Abstract
 
Keude Bieng Village, which is located on Jalan Meulaboh-Banda Aceh, precisely in Lhoknga District, Aceh Besar Regency, is a tourist area that is very popular with tourists. However, most of the residents along Lhoknga Road opened stalls for visiting tourists. They also produce various typical Acehnese foods and produce various rattan craft skills which are part of micro, small and medium enterprises (MSMEs). The rattan and other bamboo craftsmen who sell along the street of Keude Bieng create economic activity for the community. However, in this modern digital era, many MSMEs still find it difficult to use digital marketing media, so not many people use it. Based on these problems, digital marketing outreach and training, especially the TikTok Shop Application, was carried out for MSME business actors in Keude Bieng Village, Lhoknga District, Aceh Besar Regency. The choice of marketing media using TikTok is because TikTok is currently an application that is loved by the public and the benefits are felt and also its influence on purchasing a product marketed on the application with the aim that MSMEs who use the application can promote and sell products. The aim of carrying out this Community Service activity is to optimize marketing activities for MSMEs digitally so that MSME products in Keude Bieng Village, Lhoknga District, Aceh Besar Regency can cover a wider scope. Community Service Activities in Keude Bieng Village are carried out by holding outreach and training for all MSME players. Based on the activities that have been carried out, MSMEs who do not yet have a TikTok Shop account can be helped to manage the products produced on the platform and understand how to market them. The results of the community service program for MSMEs in Keude Bieng Village, Lhoknga District, Aceh Besar Regency, had a positive impact on those who took part. This is evidenced by increases in knowledge, skills and product quality, number, type and turnover, management capabilities, profits and the number of new entrepreneurs.

Authors: Hutsol A. V. , Dmytruk I. V. , Dmytruk L. I.
Published: August 2024

Purpose. To investigate the effect of probiotic preparations on the digestibility of young pig rations. Methods. Zootechnical analysis, experiment and method of analogue groups. Results. Calculations showed that, on average, the piglets of the second and third experimental groups digested more of the nitrogen consumed with feed by 0.98 g and 2.26 g, respectively, than the young pigs of the control group. The average amount of nitrogen absorbed in the body and consumed with feed was greater in pigs of the second experimental group by 0.56 g, or 4.23%, in the third experimental group - by 3.48 g, or 26.3%. The highest level of assimilation of nitrogen from ingested and digested in piglets of the third experimental group was 9.43% and 8.26%, respectively. It was established that the average daily weight gain in piglets of the first control group was 550 g, in the second experimental group - 567 g (17 g, or 3.1%, more), in the third experimental group - 613 g (63 g, or 11.5%, more). The difference between the control and the third experimental group is not statistically significant, but there is a tendency to the increased gains in the third group. It was determined that the coefficient of digestibility of nutrients in piglets of the second experimental group is higher: as to dry matter – by 2.3%, organic matter – by 2.1%, protein – by 2.73%, fat – by 2.81%, fiber – by 0.83%, BER – by 2.32%. The third research group has higher indicators of: dry matter – by 5.11%, organic matter – by 4.86%, protein – by 5.82%, fat – by 4.31%, fiber – by 4.54%, BER – by 4.05% compared to the control group. The difference is not significant, but there is a tendency to increase in the digestibility coefficients in the third group that received subtiform probiotic (400 g/t). Conclusions. Probiotic preparations have a positive effect on the digestibility of nutrients in the diets of young pigs.

Purpose. To study the productivity of weaning young pigs when fed with Nutrimin premix as part of compound feed. In order to realize the set goal, it is necessary to develop a compound feed starter with Nutrimin premix and to investigate the effect of feeding it on the productivity of weaning pigs. Methods. In the process of the research, general scientific methods were used: deduction, scientific hypothesis and abstraction. The method of zootechnical analysis was used to conduct laboratory research. The main experimental method was the method of similar groups. Variational statistics methods were used to process the obtained experimental results. Results. The efficiency of pork production and its quality largely depends on the quality of feeds. High productivity cannot be achieved without enriching diets with the required amount of nutrients and biologically active substances. Biologically active substances are added to compound feed in the form of premixes. The weaning pigs were fed with the newly created combined starter feed of the following structure: barley – 15%, wheat – 37%, triticale – 15%, soybean meal – 29%, Nutrimin premix – 4%. The nutritional value of the compound feed was 2.22 IU and 243 g of digestible protein. The use of Nutrimin premix in the feeding of young pigs as part of compound feed contributed to the increase in average daily gains by 78.8 g, or by 12.3%, compared to the control and made up 717.5 g. It was established that use of Nutrimin premix as part of compound feed led to a decrease in consumption of feed for 1 kg of weight gain by 0.39 ECO, or by 10.5%. Conclusions. The use of Nutrimin premix as part of compound feed for weaning pigs contributes to increasing average daily gains and reducing feed costs per unit of production.
Designs, Designing, Designers, and Design Science Revisited
Authors: Ruohonen Jukka
Published: August 2024

Design science has gained popularity in information systems. In essence, it is about designing, building, and evaluating artifacts. Despite the popularity and a lot of associated research, plenty of problems still remain. To this end, this position paper presents a critical reflection of the design science field in information systems. Building on existing research and other reflections, including literature reviews, seven important and relevant arguments are raised. Among these are the ontological and epistemological foundations; by argument, designs should be separated from artifacts, and from designing and designers. In addition, the arguments include observations and critical points about terminology, longitudinal research and the evolution of designs and artifacts, evaluation of artifacts and designs, ethics, and education. With these critical arguments, the paper contributes to the disciplinary discussion in the design science field and information systems in general by elaborating problems that need attention. By fixing the problems in future research, the design science field can advance further.

Published: August 2024

Global warming is a phenomenon that has widespread effects, particularly on environmental aspects. Globally, the impact of global warming is evident in the rising temperatures of the Earth. In April 2023, much of South Asia experienced a heatwave with temperatures exceeding 40°C. In Indonesia, the daily maximum temperature recorded reached 37.2°C in South Tangerang City. Global warming is caused by the increasing concentration of greenhouse gases in the Earth's atmosphere. This study proposes a model for predicting air temperature by considering the influence of pollutant levels and daily climate data in South Tangerang City. The prediction modeling in this study uses the Multiple Linear Regression algorithm with an 80% training data and 20% testing data split. Out of 8 trials, the sixth model is the best with a k value of 8 and features including RH_avg, RR, ss, ddd_car, ff_avg, no2, o3, and pm10. The evaluation results of the sixth model yielded an R² value of 0.72749, MAE of 0.55593, MSE of 0.50078, and MAPE of 1.99806%.

Logistic equation with long delay feedback
Authors: Kashchenko S. A.
Published: August 2024

We study the local dynamics of a logistic equation with delay and with additional feedback containing a large delay. Critical cases in the problem of stability of the zero equilibrium state are identified and it is shown that they have infinite dimension. Well-known methods for studying local dynamics, based on the application of the theory of invariant integral manifolds and normal forms, are not applicable here. Methods of infinite-dimensional normalization proposed by the author are used and developed. As the main results, special nonlinear boundary value problems of parabolic type are constructed, which play the role of normal forms. They determine the main terms of the asymptotic expansions of solutions to the original equation. They are called quasinormal forms.

Published: August 2024

The results of comparative assessment of biochemical composition of cherry fruits of varieties of local selection and introduced in the conditions of the foothill province of Dagestan, contributing to the identification of priority varieties according to selection and technological characteristics and biochemical composition, are presented. The objects of research (conducted in 2015–2023) were the fruits of ten varieties of cherries: Shaten Morel, Padus Maaki, Hejman Konservnyj, Basler Adler, Verderishche Dlakenkirshche, Bella, Annaya, Shpanka Dagestanskaya, Shurinka and Podbelskaya. The nutrient profile of the fruit was evaluated by the mass concentration of sugars, acids, vitamin C, pectin and polyphenol compounds using conventional biochemical analysis methods. According to the data obtained, the varieties Basler Adler, Shaten Morel, Hejman Konservnyj, Annaya, Shpanka Dagestanskaya and Shurinka were characterized by a high content of soluble solids (RSV) – 15.8…17.4 % and sugars – 10.1…12.2 % than the reference variety Podbelskaya – 8.9 % sugars and 15.1 % RSV. The best in terms of the stock of pectin substances (0.75…0.90 %) were the fruits of the introduced varieties of cherries Padus Maaki, Basler Adler, Shaten Morel, and among the varieties of local selection were the leaders – Shpanka Dagestanskaya and Annaya. Varieties Basler Adler, Shaten Morel, Hejman Konservnyj, Shpanka Dagestanskaya and Shurinka distinguished themselves by the greatest ability to accumulate vitamin C (9.0…11.0 mg/100g), P-active substances (126.1…151.7 mg/100g) and anthocyanins (187.2…217.8 mg/100g), compared to Podbelskaya variety, in which the mass concentrations of these substances were 8.2, 109.6 and 176.0 mg/100g, respectively. The results of the study of the nutrient profile of cherry assortment made it possible to determine promising varieties (Hejman Konservnyj, Basler Adler, Shaten Morel, Shpanka Dagestanskaya and Shurinka) to optimize the industrial cherry assortment in Dagestan, use in breeding and for the production of new types of healthy foods.
Valuation of South China tiger conservation in Wangcheng Park, China: A discrete choice experiment accounting for attribute nonattendance
Authors: Li Yuanyuan , Mohamad Wan Norhidayah W. , Samdin Zaiton
Published: August 2024

The South China tiger is endemic to China and has been evaluated as critically endangered (possible extinct in the wild) by IUCN since 2008, which resulted in distributing them zoos in China to conserve its species before finding a suitable area in the wild and bringing them back to the roar. Economic valuations of endangered species can help policymakers develop more efficient conservation strategies. Discrete choice experiment is becoming more appropriate, allowing the valuation of specific attributes of environmental goods and services. However, ignoring the attribute nonattendance issue in the DCE analysis yields biased estimates and erroneous potential recommendations. In this study, multinomial logit and mixed logit models are estimated to explore visitors' preferences and the implications of attribute nonattendance issues by using supplementary questions. The results indicate that the number of SCT is the most preferred attribute, followed by size of the natural habitat, frequency of the conservation campaigns, and level of the conservation institutions. Moreover, the results also show that accounting for attribute nonattendance does not change the relative ranking order of visitors' preferences in both multinomial and mixed logit models, while yielding higher WTP estimates in both models. These results shed more light on the importance of attribute nonattendance in future DCE analyses
An investigation into the difficulties faced by high school students in learning homeostasis
Authors: Rachidi Fatine , Aidoun Anouar , Zerhane Rajae , Janati- Idrissi Rachid
Published: August 2024

Homeostasis is a core concept not only for specialized physiologists but also for science students. Numerous studies around the globe suggest that homeostasis is a central and yet very challenging concept to grasp by students. However, to date, the existing research on this issue is remarkably limited –if not absent- in many Arab and African countries, including Morocco. In this vein, the present study sought to answer a central question: Does the comprehension of homeostasis present the same level of difficulty for high school students in Morocco asthe literature in other educational settings reveal? To answer this question, a mixed methods approach was employed, combining both qualitative and quantitative data to provide a comprehensive overview on the issue. A random sample of 42 high school students participated in a structured interview, While 107 high school Sciences teachers participated in an online survey. Both thematic analysis and SPSS were used to treat the data collected. The results indicate a notable consensus among students and teachers regarding the challenges in grasping the concept of homeostasis. While most of students struggle to provide accurate answers to basic low and high orders questions on homeostasis during the interview, there was a strong consensus among teachers that the challenges faced by students fall into major categories including the complexity of the concept, the insufficient amount of time allotted for teaching the "Endocrine and Neural Signaling" unit in high school curriculum, and students' lack of prior knowledge to name but a few. The study concludes with a set of practical recommendations to address these challenges in the Moroccan context and beyond.
A new multiple-chaos image encryption algorithm based on block compressive sensing, swin transformer, and wild horse optimization
Authors: Kadhim Qutaiba , Al-Jawher Waleed Ameen Mahmoud
Published: August 2024

Due to remote working and learning, the quantity of images communicated on public networks has significantly increased in recent years. The need for image encryption algorithms with appropriate capacity and high efficiency is growing due to the limitations of traditional image encryption algorithms. This paper proposes a multiple-chaos algorithm based on block compressive sensing (BCS), swin transformer (ST), and Wild Horse Optimization (WHO) for encryption. First, the Discreet Wavelet Transform (DWT) will be applied to the image. Then, the image confusion will be performed using the FAN Transform. Second, The image will be divided into 16 blocks each block is 64×64 pixels, and each block is compressed using the Hadamard Matrix. All blocks are masked together and quantified in the contents of the image. Next, a diffusion process will be applied to image pixels through the chaos numbers, which were generated using the Swin Transformer (ST). As well as The Wild Horse optimization (WHO) was used as a scrambling tool to obtain the encrypted image. Finally, block compressive sensing (BCS) will be applied to increase the processing speed and security. From testing the proposed algorithm it was shown that it is efficient and robust enough to fend off numerous assaults, as shown by actual trials. The average information entropy in simulation trials was 7.9749, the average for NPCR was 99.5453%, the PSNR average was 34.0248 and the average for UACI was 33.4224%. The data indicates that the method is robust enough to withstand multiple attacks. Higher values of the average measurement confirm the security of the encryption algorithm.
The matter of public expenditure on different levels of education for economic growth in EU countries
Authors: Kamberaj Altina , Kamberaj Naim , Bexheti Abdylmenaf
Published: August 2024

This paper aims to investigate the effect of public government expenditures on primary, secondary, and higher education on economic growth in 22 European Union (EU) countries for a period of 15 years. Public expenditure on primary and higher education is seen to have a positive or negative impact in countries included in both models, while the impact of public expenditure on secondary education does not appear to be significant in the first model. Hence, in the second model, it is considered half-important. Significant differences were also found between countries with higher GDPs and those with lower GDPs. Countries with higher government expenditures on education seem to matter more, thus leading to better results from the respective clusters. Conversely, levels of education that involve greater government expenditure are less important, while levels that involve less government expenditure are more important.

Published: August 2024

Diabetes Macular edema (DME) is a coexisting condition that occurs in conjunction with Diabetic Retinopathy, regardless of its severity. It has the potential to cause significant vision impairment ranging from mild to severe. If not addressed, it can also impact the eye's structure and visual results. The objective of this research to evaluate and compare the efficacy of two therapies, Bevacizumab and Ranibizumab, in managing diabetic retinopathy accompanied with macular edema. The goal was to determine the most efficient course of treatment. The ophthalmic evaluation included measurements of visual acuity, contrast sensitivity, and central fovea thickness using standardized protocols. The study groups received Bevacizumab and Ranibizumab. The mean changes in BCVA, CS, and CFT were analyzed to determine any differences between the two groups over 4 weeks. The study comprised a sample of 30 individuals, corresponding to a total of 60 eyes, with an average age of 53.9±9.7 years. The average central foveal thickness (CFT) decreased significantly in group 2 (ΔCFT= 157±114.22 µm) after 4 weeks, but there was no significant change in group 1 (ΔCFT= 144.3±93.7µm; p=0.787). The group 2 participants had a significant improvement in BCVA and CS after 4 weeks, with a change in BCVA of 0.39±0.27 compared to 0.6±0.41 LogMAR (p<0.001). However, the statistical analysis showed that the impact of CS was not significant (p=0.311). Bevacizumab and ranibizumab had similar effects with a decrease in foveal thickness following a single dose. Anti-VEGF resulted in a decrease in foveal thickness within the same time period, proving to be equally effective. When it comes to short-term effects on structural and visual functions, bevacizumab and ranibizumab appear to be interchangeable.

Published: August 2024

The high market demand for nilem fish must be balanced with good hatcheries. One of the success factors of hatcheries is the hatchability of fish eggs. Egg hatchability is the percentage of eggs that hatch after a certain time. The hatchability of fish eggs is certainly influenced by several factors, one of which is pH which affects the chorionase enzyme in eggs. The purpose of this study was to determine the effect of different pH in the media on the hatching of nilem fish eggs. The research method used is an experimental method with a complete randomized design (RAL). The mainmain parameters used in this study are embryo development, hatching rate (HR), larval abnormality, and larval survivale (SR) and the supporting parameters used in this study are temperature and DO. The results showed that pH treatment had a significantly different effect on the hatching of nilem fish eggs. The best result of HR in nilem fish was 95% at pH (9) and the lowest result of HR in nilem fish was 15% pH (11). The hatchability relationship of eggs given different treatments formed a quadratic equation. The results showed that pH treatment affects the SR value. The best SR result of nilemfish larvae was 93% at pH (9) and the lowest SR result was 0% at pH (11). The survivale rate relationship of eggs given different treatments formed a quadratic equation.

Balita adalah kelompok yang rentan masalah gizi salah satunya adalah stunting karena pada usia tersebut mereka mulai mengenal dan mengikuti pola makan orang dewasa. Stunting disebabkan oleh faktor yang sangat komplek yaitu ketahanan pangan, pengetahuan ibu, pola asuh, pelayanan kesehatan, pengetahuan keluarga, berat badan lahir, penyakit infeksi, dan asi ekslusif. Penelitian ini bertujuan untuk mengetahui hubungan antara pemberian makanan, pemberian asi esklusif dan bblr dengan kejadian stunting pada balita di Wilayah Kerja Puskesmas Pugaan Kabupaten Tabalong. Metode penelitian ini menggunakan observasional analitik dengan rancangan kasus kontrol. Populasi adalah balita usia 24-59 bulan dengan sampel penelitian 82 orang yang diambil menggunakan dengan teknik purposive sampling. Variabel penelitian ini yaitu pemberian makanan, pemberian asi esklusif, bblr dan kejadian stunting. Pengambilan data dengan cara kuesioner dan wawancara serta analisis data menggunakan uji Chi-Square. Hasil penelitian ini menunjukan 95,2% pemberian makanan kurang tepat pada balita stunting dan 2,4% pada balita tidak stunting. Terdapat 41,5% ASI Ekslusif pada balita stunting dan 68,3% pada balita tidak stunting. Terdapat 24,4% balita yang mengalami BBLR pada balita stunting dan 14,6% pada balita tidak stunting. Ada hubungan pemberian makanan, dan pemberian ASI Ekslusif dengan kejadian stunting. Tidak ada hubungan berat badan lahir dengan kejadian stunting. Diharapkan kepada ibu balita sering mengikuti penyuluhan-penyuluhan di posyandu dan di puskesmas, ataupun mencari informasi tentang stunting di media sosial.
Growth of holomorphic curves with radially distributed hypersurfaces and uniqueness of holomorphic curves in angular domain
Authors: Van Thin Nguyen
Published: August 2024

In this paper, we establish the results about spread relation to holomorphic curve intersecting hypersurfaces. Using the spread relation for holomorphic curve and Second Main Theorem, we prove some results for uniqueness problem of holomorphic curve by inverse image of hypersurfaces on angular domain. In my knowledge, it is the first time that uniqueness problem for holomorphic curves on angular domain into projective space intersecting with hypersurfaces is studied. Furthermore, we also study the growth of holomorphic curves with radially distributed hypersurfaces.
Impaired Dynamics of Positional and Contextual Neural Coding in an Alzheimer’s Disease Rat Model

Background:

The hippocampal representation of space, formed by the collective activity of populations of place cells, is considered as a substrate of spatial memory. Alzheimer’s disease (AD), a widespread severe neurodegenerative condition of multifactorial origin, typically exhibits spatial memory deficits among its early clinical signs before more severe cognitive impacts develop.

Objective:

To investigate mechanisms of spatial memory impairment in a double transgenic rat model of AD.

Methods:

In this study, we utilized 9–12-month-old double-transgenic TgF344-AD rats and age-matched controls to analyze the spatial coding properties of CA1 place cells. We characterized the spatial memory representation, assessed cells’ spatial information content and direction-specific activity, and compared their population coding in familiar and novel conditions.

Results:

Our findings revealed that TgF344-AD animals exhibited lower precision in coding, as evidenced by reduced spatial information and larger receptive zones. This impairment was evident in maps representing novel environments. While controls instantly encoded directional context during their initial exposure to a novel environment, transgenics struggled to incorporate this information into the newly developed hippocampal spatial representation. This resulted in impairment in orthogonalization of stored activity patterns, an important feature directly related to episodic memory encoding capacity.

Conclusions:

Overall, the results shed light on the nature of impairment at both the single-cell and population levels in the transgenic AD model. In addition to the observed spatial coding inaccuracy, the findings reveal a significantly impaired ability to adaptively modify and refine newly stored hippocampal memory patterns.

Background:

Mild cognitive impairment (MCI) is a heterogeneous condition that can precede various forms of dementia, including Alzheimer’s disease (AD). Identifying MCI subjects who are at high risk of progressing to AD is of major clinical relevance. Enlarged perivascular spaces (EPVS) on MRI are linked to cognitive decline, but their predictive value for MCI to AD progression is unclear.

Objective:

This study aims to assess the predictive value of EPVS for MCI to AD progression and develop a predictive model combining EPVS grading with clinical and laboratory data to estimate conversion risk.

Methods:

We analyzed 358 patients with MCI from the ADNI database, consisting of 177 MCI-AD converters and 181 non-converters. The data collected included demographic information, imaging data (including perivascular spaces grade), clinical assessments, and laboratory test results. Variable selection was conducted using the Least Absolute Shrinkage and Selection Operator (LASSO) method, followed by logistic regression to develop predictive model.

Results:

In the univariate logistic regression analysis, both moderate (OR = 5.54, 95% CI [3.04–10.18]) and severe (OR = 25.04, 95% CI [10.07–62.23]) enlargements of the centrum semiovale perivascular space (CSO-PVS) were found to be strong predictors of disease progression. LASSO analyses yielded 12 variables, refined to six in the final model: APOE4 genotype, ADAS11 score, CSO-PVS grade, and volumes of entorhinal, fusiform, and midtemporal regions, with an AUC of 0.956 in the training and 0.912 in the validation cohort.

Conclusions:

Our predictive model, emphasizing EPVS assessment, provides clinicians with a practical tool for early detection and management of AD risk in MCI patients.
Never Mind the Codes of Conduct. DARE You to Tackle Ethics in Software Development for eHealth
Authors: Krumme Julia , Wienands Linda , Teynor Alexandra
Published: August 2024

Currently, there are no adequate methods for dealing with changes in the healthcare system brought about by electronic health applications (eHealth) or the associated ethical implications in practice. This can be attributed to the lack of comprehensive interdisciplinary approaches that could support teams in integrating ethical considerations into the agile software development process. To close this gap, the DARE approach has been developed and tested in interdisciplinary collaborative research. The DARE method is a modular system designed to improve the development of ethically sound software in a deliberative, agile, and responsive manner.
