This research aims to provide a comprehensive understanding of the various forms of parental involvement in supporting early childhood education, while identifying the facilitating and hindering factors for the success of parental involvement programs. Findings from this study illustrate the prevailing perception among parents that still places teachers as the primary determinants of a child's success, despite the significant role parents play as the primary educators for young children. Awareness of this challenge prompted the researcher to delve into more detailed and in-depth investigations.The research results delineate diverse forms of parental involvement, encompassing the supervision of children's study time, financial contributions through donations of toys and books, participation in school meetings, involvement in social service activities, and the repair of play equipment at school. Despite the existence of organized excursions, not all schools can conduct them due to significant cost constraints.Supporting and inhibiting factors in parental involvement encompass economic aspects, time constraints, the level of parental trust in teachers, and the lack of parental involvement programs initiated by schools. These findings offer valuable insights for enhancing parental participation in early childhood education by addressing and optimizing these factors, ultimately creating a more inclusive and empowered educational environment. Keywords: forms of parental involvement; early childhood education.

Textually, Islamic inheritance law is one of the most detailed laws mentioned in the Koran, however, resolving the division of inheritance often requires repeated ijtihad by the ulama. One of the important things in the issue of inheritance is the issue of Ashabah. The results of the research concluded that the 'ashabah hadith is categorized as an authentic hadith and can be used as proof regarding the validity of the 'ashabah system in Islamic inheritance. The implementation of the 'ashabah inheritance system does not have discriminatory implications, on the contrary, it actually contains the value of distributive justice, because justice in inheritance is not always measured by the equality of designation between heirs, but is also determined by proportionality based on the size of the burden of responsibility assigned to each heir. , balance between rights and obligations and balance between what is obtained and needs and uses. This research includes a literature review, while the way it works uses descriptive qualitative methods. In this research, several Bukhori hadiths about Ashabah are included in the Ahad Gharib Muslaq Hadith category and meet the criteria for authentic hadiths that can be used as evidence. Judging from the meaning contained in this hadith, there is no discrimination in this hadith and there is no injustice towards women.

Authors: Alcantara Edwin P. , Bayot Aileen N.
Published: January 2025

Brush border membrane vesicles (BBMVs) were prepared from 4th instar larvae of Asian corn borer 0strinia furnacalis Guenee. SDS-PAGE analysis showed major protein bands with molecular weight in the range of 80 kDa to 250 kDa. Ligand blot analysis showed that biotinylated Cry1Ab o­endotoxin strongly binds to a ~250 kDa receptor protein from 0. furnacalis BBMV. Another receptor protein of ~110 kDa weakly binds to Cry1Ab o-endotoxin. At least two isoforms of the ~250 kDa receptor protein have a pH range of 5.5 to 6.5 as determined by 2D-electrophoresis. Post-translational modification of 0. furnacalis BBMV proteins was also detected as revealed by the presence of two glycosylated proteins with molecular weights of >250 kDa and 70 kDa, respectively.

Alanine scanning mutations were introduced in domain Ill 13-sheet 13 of Cry1Ab o-endotoxin. Results of bioassays showed a 5 to 7 fold reduction in insecticidal activity in Serine556Alanine, Serine557Alanine and Serine556Alanine­-Serine557Alanine mutants of Cry1Ab protein. The decrease in insecticidal activity suggests that Serine556 and Serine 557 are both important residues in the toxicity of Cry1 Ab o-endotoxin to 0. furnacalis.

With the increase of treating time in a silver salt solution the formed layer is more uniform and consists of dendrites and agglomerates. EDS results reveal that the converted samples are rich in silver and poor in copper. An examination of the XRD data of the obtained layers reveals a polycrystalline nature of the material. Various copper sulphides, silver sulphide and silver were detected in the obtained layers.
Coupling of capillary electrophoresis with reaction detection for on-line determination of radical scavenging activity
Authors: Stankevičius Mantas , Maruška Audrius
Published: January 2025

Chemical antioxidant activity assays can be classified into batch and separation-based antioxidant activity assays. Batch antioxidant activity assays measure the antioxidant compound ability to quench free radicals by a mixture of antioxidants. Batch methods are quantitative and do not provide information about individual compounds in a sample. Separation-based methods coupled with chemical antioxidant activity assays provide a possibility of the high resolution screening of individual antioxidants in the complex matrices. Capillary electrophoresis is a micro-method based on analyte separation according to the mass-to-charge ratio in a short time with high separation efficiency. Capillary electrophoresis coupled with the post-column radical scavenging reaction detection meth­od can be applied for analysis of antioxidants and evaluation of their radical scavenging activity. In this study an interface for capillary electrophoresis coupling with radical scavenging detection was created using chromatographic components which are readily available in the laboratory. Two set-ups of the interface were tested. For the first set-up a ground electrode was inserted into the reagent vessel to close the electrical circuit before the reaction detector. In this case exclusively hydrostatic pressure was used for reaction mixture delivery through the reaction coil to the reaction detector. The second set-up was created grounding the outlet vial after the reaction detector. In this case high voltage and internal pressure was applied to the separation capillary and reaction coil for the separation of analytes and delivery of the reaction mixture to the reaction detector. For optimization of the reactants mixing ratio different values of hydrostatic pressure and high voltage were tested for both set-ups. The most effective mixing of the reactants is when the flow rate in the CE separation capillary is equal to the flow rate of the reagent solution into the reaction coil. Capillary electrophoresis coupled with radical scavenging reaction detection showed good linearity (R2) (0.996 and 0.993) and repeatability (RSD 3.21 and 5.87%) for the CE detector and the reaction detector, respectively.

skutecznego kierunku strategicznej komunikacji państwa w celu kształtowania jego pozytywnego wizerunku i utrwalania marek w globalnej przestrzeni informacyjnej, jej zadań i poszerzania zestawu narzędzi w warunkach wojny
prowadzonej przez Federację Rosyjską przeciwko Ukrainie jako niezależnemu
państwu bezatomowemu. Omówiono kluczowe problemy dyplomacji publicznej, które są badane przez naukowców z różnych krajów i wdrażane
w praktyce przez dyplomatów i przedstawicieli społeczeństwa obywatelskiego.
W warunkach wojny oficjalna dyplomacja uruchomiła tradycyjne narzędzia,
w zamian znacznie rozszerzył się zestaw narzędzi i krąg podmiotów dyplomacji
publicznej. Wykorzystanie narzędzi dyplomacji publicznej jest coraz częściej
obecne w działaniach Pierwszych Dam. Dla Ukrainy mają one szczególne znaczenie po rozpoczęciu wojny na dużą skalę na Ukrainie, ponieważ poszerzają

MAPPING A “NOWHERE NATION”. THE TOXIC SPELL OF “IMPERIAL KNOWLEDGE” AND THE CHALLENGES OF DECOLONIZATION
Authors: RIABCHUK MYKOLA
Published: January 2025

Ukraine’s striking absence on mental maps of the vast majority of
Europeans, the article argues, is primarily a byproduct of Russian “imperial
knowledge”, i.e., a system of narratives developed by the empire with
the primary goal of undermining the subjectness of subjugated nations, dispossess
them from any agency and make them virtually invisible to the world and
reprehensible to themselves. That knowledge has attained international currency
as allegedly “scientific” and therefore unquestionable, and largely determined
fallacious policies of Western governments vis-à-vis both Russia and Ukraine. Its
false tenets, internalized and normalized in the West as a common wisdom, still
facilitate the global penetration of Russian anti-Ukrainian propaganda and hinders
a unified international response to Russian aggression. The article advocates
the fundamental deconstruction of that “knowledge”, primarily in the academic
field, within the ongoing global processes of decolonization.

Może to być wykonalne tylko wówczas, gdy decyzje w zakresie polityki zagranicznej będą zgodne z tożsamością narodu ukraińskiego. Niektóre cechy w oczywisty sposób zbliżają ukraińską kulturę strategiczną do europejskiej bardziej
niż jakiejkolwiek innej. Jednak dopiero w 1999 r. we Wspólnej Strategii UE dla
Ukrainy pojawiło się uznanie przez Unię europejskiego wyboru Ukrainy. Dyskurs akademicki na temat relacji Ukrainy z UE pokazuje, że Ukraina ucierpiała,
ponieważ jej europejscy partnerzy nie postrzegali jej tak, jak chcieli tego
Ukraińcy. Jeśli jednak bezstronnie przyjrzymy się działalności elit politycznych
Ukrainy, obawy Europejczyków przed takim partnerstwem staną się zrozumiałe:
posługiwanie się „ideą europejską” na Ukrainie było powszechne, ale niezbyt
głębokie. Doprowadziło to do kryzysu zaufania w stosunkach Ukrainy z UE
i strategicznej niepewności obu aktorów co do przyszłego formatu stosunków.
Sama Ukraina na przełomie lat 2013, 2014, jako państwo posiadające wspólne
granice z UE i Federacją Rosyjską, znalazła się pomiędzy konsekwencjami
miękkiej normatywnej europeizacji (w postaci przemian demokratycznych
wewnątrz kraju) a atakiem agresywnego „rosyjskiego miru”. Paradoksalnie wojna Rosji z Ukrainą skłoniła UE do radykalnej zmiany polityki wobec Ukrainy
i zintensyfikowania wsparcia we wszystkich kierunkach, w tym intensyfikacji
dialogu na temat członkostwa w UE. Aby jednak opracować skuteczną strategię,
UE, podobnie jak Ukraina, potrzebuje zasadniczo nowego podejścia, opartego
nie tylko na rozwiązaniu współczesnych problemów związanych z wojną, ale
także na naukowym zrozumieniu specyfiki ukraińskiej tożsamości i głębokich
procesów zachodzących w obrębie transformującego się społeczeństwa
ukraińskiego

Objectives: To investigate how impedance values and sensory thresholds at various human upper limb sites affect the parameter settings of electrical stimulation equipment in low and medium frequency envelope electrical stimulation therapy. Methods: The study involved testing different upper limb sites on 22 healthy subjects (ages 21-25, 11 males and 11 females) by adjusting the modulation wave frequency, carrier frequency, and current intensity of the output. Five types of electrodes of various sizes were used in the tests. Results: The impedance test results for the human upper limb showed a wide range of impedance values across electrodes of different sizes. A new impedance model of the human upper limb was proposed, which accurately fits the relationship between frequency and impedance values. In electrical stimulus sensory experiments, the voltage perception threshold (VPT) introduced in this study was identified as a novel metric for electrical stimulus sensation. Unlike the current perception threshold, VPT does not consider the effects of current magnitude and output frequency. The range of sensory thresholds was 6-8 V, while the suprathreshold was 9-11 V. Neither experiment showed gender differences. Conclusions: Determining the value of the power supply and the output intensity of device power amplification circuitry based on the VPT can provide a more precise therapeutic dose for electrical stimulation therapy.

Published: January 2025

The Visual-inertial navigation system (VINS) integrates visual and inertial sensors, providing advanced navigation capabilities. Recent improvements in these sensors have made VINS widely applicable in areas such as robotic navigation and autonomous driving, due to its complementary functionality and decreasing sensor costs. This paper reviews the latest developments in VINS, introducing visual simultaneous localization and mapping and its role in VINS. Key technologies, including direct and indirect methods for image processing in visual odometry and Inertial Measurement Unit preintegration for robot motion estimation, are discussed. Both filter-based and optimization-based state estimation methods in VINS are examined. Filter-based methods, like the Extended Kalman Filter, offer real-time state updates for attitude tracking and map construction, while optimization-based methods focus on minimizing reprojection or other error metrics to improve localization accuracy and robustness. The application of dynamic simultaneous localization and mapping, which addresses dynamic objects in complex environments, is also explored. This paper summarizes current research challenges and proposes future directions in the field of dynamic simultaneous localization and mapping.

Advancements in finite element analysis for prosthodontics
Authors: Wang Yan , Chen Liwen
Published: January 2025

Finite element analysis (FEA) is a computer-aided tool widely employed in the field of prosthodontics, offering a comprehensive understanding of biomechanical behavior and assisting in the design and evaluation of dental prostheses. By dividing a model into finite elements, FEA enables accurate predictions of stress, strain, and displacement of structures. This review summarizes recent research developments in the application of FEA across various aspects of prosthodontics, including dental implant, removable partial denture, fixed partial denture and their combinations. FEA plays a significant role in selecting restoration materials, optimizing prosthetic designs, and examining the dynamic interactions between prostheses and natural teeth. Its computational efficiency and accuracy have expanded its application potentials for preoperative planning in custom-made prosthodontics. Upon the physician’s assessment of the repair requirements tailored to the individual patient’s condition, FEA can be employed to evaluate the stress distribution, displacement, and other relevant outcomes associated with the proposed restoration. When integrated with clinical expertise, it facilitates assessing design feasibility, identifying necessary adjustments, and optimizing prosthetic solutions to mitigate the risk of failure. Additionally, FEA helps identify potential complications arising from long-term prosthetics use, allowing for the implementation of preventive strategies. Presenting FEA results to patients enhances their understanding of the scientific basis and rationale behind the design, thereby bolstering patient confidence in the proposed intervention. Despite its ongoing limitations, FEA underscores the importance of integrating computational findings with clinical judgment and supplementary diagnostic tools. This review emphasizes the growing role of FEA in advancing prosthodontics by offering computational analysis and design optimization, ultimately improving treatment outcomes and patient satisfaction.

Authors: Agnes Putri Rhulina Br. Ginting  , Purwaningrum Lu'lu'
Published: January 2025

Daycare is a public facility that not many people know about or use currently. Even though daycare can be a support for parents who work and don't have a nanny. Even though several daycares have been established in Jakarta itself, the concept presented at this daycare is very different. The current condition of Jakarta, which is increasingly congested and air pollution is quite high, is one of the reasons for designing this daycare. Daycare is designed not only as a supporting facility, but as a place that can support children's development and growth. This design uses a biophilic minimalist concept, where this concept presents a natural concept combined with a minimalist concept that is suitable for children.

Published: January 2025

Actinomycetes are Gram-positive bacteria with morphological characteristics in the form of unicellular filaments that have the potential to dissolve bound phosphate into a form available to plants. This study aims to isolate and identify phosphate-solubilizing Actinomycetes from the rhizosphere of corn (Zea mays) in Gorontalo, Indonesia. Rhizosphere soil samples were taken at a depth of 15-30 cm from three corn farming locations in Mohiyolo Village, Asparaga District. Parameters analyzed included environmental characteristics, isolate morphology, phosphate solubility index, and soluble phosphate concentration. Identification was based on the morphology of aerial mycelium and substrate mycelium, as well as physiological tests of phosphate solubilization ability. Phosphate solubility index was calculated from the ratio of halo zone diameter to colony on Pikovskaya agar medium, while soluble phosphate concentration was measured using spectrophotometry. The results showed that RFZm-Pg isolate had the highest solubility index of 2.98 mm, while RFZm-Pw isolate was 1.54 mm. The highest dissolved phosphate concentration in liquid media was 2.0929 ppm (RFZm-Pg) and 1.0744 ppm (RFZm-Pw). The phosphate-solubilizing Actinomycetes isolates obtained have potential as biofertilizers, so further testing is needed.

Karst areas are landscapes composed of carbonate rocks and are rich in calcium and magnesium elements, making some macronutrients unable to be absorbed by plants directly. One of the soil microorganisms associated with plants in karst areas is Actinomycetes. Some species of Actinomycetes are known to produce growth hormones such as Indole Acetic Acid and dissolve phosphate bound in the soil. Actinomycetes also play an important role in soil ecosystems, especially in areas with extreme environmental conditions such as karst areas. Karst areas are known for their unique biodiversity and the potential of microorganisms that have not been fully explored. Gorontalo karst area is a potential location for the exploration of these microorganisms. This study aims to isolate and characterise Actinomycetes found in the rhizosphere of plants in Gorontalo karst area. Sampling was carried out on 9 plant species found in two locations namely Tanjung Kramat, Hulonthalangi District and Karst Mountains. Macroscopic characterisation results showed that the Actinomycetes isolates obtained had 2 forms, namely Irregular (5 isolates) and Circular (4 isolates) with mycelium colour dominated by greyish black - brown, orange-orange, yellow-orange, grey-yellow, and white - yellow. Microscopic characterisation showed the results of all isolates obtained were blue or purple with thin filamentous cells indicating the isolates were Actinomycetes.
