Research Trends in Science and Mathematics Education in South Korea 2014–2018: A Cross-Disciplinary Analysis of Publications in Selected Local Journals
Authors: Park Wonyong , Kim Doy , Kang Da Yeon 
Published: November 2021

Abstract
Although science education and mathematics education share many characteristics as neighboring research disciplines, comparisons between the two research fields in the literature have rarely been made. In this study, we examine the two fields’ similarities and differences in the local context of South Korea by analyzing 2,426 research articles published in 15 selected local journals from both fields. The analysis revealed interesting commonalities and divergences across the two fields, suggesting a high degree of similarity in the distribution of research topics across the two fields. Nevertheless, some topics were more frequently studied in one field than the other. Based on the results, we suggest that understanding the ongoing research agendas and aims of adjacent disciplines such as mathematics education will be beneficial to the science education community by allowing self-reflection and facilitating interdisciplinary communication and collaboration. Several potential ways in which the two disciplines can cross-fertilize are discussed.
Effect of ethical nurse leaders on subordinates during pandemics
Authors: Zhou Jinyi , Zhang Ke-fu 
Published: November 2021

Background: As caring in times of pandemics becomes extremely stressful, the volume and intensity of nursing work witness significant increase. Ethical practices are therefore even more important for nurses and nurse leaders during this special period. Research aim: The aim was to explore the relationship between ethical nurse leaders and nurses’ task mastery and ostracism, and to examine the mediating role of relational identification in this relationship during pandemics. Research design: Based on social exchange theory, this study tests a theoretical model proposing that ethical nurse leaders can increase nurses’ task mastery and reduce their ostracism by improving their relational identification with leaders during pandemics. Participants and research context: A multilevel and multi-wave field study using data from 172 nurses from 45 departments of two comprehensive hospitals was performed from April to August 2020 to test proposed hypotheses. Ethical considerations: We received formal approvals from the ethical committee of the hospital where we conducted this study before the data collection. Results: Ethical nurse leaders can indeed increase nurses’ task mastery and reduce their ostracism during the pandemic period; furthermore, nurses’ identification with their leaders mediates these relationships. We find that ethical leadership plays an even more important role in improving nurses’ task mastery and reducing their ostracism that may be facilitated by pandemics this special time. Nurses will become more identified with their leaders when they are treated by ethical ways. Discussion: The study tries to advance our understanding of the important role of ethical leadership in nurse management literature and provide useful suggestions for healthcare institutions, nurse leaders, and nurses during pandemics. Conclusion: Theoretical contributions and practical implications of our findings are discussed. Specifically, we suggest that healthcare institutions cultivate ethical nurse leaders to facilitate nurses’ relational identification, which in turn will positively influence work outcomes.
Monetary Policy Pass-through, Ownership and Crisis: How Robust is the Indian Evidence?
Authors: Ansari Jugnu , Ghosh Saibal 
Published: November 2021

Employing disaggregated data for 2001–2016, this study investigates the lending and loan pricing behaviour of state-owned and domestic private banks in response to monetary policy. Three major findings emerge. First, although both the interest rate and the bank lending channels are relevant for monetary pass-through, there is a trade-off: the impact of the former is much higher than the latter, although it occurs with a significant lag. Second, domestic private banks have a far greater response to a monetary policy shock under the interest rate channel, whereas state-owned banks display a greater response under the bank-lending channel. And finally, state-owned banks cut back lending during periods of crises, although no such response is manifest in domestic private banks. JEL Codes: C23, D4, E43, E52, G21, L10
Do Size-dependent Tax Incentives Discourage Plant Size Expansion? Evidence from Panel Data in Indian Manufacturing
Authors: Ramaswamy K. V. 
Published: November 2021

The article presents a new empirical application of the idea of threshold burden of tax incentives in India. The Indian government provided tax exemption to manufacturing units with sales turnover below a specified level over the years. The turnover threshold limit was US$1 million in 2009. Whether size-based tax rules incentivise firms to reorganise their production structure in order to stay below the threshold to take advantage of fiscal incentives is the key question addressed in this article. A significant factor that is widely believed to encourage small firms to stay small has been the tax incentives in the form of excise tax (turnover tax) exemptions below a specified value of sales each year. A key strategy followed by Indian firms to stay small and below the threshold has been product subcontracting or capacity subcontracting. We provide econometric evidence on this particular mechanism. The study is based on a unique unbalanced panel data of 29,213 manufacturing plants spanning the period 1999–2008 and a panel of 4,613 manufacturing firms covering the period 1990–2010. Average subcontracting intensity was found to be significantly higher in manufacturing establishments and firms with sales turnover below the ceiling level set by the tax rules. Econometric tests supported the hypothesis that establishments take advantage of tax incentives by staying below the threshold value of output. Econometric tests for a subgroup of domestic-market-oriented firms provide additional support to the hypothesis of threshold effects. These findings are relevant for policy design in developing and emerging economies. JEL Classification: O14, O17, L60, H32, H25
Cooking Fuels and Respiratory Infirmity in Rural Barak Valley: An Analysis of Pradhan Mantri Ujjwala Yojana Period
Authors: Das Monalisa , Sen Alok 
Published: November 2021

This study is an attempt to examine the fuel use pattern and its impact on the respiratory health of the users in the rural area of Barak Valley region of southern Assam. The effectiveness of Pradhan Mantri Ujjwala Yojana (PMUY) in mitigating the practice of unclean fuel has also been analysed in this study along with other related issues. The results based on personal information of 2,541 individuals from 530 households of Barak Valley reveal that incidence of respiratory illness is more profound in the households of solid biomass fuel users. The study further reveals that though PMUY has equipped the rural households with clean fuel connections but failed to change the fuel use practice of the beneficiaries. Among the barriers of clean fuel use practices, insufficient income of the households and availability of free and low-cost alternative fuels are found to be more prominent. The ordered probit model to examine the factors posing risk to respiratory illness reveal that women are at higher risk of developing respiratory syndromes as they spend more time in cooking space. While among others, smoking habit and age of the person are significant in increasing the risk pulmonary syndromes. JEL: I15, I38, Q52, Q58

Authors: Rogers Emma E. , Allan Carla C. , Zoromski Allison K. , Perez Crawford Trista , Moody Simone Sherman , Owens Julie Sarno 
Published: November 2021

Objective: This study aimed to (1) examine benchmarks for the benefits of the Daily Report Card (DRC) within a therapeutic recreation setting, that is, the Summer Treatment Program (STP) and (2) explore differences in baseline characteristics and treatment outcomes among optimal and suboptimal responders. Benchmarks were examined for children’s DRC target behaviors using standardized mean difference (SMD) effect sizes (ES) across 2-week periods of the STP. Method: Participants were 38 children attending an STP. Results: Aside from teasing, all DRC targets showed improvement by the second 2-week period that was sustained through the third 2-week period. Optimal responders demonstrated greater improvement in parent-rated impairment and camp behaviors than suboptimal responders. Some baseline differences between responder groups were found. Conclusion: This study provides the first benchmarks for change in DRC targets within a therapeutic recreational setting, offering guidelines for treatment expectations. Implications for clinical decision-making, treatment planning, and future research are discussed.
OCTA in macular intraretinal microvascular abnormalities: Retinal vascular density remodeling after panretinal photocoagulation
Authors: Fossataro Federica , Rispoli Marco , Pece Alfredo 
Published: November 2021

Purpose To describe a case of macular intraretinal microvascular abnormality (IRMA) detected with Optical Coherence Tomography Angiography (OCTA) and to show its remodeling and vascular density changes after panretinal photocoagulation (PRP) during an 18-month follow-up. Methods Case report. Results A 22-year-old female patient with proliferative diabetic retinopathy was found to have a small hyperreflective formation with posterior shadow cone and signal flow, located at the temporal margin of the fovea avascular zone (FAZ), identified as macular IRMA with OCTA. Her best-corrected-visual acuity was 20/20. Four months later the macular IRMA was larger and, in its context, there was also an increase in the flow area in B-scan. The patient underwent PRP and after 18 months we observed a regression of macular IRMA and an increase in the superficial capillary plexus vessel density in all sectors in comparison to baseline. Conclusion OCTA is a non-invasive tool that recognize macular IRMA in diabetic retinopathy patient and it could be helpful to follow their qualitative and quantitative vascular evolution over time.

Published: November 2021

Background: Identifying key variables that predict sleep quality in youth athletes allows practitioners to monitor the most parsimonious set of variables that can improve athlete buy-in and compliance for athlete self-report measurement. Translating these findings into a decision-making tool could facilitate practitioner willingness to monitor sleep in athletes. Hypothesis: Key predictor variables, identified by feature reduction techniques, will lead to higher predictive accuracy in determining youth athletes with poor sleep quality. Study Design: Cross-sectional study. Level of Evidence: Level 3. Methods: A group (N = 115) of elite youth athletes completed questionnaires consisting of the Pittsburgh Sleep Quality Index and questions on sport participation, training, sleep environment, and sleep hygiene habits. A least absolute shrinkage and selection operator regression model was used for feature reduction and to select factors to train a feature-reduced sleep quality classification model. These were compared with a classification model utilizing the full feature set. Results: Sport type, training before 8 am, training hours per week, presleep computer usage, presleep texting or calling, prebedtime reading, and during-sleep time checks on digital devices were identified as variables of greatest influence on sleep quality and used for the reduced feature set modeling. The reduced feature set model performed better (area under the curve, 0.80; sensitivity, 0.57; specificity, 0.80) than the full feature set models in classifying youth athlete sleep quality. Conclusion: The findings of our study highlight that sleep quality of elite youth athletes is best predicted by specific sport participation, training, and sleep hygiene habits. Clinical Relevance: Education and interventions around the training and sleep hygiene factors that were identified to most influence the sleep quality of youth athletes could be prioritized to optimize their sleep characteristics. The developed sleep quality nomogram may be useful as a decision-making tool to improve sleep monitoring practice among practitioners.

Authors: Greiner Justin J. , Trotter Cameron A. , Walczak Brian E. , Hetzel Scott J. , Baer Geoffrey S. 
Published: November 2021

Background: The Pitch Smart guidelines aim to limit youth baseball pitching behaviors associated with overuse injuries. Despite many youth baseball leagues being compliant with the guidelines, during tournaments, pitch count restrictions or guidelines are often not followed. Purpose: To perform a quantitative analysis of pitch counts in youth baseball players and evaluate compliance with regard to the Pitch Smart guidelines in the tournament setting. Study Design: Cross-sectional study; Level of evidence, 3. Methods: Included in the analysis were 100 youth baseball teams that competed in the 8-and-under to 14-and-under age divisions during the 2019 tournament season. Pitching data were compared with the Pitch Smart guidelines. Violations were identified as (1) exceeding maximum daily pitch count, (2) inadequate rest between pitching events, and (3) pitching more than 1 event on the same day. Pitcher and game factors were analyzed for possible relationships to guideline violations using mixed-effects negative binomial regression models, with comparisons of violations using rate ratios (RRs). Results: Analysis included 1046 pitchers and 2439 games. There were 1866 total Pitch Smart guideline violations, with 48.6% of pitchers having at least 1 violation. Inadequate rest was the most common reason for violation, with noncompliance occurring in 43.3% of pitchers. The highest rate of any violation (0.32 per appearance) occurred in the 8-and-under age division. High-volume pitchers had increased violation rates in each category compared with low-volume pitchers ( P < .001). Violation rates were increased more than twice the rate when pitchers participated in ≥5 consecutive games without a rest day when compared with a single game (RR, 2.48; P < .001). Conclusion: Noncompliance with Pitch Smart guidelines in tournament settings occurred in more than 90% of teams and almost half of all pitchers. Factors associated with noncompliance included younger pitcher age, high-volume pitching, and pitching in multiple consecutive games. Education of tournament directors, coaches, parents, and athletes regarding pitching guidelines is warranted in order to limit the risk of injury.

Published: November 2021

Background Sex differences in stroke outcomes have been noted, but whether this extends to stroke recurrence is unclear. We examined sex differences in recurrent stroke using data from the Platelet-Oriented Inhibition in New TIA and Minor Ischemic Stroke (POINT) trial. Patients and methods We assessed the risk of recurrent stroke in women compared to men using data from the POINT trial. Adults >18 years old were randomized within 12 hours of onset of minor ischemic stroke or transient ischemic attack (TIA), and followed for up to 90 days for ischemic stroke, our primary outcome. We used Cox proportional hazards model adjusted for demographics and stroke risk factors to evaluate the association between sex and stroke recurrence. We used interaction term testing and prespecified subgroup analyses to determine if the association between sex and recurrent stroke differed by age (<60 versus >60 years old), locale (US versus non-US), and index event type (stroke versus TIA). Last, we evaluated whether sex modified the effect of common stroke risk factors on stroke recurrence. Results Of 4,881 POINT trial participants with minor stroke or high-risk TIA, 2,195 (45%) were women. During the 90-day follow-up period, 267 ischemic strokes occurred; 121 were in women and 146 in men. The cumulative risk of recurrent ischemic stroke was not significantly different among women (5.76%; 95% CI, 4.84%–6.85%) compared to men (5.67%; 95% CI, 4.83%–6.63%). Women were not at a different risk of recurrent ischemic stroke compared to men (hazard ratio [HR], 1.02; 95% CI, 0.80–1.30) in unadjusted models or after adjusting for covariates. However, there was a significant interaction of age with sex (P=0.04). Among patients <60 years old, there was a non-significantly lower risk of recurrent stroke in women compared to men (HR 0.66; 95% CI 0.42–1.05). Last, sex did not modify the association between common stroke risk factors and recurrent stroke risk. Discussion and Conclusion Among patients with minor stroke or TIA, the risk of recurrent ischemic stroke and the impact of common stroke risk factors did not differ between men and women.

Aims We assessed the association of prior antiplatelet therapy (APT) at onset of intracerebral haemorrhage (ICH) with haematoma characteristics and outcome. Methods We performed a systematic review and meta-analysis of studies comparing ICH outcomes of patients on APT (APT-ICH) with patients not taking APT (non–APT-ICH). Primary outcomes were haematoma volume (mean difference and 95% CI), haematoma expansion (HE), in-hospital 3-month mortality rates and good functional outcome (modified Rankin Scale score 0–2). We provide odds ratios (ORs) from random effects models and subgroup analyses for haematoma expansion and short-term mortality rates. Results We included 23 of 1551 studies on 30,949 patients with APT-ICH and 62,018 with non-APT-ICH. Patients on APT were older (Δmean 6.27 years, 95% CI 5.44–7.10), had larger haematoma volume (Δmean 5.74 mL, 95% CI 1.93–9.54), higher short-term mortality rates (OR 1.44, 95% CI 1.14–1.82), 3-month mortality rates (OR 1.58, 95% CI 1.14–2.19) and lower probability of good functional outcome (OR 0.61, 95% CI 0.49–0.77). While there was no difference in HE in the overall analysis (OR 1.32, 95% CI 0.85–2.06), HE occurred more frequently when assessed within 24 h (OR 2.58, 95% CI 1.18–5.67). We found insufficient data for comparison of single versus dual APT-ICH. Heterogeneity was substantial amongst studies. Discussion APT is associated with larger baseline haematoma volume, early (<24 h) haematoma expansion, mortality rates and morbidity in patients with ICH. Data on differences in single and dual APT-ICH are scarce and warrant further investigation. New treatment options for APT-ICH are urgently needed.

Published: November 2021

Abstract
Background
Shoot branching is one of the important agronomic traits affecting yields and quality of tea plant (Camellia sinensis). Cytokinins (CTKs) play critical roles in regulating shoot branching. However, whether and how differently alternative splicing (AS) variant of CTKs-related genes can influence shoot branching of tea plant is still not fully elucidated.

Results
In this study, five AS variants of CTK biosynthetic gene adenylate isopentenyltransferase (CsA-IPT5) with different 3′ untranslated region (3ˊ UTR) and 5ˊ UTR from tea plant were cloned and investigated for their regulatory effects. Transient expression assays showed that there were significant negative correlations between CsA-IPT5 protein expression, mRNA expression of CsA-IPT5 AS variants and the number of ATTTA motifs, respectively. Shoot branching processes induced by exogenous 6-BA or pruning were studied, where CsA-IPT5 was demonstrated to regulate protein synthesis of CsA-IPT5, as well as the biosynthesis of trans-zeatin (tZ)- and isopentenyladenine (iP)-CTKs, through transcriptionally changing ratios of its five AS variants in these processes. Furthermore, the 3′ UTR AS variant 2 (3AS2) might act as the predominant AS transcript.

Conclusions
Together, our results indicate that 3AS2 of the CsA-IPT5 gene is potential in regulating shoot branching of tea plant and provides a gene resource for improving the plant-type of woody plants.

Abstract
Background
Tumor regression grade (TRG) after neoadjuvant therapy is reportedly predictive of prognosis in esophageal cancer patients, as lack of a response to neoadjuvant therapy is associated with a poor prognosis. However, there is little information available on the timing and pattern of recurrence after esophagectomy for thoracic esophageal squamous cell carcinoma (TESCC) that takes into consideration TRG after neoadjuvant chemoradiotherapy (NACRT). Here, in an effort to gain insight into a treatment strategy that improves the prognosis of NACRT non-responders, we evaluated the patterns and timing of recurrence in TESCC patients, taking into consideration TRG after NACRT.

Methods
A total of 127 TESCC patients treated with NACRT and esophagectomy between 2009 and 2017 were enrolled in this observational cohort study. TRGs were assigned based on the proportion of residual tumor cells in the area (TRG1, ≥1/3 viable cancer cells; 2, < 1/3 viable cancer cells; 3, no viable cancer cells). We retrospectively investigated the timing and patterns of recurrence and the prognoses in TESCC patients, taking into consideration TRG after NACRT.

Results
The 127 participating TESCC patients were categorized as TRG1 (42 patients, 33%), TRG2 (56 patients, 44%) or TRG3 (29 patients, 23%). The locoregional recurrence rate was higher in TRG1 (36.4%) patients than combined TRG2–3 (7.4%) patients. Patients with TRG3 had better prognoses, though a few TRG3 patients experienced distant recurrence. There were no significant differences in median time to first recurrence or OS among patients with locoregional or distant recurrence. There was a trend toward better OS in TRG2–3 patients with recurrence than TRG1 patients with recurrence, but the difference was not significant.

Conclusions
NACRT non-responders (TRG1 patients) experienced higher locoregional recurrence rates and earlier recurrence with distant or locoregional metastasis. TRG appears to be useful for establishing a strategy for perioperative treatments to improve TESCC patient survival, especially among TRG1 patients. (303 words).
