Authors: Afandi Nuramalina
Published: May 2023

Smooth, even-complexed and radiant skin without wrinkles and dark spots characterizes healthy skin. Ageing is a natural biological process of becoming older. As a largest organ in the body, skin is prone to aging due to exposure to the external and internal damages. Skin ageing is characterized by wrinkles, fine lines and dark spots that appear on the skin surfaces. Cosmetics nowadays not only associated with beauty but also younger looking skin. The demand for anti- ageing cosmetics with natural ingredients are projected to boost the cosmetics industry contributing to global market growth due to an increase in global ageing populations. There are many cosmetics in the market offered product line for anti-ageing. Despite giving positive result in a longer period, natural ingredients are more preferred as active ingredients compared to synthetic ingredients which are notoriously known for causing complications as mild as minor irritations to more severe anaphylactic reactions, lethal poisonings, or long-time effects to users due to accumulated toxins. In this study, natural active ingredients will be discussed in terms of their sources, mechanisms, and anti-ageing properties. Systematic searches of PubMed, ScienceDirect, NCBI and Medline databases were carried out using various keywords. Through screening, 40 studies out of 70 studies were selected. Based on this review, a large variety of natural active ingredients could be obtained from plants, animals, and marines compared to singly synthesized artificial alternatives. The benefits, safety and efficacy of the ingredients were also evaluated, and it is found that they are indeed better constituents compared to synthetic ingredients to be used in cosmetic formulations.

Authors: Grosseli Eduarda , Weirich Ribeiro Inaua , Vier Munhoz Angélica
Published: May 2023

O presente artigo deriva de um projeto de pesquisa vinculado ao Grupo de Pesquisa Currículo, Espaço, Movimento, da Universidade do Vale do Taquari - Univates. Esta investigação foi realizada por uma bolsista de iniciação científica, em conjunto com uma bolsista de doutorado do Programa de Pós-graduação em Ensino  da mesma Universidade, orientadas pela professora coordenadora do Grupo. O objetivo da pesquisa foi arquivar e arquivizar as teses de doutorado da Área de Conhecimento em Ensino (publicadas no período de 2013 a 2020) que operam com a noção de aula na formação inicial de professores no Catálogo de Teses e Dissertações da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior. Para tanto, utilizou-se, como referencial teórico-metodológico, a noção de arquivo de Michel Foucault. Como procedimentos arquivísticos, operou-se com os dispositivos de arquivamento e arquivização, a partir de Aquino e Val. Dispondo do arquivo e dos demais procedimentos citados, foi possível observar os enunciados correspondentes às noções em destaque – aula e formação inicial de professores. A investigação não tem a intenção de exibir uma definição das noções; todavia, evidenciou o modo como elas emergiram nesse arquivo. Dessa forma, verifica-se, como resultado, uma quase-invisibilidade das noções de “aula” e de “formação inicial de professores” na produção de teses de doutorado da Área de Conhecimento em Ensino no Brasil (período de 2013 a 2020).

A Harkányi-sík gyertyános-tölgyesei (Corydali cavae-Carpinetum Kevey 2008)
Authors: Kevey Balázs
Published: May 2023

This paper presents the phytosociological characteristics of the oak-hornbeam forests on the Harkány plain based on an analysis of 25 phytosociological samples. These forests are only weakly influenced by groundwater, and thus exhibit features of dry oak forests. They sharply differ from the oak-hornbeam forests (Veronico montanae-Carpinetum) growing on young alluvial deposits in the neighboring Drava plain. In species composition, they most resemble the oak-hornbeam forests (Corydali cavae-Carpinetum) of the also neighboring Nagynyárád plain that is covered with loess. Thus, as an association, they are identified with the latter. Owing to the sporadic occurrence of Aremonio-Fagion elements (Lonicera caprifolium, Luzula forsteri, Primula vulgaris, Tamus communis, Tilia tomentosa), this association exhibits a moderate sub-Mediterranean character.

Embedding the watermark is still a challenge in image watermarking. The watermark should not reduce the visual quality of the image being watermarked and hard to distinguish from its original. Embedding a watermark of a small size might be a good solution. However, the watermark might be easy to lose if there is any tampering with the watermarked image. This research proposes to increase the visual quality of the watermarked image using the Walsh Hadamard transform, which is applied to the singular value decomposition-based image watermarking. Technically, the watermark image is converted into a low bit-rate signal before being embedded in the host image. Using various watermark sizes, experimental results show that the proposed method could produce a good imperceptibility with 47.10 dB on average and also gives robustness close to the original watermark with a normalized correlation close to 1 on average. The proposed method can also recognize the original watermark from the tampered watermarked image at different levels of robustness.

The current study employs the finite element method to compare stress concentration pertaining to a graphite / epoxy rectangular laminated composite plate that possess holes in different shapes. The hole enables redistributing in-plane stresses, impacts the stress concentration factor (SCF), and focuses maximum stress near the hole. The ANSYS program has been designed to be employed for parametric studies pertaining to plates that have a hole under uniaxial in-plane load. Analysis was done for angle-ply, four-layered symmetrically laminated rectangular plates that include different stacking sequences ± θ.

Anchovy is one of the economically important fish in the western part of the northern coast of Central Java. The production of anchovies extends along the coast from Brebes Regency to Batang Regency. Therefore, this study aims to determine the diversity of anchovies on the northern coast of Central Java (Brebes, Tegal, Pemalang, Batang, and Kendal), using a molecular approach. This study was conducted from April to September 2019 in the Laboratory of Tropical Marine Biotechnology, Faculty of Fisheries and Marine Science, Universitas Diponegoro. The descriptive exploratory method was applied in this study with a random sampling technique, while the cytochrome oxidase I (COI) gene was used for molecular identification. An anchovy sample molecularly identified from each region was found by sampling, including BB 3, PML 2, BTG 1, BTG 2, BTG 4, TGL 2, TGL 4, KDL 1, and KDL 4. The base-pair length of 10 anchovy samples from the COI gene amplification result was 600-700 bp. The sequencing and alignment results of the BLAST analysis showed that the ten anchovy samples were included in the type of Encrasicholina heteroloba, Stolephorus commersoni, Stolephorus waitei and Atherinomorus sp., which ranged from 98 to 99% similarity in location. Therefore, it is concluded that there were at least four different species of anchovy on the northern coast of Java. However, further research is suggested to determine the genetic variation of each species for better fisheries management.
IGF-1 and IGFBP3 as indirect markers of hepatic insulin resistance and their relation to metabolic syndrome parameters in liver steatosis patients
Authors: Fraenkel Emil , Lazurova Ivica
Published: May 2023

Objective. The aim of the present study was to assess insulin-like growth factor 1 (IGF-1) and IGF-binding protein 3 (IGFBP3) as markers of insulin resistance in patients with prediabetes and type 2 diabetes mellitus (TDM2).

Patients and Methods. This observational clinical study included 76 obese/overweight patients at the age of 45–75 years with T2DM on oral diabetic medication and ultrasonographically or by a computerized tomography (CT) diagnosed liver steatosis. Correlation analysis was performed between plasma levels of insulin, C-peptide, IGF-1, IGFBP3 and HOMA indexes on the one hand and between plasma levels of ALT, AST, triglyceride, cholesterol, and HDL cholesterol and body mass index (BMI) of patients on the other hand. In case of significant partial correlation coefficients, a multiple linear regression model with IGF-1 and IGFBP3 used as outcome variables adjusted for age and sex groups was calculated. According to these regression models, ROC curves were prepared with HOMA index=3 used as a classificator of insulin resistance.

Results. Significant correlation was found between C-peptide and IGF-1 (r=0.24, p≤0.05), C-peptide and IGFBP3 (r=0.24, p≤0.05), IGFBP3 and cholesterol (r=0.22, p≤0.05) IGFBP3 and ALT (r=0.19, p≤0.05), HOMA index and triglycerides (r=0.22, p≤0.05), and HOMA index and ALT (r=0.23, p≤0.05). Significant correlation adjusted for age and gender was found between C-peptide and IGF-1 plasma levels (R2=0.20, p<0.05) with AUROC 0.685 (p≤0.01) and C-peptide and IGFBP3 plasma levels (R2=0.28, p<0.05) with AUROC 0.684 (p≤0.01). Significant correlation adjusted for age and gender was found between triglyceride and IGFBP3 plasma levels (R2=0.28, p<0.05) with AUROC 0.616 (p≤0.01). After the distribution of patients according to their IGFBP3 levels, we found a difference between the 1st and the 4th quartiles in terms of triglyceride levels.

Conclusion. Our results demonstrate a fundamental role of IGF-1 and IGFBP3 in the patho-physiology of hepatic insulin resistance and suggest them as indirect indicators of the hepatic insulin resistance.

The 3D model of a building was built to analyze the scene of a fire with reference to the real situation. The process of evolution of a fire was simulated with FDS. The evolution time of the fire, the degree of danger, the temperature as well as the visibility was analyzed. Architectural solutions that could be considered for the prevention and evolution of fire in the presented situations were also analyzed. The results of the simulations in the proposed scenarios showed that solutions could be found to prevent the spread of fire. The results of the study provide a real base for improving the evacuation conditions and limiting the damage caused by fire in single-family buildings.
Influence of biochar on improving hydrological and nutrient status of two decomposed soils for yield of medicinal plant - Pinellia ternata
Authors: Ng Charles Wang Wai , Touyon Lisa , Bordoloi Sanandam
Published: May 2023

The root tuber of Pinellia ternata has been used as a traditional therapeutic herbal medicine. It is reported to impart beneficial attributes in recovering COVID-19 patients. To meet an increasing demand of P. ternata, this study is intended to investigate the effects of biochar on the soil hydrological and agronomic properties of two decomposed soils (i.e., completely decomposed granite (CDG) and lateritic soil) for the growth of P. ternata. The plant was grown in instrumented pots with different biochar application rate (0%, 3% and 5%) for a period of three months. Peanut shell biochar inclusion in both soils resulted in reduction of soil hydraulic conductivity and increase in soil water retention capacity. These alterations in hydrological properties were attributed to measured change in total porosity, biochar intra pore and hydrophilic functional groups. The macro-nutrient (i.e., N, P, K, Ca, and Mg) concentration of both soils increased substantially, while the pH and cation exchange capacity levels in the amended soils were altered to facilitate optimum growth of P. ternata. The tuber biomass in biochar amended CDG at all amendment rate increases by up to 70%. In case of lateritic soil, the tuber biomass increased by 23% at only 5% biochar application rate. All treatments satisfied the minimum succinic acid concentration required as per pharmacopoeia standard index. The lower tuber biomass exhibits a higher succinic acid concentration regardless of the soil type used to grow P. ternata. The biochar improved the yield and quality of P. ternata in both soils.
Challenges of Post-Pandemic Urban Resilience Management
Authors: Badea Dorel , Ranf Diana Elena
Published: May 2023

The crisis caused by the Covid pandemic is certainly the major disruptive event of this first quarter century, the Russian-Ukrainian military crisis also having the potential (in terms of the global dysfunctions generated) to fit into this typology. Beyond the clear negative effects (social, human, economic, etc.) of the Covid pandemic, however, we must also consider the possible challenges it may pose. The research question of the present article is situated in this thematic register, on a niche topic, urban resilience, re-evaluated, following the materialization of this pandemic context, both in academic research and in terms of contemporary management practice. It is intended, in conjunction with a bibliometric analysis, to highlight possible directions of action within the triple and quadruple helix models for strengthening urban resilience based on the lessons learned from this crisis, directions that are considered useful to a wide range of stakeholders in academia, industry and government. While there is sufficient concern directed towards determining resilience indices, the main thesis considered for this article is that there is a need for synergistic stakeholder action, integrating such elaborations into the proactive framework of a robust yet scalable urban resilience profile in relation to a wide range of events across the urban community security threat spectrum, as was the case with Covid 19.
