mira , Kaneda Yudai , Takebayashi Masaki
Published: March 2024

Plastic pollution is increasingly becoming a threatening problem
worldwide, with highlighted health risks associated with plastic waste
incineration. Among the immediate measures to address this problem,
proper recycling of PET bottles stands out as a pertinent strategy.
Considering the urgent need for administrative-led reforms, we assessed
the separation rates of PET bottle caps and labels in a government
office in Japan, which revealed a concerning fact; only 59.3% had both
caps and labels removed and properly separated. Thus, one potential
solution is the use of Nudges, which are effective methods for promoting
behaviors such as healthy actions. Since both health and environmentally
conscious behaviors involve choices across different time points,
leveraging insights from Nudges developed in the field of health
behavior to environmental behaviors are considered crucial even from a
health promotion perspective.

Authors: MG Muzzi
Published: March 2024

Glaucoma is a group of eye diseases which result in damage to the optic nerve and vision loss. Glaucoma can be divided in two groups’ open-angle and closed-angle. The importance in glaucoma disease is to treat it early because vision loss from this pathology, once it has occurred, is permanent. The main risk of factors for glaucoma includes increased pressure in the eye, a family history of the condition and high blood pressure . Generally, it is possible to treat glaucoma with laser and this treatment may be affective in both open-angle and closed-angle. A number of types of glaucoma surgeries may be used in people who do not sufficiently respond to other measure and treatment of closed-angle glaucoma is a medical emergency. After the laser treatment, if the ophthalmologist gives permission, it is possible to fit contact lenses to achieve better vision or correct patients with spectacles. This case report shows the fitting of rigid gas permeable progressive bitoric lenses after laser treatment because visual acuity achieved with spectacles was not good. Due to the intervention and patient needs, it was not possible to fit a scleral or hybrid lens.

Perilaku hidup bersih dan sehat (PHBS) adalah sekumpulan perilaku yang dipraktikkan atas dasar kasadaran sebagai hasil pembelajaran yang menjadikan seseorang atau keluarga dapat menolong diri sendiri dan bidang kesehatan dan berperan aktif dalam mewujudkan kesehatan masyarakat. Derajat kesehatan anak dan remaja pada saat ini belum bisa dikatakan baik, karena masih banyak terdapat masalah kesehatan khususnya pada remaja. Dampak dari kurang dilaksanakan PHBS diantaranya yaitu suasana belajar yang tidak mendukung karena lingkungan sekolah yang kotor, menurunya semangat dan prestasi belajar disekolah, menurunkan citra sekolah di masyarakat umum. Ruang kelas yang kotor, maraknya jajanan tidak sehat serta tempat pembuangan sampah yang tidak tertata akan menyebabkan munculnya berbagai macam penyakit. Salah satu penyebab rendahnya nilai PHBS di sekolah adalah karena kurangnya pengetahuan Remaja akan pentingnya hidup bersih dan sehat, pengetahuan yang dimiliki remaja akan mempengaruhi sikap Remaja tentang situasi lingkungan di sekitarnya.Berdasarkan hal tersebut, maka sangat penting untuk dilakukan penyuluhan mengenai Perilaku Hiup Bersih dan sehat (PHBS) di sekolah sebagai bekal mereka untuk mencegah terjadinya penyebaran penyakit. Dengan kegiatan penyuluhan mengenai PHBS bertujuan meningkatkan pengetahuan mengenai Perilaku Hidup Bersih dan Sehat (PHBS) pada remaja. Penyuluhan PHBS sangat penting untuk meningkatkan derajat kesehatan di sekolah, penerapan PHBS di sekolah sangat bermanfaat dalam kebiasaan sehari-hari dapat mencegah kerentanan timbulnya penyakit, tentunya juga bermanfaat dalam meningkatkan kualitas pembelajaran di kelas karena fisik yang sehat pada pelajar, sehingga para pelajar tidak lemas saat mengikuti kegiatan pembelajaran

Penyimpangan-penyimpangan yang terjadi di kalangan remaja dan pelajar seperti tidak pernah usai, mulai dari bullying, kekerasan sosial sampai dengan penyalahgunaan narkoba. Komisi Perlindungan Anak Indonesia (KPAI) merilis data bahwa sepanjang tahun 2022, setidaknya sudah terdapat lebih dari 226 kasus kekerasan fisik dan psikis, termasuk perundungan yang jumlahnya terus meningkat. Kasus kekerasan seksual terhadap anak di Indonesia cukup juga tinggi. Penyebab adanya tren tersebut adalah banyak remaja yang terpengaruh lingkungan yang tidak sehat sehingga terlibat kepada pergaulan bebas. Pergaulan bebas dapat menyebabkan penyimpangan norma seperti kekerasan seksual, tawuran dan penyalahgunaan narkoba. Salah satu upaya untuk mencegah dan menanggulangi pergaulan bebas adalah dengan pendidikan karakter. Maka dari itu tujuan PKM ini adalah mensosialisasi dan mendampingi para pelajar khususnya SMAN 9 Bandar Lampung untuk memahami bahayanya pergaulan di lingkungan yang sangat bebas. Kemudian sasaran dari kegiatan ini adalah siswa SMAN 9 Bandar Lampung. Pengabdian ini akan dilaksanakan dengan memberi pemahaman betapa bahayanya pergaulan bebas yang dapat menimbulkan penyimpangan norma seperti kekerasan seksual, tawuran dan penyalahgunaan narkoba. Kegiatan ini juga memberi pelatihan bagaimana siswa SMA dapat menanamkan nilai dan karakter pancasila pada diri masing-masing. Evaluasi kegiatan dilakukan dengan mengisi kuesioner (tes angket). PKM ini melakukan pre-test dan post test.

Analogous Charging Effect of Surfactant-Pesticide Spray Jet on Droplet Characteristics and Deposition on Hydrophobic Leaf Surfaces
Authors: Appah Samuel , Amoah Asante Eric , Amigangre Ayambire Christopher
Published: March 2024

An induction charging principle had been applied to enhance spray droplet characteristics and quantity deposition on hydrophobic abaxial-adaxial leaf surfaces from pesticide EC Glyphosate [C3H8NO5P] and surfactant Silwet L-77 [C13H34O4Si3] formulations. A nozzle cap containing two electrodes (spacing at 9 mm apart) was used to superpose charges to spray droplets under applied voltages of 2–12 kV in an electric field (E) of 8.9 × 105 V/m. From a tee-jet flat fan (TP11004VS) nozzle tip fitted into the electrode cap and positioned at 60 cm high above targeted Brassica campestris leave surfaces, the spray droplets were directed onto the leaves at a liquid flow pressure of 4 bar and travelling speed of 2 m/s. The measurements were done using Keithsley picoammeter to quantify spray chargeability (CMR), droplet sizes by lesser particle size analyzer (LPSA) and deposition on leaf surfaces by high-speed camera. In effect, droplet sizes of EC, L-77 and EC + L-77 decreased with an increasing applied voltage. The CMR of L-77 was lower than EC and highest for EC + L-77 composite solution. Based on Image analysis of droplets density per leaf area, maximum exposure of adaxial leaf surfaces intercepted many charged spray droplets than abaxial surfaces. As regressed, the quantity of charged spray deposition from EC + L-77 formulation was highest at both adaxial (approx. 27.44 Qd/cm2) and abaxial (approx. 5.57 Qd/cm2) hydrophobic leaf surfaces than EC of 26.12: 3.19 Qd/cm2 and L-77 of 24.80: 2.53 Qd/cm2, respectively. Also, contact angle, Theta E, of charged spray droplets was smaller than Theta C on adaxial than abaxial leave surfaces, a phenomenon attributed to high chemo-electrical properties of formulations that aided the direct flight, coiling and deposition of droplets in order of EC > EC + L-77 > L-77. Generally, there was no observable droplet rebound; hence, surfactant-pesticide composite spraying is considered suitable for electrostatic application in plant protection technology. Therefore, for effective application, charged droplets from glyphosate EC in silwet L-77 solution should be recommended, as it provides optimum droplet sizes, chargeability, contact angle and deposition on hydrophobic leave surfaces.

Penggunaan metode soybean crude urease calcite precipitation (SCU-CP) untuk perbaikan tanah menghasilkan produk sampingan berupa amonia, yang jika nilainya tinggi dapat memberikan dampak buruk pada lingkungan. Penelitian ini menggunakan zeolite, arang aktif, dan karang sebagai bahan penyerap amonia. Tujuan penelitian ini adalah mengetahui bahan yang paling efektif dalam penyerapan amonia dan pengaruhnya saat diaplikasikan pada tanah. Pengujian dilakukan menggunakan dua konsentrasi dan tiga waktu pengadukan untuk semua bahan penyerap. Hasil pengujian menunjukkan penyerapan amonia terbesar terjadi pada arang aktif dengan konsentrasi 0,1 g/ml dan waktu pengadukan 20 menit, dengan nilai penyerapan 62%. Arang aktif disimpulkan memiliki efektivitas penyerapan amonia terbaik dibandingkan dengan zeolite dan karang. Penyiraman larutan aquades sebanyak 5 PV pada sampel dengan arang aktif menghasilkan nilai konsentrasi amonia terkecil sebesar 0,00001500 g/ml yang belum memenuhi baku mutu. Efektivitas penyerapan total yang terukur setelah dilakukan penyiraman pada tanah adalah sebesar 99% dari konsentrasi amonia kontrol. Penggunaan arang aktif terbukti efektif untuk mengurangi konsentrasi amonia saat larutan SCU-CP diaplikasikan pada tanah, meskipun nilainya belum memenuhi baku mutu.

Taking notes are important activities that students need to do while following the mathematics learning process. The notes will be useful to them as relevant guidelines to help complete the task or prepare for the exam. However, many learners do not take notes in mathematics learning. This is due to their lack of awareness of the benefits of notes in learning. One of the tips that can be done to overcome this is to take notes with mind mapping techniques. Mind mapping is a way of recording creatively, effectively and not boringly because in making it students are facilitated to express their thoughts / abilities and imagination to use various newly learned words / terms, symbols / images, and colors, so that the ideas mapped will last a long time in their memory. This is different from ordinary notes that are only in the form of narratives. This research has facilitated class XI mipa students of SMAN 8 Padang to make notes with mind mapping techniques. As a result, the ability to make mathematical mind mapping for students is in the sufficient category.  Keywords– Mind Mapping, Mathematics Learning.
