Research on the Application of KNN Algorithm Incorporating Gaussian Functions in Precision Marketing Classification of E-commerce Platforms
Authors: Wang Guorui 
Published: December 2023

Abstract
The technology can fully explore the user’s consumption behavior habits and help the e-commerce platform formulate more precise marketing strategies in a targeted manner. This paper firstly analyzes the optimization of marketing strategy based on the 3R marketing theory, gives the design process of the precise marketing strategy of an e-commerce platform, and analyzes the personalized service based on consumer classification. Secondly, for the shortcomings of the KNN algorithm in the process of accurate classification, the Gaussian function is introduced to weight the optimization of the algorithm, which further realizes the construction of the G-KNN algorithm. Finally, the testing and application analysis of the algorithm model was carried out using the actual user consumption data of the e-commerce platform. The results show that the classification accuracy of the G-KNN algorithm has been maintained at about 95% when the K value exceeds 800, and the F1 composite value of this paper’s algorithm fluctuates around 56% when the K value exceeds 1000. On the e-commerce platform, except for the electrical appliances category classification test, the fit and accuracy of other categories basically match. Using the KNN algorithm incorporating the Gaussian function can effectively realize the accurate classification of user characteristics on the e-commerce platform and provide data support for the e-commerce platform to formulate accurate marketing strategies based on consumer preferences.

Published: December 2023

AbstractThe energy mix in South-East Europe is nowadays mainly composed by hydro and fossil fuels generation almost equally distributed in the share of electricity generation. Wind and solar PV generation play a very marginal role playing cumulatively less than 7% of the total generation, while fossil fuels exceed 52% of the total generation. A Multi-Terminal HVDC grid between the different countries in South-East Europe may provide various operational and socio-economic gains. In this paper are presented some grid specific challenges and explored some new functions of HVDC transmission systems based on VSC technology that can effectively support the grid with large amount of RES. The paper aims to explore how the VSC converters can improve the system’s voltage stability and provide the necessary frequency control when the inertia in the grid is very low and how the HVDC transmission system can accomplish transferring the primary and secondary reserves solving the rising problems related to dispatchability and inertia response in RES based power grids.
The Structure of Creative Revolutions

Published: December 2023

Abstract
One of the more important questions about creativity is what makes a creative production a revolution? The present contribution follows the analysis of the development of scientific knowledge proposed by Kuhn (1962) in ‘The Structure of Scientific Revolutions,’ to propose a typology that may contribute to an answer. This typology, based on a retrospective analysis of a given domain of productions, distinguishes between two types of creativity: normal creativity and revolutionary creativity. Creative revolutions refer to ‘game changing’ productions in the domain, creating a turning point in the development of this domain. These creative revolutions constitute major disruptions within the domain, since they display both a high degree of novelty and sufficiently high value for future creative productions to take them as a new point of reference. The proposition to distinguish between normal and revolutionary creativity is explored as a complementary view to other typologies on creativity.
Examining the Role of Aesthetic Experiences in Self-Realization and Self-Transcendence: A Thematic Analysis
Authors: Magon Rayan , Cupchik Gerald 
Published: December 2023

Abstract
Numerous scholars, philosophers, and experts in aesthetics have underscored the profound significance of a life enriched by the presence of beauty. Consequently, the appreciation of aesthetic experiences is considered pivotal for achieving self-discovery and self-transcendence (Howell et al. 2017). Despite theoretical prominence, limited qualitative research has been conducted on this topic. To address this gap in research, this study’s objective emphasized two questions guiding the inquiry; What is the role of aesthetic encounters in aiding self-realization or individuation? and, how do these experiences foster self-transcendence?
A thematic analysis was performed on the online interviews conducted (N=25), and their results revealed seven themes pertaining to self-realization: a) Losing Yourself to Find Yourself; b) Relatability and Self-Reflection in Art; c) Identity as a Collection of Skills; d) Art as a Medium for Self-Expression and Acknowledgment; e) Aesthetic Genres and Taste as Identity; f) Belonging and Social Identity through Art; and g) Personal Interests and Choices in Artistic Consumption. Furthermore, seven themes for the second research question of self-transcendence were also discovered: a) Mother Nature’s Beauty; b) Intense, Passionate, and Overwhelming Experiences of Heightened Consciousness; c) Sacred Symbolism, Archetypal Imagery, and the Collective Unconscious; d) Collective Effervescence, Social Connection, and Shared Meaning; e) The ‘Profound’ Found in the Mundane; f) Feelings of Spiritual Elevation and Wellbeing; and g) Self-Referential Meaning-Making through Art. These findings evidenced the transformative potential of aesthetic experiences, shedding light on the facets of personal growth and meaning that individuals derive from such encounters.
Time to remit: the effect of remittances on household consumption and dietary diversity in India
Authors: Sangwan Navjot , Tasciotti Luca 
Published: December 2023

Abstract
India has enjoyed over twenty years of rapid economic growth. The benefits of this growth, however, have largely bypassed India's poor; around a quarter of the world's malnourished children reside in India, and their health poses a significant challenge for the Indian government. Although the growth in India's domestic economy did not result in many trickle-down benefits for the hungry poor, anecdotal evidence suggests that food security related indicators has benefited from another factor. Both rural or urban households have become increasingly reliant on remittances and used them to improve their food security. This paper explores the pattern of relationship between remittances and food consumption/diversity utilising data from the India Human Development Survey collected in 2005 and 2011–12. Using Heckman procedure and the instrumental variable approach to correct for selection and simultaneity bias, the paper finds that remittances increase total food expenditure (mainly the expenditure on protein-rich food such as meats, eggs, pulses, vegetables and fruits) as well as food diversity, measured using the Household Dietary Diversity Score, Shannon and Simpson Index. The results are robust to models’ specification and support the existing evidence that remittances represent a mechanism by which households improve their food security.
Learning English Under the Sounds of Air Raid Sirens: Analysing Undergraduate EFL Students’ Sustainable Learing Practices
Authors: Kapranov Oleksandr , Voloshyna Oksana 
Published: December 2023

AbstractThe article presents a mixed-methods study that examines how undergraduate students of English as a Foreign Language (EFL) sustain their practices of learning English during the ongoing Russo-Ukrainian war in 2022–2023. In total, 33 undergraduate EFL students (henceforth – participants) took part in the study. In order to gain insight into their sustainable learning practices, the participants were requested to write a short reflective essay titled “My Thoughts on How I Learn English during the War”. The participants were instructed to write their essays in English within a one-week timeframe. Seeking to identify and classify a range of sustainable practices related to the ways the participants learnt English during the Russo-Ukrainian war, their reflective essays were analysed qualitatively and quantitatively. The analysis of the participants’ essays revealed the following learning practices that, according to the participants, helped them to sustain their EFL learning trajectory in the wartime EFL contexts: (i) participation in online EFL courses, (ii) communication with the native speakers of English on social networking sites (e.g., Instagram), and (iii) the combination of EFL learning activities offered at the participants’ university. The findings are discussed in detail further in the article through the lens of sustainable multilingualism development. Specifically, we argue that the development of multilingualism in the time of crises is feasible and sustainable, especially if it is coupled with an EFL learner’s inner psychological factors that are further facilitated by the external support offered by the digital learning environments that are (i) institutionalised and systematic, and (ii) extra-mural and unstructured (in other words, digitally wild).

Published: December 2023

Abstract
The article presents the results of analysis of failures of the main functional systems units of aircraft Boeing 737 during the last 10 years of its operation in the national airline of Latvia ‘Air Baltic Corporation’. Total flight time was T∑ = 322,529 h and 184,538 cycles [1]. These data were obtained from daily reports of defects and unplanned consumption of spare parts for these systems. Failures of instrumental equipment of avionic systems were investigated in detail. Based on calculations of their failure probability and component replacement frequency, a comprehensive system including measures and their technical and instrumental support has been developed to improve maintenance productivity. Such a system requires relatively inexpensive components, is simple and can be used in the operation of this type of aircraft.

Published: December 2023

Long climate data information will be very useful for the sustainable agricultural sector in determining physiological processes, growth to plant productivity. The Climate Hazard Group Infrared Precipitation with Station (CHIRPS) data is used as a rainfall database for the latest Oldeman agro-climatic zone mapping in Southeast Sulawesi Province. CHIRPS data for 1981-2021 was processed using the Inverse Distance Weighted and Overlay interpolation methods through the Geographic Information System. The results showed that there were thirteen Oldeman agro-climatic zones in Southeast Sulawesi Province, namely B1 (23,71%), B2 (1,97%), B3 (0,22%), C1 (13,48%), C2 (23,21%), C3 (4,64%), D1 (7,36%), D2 (16,71%), D3 (1,28%), D4 (0,00%), E1 (2,92%), E2 (2,32%), dan E3 (2,18%). Zones B1, B2, and B3 are in the northwest, east, and southeast of the area which are very suitable for cultivating two paddy crops followed by planting various types of secondary crops (palawija) during the dry season. Zones C1, C2, and C3 which stretch from west to east are suitable for one-time planting of paddy and two crops of palawija crops. Zones D1, D2, D3, and D4 are spread from the northwest to the southwest to most areas of Muna Island and Buton Island which are suitable for one short-lived paddy planting and one paddy or palawija crop. The agro-climatic zones E (E1, E2, and E3) in the northwest and southwest are only suitable for one crop of palawija crop, depending on rain. The resulting agro-climate map can be used as a reference for cropping patterns that are suitable for the region of Southeast Sulawesi Province.

PENILAIAN KAPASITAS DAN PEMANFAATAN GAS METANA DI TPA BAGENDUNG CILEGON, INDONESIA
Authors: Hasianetara Sarah , Sodri Ahyahudin , Mugi Astuti Lina Tri 
Published: December 2023

Cilegon only relies on one final disposal site, namely the Bagendung Landfill, which annually receives up to 24.742,80 tons of waste from the population of Cilegon. This amount has an impact on the amount of waste generated and affects the length of time Bagendung Landfill can operate. The process of degradation of organic waste material at the landfill produces landfill gas which includes methane gas (CH4) and carbon dioxide gas (CO2) thereby contributing to GHG (Green House Gas) emissions. This study aims to analyze the remaining operation time frame of and the production of methane gas produced from the waste disposal process at Bagendung Landfill, also its contribution to GHG emissions. This research was started by surveying to find out the waste generation that goes to the landfill and the remaining land area to receive municipal waste. This study used LandGEM version 3.02 software to calculate methane gas production resulting from the landfill waste degradation process. Due to the predicted waste collected in 2024 reaching 281,984.90 m3, Bagendung Landfill can only be utilized until 2024. The emission impact can be reduced by utilizing 1.527.184,57 m3 of methane gas to produce 1.65 GWh as an alternative to electrical energy which is very helpful in meeting the electricity needs of Cilegon City. This research indicates that Bagendung Landfill will not be able to maintain its capacity as it will be reached one year earlier than designed. Utilizing landfill methane gas increases the environment's quality by avoiding 25.471,47 tCO2eq of GHG emissions. Moreover, it can continue after the landfill is closed.

Stereotactic intensity-modulated radiotherapy for skull base meningioma using the HybridArc with Novalis STx system
Authors: Shuto Takashi , Matsunaga Shigeo , Sasame Jo 
Published: December 2023

Background:
Skull base meningiomas are often difficult to remove completely with preserved nerve function and may require radiation therapy. However, the Gamma Knife is unsuitable for large tumor volume or the optic nerve, which is difficult to identify on imaging. We report the results of stereotactic radiotherapy with HybridArc using Novalis STx for skull base meningiomas.

Methods:
We retrospectively examined 28 patients with skull base meningioma who underwent stereotactic radiotherapy (54 Gy/30 fractions) with HybridArc.

Results:
The 28 patients, nine males and 19 females, were aged 31–83 years (mean 58.4 years), and the tumor volume was 2.6–97.1 mL (mean 29.7 mL). HybridArc irradiation was performed with D95 54 Gy/30 fractions for all patients with a median follow-up period of 36.0 months (range: 12–78 months). Tumor control rates at 1, 2, and 5 years after radiotherapy were 92.6%, 89.1%, and 82.8%, respectively. Only one non-atypical meningioma remained uncontrolled; thus, the tumor control rate for non-atypical meningioma at 1, 2, and 5 years was 94.1%. Tumor control rates for atypical meningioma at 1, 2, and 5 years were 85.7%, 71.4%, and 53.6%, respectively, significantly worse than for non-atypical meningiomas (P = 0.0395). Radiation injury was observed in two cases (7.1%). Visual field defects were observed in 16 patients, and diplopia in 6. Visual field and diplopia improvements were achieved in 5 and 2 patients, respectively (with overlap).

Conclusion:
Stereotactic radiotherapy (54 Gy/30 fractions) with HybridArc using Novalis STx is a safe and effective approach for relatively large skull base meningiomas.
