Premise: The invasive tetraploid Cirsium vulgare hybridizes with both Cirsium and Lophiolepis. Its conflicting position in molecular phylogenies, and its peculiar combination of morphological, anatomical, and genomic features that are alternatively shared with representatives of Cirsium or Lophiolepis, strongly suggest its intergeneric hybrid origin.
Methods: Genetic relationships of C. vulgare (8 samples) with genus Lophiolepis (11 species) and other representatives of genus Cirsium (12 species) were evaluated using restriction site-associated DNA sequencing (RADseq) and examined using analytical or imaging approaches such as NeighborNet, Heatmap, and STRUCTURE to identify genomic nuclear genome admixture. Estimation of the intensity of spontaneous hybridization within and between Cirsium and Lophiolepis was based on herbarium revisions and a recherche of all reported hybrids pertinent to taxa currently included in Cirsium or Lophiolepis.
Key results: The genome of any examined Cirsium species is more similar to C. vulgare than to any Lophiolepis species, and vice versa. The nuclear genome of tetraploid C. vulgare is composed of two equivalent parts, each attributable either to Lophiolepis or to Cirsium; the organellar RADseq data clustered C. vulgare with the genus Cirsium. Spontaneous hybridization between Cirsium and Lophiolepis is significantly less intensive than within these genera.
Conclusions: Our analyses provide compelling evidence that the invasive species C. vulgare arose by an allotetraploid intergeneric origin with the maternal parent from Cirsium and the paternal from Lophiolepis. For the purpose of delimiting monophyletic genera, we propose to keep Lophiolepis separated from Cirsium and to segregate C. vulgare into the hybridogenous genus Ascalea.

Impacts of Housing Tenure Choice and Mortgage Payment on Household’s Propensity to Consume
Authors:   Korea Urban & Real Estate Association, Kim Chunil
Published: October 2023

Households, who buy a house, would initially spend less because some equity investment is inevitable. They, however, get to be better off later in terms of household consumption than renters once they enter the stage of paying off the mortgage debt regularly because the uncertainty on how much they save for housing purchase in the future is eliminated. The purpose of this study is twofold: (1) to explore the impact of propensity to own a home on household’s propensity to consume, and (2) to test whether or not the amount of mortgage payment has a crowd-out effect on the propensity to consume. As for the empirical analysis, this study employed the two-step estimation methodolgy to address the potential reverse causality and sample selection bias in the relationship of housing tenure choice with propensity to consume, and in the linkage of mortgage payment with propensity to consume, respectively. This study provides evidence that those effects are significant, and they are greater for lower-income households. These findings justify the differentiated policy tools by income in devising and executing micro- and macro-prudential measures.
A Study on the Factors Affecting the Fee Rate of Trust-type Maintenance Projects
Authors:   Korea Urban & Real Estate Association, Kim Jung-Hoon , Park Jae Ra , Choi Chang-Gyu
Published: October 2023

Recently, interest and demand for “trust method maintenance projects” are increasing in order to promote stable projects in a number of maintenance projects (planned) areas due to rapid housing supply centered on public redevelopment projects and Moa Town projects in Seoul. The “Trust Method Maintenance Project” was introduced in September 2015 as an amendment to the “Urban and Residential Environment Maintenance Act” to solve the problem of delays in project promotion and lack of expertise. Previous studies mainly discussed how to activate trust method maintenance projects and differences from existing union methods, and studies on the “Trust Fee rate”, a major factor in determining trust methods, are rare. This study derives variables that affect the trust fee rate for the entire domestic trust method maintenance project from January 2016 to December 2021, when the trust method maintenance project was implemented. Based on this, multiple regression analysis analyzed which variables affect the trust fee rate and confirmed that “new total floor area”, “the size of the trust company (small)” and “regional impact (local)” were influencing factors. In other words, it was verified that the size of the project and the degree of risk of the project's progress have an effect on the trust fee rate. This study is significant in that it is the first study on the trust fee rate of trust method maintenance projects that have not been covered in previous studies after investigating the entire trust method maintenance project site in Korea. In the future, this study is expected to be used as a basis for judging the choice of trust method maintenance projects for owners such as unions or land.
End-to-End Steering Angle Prediction for Autonomous Car Using Vision Transformer
Authors: Sonata Ilvico , Heryadi Yaya , Wibowo Antoni , Budiharto Widodo
Published: October 2023

The development of autonomous cars is currently increasing along with the need for safe and comfortable autonomous cars. The development of autonomous cars cannot be separated from the use of deep learning to determine the steering angle of an autonomous car according to the road conditions it faces. In the research, a Vision Transformer (ViT) model is proposed to determine the steering angle based on images taken using a front-facing camera on an autonomous car. The dataset used to train ViT is a public dataset. The dataset is taken from streets around Rancho Palos Verdes and San Pedro, California. The number of images is 45,560, which are labeled with the steering angle value for each image. The proposed model can predict steering angle well. Then, the steering angle prediction results are compared using the same dataset with existing models. The experimental results show that the proposed model has better accuracy regarding the resulting MSE value of 2,991 compared to the CNN-based model of 5,358 and the CNN-LSTM combination model of 4,065. From the results of this experiment, the ViT model can replace the existing model, namely the CNN model and the combination model between CNN and LSTM, in predicting the steering angle of an autonomous car.

Published: October 2023

The present study reports the adsorptive potential of an alternative and regenerative adsorbent, lead sulphide (PbS) modified with calix[4]arene towards a methyl orange (MO) dye solution. The chemical and morphological aspects of synthesised PbS nanoparticles and calix[4]arene-modified PbS were analysed by FESEM, EDX and FTIR, which indicated successful immobilisation of calix[4]arene on the PbS surface. The response surface methodology (RSM), based on central composite design (CCD), was conducted to evaluate the significant factors and to optimise the influence of various factors (adsorbent dosage, contact time and pH) on the adsorption of MO. Under optimal conditions (pH of 4, a dosage of 89.70 mg and a contact time of 129.76 min), the maximum adsorption of MO by calix[4]arene-modified PbS was observed. The MO uptake behaviour was well described by the Freundlich model and the pseudo-second-order kinetic model, indicating a multilayer chemical adsorption with a maximum adsorption capacity (qmax) of 3.268 mg/g. The adsorption mechanism of MO dye on the surface of calix[4]arene-modified PbS can be attributed to various interactions such as dipole–dipole hydrogen bonding interactions, Yoshida hydrogen bonding, π–π interactions and electrostatic interaction. The results strongly demonstrated the use of novel adsorbents, calix[4]arene-modified PbS and a reusability strategy as an alternative adsorbent in MO dye removal.
Separation of binary and ternary oil/water mixtures from a highly hydrophobic metal mesh
Authors: Wu Weibin , Zhang Hang , Qiao Zhuangzhuang , Cai Xiaomei , Liao Guiling , Lei Tingping
Published: October 2023

A highly hydrophobic metal mesh has great potential for its application in oil/water separation due to its special wettability. However, most current oil/water separation devices are simple with limited separation capacity. A separation device based on a highly hydrophobic metal mesh was constructed for different types of oil/water mixtures. Experimental results show that the device not only can be used for the continuous separation of binary oil/water mixtures of any density ratios but also can realize the simultaneous separation of heavy oil/water/light oil ternary mixtures. This achievement is meaningful for practical applications, which will gain great interest in the future.

Effects of an Introduced Benthivorous Fish on Macroinvertabrates Diversity in a Semiarid Shallow Lake
Authors: Cardoso Maria Marcolina Lima , Souza Artur Henrique Freitas de
Published: October 2023

The Cyrinus carpio Linnaeus, 1758 (common carp) is a widely introduced species for commercial purposes. However, its detrimental effects on lakes and reservoirs, such as a decrease in water quality, abundance and richness of macrophytes, and macroinvertebrate abundance, are also known. In this study, we investigated the effect of common carp introduction on the macroinvertebrate community in a shallow lake in the Brazilian semiarid region. The study in Panati lake took place between 2002 and 2008 with the introduction of common carp in 2004. Shallow lakes from Our results showed that after common carp introduction, there was a significant reduction in the richness and diversity of the macroinvertebrate community, as well as an increase in the dominance of certain groups, such as chironomids. The decrease in richness and diversity is likely a result of the decline in abundance of key dominant benthic groups and species, such as the gastropods Pomacea lineata (Spix, 1827), Biomphalaria straminea (Dunker, 1848), Aplexa marmorata (Guilding, 1828) and Plesiophysa ornata (Haas 1938), oligochaetes, and ostracods, as well as several insect families. This decline may also lead to increased variability (destabilizing effect) among gastropods, annelids, and crustaceans, as well as an increase in the variability of richness and diversity among benthic macroinvertebrate species

Objetivou-se avaliar a qualidade da água de poços domésticos, por meio de parâmetros físico-químicos e microbiológicos, em quatro comunidades rurais do sudoeste da Amazônia. Foram coletadas um total de 24 amostras de água nos períodos seco e chuvoso, e analisados os parâmetros temperatura, pH, sólidos totais dissolvidos, oxigênio dissolvido, condutividade elétrica, alcalinidade, ortofosfato, amônia, nitrito, nitrato, nitrogênio total, coliformes tolerantes e coliformes totais. A temperatura da água foi maior no período chuvoso em todas as comunidades estudadas. A condutividade elétrica oscilou entre 10 a 93 μS cm-1, a alcalinidade entre 6,41 a 27,3 mg L-1 e o nitrogênio total entre 1,2 a 7,57 mg L-1. O pH nas comunidades Paraíso Grande e Paraísinho estão em conformidade com a Resolução do Ministério da Saúde, mas a cor aparente excedeu o limite permitido nessas mesmas comunidades. Os sólidos totais dissolvidos, nitrito e nitrato estão abaixo do nível de tolerância do Ministério da Saúde, enquanto o valor médio de 2,90 mg L-1 de amônia está acima do permitido na comunidade Paraíso Grande. A presença de coliformes totais foi detectada em pelo menos um período nas comunidades Paraíso Grande, Cristolândia e Paraísinho, e apenas nesta última detectou-se Escherichia coli.
As Interações da Soja com os Microrganismos do Solo: Uma Breve Revisão sobre os Aspectos Biológicos e Agronômicos
Authors: Rodrigues Saulo Fernandes , Santos Giulia da Costa Rodrigues dos , Antunes Luiz Fernando de Sousa
Published: October 2023

A soja é a leguminosa de extrema importância para a alimentação humana e animal. O aumento da sua produtividade nos últimos anos é decorrente do melhoramento da espécie e desenvolvimento de novas cultivares, bem como a adoção de tecnologias de manejo e utilização de organismos promotores do crescimento vegetal, representados por bactérias e fungos. Destarte, esse trabalho teve como objetivo a realização de uma revisão de literatura acerca das funcionalidades das comunidades microbianas do solo, buscando verificar o que há de mais novo sobre as interações entre os microrganismos do solo com a produção agrícola da soja e como são os mecanismos que contribuem para o desenvolvimento vegetativo da cultura. Nesse sentido, bactérias, como as dos gêneros Rhizobium e Bacillus, e de fungos, como o Trichoderma, tornaram-se bem conhecidos na cultura da soja, auxiliando as plantas a crescerem de forma mais saudável e resilientes aos estresses abióticos e bióticos. Outro ponto que contribui, e não pode ser esquecido na cultura da soja, é para o adequado manejo da cultura. O sistema de plantio direto, por exemplo, ao utilizar diferente culturas como cobertura do solo, podem favorecer determinados grupos de microrganismos em detrimento de outros. Assim, a utilização dos inoculantes microbianos, sejam eles à base de bactérias ou fungos, ganha cada dia mais notoriedade e consciência de quem faz seu uso. Considerado como um método ambientalmente amigável, microrganismos podem ser a alternativa para promover melhorias no desempenho agronômico de diversas culturas e até substituir, como no caso do nitrogênio, a aplicação de fertilizantes químicos, os quais causam efeitos negativos no meio ambiente.
Circadian Rhythms and Sleep Disorders Associated to Major Depressive
Disorder: Pathophysiology and Therapeutic Opportunities
Authors: Manosso Luana M. , Duarte Luciano A. , Martinello Nicoly S. , Mathia Gisiane B. , Réus Gislaine Z.
Published: October 2023

Major depressive disorder (MDD) is a complex mood disorder. While much progress has
been made in understanding the pathophysiology of MDD, no single mechanism can explain all
facets of this disorder. Several studies show that disturbances in biological rhythms can lead to the
development of MDD. Indeed, insomnia or hypersomnia are symptoms included in the MDD diagnostic
criteria. Clinical studies and meta-analyses showed a strong relationship between MDD and
sleep disorders. Sleep disorder and MDD are associated with activation in the hypothalamicpituitary-
adrenal (HPA) axis and inflammation. The increase in inflammatory response can activate
the kynurenine pathway, decrease serotonin synthesis, and affect other factors involved in the pathophysiology
of neuropsychiatric conditions. Moreover, sleep disorders and MDD can change the gut
microbiota and alter the microbiota-gut-brain axis. Thus, this review discusses the relationship
between MDD, circadian rhythms, and sleep disorders, describing the potential pathophysiological
mechanism shared in these conditions. In addition, therapeutic opportunities based on antiinflammatory,
antioxidant, HPA axis regulatory, and synapse-modulating actions are raised. For the
article search, we used the PubMed database. Both sleep disorders and changes in biological
rhythms have a bidirectional relationship with MDD. Although some pathophysiological mechanisms,
including inflammation, changes in the gut microbiota, and decreased neuroplasticity, may
be involved in the relationship between sleep, circadian rhythms, and MDD, other mechanisms are
not yet well understood. Therapeutic opportunities based on anti-inflammatory, antioxidant, HPA
regulatory axis, and synapse modulating actions appear to be promising targets in preventing MDD,
circadian rhythm disturbances, and sleep disorders.
The Pneumatic Motor with Linear Cylinders
Authors: Rufer Alfred
Published: October 2023

A pneumatic motor is studied where the pneumatic actuators consist of
linear cylinders. This mechanical principle based on the use of a crankshaft and piston
rods has the inherent property of being reversible. For this system, the same principle
of adding expansion work with an additional volume is applied as it was in the previous
chapter for semi-rotary actuators.
The mechanical behavior of the crankshaft and piston rod is described, and the
following pneumatic displacement and expansion work is simulated. Two different
architectures are simulated, namely, first, a system with pistons operating in phase and
second, with alternating pistons. The energy efficiency of the new motor is calculated
and compared with the efficiency of a system using a single linear cylinder.
Further, the principle of realizing the expansion work in the same cylinder as for the
displacement work is applied to the motor with linear cylinders. The torque, power and
converted work are presented with the simulation results. The study is completed with
the presentation of a physical demonstrator system.
Toxicity of Nanomaterials-Physicochemical Effects
Authors: Morteza Naghib Seyed , Reza Garshasbi Hamid
Published: October 2023

Nanoparticles (NPs) have the potential to produce deleterious effects on
organ, tissue, cellular, subcellular, and protein levels due to their peculiar
physicochemical features. Metal NPs are gaining prominence and are being used in a
variety of medicinal, consumer, industrial, and military applications. Furthermore, as
particle size falls, some metal-based NPs become increasingly poisonous, despite the
fact that the same substance is rather innocuous in its bulk form. NPs can also interact
with proteins and enzymes within human cells, causing reactive oxygen species to be
produced, an inflammatory response to be initiated, and mitochondrial disruption and
destruction, ending in apoptosis or necrosis. As a result, deciding whether the
advantages of NPs outweigh the hazards presents various challenges.

As dedilhações do álbum Gradual para piano de Eurico Thomaz de Lima (1908–1989) como evidência de um pensamento técnico consolidado
Authors: Pipa Luís
Published: October 2023

A criação de peças e exercícios para jovens pianistas tem sido, ao longo da história, uma preocupação de alguns dos mais importantes autores. As obras intituladas Álbum para a Juventude de R. Schumann e P. Tchaikovsky são um perfeito exemplo da criação de peças acessíveis para alunos principiantes e mais avançados. O compositor, pianista, e pedagogo português Eurico Thomaz de Lima (1908–1989) criou Gradual. 28 Peças para a mocidade, um álbum organizado sequencialmente por critérios de dificuldade progressiva. Herdeiro de uma escola pianística de grande robustez, personalizada por A. Rey Colaço e J. Vianna da Motta, seus mestres no Conservatório de Lisboa, Thomaz de Lima incluiu em Gradual indicações exaustivas de dedilhação. Estas destinar-se-iam a guiar os jovens, proporcionando-lhes princípios sólidos desde uma fase precoce da sua aprendizagem. Neste artigo procura-se enfatizar a influência que figuras como A. Gilis, J. Barrozo Netto e J. Vianna da Motta exerceram nos métodos utilizados na conceção e organização de Gradual. Examina-se, paralelamente, dedilhações de Thomaz de Lima nas suas próprias composições e em obras que apresentava em concerto. Através de uma análise pormenorizada das minuciosas dedilhações para as vinte e oito peças do Gradual, verifica-se que estas revelam uma elevada consistência de princípios técnicos, lançando as bases para um crescimento harmonioso e sólido do jovem pianista.
Introdução

Published: October 2023

O presente número da revista Diacrítica tem a figura de Eurico Thomaz de Lima como referência e reúne um conjunto de estudos que se debruçam sobre o seu percurso artístico enquanto pianista, compositor e pedagogo. Herdeiro da tradição romântica centro-europeia do século XIX de influência germânica, Eurico, além de um intérprete virtuoso, revela nas suas obras para piano o gosto pelas raízes nacionais e uma linguagem pianística próxima do seu mestre Vianna da Motta (1868–1948). Alfredo Pinto (Sacavem), numa das suas Crónicas de Lisboa, publicadas semanalmente no Correio do Minho nas décadas de 20 e 30, afirma ter sido a última prova do curso de virtuosidade de Eurico Thomaz de Lima “um exame brilhantíssimo”. Curiosamente, o pianista pede-lhe que escreva no jornal local, que gostaria muito de tocar em Braga, o que viria a acontecer apenas muitos anos depois, quando passa a lecionar no conservatório da cidade.
A participação cívica e política dos jovens portugueses
Authors: Fernandes Filipe
Published: October 2023

De forma transversal entre os países europeus, o envolvimento político tradicional dos jovens é reduzido. A sua ligação a formas de participação formal das diversas democracias representativas do continente europeu é cada vez mais distante, registando-se este afastamento dos jovens face aos partidos políticos e o aumento das taxas de abstenção. Estes jovens têm optado por focar a sua participação através de modos mais informais, como manifestações pontuais, ativismo, assinatura de petições e, claro, aumento da participação com foco em temas sociais e políticos em plataformas digitais como as redes sociais. No entanto, os jovens portugueses não apresentam os mesmos níveis de envolvimento informal quando comparados com os seus congéneres europeus. Os portugueses tendem a ser menos participativos, espelhando uma problemática que se estende visivelmente a toda a população portuguesa, que, de forma mais formal ou informal, também participam pouco. O presente artigo procura compreender a participação cívica e política dos jovens portugueses. Realizaram-se 24 entrevistas e distribuiu-se um questionário ao qual se obteve 262 respostas. Esta amostra permitiu compreender que os jovens se sentem cada vez mais atraídos por modos de participação informal, desconfiando dos partidos políticos e das diferentes organizações. A sua participação pauta-se por ser momentânea, espontânea e direcionada para problemáticas particulares que constituem seus interesses e motivações.

A Recipe for Resilience: Case Study Examining Member Leaders in Online Communities (Preprint)
Authors: Skousen Tanner , Safadi Hani , Young Colleen D.
Published: October 2023

BACKGROUND

Although COVID-19 increased interest in online patient communities, it also created challenges to maintain moderation and desired outcomes. How can leaders in online communities resiliently address such unexpected challenges arising from external threats?

OBJECTIVE

This study examined the experience of one online patient community, Mayo Clinic Connect, to identify what challenges arise when faced with an external threat, what interventions are put in place to address those challenges, and what structures and processes effectively build resilience in community leaders.

METHODS

We use semi-structured interviews and observational data from Mayo Clinic Connect, a thriving online patient community, as a case study to answer our research questions. We used both a priori and inductive coding techniques to analyze our qualitative data.

RESULTS

In the case of Mayo Clinic Connect, the major challenge was losing a support team of staff moderators. As volunteer member leaders stepped up to fill this void, other challenges surfaced such as exhaustion and burnout of the volunteer member leaders. Amidst many interventions, an intervention of a bi-weekly meeting hosted by the community director was implemented to coach, support, and build capacity of the volunteer member group.

CONCLUSIONS

Online patient communities benefit from having a leadership core of volunteer members. When external shocks impact the community, these members act as slack resources to help resiliently sustain the community. However, when these members experience their own challenges, online communities should have a plan in place to provide support.
The Use of Medical Services for Low-Acuity Emergency Cases in Germany: Protocol for a Multicenter Observational Pilot Study (Preprint)
Authors: Nau Lara Maria , Laux Gunter , Altiner Attila , Szecsenyi Joachim , Leutgeb Rüdiger
Published: October 2023

BACKGROUND

The increasing number of requests for help for acutely ill patients and their management is a major problem in the health systems of many countries, but especially in Germany. Rescue coordination centers and ambulances in Germany are increasingly overloaded. As a result, rides as a part of rescue operations have been increasing in length for years, yet a relevant proportion of these operations represent low-acuity calls (LACs). The basic objective of this pilot study is the quantitative analysis of the potential misuse of requests to the rescue control center. Indications for alternative treatment options and how to handle these treatment options in nonacute, non–life-threatening health conditions, such as minor injuries or minor infectious diseases, will be assessed. The identification of these LACs is vital in order to prevent health care resources in emergency medical care becoming inadequate.

OBJECTIVE

The overarching goal of this study is to determine the percentage of unnecessary rescue missions on site and subsequently to obtain an impression of the paramedics’ assessment of alternative treatment options or alternative methods of rescue transportation.

METHODS

This will be an exploratory, noninterventional, cross-sectional study with a quantitative approach. The study is multicentric, with 21 ambulances in 12 different locations. The data for this study were collected via a questionnaire, newly developed for this study, for rescue personnel. Additionally, secondary data from the responsible control center will be linked and processed in an initial descriptive analysis. This descriptive analysis will form the basis for a subsequent variance analysis.

RESULTS

Data collection started as projected on September 18, 2023, and was ongoing until end of November 2023. We expect the documentation of several thousand rescue operations. We expect the following study results: (1) many unnecessary rescue operations, (2) immediate on-site assessment of correct care and treatment, and (3) patients’ reasons for calling a rescue coordination center.

CONCLUSIONS

To our knowledge, this is the first observational study in which acute rescue operations are recorded on site. The focus of this study is on the trained paramedics’ assessment of whether rescue operations are necessary or not. Additionally, alternative treatments, such as out-of-hours care service or primary care service, are shown for each individual case. The study also intends to cover the question of which factors are relevant and statistically significantly connected to the misuse of ambulances.

Published: October 2023

Entomopathogenic fungi are important component for regulation of pests in ecosystem. Isaria fumosorosea, as one of the entomopathogenic fungi, was reported to successfully controlled the outbreaks of forest defoliators attacked larch (Larix kaempferi) plantation in Furano, Japan and beech (Fagus crenata) forest in Hachimantai, Japan. Instead of semi-cultured method, in this paper, a culture-independent method based on DNA using qPCR was developed for specific detection and quantification of I. fumosorosea directly from soil DNA extract using specific primer. The primer IFU5821F/IFU6061R was designed and found to be the best primer pair for I. fumosorosea. Standard soil DNA was obtained with strong relationship and good fitting with five levels (R2= 0.989, E = 0.58). I. fumosorosea could not be detected from all soil samples which was possibility caused by low density of the fungi. The qPCR was likely a rapid and specific method to detect the fungus from soil.

ADAPTING CONTENT-BASED MATERIAL IN ESP COURSES: THE EXAMPLE OF DEBORAH POTTER’S HANDBOOK OF INDEPENDENT JOURNALISM
Authors: Lekaj Lubina Borka
Published: October 2023

The search for suitable teaching materials in ESP classes requires a lot of effort as available materials rarely satisfy all the specific needs of language learners in a particular subject area or syllabus. This is why some ESP teachers resort to adapting existing learning materials. This paper describes the motivation to adapt authentic content-based material for the use in English for Journalism courses within the academic study program of Journalism at the University of Zagreb. It outlines concrete techniques employed in adapting the Handbook of Independent Journalism written by Deborah Potter. These adapting techniques, primarily deletion and omitting, supplementation and rewriting of the original text, help learners to better identify specific morpho-syntactic features of English for Journalism, which is required by the syllabus. The main effect of material adaptation is better identification and acquisition of morpho-syntactic structures pertaining to English for Journalism. Overall, the adapted material re-engages learners with the content of the Handbook and thus enhances learning.
LANGUAGE LEARNING STRATEGIES AND ENGLISH PROFICIENCY OF SHIVAJI UNIVERSITY UNDERGRADUATE STUDENTS
Authors: Shinde Sunanda M , Shinde Mahesh B
Published: October 2023

The present study aimed to investigate the use of language learning strategies (LLS) by undergraduate students, the degree of use of language learning strategy included in the Oxford Taxonomy, and the relationship between the use of language learning strategies and English language proficiency. One hundred and forty-eight arts, commerce, science undergraduate students studying at various colleges affiliated to Shivaji University were the participants of the study. The results indicated that these students used LLS moderately to less; meta-cognitive strategies, social strategies, cognitive strategies, and memory strategies moderately; and compensation strategies and affective strategies were used less. The same correlation was found between the use of language learning strategies and English proficiency, which was indicated by students’ grades in proficiency tests. Overall, the results demonstrate that the use of language learning strategies used by the selected students varies depending upon the proficiency level. It was observed that less proficient students used fewer strategies and proficient students used them more.
Formas apelativas de segunda persona en entrevistas político-presidenciales mexicanas
Authors: Salgado López Melanie Del Carmen
Published: October 2023

A partir de lo sugerido en otros estudios (Cuenca, 2013; Cuenca Marín, 2015), analizaremos el uso de formas apelativas de segunda persona (vocativos, formas de tratamiento y formas pronominales en función de sujeto) que impactan en la construcción de las imágenes discursivas de los interlocutores, con el objetivo de establecer si los resultados aportan datos que permitan comprender con mayor precisión el género de la entrevista política presidencial en México. Los resultados muestran que dichas formas funcionan como una marca de transgresiones que reflejan la pugna por el poder en este dispositivo discursivo, impactan en el grado de transgresión del género y constituyen una manifestación lingüística que permite analizar la construcción del adversario político en el plano interaccional. Asimismo, es posible que las estrategias en el uso de las formas apelativas de segunda persona presenten patrones distintos con construcción del adversario correlacionados con los modelos presidenciales que encarnan los entrevistados, por lo que su análisis aportaría también al conocimiento del comportamiento de este género en el discurso político mexicano.
Modelling of the Optimal Impact of Photovoltaic Technology on a Sustainable Energetic Mix as Function of the Climate Conditions
Authors: Bechir Mahamat Habib , Aguera A. Lopez-
Published: October 2023

Abstract: The current global trend towards decarbonized energy systems forces countries to encourage the inclusion of renewable energy. Among the main challenges, intermittent electricity production due to the fluctuation of the solar resource. In addition, the variability of costs associated with the availability of the local resource may limit its contribution toward the demand side. The trend of these possible medium-term limitations of PV energy production associated to the capacity of solar resources has been estimated. Across the OSeMOSYS open-source software tool, two optimizations have been modeled, one merely economic and the other including energy sustainability estimators. As main result, the medium-long term PV contribution appears as residual for cold and moderate climates with medial day-to-day irradiation of less than 3.2 Peak Solar Hours. In addition, a trend towards saturation 40% of the energy coverage for highly irradiated areas is observed. This effect, associated with the non-availability of resources at night, can be mitigated by incorporating accumulation technologies. The inclusion of energy sustainability criteria enhances previous considerations.
Satisfacción con la enseñanza online en estudiantes universitarios: análisis estructural de una escala
Authors: Manrique-Millones Denisse , Lingán-Huamán Susana K. , Dominguez-Lara Sergio
Published: October 2023

El objetivo de esta investigación fue analizar la estructura interna y confiabilidad de la Student Satisfaction Survey (SSS) en estudiantes universitarios peruanos. Participaron 458 estudiantes (mujeres = 69.9 %; Medad = 27.76 años; DEedad = 4.41 años). La SSS se estudió bajo el análisis factorial confirmatorio (AFC) y el modelamiento exploratorio de ecuaciones estructurales (ESEM). Respecto a los resultados, el modelo original de cinco dimensiones obtuvo índices de ajuste favorables con ESEM, pero las dimensiones interacciones alumno-profesor e interacciones alumno-alumno se superponen entre sí, por lo que se valoró un modelo de cuatro dimensiones que presentó mejores evidencias psicométricas. La confiabilidad de las puntuaciones y de constructo presenta magnitudes aceptables. Se concluye que el SSS cuenta con propiedades psicométricas adecuadas.
A Study on the Determinants of Row House Sale price in Jeju-do
Authors:   Residential Environment Institute Of Korea, Yang Young Jun , Lee Seong Ho
Published: October 2023

In this study, the current status of houses in Jeju-do was examined, and the determinants of row house prices were analyzed using actual transaction price data of row houses traded from 2019 to 2022.
To summarize the analysis results focusing on Jeju-do, the price of small sized row house is higher than that of large sized. The higher the number of floors, the higher the price, and the higher the land area, the higher the price. Over time, prices have been shown to fall and then rise. The gross floor area, the number of parking per household, and the remaining building to land ratio have a positive effect on the price, and the larger the width of the road facing the land, the higher the price. By region, prices are high in the order of Eup·Myeon area of Seogwipo-si, Dong area of Jeju-si, Eup·Myeon area of Jeju-si and Dong area of Seogwipo-si, and by special-purpose area, residential area, green area, and control area are in the order. The higher the distance between elementary schools and the market, the higher the price, and the lower the distance between middle schools and government offices. One of the purposes of this study, the further away the row housing complex from the apartment complex, the lower the price.
In addition, in the empirical analysis that divided Jeju-do into four regions, it was confirmed that even the same variable could show different analysis results depending on the region.
A study on Humane Sensibility and Ecological Charactueristics of Post-Modern Architecture
Authors:   Residential Environment Institute Of Korea, Lee Seong-Go , Hwang Mi-Kyeong , Lee Sang-Hwa
Published: October 2023

There are two main trends in modern worldview. The main trend is pluralistic thinking that suggested the restoration of human identity and ecological thinking that emphasizes the coexistence of humans and nature for a sustainable society. Postmodernism includes stylistic values as well as timing meaning “after the present,” and it does not mean to escape from the present, but to realize simultaneous stratification of “past, present, future”and reproduce stratification of values such as “superior culture” and “minority and majority.” Postmodern architecture can be divided into periods from the 1960s to the present, such as exploration period (60s), introduction period (70s-80s), formation period (90s), and evolution period (2000s). The period of exploration attempted to shift from functionalistic thinking to pluralistic thinking in modern times, and the period of introduction reflected ecological thinking as well as human sensibility. As a result of analyzing 40 cases into 17 significant factors, they were divided into three groups: Group A, which mainly considers emotional design elements, Group B, which balances emotional and complex system science, and Group C. Group B includes the cases of Peter Eisenman, Norman Foster, Frank O. Gehry, Rem Koolhas and Enric Miracles, which have been considered major examples of modern architecture since the 1990s. Therefore, it can be seen that the main trends in modern architecture reflect human sensibility, which is the main motivation for the formation of postmodern architecture, and design elements considering complex system paradigms, fractals, and ecological characteristics. Therefore, the main trend of modern architecture is to realize design elements based on human sensibility and ecological characteristics in architecture by applying modern science and technology.
