Authors: Mokshin Pavel V. , Golovashkin Dimitriy L. , Pavelyev Vladimir S.
Published: October 2024

Background. An approach to the design of photonic crystal (PhC) devices is proposed, which differs from the known general-purpose optimization methods (for example, a genetic algorithm or gradient procedures) by using information about diffraction patterns at different frequencies when optimizing an element designed to operate at the selected wavelength. The following is an approach to the design of photonic crystal elements. The proposed approach differs from known general-purpose optimization methods (e.g., genetic algorithm or gradient procedures) by using diffraction pattern information at different frequencies while optimizing an element designed to operate at the selected wavelength. The design of functional PhC structures with expected characteristics (for example, waveguides) for a certain wavelength (albeit given by a monochromatic radiation source) is described. Aim. Development based on the FDTD method and confirmation of the functionality of the iterative procedure for calculating the characteristics of metal-dielectric PhC lattices. Methods. The study is based on an iterative approach to the design of PhC elements based on the use of the FDTD method. Results. Model examples were used for demonstration of practical convergence and applicability of the developed iterative procedure. The efficiency of the PhC waveguide, understood as the ratio of the output energy to the input energy, was increasing at each iteration up to 97.2%. Conclusion. The method of synthesis of metal-dielectric PhC structures with preset properties based on application of developed iterative procedure is proposed and argued. The results of the analysis of the 2D PhC waveguide based on a set of round copper rods show the applicability of the proposed method.

Background. For further development of communication networks, it is planned to use hybrid satellite networks for traffic transmission. However, satellite communication channels have features such as distortion caused by the Doppler effect and increased energy efficiency requirements. Aim of this study is to analyze variants of orthogonal frequency multiplexing methods and modulation methods in order to choose the most stable technology, taking into account destabilizing factors. Method. Comparing different signal processing technologies and studying their resistance to bit errors is the imitation modeling of the communication channel in the Matlab environment. This approach allows creating a model of the communication network, taking into account the main parameters of communication channels, such as the Doppler effect, energy deficiency and destabilizing factors. Results. The distribution of the bit error coefficient for various signal processing technologies, depending on the signal-to-noise ratio, is compared. The method of frequency multiplexing is defined, providing the minimum peak factor and the most resistant to bit error. It is also noted that the effectiveness of all the studied technologies depends on the spacing and modulation constellations, and that it is necessary to adjust the characteristics of the system for each case. Conclusion. The results of this study can be used to improve the quality of communication in difficult interference conditions of hybrid mobile networks of 5 and 6 generations using the satellite segment.

Research of salt tolerance mechanism of sandy shrub Tamarix spp
Authors: Liu Hongxia
Published: October 2024

6.5% of the world's total land area is saline-alkali land, and more than 800 million hectares of saline soil are distributed worldwide. Soil salinization has become an important constraint on global food security and ecological security. Tamarix is a typical salt-secreting halophyte, which can excrete the salt in the plant from the body. The use of plant resources to transform saline-alkali soils has fundamentally alleviated soil salinization compared with traditional methods. Therefore, the research on the salt tolerance mechanism of tamarisk is very important to alleviate the problem of the shortage of cultivated land resources.

Not Easy Being “Me”: Deconstructing Foreign Language Teachers’ Self Through Collaborative Autoethnography
Authors: Hernández Victoria Juan Camilo , Diaz González Laura Daniela , Méndez Garzón Franz Stehf
Published: October 2024

In this article, we, three pre-service Foreign Language teachers, used an introspective view of our memories and experiences to extract relevant aspects that defined our teacher self, teaching methodology, and vocation in Southern Colombia. We used a collaborative autoethnographic approach with virtual cumulative collaboration and an analytical/evocative typology. Our stories are evocative, but our experiences were extracted using instruments such as memory collection, self-reflections, reflective journal writing, autobiographical essays, and focus group discussions. We found tacit structural/sociological policies and factors which influenced our learning processes throughout our student selves. Factors concerning acculturation/cultural integration, affective teaching environments or lack thereof, and family dynamics influenced our selves. From retelling our stories, we can see that these policies/factors had an adverse effect in our learning, but a positive effect on our teacher selves and vocation. We can safely say that negative learning/family experiences influencedour teacher selves for the better in our stories.

Authors: Wei Wenzhe
Published: October 2024

INTRODUCTION. The relevance of the study is related to the study of the features of the implementation of tourist advertising in such a dynamically developing real segment as religion. The role of tourist advertising is increasing, and it is becoming especially important to study specific pragmatic oriented language units devoted to religious discourse. The purpose of the study is to identify lexical, morphological units and stylistic devices used in tourist religious discourse.

MATERIALS AND METHODS. The research material was advertising texts promoting religious tours on the Internet. The collection and writing of factual material was carried out using conceptual analysis, interpretive analysis was used to determine and explain the linguistic features of religious advertising text.

RESULTS AND DISCUSSION. The appeal to advertising texts promoting religious tours allowed to identify pragmatically oriented linguistic units. Religious discourse, oriented towards introducing a person to faith within the framework of a certain confession, contributes to the implementation of religious tours (pilgrimage, educational and pilgrimageeducational). Religious advertising discourse in the field of tourism can be oriented towards the discourses of consumer society, but at the same time give them new, religious and sacred outlines.

CONCLUSION. The identified lexical units and stylistic means in tourist advertisements on the topic of religious tours allow us to consider that religious tourist advertisement has a number of characteristics inherent only to it and occupies its own special place among currently existing types of discourse. These advertisements can be considered special speech patterns of text aimed at implementing the pragmatic function of advertising messages.

Changes in care provision to older parents during COVID-19 and the well-being of adult children: The moderating roles of the child-parent relationship and pandemic-related measures
Authors: Cohen Liora , Shiovitz-Ezra Sharon , Cohen Avi
Published: October 2024

Objective: The study addresses the associations between changes in care provision to older parents since the pandemic and worsened depression and anxiety in adult children. It also explores whether pandemic-related control measures and child-parent relationships moderated these associations.
Background: Changes in informal care during the pandemic, such as increased or decreased caregiving frequency, may have affected caregivers’ psychological well-being. Limited research exists on how stressors and resources shape the well-being of adult children caregivers.
Method: Data from 740 respondents in the first SHARE Corona Survey (SCS) who provided care for their parents during the pandemic were analyzed. Changes in depression and anxiety were assessed using data from SCS and pre-pandemic Wave. Logistic regression analyses were conducted, with added interactions between the moderators - pandemic measures and child-parent relationship characteristics - and changes in care frequency.
Results: Increased caregiving frequency during the pandemic was associated with worsened depression. Stricter pandemic measures intensified this effect but also reduced the likelihood of anxiety for those who provided care less often. A higher quality of relationship with the mother in childhood was marginally associated with lower depression among those increasing caregiving but worsened depression for those decreasing it.
Conclusion: To address post-pandemic caregiving challenges, efforts should focus on reducing caregiver stress and considering the enduring influence of early child-parent relationships.
Split Payment as a Method of Consumer Payment in Online Buying and Selling Practices Is Reviewed From the Principle of Legal Certainty
Authors: Wahyuni Sri
Published: October 2024

Current technological advances have led to the development of payment methods in online buying and selling practices. Usually the payment method is made via cash and non-cash; one of the current payment methods is known as the split payment method. Split payment is a payment made using more than one payment method to complete the entire transaction. There is a case where a consumer buys goods online by paying using split payment and the consumer will be given cash back when using split payment. However, the goods that have been purchased do not reach the consumer. The consumer and the shop agreed to ask for compensation from the market place, which is a meeting place for online buyers and sellers. Based on this case, the author is interested in researching the problem of how to complete online buying and selling transactions using split payments. This research uses normative legal research methods with a statutory approach. The results of this research show that it is important to have special regulations regarding the definition and validity of split payment methods for online buying and selling transactions in order to provide guarantees, justice and consumer security in order to realize the principle of legal certainty.

Published: October 2024

The importance of the bank in applying the precautionary principle contributes to ensuring a sound banking system and protecting the country’s economy. In lending, the precautionary principle was manifested in a standard agreement between the bank as the creditor and the customer as the debtor. Credit agreements can lead to disputes, where the debtor sues the bank for violating the principle of consumer protection because it applies standard clauses in the credit agreement. The research method used is legal research with a statute approach and a conceptual approach). The results state that the application of the precautionary principle in making standard agreements manifests itself in the prohibition of financial service business actors including exoneration clauses to the detriment of financial service consumers as stipulated in Article 18 paragraph (1) of the Consumer Protection Act and OJK Regulation No. 6/POJK.07/Tahun 2022 concerning Consumer and Community Protection in the Financial Services Sector.

Published: October 2024

Addicts or users of narcotics are both victims and criminal perpetrators of crimes. All narcotics abusers utilizing criminal provisions are governed by the Article 127 of Law No. 35 of 2009 pertaining to narcotics According to Article 127, those who abuse drugs face jail time, while those who are addicted to drugs or who have been abused by them are sent to facilities for social and medical rehabilitation. However, it is often found that addicts experience a relapse after carrying out medical and social rehabilitation. When it comes to keeping drugs users from relapsing, religious rehabilitation is superior to medical and social rehabilitation. This study was carried out with a sociological juridical methodology. Purposive nonrandom sampling was the method employed for sampling. The data collection was carried out by library and field studies (through observation, questionnaires and interviews) of the authors and book users. Data analysis was performed using qualitative descriptive analysis. There is a gap in the motivation to resume drug use to shortcomings in medical and social recovery. Additionally, treating addicts with a religious approach that touches their hearts makes them less likely to hesitate to take drugs in the future.

Authors: Ferrini Silvia , Pampaloni Filippo , Delogu Francesco , Goffetti Giulia , Viti Cecilia , Capitani Giancarlo
Published: October 2024

Asbestos-containing waste presents a multifaceted challenge to governments and society, demanding innovative solutions. This article unveils options to manage asbestos-containing waste and analyze merits and drawbacks of thermal inertization technology, focusing on a newer patent which reduces the treatment time (and costs) and yields a reusable, asbestos-neutral building material. Impact assessment requires the formal valuation of a new project, technology, or program. In this article, we present a mixed-method approach (life cycle analysis with an extended cost–benefit analysis) and provide insights into the financial, economic, and environmental dimensions of asbestos-containing waste. The results suggest that inertization technologies hold the promise of a sustainable alternative to deep landfill burial. However, their success is contingent on securing public funding, a thorough examination of hidden environmental costs and risks, and the establishment of supportive regulations fostering a circular economy. These findings underscore the imperative for further exploration and substantial financial commitments to make asbestos treatment options a global reality.

Artikel ini bertujuan mendiskusikan kearifan lokal, khususnya tradisi kawin lari, yang terefleksi di dalam karya sastra. Penelitian menggunakan metode kualitatif dengan analisis deskriptif. Objek materialnya adalah novel Mangalua karya Idris Pasaribu, sedangkan objek formal berupa teori antropologi sastra dan teori representasi. Hasil kajian menunjukkan kuatnya nilai-nilai lokalitas dan dinamika peradaban. Hal tersebut merepresentasikan religi berupa aliran kepercayaan (Parmalim), agama samawi (Kristen), kearifan lokal berupa tradisi kawin lari (mangalua), dan refleksi multivalensi budaya. Dari berbagai tanda (bahasa dan warna lokal) dan konsep (dalam pikiran pengarang dan pembaca) tentang kawin lari, maka dapat dimaknai bahwa novel Mangalua merepresentasikan kisah kehidupan masyarakat Batak Toba masa lalu (masa kolonial Belanda), baik menyangkut religi maupun kearifan lokal. Dari perspektif budaya (antropologi), tradisi kawin lari mengandung nilai positif karena mampu mengakomodasi nilai-nilai kemanusiaan dalam menyelesaikan persoalan yang dialami oleh masyarakat di tanah Batak. Tradisi kawin lari menjadi alternatif solusi secara kultural yang bersifat fleksibel dan humanis.
Rusli dan Nashar, Dua Maestro Pelukis Abstrak IKJ: Sistem Tanda Sosial Budaya
Authors: Sungkar Anna
Published: October 2024

Artikel ini membahas tentang dua pelukis Jakarta: Rusli dan Nashar yang bersama-sama berjuang untuk kemerdekaan Indonesia melalui organisasi SIM di Madiun dan Yogyakarta. Setelah perang usai, mereka menciptakan karya-karya modernisme bergaya abstrak yang jauh berbeda dengan ideologi SIM yang beraliran realisme. Mereka kemudian membangun LPKJ di Jakarta, sebuah sekolah seni non konvensional yang mengutamakan kebebasan berekspresi, penghayatan atas alam, studi luar ruang dan lintas disiplin ilmu. Penelitian ini menggunakan metode deskriptif melalui teknik observasi dengan beberapa studi kasus, yaitu menelaah gaya lukisan mereka dan menemukan kesamaan karakteristik dari karya-karyanya. Ternyata mereka mempunyai benang merah, yaitu kecintaan dan penghayatan atas alam demi mendapatkan esensinya. Pemikiran mereka itu kemudian diteruskan kepada para mahasiswa LPKJ (dan kemudian namanya diubah menjadi IKJ) serta menginspirasi generasi seniman Indonesia yang lebih muda.
