Sustainable Development Model of Performance of Woodworking Enterprises in the Czech Republic

The current requirements put on the Member States of the European Union (“EU”) in the area of sustainability and climate-neutral economy through strategic visions such as “Agenda 2030” or “A Clean planet for all” demonstrate the increasing need for quick identification of the changes required in the use of renewable and nonrenewable natural resources. Forests are a particular specific area of such changes. They represent a part of the ecosystem that is important for society from the economic, social, and environmental perspectives. Current climate changes have had a negative effect on the state of forestry in the Czech Republic and have raised many questions of how to ensure its sustainability. Besides the changes in forestry, the situation has also affected the sector primarily depending on the production function of forests and whose coexistence is conditioned. Taking specific sectors as examples, the article presents some prospects that could result in more efficient use of resources and defines potential synergic effects. Analyses of primary and secondary information sources were used to create preferential models (the term “preferential” in the context of the article represents opportunities through which it is possible to achieve an improvement in competitiveness and market advantage over the current model of wood processing and timber trade in the Czech Republic. The model works with potential perspectives and respects the challenges in the field of sustainable development) of timber and wood raw material production and processing and preferential and of economic efficiency (the term “efficiency” in the article represents the technical efficiency of the use of resources to achieve maximum economic benefit and added value. The aim is to increase the economic potential of individual sectors of primary and secondary processing in relation to timber sources) of woodworking businesses. The production model indicates that the energy use of wood, the expansion of the production mix in construction, the use of biomass and digestate in agroforestry, and the logging waste recovery are the most prospective sectors. The model presenting preferential areas in the woodworking industry development with respect to sustainability identified the need to increase associated production and material efficiency in construction and energy sectors, as well as insufficient activity of the sectors associated with technological innovations, FSC and PEFC certification prospects, bioeconomy and circular economy, a considerable need for wage growth in the sector and increased use of the existing production capacities by both domestic and foreign sales.
Digital Proficiency and Psychological Well-Being in Online Learning: Experiences of First-Generation College Students and Their Peers

The study examines the role of digital proficiency in relation to psychological well-being of a vulnerable population—first-generation college students (FGS)—and their counterparts, continuing-education students, in online learning during the coronavirus pandemic (COVID-19). Informed by positive computing and FGS studies, this paper empirically tests a model of three key influencing factors by using a data sample (n = 309) collected from a minority-serving university in the U.S. in April 2020. Our data analysis confirms that FGS underperformed in digital proficiency, compared to their peers. Moreover, digital proficiency had a significant effect on individual psychological well-being, regardless of a student’s generational status. Our paper contributes to the positive computing research by empirically demonstrating the association between users’ technology competence and psychological well-being. Practically, our findings highlight the importance of implementing educational programs and policies to promote the digital skills and well-being of underserved students such as FGS in college education.
High fidelity modeling of thermal relaxation and dissociation of oxygen

A master equation study of vibrational relaxation and dissociation of oxygen is conducted using state-specific O2–O transition rates, generated by extensive trajectory simulations. Both O2–O and O2–O2 collisions are concurrently simulated in the evolving nonequilibrium gas system under constant heat bath conditions. The forced harmonic oscillator model is incorporated to simulate the state-to-state relaxation of oxygen in O2–O2 collisions. The system of master equations is solved to simulate heating and cooling flows. The present study demonstrates the importance of atom-diatom collisions due to the extremely efficient energy randomization in the intermediate O3 complex. It is shown that the presence of atomic oxygen has a significant impact on vibrational relaxation time at temperatures observed in hypersonic flow. The population of highly-excited O2 vibrational states is affected by the amount of atomic oxygen when modeling the relaxation under constant heat bath conditions. A model of coupled state-to-.
Unveiling the International Students’ Perspective of Service Quality in Chinese Higher Education Institutions

Foreign students’ satisfaction with the service quality of Chinese universities is essential for the sustainable internationalization of China’s higher education system. The present study employs a survey research method to bring in the foreign students’ perspective of the various aspects of service quality in seven key Chinese universities. Accordingly, 618 valid questionnaires were analyzed using descriptive statistics, principal component analysis (PCA), and analysis of variance (ANOVA). The study findings posit that, although foreign students affirm that teachers are supportive and well qualified, they have concerns about the English proficiency of instructors. Likewise, foreign students were not satisfied with the frequency of formal research meetings with their advisers and the assistance with research techniques and relevant literature sources. Overall, female foreign students were less satisfied than their male counterparts. Moreover, foreign students reported higher satisfaction from teaching services and learning resources, moderate satisfaction from advisory services, and meager satisfaction from the administrative and support services of their respective Chinese institutions. Besides, we found significant differences between sample Chinese universities on various constructs of service quality. Likewise, arts and social sciences students were less satisfied with the service quality of the institution as compared to their natural sciences and engineering counterparts. The policy implications of this research for various stakeholders are discussed.
Letter. Partition of Al between Phase D and Phase H at high pressure: Results from a simultaneous structure refinement of the two phases coexisting in a unique grain

Abstract The crystal structure of the two dense hydrous magnesium silicates Phase D, MgSi2H2O6, and Phase H, MgSiH2O4, synthesized at 45 GPa and 1000 °C and coexisting in the same micrometer-sized grain, was investigated by single-crystal X‑ray diffraction to study the preferential partition of Al between the two structures. In agreement with the literature, Phase D was found to be trigonal, space group P3̅1m, with lattice parameters a = 4.752(2), c = 4.314(2) Å, V = 84.37(6) Å3 (R1 = 0.020), and Phase H was found to be orthorhombic, space group Pnnm, with lattice parameters a = 4.730(2), b = 4.324(2), c = 2.843(2) Å, V = 58.15(5) Å3 (R1 = 0.024). The estimated proportion (vol%) of the two phases from the refinement is 27(2)PhD - 73PhH. The analysis of the geometric details of the two structures shows that Phase D hosts almost all the Al available, whereas Phase H is nearly identical to pure MgSiH2O4. Overexposed electron-microprobe X‑ray maps of the same grain used for the X‑ray diffraction study together with WDS spots on the two phases confirmed the structural results. Thus, our results suggest that when Phase D and Phase H coexist, Al is strongly partitioned into Phase D at the expense of coexisting Phase H. At pressure above ~50 GPa, where Phase D is no longer stable, Phase H is able to incorporate the high aluminum contents present in hydrous peridotitic compositions in the deep lower mantle and be stabilized at the expense of Phase D and magnesium silicate perovskite.
The Online Collaborative Learning Design Webinar: A Case Study of Thai Open University's Graduate Students in a Science Education Programe

In the COVID-19 pandemic situation, online education is an interesting way to enable learning anywhere. Especially in postgraduate instruction, the student's arguments, and shared knowledge and experiences with colleges are important and can be enhanced by collaborative learning activities in certain seminar courses. The purpose of this study is to evaluate the effectiveness of using the webinar on Microsoft teams considered from satisfaction towards the webinar and attitude toward MST. The participants were 40 graduate students who enrolled in a seminar in science curriculum and instruction course at Sukhothai Thammathirat Open University. The research tools were as follows: 1) A satisfaction towards the webinar questionnaire, 2) attitude toward the MST questionnaire, and 3) an interview form. The mean, standard deviation and content analysis were used for data analysis. The results of this study indicated that the vast majority of graduate students had felt satisfaction towards the webinar and attitude toward MST were scored at an overall high level. The results suggested that the collaborative learning on webinars could be an appropriate alternative to be used as supplement for traditional face-to-face learning, particularly when there is a need for locational flexibility.
Vibration Analysis of Axially Functionally Graded Non-Prismatic Euler-Bernoulli Beams Using the Finite Difference Method

This paper presents an approach to the vibration analysis of axially functionally graded (AFG) non-prismatic Euler-Bernoulli beams using the finite difference method (FDM). The characteristics (cross-sectional area, moment of inertia, elastic moduli, and mass density) of AFG beams vary along the longitudinal axis. The FDM is an approximate method for solving problems described with differential or partial differential equations. It does not involve solving differential equations; equations are formulated with values at selected points of the structure. The model developed in this paper consists of formulating differential or partial differential equations with finite differences and introducing new points (additional or imaginary points) at boundaries and positions of discontinuity (concentrated loads or moments, supports, hinges, springs, and brutal change of stiffness). The introduction of additional points allows satisfying boundary and continuity conditions. Vibration analysis of AFG non-prismatic Euler-Bernoulli beams was conducted with this model, and natural frequencies were determined. Finally, the direct time integration method (DTIM) was presented. The FDM-based DTIM enabled the analysis of forced vibration of AFG non-prismatic Euler-Bernoulli beams, considering the damping. The efforts and displacements could be determined at any time.
Atmosphere‐Ionosphere (A‐I) Coupling as Viewed by ICON: Day‐to‐Day Variability Due to Planetary Wave (PW)‐Tide Interactions

Coincident Ionospheric Connections Explorer (ICON) measurements of neutral winds, plasma drifts and total ion densities (:=Ne, electron density) are analyzed during January 1–21, 2020 to reveal the relationship between neutral winds and ionospheric variability on a day‐to‐day basis. Atmosphere‐ionosphere (A‐I) connectivity inevitably involves a spectrum of planetary waves (PWs), tides and secondary waves due to wave‐wave nonlinear interactions. To provide a definitive attribution of dynamical origins, the current study focuses on a time interval when the longitudinal wave‐4 component of the E‐region winds is dominated by the eastward‐propagating diurnal tide with zonal wavenumber s = −3 (DE3). DE3 is identified in winds and ionospheric parameters through its characteristic dependence on local solar time and longitude as ICON's orbit precesses. Superimposed on this trend are large variations in low‐latitude DE3 wave‐4 zonal winds (±40 ms−1) and topside F‐region equatorial vertical drifts at periods consistent with 2‐days and 6‐days PWs, and a ∼3‐day ultra‐fast Kelvin wave (UFKW), coexisting during this time interval; the DE3 winds, dynamo electric fields, and drifts are modulated by these waves. Wave‐4 variability in Ne is of order 25%–35%, but the origins are more complex, likely additionally reflecting transport by ∼20–25 ms−1 wave‐4 in‐situ winds containing strong signatures of DE3 interactions with ambient diurnal Sun‐synchronous winds and ion drag. These results are the first to show a direct link between day‐to‐day wave‐4 variability in contemporaneously measured E‐region neutral winds and F‐region ionospheric drifts and electron densities.
Collaborative learning and student engagement in practical skills acquisition

ABSTRACT This study examines how collaborative learning (CL) activities might help to improve student engagement in practical skills acquisition (SEPSA). Using a time lagged data from 205 undergraduate students of Nigerian public universities, the direct effect of CL on SEPSA and the mediating effects of task value, mastery goal orientation and performance goal orientation were tested using Hayes-PROCESS Macro 3.5. The regression results indicate that CL associated positively with SEPSA as well as task value and mastery goal orientation, and not for performance goal orientation. However, the mediation analysis suggests that task value and mastery goal orientation mediate CL activities and SEPSA. Our findings highlight the important potentials of CL for increasing SEPSA. The present study has implications for higher education teachers and administrators, educators, policymakers, students and researchers who are in search of effective strategies for improving student engagement in practical skills acquisition and learning.
Multiomic analysis to reveal distinct molecular profiles of uterine and nonuterine leiomyosarcoma.

11555 Background: Leiomyosarcoma (LMS) is a rare group of mesenchymal malignancies found in the uterus, retroperitoneum, skin, or other soft-tissue sites. Treatment for LMS is extrapolated from trials including both uterine (uLMS) and non-uLMS subtypes, although whether they respond similarly and have similar outcomes from treatment is not clear. We examined the molecular composition of LMS by site of origin to better inform future drug development and trial design. Methods: We reviewed 1115 specimens with LMS histology tested by Caris Life Sciences for targeted exome (NextSeq, 592 gene panel), whole exome, and whole transcriptome sequencing (NovaSeq). Specimens were stratified into uLMS, rpLMS (retroperitoneal), and otherLMS (non-uterine/retroperitoneal) subgroups based on tumor origin sites. Genomic data was analyzed for mutations, copy number aberrations, and fusions. RNA expression profiling included evaluation of individual genes and gene set enrichment analysis (GSEA). P-value adjustment performed by the Benjamini-Hochberg procedure. Results: The study cohort was comprised of 62.9% uLMS (n = 701), 14.9% rpLMS (n = 166) and 22.2% otherLMS (n = 248) specimens. Overall, LMS specimens most frequently harbored TP53 (64%, n = 612), ATRX (30%, n = 219), RB1 (22%, n = 156), and MED12 (16%, n = 94) mutations, with these genes accounting for 74.4% (n = 1044) of all observed pathogenic/likely pathogenic mutations. RB1 mutations were significantly less common in uLMS (15%) compared to rpLMS (30%, p < 0.05) and otherLMS (33%, p < 0.01), whereas MED12 mutations were almost exclusive to uLMS (22% vs 1% rpLMS, 3% otherLMS, p < 0.05). MAP2K4 copy number amplification were more common in rpLMS (22%, p < 0.001) and otherLMS (14%, p < 0.182) compared to uLMS (7%), with frequent co-amplification of nearby genes ( FLCN, GID4, SPECC1, GAS7, PER1, and AURKB) located at chr17p11-13. Actionable gene fusions involving ALK (2.1%, n = 11), FGFR1 (0.2%, n = 1), and NTRK1/2 (0.2%, n = 1 each) were rare overall, with similar prevalence across subtypes. Genomic alteration rates were not significantly different between rpLMS and otherLMS subtypes . RNA expression profiling identified significant upregulation of PI3K/AKT/mTOR, DDR, WNT/Beta-Catenin pathway genes in non-uLMS. GSEA indicated several immune-related gene sets were enriched in rpLMS and otherLMS compared to uLMS. Conclusions: Comprehensive molecular profiling suggests that LMS originating from the uterus represents a molecularly distinct disease compared to other primary sites of origin. We identified key genomic patterns which have potential for targeted therapy. These data provide insight for the framework of future clinical trials designed to separate uLMS from non-uLMS histologies, although further subdivision does not appear to be warranted.
Adjuvant chemotherapy following chemoradiation as primary treatment for locally advanced cervical cancer compared to chemoradiation alone: The randomized phase III OUTBACK Trial (ANZGOG 0902, RTOG 1174, NRG 0274).

LBA3 Background: Cervical cancer is a common cause of cancer-related death among women worldwide. Standard treatment for locally advanced disease is chemoradiation. However, a significant percentage of women still relapse and die from the development of distant metastatic disease. OUTBACK was designed to determine the effects of giving adjuvant chemotherapy after chemoradiation on survival. Methods: OUTBACK is an international randomized phase III trial of the Gynecologic Cancer InterGroup (GCIG). Participating groups (countries) included ANZGOG (Australia and New Zealand), NRG (USA, Saudi Arabia, Canada, China), and Singapore. Eligible women had locally advanced cervical cancer (FIGO 2008 stage IB1 and node positive, IB2, II, IIIB or IVA) that was suitable for primary treatment with chemo-radiation with curative intent. Women were randomly assigned to either standard cisplatin-based chemo-radiation (control) or standard cisplatin-based chemo-radiation followed by adjuvant chemotherapy (ACT) with 4 cycles of carboplatin and paclitaxel, after stratification for nodal status, participating site, FIGO stage, age, and planned extended-field radiotherapy. The primary end point was overall survival (OS) at 5 years. Secondary endpoints included progression-free survival (PFS); adverse events (AE); and patterns of disease recurrence. The target sample size of 900 provided 80% power with 95% confidence to detect an improvement in OS at 5 years from 72% (control) to 80% (ACT), with some over-accrual to account for non-compliance with ACT and loss to follow-up. Results: 919 of 926 women recruited from April 2011 to June 2017 were eligible and included in the primary analysis: 463 assigned ACT, 456 control. ACT was started in 361 (78%) women assigned to receive it. Median follow-up was 60 months (IQR 45-65). OS at 5 years was similar in those assigned ACT versus control (72% vs 71%, difference <1%, 95% CI -6 to +7; P = 0.91). The hazard ratio for OS was 0·91, (95% CI 0.70 to 1.18). PFS at 5 years was similar in those assigned ACT versus control (63% vs 61%, difference 2%, 95% CI -5 to +9; P = 0.61). The hazard ratio for PFS was 0·87, (95% CI 0.70 to 1.08). AE of grade 3-5 within a year of randomisation occurred in 81% who were assigned and received ACT versus 62% assigned control. There was no evidence of differences between treatment groups in AE beyond 1 year of randomisation. Patterns of disease recurrence were similar in the two treatment groups. Conclusions: Adjuvant chemotherapy given after standard cisplatin-based chemoradiation for women with locally advanced cervical cancer did not improve OS or PFS.

Biomarkers of dietary patterns: a systematic review of randomized controlled trials

Abstract Context Most methods for assessing dietary intake have considerable measurement error. Dietary biomarkers are objective tools for dietary assessment. Dietary biomarkers of dietary patterns have not been well described, despite modern dietary guidelines endorsing dietary patterns. Objective This systematic review sought to describe the dietary biomarkers commonly used to assess dietary patterns, and the novel biomarkers of dietary patterns identified by exploratory studies. Data Sources MEDLINE, Embase, Cochrane Central, PreMEDLINE, and CINAHL databases were searched. Data Extraction Data extraction and bias assessment were undertaken in duplicate. Data Analysis A qualitative approach was applied, without statistical analysis. Conclusion In controlled settings, dietary biomarkers of single nutrients or of individual foods or food groups are commonly used to assess compliance with dietary patterns. However, currently, there are no dietary biomarkers or biomarker profiles that are able to identify the specific dietary pattern that has been consumed by an individual. Future work should seek to validate novel dietary biomarkers and biomarker profiles that are indicative of specific dietary patterns and their characteristics. A dietary biomarker panel consisting of multiple biomarkers is almost certainly necessary to capture the complexity of dietary patterns. Systematic Review Registration PROSPERO registration no.

On the use of the field Sunset semi-continuous analyzer to measure equivalent black carbon concentrations

ABSTRACT This study describes a method to calculate equivalent black carbon (EBC) concentrations comparable to those obtained from optical filter-based EBC instrumentation from data obtained with a semi-continuous thermo-optical analyzer (Sunset Laboratory Inc., USA) without any need of instrument alterations or extra costs. A correction for the reflection of the Sunset analyzer laser beam by the walls of the sampling tube is introduced. EBCSunset concentrations obtained during two intensive campaigns in Prague (one in winter and one in summer) were compared also to EBC measured by an AE31 Aethalometer (EBCaeth), an AE51 MicroAethalometer (EBCmicro), and a Multi Angle Absorption Photometer (EBCMAAP). Good agreement was observed in both campaigns. The EBCSunset data were also corrected for loading effects in two ways—a simple loading correction and a total correction using data also from the MAAP and a nephelometer. The loading corrections gave similar results for EBCSunset and the aethalometer data except for the simple correction for summer EBCSunset data. The multiple scattering correction factors computed for EBCSunset agreed well with those calculated for EBCaeth. The wall reflection correction for the Sunset analyzer data further improves the agreement between EBCSunset and EBCMAAP. Copyright © 2016 American Association for Aerosol Research
