Published: December 2021

Problem. Development and implementation of green technologies is both an urgent and a cost-effective scientific and engineering task. Therefore, the issues related to the study of renewable energy sources, which are used as the main sources of energy for electric vehicles, are quite relevant and promising. At the same time, an equally important question is how profitable is building solar charging stations in terms of both ecology and economy. Goal. The aim is calculation and analysis of technical and economic indicators of a solar charging station for electric vehicles (EV). Methodology. The analytical methods of studying the development and application of the ways and devices to transform the energy of the sun into electricity are used, as well as the methods of experimental research and mathematical methods of processing and modulation of the received results; methods of calculating technical and economic indicators. Results. The review of the literature on the development of renewable energy sources, in particular, solar power plants, and the spread of electric vehicles with the gradual displacement (replacement) of traditional cars working on internal combustion engines with electric vehicles (BEV and PHEV) was made. The main parameters and technical characteristics of the solar-powered charging station (SPCS) were studied. For the analysis and calculation of technical and economic indicators of SPCS for EV it is offered to take a SPP with a capacity of 20 kW as a basis. The calculation of SPCS electricity generation both for own consumption and for power supply of EV and the sale of surplus electricity to the general network at the “green tariff” was carried out. Originality. The technical and economic calculation of SCS was made taking into account the rise of electricity prices in Kharkiv region (Ukraine). Practical value. According to the analysis of the obtained results, it can be said that the payback period of SPCS for EV is about 7.9 years. If we consider the constant increase in the cost of electricity (approximately 15% per year), we can expect the payback after 6.8 years of operation.

Authors: NAZİFİ Buhari , BELLO Muhammadu , SULEİMAN Aminu , SULEİMAN Muhammad Sabiu
Published: December 2021

This study analyzed impact of contract farming on productivity and food security status of smallholder maize farmer’s household in Kano and Kaduna States, Nigeria. A multistage sampling technique was used to collect data from 466 smallholder maize farmers with the use of a-structured questionnaire. Descriptive statistics, household dietary diversity scores (HDDS), and propensity score matching were used to achieve objectives of the study. Result of descriptive statistics shown that, average age of contract participants was 39years; with farming experience of 20years and had an average farm size of 2.39 hectare. On the other hand, non-contract participants had an average age of 37years and average farming experience of 18years with a farm size average of 2.34hectare. HDDS result revealed households participating in contract farming to have mildly better food security status with an average dietary diversity score of 5.16, against non-contract participating farmers that have 3.15 household dietary diversity score average. PSM result for the impact revealed that contract farming had positively (P<0.01) impacted on maize yield (ATT=1.7ton/ha), and food security status of the participating household (ATT=0.893). Therefore participation in maize contract farming increases productivity and reduces food insecurity status of smallholder maize farmers; it can therefore be recommended that contract farming can be used as an instrument to reduce food insecurity and poverty among rural farming household.

Authors: AYDIN Fatma , KAHRAMAN Zeynep Aleyna , TÜRKOĞLU Emir Alper , KUZU Müslüm , SEVEROĞLU Zeki
Published: December 2021

Carbonic anhydrases (CAs; EC 4.2.1.1) are essential family of metalloenzymes which catalyze the interconversion between carbon dioxide (CO2) and bicarbonate (HCO3-) in all organisms of three-domains of life. Huge amounts of attempts related to catalytic activity of CAs have been widely expanded to treat many clinical diseases. This study aimed to determine in-vitro antioxidant activities and human CA I (hCA I) and II (hCA II) inhibitory properties of Ferula communis extracts. Among all extracts of F. communis, the hexane extract has showed the best inhibitory profile on hCA I and II with IC50 values 8.68 µg/mL and 28 µg/mL and Ki values 2.026 µg/mL and 11.6 µg/mL, respectively. All extracts showed mild to moderate antioxidant activity. According to the results of DPPH assay, ethanol-water extract showed the highest activity with IC50: 0.1128±0.0066 value. Chloroform extract showed the highest activity on CUPRAC assay with the value of 1.305±0.037 mM Trolox equivalent/mg extract. However, further analytical, in-vivo and clinical studies are needed to confirm the activities of F. communis.
La fauna de Loma l’Ántigo. Primeros datos zooarqueológicos del Período Desarrollos Regionales del valle del Cajón, Catamarca, ca. 1200-1500 d.C.
Authors: Belotti López de Medina Carlos Raúl , Bugliani María Fabiana
Published: December 2021

This paper reports the results of the analyses conducted on the archaeofaunas from the Loma l´Ántigo archaeological site (Cajón valley, Catamarca province). Loma l´Ántigo is a conglomerate settlement that rests on the top of a flattened hill, and which was dated to the Regional Developments archaeological period. The archaeofaunas were recovered from nine test-pits and the area excavation of three enclosures (structures E25, E66 and E93). Camelidae is both the most ubiquitous family between assemblages and the most abundant across them. Camelid specimens comparable to both domestic and wild species were recorded, and age profiles include young, subadult, adult and old animals. Loma l´Ántigo assemblages do not exhibit significant differences against archaeofaunas dated to the Formative Period of the Cajón valley (Cardonal and Yutopián sites), pointing to a broad continuity of modes of faunal exploitation and to similar environmental and sociocultural constraints on taphonomic histories, despite previously posited demographic, political and climate changes around the beginning of the second millennium AD for the Southern Calchaquí valleys.
Primera aproximación al consumo doméstico de fauna en ocupaciones rurales del sur de Pozuelos (Puna de Jujuy, Argentina) en tiempos tardíos y coloniales (siglos XIII a XVIII)
Authors: Torres Vega Lucrecia Marina R. , Angiorama Carlos I. , Mercolli Pablo H.
Published: December 2021

El análisis comparativo de distintos conjuntos zooarqueológicos recuperados en sitios del sur de la cuenca de Pozuelos (puna de Jujuy, Argentina), con fechados que los ubican entre los siglos XIII y XVIII, nos permite reconocer algunos aspectos de las prácticas de consumo de fauna y de manejo de rebaños por parte de los antiguos pobladores locales. Además de considerar las transformaciones y persistencias a través del tiempo, contemplamos las variaciones funcionales de las ocupaciones analizadas, así como también aspectos contextuales. Los camélidos constituyen la especie más representada en todos los conjuntos, haciendo visible el consumo de recursos pastoriles durante toda la secuencia. Para las ocupaciones de los siglos XIII y XIV hemos registrado camélidos silvestres, siendo muy escasa la presencia de otros taxones en las muestras, mientras que en las ocupaciones fechadas en tiempos coloniales se destaca la ausencia de fauna europea en los contextos excavados. Las clases de edad nos permiten dejar planteada la hipótesis que afirma que se practicaron estrategias mixtas de explotación de recursos, al menos para los siglos XIII y XIV. Finalmente, las semejanzas y divergencias encontradas entre los conjuntos, parecen más bien estar en relación con las particularidades que adquirieron las ocupaciones domésticas.

Sexual education for adolescents: parent role in rural area
Authors: Waliyanti Ema , Dewantari Ratna Ajeng
Published: December 2021

Health problems faced by adolescents when they are very varied and related to risky sexual behavior. Sexual education is currently still considered taboo by the public because it is less appropriate to talk about and is private. The purpose of this study was to explore the role of parents in sexual education in adolescents. This study uses a qualitative research method with a phenomenological approach. Data were collected by means of in-depth interviews with 12 participants who were determined by purposive sampling. The saturation data with 5 parent and 7 adolescents. Data validity test used source triangulation, member cheking, peer debrifing, and thick description. Data analysis using open code 4.03 software. This research is ethical with number No. 020 / EC-KEPK FKIK UMY / I / 2021.Â  The results showed that the role of parents in providing sex education to adolescents was caused by several factors, namely the closeness of children to their parents, parental education, parental divorce, parents' perceptions of sex education, perceptions of the importance of sex education, and parenting styles of parents to child, which affect the optimal role of parents in sex education for their children. To conclude, it is important for parents to provide sexual education to prevent risky sexual behavior, such as providing sexual education for adolescents, giving advice to children, supervising children's relationships, and providing rules for children.
Slow-light effect in symmetry-reduced non-defect photonic crystals
Authors: GİDEN İbrahim Halil
Published: December 2021

In this study, a two-dimensional low-symmetric photonic crystal (PC) configuration with elliptical geometry is presented and its slow-light (SL) effect is investigated. Reducing the symmetry in the PC unit cell provides slow modes at the higher transverse electric bands. The calculated group index and the corresponding normalized bandwidth equal to {ng, BW}={63.56, 0.0065}. That corresponds to a value of figure of merit (FOM)=0.4344 defined by the product of the average group index and the normalized bandwidth, FOM=〈ng〉BW, which is comparable to the values available in literature. Tracing the whole edges of the Brillouin zone, strongly excited SL modes are observed only along Γ-X but not along Γ-X’ or Γ-M. That condition allows for the design of low-symmetric PC waveguides with finite thicknesses at the expense of lowering group index value. The SL effect is still obtained for the proposed low-symmetric PCs having finite thicknesses, which is numerically proved via finite-difference time-domain methods. It is important to note that non-dispersive SL Bloch modes exist through the non-zero k-vector components of Brillouin zone. Hence, such a defect-free (without either point- or line- defect) SL PC design may have a great potential for the use of compact photonic devices such as in optical switching and biochemical sensing applications.

Modeling The Mysterious Tsunami Swirls In The Northeast Coast Of Japan During The March 2011 Tohoku Earthquake
Authors: Rivera Paul C.
Published: December 2021

The formation of tsunami swirls near the coast is an obvious oceanographic phenomenon during the occurrence of giant submarine earthquakes and mega-tsunamis. Several tsunami vortices were generated during the Asian tsunami of 2004 and the great Japan tsunami of March 2011 which lasted for several hours.New models of tsunami generation and propagation are hereby proposed and were used to investigate the tsunami inception, propagation and associated formation of swirls in the eastern coast of Japan. The proposed generation model assumes that the tsunami was driven by current oscillations at the seabed induced by the submarine earthquake. The major aim of this study is to develop a tsunami model to simulate the occurrence of tsunami swirls. Specifically, this study attempts to simulate and understand the formation of the mysterious tsunami swirls in the northeast coast of Japan. In addition, this study determines the vulnerability of the Philippines to destructive tsunami waves that originate near Japan. A coarse resolution model was therefore developed in a relatively large area encompassing Japan Sea and the eastern Philippine Sea. On the other hand, a fine-resolution model was implemented in a small area off Sendai coast near the epicenter. The model result was compared with the tsunami record obtained from the National Data Buoy Center with relatively good agreement as far as the height and period of the tsunami are concerned. Furthermore, the fine-resolution model was able to simulate the occurrence of tsunami vortices off Sendai coast with various sizes that lasted for several hours.

The Urgency and Role of Emoji and PUEBI-Compliant Spelling Applications in Digital Communication to Minimize Misunderstanding Among Airlangga University Students
Authors: Afi Walidil , Setianingrum Amanda Putri , Adjie Bagas Respati , Pandin Moses Glorino Rumambo
Published: December 2021

The existence of CMC (Computer-Mediated Communication) has influenced the pattern of human communication, which was initially face-to-face, to become more accessible by using electronic devices. So that the communication process can be carried out more flexibly even though they are separated by distance. However, communication through electronic devices has limitations in conveying messages and providing the opportunity for the recipient to understand the message because CMC (Computer-Mediated Communication) does not include nonverbal communication such as expressions and feelings. Therefore, communication through electronic devices depends on the use of language only. However, people tend to make language errors in digital communication such as omission or punctuation errors, spelling errors and inappropriate PUEBI, abbreviated words, and complex words to understand. These two conditions certainly impact the digital communication process because people are at risk of experiencing misunderstandings with different perceptions between the two. This research aims to determine the urgency and role of emoji and PUEBI-compliant spelling in digital communication among Airlangga University students. This research method is descriptive qualitative by applying the purposive sampling technique. The respondent's criteria are undergraduate students from Universitas Airlangga who have experience in digital communication. Data were collected through surveys and literature studies to obtain detailed information on the research topic. The results show that using emoji and good spelling is critical in digital communication because of limitations in delivering nonverbal communication and semantic errors that affect misunderstandings between communicators and communicators. Emojis and spellings that match The General Guideline for Indonesian Spelling (Pedoman Umum Ejaan Bahasa Indonesia [PUEBI]) can clarify messages so that the intent can be adequately conveyed, change the tone or intonation of speech, channel and represent the sender's expression, and give an impression to the sender of the message.

Spatial Modeling of Tsunami Vortices in the Coastal Ocean
Authors: Rivera Paul C.
Published: December 2021

It is important to plan for potential tsunamis during the marine spatial planning process so that land uses may be modified or defensive infrastructure may be erected. Tsunami vortices had been observed during the occurrence and propagation of tsunami waves. Actual observations during the March 2011 Japan tsunami and the Indian Ocean tsunami of December 2004 showed the formation of vortices which lasted for several hours. The Palu tsunami of September 2018 in Indonesia also showed the formation of a tsunami vortex whose centre was photographed by a pilot and appeared as a deep hole in the ocean. Several vortices with various sizes lasted for several hours after the quake and they also generated a loud roar as the giant waves inundated low-lying coastal areas. This essay attempts to describe the development of a model that can explain the formation of tsunami vortices.

A Novel Convolutional Neural Network for Classifying Indian Coins by Denomination
Authors: Chauhan Yash , Singh Prateek
Published: December 2021

Coins recognition systems have humungous applications from vending and slot machines to banking and management firms which directly translate to a high volume of research regarding the development of methods for such classification. In recent years, academic research has shifted towards a computer vision approach for sorting coins due to the advancement in the field of deep learning. However, most of the documented work utilizes what is known as ‘Transfer Learning’ in which we reuse a pre-trained model of a fixed architecture as a starting point for our training. While such an approach saves us a lot of time and effort, the generic nature of the pre-trained model can often become a bottleneck for performance on a specialized problem such as coin classification. This study develops a convolutional neural network (CNN) model from scratch and tests it against a widely-used general-purpose architecture known as Googlenet. We have shown in this study by comparing the performance of our model with that of Googlenet (documented in various previous studies) that a more straightforward and specialized architecture is more optimal than a more complex general architecture for the coin classification problem. The model developed in this study is trained and tested on 720 and 180 images of Indian coins of different denominations, respectively. The final accuracy gained by the model is 91.62% on the training data, while the accuracy is 90.55% on the validation data.
Assessing how we decide: Psychometric development of a decision modes scale
Authors: Forster Hale A , Bottesini Julia G. , Reeck Crystal , Weber Elke U.
Published: December 2021

We present the development of the Domain-general Decision Mode Scale (DDMS), a 24-item scale to measure decision modes. Decision modes are the qualitatively different approaches through which individuals report making decisions. Researchers have consistently acknowledged that existing two-systems models of decision-making processes that distinguish between an intuitive and a rational mode do not account for the range of rule-based processes that decision makers employ in evaluating and making choices. Our studies identified six different decision modes, driven respectively by calculation, affect, habit, social norms, identity, and morality. Making a decision using the calculation mode involves a deliberate process of assessing costs and benefits. Using the affective mode involves an emotion- or gut-driven process. Using the social norms mode involves consideration of what others are doing or what others condone as appropriate. Using the habitual mode involves following a previously determined rule or habit. Using the identity mode involves identifying what is consistent with one’s sense of self or own values. Finally, using the moral decision mode involves consideration of what does the most good. We conceptually group the final four decision modes under the umbrella of rule-based decision-making: making a decision based on previously-learned and/or socially-derived conventions. The DDMS exhibits good reliability, as well as convergent and discriminant validity. By providing a scale that assesses the degree to which decision makers report using these decision modes, we integrate past research on decision modes and create a framework for additional research into the effects of different decision processes.
Trends in Family Physician Usage among Canadians from 2001 to 2016: An Age-Period-Cohort Analysis
Authors: Yeung Jessie
Published: December 2021

As primary health care providers, family physicians play a critical role in Canada’s health care system by providing first-level contact for patients and acting as advocates for preventative medicine. Due to their essential role in population health, public health practitioners are concerned about temporal trends surrounding family physician visits. This study uses eight cycles of the Canadian Community Health Survey, a nationally representative survey, to conducing an age-period-cohort analysis with the bounding method, while controlling for sex and race. Most notably, we discover a declining cohort trend indicating that later cohorts are less likely to visit a family doctor over a 12-month period. These results suggest that health promotion policies surrounding family physician use should not only be targeted towards middle and older-aged adults who experience declining health, as the cohort effect implies that a portion of health care avoidance behaviour is molded in youth and young adulthood.

Background: This study examines previous research and open-source data to analyze COVID-19’s impact on youth mental health. It evaluates how certain factors, such as geographical location, race, and sexual orientation, may increase a child’s likelihood of developing a mental disorder during the pandemic.Methods: We statistically analyzed the open-sourced COVID-19 and its Impact on Students data set. We filtered the responses so that our results included participants who were under 18 years of age. Google Sheets and Microsoft Excel were used to plot survey data and analyze correlations.Results: Students ages 7-17 spent an average of 0.82 h/day [95% CI 0.76–0.89] exercising, 7.91 h/day [95% CI 7.77–8.11] sleeping, and 1.68 h/day [95% CI 1.52 – 1.85] using social media. Time spent in online classes for students ages 7-17 was significantly higher compared to other age groups (3.69 h/day). 31.5% of students in this group negatively reviewed their quality of e-learning (2.4% poor and 29.1% very poor). Additionally, 51.4% of responders were not satisfied with their use of time. Further testing revealed emotional and cognitive health declined sharply in participants dissatisfied with their use of time. To cope with the pandemic, 26% of the surveyed students listened to music, 21% played online games, 9% read, 9% used social media, 8% slept, and 27% used other methods.Conclusions: After a conclusive review of previous research, we can confirm that COVID-19 harmed children’s emotional and cognitive health to a great extent. Although the seriousness of psychological symptoms felt by young people varied from region to region, COVID-19 led to an overall decline in mental health in groups ages 7-17. Hopefully, health officials will recognize the mental health crisis at hand and will devise new means to support children’s psychological health.
LBS as Vectors of Influence
Authors: Gartner Maximilian
Published: December 2021

Due to their technical capabilities and use-cases, LBS can impose autonomy constraints on individuals, both through direct interaction and via indirect means. This essay outlines four main interaction characteristics that constitute LBS as a vector of influence and contextualizes them by mapping them onto a pragmatic framework of autonomy.
La formación de profesores/as de inglés como intelectuales: algunas anotaciones epistemológicas
Authors: García Juan Carlos Vásquez
Published: December 2021

El presente texto aborda, de manera reflexiva, un proceso gnoseológico posible en la formación de profesores de inglés intelectuales. Para ello, se recurre a la investigación narrativa y a la narración de sí, como puentes entre la conciencia de masas y la autodeterminación necesaria para descubrir problemas existenciales y desarrollar el deseo y las capacidades para resolverlos. Se concluye que la narración de sí en la formación de docentes, a través del abordaje de narrativas literarias y/o científicas, y la respectiva discusión a la luz de la realidad de la cual surge y de textos académicos que permita interpretarla puede ser una estrategia posible por medio de la cual los/as futuros/as docentes pueden desarrollar prácticas pedagógicas liberadoras, que haga de ellos/as docentes intelectuales.
A new method to explore inferential risks associated with each study in a meta-analysis: An approach based on Design Analysis
Authors: Giorgi Francesca
Published: December 2021

In the last ten years, scientific research has experienced an unprecedented “credibility’s crisis” of results. This means that researchers couldn't find the same results as in the original ones when conducting replication studies. In fact, the results showed that effects size were often not as strong as in the original studies and sometimes no effect was found. However, an important side-effect of the replicability crisis is that it increased the awareness of the problematic issues in the published literature and it promoted the development of new practices which would guarantee rigour, transparency and reproducibility. In the current work, the aim is to propose a new method to explore the inferential risks associated with each study in a meta-analysis. Specifically, this method is based on Design Analysis, a power analysis approach developed by @gelmanPowerCalculationsAssessing2014, which allows to analyse two other type of errors that are not commonly considered: the Type M (Magnitude) error and the Type S (Sign) error, concerning the magnitude and direction of the effects. We chose the Design Analysis approach because it allows to put more emphasis on the estimate of the effect size and it can be a valid tool available to researchers to make more conscious and informed decisions.

Identification of high altitudinal vegetation dynamics using remote sensing is important because of the complex topography and environment in the Himalayas. Langtang National Park is the first Himalayan park in Nepal representing the best area to study vegetation change in the central Himalaya region because of the high altitudinal gradient and relatively less disturbed region. This study aimed at mapping vegetation in Langtang National Park and its treeline ecotone using Moderate Resolution Imaging Spectroradiometer (MODIS), Normalized Difference Vegetation Index (NDVI). Two treeline sites with an altitude of 3927 and 3802 meters above sea level (masl) were selected, and species density was measured during the field survey. The linear slope for each pixel and the Mann Kendall test to measure significant trends were used. The results showed that NDVI has significantly increased at the rate of 0.002yr-1 in Langtang National Park and 0.003yr-1 in treeline ecotone during 2000-2017. The average 68.73% equivalents to 1463 km2 of Langtang National Park are covered by vegetation. At the same time, 16.45% equivalents to 350.43 km2 are greening, and 0.25%, i.e., 5.43 km2 are found browning. In treeline ecotone, the vegetation is mostly occupied by grasses, shrublands and small trees where the NDVI was found from 0.1 to 0.5. The relative changes of NDVI in barren lands are negative and vegetative lands above 0.5 NDVI are positive between 2000 and 2017. The dominant treeline vegetation were Abies spectabilis, Rhododendron campanulatum, Betula utilis and Sorbus microphyla, with the vegetation density of 839.28 and 775 individuals per hectare in sites A and B, respectively. The higher average NDVI values, significantly increased NDVI, and higher density of vegetation in both A and B sites indicate that the vegetation in treeline ecotone is obtaining a good environment in the Himalayas of Nepal.

Rivers and lakes are important habitats for both resident and migratory wetland-dependent birds. This paper presents the study of birds’ seasonal diversity in Sani Bheri River Valley, outside the protected areas of Nepal. The study was carried out from 8-17 March 2019 (Spring) and 12-21 October (Autumn) 2019 covering a 52 km river stretch from Naighat (upstream area where Pelma River and Uttarganga River mix and flow as Sani Bheri river) to Remnaghat (downstream towards the confluence with Thuli Bheri) using the Mackinnon Listing method. The present study recorded 851 occurrences belonging to 11 Orders, 33 Families, and 71 bird species. Order Passeriformes (52 species) and family Muscicapidae (13 species) were dominant. Plumbeous Water-redstart (Phoenicurus fuliginosus) had the highest relative abundance (7.64%). Shannon-Weiner diversity index (H’= 3.61) and Evenness index (e= 0.85) indicate the diverse assemblage of avian fauna in the study area. This study showed that Sani Bheri River Valley provides the habitat for one globally threatened, four nationally threatened, and eight species listed in Appendix-II of CITES. The results provide the baseline information on avian species, which can provide a good database and can be incorporated in conservation implications.
