Published: March 2021

A flexible-shaped ultrasonic array probe that can be used in a high magnetic field environment in an MRI gantry has been developed. Given that this probe can be fixed according to the shape of the skull’s surface, it is particularly applicable for imaging in the brain. To perform ultrasonic beamforming using a bent probe, it is necessary to measure the bent shape. Therefore, in this research, the curvature of the probe was estimated using MRI. A phantom with ellipse surface close to the shape of a skull was created using a 3D printer. The probe was arranged along the phantom surface to perform MRI and ultrasonic beamforming. The ultrasonic array transducer had 192 elements made from 1-3 composite piezoelectric materials with an element spacing of 0.3 mm. Eight MR position markers were attached to the probe in parallel in two rows of four each, with the array transducer in between. The delay time of each element in dynamic focusing for reception was calculated from its position estimated by the curvature of the probe. To evaluate the feasibility of this method, a B-mode image of 0.98 mm-diameter-thread targets placed in water was generated. The beam width at half maximum of the echo peak in the lateral direction from the thread target set up near the transmission focal point was calculated based on the B-mode image. It was found that the beam width of 1.32 mm in the proposed method, which was close to the thread diameter, whereas that was 4.38 mm in the conventional method that did not consider the bending of the probe. Consequently, the proposed beamforming technique is feasible for ultrasonic imaging through an arbitrary curved surface. Practical applications with a head phantom mimicking skull and cerebral tissue are expected.

New free electron lasers, such as SLAC’s LCLS-II, will provide unique scientific imaging opportunities. In order to fully utilize these facilities, we need to develop detectors with shallow entrance windows that will enable detection of soft x-rays from 250 eV to 1.5 KeV. Achieving adequately shallow entrance windows is challenging because the high temperature anneal needed to activate the dopant also drives the dopant profile deeper, growing the region that is insensitive to soft x-rays. A new microwave annealing technology provides an efficient way to achieve shallow entrance windows in fully depleted high-resistivity silicon sensors. The microwave anneal technique can activate dopants at low substrate temperature, with minimal dopant diffusion, and can be used to fabricate both n-type and p-type entrance windows. SRP and SIMS measurements were used to verify dopant activation with negligible dopant diffusion. We then applied the microwave anneal process to a planar sensor wafer, using the new process to create the backside diode contact. Electrical test of the resulting sensors shows good reverse bias characteristics. The sensors have been bump-bonded to a read-out ASIC and used successfully to measure an Fe-55 x-ray spectrum. Process and device simulations were performed to characterize the quantum efficiency of the entrance window for soft x-rays. This technique is useful for other sensor applications requiring a shallow entrance window, including detectors for UV photons, low energy ions and low energy electrons.

Due to the COVID-19 pandemic, cities and states adopted social distancing, social isolation, or quarantine measurements to slow the transmission of the disease. Negative mental health outcomes including depression and anxiety have been associated with social distancing or social isolation. The purpose of the present study was to examine changes in psychological health and physical activity over an 8 week period under social distancing policies during the COVID-19 pandemic.Methods: Ninety (73.3% female; age 32.04 ± 11.33) individuals participated in this study. Qualifying participants answered questions using an online survey regarding their loneliness, depressive symptoms, anxiety symptoms, mood state, and physical activity over four time points each lasting two weeks.Results: Symptoms of depression and state anxiety were increased in the population when compared to nationwide statistics from before the COVID-19 pandemic. Time point 2, ~1 month into social isolation, showed the most significant effects on mental health. During this time point, 100% of the participants showed symptoms of depression. There were no significant changes in physical activity over the 8 weeks. Loneliness, depressive symptoms, fatigue, and mood state were negatively associated with participation in physical activity. Vigor and state anxiety were associated with participation in physical activity.Conclusion: Social isolation and social distancing practices have had a negative effect on depression, anxiety, and mood over time. It appeared that depressive symptoms and total mood disturbance was elevated during time point two. Depressive symptoms were much higher than average compared to previous epidemiological data. Physical activity amount did not change over time but was associated with poor mental health.

Background: Dialogic Literary Gatherings (DLG) are evidence-based interventions implemented in very diverse educational and health settings. The main elements that make DLG a co-creation intervention and promote health during the COVID-19 crisis lockdown are presented. This study focuses on the case of a DLG that is being promoted by an adult school in the city of Barcelona.Methods: This qualitative study was conducted using a communicative approach. Seven in-depth interviews with participants in the online DLG have been conducted. Five of them are women without higher education ranging from 56 to 85 years old and two are educators of this school.Results: The main results are 2-fold. First, the factors that make DLG a co-creation intervention, such as egalitarian dialogue and dialogical creation of knowledge in the decision-making process, are found. Second, the results show how DLG is contributing to creating a supportive environment that breaks the social isolation of confinement and improving the participants' psychological and social well-being.Conclusions: The findings from this study contribute to generating knowledge about a co-creation process between adult education participants and educators in education and health promotion during the COVID-19 lockdown, which could be replicated in other contexts.

Abstract
The enhancement of high-order surface acoustic wave (SAW) harmonics by increasing the metallization ratio was theoretically and experimentally investigated in high-performance bonded dissimilar-material structures. The simulation using a finite element method for 36°Y-cut X-propagating LiTaO3 (36°YX-LT)/AT-cut 90°X-propagating quartz (AT90°X-quartz) and 27°YX-LiNbO3/AT90°X-quartz was performed by setting the metallization ratio of the interdigital transducer to a/p = 0.8 (a: electrode width, p: pitch), and the LT and LN thin-plate thicknesses to h/λ = 0.05 (λ: wavelength) and 0.1, respectively. The fractional bandwidths for 36°YX-LT/AT90°X-quartz and 27°YX-LN/AT90°X-quartz were obtained to be 1.6% and 4.0%, respectively, which were larger than those for single LT and LN. For a leaky SAW (LSAW) resonator with a/p = 0.8 fabricated on 36°YX-LT/AT0°X-quartz, the resonance properties and temperature coefficient of frequency of LSAW fundamental waves and harmonics were measured. The measured fractional bandwidth increased from 0.8% to 1.4% for single LT.
幻の春の声. 近現代日本文学における「亀鳴く」/ The illusory voice of the spring: the motif of ‘crying turtle’ in modern and contemporary Japanese literarure
Authors: Cucinelli Diego 
Published: March 2021

The turtle (kame) is of great importance in East Asian culture and it is seen as a supernatural creature. In Japanese literature, we can find examples of the turtle in works dating back to the Nara period, such as Tangokuni fudoki and Nihonshoki. Just like the crane, the turtle is a symbol of longevity. However, from the Kamakura period a new and unique interpretation of the turtle as the “singing/crying turtle” makes its appearance. Of this topos, known as kame naku, we can find only very few examples in literature until the Meiji era and the most known are the waka anthologies Shinsen waka rokujō and Fuboku wakashō, and Kyokutei Bakin’s kigo collection Haikai saijiki shiorigusa. However, from the beginning of the modern age, kame naku has been used by many poets as a kigo connected to spring and its frequency has hugely increased. After the war, it began to appear not only in poetry but also in novels and essays. The best known examples of this being Mishima Yukio’s short novel Chūsei, Uchida Hyakken’s essay Kame naku ya, Kawakami Hiromi’s work Oboreru. Using kame naku as a keyword, in this paper we will analyze the attitudes and approaches of modern and contemporary poets and novelists toward the topos.

Published: March 2021

La repercusión de la COVID 19 en la sociedad precisa el estudio de diversidad de factores, entre ellos los ambientales, los cuales hacen referencia al entorno o contexto donde se debe tener en cuenta la estimulación, la afectividad y las normas de crianza desde una edad temprana. Los factores culturales y socioeconómicos contemplan el desarrollo de cada niño, influenciado por el entorno social al que pertenece y la cultura de sus familias, valores sociales, religiosos, morales, éticos y estéticos. Cuando una persona ha vivido en sociedad y por razones extremas se encuentra privada de las relaciones con los demás, teniendo que vivir totalmente aislada, ésta asume su vida siguiendo los patrones que la sociedad le enseñó. En el subsistema de la sociedad se requiere la colaboración de todos sus miembros mediante una variedad de trabajos que hagan posible el desarrollo social y familiar para hacer más llevadero el aislamiento actual ocasionado por la pandemia. Este articulo toca las fibras de la sociedad guajira y sus raíces en las dimensiones socio afectiva, socioeducativa, socioeconómica y cultural, así como el rol familiar de la región.

Implication Statement
Institutions have been faced with the unique challenge of continuing to deliver medical education to students in a COVID-19 environment.1,2 Clinical skills teaching must be adapted to the pandemic environment, which begins with retaining Volunteer Patient (VP) engagement to facilitate the development of students’ patient care aptitudes. The number of available VPs has been significantly reduced by the pandemic. We propose actionable solutions to recruit, engage, and retain VPs that can be easily adopted at any site. The SLIM-COVID framework can assist programs in altering curricula to deliver clinical skills with patient involvement in a pandemic environment.

VERBS OF MOVEMENT AS INDICATORS OF SENSE RELATIONS IN DESCRIPTIVE PREDICATES (A FRAGMENT OF A LINGUODIDACTIC MODEL OF RUSSIAN GRAMMAR)
Authors: Панков Ф.И. , Пищурова А.О. 
Published: March 2021

Одна из лакун лингводидактической модели русской грамматики – описательные предикаты, неотъемлемой составной частью которых являются показатели смысловых отношений – экспликаторы. Статья представляет собой опыт анализа глаголов движения во вторичной семантической функции в качестве экспликаторов. В статье рассмотрена полевая структура категории описательных предикатов с глаголами движения, включающая ядро, приядерную зону и периферию. Языковой материал показал, что в основе образования описательных предикатов с глаголами движения лежит семантика однословного коррелята. Корректное использование глаголов движения в составе описательных предикатов позволит инофонам, с одной стороны, успешно решить свои коммуникативные потребности, а с другой – сделать речь более образной и эмоциональной.
One of the lacunae of the linguodidactic model of Russian grammar is descriptive predicates, an integral part of which are indicators of semantic relations – explicators. The article presents the experience of analyzing verbs of movement in the secondary semantic function as explicators. The article considers the field structure of the category of descriptive predicates with verbs of movement, including the core, the prionuclear zone and the periphery. The language material has showed that the formation of descriptive predicates with verbs of movement is based on the semantics of the one-word correlate. Correct use of verbs of movement as part of descriptive predicates will allow foreign speakers, on the one hand, to successfully solve their communication needs, and on the other hand, to make speech more imaginative and emotional.
Penerapan Metode Balanced Scorecard dan Analytical Hierarcy Process (AHP) Dalam Penentuan Karyawan Berprestasi (Studi Kasus : Kantor Pertanahan Kota Pekanbaru)

Published: March 2021

The National Land Agency (abbreviated BPN in Indonesian) is a non-ministerial government institution that is under and responsible to the President and led by the Head (in accordance with Presidential
Decree No. 63 of 2013). The problems that occur at the Pekanbaru Land Office in determining outstanding employees are only seen based on the results of the work they do, not based on the criteria for each employee. Therefore, this study was conducted to provide application in determining outstanding employees with more detailed results based on the criteria of each employee using several methods,
including the Balanced Scorecard method and the Analytical Hierarchy Process (AHP). Based on the
research results, it is known that based on the Balanced Scorecard method, the criteria to be used are Comprehension, Accuracy, Craft, and Discipline with the same highest value, namely 12.25. After that, each employee was assessed based on the criteria using the Analytical Hierarchy Process (AHP) method with the highest score being DHEA with a value of 0.301.

Abstract
Star formation in galaxies is a hierarchical process with a wide range of scales, from smaller clusters to larger stellar complexes. Here, we present an ultra-violet imaging study of the nearby flocculent spiral galaxy NGC 7793, observed using the Ultra-Violet Imaging Telescope (UVIT). We find that the disk scale length estimated in Far-UV (2.64 ± 0.16 kpc) is larger than that in Near-UV (2.21 ± 0.21 Kpc) and optical (1.08 Kpc), which supports the inside-out growth scenario of the galaxy disk. The star-forming UV disk is also found to be contained within the extent of H i gas, with a column density greater than 1021 cm−2. With the spatial resolution of UVIT (1 pixel ∼ 6.8 pc), we identified 2046 young star-forming clumps in the galaxy with radii between ∼12 and 70 pc, which matches well with the size of giant molecular clouds (GMCs) detected in the galaxy. Around 61% of the regions identified in our study are younger than 20 Myr, which points to a recent enhancement in star formation across the galaxy. We also note that the youngest star-forming regions, with an age of <10 Myr, distinctly trace the flocculent arms of the galaxy. The estimated mass of the clumps covers a range between 103 and 106
M
⊙. We notice a gradient in the mass distribution of identified clumps along the spiral arms. We also study the nuclear star cluster of the galaxy, finding that the stellar populations in the cluster outskirts are younger than the inner part.
