The purpose of this study is to design and develop a multimedia web-based constructivist learning application known as WebOPAC Self Training Tool with Guided Exploration (WSTTG) which is expected to train and access individual’s information literacy skills. This tool has been designed and developed according to the constructivist instructional design theories and constructivist instructional development model. The process design consists of four level processes which were component design, single path prototype, alpha version and beta version. The development process ended with four activities which were summative evaluation, final packaging, diffusion and adoption. Throughout the design and development process, there were two instructional designers and two subject matter experts were participated to review and evaluate the design components of the WSTTG. Three potential learners were also participated to evaluate the beta version prototype whether it is appropriately apply to their learning context. The repetition of reviewing the alpha and beta version prototypes lasted when there were no comments found during the final evaluation. Overall, all experts and learners were satisfied with the interface, surface characteristics, scenario, and instructional strategies used in the prototype after consideration on comments and suggestions have been made accordingly. This tool was recommended to be commercialized as an instructional strategy for library orientation program and to be used by both the librarians and library users for WebOPAC teaching and learning purposes. The design and development of this tool could be a guideline to future instructional designers, web developers and e-learning content specialist in developing a multimedia web-based constructivist application in various fields.

Fortified Fluconazole Eyedrops for Treatment of Culvularia Corneal Ulcer
Authors: Reza Arlas Muhammad , Petty Purwanita
Published: March 2021

Abstract

Introduction. Fungal keratitis is less common than bacterial keratitis, generally representing less than 5%–10% of corneal infections in reported clinical series in the United States. But in developing countries (Ghana, India, China) it accounts for more than 90% of the cases. Corneal trauma by plant or vegetative material is the leading risk factor for fungal keratitis. One or more topical antifungals are usually administered with systemic support of oral antifungals. The most common classes of antifungal used for medical therapy include the polyenes, azoles, and the echinocandins.

Case Illustration. A 47-year-old male presented with a widening white patch on his left eye since 4 days before coming to our hospital. The left eye was injured by wood flakes 3 weeks ago. He felt a sore, red, watery left eye and blurred vision. He washed his eyes with betel leaf water. His left eye visual acuity was 1/60 and not improved with pinhole. There were blepharospasm, ciliary and conjunctival injection. Corneal examination showed a cloudy cornea, a central corneal defect sized 8x6 mm with an irregular margin, 2/3 to stromal depth, infiltrate, satellite lesion, and positive fluorescein staining at the defect margin. KOH examination demonstrated hyphae. The culture test of left corneal discharge identified a fungi species (Curvularia sp). We prescribed fortified fluconazole eye drops in combination with supportive therapy for 2.5 months. This regimen showed a significant increase in visual acuity to 6/30 with pinhole improvement of 6/21 in the left eye.

Discussion. Imidazole acts by inhibiting ergosterol biosynthesis of the fungal cell wall, through action on the cytochrome P450-dependent enzyme. This leads to cell membrane destabilization and leakage. Curvularia sp belongs to the family of dematiaceous fungi. Its clinical manifestations include raised lesions and feathery edges; hypopyon rarely occurs, and the prognosis is quite good. Fluconazole (2 mg/ml) is available for injection and is a well-tolerated eye drop. The intravenous injection can be used as a topical treatment and can be given subconjunctivally at the same concentration.

Conclusions. Fortified fluconazole eyedrops (2 mg/ml) can become an alternative and additional therapy for deep fungal keratitis, especially for Curvularia sp.

Poesía e Historia. La conciencia expandida del ultimo Celaya
Authors: Scarano Laura
Published: March 2021

En la obra de Gabriel Celaya (1911-1991) asistimos a una conjunción singular de poesía e historia, que se despliega en fases diversas y complementarias, apoyadas en una sólida meditación autorreferencial. Abordaremos aquí las flexiones finales de su obra poética a partir de la década del 70 hasta su muerte, superada la dictadura franquista y libre de las coerciones de la censura. Veremos cómo profundiza aquella matriz de resistencia e inconformismo, afianzando vectores vitalistas como la concepción colectiva de la identidad, la implicación social y cósmica de la poesía, su virtualidad oral, etc.
Una mesa familiar imposible. La versión fílmica de "Esperando la carroza"
Authors: Sala Jorge
Published: March 2021

Entre las producciones filmadas durante la transición democrática argentina (1983-1989) Esperando la carroza constituye un caso singular debido a su éxito alcanzado a lo largo del tiempo. A partir de los interrogantes que genera su repercusión pública, el artículo examina el lugar de la mesa familiar en esta película, asumiendo a este objeto desde una perspectiva doble: 1) como un dispositivo que funciona al mismo tiempo como leitmotiv, como desencadenante dramático y como factor de aglutinación de lo público y lo privado; 2) entendiendo este como un elemento clave que posibilita reconstruir una genealogía de representaciones teatrales y cinematográficas que aportan un plus de sentido a su figuración en la pantalla. A través del análisis textual, el ensayo se propone dar cuenta de ambos problemas, los que permitirán situar simultáneamente a esta película dentro de su marco epocal, viendo también sus derivaciones futuras.
Japanese University Student Experiences with Internships in Southeast Asia
Authors: Nowlan Andrew
Published: March 2021

The purpose of this article is to examine the personal, academic, and professional
experiences of five Japanese university students who did short-term academic
internships in three southeast Asian nations. Since students in Japan often
associate international opportunities with inner-circle English-speaking
countries (e.g. the United States of America or the United Kingdom), this article
highlights the perceived benefits of choosing Southeast Asia as an educational
destination. In limited published studies, researchers have revealed that
Japanese students may gravitate towards Southeast Asia for multilingual
language learning opportunities, lower perceived discrimination, and reduced
financial costs. This article provides additional insight into the discerned
advantages and disadvantages. Data for this qualitative exploratory study
include weekly written reflections from students who were in southeast Asian
countries from late 2018 to early 2019, followed by a focus group and individual
questionnaires in the months following the participants’ return to Japan. Based
on thematic analysis of self-reporting, results suggest that the participants found
value in their experiences due to the (a) proximity and costs involved, (b)
comfort with using a non-native variety of English, and (c) development of
intercultural competences and soft skills. More specifically, participants felt that
their experiences were less financially burdensome on parents, compared to
similar experiences in inner-circle destinations. Also, participants reported
feeling comfortable using English as a lingua franca, despite communicating in
lower-context environments. This, in turn, contributed to the development of
their adaptation, negotiation, and communicative skills. If higher education
stakeholders and recruiters can better promote the educational experiences of
Japanese university students in Southeast Asia, such as those featured in this
article, then it is possible that access and participation may increase in the future.

Unpredictive linguistic verbal cues accelerate congruent visual targets into awareness in a breaking continuous flash suppression paradigm
Authors: Paffen Chris L. E. , Sahakian Andre , Struiksma Marijn E. , Van der Stigchel Stefan
Published: March 2021

One of the most influential ideas within the domain of cognition is that of embodied cognition, in which the experienced world is the result of an interplay between an organism’s physiology, sensorimotor system, and its environment. An aspect of this idea is that linguistic information activates sensory representations automatically. For example, hearing the word ‘red’ would automatically activate sensory representations of this color. But does linguistic information prioritize access to awareness of congruent visual information? Here, we show that linguistic verbal cues accelerate matching visual targets into awareness by using a breaking continuous flash suppression paradigm. In a speeded reaction time task, observers heard spoken color labels (e.g., red) followed by colored targets that were either congruent (red), incongruent (green), or neutral (a neutral noncolor word) with respect to the labels. Importantly, and in contrast to previous studies investigating a similar question, the incidence of congruent trials was not higher than that of incongruent trials. Our results show that RTs were selectively shortened for congruent verbal–visual pairings, and that this shortening occurred over a wide range of cue–target intervals. We suggest that linguistic verbal information preactivates sensory representations, so that hearing the word ‘red’ preactivates (visual) sensory information internally.
Logical minimization for combinatorial structure in FPGA
Authors: Bibilo P. N. , Lankevich Yu. Yu. , Romanov V. I.
Published: March 2021

The paper describes the research results of application efficiency of minimization programs of functional descriptions of combinatorial logic blocks, which are included in digital devices projects that are implemented in FPGA. Programs are designed for shared and separated function minimization in a disjunctive normal form (DNF) class and minimization of multilevel representations of fully defined Boolean functions based on Shannon expansion with finding equal and inverse cofactors. The graphical form of such representations is widely known as binary decision diagrams (BDD). For technological mapping the program of "enlargement" of obtained Shannon expansion formulas was applied in a way that each of them depends on a limited number of k input variables and can be implemented on one LUT-k – a programmable unit of FPGA with k input variables. It is shown that a preliminary logic minimization, which is performed on the domestic programs, allows improving design results of foreign CAD systems such as Leonardo Spectrum (Mentor Graphics), ISE (Integrated System Environment) Design Suite and Vivado (Xilinx). The experiments were performed for FPGA families’ Virtex-II PRO, Virtex-5 and Artix-7 (Xilinx) on standard threads of industrial examples, which define both DNF systems of Boolean functions and systems represented as interconnected logical equations.
Algorithm for preliminary processing of charge coupled devices array data based on the adaptive Wiener filter
Authors: Litvinovich Hl. S. , Bruchkouski I. I.
Published: March 2021

The researcher should choose the modes of recording spectra which allow to achieve the highest accuracy of spectral measurements in remote sensing systems. When registering a signal from aircraft which provide maximum coverage of the studied area, it is important to obtain a signal with the maximum signal-to- noise ratio in a minimum time, since the accumulation of spectra samples for averaging is impossible. The paper presents the experimental results of determining the noise components (readout noise, photon, electronic shot, pattern noise) for a monochrome uncooled CCD-line detector Toshiba TCD1304DG (CCD – charge-coupled devices) with various conditions of spectrum registration: detector temperature, exposition. Obtained dependences of the noise components make it possible to estimate the noise level for well-known conditions of spectra registration. The algorithm for processing CCD data based on an adaptive Wiener filter is proposed to increase the signal-to-noise ratio by using a priori information about the statistical parameters of the noise components. Such approach has allowed to increase the signal-to-noise ratio of sky spectral brightness by 4–9 dB for exposure times. The practical application of the algorithm has reduced the uncertainty in the vegetation index NDVI by 1.5 times when recording the reflection spectra of vegetation from the aircraft in the nadir measurement geometry.

The evolution of keel flowers within Fabaceae, Polygalaceae and some other clades of angiosperms is attributed to skilled and strong bees. However, whether this is true or not, is still an open question. Therefore, the literature is surveyed for the Hymenopteran pollinators of keel flowers, for 119 sources and for 112 species, six genera and two tribes for five characters which are the size of the flowers, Hymenopteran flower visitors/pollinators, size of the Hymenopteran pollinators, pollen and nectar robbers/thieves and size of the Hymenopteran thieves/robbers. The results suggest that Fabales keel flowers are mainly pollinated by long-tongued bees, from Apidae and Megachilidae families; and the most common pollinators of the keel flowers are small Megachile and Osmia; medium-sized Apis, Anthophora and Eucera; and large Xylocopa, Bombus and Centris. While the literature suggests that keel flowers are pollinated by skilled and strong bees, the results of the current review have shown that this is not the whole case in terms of flower size and bee size. There is no difference between pollinator diversity and flower size. While floral robbers/thieves are mostly up to 2 cm, among them honey-bees (Apis mellifera) both pollinate and rob the keel flowers. Keel flowers of Polygalaceae and other angiosperm lineages are somehow similar to the keel flowers of Papilionoideae.

Habitatlar üzerinde devam eden baskı ile artan nüfus, endüstriyel ve kentsel gelişim, artan tarım uygulamaları, istilacı türlerin artan tehditleri ve iklim değişikliğinin etkileri ile birlikte bugün tehlike altında olmayan birçok tür, gelecekte büyük olasılıkla tehdit altına girecektir. Bu nedenle tehdit altında olan ya da olmayan tüm türler için yaşayabilir popülasyonların sürdürülmesini sağlamak amacı ile ortaya koyulan eylemler, türlerin yerinde korunmasını esas almalı ve bu eylem planları gerekli müdahale derecesine bağlı olarak tür yönetimi, eylem, koruma veya kurtarma planları olarak sınıflandırılmalıdır. Bu çalışmada, gelecekte gerçekleştirilmesi önerilen tür yönetimi planlarındaki ilk adım olması amacı ile Dünya Doğa ve Doğal Kaynakları Koruma Birliği (IUCN) Kırmızı Listesi’nde yer alan ve ülkemizde soyu tükenme tehlikesi altında bulunan Fabaceae familyasına ait türlerin (Lathyrus, Astragalus, Vicia, Lotus, Thermopsis) detaylı bir araştırması gerçekleştirilmiştir. Çalışmada, (1) Fabaceae familyasına ait türlerin yayılış gösterdiği biyocoğrafik bölgelere, (2) yetiştiği habitatlara, (3) ekolojik özelliklerine, (5) karşı karşıya oldukları tehditlere, (6) ekonomik önemlerine, (7) etnobotanik özelliklerine ve halk arasındaki kullanım olanaklarına ilişkin detaylara yer verilmiştir. Ayrıca bu çalışma ile, türlerin lokasyonlarına ait güncel kayıtlar da değerlendirilmiştir. Yapılan değerlendirmeler sonucunda familyaya ait türlerin doğal yaşam alanlarına yönelik en önemli tehdit unsurlarının iklim değişikliği, aşırı otlatma, arazi ıslahı, saman yapma ve erozyon, baraj yapımı ve kentleşmenin neden olduğu bozulmalar olduğu görülmüştür. Tarımsal faaliyetler ve insan kaynaklı habitat kaybı ve bozulmaları da önemli tehdit unsurlarındandır. Bu çalışmaya göre ülkemizin önemli genetik zenginliklerinden olan ve IUCN Kırmızı Liste’sindeki Fabaceae familyasına ait türlerin nesillerini devam ettirebilmeleri amacı ile gerekli koruma önlemlerinin alınması ve koruma bilincinin geliştirilmesi gerekmektedir. Ayrıca, bu türlerin kullanım alanlarının belirlenmesi, ekolojik ve ekonomik önemlerinin saptanması son derece önemlidir. Türlerin korunmasına yönelik eylem planlarının hazırlanması ve genetik çeşitliliğin de içinde yer aldığı sürdürülebilir koruma ve kullanım stratejilerinin geliştirilmesi ise bu türlerin tüm yönleriyle araştırılmasına bağlıdır.
Service to Human Beings is Service to God: A General Concern for Humanity
Authors: Quacoe-Takrama Philip
Published: March 2021

No leader can lead without serving; a leader must be humble and ready to bring to bear that attitude through service to others. It is also necessary for a leader to make his or her service to people a private affair. Hence service is not to be rendered for rewards because service must go unrewarded by people if it is to meet the Master’s standard. What is needed of humanity today, is the need to serve one another rather than looking for assistance from others. This is a theological reflection, leaning towards service to God which invariably comes through service to human beings. Humanity is today bedeviled with eye service leaders, who serve with the intent to make profit and with the mindset of gaining popularity. Many quickly seize ministry opportunities when the ministry is prominent, proving, popular, prestigious, fulfilling, and profitable but shy away if the opposite is the case. This paper posits that service in any capacity to people is regarded as service unto the Lord. Its stance is that the act of service is the sure way to go if the service of people is to make a meaningful and lasting impact on humanity.

Forward Modeling Populations of Flares from Tidal Disruptions of Stars by Supermassive Black Holes

Detections of the tidal disruption flares (TDFs) of stars by supermassive black holes (SMBHs) are rapidly accumulating as optical surveys improve. These detections may provide constraints on SMBH demographics, stellar dynamics, and stellar evolution in galaxies. To maximize this scientific impact, we require a better understanding of how astrophysical parameters interact with survey selection effects in setting the properties of detected flares. We develop a framework for modeling the distributions of optical TDF detections in surveys across attributes of the host galaxies and the flares themselves. This model folds in effects of the stellar disruption rate in each galaxy, the flare luminosity and temperature distributions, the effects of obscuration and reddening by dust in the host galaxy, and survey selection criteria. We directly apply this model to the sample of TDFs detected by the Zwicky Transient Facility, and find that the overall flare detection rate is in line with simple theoretical expectation. The model can also reproduce the distribution of total stellar mass and redshift of the host galaxies, but fails to match all details of the detected flares, such as their luminosity and temperature distributions. We also find that dust obscuration likely plays an important role in suppressing the TDF detection rate in star-forming galaxies. While we do not find that the unusual preference of TDFs to have hosts in post-starburst galaxies in the “green valley” can be entirely explained by selection effects, our model can help to quantify the true rate enhancement in those galaxies.

We present a direct comparison of the Pan-Andromeda Archaeological Survey (PAndAS) observations of the stellar halo of M31 with the stellar halos of six galaxies from the Auriga simulations. We process the simulated halos through the Auriga2PAndAS pipeline and create PAndAS-like mocks that fold in all observational limitations of the survey data (foreground contamination from the Milky Way stars, incompleteness of the stellar catalogs, photometric uncertainties, etc.). This allows us to study the survey data and the mocks in the same way and generate directly comparable density maps and radial density profiles. We show that the simulations are overall compatible with the observations. Nevertheless, some systematic differences exist, such as a preponderance for metal-rich stars in the mocks. While these differences could suggest that M31 had a different accretion history or has a different mass compared with the simulated systems, it is more likely a consequence of an underquenching of the star formation history of galaxies, related to the resolution of the Auriga simulations. The direct comparison enabled by our approach offers avenues to improve our understanding of galaxy formation as they can help pinpoint the observable differences between observations and simulations. Ideally, this approach will be further developed through an application to other stellar halo simulations. To facilitate this step, we release the pipeline to generate the mocks, along with the six mocks presented and used in this contribution.

We construct empirical models of star-forming galaxy evolution assuming that individual galaxies evolve along well-known scaling relations between stellar mass, gas mass, and star formation rate following a simple description of chemical evolution. We test these models by a comparison with observations and detailed Magneticum high-resolution hydrodynamic cosmological simulations. Galaxy star formation rates, stellar masses, gas masses, ages, interstellar medium, and stellar metallicities are compared. It is found that these simple look-back models capture many of the crucial aspects of galaxy evolution reasonably well. Their key assumption of a redshift-dependent power-law relationship between galaxy interstellar medium gas mass and stellar mass is in agreement with the outcome of the complex Magneticum simulations. Star formation rates decline toward lower redshift not because galaxies are running out of gas, but because the fraction of the cold interstellar medium gas, which is capable of producing stars, becomes significantly smaller. Gas accretion rates in both model approaches are of the same order of magnitude. Metallicity in the Magneticum simulations increases with the ratio of stellar mass to gas mass as predicted by the look-back models. The mass–metallicity relationships agree, and the star formation rate dependence of these relationships is also reproduced. We conclude that these simple models provide a powerful tool for constraining and interpreting more complex models based on cosmological simulations and for population synthesis studies analyzing the integrated spectra of stellar populations.
Improving z ∼ 7–11 Galaxy Property Estimates with JWST/NIRCam Medium-band Photometry

The past decade has seen impressive progress in the detection of z > 7 galaxies with the Hubble Space Telescope; however, little is known about their properties. The James Webb Space Telescope will revolutionize the high-z field by providing near-IR (i.e., rest-frame optical) data of unprecedented depth and spatial resolution. Measuring galaxy quantities such as resolved stellar ages or gas metallicity gradients traditionally requires spectroscopy, as broadband imaging filters are generally too coarse to fully isolate diagnostics such as the 4000 Å (rest-frame) break, continuum emission from aged stars, and key emission lines (e.g., [O ii], [O iii], Hβ). However, in this paper, we show that adding NIRCam images through a strategically chosen medium-band filter to common wide-band filter sets adopted by ERS and GTO programs delivers tighter constraints on these galactic properties. To constrain the choice of filter, we perform a systematic investigation of which combinations of wide-band filters from ERS and GTO programs and single medium-band filters offer the tightest constraints on several galaxy properties at redshifts z ∼ 7–11. We employ the JAGUAR extragalactic catalogs to construct statistical samples of physically motivated mock photometry and conduct SED-fitting procedures to evaluate the accuracy of galaxy property (and photo-z) recovery with a simple star formation history model. We find that adding >4.1 μm medium filters at comparable depth to the broadband filters can significantly improve photo-zs and yield close to order-of-magnitude improvements in the determination of quantities such as stellar ages, metallicities, SF-related quantities, and emission-line fluxes at z ∼ 8. For resolved sources, the proposed approach enables the spatially resolved determination of these quantities that would be prohibitive with slit spectroscopy.
