Published: July 2023

Nearly the entire (98%) and over a third of the East Asian population
of Brent Geese stage in Notsuke Bay and nearby sites of eastern
Hokkaido, Japan, during autumn and spring migration, respectively,.
Despite the region’s importance as a refueling site for migrating Brent
Geese, little is known about how these migrants use specific sites
within this region. In this study, we investigated the seasonal
variation in the movements and use of four key sites in the eastern
Hokkaido using radio telemetry. Notsuke Bay was the primary staging area
for Brent Goose in both seasons, but there were frequent movements
between Furen Lake in fall and between Kunashiri Island in spring. The
three sites lie in close proximity to one another in the Nemuro Strait,
enabling relatively quick (<30 minutes) flights between sites.
Consequently, these sites may be considered as one continuous habitat
during migration. Brent Geese primarily foraged on eelgrass beds at
night in fall and during the day in the spring. The occupancy rates of
marked geese within the protected areas of Notsuke Bay and Furen Lake
were 74% and 71% during autumn, and 64% and 87% during spring,
respectively. However, extending the buffer to 3 km from the boundaries
of the protected areas resulted in residency rates exceeding 90% during
both seasons. To effectively conserve these important staging sites in
the Nemuro Strait, we recommend expanding the protected areas and
including connecting waters between Notsuke Bay and Kunashiri Island and
Furen Lake.
Getting Membrane with Membrane Approach: 3D Polypyrrole Nanotube Array Membranes and Their Applications
Authors: Chen Panpan , Hang Tian
Published: July 2023

Conductive polymers, owing to their excellent properties such as good
conductivity and chemical stability, have been extensively studied for
various applications, especially in the fields of energy and
environmental science. Three-dimensional (3D) conductive polymer
structures, containing interconnected and continuous networks with high
specific surface areas, are encouraging platforms with superior
performance. Despite the rapid advances in nanofabrication technology,
achieving conductive polymer superstructures with ordered features
remains challenging, such as in aligned nanochannels. Herein, we report
a facile and efficient template synthesis method to fabricate 3D
polypyrrole membrane structures. Using flexible, track-etched
polycarbonate membranes as the template, polypyrrole nanotube arrays can
be synthesized by chemical polymerization with tunable length and
diameter. Free-standing, 3D nanotube array membranes with vertically
aligned channels and continuous connecting layers were obtained simply
by template removal. This “getting membrane with membrane” approach is
also scalable and low-cost. We further demonstrated that the delicate
membrane structures can be used in various applications, including
adsorbents, solar steaming materials, gas sensors, and supercapacitors.
It exhibited quick and excellent adsorption performance for Cr(VI) ions;
can be directly served as a solar interfacial evaporator without surface
modification and substrate support; showed extraordinary sensing
response toward NH3, displayed great potential for energy storage
materials with satisfactory electrochemical performance. Our work
provides a feasible way to fabricate polypyrrole superstructures and
expands the applications of 3D conductive polymer materials.
Refining the Transmission Map and Air Light in the Atmospheric Light Scattering Model for An Efficient Single Image Dehazing Method
Authors: ÇİMTAY Yucel
Published: July 2023

Many dehazing methods have been presented by many researchers either on
single hazy images or multiple images like videos. With the increasing
volume of hazy image datasets, recent literature about dehazing is
mostly based on deep learning methods. Although, deep learning models
perform better than traditional methods on the validation data of the
specific dataset which they are trained with, the generalization
performance of deep learning models is generally poor. Another important
bottleneck for deep models is the training cost in terms of time and
hardware requirements. In this study, traditional DCP method is improved
by taking into account the amount of haze and refining the transmission
and air light used in atmospheric light scattering model of haze.
Results of this study shows that proposed method is superior and/or
competitive to traditional DCP method and state of the art deep learning
models in terms of the visual quality of the dehazed image.
Entropy generation in MHD Pulsatile Casson Two-immiscible fluid flow in a vertical non-Darcy porous media with slip effects
Authors: Devi M. Padma , Srinivas S. , Vajravelu K.
Published: July 2023

The unsteady two immiscible MHD free convective flow of Casson liquid
through a vertical channel, with a porous medium, is studied numerically
in this investigation. Using a double perturbation approach, the
governing flow equations are reduced to a system of connected partial
differ ential equations, which are then solved using the 4th-order
numerical  Runge-Kutta method coupled with the shooting approach in
Mathematica. The velocity and thermal slip conditions have been
accommodated in this model. The interaction of permeability of the
porous medium, energy dissipation, Joule heating, and thermal radiation
are taken into consideration. The computational upshot is also de-
scribed explicitly to examine the consequences of pertinent parameters.
The computational results are analyzed to investigate the effects
associated with pertinent parameters which include the Hartmann number
of two regions, Darcy number, a ratio of Porous medium permeability,
Grashof number, Radiation parameter, heat source, and Prandtl num ber.
The characteristics of the essential regulating parameters on flow
frameworks of velocity, temperature, Entropy generation, Bejan number,
and heat transfer rate are analyzed correctly via plots, and skin
friction and flow rate are given in tabular form. As the radiation
parameter raises both the velocity and temperature of the Casson fluid
decreases.  The rate of entropy generation falls with a rise in the
magnetic field. The Bejan number escalates as it moves forward from the
lower wall to the channel’s center. In the later part of the channel,
the Bejan number starts to drasti- cally fall and reaches a minimum at
the upper wall.
Research on evolution process of full-layer incision of skin tissue under different laser incidences
Authors: Wang Kehong , Chen Yuxin , Huang Jun , Rui Yunfeng , Fan Wentao
Published: July 2023

Considering difficulties of achieving vertical incidence of beam in
different positions of skin, it’s significant to study potential effects
of incidence angles of laser on incisions. Surgical platform with a
1064nm continuous fiber laser was established. Incident angle was
adopted and real-time temperature fluctuations in laser operating area
could be monitored. The rats were treated with laser at day 0 and day 3
after incision modeling, and H&E, Masson, Sirius Red and
Immuno-histochemical staining and enzyme-linked immunosorbent assay were
adopted at day 3,7,14 to analyze the performance of healing. Laser with
energy density of 67.54J/mm can effectively
accelerate wound healing in vivo, in which laser with incident angle
around 60° can effectively avoid scar hyperplasia. Therefore, the use of
low energy laser with small deflection angle has a good clinical
application prospect in promoting wound healing.

Published: July 2023

Background: As a leading cause of chronic kidney disease, clinical demand for noninvasive biomarkers of diabetic kidney disease (DKD) beyond proteinuria is increasing. Metabolomics is a popular method to identify mechanisms and biomarkers. We investigated urinary targeted metabolomics in DKD patients. Methods: We conducted a targeted metabolomics study of 26 urinary metabolites in consecutive patients with DKD stage 1 to 5 (n = 208) and healthy controls (n = 26). The relationships between estimated glomerular filtration rate (eGFR) or urine protein-creatinine ratio (UPCR) and metabolites were evaluated. Multivariate Cox analysis was used to estimate relationships between urinary metabolites and the target outcome, end-stage renal disease (ESRD). C statistics and time-dependent receiver operating characteristics (ROC) were used to assess diagnostic validity. Results: During a median 4.5 years of follow-up, 103 patients (44.0%) progressed to ESRD and 65 (27.8%) died. The median fold changes of nine metabolites belonged to monosaccharide and tricarboxylic acid (TCA) cycle metabolites tended to increase with DKD stage. Myo-inositol, choline, and citrates were correlated with eGFR and choline, while mannose and myo-inositol were correlated with UPCR. Elevated urinary monosaccharide and TCA cycle metabolites showed associations with increased morality and ESRD progression. The predictive power of ESRD progression was high, in the order of choline, myo-inositol, and citrate. Although urinary metabolites alone were less predictive than serum creatinine or UPCR, myo-inositol had additive effect with serum creatinine and UPCR. In time-dependent ROC, myo-inositol was more predictive than UPCR of 1-year ESRD progression prediction. Conclusion: Myo-inositol can be used as an additive biomarker of ESRD progression in DKD.
Los universitarios y sus percepciones con respecto al liderazgo ejercido por parte del personal directivo
Authors: Melo Rojas Gina Marcela , Hernández Herrera Claudia Alejandra
Published: July 2023

El objetivo del presente trabajo fue analizar las percepciones de estudiantes en relación con los tipos de liderazgo transformacional, transaccional y laissez-faire para determinar el que prevalece en una unidad académica de enseñanza superior del Instituto Politécnico Nacional de México. Para ello, se llevó a cabo un estudio cuantitativo en el que empleó un muestreo no probabilístico, donde participaron 796 estudiantes de seis programas académicos. Los datos se obtuvieron por medio del cuestionario CELID y fueron analizados mediante el software SPSS; además, se aplicó análisis factorial exploratorio y la prueba de Kruskal-Wallis. Se encontró que el liderazgo con mayor prevalencia en la unidad académica fue el laissez-faire, seguido del transaccional y del transformacional. Aunado a lo anterior, en relación con el liderazgo transformacional, los jóvenes dieron calificaciones bajas al orgullo, el respeto y la confianza hacia el trabajo del personal directivo. Asimismo, se evidenció una insuficiente capacitación, carencia en la motivación y, por ende, muy baja cultura relacionada con el éxito. En cuanto al liderazgo transaccional, se evidenció que las autoridades evitan realizar cambios en lo establecido, mientras que en lo relacionado con el liderazgo laissez-faire se encontraron carencias en la comunicación y en las formas de localizar a los directivos. Se concluye, por tanto, que es necesario implementar acciones para incrementar la credibilidad y confianza en los líderes de dicha unidad académica, aunado al desarrollo de programas intensivos de formación y capacitación de líderes para los futuros cuadros directivos.

Authors:   West Ukrainian National University, Dyvak Mykola , Manzhula Volodymyr ,   West Ukrainian National University, Dyvak Taras ,   West Ukrainian National University
Published: July 2023

The article proposes an approach to parametric identification of interval nonlinear models of static systems based on the standard problem of minimizing the root mean square deviation between the values ​​of the modeled characteristics of the static object and the values ​​belonging to the experimental intervals. As a result of expanding the parameter space of nonlinear models by introducing additional coefficients to match the predicted and experimental values into the objective function, a multidimensional optimization problem with a nonlinear multiextremal objective function is obtained. The paper examines the characteristics of the objective function and the convergence of its optimization.

Attitudes and Knowledge in High School Science: An Empirical Test of a Theoretical Model of Correlations
Authors: Quirós Oscar E. , Chaverri Gloriana , Iturralde-Polit Paula , Sandi-Ureña Santiago
Published: July 2023

It has been discussed that emotional investment in the educational process generates positive cognitive outcomes. This correlation addresses a core tenet of the three learning domains, Cognitive, Affective, and Psycho-Motor where all three constitute separate areas of one single learning process. And as such, one would expect to be able to measure this correspondence between the three domains. This study attempts to test the hypothesis of a correlation between the cognitive and affective domains in a cohort of in-service science teachers. Specifically, we seek to assess whether the affective posture towards school sciences shows an association with their cognitive competence in biology, chemistry and physics. We used partial least square regression analysis to examine the data, and the results indicate a direct correlation between the affective and cognitive domains. Teachers who scored higher in cognitive tests for the three sciences also had a more positive attitude towards them. These findings provide strong empirical evidence in support of the theoretical principle that the three domains are separate but interconnected components of the educational process.

Published: July 2023

In providing a therapy treatment to a patient with depression, the communication between a psychiatric doctor and a patient with depression must not be limited solely during the therapy session. Therefore, this study aims to identify the appropriate mobile application according to the types of depression therapy that require mobile application-based therapy for adolescents with depression. The participants in this study were recruited based on purposive sampling. The first round which consisted of four psychiatric doctors involved two males and two females participating in this study followed by participation of 14 experts in the second round. This study which employed the Fuzzy Delphi Method revealed that Whatsapp is necessary and thus categorized as the main based–therapy for adolescents with depression and Cognitive Behavioural Therapy has been acknowledged as the most suitable type of depression therapy that needs mobile application-based therapy for adolescents with depression. This method is useful to design a particular based-therapy module for the doctors to use in mobile application for adolescents with depression. The results of this study would be useful for doctors, particularly in using Whatsapp as a based therapy to interact with adolescents with depression in the future.
Exploring Iraqi EFL Learners' Command of basic Grammatical Structures at the Tertiary level
Authors:   Department of English, College of Arts, University of Mosul,  Iraq., Algburi Basim Yahya Jasim
Published: July 2023

Language learning has been equated with learning it's grammar. The view was that mere words without grammar of some kind do not constitute a language. This view has been challenged by the communication-based approaches which relegated grammar to a secondary status. The new English course for Iraq which was the prescribed course for teaching English as a foreign language from 1972 to 2004 which was structurally- based has been deserted and since then there has been a shift to communication based courses in which grammar is assumed to be a by-product which develops automatically while emphasis is placed on communication. The present study aims at testing this assumption to see whether students have mastered the basic grammatical notions and structures after 12 years of studying English using communication-based syllabuses. The research questions addressed were: to what extent have Iraqi students mastered the grammatical notions and structures? Which notions and structures had not been adequately mastered? The results indicate that the basic grammatical structures and notions have not been adequately mastered after a long period of studying English at the tertiary level and the students still find difficulty in most grammatical structures, including comparative constructions, concord, passivization, and perfective aspects. The reasons were identified and suggestions for overcoming the difficulties in these areas were made.

Published: July 2023

The present study investigates the effect of the modality principle in multimedia learning during the teaching of drama at the English department at a Saudi university, the University of Ha’il. It compares explicitly the impact of using static pictures and narration concurrently with on-screen text for the control group with the impact of using pictures with narration only for the experimental group. A sample of 69 male English-majoring students was selected and divided into control and experimental groups. The aim was to determine which group performed better than the other with the hypothesis that audio-visual presentation of the selected content would enhance students’ knowledge retention and mental skills and would lead to better learning outcomes for the experimental group. A quasi-experimental design was adopted and ANCOVA test was used to observe variation in the scores of the two groups after studying Hamlet’s play. The results support the hypothesis. Students in the experimental group outperformed their counterparts in the control group. This was observed in the post-tests on the retention of knowledge and mental skills. The findings of this study provide additional evidence of the superiority of audio-visual presentation in a previously unstudied context related to the teaching of literary content.
