Berdasarkan instruksi dari Badan Akreditasi Nasional Pendidikan Anak Usia Dini (BAN-PAUD), salah alat yang harus disediakan oleh pihak sekolah adalah Buku Penghubung, sebagai media untuk monitoring dan pelaporan tumbuh kembang siswa kepada orang tuanya. Sekolah Alam Gaharu (SAG) Bandung telah menggunakan Buku Penghubung, namun sistemnya masih tergolong konvensional. Pada sistem konvensional ini ditemukan permasalahan-permasalahan yang mengakibatkan ketidakselarasan antara wali murid dan guru/fasilitator kelas dalam hal monitoring tumbuh kembang anak, seperti: buku yang rentan rusak atau hilang, kurang privasi, tidak real-time dan tidak dapat mengakomodasi file foto/video kegiatan. Dengan kemajuan teknologi pada era sekarang, memungkinkan dilakukan transformasi buku penghubung berbasis kertas menjadi bentuk aplikasi digital berbasis website maupun Android/iOS. Untuk itu, pada kegiatan pengabdian masyarakat ini dikenalkan sebuah aplikasi Buku Penghubung Digital bernama Kids Note. Pelatihan diberikan kepada 50 peserta yang terdiri dari orang tua/wali murid dan guru/fasilitator di Sekolah Alam Gaharu. Berdasarkan survei yang dibagikan pasca kegiatan, didapatkan hasil bahwa 84% peserta memahami cara penggunaan aplikasi Kids Note dan 92% diantaranya menyatakan aplikasi Kids Note mampu mengakomodasi kebutuhan monitoring dan pelaporan tumbuh kembang anak di SAG.

Authors: Kotliar Elena Romanovna , Puntus Ekaterina Yur'evna
Published: March 2023

The subject of the study is the cultural code "Bestiary", which combines symbolic images of animals and chimeras in the Jewish pictorial semiosis. The object of the study is traditional symbolism in Jewish pictorial practice. The article uses the methods of semiotic analysis in deciphering the meanings of the elements of the traditional pictorial Jewish semiosis, the method of analyzing previous studies, the method of synthesis in substantiating sets of signs. In their work, the authors consider the following aspects of the topic: the main codes of the Jewish pictorial semiosis are highlighted, their morphology, interrelationships, key meanings and the main code are substantiated. The Bestiary code, its features, etymology and reading are considered in detail. The main conclusions of the study are: 1. Based on the study of Jewish traditional culture, five main codes of pictorial semiosis in Judaism were identified, uniting a group of symbols: skewomorphic (subject), phytomorphic (plant), zoomorphic (animal), numeric. The primary source of all codes and the unifying code is the Sefer code (Book). The interactions between the codes are revealed, the key meanings are the symbolism of Creation, Paradise, Torah persons and Messianic aspirations. The semantic center of the codes – the Torah and Aron Hakodesh, as a repository of the Torah, is revealed. 2. The Bestiary code considered in detail represents the symbolism of traditional images of animals and chimeras, which is connected with the prohibition in Judaism on the image of a person. Images of representatives of the world of animals, birds, fish, as well as mythical creatures in the Jewish reading convey the meanings of human virtues and negative qualities, and also indicate Messianic hopes laid down in the Torah and especially in the Midrash Talmud.The scientific novelty of the study consists in the fact that for the first time a culturological analysis was carried out and the interrelationships of cultural codes in the Jewish pictorial semiosis were structured, with an emphasis on the Bestiary code.

Abstract
One of the factors that affect the quality of cocoa beans is post-harvest handling such as the fermentation process. Fermentation plays an important role in determining the final quality of dried cocoa beans. Chocolate flavors can be produced from microbial fermentation from high-quality cocoa bean raw materials by utilizing microbes. This study aims to calculate the number of microbes at the beginning and end of the cocoa bean fermentation process, observing the pH value, temperature, and color of cocoa beans. The treatment carried out is a fermentation variation consisting of: (1) natural fermentation or without the addition of microorganisms; (2) controlled fermentation with the addition of microorganisms consisting of Saccharomyces cerevisiae, Lactic Acid Bacteria simultaneously added at the beginning of fermentation. The addition of microorganisms is 106 CFU / 1kg of cocoa beans each. Fermentation is carried out in a fermentation box with a capacity of 1 kg of fresh cocoa, at room temperature (33-35oC), for 4 days. The analysis carried out includes calculating the number of microbes at the beginning and end of fermentation, measuring pH, and organoleptic observations of the color of fermented cocoa beans. The results of the experiment can be concluded that there is an increase in the addition of mixed inoculum (Saccharomyces cerevisiae and Lactobacillus lactis) affecting the influence of chemical changes of the substrate during fermentation; the temperature value in cocoa fermentation ranges from 30 – 32 oC, the pH value in cocoa fermentation does not have a significant increase; and the color of cocoa beans from mixed inoculum fermentation is close to good with a dominant brown color against purple

Published: March 2023

The objective of this research was to study the nutritional status of children before receiving biscuits, the biscuit supplementation regularity, the adequacy of the biscuits received and consumed by the children according to recommendations, and the relationship between supplementary biscuits consumption and nutritional status. Using a cross-sectional study design, the study was conducted in 2017 involving 586 children in three regions (11 provinces) in Indonesia. A chi-square test was performed to see the relationship between supplementary biscuits consumption and nutritional status. The most common nutritional problems were stunting-wasting (34.1%), stunting (32.6%), and wasting (23.9%). The nutritional problems occurred most often in the eastern region (96.4%), followed by the central region (95.5%) and the western (87.1%). Within three months, 66–78% of respondents received supplementary biscuits regularly, but only 10–29% received the supplementary biscuits as recommended in the same period. Within the three months’ period, from respondents that received the supplementary biscuits as recommended, the region in which children consumed the biscuits according to the recommendations the most was the eastern region (45.2%), followed by the western (23.3%) and central regions (5.3%). Children who consumed biscuits as recommended in the three months’ period had a 2.9 times possibility of having a normal nutritional status (categorized based on the weight-for-age index) (p-value=0.049).

Published: March 2023

This cross-sectional study aimed to examine breastfeeding trends and factors in Indonesia using Demographic Health Survey (DHS) data from 2007 to 2017. The research data were obtained from three Indonesia Demographic Health Surveys. The data covered households and women aged 15‒49 years old, including 40,701 households and 32,895 women in 2007; 43,852 households and 45,607 women in 2012; and 47,963 households and 49,627 women in 2017. Descriptive statistics was deployed to analyze the sociodemographic factors of the respondents. A questionnaire was employed to obtain data on the mothers' age, residence, education, economic status, mother working, marital status, literacy, place of delivery, first Antenatal Care (ANC) place, child size at birth, and gender of the child. Multinomial logistic regression analysis was used to analyze factors related to breastfeeding and how big the impact is. The findings indicate that the trend of breastfeeding in Indonesia significantly decreased based on the characteristics of mothers and children. The rates of breastfeeding (exclusive breastfeeding infants aged 0‒5 months who received only breast milk) among mothers living in urban areas decreased significantly from 41.6% in 2012 to 38.4% in 2017. In 2017, children with normal birth weight (OR=0.87, 95% CI:0.53‒1.45), boys (OR=1.01, 95% CI:0.92‒1.10), and non-illiterate mothers (OR=0.50, 95% CI:0.46‒0.55) had higher odds of breastfeeding compared to children with small birth weight, girls, and illiterate mothers. Factors associated with breastfeeding also change every year. In 2012, breastfeeding was related to marital status and delivery, but in 2017 it was not associated with those factors. Factors related to breastfeeding in Indonesia are age, residence, education, weight index, size of child at birth, mother’s occupation, marital status, literacy, place of delivery, and first ANC place. These results are important for developing policies to improve maternal and child health in Indonesia by increasing education and mother training for early initiation of breastfeeding.

Published: March 2023

This study aimed to determine the awareness, knowledge, and practices regarding food labels and factors that influence their use; a cross-sectional study was conducted among 200 Malaysian adolescents aged 10 to 19. Participants completed an online Food Label Use Questionnaire (FLUQ) that included demographic, nutrition knowledge, label use, and factors affecting label use. SPSS version 28.0 was used for data analysis. The results showed that 93% of adolescents correctly identified the consequences of over-consuming calories. Still, only 84.5% performed well on the nutrition use task, struggling to interpret calorie and carbohydrate amounts in certain foods. The main reasons for not using food labels were time constraints (45.5%), unattractive or confusing labels (36%), absence of labels on certain foods (33%), lack of health concerns (32%), and insufficient knowledge (27%). However, 90.5% of adolescents were concerned about product expiration dates and often read this information. Taste and price were the main reasons for referring to food labels, while time constraints were the main barrier to their use. In conclusion, practicing reading food labels can guide adolescents in making informed decisions about their food choices and portion intake. Awareness campaigns can aid in promoting healthy habits and empowering adolescents to make the right choices for their health.

Religion, Armed Conflict and the Quest for "Secular" - Mapping Martyrdom in Kashmir
Authors: Yalçın Resul , Gul Umair
Published: March 2023

Religion is bivalent. It can be argued that religion is an instrument of peace and equivocally the role of religion in conflicts can be voiced as well. Religion can be a motivation to perpetuate violence; it can also be a background to conflict or it can be the means and end for parties involved in the conflict. Armed conflict has been a key feature of contemporary world politics, and its relation with religion would be interesting to probe into. Kashmir has been a festering political problem with little global attention. Intangible political positions have led to shame and humiliation. Kashmir has to resort to ‘scapegoating’ in the form of a ‘body of a militant’ as a sacrifice. The failure of the secular world to deliver on its secular promises in the form of the right to self-determination is increasingly turning the local populace to transcendental means to achieve the secular. This paper will try to contextualize the quest for “secular” while examining the construction of Muslim identity, the institution of martyrdom, and its societal basis in Kashmir.
JAK inhibitors in dermatology

Published: March 2023

The four Janus Kinase (JAK) proteins and seven signal transducer and activator of transcription (STAT) factors mediate the intracellular signaling pathway of cytokine receptors, which are described in the pathogenesis of many autoimmune, allergic, and inflammatory dermatoses. The development of targeted small-molecule therapies like JAK inhibitors has enabled a paradigm shift in the treatment of various cutaneous disorders. JAK inhibitors are effective in the treatment of atopic dermatitis, vitiligo, alopecia areata, psoriasis, lupus erythematosus, dermatomyositis, mastocytosis, etc. Various blood parameters include complete blood count, liver, and renal function, the viral marker to be checked and tuberculosis to be ruled out before starting the therapy. There is a risk of acquiring serious infections such as upper respiratory tract infections, urinary tract infections, reactivation of latent tuberculosis, opportunistic infections, hepatitis B virus reactivation, and alteration of various blood parameters; so regular monitoring is required. The use of JAK inhibitors will open a new horizon by reducing the burden of systemic steroids and other non-specific immunosuppressants in the treatment of immune-mediated inflammatory dermatoses.
Ligelizumab: A novel molecule in the management of chronic spontaneous urticaria
Authors: Datta Shreya , Chakraborty Disha , De Abhishek
Published: March 2023

The next-generation high affinity monoclonal immunoglobulin E (IgE) inhibitor Ligelizumab is being tested in clinical studies to treat chronic spontaneous urticaria (CSU). In 2020, the US Food and Drug Administration (FDA) designated Ligelizumab (QGE031) as a breakthrough therapy for patients with chronic idiopathic urticaria; however, FDA clearance has not yet been granted, despite the phase 3 trial’s completion. Recent clinical investigations have shown that it has a considerable affinity for the high-affinity IgE receptor (FcRI) on the surface of immune cells, which is quite beneficial in the management of the distressing symptoms of CSU. Studies have been done comparing Ligelizumab to Omalizumab, the current standard of care for treating CSU that is refractory. While omalizumab is more effective than Ligelizumab at inhibiting IgE: CD23 interactions, Ligelizumab exhibits stronger inhibition of IgE binding to FcRI, basophil activation, IgE synthesis by B cells, and passive systemic anaphylaxis. To learn about this molecule’s extended characteristics, long-term efficacy and safety, and potential uses in other dermatological disorders, more clinical data is needed.

Machine Learning for Elastic Properties of Materials: A predictive benchmarking study in a domain-segmented feature Space
Authors: Banik Suvo , Balasubramanian Karthik , Manna Sukriti , Derrible Sybil , Sankaranarayananan Subramanian
Published: March 2023

Insights into the unique characteristics across different classes of materials are crucial for Machine Learning (ML) tools and reveal the physics behind the studied process. Traditional predictive modeling of elastic properties of materials is limited to only a few classes of materials and a small set of ML tools despite the broad applications of these materials. While in recent years, Graph neural networks (GNNs) have outshined traditional ML models in terms of predictability, their intensive data requirement and lack of interpretability may limit practical applicability. In this work, we developed a domain-segmented feature space using a diverse set of material attributes and performed a predictive analysis of elastic properties of materials using state-of-the-art ML tools. By deducing the model-independent overall ranking of the features based on feature importance learned by each model, the knowledge is then transferred to GNNs. The findings indicate a saturation limit in the predictability of traditional ML models, but the transfer of task-specific feature importance knowledge to the GNNs can enhance their performance by reducing their data requirement while retaining considerable accuracy.
The lowest nπ* states of heteroaromatics: When and in what way are they aromatic or antiaromatic?
Authors: Proos Vedin Nathalie , Escayola Sílvia , Radenković Slavko , Solà Miquel , Ottosson Henrik
Published: March 2023

Heteroaromatic molecules are ubiquitous and found in many areas of chemistry, ranging from biochemistry to organic electronics. Herein we analyse the nπ* excited states of (4n+2)π-electron heteroaromatic compounds that have in-plane lone-pair orbitals, using both qualitative theory and quantum chemical computations. The starting point of our analysis is Mandado’s 2n+1 rule for aromaticity of separate spins. After excitation of an electron from n to π* a (4n+2)π-electron species will have 2n+2 π(alpha)-electrons and 2n+1 π(beta)-electrons (or vice versa), and thus would be π(alpha)-antiaromatic and π(beta)-aromatic. We ask, does this lead to a nonaromatic nπ* state? We show that the situation is complex as the antiaromatic π(alpha)- and the aromatic π(beta)-components often do not cancel, leading to residuals which either lean towards aromaticity or antiaromaticity. Focus is placed on the vertically excited nπ* states with triplet multiplicity as they are most readily analysed, yet we also explore singlet nπ* states. Pyrazine and the phenyl anion are examples of molecules with residuals in their nπ* states which are markedly aromatic. We seek and provide qualitative explanations as to which compounds have nπ* states with residuals which are aromatic in character, and which ones are antiaromatic. Our results show that if the π(beta)-electron population becomes more uniformly distributed in the excitation, the system will have an aromatic residual and vice versa. For isomeric species, the isomer with the most aromatic residual in triplet nπ* is often of lowest relative energy in this state. Finally, we connect our findings to the recently observed adaptive aromaticity phenomenon, especially found in some metallaaromatics, and show that it can be understood with the general theoretical framework described herein.

Published: March 2023

The developments made towards increasingly photoactive copper(I) complexes has led to their use in many applications involving light, in particular light emission or photocatalytic activities. Herein, we describe an unprecedented in-depth study of the photophysical properties of two of the most used copper(I) photosensitizers, [Cu(bcp)(Xantphos)]+ and [Cu(bcp)(DPEphos)]+ (bcp = bathocuproine, Xantphos = 4,5-Bis(diphenylphosphino)-9,9-dimethylxanthene, DPEphos = Bis[(2-diphenylphosphino)phenyl]ether). This study combines traditional spectroscopic techniques with state-of-the-art femtosecond time-resolved transient absorption and fluorescence up-conversion spectroscopy and is further supported by quantum-chemical calculations. This combined analysis hints at the presence of a low-lying ligand-centered dark triplet state which plays a crucial role by acting as a reservoir for the excited hetereloptic copper(I) complexes.

Amination of aryl chlorides by metallaphotocatalysis is highly desired but remained practically challenging. Meanwhile, relying on soluble noble-metal photocatalysts suffers from resource scarcity and structural instability which limit their practical application. Here in, a highly crystalline acetylene-based hydrazone-linked BTH-THFEB COF is reported that enable metallaphotocatalytic amination of aryl chlorides. The non-planar effect of hydrazone linkage and weak interlayer attraction of acetylene bond were minimized by intralayer hydrogen-bonding. As a result, the COF showed not only an improved crystallinity and porosity, but also enhanced optical and electronic properties compared to a COF analogue without hydrogen-bonding. Notably, dual BTH-THFEB/Ni system afforded C─N coupling products from broad aryl chloride substrates in excellent yields (up to 99%) and good functional tolerance. Furthermore, BTH-THFEB is recoverable and reusable for five times photocatalysis cycles. This report demonstrates simple approach to tune the structure-activity relationship in COFs at molecular level.
Investigation of Performance of Nano Silica Cement Additive on Sulphate Attack In Geothermal Wells
Authors: Luswata G.N. , Onyancha D. , Thuo J. N.
Published: March 2023

Purpose: This research was intended to evaluate Nano silica as an additive to improve the sulphate resistance of cement used in geothermal wells.

Design/ Methodology/ Approach: Sulphate resistance was determined by measuring the longitudinal change in cement cube specimens that were cured in sodium sulphate solution for 21 days. Cube specimens with varied concentrations of Nano silica (0%, 0.3%, 0.6%, 0.9% and 1.2%) were used in the study. Five separate solutions were maintained at 23℃, 40℃, 65℃, 70℃ and 80℃ for 21 days. Final length measurements were taken and compared as a percentage of initial length measurements.

Findings: Beyond 65℃, the sulphate resistance of cement improved for each percentage concentration of Nano silica replacement. Control specimens with 0% Nano silica had the most inferior performance at all temperatures. Higher concentrations of 1.2% and 0.6% Nano silica replacement gave the most resistance between 23℃ and 65℃. A lower concentration of 0.3% proved more suitable between 65℃ and 80℃.

Research limitation: The results of the experiment indicate performance in low-temperature geothermal wells.

Practical implications: The application of this additive can improve the durability and strength of the cement, reducing the potential for degradation due to exposure to sulphates. This can lead to a longer lifespan of the geothermal well, reducing maintenance costs and increasing its overall efficiency.

Social implications: Improved cement designs that create longer-lasting cement sheaths can be developed from this research, thereby fostering geothermal energy development. The option to replace certain volumes of cement with Nano silica contributes to a reduction of the carbon footprint by minimising the demand for, and therefore the production of cement.  

Originality/ Value/ Novelty: Previous research that tested cement at high temperatures analysed mechanical resistance. This research examined the sulphate resistance of cement at high temperatures.

Published: March 2023

Fog computing systems, by design, have a high degree of redundancy in terms of computing and storage resources. To make the most of this redundancy, coding techniques can be used to transform the data being transferred and processed. Two specific coding ideas that have been proposed for use in fog computing are minimum bandwidth codes and minimum latency codes. These codes have the potential to significantly reduce data transfer capacity utilization and computation inactivity. Minimum bandwidth codes focus on reducing the amount of data that needs to be transferred, while minimum latency codes focus on reducing the amount of time it takes for data to be processed. These two coding methods can be combined in a linked coding structure that allows for a trade-off between computation inactivity and communication load, leading to improved system performance. Fog computing has been proposed as a solution to meet the management requirements of the growing Internet of Things (IoT) and smart networks. This research breaks down the capabilities and challenges of fog computing in smart networks, presents the state-of-theart in the field, defines a fog computing-based smart grid, and provides a use case scenario for the proposed model.

Facial Expression Recognition (FER) has grown in popularity as a result of the recent advancement and use of humancomputer interface technologies. Because the images can vary in brightness, backdrop, position, etc. it is challenging for current machine learning and deep learning models to identify facial expression. If the database is small, it doesn't operate well. Feature extraction is crucial for FER, and if the derived characteristics can be separated, even a straightforward approach can help tremendously. Deep learning techniques and automated feature extraction, allow some irrelevant features to conflict with important features. In this paper, we deal with limited data and simply extract useful features from images. To make data more numerous and allow for the extraction of just important facial features, we suggest innovative face cropping, rotation, and simplification procedures and advocate using the Transfer Learning technique to construct DCNN for building a very accurate FER system. By replacing the dense top layer(s) with FER, a pretrained DCNN model is adopted, and the model is then modified with facial expression data. The training of the dense layer(s) is followed by adjusting each of the pre-trained DCNN blocks in turn. This new pipeline technique has gradually increased the accuracy of FER to a higher degree. On the CK+ and JAFFE datasets, experiments were run to assess the suggested methodology. For 7-class studies on the CK+ and JAFFE databases, high average accuracy in recognition of 99.49% and 98.58% were acquired.

Analyzing digital images to reveal modifications is called image forensics. Digital images are now becoming incredibly popular due to the availability of several inexpensive image-capturing gadgets. These images are frequently altered, either unintentionally or intentionally, which causes the image to convey false information. Since digital images are frequently utilized as evidence in court proceedings, media, and for preserving visual records, approaches to detecting forgeries in these images should be designed. This paper thoroughly analyzes several image forgery detection strategies, including comparisons of the strategies, advantages, disadvantages, and experimental findings.

Published: March 2023

As English is widely accepted as a lingua franca in today's world, the importance of the language has been acknowledged globally in the present case. To rank the countries in terms of their English language proficiency, the EF Proficiency Index is prepared each year. In this study, five countries having the highest scores according to the Index (2021) were taken into account together with the English language curricula of the top five ranking EFL countries (Netherlands, Austria, Denmark, Singapore, and Norway). The English language teaching programs of these countries were analysed and compared in terms of the starting age, language assessment, and course content, adding to the comparison list a low-ranking country, Turkey. The data elicited through document analysis propounded the idea that overall, the objectives of English language curricula in these five countries have many common features and similarities. On the other hand, developing positive attitudes towards learning English is emphasised in the Turkish EFL context, and four basic language skills are treated separately in different grades. While other countries give prominence to communicative competence and communication skills together with the cognitive side of the language learning process, the affective components of the language learning process are emphasised in Turkey. Contemporary formative assessment techniques are also recommended in this continuum.

Published: March 2023

The recent advancement of digital technologies has triggered a prominent shift within the field of language education. Considering the teachers' vital roles in adopting modern instructional technologies, this study investigates in-service EFL teachers' TPACK self-efficacy levels, explores the relationship between their TPACK self-efficacy levels and their demographic features and perceptions towards Web 2.0 technologies. Employing a mixed method design, the study collected quantitative and qualitative data in two phases. The quantitative data was collected through an online survey with 227 EFL teachers from various schools. Following the first phase, seven voluntary teachers were interviewed. The findings suggested that participants had a high level of content knowledge, pedagogical content knowledge and pedagogical knowledge, but they reported a relatively low level of self-esteem when the knowledge of technology was included. Furthermore, statistically significant differences were found between the teachers' TPACK self-efficacy levels and their educational level, school type, perceived digital literacy levels and previous INSET experience on Web 2.0 technologies. A positive and high level of correlation between TPACK self-efficacy of EFL teachers and their Web 2.0 selfperceptions was also reported. Semi-structured interviews demonstrated that despite their favorable perceptions towards Web 2.0 technologies, EFL teachers do not amply utilize Web 2.0 tools in teaching mainly due to their inadequate technological and technological pedagogical knowledge.
