Authors: Pérez-Pons María E. , Parra-Dominguez Javier , Omatu Sigeru , Herrera-Viedma Enrique , Corchado Juan Manuel 
Published: February 2022

Abstract

Context: Machine Learning (ML) is a disruptive concept that has given rise to and generated interest in different applications in many fields of study. The purpose of Machine Learning is to solve real-life problems by automatically learning and improving from experience without being explicitly programmed for a specific problem, but for a generic type of problem. This article approaches the different applications of ML in a series of econometric methods.

Objective: The objective of this research is to identify the latest applications and do a comparative study of the performance of econometric and ML models. The study aimed to find empirical evidence for the performance of ML algorithms being superior to traditional econometric models. The Methodology of systematic mapping of literature has been followed to carry out this research, according to the guidelines established by [39], and [58] that facilitate the identification of studies published about this subject.

Results: The results show, that in most cases ML outperforms econometric models, while in other cases the best performance has been achieved by combining traditional methods and ML applications.

Conclusion: inclusion and exclusions criteria have been applied and 52 articles closely related articles have been reviewed. The conclusion drawn from this research is that it is a field that is growing, which is something that is well known nowadays and that there is no certainty as to the performance of ML being always superior to that of econometric models.
Handling Realistic Noise in Multi-Agent Systems with Self-Supervised Learning and Curiosity
Authors: Szemenyei Márton , Reizinger Patrik 
Published: February 2022

Abstract

1Most reinforcement learning benchmarks – especially in multi-agent tasks – do not go beyond observations with simple noise; nonetheless, real scenarios induce more elaborate vision pipeline failures: false sightings, misclassifications or occlusion. In this work, we propose a lightweight, 2D environment for robot soccer and autonomous driving that can emulate the above discrepancies. Besides establishing a benchmark for accessible multi-agent reinforcement learning research, our work addresses the challenges the simulator imposes. For handling realistic noise, we use self-supervised learning to enhance scene reconstruction and extend curiosity-driven learning to model longer horizons. Our extensive experiments show that the proposed methods achieve state-of-the-art performance, compared against actor-critic methods, ICM, and PPO.

Abstract

Background
The efficacy of first-line chemoradiotherapy for overall survival (OS) might be confounded by the subsequent treatments in patients with locally advanced non-small cell lung cancer (NSCLC). In this study, we assessed the associations of progression-free survival (PFS) and post-progression survival (PPS) with OS after chemoradiotherapy for locally advanced NSCLC using patient-level data.

Patients and methods
Between January 2011 and December 2018, 45 patients with locally advanced NSCLC who had received first-line chemoradiotherapy and in whom recurrence occurred were analysed. The associations of PFS and PPS with OS were analysed at the individual level.

Results
Linear regression and Spearman rank correlation analyses revealed that PPS was strongly correlated with OS (r = 0.72, p < 0.05, R2 = 0.54), whereas PFS was moderately correlated with OS (r = 0.58, p < 0.05, R
2 = 0.34). The Glasgow prognostic score and liver metastases at recurrence were significantly associated with PPS (p < 0.001).

Conclusions
The current analysis of individual-level data of patients treated with first-line chemoradiotherapy implied that PPS had a higher impact on OS than PFS in patients with locally advanced NSCLC. Additionally, current perceptions indicate that treatment beyond progression after first-line chemoradiotherapy might strongly affect OS.
Familial Terminology and the Progressive Nature of Church Membership in Cyril of Jerusalem
Authors: Huovinen Harri 
Published: February 2022

Abstract
There is too little study of Cyril of Jerusalem’s notion of the ecclesiological identity of baptismal candidates. I found that his use of familial terminology was not simply limited to that of the Biblical and Patristic models, i.e., fully initiated members of the church. He applied it to unbaptized candidates as well. They shared in a primal yet real membership of the ecclesial family. They were progressively brought into church membership through the individual rites of initiation, each contributing to a growing transformation in the candidates. They could be identified as family even prior to their ultimate, baptismal adoption as members. This article fills a significant gap in research on the late fourth century theology of initiation. It provides present-day catechists with a deeper understanding of their baptismal candidates’ ecclesiological status. It opens a Patristic and ecumenical vista into the relationship of non-Orthodox Christians with the Orthodox church.
Intersecting Inequalities: The Representation of Religious, Gender, and Sexual Identities in the Life of Pelagia
Authors: Bodnaruk Mariana 
Published: February 2022

Abstract
Repentant harlots who became trans saints presented Byzantine hagiographers with a challenge. Thought to exhibit a lack of self-control and the excessive sexuality, associated with women, and sex workers in particular, – a subject of great concern for monastic authors – how could members of this stigmatized group achieve the standards of Christian piety, let alone saintly behavior? In portraying its fictional protagonist as an exemplum of masculine virtues in the context of nascent Palestinian monasticism, the anonymous Life of Pelagia highlights the non-binariness of social identities in early Byzantium, unsettling fixed gender categorization. Conceiving of a trans figure of an ascetic subverting conventional binaries, the Life creates a model for incorporating non-conforming masculinities of Byzantine society within the normative hagiographic genre.
From Paganism to Christianity and the Administrative-Ecclesiastical Integration of the Parishes on the Middle Valley of Târnava Mare in the Twelfth to Fourteenth Centuries
Authors: Şvrea Adrian Nicolae 
Published: February 2022

Abstract
This paper aims at describing the process through which religious rites and rituals have changed within settlements located along the middle valley of the Târnava Mare River, evolving from pagan manifestations to the emergence of Catholic ecclesiastic institutions, contributing thus to a new regional religious identity. The archaeological findings of the Mediaş group indicates the practice of the cremation rite in this particular area, which was a common custom up until the mid-ninth century. In the following ninth to eleventh century period, however, there is a gap in archaeological evidence relevant to the funeral rite; no burial grounds or cemeteries have been identified, and only one settlement in Albeşti (Mureş County) was found. The Târnava Mare basin was shortly encompassed within the Hungarian Kingdom. Thus, starting with the twelfth century, a series of indagines were built and defended by the Szeklers’ communities. The cemetery on the so-called Dealul Viilor in Sighişoara is attributed to the Szeklers. A new burial ritual was observed, namely an anthropomorphic practice, after German populations settled down along the Târnava Mare valley and after the arrival of Dominican monks in Sighişoara, where they erected a Dominican convent. From an institutional point of view, these settlements were placed under the jurisdiction of the Transylvanian bishopric and of the chapters/ diaconates of Mediaş, Laslea/Criş, Târnava Mare, Târnava Mica, Saschiz, Tileagd.
Ad Subsidium Terrae Sanctae: Military Religious Orders and the Cismarine Expansion of the Borders of Christianitas
Authors: Todika Raul-Alexandru 
Published: February 2022

Abstract
This article aims to discuss the presence of the military religious orders at the frontiers of Christianitas during the twelfth and thirteenth centuries, a period when the hierocratic auctoritas ecclesiae materialized itself through vigorous expansionism. The military religious orders acted in consensus with the Holy See and at the request of the political European entities (also subjected to the authority of the Pope) in regions where they could not withstand the threats which endangered parts of their kingdoms or possessions. Ultimately this article integrates the presence of the Teutonic Knights in Transylvania during the first half of the thirteenth century in this broad mission of expansionism and highlights how the Roman Pontiş established relationships with the kingdoms positioned at the edge of Christianitas.
Preliminary Approach Regarding Eastern and Western Christian Churches in Medieval Maramureș County
Authors: Pop Ioana 
Published: February 2022

Abstract
The present research investigates the presence and coexistence of two denominations, the Western and Eastern Christian faith, in medieval Maramurefi county. For this, a close analysis of medieval published documents was performed. Along with these primary sources, the historiography of the subject was also consulted. The survey shows that both denominations were well-represented both institutionally and through active members, even if measures were taken by the bishops of Rome and kings of Hungary against the Eastern Christian faith in the realm. We hope that future archival and archaeological research will lead to new findings that will contribute to a better understanding regarding the historic coexistence of the two denominations in Maramureş County.
The Impact of Digitalisation on Slovenian Primary School Students in Eighth Grade

Published: February 2022

Abstract
Society is rapidly moving towards a digitalised future, encouraged by national and European guidelines and strategies. Use of computers, tablets and smartphones is not reserved only for adults: adolescents use them extensively for schoolwork and leisure activities. Although Internet use has many advantages, some students use it extensively in a way that harms them. The Problematic Internet Use Questionnaire used in a nationally representative sample of Slovenian primary school students in the eighth grade showed that one-quarter of them were problematic Internet users. Comparison of problematic and nonproblematic Internet users in the eighth grade showed different patterns of spending their free time: screen time prevailed in the first group. Problematic Internet users showed statistically significant lower levels of self-control in comparison with nonproblematic Internet users; they also reported a less favorable relationship with their parents. Evidence from abroad show that problematic Internet users among students are less successful at school. Career prospects of problematic Internet users are smaller, where discipline and self-control is expected. Adolescents need help in recognizing harmful effects of modern digital technologies and in learning to control their time spent on the Internet.
Assessing the Impact of the Digital Divide on Indian Society: A Study of Social Exclusion
Authors: Singh Swapnil , Singh Guru Ashish 
Published: February 2022

Abstract
The digital divide is an important issue in developing nations, especially during Covid-19 times. The notion of the digital divide gained prominence in the 1990s. The characterization of the idea of the digital divide has evolved with time and is currently recognized as “lack of knowledge, access or infrastructure.” It can be comprehended as a barrier for the general masses, particularly in developing countries. Information and communication technology (ICT) now occupies a significant role in our lives (especially in Covid-19 times). India is known for its social diversity. However, some groups and categories of people have historically been excluded and continue to be excluded today. This study focuses on the assessment of the impact of the digital divide on Indian society, specifically on the phenomenon of social exclusion because of the digitalization of almost all aspects of our lives. The research gap observed is that the digital divide can have serious concerns for future growth since it impedes social mobility, creates impediments, and exacerbates social inaccessibility for disadvantaged groups. To obtain an adequate sample size, respondents are chosen using simple random sampling technique of probability sampling. Statistical techniques such as validity and reliability analysis, T-test, ANOVA, and correlation-regression are used to present quantitative data. The study's expected outcome will be to provide a vigilant roadmap for policymakers and public institutions to strengthen nationhood among the masses while promoting social inclusion. Modern Indian society should strive for inclusion, and there should be no discrimination in terms of digital accessibility, which could paralyze the developing nation.

Published: February 2022

Heroes Park City Forest has a high vegetation density in Purworejo Regency, Central Java province, absorbing and storing carbon from the atmosphere. This study analyzes the value of carbon stock, sequestration, and tree composition in the Heroes Park City Forest. Data collection was carried out in February 2021, using three randomly distributed 20 x 100 m plots. Analysis of carbon stock data, important value index, and diversity index was carried out quantitatively descriptively. The results showed that the carbon stock value of trees was 116.84 tons ha-1, which according to Reducing Emissions from Deforestation and Forest Degradation or REDD+, was included in the high carbon stock category. The value of carbon sequestration in Heroes Park urban forest is 428.80 tons ha-1, which is higher than some city forests in Indonesia. The sampling location is covered with 157 tree species, dominated by Acacia auriculiformis, and has a moderate level of tree diversity. Vegetation dominated by Acacia auriculiformis from Fabaceae contributed 43 percent of the total carbon stock in Heroes Park. Abiotics such as rainfall, air temperature, and humidity in Purworejo City support the growth of plants from the Fabaceae. Therefore, Heroes Park City Forest in Purworejo Regency has high carbon storage or carbon stock and sequestration values and needs to be monitored annually to maintain this potential.

Published: February 2022

Limitations of observational data such as insufficient data length, incomplete, and uneven station distribution make it difficult to analyze and predict rain, so it requires supporting instruments such as satellites to provide a better and broader picture of rainfall distribution. However, it is necessary to test the accuracy of satellite data because the resolution and conditions of each region are different. This research aims to validate IMERG rain data against observation data in the 2015 El Nino period using observation rainfall data from BMKG Negara and IMERG data from GPM satellite at 12 rain points in Bali Province. The analytical method used is quantitative statistics, the calculation of errors and correlations and the comparison of the spatial pattern of the two data. The results of the analysis of the spatial pattern of the IMERG data show that, there was a decrease in rainfall from May to July, but the rainfall increased into August, and again experienced a decline entering the months of September to December where the same pattern was also shown from the results of the spatial pattern analysis on the Observation data. The decrease in rainfall in the May-December 2015 period was a strong El Nino effect as evidenced by the results of the correlation analysis of the SOI index on rainfall which showed a fairly strong correlation value, namely 0.55.The validation of IMERG data on monthly observation data showed that the average correlation was sufficient strong is 0.42 and analysis per rain post shows a weak correlation namely 0.31, which means that data IMERG is not yet accurate as an alternative to the observation rainfall data in Bali Province.

Telah dilakukan studi mengenai pengenalan pola reflektansi spektral sebagai indikator perubahan distribusi kerapatan mangrove menggunakan data time series citra Landsat 8, di daerah kawasan Teluk Benoa, Bali. Tujuan penelitian ini adalah untuk mengetahui distribusi kerapatan dan luas areal mangrove dari pola reflektansi spektralnya. Metode dan analisis menggunakan reflektansi spektral dan indeks vegetasi Normalized Difference Vegetation Index (NDVI). Hasil penentuan nilai reflektansi spectral menunjukkan bahwa, perubahan pola reflektansi spektral mangrove di Teluk Benoa dari tahun 2017-2020 mengalami penurunan dan kenaikan untuk setiap band-nya. Pola reflektansi band 5 dapat digunakan sebagai acuan terhadap pengurangan luasan areal mangrove, dimana semakin kecil nilai reflektansi pada band 5 dari tahun 2017-2020 menunjukkan pengurangan atau perubahan kerapatan mangrove di tahun tersebut semakin besar. Berdasarkan data sebaran citra indeks vegetasi NDVI pada tahun 2017-2020 diperoleh tutupan luas per kategori dimana terdapat pengurangan luas areal mangrove dari tahun 2017 hingga 2018 sebesar 36,72 ha, akan tetapi pada tahun 2019 luasan areal mangrove mengalami peningkatan yang cukup besar dari tahun 2018 yaitu sebesar 60,82 ha. Pada tahun 2020 luasan areal mangrove kembali mengalami pengurangan yang cukup drastis yaitu sebesar 181,51 ha. Luasan areal yang tercatat masih ditumbuhi mangrove pada tahun 2020 yaitu hanya sebesar 852,39 ha.

Analysis Regional Vulnerability of Earthquakes Based on Parameters Fragility Rock Value (B-Value) and Peak Ground Acceleration (PGA) In Bali Province
Authors: Lestari Amalia Dwi , Suarbawa Komang Ngurah , Supardi I Wayan , Pratama I Putu Dedy 
Published: February 2022

Abstract - Bali is an area that is prone to earthquake hazards. This is because Bali is flanked by two causes of earthquakes, namely a subduction zone in the south and a back arc fault in the north. One of the efforts to minimize damage or loss caused by earthquakes is to analyze the vulnerability of an area to earthquakes. In this study, the earthquake parameters used as hazard indicators were the level of rock fragility (b-value) and maximum ground acceleration (PGA). Based on the results of the b-value calculation using the Maximum Likelihood method, the rock fragility level for the Bali region is obtained from 0.370 to 1.419. While the results of the PGA calculation using two empirical methods, namely the empirical M.V. Mickey and Lin Wu's empirical method is known that the empirical method of M.V. Mickey is more suitable for use in the Bali area than Lin Wu's empirical method, with PGA values ??ranging from 517.32-828.58 gal. So based on the results of the analysis of the two earthquake parameters, it is found that the area of ??Bali that is vulnerable to earthquakes is the western part of Buleleng Regency and most of Jembrana Regency.
