Published: February 2024

This study aims to find out the application of civic education in improving students' learning motivation on the material of Unity in Diversity in Elementary School. This type of research is descriptive with a qualitative approach. Qualitative research methods are used to deeply examine the research object without trying to manipulate the research, but rather studying a phenomenon. The results of the research on fifth grade students show that there are still some students who are less motivated in learning civic education, especially in the material of Unity in Diversity, because they have difficulty understanding the teacher's explanation. Learning about Unity in Diversity is expected to create an attitude of mutual respect among students so that they can apply it in daily life and increase student motivation through the use of more active and enthusiastic learning media. Teachers also face difficulties due to the lack of creative and innovative learning media, where they only rely on material from textbooks, making it difficult for students to understand Unity in Diversity in daily life.

Authors: Duratussania Firda Ditya , Halimatussa’diyah Della , Alpian Yayan
Published: February 2024

Ecobrick is one of the creative ways to manage plastic waste and turn it into useful objects, reducing pollution and toxins caused by plastic waste. The function of ecobrick is not to destroy plastic waste, but to extend the life of the plastics and process them into something useful, which can be used for the benefit of people in general. Ecobrick is a waste management technique made from used plastic bottles filled with clean plastic waste until full, then compacted until it becomes hard. After the bottles are full and hard, they can be assembled with glue. These assembled bottles can be turned into tables, simple chairs, building materials for walls, towers, small stages, and even potentially assembled into fences and foundations for simple playgrounds. The utilization of plastic waste at SDN Kondangjaya III is through the making of ecobricks. This activity is due to problems related to plastic waste, such as the abundance of waste in the school environment that has not been utilized, the presence of a specific plastic bottle waste bin in the school environment that is not being utilized, and the lack of understanding and knowledge in waste management to be utilized into something useful. From these various problems, it can be concluded that many elementary school students have not learned to recycle waste. The methods used are observation, demonstration, and direct practice in making ecobricks. The result of this activity is an increase in knowledge and understanding about the utilization of plastic waste and an improvement in the skills and creativity of students in managing plastic waste into useful objects.

The method of preaching has changed over time. Written sermons are now more important and effective than oral sermons, especially in works that contain preaching messages and social media. This is in line with the saying of the Prophet Muhammad, "Indeed, the ink of the scholars is better than the blood of the martyrs," which shows that the content of preaching will not be lost even if the preacher or writer has passed away. This study aims to analyze the impact of media on the growth of Islamic preaching. The research strategy uses a qualitative method based on field data. When Allah SWT says in the Qur'an, Saba':28, "And We have not sent you, [O Muhammad], except as a bringer of good tidings and a warner to all mankind, but most of the people do not know," it is clear that He obliges preaching to others. The results of the study in this paper show that the use of mass media as a channel for preaching offers benefits, demonstrating the importance of media involvement in spreading religious beliefs among the public.

Authors: Singh Swati , Pawar Rajat , Patidar Sunita
Published: February 2024

The oral route is one of the most important routes for local and systemic drug delivery due to its large surface area, high permeability and blood flow. Mouth dissolving films are the most advanced oral forms as they are simpler and easier to use than other dosage forms such as Oro-soluble tablets, sublingual tablets. Fast dissolving drug delivery system were rapidly developed in the 1970s as an alternative to capsules, syrups, and tablets for adults and adolescents who have difficulty swallowing conventional oral solid dosage form. The Oro- soluble film dissolves and disintegrates in less than a minute when placed in the mouth without drinking water or chewing. This form allows the drug to skip first-pass metabolism, which improve the bioavailability of the drug. This article provides a comprehensive review on mechanism of action, merits, formulation, evaluation and covering the aspects related to novel fast dissolving techniques.

Published: February 2024

Do những lợi ích về kinh tế, kỹ thuật và môi trường nên việc sử dụng vật liệu mặt đường asphalt cũ (Reclaimed Asphalt Pavement-RAP) để sản xuất bê tông asphalt tái chế đang ngày càng phổ biến trên thế giới trong thời gian gần đây. Khi sử dụng với hàm lượng RAP thấp (từ 10% đến 20%), các tính năng của bê tông asphalt có RAP có sự khác biệt không đáng kể so với hỗn hợp không có RAP. Tuy nhiên, đối với hỗn hợp asphalt sử dụng hàm lượng RAP cao (> 25%), các tính năng có sự khác biệt đáng kể và có thể ảnh hưởng đến chất lượng của mặt đường bê tông asphalt. Bài báo trình bày nghiên cứu ảnh hưởng của hàm lượng RAP đến tính năng kháng nứt và kháng hằn lún của bê tông asphalt tái chế nóng. Ba hỗn hợp asphalt được đánh giá bao gồm hỗn hợp đối chứng (0%RAP), hỗn hợp sử dụng 30%RAP và 50%RAP. Thí nghiệm Hamburg Wheel Tracking Test (HWTT) được sử dụng để đánh giá sức kháng hằn lún vệt bánh xe theo tiêu chuẩn AASHTO T324. Trong khi đó, mô hình thí nghiệm kéo gián tiếp (Indirect Tensile Asphalt Cracking Test (IDEAL-CT)) được thực hiện để xác định khả năng kháng nứt theo tiêu chuẩn ASTM D8225. Kết quả nghiên cứu chỉ ra rằng, khi gia tăng hàm lượng RAP trong hỗn hợp, sức kháng hằn lún được cải thiện nhưng có sự giảm đáng kể khả năng kháng nứt. Chiều sâu lún vệt hằn bánh xe của hỗn hợp asphalt sử dụng 30% RAP và 50% RAP giảm tương ứng 24,2% và 41,5% so với hỗn hợp đối chứng không có RAP nhưng chỉ số kháng nứt CTIndex giảm 60,8% và 63,1% tương ứng. Chỉ số kháng nứt của hỗn hợp sử dụng 50%RAP thấp hơn ngưỡng tối thiểu là 70 theo báo cáo của Bang Virgina, Mỹ

The Flow State Scale for Rehabilitation Tasks: A New Flow Experience Questionnaire for Stroke Patients
Authors: Ottiger Beatrice , Veerbeek Janne Marieke , Cazzoli Dario , Nyffeler Thomas , Vanbellingen Tim
Published: February 2024

Importance: Flow can be described as a subjective state that people report when they fully engage in an activity and experience pleasure, satisfaction, and enjoyment. Flow experiences are measured to determine the extent to which patients engage in therapy activities. Several flow questionnaires are used in neurorehabilitation. However, none have been validated for patients with (sub)acute stroke.

Objective: To develop and validate a new flow questionnaire for patients with (sub)acute stroke.

Design: Single-center prospective cohort study.

Setting: Neurorehabilitation unit of the Neurocenter of the Luzerner Kantonsspital in Lucerne, Switzerland.

Participants: Fifty patients with (sub)acute stroke.

Outcomes and Measures: Development of the Flow State Scale for Rehabilitation Tasks (FSSRT) and determination of the psychometric properties of the FSSRT (internal consistency, test–retest reliability, structural and construct validity) in (sub)acute stroke patients.

Results: The FSSRT showed good internal consistency and excellent test–retest reliability. Composed of four components—concentration, pleasure, movement control, and absorption—the FSSRT correlated significantly negatively with the Hospital Anxiety and Depression Scale, indicating good divergent validity.

Conclusions and Relevance: The FSSRT is a reliable and valid questionnaire measuring flow experience in patients with (sub)acute stroke. This questionnaire can be easily used in occupational therapy as well as in physical therapy and gives therapists important information about the flow experience of patients during therapy to adjust the therapy accordingly.

Glaucoma is a degenerative optic neuropathy leading to characteristic optic nerve head features, alternations in retinal nerve fiber layer thicknesses and visual field defects. Decrease of retinal sensitivity in the macular area is considered an important sign of glaucomatous damage. Accurate assessment of the function of the retina in macular region is possible thanks to microperimetry. Simultaneously, it is possible to evaluate the fixation behavior using the eye-tracking feature independent of eye movement and to correct gaze movements. To date, small number of studies have reported alternations in fixation stability in glaucoma eyes. The microperimetry test is reliable and reproducible. Microperimetry allowing for the assessment of changes in the central part of the field of view, both in qualitative and quantitative terms. Comparative studies on microperimetry and standard automated perimetry have shown that the reis a good quantitative correlation between the two devices in glaucoma. The usefulness of microperimetry in the management of glaucoma is currently the subject of research. The aim of this article is to review of clinical utility of microperimetry in patients of glaucoma.

Effectiveness of Concurrent Positive and Negative Visual Feedback on a Computerized Motor Task of Varying Difficulties
Authors: Ziv Gal , Odem Chen
Published: February 2024

The purpose of this online study was to examine the effectiveness of concurrent positive and negative visual feedback on the performance of a rotary-pursuit task. One hundred and nine physical education students were randomly assigned to three groups: a positive feedback group (n = 37), a negative feedback group (n = 35), and a control group (no feedback; n = 37). The students participated from their own home computers and performed an easy, moderate, and difficult rotary-pursuit task. On Day 1, the participants performed a pre-test with no feedback and practiced eight trials of each level of difficulty with the assigned feedback. On Day 2, they practiced eight trials of each level of difficulty again. On Day 3, they practiced eight trials of each level of difficulty with feedback and performed a post-test with no feedback. Finally, the participants were asked to report their subjective assessment of the task difficulty. The main findings were that in the task of moderate difficulty, negative feedback led to the best performance during practice. In addition, regardless of the difficulty level, practicing with negative feedback led to the best performance in the post-test. The results suggest that task difficulty moderates the effects of feedback on performance and that providing concurrent negative visual feedback in a continuous task may be more advantageous.

Published: February 2024

IIoT “Industrial Internet of Things” refers to a subset of Internet of Things technology designed for industrial processes and industrial environments. IIoT aims to make manufacturing facilities, energy systems, transportation networks, and other industrial systems smarter, more efficient and connected. IIoT aims to reduce costs, increase productivity, and support more sustainable operations by making industrial processes more efficient. In this context, the use of IIoT is increasing in production, energy, healthcare, transportation, and other sectors. IoT has become one of the fastest-growing and expanding areas in the history of information technology. Billions of devices communicate with the Internet of Things with almost no human intervention. IIoT consists of sophisticated analysis and processing structures that handle data generated by internet-connected machines. IIoT devices vary from sensors to complex industrial robots. Security measures such as patch management, access control, network monitoring, authentication, service isolation, encryption, unauthorized entry detection, and application security are implemented for IIoT networks and devices. However, these methods inherently contain security vulnerabilities. As deep learning (DL) and machine learning (ML) models have significantly advanced in recent years, they have also begun to be employed in advanced security methods for IoT systems. The primary objective of this systematic survey is to address research questions by discussing the advantages and disadvantages of DL and ML algorithms used in IoT security. The purpose and details of the models, dataset characteristics, performance measures, and approaches they are compared to are covered. In the final section, the shortcomings of the reviewed manuscripts are identified, and open issues in the literature are discussed.
Psicanálise e liderança num mundo transformado pela pandemia e pela guerra
Authors: Figueiredo Sofia
Published: February 2024

Nesta entrevista falamos sobre a contribuição da psicanálise para a liderança. As dimensões emocionais da liderança nos últimos dois anos atingiram amplitude máxima com a pandemia em 2020. Se antes podia haver uma ilusão sobre a eficácia de uma liderança arrogante e autoritária, atualmente o que se deseja é uma liderança confiável, próxima e autêntica. Agora, os melhores líderes querem pensar na complexidade das emoções de outra forma, e não existe uma resposta certa, e isso é, ou está em vias de ser, reconhecido. É sobre liderança que falamos na entrevista com Kerry Sulkowicz, presidente da Associação Psicanalítica Americana. A entrevista foi realizada à distância, entre Londres e Lisboa, em março de 2022. De que são feitos os melhores líderes e como a liderança em tempos tão catastróficos de pandemia e guerra pode ser decisiva na sobrevivência do grupo.

Abstract. Carbon cycling in the Amazon fundamentally depends on the functioning of ecosystems and atmospheric dynamics, which are highly intricate. Few studies have hitherto investigated or measured the radiative effects of aerosols on the Amazon and Cerrado. This study examines the effects of atmospheric aerosols on solar radiation and their effects on net ecosystem exchange (NEE) in an area of semideciduous tropical forest in the north of Mato Grosso. Our results show that for a relative irradiance (f) 1.10–0.67, a decrease in incident solar radiation is associated with a reduction in the NEE. However, an average increase of 25 %–110 % in NEE was observed when pollution levels and aerosol optical depth (AOD) were above ≈ 1.25 and f < 0.5. The increase NEE was attributed to the increase of up to 60 % in the diffuse fraction of photosynthetically active radiation. The change in AOD and f was mainly attributable to biomass burning organic aerosols from fires. Important influences on vapor pressure deficit (VPD) as well as air temperature (Tair) and canopy (LCT), induced by the interaction between solar radiation and high aerosol load in the observation area, were also noticed. On average, a cooling of about 3–4 ∘C was observed for Tair and LCT, and a decrease of up to 2–3 hPa was observed for VPD. Given the long-distance transport of aerosols emitted by burning biomass, significant changes in atmospheric optical properties and irradiance will impact the CO2 flux of semideciduous forests distributed in the region.

Abstract. There has been a steady increase of marine activity throughout the Arctic Ocean during the last decades, and maritime end users are requesting skillful high-resolution sea ice forecasts to ensure operational safety. Different studies have demonstrated the effectiveness of utilizing computationally lightweight deep learning models to predict sea ice properties in the Arctic. In this study, we utilize operational atmospheric forecasts as well as ice charts and sea ice concentration passive microwave observations as predictors to train a deep learning model with ice charts as the ground truth. The developed deep learning forecasting system can predict regional sea ice concentration at one kilometer resolution for 1 to 3-day lead time. We validate the deep learning system performance by evaluating the position of forecasted sea ice concentration contours at different concentration thresholds. It is shown that the deep learning forecasting system achieves a lower error for several sea ice concentration contours when compared against baseline-forecasts (persistence-forecasts and a linear trend), as well as two state-of-the-art dynamical sea ice forecasting systems (neXtSIM and Barents-2.5) for all considered lead times and seasons.
