Authors: Rahayu Gusti , Nirwana Herman , Netrawati Netrawati
Published: December 2021

This study aims to analyze the identity of high school students based on four levels of status (identity diffusion, identity foreclosure, identity moratorium, and identity achievement). Self-identity is very important because the task of development at that time is to adapt to changes that exist in oneself. Teens who experience an identity crisis show that they are trying to find their identity. Therefore, adolescents need help to improve their identity. This study aims to describe the identity of students. The sample in this study consisted of 240 high school students who were selected by proportional random sampling. The instrument used was a self-identity scale. The instrument used has been tested for validity and reliability. Data analysis in this study used a quantitative approach with descriptive methods. The results showed that identity diffusion was in the high category 33.85 (81 students), identity foreclosure was in the high category 10.8% (26 students), identity moratorium was in the high category 46.2% (111 students), and identity achievement was at high category 9.3% (22 students). The implication of this research is the counselor's basis for improving the self-identity of students in schools

Published: December 2021

The life of the Indonesian people is a very complex life with various social problems that hit several communities. The existence of various social problems faced by the community makes them live an abnormal or inappropriate life such as the low economy in meeting the needs of life. Social problems are some conditions that arise from a society that cannot function properly, resulting in disappointment and suffering. In this case, those who often experience social problems are usually women, one of the people with social welfare problems, namely Commercial Sex Workers. Someone who works and acts in the field of prostitution is better known as a commercial sex worker. The practice of prostitution by sex workers causes several psychological impacts that refer to negative self-concepts, such as feeling of having low self-esteem in the eyes of the community, being inferior in front of many people, limiting themselves in community interactions, feeling depressed, relationship gaps with other family members. Based on the results of the study, there were 8 PSKs whose self-concept level was in the medium category with a percentage of 38.1%, then 10 PSKs whose self-concept level was in the low category, namely 47.6%. 2 PSKs whose self-concept level was in the very low category, namely 9.5%. So it can be concluded that the average self-concept of CSWs before being given treatment was in the medium and low categories. The research method used by the researcher is the experimental research method. The type of experimental research used by the researcher is a quasi-experimental (quasi-experimental). Quasi-experimental is a quasi-experiment that aims to predict the conditions that can be achieved through actual experiments, but there is no control and manipulation of all relevant variables. Based on the description above, it can be concluded that this study seeks to determine how high the self-concept of sex workers is

Published: December 2021

Nonparametric kernel estimators are mostly used in a variety of statistical research fields. Nadaraya-Watson kernel estimator (NWK) is one of the most important nonparametric kernel estimator that is often used in regression models with a fixed bandwidth. In this article, we consider the four new Proposed Adaptive Nadaraya-Watson Kernel Regression Estimators (Interquartile Range, Standard Deviation, Mean Absolute Devotion, and Median Absolute Deviation) rather than (Fixed Bandwidth, Adaptive Geometric, Adaptive Mean, Adaptive Range, and Adaptive Median). The outcomes in both simulation and actual data in Leukemia Cancer show that the four new ANW Kernel Estimators (Interquartile Range, Standard Deviation, Mean Absolute devotion, and Median Absolute Deviation) is more effective than the kernel estimations with fixed bandwidth in previous studies using Mean Square Error (MSE) Criterion.

Authors: Nabillah Ratu
Published: December 2021

The dichotomy of "village" and "city" that often occurs in development practice requires attention to the relationship between villages and cities. This linkage can be seen in the transitional area between rural and urban areas. The transition area is a small-town. A large number of small cities in Indonesia and the significant function of the existence of small towns make the development of small towns need attention. This study aims to analyze the perceptions of the younger generation on the development of small towns in Kalianda District, South Lampung Regency, and to analyze the relationship between the identity of the young generation against various indicators of small-town development. The variables in this study are divided into the economy, education, transportation, tourism, and other developments where there are various indicators of small-town development. Percentage Analysis and Chi-Square Analysis were used in the study. This study indicates that overall the younger generation has different views on the development of small towns, but 10 out of 16 indicators are considered to be in good development (stage 2). There are only three identities of respondents who have no relationship to small – town development: gender – tourism development, social media – market development, social media – tertiary employment development.

Published: December 2021

Over the years, population surges resulted in urban sprawl in meeting the needs and demands of the future generation. However, excessive human activities in the environment cause environmental degradation, which affects cities resilience. In addition,  the impact of global climate change has significantly affected the local environmental context in many towns. As a result, we experience constant incidences of natural disasters, such as monsoon floods, flash floods and landslides. The absence of a framework to address the resilience level in Selangor may lead to a problematic situation in planning and managing the development concerning the physical contexts, for instance, the location and topographic aspects. Therefore, this paper introduces the research to develop an Environmental Resilience Index (ERI) to measure Malaysia's level of environmental resilience by selecting Selangor as a case study because of the difference in economic activities that could result in different levels of environmental resilience. This paper also explains the general framework and indicator selected for this study by reviewing environmental systems and reviews of past research and established indicators. Though this study uses secondary data as the basis of data collection, data from authorised departments and agencies are gathered to verify the reliability and validity of data essential in the analysis stage. Lastly, this paper elaborates on the methodology of data collection and data analysis with an example by measuring the ERI level for the component of environmental resources for the district of Kuala Selangor. Considering the latest secondary data, the results demonstrate that Selangor has an ERI of moderate level for the component of environmental resources.

Abstrakt

Mikrobiota jelitowa stanowi nieodłączny element organizmu umożliwiający jego prawidłowe funkcjonowanie. Dzięki mikroorganizmom jelitowym możliwa jest stymulacja układu odpornościowego, synteza witamin czy poprawa wchłaniania składników odżywczych. Jednak jej aktywność może również niekorzystnie działać na organizm, m.in. z powodu przetwarzania treści jelitowej. Opisywana w artykule interakcja mikrobiota–lek uwzględnia pozytywny i negatywny wpływ mikroorganizmów jelitowych na farmakoterapię poprzez bezpośrednie i pośrednie oddziaływanie na lek w organizmie. Ze względu na to, że mikrobiom stanowi nieodłączny element organizmu, ingerencja nawet w jego niewielką część może doprowadzić do wystąpienia daleko idących, czasami niespodziewanych skutków. Stąd w celu poprawy skuteczności i bezpieczeństwa farmakoterapii konieczne jest wyjaśnienie mechanizmów oddziaływania mikrobioty na lek w organizmie.

W artykule podsumowano obecną wiedzę na temat biologicznej aktywności mikrobioty jelitowej, a zwłaszcza oddziaływań mikrobiota–leki determinujących skuteczność i bezpieczeństwo farmakoterapii. Wyszukiwanie przeprowadzono we wrześniu 2020 r. w bazach danych PubMed, Scopus, Web of Science, Cochrane Library i powszechnie dostępnej literaturze z użyciem terminów: „mikrobiota jelitowa”, „mikrobiom”, „metabolizm leku”, „interakcje mikrobiota–lek”. W artykule omówiono interakcje między mikrobiotą a lekami m.in. z grupy antybiotyków, inhibitorów pompy protonowej, sulfonamidów, pochodnych kwasu 5-aminosalicylowego, niesteroidowych leków przeciwzapalnych, przeciwnowotworowych, statyn czy metforminą.

Abstrakt

Background

Diabetes and periodontitis belong to the group of civilizational diseases, which are not associated with any specific bacterial or viral infection but with the rapid development of civilization and technological advances that affect comfort and quality of life. Civilizational diseases occur in highly developed and developing societies. Glycosylated hemoglobin A1c (HbA1c) is one of the standard indicators for the assessment of metabolic compensation in diabetes that reflects the risk of disease complications. One of the significant complications of diabetes that manifests in the oral cavity is gingival and periodontal inflammation, which is directly related to increased insulin resistance and worsened diabetes compensation. Factors influencing inflammation are the patient’s age, directly linked with fine motor skills when it comes to cleaning teeth, and patients’ awareness related to cause-and-effect relationship between dental hygiene, gingival and periodontal inflammation, and HbA1c testing during routine check-ups.

Objectives

To compare the relationship between gingival inflammation and metabolic compensation (HbA1c levels), depending on the patient’s age.

Materials and methods

The study involved 100 patients (50 adolescents and 50 adults, 42 M; 58 F) with type 1 diabetes. The study group was divided according to sex and age into 19 male adolescent patients (10–18 years old; mean age 15.5) and 23 male adult patients (19–45 years old; mean age 27.1). The mean duration of diabetes was 7 years in the group of adolescents and 11 years in the group of adults. The HbA1c levels and gingival index (GI) were measured in all patients. The obtained results were statistically analyzed.

Results

By comparing the study groups, higher HbA1c values were reported in the group of adolescents. HbA1c has been shown to correlate with the GI in adolescents and adults. Despite poorer compensation for diabetes (higher HbA1c), GI values were similar in adolescents and adults.

Published: December 2021

Intrusion Detection Systems (IDSs) utilise deep learning techniques to identify intrusions with maximum accuracy and reduce false alarm rates. The feature extraction is also automated in these techniques. In this paper, an ensemble of different Deep Neural Network (DNN) models like MultiLayer Perceptron (MLP), BackPropagation Network (BPN) and Long Short Term Memory (LSTM) are stacked to build a robust anomaly detection model. The performance of the ensemble model is analysed on different datasets, namely UNSW-NB15 and a campus generated dataset named VIT_SPARC20. Other types of traffic, namely unencrypted normal traffic, normal encrypted traffic, encrypted and unencrypted malicious traffic, are captured in the VIT_SPARC20 dataset. Encrypted normal and malicious traffic of VIT_SPARC20 is categorised by the deep learning models without decrypting its contents, thus preserving the confidentiality and integrity of the data transmitted. XGBoost integrates the results of each deep learning model to achieve higher accuracy. From experimental analysis, it is inferred that UNSW_ NB results in a maximal accuracy of 99.5%. The performance of VIT_SPARC20 in terms of accuracy, precision and recall are 99.4%. 98% and 97%, respectively.

Published: December 2021

Fish diversity of a riverine ecosystem became reduced due to different manmade and natural calamities. This study investigated the present fish biodiversity status of the Dharla River located (25.8103° N, 89.6487° E) in the northern part of Bangladesh from January to December 2018. In this study, the existing fish biodiversity status of the Dharla River was estimated in terms of diversity indices and threatened status (both global and local). Data was collected from the three sampling sites of the river using different fishing gears and three selected fish markets located in the Kurigram district of Bangladesh. A total of 76 fish species were identified belonging to 8 orders, 26 families and 57 genera. The Cyprinidae was the most dominant family represented by 14 species followed by the Danionidae (13 species), Bagridae (8 species) and few minor families. Apart from the indigenous species, nine exotic fish species were also recorded. The Shannon-Weaver diversity (H), Pielous evenness (e) and Margalef richness (D) indices ranged from 3.00 to 3.71, 0.62 to 0.94 and 3.94 to 7.95, respectively. Out of 76 indigenous species, 28 species (37%) were identified as threatened in Bangladesh, which included critically endangered (4), vulnerable (9) and endangered (15) species. Indiscriminate fishing through poisoning and destructive fishing gears were identified as the major threats to fish biodiversity of the Dharla River. Thus, the river serves as considerable support for threatened indigenous fishes. Therefore, necessary steps are needed to stop destructive fishing, establish permanent fish sanctuaries and proper monitoring for maintaining sustainable biodiversity in the Dharla River.
The Limits of Leadership as a Barrier to Quality Assurance in Higher Education in Algeria
Authors: Belimane Wissam , Chahed Amina
Published: December 2021

Since 2010, Quality Assurance (QA) has been officially adopted and has become a priority of the Higher Education (HE) system in Algeria. This study is part of this framework and aims to explore the role of leadership in the QA process as perceived by Quality Management Managers (QMRs). It is based on a qualitative approach through interviews with 27 QMRs from different institutions. Content analysis technique was used to analyse data.

The results show that QMRs consider the lack of commitment and involvement of institutions’ higher management as a major constraint to the success of quality processes. The study reveals that the main barrier to QA is related to the limitations of institutions’ governance, which do not promote autonomy and effectiveness. The study suggests that two elements seem to be crucial: autonomy andtraining/awarenessof institutions’ higher managers. Those elements are closely linked and could be at the origin of the success or failure of quality mechanisms.
Gene expression levels of DNA methyltransferase enzymes in Shank3-deficient mouse model of autism during early development
Authors: Srancikova Annamaria , Reichova Alexandra , Bacova Zuzana , Bakos Jan
Published: December 2021

Objectives. The balance between DNA methylation and demethylation is crucial for the brain development. Therefore, alterations in the expression of enzymes controlling DNA methylation patterns may contribute to the etiology of neurodevelopmental disorders, including autism. SH3 and multiple ankyrin repeat domains 3 (Shank3)-deficient mice are commonly used as a well-characterized transgenic model to investigate the molecular mechanisms of autistic symptoms. DNA methyltransferases (DNMTs), which modulate several cellular processes in neurodevelopment, are implicated in the pathophysiology of autism. In this study, we aimed to describe the gene expression changes of major Dnmts in the brain of Shank3-deficient mice during early development.

Methods and Results. The Dnmts gene expression was analyzed by qPCR in 5-day-old homo-zygous Shank3-deficient mice. We found significantly lower Dnmt1 and Dnmt3b gene expression levels in the frontal cortex. However, no such changes were observed in the hippocampus. However, significant increase was observed in the expression of Dnmt3a and Dnmt3b genes in the hypothalamus of Shank3-deficient mice.

Conclusions. The present data indicate that abnormalities in the Shank3 gene are accompanied by an altered expression of DNA methylation enzymes in the early brain development stages, therefore, specific epigenetic control mechanisms in autism-relevant models should be more extensively investigated.

Published: December 2021

This work is dedicated to the study of the succession processes in quarries of different ages in the territory of the Russian Federation and neighbouring countries, namely, Kazakhstan and Ukraine. In selected soil samples from the areas studied, certain physical and chemical properties, the quantitative composition of microbial communities and the diversity of floral species from the quarries were studied. The pH values for the Kuzbass area were found to decrease to 4.8, and in the area of the younger quarries – Inguletsky and Sokolovsky – higher pH values were recorded. The basal soil respiration rate of the Kuzbass quarry was approximately 0.2 mg CO2/g/h. The CO2 carbonate content ranged from 0.05% to 0.6%. The microbial biomass in Kuzbass soil was from 0.87 to 5.10 μg C/g soil, while its quantity in other quarries was 6 times lower, which is associated with the relatively young age of these sites. The study of the diversity of floral species in the Kuznetsk coalfield identified 120 species of upper plants belonging to 34 families. Among them, cereals, legumes and mosses, lichens and algae were predominant. In the territory of Inguletsky and Sokolovsky quarries, the diversity of plant species was much poorer. In this regard, further research will focus on increasing the rate of succession and maintaining ecosystem stability by increasing the share of microorganisms. Also, the study of the possibility to accelerate the restoration of younger flora in the discharges of age careers at the expense of the mycorrhizal communities formation is of high relevance.

This work presents a mathematical model of an aeropendulum system with two sets of motors with propellers and the design and simulation of a loop-shaping ℋ∞ control for this system. In this plant, the objective is to control the angular position of the pendulum rod through the torque generated by the thrust of the motorized propellers at the end of the rod’s axis. The control design is obtained by first using feedback linearization and then designing the ℋ∞ controller using the resulting linear system. For the control strategy validation, simulations were conducted in the Matlab/Simulink® environment, and the weighting functions for the ℋ∞ controller were adjusted to obtain the desired performance and stability of the closed-loop system. The simulation results show the efficiency of the applied methodology.

Published: December 2021

In the article, the analytical dependences of modelling the cell cross-sectional area between two adjacent blades of a rotary blade pump and capacity for a pump with fixed and rotating stators are given, and analytical dependences are derived to model the power necessary to overcome the friction forces of the blades. The forces acting on the radially placed blade of a rotary pump with a fixed stator (non-rotating or stationary) and a rotating stator are analyzed. Design and technological parameters that influence the pump capacity and power are taken into account. The power required for the movement of the pump blade without taking into account the compression of the air has the opposite character of the change as to the pump capacity The capacity of a rotary pump with a rotating stator is three times higher than that of a stationary stator. The rotary pump with a rotating stator, with six radially spaced blades, consumes 0.854 [kW] less power to overcome the blade friction of 1 313 [kW]. The results of modelling of the pump work are given.
Effects of Rotation on Transient Fluid Flow and Heat Transfer Through a Curved Square Duct: The Case of Negative Rotation

Published: December 2021

The fluid flow and heat transfer through a rotating curved duct has received much attention in recent years because of vast applications in mechanical devices. It is noticed that there occur two different types of rotations in a rotating curved duct such as positive and negative rotation. The positive rotation through the curved duct is widely investigated while the investigation on the negative rotation is rarely available. The paper investigates the influence of negative rotation for a wide range of Taylor number (−10 ≤ Tr ≤ −2500) when the duct itself rotates about the center of curvature. Due to the rotation, three types of forces including Coriolis, centrifugal, and buoyancy forces are generated. The study focuses and explains the combined effect of these forces on the fluid flow in details. First, the linear stability of the steady solution is performed. An unsteady solution is then obtained by time-evolution calculation and flow transition is determined by calculating phase space and power spectrum. When Tr is raised in the negative direction, the flow behavior shows different flow instabilities including steady-state, periodic, multi-periodic, and chaotic oscillations. Furthermore, the pattern variations of axial and secondary flow velocity and isotherms are obtained, and it is found that there is a strong interaction between the flow velocities and the isotherms. Then temperature gradients are calculated which show that the fluid mixing and the acts of secondary flow have a strong influence on heat transfer in the fluid. Diagrams of unsteady flow and vortex structure are further sketched and precisely elucidate the curvature effects on unsteady fluid flow. Finally, a comparison between the numerical and experimental data is discussed which demonstrates that both data coincide with each other.

Published: December 2021

The current study aims to investigate the effects of swell pressure on the bearing capacity of swelling soil. A model and some laboratory tests have been created to investigate the swell pressure effect on the bearing capacity variation of soil swelling due to swelling pressure. The influence of varying water content w/c and dry unit weight (γd) on the shear strength and swelling pressure was studied. The soil has been taken from Diwan Residential Compound-Mosul. It is classified as highly swelling soil. The swell pressure of soils at their natural water content reached 385 kN / m2. Experiment results show that the parameters of shear resistance decreased with the w/c increase at the constant value of (γd), increased with the (γd) increase when the w/c was constant. Results show that the swelling pressure decreased with the w/c increase, while it increased with the (γd) increase. Also, the results obtained using was model show that the resistance of bearing capacity of pre-saturated selected soil was 196 kN / m2, while the bearing capacity was 620kN / m2 when taking into account in the generation of swelling pressure.
Review on Relationship Between the Universality Class of the Kardar-Parisi-Zhang Equation and the Ballistic Deposition Model
Authors: Sayfidinov Okhunjon , Bognar Gabriella
Published: December 2021

We have analysed the research findings on the universality class and discussed the connection between the Kardar-Parisi-Zhang (KPZ) universality class and the ballistic deposition model in microscopic rules. In one dimension and 1+1 dimensions deviations are not important in the presence of noise. At the same time, they are very relevant for higher dimensions or deterministic evolution. Mostly, in the analyses a correction scale higher than 1280 has not been studied yet. Therefore, the growth of the interface for finite system size β ≥ 0.30 value predicted by the KPZ universality class is still predominant. Also, values of α ≥ 0.40, β ≥ 0.30, and z ≥ 1.16 obtained from literature are consistent with the expected KPZ values of α = 1/2, β = 1/3, and z = 3/2. A connection between the ballistic deposition and the KPZ equation through the limiting procedure and by applying the perturbation method was also presented.

Published: December 2021

By designing road infrastructure, it is necessary to adapt the real situation to current development trends and respond accordingly to the intensity of traffic on the transport network. The development of the traffic situation is generally very dynamic, difficult to predict and influenced by a number of other factors. Modern technologies enable adaptive traffic flow management based on the sharing and evaluation of traffic information obtained in real time from traffic monitoring systems or even from vehicles as such (e.g. thanks to “Connected Vehicles” technology). The article first carries out a literature review of professional literature and scientific articles dealing with the issue of autonomous mobility and autonomous management of transport processes. That is followed by a description and creation of own algorithm for autonomous control of vehicles at the level crossing, including description of used data, methods and proposed solutions. Finally, the developed method (algorithm) is tested by the Anylogic simulation program in a real environment, as a case study of autonomous vehicle decision-making at the level crossing.
