Influence of abiotic factors on the variability of the seedling – flowering period in the parental components of maize hybrids
Authors:   State Enterprise Institute of Grain Crops of NAAS, Svinitskyi L. M.
Published: August 2023

Topicality. Maize is a monoecious cross-pollinated plant with a well-defined proterandry, however, some maize samples show persistent proterogyny. A significant manifestation of proterandry and proterogyny tends to negatively affect the pollination quality of ears and the yield of lines during reproduction. Synchronisation of flowering the ear in the female component and the tassel in the male component is essential for the reproduction of sterile analogues of self-pollinated lines and for production of F1 hybrid seeds. Since the lack of coincidence in flowering dates can cause poor pollination and the formation of ears with incomplete kernel set and further loss of seed yield. Purpose. To determine the variability of the seedling – flowering period of female and male inflorescences of parental components in maize hybrids under the influence of abiotic factors. Materials and Methods. The research was conducted at the Institute of Grain Crops of NAAS of Ukraine during 2018–2021. In the experiment, 15 parental components of maize hybrids were used: DK216M sterile, DK216SVZM, DK273MV, DK777M, DK777ZMSV, DK680MVZS, DK315M sterile, DK315SVZM, DK239MV, NT 004 sterile, NT 004 fastener, TT005, DK2064M, DK2064SVZM, DK633/325 MV. The flowering date for inflorescences of parental components was recorded at flowering of 50% of plants on the plot. Results. The agrometeorological conditions were quite contrasting over the years of research, which allowed us to comprehensively assess the variability of the seedling-flowering period of female and male inflorescences in the parental components of maize hybrids. We found that the parental components were differently sensitive to environmental changes; the dichogamy of flowering of male and female inflorescences in most maize genotypes has traits of proterandry. Proterogyny was observed in some samples under cool weather conditions with high precipitation. Conclusions. We found that abiotic factors affect the variability of the seedling-flowering period for female and male inflorescences in the parental components of maize hybrids, however, in our experiments, the variability of the seedling-flowering period in maize was very low. The obtained results indicate the possibility for reliable seed production of maize hybrids DN Synevyr, DN Svitiaz, DN Halateia, Monika 350 MV, DN Vesta in the Steppe of Ukraine.

Topicality. In the context of global warming and climate changes, it is important to substantiate, develop and implement agrotechnical practices to mitigate the negative effects of drought, heat and soil moisture deficit. The solution to these problems is to find ways to optimise the growing conditions of maize (Zea mays L.), using the adaptive properties and agrocenotic resistance of new hybrids to adverse environmental stressors with rational management of the growing season and agroclimatic resources of soil and ecological zones. Sowing methods and plant density, as well as other technological factors, play an important role in the complex of zonal agrotechnical practices. Maize plants demonstrate considerable biological plasticity in interaction with environmental conditions. The life support processes of maize plants depend on ecological changes caused by the quantitative and spatial placement of maize plants in the crop. The variability of the size and configuration of the individual plant nutrition area is limited primarily by the plant's requirements for environmental factors that ensure their normal growth, development and high productivity. Purpose. The research was aimed to identify the peculiarities of plant growth and development, as well as the formation of maize grain yield depending on the method of sowing and plant density in the Northern Steppe of Ukraine. Materials and Methods. The research was carried out at the Experimental Farm "Dnipro" of the State Enterprise of the Institute of Grain Crops of NAAS. The soil was ordinary low-humus full-profile chernozem. The mid-early maize hybrid DN Stiah was sown with row spacing of 30, 45 and 70 cm at plant density of 40, 50, 60 and 70 thousand plants/ha, fertiliser background – N60P45K45. Results. Sowing methods and plant density influenced the structural elements of the yield and maize grain yield. In 2019–2021, the highest average maize yield (11.13 t/ha) for factor A (sowing method) was obtained by sowing with row spacing of 30 cm. Increasing the row spacing to 45 and 70 cm led to a decrease in the grain productivity of the maize hybrid DN Stiah by 0.21 and 0.75 t/ha (i.e. by 1.9 and 6.7 %), respectively. For factor B (planting density), the highest average grain yield (11.03 and 10.95 t/ha) was obtained at a planting density of 60 and 50 thousand plants/ha, respectively. Conclusions. In the face of resource constraints, narrower row spacing in maize cultivation may have the potential to increase the level of realisation of hybrid productivity potential.

Published: August 2023

The conceptual and categorical apparatus of “cooperative security” is investigated and three main approaches to the interpretation of the security concept components are substantiated. As the result of scientific research, the main goals of cooperative security are identified. The general characteristics of the concept of cooperative security in the context of practice-oriented application of “security triangle” are justified. On this basis, the actualization of the application of appropriate vectors is established in order to eliminate the requirements of the states being at risk of taking appropriate countermeasures. It is established that the concept of cooperative security is based on the principles of strengthening security by means of cooperation, and the main element is the system of collective security with more developed political and legal mechanisms. It is proved that under modern conditions there is the need for constant search of optimal models or concepts of international security. It should be noted that there is no ideal solution, since security requires requires reconciling the expectations of individual states with different statuses and interests.

Published: August 2023

The popular association rule algorithms are Apriori and fp-growth; both of these algorithms are very familiar among data mining researchers; however, there are some weaknesses found in the association rule algorithm, including long dataset scans in the process of finding the frequency of the item set, using large memory, and the resulting rules being sometimes less than optimal. In this study, the authors made a comparison of the fp-growth, Apriori, and TPQ-Apriori algorithms to analyze the rule results of the three algorithms. TPQ- Apriori is an algorithm developed from the Apriori algorithm. For experiments, the Apriori and fp-growth algorithms use RapidMiner and Weka tools, while the TPQ-apriori algorithm uses self-built application programs. The dataset used is the sales data for the Kopegtel NTB department store, which has been uploaded on the Kaggle site. As for the results of testing the base rules from the overall results of testing the rules with the good Kopegtel dataset for 100%, 50%, and 25% of the total volume of the dataset, a conclusion can be drawn that the larger the dataset to be processed, the results will be more optimal when using the fp-growth algorithm RapidMiner, but not optimal if the dataset to be processed is small. It is different from using the Apriori and Weka FP-growth algorithms, where the resulting rules are less than optimal if the dataset used is large and optimal if the dataset is small. Several rules do not appear in the fp-growth and Apriori Weka algorithms because the two algorithms do not have a tolerance value in Weka's tools for the support of the rules that will be displayed. Meanwhile, the TPQ- Apriori algorithm that has been developed is capable of producing optimal rules for both large datasets and small datasets.

Actual Problems of Economics Teaching in Higher School
Authors: Stepanova S. V.
Published: August 2023

The article examines the current problems of teaching economic specialties in Russian universities. According to the author, modern higher economic education is not focused on training specialists with the knowledge and values necessary to solve the problems of ensuring the economic sovereignty of the country. The reasons for this are both inside and outside the education system. To identify these causes and areas of concentration of problems, the author analyzed the current admission rules approved by universities in accordance with the regulatory documents of the Ministry of Education and Science; approaches to the assessment of applicants; the content of educational programs, their relationship with professional standards; curricula in the areas of training 38.03.01 “Economics”. The study used publicly available information posted on the websites of universities-leaders of the Expert RA Rating Agency ranking for 2020 in economics and management. The analysis revealed areas where the problems of higher economic education have a high degree of concentration. These include: the lack of uniform requirements for the initial knowledge of applicants; heterogeneity of the quality of the student audience by the level of initial knowledge; the inability of professional standards to orient universities to the formation of popular educational programs; the predominance of mathematical disciplines in the curricula, while reducing the list and volume of disciplines that form the worldview; unjustified shift of emphasis towards financial disciplines, formation of calculation skills instead of obtaining fundamental economic knowledge. Awareness of these problems will make it possible to make changes to curricula purposefully, and university graduates will be quickly involved in solving problems related to ensuring the economic sovereignty of the country, along with representatives of technical specialties.

Authors: Jaworski Bogdan
Published: August 2023

W czasach otwartych granic, gdy Polska jest członkiem Unii Europejskiej i Strefy Schengen przemieszczanie się ludności nie tylko wewnątrz kraju, ale głównie pomiędzy państwami stało się czymś naturalnym, a wręcz niezbędnym do normalnego funkcjonowania. Znaczna część ruchu osobowego, ale także towarowego odbywa się drogą powietrzną, przy wykorzystaniu licznie funkcjonujących w Polsce lotnisk komunikacyjnych.
Masowy przepływ osób skutkuje występowaniem wielu zagrożeń i koniecznością zapewnienia bezpieczeństwa w różnym stopniu i wymiarze. Przystępując do badań należy postawić tezę, że za bezpieczeństwo, spokój i porządek publiczny na lotniskach komunikacyjnych odpowiadają w głównej mierze formacje mundurowe. Przedmiotem rozważań w niniejszym opracowaniu są podstawy prawne oraz działalność takich formacji jak: Straż Graniczna, Policja, Służba Celno-Skarbowa, służba ochrony lotniska oraz lotniskowa służba ratowniczo-gaśnicza. Mają one za cel czuwanie nad bezpieczeństwem, spokojem i porządkiem publicznym na terenie lotnisk oraz obszarze przyległym.
Artykuł ma charakter przeglądowy, a zawarte w nim rozważania oparte zostały w głównej mierze na materiale normatywnym. Zdaniem Autora brak jest kompleksowych opracowań dotyczących roli, jaką spełniają formacje mundurowe w kształtowaniu bezpieczeństwa na lotniskach dlatego warto zwrócić uwagę na najważniejsze aspekty z tym związane.

Published: August 2023

In order to further promote the trade development of western China towards the “Belt and Road”, identify the countries for building international logistics hub, and construct the cross-border logistics hub network of western China along the “Belt and Road” are urgently needed. This paper proposes a two-stage method to study the construction of cross-border logistics hub network. In the first stage, 27 nations are initially selected using the fuzzy C-means clustering approach. These 27 nations enjoy better trading conditions and higher trade volumes with China than other the “Belt and Road” cooperation nations. In the second stage, this paper puts forward the maximum criterion of logistics gravity based on the gravity model, and objectively determines 14 countries for building international logistics hub. These nations, which include China, Russia, the United Arab Emirates, and others, have a high degree of international logistics development and robust logistics interconnection. According to the logistics connecting countries of these 14 countries, the logistics circle is divided. This paper connects China with other hub countries in the logistics circle, then the cross-border logistics hub network is constructed.

Authors: Charnvanichborikarn Patara , Kantanatha Nantachai
Published: August 2023

The world has seen a dramatic change in weather patterns caused by global warming. Extreme weather and unpredictable events are occurring more often. As weather is the most unpredictable component of a flight, if there is a slight chance of predictability in what the weather is going to be, it could help with the logistical issues and prevent further delays. Therefore, aircraft arrival prediction could potentially be a solution to improve the efficiency of the operation and the effectiveness of the contingency plans to respond to such events. The objective of this paper was to gain more insights and study the effect of weather on aircraft arrival delay by using random forest classification method and adaboost classification method. The results show that random forest classifier is the most accurate model for the weather delay prediction with the accuracy of 92.98 percent. When comparing F-1 score with adaboost, random forest model also gives higher values for all conditions.

This research presents a technique for counting the number of people in a smart office room when walking in and out of the door by relying on a normal quality webcam. This means that the camera is not high resolution. The picture is not clear and sharp. Therefore, the image must be counted to adjust the color first before being processed in other steps. The designed system uses OpenCV and Raspberry Pi to help and is Edge Computing processing by comparing images in front view and top view. The front view is accurate at 58.44% for entering the room and 30.15% accurate for leaving the room. However, it was clear that the top view image would be more accurate at 87.82% for walking into the room and 80.75% out of 130 tests for walking out of the room. This system can also be used for counting people in other situations, such as counting people in factories, counting workers on the job site and counting people at trade fairs, etc.

Authors: Wang Ruikun , Huang Zhihong , Cai Gang , Yu Zhong
Published: August 2023

FinFET memory is widely used in various semiconductor products due to its good read/write margin, lower power consumption, and faster driving speed. However, the forked 3D physical structure and the increased density of storage are very susceptible to manufacturing defects, which may cause memory functional logic faults that are different from traditional planar CMOS memories. Therefore, it is critical to explore an effective test method for FinFET memories. This paper proposes a MBIST circuit for detecting functional faults of FinFET memory. The proposed circuit is based on the March FRDD algorithm and performs well in detecting resistance dynamic faults. The area of this circuit is 85.3286 µm2, which benefits from the design method of multiplexing the internal part of the circuit. The total fault coverage of the MBIST circuit reaches 91.7%, which provides great convenience for FinFET memory testing.

Authors: Gao Xuehong , Huang Guozhong , Jiang Huiling , Zhou Liang
Published: August 2023

In the early response to large-scale epidemics, it generally leads to an imbalance in emergency relief resources among different regions. In this sense, these emergency relief resources need to be wholly reallocated to balance supply and demand, which can be realized by a collaborative emergency relief resource reallocation process with the maximization of fairness. To address this issue, a stochastic nonlinear optimization model is proposed to formulate the collaborative emergency relief resource reallocation problem under uncertainty. Then, a linearization strategy is developed to determine the global optimum. To validate the proposed model, a real case study is implemented to obtain the profound managerial implications and actionable insights, representing the primary requirements and benefits of this study.

Authors: Gu Jing , Li Ying-hui
Published: August 2023

To address the issue of the SPP structure in the YOLOX network being unable to perfectly express the spatial structure of diseases during bridge disease detection, resulting in poor detection performance for irregular and elongated targets, a YOLOX bridge disease detection algorithm based on CS pooling is proposed. The algorithm uses cross-pooling and strip-pooling on the output feature map of the Backbone, and then fuses them, fully combining the local and elongated features as well as the spatial location features of the feature map, improving the expressive ability of the feature map, making it more suitable for bridge disease detection. The experimental results show that the improved model based on CS pooling YOLOX achieves better detection results, with a 2.61% improvement in detection accuracy compared to the YOLOX network, and the detection accuracy of cracks and weathering is the highest. This verifies the effectiveness of the algorithm.

Historical Pathogen-Driven Selection May Contribute to Contemporary Ethnic Difference in Bladder Cancer Susceptibility
Authors: Meng Xiang-Yu , Wang Qiao-Li , Shi Ming-Jun , Zhang Hong-Yu
Published: August 2023

BACKGROUND:

The rationale for ethnic differences in bladder cancer (BCa) susceptibility is an important open question. In this study, we raised the hypothesis that the APOBEC3-rs1014971 variant associated with BCa risk and APOBEC-mutagenesis probably contribute to ethnic differences.

METHODS:

We calculated the ethnicity-stratified 5-year age-adjusted incidence rates of BCa using the US SEER database. We performed somatic mutational-signature analyses and compared the APOBEC-related mutational contribution across BCa tumors in patients of different ethnicities. We analyzed the allele frequency distribution of APOBEC3-related rs1014971 in contemporary populations of different ethnicities and in ancient human genomes. We also analyzed the natural selection profiles and ages of the investigated SNPs.

RESULTS:

We validated the ethnic difference in BCa risk using US SEER data, revealing Caucasians to be at >2-fold greater risk than Asians / Pacific islanders. In contemporary populations, we observed a coherent ethnic distribution in terms not only of the allele frequency of APOBEC3-related rs1014971, but also the mutational contribution of APOBEC-mediated mutagenesis in BCa tumors. Population genetics and ancient genome analyses further suggested that the diverse ethnic distribution of rs1014971 could be rooted in human evolution.

CONCLUSIONS:

It is possible that APOBEC3-related rs1014971 is involved in the different BCa incidence across ethnic groups, and this difference is potentially derived from human evolution. Our findings suggested an evolutionary link between contemporary population-level variations in malignancy susceptibility and pathogen-driven selection in the past, not unlike previously reported cases of certain autoimmune and metabolic disorders.

BACKGROUND: Bovine pericardium (BP) is a scaffold widely used in soft tissues regeneration; however, its calcification in contact with glutaraldehyde, represent an opportunity for its application in hard tissues, such as bone in the oral cavity. OBJECTIVE: To develop and to characterize decellularized and glutaraldehyde-crosslinked bovine pericardium (GC-BP) as a potential scaffold for guided bone regeneration GBR. METHODS: BP samples from healthy animals of the bovine zebu breed were decellularized and crosslinked by digestion with detergents and glutaraldehyde respectively. The resulting cell-free scaffold was physical, chemical, mechanical, and biologically characterized thought hematoxylin and eosin staining, DNA quantification, scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), uniaxial tensile test, cell viability and live and dead assay in cultures of dental pulp stem cells (DPSCs). RESULTS: The decellularization and crosslinking of BP appeared to induce conformational changes of the CLG molecules, which led to lower mechanical properties at the GC-BP scaffold, at the same time that promoted cell adhesion and viability of DPSCs. CONCLUSION: This study suggests that the decellularized and GC-BP is a scaffold with the potential to be used promoting DPSCs recruitment, which has a great impact on the dental area.

Published: August 2023

The fuel cell-dependent electric vehicle systems are giving an important role in the present automotive systems because their features are less air pollution, high flexibility, reduced oil dependency, and more reliability. However, the fuel stack delivers nonlinear output V-I characteristics. So, the extraction of peak power from the fuel source is very difficult. In this work, a Variable Step Size Radial Basis Functional Network-based Adaptive Fuzzy Logic Controller (VSSDE-AFLC) is proposed for tracking the peak power point of the fuel cell system. The merits of the proposed Maximum Power Point Tracking (MPPT) controller are high tracing speed of functioning point of the fuel cell, more flexibility, high abundant, acceptable oscillations across MPP, and less dependency on modeling of the fuel stack. Also, the single switch converter is utilized for increasing the voltage supply of the fuel cell. The features of the proposed converter are wide input operation, less voltage stress, high supply voltage conversion ratio, and good dynamic response. The proposed fuel cell-dependent boost converter is implemented by utilizing the MATLAB/Simulink software, and the converter is tested successfully by using the desired programmable DC supply.

Our target in the present work, is presenting the idea of weakly soft preopen (ws-preopen) subsets and studying some of its characterizations. With the assistance of some elucidative examples, the interrelationships between ws-preopen sets and some extensions of soft open sets are studied. Under some conditions such as extended and hyperconnected soft topologies, several motivating results and relationships are acquired. The interior and closure operators that built through ws-preopen and ws-preclosed subsets are introduced. Their main features that construe the relations among them are established. Soft continuity with respect to theses classes of soft subsets are studied and their substantial characteristics are investigated. Generally, the systematic relations and outcomes that are lost through the scope of this study are discussed. The proposed line in the current study will present new ways to discover novel concepts in the field of soft topology.

Authors: Zheng Yunchao
Published: August 2023

Traditional Chinese art is vast and profound, with various colors having rich meanings. The combination of colors can vividly and intuitively represent various characteristics of things. Fully reflecting the characteristics of traditional Chinese folk art in graphic design can achieve extremely strong expressive effects. In current graphic design, the artistic colors of traditional Chinese folk art have not yet been fully displayed, and there is a lack of understanding of the profound connotation of traditional Chinese art. The graphic design industry has a very broad development space. The comprehensive evaluation of graphic design effects based on color psychology is a classical multiple attribute group decision making (MAGDM) problems. In this work, we shall present some novel Dice similarity measures (DSM) of T-spherical fuzzy sets(T-SFSs) and the generalized Dice similarity measures (GDSM) of and indicates that the DSM and asymmetric measures (projection measures) are the special cases of the GDSM in some parameter values. Then, we propose the GDSM-based MAGDM models with T-SFSs. Then, we apply the GDSMs between T-SFSs to MAGDM. Finally, an illustrative example for comprehensive evaluation of graphic design effects based on color psychology is given to demonstrate the efficiency of the GDSMs. The main contributions of this paper are summarized: (1) some novel Dice similarity measures (DSM) and the generalized Dice similarity measures (GDSMs) of T-spherical fuzzy sets(T-SFSs) are proposed; (2) The weighted Dice similarity measures (WDSM) and the weighted generalized Dice similarity measures (WGDSMs) of T-spherical fuzzy sets(T-SFSs) are proposed to solve the MAGDM; (3) an illustrative example for comprehensive evaluation of graphic design effects based on color psychology is given to demonstrate the efficiency of the WGDSM; (4) Some comparative analysis are used to show the effectiveness of the proposed Dice similarity measures.
The Evolution of Public Surveillance Systems in Europe
Authors: Tóth Levente
Published: August 2023

Video surveillance systems are used today in many parts of the world in public spaces. Although most publications date the appearance of the systems in public spaces to the 1980s, the use of the systems by the British police dates back 60 years. However, the actual spread of these systems has only been significant since the 1990s, as the development of technology made it possible to produce images of a quality that can be well utilised for the suppression and detection of crime through constant and intensive surveillance of public spaces at a cost-effective price. The speed of spread, size of infrastructure, mode of supervision and use, and the purpose of installation of the systems vary from country to country in Europe. This is mainly determined by the political, social, criminal, economic and legal context of the country.

Background: Hospital preparedness for accidents and disasters is vital in maintaining and promoting community health. However, the country’s hospitals are not well prepared for disasters. The hospital safety index (HSI) was 42% in Iranian hospitals in 2014. This study aims to investigate the HSI in Iranian hospitals in 2020 and to provide solutions to improve it. Materials and Methods: This cross-sectional descriptive study was performed for the country’s hospitals. The results recorded in the Farsi version of the hospital safety index (FHSI) software in 2020 were used. Hospital teams used the FHSI checklist (151 options) in three areas of structural, non-structural, and functional safety to assess the hospital and register in the FHSI system. The registered results of the hospitals were collected based on the medical universities of the country. Descriptive statistics were used to analyze the data. Results: A total of 604 hospitals registered safety index information in the system. The mean score of the HSI of the country’s hospitals was 60.84. A total of 130 hospitals (21.5%) had low safety levels, 418 hospitals (69%) had moderate safety levels, and 56 hospitals (9.2%) had high safety levels against disasters. The mean scores were in structural safety (57.20), non-structural (65.24), and functional safety (63.36). Hamedan (76.81) and Kerman (75.61) Provinces had the highest score, and Yazd (53.74), and Lorestan (57.31) Provinces had the lowest score in the country. Conclusion: The HSI against disasters in 2020 compared to 2014 has reached 6 out of 10 and we have about a 41.5% increase in safety (from 43 to 60.84). However, the HSI is moderate. Strengthening the safety and resilience of hospitals, improving the safety of medical equipment, improving the knowledge and skills of managers in the scientific development of preparedness, response and recovery programs, funding and support of crisis programs, attention to security programs, pollution, and evacuation are among the solutions of development and enhancement of hospital preparedness against disasters.

Internet of Things (IoT), which connects billions of devices and services to the Internet, is viewed as the future industrial and intellectual revolution in technology. These connected devices are available in a variety of types. Different technologies and standards use various protocols to interact with each other. Due to these difficulties with heterogeneity, the application of IoT on a broad scale is difficult. This inspired us to identify the problems from the literature and offer solutions to solve the IoT scalability problem. This study is based on the systematic literature review (SLR) to identify the diverse problems and their solutions. We chose 81 primary sources in total. We found 14 distinct IoT heterogeneity concerns after extracting and interpreting the data. The following issues have been noted as potential obstacles: heterogeneity in data formats, heterogeneity of devices, heterogeneity in communication, and interoperability difficulty because of heterogeneity. From the perspectives of digital libraries and timeframes, the stated challenges have been addressed. Additionally, we have discovered 81 solutions in total for these problems, with at least 5 different answers for every issue. In the future, we will use a multi-criteria decision-making issue to classify the problems and evaluate the solutions.

Recurrent Aphthous Stomatitis (RAS) is a prevalent oral disease that detrimentally impacts the quality of life for those affected. One of the several factors that can trigger the emergence of RAS is stress. Psychological stress can adversely affect health and decrease the immune system. Studies in the field of Psychoneuroimmunology have shown the relationship between human behaviour, nerve function, and psychological stress, which can potentially act as a cause of disease and reduce the immunity of the oral mucosa. Therefore, this study aimed to determine the correlation between stress and the incidence of Recurrent Aphthous Stomatitis on Bank BRI Tulungagung Employees. It is an observational analytic study with a cross-sectional approach, involving male bank employees with a marketing position, aged between 27 and 40 years. Data were analyzed and interpreted using the Chi-square test with a nominal variable data scale. The results showed that the asymp. value sig (2-sided) is 0.000, indicating a significant relationship. In conclusion, there is a relationship between stress and Recurrent Aphthous Stomatitis.

ancellous and cortical bone loss in postmenopausal women can be caused by a lack of estrogen, which plays an important role in growth and maturation. The panoramic mandibular index (PMI) also detects loss of bone mass and is a reference for individuals at high risk of developing osteoporosis. Therefore, this study aimed to determine the PMI value in Batak women with postmenopausal conditions using a descriptive survey correlation cross-sectional method. The samples were panoramic radiographs of Batak women with postmenopausal conditions aged >52 years and premenopausal as controls. Furthermore, the data was tested using an Unpaired T-test and the average PMI values in the premenopausal and postmenopausal Batak women groups were 0.327 ± 0.058 and 0.296 ± 0.063, respectively. Statistical analysis indicated a significant difference (p < 0.05, specifically 0.027) in PMI values between the premenopausal and postmenopausal Batak women. These findings showed that PMI served as a reliable indicator of bone loss and potentially aid in identifying individuals at a higher risk of developing osteoporosis.

Oral epithelial dysplasia is an abnormal cytology and architectural change that can develop into oral malignancy with a high mortality rate. Centella asiatica leaves possesses the potential to act as a chemopreventive agent and is known for its relative safety and ease of obtainability. Therefore, this study aimed to determine effect of Centella asiatica leaves extract on dysplasia induced by dimethylbenz [a] anthracene (DMBA) with scratch and incision. The in vivo study involved 21 Wistar rats (Rattus novergicus) divided into three groups. The groups received 2% Centella asiatica leaves methanolic extract orally by force-feeding once daily, from day 1 until day 61. At day 29, dysplasia was induced by scratching the buccal mucosa of each rat using a syringe containing 0.5% DMBA. This was conducted with incision 1 cm in length and half angle in depth, 1 cm in length and 1 mm in depth, and 2 cm in length and 1 mm in depth for groups 1, 2, and 3. Furthermore, the rats were sacrificed, and histopathological analysis was performed using hematoxylin-eosin staining. The degree of dysplasia was assessed using the WHO 2017 classification, and the data were analyzed using the Mann-Whitney test. Meanwhile, the statistical test showed significant difference in the degree of dysplasia for all groups. It can be concluded that Centella asiatica methanolic extract leaves possesses the potential to be a chemopreventive agent in reducing dysplasia levels.
