Adaptive Training of the Mental Rotation Ability in an Immersive Virtual Environment

Virtual Reality (VR) opens new possibilities for the investigation and train-ing of Mental Rotational Ability (MRA), which is an important factor in the development of technical skills in several fields. Adaptive designs of MRA training environments realised by virtual technology could offer promising potentials and is investigated in this study. For the evaluation of effective-ness, the adaptive training environment is compared with the adequate ran-domised environment by assessing mental rotation ability in both conditions before and after training. As a dependent variable, the performance and its improvement in the virtual mental rotation test (VMRT), as well as the cog-nitive load, is measured. In addition, possible gender differences and their in-fluence on the training outcomes are determined. The study described here represents an innovative support option for MRA and provides an expandable empirical basis for VR-based adaptive trainings.
To Swab or Not to Swab? The Lesson Learned in Italy in the Early Stage of the COVID-19 Pandemic

Testing for the SARS-CoV-2 infection is critical for tracking the spread of the virus and controlling the transmission dynamics. In the early phase of the pandemic in Italy, the decentralized healthcare system allowed regions to adopt different testing strategies. The objective of this paper is to assess the impact of the extensive testing of symptomatic individuals and their contacts on the number of hospitalizations against a more stringent testing strategy limited to suspected cases with severe respiratory illness and an epidemiological link to a COVID-19 case. A Poisson regression modelling approach was adopted. In the first model developed, the cumulative daily number of positive cases and a temporal trend were considered as explanatory variables. In the second, the cumulative daily number of swabs was further added. The explanatory variable, given by the number of swabs over time, explained most of the observed differences in the number of hospitalizations between the two strategies. The percentage of the expected error dropped from 70% of the first, simpler model to 15%. Increasing testing to detect and isolate infected individuals in the early phase of an outbreak improves the capability to reduce the spread of serious infections, lessening the burden of hospitals.
Differences in Split Times between the Elite Breaststroke Swimmers

The aim of this research was to determine the differences between the finalists and semifinalists of the 2019 World Championships in the 100 m breaststroke. The total sample of subjects included in the study consisted of 23 male participants of the 2019 World Swimming Championships, who were divided into two groups. The first group consisted of finalists (24.75 ± 1.58 years; n = 8), and the second group of semifinalists (25.00 ± 3.38 years; n = 15). The results are taken from the official website of the International Swimming Federation (FINA). The variables analyzed in this study are: Split 1 first passing time of the 100 m breaststroke, Split 2 second passing time of the 100 m breaststroke, T100 total time of the 100 m breaststroke. All data were processed by statistical analysis one‐way ANOVA. The results of the research showed that there are no statistically significant differences between the final and semifinal groups in any of the examined variables, but there are evident numerical differences that are more pronounced in the Split 2 (F = 2.063; p = .166). Based on these results, it can be concluded that swimmers who excel in their abilities in the other 50 m of the race, or achieve better times in this segment of the race, will achieve a better final result.

Flexible Rigidity and Caring Distance: How Discretion Works in Compulsory Care

The aim of this article was to develop the understanding of discretion in compulsory care for youth and the influence of emotional aspects in developing a collective discretionary practice. The empirical material consists of group interviews with staff at these institutions. The theoretical concepts of emotional labour and emotional energy are used to understand discretion and face-to-face interaction in this specific setting. The results show how the staff navigate between rigidity and flexibility in order to uphold institutional rules, whilst also being able to meet youths’ different needs in specific situations in a personal, yet not private, manner. Professionalism is understood as providing a caring distance, in other words, a temporary emotional involvement with the youth. The staffs’ reasoning and understanding of their work show how to manage emotional labour in a setting where the youth can be seen as both dangerous and vulnerable. The emotional energy is primarily connected to the long-lasting relation amongst staff and not to the youth, and hence, it is of primary importance to form a shared collective discretionary practice.
Developmental Trajectory of Korean Adolescents Multicultural Receptivity Applying a Latent Growth Model

Introduction The purpose of this study was to analyze the developmental trajectory of Korean adolescents’ multicultural receptivity with a latent growth model. The study was performed using the data of 5,943 students (2,918 boys and 3,025 girls) who sincerely responded to all the questions used as variables in the data in the 2nd, 4th, and 6th years of the Korean Education Longitudinal Study: KELS 2013 by the Korean Educational Development Institute. The research results are as follows: First, adolescents’ multicultural receptivity insignificantly decreased, as they grew up. Second, peer relations, teacher relations, and community spirit in the early youth influenced the formation of early multicultural receptivity. Third, teacher relations had a positive relationship with multicultural receptivity and affected the change in multicultural receptivity later. Finally, community spirit had a positive relationship with multicultural receptivity, and as time passes, it affects the decrease of adolescents’ multicultural receptivity. In conclusion, this study has the significance that it investigated longitudinal changes in multicultural receptivity. The study reviewed and discussed the implications and limitations of the study based on the research results. According to the immigration statistics by the Korea Immigration Service, a Ministry of Justice-affiliated organization (2019), the number of foreigners was 2,367,607 persons in December 2018, 4.57% of the entire population, which is shown to experience increases each year. The number of multicultural families nationwide in 2018 was 319,000 households, and the number of members of the households was determined to be 964,000 persons. It is expected that the number of multicultural families in this region will reach one million soon (Ministry of Gender Equality & Family, 2019a). As immigrants entering and staying in the country for various purposes such as jobs, education, marriage and family formation, etc. grow in Korean society,

Narrative and analytical interplay in history texts: recalibrating the historical recount genre

ABSTRACT Based on Systemic Functional Linguistics (SFL) informed genre theory, this paper investigates the interplay between narrative and analytical representations of the past in texts used for history-educational purposes. In this paper, it is argued that the role of narrative merits further attention in history genre descriptions. Thirteen history texts, selected from a lower-secondary history-instructional unit about European colonization, are examined. The examination of stages, narrative elements, and the way historical significance is expressed in these texts arrives at a re-calibration of the historical recount genre suggesting four distinct historical recount types with different configurations of a narrative-analytical interplay. The findings have implications for our understanding of the role of narrative elements in history texts, and further for genre-based approaches to instruction that concern reading and writing history texts.
Elites and Culture: Social Profiles in the Cultivated Population

Since the 1990s, the central references of the sociology of cultural practices have been the theoretical frameworks developed by Pierre Bourdieu and Richard A. Peterson around the concepts of distinction and omnivorousness. This article is based on these frameworks; it revises them together with those of Donnat and Lahire and postulates that the terms of cultural classification and especially those of the upper classes (distinguished and omnivorous) require revision. The article also claims that there are diverse socio-cultural profiles due to the fact that there is never a single logic of differentiation of tastes, and that the results of the present research demand a new conceptual framework capable of showing the operation of diverse logics of differentiation and hierarchy. In order to do this, an analysis of the socio-cultural profiles of the cultivated groups in Spanish society is carried out on the data obtained from the Survey of Cultural Habits and Practices in Spain 2018/19. This work proves the existence of three types of cultivated population – classical, modern and syncretic – with notable differences in their cultural interests and practices, as well as in their underlying sociodemographic features and aesthetic logics, and concludes by posing the need to delve into the latter in what it defines as the study of cultural practice regimes.
Mechanical Activation Of Valvular Interstitial Cell Phenotype

During heart valve remodeling, and in many disease states, valvular interstitial cells (VICs) shift to an activated myofibroblast phenotype which is characterized by enhanced synthetic and contractile activity. Pronounced alpha smooth muscle actin (αSMA)containing stress fibers, the hallmark of activated myofibroblasts, are also observed when VICs are placed under tension due to altered mechanical loading in vivo or during in vitro culture on stiff substrates or under high mechanical loads and in the presence of transforming growth factor-beta1 (TGF-β1). The work presented herein describes three distinct model systems for application of controlled mechanical environment to VICs cultured in vitro. The first system uses polyacrylamide (PA) gels of defined stiffness to evaluate the response of VICs over a large range of stiffness levels and TGF-β1 concentration. The second system controls the boundary stiffness of cell-populated gels using springs of defined stiffness. The third system cyclically stretches soft or stiff twodimensional (2D) gels while cells are cultured on the gel surface as it is deformed. Through the use of these model systems, we have found that the level of 2D stiffness required to maintain the quiescent VIC phenotype is potentially too low for a material to both act as matrix to support cell growth in the non-activated state and also to withstand the mechanical loading that occurs during the cardiac cycle. Further, we found that increasing the boundary stiffness on a three-dimensional (3D) cell populated collagen gel resulted in increased cellular contractile forces, αSMA expression, and collagen gel (material) stiffness. Finally, VIC morphology is significantly altered in response to
Reduction of MOS interfacial states between β-Ga2O3 and Al2O3 insulator by self-reaction etching with Ga flux

In this Letter, self-reaction etching (SRE) with Ga flux demonstrates the capability of eliminating surface contaminations and damage, as well as improving the electrical characteristics of the interface between monoclinic gallium oxide (β-Ga2O3) and the insulator. Compared to post-tetramethyl ammonium hydroxide wet chemical treatment, SRE is a low damage repair method that effectively removes surface contaminants introduced during previous inductively coupled plasma etching of β-Ga2O3 without surface damage. As a consequence, the surface band bending on the β-Ga2O3 surface decreased as demonstrated by the core-level peak shifts of x-ray photoemission spectroscopy, which indicated fewer negative charges remained on the surface. Furthermore, the interface state density (Dit) between β-Ga2O3 and an Al2O3 insulator was determined by using high-temperature conductance and photoassisted C–V measurements. The Dit dropped significantly for samples treated by SRE as compared with other treatments. These results suggested that SRE is an attractive etching candidate for future Ga2O3 power device fabrication.
ANALISIS KEMANDIRIAN BELAJAR SISWA MELALUI PEMBELAJARAN DARING PADA MATA PELAJARAN MATEMATIKA

This study aims to analyze the independent learning of students in mathematics through e-learning in class IX SMP Negeri 10 Gorontalo. This research is a descriptive research type, with a population of all class IX students of SMP Negeri 10 Gorontalo, totaling 101 students, consisting of 4 classes. The sample in the study was 20 people using a simple random sampling technique. The data obtained were obtained from student learning independence questionnaire sheets, as well as interviews with students related to students' learning independence in mathematics through e-learning. Based on the results of the research and discussion that the researcher has described in the previous chapter, that the learning independence of students in mathematics through e-learning is seen based on five indicators of learning independence divided into three categories namely high, medium and low categories. There are 4 high category students with an answer percentage of 20%. Second, there are 13 students belonging to the medium category with an answer percentage of 65%. Third, there are 3 students in the low category with an answer percentage of 15%. Of the three categories, in general, students only fulfill part of the indicators of learning independence measured in this study. So based on this, it can be concluded that the independent learning of students in mathematics through e-learning in class IX SMP Negeri 10 Gorontalo is still classified as moderate, so it needs to be improved.
Spatial Changes in Late Quaternary Slip Rates Along the Gyaring Co Fault: Implications for Strain Partitioning and Deformation Modes in Central Tibet

Studying the slip rate along major strike‐slip faults is critical to understanding the deformation and kinematics in continental collision zones. The Gyaring Co fault was previously regarded as a segment of the southern boundary of eastward extrusion in central Tibet, and its eastern segment was linked to the Xainza rift. However, the spatial distribution of its slip rates is poorly constrained, which limits our knowledge about how deformation is partitioned between strike‐slip and normal faults in central Tibet. Here, we used optically stimulated luminescence dating to determine the ages of displaced landforms (alluvial fans, lake shorelines, and river terraces) along the Gyaring Co fault. The results demonstrate a southeastward decrease in the late Quaternary slip rate from 2–3 mm/yr to 0.5–1.0 mm/yr over a distance of ∼130 km. Although the slip rate of the middle‐west segment of the Gyaring Co fault seems to have decreased slightly (20%) at ∼10 ka, it remained relatively stable during the late Quaternary. Regional analysis suggested that the Gyaring Co fault is kinematically compatible with the Xainza rift and probably has accelerated rift extension in its northern part since the middle Miocene. This northward‐increasing extension rate may accommodate more than half of the observed strain‐rate gradient along the Gyaring Co fault. The difference observed in strain rate requires a strain of ∼1 × 10−8 per year, comparable with the average present‐day strain rate of the Tibetan Plateau. The Gyaring Co fault separates the crustal blocks that are also deforming internally, suggesting distributed deformation in central Tibet.
Utility of Neutrophil-Lymphocyte Ratio (NLR) as an Indicator of Disease Severity and Prognostic Marker among Patients with Covid-19 Infection in a Tertiary Care Centre in Bangalore – A Retrospective Study

BACKGROUND The infection caused due to novel coronavirus 2 can cause wide spectrum of disease from asymptomatic mild disease to life threatening disease. The widespread inflammation is most likely the cause of the adverse outcomes. There are numerous markers of the inflammation which are used to identify the severity and prognosis of the disease. Neutrophil lymphocyte ratio (NLR) is one such marker which is easily available and feasible in all the hospital settings. This study intended to evaluate the NLR as a marker of disease severity and prognosis, in those with Covid-19. METHODS This was a retrospective study to determine the utility of NLR as a marker of severity and prognosis among patients with Covid disease. Medical records of 60 patients admitted with mild to moderate Covid-19 disease were reviewed and relevant data was retrieved. The NLR at admission and 72 hours later was noted. High resolution computerised tomography was done and computerised tomography severity score (CT-SS) was calculated. The outcomes of these patients were noted. RESULTS Mean NLR at admission in mild disease was 5.6 and in moderate disease was 9.2. This difference was found to be statistically significant. It was also seen that NLR had a positive co-relation with CT severity score, duration of hospital stay, Creactive protein (CRP) and D-dimer. For predicting mortality, NLR with cut off of 6.6 had a sensitivity of 100 % and a specificity of 66.07 %. CRP with cut off of 6.8 had sensitivity of 100 %, specificity of 76.79 %. D-dimer with cut off of 1.6 had specificity of 78.58 %. For predicting severity, NLR with cut off of 6.6 had sensitivity of 75 % and specificity of 80 %. CRP with cut off of 7.9 had sensitivity of 65 % and specificity of 100 %. D-dimer with cut off of 1.3, had sensitivity of 90 % and specificity of 97.5 %. CONCLUSIONS The study shows that neutrophil–lymphocyte ratio is a good indicator of disease severity and has prognostic significance in Covid-19. There is a positive correlation with high-resolution computed tomography (HRCT) chest score and other markers of inflammation among patients with Covid-19. Serial monitoring of NLR can be utilised as a surrogate to HRCT chest to determine disease severity whenever the latter is not available. This can ensure early intervention and help prevent mortality. KEYWORDS Neutrophil-Lymphocyte Ratio, Severity of Covid
Numerical implementation of wave friction factor into the 1D tsunami shallow water equation model

ABSTRACT In most of the current conventional tsunami numerical models, the steady flow friction law has been widely used to access the tsunami-induced bottom shear stress. However, according to our previous theoretical investigation showed that in almost the entire model domain from the tsunami source to the nearshore area, the tsunami-induced bottom boundary layer behaves like a wave boundary layer, rather than a quasi-steady flow boundary layer. The present study aims to develop a numerical method for tsunami simulation that elaborates a wave friction factor by implementing a correction method proposed by authors' previous work into the conventional 1D shallow water equation. As a result, the new method provides similar results to the original Manning method regarding the water level and the tsunami-induced velocity. However, the bottom shear stress estimated by the new method is higher than that from the Manning method over the entire computational domain. The transition locations from the wave friction zone to the steady friction zone are found at the water depth around 5 m under the present computational condition.
